505 * unexelf.c: Don't assume ElfW (Half) fits in int.
506 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
507 when dealing with ElfW (Half) values, since they can exceed 2**31
508 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
509 (entry_address): Omit unused NUM arg. All uses changed.
511 2013-05-07 Juri Linkov <juri@jurta.org>

567 and dpyinfo->Xatom_net_current_desktop.
569 2013-05-06 Eli Zaretskii <eliz@gnu.org>
571 * xdisp.c (pos_visible_p): Use the special code for finding the
572 beginning of a display property or overlay for any "replacing"
573 display property, not just for display strings. This solves
574 incorrect reporting of position by posn-at-point. (Bug#14241)
576 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
578 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
579 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
580 Verify that ElfW (Half) fits in int.
581 (fatal): Use same signature as lisp.h.
582 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
583 configure and build with -DUNEXELF_DEBUG without worrying about
584 other modules that use DEBUG.
585 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
586 possibly-wide integers now uses it instead of plain fprintf.
587 (entry_address): New function, which avoids problems with 32-bit
588 overflow on 64-bit hosts.
589 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
590 (round_up): Don't assume the remainder fits in int.
591 (find_section): Use bool for boolean. Simplify debug code.
592 (unexec): Don't assume file sizes fit in int or size_t.
593 Omit unnecessary trailing newline in 'fatal' format.
594 Use strerror rather than outputting decimal error number.
595 Remove unused code when emacs is not defined;
596 this file relies on Emacs now.

599 * regex.c: Fix problems when DEBUG is defined.
600 (extract_number, extract_number_and_incr): Define regardless of
601 whether DEBUG is defined; that's simpler and makes the code less
602 likely to go stale in the normal case when DEBUG is not defined.
603 Return int rather than taking an int * arg. All callers changed.
604 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
605 Remove, replacing with ...
606 (DEBUG_PRINT): New macro. All callers changed.
607 (DEBUG_COMPILES_ARGUMENTS): New macro.

610 Use prototype rather than old-style definition.
611 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
612 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
613 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
614 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
615 Don't assume ptrdiff_t, size_t, and long are the same width as int.
616 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
617 This matters only when DEBUG is defined.
619 2013-05-05 Eli Zaretskii <eliz@gnu.org>
621 * xdisp.c (set_iterator_to_next): Set the
622 ignore_overlay_strings_at_pos_p flag only if we are _really_
623 iterating over an overlay string, as indicated by the
624 current.overlay_string_index member. (Bug#14306)
626 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
628 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
629 to where it is used, to avoid autorelease issues (Bug#14050).
631 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
633 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
634 * fileio.c (syms_of_fileio): Implement this.
635 * filelock.c (create_lock_file): If symbolic links don't work, so
636 we use a regular file as a lock file, do not fsync the lock file;
639 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>

650 Use parentheses to disambiguate last part of the condition.
652 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
653 assertion violations. (Bug#14062)
655 2013-05-01 David Reitter <david.reitter@gmail.com>
657 * nsfns.m (ns_tooltip): Initialize.
659 2013-04-28 Eli Zaretskii <eliz@gnu.org>
661 * coding.c (decode_coding_gap): Don't remove the character before
662 a newline unless it's a CR character. (Bug#14287)
664 2013-04-28 Dan Nicolaescu <dann@gnu.org>
666 * dispextern.h (struct face): Move enum face_underline_type

676 2013-04-27 Juri Linkov <juri@jurta.org>
678 * callint.c (Fcall_interactively): Call `Qread_number' for
679 interactive code letter `n' instead of using duplicate code.
682 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
684 * systime.h (make_timeval): Declare as 'const'.
686 2013-04-27 Kenichi Handa <handa@gnu.org>
688 * font.c (font_open_entity): Always open a font of manageable
691 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
693 Port better to AIX (Bug#14258).
694 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,

705 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
706 Without this fix, "make distclean" leaves stamp-h1 behind.

710 * w32fns.c (w32_fullscreen_rect): New function to compute the
711 window rectangle for the given fullscreen mode.
712 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
713 longer tunes the window size. This keeps the window's edges flush
714 with the screen and allows the taskbar to hide itself in fullboth.
716 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
717 window decorations and uses the entire screen.
719 * w32term.h (w32_fullscreen_rect) Add prototype.

740 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
741 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
742 parentheses where appropriate.
744 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
746 * keyboard.c (timer_start_idle): Remove no-longer-used local.
748 2013-04-14 Eli Zaretskii <eliz@gnu.org>
750 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
751 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
752 Mention in the doc string that setting these variables takes
753 effect only after a call to set-window-buffer. (Bug#14200)
755 2013-04-13 Eli Zaretskii <eliz@gnu.org>
757 * indent.c (Fvertical_motion): Don't consider display strings on
758 overlay strings as display strings on the buffer position we
759 started from. This prevents vertical cursor motion from jumping
760 more than one line when there's an overlay string with a display
761 property at end of line.
762 Reported by Karl Chen <Karl.Chen@quarl.org> in
763 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

768 already selected (bug#14191).
770 2013-04-11 Eli Zaretskii <eliz@gnu.org>
772 * window.c (Fwindow_end): Test more flags, including the buffer's
773 last_overlay_modified flag, to determine whether the window's
774 display is really up-to-date. Prevents the function from
775 returning a stale value. (Bug#14170)
776 (Fwindow_line_height): Fix the test for up-to-date-ness of the
779 2013-04-10 Eli Zaretskii <eliz@gnu.org>
781 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
782 garbaged only if it is not already the top frame on its TTY.
783 This prevents flickering due to constant redrawing of TTY frames when
784 there are GUI frames open in the same session. (Bug#13864)
786 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
788 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
789 of marking the idle timers directly.
791 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
793 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
796 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

815 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
818 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
820 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
821 This bug was introduced by my 2013-02-25 change that simplified
822 data_start configuration. Without this change, on GNU/Linux
823 an Emacs configured with --enable-profiling fails immediately
824 due to a profiler signal.
825 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
826 with these flags. On platforms where special flags are needed
827 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
828 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
829 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
831 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

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

990 2013-03-28 Dmitry Antipov <dmantipov@yandex.ru>
992 * window.h (struct window): Replace hchild, vchild and buffer slots
993 with the only contents slot. This is possible because each valid
994 window may have either the child window (in vertical or horizontal
995 combination) or buffer to display (for the leaf window). Using that,
996 a lof of operations to traverse and/or change window hierarchies may
997 be simplified. New member horizontal is used to distinguish between
998 horizontal and vertical combinations of internal windows.
999 (WINDOW_LEAF_P, WINDOW_HORIZONTAL_COMBINATION_P)

1025 (frame_row_to_window, mirror_line_dance, check_window_matrix_pointers)
1026 (update_window_tree, set_window_update_flags): Simplify the loop.
1027 (sync_window_with_frame_matrix_rows): Enforce live window.
1028 Use contents slot, not buffer, where appropriate.

1030 and WINDOW_HORIZONTAL_COMBINATION_P.
1031 (make_frame_visible_1): Simplify the loop.
1032 Use contents slot, not buffer, where appropriate.
1033 * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
1034 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1035 (expose_window_tree): Likewise.
1036 Use contents slot, not buffer, where appropriate.
1037 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1038 to avoid deleted windows. Use contents slot instead of buffer.
1039 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:

1206 2013-03-23 Eli Zaretskii <eliz@gnu.org>
1208 * w32term.c (w32fullscreen_hook): Use FRAME_NORMAL_WIDTH,
1209 FRAME_NORMAL_HEIGHT, and FRAME_PREV_FSMODE, instead of static
1210 variables, to save and restore frame dimensions.
1211 Use FRAME_NORMAL_LEFT and FRAME_NORMAL_TOP to restore frame position
1212 after returning from a 'fullscreen' configuration.

1299 New functions to provide defaults when no window system available.
1300 (FRAME_RES_X, FRAME_RES_Y): New macros.

1359 Use getFilename and getDirectory.
1360 (getFilename, getDirectory): New methods for EmacsSavePanel and
1362 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

1376 * coding.c (detect_ascii): New function.
1377 (detect_coding): Set coding->head_ascii and coding->eol_seen only
1378 when the source bytes are actually scanned. On detecting for
1379 coding_category_utf_8_auto, call detect_ascii instead of scanning
1380 source bytes directly.
1381 (produce_chars): Call insert_from_gap with the new arg 0.
1382 (encode_coding): Likewise.
1383 (decode_coding_gap): Control ASCII optimization by the variable

1411 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1414 2013-03-13 Daniel Colascione <dancol@dancol.org>
1416 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1417 too so that these builds can use Cygwin's file conversion
1418 functions. (We've been building and linking cygw32.o all along
1419 and just not using it.)
1421 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1423 File synchronization fixes (Bug#13944).

1429 available if the system lacks one.
1430 (Fwrite_regin): Retry fsync if interrupted.
1432 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1434 * w32term.c (w32_read_socket): If the Emacs frame is being
1435 activated, call w32fullscreen_hook, to make sure the new frame
1436 dimensions are in effect. (Bug#13937)
1438 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1440 * xdisp.c (init_iterator): Simplify because both character and byte
1441 positions are either specified or -1. Add eassert. Adjust comment.
1442 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1443 character and byte positions can be obtained from marker.

1460 a function pointer type; the C Standard requires this.
1462 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1463 Include <sys/param.h> unconditionally, as that works elsewhere and
1464 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1465 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

1499 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1500 can just use du like other systems.
1502 * coding.c (from_unicode_buffer): Declare.

1551 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1552 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1553 from Elisp via unread-command-events.
1555 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1556 functions to mean "no change".
1558 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1560 region-cache.c, scroll.c, search.c: Use bool for booleans.

1566 (search_regs_saved, Fregexp_quote):
1567 Use bool for boolean.
1568 * region-cache.c (region_cache_forward, region_cache_backward):
1569 Fix comments to match code: these functions return int, not boolean.
1571 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1573 * search.c (find_newline): Accept start and end byte positions
1574 as arguments and allow -1 if not known.

1576 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1577 * bidi.c (bidi_find_paragraph_start): Pass byte position to

1580 Adjust call to find_newline.
1581 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1606 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1608 * bidi.c (bidi_fetch_char): Swap first and second arguments
1609 to match other functions accepting character and byte positions.
1611 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1612 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1613 when you need just to move to the previous buffer position.
1614 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1616 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1635 (Frecenter): Adjust calls to vmotion.
1637 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1639 * lisp.h (list2i, list3i): New functions.

1689 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1691 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1692 * sysdep.c (list_system_processes)
1693 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1694 Make it a stub in this case; otherwise the build might fail,
1695 and this code hasn't been tested on such hosts anyway.
1696 Problem reported by Nelson H. F. Beebe in
1697 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1698 and analyzed by Jérémie Courrèges-Anglas in
1699 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1701 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1703 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1704 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1705 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1706 * bidi.c (bidi_find_paragraph_start): Likewise.
1707 * indent.c (vmotion): Likewise.
1709 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1711 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1712 * filelock.c: Include <c-ctype.h>.
1713 (MAX_LFINFO): New top-level constant.
1714 (lock_info_type): Remove members pid, boot_time. Add members at,
1715 dot, colon. Change user member to be the entire buffer, not a
1716 pointer. This allows us to handle the case where a foreign
1717 pid or boot time exceeds the local range. All uses changed.
1718 (LINKS_MIGHT_NOT_WORK): New constant.
1719 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1720 (defined_WINDOWSNT): Remove.
1721 (MAKE_LOCK_NAME, file_in_lock_file_name):
1722 Always use .#FILE (not .#-FILE) for the file lock,
1723 even if it is a regular file.
1724 (rename_lock_file): New function.
1725 (create_lock_file): Use it.
1726 (create_lock_file, read_lock_data):
1727 Prefer a symbolic link for the lock file, falling back on a
1728 regular file if symlinks don't work. Do not try to create
1729 symlinks on MS-Windows, due to security hassles. Stick with
1730 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1731 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1732 host may be using a Windowsish file system, and cannot use
1733 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1734 doesn't work. Don't fail merely because of a symlink-contents
1735 length limit in the current file system; fall back on regular
1736 files. Increase the symlink contents length limit to 8 KiB, this
1737 should be big enough for any real use and doesn't crunch the
1739 (create_lock_file, lock_file_1, read_lock_data):
1740 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1741 (lock_file_1): Return error number, not bool. All callers changed.
1742 (ELOOP): New macro, if not already defined.
1743 (read_lock_data): Return size of lock file contents, not Lisp object.
1744 All callers changed. Handle a race condition if some other process
1745 replaces a regular-file lock with a symlink lock or vice versa,
1746 while we're trying to read the lock.
1747 (current_lock_owner): Parse contents more carefully, to help avoid
1748 confusing a regular-file lock with some other application's use
1749 of the file. Check for lock file contents being too long, or
1750 not parsing correctly.
1751 (current_lock_owner, lock_file):
1752 Allow foreign pid and boot times that exceed the local range.
1753 (current_lock_owner, lock_if_free, lock_file):
1754 Simplify allocation of lock file contents.
1755 * w32.c (sys_rename_replace): New function, containing most of
1756 the contents of the old sys_rename.
1757 (sys_rename): Use it.
1758 (fchmod): New dummy function.
1759 * w32.h (sys_rename_replace, fchmod): New decls.
1761 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1763 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1764 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1765 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1766 <dmantipov@yandex.ru>.
1768 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1770 * composite.c (get_composition_id, fill_gstring_header):
1771 Use make_uninit_vector where appropriate.
1772 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1773 * xselect.c (clean_local_selection_data): Likewise.
1775 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1777 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1778 * image.c (imagemagick_load_image): Calculate height and width
1779 after flattening the image, not before.
1781 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1783 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1784 * ftfont.c (ftfont_shape_by_flt): Likewise.
1785 * w32uniscribe.c (uniscribe_shape): Likewise.
1787 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1789 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1790 The old approach, which fell back on DIR/.#FILE.0 through
1791 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1792 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1793 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1794 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1795 because the locking mechanism was never reliable in that case).
1796 This patch fixes this and other bugs discovered by a code
1797 inspection that was prompted by
1798 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1799 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1800 to avoid interoperability problems between the MS-Windows and
1801 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1802 instances of Emacs now ignore each others' locks.
1803 * filelock.c (defined_WINDOWSNT): New constant.
1804 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1805 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1806 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1807 regular files on MS-Windows hosts.
1808 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1809 Use SAFE_ALLOCA to avoid problems with long file names.
1810 (MAX_LFINFO): Now a local constant, not a global macro.
1811 (IS_LOCK_FILE): Remove.
1812 (lock_file_1): Don't inspect errno if symlink call succeeds;
1813 that's not portable.
1814 (lock_file): Document that this function can return if lock
1816 (lock_file): Don't access freed storage.
1818 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1820 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1822 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1824 * textprop.c: Use bool for booleans.
1825 (validate_interval_range, Fadd_text_properties)
1826 (Fremove_text_properties): Prefer bool to int when either works.
1828 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1830 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1831 If the interval tree changes as a side effect of calling
1832 modify_region, re-do processing starting from the call to
1833 validate_interval_range. (Bug#13743)
1835 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1837 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1840 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1842 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1843 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1844 access to the lock file until it is written and closed.
1847 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1849 * callint.c (Qcall_interactively):
1850 * macros.c (Qexecute_kbd_macro):
1853 2013-02-26 Bastien Guerry <bzg@gnu.org>
1855 * window.c (Frecenter): Tiny docstring enhancement.
1857 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1859 Minor textprop integer cleanup.
1860 * intervals.h, textprop.c (add_text_properties_from_list):
1861 Return void, not int, since nobody uses the return value.
1862 * textprop.c (validate_plist, add_properties, remove_properties)
1863 (Fadd_text_properties):
1864 Don't assume list length fits in int.
1865 (interval_has_all_properties, interval_has_some_properties)
1866 (interval_has_some_properties_list, add_properties, remove_properties)

1868 (Fremove_list_of_text_properties, text_property_stickiness):
1869 Use bool for booleans.
1870 (Fadd_text_properties, Fremove_text_properties):
1871 (Fremove_list_of_text_properties):
1872 Reindent do-while as per GNU style.
1874 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1876 Implement CLASH_DETECTION for MS-Windows.
1878 * filelock.c [WINDOWSNT]: Include w32.h.
1879 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1880 function of that name. Up-case the macro arguments.
1881 (IS_LOCK_FILE): New macro.
1882 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1883 (create_lock_file): New function, with body extracted from

1886 the lock information as its contents.
1887 (read_lock_data): New function, on Posix platforms just calls
1889 [WINDOWSNT]: Read the lock info from the file.
1890 (current_lock_owner): Call read_lock_data instead of calling
1891 emacs_readlinkat directly.
1892 (lock_file) [WINDOWSNT]: Run the file name through
1895 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1896 just check if the process by that PID exists.
1898 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1899 also present, as doing so will fail to error out if the file
1902 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1904 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1905 (Fremove_list_of_text_properties): Skip all of the intervals in
1906 the region between START and END that already have resp. don't
1907 have the requested properties, not just the first one.
1908 Add assertions that the loop afterwards always modifies the
1909 properties. (Bug#13743)
1911 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1913 * callint.c (Fcall_interactively): Use the right lexical environment

1927 (temacs$(EXEEXT)): Use $(ALLOBJS).
1928 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1929 * deps.mk (vm-limit.o):
1930 * makefile.w32-in ($(BLD)/vm-limit.$(O)):

1939 * vm-limit.c: Move most of mem-limits.h's contents here.
1940 (data_start): New decl. It's OK if this is approximate,
1941 so simplify-away some unnecessary exactness.
1942 (POINTER): Remove; all uses removed.
1943 (data_space_start): Now char *, to avoid casts.
1944 (exceeds_lisp_ptr): New function, replacing the old

1964 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1966 Assume C89 or better.
1967 * ralloc.c (SIZE, POINTER, NIL):
1968 * vm-limit.c (POINTER):
1969 Remove, replacing all uses with C89 equivalents. These old
1970 symbols were present only for porting to pre-C89 platforms.
1972 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1974 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1975 This avoids warning messages reported as part of Bug#13546.

1990 2013-02-19 Daniel Colascione <dancol@dancol.org>
1992 * sheap.c (report_sheap_usage): Use message, not message1, so
1993 that we don't try to create a buffer while we're in the middle
1994 of dumping Emacs. Explain why.
1996 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1998 * search.c (find_newline): Return byte position in bytepos.

2011 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2013 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2014 resources were not orderly released.
2016 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2018 * xdisp.c (x_draw_vertical_border): For a window that is neither

2045 unconditionally. (Bug#9066)
2047 * w32.c (set_errno): Reset h_errno and don't set it to any other
2048 value. Set errno instead.

2061 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2063 * keyboard.c (read_char): Fix calculation of auto-save time out
2064 when auto-save-timeout is less than 4. (Bug#13720)
2066 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
2067 time. Improve diagnostics in DebPrint. (Bug#13546)

2075 value that is out of bounds.
2076 (sys_accept): If fd is negative, do not set up the child_process

2089 (decode_mode_spec_coding, message3):
2090 * xfaces.c (face_at_string_position): Use bool for booleans.
2093 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2095 Fix AIX port (Bug#13650).
2096 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2097 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2098 was #undeffed earlier, so it cannot be used as a macro here.
2099 Use the constant and not the macro.
2101 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2103 * w32proc.c (new_child): If no vacant slots are found in
2104 child_procs[], make another pass looking for slots whose process
2105 has exited or died. (Bug#13546)
2107 * w32.c (sys_pipe): When failing due to file descriptors above
2108 MAXDESC, set errno to EMFILE.
2109 (_sys_read_ahead): Update cp->status when failing to read serial
2110 communications input, so that the status doesn't stay at
2111 STATUS_READ_IN_PROGRESS. (Bug#13546)
2113 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2115 * gtkutil.c (tb_size_cb): New function.
2116 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2118 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2120 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2123 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2125 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2127 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

2137 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2139 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2141 Improve AIX port some more (Bug#13650).
2142 With this, it should be as good as it was in 23.3, though it's
2143 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2144 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2145 * unexaix.c (start_of_text): Remove.
2146 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2147 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2148 (orig_load_scnptr, orig_data_scnptr):
2149 Now off_t, not long, since they are file offsets.
2150 (make_hdr): Use _data, not start_of_data ().
2151 This is the key part of the fix.
2152 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2153 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2155 * pre-crt0.c (data_start): Initialize to 1.
2156 This ports to compilers that optimize the external declaration
2157 'int x = 0;' as if it were 'int x;' to shrink the executable.
2159 Improve AIX port (Bug#13650).
2160 This doesn't fix the bug, but it makes progress: Emacs builds now.
2161 * unexaix.c: Include inttypes.h, stdarg.h.
2162 (report_error, report_error_1): Mark as _Noreturn.
2163 (report_error): Don't report the wrong errno.
2164 (report_error_1): Now varargs. All callers changed.
2165 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2166 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2167 (write_ptr): Use %p to print address rather than %lx and a cast
2168 to unsigned long. Grow buffer a bit, to be safer.
2170 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2172 * bidi.c (bidi_resolve_neutral): After finding the next
2173 non-neutral character, accept NEUTRAL_ON type as well, because
2174 directional control characters, such as LRE and RLE, have their
2175 type converted to that by bidi_resolve_weak. This avoids aborts
2176 when LRE/RLE follows a run of neutrals.
2177 (bidi_move_to_visually_next): Assert that return value of
2178 bidi_peek_at_next_level is non-negative. Negative values will
2181 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2183 Minor getenv-related fixes.
2184 * callproc.c (Fcall_process_region) [!DOS_NT]:

2186 * callproc.c (init_callproc):
2187 * dispnew.c (init_display):
2188 * sysdep.c (sys_subshell):
2189 Omit unnecessary cast of getenv or egetenv.

2193 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2194 Update dependencies.
2196 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2198 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2200 (display_line): Set w->region_showing to the value of
2201 it->region_beg_charpos, not to -1. This fixes redisplay
2202 optimization when cursor is moved up after M->. (Bug#13623)
2204 (try_scrolling): Scroll text up more if point is too close to ZV
2205 and inside the scroll margin. This makes sure point is moved
2206 outside the scroll margin in these cases.
2208 * window.h (struct window): region_showing can no longer be
2211 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2213 Tune by using memchr and memrchr.
2214 * doc.c (Fsnarf_documentation):
2215 * fileio.c (Fsubstitute_in_file_name):
2216 * search.c (find_newline, scan_newline):
2217 * xdisp.c (pos_visible_p, display_count_lines):
2218 Use memchr and memrchr rather than scanning byte-by-byte.
2219 * search.c (find_newline): Rename from scan_buffer.
2220 Omit first arg TARGET, as it's always '\n'. All callers changed.
2222 Clean up read_key_sequence a tiny bit more.
2223 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2224 (read_key_sequence): Remove unused locals.
2226 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2228 Clean up read_key_sequence a bit; reread active keymaps after first event.
2229 * keyboard.c (read_char, read_char_x_menu_prompt)
2230 (read_char_minibuf_menu_prompt):
2231 Replace nmaps+maps with a single `map' arg.
2232 (follow_key): Operate on a single map.
2233 (active_maps): New function.
2234 (test_undefined): Also return true for nil bindings.
2235 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2236 a single (composed) keymap. Remember `first_event' to choose the right
2237 set of active keymaps. Recompute the set of keymaps after receiving
2238 the first event. Remove GOBBLE_FIRST_EVENT.
2239 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2240 * keyboard.h (read_char): Update declaration.
2241 * lread.c (read_filtered_event): Adjust call to read_char.
2243 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2245 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2246 Don't use the limitation on backwards movement when lines are truncated
2247 in the window. (Bug#13675)
2249 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2251 * marker.c (set_marker_internal): If desired position is passed
2252 as a marker, avoid call to buf_charpos_to_bytepos.
2253 * window.c (Fset_window_point): Omit redundant type checking.
2254 (Fset_window_start): Likewise. Format comment.
2255 (window_scroll_pixel_based): Use set_marker_restricted_both
2256 with character and byte positions obtained from an iterator.
2257 (Fset_window_configuration): Use set_marker_restricted_both.
2258 * xdisp.c (message_dolog): Likewise.
2260 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2262 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2263 When text lines are longer than window's screen lines, don't move back
2264 too far. This speeds up some redisplay operations. (Bug#13675)
2266 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2268 * syntax.c (scan_sexps_forward): Fix byte position calculation
2269 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2271 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2273 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2274 that was not needed.
2276 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2278 Minor hashing refactoring.
2279 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2280 (sxhash_float): Return EMACS_UINT, for consistency with the other
2282 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2283 non-static inline function and therefore can't use static vars.
2284 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2285 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2286 with the other hash functions.
2288 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2290 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2291 XXXXXX part of the temporary file pattern is not downcased even
2292 when w32-downcase-file-names is non-nil. (Bug#13661)
2294 * xdisp.c (decode_mode_spec): Remove handling of %t.

2316 * lisp.h (make_uninit_vector): New function.
2317 * alloc.c (Fvector, Fmake_byte_code):

2336 argument is known to be a vector.
2337 * fns.c (Flocale_info): Likewise for ASET.
2338 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2339 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2341 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2343 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2346 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2347 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
2348 updateCollectionBehaviour.
2350 * nsterm.m (NEW_STYLE_FS): Remove.
2351 (ns_last_use_native_fullscreen): New variable.
2352 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2353 (x_set_window_size): Do not take title bar and tool bar into account
2354 if isFullscreen returns YES.
2355 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2356 (check_native_fs): New function.
2357 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2358 (ns_term_init): Remove NEW_STYLE_FS.
2359 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2360 and tool bar if isFullscreen returns NO.
2361 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2362 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2363 with HAVE_NATIVE_FS.
2364 (window:willUseFullScreenPresentationOptions:): New method.
2365 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
2366 Hide toolbar if not enabled (Bug#13444).

2368 Restore tool bar if enabled, hide it otherwise (Bug#13444).
2369 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
2370 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
2371 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
2372 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
2373 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2374 (syms_of_nsterm): Add ns-use-native-fullscreen.
2376 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2378 * fileio.c (Qchoose_write_coding_system): Now static.
2380 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2382 * xdisp.c (window_buffer_changed): region_showing can be negative,
2383 which still means region is being displayed.
2384 (redisplay_internal): Resurrect code that forced redisplay of the
2385 whole window when showing region and the mark has changed.
2386 Record the new mark position to allow redisplay optimizations.
2387 (display_line): If it->region_beg_charpos is non-zero, set the
2388 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2390 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2391 not bitfield of 1 bit.
2393 2013-02-03 Daniel Colascione <dancol@dancol.org>
2395 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2396 daemon mode works on cygw32 when Emacs is installed and not just
2399 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2401 Avoid file time stamp bug on MS-Windows (Bug#13149).
2402 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2403 as FAT32 doesn't update time stamps when truncating them.
2404 Also, check that a file time stamp is not a multiple of 100 ns;
2405 this should catch all instances of the problem on MS-Windows,
2406 as its native file system resolution is 100 ns or worse, and
2407 checking for a non-multiple of 100 ns should impose only a small
2408 overhead on systems with ns resolution.
2410 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2412 Avoid encoding file names on MS-Windows when they need to be run
2413 through dostounix_filename.
2414 * w32.c (normalize_filename): Accept an additional argument
2415 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2416 downcase it even if w32-downcase-file-names is non-nil.
2417 (dostounix_filename): Accept an additional argument MULTIBYTE and
2418 pass it to normalize_filename.
2419 (emacs_root_dir): Adjust.
2421 * msdos.h (dostounix_filename): Adjust prototype.
2423 * w32.h (dostounix_filename): Adjust prototype.
2425 * msdos.c (dostounix_filename): Accept an additional argument and
2427 (init_environment): Adjust callers of dostounix_filename.
2429 * fileio.c (Ffile_name_directory, file_name_as_directory)
2430 (directory_file_name, Fexpand_file_name)
2431 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2433 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2435 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2436 variables, as egetenv is case-insensitive for DOS_NT.
2438 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2439 with an encoded file name.
2441 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2442 Adjust calls to dostounix_filename.
2444 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2446 * unexw32.c (unexec): Adjust call to dostounix_filename.
2448 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2450 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2453 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2456 * callproc.c (Fcall_process): Make sure program name in PATH and
2457 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2458 is passed to exec/spawnve, which fails unless the file-name
2461 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2462 even if w32-quote-process-args is nil.
2464 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2466 Fix timestamp bug when write-region appends nothing (Bug#13149).
2467 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2468 the file's time stamp doesn't change if Emacs happens to write nothing
2469 to the file, and on a buggy file system this could cause Emacs to
2470 incorrectly infer that the file system doesn't have the bug.
2471 Avoid this problem by inhibiting the inference in this case.
2473 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2475 * window.h (struct window): Convert base_line_number, base_line_pos
2476 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2477 Convert region_showing member from Lisp_Object to bitfield.
2478 Remove sequence_number member. Adjust comments.
2479 * window.c (sequence_number): Remove.
2480 (make_window): Initialize column_number_displayed.
2481 * print.c (print_object): Follow the printed representation of
2482 frames and print window pointer to distinguish between windows.
2483 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2484 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2485 (wset_column_number_displayed, wset_region_showing): Remove.
2486 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2487 (try_scrolling, try_cursor_movement, redisplay_window)
2488 (try_window_reusing_current_matrix, try_window_id, display_line)
2489 (display_mode_lines, decode_mode_spec): Adjust users.
2490 * .gdbinit (pwinx): Do not print sequence_number.
2492 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2494 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2495 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2496 * dired.c: Include <fcntl.h>.
2497 (open_directory): New function, which uses open and fdopendir
2498 rather than opendir. DOS_NT platforms still use opendir, though.
2499 (directory_files_internal, file_name_completion): Use it.
2500 (file_attributes): New function, with most of the old Ffile_attributes.
2501 (directory_files_internal, Ffile_attributes): Use it.
2502 (file_attributes, file_name_completion_stat): First arg is now fd,
2503 not dir name. All uses changed. Use fstatat rather than lstat +
2505 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2506 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2507 (emacs_readlinkat): New function, with much of the old
2508 Ffile_symlink_p, but with an fd argument for speed.
2509 It uses readlinkat rather than careadlinkatcwd, so that it
2510 need not assume the working directory.
2511 (Ffile_symlink_p): Use it.
2512 * filelock.c (current_lock_owner): Use emacs_readlinkat
2513 rather than emacs_readlink.
2514 * lisp.h (emacs_readlinkat): New decl.
2515 (READLINK_BUFSIZE, emacs_readlink): Remove.
2516 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2517 (emacs_norealloc_allocator, emacs_readlink): Remove.
2518 This stuff is moved to fileio.c.
2519 * w32.c (fstatat, readlinkat): New functions.
2520 (careadlinkat): Don't check that fd == AT_FDCWD.
2521 (careadlinkatcwd): Remove; no longer needed.
2523 2013-01-31 Glenn Morris <rgm@gnu.org>
2525 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2526 (Fwrite_region): Update for new choose_write_coding_system args.
2527 Move the last piece of choose_write_coding_system here. (Bug#13522)
2528 (syms_of_fileio): Add choose-write-coding-system.
2530 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2532 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2533 (sys_close): Zero out the flags for the file descriptor before
2534 closing it. (Bug#13546)
2536 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2537 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2538 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2541 * w32.c (w32_get_long_filename, init_environment, readlink):
2542 Support file names encoded in DBCS codepages.
2543 (readlink): Use the current file-name-coding-system, not the ANSI
2544 codepage, to decode and handle targets of symlinks.
2546 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2548 * w32.c (opendir): Now accepts a 'const char *'.
2550 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2552 Remove obsolete redisplay code. See the discussion at
2553 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2554 * dispnew.c (preemption_period, preemption_next_check): Remove.
2555 (Vredisplay_preemption_period): Likewise.
2556 (update_frame, update_single_window, update_window, update_frame_1):
2557 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2558 used, following the 2012-06-22 change.
2560 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2562 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2564 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2566 * font.c (num_fonts): Remove the leftover from old
2567 debugging code. Adjust comment style here and there.
2568 * insdel.c (insert_1): Remove.
2569 * lisp.h (insert_1): Remove prototype.
2570 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2572 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2574 * w32.c (max_filename_mbslen): New function.
2575 (normalize_filename, readdir): Use it to detect locales where ANSI
2576 encoding of file names uses a double-byte character set (DBCS).
2577 If a DBCS encoding is used, advance by characters using
2578 CharNextExA, instead of incrementing a 'char *' pointer.
2579 Use _mbslwr instead of _strlwr. (Bug#13515)
2581 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2582 request of memory reservation to 1.7GB. (Bug#13065)
2584 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2586 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2587 at check_extra_latin label. (Bug#13505)
2589 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2591 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2592 Avoid redundant calls to strlen.
2594 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2596 Drop async_visible and async_iconified fields of struct frame.
2597 This is possible because async input is gone; for details, see
2598 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2599 * frame.h (struct frame): Remove async_visible and async_iconified
2600 members, convert garbaged to unsigned bitfield. Adjust comments.
2601 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2602 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2603 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2604 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2605 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2607 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2608 properly. Likewise for obscured.
2610 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2613 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2615 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2617 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2618 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2620 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2622 * xdisp.c (message2, message2_nolog): Remove functions.
2623 (message3, message3_nolog): Extract nbytes and multibyteness directly
2624 from the string. Change all callers.
2625 (message3_nolog): Don't set message_enable_multibyte since set_message
2626 will reset it anyway.
2627 (message1, message1_nolog): Use message3.
2628 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2629 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2630 (set_message): Drop all but the second arg, which has to be a string.
2631 (set_message_1): Simplify now that we know that a1 is NULL and the
2632 second arg is a string.
2633 * frame.h (struct frame): Remove `message_buf' field.
2634 Use glyphs_initialized_p instead.
2635 (FRAME_MESSAGE_BUF): Remove macro.
2636 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2637 * lisp.h (message2, message2_nolog): Remove declarations.
2638 (message3, message3_nolog): Update declarations.
2639 * keyboard.c (read_char_minibuf_menu_text)
2640 (read_char_minibuf_menu_width): Remove vars.
2641 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2642 to correctly handle multibyte strings.
2643 * frame.c (delete_frame): Don't free message_buf any more.
2644 * editfns.c (message_text, message_length): Remove vars.
2645 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2646 * fileio.c (auto_save_error): Use message3 instead of message2.
2647 * dispnew.c (adjust_frame_message_buffer): Remove function.
2649 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2651 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2652 real estate used for the tool bar and the menu bar.
2654 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2656 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2657 hidden buffer is prepared to modification (Bug#13164).
2659 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2661 * window.h (struct window): Change window_end_valid member from
2662 Lisp_Object to a bitfield. Adjust comments.
2663 (wset_window_end_valid): Remove.
2664 * window.c (adjust_window_count): Clear window_end_valid.
2665 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2666 (Fwindow_line_height, set_window_buffer, Frecenter)
2667 (Fsplit_window_internal, Fdelete_other_windows_internal)
2668 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2669 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2670 * xdisp.c (check_window_end, reconsider_clip_changes)
2671 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2672 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2673 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2675 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2677 * xdisp.c (mark_window_display_accurate): Simplify the loop
2678 assuming that the only one of vchild, hchild or buffer window
2679 slots is non-nil. Call mark_window_display_accurate_1 for
2680 the leaf windows only.
2681 (mark_window_display_accurate_1): Always assume leaf window.
2684 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2686 * emacs.c (Qkill_emacs_hook): Now static.
2688 * fileio.c (Finsert_file_contents): Simplify.
2689 Remove unnecessary assignments and tests.
2691 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2693 * w32.c (acl_set_file): Don't test for errors unless
2694 set_file_security returns FALSE. Avoids spurious errors when
2697 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2699 * fileio.c (Finsert_file_contents): Revert code introduced at
2700 2013-01-18 in favor of the simpler and generally better fix.
2701 Save stack space by removing 'buffer' and reusing 'read_buf'
2704 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2706 * lisp.h (eabs): Define unconditionally (Bug#13419).
2707 The old "#if !defined (eabs)" was an unnecessary revenant of back
2708 when this macro was called "abs". Document 'eabs' better.
2710 2013-01-19 Glenn Morris <rgm@gnu.org>
2712 * fns.c (Frandom): Doc fix.
2714 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2716 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2717 segfault when there are lots of overlays.
2719 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2720 when there are lots of overlays.
2721 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2722 for the details and a way to reproduce.
2724 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2726 * fileio.c: Use O_APPEND to append.
2727 This corresponds better to the natural interpretation of "append",
2728 and avoids the need to open the output file twice, or to invoke
2729 lseek when APPEND is neither nil nor a number.
2730 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2731 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2732 file possibly twice, and lseeking to its end; this avoids the
2733 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2734 at the same time: the combination is never needed and apparently
2735 it doesn't work with DOS_NT.
2737 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2738 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2740 Allow floating-point file offsets.
2741 Problem reported by Vitalie Spinu in
2742 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2743 * fileio.c (emacs_lseek): Remove.
2744 (file_offset): New function.
2745 (Finsert_file_contents, Fwrite_region): Use it.
2747 2013-01-19 Chong Yidong <cyd@gnu.org>
2749 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2750 aborting on Fsignal (Bug#13289).
2752 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2754 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2755 set_file_security as failure due to insufficient privileges.
2756 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2757 (fstat): Return owner and group like 'stat' and 'lstat' do.
2759 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2761 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2762 The bug was observed on Ubuntu operating inside a virtual machine,
2763 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2764 The workaround introduces a race condition on non-buggy hosts,
2765 but it's an unlikely race and anyway there's a nearly identical
2766 nearby race that can't be fixed.
2767 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2769 (Fwrite_region): Test for file system time stamp bug.
2770 (init_fileio): New function.
2771 * lisp.h (init_fileio): Declare it.
2772 * emacs.c (main): Call it.
2774 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2775 and make it more consistent with other stat-failure diagnostics.
2777 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2779 Fix crash when inserting data from non-regular files.
2780 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2781 for the error description produced by valgrind.
2782 * fileio.c (read_non_regular): Rename to read_contents.
2783 Free Lisp_Save_Value object used to pass parameters.
2784 (read_non_regular_quit): Rename to read_contents_quit.
2785 (Finsert_file_contents): Redesign internal file reading loop to adjust
2786 gap and end positions after each read and so help make_gap to work
2787 properly. Do not signal an I/O error too early and so do not leave

3247 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3249 * w32.c (acl_set_file): If setting the file security descriptor
3250 fails, and the new DACL is identical to the existing one, silently
3251 return success. This fixes problems for users backing up their
3252 own files without having the necessary privileges for setting
3253 security descriptors.
3255 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3257 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3258 after WaitForSingleObject returns normally. This expedites reader
3259 thread shutdown when delete_child triggers it.
3260 (reap_subprocess): More accurate commentary for why we call
3261 delete_child only when cp->fd is negative.
3263 * w32.c (sys_close): Do not call delete_child on a subprocess
3264 whose handle is not yet closed. Instead, set its file descriptor
3265 to a negative value, so that reap_subprocess will call
3266 delete_child on that subprocess when its SIGCHLD arrives.
3267 This avoids closing handles used for communications between sys_select
3268 and reader_thread, which doesn't give sys_select a chance to
3269 notice that the process exited and invoke the SIGCHLD handler for
3272 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3274 * nsfns.m (Fns_do_applescript): Run event loop until script has
3275 been executed (Bug#12969).
3276 (ns_run_ascript): Chech as_script for nil, set to nil after
3279 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3281 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3283 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3285 * w32term.c (w32fullscreen_hook): New function.
3286 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3288 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3290 * fileio.c (Finsert_file_contents): Doc fix.
3292 * w32proc.c (new_child, delete_child, find_child_pid): For a
3293 subprocess, consider its slot being in use as long as its process
3294 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3295 slot when a new process is started immediately after killing
3296 another one, without waiting enough time for the first process to
3297 be reaped and resources allocated for it be orderly freed.
3299 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3301 2012-12-21 Chong Yidong <cyd@gnu.org>
3303 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3305 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3307 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3309 * w32.c (get_name_and_id): Always pass NULL as the first argument
3310 of lookup_account_sid. Avoids crashes with UNC file names that
3311 refer to DFS domains, not to specific machine names. (Bug#12621)
3312 Remove now unused argument FNAME; all callers changed.
3313 (get_file_owner_and_group): Remove now unused argument FNAME; all
3316 2012-12-21 Chong Yidong <cyd@gnu.org>
3318 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3319 error for invalid chars, don't check for a nil return value.
3321 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3323 Avoid calls to CHAR_TO_BYTE if byte position is known.
3324 * editfns.c (make_buffer_string_both): Use move_gap_both.
3325 (Fbuffer_string): Use make_buffer_string_both.
3326 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3328 (buf_bytepos_to_charpos): Likewise.
3329 (charpos_to_bytepos): Remove.
3330 * fileio.c (Finsert_file_contents): Use move_gap_both.
3331 * search.c (Freplace_match): Likewise.
3332 * process.c (process_send_region): Likewise. Use convenient
3333 names for byte positions.
3334 * lisp.h (charpos_to_bytepos): Remove prototype.
3335 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3336 * insdel.c (move_gap): Likewise.
3338 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3340 * xdisp.c (redisplay_internal): Remove now-unused local.
3342 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3344 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3345 (redisplay_internal): Don't bother selecting the frame to get the
3346 proper value of frame-local variables (bug#13225).
3348 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3350 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3351 Rename 4th argument since it may be buffer or string. Adjust comment.
3352 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3354 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3356 * coding.c (Fdetect_coding_region): Do not check start and end with
3357 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3358 (code_convert_region): Likewise.
3360 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3362 * w32.c (acl_get_file, acl_set_file): Run the file name through
3363 map_w32_filename, and resolve any symlinks in the file name, like
3365 (acl_set_file): Call revert_to_self, if any privileges were
3368 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3370 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3371 ($(BLD)/w32.$(O)): Update dependencies.
3373 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3375 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3376 propagate redisplay's scrolling (if any) to the right window.
3377 (redisplay_internal): Use ensure_selected_frame.
3378 (display_mode_lines): Complete last fix.
3379 * window.c (select_window_1): New func, extracted from select_window.
3380 (select_window): Use it.
3381 * window.h (select_window_1): Declare.
3383 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3385 Emulate Posix ACL APIs on MS-Windows.
3386 * w32.c: Include sddl.h and sys/acl.h.
3387 (SDDL_REVISION_1): Define if not already defined.

3403 (acl_free, acl_get_file, acl_set_file): New functions.
3405 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3407 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3409 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3410 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3411 for some of that bug's symptoms can now cause Emacs to abort.
3412 Remove the workaround.
3413 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3414 The bug that caused SIGCHLD to get lost has been fixed, and the
3415 workaround for it can now cause Emacs to abort.
3417 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3419 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3420 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3421 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3423 2012-12-16 Romain Francoise <romain@orebokech.com>
3425 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3426 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3427 and copy ACL entries of file in addition to SELinux context if set.
3428 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3430 * Makefile.in (LIBACL_LIBS): New macro.

3435 * fileio.c (internal_delete_file): Use bool for boolean.
3437 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3439 Fix bug #13079 on MS-Windows with temp files not being deleted.

3445 * w32proc.c (new_child): Initialize input_file and
3446 pending_deletion members of the child.
3447 (delete_child): Delete the child's temporary input file, if any,
3448 that is pending deletion.
3449 (register_child): First argument is now pid_t.
3450 (record_infile, record_pending_deletion): New functions.
3451 (reap_subprocess): Fix a typo in DebPrint string.
3452 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3454 * fileio.c (internal_delete_file): Return an int again: non-zero
3455 if delete-file succeeds, zero otherwise.
3457 * lisp.h (internal_delete_file): Adjust prototype.
3459 * callproc.c (Fcall_process): Don't overwrite infile with result
3461 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3462 asynchronous subprocess, record the name of the input file name,
3464 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3465 delete the file, record it as pending deletion when the subprocess
3468 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3470 * editfns.c [HAVE_PWD_H]: Include grp.h.
3472 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

3476 Fix permissions bugs with setgid directories etc. (Bug#13125)
3477 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3478 to mark it as a placeholder. The old value was often wrong.
3479 The only user of this attribute has been changed to use
3480 file-ownership-preserved-p instead, with its new group arg.
3481 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3483 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

3488 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3490 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3491 try to get accurate owner and group information from NT file
3492 security APIs. This is to make most callers of 'stat' and
3493 'lstat', which don't need that information, much faster.
3495 * dired.c (Ffile_attributes) [WINDOWSNT]:
3496 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3497 owner and group information from 'lstat'.
3499 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3501 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3502 as that confuses set-auto-coding, so insist on the head-read
3503 returning the full 1024 bytes. Let lseek compute the tail offset;
3504 less work for us. Do not ignore I/O errors when reading the tail.
3506 * xdisp.c: Minor style fixes.
3507 (init_iterator): Hoist assignment out of if-expression.
3508 (markpos_of_region): Callers now test for sign, not for -1.

3514 (init_iterator): Do not highlight the region of zero length.
3515 (redisplay_window): Check whether the region is of non-zero length.
3516 (try_cursor_movement): Allow if the region length is zero.

3521 * search.c (search_buffer): Check the inverse translations of each
3522 character in pattern when the buffer being searched is unibyte.
3525 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3527 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3528 files, fixing a regression from 24.2.
3529 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3531 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3533 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3534 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3535 Remove unnecessary S_ISLNK test, as (contra the comments) this
3536 function can't copy symlinks. Improve quality of error message
3537 when attempting to copy files that are neither regular files nor

3546 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3548 2012-12-12 Daniel Colascione <dancol@dancol.org>
3550 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3551 the dumped Emacs is not a sparse file, greatly improving Cygwin
3552 "make bootstrap" performance.
3554 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3556 * inotify.c (inotify_callback): Generate an Emacs event for every
3557 incoming inotify event.
3559 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3561 * xdisp.c (handle_face_prop): Fix logic of computing
3562 it->start_of_box_run_p.
3563 (append_space_for_newline): If the glyph row is R2L, reset the
3564 iterator's end_of_box_run_p flag before prepending the space glyph.
3565 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3566 iterator's start_of_box_run_p flag before prepending the stretch.
3567 (append_glyph, produce_image_glyph, append_composite_glyph)
3568 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3569 left_box_line_p and right_box_line_p flags of the glyph for R2L
3570 glyph rows. (Bug#13011)
3572 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

3577 * window.c (replace_buffer_in_windows_safely): Do nothing
3578 if buffer is not shown in a window.

3585 encoded_file_name, which is what it is.
3587 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

3619 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3620 (hinst): Remove unneeded extern declaration.
3621 (_start): Remove initialization of above variables; remove
3622 initialization of hinst, as cache_system_info now does that.

3731 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
3733 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
3735 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
3736 DWORD_PTR, for compatibility with 64-bit builds.
3738 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
3739 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
3740 (system_process_attributes): Use SIZE_T rather than DWORD, for
3741 compatibility with 64-bit builds.

3747 2012-12-10 Eli Zaretskii <eliz@gnu.org>
3749 * indent.c (Fvertical_motion): If a display string will be
3750 displayed on the left or the right margin, don't consider it as a
3751 factor in cursor positioning. (Bug#13108)
3753 2012-12-10 Martin Rudalics <rudalics@gmx.at>
3755 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
3757 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

3762 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3764 * w32.c (unsetenv): Return 0 if the input string is too long.
3766 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3768 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3769 * alloc.c (xputenv): New function.
3770 * dbusbind.c (Fdbus_init_bus):
3772 * xterm.c (x_term_init):
3773 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
3774 * editfns.c (initial_tz): Move static var decl up.
3775 (tzvalbuf_in_environ): New static var.
3776 (init_editfns): Initialize these two static vars.
3777 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
3778 Save old TZ value on stack, if it's small.
3779 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
3780 instead, use xputenv+unsetenv to set and restore TZ.
3781 (environbuf): Remove static var. All uses removed.
3782 (Fset_time_zone_rule): Do not save TZ and environ;
3783 no longer needed here.
3784 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3785 Move to inside set_time_zone_rule; they don't need file scope any more.
3786 (set_time_zone_rule): Maintain the TZ=value string separately.
3787 (syms_of_editfns): Don't initialize initial_tz;
3788 init_editfns now does it.
3789 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3790 * lisp.h (xputenv): New decl.
3792 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3794 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3796 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3798 * w32.c (unsetenv, sys_putenv): New functions.
3800 2012-12-08 Chong Yidong <cyd@gnu.org>
3802 * editfns.c (Finsert_char): Make the error message more
3803 informative (Bug#12992).
3805 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3807 Simplify get_lim_data.
3808 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3809 Remove USG and vlimit methods; no longer used these days.
3810 Add #error catchall just in case.
3812 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3813 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3814 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3815 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3816 (deleted_pid_list, Fdelete_process, create_process)
3817 (record_child_status_change, handle_child_signal, deliver_child_signal)
3818 (init_process_emacs, syms_of_process):
3819 Assume SIGCHLD is defined.
3820 (parse_signal): Remove. All uses removed.
3821 (abbr_to_signal): New static function.
3822 (Fsignal_process): Use it to convert signal names to ints.
3823 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3824 kill (getpgrp (), ...).
3825 (emacs_sigaction_init): Assume SIGCHLD is defined.
3826 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3827 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

3829 All uses replaced by 'kill' with a negative pid.
3830 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3831 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3833 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3835 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3836 This will cause a production Emacs to dump core instead of
3839 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3841 * frame.c (make_frame): Do not set window's buffer to t.
3842 * window.c (Fsplit_window_internal): Likewise. Previously it was
3843 used to indicate that the window is being set up. Now we use
3844 set_window_buffer for all new windows, so the condition in ...
3845 (Fset_window_buffer): ... is always true and can be removed.
3847 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3849 Convenient macro to check whether the buffer is hidden.
3850 * buffer.h (BUFFER_HIDDEN_P): New macro.
3851 * frame.c (make_frame): Use it. Adjust comment.
3852 * buffer.c (candidate_buffer): New function.
3853 (Fother_buffer, other_buffer_safely): Use it.
3855 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3857 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3858 if the child process is still running. Instead, exit the wait
3859 loop and return zero. (Bug#13086)
3861 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3863 * frame.h (x_char_width, x_char_height): Remove prototypes.

3877 * callproc.c, process.h (record_kill_process):
3878 New function, containing part of the old call_process_kill.
3879 (call_process_kill): Use it.
3880 This does not change call_process_kill's behavior.
3881 * process.c (Fdelete_process): Use record_kill_process to fix a
3882 race condition that could cause Emacs to lose track of a child.
3884 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3886 Avoid code duplication between prev_frame and next_frame.
3887 * frame.c (candidate_frame): New function. Add comment.
3888 (prev_frame, next_frame): Use it. Adjust comment.
3890 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3892 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3893 fails, signal an error instead of continuing with an empty
3895 Encode expanded temp file pattern before passing it to mkstemp or
3898 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3899 Encode the file name before passing it to dostounix_filename, in
3900 case it will downcase it (under w32-downcase-file-names).
3903 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3905 Minor call-process cleanups.
3906 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3907 at the same time as other platforms, to simplify analysis.
3908 No need for fd0_volatile since we have synch_process_fd.
3909 Avoid needless emacs_close; arg is always negative.
3911 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3913 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3916 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3918 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3919 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3920 and mouse_face_hidden members to a bitfields.
3921 * frame.h (struct frame): Remove set-but-not-used space_width member.
3922 (FRAME_SPACE_WIDTH): Remove.
3923 * nsterm.m, w32term.c, xterm.c: Adjust users.
3924 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3925 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3926 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3927 members to a bitfields.
3929 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3931 Don't let call-process be a zombie factory (Bug#12980).
3932 Fixing this bug required some cleanup of the signal-handling code.
3933 As a side effect, this change also fixes a longstanding rare race
3934 condition whereby Emacs could mistakenly kill unrelated processes,
3935 and it fixes a bug where a second C-g does not kill a recalcitrant
3936 synchronous process in GNU/Linux and similar platforms.
3937 The patch should also fix the last vestiges of Bug#9488,
3938 a bug which has mostly been fixed on the trunk by other changes.
3939 * callproc.c, process.h (synch_process_alive, synch_process_death)
3940 (synch_process_termsig, sync_process_retcode):
3941 Remove. All uses removed, to simplify analysis and so that
3942 less consing is done inside critical sections.
3943 * callproc.c (call_process_exited): Remove. All uses replaced
3944 with !synch_process_pid.
3945 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3946 These take the role of what used to be in unwind-protect arg.
3948 (block_child_signal, unblock_child_signal):
3949 New functions, to avoid races that could kill innocent-victim processes.
3950 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3951 (call_process_kill): Record killed processes as deleted, so that
3952 zombies do not clutter up the system. Do this inside a critical
3953 section, to avoid a race that would allow the clutter.
3954 (call_process_cleanup): Fix code so that the second C-g works again
3955 on common platforms such as GNU/Linux.
3956 (Fcall_process): Create the child process in a critical section,
3957 to fix a race condition. If creating an asynchronous process,
3958 record it as deleted so that zombies do not clutter up the system.
3959 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3960 light of these changes. Omit unnecessary call to emacs_close
3961 before failure, as the unwind-protect code does that.
3962 * callproc.c (call_process_cleanup):
3963 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3964 * process.c (record_deleted_pid): New function, containing
3965 code refactored out of Fdelete_process.
3966 (Fdelete_process): Use it.
3967 (process_status_retrieved): Remove. All callers changed to use
3968 child_status_change.
3969 (record_child_status_change): Remove, folding its contents into ...
3970 (handle_child_signal): ... this signal handler. Now, this
3971 function is purely a handler for SIGCHLD, and is not called after
3972 a synchronous waitpid returns; the synchronous code is moved to
3973 wait_for_termination. There is no need to worry about reaping
3974 more than one child now.
3975 * sysdep.c (get_child_status, child_status_changed): New functions.
3976 (wait_for_termination): Now takes int * status and bool
3977 interruptible arguments, too. Do not record child status change;
3978 that's now the caller's responsibility. All callers changed.
3979 Reimplement in terms of get_child_status.
3980 (wait_for_termination_1, interruptible_wait_for_termination):
3981 Remove. All callers changed to use wait_for_termination.
3982 * syswait.h: Include <stdbool.h>, for bool.
3983 (record_child_status_change, interruptible_wait_for_termination):
3985 (record_deleted_pid, child_status_changed): New decls.
3986 (wait_for_termination): Adjust to API changes noted above.
3988 * bytecode.c, lisp.h (Qbytecode): Remove.
3989 No longer needed after 2012-11-20 interactive-p changes.
3991 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3993 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3994 the scroll margin, move point outside the margin. (Bug#13055)
3996 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3998 * gtkutil.c (my_log_handler): New function.
3999 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4001 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4003 * lisp.h (modify_region): Rename to...
4004 (modify_region_1): ...new prototype.
4005 * textprop.c (modify_region): Now static. Adjust users.
4006 * insdel.c (modify_region): Rename to...
4007 (modify_region_1): ...new function to work with current buffer.
4008 Adjust comment and users. Use true and false for booleans.
4010 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4012 * alloc.c (free_save_value): New function.
4013 (safe_alloca_unwind): Use it.
4014 * lisp.h (free_save_value): New prototype.
4015 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4017 (save_excursion_restore): Adjust to match saved data structure.
4018 Use free_save_value to offload some work from GC. Drop obsolete
4021 2012-12-03 Chong Yidong <cyd@gnu.org>
4023 * fileio.c (Vauto_save_list_file_name): Doc fix.
4025 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4027 * w32fns.c: Remove prototype of atof.
4028 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
4030 (file_dialog_callback): Make it UINT_PTR.
4032 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
4035 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4036 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
4039 2012-12-03 Glenn Morris <rgm@gnu.org>
4041 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
4043 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
4045 Fix xpalloc confusion after memory is exhausted.
4046 * alloc.c (xpalloc): Comment fix.
4047 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4048 and signals an error, do not clear charset_table_size, as
4049 charset_table is still valid.
4050 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4052 Use execve to avoid need to munge environ (Bug#13054).
4053 * callproc.c (Fcall_process):
4054 * process.c (create_process):
4055 Don't save and restore environ; no longer needed.
4056 * callproc.c (child_setup):
4057 Use execve, not execvp, to preserve environ.
4059 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4061 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
4063 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4065 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
4066 display for sliced images (Bug#10500).
4068 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
4070 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
4072 * doc.c (Fdocumentation): Re-add handling of function-documentation,
4073 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4075 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4077 * xdisp.c (window_outdated): Remove eassert since it hits
4078 some suspicious corner cases (see Bug#13007 and Bug#13012).
4079 (mode_line_update_needed): New function.
4080 (redisplay_internal, redisplay_window): Use it.
4081 (ensure_selected_frame): New function.
4082 (redisplay_internal, unwind_redisplay): Use it.
4083 (redisplay_internal): Move comment about buffer_shared...
4084 (buffer_shared_and_changed): ...near to its real use.
4086 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
4088 * callproc.c (Fcall_process): Don't misreport vfork failure.
4090 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4092 * callproc.c (Fcall_process): Fix vfork portability problems.
4093 Do not assume that fd[0], count, filefd, and save_environ survive
4094 vfork. Fix bug whereby wrong errno value could be reported for
4095 pipe failure. Some minor cleanups, too, as follows. Move buf and
4096 bufsize to the context where they're needed. Change new_argv to
4097 be of type char **, as this is more convenient and avoids casts.
4098 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4099 Now local constants, not macros.
4101 2012-11-18 Kenichi Handa <handa@gnu.org>
4103 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
4104 for the variable "f".
4106 2012-11-13 Kenichi Handa <handa@gnu.org>
4108 * font.c (font_unparse_xlfd): Exclude special characters from the
4109 generating XLFD name.
4111 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
4113 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

4124 * lread.c (readbyte_from_file): Assume EINTR is defined.
4125 * process.c (wait_reading_process_output, send_process) [subprocesses]:
4126 Assume EIO and EAGAIN are defined.
4127 * unexcoff.c (write_segment): Assume EFAULT is defined.
4129 2012-11-27 Eli Zaretskii <eliz@gnu.org>
4131 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
4134 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
4135 highlighting on the frame was cleared. Prevents assertion
4136 violations when repeatedly clicking on the "Top" link of the
4137 "bread-crumbs" in Info buffers.
4139 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

4146 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
4147 were always defined.
4149 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4151 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4152 between bpos_covered and bpos_max. This fixes cursor display when
4153 several display strings follow each other.
4155 * .gdbinit (pgx): If the glyph's object is a string, display the
4156 pointer to string data, rather than the value of the string object
4157 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4159 * indent.c (Fvertical_motion): If the starting position is covered
4160 by a display string, return to one position before that, to avoid
4161 overshooting it inside move_it_to. (Bug#12930)
4163 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4165 * frame.h (struct frame): Remove display_preempted member

4168 * w32menu.c (pending_menu_activation): Remove since not
4170 (set_frame_menubar): Adjust user.
4171 * w32term.h (struct x_output): Drop outdated #if 0 code.
4172 (struct w32_output): Use bitfields for explicit_parent,
4173 asked_for_visible and menubar_active members.
4174 Drop unused pending_menu_activation member.
4175 * xterm.h (struct x_output): Drop outdated #if 0 code.
4176 Use bitfields for explicit_parent, asked_for_visible,
4177 has_been_visible and net_wm_state_hidden_seen members.
4179 2012-11-23 Eli Zaretskii <eliz@gnu.org>
4181 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4182 of a literal "/". (Bug#12955)
4183 (gl-stamp): Invoke fc.exe directly, not through cmd.
4185 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4187 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4188 * dired.c: Assume HAVE_DIRENT_H.
4189 (NAMLEN): Remove, replacing with ...
4190 (dirent_namelen): New function. All uses changed. Use the GNU macro
4191 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4192 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4193 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4194 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4196 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4197 * ndir.h: Rename to ../nt/inc/dirent.h.
4198 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4199 Do not include <dirent.h>; no longer needed.
4200 * w32.c: Include <dirent.h> rather than "ndir.h".
4202 2012-11-23 Chong Yidong <cyd@gnu.org>
4204 * xftfont.c (xftfont_open): Remove duplicate assignment.
4206 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4208 * alloc.c (Fgarbage_collect): Unblock input after clearing
4209 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4210 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4211 * msdos.c (IT_frame_up_to_date): Use it here...
4212 * w32term.c (w32_frame_up_to_date): ...here...
4213 * xterm.c (XTframe_up_to_date): ...and here...
4214 * nsterm.m (ns_frame_up_to_date): ...but not here.
4215 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4217 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4218 Do not check whether GC is in progress.
4220 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4222 * xdisp.c (window_buffer_changed): New function.
4223 (update_menu_bar, update_tool_bar): Use it to
4224 simplify large 'if' statements.
4225 (redisplay_internal): Generalize commonly used
4226 'tail' and 'frame' local variables.
4228 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4230 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4231 with Windows system header.
4233 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4235 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4236 * alloc.c: Assume unistd.h exists.
4237 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4238 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4239 (getwd) [USG]: Remove; no longer needed.
4240 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4241 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4242 * w32.h (getcwd): Remove decl.
4244 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4246 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4247 Make it set selected_window as well.
4248 (update_tool_bar): Use it.
4250 2012-11-21 Ken Brown <kbrown@cornell.edu>
4252 * emacs.c (main): Set the G_SLICE environment variable for all
4253 Cygwin builds, not just GTK builds. See
4254 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4256 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4258 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4259 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4260 Define for the MSVC compiler.
4262 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4264 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4265 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4266 dostounix_filename. Prevents crashes down the road, because
4267 dostounix_filename assumes it gets a unibyte string.
4268 Reported by Michel de Ruiter <michel@sentient.nl>, see
4269 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
4271 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

4275 * lread.c (init_obarray): Set `function' fields to Qnil.
4276 * eval.c (Fcommandp): Ignore Qunbound.
4277 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
4278 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
4279 Test NILP rather than Qunbound.
4280 (Ffmakunbound): Set to Qnil.
4281 (Fsymbol_function): Never signal an error.
4282 (Finteractive_form): Ignore Qunbound.
4284 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
4286 * eval.c (interactive_p): Remove no-longer-used decl.
4288 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4290 * xdisp.c (buffer_shared): Adjust comment.
4291 (buffer_shared_and_changed): New function.
4292 (prepare_menu_bars, redisplay_internal): Use it to
4293 decide whether all windows or frames should be updated.
4294 (window_outdated): New function.
4295 (text_outside_line_unchanged_p, redisplay_window): Use it.
4296 (redisplay_internal): Likewise. Fix indentation.
4298 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4300 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4301 (syms_of_eval): Remove corresponding defsubr.
4302 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4304 2012-11-19 Daniel Colascione <dancol@dancol.org>
4306 * w32fns.c (Fx_file_dialog):
4307 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4308 cygwin_convert_file_name*.
4310 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4311 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4313 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4315 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4317 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4319 * w32select.c: Include w32common.h before w32term.h, so that
4320 windows.h gets included before w32term.h uses some of its
4321 features, see below.
4323 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4325 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4327 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4329 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4331 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4332 (ns_select): Return at once if events are held (Bug#12834).
4334 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4336 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4337 Needed following 2012-10-20 change. (Bug#12902)
4339 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4341 * w32proc.c (waitpid): Remove unused label get_result.
4343 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4345 * makefile.w32-in (SYSWAIT_H): New macro.
4346 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4347 ($(BLD)/sysdep.$(O)): Update dependencies.
4349 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4351 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4352 * callproc.c (relocate_fd): Assume F_DUPFD.
4353 * emacs.c, term.c (O_RDWR): Remove.
4354 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4355 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4356 * nsterm.m: Assume <fcntl.h> exists.
4357 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4358 (create_pty, Fmake_network_process, server_accept_connection)
4359 (wait_reading_process_output, init_process_emacs):
4361 (wait_reading_process_output): Put in a special case for WINDOWSNT
4362 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4363 It's not clear this is needed, but it's a more-conservative change.
4364 (create_process): Assume FD_CLOEXEC.
4365 (create_process, create_pty): Assume O_NOCTTY.
4366 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4367 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4368 Omit if not DOS_NT, since F_GETFL is not defined there.
4369 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4370 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4372 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4373 lack it, since gnulib guarantees this.
4374 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4376 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4378 * w32.c (faccessat): Pretend that directories have the execute bit
4379 set. Emacs expects that, e.g., in files.el:cd-absolute.
4381 * w32proc.c (create_child): Don't clip the PID of the child
4382 process to fit into an Emacs integer, as this is no longer a
4384 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4385 reaping only the process specified by PID argument, if that is
4386 positive. Use PID instead of dead_child to know which process to
4387 reap. Wait for the child to die only if WNOHANG is not in
4389 (sys_select): Don't set dead_child.
4391 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4392 as it is no longer needed.
4394 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4396 (record_child_status_change): Remove the setting of
4397 record_at_most_one_child for the !WNOHANG case.
4399 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4401 Fix problems in ns port found by static checking.
4402 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4403 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4404 not to process group.
4405 (ns_select): Use emacs_write, not write, as that's more robust
4406 in the presence of signals.
4407 (fd_handler:): Check for read errors.
4409 2012-11-16 Glenn Morris <rgm@gnu.org>
4411 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4413 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4415 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4417 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4419 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4420 use the same value of thread handle.
4421 (start_timer_thread): If the timer thread exited (due to error),
4422 clean up by closing the two handles it used. Duplicate the caller
4423 thread's handle here, so it gets duplicated only once, when
4424 launching the timer thread. Set priority of the timer thread, not
4426 (getitimer): Don't duplicate the caller thread's handle here.
4429 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4431 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4434 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4436 Remove no-longer-used pty_max_bytes variable.
4437 * process.c (pty_max_bytes): Remove; unused.
4438 (send_process): Do not set it.
4440 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4442 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4443 Update dependencies.
4445 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4447 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4448 This follows up on the 2012-09-29 patch that removed indirection
4449 for the 'function' field. Reported by Sergey Vinokurov in
4450 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4452 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4454 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4455 different name, as the MS runtime does not have such a function,
4456 and probably never will.) All callers changed. Ignore DIRFD
4457 value if PATH is an absolute file name, to match Posix spec
4458 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4461 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4463 * xdisp.c (echo_area_display, redisplay_internal):
4464 Omit redundant check whether frame_garbaged is set.
4466 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4468 Use faccessat, not access, when checking file permissions (Bug#12632).
4469 This fixes a bug that has been present in Emacs since its creation.
4470 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4471 which must set some sort of record. (Torek's bug report was against
4472 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4473 same common flaw.) See Torek's Usenet posting
4474 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4475 Posted: Fri Apr 8 14:18:56 1983.
4476 * Makefile.in (LIB_EACCESS): New macro.
4478 * callproc.c (init_callproc):
4479 * charset.c (init_charset):
4480 * fileio.c (check_existing, check_executable, check_writable)
4482 * lread.c (openp, load_path_check):
4483 * process.c (allocate_pty):
4485 Use effective UID when checking permissions, not real UID.
4486 * callproc.c (init_callproc):
4487 * charset.c (init_charset):
4488 * lread.c (load_path_check, init_lread):
4489 Test whether directories are accessible, not merely whether they exist.
4490 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4491 * fileio.c (check_existing, check_executable, check_writable)
4493 Use symbolic names instead of integers for the flags, as they're
4495 (check_writable): New arg AMODE. All uses changed.
4496 Set errno on failure.
4497 (Ffile_readable_p): Use faccessat, not stat + open + close.
4498 (Ffile_writable_p): No need to call check_existing + check_writable.
4499 Just call check_writable and then look at errno. This saves a syscall.
4500 dir should never be nil; replace an unnecessary runtime check
4501 with an eassert. When checking the parent directory of a nonexistent
4502 file, check that the directory is searchable as well as writable, as
4503 we can't create files in unsearchable directories.
4504 (file_directory_p): New function, which uses 'stat' on most platforms
4505 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4506 (Ffile_directory_p, Fset_file_times): Use it.
4507 (file_accessible_directory_p): New function, which uses a single
4508 syscall for efficiency.
4509 (Ffile_accessible_directory_p): Use it.
4510 * xrdb.c (file_p): Use file_directory_p.
4511 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4512 * lread.c (openp): When opening a file, use fstat rather than
4513 stat, as that avoids a permissions race. When not opening a file,
4514 use file_directory_p rather than stat.
4515 (dir_warning): First arg is now a usage string, not a format.
4516 Use errno. All uses changed.
4517 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4518 that merely introduced a race.
4519 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4520 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4521 and similarly for the other O_* flags.
4522 * w32.c (sys_faccessat): Rename from sys_access and switch to
4523 faccessat's API. All uses changed.
4524 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4525 (magic_db): Rename from magic_file_p.
4526 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4527 char *, so that we don't have to test for file existence
4528 separately from opening the file for reading. This removes a race
4529 fixes a permission-checking problem, and simplifies the code.
4531 (file_p): Remove; no longer needed.
4533 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4535 Omit glyphs initialization at startup.
4536 * dispnew.c (glyphs_initialized_initially_p): Remove.
4537 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4538 (Fredraw_frame): Move actual code from here...
4539 (redraw_frame): ...to here. Add eassert. Adjust comment.
4540 (Fredraw_display): Use redraw_frame.
4541 * xdisp.c (clear_garbaged_frames): Likewise.
4543 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4545 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4546 passed to pint2str and pint2hrstr to be at most the size of the
4547 frame's decode_mode_spec_buffer. This avoids crashes with very
4548 large values of FIELD_WIDTH argument to decode_mode_spec.
4551 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4553 Fix a race with verify-visited-file-modtime (Bug#12863).
4554 Since at least 1991 Emacs has ignored an mtime difference of no
4555 more than one second, but my guess is that this was to work around
4556 file system bugs that were fixed long ago. Since the race is
4557 causing problems now, let's remove that code.
4558 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4559 whose time stamp is off by no more than a second. Insist that the
4560 file time stamps match exactly.
4562 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4564 * frame.h (struct frame): Convert external_tool_bar member to
4565 1-bit unsigned bitfield.
4566 * termhooks.h (struct terminal): Remove mouse_moved member since
4567 all users are long dead. Adjust comment on mouse_position_hook.
4569 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4571 Simplify by using FOR_EACH_FRAME here and there.
4572 * frame.c (next_frame, prev_frame, other_visible_frames)
4573 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4574 * w32term.c (x_window_to_scroll_bar): Likewise.
4575 * window.c (window_list): Likewise.
4576 * xdisp.c (x_consider_frame_title): Likewise.
4577 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4578 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4579 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4580 * xmenu.c (menubar_id_to_frame): Likewise.
4581 * xselect.c (frame_for_x_selection): Likewise.
4582 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4583 (x_window_to_menu_bar): Likewise.
4584 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4586 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4588 * data.c (Qdefalias_fset_function): Now static.
4590 Another tweak to vectorlike_header change.
4591 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4592 Remove, and replace all uses with ...
4593 (next_in_free_list, set_next_in_free_list):
4594 New functions, which respect C's aliasing rules better.
4596 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4598 * window.c (list4i): Rename from 'quad'. All uses changed.
4599 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4601 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4603 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4604 warning about mixing declarations and code in ISO C90.
4606 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4608 * window.c (Fsplit_window_internal): Set combination limit of
4609 new parent window to t iff Vwindow_combination_limit is t;
4610 fixing a regression introduced with the change from 2012-09-22.
4611 (Fset_window_combination_limit): Fix doc-string.
4613 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4615 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4616 amount when the scroll margins are too large. When scrolling
4617 backwards in the buffer, give up if cannot reach point or the
4618 scroll margin within a reasonable number of screen lines.
4619 Fixes point position in window under scroll-up/down-aggressively when
4620 point is positioned many lines beyond the window top/bottom.
4623 * ralloc.c (relinquish): If real_morecore fails to return memory
4624 to the system, don't crash; instead, leave the last heap
4625 unchanged and return. (Bug#12774)
4627 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4629 * lisp.h (AUTOLOADP): New macro.
4630 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4631 * data.c (Ffset): Remove special ad-advice-info handling.
4632 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4634 (Finteractive_form): Simplify.
4635 (Fquo): Don't insist on having at least 2 arguments.

4655 Tweak last vectorlike_header change.
4656 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4657 vectorlike object on the free list. This is introduced to avoid
4658 some (but not all) pointer casting and aliasing problems, see
4659 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4660 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4664 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4666 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

4692 special hash function containing a comparison that always yields 1.
4694 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4696 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4697 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4698 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4701 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4703 * image.c (xpm_make_color_table_h): Fix compiler error because
4704 make_hash_table changed.
4706 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4708 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4710 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4712 Use ad-hoc comparison function for the profiler's hash-tables.
4713 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4714 (make_log): Use them.
4715 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4716 call Fequal any more.

4725 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4726 (hash_lookup, hash_remove_from_table): Move assertion checking of
4727 hashfn result here. Check hash-equality before calling cmpfn.

4740 value of w32-scroll-lock-modifier is neither nil nor one of the
4741 known key modifiers. (Bug#12806)
4743 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4745 Shrink struct vectorlike_header to the only size field.
4746 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4748 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4749 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

4751 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4752 information from the vector header. Adjust comment.

4769 (allocate_vector_from_block): Simplify.
4770 (PSEUDOVECTOR_NBYTES): Replace with...

4773 (allocate_vectorlike): Likewise.
4774 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4775 Add easserts. Adjust XSETPVECTYPESIZE usage.
4776 (allocate_buffer): Use BUFFER_PVEC_INIT.
4777 (live_vector_p): Adjust to match large vector.
4778 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4779 * buffer.h (struct buffer): Add next member.
4780 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4782 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4788 (xvecsize): New command.
4790 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4792 * keyboard.c (event_to_kboard): Do not dereference
4793 frame_or_window field of SELECTION_REQUEST_EVENT
4794 and SELECTION_CLEAR_EVENT events (Bug#12814).
4795 * xterm.h (struct selection_input_event): Adjust comment.
4797 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4799 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4800 such as Scroll Lock, if the respective keys are treated as
4801 function keys, not as modifiers. This avoids destroying non-ASCII
4802 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4804 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4806 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4808 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4810 Restore some duplicate definitions (Bug#12814).
4811 This undoes part of the 2012-11-03 changes. Some people build
4812 with plain -g rather than with -g3, and they need the duplicate
4813 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4814 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4815 Define as macros, as well as as enums or as constants.
4817 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4819 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4820 to keypad keys (Bug#12816).
4822 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4824 Minor adjustments of recently-changed frame functions.
4825 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4826 known to be a frame (we're in the FRAMEP branch).
4827 * lisp.h (Qframep): Remove decl. frame.h declares this.
4828 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4829 since they're meant for Lisp fixnum values.
4831 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4833 * window.c (Fwindow_combination_limit): Revert to the only
4834 required argument and adjust docstring as suggested in
4835 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4836 by Martin Rudalics <rudalics@gmx.at>.
4838 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4840 Widely used frame validity and checking functions.
4841 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4842 * frame.c (decode_live_frame, decode_any_frame): New functions.
4843 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4844 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4845 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

4853 * lisp.h (frame_buffer_predicate): Remove prototype.
4854 * buffer.c (Fother_buffer): Use decode_any_frame.
4855 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4856 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4857 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4858 (Fclose_font, Ffont_info): Use decode_live_frame.
4859 * fontset.c (check_fontset_name): Likewise.
4860 * terminal.c (Fframe_terminal): Likewise.
4861 * w32fns.c (check_x_frame): Likewise.
4862 * window.c (Fminibuffer_window, Fwindow_at)
4863 (Fcurrent_window_configuration): Likewise.
4864 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4865 Likewise. Allow zero number of arguments. Adjust docstring.
4866 * dispnew.c (Fredraw_frame): Likewise.
4867 * xfaces.c (frame_or_selected_frame): Remove.
4868 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4869 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4870 (Fframe_face_alist): Use decode_live_frame.
4871 * xfns.c (check_x_frame): Likewise.
4873 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4875 * window.c (quad): New function.
4876 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4877 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4878 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4879 (Fwindow_line_height): Use it.
4880 (Fwindow_fringes): Use list3.
4881 (Fwindow_scroll_bars): Use list4.
4882 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4883 (Fwindow_combination_limit): Allow zero number of arguments.
4885 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4887 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4889 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4890 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4891 file descriptor 2 for standard error. (Bug#12805)
4893 2012-11-05 Chong Yidong <cyd@gnu.org>
4895 * process.c (wait_reading_process_output): Revert previous change.
4897 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4899 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4900 This removes code that has been obsolete since around 1990.
4901 * callproc.c (Fcall_process):
4903 * process.c (create_process):
4904 * term.c (dissociate_if_controlling_tty):
4905 Assume setsid exists.
4906 * callproc.c (child_setup): Assume setpgid exists and behaves as
4907 per POSIX.1-1988 or later.
4908 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4909 * emacs.c (shut_down_emacs):
4910 * sysdep.c (sys_suspend, init_foreground_group):
4911 Assume getpgrp behaves as per POSIX.1-1998 or later.
4912 * msdos.c (setpgrp): Remove.
4913 (tcgetpgrp, setpgid, setsid): New functions.
4914 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4915 * term.c (no_controlling_tty): Remove; unused.
4916 * w32proc.c (setpgrp): Remove.
4917 (setsid, tcgetpgrp): New functions.
4919 Simplify by assuming __fpending.
4920 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4921 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4922 Do not assume that __fpending's result fits in int.
4924 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4926 Remove EMACS_OUTQSIZE+sleep hack.
4927 * dispnew.c (update_frame_1): Remove hack for terminals slower
4928 than 2400 bps, which throttled Emacs by having it sleep.
4929 This code hasn't worked since at least 2007, when the multi-tty stuff
4930 was added, and anyway those old terminals are long dead.
4931 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4932 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4934 Fix data-loss with --version (Bug#9574).
4935 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4936 as we can't assume that emacs_strerror is initialized, and strerror
4937 is good enough here.
4938 (main): Invoke atexit earlier, to catch earlier instances of
4939 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4941 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4943 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4944 (keyDown): Remap keypad keys to X11 virtual key codes.
4946 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4948 Fix data-loss with --batch (Bug#9574).
4949 * emacs.c: Include <close-stream.h>.
4950 (close_output_streams): New function.
4951 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4952 and handles errors appropriately.
4953 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4956 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4957 The symptom is a diagnostic "GLib-WARNING **: In call to
4958 g_spawn_sync(), exit status of a child process was requested but
4959 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4960 waitpid(), so exit status can't be returned." The diagnostic
4961 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4962 The real bug is a race condition between Emacs and glib: Emacs
4963 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4964 so that glib can't find it. Work around the bug by invoking
4965 waitpid only on subprocesses that Emacs itself creates.
4966 * process.c (create_process, record_child_status_change):
4967 Don't use special value -1 in pid field, as the caller now must
4968 know the pid rather than having the callee infer it.
4969 The inference was sometimes incorrect anyway, due to another race.
4970 (create_process): Set new 'alive' member if child is created.
4971 (process_status_retrieved): New function.
4972 (record_child_status_change): Use it.
4973 Accept negative 1st argument, which means to wait for the
4974 processes that Emacs already knows about. Move special-case code
4975 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4976 processes that have already been waited for, by testing and
4977 clearing new 'alive' member.
4978 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4979 now does this internally.
4980 (handle_child_signal): Let record_child_status_change do all
4981 the work, since we do not want to reap all exited child processes,
4982 only the child processes that Emacs itself created.
4983 * process.h (Lisp_Process): New boolean member 'alive'.
4985 Omit duplicate definitions no longer needed with gcc -g3.
4986 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4987 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4988 Define only as macros. There's no longer any need to also define
4989 these symbols as enums or as constants, since we now assume
4990 gcc -g3 when debugging.
4992 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4994 * lisp.mk: Adjust comments to the fact that term/internal is now
4995 loaded from loadup.el.
4997 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4998 (msdos_fatal_signal): New function.
4999 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5002 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5003 for GCC versions before 4.
5004 (emacs_raise): Define to call msdos_fatal_signal.
5006 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5007 iterator when starting in the middle of a display or overlay
5010 2012-11-03 Chong Yidong <cyd@gnu.org>
5012 * process.c (wait_reading_process_output): Clean up the last
5015 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5017 * process.c (wait_reading_process_output): Avoid a race condition
5018 with SIGIO delivery (Bug#11536).
5020 2012-11-03 Chong Yidong <cyd@gnu.org>
5022 * buffer.c (cursor_type): Untabify docstring.
5024 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5026 * frame.h (struct frame): Drop can_have_scroll_bars member
5027 which is meaningless for a long time. Adjust comments.
5028 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5029 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5031 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5033 * window.c (decode_next_window_args): Update window arg after
5034 calling decode_live_window and so fix crash reported at
5035 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5036 by Juanma Barranquero <lekktu@gmail.com>.
5037 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5038 * font.c (Ffont_at): Likewise.
5040 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5042 * widget.c (resize_cb): New function.
5043 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5044 (EmacsFrameResize): Check if all is up to date before changing frame
5047 2012-11-02 Eli Zaretskii <eliz@gnu.org>
5049 Implement backtrace output for fatal errors on MS-Windows.
5050 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
5051 (BACKTRACE_LIMIT_MAX): New macro.
5052 (w32_backtrace): New function.
5053 (emacs_abort): Use w32_backtrace when the user chooses not to
5054 attach a debugger. Update the text of the abort dialog.
5056 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5058 Window-related stuff cleanup here and there.
5059 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5060 Use decode_any_window.

5068 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5069 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5072 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5074 Remove pad from struct input_event.
5075 * termhooks.h (struct input_event): Remove padding field.
5077 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5078 member is never cons for a long time. Adjust comment.
5079 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5080 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5081 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5082 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5084 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5086 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5088 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5090 Fix crash when using Emacs as commit editor for git (Bug#12697).
5091 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5092 and it is configured in conf_post.h.
5093 (Fcall_process): Don't invoke both setsid and setpgid; the former
5094 is enough, if it exists.
5095 * callproc.c (Fcall_process, child_setup):
5096 * process.c (create_process): Use setpgid.
5097 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5099 * dispnew.c (init_display): Initialize the foreground group
5100 if we are running a tty display.
5101 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5102 * lisp.h (init_foreground_group): New decl.
5103 * sysdep.c (inherited_pgroup): New static var.
5104 (init_foreground_group, tcsetpgrp_without_stopping)
5105 (narrow_foreground_group, widen_foreground_group): New functions.
5106 (init_sys_modes): Narrow foreground group.
5107 (reset_sys_modes): Widen foreground group.
5109 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5111 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5113 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5115 * minibuf.c (read_minibuf): Restore current buffer since
5116 choose_minibuf_frame calling Fset_frame_selected_window may
5117 change it (Bug#12766).
5119 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5121 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5123 2012-10-30 Kenichi Handa <handa@gnu.org>
5125 * font.c (Ffont_at): If WINDOW is specified and it is not
5126 displaying the current buffer, signal an error.
5128 2012-10-29 Daniel Colascione <dancol@dancol.org>
5130 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5131 In preparation for fixing bug#12739, move these functions from
5134 * coding.h, coding.c: ... to here, and compile them only when
5135 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5136 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5138 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5140 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5141 (timer_loop, getitimer, setitimer): Use it instead of
5142 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5144 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5147 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5149 * nsterm.m (NO_APPDEFINED_DATA): New define.
5150 (last_appdefined_event_data): New variable
5151 (last_appdefined_event): Remove.
5152 (ns_select): Initialize t from last_appdefined_event_data instead
5153 of [last_appdefined_event data1].
5154 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5155 remove last_appdefined_event (Bug#12698).
5157 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5159 * frame.c (x_set_font): Catch internal error.
5161 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5163 Avoid overflow in w32 implementation of interval timers.
5164 When possible, for ITIMER_PROF count only times the main thread
5166 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5167 'volatile ULONGLONG' types. All the other data which was
5168 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5169 (GetThreadTimes_Proc): New typedef.
5170 (w32_get_timer_time): New function, returns a suitable time value
5172 (timer_loop): Enter critical section when accessing ULONGLONG
5173 values of the itimer_data struct, as these accesses are no longer
5174 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5175 Remove unused variable.
5176 (init_timers): Initialize s_pfn_Get_Thread_Times.
5177 (start_timer_thread): Don't assign itimer->caller_thread here.
5178 (getitimer): Assign itimer->caller_thread here.
5179 (setitimer): Always call getitimer to get the value of ticks_now.
5180 (sys_spawnve): Avoid compiler warning about format mismatch.
5182 2012-10-26 Eli Zaretskii <eliz@gnu.org>
5184 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5185 mouse movement events if the menu bar is active. This avoids
5186 producing a busy "hour-glass" cursor by Windows if the mouse
5187 pointer is positioned over a tooltip shown for some menu item.
5189 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5191 Don't assume process IDs fit in int.
5192 * emacs.c (shut_down_emacs) [!DOS_NT]:
5193 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5194 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5195 Use pid_t, not int, to store process IDs, as 'int'
5196 is not wide enough on a few platforms (e.g., AIX and IRIX).
5198 2012-10-23 Kenichi Handa <handa@gnu.org>
5200 The following change is to make face-font-rescale-alist work
5201 correctly for non-ASCII fonts.
5203 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5204 (font_open_for_lface): Handle Vface_font_rescale_alist.
5206 2012-10-23 Chong Yidong <cyd@gnu.org>
5208 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5210 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

5214 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
5216 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
5219 2012-10-21 Glenn Morris <rgm@gnu.org>
5221 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5223 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5225 Port to OpenBSD 5.1.
5226 * frame.c (Fmouse_position, Fmouse_pixel_position):
5227 * xdisp.c (produce_stretch_glyph):
5228 Declare local vars only when they're needed.
5229 This is clearer and avoids a warning on OpenBSD about unused vars.
5230 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5231 This is safer, and avoids OpenBSD warnings about unused vars.
5232 * keyboard.c (record_menu_key): Remove unnecessary decl.
5233 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5234 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5235 as our definition clashes with OpenBSD's.
5236 * xfaces.c (load_face_colors, check_lface_attrs)
5237 (get_lface_attributes_no_remap, get_lface_attributes)
5238 (lface_fully_specified_p, x_supports_face_attributes_p)
5239 (tty_supports_face_attributes_p, face_fontset, realize_face)
5240 (realize_x_face, realize_tty_face):
5241 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5242 merely Lisp_Object *. This is more informative and avoids
5243 a warning on OpenBSD about accessing beyond an object's size.
5245 2012-10-20 Chong Yidong <cyd@gnu.org>
5247 * lread.c (Fload): Doc fix (Bug#12592).
5249 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5251 * font.c (Ffont_at): Fix previous change.
5253 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5255 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5256 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

5269 FD_ISSET (Bug#12668).
5271 2012-10-18 Daniel Colascione <dancol@dancol.org>
5273 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5274 (staticpro): If we run out of staticpro slots, die with an
5275 informative error instead of just calling emacs_abort.
5277 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5279 Fix two flaws reported by Dmitry Antipov.

5534 since unsigned is guaranteed to have that behavior and signed is not.
5535 (read_char): Use ptrdiff_t for string length.
5536 (get_input_pending): Remove first argument, since it was always
5537 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5538 and behave as if it had that value. Return new value of
5539 input_pending. All callers changed.
5540 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5541 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5543 * keymap.c (push_key_description): Omit last arg, which was always 1.

5563 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5564 Don't include termopts.h.
5566 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5568 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5570 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5572 * commands.h (immediate_quit): Remove duplicate decl.
5574 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5576 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5579 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5581 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5583 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5584 match what GetLastError returns. Explain why the function is
5587 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5588 'is_tooltip_frame', to avoid confusion with its global namesake.
5590 2012-10-08 Daniel Colascione <dancol@dancol.org>
5592 * xdisp.c (start_hourglass): Call w32_note_current_window when
5593 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5594 build that caused Emacs to display the hourglass cursor forever.
5596 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5597 which is broken under remote desktop, calculate the number of
5598 colors available for a display based on the display's number of
5599 planes and number of bits per pixel per plane. (bug#10397).
5601 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5603 * nsfont.m (Vfonts_in_cache): New variable.
5604 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5605 are used. Add cached fonts to Vfonts_in_cache.
5606 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5608 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5610 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5612 (FONT_H): Define after FRAME_H.
5613 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5614 Update dependencies.
5616 * w32term.c: Remove leftover declaration of keyboard_codepage.
5618 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5620 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5621 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5622 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5623 (GLOBAL_SOURCES): Add cygw32.c.
5624 ($(BLD)/unexw32.$(O)):
5626 ($(BLD)/w32console.$(O)):
5627 ($(BLD)/w32fns.$(O)):
5628 ($(BLD)/w32heap.$(O)):
5629 ($(BLD)/w32menu.$(O)):
5630 ($(BLD)/w32proc.$(O)): Add w32common.h.
5632 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5634 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5636 2012-10-08 Daniel Colascione <dancol@dancol.org>
5638 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5639 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5640 accidental message numbering hole. Change other messages to
5643 * w32select.h (HAVE_W32SELECT): Remove.
5645 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5646 w32common.h instead of w32heap.h.
5648 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5649 (get_allocation_unit, get_processor_type, get_w32_major_version)
5650 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5651 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5652 (OS_NT, os_subtype, cache_system_info): Move declarations to
5655 * w32heap.c: Include w32common.h.
5656 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5657 (w32_minor_version, w32_build_number, w32_subtype):
5658 Remove duplicate definitions.
5660 * w32fns.c: Include w32common.h; include w32heap.h only in
5663 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5664 Use `report_file_error' instead of `error' in order to better
5665 inform users of what went wrong. Increase NTGUI_UNICODE file
5666 dialog box file name length to 32k, the maximum allowed by the NT
5669 * w32common.h: New file.
5670 (ROUND_UP, ROUND_DOWN, get_page_size)
5671 (get_allocation_unit, get_processor_type, get_w32_major_version)
5672 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5673 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5674 (OS_NT, os_subtype, cache_system_info): Move here.
5676 * unexw32.c, unexcw.c: Include w32common.h.
5678 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5679 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5680 to call syms_of_w32select.
5682 * cygw32.h: Remove obsolete EXFUN declarations.
5684 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5686 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5687 of w32inevt.o from SOME_MACHINE_OBJECTS.
5689 2012-10-08 Daniel Colascione <dancol@dancol.org>
5691 * image.c: Permanent fix for JPEG compilation issue --- limit
5692 jpeglib `boolean' redefinition to Cygwin builds.
5694 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5696 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5698 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5701 2012-10-08 Daniel Colascione <dancol@dancol.org>
5703 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5704 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5705 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5706 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5707 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5708 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5709 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5710 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5711 now a supported configuration.
5713 * Makefile.in: consolidate image variables into LIBIMAGE; add
5714 W32_OBJ and W32_LIBS. Compile new files.
5717 (_DebPrint) declare tracing facility for W32 debugging. We need
5718 to unify tracing later.
5720 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5721 unconditional use of W32 Unicode functions. Cygwin runs only on
5722 100% Unicode operating systems.
5724 * cygw32.c: New file. Define Cygwin-specific facilities.
5725 (Fcygwin_convert_path_to_windows)
5726 (Fcygwin_convert_path_from_windows): New user functions for
5727 accessing Cygwin path-munging routines.
5729 * cygw32.h: New file.
5730 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5731 UTF-16LE strings temporarily inside non-Lisp-visible string
5734 (w32_strerror): Just what it says on the tin.
5736 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5737 also run for Cygwin; both systems have the same problem with using
5738 GUI facilities in a forked child. Also call syms_of_cygw32,
5739 syms_of_w32select in correct places.
5741 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5742 needs fork-then-exec for daemon launching.
5744 * font.h: Include frame.h.
5746 * image.c: Use the image library cache machinery only when we're
5747 compiling for native WINDOWSNT; Cygwin can use shared libraries
5748 like any other Unixlike system.
5750 * keyboard.c: Clarify a comment regarding the input loop.
5752 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5753 functions directly instead of trying to detect at runtime that our
5754 host operating system supports them. We make this change for two
5755 reasons: Cygwin lacks support for the multibyte character
5756 conversion functions used by the legacy menu code, and Cygwin
5757 never needs to rely on non-Unicode APIs.
5759 * unexw32.c (hinst): Declare extern.
5761 * w32.c: Change header order;
5762 (w32_strerror): Move to w32fns.c because we need it for
5763 non-WINDOWSNT builds.
5765 * w32.h: Add #error macro to make sure we don't include w32.h for
5766 Cygwin builds. Remove w32select declarations.
5768 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5769 w32fns.c. w32console.c is WINDOWSNT-only.
5771 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5772 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5774 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5775 (w32_major_version, w32_minor_version, w32_build_number)
5776 (os_subtype, sound_type): Define here
5777 (w32_defined_color): Make color parameter const for consistency
5778 with other _defined_color functions.
5779 (w32_createwindow): Unconditionally call w32_init_class instead of
5780 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5781 through the code is complex and unnecessary because class
5782 registration is practically free.
5783 (w32_name_of_message): New EMACSDEBUG-only function.
5784 (Fset_message_beep): Move here
5785 (Fx_open_connection): Require that the display name for Windows be
5786 "w32" for consistency, emacsclient disambiguation, and maybe, one
5787 day, multi-window-system support.
5788 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5789 Cygwin files for W32 GUI facilities, since these clearly don't
5790 expect Cygwin names.
5791 (_DebPrint): Define.
5792 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5793 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5794 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5795 (w32_last_error): Remove.
5797 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5799 * w32heap.c (syspage_mask): Declare here.
5800 (cache_system_info): Remove.
5802 * w32inevt.c (faked_key): Define globally, not statically.
5803 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5804 (w32_console_toggle_lock_key): Move to w32fns.c.
5806 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5808 * w32proc.c (_DebPrint): Move to w32fns.c.
5809 * w32select.c: Include string.h, stdio.h for Cygwin.
5810 * w32select.h: New File.
5812 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5814 (w32_message_fd): New variable. Under Cygwin, holds the file
5815 descriptor the system used to tell us about pending thread
5818 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5819 that prevented compilation under non-WINDOWSNT systems.
5821 (w32_initialize): Open /dev/windows and assign it to
5822 w32_message_fd. Provide w32 feature.
5824 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5825 (WM_EMACS_INPUT_READY): add.
5826 (prepend_msg, w32_message_fd): Declare globally.
5829 (keyboard_handle): Use only when WINDOWSNT.
5830 (notify_msg_ready): New function. Posts a message to the main
5831 thread's message queue under CYGWIN, which wakes up the main
5832 thread from select(2) by making the /dev/windows file descriptor
5833 ready. Under WINDOWSNT, it sets an event the same way the old
5836 (post, prepend_msg): Actually call notify_msg_ready instead of
5837 setting the input event directly.
5839 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5841 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5842 but it still has blocs in it, don't return it to the system,
5843 instead of aborting. (Bug#12402)
5845 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5847 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5849 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5850 MAC_OS_X_VERSION_10_6.
5851 (syms_of_nsterm): Remove comment about Panther and above for
5853 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5854 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5855 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5857 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5858 MAC_OS_X_VERSION_10_4.
5860 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5861 MAC_OS_X_VERSION_10_2.
5863 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5865 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5866 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5868 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5869 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5870 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5871 Remove ns_in_resize check.
5872 (ns_clear_frame_area): Remove resize handle code.
5874 * nsfns.m (ns_in_resize): Remove.
5875 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5876 Remove ns_in_resize check.
5878 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5880 Improve sys_siglist detection.
5881 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5882 defined as a macro, as is done in Solaris.
5883 (sys_siglist_entries): New macro.
5884 (save_strsignal): Use it.
5885 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5886 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5888 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5890 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5891 fullscreen/Fullscreen.
5893 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5894 tobar_height is new.
5896 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5897 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5898 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5899 (windowDidResize:): Check for correct window if old style fullscreen.
5900 Capitalize word in comment. Remove incorrect comment.
5901 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5902 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5903 error in drawing background.
5904 (toggleFullScreen:): Remove comment. Rearrange calls.
5905 Set toolbar values to zero, save old height in tobar_height.
5906 Restore tool bar height when leaving fullscreen.
5907 (canBecomeMainWindow): New function.
5909 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5911 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5913 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5915 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5917 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5918 that time stamps of directories could also be changed.
5919 Don't request the too broad GENERIC_WRITE, only the more restrictive
5920 FILE_WRITE_ATTRIBUTES access rights.
5922 * fileio.c (Fset_file_times): Special-case ignoring errors for
5923 directories only on MSDOS, not on MS-Windows.
5925 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5927 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5929 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5931 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5932 see whether CreateFile failed.
5934 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5936 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5937 to avoid similar races.
5938 * keyboard.c (pending_signals): Now bool, not int.
5940 Port timers to OpenBSD, plus check for timer failures.
5941 OpenBSD problem reported by Han Boetes.
5942 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5944 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5945 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5946 like OpenBSD, which has timer_settime but does not declare it.
5947 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5948 whether to use itimerspec-related primitives. All uses of
5949 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5951 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5953 * profiler.c (handle_profiler_signal): Fix a malloc race
5954 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5956 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5958 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5960 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5962 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5963 consistent with the change in return value of 'safe_strsignal'.
5965 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5967 Prefer plain 'static' to 'static inline' (Bug#12541).
5968 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5969 (bidi_set_sor_type, bidi_push_embedding_level)
5970 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5971 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5972 (bidi_cache_search, bidi_cache_ensure_space)
5973 (bidi_cache_iterator_state, bidi_cache_find)
5974 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5975 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5976 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5977 Now 'static', not 'static inline'.
5979 Count overruns when profiling; change units to ns.
5980 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5981 Give extra weight to samples after overruns, to attempt to count
5982 the time more accurately.
5983 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5984 the underlying primitives nominally do ns.
5985 (Fprofiler_cpu_start): Document the change. Mention that
5986 the sampling intervals are only approximate.
5988 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5990 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5992 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5993 case for the special 0 coding-system.
5995 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5996 (Fmake_overlay): Remove redundant tests.
5997 (fix_start_end_in_overlays): Remove redundant recentering.
5999 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6001 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6002 Update dependencies.
6004 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6006 Fix a malloc race condition involving strsignal.
6007 A signal can arrive in the middle of a malloc, and Emacs's signal
6008 handler can invoke strsignal, which can invoke malloc, which is
6009 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6010 Fix it by altering the signal handler so that it does not invoke
6012 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6013 * process.c (status_message): Use const pointer, in case strsignal
6014 is #defined to safe_strsignal.
6015 * sysdep.c (sys_siglist, init_signals): Always define and
6016 initialize a substitute sys_siglist if the system does not define
6017 one, even if HAVE_STRSIGNAL.
6018 (safe_strsignal): Rename from strsignal. Always define,
6019 using sys_siglist. Return a const pointer.
6020 * syssignal.h (safe_strsignal): New decl.
6021 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6023 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6025 * w32proc.c (timer_loop): Fix code that waits for timer
6026 expiration, to avoid high CPU usage.
6028 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6030 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6031 (sweep_weak_table): Remove redundant prototypes.
6033 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6035 * emacs.c: Move the inclusion of TERM_HEADER after including
6036 windows.h on WINDOWSNT. This avoids compilation problems with
6039 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6041 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6042 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6043 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6044 as the previous version used 'void *'.
6046 * ralloc.c (ROUNDUP): Fix last change.
6047 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6050 * w32proc.c <disable_itimers>: New static flag.
6051 (init_timers): Initialize it to zero, after creating the critical
6052 sections used by the timer threads.
6053 (term_timers): Set to 1 before deleting the critical sections.
6054 (getitimer, setitimer): If disable_itimers is non-zero, return an
6055 error indication without doing anything. Reported by Fabrice
6056 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6057 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6059 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6062 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6063 term_ntproc after all the other bookkeeping, to get timers working
6064 as long as possible.
6066 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6068 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6069 Suggested by Juri Linkov in
6070 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6072 Prefer plain 'static' to 'static inline' (Bug#12541).
6073 With static functions, modern compilers inline pretty well by
6074 themselves; advice from programmers often hurts as much as it helps.
6075 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6076 this change shrinks the text size of the Emacs executable by 1.1%
6077 without affecting CPU significantly in my benchmark.

6158 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6160 Revert the FOLLOW-SYMLINKS change for file-attributes.
6161 Doing it right would require several changes to Tramp, and there's
6162 not enough time to get that tested before the freeze today.
6163 * dired.c (directory_files_internal, Ffile_attributes):
6166 * frame.c (x_report_frame_params): Port better to wider ints.
6167 Do not assume that EMACS_UINT is the same width as uprintmax_t,

6200 * w32.c (init_environment, get_emacs_configuration): Support AMD64
6202 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
6203 compatibility with x64.
6205 * vm-limit.c (lim_data): Now size_t.
6206 (check_memory_limits): Adjust prototypes of real_morecore and
6207 __morecore to receive argument of type ptrdiff_t. Use size_t for

6360 Profiler improvements: more-accurate timers, overflow checks.
6361 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6362 signal.h, setjmp.h. Include systime.h instead.
6363 (saturated_add): New function.

6370 All uses changed to store the new value.
6371 (handle_profiler_signal): Rename from sigprof_handler_1,
6372 for consistency with other handlers. Do not check whether
6373 cpu_log is a hash-table if garbage collecting, since it
6374 doesn't matter in that case.

6376 for consistency with other handlers.
6377 (setup_cpu_timer): New function, with much of what used to be in
6378 Fprofiler_cpu_start. Check for out-of-range argument.
6379 Prefer timer_settime if available, and prefer
6380 thread cputime clocks, then process cputime clocks, then
6381 monotonic clocks, to the old realtime clock. Use make_timeval
6382 to round more-correctly when falling back to setitimer.
6383 (Fprofiler_cpu_start): Use it.
6384 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6385 Don't assume that passing NULL as the 2nd argument of setitimer
6386 is the same as passing a pointer to all-zero storage.
6387 Ignore SIGPROF afterwards.
6388 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6389 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6390 non-fatal signal handlers. Ignore SIGPROF on startup.
6391 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6392 in profiler.c, since sysdep.c now uses it.
6394 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

6448 * character.h (MAYBE_UNIFY_CHAR): Remove.
6449 * charset.c, charset.h (maybe_unify_char): Now static.
6450 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6451 Since this stuff is now private to charset.c, there's no need for
6452 a public macro and no need to inline by hand.

6483 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6485 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6487 Prefer POSIX timers if available.
6488 They avoid a race if the timer is too close to the current time.
6489 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6490 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6491 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6493 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6495 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
6496 CHAR_STRING_ADVANCE.
6497 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
6498 STRING_CHAR_ADVANCE.
6500 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6502 Move Vlibrary_cache to emacs.c and reset before dumping.
6504 * lisp.h (reset_image_types): Declare.
6505 [WINDOWSNT] (Vlibrary_cache): Declare.
6507 * image.c (reset_image_types): New function.
6509 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

6516 * w32.h (Vlibrary_cache): Do not declare.
6518 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6520 * w32proc.c (sys_signal): Handle all signals defined by the
6521 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6522 handlers for signals supported by Windows. Don't override
6523 term_ntproc as the handler for SIGABRT.
6524 (sigaction): Rewrite to call sys_signal instead of duplicating its
6526 (sys_kill): Improve commentary.
6528 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6529 consistency with a signature of a signal handler. All callers
6531 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6532 install term_ntproc as a signal handler for SIGABRT, as that
6533 should be done by the dumped Emacs.
6535 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6537 * w32select.c (term_w32select): Protect against repeated
6538 invocation by setting clipboard_owner to NULL after calling

6542 and term_ntproc to their modified signatures.
6544 * character.c (char_string, string_char): Remove calls to
6545 MAYBE_UNIFY_CHAR. See the discussion starting at
6546 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6549 2012-09-25 Chong Yidong <cyd@gnu.org>
6551 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6553 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6555 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6556 when encountering an unknown bytecode.
6558 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6560 image.c, indent.c: Use bool for booleans.
6561 * dispextern.h (struct image_type): Members valid_p, load, init
6562 now return bool, not int. All uses changed.
6563 * image.c: Omit unnecessary static decls.
6564 (x_create_bitmap_mask, x_build_heuristic_mask):
6565 Return void, not int, since callers don't care about the return value.

6594 Use bool for booleans.
6596 2012-09-24 Chong Yidong <cyd@gnu.org>
6598 * chartab.c (Fset_char_table_default): Obsolete function removed.
6600 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6602 Move pid_t related decls out of lisp.h.
6603 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6604 (interruptible_wait_for_termination):
6605 Move these decls from lisp.h to syswait.h, since they use pid_t.
6606 Needed on FreeBSD; see Herbert J. Skuhra in
6607 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6608 * callproc.c: Include syswait.h.

6625 * nsmenu.m (ns_update_menubar):
6626 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6627 * xfns.c (Fx_show_tip) [USE_GTK]:
6628 Use bool for boolean.
6629 * gtkutil.c (xg_update_frame_menubar):
6630 * xmenu.c (update_frame_menubar):
6631 Return void, not int, since caller ignores return value.
6632 * gtkutil.c (xg_change_toolbar_position):
6635 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6637 * makefile.w32-in (BLOCKINPUT_H): Remove.

6654 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6656 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6657 fatal_error_backtrace.
6659 * w32proc.c (sys_kill): Undo last change: don't do anything when
6660 invoked to deliver SIGABRT to our own process. This is now
6661 handled by emacs_raise.
6663 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6665 * w32term.c (w32_read_socket): Remove leftover reference to
6666 interrupt_input_pending.
6668 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6670 Do not use SA_NODEFER.
6671 Problem reported by Dani Moncayo in
6672 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6674 * sysdep.c (emacs_abort): Do not reset signal handler.
6675 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6676 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6677 wanted even on POSIXish hosts, and it doesn't work on Windows.
6679 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6681 * xterm.c (x_term_init): Call fixup_locale before and after calling
6682 gtk_init (Bug#12392).
6684 2012-09-23 Chong Yidong <cyd@gnu.org>
6686 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6687 Vdynamic_library_alist.
6689 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6690 (Fgnutls_available_p): Caller changed.
6692 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6693 (Flibxml_parse_xml_region): Likewise.
6695 * dispextern.h (struct image_type): Remove arg from init function.
6697 * image.c (Finit_image_library, lookup_image_type)
6698 (define_image_type): Remove now-unneeded second arg.
6699 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6700 (init_tiff_functions, init_gif_functions, init_svg_functions):
6701 Arglist and w32_delayed_load calling convention changed.
6702 (gs_type): Remove init_gs_functions; there is no such function.
6703 (valid_image_p, make_image): Fix caller to lookup_image_type.
6705 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6707 Simplify and avoid signal-handling races (Bug#12471).
6709 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6710 Avoid recursive loop if there's a fatal error in the function itself.
6711 * atimer.c (pending_atimers):
6712 * blockinput.h: Don't include "atimer.h"; no longer needed.
6713 (interrupt_input_pending): Remove. All uses removed.
6714 pending_signals now counts both atimers and ordinary interrupts.
6715 This is less racy than having three separate pending-signal flags.
6716 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6718 Rename from their upper-case counterparts BLOCK_INPUT,
6719 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6720 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6721 This makes it easier to access volatile variables more accurately.
6722 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6723 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6724 that's more reliable if the code is buggy and sets
6725 interrupt_input_blocked to a negative value. All uses changed.
6726 * atimer.c (deliver_alarm_signal):
6727 Remove. No need to deliver this to the parent; any thread can
6728 handle this signal now. All uses replaced by underlying handler.
6729 * atimer.c (turn_on_atimers):
6730 * dispnew.c (handle_window_change_signal):
6731 * emacs.c (handle_danger_signal):
6732 * keyboard.c (kbd_buffer_get_event):
6733 Don't reestablish signal handler; not needed with sigaction.
6734 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6736 Rework to avoid unnecessary accesses to volatile variables.
6737 (UNBLOCK_INPUT_TO): Now a function.
6738 (totally_unblock_input, unblock_input): New decls.
6739 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6740 (init_data): Remove. Necessary stuff now done in init_signal.
6741 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6742 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6743 (fatal_error_code): Remove; no longer needed.
6744 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6745 it doesn't always backtrace. All uses changed. No need to reset
6746 signal to default, since sigaction and/or die does that for us now.
6747 Use emacs_raise (FOO), not kill (getpid (), FOO).
6748 (main): Check more-accurately whether we're dumping.
6749 Move fatal-error setup to sysdep.c
6750 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6751 * gtkutil.c (xg_get_file_name, xg_get_font):
6752 Remove no-longer-needed signal-mask manipulation.
6753 * keyboard.c, process.c (POLL_FOR_INPUT):
6754 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6755 * keyboard.c (read_avail_input): Remove.
6756 All uses replaced by gobble_input.
6757 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6758 (kbd_buffer_store_event_hold, gobble_input):
6759 (record_asynch_buffer_change) [USABLE_SIGIO]:
6760 (store_user_signal_events):
6761 No need to mess with signal mask.
6762 (gobble_input): If blocking input and there are terminals, simply
6763 set pending_signals to 1 and return. All hooks changed to not
6764 worry about whether input is blocked.
6765 (process_pending_signals): Clear pending_signals before processing
6766 them, in case a signal comes in while we're processing.
6767 By convention callers now test pending_signals before calling us.
6768 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6769 New functions, to support changes to blockinput.h.
6770 (handle_input_available_signal): Now extern.
6771 (reinvoke_input_signal): Remove. All uses replaced by
6773 (quit_count): Now volatile, since a signal handler uses it.
6774 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6775 All callers changed. Block SIGINT only if not already blocked.
6776 Clear sigmask reliably, even if Fsignal returns, which it can.
6777 Omit unnecessary accesses to volatile var.
6778 (quit_throw_to_read_char): No need to restore sigmask.
6779 * keyboard.c (gobble_input, handle_user_signal):
6780 * process.c (wait_reading_process_output):
6781 Call signal-handling code rather than killing ourselves.
6782 * lisp.h: Include <float.h>, for...
6783 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6784 (pending_signals): Now volatile.
6785 (syms_of_data): Now const if IEEE floating point.
6786 (handle_input_available_signal) [USABLE_SIGIO]:
6787 (terminate_due_to_signal, record_child_status_change): New decls.
6788 * process.c (create_process): Avoid disaster if memory is exhausted
6789 while we're processing a vfork, by tightening the critical section
6791 (send_process_frame, process_sent_to, handle_pipe_signal)
6792 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6794 (send_process): No need for setjmp/longjmp any more, since the
6795 SIGPIPE stuff is now gone. Instead, report an error if errno
6797 (record_child_status_change): Now extern. PID and W are now args.
6798 Return void, not bool. All callers changed.
6799 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6800 Remove. All uses removed. This bug should be fixed now in a
6802 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6803 and record the child status change directly. This avoids the
6804 need to futz with the signal mask.
6805 (process_fatal_action): Move here from emacs.c.
6806 (emacs_sigaction_flags): New function, containing
6807 much of what used to be in emacs_sigaction_init.
6808 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6809 caught by emacs, to make races less likely.
6810 (deliver_process_signal): Rename from handle_on_main_thread.
6812 (BACKTRACE_LIMIT_MAX): Now at top level.
6813 (thread_backtrace_buffer, threadback_backtrace_pointers):
6815 (deliver_thread_signal, deliver_fatal_thread_signal):
6816 New functions, for more-accurate delivery of thread-specific signals.
6817 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6818 (deliver_arith_signal): Handle in this thread, not
6819 in the main thread, since it's triggered by this thread.
6820 (maybe_fatal_sig): New function.
6821 (init_signals): New arg DUMPING so that we can be more accurate
6822 about whether we're dumping. Caller changed.
6823 Treat thread-specific signals differently from process-general signals.
6824 Block all signals while handling fatal error; that's safer.
6825 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6827 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6828 Ignore SIGPIPE unless batch.
6829 (emacs_backtrace): Output backtrace for the appropriate thread,
6830 which is not necessarily the main thread.
6831 * syssignal.h: Include <stdbool.h>.
6832 (emacs_raise): New macro.
6833 * xterm.c (x_connection_signal): Remove; no longer needed
6834 now that we use sigaction.
6835 (x_connection_closed): No need to mess with sigmask now.
6836 (x_initialize): No need to reset SIGPIPE handler here, since
6837 init_signals does this for us now.
6839 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6841 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6842 background rect may be larger (Bug#12245).
6844 2012-09-23 Chong Yidong <cyd@gnu.org>
6846 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6848 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6850 * .gdbinit: Just stop at fatal_error_backtrace.
6851 See Stefan Monnier's request in
6852 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6853 Remove no-longer-used query of system type.
6855 2012-09-22 Chong Yidong <cyd@gnu.org>
6857 * search.c (Freplace_match): Doc fix (Bug#12325).
6859 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6861 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6862 (Fline_end_position): Doc fix.
6864 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6866 2012-09-22 Chong Yidong <cyd@gnu.org>
6868 * dispextern.h (struct image_type): Add new slot, storing a type
6869 initialization function.
6871 * image.c (define_image_type): Call the image initializer function
6872 if it is defined. Arguments and return value changed.
6873 (valid_image_p, make_image): Callers changed.
6874 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6875 (gif_type, imagemagick_type, svg_type, gs_type):
6876 Add initialization functions.
6877 (Finit_image_library): Call lookup_image_type.
6878 (CHECK_LIB_AVAILABLE): Macro deleted.
6879 (lookup_image_type): Call define_image_type here, rather than via
6880 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6881 (syms_of_image): Move define_image_type calls for xbm_type and
6882 pbm_type to lookup_image_type.
6884 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6886 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6887 'idle_timers' from here ...
6888 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6889 lists, to avoid infloops when the timer does something stupid,
6890 like reinvoke itself with the same or smaller time-out.
6893 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6895 * window.c (Fsplit_window_internal): Handle only Qt value of
6896 Vwindow_combination_limit separately.
6897 (Qtemp_buffer_resize): New symbol.
6898 (Vwindow_combination_limit): New default value.
6901 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6903 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6904 the new overlay string. (Bug#10159)
6906 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6908 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6909 or that fprintf is async-signal-safe. POSIX doesn't require
6912 2012-09-22 Chong Yidong <cyd@gnu.org>
6914 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6917 2012-09-22 Kenichi Handa <handa@gnu.org>
6919 * composite.c (composition_reseat_it): Handle the case that a
6920 grapheme cluster is not covered by a single font (Bug#12352).
6922 2012-09-21 Chong Yidong <cyd@gnu.org>
6924 * image.c (define_image_type): Avoid adding duplicate types to
6925 image_types (Bug#12463). Suggested by Jörg Walter.
6927 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6929 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6930 (print_load_command_name): Add case LC_DATA_IN_CODE.
6931 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6933 2012-09-21 Glenn Morris <rgm@gnu.org>
6935 * eval.c (Frun_hook_with_args_until_success)
6936 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6938 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6940 * fileio.c (Ffile_selinux_context): Only call freecon when
6941 lgetfilecon succeeded.
6942 (Fset_file_selinux_context): Likewise. (Bug#12444)
6944 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6946 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6947 reordering, locate the cursor by calling set_cursor_from_row; if
6948 that fails, clear the desired glyph matrix before returning a
6949 failure indication to the caller. Fixes leaving garbled display
6950 when fast scrolling with a down-key. (Bug#12403)
6951 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6952 scrolling through multibyte text.
6954 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6956 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6957 calling mark_vectorlike since that's the one that marks the window.
6958 (mark_discard_killed_buffers): Mark the final cdr.
6959 * window.h (struct window): Move prev/next_buffers to the
6960 non-standard fields.
6961 * window.c (make_window): Initialize prev/next_buffers manually.
6963 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6965 Omit unused arg EXPECTED from socket hooks.
6966 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6967 * nsterm.m (ns_term_init):
6968 * termhooks.h (struct terminal.read_socket_hook):
6969 * w32inevt.c (w32_console_read_socket):
6970 * w32term.c (w32_read_socket):
6971 * xterm.c (XTread_socket):
6972 Omit unused arg EXPECTED. All callers changed.
6973 (store_user_signal_events): Return void, not int, since callers no
6974 longer care about the return value. All uses changed.
6976 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6978 * w32gui.h (XParseGeometry): Do not declare.
6980 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6982 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6983 Ignore 'expected'. See Eli Zaretskii in
6984 <http://bugs.gnu.org/12471#8> (last line).
6986 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6987 (XParseGeometry): Now static. Substitute extremal values for
6988 values that are out of range.
6990 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6992 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6994 * nsfns.m (XParseGeometry): Remove.
6995 (Fx_create_frame): Call x_set_offset to correctly interpret
6996 top_pos in geometry.
6998 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6999 (Fx_parse_geometry): If there is a space in string, call
7000 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7002 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7004 * search.c (scan_buffer): Use character positions in calls to
7005 region_cache_forward and region_cache_backward, not byte
7006 positions. (Bug#12196)
7008 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7009 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7011 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7012 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7013 emacs_blocked_malloc, now deleted.
7015 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7017 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7018 The workaround was for improving performance on Solaris 2.4, but
7019 is getting in the way now. Emacs will still work if someone is
7020 still running Solaris 2.4 in a museum somewhere; Sun dropped
7021 support for Solaris 2.4 in 2003.
7022 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7023 * process.c (create_process) [HAVE_WORKING_VFORK]:
7024 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7025 since Emacs no longer uses vfork on that platform.
7027 2012-09-17 Glenn Morris <rgm@gnu.org>
7029 * emacs.c: Use COPYRIGHT.
7031 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7033 Remove configure's --without-sync-input option (Bug#12450).
7034 When auditing signal-handling in preparation for cleaning it up,
7035 I found that SYNC_INPUT has race conditions and would be a real
7036 pain to fix. Since it's an undocumented and deprecated
7037 configure-time option, now seems like a good time to remove it.
7038 Also see <http://bugs.gnu.org/11080#16>.
7039 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7040 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7041 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7042 (malloc_hysteresis):
7043 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7044 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7045 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7046 (dont_register_blocks, bytes_used_when_reconsidered)
7047 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7048 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7049 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7050 Remove. All uses removed.
7051 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7052 implementation, one that depends on whether the new macro
7053 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7055 * atimer.c (run_timers, handle_alarm_signal):
7056 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7057 (handle_async_input, process_pending_signals)
7058 (handle_input_available_signal, init_keyboard):
7059 * nsterm.m (ns_read_socket):
7060 * process.c (wait_reading_process_output):
7061 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7062 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7064 * xterm.c (XTread_socket):
7066 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7067 * eval.c (handling_signal): Remove. All uses removed.
7068 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7069 All uses replaced with the SYNC_INPUT version.
7070 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7072 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7075 * font.c (Ffont_shape_gstring): Remove unused local.
7077 2012-09-16 Glenn Morris <rgm@gnu.org>
7079 * Makefile.in (clean): No longer run nextstep's clean.
7081 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7083 (ns-app): Move here from ns.mk, and simplify.
7084 (clean): Simplify nextstep entry.
7085 * ns.mk: Remove file.
7087 2012-09-17 Kenichi Handa <handa@gnu.org>
7089 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7090 not covert the last few charactes.
7092 2012-09-16 Kenichi Handa <handa@gnu.org>
7094 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7095 here, but just check the validity of glyphs in the glyph-string.
7097 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7099 * window.c (Fwindow_parameter, Fset_window_parameter):
7100 Accept any window as argument (Bug#12452).
7102 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7104 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7105 to ns_term_init to avoid memory leak.
7107 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7108 explicit retain/release.
7109 (ns_term_init): Only allow one display. Initialize outerpool and
7112 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7114 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7115 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7116 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7117 the Microsoft problem in a different way, by altering ../nt/config.nt.
7119 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7134 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7135 by lisp.h. This completes removal of setjmp.h inclusion
7136 erroneously announced in the previous commit. (Bug#12446)
7138 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7141 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7142 not defined as a macro. The latter happens on MS-Windows.
7145 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7147 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7148 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7149 Some instances of '#include <setjmp.h>' removed, if the
7150 only reason for the instance was because "lisp.h" was included.
7151 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7152 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7153 and _longjmp with the new symbols. Emacs already uses _setjmp if
7154 available, so this change affects only POSIXish hosts that have
7155 sigsetjmp but not _setjmp, such as some versions of Solaris and
7156 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7157 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7158 (png_load_body) [HAVE_PNG]:
7159 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7160 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7161 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7162 since PNG requires jmp_buf. This is the only exception to the
7163 general rule that we now use sys_setjmp and sys_longjmp.
7164 This exception is OK since this code does not change the signal
7165 mask or longjmp out of a signal handler.
7167 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7169 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7170 Include "syssignal.h", for 'main_thread'.
7172 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7174 Avoid out-of-range marker position (Bug#12426).
7175 * insdel.c (replace_range, replace_range_2):
7176 Adjust markers before overlays, as suggested by comments.
7177 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7178 Remove redundant check before calling offset_intervals.
7180 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7182 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7183 current buffer (Bug#12387).
7185 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7187 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7189 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7191 Use a more backwards-compatible timer format (Bug#12430).
7192 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7193 vector element, not from the 4th, since PSECS is now at the end.
7194 (Fcurrent_idle_time): Doc fix.
7196 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7198 Function to mark objects and remove killed buffers at once.
7199 * alloc.c (discard_killed_buffers): Rename to ...
7200 (mark_discard_killed buffers) ... new name. Add marking
7201 of remaining objects. Fix comment. Adjust users.
7202 (mark_object): Do not touch frame buffer lists here.
7203 * frame.c (delete_frame): Reset frame buffer lists here.
7205 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7207 Better workaround for GNOME bug when --enable-gcc-warnings.
7208 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7209 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7210 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7212 Simplify SIGIO usage (Bug#12408).
7213 The code that dealt with SIGIO was crufty and confusing, e.g., it
7214 played tricks like "#undef SIGIO" but these tricks were not used
7215 consistently. Simplify mostly by not #undeffing standard symbols,
7216 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7217 or not as we please) rather than "defined SIGIO" (standard symbol
7218 that we probably shouldn't #undef).
7219 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7220 Modules that need it can include it.
7221 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7222 * dispextern.h (ignore_sigio): New decl.
7223 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7224 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7225 * emacs.c (shut_down_emacs):
7226 * keyboard.c (kbd_buffer_store_event_hold):
7227 Use ignore_sigio rather than invoking 'signal' directly.
7228 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7230 (FIONREAD, SIGIO): Do not #undef.
7231 (tty_read_avail_input): Use #error rather than a syntax error.
7232 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7233 for I_PIPE, used by SETUP_SLAVE_PTY.
7234 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7235 * sysdep.c (croak): Remove; no longer needed. This bit of
7236 temporary code, with Fred N. Fish's comment that it's temporary,
7237 has been in Emacs since at least 1992!
7238 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7239 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7240 * syssignal.h (croak): Remove decl.
7241 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7242 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7243 now that we're termios-only.
7244 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7245 * term.c (dissociate_if_controlling_tty): Use #error rather than
7248 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7249 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7250 to work around GNOME bug 683906.
7251 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7252 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7253 This works around GCC bug 54561.
7255 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7257 More fixes for 'volatile' and setjmp/longjmp.
7258 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7259 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7260 (png_load_body) [HAVE_PNG]:
7261 (jpeg_load_body) [HAVE_JPEG]:
7262 New function, with most of the old parent function's body.
7263 (png_load) [HAVE_PNG]:
7264 (jpeg_load) [HAVE_JPEG]:
7265 Invoke the new function, to avoid longjmp munging our locals.
7266 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7267 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7268 longjmp is passed 2, as the C standard doesn't guarantee this.
7269 Instead, store the failure code into mgr->failure_code.
7271 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7273 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7274 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7275 (syms_of_keyboard): Remove support for unread-command-char.
7277 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7279 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7280 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7281 violation. (Bug#12426)
7283 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7285 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7287 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7289 * eval.c: Add `inhibit-debugger'.
7290 (Qinhibit_debugger): New symbol.
7291 (call_debugger): Bind it instead of Qdebug_on_error.
7292 (maybe_call_debugger): Test Vinhibit_debugger.
7293 (syms_of_eval): Define inhibit-debugger.
7294 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7295 (syms_of_xdisp): Remove inhibit-debug-on-message.
7297 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7299 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7300 If a nonvolatile local variable is written before a _longjmp to
7301 the frame containing the variable, and is read after the _longjmp,
7302 the value read is indeterminate. Some local variables of type
7303 'struct handler' and 'struct catchtag' are used in this way, so
7304 mark each of their slots as volatile if the slot can be set before
7305 _longjmp and read afterwards.
7306 * lisp.h (struct handler): var and chosen_clause are now volatile.
7307 (struct catchtag): val, next, and pdlcount are now volatile.
7309 * bidi.c (bidi_push_it, bidi_pop_it):
7310 * fns.c (copy_hash_table):
7311 * image.c (define_image_type):
7312 * keyboard.c (kbd_buffer_store_event_hold):
7313 * process.c (Fprocess_send_eof):
7314 * xfaces.c (x_create_gc) [HAVE_NS]:
7315 * xgselect.c (xg_select):
7316 Prefer assignment to memcpy when either will do.
7318 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7319 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7320 time an item is removed. No need to mark this function 'inline';
7321 the compiler knows better than we do.
7323 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7325 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7326 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7327 to change_frame_size (Bug#12388).
7328 (windowDidResize:): Pass YES to updateFrameSize.
7330 * nsterm.h: Add delay parameter to updateFrameSize.
7332 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7334 Discard killed buffers from deleted window and frame objects.
7335 This reduces an amount of references to killed buffers and
7336 helps GC to reclaim them faster.
7337 * alloc.c (discard_killed_buffers): New function.
7338 (mark_object): Use it for deleted windows and frames.
7339 (mark_object): If symbol's value is set up for a killed buffer
7340 or deleted frame, restore its global binding.
7341 * data.c (swap_in_global_binding): Add GC notice.
7342 (swap_in_symval_forwarding): Use convenient set_blv_where.
7343 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7344 * window.h: ... to here.
7346 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7348 Convenient macro to check whether the buffer is live.
7349 * buffer.h (BUFFER_LIVE_P): New macro.
7350 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7351 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7353 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7355 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7356 composition cases (Bug#12364).
7358 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7359 overhang of succeeding glyphs overlapping box cursor.
7361 * w32term.c (x_draw_glyph_string): Likewise.
7363 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7365 Simplify, document, and port floating-point (Bug#12381).
7366 The porting part of this patch fixes bugs on non-IEEE platforms
7367 with frexp, ldexp, logb.
7368 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7370 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7371 support, by removing commented-out code and briefly listing the
7372 C89 functions excluded. The commented-out stuff was confusing
7373 maintenance, e.g., we thought we needed cbrt but it was commented out.
7374 (logb): Remove decl; no longer needed.
7375 (isfinite): New macro, if not already supplied.
7376 (isnan): Don't replace any existing macro.
7377 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7378 are present on all C89 platforms.
7379 (Ffrexp): Do not special-case zero, as frexp does the right thing
7381 (Flogb): Do not use logb, as it doesn't have the desired meaning
7382 on hosts that use non-base-2 floating point. Instead, stick with
7383 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7384 frexp, to avoid getting an unspecified result.
7386 * xdisp.c (Qinhibit_debug_on_message): Now static.
7388 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7390 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7391 NSBezierPath (Bug#12131).
7393 2012-09-10 Chong Yidong <cyd@gnu.org>
7395 * fns.c (Fdelq, Fdelete): Doc fix.
7397 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7399 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7400 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7402 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7404 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7405 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7408 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7410 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7411 left fringe if the window has a left margin. This avoids leaving
7412 traces of the cursor because its leftmost pixel is not drawn over.
7414 * dispnew.c (update_window_line): When the left margin area of a
7415 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7416 that screen line. (Bug#12277)
7418 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7420 Assume C89 or later for math functions (Bug#12381).
7421 This simplifies the code, and makes it a bit smaller and faster,
7422 and (most important) makes it easier to clean up signal handling
7423 since we can stop worring about floating-point exceptions in
7424 library code. That was a problem before C89, but the problem
7425 went away many years ago on all practical Emacs targets.
7426 * data.c, image.c, lread.c, print.c:
7427 Don't include <math.h>; no longer needed.
7428 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7429 might be autoconfigured, as that never happens.
7431 * doprnt.c (DBL_MAX_10_EXP):
7432 * print.c (DBL_DIG):
7433 Remove. C89 or later always defines these.
7434 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7435 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7436 (arith_error, domain_error, domain_error2):
7437 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7438 no longer needed -- we simply return what C returns. All uses removed.
7439 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7441 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7442 Remove. All uses expanded, as these macros are no longer used
7443 more than once and are now more trouble than they're worth.
7444 (Ftan): Use tan, not sin / cos.
7445 (Flogb): Assume C89 frexp.
7446 (fmod_float): Assume C89 fmod.
7447 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7448 (init_floatfns): Remove. All uses removed.
7450 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7452 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7453 compositeToPoint for OSX < 10.6 (Bug#12390).
7455 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7457 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7458 This produces more-accurate results.
7460 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7462 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7463 changes (Bug#12088).
7465 2012-09-08 Chong Yidong <cyd@gnu.org>
7467 * syntax.c (Fstring_to_syntax): Doc fix.
7469 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7471 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7472 in the internal border.
7473 (x_set_window_size): Remove static variables and their usage.
7474 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7475 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7476 Remove fringe/internal border adjustment (Bug#11052).
7477 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7478 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7479 (ns_fix_rect_ibw): Remove.
7480 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7481 (ns_dumpglyphs_box_or_relief): Ditto.
7482 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7484 (ns_dumpglyphs_image): Ditto.
7485 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7487 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7488 their usage. Add fringe_extended_p and its use as in other terms.
7489 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7490 scroll bar was removed.
7491 (updateFrameSize): New function.
7492 (windowDidResize): Move code to updateFrameSize and call it.
7494 * nsterm.h (EmacsView): Add updateFrameSize.
7496 2012-09-07 Chong Yidong <cyd@gnu.org>
7498 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7500 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7502 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7504 More signal-handler cleanup (Bug#12327).
7505 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7506 Problem introduced when merging patches. Noted by Eli Zaretskii in
7507 <http://bugs.gnu.org/12327#67>.
7508 * floatfns.c: Comment fix.
7509 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7510 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7511 and anyway the declaration is harmless even if SIGDANGER is not defined.
7512 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7513 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7514 source files not surprisingly expected syssignal.h to define, or
7515 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7516 Include <sys/ioctl.h>, for FIONREAD.
7517 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7518 This eliminates a problem whereby other files mysteriously had
7519 to include "syssignal.h" before including "systty.h" if they
7520 wanted to use "#ifdef SIGIO".
7522 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7524 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7526 * w32.c (sigemptyset): Empty the set.
7527 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7529 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7531 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7533 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7534 (mark_object): Likewise for frame objects.
7536 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7538 * syssignal.h (handle_on_main_thread): Always declare,
7539 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7540 This ports to platforms without HAVE_PTHREAD.
7542 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7544 Signal-handler cleanup (Bug#12327).
7545 Emacs's signal handlers were written in the old 4.2BSD style with
7546 sigblock and sigmask and so forth, and this led to some
7547 inefficiencies and confusion. Rewrite these to use
7548 pthread_sigmask etc. without copying signal sets around. Also,
7549 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7550 'signal', and instead use functions that do not attempt to take
7551 over the system name space. This patch causes Emacs's text
7552 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7553 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7554 Do not include <signal.h> or "syssignal.h", as these
7555 modules do not use signals.
7556 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7557 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7558 Do not include <signal.h>, as "syssignal.h" does that for us now.
7559 * atimer.c (sigmask_atimers): New function.
7560 (block_atimers, unblock_atimers): New functions,
7561 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7563 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7564 no longer needed here.
7565 * emacs.c (main): Inspect existing signal handler with sigaction,
7566 so that there's no need to block and unblock SIGHUP.
7567 * sysdep.c (struct save_signal): New member 'action', replacing
7568 old member 'handler'.
7569 (save_signal_handlers, restore_signal_handlers):
7570 Use sigaction instead of 'signal' to save and restore.
7571 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7572 New function. All users of 'signal' modified to use set_sighandler
7573 if they're writeonly, and to use sys_signal if they're read+write.
7574 (emacs_sigaction_init, forwarded_signal): New functions.
7575 (sys_signal): Remove. All uses replaced by calls to sigaction
7576 and emacs_sigaction_init, or by direct calls to 'signal'.
7577 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7578 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7579 all uses replaced by pthread_sigmask etc. calls.
7580 * syssignal.h: Include <signal.h>.
7581 (emacs_sigaction_init, forwarded_signal): New decls.
7582 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7583 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7584 (sigmask, sys_sigmask): Remove; no longer needed.
7585 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7586 (sigblock, sigunblock, sigfree):
7587 (sigsetmask) [!defined sigsetmask]:
7588 Remove. All uses replaced by pthread_sigmask.
7589 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7590 no longer need to be replaced, and its typical old uses
7591 are now done via emacs_sigaction_init and sigaction.
7592 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7593 (sys_sigdel): Remove; unused.
7594 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7596 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7598 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7599 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7601 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7603 Explicitly mark buffer_defaults and buffer_local_symbols.
7604 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7605 mark_local_symbols here.
7606 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7607 since special buffers aren't marked here any more.
7608 (allocate_buffer): Chain new buffer with all_buffers here...
7609 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7611 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7612 (syms_of_buffer): Remove staticpro of the above.
7613 (init_buffer_once): Set names for buffer_defaults and
7614 buffer_local_symbols.
7616 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7618 Use bool for booleans in font-related modules.
7619 * font.c (font_intern_prop, font_style_to_value)
7620 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7621 (generate_otf_features, font_check_otf_features, font_check_otf)
7622 (font_match_p, font_list_entities, font_at):
7623 * fontset.c (fontset_id_valid_p, reorder_font_vector
7624 (fontset_find_font, Fset_fontset_font)
7625 (face_suitable_for_char_p) [0]:
7626 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7627 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7628 (m17n_flt_initialized, ftfont_shape_by_flt):
7629 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7630 * nsfont.m (nsfont_draw):
7631 * w32font.c (w32font_draw):
7632 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7633 Use bool for booleans.
7634 * font.h: Adjust to above API changes.
7635 (struct font, struct font_driver, struct font_driver_list):
7636 Use bool for booleans.
7637 (struct font): Remove useless member encoding_type.
7639 * fontset.c, xftfont.c: Omit unnecessary static decls.
7641 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7643 * alloc.c (mark_object): Revert window marking code
7644 since it's unsafe for the Fset_window_configuration.
7646 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7648 Fix race conditions with signal handlers and errno (Bug#12327).
7649 Be more systematic about preserving errno whenever a signal
7650 handler returns, even if it's not in the main thread. Do this by
7651 renaming signal handlers to distinguish between signal delivery
7652 and signal handling. All uses changed.
7653 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7654 * data.c (deliver_arith_signal): Rename from arith_error.
7655 * dispnew.c (deliver_window_change_signal): Rename from
7656 window_change_signal.
7657 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7658 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7659 * keyboard.c (deliver_input_available_signal): Rename from
7660 input_available_signal.
7661 (deliver_user_signal): Rename from handle_user_signal.
7662 (deliver_interrupt_signal): Rename from interrupt_signal.
7663 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7664 (deliver_child_signal): Rename from sigchld_handler.
7665 * atimer.c (handle_alarm_signal):
7666 * data.c (handle_arith_signal):
7667 * dispnew.c (handle_window_change_signal):
7668 * emacs.c (handle_fatal_signal, handle_danger_signal):
7669 * keyboard.c (handle_input_available_signal):
7670 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7671 * process.c (handle_pipe_signal, handle_child_signal):
7672 New functions, with the actual signal-handling code taken from the
7673 original respective signal handlers, sans the sporadic attempts to
7674 preserve errno, since that's now done by handle_on_main_thread.
7675 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7676 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7677 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7679 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7680 Move initialization of main_thread to sysdep.c's init_signals.
7681 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7682 our usage, and simplifies the mainline code.
7683 (record_child_status_change): New static function, as a helper
7684 for handle_child_signal, and with most of the old child handler's
7686 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7687 (handle_child_signal): Use the above.
7688 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7689 Moved here from emacs.c.
7690 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7691 code moved here from emacs.c's main function.
7692 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7693 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7694 This lets callers save and restore errno properly.
7696 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7698 Remove redundant or unused things here and there.
7699 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7700 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7701 * editfns.c (Fcompare_buffer_substrings): Likewise.
7702 * frame.h (struct terminal, struct font_driver_list):
7703 Remove redundant declarations.
7704 * window.h (Qleft, Qright): Likewise.
7706 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7708 Do not mark objects from deleted buffers, windows and frames.
7709 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7710 (mark_object): Likewise for windows and frames.
7712 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7714 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7715 buffer_defaults and buffer_local_symbols as valid objects.
7716 Return special value to denote them.
7718 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7720 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7721 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7722 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7723 (file_name_absolute_p, Fsubstitute_in_file_name):
7724 (check_executable, check_writable, Ffile_accessible_directory_p)

7726 (Finsert_file_contents, choose_write_coding_system)
7727 (Fwrite_region, build_annotations, a_write, e_write)
7729 * filelock.c (boot_time_initialized, get_boot_time)
7730 (get_boot_time_1, lock_file_1, within_one_second):
7731 * floatfns.c (in_float):
7732 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7733 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7734 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7735 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7736 * window.c (compare_window_configurations):
7737 Use bool for booleans.
7738 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7739 (Fdefault_file_modes): Now mode_t, not int, for modes.
7740 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7741 (internal_delete_file): Now returns void, not a (boolean) int,
7742 since nobody was looking at the return value.
7743 * lisp.h, window.h: Adjust to above API changes.
7745 * xdisp.c (set_message): Simplify and reindent last change.
7747 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7749 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7751 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7753 * eval.c (call_debugger): Make the function non-static so that we
7754 can call it from set_message.
7756 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7757 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7759 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7761 Give more-useful info on a fatal error (Bug#12328).
7762 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7763 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7764 of doing the work ourselves.
7765 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7766 do most of the work.
7767 (fatal_error_backtrace): New function, taken from the guts
7768 of the old fatal_error_signal, but with a new option to output
7770 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7771 info about the signal than just its number.
7772 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7773 * sysdep.c: Include <execinfo.h>
7774 (emacs_backtrace): New function, taken partly from the previous
7775 code of the 'die' function.
7776 (emacs_abort): Call fatal_error_backtrace rather than abort.
7778 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7780 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7781 eager (load-time) macro-expansion.
7782 * lisp.mk (lisp): Add macroexp.
7784 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7786 Simplify redefinition of 'abort' (Bug#12316).
7787 Do not try to redefine the 'abort' function. Instead, redo
7788 the code so that it calls 'emacs_abort' rather than 'abort'.
7789 This removes the need for the NO_ABORT configure-time macro
7790 and makes it easier to change the abort code to do a backtrace.
7791 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7792 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7793 Remove; sysdep.c's emacs_abort now takes its place.
7794 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7795 'abort' changed to use 'emacs_abort'.
7796 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7797 (abort) [!defined abort]: Rename to ...
7798 (emacs_abort): ... new name.
7799 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7800 the place of the old 'abort' in emacs.c.
7801 * w32.c, w32fns.c (abort): Do not #undef.
7802 * w32.c (emacs_abort): Rename from w32_abort.
7804 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7806 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7807 offsets[j].dv, since the y axis of the screen coordinates points
7808 down, while the y axis of the font definition coordinates points
7809 up. This fixes display of Arabic diacritics such as KASRA and
7810 KASRATAN. (Bug#11860)
7812 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7814 Be more systematic about _setjmp vs setjmp.
7815 * alloc.c (test_setjmp, mark_stack):
7816 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7817 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7818 (png_load, my_error_exit, jpeg_load):
7819 * process.c (send_process_trap, send_process):
7820 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7821 The underscored versions are up to 30x faster on some hosts.
7822 Formerly, the code used setjmp+longjmp sometimes and
7823 _setjmp+_longjmp at other times, with no particular reason to
7824 prefer setjmp+longjmp.
7826 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7828 Fix minor problem found by static checking.
7829 * buffer.c (Fdelete_all_overlays): Return nil.
7831 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7833 * buffer.c (Fdelete_all_overlays): New function.
7835 2012-09-03 Chong Yidong <cyd@gnu.org>

7855 EXCLUDE_SUBRS_P. All callers changed.
7856 * dispextern.h, lisp.h: Reflect above API changes.
7857 * firstfile.c (dummy): Use the address of 'main', whose signature
7858 won't change, instead of the address of 'initialize', whose
7859 signature just changed from int to bool.
7860 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7861 * msdos.c (fatal_error_in_progress): ... from here.
7862 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7864 (redisplay_internal, unwind_redisplay): Simply clear
7865 REDISPLAYING_P when unwinding, instead of saving its previous,
7866 always-false value and then restoring it.
7868 Clean up some extern decls.
7869 Mostly, this hoists extern decls out of .c files and into .h files.
7870 That way, we're more likely to catch errors if the interfaces change.
7871 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7872 declare xg_mark_data.
7873 * dispextern.h (x_frame_parm_handlers):

7891 * xfont.c (x_clear_errors):
7892 * xterm.c (x_frame_parm_handlers):
7893 Remove now-redundant extern decls.
7894 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7895 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7897 * xfaces.c: Remove unnecessary static decls.
7898 * xterm.c (updating_frame): Remove decl of nonexistent object.
7900 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7901 when building globals.h, as the objects that are not built on
7902 this host are not needed to compile C files on this host.
7904 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7906 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7954 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7956 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7957 more than one grapheme cluster passed to the shaper: compute the
7958 offset adjustment values separately for each cluster. (Bug#11860)
7960 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7961 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7962 about implicit conversions from integer to pointer.
7964 2012-09-01 Daniel Colascione <dancol@dancol.org>
7966 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7967 system used too early.
7969 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7971 Better seed support for (random).

8020 window system declarations.
8022 * frame.h: Move common functions here: set_frame_menubar,
8023 x_set_window_size, x_sync, x_get_focus_frame,
8024 x_set_mouse_position, x_set_mouse_pixel_position,
8025 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8052 * lisp.h (mark_ttys): Remove prototype.
8053 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8054 to mark_ttys because all possible values of 'top_frame' slot are
8055 the frames which are reachable from Vframe_list.
8056 * term.c (mark_ttys): Remove.
8057 (init_tty): Safely initialize 'top_frame' slot with Qnil.

8086 * lread.c (init_lread): For out-of-tree builds, only add the
8087 source directory's site-lisp dir to the load-path if it exists,
8088 consistent with in-tree builds. (Bug#12302)
8090 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

8109 Handle click on close button as quit.
8111 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8112 Add window_closed and button_values. Add void as return value for
8113 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8114 Add process_dialog as new member.
8116 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8118 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

8224 Omit int (actually boolean) argument. It wasn't being used.
8226 * composite.h, lisp.h: Reflect above API changes.
8228 * cmds.c, coding.c: Use bool for booleans.
8229 * cmds.c (move_point, Fself_insert_command):
8230 * coding.h (struct composition status, struct coding_system):
8231 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
8232 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
8233 (emacs_mule_char, decode_coding_emacs_mule)

8246 (detect_coding_system, char_encodable_p)
8247 (Funencodable_char_position, code_convert_region)
8248 (code_convert_string, code_convert_string_norecord)
8249 (Fset_coding_system_priority):
8250 * fileio.c (Finsert_file_contents):
8251 Use bool for booleans.
8252 * coding.h, lisp.h: Reflect above API changes.
8253 * coding.c: Remove unnecessary static function decls.
8254 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8255 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8256 not a boolean 'int', since callers never look at the return value.
8257 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8258 * coding.h (decoding_buffer_size, encoding_buffer_size)
8259 (emacs_mule_string_char): Remove unused extern decls.
8260 (struct iso_2022_spec, struct coding_system):
8261 Use 'unsigned int : 1' for boolean fields, since there's more than one.
8262 (struct emacs_mule_spec): Remove unused field 'full_support'.
8263 All initializations removed.
8264 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8266 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8268 Fix spare memory change (Bug#12286).
8269 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8270 (valid_lisp_object_p): Likewise.
8272 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8274 * window.c (Fset_window_configuration): Record any window's old
8275 buffer if it's replaced (see Bug#8789). If the new current
8276 buffer doesn't appear in the selected window, go to its old
8279 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8281 Special MEM_TYPE_SPARE to denote reserved memory.
8282 * alloc.c (enum mem_type): New memory type.
8283 (refill_memory_reserve): Use new type for spare memory.
8284 This prevents live_cons_p and live_string_p from incorrect
8285 detection of uninitialized objects from spare memory as live.
8287 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8290 * Makefile.in (.PHONY): versioclean -> versionclean.
8292 Remove unused external symbols.
8293 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8294 * window.c (Qwindow_valid_p, decode_valid_window):
8295 Now static, not extern.
8296 * data.c (Qinterval): Remove; unused.
8297 (syms_of_data): Do not define 'interval'.
8298 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8299 * window.h (decode_valid_window):
8302 * character.c, charset.c, chartab.c: Use bool for booleans.
8303 * character.c (lisp_string_width, string_count_byte8)
8304 (string_escape_byte8):
8305 * charset.c (charset_map_loaded, load_charset_map, read_hex):
8306 (load_charset_map_from_file, map_charset_chars)
8307 (Fdefine_charset_internal, define_charset_internal)
8308 (Fdeclare_equiv_charset, find_charsets_in_text)
8309 (Ffind_charset_region, char_charset, Fiso_charset):
8310 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
8311 (sub_char_table_set, sub_char_table_set_range)
8312 (char_table_set_range, optimize_sub_char_table)
8313 (map_sub_char_table):
8314 Use bool for boolean.
8315 * character.c (str_to_unibyte): Omit last boolean argument; it was
8316 always 0. All callers changed.
8317 * character.h, charset.h: Adjust to match previous changes.
8318 * character.h (char_printable_p): Remove decl of nonexistent function.
8319 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8320 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8321 are all boolean, so make them single-bit bitfields.
8323 * lisp.h (ASET): Remove attempt to detect side effects.
8324 It was meant to be temporary and it often doesn't work,
8325 because when IDX has side effects the behavior of IDX==IDX
8326 is undefined. See Stefan Monnier in
8327 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8329 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8331 * lisp.h (functionp): New function (extracted from Ffunctionp).
8332 (FUNCTIONP): Use it.
8333 * eval.c (Ffunctionp): Use it.
8335 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8337 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8338 as that's faster and simpler than static storage. Don't bother
8339 with the g_main_context_query overhead if g_main_context_pending
8340 says no events are pending.
8341 (gfds, gfds_size): Remove these static vars.
8342 (xgselect_initialize): Remove; no longer needed.
8343 All uses and decls removed.
8345 * emacs.c (fatal_error_signal_hook): Remove.
8346 All uses removed. This leftover from old code was always 0.
8348 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8349 * casefiddle.c (casify_object, casify_region):
8350 * casetab.c (set_case_table):
8351 * category.c, category.h (word_boundary_p):
8352 * category.h (CHAR_HAS_CATEGORY):
8353 Use bool for booleans, instead of int.
8355 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8357 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8359 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8361 On assertion failure, print backtrace if available.
8362 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8363 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8364 * Makefile.in (LIB_EXECINFO): New macro.
8367 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8368 * bytecode.c (exec_byte_code):
8369 * callint.c (check_mark, Fcall_interactively):
8370 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8371 (getenv_internal, sync_process_alive, call_process_exited):
8372 * lisp.h (USE_SAFE_ALLOCA):
8373 Use bool for booleans, instead of int.
8374 * lisp.h, process.h: Adjust prototypes to match above changes.
8375 * callint.c (Fcall_interactively): Don't assume the mark's
8376 offset fits in 'int'.
8378 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8380 * buffer.c, buffer.h: Use bool for boolean.
8381 * buffer.c (reset_buffer_local_variables)
8382 (buffer_lisp_local_variables, Fset_buffer_modified_p)
8383 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
8384 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
8385 (overlay_touches_p, overlay_strings, Foverlay_put)
8386 (report_overlay_modification, call_overlay_mod_hooks):
8387 (mmap_enlarge, mmap_set_vars):
8388 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8389 Use bool for booleans, instead of int.
8390 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8391 since the 1-or-0 return value is always ignored anyway.
8392 (mmap_initialized_p):
8393 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8394 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8396 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8398 * bidi.c: Use bool for boolean.
8399 This is a bit more readable, and makes the text segment of bidi.o
8400 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8401 Presumably it's faster too.
8402 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8404 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8405 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8406 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8407 (bidi_explicit_dir_char, bidi_level_of_next_char)
8408 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8409 Use bool for booleans, instead of int.
8410 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8411 (bidi_unshelve_cache): Adjust decls to match code.
8413 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8415 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8418 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8420 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8421 * atimer.h: Include <stdbool.h>.
8423 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8425 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8426 compile time tests instead of run time tests on systems that do
8428 (FRAME_MAC_P): Remove leftover from deleted code.
8429 * frame.c (syms_of_frame): Remove leftover from deleted code.
8431 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8433 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8435 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8437 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8438 Otherwise, the compiler complains about (A?B:C) where B is void
8439 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8440 (fontset_add): Return void, for FONTSET_ADD.
8442 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8444 * alloc.c: Use bool for booleans.
8445 (gc_in_progress, abort_on_gc)
8446 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8447 (dont_register_blocks) [GC_MALLOC_CHECK]:
8448 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8449 (check_string_bytes, make_specified_string, memory_full)
8450 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8451 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8452 (mark_stack, valid_pointer_p, make_pure_string)
8453 (Fgarbage_collect, survives_gc_p, gc_sweep):
8454 Use bool for booleans, instead of int.
8455 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8456 Remove unused local.
8457 * alloc.c (PURE_POINTER_P):
8458 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8459 * editfns.c (Fformat):
8460 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8462 * fns.c (sweep_weak_table):
8463 * lisp.h (suppress_checking, push_message, survives_gc_p)
8464 (make_pure_string, gc_in_progress, abort_on_gc):
8465 * lread.c (readchar, read1):
8466 * print.c (Fprin1_to_string):
8467 * xdisp.c (push_message):
8468 Use bool for booleans affected directly or indirectly by
8471 Make recently-introduced setters macros.
8472 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8473 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8474 (set_fontset_default, set_fontset_fallback): Rename from their
8475 upper-case counterparts, and make them functions rather than macros.
8476 This is more consistent with the other recently-introduced setters.
8477 These don't need to be inline, since they're local.
8479 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8481 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8482 the loop (Bug#12247).
8484 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8486 * lisp.h (vcopy): Use memcpy rather than our own loop.
8487 This fixes a performance regression introduced by the recent
8488 addition of vcopy. This means 'vcopy' will need to be modified
8489 for a copying collector, but that's OK. Also, tighten the
8490 checking in the assertion.
8492 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8494 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8495 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8496 non-base glyph for the width of the base character, according to
8497 what x_draw_composite_glyph_string_foreground expects.
8498 Generate WADJUST value according to composition_gstring_width's
8499 expectations, to produce correct width of the composed character.
8500 Reverse the sign of the DU offset produced by ScriptPlace.
8502 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8504 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8506 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8508 Avoid direct writes to contents member of struct Lisp_Vector.
8509 * lisp.h (vcopy): New function to copy data into vector.
8510 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8511 * fns.c (Ffillarray): Use ASET.
8512 * keyboard.c (timer_check_2): Use AREF and ASET.
8513 (append_tool_bar_item, Frecent_keys): Use vcopy.
8514 * lread.c (read_vector): Use ASET.
8515 * msdos.c (Frecent_doskeys): Use vcopy.
8516 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8517 (Finternal_merge_in_global_face): Use ASET and vcopy.
8518 * xfont.c (xfont_list_pattern): Likewise.
8520 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8522 * window.c (Fwindow_point): For the selected window always return
8523 the position of its buffer's point.
8524 (Fset_window_point): For the selected window always go in its
8525 buffer to the specified position.
8527 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8529 Setter macros for fontsets.
8530 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8531 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8532 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8535 2012-08-20 Glenn Morris <rgm@gnu.org>
8537 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8538 Don't assume that `ln -f' works.
8540 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8542 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8543 and later about non-assignments with no effect. See discussion at
8544 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8547 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8549 Inline setter functions for Lisp_Objects slots of struct specbinding.
8550 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8553 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8555 * window.c (select_window): Always make selected window's buffer
8558 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8560 Use AREF and ASET for docstrings of category tables.
8561 * category.h (CATEGORY_DOCSTRING): Use AREF.
8562 (SET_CATEGORY_DOCSTRING): Use ASET.
8563 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8565 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8567 Inline setter functions for hash table members.
8568 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8569 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8570 (set_hash_key_and_value, set_hash_index, set_hash_next)
8571 (set_hash_hash): New functions.
8572 * charset.c, fns.c: Adjust users.
8574 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8576 Inline getter and setter functions for per-buffer values.
8577 * buffer.h (per_buffer_default, set_per_buffer_default)
8578 (per_buffer_value, set_per_buffer_value): New functions.
8579 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8580 * buffer.c, data.c: Adjust users.
8582 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8584 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8586 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8588 Rely on <config.h> + <unistd.h> to declare 'environ',
8589 as gnulib does this if the system doesn't.
8590 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8591 Remove declaration. MS-Windows declares it on stdlib.h which is
8592 included by conf_post.h.
8593 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8594 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8595 * vm-limit.c: Include <unistd.h>, for 'environ'.
8597 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8598 (start_of_data): Remove decl; mem-limits.h provides it.
8600 * xdisp.c (handle_invisible_prop): Make it a bit faster
8601 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8603 2012-08-19 Chong Yidong <cyd@gnu.org>
8605 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8608 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8610 * .gdbinit: Use call instead of set when calling a function in the
8613 * data.c (set_internal): Don't use set_blv_found.
8614 (Fkill_local_variable): Likewise.
8616 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8618 * nsfont.m (ns_ascii_average_width): Ensure the string
8619 ascii_printable is initialized with a null-terminated character
8620 array. Otherwise, it can contain undesired extra characters.
8622 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8624 port new setting code to Sun C 5.8 2005/10/13
8625 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8626 Return void, not Lisp_Object. Otherwise, the compiler
8627 complains about (A?B:C) where B is void and C is Lisp_Object
8628 when compiling CHAR_TABLE_SET, due to the recent change to
8629 the API of sub_char_table_set_contents.
8631 2012-08-18 Chong Yidong <cyd@gnu.org>
8633 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8634 for the string case (Bug#3874).
8636 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8638 * buffer.h (BSET): Remove (Bug#12215).
8639 Replace all uses with calls to new setter functions.

9571 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9572 checking subscripts; problem introduced with the recent
9573 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9574 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9575 since it's used in non-static inline functions now.
9577 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

9604 (INLINE_HEADER_END): New macros.
9605 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9627 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9629 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9630 This how ASET and AREF are supposed to work, and makes
9631 it easier to think about future improvements. See
9632 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9633 * charset.h (set_charset_attr): New function.

10014 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
10015 (w32_kbd_patch_key, key_event): Use the codepage returned by
10016 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

10018 w32_console_unicode_input is non-zero.
10020 * w32console.c: Include w32heap.h.

10043 2012-07-27 Eli Zaretskii <eliz@gnu.org>
10045 * alloc.c (listn): Fix the order the arguments are consed onto the
10048 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10049 enumeration constants, as PURE and HEAP are too general, and clash
10050 with other headers and sources, such as gmalloc.c and the
10051 MS-Windows system headers. All users changed.
10053 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10055 Revert last save_excursion_save and save_excursion_restore changes.
10056 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
10057 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
10059 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10061 Fix recently-introduced typos in Windows port.

10064 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10066 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10068 Improve GDB symbol export (Bug#12036).
10069 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10070 arms of an 'if', not using conditional expressions; otherwise GDB
10071 complains about the types in the unevaluated arm when the argument
10072 is an integer literal.
10073 (xgetint): Simplify expression.
10074 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10075 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10076 Zaretskii in <http://bugs.gnu.org/12036#13>.
10077 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10078 needed now that we have gdb_make_enums_visible.
10079 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10080 (enum enum_USE_LSB_TAG):
10081 New enum types, packaging up enums that need to be exported to GDB.
10083 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10085 Utility function to make a list from specified amount of objects.
10086 * lisp.h (enum constype): New datatype.
10087 (listn): New prototype.
10088 * alloc.c (listn): New function.
10089 (Fmemory_use_count, syms_of_alloc): Use it.

10104 Fast save_excursion_save and save_excursion_restore.
10105 * lisp.h (struct Lisp_Excursion): New data type.
10106 (PVEC_EXCURSION): New pseudovector type.
10107 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10108 to deal with it. Adjust comments.
10109 (init_marker, attach_marker): New prototype.
10110 (unchain_marker): Adjust prototype.
10111 * marker.c (attach_marker): Change to global.

10122 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10123 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10124 emacs.c, as this is a more-suitable home. Had this been done earlier
10125 the fix for 12036 would have avoided some of the problems noted in
10126 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10127 would have been more obvious.
10128 * emacs.c: Do not include <verify.h>; no longer needed.
10129 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

10131 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10132 Remove; now done in lisp.h.
10133 * lisp.h (PUBLISH_TO_GDB): New macro.

10136 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10137 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10138 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10139 not be usable in #if. This simplifies things.
10141 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10143 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10145 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10147 Simplify export of symbols to GDB (Bug#12036).
10148 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10149 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10150 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10151 Adjust to changes in lisp.h and emacs.c, by using
10152 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10153 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10154 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10155 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10156 instead of gdb_valbits.
10157 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10158 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10159 instead of gdb_array_mark_flag.
10160 (xboolvector): Get size from $->size, not $->header.size.
10161 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10162 (xreload, hook-run, hookpost-run): Remove.
10163 * emacs.c: Include <verify.h>.
10164 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10165 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10167 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10168 (gdb_USE_LSB_TAG): New enum constants.
10169 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10170 Also define these as enum constants, so they're visible to GDB.
10171 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10172 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10173 as constants, so they're visible to GDB.
10174 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10175 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10176 Now enum constants, not macros, so they're visible to GDB.
10177 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10178 more convenient now. All uses changed.
10179 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10180 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10182 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

10185 * editfns.c (save_restriction_restore): Free restriction data.
10187 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10189 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10190 add argument, tune behavior, and adjust all callers.
10192 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10194 Use typedef for EMACS_INT, EMACS_UINT.
10195 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10196 than macros. This simplifies debugging in the usual case, since
10197 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10198 and it allows expressions involving EMACS_INT casts.
10199 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10201 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10203 * nsterm.m (ns_read_socket): Return early if there is a modal
10204 window (Bug#12043).
10206 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10208 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10209 that FOCUS-FRAME can be omitted.
10211 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10213 Adjust buffer text indirection counters at the end of Fkill_buffer.
10214 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10215 buffer is definitely dead. This should really fix an issue reported
10216 by Christoph Scholtes again. (Bug#12007).
10217 (init_buffer_once): Initialize indirection counters of
10218 buffer_defaults and buffer_local_symbols (for sanity and safety).
10220 2012-07-24 Eli Zaretskii <eliz@gnu.org>
10222 * xdisp.c (init_iterator): Don't compute dimensions of truncation
10223 and continuation glyphs on tooltip frames, leave them at zero.
10224 Avoids continued lines in tooltips. (Bug#11832)
10226 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
10228 Simplify copy_overlay.
10229 * buffer.c (copy_overlay): Simplify. Use build_marker.

10234 * print.c (print_object): Don't crash when a frame's name is nil
10235 or invalid. (Bug#12025)
10237 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10238 it signals an error when a tooltip frame is being created.
10240 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10242 Cleanup miscellaneous objects allocation and initialization.
10243 * alloc.c (allocate_misc): Change to static. Add argument to
10244 specify the subtype. Adjust comment and users.
10245 (build_overlay): New function.
10246 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10247 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
10248 (allocate_misc): Remove prototype.
10249 (build_overlay): Add prototype.
10251 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10253 Swap buffer text indirection counters in Fbuffer_swap_text.
10254 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10255 This avoids crash reported by Christoph Scholtes at
10256 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10258 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10260 * nsmenu.m (Popdown_data): New struct.
10261 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
10263 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
10264 (initWithContentRect): Make imgView and contentView non-static
10265 and autorelease them. Also autorelease img and matrix (Bug#12005).
10266 (dealloc): Remove (Bug#12005).
10268 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10270 Adjust consing_since_gc when objects are explicitly freed.
10271 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
10272 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

10279 (live_buffer, set_marker_internal): New function.
10280 (Fset_marker, set_marker_restricted): Use set_marker_internal.
10281 (set_marker_both, set_marker_restricted_both): Use live_buffer.
10283 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
10285 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
10286 as it's limited by the amount of memory, not by INT_MAX.
10288 2012-07-21 Eli Zaretskii <eliz@gnu.org>
10290 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

10295 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
10296 info.dwItemData. Fixes crashes on 64-bit Windows.
10297 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
10299 2012-07-21 Jan Djärv <jan.h.d@swipnet.se>

10308 on a dead frame (Bug#11984).
10310 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

10336 * lisp.h (consing_since_gc, gc_relative_threshold)
10337 (memory_full_cons_threshold): Revert declaration.
10338 (maybe_gc): Remove prototype, define as inline.
10339 * alloc.c: Remove old commented-out code.
10340 (consing_since_gc, gc_relative_threshold)
10341 (memory_full_cons_threshold): Revert to global.
10342 (maybe_gc): Remove.
10344 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>
10346 Simple wrapper for make_unibyte_string, adjust font_open_by_name.

10350 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
10351 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
10352 Adjust users accordingly.
10353 * font.h (font_open_by_name): Adjust prototype.
10355 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>
10357 Cleanup calls to Fgarbage_collect.

10372 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
10373 'for_each_per_buffer_object_at'.
10374 All uses changed. It's better to use upper-case for macros that
10375 cannot be implemented as functions, to give the reader a clue
10376 that they're special.
10378 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
10380 * alloc.c (Fgarbage_collect): Tweak docstring.

11014 * s/aix4-2.h (unix): Remove; no longer needed.
11016 EMACS_TIME simplification (Bug#11875).
11017 This replaces macros (which typically do not work in GDB)
11018 with functions, typedefs and enums, making the code easier to debug.
11019 The functional style also makes code easier to read and maintain.
11020 * systime.h: Include <sys/time.h> on all hosts, not just if
11021 WINDOWSNT, since 'struct timeval' is needed in general.
11022 (EMACS_TIME): Now a typedef, not a macro.

11036 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
11037 (add_emacs_time, sub_emacs_time): New functions.
11038 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

11055 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
11056 (menu_separator_name_p):
11057 * nsmenu.m (ns_update_menubar):
11058 Prefer memcmp to strncmp when either will do.
11059 * nsterm.m: Include <ftoastr.h>.
11061 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11062 Prefer snprintf to strncpy.
11063 * nsterm.m (ns_term_init):
11064 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11065 * nsterm.m (ns_term_init):
11066 Avoid the need for strncpy, by using build_string or
11067 make_unibyte_string directly. Use dtoastr, not snprintf.
11068 * process.c (Fmake_network_process): Diagnose service names that
11069 are too long, rather than silently truncating them or creating
11070 non-null-terminated names.
11071 (Fnetwork_interface_info): Likewise, for interface names.
11072 * sysdep.c (system_process_attributes) [GNU_LINUX]:
11073 Prefer sprintf to strncat.
11074 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

11086 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
11087 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

11105 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11106 argument, adjust users accordingly. Use build_pure_c_string where

11109 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11110 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

11142 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11143 O_RDONLY already includes it).
11145 Stop ns builds setting the EMACSLOADPATH environment variable.

11147 Now it does not set EMACSLOADPATH, just returns the load-path string.
11148 * nsterm.h: Update accordingly.
11149 * lread.c [HAVE_NS]: Include nsterm.h.
11150 (init_lread) [HAVE_NS]: Use ns_load_path.

11160 (ns_init_paths): Do not set EMACSPATH.

11220 Move marker debugging code under MARKER_DEBUG.
11221 * marker.c (MARKER_DEBUG): Move marker debugging code under
11222 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11223 for bootstrap with --enable-checking (~3x slowdown reported

11263 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11264 Remove unused local.
11265 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11266 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11267 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11268 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11269 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11270 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11271 Fix pointer signedness problem.
11272 * xfaces.c (FRAME_X_FONT_TABLE):
11273 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11275 2012-07-07 Glenn Morris <rgm@gnu.org>
11277 * lread.c (load_path_check): New function, split from init_lread.
11278 (init_lread): Reorganize. Motivation:
11279 If EMACSLOADPATH is set, check/warn about that rather than the
11280 defaults, which we are not going to use. Hence we can remove
11281 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11282 Don't warn if site-lisp directories are missing.
11283 If not installed, start from a blank load-path, since
11284 PATH_LOADSEARCH refers to the eventual installation directories.
11286 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11288 Support truncation and continuation glyphs on GUI frames, when
11289 fringes are disabled. (Bug#11832)
11290 * xdisp.c (init_iterator): Get dimensions of truncation and
11291 continuation glyphs even if on GUI frames.
11292 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11293 or both, are absent.
11294 (start_display, move_it_in_display_line_to): Handle the case of a
11295 GUI frame without a fringe to display continuation or truncation
11297 (insert_left_trunc_glyphs): Support GUI frames: make sure
11298 truncation glyphs overwrite enough glyphs from the current line to
11299 have sufficient space in pixels.
11300 (display_line): Support truncation and continuation glyphs on GUI
11301 frames. If some spare pixels are left on the line after inserting
11302 the truncation glyphs, fill that space with a stretch glyph of a
11303 suitably computed width.
11305 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11306 produce_glyphs, to support GUI sessions.
11308 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11310 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11312 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11314 Do not require float-time's arg to fit in time_t (Bug#11825).
11315 This works better on hosts where time_t is unsigned, and where
11316 float-time is applied to the (negative) difference between two times.
11317 * editfns.c (decode_time_components): Last arg is now double *,
11318 not int *, and means to store all the result as a double, without
11319 worrying about whether the seconds part fits in time_t.
11320 All callers changed.
11321 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11322 All callers changed.
11323 (Ffloat_time): Do not fail merely because the specified time falls
11324 outside of time_t range.
11326 2012-07-07 Glenn Morris <rgm@gnu.org>
11328 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11329 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11330 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11332 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11334 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11335 Update dependencies.
11337 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11339 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11341 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
11342 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
11343 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11344 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11345 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11346 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11348 * xfont.c (compare_font_names): Redo to omit the need for casts.
11350 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11352 * xfns.c (Fx_change_window_property): Doc fix.
11353 * w32fns.c (Fx_change_window_property): Doc fix.
11355 * w32fns.c (Fx_window_property): Accept the same arguments as the
11356 X Windows version. Doc fix.
11357 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11359 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11360 Eli Zaretskii <eliz@gnu.org>
11362 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11363 Windows-specific code from nt/config.nt moved here.
11364 Obsolete settings removed.
11366 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11368 * process.c: Avoid unnecessary calls to gettime.
11369 (wait_reading_process_output): Don't get the time of day
11370 when gobbling data immediately and not waiting, as there's no need
11371 for it in that case. This removes a FIXME.
11373 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11375 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11376 is defined (Bug#11768).
11378 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11380 Fix marker debugging code.
11381 * marker.c (byte_char_debug_check): Do not perform the check
11382 if buffer is not multibyte.
11383 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11384 Call byte_char_debug_check with correct arguments.
11386 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11388 Compile marker debugging code only if ENABLE_CHECKING is defined.
11389 * marker.c (byte_char_debug_check, count_markers):
11390 Use only if ENABLE_CHECKING is defined.
11391 (byte_debug_flag): Remove.
11392 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11393 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11395 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11397 Avoid code repetition in marker-related functions.
11398 * marker.c (attach_marker): New function.
11399 (Fset_marker, set_marker_restricted, set_marker_both)
11400 (set_marker_restricted_both): Use it.
11401 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
11402 Consistently rename charno to charpos.
11403 (marker_position): Add eassert.
11404 (marker_byte_position): Convert to eassert.
11406 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11408 Simplify list operations in unchain_overlay and unchain_marker.
11409 * buffer.c (unchain_overlay): Simplify. Add comment.
11410 * marker.c (unchain_marker): Simplify. Fix comments.
11412 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11414 Introduce fast path for the widely used marker operation.

11417 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
11418 * composite.c (autocmp_chars): Likewise.
11419 * editfns.c (buildmark): Remove.
11420 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11421 (save_restriction_save): Use build_marker.
11422 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11423 * window.c (save_window_save): Likewise.
11425 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11427 Do not use Fdelete_overlay in delete_all_overlays
11428 to avoid redundant calls to unchain_overlay.
11429 * buffer.c (drop_overlay): New function.
11430 (delete_all_overlays, Fdelete_overlay): Use it.
11431 * minibuf.c (get_minibuffer): Fix comment.
11433 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11435 Port to OpenBSD 5.1 amd64.
11436 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11437 This is needed for OpenBSD, and should be harmless on all BSD systems.
11438 Also, include <sys/sysctl.h>, as it should be available on all
11439 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11440 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11441 use p_pid member, not kp_proc.pid.
11443 2012-07-06 Glenn Morris <rgm@gnu.org>
11445 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11447 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11449 More xmalloc and related cleanup.
11450 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

11458 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11460 Omit needless casts involving void * pointers and allocation.
11461 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11462 as the former is more robust if P's type is changed.
11463 Prefer xzalloc to xmalloc + memset 0.
11464 Simplify malloc-or-realloc to realloc.
11465 Don't worry about xmalloc returning a null pointer.
11466 Prefer xstrdup to xmalloc + strcpy.
11467 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11469 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11470 alloca of a constant.
11472 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11474 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11475 hscroll is larger than the line width. Fixes long and futile
11476 looping inside extend_face_to_end_of_line (on a TTY) producing
11477 glyphs that are not needed and thrown away.
11479 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11481 * marker.c (set_marker_restricted_both): Simplify by using
11484 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11486 * editfns.c (region_limit): Simplify by using clip_to_bounds.
11488 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
11490 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
11491 not defined (Bug#11768).
11492 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
11493 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
11494 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
11495 followed by gtk_box_set_homogeneous (Bug#11768).
11496 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11497 (update_theme_scrollbar_width, xg_create_scroll_bar):
11498 Use gtk_scrollbar_new (Bug#11768).
11499 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11500 (is_box_type): New function (Bug#11768).
11501 (xg_tool_item_stale_p): Call is_box_type.
11502 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11503 with default display (Bug#11768).
11505 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11507 * xdisp.c (window_hscroll_limited): New function.
11508 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11509 coordinates when window's hscroll is set to insanely large
11510 values. (Bug#11857)
11512 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11514 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
11515 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

11573 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11575 * fileio.c (time_error_value): Check the right error number.
11576 Problem reported by Troels Nielsen in
11577 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11579 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11581 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11582 This should be fixed in a better way; see Eli Zaretskii in
11583 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11584 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11586 * fileio.c (time_error_value): Rename from special_mtime.
11587 The old name's problems were noted by Eli Zaretskii in
11588 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11590 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11591 This variable's comment says Emacs needs at least one GDB-visible
11592 symbol of type enum pvec_type, to work around GDB problems.
11593 The symbol's value doesn't matter.
11595 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11596 that causes compilation to fail on pre-C99 compilers.
11598 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11600 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11601 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11603 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11605 * buffer.c (init_buffer_once): Fix initialization of
11606 headers for buffer_defaults and buffer_local_symbols.
11607 Reported by Juanma Barranquero <lekktu@gmail.com>.
11609 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11611 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11612 * lisp.h (enum pvec_type): Use fewer bits.
11613 (PSEUDOVECTOR_SIZE_BITS): New constant.
11614 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11615 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11616 change in pvec_type.
11617 (PSEUDOVECTOR_TYPEP): New macro.
11618 (TYPED_PSEUDOVECTORP): Use it.
11619 * fns.c (internal_equal): Adapt code to extract pvectype.
11620 * emacs.c (gdb_pvec_type): Update type.
11621 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11622 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11623 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11624 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11625 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11626 abusing vector->header.next.nbytes.
11627 (live_vector_p): Use PVEC_TYPE.
11628 (mark_object): Adapt code to extract pvectype. Use switch.
11630 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11632 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11633 Tighten new eassert a bit.
11635 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11637 Fix compilation with --enable-gcc-warnings and -O1
11638 optimization level.
11639 * doprnt.c (doprnt): Change type of tem to int, initialize
11640 to avoid compiler warning. Add eassert.
11641 * search.c (simple_search): Initialize match_byte to avoid
11642 compiler warning. Add eassert.
11644 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11646 Avoid weird behavior with large horizontal scrolls.
11647 Without this change, for example, large hscroll values would
11648 mess up Emacs's display on Fedora 15 x86, presumably due to
11649 overflows in int calculations in the display code.
11650 Also, if buffers had long lines, Emacs would freeze.
11651 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11652 (set_window_hscroll): New function, containing the old guts of
11653 Fset_window_hscroll. Return the clipped value.
11654 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11655 This avoids the need to check against PTRDIFF_MAX.
11657 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11659 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11661 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11663 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11665 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11666 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11667 since GCC 4.4.6 issues a bogus warning for them.
11669 Fix bugs in file timestamp newness comparisons.
11670 * fileio.c (Ffile_newer_than_file_p):
11671 * lread.c (Fload): Use full timestamp resolution of files,
11672 not just the 1-second resolution, so that files that are only
11673 slightly newer still count as newer.
11674 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11675 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11677 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11679 * fileio.c: Improve handling of file time marker. (Bug#11852)
11680 (special_mtime): New function.
11681 (Finsert_file_contents, Fverify_visited_file_modtime):
11682 Use it to set special mtime values consistently.
11684 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11686 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11687 marker for non-existing file. (Bug#11852)
11689 2012-07-03 Glenn Morris <rgm@gnu.org>
11691 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11692 and did not make it into globals.h).
11694 2012-07-03 Tom Tromey <tromey@redhat.com>
11696 * window.c (Fset_window_margins, Fset_window_fringes)

11732 2012-07-03 Glenn Morris <rgm@gnu.org>
11734 * lisp.h (Frandom): Make it visible to C.
11735 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11736 buffer for invisible buffers. (Bug#1229)
11738 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11740 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11741 values which aren't power of 2.
11742 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11743 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11746 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11748 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11750 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11752 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11754 * alloc.c (allocate_vector_block): Remove redundant
11755 calls to mallopt if DOUG_LEA_MALLOC is defined.
11756 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11757 avoid calls to mallopt if zero_vector is returned.
11759 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11761 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11762 is enabled, avoid dereferencing NULL current_sblock if
11765 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11767 Cleanup basic buffer management.
11768 * buffer.h (struct buffer): Change layout to use generic vector
11769 marking code. Fix some comments. Change type of 'clip_changed'
11770 to bitfield. Remove unused #ifndef old.
11771 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11772 (GET_OVERLAYS_AT): Fix indentation.
11773 (for_each_per_buffer_object_at): New macro.
11774 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11775 (Fbuffer_local_variables): Use it.
11776 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11777 * alloc.c (allocate_buffer): Adjust to match new layout of
11778 struct buffer. Fix comment.
11779 (mark_overlay): New function.
11780 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11781 Lisp area of struct buffer.
11782 (mark_object): Use it. Adjust marking of misc objects
11783 and related comments.
11785 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11787 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11788 wrapper that is not needed because the wrapped code is a no-op (zero
11789 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11790 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11792 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11794 * alloc.c (mark_buffer): Simplify. Remove prototype.
11795 (mark_object): Add comment. Reorganize marking of vector-like
11796 objects. Use CHECK_LIVE for all vector-like objects except buffers
11797 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11798 Avoid redundant calls to mark_vectorlike for bool vectors.
11800 2012-06-30 Glenn Morris <rgm@gnu.org>
11802 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11804 * epaths.in (PATH_SITELOADSEARCH): New.
11805 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11806 This is rather than relying on --enable-locallisppath elements
11807 having "site-lisp" in their names. (Bug#10208#25, 11658)
11809 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11811 * w32proc.c (sys_select): Accept and ignore one more argument.
11813 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11815 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11816 (pselect) [!MS_DOS]: Redirect to sys_select.
11818 * sysdep.c: Don't include dos.h and dosfns.h.
11820 * process.c (sys_select):
11821 * msdos.c (sys_select): Accept one more argument and ignore it.
11823 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11824 adapt data types and code to that.
11827 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11828 which clashes with the gnulib function of the same name.
11830 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11832 * font.c (font_style_to_value, font_style_symbolic)
11833 (font_prop_validate_style): Add type checks for values in
11836 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11838 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11841 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11843 * xdisp.c (try_window_id): Undo last change.
11845 * w32.c (getwd): Adjust commentary about startup_dir.
11846 (init_environment): Always call sys_access, even in non-MSVC
11847 builds. Don't chdir to the directory of the Emacs executable.
11848 This undoes code from 1997 which was justified by the need to
11849 "avoid conflicts when removing and renaming directories". But its
11850 downside was that every relative file name was being interpreted
11851 relative to the directory of the Emacs executable, which can never
11852 be TRT. In particular, it broke sys_access when called with
11853 relative file names.
11854 (sys_access): Map GetLastError to errno.
11856 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11862 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11865 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

11868 Add QUIT to make the loop interruptible.
11870 2012-06-29 Glenn Morris <rgm@gnu.org>
11872 * charset.c (init_charset): Make lack of etc/charsets fatal.

11880 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11881 undefined. Convert from xassert to eassert.
11882 * nsmenu.m: Convert from xassert to eassert.
11883 * nsterm.m: Likewise.
11885 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11889 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11891 Avoid integer overflow on scroll-left and scroll-right.
11892 * window.c (HSCROLL_MAX): New macro.
11893 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11894 overflow when requested scroll falls outside ptrdiff_t range.
11896 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11898 * window.h (struct window): Change type of 'hscroll',
11899 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11900 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11901 Adjust users accordingly.
11902 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11903 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11904 from EMACS_INT to ptrdiff_t.

11924 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11925 adjust comments accordingly.

12046 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12048 Use sprintf return value instead of invoking strlen on result.
12049 In the old days this wasn't portable, since some sprintf
12050 implementations returned char *. But they died out years ago and
12051 Emacs already assumes sprintf returns int.
12052 Similarly for float_to_string.
12053 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

12059 * xdisp.c (message_dolog):
12060 * xfns.c (syms_of_xfns):
12061 Use sprintf or float_to_string result to avoid need to call strlen.
12062 * data.c (Fnumber_to_string):
12063 Use make_unibyte_string, since the string must be ASCII.
12064 * lisp.h, print.c (float_to_string): Now returns int length.
12065 * term.c (produce_glyphless_glyph):
12066 Use sprintf result rather than recomputing it.
12068 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12069 * Makefile.in (ALL_CFLAGS):
12070 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

12097 * xfns.c (x_window): Remove redundant cast.
12099 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12101 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12102 `const char *' to `char *' to avoid compiler warning.
12104 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12106 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12107 instead of truncating it to 63 (admittedly a generous limit).
12109 * process.c: Fix spelling and caps in comments.
12111 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12113 * emacs.c (setpgrp): Remove definition, unused.

12160 Remove unnecessary forward decls.
12162 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

12170 This improves on the previous patch, which introduced a bug
12171 when time_t is unsigned and as wide as intmax_t.
12172 See <http://bugs.gnu.org/9000#51>.
12174 2012-06-23 Eli Zaretskii <eliz@gnu.org>

12199 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
12200 last argument of make_unibyte_string.
12202 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
12203 language ID in the event parameters.
12205 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12206 event.code, not the obscure "character set ID".
12208 2012-06-23 Chong Yidong <cyd@gnu.org>
12210 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

12234 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
12235 Don't assume EMACS_TIME and struct timeval are the same type.
12237 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12239 Support higher-resolution time stamps (Bug#9000).
12240 The time stamps are only nanosecond-resolution at the C level,
12241 since that's the best that any real-world system supports now.
12242 But they are picosecond-resolution at the Lisp level, as that's
12243 easy, and leaves room for future OS improvements.
12245 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12248 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12249 Don't get current time unless it's needed.
12251 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12252 now provides it if it's absent.
12253 (start_atimer): Port to higher-res time stamps.
12254 Check for time stamp overflow. Don't get current time more
12255 often than is needed.
12257 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12258 Include systime.h, not time.h.
12259 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12261 * dired.c: Include stat-time.h.
12262 (Ffile-attributes): File times now have higher resolution.
12264 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12265 (struct image): Timestamp now has higher resolution.
12267 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12268 has at least microseconds now. All uses removed.
12269 (update_frame, update_single_window, update_window, update_frame_1)
12270 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12271 (duration_to_sec_usec): Remove; no longer needed.
12273 * editfns.c (time_overflow): Now extern.
12274 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12275 (float-time, Fformat_time_string, Fcurrent_time_string)

12279 (decode_time_components, lisp_seconds_argument): New functions.
12280 (make_time): Now static.
12281 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12282 Report an error if the time is invalid, rather than having the caller
12285 * fileio.c: Include <stat-time.h>
12286 (Fcopy_file): Copy higher-resolution time stamps.
12287 Prefer to set the time stamp via a file descriptor if that works.
12288 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12289 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12290 (Fvisited_file_modtime, Fset_visited_file_modtime):
12291 Support higher-resolution time stamps.
12293 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12295 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12297 * image.c (prepare_image_for_display, clear_image_cache)
12298 (lookup_image): Port to higer-resolution time stamps.
12300 * keyboard.c (start_polling, bind_polling_period):
12301 Check for time stamp overflow.
12302 (read_char, kbd_buffer_get_event, timer_start_idle)
12303 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12304 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12305 Port to higher-resolution time stamps. Do not assume time_t is signed.
12306 (decode_timer): New function. Timers are now vectors of length 9,
12307 not 8, to accommodate the picosecond component.
12308 (timer_check_2): Use it.
12310 * nsterm.m (select_timeout, timeval_subtract): Remove.
12311 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12312 as they're a bit more accurate and handle overflow better.
12313 (ns_select): Change prototype to be compatible with pselect.
12314 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12315 * nsterm.h (ns_select): Adjust prototype.
12317 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12318 us-resolution time stamps.
12319 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12321 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12323 * lisp.h (time_overflow): New decl.
12324 (wait_reading_process_output): First arg is now intmax_t, not int,
12325 to accommodate larger waits.
12327 * process.h (struct Lisp_Process.read_output_delay):
12328 Now counts nanoseconds, not microseconds.
12329 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12331 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12332 (wait_reading_process_output):
12333 Port to ns-resolution time stamps.
12334 (Faccept_process_output, wait_reading_process_output):
12335 Check for time stamp overflow. Do not assume time_t is signed.
12336 (select_wrapper): Remove; we now use pselect.
12337 (Fprocess_attributes): Now generates ns-resolution time stamps.
12339 * sysdep.c: Include utimens.h. Don't include utime.h
12340 or worry about struct utimbuf; gnulib does that for us now.
12341 (gettimeofday): Remove; gnulib provides a substitute.
12342 (make_timeval): New function.
12343 (set_file_times): Now sets ns-resolution time stamps.
12344 New arg FD; all uses changed.
12345 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12346 (system_process_attributes):
12347 Now returns ns-resolution time stamp. All uses changed.
12348 Check for time stamp overflow.
12350 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12351 provides a substitute now.
12353 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12354 since it guarantees struct timespec.
12355 (EMACS_TIME): Now struct timespec, so that we can support
12356 ns-resolution time stamps.
12357 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12358 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12359 (EMACS_USECS): Remove.
12360 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12361 so multiply the arg by 1000 before storing it.
12362 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12364 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12365 Port to ns-resolution time stamps.
12366 (EMACS_TIME_NEG_P): Remove; replaced by....

12369 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12370 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12371 (make_timeval, make_lisp_time, decode_time_components): New decls.
12372 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12373 that it mishandled time_t overflow. You can't compare by subtracting!
12374 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12375 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12377 * term.c: Include <sys/time.h>.
12378 (timeval_to_Time): New function, for proper overflow wraparound.
12379 (term_mouse_position, term_mouse_click): Use it.
12381 * undo.c (record_first_change): Support higher-resolution time stamps
12382 in the undo buffer.
12383 (Fprimitive_undo): Use them when restoring time stamps.
12385 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12386 (w32_get_internal_run_time):
12387 Port to higher-resolution Emacs time stamps.
12388 (ltime): Now accepts single 64-bit integer, as that's more convenient
12391 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12393 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12394 for compatibility with pselect. Support ns-resolution time stamps.
12396 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12398 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12399 Check for time stamp overflow, and support ns-resolution time stamps.
12401 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12402 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12403 (timeval_subtract): Remove; no longer needed.
12404 (XTflash, XTring_bell, x_wait_for_event):
12405 Port to ns-resolution time stamps. Don't assume time_t is signed.
12407 2012-06-22 Chong Yidong <cyd@gnu.org>

12411 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12413 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12414 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12415 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12416 staticidx goes up to 1597 out of 1600 = 0x640.)
12418 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12420 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

12432 access to `contents' member of Lisp_Vector objects with AREF and ASET
12435 2012-06-19 Chong Yidong <cyd@gnu.org>
12437 * frame.c (delete_frame): When selecting a frame on a different
12438 text terminal, do not alter the terminal's top-frame.

12441 frame's selected window and its terminal's top-frame.
12442 (unwind_format_mode_line): Restore them.
12443 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12445 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12446 since tty frames can be explicitly named.
12447 (prepare_menu_bars): Likewise.
12449 * term.c (Ftty_top_frame): New function.
12451 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12454 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12455 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12456 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12457 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

12464 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12466 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12467 gets killed during executing of this function (Bug#11665).
12468 Try to always return Qt when the buffer has been actually killed.
12469 (Vkill_buffer_query_functions): In doc-string say that functions
12470 run by this hook should not change the current buffer.
12472 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12474 Fix recently-introduced process.c problems found by static checking.
12475 * process.c (write_queue_push, write_queue_pop, send_process):
12476 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12477 (write_queue_pop): Fix pointer signedness problem.
12478 (send_process): Remove unused local.
12480 2012-06-17 Chong Yidong <cyd@gnu.org>

12494 * lisp.h (eassert): Assume C89 or later.
12495 This removes the need for CHECK.
12496 (CHECK): Remove. Its comments about always evaluating its
12497 argument were confusing, as 'eassert' typically does not evaluate
12500 * coding.c (produce_chars): Use ptrdiff_t, not int.
12502 * xterm.c (x_draw_underwave): Check for integer overflow.
12503 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12676 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
12677 * alloc.c (make_number) [!defined make_number]:
12678 Remove, as lisp.h always defines this now.

12685 USE_LSB_TAG now is always defined to be either 0 or 1.
12687 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
12688 code works fine either way, and efficiency is not a concern here,
12689 as the union type is for debugging, not for production.
12690 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12691 Use an inline function on all platforms when using the union type,
12692 since this is simpler and 'static inline' can be used portably

12695 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12696 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12798 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12799 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12801 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12803 * alloc.c (allocate_vectorlike): Fix last change.
12805 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12807 Block-based vector allocation of small vectors.
12808 * lisp.h (struct vectorlike_header): New field `nbytes',
12809 adjust comment accordingly.
12810 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12811 to denote vector blocks. Adjust users (live_vector_p,

12834 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12836 * doprnt.c (doprnt): Truncate multibyte char correctly.
12837 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12838 would mishandle a string argument "Xc" if X was a multibyte
12839 character of length 2: it would truncate after X's first byte
12840 rather than including all of X.
12842 2012-06-06 Chong Yidong <cyd@gnu.org>
12844 * buffer.c (word_wrap): Doc fix.
12846 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

12891 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12893 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12894 Convert pctcpu and pctmem to Lisp float properly.
12895 Let the compiler fold better, as 100.0/0x8000 is exact.
12897 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12899 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12902 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
12904 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
12906 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12908 For a 'struct window', replace some Lisp_Object fields to
12909 bitfields where appropriate, remove unused fields.
12910 * window.h (struct window): Remove unused 'last_mark_x' and
12911 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12912 change its type from Lisp_Object to bitfield.
12913 Change type of 'force_start', 'optional_new_start',
12914 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12920 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12921 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12922 Use 'float' consistently, rather than 'float' in most places
12923 and 'double' in a couple of places.
12925 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12927 * xdisp.c (handle_stop): Detect whether we have overlay strings
12928 loaded by testing it->current.overlay_string_index to be
12929 non-negative, instead of checking whether n_overlay_strings is
12930 positive. (Bug#11587)
12932 2012-05-31 Chong Yidong <cyd@gnu.org>
12934 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12940 * search.c (search_buffer): Remove calls to
12941 r_alloc_inhibit_buffer_relocation, as it is now called by
12942 maybe_unify_char, which was the cause of relocation of buffer text
12945 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12947 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12948 for the duration of call to load_charset, to avoid problems with
12949 callers of maybe_unify_char that access buffer text through C
12952 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12953 decrement the inhibition flag, instead of just setting or
12956 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12958 Remove obsolete '#define static' cruft.
12959 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12960 This #undef was "temporary" in 2000; it is no longer needed
12961 now that '#define static' has gone away.
12962 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12963 (gray_bitmap_bits): Remove; no longer needed.
12964 All uses replaced with definiens.

12976 (safe_bcopy): Remove decl; no longer has that name.
12977 (main): Coalesce #if into single bit of code, for simplicity.
12978 Cast pointers to uintptr_t, since standard libraries want integers

13007 Do not create empty overlays with the evaporate property (Bug#9642).
13008 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13009 Bug#9642, but explicitly check that the buffer the overlay would
13010 be moved to is live and rearrange lines to make sure that errors
13011 will not put the overlay in an inconsistent state.
13012 (Fdelete_overlay): Cosmetics.
13014 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13016 * w32term.c (my_bring_window_to_top): New function.
13017 (x_raise_frame): Use handle returned by DeferWindowPos, which

13031 This avoids undefined behavior that might cause the eassert
13032 to not catch an out-of-range value.
13034 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13036 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

13051 Only r_alloc_inhibit_buffer_relocation needed to be added;
13052 the others were already declared.
13054 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13055 before checking whether it's out of range. Put the check inside
13057 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

13075 * search.c (search_buffer): Use it to inhibit relocation of buffer
13076 text while re_search_2 is doing its job, because re_search_2 is
13077 passed C pointers to buffer text. (Bug#11519)
13079 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13080 Update value to 24.
13082 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13083 state after an additional call to move_it_in_display_line_to, keep
13084 the values of it->max_ascent and it->max_descent found for the
13086 (pos_visible_p): Revert the comparison against bottom_y to what it
13087 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13090 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13092 Fix coding-related core dumps with gcc -ftrapv.
13093 The code was computing A - B, where A and B are pointers, and B is
13094 random garbage. This can lead to core dumps on platforms that
13095 have special pointer registers, and it also leads to core dumps on
13096 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13097 A - B only when B is initialized properly.
13098 * coding.c (coding_set_source, coding_set_destination): Return void.
13099 (coding_change_source, coding_change_destinations): New functions,
13100 with the old behaviors of coding_set_source and coding_set_destination.
13101 All callers that need an offset changed to use these new functions.
13103 2012-05-26 Glenn Morris <rgm@gnu.org>

13118 * w32inevt.c: Include termchar.h and window.h.
13119 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13120 moves, call note_mouse_highlight. If help_echo changed, call
13121 gen_help_event to produce help-echo message in the echo area.
13122 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13125 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13127 * lread.c (read1): Simplify slightly to avoid an overflow warning
13128 with GCC 4.7.0 on x86-64.
13130 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13132 * bidi.c (bidi_mirror_char): Revert last change: an int is
13133 definitely wide enough here.
13135 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

13149 Use int, not EMACS_INT, where int is wide enough.
13150 (inhibit_garbage_collection, Fgarbage_collect):
13151 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13152 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13153 int might not be wide enough.

13169 (Foverlay_recenter, last_overlay_modification_hooks_used)
13170 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13171 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13172 (validate_region): Omit unnecessary test for b <= e,
13173 since that's guaranteed by the previous test.
13174 (adjust_overlays_for_delete): Avoid pos + length overflow.
13175 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13176 (report_overlay_modification):
13177 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13178 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13179 Omit pointer cast, which isn't needed anyway, and doesn't work
13180 after the EMACS_INT -> ptrdiff_t change.
13181 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13182 * buffer.h: Adjust decls to match defn changes elsewhere.
13183 (struct buffer_text, struct buffer):
13184 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13185 Use EMACS_INT, not int, where int might not be wide enough.
13186 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13187 not int, to avoid needless 32-bit limit on 64-bit hosts.
13188 (exec_byte_code): Use tighter memory-full test, one that checks
13189 for alloca overflow. Don't compute the address of the object just
13190 before an array, as that's not portable. Use EMACS_INT, not
13191 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13192 * callint.c (Fcall_interactively):
13193 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13194 * callproc.c (call_process_kill, Fcall_process):
13195 Don't assume pid_t fits into an Emacs fixnum.

13204 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13205 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13206 (casify_object): Avoid integer overflow when overallocating buffer.
13207 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13208 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13209 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13210 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13211 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13212 integers are now checked earlier. All uses replaced with XINT.
13214 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13215 For CCL_MapSingle, check that content and value are in int range.

13217 Check that Vcode_version_map_vector is a vector.
13218 (resolve_symbol_ccl_program): Check that vector header is in range.
13219 Always copy the vector, so that we can check its contents reliably
13220 now rather than having to recheck each instruction as it's being
13221 executed. Check that vector words fit in 'int'.
13222 (ccl_get_compiled_code, Fregister_ccl_program)
13223 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13224 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13225 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13226 contents are in range.
13227 (Fccl_execute_on_string): Check that status is in range.
13228 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13229 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13230 Accept and return EMACS_INT, not int, because callers can pass values
13231 out of 'int' range.

13237 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13238 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13239 avoid mishandling large integers.

13248 Remove now-unnecessary CHECK_NATNUMs.
13249 (Fdefine_charset_internal): Check ranges here, more carefully.
13250 Don't rely on undefined behavior with signed left shift overflow.
13251 Don't assume unsigned int fits into fixnum, or that fixnum fits
13252 into unsigned int. Don't require max_code to be a valid fixnum;
13253 that's not true for gb10830 4-byte on a 32-bit host. Allow
13254 invalid_code to be a cons, for the same reason. Require code_offset
13255 to be a character. Avoid int overflow if max_char is close
13257 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13258 this is intended anyway and avoids some undefined behavior.
13259 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13260 INDEX_TO_CODE_POINT, as that's what it expects.
13261 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13262 * charset.h (DECODE_CHAR): Return int, not unsigned;
13263 this is what was intended anyway, and it avoids undefined behavior.
13264 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13265 integer-overflow issues.
13266 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13267 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13268 where the argument is EMACS_INT, and this behavior is not intended.
13269 * chartab.c (Fmake_char_table, Fset_char_table_range)
13270 (uniprop_get_decoder, uniprop_get_encoder):
13271 Don't assume fixnum fits in int.
13272 * cmds.c (move_point): New function, that does the gist of
13273 Fforward_char and Fbackward_char, but does so while checking
13274 for integer overflow more accurately.
13275 (Fforward_char, Fbackward_char): Use it.
13276 (Fforward_line, Fend_of_line, internal_self_insert)
13277 (internal_self_insert):
13278 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

14059 2012-05-14 Glenn Morris <rgm@gnu.org>

14066 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

14069 (report_error, report_error_1, make_hdr, copy_sym)
14070 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14071 Make arguments const char *, not char *, to avoid violations of C
14072 standard and to fix some AIX warnings reported by Gilles Pion.
14074 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14076 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14077 already have overlays loaded.
14078 (handle_single_display_spec): Before returning without displaying
14079 fringe bitmap, synchronize the bidi iterator with the main display
14080 iterator, by calling iterate_out_of_display_property.
14081 (iterate_out_of_display_property): Detect buffer iteration by
14082 testing that it->string is a Lisp string.
14083 (get_next_display_element): When the current object is exhausted,
14084 and there's something on it->stack, call set_iterator_to_next to
14085 proceed with what's on the stack, instead of returning zero.
14086 (set_iterator_to_next): If called at the end of a Lisp string,
14087 proceed to consider_string_end without incrementing string
14088 position. Don't increment display vector index past the end of
14089 the display vector. (Bug#11417)
14090 (pos_visible_p): Don't report a position visible when move_it_to
14091 stopped at the last line of window, which happens to be scanned
14092 backwards by the bidi iteration. (Bug#11464)
14094 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14096 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14097 and right-margin display specs even if the spec is invalid or we
14098 are on a TTY, and thus unable to display on the fringes.
14099 That's because the text with the property will not be displayed anyway,
14100 so we need to signal to the caller that this is a "replacing"
14101 display spec. This fixes display when the spec is invalid or we
14104 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14106 * unexaix.c (make_hdr): Fix typo in prototype.

14122 2012-05-12 Glenn Morris <rgm@gnu.org>
14124 * Makefile.in (MKDIR_P): New, set by configure.

14141 * xgselect.c (xg_select): Put maxfds+1 into a var.
14142 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14144 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14146 2012-05-10 Dave Abrahams <dave@boostpro.com>
14148 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14149 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14151 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14153 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14154 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14155 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14156 Initialize xd_registered_buses.
14158 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14160 Untag more efficiently if USE_LSB_TAG.
14161 This is based on a proposal by YAMAMOTO Mitsuharu in
14162 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14163 For an admittedly artificial (nth 8000 longlist) benchmark on
14164 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14165 Emacs's overall text size by 1%.
14166 * lisp.h (XUNTAG): New macro.
14167 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14168 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14169 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14170 * eval.c (Fautoload):
14171 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14172 * frame.h (XFRAME): Use XUNTAG.
14174 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14175 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14176 Remove unportable assumptions about print widths of types like
14178 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14179 intptr_t when converting between pointer and integer, to avoid GCC
14180 warnings about wrong width.
14182 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14184 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14185 stack for each reader_thread, instead of defaulting to 8MB
14186 determined by the linker. This avoids failures in creating
14187 subprocesses on Windows 7, see the discussion in this thread:
14188 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14190 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14192 Fix up display of the *Minibuf-0* buffer in the mini window.
14193 * keyboard.c (read_char): Don't clear the echo area if there's no
14195 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14196 contents of *Minibuf-0*) if there's no message displayed in its stead.
14198 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14200 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14203 2012-05-06 Chong Yidong <cyd@gnu.org>
14205 * lisp.mk (lisp): Update.
14207 2012-05-05 Jim Meyering <meyering@redhat.com>
14209 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14211 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14213 * data.c (PUT_ERROR): New macro.
14214 (syms_of_data): Use it. Add new error type `user-error'.
14215 * undo.c (user_error): New function.
14216 (Fprimitive_undo): Use it.
14217 * print.c (print_error_message): Adjust print style for `user-error'.
14218 * keyboard.c (user_error): New function.
14219 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14221 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14223 Do not limit current-time-string to years 1000..9999.
14224 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14225 (Fcurrent_time_string): Support any year that is supported by the
14226 underlying localtime representation. Don't use asctime, as it
14227 has undefined behavior for years outside the range -999..9999.
14229 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14231 Fix race conditions involving setenv, gmtime, localtime, asctime.
14232 Without this fix, interrupts could mess up code that uses these
14233 nonreentrant functions, since setting TZ invalidates existing
14234 tm_zone or tzname values, and since most of these functions return
14235 pointers to static storage.
14236 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14237 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14238 Grow the critical sections to include not just invoking
14239 localtime/gmtime, but also accessing these functions' results
14240 including their tm_zone values if any, and any related TZ setting.
14241 (format_time_string): Last arg is now struct tm *, not struct tm **,
14242 so that the struct tm is saved in the critical section.
14243 All callers changed. Simplify allocation of initial buffer, partly
14244 motivated by the fact that memory allocation needs to be outside
14245 the critical section.
14247 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14249 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14250 with RESET_INTERVAL.
14252 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14253 Remove duplicated buffer name initialization.
14255 2012-05-02 Jim Meyering <jim@meyering.net>
14257 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14259 * xfns.c (x_window): Use xstrdup (Bug#11375).
14261 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14263 * xdisp.c (pos_visible_p): If already at a newline from the
14264 display string before the 'while' loop, don't walk back the glyphs
14265 from it3.glyph_row. Solves assertion violation when the display
14266 string begins with a newline (egg.el). (Bug#11367)
14268 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14270 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14273 2012-05-01 Glenn Morris <rgm@gnu.org>
14275 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14276 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14277 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14278 All were removed before 23.1.
14280 * dispnew.c: Remove HAVE_LIBNCURSES test;
14281 it is always true on relevant platforms.
14283 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14284 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14286 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14288 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14290 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14291 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14294 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14296 Do not avoid creating empty evaporating overlays (Bug#9642).
14297 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14298 That is, do not delete an evaporating overlay if it becomes
14299 empty after its bounds are adjusted to fit within its buffer.
14300 This fix caused other problems, and I'm reverting it until we get
14301 to the bottom of them.
14303 2012-04-27 Chong Yidong <cyd@gnu.org>
14305 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14307 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14309 * xdisp.c (pos_visible_p): If the window start position is beyond
14310 ZV, start the display from buffer beginning. Prevents assertion
14311 violation in init_iterator when the minibuffer window is scrolled
14312 via the scroll bar.
14314 * window.c (window_scroll_pixel_based): Likewise.
14316 2012-04-27 Chong Yidong <cyd@gnu.org>
14318 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14320 2012-04-27 Glenn Morris <rgm@gnu.org>
14322 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14323 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14325 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14327 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14328 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14330 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14332 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14333 display element, check also the underlying string or buffer
14334 character. (Bug#11341)
14336 * w32menu.c: Include w32heap.h.
14337 (add_menu_item): If the call to AppendMenuW (via
14338 unicode_append_menu) fails, disable Unicode menus only if we are
14339 running on Windows 9X/Me.
14341 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14343 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14344 (xgetint): Add missing shift for LSB tags.
14346 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14348 * keyboard.c (read_char): Don't wipe echo area for select window
14349 events: These might get delayed via `mouse-autoselect-window'
14352 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14354 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14355 manipulation of :loaded-from data.
14357 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14359 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14360 now a cons (bug#11311).
14362 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14364 Do not create empty overlays with the evaporate property (Bug#9642).
14365 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14366 if it becomes empty after its bounds are adjusted to fit within
14367 its buffer. Without this fix, in a nonempty buffer (let ((o
14368 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14369 yields an empty overlay that has the evaporate property, which is
14370 not supposed to happen.
14372 Fix minor GTK3 problems found by static checking.
14373 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14374 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14375 (struct _EmacsFixedClass, emacs_fixed_get_type):
14376 Move decls here from emacsgtkfixed.h, since they needn't be public.
14377 (emacs_fixed_get_type): Now static.
14378 (emacs_fixed_class_init): Omit unused local.
14379 (emacs_fixed_child_type): Remove; unused.
14380 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14381 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14382 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14383 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14384 (EMACS_FIXED_GET_CLASS): Remove; unused.
14385 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14387 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14388 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14390 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14392 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14393 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14394 (__malloc_size_t, __malloc_ptrdiff_t):
14395 Remove. All uses removed, replaced by the definiens if needed,
14396 since we can assume C89 or better now.
14397 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
14398 (protect_malloc_state, align, get_contiguous_space)
14399 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
14400 (malloc_atfork_handler_child, malloc_enable_thread)

14404 (special_realloc, _realloc_internal_nolock, _realloc_internal)
14405 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14406 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14407 Define using prototypes, not old style.
14408 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14409 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14410 (align): Don't assume that signed integer overflow wraps around.
14411 Omit unused local var.
14412 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

14414 Omit no-longer-needed casts.
14415 (valloc): Use getpagesize, not __getpagesize.
14416 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14417 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14419 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14421 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14423 Move functions from C to Lisp. Make non-blocking method calls
14424 the default. Implement further D-Bus standard interfaces.

14454 (Fdbus_method_return_internal, Fdbus_method_error_internal)
14455 (Fdbus_send_signal, Fdbus_register_service)
14456 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

14469 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
14470 Do not assume ptrdiff_t is the same width as 'int'.
14472 * alloc.c: Handle unusual debugging option combinations.
14473 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14474 since the two debugging options are incompatible.
14475 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14477 (mem_init, mem_insert, mem_insert_fixup):
14478 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

14488 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14489 Use Emacs indenting style more consistently. Avoid some casts.
14490 Use 'double' consistently rather than mixing 'float' and 'double'.
14492 2012-04-21 Eduard Wiebe <usenet@pusto.de>
14494 * sysdep.c (list_system_processes, system_process_attributes):

14504 It is never used otherwise.
14506 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
14508 * print.c (print_preprocess): Only check print_depth if print-circle
14510 (print_object): Check for cycles even when print-circle is nil and

14513 2012-04-20 Chong Yidong <cyd@gnu.org>
14515 * process.c (wait_reading_process_output): If EIO occurs on a pty,

14526 * xdisp.c (string_buffer_position_lim): Limit starting position to
14528 (set_cursor_from_row): If called for a mode-line or header-line
14529 row, return zero immediately.
14530 (try_cursor_movement): If inside continuation line, don't back up
14531 farther than the first row after the header line, if any.
14532 Don't consider the header-line row as "partially visible", even if
14533 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14535 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14551 the Emacs and Gnulib regex code is merged.
14552 (xmalloc, xrealloc): Now static.

14569 Fix minor alloc.c problems found by static checking.
14570 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
14571 New extern decls, to avoid calling undeclared functions.
14572 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14573 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14574 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14575 (NEED_MEM_INSERT): New macro.
14576 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14577 Remove one incorrect comment and fix another.

14591 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14592 Remove decls. This fixes an "It stinks!".
14594 * alloc.c (which_symbols): Fix alignment issue / type clash.
14596 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14598 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14599 (struct Lisp_Misc_Any): Likewise.
14600 (struct Lisp_Free): Likewise.
14601 * alloc.c (union aligned_Lisp_Symbol): Define.

14611 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14612 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14613 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14614 * s/netbsd.h, s/sol2-6.h:
14615 Remove definition of GC_MARK_STACK, since the default now works.
14616 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14617 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14618 no longer the default.
14619 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14621 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14623 * lread.c (lisp_file_lexically_bound_p):
14624 Fix hang at ";-*-\n" (bug#11238).
14626 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14628 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

14640 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14642 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14644 2012-04-11 Daniel Colascione <dancol@dancol.org>
14646 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14647 against is gone. It's better to use vfork now so that when Cygwin
14648 gains a new, working vfork, we use it automatically (bug#10398).
14650 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14668 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14670 * w32.c (w32_delayed_load): Record the full path of the library
14671 being loaded (bug#10424).
14673 2012-04-09 Glenn Morris <rgm@gnu.org>
14675 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14676 not just in the obarray, before snarfing them. (Bug#11036)
14678 * Makefile.in ($(leimdir)/leim-list.el):
14679 Pass EMACS rather than BUILT_EMACS.
14681 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14683 * process.c (make_process):
14684 * process.h: Add integer `gnutls_handshakes_tried' member to

14693 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14694 attempts per process (connection).
14696 2012-04-09 Chong Yidong <cyd@gnu.org>
14698 * eval.c (Fuser_variable_p, user_variable_p_eh)
14699 (lisp_indirect_variable): Functions deleted.
14700 (Fdefvar): Caller changed.
14702 * callint.c (Finteractive, Fcall_interactively):
14703 * minibuf.c (Fread_variable): Callers changed.
14705 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14707 * xdisp.c (set_cursor_from_row): If the display string appears in
14708 the buffer at position that is closer to point than the position
14709 after the display string, display the cursor on the first glyph of
14710 the display string. Fixes cursor display when a 'display' text
14711 property immediately follows invisible text. (Bug#11094)
14713 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14715 composite.c: use 'double' consistently
14716 * composite.c (get_composition_id): Use 'double' consistently
14717 instead of converting 'float' to 'double' and vice versa; this is
14718 easier to understand and avoids a GCC warning.
14720 2012-04-09 Glenn Morris <rgm@gnu.org>
14722 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14723 preparation for dumping it with emacs. (Bug#4789)
14724 (leimdir): New variable.

14744 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14745 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14746 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14747 objects, as mark_maybe_pointer will catch them otherwise.

14760 * makefile.w32-in (OBJ2): Add xml.$(O).
14761 (GLOBAL_SOURCES): Add xml.c.
14762 ($(BLD)/xml.$(O)): New dependency list.
14764 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14765 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14766 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14767 [!WINDOWSNT]: New macros.
14768 (init_libxml2_functions, libxml2_loaded_p): New functions.
14769 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14770 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14771 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14772 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14774 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14775 Call init_libxml2_functions before calling libxml2 functions.
14776 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14778 * emacs.c: Don't include libxml/parser.h.
14779 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14780 xmlCleanupParser directly.
14782 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14784 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14786 * indent.c (Fvertical_motion): If there is a display string at
14787 point, use it.vpos to compute how many lines to backtrack after
14788 move_it_to point. (Bug#11133)
14790 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14792 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14793 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14794 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14795 macros related to unification of CJK characters. For the details,
14796 see the discussion following the message here:
14797 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14799 2012-04-04 Chong Yidong <cyd@gnu.org>
14801 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14803 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14805 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14813 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14815 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14816 position we get to after a call to move_it_to fails the
14817 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14818 only if we wind up in a string from display property. (Bug#11063)
14820 * window.c (Fdelete_other_windows_internal): Invalidate the row
14821 and column information about mouse highlight, so that redisplay
14822 restores it after reallocating the glyph matrices. (Bug#7464)
14824 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14825 string comes from a `display' text property, use the buffer
14826 position of that property as if we actually saw that position in
14828 (move_it_by_lines): Remove the assertion that
14829 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14830 violated when there's a before-string at the beginning of a line.
14833 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14835 * xdisp.c (append_space_for_newline): If the default face was

14837 (extend_face_to_end_of_line): Use the remapped default face for
14838 extending the face to the end of the line.
14839 (display_line): Call extend_face_to_end_of_line when the default
14840 face was remapped. (Bug#11068)
14842 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14844 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

14862 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14863 (command_loop_1): Use it; inhibit selection update for

14868 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14870 2012-03-25 Kenichi Handa <handa@m17n.org>
14872 * dispextern.h (struct glyph): Change the bit length of
14873 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14875 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14877 * s/ms-w32.h (tzname): Include time.h before redirecting to

14882 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14885 * xterm.c (XTread_socket): Only modify handling_signal if
14886 !SYNC_INPUT. (Bug#11080)
14888 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14890 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14891 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14892 when fetching a multibyte character consumes more bytes than
14893 CHAR_BYTES returns, due to unification of CJK characters in
14894 string_char. (Bug#11073)
14896 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14898 * process.c (wait_reading_process_output): Handle pty disconnect
14899 by refraining from sending oneself a SIGCHLD (bug#10933).
14901 2012-03-22 Chong Yidong <cyd@gnu.org>
14903 * dispextern.h (struct it): New member string_from_prefix_prop_p.

14933 that is not from display property, accept the row as a "cursor
14934 row" if one of the string's character has a non-nil `cursor'
14935 property. Fixes cursor positioning when there are newlines in
14936 overlay strings, e.g. in icomplete.el. (Bug#11035)
14938 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14940 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14942 2012-03-12 Chong Yidong <cyd@gnu.org>
14944 * eval.c (inhibit_lisp_code): Rename from
14945 inhibit_window_configuration_change_hook; move from window.c.
14947 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14948 * window.c (run_window_configuration_change_hook)
14949 (syms_of_window): Callers changed.
14951 2012-03-11 Chong Yidong <cyd@gnu.org>

14957 2012-03-10 Chong Yidong <cyd@gnu.org>
14959 * frame.c (other_visible_frames): Don't assume the selected frame
14960 is visible (Bug#10955).
14962 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14964 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14966 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14968 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14969 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14972 2012-03-03 Glenn Morris <rgm@gnu.org>
14974 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14976 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14979 position past the first glyph_row that ends at ZV. (Bug#10902)
14980 (redisplay_window, next_element_from_string): Fix typos in
14982 (redisplay_window): Pass to move_it_vertically the margin in
14983 pixels, not in screen lines.
14985 2012-03-02 Glenn Morris <rgm@gnu.org>
14987 * buffer.c (buffer-list-update-hook): Doc fix.
14989 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14991 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14992 push_it before setting up the iterator for the first overlay
14993 string, even if we have an empty string loaded.
14994 (next_overlay_string): If there's an empty string on the iterator
14995 stack, pop the stack. (Bug#10903)
14997 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14999 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15000 Suggested by Stefan Monnier in
15001 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15002 * alloc.c (widen_to_Lisp_Object): New static function.
15003 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15004 and widening them to Lisp_Objects. This would work even if
15005 USE_LSB_TAG is defined and wide integers are used, which might
15006 happen in a future version of Emacs.
15008 2012-02-25 Chong Yidong <cyd@gnu.org>
15010 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
15013 * xselect.c (Fx_selection_exists_p): Doc fix.

15046 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
15047 when computing $valmask.
15049 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15050 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15051 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15052 It's useless in that case, and it can cause problems on hosts
15053 that allocate halves of EMACS_INT values separately.
15054 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15055 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15056 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15057 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15058 it avoids undefined behavior on hosts where shifting right by more
15059 than the word width has undefined behavior.
15061 2012-02-19 Chong Yidong <cyd@gnu.org>
15063 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15064 (Funhandled_file_name_directory, Ffile_name_as_directory)

15185 * character.c (char_width): Return EMACS_INT, not int.
15186 (char_width, c_string_width): Check for overflow when

15213 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

15220 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15221 first 2 arguments are identical. This makes inserting large
15222 output from a subprocess an order of magnitude faster on

15861 behave as if the cursor position were at the window margin.
15863 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15864 and the cursor position is out of bounds, behave as if the cursor
15865 position were at the window margin. (Bug#10075)
15867 2011-11-18 Chong Yidong <cyd@gnu.org>

15891 compute_line_metrics.
15892 (compute_line_metrics): Call row_hash, instead of computing the
15895 * dispnew.c (verify_row_hash): Call row_hash for computing the
15896 hash code of a row, instead of duplicating code from xdisp.c.
15898 * dispextern.h (row_hash): Add prototype.
15900 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

16003 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
16005 Avoid some portability problems by eschewing 'extern inline' functions.
16006 The trivial performance wins aren't worth the portability hassles; see
16007 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
16009 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

16049 (delete_all_subwindows): Rename to delete_all_child_windows.
16050 (Fdelete_other_windows_internal, Fset_window_configuration):
16051 Call delete_all_child_windows instead of delete_all_subwindows.
16052 * frame.c (delete_frame): Call delete_all_child_windows instead

16055 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
16057 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
16058 This is also needed for porting to any host where GC_MARK_STACK is
16059 not GC_MAKE_GCPROS_NOOPS.
16060 (which_symbols): Use it.
16062 2011-11-07 Kenichi Handa <handa@m17n.org>
16064 * coding.c (coding_set_destination): Check coding->src_pos only

16075 * xmenu.c (cleanup_widget_value_tree): New function.
16076 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
16077 calling free_menubar_widget_value_tree directly (Bug#9830).
16079 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
16081 Fix some portability problems with 'inline'.

16083 (window_box_width, window_box_left, window_box_left_offset)
16084 (window_box_right, window_box_right_offset): Declare extern.
16085 Otherwise, these inline functions do not conform to C99 and
16086 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16087 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16088 * intervals.c (adjust_intervals_for_insertion)
16089 (adjust_intervals_for_deletion): Now extern, because otherwise the

16091 (static_offset_intervals): Remove.
16092 (offset_intervals): Rewrite using the old contents of
16093 static_offset_intervals. The old version didn't conform to C99
16094 because an extern inline function contained a reference to an
16095 identifier with static linkage.
16097 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
16099 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

16117 (Fwindow_vscroll): Doc fix.
16118 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
16119 argument, since it makes no sense to pass a live window and for
16120 consistency with window-child.

16148 (unwind_create_frame): New function (Bug#9943).
16149 (Fx_create_frame): Restructure code to be more similar to the one in
16150 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

16161 official. Move initialization of image_cache_refcount and
16162 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

16330 (w32font_open_internal, compute_metrics):
16331 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16332 instead of calling the "wide" APIs directly.

16407 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16408 * editfns.c: Rewrite current-time-zone so that it invokes
16409 the equivalent of (format-time-string "%Z") to get the time zone name.
16410 This fixes a bug when the time zone name contains characters that
16411 need converting from the system time locale to Emacs internal format.
16412 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16413 that patch fixed format-time-string to do the conversion, but
16414 I forgot to fix current-time-zone.
16415 (format_time_string): New function, containing most of
16416 what Fformat_time_string used to contain.
16417 (Fformat_time_string): Rewrite in terms of format_time_string.
16418 This doesn't change this function's behavior.
16419 (current-time-zone): Rewrite to use format_time_string.
16420 This fixes the bug reported by Michael Schierl in
16421 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16422 Jason Rumney's 2007-06-07 change worked around this bug, but
16424 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16426 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16428 * xdisp.c (start_display): If the character at POS is displayed
16429 via a display vector, reset IT->current.dpvec_index to zero.
16430 (try_window_reusing_current_matrix): If a line ends in a display
16431 vector or the next line starts in a display vector, continue
16432 redrawing the window even though the character position of
16433 start_row was reached.
16436 2011-10-18 Chong Yidong <cyd@gnu.org>
16438 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16439 with nobreak-char-display too.
16441 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16443 Fix part 3 of bug#9771.
16444 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16445 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16446 non-neutral characters if the current character is a paragraph
16447 separator (a.k.a. Newline). This avoids running the same
16448 expensive loop twice, once when we consume the preceding newline
16449 and the other time when the line actually needs to be displayed.
16450 Avoid the loop when we see neutrals on the base embedding level
16451 following a character whose directionality is the same as the
16452 paragraph's. This avoids running the expensive loop when a line
16453 ends in a long sequence of neutrals, like control characters.
16454 Add assertion against STRONG_AL type. Slightly rearrange code
16455 that determines the type of a neutral given the first non-neutral
16457 (bidi_level_of_next_char): Set next_en_pos to zero when
16458 invalidating its info.
16460 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16462 * xdisp.c (push_display_prop): Determine whether to record string
16463 or buffer position by IT->string, not by IT->method. Allow
16464 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16465 (move_it_vertically_backward): Don't look for character position
16466 immediately after the newline when in a continuation line.
16469 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16471 * window.c (coordinates_in_window): Rewrite and delabelize
16472 vertical border check. (Bug#5357) (Bug#9618)
16474 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16476 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16477 errors in XSetWindowBorder (bug#9310).
16479 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16481 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16482 avoid crash when xmalloc overrun checking is enabled.
16484 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16486 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16487 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16488 cursor motion with <left> and <right> arrow keys.
16490 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16491 some callers set that themselves.
16493 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16495 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16496 display string and the previous row comes from the same string and
16497 is empty. (Bug#9739) (Bug#9738)
16499 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16501 * doc.c (get_doc_string): Encode file name (bug#9735).
16503 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16505 * bidi.c (bidi_level_of_next_char):
16506 * xdisp.c (get_visually_first_element): Remove old incorrect
16507 comments regarding the Unicode Line Separator character.
16509 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16511 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16513 * alloc.c (Fgc_status): Do not access beyond zombies array
16514 boundary if nzombies > MAX_ZOMBIES.
16515 * alloc.c (dump_zombies): Add missing format specifier.
16517 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16519 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16520 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16522 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16523 Some packages use them to denote characters with modifiers.
16525 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16527 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16528 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16529 matching a pp-number. Rename parameter var to var1.
16531 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16533 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16535 2011-10-08 Glenn Morris <rgm@gnu.org>
16537 * callint.c (Fcall_interactively): Give a more explicit error for the
16538 'c' case with a non-character input. (Bug#8479)
16540 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16542 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16544 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16545 lines that are hscrolled on the left.
16547 * dispnew.c (buffer_posn_from_coords): Account for a possible
16548 presence of header-line. (Bug#4426)
16550 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16552 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16553 Don't advertise functionality which we discourage or doesn't work.
16555 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16557 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16558 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16559 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16560 this makes Emacs dump core during garbage collection on rare
16561 occasions. sizeof is obviously inferior to offsetof here, so
16562 stick with offsetof.
16563 (GC_POINTER_ALIGNMENT): New macro.
16564 (mark_memory): Omit 3rd (offset) arg; caller changed.
16565 Don't assume EMACS_INT alignment is the same as pointer alignment.
16567 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16569 * keyboard.c (read_key_sequence_remapped): New var.
16570 (read_key_sequence): Compute remapping in the right buffer.
16571 (command_loop_1): Use read_key_sequence's remapping directly.
16573 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16575 * dired.c (file_name_completion): Don't expand file name.
16576 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16577 before checking file name handler.
16579 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16580 they've been requested explicitly (bug#9591).
16582 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16584 * keymap.c (Fsingle_key_description): Use make_specified_string
16585 instead of build_string to build string from push_key_description.
16588 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16590 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16591 This fixes a Y2038 bug on 64-bit hosts.
16592 * buffer.c (reset_buffer):
16593 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16594 (Fclear_buffer_auto_save_failure):
16595 Use 0, not -1, to represent an unset failure time, since time_t
16596 might not be signed.
16598 Remove dependency on glibc malloc internals.
16599 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16600 Move back here from lisp.h, but with their new implementations.
16601 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16602 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16603 * charset.c (charset_table_init): New static var.
16604 (syms_of_charset): Use it instead of xmalloc. This removes a
16605 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16606 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16607 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16608 Move back to alloc.c.
16609 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16610 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16612 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16614 * nsterm.m (windowDidResize): Call x_set_window_size only when
16615 ns_in_resize is true. Otherwise set pixelwidth/height and
16616 call change_frame_size (Bug#9628).
16618 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16620 Port --enable-checking=all to Fedora 14 x86-64.
16621 * charset.c (syms_of_charset): Also account for glibc malloc's
16622 internal overhead when calculating the initial malloc maximum.
16624 Port --enable-checking=all to Fedora 14 x86.
16625 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16627 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16628 (overrun_check_realloc, overrun_check_free):
16629 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16630 That way, xmalloc returns a properly-aligned pointer even if
16631 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16632 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16633 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16634 into account when calculating the initial malloc maximum.
16635 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16636 Move here from alloc.c, so that charset.c can use it too.
16637 Properly align; the old code wasn't right for common 32-bit hosts
16638 when configured with --enable-checking=all.
16639 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16640 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16642 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16644 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16647 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16649 * xdisp.c (compute_display_string_end): If there's no display
16650 string at CHARPOS, return -1.
16652 * bidi.c (bidi_fetch_char): When compute_display_string_end
16653 returns a negative value, treat the character as a normal
16654 character not covered by a display string. (Bug#9624)
16656 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16658 * lread.c (Fread_from_string): Fix typo in docstring.
16660 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16662 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16663 newline, reseat the iterator instead of bidi-iterating there one
16664 character at a time. (Bug#9610)
16665 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16666 TO_CHARPOS if the bidi iterator is at base embedding level.
16668 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16670 * lread.c (readevalloop): Use correct code for NBSP.
16671 (read1): Likewise. (Bug#9608)
16673 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16675 * dbusbind.c (Fdbus_register_signal): When service is not
16676 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16678 2011-09-25 Glenn Morris <rgm@gnu.org>
16680 * buffer.c (truncate-lines): Doc fix.
16682 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16684 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16685 (Fset_window_next_buffers): Doc fix.
16687 2011-09-24 Glenn Morris <rgm@gnu.org>
16689 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16691 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16693 Fix minor problems found by static checking.
16694 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16695 * indent.c (Fvertical_motion): Fix == vs = typo.
16697 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16699 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16700 Default value is now t. Doc fix.
16702 * indent.c (Fvertical_motion): Compute and apply the overshoot
16703 logic when moving up, not only when moving down. Fix the
16704 confusing name and values of the it_overshoot_expected variable;
16705 logic changes accordingly. (Bug#9254) (Bug#9549)
16707 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16708 CHARPOS is covered by a display string which includes newlines.
16709 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16710 is covered by a display string with embedded newlines.
16712 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16714 * dbusbind.c (Fdbus_register_signal): Add match rule to
16715 Vdbus_registered_objects_table. (Bug#9581)
16716 (Fdbus_register_method, Vdbus_registered_objects_table):
16719 2011-09-24 Jim Meyering <meyering@redhat.com>
16721 do not ignore write error for any output size
16722 The previous change was incomplete.
16723 While it makes emacs --batch detect the vast majority of stdout
16724 write failures, errors were still ignored whenever the output size is
16725 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16726 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16727 && echo FAIL: ignored write error
16728 FAIL: ignored write error
16729 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16730 && echo FAIL: ignored write error
16731 FAIL: ignored write error
16732 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16734 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16736 * emacs.c (Fkill_emacs): In noninteractive mode exit
16737 non-successfully if a write error occurred on stdout. (Bug#9574)
16739 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16741 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16744 * dispextern.h (struct it): Update the comment documenting what
16747 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16749 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16750 a display string, extend search for cursor position to end of row.
16751 (find_row_edges): If the row ends in a newline from a display
16752 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16753 Handle the case of a display string with multiple newlines.
16754 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16755 non-empty line. Fixes confusing cursor motion with arrow keys at
16756 the beginning of a line that starts with whitespace.
16758 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16760 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16763 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16765 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16766 boolean (Bug#9154).
16768 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16770 * xdisp.c (display_line): Record maximum and minimum buffer
16771 positions even if no glyphs were produced (e.g., by a zero-width
16772 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16773 buffer positions that will be removed from the glyph row because
16775 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16776 column is beyond frame width: don't subtract 1 "pixel" when
16777 computing width of the stretch.
16778 (reseat_at_next_visible_line_start): Undo the change made on
16779 2011-09-17 that saved paragraph information and restored it after
16780 the call to `reseat'. (Bug#9545)
16782 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16784 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16785 and turn window cursor on if cleared (Bug#9415).
16787 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16789 * search.c (boyer_moore): Take unibyte characters from pattern
16790 literally. (Bug#9458)
16792 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16794 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16796 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16798 Fix minor problem found by static checking.
16799 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16800 initialized, to pacify gcc -Wuninitialized.
16802 * fileio.c: Report proper errno when syscall falls.
16803 (Finsert_file_contents): Save and restore errno,
16804 so that report_file_error outputs the correct diagnostic.
16805 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16807 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16809 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16811 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16813 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16814 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16816 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16818 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16819 about the current paragraph and restore it after the call to reseat.
16821 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16822 (bidi_find_paragraph_start): Search back for paragraph beginning
16823 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16824 (bidi_move_to_visually_next): Only trigger paragraph-related
16825 computations when the last character is a newline or at EOB, not
16826 just any NEUTRAL_B. (Bug#9470)
16828 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16829 truncated lines if point is covered by a display string. (Bug#9524)
16831 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16833 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16834 (cons_to_x_long): New function.
16835 (lisp_data_to_selection_data): Use it. Correct the test for
16836 short-versus-long data; it was negated. Break out of vector
16837 loop, for efficiency, when a long datum is discovered.
16839 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16841 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16843 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16845 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

16861 * term.c (encode_terminal_code):
16862 * composite.c (composition_update_it, get_composition_id):
16863 * xdisp.c (get_next_display_element)
16864 (fill_composite_glyph_string): Add comments about special meaning
16865 of TAB characters in a composition.
16867 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16869 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16870 This occurs when processing a multibyte format.
16871 Problem reported by Wolfgang Jenker.
16873 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16875 * xdisp.c (try_cursor_movement): Only check for exact match if
16876 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16878 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16880 Remove unused external symbols.
16881 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16882 * xdisp.c (calc_pixel_width_or_height): Now static.
16883 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

16885 * w32term.c: Fix comment to match code.
16886 * xterm.c, xterm.h (x_catching_errors): Remove.
16888 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16890 * xselect.c: Use signed conversions more consistently (Bug#9498).
16891 (selection_data_to_lisp_data): Assume incoming selection data are
16892 signed integers, not unsigned. This is to be consistent with
16893 outgoing selection data, which was modified to use signed integers
16894 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16895 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16896 expects long, not unsigned long.
16898 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16900 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16901 computation of loop end. Reported by Johan Bockgård
16904 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16906 * frame.c (Fother_visible_frames_p): Function deleted.
16908 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16910 * indent.c (compute_motion): Process display vector front to back
16911 rather than the other way around. (Bug#2496)
16913 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16915 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16917 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16919 * minibuf.c (Fread_from_minibuffer): Doc fix.
16921 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16923 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16924 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16926 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16928 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16929 value for non-existent files.
16931 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16933 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16934 set its "size" to -1. This will set the modtime_size field of
16935 the corresponding buffer to -1, which is what
16936 verify-visited-file-modtime expects for files that do not exist.
16939 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16941 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16943 * lisp.h: ... from here. push_key_description is no longer
16944 defined in keyboard.c, so its declaration should not be in
16945 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16946 logically belongs with push_key_description.
16948 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16950 * buffer.h: Include <sys/types.h> instead of <time.h>.
16951 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16952 Problem reported by Herbert J. Skuhra.
16954 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16956 * xml.c (parse_region): Make the parsing work for
16957 non-comment-starting XML files again (bug#9144).
16959 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16961 * image.c (gif_load): Fix calculation of bottom and right corner.
16964 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16966 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16967 redisplay in small windows.
16969 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16971 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16973 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16975 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16976 Operate on live windows only.
16978 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16980 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16982 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16984 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16985 only under bidi iteration.
16987 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16989 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16991 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16993 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16994 Without this fix, the command to link temacs failed due to an
16995 undefined symbol __builtin_isnan. This is because
16996 /usr/include/iso/math_c99.h #defines isnan(x) to
16997 __builtin_isnan(x), but the bundled gcc, which identifies itself
16998 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17000 * floatfns.c (isnan): #undef, and then #define to a clone of
17002 (Fisnan): Always define, since it's always available now.
17003 (syms_of_floatfns): Always define isnan at the Lisp level.
17005 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17007 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17009 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17011 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17012 The previous code assumed that file offsets (off_t values) fit in
17013 EMACS_INT variables, which is not true on typical 32-bit hosts.
17014 The code messed up by falsely reporting buffer overflow in cases
17015 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17016 when "big" contains more than 2**29 bytes, even though this
17017 inserts just one byte and does not overflow the buffer.
17018 (Finsert_file_contents): Store file offsets as off_t
17019 values, not as EMACS_INT values. Check for overflow when
17020 converting between EMACS_INT and off_t. When checking for
17021 buffer overflow or for overlap, take the offsets into account.
17022 Don't use EMACS_INT for small values where int suffices.
17023 When checking for overlap, fix a typo: ZV was used where
17024 ZV_BYTE was intended.
17025 (Fwrite_region): Don't assume off_t fits into 'long'.
17026 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17028 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17030 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17032 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17034 sprintf-related integer and memory overflow issues (Bug#9412).
17036 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17037 (esprintf, exprintf, evxprintf): New functions.
17038 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17039 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17040 (modify_event_symbol): Do not assume that the length of
17041 name_alist_or_stem is safe to alloca and fits in int.
17042 (Fexecute_extended_command): Likewise for function name and binding.
17043 (Frecursion_depth): Wrap around reliably on integer overflow.
17044 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17045 since some callers pass EMACS_INT values.
17046 (Fsingle_key_description): Don't crash if symbol name contains more
17047 than MAX_ALLOCA bytes.
17048 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17049 (get_minibuffer): Arg is now EMACS_INT, not int.
17050 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17051 (esprintf, exprintf, evxprintf): New decls.
17052 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17054 * dbusbind.c (signature_cat): New function.
17055 (xd_signature, Fdbus_register_signal):
17056 Do not overrun buffer; instead, report string overflow.
17058 * dispnew.c (add_window_display_history): Don't overrun buffer.
17059 Truncate instead; this is OK since it's just a log.
17061 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17062 even if the time zone offset is outlandishly large.
17063 Don't mishandle offset == INT_MIN.
17065 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17066 when creating daemon; the previous buffer-overflow check was incorrect.
17068 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17069 which has the guts of the old verror function.
17071 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17072 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17074 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17075 (font_unparse_xlfd): Don't blindly alloca long strings.
17076 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17077 fits in int, when using sprintf. Use single snprintf to count
17078 length of string rather than counting it via multiple sprintfs;
17079 that's simpler and more reliable.
17080 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17081 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17082 sprintf, in case result does not fit in int.
17084 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17085 (fontset_from_font): Print it.
17087 * frame.c (tty_frame_count): Now printmax_t, not int.
17088 (make_terminal_frame, set_term_frame_name): Print it.
17089 (x_report_frame_params): In X, window IDs are unsigned long,
17090 not signed long, so print them as unsigned.
17091 (validate_x_resource_name): Check for implausibly long names,
17092 and don't assume name length fits in 'int'.
17093 (x_get_resource_string): Don't blindly alloca invocation name;
17094 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17097 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17098 (xg_check_special_colors, xg_set_geometry):
17099 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17101 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17102 Use esprintf, not sprintf, in case result does not fit in int.
17104 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17105 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17106 it as a large positive number.
17107 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17108 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17110 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17111 in case result does not fit in int.
17113 * print.c (float_to_string): Detect width overflow more reliably.
17114 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17115 buffer overrun. Don't assume list length fits in 'int'. Treat
17116 print length of 0 as 0, not as infinity; to be consistent with other
17117 uses of print length in this function. Don't overflow print length
17118 index. Don't assume hash table size fits in 'long', or that
17119 vectorlike size fits in 'unsigned long'.
17121 * process.c (make_process): Use printmax_t, not int, to format
17122 process-name gensyms.
17124 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17126 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17127 to avoid potential buffer overrun.
17129 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17130 if X resource line is longer than 512 bytes.
17132 * xfns.c (x_window): Make sprintf buffer a bit bigger
17133 to avoid potential buffer overrun.
17135 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17137 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17139 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17141 Integer overflow fixes for scrolling, etc.
17142 Without these, Emacs silently mishandles large integers sometimes.
17143 For example, "C-u 4294967297 M-x recenter" was treated as if
17144 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17146 * xdisp.c (try_window_id): Check Emacs fixnum range before
17147 converting to 'int'.
17149 * window.c (window_scroll_line_based, Frecenter):
17150 Check that an Emacs fixnum is in range before assigning it to 'int'.
17151 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17152 values converted from Emacs fixnums.
17153 (Frecenter): Don't wrap around a line count if it is out of 'int'
17154 range; instead, treat it as an extreme value.
17155 (Fset_window_configuration, compare_window_configurations):
17156 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17158 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17159 that can exceed INT_MAX. Check that EMACS_INT value is in range
17160 before assigning it to the (possibly-narrower) index.
17161 (match_limit): Don't assume that a fixnum can fit in 'int'.
17163 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17166 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17167 (Fvertical_motion): Don't wrap around LINES values that don't fit
17168 in 'int'. Instead, treat them as extreme values. This is good
17169 enough for windows, which can't have more than INT_MAX lines anyway.
17171 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17173 * Require libxml/parser.h to avoid compilation warning.
17175 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17177 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17178 since this reportedly can destroy thread storage.
17180 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17182 * syntax.c (find_defun_start): Update all cache variables if
17183 exiting early (Bug#9401).
17185 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17187 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17189 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17190 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17191 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17193 * term.c (tty_append_glyph): New function.
17194 (produce_stretch_glyph): Static function and its prototype deleted.
17196 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17199 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17201 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17202 when checking :margin (Bug#9390).
17203 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17204 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17205 so that the name doesn't mislead. All uses changed.
17207 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17209 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17212 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17214 * xdisp.c (move_it_to): Don't bail out early when reaching
17215 position beyond to_charpos, if we are scanning backwards.
17216 (move_it_vertically_backward): When DY == 0, make sure we get to
17217 the first character in the line after the newline.
17219 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17221 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17222 (ccl_driver): Do not generate an out-of-range pointer.
17223 (Fccl_execute_on_string): Remove unnecessary check for
17224 integer overflow, noted by Stefan Monnier in
17225 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17226 Remove a FIXME that didn't need fixing.
17227 Simplify the newly-introduced buffer reallocation code.
17229 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17231 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17233 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17235 Integer and memory overflow issues (Bug#9196).
17237 * doc.c (get_doc_string): Rework so that
17238 get_doc_string_buffer_size is the actual buffer size, rather than
17239 being 1 less than the actual buffer size; this makes xpalloc more
17242 * image.c (x_allocate_bitmap_record, cache_image):
17243 * xselect.c (Fx_register_dnd_atom):
17244 Simplify previous changes by using xpalloc.
17246 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17247 since either will do and ptrdiff_t is convenient with xpalloc.
17249 * charset.c (charset_table_size)
17250 (struct charset_sort_data.priority): Now ptrdiff_t.
17251 (charset_compare): Don't overflow if priorities differ greatly.
17252 (Fsort_charsets): Don't assume list length fits in int.
17253 Check for size-calculation overflow when allocating sort data.
17254 (syms_of_charset): Allocate an initial charset table that is
17255 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17257 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17259 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17260 The actual value is always <= INT_MAX, and leaving it unsigned made
17261 overflow checking harder.
17263 * dispextern.h (struct glyph_matrix.rows_allocated)
17264 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17265 with xpalloc. The values are still always <= INT_MAX.
17267 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17269 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17270 (SAFE_NALLOCA): New macro.
17272 * region-cache.c (struct boundary.pos, find_cache_boundary)
17273 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17274 (set_cache_region, invalidate_region_cache)
17275 (revalidate_region_cache, know_region_cache, region_cache_forward)
17276 (region_cache_backward, pp_cache):
17277 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17278 so that ptrdiff_t * can be passed to xpalloc.
17279 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17280 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17281 (pp_cache): Don't assume cache_len fits in int.
17282 * region-cache.h: Adjust extern decls to match.
17284 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17285 EMACS_INT, since either will do, for xpalloc.
17287 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17288 (xnmalloc, xnrealloc, xpalloc): New functions.
17290 * bidi.c (bidi_shelve_header_size): New constant.
17291 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17292 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17294 * bidi.c (bidi_cache_shrink):
17295 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17297 Don't update size of array until after memory allocation succeeds,
17298 because xmalloc/xrealloc may not return.
17299 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17300 now that we have proper integer overflow checking.
17301 (record_overlay_string, overlay_strings): Catch overflows when
17302 calculating size of overlay_str_buf.
17304 * callproc.c (Fcall_process): Check for size overflow when
17305 calculating size of args2.
17306 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17307 Normally we prefer signed values, but sticking with ptrdiff_t would
17308 require adding more-complicated checks.
17310 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17311 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17312 Redo buffer-overflow calculations to avoid integer overflow.
17313 Add a FIXME comment where memory seems to be over-allocated.
17315 * character.c (Fstring): Check for size-calculation overflow.
17317 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17318 unnecessary integer overflow. Check for size overflow.
17319 (encode_coding_object): Don't update size until xmalloc succeeds.
17321 * composite.c (get_composition_id): Check for overflow in glyph
17322 length calculations.
17324 Integer and memory overflow fixes for display code.
17325 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17326 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17327 (scrolling_window): Check for overflow in size calculations.
17328 (line_draw_cost, realloc_glyph_pool, add_row_entry):
17329 Don't assume glyph table len fits in int.
17330 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
17331 (row_table_size): Now ptrdiff_t, not int.
17332 (scrolling_window): Avoid overflow in size calculations.
17333 Don't update size until allocation succeeds.
17334 * fns.c (concat): Check for overflow in size calculations.
17335 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
17336 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
17337 (NEXT_ALMOST_PRIME_LIMIT): New constant.
17339 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17340 (get_doc_string): Check for size calculation overflow.
17341 Don't update size until allocation succeeds.

17351 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17353 * emacs.c (main): Do not reallocate argv, since there is a null at
17354 the end that can be overwritten, and this way there's no need to
17355 worry about size-calculation overflow.
17356 (sort_args): Check for size-calculation overflow.

17365 (x_set_alpha): Do not assume XINT fits in int.
17367 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17368 This is for the members text_lines, text_cols, total_lines, total_cols,
17369 where the system imposes an 'int' limit.

17378 Check for size-calculation overflow.
17379 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17380 do, as we prefer signed integers.

17436 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17437 for command line length. Do not attempt to address one before the
17438 beginning of an array, as that's not portable.

17468 Check for size calculation overflow.
17469 (cache_face): Treat size calculation overflows as if they were
17470 memory exhaustion (the usual treatment), rather than aborting.
17472 * xfns.c (x_encode_text, x_set_name_internal)
17473 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17474 sizes, since they can exceed INT_MAX in size. Check for size

17478 (xg_select): Check for size calculation overflow.
17479 Don't update size until alloc done.
17481 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17482 as sprintf is limited to int lengths.
17484 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17485 (X_LONG_MIN): New macros.
17486 Use them to make the following changes clearer.
17487 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17488 This change doesn't affect the value now, but it may help remind
17489 future maintainers not to raise the value too much later.
17490 (SELECTION_QUANTUM): Remove, replacing with ...
17491 (selection_quantum): ... new function, which avoids overflow.
17493 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17494 assumption that selection length fits in 'int'.

17511 Don't store size until memory allocation succeeds.
17512 (x_get_window_property): Plug memory leak on memory exhaustion.
17513 Don't double-block input; malloc is safe here. Don't assume 2**34
17514 - 4 fits in unsigned long. Add an xassert to check
17515 XGetWindowProperty overflow. Be more careful about overflow
17516 calculations, and distinguish size from memory overflow better.
17517 (receive_incremental_selection): When tracing, don't assume
17518 unsigned int is less than INT_MAX.
17519 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17523 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17524 result parameters unless successful. Rely on cons_to_unsigned
17525 to report problems with elements; the old code wasn't right anyway.
17526 (x_check_property_data): Check for int overflow; we cannot use
17527 a wider type due to X limits.

17560 * lisp.h (hash_lookup, hash_put):
17561 * minibuf.c (Ftest_completion):
17562 Use ptrdiff_t for hash table indexes, not int (which is too
17563 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17564 32-bit --with-wide-int hosts).
17566 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17567 Add a FIXME comment about memory leaks.

17575 with outlandish widths.
17576 * character.h (sanitize_tab_width): Rename from sanitize_width,
17577 now that we have two such functions. All uses changed.

17596 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17597 (x_send_scroll_bar_event): Likewise. Check that the size does not
17598 exceed limits imposed by XClientMessageEvent, as well as the usual
17599 ptrdiff_t and size_t limits.

17602 (make_lispy_movement): Use same integer type in forward decl
17603 that is used in the definition.
17604 (read_key_sequence, keyremap_step):
17605 Change bufsize argument back to int, undoing my 2011-03-30 change.
17606 We prefer signed types, and int is wide enough here.
17607 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17608 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17609 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17610 length, not size_t. Use ptrdiff_t for index, not int.
17611 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17612 possibility of integer overflow.

17640 Prefer int to unsigned where either will do.
17641 (tiff_handler): New function, combining the cores of the
17642 old tiff_error_handler and tiff_warning_handler.
17643 This function is rewritten to use vsnprintf and thereby avoid
17644 stack buffer overflows. It uses only the features of vsnprintf
17645 that are common to both POSIX and native Microsoft.
17646 (tiff_error_handler, tiff_warning_handler): Use it.
17647 (tiff_load, gif_load, imagemagick_load_image):
17648 Don't assume :index value fits in 'int'.
17649 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17650 (imagemagick_load_image): Check that crop parameters fit into
17651 the integer types that MagickCropImage accepts. Don't assume
17652 Vimagemagick_render_type has a nonnegative value. Don't assume

17668 (handle_single_display_spec): If the display spec is of the form
17669 `(space ...)', and specifies display in the text area, return 2
17671 (try_cursor_movement): Check for the need to scroll more

17694 positioning on the newline at EOL of R2L text within L2R
17695 paragraph, and vice versa.
17696 (try_cursor_movement): Check continued rows, in addition to
17697 continuation rows. Fixes unwarranted scroll when point enters a
17698 continued line of R2L text within an L2R paragraph, or vice versa.
17699 (cursor_row_p): Consider the case of point being equal to
17700 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

17729 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17730 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17731 candidate is selected by the mouse, and that candidate has a
17732 composed character under the mouse.
17734 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17735 coordinates reported by pos-visible-in-window-p for a composed

17745 consider it a hit if to_charpos is anywhere in the range of the
17746 composed buffer positions.
17748 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17750 * image.c (gif_load): Don't assume that each subimage has the same
17751 dimensions as the base image. Handle disposal method that is
17752 "undefined" by the gif spec (Bug#9335).
17754 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17756 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17768 with a composed character.
17770 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17772 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17773 character bidirectional type, use STRONG_L instead. Fixes crashes
17774 in a buffer produced by `describe-categories'.
17776 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17777 members before the level stack, so they would be saved and
17778 restored when copying iterator state. Fixes incorrect reordering
17779 around TABs covered by display properties.
17781 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17783 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
17785 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
17787 * eval.c (internal_condition_case, internal_condition_case_1)
17788 (internal_condition_case_2, internal_condition_case_n):
17789 Remove unnecessary aborts (Bug#9081).
17791 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17793 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17794 has no `load' handler, try opening the file locally. (Bug#9311)
17796 2011-08-16 Ken Brown <kbrown@cornell.edu>
17798 * gmalloc.c: Expand comment.
17800 2011-08-16 Eli Zaretskii <eliz@gnu.org>
17802 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17803 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
17805 2011-08-16 Ken Brown <kbrown@cornell.edu>
17807 Fix memory allocation problems in Cygwin build (Bug#9273).
17809 * unexcw.c ( __malloc_initialized): Declare external variable.

17812 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
17814 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17816 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17817 in the static heap.
17818 [CYGWIN] (special_realloc): New function.
17819 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
17820 requests to realloc storage in the static heap.
17822 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
17824 * bidi.c (bidi_initialize): Remove unused local.
17826 2011-08-15 Eli Zaretskii <eliz@gnu.org>
17829 * biditype.h: Remove file.

17831 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
17833 * dispextern.h: Fix a typo in the comment to bidi_type_t.
17835 * chartab.c: Improve commentary for the uniprop_table API.
17837 * bidi.c (bidi_paragraph_init): Support zero value of
17838 bidi_ignore_explicit_marks_for_paragraph_level.
17839 (bidi_initialize): Use uniprop_table instead of including
17840 biditype.h and bidimirror.h.
17842 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
17843 coordinates of the iterator when restoring from ppos_it.
17846 2011-08-14 Kenichi Handa <handa@m17n.org>
17848 * process.c (create_process): Call setup_process_coding_systems
17849 after the pid of the process is set to -1 (Bug#8162).
17851 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17853 * xdisp.c (move_it_in_display_line_to): Don't invoke
17854 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17855 ppos_it. Fixes vertical cursor motion when line beginning is
17856 covered by an image. (Bug#9296)
17858 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17860 * nsterm.h (ns_run_ascript): Declare.
17861 (NSAPP_DATA2_RUNASSCRIPT): Define.
17863 * nsfns.m (as_script, as_result, as_status): New static variables.
17864 (ns_run_ascript): New function.
17865 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17866 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17867 the event loop. Get status from as_status (Bug#7276).
17869 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17870 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17871 the event loop (Bug#7276).
17873 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17875 * gnutls.c (QCgnutls_bootprop_priority)
17876 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17877 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17878 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17879 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17880 (QCgnutls_bootprop_verify_hostname_error)
17881 (QCgnutls_bootprop_callbacks_verify): Rename from
17882 Qgnutls_bootprop_..., all uses changed.
17884 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17887 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17889 * xfaces.c (Qframe_set_background_mode): Now static.
17890 * dispextern.h (Qframe_set_background_mode): Remove decl.

17894 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17896 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17897 (Fnetwork_interface_list): Allocate in increments of bytes instead
17898 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17899 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17901 (struct ifflag_def): notrailers is smart on OSX.
17902 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17903 Get hardware address with getifaddrs if available.
17905 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17907 * xdisp.c (iterate_out_of_display_property): xassert that
17908 IT->position is set to within IT->object's boundaries. Break from
17909 the loop as soon as EOB is reached; avoids infloops in redisplay
17910 when IT->position is set up wrongly due to some bug.
17911 Set IT->current to match the bidi iterator unconditionally.
17912 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17913 entry. Force push_it to save on the stack the current
17914 buffer/string position, to be restored by pop_it. Fix flags in
17915 the iterator structure wrt the object coming from a display
17916 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17917 properties. (Bug#9284)
17919 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17921 * fontset.c (fontset_get_font_group): Add proper type checks.
17924 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17926 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17927 and LC_VERSION_MIN_MACOSX.
17928 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17929 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17931 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17933 * xdisp.c (forward_to_next_line_start): Allow to use the
17934 no-display-properties-and-no-overlays under bidi display.
17935 Set disp_pos in the bidi iterator to avoid searches for display
17936 properties and overlays.
17938 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17940 * editfns.c (Fset_time_zone_rule): Document relationship with the
17943 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17944 the font entity extracted from the cache (Bug#8109).
17946 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17948 * composite.c (autocmp_chars): Don't reset point. That is done by
17949 restore_point_unwind (Bug#5984).
17951 2011-08-07 Juri Linkov <juri@jurta.org>
17953 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17954 to show the arg `TIME' instead of `TIMEVAL'.
17956 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17958 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17959 display property strides EOL and includes a newline, as in
17960 longlines-mode. (Bug#9254)
17961 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17962 word-wrap under bidirectional display. (Bug#9224)
17964 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17965 is non-zero, even if the data buffer is NULL. Fixes a crash in
17966 vertical-motion with longlines-mode. (Bug#9254)
17968 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17970 * bidi.c <bidi_cache_total_alloc>: Now static.
17971 (bidi_initialize): Initialize bidi_cache_total_alloc.
17973 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17976 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17977 amount allocated this far in `bidi_cache_total_alloc'.
17978 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17979 non-zero, only free the data buffer without restoring the cache
17980 contents. All callers changed.
17982 * dispextern.h (bidi_unshelve_cache): Update prototype.
17984 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17985 (move_it_in_display_line, move_it_to)
17986 (move_it_vertically_backward, move_it_by_lines): Replace the call
17987 to xfree to an equivalent call to bidi_unshelve_cache.
17988 (move_it_in_display_line_to): Fix logic of returning
17989 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17991 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17993 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17994 came from a string character with a `cursor' property. (Bug#9229)
17996 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17998 * Makefile.in (LIB_PTHREAD): New variable.
17999 (LIBES): Add LIB_PTHREAD (Bug#9216).
18001 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
18002 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
18004 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
18006 * regex.c (re_iswctype): Remove some redundant boolean conversions.
18008 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18010 * xterm.c (x_find_topmost_parent): New function.
18011 (x_set_frame_alpha): Find topmost parent window with
18012 x_find_topmost_parent and set the property there also (bug#9181).
18013 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
18015 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
18017 * callproc.c (Fcall_process): Avoid vfork clobbering
18018 the local vars buffer, coding_systems, current_dir.
18020 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
18022 * keymap.c (Fmake_composed_keymap): Move to subr.el.
18024 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
18026 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
18027 so that it is not optimized away.
18029 * xdisp.c (compute_display_string_pos): Remove unused local.
18031 2011-08-02 Eli Zaretskii <eliz@gnu.org>
18033 Fix slow cursor motion and scrolling in large buffers with
18034 selective display, like Org Mode buffers. (Bug#9218)
18036 * dispextern.h (struct bidi_it): New member disp_prop_p.
18038 * xdisp.c: Remove one-slot cache of display string positions.
18039 (compute_display_string_pos): Accept an additional argument
18040 DISP_PROP_P; callers changed. Scan at most 5K characters forward
18041 for a display string or property. If found, set DISP_PROP_P
18044 * bidi.c (bidi_fetch_char): Accept an additional argument
18045 DISP_PROP_P, and pass it to compute_display_string_pos.
18046 Only handle text covered by a display string if DISP_PROP_P is returned
18047 non-zero. All callers of bidi_fetch_char changed.
18049 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
18051 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
18053 2010-12-03 Don March <don@ohspite.net>
18055 * keymap.c (Fdefine_key): Fix non-prefix key error message when
18056 last character M-[char] is translated to ESC [char] (bug#7541).
18058 2011-08-02 Kenichi Handa <handa@m17n.org>
18060 * lisp.h (uniprop_table): Extern it.
18062 * chartab.c (uniprop_table): Make it non-static.
18064 2011-08-01 Eli Zaretskii <eliz@gnu.org>
18066 * xdisp.c (forward_to_next_line_start): Accept additional argument
18067 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18069 (reseat_at_next_visible_line_start): Use the bidi iterator state
18070 returned by forward_to_next_line_start to restore the state of
18071 it->bidi_it after backing up to previous newline. (Bug#9212)
18073 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18075 * regex.c (re_comp): Protoize.
18076 (re_exec): Fix return type.
18077 (regexec): Fix type of `ret'. (Bug#9203)
18079 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18081 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18082 This is needed if max-image-size is a floating-point number.
18084 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18086 * print.c (print_object): Print empty symbol as ##.
18088 * lread.c (read1): Read ## as empty symbol.
18090 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18092 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
18093 setting frame foreground color (Bug#9175).
18094 (x_set_background_color): Likewise.
18096 * nsmenu.m (-setText): Size tooltip dimensions precisely to
18097 contents (Bug#9176).
18098 (EmacsTooltip -init): Remove bezels and add shadows to
18101 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18102 or scroll bar (Bug#8470).
18104 * nsfont.m (nsfont_open): Remove assignment to voffset and
18105 unnecessary vars hshink, expand, hd, full_height, min_height.
18106 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
18108 * nsterm.h (nsfont_info): Remove voffset field.
18110 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18112 Implement strike-through and overline on NextStep (Bug#8863).
18114 * nsfont.m (nsfont_open): Use underline position provided by font,
18115 instead of hard-coded value of 2.
18116 (nsfont_draw): Call ns_draw_text_decoration instead.
18118 * nsterm.h: Add declaration for ns_draw_text_decoration.
18120 * nsterm.m (ns_draw_text_decoration): New function for drawing
18121 underline, overline, and strike-through.
18122 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
18123 ns_draw_text_decoration. Change treatment of cursor drawing to
18124 accommodate underlining, etc.
18126 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18128 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18131 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18133 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18134 Without this fix, if a signal arrives just after memory fills up,
18135 'malloc' might be invoked reentrantly.
18137 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18138 In other words, assume that every image size is allowed, on non-X
18139 hosts. This assumption is probably wrong, but it lets Emacs compile.
18141 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18143 * regex.c (re_iswctype): Convert return values to boolean.
18145 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18147 * xdisp.c (compute_display_string_pos): Don't use cached display
18148 string position if the buffer had its restriction changed.
18151 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18153 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18155 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18157 Integer signedness and overflow and related fixes. (Bug#9079)
18159 * bidi.c: Integer size and overflow fixes.
18160 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18161 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18162 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18163 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18164 (bidi_find_other_level_edge):
18165 Use ptrdiff_t instead of EMACS_INT where either will do.
18166 This works better on 32-bit hosts configured --with-wide-int.
18167 (bidi_cache_ensure_space): Check for size-calculation overflow.
18168 Use % rather than repeated addition, for better worst-case speed.
18169 Don't set bidi_cache_size until after xrealloc returns, because it
18171 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18172 (bidi_cache_ensure_space): Also check that the bidi cache size
18173 does not exceed that of the largest Lisp string or buffer. See Eli
18174 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18176 * alloc.c (__malloc_size_t): Remove.
18177 All uses replaced by size_t. See Andreas Schwab's note
18178 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18180 * image.c: Improve checking for integer overflow.
18181 (check_image_size): Assume that f is nonnull, since
18182 it is always nonnull in practice. This is one less thing to
18183 worry about when checking for integer overflow later.
18184 (x_check_image_size): New function, which checks for integer
18185 overflow issues inside X.
18186 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18187 This removes the need for a memory_full check.
18188 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18189 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18190 (xbm_read_bitmap_data): Change locals back to 'int', since
18191 their values must fit in 'int'.
18192 (xpm_load_image, png_load, tiff_load):
18193 Invoke x_create_x_image_and_pixmap earlier,
18194 to avoid much needless work if the image is too large.
18195 (tiff_load): Treat overly large images as if
18196 x_create_x_image_and_pixmap failed, not as malloc failures.
18197 (gs_load): Use x_check_image_size.
18199 * gtkutil.c: Omit integer casts.
18200 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18201 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18203 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18205 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18206 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18207 would wrongly return t on a 64-bit host.
18209 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18210 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18211 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18212 and therefore cause GCC to emit a bogus diagnostic in some cases.
18214 * image.c: Integer signedness and overflow and related fixes.
18215 This is not an exhaustive set of fixes, but it's time to
18216 record what I've got.
18217 (lookup_pixel_color, check_image_size): Remove redundant decls.
18218 (check_image_size): Don't assume that arbitrary EMACS_INT values
18219 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18220 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18221 (tiff_load, imagemagick_load_image):
18222 Check for overflow in size calculations.
18223 (x_create_x_image_and_pixmap): Remove unnecessary test for
18224 xmalloc returning NULL; that can't happen.
18225 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18226 (xpm_color_bucket): Use better integer hashing function.
18227 (xpm_cache_color): Don't possibly over-allocate memory.
18228 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18229 (gif_memory_source):
18230 Use ptrdiff_t, not int or size_t, to record sizes.
18231 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18232 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18233 either works, as we prefer signed integers.
18234 (tiff_read_from_memory, tiff_write_from_memory):
18235 Return tsize_t, not size_t, since that's what the TIFF API wants.
18236 (tiff_read_from_memory): Don't fail simply because the read would
18237 go past EOF; instead, return a short read.
18238 (tiff_load): Omit no-longer-needed casts.
18239 (Fimagemagick_types): Don't assume size fits into 'int'.
18241 Improve hashing quality when configured --with-wide-int.
18242 * fns.c (hash_string): New function, taken from sxhash_string.
18243 Do not discard information about ASCII character case; this
18244 discarding is no longer needed.
18245 (sxhash-string): Use it. Change sig to match it. Caller changed.
18246 * lisp.h: Declare it.
18247 * lread.c (hash_string): Remove, since we now use fns.c's version.
18248 The fns.c version returns a wider integer if --with-wide-int is
18249 specified, so this should help the quality of the hashing a bit.
18251 * emacs.c: Integer overflow minor fix.
18252 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18253 Define only if GNU_LINUX.
18254 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18256 * dispnew.c: Integer signedness and overflow fixes.
18257 Remove unnecessary forward decls, that were a maintenance hassle.
18258 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18260 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18261 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18262 (prepare_desired_row, line_draw_cost):
18263 Use int, not unsigned, where either works.
18264 (save_current_matrix, restore_current_matrix):
18265 Use ptrdiff_t, not size_t, where either works.
18266 (init_display): Check for overflow more accurately, and without
18267 relying on undefined behavior.
18269 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18270 Remove, replacing with the new symbols in lisp.h. All uses changed.
18271 * fileio.c (make_temp_name):
18272 * filelock.c (lock_file_1, lock_file):
18273 * xdisp.c (message_dolog):
18274 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18275 Use pMd etc. instead.
18276 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18277 replacing the pWIDE etc. symbols removed from editfns.c.
18279 * keyboard.h (num_input_events): Now uintmax_t.
18280 This is (very slightly) less likely to mess up due to wraparound.
18283 * buffer.c: Integer signedness fixes.
18284 (alloc_buffer_text, enlarge_buffer_text):
18285 Use ptrdiff_t rather than size_t when either will do, as we prefer
18288 * alloc.c: Integer signedness and overflow fixes.
18289 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18290 (__malloc_size_t): Default to size_t, not to int.
18291 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18292 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18293 Prefer ptrdiff_t to size_t when either would do, as we prefer
18295 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18296 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18297 Now const. Initialize with values that are in range even if char
18299 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18300 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18301 These functions do the right thing with sizes > 2**32.
18302 (check_depth): Now ptrdiff_t, not int.
18303 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18304 Adjust to new way of storing sizes. Check for size overflow bugs
18306 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18307 slightly wrong anyway, as it missed one instance of
18308 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18309 (refill_memory_reserve): Omit needless cast to size_t.
18310 (mark_object_loop_halt): Mark as externally visible.
18312 * xselect.c: Integer signedness and overflow fixes.
18313 (Fx_register_dnd_atom, x_handle_dnd_message):
18314 Use ptrdiff_t, not size_t, since we prefer signed.
18315 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18316 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18317 x_dnd_atoms_size and x_dnd_atoms_length.
18319 * doprnt.c: Prefer signed to unsigned when either works.
18321 * doprnt.c (doprnt):
18323 * xdisp.c (vmessage):
18324 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18325 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18326 prefer signed arithmetic to avoid comparison confusion.
18327 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18328 but is a bit tricky.
18330 Assume freestanding C89 headers, string.h, stdlib.h.
18331 * data.c, doprnt.c, floatfns.c, print.c:
18332 Include float.h unconditionally.
18333 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18334 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18335 * regex.c: Likewise for stddef.h, string.h.
18336 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18337 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18338 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18339 (STDC_HEADERS): Remove obsolete defines.
18340 * sysdep.c: Include limits.h unconditionally.
18342 Assume support for memcmp, memcpy, memmove, memset.
18343 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18344 * regex.c (memcmp, memcpy):
18345 Remove; we assume C89 now.
18347 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18348 (__malloc_safe_bcopy): Remove; no longer needed.
18350 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18351 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18352 well either way, and we prefer signed to unsigned.
18354 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18356 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18357 closes the connection while we're reading (bug#9182).
18359 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18361 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18362 are specified (Bug#9168).
18364 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18366 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18367 Found by GCC static checking and --with-wide-int on a 32-bit host.
18369 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18371 * xdisp.c (compute_display_string_pos): Fix logic of caching
18372 previous display string position. Initialize cached_prev_pos to
18373 -1. Fixes slow-down at the beginning of a buffer.
18375 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18377 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18378 for attrs[LFACE_FONTSET_INDEX].
18380 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18382 * xml.c (parse_region): Remove unused local
18383 that was recently introduced.
18385 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18387 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18388 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18390 * xdisp.c (move_it_in_display_line_to): Record the best matching
18391 position for TO_CHARPOS while scanning the line, and restore it on
18392 exit if none of the characters scanned was an exact match.
18393 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18394 when exact match is impossible due to invisible text, and the
18395 lines are truncated.
18397 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18399 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18402 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18404 Fix a significant slow-down of cursor motion with C-n, C-p,
18405 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18406 auto-repeat under bidi redisplay in fontified buffers.
18407 * xdisp.c (compute_stop_pos_backwards): New function.
18408 (next_element_from_buffer): Call compute_stop_pos_backwards to
18409 find a suitable prev_stop when we find ourselves before
18411 (reseat): Don't look for prev_stop, as that could mean a very long
18413 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18414 <cached_disp_overlay_modiff>: Cache for last found display string
18416 (compute_display_string_pos): Return the cached position if asked
18417 about the same buffer in the same area of character positions, and
18418 the buffer wasn't changed since the time the display string
18419 position was cached.
18421 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18423 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18424 is an integer, which is important for empty lines. (Bug#9149)
18426 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18428 * frame.c (Fmodify_frame_parameters): In tty case, update the
18429 default face if necessary (Bug#4238).
18431 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18433 * editfns.c (Fstring_to_char): No need to explain what a character
18434 is in the docstring (Bug#6576).
18436 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18438 * xml.c (parse_region): Make sure we always return a tree.
18440 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18442 * xml.c (parse_region): If a document contains only comments,
18445 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18447 * xml.c (make_dom): Return comments, too.
18449 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18452 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18453 and the surrounding thread.
18454 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18455 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18456 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18458 * s/openbsd.h (BROKEN_SIGIO): Define.
18459 * unexelf.c (unexec) [__OpenBSD__]:
18460 Don't update the .mdebug section of the Alpha COFF symbol table.
18462 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18464 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18467 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18469 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18470 This fixes some race conditions on the permissions of any newly
18473 * alloc.c (valid_pointer_p): Use pipe, not open.
18474 This fixes some permissions issues when debugging.
18476 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18477 If fchown fails to set both uid and gid, try to set just gid,
18478 as that is sometimes allowed. Adjust the file's mode to eliminate
18479 setuid or setgid bits that are inappropriate if fchown fails.
18481 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18483 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18484 to compare Lisp_Objects.
18485 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18486 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18487 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18489 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18491 * lread.c (read_integer): Unread even EOF character.
18492 (read1): Likewise. Properly record start position of symbol.
18494 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18495 symbol character follows.
18497 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18499 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18500 This works around a problem with the previous change to Fcopy_file.
18501 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18502 and without this change, GCC might complain about discarding
18503 fchown's return value.
18505 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18507 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18509 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18511 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18513 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18515 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18516 it's used from the C level.
18518 * process.c: Use the same condition for POLL_FOR_INPUT in both
18519 keyboard.c and process.c (bug#1858).
18521 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18523 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18524 (Fgnutls_boot): Use it.
18526 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18528 * doc.c (Fsubstitute_command_keys): Revert last change.
18530 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18532 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18533 quotes the next character, and doesn't affect other longer
18534 sequences (bug#8935).
18536 * lread.c (syms_of_lread): Clarify that is isn't only
18537 `eval-buffer' and `eval-defun' that's affected by
18538 `lexical-binding' (bug#8460).
18540 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18542 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18543 bidi redisplay when a line includes both an image and is truncated.
18545 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18547 Fix minor problems found by static checking.
18548 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18549 (elsz): Now a signed constant, not a size_t var. We prefer signed
18550 types to unsigned, to avoid integer comparison confusion. Without
18551 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18552 "cannot optimize loop, the loop counter may overflow", a symptom
18554 * indent.c (Fvertical_motion): Mark locals as initialized.
18555 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18557 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18559 * search.c (Fre_search_backward): Mention `case-fold-search' in
18560 all the re_search_* functions (bug#8138).
18562 * keyboard.c (Fopen_dribble_file): Document when the file is
18565 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18567 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18570 Support bidi reordering of display and overlay strings.

18572 (compute_display_string_end): Accept additional argument STRING.
18573 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18574 (reseat_to_string): Initialize bidi_it->string.s and
18575 bidi_it->string.schars.
18576 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18577 NULL (avoids a crash in bidi_paragraph_init).
18578 Initialize itb.string.lstring.
18579 (init_iterator): Call bidi_init_it only of a valid
18580 buffer position was specified. Initialize paragraph_embedding to
18582 (reseat_to_string): Initialize the bidi iterator.
18583 (display_string): If we need to ignore text properties of
18584 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18585 original value of -1 will not work with bidi.)
18586 (compute_display_string_pos): First arg is now struct
18587 `text_pos *'; all callers changed. Support display properties on
18589 (compute_display_string_end): Support display properties on Lisp
18591 (init_iterator, reseat_1, reseat_to_string): Initialize the
18592 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18593 when iterating on a string not from display properties).
18594 (compute_display_string_pos, compute_display_string_end):
18595 Fix calculation of the object to scan. Fixes an error when using
18597 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18598 base_level_stop; instead, set base_level_stop to BEGV.
18599 Fixes crashes in vertical-motion.
18600 (next_element_from_buffer): Improve commentary for when
18601 the iterator is before prev_stop.
18602 (init_iterator): Initialize bidi_p from the default value of
18603 bidi-display-reordering, not from buffer-local value. Use the
18604 buffer-local value only if initializing for buffer iteration.
18605 (handle_invisible_prop): Support invisible properties on strings
18606 that are being bidi-reordered.
18607 (set_iterator_to_next): Support bidi reordering of C strings and
18609 (next_element_from_string): Support bidi reordering of Lisp
18611 (handle_stop_backwards): Support Lisp strings as well.
18612 (display_string): Support display of R2L glyph rows.
18613 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18614 (init_iterator): Don't initialize it->bidi_p for strings
18616 (reseat_to_string): Initialize it->bidi_p for strings here.
18617 (next_element_from_string, next_element_from_c_string)
18618 (next_element_from_buffer): Add xassert's for correspondence
18619 between IT's object being iterated and it->bidi_it.string
18621 (face_before_or_after_it_pos): Support bidi iteration.
18622 (next_element_from_c_string): Handle the case of the first string
18623 character that is not the first one in the visual order.
18624 (get_visually_first_element): New function, refactored from common
18625 parts of next_element_from_buffer, next_element_from_string, and
18626 next_element_from_c_string.
18627 (tool_bar_lines_needed, redisplay_tool_bar)
18628 (display_menu_bar): Force left-to-right direction. Add a FIXME
18629 comment for making that be controlled by a user option.
18630 (push_it, pop_it): Save and restore the state of the
18631 bidi iterator. Save and restore the bidi_p flag.
18632 (pop_it): Iterate out of display property for string iteration as
18634 (iterate_out_of_display_property): Support iteration over strings.
18635 (handle_single_display_spec): Set up it->bidi_it for iteration
18636 over a display string, and call bidi_init_it.
18637 (handle_single_display_spec, next_overlay_string)
18638 (get_overlay_strings_1, push_display_prop): Set up the bidi
18639 iterator for displaying display or overlay strings.
18640 (forward_to_next_line_start): Don't use the shortcut if
18642 (back_to_previous_visible_line_start): If handle_display_prop
18643 pushed the iterator stack, restore the internal state of the bidi
18644 iterator by calling bidi_pop_it same number of times.
18645 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18646 and we are bidi-iterating, don't decrement the iterator position;
18647 instead, set the first_elt flag in the bidi iterator, to produce
18649 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18650 (push_display_prop): xassert that we are iterating a buffer.
18651 (push_it, pop_it): Save and restore paragraph_embedding member.
18652 (handle_single_display_spec, next_overlay_string)
18653 (get_overlay_strings_1, reseat_1, reseat_to_string)
18654 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18655 correctly. Don't assume unibyte strings are not bidi-reordered.
18656 (compute_display_string_pos)
18657 (compute_display_string_end): Fix handling the case of C string.
18658 (push_it, pop_it): Save and restore from_disp_prop_p.
18659 (handle_single_display_spec, push_display_prop): Set the
18660 from_disp_prop_p flag.
18661 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
18662 (pop_it): Call iterate_out_of_display_property only if we are
18663 popping after iteration over a string that came from a display
18664 property. Fix a typo in popping stretch info. Add an assertion
18665 for verifying that the iterator position is in sync with the bidi
18667 (handle_single_display_spec, get_overlay_strings_1)
18668 (push_display_prop): Fix initialization of paragraph direction for
18669 string when that of the parent object is not yet determined.
18670 (reseat_1): Call bidi_init_it to resync the bidi
18671 iterator with IT's position. (Bug#7616)
18672 (find_row_edges): If ROW->start.pos gives position
18673 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

19118 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
19120 Random fixes. E.g., (random) never returned negative values.
19121 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19122 subseconds part to the entropy, as that's a bit more random.
19123 Prefer signed to unsigned, since the signedness doesn't matter and
19124 in general we prefer signed. When given a limit, use a
19125 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19126 latter isn't right if USE_2_TAGS_FOR_INTS.
19127 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19128 not 0..VALMASK. Don't discard "excess" bits that random () returns.
19130 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
19132 * textprop.c (text_property_stickiness):
19133 Obey Vtext_property_default_nonsticky.

19140 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19141 This is more efficient than Ffile_directory_p and avoids a minor race.
19143 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19145 * buffer.c (Foverlay_put): Say what the return value is
19148 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19149 is a directory before asking whether to use the file name
19151 (barf_or_query_if_file_exists): Make the "File is a directory"
19152 error be more correct.
19154 * fns.c (Frequire): Remove the mention of the .gz files, since
19155 that's installation-specific, but keep the mention of
19156 `get-load-suffixes'.
19158 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
19160 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

19165 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
19166 (syms_of_gnutls): Remove duplicate DEFSYM for
19167 Qgnutls_bootprop_verify_hostname_error, an error for
19168 Qgnutls_bootprop_verify_error (which is no longer used).
19170 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19171 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19172 Also (re)move comments that are misplaced or no longer relevant.
19174 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
19176 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

19204 * fns.c (Frequire): Mention .el.gz files (bug#7314).
19205 (Frequire): Mention get-load-suffixes.

19273 * eval.c (struct backtrace): Simplify and port the data structure.
19274 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19275 signed bit field, as this assumption is not portable and it makes
19276 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19277 "char debug_on_exit : 1" as this is not portable either; instead,
19278 use the portable "unsigned int debug_on_exit : 1". Remove unused
19279 member evalargs. Remove obsolete comments about cc bombing out.
19281 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19351 (emacs_fixed_get_preferred_height): Use min_width/height from
19352 frames size_hint to set minimum and natural (Bug#8919).
19353 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
19354 and use min_width/height from frames size_hint to set
19355 min_width/height (Bug#8919).

19447 * print.c (printchar, strout): Check for string overflow.
19448 (PRINTPREPARE, printchar, strout):
19449 Don't set size unless allocation succeeds.
19451 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19452 for sizes. Check for string overflow more accurately.

19466 (read_integer): Radix is now EMACS_INT, not int,
19467 to improve quality of diagnostics for out-of-range radices.
19468 Calculate buffer size correctly for out-of-range radices.
19469 (read1): Check for integer overflow in radices, and in
19470 read-circle numbers.
19471 (read_escape): Avoid int overflow.
19472 (Fload, openp, read_buffer_size, read1)
19473 (substitute_object_recurse, read_vector, read_list, map_obarray):

19496 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19497 The following patches are for when GLYPH_DEBUG && !XASSERT.
19498 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19499 * dispnew.c (flush_stdout):
19500 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19501 Mark as externally visible.
19502 * dispnew.c (check_window_matrix_pointers): Now static.
19503 * dispnew.c (window_to_frame_vpos):
19504 * xfns.c (unwind_create_frame):

19511 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19513 (debug_method_add): Use va_list and vsprintf rather than relying
19514 on undefined behavior with wrong number of arguments.
19515 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19516 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19517 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19518 since we're not interested in debugging glyphs with old libraries.
19519 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19520 GCC 4.6.0's static checking.
19522 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

19551 * xfaces.c (face_at_buffer_position):
19552 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19553 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19554 (Fnext_overlay_change, Fprevious_overlay_change)
19555 (mouse_face_overlay_overlaps, Foverlays_in):
19556 Use ptrdiff_t, not int, for sizes.
19557 (overlays_at, overlays_in): Check for size-calculation overflow.
19559 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19561 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19562 (x_session_initialize): Do not assume string length fits in int.
19564 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19565 This is unlikely, but can occur if DPI is outlandish.
19567 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19568 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19570 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19571 * xrdb.c (magic_file_p, search_magic_path):
19572 Omit last arg SUFFIX; it was always 0. All callers changed.
19573 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19575 * xfont.c (xfont_match): Avoid need for strlen.
19577 * xfns.c: Don't assume strlen fits in int.
19578 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19580 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19581 not unsigned long, as we prefer signed integers. All callers changed.
19582 Detect integer overflow in repeat count.
19583 (message_dolog): Don't assume print length fits in 39 bytes.
19584 (display_mode_element): Don't assume strlen fits in int.
19586 * termcap.c: Don't assume sizes fit in int and never overflow.
19587 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19588 (gobble_line): Check for size-calculation overflow.
19590 * minibuf.c (Fread_buffer):
19591 * lread.c (intern, intern_c_string):
19592 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19593 Don't assume string length fits in int.
19595 * keyboard.c (parse_tool_bar_item):
19596 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19598 * font.c: Don't assume string length fits in int.
19599 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19600 Use ptrdiff_t, not int.
19601 (font_intern_prop): Don't assume string length fits in int.
19602 Don't assume integer property fits in fixnum.
19603 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19605 * filelock.c: Fix some buffer overrun and integer overflow issues.
19606 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19607 Reformulate so as not to need the command string.
19608 Invoke gzip -cd rather than gunzip, as it's more portable.
19609 (lock_info_type, lock_file_1, lock_file):
19610 Don't assume pid_t and time_t fit in unsigned long.
19611 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19612 (current_lock_owner): Prefer signed type for sizes.
19613 Use memcpy, not strncpy, where memcpy is what is really wanted.
19614 Don't assume (via atoi) that time_t and pid_t fit in int.
19615 Check for time_t and/or pid_t out of range, e.g., via a network share.
19616 Don't alloca where an auto var works fine.
19618 * fileio.c: Fix some integer overflow issues.
19619 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19620 Don't assume string length fits in int.
19621 (directory_file_name): Don't assume string length fits in long.
19622 (make_temp_name): Don't assume pid fits in int, or that its print
19623 length is less than 20.
19625 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19627 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19629 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19631 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19632 We prefer signed integers, even for size calculations.
19634 * emacs.c: Don't assume string length fits in 'int'.
19635 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19636 (main): Don't invoke strlen when not needed.
19638 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19639 (XD_DEBUG_MESSAGE): Don't waste a byte.
19641 * callproc.c (getenv_internal_1, getenv_internal)
19642 (Fgetenv_internal):
19643 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19645 * lread.c (invalid_syntax): Omit length argument.
19646 All uses changed. This doesn't fix a bug, but it simplifies the
19647 code away from its former Hollerith-constant appearance, and it's
19648 one less 'int' to worry about when looking at integer-overflow issues.
19649 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19651 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19652 This didn't break anything, but it didn't help either.
19653 It's confusing to put a bogus integer in a place where the actual
19654 value does not matter.
19655 (LIST_END_P): Remove unused macro and its bogus comment.
19656 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19658 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19659 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19661 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19662 We prefer signed types, and the value cannot exceed the EMACS_INT
19663 range anyway (because otherwise the length would not be representable).
19664 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19665 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19666 This avoids a GCC warning when WIDE_EMACS_INT.
19668 * indent.c (sane_tab_width): New function.
19669 (current_column, scan_for_column, Findent_to, position_indentation)
19670 (compute_motion): Use it. This is just for clarity.
19671 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19673 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19675 * lisp.h (lint_assume): New macro.
19676 * composite.c (composition_gstring_put_cache):
19677 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19679 * editfns.c, insdel.c:
19680 Omit unnecessary forward decls, to simplify future changes.
19682 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19684 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19686 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19687 Use much-faster test for byte-length change.
19688 Don't assume string byte-length fits in 'int'.
19689 Check that character arg fits in 'int'.
19690 (mapcar1): Declare byte as byte, for clarity.
19692 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19694 * fns.c (concat): Catch string overflow earlier.
19695 Do not rely on integer wraparound.
19697 * dispextern.h (struct it.overlay_strings_charpos)
19698 (struct it.selective): Now EMACS_INT, not int.
19699 * xdisp.c (forward_to_next_line_start)
19700 (back_to_previous_visible_line_start)
19701 (reseat_at_next_visible_line_start, next_element_from_buffer):
19702 Don't arbitrarily truncate the value of 'selective' to int.
19704 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19706 * composite.c: Don't truncate sizes to 'int'.
19707 (composition_gstring_p, composition_reseat_it)
19708 (composition_adjust_point): Use EMACS_INT, not int.
19709 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19710 not EMACS_UINT, for indexes.
19712 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19714 * buffer.c: Include <verify.h>.
19715 (struct sortvec.priority, struct sortstr.priority):
19716 Now EMACS_INT, not int.
19717 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19718 (struct sortstr.size, record_overlay_string)
19719 (struct sortstrlist.size, struct sortlist.used):
19720 Don't truncate size to int.
19721 (record_overlay_string): Check for size-calculation overflow.
19722 (init_buffer_once): Check at compile-time, not run-time.
19724 2011-06-22 Jim Meyering <meyering@redhat.com>
19726 Don't leak an XBM-image-sized buffer
19727 * image.c (xbm_load): Free the image buffer after using it.
19729 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19732 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19733 that Sun C diagnosed.
19734 * fns.c (secure_hash): Fix pointer signedness issue.
19735 * intervals.c (static_offset_intervals): New function.
19736 (offset_intervals): Use it.
19738 2011-06-21 Leo Liu <sdl.web@gmail.com>
19741 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19744 * fns.c (secure_hash): Rename from crypto_hash_function and change
19745 the first arg to accept symbols.
19746 (Fsecure_hash): New primitive.
19747 (syms_of_fns): New symbols.
19749 2011-06-20 Deniz Dogan <deniz@dogan.se>
19751 * process.c (Fset_process_buffer): Clarify return value in
19754 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19756 * dispnew.c (add_window_display_history): Use BVAR.
19758 * xdisp.c (debug_method_add): Use BVAR.
19759 (check_window_end, dump_glyph_matrix, dump_glyph)
19760 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19762 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19765 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19766 check till after the cache is created in init_frame_faces.
19768 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19770 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19772 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19774 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19775 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19776 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19778 Improve buffer-overflow checking (Bug#8873).
19779 * fileio.c (Finsert_file_contents):
19780 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19781 Remove the old (too-loose) buffer overflow checks.
19782 They weren't needed, since make_gap checks for buffer overflow.
19783 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19784 The old code merely checked for Emacs fixnum overflow, and relied
19785 on undefined (wraparound) behavior. The new code avoids undefined
19786 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19788 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19789 Tune. Don't use wider integers than needed. Don't use alloca.
19790 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19792 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19794 * insdel.c, lisp.h (buffer_overflow): New function.
19795 (insert_from_buffer_1, replace_range, replace_range_2):
19796 * insdel.c (make_gap_larger):
19797 * editfns.c (Finsert_char):
19798 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19800 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19802 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19804 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19806 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19807 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19809 * fileio.c: Don't assume EMACS_INT fits in off_t.
19810 (emacs_lseek): New static function.
19811 (Finsert_file_contents, Fwrite_region): Use it.
19812 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19814 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19816 * fns.c: Don't overflow int when computing a list length.
19817 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19818 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19819 truncation on 64-bit hosts. Check for QUIT every
19820 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19821 faster and is responsive enough.
19822 (Flength): Report an error instead of overflowing an integer.
19823 (Fsafe_length): Return a float if the value is not representable
19824 as a fixnum. This shouldn't happen except in contrived situations.
19825 (Fnthcdr, Fsort): Don't assume list length fits in int.
19826 (Fcopy_sequence): Don't assume vector length fits in int.
19828 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19829 (header_size, word_size): New constants.
19830 (allocate_vectorlike): Don't check size overflow here.
19831 (allocate_vector): Check it here instead, since this is the only
19832 caller of allocate_vectorlike that could cause overflow.
19833 Check that the new vector's length is representable as a fixnum.
19835 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19836 The previous code was bogus. For example, next_almost_prime (32)
19837 returned 39, which is undesirable as it is a multiple of 3; and
19838 next_almost_prime (24) returned 25, which is a multiple of 5 so
19839 why was the code bothering to check for multiples of 7?
19841 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19843 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19845 Variadic C functions now count arguments with ptrdiff_t.
19846 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19847 Back then I didn't know that the Emacs coding style prefers signed int.
19848 Also, in the meantime I found a few more instances where arguments
19849 were being counted with int, which may truncate counts on 64-bit
19850 machines, or EMACS_INT, which may be unnecessarily wide.
19851 * lisp.h (struct Lisp_Subr.function.aMANY)
19852 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19853 Arg counts are now ptrdiff_t, not size_t.
19854 All variadic functions and their callers changed accordingly.
19855 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19856 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19857 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19858 * callint.c (Fcall_interactively): Check arg count for overflow,
19859 to avoid potential buffer overrun. Use signed char, not 'int',
19860 for 'varies' array, so that we needn't bother to check its size
19861 calculation for overflow.
19862 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19863 * eval.c (apply_lambda):
19864 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19865 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19866 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19868 * callint.c (Fcall_interactively): Don't use index var as event count.
19870 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19871 * mem-limits.h (SIZE): Remove; no longer used.
19873 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19875 Remove unnecessary casts.
19876 * xterm.c (x_term_init):
19877 * xfns.c (x_set_border_pixel):
19878 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19879 These aren't needed now that we assume ANSI C.
19881 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19882 It's more likely to cause problems (due to unsigned overflow)
19885 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19887 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19889 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19891 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19893 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19895 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19897 GLYPH_CODE_FACE returns EMACS_INT, not int.
19898 * dispextern.h (merge_faces):
19899 * xfaces.c (merge_faces):
19900 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19901 Don't assume EMACS_INT fits in int.
19903 * character.h (CHAR_VALID_P): Remove unused parameter.
19904 * fontset.c, lisp.h, xdisp.c: All uses changed.
19906 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19908 * fns.c (concat): Minor tuning based on overflow analysis.
19909 This doesn't fix any bugs. Use int to hold character, instead
19910 of constantly refetching from Emacs object. Use XFASTINT, not
19911 XINT, for value known to be a character. Don't bother comparing
19912 a single byte to 0400, as it's always less.
19914 * floatfns.c (Fexpt):
19915 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19917 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19920 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19922 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19923 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19924 incorrectly succeed when S was a string, because 4294967386 was
19925 truncated before it was used.
19927 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19928 Otherwise, an out-of-range integer could cause undefined behavior
19931 * composite.c: Use int, not EMACS_INT, for characters.
19932 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19933 EMACS_INT, for values that are known to be in character range.
19934 This doesn't fix any bugs but is the usual style inside Emacs and
19935 may generate better code on 32-bit machines.
19937 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19938 This is for reasons similar to the recent CHAR_STRING fix.
19939 * charset.c (Fencode_char): Check that character arg is actually
19940 a character. Pass an int to ENCODE_CHAR.
19941 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19942 wider than 'int', as a compile-time check to prevent future regressions
19945 * character.c (char_string): Remove unnecessary casts.
19947 Make sure a 64-bit char is never passed to CHAR_STRING.
19948 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19949 by silently ignoring the top 32 bits, allowing some values
19950 that were far too large to be valid characters.
19951 * character.h: Include <verify.h>.
19952 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19953 arguments are no wider than unsigned, as a compile-time check
19954 to prevent future regressions in this area.
19956 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19957 (Fsubst_char_in_region):
19959 * xdisp.c (decode_mode_spec_coding):
19960 Adjust to CHAR_STRING's new requirement.
19961 * editfns.c (Finsert_char, Fsubst_char_in_region):
19962 * fns.c (concat): Check that character args are actually
19963 characters. Without this test, these functions did the wrong
19964 thing with wildly out-of-range values on 64-bit hosts.
19966 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19967 These casts should not be needed on 32-bit hosts, either.
19968 * keyboard.c (read_char):
19969 * lread.c (Fload): Remove casts to unsigned.
19971 * lisp.h (UNSIGNED_CMP): New macro.
19972 This fixes comparison bugs on 64-bit hosts.
19973 (ASCII_CHAR_P): Use it.
19974 * casefiddle.c (casify_object):
19975 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19976 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19977 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19978 * dispextern.h (FACE_FROM_ID):
19979 * keyboard.c (read_char): Use UNSIGNED_CMP.
19981 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19982 not to EMACS_INT, to avoid GCC warning.
19984 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19986 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19987 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19988 isn't needed on 32-bit machines.
19990 * buffer.c (Fgenerate_new_buffer_name):
19991 Use EMACS_INT for count, not int.
19992 (advance_to_char_boundary): Return EMACS_INT, not int.

20623 instead of using explicit *_CHAR codes.
20624 (bidi_resolve_explicit, bidi_resolve_weak):

20633 (bidi_level_of_next_char): Don't try to lookup the cache for the
20634 next/previous character if nothing is cached there yet, or if we
20635 were just reseat()'ed to a new position.
20637 * xdisp.c (set_cursor_from_row): Set start and stop points
20638 according to the row's direction when priming the loop that looks
20639 for the glyph on which to display cursor.

20641 (display_prop_intangible_p): Reimplement to call
20642 handle_display_spec instead of single_display_spec_intangible_p.
20643 Accept 3 additional arguments needed by handle_display_spec.
20644 This fixes incorrect cursor motion across display property with complex
20645 values: lists, `(when COND...)' forms, etc.

20647 lists with the argument STRING its top-level element.
20648 (display_prop_string_p): Fix the condition for processing a

20652 (compute_display_string_pos): Accept additional argument
20653 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20654 value of a `display' property is a "replacing spec".
20655 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20656 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20657 the display property, but just return a value indicating whether
20658 the display property will replace the characters it covers.
20659 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20660 frame_window_p members of struct bidi_it.
20661 (compute_display_string_pos, compute_display_string_end):

20686 * gnutls.c: Use Emacs's memory allocators.
20687 Without this change, the gnutls library would invoke malloc etc.
20688 directly, which causes problems on non-SYNC_INPUT hosts, and which
20689 runs afoul of improving memory_full behavior. (Bug#8761)
20690 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20691 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20692 xfree instead of the default malloc, realloc, free.
20693 (Fgnutls_boot): No need to check for memory allocation failure,
20694 since xmalloc does that for us.
20696 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

20716 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20717 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20718 * alloc.c (allocate_vectorlike):
20719 Check for overflow in vector size calculations.
20720 * ccl.c (ccl_driver):
20721 Check for overflow when converting EMACS_INT to int.

20723 need to be updated by these changes.
20724 * fns.c (make_hash_table, maybe_resize_hash_table):
20725 Check for integer overflow with large hash tables.
20726 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20727 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20728 (SXHASH_REDUCE): New macro.
20729 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20730 Use it instead of discarding useful hash info with large hash values.
20731 (sxhash_float): New function.
20732 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20733 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20734 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20735 Rewrite to use FIXNUM_BITS, as this simplifies things.
20736 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20737 Adjust signatures to match updated version of code.
20738 (consing_since_gc): Now EMACS_INT, since a single hash table can
20739 use more than INT_MAX bytes.

20788 Make it possible to run ./temacs.
20790 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20791 syms_of_callproc does the same thing. Remove test for

20852 * fns.c (to_uchar): Define.
20853 (crypto_hash_function): Use it to convert some newly-signed

20865 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20866 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20867 to hold a serial number that is too large for a fixnum.
20868 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20869 Check for serial numbers out of range. Decode any serial number
20870 that was so large that it became a float. (Bug#8722)
20872 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20873 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20874 Use XFASTINT rather than XUINT when numbers are nonnegative.
20875 (xd_append_arg, Fdbus_method_return_internal):
20876 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20877 arguments, check that Lisp number is nonnegative, rather than
20878 silently wrapping negative numbers around. (Bug#8722)
20879 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20882 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20884 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20886 ccl: Add integer overflow checks.
20887 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20888 (IN_INT_RANGE): New macros.
20889 (ccl_driver): Use them to check for integer overflow when
20890 decoding a CCL program. Many of the new checks are whether XINT (x)
20891 fits in int; it doesn't always, on 64-bit hosts. The new version
20892 doesn't catch all possible integer overflows, but it's an
20893 improvement. (Bug#8719)
20895 * alloc.c (make_event_array): Use XINT, not XUINT.
20896 There's no need for unsigned here.
20898 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20899 This follows up to the 2011-05-06 change that substituted uintptr_t
20900 for EMACS_INT. This case wasn't caught back then.
20902 Rework Fformat to avoid integer overflow issues.
20903 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20904 now (part of C89). Include <verify.h>.
20905 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20906 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20907 (Fformat): Avoid the prepass trying to compute sizes; it was only
20908 approximate and thus did not catch overflow reliably. Instead, walk
20909 through the format just once, formatting and computing sizes as we go,
20910 checking for integer overflow at every step, and allocating a larger
20911 buffer as needed. Keep track separately whether the format is
20912 multibyte. Keep only the most-recently calculated precision, rather
20913 than them all. Record whether each argument has been converted to
20914 string. Use EMACS_INT, not int, for byte and char and arg counts.
20915 Support field widths and precisions larger than INT_MAX. Avoid
20916 sprintf's undefined behavior with conversion specifications such as %#d
20917 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20918 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20919 formatting out-of-range floating point numbers with int
20920 formats. (Bug#8668)
20922 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20924 * data.c: Avoid integer truncation in expressions involving floats.
20925 * data.c: Include <intprops.h>.
20926 (arith_driver): When there's an integer overflow in an expression
20927 involving floating point, convert the integers to floating point
20928 so that the resulting value does not suffer from catastrophic
20929 integer truncation. For example, on a 64-bit host (* 4
20930 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20931 Do not rely on undefined behavior after integer overflow.
20933 merge count_size_as_multibyte, parse_str_to_multibyte
20934 * character.c, character.h (count_size_as_multibyte):
20935 Rename from parse_str_to_multibyte; all uses changed.
20936 Check for integer overflow.
20937 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20938 since it's now a duplicate of the other. This is more of
20939 a character than a buffer op, so better that it's in character.c.
20940 * fns.c, print.c: Adjust to above changes.
20942 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20944 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20946 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20948 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20949 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20950 (x_clipboard_manager_save): Now static.
20951 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20953 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20954 (crypto_hash_function): Now static.
20955 Fix pointer signedness problems. Avoid unnecessary initializations.
20957 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20959 * termhooks.h (Vselection_alist): Make it terminal-local.
20961 * terminal.c (create_terminal): Initialize it.
20963 * xselect.c: Support for clipboard managers.
20964 (Vselection_alist): Move to termhooks.h as terminal-local var.
20965 (LOCAL_SELECTION): New macro.
20966 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20967 (symbol_to_x_atom): Remove gratuitous arg.
20968 (x_handle_selection_request, lisp_data_to_selection_data)
20969 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20970 (x_own_selection, x_get_local_selection, x_convert_selection):
20971 New arg, specifying work frame. Use terminal-local Vselection_alist.
20972 (some_frame_on_display): Delete unused function.
20973 (Fx_own_selection_internal, Fx_get_selection_internal)
20974 (Fx_disown_selection_internal, Fx_selection_owner_p)
20975 (Fx_selection_exists_p): New optional frame arg.
20976 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20977 (x_handle_selection_clear): Don't treat other terminals with the
20978 same keyboard specially. Use the terminal-local Vselection_alist.
20979 (x_clear_frame_selections): Use Frun_hook_with_args.
20981 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20983 * xterm.h: Add support for those atoms.
20985 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20987 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20988 (converted_selections, conversion_fail_tag): New global variables.
20989 (x_selection_request_lisp_error): Free the above.
20990 (x_get_local_selection): Remove unnecessary code.
20991 (x_reply_selection_request): Args changed; handle arbitrary array
20992 of converted selections stored in converted_selections.
20993 Separate the XChangeProperty and SelectionNotify steps.
20994 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20995 (x_convert_selection): New function.
20996 (x_handle_selection_event): Simplify.
20997 (x_get_foreign_selection): Don't ignore incoming requests while
20998 waiting for an answer; this will fail when we implement
20999 SAVE_TARGETS, and seems unnecessary anyway.
21000 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21001 (Vx_sent_selection_functions): Doc fix.
21003 2011-05-26 Leo Liu <sdl.web@gmail.com>
21005 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21007 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21009 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21011 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21012 for fringe update if it has periodic bitmap.
21013 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21014 and fringe_bitmap_periodic_p.
21016 * fringe.c (get_fringe_bitmap_data): New function.
21017 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21018 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21019 row. Mark glyph row for fringe update if periodicity changed.
21021 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21022 for fringe update unless it has periodic bitmap.
21024 2011-05-25 Kenichi Handa <handa@m17n.org>
21026 * xdisp.c (get_next_display_element): Set correct it->face_id for
21027 a static composition.
21029 2011-05-24 Leo Liu <sdl.web@gmail.com>
21032 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21034 * fns.c (crypto_hash_function, Fsha1): New function.
21035 (Fmd5): Use crypto_hash_function.
21036 (syms_of_fns): Add Ssha1.
21038 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21040 * gnutls.c: Remove unused macros.
21041 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21042 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21043 Remove macros that are defined and never used.
21044 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21046 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21048 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21049 (Fx_get_selection_internal): Minor cleanup.
21050 (Fx_own_selection_internal): Rename arguments for consistency with
21053 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21055 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21057 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21059 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21061 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21063 * dispnew.c (scrolling_window): Don't exclude the case that the
21064 last enabled row in the desired matrix touches the bottom boundary.
21066 2011-05-21 Glenn Morris <rgm@gnu.org>
21068 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21069 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21070 and add some more files.
21072 2011-05-20 Eli Zaretskii <eliz@gnu.org>
21074 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21075 report_file_error introduced by the change from 2011-05-07.
21077 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21079 * systime.h (Time): Define only if emacs is defined.
21080 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21081 where the include path doesn't have X11/X.h by default. See
21082 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21084 2011-05-20 Kenichi Handa <handa@m17n.org>
21086 * composite.c (find_automatic_composition): Fix previous change.
21088 2011-05-20 Glenn Morris <rgm@gnu.org>
21090 * lisp.mk: New file, split from Makefile.in.
21091 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21092 (shortlisp): Remove.
21093 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21095 2011-05-19 Glenn Morris <rgm@gnu.org>
21097 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21098 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21099 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21100 (lisp): Set the order to that of loadup.el.
21101 (shortlisp): Make it a copy of $lisp.
21102 (SOME_MACHINE_LISP): Remove.
21103 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21104 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21106 2011-05-18 Kenichi Handa <handa@m17n.org>
21108 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21109 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21110 (find_automatic_composition): Mostly rewrite for efficiency.
21112 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21114 * makefile.w32-in: Update dependencies.
21116 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21118 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21119 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21121 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21123 Fix some integer overflow issues, such as string length overflow.
21125 * insdel.c (count_size_as_multibyte): Check for string overflow.
21127 * character.c (lisp_string_width): Check for string overflow.
21128 Use EMACS_INT, not int, for string indexes and lengths; in
21129 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21130 the resulting string length overflows an EMACS_INT; instead,
21131 report a string overflow if no precision given. When checking for
21132 precision exhaustion, use a check that cannot possibly have
21133 integer overflow. (Bug#8675)
21134 * character.h (lisp_string_width): Adjust to new signature.
21136 * alloc.c (string_overflow): New function.
21137 (Fmake_string): Use it. This doesn't change behavior, but saves
21138 a few bytes and will simplify future changes.
21139 * character.c (string_escape_byte8): Likewise.
21140 * lisp.h (string_overflow): New decl.
21142 Fixups, following up to the user-interface timestamp change.
21143 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21144 for UI timestamps, instead of unsigned long.
21145 * msdos.c (mouse_get_pos): Likewise.
21146 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21147 * w32gui.h (Time): Define by including "systime.h" rather than by
21148 declaring it ourselves. (Bug#8664)
21150 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21151 * image.c (clear_image_cache): Likewise.
21153 * term.c (term_mouse_position): Don't assume time_t wraparound.
21155 Be more systematic about user-interface timestamps.
21156 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21157 and sometimes 'EMACS_UINT', to represent these timestamps.
21158 This change causes it to use 'Time' uniformly, as that's what X uses.
21159 This makes the code easier to follow, and makes it easier to catch
21160 integer overflow bugs such as Bug#8664.
21161 * frame.c (Fmouse_position, Fmouse_pixel_position):
21162 Use Time, not unsigned long, for user-interface timestamps.
21163 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21164 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21165 * keyboard.h (last_event_timestamp): Likewise.
21166 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21167 * menu.h (xmenu_show): Likewise.
21168 * term.c (term_mouse_position): Likewise.
21169 * termhooks.h (struct input_event.timestamp): Likewise.
21170 (struct terminal.mouse_position_hook): Likewise.
21171 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21172 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21173 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21174 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21175 what it was before.
21176 * menu.h, termhooks.h: Include "systime.h", for Time.
21178 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21179 Don't assume that the difference between two unsigned long values
21180 can fit into an integer. At this point, we know button_down_time
21181 <= event->timestamp, so the difference must be nonnegative, so
21182 there's no need to cast the result if double-click-time is
21183 nonnegative, as it should be; check that it's nonnegative, just in
21184 case. This bug is triggered when events are more than 2**31 ms
21185 apart (about 25 days). (Bug#8664)
21187 * xselect.c (last_event_timestamp): Remove duplicate decl.
21188 (x_own_selection): Remove needless cast to unsigned long.
21190 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21191 that always fit in int. Use a sentinel instead of a counter, to
21192 avoid a temp and to allay GCC's concerns about possible int overflow.
21193 * frame.h (struct frame): Use int for menu_bar_items_used
21194 instead of EMACS_INT, since it always fits in int.
21196 * menu.c (grow_menu_items): Check for int overflow.
21198 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21200 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21201 Before, the code was not consistent. These values cannot exceed
21202 2**31 - 1 so there's no need to make them unsigned.
21203 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21204 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21205 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21207 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21209 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21210 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21211 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21212 presumably because the widths might not match.
21214 * window.c (size_window): Avoid needless test at loop start.
21216 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21218 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21220 2011-05-12 Drew Adams <drew.adams@oracle.com>
21222 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21224 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21226 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21227 `width' to `bar_area_x' and `bar_area_width', respectively.
21228 (x_scroll_run): Take account of fringe background extension.
21230 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21231 Rename local vars `left' and `width' to `bar_area_x' and
21232 `bar_area_width', respectively.
21233 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21234 background extension.
21236 2011-05-10 Jim Meyering <meyering@redhat.com>
21238 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21240 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21242 * image.c (Finit_image_library): Return t for built-in image types,
21243 like pbm and xbm. (Bug#8640)
21245 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21247 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21249 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21251 * w32console.c (Fset_screen_color): Doc fix.
21252 (Fget_screen_color): New function.
21253 (syms_of_ntterm): Defsubr it.
21255 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21256 unlink the temporary file if Fcall_process didn't create it in the
21258 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21259 child process will be redirected to a file specified with `:file'.
21260 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21261 cue to call_process_cleanup not to close that handle.
21263 2011-05-07 Ben Key <bkey76@gmail.com>
21265 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21266 one of two shell specific rules, either bootstrap-temacs-CMD or
21267 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21268 to the previous implementation of the bootstrap-temacs rule.
21269 The bootstrap-temacs-CMD rule is similar to the previous
21270 implementation of the bootstrap-temacs rule except that it
21271 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21274 These changes, along with some changes to nt/configure.bat,
21275 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21276 earlier fix to add support for --cflags and --ldflags options
21277 that include quotes so that it works whether make uses cmd or
21280 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21282 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21283 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21285 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21286 a string. Handle both cases.
21287 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21288 (Fdbus_register_method): Use Qinvalid_function.
21290 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21292 * makefile.w32-in: Update dependencies.
21293 (LISP_H): Add inttypes.h and stdin.h.
21294 (PROCESS_H): Add unistd.h.
21296 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21298 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21299 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21301 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21303 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21305 * term.c (vfatal): Remove stray call to va_end.
21306 It's not needed and the C Standard doesn't allow it here anyway.
21308 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21309 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21311 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21314 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21316 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21318 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21320 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21322 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21324 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21325 * charset.c (Fdefine_charset_internal): Don't initialize
21326 charset.code_space[15]. The value was garbage, on hosts with
21327 32-bit int (Bug#8600).
21329 * lread.c (read_integer): Be more consistent with string-to-number.
21330 Use string_to_number to do the actual conversion; this avoids
21331 rounding errors and fixes some other screwups. Without this fix,
21332 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21333 (digit_to_number): Move earlier, for benefit of read_integer.
21334 Return -1 if the digit is out of range for the base, -2 if it is
21335 not a digit in any supported base. (Bug#8602)
21337 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21339 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21340 to match comment at start of function. This also removes a
21341 GCC warning about overflow in a 32+64-bit port.
21343 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21345 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21346 Reported by Stefan Monnier in
21347 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21348 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21349 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21351 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21352 (EMACS_UINTPTR): Likewise, with uintptr_t.
21354 * lisp.h: Prefer 64-bit EMACS_INT if available.
21355 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21356 on 32-bit hosts that have 64-bit int, so that they can access
21358 However, temporarily disable this change unless the temporary
21359 symbol WIDE_EMACS_INT is defined.
21361 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21363 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21364 This removes an assumption that EMACS_INT and long are the same
21365 width as pointers. The assumption is true for Emacs porting targets
21366 now, but we want to make other targets possible.
21367 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21368 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21369 In the rest of the code, change types of integers that hold casted
21370 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21371 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21372 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21373 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21374 No need to cast type when ORing.
21375 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21376 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21377 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21378 assume EMACS_INT is the same width as char *.
21379 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21380 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21381 Remove no-longer-needed casts.
21382 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21383 (xg_tool_bar_help_callback, xg_make_tool_item):
21384 Use EMACS_INTPTR to hold an integer
21385 that will be cast to void *; this can avoid a GCC warning
21386 if EMACS_INT is not the same width as void *.
21387 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21388 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21389 (current_message_1, set_message_1):
21390 Use a local to convert to proper width without a cast.
21391 * xmenu.c (dialog_selection_callback): Likewise.
21393 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21394 Also, don't assume VALBITS / RAND_BITS is less than 5,
21395 and don't rely on undefined behavior when shifting a 1 left into
21397 * lisp.h (get_random): Change signature to match.
21399 * lread.c (hash_string): Use size_t, not int, for hash computation.
21400 Normally we prefer signed values; but hashing is special, because
21401 it's better to use unsigned division on hash table sizes so that
21402 the remainder is nonnegative. Also, size_t is the natural width
21403 for hashing into memory. The previous code used 'int', which doesn't
21404 retain enough info to hash well into very large tables.
21405 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21407 * dbusbind.c: Don't possibly lose pointer info when converting.
21408 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21409 Use XPNTR rather than XHASH, so that the high-order bits of
21410 the pointer aren't lost when converting through void *.
21412 * eval.c (Fautoload): Don't double-shift a pointer.
21414 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21416 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21418 * gnutls.c (DEF_GNUTLS_FN):
21419 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21421 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21423 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21426 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21428 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21429 New version that can reserve upto 2GB of heap space.
21431 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21433 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21435 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21437 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21438 `gnutls_certificate_set_x509_key_file'.
21440 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21442 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21443 Update dependencies.
21445 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21447 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21448 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21449 Remove unused parameter `fildes'.
21450 * process.c (read_process_output, send_process): Don't pass it.
21452 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21454 Fix previous change: the library cache is defined in w32.c.
21455 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21456 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21458 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21460 Implement dynamic loading of GnuTLS on Windows.
21462 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21463 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21464 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21467 * gnutls.c (Qgnutls_dll): Define.
21468 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21469 (gnutls_*): Declare function pointers.
21470 (init_gnutls_functions): New function to initialize function pointers.

21472 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21473 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21474 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21475 (emacs_gnutls_write, emacs_gnutls_read)
21476 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21477 (Fgnutls_available_p): New function.
21478 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21479 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21480 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21482 * image.c: Include w32.h.
21483 (Vimage_type_cache): Delete.

21485 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21486 (w32_delayed_load): Move to w32.c.
21488 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21490 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21491 (w32_delayed_load): Move from image.c. When loading a library, record
21492 its filename in the :loaded-from property of the library id.
21493 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21494 Initialize and staticpro them.
21495 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21497 * process.c: Include lisp.h before w32.h, not after.
21498 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21499 instead of gnutls_record_check_pending.
21501 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21503 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21505 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21506 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21509 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21511 * xterm.c (x_set_frame_alpha): Do not set property on anything
21512 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21514 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21516 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21518 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21520 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21521 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21530 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21532 * callproc.c: Indentation fixup.
21534 * sysdep.c (wait_for_termination_1): Make static.
21535 (wait_for_termination, interruptible_wait_for_termination):
21536 Move after wait_for_termination_1.
21538 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21540 * sysdep.c (interruptible_wait_for_termination): New function
21541 which is like wait_for_termination, but allows keyboard
21544 * callproc.c (Fcall_process): Add (:file "file") as an option for
21546 (Fcall_process_region): Ditto.
21548 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21550 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21551 rather than `XVECTOR (FOO)->size'.
21553 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21554 inttypes.h, as a gnulib replacement is used if it not available in
21557 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21559 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21560 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21561 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21563 * coding.c (coding_alloc_by_realloc): Error out if destination
21564 will grow beyond MOST_POSITIVE_FIXNUM.
21565 (decode_coding_emacs_mule): Abort if there isn't enough place in
21566 charbuf for the composition carryover bytes. Reserve an extra
21567 space for up to 2 characters produced in a loop.
21568 (decode_coding_iso_2022): Abort if there isn't enough place in
21569 charbuf for the composition carryover bytes.
21571 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21573 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21574 aborting when %lld or %lll format is passed.
21575 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21576 %llo or %llx format is passed. (Bug#8545)
21578 * window.c (window_scroll_line_based): Use a marker instead of
21579 simple variables to record original value of point. (Bug#7952)
21581 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21582 produced by %s or %c overflows available buffer space. (Bug#8545)
21584 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21586 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21587 (SIZE_MAX): Move defn after all includes, as they might #define it.
21589 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21591 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21593 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21595 * keyboard.c (Qdelayed_warnings_hook): Define.
21596 (command_loop_1): Run `delayed-warnings-hook'
21597 if Vdelayed_warnings_list is non-nil.
21598 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21599 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21601 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21603 * doprnt.c (doprnt): Don't return value smaller than the buffer
21604 size if the message was truncated. (Bug#8545).
21606 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21608 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21609 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21611 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21613 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21615 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21617 * makefile.w32-in: Update dependencies.
21619 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21621 Improve `doprnt' and its usage. (Bug#8545)
21622 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21623 `format_end'. Remove support for %l as a conversion specifier.
21624 Don't use xrealloc. Improve diagnostics when the %l size modifier
21625 is used. Update the commentary.
21627 * eval.c (verror): Simplify calculation of size_t.
21629 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21632 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21634 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21637 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21639 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21640 This makes this file independent of the recent pseudovector change.
21642 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21644 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21646 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21647 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21648 Remove unused local.
21649 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21651 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21652 GCC 4.6.0 optimizes based on type-based alias analysis.
21653 For example, if b is of type struct buffer * and v of type struct
21654 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21655 != &v->size, and therefore "v->size = 1; b->size = 2; return
21656 v->size;" must therefore return 1. This assumption is incorrect
21657 for Emacs, since it type-puns struct Lisp_Vector * with many other
21658 types. To fix this problem, this patch adds a new type struct
21659 vectorlike_header that documents the constraints on layout of vectors
21660 and pseudovectors, and helps optimizing compilers not get fooled
21661 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21662 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21663 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21665 (XSETPVECTYPE): Rewrite in terms of new macro.
21666 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21667 This is a bit clearer, and further avoids the possibility of
21668 undesirable aliasing.
21669 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21670 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21671 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21672 since Lisp_Subr is a special case (no "next" field).
21673 (ASIZE): Now uses header.size rather than size.
21674 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21675 to avoid the hassle of writing XVECTOR (foo)->header.size.
21676 (struct vectorlike_header): New type.
21677 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21678 object, to help avoid aliasing.
21679 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21680 (SUBRP): Likewise, since Lisp_Subr is a special case.
21681 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21682 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21683 (struct Lisp_Hash_Table): Combine first two members into a single
21684 struct vectorlike_header member. All uses of "size" and "next" members
21685 changed to be "header.size" and "header.next".
21686 * buffer.h (struct buffer): Likewise.
21687 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21688 * frame.h (struct frame): Likewise.
21689 * process.h (struct Lisp_Process): Likewise.
21690 * termhooks.h (struct terminal): Likewise.
21691 * window.c (struct save_window_data, struct saved_window): Likewise.
21692 * window.h (struct window): Likewise.
21693 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21694 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21695 * buffer.c (init_buffer_once): Likewise.
21696 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21698 * process.c (Fformat_network_address): Use local var for size,
21701 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21703 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21704 * data.c (atof): Remove decl; no longer used or needed.
21705 (digit_to_number): Move to lread.c.
21706 (Fstring_to_number): Use new string_to_number function, to be
21707 consistent with how the Lisp reader treats infinities and NaNs.
21708 Do not assume that floating-point numbers represent EMACS_INT
21709 without losing information; this is not true on most 64-bit hosts.
21710 Avoid double-rounding errors, by insisting on integers when
21711 parsing non-base-10 numbers, as the documentation specifies.
21712 * lisp.h (string_to_number): New decl, replacing ...
21713 (isfloat_string): Remove.
21714 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21715 (read1): Do not accept +. and -. as integers; this
21716 appears to have been a coding error. Similarly, do not accept
21717 strings like +-1e0 as floating point numbers. Do not report
21718 overflow for integer overflows unless the base is not 10 which
21719 means we have no simple and reliable way to continue.
21720 Break out the floating-point parsing into a new
21721 function string_to_number, so that Fstring_to_number parses
21722 floating point numbers consistently with the Lisp reader.
21723 (digit_to_number): Move here from data.c. Make it static inline.
21724 (E_CHAR, EXP_INT): Remove, replacing with ...
21725 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21726 (string_to_number): New function, replacing isfloat_string.
21727 This function checks for valid syntax and produces the resulting
21728 Lisp float number too. Rework it so that string-to-number
21729 no longer mishandles examples like "1.0e+". Use strtoumax,
21730 so that overflow for non-base-10 numbers is reported only when
21731 there's no portable and simple way to convert to floating point.
21733 * textprop.c (set_text_properties_1): Rewrite for clarity,
21734 and to avoid GCC warning about integer overflow.
21736 * intervals.h (struct interval): Use EMACS_INT for members
21737 where EMACS_UINT might cause problems. See
21738 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21739 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21740 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21742 (offset_intervals): Tell GCC not to worry about length overflow
21743 when negating a negative length.
21745 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21746 (overrun_check_free): Likewise.
21748 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21749 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21752 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21753 (gnutls_make_error): Rename local to avoid shadowing.
21754 (gnutls_emacs_global_deinit): ifdef out; not used.
21755 (Fgnutls_boot): Use const for pointer to readonly storage.
21756 Comment out unused local. Fix pointer signedness problems.
21758 * lread.c (openp): Don't stuff size_t into an 'int'.
21759 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21760 about possible signed overflow.
21762 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21763 (GDK_KEY_g): Don't define if already defined.
21764 (xg_prepare_tooltip): Avoid pointer signedness problem.
21765 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21767 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21768 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21770 * xfns.c (Fx_window_property): Simplify a bit,
21771 to make a bit faster and to avoid GCC 4.6.0 warning.
21772 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21774 * fns.c (internal_equal): Don't assume size_t fits in int.
21776 * alloc.c (compact_small_strings): Tighten assertion a little.
21778 Replace pEd with more-general pI, and fix some printf arg casts.
21779 * lisp.h (pI): New macro, generalizing old pEd macro to other
21780 conversion specifiers. For example, use "...%"pI"d..." rather
21781 than "...%"pEd"...".
21782 (pEd): Remove. All uses replaced with similar uses of pI.
21783 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21784 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21785 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21786 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21787 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21788 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21789 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21791 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21792 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21793 * print.c (safe_debug_print, print_object): Likewise.
21794 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21796 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21797 avoiding the 0 flag, which is not portable.
21798 * process.c (Fmake_network_process): Use pI to avoid cast.
21799 * region-cache.c (pp_cache): Likewise.
21800 * xdisp.c (decode_mode_spec): Likewise.
21801 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21802 behavior on 64-bit hosts with printf arg.
21803 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21804 (x_stop_queuing_selection_requests): Likewise.
21805 (x_get_window_property): Don't truncate byte count to an 'int'
21808 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21809 here, since it parses constructs like leading '-' and spaces,
21810 which are not wanted; and it overflows with large numbers.
21811 Instead, simply match F[0-9]+, which is what is wanted anyway.
21813 * alloc.c: Remove unportable assumptions about struct layout.
21814 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21815 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21816 (allocate_vectorlike, make_pure_vector): Use the new macros,
21817 plus offsetof, to remove unportable assumptions about struct layout.
21818 These assumptions hold on all porting targets that I know of, but
21819 they are not guaranteed, they're easy to remove, and removing them
21820 makes further changes easier.
21822 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21823 This doesn't fix a bug but makes the code clearer.
21824 (string_overrun_cookie): Now const. Use initializers that
21825 don't formally overflow signed char, to avoid warnings.
21826 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21827 can cause Emacs to crash when string overrun checking is enabled.
21828 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21829 multiple of sizeof (EMACS_INT); it need not be, if
21830 alignof(EMACS_INT) < sizeof (EMACS_INT).
21831 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21833 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21860 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21862 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21863 "cast to pointer from integer of different size".
21865 Improve doprnt and its use in verror. (Bug#8545)
21866 * doprnt.c (doprnt): Document the set of format control sequences
21867 supported by the function. Use SAFE_ALLOCA instead of always
21870 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21871 is one byte too soon. Don't use xrealloc; instead xfree and
21874 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21876 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21879 * gnutls.c: Renamed global_initialized to
21880 gnutls_global_initialized. Added internals for the
21881 :verify-hostname-error, :verify-error, and :verify-flags
21882 parameters of `gnutls-boot' and documented those parameters in the
21883 docstring. Start callback support.
21884 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21885 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21961 Many local variables are now size_t instead of int or unsigned.
21962 Improve overflow protection. Support `l' modifier for integer
21963 conversions. Support %l conversion. Don't assume an EMACS_INT
21964 argument for integer conversions and for %c.

21983 * callint.c (Fcall_interactively): When displaying error message
21984 about invalid control letter, pass the character's codepoint, not

21989 codepoint of an invalid character, to avoid displaying a bogus
21992 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21993 `error', not SYMBOL_NAME itself.

22071 * dispextern.h (struct redisplay_interface): Rename param
22072 to avoid shadowing.
22073 * termhooks.h (struct terminal): Likewise.

22190 * nsfont.m: Fixed bugs in ns_get_family and
22191 ns_descriptor_to_entity that were caused by using free to
22192 deallocate memory blocks that were allocated by xmalloc (via
22193 xstrdup). This caused Emacs to crash when compiled with
22194 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
22195 --enable-checking=xmallocoverrun). xfree is now used to
22196 deallocate these memory blocks.

22610 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22611 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22612 Remove decls, since these functions are now static.
22613 (Funintern, Fget_internal_run_time): New decls, since these functions
22614 were already external.
22616 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

22623 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22624 Mark functions with DEFUE instead of DEFUN,
22625 if they are used in other modules.
22626 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22627 decls for now-static functions.
22628 * buffer.h (Fdelete_overlay): Remove decl.
22629 * callproc.c (Fgetenv_internal): Mark as internal.

22664 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22666 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22667 when at ZV. (Bug#8487)
22669 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22671 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22673 * keyboard.c (parse_tool_bar_item): Likewise.
22674 * sound.c (sound_cleanup, alsa_close): Likewise.
22675 * termcap.c (tgetent): Likewise.

22677 * xsettings.c (read_and_apply_settings): Likewise.
22679 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22680 (overrun_check_free): Protoize.
22682 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22684 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22685 since callers should never pass a negative size.
22686 Change the signature to match that of plain 'read' and 'write'; see
22687 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22688 * lisp.h: Update prototypes of emacs_write and emacs_read.
22690 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22692 * xdisp.c (redisplay_window): Don't try to determine the character
22693 position of the scroll margin if the window start point w->startp
22694 is outside the buffer's accessible region. (Bug#8468)
22696 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22698 Fix write-region and its subroutines for buffers > 2GB.
22699 * fileio.c (a_write, e_write): Modify declaration of arguments and
22700 local variables to support buffers larger than 2GB.
22701 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22703 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22704 argument, local variables, and return value.
22706 * lisp.h: Update prototypes of emacs_write and emacs_read.
22708 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22710 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22712 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22714 Fix more problems found by GCC 4.6.0's static checks.
22716 * xdisp.c (vmessage): Use a better test for character truncation.
22718 * charset.c (load_charset_map): <, not <=, for optimization,
22719 and to avoid potential problems with integer overflow.
22720 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22721 * casetab.c (set_identity, shuffle): Likewise.
22722 * editfns.c (Fformat): Likewise.
22723 * syntax.c (skip_chars): Likewise.
22725 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22726 This also lets GCC 4.6.0 generate slightly better loop code.
22728 * callint.c (Fcall_interactively): <, not <=, for optimization.
22729 (Fcall_interactively): Count the number of arguments produced,
22730 not the number of arguments given. This is simpler and lets GCC
22731 4.6.0 generate slightly better code.
22733 * ftfont.c: Distingish more carefully between FcChar8 and char.
22734 The previous code passed unsigned char * to a functions like
22735 strlen and xstrcasecmp that expect char *, which does not
22736 conform to the C standard.
22737 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22738 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22739 char * when the C standard requires it.
22741 * keyboard.c (read_char): Remove unused var.
22743 * eval.c: Port to Windows vsnprintf (Bug#8435).
22744 Include <limits.h>.
22745 (SIZE_MAX): Define if the headers do not.
22746 (verror): Do not give up if vsnprintf returns a negative count.
22747 Instead, grow the buffer. This ports to Windows vsnprintf, which
22748 does not conform to C99. Problem reported by Eli Zaretskii.
22749 Also, simplify the allocation scheme, by avoiding the need for
22750 calling realloc, and removing the ALLOCATED variable.
22752 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22754 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22755 But keep the doprint source code for now, as we might revamp it
22756 and use it again (Bug#8435).
22757 * lisp.h (doprnt): Remove.
22758 * Makefile.in (base_obj): Remove doprnt.o.
22759 * deps.mk (doprnt.o): Remove.
22761 error: Print 32- and 64-bit integers portably (Bug#8435).
22762 Without this change, on typical 64-bit hosts error ("...%d...", N)
22763 was used to print both 32- and 64-bit integers N, which relied on
22764 undefined behavior.
22765 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22766 * lisp.h (error, verror): Mark as printf-like functions.
22767 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22768 Report overflow in size calculations when allocating printf buffer.
22769 Do not truncate output string at its first null byte.
22770 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22771 Truncate the output at a character boundary, since vsnprintf does not
22773 * charset.c (check_iso_charset_parameter): Convert internal
22774 character to string before calling 'error', since %c now has the
22776 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22777 overflow when computing char to be passed to 'error'. Do not
22778 pass Lisp_Object to 'error'; pass the integer instead.
22779 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22780 formatted with plain %d.
22782 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22784 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22786 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22788 * xterm.c (x_catch_errors): Remove duplicate declaration.
22790 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22792 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22794 2011-04-10 Jim Meyering <meyering@redhat.com>
22796 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22797 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22798 return ssize_t not "int", and use size_t as the buffer length.
22799 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22800 * gnutls.h: Update declarations.
22801 * process.c (read_process_output): Use ssize_t, to match.
22802 (send_process): Likewise.
22804 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22806 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22808 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22810 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22811 Use unsigned char, to match FcChar8 type definition.
22813 * xterm.c (handle_one_xevent):
22814 * xmenu.c (create_and_show_popup_menu):
22815 * xselect.c (x_decline_selection_request)
22816 (x_reply_selection_request): Avoid type-punned deref of X events.
22818 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22820 Fix some uses of `int' instead of EMACS_INT.
22821 * search.c (string_match_1, fast_string_match)
22822 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22823 (scan_buffer, find_next_newline_no_quit)
22824 (find_before_next_newline, search_command, Freplace_match)
22825 (Fmatch_data): Make some `int' variables be EMACS_INT.
22827 * xdisp.c (display_count_lines): 3rd argument and return value now
22828 EMACS_INT. All callers changed.
22829 (pint2hrstr): Last argument is now EMACS_INT.
22831 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22832 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

22844 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22845 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22847 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22848 (encode_invocation_designation): Last argument P_NCHARS is now
22850 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22851 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22853 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22856 * ccl.c (Fccl_execute_on_string): Declare some variables
22859 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22861 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22863 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22865 * process.c (Fformat_network_address): Doc fix.
22867 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22869 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22871 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22873 * keyboard.c (read_char): Call Lisp function help-form-show,
22874 instead of using internal_with_output_to_temp_buffer.
22875 (Qhelp_form_show): New var.
22876 (syms_of_keyboard): Use DEFSYM macro.
22878 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22880 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22882 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22884 * process.c (Flist_processes): Remove to Lisp.

22889 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22891 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22893 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22895 Fix more problems found by GCC 4.6.0's static checks.

22899 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22901 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22903 * xdisp.c (vmessage): Mark as a printf-like function.
22905 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22907 * sound.c (sound_warning): Don't crash if arg contains a printf format.

22912 to system-supplied API.
22914 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22916 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22917 This avoids several warnings with gcc -Wstrict-overflow.
22918 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22919 directly, rather than having caller test rule sign. This avoids
22920 some unnecessary tests.
22921 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22922 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22923 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22925 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22926 (xfont_open): Avoid unnecessary tests.
22928 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22930 * composite.h, composite.c (composition_gstring_put_cache):
22931 Use EMACS_INT, not int, for length.

22937 by using the new macro.
22939 * textprop.c (set_text_properties_1): Change while to do-while,
22940 since the condition is always true at first.
22942 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22943 (interval_deletion_adjustment): Return unsigned value.
22946 * process.c (list_processes_1, create_pty, read_process_output):

22958 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22959 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22960 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22962 * print.c (print_error_message): Avoid int overflow.
22964 * font.c (font_list_entities): Redo for clarity,
22965 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22967 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22968 (font_score): Avoid potential overflow in diff calculation.
22970 * fns.c (substring_both): Remove var that is set but not used.
22971 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22973 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22975 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22976 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22977 can always succeed if overflow has undefined behavior.
22979 * search.c (boyer_moore, wordify): Remove vars set but not used.
22980 (wordify): Omit three unnecessary tests.
22982 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22983 All callers changed. This avoids the need for an unused var.
22985 * casefiddle.c (casify_region): Remove var that is set but not used.
22987 * dired.c (file_name_completion): Remove var that is set but not used.
22989 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22991 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22992 (Finsert_file_contents): Remove unnecessary code checking fd.
22994 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22995 Check for integer overflow on size calculations.
22997 * buffer.c (Fprevious_overlay_change): Remove var that is set
23000 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23001 Remove vars that are set but not used.
23002 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23003 (timer_check_2): Mark vars as initialized.
23005 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23007 * image.c (lookup_image): Remove var that is set but not used.
23008 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23010 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23011 that are set but not used.
23013 * xfns.c (make_invisible_cursor): Don't return garbage
23014 if XCreateBitmapFromData fails (Bug#8410).
23016 * xselect.c (x_get_local_selection, x_handle_property_notify):
23017 Remove vars that are set but not used.
23019 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23020 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23022 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23023 Remove var that is set but not used.

23025 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23026 Check for overflow.
23028 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23029 (map_tty_color) [!defined MSDOS]: Likewise.
23031 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23033 * coding.c: Remove vars that are set but not used.
23034 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23035 All callers changed.
23036 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23037 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23038 (decode_coding_charset): Remove vars that are set but not used.
23040 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23041 that is set but not used.
23043 * print.c (print_object): Remove var that is set but not used.
23045 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23046 The gnulib version avoids calling malloc in the usual case,
23047 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23048 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23049 * filelock.c (current_lock_owner): Likewise.
23050 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23051 * sysdep.c: Include allocator.h, careadlinkat.h.
23052 (emacs_no_realloc_allocator): New static constant.

23082 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23083 (ns_get_family): Likewise.

23091 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23094 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23096 Add lexical binding.

23107 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23109 (syms_of_lread): Declare `lexical-binding'.
23111 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23113 * keyboard.c (eval_dyn): New fun.
23114 (menu_item_eval_property): Use it.

23118 * fns.c (concat, mapcar1): Accept byte-code-functions.
23120 * eval.c (Fsetq): Handle lexical vars.
23121 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23122 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23123 (FletX, Flet): Obey lexical binding.
23124 (Fcommandp): Handle closures.
23125 (Feval): New `lexical' arg.
23126 (eval_sub): New function extracted from Feval. Use it almost
23127 everywhere where Feval was used. Look up vars in lexical env.
23129 (Ffunctionp): Move from subr.el.
23130 (Ffuncall): Handle closures.
23131 (apply_lambda): Remove `eval_flags'.
23132 (funcall_lambda): Handle closures and new byte-code-functions.
23133 (Fspecial_variable_p): New function.
23134 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23135 but without exporting it to Lisp.
23137 * doc.c (Fdocumentation, store_function_docstring):
23138 * data.c (Finteractive_form): Handle closures.
23140 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23143 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23145 (exec_byte_code): New function extracted from Fbyte_code to handle new
23146 calling convention for byte-code-functions. Add new byte-codes.
23148 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

23154 * xdisp.c (redisplay_internal): Fix prototype.
23156 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23158 * xdisp.c (SCROLL_LIMIT): New macro.
23159 (try_scrolling): Use it when setting scroll_limit.
23160 Limit scrolling to 100 screen lines.
23161 (redisplay_window): Even when falling back on "recentering",
23162 position point in the window according to scroll-conservatively,
23163 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23165 (try_scrolling): When point is above the window, allow searching
23166 as far as scroll_max, or one screenful, to compute vertical
23167 distance from PT to the scroll margin position. This prevents
23168 try_scrolling from unnecessarily failing when
23169 scroll-conservatively is set to a value slightly larger than the
23170 window height. Clean up the case of PT below the margin at bottom
23171 of window: scroll_max can no longer be INT_MAX. When aggressive
23172 scrolling is in use, don't let point enter the opposite scroll
23173 margin as result of the scroll.
23174 (syms_of_xdisp) <scroll-conservatively>: Document the
23175 threshold of 100 lines for never-recentering scrolling.
23177 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

23185 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23187 * indent.c (Fvertical_motion):
23188 * window.c (window_scroll_pixel_based, Frecenter):
23189 Don't pass `need_y_p' to `move_it_by_lines'.
23191 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23193 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23194 steal a few bits to be more compact.
23195 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23196 Remove unneeded casts.
23198 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23200 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23202 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23203 binding" message (bug#7967).
23205 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23207 Fix more problems found by GCC 4.6.0's static checks.
23209 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23210 Remove unused local var.
23212 * editfns.c (Fmessage_box): Remove unused local var.
23214 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23215 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23216 Omit unused local vars.
23217 * window.c (shrink_windows): Omit unused local var.
23218 * menu.c (digest_single_submenu): Omit unused local var.
23219 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23220 Omit unused local var.
23222 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23223 Don't assume string length fits in int.
23224 (keyremap_step, read_key_sequence): Use size_t for sizes.

23227 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23228 instead of alloca (Bug#8344).
23230 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23231 (Fbacktrace_frame): Don't assume nframes fits in int.
23233 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

23240 * cm.c (calccost): Turn while-do into do-while, for clarity.
23242 * keyboard.c (syms_of_keyboard): Use the same style as later
23243 in this function when indexing through an array. This also
23244 works around GCC bug 48267.
23246 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23248 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23250 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23251 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23253 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23254 This avoids undefined behavior on integer overflow, and is a bit
23255 more convenient anyway since it is compared to a size_t variable.
23257 Variadic C functions now count arguments with size_t, not int.
23258 This avoids an unnecessary limitation on 64-bit machines, which
23259 caused (substring ...) to crash on large vectors (Bug#8344).

23269 * fns.c (concat): Likewise.
23270 * frame.c (x_set_frame_parameters): Likewise.
23271 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23272 0 if not found, not -1. All callers changed.
23274 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23275 (stack_copy_size): Now size_t, not int.
23276 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23278 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

23297 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23298 don't set the hook to nil, but remove the offending function instead.
23299 (Qcommand_hook_internal): Remove, unused.
23300 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23301 Vcommand_hook_internal.
23303 * eval.c (enum run_hooks_condition): Remove.
23304 (funcall_nil, funcall_not): New functions.
23305 (run_hook_with_args): Call each function through a `funcall' argument.

23491 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23492 the first time through the loop, since we know p0 < p1 then.
23493 This also avoids a gcc -Wstrict-overflow warning.
23495 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23496 leading to a memory leak, possible in functions like
23497 load_charset_map_from_file that can allocate an unbounded number
23498 of objects (Bug#8318).
23500 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23501 that could (at least in theory) be that large.
23503 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23504 This is less likely to overflow, and avoids undefined behavior if
23505 overflow does occur. All callers changed. Use strtoul to scan
23506 for the unsigned long integer.
23507 (pint2hrstr): Simplify and tune code slightly.
23508 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23510 * scroll.c (do_scrolling): Work around GCC bug 48228.
23511 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
23513 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
23514 This also avoids a warning with gcc -Wstrict-overflow.
23515 (validate_x_resource_name): Simplify count usage.
23516 This also avoids a warning with gcc -Wstrict-overflow.
23518 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23521 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23523 * process.c (Fmake_network_process): Use socklen_t, not int,
23524 where POSIX says socklen_t is required in portable programs.
23525 This fixes a porting bug on hosts like 64-bit HP-UX, where
23526 socklen_t is wider than int (Bug#8277).
23527 (Fmake_network_process, server_accept_connection):
23528 (wait_reading_process_output, read_process_output):
23531 * process.c: Rename or move locals to avoid shadowing.
23532 (list_processes_1, Fmake_network_process):
23533 (read_process_output_error_handler, exec_sentinel_error_handler):
23534 Rename or move locals.
23535 (Fmake_network_process): Define label "retry_connect" only if needed.
23536 (Fnetwork_interface_info): Fix pointer signedness.
23537 (process_send_signal): Add cast to avoid pointer signedness problem.
23538 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
23539 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
23541 Make tparam.h and terminfo.c consistent.
23542 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23543 Include tparam.h instead, since it declares them.
23544 * cm.h (PC): Remove extern decl; tparam.h now does this.
23545 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23546 * terminfo.c: Include tparam.h, to check interfaces.
23547 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23548 (tparam): Adjust signature to match interface in tparam.h;
23549 this removes some undefined behavior. Check that outstring and len
23550 are zero, which they always are with Emacs.
23551 * tparam.h (PC, BC, UP): New extern decls.
23553 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23554 (xftfont_open): Rename locals to avoid shadowing.
23556 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

23558 (OTF_TAG_SYM): Omit macro if not needed.
23559 (ftfont_list): Remove unused local.
23560 (get_adstyle_property, ftfont_pattern_entity):
23561 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):

23566 * xml.c (make_dom): Now static.
23568 * composite.c (composition_compute_stop_pos): Rename local to
23570 (composition_reseat_it): Remove unused locals.
23571 (find_automatic_composition, composition_adjust_point): Likewise.
23572 (composition_update_it): Mark var as initialized.
23573 (find_automatic_composition): Mark vars as initialized,
23574 with a FIXME (Bug#8290).

23577 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23578 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23579 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23580 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23581 to avoid shadowing.
23583 * textprop.c (property_change_between_p): Remove; unused.
23585 * intervals.c (interval_start_pos): Now static.
23587 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23590 Rename locals to avoid shadowing.
23592 * sound.c (wav_play, au_play, Fplay_sound_internal):
23593 Fix pointer signedness.
23594 (alsa_choose_format): Remove unused local var.
23595 (wav_play): Initialize a variable to 0, to prevent undefined
23596 behavior (Bug#8278).
23598 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23600 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23602 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23603 clobbering (Bug#8298).
23604 * sysdep.c (sys_subshell): Likewise.
23605 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23607 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23608 This should get cleaned up, so that child_setup has the
23609 same signature on all platforms.
23611 * callproc.c (call_process_cleanup): Now static.
23612 (relocate_fd): Rename locals to avoid shadowing.
23614 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23616 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23617 not to be necessary, and produces flickering.
23619 2011-03-20 Glenn Morris <rgm@gnu.org>
23621 * config.in: Remove file.
23623 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23625 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23626 are now in src/globals.h.
23627 (syms_of_minibuf): Remove spurious & from previous change.
23629 2011-03-20 Leo Liu <sdl.web@gmail.com>
23631 * minibuf.c (completing-read-function): New variable.
23632 (completing-read-default): Rename from completing-read.
23633 (completing-read): Call completing-read-function.
23635 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23637 * xfaces.c (Fx_load_color_file):
23638 Read color file from absolute filename (bug#8250).
23640 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23642 * makefile.w32-in: Update dependencies.
23644 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23646 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23653 (sigchld_handler): Now static.
23655 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23656 That way, the code declares only the vars that it needs.

23665 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
23666 (CONSTANTLIM): Remove; unused.
23667 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23668 Define only if needed.
23670 * unexelf.c (unexec): Name an expression,
23671 to avoid gcc -Wbad-function-cast warning.
23672 Use a different way to cause a compilation error if anyone uses
23673 n rather than nn, a way that does not involve shadowing.
23674 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23676 * deps.mk (unexalpha.o): Remove; unused.
23678 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23679 * unexec.h: New file.
23680 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23681 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23682 Depend on unexec.h.
23683 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23684 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23685 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23686 Change as necessary to match prototype in unexec.h.

23705 (font_sort_entities): Mark var as initialized.
23707 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
23709 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

23733 * callint.c (quotify_arg, quotify_args): Now static.
23734 (Fcall_interactively): Rename locals to avoid shadowing.
23735 Use const pointer when appropriate.
23737 * lisp.h (get_system_name, get_operating_system_release):

23739 * process.c (get_operating_system_release): Move decl to lisp.h.
23740 * xrdb.c (get_system_name): Likewise.
23741 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23742 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23743 some of which prompt warnings from gcc -Wbad-function-cast.
23744 (Fformat_time_string, Fencode_time, Finsert_char):
23745 (Ftranslate_region_internal, Fformat):
23746 Rename or remove local vars to avoid shadowing.

23771 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23772 (GC_STRING_CHARS): Remove; not used.
23773 (Fmemory_limit): Cast sbrk's returned value to char *.
23775 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23776 avoids undefined behavior in theory.
23778 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23780 Use functions, not macros, for up- and down-casing (Bug#8254).
23781 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23782 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23783 to use the following functions instead of these macros.
23784 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23785 EMACS_INT, since callers assume the returned value fits in int.
23786 (upcase1): Likewise, for UPCASE_TABLE.
23787 (uppercasep, lowercasep, upcase): New static inline functions.
23788 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23789 the race-condition problem in the old DOWNCASE.

23797 which gcc can warn about.
23798 (regex_compile, re_match_2_internal): Mark locals as initialized.
23799 (RETALLOC_IF): Define only if needed.
23800 (WORDCHAR_P): Likewise. This one is never needed, but is used
23801 only in a comment talking about a compiler bug, so put inside
23802 the #if 0 of that comment.
23803 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23804 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23807 * search.c (boyer_moore): Rename locals to avoid shadowing.
23808 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
23809 (PREV_CHAR_BOUNDARY): Likewise.

23821 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23822 Rename locals to avoid shadowing.
23823 (Fvertical_motion): Mark locals as initialized.
23825 * casefiddle.c (casify_object, casify_region): Now static.
23826 (casify_region): Mark local as initialized.
23828 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
23830 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23831 New macros, so that the caller can use some names other than
23832 gcpro1, gcpro2, etc.
23833 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23835 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23836 argument, for consistency with GCPRO2_VAR, etc: it is now the
23837 prefix of the variable, not the variable itself. All uses
23839 * dired.c (directory_files_internal, file_name_completion):
23840 Rename locals to avoid shadowing.
23842 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23843 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23844 dired.c's scmp function, had undefined behavior.
23845 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23846 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23847 * buffer.h: ... to here, because these macros use current_buffer,
23848 and the new implementation with inline functions needs to have
23849 current_buffer in scope now, rather than later when the macros
23851 (downcase, upcase1): New static inline functions.
23852 (DOWNCASE, UPCASE1): Reimplement using these functions.
23853 This avoids undefined behavior in expressions like
23854 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23855 from race conditions in accessing the global variables
23856 case_temp1 and case_temp2.
23857 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23858 * lisp.h (case_temp1, case_temp2): Remove their decls.
23859 * character.h (ASCII_CHAR_P): Move from here ...
23860 * lisp.h: ... to here, so that the inline functions mentioned
23861 above can use them.
23863 * dired.c (directory_files_internal_unwind): Now static.
23865 * fileio.c (file_name_as_directory, directory_file_name):
23866 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23868 (file_name_as_directory): Use const pointers when appropriate.
23869 (Fexpand_file_name): Likewise. In particular, newdir might
23870 point at constant storage, so make it a const pointer.
23871 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23872 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23874 (Fset_file_times, Finsert_file_contents, auto_save_error):
23875 Rename locals to avoid shadowing.

23879 to avoid shadowing.
23881 * marker.c (bytepos_to_charpos): Remove; unused.
23883 * lisp.h (verify_bytepos, count_markers): New decls,
23884 so that gcc does not warn that these functions aren't declared.
23886 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23887 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23888 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23889 (copy_text): Remove unused local var.
23891 * filelock.c (within_one_second): Now static.
23892 (lock_file_1): Rename local to avoid shadowing.
23894 * buffer.c (fix_overlays_before): Mark locals as initialized.
23895 (fix_start_end_in_overlays): Likewise. This function should be
23896 simplified by using pointers-to-pointers, but that's a different
23898 (switch_to_buffer_1): Now static.
23899 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23900 (report_overlay_modification): Rename locals to avoid shadowing.
23902 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23903 Fix pointer signedness issue.
23904 (sys_subshell): Mark local as volatile if checking for lint,
23905 to suppress a gcc -Wclobbered warning that does not seem to be right.
23906 (MAXPATHLEN): Define only if needed.
23908 * process.c (serial_open, serial_configure): Move decls from here ...
23909 * systty.h: ... to here, so that they can be checked.
23911 * fns.c (get_random, seed_random): Move extern decls from here ...
23912 * lisp.h: ... to here, so that they can be checked.
23914 * sysdep.c (reset_io): Now static.
23915 (wait_for_termination_signal): Remove; unused.
23917 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
23918 (copy_keymap_item, append_key, push_text_char_description):
23920 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23921 (DENSE_TABLE_SIZE): Remove; unused.
23922 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23923 (describe_map_tree):
23924 Rename locals to avoid shadowing.
23926 * keyboard.c: Declare functions static if they are not used elsewhere.
23927 (echo_char, echo_dash, cmd_error, top_level_2):
23928 (poll_for_input, handle_async_input): Now static.
23929 (read_char, kbd_buffer_get_event, make_lispy_position):
23930 (make_lispy_event, make_lispy_movement, apply_modifiers):
23931 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
23932 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
23933 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
23934 (read_key_sequence, read_char): Mark locals as initialized.
23935 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
23937 * keyboard.h (make_ctrl_char): New decl.
