516 * unexelf.c: Don't assume ElfW (Half) fits in int.
517 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
518 when dealing with ElfW (Half) values, since they can exceed 2**31
519 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
520 (entry_address): Omit unused NUM arg. All uses changed.
522 2013-05-07 Juri Linkov <juri@jurta.org>

580 2013-05-06 Eli Zaretskii <eliz@gnu.org>
582 * xdisp.c (pos_visible_p): Use the special code for finding the
583 beginning of a display property or overlay for any "replacing"
584 display property, not just for display strings. This solves
585 incorrect reporting of position by posn-at-point. (Bug#14241)
587 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
589 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
590 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
591 Verify that ElfW (Half) fits in int.
592 (fatal): Use same signature as lisp.h.
593 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
594 configure and build with -DUNEXELF_DEBUG without worrying about
595 other modules that use DEBUG.
596 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
597 possibly-wide integers now uses it instead of plain fprintf.
598 (entry_address): New function, which avoids problems with 32-bit
599 overflow on 64-bit hosts.
600 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
601 (round_up): Don't assume the remainder fits in int.
602 (find_section): Use bool for boolean. Simplify debug code.
603 (unexec): Don't assume file sizes fit in int or size_t.
604 Omit unnecessary trailing newline in 'fatal' format.
605 Use strerror rather than outputting decimal error number.
606 Remove unused code when emacs is not defined;
607 this file relies on Emacs now.

610 * regex.c: Fix problems when DEBUG is defined.
611 (extract_number, extract_number_and_incr): Define regardless of
612 whether DEBUG is defined; that's simpler and makes the code less
613 likely to go stale in the normal case when DEBUG is not defined.
614 Return int rather than taking an int * arg. All callers changed.
615 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
616 Remove, replacing with ...
617 (DEBUG_PRINT): New macro. All callers changed.
618 (DEBUG_COMPILES_ARGUMENTS): New macro.

623 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
624 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
625 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
626 Don't assume ptrdiff_t, size_t, and long are the same width as int.
627 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
628 This matters only when DEBUG is defined.
630 2013-05-05 Eli Zaretskii <eliz@gnu.org>
632 * xdisp.c (set_iterator_to_next): Set the
633 ignore_overlay_strings_at_pos_p flag only if we are _really_
634 iterating over an overlay string, as indicated by the
635 current.overlay_string_index member. (Bug#14306)
637 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
639 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
640 to where it is used, to avoid autorelease issues (Bug#14050).
642 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
644 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
645 * fileio.c (syms_of_fileio): Implement this.
646 * filelock.c (create_lock_file): If symbolic links don't work, so
647 we use a regular file as a lock file, do not fsync the lock file;
650 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>

664 assertion violations. (Bug#14062)
666 2013-05-01 David Reitter <david.reitter@gmail.com>
668 * nsfns.m (ns_tooltip): Initialize.
670 2013-04-28 Eli Zaretskii <eliz@gnu.org>

693 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
695 * systime.h (make_timeval): Declare as 'const'.
697 2013-04-27 Kenichi Handa <handa@gnu.org>

702 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
704 Port better to AIX (Bug#14258).
705 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,

721 * w32fns.c (w32_fullscreen_rect): New function to compute the
722 window rectangle for the given fullscreen mode.
723 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
724 longer tunes the window size. This keeps the window's edges flush
725 with the screen and allows the taskbar to hide itself in fullboth.
727 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
728 window decorations and uses the entire screen.
730 * w32term.h (w32_fullscreen_rect) Add prototype.
731 (struct w32_output): Replace normal_width, normal_height,
732 normal_top, and normal_left members with a single normal_placement

751 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
752 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
753 parentheses where appropriate.
755 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
757 * keyboard.c (timer_start_idle): Remove no-longer-used local.
759 2013-04-14 Eli Zaretskii <eliz@gnu.org>
761 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
762 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
763 Mention in the doc string that setting these variables takes
764 effect only after a call to set-window-buffer. (Bug#14200)
766 2013-04-13 Eli Zaretskii <eliz@gnu.org>
768 * indent.c (Fvertical_motion): Don't consider display strings on
769 overlay strings as display strings on the buffer position we
770 started from. This prevents vertical cursor motion from jumping
771 more than one line when there's an overlay string with a display
772 property at end of line.
773 Reported by Karl Chen <Karl.Chen@quarl.org> in
774 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

779 already selected (bug#14191).
781 2013-04-11 Eli Zaretskii <eliz@gnu.org>
783 * window.c (Fwindow_end): Test more flags, including the buffer's
784 last_overlay_modified flag, to determine whether the window's
785 display is really up-to-date. Prevents the function from
786 returning a stale value. (Bug#14170)
787 (Fwindow_line_height): Fix the test for up-to-date-ness of the
790 2013-04-10 Eli Zaretskii <eliz@gnu.org>
792 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
793 garbaged only if it is not already the top frame on its TTY.
794 This prevents flickering due to constant redrawing of TTY frames when
795 there are GUI frames open in the same session. (Bug#13864)
797 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
799 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
800 of marking the idle timers directly.

826 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
829 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
831 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
832 This bug was introduced by my 2013-02-25 change that simplified
833 data_start configuration. Without this change, on GNU/Linux
834 an Emacs configured with --enable-profiling fails immediately
835 due to a profiler signal.
836 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
837 with these flags. On platforms where special flags are needed
838 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
839 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
840 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
842 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

914 Prefer < to > in range checks such as 0 <= i && i < N.
915 This makes it easier to visualize quantities on a number line.
916 This patch doesn't apply to all such range checks,
917 only to the range checks affected by the 2013-03-24 change.

1003 * window.h (struct window): Replace hchild, vchild and buffer slots
1004 with the only contents slot. This is possible because each valid
1005 window may have either the child window (in vertical or horizontal
1006 combination) or buffer to display (for the leaf window). Using that,
1007 a lof of operations to traverse and/or change window hierarchies may
1008 be simplified. New member horizontal is used to distinguish between
1009 horizontal and vertical combinations of internal windows.
1010 (WINDOW_LEAF_P, WINDOW_HORIZONTAL_COMBINATION_P)

1038 (sync_window_with_frame_matrix_rows): Enforce live window.
1039 Use contents slot, not buffer, where appropriate.
1040 * frame.c (set_menu_bar_lines_1): Use WINDOW_VERTICAL_COMBINATION_P
1041 and WINDOW_HORIZONTAL_COMBINATION_P.
1042 (make_frame_visible_1): Simplify the loop.
1043 Use contents slot, not buffer, where appropriate.
1044 * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
1045 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1046 (expose_window_tree): Likewise.
1047 Use contents slot, not buffer, where appropriate.
1048 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1049 to avoid deleted windows. Use contents slot instead of buffer.
1050 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
1051 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

1072 (redisplay_window): ...both window markers are valid here,
1073 which is verified by eassert.

1217 2013-03-23 Eli Zaretskii <eliz@gnu.org>
1219 * w32term.c (w32fullscreen_hook): Use FRAME_NORMAL_WIDTH,
1220 FRAME_NORMAL_HEIGHT, and FRAME_PREV_FSMODE, instead of static
1221 variables, to save and restore frame dimensions.
1222 Use FRAME_NORMAL_LEFT and FRAME_NORMAL_TOP to restore frame position
1223 after returning from a 'fullscreen' configuration.

1310 New functions to provide defaults when no window system available.
1311 (FRAME_RES_X, FRAME_RES_Y): New macros.

1370 Use getFilename and getDirectory.
1371 (getFilename, getDirectory): New methods for EmacsSavePanel and
1373 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

1387 * coding.c (detect_ascii): New function.
1388 (detect_coding): Set coding->head_ascii and coding->eol_seen only
1389 when the source bytes are actually scanned. On detecting for

1391 source bytes directly.
1392 (produce_chars): Call insert_from_gap with the new arg 0.
1393 (encode_coding): Likewise.

1427 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1428 too so that these builds can use Cygwin's file conversion
1429 functions. (We've been building and linking cygw32.o all along
1430 and just not using it.)
1432 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1434 File synchronization fixes (Bug#13944).
1435 * Makefile.in (LIB_FDATASYNC): New macro.
1437 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
1438 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
1439 Don't worry about HAVE_FSYNC, since a substitute fsync is
1440 available if the system lacks one.
1441 (Fwrite_regin): Retry fsync if interrupted.
1443 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1445 * w32term.c (w32_read_socket): If the Emacs frame is being
1446 activated, call w32fullscreen_hook, to make sure the new frame
1447 dimensions are in effect. (Bug#13937)
1449 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1451 * xdisp.c (init_iterator): Simplify because both character and byte
1452 positions are either specified or -1. Add eassert. Adjust comment.
1453 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1454 character and byte positions can be obtained from marker.
1456 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1458 Static checking by Sun C 5.12.

1471 a function pointer type; the C Standard requires this.
1473 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1474 Include <sys/param.h> unconditionally, as that works elsewhere and
1475 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1476 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1479 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

1508 common file dialog code.
1510 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1511 can just use du like other systems.
1513 * coding.c (from_unicode_buffer): Declare.
1514 * coding.c (from_unicode_buffer): Implement.
1516 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1562 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1563 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1564 from Elisp via unread-command-events.
1566 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1567 functions to mean "no change".
1569 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1571 region-cache.c, scroll.c, search.c: Use bool for booleans.
1572 * lisp.h (compile_pattern):

1577 (search_regs_saved, Fregexp_quote):
1578 Use bool for boolean.
1579 * region-cache.c (region_cache_forward, region_cache_backward):
1580 Fix comments to match code: these functions return int, not boolean.
1582 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1584 * search.c (find_newline): Accept start and end byte positions
1585 as arguments and allow -1 if not known.
1586 (find_newline_no_quit): Likewise for start position.
1587 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1588 * bidi.c (bidi_find_paragraph_start): Pass byte position to

1590 * editfns.c (Fconstrain_to_field): Break long line.
1591 Adjust call to find_newline.
1592 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1599 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1601 print.c, process.c: Use bool for booleans.
1602 * lisp.h (wait_reading_process_output):

1617 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1619 * bidi.c (bidi_fetch_char): Swap first and second arguments
1620 to match other functions accepting character and byte positions.
1622 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1623 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1624 when you need just to move to the previous buffer position.
1625 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1627 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1643 byte position and adjust call to vmotion.
1644 (window_scroll_line_based): Likewise with call to compute_motion.
1646 (Frecenter): Adjust calls to vmotion.
1648 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1650 * lisp.h (list2i, list3i): New functions.

1700 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1702 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1703 * sysdep.c (list_system_processes)
1704 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1705 Make it a stub in this case; otherwise the build might fail,
1706 and this code hasn't been tested on such hosts anyway.
1707 Problem reported by Nelson H. F. Beebe in
1708 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1709 and analyzed by Jérémie Courrèges-Anglas in
1710 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1712 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1714 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1715 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1716 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1717 * bidi.c (bidi_find_paragraph_start): Likewise.
1718 * indent.c (vmotion): Likewise.
1720 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1722 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1723 * filelock.c: Include <c-ctype.h>.
1724 (MAX_LFINFO): New top-level constant.
1725 (lock_info_type): Remove members pid, boot_time. Add members at,
1726 dot, colon. Change user member to be the entire buffer, not a
1727 pointer. This allows us to handle the case where a foreign
1728 pid or boot time exceeds the local range. All uses changed.
1729 (LINKS_MIGHT_NOT_WORK): New constant.
1730 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1731 (defined_WINDOWSNT): Remove.
1732 (MAKE_LOCK_NAME, file_in_lock_file_name):
1733 Always use .#FILE (not .#-FILE) for the file lock,
1734 even if it is a regular file.
1735 (rename_lock_file): New function.
1736 (create_lock_file): Use it.
1737 (create_lock_file, read_lock_data):
1738 Prefer a symbolic link for the lock file, falling back on a
1739 regular file if symlinks don't work. Do not try to create
1740 symlinks on MS-Windows, due to security hassles. Stick with
1741 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1742 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1743 host may be using a Windowsish file system, and cannot use
1744 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1745 doesn't work. Don't fail merely because of a symlink-contents
1746 length limit in the current file system; fall back on regular
1747 files. Increase the symlink contents length limit to 8 KiB, this
1748 should be big enough for any real use and doesn't crunch the
1750 (create_lock_file, lock_file_1, read_lock_data):
1751 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1752 (lock_file_1): Return error number, not bool. All callers changed.
1753 (ELOOP): New macro, if not already defined.
1754 (read_lock_data): Return size of lock file contents, not Lisp object.
1755 All callers changed. Handle a race condition if some other process
1756 replaces a regular-file lock with a symlink lock or vice versa,
1757 while we're trying to read the lock.
1758 (current_lock_owner): Parse contents more carefully, to help avoid
1759 confusing a regular-file lock with some other application's use
1760 of the file. Check for lock file contents being too long, or
1761 not parsing correctly.
1762 (current_lock_owner, lock_file):
1763 Allow foreign pid and boot times that exceed the local range.
1764 (current_lock_owner, lock_if_free, lock_file):
1765 Simplify allocation of lock file contents.
1766 * w32.c (sys_rename_replace): New function, containing most of
1767 the contents of the old sys_rename.
1768 (sys_rename): Use it.
1769 (fchmod): New dummy function.
1770 * w32.h (sys_rename_replace, fchmod): New decls.
1772 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1774 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1775 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1776 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1777 <dmantipov@yandex.ru>.
1779 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1781 * composite.c (get_composition_id, fill_gstring_header):
1782 Use make_uninit_vector where appropriate.
1783 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1784 * xselect.c (clean_local_selection_data): Likewise.
1786 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1788 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1789 * image.c (imagemagick_load_image): Calculate height and width
1790 after flattening the image, not before.
1792 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1794 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1795 * ftfont.c (ftfont_shape_by_flt): Likewise.
1796 * w32uniscribe.c (uniscribe_shape): Likewise.
1798 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1800 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1801 The old approach, which fell back on DIR/.#FILE.0 through
1802 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1803 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1804 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1805 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1806 because the locking mechanism was never reliable in that case).
1807 This patch fixes this and other bugs discovered by a code
1808 inspection that was prompted by
1809 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1810 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1811 to avoid interoperability problems between the MS-Windows and
1812 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1813 instances of Emacs now ignore each others' locks.
1814 * filelock.c (defined_WINDOWSNT): New constant.
1815 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1816 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1817 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1818 regular files on MS-Windows hosts.
1819 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1820 Use SAFE_ALLOCA to avoid problems with long file names.
1821 (MAX_LFINFO): Now a local constant, not a global macro.
1822 (IS_LOCK_FILE): Remove.
1823 (lock_file_1): Don't inspect errno if symlink call succeeds;
1824 that's not portable.
1825 (lock_file): Document that this function can return if lock
1827 (lock_file): Don't access freed storage.
1829 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1831 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1833 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1835 * textprop.c: Use bool for booleans.
1836 (validate_interval_range, Fadd_text_properties)
1837 (Fremove_text_properties): Prefer bool to int when either works.
1839 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1841 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1842 If the interval tree changes as a side effect of calling
1843 modify_region, re-do processing starting from the call to
1844 validate_interval_range. (Bug#13743)
1846 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1848 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1851 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1853 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1854 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1855 access to the lock file until it is written and closed.
1858 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1860 * callint.c (Qcall_interactively):
1861 * macros.c (Qexecute_kbd_macro):
1864 2013-02-26 Bastien Guerry <bzg@gnu.org>
1866 * window.c (Frecenter): Tiny docstring enhancement.
1868 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1870 Minor textprop integer cleanup.
1871 * intervals.h, textprop.c (add_text_properties_from_list):
1872 Return void, not int, since nobody uses the return value.
1873 * textprop.c (validate_plist, add_properties, remove_properties)
1874 (Fadd_text_properties):
1875 Don't assume list length fits in int.
1876 (interval_has_all_properties, interval_has_some_properties)
1877 (interval_has_some_properties_list, add_properties, remove_properties)
1878 (Fadd_text_properties, Fremove_text_properties)
1879 (Fremove_list_of_text_properties, text_property_stickiness):
1880 Use bool for booleans.
1881 (Fadd_text_properties, Fremove_text_properties):
1882 (Fremove_list_of_text_properties):
1883 Reindent do-while as per GNU style.
1885 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1887 Implement CLASH_DETECTION for MS-Windows.
1889 * filelock.c [WINDOWSNT]: Include w32.h.

1891 function of that name. Up-case the macro arguments.
1892 (IS_LOCK_FILE): New macro.
1893 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1894 (create_lock_file): New function, with body extracted from

1897 the lock information as its contents.
1898 (read_lock_data): New function, on Posix platforms just calls
1900 [WINDOWSNT]: Read the lock info from the file.
1901 (current_lock_owner): Call read_lock_data instead of calling
1902 emacs_readlinkat directly.
1903 (lock_file) [WINDOWSNT]: Run the file name through
1906 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1907 just check if the process by that PID exists.
1909 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1910 also present, as doing so will fail to error out if the file
1913 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1915 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1916 (Fremove_list_of_text_properties): Skip all of the intervals in
1917 the region between START and END that already have resp. don't
1918 have the requested properties, not just the first one.
1919 Add assertions that the loop afterwards always modifies the
1920 properties. (Bug#13743)
1922 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1924 * callint.c (Fcall_interactively): Use the right lexical environment

1933 (START_FILES): Remove. All uses removed.
1934 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1935 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1936 (buildobj.h): Use it.
1937 ($(ALLOBJS)): Depend on globals.h.
1938 (temacs$(EXEEXT)): Use $(ALLOBJS).
1939 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1940 * deps.mk (vm-limit.o):
1941 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1942 Do not depend on mem-limits.h.
1943 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1944 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1949 (make_hdr): Use DATA_START instead of start_of_data.
1950 * vm-limit.c: Move most of mem-limits.h's contents here.
1951 (data_start): New decl. It's OK if this is approximate,
1952 so simplify-away some unnecessary exactness.
1953 (POINTER): Remove; all uses removed.
1954 (data_space_start): Now char *, to avoid casts.
1955 (exceeds_lisp_ptr): New function, replacing the old
1956 EXCEEDS_LISP_PTR macro. All uses changed.
1957 (check_memory_limits): Simplify and remove casts.
1958 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

1972 and diagnosed by Andreas Schwab in
1973 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1975 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1977 Assume C89 or better.
1978 * ralloc.c (SIZE, POINTER, NIL):
1979 * vm-limit.c (POINTER):
1980 Remove, replacing all uses with C89 equivalents. These old
1981 symbols were present only for porting to pre-C89 platforms.
1983 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1985 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1986 This avoids warning messages reported as part of Bug#13546.
1988 2013-02-21 Ken Brown <kbrown@cornell.edu>
1990 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1992 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1994 * sheap.c (report_sheap_usage): Prefer message1_nolog.

2001 2013-02-19 Daniel Colascione <dancol@dancol.org>
2003 * sheap.c (report_sheap_usage): Use message, not message1, so
2004 that we don't try to create a buffer while we're in the middle
2005 of dumping Emacs. Explain why.
2007 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2009 * search.c (find_newline): Return byte position in bytepos.

2019 (get_visually_first_element, move_it_vertically_backward):
2020 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
2022 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2024 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2025 resources were not orderly released.
2027 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2029 * xdisp.c (x_draw_vertical_border): For a window that is neither
2030 the leftmost nor the rightmost, redraw both the left and the right
2031 vertical borders. (Bug#13723)
2033 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

2042 * editfns.c (Fmessage, Fmessage_box):
2043 * callint.c (Fcall_interactively):
2044 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.

2048 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
2049 * frame.c (syms_of_frame): ... to here.
2051 2013-02-16 Eli Zaretskii <eliz@gnu.org>
2053 * w32.c (sys_chown): Remove unused function.
2055 * w32term.c <input_signal_count>: Declare 'volatile'
2056 unconditionally. (Bug#9066)
2058 * w32.c (set_errno): Reset h_errno and don't set it to any other
2059 value. Set errno instead.
2060 (check_errno): Reset h_errno.
2061 (sys_socket, socket_to_fd, sys_bind, sys_connect)
2062 (sys_gethostname, sys_getservbyname, sys_getpeername)
2063 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2064 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
2066 (sys_gethostbyname): Set h_errno only errors detected.
2068 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2070 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
2072 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2074 * keyboard.c (read_char): Fix calculation of auto-save time out
2075 when auto-save-timeout is less than 4. (Bug#13720)
2077 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
2078 time. Improve diagnostics in DebPrint. (Bug#13546)

2086 value that is out of bounds.
2087 (sys_accept): If fd is negative, do not set up the child_process

2099 (get_overlay_arrow_glyph_row, display_mode_element):
2100 (decode_mode_spec_coding, message3):
2101 * xfaces.c (face_at_string_position): Use bool for booleans.
2104 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2106 Fix AIX port (Bug#13650).
2107 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2108 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2109 was #undeffed earlier, so it cannot be used as a macro here.
2110 Use the constant and not the macro.
2112 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2114 * w32proc.c (new_child): If no vacant slots are found in
2115 child_procs[], make another pass looking for slots whose process
2116 has exited or died. (Bug#13546)
2118 * w32.c (sys_pipe): When failing due to file descriptors above
2119 MAXDESC, set errno to EMFILE.
2120 (_sys_read_ahead): Update cp->status when failing to read serial
2121 communications input, so that the status doesn't stay at
2122 STATUS_READ_IN_PROGRESS. (Bug#13546)
2124 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2126 * gtkutil.c (tb_size_cb): New function.
2127 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2129 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2131 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2134 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2136 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2138 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

2148 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2150 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2152 Improve AIX port some more (Bug#13650).
2153 With this, it should be as good as it was in 23.3, though it's
2154 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2155 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2156 * unexaix.c (start_of_text): Remove.
2157 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2158 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2159 (orig_load_scnptr, orig_data_scnptr):
2160 Now off_t, not long, since they are file offsets.
2161 (make_hdr): Use _data, not start_of_data ().
2162 This is the key part of the fix.
2163 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2164 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2166 * pre-crt0.c (data_start): Initialize to 1.
2167 This ports to compilers that optimize the external declaration
2168 'int x = 0;' as if it were 'int x;' to shrink the executable.
2170 Improve AIX port (Bug#13650).
2171 This doesn't fix the bug, but it makes progress: Emacs builds now.
2172 * unexaix.c: Include inttypes.h, stdarg.h.
2173 (report_error, report_error_1): Mark as _Noreturn.
2174 (report_error): Don't report the wrong errno.
2175 (report_error_1): Now varargs. All callers changed.
2176 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2177 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2178 (write_ptr): Use %p to print address rather than %lx and a cast
2179 to unsigned long. Grow buffer a bit, to be safer.
2181 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2183 * bidi.c (bidi_resolve_neutral): After finding the next
2184 non-neutral character, accept NEUTRAL_ON type as well, because
2185 directional control characters, such as LRE and RLE, have their
2186 type converted to that by bidi_resolve_weak. This avoids aborts
2187 when LRE/RLE follows a run of neutrals.
2188 (bidi_move_to_visually_next): Assert that return value of
2189 bidi_peek_at_next_level is non-negative. Negative values will
2192 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2194 Minor getenv-related fixes.
2195 * callproc.c (Fcall_process_region) [!DOS_NT]:
2196 Avoid unnecessary duplicate call to getenv.
2197 * callproc.c (init_callproc):
2198 * dispnew.c (init_display):
2199 * sysdep.c (sys_subshell):
2200 Omit unnecessary cast of getenv or egetenv.
2202 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2204 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2205 Update dependencies.
2207 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2209 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2211 (display_line): Set w->region_showing to the value of
2212 it->region_beg_charpos, not to -1. This fixes redisplay
2213 optimization when cursor is moved up after M->. (Bug#13623)
2215 (try_scrolling): Scroll text up more if point is too close to ZV
2216 and inside the scroll margin. This makes sure point is moved
2217 outside the scroll margin in these cases.
2219 * window.h (struct window): region_showing can no longer be
2222 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2224 Tune by using memchr and memrchr.
2225 * doc.c (Fsnarf_documentation):
2226 * fileio.c (Fsubstitute_in_file_name):
2227 * search.c (find_newline, scan_newline):
2228 * xdisp.c (pos_visible_p, display_count_lines):
2229 Use memchr and memrchr rather than scanning byte-by-byte.
2230 * search.c (find_newline): Rename from scan_buffer.
2231 Omit first arg TARGET, as it's always '\n'. All callers changed.
2233 Clean up read_key_sequence a tiny bit more.
2234 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2235 (read_key_sequence): Remove unused locals.
2237 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2239 Clean up read_key_sequence a bit; reread active keymaps after first event.
2240 * keyboard.c (read_char, read_char_x_menu_prompt)
2241 (read_char_minibuf_menu_prompt):
2242 Replace nmaps+maps with a single `map' arg.
2243 (follow_key): Operate on a single map.
2244 (active_maps): New function.
2245 (test_undefined): Also return true for nil bindings.
2246 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2247 a single (composed) keymap. Remember `first_event' to choose the right
2248 set of active keymaps. Recompute the set of keymaps after receiving
2249 the first event. Remove GOBBLE_FIRST_EVENT.
2250 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2251 * keyboard.h (read_char): Update declaration.
2252 * lread.c (read_filtered_event): Adjust call to read_char.
2254 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2256 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2257 Don't use the limitation on backwards movement when lines are truncated
2258 in the window. (Bug#13675)
2260 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2262 * marker.c (set_marker_internal): If desired position is passed
2263 as a marker, avoid call to buf_charpos_to_bytepos.
2264 * window.c (Fset_window_point): Omit redundant type checking.
2265 (Fset_window_start): Likewise. Format comment.
2266 (window_scroll_pixel_based): Use set_marker_restricted_both
2267 with character and byte positions obtained from an iterator.
2268 (Fset_window_configuration): Use set_marker_restricted_both.
2269 * xdisp.c (message_dolog): Likewise.
2271 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2273 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2274 When text lines are longer than window's screen lines, don't move back
2275 too far. This speeds up some redisplay operations. (Bug#13675)
2277 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2279 * syntax.c (scan_sexps_forward): Fix byte position calculation
2280 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2282 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2284 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2285 that was not needed.
2287 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2289 Minor hashing refactoring.
2290 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2291 (sxhash_float): Return EMACS_UINT, for consistency with the other
2293 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2294 non-static inline function and therefore can't use static vars.
2295 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2296 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2297 with the other hash functions.
2299 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2301 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2302 XXXXXX part of the temporary file pattern is not downcased even
2303 when w32-downcase-file-names is non-nil. (Bug#13661)
2305 * xdisp.c (decode_mode_spec): Remove handling of %t.
2307 * msdos.c (careadlinkatcwd): Remove.

2325 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2327 * lisp.h (make_uninit_vector): New function.
2328 * alloc.c (Fvector, Fmake_byte_code):

2344 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2346 * coding.c (Fdefine_coding_system_internal): Use AREF where
2347 argument is known to be a vector.
2348 * fns.c (Flocale_info): Likewise for ASET.
2349 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2350 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2352 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2354 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2357 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2358 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
2359 updateCollectionBehaviour.
2361 * nsterm.m (NEW_STYLE_FS): Remove.
2362 (ns_last_use_native_fullscreen): New variable.
2363 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2364 (x_set_window_size): Do not take title bar and tool bar into account
2365 if isFullscreen returns YES.
2366 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2367 (check_native_fs): New function.
2368 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2369 (ns_term_init): Remove NEW_STYLE_FS.
2370 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2371 and tool bar if isFullscreen returns NO.
2372 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2373 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2374 with HAVE_NATIVE_FS.
2375 (window:willUseFullScreenPresentationOptions:): New method.
2376 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
2377 Hide toolbar if not enabled (Bug#13444).
2378 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
2379 Restore tool bar if enabled, hide it otherwise (Bug#13444).
2380 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
2381 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
2382 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
2383 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
2384 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2385 (syms_of_nsterm): Add ns-use-native-fullscreen.
2387 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2389 * fileio.c (Qchoose_write_coding_system): Now static.
2391 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2393 * xdisp.c (window_buffer_changed): region_showing can be negative,
2394 which still means region is being displayed.
2395 (redisplay_internal): Resurrect code that forced redisplay of the
2396 whole window when showing region and the mark has changed.
2397 Record the new mark position to allow redisplay optimizations.
2398 (display_line): If it->region_beg_charpos is non-zero, set the
2399 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2401 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2402 not bitfield of 1 bit.
2404 2013-02-03 Daniel Colascione <dancol@dancol.org>
2406 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2407 daemon mode works on cygw32 when Emacs is installed and not just
2410 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2412 Avoid file time stamp bug on MS-Windows (Bug#13149).
2413 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2414 as FAT32 doesn't update time stamps when truncating them.
2415 Also, check that a file time stamp is not a multiple of 100 ns;
2416 this should catch all instances of the problem on MS-Windows,
2417 as its native file system resolution is 100 ns or worse, and
2418 checking for a non-multiple of 100 ns should impose only a small
2419 overhead on systems with ns resolution.
2421 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2423 Avoid encoding file names on MS-Windows when they need to be run
2424 through dostounix_filename.
2425 * w32.c (normalize_filename): Accept an additional argument
2426 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2427 downcase it even if w32-downcase-file-names is non-nil.
2428 (dostounix_filename): Accept an additional argument MULTIBYTE and
2429 pass it to normalize_filename.
2430 (emacs_root_dir): Adjust.
2432 * msdos.h (dostounix_filename): Adjust prototype.
2434 * w32.h (dostounix_filename): Adjust prototype.
2436 * msdos.c (dostounix_filename): Accept an additional argument and
2438 (init_environment): Adjust callers of dostounix_filename.
2440 * fileio.c (Ffile_name_directory, file_name_as_directory)
2441 (directory_file_name, Fexpand_file_name)
2442 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2444 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2446 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2447 variables, as egetenv is case-insensitive for DOS_NT.
2449 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2450 with an encoded file name.
2452 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2453 Adjust calls to dostounix_filename.
2455 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2457 * unexw32.c (unexec): Adjust call to dostounix_filename.
2459 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2461 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2464 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2467 * callproc.c (Fcall_process): Make sure program name in PATH and
2468 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2469 is passed to exec/spawnve, which fails unless the file-name
2472 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2473 even if w32-quote-process-args is nil.
2475 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2477 Fix timestamp bug when write-region appends nothing (Bug#13149).
2478 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2479 the file's time stamp doesn't change if Emacs happens to write nothing
2480 to the file, and on a buggy file system this could cause Emacs to
2481 incorrectly infer that the file system doesn't have the bug.
2482 Avoid this problem by inhibiting the inference in this case.
2484 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2486 * window.h (struct window): Convert base_line_number, base_line_pos
2487 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2488 Convert region_showing member from Lisp_Object to bitfield.
2489 Remove sequence_number member. Adjust comments.
2490 * window.c (sequence_number): Remove.
2491 (make_window): Initialize column_number_displayed.
2492 * print.c (print_object): Follow the printed representation of
2493 frames and print window pointer to distinguish between windows.
2494 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2495 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2496 (wset_column_number_displayed, wset_region_showing): Remove.
2497 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2498 (try_scrolling, try_cursor_movement, redisplay_window)
2499 (try_window_reusing_current_matrix, try_window_id, display_line)
2500 (display_mode_lines, decode_mode_spec): Adjust users.
2501 * .gdbinit (pwinx): Do not print sequence_number.
2503 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2505 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2506 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2507 * dired.c: Include <fcntl.h>.
2508 (open_directory): New function, which uses open and fdopendir
2509 rather than opendir. DOS_NT platforms still use opendir, though.
2510 (directory_files_internal, file_name_completion): Use it.
2511 (file_attributes): New function, with most of the old Ffile_attributes.
2512 (directory_files_internal, Ffile_attributes): Use it.
2513 (file_attributes, file_name_completion_stat): First arg is now fd,
2514 not dir name. All uses changed. Use fstatat rather than lstat +
2516 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2517 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2518 (emacs_readlinkat): New function, with much of the old
2519 Ffile_symlink_p, but with an fd argument for speed.
2520 It uses readlinkat rather than careadlinkatcwd, so that it
2521 need not assume the working directory.
2522 (Ffile_symlink_p): Use it.
2523 * filelock.c (current_lock_owner): Use emacs_readlinkat
2524 rather than emacs_readlink.
2525 * lisp.h (emacs_readlinkat): New decl.
2526 (READLINK_BUFSIZE, emacs_readlink): Remove.
2527 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2528 (emacs_norealloc_allocator, emacs_readlink): Remove.
2529 This stuff is moved to fileio.c.
2530 * w32.c (fstatat, readlinkat): New functions.
2531 (careadlinkat): Don't check that fd == AT_FDCWD.
2532 (careadlinkatcwd): Remove; no longer needed.
2534 2013-01-31 Glenn Morris <rgm@gnu.org>
2536 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2537 (Fwrite_region): Update for new choose_write_coding_system args.
2538 Move the last piece of choose_write_coding_system here. (Bug#13522)
2539 (syms_of_fileio): Add choose-write-coding-system.
2541 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2543 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2544 (sys_close): Zero out the flags for the file descriptor before
2545 closing it. (Bug#13546)
2547 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2548 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2549 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2552 * w32.c (w32_get_long_filename, init_environment, readlink):
2553 Support file names encoded in DBCS codepages.
2554 (readlink): Use the current file-name-coding-system, not the ANSI
2555 codepage, to decode and handle targets of symlinks.
2557 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2559 * w32.c (opendir): Now accepts a 'const char *'.
2561 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2563 Remove obsolete redisplay code. See the discussion at
2564 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2565 * dispnew.c (preemption_period, preemption_next_check): Remove.
2566 (Vredisplay_preemption_period): Likewise.
2567 (update_frame, update_single_window, update_window, update_frame_1):
2568 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2569 used, following the 2012-06-22 change.
2571 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2573 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2575 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2577 * font.c (num_fonts): Remove the leftover from old
2578 debugging code. Adjust comment style here and there.
2579 * insdel.c (insert_1): Remove.
2580 * lisp.h (insert_1): Remove prototype.
2581 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2583 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2585 * w32.c (max_filename_mbslen): New function.
2586 (normalize_filename, readdir): Use it to detect locales where ANSI
2587 encoding of file names uses a double-byte character set (DBCS).
2588 If a DBCS encoding is used, advance by characters using
2589 CharNextExA, instead of incrementing a 'char *' pointer.
2590 Use _mbslwr instead of _strlwr. (Bug#13515)
2592 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2593 request of memory reservation to 1.7GB. (Bug#13065)
2595 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2597 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2598 at check_extra_latin label. (Bug#13505)
2600 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2602 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2603 Avoid redundant calls to strlen.
2605 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2607 Drop async_visible and async_iconified fields of struct frame.
2608 This is possible because async input is gone; for details, see
2609 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2610 * frame.h (struct frame): Remove async_visible and async_iconified
2611 members, convert garbaged to unsigned bitfield. Adjust comments.
2612 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2613 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2614 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2615 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2616 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2618 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2619 properly. Likewise for obscured.
2621 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2624 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2626 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2628 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2629 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2631 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2633 * xdisp.c (message2, message2_nolog): Remove functions.
2634 (message3, message3_nolog): Extract nbytes and multibyteness directly
2635 from the string. Change all callers.
2636 (message3_nolog): Don't set message_enable_multibyte since set_message
2637 will reset it anyway.
2638 (message1, message1_nolog): Use message3.
2639 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2640 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2641 (set_message): Drop all but the second arg, which has to be a string.
2642 (set_message_1): Simplify now that we know that a1 is NULL and the
2643 second arg is a string.
2644 * frame.h (struct frame): Remove `message_buf' field.
2645 Use glyphs_initialized_p instead.
2646 (FRAME_MESSAGE_BUF): Remove macro.
2647 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2648 * lisp.h (message2, message2_nolog): Remove declarations.
2649 (message3, message3_nolog): Update declarations.
2650 * keyboard.c (read_char_minibuf_menu_text)
2651 (read_char_minibuf_menu_width): Remove vars.
2652 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2653 to correctly handle multibyte strings.
2654 * frame.c (delete_frame): Don't free message_buf any more.
2655 * editfns.c (message_text, message_length): Remove vars.
2656 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2657 * fileio.c (auto_save_error): Use message3 instead of message2.
2658 * dispnew.c (adjust_frame_message_buffer): Remove function.
2660 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2662 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2663 real estate used for the tool bar and the menu bar.
2665 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2667 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2668 hidden buffer is prepared to modification (Bug#13164).
2670 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2672 * window.h (struct window): Change window_end_valid member from
2673 Lisp_Object to a bitfield. Adjust comments.
2674 (wset_window_end_valid): Remove.
2675 * window.c (adjust_window_count): Clear window_end_valid.
2676 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2677 (Fwindow_line_height, set_window_buffer, Frecenter)
2678 (Fsplit_window_internal, Fdelete_other_windows_internal)
2679 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2680 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2681 * xdisp.c (check_window_end, reconsider_clip_changes)
2682 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2683 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2684 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2686 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2688 * xdisp.c (mark_window_display_accurate): Simplify the loop
2689 assuming that the only one of vchild, hchild or buffer window
2690 slots is non-nil. Call mark_window_display_accurate_1 for
2691 the leaf windows only.
2692 (mark_window_display_accurate_1): Always assume leaf window.
2695 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2697 * emacs.c (Qkill_emacs_hook): Now static.
2699 * fileio.c (Finsert_file_contents): Simplify.
2700 Remove unnecessary assignments and tests.
2702 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2704 * w32.c (acl_set_file): Don't test for errors unless
2705 set_file_security returns FALSE. Avoids spurious errors when
2708 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2710 * fileio.c (Finsert_file_contents): Revert code introduced at
2711 2013-01-18 in favor of the simpler and generally better fix.
2712 Save stack space by removing 'buffer' and reusing 'read_buf'
2715 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2717 * lisp.h (eabs): Define unconditionally (Bug#13419).
2718 The old "#if !defined (eabs)" was an unnecessary revenant of back
2719 when this macro was called "abs". Document 'eabs' better.
2721 2013-01-19 Glenn Morris <rgm@gnu.org>
2723 * fns.c (Frandom): Doc fix.
2725 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2727 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2728 segfault when there are lots of overlays.
2730 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2731 when there are lots of overlays.
2732 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2733 for the details and a way to reproduce.
2735 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2737 * fileio.c: Use O_APPEND to append.
2738 This corresponds better to the natural interpretation of "append",
2739 and avoids the need to open the output file twice, or to invoke
2740 lseek when APPEND is neither nil nor a number.
2741 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2742 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2743 file possibly twice, and lseeking to its end; this avoids the
2744 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2745 at the same time: the combination is never needed and apparently
2746 it doesn't work with DOS_NT.
2748 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2749 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2751 Allow floating-point file offsets.
2752 Problem reported by Vitalie Spinu in
2753 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2754 * fileio.c (emacs_lseek): Remove.
2755 (file_offset): New function.
2756 (Finsert_file_contents, Fwrite_region): Use it.
2758 2013-01-19 Chong Yidong <cyd@gnu.org>
2760 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2761 aborting on Fsignal (Bug#13289).
2763 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2765 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2766 set_file_security as failure due to insufficient privileges.
2767 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2768 (fstat): Return owner and group like 'stat' and 'lstat' do.
2770 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2772 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2773 The bug was observed on Ubuntu operating inside a virtual machine,
2774 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2775 The workaround introduces a race condition on non-buggy hosts,
2776 but it's an unlikely race and anyway there's a nearly identical
2777 nearby race that can't be fixed.
2778 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2780 (Fwrite_region): Test for file system time stamp bug.
2781 (init_fileio): New function.
2782 * lisp.h (init_fileio): Declare it.
2783 * emacs.c (main): Call it.
2785 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2786 and make it more consistent with other stat-failure diagnostics.
2788 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2790 Fix crash when inserting data from non-regular files.

2797 gap and end positions after each read and so help make_gap to work
2798 properly. Do not signal an I/O error too early and so do not leave
2799 not yet decoded characters in a buffer, which was the reason of
2800 redisplay crash. Use list2 to build return value. Adjust comments.

3251 struct buffer_text to avoid accessing an uninitialized value
3252 when compact_buffer is called for the first time.
3253 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3254 (Fset_buffer_modified_p): Use buffer_window_count to check
3255 whether the buffer is displayed in some window.
3256 * xdisp.c (message_dolog): Likewise.
3258 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3260 * w32.c (acl_set_file): If setting the file security descriptor
3261 fails, and the new DACL is identical to the existing one, silently
3262 return success. This fixes problems for users backing up their
3263 own files without having the necessary privileges for setting
3264 security descriptors.
3266 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3268 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3269 after WaitForSingleObject returns normally. This expedites reader
3270 thread shutdown when delete_child triggers it.
3271 (reap_subprocess): More accurate commentary for why we call
3272 delete_child only when cp->fd is negative.
3274 * w32.c (sys_close): Do not call delete_child on a subprocess
3275 whose handle is not yet closed. Instead, set its file descriptor
3276 to a negative value, so that reap_subprocess will call
3277 delete_child on that subprocess when its SIGCHLD arrives.
3278 This avoids closing handles used for communications between sys_select
3279 and reader_thread, which doesn't give sys_select a chance to
3280 notice that the process exited and invoke the SIGCHLD handler for
3283 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3285 * nsfns.m (Fns_do_applescript): Run event loop until script has
3286 been executed (Bug#12969).
3287 (ns_run_ascript): Chech as_script for nil, set to nil after
3290 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3292 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3294 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3296 * w32term.c (w32fullscreen_hook): New function.
3297 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3299 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3301 * fileio.c (Finsert_file_contents): Doc fix.
3303 * w32proc.c (new_child, delete_child, find_child_pid): For a
3304 subprocess, consider its slot being in use as long as its process
3305 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3306 slot when a new process is started immediately after killing
3307 another one, without waiting enough time for the first process to
3308 be reaped and resources allocated for it be orderly freed.
3310 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3312 2012-12-21 Chong Yidong <cyd@gnu.org>
3314 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3316 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3318 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3320 * w32.c (get_name_and_id): Always pass NULL as the first argument
3321 of lookup_account_sid. Avoids crashes with UNC file names that
3322 refer to DFS domains, not to specific machine names. (Bug#12621)
3323 Remove now unused argument FNAME; all callers changed.
3324 (get_file_owner_and_group): Remove now unused argument FNAME; all
3327 2012-12-21 Chong Yidong <cyd@gnu.org>
3329 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3330 error for invalid chars, don't check for a nil return value.
3332 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3334 Avoid calls to CHAR_TO_BYTE if byte position is known.
3335 * editfns.c (make_buffer_string_both): Use move_gap_both.
3336 (Fbuffer_string): Use make_buffer_string_both.
3337 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3339 (buf_bytepos_to_charpos): Likewise.
3340 (charpos_to_bytepos): Remove.
3341 * fileio.c (Finsert_file_contents): Use move_gap_both.
3342 * search.c (Freplace_match): Likewise.
3343 * process.c (process_send_region): Likewise. Use convenient
3344 names for byte positions.
3345 * lisp.h (charpos_to_bytepos): Remove prototype.
3346 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3347 * insdel.c (move_gap): Likewise.
3349 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3351 * xdisp.c (redisplay_internal): Remove now-unused local.
3353 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3355 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3356 (redisplay_internal): Don't bother selecting the frame to get the
3357 proper value of frame-local variables (bug#13225).
3359 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3361 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3362 Rename 4th argument since it may be buffer or string. Adjust comment.
3363 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3365 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3367 * coding.c (Fdetect_coding_region): Do not check start and end with
3368 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3369 (code_convert_region): Likewise.
3371 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3373 * w32.c (acl_get_file, acl_set_file): Run the file name through
3374 map_w32_filename, and resolve any symlinks in the file name, like
3376 (acl_set_file): Call revert_to_self, if any privileges were
3379 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3381 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3382 ($(BLD)/w32.$(O)): Update dependencies.
3384 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3386 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3387 propagate redisplay's scrolling (if any) to the right window.
3388 (redisplay_internal): Use ensure_selected_frame.
3389 (display_mode_lines): Complete last fix.
3390 * window.c (select_window_1): New func, extracted from select_window.
3391 (select_window): Use it.
3392 * window.h (select_window_1): Declare.
3394 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3396 Emulate Posix ACL APIs on MS-Windows.
3397 * w32.c: Include sddl.h and sys/acl.h.
3398 (SDDL_REVISION_1): Define if not already defined.

3414 (acl_free, acl_get_file, acl_set_file): New functions.
3416 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3418 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3420 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3421 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3422 for some of that bug's symptoms can now cause Emacs to abort.
3423 Remove the workaround.
3424 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3425 The bug that caused SIGCHLD to get lost has been fixed, and the
3426 workaround for it can now cause Emacs to abort.
3428 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3430 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3431 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3432 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3434 2012-12-16 Romain Francoise <romain@orebokech.com>
3436 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3437 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3438 and copy ACL entries of file in addition to SELinux context if set.
3439 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3441 * Makefile.in (LIBACL_LIBS): New macro.
3444 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3446 * fileio.c (internal_delete_file): Use bool for boolean.
3448 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3450 Fix bug #13079 on MS-Windows with temp files not being deleted.

3453 (register_child): First argument is now pid_t.
3454 (record_infile, record_pending_deletion): New prototypes.
3456 * w32proc.c (new_child): Initialize input_file and
3457 pending_deletion members of the child.
3458 (delete_child): Delete the child's temporary input file, if any,
3459 that is pending deletion.
3460 (register_child): First argument is now pid_t.
3461 (record_infile, record_pending_deletion): New functions.
3462 (reap_subprocess): Fix a typo in DebPrint string.
3463 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3465 * fileio.c (internal_delete_file): Return an int again: non-zero
3466 if delete-file succeeds, zero otherwise.
3468 * lisp.h (internal_delete_file): Adjust prototype.
3470 * callproc.c (Fcall_process): Don't overwrite infile with result
3472 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3473 asynchronous subprocess, record the name of the input file name,
3475 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3476 delete the file, record it as pending deletion when the subprocess
3479 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3481 * editfns.c [HAVE_PWD_H]: Include grp.h.
3483 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3485 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3487 Fix permissions bugs with setgid directories etc. (Bug#13125)
3488 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3489 to mark it as a placeholder. The old value was often wrong.
3490 The only user of this attribute has been changed to use
3491 file-ownership-preserved-p instead, with its new group arg.
3492 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3494 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

3499 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3501 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3502 try to get accurate owner and group information from NT file
3503 security APIs. This is to make most callers of 'stat' and
3504 'lstat', which don't need that information, much faster.
3506 * dired.c (Ffile_attributes) [WINDOWSNT]:
3507 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3508 owner and group information from 'lstat'.
3510 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3512 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3513 as that confuses set-auto-coding, so insist on the head-read
3514 returning the full 1024 bytes. Let lseek compute the tail offset;
3515 less work for us. Do not ignore I/O errors when reading the tail.
3517 * xdisp.c: Minor style fixes.
3518 (init_iterator): Hoist assignment out of if-expression.
3519 (markpos_of_region): Callers now test for sign, not for -1.

3525 (init_iterator): Do not highlight the region of zero length.
3526 (redisplay_window): Check whether the region is of non-zero length.
3527 (try_cursor_movement): Allow if the region length is zero.

3530 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3532 * search.c (search_buffer): Check the inverse translations of each
3533 character in pattern when the buffer being searched is unibyte.
3536 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3538 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3539 files, fixing a regression from 24.2.
3540 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3542 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3544 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3545 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3546 Remove unnecessary S_ISLNK test, as (contra the comments) this
3547 function can't copy symlinks. Improve quality of error message
3548 when attempting to copy files that are neither regular files nor

3557 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3559 2012-12-12 Daniel Colascione <dancol@dancol.org>
3561 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3562 the dumped Emacs is not a sparse file, greatly improving Cygwin
3563 "make bootstrap" performance.
3565 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3567 * inotify.c (inotify_callback): Generate an Emacs event for every
3568 incoming inotify event.
3570 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3572 * xdisp.c (handle_face_prop): Fix logic of computing
3573 it->start_of_box_run_p.
3574 (append_space_for_newline): If the glyph row is R2L, reset the
3575 iterator's end_of_box_run_p flag before prepending the space glyph.
3576 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3577 iterator's start_of_box_run_p flag before prepending the stretch.
3578 (append_glyph, produce_image_glyph, append_composite_glyph)
3579 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3580 left_box_line_p and right_box_line_p flags of the glyph for R2L
3581 glyph rows. (Bug#13011)
3583 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

3588 * window.c (replace_buffer_in_windows_safely): Do nothing
3589 if buffer is not shown in a window.

3596 encoded_file_name, which is what it is.
3598 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

3630 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3631 (hinst): Remove unneeded extern declaration.
3632 (_start): Remove initialization of above variables; remove
3633 initialization of hinst, as cache_system_info now does that.

3742 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
3744 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
3746 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
3747 DWORD_PTR, for compatibility with 64-bit builds.
3749 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
3750 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
3751 (system_process_attributes): Use SIZE_T rather than DWORD, for

3758 2012-12-10 Eli Zaretskii <eliz@gnu.org>
3760 * indent.c (Fvertical_motion): If a display string will be
3761 displayed on the left or the right margin, don't consider it as a
3762 factor in cursor positioning. (Bug#13108)
3764 2012-12-10 Martin Rudalics <rudalics@gmx.at>
3766 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.

3773 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3775 * w32.c (unsetenv): Return 0 if the input string is too long.
3777 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3779 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3780 * alloc.c (xputenv): New function.
3781 * dbusbind.c (Fdbus_init_bus):
3783 * xterm.c (x_term_init):
3784 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
3785 * editfns.c (initial_tz): Move static var decl up.
3786 (tzvalbuf_in_environ): New static var.
3787 (init_editfns): Initialize these two static vars.
3788 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
3789 Save old TZ value on stack, if it's small.
3790 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
3791 instead, use xputenv+unsetenv to set and restore TZ.
3792 (environbuf): Remove static var. All uses removed.
3793 (Fset_time_zone_rule): Do not save TZ and environ;
3794 no longer needed here.
3795 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3796 Move to inside set_time_zone_rule; they don't need file scope any more.
3797 (set_time_zone_rule): Maintain the TZ=value string separately.
3798 (syms_of_editfns): Don't initialize initial_tz;
3799 init_editfns now does it.
3800 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3801 * lisp.h (xputenv): New decl.
3803 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3805 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3807 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3809 * w32.c (unsetenv, sys_putenv): New functions.
3811 2012-12-08 Chong Yidong <cyd@gnu.org>
3813 * editfns.c (Finsert_char): Make the error message more
3814 informative (Bug#12992).
3816 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3818 Simplify get_lim_data.
3819 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3820 Remove USG and vlimit methods; no longer used these days.
3821 Add #error catchall just in case.
3823 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3824 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3825 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3826 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3827 (deleted_pid_list, Fdelete_process, create_process)
3828 (record_child_status_change, handle_child_signal, deliver_child_signal)
3829 (init_process_emacs, syms_of_process):
3830 Assume SIGCHLD is defined.
3831 (parse_signal): Remove. All uses removed.
3832 (abbr_to_signal): New static function.
3833 (Fsignal_process): Use it to convert signal names to ints.
3834 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3835 kill (getpgrp (), ...).
3836 (emacs_sigaction_init): Assume SIGCHLD is defined.
3837 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3838 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

3840 All uses replaced by 'kill' with a negative pid.
3841 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3842 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3844 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3846 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3847 This will cause a production Emacs to dump core instead of
3850 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3852 * frame.c (make_frame): Do not set window's buffer to t.
3853 * window.c (Fsplit_window_internal): Likewise. Previously it was
3854 used to indicate that the window is being set up. Now we use
3855 set_window_buffer for all new windows, so the condition in ...
3856 (Fset_window_buffer): ... is always true and can be removed.
3858 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3860 Convenient macro to check whether the buffer is hidden.
3861 * buffer.h (BUFFER_HIDDEN_P): New macro.
3862 * frame.c (make_frame): Use it. Adjust comment.
3863 * buffer.c (candidate_buffer): New function.
3864 (Fother_buffer, other_buffer_safely): Use it.
3866 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3868 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3869 if the child process is still running. Instead, exit the wait
3870 loop and return zero. (Bug#13086)
3872 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3874 * frame.h (x_char_width, x_char_height): Remove prototypes.

3887 Fix a recently-introduced delete-process race condition.
3888 * callproc.c, process.h (record_kill_process):
3889 New function, containing part of the old call_process_kill.
3890 (call_process_kill): Use it.
3891 This does not change call_process_kill's behavior.
3892 * process.c (Fdelete_process): Use record_kill_process to fix a
3893 race condition that could cause Emacs to lose track of a child.
3895 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3897 Avoid code duplication between prev_frame and next_frame.
3898 * frame.c (candidate_frame): New function. Add comment.
3899 (prev_frame, next_frame): Use it. Adjust comment.
3901 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3903 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3904 fails, signal an error instead of continuing with an empty
3906 Encode expanded temp file pattern before passing it to mkstemp or
3909 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3910 Encode the file name before passing it to dostounix_filename, in
3911 case it will downcase it (under w32-downcase-file-names).
3914 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3916 Minor call-process cleanups.
3917 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3918 at the same time as other platforms, to simplify analysis.
3919 No need for fd0_volatile since we have synch_process_fd.
3920 Avoid needless emacs_close; arg is always negative.
3922 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3924 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3927 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3929 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3930 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3931 and mouse_face_hidden members to a bitfields.
3932 * frame.h (struct frame): Remove set-but-not-used space_width member.
3933 (FRAME_SPACE_WIDTH): Remove.
3934 * nsterm.m, w32term.c, xterm.c: Adjust users.
3935 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3936 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3937 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3938 members to a bitfields.
3940 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3942 Don't let call-process be a zombie factory (Bug#12980).
3943 Fixing this bug required some cleanup of the signal-handling code.
3944 As a side effect, this change also fixes a longstanding rare race
3945 condition whereby Emacs could mistakenly kill unrelated processes,
3946 and it fixes a bug where a second C-g does not kill a recalcitrant
3947 synchronous process in GNU/Linux and similar platforms.
3948 The patch should also fix the last vestiges of Bug#9488,
3949 a bug which has mostly been fixed on the trunk by other changes.
3950 * callproc.c, process.h (synch_process_alive, synch_process_death)
3951 (synch_process_termsig, sync_process_retcode):
3952 Remove. All uses removed, to simplify analysis and so that
3953 less consing is done inside critical sections.
3954 * callproc.c (call_process_exited): Remove. All uses replaced
3955 with !synch_process_pid.
3956 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3957 These take the role of what used to be in unwind-protect arg.
3959 (block_child_signal, unblock_child_signal):
3960 New functions, to avoid races that could kill innocent-victim processes.
3961 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3962 (call_process_kill): Record killed processes as deleted, so that
3963 zombies do not clutter up the system. Do this inside a critical
3964 section, to avoid a race that would allow the clutter.
3965 (call_process_cleanup): Fix code so that the second C-g works again
3966 on common platforms such as GNU/Linux.
3967 (Fcall_process): Create the child process in a critical section,
3968 to fix a race condition. If creating an asynchronous process,
3969 record it as deleted so that zombies do not clutter up the system.
3970 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3971 light of these changes. Omit unnecessary call to emacs_close
3972 before failure, as the unwind-protect code does that.
3973 * callproc.c (call_process_cleanup):
3974 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3975 * process.c (record_deleted_pid): New function, containing
3976 code refactored out of Fdelete_process.
3977 (Fdelete_process): Use it.
3978 (process_status_retrieved): Remove. All callers changed to use
3979 child_status_change.
3980 (record_child_status_change): Remove, folding its contents into ...
3981 (handle_child_signal): ... this signal handler. Now, this
3982 function is purely a handler for SIGCHLD, and is not called after
3983 a synchronous waitpid returns; the synchronous code is moved to
3984 wait_for_termination. There is no need to worry about reaping
3985 more than one child now.
3986 * sysdep.c (get_child_status, child_status_changed): New functions.
3987 (wait_for_termination): Now takes int * status and bool
3988 interruptible arguments, too. Do not record child status change;
3989 that's now the caller's responsibility. All callers changed.
3990 Reimplement in terms of get_child_status.
3991 (wait_for_termination_1, interruptible_wait_for_termination):
3992 Remove. All callers changed to use wait_for_termination.
3993 * syswait.h: Include <stdbool.h>, for bool.
3994 (record_child_status_change, interruptible_wait_for_termination):
3996 (record_deleted_pid, child_status_changed): New decls.
3997 (wait_for_termination): Adjust to API changes noted above.
3999 * bytecode.c, lisp.h (Qbytecode): Remove.
4000 No longer needed after 2012-11-20 interactive-p changes.
4002 2012-12-03 Eli Zaretskii <eliz@gnu.org>
4004 * xdisp.c (redisplay_window): If the cursor is visible, but inside
4005 the scroll margin, move point outside the margin. (Bug#13055)
4007 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
4009 * gtkutil.c (my_log_handler): New function.
4010 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4012 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4014 * lisp.h (modify_region): Rename to...
4015 (modify_region_1): ...new prototype.
4016 * textprop.c (modify_region): Now static. Adjust users.
4017 * insdel.c (modify_region): Rename to...
4018 (modify_region_1): ...new function to work with current buffer.
4019 Adjust comment and users. Use true and false for booleans.
4021 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4023 * alloc.c (free_save_value): New function.
4024 (safe_alloca_unwind): Use it.
4025 * lisp.h (free_save_value): New prototype.
4026 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4028 (save_excursion_restore): Adjust to match saved data structure.
4029 Use free_save_value to offload some work from GC. Drop obsolete
4032 2012-12-03 Chong Yidong <cyd@gnu.org>
4034 * fileio.c (Vauto_save_list_file_name): Doc fix.
4036 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4038 * w32fns.c: Remove prototype of atof.
4039 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
4041 (file_dialog_callback): Make it UINT_PTR.
4043 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
4046 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4047 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
4050 2012-12-03 Glenn Morris <rgm@gnu.org>
4052 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
4054 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
4056 Fix xpalloc confusion after memory is exhausted.
4057 * alloc.c (xpalloc): Comment fix.
4058 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4059 and signals an error, do not clear charset_table_size, as
4060 charset_table is still valid.
4061 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4063 Use execve to avoid need to munge environ (Bug#13054).
4064 * callproc.c (Fcall_process):
4065 * process.c (create_process):
4066 Don't save and restore environ; no longer needed.
4067 * callproc.c (child_setup):
4068 Use execve, not execvp, to preserve environ.
4070 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4072 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
4074 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4076 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
4077 display for sliced images (Bug#10500).
4079 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
4081 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
4083 * doc.c (Fdocumentation): Re-add handling of function-documentation,
4084 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4086 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4088 * xdisp.c (window_outdated): Remove eassert since it hits
4089 some suspicious corner cases (see Bug#13007 and Bug#13012).
4090 (mode_line_update_needed): New function.
4091 (redisplay_internal, redisplay_window): Use it.
4092 (ensure_selected_frame): New function.
4093 (redisplay_internal, unwind_redisplay): Use it.
4094 (redisplay_internal): Move comment about buffer_shared...
4095 (buffer_shared_and_changed): ...near to its real use.
4097 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
4099 * callproc.c (Fcall_process): Don't misreport vfork failure.
4101 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4103 * callproc.c (Fcall_process): Fix vfork portability problems.
4104 Do not assume that fd[0], count, filefd, and save_environ survive
4105 vfork. Fix bug whereby wrong errno value could be reported for
4106 pipe failure. Some minor cleanups, too, as follows. Move buf and
4107 bufsize to the context where they're needed. Change new_argv to
4108 be of type char **, as this is more convenient and avoids casts.
4109 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4110 Now local constants, not macros.
4112 2012-11-18 Kenichi Handa <handa@gnu.org>
4114 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
4115 for the variable "f".
4117 2012-11-13 Kenichi Handa <handa@gnu.org>
4119 * font.c (font_unparse_xlfd): Exclude special characters from the
4120 generating XLFD name.
4122 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
4124 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

4135 * lread.c (readbyte_from_file): Assume EINTR is defined.
4136 * process.c (wait_reading_process_output, send_process) [subprocesses]:
4137 Assume EIO and EAGAIN are defined.
4138 * unexcoff.c (write_segment): Assume EFAULT is defined.
4140 2012-11-27 Eli Zaretskii <eliz@gnu.org>
4142 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
4145 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
4146 highlighting on the frame was cleared. Prevents assertion
4147 violations when repeatedly clicking on the "Top" link of the
4148 "bread-crumbs" in Info buffers.
4150 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
4152 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
4154 2012-11-24 Ken Brown <kbrown@cornell.edu>

4157 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
4158 were always defined.
4160 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4162 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4163 between bpos_covered and bpos_max. This fixes cursor display when
4164 several display strings follow each other.
4166 * .gdbinit (pgx): If the glyph's object is a string, display the
4167 pointer to string data, rather than the value of the string object
4168 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4170 * indent.c (Fvertical_motion): If the starting position is covered
4171 by a display string, return to one position before that, to avoid
4172 overshooting it inside move_it_to. (Bug#12930)
4174 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4176 * frame.h (struct frame): Remove display_preempted member

4179 * w32menu.c (pending_menu_activation): Remove since not
4181 (set_frame_menubar): Adjust user.
4182 * w32term.h (struct x_output): Drop outdated #if 0 code.
4183 (struct w32_output): Use bitfields for explicit_parent,
4184 asked_for_visible and menubar_active members.
4185 Drop unused pending_menu_activation member.
4186 * xterm.h (struct x_output): Drop outdated #if 0 code.
4187 Use bitfields for explicit_parent, asked_for_visible,
4188 has_been_visible and net_wm_state_hidden_seen members.

4192 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4193 of a literal "/". (Bug#12955)
4194 (gl-stamp): Invoke fc.exe directly, not through cmd.
4196 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4198 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4199 * dired.c: Assume HAVE_DIRENT_H.
4200 (NAMLEN): Remove, replacing with ...
4201 (dirent_namelen): New function. All uses changed. Use the GNU macro
4202 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4203 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4204 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4205 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4207 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4208 * ndir.h: Rename to ../nt/inc/dirent.h.
4209 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4210 Do not include <dirent.h>; no longer needed.
4211 * w32.c: Include <dirent.h> rather than "ndir.h".
4213 2012-11-23 Chong Yidong <cyd@gnu.org>
4215 * xftfont.c (xftfont_open): Remove duplicate assignment.
4217 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4219 * alloc.c (Fgarbage_collect): Unblock input after clearing
4220 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4221 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4222 * msdos.c (IT_frame_up_to_date): Use it here...
4223 * w32term.c (w32_frame_up_to_date): ...here...
4224 * xterm.c (XTframe_up_to_date): ...and here...
4225 * nsterm.m (ns_frame_up_to_date): ...but not here.
4226 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4228 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4229 Do not check whether GC is in progress.
4231 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4233 * xdisp.c (window_buffer_changed): New function.
4234 (update_menu_bar, update_tool_bar): Use it to
4235 simplify large 'if' statements.
4236 (redisplay_internal): Generalize commonly used
4237 'tail' and 'frame' local variables.
4239 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4241 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4242 with Windows system header.
4244 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4246 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4247 * alloc.c: Assume unistd.h exists.
4248 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4249 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4250 (getwd) [USG]: Remove; no longer needed.
4251 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4252 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4253 * w32.h (getcwd): Remove decl.
4255 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4257 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4258 Make it set selected_window as well.
4259 (update_tool_bar): Use it.
4261 2012-11-21 Ken Brown <kbrown@cornell.edu>
4263 * emacs.c (main): Set the G_SLICE environment variable for all
4264 Cygwin builds, not just GTK builds. See
4265 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4267 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4269 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4270 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4271 Define for the MSVC compiler.
4273 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4275 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4276 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4277 dostounix_filename. Prevents crashes down the road, because
4278 dostounix_filename assumes it gets a unibyte string.
4279 Reported by Michel de Ruiter <michel@sentient.nl>, see
4280 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
4282 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

4286 * lread.c (init_obarray): Set `function' fields to Qnil.
4287 * eval.c (Fcommandp): Ignore Qunbound.
4288 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
4289 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
4290 Test NILP rather than Qunbound.
4291 (Ffmakunbound): Set to Qnil.
4292 (Fsymbol_function): Never signal an error.
4293 (Finteractive_form): Ignore Qunbound.
4295 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
4297 * eval.c (interactive_p): Remove no-longer-used decl.
4299 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4301 * xdisp.c (buffer_shared): Adjust comment.
4302 (buffer_shared_and_changed): New function.
4303 (prepare_menu_bars, redisplay_internal): Use it to
4304 decide whether all windows or frames should be updated.
4305 (window_outdated): New function.
4306 (text_outside_line_unchanged_p, redisplay_window): Use it.
4307 (redisplay_internal): Likewise. Fix indentation.
4309 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4311 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4312 (syms_of_eval): Remove corresponding defsubr.
4313 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4315 2012-11-19 Daniel Colascione <dancol@dancol.org>
4317 * w32fns.c (Fx_file_dialog):
4318 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4319 cygwin_convert_file_name*.
4321 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4322 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4324 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4326 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4328 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4330 * w32select.c: Include w32common.h before w32term.h, so that
4331 windows.h gets included before w32term.h uses some of its
4332 features, see below.
4334 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4336 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4338 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4340 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4342 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4343 (ns_select): Return at once if events are held (Bug#12834).
4345 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4347 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4348 Needed following 2012-10-20 change. (Bug#12902)
4350 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4352 * w32proc.c (waitpid): Remove unused label get_result.
4354 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4356 * makefile.w32-in (SYSWAIT_H): New macro.
4357 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4358 ($(BLD)/sysdep.$(O)): Update dependencies.
4360 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4362 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4363 * callproc.c (relocate_fd): Assume F_DUPFD.
4364 * emacs.c, term.c (O_RDWR): Remove.
4365 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4366 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4367 * nsterm.m: Assume <fcntl.h> exists.
4368 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4369 (create_pty, Fmake_network_process, server_accept_connection)
4370 (wait_reading_process_output, init_process_emacs):
4372 (wait_reading_process_output): Put in a special case for WINDOWSNT
4373 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4374 It's not clear this is needed, but it's a more-conservative change.
4375 (create_process): Assume FD_CLOEXEC.
4376 (create_process, create_pty): Assume O_NOCTTY.
4377 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4378 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4379 Omit if not DOS_NT, since F_GETFL is not defined there.
4380 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4381 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4383 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4384 lack it, since gnulib guarantees this.
4385 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4387 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4389 * w32.c (faccessat): Pretend that directories have the execute bit
4390 set. Emacs expects that, e.g., in files.el:cd-absolute.
4392 * w32proc.c (create_child): Don't clip the PID of the child
4393 process to fit into an Emacs integer, as this is no longer a
4395 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4396 reaping only the process specified by PID argument, if that is
4397 positive. Use PID instead of dead_child to know which process to
4398 reap. Wait for the child to die only if WNOHANG is not in
4400 (sys_select): Don't set dead_child.
4402 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4403 as it is no longer needed.
4405 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4407 (record_child_status_change): Remove the setting of
4408 record_at_most_one_child for the !WNOHANG case.
4410 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4412 Fix problems in ns port found by static checking.
4413 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4414 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4415 not to process group.
4416 (ns_select): Use emacs_write, not write, as that's more robust
4417 in the presence of signals.
4418 (fd_handler:): Check for read errors.
4420 2012-11-16 Glenn Morris <rgm@gnu.org>
4422 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4424 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4426 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4428 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4430 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4431 use the same value of thread handle.
4432 (start_timer_thread): If the timer thread exited (due to error),
4433 clean up by closing the two handles it used. Duplicate the caller
4434 thread's handle here, so it gets duplicated only once, when
4435 launching the timer thread. Set priority of the timer thread, not
4437 (getitimer): Don't duplicate the caller thread's handle here.
4440 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4442 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4445 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4447 Remove no-longer-used pty_max_bytes variable.
4448 * process.c (pty_max_bytes): Remove; unused.
4449 (send_process): Do not set it.
4451 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4453 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4454 Update dependencies.
4456 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4458 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4459 This follows up on the 2012-09-29 patch that removed indirection
4460 for the 'function' field. Reported by Sergey Vinokurov in
4461 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4463 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4465 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4466 different name, as the MS runtime does not have such a function,
4467 and probably never will.) All callers changed. Ignore DIRFD
4468 value if PATH is an absolute file name, to match Posix spec
4469 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4472 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4474 * xdisp.c (echo_area_display, redisplay_internal):
4475 Omit redundant check whether frame_garbaged is set.
4477 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4479 Use faccessat, not access, when checking file permissions (Bug#12632).
4480 This fixes a bug that has been present in Emacs since its creation.
4481 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4482 which must set some sort of record. (Torek's bug report was against
4483 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4484 same common flaw.) See Torek's Usenet posting
4485 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4486 Posted: Fri Apr 8 14:18:56 1983.
4487 * Makefile.in (LIB_EACCESS): New macro.
4489 * callproc.c (init_callproc):
4490 * charset.c (init_charset):
4491 * fileio.c (check_existing, check_executable, check_writable)
4493 * lread.c (openp, load_path_check):
4494 * process.c (allocate_pty):
4496 Use effective UID when checking permissions, not real UID.
4497 * callproc.c (init_callproc):
4498 * charset.c (init_charset):
4499 * lread.c (load_path_check, init_lread):
4500 Test whether directories are accessible, not merely whether they exist.
4501 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4502 * fileio.c (check_existing, check_executable, check_writable)
4504 Use symbolic names instead of integers for the flags, as they're
4506 (check_writable): New arg AMODE. All uses changed.
4507 Set errno on failure.
4508 (Ffile_readable_p): Use faccessat, not stat + open + close.
4509 (Ffile_writable_p): No need to call check_existing + check_writable.
4510 Just call check_writable and then look at errno. This saves a syscall.
4511 dir should never be nil; replace an unnecessary runtime check
4512 with an eassert. When checking the parent directory of a nonexistent
4513 file, check that the directory is searchable as well as writable, as
4514 we can't create files in unsearchable directories.
4515 (file_directory_p): New function, which uses 'stat' on most platforms
4516 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4517 (Ffile_directory_p, Fset_file_times): Use it.
4518 (file_accessible_directory_p): New function, which uses a single
4519 syscall for efficiency.
4520 (Ffile_accessible_directory_p): Use it.
4521 * xrdb.c (file_p): Use file_directory_p.
4522 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4523 * lread.c (openp): When opening a file, use fstat rather than
4524 stat, as that avoids a permissions race. When not opening a file,
4525 use file_directory_p rather than stat.
4526 (dir_warning): First arg is now a usage string, not a format.
4527 Use errno. All uses changed.
4528 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4529 that merely introduced a race.
4530 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4531 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4532 and similarly for the other O_* flags.
4533 * w32.c (sys_faccessat): Rename from sys_access and switch to
4534 faccessat's API. All uses changed.
4535 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4536 (magic_db): Rename from magic_file_p.
4537 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4538 char *, so that we don't have to test for file existence
4539 separately from opening the file for reading. This removes a race
4540 fixes a permission-checking problem, and simplifies the code.
4542 (file_p): Remove; no longer needed.
4544 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4546 Omit glyphs initialization at startup.
4547 * dispnew.c (glyphs_initialized_initially_p): Remove.
4548 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4549 (Fredraw_frame): Move actual code from here...
4550 (redraw_frame): ...to here. Add eassert. Adjust comment.
4551 (Fredraw_display): Use redraw_frame.
4552 * xdisp.c (clear_garbaged_frames): Likewise.
4554 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4556 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4557 passed to pint2str and pint2hrstr to be at most the size of the
4558 frame's decode_mode_spec_buffer. This avoids crashes with very
4559 large values of FIELD_WIDTH argument to decode_mode_spec.
4562 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4564 Fix a race with verify-visited-file-modtime (Bug#12863).
4565 Since at least 1991 Emacs has ignored an mtime difference of no
4566 more than one second, but my guess is that this was to work around
4567 file system bugs that were fixed long ago. Since the race is
4568 causing problems now, let's remove that code.
4569 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4570 whose time stamp is off by no more than a second. Insist that the
4571 file time stamps match exactly.
4573 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4575 * frame.h (struct frame): Convert external_tool_bar member to
4576 1-bit unsigned bitfield.
4577 * termhooks.h (struct terminal): Remove mouse_moved member since
4578 all users are long dead. Adjust comment on mouse_position_hook.
4580 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4582 Simplify by using FOR_EACH_FRAME here and there.
4583 * frame.c (next_frame, prev_frame, other_visible_frames)
4584 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4585 * w32term.c (x_window_to_scroll_bar): Likewise.
4586 * window.c (window_list): Likewise.
4587 * xdisp.c (x_consider_frame_title): Likewise.
4588 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4589 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4590 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4591 * xmenu.c (menubar_id_to_frame): Likewise.
4592 * xselect.c (frame_for_x_selection): Likewise.
4593 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4594 (x_window_to_menu_bar): Likewise.
4595 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4597 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4599 * data.c (Qdefalias_fset_function): Now static.
4601 Another tweak to vectorlike_header change.
4602 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4603 Remove, and replace all uses with ...
4604 (next_in_free_list, set_next_in_free_list):
4605 New functions, which respect C's aliasing rules better.
4607 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4609 * window.c (list4i): Rename from 'quad'. All uses changed.
4610 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4612 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4614 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4615 warning about mixing declarations and code in ISO C90.
4617 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4619 * window.c (Fsplit_window_internal): Set combination limit of
4620 new parent window to t iff Vwindow_combination_limit is t;
4621 fixing a regression introduced with the change from 2012-09-22.
4622 (Fset_window_combination_limit): Fix doc-string.
4624 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4626 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4627 amount when the scroll margins are too large. When scrolling
4628 backwards in the buffer, give up if cannot reach point or the
4629 scroll margin within a reasonable number of screen lines.
4630 Fixes point position in window under scroll-up/down-aggressively when
4631 point is positioned many lines beyond the window top/bottom.
4634 * ralloc.c (relinquish): If real_morecore fails to return memory
4635 to the system, don't crash; instead, leave the last heap
4636 unchanged and return. (Bug#12774)

4666 Tweak last vectorlike_header change.
4667 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4668 vectorlike object on the free list. This is introduced to avoid
4669 some (but not all) pointer casting and aliasing problems, see
4670 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4671 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4703 special hash function containing a comparison that always yields 1.
4705 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4707 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4708 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4709 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4712 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4714 * image.c (xpm_make_color_table_h): Fix compiler error because
4715 make_hash_table changed.
4717 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4719 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4721 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4723 Use ad-hoc comparison function for the profiler's hash-tables.
4724 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4725 (make_log): Use them.
4726 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4727 call Fequal any more.

4736 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4737 (hash_lookup, hash_remove_from_table): Move assertion checking of
4738 hashfn result here. Check hash-equality before calling cmpfn.

4751 value of w32-scroll-lock-modifier is neither nil nor one of the
4752 known key modifiers. (Bug#12806)
4754 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4756 Shrink struct vectorlike_header to the only size field.
4757 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4759 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4760 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

4762 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4763 information from the vector header. Adjust comment.

4784 (allocate_vectorlike): Likewise.
4785 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4786 Add easserts. Adjust XSETPVECTYPESIZE usage.
4787 (allocate_buffer): Use BUFFER_PVEC_INIT.
4788 (live_vector_p): Adjust to match large vector.
4789 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4790 * buffer.h (struct buffer): Add next member.
4791 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4793 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4799 (xvecsize): New command.
4801 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4803 * keyboard.c (event_to_kboard): Do not dereference
4804 frame_or_window field of SELECTION_REQUEST_EVENT
4805 and SELECTION_CLEAR_EVENT events (Bug#12814).
4806 * xterm.h (struct selection_input_event): Adjust comment.
4808 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4810 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4811 such as Scroll Lock, if the respective keys are treated as
4812 function keys, not as modifiers. This avoids destroying non-ASCII
4813 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4815 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4817 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4819 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4821 Restore some duplicate definitions (Bug#12814).
4822 This undoes part of the 2012-11-03 changes. Some people build
4823 with plain -g rather than with -g3, and they need the duplicate
4824 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4825 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4826 Define as macros, as well as as enums or as constants.
4828 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4830 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4831 to keypad keys (Bug#12816).
4833 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4835 Minor adjustments of recently-changed frame functions.
4836 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4837 known to be a frame (we're in the FRAMEP branch).
4838 * lisp.h (Qframep): Remove decl. frame.h declares this.
4839 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4840 since they're meant for Lisp fixnum values.
4842 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4844 * window.c (Fwindow_combination_limit): Revert to the only
4845 required argument and adjust docstring as suggested in
4846 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4847 by Martin Rudalics <rudalics@gmx.at>.
4849 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4851 Widely used frame validity and checking functions.
4852 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4853 * frame.c (decode_live_frame, decode_any_frame): New functions.
4854 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4855 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4856 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

4864 * lisp.h (frame_buffer_predicate): Remove prototype.
4865 * buffer.c (Fother_buffer): Use decode_any_frame.
4866 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4867 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4868 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4869 (Fclose_font, Ffont_info): Use decode_live_frame.
4870 * fontset.c (check_fontset_name): Likewise.
4871 * terminal.c (Fframe_terminal): Likewise.
4872 * w32fns.c (check_x_frame): Likewise.
4873 * window.c (Fminibuffer_window, Fwindow_at)
4874 (Fcurrent_window_configuration): Likewise.
4875 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4876 Likewise. Allow zero number of arguments. Adjust docstring.
4877 * dispnew.c (Fredraw_frame): Likewise.
4878 * xfaces.c (frame_or_selected_frame): Remove.
4879 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4880 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4881 (Fframe_face_alist): Use decode_live_frame.
4882 * xfns.c (check_x_frame): Likewise.
4884 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4886 * window.c (quad): New function.
4887 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4888 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4889 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4890 (Fwindow_line_height): Use it.
4891 (Fwindow_fringes): Use list3.
4892 (Fwindow_scroll_bars): Use list4.
4893 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4894 (Fwindow_combination_limit): Allow zero number of arguments.
4896 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4898 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4900 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4901 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4902 file descriptor 2 for standard error. (Bug#12805)
4904 2012-11-05 Chong Yidong <cyd@gnu.org>
4906 * process.c (wait_reading_process_output): Revert previous change.
4908 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4910 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4911 This removes code that has been obsolete since around 1990.
4912 * callproc.c (Fcall_process):
4914 * process.c (create_process):
4915 * term.c (dissociate_if_controlling_tty):
4916 Assume setsid exists.
4917 * callproc.c (child_setup): Assume setpgid exists and behaves as
4918 per POSIX.1-1988 or later.
4919 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4920 * emacs.c (shut_down_emacs):
4921 * sysdep.c (sys_suspend, init_foreground_group):
4922 Assume getpgrp behaves as per POSIX.1-1998 or later.
4923 * msdos.c (setpgrp): Remove.
4924 (tcgetpgrp, setpgid, setsid): New functions.
4925 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4926 * term.c (no_controlling_tty): Remove; unused.
4927 * w32proc.c (setpgrp): Remove.
4928 (setsid, tcgetpgrp): New functions.
4930 Simplify by assuming __fpending.
4931 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4932 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4933 Do not assume that __fpending's result fits in int.
4935 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4937 Remove EMACS_OUTQSIZE+sleep hack.
4938 * dispnew.c (update_frame_1): Remove hack for terminals slower
4939 than 2400 bps, which throttled Emacs by having it sleep.
4940 This code hasn't worked since at least 2007, when the multi-tty stuff
4941 was added, and anyway those old terminals are long dead.
4942 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4943 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4945 Fix data-loss with --version (Bug#9574).
4946 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4947 as we can't assume that emacs_strerror is initialized, and strerror
4948 is good enough here.
4949 (main): Invoke atexit earlier, to catch earlier instances of
4950 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4952 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4954 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4955 (keyDown): Remap keypad keys to X11 virtual key codes.
4957 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4959 Fix data-loss with --batch (Bug#9574).
4960 * emacs.c: Include <close-stream.h>.
4961 (close_output_streams): New function.
4962 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4963 and handles errors appropriately.
4964 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4967 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4968 The symptom is a diagnostic "GLib-WARNING **: In call to
4969 g_spawn_sync(), exit status of a child process was requested but
4970 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4971 waitpid(), so exit status can't be returned." The diagnostic
4972 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4973 The real bug is a race condition between Emacs and glib: Emacs
4974 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4975 so that glib can't find it. Work around the bug by invoking
4976 waitpid only on subprocesses that Emacs itself creates.
4977 * process.c (create_process, record_child_status_change):
4978 Don't use special value -1 in pid field, as the caller now must
4979 know the pid rather than having the callee infer it.
4980 The inference was sometimes incorrect anyway, due to another race.
4981 (create_process): Set new 'alive' member if child is created.
4982 (process_status_retrieved): New function.
4983 (record_child_status_change): Use it.
4984 Accept negative 1st argument, which means to wait for the
4985 processes that Emacs already knows about. Move special-case code
4986 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4987 processes that have already been waited for, by testing and
4988 clearing new 'alive' member.
4989 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4990 now does this internally.
4991 (handle_child_signal): Let record_child_status_change do all
4992 the work, since we do not want to reap all exited child processes,
4993 only the child processes that Emacs itself created.
4994 * process.h (Lisp_Process): New boolean member 'alive'.
4996 Omit duplicate definitions no longer needed with gcc -g3.
4997 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4998 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4999 Define only as macros. There's no longer any need to also define
5000 these symbols as enums or as constants, since we now assume
5001 gcc -g3 when debugging.
5003 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5005 * lisp.mk: Adjust comments to the fact that term/internal is now
5006 loaded from loadup.el.
5008 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5009 (msdos_fatal_signal): New function.
5010 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5013 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5014 for GCC versions before 4.
5015 (emacs_raise): Define to call msdos_fatal_signal.
5017 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5018 iterator when starting in the middle of a display or overlay
5021 2012-11-03 Chong Yidong <cyd@gnu.org>
5023 * process.c (wait_reading_process_output): Clean up the last
5026 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5028 * process.c (wait_reading_process_output): Avoid a race condition
5029 with SIGIO delivery (Bug#11536).
5031 2012-11-03 Chong Yidong <cyd@gnu.org>
5033 * buffer.c (cursor_type): Untabify docstring.
5035 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5037 * frame.h (struct frame): Drop can_have_scroll_bars member
5038 which is meaningless for a long time. Adjust comments.
5039 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5040 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5042 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5044 * window.c (decode_next_window_args): Update window arg after
5045 calling decode_live_window and so fix crash reported at
5046 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5047 by Juanma Barranquero <lekktu@gmail.com>.
5048 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5049 * font.c (Ffont_at): Likewise.
5051 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5053 * widget.c (resize_cb): New function.
5054 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5055 (EmacsFrameResize): Check if all is up to date before changing frame
5058 2012-11-02 Eli Zaretskii <eliz@gnu.org>
5060 Implement backtrace output for fatal errors on MS-Windows.
5061 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
5062 (BACKTRACE_LIMIT_MAX): New macro.
5063 (w32_backtrace): New function.
5064 (emacs_abort): Use w32_backtrace when the user chooses not to
5065 attach a debugger. Update the text of the abort dialog.
5067 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5069 Window-related stuff cleanup here and there.
5070 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5071 Use decode_any_window.
5072 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5073 * xdisp.c (Fformat_mode_line): Likewise.
5074 * font.c (Ffont_at): Use decode_live_window.

5077 (decode_any_window): Remove static.
5078 * window.h (decode_any_window): Add prototype.
5079 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5080 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5083 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5085 Remove pad from struct input_event.
5086 * termhooks.h (struct input_event): Remove padding field.
5088 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5089 member is never cons for a long time. Adjust comment.
5090 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5091 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5092 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5093 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5095 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5097 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5099 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5101 Fix crash when using Emacs as commit editor for git (Bug#12697).
5102 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5103 and it is configured in conf_post.h.
5104 (Fcall_process): Don't invoke both setsid and setpgid; the former
5105 is enough, if it exists.
5106 * callproc.c (Fcall_process, child_setup):
5107 * process.c (create_process): Use setpgid.
5108 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5110 * dispnew.c (init_display): Initialize the foreground group
5111 if we are running a tty display.
5112 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5113 * lisp.h (init_foreground_group): New decl.
5114 * sysdep.c (inherited_pgroup): New static var.
5115 (init_foreground_group, tcsetpgrp_without_stopping)
5116 (narrow_foreground_group, widen_foreground_group): New functions.
5117 (init_sys_modes): Narrow foreground group.
5118 (reset_sys_modes): Widen foreground group.
5120 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5122 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5124 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5126 * minibuf.c (read_minibuf): Restore current buffer since
5127 choose_minibuf_frame calling Fset_frame_selected_window may
5128 change it (Bug#12766).
5130 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5132 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5134 2012-10-30 Kenichi Handa <handa@gnu.org>
5136 * font.c (Ffont_at): If WINDOW is specified and it is not
5137 displaying the current buffer, signal an error.
5139 2012-10-29 Daniel Colascione <dancol@dancol.org>
5141 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5142 In preparation for fixing bug#12739, move these functions from
5145 * coding.h, coding.c: ... to here, and compile them only when
5146 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5147 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5149 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5151 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5152 (timer_loop, getitimer, setitimer): Use it instead of
5153 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5155 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5158 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5160 * nsterm.m (NO_APPDEFINED_DATA): New define.

5162 (last_appdefined_event): Remove.
5163 (ns_select): Initialize t from last_appdefined_event_data instead
5164 of [last_appdefined_event data1].
5165 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5166 remove last_appdefined_event (Bug#12698).
5168 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5170 * frame.c (x_set_font): Catch internal error.
5172 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5174 Avoid overflow in w32 implementation of interval timers.
5175 When possible, for ITIMER_PROF count only times the main thread
5177 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5178 'volatile ULONGLONG' types. All the other data which was
5179 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5180 (GetThreadTimes_Proc): New typedef.
5181 (w32_get_timer_time): New function, returns a suitable time value
5183 (timer_loop): Enter critical section when accessing ULONGLONG
5184 values of the itimer_data struct, as these accesses are no longer
5185 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5186 Remove unused variable.
5187 (init_timers): Initialize s_pfn_Get_Thread_Times.
5188 (start_timer_thread): Don't assign itimer->caller_thread here.
5189 (getitimer): Assign itimer->caller_thread here.
5190 (setitimer): Always call getitimer to get the value of ticks_now.
5191 (sys_spawnve): Avoid compiler warning about format mismatch.
5193 2012-10-26 Eli Zaretskii <eliz@gnu.org>
5195 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5196 mouse movement events if the menu bar is active. This avoids
5197 producing a busy "hour-glass" cursor by Windows if the mouse
5198 pointer is positioned over a tooltip shown for some menu item.
5200 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5202 Don't assume process IDs fit in int.
5203 * emacs.c (shut_down_emacs) [!DOS_NT]:
5204 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5205 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5206 Use pid_t, not int, to store process IDs, as 'int'
5207 is not wide enough on a few platforms (e.g., AIX and IRIX).
5209 2012-10-23 Kenichi Handa <handa@gnu.org>
5211 The following change is to make face-font-rescale-alist work
5212 correctly for non-ASCII fonts.
5214 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5215 (font_open_for_lface): Handle Vface_font_rescale_alist.
5217 2012-10-23 Chong Yidong <cyd@gnu.org>
5219 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5221 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

5230 2012-10-21 Glenn Morris <rgm@gnu.org>
5232 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5234 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5236 Port to OpenBSD 5.1.
5237 * frame.c (Fmouse_position, Fmouse_pixel_position):
5238 * xdisp.c (produce_stretch_glyph):
5239 Declare local vars only when they're needed.
5240 This is clearer and avoids a warning on OpenBSD about unused vars.

5242 This is safer, and avoids OpenBSD warnings about unused vars.
5243 * keyboard.c (record_menu_key): Remove unnecessary decl.
5244 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5245 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5246 as our definition clashes with OpenBSD's.
5247 * xfaces.c (load_face_colors, check_lface_attrs)
5248 (get_lface_attributes_no_remap, get_lface_attributes)
5249 (lface_fully_specified_p, x_supports_face_attributes_p)
5250 (tty_supports_face_attributes_p, face_fontset, realize_face)
5251 (realize_x_face, realize_tty_face):
5252 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5253 merely Lisp_Object *. This is more informative and avoids
5254 a warning on OpenBSD about accessing beyond an object's size.
5256 2012-10-20 Chong Yidong <cyd@gnu.org>
5258 * lread.c (Fload): Doc fix (Bug#12592).

5284 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5285 (staticpro): If we run out of staticpro slots, die with an
5286 informative error instead of just calling emacs_abort.
5288 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5290 Fix two flaws reported by Dmitry Antipov.

5547 (get_input_pending): Remove first argument, since it was always
5548 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5549 and behave as if it had that value. Return new value of
5550 input_pending. All callers changed.
5551 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5552 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5554 * keymap.c (push_key_description): Omit last arg, which was always 1.
5555 All callers changed.
5557 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

5568 initializer for PVEC_NORMAL_VECTOR.
5570 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5572 Clean out old termopts cruft.
5573 * termopts.h (flow_control, meta_key): Remove unused decls.
5574 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5575 Don't include termopts.h.
5577 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5579 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5581 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5583 * commands.h (immediate_quit): Remove duplicate decl.
5585 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5587 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5589 (nsfont_open): Remove setting of Vfonts_in_cache.
5590 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5592 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5594 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5595 match what GetLastError returns. Explain why the function is
5598 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5599 'is_tooltip_frame', to avoid confusion with its global namesake.
5601 2012-10-08 Daniel Colascione <dancol@dancol.org>
5603 * xdisp.c (start_hourglass): Call w32_note_current_window when
5604 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5605 build that caused Emacs to display the hourglass cursor forever.
5607 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5608 which is broken under remote desktop, calculate the number of
5609 colors available for a display based on the display's number of
5610 planes and number of bits per pixel per plane. (bug#10397).
5612 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5614 * nsfont.m (Vfonts_in_cache): New variable.
5615 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5616 are used. Add cached fonts to Vfonts_in_cache.
5617 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5619 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5621 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5623 (FONT_H): Define after FRAME_H.
5624 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5625 Update dependencies.
5627 * w32term.c: Remove leftover declaration of keyboard_codepage.
5629 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5631 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5632 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5633 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5634 (GLOBAL_SOURCES): Add cygw32.c.
5635 ($(BLD)/unexw32.$(O)):
5637 ($(BLD)/w32console.$(O)):
5638 ($(BLD)/w32fns.$(O)):
5639 ($(BLD)/w32heap.$(O)):
5640 ($(BLD)/w32menu.$(O)):
5641 ($(BLD)/w32proc.$(O)): Add w32common.h.
5643 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5645 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5647 2012-10-08 Daniel Colascione <dancol@dancol.org>
5649 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5650 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5651 accidental message numbering hole. Change other messages to
5654 * w32select.h (HAVE_W32SELECT): Remove.
5656 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5657 w32common.h instead of w32heap.h.
5659 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5660 (get_allocation_unit, get_processor_type, get_w32_major_version)
5661 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5662 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5663 (OS_NT, os_subtype, cache_system_info): Move declarations to
5666 * w32heap.c: Include w32common.h.
5667 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5668 (w32_minor_version, w32_build_number, w32_subtype):
5669 Remove duplicate definitions.
5671 * w32fns.c: Include w32common.h; include w32heap.h only in
5674 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5675 Use `report_file_error' instead of `error' in order to better
5676 inform users of what went wrong. Increase NTGUI_UNICODE file
5677 dialog box file name length to 32k, the maximum allowed by the NT
5680 * w32common.h: New file.
5681 (ROUND_UP, ROUND_DOWN, get_page_size)
5682 (get_allocation_unit, get_processor_type, get_w32_major_version)
5683 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5684 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5685 (OS_NT, os_subtype, cache_system_info): Move here.
5687 * unexw32.c, unexcw.c: Include w32common.h.
5689 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5690 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5691 to call syms_of_w32select.
5693 * cygw32.h: Remove obsolete EXFUN declarations.
5695 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5697 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5698 of w32inevt.o from SOME_MACHINE_OBJECTS.
5700 2012-10-08 Daniel Colascione <dancol@dancol.org>
5702 * image.c: Permanent fix for JPEG compilation issue --- limit
5703 jpeglib `boolean' redefinition to Cygwin builds.
5705 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5707 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5709 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5712 2012-10-08 Daniel Colascione <dancol@dancol.org>
5714 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5715 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5716 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5717 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5718 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5719 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5720 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5721 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5722 now a supported configuration.
5724 * Makefile.in: consolidate image variables into LIBIMAGE; add
5725 W32_OBJ and W32_LIBS. Compile new files.
5728 (_DebPrint) declare tracing facility for W32 debugging. We need
5729 to unify tracing later.
5731 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5732 unconditional use of W32 Unicode functions. Cygwin runs only on
5733 100% Unicode operating systems.
5735 * cygw32.c: New file. Define Cygwin-specific facilities.
5736 (Fcygwin_convert_path_to_windows)
5737 (Fcygwin_convert_path_from_windows): New user functions for
5738 accessing Cygwin path-munging routines.
5740 * cygw32.h: New file.
5741 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5742 UTF-16LE strings temporarily inside non-Lisp-visible string
5745 (w32_strerror): Just what it says on the tin.
5747 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5748 also run for Cygwin; both systems have the same problem with using
5749 GUI facilities in a forked child. Also call syms_of_cygw32,
5750 syms_of_w32select in correct places.
5752 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5753 needs fork-then-exec for daemon launching.
5755 * font.h: Include frame.h.
5757 * image.c: Use the image library cache machinery only when we're
5758 compiling for native WINDOWSNT; Cygwin can use shared libraries
5759 like any other Unixlike system.
5761 * keyboard.c: Clarify a comment regarding the input loop.
5763 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5764 functions directly instead of trying to detect at runtime that our
5765 host operating system supports them. We make this change for two
5766 reasons: Cygwin lacks support for the multibyte character
5767 conversion functions used by the legacy menu code, and Cygwin
5768 never needs to rely on non-Unicode APIs.
5770 * unexw32.c (hinst): Declare extern.
5772 * w32.c: Change header order;
5773 (w32_strerror): Move to w32fns.c because we need it for
5774 non-WINDOWSNT builds.
5776 * w32.h: Add #error macro to make sure we don't include w32.h for
5777 Cygwin builds. Remove w32select declarations.
5779 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5780 w32fns.c. w32console.c is WINDOWSNT-only.
5782 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5783 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5785 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5786 (w32_major_version, w32_minor_version, w32_build_number)
5787 (os_subtype, sound_type): Define here
5788 (w32_defined_color): Make color parameter const for consistency
5789 with other _defined_color functions.
5790 (w32_createwindow): Unconditionally call w32_init_class instead of
5791 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5792 through the code is complex and unnecessary because class
5793 registration is practically free.
5794 (w32_name_of_message): New EMACSDEBUG-only function.
5795 (Fset_message_beep): Move here
5796 (Fx_open_connection): Require that the display name for Windows be
5797 "w32" for consistency, emacsclient disambiguation, and maybe, one
5798 day, multi-window-system support.
5799 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5800 Cygwin files for W32 GUI facilities, since these clearly don't
5801 expect Cygwin names.
5802 (_DebPrint): Define.
5803 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5804 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5805 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5806 (w32_last_error): Remove.
5808 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5810 * w32heap.c (syspage_mask): Declare here.
5811 (cache_system_info): Remove.
5813 * w32inevt.c (faked_key): Define globally, not statically.
5814 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5815 (w32_console_toggle_lock_key): Move to w32fns.c.
5817 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5819 * w32proc.c (_DebPrint): Move to w32fns.c.
5820 * w32select.c: Include string.h, stdio.h for Cygwin.
5821 * w32select.h: New File.
5823 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5825 (w32_message_fd): New variable. Under Cygwin, holds the file
5826 descriptor the system used to tell us about pending thread
5829 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5830 that prevented compilation under non-WINDOWSNT systems.
5832 (w32_initialize): Open /dev/windows and assign it to
5833 w32_message_fd. Provide w32 feature.
5835 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5836 (WM_EMACS_INPUT_READY): add.
5837 (prepend_msg, w32_message_fd): Declare globally.
5840 (keyboard_handle): Use only when WINDOWSNT.
5841 (notify_msg_ready): New function. Posts a message to the main
5842 thread's message queue under CYGWIN, which wakes up the main
5843 thread from select(2) by making the /dev/windows file descriptor
5844 ready. Under WINDOWSNT, it sets an event the same way the old
5847 (post, prepend_msg): Actually call notify_msg_ready instead of
5848 setting the input event directly.
5850 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5852 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5853 but it still has blocs in it, don't return it to the system,
5854 instead of aborting. (Bug#12402)
5856 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5858 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5860 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5861 MAC_OS_X_VERSION_10_6.
5862 (syms_of_nsterm): Remove comment about Panther and above for
5864 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5865 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5866 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5868 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5869 MAC_OS_X_VERSION_10_4.
5871 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5872 MAC_OS_X_VERSION_10_2.
5874 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5876 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5877 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5879 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5880 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5881 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5882 Remove ns_in_resize check.
5883 (ns_clear_frame_area): Remove resize handle code.
5885 * nsfns.m (ns_in_resize): Remove.
5886 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5887 Remove ns_in_resize check.
5889 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5891 Improve sys_siglist detection.
5892 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5893 defined as a macro, as is done in Solaris.
5894 (sys_siglist_entries): New macro.
5895 (save_strsignal): Use it.
5896 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5897 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5899 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5901 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5902 fullscreen/Fullscreen.
5904 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5905 tobar_height is new.
5907 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5908 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5909 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5910 (windowDidResize:): Check for correct window if old style fullscreen.
5911 Capitalize word in comment. Remove incorrect comment.
5912 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5913 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5914 error in drawing background.
5915 (toggleFullScreen:): Remove comment. Rearrange calls.
5916 Set toolbar values to zero, save old height in tobar_height.
5917 Restore tool bar height when leaving fullscreen.
5918 (canBecomeMainWindow): New function.
5920 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5922 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5924 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5926 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5928 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5929 that time stamps of directories could also be changed.
5930 Don't request the too broad GENERIC_WRITE, only the more restrictive
5931 FILE_WRITE_ATTRIBUTES access rights.
5933 * fileio.c (Fset_file_times): Special-case ignoring errors for
5934 directories only on MSDOS, not on MS-Windows.
5936 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5938 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5940 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5942 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5943 see whether CreateFile failed.
5945 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5947 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5948 to avoid similar races.
5949 * keyboard.c (pending_signals): Now bool, not int.
5951 Port timers to OpenBSD, plus check for timer failures.
5952 OpenBSD problem reported by Han Boetes.
5953 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5955 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5956 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5957 like OpenBSD, which has timer_settime but does not declare it.
5958 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5959 whether to use itimerspec-related primitives. All uses of
5960 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5962 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5964 * profiler.c (handle_profiler_signal): Fix a malloc race
5965 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5967 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5969 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5971 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5973 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5974 consistent with the change in return value of 'safe_strsignal'.
5976 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5978 Prefer plain 'static' to 'static inline' (Bug#12541).
5979 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5980 (bidi_set_sor_type, bidi_push_embedding_level)
5981 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5982 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5983 (bidi_cache_search, bidi_cache_ensure_space)
5984 (bidi_cache_iterator_state, bidi_cache_find)
5985 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5986 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5987 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5988 Now 'static', not 'static inline'.
5990 Count overruns when profiling; change units to ns.
5991 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5992 Give extra weight to samples after overruns, to attempt to count
5993 the time more accurately.
5994 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5995 the underlying primitives nominally do ns.
5996 (Fprofiler_cpu_start): Document the change. Mention that
5997 the sampling intervals are only approximate.
5999 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6001 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
6003 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
6004 case for the special 0 coding-system.
6006 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6007 (Fmake_overlay): Remove redundant tests.
6008 (fix_start_end_in_overlays): Remove redundant recentering.
6010 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6012 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6013 Update dependencies.
6015 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6017 Fix a malloc race condition involving strsignal.
6018 A signal can arrive in the middle of a malloc, and Emacs's signal
6019 handler can invoke strsignal, which can invoke malloc, which is
6020 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6021 Fix it by altering the signal handler so that it does not invoke
6023 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6024 * process.c (status_message): Use const pointer, in case strsignal
6025 is #defined to safe_strsignal.
6026 * sysdep.c (sys_siglist, init_signals): Always define and
6027 initialize a substitute sys_siglist if the system does not define
6028 one, even if HAVE_STRSIGNAL.
6029 (safe_strsignal): Rename from strsignal. Always define,
6030 using sys_siglist. Return a const pointer.
6031 * syssignal.h (safe_strsignal): New decl.
6032 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6034 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6036 * w32proc.c (timer_loop): Fix code that waits for timer
6037 expiration, to avoid high CPU usage.
6039 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6041 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6042 (sweep_weak_table): Remove redundant prototypes.
6044 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6046 * emacs.c: Move the inclusion of TERM_HEADER after including
6047 windows.h on WINDOWSNT. This avoids compilation problems with
6050 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6052 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6053 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6054 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6055 as the previous version used 'void *'.
6057 * ralloc.c (ROUNDUP): Fix last change.
6058 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6061 * w32proc.c <disable_itimers>: New static flag.
6062 (init_timers): Initialize it to zero, after creating the critical
6063 sections used by the timer threads.
6064 (term_timers): Set to 1 before deleting the critical sections.
6065 (getitimer, setitimer): If disable_itimers is non-zero, return an
6066 error indication without doing anything. Reported by Fabrice
6067 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6068 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6070 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6073 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6074 term_ntproc after all the other bookkeeping, to get timers working
6075 as long as possible.
6077 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6079 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6080 Suggested by Juri Linkov in
6081 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6083 Prefer plain 'static' to 'static inline' (Bug#12541).
6084 With static functions, modern compilers inline pretty well by
6085 themselves; advice from programmers often hurts as much as it helps.
6086 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6087 this change shrinks the text size of the Emacs executable by 1.1%
6088 without affecting CPU significantly in my benchmark.
6089 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6169 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6171 Revert the FOLLOW-SYMLINKS change for file-attributes.
6172 Doing it right would require several changes to Tramp, and there's
6173 not enough time to get that tested before the freeze today.
6174 * dired.c (directory_files_internal, Ffile_attributes):
6177 * frame.c (x_report_frame_params): Port better to wider ints.
6178 Do not assume that EMACS_UINT is the same width as uprintmax_t,

6211 * w32.c (init_environment, get_emacs_configuration): Support AMD64
6213 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
6214 compatibility with x64.
6216 * vm-limit.c (lim_data): Now size_t.
6217 (check_memory_limits): Adjust prototypes of real_morecore and
6218 __morecore to receive argument of type ptrdiff_t. Use size_t for

6244 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
6245 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

6287 Windows-specific code to display the hourglass mouse pointer is no
6289 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
6290 to hourglass timer expiration.

6371 Profiler improvements: more-accurate timers, overflow checks.
6372 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6373 signal.h, setjmp.h. Include systime.h instead.
6374 (saturated_add): New function.
6375 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

6380 (profiler_cpu_running): Now of that enum type, not bool.
6381 All uses changed to store the new value.
6382 (handle_profiler_signal): Rename from sigprof_handler_1,
6383 for consistency with other handlers. Do not check whether
6384 cpu_log is a hash-table if garbage collecting, since it
6385 doesn't matter in that case.
6386 (deliver_profiler_signal): Rename from sigprof_handler,
6387 for consistency with other handlers.
6388 (setup_cpu_timer): New function, with much of what used to be in
6389 Fprofiler_cpu_start. Check for out-of-range argument.
6390 Prefer timer_settime if available, and prefer
6391 thread cputime clocks, then process cputime clocks, then
6392 monotonic clocks, to the old realtime clock. Use make_timeval
6393 to round more-correctly when falling back to setitimer.
6394 (Fprofiler_cpu_start): Use it.
6395 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6396 Don't assume that passing NULL as the 2nd argument of setitimer
6397 is the same as passing a pointer to all-zero storage.
6398 Ignore SIGPROF afterwards.
6399 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6400 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6401 non-fatal signal handlers. Ignore SIGPROF on startup.
6402 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6403 in profiler.c, since sysdep.c now uses it.
6405 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

6427 2012-09-28 Eli Zaretskii <eliz@gnu.org>
6429 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
6430 Qautomatic_redisplay and change the symbol name. All users changed.
6432 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
6434 * profiler.c (sigprof_handler): Fix race condition.

6440 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
6442 Check more robustly for timer_settime.
6443 * Makefile.in (LIB_TIMER_TIME): New macro.
6445 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
6446 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to

6459 * character.h (MAYBE_UNIFY_CHAR): Remove.
6460 * charset.c, charset.h (maybe_unify_char): Now static.
6461 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6462 Since this stuff is now private to charset.c, there's no need for

6494 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6496 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6498 Prefer POSIX timers if available.
6499 They avoid a race if the timer is too close to the current time.
6500 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6501 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6502 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6504 2012-09-25 Eli Zaretskii <eliz@gnu.org>

6516 [WINDOWSNT] (Vlibrary_cache): Declare.
6518 * image.c (reset_image_types): New function.
6520 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

6531 * w32proc.c (sys_signal): Handle all signals defined by the
6532 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6533 handlers for signals supported by Windows. Don't override
6534 term_ntproc as the handler for SIGABRT.
6535 (sigaction): Rewrite to call sys_signal instead of duplicating its
6537 (sys_kill): Improve commentary.
6539 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6540 consistency with a signature of a signal handler. All callers
6542 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6543 install term_ntproc as a signal handler for SIGABRT, as that
6544 should be done by the dumped Emacs.
6546 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6548 * w32select.c (term_w32select): Protect against repeated
6549 invocation by setting clipboard_owner to NULL after calling

6564 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6566 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6567 when encountering an unknown bytecode.
6569 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6571 image.c, indent.c: Use bool for booleans.
6572 * dispextern.h (struct image_type): Members valid_p, load, init
6573 now return bool, not int. All uses changed.
6574 * image.c: Omit unnecessary static decls.
6575 (x_create_bitmap_mask, x_build_heuristic_mask):
6576 Return void, not int, since callers don't care about the return value.

6607 2012-09-24 Chong Yidong <cyd@gnu.org>
6609 * chartab.c (Fset_char_table_default): Obsolete function removed.
6611 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6613 Move pid_t related decls out of lisp.h.
6614 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6615 (interruptible_wait_for_termination):
6616 Move these decls from lisp.h to syswait.h, since they use pid_t.
6617 Needed on FreeBSD; see Herbert J. Skuhra in
6618 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6619 * callproc.c: Include syswait.h.

6636 * nsmenu.m (ns_update_menubar):
6637 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6638 * xfns.c (Fx_show_tip) [USE_GTK]:
6639 Use bool for boolean.
6640 * gtkutil.c (xg_update_frame_menubar):
6641 * xmenu.c (update_frame_menubar):
6642 Return void, not int, since caller ignores return value.
6643 * gtkutil.c (xg_change_toolbar_position):
6646 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6648 * makefile.w32-in (BLOCKINPUT_H): Remove.

6665 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6667 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6668 fatal_error_backtrace.
6670 * w32proc.c (sys_kill): Undo last change: don't do anything when
6671 invoked to deliver SIGABRT to our own process. This is now
6672 handled by emacs_raise.
6674 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6676 * w32term.c (w32_read_socket): Remove leftover reference to
6677 interrupt_input_pending.
6679 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6681 Do not use SA_NODEFER.
6682 Problem reported by Dani Moncayo in
6683 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6685 * sysdep.c (emacs_abort): Do not reset signal handler.
6686 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6687 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6688 wanted even on POSIXish hosts, and it doesn't work on Windows.
6690 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6692 * xterm.c (x_term_init): Call fixup_locale before and after calling
6693 gtk_init (Bug#12392).
6695 2012-09-23 Chong Yidong <cyd@gnu.org>
6697 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6698 Vdynamic_library_alist.
6700 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6701 (Fgnutls_available_p): Caller changed.
6703 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6704 (Flibxml_parse_xml_region): Likewise.
6706 * dispextern.h (struct image_type): Remove arg from init function.
6708 * image.c (Finit_image_library, lookup_image_type)
6709 (define_image_type): Remove now-unneeded second arg.
6710 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6711 (init_tiff_functions, init_gif_functions, init_svg_functions):
6712 Arglist and w32_delayed_load calling convention changed.
6713 (gs_type): Remove init_gs_functions; there is no such function.
6714 (valid_image_p, make_image): Fix caller to lookup_image_type.
6716 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6718 Simplify and avoid signal-handling races (Bug#12471).
6720 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6721 Avoid recursive loop if there's a fatal error in the function itself.
6722 * atimer.c (pending_atimers):
6723 * blockinput.h: Don't include "atimer.h"; no longer needed.
6724 (interrupt_input_pending): Remove. All uses removed.
6725 pending_signals now counts both atimers and ordinary interrupts.
6726 This is less racy than having three separate pending-signal flags.
6727 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6729 Rename from their upper-case counterparts BLOCK_INPUT,
6730 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6731 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6732 This makes it easier to access volatile variables more accurately.
6733 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6734 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6735 that's more reliable if the code is buggy and sets
6736 interrupt_input_blocked to a negative value. All uses changed.
6737 * atimer.c (deliver_alarm_signal):
6738 Remove. No need to deliver this to the parent; any thread can
6739 handle this signal now. All uses replaced by underlying handler.
6740 * atimer.c (turn_on_atimers):
6741 * dispnew.c (handle_window_change_signal):
6742 * emacs.c (handle_danger_signal):
6743 * keyboard.c (kbd_buffer_get_event):
6744 Don't reestablish signal handler; not needed with sigaction.
6745 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6747 Rework to avoid unnecessary accesses to volatile variables.
6748 (UNBLOCK_INPUT_TO): Now a function.
6749 (totally_unblock_input, unblock_input): New decls.
6750 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6751 (init_data): Remove. Necessary stuff now done in init_signal.
6752 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6753 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6754 (fatal_error_code): Remove; no longer needed.
6755 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6756 it doesn't always backtrace. All uses changed. No need to reset
6757 signal to default, since sigaction and/or die does that for us now.
6758 Use emacs_raise (FOO), not kill (getpid (), FOO).
6759 (main): Check more-accurately whether we're dumping.
6760 Move fatal-error setup to sysdep.c
6761 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6762 * gtkutil.c (xg_get_file_name, xg_get_font):
6763 Remove no-longer-needed signal-mask manipulation.
6764 * keyboard.c, process.c (POLL_FOR_INPUT):
6765 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6766 * keyboard.c (read_avail_input): Remove.
6767 All uses replaced by gobble_input.
6768 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6769 (kbd_buffer_store_event_hold, gobble_input):
6770 (record_asynch_buffer_change) [USABLE_SIGIO]:
6771 (store_user_signal_events):
6772 No need to mess with signal mask.
6773 (gobble_input): If blocking input and there are terminals, simply
6774 set pending_signals to 1 and return. All hooks changed to not
6775 worry about whether input is blocked.
6776 (process_pending_signals): Clear pending_signals before processing
6777 them, in case a signal comes in while we're processing.
6778 By convention callers now test pending_signals before calling us.
6779 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6780 New functions, to support changes to blockinput.h.
6781 (handle_input_available_signal): Now extern.
6782 (reinvoke_input_signal): Remove. All uses replaced by
6784 (quit_count): Now volatile, since a signal handler uses it.
6785 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6786 All callers changed. Block SIGINT only if not already blocked.
6787 Clear sigmask reliably, even if Fsignal returns, which it can.
6788 Omit unnecessary accesses to volatile var.
6789 (quit_throw_to_read_char): No need to restore sigmask.
6790 * keyboard.c (gobble_input, handle_user_signal):
6791 * process.c (wait_reading_process_output):
6792 Call signal-handling code rather than killing ourselves.
6793 * lisp.h: Include <float.h>, for...
6794 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6795 (pending_signals): Now volatile.
6796 (syms_of_data): Now const if IEEE floating point.
6797 (handle_input_available_signal) [USABLE_SIGIO]:
6798 (terminate_due_to_signal, record_child_status_change): New decls.
6799 * process.c (create_process): Avoid disaster if memory is exhausted
6800 while we're processing a vfork, by tightening the critical section
6802 (send_process_frame, process_sent_to, handle_pipe_signal)
6803 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6805 (send_process): No need for setjmp/longjmp any more, since the
6806 SIGPIPE stuff is now gone. Instead, report an error if errno
6808 (record_child_status_change): Now extern. PID and W are now args.
6809 Return void, not bool. All callers changed.
6810 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6811 Remove. All uses removed. This bug should be fixed now in a
6813 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6814 and record the child status change directly. This avoids the
6815 need to futz with the signal mask.
6816 (process_fatal_action): Move here from emacs.c.
6817 (emacs_sigaction_flags): New function, containing
6818 much of what used to be in emacs_sigaction_init.
6819 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6820 caught by emacs, to make races less likely.
6821 (deliver_process_signal): Rename from handle_on_main_thread.
6823 (BACKTRACE_LIMIT_MAX): Now at top level.
6824 (thread_backtrace_buffer, threadback_backtrace_pointers):
6826 (deliver_thread_signal, deliver_fatal_thread_signal):
6827 New functions, for more-accurate delivery of thread-specific signals.
6828 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6829 (deliver_arith_signal): Handle in this thread, not
6830 in the main thread, since it's triggered by this thread.
6831 (maybe_fatal_sig): New function.
6832 (init_signals): New arg DUMPING so that we can be more accurate
6833 about whether we're dumping. Caller changed.
6834 Treat thread-specific signals differently from process-general signals.
6835 Block all signals while handling fatal error; that's safer.
6836 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6838 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6839 Ignore SIGPIPE unless batch.
6840 (emacs_backtrace): Output backtrace for the appropriate thread,
6841 which is not necessarily the main thread.
6842 * syssignal.h: Include <stdbool.h>.
6843 (emacs_raise): New macro.
6844 * xterm.c (x_connection_signal): Remove; no longer needed
6845 now that we use sigaction.
6846 (x_connection_closed): No need to mess with sigmask now.
6847 (x_initialize): No need to reset SIGPIPE handler here, since
6848 init_signals does this for us now.
6850 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6852 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6853 background rect may be larger (Bug#12245).
6855 2012-09-23 Chong Yidong <cyd@gnu.org>
6857 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6859 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6861 * .gdbinit: Just stop at fatal_error_backtrace.
6862 See Stefan Monnier's request in
6863 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6864 Remove no-longer-used query of system type.
6866 2012-09-22 Chong Yidong <cyd@gnu.org>
6868 * search.c (Freplace_match): Doc fix (Bug#12325).
6870 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6872 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6873 (Fline_end_position): Doc fix.
6875 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6877 2012-09-22 Chong Yidong <cyd@gnu.org>
6879 * dispextern.h (struct image_type): Add new slot, storing a type
6880 initialization function.
6882 * image.c (define_image_type): Call the image initializer function
6883 if it is defined. Arguments and return value changed.
6884 (valid_image_p, make_image): Callers changed.
6885 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6886 (gif_type, imagemagick_type, svg_type, gs_type):
6887 Add initialization functions.
6888 (Finit_image_library): Call lookup_image_type.
6889 (CHECK_LIB_AVAILABLE): Macro deleted.
6890 (lookup_image_type): Call define_image_type here, rather than via
6891 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6892 (syms_of_image): Move define_image_type calls for xbm_type and
6893 pbm_type to lookup_image_type.
6895 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6897 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6898 'idle_timers' from here ...
6899 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6900 lists, to avoid infloops when the timer does something stupid,
6901 like reinvoke itself with the same or smaller time-out.
6904 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6906 * window.c (Fsplit_window_internal): Handle only Qt value of
6907 Vwindow_combination_limit separately.
6908 (Qtemp_buffer_resize): New symbol.
6909 (Vwindow_combination_limit): New default value.
6912 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6914 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6915 the new overlay string. (Bug#10159)
6917 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6919 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6920 or that fprintf is async-signal-safe. POSIX doesn't require
6923 2012-09-22 Chong Yidong <cyd@gnu.org>
6925 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6928 2012-09-22 Kenichi Handa <handa@gnu.org>
6930 * composite.c (composition_reseat_it): Handle the case that a
6931 grapheme cluster is not covered by a single font (Bug#12352).
6933 2012-09-21 Chong Yidong <cyd@gnu.org>
6935 * image.c (define_image_type): Avoid adding duplicate types to
6936 image_types (Bug#12463). Suggested by Jörg Walter.
6938 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6940 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6941 (print_load_command_name): Add case LC_DATA_IN_CODE.
6942 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6944 2012-09-21 Glenn Morris <rgm@gnu.org>
6946 * eval.c (Frun_hook_with_args_until_success)
6947 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6949 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6951 * fileio.c (Ffile_selinux_context): Only call freecon when
6952 lgetfilecon succeeded.
6953 (Fset_file_selinux_context): Likewise. (Bug#12444)
6955 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6957 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6958 reordering, locate the cursor by calling set_cursor_from_row; if
6959 that fails, clear the desired glyph matrix before returning a
6960 failure indication to the caller. Fixes leaving garbled display
6961 when fast scrolling with a down-key. (Bug#12403)
6962 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6963 scrolling through multibyte text.
6965 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6967 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6968 calling mark_vectorlike since that's the one that marks the window.
6969 (mark_discard_killed_buffers): Mark the final cdr.
6970 * window.h (struct window): Move prev/next_buffers to the
6971 non-standard fields.
6972 * window.c (make_window): Initialize prev/next_buffers manually.
6974 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6976 Omit unused arg EXPECTED from socket hooks.
6977 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6978 * nsterm.m (ns_term_init):
6979 * termhooks.h (struct terminal.read_socket_hook):
6980 * w32inevt.c (w32_console_read_socket):
6981 * w32term.c (w32_read_socket):
6982 * xterm.c (XTread_socket):
6983 Omit unused arg EXPECTED. All callers changed.
6984 (store_user_signal_events): Return void, not int, since callers no
6985 longer care about the return value. All uses changed.
6987 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6989 * w32gui.h (XParseGeometry): Do not declare.
6991 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6993 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6994 Ignore 'expected'. See Eli Zaretskii in
6995 <http://bugs.gnu.org/12471#8> (last line).
6997 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6998 (XParseGeometry): Now static. Substitute extremal values for
6999 values that are out of range.
7001 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7003 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7005 * nsfns.m (XParseGeometry): Remove.
7006 (Fx_create_frame): Call x_set_offset to correctly interpret
7007 top_pos in geometry.
7009 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7010 (Fx_parse_geometry): If there is a space in string, call
7011 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7013 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7015 * search.c (scan_buffer): Use character positions in calls to
7016 region_cache_forward and region_cache_backward, not byte
7017 positions. (Bug#12196)
7019 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7020 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7022 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7023 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7024 emacs_blocked_malloc, now deleted.
7026 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7028 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7029 The workaround was for improving performance on Solaris 2.4, but
7030 is getting in the way now. Emacs will still work if someone is
7031 still running Solaris 2.4 in a museum somewhere; Sun dropped
7032 support for Solaris 2.4 in 2003.
7033 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7034 * process.c (create_process) [HAVE_WORKING_VFORK]:
7035 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7036 since Emacs no longer uses vfork on that platform.
7038 2012-09-17 Glenn Morris <rgm@gnu.org>
7040 * emacs.c: Use COPYRIGHT.
7042 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7044 Remove configure's --without-sync-input option (Bug#12450).
7045 When auditing signal-handling in preparation for cleaning it up,
7046 I found that SYNC_INPUT has race conditions and would be a real
7047 pain to fix. Since it's an undocumented and deprecated
7048 configure-time option, now seems like a good time to remove it.
7049 Also see <http://bugs.gnu.org/11080#16>.
7050 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7051 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7052 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7053 (malloc_hysteresis):
7054 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7055 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7056 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7057 (dont_register_blocks, bytes_used_when_reconsidered)
7058 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7059 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7060 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7061 Remove. All uses removed.
7062 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7063 implementation, one that depends on whether the new macro
7064 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7066 * atimer.c (run_timers, handle_alarm_signal):
7067 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7068 (handle_async_input, process_pending_signals)
7069 (handle_input_available_signal, init_keyboard):
7070 * nsterm.m (ns_read_socket):
7071 * process.c (wait_reading_process_output):
7072 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7073 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7075 * xterm.c (XTread_socket):
7077 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7078 * eval.c (handling_signal): Remove. All uses removed.
7079 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7080 All uses replaced with the SYNC_INPUT version.
7081 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7083 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7086 * font.c (Ffont_shape_gstring): Remove unused local.
7088 2012-09-16 Glenn Morris <rgm@gnu.org>
7090 * Makefile.in (clean): No longer run nextstep's clean.
7092 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7094 (ns-app): Move here from ns.mk, and simplify.
7095 (clean): Simplify nextstep entry.
7096 * ns.mk: Remove file.
7098 2012-09-17 Kenichi Handa <handa@gnu.org>
7100 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7101 not covert the last few charactes.
7103 2012-09-16 Kenichi Handa <handa@gnu.org>
7105 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7106 here, but just check the validity of glyphs in the glyph-string.
7108 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7110 * window.c (Fwindow_parameter, Fset_window_parameter):
7111 Accept any window as argument (Bug#12452).
7113 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7115 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7116 to ns_term_init to avoid memory leak.
7118 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7119 explicit retain/release.
7120 (ns_term_init): Only allow one display. Initialize outerpool and
7123 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7125 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7126 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7127 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7128 the Microsoft problem in a different way, by altering ../nt/config.nt.
7130 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7145 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7146 by lisp.h. This completes removal of setjmp.h inclusion
7147 erroneously announced in the previous commit. (Bug#12446)
7149 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7152 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7153 not defined as a macro. The latter happens on MS-Windows.
7156 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7158 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7159 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7160 Some instances of '#include <setjmp.h>' removed, if the
7161 only reason for the instance was because "lisp.h" was included.
7162 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7163 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7164 and _longjmp with the new symbols. Emacs already uses _setjmp if
7165 available, so this change affects only POSIXish hosts that have
7166 sigsetjmp but not _setjmp, such as some versions of Solaris and
7167 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7168 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7169 (png_load_body) [HAVE_PNG]:
7170 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7171 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7172 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7173 since PNG requires jmp_buf. This is the only exception to the
7174 general rule that we now use sys_setjmp and sys_longjmp.
7175 This exception is OK since this code does not change the signal
7176 mask or longjmp out of a signal handler.
7178 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7180 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7181 Include "syssignal.h", for 'main_thread'.
7183 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7185 Avoid out-of-range marker position (Bug#12426).
7186 * insdel.c (replace_range, replace_range_2):
7187 Adjust markers before overlays, as suggested by comments.
7188 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7189 Remove redundant check before calling offset_intervals.
7191 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7193 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7194 current buffer (Bug#12387).
7196 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7198 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7200 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7202 Use a more backwards-compatible timer format (Bug#12430).
7203 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7204 vector element, not from the 4th, since PSECS is now at the end.
7205 (Fcurrent_idle_time): Doc fix.
7207 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7209 Function to mark objects and remove killed buffers at once.
7210 * alloc.c (discard_killed_buffers): Rename to ...
7211 (mark_discard_killed buffers) ... new name. Add marking
7212 of remaining objects. Fix comment. Adjust users.
7213 (mark_object): Do not touch frame buffer lists here.
7214 * frame.c (delete_frame): Reset frame buffer lists here.
7216 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7218 Better workaround for GNOME bug when --enable-gcc-warnings.
7219 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7220 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7221 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7223 Simplify SIGIO usage (Bug#12408).
7224 The code that dealt with SIGIO was crufty and confusing, e.g., it
7225 played tricks like "#undef SIGIO" but these tricks were not used
7226 consistently. Simplify mostly by not #undeffing standard symbols,
7227 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7228 or not as we please) rather than "defined SIGIO" (standard symbol
7229 that we probably shouldn't #undef).
7230 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7231 Modules that need it can include it.
7232 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7233 * dispextern.h (ignore_sigio): New decl.
7234 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7235 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7236 * emacs.c (shut_down_emacs):
7237 * keyboard.c (kbd_buffer_store_event_hold):
7238 Use ignore_sigio rather than invoking 'signal' directly.
7239 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7241 (FIONREAD, SIGIO): Do not #undef.
7242 (tty_read_avail_input): Use #error rather than a syntax error.
7243 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7244 for I_PIPE, used by SETUP_SLAVE_PTY.
7245 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7246 * sysdep.c (croak): Remove; no longer needed. This bit of
7247 temporary code, with Fred N. Fish's comment that it's temporary,
7248 has been in Emacs since at least 1992!
7249 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7250 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7251 * syssignal.h (croak): Remove decl.
7252 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7253 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7254 now that we're termios-only.
7255 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7256 * term.c (dissociate_if_controlling_tty): Use #error rather than
7259 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7260 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7261 to work around GNOME bug 683906.
7262 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7263 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7264 This works around GCC bug 54561.
7266 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7268 More fixes for 'volatile' and setjmp/longjmp.
7269 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7270 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7271 (png_load_body) [HAVE_PNG]:
7272 (jpeg_load_body) [HAVE_JPEG]:
7273 New function, with most of the old parent function's body.
7274 (png_load) [HAVE_PNG]:
7275 (jpeg_load) [HAVE_JPEG]:
7276 Invoke the new function, to avoid longjmp munging our locals.
7277 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7278 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7279 longjmp is passed 2, as the C standard doesn't guarantee this.
7280 Instead, store the failure code into mgr->failure_code.
7282 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7284 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7285 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7286 (syms_of_keyboard): Remove support for unread-command-char.
7288 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7290 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7291 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7292 violation. (Bug#12426)
7294 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7296 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7298 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7300 * eval.c: Add `inhibit-debugger'.
7301 (Qinhibit_debugger): New symbol.
7302 (call_debugger): Bind it instead of Qdebug_on_error.
7303 (maybe_call_debugger): Test Vinhibit_debugger.
7304 (syms_of_eval): Define inhibit-debugger.
7305 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7306 (syms_of_xdisp): Remove inhibit-debug-on-message.
7308 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7310 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7311 If a nonvolatile local variable is written before a _longjmp to
7312 the frame containing the variable, and is read after the _longjmp,
7313 the value read is indeterminate. Some local variables of type
7314 'struct handler' and 'struct catchtag' are used in this way, so
7315 mark each of their slots as volatile if the slot can be set before
7316 _longjmp and read afterwards.
7317 * lisp.h (struct handler): var and chosen_clause are now volatile.
7318 (struct catchtag): val, next, and pdlcount are now volatile.
7320 * bidi.c (bidi_push_it, bidi_pop_it):
7321 * fns.c (copy_hash_table):
7322 * image.c (define_image_type):
7323 * keyboard.c (kbd_buffer_store_event_hold):
7324 * process.c (Fprocess_send_eof):
7325 * xfaces.c (x_create_gc) [HAVE_NS]:
7326 * xgselect.c (xg_select):
7327 Prefer assignment to memcpy when either will do.
7329 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7330 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7331 time an item is removed. No need to mark this function 'inline';
7332 the compiler knows better than we do.
7334 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7336 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7337 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7338 to change_frame_size (Bug#12388).
7339 (windowDidResize:): Pass YES to updateFrameSize.
7341 * nsterm.h: Add delay parameter to updateFrameSize.
7343 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7345 Discard killed buffers from deleted window and frame objects.
7346 This reduces an amount of references to killed buffers and
7347 helps GC to reclaim them faster.
7348 * alloc.c (discard_killed_buffers): New function.
7349 (mark_object): Use it for deleted windows and frames.
7350 (mark_object): If symbol's value is set up for a killed buffer
7351 or deleted frame, restore its global binding.
7352 * data.c (swap_in_global_binding): Add GC notice.
7353 (swap_in_symval_forwarding): Use convenient set_blv_where.
7354 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7355 * window.h: ... to here.
7357 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7359 Convenient macro to check whether the buffer is live.
7360 * buffer.h (BUFFER_LIVE_P): New macro.
7361 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7362 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7364 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7366 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7367 composition cases (Bug#12364).
7369 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7370 overhang of succeeding glyphs overlapping box cursor.
7372 * w32term.c (x_draw_glyph_string): Likewise.
7374 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7376 Simplify, document, and port floating-point (Bug#12381).
7377 The porting part of this patch fixes bugs on non-IEEE platforms
7378 with frexp, ldexp, logb.
7379 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7381 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7382 support, by removing commented-out code and briefly listing the
7383 C89 functions excluded. The commented-out stuff was confusing
7384 maintenance, e.g., we thought we needed cbrt but it was commented out.
7385 (logb): Remove decl; no longer needed.
7386 (isfinite): New macro, if not already supplied.
7387 (isnan): Don't replace any existing macro.
7388 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7389 are present on all C89 platforms.
7390 (Ffrexp): Do not special-case zero, as frexp does the right thing
7392 (Flogb): Do not use logb, as it doesn't have the desired meaning
7393 on hosts that use non-base-2 floating point. Instead, stick with
7394 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7395 frexp, to avoid getting an unspecified result.
7397 * xdisp.c (Qinhibit_debug_on_message): Now static.
7399 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7401 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7402 NSBezierPath (Bug#12131).
7404 2012-09-10 Chong Yidong <cyd@gnu.org>
7406 * fns.c (Fdelq, Fdelete): Doc fix.
7408 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7410 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7411 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7413 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7415 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7416 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7419 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7421 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7422 left fringe if the window has a left margin. This avoids leaving
7423 traces of the cursor because its leftmost pixel is not drawn over.
7425 * dispnew.c (update_window_line): When the left margin area of a
7426 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7427 that screen line. (Bug#12277)
7429 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7431 Assume C89 or later for math functions (Bug#12381).
7432 This simplifies the code, and makes it a bit smaller and faster,
7433 and (most important) makes it easier to clean up signal handling
7434 since we can stop worring about floating-point exceptions in
7435 library code. That was a problem before C89, but the problem
7436 went away many years ago on all practical Emacs targets.
7437 * data.c, image.c, lread.c, print.c:
7438 Don't include <math.h>; no longer needed.
7439 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7440 might be autoconfigured, as that never happens.
7442 * doprnt.c (DBL_MAX_10_EXP):
7443 * print.c (DBL_DIG):
7444 Remove. C89 or later always defines these.
7445 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7446 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7447 (arith_error, domain_error, domain_error2):
7448 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7449 no longer needed -- we simply return what C returns. All uses removed.
7450 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7452 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7453 Remove. All uses expanded, as these macros are no longer used
7454 more than once and are now more trouble than they're worth.
7455 (Ftan): Use tan, not sin / cos.
7456 (Flogb): Assume C89 frexp.
7457 (fmod_float): Assume C89 fmod.
7458 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7459 (init_floatfns): Remove. All uses removed.
7461 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7463 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7464 compositeToPoint for OSX < 10.6 (Bug#12390).
7466 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7468 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7469 This produces more-accurate results.
7471 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7473 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7474 changes (Bug#12088).
7476 2012-09-08 Chong Yidong <cyd@gnu.org>
7478 * syntax.c (Fstring_to_syntax): Doc fix.
7480 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7482 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7483 in the internal border.
7484 (x_set_window_size): Remove static variables and their usage.
7485 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7486 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7487 Remove fringe/internal border adjustment (Bug#11052).
7488 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7489 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7490 (ns_fix_rect_ibw): Remove.
7491 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7492 (ns_dumpglyphs_box_or_relief): Ditto.
7493 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7495 (ns_dumpglyphs_image): Ditto.
7496 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7498 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7499 their usage. Add fringe_extended_p and its use as in other terms.
7500 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7501 scroll bar was removed.
7502 (updateFrameSize): New function.
7503 (windowDidResize): Move code to updateFrameSize and call it.
7505 * nsterm.h (EmacsView): Add updateFrameSize.
7507 2012-09-07 Chong Yidong <cyd@gnu.org>
7509 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7511 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7513 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7515 More signal-handler cleanup (Bug#12327).
7516 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7517 Problem introduced when merging patches. Noted by Eli Zaretskii in
7518 <http://bugs.gnu.org/12327#67>.
7519 * floatfns.c: Comment fix.
7520 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7521 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7522 and anyway the declaration is harmless even if SIGDANGER is not defined.
7523 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7524 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7525 source files not surprisingly expected syssignal.h to define, or
7526 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7527 Include <sys/ioctl.h>, for FIONREAD.
7528 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7529 This eliminates a problem whereby other files mysteriously had
7530 to include "syssignal.h" before including "systty.h" if they
7531 wanted to use "#ifdef SIGIO".
7533 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7535 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7537 * w32.c (sigemptyset): Empty the set.
7538 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7540 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7542 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7544 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7545 (mark_object): Likewise for frame objects.
7547 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7549 * syssignal.h (handle_on_main_thread): Always declare,
7550 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7551 This ports to platforms without HAVE_PTHREAD.
7553 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7555 Signal-handler cleanup (Bug#12327).
7556 Emacs's signal handlers were written in the old 4.2BSD style with
7557 sigblock and sigmask and so forth, and this led to some
7558 inefficiencies and confusion. Rewrite these to use
7559 pthread_sigmask etc. without copying signal sets around. Also,
7560 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7561 'signal', and instead use functions that do not attempt to take
7562 over the system name space. This patch causes Emacs's text
7563 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7564 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7565 Do not include <signal.h> or "syssignal.h", as these
7566 modules do not use signals.
7567 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7568 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7569 Do not include <signal.h>, as "syssignal.h" does that for us now.
7570 * atimer.c (sigmask_atimers): New function.
7571 (block_atimers, unblock_atimers): New functions,
7572 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7574 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7575 no longer needed here.
7576 * emacs.c (main): Inspect existing signal handler with sigaction,
7577 so that there's no need to block and unblock SIGHUP.
7578 * sysdep.c (struct save_signal): New member 'action', replacing
7579 old member 'handler'.
7580 (save_signal_handlers, restore_signal_handlers):
7581 Use sigaction instead of 'signal' to save and restore.
7582 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7583 New function. All users of 'signal' modified to use set_sighandler
7584 if they're writeonly, and to use sys_signal if they're read+write.
7585 (emacs_sigaction_init, forwarded_signal): New functions.
7586 (sys_signal): Remove. All uses replaced by calls to sigaction
7587 and emacs_sigaction_init, or by direct calls to 'signal'.
7588 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7589 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7590 all uses replaced by pthread_sigmask etc. calls.
7591 * syssignal.h: Include <signal.h>.
7592 (emacs_sigaction_init, forwarded_signal): New decls.
7593 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7594 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7595 (sigmask, sys_sigmask): Remove; no longer needed.
7596 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7597 (sigblock, sigunblock, sigfree):
7598 (sigsetmask) [!defined sigsetmask]:
7599 Remove. All uses replaced by pthread_sigmask.
7600 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7601 no longer need to be replaced, and its typical old uses
7602 are now done via emacs_sigaction_init and sigaction.
7603 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7604 (sys_sigdel): Remove; unused.
7605 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7607 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7609 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7610 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7612 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7614 Explicitly mark buffer_defaults and buffer_local_symbols.
7615 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7616 mark_local_symbols here.
7617 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7618 since special buffers aren't marked here any more.
7619 (allocate_buffer): Chain new buffer with all_buffers here...
7620 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7622 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7623 (syms_of_buffer): Remove staticpro of the above.
7624 (init_buffer_once): Set names for buffer_defaults and
7625 buffer_local_symbols.
7627 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7629 Use bool for booleans in font-related modules.
7630 * font.c (font_intern_prop, font_style_to_value)
7631 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7632 (generate_otf_features, font_check_otf_features, font_check_otf)
7633 (font_match_p, font_list_entities, font_at):

7635 (fontset_find_font, Fset_fontset_font)
7636 (face_suitable_for_char_p) [0]:
7637 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7638 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7639 (m17n_flt_initialized, ftfont_shape_by_flt):

7641 * nsfont.m (nsfont_draw):
7642 * w32font.c (w32font_draw):
7643 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7644 Use bool for booleans.
7645 * font.h: Adjust to above API changes.
7646 (struct font, struct font_driver, struct font_driver_list):
7647 Use bool for booleans.
7648 (struct font): Remove useless member encoding_type.
7650 * fontset.c, xftfont.c: Omit unnecessary static decls.
7652 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7654 * alloc.c (mark_object): Revert window marking code
7655 since it's unsafe for the Fset_window_configuration.
7657 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7659 Fix race conditions with signal handlers and errno (Bug#12327).
7660 Be more systematic about preserving errno whenever a signal
7661 handler returns, even if it's not in the main thread. Do this by
7662 renaming signal handlers to distinguish between signal delivery
7663 and signal handling. All uses changed.
7664 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7665 * data.c (deliver_arith_signal): Rename from arith_error.
7666 * dispnew.c (deliver_window_change_signal): Rename from
7667 window_change_signal.
7668 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7669 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7670 * keyboard.c (deliver_input_available_signal): Rename from
7671 input_available_signal.
7672 (deliver_user_signal): Rename from handle_user_signal.
7673 (deliver_interrupt_signal): Rename from interrupt_signal.
7674 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7675 (deliver_child_signal): Rename from sigchld_handler.
7676 * atimer.c (handle_alarm_signal):
7677 * data.c (handle_arith_signal):
7678 * dispnew.c (handle_window_change_signal):
7679 * emacs.c (handle_fatal_signal, handle_danger_signal):
7680 * keyboard.c (handle_input_available_signal):
7681 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7682 * process.c (handle_pipe_signal, handle_child_signal):
7683 New functions, with the actual signal-handling code taken from the
7684 original respective signal handlers, sans the sporadic attempts to
7685 preserve errno, since that's now done by handle_on_main_thread.
7686 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7687 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7688 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7690 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7691 Move initialization of main_thread to sysdep.c's init_signals.
7692 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7693 our usage, and simplifies the mainline code.
7694 (record_child_status_change): New static function, as a helper
7695 for handle_child_signal, and with most of the old child handler's
7697 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7698 (handle_child_signal): Use the above.
7699 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7700 Moved here from emacs.c.
7701 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7702 code moved here from emacs.c's main function.
7703 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7704 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7705 This lets callers save and restore errno properly.
7707 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7709 Remove redundant or unused things here and there.
7710 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7711 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7712 * editfns.c (Fcompare_buffer_substrings): Likewise.
7713 * frame.h (struct terminal, struct font_driver_list):
7714 Remove redundant declarations.
7715 * window.h (Qleft, Qright): Likewise.
7717 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7719 Do not mark objects from deleted buffers, windows and frames.
7720 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7721 (mark_object): Likewise for windows and frames.
7723 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7725 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7726 buffer_defaults and buffer_local_symbols as valid objects.
7727 Return special value to denote them.
7729 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7731 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7732 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7733 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7734 (file_name_absolute_p, Fsubstitute_in_file_name):
7735 (check_executable, check_writable, Ffile_accessible_directory_p)

7737 (Finsert_file_contents, choose_write_coding_system)
7738 (Fwrite_region, build_annotations, a_write, e_write)
7740 * filelock.c (boot_time_initialized, get_boot_time)
7741 (get_boot_time_1, lock_file_1, within_one_second):
7742 * floatfns.c (in_float):
7743 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7744 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7745 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7746 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7747 * window.c (compare_window_configurations):
7748 Use bool for booleans.
7749 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7750 (Fdefault_file_modes): Now mode_t, not int, for modes.
7751 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7752 (internal_delete_file): Now returns void, not a (boolean) int,
7753 since nobody was looking at the return value.
7754 * lisp.h, window.h: Adjust to above API changes.
7756 * xdisp.c (set_message): Simplify and reindent last change.
7758 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7760 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7762 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7764 * eval.c (call_debugger): Make the function non-static so that we
7765 can call it from set_message.
7767 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7768 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7770 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7772 Give more-useful info on a fatal error (Bug#12328).
7773 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7774 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7775 of doing the work ourselves.
7776 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7777 do most of the work.
7778 (fatal_error_backtrace): New function, taken from the guts
7779 of the old fatal_error_signal, but with a new option to output
7781 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7782 info about the signal than just its number.
7783 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7784 * sysdep.c: Include <execinfo.h>
7785 (emacs_backtrace): New function, taken partly from the previous
7786 code of the 'die' function.
7787 (emacs_abort): Call fatal_error_backtrace rather than abort.
7789 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7791 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7792 eager (load-time) macro-expansion.
7793 * lisp.mk (lisp): Add macroexp.
7795 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7797 Simplify redefinition of 'abort' (Bug#12316).
7798 Do not try to redefine the 'abort' function. Instead, redo
7799 the code so that it calls 'emacs_abort' rather than 'abort'.
7800 This removes the need for the NO_ABORT configure-time macro
7801 and makes it easier to change the abort code to do a backtrace.
7802 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7803 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7804 Remove; sysdep.c's emacs_abort now takes its place.
7805 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7806 'abort' changed to use 'emacs_abort'.
7807 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7808 (abort) [!defined abort]: Rename to ...
7809 (emacs_abort): ... new name.
7810 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7811 the place of the old 'abort' in emacs.c.
7812 * w32.c, w32fns.c (abort): Do not #undef.
7813 * w32.c (emacs_abort): Rename from w32_abort.
7815 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7817 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7818 offsets[j].dv, since the y axis of the screen coordinates points
7819 down, while the y axis of the font definition coordinates points
7820 up. This fixes display of Arabic diacritics such as KASRA and
7821 KASRATAN. (Bug#11860)
7823 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7825 Be more systematic about _setjmp vs setjmp.
7826 * alloc.c (test_setjmp, mark_stack):
7827 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7828 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7829 (png_load, my_error_exit, jpeg_load):
7830 * process.c (send_process_trap, send_process):
7831 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7832 The underscored versions are up to 30x faster on some hosts.
7833 Formerly, the code used setjmp+longjmp sometimes and
7834 _setjmp+_longjmp at other times, with no particular reason to
7835 prefer setjmp+longjmp.
7837 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7839 Fix minor problem found by static checking.
7840 * buffer.c (Fdelete_all_overlays): Return nil.
7842 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7844 * buffer.c (Fdelete_all_overlays): New function.
7846 2012-09-03 Chong Yidong <cyd@gnu.org>

7866 EXCLUDE_SUBRS_P. All callers changed.
7867 * dispextern.h, lisp.h: Reflect above API changes.
7868 * firstfile.c (dummy): Use the address of 'main', whose signature
7869 won't change, instead of the address of 'initialize', whose
7870 signature just changed from int to bool.
7871 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7872 * msdos.c (fatal_error_in_progress): ... from here.
7873 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7875 (redisplay_internal, unwind_redisplay): Simply clear
7876 REDISPLAYING_P when unwinding, instead of saving its previous,
7877 always-false value and then restoring it.
7879 Clean up some extern decls.
7880 Mostly, this hoists extern decls out of .c files and into .h files.
7881 That way, we're more likely to catch errors if the interfaces change.
7882 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7883 declare xg_mark_data.
7884 * dispextern.h (x_frame_parm_handlers):
7886 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

7902 * xfont.c (x_clear_errors):
7903 * xterm.c (x_frame_parm_handlers):
7904 Remove now-redundant extern decls.
7905 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7906 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7908 * xfaces.c: Remove unnecessary static decls.
7909 * xterm.c (updating_frame): Remove decl of nonexistent object.
7911 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7912 when building globals.h, as the objects that are not built on
7913 this host are not needed to compile C files on this host.
7915 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7917 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7955 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7957 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

7965 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7967 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7968 more than one grapheme cluster passed to the shaper: compute the
7969 offset adjustment values separately for each cluster. (Bug#11860)
7971 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7972 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7973 about implicit conversions from integer to pointer.
7975 2012-09-01 Daniel Colascione <dancol@dancol.org>
7977 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7978 system used too early.
7980 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7982 Better seed support for (random).

8024 window-system headers.

8031 window system declarations.
8033 * frame.h: Move common functions here: set_frame_menubar,
8034 x_set_window_size, x_sync, x_get_focus_frame,
8035 x_set_mouse_position, x_set_mouse_pixel_position,
8036 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8060 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8062 Remove mark_ttys function and fix tty_display_info initialization.
8063 * lisp.h (mark_ttys): Remove prototype.
8064 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8065 to mark_ttys because all possible values of 'top_frame' slot are
8066 the frames which are reachable from Vframe_list.
8067 * term.c (mark_ttys): Remove.
8068 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8070 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

8097 * lread.c (init_lread): For out-of-tree builds, only add the
8098 source directory's site-lisp dir to the load-path if it exists,
8099 consistent with in-tree builds. (Bug#12302)
8101 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

8118 (timeout_handler:): Set timer_fired to YES.
8119 (runDialogAt:): Set timer_fired to NO.
8120 Handle click on close button as quit.
8122 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8123 Add window_closed and button_values. Add void as return value for
8124 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8125 Add process_dialog as new member.
8127 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8129 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

8232 Use bool for booleans.
8233 * dired.c (file_name_completion):

8261 * fileio.c (Finsert_file_contents):
8262 Use bool for booleans.
8263 * coding.h, lisp.h: Reflect above API changes.
8264 * coding.c: Remove unnecessary static function decls.
8265 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8266 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8267 not a boolean 'int', since callers never look at the return value.
8268 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8269 * coding.h (decoding_buffer_size, encoding_buffer_size)
8270 (emacs_mule_string_char): Remove unused extern decls.
8271 (struct iso_2022_spec, struct coding_system):

8273 (struct emacs_mule_spec): Remove unused field 'full_support'.
8274 All initializations removed.
8275 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8277 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8279 Fix spare memory change (Bug#12286).
8280 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8281 (valid_lisp_object_p): Likewise.
8283 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8285 * window.c (Fset_window_configuration): Record any window's old
8286 buffer if it's replaced (see Bug#8789). If the new current
8287 buffer doesn't appear in the selected window, go to its old
8290 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8292 Special MEM_TYPE_SPARE to denote reserved memory.
8293 * alloc.c (enum mem_type): New memory type.
8294 (refill_memory_reserve): Use new type for spare memory.
8295 This prevents live_cons_p and live_string_p from incorrect
8296 detection of uninitialized objects from spare memory as live.
8298 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8301 * Makefile.in (.PHONY): versioclean -> versionclean.
8303 Remove unused external symbols.
8304 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8305 * window.c (Qwindow_valid_p, decode_valid_window):
8306 Now static, not extern.
8307 * data.c (Qinterval): Remove; unused.
8308 (syms_of_data): Do not define 'interval'.
8309 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8310 * window.h (decode_valid_window):
8313 * character.c, charset.c, chartab.c: Use bool for booleans.
8314 * character.c (lisp_string_width, string_count_byte8)

8322 (sub_char_table_set, sub_char_table_set_range)
8323 (char_table_set_range, optimize_sub_char_table)
8324 (map_sub_char_table):
8325 Use bool for boolean.
8326 * character.c (str_to_unibyte): Omit last boolean argument; it was
8327 always 0. All callers changed.
8328 * character.h, charset.h: Adjust to match previous changes.
8329 * character.h (char_printable_p): Remove decl of nonexistent function.
8330 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8331 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8332 are all boolean, so make them single-bit bitfields.
8334 * lisp.h (ASET): Remove attempt to detect side effects.
8335 It was meant to be temporary and it often doesn't work,
8336 because when IDX has side effects the behavior of IDX==IDX
8337 is undefined. See Stefan Monnier in
8338 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8340 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8342 * lisp.h (functionp): New function (extracted from Ffunctionp).
8343 (FUNCTIONP): Use it.
8344 * eval.c (Ffunctionp): Use it.
8346 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8348 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8349 as that's faster and simpler than static storage. Don't bother
8350 with the g_main_context_query overhead if g_main_context_pending
8351 says no events are pending.
8352 (gfds, gfds_size): Remove these static vars.
8353 (xgselect_initialize): Remove; no longer needed.
8354 All uses and decls removed.
8356 * emacs.c (fatal_error_signal_hook): Remove.
8357 All uses removed. This leftover from old code was always 0.
8359 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8360 * casefiddle.c (casify_object, casify_region):
8361 * casetab.c (set_case_table):
8362 * category.c, category.h (word_boundary_p):
8363 * category.h (CHAR_HAS_CATEGORY):
8364 Use bool for booleans, instead of int.
8366 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8368 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8370 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8372 On assertion failure, print backtrace if available.
8373 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8374 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8375 * Makefile.in (LIB_EXECINFO): New macro.
8378 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8379 * bytecode.c (exec_byte_code):
8380 * callint.c (check_mark, Fcall_interactively):
8381 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8382 (getenv_internal, sync_process_alive, call_process_exited):
8383 * lisp.h (USE_SAFE_ALLOCA):
8384 Use bool for booleans, instead of int.
8385 * lisp.h, process.h: Adjust prototypes to match above changes.
8386 * callint.c (Fcall_interactively): Don't assume the mark's
8387 offset fits in 'int'.
8389 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8391 * buffer.c, buffer.h: Use bool for boolean.
8392 * buffer.c (reset_buffer_local_variables)
8393 (buffer_lisp_local_variables, Fset_buffer_modified_p)
8394 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

8396 (overlay_touches_p, overlay_strings, Foverlay_put)
8397 (report_overlay_modification, call_overlay_mod_hooks):
8398 (mmap_enlarge, mmap_set_vars):
8399 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8400 Use bool for booleans, instead of int.
8401 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8402 since the 1-or-0 return value is always ignored anyway.
8403 (mmap_initialized_p):
8404 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8405 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8407 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8409 * bidi.c: Use bool for boolean.
8410 This is a bit more readable, and makes the text segment of bidi.o
8411 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8412 Presumably it's faster too.
8413 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8415 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8416 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8417 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8418 (bidi_explicit_dir_char, bidi_level_of_next_char)
8419 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8420 Use bool for booleans, instead of int.
8421 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8422 (bidi_unshelve_cache): Adjust decls to match code.
8424 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8426 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8429 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8431 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8432 * atimer.h: Include <stdbool.h>.
8434 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8436 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8437 compile time tests instead of run time tests on systems that do
8439 (FRAME_MAC_P): Remove leftover from deleted code.
8440 * frame.c (syms_of_frame): Remove leftover from deleted code.
8442 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8444 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8446 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8448 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8449 Otherwise, the compiler complains about (A?B:C) where B is void
8450 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8451 (fontset_add): Return void, for FONTSET_ADD.
8453 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8455 * alloc.c: Use bool for booleans.
8456 (gc_in_progress, abort_on_gc)
8457 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8458 (dont_register_blocks) [GC_MALLOC_CHECK]:
8459 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8460 (check_string_bytes, make_specified_string, memory_full)
8461 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8462 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8463 (mark_stack, valid_pointer_p, make_pure_string)
8464 (Fgarbage_collect, survives_gc_p, gc_sweep):
8465 Use bool for booleans, instead of int.
8466 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8467 Remove unused local.
8468 * alloc.c (PURE_POINTER_P):
8469 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8470 * editfns.c (Fformat):
8471 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8473 * fns.c (sweep_weak_table):
8474 * lisp.h (suppress_checking, push_message, survives_gc_p)
8475 (make_pure_string, gc_in_progress, abort_on_gc):
8476 * lread.c (readchar, read1):
8477 * print.c (Fprin1_to_string):
8478 * xdisp.c (push_message):
8479 Use bool for booleans affected directly or indirectly by
8482 Make recently-introduced setters macros.
8483 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8484 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8485 (set_fontset_default, set_fontset_fallback): Rename from their
8486 upper-case counterparts, and make them functions rather than macros.
8487 This is more consistent with the other recently-introduced setters.
8488 These don't need to be inline, since they're local.
8490 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8492 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8493 the loop (Bug#12247).
8495 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8497 * lisp.h (vcopy): Use memcpy rather than our own loop.
8498 This fixes a performance regression introduced by the recent
8499 addition of vcopy. This means 'vcopy' will need to be modified
8500 for a copying collector, but that's OK. Also, tighten the
8501 checking in the assertion.
8503 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8505 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8506 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8507 non-base glyph for the width of the base character, according to
8508 what x_draw_composite_glyph_string_foreground expects.
8509 Generate WADJUST value according to composition_gstring_width's
8510 expectations, to produce correct width of the composed character.
8511 Reverse the sign of the DU offset produced by ScriptPlace.
8513 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8515 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8517 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8519 Avoid direct writes to contents member of struct Lisp_Vector.
8520 * lisp.h (vcopy): New function to copy data into vector.
8521 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8522 * fns.c (Ffillarray): Use ASET.
8523 * keyboard.c (timer_check_2): Use AREF and ASET.
8524 (append_tool_bar_item, Frecent_keys): Use vcopy.
8525 * lread.c (read_vector): Use ASET.
8526 * msdos.c (Frecent_doskeys): Use vcopy.
8527 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8528 (Finternal_merge_in_global_face): Use ASET and vcopy.
8529 * xfont.c (xfont_list_pattern): Likewise.
8531 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8533 * window.c (Fwindow_point): For the selected window always return
8534 the position of its buffer's point.
8535 (Fset_window_point): For the selected window always go in its
8536 buffer to the specified position.
8538 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8540 Setter macros for fontsets.
8541 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8542 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8543 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8546 2012-08-20 Glenn Morris <rgm@gnu.org>
8548 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8549 Don't assume that `ln -f' works.
8551 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8553 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8554 and later about non-assignments with no effect. See discussion at
8555 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8558 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8560 Inline setter functions for Lisp_Objects slots of struct specbinding.
8561 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8564 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8566 * window.c (select_window): Always make selected window's buffer
8569 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8571 Use AREF and ASET for docstrings of category tables.
8572 * category.h (CATEGORY_DOCSTRING): Use AREF.
8573 (SET_CATEGORY_DOCSTRING): Use ASET.
8574 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8576 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8578 Inline setter functions for hash table members.
8579 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8580 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8581 (set_hash_key_and_value, set_hash_index, set_hash_next)
8582 (set_hash_hash): New functions.
8583 * charset.c, fns.c: Adjust users.
8585 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8587 Inline getter and setter functions for per-buffer values.
8588 * buffer.h (per_buffer_default, set_per_buffer_default)
8589 (per_buffer_value, set_per_buffer_value): New functions.
8590 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8591 * buffer.c, data.c: Adjust users.
8593 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8595 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8597 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8599 Rely on <config.h> + <unistd.h> to declare 'environ',
8600 as gnulib does this if the system doesn't.
8601 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8602 Remove declaration. MS-Windows declares it on stdlib.h which is
8603 included by conf_post.h.
8604 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8605 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8606 * vm-limit.c: Include <unistd.h>, for 'environ'.
8608 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8609 (start_of_data): Remove decl; mem-limits.h provides it.
8611 * xdisp.c (handle_invisible_prop): Make it a bit faster
8612 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8614 2012-08-19 Chong Yidong <cyd@gnu.org>
8616 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8619 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8621 * .gdbinit: Use call instead of set when calling a function in the
8624 * data.c (set_internal): Don't use set_blv_found.
8625 (Fkill_local_variable): Likewise.
8627 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8629 * nsfont.m (ns_ascii_average_width): Ensure the string
8630 ascii_printable is initialized with a null-terminated character
8631 array. Otherwise, it can contain undesired extra characters.
8633 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8635 port new setting code to Sun C 5.8 2005/10/13
8636 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8637 Return void, not Lisp_Object. Otherwise, the compiler
8638 complains about (A?B:C) where B is void and C is Lisp_Object
8639 when compiling CHAR_TABLE_SET, due to the recent change to
8640 the API of sub_char_table_set_contents.
8642 2012-08-18 Chong Yidong <cyd@gnu.org>
8644 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8645 for the string case (Bug#3874).
8647 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8649 * buffer.h (BSET): Remove (Bug#12215).
8650 Replace all uses with calls to new setter functions.

9537 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9538 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9539 not supposed to be invoked from the garbage collector.

9541 (gc_aset): New function, which is like ASET but can be
9542 used in the garbage collector.

9581 Fix macroexp crash on Windows with debugging (Bug#12118).
9582 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when

9584 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9585 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9586 since it's used in non-static inline functions now.
9588 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9589 Don't assume buffer size fits in 'int'. Remove unused local.

9615 (INLINE_HEADER_END): New macros.
9616 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9638 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9640 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9641 This how ASET and AREF are supposed to work, and makes
9642 it easier to think about future improvements. See
9643 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9644 * charset.h (set_charset_attr): New function.

10059 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10060 enumeration constants, as PURE and HEAP are too general, and clash
10061 with other headers and sources, such as gmalloc.c and the
10062 MS-Windows system headers. All users changed.
10064 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10066 Revert last save_excursion_save and save_excursion_restore changes.
10067 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

10070 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10072 Fix recently-introduced typos in Windows port.

10075 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10077 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10079 Improve GDB symbol export (Bug#12036).
10080 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10081 arms of an 'if', not using conditional expressions; otherwise GDB
10082 complains about the types in the unevaluated arm when the argument
10083 is an integer literal.
10084 (xgetint): Simplify expression.
10085 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10086 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10087 Zaretskii in <http://bugs.gnu.org/12036#13>.
10088 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10089 needed now that we have gdb_make_enums_visible.
10090 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10091 (enum enum_USE_LSB_TAG):
10092 New enum types, packaging up enums that need to be exported to GDB.
10094 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10096 Utility function to make a list from specified amount of objects.
10097 * lisp.h (enum constype): New datatype.
10098 (listn): New prototype.
10099 * alloc.c (listn): New function.
10100 (Fmemory_use_count, syms_of_alloc): Use it.

10115 Fast save_excursion_save and save_excursion_restore.
10116 * lisp.h (struct Lisp_Excursion): New data type.
10117 (PVEC_EXCURSION): New pseudovector type.
10118 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10119 to deal with it. Adjust comments.
10120 (init_marker, attach_marker): New prototype.
10121 (unchain_marker): Adjust prototype.
10122 * marker.c (attach_marker): Change to global.
10123 (init_marker): New function.

10133 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10134 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10135 emacs.c, as this is a more-suitable home. Had this been done earlier
10136 the fix for 12036 would have avoided some of the problems noted in
10137 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10138 would have been more obvious.
10139 * emacs.c: Do not include <verify.h>; no longer needed.
10140 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

10142 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10143 Remove; now done in lisp.h.
10144 * lisp.h (PUBLISH_TO_GDB): New macro.
10145 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)

10147 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10148 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10149 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10150 not be usable in #if. This simplifies things.
10152 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10154 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10156 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10158 Simplify export of symbols to GDB (Bug#12036).
10159 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10160 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10161 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10162 Adjust to changes in lisp.h and emacs.c, by using
10163 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10164 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10165 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10166 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10167 instead of gdb_valbits.
10168 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10169 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10170 instead of gdb_array_mark_flag.
10171 (xboolvector): Get size from $->size, not $->header.size.
10172 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10173 (xreload, hook-run, hookpost-run): Remove.
10174 * emacs.c: Include <verify.h>.
10175 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10176 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10178 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10179 (gdb_USE_LSB_TAG): New enum constants.
10180 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10181 Also define these as enum constants, so they're visible to GDB.
10182 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10183 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10184 as constants, so they're visible to GDB.
10185 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10186 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10187 Now enum constants, not macros, so they're visible to GDB.
10188 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10189 more convenient now. All uses changed.
10190 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10191 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10193 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10195 Explicitly free restriction data that are not needed anymore.
10196 * editfns.c (save_restriction_restore): Free restriction data.
10198 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10200 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10201 add argument, tune behavior, and adjust all callers.
10203 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10205 Use typedef for EMACS_INT, EMACS_UINT.
10206 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10207 than macros. This simplifies debugging in the usual case, since
10208 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10209 and it allows expressions involving EMACS_INT casts.
10210 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10212 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10214 * nsterm.m (ns_read_socket): Return early if there is a modal
10215 window (Bug#12043).
10217 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10219 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10220 that FOCUS-FRAME can be omitted.
10222 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10224 Adjust buffer text indirection counters at the end of Fkill_buffer.
10225 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10226 buffer is definitely dead. This should really fix an issue reported
10227 by Christoph Scholtes again. (Bug#12007).
10228 (init_buffer_once): Initialize indirection counters of
10229 buffer_defaults and buffer_local_symbols (for sanity and safety).
10231 2012-07-24 Eli Zaretskii <eliz@gnu.org>
10233 * xdisp.c (init_iterator): Don't compute dimensions of truncation
10234 and continuation glyphs on tooltip frames, leave them at zero.
10235 Avoids continued lines in tooltips. (Bug#11832)
10237 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
10239 Simplify copy_overlay.
10240 * buffer.c (copy_overlay): Simplify. Use build_marker.

10243 2012-07-23 Eli Zaretskii <eliz@gnu.org>
10245 * print.c (print_object): Don't crash when a frame's name is nil
10246 or invalid. (Bug#12025)
10248 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10249 it signals an error when a tooltip frame is being created.
10251 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10253 Cleanup miscellaneous objects allocation and initialization.
10254 * alloc.c (allocate_misc): Change to static. Add argument to
10255 specify the subtype. Adjust comment and users.
10256 (build_overlay): New function.
10257 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10258 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
10259 (allocate_misc): Remove prototype.
10260 (build_overlay): Add prototype.
10262 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10264 Swap buffer text indirection counters in Fbuffer_swap_text.
10265 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10266 This avoids crash reported by Christoph Scholtes at
10267 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10269 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10271 * nsmenu.m (Popdown_data): New struct.
10272 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
10274 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
10275 (initWithContentRect): Make imgView and contentView non-static
10276 and autorelease them. Also autorelease img and matrix (Bug#12005).
10277 (dealloc): Remove (Bug#12005).
10279 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10281 Adjust consing_since_gc when objects are explicitly freed.
10282 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
10283 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

10286 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10288 Simplify and cleanup markers positioning code.

10290 (live_buffer, set_marker_internal): New function.
10291 (Fset_marker, set_marker_restricted): Use set_marker_internal.
10292 (set_marker_both, set_marker_restricted_both): Use live_buffer.
10294 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
10296 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
10297 as it's limited by the amount of memory, not by INT_MAX.
10299 2012-07-21 Eli Zaretskii <eliz@gnu.org>
10301 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

10306 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
10307 info.dwItemData. Fixes crashes on 64-bit Windows.
10308 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
10310 2012-07-21 Jan Djärv <jan.h.d@swipnet.se>

10318 * window.c (decode_any_window): Signal an error if the window is
10319 on a dead frame (Bug#11984).
10321 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

10347 * lisp.h (consing_since_gc, gc_relative_threshold)
10348 (memory_full_cons_threshold): Revert declaration.
10349 (maybe_gc): Remove prototype, define as inline.
10350 * alloc.c: Remove old commented-out code.
10351 (consing_since_gc, gc_relative_threshold)
10352 (memory_full_cons_threshold): Revert to global.
10353 (maybe_gc): Remove.
10355 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>
10357 Simple wrapper for make_unibyte_string, adjust font_open_by_name.

10359 * dosfns.c, fileio.c, fns.c, ftfont.c, process.c:
10360 * sysdep.c, w32fns.c, xfns.c: Use it.
10361 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
10362 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
10363 Adjust users accordingly.
10364 * font.h (font_open_by_name): Adjust prototype.
10366 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>
10368 Cleanup calls to Fgarbage_collect.

10383 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
10384 'for_each_per_buffer_object_at'.
10385 All uses changed. It's better to use upper-case for macros that
10386 cannot be implemented as functions, to give the reader a clue
10387 that they're special.
10389 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
10391 * alloc.c (Fgarbage_collect): Tweak docstring.

10843 (display_line): Fix display of continuation glyphs on GUI frames
10844 when the right fringe is turned off and variable-size fonts are
10845 used in the window. Move the code that appends a stretch glyph to
10846 produce_special_glyphs, so that it could be used for truncation
10847 and continuation glyphs alike.
10848 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
10849 glyph of a suitably computed width, to align the special glyphs at
10850 the window margin. Code moved from display_line. (Bug#11832)

11027 EMACS_TIME simplification (Bug#11875).
11028 This replaces macros (which typically do not work in GDB)
11029 with functions, typedefs and enums, making the code easier to debug.
11030 The functional style also makes code easier to read and maintain.
11031 * systime.h: Include <sys/time.h> on all hosts, not just if
11032 WINDOWSNT, since 'struct timeval' is needed in general.
11033 (EMACS_TIME): Now a typedef, not a macro.

11047 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
11048 (add_emacs_time, sub_emacs_time): New functions.
11049 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

11067 (menu_separator_name_p):
11068 * nsmenu.m (ns_update_menubar):
11069 Prefer memcmp to strncmp when either will do.
11070 * nsterm.m: Include <ftoastr.h>.
11072 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11073 Prefer snprintf to strncpy.
11074 * nsterm.m (ns_term_init):
11075 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11076 * nsterm.m (ns_term_init):
11077 Avoid the need for strncpy, by using build_string or
11078 make_unibyte_string directly. Use dtoastr, not snprintf.
11079 * process.c (Fmake_network_process): Diagnose service names that
11080 are too long, rather than silently truncating them or creating
11081 non-null-terminated names.
11082 (Fnetwork_interface_info): Likewise, for interface names.
11083 * sysdep.c (system_process_attributes) [GNU_LINUX]:
11084 Prefer sprintf to strncat.
11085 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
11086 Prefer vsnprintf to vsprintf + strncpy.

11097 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
11098 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

11116 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11117 argument, adjust users accordingly. Use build_pure_c_string where

11120 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11121 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

11153 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11154 O_RDONLY already includes it).
11156 Stop ns builds setting the EMACSLOADPATH environment variable.

11158 Now it does not set EMACSLOADPATH, just returns the load-path string.
11159 * nsterm.h: Update accordingly.
11160 * lread.c [HAVE_NS]: Include nsterm.h.
11161 (init_lread) [HAVE_NS]: Use ns_load_path.

11171 (ns_init_paths): Do not set EMACSPATH.

11231 Move marker debugging code under MARKER_DEBUG.
11232 * marker.c (MARKER_DEBUG): Move marker debugging code under
11233 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11234 for bootstrap with --enable-checking (~3x slowdown reported

11269 Fix some minor --with-ns problems found by static checking.
11270 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11271 (x_set_font) [!HAVE_X_WINDOWS]:
11272 * image.c (xpm_load_image) [HAVE_NS]:
11273 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11274 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11275 Remove unused local.
11276 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11277 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11278 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11279 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11280 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11281 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11282 Fix pointer signedness problem.
11283 * xfaces.c (FRAME_X_FONT_TABLE):
11284 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11286 2012-07-07 Glenn Morris <rgm@gnu.org>
11288 * lread.c (load_path_check): New function, split from init_lread.
11289 (init_lread): Reorganize. Motivation:
11290 If EMACSLOADPATH is set, check/warn about that rather than the
11291 defaults, which we are not going to use. Hence we can remove
11292 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11293 Don't warn if site-lisp directories are missing.
11294 If not installed, start from a blank load-path, since
11295 PATH_LOADSEARCH refers to the eventual installation directories.
11297 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11299 Support truncation and continuation glyphs on GUI frames, when
11300 fringes are disabled. (Bug#11832)
11301 * xdisp.c (init_iterator): Get dimensions of truncation and
11302 continuation glyphs even if on GUI frames.
11303 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11304 or both, are absent.
11305 (start_display, move_it_in_display_line_to): Handle the case of a
11306 GUI frame without a fringe to display continuation or truncation
11308 (insert_left_trunc_glyphs): Support GUI frames: make sure
11309 truncation glyphs overwrite enough glyphs from the current line to
11310 have sufficient space in pixels.
11311 (display_line): Support truncation and continuation glyphs on GUI
11312 frames. If some spare pixels are left on the line after inserting
11313 the truncation glyphs, fill that space with a stretch glyph of a
11314 suitably computed width.
11316 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11317 produce_glyphs, to support GUI sessions.
11319 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11321 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11323 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11325 Do not require float-time's arg to fit in time_t (Bug#11825).
11326 This works better on hosts where time_t is unsigned, and where
11327 float-time is applied to the (negative) difference between two times.
11328 * editfns.c (decode_time_components): Last arg is now double *,
11329 not int *, and means to store all the result as a double, without
11330 worrying about whether the seconds part fits in time_t.
11331 All callers changed.
11332 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11333 All callers changed.
11334 (Ffloat_time): Do not fail merely because the specified time falls
11335 outside of time_t range.
11337 2012-07-07 Glenn Morris <rgm@gnu.org>
11339 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11340 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11341 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11343 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11345 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11346 Update dependencies.
11348 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11350 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11352 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
11353 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
11354 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11355 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11356 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11357 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11359 * xfont.c (compare_font_names): Redo to omit the need for casts.
11361 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11363 * xfns.c (Fx_change_window_property): Doc fix.
11364 * w32fns.c (Fx_change_window_property): Doc fix.
11366 * w32fns.c (Fx_window_property): Accept the same arguments as the
11367 X Windows version. Doc fix.
11368 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11370 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11371 Eli Zaretskii <eliz@gnu.org>
11373 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11374 Windows-specific code from nt/config.nt moved here.
11375 Obsolete settings removed.
11377 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11379 * process.c: Avoid unnecessary calls to gettime.
11380 (wait_reading_process_output): Don't get the time of day
11381 when gobbling data immediately and not waiting, as there's no need
11382 for it in that case. This removes a FIXME.
11384 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11386 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11387 is defined (Bug#11768).
11389 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11391 Fix marker debugging code.
11392 * marker.c (byte_char_debug_check): Do not perform the check
11393 if buffer is not multibyte.
11394 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11395 Call byte_char_debug_check with correct arguments.
11397 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11399 Compile marker debugging code only if ENABLE_CHECKING is defined.
11400 * marker.c (byte_char_debug_check, count_markers):
11401 Use only if ENABLE_CHECKING is defined.
11402 (byte_debug_flag): Remove.
11403 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11404 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11406 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11408 Avoid code repetition in marker-related functions.
11409 * marker.c (attach_marker): New function.
11410 (Fset_marker, set_marker_restricted, set_marker_both)
11411 (set_marker_restricted_both): Use it.
11412 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
11413 Consistently rename charno to charpos.
11414 (marker_position): Add eassert.
11415 (marker_byte_position): Convert to eassert.
11417 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11419 Simplify list operations in unchain_overlay and unchain_marker.
11420 * buffer.c (unchain_overlay): Simplify. Add comment.
11421 * marker.c (unchain_marker): Simplify. Fix comments.
11423 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11425 Introduce fast path for the widely used marker operation.

11428 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
11429 * composite.c (autocmp_chars): Likewise.
11430 * editfns.c (buildmark): Remove.
11431 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11432 (save_restriction_save): Use build_marker.
11433 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11434 * window.c (save_window_save): Likewise.
11436 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11438 Do not use Fdelete_overlay in delete_all_overlays
11439 to avoid redundant calls to unchain_overlay.
11440 * buffer.c (drop_overlay): New function.
11441 (delete_all_overlays, Fdelete_overlay): Use it.
11442 * minibuf.c (get_minibuffer): Fix comment.
11444 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11446 Port to OpenBSD 5.1 amd64.
11447 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11448 This is needed for OpenBSD, and should be harmless on all BSD systems.
11449 Also, include <sys/sysctl.h>, as it should be available on all
11450 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11451 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11452 use p_pid member, not kp_proc.pid.
11454 2012-07-06 Glenn Morris <rgm@gnu.org>
11456 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11458 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11460 More xmalloc and related cleanup.
11461 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11462 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
11463 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

11469 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11471 Omit needless casts involving void * pointers and allocation.
11472 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11473 as the former is more robust if P's type is changed.
11474 Prefer xzalloc to xmalloc + memset 0.
11475 Simplify malloc-or-realloc to realloc.
11476 Don't worry about xmalloc returning a null pointer.
11477 Prefer xstrdup to xmalloc + strcpy.
11478 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11480 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11481 alloca of a constant.
11483 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11485 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11486 hscroll is larger than the line width. Fixes long and futile
11487 looping inside extend_face_to_end_of_line (on a TTY) producing
11488 glyphs that are not needed and thrown away.
11490 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11492 * marker.c (set_marker_restricted_both): Simplify by using
11495 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11497 * editfns.c (region_limit): Simplify by using clip_to_bounds.
11499 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
11501 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
11502 not defined (Bug#11768).
11503 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
11504 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
11505 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
11506 followed by gtk_box_set_homogeneous (Bug#11768).
11507 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11508 (update_theme_scrollbar_width, xg_create_scroll_bar):
11509 Use gtk_scrollbar_new (Bug#11768).
11510 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11511 (is_box_type): New function (Bug#11768).
11512 (xg_tool_item_stale_p): Call is_box_type.
11513 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11514 with default display (Bug#11768).
11516 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11518 * xdisp.c (window_hscroll_limited): New function.
11519 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11520 coordinates when window's hscroll is set to insanely large
11521 values. (Bug#11857)
11523 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11525 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

11584 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11586 * fileio.c (time_error_value): Check the right error number.
11587 Problem reported by Troels Nielsen in
11588 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11590 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11592 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11593 This should be fixed in a better way; see Eli Zaretskii in
11594 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11595 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11597 * fileio.c (time_error_value): Rename from special_mtime.
11598 The old name's problems were noted by Eli Zaretskii in
11599 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11601 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11602 This variable's comment says Emacs needs at least one GDB-visible
11603 symbol of type enum pvec_type, to work around GDB problems.
11604 The symbol's value doesn't matter.
11606 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11607 that causes compilation to fail on pre-C99 compilers.
11609 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11611 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11612 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11614 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11616 * buffer.c (init_buffer_once): Fix initialization of
11617 headers for buffer_defaults and buffer_local_symbols.
11618 Reported by Juanma Barranquero <lekktu@gmail.com>.
11620 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11622 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11623 * lisp.h (enum pvec_type): Use fewer bits.
11624 (PSEUDOVECTOR_SIZE_BITS): New constant.
11625 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11626 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11627 change in pvec_type.
11628 (PSEUDOVECTOR_TYPEP): New macro.
11629 (TYPED_PSEUDOVECTORP): Use it.
11630 * fns.c (internal_equal): Adapt code to extract pvectype.
11631 * emacs.c (gdb_pvec_type): Update type.
11632 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11633 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11634 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11635 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11636 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11637 abusing vector->header.next.nbytes.
11638 (live_vector_p): Use PVEC_TYPE.
11639 (mark_object): Adapt code to extract pvectype. Use switch.
11641 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11643 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11644 Tighten new eassert a bit.
11646 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11648 Fix compilation with --enable-gcc-warnings and -O1
11649 optimization level.
11650 * doprnt.c (doprnt): Change type of tem to int, initialize
11651 to avoid compiler warning. Add eassert.
11652 * search.c (simple_search): Initialize match_byte to avoid
11653 compiler warning. Add eassert.
11655 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11657 Avoid weird behavior with large horizontal scrolls.
11658 Without this change, for example, large hscroll values would
11659 mess up Emacs's display on Fedora 15 x86, presumably due to
11660 overflows in int calculations in the display code.
11661 Also, if buffers had long lines, Emacs would freeze.
11662 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11663 (set_window_hscroll): New function, containing the old guts of
11664 Fset_window_hscroll. Return the clipped value.
11665 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11666 This avoids the need to check against PTRDIFF_MAX.
11668 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11670 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11672 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11674 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11676 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11677 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11678 since GCC 4.4.6 issues a bogus warning for them.
11680 Fix bugs in file timestamp newness comparisons.
11681 * fileio.c (Ffile_newer_than_file_p):
11682 * lread.c (Fload): Use full timestamp resolution of files,
11683 not just the 1-second resolution, so that files that are only
11684 slightly newer still count as newer.
11685 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11686 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11688 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11690 * fileio.c: Improve handling of file time marker. (Bug#11852)
11691 (special_mtime): New function.
11692 (Finsert_file_contents, Fverify_visited_file_modtime):
11693 Use it to set special mtime values consistently.
11695 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11697 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11698 marker for non-existing file. (Bug#11852)
11700 2012-07-03 Glenn Morris <rgm@gnu.org>
11702 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11703 and did not make it into globals.h).
11705 2012-07-03 Tom Tromey <tromey@redhat.com>
11707 * window.c (Fset_window_margins, Fset_window_fringes)

11743 2012-07-03 Glenn Morris <rgm@gnu.org>
11745 * lisp.h (Frandom): Make it visible to C.
11746 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11747 buffer for invisible buffers. (Bug#1229)
11749 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11751 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11752 values which aren't power of 2.
11753 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11754 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11757 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11759 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11761 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11763 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11765 * alloc.c (allocate_vector_block): Remove redundant
11766 calls to mallopt if DOUG_LEA_MALLOC is defined.
11767 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11768 avoid calls to mallopt if zero_vector is returned.
11770 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11772 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11773 is enabled, avoid dereferencing NULL current_sblock if
11776 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11778 Cleanup basic buffer management.
11779 * buffer.h (struct buffer): Change layout to use generic vector
11780 marking code. Fix some comments. Change type of 'clip_changed'
11781 to bitfield. Remove unused #ifndef old.
11782 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11783 (GET_OVERLAYS_AT): Fix indentation.
11784 (for_each_per_buffer_object_at): New macro.
11785 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11786 (Fbuffer_local_variables): Use it.
11787 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11788 * alloc.c (allocate_buffer): Adjust to match new layout of
11789 struct buffer. Fix comment.
11790 (mark_overlay): New function.
11791 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11792 Lisp area of struct buffer.
11793 (mark_object): Use it. Adjust marking of misc objects
11794 and related comments.
11796 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11798 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11799 wrapper that is not needed because the wrapped code is a no-op (zero
11800 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11801 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11803 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11805 * alloc.c (mark_buffer): Simplify. Remove prototype.
11806 (mark_object): Add comment. Reorganize marking of vector-like
11807 objects. Use CHECK_LIVE for all vector-like objects except buffers
11808 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11809 Avoid redundant calls to mark_vectorlike for bool vectors.
11811 2012-06-30 Glenn Morris <rgm@gnu.org>
11813 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11815 * epaths.in (PATH_SITELOADSEARCH): New.
11816 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11817 This is rather than relying on --enable-locallisppath elements
11818 having "site-lisp" in their names. (Bug#10208#25, 11658)
11820 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11822 * w32proc.c (sys_select): Accept and ignore one more argument.
11824 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11826 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11827 (pselect) [!MS_DOS]: Redirect to sys_select.
11829 * sysdep.c: Don't include dos.h and dosfns.h.
11831 * process.c (sys_select):
11832 * msdos.c (sys_select): Accept one more argument and ignore it.
11834 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11835 adapt data types and code to that.
11838 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11839 which clashes with the gnulib function of the same name.
11841 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11843 * font.c (font_style_to_value, font_style_symbolic)
11844 (font_prop_validate_style): Add type checks for values in
11847 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11849 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11852 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11854 * xdisp.c (try_window_id): Undo last change.
11856 * w32.c (getwd): Adjust commentary about startup_dir.
11857 (init_environment): Always call sys_access, even in non-MSVC
11858 builds. Don't chdir to the directory of the Emacs executable.
11859 This undoes code from 1997 which was justified by the need to
11860 "avoid conflicts when removing and renaming directories". But its
11861 downside was that every relative file name was being interpreted
11862 relative to the directory of the Emacs executable, which can never
11863 be TRT. In particular, it broke sys_access when called with
11864 relative file names.
11865 (sys_access): Map GetLastError to errno.
11867 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11871 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11873 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11876 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11878 * gnutls.c (emacs_gnutls_handshake):
11879 Add QUIT to make the loop interruptible.
11881 2012-06-29 Glenn Morris <rgm@gnu.org>
11883 * charset.c (init_charset): Make lack of etc/charsets fatal.
11885 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11887 * editfns.c (region_limit): Fix type mismatch.
11889 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11891 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11892 undefined. Convert from xassert to eassert.
11893 * nsmenu.m: Convert from xassert to eassert.
11894 * nsterm.m: Likewise.
11896 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11898 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11900 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11902 Avoid integer overflow on scroll-left and scroll-right.
11903 * window.c (HSCROLL_MAX): New macro.
11904 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11905 overflow when requested scroll falls outside ptrdiff_t range.
11907 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11909 * window.h (struct window): Change type of 'hscroll',
11910 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11911 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11912 Adjust users accordingly.
11913 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11914 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11915 from EMACS_INT to ptrdiff_t.
11916 (make_window): Omit redundant initialization.

11935 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11936 adjust comments accordingly.

12057 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12059 Use sprintf return value instead of invoking strlen on result.
12060 In the old days this wasn't portable, since some sprintf
12061 implementations returned char *. But they died out years ago and
12062 Emacs already assumes sprintf returns int.
12063 Similarly for float_to_string.
12064 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

12070 * xdisp.c (message_dolog):
12071 * xfns.c (syms_of_xfns):
12072 Use sprintf or float_to_string result to avoid need to call strlen.
12073 * data.c (Fnumber_to_string):
12074 Use make_unibyte_string, since the string must be ASCII.
12075 * lisp.h, print.c (float_to_string): Now returns int length.
12076 * term.c (produce_glyphless_glyph):
12077 Use sprintf result rather than recomputing it.
12079 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12080 * Makefile.in (ALL_CFLAGS):
12081 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

12087 strcasecmp if available.

12108 * xfns.c (x_window): Remove redundant cast.
12110 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12112 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12113 `const char *' to `char *' to avoid compiler warning.
12115 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12117 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12118 instead of truncating it to 63 (admittedly a generous limit).
12120 * process.c: Fix spelling and caps in comments.
12122 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12124 * emacs.c (setpgrp): Remove definition, unused.

12134 (SYSTIME_H): Add nt/inc/sys/time.h.
12136 * systime.h [WINDOWSNT]: Include sys/time.h.
12138 * s/ms-w32.h (struct timespec): Definition moved from

12171 Remove unnecessary forward decls.

12175 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
12176 * lisp.h (WAIT_READING_MAX): New macro.
12177 * dispnew.c (Fsleep_for, sit_for):
12178 * keyboard.c (kbd_buffer_get_event):
12179 * process.c (Faccept_process_output):
12180 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12181 This improves on the previous patch, which introduced a bug
12182 when time_t is unsigned and as wide as intmax_t.
12183 See <http://bugs.gnu.org/9000#51>.

12201 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
12202 Privately reported by Herbert J. Skuhra.
12203 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
12205 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

12210 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
12211 last argument of make_unibyte_string.
12213 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
12214 language ID in the event parameters.
12216 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12217 event.code, not the obscure "character set ID".
12219 2012-06-23 Chong Yidong <cyd@gnu.org>
12221 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

12246 Don't assume EMACS_TIME and struct timeval are the same type.
12248 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12250 Support higher-resolution time stamps (Bug#9000).
12251 The time stamps are only nanosecond-resolution at the C level,
12252 since that's the best that any real-world system supports now.
12253 But they are picosecond-resolution at the Lisp level, as that's
12254 easy, and leaves room for future OS improvements.
12256 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12259 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12260 Don't get current time unless it's needed.
12262 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12263 now provides it if it's absent.
12264 (start_atimer): Port to higher-res time stamps.
12265 Check for time stamp overflow. Don't get current time more
12266 often than is needed.
12268 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12269 Include systime.h, not time.h.
12270 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12272 * dired.c: Include stat-time.h.
12273 (Ffile-attributes): File times now have higher resolution.
12275 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12276 (struct image): Timestamp now has higher resolution.
12278 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12279 has at least microseconds now. All uses removed.
12280 (update_frame, update_single_window, update_window, update_frame_1)
12281 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12282 (duration_to_sec_usec): Remove; no longer needed.
12284 * editfns.c (time_overflow): Now extern.
12285 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12286 (float-time, Fformat_time_string, Fcurrent_time_string)
12287 (Fcurrent_time_zone): Accept and generate higher-resolution

12290 (decode_time_components, lisp_seconds_argument): New functions.
12291 (make_time): Now static.
12292 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12293 Report an error if the time is invalid, rather than having the caller
12296 * fileio.c: Include <stat-time.h>
12297 (Fcopy_file): Copy higher-resolution time stamps.
12298 Prefer to set the time stamp via a file descriptor if that works.
12299 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12300 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12301 (Fvisited_file_modtime, Fset_visited_file_modtime):
12302 Support higher-resolution time stamps.
12304 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12306 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12308 * image.c (prepare_image_for_display, clear_image_cache)
12309 (lookup_image): Port to higer-resolution time stamps.
12311 * keyboard.c (start_polling, bind_polling_period):
12312 Check for time stamp overflow.
12313 (read_char, kbd_buffer_get_event, timer_start_idle)
12314 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12315 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12316 Port to higher-resolution time stamps. Do not assume time_t is signed.
12317 (decode_timer): New function. Timers are now vectors of length 9,
12318 not 8, to accommodate the picosecond component.
12319 (timer_check_2): Use it.
12321 * nsterm.m (select_timeout, timeval_subtract): Remove.
12322 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12323 as they're a bit more accurate and handle overflow better.
12324 (ns_select): Change prototype to be compatible with pselect.
12325 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12326 * nsterm.h (ns_select): Adjust prototype.
12328 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12329 us-resolution time stamps.
12330 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12332 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12334 * lisp.h (time_overflow): New decl.
12335 (wait_reading_process_output): First arg is now intmax_t, not int,
12336 to accommodate larger waits.
12338 * process.h (struct Lisp_Process.read_output_delay):
12339 Now counts nanoseconds, not microseconds.
12340 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12342 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12343 (wait_reading_process_output):
12344 Port to ns-resolution time stamps.
12345 (Faccept_process_output, wait_reading_process_output):
12346 Check for time stamp overflow. Do not assume time_t is signed.
12347 (select_wrapper): Remove; we now use pselect.
12348 (Fprocess_attributes): Now generates ns-resolution time stamps.
12350 * sysdep.c: Include utimens.h. Don't include utime.h
12351 or worry about struct utimbuf; gnulib does that for us now.
12352 (gettimeofday): Remove; gnulib provides a substitute.
12353 (make_timeval): New function.
12354 (set_file_times): Now sets ns-resolution time stamps.
12355 New arg FD; all uses changed.
12356 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12357 (system_process_attributes):
12358 Now returns ns-resolution time stamp. All uses changed.
12359 Check for time stamp overflow.
12361 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12362 provides a substitute now.
12364 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12365 since it guarantees struct timespec.
12366 (EMACS_TIME): Now struct timespec, so that we can support
12367 ns-resolution time stamps.
12368 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12369 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12370 (EMACS_USECS): Remove.
12371 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12372 so multiply the arg by 1000 before storing it.
12373 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12375 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12376 Port to ns-resolution time stamps.
12377 (EMACS_TIME_NEG_P): Remove; replaced by....

12380 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12381 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12382 (make_timeval, make_lisp_time, decode_time_components): New decls.
12383 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12384 that it mishandled time_t overflow. You can't compare by subtracting!
12385 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12386 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12388 * term.c: Include <sys/time.h>.
12389 (timeval_to_Time): New function, for proper overflow wraparound.
12390 (term_mouse_position, term_mouse_click): Use it.
12392 * undo.c (record_first_change): Support higher-resolution time stamps
12393 in the undo buffer.
12394 (Fprimitive_undo): Use them when restoring time stamps.
12396 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12397 (w32_get_internal_run_time):
12398 Port to higher-resolution Emacs time stamps.
12399 (ltime): Now accepts single 64-bit integer, as that's more convenient
12402 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12404 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12405 for compatibility with pselect. Support ns-resolution time stamps.
12407 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12409 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12410 Check for time stamp overflow, and support ns-resolution time stamps.
12412 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12413 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12414 (timeval_subtract): Remove; no longer needed.
12415 (XTflash, XTring_bell, x_wait_for_event):
12416 Port to ns-resolution time stamps. Don't assume time_t is signed.
12418 2012-06-22 Chong Yidong <cyd@gnu.org>

12422 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12424 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12425 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12426 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12427 staticidx goes up to 1597 out of 1600 = 0x640.)
12429 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12431 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

12442 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
12443 access to `contents' member of Lisp_Vector objects with AREF and ASET
12446 2012-06-19 Chong Yidong <cyd@gnu.org>
12448 * frame.c (delete_frame): When selecting a frame on a different
12449 text terminal, do not alter the terminal's top-frame.

12452 frame's selected window and its terminal's top-frame.
12453 (unwind_format_mode_line): Restore them.
12454 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12456 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12457 since tty frames can be explicitly named.
12458 (prepare_menu_bars): Likewise.
12460 * term.c (Ftty_top_frame): New function.
12462 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12465 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12466 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12467 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12468 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

12475 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12477 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12478 gets killed during executing of this function (Bug#11665).
12479 Try to always return Qt when the buffer has been actually killed.
12480 (Vkill_buffer_query_functions): In doc-string say that functions
12481 run by this hook should not change the current buffer.
12483 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12485 Fix recently-introduced process.c problems found by static checking.
12486 * process.c (write_queue_push, write_queue_pop, send_process):
12487 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12488 (write_queue_pop): Fix pointer signedness problem.
12489 (send_process): Remove unused local.
12491 2012-06-17 Chong Yidong <cyd@gnu.org>

12505 * lisp.h (eassert): Assume C89 or later.
12506 This removes the need for CHECK.
12507 (CHECK): Remove. Its comments about always evaluating its
12508 argument were confusing, as 'eassert' typically does not evaluate
12511 * coding.c (produce_chars): Use ptrdiff_t, not int.
12513 * xterm.c (x_draw_underwave): Check for integer overflow.
12514 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12687 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
12688 * alloc.c (make_number) [!defined make_number]:
12689 Remove, as lisp.h always defines this now.
12690 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
12691 (roundup_size): Verify that it is a power of 2.
12692 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

12696 USE_LSB_TAG now is always defined to be either 0 or 1.
12698 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
12699 code works fine either way, and efficiency is not a concern here,
12700 as the union type is for debugging, not for production.
12701 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12702 Use an inline function on all platforms when using the union type,
12703 since this is simpler and 'static inline' can be used portably
12705 (LISP_INITIALLY_ZERO): New macro.
12706 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12707 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12775 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
12776 dbus_type_is_basic if available.
12777 (xd_extract_signed, xd_extract_unsigned): Rename from
12778 extract_signed and extract_unsigned, respectively. Adapt callers.

12791 would generate the diagnostic "Making \302\247 buffer-local while
12794 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12796 * dispnew.c (showing_window_margins_p): Undo last change, which

12809 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12810 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12812 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12814 * alloc.c (allocate_vectorlike): Fix last change.
12816 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12818 Block-based vector allocation of small vectors.

12820 adjust comment accordingly.
12821 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12822 to denote vector blocks. Adjust users (live_vector_p,

12845 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12847 * doprnt.c (doprnt): Truncate multibyte char correctly.
12848 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12849 would mishandle a string argument "Xc" if X was a multibyte
12850 character of length 2: it would truncate after X's first byte
12851 rather than including all of X.
12853 2012-06-06 Chong Yidong <cyd@gnu.org>
12855 * buffer.c (word_wrap): Doc fix.

12902 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12904 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12905 Convert pctcpu and pctmem to Lisp float properly.
12906 Let the compiler fold better, as 100.0/0x8000 is exact.
12908 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12910 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12913 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12920 bitfields where appropriate, remove unused fields.
12921 * window.h (struct window): Remove unused 'last_mark_x' and
12922 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12923 change its type from Lisp_Object to bitfield.
12924 Change type of 'force_start', 'optional_new_start',
12925 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12930 Pacify gcc -Wdouble-precision when using Xaw.
12931 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12932 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12933 Use 'float' consistently, rather than 'float' in most places
12934 and 'double' in a couple of places.
12936 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12938 * xdisp.c (handle_stop): Detect whether we have overlay strings
12939 loaded by testing it->current.overlay_string_index to be
12940 non-negative, instead of checking whether n_overlay_strings is
12941 positive. (Bug#11587)
12943 2012-05-31 Chong Yidong <cyd@gnu.org>
12945 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12951 * search.c (search_buffer): Remove calls to
12952 r_alloc_inhibit_buffer_relocation, as it is now called by
12953 maybe_unify_char, which was the cause of relocation of buffer text
12956 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12958 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12959 for the duration of call to load_charset, to avoid problems with
12960 callers of maybe_unify_char that access buffer text through C
12963 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12964 decrement the inhibition flag, instead of just setting or
12967 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12969 Remove obsolete '#define static' cruft.
12970 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12971 This #undef was "temporary" in 2000; it is no longer needed
12972 now that '#define static' has gone away.
12973 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12974 (gray_bitmap_bits): Remove; no longer needed.
12975 All uses replaced with definiens.

12987 (safe_bcopy): Remove decl; no longer has that name.
12988 (main): Coalesce #if into single bit of code, for simplicity.
12989 Cast pointers to uintptr_t, since standard libraries want integers

13018 Do not create empty overlays with the evaporate property (Bug#9642).
13019 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13020 Bug#9642, but explicitly check that the buffer the overlay would
13021 be moved to is live and rearrange lines to make sure that errors
13022 will not put the overlay in an inconsistent state.
13023 (Fdelete_overlay): Cosmetics.
13025 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13027 * w32term.c (my_bring_window_to_top): New function.
13028 (x_raise_frame): Use handle returned by DeferWindowPos, which

13041 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13042 This avoids undefined behavior that might cause the eassert
13043 to not catch an out-of-range value.
13045 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13047 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

13062 Only r_alloc_inhibit_buffer_relocation needed to be added;
13063 the others were already declared.
13065 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13066 before checking whether it's out of range. Put the check inside
13068 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

13077 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13078 defined on ralloc.c.
13080 * buffer.c [REL_ALLOC]: Remove prototypes of
13081 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13082 they are now on lisp.h.
13084 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13086 * search.c (search_buffer): Use it to inhibit relocation of buffer
13087 text while re_search_2 is doing its job, because re_search_2 is
13088 passed C pointers to buffer text. (Bug#11519)
13090 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13091 Update value to 24.
13093 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13094 state after an additional call to move_it_in_display_line_to, keep
13095 the values of it->max_ascent and it->max_descent found for the
13097 (pos_visible_p): Revert the comparison against bottom_y to what it
13098 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13101 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13103 Fix coding-related core dumps with gcc -ftrapv.
13104 The code was computing A - B, where A and B are pointers, and B is
13105 random garbage. This can lead to core dumps on platforms that
13106 have special pointer registers, and it also leads to core dumps on
13107 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13108 A - B only when B is initialized properly.
13109 * coding.c (coding_set_source, coding_set_destination): Return void.
13110 (coding_change_source, coding_change_destinations): New functions,
13111 with the old behaviors of coding_set_source and coding_set_destination.
13112 All callers that need an offset changed to use these new functions.
13114 2012-05-26 Glenn Morris <rgm@gnu.org>
13116 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13118 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13120 Extend mouse support on W32 text-mode console.
13121 * xdisp.c (draw_row_with_mouse_face):
13122 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13124 * w32console.c: Include window.h.
13125 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13127 (initialize_w32_display): Initialize mouse-highlight data.
13129 * w32inevt.c: Include termchar.h and window.h.
13130 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13131 moves, call note_mouse_highlight. If help_echo changed, call
13132 gen_help_event to produce help-echo message in the echo area.
13133 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13136 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13138 * lread.c (read1): Simplify slightly to avoid an overflow warning
13139 with GCC 4.7.0 on x86-64.
13141 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13143 * bidi.c (bidi_mirror_char): Revert last change: an int is
13144 definitely wide enough here.
13146 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13148 Fix integer width and related bugs (Bug#9874).

13160 Use int, not EMACS_INT, where int is wide enough.
13161 (inhibit_garbage_collection, Fgarbage_collect):
13162 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13163 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13164 int might not be wide enough.
13165 (bidi_cache_search, bidi_cache_find, bidi_init_it)

13180 (Foverlay_recenter, last_overlay_modification_hooks_used)
13181 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13182 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13183 (validate_region): Omit unnecessary test for b <= e,
13184 since that's guaranteed by the previous test.
13185 (adjust_overlays_for_delete): Avoid pos + length overflow.
13186 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13187 (report_overlay_modification):
13188 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13189 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13190 Omit pointer cast, which isn't needed anyway, and doesn't work
13191 after the EMACS_INT -> ptrdiff_t change.
13192 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13193 * buffer.h: Adjust decls to match defn changes elsewhere.
13194 (struct buffer_text, struct buffer):

13197 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13198 not int, to avoid needless 32-bit limit on 64-bit hosts.
13199 (exec_byte_code): Use tighter memory-full test, one that checks
13200 for alloca overflow. Don't compute the address of the object just
13201 before an array, as that's not portable. Use EMACS_INT, not
13202 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13203 * callint.c (Fcall_interactively):
13204 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13205 * callproc.c (call_process_kill, Fcall_process):
13206 Don't assume pid_t fits into an Emacs fixnum.
13207 (call_process_cleanup, Fcall_process, child_setup):

13215 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13216 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13217 (casify_object): Avoid integer overflow when overallocating buffer.
13218 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13219 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13220 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13221 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13222 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13223 integers are now checked earlier. All uses replaced with XINT.
13225 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13226 For CCL_MapSingle, check that content and value are in int range.

13228 Check that Vcode_version_map_vector is a vector.
13229 (resolve_symbol_ccl_program): Check that vector header is in range.
13230 Always copy the vector, so that we can check its contents reliably
13231 now rather than having to recheck each instruction as it's being
13232 executed. Check that vector words fit in 'int'.
13233 (ccl_get_compiled_code, Fregister_ccl_program)
13234 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13235 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13236 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13237 contents are in range.
13238 (Fccl_execute_on_string): Check that status is in range.
13239 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13240 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13241 Accept and return EMACS_INT, not int, because callers can pass values
13242 out of 'int' range.

13244 (multibyte_chars_in_text, parse_str_as_multibyte)

13247 (string_escape_byte8, Fget_byte):
13248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13249 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13250 avoid mishandling large integers.
13251 * character.h: Adjust decls to match defn changes elsewhere.
13252 * charset.c (load_charset_map_from_file, find_charsets_in_text)

13257 Don't assume fixnum fits in int.

13259 Remove now-unnecessary CHECK_NATNUMs.
13260 (Fdefine_charset_internal): Check ranges here, more carefully.
13261 Don't rely on undefined behavior with signed left shift overflow.
13262 Don't assume unsigned int fits into fixnum, or that fixnum fits
13263 into unsigned int. Don't require max_code to be a valid fixnum;
13264 that's not true for gb10830 4-byte on a 32-bit host. Allow
13265 invalid_code to be a cons, for the same reason. Require code_offset
13266 to be a character. Avoid int overflow if max_char is close
13268 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13269 this is intended anyway and avoids some undefined behavior.
13270 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13271 INDEX_TO_CODE_POINT, as that's what it expects.
13272 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13273 * charset.h (DECODE_CHAR): Return int, not unsigned;
13274 this is what was intended anyway, and it avoids undefined behavior.
13275 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13276 integer-overflow issues.
13277 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13278 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13279 where the argument is EMACS_INT, and this behavior is not intended.
13280 * chartab.c (Fmake_char_table, Fset_char_table_range)
13281 (uniprop_get_decoder, uniprop_get_encoder):
13282 Don't assume fixnum fits in int.
13283 * cmds.c (move_point): New function, that does the gist of
13284 Fforward_char and Fbackward_char, but does so while checking
13285 for integer overflow more accurately.
13286 (Fforward_char, Fbackward_char): Use it.
13287 (Fforward_line, Fend_of_line, internal_self_insert)
13288 (internal_self_insert):
13289 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13290 Fix a FIXME, by checking for integer overflow when calculating
13291 target_clm and actual_clm.

13323 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13324 (consume_chars): Rewrite to not calculate an address outside buffer.
13325 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
13326 Don't access memory outside of the args array.
13327 (Fdefine_coding_system_internal): Check for charset-id overflow.
13328 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
13329 result of ENCODE_CHAR.

13348 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
13349 Do not attempt to compute the address of the object just before a

14070 2012-05-14 Glenn Morris <rgm@gnu.org>

14077 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

14080 (report_error, report_error_1, make_hdr, copy_sym)
14081 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14082 Make arguments const char *, not char *, to avoid violations of C
14083 standard and to fix some AIX warnings reported by Gilles Pion.
14085 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14087 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14088 already have overlays loaded.
14089 (handle_single_display_spec): Before returning without displaying
14090 fringe bitmap, synchronize the bidi iterator with the main display
14091 iterator, by calling iterate_out_of_display_property.
14092 (iterate_out_of_display_property): Detect buffer iteration by
14093 testing that it->string is a Lisp string.
14094 (get_next_display_element): When the current object is exhausted,
14095 and there's something on it->stack, call set_iterator_to_next to
14096 proceed with what's on the stack, instead of returning zero.
14097 (set_iterator_to_next): If called at the end of a Lisp string,
14098 proceed to consider_string_end without incrementing string
14099 position. Don't increment display vector index past the end of
14100 the display vector. (Bug#11417)
14101 (pos_visible_p): Don't report a position visible when move_it_to
14102 stopped at the last line of window, which happens to be scanned
14103 backwards by the bidi iteration. (Bug#11464)
14105 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14107 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14108 and right-margin display specs even if the spec is invalid or we
14109 are on a TTY, and thus unable to display on the fringes.
14110 That's because the text with the property will not be displayed anyway,
14111 so we need to signal to the caller that this is a "replacing"
14112 display spec. This fixes display when the spec is invalid or we
14115 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14117 * unexaix.c (make_hdr): Fix typo in prototype.
14118 This bug broke the build on AIX. Problem reported by Gilles Pion.

14133 2012-05-12 Glenn Morris <rgm@gnu.org>
14135 * Makefile.in (MKDIR_P): New, set by configure.
14136 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14138 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

14141 * dispextern.h (hourglass_started):
14142 * w32fns.c (hourglass_started):
14143 * xdisp.c (hourglass_started): Remove.
14145 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14147 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14148 Update dependencies.
14150 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14152 * xgselect.c (xg_select): Put maxfds+1 into a var.
14153 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14155 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14157 2012-05-10 Dave Abrahams <dave@boostpro.com>
14159 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14160 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14162 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14164 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14165 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14166 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14167 Initialize xd_registered_buses.
14169 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14171 Untag more efficiently if USE_LSB_TAG.
14172 This is based on a proposal by YAMAMOTO Mitsuharu in
14173 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14174 For an admittedly artificial (nth 8000 longlist) benchmark on
14175 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14176 Emacs's overall text size by 1%.
14177 * lisp.h (XUNTAG): New macro.
14178 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14179 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14180 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14181 * eval.c (Fautoload):
14182 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14183 * frame.h (XFRAME): Use XUNTAG.
14185 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14186 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14187 Remove unportable assumptions about print widths of types like
14189 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14190 intptr_t when converting between pointer and integer, to avoid GCC
14191 warnings about wrong width.
14193 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14195 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14196 stack for each reader_thread, instead of defaulting to 8MB
14197 determined by the linker. This avoids failures in creating
14198 subprocesses on Windows 7, see the discussion in this thread:
14199 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14201 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14203 Fix up display of the *Minibuf-0* buffer in the mini window.
14204 * keyboard.c (read_char): Don't clear the echo area if there's no
14206 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14207 contents of *Minibuf-0*) if there's no message displayed in its stead.
14209 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14211 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14214 2012-05-06 Chong Yidong <cyd@gnu.org>
14216 * lisp.mk (lisp): Update.
14218 2012-05-05 Jim Meyering <meyering@redhat.com>
14220 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14222 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14224 * data.c (PUT_ERROR): New macro.
14225 (syms_of_data): Use it. Add new error type `user-error'.
14226 * undo.c (user_error): New function.
14227 (Fprimitive_undo): Use it.
14228 * print.c (print_error_message): Adjust print style for `user-error'.
14229 * keyboard.c (user_error): New function.
14230 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14232 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14234 Do not limit current-time-string to years 1000..9999.
14235 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14236 (Fcurrent_time_string): Support any year that is supported by the
14237 underlying localtime representation. Don't use asctime, as it
14238 has undefined behavior for years outside the range -999..9999.
14240 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14242 Fix race conditions involving setenv, gmtime, localtime, asctime.
14243 Without this fix, interrupts could mess up code that uses these
14244 nonreentrant functions, since setting TZ invalidates existing
14245 tm_zone or tzname values, and since most of these functions return
14246 pointers to static storage.
14247 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14248 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14249 Grow the critical sections to include not just invoking
14250 localtime/gmtime, but also accessing these functions' results
14251 including their tm_zone values if any, and any related TZ setting.
14252 (format_time_string): Last arg is now struct tm *, not struct tm **,
14253 so that the struct tm is saved in the critical section.
14254 All callers changed. Simplify allocation of initial buffer, partly
14255 motivated by the fact that memory allocation needs to be outside
14256 the critical section.
14258 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14260 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14261 with RESET_INTERVAL.
14263 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14264 Remove duplicated buffer name initialization.
14266 2012-05-02 Jim Meyering <jim@meyering.net>
14268 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14270 * xfns.c (x_window): Use xstrdup (Bug#11375).
14272 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14274 * xdisp.c (pos_visible_p): If already at a newline from the
14275 display string before the 'while' loop, don't walk back the glyphs
14276 from it3.glyph_row. Solves assertion violation when the display
14277 string begins with a newline (egg.el). (Bug#11367)
14279 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14281 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14284 2012-05-01 Glenn Morris <rgm@gnu.org>
14286 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14287 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14288 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14289 All were removed before 23.1.
14291 * dispnew.c: Remove HAVE_LIBNCURSES test;
14292 it is always true on relevant platforms.
14294 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14295 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14297 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14299 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14301 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14302 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14305 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14307 Do not avoid creating empty evaporating overlays (Bug#9642).
14308 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14309 That is, do not delete an evaporating overlay if it becomes
14310 empty after its bounds are adjusted to fit within its buffer.
14311 This fix caused other problems, and I'm reverting it until we get
14312 to the bottom of them.
14314 2012-04-27 Chong Yidong <cyd@gnu.org>
14316 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14318 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14320 * xdisp.c (pos_visible_p): If the window start position is beyond
14321 ZV, start the display from buffer beginning. Prevents assertion
14322 violation in init_iterator when the minibuffer window is scrolled
14323 via the scroll bar.
14325 * window.c (window_scroll_pixel_based): Likewise.
14327 2012-04-27 Chong Yidong <cyd@gnu.org>
14329 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14331 2012-04-27 Glenn Morris <rgm@gnu.org>
14333 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14334 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14336 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14338 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14339 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14341 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14343 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14344 display element, check also the underlying string or buffer
14345 character. (Bug#11341)
14347 * w32menu.c: Include w32heap.h.
14348 (add_menu_item): If the call to AppendMenuW (via
14349 unicode_append_menu) fails, disable Unicode menus only if we are
14350 running on Windows 9X/Me.
14352 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14354 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14355 (xgetint): Add missing shift for LSB tags.
14357 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14359 * keyboard.c (read_char): Don't wipe echo area for select window
14360 events: These might get delayed via `mouse-autoselect-window'
14363 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14365 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14366 manipulation of :loaded-from data.
14368 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14370 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14371 now a cons (bug#11311).
14373 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14375 Do not create empty overlays with the evaporate property (Bug#9642).
14376 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14377 if it becomes empty after its bounds are adjusted to fit within
14378 its buffer. Without this fix, in a nonempty buffer (let ((o
14379 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14380 yields an empty overlay that has the evaporate property, which is
14381 not supposed to happen.
14383 Fix minor GTK3 problems found by static checking.
14384 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14385 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14386 (struct _EmacsFixedClass, emacs_fixed_get_type):
14387 Move decls here from emacsgtkfixed.h, since they needn't be public.
14388 (emacs_fixed_get_type): Now static.
14389 (emacs_fixed_class_init): Omit unused local.
14390 (emacs_fixed_child_type): Remove; unused.
14391 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14392 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14393 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14394 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14395 (EMACS_FIXED_GET_CLASS): Remove; unused.
14396 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14398 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14399 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14401 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14403 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14404 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14405 (__malloc_size_t, __malloc_ptrdiff_t):
14406 Remove. All uses removed, replaced by the definiens if needed,
14407 since we can assume C89 or better now.
14408 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
14409 (protect_malloc_state, align, get_contiguous_space)
14410 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

14415 (special_realloc, _realloc_internal_nolock, _realloc_internal)
14416 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14417 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14418 Define using prototypes, not old style.
14419 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14420 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14421 (align): Don't assume that signed integer overflow wraps around.
14422 Omit unused local var.
14423 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

14425 Omit no-longer-needed casts.
14426 (valloc): Use getpagesize, not __getpagesize.
14427 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14428 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14430 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14432 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14434 Move functions from C to Lisp. Make non-blocking method calls
14435 the default. Implement further D-Bus standard interfaces.

14465 (Fdbus_method_return_internal, Fdbus_method_error_internal)
14466 (Fdbus_send_signal, Fdbus_register_service)
14467 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

14480 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
14481 Do not assume ptrdiff_t is the same width as 'int'.
14483 * alloc.c: Handle unusual debugging option combinations.
14484 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14485 since the two debugging options are incompatible.
14486 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14488 (mem_init, mem_insert, mem_insert_fixup):
14489 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

14499 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14500 Use Emacs indenting style more consistently. Avoid some casts.
14501 Use 'double' consistently rather than mixing 'float' and 'double'.
14503 2012-04-21 Eduard Wiebe <usenet@pusto.de>
14505 * sysdep.c (list_system_processes, system_process_attributes):

14519 * print.c (print_preprocess): Only check print_depth if print-circle
14521 (print_object): Check for cycles even when print-circle is nil and

14539 (set_cursor_from_row): If called for a mode-line or header-line
14540 row, return zero immediately.
14541 (try_cursor_movement): If inside continuation line, don't back up
14542 farther than the first row after the header line, if any.
14543 Don't consider the header-line row as "partially visible", even if
14544 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14546 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14582 New extern decls, to avoid calling undeclared functions.
14583 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14584 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14585 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14586 (NEED_MEM_INSERT): New macro.
14587 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14588 Remove one incorrect comment and fix another.

14602 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14603 Remove decls. This fixes an "It stinks!".
14605 * alloc.c (which_symbols): Fix alignment issue / type clash.
14607 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14609 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14610 (struct Lisp_Misc_Any): Likewise.
14611 (struct Lisp_Free): Likewise.
14612 * alloc.c (union aligned_Lisp_Symbol): Define.

14622 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14623 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14624 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14625 * s/netbsd.h, s/sol2-6.h:
14626 Remove definition of GC_MARK_STACK, since the default now works.
14627 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14628 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14629 no longer the default.
14630 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14632 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14634 * lread.c (lisp_file_lexically_bound_p):
14635 Fix hang at ";-*-\n" (bug#11238).
14637 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14639 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14640 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

14651 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14653 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14655 2012-04-11 Daniel Colascione <dancol@dancol.org>
14657 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14658 against is gone. It's better to use vfork now so that when Cygwin
14659 gains a new, working vfork, we use it automatically (bug#10398).
14661 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14679 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14681 * w32.c (w32_delayed_load): Record the full path of the library
14682 being loaded (bug#10424).
14684 2012-04-09 Glenn Morris <rgm@gnu.org>
14686 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14687 not just in the obarray, before snarfing them. (Bug#11036)
14689 * Makefile.in ($(leimdir)/leim-list.el):
14690 Pass EMACS rather than BUILT_EMACS.
14692 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14694 * process.c (make_process):
14695 * process.h: Add integer `gnutls_handshakes_tried' member to

14702 (emacs_gnutls_read): Use new log functions,
14703 `gnutls_handshakes_tried' process member, and
14704 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14705 attempts per process (connection).
14707 2012-04-09 Chong Yidong <cyd@gnu.org>
14709 * eval.c (Fuser_variable_p, user_variable_p_eh)
14710 (lisp_indirect_variable): Functions deleted.
14711 (Fdefvar): Caller changed.
14713 * callint.c (Finteractive, Fcall_interactively):
14714 * minibuf.c (Fread_variable): Callers changed.
14716 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14718 * xdisp.c (set_cursor_from_row): If the display string appears in
14719 the buffer at position that is closer to point than the position
14720 after the display string, display the cursor on the first glyph of
14721 the display string. Fixes cursor display when a 'display' text
14722 property immediately follows invisible text. (Bug#11094)
14724 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14726 composite.c: use 'double' consistently
14727 * composite.c (get_composition_id): Use 'double' consistently
14728 instead of converting 'float' to 'double' and vice versa; this is
14729 easier to understand and avoids a GCC warning.
14731 2012-04-09 Glenn Morris <rgm@gnu.org>
14733 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14734 preparation for dumping it with emacs. (Bug#4789)

14755 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14756 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14757 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14758 objects, as mark_maybe_pointer will catch them otherwise.
14759 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14760 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

14769 Support building on MS-Windows with libxml2.
14771 * makefile.w32-in (OBJ2): Add xml.$(O).
14772 (GLOBAL_SOURCES): Add xml.c.
14773 ($(BLD)/xml.$(O)): New dependency list.
14775 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14776 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14777 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14778 [!WINDOWSNT]: New macros.
14779 (init_libxml2_functions, libxml2_loaded_p): New functions.
14780 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14781 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14782 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14783 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14785 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14786 Call init_libxml2_functions before calling libxml2 functions.
14787 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14789 * emacs.c: Don't include libxml/parser.h.
14790 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14791 xmlCleanupParser directly.
14793 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14795 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14797 * indent.c (Fvertical_motion): If there is a display string at
14798 point, use it.vpos to compute how many lines to backtrack after
14799 move_it_to point. (Bug#11133)
14801 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14803 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14804 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14805 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14806 macros related to unification of CJK characters. For the details,
14807 see the discussion following the message here:
14808 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14810 2012-04-04 Chong Yidong <cyd@gnu.org>
14812 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14814 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14816 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14824 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14826 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14827 position we get to after a call to move_it_to fails the
14828 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14829 only if we wind up in a string from display property. (Bug#11063)
14831 * window.c (Fdelete_other_windows_internal): Invalidate the row
14832 and column information about mouse highlight, so that redisplay
14833 restores it after reallocating the glyph matrices. (Bug#7464)
14835 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14836 string comes from a `display' text property, use the buffer
14837 position of that property as if we actually saw that position in
14839 (move_it_by_lines): Remove the assertion that
14840 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14841 violated when there's a before-string at the beginning of a line.
14844 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14846 * xdisp.c (append_space_for_newline): If the default face was

14848 (extend_face_to_end_of_line): Use the remapped default face for
14849 extending the face to the end of the line.
14850 (display_line): Call extend_face_to_end_of_line when the default
14851 face was remapped. (Bug#11068)

14873 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14874 (command_loop_1): Use it; inhibit selection update for
14875 handle-select-window too (Bug#8996).

14879 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14881 2012-03-25 Kenichi Handa <handa@m17n.org>
14883 * dispextern.h (struct glyph): Change the bit length of
14884 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14886 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14888 * s/ms-w32.h (tzname): Include time.h before redirecting to

14893 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14896 * xterm.c (XTread_socket): Only modify handling_signal if
14897 !SYNC_INPUT. (Bug#11080)
14899 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14901 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14902 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14903 when fetching a multibyte character consumes more bytes than
14904 CHAR_BYTES returns, due to unification of CJK characters in
14905 string_char. (Bug#11073)
14907 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14909 * process.c (wait_reading_process_output): Handle pty disconnect
14910 by refraining from sending oneself a SIGCHLD (bug#10933).
14912 2012-03-22 Chong Yidong <cyd@gnu.org>
14914 * dispextern.h (struct it): New member string_from_prefix_prop_p.

14943 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14944 that is not from display property, accept the row as a "cursor
14945 row" if one of the string's character has a non-nil `cursor'
14946 property. Fixes cursor positioning when there are newlines in
14947 overlay strings, e.g. in icomplete.el. (Bug#11035)
14949 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14951 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14953 2012-03-12 Chong Yidong <cyd@gnu.org>
14955 * eval.c (inhibit_lisp_code): Rename from
14956 inhibit_window_configuration_change_hook; move from window.c.
14958 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14959 * window.c (run_window_configuration_change_hook)
14960 (syms_of_window): Callers changed.
14962 2012-03-11 Chong Yidong <cyd@gnu.org>
14964 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14966 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14968 2012-03-10 Chong Yidong <cyd@gnu.org>
14970 * frame.c (other_visible_frames): Don't assume the selected frame
14971 is visible (Bug#10955).
14973 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14975 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14977 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14979 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14980 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14983 2012-03-03 Glenn Morris <rgm@gnu.org>
14985 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14987 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14990 position past the first glyph_row that ends at ZV. (Bug#10902)
14991 (redisplay_window, next_element_from_string): Fix typos in
14993 (redisplay_window): Pass to move_it_vertically the margin in
14994 pixels, not in screen lines.
14996 2012-03-02 Glenn Morris <rgm@gnu.org>
14998 * buffer.c (buffer-list-update-hook): Doc fix.
15000 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15002 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15003 push_it before setting up the iterator for the first overlay
15004 string, even if we have an empty string loaded.
15005 (next_overlay_string): If there's an empty string on the iterator
15006 stack, pop the stack. (Bug#10903)
15008 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15010 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15011 Suggested by Stefan Monnier in
15012 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15013 * alloc.c (widen_to_Lisp_Object): New static function.
15014 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15015 and widening them to Lisp_Objects. This would work even if
15016 USE_LSB_TAG is defined and wide integers are used, which might
15017 happen in a future version of Emacs.
15019 2012-02-25 Chong Yidong <cyd@gnu.org>
15021 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
15024 * xselect.c (Fx_selection_exists_p): Doc fix.

15061 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15062 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15063 It's useless in that case, and it can cause problems on hosts
15064 that allocate halves of EMACS_INT values separately.
15065 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15066 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15067 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15068 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15069 it avoids undefined behavior on hosts where shifting right by more
15070 than the word width has undefined behavior.
15072 2012-02-19 Chong Yidong <cyd@gnu.org>
15074 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15075 (Funhandled_file_name_directory, Ffile_name_as_directory)

15117 * window.c (Fdelete_window_internal): Invalidate the mouse
15118 highlight (Bug#9904).

15196 * character.c (char_width): Return EMACS_INT, not int.
15197 (char_width, c_string_width): Check for overflow when

15224 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

15231 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15232 first 2 arguments are identical. This makes inserting large
15233 output from a subprocess an order of magnitude faster on

15687 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15688 verifies glyph row's hash code--we have just reallocated the

15854 is set, removing the need for VIRT_ADDRESS_VARIES.
15855 (PURE_P): Use a more-efficient implementation that needs just one

15872 behave as if the cursor position were at the window margin.
15874 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15875 and the cursor position is out of bounds, behave as if the cursor
15876 position were at the window margin. (Bug#10075)
15878 2011-11-18 Chong Yidong <cyd@gnu.org>
15880 * window.c (Fwindow_combination_limit): Make first argument

15902 compute_line_metrics.
15903 (compute_line_metrics): Call row_hash, instead of computing the
15906 * dispnew.c (verify_row_hash): Call row_hash for computing the
15907 hash code of a row, instead of duplicating code from xdisp.c.
15909 * dispextern.h (row_hash): Add prototype.
15911 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15913 * frame.c (delete_frame): Don't delete the terminal when the last

15967 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15968 current_matrix and desired_matrix. (Bug#9990)
15969 (verify_row_hash) [XASSERTS]: New function.

16014 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
16016 Avoid some portability problems by eschewing 'extern inline' functions.
16017 The trivial performance wins aren't worth the portability hassles; see
16018 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
16020 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

16068 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
16069 This is also needed for porting to any host where GC_MARK_STACK is
16070 not GC_MAKE_GCPROS_NOOPS.
16071 (which_symbols): Use it.

16086 * xmenu.c (cleanup_widget_value_tree): New function.
16087 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
16088 calling free_menubar_widget_value_tree directly (Bug#9830).

16094 (window_box_width, window_box_left, window_box_left_offset)
16095 (window_box_right, window_box_right_offset): Declare extern.
16096 Otherwise, these inline functions do not conform to C99 and
16097 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16098 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16099 * intervals.c (adjust_intervals_for_insertion)

16102 (static_offset_intervals): Remove.
16103 (offset_intervals): Rewrite using the old contents of
16104 static_offset_intervals. The old version didn't conform to C99
16105 because an extern inline function contained a reference to an
16106 identifier with static linkage.

16128 (Fwindow_vscroll): Doc fix.

16172 official. Move initialization of image_cache_refcount and
16173 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

16341 (w32font_open_internal, compute_metrics):
16342 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16343 instead of calling the "wide" APIs directly.

16418 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16419 * editfns.c: Rewrite current-time-zone so that it invokes
16420 the equivalent of (format-time-string "%Z") to get the time zone name.
16421 This fixes a bug when the time zone name contains characters that
16422 need converting from the system time locale to Emacs internal format.
16423 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16424 that patch fixed format-time-string to do the conversion, but
16425 I forgot to fix current-time-zone.
16426 (format_time_string): New function, containing most of
16427 what Fformat_time_string used to contain.
16428 (Fformat_time_string): Rewrite in terms of format_time_string.
16429 This doesn't change this function's behavior.
16430 (current-time-zone): Rewrite to use format_time_string.
16431 This fixes the bug reported by Michael Schierl in
16432 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16433 Jason Rumney's 2007-06-07 change worked around this bug, but
16435 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16437 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16439 * xdisp.c (start_display): If the character at POS is displayed
16440 via a display vector, reset IT->current.dpvec_index to zero.
16441 (try_window_reusing_current_matrix): If a line ends in a display
16442 vector or the next line starts in a display vector, continue
16443 redrawing the window even though the character position of
16444 start_row was reached.
16447 2011-10-18 Chong Yidong <cyd@gnu.org>
16449 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16450 with nobreak-char-display too.
16452 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16454 Fix part 3 of bug#9771.
16455 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16456 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16457 non-neutral characters if the current character is a paragraph
16458 separator (a.k.a. Newline). This avoids running the same
16459 expensive loop twice, once when we consume the preceding newline
16460 and the other time when the line actually needs to be displayed.
16461 Avoid the loop when we see neutrals on the base embedding level
16462 following a character whose directionality is the same as the
16463 paragraph's. This avoids running the expensive loop when a line
16464 ends in a long sequence of neutrals, like control characters.
16465 Add assertion against STRONG_AL type. Slightly rearrange code
16466 that determines the type of a neutral given the first non-neutral
16468 (bidi_level_of_next_char): Set next_en_pos to zero when
16469 invalidating its info.
16471 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16473 * xdisp.c (push_display_prop): Determine whether to record string
16474 or buffer position by IT->string, not by IT->method. Allow
16475 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16476 (move_it_vertically_backward): Don't look for character position
16477 immediately after the newline when in a continuation line.
16480 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16482 * window.c (coordinates_in_window): Rewrite and delabelize
16483 vertical border check. (Bug#5357) (Bug#9618)
16485 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16487 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16488 errors in XSetWindowBorder (bug#9310).
16490 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16492 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16493 avoid crash when xmalloc overrun checking is enabled.
16495 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16497 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16498 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16499 cursor motion with <left> and <right> arrow keys.
16501 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16502 some callers set that themselves.
16504 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16506 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16507 display string and the previous row comes from the same string and
16508 is empty. (Bug#9739) (Bug#9738)
16510 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16512 * doc.c (get_doc_string): Encode file name (bug#9735).
16514 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16516 * bidi.c (bidi_level_of_next_char):
16517 * xdisp.c (get_visually_first_element): Remove old incorrect
16518 comments regarding the Unicode Line Separator character.
16520 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16522 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16524 * alloc.c (Fgc_status): Do not access beyond zombies array
16525 boundary if nzombies > MAX_ZOMBIES.
16526 * alloc.c (dump_zombies): Add missing format specifier.
16528 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16530 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16531 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16533 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16534 Some packages use them to denote characters with modifiers.
16536 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16538 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16539 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16540 matching a pp-number. Rename parameter var to var1.
16542 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16544 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16546 2011-10-08 Glenn Morris <rgm@gnu.org>
16548 * callint.c (Fcall_interactively): Give a more explicit error for the
16549 'c' case with a non-character input. (Bug#8479)
16551 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16553 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16555 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16556 lines that are hscrolled on the left.
16558 * dispnew.c (buffer_posn_from_coords): Account for a possible
16559 presence of header-line. (Bug#4426)
16561 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16563 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16564 Don't advertise functionality which we discourage or doesn't work.
16566 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16568 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16569 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16570 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16571 this makes Emacs dump core during garbage collection on rare
16572 occasions. sizeof is obviously inferior to offsetof here, so
16573 stick with offsetof.
16574 (GC_POINTER_ALIGNMENT): New macro.
16575 (mark_memory): Omit 3rd (offset) arg; caller changed.
16576 Don't assume EMACS_INT alignment is the same as pointer alignment.
16578 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16580 * keyboard.c (read_key_sequence_remapped): New var.
16581 (read_key_sequence): Compute remapping in the right buffer.
16582 (command_loop_1): Use read_key_sequence's remapping directly.
16584 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16586 * dired.c (file_name_completion): Don't expand file name.
16587 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16588 before checking file name handler.
16590 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16591 they've been requested explicitly (bug#9591).
16593 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16595 * keymap.c (Fsingle_key_description): Use make_specified_string
16596 instead of build_string to build string from push_key_description.
16599 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16601 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16602 This fixes a Y2038 bug on 64-bit hosts.
16603 * buffer.c (reset_buffer):
16604 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16605 (Fclear_buffer_auto_save_failure):
16606 Use 0, not -1, to represent an unset failure time, since time_t
16607 might not be signed.
16609 Remove dependency on glibc malloc internals.
16610 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16611 Move back here from lisp.h, but with their new implementations.
16612 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16613 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16614 * charset.c (charset_table_init): New static var.
16615 (syms_of_charset): Use it instead of xmalloc. This removes a
16616 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16617 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16618 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16619 Move back to alloc.c.
16620 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16621 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16623 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16625 * nsterm.m (windowDidResize): Call x_set_window_size only when
16626 ns_in_resize is true. Otherwise set pixelwidth/height and
16627 call change_frame_size (Bug#9628).
16629 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16631 Port --enable-checking=all to Fedora 14 x86-64.
16632 * charset.c (syms_of_charset): Also account for glibc malloc's
16633 internal overhead when calculating the initial malloc maximum.
16635 Port --enable-checking=all to Fedora 14 x86.
16636 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16638 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16639 (overrun_check_realloc, overrun_check_free):
16640 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16641 That way, xmalloc returns a properly-aligned pointer even if
16642 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16643 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16644 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16645 into account when calculating the initial malloc maximum.
16646 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16647 Move here from alloc.c, so that charset.c can use it too.
16648 Properly align; the old code wasn't right for common 32-bit hosts
16649 when configured with --enable-checking=all.
16650 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16651 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16653 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16655 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16658 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16660 * xdisp.c (compute_display_string_end): If there's no display
16661 string at CHARPOS, return -1.
16663 * bidi.c (bidi_fetch_char): When compute_display_string_end
16664 returns a negative value, treat the character as a normal
16665 character not covered by a display string. (Bug#9624)
16667 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16669 * lread.c (Fread_from_string): Fix typo in docstring.
16671 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16673 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16674 newline, reseat the iterator instead of bidi-iterating there one
16675 character at a time. (Bug#9610)
16676 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16677 TO_CHARPOS if the bidi iterator is at base embedding level.
16679 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16681 * lread.c (readevalloop): Use correct code for NBSP.
16682 (read1): Likewise. (Bug#9608)
16684 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16686 * dbusbind.c (Fdbus_register_signal): When service is not
16687 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16689 2011-09-25 Glenn Morris <rgm@gnu.org>
16691 * buffer.c (truncate-lines): Doc fix.
16693 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16695 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16696 (Fset_window_next_buffers): Doc fix.
16698 2011-09-24 Glenn Morris <rgm@gnu.org>
16700 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16702 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16704 Fix minor problems found by static checking.
16705 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16706 * indent.c (Fvertical_motion): Fix == vs = typo.
16708 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16710 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16711 Default value is now t. Doc fix.
16713 * indent.c (Fvertical_motion): Compute and apply the overshoot
16714 logic when moving up, not only when moving down. Fix the
16715 confusing name and values of the it_overshoot_expected variable;
16716 logic changes accordingly. (Bug#9254) (Bug#9549)
16718 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16719 CHARPOS is covered by a display string which includes newlines.
16720 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16721 is covered by a display string with embedded newlines.
16723 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16725 * dbusbind.c (Fdbus_register_signal): Add match rule to
16726 Vdbus_registered_objects_table. (Bug#9581)
16727 (Fdbus_register_method, Vdbus_registered_objects_table):
16730 2011-09-24 Jim Meyering <meyering@redhat.com>
16732 do not ignore write error for any output size
16733 The previous change was incomplete.
16734 While it makes emacs --batch detect the vast majority of stdout
16735 write failures, errors were still ignored whenever the output size is
16736 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16737 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16738 && echo FAIL: ignored write error
16739 FAIL: ignored write error
16740 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16741 && echo FAIL: ignored write error
16742 FAIL: ignored write error
16743 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16745 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16747 * emacs.c (Fkill_emacs): In noninteractive mode exit
16748 non-successfully if a write error occurred on stdout. (Bug#9574)
16750 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16752 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16755 * dispextern.h (struct it): Update the comment documenting what
16758 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16760 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16761 a display string, extend search for cursor position to end of row.
16762 (find_row_edges): If the row ends in a newline from a display
16763 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16764 Handle the case of a display string with multiple newlines.
16765 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16766 non-empty line. Fixes confusing cursor motion with arrow keys at
16767 the beginning of a line that starts with whitespace.
16769 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16771 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16774 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16776 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16777 boolean (Bug#9154).
16779 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16781 * xdisp.c (display_line): Record maximum and minimum buffer
16782 positions even if no glyphs were produced (e.g., by a zero-width
16783 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16784 buffer positions that will be removed from the glyph row because
16786 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16787 column is beyond frame width: don't subtract 1 "pixel" when
16788 computing width of the stretch.
16789 (reseat_at_next_visible_line_start): Undo the change made on
16790 2011-09-17 that saved paragraph information and restored it after
16791 the call to `reseat'. (Bug#9545)
16793 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16795 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16796 and turn window cursor on if cleared (Bug#9415).
16798 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16800 * search.c (boyer_moore): Take unibyte characters from pattern
16801 literally. (Bug#9458)
16803 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16805 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16807 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16809 Fix minor problem found by static checking.
16810 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16811 initialized, to pacify gcc -Wuninitialized.
16813 * fileio.c: Report proper errno when syscall falls.
16814 (Finsert_file_contents): Save and restore errno,
16815 so that report_file_error outputs the correct diagnostic.
16816 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16818 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16820 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16822 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16824 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16825 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16827 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16829 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16830 about the current paragraph and restore it after the call to reseat.
16832 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16833 (bidi_find_paragraph_start): Search back for paragraph beginning
16834 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16835 (bidi_move_to_visually_next): Only trigger paragraph-related
16836 computations when the last character is a newline or at EOB, not
16837 just any NEUTRAL_B. (Bug#9470)
16839 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16840 truncated lines if point is covered by a display string. (Bug#9524)
16842 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16844 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16845 (cons_to_x_long): New function.
16846 (lisp_data_to_selection_data): Use it. Correct the test for
16847 short-versus-long data; it was negated. Break out of vector
16848 loop, for efficiency, when a long datum is discovered.
16850 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16852 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16854 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16856 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16857 GCC PR/17406) by declaring this function with external scope.
16859 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16861 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

16864 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16866 * editfns.c (Fformat): Correctly handle text properties on "%%".
16868 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16870 * xterm.c (x_draw_composite_glyph_string_foreground):
16871 * w32term.c (x_draw_composite_glyph_string_foreground):
16872 * term.c (encode_terminal_code):
16873 * composite.c (composition_update_it, get_composition_id):
16874 * xdisp.c (get_next_display_element)
16875 (fill_composite_glyph_string): Add comments about special meaning
16876 of TAB characters in a composition.
16878 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16880 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16881 This occurs when processing a multibyte format.
16882 Problem reported by Wolfgang Jenker.
16884 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16886 * xdisp.c (try_cursor_movement): Only check for exact match if
16887 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16889 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16891 Remove unused external symbols.
16892 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16893 * xdisp.c (calc_pixel_width_or_height): Now static.
16894 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16895 * indent.c (check_display_width):
16896 * w32term.c: Fix comment to match code.
16897 * xterm.c, xterm.h (x_catching_errors): Remove.
16899 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16901 * xselect.c: Use signed conversions more consistently (Bug#9498).
16902 (selection_data_to_lisp_data): Assume incoming selection data are
16903 signed integers, not unsigned. This is to be consistent with
16904 outgoing selection data, which was modified to use signed integers
16905 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16906 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16907 expects long, not unsigned long.
16909 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16911 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16912 computation of loop end. Reported by Johan Bockgård
16915 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16917 * frame.c (Fother_visible_frames_p): Function deleted.
16919 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16921 * indent.c (compute_motion): Process display vector front to back
16922 rather than the other way around. (Bug#2496)
16924 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16926 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16928 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16930 * minibuf.c (Fread_from_minibuffer): Doc fix.
16932 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16934 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16935 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16937 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16939 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16940 value for non-existent files.
16942 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16944 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16945 set its "size" to -1. This will set the modtime_size field of
16946 the corresponding buffer to -1, which is what
16947 verify-visited-file-modtime expects for files that do not exist.
16950 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16952 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16954 * lisp.h: ... from here. push_key_description is no longer
16955 defined in keyboard.c, so its declaration should not be in
16956 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16957 logically belongs with push_key_description.
16959 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16961 * buffer.h: Include <sys/types.h> instead of <time.h>.
16962 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16963 Problem reported by Herbert J. Skuhra.
16965 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16967 * xml.c (parse_region): Make the parsing work for
16968 non-comment-starting XML files again (bug#9144).
16970 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16972 * image.c (gif_load): Fix calculation of bottom and right corner.
16975 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16977 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16978 redisplay in small windows.
16980 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16982 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16984 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16986 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16987 Operate on live windows only.
16989 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16991 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16993 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16995 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16996 only under bidi iteration.
16998 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17000 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17002 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17004 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17005 Without this fix, the command to link temacs failed due to an
17006 undefined symbol __builtin_isnan. This is because
17007 /usr/include/iso/math_c99.h #defines isnan(x) to
17008 __builtin_isnan(x), but the bundled gcc, which identifies itself
17009 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17011 * floatfns.c (isnan): #undef, and then #define to a clone of
17013 (Fisnan): Always define, since it's always available now.
17014 (syms_of_floatfns): Always define isnan at the Lisp level.
17016 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17018 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17020 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17022 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17023 The previous code assumed that file offsets (off_t values) fit in
17024 EMACS_INT variables, which is not true on typical 32-bit hosts.
17025 The code messed up by falsely reporting buffer overflow in cases
17026 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17027 when "big" contains more than 2**29 bytes, even though this
17028 inserts just one byte and does not overflow the buffer.
17029 (Finsert_file_contents): Store file offsets as off_t
17030 values, not as EMACS_INT values. Check for overflow when
17031 converting between EMACS_INT and off_t. When checking for
17032 buffer overflow or for overlap, take the offsets into account.
17033 Don't use EMACS_INT for small values where int suffices.
17034 When checking for overlap, fix a typo: ZV was used where
17035 ZV_BYTE was intended.
17036 (Fwrite_region): Don't assume off_t fits into 'long'.
17037 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17039 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17041 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17043 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17045 sprintf-related integer and memory overflow issues (Bug#9412).
17047 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17048 (esprintf, exprintf, evxprintf): New functions.
17049 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17050 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17051 (modify_event_symbol): Do not assume that the length of
17052 name_alist_or_stem is safe to alloca and fits in int.
17053 (Fexecute_extended_command): Likewise for function name and binding.
17054 (Frecursion_depth): Wrap around reliably on integer overflow.
17055 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17056 since some callers pass EMACS_INT values.
17057 (Fsingle_key_description): Don't crash if symbol name contains more
17058 than MAX_ALLOCA bytes.
17059 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17060 (get_minibuffer): Arg is now EMACS_INT, not int.
17061 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17062 (esprintf, exprintf, evxprintf): New decls.
17063 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17065 * dbusbind.c (signature_cat): New function.
17066 (xd_signature, Fdbus_register_signal):
17067 Do not overrun buffer; instead, report string overflow.
17069 * dispnew.c (add_window_display_history): Don't overrun buffer.
17070 Truncate instead; this is OK since it's just a log.
17072 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17073 even if the time zone offset is outlandishly large.
17074 Don't mishandle offset == INT_MIN.
17076 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17077 when creating daemon; the previous buffer-overflow check was incorrect.
17079 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17080 which has the guts of the old verror function.
17082 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17083 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17085 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17086 (font_unparse_xlfd): Don't blindly alloca long strings.
17087 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17088 fits in int, when using sprintf. Use single snprintf to count
17089 length of string rather than counting it via multiple sprintfs;
17090 that's simpler and more reliable.
17091 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17092 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17093 sprintf, in case result does not fit in int.
17095 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17096 (fontset_from_font): Print it.
17098 * frame.c (tty_frame_count): Now printmax_t, not int.
17099 (make_terminal_frame, set_term_frame_name): Print it.
17100 (x_report_frame_params): In X, window IDs are unsigned long,
17101 not signed long, so print them as unsigned.
17102 (validate_x_resource_name): Check for implausibly long names,
17103 and don't assume name length fits in 'int'.
17104 (x_get_resource_string): Don't blindly alloca invocation name;
17105 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17108 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17109 (xg_check_special_colors, xg_set_geometry):
17110 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17112 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17113 Use esprintf, not sprintf, in case result does not fit in int.
17115 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17116 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17117 it as a large positive number.
17118 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17119 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17121 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17122 in case result does not fit in int.
17124 * print.c (float_to_string): Detect width overflow more reliably.
17125 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17126 buffer overrun. Don't assume list length fits in 'int'. Treat
17127 print length of 0 as 0, not as infinity; to be consistent with other
17128 uses of print length in this function. Don't overflow print length
17129 index. Don't assume hash table size fits in 'long', or that
17130 vectorlike size fits in 'unsigned long'.
17132 * process.c (make_process): Use printmax_t, not int, to format
17133 process-name gensyms.
17135 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17137 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17138 to avoid potential buffer overrun.
17140 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17141 if X resource line is longer than 512 bytes.
17143 * xfns.c (x_window): Make sprintf buffer a bit bigger
17144 to avoid potential buffer overrun.
17146 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17148 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17150 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17152 Integer overflow fixes for scrolling, etc.
17153 Without these, Emacs silently mishandles large integers sometimes.
17154 For example, "C-u 4294967297 M-x recenter" was treated as if
17155 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17157 * xdisp.c (try_window_id): Check Emacs fixnum range before
17158 converting to 'int'.
17160 * window.c (window_scroll_line_based, Frecenter):
17161 Check that an Emacs fixnum is in range before assigning it to 'int'.
17162 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17163 values converted from Emacs fixnums.
17164 (Frecenter): Don't wrap around a line count if it is out of 'int'
17165 range; instead, treat it as an extreme value.
17166 (Fset_window_configuration, compare_window_configurations):
17167 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17169 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17170 that can exceed INT_MAX. Check that EMACS_INT value is in range
17171 before assigning it to the (possibly-narrower) index.
17172 (match_limit): Don't assume that a fixnum can fit in 'int'.
17174 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17177 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17178 (Fvertical_motion): Don't wrap around LINES values that don't fit
17179 in 'int'. Instead, treat them as extreme values. This is good
17180 enough for windows, which can't have more than INT_MAX lines anyway.
17182 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17184 * Require libxml/parser.h to avoid compilation warning.
17186 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17188 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17189 since this reportedly can destroy thread storage.
17191 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17193 * syntax.c (find_defun_start): Update all cache variables if
17194 exiting early (Bug#9401).
17196 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17198 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17200 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17201 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17202 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17204 * term.c (tty_append_glyph): New function.
17205 (produce_stretch_glyph): Static function and its prototype deleted.
17207 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17210 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17212 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17213 when checking :margin (Bug#9390).
17214 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17215 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17216 so that the name doesn't mislead. All uses changed.
17218 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17220 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17223 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17225 * xdisp.c (move_it_to): Don't bail out early when reaching
17226 position beyond to_charpos, if we are scanning backwards.
17227 (move_it_vertically_backward): When DY == 0, make sure we get to
17228 the first character in the line after the newline.
17230 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17232 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17233 (ccl_driver): Do not generate an out-of-range pointer.
17234 (Fccl_execute_on_string): Remove unnecessary check for
17235 integer overflow, noted by Stefan Monnier in
17236 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17237 Remove a FIXME that didn't need fixing.
17238 Simplify the newly-introduced buffer reallocation code.
17240 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17242 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17244 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17246 Integer and memory overflow issues (Bug#9196).
17248 * doc.c (get_doc_string): Rework so that
17249 get_doc_string_buffer_size is the actual buffer size, rather than
17250 being 1 less than the actual buffer size; this makes xpalloc more
17253 * image.c (x_allocate_bitmap_record, cache_image):
17254 * xselect.c (Fx_register_dnd_atom):
17255 Simplify previous changes by using xpalloc.
17257 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17258 since either will do and ptrdiff_t is convenient with xpalloc.
17260 * charset.c (charset_table_size)
17261 (struct charset_sort_data.priority): Now ptrdiff_t.
17262 (charset_compare): Don't overflow if priorities differ greatly.
17263 (Fsort_charsets): Don't assume list length fits in int.
17264 Check for size-calculation overflow when allocating sort data.
17265 (syms_of_charset): Allocate an initial charset table that is
17266 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17268 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17270 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17271 The actual value is always <= INT_MAX, and leaving it unsigned made
17272 overflow checking harder.
17274 * dispextern.h (struct glyph_matrix.rows_allocated)
17275 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17276 with xpalloc. The values are still always <= INT_MAX.
17278 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17280 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17281 (SAFE_NALLOCA): New macro.
17283 * region-cache.c (struct boundary.pos, find_cache_boundary)
17284 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17285 (set_cache_region, invalidate_region_cache)
17286 (revalidate_region_cache, know_region_cache, region_cache_forward)
17287 (region_cache_backward, pp_cache):
17288 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17289 so that ptrdiff_t * can be passed to xpalloc.
17290 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17291 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17292 (pp_cache): Don't assume cache_len fits in int.
17293 * region-cache.h: Adjust extern decls to match.
17295 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17296 EMACS_INT, since either will do, for xpalloc.
17298 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17299 (xnmalloc, xnrealloc, xpalloc): New functions.
17301 * bidi.c (bidi_shelve_header_size): New constant.
17302 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17303 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17305 * bidi.c (bidi_cache_shrink):
17306 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17308 Don't update size of array until after memory allocation succeeds,
17309 because xmalloc/xrealloc may not return.
17310 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17311 now that we have proper integer overflow checking.
17312 (record_overlay_string, overlay_strings): Catch overflows when
17313 calculating size of overlay_str_buf.
17315 * callproc.c (Fcall_process): Check for size overflow when
17316 calculating size of args2.
17317 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17318 Normally we prefer signed values, but sticking with ptrdiff_t would
17319 require adding more-complicated checks.
17321 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17322 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17323 Redo buffer-overflow calculations to avoid integer overflow.
17324 Add a FIXME comment where memory seems to be over-allocated.
17326 * character.c (Fstring): Check for size-calculation overflow.
17328 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17329 unnecessary integer overflow. Check for size overflow.
17330 (encode_coding_object): Don't update size until xmalloc succeeds.
17332 * composite.c (get_composition_id): Check for overflow in glyph
17333 length calculations.
17335 Integer and memory overflow fixes for display code.
17336 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17337 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17338 (scrolling_window): Check for overflow in size calculations.
17339 (line_draw_cost, realloc_glyph_pool, add_row_entry):
17340 Don't assume glyph table len fits in int.
17341 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
17342 (row_table_size): Now ptrdiff_t, not int.

17362 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17364 * emacs.c (main): Do not reallocate argv, since there is a null at
17365 the end that can be overwritten, and this way there's no need to
17366 worry about size-calculation overflow.

17496 (X_LONG_MIN): New macros.
17497 Use them to make the following changes clearer.
17498 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

17501 (SELECTION_QUANTUM): Remove, replacing with ...
17502 (selection_quantum): ... new function, which avoids overflow.
17504 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17505 assumption that selection length fits in 'int'.

17522 Don't store size until memory allocation succeeds.
17523 (x_get_window_property): Plug memory leak on memory exhaustion.
17524 Don't double-block input; malloc is safe here. Don't assume 2**34
17525 - 4 fits in unsigned long. Add an xassert to check
17526 XGetWindowProperty overflow. Be more careful about overflow
17527 calculations, and distinguish size from memory overflow better.

17534 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17535 result parameters unless successful. Rely on cons_to_unsigned
17536 to report problems with elements; the old code wasn't right anyway.
17537 (x_check_property_data): Check for int overflow; we cannot use
17538 a wider type due to X limits.

17571 * lisp.h (hash_lookup, hash_put):
17572 * minibuf.c (Ftest_completion):
17573 Use ptrdiff_t for hash table indexes, not int (which is too
17574 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17575 32-bit --with-wide-int hosts).
17577 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17578 Add a FIXME comment about memory leaks.

17607 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17608 (x_send_scroll_bar_event): Likewise. Check that the size does not
17609 exceed limits imposed by XClientMessageEvent, as well as the usual
17610 ptrdiff_t and size_t limits.
17612 * keyboard.c: Overflow, signedness and related fixes.
17613 (make_lispy_movement): Use same integer type in forward decl
17614 that is used in the definition.
17615 (read_key_sequence, keyremap_step):
17616 Change bufsize argument back to int, undoing my 2011-03-30 change.
17617 We prefer signed types, and int is wide enough here.
17618 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17619 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17620 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17621 length, not size_t. Use ptrdiff_t for index, not int.
17622 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17623 possibility of integer overflow.

17651 Prefer int to unsigned where either will do.
17652 (tiff_handler): New function, combining the cores of the
17653 old tiff_error_handler and tiff_warning_handler.

17655 stack buffer overflows. It uses only the features of vsnprintf
17656 that are common to both POSIX and native Microsoft.
17657 (tiff_error_handler, tiff_warning_handler): Use it.
17658 (tiff_load, gif_load, imagemagick_load_image):
17659 Don't assume :index value fits in 'int'.
17660 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

17662 the integer types that MagickCropImage accepts. Don't assume
17663 Vimagemagick_render_type has a nonnegative value. Don't assume
17664 size_t fits in 'long'.
17665 (gs_load): Use printmax_t to print the widest integers possible.

17702 buffers, return left-to-right.
17703 (set_cursor_from_row): Consider candidate row a win if its glyph

17705 positioning on the newline at EOL of R2L text within L2R
17706 paragraph, and vice versa.
17707 (try_cursor_movement): Check continued rows, in addition to
17708 continuation rows. Fixes unwarranted scroll when point enters a
17709 continued line of R2L text within an L2R paragraph, or vice versa.
17710 (cursor_row_p): Consider the case of point being equal to
17711 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17712 from the end of a short line to the beginning of a continued line
17713 of R2L text within L2R paragraph.

17740 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17741 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17742 candidate is selected by the mouse, and that candidate has a
17743 composed character under the mouse.
17745 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17746 coordinates reported by pos-visible-in-window-p for a composed

17756 consider it a hit if to_charpos is anywhere in the range of the
17757 composed buffer positions.
17759 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17761 * image.c (gif_load): Don't assume that each subimage has the same
17762 dimensions as the base image. Handle disposal method that is
17763 "undefined" by the gif spec (Bug#9335).
17765 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17767 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17776 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17777 a composition, take its buffer position from IT->cmp_it.charpos.
17778 Fixes cursor positioning at the beginning of a line that begins
17779 with a composed character.
17781 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17783 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17784 character bidirectional type, use STRONG_L instead. Fixes crashes
17785 in a buffer produced by `describe-categories'.
17787 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17788 members before the level stack, so they would be saved and
17789 restored when copying iterator state. Fixes incorrect reordering
17790 around TABs covered by display properties.
17792 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17794 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
17796 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
17798 * eval.c (internal_condition_case, internal_condition_case_1)
17799 (internal_condition_case_2, internal_condition_case_n):
17800 Remove unnecessary aborts (Bug#9081).
17802 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17804 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17805 has no `load' handler, try opening the file locally. (Bug#9311)
17807 2011-08-16 Ken Brown <kbrown@cornell.edu>
17809 * gmalloc.c: Expand comment.
17811 2011-08-16 Eli Zaretskii <eliz@gnu.org>
17813 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17814 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
17816 2011-08-16 Ken Brown <kbrown@cornell.edu>
17818 Fix memory allocation problems in Cygwin build (Bug#9273).

17825 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17827 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17828 in the static heap.
17829 [CYGWIN] (special_realloc): New function.
17830 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
17831 requests to realloc storage in the static heap.

17842 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
17844 * dispextern.h: Fix a typo in the comment to bidi_type_t.
17846 * chartab.c: Improve commentary for the uniprop_table API.
17848 * bidi.c (bidi_paragraph_init): Support zero value of
17849 bidi_ignore_explicit_marks_for_paragraph_level.
17850 (bidi_initialize): Use uniprop_table instead of including
17851 biditype.h and bidimirror.h.
17853 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
17854 coordinates of the iterator when restoring from ppos_it.
17857 2011-08-14 Kenichi Handa <handa@m17n.org>
17859 * process.c (create_process): Call setup_process_coding_systems
17860 after the pid of the process is set to -1 (Bug#8162).
17862 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17864 * xdisp.c (move_it_in_display_line_to): Don't invoke
17865 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17866 ppos_it. Fixes vertical cursor motion when line beginning is
17867 covered by an image. (Bug#9296)
17869 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17871 * nsterm.h (ns_run_ascript): Declare.
17872 (NSAPP_DATA2_RUNASSCRIPT): Define.
17874 * nsfns.m (as_script, as_result, as_status): New static variables.
17875 (ns_run_ascript): New function.
17876 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17877 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17878 the event loop. Get status from as_status (Bug#7276).
17880 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17881 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17882 the event loop (Bug#7276).
17884 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17886 * gnutls.c (QCgnutls_bootprop_priority)
17887 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17888 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17889 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17890 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17891 (QCgnutls_bootprop_verify_hostname_error)
17892 (QCgnutls_bootprop_callbacks_verify): Rename from
17893 Qgnutls_bootprop_..., all uses changed.
17895 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17898 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17900 * xfaces.c (Qframe_set_background_mode): Now static.

17905 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17907 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17908 (Fnetwork_interface_list): Allocate in increments of bytes instead
17909 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17910 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17912 (struct ifflag_def): notrailers is smart on OSX.
17913 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17914 Get hardware address with getifaddrs if available.
17916 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17918 * xdisp.c (iterate_out_of_display_property): xassert that
17919 IT->position is set to within IT->object's boundaries. Break from
17920 the loop as soon as EOB is reached; avoids infloops in redisplay
17921 when IT->position is set up wrongly due to some bug.
17922 Set IT->current to match the bidi iterator unconditionally.
17923 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17924 entry. Force push_it to save on the stack the current
17925 buffer/string position, to be restored by pop_it. Fix flags in
17926 the iterator structure wrt the object coming from a display
17927 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17928 properties. (Bug#9284)
17930 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17932 * fontset.c (fontset_get_font_group): Add proper type checks.
17935 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

17938 and LC_VERSION_MIN_MACOSX.
17939 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17940 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17942 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17944 * xdisp.c (forward_to_next_line_start): Allow to use the
17945 no-display-properties-and-no-overlays under bidi display.
17946 Set disp_pos in the bidi iterator to avoid searches for display
17947 properties and overlays.
17949 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17951 * editfns.c (Fset_time_zone_rule): Document relationship with the

17955 the font entity extracted from the cache (Bug#8109).
17957 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17959 * composite.c (autocmp_chars): Don't reset point. That is done by
17960 restore_point_unwind (Bug#5984).
17962 2011-08-07 Juri Linkov <juri@jurta.org>
17964 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17965 to show the arg `TIME' instead of `TIMEVAL'.
17967 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17969 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17970 display property strides EOL and includes a newline, as in
17971 longlines-mode. (Bug#9254)
17972 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17973 word-wrap under bidirectional display. (Bug#9224)
17975 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17976 is non-zero, even if the data buffer is NULL. Fixes a crash in
17977 vertical-motion with longlines-mode. (Bug#9254)
17979 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17981 * bidi.c <bidi_cache_total_alloc>: Now static.
17982 (bidi_initialize): Initialize bidi_cache_total_alloc.
17984 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17987 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17988 amount allocated this far in `bidi_cache_total_alloc'.
17989 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17990 non-zero, only free the data buffer without restoring the cache
17991 contents. All callers changed.
17993 * dispextern.h (bidi_unshelve_cache): Update prototype.
17995 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17996 (move_it_in_display_line, move_it_to)
17997 (move_it_vertically_backward, move_it_by_lines): Replace the call
17998 to xfree to an equivalent call to bidi_unshelve_cache.
17999 (move_it_in_display_line_to): Fix logic of returning
18000 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
18002 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18004 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
18005 came from a string character with a `cursor' property. (Bug#9229)
18007 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18009 * Makefile.in (LIB_PTHREAD): New variable.
18010 (LIBES): Add LIB_PTHREAD (Bug#9216).
18012 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
18013 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
18015 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
18017 * regex.c (re_iswctype): Remove some redundant boolean conversions.
18019 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18021 * xterm.c (x_find_topmost_parent): New function.
18022 (x_set_frame_alpha): Find topmost parent window with
18023 x_find_topmost_parent and set the property there also (bug#9181).
18024 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
18026 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
18028 * callproc.c (Fcall_process): Avoid vfork clobbering
18029 the local vars buffer, coding_systems, current_dir.
18031 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
18033 * keymap.c (Fmake_composed_keymap): Move to subr.el.
18035 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
18037 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
18038 so that it is not optimized away.
18040 * xdisp.c (compute_display_string_pos): Remove unused local.
18042 2011-08-02 Eli Zaretskii <eliz@gnu.org>
18044 Fix slow cursor motion and scrolling in large buffers with
18045 selective display, like Org Mode buffers. (Bug#9218)
18047 * dispextern.h (struct bidi_it): New member disp_prop_p.
18049 * xdisp.c: Remove one-slot cache of display string positions.
18050 (compute_display_string_pos): Accept an additional argument
18051 DISP_PROP_P; callers changed. Scan at most 5K characters forward
18052 for a display string or property. If found, set DISP_PROP_P
18055 * bidi.c (bidi_fetch_char): Accept an additional argument
18056 DISP_PROP_P, and pass it to compute_display_string_pos.
18057 Only handle text covered by a display string if DISP_PROP_P is returned
18058 non-zero. All callers of bidi_fetch_char changed.
18060 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
18062 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
18064 2010-12-03 Don March <don@ohspite.net>
18066 * keymap.c (Fdefine_key): Fix non-prefix key error message when
18067 last character M-[char] is translated to ESC [char] (bug#7541).
18069 2011-08-02 Kenichi Handa <handa@m17n.org>
18071 * lisp.h (uniprop_table): Extern it.
18073 * chartab.c (uniprop_table): Make it non-static.
18075 2011-08-01 Eli Zaretskii <eliz@gnu.org>
18077 * xdisp.c (forward_to_next_line_start): Accept additional argument
18078 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18080 (reseat_at_next_visible_line_start): Use the bidi iterator state
18081 returned by forward_to_next_line_start to restore the state of
18082 it->bidi_it after backing up to previous newline. (Bug#9212)
18084 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18086 * regex.c (re_comp): Protoize.
18087 (re_exec): Fix return type.
18088 (regexec): Fix type of `ret'. (Bug#9203)
18090 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18092 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18093 This is needed if max-image-size is a floating-point number.
18095 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18097 * print.c (print_object): Print empty symbol as ##.
18099 * lread.c (read1): Read ## as empty symbol.
18101 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18103 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
18104 setting frame foreground color (Bug#9175).
18105 (x_set_background_color): Likewise.
18107 * nsmenu.m (-setText): Size tooltip dimensions precisely to
18108 contents (Bug#9176).
18109 (EmacsTooltip -init): Remove bezels and add shadows to
18112 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18113 or scroll bar (Bug#8470).
18115 * nsfont.m (nsfont_open): Remove assignment to voffset and
18116 unnecessary vars hshink, expand, hd, full_height, min_height.
18117 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
18119 * nsterm.h (nsfont_info): Remove voffset field.
18121 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18123 Implement strike-through and overline on NextStep (Bug#8863).
18125 * nsfont.m (nsfont_open): Use underline position provided by font,
18126 instead of hard-coded value of 2.
18127 (nsfont_draw): Call ns_draw_text_decoration instead.
18129 * nsterm.h: Add declaration for ns_draw_text_decoration.
18131 * nsterm.m (ns_draw_text_decoration): New function for drawing
18132 underline, overline, and strike-through.
18133 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
18134 ns_draw_text_decoration. Change treatment of cursor drawing to
18135 accommodate underlining, etc.
18137 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18139 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18142 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18144 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18145 Without this fix, if a signal arrives just after memory fills up,
18146 'malloc' might be invoked reentrantly.
18148 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18149 In other words, assume that every image size is allowed, on non-X
18150 hosts. This assumption is probably wrong, but it lets Emacs compile.
18152 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18154 * regex.c (re_iswctype): Convert return values to boolean.
18156 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18158 * xdisp.c (compute_display_string_pos): Don't use cached display
18159 string position if the buffer had its restriction changed.
18162 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18164 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18166 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18168 Integer signedness and overflow and related fixes. (Bug#9079)
18170 * bidi.c: Integer size and overflow fixes.
18171 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18172 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18173 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18174 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18175 (bidi_find_other_level_edge):
18176 Use ptrdiff_t instead of EMACS_INT where either will do.
18177 This works better on 32-bit hosts configured --with-wide-int.
18178 (bidi_cache_ensure_space): Check for size-calculation overflow.
18179 Use % rather than repeated addition, for better worst-case speed.
18180 Don't set bidi_cache_size until after xrealloc returns, because it
18182 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18183 (bidi_cache_ensure_space): Also check that the bidi cache size
18184 does not exceed that of the largest Lisp string or buffer. See Eli
18185 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18187 * alloc.c (__malloc_size_t): Remove.
18188 All uses replaced by size_t. See Andreas Schwab's note
18189 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18191 * image.c: Improve checking for integer overflow.
18192 (check_image_size): Assume that f is nonnull, since
18193 it is always nonnull in practice. This is one less thing to
18194 worry about when checking for integer overflow later.
18195 (x_check_image_size): New function, which checks for integer
18196 overflow issues inside X.
18197 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18198 This removes the need for a memory_full check.
18199 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18200 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18201 (xbm_read_bitmap_data): Change locals back to 'int', since
18202 their values must fit in 'int'.
18203 (xpm_load_image, png_load, tiff_load):
18204 Invoke x_create_x_image_and_pixmap earlier,
18205 to avoid much needless work if the image is too large.
18206 (tiff_load): Treat overly large images as if
18207 x_create_x_image_and_pixmap failed, not as malloc failures.
18208 (gs_load): Use x_check_image_size.
18210 * gtkutil.c: Omit integer casts.
18211 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18212 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18214 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18216 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18217 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18218 would wrongly return t on a 64-bit host.
18220 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18221 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18222 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18223 and therefore cause GCC to emit a bogus diagnostic in some cases.
18225 * image.c: Integer signedness and overflow and related fixes.
18226 This is not an exhaustive set of fixes, but it's time to
18227 record what I've got.
18228 (lookup_pixel_color, check_image_size): Remove redundant decls.
18229 (check_image_size): Don't assume that arbitrary EMACS_INT values
18230 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18231 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18232 (tiff_load, imagemagick_load_image):
18233 Check for overflow in size calculations.
18234 (x_create_x_image_and_pixmap): Remove unnecessary test for
18235 xmalloc returning NULL; that can't happen.
18236 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18237 (xpm_color_bucket): Use better integer hashing function.
18238 (xpm_cache_color): Don't possibly over-allocate memory.
18239 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18240 (gif_memory_source):
18241 Use ptrdiff_t, not int or size_t, to record sizes.
18242 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18243 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18244 either works, as we prefer signed integers.
18245 (tiff_read_from_memory, tiff_write_from_memory):
18246 Return tsize_t, not size_t, since that's what the TIFF API wants.
18247 (tiff_read_from_memory): Don't fail simply because the read would
18248 go past EOF; instead, return a short read.
18249 (tiff_load): Omit no-longer-needed casts.
18250 (Fimagemagick_types): Don't assume size fits into 'int'.
18252 Improve hashing quality when configured --with-wide-int.
18253 * fns.c (hash_string): New function, taken from sxhash_string.
18254 Do not discard information about ASCII character case; this
18255 discarding is no longer needed.
18256 (sxhash-string): Use it. Change sig to match it. Caller changed.
18257 * lisp.h: Declare it.
18258 * lread.c (hash_string): Remove, since we now use fns.c's version.
18259 The fns.c version returns a wider integer if --with-wide-int is
18260 specified, so this should help the quality of the hashing a bit.
18262 * emacs.c: Integer overflow minor fix.
18263 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18264 Define only if GNU_LINUX.
18265 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18267 * dispnew.c: Integer signedness and overflow fixes.
18268 Remove unnecessary forward decls, that were a maintenance hassle.
18269 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18271 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18272 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18273 (prepare_desired_row, line_draw_cost):
18274 Use int, not unsigned, where either works.
18275 (save_current_matrix, restore_current_matrix):
18276 Use ptrdiff_t, not size_t, where either works.
18277 (init_display): Check for overflow more accurately, and without
18278 relying on undefined behavior.
18280 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18281 Remove, replacing with the new symbols in lisp.h. All uses changed.
18282 * fileio.c (make_temp_name):
18283 * filelock.c (lock_file_1, lock_file):
18284 * xdisp.c (message_dolog):
18285 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18286 Use pMd etc. instead.
18287 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18288 replacing the pWIDE etc. symbols removed from editfns.c.
18290 * keyboard.h (num_input_events): Now uintmax_t.
18291 This is (very slightly) less likely to mess up due to wraparound.
18294 * buffer.c: Integer signedness fixes.
18295 (alloc_buffer_text, enlarge_buffer_text):
18296 Use ptrdiff_t rather than size_t when either will do, as we prefer
18299 * alloc.c: Integer signedness and overflow fixes.
18300 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18301 (__malloc_size_t): Default to size_t, not to int.
18302 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18303 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18304 Prefer ptrdiff_t to size_t when either would do, as we prefer
18306 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18307 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18308 Now const. Initialize with values that are in range even if char
18310 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18311 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18312 These functions do the right thing with sizes > 2**32.
18313 (check_depth): Now ptrdiff_t, not int.
18314 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18315 Adjust to new way of storing sizes. Check for size overflow bugs
18317 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18318 slightly wrong anyway, as it missed one instance of
18319 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18320 (refill_memory_reserve): Omit needless cast to size_t.
18321 (mark_object_loop_halt): Mark as externally visible.
18323 * xselect.c: Integer signedness and overflow fixes.
18324 (Fx_register_dnd_atom, x_handle_dnd_message):
18325 Use ptrdiff_t, not size_t, since we prefer signed.
18326 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18327 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18328 x_dnd_atoms_size and x_dnd_atoms_length.
18330 * doprnt.c: Prefer signed to unsigned when either works.
18332 * doprnt.c (doprnt):
18334 * xdisp.c (vmessage):
18335 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18336 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18337 prefer signed arithmetic to avoid comparison confusion.
18338 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18339 but is a bit tricky.
18341 Assume freestanding C89 headers, string.h, stdlib.h.
18342 * data.c, doprnt.c, floatfns.c, print.c:
18343 Include float.h unconditionally.
18344 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18345 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18346 * regex.c: Likewise for stddef.h, string.h.
18347 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18348 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18349 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18350 (STDC_HEADERS): Remove obsolete defines.
18351 * sysdep.c: Include limits.h unconditionally.
18353 Assume support for memcmp, memcpy, memmove, memset.
18354 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18355 * regex.c (memcmp, memcpy):
18356 Remove; we assume C89 now.
18358 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18359 (__malloc_safe_bcopy): Remove; no longer needed.
18361 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18362 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18363 well either way, and we prefer signed to unsigned.
18365 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18367 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18368 closes the connection while we're reading (bug#9182).
18370 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18372 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18373 are specified (Bug#9168).
18375 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18377 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18378 Found by GCC static checking and --with-wide-int on a 32-bit host.
18380 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18382 * xdisp.c (compute_display_string_pos): Fix logic of caching
18383 previous display string position. Initialize cached_prev_pos to
18384 -1. Fixes slow-down at the beginning of a buffer.
18386 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18388 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18389 for attrs[LFACE_FONTSET_INDEX].
18391 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18393 * xml.c (parse_region): Remove unused local
18394 that was recently introduced.
18396 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18398 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18399 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18401 * xdisp.c (move_it_in_display_line_to): Record the best matching
18402 position for TO_CHARPOS while scanning the line, and restore it on
18403 exit if none of the characters scanned was an exact match.
18404 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18405 when exact match is impossible due to invisible text, and the
18406 lines are truncated.
18408 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18410 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18413 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18415 Fix a significant slow-down of cursor motion with C-n, C-p,
18416 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18417 auto-repeat under bidi redisplay in fontified buffers.
18418 * xdisp.c (compute_stop_pos_backwards): New function.
18419 (next_element_from_buffer): Call compute_stop_pos_backwards to
18420 find a suitable prev_stop when we find ourselves before
18422 (reseat): Don't look for prev_stop, as that could mean a very long
18424 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18425 <cached_disp_overlay_modiff>: Cache for last found display string
18427 (compute_display_string_pos): Return the cached position if asked
18428 about the same buffer in the same area of character positions, and
18429 the buffer wasn't changed since the time the display string
18430 position was cached.
18432 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18434 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18435 is an integer, which is important for empty lines. (Bug#9149)
18437 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18439 * frame.c (Fmodify_frame_parameters): In tty case, update the
18440 default face if necessary (Bug#4238).
18442 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18444 * editfns.c (Fstring_to_char): No need to explain what a character
18445 is in the docstring (Bug#6576).
18447 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18449 * xml.c (parse_region): Make sure we always return a tree.
18451 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18453 * xml.c (parse_region): If a document contains only comments,
18456 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18458 * xml.c (make_dom): Return comments, too.
18460 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18463 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18464 and the surrounding thread.
18465 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18466 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18467 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18469 * s/openbsd.h (BROKEN_SIGIO): Define.
18470 * unexelf.c (unexec) [__OpenBSD__]:
18471 Don't update the .mdebug section of the Alpha COFF symbol table.
18473 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18475 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18478 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18480 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18481 This fixes some race conditions on the permissions of any newly
18484 * alloc.c (valid_pointer_p): Use pipe, not open.
18485 This fixes some permissions issues when debugging.
18487 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18488 If fchown fails to set both uid and gid, try to set just gid,
18489 as that is sometimes allowed. Adjust the file's mode to eliminate
18490 setuid or setgid bits that are inappropriate if fchown fails.
18492 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18494 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18495 to compare Lisp_Objects.
18496 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18497 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18498 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18500 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18502 * lread.c (read_integer): Unread even EOF character.
18503 (read1): Likewise. Properly record start position of symbol.
18505 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18506 symbol character follows.
18508 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18510 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18511 This works around a problem with the previous change to Fcopy_file.
18512 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18513 and without this change, GCC might complain about discarding
18514 fchown's return value.
18516 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18518 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18520 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18522 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18524 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18526 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18527 it's used from the C level.
18529 * process.c: Use the same condition for POLL_FOR_INPUT in both
18530 keyboard.c and process.c (bug#1858).
18532 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18534 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18535 (Fgnutls_boot): Use it.
18537 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18539 * doc.c (Fsubstitute_command_keys): Revert last change.
18541 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18543 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18544 quotes the next character, and doesn't affect other longer
18545 sequences (bug#8935).
18547 * lread.c (syms_of_lread): Clarify that is isn't only
18548 `eval-buffer' and `eval-defun' that's affected by
18549 `lexical-binding' (bug#8460).
18551 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18553 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18554 bidi redisplay when a line includes both an image and is truncated.
18556 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18558 Fix minor problems found by static checking.
18559 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18560 (elsz): Now a signed constant, not a size_t var. We prefer signed
18561 types to unsigned, to avoid integer comparison confusion. Without
18562 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18563 "cannot optimize loop, the loop counter may overflow", a symptom
18565 * indent.c (Fvertical_motion): Mark locals as initialized.
18566 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18568 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18570 * search.c (Fre_search_backward): Mention `case-fold-search' in
18571 all the re_search_* functions (bug#8138).
18573 * keyboard.c (Fopen_dribble_file): Document when the file is
18576 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18578 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18581 Support bidi reordering of display and overlay strings.

18583 (compute_display_string_end): Accept additional argument STRING.
18584 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18585 (reseat_to_string): Initialize bidi_it->string.s and
18586 bidi_it->string.schars.
18587 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18588 NULL (avoids a crash in bidi_paragraph_init).
18589 Initialize itb.string.lstring.
18590 (init_iterator): Call bidi_init_it only of a valid
18591 buffer position was specified. Initialize paragraph_embedding to
18593 (reseat_to_string): Initialize the bidi iterator.
18594 (display_string): If we need to ignore text properties of
18595 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18596 original value of -1 will not work with bidi.)
18597 (compute_display_string_pos): First arg is now struct
18598 `text_pos *'; all callers changed. Support display properties on
18600 (compute_display_string_end): Support display properties on Lisp
18602 (init_iterator, reseat_1, reseat_to_string): Initialize the
18603 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18604 when iterating on a string not from display properties).
18605 (compute_display_string_pos, compute_display_string_end):
18606 Fix calculation of the object to scan. Fixes an error when using
18608 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18609 base_level_stop; instead, set base_level_stop to BEGV.
18610 Fixes crashes in vertical-motion.
18611 (next_element_from_buffer): Improve commentary for when
18612 the iterator is before prev_stop.
18613 (init_iterator): Initialize bidi_p from the default value of
18614 bidi-display-reordering, not from buffer-local value. Use the
18615 buffer-local value only if initializing for buffer iteration.
18616 (handle_invisible_prop): Support invisible properties on strings
18617 that are being bidi-reordered.
18618 (set_iterator_to_next): Support bidi reordering of C strings and
18620 (next_element_from_string): Support bidi reordering of Lisp
18622 (handle_stop_backwards): Support Lisp strings as well.
18623 (display_string): Support display of R2L glyph rows.
18624 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18625 (init_iterator): Don't initialize it->bidi_p for strings
18627 (reseat_to_string): Initialize it->bidi_p for strings here.
18628 (next_element_from_string, next_element_from_c_string)
18629 (next_element_from_buffer): Add xassert's for correspondence
18630 between IT's object being iterated and it->bidi_it.string
18632 (face_before_or_after_it_pos): Support bidi iteration.
18633 (next_element_from_c_string): Handle the case of the first string
18634 character that is not the first one in the visual order.
18635 (get_visually_first_element): New function, refactored from common
18636 parts of next_element_from_buffer, next_element_from_string, and
18637 next_element_from_c_string.
18638 (tool_bar_lines_needed, redisplay_tool_bar)
18639 (display_menu_bar): Force left-to-right direction. Add a FIXME
18640 comment for making that be controlled by a user option.
18641 (push_it, pop_it): Save and restore the state of the
18642 bidi iterator. Save and restore the bidi_p flag.
18643 (pop_it): Iterate out of display property for string iteration as
18645 (iterate_out_of_display_property): Support iteration over strings.
18646 (handle_single_display_spec): Set up it->bidi_it for iteration
18647 over a display string, and call bidi_init_it.
18648 (handle_single_display_spec, next_overlay_string)
18649 (get_overlay_strings_1, push_display_prop): Set up the bidi
18650 iterator for displaying display or overlay strings.
18651 (forward_to_next_line_start): Don't use the shortcut if
18653 (back_to_previous_visible_line_start): If handle_display_prop
18654 pushed the iterator stack, restore the internal state of the bidi
18655 iterator by calling bidi_pop_it same number of times.
18656 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18657 and we are bidi-iterating, don't decrement the iterator position;
18658 instead, set the first_elt flag in the bidi iterator, to produce
18660 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18661 (push_display_prop): xassert that we are iterating a buffer.
18662 (push_it, pop_it): Save and restore paragraph_embedding member.
18663 (handle_single_display_spec, next_overlay_string)
18664 (get_overlay_strings_1, reseat_1, reseat_to_string)
18665 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18666 correctly. Don't assume unibyte strings are not bidi-reordered.
18667 (compute_display_string_pos)
18668 (compute_display_string_end): Fix handling the case of C string.
18669 (push_it, pop_it): Save and restore from_disp_prop_p.
18670 (handle_single_display_spec, push_display_prop): Set the
18671 from_disp_prop_p flag.
18672 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
18673 (pop_it): Call iterate_out_of_display_property only if we are
18674 popping after iteration over a string that came from a display
18675 property. Fix a typo in popping stretch info. Add an assertion

19129 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
19131 Random fixes. E.g., (random) never returned negative values.
19132 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19133 subseconds part to the entropy, as that's a bit more random.
19134 Prefer signed to unsigned, since the signedness doesn't matter and
19135 in general we prefer signed. When given a limit, use a
19136 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19137 latter isn't right if USE_2_TAGS_FOR_INTS.
19138 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19139 not 0..VALMASK. Don't discard "excess" bits that random () returns.
19141 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
19143 * textprop.c (text_property_stickiness):
19144 Obey Vtext_property_default_nonsticky.

19151 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19152 This is more efficient than Ffile_directory_p and avoids a minor race.
19154 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19156 * buffer.c (Foverlay_put): Say what the return value is
19159 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19160 is a directory before asking whether to use the file name
19162 (barf_or_query_if_file_exists): Make the "File is a directory"
19163 error be more correct.
19165 * fns.c (Frequire): Remove the mention of the .gz files, since
19166 that's installation-specific, but keep the mention of
19167 `get-load-suffixes'.
19169 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
19171 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

19176 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
19177 (syms_of_gnutls): Remove duplicate DEFSYM for
19178 Qgnutls_bootprop_verify_hostname_error, an error for
19179 Qgnutls_bootprop_verify_error (which is no longer used).
19181 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19182 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19183 Also (re)move comments that are misplaced or no longer relevant.
19185 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
19187 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

19212 * lread.c (syms_of_lread): Mention single symbols defined by
19213 `defvar' or `defconst' (bug#7154).
19215 * fns.c (Frequire): Mention .el.gz files (bug#7314).
19216 (Frequire): Mention get-load-suffixes.
19218 2011-07-02 Martin Rudalics <rudalics@gmx.at>

19246 (syms_of_keymap): Defsubr make-composed-keymap.
19247 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

19284 * eval.c (struct backtrace): Simplify and port the data structure.
19285 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19286 signed bit field, as this assumption is not portable and it makes
19287 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19288 "char debug_on_exit : 1" as this is not portable either; instead,
19289 use the portable "unsigned int debug_on_exit : 1". Remove unused
19290 member evalargs. Remove obsolete comments about cc bombing out.
19292 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
19294 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

19362 (emacs_fixed_get_preferred_height): Use min_width/height from
19363 frames size_hint to set minimum and natural (Bug#8919).
19364 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
19365 and use min_width/height from frames size_hint to set
19366 min_width/height (Bug#8919).

19458 * print.c (printchar, strout): Check for string overflow.
19459 (PRINTPREPARE, printchar, strout):
19460 Don't set size unless allocation succeeds.
19462 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19463 for sizes. Check for string overflow more accurately.

19478 to improve quality of diagnostics for out-of-range radices.
19479 Calculate buffer size correctly for out-of-range radices.
19480 (read1): Check for integer overflow in radices, and in
19481 read-circle numbers.
19482 (read_escape): Avoid int overflow.
19483 (Fload, openp, read_buffer_size, read1)
19484 (substitute_object_recurse, read_vector, read_list, map_obarray):
19485 Use ptrdiff_t, not int, for sizes.

19505 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19507 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19508 The following patches are for when GLYPH_DEBUG && !XASSERT.
19509 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19510 * dispnew.c (flush_stdout):
19511 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19512 Mark as externally visible.
19513 * dispnew.c (check_window_matrix_pointers): Now static.
19514 * dispnew.c (window_to_frame_vpos):
19515 * xfns.c (unwind_create_frame):

19522 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19524 (debug_method_add): Use va_list and vsprintf rather than relying
19525 on undefined behavior with wrong number of arguments.
19526 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19527 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19528 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19529 since we're not interested in debugging glyphs with old libraries.
19530 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19531 GCC 4.6.0's static checking.
19533 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19535 Integer overflow and signedness fixes (Bug#8873).

19552 (.bitmaps_last, struct x_output.icon_bitmap):
19553 Use ptrdiff_t, not int, for bitmap indexes.
19554 (x_allocate_bitmap_record): Check for size overflow.
19555 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19557 Use ptrdiff_t, not int, for overlay counts.
19558 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19559 * editfns.c (overlays_around, get_pos_property):
19560 * textprop.c (get_char_property_and_overlay):
19561 * xdisp.c (next_overlay_change, note_mouse_highlight):
19562 * xfaces.c (face_at_buffer_position):
19563 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19564 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19565 (Fnext_overlay_change, Fprevious_overlay_change)
19566 (mouse_face_overlay_overlaps, Foverlays_in):
19567 Use ptrdiff_t, not int, for sizes.
19568 (overlays_at, overlays_in): Check for size-calculation overflow.
19570 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19572 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19573 (x_session_initialize): Do not assume string length fits in int.
19575 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19576 This is unlikely, but can occur if DPI is outlandish.
19578 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19579 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19581 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19582 * xrdb.c (magic_file_p, search_magic_path):
19583 Omit last arg SUFFIX; it was always 0. All callers changed.
19584 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19586 * xfont.c (xfont_match): Avoid need for strlen.
19588 * xfns.c: Don't assume strlen fits in int.
19589 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19591 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19592 not unsigned long, as we prefer signed integers. All callers changed.
19593 Detect integer overflow in repeat count.
19594 (message_dolog): Don't assume print length fits in 39 bytes.
19595 (display_mode_element): Don't assume strlen fits in int.
19597 * termcap.c: Don't assume sizes fit in int and never overflow.
19598 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19599 (gobble_line): Check for size-calculation overflow.
19601 * minibuf.c (Fread_buffer):
19602 * lread.c (intern, intern_c_string):
19603 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19604 Don't assume string length fits in int.
19606 * keyboard.c (parse_tool_bar_item):
19607 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19609 * font.c: Don't assume string length fits in int.
19610 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19611 Use ptrdiff_t, not int.
19612 (font_intern_prop): Don't assume string length fits in int.
19613 Don't assume integer property fits in fixnum.
19614 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19616 * filelock.c: Fix some buffer overrun and integer overflow issues.
19617 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19618 Reformulate so as not to need the command string.
19619 Invoke gzip -cd rather than gunzip, as it's more portable.
19620 (lock_info_type, lock_file_1, lock_file):
19621 Don't assume pid_t and time_t fit in unsigned long.
19622 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19623 (current_lock_owner): Prefer signed type for sizes.
19624 Use memcpy, not strncpy, where memcpy is what is really wanted.
19625 Don't assume (via atoi) that time_t and pid_t fit in int.
19626 Check for time_t and/or pid_t out of range, e.g., via a network share.
19627 Don't alloca where an auto var works fine.
19629 * fileio.c: Fix some integer overflow issues.
19630 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19631 Don't assume string length fits in int.
19632 (directory_file_name): Don't assume string length fits in long.
19633 (make_temp_name): Don't assume pid fits in int, or that its print
19634 length is less than 20.
19636 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19638 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19640 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19642 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19643 We prefer signed integers, even for size calculations.
19645 * emacs.c: Don't assume string length fits in 'int'.
19646 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19647 (main): Don't invoke strlen when not needed.
19649 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19650 (XD_DEBUG_MESSAGE): Don't waste a byte.
19652 * callproc.c (getenv_internal_1, getenv_internal)
19653 (Fgetenv_internal):
19654 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19656 * lread.c (invalid_syntax): Omit length argument.
19657 All uses changed. This doesn't fix a bug, but it simplifies the
19658 code away from its former Hollerith-constant appearance, and it's
19659 one less 'int' to worry about when looking at integer-overflow issues.
19660 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19662 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19663 This didn't break anything, but it didn't help either.
19664 It's confusing to put a bogus integer in a place where the actual
19665 value does not matter.
19666 (LIST_END_P): Remove unused macro and its bogus comment.
19667 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19669 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19670 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19672 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19673 We prefer signed types, and the value cannot exceed the EMACS_INT
19674 range anyway (because otherwise the length would not be representable).
19675 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19676 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19677 This avoids a GCC warning when WIDE_EMACS_INT.
19679 * indent.c (sane_tab_width): New function.
19680 (current_column, scan_for_column, Findent_to, position_indentation)
19681 (compute_motion): Use it. This is just for clarity.
19682 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19684 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19686 * lisp.h (lint_assume): New macro.
19687 * composite.c (composition_gstring_put_cache):
19688 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19690 * editfns.c, insdel.c:
19691 Omit unnecessary forward decls, to simplify future changes.
19693 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19695 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19697 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19698 Use much-faster test for byte-length change.
19699 Don't assume string byte-length fits in 'int'.
19700 Check that character arg fits in 'int'.
19701 (mapcar1): Declare byte as byte, for clarity.
19703 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19705 * fns.c (concat): Catch string overflow earlier.
19706 Do not rely on integer wraparound.
19708 * dispextern.h (struct it.overlay_strings_charpos)
19709 (struct it.selective): Now EMACS_INT, not int.
19710 * xdisp.c (forward_to_next_line_start)
19711 (back_to_previous_visible_line_start)
19712 (reseat_at_next_visible_line_start, next_element_from_buffer):
19713 Don't arbitrarily truncate the value of 'selective' to int.
19715 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19717 * composite.c: Don't truncate sizes to 'int'.
19718 (composition_gstring_p, composition_reseat_it)
19719 (composition_adjust_point): Use EMACS_INT, not int.
19720 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19721 not EMACS_UINT, for indexes.
19723 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19725 * buffer.c: Include <verify.h>.
19726 (struct sortvec.priority, struct sortstr.priority):
19727 Now EMACS_INT, not int.
19728 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19729 (struct sortstr.size, record_overlay_string)
19730 (struct sortstrlist.size, struct sortlist.used):
19731 Don't truncate size to int.
19732 (record_overlay_string): Check for size-calculation overflow.
19733 (init_buffer_once): Check at compile-time, not run-time.
19735 2011-06-22 Jim Meyering <meyering@redhat.com>
19737 Don't leak an XBM-image-sized buffer
19738 * image.c (xbm_load): Free the image buffer after using it.
19740 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19743 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19744 that Sun C diagnosed.
19745 * fns.c (secure_hash): Fix pointer signedness issue.
19746 * intervals.c (static_offset_intervals): New function.
19747 (offset_intervals): Use it.
19749 2011-06-21 Leo Liu <sdl.web@gmail.com>
19752 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19755 * fns.c (secure_hash): Rename from crypto_hash_function and change
19756 the first arg to accept symbols.
19757 (Fsecure_hash): New primitive.
19758 (syms_of_fns): New symbols.
19760 2011-06-20 Deniz Dogan <deniz@dogan.se>
19762 * process.c (Fset_process_buffer): Clarify return value in
19765 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19767 * dispnew.c (add_window_display_history): Use BVAR.
19769 * xdisp.c (debug_method_add): Use BVAR.
19770 (check_window_end, dump_glyph_matrix, dump_glyph)
19771 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19773 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19776 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19777 check till after the cache is created in init_frame_faces.
19779 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19781 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19783 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19785 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19786 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19787 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19789 Improve buffer-overflow checking (Bug#8873).
19790 * fileio.c (Finsert_file_contents):
19791 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19792 Remove the old (too-loose) buffer overflow checks.
19793 They weren't needed, since make_gap checks for buffer overflow.
19794 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19795 The old code merely checked for Emacs fixnum overflow, and relied
19796 on undefined (wraparound) behavior. The new code avoids undefined
19797 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19799 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19800 Tune. Don't use wider integers than needed. Don't use alloca.
19801 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19803 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19805 * insdel.c, lisp.h (buffer_overflow): New function.
19806 (insert_from_buffer_1, replace_range, replace_range_2):
19807 * insdel.c (make_gap_larger):
19808 * editfns.c (Finsert_char):
19809 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19811 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19813 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19815 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19817 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19818 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19820 * fileio.c: Don't assume EMACS_INT fits in off_t.
19821 (emacs_lseek): New static function.
19822 (Finsert_file_contents, Fwrite_region): Use it.
19823 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19825 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19827 * fns.c: Don't overflow int when computing a list length.
19828 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19829 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19830 truncation on 64-bit hosts. Check for QUIT every
19831 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19832 faster and is responsive enough.
19833 (Flength): Report an error instead of overflowing an integer.
19834 (Fsafe_length): Return a float if the value is not representable
19835 as a fixnum. This shouldn't happen except in contrived situations.
19836 (Fnthcdr, Fsort): Don't assume list length fits in int.
19837 (Fcopy_sequence): Don't assume vector length fits in int.
19839 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19840 (header_size, word_size): New constants.
19841 (allocate_vectorlike): Don't check size overflow here.
19842 (allocate_vector): Check it here instead, since this is the only
19843 caller of allocate_vectorlike that could cause overflow.
19844 Check that the new vector's length is representable as a fixnum.
19846 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19847 The previous code was bogus. For example, next_almost_prime (32)
19848 returned 39, which is undesirable as it is a multiple of 3; and
19849 next_almost_prime (24) returned 25, which is a multiple of 5 so
19850 why was the code bothering to check for multiples of 7?
19852 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19854 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19856 Variadic C functions now count arguments with ptrdiff_t.
19857 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19858 Back then I didn't know that the Emacs coding style prefers signed int.
19859 Also, in the meantime I found a few more instances where arguments
19860 were being counted with int, which may truncate counts on 64-bit
19861 machines, or EMACS_INT, which may be unnecessarily wide.
19862 * lisp.h (struct Lisp_Subr.function.aMANY)
19863 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19864 Arg counts are now ptrdiff_t, not size_t.
19865 All variadic functions and their callers changed accordingly.
19866 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19867 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19868 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19869 * callint.c (Fcall_interactively): Check arg count for overflow,
19870 to avoid potential buffer overrun. Use signed char, not 'int',
19871 for 'varies' array, so that we needn't bother to check its size
19872 calculation for overflow.
19873 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19874 * eval.c (apply_lambda):
19875 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19876 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19877 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19879 * callint.c (Fcall_interactively): Don't use index var as event count.
19881 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19882 * mem-limits.h (SIZE): Remove; no longer used.
19884 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19886 Remove unnecessary casts.
19887 * xterm.c (x_term_init):
19888 * xfns.c (x_set_border_pixel):
19889 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19890 These aren't needed now that we assume ANSI C.
19892 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19893 It's more likely to cause problems (due to unsigned overflow)
19896 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19898 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19900 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19902 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19904 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19906 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19908 GLYPH_CODE_FACE returns EMACS_INT, not int.
19909 * dispextern.h (merge_faces):
19910 * xfaces.c (merge_faces):
19911 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19912 Don't assume EMACS_INT fits in int.
19914 * character.h (CHAR_VALID_P): Remove unused parameter.
19915 * fontset.c, lisp.h, xdisp.c: All uses changed.
19917 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19919 * fns.c (concat): Minor tuning based on overflow analysis.
19920 This doesn't fix any bugs. Use int to hold character, instead
19921 of constantly refetching from Emacs object. Use XFASTINT, not
19922 XINT, for value known to be a character. Don't bother comparing
19923 a single byte to 0400, as it's always less.
19925 * floatfns.c (Fexpt):
19926 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19928 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19931 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19933 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19934 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19935 incorrectly succeed when S was a string, because 4294967386 was
19936 truncated before it was used.
19938 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19939 Otherwise, an out-of-range integer could cause undefined behavior
19942 * composite.c: Use int, not EMACS_INT, for characters.
19943 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19944 EMACS_INT, for values that are known to be in character range.
19945 This doesn't fix any bugs but is the usual style inside Emacs and
19946 may generate better code on 32-bit machines.
19948 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19949 This is for reasons similar to the recent CHAR_STRING fix.
19950 * charset.c (Fencode_char): Check that character arg is actually
19951 a character. Pass an int to ENCODE_CHAR.
19952 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19953 wider than 'int', as a compile-time check to prevent future regressions
19956 * character.c (char_string): Remove unnecessary casts.
19958 Make sure a 64-bit char is never passed to CHAR_STRING.
19959 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19960 by silently ignoring the top 32 bits, allowing some values
19961 that were far too large to be valid characters.
19962 * character.h: Include <verify.h>.
19963 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19964 arguments are no wider than unsigned, as a compile-time check
19965 to prevent future regressions in this area.
19967 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19968 (Fsubst_char_in_region):
19970 * xdisp.c (decode_mode_spec_coding):
19971 Adjust to CHAR_STRING's new requirement.
19972 * editfns.c (Finsert_char, Fsubst_char_in_region):
19973 * fns.c (concat): Check that character args are actually
19974 characters. Without this test, these functions did the wrong
19975 thing with wildly out-of-range values on 64-bit hosts.
19977 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19978 These casts should not be needed on 32-bit hosts, either.
19979 * keyboard.c (read_char):
19980 * lread.c (Fload): Remove casts to unsigned.
19982 * lisp.h (UNSIGNED_CMP): New macro.
19983 This fixes comparison bugs on 64-bit hosts.
19984 (ASCII_CHAR_P): Use it.
19985 * casefiddle.c (casify_object):
19986 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19987 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19988 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19989 * dispextern.h (FACE_FROM_ID):
19990 * keyboard.c (read_char): Use UNSIGNED_CMP.
19992 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,

20041 when a (possibly-narrower) signed value would do just as well.
20042 We prefer using signed arithmetic, to avoid comparison confusion.
20044 * alloc.c: Catch some string size overflows that we were missing.
20045 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20046 for convenience in STRING_BYTES_MAX.

20053 and ptrdiff_t and EMACS_INT are both 64 bits.
20055 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20056 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

20634 instead of using explicit *_CHAR codes.
20635 (bidi_resolve_explicit, bidi_resolve_weak):

20644 (bidi_level_of_next_char): Don't try to lookup the cache for the
20645 next/previous character if nothing is cached there yet, or if we
20646 were just reseat()'ed to a new position.
20648 * xdisp.c (set_cursor_from_row): Set start and stop points
20649 according to the row's direction when priming the loop that looks
20650 for the glyph on which to display cursor.

20652 (display_prop_intangible_p): Reimplement to call
20653 handle_display_spec instead of single_display_spec_intangible_p.
20654 Accept 3 additional arguments needed by handle_display_spec.
20655 This fixes incorrect cursor motion across display property with complex
20656 values: lists, `(when COND...)' forms, etc.

20658 lists with the argument STRING its top-level element.
20659 (display_prop_string_p): Fix the condition for processing a
20660 property that is a list to be consistent with handle_display_spec.

20662 last portion of handle_display_prop.
20663 (compute_display_string_pos): Accept additional argument
20664 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20665 value of a `display' property is a "replacing spec".
20666 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20667 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20668 the display property, but just return a value indicating whether
20669 the display property will replace the characters it covers.
20670 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20671 frame_window_p members of struct bidi_it.
20672 (compute_display_string_pos, compute_display_string_end):

20678 * keyboard.c (adjust_point_for_property): Adjust the call to
20679 display_prop_intangible_p to its new signature.

20695 All callers changed. (Bug#8762)
20697 * gnutls.c: Use Emacs's memory allocators.
20698 Without this change, the gnutls library would invoke malloc etc.
20699 directly, which causes problems on non-SYNC_INPUT hosts, and which
20700 runs afoul of improving memory_full behavior. (Bug#8761)
20701 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20702 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20703 xfree instead of the default malloc, realloc, free.
20704 (Fgnutls_boot): No need to check for memory allocation failure,
20705 since xmalloc does that for us.
20707 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

20727 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20728 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20729 * alloc.c (allocate_vectorlike):
20730 Check for overflow in vector size calculations.
20731 * ccl.c (ccl_driver):
20732 Check for overflow when converting EMACS_INT to int.

20734 need to be updated by these changes.
20735 * fns.c (make_hash_table, maybe_resize_hash_table):
20736 Check for integer overflow with large hash tables.
20737 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20738 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20739 (SXHASH_REDUCE): New macro.
20740 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20741 Use it instead of discarding useful hash info with large hash values.
20742 (sxhash_float): New function.
20743 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20744 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20745 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20746 Rewrite to use FIXNUM_BITS, as this simplifies things.
20747 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20748 Adjust signatures to match updated version of code.
20749 (consing_since_gc): Now EMACS_INT, since a single hash table can
20750 use more than INT_MAX bytes.

20799 Make it possible to run ./temacs.
20801 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20802 syms_of_callproc does the same thing. Remove test for
20803 "initialized", do it in the caller.
20804 * emacs.c (main): Avoid calling set_initial_environment when dumping.

20863 * fns.c (to_uchar): Define.
20864 (crypto_hash_function): Use it to convert some newly-signed
20865 variables to unsigned, to avoid sign-extension bugs. For example,
20866 without this change, (md5 "truc") would evaluate to
20867 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20868 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20869 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20871 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20873 Integer overflow fixes.
20875 * dbusbind.c: Serial number integer overflow fixes.
20876 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20877 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20878 to hold a serial number that is too large for a fixnum.
20879 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20880 Check for serial numbers out of range. Decode any serial number
20881 that was so large that it became a float. (Bug#8722)
20883 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20884 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20885 Use XFASTINT rather than XUINT when numbers are nonnegative.
20886 (xd_append_arg, Fdbus_method_return_internal):
20887 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20888 arguments, check that Lisp number is nonnegative, rather than
20889 silently wrapping negative numbers around. (Bug#8722)
20890 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20893 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20895 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20897 ccl: Add integer overflow checks.
20898 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20899 (IN_INT_RANGE): New macros.
20900 (ccl_driver): Use them to check for integer overflow when
20901 decoding a CCL program. Many of the new checks are whether XINT (x)
20902 fits in int; it doesn't always, on 64-bit hosts. The new version
20903 doesn't catch all possible integer overflows, but it's an
20904 improvement. (Bug#8719)
20906 * alloc.c (make_event_array): Use XINT, not XUINT.
20907 There's no need for unsigned here.
20909 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20910 This follows up to the 2011-05-06 change that substituted uintptr_t
20911 for EMACS_INT. This case wasn't caught back then.
20913 Rework Fformat to avoid integer overflow issues.
20914 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20915 now (part of C89). Include <verify.h>.
20916 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20917 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20918 (Fformat): Avoid the prepass trying to compute sizes; it was only
20919 approximate and thus did not catch overflow reliably. Instead, walk
20920 through the format just once, formatting and computing sizes as we go,
20921 checking for integer overflow at every step, and allocating a larger
20922 buffer as needed. Keep track separately whether the format is
20923 multibyte. Keep only the most-recently calculated precision, rather
20924 than them all. Record whether each argument has been converted to
20925 string. Use EMACS_INT, not int, for byte and char and arg counts.
20926 Support field widths and precisions larger than INT_MAX. Avoid
20927 sprintf's undefined behavior with conversion specifications such as %#d
20928 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20929 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20930 formatting out-of-range floating point numbers with int
20931 formats. (Bug#8668)
20933 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20935 * data.c: Avoid integer truncation in expressions involving floats.
20936 * data.c: Include <intprops.h>.
20937 (arith_driver): When there's an integer overflow in an expression
20938 involving floating point, convert the integers to floating point
20939 so that the resulting value does not suffer from catastrophic
20940 integer truncation. For example, on a 64-bit host (* 4
20941 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20942 Do not rely on undefined behavior after integer overflow.
20944 merge count_size_as_multibyte, parse_str_to_multibyte
20945 * character.c, character.h (count_size_as_multibyte):
20946 Rename from parse_str_to_multibyte; all uses changed.
20947 Check for integer overflow.
20948 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20949 since it's now a duplicate of the other. This is more of
20950 a character than a buffer op, so better that it's in character.c.
20951 * fns.c, print.c: Adjust to above changes.
20953 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20955 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20957 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20959 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20960 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20961 (x_clipboard_manager_save): Now static.
20962 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20964 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20965 (crypto_hash_function): Now static.
20966 Fix pointer signedness problems. Avoid unnecessary initializations.
20968 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20970 * termhooks.h (Vselection_alist): Make it terminal-local.
20972 * terminal.c (create_terminal): Initialize it.
20974 * xselect.c: Support for clipboard managers.
20975 (Vselection_alist): Move to termhooks.h as terminal-local var.
20976 (LOCAL_SELECTION): New macro.
20977 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20978 (symbol_to_x_atom): Remove gratuitous arg.
20979 (x_handle_selection_request, lisp_data_to_selection_data)
20980 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20981 (x_own_selection, x_get_local_selection, x_convert_selection):
20982 New arg, specifying work frame. Use terminal-local Vselection_alist.
20983 (some_frame_on_display): Delete unused function.
20984 (Fx_own_selection_internal, Fx_get_selection_internal)
20985 (Fx_disown_selection_internal, Fx_selection_owner_p)
20986 (Fx_selection_exists_p): New optional frame arg.
20987 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20988 (x_handle_selection_clear): Don't treat other terminals with the
20989 same keyboard specially. Use the terminal-local Vselection_alist.
20990 (x_clear_frame_selections): Use Frun_hook_with_args.
20992 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20994 * xterm.h: Add support for those atoms.
20996 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20998 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20999 (converted_selections, conversion_fail_tag): New global variables.
21000 (x_selection_request_lisp_error): Free the above.
21001 (x_get_local_selection): Remove unnecessary code.
21002 (x_reply_selection_request): Args changed; handle arbitrary array
21003 of converted selections stored in converted_selections.
21004 Separate the XChangeProperty and SelectionNotify steps.
21005 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21006 (x_convert_selection): New function.
21007 (x_handle_selection_event): Simplify.
21008 (x_get_foreign_selection): Don't ignore incoming requests while
21009 waiting for an answer; this will fail when we implement
21010 SAVE_TARGETS, and seems unnecessary anyway.
21011 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21012 (Vx_sent_selection_functions): Doc fix.
21014 2011-05-26 Leo Liu <sdl.web@gmail.com>
21016 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21018 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21020 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21022 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21023 for fringe update if it has periodic bitmap.
21024 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21025 and fringe_bitmap_periodic_p.
21027 * fringe.c (get_fringe_bitmap_data): New function.
21028 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21029 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21030 row. Mark glyph row for fringe update if periodicity changed.
21032 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21033 for fringe update unless it has periodic bitmap.
21035 2011-05-25 Kenichi Handa <handa@m17n.org>
21037 * xdisp.c (get_next_display_element): Set correct it->face_id for
21038 a static composition.
21040 2011-05-24 Leo Liu <sdl.web@gmail.com>
21043 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21045 * fns.c (crypto_hash_function, Fsha1): New function.
21046 (Fmd5): Use crypto_hash_function.
21047 (syms_of_fns): Add Ssha1.
21049 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21051 * gnutls.c: Remove unused macros.
21052 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21053 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21054 Remove macros that are defined and never used.
21055 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21057 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21059 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21060 (Fx_get_selection_internal): Minor cleanup.
21061 (Fx_own_selection_internal): Rename arguments for consistency with
21064 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21066 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21068 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21070 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21072 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21074 * dispnew.c (scrolling_window): Don't exclude the case that the
21075 last enabled row in the desired matrix touches the bottom boundary.
21077 2011-05-21 Glenn Morris <rgm@gnu.org>
21079 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21080 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21081 and add some more files.
21083 2011-05-20 Eli Zaretskii <eliz@gnu.org>
21085 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21086 report_file_error introduced by the change from 2011-05-07.
21088 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21090 * systime.h (Time): Define only if emacs is defined.
21091 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21092 where the include path doesn't have X11/X.h by default. See
21093 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21095 2011-05-20 Kenichi Handa <handa@m17n.org>
21097 * composite.c (find_automatic_composition): Fix previous change.
21099 2011-05-20 Glenn Morris <rgm@gnu.org>
21101 * lisp.mk: New file, split from Makefile.in.
21102 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21103 (shortlisp): Remove.
21104 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21106 2011-05-19 Glenn Morris <rgm@gnu.org>
21108 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21109 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21110 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21111 (lisp): Set the order to that of loadup.el.
21112 (shortlisp): Make it a copy of $lisp.
21113 (SOME_MACHINE_LISP): Remove.
21114 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21115 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21117 2011-05-18 Kenichi Handa <handa@m17n.org>
21119 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21120 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21121 (find_automatic_composition): Mostly rewrite for efficiency.
21123 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21125 * makefile.w32-in: Update dependencies.
21127 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21129 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21130 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21132 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21134 Fix some integer overflow issues, such as string length overflow.
21136 * insdel.c (count_size_as_multibyte): Check for string overflow.
21138 * character.c (lisp_string_width): Check for string overflow.
21139 Use EMACS_INT, not int, for string indexes and lengths; in
21140 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21141 the resulting string length overflows an EMACS_INT; instead,
21142 report a string overflow if no precision given. When checking for
21143 precision exhaustion, use a check that cannot possibly have
21144 integer overflow. (Bug#8675)
21145 * character.h (lisp_string_width): Adjust to new signature.
21147 * alloc.c (string_overflow): New function.
21148 (Fmake_string): Use it. This doesn't change behavior, but saves
21149 a few bytes and will simplify future changes.
21150 * character.c (string_escape_byte8): Likewise.
21151 * lisp.h (string_overflow): New decl.
21153 Fixups, following up to the user-interface timestamp change.
21154 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21155 for UI timestamps, instead of unsigned long.
21156 * msdos.c (mouse_get_pos): Likewise.
21157 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21158 * w32gui.h (Time): Define by including "systime.h" rather than by
21159 declaring it ourselves. (Bug#8664)
21161 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21162 * image.c (clear_image_cache): Likewise.
21164 * term.c (term_mouse_position): Don't assume time_t wraparound.
21166 Be more systematic about user-interface timestamps.
21167 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21168 and sometimes 'EMACS_UINT', to represent these timestamps.
21169 This change causes it to use 'Time' uniformly, as that's what X uses.
21170 This makes the code easier to follow, and makes it easier to catch
21171 integer overflow bugs such as Bug#8664.
21172 * frame.c (Fmouse_position, Fmouse_pixel_position):
21173 Use Time, not unsigned long, for user-interface timestamps.
21174 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21175 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21176 * keyboard.h (last_event_timestamp): Likewise.
21177 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21178 * menu.h (xmenu_show): Likewise.
21179 * term.c (term_mouse_position): Likewise.
21180 * termhooks.h (struct input_event.timestamp): Likewise.
21181 (struct terminal.mouse_position_hook): Likewise.
21182 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21183 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21184 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21185 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21186 what it was before.
21187 * menu.h, termhooks.h: Include "systime.h", for Time.
21189 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21190 Don't assume that the difference between two unsigned long values
21191 can fit into an integer. At this point, we know button_down_time
21192 <= event->timestamp, so the difference must be nonnegative, so
21193 there's no need to cast the result if double-click-time is
21194 nonnegative, as it should be; check that it's nonnegative, just in
21195 case. This bug is triggered when events are more than 2**31 ms
21196 apart (about 25 days). (Bug#8664)
21198 * xselect.c (last_event_timestamp): Remove duplicate decl.
21199 (x_own_selection): Remove needless cast to unsigned long.
21201 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21202 that always fit in int. Use a sentinel instead of a counter, to
21203 avoid a temp and to allay GCC's concerns about possible int overflow.
21204 * frame.h (struct frame): Use int for menu_bar_items_used
21205 instead of EMACS_INT, since it always fits in int.
21207 * menu.c (grow_menu_items): Check for int overflow.
21209 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21211 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21212 Before, the code was not consistent. These values cannot exceed
21213 2**31 - 1 so there's no need to make them unsigned.
21214 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21215 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21216 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21218 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21220 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21221 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21222 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21223 presumably because the widths might not match.
21225 * window.c (size_window): Avoid needless test at loop start.
21227 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21229 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21231 2011-05-12 Drew Adams <drew.adams@oracle.com>
21233 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21235 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21237 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21238 `width' to `bar_area_x' and `bar_area_width', respectively.
21239 (x_scroll_run): Take account of fringe background extension.
21241 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21242 Rename local vars `left' and `width' to `bar_area_x' and
21243 `bar_area_width', respectively.
21244 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21245 background extension.
21247 2011-05-10 Jim Meyering <meyering@redhat.com>
21249 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21251 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21253 * image.c (Finit_image_library): Return t for built-in image types,
21254 like pbm and xbm. (Bug#8640)
21256 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21258 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21260 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21262 * w32console.c (Fset_screen_color): Doc fix.
21263 (Fget_screen_color): New function.
21264 (syms_of_ntterm): Defsubr it.
21266 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21267 unlink the temporary file if Fcall_process didn't create it in the
21269 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21270 child process will be redirected to a file specified with `:file'.
21271 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21272 cue to call_process_cleanup not to close that handle.
21274 2011-05-07 Ben Key <bkey76@gmail.com>
21276 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21277 one of two shell specific rules, either bootstrap-temacs-CMD or
21278 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21279 to the previous implementation of the bootstrap-temacs rule.
21280 The bootstrap-temacs-CMD rule is similar to the previous
21281 implementation of the bootstrap-temacs rule except that it
21282 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21285 These changes, along with some changes to nt/configure.bat,
21286 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21287 earlier fix to add support for --cflags and --ldflags options
21288 that include quotes so that it works whether make uses cmd or
21291 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21293 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21294 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21296 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21297 a string. Handle both cases.
21298 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21299 (Fdbus_register_method): Use Qinvalid_function.
21301 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21303 * makefile.w32-in: Update dependencies.
21304 (LISP_H): Add inttypes.h and stdin.h.
21305 (PROCESS_H): Add unistd.h.
21307 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21309 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21310 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21312 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21314 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21316 * term.c (vfatal): Remove stray call to va_end.
21317 It's not needed and the C Standard doesn't allow it here anyway.
21319 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21320 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21322 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21325 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21327 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21329 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21331 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21333 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21335 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21336 * charset.c (Fdefine_charset_internal): Don't initialize
21337 charset.code_space[15]. The value was garbage, on hosts with
21338 32-bit int (Bug#8600).
21340 * lread.c (read_integer): Be more consistent with string-to-number.
21341 Use string_to_number to do the actual conversion; this avoids
21342 rounding errors and fixes some other screwups. Without this fix,
21343 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21344 (digit_to_number): Move earlier, for benefit of read_integer.
21345 Return -1 if the digit is out of range for the base, -2 if it is
21346 not a digit in any supported base. (Bug#8602)
21348 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21350 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21351 to match comment at start of function. This also removes a
21352 GCC warning about overflow in a 32+64-bit port.
21354 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21356 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21357 Reported by Stefan Monnier in
21358 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21359 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21360 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21362 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21363 (EMACS_UINTPTR): Likewise, with uintptr_t.
21365 * lisp.h: Prefer 64-bit EMACS_INT if available.
21366 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21367 on 32-bit hosts that have 64-bit int, so that they can access
21369 However, temporarily disable this change unless the temporary
21370 symbol WIDE_EMACS_INT is defined.
21372 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21374 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21375 This removes an assumption that EMACS_INT and long are the same
21376 width as pointers. The assumption is true for Emacs porting targets
21377 now, but we want to make other targets possible.
21378 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21379 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21380 In the rest of the code, change types of integers that hold casted
21381 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21382 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21383 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21384 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21385 No need to cast type when ORing.
21386 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21387 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21388 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21389 assume EMACS_INT is the same width as char *.
21390 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21391 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21392 Remove no-longer-needed casts.
21393 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21394 (xg_tool_bar_help_callback, xg_make_tool_item):
21395 Use EMACS_INTPTR to hold an integer
21396 that will be cast to void *; this can avoid a GCC warning
21397 if EMACS_INT is not the same width as void *.
21398 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21399 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21400 (current_message_1, set_message_1):
21401 Use a local to convert to proper width without a cast.
21402 * xmenu.c (dialog_selection_callback): Likewise.
21404 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21405 Also, don't assume VALBITS / RAND_BITS is less than 5,
21406 and don't rely on undefined behavior when shifting a 1 left into
21408 * lisp.h (get_random): Change signature to match.
21410 * lread.c (hash_string): Use size_t, not int, for hash computation.
21411 Normally we prefer signed values; but hashing is special, because
21412 it's better to use unsigned division on hash table sizes so that
21413 the remainder is nonnegative. Also, size_t is the natural width
21414 for hashing into memory. The previous code used 'int', which doesn't
21415 retain enough info to hash well into very large tables.
21416 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21418 * dbusbind.c: Don't possibly lose pointer info when converting.
21419 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21420 Use XPNTR rather than XHASH, so that the high-order bits of
21421 the pointer aren't lost when converting through void *.
21423 * eval.c (Fautoload): Don't double-shift a pointer.
21425 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21427 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21429 * gnutls.c (DEF_GNUTLS_FN):
21430 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21432 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21434 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21437 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21439 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21440 New version that can reserve upto 2GB of heap space.
21442 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21444 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21446 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21448 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21449 `gnutls_certificate_set_x509_key_file'.
21451 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21453 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21454 Update dependencies.
21456 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21458 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21459 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21460 Remove unused parameter `fildes'.
21461 * process.c (read_process_output, send_process): Don't pass it.
21463 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21465 Fix previous change: the library cache is defined in w32.c.
21466 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21467 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21469 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21471 Implement dynamic loading of GnuTLS on Windows.
21473 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21474 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21475 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21478 * gnutls.c (Qgnutls_dll): Define.
21479 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21480 (gnutls_*): Declare function pointers.
21481 (init_gnutls_functions): New function to initialize function pointers.
21482 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21483 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21484 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21485 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21486 (emacs_gnutls_write, emacs_gnutls_read)
21487 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21488 (Fgnutls_available_p): New function.
21489 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21490 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21491 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21493 * image.c: Include w32.h.
21494 (Vimage_type_cache): Delete.

21499 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21501 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21502 (w32_delayed_load): Move from image.c. When loading a library, record
21503 its filename in the :loaded-from property of the library id.
21504 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21505 Initialize and staticpro them.
21506 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21508 * process.c: Include lisp.h before w32.h, not after.
21509 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21510 instead of gnutls_record_check_pending.
21512 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21514 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21516 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21517 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21520 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21522 * xterm.c (x_set_frame_alpha): Do not set property on anything
21523 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21525 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21527 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21529 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21531 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21532 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21541 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21543 * callproc.c: Indentation fixup.
21545 * sysdep.c (wait_for_termination_1): Make static.
21546 (wait_for_termination, interruptible_wait_for_termination):
21547 Move after wait_for_termination_1.
21549 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21551 * sysdep.c (interruptible_wait_for_termination): New function
21552 which is like wait_for_termination, but allows keyboard
21555 * callproc.c (Fcall_process): Add (:file "file") as an option for
21557 (Fcall_process_region): Ditto.
21559 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21561 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21562 rather than `XVECTOR (FOO)->size'.
21564 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21565 inttypes.h, as a gnulib replacement is used if it not available in
21568 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21570 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21571 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21572 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21574 * coding.c (coding_alloc_by_realloc): Error out if destination
21575 will grow beyond MOST_POSITIVE_FIXNUM.
21576 (decode_coding_emacs_mule): Abort if there isn't enough place in
21577 charbuf for the composition carryover bytes. Reserve an extra
21578 space for up to 2 characters produced in a loop.
21579 (decode_coding_iso_2022): Abort if there isn't enough place in
21580 charbuf for the composition carryover bytes.
21582 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21584 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21585 aborting when %lld or %lll format is passed.
21586 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21587 %llo or %llx format is passed. (Bug#8545)
21589 * window.c (window_scroll_line_based): Use a marker instead of
21590 simple variables to record original value of point. (Bug#7952)
21592 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21593 produced by %s or %c overflows available buffer space. (Bug#8545)
21595 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21597 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21598 (SIZE_MAX): Move defn after all includes, as they might #define it.
21600 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21602 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21604 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21606 * keyboard.c (Qdelayed_warnings_hook): Define.
21607 (command_loop_1): Run `delayed-warnings-hook'
21608 if Vdelayed_warnings_list is non-nil.
21609 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.

21612 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21614 * doprnt.c (doprnt): Don't return value smaller than the buffer
21615 size if the message was truncated. (Bug#8545).
21617 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21619 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21620 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21622 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21624 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21626 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21628 * makefile.w32-in: Update dependencies.
21630 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21632 Improve `doprnt' and its usage. (Bug#8545)
21633 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21634 `format_end'. Remove support for %l as a conversion specifier.
21635 Don't use xrealloc. Improve diagnostics when the %l size modifier
21636 is used. Update the commentary.
21638 * eval.c (verror): Simplify calculation of size_t.
21640 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21643 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21645 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21648 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21650 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21651 This makes this file independent of the recent pseudovector change.
21653 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21655 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21657 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21658 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21659 Remove unused local.
21660 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21662 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21663 GCC 4.6.0 optimizes based on type-based alias analysis.
21664 For example, if b is of type struct buffer * and v of type struct
21665 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21666 != &v->size, and therefore "v->size = 1; b->size = 2; return
21667 v->size;" must therefore return 1. This assumption is incorrect
21668 for Emacs, since it type-puns struct Lisp_Vector * with many other
21669 types. To fix this problem, this patch adds a new type struct
21670 vectorlike_header that documents the constraints on layout of vectors
21671 and pseudovectors, and helps optimizing compilers not get fooled
21672 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21673 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21674 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21676 (XSETPVECTYPE): Rewrite in terms of new macro.
21677 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21678 This is a bit clearer, and further avoids the possibility of
21679 undesirable aliasing.
21680 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21681 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21682 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21683 since Lisp_Subr is a special case (no "next" field).
21684 (ASIZE): Now uses header.size rather than size.
21685 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21686 to avoid the hassle of writing XVECTOR (foo)->header.size.
21687 (struct vectorlike_header): New type.
21688 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21689 object, to help avoid aliasing.
21690 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21691 (SUBRP): Likewise, since Lisp_Subr is a special case.
21692 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21693 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21694 (struct Lisp_Hash_Table): Combine first two members into a single
21695 struct vectorlike_header member. All uses of "size" and "next" members
21696 changed to be "header.size" and "header.next".
21697 * buffer.h (struct buffer): Likewise.
21698 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21699 * frame.h (struct frame): Likewise.
21700 * process.h (struct Lisp_Process): Likewise.
21701 * termhooks.h (struct terminal): Likewise.
21702 * window.c (struct save_window_data, struct saved_window): Likewise.
21703 * window.h (struct window): Likewise.
21704 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21705 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21706 * buffer.c (init_buffer_once): Likewise.
21707 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21709 * process.c (Fformat_network_address): Use local var for size,
21712 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21714 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21715 * data.c (atof): Remove decl; no longer used or needed.
21716 (digit_to_number): Move to lread.c.
21717 (Fstring_to_number): Use new string_to_number function, to be
21718 consistent with how the Lisp reader treats infinities and NaNs.
21719 Do not assume that floating-point numbers represent EMACS_INT
21720 without losing information; this is not true on most 64-bit hosts.
21721 Avoid double-rounding errors, by insisting on integers when
21722 parsing non-base-10 numbers, as the documentation specifies.
21723 * lisp.h (string_to_number): New decl, replacing ...
21724 (isfloat_string): Remove.
21725 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21726 (read1): Do not accept +. and -. as integers; this
21727 appears to have been a coding error. Similarly, do not accept
21728 strings like +-1e0 as floating point numbers. Do not report
21729 overflow for integer overflows unless the base is not 10 which
21730 means we have no simple and reliable way to continue.
21731 Break out the floating-point parsing into a new
21732 function string_to_number, so that Fstring_to_number parses
21733 floating point numbers consistently with the Lisp reader.
21734 (digit_to_number): Move here from data.c. Make it static inline.
21735 (E_CHAR, EXP_INT): Remove, replacing with ...
21736 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21737 (string_to_number): New function, replacing isfloat_string.
21738 This function checks for valid syntax and produces the resulting
21739 Lisp float number too. Rework it so that string-to-number
21740 no longer mishandles examples like "1.0e+". Use strtoumax,
21741 so that overflow for non-base-10 numbers is reported only when
21742 there's no portable and simple way to convert to floating point.
21744 * textprop.c (set_text_properties_1): Rewrite for clarity,
21745 and to avoid GCC warning about integer overflow.
21747 * intervals.h (struct interval): Use EMACS_INT for members
21748 where EMACS_UINT might cause problems. See
21749 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21750 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21751 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21753 (offset_intervals): Tell GCC not to worry about length overflow
21754 when negating a negative length.
21756 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21757 (overrun_check_free): Likewise.
21759 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21760 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21763 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21764 (gnutls_make_error): Rename local to avoid shadowing.
21765 (gnutls_emacs_global_deinit): ifdef out; not used.
21766 (Fgnutls_boot): Use const for pointer to readonly storage.
21767 Comment out unused local. Fix pointer signedness problems.
21769 * lread.c (openp): Don't stuff size_t into an 'int'.
21770 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21771 about possible signed overflow.
21773 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21774 (GDK_KEY_g): Don't define if already defined.
21775 (xg_prepare_tooltip): Avoid pointer signedness problem.
21776 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21778 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21779 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21781 * xfns.c (Fx_window_property): Simplify a bit,
21782 to make a bit faster and to avoid GCC 4.6.0 warning.
21783 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21785 * fns.c (internal_equal): Don't assume size_t fits in int.
21787 * alloc.c (compact_small_strings): Tighten assertion a little.
21789 Replace pEd with more-general pI, and fix some printf arg casts.
21790 * lisp.h (pI): New macro, generalizing old pEd macro to other
21791 conversion specifiers. For example, use "...%"pI"d..." rather
21792 than "...%"pEd"...".
21793 (pEd): Remove. All uses replaced with similar uses of pI.
21794 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21795 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21796 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21797 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21798 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21799 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21800 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21802 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21803 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21804 * print.c (safe_debug_print, print_object): Likewise.
21805 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21807 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21808 avoiding the 0 flag, which is not portable.
21809 * process.c (Fmake_network_process): Use pI to avoid cast.
21810 * region-cache.c (pp_cache): Likewise.
21811 * xdisp.c (decode_mode_spec): Likewise.
21812 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21813 behavior on 64-bit hosts with printf arg.
21814 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21815 (x_stop_queuing_selection_requests): Likewise.
21816 (x_get_window_property): Don't truncate byte count to an 'int'
21819 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21820 here, since it parses constructs like leading '-' and spaces,
21821 which are not wanted; and it overflows with large numbers.
21822 Instead, simply match F[0-9]+, which is what is wanted anyway.
21824 * alloc.c: Remove unportable assumptions about struct layout.
21825 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21826 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21827 (allocate_vectorlike, make_pure_vector): Use the new macros,
21828 plus offsetof, to remove unportable assumptions about struct layout.
21829 These assumptions hold on all porting targets that I know of, but
21830 they are not guaranteed, they're easy to remove, and removing them
21831 makes further changes easier.
21833 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21834 This doesn't fix a bug but makes the code clearer.
21835 (string_overrun_cookie): Now const. Use initializers that
21836 don't formally overflow signed char, to avoid warnings.
21837 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21838 can cause Emacs to crash when string overrun checking is enabled.
21839 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21840 multiple of sizeof (EMACS_INT); it need not be, if
21841 alignof(EMACS_INT) < sizeof (EMACS_INT).
21842 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21844 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21851 supposed to be handshaking. (Bug#8556)
21852 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21854 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

21871 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21873 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21874 "cast to pointer from integer of different size".
21876 Improve doprnt and its use in verror. (Bug#8545)
21877 * doprnt.c (doprnt): Document the set of format control sequences
21878 supported by the function. Use SAFE_ALLOCA instead of always
21881 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21882 is one byte too soon. Don't use xrealloc; instead xfree and
21885 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21887 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21890 * gnutls.c: Renamed global_initialized to
21891 gnutls_global_initialized. Added internals for the
21892 :verify-hostname-error, :verify-error, and :verify-flags
21893 parameters of `gnutls-boot' and documented those parameters in the
21894 docstring. Start callback support.
21895 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21896 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21970 (SIZE_MAX): New macro.
21971 (doprnt): Return a size_t value. 2nd arg is now size_t.
21972 Many local variables are now size_t instead of int or unsigned.
21973 Improve overflow protection. Support `l' modifier for integer
21974 conversions. Support %l conversion. Don't assume an EMACS_INT
21975 argument for integer conversions and for %c.
21977 * lisp.h (doprnt): Restore prototype.
21979 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21980 $(SRC)/character.h.
21982 * Makefile.in (base_obj): Add back doprnt.o.
21984 * deps.mk (doprnt.o): Add back prerequisites.
21985 (callint.o): Depend on character.h.
21987 * eval.c (internal_lisp_condition_case): Include the handler
21988 representation in the error message.

21994 * callint.c (Fcall_interactively): When displaying error message
21995 about invalid control letter, pass the character's codepoint, not
21996 a pointer to its multibyte form. Improve display of the character
21997 in octal and display also its hex code.
21999 * character.c (char_string): Use %x to display the (unsigned)
22000 codepoint of an invalid character, to avoid displaying a bogus
22003 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
22004 `error', not SYMBOL_NAME itself.
22006 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
22007 character arguments to `error'.
22009 * charset.c (check_iso_charset_parameter): Fix incorrect argument
22010 to `error' in error message about FINAL_CHAR argument. Make sure
22011 FINAL_CHAR is a character, and use %c when it is passed as

22082 * dispextern.h (struct redisplay_interface): Rename param
22083 to avoid shadowing.
22084 * termhooks.h (struct terminal): Likewise.
22085 * xterm.c (xembed_send_message): Likewise.
22087 * insdel.c (make_gap_smaller): Define only if
22088 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
22090 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
22093 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
22094 so that we aren't warned about unused symbols.
22096 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
22098 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

22111 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
22113 * xmenu.c (menu_help_callback): Pointer type fixes.

22131 compatible char. Avoid the old compiler warnings about
22132 out-of-range initializers by using, for example, '\xab' rather
22135 * xgselect.c (xgselect_initialize): Check vs interface
22136 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

22201 * nsfont.m: Fixed bugs in ns_get_family and
22202 ns_descriptor_to_entity that were caused by using free to
22203 deallocate memory blocks that were allocated by xmalloc (via
22204 xstrdup). This caused Emacs to crash when compiled with
22205 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
22206 --enable-checking=xmallocoverrun). xfree is now used to
22207 deallocate these memory blocks.

22611 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22613 Make Emacs functions such as Fatom 'static' by default.
22614 This makes it easier for human readers (and static analyzers)
22615 to see whether these functions can be called from other modules.
22616 DEFUN now defines a static function. To make the function external
22617 so that it can be used in other C modules, use the new macro DEFUE.
22618 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22619 (Finit_image_library):
22620 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22621 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22622 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22623 Remove decls, since these functions are now static.
22624 (Funintern, Fget_internal_run_time): New decls, since these functions
22625 were already external.
22627 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22628 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
22629 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
22630 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
22631 * keyboard.c, keymap.c, lread.c:
22632 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
22633 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
22634 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22635 Mark functions with DEFUE instead of DEFUN,
22636 if they are used in other modules.
22637 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22638 decls for now-static functions.
22639 * buffer.h (Fdelete_overlay): Remove decl.
22640 * callproc.c (Fgetenv_internal): Mark as internal.
22641 * composite.c (Fremove_list_of_text_properties): Remove decl.
22642 (Fcomposition_get_gstring): New forward static decl.
22643 * composite.h (Fcomposite_get_gstring): Remove decl.
22644 * dired.c (Ffile_attributes): New forward static decl.
22645 * doc.c (Fdocumntation_property): New forward static decl.
22646 * eval.c (Ffetch_bytecode): New forward static decl.
22647 (Funintern): Remove extern decl; now in .h file where it belongs.
22648 * fileio.c (Fmake_symbolic_link): New forward static decl.
22649 * image.c (Finit_image_library): New forward static decl.
22650 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22651 * intervals.h (Fprevious_property_change):
22652 (Fremove_list_of_text_properties): Remove decls.
22653 * keyboard.c (Fthis_command_keys): Remove decl.
22654 (Fcommand_execute): New forward static decl.
22655 * keymap.c (Flookup_key): New forward static decl.
22656 (Fcopy_keymap): Now static.
22657 * keymap.h (Flookup_key): Remove decl.
22658 * process.c (Fget_process): New forward static decl.
22659 (Fprocess_datagram_address): Mark as internal.
22660 * syntax.c (Fsyntax_table_p): New forward static decl.
22661 (skip_chars): Remove duplicate decl.
22662 * textprop.c (Fprevious_property_change): New forward static decl.
22663 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
22665 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
22666 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
22668 * editfns.c (Fformat): Remove unreachable code.
22670 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22672 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22675 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22677 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22678 when at ZV. (Bug#8487)
22680 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22682 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22684 * keyboard.c (parse_tool_bar_item): Likewise.
22685 * sound.c (sound_cleanup, alsa_close): Likewise.
22686 * termcap.c (tgetent): Likewise.
22687 * xfns.c (x_default_font_parameter): Likewise.
22688 * xsettings.c (read_and_apply_settings): Likewise.
22690 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22691 (overrun_check_free): Protoize.
22693 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22695 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22696 since callers should never pass a negative size.
22697 Change the signature to match that of plain 'read' and 'write'; see
22698 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22699 * lisp.h: Update prototypes of emacs_write and emacs_read.
22701 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22703 * xdisp.c (redisplay_window): Don't try to determine the character
22704 position of the scroll margin if the window start point w->startp
22705 is outside the buffer's accessible region. (Bug#8468)
22707 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22709 Fix write-region and its subroutines for buffers > 2GB.
22710 * fileio.c (a_write, e_write): Modify declaration of arguments and
22711 local variables to support buffers larger than 2GB.
22712 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22714 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22715 argument, local variables, and return value.
22717 * lisp.h: Update prototypes of emacs_write and emacs_read.
22719 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22721 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22723 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22725 Fix more problems found by GCC 4.6.0's static checks.
22727 * xdisp.c (vmessage): Use a better test for character truncation.
22729 * charset.c (load_charset_map): <, not <=, for optimization,
22730 and to avoid potential problems with integer overflow.
22731 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22732 * casetab.c (set_identity, shuffle): Likewise.
22733 * editfns.c (Fformat): Likewise.
22734 * syntax.c (skip_chars): Likewise.
22736 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22737 This also lets GCC 4.6.0 generate slightly better loop code.
22739 * callint.c (Fcall_interactively): <, not <=, for optimization.
22740 (Fcall_interactively): Count the number of arguments produced,
22741 not the number of arguments given. This is simpler and lets GCC
22742 4.6.0 generate slightly better code.
22744 * ftfont.c: Distingish more carefully between FcChar8 and char.
22745 The previous code passed unsigned char * to a functions like
22746 strlen and xstrcasecmp that expect char *, which does not
22747 conform to the C standard.
22748 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22749 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22750 char * when the C standard requires it.
22752 * keyboard.c (read_char): Remove unused var.
22754 * eval.c: Port to Windows vsnprintf (Bug#8435).
22755 Include <limits.h>.
22756 (SIZE_MAX): Define if the headers do not.
22757 (verror): Do not give up if vsnprintf returns a negative count.
22758 Instead, grow the buffer. This ports to Windows vsnprintf, which
22759 does not conform to C99. Problem reported by Eli Zaretskii.
22760 Also, simplify the allocation scheme, by avoiding the need for
22761 calling realloc, and removing the ALLOCATED variable.
22763 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22765 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22766 But keep the doprint source code for now, as we might revamp it
22767 and use it again (Bug#8435).
22768 * lisp.h (doprnt): Remove.
22769 * Makefile.in (base_obj): Remove doprnt.o.
22770 * deps.mk (doprnt.o): Remove.
22772 error: Print 32- and 64-bit integers portably (Bug#8435).
22773 Without this change, on typical 64-bit hosts error ("...%d...", N)
22774 was used to print both 32- and 64-bit integers N, which relied on
22775 undefined behavior.
22776 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22777 * lisp.h (error, verror): Mark as printf-like functions.
22778 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22779 Report overflow in size calculations when allocating printf buffer.
22780 Do not truncate output string at its first null byte.
22781 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22782 Truncate the output at a character boundary, since vsnprintf does not
22784 * charset.c (check_iso_charset_parameter): Convert internal
22785 character to string before calling 'error', since %c now has the
22787 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22788 overflow when computing char to be passed to 'error'. Do not
22789 pass Lisp_Object to 'error'; pass the integer instead.
22790 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22791 formatted with plain %d.
22793 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22795 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22797 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22799 * xterm.c (x_catch_errors): Remove duplicate declaration.
22801 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22803 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22805 2011-04-10 Jim Meyering <meyering@redhat.com>
22807 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22808 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22809 return ssize_t not "int", and use size_t as the buffer length.
22810 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22811 * gnutls.h: Update declarations.
22812 * process.c (read_process_output): Use ssize_t, to match.
22813 (send_process): Likewise.
22815 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22817 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22819 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22821 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22822 Use unsigned char, to match FcChar8 type definition.
22824 * xterm.c (handle_one_xevent):
22825 * xmenu.c (create_and_show_popup_menu):
22826 * xselect.c (x_decline_selection_request)
22827 (x_reply_selection_request): Avoid type-punned deref of X events.
22829 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22831 Fix some uses of `int' instead of EMACS_INT.
22832 * search.c (string_match_1, fast_string_match)
22833 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22834 (scan_buffer, find_next_newline_no_quit)
22835 (find_before_next_newline, search_command, Freplace_match)
22836 (Fmatch_data): Make some `int' variables be EMACS_INT.
22838 * xdisp.c (display_count_lines): 3rd argument and return value now
22839 EMACS_INT. All callers changed.
22840 (pint2hrstr): Last argument is now EMACS_INT.
22842 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22843 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22844 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22845 (decode_coding_utf_16, decode_coding_emacs_mule)
22846 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22847 (decode_coding_ccl, decode_coding_charset)
22848 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22849 (decode_coding_iso_2022, decode_coding_emacs_mule)
22850 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22851 <char_offset, last_offset>: Declare EMACS_INT.

22853 (encode_coding_emacs_mule, encode_invocation_designation)
22854 (encode_designation_at_bol, encode_coding_iso_2022)
22855 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22856 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22858 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22859 (encode_invocation_designation): Last argument P_NCHARS is now
22861 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22862 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22864 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22867 * ccl.c (Fccl_execute_on_string): Declare some variables
22870 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22872 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22874 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22876 * process.c (Fformat_network_address): Doc fix.
22878 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22880 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22882 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22884 * keyboard.c (read_char): Call Lisp function help-form-show,
22885 instead of using internal_with_output_to_temp_buffer.
22886 (Qhelp_form_show): New var.
22887 (syms_of_keyboard): Use DEFSYM macro.
22889 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22891 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22893 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22895 * process.c (Flist_processes): Remove to Lisp.
22896 (list_processes_1): Delete.
22898 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22900 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22902 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22904 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22906 Fix more problems found by GCC 4.6.0's static checks.
22908 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22910 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22912 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22914 * xdisp.c (vmessage): Mark as a printf-like function.
22916 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22918 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22920 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22921 printf-like functions.
22922 (tiff_load): Add casts to remove these marks before passing them
22923 to system-supplied API.
22925 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22927 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22928 This avoids several warnings with gcc -Wstrict-overflow.
22929 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22930 directly, rather than having caller test rule sign. This avoids
22931 some unnecessary tests.
22932 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22933 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22934 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22936 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22937 (xfont_open): Avoid unnecessary tests.
22939 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22941 * composite.h, composite.c (composition_gstring_put_cache):
22942 Use EMACS_INT, not int, for length.

22945 breaking out part of COMPOSITION_DECODE_RULE.
22946 (COMPOSITION_DECODE_RULE): Use it.
22947 * composite.c (get_composition_id): Remove unused local vars,
22948 by using the new macro.
22950 * textprop.c (set_text_properties_1): Change while to do-while,
22951 since the condition is always true at first.
22953 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22954 (interval_deletion_adjustment): Return unsigned value.
22957 * process.c (list_processes_1, create_pty, read_process_output):

22962 (read_process_output): Simplify nbytes computation if buffered.
22964 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
22966 * syntax.c (scan_words): Remove var that was set but not used.
22967 (update_syntax_table): Use unsigned instead of int.
22969 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22970 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22971 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22973 * print.c (print_error_message): Avoid int overflow.
22975 * font.c (font_list_entities): Redo for clarity,
22976 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22978 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22979 (font_score): Avoid potential overflow in diff calculation.
22981 * fns.c (substring_both): Remove var that is set but not used.
22982 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22984 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22986 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22987 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22988 can always succeed if overflow has undefined behavior.
22990 * search.c (boyer_moore, wordify): Remove vars set but not used.
22991 (wordify): Omit three unnecessary tests.
22993 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22994 All callers changed. This avoids the need for an unused var.
22996 * casefiddle.c (casify_region): Remove var that is set but not used.
22998 * dired.c (file_name_completion): Remove var that is set but not used.
23000 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23002 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23003 (Finsert_file_contents): Remove unnecessary code checking fd.
23005 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23006 Check for integer overflow on size calculations.
23008 * buffer.c (Fprevious_overlay_change): Remove var that is set
23011 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23012 Remove vars that are set but not used.
23013 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23014 (timer_check_2): Mark vars as initialized.
23016 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23018 * image.c (lookup_image): Remove var that is set but not used.
23019 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23021 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23022 that are set but not used.
23024 * xfns.c (make_invisible_cursor): Don't return garbage
23025 if XCreateBitmapFromData fails (Bug#8410).
23027 * xselect.c (x_get_local_selection, x_handle_property_notify):
23028 Remove vars that are set but not used.
23030 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23031 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23033 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23034 Remove var that is set but not used.
23035 (scroll_bar_windows_size): Now size_t, not int.
23036 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23037 Check for overflow.
23039 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23040 (map_tty_color) [!defined MSDOS]: Likewise.
23042 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23044 * coding.c: Remove vars that are set but not used.
23045 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23046 All callers changed.
23047 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23048 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23049 (decode_coding_charset): Remove vars that are set but not used.
23051 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23052 that is set but not used.
23054 * print.c (print_object): Remove var that is set but not used.
23056 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23057 The gnulib version avoids calling malloc in the usual case,
23058 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23059 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23060 * filelock.c (current_lock_owner): Likewise.
23061 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23062 * sysdep.c: Include allocator.h, careadlinkat.h.
23063 (emacs_no_realloc_allocator): New static constant.
23064 (emacs_readlink): New function.
23065 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23066 ../lib/careadlinkat.h.
23068 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23070 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23071 first non-nil return value).

23092 do not dereference NULL upon failed strdup
23093 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23094 (ns_get_family): Likewise.
23096 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23098 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23100 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23102 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23105 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23107 Add lexical binding.
23109 * window.c (Ftemp_output_buffer_show): New fun.
23110 (Fsave_window_excursion):

23116 Bind Qinternal_interpreter_environment.
23117 (Feval_buffer): Bind Qlexical_binding.
23118 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23120 (syms_of_lread): Declare `lexical-binding'.
23122 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23124 * keyboard.c (eval_dyn): New fun.
23125 (menu_item_eval_property): Use it.
23127 * image.c (parse_image_spec): Use Ffunctionp.
23129 * fns.c (concat, mapcar1): Accept byte-code-functions.
23131 * eval.c (Fsetq): Handle lexical vars.
23132 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23133 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23134 (FletX, Flet): Obey lexical binding.
23135 (Fcommandp): Handle closures.
23136 (Feval): New `lexical' arg.
23137 (eval_sub): New function extracted from Feval. Use it almost
23138 everywhere where Feval was used. Look up vars in lexical env.
23140 (Ffunctionp): Move from subr.el.
23141 (Ffuncall): Handle closures.
23142 (apply_lambda): Remove `eval_flags'.
23143 (funcall_lambda): Handle closures and new byte-code-functions.
23144 (Fspecial_variable_p): New function.
23145 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23146 but without exporting it to Lisp.
23148 * doc.c (Fdocumentation, store_function_docstring):
23149 * data.c (Finteractive_form): Handle closures.
23151 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23154 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23156 (exec_byte_code): New function extracted from Fbyte_code to handle new
23157 calling convention for byte-code-functions. Add new byte-codes.
23159 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23161 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23163 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23165 * xdisp.c (redisplay_internal): Fix prototype.
23167 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23169 * xdisp.c (SCROLL_LIMIT): New macro.
23170 (try_scrolling): Use it when setting scroll_limit.
23171 Limit scrolling to 100 screen lines.
23172 (redisplay_window): Even when falling back on "recentering",
23173 position point in the window according to scroll-conservatively,
23174 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23176 (try_scrolling): When point is above the window, allow searching
23177 as far as scroll_max, or one screenful, to compute vertical
23178 distance from PT to the scroll margin position. This prevents
23179 try_scrolling from unnecessarily failing when
23180 scroll-conservatively is set to a value slightly larger than the
23181 window height. Clean up the case of PT below the margin at bottom
23182 of window: scroll_max can no longer be INT_MAX. When aggressive
23183 scrolling is in use, don't let point enter the opposite scroll
23184 margin as result of the scroll.
23185 (syms_of_xdisp) <scroll-conservatively>: Document the
23186 threshold of 100 lines for never-recentering scrolling.
23188 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23190 * dispextern.h (move_it_by_lines):

23193 (message_log_check_duplicate): Remove parameters `prev_bol' and
23194 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23195 (redisplay_internal): Remove parameter `preserve_echo_area',
23196 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23198 * indent.c (Fvertical_motion):
23199 * window.c (window_scroll_pixel_based, Frecenter):
23200 Don't pass `need_y_p' to `move_it_by_lines'.
23202 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23204 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23205 steal a few bits to be more compact.
23206 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23207 Remove unneeded casts.
23209 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23211 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23213 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23214 binding" message (bug#7967).
23216 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23218 Fix more problems found by GCC 4.6.0's static checks.
23220 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23221 Remove unused local var.
23223 * editfns.c (Fmessage_box): Remove unused local var.
23225 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23226 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23227 Omit unused local vars.
23228 * window.c (shrink_windows): Omit unused local var.
23229 * menu.c (digest_single_submenu): Omit unused local var.
23230 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23231 Omit unused local var.
23233 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23234 Don't assume string length fits in int.
23235 (keyremap_step, read_key_sequence): Use size_t for sizes.
23236 (read_key_sequence): Don't check last_real_key_start redundantly.
23238 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23239 instead of alloca (Bug#8344).
23241 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23242 (Fbacktrace_frame): Don't assume nframes fits in int.
23244 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

23251 * cm.c (calccost): Turn while-do into do-while, for clarity.
23253 * keyboard.c (syms_of_keyboard): Use the same style as later
23254 in this function when indexing through an array. This also
23255 works around GCC bug 48267.
23257 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23259 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23261 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23262 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23264 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23265 This avoids undefined behavior on integer overflow, and is a bit
23266 more convenient anyway since it is compared to a size_t variable.
23268 Variadic C functions now count arguments with size_t, not int.
23269 This avoids an unnecessary limitation on 64-bit machines, which
23270 caused (substring ...) to crash on large vectors (Bug#8344).

23280 * fns.c (concat): Likewise.
23281 * frame.c (x_set_frame_parameters): Likewise.
23282 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23283 0 if not found, not -1. All callers changed.
23285 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23286 (stack_copy_size): Now size_t, not int.
23287 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23289 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

23308 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23309 don't set the hook to nil, but remove the offending function instead.
23310 (Qcommand_hook_internal): Remove, unused.
23311 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23312 Vcommand_hook_internal.
23314 * eval.c (enum run_hooks_condition): Remove.
23315 (funcall_nil, funcall_not): New functions.
23316 (run_hook_with_args): Call each function through a `funcall' argument.

23330 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

23491 * callint.c (Fcall_interactively):
23492 * buffer.c (Fkill_all_local_variables):
23493 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23495 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23496 unconditionally since it does the check itself.
23498 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23500 Fix more problems found by GCC 4.5.2's static checks.
23502 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23503 the first time through the loop, since we know p0 < p1 then.
23504 This also avoids a gcc -Wstrict-overflow warning.
23506 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23507 leading to a memory leak, possible in functions like
23508 load_charset_map_from_file that can allocate an unbounded number
23509 of objects (Bug#8318).
23511 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23512 that could (at least in theory) be that large.
23514 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23515 This is less likely to overflow, and avoids undefined behavior if
23516 overflow does occur. All callers changed. Use strtoul to scan
23517 for the unsigned long integer.
23518 (pint2hrstr): Simplify and tune code slightly.
23519 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23521 * scroll.c (do_scrolling): Work around GCC bug 48228.
23522 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
23524 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
23525 This also avoids a warning with gcc -Wstrict-overflow.
23526 (validate_x_resource_name): Simplify count usage.
23527 This also avoids a warning with gcc -Wstrict-overflow.
23529 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23532 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23534 * process.c (Fmake_network_process): Use socklen_t, not int,
23535 where POSIX says socklen_t is required in portable programs.
23536 This fixes a porting bug on hosts like 64-bit HP-UX, where
23537 socklen_t is wider than int (Bug#8277).
23538 (Fmake_network_process, server_accept_connection):
23539 (wait_reading_process_output, read_process_output):
23542 * process.c: Rename or move locals to avoid shadowing.

23552 Make tparam.h and terminfo.c consistent.
23553 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23554 Include tparam.h instead, since it declares them.
23555 * cm.h (PC): Remove extern decl; tparam.h now does this.
23556 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23557 * terminfo.c: Include tparam.h, to check interfaces.
23558 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23559 (tparam): Adjust signature to match interface in tparam.h;
23560 this removes some undefined behavior. Check that outstring and len
23561 are zero, which they always are with Emacs.
23562 * tparam.h (PC, BC, UP): New extern decls.
23564 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23565 (xftfont_open): Rename locals to avoid shadowing.
23567 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

23579 * composite.c (composition_compute_stop_pos): Rename local to
23581 (composition_reseat_it): Remove unused locals.
23582 (find_automatic_composition, composition_adjust_point): Likewise.
23583 (composition_update_it): Mark var as initialized.
23584 (find_automatic_composition): Mark vars as initialized,
23585 with a FIXME (Bug#8290).

23589 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23590 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23591 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23592 to avoid shadowing.
23594 * textprop.c (property_change_between_p): Remove; unused.
23596 * intervals.c (interval_start_pos): Now static.
23598 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23601 Rename locals to avoid shadowing.
23603 * sound.c (wav_play, au_play, Fplay_sound_internal):
23604 Fix pointer signedness.
23605 (alsa_choose_format): Remove unused local var.
23606 (wav_play): Initialize a variable to 0, to prevent undefined
23607 behavior (Bug#8278).
23609 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23611 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23613 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23614 clobbering (Bug#8298).
23615 * sysdep.c (sys_subshell): Likewise.
23616 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23618 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23619 This should get cleaned up, so that child_setup has the
23620 same signature on all platforms.
23622 * callproc.c (call_process_cleanup): Now static.
23623 (relocate_fd): Rename locals to avoid shadowing.
23625 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23627 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23628 not to be necessary, and produces flickering.
23630 2011-03-20 Glenn Morris <rgm@gnu.org>
23632 * config.in: Remove file.
23634 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23636 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23637 are now in src/globals.h.
23638 (syms_of_minibuf): Remove spurious & from previous change.
23640 2011-03-20 Leo Liu <sdl.web@gmail.com>
23642 * minibuf.c (completing-read-function): New variable.
23643 (completing-read-default): Rename from completing-read.
23644 (completing-read): Call completing-read-function.
23646 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23648 * xfaces.c (Fx_load_color_file):
23649 Read color file from absolute filename (bug#8250).
23651 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23653 * makefile.w32-in: Update dependencies.
23655 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23657 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23664 (sigchld_handler): Now static.
23666 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23667 That way, the code declares only the vars that it needs.
23668 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
23669 * s/cygwin.h (PTY_ITERATION): Likewise.

23677 (CONSTANTLIM): Remove; unused.
23678 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23679 Define only if needed.
23681 * unexelf.c (unexec): Name an expression,
23682 to avoid gcc -Wbad-function-cast warning.
23683 Use a different way to cause a compilation error if anyone uses
23684 n rather than nn, a way that does not involve shadowing.
23685 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23687 * deps.mk (unexalpha.o): Remove; unused.
23689 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23690 * unexec.h: New file.
23691 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23692 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23693 Depend on unexec.h.
23694 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23695 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23696 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23697 Change as necessary to match prototype in unexec.h.
23699 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

23744 * callint.c (quotify_arg, quotify_args): Now static.
23745 (Fcall_interactively): Rename locals to avoid shadowing.
23746 Use const pointer when appropriate.

23752 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23753 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23754 some of which prompt warnings from gcc -Wbad-function-cast.
23755 (Fformat_time_string, Fencode_time, Finsert_char):
23756 (Ftranslate_region_internal, Fformat):
23757 Rename or remove local vars to avoid shadowing.

23760 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23763 * lisp.h (eassert): Check that the argument compiles, even if
23764 ENABLE_CHECKING is not defined.
23766 * data.c (Findirect_variable): Name an expression, to avoid
23767 gcc -Wbad-function-cast warning.

23779 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23780 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23782 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23783 (GC_STRING_CHARS): Remove; not used.
23784 (Fmemory_limit): Cast sbrk's returned value to char *.
23786 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23787 avoids undefined behavior in theory.
23789 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23791 Use functions, not macros, for up- and down-casing (Bug#8254).
23792 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23793 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23794 to use the following functions instead of these macros.
23795 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23796 EMACS_INT, since callers assume the returned value fits in int.
23797 (upcase1): Likewise, for UPCASE_TABLE.
23798 (uppercasep, lowercasep, upcase): New static inline functions.
23799 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23808 which gcc can warn about.
23809 (regex_compile, re_match_2_internal): Mark locals as initialized.
23810 (RETALLOC_IF): Define only if needed.
23811 (WORDCHAR_P): Likewise. This one is never needed, but is used
23812 only in a comment talking about a compiler bug, so put inside
23813 the #if 0 of that comment.
23814 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23815 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23818 * search.c (boyer_moore): Rename locals to avoid shadowing.
23819 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

23841 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23842 New macros, so that the caller can use some names other than
23843 gcpro1, gcpro2, etc.
23844 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23846 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23847 argument, for consistency with GCPRO2_VAR, etc: it is now the
23848 prefix of the variable, not the variable itself. All uses
23850 * dired.c (directory_files_internal, file_name_completion):
23851 Rename locals to avoid shadowing.
23853 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23854 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23855 dired.c's scmp function, had undefined behavior.
23856 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23857 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23858 * buffer.h: ... to here, because these macros use current_buffer,
23859 and the new implementation with inline functions needs to have
23860 current_buffer in scope now, rather than later when the macros
23862 (downcase, upcase1): New static inline functions.
23863 (DOWNCASE, UPCASE1): Reimplement using these functions.
23864 This avoids undefined behavior in expressions like
23865 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23866 from race conditions in accessing the global variables
23867 case_temp1 and case_temp2.
23868 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23869 * lisp.h (case_temp1, case_temp2): Remove their decls.
23870 * character.h (ASCII_CHAR_P): Move from here ...
23871 * lisp.h: ... to here, so that the inline functions mentioned
23872 above can use them.
23874 * dired.c (directory_files_internal_unwind): Now static.
23876 * fileio.c (file_name_as_directory, directory_file_name):
23877 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23879 (file_name_as_directory): Use const pointers when appropriate.
23880 (Fexpand_file_name): Likewise. In particular, newdir might
23881 point at constant storage, so make it a const pointer.
23882 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23883 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23885 (Fset_file_times, Finsert_file_contents, auto_save_error):
23886 Rename locals to avoid shadowing.
23888 * minibuf.c (choose_minibuf_frame_1): Now static.

23890 to avoid shadowing.
23892 * marker.c (bytepos_to_charpos): Remove; unused.
23894 * lisp.h (verify_bytepos, count_markers): New decls,
23895 so that gcc does not warn that these functions aren't declared.
23897 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23898 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23899 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23900 (copy_text): Remove unused local var.
23902 * filelock.c (within_one_second): Now static.
23903 (lock_file_1): Rename local to avoid shadowing.
23905 * buffer.c (fix_overlays_before): Mark locals as initialized.
23906 (fix_start_end_in_overlays): Likewise. This function should be
23907 simplified by using pointers-to-pointers, but that's a different
23909 (switch_to_buffer_1): Now static.
23910 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23911 (report_overlay_modification): Rename locals to avoid shadowing.
23913 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23914 Fix pointer signedness issue.
23915 (sys_subshell): Mark local as volatile if checking for lint,
23916 to suppress a gcc -Wclobbered warning that does not seem to be right.
23917 (MAXPATHLEN): Define only if needed.
23919 * process.c (serial_open, serial_configure): Move decls from here ...
23920 * systty.h: ... to here, so that they can be checked.
23922 * fns.c (get_random, seed_random): Move extern decls from here ...
23923 * lisp.h: ... to here, so that they can be checked.
23925 * sysdep.c (reset_io): Now static.
23926 (wait_for_termination_signal): Remove; unused.
23928 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23931 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23932 (DENSE_TABLE_SIZE): Remove; unused.
23933 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23934 (describe_map_tree):
23935 Rename locals to avoid shadowing.
23937 * keyboard.c: Declare functions static if they are not used elsewhere.
