520 * xdisp.c (row_for_charpos_p): New function, with code of
521 cursor_row_p, but accepts an additional argument CHARPOS instead
522 of using a hardcoded PT.
523 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
524 (row_containing_pos): Call row_for_charpos_p instead of partially
525 doing the same. Fixes cursor positioning under longlines-mode
526 when longlines-show-effect includes more than one newline, when
527 moving the cursor vertically up.
529 2013-05-08 Juanma Barranquero <lekktu@gmail.com>
531 * makefile.w32-in (ACL_H): New macro.

547 * unexelf.c: Don't assume ElfW (Half) fits in int.
548 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
549 when dealing with ElfW (Half) values, since they can exceed 2**31
550 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
551 (entry_address): Omit unused NUM arg. All uses changed.
553 2013-05-07 Juri Linkov <juri@jurta.org>

582 (x_get_monitor_attributes_fallback): Omit unused locals.
583 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
584 Use double, not float, to avoid mixed-mode floating point arithmetic.

601 (x_get_monitor_attributes_xinerama): New functions.
602 (Fx_display_monitor_attributes_list): New primitive.
603 (syms_of_xfns): Defsubr it.
605 * xterm.h (x_display_info): Add Xatom_net_workarea and
606 Xatom_net_current_desktop.
608 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
609 and dpyinfo->Xatom_net_current_desktop.
611 2013-05-06 Eli Zaretskii <eliz@gnu.org>
613 * xdisp.c (pos_visible_p): Use the special code for finding the
614 beginning of a display property or overlay for any "replacing"
615 display property, not just for display strings. This solves
616 incorrect reporting of position by posn-at-point. (Bug#14241)
618 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
620 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
621 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
622 Verify that ElfW (Half) fits in int.
623 (fatal): Use same signature as lisp.h.
624 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
625 configure and build with -DUNEXELF_DEBUG without worrying about
626 other modules that use DEBUG.
627 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
628 possibly-wide integers now uses it instead of plain fprintf.
629 (entry_address): New function, which avoids problems with 32-bit
630 overflow on 64-bit hosts.
631 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
632 (round_up): Don't assume the remainder fits in int.
633 (find_section): Use bool for boolean. Simplify debug code.
634 (unexec): Don't assume file sizes fit in int or size_t.
635 Omit unnecessary trailing newline in 'fatal' format.
636 Use strerror rather than outputting decimal error number.
637 Remove unused code when emacs is not defined;
638 this file relies on Emacs now.
639 Don't assume e_phnum and e_shnum are positive.
641 * regex.c: Fix problems when DEBUG is defined.
642 (extract_number, extract_number_and_incr): Define regardless of
643 whether DEBUG is defined; that's simpler and makes the code less
644 likely to go stale in the normal case when DEBUG is not defined.
645 Return int rather than taking an int * arg. All callers changed.
646 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
647 Remove, replacing with ...
648 (DEBUG_PRINT): New macro. All callers changed.
649 (DEBUG_COMPILES_ARGUMENTS): New macro.

654 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
655 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
656 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
657 Don't assume ptrdiff_t, size_t, and long are the same width as int.
658 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
659 This matters only when DEBUG is defined.
661 2013-05-05 Eli Zaretskii <eliz@gnu.org>
663 * xdisp.c (set_iterator_to_next): Set the
664 ignore_overlay_strings_at_pos_p flag only if we are _really_
665 iterating over an overlay string, as indicated by the
666 current.overlay_string_index member. (Bug#14306)
668 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
670 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
671 to where it is used, to avoid autorelease issues (Bug#14050).
673 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
675 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
676 * fileio.c (syms_of_fileio): Implement this.
677 * filelock.c (create_lock_file): If symbolic links don't work, so
678 we use a regular file as a lock file, do not fsync the lock file;
681 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>

692 Use parentheses to disambiguate last part of the condition.
694 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
695 assertion violations. (Bug#14062)
697 2013-05-01 David Reitter <david.reitter@gmail.com>
699 * nsfns.m (ns_tooltip): Initialize.
701 2013-04-28 Eli Zaretskii <eliz@gnu.org>

720 * callint.c (Fcall_interactively): Call `Qread_number' for
721 interactive code letter `n' instead of using duplicate code.
724 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
726 * systime.h (make_timeval): Declare as 'const'.
728 2013-04-27 Kenichi Handa <handa@gnu.org>

733 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
735 Port better to AIX (Bug#14258).
736 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,

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

752 * w32fns.c (w32_fullscreen_rect): New function to compute the
753 window rectangle for the given fullscreen mode.
754 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
755 longer tunes the window size. This keeps the window's edges flush
756 with the screen and allows the taskbar to hide itself in fullboth.
758 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
759 window decorations and uses the entire screen.
761 * w32term.h (w32_fullscreen_rect) Add prototype.
762 (struct w32_output): Replace normal_width, normal_height,
763 normal_top, and normal_left members with a single normal_placement

782 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
783 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
784 parentheses where appropriate.
786 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
788 * keyboard.c (timer_start_idle): Remove no-longer-used local.
790 2013-04-14 Eli Zaretskii <eliz@gnu.org>

793 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
794 Mention in the doc string that setting these variables takes
795 effect only after a call to set-window-buffer. (Bug#14200)
797 2013-04-13 Eli Zaretskii <eliz@gnu.org>
799 * indent.c (Fvertical_motion): Don't consider display strings on
800 overlay strings as display strings on the buffer position we
801 started from. This prevents vertical cursor motion from jumping
802 more than one line when there's an overlay string with a display
803 property at end of line.
804 Reported by Karl Chen <Karl.Chen@quarl.org> in
805 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

810 already selected (bug#14191).
812 2013-04-11 Eli Zaretskii <eliz@gnu.org>
814 * window.c (Fwindow_end): Test more flags, including the buffer's
815 last_overlay_modified flag, to determine whether the window's
816 display is really up-to-date. Prevents the function from
817 returning a stale value. (Bug#14170)
818 (Fwindow_line_height): Fix the test for up-to-date-ness of the
821 2013-04-10 Eli Zaretskii <eliz@gnu.org>
823 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
824 garbaged only if it is not already the top frame on its TTY.
825 This prevents flickering due to constant redrawing of TTY frames when
826 there are GUI frames open in the same session. (Bug#13864)
828 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
830 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
831 of marking the idle timers directly.

857 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
860 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
862 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
863 This bug was introduced by my 2013-02-25 change that simplified
864 data_start configuration. Without this change, on GNU/Linux
865 an Emacs configured with --enable-profiling fails immediately
866 due to a profiler signal.
867 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
868 with these flags. On platforms where special flags are needed
869 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.

871 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
873 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

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

1034 * window.h (struct window): Replace hchild, vchild and buffer slots
1035 with the only contents slot. This is possible because each valid
1036 window may have either the child window (in vertical or horizontal
1037 combination) or buffer to display (for the leaf window). Using that,
1038 a lof of operations to traverse and/or change window hierarchies may
1039 be simplified. New member horizontal is used to distinguish between
1040 horizontal and vertical combinations of internal windows.

1062 internal windows has no glyph matrices anyway.
1063 * dispnew.c (clear_window_matrices, showing_window_margins_p)

1069 (sync_window_with_frame_matrix_rows): Enforce live window.
1070 Use contents slot, not buffer, where appropriate.
1071 * frame.c (set_menu_bar_lines_1): Use WINDOW_VERTICAL_COMBINATION_P
1072 and WINDOW_HORIZONTAL_COMBINATION_P.
1073 (make_frame_visible_1): Simplify the loop.
1074 Use contents slot, not buffer, where appropriate.
1075 * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
1076 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1077 (expose_window_tree): Likewise.
1078 Use contents slot, not buffer, where appropriate.
1079 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1080 to avoid deleted windows. Use contents slot instead of buffer.
1081 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
1082 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

1095 Reported by <rzl24ozi@gmail.com>.
1097 2013-03-28 Dmitry Antipov <dmantipov@yandex.ru>

1102 This is needed to ensure that...
1103 (redisplay_window): ...both window markers are valid here,
1104 which is verified by eassert.
1105 * editfns.c (save_excursion_save): Do not assume that
1106 selected_window always displays the buffer.
1107 * buffer.c (Fbuffer_swap_text): Adjust window start markers.

1250 * w32term.c (w32fullscreen_hook): Use FRAME_NORMAL_WIDTH,
1251 FRAME_NORMAL_HEIGHT, and FRAME_PREV_FSMODE, instead of static

1444 (pp_cache): Put under ENABLE_CHECKING.
1446 2013-03-14 Eli Zaretskii <eliz@gnu.org>
1448 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
1449 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
1451 (w32fullscreen_hook): If the frame is visible, reset
1452 f->want_fullscreen flag after changing the frame size. If the
1453 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1456 2013-03-13 Daniel Colascione <dancol@dancol.org>
1458 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1459 too so that these builds can use Cygwin's file conversion
1460 functions. (We've been building and linking cygw32.o all along
1461 and just not using it.)
1463 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1465 File synchronization fixes (Bug#13944).
1466 * Makefile.in (LIB_FDATASYNC): New macro.
1468 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
1469 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
1470 Don't worry about HAVE_FSYNC, since a substitute fsync is
1471 available if the system lacks one.
1472 (Fwrite_regin): Retry fsync if interrupted.
1474 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1476 * w32term.c (w32_read_socket): If the Emacs frame is being
1477 activated, call w32fullscreen_hook, to make sure the new frame
1478 dimensions are in effect. (Bug#13937)
1480 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1482 * xdisp.c (init_iterator): Simplify because both character and byte
1483 positions are either specified or -1. Add eassert. Adjust comment.
1484 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1485 character and byte positions can be obtained from marker.
1487 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1489 Static checking by Sun C 5.12.

1502 a function pointer type; the C Standard requires this.
1504 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1505 Include <sys/param.h> unconditionally, as that works elsewhere and
1506 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1507 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1510 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
1512 * insdel.c (adjust_after_replace): Use bool for boolean.

1539 common file dialog code.
1541 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1542 can just use du like other systems.
1544 * coding.c (from_unicode_buffer): Declare.
1545 * coding.c (from_unicode_buffer): Implement.
1547 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>
1549 * lread.c: Minor cleanup.

1591 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
1593 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1594 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1595 from Elisp via unread-command-events.
1597 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1598 functions to mean "no change".
1600 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1602 region-cache.c, scroll.c, search.c: Use bool for booleans.
1603 * lisp.h (compile_pattern):

1608 (search_regs_saved, Fregexp_quote):
1609 Use bool for boolean.
1610 * region-cache.c (region_cache_forward, region_cache_backward):
1611 Fix comments to match code: these functions return int, not boolean.
1613 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1615 * search.c (find_newline): Accept start and end byte positions
1616 as arguments and allow -1 if not known.
1617 (find_newline_no_quit): Likewise for start position.
1618 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1619 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1620 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1621 * editfns.c (Fconstrain_to_field): Break long line.
1622 Adjust call to find_newline.
1623 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1625 position, where appropriate.
1626 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1627 (get_visually_first_element, move_it_vertically_backward): Likewise.
1628 Obtain byte position from the display iterator, where appropriate.
1630 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1632 print.c, process.c: Use bool for booleans.
1633 * lisp.h (wait_reading_process_output):
1634 * print.c (print_output_debug_flag, PRINTDECLARE, printchar)
1635 (strout, debug_output_compilation_hack, float_to_string, print)

1648 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1650 * bidi.c (bidi_fetch_char): Swap first and second arguments
1651 to match other functions accepting character and byte positions.
1653 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1654 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1655 when you need just to move to the previous buffer position.
1656 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1658 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1671 Adjust comments, style and calls to compute_motion.
1672 (Fvertical_motion): Adjust call to vmotion.
1673 * window.c (Fdelete_other_windows_internal): Record window start
1674 byte position and adjust call to vmotion.
1675 (window_scroll_line_based): Likewise with call to compute_motion.
1677 (Frecenter): Adjust calls to vmotion.
1679 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1681 * lisp.h (list2i, list3i): New functions.
1682 (list4i): Move from window.c and make LISP_INLINE.
1683 * editfns.c (make_lisp_time):
1684 * fns.c (Flocale_info):

1695 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1697 * search.c (find_newline_no_quit): Rename from find_next_newline.
1700 * lisp.h (find_newline_no_quit): Rename prototype.
1702 * xdisp.c (back_to_previous_line_start)

1712 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1714 Coding system support cleanup and minor refactoring.
1715 * coding.h (enum coding_result_code): Remove
1716 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1717 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1718 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1719 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
1720 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.
1721 (decode_coding_region, encode_coding_region, decode_coding_string):

1727 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1728 (decode_coding_object): Simplify since xrealloc never returns NULL.
1731 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1733 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1734 * sysdep.c (list_system_processes)
1735 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1736 Make it a stub in this case; otherwise the build might fail,
1737 and this code hasn't been tested on such hosts anyway.
1738 Problem reported by Nelson H. F. Beebe in
1739 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1740 and analyzed by Jérémie Courrèges-Anglas in
1741 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1743 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1745 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1746 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1747 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1748 * bidi.c (bidi_find_paragraph_start): Likewise.
1749 * indent.c (vmotion): Likewise.
1751 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1753 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1754 * filelock.c: Include <c-ctype.h>.
1755 (MAX_LFINFO): New top-level constant.
1756 (lock_info_type): Remove members pid, boot_time. Add members at,
1757 dot, colon. Change user member to be the entire buffer, not a
1758 pointer. This allows us to handle the case where a foreign
1759 pid or boot time exceeds the local range. All uses changed.
1760 (LINKS_MIGHT_NOT_WORK): New constant.
1761 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1762 (defined_WINDOWSNT): Remove.
1763 (MAKE_LOCK_NAME, file_in_lock_file_name):
1764 Always use .#FILE (not .#-FILE) for the file lock,
1765 even if it is a regular file.
1766 (rename_lock_file): New function.
1767 (create_lock_file): Use it.
1768 (create_lock_file, read_lock_data):
1769 Prefer a symbolic link for the lock file, falling back on a
1770 regular file if symlinks don't work. Do not try to create
1771 symlinks on MS-Windows, due to security hassles. Stick with
1772 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1773 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1774 host may be using a Windowsish file system, and cannot use
1775 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1776 doesn't work. Don't fail merely because of a symlink-contents
1777 length limit in the current file system; fall back on regular
1778 files. Increase the symlink contents length limit to 8 KiB, this
1779 should be big enough for any real use and doesn't crunch the
1781 (create_lock_file, lock_file_1, read_lock_data):
1782 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1783 (lock_file_1): Return error number, not bool. All callers changed.
1784 (ELOOP): New macro, if not already defined.
1785 (read_lock_data): Return size of lock file contents, not Lisp object.
1786 All callers changed. Handle a race condition if some other process
1787 replaces a regular-file lock with a symlink lock or vice versa,
1788 while we're trying to read the lock.
1789 (current_lock_owner): Parse contents more carefully, to help avoid
1790 confusing a regular-file lock with some other application's use
1791 of the file. Check for lock file contents being too long, or
1792 not parsing correctly.
1793 (current_lock_owner, lock_file):
1794 Allow foreign pid and boot times that exceed the local range.
1795 (current_lock_owner, lock_if_free, lock_file):
1796 Simplify allocation of lock file contents.
1797 * w32.c (sys_rename_replace): New function, containing most of
1798 the contents of the old sys_rename.
1799 (sys_rename): Use it.
1800 (fchmod): New dummy function.
1801 * w32.h (sys_rename_replace, fchmod): New decls.
1803 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1805 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1806 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1807 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1808 <dmantipov@yandex.ru>.
1810 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1812 * composite.c (get_composition_id, fill_gstring_header):
1813 Use make_uninit_vector where appropriate.
1814 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1815 * xselect.c (clean_local_selection_data): Likewise.
1817 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1819 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1820 * image.c (imagemagick_load_image): Calculate height and width
1821 after flattening the image, not before.
1823 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1825 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1826 * ftfont.c (ftfont_shape_by_flt): Likewise.
1827 * w32uniscribe.c (uniscribe_shape): Likewise.
1829 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1831 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1832 The old approach, which fell back on DIR/.#FILE.0 through
1833 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1834 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1835 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1836 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1837 because the locking mechanism was never reliable in that case).
1838 This patch fixes this and other bugs discovered by a code
1839 inspection that was prompted by
1840 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1841 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1842 to avoid interoperability problems between the MS-Windows and
1843 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1844 instances of Emacs now ignore each others' locks.
1845 * filelock.c (defined_WINDOWSNT): New constant.
1846 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1847 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1848 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1849 regular files on MS-Windows hosts.
1850 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1851 Use SAFE_ALLOCA to avoid problems with long file names.
1852 (MAX_LFINFO): Now a local constant, not a global macro.
1853 (IS_LOCK_FILE): Remove.
1854 (lock_file_1): Don't inspect errno if symlink call succeeds;
1855 that's not portable.
1856 (lock_file): Document that this function can return if lock
1858 (lock_file): Don't access freed storage.
1860 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1862 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1864 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1866 * textprop.c: Use bool for booleans.
1867 (validate_interval_range, Fadd_text_properties)
1868 (Fremove_text_properties): Prefer bool to int when either works.
1870 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1872 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1873 If the interval tree changes as a side effect of calling
1874 modify_region, re-do processing starting from the call to
1875 validate_interval_range. (Bug#13743)
1877 2013-02-28 Eli Zaretskii <eliz@gnu.org>

1882 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1884 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1885 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1886 access to the lock file until it is written and closed.
1889 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1891 * callint.c (Qcall_interactively):

1901 Minor textprop integer cleanup.
1902 * intervals.h, textprop.c (add_text_properties_from_list):
1903 Return void, not int, since nobody uses the return value.
1904 * textprop.c (validate_plist, add_properties, remove_properties)
1905 (Fadd_text_properties):
1906 Don't assume list length fits in int.
1907 (interval_has_all_properties, interval_has_some_properties)
1908 (interval_has_some_properties_list, add_properties, remove_properties)

1918 Implement CLASH_DETECTION for MS-Windows.
1920 * filelock.c [WINDOWSNT]: Include w32.h.

1922 function of that name. Up-case the macro arguments.
1923 (IS_LOCK_FILE): New macro.
1924 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.

1928 the lock information as its contents.
1929 (read_lock_data): New function, on Posix platforms just calls
1931 [WINDOWSNT]: Read the lock info from the file.
1932 (current_lock_owner): Call read_lock_data instead of calling
1933 emacs_readlinkat directly.
1934 (lock_file) [WINDOWSNT]: Run the file name through
1937 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1938 just check if the process by that PID exists.
1940 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1941 also present, as doing so will fail to error out if the file
1944 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1946 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1947 (Fremove_list_of_text_properties): Skip all of the intervals in
1948 the region between START and END that already have resp. don't
1949 have the requested properties, not just the first one.
1950 Add assertions that the loop afterwards always modifies the
1951 properties. (Bug#13743)
1953 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1955 * callint.c (Fcall_interactively): Use the right lexical environment

1964 (START_FILES): Remove. All uses removed.
1965 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1966 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1967 (buildobj.h): Use it.

1969 (temacs$(EXEEXT)): Use $(ALLOBJS).
1970 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1971 * deps.mk (vm-limit.o):
1972 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1973 Do not depend on mem-limits.h.

1981 * vm-limit.c: Move most of mem-limits.h's contents here.
1982 (data_start): New decl. It's OK if this is approximate,
1983 so simplify-away some unnecessary exactness.
1984 (POINTER): Remove; all uses removed.
1985 (data_space_start): Now char *, to avoid casts.
1986 (exceeds_lisp_ptr): New function, replacing the old
1987 EXCEEDS_LISP_PTR macro. All uses changed.

2003 and diagnosed by Andreas Schwab in
2004 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
2006 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2008 Assume C89 or better.
2009 * ralloc.c (SIZE, POINTER, NIL):
2010 * vm-limit.c (POINTER):
2011 Remove, replacing all uses with C89 equivalents. These old
2012 symbols were present only for porting to pre-C89 platforms.
2014 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
2016 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
2017 This avoids warning messages reported as part of Bug#13546.
2019 2013-02-21 Ken Brown <kbrown@cornell.edu>
2021 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
2023 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
2025 * sheap.c (report_sheap_usage): Prefer message1_nolog.

2032 2013-02-19 Daniel Colascione <dancol@dancol.org>
2034 * sheap.c (report_sheap_usage): Use message, not message1, so
2035 that we don't try to create a buffer while we're in the middle
2036 of dumping Emacs. Explain why.
2038 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2040 * search.c (find_newline): Return byte position in bytepos.

2050 (get_visually_first_element, move_it_vertically_backward):
2051 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
2053 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2055 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2056 resources were not orderly released.
2058 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2060 * xdisp.c (x_draw_vertical_border): For a window that is neither
2061 the leftmost nor the rightmost, redraw both the left and the right
2062 vertical borders. (Bug#13723)
2064 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

2073 * editfns.c (Fmessage, Fmessage_box):
2074 * callint.c (Fcall_interactively):
2075 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.

2084 * w32.c (sys_chown): Remove unused function.
2086 * w32term.c <input_signal_count>: Declare 'volatile'
2087 unconditionally. (Bug#9066)
2089 * w32.c (set_errno): Reset h_errno and don't set it to any other
2090 value. Set errno instead.
2091 (check_errno): Reset h_errno.
2092 (sys_socket, socket_to_fd, sys_bind, sys_connect)
2093 (sys_gethostname, sys_getservbyname, sys_getpeername)
2094 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2095 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
2097 (sys_gethostbyname): Set h_errno only errors detected.
2099 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2101 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
2103 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2105 * keyboard.c (read_char): Fix calculation of auto-save time out
2106 when auto-save-timeout is less than 4. (Bug#13720)
2108 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
2109 time. Improve diagnostics in DebPrint. (Bug#13546)

2112 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
2113 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2114 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
2115 make sure errno is set to an appropriate value. (Bug#13546)
2116 (socket_to_fd): Add assertion against indexing fd_info[] with a
2117 value that is out of bounds.
2118 (sys_accept): If fd is negative, do not set up the child_process
2119 structure for reading.
2121 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
2123 * composite.c (fill_gstring_header): Remove useless prototype.

2130 (get_overlay_arrow_glyph_row, display_mode_element):
2131 (decode_mode_spec_coding, message3):
2132 * xfaces.c (face_at_string_position): Use bool for booleans.
2135 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2137 Fix AIX port (Bug#13650).
2138 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2139 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2140 was #undeffed earlier, so it cannot be used as a macro here.
2141 Use the constant and not the macro.
2143 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2145 * w32proc.c (new_child): If no vacant slots are found in
2146 child_procs[], make another pass looking for slots whose process
2147 has exited or died. (Bug#13546)
2149 * w32.c (sys_pipe): When failing due to file descriptors above
2150 MAXDESC, set errno to EMFILE.
2151 (_sys_read_ahead): Update cp->status when failing to read serial
2152 communications input, so that the status doesn't stay at
2153 STATUS_READ_IN_PROGRESS. (Bug#13546)
2155 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2157 * gtkutil.c (tb_size_cb): New function.
2158 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2160 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2162 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2165 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2167 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2169 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
2171 * font.c (font_range): Add pos_byte argument. Adjust comment
2172 and break long line.
2173 * font.h (font_range): Adjust prototype.
2174 * composite.c (autocmp_chars): Pass byte position to font_range.
2175 Break long line. Remove useless prototype and format comment.
2177 2013-02-13 Glenn Morris <rgm@gnu.org>
2179 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2181 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2183 Improve AIX port some more (Bug#13650).
2184 With this, it should be as good as it was in 23.3, though it's
2185 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2186 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2187 * unexaix.c (start_of_text): Remove.
2188 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2189 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2190 (orig_load_scnptr, orig_data_scnptr):
2191 Now off_t, not long, since they are file offsets.
2192 (make_hdr): Use _data, not start_of_data ().
2193 This is the key part of the fix.
2194 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2195 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2197 * pre-crt0.c (data_start): Initialize to 1.
2198 This ports to compilers that optimize the external declaration
2199 'int x = 0;' as if it were 'int x;' to shrink the executable.
2201 Improve AIX port (Bug#13650).
2202 This doesn't fix the bug, but it makes progress: Emacs builds now.
2203 * unexaix.c: Include inttypes.h, stdarg.h.
2204 (report_error, report_error_1): Mark as _Noreturn.
2205 (report_error): Don't report the wrong errno.
2206 (report_error_1): Now varargs. All callers changed.
2207 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2208 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2209 (write_ptr): Use %p to print address rather than %lx and a cast
2210 to unsigned long. Grow buffer a bit, to be safer.
2212 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2214 * bidi.c (bidi_resolve_neutral): After finding the next
2215 non-neutral character, accept NEUTRAL_ON type as well, because
2216 directional control characters, such as LRE and RLE, have their
2217 type converted to that by bidi_resolve_weak. This avoids aborts
2218 when LRE/RLE follows a run of neutrals.
2219 (bidi_move_to_visually_next): Assert that return value of
2220 bidi_peek_at_next_level is non-negative. Negative values will
2223 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2225 Minor getenv-related fixes.
2226 * callproc.c (Fcall_process_region) [!DOS_NT]:
2227 Avoid unnecessary duplicate call to getenv.
2228 * callproc.c (init_callproc):
2229 * dispnew.c (init_display):
2230 * sysdep.c (sys_subshell):
2231 Omit unnecessary cast of getenv or egetenv.
2233 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2235 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2236 Update dependencies.
2238 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2240 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2242 (display_line): Set w->region_showing to the value of
2243 it->region_beg_charpos, not to -1. This fixes redisplay
2244 optimization when cursor is moved up after M->. (Bug#13623)
2246 (try_scrolling): Scroll text up more if point is too close to ZV
2247 and inside the scroll margin. This makes sure point is moved
2248 outside the scroll margin in these cases.
2250 * window.h (struct window): region_showing can no longer be
2253 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2255 Tune by using memchr and memrchr.
2256 * doc.c (Fsnarf_documentation):
2257 * fileio.c (Fsubstitute_in_file_name):
2258 * search.c (find_newline, scan_newline):
2259 * xdisp.c (pos_visible_p, display_count_lines):
2260 Use memchr and memrchr rather than scanning byte-by-byte.
2261 * search.c (find_newline): Rename from scan_buffer.
2262 Omit first arg TARGET, as it's always '\n'. All callers changed.
2264 Clean up read_key_sequence a tiny bit more.
2265 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2266 (read_key_sequence): Remove unused locals.
2268 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2270 Clean up read_key_sequence a bit; reread active keymaps after first event.
2271 * keyboard.c (read_char, read_char_x_menu_prompt)
2272 (read_char_minibuf_menu_prompt):
2273 Replace nmaps+maps with a single `map' arg.
2274 (follow_key): Operate on a single map.
2275 (active_maps): New function.
2276 (test_undefined): Also return true for nil bindings.
2277 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2278 a single (composed) keymap. Remember `first_event' to choose the right
2279 set of active keymaps. Recompute the set of keymaps after receiving
2280 the first event. Remove GOBBLE_FIRST_EVENT.
2281 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2282 * keyboard.h (read_char): Update declaration.
2283 * lread.c (read_filtered_event): Adjust call to read_char.
2285 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2287 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2288 Don't use the limitation on backwards movement when lines are truncated
2289 in the window. (Bug#13675)
2291 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2293 * marker.c (set_marker_internal): If desired position is passed
2294 as a marker, avoid call to buf_charpos_to_bytepos.
2295 * window.c (Fset_window_point): Omit redundant type checking.
2296 (Fset_window_start): Likewise. Format comment.
2297 (window_scroll_pixel_based): Use set_marker_restricted_both
2298 with character and byte positions obtained from an iterator.
2299 (Fset_window_configuration): Use set_marker_restricted_both.
2300 * xdisp.c (message_dolog): Likewise.
2302 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2304 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2305 When text lines are longer than window's screen lines, don't move back
2306 too far. This speeds up some redisplay operations. (Bug#13675)
2308 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2310 * syntax.c (scan_sexps_forward): Fix byte position calculation
2311 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2313 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2315 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2316 that was not needed.
2318 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2320 Minor hashing refactoring.
2321 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2322 (sxhash_float): Return EMACS_UINT, for consistency with the other
2324 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2325 non-static inline function and therefore can't use static vars.
2326 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2327 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2328 with the other hash functions.
2330 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2332 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2333 XXXXXX part of the temporary file pattern is not downcased even
2334 when w32-downcase-file-names is non-nil. (Bug#13661)
2336 * xdisp.c (decode_mode_spec): Remove handling of %t.
2338 * msdos.c (careadlinkatcwd): Remove.
2340 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2342 * lread.c (skip_dyn_bytes): New function (bug#12598).
2343 (read1): Use it. Use getc instead of READCHAR to read bytes.
2344 (load_each_byte): Remove. Update users.
2346 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2348 * search.c (scan_buffer): Calculate end byte position just once.

2352 (scan_sexps_forward): Record from_byte and avoid redundant
2353 character to byte position calculation ...
2354 (Fparse_partial_sexp): ... here. Break too long line.
2356 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2358 * lisp.h (make_uninit_vector): New function.
2359 * alloc.c (Fvector, Fmake_byte_code):

2378 argument is known to be a vector.
2379 * fns.c (Flocale_info): Likewise for ASET.
2380 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2381 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2383 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2385 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2388 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2389 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and

2392 * nsterm.m (NEW_STYLE_FS): Remove.
2393 (ns_last_use_native_fullscreen): New variable.
2394 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2395 (x_set_window_size): Do not take title bar and tool bar into account
2396 if isFullscreen returns YES.
2397 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2398 (check_native_fs): New function.

2415 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2416 (syms_of_nsterm): Add ns-use-native-fullscreen.
2418 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2420 * fileio.c (Qchoose_write_coding_system): Now static.
2422 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2424 * xdisp.c (window_buffer_changed): region_showing can be negative,
2425 which still means region is being displayed.
2426 (redisplay_internal): Resurrect code that forced redisplay of the
2427 whole window when showing region and the mark has changed.
2428 Record the new mark position to allow redisplay optimizations.
2429 (display_line): If it->region_beg_charpos is non-zero, set the
2430 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2432 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2433 not bitfield of 1 bit.
2435 2013-02-03 Daniel Colascione <dancol@dancol.org>
2437 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2438 daemon mode works on cygw32 when Emacs is installed and not just
2441 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2443 Avoid file time stamp bug on MS-Windows (Bug#13149).
2444 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2445 as FAT32 doesn't update time stamps when truncating them.
2446 Also, check that a file time stamp is not a multiple of 100 ns;
2447 this should catch all instances of the problem on MS-Windows,
2448 as its native file system resolution is 100 ns or worse, and
2449 checking for a non-multiple of 100 ns should impose only a small
2450 overhead on systems with ns resolution.
2452 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2454 Avoid encoding file names on MS-Windows when they need to be run
2455 through dostounix_filename.
2456 * w32.c (normalize_filename): Accept an additional argument
2457 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2458 downcase it even if w32-downcase-file-names is non-nil.
2459 (dostounix_filename): Accept an additional argument MULTIBYTE and
2460 pass it to normalize_filename.
2461 (emacs_root_dir): Adjust.
2463 * msdos.h (dostounix_filename): Adjust prototype.
2465 * w32.h (dostounix_filename): Adjust prototype.
2467 * msdos.c (dostounix_filename): Accept an additional argument and
2469 (init_environment): Adjust callers of dostounix_filename.
2471 * fileio.c (Ffile_name_directory, file_name_as_directory)
2472 (directory_file_name, Fexpand_file_name)
2473 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2475 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2477 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2478 variables, as egetenv is case-insensitive for DOS_NT.
2480 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2481 with an encoded file name.
2483 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2484 Adjust calls to dostounix_filename.
2486 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2488 * unexw32.c (unexec): Adjust call to dostounix_filename.
2490 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2492 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2495 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2498 * callproc.c (Fcall_process): Make sure program name in PATH and
2499 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2500 is passed to exec/spawnve, which fails unless the file-name
2503 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2504 even if w32-quote-process-args is nil.
2506 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2508 Fix timestamp bug when write-region appends nothing (Bug#13149).
2509 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2510 the file's time stamp doesn't change if Emacs happens to write nothing
2511 to the file, and on a buggy file system this could cause Emacs to
2512 incorrectly infer that the file system doesn't have the bug.
2513 Avoid this problem by inhibiting the inference in this case.
2515 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2517 * window.h (struct window): Convert base_line_number, base_line_pos
2518 and column_number_displayed members from Lisp_Object to ptrdiff_t.

2522 (make_window): Initialize column_number_displayed.
2523 * print.c (print_object): Follow the printed representation of
2524 frames and print window pointer to distinguish between windows.

2526 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2527 (wset_column_number_displayed, wset_region_showing): Remove.
2528 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2529 (try_scrolling, try_cursor_movement, redisplay_window)
2530 (try_window_reusing_current_matrix, try_window_id, display_line)
2531 (display_mode_lines, decode_mode_spec): Adjust users.
2532 * .gdbinit (pwinx): Do not print sequence_number.
2534 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2536 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2537 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2538 * dired.c: Include <fcntl.h>.
2539 (open_directory): New function, which uses open and fdopendir
2540 rather than opendir. DOS_NT platforms still use opendir, though.
2541 (directory_files_internal, file_name_completion): Use it.
2542 (file_attributes): New function, with most of the old Ffile_attributes.
2543 (directory_files_internal, Ffile_attributes): Use it.
2544 (file_attributes, file_name_completion_stat): First arg is now fd,
2545 not dir name. All uses changed. Use fstatat rather than lstat +
2547 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2548 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2549 (emacs_readlinkat): New function, with much of the old
2550 Ffile_symlink_p, but with an fd argument for speed.
2551 It uses readlinkat rather than careadlinkatcwd, so that it
2552 need not assume the working directory.
2553 (Ffile_symlink_p): Use it.
2554 * filelock.c (current_lock_owner): Use emacs_readlinkat
2555 rather than emacs_readlink.
2556 * lisp.h (emacs_readlinkat): New decl.
2557 (READLINK_BUFSIZE, emacs_readlink): Remove.
2558 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2559 (emacs_norealloc_allocator, emacs_readlink): Remove.
2560 This stuff is moved to fileio.c.
2561 * w32.c (fstatat, readlinkat): New functions.
2562 (careadlinkat): Don't check that fd == AT_FDCWD.
2563 (careadlinkatcwd): Remove; no longer needed.
2565 2013-01-31 Glenn Morris <rgm@gnu.org>
2567 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2568 (Fwrite_region): Update for new choose_write_coding_system args.
2569 Move the last piece of choose_write_coding_system here. (Bug#13522)
2570 (syms_of_fileio): Add choose-write-coding-system.
2572 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2574 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2575 (sys_close): Zero out the flags for the file descriptor before
2576 closing it. (Bug#13546)
2578 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2579 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2580 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2583 * w32.c (w32_get_long_filename, init_environment, readlink):
2584 Support file names encoded in DBCS codepages.
2585 (readlink): Use the current file-name-coding-system, not the ANSI
2586 codepage, to decode and handle targets of symlinks.
2588 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2590 * w32.c (opendir): Now accepts a 'const char *'.
2592 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2594 Remove obsolete redisplay code. See the discussion at
2595 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2596 * dispnew.c (preemption_period, preemption_next_check): Remove.
2597 (Vredisplay_preemption_period): Likewise.
2598 (update_frame, update_single_window, update_window, update_frame_1):
2599 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2600 used, following the 2012-06-22 change.
2602 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2604 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2606 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2608 * font.c (num_fonts): Remove the leftover from old
2609 debugging code. Adjust comment style here and there.
2610 * insdel.c (insert_1): Remove.
2611 * lisp.h (insert_1): Remove prototype.
2612 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2614 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2616 * w32.c (max_filename_mbslen): New function.
2617 (normalize_filename, readdir): Use it to detect locales where ANSI
2618 encoding of file names uses a double-byte character set (DBCS).
2619 If a DBCS encoding is used, advance by characters using
2620 CharNextExA, instead of incrementing a 'char *' pointer.
2621 Use _mbslwr instead of _strlwr. (Bug#13515)
2623 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2624 request of memory reservation to 1.7GB. (Bug#13065)
2626 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2628 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2629 at check_extra_latin label. (Bug#13505)
2631 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2633 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2634 Avoid redundant calls to strlen.
2636 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2638 Drop async_visible and async_iconified fields of struct frame.
2639 This is possible because async input is gone; for details, see
2640 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2641 * frame.h (struct frame): Remove async_visible and async_iconified
2642 members, convert garbaged to unsigned bitfield. Adjust comments.
2643 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2644 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2645 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2646 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2647 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2649 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2650 properly. Likewise for obscured.
2652 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2655 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2657 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2659 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2660 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2662 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2664 * xdisp.c (message2, message2_nolog): Remove functions.
2665 (message3, message3_nolog): Extract nbytes and multibyteness directly
2666 from the string. Change all callers.
2667 (message3_nolog): Don't set message_enable_multibyte since set_message
2668 will reset it anyway.
2669 (message1, message1_nolog): Use message3.
2670 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2671 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2672 (set_message): Drop all but the second arg, which has to be a string.
2673 (set_message_1): Simplify now that we know that a1 is NULL and the
2674 second arg is a string.
2675 * frame.h (struct frame): Remove `message_buf' field.
2676 Use glyphs_initialized_p instead.
2677 (FRAME_MESSAGE_BUF): Remove macro.

2679 * lisp.h (message2, message2_nolog): Remove declarations.
2680 (message3, message3_nolog): Update declarations.
2681 * keyboard.c (read_char_minibuf_menu_text)
2682 (read_char_minibuf_menu_width): Remove vars.
2683 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2684 to correctly handle multibyte strings.
2685 * frame.c (delete_frame): Don't free message_buf any more.
2686 * editfns.c (message_text, message_length): Remove vars.
2687 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2688 * fileio.c (auto_save_error): Use message3 instead of message2.
2689 * dispnew.c (adjust_frame_message_buffer): Remove function.
2691 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2693 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2694 real estate used for the tool bar and the menu bar.
2696 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2698 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2699 hidden buffer is prepared to modification (Bug#13164).
2701 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2703 * window.h (struct window): Change window_end_valid member from
2704 Lisp_Object to a bitfield. Adjust comments.
2705 (wset_window_end_valid): Remove.
2706 * window.c (adjust_window_count): Clear window_end_valid.
2707 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2708 (Fwindow_line_height, set_window_buffer, Frecenter)
2709 (Fsplit_window_internal, Fdelete_other_windows_internal)
2710 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2711 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2712 * xdisp.c (check_window_end, reconsider_clip_changes)
2713 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2714 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2715 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2717 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2719 * xdisp.c (mark_window_display_accurate): Simplify the loop
2720 assuming that the only one of vchild, hchild or buffer window
2721 slots is non-nil. Call mark_window_display_accurate_1 for
2722 the leaf windows only.
2723 (mark_window_display_accurate_1): Always assume leaf window.
2726 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2728 * emacs.c (Qkill_emacs_hook): Now static.
2730 * fileio.c (Finsert_file_contents): Simplify.
2731 Remove unnecessary assignments and tests.
2733 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2735 * w32.c (acl_set_file): Don't test for errors unless
2736 set_file_security returns FALSE. Avoids spurious errors when
2739 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2741 * fileio.c (Finsert_file_contents): Revert code introduced at
2742 2013-01-18 in favor of the simpler and generally better fix.
2743 Save stack space by removing 'buffer' and reusing 'read_buf'
2746 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2748 * lisp.h (eabs): Define unconditionally (Bug#13419).
2749 The old "#if !defined (eabs)" was an unnecessary revenant of back
2750 when this macro was called "abs". Document 'eabs' better.
2752 2013-01-19 Glenn Morris <rgm@gnu.org>
2754 * fns.c (Frandom): Doc fix.
2756 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2758 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2759 segfault when there are lots of overlays.
2761 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2762 when there are lots of overlays.
2763 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2764 for the details and a way to reproduce.
2766 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2768 * fileio.c: Use O_APPEND to append.
2769 This corresponds better to the natural interpretation of "append",
2770 and avoids the need to open the output file twice, or to invoke
2771 lseek when APPEND is neither nil nor a number.
2772 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2773 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2774 file possibly twice, and lseeking to its end; this avoids the
2775 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2776 at the same time: the combination is never needed and apparently
2777 it doesn't work with DOS_NT.
2779 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2780 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2782 Allow floating-point file offsets.
2783 Problem reported by Vitalie Spinu in
2784 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2785 * fileio.c (emacs_lseek): Remove.
2786 (file_offset): New function.
2787 (Finsert_file_contents, Fwrite_region): Use it.
2789 2013-01-19 Chong Yidong <cyd@gnu.org>
2791 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid

2794 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2796 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2797 set_file_security as failure due to insufficient privileges.

2801 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2803 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2804 The bug was observed on Ubuntu operating inside a virtual machine,
2805 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2806 The workaround introduces a race condition on non-buggy hosts,
2807 but it's an unlikely race and anyway there's a nearly identical
2808 nearby race that can't be fixed.
2809 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2811 (Fwrite_region): Test for file system time stamp bug.

2825 Free Lisp_Save_Value object used to pass parameters.
2826 (read_non_regular_quit): Rename to read_contents_quit.
2827 (Finsert_file_contents): Redesign internal file reading loop to adjust
2828 gap and end positions after each read and so help make_gap to work
2829 properly. Do not signal an I/O error too early and so do not leave
2830 not yet decoded characters in a buffer, which was the reason of
2831 redisplay crash. Use list2 to build return value. Adjust comments.
2833 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2835 Close a race when statting and reading files (Bug#13149).
2836 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2837 This avoids a race if the file is renamed between stat and open.
2838 This race is not the problem originally noted in Bug#13149;
2839 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

2938 * editfns.c (save_excursion_save): Pack everything within
2939 Lisp_Save_Value and so avoid xmalloc.
2940 (save_excursion_restore): Adjust to match new layout. Use free_misc
2941 because we do not allocate extra memory any more. Add eassert.

3248 only if it's really needed.
3249 * frame.h (enum output_method): Remove output_mac member since
3250 it's a leftover from the deleted code.
3251 * frame.c (Fframep): Adjust user here ...
3252 * terminal.c (Fterminal_live_p): ... and here.
3253 * coding.c (Qmac): Now here because it's only used to denote
3254 end-of-line encoding type.
3255 (syms_of_coding): DEFSYM it.
3256 * frame.h (Qmac): Remove duplicated declaration.
3258 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3260 * window.c (select_window_1): Now static, since it's used only here.
3262 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3264 * window.c (window_body_cols): Subtract display margins from the
3265 window body width on TTYs as well. See
3266 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3267 for the original report.
3269 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3271 * xdisp.c (redisplay_window): Remove inner local variable
3272 because the outer shadowed one has the same meaning.
3273 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3275 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3276 (xg_create_tool_bar): Adjust users.
3278 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3280 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3281 * buffer.c (Fget_buffer_create): Use it to set compact field of
3282 struct buffer_text to avoid accessing an uninitialized value
3283 when compact_buffer is called for the first time.
3284 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3285 (Fset_buffer_modified_p): Use buffer_window_count to check
3286 whether the buffer is displayed in some window.
3287 * xdisp.c (message_dolog): Likewise.
3289 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3291 * w32.c (acl_set_file): If setting the file security descriptor
3292 fails, and the new DACL is identical to the existing one, silently
3293 return success. This fixes problems for users backing up their
3294 own files without having the necessary privileges for setting
3295 security descriptors.
3297 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3299 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3300 after WaitForSingleObject returns normally. This expedites reader
3301 thread shutdown when delete_child triggers it.
3302 (reap_subprocess): More accurate commentary for why we call
3303 delete_child only when cp->fd is negative.
3305 * w32.c (sys_close): Do not call delete_child on a subprocess
3306 whose handle is not yet closed. Instead, set its file descriptor
3307 to a negative value, so that reap_subprocess will call
3308 delete_child on that subprocess when its SIGCHLD arrives.
3309 This avoids closing handles used for communications between sys_select
3310 and reader_thread, which doesn't give sys_select a chance to
3311 notice that the process exited and invoke the SIGCHLD handler for
3314 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3316 * nsfns.m (Fns_do_applescript): Run event loop until script has
3317 been executed (Bug#12969).
3318 (ns_run_ascript): Chech as_script for nil, set to nil after
3321 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3323 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3325 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3327 * w32term.c (w32fullscreen_hook): New function.
3328 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3330 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3332 * fileio.c (Finsert_file_contents): Doc fix.
3334 * w32proc.c (new_child, delete_child, find_child_pid): For a
3335 subprocess, consider its slot being in use as long as its process
3336 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3337 slot when a new process is started immediately after killing
3338 another one, without waiting enough time for the first process to
3339 be reaped and resources allocated for it be orderly freed.
3341 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3343 2012-12-21 Chong Yidong <cyd@gnu.org>
3345 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3347 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3349 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3351 * w32.c (get_name_and_id): Always pass NULL as the first argument
3352 of lookup_account_sid. Avoids crashes with UNC file names that
3353 refer to DFS domains, not to specific machine names. (Bug#12621)
3354 Remove now unused argument FNAME; all callers changed.
3355 (get_file_owner_and_group): Remove now unused argument FNAME; all
3358 2012-12-21 Chong Yidong <cyd@gnu.org>
3360 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3361 error for invalid chars, don't check for a nil return value.
3363 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3365 Avoid calls to CHAR_TO_BYTE if byte position is known.
3366 * editfns.c (make_buffer_string_both): Use move_gap_both.
3367 (Fbuffer_string): Use make_buffer_string_both.
3368 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3370 (buf_bytepos_to_charpos): Likewise.
3371 (charpos_to_bytepos): Remove.
3372 * fileio.c (Finsert_file_contents): Use move_gap_both.
3373 * search.c (Freplace_match): Likewise.
3374 * process.c (process_send_region): Likewise. Use convenient
3375 names for byte positions.
3376 * lisp.h (charpos_to_bytepos): Remove prototype.
3377 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3378 * insdel.c (move_gap): Likewise.
3380 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3382 * xdisp.c (redisplay_internal): Remove now-unused local.
3384 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3386 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3387 (redisplay_internal): Don't bother selecting the frame to get the
3388 proper value of frame-local variables (bug#13225).
3390 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3392 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3393 Rename 4th argument since it may be buffer or string. Adjust comment.
3394 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3396 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3398 * coding.c (Fdetect_coding_region): Do not check start and end with
3399 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3400 (code_convert_region): Likewise.
3402 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3404 * w32.c (acl_get_file, acl_set_file): Run the file name through
3405 map_w32_filename, and resolve any symlinks in the file name, like
3407 (acl_set_file): Call revert_to_self, if any privileges were
3410 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3412 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3413 ($(BLD)/w32.$(O)): Update dependencies.
3415 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3417 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3418 propagate redisplay's scrolling (if any) to the right window.
3419 (redisplay_internal): Use ensure_selected_frame.
3420 (display_mode_lines): Complete last fix.
3421 * window.c (select_window_1): New func, extracted from select_window.
3422 (select_window): Use it.
3423 * window.h (select_window_1): Declare.
3425 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3427 Emulate Posix ACL APIs on MS-Windows.
3428 * w32.c: Include sddl.h and sys/acl.h.
3429 (SDDL_REVISION_1): Define if not already defined.
3430 (g_b_init_get_security_descriptor_dacl)
3431 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3432 (g_b_init_is_valid_security_descriptor)
3433 (g_b_init_set_file_security): New static flags.

3444 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
3445 (acl_free, acl_get_file, acl_set_file): New functions.
3447 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3449 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3451 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3452 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3453 for some of that bug's symptoms can now cause Emacs to abort.
3454 Remove the workaround.
3455 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3456 The bug that caused SIGCHLD to get lost has been fixed, and the
3457 workaround for it can now cause Emacs to abort.
3459 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3461 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3462 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3463 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3465 2012-12-16 Romain Francoise <romain@orebokech.com>
3467 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3468 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3469 and copy ACL entries of file in addition to SELinux context if set.
3470 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3472 * Makefile.in (LIBACL_LIBS): New macro.
3475 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3477 * fileio.c (internal_delete_file): Use bool for boolean.
3479 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3481 Fix bug #13079 on MS-Windows with temp files not being deleted.
3482 * w32.h (_child_process): New members input_file and
3484 (register_child): First argument is now pid_t.
3485 (record_infile, record_pending_deletion): New prototypes.
3487 * w32proc.c (new_child): Initialize input_file and
3488 pending_deletion members of the child.
3489 (delete_child): Delete the child's temporary input file, if any,
3490 that is pending deletion.
3491 (register_child): First argument is now pid_t.
3492 (record_infile, record_pending_deletion): New functions.
3493 (reap_subprocess): Fix a typo in DebPrint string.
3494 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3496 * fileio.c (internal_delete_file): Return an int again: non-zero
3497 if delete-file succeeds, zero otherwise.
3499 * lisp.h (internal_delete_file): Adjust prototype.
3501 * callproc.c (Fcall_process): Don't overwrite infile with result
3503 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3504 asynchronous subprocess, record the name of the input file name,
3506 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3507 delete the file, record it as pending deletion when the subprocess
3510 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3512 * editfns.c [HAVE_PWD_H]: Include grp.h.
3514 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3516 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3518 Fix permissions bugs with setgid directories etc. (Bug#13125)
3519 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3520 to mark it as a placeholder. The old value was often wrong.
3521 The only user of this attribute has been changed to use
3522 file-ownership-preserved-p instead, with its new group arg.
3523 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3525 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3527 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

3530 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3532 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3533 try to get accurate owner and group information from NT file
3534 security APIs. This is to make most callers of 'stat' and
3535 'lstat', which don't need that information, much faster.
3537 * dired.c (Ffile_attributes) [WINDOWSNT]:
3538 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3539 owner and group information from 'lstat'.
3541 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3543 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3544 as that confuses set-auto-coding, so insist on the head-read
3545 returning the full 1024 bytes. Let lseek compute the tail offset;
3546 less work for us. Do not ignore I/O errors when reading the tail.
3548 * xdisp.c: Minor style fixes.
3549 (init_iterator): Hoist assignment out of if-expression.
3550 (markpos_of_region): Callers now test for sign, not for -1.
3552 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3554 Minor redisplay optimization when the region length is zero.
3555 * xdisp.c (markpos_of_region): New function.
3556 (init_iterator): Do not highlight the region of zero length.
3557 (redisplay_window): Check whether the region is of non-zero length.
3558 (try_cursor_movement): Allow if the region length is zero.
3559 (try_window_reusing_current_matrix, try_window_id): Likewise.
3561 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3563 * search.c (search_buffer): Check the inverse translations of each
3564 character in pattern when the buffer being searched is unibyte.
3567 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3569 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3570 files, fixing a regression from 24.2.
3571 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3573 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3575 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3576 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3577 Remove unnecessary S_ISLNK test, as (contra the comments) this
3578 function can't copy symlinks. Improve quality of error message
3579 when attempting to copy files that are neither regular files nor

3586 * window.c (Frecenter):
3587 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3588 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3590 2012-12-12 Daniel Colascione <dancol@dancol.org>
3592 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3593 the dumped Emacs is not a sparse file, greatly improving Cygwin
3594 "make bootstrap" performance.
3596 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3598 * inotify.c (inotify_callback): Generate an Emacs event for every
3599 incoming inotify event.
3601 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3603 * xdisp.c (handle_face_prop): Fix logic of computing
3604 it->start_of_box_run_p.
3605 (append_space_for_newline): If the glyph row is R2L, reset the
3606 iterator's end_of_box_run_p flag before prepending the space glyph.
3607 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3608 iterator's start_of_box_run_p flag before prepending the stretch.
3609 (append_glyph, produce_image_glyph, append_composite_glyph)
3610 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3611 left_box_line_p and right_box_line_p flags of the glyph for R2L
3612 glyph rows. (Bug#13011)
3614 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3616 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
3617 if changed buffer is not shown in a window.
3618 * insdel.c (prepare_to_modify_buffer): Likewise.
3619 * window.c (replace_buffer_in_windows_safely): Do nothing
3620 if buffer is not shown in a window.
3621 (Fforce_window_update): Likewise if string or buffer argument
3624 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3626 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3627 encoded_file_name, which is what it is.
3629 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3631 Consistently use marker_position and marker_byte_position.
3632 * fringe.c (Ffringe_bitmaps_at_pos):
3633 * indent.c (Fvertical_motion):
3634 * insdel.c (prepare_to_modify_buffer):

3639 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
3640 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
3641 Replace direct access to marker fields with calls
3642 to marker_position and/or marker_byte_position.
3644 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
3646 * makefile.w32-in (SIG2STR_H): New macro.
3647 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
3648 ($(BLD)/w32notify.$(O)): Update dependencies.
3650 2012-12-10 Daniel Colascione <dancol@dancol.org>

3653 Windows file notification functionality unless WINDOWSNT.
3655 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3658 * w32fns.c (cache_system_info): Initialize the global hinst
3659 variable here so various initialization calls DTRT.
3661 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3662 (hinst): Remove unneeded extern declaration.
3663 (_start): Remove initialization of above variables; remove
3664 initialization of hinst, as cache_system_info now does that.
3666 * emacs.c (main): Call cache_system_info early in startup; we
3667 previously weren't calling it in Cygwin builds.
3669 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
3670 Teach the autoconf build system how to compile a Windows resource file
3671 and link it to Emacs.

3684 and buffer_local_symbols.
3685 * window.h (buffer_shared): Remove declaration.
3686 (wset_buffer): Convert from inline ...
3687 * window.c (wset_buffer): ... to an ordinary function.
3688 (adjust_window_count): New function.
3689 (make_parent_window): Use it.
3690 * xdisp.c (buffer_shared): Remove.

3702 indication whether any WM_EMACS_FILENOTIFY messages were found in
3705 * w32inevt.c (handle_file_notifications): New function.

3775 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
3777 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
3778 DWORD_PTR, for compatibility with 64-bit builds.
3780 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):

3806 * w32.c (unsetenv): Return 0 if the input string is too long.
3808 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3810 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3811 * alloc.c (xputenv): New function.
3812 * dbusbind.c (Fdbus_init_bus):
3814 * xterm.c (x_term_init):

3822 instead, use xputenv+unsetenv to set and restore TZ.
3823 (environbuf): Remove static var. All uses removed.

3825 no longer needed here.
3826 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3827 Move to inside set_time_zone_rule; they don't need file scope any more.
3828 (set_time_zone_rule): Maintain the TZ=value string separately.
3829 (syms_of_editfns): Don't initialize initial_tz;
3830 init_editfns now does it.
3831 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3832 * lisp.h (xputenv): New decl.
3834 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

3845 informative (Bug#12992).
3847 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3849 Simplify get_lim_data.
3850 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3851 Remove USG and vlimit methods; no longer used these days.
3852 Add #error catchall just in case.
3854 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3855 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3856 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

3875 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3877 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3878 This will cause a production Emacs to dump core instead of
3881 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3883 * frame.c (make_frame): Do not set window's buffer to t.
3884 * window.c (Fsplit_window_internal): Likewise. Previously it was
3885 used to indicate that the window is being set up. Now we use
3886 set_window_buffer for all new windows, so the condition in ...
3887 (Fset_window_buffer): ... is always true and can be removed.
3889 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3891 Convenient macro to check whether the buffer is hidden.
3892 * buffer.h (BUFFER_HIDDEN_P): New macro.
3893 * frame.c (make_frame): Use it. Adjust comment.
3894 * buffer.c (candidate_buffer): New function.
3895 (Fother_buffer, other_buffer_safely): Use it.
3897 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3899 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3900 if the child process is still running. Instead, exit the wait
3901 loop and return zero. (Bug#13086)
3903 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3905 * frame.h (x_char_width, x_char_height): Remove prototypes.

3919 * callproc.c, process.h (record_kill_process):
3920 New function, containing part of the old call_process_kill.
3921 (call_process_kill): Use it.
3922 This does not change call_process_kill's behavior.
3923 * process.c (Fdelete_process): Use record_kill_process to fix a
3924 race condition that could cause Emacs to lose track of a child.
3926 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3928 Avoid code duplication between prev_frame and next_frame.
3929 * frame.c (candidate_frame): New function. Add comment.
3930 (prev_frame, next_frame): Use it. Adjust comment.
3932 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3934 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3935 fails, signal an error instead of continuing with an empty
3937 Encode expanded temp file pattern before passing it to mkstemp or
3940 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3941 Encode the file name before passing it to dostounix_filename, in
3942 case it will downcase it (under w32-downcase-file-names).
3945 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3947 Minor call-process cleanups.
3948 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3949 at the same time as other platforms, to simplify analysis.
3950 No need for fd0_volatile since we have synch_process_fd.
3951 Avoid needless emacs_close; arg is always negative.
3953 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3955 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3958 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3960 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3961 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3962 and mouse_face_hidden members to a bitfields.
3963 * frame.h (struct frame): Remove set-but-not-used space_width member.
3964 (FRAME_SPACE_WIDTH): Remove.
3965 * nsterm.m, w32term.c, xterm.c: Adjust users.
3966 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3967 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3968 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3969 members to a bitfields.
3971 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3973 Don't let call-process be a zombie factory (Bug#12980).
3974 Fixing this bug required some cleanup of the signal-handling code.
3975 As a side effect, this change also fixes a longstanding rare race
3976 condition whereby Emacs could mistakenly kill unrelated processes,
3977 and it fixes a bug where a second C-g does not kill a recalcitrant
3978 synchronous process in GNU/Linux and similar platforms.
3979 The patch should also fix the last vestiges of Bug#9488,
3980 a bug which has mostly been fixed on the trunk by other changes.
3981 * callproc.c, process.h (synch_process_alive, synch_process_death)
3982 (synch_process_termsig, sync_process_retcode):
3983 Remove. All uses removed, to simplify analysis and so that
3984 less consing is done inside critical sections.
3985 * callproc.c (call_process_exited): Remove. All uses replaced
3986 with !synch_process_pid.
3987 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3988 These take the role of what used to be in unwind-protect arg.
3990 (block_child_signal, unblock_child_signal):
3991 New functions, to avoid races that could kill innocent-victim processes.
3992 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3993 (call_process_kill): Record killed processes as deleted, so that
3994 zombies do not clutter up the system. Do this inside a critical
3995 section, to avoid a race that would allow the clutter.
3996 (call_process_cleanup): Fix code so that the second C-g works again
3997 on common platforms such as GNU/Linux.
3998 (Fcall_process): Create the child process in a critical section,
3999 to fix a race condition. If creating an asynchronous process,
4000 record it as deleted so that zombies do not clutter up the system.
4001 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4002 light of these changes. Omit unnecessary call to emacs_close
4003 before failure, as the unwind-protect code does that.
4004 * callproc.c (call_process_cleanup):
4005 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4006 * process.c (record_deleted_pid): New function, containing
4007 code refactored out of Fdelete_process.
4008 (Fdelete_process): Use it.
4009 (process_status_retrieved): Remove. All callers changed to use
4010 child_status_change.
4011 (record_child_status_change): Remove, folding its contents into ...
4012 (handle_child_signal): ... this signal handler. Now, this
4013 function is purely a handler for SIGCHLD, and is not called after
4014 a synchronous waitpid returns; the synchronous code is moved to
4015 wait_for_termination. There is no need to worry about reaping
4016 more than one child now.
4017 * sysdep.c (get_child_status, child_status_changed): New functions.
4018 (wait_for_termination): Now takes int * status and bool
4019 interruptible arguments, too. Do not record child status change;
4020 that's now the caller's responsibility. All callers changed.
4021 Reimplement in terms of get_child_status.
4022 (wait_for_termination_1, interruptible_wait_for_termination):
4023 Remove. All callers changed to use wait_for_termination.
4024 * syswait.h: Include <stdbool.h>, for bool.
4025 (record_child_status_change, interruptible_wait_for_termination):
4027 (record_deleted_pid, child_status_changed): New decls.
4028 (wait_for_termination): Adjust to API changes noted above.
4030 * bytecode.c, lisp.h (Qbytecode): Remove.
4031 No longer needed after 2012-11-20 interactive-p changes.
4033 2012-12-03 Eli Zaretskii <eliz@gnu.org>
4035 * xdisp.c (redisplay_window): If the cursor is visible, but inside
4036 the scroll margin, move point outside the margin. (Bug#13055)
4038 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
4040 * gtkutil.c (my_log_handler): New function.
4041 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4043 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4045 * lisp.h (modify_region): Rename to...
4046 (modify_region_1): ...new prototype.
4047 * textprop.c (modify_region): Now static. Adjust users.
4048 * insdel.c (modify_region): Rename to...
4049 (modify_region_1): ...new function to work with current buffer.
4050 Adjust comment and users. Use true and false for booleans.
4052 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4054 * alloc.c (free_save_value): New function.
4055 (safe_alloca_unwind): Use it.
4056 * lisp.h (free_save_value): New prototype.
4057 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4059 (save_excursion_restore): Adjust to match saved data structure.
4060 Use free_save_value to offload some work from GC. Drop obsolete
4063 2012-12-03 Chong Yidong <cyd@gnu.org>
4065 * fileio.c (Vauto_save_list_file_name): Doc fix.
4067 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4069 * w32fns.c: Remove prototype of atof.
4070 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
4072 (file_dialog_callback): Make it UINT_PTR.
4074 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
4077 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4078 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
4081 2012-12-03 Glenn Morris <rgm@gnu.org>
4083 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
4085 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
4087 Fix xpalloc confusion after memory is exhausted.
4088 * alloc.c (xpalloc): Comment fix.
4089 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4090 and signals an error, do not clear charset_table_size, as
4091 charset_table is still valid.
4092 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4094 Use execve to avoid need to munge environ (Bug#13054).
4095 * callproc.c (Fcall_process):
4096 * process.c (create_process):
4097 Don't save and restore environ; no longer needed.
4098 * callproc.c (child_setup):
4099 Use execve, not execvp, to preserve environ.
4101 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4103 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
4105 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4107 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
4108 display for sliced images (Bug#10500).
4110 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
4112 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
4114 * doc.c (Fdocumentation): Re-add handling of function-documentation,
4115 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4117 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4119 * xdisp.c (window_outdated): Remove eassert since it hits
4120 some suspicious corner cases (see Bug#13007 and Bug#13012).
4121 (mode_line_update_needed): New function.
4122 (redisplay_internal, redisplay_window): Use it.
4123 (ensure_selected_frame): New function.
4124 (redisplay_internal, unwind_redisplay): Use it.
4125 (redisplay_internal): Move comment about buffer_shared...
4126 (buffer_shared_and_changed): ...near to its real use.
4128 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
4130 * callproc.c (Fcall_process): Don't misreport vfork failure.
4132 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4134 * callproc.c (Fcall_process): Fix vfork portability problems.
4135 Do not assume that fd[0], count, filefd, and save_environ survive
4136 vfork. Fix bug whereby wrong errno value could be reported for
4137 pipe failure. Some minor cleanups, too, as follows. Move buf and
4138 bufsize to the context where they're needed. Change new_argv to
4139 be of type char **, as this is more convenient and avoids casts.
4140 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4141 Now local constants, not macros.
4143 2012-11-18 Kenichi Handa <handa@gnu.org>

4189 were always defined.
4191 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4193 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4194 between bpos_covered and bpos_max. This fixes cursor display when
4195 several display strings follow each other.
4197 * .gdbinit (pgx): If the glyph's object is a string, display the
4198 pointer to string data, rather than the value of the string object
4199 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4201 * indent.c (Fvertical_motion): If the starting position is covered
4202 by a display string, return to one position before that, to avoid
4203 overshooting it inside move_it_to. (Bug#12930)
4205 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4207 * frame.h (struct frame): Remove display_preempted member
4208 since all users are dead long ago.
4209 * nsterm.h (struct x_output): Use the only dummy member.
4210 * w32menu.c (pending_menu_activation): Remove since not
4212 (set_frame_menubar): Adjust user.
4213 * w32term.h (struct x_output): Drop outdated #if 0 code.
4214 (struct w32_output): Use bitfields for explicit_parent,
4215 asked_for_visible and menubar_active members.
4216 Drop unused pending_menu_activation member.
4217 * xterm.h (struct x_output): Drop outdated #if 0 code.
4218 Use bitfields for explicit_parent, asked_for_visible,
4219 has_been_visible and net_wm_state_hidden_seen members.
4221 2012-11-23 Eli Zaretskii <eliz@gnu.org>
4223 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4224 of a literal "/". (Bug#12955)
4225 (gl-stamp): Invoke fc.exe directly, not through cmd.
4227 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4229 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4230 * dired.c: Assume HAVE_DIRENT_H.
4231 (NAMLEN): Remove, replacing with ...
4232 (dirent_namelen): New function. All uses changed. Use the GNU macro
4233 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4234 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4235 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4236 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4238 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4239 * ndir.h: Rename to ../nt/inc/dirent.h.
4240 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4241 Do not include <dirent.h>; no longer needed.
4242 * w32.c: Include <dirent.h> rather than "ndir.h".
4244 2012-11-23 Chong Yidong <cyd@gnu.org>
4246 * xftfont.c (xftfont_open): Remove duplicate assignment.
4248 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4250 * alloc.c (Fgarbage_collect): Unblock input after clearing
4251 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4252 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4253 * msdos.c (IT_frame_up_to_date): Use it here...
4254 * w32term.c (w32_frame_up_to_date): ...here...
4255 * xterm.c (XTframe_up_to_date): ...and here...
4256 * nsterm.m (ns_frame_up_to_date): ...but not here.
4257 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4259 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4260 Do not check whether GC is in progress.
4262 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4264 * xdisp.c (window_buffer_changed): New function.
4265 (update_menu_bar, update_tool_bar): Use it to
4266 simplify large 'if' statements.
4267 (redisplay_internal): Generalize commonly used
4268 'tail' and 'frame' local variables.
4270 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4272 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4273 with Windows system header.
4275 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4277 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4278 * alloc.c: Assume unistd.h exists.
4279 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4280 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4281 (getwd) [USG]: Remove; no longer needed.
4282 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4283 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4284 * w32.h (getcwd): Remove decl.
4286 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4288 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4289 Make it set selected_window as well.
4290 (update_tool_bar): Use it.
4292 2012-11-21 Ken Brown <kbrown@cornell.edu>
4294 * emacs.c (main): Set the G_SLICE environment variable for all
4295 Cygwin builds, not just GTK builds. See
4296 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4298 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4300 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4301 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4302 Define for the MSVC compiler.
4304 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4306 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4307 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4308 dostounix_filename. Prevents crashes down the road, because
4309 dostounix_filename assumes it gets a unibyte string.
4310 Reported by Michel de Ruiter <michel@sentient.nl>, see
4311 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
4313 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4315 Conflate Qnil and Qunbound for `symbol-function'.
4316 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
4317 * lread.c (init_obarray): Set `function' fields to Qnil.
4318 * eval.c (Fcommandp): Ignore Qunbound.
4319 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
4320 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
4321 Test NILP rather than Qunbound.
4322 (Ffmakunbound): Set to Qnil.
4323 (Fsymbol_function): Never signal an error.
4324 (Finteractive_form): Ignore Qunbound.
4326 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
4328 * eval.c (interactive_p): Remove no-longer-used decl.
4330 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4332 * xdisp.c (buffer_shared): Adjust comment.
4333 (buffer_shared_and_changed): New function.
4334 (prepare_menu_bars, redisplay_internal): Use it to
4335 decide whether all windows or frames should be updated.
4336 (window_outdated): New function.
4337 (text_outside_line_unchanged_p, redisplay_window): Use it.
4338 (redisplay_internal): Likewise. Fix indentation.
4340 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4342 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4343 (syms_of_eval): Remove corresponding defsubr.
4344 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4346 2012-11-19 Daniel Colascione <dancol@dancol.org>
4348 * w32fns.c (Fx_file_dialog):
4349 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4350 cygwin_convert_file_name*.
4352 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4353 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4355 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4357 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4359 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4361 * w32select.c: Include w32common.h before w32term.h, so that
4362 windows.h gets included before w32term.h uses some of its
4363 features, see below.
4365 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4367 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4369 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4371 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4373 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4374 (ns_select): Return at once if events are held (Bug#12834).
4376 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4378 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4379 Needed following 2012-10-20 change. (Bug#12902)
4381 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4383 * w32proc.c (waitpid): Remove unused label get_result.
4385 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4387 * makefile.w32-in (SYSWAIT_H): New macro.
4388 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4389 ($(BLD)/sysdep.$(O)): Update dependencies.
4391 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4393 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4394 * callproc.c (relocate_fd): Assume F_DUPFD.
4395 * emacs.c, term.c (O_RDWR): Remove.
4396 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4397 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4398 * nsterm.m: Assume <fcntl.h> exists.
4399 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4400 (create_pty, Fmake_network_process, server_accept_connection)
4401 (wait_reading_process_output, init_process_emacs):
4403 (wait_reading_process_output): Put in a special case for WINDOWSNT
4404 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4405 It's not clear this is needed, but it's a more-conservative change.
4406 (create_process): Assume FD_CLOEXEC.
4407 (create_process, create_pty): Assume O_NOCTTY.
4408 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4409 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4410 Omit if not DOS_NT, since F_GETFL is not defined there.
4411 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4412 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4414 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4415 lack it, since gnulib guarantees this.
4416 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4418 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4420 * w32.c (faccessat): Pretend that directories have the execute bit
4421 set. Emacs expects that, e.g., in files.el:cd-absolute.
4423 * w32proc.c (create_child): Don't clip the PID of the child
4424 process to fit into an Emacs integer, as this is no longer a
4426 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4427 reaping only the process specified by PID argument, if that is
4428 positive. Use PID instead of dead_child to know which process to
4429 reap. Wait for the child to die only if WNOHANG is not in
4431 (sys_select): Don't set dead_child.
4433 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4434 as it is no longer needed.
4436 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4438 (record_child_status_change): Remove the setting of
4439 record_at_most_one_child for the !WNOHANG case.
4441 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4443 Fix problems in ns port found by static checking.
4444 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4445 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4446 not to process group.
4447 (ns_select): Use emacs_write, not write, as that's more robust
4448 in the presence of signals.
4449 (fd_handler:): Check for read errors.
4451 2012-11-16 Glenn Morris <rgm@gnu.org>
4453 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4455 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4457 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4459 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4461 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4462 use the same value of thread handle.
4463 (start_timer_thread): If the timer thread exited (due to error),
4464 clean up by closing the two handles it used. Duplicate the caller
4465 thread's handle here, so it gets duplicated only once, when
4466 launching the timer thread. Set priority of the timer thread, not
4468 (getitimer): Don't duplicate the caller thread's handle here.
4471 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4473 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4476 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4478 Remove no-longer-used pty_max_bytes variable.
4479 * process.c (pty_max_bytes): Remove; unused.
4480 (send_process): Do not set it.
4482 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4484 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4485 Update dependencies.
4487 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4489 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4490 This follows up on the 2012-09-29 patch that removed indirection
4491 for the 'function' field. Reported by Sergey Vinokurov in
4492 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4494 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4496 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4497 different name, as the MS runtime does not have such a function,
4498 and probably never will.) All callers changed. Ignore DIRFD
4499 value if PATH is an absolute file name, to match Posix spec
4500 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4503 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4505 * xdisp.c (echo_area_display, redisplay_internal):
4506 Omit redundant check whether frame_garbaged is set.
4508 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4510 Use faccessat, not access, when checking file permissions (Bug#12632).
4511 This fixes a bug that has been present in Emacs since its creation.
4512 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4513 which must set some sort of record. (Torek's bug report was against
4514 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4515 same common flaw.) See Torek's Usenet posting
4516 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4517 Posted: Fri Apr 8 14:18:56 1983.
4518 * Makefile.in (LIB_EACCESS): New macro.
4520 * callproc.c (init_callproc):
4521 * charset.c (init_charset):
4522 * fileio.c (check_existing, check_executable, check_writable)
4524 * lread.c (openp, load_path_check):
4525 * process.c (allocate_pty):
4527 Use effective UID when checking permissions, not real UID.
4528 * callproc.c (init_callproc):
4529 * charset.c (init_charset):
4530 * lread.c (load_path_check, init_lread):
4531 Test whether directories are accessible, not merely whether they exist.
4532 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4533 * fileio.c (check_existing, check_executable, check_writable)
4535 Use symbolic names instead of integers for the flags, as they're
4537 (check_writable): New arg AMODE. All uses changed.
4538 Set errno on failure.
4539 (Ffile_readable_p): Use faccessat, not stat + open + close.
4540 (Ffile_writable_p): No need to call check_existing + check_writable.
4541 Just call check_writable and then look at errno. This saves a syscall.
4542 dir should never be nil; replace an unnecessary runtime check
4543 with an eassert. When checking the parent directory of a nonexistent
4544 file, check that the directory is searchable as well as writable, as
4545 we can't create files in unsearchable directories.
4546 (file_directory_p): New function, which uses 'stat' on most platforms
4547 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4548 (Ffile_directory_p, Fset_file_times): Use it.
4549 (file_accessible_directory_p): New function, which uses a single
4550 syscall for efficiency.
4551 (Ffile_accessible_directory_p): Use it.
4552 * xrdb.c (file_p): Use file_directory_p.
4553 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4554 * lread.c (openp): When opening a file, use fstat rather than
4555 stat, as that avoids a permissions race. When not opening a file,
4556 use file_directory_p rather than stat.
4557 (dir_warning): First arg is now a usage string, not a format.
4558 Use errno. All uses changed.
4559 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4560 that merely introduced a race.
4561 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4562 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4563 and similarly for the other O_* flags.
4564 * w32.c (sys_faccessat): Rename from sys_access and switch to
4565 faccessat's API. All uses changed.
4566 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4567 (magic_db): Rename from magic_file_p.
4568 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4569 char *, so that we don't have to test for file existence
4570 separately from opening the file for reading. This removes a race
4571 fixes a permission-checking problem, and simplifies the code.
4573 (file_p): Remove; no longer needed.
4575 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4577 Omit glyphs initialization at startup.
4578 * dispnew.c (glyphs_initialized_initially_p): Remove.
4579 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4580 (Fredraw_frame): Move actual code from here...
4581 (redraw_frame): ...to here. Add eassert. Adjust comment.
4582 (Fredraw_display): Use redraw_frame.
4583 * xdisp.c (clear_garbaged_frames): Likewise.
4585 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4587 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4588 passed to pint2str and pint2hrstr to be at most the size of the
4589 frame's decode_mode_spec_buffer. This avoids crashes with very
4590 large values of FIELD_WIDTH argument to decode_mode_spec.
4593 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4595 Fix a race with verify-visited-file-modtime (Bug#12863).
4596 Since at least 1991 Emacs has ignored an mtime difference of no
4597 more than one second, but my guess is that this was to work around
4598 file system bugs that were fixed long ago. Since the race is
4599 causing problems now, let's remove that code.
4600 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4601 whose time stamp is off by no more than a second. Insist that the
4602 file time stamps match exactly.
4604 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4606 * frame.h (struct frame): Convert external_tool_bar member to
4607 1-bit unsigned bitfield.
4608 * termhooks.h (struct terminal): Remove mouse_moved member since
4609 all users are long dead. Adjust comment on mouse_position_hook.
4611 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4613 Simplify by using FOR_EACH_FRAME here and there.
4614 * frame.c (next_frame, prev_frame, other_visible_frames)
4615 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4616 * w32term.c (x_window_to_scroll_bar): Likewise.
4617 * window.c (window_list): Likewise.
4618 * xdisp.c (x_consider_frame_title): Likewise.
4619 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4620 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4621 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4622 * xmenu.c (menubar_id_to_frame): Likewise.
4623 * xselect.c (frame_for_x_selection): Likewise.
4624 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4625 (x_window_to_menu_bar): Likewise.
4626 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4628 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4630 * data.c (Qdefalias_fset_function): Now static.
4632 Another tweak to vectorlike_header change.
4633 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4634 Remove, and replace all uses with ...
4635 (next_in_free_list, set_next_in_free_list):
4636 New functions, which respect C's aliasing rules better.
4638 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4640 * window.c (list4i): Rename from 'quad'. All uses changed.
4641 Needed because <sys/types.h> defines 'quad' on Solaris 10.

4655 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4657 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4658 amount when the scroll margins are too large. When scrolling
4659 backwards in the buffer, give up if cannot reach point or the
4660 scroll margin within a reasonable number of screen lines.
4661 Fixes point position in window under scroll-up/down-aggressively when
4662 point is positioned many lines beyond the window top/bottom.
4665 * ralloc.c (relinquish): If real_morecore fails to return memory
4666 to the system, don't crash; instead, leave the last heap
4667 unchanged and return. (Bug#12774)

4688 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4690 Fix recently introduced crash on MS-Windows (Bug#12839).
4691 * w32term.h (struct scroll_bar): Use convenient header.
4692 (SCROLL_BAR_VEC_SIZE): Remove.
4693 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4695 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4697 Tweak last vectorlike_header change.
4698 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4699 vectorlike object on the free list. This is introduced to avoid
4700 some (but not all) pointer casting and aliasing problems, see
4701 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4702 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4706 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4708 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4709 been removed, so remove them here also.
4711 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4713 * doc.c (Fdocumentation): Handle new property
4714 dynamic-docstring-function to replace the old ad-advice-info.
4716 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4718 * fns.c (Qeql, hashtest_eq): Now static.
4720 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4722 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4723 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4724 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

4729 Use same hash function for hashfn_profiler as for hash_string etc.
4730 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4731 * lisp.h (sxhash_combine): New inline function, with the contents
4732 of the old SXHASH_COMBINE.
4733 * profiler.c (hashfn_profiler): Use it, instead of having a
4734 special hash function containing a comparison that always yields 1.
4736 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4738 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4739 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4740 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4743 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4745 * image.c (xpm_make_color_table_h): Fix compiler error because
4746 make_hash_table changed.
4748 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4750 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4752 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4754 Use ad-hoc comparison function for the profiler's hash-tables.
4755 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4756 (make_log): Use them.
4757 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4758 call Fequal any more.

4767 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4768 (hash_lookup, hash_remove_from_table): Move assertion checking of
4769 hashfn result here. Check hash-equality before calling cmpfn.

4781 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4782 value of w32-scroll-lock-modifier is neither nil nor one of the
4783 known key modifiers. (Bug#12806)
4785 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4787 Shrink struct vectorlike_header to the only size field.
4788 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4790 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4791 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4792 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4793 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4794 information from the vector header. Adjust comment.

4809 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4810 (large_vectors): Change type to struct large_vector.
4811 (allocate_vector_from_block): Simplify.
4812 (PSEUDOVECTOR_NBYTES): Replace with...
4813 (vector_nbytes): ...new function. Adjust users.
4814 (sweep_vectors): Adjust processing of large vectors.
4815 (allocate_vectorlike): Likewise.
4816 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4817 Add easserts. Adjust XSETPVECTYPESIZE usage.
4818 (allocate_buffer): Use BUFFER_PVEC_INIT.
4819 (live_vector_p): Adjust to match large vector.
4820 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4821 * buffer.h (struct buffer): Add next member.
4822 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4824 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4825 * fns.c (internal_equal): Adjust to match enum pvec_type change.

4830 (xvecsize): New command.
4832 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4834 * keyboard.c (event_to_kboard): Do not dereference
4835 frame_or_window field of SELECTION_REQUEST_EVENT
4836 and SELECTION_CLEAR_EVENT events (Bug#12814).
4837 * xterm.h (struct selection_input_event): Adjust comment.
4839 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4841 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4842 such as Scroll Lock, if the respective keys are treated as
4843 function keys, not as modifiers. This avoids destroying non-ASCII
4844 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4846 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4848 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4850 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4852 Restore some duplicate definitions (Bug#12814).
4853 This undoes part of the 2012-11-03 changes. Some people build
4854 with plain -g rather than with -g3, and they need the duplicate
4855 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4856 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4857 Define as macros, as well as as enums or as constants.
4859 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4861 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4862 to keypad keys (Bug#12816).
4864 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4866 Minor adjustments of recently-changed frame functions.
4867 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4868 known to be a frame (we're in the FRAMEP branch).
4869 * lisp.h (Qframep): Remove decl. frame.h declares this.
4870 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4871 since they're meant for Lisp fixnum values.
4873 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4875 * window.c (Fwindow_combination_limit): Revert to the only
4876 required argument and adjust docstring as suggested in
4877 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4878 by Martin Rudalics <rudalics@gmx.at>.
4880 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4882 Widely used frame validity and checking functions.
4883 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4884 * frame.c (decode_live_frame, decode_any_frame): New functions.
4885 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4886 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4887 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4888 (Fframe_pointer_visible_p): Use decode_any_frame.

4890 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4891 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4892 (Fframe_focus): Likewise. Allow zero number of arguments.
4894 (frame_buffer_list, frame_buffer_predicate): Remove.
4895 * lisp.h (frame_buffer_predicate): Remove prototype.
4896 * buffer.c (Fother_buffer): Use decode_any_frame.
4897 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4898 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4899 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4900 (Fclose_font, Ffont_info): Use decode_live_frame.
4901 * fontset.c (check_fontset_name): Likewise.
4902 * terminal.c (Fframe_terminal): Likewise.
4903 * w32fns.c (check_x_frame): Likewise.
4904 * window.c (Fminibuffer_window, Fwindow_at)
4905 (Fcurrent_window_configuration): Likewise.
4906 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4907 Likewise. Allow zero number of arguments. Adjust docstring.
4908 * dispnew.c (Fredraw_frame): Likewise.
4909 * xfaces.c (frame_or_selected_frame): Remove.
4910 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4911 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4912 (Fframe_face_alist): Use decode_live_frame.
4913 * xfns.c (check_x_frame): Likewise.
4915 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4917 * window.c (quad): New function.
4918 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4919 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4920 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4921 (Fwindow_line_height): Use it.
4922 (Fwindow_fringes): Use list3.
4923 (Fwindow_scroll_bars): Use list4.
4924 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4925 (Fwindow_combination_limit): Allow zero number of arguments.
4927 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4929 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4931 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4932 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4933 file descriptor 2 for standard error. (Bug#12805)
4935 2012-11-05 Chong Yidong <cyd@gnu.org>
4937 * process.c (wait_reading_process_output): Revert previous change.
4939 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4941 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4942 This removes code that has been obsolete since around 1990.
4943 * callproc.c (Fcall_process):
4945 * process.c (create_process):
4946 * term.c (dissociate_if_controlling_tty):
4947 Assume setsid exists.
4948 * callproc.c (child_setup): Assume setpgid exists and behaves as
4949 per POSIX.1-1988 or later.
4950 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4951 * emacs.c (shut_down_emacs):
4952 * sysdep.c (sys_suspend, init_foreground_group):
4953 Assume getpgrp behaves as per POSIX.1-1998 or later.
4954 * msdos.c (setpgrp): Remove.
4955 (tcgetpgrp, setpgid, setsid): New functions.
4956 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4957 * term.c (no_controlling_tty): Remove; unused.
4958 * w32proc.c (setpgrp): Remove.
4959 (setsid, tcgetpgrp): New functions.
4961 Simplify by assuming __fpending.
4962 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4963 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4964 Do not assume that __fpending's result fits in int.
4966 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4968 Remove EMACS_OUTQSIZE+sleep hack.
4969 * dispnew.c (update_frame_1): Remove hack for terminals slower
4970 than 2400 bps, which throttled Emacs by having it sleep.
4971 This code hasn't worked since at least 2007, when the multi-tty stuff
4972 was added, and anyway those old terminals are long dead.
4973 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4974 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4976 Fix data-loss with --version (Bug#9574).
4977 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4978 as we can't assume that emacs_strerror is initialized, and strerror
4979 is good enough here.
4980 (main): Invoke atexit earlier, to catch earlier instances of
4981 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4983 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4985 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4986 (keyDown): Remap keypad keys to X11 virtual key codes.
4988 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4990 Fix data-loss with --batch (Bug#9574).
4991 * emacs.c: Include <close-stream.h>.
4992 (close_output_streams): New function.
4993 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4994 and handles errors appropriately.
4995 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4998 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4999 The symptom is a diagnostic "GLib-WARNING **: In call to
5000 g_spawn_sync(), exit status of a child process was requested but
5001 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5002 waitpid(), so exit status can't be returned." The diagnostic
5003 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5004 The real bug is a race condition between Emacs and glib: Emacs
5005 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5006 so that glib can't find it. Work around the bug by invoking
5007 waitpid only on subprocesses that Emacs itself creates.
5008 * process.c (create_process, record_child_status_change):
5009 Don't use special value -1 in pid field, as the caller now must
5010 know the pid rather than having the callee infer it.
5011 The inference was sometimes incorrect anyway, due to another race.
5012 (create_process): Set new 'alive' member if child is created.
5013 (process_status_retrieved): New function.
5014 (record_child_status_change): Use it.
5015 Accept negative 1st argument, which means to wait for the
5016 processes that Emacs already knows about. Move special-case code
5017 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5018 processes that have already been waited for, by testing and
5019 clearing new 'alive' member.
5020 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5021 now does this internally.
5022 (handle_child_signal): Let record_child_status_change do all
5023 the work, since we do not want to reap all exited child processes,
5024 only the child processes that Emacs itself created.
5025 * process.h (Lisp_Process): New boolean member 'alive'.
5027 Omit duplicate definitions no longer needed with gcc -g3.
5028 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5029 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5030 Define only as macros. There's no longer any need to also define
5031 these symbols as enums or as constants, since we now assume
5032 gcc -g3 when debugging.
5034 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5036 * lisp.mk: Adjust comments to the fact that term/internal is now
5037 loaded from loadup.el.
5039 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5040 (msdos_fatal_signal): New function.
5041 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5044 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5045 for GCC versions before 4.
5046 (emacs_raise): Define to call msdos_fatal_signal.
5048 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5049 iterator when starting in the middle of a display or overlay
5052 2012-11-03 Chong Yidong <cyd@gnu.org>
5054 * process.c (wait_reading_process_output): Clean up the last
5057 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5059 * process.c (wait_reading_process_output): Avoid a race condition
5060 with SIGIO delivery (Bug#11536).
5062 2012-11-03 Chong Yidong <cyd@gnu.org>
5064 * buffer.c (cursor_type): Untabify docstring.
5066 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5068 * frame.h (struct frame): Drop can_have_scroll_bars member
5069 which is meaningless for a long time. Adjust comments.
5070 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.

5114 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5116 Remove pad from struct input_event.
5117 * termhooks.h (struct input_event): Remove padding field.
5119 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5120 member is never cons for a long time. Adjust comment.
5121 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5122 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5123 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5124 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5126 2012-11-01 Eli Zaretskii <eliz@gnu.org>

5130 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5132 Fix crash when using Emacs as commit editor for git (Bug#12697).
5133 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5134 and it is configured in conf_post.h.
5135 (Fcall_process): Don't invoke both setsid and setpgid; the former
5136 is enough, if it exists.
5137 * callproc.c (Fcall_process, child_setup):
5138 * process.c (create_process): Use setpgid.
5139 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5141 * dispnew.c (init_display): Initialize the foreground group
5142 if we are running a tty display.

5155 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5157 * minibuf.c (read_minibuf): Restore current buffer since
5158 choose_minibuf_frame calling Fset_frame_selected_window may
5159 change it (Bug#12766).

5168 displaying the current buffer, signal an error.
5170 2012-10-29 Daniel Colascione <dancol@dancol.org>
5172 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5173 In preparation for fixing bug#12739, move these functions from
5176 * coding.h, coding.c: ... to here, and compile them only when
5177 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5178 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5180 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5182 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

5197 remove last_appdefined_event (Bug#12698).
5199 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5201 * frame.c (x_set_font): Catch internal error.
5203 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5205 Avoid overflow in w32 implementation of interval timers.
5206 When possible, for ITIMER_PROF count only times the main thread
5208 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5209 'volatile ULONGLONG' types. All the other data which was
5210 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5211 (GetThreadTimes_Proc): New typedef.
5212 (w32_get_timer_time): New function, returns a suitable time value
5214 (timer_loop): Enter critical section when accessing ULONGLONG
5215 values of the itimer_data struct, as these accesses are no longer
5216 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5217 Remove unused variable.
5218 (init_timers): Initialize s_pfn_Get_Thread_Times.
5219 (start_timer_thread): Don't assign itimer->caller_thread here.

5226 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5227 mouse movement events if the menu bar is active. This avoids
5228 producing a busy "hour-glass" cursor by Windows if the mouse
5229 pointer is positioned over a tooltip shown for some menu item.
5231 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5233 Don't assume process IDs fit in int.
5234 * emacs.c (shut_down_emacs) [!DOS_NT]:
5235 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5236 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5237 Use pid_t, not int, to store process IDs, as 'int'
5238 is not wide enough on a few platforms (e.g., AIX and IRIX).
5240 2012-10-23 Kenichi Handa <handa@gnu.org>
5242 The following change is to make face-font-rescale-alist work
5243 correctly for non-ASCII fonts.

5263 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5265 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

5268 * frame.c (Fmouse_position, Fmouse_pixel_position):
5269 * xdisp.c (produce_stretch_glyph):
5270 Declare local vars only when they're needed.
5271 This is clearer and avoids a warning on OpenBSD about unused vars.

5273 This is safer, and avoids OpenBSD warnings about unused vars.
5274 * keyboard.c (record_menu_key): Remove unnecessary decl.
5275 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5276 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5277 as our definition clashes with OpenBSD's.
5278 * xfaces.c (load_face_colors, check_lface_attrs)
5279 (get_lface_attributes_no_remap, get_lface_attributes)
5280 (lface_fully_specified_p, x_supports_face_attributes_p)
5281 (tty_supports_face_attributes_p, face_fontset, realize_face)
5282 (realize_x_face, realize_tty_face):
5283 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5284 merely Lisp_Object *. This is more informative and avoids
5285 a warning on OpenBSD about accessing beyond an object's size.
5287 2012-10-20 Chong Yidong <cyd@gnu.org>
5289 * lread.c (Fload): Doc fix (Bug#12592).

5315 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5316 (staticpro): If we run out of staticpro slots, die with an
5317 informative error instead of just calling emacs_abort.
5319 2012-10-18 Martin Rudalics <rudalics@gmx.at>

5573 (detect_input_pending_run_timers):
5574 * process.c (wait_reading_process_output):
5575 Use unsigned for counter where wraparound-on-overflow is desired,
5576 since unsigned is guaranteed to have that behavior and signed is not.
5577 (read_char): Use ptrdiff_t for string length.
5578 (get_input_pending): Remove first argument, since it was always
5579 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5580 and behave as if it had that value. Return new value of
5581 input_pending. All callers changed.
5582 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5583 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5585 * keymap.c (push_key_description): Omit last arg, which was always 1.
5586 All callers changed.

5605 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5606 Don't include termopts.h.
5608 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>

5616 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5618 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5620 (nsfont_open): Remove setting of Vfonts_in_cache.
5621 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5623 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5625 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5626 match what GetLastError returns. Explain why the function is
5629 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5630 'is_tooltip_frame', to avoid confusion with its global namesake.
5632 2012-10-08 Daniel Colascione <dancol@dancol.org>
5634 * xdisp.c (start_hourglass): Call w32_note_current_window when
5635 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5636 build that caused Emacs to display the hourglass cursor forever.
5638 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5639 which is broken under remote desktop, calculate the number of
5640 colors available for a display based on the display's number of
5641 planes and number of bits per pixel per plane. (bug#10397).
5643 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5645 * nsfont.m (Vfonts_in_cache): New variable.
5646 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5647 are used. Add cached fonts to Vfonts_in_cache.
5648 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5650 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5652 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5654 (FONT_H): Define after FRAME_H.
5655 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5656 Update dependencies.
5658 * w32term.c: Remove leftover declaration of keyboard_codepage.
5660 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5662 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5663 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5664 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.

5674 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5676 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5678 2012-10-08 Daniel Colascione <dancol@dancol.org>
5680 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5681 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5682 accidental message numbering hole. Change other messages to
5685 * w32select.h (HAVE_W32SELECT): Remove.
5687 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5688 w32common.h instead of w32heap.h.

5698 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5699 (w32_minor_version, w32_build_number, w32_subtype):
5700 Remove duplicate definitions.
5702 * w32fns.c: Include w32common.h; include w32heap.h only in
5705 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5706 Use `report_file_error' instead of `error' in order to better
5707 inform users of what went wrong. Increase NTGUI_UNICODE file
5708 dialog box file name length to 32k, the maximum allowed by the NT
5711 * w32common.h: New file.
5712 (ROUND_UP, ROUND_DOWN, get_page_size)

5716 (OS_NT, os_subtype, cache_system_info): Move here.
5718 * unexw32.c, unexcw.c: Include w32common.h.
5720 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5721 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5722 to call syms_of_w32select.
5724 * cygw32.h: Remove obsolete EXFUN declarations.
5726 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5728 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5729 of w32inevt.o from SOME_MACHINE_OBJECTS.
5731 2012-10-08 Daniel Colascione <dancol@dancol.org>
5733 * image.c: Permanent fix for JPEG compilation issue --- limit
5734 jpeglib `boolean' redefinition to Cygwin builds.
5736 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5738 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5740 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5743 2012-10-08 Daniel Colascione <dancol@dancol.org>
5745 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5746 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

5750 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5751 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5752 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5753 now a supported configuration.
5755 * Makefile.in: consolidate image variables into LIBIMAGE; add
5756 W32_OBJ and W32_LIBS. Compile new files.
5759 (_DebPrint) declare tracing facility for W32 debugging. We need
5760 to unify tracing later.
5762 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5763 unconditional use of W32 Unicode functions. Cygwin runs only on
5764 100% Unicode operating systems.
5766 * cygw32.c: New file. Define Cygwin-specific facilities.
5767 (Fcygwin_convert_path_to_windows)
5768 (Fcygwin_convert_path_from_windows): New user functions for
5769 accessing Cygwin path-munging routines.
5771 * cygw32.h: New file.
5772 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5773 UTF-16LE strings temporarily inside non-Lisp-visible string
5776 (w32_strerror): Just what it says on the tin.
5778 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5779 also run for Cygwin; both systems have the same problem with using
5780 GUI facilities in a forked child. Also call syms_of_cygw32,
5781 syms_of_w32select in correct places.
5783 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5784 needs fork-then-exec for daemon launching.
5786 * font.h: Include frame.h.
5788 * image.c: Use the image library cache machinery only when we're
5789 compiling for native WINDOWSNT; Cygwin can use shared libraries
5790 like any other Unixlike system.
5792 * keyboard.c: Clarify a comment regarding the input loop.
5794 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5795 functions directly instead of trying to detect at runtime that our
5796 host operating system supports them. We make this change for two
5797 reasons: Cygwin lacks support for the multibyte character
5798 conversion functions used by the legacy menu code, and Cygwin
5799 never needs to rely on non-Unicode APIs.
5801 * unexw32.c (hinst): Declare extern.
5803 * w32.c: Change header order;
5804 (w32_strerror): Move to w32fns.c because we need it for
5805 non-WINDOWSNT builds.
5807 * w32.h: Add #error macro to make sure we don't include w32.h for
5808 Cygwin builds. Remove w32select declarations.
5810 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5811 w32fns.c. w32console.c is WINDOWSNT-only.
5813 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5814 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5816 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5817 (w32_major_version, w32_minor_version, w32_build_number)
5818 (os_subtype, sound_type): Define here
5819 (w32_defined_color): Make color parameter const for consistency
5820 with other _defined_color functions.
5821 (w32_createwindow): Unconditionally call w32_init_class instead of
5822 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5823 through the code is complex and unnecessary because class
5824 registration is practically free.
5825 (w32_name_of_message): New EMACSDEBUG-only function.
5826 (Fset_message_beep): Move here
5827 (Fx_open_connection): Require that the display name for Windows be
5828 "w32" for consistency, emacsclient disambiguation, and maybe, one
5829 day, multi-window-system support.
5830 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5831 Cygwin files for W32 GUI facilities, since these clearly don't
5832 expect Cygwin names.
5833 (_DebPrint): Define.
5834 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5835 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5836 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5837 (w32_last_error): Remove.
5839 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5841 * w32heap.c (syspage_mask): Declare here.
5842 (cache_system_info): Remove.
5844 * w32inevt.c (faked_key): Define globally, not statically.
5845 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5846 (w32_console_toggle_lock_key): Move to w32fns.c.
5848 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5850 * w32proc.c (_DebPrint): Move to w32fns.c.
5851 * w32select.c: Include string.h, stdio.h for Cygwin.
5852 * w32select.h: New File.
5854 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5856 (w32_message_fd): New variable. Under Cygwin, holds the file
5857 descriptor the system used to tell us about pending thread
5860 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5861 that prevented compilation under non-WINDOWSNT systems.
5863 (w32_initialize): Open /dev/windows and assign it to
5864 w32_message_fd. Provide w32 feature.
5866 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5867 (WM_EMACS_INPUT_READY): add.
5868 (prepend_msg, w32_message_fd): Declare globally.
5871 (keyboard_handle): Use only when WINDOWSNT.
5872 (notify_msg_ready): New function. Posts a message to the main
5873 thread's message queue under CYGWIN, which wakes up the main
5874 thread from select(2) by making the /dev/windows file descriptor
5875 ready. Under WINDOWSNT, it sets an event the same way the old
5878 (post, prepend_msg): Actually call notify_msg_ready instead of
5879 setting the input event directly.
5881 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5883 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5884 but it still has blocs in it, don't return it to the system,
5885 instead of aborting. (Bug#12402)
5887 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5889 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5891 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5892 MAC_OS_X_VERSION_10_6.
5893 (syms_of_nsterm): Remove comment about Panther and above for
5895 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5896 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5897 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5899 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5900 MAC_OS_X_VERSION_10_4.
5902 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5903 MAC_OS_X_VERSION_10_2.
5905 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5907 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5908 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5910 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5911 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5912 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5913 Remove ns_in_resize check.
5914 (ns_clear_frame_area): Remove resize handle code.
5916 * nsfns.m (ns_in_resize): Remove.
5917 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5918 Remove ns_in_resize check.
5920 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5922 Improve sys_siglist detection.
5923 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5924 defined as a macro, as is done in Solaris.
5925 (sys_siglist_entries): New macro.
5926 (save_strsignal): Use it.
5927 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5928 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5930 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5932 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5933 fullscreen/Fullscreen.
5935 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5936 tobar_height is new.
5938 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5939 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5940 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5941 (windowDidResize:): Check for correct window if old style fullscreen.
5942 Capitalize word in comment. Remove incorrect comment.
5943 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5944 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5945 error in drawing background.
5946 (toggleFullScreen:): Remove comment. Rearrange calls.
5947 Set toolbar values to zero, save old height in tobar_height.
5948 Restore tool bar height when leaving fullscreen.
5949 (canBecomeMainWindow): New function.
5951 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5953 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5955 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5957 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5959 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5960 that time stamps of directories could also be changed.
5961 Don't request the too broad GENERIC_WRITE, only the more restrictive
5962 FILE_WRITE_ATTRIBUTES access rights.
5964 * fileio.c (Fset_file_times): Special-case ignoring errors for
5965 directories only on MSDOS, not on MS-Windows.
5967 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5969 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5971 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5973 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5974 see whether CreateFile failed.
5976 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5978 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5979 to avoid similar races.
5980 * keyboard.c (pending_signals): Now bool, not int.
5982 Port timers to OpenBSD, plus check for timer failures.
5983 OpenBSD problem reported by Han Boetes.
5984 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5986 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5987 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5988 like OpenBSD, which has timer_settime but does not declare it.
5989 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5990 whether to use itimerspec-related primitives. All uses of
5991 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5993 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5995 * profiler.c (handle_profiler_signal): Fix a malloc race
5996 that caused Emacs to hang on Fedora 17 when profiling Lisp.

6000 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
6002 2012-10-02 Eli Zaretskii <eliz@gnu.org>
6004 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6005 consistent with the change in return value of 'safe_strsignal'.
6007 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6009 Prefer plain 'static' to 'static inline' (Bug#12541).
6010 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
6011 (bidi_set_sor_type, bidi_push_embedding_level)
6012 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
6013 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
6014 (bidi_cache_search, bidi_cache_ensure_space)
6015 (bidi_cache_iterator_state, bidi_cache_find)
6016 (bidi_peek_at_next_level, bidi_set_paragraph_end)
6017 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6018 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
6019 Now 'static', not 'static inline'.
6021 Count overruns when profiling; change units to ns.
6022 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6023 Give extra weight to samples after overruns, to attempt to count
6024 the time more accurately.
6025 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6026 the underlying primitives nominally do ns.
6027 (Fprofiler_cpu_start): Document the change. Mention that
6028 the sampling intervals are only approximate.
6030 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6032 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

6035 case for the special 0 coding-system.
6037 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6038 (Fmake_overlay): Remove redundant tests.
6039 (fix_start_end_in_overlays): Remove redundant recentering.

6048 Fix a malloc race condition involving strsignal.
6049 A signal can arrive in the middle of a malloc, and Emacs's signal
6050 handler can invoke strsignal, which can invoke malloc, which is
6051 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6052 Fix it by altering the signal handler so that it does not invoke
6054 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6055 * process.c (status_message): Use const pointer, in case strsignal
6056 is #defined to safe_strsignal.
6057 * sysdep.c (sys_siglist, init_signals): Always define and
6058 initialize a substitute sys_siglist if the system does not define
6059 one, even if HAVE_STRSIGNAL.
6060 (safe_strsignal): Rename from strsignal. Always define,
6061 using sys_siglist. Return a const pointer.
6062 * syssignal.h (safe_strsignal): New decl.
6063 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6065 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6067 * w32proc.c (timer_loop): Fix code that waits for timer
6068 expiration, to avoid high CPU usage.
6070 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6072 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6073 (sweep_weak_table): Remove redundant prototypes.
6075 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6077 * emacs.c: Move the inclusion of TERM_HEADER after including
6078 windows.h on WINDOWSNT. This avoids compilation problems with
6081 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6083 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6084 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6085 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6086 as the previous version used 'void *'.
6088 * ralloc.c (ROUNDUP): Fix last change.
6089 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6092 * w32proc.c <disable_itimers>: New static flag.
6093 (init_timers): Initialize it to zero, after creating the critical
6094 sections used by the timer threads.
6095 (term_timers): Set to 1 before deleting the critical sections.
6096 (getitimer, setitimer): If disable_itimers is non-zero, return an
6097 error indication without doing anything. Reported by Fabrice
6098 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6099 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6101 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6104 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6105 term_ntproc after all the other bookkeeping, to get timers working
6106 as long as possible.
6108 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6110 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6111 Suggested by Juri Linkov in
6112 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6114 Prefer plain 'static' to 'static inline' (Bug#12541).
6115 With static functions, modern compilers inline pretty well by
6116 themselves; advice from programmers often hurts as much as it helps.
6117 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6118 this change shrinks the text size of the Emacs executable by 1.1%
6119 without affecting CPU significantly in my benchmark.

6199 (bidi_copy_it): Do the whole copy with a single memcpy.
6200 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6202 Revert the FOLLOW-SYMLINKS change for file-attributes.
6203 Doing it right would require several changes to Tramp, and there's
6204 not enough time to get that tested before the freeze today.
6205 * dired.c (directory_files_internal, Ffile_attributes):
6208 * frame.c (x_report_frame_params): Port better to wider ints.
6209 Do not assume that EMACS_UINT is the same width as uprintmax_t,

6242 * w32.c (init_environment, get_emacs_configuration): Support AMD64
6244 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
6245 compatibility with x64.
6247 * vm-limit.c (lim_data): Now size_t.
6248 (check_memory_limits): Adjust prototypes of real_morecore and
6249 __morecore to receive argument of type ptrdiff_t. Use size_t for
6250 five_percent and data_size.
6252 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
6253 variables, for compatibility with x64.

6276 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows
6279 * image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since

6303 sigfillset, and sigprocmask are no longer no-ops.
6304 (sigismember): New function.
6305 (struct itimer_data): New definition.
6306 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)
6307 (crit_prof): New static variables.

6318 Windows-specific code to display the hourglass mouse pointer is no
6320 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
6321 to hourglass timer expiration.

6335 2012-09-30 Kenichi Handa <handa@gnu.org>
6337 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
6338 to the buffer relocation which may be caused by ccl_driver.

6395 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6397 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6398 HAVE_TIMER_SETTIME is defined.
6400 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6402 Profiler improvements: more-accurate timers, overflow checks.
6403 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6404 signal.h, setjmp.h. Include systime.h instead.
6405 (saturated_add): New function.
6406 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

6412 All uses changed to store the new value.
6413 (handle_profiler_signal): Rename from sigprof_handler_1,
6414 for consistency with other handlers. Do not check whether
6415 cpu_log is a hash-table if garbage collecting, since it
6416 doesn't matter in that case.
6417 (deliver_profiler_signal): Rename from sigprof_handler,
6418 for consistency with other handlers.
6419 (setup_cpu_timer): New function, with much of what used to be in
6420 Fprofiler_cpu_start. Check for out-of-range argument.
6421 Prefer timer_settime if available, and prefer
6422 thread cputime clocks, then process cputime clocks, then
6423 monotonic clocks, to the old realtime clock. Use make_timeval
6424 to round more-correctly when falling back to setitimer.
6425 (Fprofiler_cpu_start): Use it.
6426 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6427 Don't assume that passing NULL as the 2nd argument of setitimer
6428 is the same as passing a pointer to all-zero storage.
6429 Ignore SIGPROF afterwards.
6430 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6431 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6432 non-fatal signal handlers. Ignore SIGPROF on startup.
6433 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6434 in profiler.c, since sysdep.c now uses it.
6436 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

6474 * Makefile.in (LIB_TIMER_TIME): New macro.
6476 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
6477 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
6480 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
6482 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

6488 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
6490 * character.h (MAYBE_UNIFY_CHAR): Remove.
6491 * charset.c, charset.h (maybe_unify_char): Now static.
6492 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6493 Since this stuff is now private to charset.c, there's no need for
6494 a public macro and no need to inline by hand.
6496 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
6497 Stefan Monnier <monnier@iro.umontreal.ca>
6498 Juanma Barranquero <lekktu@gmail.com>

6523 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6525 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6527 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6529 Prefer POSIX timers if available.
6530 They avoid a race if the timer is too close to the current time.
6531 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6532 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6533 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6535 2012-09-25 Eli Zaretskii <eliz@gnu.org>

6540 STRING_CHAR_ADVANCE.
6542 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6544 Move Vlibrary_cache to emacs.c and reset before dumping.
6546 * lisp.h (reset_image_types): Declare.
6547 [WINDOWSNT] (Vlibrary_cache): Declare.
6549 * image.c (reset_image_types): New function.
6551 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

6558 * w32.h (Vlibrary_cache): Do not declare.
6560 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6562 * w32proc.c (sys_signal): Handle all signals defined by the
6563 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6564 handlers for signals supported by Windows. Don't override
6565 term_ntproc as the handler for SIGABRT.
6566 (sigaction): Rewrite to call sys_signal instead of duplicating its
6568 (sys_kill): Improve commentary.
6570 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6571 consistency with a signature of a signal handler. All callers
6573 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6574 install term_ntproc as a signal handler for SIGABRT, as that
6575 should be done by the dumped Emacs.
6577 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6579 * w32select.c (term_w32select): Protect against repeated
6580 invocation by setting clipboard_owner to NULL after calling
6583 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6584 and term_ntproc to their modified signatures.
6586 * character.c (char_string, string_char): Remove calls to
6587 MAYBE_UNIFY_CHAR. See the discussion starting at
6588 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6591 2012-09-25 Chong Yidong <cyd@gnu.org>
6593 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6595 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6597 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6598 when encountering an unknown bytecode.
6600 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6602 image.c, indent.c: Use bool for booleans.
6603 * dispextern.h (struct image_type): Members valid_p, load, init
6604 now return bool, not int. All uses changed.
6605 * image.c: Omit unnecessary static decls.
6606 (x_create_bitmap_mask, x_build_heuristic_mask):
6607 Return void, not int, since callers don't care about the return value.

6636 Use bool for booleans.
6638 2012-09-24 Chong Yidong <cyd@gnu.org>
6640 * chartab.c (Fset_char_table_default): Obsolete function removed.
6642 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6644 Move pid_t related decls out of lisp.h.
6645 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6646 (interruptible_wait_for_termination):
6647 Move these decls from lisp.h to syswait.h, since they use pid_t.
6648 Needed on FreeBSD; see Herbert J. Skuhra in
6649 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6650 * callproc.c: Include syswait.h.
6652 gnutls.c, gtkutil.c: Use bool for boolean.
6653 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)

6667 * nsmenu.m (ns_update_menubar):
6668 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6669 * xfns.c (Fx_show_tip) [USE_GTK]:
6670 Use bool for boolean.
6671 * gtkutil.c (xg_update_frame_menubar):
6672 * xmenu.c (update_frame_menubar):
6673 Return void, not int, since caller ignores return value.
6674 * gtkutil.c (xg_change_toolbar_position):
6677 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6679 * makefile.w32-in (BLOCKINPUT_H): Remove.

6696 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6698 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6699 fatal_error_backtrace.
6701 * w32proc.c (sys_kill): Undo last change: don't do anything when
6702 invoked to deliver SIGABRT to our own process. This is now
6703 handled by emacs_raise.
6705 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6707 * w32term.c (w32_read_socket): Remove leftover reference to
6708 interrupt_input_pending.
6710 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6712 Do not use SA_NODEFER.
6713 Problem reported by Dani Moncayo in
6714 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6716 * sysdep.c (emacs_abort): Do not reset signal handler.
6717 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6718 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6719 wanted even on POSIXish hosts, and it doesn't work on Windows.
6721 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6723 * xterm.c (x_term_init): Call fixup_locale before and after calling
6724 gtk_init (Bug#12392).
6726 2012-09-23 Chong Yidong <cyd@gnu.org>
6728 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6729 Vdynamic_library_alist.
6731 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6732 (Fgnutls_available_p): Caller changed.
6734 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6735 (Flibxml_parse_xml_region): Likewise.
6737 * dispextern.h (struct image_type): Remove arg from init function.
6739 * image.c (Finit_image_library, lookup_image_type)
6740 (define_image_type): Remove now-unneeded second arg.
6741 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6742 (init_tiff_functions, init_gif_functions, init_svg_functions):
6743 Arglist and w32_delayed_load calling convention changed.
6744 (gs_type): Remove init_gs_functions; there is no such function.
6745 (valid_image_p, make_image): Fix caller to lookup_image_type.
6747 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6749 Simplify and avoid signal-handling races (Bug#12471).
6751 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6752 Avoid recursive loop if there's a fatal error in the function itself.
6753 * atimer.c (pending_atimers):
6754 * blockinput.h: Don't include "atimer.h"; no longer needed.
6755 (interrupt_input_pending): Remove. All uses removed.
6756 pending_signals now counts both atimers and ordinary interrupts.
6757 This is less racy than having three separate pending-signal flags.
6758 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6760 Rename from their upper-case counterparts BLOCK_INPUT,
6761 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6762 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6763 This makes it easier to access volatile variables more accurately.
6764 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6765 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6766 that's more reliable if the code is buggy and sets
6767 interrupt_input_blocked to a negative value. All uses changed.
6768 * atimer.c (deliver_alarm_signal):
6769 Remove. No need to deliver this to the parent; any thread can
6770 handle this signal now. All uses replaced by underlying handler.
6771 * atimer.c (turn_on_atimers):
6772 * dispnew.c (handle_window_change_signal):
6773 * emacs.c (handle_danger_signal):
6774 * keyboard.c (kbd_buffer_get_event):
6775 Don't reestablish signal handler; not needed with sigaction.
6776 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6778 Rework to avoid unnecessary accesses to volatile variables.
6779 (UNBLOCK_INPUT_TO): Now a function.
6780 (totally_unblock_input, unblock_input): New decls.
6781 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6782 (init_data): Remove. Necessary stuff now done in init_signal.
6783 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6784 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6785 (fatal_error_code): Remove; no longer needed.
6786 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6787 it doesn't always backtrace. All uses changed. No need to reset
6788 signal to default, since sigaction and/or die does that for us now.
6789 Use emacs_raise (FOO), not kill (getpid (), FOO).
6790 (main): Check more-accurately whether we're dumping.
6791 Move fatal-error setup to sysdep.c
6792 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6793 * gtkutil.c (xg_get_file_name, xg_get_font):
6794 Remove no-longer-needed signal-mask manipulation.
6795 * keyboard.c, process.c (POLL_FOR_INPUT):
6796 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6797 * keyboard.c (read_avail_input): Remove.
6798 All uses replaced by gobble_input.
6799 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6800 (kbd_buffer_store_event_hold, gobble_input):
6801 (record_asynch_buffer_change) [USABLE_SIGIO]:
6802 (store_user_signal_events):
6803 No need to mess with signal mask.
6804 (gobble_input): If blocking input and there are terminals, simply
6805 set pending_signals to 1 and return. All hooks changed to not
6806 worry about whether input is blocked.
6807 (process_pending_signals): Clear pending_signals before processing
6808 them, in case a signal comes in while we're processing.
6809 By convention callers now test pending_signals before calling us.
6810 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6811 New functions, to support changes to blockinput.h.
6812 (handle_input_available_signal): Now extern.
6813 (reinvoke_input_signal): Remove. All uses replaced by
6815 (quit_count): Now volatile, since a signal handler uses it.
6816 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6817 All callers changed. Block SIGINT only if not already blocked.
6818 Clear sigmask reliably, even if Fsignal returns, which it can.
6819 Omit unnecessary accesses to volatile var.
6820 (quit_throw_to_read_char): No need to restore sigmask.
6821 * keyboard.c (gobble_input, handle_user_signal):
6822 * process.c (wait_reading_process_output):
6823 Call signal-handling code rather than killing ourselves.
6824 * lisp.h: Include <float.h>, for...
6825 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6826 (pending_signals): Now volatile.
6827 (syms_of_data): Now const if IEEE floating point.
6828 (handle_input_available_signal) [USABLE_SIGIO]:
6829 (terminate_due_to_signal, record_child_status_change): New decls.
6830 * process.c (create_process): Avoid disaster if memory is exhausted
6831 while we're processing a vfork, by tightening the critical section
6833 (send_process_frame, process_sent_to, handle_pipe_signal)
6834 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6836 (send_process): No need for setjmp/longjmp any more, since the
6837 SIGPIPE stuff is now gone. Instead, report an error if errno
6839 (record_child_status_change): Now extern. PID and W are now args.
6840 Return void, not bool. All callers changed.
6841 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6842 Remove. All uses removed. This bug should be fixed now in a
6844 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6845 and record the child status change directly. This avoids the
6846 need to futz with the signal mask.
6847 (process_fatal_action): Move here from emacs.c.
6848 (emacs_sigaction_flags): New function, containing
6849 much of what used to be in emacs_sigaction_init.
6850 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6851 caught by emacs, to make races less likely.
6852 (deliver_process_signal): Rename from handle_on_main_thread.
6854 (BACKTRACE_LIMIT_MAX): Now at top level.
6855 (thread_backtrace_buffer, threadback_backtrace_pointers):
6857 (deliver_thread_signal, deliver_fatal_thread_signal):
6858 New functions, for more-accurate delivery of thread-specific signals.
6859 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6860 (deliver_arith_signal): Handle in this thread, not
6861 in the main thread, since it's triggered by this thread.
6862 (maybe_fatal_sig): New function.
6863 (init_signals): New arg DUMPING so that we can be more accurate
6864 about whether we're dumping. Caller changed.
6865 Treat thread-specific signals differently from process-general signals.
6866 Block all signals while handling fatal error; that's safer.
6867 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6869 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6870 Ignore SIGPIPE unless batch.
6871 (emacs_backtrace): Output backtrace for the appropriate thread,
6872 which is not necessarily the main thread.
6873 * syssignal.h: Include <stdbool.h>.
6874 (emacs_raise): New macro.
6875 * xterm.c (x_connection_signal): Remove; no longer needed
6876 now that we use sigaction.
6877 (x_connection_closed): No need to mess with sigmask now.
6878 (x_initialize): No need to reset SIGPIPE handler here, since
6879 init_signals does this for us now.

6883 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6884 background rect may be larger (Bug#12245).
6886 2012-09-23 Chong Yidong <cyd@gnu.org>
6888 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6890 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6892 * .gdbinit: Just stop at fatal_error_backtrace.
6893 See Stefan Monnier's request in
6894 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6895 Remove no-longer-used query of system type.
6897 2012-09-22 Chong Yidong <cyd@gnu.org>
6899 * search.c (Freplace_match): Doc fix (Bug#12325).
6901 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6903 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6904 (Fline_end_position): Doc fix.
6906 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6908 2012-09-22 Chong Yidong <cyd@gnu.org>
6910 * dispextern.h (struct image_type): Add new slot, storing a type
6911 initialization function.
6913 * image.c (define_image_type): Call the image initializer function
6914 if it is defined. Arguments and return value changed.
6915 (valid_image_p, make_image): Callers changed.
6916 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6917 (gif_type, imagemagick_type, svg_type, gs_type):
6918 Add initialization functions.
6919 (Finit_image_library): Call lookup_image_type.
6920 (CHECK_LIB_AVAILABLE): Macro deleted.
6921 (lookup_image_type): Call define_image_type here, rather than via
6922 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6923 (syms_of_image): Move define_image_type calls for xbm_type and
6924 pbm_type to lookup_image_type.
6926 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6928 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6929 'idle_timers' from here ...
6930 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6931 lists, to avoid infloops when the timer does something stupid,
6932 like reinvoke itself with the same or smaller time-out.
6935 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6937 * window.c (Fsplit_window_internal): Handle only Qt value of
6938 Vwindow_combination_limit separately.
6939 (Qtemp_buffer_resize): New symbol.
6940 (Vwindow_combination_limit): New default value.
6943 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6945 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6946 the new overlay string. (Bug#10159)
6948 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6950 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6951 or that fprintf is async-signal-safe. POSIX doesn't require
6954 2012-09-22 Chong Yidong <cyd@gnu.org>
6956 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6959 2012-09-22 Kenichi Handa <handa@gnu.org>
6961 * composite.c (composition_reseat_it): Handle the case that a
6962 grapheme cluster is not covered by a single font (Bug#12352).
6964 2012-09-21 Chong Yidong <cyd@gnu.org>
6966 * image.c (define_image_type): Avoid adding duplicate types to
6967 image_types (Bug#12463). Suggested by Jörg Walter.
6969 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6971 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6972 (print_load_command_name): Add case LC_DATA_IN_CODE.
6973 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6975 2012-09-21 Glenn Morris <rgm@gnu.org>
6977 * eval.c (Frun_hook_with_args_until_success)
6978 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6980 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6982 * fileio.c (Ffile_selinux_context): Only call freecon when
6983 lgetfilecon succeeded.
6984 (Fset_file_selinux_context): Likewise. (Bug#12444)
6986 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6988 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6989 reordering, locate the cursor by calling set_cursor_from_row; if
6990 that fails, clear the desired glyph matrix before returning a
6991 failure indication to the caller. Fixes leaving garbled display
6992 when fast scrolling with a down-key. (Bug#12403)
6993 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6994 scrolling through multibyte text.
6996 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6998 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6999 calling mark_vectorlike since that's the one that marks the window.
7000 (mark_discard_killed_buffers): Mark the final cdr.
7001 * window.h (struct window): Move prev/next_buffers to the
7002 non-standard fields.
7003 * window.c (make_window): Initialize prev/next_buffers manually.
7005 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7007 Omit unused arg EXPECTED from socket hooks.
7008 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7009 * nsterm.m (ns_term_init):
7010 * termhooks.h (struct terminal.read_socket_hook):
7011 * w32inevt.c (w32_console_read_socket):
7012 * w32term.c (w32_read_socket):
7013 * xterm.c (XTread_socket):
7014 Omit unused arg EXPECTED. All callers changed.
7015 (store_user_signal_events): Return void, not int, since callers no
7016 longer care about the return value. All uses changed.
7018 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7020 * w32gui.h (XParseGeometry): Do not declare.
7022 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7024 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7025 Ignore 'expected'. See Eli Zaretskii in
7026 <http://bugs.gnu.org/12471#8> (last line).
7028 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7029 (XParseGeometry): Now static. Substitute extremal values for
7030 values that are out of range.
7032 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7034 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7036 * nsfns.m (XParseGeometry): Remove.
7037 (Fx_create_frame): Call x_set_offset to correctly interpret
7038 top_pos in geometry.
7040 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7041 (Fx_parse_geometry): If there is a space in string, call
7042 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7044 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7046 * search.c (scan_buffer): Use character positions in calls to
7047 region_cache_forward and region_cache_backward, not byte
7048 positions. (Bug#12196)
7050 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7051 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7053 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7054 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7055 emacs_blocked_malloc, now deleted.
7057 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7059 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7060 The workaround was for improving performance on Solaris 2.4, but
7061 is getting in the way now. Emacs will still work if someone is
7062 still running Solaris 2.4 in a museum somewhere; Sun dropped
7063 support for Solaris 2.4 in 2003.
7064 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7065 * process.c (create_process) [HAVE_WORKING_VFORK]:
7066 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7067 since Emacs no longer uses vfork on that platform.
7069 2012-09-17 Glenn Morris <rgm@gnu.org>
7071 * emacs.c: Use COPYRIGHT.
7073 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7075 Remove configure's --without-sync-input option (Bug#12450).
7076 When auditing signal-handling in preparation for cleaning it up,
7077 I found that SYNC_INPUT has race conditions and would be a real
7078 pain to fix. Since it's an undocumented and deprecated
7079 configure-time option, now seems like a good time to remove it.
7080 Also see <http://bugs.gnu.org/11080#16>.
7081 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7082 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7083 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7084 (malloc_hysteresis):
7085 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7086 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7087 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7088 (dont_register_blocks, bytes_used_when_reconsidered)
7089 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7090 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7091 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7092 Remove. All uses removed.
7093 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7094 implementation, one that depends on whether the new macro
7095 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7097 * atimer.c (run_timers, handle_alarm_signal):
7098 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7099 (handle_async_input, process_pending_signals)
7100 (handle_input_available_signal, init_keyboard):
7101 * nsterm.m (ns_read_socket):
7102 * process.c (wait_reading_process_output):
7103 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7104 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7106 * xterm.c (XTread_socket):
7108 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7109 * eval.c (handling_signal): Remove. All uses removed.
7110 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7111 All uses replaced with the SYNC_INPUT version.
7112 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7114 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7117 * font.c (Ffont_shape_gstring): Remove unused local.
7119 2012-09-16 Glenn Morris <rgm@gnu.org>
7121 * Makefile.in (clean): No longer run nextstep's clean.
7123 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7125 (ns-app): Move here from ns.mk, and simplify.
7126 (clean): Simplify nextstep entry.
7127 * ns.mk: Remove file.
7129 2012-09-17 Kenichi Handa <handa@gnu.org>
7131 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7132 not covert the last few charactes.
7134 2012-09-16 Kenichi Handa <handa@gnu.org>
7136 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7137 here, but just check the validity of glyphs in the glyph-string.
7139 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7141 * window.c (Fwindow_parameter, Fset_window_parameter):
7142 Accept any window as argument (Bug#12452).
7144 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7146 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7147 to ns_term_init to avoid memory leak.
7149 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7150 explicit retain/release.
7151 (ns_term_init): Only allow one display. Initialize outerpool and
7154 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7156 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7157 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7158 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7159 the Microsoft problem in a different way, by altering ../nt/config.nt.
7161 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7176 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7177 by lisp.h. This completes removal of setjmp.h inclusion
7178 erroneously announced in the previous commit. (Bug#12446)
7180 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7183 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7184 not defined as a macro. The latter happens on MS-Windows.
7187 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7189 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7190 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7191 Some instances of '#include <setjmp.h>' removed, if the
7192 only reason for the instance was because "lisp.h" was included.
7193 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7194 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7195 and _longjmp with the new symbols. Emacs already uses _setjmp if
7196 available, so this change affects only POSIXish hosts that have
7197 sigsetjmp but not _setjmp, such as some versions of Solaris and
7198 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7199 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7200 (png_load_body) [HAVE_PNG]:
7201 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7202 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7203 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7204 since PNG requires jmp_buf. This is the only exception to the
7205 general rule that we now use sys_setjmp and sys_longjmp.
7206 This exception is OK since this code does not change the signal
7207 mask or longjmp out of a signal handler.
7209 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7211 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7212 Include "syssignal.h", for 'main_thread'.
7214 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7216 Avoid out-of-range marker position (Bug#12426).
7217 * insdel.c (replace_range, replace_range_2):
7218 Adjust markers before overlays, as suggested by comments.
7219 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7220 Remove redundant check before calling offset_intervals.
7222 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7224 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7225 current buffer (Bug#12387).
7227 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7229 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7231 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7233 Use a more backwards-compatible timer format (Bug#12430).
7234 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7235 vector element, not from the 4th, since PSECS is now at the end.
7236 (Fcurrent_idle_time): Doc fix.
7238 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7240 Function to mark objects and remove killed buffers at once.
7241 * alloc.c (discard_killed_buffers): Rename to ...
7242 (mark_discard_killed buffers) ... new name. Add marking
7243 of remaining objects. Fix comment. Adjust users.
7244 (mark_object): Do not touch frame buffer lists here.
7245 * frame.c (delete_frame): Reset frame buffer lists here.
7247 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7249 Better workaround for GNOME bug when --enable-gcc-warnings.
7250 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7251 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7252 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7254 Simplify SIGIO usage (Bug#12408).
7255 The code that dealt with SIGIO was crufty and confusing, e.g., it
7256 played tricks like "#undef SIGIO" but these tricks were not used
7257 consistently. Simplify mostly by not #undeffing standard symbols,
7258 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7259 or not as we please) rather than "defined SIGIO" (standard symbol
7260 that we probably shouldn't #undef).
7261 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7262 Modules that need it can include it.
7263 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7264 * dispextern.h (ignore_sigio): New decl.
7265 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7266 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7267 * emacs.c (shut_down_emacs):
7268 * keyboard.c (kbd_buffer_store_event_hold):
7269 Use ignore_sigio rather than invoking 'signal' directly.
7270 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7272 (FIONREAD, SIGIO): Do not #undef.
7273 (tty_read_avail_input): Use #error rather than a syntax error.
7274 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7275 for I_PIPE, used by SETUP_SLAVE_PTY.
7276 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7277 * sysdep.c (croak): Remove; no longer needed. This bit of
7278 temporary code, with Fred N. Fish's comment that it's temporary,
7279 has been in Emacs since at least 1992!
7280 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7281 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7282 * syssignal.h (croak): Remove decl.
7283 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7284 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7285 now that we're termios-only.
7286 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7287 * term.c (dissociate_if_controlling_tty): Use #error rather than
7290 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7291 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7292 to work around GNOME bug 683906.
7293 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7294 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7295 This works around GCC bug 54561.
7297 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7299 More fixes for 'volatile' and setjmp/longjmp.
7300 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7301 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7302 (png_load_body) [HAVE_PNG]:
7303 (jpeg_load_body) [HAVE_JPEG]:
7304 New function, with most of the old parent function's body.
7305 (png_load) [HAVE_PNG]:
7306 (jpeg_load) [HAVE_JPEG]:
7307 Invoke the new function, to avoid longjmp munging our locals.
7308 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7309 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7310 longjmp is passed 2, as the C standard doesn't guarantee this.
7311 Instead, store the failure code into mgr->failure_code.
7313 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7315 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7316 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7317 (syms_of_keyboard): Remove support for unread-command-char.
7319 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7321 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7322 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7323 violation. (Bug#12426)
7325 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7327 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7329 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7331 * eval.c: Add `inhibit-debugger'.
7332 (Qinhibit_debugger): New symbol.
7333 (call_debugger): Bind it instead of Qdebug_on_error.
7334 (maybe_call_debugger): Test Vinhibit_debugger.
7335 (syms_of_eval): Define inhibit-debugger.
7336 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7337 (syms_of_xdisp): Remove inhibit-debug-on-message.
7339 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7341 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7342 If a nonvolatile local variable is written before a _longjmp to
7343 the frame containing the variable, and is read after the _longjmp,
7344 the value read is indeterminate. Some local variables of type
7345 'struct handler' and 'struct catchtag' are used in this way, so
7346 mark each of their slots as volatile if the slot can be set before
7347 _longjmp and read afterwards.
7348 * lisp.h (struct handler): var and chosen_clause are now volatile.
7349 (struct catchtag): val, next, and pdlcount are now volatile.
7351 * bidi.c (bidi_push_it, bidi_pop_it):
7352 * fns.c (copy_hash_table):
7353 * image.c (define_image_type):
7354 * keyboard.c (kbd_buffer_store_event_hold):
7355 * process.c (Fprocess_send_eof):
7356 * xfaces.c (x_create_gc) [HAVE_NS]:
7357 * xgselect.c (xg_select):
7358 Prefer assignment to memcpy when either will do.
7360 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7361 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7362 time an item is removed. No need to mark this function 'inline';
7363 the compiler knows better than we do.
7365 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7367 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7368 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7369 to change_frame_size (Bug#12388).
7370 (windowDidResize:): Pass YES to updateFrameSize.
7372 * nsterm.h: Add delay parameter to updateFrameSize.
7374 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7376 Discard killed buffers from deleted window and frame objects.
7377 This reduces an amount of references to killed buffers and
7378 helps GC to reclaim them faster.
7379 * alloc.c (discard_killed_buffers): New function.
7380 (mark_object): Use it for deleted windows and frames.
7381 (mark_object): If symbol's value is set up for a killed buffer
7382 or deleted frame, restore its global binding.
7383 * data.c (swap_in_global_binding): Add GC notice.
7384 (swap_in_symval_forwarding): Use convenient set_blv_where.
7385 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7386 * window.h: ... to here.
7388 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7390 Convenient macro to check whether the buffer is live.
7391 * buffer.h (BUFFER_LIVE_P): New macro.
7392 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7393 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7395 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7397 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7398 composition cases (Bug#12364).
7400 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7401 overhang of succeeding glyphs overlapping box cursor.
7403 * w32term.c (x_draw_glyph_string): Likewise.
7405 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7407 Simplify, document, and port floating-point (Bug#12381).
7408 The porting part of this patch fixes bugs on non-IEEE platforms
7409 with frexp, ldexp, logb.
7410 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7412 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7413 support, by removing commented-out code and briefly listing the
7414 C89 functions excluded. The commented-out stuff was confusing
7415 maintenance, e.g., we thought we needed cbrt but it was commented out.
7416 (logb): Remove decl; no longer needed.
7417 (isfinite): New macro, if not already supplied.
7418 (isnan): Don't replace any existing macro.
7419 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7420 are present on all C89 platforms.
7421 (Ffrexp): Do not special-case zero, as frexp does the right thing
7423 (Flogb): Do not use logb, as it doesn't have the desired meaning
7424 on hosts that use non-base-2 floating point. Instead, stick with
7425 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7426 frexp, to avoid getting an unspecified result.
7428 * xdisp.c (Qinhibit_debug_on_message): Now static.
7430 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7432 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7433 NSBezierPath (Bug#12131).
7435 2012-09-10 Chong Yidong <cyd@gnu.org>
7437 * fns.c (Fdelq, Fdelete): Doc fix.
7439 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7441 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7442 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7444 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7446 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7447 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7450 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7452 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7453 left fringe if the window has a left margin. This avoids leaving
7454 traces of the cursor because its leftmost pixel is not drawn over.
7456 * dispnew.c (update_window_line): When the left margin area of a
7457 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7458 that screen line. (Bug#12277)
7460 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7462 Assume C89 or later for math functions (Bug#12381).
7463 This simplifies the code, and makes it a bit smaller and faster,
7464 and (most important) makes it easier to clean up signal handling
7465 since we can stop worring about floating-point exceptions in
7466 library code. That was a problem before C89, but the problem
7467 went away many years ago on all practical Emacs targets.
7468 * data.c, image.c, lread.c, print.c:
7469 Don't include <math.h>; no longer needed.
7470 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7471 might be autoconfigured, as that never happens.
7473 * doprnt.c (DBL_MAX_10_EXP):
7474 * print.c (DBL_DIG):
7475 Remove. C89 or later always defines these.
7476 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7477 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7478 (arith_error, domain_error, domain_error2):
7479 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7480 no longer needed -- we simply return what C returns. All uses removed.
7481 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7483 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7484 Remove. All uses expanded, as these macros are no longer used
7485 more than once and are now more trouble than they're worth.
7486 (Ftan): Use tan, not sin / cos.
7487 (Flogb): Assume C89 frexp.
7488 (fmod_float): Assume C89 fmod.
7489 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7490 (init_floatfns): Remove. All uses removed.
7492 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7494 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7495 compositeToPoint for OSX < 10.6 (Bug#12390).
7497 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7499 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7500 This produces more-accurate results.
7502 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7504 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7505 changes (Bug#12088).
7507 2012-09-08 Chong Yidong <cyd@gnu.org>
7509 * syntax.c (Fstring_to_syntax): Doc fix.
7511 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7513 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7514 in the internal border.
7515 (x_set_window_size): Remove static variables and their usage.
7516 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7517 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7518 Remove fringe/internal border adjustment (Bug#11052).
7519 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7520 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7521 (ns_fix_rect_ibw): Remove.
7522 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7523 (ns_dumpglyphs_box_or_relief): Ditto.
7524 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7526 (ns_dumpglyphs_image): Ditto.
7527 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7529 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7530 their usage. Add fringe_extended_p and its use as in other terms.
7531 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7532 scroll bar was removed.
7533 (updateFrameSize): New function.
7534 (windowDidResize): Move code to updateFrameSize and call it.
7536 * nsterm.h (EmacsView): Add updateFrameSize.
7538 2012-09-07 Chong Yidong <cyd@gnu.org>
7540 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7542 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7544 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7546 More signal-handler cleanup (Bug#12327).
7547 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7548 Problem introduced when merging patches. Noted by Eli Zaretskii in
7549 <http://bugs.gnu.org/12327#67>.
7550 * floatfns.c: Comment fix.
7551 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7552 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7553 and anyway the declaration is harmless even if SIGDANGER is not defined.
7554 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7555 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7556 source files not surprisingly expected syssignal.h to define, or
7557 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7558 Include <sys/ioctl.h>, for FIONREAD.
7559 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7560 This eliminates a problem whereby other files mysteriously had
7561 to include "syssignal.h" before including "systty.h" if they
7562 wanted to use "#ifdef SIGIO".
7564 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7566 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7568 * w32.c (sigemptyset): Empty the set.
7569 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7571 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7573 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7575 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7576 (mark_object): Likewise for frame objects.
7578 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7580 * syssignal.h (handle_on_main_thread): Always declare,
7581 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7582 This ports to platforms without HAVE_PTHREAD.
7584 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7586 Signal-handler cleanup (Bug#12327).
7587 Emacs's signal handlers were written in the old 4.2BSD style with
7588 sigblock and sigmask and so forth, and this led to some
7589 inefficiencies and confusion. Rewrite these to use
7590 pthread_sigmask etc. without copying signal sets around. Also,
7591 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7592 'signal', and instead use functions that do not attempt to take
7593 over the system name space. This patch causes Emacs's text
7594 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7595 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7596 Do not include <signal.h> or "syssignal.h", as these
7597 modules do not use signals.
7598 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7599 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7600 Do not include <signal.h>, as "syssignal.h" does that for us now.
7601 * atimer.c (sigmask_atimers): New function.
7602 (block_atimers, unblock_atimers): New functions,
7603 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7605 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7606 no longer needed here.
7607 * emacs.c (main): Inspect existing signal handler with sigaction,
7608 so that there's no need to block and unblock SIGHUP.
7609 * sysdep.c (struct save_signal): New member 'action', replacing
7610 old member 'handler'.
7611 (save_signal_handlers, restore_signal_handlers):
7612 Use sigaction instead of 'signal' to save and restore.
7613 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7614 New function. All users of 'signal' modified to use set_sighandler
7615 if they're writeonly, and to use sys_signal if they're read+write.
7616 (emacs_sigaction_init, forwarded_signal): New functions.
7617 (sys_signal): Remove. All uses replaced by calls to sigaction
7618 and emacs_sigaction_init, or by direct calls to 'signal'.
7619 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7620 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7621 all uses replaced by pthread_sigmask etc. calls.
7622 * syssignal.h: Include <signal.h>.
7623 (emacs_sigaction_init, forwarded_signal): New decls.
7624 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7625 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7626 (sigmask, sys_sigmask): Remove; no longer needed.
7627 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7628 (sigblock, sigunblock, sigfree):
7629 (sigsetmask) [!defined sigsetmask]:
7630 Remove. All uses replaced by pthread_sigmask.
7631 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7632 no longer need to be replaced, and its typical old uses
7633 are now done via emacs_sigaction_init and sigaction.
7634 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7635 (sys_sigdel): Remove; unused.
7636 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7638 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7640 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7641 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7643 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7645 Explicitly mark buffer_defaults and buffer_local_symbols.
7646 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7647 mark_local_symbols here.
7648 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7649 since special buffers aren't marked here any more.
7650 (allocate_buffer): Chain new buffer with all_buffers here...
7651 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7653 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7654 (syms_of_buffer): Remove staticpro of the above.
7655 (init_buffer_once): Set names for buffer_defaults and
7656 buffer_local_symbols.
7658 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7660 Use bool for booleans in font-related modules.
7661 * font.c (font_intern_prop, font_style_to_value)
7662 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7663 (generate_otf_features, font_check_otf_features, font_check_otf)
7664 (font_match_p, font_list_entities, font_at):
7665 * fontset.c (fontset_id_valid_p, reorder_font_vector
7666 (fontset_find_font, Fset_fontset_font)
7667 (face_suitable_for_char_p) [0]:
7668 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7669 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7670 (m17n_flt_initialized, ftfont_shape_by_flt):
7671 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7672 * nsfont.m (nsfont_draw):
7673 * w32font.c (w32font_draw):
7674 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7675 Use bool for booleans.
7676 * font.h: Adjust to above API changes.
7677 (struct font, struct font_driver, struct font_driver_list):
7678 Use bool for booleans.
7679 (struct font): Remove useless member encoding_type.
7681 * fontset.c, xftfont.c: Omit unnecessary static decls.
7683 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7685 * alloc.c (mark_object): Revert window marking code
7686 since it's unsafe for the Fset_window_configuration.
7688 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7690 Fix race conditions with signal handlers and errno (Bug#12327).
7691 Be more systematic about preserving errno whenever a signal
7692 handler returns, even if it's not in the main thread. Do this by
7693 renaming signal handlers to distinguish between signal delivery
7694 and signal handling. All uses changed.
7695 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7696 * data.c (deliver_arith_signal): Rename from arith_error.
7697 * dispnew.c (deliver_window_change_signal): Rename from
7698 window_change_signal.
7699 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7700 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7701 * keyboard.c (deliver_input_available_signal): Rename from
7702 input_available_signal.
7703 (deliver_user_signal): Rename from handle_user_signal.
7704 (deliver_interrupt_signal): Rename from interrupt_signal.
7705 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7706 (deliver_child_signal): Rename from sigchld_handler.
7707 * atimer.c (handle_alarm_signal):
7708 * data.c (handle_arith_signal):
7709 * dispnew.c (handle_window_change_signal):
7710 * emacs.c (handle_fatal_signal, handle_danger_signal):
7711 * keyboard.c (handle_input_available_signal):
7712 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7713 * process.c (handle_pipe_signal, handle_child_signal):
7714 New functions, with the actual signal-handling code taken from the
7715 original respective signal handlers, sans the sporadic attempts to
7716 preserve errno, since that's now done by handle_on_main_thread.
7717 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7718 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7719 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7721 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7722 Move initialization of main_thread to sysdep.c's init_signals.
7723 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7724 our usage, and simplifies the mainline code.
7725 (record_child_status_change): New static function, as a helper
7726 for handle_child_signal, and with most of the old child handler's
7728 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7729 (handle_child_signal): Use the above.
7730 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7731 Moved here from emacs.c.
7732 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7733 code moved here from emacs.c's main function.
7734 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7735 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7736 This lets callers save and restore errno properly.
7738 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7740 Remove redundant or unused things here and there.
7741 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7742 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7743 * editfns.c (Fcompare_buffer_substrings): Likewise.
7744 * frame.h (struct terminal, struct font_driver_list):
7745 Remove redundant declarations.
7746 * window.h (Qleft, Qright): Likewise.
7748 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7750 Do not mark objects from deleted buffers, windows and frames.
7751 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7752 (mark_object): Likewise for windows and frames.
7754 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7756 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7757 buffer_defaults and buffer_local_symbols as valid objects.
7758 Return special value to denote them.
7760 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7762 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.

7764 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7765 (file_name_absolute_p, Fsubstitute_in_file_name):

7768 (Finsert_file_contents, choose_write_coding_system)
7769 (Fwrite_region, build_annotations, a_write, e_write)
7771 * filelock.c (boot_time_initialized, get_boot_time)
7772 (get_boot_time_1, lock_file_1, within_one_second):
7773 * floatfns.c (in_float):
7774 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7775 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7776 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7777 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7778 * window.c (compare_window_configurations):
7779 Use bool for booleans.
7780 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7781 (Fdefault_file_modes): Now mode_t, not int, for modes.
7782 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7783 (internal_delete_file): Now returns void, not a (boolean) int,
7784 since nobody was looking at the return value.
7785 * lisp.h, window.h: Adjust to above API changes.
7787 * xdisp.c (set_message): Simplify and reindent last change.
7789 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7791 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7793 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7795 * eval.c (call_debugger): Make the function non-static so that we
7796 can call it from set_message.
7798 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7799 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7801 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7803 Give more-useful info on a fatal error (Bug#12328).
7804 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7805 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7806 of doing the work ourselves.
7807 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7808 do most of the work.
7809 (fatal_error_backtrace): New function, taken from the guts
7810 of the old fatal_error_signal, but with a new option to output
7812 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7813 info about the signal than just its number.
7814 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7815 * sysdep.c: Include <execinfo.h>
7816 (emacs_backtrace): New function, taken partly from the previous
7817 code of the 'die' function.
7818 (emacs_abort): Call fatal_error_backtrace rather than abort.
7820 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7822 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7823 eager (load-time) macro-expansion.
7824 * lisp.mk (lisp): Add macroexp.
7826 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7828 Simplify redefinition of 'abort' (Bug#12316).
7829 Do not try to redefine the 'abort' function. Instead, redo
7830 the code so that it calls 'emacs_abort' rather than 'abort'.
7831 This removes the need for the NO_ABORT configure-time macro
7832 and makes it easier to change the abort code to do a backtrace.
7833 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7834 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7835 Remove; sysdep.c's emacs_abort now takes its place.
7836 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7837 'abort' changed to use 'emacs_abort'.
7838 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7839 (abort) [!defined abort]: Rename to ...
7840 (emacs_abort): ... new name.
7841 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7842 the place of the old 'abort' in emacs.c.
7843 * w32.c, w32fns.c (abort): Do not #undef.
7844 * w32.c (emacs_abort): Rename from w32_abort.
7846 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7848 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7849 offsets[j].dv, since the y axis of the screen coordinates points
7850 down, while the y axis of the font definition coordinates points
7851 up. This fixes display of Arabic diacritics such as KASRA and
7852 KASRATAN. (Bug#11860)
7854 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7856 Be more systematic about _setjmp vs setjmp.
7857 * alloc.c (test_setjmp, mark_stack):
7858 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7859 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7860 (png_load, my_error_exit, jpeg_load):
7861 * process.c (send_process_trap, send_process):
7862 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7863 The underscored versions are up to 30x faster on some hosts.
7864 Formerly, the code used setjmp+longjmp sometimes and
7865 _setjmp+_longjmp at other times, with no particular reason to
7866 prefer setjmp+longjmp.
7868 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7870 Fix minor problem found by static checking.
7871 * buffer.c (Fdelete_all_overlays): Return nil.
7873 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7875 * buffer.c (Fdelete_all_overlays): New function.
7877 2012-09-03 Chong Yidong <cyd@gnu.org>
7879 * gtkutil.c: Add extern decl for Qxft.
7881 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7883 * emacs.c, eval.c: Use bool for boolean.
7884 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

7895 All callers changed.
7896 * eval.c (interactive_p): Omit always-true boolean argument
7897 EXCLUDE_SUBRS_P. All callers changed.
7898 * dispextern.h, lisp.h: Reflect above API changes.
7899 * firstfile.c (dummy): Use the address of 'main', whose signature
7900 won't change, instead of the address of 'initialize', whose
7901 signature just changed from int to bool.
7902 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7903 * msdos.c (fatal_error_in_progress): ... from here.
7904 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7906 (redisplay_internal, unwind_redisplay): Simply clear
7907 REDISPLAYING_P when unwinding, instead of saving its previous,
7908 always-false value and then restoring it.
7910 Clean up some extern decls.
7911 Mostly, this hoists extern decls out of .c files and into .h files.
7912 That way, we're more likely to catch errors if the interfaces change.
7913 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7914 declare xg_mark_data.
7915 * dispextern.h (x_frame_parm_handlers):
7917 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7918 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

7933 * xfont.c (x_clear_errors):
7934 * xterm.c (x_frame_parm_handlers):
7935 Remove now-redundant extern decls.
7936 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7937 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7939 * xfaces.c: Remove unnecessary static decls.
7940 * xterm.c (updating_frame): Remove decl of nonexistent object.
7942 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7943 when building globals.h, as the objects that are not built on
7944 this host are not needed to compile C files on this host.
7946 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7948 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7975 (set_intervals_multibyte_1, set_intervals_multibyte):
7976 * keyboard.c (decode_timer):
7977 Use bool for boolean.
7978 * intervals.h, lisp.h, systime.h: Reflect above API changes.
7979 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
7981 2012-09-02 Chong Yidong <cyd@gnu.org>

7986 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7988 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7989 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7996 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7998 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7999 more than one grapheme cluster passed to the shaper: compute the
8000 offset adjustment values separately for each cluster. (Bug#11860)
8002 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8003 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8004 about implicit conversions from integer to pointer.
8006 2012-09-01 Daniel Colascione <dancol@dancol.org>
8008 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8009 system used too early.
8011 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8013 Better seed support for (random).

8054 * keyboard.c: Include TERM_HEADER instead of listing all possible
8055 window-system headers.
8057 * image.c: Include TERM_HEADER instead of listing all possible

8061 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8062 window system declarations.
8064 * frame.h: Move common functions here: set_frame_menubar,
8065 x_set_window_size, x_sync, x_get_focus_frame,
8066 x_set_mouse_position, x_set_mouse_pixel_position,
8067 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8091 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8093 Remove mark_ttys function and fix tty_display_info initialization.
8094 * lisp.h (mark_ttys): Remove prototype.
8095 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8096 to mark_ttys because all possible values of 'top_frame' slot are
8097 the frames which are reachable from Vframe_list.
8098 * term.c (mark_ttys): Remove.
8099 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8101 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8103 Change struct frame bitfields from unsigned char to unsigned.
8104 * frame.h (struct frame): Change type of 'display_preempted',

8106 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
8107 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
8108 bitfields from unsigned char to unsigned.

8123 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8124 for GCC 4.7.1 x86-64.
8126 2012-08-30 Glenn Morris <rgm@gnu.org>
8128 * lread.c (init_lread): For out-of-tree builds, only add the
8129 source directory's site-lisp dir to the load-path if it exists,
8130 consistent with in-tree builds. (Bug#12302)
8132 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8134 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

8144 (addSplit): Remove return self, declare return value as void.
8145 (clicked:): Remove return self, declare return value as void.
8146 Set dialog_return to button_values[seltag]. Code formatting change.

8148 Code formatting change.
8149 (timeout_handler:): Set timer_fired to YES.
8150 (runDialogAt:): Set timer_fired to NO.
8151 Handle click on close button as quit.
8153 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8154 Add window_closed and button_values. Add void as return value for
8155 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8156 Add process_dialog as new member.
8158 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8160 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

8226 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8227 * dispextern.h (struct composition_it): Use bool for boolean.
8228 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8229 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8230 * dired.c (file_name_completion):
8231 Use bool for boolean. (This was missed in an earlier change.)
8233 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8235 * window.c (Fset_window_configuration): Revert first part of
8238 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8240 * nsterm.h (NSPanel): New class variable dialog_return.
8242 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8243 Initialize dialog_return.
8244 (windowShouldClose:): Use stop instead of stopModalWithCode.
8245 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8246 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8248 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
8251 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
8253 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
8254 * composite.c (find_composition, composition_gstring_p)
8255 (composition_reseat_it, find_automatic_composition):
8256 * data.c (let_shadows_buffer_binding_p)
8257 (let_shadows_global_binding_p, set_internal, make_blv)
8258 (Fmake_variable_buffer_local, Fmake_local_variable)
8259 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
8260 (cons_to_signed, arith_driver):
8261 * dbusbind.c (xd_in_read_queued_messages):
8262 * dired.c (directory_files_internal, file_name_completion):
8263 Use bool for booleans.
8264 * dired.c (file_name_completion):
8265 * process.h (fd_callback):
8266 Omit int (actually boolean) argument. It wasn't being used.
8268 * composite.h, lisp.h: Reflect above API changes.
8270 * cmds.c, coding.c: Use bool for booleans.
8271 * cmds.c (move_point, Fself_insert_command):
8272 * coding.h (struct composition status, struct coding_system):
8273 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
8274 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
8275 (emacs_mule_char, decode_coding_emacs_mule)
8276 (encode_coding_emacs_mule, detect_coding_iso_2022)
8277 (decode_coding_iso_2022, encode_invocation_designation)
8278 (encode_designation_at_bol, encode_coding_iso_2022)
8279 (detect_coding_sjis, detect_coding_big5, decode_coding_sjis)
8280 (decode_coding_big5, encode_coding_sjis, encode_coding_big5)
8281 (detect_coding_ccl, encode_coding_ccl, decode_coding_raw_text)
8282 (encode_coding_raw_text, detect_coding_charset)

8289 (Funencodable_char_position, code_convert_region)
8290 (code_convert_string, code_convert_string_norecord)
8291 (Fset_coding_system_priority):
8292 * fileio.c (Finsert_file_contents):
8293 Use bool for booleans.
8294 * coding.h, lisp.h: Reflect above API changes.
8295 * coding.c: Remove unnecessary static function decls.
8296 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8297 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8298 not a boolean 'int', since callers never look at the return value.
8299 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8300 * coding.h (decoding_buffer_size, encoding_buffer_size)
8301 (emacs_mule_string_char): Remove unused extern decls.
8302 (struct iso_2022_spec, struct coding_system):
8303 Use 'unsigned int : 1' for boolean fields, since there's more than one.
8304 (struct emacs_mule_spec): Remove unused field 'full_support'.
8305 All initializations removed.
8306 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8308 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8310 Fix spare memory change (Bug#12286).
8311 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8312 (valid_lisp_object_p): Likewise.
8314 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8316 * window.c (Fset_window_configuration): Record any window's old
8317 buffer if it's replaced (see Bug#8789). If the new current
8318 buffer doesn't appear in the selected window, go to its old
8321 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8323 Special MEM_TYPE_SPARE to denote reserved memory.
8324 * alloc.c (enum mem_type): New memory type.
8325 (refill_memory_reserve): Use new type for spare memory.
8326 This prevents live_cons_p and live_string_p from incorrect
8327 detection of uninitialized objects from spare memory as live.
8329 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8332 * Makefile.in (.PHONY): versioclean -> versionclean.
8334 Remove unused external symbols.
8335 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8336 * window.c (Qwindow_valid_p, decode_valid_window):
8337 Now static, not extern.
8338 * data.c (Qinterval): Remove; unused.
8339 (syms_of_data): Do not define 'interval'.
8340 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8341 * window.h (decode_valid_window):
8344 * character.c, charset.c, chartab.c: Use bool for booleans.
8345 * character.c (lisp_string_width, string_count_byte8)
8346 (string_escape_byte8):
8347 * charset.c (charset_map_loaded, load_charset_map, read_hex):
8348 (load_charset_map_from_file, map_charset_chars)
8349 (Fdefine_charset_internal, define_charset_internal)
8350 (Fdeclare_equiv_charset, find_charsets_in_text)
8351 (Ffind_charset_region, char_charset, Fiso_charset):
8352 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
8353 (sub_char_table_set, sub_char_table_set_range)
8354 (char_table_set_range, optimize_sub_char_table)
8355 (map_sub_char_table):
8356 Use bool for boolean.
8357 * character.c (str_to_unibyte): Omit last boolean argument; it was
8358 always 0. All callers changed.
8359 * character.h, charset.h: Adjust to match previous changes.
8360 * character.h (char_printable_p): Remove decl of nonexistent function.
8361 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8362 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8363 are all boolean, so make them single-bit bitfields.
8365 * lisp.h (ASET): Remove attempt to detect side effects.
8366 It was meant to be temporary and it often doesn't work,
8367 because when IDX has side effects the behavior of IDX==IDX
8368 is undefined. See Stefan Monnier in
8369 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8371 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8373 * lisp.h (functionp): New function (extracted from Ffunctionp).
8374 (FUNCTIONP): Use it.
8375 * eval.c (Ffunctionp): Use it.
8377 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8379 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8380 as that's faster and simpler than static storage. Don't bother
8381 with the g_main_context_query overhead if g_main_context_pending
8382 says no events are pending.
8383 (gfds, gfds_size): Remove these static vars.
8384 (xgselect_initialize): Remove; no longer needed.
8385 All uses and decls removed.
8387 * emacs.c (fatal_error_signal_hook): Remove.
8388 All uses removed. This leftover from old code was always 0.
8390 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8391 * casefiddle.c (casify_object, casify_region):
8392 * casetab.c (set_case_table):
8393 * category.c, category.h (word_boundary_p):
8394 * category.h (CHAR_HAS_CATEGORY):
8395 Use bool for booleans, instead of int.
8397 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8399 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8401 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8403 On assertion failure, print backtrace if available.
8404 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8405 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8406 * Makefile.in (LIB_EXECINFO): New macro.
8409 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8410 * bytecode.c (exec_byte_code):
8411 * callint.c (check_mark, Fcall_interactively):
8412 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8413 (getenv_internal, sync_process_alive, call_process_exited):
8414 * lisp.h (USE_SAFE_ALLOCA):
8415 Use bool for booleans, instead of int.
8416 * lisp.h, process.h: Adjust prototypes to match above changes.
8417 * callint.c (Fcall_interactively): Don't assume the mark's
8418 offset fits in 'int'.
8420 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8422 * buffer.c, buffer.h: Use bool for boolean.
8423 * buffer.c (reset_buffer_local_variables)
8424 (buffer_lisp_local_variables, Fset_buffer_modified_p)
8425 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
8426 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
8427 (overlay_touches_p, overlay_strings, Foverlay_put)
8428 (report_overlay_modification, call_overlay_mod_hooks):
8429 (mmap_enlarge, mmap_set_vars):
8430 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8431 Use bool for booleans, instead of int.
8432 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8433 since the 1-or-0 return value is always ignored anyway.
8434 (mmap_initialized_p):
8435 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8436 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8438 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8440 * bidi.c: Use bool for boolean.
8441 This is a bit more readable, and makes the text segment of bidi.o
8442 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8443 Presumably it's faster too.
8444 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8446 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8447 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8448 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8449 (bidi_explicit_dir_char, bidi_level_of_next_char)
8450 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8451 Use bool for booleans, instead of int.
8452 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8453 (bidi_unshelve_cache): Adjust decls to match code.
8455 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8457 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8460 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8462 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8463 * atimer.h: Include <stdbool.h>.
8465 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8467 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8468 compile time tests instead of run time tests on systems that do
8470 (FRAME_MAC_P): Remove leftover from deleted code.
8471 * frame.c (syms_of_frame): Remove leftover from deleted code.
8473 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8475 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8477 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8479 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8480 Otherwise, the compiler complains about (A?B:C) where B is void
8481 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8482 (fontset_add): Return void, for FONTSET_ADD.
8484 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8486 * alloc.c: Use bool for booleans.
8487 (gc_in_progress, abort_on_gc)
8488 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8489 (dont_register_blocks) [GC_MALLOC_CHECK]:
8490 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8491 (check_string_bytes, make_specified_string, memory_full)
8492 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8493 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8494 (mark_stack, valid_pointer_p, make_pure_string)
8495 (Fgarbage_collect, survives_gc_p, gc_sweep):
8496 Use bool for booleans, instead of int.
8497 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8498 Remove unused local.
8499 * alloc.c (PURE_POINTER_P):
8500 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8501 * editfns.c (Fformat):
8502 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8504 * fns.c (sweep_weak_table):
8505 * lisp.h (suppress_checking, push_message, survives_gc_p)
8506 (make_pure_string, gc_in_progress, abort_on_gc):
8507 * lread.c (readchar, read1):
8508 * print.c (Fprin1_to_string):
8509 * xdisp.c (push_message):
8510 Use bool for booleans affected directly or indirectly by
8513 Make recently-introduced setters macros.
8514 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8515 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8516 (set_fontset_default, set_fontset_fallback): Rename from their
8517 upper-case counterparts, and make them functions rather than macros.
8518 This is more consistent with the other recently-introduced setters.
8519 These don't need to be inline, since they're local.
8521 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8523 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8524 the loop (Bug#12247).
8526 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8528 * lisp.h (vcopy): Use memcpy rather than our own loop.
8529 This fixes a performance regression introduced by the recent
8530 addition of vcopy. This means 'vcopy' will need to be modified
8531 for a copying collector, but that's OK. Also, tighten the
8532 checking in the assertion.
8534 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8536 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8537 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8538 non-base glyph for the width of the base character, according to
8539 what x_draw_composite_glyph_string_foreground expects.
8540 Generate WADJUST value according to composition_gstring_width's
8541 expectations, to produce correct width of the composed character.
8542 Reverse the sign of the DU offset produced by ScriptPlace.
8544 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8546 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8548 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8550 Avoid direct writes to contents member of struct Lisp_Vector.
8551 * lisp.h (vcopy): New function to copy data into vector.
8552 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8553 * fns.c (Ffillarray): Use ASET.
8554 * keyboard.c (timer_check_2): Use AREF and ASET.
8555 (append_tool_bar_item, Frecent_keys): Use vcopy.
8556 * lread.c (read_vector): Use ASET.
8557 * msdos.c (Frecent_doskeys): Use vcopy.
8558 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8559 (Finternal_merge_in_global_face): Use ASET and vcopy.
8560 * xfont.c (xfont_list_pattern): Likewise.
8562 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8564 * window.c (Fwindow_point): For the selected window always return
8565 the position of its buffer's point.
8566 (Fset_window_point): For the selected window always go in its
8567 buffer to the specified position.
8569 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8571 Setter macros for fontsets.
8572 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8573 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8574 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8577 2012-08-20 Glenn Morris <rgm@gnu.org>
8579 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8580 Don't assume that `ln -f' works.
8582 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8584 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8585 and later about non-assignments with no effect. See discussion at
8586 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8589 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8591 Inline setter functions for Lisp_Objects slots of struct specbinding.
8592 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8595 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8597 * window.c (select_window): Always make selected window's buffer
8600 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8602 Use AREF and ASET for docstrings of category tables.
8603 * category.h (CATEGORY_DOCSTRING): Use AREF.
8604 (SET_CATEGORY_DOCSTRING): Use ASET.
8605 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8607 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8609 Inline setter functions for hash table members.
8610 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8611 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8612 (set_hash_key_and_value, set_hash_index, set_hash_next)
8613 (set_hash_hash): New functions.
8614 * charset.c, fns.c: Adjust users.
8616 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8618 Inline getter and setter functions for per-buffer values.
8619 * buffer.h (per_buffer_default, set_per_buffer_default)
8620 (per_buffer_value, set_per_buffer_value): New functions.
8621 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8622 * buffer.c, data.c: Adjust users.
8624 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8626 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8628 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8630 Rely on <config.h> + <unistd.h> to declare 'environ',
8631 as gnulib does this if the system doesn't.
8632 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8633 Remove declaration. MS-Windows declares it on stdlib.h which is
8634 included by conf_post.h.
8635 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8636 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8637 * vm-limit.c: Include <unistd.h>, for 'environ'.
8639 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8640 (start_of_data): Remove decl; mem-limits.h provides it.
8642 * xdisp.c (handle_invisible_prop): Make it a bit faster
8643 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8645 2012-08-19 Chong Yidong <cyd@gnu.org>
8647 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8650 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8652 * .gdbinit: Use call instead of set when calling a function in the
8655 * data.c (set_internal): Don't use set_blv_found.
8656 (Fkill_local_variable): Likewise.
8658 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8660 * nsfont.m (ns_ascii_average_width): Ensure the string
8661 ascii_printable is initialized with a null-terminated character
8662 array. Otherwise, it can contain undesired extra characters.
8664 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8666 port new setting code to Sun C 5.8 2005/10/13
8667 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8668 Return void, not Lisp_Object. Otherwise, the compiler
8669 complains about (A?B:C) where B is void and C is Lisp_Object

9538 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
9539 Now constants, not macros.
9541 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9543 Remove unnecessary casts involving pointers.
9544 These casts are no longer needed now that we assume C89 or later,
9545 since they involve casting to or from void *.
9546 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
9547 (make_pure_float, make_pure_vector):
9548 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9552 * sysdep.c (closedir):
9553 * xdisp.c (x_produce_glyphs):
9554 * xfaces.c (compare_fonts_by_sort_order):
9555 * xfns.c (x_real_positions, select_visual):
9556 * xselect.c (x_stop_queuing_selection_requests)
9557 (x_get_window_property, x_get_window_property_as_lisp_data):
9558 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9559 Remove unnecessary pointer casts.
9560 * alloc.c (record_xmalloc): New function.
9561 * lisp.h (record_xmalloc): New decl.
9562 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9563 more like a function. This is because the pointer cast is not
9564 needed. All uses changed.
9565 * print.c (print_string, print_error_message): Avoid length recalc.
9567 Improve fix for macroexp crash with debugging (Bug#12118).
9568 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9569 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9570 not supposed to be invoked from the garbage collector.
9571 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9572 (gc_aset): New function, which is like ASET but can be
9573 used in the garbage collector.
9574 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
9575 (set_hash_index): Use it instead of ASET.
9577 2012-08-03 Eli Zaretskii <eliz@gnu.org>

9586 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
9587 (map_w32_filename): Improve commentary. Simplify switch.
9588 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
9589 headers (most versions of MinGW w32api don't).
9590 (get_security_info, create_symbolic_link)
9591 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9593 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9594 in the argument file name.

9597 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9598 have the required privileges.
9599 (get_file_security_desc_by_name): Rename from
9600 get_file_security_desc.
9601 (stat_worker): New function, with most of the guts of 'stat', and
9602 with addition of handling of symlinks and support for 'lstat'.
9603 If possible, get file's attributes and security information by
9604 handle, not by name. Produce S_IFLNK bit for symlinks, when
9605 called from 'lstat'.
9606 (stat, lstat): New functions, call 'stat_worker'.
9607 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9608 symlinks when the underlying filesystem supports them.
9610 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9612 Fix macroexp crash on Windows with debugging (Bug#12118).
9613 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9614 checking subscripts; problem introduced with the recent
9615 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9616 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9617 since it's used in non-static inline functions now.
9619 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9620 Don't assume buffer size fits in 'int'. Remove unused local.
9622 Use C99-style 'extern inline' if available.

9631 New macro, replacing 'static inline' in this header.
9632 * buffer.h, category.h, character.h, charset.h, composite.h:
9633 * dispextern.h, lisp.h, systime.h:
9634 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
9635 * alloc.c (LISP_INLINE):
9636 * buffer.c (BUFFER_INLINE):
9637 * category.c (CATEGORY_INLINE):
9638 * character.c (CHARACTER_INLINE):
9639 * charset.c (CHARSET_INLINE):
9640 * composite.c (COMPOSITE_INLINE):
9641 * dispnew.c (DISPEXTERN_INLINE):
9642 * sysdep.c (SYSTIME_INLINE):
9643 Define to EXTERN_INLINE, so that the corresponding functions
9644 are compiled into code.
9645 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9646 (INLINE_HEADER_END): New macros.
9647 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
9648 since it's used in non-static inline functions now.

9667 hard-coding the path separator.
9669 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9671 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9672 This how ASET and AREF are supposed to work, and makes
9673 it easier to think about future improvements. See
9674 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9675 * charset.h (set_charset_attr): New function.
9676 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
9677 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

9934 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

10092 with other headers and sources, such as gmalloc.c and the
10093 MS-Windows system headers. All users changed.

10111 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10112 arms of an 'if', not using conditional expressions; otherwise GDB
10113 complains about the types in the unevaluated arm when the argument
10114 is an integer literal.
10115 (xgetint): Simplify expression.
10116 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10117 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10118 Zaretskii in <http://bugs.gnu.org/12036#13>.
10119 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10120 needed now that we have gdb_make_enums_visible.
10121 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10122 (enum enum_USE_LSB_TAG):
10123 New enum types, packaging up enums that need to be exported to GDB.
10125 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10127 Utility function to make a list from specified amount of objects.

10149 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10150 to deal with it. Adjust comments.
10151 (init_marker, attach_marker): New prototype.
10152 (unchain_marker): Adjust prototype.

10165 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10166 emacs.c, as this is a more-suitable home. Had this been done earlier
10167 the fix for 12036 would have avoided some of the problems noted in
10168 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10169 would have been more obvious.
10170 * emacs.c: Do not include <verify.h>; no longer needed.
10171 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

10179 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10180 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10181 not be usable in #if. This simplifies things.
10183 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10185 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10187 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

10190 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10191 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10192 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10193 Adjust to changes in lisp.h and emacs.c, by using
10194 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10195 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10196 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10197 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10198 instead of gdb_valbits.
10199 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10200 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10201 instead of gdb_array_mark_flag.
10202 (xboolvector): Get size from $->size, not $->header.size.
10203 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10204 (xreload, hook-run, hookpost-run): Remove.
10205 * emacs.c: Include <verify.h>.
10206 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10207 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10209 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10210 (gdb_USE_LSB_TAG): New enum constants.
10211 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10212 Also define these as enum constants, so they're visible to GDB.
10213 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10214 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10215 as constants, so they're visible to GDB.
10216 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10217 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10218 Now enum constants, not macros, so they're visible to GDB.
10219 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10220 more convenient now. All uses changed.
10221 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10222 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

10232 add argument, tune behavior, and adjust all callers.
10234 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10236 Use typedef for EMACS_INT, EMACS_UINT.
10237 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10238 than macros. This simplifies debugging in the usual case, since
10239 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10240 and it allows expressions involving EMACS_INT casts.
10241 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10243 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10245 * nsterm.m (ns_read_socket): Return early if there is a modal

10251 that FOCUS-FRAME can be omitted.
10253 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10255 Adjust buffer text indirection counters at the end of Fkill_buffer.
10256 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10257 buffer is definitely dead. This should really fix an issue reported
10258 by Christoph Scholtes again. (Bug#12007).
10259 (init_buffer_once): Initialize indirection counters of
10260 buffer_defaults and buffer_local_symbols (for sanity and safety).
10262 2012-07-24 Eli Zaretskii <eliz@gnu.org>

10277 or invalid. (Bug#12025)
10279 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10280 it signals an error when a tooltip frame is being created.
10282 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10284 Cleanup miscellaneous objects allocation and initialization.
10285 * alloc.c (allocate_misc): Change to static. Add argument to
10286 specify the subtype. Adjust comment and users.
10287 (build_overlay): New function.
10288 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10289 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
10290 (allocate_misc): Remove prototype.
10291 (build_overlay): Add prototype.
10293 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10295 Swap buffer text indirection counters in Fbuffer_swap_text.
10296 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10297 This avoids crash reported by Christoph Scholtes at
10298 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10300 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10302 * nsmenu.m (Popdown_data): New struct.
10303 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
10305 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
10306 (initWithContentRect): Make imgView and contentView non-static
10307 and autorelease them. Also autorelease img and matrix (Bug#12005).
10308 (dealloc): Remove (Bug#12005).
10310 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10312 Adjust consing_since_gc when objects are explicitly freed.
10313 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.

10323 (set_marker_both, set_marker_restricted_both): Use live_buffer.
10325 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
10327 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
10328 as it's limited by the amount of memory, not by INT_MAX.
10330 2012-07-21 Eli Zaretskii <eliz@gnu.org>
10332 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

10379 (memory_full_cons_threshold): Revert declaration.
10380 (maybe_gc): Remove prototype, define as inline.
10381 * alloc.c: Remove old commented-out code.

11056 * s/aix4-2.h (unix): Remove; no longer needed.
11058 EMACS_TIME simplification (Bug#11875).
11059 This replaces macros (which typically do not work in GDB)
11060 with functions, typedefs and enums, making the code easier to debug.
11061 The functional style also makes code easier to read and maintain.
11062 * systime.h: Include <sys/time.h> on all hosts, not just if
11063 WINDOWSNT, since 'struct timeval' is needed in general.
11064 (EMACS_TIME): Now a typedef, not a macro.

11067 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

11098 (menu_separator_name_p):
11099 * nsmenu.m (ns_update_menubar):
11100 Prefer memcmp to strncmp when either will do.
11101 * nsterm.m: Include <ftoastr.h>.
11103 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11104 Prefer snprintf to strncpy.
11105 * nsterm.m (ns_term_init):
11106 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11107 * nsterm.m (ns_term_init):
11108 Avoid the need for strncpy, by using build_string or
11109 make_unibyte_string directly. Use dtoastr, not snprintf.
11110 * process.c (Fmake_network_process): Diagnose service names that
11111 are too long, rather than silently truncating them or creating
11112 non-null-terminated names.
11113 (Fnetwork_interface_info): Likewise, for interface names.
11114 * sysdep.c (system_process_attributes) [GNU_LINUX]:
11115 Prefer sprintf to strncat.
11116 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
11117 Prefer vsnprintf to vsprintf + strncpy.

11147 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11148 argument, adjust users accordingly. Use build_pure_c_string where

11151 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11152 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

11182 We include usg5-4-common.h, which defines them both.
11184 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11185 O_RDONLY already includes it).
11187 Stop ns builds setting the EMACSLOADPATH environment variable.
11188 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11189 Now it does not set EMACSLOADPATH, just returns the load-path string.
11190 * nsterm.h: Update accordingly.
11191 * lread.c [HAVE_NS]: Include nsterm.h.
11192 (init_lread) [HAVE_NS]: Use ns_load_path.

11202 (ns_init_paths): Do not set EMACSPATH.

11258 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11260 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11262 Move marker debugging code under MARKER_DEBUG.
11263 * marker.c (MARKER_DEBUG): Move marker debugging code under
11264 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11265 for bootstrap with --enable-checking (~3x slowdown reported
11266 by Juanma Barranquero <lekktu@gmail.com>).
11267 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11269 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11271 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11272 See <http://bugs.gnu.org/11825#29>.
11274 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11276 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11277 has no font, use the frame's font. (Bug#11813)
11278 (display_line): Add commentary about displaying truncation glyphs
11280 (produce_special_glyphs): Move here from term.c.
11282 * term.c (produce_special_glyphs): Move to xdisp.c.
11284 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11287 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11289 * xdisp.c (display_line): Avoid warning about implicit declaration
11292 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11294 * lisp.h: Remove empty conditional.
11296 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11298 * lread.c (load_path_check): Now static.
11300 Fix some minor --with-ns problems found by static checking.
11301 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11302 (x_set_font) [!HAVE_X_WINDOWS]:
11303 * image.c (xpm_load_image) [HAVE_NS]:
11304 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11305 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11306 Remove unused local.
11307 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11308 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11309 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11310 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11311 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11312 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11313 Fix pointer signedness problem.
11314 * xfaces.c (FRAME_X_FONT_TABLE):
11315 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11317 2012-07-07 Glenn Morris <rgm@gnu.org>
11319 * lread.c (load_path_check): New function, split from init_lread.
11320 (init_lread): Reorganize. Motivation:
11321 If EMACSLOADPATH is set, check/warn about that rather than the
11322 defaults, which we are not going to use. Hence we can remove
11323 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11324 Don't warn if site-lisp directories are missing.
11325 If not installed, start from a blank load-path, since
11326 PATH_LOADSEARCH refers to the eventual installation directories.
11328 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11330 Support truncation and continuation glyphs on GUI frames, when
11331 fringes are disabled. (Bug#11832)
11332 * xdisp.c (init_iterator): Get dimensions of truncation and
11333 continuation glyphs even if on GUI frames.
11334 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11335 or both, are absent.
11336 (start_display, move_it_in_display_line_to): Handle the case of a
11337 GUI frame without a fringe to display continuation or truncation
11339 (insert_left_trunc_glyphs): Support GUI frames: make sure
11340 truncation glyphs overwrite enough glyphs from the current line to
11341 have sufficient space in pixels.
11342 (display_line): Support truncation and continuation glyphs on GUI
11343 frames. If some spare pixels are left on the line after inserting
11344 the truncation glyphs, fill that space with a stretch glyph of a
11345 suitably computed width.
11347 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11348 produce_glyphs, to support GUI sessions.
11350 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11352 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11354 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11356 Do not require float-time's arg to fit in time_t (Bug#11825).
11357 This works better on hosts where time_t is unsigned, and where
11358 float-time is applied to the (negative) difference between two times.
11359 * editfns.c (decode_time_components): Last arg is now double *,
11360 not int *, and means to store all the result as a double, without
11361 worrying about whether the seconds part fits in time_t.
11362 All callers changed.
11363 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11364 All callers changed.
11365 (Ffloat_time): Do not fail merely because the specified time falls
11366 outside of time_t range.
11368 2012-07-07 Glenn Morris <rgm@gnu.org>
11370 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11371 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11372 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11374 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11376 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11377 Update dependencies.
11379 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11381 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11383 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
11384 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
11385 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11386 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11387 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11388 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11390 * xfont.c (compare_font_names): Redo to omit the need for casts.
11392 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11394 * xfns.c (Fx_change_window_property): Doc fix.
11395 * w32fns.c (Fx_change_window_property): Doc fix.
11397 * w32fns.c (Fx_window_property): Accept the same arguments as the
11398 X Windows version. Doc fix.
11399 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11401 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11402 Eli Zaretskii <eliz@gnu.org>
11404 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11405 Windows-specific code from nt/config.nt moved here.
11406 Obsolete settings removed.
11408 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11410 * process.c: Avoid unnecessary calls to gettime.
11411 (wait_reading_process_output): Don't get the time of day
11412 when gobbling data immediately and not waiting, as there's no need
11413 for it in that case. This removes a FIXME.
11415 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11417 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11418 is defined (Bug#11768).
11420 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11422 Fix marker debugging code.
11423 * marker.c (byte_char_debug_check): Do not perform the check
11424 if buffer is not multibyte.
11425 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11426 Call byte_char_debug_check with correct arguments.
11428 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11430 Compile marker debugging code only if ENABLE_CHECKING is defined.
11431 * marker.c (byte_char_debug_check, count_markers):
11432 Use only if ENABLE_CHECKING is defined.
11433 (byte_debug_flag): Remove.
11434 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11435 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11437 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11439 Avoid code repetition in marker-related functions.
11440 * marker.c (attach_marker): New function.
11441 (Fset_marker, set_marker_restricted, set_marker_both)
11442 (set_marker_restricted_both): Use it.
11443 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
11444 Consistently rename charno to charpos.
11445 (marker_position): Add eassert.
11446 (marker_byte_position): Convert to eassert.
11448 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11450 Simplify list operations in unchain_overlay and unchain_marker.
11451 * buffer.c (unchain_overlay): Simplify. Add comment.
11452 * marker.c (unchain_marker): Simplify. Fix comments.
11454 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11456 Introduce fast path for the widely used marker operation.

11459 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
11460 * composite.c (autocmp_chars): Likewise.
11461 * editfns.c (buildmark): Remove.
11462 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11463 (save_restriction_save): Use build_marker.
11464 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11465 * window.c (save_window_save): Likewise.
11467 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11469 Do not use Fdelete_overlay in delete_all_overlays
11470 to avoid redundant calls to unchain_overlay.
11471 * buffer.c (drop_overlay): New function.
11472 (delete_all_overlays, Fdelete_overlay): Use it.
11473 * minibuf.c (get_minibuffer): Fix comment.
11475 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11477 Port to OpenBSD 5.1 amd64.
11478 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11479 This is needed for OpenBSD, and should be harmless on all BSD systems.
11480 Also, include <sys/sysctl.h>, as it should be available on all
11481 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11482 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11483 use p_pid member, not kp_proc.pid.
11485 2012-07-06 Glenn Morris <rgm@gnu.org>
11487 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11489 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11491 More xmalloc and related cleanup.
11492 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11493 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
11494 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

11500 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11502 Omit needless casts involving void * pointers and allocation.
11503 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11504 as the former is more robust if P's type is changed.
11505 Prefer xzalloc to xmalloc + memset 0.
11506 Simplify malloc-or-realloc to realloc.
11507 Don't worry about xmalloc returning a null pointer.
11508 Prefer xstrdup to xmalloc + strcpy.
11509 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11511 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11512 alloca of a constant.
11514 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11516 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11517 hscroll is larger than the line width. Fixes long and futile
11518 looping inside extend_face_to_end_of_line (on a TTY) producing
11519 glyphs that are not needed and thrown away.
11521 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11523 * marker.c (set_marker_restricted_both): Simplify by using
11526 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11528 * editfns.c (region_limit): Simplify by using clip_to_bounds.

11535 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
11536 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
11537 followed by gtk_box_set_homogeneous (Bug#11768).
11538 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11539 (update_theme_scrollbar_width, xg_create_scroll_bar):
11540 Use gtk_scrollbar_new (Bug#11768).
11541 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11542 (is_box_type): New function (Bug#11768).
11543 (xg_tool_item_stale_p): Call is_box_type.
11544 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11545 with default display (Bug#11768).
11547 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11549 * xdisp.c (window_hscroll_limited): New function.
11550 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11551 coordinates when window's hscroll is set to insanely large
11552 values. (Bug#11857)
11554 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11556 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

11615 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11617 * fileio.c (time_error_value): Check the right error number.
11618 Problem reported by Troels Nielsen in
11619 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11621 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11623 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11624 This should be fixed in a better way; see Eli Zaretskii in
11625 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11626 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11628 * fileio.c (time_error_value): Rename from special_mtime.
11629 The old name's problems were noted by Eli Zaretskii in
11630 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11632 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11633 This variable's comment says Emacs needs at least one GDB-visible
11634 symbol of type enum pvec_type, to work around GDB problems.
11635 The symbol's value doesn't matter.
11637 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11638 that causes compilation to fail on pre-C99 compilers.
11640 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11642 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11643 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11645 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11647 * buffer.c (init_buffer_once): Fix initialization of
11648 headers for buffer_defaults and buffer_local_symbols.
11649 Reported by Juanma Barranquero <lekktu@gmail.com>.
11651 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11653 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11654 * lisp.h (enum pvec_type): Use fewer bits.
11655 (PSEUDOVECTOR_SIZE_BITS): New constant.
11656 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11657 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11658 change in pvec_type.
11659 (PSEUDOVECTOR_TYPEP): New macro.
11660 (TYPED_PSEUDOVECTORP): Use it.
11661 * fns.c (internal_equal): Adapt code to extract pvectype.
11662 * emacs.c (gdb_pvec_type): Update type.
11663 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11664 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11665 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11666 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11667 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11668 abusing vector->header.next.nbytes.
11669 (live_vector_p): Use PVEC_TYPE.
11670 (mark_object): Adapt code to extract pvectype. Use switch.
11672 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11674 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11675 Tighten new eassert a bit.
11677 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11679 Fix compilation with --enable-gcc-warnings and -O1
11680 optimization level.
11681 * doprnt.c (doprnt): Change type of tem to int, initialize
11682 to avoid compiler warning. Add eassert.
11683 * search.c (simple_search): Initialize match_byte to avoid
11684 compiler warning. Add eassert.
11686 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11688 Avoid weird behavior with large horizontal scrolls.
11689 Without this change, for example, large hscroll values would
11690 mess up Emacs's display on Fedora 15 x86, presumably due to
11691 overflows in int calculations in the display code.
11692 Also, if buffers had long lines, Emacs would freeze.
11693 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11694 (set_window_hscroll): New function, containing the old guts of
11695 Fset_window_hscroll. Return the clipped value.
11696 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11697 This avoids the need to check against PTRDIFF_MAX.
11699 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11701 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11703 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11705 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11707 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11708 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11709 since GCC 4.4.6 issues a bogus warning for them.
11711 Fix bugs in file timestamp newness comparisons.
11712 * fileio.c (Ffile_newer_than_file_p):
11713 * lread.c (Fload): Use full timestamp resolution of files,
11714 not just the 1-second resolution, so that files that are only
11715 slightly newer still count as newer.
11716 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11717 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11719 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11721 * fileio.c: Improve handling of file time marker. (Bug#11852)
11722 (special_mtime): New function.
11723 (Finsert_file_contents, Fverify_visited_file_modtime):
11724 Use it to set special mtime values consistently.
11726 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11728 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11729 marker for non-existing file. (Bug#11852)
11731 2012-07-03 Glenn Morris <rgm@gnu.org>
11733 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11734 and did not make it into globals.h).
11736 2012-07-03 Tom Tromey <tromey@redhat.com>
11738 * window.c (Fset_window_margins, Fset_window_fringes)
11739 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11740 * textprop.c (Fprevious_property_change): No longer static.
11741 * syntax.c (Fsyntax_table_p): No longer static.
11742 * process.c (Fget_process, Fprocess_datagram_address): No longer
11744 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
11745 * keyboard.c (Fcommand_execute): No longer static.

11764 * fontset.h: Remove EXFUN.
11765 * font.h: Remove EXFUNs.
11766 * dosfns.c (system_process_attributes): Remove EXFUN.
11767 * keymap.h: Remove EXFUNs.
11768 * lisp.h: Remove EXFUNs.
11769 * w32term.h: Remove EXFUNs.
11770 * window.h: Remove EXFUNs.
11771 * xsettings.h: Remove EXFUN.
11772 * xterm.h: Remove EXFUN.
11774 2012-07-03 Glenn Morris <rgm@gnu.org>
11776 * lisp.h (Frandom): Make it visible to C.
11777 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11778 buffer for invisible buffers. (Bug#1229)
11780 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11782 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11783 values which aren't power of 2.
11784 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11785 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11788 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11790 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11792 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11794 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11796 * alloc.c (allocate_vector_block): Remove redundant
11797 calls to mallopt if DOUG_LEA_MALLOC is defined.
11798 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11799 avoid calls to mallopt if zero_vector is returned.
11801 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11803 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11804 is enabled, avoid dereferencing NULL current_sblock if
11807 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11809 Cleanup basic buffer management.
11810 * buffer.h (struct buffer): Change layout to use generic vector
11811 marking code. Fix some comments. Change type of 'clip_changed'
11812 to bitfield. Remove unused #ifndef old.
11813 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11814 (GET_OVERLAYS_AT): Fix indentation.
11815 (for_each_per_buffer_object_at): New macro.
11816 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11817 (Fbuffer_local_variables): Use it.
11818 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11819 * alloc.c (allocate_buffer): Adjust to match new layout of
11820 struct buffer. Fix comment.
11821 (mark_overlay): New function.
11822 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11823 Lisp area of struct buffer.
11824 (mark_object): Use it. Adjust marking of misc objects
11825 and related comments.
11827 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11829 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11830 wrapper that is not needed because the wrapped code is a no-op (zero
11831 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11832 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11834 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11836 * alloc.c (mark_buffer): Simplify. Remove prototype.
11837 (mark_object): Add comment. Reorganize marking of vector-like
11838 objects. Use CHECK_LIVE for all vector-like objects except buffers
11839 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11840 Avoid redundant calls to mark_vectorlike for bool vectors.
11842 2012-06-30 Glenn Morris <rgm@gnu.org>
11844 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11846 * epaths.in (PATH_SITELOADSEARCH): New.
11847 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11848 This is rather than relying on --enable-locallisppath elements
11849 having "site-lisp" in their names. (Bug#10208#25, 11658)
11851 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11853 * w32proc.c (sys_select): Accept and ignore one more argument.
11855 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11857 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11858 (pselect) [!MS_DOS]: Redirect to sys_select.
11860 * sysdep.c: Don't include dos.h and dosfns.h.
11862 * process.c (sys_select):
11863 * msdos.c (sys_select): Accept one more argument and ignore it.
11865 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11866 adapt data types and code to that.
11869 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11870 which clashes with the gnulib function of the same name.
11872 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11874 * font.c (font_style_to_value, font_style_symbolic)
11875 (font_prop_validate_style): Add type checks for values in
11878 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11880 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11883 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11885 * xdisp.c (try_window_id): Undo last change.
11887 * w32.c (getwd): Adjust commentary about startup_dir.
11888 (init_environment): Always call sys_access, even in non-MSVC
11889 builds. Don't chdir to the directory of the Emacs executable.
11890 This undoes code from 1997 which was justified by the need to
11891 "avoid conflicts when removing and renaming directories". But its
11892 downside was that every relative file name was being interpreted
11893 relative to the directory of the Emacs executable, which can never
11894 be TRT. In particular, it broke sys_access when called with
11895 relative file names.
11896 (sys_access): Map GetLastError to errno.
11898 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11900 * window.h (struct window): Change type of 'fringes_outside_margins'
11901 to bitfield. Fix comment. Adjust users accordingly.
11902 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11904 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11907 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11909 * gnutls.c (emacs_gnutls_handshake):
11910 Add QUIT to make the loop interruptible.
11912 2012-06-29 Glenn Morris <rgm@gnu.org>
11914 * charset.c (init_charset): Make lack of etc/charsets fatal.
11916 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11918 * editfns.c (region_limit): Fix type mismatch.
11920 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11922 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11923 undefined. Convert from xassert to eassert.
11924 * nsmenu.m: Convert from xassert to eassert.
11925 * nsterm.m: Likewise.
11927 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11931 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11933 Avoid integer overflow on scroll-left and scroll-right.
11934 * window.c (HSCROLL_MAX): New macro.
11935 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11936 overflow when requested scroll falls outside ptrdiff_t range.
11938 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11940 * window.h (struct window): Change type of 'hscroll',
11941 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11942 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11943 Adjust users accordingly.
11944 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11945 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11946 from EMACS_INT to ptrdiff_t.
11947 (make_window): Omit redundant initialization.

11965 enabled with --enable-checking=[all,glyphs] configure option.
11966 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11967 adjust comments accordingly.

11969 undefined, adjust comments accordingly.

12016 * alloc.c (allocate_string_data): Remove dead code.
12017 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

12022 * alloc.c (allocate_string): Omit intervals initialization.

12080 * alloc.c: Remove build_string.

12088 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12090 Use sprintf return value instead of invoking strlen on result.
12091 In the old days this wasn't portable, since some sprintf
12092 implementations returned char *. But they died out years ago and
12093 Emacs already assumes sprintf returns int.
12094 Similarly for float_to_string.
12095 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
12096 * ccl.c (ccl_driver):
12097 * character.c (string_escape_byte8):

12100 * print.c (print_object):
12101 * xdisp.c (message_dolog):
12102 * xfns.c (syms_of_xfns):
12103 Use sprintf or float_to_string result to avoid need to call strlen.
12104 * data.c (Fnumber_to_string):
12105 Use make_unibyte_string, since the string must be ASCII.
12106 * lisp.h, print.c (float_to_string): Now returns int length.
12107 * term.c (produce_glyphless_glyph):
12108 Use sprintf result rather than recomputing it.
12110 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12111 * Makefile.in (ALL_CFLAGS):
12112 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

12117 * dispextern.h (xstrcasecmp): Define to library function
12118 strcasecmp if available.

12137 sprintf already null-terminates its output.
12139 * xfns.c (x_window): Remove redundant cast.
12141 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12143 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12144 `const char *' to `char *' to avoid compiler warning.
12146 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12148 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12149 instead of truncating it to 63 (admittedly a generous limit).
12151 * process.c: Fix spelling and caps in comments.
12153 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12155 * emacs.c (setpgrp): Remove definition, unused.

12165 (SYSTIME_H): Add nt/inc/sys/time.h.
12167 * systime.h [WINDOWSNT]: Include sys/time.h.
12169 * s/ms-w32.h (struct timespec): Definition moved from
12170 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
12172 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12174 Switch from NO_RETURN to C11's _Noreturn (Bug#11750).

12206 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
12207 * lisp.h (WAIT_READING_MAX): New macro.
12208 * dispnew.c (Fsleep_for, sit_for):
12209 * keyboard.c (kbd_buffer_get_event):
12210 * process.c (Faccept_process_output):
12211 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12212 This improves on the previous patch, which introduced a bug
12213 when time_t is unsigned and as wide as intmax_t.
12214 See <http://bugs.gnu.org/9000#51>.
12216 2012-06-23 Eli Zaretskii <eliz@gnu.org>

12245 language ID in the event parameters.
12247 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12248 event.code, not the obscure "character set ID".

12279 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12281 Support higher-resolution time stamps (Bug#9000).
12282 The time stamps are only nanosecond-resolution at the C level,
12283 since that's the best that any real-world system supports now.
12284 But they are picosecond-resolution at the Lisp level, as that's
12285 easy, and leaves room for future OS improvements.
12287 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12290 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12291 Don't get current time unless it's needed.
12293 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12294 now provides it if it's absent.
12295 (start_atimer): Port to higher-res time stamps.
12296 Check for time stamp overflow. Don't get current time more
12297 often than is needed.
12299 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12300 Include systime.h, not time.h.
12301 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12303 * dired.c: Include stat-time.h.
12304 (Ffile-attributes): File times now have higher resolution.
12306 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12307 (struct image): Timestamp now has higher resolution.
12309 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12310 has at least microseconds now. All uses removed.
12311 (update_frame, update_single_window, update_window, update_frame_1)
12312 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12313 (duration_to_sec_usec): Remove; no longer needed.
12315 * editfns.c (time_overflow): Now extern.
12316 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12317 (float-time, Fformat_time_string, Fcurrent_time_string)

12321 (decode_time_components, lisp_seconds_argument): New functions.
12322 (make_time): Now static.
12323 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12324 Report an error if the time is invalid, rather than having the caller
12327 * fileio.c: Include <stat-time.h>
12328 (Fcopy_file): Copy higher-resolution time stamps.
12329 Prefer to set the time stamp via a file descriptor if that works.
12330 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12331 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12332 (Fvisited_file_modtime, Fset_visited_file_modtime):
12333 Support higher-resolution time stamps.
12335 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12337 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12339 * image.c (prepare_image_for_display, clear_image_cache)
12340 (lookup_image): Port to higer-resolution time stamps.
12342 * keyboard.c (start_polling, bind_polling_period):
12343 Check for time stamp overflow.
12344 (read_char, kbd_buffer_get_event, timer_start_idle)
12345 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12346 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12347 Port to higher-resolution time stamps. Do not assume time_t is signed.
12348 (decode_timer): New function. Timers are now vectors of length 9,
12349 not 8, to accommodate the picosecond component.
12350 (timer_check_2): Use it.
12352 * nsterm.m (select_timeout, timeval_subtract): Remove.
12353 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12354 as they're a bit more accurate and handle overflow better.
12355 (ns_select): Change prototype to be compatible with pselect.
12356 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12357 * nsterm.h (ns_select): Adjust prototype.
12359 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12360 us-resolution time stamps.
12361 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12363 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12365 * lisp.h (time_overflow): New decl.
12366 (wait_reading_process_output): First arg is now intmax_t, not int,
12367 to accommodate larger waits.
12369 * process.h (struct Lisp_Process.read_output_delay):
12370 Now counts nanoseconds, not microseconds.
12371 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12373 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12374 (wait_reading_process_output):
12375 Port to ns-resolution time stamps.
12376 (Faccept_process_output, wait_reading_process_output):
12377 Check for time stamp overflow. Do not assume time_t is signed.
12378 (select_wrapper): Remove; we now use pselect.
12379 (Fprocess_attributes): Now generates ns-resolution time stamps.
12381 * sysdep.c: Include utimens.h. Don't include utime.h
12382 or worry about struct utimbuf; gnulib does that for us now.
12383 (gettimeofday): Remove; gnulib provides a substitute.
12384 (make_timeval): New function.
12385 (set_file_times): Now sets ns-resolution time stamps.
12386 New arg FD; all uses changed.
12387 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12388 (system_process_attributes):
12389 Now returns ns-resolution time stamp. All uses changed.
12390 Check for time stamp overflow.
12392 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12393 provides a substitute now.
12395 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12396 since it guarantees struct timespec.
12397 (EMACS_TIME): Now struct timespec, so that we can support
12398 ns-resolution time stamps.
12399 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12400 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12401 (EMACS_USECS): Remove.
12402 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12403 so multiply the arg by 1000 before storing it.
12404 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12406 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12407 Port to ns-resolution time stamps.
12408 (EMACS_TIME_NEG_P): Remove; replaced by....
12409 (EMACS_TIME_SIGN): New macro.

12411 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12412 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12413 (make_timeval, make_lisp_time, decode_time_components): New decls.
12414 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12415 that it mishandled time_t overflow. You can't compare by subtracting!
12416 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12417 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12419 * term.c: Include <sys/time.h>.
12420 (timeval_to_Time): New function, for proper overflow wraparound.
12421 (term_mouse_position, term_mouse_click): Use it.
12423 * undo.c (record_first_change): Support higher-resolution time stamps
12424 in the undo buffer.
12425 (Fprimitive_undo): Use them when restoring time stamps.
12427 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12428 (w32_get_internal_run_time):
12429 Port to higher-resolution Emacs time stamps.
12430 (ltime): Now accepts single 64-bit integer, as that's more convenient
12433 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12435 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12436 for compatibility with pselect. Support ns-resolution time stamps.
12438 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12440 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12441 Check for time stamp overflow, and support ns-resolution time stamps.
12443 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12444 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12445 (timeval_subtract): Remove; no longer needed.
12446 (XTflash, XTring_bell, x_wait_for_event):
12447 Port to ns-resolution time stamps. Don't assume time_t is signed.
12449 2012-06-22 Chong Yidong <cyd@gnu.org>

12453 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12455 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12456 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12457 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12458 staticidx goes up to 1597 out of 1600 = 0x640.)
12460 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12462 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12463 Otherwise, the umask might be mistakenly 0 while handling input signals.
12465 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
12467 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

12474 access to `contents' member of Lisp_Vector objects with AREF and ASET
12477 2012-06-19 Chong Yidong <cyd@gnu.org>
12479 * frame.c (delete_frame): When selecting a frame on a different
12480 text terminal, do not alter the terminal's top-frame.
12482 * xdisp.c (format_mode_line_unwind_data): Record the target
12483 frame's selected window and its terminal's top-frame.
12484 (unwind_format_mode_line): Restore them.
12485 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12487 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12488 since tty frames can be explicitly named.
12489 (prepare_menu_bars): Likewise.
12491 * term.c (Ftty_top_frame): New function.
12493 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12496 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12497 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12498 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12499 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
12500 (METER_1, METER_2): Simplify.
12502 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

12506 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12508 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12509 gets killed during executing of this function (Bug#11665).
12510 Try to always return Qt when the buffer has been actually killed.
12511 (Vkill_buffer_query_functions): In doc-string say that functions
12512 run by this hook should not change the current buffer.
12514 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12516 Fix recently-introduced process.c problems found by static checking.
12517 * process.c (write_queue_push, write_queue_pop, send_process):
12518 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12519 (write_queue_pop): Fix pointer signedness problem.
12520 (send_process): Remove unused local.
12522 2012-06-17 Chong Yidong <cyd@gnu.org>

12534 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
12536 * lisp.h (eassert): Assume C89 or later.
12537 This removes the need for CHECK.
12538 (CHECK): Remove. Its comments about always evaluating its
12539 argument were confusing, as 'eassert' typically does not evaluate
12542 * coding.c (produce_chars): Use ptrdiff_t, not int.
12544 * xterm.c (x_draw_underwave): Check for integer overflow.
12545 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12549 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
12550 referenced (Bug#11583).

12732 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12733 Use an inline function on all platforms when using the union type,
12734 since this is simpler and 'static inline' can be used portably

12841 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).

12879 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12880 would mishandle a string argument "Xc" if X was a multibyte
12881 character of length 2: it would truncate after X's first byte
12882 rather than including all of X.
12884 2012-06-06 Chong Yidong <cyd@gnu.org>

12933 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12935 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12936 Convert pctcpu and pctmem to Lisp float properly.
12937 Let the compiler fold better, as 100.0/0x8000 is exact.

12941 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

12953 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12954 change its type from Lisp_Object to bitfield.

12963 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12964 Use 'float' consistently, rather than 'float' in most places
12965 and 'double' in a couple of places.
12967 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12969 * xdisp.c (handle_stop): Detect whether we have overlay strings
12970 loaded by testing it->current.overlay_string_index to be
12971 non-negative, instead of checking whether n_overlay_strings is
12972 positive. (Bug#11587)

12976 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12982 * search.c (search_buffer): Remove calls to
12983 r_alloc_inhibit_buffer_relocation, as it is now called by

12989 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12990 for the duration of call to load_charset, to avoid problems with
12991 callers of maybe_unify_char that access buffer text through C
12994 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12995 decrement the inhibition flag, instead of just setting or
12998 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13000 Remove obsolete '#define static' cruft.
13001 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

13051 Bug#9642, but explicitly check that the buffer the overlay would
13052 be moved to is live and rearrange lines to make sure that errors
13053 will not put the overlay in an inconsistent state.
13054 (Fdelete_overlay): Cosmetics.

13072 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13073 This avoids undefined behavior that might cause the eassert
13074 to not catch an out-of-range value.
13076 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13078 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13079 Update dependencies.
13081 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13083 * bidi.c (bidi_mirror_char): Fix last change.
13085 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

13088 when referring to sectname field in printf format.
13090 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13092 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13093 Only r_alloc_inhibit_buffer_relocation needed to be added;
13094 the others were already declared.
13096 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13097 before checking whether it's out of range. Put the check inside
13099 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13101 2012-05-27 Ken Brown <kbrown@cornell.edu>
13103 * callproc.c (Fcall_process): Restore a line that was accidentally
13104 commented out in the 2011-02-13 change (bug#11547).
13106 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13108 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13109 defined on ralloc.c.
13111 * buffer.c [REL_ALLOC]: Remove prototypes of
13112 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13113 they are now on lisp.h.
13115 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13117 * search.c (search_buffer): Use it to inhibit relocation of buffer
13118 text while re_search_2 is doing its job, because re_search_2 is
13119 passed C pointers to buffer text. (Bug#11519)
13121 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13122 Update value to 24.
13124 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13125 state after an additional call to move_it_in_display_line_to, keep
13126 the values of it->max_ascent and it->max_descent found for the
13128 (pos_visible_p): Revert the comparison against bottom_y to what it
13129 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13132 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13134 Fix coding-related core dumps with gcc -ftrapv.
13135 The code was computing A - B, where A and B are pointers, and B is
13136 random garbage. This can lead to core dumps on platforms that
13137 have special pointer registers, and it also leads to core dumps on
13138 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13139 A - B only when B is initialized properly.
13140 * coding.c (coding_set_source, coding_set_destination): Return void.
13141 (coding_change_source, coding_change_destinations): New functions,
13142 with the old behaviors of coding_set_source and coding_set_destination.
13143 All callers that need an offset changed to use these new functions.
13145 2012-05-26 Glenn Morris <rgm@gnu.org>
13147 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13149 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13151 Extend mouse support on W32 text-mode console.
13152 * xdisp.c (draw_row_with_mouse_face):
13153 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13155 * w32console.c: Include window.h.
13156 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13158 (initialize_w32_display): Initialize mouse-highlight data.
13160 * w32inevt.c: Include termchar.h and window.h.
13161 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13162 moves, call note_mouse_highlight. If help_echo changed, call
13163 gen_help_event to produce help-echo message in the echo area.
13164 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13167 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13169 * lread.c (read1): Simplify slightly to avoid an overflow warning
13170 with GCC 4.7.0 on x86-64.
13172 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13174 * bidi.c (bidi_mirror_char): Revert last change: an int is
13175 definitely wide enough here.
13177 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13179 Fix integer width and related bugs (Bug#9874).

13189 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13190 (allocate_pseudovector):
13191 Use int, not EMACS_INT, where int is wide enough.
13192 (inhibit_garbage_collection, Fgarbage_collect):
13193 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13194 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13195 int might not be wide enough.
13196 (bidi_cache_search, bidi_cache_find, bidi_init_it)

13211 (Foverlay_recenter, last_overlay_modification_hooks_used)
13212 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13213 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13214 (validate_region): Omit unnecessary test for b <= e,
13215 since that's guaranteed by the previous test.
13216 (adjust_overlays_for_delete): Avoid pos + length overflow.
13217 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13218 (report_overlay_modification):
13219 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13220 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13221 Omit pointer cast, which isn't needed anyway, and doesn't work
13222 after the EMACS_INT -> ptrdiff_t change.
13223 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13224 * buffer.h: Adjust decls to match defn changes elsewhere.
13225 (struct buffer_text, struct buffer):
13226 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13227 Use EMACS_INT, not int, where int might not be wide enough.
13228 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13229 not int, to avoid needless 32-bit limit on 64-bit hosts.
13230 (exec_byte_code): Use tighter memory-full test, one that checks
13231 for alloca overflow. Don't compute the address of the object just
13232 before an array, as that's not portable. Use EMACS_INT, not
13233 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13234 * callint.c (Fcall_interactively):
13235 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13236 * callproc.c (call_process_kill, Fcall_process):
13237 Don't assume pid_t fits into an Emacs fixnum.
13238 (call_process_cleanup, Fcall_process, child_setup):

13246 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13247 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13248 (casify_object): Avoid integer overflow when overallocating buffer.
13249 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13250 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13251 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13252 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13253 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13254 integers are now checked earlier. All uses replaced with XINT.
13256 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13257 For CCL_MapSingle, check that content and value are in int range.
13258 (ccl_driver, Fregister_code_conversion_map):
13259 Check that Vcode_version_map_vector is a vector.
13260 (resolve_symbol_ccl_program): Check that vector header is in range.
13261 Always copy the vector, so that we can check its contents reliably
13262 now rather than having to recheck each instruction as it's being
13263 executed. Check that vector words fit in 'int'.
13264 (ccl_get_compiled_code, Fregister_ccl_program)
13265 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13266 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13267 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13268 contents are in range.
13269 (Fccl_execute_on_string): Check that status is in range.
13270 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13271 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13272 Accept and return EMACS_INT, not int, because callers can pass values
13273 out of 'int' range.

13275 (multibyte_chars_in_text, parse_str_as_multibyte)

13279 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13280 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13281 avoid mishandling large integers.
13282 * character.h: Adjust decls to match defn changes elsewhere.
13283 * charset.c (load_charset_map_from_file, find_charsets_in_text)

13288 Don't assume fixnum fits in int.
13289 (load_charset_map_from_vector, Fmap_charset_chars):
13290 Remove now-unnecessary CHECK_NATNUMs.
13291 (Fdefine_charset_internal): Check ranges here, more carefully.
13292 Don't rely on undefined behavior with signed left shift overflow.
13293 Don't assume unsigned int fits into fixnum, or that fixnum fits
13294 into unsigned int. Don't require max_code to be a valid fixnum;
13295 that's not true for gb10830 4-byte on a 32-bit host. Allow
13296 invalid_code to be a cons, for the same reason. Require code_offset
13297 to be a character. Avoid int overflow if max_char is close
13299 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13300 this is intended anyway and avoids some undefined behavior.
13301 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13302 INDEX_TO_CODE_POINT, as that's what it expects.
13303 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13304 * charset.h (DECODE_CHAR): Return int, not unsigned;
13305 this is what was intended anyway, and it avoids undefined behavior.
13306 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13307 integer-overflow issues.
13308 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13309 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13310 where the argument is EMACS_INT, and this behavior is not intended.
13311 * chartab.c (Fmake_char_table, Fset_char_table_range)
13312 (uniprop_get_decoder, uniprop_get_encoder):
13313 Don't assume fixnum fits in int.
13314 * cmds.c (move_point): New function, that does the gist of
13315 Fforward_char and Fbackward_char, but does so while checking
13316 for integer overflow more accurately.
13317 (Fforward_char, Fbackward_char): Use it.
13318 (Fforward_line, Fend_of_line, internal_self_insert)
13319 (internal_self_insert):
13320 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13380 Do not attempt to compute the address of the object just before a

14138 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14139 and right-margin display specs even if the spec is invalid or we
14140 are on a TTY, and thus unable to display on the fringes.
14141 That's because the text with the property will not be displayed anyway,
14142 so we need to signal to the caller that this is a "replacing"
14143 display spec. This fixes display when the spec is invalid or we
14146 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14148 * unexaix.c (make_hdr): Fix typo in prototype.
14149 This bug broke the build on AIX. Problem reported by Gilles Pion.
14151 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14153 * keyboard.c (kbd_buffer_get_event): Read special events also in
14154 batch mode. (Bug#11415)
14156 2012-05-12 Glenn Morris <rgm@gnu.org>
14158 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14160 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14162 * lisp.mk (lisp): Add newcomment.elc.
14164 2012-05-12 Glenn Morris <rgm@gnu.org>
14166 * Makefile.in (MKDIR_P): New, set by configure.
14167 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14169 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14171 Remove unused function hourglass_started.
14172 * dispextern.h (hourglass_started):
14173 * w32fns.c (hourglass_started):
14174 * xdisp.c (hourglass_started): Remove.
14176 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14178 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14179 Update dependencies.
14181 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14183 * xgselect.c (xg_select): Put maxfds+1 into a var.
14184 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14186 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14188 2012-05-10 Dave Abrahams <dave@boostpro.com>
14190 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14191 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14193 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14195 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14196 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14197 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14198 Initialize xd_registered_buses.
14200 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14202 Untag more efficiently if USE_LSB_TAG.
14203 This is based on a proposal by YAMAMOTO Mitsuharu in
14204 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14205 For an admittedly artificial (nth 8000 longlist) benchmark on
14206 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14207 Emacs's overall text size by 1%.
14208 * lisp.h (XUNTAG): New macro.
14209 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14210 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14211 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14212 * eval.c (Fautoload):
14213 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14214 * frame.h (XFRAME): Use XUNTAG.
14216 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14217 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14218 Remove unportable assumptions about print widths of types like
14220 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14221 intptr_t when converting between pointer and integer, to avoid GCC
14222 warnings about wrong width.
14224 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14226 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14227 stack for each reader_thread, instead of defaulting to 8MB
14228 determined by the linker. This avoids failures in creating
14229 subprocesses on Windows 7, see the discussion in this thread:
14230 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14232 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14234 Fix up display of the *Minibuf-0* buffer in the mini window.
14235 * keyboard.c (read_char): Don't clear the echo area if there's no
14237 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14238 contents of *Minibuf-0*) if there's no message displayed in its stead.
14240 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14242 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14245 2012-05-06 Chong Yidong <cyd@gnu.org>
14247 * lisp.mk (lisp): Update.
14249 2012-05-05 Jim Meyering <meyering@redhat.com>
14251 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14253 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14255 * data.c (PUT_ERROR): New macro.
14256 (syms_of_data): Use it. Add new error type `user-error'.
14257 * undo.c (user_error): New function.
14258 (Fprimitive_undo): Use it.
14259 * print.c (print_error_message): Adjust print style for `user-error'.
14260 * keyboard.c (user_error): New function.
14261 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14263 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14265 Do not limit current-time-string to years 1000..9999.
14266 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14267 (Fcurrent_time_string): Support any year that is supported by the
14268 underlying localtime representation. Don't use asctime, as it
14269 has undefined behavior for years outside the range -999..9999.
14271 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14273 Fix race conditions involving setenv, gmtime, localtime, asctime.
14274 Without this fix, interrupts could mess up code that uses these
14275 nonreentrant functions, since setting TZ invalidates existing
14276 tm_zone or tzname values, and since most of these functions return
14277 pointers to static storage.
14278 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14279 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14280 Grow the critical sections to include not just invoking
14281 localtime/gmtime, but also accessing these functions' results
14282 including their tm_zone values if any, and any related TZ setting.
14283 (format_time_string): Last arg is now struct tm *, not struct tm **,
14284 so that the struct tm is saved in the critical section.
14285 All callers changed. Simplify allocation of initial buffer, partly
14286 motivated by the fact that memory allocation needs to be outside
14287 the critical section.
14289 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14291 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14292 with RESET_INTERVAL.
14294 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14295 Remove duplicated buffer name initialization.
14297 2012-05-02 Jim Meyering <jim@meyering.net>
14299 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14301 * xfns.c (x_window): Use xstrdup (Bug#11375).
14303 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14305 * xdisp.c (pos_visible_p): If already at a newline from the
14306 display string before the 'while' loop, don't walk back the glyphs
14307 from it3.glyph_row. Solves assertion violation when the display
14308 string begins with a newline (egg.el). (Bug#11367)
14310 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14312 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14315 2012-05-01 Glenn Morris <rgm@gnu.org>
14317 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14318 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14319 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14320 All were removed before 23.1.
14322 * dispnew.c: Remove HAVE_LIBNCURSES test;
14323 it is always true on relevant platforms.
14325 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14326 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14328 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14330 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14332 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14333 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14336 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14338 Do not avoid creating empty evaporating overlays (Bug#9642).
14339 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14340 That is, do not delete an evaporating overlay if it becomes
14341 empty after its bounds are adjusted to fit within its buffer.
14342 This fix caused other problems, and I'm reverting it until we get
14343 to the bottom of them.
14345 2012-04-27 Chong Yidong <cyd@gnu.org>
14347 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14349 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14351 * xdisp.c (pos_visible_p): If the window start position is beyond
14352 ZV, start the display from buffer beginning. Prevents assertion
14353 violation in init_iterator when the minibuffer window is scrolled
14354 via the scroll bar.
14356 * window.c (window_scroll_pixel_based): Likewise.
14358 2012-04-27 Chong Yidong <cyd@gnu.org>
14360 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14362 2012-04-27 Glenn Morris <rgm@gnu.org>
14364 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14365 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14367 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14369 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14370 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14372 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14374 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14375 display element, check also the underlying string or buffer
14376 character. (Bug#11341)
14378 * w32menu.c: Include w32heap.h.
14379 (add_menu_item): If the call to AppendMenuW (via
14380 unicode_append_menu) fails, disable Unicode menus only if we are
14381 running on Windows 9X/Me.
14383 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14385 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14386 (xgetint): Add missing shift for LSB tags.
14388 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14390 * keyboard.c (read_char): Don't wipe echo area for select window
14391 events: These might get delayed via `mouse-autoselect-window'
14394 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14396 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14397 manipulation of :loaded-from data.
14399 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14401 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14402 now a cons (bug#11311).
14404 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14406 Do not create empty overlays with the evaporate property (Bug#9642).
14407 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14408 if it becomes empty after its bounds are adjusted to fit within
14409 its buffer. Without this fix, in a nonempty buffer (let ((o
14410 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14411 yields an empty overlay that has the evaporate property, which is
14412 not supposed to happen.
14414 Fix minor GTK3 problems found by static checking.
14415 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14416 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14417 (struct _EmacsFixedClass, emacs_fixed_get_type):
14418 Move decls here from emacsgtkfixed.h, since they needn't be public.
14419 (emacs_fixed_get_type): Now static.
14420 (emacs_fixed_class_init): Omit unused local.
14421 (emacs_fixed_child_type): Remove; unused.

14423 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14424 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14425 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14426 (EMACS_FIXED_GET_CLASS): Remove; unused.
14427 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14429 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14430 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14432 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14434 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14435 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14436 (__malloc_size_t, __malloc_ptrdiff_t):
14437 Remove. All uses removed, replaced by the definiens if needed,
14438 since we can assume C89 or better now.
14439 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

14447 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14448 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14449 Define using prototypes, not old style.
14450 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14451 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14452 (align): Don't assume that signed integer overflow wraps around.
14453 Omit unused local var.
14454 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

14456 Omit no-longer-needed casts.
14457 (valloc): Use getpagesize, not __getpagesize.
14458 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14459 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14461 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14463 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14465 Move functions from C to Lisp. Make non-blocking method calls
14466 the default. Implement further D-Bus standard interfaces.

14510 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
14511 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
14512 Do not assume ptrdiff_t is the same width as 'int'.
14514 * alloc.c: Handle unusual debugging option combinations.
14515 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14516 since the two debugging options are incompatible.
14517 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14519 (mem_init, mem_insert, mem_insert_fixup):
14520 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

14529 * sysdep.c [__FreeBSD__]: Minor cleanups.
14530 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14531 Use Emacs indenting style more consistently. Avoid some casts.
14532 Use 'double' consistently rather than mixing 'float' and 'double'.
14534 2012-04-21 Eduard Wiebe <usenet@pusto.de>
14536 * sysdep.c (list_system_processes, system_process_attributes):

14550 * print.c (print_preprocess): Only check print_depth if print-circle
14552 (print_object): Check for cycles even when print-circle is nil and

14568 * xdisp.c (string_buffer_position_lim): Limit starting position to
14570 (set_cursor_from_row): If called for a mode-line or header-line
14571 row, return zero immediately.
14572 (try_cursor_movement): If inside continuation line, don't back up
14573 farther than the first row after the header line, if any.
14574 Don't consider the header-line row as "partially visible", even if
14575 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14577 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14586 * Makefile.in (C_WARNINGS_SWITCH): Remove.
14587 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
14588 (ALL_CFLAGS): Use new macros rather than old.
14589 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
14590 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
14591 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
14592 -Wunused-result, -Wunused-variable. This should go away once
14593 the Emacs and Gnulib regex code is merged.
14594 (xmalloc, xrealloc): Now static.
14596 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

14613 New extern decls, to avoid calling undeclared functions.
14614 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14615 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14616 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14617 (NEED_MEM_INSERT): New macro.
14618 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14619 Remove one incorrect comment and fix another.
14621 Fix minor ralloc.c problems found by static checking.
14622 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

14625 (r_alloc_sbrk): Now static.
14627 Improve ralloc.c interface checking.
14628 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14629 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
14630 (r_alloc_free) [REL_ALLOC]: Move decls from here ...

14633 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14634 Remove decls. This fixes an "It stinks!".
14636 * alloc.c (which_symbols): Fix alignment issue / type clash.
14638 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14640 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14641 (struct Lisp_Misc_Any): Likewise.
14642 (struct Lisp_Free): Likewise.
14643 * alloc.c (union aligned_Lisp_Symbol): Define.

14651 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
14653 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14654 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14655 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14656 * s/netbsd.h, s/sol2-6.h:
14657 Remove definition of GC_MARK_STACK, since the default now works.
14658 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14659 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14660 no longer the default.
14661 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14663 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14665 * lread.c (lisp_file_lexically_bound_p):
14666 Fix hang at ";-*-\n" (bug#11238).
14668 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14670 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14671 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
14673 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
14675 * nsterm.m (constrainFrameRect): Always constrain when there is only

14680 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
14682 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14684 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14686 2012-04-11 Daniel Colascione <dancol@dancol.org>
14688 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14689 against is gone. It's better to use vfork now so that when Cygwin
14690 gains a new, working vfork, we use it automatically (bug#10398).
14692 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14694 * window.c (save_window_save): Obey window-point-insertion-type.

14708 (handle_interrupt): Use it.
14710 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14712 * w32.c (w32_delayed_load): Record the full path of the library
14713 being loaded (bug#10424).
14715 2012-04-09 Glenn Morris <rgm@gnu.org>
14717 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14718 not just in the obarray, before snarfing them. (Bug#11036)
14720 * Makefile.in ($(leimdir)/leim-list.el):
14721 Pass EMACS rather than BUILT_EMACS.
14723 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14725 * process.c (make_process):
14726 * process.h: Add integer `gnutls_handshakes_tried' member to
14729 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
14730 Add convenience `GNUTLS_LOG2i' macro.
14732 * gnutls.c (gnutls_log_function2i): Convenience log function.
14733 (emacs_gnutls_read): Use new log functions,
14734 `gnutls_handshakes_tried' process member, and
14735 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14736 attempts per process (connection).
14738 2012-04-09 Chong Yidong <cyd@gnu.org>
14740 * eval.c (Fuser_variable_p, user_variable_p_eh)
14741 (lisp_indirect_variable): Functions deleted.
14742 (Fdefvar): Caller changed.
14744 * callint.c (Finteractive, Fcall_interactively):
14745 * minibuf.c (Fread_variable): Callers changed.
14747 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14749 * xdisp.c (set_cursor_from_row): If the display string appears in
14750 the buffer at position that is closer to point than the position
14751 after the display string, display the cursor on the first glyph of
14752 the display string. Fixes cursor display when a 'display' text
14753 property immediately follows invisible text. (Bug#11094)
14755 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14757 composite.c: use 'double' consistently
14758 * composite.c (get_composition_id): Use 'double' consistently
14759 instead of converting 'float' to 'double' and vice versa; this is
14760 easier to understand and avoids a GCC warning.
14762 2012-04-09 Glenn Morris <rgm@gnu.org>
14764 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14765 preparation for dumping it with emacs. (Bug#4789)
14766 (leimdir): New variable.
14767 ($(leimdir)/leim-list.el): New rule.
14768 (emacs$(EXEEXT)): Depend on leim-list.el.

14786 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14787 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14788 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14789 objects, as mark_maybe_pointer will catch them otherwise.
14790 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14791 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

14798 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14800 Support building on MS-Windows with libxml2.
14802 * makefile.w32-in (OBJ2): Add xml.$(O).
14803 (GLOBAL_SOURCES): Add xml.c.
14804 ($(BLD)/xml.$(O)): New dependency list.
14806 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14807 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14808 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14809 [!WINDOWSNT]: New macros.
14810 (init_libxml2_functions, libxml2_loaded_p): New functions.
14811 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14812 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14813 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14814 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14816 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14817 Call init_libxml2_functions before calling libxml2 functions.
14818 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14820 * emacs.c: Don't include libxml/parser.h.
14821 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14822 xmlCleanupParser directly.
14824 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14826 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14828 * indent.c (Fvertical_motion): If there is a display string at
14829 point, use it.vpos to compute how many lines to backtrack after
14830 move_it_to point. (Bug#11133)
14832 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14834 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14835 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14836 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14837 macros related to unification of CJK characters. For the details,
14838 see the discussion following the message here:
14839 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14841 2012-04-04 Chong Yidong <cyd@gnu.org>
14843 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14845 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14847 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14855 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14857 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14858 position we get to after a call to move_it_to fails the
14859 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14860 only if we wind up in a string from display property. (Bug#11063)
14862 * window.c (Fdelete_other_windows_internal): Invalidate the row
14863 and column information about mouse highlight, so that redisplay
14864 restores it after reallocating the glyph matrices. (Bug#7464)
14866 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14867 string comes from a `display' text property, use the buffer
14868 position of that property as if we actually saw that position in
14870 (move_it_by_lines): Remove the assertion that
14871 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14872 violated when there's a before-string at the beginning of a line.
14875 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14877 * xdisp.c (append_space_for_newline): If the default face was
14878 remapped, use the remapped face for the appended newline.
14879 (extend_face_to_end_of_line): Use the remapped default face for
14880 extending the face to the end of the line.
14881 (display_line): Call extend_face_to_end_of_line when the default
14882 face was remapped. (Bug#11068)
14884 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14886 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14888 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14890 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14892 2012-03-27 Glenn Morris <rgm@gnu.org>
14894 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14897 2012-03-26 Kenichi Handa <handa@m17n.org>

14904 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14905 (command_loop_1): Use it; inhibit selection update for
14906 handle-select-window too (Bug#8996).

14910 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14912 2012-03-25 Kenichi Handa <handa@m17n.org>
14914 * dispextern.h (struct glyph): Change the bit length of
14915 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14917 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14919 * s/ms-w32.h (tzname): Include time.h before redirecting to

14924 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14927 * xterm.c (XTread_socket): Only modify handling_signal if
14928 !SYNC_INPUT. (Bug#11080)
14930 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14932 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14933 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14934 when fetching a multibyte character consumes more bytes than
14935 CHAR_BYTES returns, due to unification of CJK characters in
14936 string_char. (Bug#11073)
14938 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14940 * process.c (wait_reading_process_output): Handle pty disconnect
14941 by refraining from sending oneself a SIGCHLD (bug#10933).
14943 2012-03-22 Chong Yidong <cyd@gnu.org>
14945 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14947 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14948 Mark string as coming from a prefix property.
14949 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14950 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14952 2012-03-21 Chong Yidong <cyd@gnu.org>
14954 * xfaces.c (Vface_remapping_alist): Doc fix.
14956 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14958 * w32proc.c (Fw32_set_console_codepage)
14959 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

14970 it fit in a valid range (Bug#11003).
14972 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14974 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14975 that is not from display property, accept the row as a "cursor
14976 row" if one of the string's character has a non-nil `cursor'
14977 property. Fixes cursor positioning when there are newlines in
14978 overlay strings, e.g. in icomplete.el. (Bug#11035)
14980 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14982 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14984 2012-03-12 Chong Yidong <cyd@gnu.org>
14986 * eval.c (inhibit_lisp_code): Rename from
14987 inhibit_window_configuration_change_hook; move from window.c.
14989 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14990 * window.c (run_window_configuration_change_hook)
14991 (syms_of_window): Callers changed.
14993 2012-03-11 Chong Yidong <cyd@gnu.org>
14995 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14997 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14999 2012-03-10 Chong Yidong <cyd@gnu.org>
15001 * frame.c (other_visible_frames): Don't assume the selected frame
15002 is visible (Bug#10955).
15004 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
15006 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
15008 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
15010 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
15011 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15014 2012-03-03 Glenn Morris <rgm@gnu.org>
15016 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15018 2012-03-02 Eli Zaretskii <eliz@gnu.org>
15020 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
15021 position past the first glyph_row that ends at ZV. (Bug#10902)
15022 (redisplay_window, next_element_from_string): Fix typos in
15024 (redisplay_window): Pass to move_it_vertically the margin in
15025 pixels, not in screen lines.
15027 2012-03-02 Glenn Morris <rgm@gnu.org>
15029 * buffer.c (buffer-list-update-hook): Doc fix.
15031 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15033 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15034 push_it before setting up the iterator for the first overlay
15035 string, even if we have an empty string loaded.

15037 stack, pop the stack. (Bug#10903)
15039 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15041 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15042 Suggested by Stefan Monnier in
15043 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15044 * alloc.c (widen_to_Lisp_Object): New static function.
15045 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15046 and widening them to Lisp_Objects. This would work even if
15047 USE_LSB_TAG is defined and wide integers are used, which might
15048 happen in a future version of Emacs.
15050 2012-02-25 Chong Yidong <cyd@gnu.org>
15052 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
15055 * xselect.c (Fx_selection_exists_p): Doc fix.
15056 (x_clipboard_manager_save_all): Print an informative message
15057 before saving to clipboard manager.
15059 2012-02-24 Chong Yidong <cyd@gnu.org>
15061 * keyboard.c (process_special_events): Handle all X selection
15062 requests in kbd_buffer, not just the next one (Bug#8869).
15064 2012-02-23 Chong Yidong <cyd@gnu.org>
15066 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15067 call when setting menu-bar-lines and tool-bar-lines parameters.
15068 (unwind_create_frame_1): New helper function.
15070 * window.c (inhibit_window_configuration_change_hook): New var.
15071 (run_window_configuration_change_hook): Obey it.
15072 (syms_of_window): Initialize it.
15074 2012-02-22 Chong Yidong <cyd@gnu.org>
15076 * xterm.c (x_draw_image_relief): Add missing type check for

15089 when computing $valmask.
15091 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15092 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15093 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15094 It's useless in that case, and it can cause problems on hosts
15095 that allocate halves of EMACS_INT values separately.
15096 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15097 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15098 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15099 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15100 it avoids undefined behavior on hosts where shifting right by more
15101 than the word width has undefined behavior.
15103 2012-02-19 Chong Yidong <cyd@gnu.org>
15105 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15106 (Funhandled_file_name_directory, Ffile_name_as_directory)
15107 (Fdirectory_file_name, Fexpand_file_name)
15108 (Fsubstitute_in_file_name): Protect against invalid file handler
15109 return values (Bug#10845).
15111 2012-02-18 Eli Zaretskii <eliz@gnu.org>

15143 2012-02-12 Chong Yidong <cyd@gnu.org>
15145 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15146 as that creates a dangerous corner case.
15148 * window.c (Fdelete_window_internal): Invalidate the mouse
15149 highlight (Bug#9904).
15151 2012-02-12 Glenn Morris <rgm@gnu.org>

15181 2012-02-07 Chong Yidong <cyd@gnu.org>
15183 * buffer.c (Fbuffer_local_variables)
15184 (buffer_lisp_local_variables): Handle unbound vars correctly;
15185 don't let Qunbound leak into Lisp.
15187 2012-02-07 Glenn Morris <rgm@gnu.org>
15189 * image.c (Fimagemagick_types): Doc fix.
15191 * image.c (imagemagick-render-type): Change it from a lisp object
15192 to an integer. Move the doc here from the lisp manual.

15209 2012-02-04 Eli Zaretskii <eliz@gnu.org>
15211 * w32.c (get_emacs_configuration_options):
15212 Include --enable-checking, if specified, in the return value.

15222 before BEGV. (Bug#10696)
15224 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15226 Handle overflow when computing char display width (Bug#9496).
15227 * character.c (char_width): Return EMACS_INT, not int.
15228 (char_width, c_string_width): Check for overflow when
15229 computing the width; this is possible now that individual

15262 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15263 first 2 arguments are identical. This makes inserting large
15264 output from a subprocess an order of magnitude faster on
15265 MS-Windows, where all sbrk'ed memory is always contiguous.

15718 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15719 verifies glyph row's hash code--we have just reallocated the

15885 is set, removing the need for VIRT_ADDRESS_VARIES.
15886 (PURE_P): Use a more-efficient implementation that needs just one

15903 behave as if the cursor position were at the window margin.
15905 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15906 and the cursor position is out of bounds, behave as if the cursor
15907 position were at the window margin. (Bug#10075)
15909 2011-11-18 Chong Yidong <cyd@gnu.org>
15911 * window.c (Fwindow_combination_limit): Make first argument

15933 compute_line_metrics.
15934 (compute_line_metrics): Call row_hash, instead of computing the
15937 * dispnew.c (verify_row_hash): Call row_hash for computing the
15938 hash code of a row, instead of duplicating code from xdisp.c.
15940 * dispextern.h (row_hash): Add prototype.
15942 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15944 * frame.c (delete_frame): Don't delete the terminal when the last

15970 (Fsplit_window_internal, saved_window)
15971 (Fset_window_configuration, save_window_save): Rename all

16440 current character, check also for next_en_type being WEAK_EN.
16441 (bidi_resolve_weak): Don't enter the expensive loop if the current
16442 position is before next_en_pos. Record the bidi type of the first
16443 non-ET, non-BN character we find, in addition to its position.
16444 (bidi_level_of_next_char): Invalidate next_en_type when
16445 next_en_pos is over-stepped.
16447 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16449 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16450 * editfns.c: Rewrite current-time-zone so that it invokes
16451 the equivalent of (format-time-string "%Z") to get the time zone name.
16452 This fixes a bug when the time zone name contains characters that
16453 need converting from the system time locale to Emacs internal format.
16454 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16455 that patch fixed format-time-string to do the conversion, but
16456 I forgot to fix current-time-zone.
16457 (format_time_string): New function, containing most of
16458 what Fformat_time_string used to contain.
16459 (Fformat_time_string): Rewrite in terms of format_time_string.
16460 This doesn't change this function's behavior.
16461 (current-time-zone): Rewrite to use format_time_string.
16462 This fixes the bug reported by Michael Schierl in
16463 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16464 Jason Rumney's 2007-06-07 change worked around this bug, but
16466 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16468 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16470 * xdisp.c (start_display): If the character at POS is displayed
16471 via a display vector, reset IT->current.dpvec_index to zero.
16472 (try_window_reusing_current_matrix): If a line ends in a display
16473 vector or the next line starts in a display vector, continue
16474 redrawing the window even though the character position of
16475 start_row was reached.
16478 2011-10-18 Chong Yidong <cyd@gnu.org>
16480 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16481 with nobreak-char-display too.
16483 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16485 Fix part 3 of bug#9771.
16486 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16487 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16488 non-neutral characters if the current character is a paragraph
16489 separator (a.k.a. Newline). This avoids running the same
16490 expensive loop twice, once when we consume the preceding newline
16491 and the other time when the line actually needs to be displayed.
16492 Avoid the loop when we see neutrals on the base embedding level
16493 following a character whose directionality is the same as the
16494 paragraph's. This avoids running the expensive loop when a line
16495 ends in a long sequence of neutrals, like control characters.
16496 Add assertion against STRONG_AL type. Slightly rearrange code
16497 that determines the type of a neutral given the first non-neutral
16499 (bidi_level_of_next_char): Set next_en_pos to zero when
16500 invalidating its info.
16502 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16504 * xdisp.c (push_display_prop): Determine whether to record string
16505 or buffer position by IT->string, not by IT->method. Allow
16506 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16507 (move_it_vertically_backward): Don't look for character position
16508 immediately after the newline when in a continuation line.
16511 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16513 * window.c (coordinates_in_window): Rewrite and delabelize
16514 vertical border check. (Bug#5357) (Bug#9618)
16516 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16518 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16519 errors in XSetWindowBorder (bug#9310).
16521 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16523 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16524 avoid crash when xmalloc overrun checking is enabled.
16526 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16528 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16529 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16530 cursor motion with <left> and <right> arrow keys.
16532 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16533 some callers set that themselves.
16535 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16537 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16538 display string and the previous row comes from the same string and
16539 is empty. (Bug#9739) (Bug#9738)
16541 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16543 * doc.c (get_doc_string): Encode file name (bug#9735).
16545 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16547 * bidi.c (bidi_level_of_next_char):
16548 * xdisp.c (get_visually_first_element): Remove old incorrect
16549 comments regarding the Unicode Line Separator character.
16551 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16553 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16555 * alloc.c (Fgc_status): Do not access beyond zombies array
16556 boundary if nzombies > MAX_ZOMBIES.
16557 * alloc.c (dump_zombies): Add missing format specifier.
16559 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16561 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16562 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16564 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16565 Some packages use them to denote characters with modifiers.
16567 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16569 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16570 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16571 matching a pp-number. Rename parameter var to var1.
16573 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16575 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16577 2011-10-08 Glenn Morris <rgm@gnu.org>
16579 * callint.c (Fcall_interactively): Give a more explicit error for the
16580 'c' case with a non-character input. (Bug#8479)
16582 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16584 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16586 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16587 lines that are hscrolled on the left.
16589 * dispnew.c (buffer_posn_from_coords): Account for a possible
16590 presence of header-line. (Bug#4426)
16592 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16594 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16595 Don't advertise functionality which we discourage or doesn't work.
16597 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16599 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16600 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16601 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16602 this makes Emacs dump core during garbage collection on rare
16603 occasions. sizeof is obviously inferior to offsetof here, so
16604 stick with offsetof.
16605 (GC_POINTER_ALIGNMENT): New macro.
16606 (mark_memory): Omit 3rd (offset) arg; caller changed.
16607 Don't assume EMACS_INT alignment is the same as pointer alignment.
16609 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16611 * keyboard.c (read_key_sequence_remapped): New var.
16612 (read_key_sequence): Compute remapping in the right buffer.
16613 (command_loop_1): Use read_key_sequence's remapping directly.
16615 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16617 * dired.c (file_name_completion): Don't expand file name.
16618 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16619 before checking file name handler.
16621 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16622 they've been requested explicitly (bug#9591).
16624 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16626 * keymap.c (Fsingle_key_description): Use make_specified_string
16627 instead of build_string to build string from push_key_description.
16630 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16632 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16633 This fixes a Y2038 bug on 64-bit hosts.
16634 * buffer.c (reset_buffer):
16635 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16636 (Fclear_buffer_auto_save_failure):
16637 Use 0, not -1, to represent an unset failure time, since time_t
16638 might not be signed.
16640 Remove dependency on glibc malloc internals.
16641 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16642 Move back here from lisp.h, but with their new implementations.
16643 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16644 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16645 * charset.c (charset_table_init): New static var.
16646 (syms_of_charset): Use it instead of xmalloc. This removes a
16647 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16648 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16649 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16650 Move back to alloc.c.
16651 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16652 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16654 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16656 * nsterm.m (windowDidResize): Call x_set_window_size only when
16657 ns_in_resize is true. Otherwise set pixelwidth/height and
16658 call change_frame_size (Bug#9628).
16660 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16662 Port --enable-checking=all to Fedora 14 x86-64.
16663 * charset.c (syms_of_charset): Also account for glibc malloc's
16664 internal overhead when calculating the initial malloc maximum.
16666 Port --enable-checking=all to Fedora 14 x86.
16667 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16669 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16670 (overrun_check_realloc, overrun_check_free):
16671 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16672 That way, xmalloc returns a properly-aligned pointer even if
16673 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16674 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16675 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16676 into account when calculating the initial malloc maximum.
16677 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16678 Move here from alloc.c, so that charset.c can use it too.
16679 Properly align; the old code wasn't right for common 32-bit hosts
16680 when configured with --enable-checking=all.
16681 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16682 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16684 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16686 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16689 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16691 * xdisp.c (compute_display_string_end): If there's no display
16692 string at CHARPOS, return -1.
16694 * bidi.c (bidi_fetch_char): When compute_display_string_end
16695 returns a negative value, treat the character as a normal
16696 character not covered by a display string. (Bug#9624)
16698 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16700 * lread.c (Fread_from_string): Fix typo in docstring.
16702 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16704 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16705 newline, reseat the iterator instead of bidi-iterating there one
16706 character at a time. (Bug#9610)
16707 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16708 TO_CHARPOS if the bidi iterator is at base embedding level.
16710 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16712 * lread.c (readevalloop): Use correct code for NBSP.
16713 (read1): Likewise. (Bug#9608)
16715 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16717 * dbusbind.c (Fdbus_register_signal): When service is not
16718 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16720 2011-09-25 Glenn Morris <rgm@gnu.org>
16722 * buffer.c (truncate-lines): Doc fix.
16724 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16726 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16727 (Fset_window_next_buffers): Doc fix.
16729 2011-09-24 Glenn Morris <rgm@gnu.org>
16731 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16733 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16735 Fix minor problems found by static checking.
16736 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16737 * indent.c (Fvertical_motion): Fix == vs = typo.
16739 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16741 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16742 Default value is now t. Doc fix.
16744 * indent.c (Fvertical_motion): Compute and apply the overshoot
16745 logic when moving up, not only when moving down. Fix the
16746 confusing name and values of the it_overshoot_expected variable;
16747 logic changes accordingly. (Bug#9254) (Bug#9549)
16749 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16750 CHARPOS is covered by a display string which includes newlines.
16751 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16752 is covered by a display string with embedded newlines.
16754 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16756 * dbusbind.c (Fdbus_register_signal): Add match rule to
16757 Vdbus_registered_objects_table. (Bug#9581)
16758 (Fdbus_register_method, Vdbus_registered_objects_table):
16761 2011-09-24 Jim Meyering <meyering@redhat.com>
16763 do not ignore write error for any output size
16764 The previous change was incomplete.
16765 While it makes emacs --batch detect the vast majority of stdout
16766 write failures, errors were still ignored whenever the output size is
16767 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16768 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16769 && echo FAIL: ignored write error
16770 FAIL: ignored write error
16771 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16772 && echo FAIL: ignored write error
16773 FAIL: ignored write error
16774 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16776 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16778 * emacs.c (Fkill_emacs): In noninteractive mode exit
16779 non-successfully if a write error occurred on stdout. (Bug#9574)
16781 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16783 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16786 * dispextern.h (struct it): Update the comment documenting what
16789 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16791 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16792 a display string, extend search for cursor position to end of row.
16793 (find_row_edges): If the row ends in a newline from a display
16794 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16795 Handle the case of a display string with multiple newlines.
16796 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16797 non-empty line. Fixes confusing cursor motion with arrow keys at
16798 the beginning of a line that starts with whitespace.
16800 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16802 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16805 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16807 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16808 boolean (Bug#9154).
16810 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16812 * xdisp.c (display_line): Record maximum and minimum buffer
16813 positions even if no glyphs were produced (e.g., by a zero-width
16814 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16815 buffer positions that will be removed from the glyph row because
16817 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16818 column is beyond frame width: don't subtract 1 "pixel" when
16819 computing width of the stretch.
16820 (reseat_at_next_visible_line_start): Undo the change made on
16821 2011-09-17 that saved paragraph information and restored it after
16822 the call to `reseat'. (Bug#9545)
16824 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16826 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16827 and turn window cursor on if cleared (Bug#9415).
16829 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16831 * search.c (boyer_moore): Take unibyte characters from pattern
16832 literally. (Bug#9458)
16834 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16836 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16838 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16840 Fix minor problem found by static checking.
16841 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16842 initialized, to pacify gcc -Wuninitialized.
16844 * fileio.c: Report proper errno when syscall falls.
16845 (Finsert_file_contents): Save and restore errno,
16846 so that report_file_error outputs the correct diagnostic.
16847 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16849 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16851 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16853 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16855 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16856 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16858 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16860 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16861 about the current paragraph and restore it after the call to reseat.
16863 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16864 (bidi_find_paragraph_start): Search back for paragraph beginning
16865 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16866 (bidi_move_to_visually_next): Only trigger paragraph-related
16867 computations when the last character is a newline or at EOB, not
16868 just any NEUTRAL_B. (Bug#9470)
16870 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16871 truncated lines if point is covered by a display string. (Bug#9524)
16873 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16875 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16876 (cons_to_x_long): New function.
16877 (lisp_data_to_selection_data): Use it. Correct the test for
16878 short-versus-long data; it was negated. Break out of vector
16879 loop, for efficiency, when a long datum is discovered.
16881 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16883 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16885 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16887 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16888 GCC PR/17406) by declaring this function with external scope.
16890 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16892 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16893 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16895 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16897 * editfns.c (Fformat): Correctly handle text properties on "%%".
16899 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16901 * xterm.c (x_draw_composite_glyph_string_foreground):
16902 * w32term.c (x_draw_composite_glyph_string_foreground):
16903 * term.c (encode_terminal_code):
16904 * composite.c (composition_update_it, get_composition_id):
16905 * xdisp.c (get_next_display_element)
16906 (fill_composite_glyph_string): Add comments about special meaning
16907 of TAB characters in a composition.
16909 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16911 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16912 This occurs when processing a multibyte format.
16913 Problem reported by Wolfgang Jenker.
16915 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16917 * xdisp.c (try_cursor_movement): Only check for exact match if
16918 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16920 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16922 Remove unused external symbols.
16923 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16924 * xdisp.c (calc_pixel_width_or_height): Now static.
16925 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16926 * indent.c (check_display_width):
16927 * w32term.c: Fix comment to match code.
16928 * xterm.c, xterm.h (x_catching_errors): Remove.
16930 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16932 * xselect.c: Use signed conversions more consistently (Bug#9498).
16933 (selection_data_to_lisp_data): Assume incoming selection data are
16934 signed integers, not unsigned. This is to be consistent with
16935 outgoing selection data, which was modified to use signed integers
16936 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16937 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16938 expects long, not unsigned long.
16940 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16942 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16943 computation of loop end. Reported by Johan Bockgård
16946 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16948 * frame.c (Fother_visible_frames_p): Function deleted.
16950 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16952 * indent.c (compute_motion): Process display vector front to back
16953 rather than the other way around. (Bug#2496)
16955 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16957 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16959 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16961 * minibuf.c (Fread_from_minibuffer): Doc fix.
16963 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16965 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16966 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16968 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16970 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16971 value for non-existent files.
16973 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16975 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16976 set its "size" to -1. This will set the modtime_size field of
16977 the corresponding buffer to -1, which is what
16978 verify-visited-file-modtime expects for files that do not exist.
16981 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16983 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16985 * lisp.h: ... from here. push_key_description is no longer
16986 defined in keyboard.c, so its declaration should not be in
16987 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16988 logically belongs with push_key_description.
16990 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16992 * buffer.h: Include <sys/types.h> instead of <time.h>.
16993 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16994 Problem reported by Herbert J. Skuhra.
16996 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16998 * xml.c (parse_region): Make the parsing work for
16999 non-comment-starting XML files again (bug#9144).
17001 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17003 * image.c (gif_load): Fix calculation of bottom and right corner.
17006 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17008 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17009 redisplay in small windows.
17011 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17013 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17015 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17017 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17018 Operate on live windows only.
17020 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17022 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17024 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17026 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17027 only under bidi iteration.
17029 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17031 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17033 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17035 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17036 Without this fix, the command to link temacs failed due to an
17037 undefined symbol __builtin_isnan. This is because
17038 /usr/include/iso/math_c99.h #defines isnan(x) to
17039 __builtin_isnan(x), but the bundled gcc, which identifies itself
17040 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17042 * floatfns.c (isnan): #undef, and then #define to a clone of
17044 (Fisnan): Always define, since it's always available now.
17045 (syms_of_floatfns): Always define isnan at the Lisp level.
17047 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17049 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17051 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17053 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17054 The previous code assumed that file offsets (off_t values) fit in
17055 EMACS_INT variables, which is not true on typical 32-bit hosts.
17056 The code messed up by falsely reporting buffer overflow in cases
17057 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17058 when "big" contains more than 2**29 bytes, even though this
17059 inserts just one byte and does not overflow the buffer.
17060 (Finsert_file_contents): Store file offsets as off_t
17061 values, not as EMACS_INT values. Check for overflow when
17062 converting between EMACS_INT and off_t. When checking for
17063 buffer overflow or for overlap, take the offsets into account.
17064 Don't use EMACS_INT for small values where int suffices.
17065 When checking for overlap, fix a typo: ZV was used where
17066 ZV_BYTE was intended.
17067 (Fwrite_region): Don't assume off_t fits into 'long'.
17068 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17070 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17072 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17074 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17076 sprintf-related integer and memory overflow issues (Bug#9412).
17078 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17079 (esprintf, exprintf, evxprintf): New functions.
17080 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17081 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17082 (modify_event_symbol): Do not assume that the length of
17083 name_alist_or_stem is safe to alloca and fits in int.
17084 (Fexecute_extended_command): Likewise for function name and binding.
17085 (Frecursion_depth): Wrap around reliably on integer overflow.
17086 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17087 since some callers pass EMACS_INT values.
17088 (Fsingle_key_description): Don't crash if symbol name contains more
17089 than MAX_ALLOCA bytes.
17090 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17091 (get_minibuffer): Arg is now EMACS_INT, not int.
17092 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17093 (esprintf, exprintf, evxprintf): New decls.
17094 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17096 * dbusbind.c (signature_cat): New function.
17097 (xd_signature, Fdbus_register_signal):
17098 Do not overrun buffer; instead, report string overflow.
17100 * dispnew.c (add_window_display_history): Don't overrun buffer.
17101 Truncate instead; this is OK since it's just a log.
17103 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17104 even if the time zone offset is outlandishly large.
17105 Don't mishandle offset == INT_MIN.
17107 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17108 when creating daemon; the previous buffer-overflow check was incorrect.
17110 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17111 which has the guts of the old verror function.
17113 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17114 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17116 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17117 (font_unparse_xlfd): Don't blindly alloca long strings.
17118 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17119 fits in int, when using sprintf. Use single snprintf to count
17120 length of string rather than counting it via multiple sprintfs;
17121 that's simpler and more reliable.
17122 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17123 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17124 sprintf, in case result does not fit in int.
17126 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17127 (fontset_from_font): Print it.
17129 * frame.c (tty_frame_count): Now printmax_t, not int.
17130 (make_terminal_frame, set_term_frame_name): Print it.
17131 (x_report_frame_params): In X, window IDs are unsigned long,
17132 not signed long, so print them as unsigned.
17133 (validate_x_resource_name): Check for implausibly long names,
17134 and don't assume name length fits in 'int'.
17135 (x_get_resource_string): Don't blindly alloca invocation name;
17136 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17139 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17140 (xg_check_special_colors, xg_set_geometry):
17141 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17143 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17144 Use esprintf, not sprintf, in case result does not fit in int.
17146 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17147 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17148 it as a large positive number.
17149 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17150 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17152 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17153 in case result does not fit in int.
17155 * print.c (float_to_string): Detect width overflow more reliably.
17156 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17157 buffer overrun. Don't assume list length fits in 'int'. Treat
17158 print length of 0 as 0, not as infinity; to be consistent with other
17159 uses of print length in this function. Don't overflow print length
17160 index. Don't assume hash table size fits in 'long', or that
17161 vectorlike size fits in 'unsigned long'.
17163 * process.c (make_process): Use printmax_t, not int, to format
17164 process-name gensyms.
17166 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17168 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17169 to avoid potential buffer overrun.
17171 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17172 if X resource line is longer than 512 bytes.
17174 * xfns.c (x_window): Make sprintf buffer a bit bigger
17175 to avoid potential buffer overrun.
17177 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17179 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17181 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17183 Integer overflow fixes for scrolling, etc.
17184 Without these, Emacs silently mishandles large integers sometimes.
17185 For example, "C-u 4294967297 M-x recenter" was treated as if
17186 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17188 * xdisp.c (try_window_id): Check Emacs fixnum range before
17189 converting to 'int'.
17191 * window.c (window_scroll_line_based, Frecenter):
17192 Check that an Emacs fixnum is in range before assigning it to 'int'.
17193 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17194 values converted from Emacs fixnums.
17195 (Frecenter): Don't wrap around a line count if it is out of 'int'
17196 range; instead, treat it as an extreme value.
17197 (Fset_window_configuration, compare_window_configurations):
17198 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17200 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17201 that can exceed INT_MAX. Check that EMACS_INT value is in range
17202 before assigning it to the (possibly-narrower) index.
17203 (match_limit): Don't assume that a fixnum can fit in 'int'.
17205 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17208 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17209 (Fvertical_motion): Don't wrap around LINES values that don't fit
17210 in 'int'. Instead, treat them as extreme values. This is good
17211 enough for windows, which can't have more than INT_MAX lines anyway.
17213 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17215 * Require libxml/parser.h to avoid compilation warning.
17217 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17219 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17220 since this reportedly can destroy thread storage.
17222 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17224 * syntax.c (find_defun_start): Update all cache variables if
17225 exiting early (Bug#9401).
17227 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17229 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17231 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17232 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17233 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17235 * term.c (tty_append_glyph): New function.
17236 (produce_stretch_glyph): Static function and its prototype deleted.
17238 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17241 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17243 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17244 when checking :margin (Bug#9390).
17245 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17246 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17247 so that the name doesn't mislead. All uses changed.
17249 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17251 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17254 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17256 * xdisp.c (move_it_to): Don't bail out early when reaching
17257 position beyond to_charpos, if we are scanning backwards.
17258 (move_it_vertically_backward): When DY == 0, make sure we get to
17259 the first character in the line after the newline.
17261 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17263 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17264 (ccl_driver): Do not generate an out-of-range pointer.
17265 (Fccl_execute_on_string): Remove unnecessary check for
17266 integer overflow, noted by Stefan Monnier in
17267 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17268 Remove a FIXME that didn't need fixing.
17269 Simplify the newly-introduced buffer reallocation code.
17271 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17273 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17275 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17277 Integer and memory overflow issues (Bug#9196).
17279 * doc.c (get_doc_string): Rework so that
17280 get_doc_string_buffer_size is the actual buffer size, rather than
17281 being 1 less than the actual buffer size; this makes xpalloc more
17284 * image.c (x_allocate_bitmap_record, cache_image):
17285 * xselect.c (Fx_register_dnd_atom):
17286 Simplify previous changes by using xpalloc.
17288 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17289 since either will do and ptrdiff_t is convenient with xpalloc.
17291 * charset.c (charset_table_size)
17292 (struct charset_sort_data.priority): Now ptrdiff_t.
17293 (charset_compare): Don't overflow if priorities differ greatly.
17294 (Fsort_charsets): Don't assume list length fits in int.
17295 Check for size-calculation overflow when allocating sort data.
17296 (syms_of_charset): Allocate an initial charset table that is
17297 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17299 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17301 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17302 The actual value is always <= INT_MAX, and leaving it unsigned made
17303 overflow checking harder.
17305 * dispextern.h (struct glyph_matrix.rows_allocated)
17306 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17307 with xpalloc. The values are still always <= INT_MAX.
17309 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17311 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17312 (SAFE_NALLOCA): New macro.
17314 * region-cache.c (struct boundary.pos, find_cache_boundary)
17315 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17316 (set_cache_region, invalidate_region_cache)
17317 (revalidate_region_cache, know_region_cache, region_cache_forward)
17318 (region_cache_backward, pp_cache):
17319 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17320 so that ptrdiff_t * can be passed to xpalloc.
17321 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17322 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17323 (pp_cache): Don't assume cache_len fits in int.
17324 * region-cache.h: Adjust extern decls to match.
17326 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17327 EMACS_INT, since either will do, for xpalloc.
17329 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17330 (xnmalloc, xnrealloc, xpalloc): New functions.
17332 * bidi.c (bidi_shelve_header_size): New constant.
17333 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17334 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17336 * bidi.c (bidi_cache_shrink):
17337 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17339 Don't update size of array until after memory allocation succeeds,
17340 because xmalloc/xrealloc may not return.
17341 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17342 now that we have proper integer overflow checking.
17343 (record_overlay_string, overlay_strings): Catch overflows when
17344 calculating size of overlay_str_buf.
17346 * callproc.c (Fcall_process): Check for size overflow when
17347 calculating size of args2.
17348 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

17350 require adding more-complicated checks.
17352 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17353 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

17393 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17395 * emacs.c (main): Do not reallocate argv, since there is a null at
17396 the end that can be overwritten, and this way there's no need to
17397 worry about size-calculation overflow.
17398 (sort_args): Check for size-calculation overflow.
17400 * eval.c (init_eval_once, grow_specpdl): Don't update size until

17406 Check for integer overflow.
17407 (x_set_alpha): Do not assume XINT fits in int.
17409 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17410 This is for the members text_lines, text_cols, total_lines, total_cols,
17411 where the system imposes an 'int' limit.

17420 Check for size-calculation overflow.
17421 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17422 do, as we prefer signed integers.

17527 (X_LONG_MIN): New macros.
17528 Use them to make the following changes clearer.
17529 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

17531 future maintainers not to raise the value too much later.
17532 (SELECTION_QUANTUM): Remove, replacing with ...
17533 (selection_quantum): ... new function, which avoids overflow.
17535 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17536 assumption that selection length fits in 'int'.

17553 Don't store size until memory allocation succeeds.
17554 (x_get_window_property): Plug memory leak on memory exhaustion.
17555 Don't double-block input; malloc is safe here. Don't assume 2**34
17556 - 4 fits in unsigned long. Add an xassert to check
17557 XGetWindowProperty overflow. Be more careful about overflow
17558 calculations, and distinguish size from memory overflow better.
17559 (receive_incremental_selection): When tracing, don't assume
17560 unsigned int is less than INT_MAX.
17561 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17564 in the range -65535 through -1 fit in an X unsigned short.
17565 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17566 result parameters unless successful. Rely on cons_to_unsigned
17567 to report problems with elements; the old code wasn't right anyway.
17568 (x_check_property_data): Check for int overflow; we cannot use
17569 a wider type due to X limits.

17602 * lisp.h (hash_lookup, hash_put):
17603 * minibuf.c (Ftest_completion):
17604 Use ptrdiff_t for hash table indexes, not int (which is too
17605 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17606 32-bit --with-wide-int hosts).
17608 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17609 Add a FIXME comment about memory leaks.

17617 with outlandish widths.
17618 * character.h (sanitize_tab_width): Rename from sanitize_width,
17619 now that we have two such functions. All uses changed.

17638 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17639 (x_send_scroll_bar_event): Likewise. Check that the size does not
17640 exceed limits imposed by XClientMessageEvent, as well as the usual
17641 ptrdiff_t and size_t limits.
17643 * keyboard.c: Overflow, signedness and related fixes.
17644 (make_lispy_movement): Use same integer type in forward decl
17645 that is used in the definition.
17646 (read_key_sequence, keyremap_step):
17647 Change bufsize argument back to int, undoing my 2011-03-30 change.
17648 We prefer signed types, and int is wide enough here.
17649 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17650 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17651 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17652 length, not size_t. Use ptrdiff_t for index, not int.
17653 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17654 possibility of integer overflow.

17682 Prefer int to unsigned where either will do.
17683 (tiff_handler): New function, combining the cores of the
17684 old tiff_error_handler and tiff_warning_handler.
17685 This function is rewritten to use vsnprintf and thereby avoid
17686 stack buffer overflows. It uses only the features of vsnprintf
17687 that are common to both POSIX and native Microsoft.
17688 (tiff_error_handler, tiff_warning_handler): Use it.
17689 (tiff_load, gif_load, imagemagick_load_image):
17690 Don't assume :index value fits in 'int'.

17693 the integer types that MagickCropImage accepts. Don't assume
17694 Vimagemagick_render_type has a nonnegative value. Don't assume
17695 size_t fits in 'long'.
17696 (gs_load): Use printmax_t to print the widest integers possible.

17710 (handle_single_display_spec): If the display spec is of the form
17711 `(space ...)', and specifies display in the text area, return 2
17713 (try_cursor_movement): Check for the need to scroll more
17714 accurately, and prefer exact match for point under bidi.
17715 Don't advance `row' beyond the last row of the window.

17733 buffers, return left-to-right.
17734 (set_cursor_from_row): Consider candidate row a win if its glyph
17735 represents a newline and point is on that newline. Fixes cursor
17736 positioning on the newline at EOL of R2L text within L2R
17737 paragraph, and vice versa.
17738 (try_cursor_movement): Check continued rows, in addition to
17739 continuation rows. Fixes unwarranted scroll when point enters a
17740 continued line of R2L text within an L2R paragraph, or vice versa.
17741 (cursor_row_p): Consider the case of point being equal to
17742 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17743 from the end of a short line to the beginning of a continued line
17744 of R2L text within L2R paragraph.
17745 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

17771 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17772 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17773 candidate is selected by the mouse, and that candidate has a
17774 composed character under the mouse.
17776 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17777 coordinates reported by pos-visible-in-window-p for a composed
17778 character in column zero.
17780 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17782 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17784 2011-08-22 Eli Zaretskii <eliz@gnu.org>

17788 composed buffer positions.
17790 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17792 * image.c (gif_load): Don't assume that each subimage has the same
17793 dimensions as the base image. Handle disposal method that is
17794 "undefined" by the gif spec (Bug#9335).
17796 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17798 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17804 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17805 from an Org mode buffer to a Speedbar frame.
17807 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17808 a composition, take its buffer position from IT->cmp_it.charpos.
17809 Fixes cursor positioning at the beginning of a line that begins
17810 with a composed character.
17812 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17814 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17815 character bidirectional type, use STRONG_L instead. Fixes crashes
17816 in a buffer produced by `describe-categories'.
17818 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17819 members before the level stack, so they would be saved and
17820 restored when copying iterator state. Fixes incorrect reordering
17821 around TABs covered by display properties.
17823 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17825 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17830 (internal_condition_case_2, internal_condition_case_n):
17831 Remove unnecessary aborts (Bug#9081).
17833 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17835 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17836 has no `load' handler, try opening the file locally. (Bug#9311)
17838 2011-08-16 Ken Brown <kbrown@cornell.edu>
17840 * gmalloc.c: Expand comment.
17842 2011-08-16 Eli Zaretskii <eliz@gnu.org>

17856 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17858 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17859 in the static heap.
17860 [CYGWIN] (special_realloc): New function.
17861 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

17877 * chartab.c: Improve commentary for the uniprop_table API.
17879 * bidi.c (bidi_paragraph_init): Support zero value of
17880 bidi_ignore_explicit_marks_for_paragraph_level.

17893 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17895 * xdisp.c (move_it_in_display_line_to): Don't invoke
17896 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17897 ppos_it. Fixes vertical cursor motion when line beginning is
17898 covered by an image. (Bug#9296)
17900 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17902 * nsterm.h (ns_run_ascript): Declare.
17903 (NSAPP_DATA2_RUNASSCRIPT): Define.
17905 * nsfns.m (as_script, as_result, as_status): New static variables.
17906 (ns_run_ascript): New function.
17907 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17908 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17909 the event loop. Get status from as_status (Bug#7276).
17911 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17912 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17913 the event loop (Bug#7276).
17915 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17917 * gnutls.c (QCgnutls_bootprop_priority)

17919 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17920 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17921 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17922 (QCgnutls_bootprop_verify_hostname_error)

17939 (Fnetwork_interface_list): Allocate in increments of bytes instead
17940 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17941 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17943 (struct ifflag_def): notrailers is smart on OSX.
17944 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17945 Get hardware address with getifaddrs if available.
17947 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17949 * xdisp.c (iterate_out_of_display_property): xassert that
17950 IT->position is set to within IT->object's boundaries. Break from
17951 the loop as soon as EOB is reached; avoids infloops in redisplay
17952 when IT->position is set up wrongly due to some bug.
17953 Set IT->current to match the bidi iterator unconditionally.
17954 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17955 entry. Force push_it to save on the stack the current
17956 buffer/string position, to be restored by pop_it. Fix flags in
17957 the iterator structure wrt the object coming from a display
17958 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17959 properties. (Bug#9284)
17961 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17963 * fontset.c (fontset_get_font_group): Add proper type checks.

17976 no-display-properties-and-no-overlays under bidi display.
17977 Set disp_pos in the bidi iterator to avoid searches for display
17978 properties and overlays.
17980 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17982 * editfns.c (Fset_time_zone_rule): Document relationship with the

17991 restore_point_unwind (Bug#5984).
17993 2011-08-07 Juri Linkov <juri@jurta.org>
17995 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17996 to show the arg `TIME' instead of `TIMEVAL'.
17998 2011-08-06 Eli Zaretskii <eliz@gnu.org>
18000 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
18001 display property strides EOL and includes a newline, as in
18002 longlines-mode. (Bug#9254)
18003 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18004 word-wrap under bidirectional display. (Bug#9224)
18006 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18007 is non-zero, even if the data buffer is NULL. Fixes a crash in
18008 vertical-motion with longlines-mode. (Bug#9254)
18010 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18012 * bidi.c <bidi_cache_total_alloc>: Now static.
18013 (bidi_initialize): Initialize bidi_cache_total_alloc.
18015 * xdisp.c (display_line): Release buffer allocated for shelved bidi
18018 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18019 amount allocated this far in `bidi_cache_total_alloc'.
18020 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18021 non-zero, only free the data buffer without restoring the cache
18022 contents. All callers changed.
18024 * dispextern.h (bidi_unshelve_cache): Update prototype.
18026 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
18027 (move_it_in_display_line, move_it_to)
18028 (move_it_vertically_backward, move_it_by_lines): Replace the call
18029 to xfree to an equivalent call to bidi_unshelve_cache.
18030 (move_it_in_display_line_to): Fix logic of returning
18031 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
18033 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18035 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
18036 came from a string character with a `cursor' property. (Bug#9229)
18038 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18040 * Makefile.in (LIB_PTHREAD): New variable.
18041 (LIBES): Add LIB_PTHREAD (Bug#9216).
18043 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
18044 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
18046 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
18048 * regex.c (re_iswctype): Remove some redundant boolean conversions.
18050 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18052 * xterm.c (x_find_topmost_parent): New function.
18053 (x_set_frame_alpha): Find topmost parent window with
18054 x_find_topmost_parent and set the property there also (bug#9181).
18055 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
18057 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

18068 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
18069 so that it is not optimized away.
18071 * xdisp.c (compute_display_string_pos): Remove unused local.
18073 2011-08-02 Eli Zaretskii <eliz@gnu.org>
18075 Fix slow cursor motion and scrolling in large buffers with
18076 selective display, like Org Mode buffers. (Bug#9218)
18078 * dispextern.h (struct bidi_it): New member disp_prop_p.
18080 * xdisp.c: Remove one-slot cache of display string positions.
18081 (compute_display_string_pos): Accept an additional argument

18083 for a display string or property. If found, set DISP_PROP_P
18086 * bidi.c (bidi_fetch_char): Accept an additional argument
18087 DISP_PROP_P, and pass it to compute_display_string_pos.
18088 Only handle text covered by a display string if DISP_PROP_P is returned
18089 non-zero. All callers of bidi_fetch_char changed.
18091 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
18093 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
18095 2010-12-03 Don March <don@ohspite.net>
18097 * keymap.c (Fdefine_key): Fix non-prefix key error message when
18098 last character M-[char] is translated to ESC [char] (bug#7541).
18100 2011-08-02 Kenichi Handa <handa@m17n.org>
18102 * lisp.h (uniprop_table): Extern it.
18104 * chartab.c (uniprop_table): Make it non-static.
18106 2011-08-01 Eli Zaretskii <eliz@gnu.org>
18108 * xdisp.c (forward_to_next_line_start): Accept additional argument
18109 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18111 (reseat_at_next_visible_line_start): Use the bidi iterator state
18112 returned by forward_to_next_line_start to restore the state of
18113 it->bidi_it after backing up to previous newline. (Bug#9212)
18115 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18117 * regex.c (re_comp): Protoize.
18118 (re_exec): Fix return type.
18119 (regexec): Fix type of `ret'. (Bug#9203)
18121 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18123 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18124 This is needed if max-image-size is a floating-point number.
18126 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18128 * print.c (print_object): Print empty symbol as ##.

18139 contents (Bug#9176).
18140 (EmacsTooltip -init): Remove bezels and add shadows to
18143 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18144 or scroll bar (Bug#8470).
18146 * nsfont.m (nsfont_open): Remove assignment to voffset and
18147 unnecessary vars hshink, expand, hd, full_height, min_height.

18150 * nsterm.h (nsfont_info): Remove voffset field.
18152 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18154 Implement strike-through and overline on NextStep (Bug#8863).
18156 * nsfont.m (nsfont_open): Use underline position provided by font,
18157 instead of hard-coded value of 2.
18158 (nsfont_draw): Call ns_draw_text_decoration instead.

18168 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18170 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18173 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18175 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18176 Without this fix, if a signal arrives just after memory fills up,
18177 'malloc' might be invoked reentrantly.
18179 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18180 In other words, assume that every image size is allowed, on non-X
18181 hosts. This assumption is probably wrong, but it lets Emacs compile.
18183 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18185 * regex.c (re_iswctype): Convert return values to boolean.
18187 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18189 * xdisp.c (compute_display_string_pos): Don't use cached display
18190 string position if the buffer had its restriction changed.
18193 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18195 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18197 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18199 Integer signedness and overflow and related fixes. (Bug#9079)
18201 * bidi.c: Integer size and overflow fixes.
18202 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18203 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18204 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18205 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18206 (bidi_find_other_level_edge):
18207 Use ptrdiff_t instead of EMACS_INT where either will do.
18208 This works better on 32-bit hosts configured --with-wide-int.
18209 (bidi_cache_ensure_space): Check for size-calculation overflow.
18210 Use % rather than repeated addition, for better worst-case speed.
18211 Don't set bidi_cache_size until after xrealloc returns, because it
18213 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18214 (bidi_cache_ensure_space): Also check that the bidi cache size
18215 does not exceed that of the largest Lisp string or buffer. See Eli
18216 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18218 * alloc.c (__malloc_size_t): Remove.
18219 All uses replaced by size_t. See Andreas Schwab's note
18220 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18222 * image.c: Improve checking for integer overflow.
18223 (check_image_size): Assume that f is nonnull, since
18224 it is always nonnull in practice. This is one less thing to
18225 worry about when checking for integer overflow later.
18226 (x_check_image_size): New function, which checks for integer
18227 overflow issues inside X.
18228 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18229 This removes the need for a memory_full check.
18230 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18231 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18232 (xbm_read_bitmap_data): Change locals back to 'int', since
18233 their values must fit in 'int'.
18234 (xpm_load_image, png_load, tiff_load):
18235 Invoke x_create_x_image_and_pixmap earlier,
18236 to avoid much needless work if the image is too large.
18237 (tiff_load): Treat overly large images as if
18238 x_create_x_image_and_pixmap failed, not as malloc failures.
18239 (gs_load): Use x_check_image_size.
18241 * gtkutil.c: Omit integer casts.
18242 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18243 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18245 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18247 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18248 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18249 would wrongly return t on a 64-bit host.
18251 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18252 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18253 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18254 and therefore cause GCC to emit a bogus diagnostic in some cases.
18256 * image.c: Integer signedness and overflow and related fixes.
18257 This is not an exhaustive set of fixes, but it's time to
18258 record what I've got.
18259 (lookup_pixel_color, check_image_size): Remove redundant decls.
18260 (check_image_size): Don't assume that arbitrary EMACS_INT values
18261 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18262 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18263 (tiff_load, imagemagick_load_image):
18264 Check for overflow in size calculations.
18265 (x_create_x_image_and_pixmap): Remove unnecessary test for
18266 xmalloc returning NULL; that can't happen.
18267 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18268 (xpm_color_bucket): Use better integer hashing function.
18269 (xpm_cache_color): Don't possibly over-allocate memory.
18270 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18271 (gif_memory_source):
18272 Use ptrdiff_t, not int or size_t, to record sizes.
18273 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18274 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18275 either works, as we prefer signed integers.
18276 (tiff_read_from_memory, tiff_write_from_memory):
18277 Return tsize_t, not size_t, since that's what the TIFF API wants.
18278 (tiff_read_from_memory): Don't fail simply because the read would
18279 go past EOF; instead, return a short read.
18280 (tiff_load): Omit no-longer-needed casts.
18281 (Fimagemagick_types): Don't assume size fits into 'int'.
18283 Improve hashing quality when configured --with-wide-int.
18284 * fns.c (hash_string): New function, taken from sxhash_string.
18285 Do not discard information about ASCII character case; this
18286 discarding is no longer needed.
18287 (sxhash-string): Use it. Change sig to match it. Caller changed.
18288 * lisp.h: Declare it.
18289 * lread.c (hash_string): Remove, since we now use fns.c's version.
18290 The fns.c version returns a wider integer if --with-wide-int is
18291 specified, so this should help the quality of the hashing a bit.
18293 * emacs.c: Integer overflow minor fix.
18294 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18295 Define only if GNU_LINUX.
18296 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18298 * dispnew.c: Integer signedness and overflow fixes.
18299 Remove unnecessary forward decls, that were a maintenance hassle.
18300 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18302 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18303 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18304 (prepare_desired_row, line_draw_cost):
18305 Use int, not unsigned, where either works.
18306 (save_current_matrix, restore_current_matrix):
18307 Use ptrdiff_t, not size_t, where either works.
18308 (init_display): Check for overflow more accurately, and without
18309 relying on undefined behavior.
18311 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18312 Remove, replacing with the new symbols in lisp.h. All uses changed.
18313 * fileio.c (make_temp_name):
18314 * filelock.c (lock_file_1, lock_file):
18315 * xdisp.c (message_dolog):
18316 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18317 Use pMd etc. instead.
18318 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18319 replacing the pWIDE etc. symbols removed from editfns.c.
18321 * keyboard.h (num_input_events): Now uintmax_t.
18322 This is (very slightly) less likely to mess up due to wraparound.
18325 * buffer.c: Integer signedness fixes.
18326 (alloc_buffer_text, enlarge_buffer_text):
18327 Use ptrdiff_t rather than size_t when either will do, as we prefer
18330 * alloc.c: Integer signedness and overflow fixes.
18331 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18332 (__malloc_size_t): Default to size_t, not to int.
18333 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18334 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18335 Prefer ptrdiff_t to size_t when either would do, as we prefer
18337 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18338 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18339 Now const. Initialize with values that are in range even if char
18341 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18342 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18343 These functions do the right thing with sizes > 2**32.
18344 (check_depth): Now ptrdiff_t, not int.
18345 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18346 Adjust to new way of storing sizes. Check for size overflow bugs
18348 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18349 slightly wrong anyway, as it missed one instance of
18350 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18351 (refill_memory_reserve): Omit needless cast to size_t.
18352 (mark_object_loop_halt): Mark as externally visible.
18354 * xselect.c: Integer signedness and overflow fixes.
18355 (Fx_register_dnd_atom, x_handle_dnd_message):
18356 Use ptrdiff_t, not size_t, since we prefer signed.
18357 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18358 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18359 x_dnd_atoms_size and x_dnd_atoms_length.
18361 * doprnt.c: Prefer signed to unsigned when either works.
18363 * doprnt.c (doprnt):
18365 * xdisp.c (vmessage):
18366 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18367 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18368 prefer signed arithmetic to avoid comparison confusion.
18369 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18370 but is a bit tricky.
18372 Assume freestanding C89 headers, string.h, stdlib.h.
18373 * data.c, doprnt.c, floatfns.c, print.c:
18374 Include float.h unconditionally.
18375 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18376 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18377 * regex.c: Likewise for stddef.h, string.h.
18378 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18379 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18380 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18381 (STDC_HEADERS): Remove obsolete defines.
18382 * sysdep.c: Include limits.h unconditionally.
18384 Assume support for memcmp, memcpy, memmove, memset.
18385 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18386 * regex.c (memcmp, memcpy):
18387 Remove; we assume C89 now.
18389 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18390 (__malloc_safe_bcopy): Remove; no longer needed.
18392 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18393 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18394 well either way, and we prefer signed to unsigned.
18396 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18398 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18399 closes the connection while we're reading (bug#9182).
18401 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18403 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18404 are specified (Bug#9168).
18406 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18408 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18409 Found by GCC static checking and --with-wide-int on a 32-bit host.
18411 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18413 * xdisp.c (compute_display_string_pos): Fix logic of caching
18414 previous display string position. Initialize cached_prev_pos to
18415 -1. Fixes slow-down at the beginning of a buffer.
18417 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18419 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18420 for attrs[LFACE_FONTSET_INDEX].
18422 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18424 * xml.c (parse_region): Remove unused local
18425 that was recently introduced.
18427 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18429 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18430 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18432 * xdisp.c (move_it_in_display_line_to): Record the best matching
18433 position for TO_CHARPOS while scanning the line, and restore it on
18434 exit if none of the characters scanned was an exact match.
18435 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18436 when exact match is impossible due to invisible text, and the
18437 lines are truncated.
18439 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18441 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18444 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18446 Fix a significant slow-down of cursor motion with C-n, C-p,
18447 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18448 auto-repeat under bidi redisplay in fontified buffers.
18449 * xdisp.c (compute_stop_pos_backwards): New function.
18450 (next_element_from_buffer): Call compute_stop_pos_backwards to
18451 find a suitable prev_stop when we find ourselves before
18453 (reseat): Don't look for prev_stop, as that could mean a very long
18455 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18456 <cached_disp_overlay_modiff>: Cache for last found display string
18458 (compute_display_string_pos): Return the cached position if asked
18459 about the same buffer in the same area of character positions, and
18460 the buffer wasn't changed since the time the display string
18461 position was cached.
18463 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18465 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18466 is an integer, which is important for empty lines. (Bug#9149)
18468 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18470 * frame.c (Fmodify_frame_parameters): In tty case, update the
18471 default face if necessary (Bug#4238).
18473 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18475 * editfns.c (Fstring_to_char): No need to explain what a character
18476 is in the docstring (Bug#6576).
18478 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18480 * xml.c (parse_region): Make sure we always return a tree.
18482 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18484 * xml.c (parse_region): If a document contains only comments,
18487 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18489 * xml.c (make_dom): Return comments, too.
18491 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18494 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18495 and the surrounding thread.
18496 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18497 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18498 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18500 * s/openbsd.h (BROKEN_SIGIO): Define.
18501 * unexelf.c (unexec) [__OpenBSD__]:
18502 Don't update the .mdebug section of the Alpha COFF symbol table.
18504 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18506 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18509 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18511 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18512 This fixes some race conditions on the permissions of any newly
18515 * alloc.c (valid_pointer_p): Use pipe, not open.
18516 This fixes some permissions issues when debugging.
18518 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18519 If fchown fails to set both uid and gid, try to set just gid,
18520 as that is sometimes allowed. Adjust the file's mode to eliminate
18521 setuid or setgid bits that are inappropriate if fchown fails.
18523 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18525 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18526 to compare Lisp_Objects.
18527 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18528 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18529 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18531 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18533 * lread.c (read_integer): Unread even EOF character.
18534 (read1): Likewise. Properly record start position of symbol.
18536 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18537 symbol character follows.
18539 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18541 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18542 This works around a problem with the previous change to Fcopy_file.
18543 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18544 and without this change, GCC might complain about discarding
18545 fchown's return value.
18547 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18549 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18551 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18553 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18555 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18557 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18558 it's used from the C level.
18560 * process.c: Use the same condition for POLL_FOR_INPUT in both
18561 keyboard.c and process.c (bug#1858).
18563 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18565 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18566 (Fgnutls_boot): Use it.
18568 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18570 * doc.c (Fsubstitute_command_keys): Revert last change.
18572 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18574 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18575 quotes the next character, and doesn't affect other longer
18576 sequences (bug#8935).
18578 * lread.c (syms_of_lread): Clarify that is isn't only
18579 `eval-buffer' and `eval-defun' that's affected by
18580 `lexical-binding' (bug#8460).
18582 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18584 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18585 bidi redisplay when a line includes both an image and is truncated.
18587 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18589 Fix minor problems found by static checking.
18590 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18591 (elsz): Now a signed constant, not a size_t var. We prefer signed
18592 types to unsigned, to avoid integer comparison confusion. Without
18593 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18594 "cannot optimize loop, the loop counter may overflow", a symptom
18596 * indent.c (Fvertical_motion): Mark locals as initialized.
18597 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18599 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18601 * search.c (Fre_search_backward): Mention `case-fold-search' in
18602 all the re_search_* functions (bug#8138).
18604 * keyboard.c (Fopen_dribble_file): Document when the file is
18607 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18609 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18612 Support bidi reordering of display and overlay strings.
18613 * xdisp.c (compute_display_string_pos)
18614 (compute_display_string_end): Accept additional argument STRING.
18615 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18616 (reseat_to_string): Initialize bidi_it->string.s and
18617 bidi_it->string.schars.
18618 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18619 NULL (avoids a crash in bidi_paragraph_init).
18620 Initialize itb.string.lstring.
18621 (init_iterator): Call bidi_init_it only of a valid
18622 buffer position was specified. Initialize paragraph_embedding to
18624 (reseat_to_string): Initialize the bidi iterator.
18625 (display_string): If we need to ignore text properties of
18626 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18627 original value of -1 will not work with bidi.)
18628 (compute_display_string_pos): First arg is now struct
18629 `text_pos *'; all callers changed. Support display properties on
18631 (compute_display_string_end): Support display properties on Lisp
18633 (init_iterator, reseat_1, reseat_to_string): Initialize the
18634 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18635 when iterating on a string not from display properties).
18636 (compute_display_string_pos, compute_display_string_end):
18637 Fix calculation of the object to scan. Fixes an error when using
18639 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18640 base_level_stop; instead, set base_level_stop to BEGV.
18641 Fixes crashes in vertical-motion.
18642 (next_element_from_buffer): Improve commentary for when
18643 the iterator is before prev_stop.
18644 (init_iterator): Initialize bidi_p from the default value of
18645 bidi-display-reordering, not from buffer-local value. Use the
18646 buffer-local value only if initializing for buffer iteration.
18647 (handle_invisible_prop): Support invisible properties on strings
18648 that are being bidi-reordered.
18649 (set_iterator_to_next): Support bidi reordering of C strings and
18651 (next_element_from_string): Support bidi reordering of Lisp
18653 (handle_stop_backwards): Support Lisp strings as well.
18654 (display_string): Support display of R2L glyph rows.
18655 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18656 (init_iterator): Don't initialize it->bidi_p for strings
18658 (reseat_to_string): Initialize it->bidi_p for strings here.
18659 (next_element_from_string, next_element_from_c_string)
18660 (next_element_from_buffer): Add xassert's for correspondence
18661 between IT's object being iterated and it->bidi_it.string
18663 (face_before_or_after_it_pos): Support bidi iteration.
18664 (next_element_from_c_string): Handle the case of the first string
18665 character that is not the first one in the visual order.
18666 (get_visually_first_element): New function, refactored from common
18667 parts of next_element_from_buffer, next_element_from_string, and
18668 next_element_from_c_string.
18669 (tool_bar_lines_needed, redisplay_tool_bar)
18670 (display_menu_bar): Force left-to-right direction. Add a FIXME
18671 comment for making that be controlled by a user option.
18672 (push_it, pop_it): Save and restore the state of the
18673 bidi iterator. Save and restore the bidi_p flag.
18674 (pop_it): Iterate out of display property for string iteration as
18676 (iterate_out_of_display_property): Support iteration over strings.
18677 (handle_single_display_spec): Set up it->bidi_it for iteration
18678 over a display string, and call bidi_init_it.
18679 (handle_single_display_spec, next_overlay_string)
18680 (get_overlay_strings_1, push_display_prop): Set up the bidi
18681 iterator for displaying display or overlay strings.
18682 (forward_to_next_line_start): Don't use the shortcut if

19119 * alloc.c (mark_buffer):
19120 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
19121 (clone_per_buffer_values): Don't assume that
19122 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
19123 This isn't true in general, and it's particularly not true
19124 if Emacs is configured with --with-wide-int.
19125 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
19126 New macros, used in the buffer.c change.
19128 2011-07-05 Jan Djärv <jan.h.d@swipnet.se>

19133 (store_tool_bar_style_changed): New functions.
19134 (store_monospaced_changed): Add comment. Call dpyinfo_valid.
19135 (struct xsettings): Move font inside HAVE_XFT.
19136 (GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
19137 (GSETTINGS_MONO_FONT): Rename from SYSTEM_MONO_FONT.
19138 Move inside HAVE_XFT.
19139 (something_changed_gsettingsCB): Rename from something_changedCB.
19140 Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME
19142 (GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.

19146 (parse_settings): Move check for font inside HAVE_XFT.
19147 (read_settings, apply_xft_settings): Add comment.
19148 (read_and_apply_settings): Add comment. Call map_tool_bar_style and
19149 store_tool_bar_style_changed. Move check for font inside HAVE_XFT and
19150 call store_font_name_changed.
19151 (xft_settings_event): Add comment.
19152 (init_gsettings): Add comment. Get values for GSETTINGS_TOOL_BAR_STYLE
19153 and GSETTINGS_FONT_NAME. Move check for fonts within HAVE_XFT.

19160 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
19162 Random fixes. E.g., (random) never returned negative values.
19163 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19164 subseconds part to the entropy, as that's a bit more random.
19165 Prefer signed to unsigned, since the signedness doesn't matter and
19166 in general we prefer signed. When given a limit, use a
19167 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19168 latter isn't right if USE_2_TAGS_FOR_INTS.
19169 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19170 not 0..VALMASK. Don't discard "excess" bits that random () returns.
19172 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
19174 * textprop.c (text_property_stickiness):
19175 Obey Vtext_property_default_nonsticky.
19176 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
19177 * w32fns.c (syms_of_w32fns):

19180 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
19182 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19183 This is more efficient than Ffile_directory_p and avoids a minor race.
19185 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19187 * buffer.c (Foverlay_put): Say what the return value is
19190 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19191 is a directory before asking whether to use the file name
19193 (barf_or_query_if_file_exists): Make the "File is a directory"
19194 error be more correct.
19196 * fns.c (Frequire): Remove the mention of the .gz files, since
19197 that's installation-specific, but keep the mention of
19198 `get-load-suffixes'.
19200 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
19202 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

19208 (syms_of_gnutls): Remove duplicate DEFSYM for
19209 Qgnutls_bootprop_verify_hostname_error, an error for
19210 Qgnutls_bootprop_verify_error (which is no longer used).
19212 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19213 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19214 Also (re)move comments that are misplaced or no longer relevant.
19216 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
19218 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
19220 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
19222 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
19223 and background color parameters if they have been changed.

19236 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
19238 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
19239 leave any prefix arg for the up event (Bug#1586).

19243 * lread.c (syms_of_lread): Mention single symbols defined by
19244 `defvar' or `defconst' (bug#7154).
19246 * fns.c (Frequire): Mention .el.gz files (bug#7314).
19247 (Frequire): Mention get-load-suffixes.

19277 (syms_of_keymap): Defsubr make-composed-keymap.
19278 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

19315 * eval.c (struct backtrace): Simplify and port the data structure.
19316 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19317 signed bit field, as this assumption is not portable and it makes
19318 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19319 "char debug_on_exit : 1" as this is not portable either; instead,
19320 use the portable "unsigned int debug_on_exit : 1". Remove unused
19321 member evalargs. Remove obsolete comments about cc bombing out.
19323 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
19325 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

19556 on undefined behavior with wrong number of arguments.
19557 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19558 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19559 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19560 since we're not interested in debugging glyphs with old libraries.
19561 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19562 GCC 4.6.0's static checking.
19564 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19566 Integer overflow and signedness fixes (Bug#8873).
19567 A few related buffer overrun fixes, too.
19569 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
19571 * dispextern.h (struct face.stipple):
19572 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
19573 (x_bitmap_mask, x_allocate_bitmap_record)
19574 (x_create_bitmap_from_data, x_create_bitmap_from_file)
19575 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19576 (x_create_bitmap_from_xpm_data):
19577 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19578 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19580 * xfaces.c (load_pixmap):
19581 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19582 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19583 (.bitmaps_last, struct x_output.icon_bitmap):
19584 Use ptrdiff_t, not int, for bitmap indexes.
19585 (x_allocate_bitmap_record): Check for size overflow.
19586 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19588 Use ptrdiff_t, not int, for overlay counts.
19589 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19590 * editfns.c (overlays_around, get_pos_property):
19591 * textprop.c (get_char_property_and_overlay):
19592 * xdisp.c (next_overlay_change, note_mouse_highlight):
19593 * xfaces.c (face_at_buffer_position):
19594 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19595 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19596 (Fnext_overlay_change, Fprevious_overlay_change)
19597 (mouse_face_overlay_overlaps, Foverlays_in):
19598 Use ptrdiff_t, not int, for sizes.
19599 (overlays_at, overlays_in): Check for size-calculation overflow.
19601 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19603 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19604 (x_session_initialize): Do not assume string length fits in int.
19606 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19607 This is unlikely, but can occur if DPI is outlandish.
19609 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19610 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19612 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19613 * xrdb.c (magic_file_p, search_magic_path):
19614 Omit last arg SUFFIX; it was always 0. All callers changed.
19615 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19617 * xfont.c (xfont_match): Avoid need for strlen.
19619 * xfns.c: Don't assume strlen fits in int.
19620 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19622 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19623 not unsigned long, as we prefer signed integers. All callers changed.
19624 Detect integer overflow in repeat count.
19625 (message_dolog): Don't assume print length fits in 39 bytes.
19626 (display_mode_element): Don't assume strlen fits in int.
19628 * termcap.c: Don't assume sizes fit in int and never overflow.
19629 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19630 (gobble_line): Check for size-calculation overflow.
19632 * minibuf.c (Fread_buffer):
19633 * lread.c (intern, intern_c_string):
19634 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19635 Don't assume string length fits in int.
19637 * keyboard.c (parse_tool_bar_item):
19638 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19640 * font.c: Don't assume string length fits in int.
19641 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19642 Use ptrdiff_t, not int.
19643 (font_intern_prop): Don't assume string length fits in int.
19644 Don't assume integer property fits in fixnum.
19645 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19647 * filelock.c: Fix some buffer overrun and integer overflow issues.
19648 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19649 Reformulate so as not to need the command string.
19650 Invoke gzip -cd rather than gunzip, as it's more portable.
19651 (lock_info_type, lock_file_1, lock_file):
19652 Don't assume pid_t and time_t fit in unsigned long.
19653 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19654 (current_lock_owner): Prefer signed type for sizes.
19655 Use memcpy, not strncpy, where memcpy is what is really wanted.
19656 Don't assume (via atoi) that time_t and pid_t fit in int.
19657 Check for time_t and/or pid_t out of range, e.g., via a network share.
19658 Don't alloca where an auto var works fine.
19660 * fileio.c: Fix some integer overflow issues.
19661 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19662 Don't assume string length fits in int.
19663 (directory_file_name): Don't assume string length fits in long.
19664 (make_temp_name): Don't assume pid fits in int, or that its print
19665 length is less than 20.
19667 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19669 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19671 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19673 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19674 We prefer signed integers, even for size calculations.
19676 * emacs.c: Don't assume string length fits in 'int'.
19677 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19678 (main): Don't invoke strlen when not needed.
19680 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19681 (XD_DEBUG_MESSAGE): Don't waste a byte.
19683 * callproc.c (getenv_internal_1, getenv_internal)
19684 (Fgetenv_internal):
19685 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19687 * lread.c (invalid_syntax): Omit length argument.
19688 All uses changed. This doesn't fix a bug, but it simplifies the
19689 code away from its former Hollerith-constant appearance, and it's
19690 one less 'int' to worry about when looking at integer-overflow issues.
19691 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19693 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19694 This didn't break anything, but it didn't help either.
19695 It's confusing to put a bogus integer in a place where the actual
19696 value does not matter.
19697 (LIST_END_P): Remove unused macro and its bogus comment.
19698 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19700 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19701 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19703 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19704 We prefer signed types, and the value cannot exceed the EMACS_INT
19705 range anyway (because otherwise the length would not be representable).
19706 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19707 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19708 This avoids a GCC warning when WIDE_EMACS_INT.
19710 * indent.c (sane_tab_width): New function.
19711 (current_column, scan_for_column, Findent_to, position_indentation)
19712 (compute_motion): Use it. This is just for clarity.
19713 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19715 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19717 * lisp.h (lint_assume): New macro.
19718 * composite.c (composition_gstring_put_cache):
19719 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19721 * editfns.c, insdel.c:
19722 Omit unnecessary forward decls, to simplify future changes.
19724 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19726 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19728 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19729 Use much-faster test for byte-length change.
19730 Don't assume string byte-length fits in 'int'.
19731 Check that character arg fits in 'int'.
19732 (mapcar1): Declare byte as byte, for clarity.
19734 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19736 * fns.c (concat): Catch string overflow earlier.
19737 Do not rely on integer wraparound.
19739 * dispextern.h (struct it.overlay_strings_charpos)
19740 (struct it.selective): Now EMACS_INT, not int.
19741 * xdisp.c (forward_to_next_line_start)
19742 (back_to_previous_visible_line_start)
19743 (reseat_at_next_visible_line_start, next_element_from_buffer):
19744 Don't arbitrarily truncate the value of 'selective' to int.
19746 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19748 * composite.c: Don't truncate sizes to 'int'.
19749 (composition_gstring_p, composition_reseat_it)
19750 (composition_adjust_point): Use EMACS_INT, not int.
19751 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19752 not EMACS_UINT, for indexes.
19754 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19756 * buffer.c: Include <verify.h>.
19757 (struct sortvec.priority, struct sortstr.priority):
19758 Now EMACS_INT, not int.
19759 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19760 (struct sortstr.size, record_overlay_string)
19761 (struct sortstrlist.size, struct sortlist.used):
19762 Don't truncate size to int.
19763 (record_overlay_string): Check for size-calculation overflow.
19764 (init_buffer_once): Check at compile-time, not run-time.
19766 2011-06-22 Jim Meyering <meyering@redhat.com>
19768 Don't leak an XBM-image-sized buffer
19769 * image.c (xbm_load): Free the image buffer after using it.
19771 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19774 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19775 that Sun C diagnosed.
19776 * fns.c (secure_hash): Fix pointer signedness issue.
19777 * intervals.c (static_offset_intervals): New function.
19778 (offset_intervals): Use it.
19780 2011-06-21 Leo Liu <sdl.web@gmail.com>
19783 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19786 * fns.c (secure_hash): Rename from crypto_hash_function and change
19787 the first arg to accept symbols.
19788 (Fsecure_hash): New primitive.
19789 (syms_of_fns): New symbols.
19791 2011-06-20 Deniz Dogan <deniz@dogan.se>
19793 * process.c (Fset_process_buffer): Clarify return value in
19796 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19798 * dispnew.c (add_window_display_history): Use BVAR.
19800 * xdisp.c (debug_method_add): Use BVAR.
19801 (check_window_end, dump_glyph_matrix, dump_glyph)
19802 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19804 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19807 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19808 check till after the cache is created in init_frame_faces.
19810 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19812 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19814 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19816 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19817 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19818 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19820 Improve buffer-overflow checking (Bug#8873).
19821 * fileio.c (Finsert_file_contents):
19822 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19823 Remove the old (too-loose) buffer overflow checks.
19824 They weren't needed, since make_gap checks for buffer overflow.
19825 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19826 The old code merely checked for Emacs fixnum overflow, and relied
19827 on undefined (wraparound) behavior. The new code avoids undefined
19828 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19830 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19831 Tune. Don't use wider integers than needed. Don't use alloca.
19832 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19834 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19836 * insdel.c, lisp.h (buffer_overflow): New function.
19837 (insert_from_buffer_1, replace_range, replace_range_2):
19838 * insdel.c (make_gap_larger):
19839 * editfns.c (Finsert_char):
19840 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19842 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19844 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19846 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19848 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19849 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19851 * fileio.c: Don't assume EMACS_INT fits in off_t.
19852 (emacs_lseek): New static function.
19853 (Finsert_file_contents, Fwrite_region): Use it.
19854 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19856 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19858 * fns.c: Don't overflow int when computing a list length.
19859 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19860 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19861 truncation on 64-bit hosts. Check for QUIT every
19862 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19863 faster and is responsive enough.
19864 (Flength): Report an error instead of overflowing an integer.
19865 (Fsafe_length): Return a float if the value is not representable
19866 as a fixnum. This shouldn't happen except in contrived situations.
19867 (Fnthcdr, Fsort): Don't assume list length fits in int.
19868 (Fcopy_sequence): Don't assume vector length fits in int.
19870 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19871 (header_size, word_size): New constants.
19872 (allocate_vectorlike): Don't check size overflow here.
19873 (allocate_vector): Check it here instead, since this is the only
19874 caller of allocate_vectorlike that could cause overflow.
19875 Check that the new vector's length is representable as a fixnum.
19877 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19878 The previous code was bogus. For example, next_almost_prime (32)
19879 returned 39, which is undesirable as it is a multiple of 3; and
19880 next_almost_prime (24) returned 25, which is a multiple of 5 so
19881 why was the code bothering to check for multiples of 7?
19883 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19885 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19887 Variadic C functions now count arguments with ptrdiff_t.
19888 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19889 Back then I didn't know that the Emacs coding style prefers signed int.
19890 Also, in the meantime I found a few more instances where arguments
19891 were being counted with int, which may truncate counts on 64-bit
19892 machines, or EMACS_INT, which may be unnecessarily wide.
19893 * lisp.h (struct Lisp_Subr.function.aMANY)
19894 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19895 Arg counts are now ptrdiff_t, not size_t.
19896 All variadic functions and their callers changed accordingly.
19897 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19898 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19899 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19900 * callint.c (Fcall_interactively): Check arg count for overflow,
19901 to avoid potential buffer overrun. Use signed char, not 'int',
19902 for 'varies' array, so that we needn't bother to check its size
19903 calculation for overflow.
19904 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19905 * eval.c (apply_lambda):
19906 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19907 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19908 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19910 * callint.c (Fcall_interactively): Don't use index var as event count.
19912 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19913 * mem-limits.h (SIZE): Remove; no longer used.
19915 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19917 Remove unnecessary casts.
19918 * xterm.c (x_term_init):
19919 * xfns.c (x_set_border_pixel):
19920 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19921 These aren't needed now that we assume ANSI C.
19923 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19924 It's more likely to cause problems (due to unsigned overflow)
19927 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19929 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19931 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19933 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19935 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19937 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19939 GLYPH_CODE_FACE returns EMACS_INT, not int.
19940 * dispextern.h (merge_faces):
19941 * xfaces.c (merge_faces):
19942 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19943 Don't assume EMACS_INT fits in int.
19945 * character.h (CHAR_VALID_P): Remove unused parameter.
19946 * fontset.c, lisp.h, xdisp.c: All uses changed.
19948 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19950 * fns.c (concat): Minor tuning based on overflow analysis.
19951 This doesn't fix any bugs. Use int to hold character, instead
19952 of constantly refetching from Emacs object. Use XFASTINT, not
19953 XINT, for value known to be a character. Don't bother comparing
19954 a single byte to 0400, as it's always less.
19956 * floatfns.c (Fexpt):
19957 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19959 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19962 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19964 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19965 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19966 incorrectly succeed when S was a string, because 4294967386 was
19967 truncated before it was used.
19969 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19970 Otherwise, an out-of-range integer could cause undefined behavior
19973 * composite.c: Use int, not EMACS_INT, for characters.
19974 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19975 EMACS_INT, for values that are known to be in character range.
19976 This doesn't fix any bugs but is the usual style inside Emacs and
19977 may generate better code on 32-bit machines.
19979 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19980 This is for reasons similar to the recent CHAR_STRING fix.
19981 * charset.c (Fencode_char): Check that character arg is actually
19982 a character. Pass an int to ENCODE_CHAR.
19983 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19984 wider than 'int', as a compile-time check to prevent future regressions
19987 * character.c (char_string): Remove unnecessary casts.
19989 Make sure a 64-bit char is never passed to CHAR_STRING.
19990 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19991 by silently ignoring the top 32 bits, allowing some values
19992 that were far too large to be valid characters.
19993 * character.h: Include <verify.h>.
19994 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19995 arguments are no wider than unsigned, as a compile-time check
19996 to prevent future regressions in this area.
19998 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19999 (Fsubst_char_in_region):
20001 * xdisp.c (decode_mode_spec_coding):
20002 Adjust to CHAR_STRING's new requirement.
20003 * editfns.c (Finsert_char, Fsubst_char_in_region):
20004 * fns.c (concat): Check that character args are actually
20005 characters. Without this test, these functions did the wrong
20006 thing with wildly out-of-range values on 64-bit hosts.
20008 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20009 These casts should not be needed on 32-bit hosts, either.
20010 * keyboard.c (read_char):
20011 * lread.c (Fload): Remove casts to unsigned.
20013 * lisp.h (UNSIGNED_CMP): New macro.

20020 * dispextern.h (FACE_FROM_ID):
20021 * keyboard.c (read_char): Use UNSIGNED_CMP.
20023 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20024 not to EMACS_INT, to avoid GCC warning.
20026 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20028 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20029 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20030 isn't needed on 32-bit machines.
20032 * buffer.c (Fgenerate_new_buffer_name):
20033 Use EMACS_INT for count, not int.
20034 (advance_to_char_boundary): Return EMACS_INT, not int.

20053 (total_free_floats, total_floats, total_free_intervals)
20054 (total_intervals, total_strings, total_free_strings):
20055 Now EMACS_INT, not int. All uses changed.
20056 (Fgarbage_collect): Compute overall total using a double, so that
20057 integer overflow is less likely to be a problem. Check for overflow
20058 when converting back to an integer.
20059 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20060 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20061 These were 'int' variables that could overflow on 64-bit hosts;
20062 they were never used, so remove them instead of repairing them.
20063 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20064 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20065 Previously, this ceilinged at INT_MAX, but that doesn't work on
20067 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20069 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20070 (allocate_vectorlike): Check for ptrdiff_t overflow.
20071 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20072 when a (possibly-narrower) signed value would do just as well.
20073 We prefer using signed arithmetic, to avoid comparison confusion.
20075 * alloc.c: Catch some string size overflows that we were missing.
20076 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20077 for convenience in STRING_BYTES_MAX.
20078 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20079 The definition here is exact; the one in lisp.h was approximate.
20080 (allocate_string_data): Check for string overflow. This catches
20081 some instances we weren't catching before. Also, it catches
20082 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20083 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20084 and ptrdiff_t and EMACS_INT are both 64 bits.
20086 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20087 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20088 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20090 * character.c (string_escape_byte8): Fix nbytes/nchars typo.

20675 (bidi_level_of_next_char): Don't try to lookup the cache for the
20676 next/previous character if nothing is cached there yet, or if we
20677 were just reseat()'ed to a new position.
20679 * xdisp.c (set_cursor_from_row): Set start and stop points
20680 according to the row's direction when priming the loop that looks
20681 for the glyph on which to display cursor.

20683 (display_prop_intangible_p): Reimplement to call
20684 handle_display_spec instead of single_display_spec_intangible_p.

20695 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20696 value of a `display' property is a "replacing spec".
20697 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20698 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20699 the display property, but just return a value indicating whether
20700 the display property will replace the characters it covers.
20701 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20702 frame_window_p members of struct bidi_it.

20728 * gnutls.c: Use Emacs's memory allocators.
20729 Without this change, the gnutls library would invoke malloc etc.
20730 directly, which causes problems on non-SYNC_INPUT hosts, and which
20731 runs afoul of improving memory_full behavior. (Bug#8761)
20732 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20733 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20734 xfree instead of the default malloc, realloc, free.
20735 (Fgnutls_boot): No need to check for memory allocation failure,
20736 since xmalloc does that for us.

20765 need to be updated by these changes.
20766 * fns.c (make_hash_table, maybe_resize_hash_table):
20767 Check for integer overflow with large hash tables.
20768 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20769 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20770 (SXHASH_REDUCE): New macro.
20771 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20772 Use it instead of discarding useful hash info with large hash values.
20773 (sxhash_float): New function.
20774 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20775 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20776 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20777 Rewrite to use FIXNUM_BITS, as this simplifies things.
20778 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20779 Adjust signatures to match updated version of code.
20780 (consing_since_gc): Now EMACS_INT, since a single hash table can
20781 use more than INT_MAX bytes.

20830 Make it possible to run ./temacs.
20832 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20833 syms_of_callproc does the same thing. Remove test for

20865 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20867 Minor fixes prompted by GCC 4.6.0 warnings.
20869 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20871 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20872 (x_clipboard_manager_save_all): Move extern decl to ...
20873 * xterm.h: ... here, so that it can be checked for consistency.
20875 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20877 * xselect.c (x_clipboard_manager_save_frame)
20878 (x_clipboard_manager_save_all): New functions.
20879 (Fx_clipboard_manager_save): Lisp function deleted.
20881 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20882 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20884 * xterm.h: Update prototype.
20886 2011-05-28 William Xu <william.xwl@gmail.com>
20888 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20889 exiting (Bug#8239).
20891 2011-05-28 Jim Meyering <meyering@redhat.com>
20893 Avoid a sign-extension bug in crypto_hash_function.
20894 * fns.c (to_uchar): Define.
20895 (crypto_hash_function): Use it to convert some newly-signed
20896 variables to unsigned, to avoid sign-extension bugs. For example,
20897 without this change, (md5 "truc") would evaluate to
20898 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20899 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20900 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20902 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20904 Integer overflow fixes.
20906 * dbusbind.c: Serial number integer overflow fixes.
20907 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20908 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20909 to hold a serial number that is too large for a fixnum.
20910 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20911 Check for serial numbers out of range. Decode any serial number
20912 that was so large that it became a float. (Bug#8722)
20914 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20915 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20916 Use XFASTINT rather than XUINT when numbers are nonnegative.
20917 (xd_append_arg, Fdbus_method_return_internal):
20918 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20919 arguments, check that Lisp number is nonnegative, rather than
20920 silently wrapping negative numbers around. (Bug#8722)
20921 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20924 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20926 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20928 ccl: Add integer overflow checks.
20929 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20930 (IN_INT_RANGE): New macros.
20931 (ccl_driver): Use them to check for integer overflow when
20932 decoding a CCL program. Many of the new checks are whether XINT (x)
20933 fits in int; it doesn't always, on 64-bit hosts. The new version
20934 doesn't catch all possible integer overflows, but it's an
20935 improvement. (Bug#8719)
20937 * alloc.c (make_event_array): Use XINT, not XUINT.
20938 There's no need for unsigned here.
20940 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20941 This follows up to the 2011-05-06 change that substituted uintptr_t
20942 for EMACS_INT. This case wasn't caught back then.
20944 Rework Fformat to avoid integer overflow issues.
20945 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20946 now (part of C89). Include <verify.h>.
20947 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20948 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20949 (Fformat): Avoid the prepass trying to compute sizes; it was only
20950 approximate and thus did not catch overflow reliably. Instead, walk
20951 through the format just once, formatting and computing sizes as we go,
20952 checking for integer overflow at every step, and allocating a larger
20953 buffer as needed. Keep track separately whether the format is
20954 multibyte. Keep only the most-recently calculated precision, rather
20955 than them all. Record whether each argument has been converted to
20956 string. Use EMACS_INT, not int, for byte and char and arg counts.
20957 Support field widths and precisions larger than INT_MAX. Avoid
20958 sprintf's undefined behavior with conversion specifications such as %#d
20959 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20960 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20961 formatting out-of-range floating point numbers with int
20962 formats. (Bug#8668)
20964 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20966 * data.c: Avoid integer truncation in expressions involving floats.
20967 * data.c: Include <intprops.h>.
20968 (arith_driver): When there's an integer overflow in an expression
20969 involving floating point, convert the integers to floating point
20970 so that the resulting value does not suffer from catastrophic
20971 integer truncation. For example, on a 64-bit host (* 4
20972 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20973 Do not rely on undefined behavior after integer overflow.
20975 merge count_size_as_multibyte, parse_str_to_multibyte
20976 * character.c, character.h (count_size_as_multibyte):
20977 Rename from parse_str_to_multibyte; all uses changed.
20978 Check for integer overflow.
20979 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20980 since it's now a duplicate of the other. This is more of
20981 a character than a buffer op, so better that it's in character.c.
20982 * fns.c, print.c: Adjust to above changes.
20984 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20986 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20988 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20990 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20991 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20992 (x_clipboard_manager_save): Now static.
20993 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20995 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20996 (crypto_hash_function): Now static.
20997 Fix pointer signedness problems. Avoid unnecessary initializations.
20999 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21001 * termhooks.h (Vselection_alist): Make it terminal-local.
21003 * terminal.c (create_terminal): Initialize it.
21005 * xselect.c: Support for clipboard managers.
21006 (Vselection_alist): Move to termhooks.h as terminal-local var.
21007 (LOCAL_SELECTION): New macro.
21008 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21009 (symbol_to_x_atom): Remove gratuitous arg.
21010 (x_handle_selection_request, lisp_data_to_selection_data)
21011 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21012 (x_own_selection, x_get_local_selection, x_convert_selection):
21013 New arg, specifying work frame. Use terminal-local Vselection_alist.
21014 (some_frame_on_display): Delete unused function.
21015 (Fx_own_selection_internal, Fx_get_selection_internal)
21016 (Fx_disown_selection_internal, Fx_selection_owner_p)
21017 (Fx_selection_exists_p): New optional frame arg.
21018 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21019 (x_handle_selection_clear): Don't treat other terminals with the
21020 same keyboard specially. Use the terminal-local Vselection_alist.
21021 (x_clear_frame_selections): Use Frun_hook_with_args.
21023 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21025 * xterm.h: Add support for those atoms.
21027 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21029 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21030 (converted_selections, conversion_fail_tag): New global variables.
21031 (x_selection_request_lisp_error): Free the above.
21032 (x_get_local_selection): Remove unnecessary code.
21033 (x_reply_selection_request): Args changed; handle arbitrary array
21034 of converted selections stored in converted_selections.
21035 Separate the XChangeProperty and SelectionNotify steps.
21036 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21037 (x_convert_selection): New function.
21038 (x_handle_selection_event): Simplify.
21039 (x_get_foreign_selection): Don't ignore incoming requests while
21040 waiting for an answer; this will fail when we implement
21041 SAVE_TARGETS, and seems unnecessary anyway.
21042 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21043 (Vx_sent_selection_functions): Doc fix.
21045 2011-05-26 Leo Liu <sdl.web@gmail.com>
21047 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21049 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21051 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21053 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21054 for fringe update if it has periodic bitmap.
21055 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21056 and fringe_bitmap_periodic_p.
21058 * fringe.c (get_fringe_bitmap_data): New function.
21059 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21060 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21061 row. Mark glyph row for fringe update if periodicity changed.
21063 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21064 for fringe update unless it has periodic bitmap.
21066 2011-05-25 Kenichi Handa <handa@m17n.org>
21068 * xdisp.c (get_next_display_element): Set correct it->face_id for
21069 a static composition.
21071 2011-05-24 Leo Liu <sdl.web@gmail.com>
21074 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21076 * fns.c (crypto_hash_function, Fsha1): New function.
21077 (Fmd5): Use crypto_hash_function.
21078 (syms_of_fns): Add Ssha1.
21080 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21082 * gnutls.c: Remove unused macros.
21083 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21084 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21085 Remove macros that are defined and never used.
21086 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21088 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21090 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21091 (Fx_get_selection_internal): Minor cleanup.
21092 (Fx_own_selection_internal): Rename arguments for consistency with
21095 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21097 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21099 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21101 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21103 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21105 * dispnew.c (scrolling_window): Don't exclude the case that the
21106 last enabled row in the desired matrix touches the bottom boundary.
21108 2011-05-21 Glenn Morris <rgm@gnu.org>
21110 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21111 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21112 and add some more files.
21114 2011-05-20 Eli Zaretskii <eliz@gnu.org>
21116 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21117 report_file_error introduced by the change from 2011-05-07.
21119 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21121 * systime.h (Time): Define only if emacs is defined.
21122 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21123 where the include path doesn't have X11/X.h by default. See
21124 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21126 2011-05-20 Kenichi Handa <handa@m17n.org>
21128 * composite.c (find_automatic_composition): Fix previous change.
21130 2011-05-20 Glenn Morris <rgm@gnu.org>
21132 * lisp.mk: New file, split from Makefile.in.
21133 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21134 (shortlisp): Remove.
21135 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21137 2011-05-19 Glenn Morris <rgm@gnu.org>
21139 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21140 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21141 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21142 (lisp): Set the order to that of loadup.el.
21143 (shortlisp): Make it a copy of $lisp.
21144 (SOME_MACHINE_LISP): Remove.
21145 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21146 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21148 2011-05-18 Kenichi Handa <handa@m17n.org>
21150 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21151 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21152 (find_automatic_composition): Mostly rewrite for efficiency.
21154 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21156 * makefile.w32-in: Update dependencies.
21158 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21160 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21161 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21163 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21165 Fix some integer overflow issues, such as string length overflow.
21167 * insdel.c (count_size_as_multibyte): Check for string overflow.
21169 * character.c (lisp_string_width): Check for string overflow.
21170 Use EMACS_INT, not int, for string indexes and lengths; in
21171 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21172 the resulting string length overflows an EMACS_INT; instead,
21173 report a string overflow if no precision given. When checking for
21174 precision exhaustion, use a check that cannot possibly have
21175 integer overflow. (Bug#8675)
21176 * character.h (lisp_string_width): Adjust to new signature.
21178 * alloc.c (string_overflow): New function.
21179 (Fmake_string): Use it. This doesn't change behavior, but saves
21180 a few bytes and will simplify future changes.
21181 * character.c (string_escape_byte8): Likewise.
21182 * lisp.h (string_overflow): New decl.
21184 Fixups, following up to the user-interface timestamp change.
21185 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21186 for UI timestamps, instead of unsigned long.
21187 * msdos.c (mouse_get_pos): Likewise.
21188 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21189 * w32gui.h (Time): Define by including "systime.h" rather than by
21190 declaring it ourselves. (Bug#8664)
21192 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21193 * image.c (clear_image_cache): Likewise.
21195 * term.c (term_mouse_position): Don't assume time_t wraparound.
21197 Be more systematic about user-interface timestamps.
21198 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21199 and sometimes 'EMACS_UINT', to represent these timestamps.
21200 This change causes it to use 'Time' uniformly, as that's what X uses.
21201 This makes the code easier to follow, and makes it easier to catch
21202 integer overflow bugs such as Bug#8664.
21203 * frame.c (Fmouse_position, Fmouse_pixel_position):
21204 Use Time, not unsigned long, for user-interface timestamps.
21205 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21206 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21207 * keyboard.h (last_event_timestamp): Likewise.
21208 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21209 * menu.h (xmenu_show): Likewise.
21210 * term.c (term_mouse_position): Likewise.
21211 * termhooks.h (struct input_event.timestamp): Likewise.
21212 (struct terminal.mouse_position_hook): Likewise.
21213 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21214 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21215 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21216 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21217 what it was before.
21218 * menu.h, termhooks.h: Include "systime.h", for Time.
21220 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21221 Don't assume that the difference between two unsigned long values
21222 can fit into an integer. At this point, we know button_down_time
21223 <= event->timestamp, so the difference must be nonnegative, so
21224 there's no need to cast the result if double-click-time is
21225 nonnegative, as it should be; check that it's nonnegative, just in
21226 case. This bug is triggered when events are more than 2**31 ms
21227 apart (about 25 days). (Bug#8664)
21229 * xselect.c (last_event_timestamp): Remove duplicate decl.
21230 (x_own_selection): Remove needless cast to unsigned long.
21232 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21233 that always fit in int. Use a sentinel instead of a counter, to
21234 avoid a temp and to allay GCC's concerns about possible int overflow.
21235 * frame.h (struct frame): Use int for menu_bar_items_used
21236 instead of EMACS_INT, since it always fits in int.
21238 * menu.c (grow_menu_items): Check for int overflow.
21240 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21242 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21243 Before, the code was not consistent. These values cannot exceed
21244 2**31 - 1 so there's no need to make them unsigned.
21245 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21246 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21247 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21249 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21251 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21252 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21253 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21254 presumably because the widths might not match.
21256 * window.c (size_window): Avoid needless test at loop start.
21258 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21260 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21262 2011-05-12 Drew Adams <drew.adams@oracle.com>
21264 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21266 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21268 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21269 `width' to `bar_area_x' and `bar_area_width', respectively.
21270 (x_scroll_run): Take account of fringe background extension.
21272 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21273 Rename local vars `left' and `width' to `bar_area_x' and
21274 `bar_area_width', respectively.
21275 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21276 background extension.
21278 2011-05-10 Jim Meyering <meyering@redhat.com>
21280 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21282 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21284 * image.c (Finit_image_library): Return t for built-in image types,
21285 like pbm and xbm. (Bug#8640)
21287 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21289 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21291 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21293 * w32console.c (Fset_screen_color): Doc fix.
21294 (Fget_screen_color): New function.
21295 (syms_of_ntterm): Defsubr it.
21297 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21298 unlink the temporary file if Fcall_process didn't create it in the
21300 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21301 child process will be redirected to a file specified with `:file'.
21302 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21303 cue to call_process_cleanup not to close that handle.
21305 2011-05-07 Ben Key <bkey76@gmail.com>
21307 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21308 one of two shell specific rules, either bootstrap-temacs-CMD or
21309 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21310 to the previous implementation of the bootstrap-temacs rule.
21311 The bootstrap-temacs-CMD rule is similar to the previous
21312 implementation of the bootstrap-temacs rule except that it
21313 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21316 These changes, along with some changes to nt/configure.bat,
21317 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21318 earlier fix to add support for --cflags and --ldflags options
21319 that include quotes so that it works whether make uses cmd or
21322 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21324 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21325 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21327 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21328 a string. Handle both cases.
21329 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21330 (Fdbus_register_method): Use Qinvalid_function.
21332 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21334 * makefile.w32-in: Update dependencies.
21335 (LISP_H): Add inttypes.h and stdin.h.
21336 (PROCESS_H): Add unistd.h.
21338 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21340 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21341 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21343 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21345 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21347 * term.c (vfatal): Remove stray call to va_end.
21348 It's not needed and the C Standard doesn't allow it here anyway.
21350 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21351 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21353 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21356 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21358 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21360 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21362 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21364 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21366 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21367 * charset.c (Fdefine_charset_internal): Don't initialize
21368 charset.code_space[15]. The value was garbage, on hosts with
21369 32-bit int (Bug#8600).
21371 * lread.c (read_integer): Be more consistent with string-to-number.
21372 Use string_to_number to do the actual conversion; this avoids
21373 rounding errors and fixes some other screwups. Without this fix,
21374 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21375 (digit_to_number): Move earlier, for benefit of read_integer.
21376 Return -1 if the digit is out of range for the base, -2 if it is
21377 not a digit in any supported base. (Bug#8602)
21379 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21381 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21382 to match comment at start of function. This also removes a
21383 GCC warning about overflow in a 32+64-bit port.
21385 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21387 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21388 Reported by Stefan Monnier in
21389 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21390 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21391 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21393 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21394 (EMACS_UINTPTR): Likewise, with uintptr_t.
21396 * lisp.h: Prefer 64-bit EMACS_INT if available.
21397 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21398 on 32-bit hosts that have 64-bit int, so that they can access
21400 However, temporarily disable this change unless the temporary
21401 symbol WIDE_EMACS_INT is defined.
21403 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21405 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21406 This removes an assumption that EMACS_INT and long are the same
21407 width as pointers. The assumption is true for Emacs porting targets
21408 now, but we want to make other targets possible.
21409 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21410 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21411 In the rest of the code, change types of integers that hold casted
21412 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21413 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21414 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21415 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21416 No need to cast type when ORing.
21417 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21418 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21419 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21420 assume EMACS_INT is the same width as char *.
21421 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21422 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21423 Remove no-longer-needed casts.
21424 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21425 (xg_tool_bar_help_callback, xg_make_tool_item):
21426 Use EMACS_INTPTR to hold an integer
21427 that will be cast to void *; this can avoid a GCC warning
21428 if EMACS_INT is not the same width as void *.
21429 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21430 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21431 (current_message_1, set_message_1):
21432 Use a local to convert to proper width without a cast.
21433 * xmenu.c (dialog_selection_callback): Likewise.
21435 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21436 Also, don't assume VALBITS / RAND_BITS is less than 5,
21437 and don't rely on undefined behavior when shifting a 1 left into
21439 * lisp.h (get_random): Change signature to match.
21441 * lread.c (hash_string): Use size_t, not int, for hash computation.
21442 Normally we prefer signed values; but hashing is special, because
21443 it's better to use unsigned division on hash table sizes so that
21444 the remainder is nonnegative. Also, size_t is the natural width
21445 for hashing into memory. The previous code used 'int', which doesn't
21446 retain enough info to hash well into very large tables.
21447 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21449 * dbusbind.c: Don't possibly lose pointer info when converting.
21450 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21451 Use XPNTR rather than XHASH, so that the high-order bits of
21452 the pointer aren't lost when converting through void *.
21454 * eval.c (Fautoload): Don't double-shift a pointer.
21456 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21458 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21460 * gnutls.c (DEF_GNUTLS_FN):
21461 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21463 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21465 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21468 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21470 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21471 New version that can reserve upto 2GB of heap space.
21473 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21475 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21477 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21479 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21480 `gnutls_certificate_set_x509_key_file'.
21482 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21484 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21485 Update dependencies.
21487 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21489 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21490 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21491 Remove unused parameter `fildes'.
21492 * process.c (read_process_output, send_process): Don't pass it.
21494 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21496 Fix previous change: the library cache is defined in w32.c.
21497 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21498 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21500 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21502 Implement dynamic loading of GnuTLS on Windows.
21504 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21505 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21506 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21509 * gnutls.c (Qgnutls_dll): Define.
21510 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21511 (gnutls_*): Declare function pointers.
21512 (init_gnutls_functions): New function to initialize function pointers.

21514 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21515 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21516 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21517 (emacs_gnutls_write, emacs_gnutls_read)
21518 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21519 (Fgnutls_available_p): New function.
21520 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21521 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21522 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21524 * image.c: Include w32.h.
21525 (Vimage_type_cache): Delete.

21527 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21528 (w32_delayed_load): Move to w32.c.
21530 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21532 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21533 (w32_delayed_load): Move from image.c. When loading a library, record
21534 its filename in the :loaded-from property of the library id.
21535 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21536 Initialize and staticpro them.
21537 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21539 * process.c: Include lisp.h before w32.h, not after.
21540 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21541 instead of gnutls_record_check_pending.
21543 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21545 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21547 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21548 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21551 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21553 * xterm.c (x_set_frame_alpha): Do not set property on anything
21554 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21556 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21558 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21560 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21562 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

21570 (Qgnutls_bootprop_callbacks_verify): Make static.
21572 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21574 * callproc.c: Indentation fixup.
21576 * sysdep.c (wait_for_termination_1): Make static.
21577 (wait_for_termination, interruptible_wait_for_termination):
21578 Move after wait_for_termination_1.
21580 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21582 * sysdep.c (interruptible_wait_for_termination): New function
21583 which is like wait_for_termination, but allows keyboard
21586 * callproc.c (Fcall_process): Add (:file "file") as an option for
21588 (Fcall_process_region): Ditto.
21590 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21592 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21593 rather than `XVECTOR (FOO)->size'.
21595 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21596 inttypes.h, as a gnulib replacement is used if it not available in
21599 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21601 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21602 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21603 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21605 * coding.c (coding_alloc_by_realloc): Error out if destination
21606 will grow beyond MOST_POSITIVE_FIXNUM.
21607 (decode_coding_emacs_mule): Abort if there isn't enough place in
21608 charbuf for the composition carryover bytes. Reserve an extra
21609 space for up to 2 characters produced in a loop.
21610 (decode_coding_iso_2022): Abort if there isn't enough place in
21611 charbuf for the composition carryover bytes.
21613 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21615 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21616 aborting when %lld or %lll format is passed.
21617 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21618 %llo or %llx format is passed. (Bug#8545)
21620 * window.c (window_scroll_line_based): Use a marker instead of
21621 simple variables to record original value of point. (Bug#7952)
21623 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21624 produced by %s or %c overflows available buffer space. (Bug#8545)
21626 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21628 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21629 (SIZE_MAX): Move defn after all includes, as they might #define it.
21631 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21633 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21635 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21637 * keyboard.c (Qdelayed_warnings_hook): Define.
21638 (command_loop_1): Run `delayed-warnings-hook'
21639 if Vdelayed_warnings_list is non-nil.
21640 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21641 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21643 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21645 * doprnt.c (doprnt): Don't return value smaller than the buffer
21646 size if the message was truncated. (Bug#8545).
21648 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21650 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

21653 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21655 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21657 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21659 * makefile.w32-in: Update dependencies.
21661 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21663 Improve `doprnt' and its usage. (Bug#8545)
21664 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21665 `format_end'. Remove support for %l as a conversion specifier.
21666 Don't use xrealloc. Improve diagnostics when the %l size modifier
21667 is used. Update the commentary.
21669 * eval.c (verror): Simplify calculation of size_t.
21671 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21674 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21676 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21679 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21681 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21682 This makes this file independent of the recent pseudovector change.
21684 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21686 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21688 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21689 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21690 Remove unused local.
21691 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21693 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21694 GCC 4.6.0 optimizes based on type-based alias analysis.
21695 For example, if b is of type struct buffer * and v of type struct
21696 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21697 != &v->size, and therefore "v->size = 1; b->size = 2; return
21698 v->size;" must therefore return 1. This assumption is incorrect
21699 for Emacs, since it type-puns struct Lisp_Vector * with many other
21700 types. To fix this problem, this patch adds a new type struct
21701 vectorlike_header that documents the constraints on layout of vectors
21702 and pseudovectors, and helps optimizing compilers not get fooled
21703 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21704 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21705 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21707 (XSETPVECTYPE): Rewrite in terms of new macro.
21708 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21709 This is a bit clearer, and further avoids the possibility of
21710 undesirable aliasing.
21711 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21712 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21713 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21714 since Lisp_Subr is a special case (no "next" field).
21715 (ASIZE): Now uses header.size rather than size.
21716 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21717 to avoid the hassle of writing XVECTOR (foo)->header.size.
21718 (struct vectorlike_header): New type.
21719 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21720 object, to help avoid aliasing.
21721 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21722 (SUBRP): Likewise, since Lisp_Subr is a special case.
21723 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21724 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21725 (struct Lisp_Hash_Table): Combine first two members into a single
21726 struct vectorlike_header member. All uses of "size" and "next" members
21727 changed to be "header.size" and "header.next".
21728 * buffer.h (struct buffer): Likewise.
21729 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21730 * frame.h (struct frame): Likewise.
21731 * process.h (struct Lisp_Process): Likewise.
21732 * termhooks.h (struct terminal): Likewise.
21733 * window.c (struct save_window_data, struct saved_window): Likewise.
21734 * window.h (struct window): Likewise.
21735 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21736 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21737 * buffer.c (init_buffer_once): Likewise.
21738 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21740 * process.c (Fformat_network_address): Use local var for size,
21743 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21745 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21746 * data.c (atof): Remove decl; no longer used or needed.
21747 (digit_to_number): Move to lread.c.
21748 (Fstring_to_number): Use new string_to_number function, to be
21749 consistent with how the Lisp reader treats infinities and NaNs.
21750 Do not assume that floating-point numbers represent EMACS_INT
21751 without losing information; this is not true on most 64-bit hosts.
21752 Avoid double-rounding errors, by insisting on integers when
21753 parsing non-base-10 numbers, as the documentation specifies.
21754 * lisp.h (string_to_number): New decl, replacing ...
21755 (isfloat_string): Remove.
21756 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21757 (read1): Do not accept +. and -. as integers; this
21758 appears to have been a coding error. Similarly, do not accept
21759 strings like +-1e0 as floating point numbers. Do not report
21760 overflow for integer overflows unless the base is not 10 which
21761 means we have no simple and reliable way to continue.
21762 Break out the floating-point parsing into a new
21763 function string_to_number, so that Fstring_to_number parses
21764 floating point numbers consistently with the Lisp reader.
21765 (digit_to_number): Move here from data.c. Make it static inline.
21766 (E_CHAR, EXP_INT): Remove, replacing with ...
21767 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21768 (string_to_number): New function, replacing isfloat_string.
21769 This function checks for valid syntax and produces the resulting
21770 Lisp float number too. Rework it so that string-to-number
21771 no longer mishandles examples like "1.0e+". Use strtoumax,
21772 so that overflow for non-base-10 numbers is reported only when
21773 there's no portable and simple way to convert to floating point.
21775 * textprop.c (set_text_properties_1): Rewrite for clarity,
21776 and to avoid GCC warning about integer overflow.
21778 * intervals.h (struct interval): Use EMACS_INT for members
21779 where EMACS_UINT might cause problems. See
21780 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21781 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21782 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21784 (offset_intervals): Tell GCC not to worry about length overflow
21785 when negating a negative length.
21787 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21788 (overrun_check_free): Likewise.
21790 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21791 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21794 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21795 (gnutls_make_error): Rename local to avoid shadowing.
21796 (gnutls_emacs_global_deinit): ifdef out; not used.
21797 (Fgnutls_boot): Use const for pointer to readonly storage.
21798 Comment out unused local. Fix pointer signedness problems.
21800 * lread.c (openp): Don't stuff size_t into an 'int'.
21801 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21802 about possible signed overflow.
21804 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21805 (GDK_KEY_g): Don't define if already defined.
21806 (xg_prepare_tooltip): Avoid pointer signedness problem.
21807 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21809 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21810 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21812 * xfns.c (Fx_window_property): Simplify a bit,
21813 to make a bit faster and to avoid GCC 4.6.0 warning.
21814 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21816 * fns.c (internal_equal): Don't assume size_t fits in int.
21818 * alloc.c (compact_small_strings): Tighten assertion a little.
21820 Replace pEd with more-general pI, and fix some printf arg casts.
21821 * lisp.h (pI): New macro, generalizing old pEd macro to other
21822 conversion specifiers. For example, use "...%"pI"d..." rather
21823 than "...%"pEd"...".
21824 (pEd): Remove. All uses replaced with similar uses of pI.
21825 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21826 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21827 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21828 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21829 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21830 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21831 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21833 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21834 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21835 * print.c (safe_debug_print, print_object): Likewise.
21836 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21838 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21839 avoiding the 0 flag, which is not portable.
21840 * process.c (Fmake_network_process): Use pI to avoid cast.
21841 * region-cache.c (pp_cache): Likewise.
21842 * xdisp.c (decode_mode_spec): Likewise.
21843 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21844 behavior on 64-bit hosts with printf arg.
21845 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21846 (x_stop_queuing_selection_requests): Likewise.
21847 (x_get_window_property): Don't truncate byte count to an 'int'
21850 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21851 here, since it parses constructs like leading '-' and spaces,
21852 which are not wanted; and it overflows with large numbers.
21853 Instead, simply match F[0-9]+, which is what is wanted anyway.
21855 * alloc.c: Remove unportable assumptions about struct layout.
21856 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21857 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21858 (allocate_vectorlike, make_pure_vector): Use the new macros,
21859 plus offsetof, to remove unportable assumptions about struct layout.
21860 These assumptions hold on all porting targets that I know of, but
21861 they are not guaranteed, they're easy to remove, and removing them
21862 makes further changes easier.
21864 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21865 This doesn't fix a bug but makes the code clearer.
21866 (string_overrun_cookie): Now const. Use initializers that
21867 don't formally overflow signed char, to avoid warnings.
21868 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21869 can cause Emacs to crash when string overrun checking is enabled.
21870 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21871 multiple of sizeof (EMACS_INT); it need not be, if
21872 alignof(EMACS_INT) < sizeof (EMACS_INT).
21873 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21875 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21882 supposed to be handshaking. (Bug#8556)
21883 Reported by Paul Eggert <eggert@cs.ucla.edu>.

21902 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21904 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21905 "cast to pointer from integer of different size".
21907 Improve doprnt and its use in verror. (Bug#8545)
21908 * doprnt.c (doprnt): Document the set of format control sequences
21909 supported by the function. Use SAFE_ALLOCA instead of always
21912 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21913 is one byte too soon. Don't use xrealloc; instead xfree and
21916 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21918 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21921 * gnutls.c: Renamed global_initialized to
21922 gnutls_global_initialized. Added internals for the
21923 :verify-hostname-error, :verify-error, and :verify-flags
21924 parameters of `gnutls-boot' and documented those parameters in the
21925 docstring. Start callback support.
21926 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21927 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21928 on error. Return error code.

21988 changes in globals.h immediately force recompilation.
21989 (TAGS): Depend on $(CURDIR)/m/intel386.h and
21990 $(CURDIR)/s/ms-w32.h.

22000 * doprnt.c: Include limits.h.
22001 (SIZE_MAX): New macro.
22002 (doprnt): Return a size_t value. 2nd arg is now size_t.
22003 Many local variables are now size_t instead of int or unsigned.
22004 Improve overflow protection. Support `l' modifier for integer
22005 conversions. Support %l conversion. Don't assume an EMACS_INT
22006 argument for integer conversions and for %c.
22008 * lisp.h (doprnt): Restore prototype.
22010 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22011 $(SRC)/character.h.
22013 * Makefile.in (base_obj): Add back doprnt.o.
22015 * deps.mk (doprnt.o): Add back prerequisites.
22016 (callint.o): Depend on character.h.
22018 * eval.c (internal_lisp_condition_case): Include the handler
22019 representation in the error message.

22025 * callint.c (Fcall_interactively): When displaying error message
22026 about invalid control letter, pass the character's codepoint, not
22027 a pointer to its multibyte form. Improve display of the character
22028 in octal and display also its hex code.
22030 * character.c (char_string): Use %x to display the (unsigned)
22031 codepoint of an invalid character, to avoid displaying a bogus
22034 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
22035 `error', not SYMBOL_NAME itself.
22037 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
22038 character arguments to `error'.
22040 * charset.c (check_iso_charset_parameter): Fix incorrect argument
22041 to `error' in error message about FINAL_CHAR argument. Make sure
22042 FINAL_CHAR is a character, and use %c when it is passed as

22107 Define only if needed.
22109 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
22110 by pacifying GCC about it. Maybe it's time to retire it?
22111 * xfaces.c (USG, __TIMEVAL__): Likewise.
22113 * dispextern.h (struct redisplay_interface): Rename param
22114 to avoid shadowing.
22115 * termhooks.h (struct terminal): Likewise.
22116 * xterm.c (xembed_send_message): Likewise.
22118 * insdel.c (make_gap_smaller): Define only if
22119 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
22121 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
22124 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
22125 so that we aren't warned about unused symbols.
22127 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
22129 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

22138 define if USE_GTK || USE_X_TOOLKIT.
22139 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
22140 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

22142 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
22144 * xmenu.c (menu_help_callback): Pointer type fixes.
22145 Use const pointers when pointing at readonly data. Avoid pointer

22162 compatible char. Avoid the old compiler warnings about
22163 out-of-range initializers by using, for example, '\xab' rather
22166 * xgselect.c (xgselect_initialize): Check vs interface
22167 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

22232 * nsfont.m: Fixed bugs in ns_get_family and
22233 ns_descriptor_to_entity that were caused by using free to

22236 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
22237 --enable-checking=xmallocoverrun). xfree is now used to
22238 deallocate these memory blocks.

22618 (n_float_blocks, float_free_list, cons_block, cons_block_index):
22619 (cons_free_list, last_marked_index):
22621 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
22622 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22623 (mark_backtrace): Define only if BYTE_MARK_STACK.
22624 * xdisp.c (message_enable_multibyte): Now static.
22626 Declare Lisp_Object Q* variables to be 'static' if not exported.
22627 This makes it easier for human readers (and static analyzers)
22628 to see whether these variables are used from other modules.
22629 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22630 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
22631 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
22632 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
22633 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
22634 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
22635 * xmenu.c, xselect.c:
22636 Declare Q* vars static if they are not used in other modules.
22637 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
22638 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
22639 Remove decls of unexported vars.
22640 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22642 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22644 Make Emacs functions such as Fatom 'static' by default.
22645 This makes it easier for human readers (and static analyzers)
22646 to see whether these functions can be called from other modules.
22647 DEFUN now defines a static function. To make the function external
22648 so that it can be used in other C modules, use the new macro DEFUE.
22649 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22650 (Finit_image_library):
22651 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22652 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22653 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22654 Remove decls, since these functions are now static.
22655 (Funintern, Fget_internal_run_time): New decls, since these functions
22656 were already external.
22658 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22659 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
22660 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

22663 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
22664 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
22665 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22666 Mark functions with DEFUE instead of DEFUN,
22667 if they are used in other modules.
22668 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22669 decls for now-static functions.
22670 * buffer.h (Fdelete_overlay): Remove decl.
22671 * callproc.c (Fgetenv_internal): Mark as internal.
22672 * composite.c (Fremove_list_of_text_properties): Remove decl.

22676 * doc.c (Fdocumntation_property): New forward static decl.
22677 * eval.c (Ffetch_bytecode): New forward static decl.
22678 (Funintern): Remove extern decl; now in .h file where it belongs.
22679 * fileio.c (Fmake_symbolic_link): New forward static decl.
22680 * image.c (Finit_image_library): New forward static decl.
22681 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22682 * intervals.h (Fprevious_property_change):
22683 (Fremove_list_of_text_properties): Remove decls.
22684 * keyboard.c (Fthis_command_keys): Remove decl.
22685 (Fcommand_execute): New forward static decl.
22686 * keymap.c (Flookup_key): New forward static decl.
22687 (Fcopy_keymap): Now static.
22688 * keymap.h (Flookup_key): Remove decl.
22689 * process.c (Fget_process): New forward static decl.
22690 (Fprocess_datagram_address): Mark as internal.

22701 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22703 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22706 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22708 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22709 when at ZV. (Bug#8487)
22711 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22713 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22715 * keyboard.c (parse_tool_bar_item): Likewise.
22716 * sound.c (sound_cleanup, alsa_close): Likewise.
22717 * termcap.c (tgetent): Likewise.
22718 * xfns.c (x_default_font_parameter): Likewise.
22719 * xsettings.c (read_and_apply_settings): Likewise.
22721 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22722 (overrun_check_free): Protoize.
22724 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22726 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22727 since callers should never pass a negative size.
22728 Change the signature to match that of plain 'read' and 'write'; see
22729 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22730 * lisp.h: Update prototypes of emacs_write and emacs_read.
22732 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22734 * xdisp.c (redisplay_window): Don't try to determine the character
22735 position of the scroll margin if the window start point w->startp
22736 is outside the buffer's accessible region. (Bug#8468)
22738 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22740 Fix write-region and its subroutines for buffers > 2GB.
22741 * fileio.c (a_write, e_write): Modify declaration of arguments and
22742 local variables to support buffers larger than 2GB.
22743 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22745 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22746 argument, local variables, and return value.
22748 * lisp.h: Update prototypes of emacs_write and emacs_read.
22750 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22752 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22754 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22756 Fix more problems found by GCC 4.6.0's static checks.
22758 * xdisp.c (vmessage): Use a better test for character truncation.
22760 * charset.c (load_charset_map): <, not <=, for optimization,
22761 and to avoid potential problems with integer overflow.
22762 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22763 * casetab.c (set_identity, shuffle): Likewise.
22764 * editfns.c (Fformat): Likewise.
22765 * syntax.c (skip_chars): Likewise.
22767 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22768 This also lets GCC 4.6.0 generate slightly better loop code.
22770 * callint.c (Fcall_interactively): <, not <=, for optimization.
22771 (Fcall_interactively): Count the number of arguments produced,
22772 not the number of arguments given. This is simpler and lets GCC
22773 4.6.0 generate slightly better code.
22775 * ftfont.c: Distingish more carefully between FcChar8 and char.
22776 The previous code passed unsigned char * to a functions like
22777 strlen and xstrcasecmp that expect char *, which does not
22778 conform to the C standard.
22779 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22780 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22781 char * when the C standard requires it.
22783 * keyboard.c (read_char): Remove unused var.
22785 * eval.c: Port to Windows vsnprintf (Bug#8435).
22786 Include <limits.h>.
22787 (SIZE_MAX): Define if the headers do not.
22788 (verror): Do not give up if vsnprintf returns a negative count.
22789 Instead, grow the buffer. This ports to Windows vsnprintf, which
22790 does not conform to C99. Problem reported by Eli Zaretskii.
22791 Also, simplify the allocation scheme, by avoiding the need for
22792 calling realloc, and removing the ALLOCATED variable.
22794 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22796 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22797 But keep the doprint source code for now, as we might revamp it
22798 and use it again (Bug#8435).
22799 * lisp.h (doprnt): Remove.
22800 * Makefile.in (base_obj): Remove doprnt.o.
22801 * deps.mk (doprnt.o): Remove.
22803 error: Print 32- and 64-bit integers portably (Bug#8435).
22804 Without this change, on typical 64-bit hosts error ("...%d...", N)
22805 was used to print both 32- and 64-bit integers N, which relied on
22806 undefined behavior.
22807 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22808 * lisp.h (error, verror): Mark as printf-like functions.
22809 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22810 Report overflow in size calculations when allocating printf buffer.
22811 Do not truncate output string at its first null byte.
22812 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22813 Truncate the output at a character boundary, since vsnprintf does not
22815 * charset.c (check_iso_charset_parameter): Convert internal
22816 character to string before calling 'error', since %c now has the
22818 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22819 overflow when computing char to be passed to 'error'. Do not
22820 pass Lisp_Object to 'error'; pass the integer instead.
22821 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22822 formatted with plain %d.
22824 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22826 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22828 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22830 * xterm.c (x_catch_errors): Remove duplicate declaration.
22832 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22834 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22836 2011-04-10 Jim Meyering <meyering@redhat.com>
22838 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22839 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22840 return ssize_t not "int", and use size_t as the buffer length.
22841 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22842 * gnutls.h: Update declarations.
22843 * process.c (read_process_output): Use ssize_t, to match.
22844 (send_process): Likewise.
22846 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22848 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22850 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22852 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22853 Use unsigned char, to match FcChar8 type definition.
22855 * xterm.c (handle_one_xevent):
22856 * xmenu.c (create_and_show_popup_menu):
22857 * xselect.c (x_decline_selection_request)
22858 (x_reply_selection_request): Avoid type-punned deref of X events.
22860 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22862 Fix some uses of `int' instead of EMACS_INT.
22863 * search.c (string_match_1, fast_string_match)
22864 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22865 (scan_buffer, find_next_newline_no_quit)
22866 (find_before_next_newline, search_command, Freplace_match)
22867 (Fmatch_data): Make some `int' variables be EMACS_INT.
22869 * xdisp.c (display_count_lines): 3rd argument and return value now
22870 EMACS_INT. All callers changed.
22871 (pint2hrstr): Last argument is now EMACS_INT.
22873 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22874 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22875 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22876 (decode_coding_utf_16, decode_coding_emacs_mule)
22877 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22878 (decode_coding_ccl, decode_coding_charset)
22879 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22880 (decode_coding_iso_2022, decode_coding_emacs_mule)
22881 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22882 <char_offset, last_offset>: Declare EMACS_INT.
22883 (encode_coding_utf_8, encode_coding_utf_16)
22884 (encode_coding_emacs_mule, encode_invocation_designation)
22885 (encode_designation_at_bol, encode_coding_iso_2022)
22886 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22887 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22889 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22890 (encode_invocation_designation): Last argument P_NCHARS is now
22892 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22893 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22895 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22898 * ccl.c (Fccl_execute_on_string): Declare some variables
22901 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22903 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22905 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22907 * process.c (Fformat_network_address): Doc fix.
22909 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22911 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22913 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22915 * keyboard.c (read_char): Call Lisp function help-form-show,
22916 instead of using internal_with_output_to_temp_buffer.
22917 (Qhelp_form_show): New var.
22918 (syms_of_keyboard): Use DEFSYM macro.
22920 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22924 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22926 * process.c (Flist_processes): Remove to Lisp.
22927 (list_processes_1): Delete.
22929 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22931 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22933 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22935 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22937 Fix more problems found by GCC 4.6.0's static checks.
22939 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22941 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22943 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22945 * xdisp.c (vmessage): Mark as a printf-like function.
22947 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22949 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22951 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22952 printf-like functions.

22954 to system-supplied API.
22956 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22958 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22959 This avoids several warnings with gcc -Wstrict-overflow.
22960 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22961 directly, rather than having caller test rule sign. This avoids
22962 some unnecessary tests.
22963 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22964 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22965 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22967 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22968 (xfont_open): Avoid unnecessary tests.
22970 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22972 * composite.h, composite.c (composition_gstring_put_cache):
22973 Use EMACS_INT, not int, for length.
22975 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22976 breaking out part of COMPOSITION_DECODE_RULE.
22977 (COMPOSITION_DECODE_RULE): Use it.
22978 * composite.c (get_composition_id): Remove unused local vars,
22979 by using the new macro.
22981 * textprop.c (set_text_properties_1): Change while to do-while,
22982 since the condition is always true at first.
22984 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22985 (interval_deletion_adjustment): Return unsigned value.
22988 * process.c (list_processes_1, create_pty, read_process_output):
22989 (exec_sentinel): Remove vars that were set but not used.
22990 (create_pty): Remove unnecessary "volatile"s.
22991 (Fnetwork_interface_info): Avoid possibility of int overflow.

22993 (read_process_output): Simplify nbytes computation if buffered.
22995 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
22997 * syntax.c (scan_words): Remove var that was set but not used.
22998 (update_syntax_table): Use unsigned instead of int.
23000 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
23001 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
23002 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
23004 * print.c (print_error_message): Avoid int overflow.
23006 * font.c (font_list_entities): Redo for clarity,
23007 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23009 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23010 (font_score): Avoid potential overflow in diff calculation.
23012 * fns.c (substring_both): Remove var that is set but not used.
23013 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23015 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23017 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23018 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23019 can always succeed if overflow has undefined behavior.
23021 * search.c (boyer_moore, wordify): Remove vars set but not used.
23022 (wordify): Omit three unnecessary tests.
23024 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23025 All callers changed. This avoids the need for an unused var.
23027 * casefiddle.c (casify_region): Remove var that is set but not used.
23029 * dired.c (file_name_completion): Remove var that is set but not used.
23031 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23033 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23034 (Finsert_file_contents): Remove unnecessary code checking fd.
23036 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23037 Check for integer overflow on size calculations.
23039 * buffer.c (Fprevious_overlay_change): Remove var that is set
23042 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23043 Remove vars that are set but not used.
23044 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23045 (timer_check_2): Mark vars as initialized.
23047 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23049 * image.c (lookup_image): Remove var that is set but not used.
23050 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23052 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23053 that are set but not used.
23055 * xfns.c (make_invisible_cursor): Don't return garbage
23056 if XCreateBitmapFromData fails (Bug#8410).
23058 * xselect.c (x_get_local_selection, x_handle_property_notify):
23059 Remove vars that are set but not used.
23061 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

23065 Remove var that is set but not used.
23066 (scroll_bar_windows_size): Now size_t, not int.
23067 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23068 Check for overflow.
23070 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23071 (map_tty_color) [!defined MSDOS]: Likewise.
23073 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23075 * coding.c: Remove vars that are set but not used.
23076 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

23083 that is set but not used.
23085 * print.c (print_object): Remove var that is set but not used.
23087 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23088 The gnulib version avoids calling malloc in the usual case,
23089 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23090 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23091 * filelock.c (current_lock_owner): Likewise.
23092 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23093 * sysdep.c: Include allocator.h, careadlinkat.h.
23094 (emacs_no_realloc_allocator): New static constant.
23095 (emacs_readlink): New function.
23096 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23097 ../lib/careadlinkat.h.
23099 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23101 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

23123 do not dereference NULL upon failed strdup
23124 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23125 (ns_get_family): Likewise.
23127 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23129 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23131 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23133 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23136 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23138 Add lexical binding.
23140 * window.c (Ftemp_output_buffer_show): New fun.

23149 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23151 (syms_of_lread): Declare `lexical-binding'.
23153 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23155 * keyboard.c (eval_dyn): New fun.
23156 (menu_item_eval_property): Use it.
23158 * image.c (parse_image_spec): Use Ffunctionp.
23160 * fns.c (concat, mapcar1): Accept byte-code-functions.
23162 * eval.c (Fsetq): Handle lexical vars.
23163 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23164 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23165 (FletX, Flet): Obey lexical binding.
23166 (Fcommandp): Handle closures.
23167 (Feval): New `lexical' arg.
23168 (eval_sub): New function extracted from Feval. Use it almost
23169 everywhere where Feval was used. Look up vars in lexical env.
23171 (Ffunctionp): Move from subr.el.
23172 (Ffuncall): Handle closures.
23173 (apply_lambda): Remove `eval_flags'.
23174 (funcall_lambda): Handle closures and new byte-code-functions.
23175 (Fspecial_variable_p): New function.
23176 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23177 but without exporting it to Lisp.
23179 * doc.c (Fdocumentation, store_function_docstring):
23180 * data.c (Finteractive_form): Handle closures.
23182 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23185 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23187 (exec_byte_code): New function extracted from Fbyte_code to handle new
23188 calling convention for byte-code-functions. Add new byte-codes.
23190 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23192 * alloc.c (Fmake_symbol): Init new `declared_special' field.

23196 * xdisp.c (redisplay_internal): Fix prototype.
23198 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23200 * xdisp.c (SCROLL_LIMIT): New macro.
23201 (try_scrolling): Use it when setting scroll_limit.
23202 Limit scrolling to 100 screen lines.
23203 (redisplay_window): Even when falling back on "recentering",
23204 position point in the window according to scroll-conservatively,
23205 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23207 (try_scrolling): When point is above the window, allow searching
23208 as far as scroll_max, or one screenful, to compute vertical
23209 distance from PT to the scroll margin position. This prevents
23210 try_scrolling from unnecessarily failing when
23211 scroll-conservatively is set to a value slightly larger than the
23212 window height. Clean up the case of PT below the margin at bottom
23213 of window: scroll_max can no longer be INT_MAX. When aggressive
23214 scrolling is in use, don't let point enter the opposite scroll
23215 margin as result of the scroll.
23216 (syms_of_xdisp) <scroll-conservatively>: Document the
23217 threshold of 100 lines for never-recentering scrolling.

23224 (message_log_check_duplicate): Remove parameters `prev_bol' and
23225 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23226 (redisplay_internal): Remove parameter `preserve_echo_area',
23227 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23229 * indent.c (Fvertical_motion):
23230 * window.c (window_scroll_pixel_based, Frecenter):
23231 Don't pass `need_y_p' to `move_it_by_lines'.
23233 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23235 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23236 steal a few bits to be more compact.
23237 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23238 Remove unneeded casts.
23240 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23242 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23244 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23245 binding" message (bug#7967).
23247 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23249 Fix more problems found by GCC 4.6.0's static checks.
23251 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23252 Remove unused local var.
23254 * editfns.c (Fmessage_box): Remove unused local var.
23256 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23257 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23258 Omit unused local vars.
23259 * window.c (shrink_windows): Omit unused local var.
23260 * menu.c (digest_single_submenu): Omit unused local var.
23261 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23262 Omit unused local var.
23264 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23265 Don't assume string length fits in int.
23266 (keyremap_step, read_key_sequence): Use size_t for sizes.

23270 instead of alloca (Bug#8344).
23272 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23273 (Fbacktrace_frame): Don't assume nframes fits in int.
23275 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

23282 * cm.c (calccost): Turn while-do into do-while, for clarity.
23284 * keyboard.c (syms_of_keyboard): Use the same style as later
23285 in this function when indexing through an array. This also
23286 works around GCC bug 48267.
23288 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23290 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23292 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23293 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23295 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23296 This avoids undefined behavior on integer overflow, and is a bit
23297 more convenient anyway since it is compared to a size_t variable.
23299 Variadic C functions now count arguments with size_t, not int.
23300 This avoids an unnecessary limitation on 64-bit machines, which
23301 caused (substring ...) to crash on large vectors (Bug#8344).

23311 * fns.c (concat): Likewise.
23312 * frame.c (x_set_frame_parameters): Likewise.
23313 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23314 0 if not found, not -1. All callers changed.
23316 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23317 (stack_copy_size): Now size_t, not int.
23318 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23320 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23322 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23323 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

23339 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23340 don't set the hook to nil, but remove the offending function instead.

23342 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23343 Vcommand_hook_internal.

23346 (funcall_nil, funcall_not): New functions.
23347 (run_hook_with_args): Call each function through a `funcall' argument.

23491 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
23492 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
23493 (Fx_close_connection): Remove unused variable `i'.
23495 * w32font.c (w32font_draw): Return number of glyphs.
23496 (w32font_open_internal): Remove unused variable `i'.
23497 (w32font_driver): Add missing initializer.

23511 2011-03-23 Julien Danjou <julien@danjou.info>
23513 * term.c (Fsuspend_tty, Fresume_tty):
23514 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
23515 * window.c (temp_output_buffer_show):
23516 * insdel.c (signal_before_change):
23517 * frame.c (Fhandle_switch_frame):
23518 * fileio.c (Fdo_auto_save):

23521 * cmds.c (internal_self_insert):
23522 * callint.c (Fcall_interactively):
23523 * buffer.c (Fkill_all_local_variables):
23524 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23526 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23527 unconditionally since it does the check itself.
23529 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23531 Fix more problems found by GCC 4.5.2's static checks.
23533 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23534 the first time through the loop, since we know p0 < p1 then.
23535 This also avoids a gcc -Wstrict-overflow warning.
23537 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23538 leading to a memory leak, possible in functions like
23539 load_charset_map_from_file that can allocate an unbounded number
23540 of objects (Bug#8318).
23542 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23543 that could (at least in theory) be that large.
23545 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23546 This is less likely to overflow, and avoids undefined behavior if
23547 overflow does occur. All callers changed. Use strtoul to scan
23548 for the unsigned long integer.
23549 (pint2hrstr): Simplify and tune code slightly.
23550 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23552 * scroll.c (do_scrolling): Work around GCC bug 48228.
23553 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
23555 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
23556 This also avoids a warning with gcc -Wstrict-overflow.
23557 (validate_x_resource_name): Simplify count usage.
23558 This also avoids a warning with gcc -Wstrict-overflow.
23560 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23563 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23565 * process.c (Fmake_network_process): Use socklen_t, not int,
23566 where POSIX says socklen_t is required in portable programs.
23567 This fixes a porting bug on hosts like 64-bit HP-UX, where
23568 socklen_t is wider than int (Bug#8277).
23569 (Fmake_network_process, server_accept_connection):
23570 (wait_reading_process_output, read_process_output):
23573 * process.c: Rename or move locals to avoid shadowing.

23575 (read_process_output_error_handler, exec_sentinel_error_handler):
23576 Rename or move locals.

23580 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
23581 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
23583 Make tparam.h and terminfo.c consistent.
23584 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23585 Include tparam.h instead, since it declares them.
23586 * cm.h (PC): Remove extern decl; tparam.h now does this.
23587 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23588 * terminfo.c: Include tparam.h, to check interfaces.
23589 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23590 (tparam): Adjust signature to match interface in tparam.h;
23591 this removes some undefined behavior. Check that outstring and len
23592 are zero, which they always are with Emacs.
23593 * tparam.h (PC, BC, UP): New extern decls.
23595 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23596 (xftfont_open): Rename locals to avoid shadowing.
23598 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
23599 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
23600 (OTF_TAG_SYM): Omit macro if not needed.

23608 * xml.c (make_dom): Now static.
23610 * composite.c (composition_compute_stop_pos): Rename local to
23612 (composition_reseat_it): Remove unused locals.
23613 (find_automatic_composition, composition_adjust_point): Likewise.
23614 (composition_update_it): Mark var as initialized.
23615 (find_automatic_composition): Mark vars as initialized,
23616 with a FIXME (Bug#8290).
23618 character.h: Rename locals to avoid shadowing.
23619 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23620 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23621 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23622 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23623 to avoid shadowing.
23625 * textprop.c (property_change_between_p): Remove; unused.
23627 * intervals.c (interval_start_pos): Now static.
23629 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23632 Rename locals to avoid shadowing.
23634 * sound.c (wav_play, au_play, Fplay_sound_internal):
23635 Fix pointer signedness.
23636 (alsa_choose_format): Remove unused local var.
23637 (wav_play): Initialize a variable to 0, to prevent undefined
23638 behavior (Bug#8278).
23640 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23642 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23644 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23645 clobbering (Bug#8298).
23646 * sysdep.c (sys_subshell): Likewise.
23647 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23649 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23650 This should get cleaned up, so that child_setup has the
23651 same signature on all platforms.
23653 * callproc.c (call_process_cleanup): Now static.
23654 (relocate_fd): Rename locals to avoid shadowing.
23656 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23658 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23659 not to be necessary, and produces flickering.
23661 2011-03-20 Glenn Morris <rgm@gnu.org>
23663 * config.in: Remove file.
23665 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23667 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23668 are now in src/globals.h.
23669 (syms_of_minibuf): Remove spurious & from previous change.
23671 2011-03-20 Leo Liu <sdl.web@gmail.com>
23673 * minibuf.c (completing-read-function): New variable.
23674 (completing-read-default): Rename from completing-read.
23675 (completing-read): Call completing-read-function.
23677 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23679 * xfaces.c (Fx_load_color_file):
23680 Read color file from absolute filename (bug#8250).
23682 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23684 * makefile.w32-in: Update dependencies.
23686 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23688 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23694 * process.c (make_serial_process_unwind, send_process_trap):
23695 (sigchld_handler): Now static.
23697 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23698 That way, the code declares only the vars that it needs.
23699 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
23700 * s/cygwin.h (PTY_ITERATION): Likewise.
23701 * s/darwin.h (PTY_ITERATION): Likewise.

23707 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
23708 (CONSTANTLIM): Remove; unused.
23709 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23710 Define only if needed.
23712 * unexelf.c (unexec): Name an expression,
23713 to avoid gcc -Wbad-function-cast warning.
23714 Use a different way to cause a compilation error if anyone uses
23715 n rather than nn, a way that does not involve shadowing.
23716 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23718 * deps.mk (unexalpha.o): Remove; unused.
23720 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23721 * unexec.h: New file.
23722 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23723 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23724 Depend on unexec.h.
23725 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23726 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23727 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23728 Change as necessary to match prototype in unexec.h.
23730 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
23732 (back_comment, skip_chars): Mark vars as initialized.

23746 instead of using an uninitialized var.
23747 (font_sort_entities): Mark var as initialized.
23749 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
23751 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

23763 * floatfns.c (domain_error2): Define only if needed.
23764 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
23766 * alloc.c (mark_backtrace): Move decl from here ...

23775 * callint.c (quotify_arg, quotify_args): Now static.
23776 (Fcall_interactively): Rename locals to avoid shadowing.
23777 Use const pointer when appropriate.
23779 * lisp.h (get_system_name, get_operating_system_release):
23780 Move decls here, to check interfaces.
23781 * process.c (get_operating_system_release): Move decl to lisp.h.
23782 * xrdb.c (get_system_name): Likewise.
23783 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23784 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23785 some of which prompt warnings from gcc -Wbad-function-cast.
23786 (Fformat_time_string, Fencode_time, Finsert_char):
23787 (Ftranslate_region_internal, Fformat):
23788 Rename or remove local vars to avoid shadowing.
23789 (Ftranslate_region_internal): Mark var as initialized.
23791 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23794 * lisp.h (eassert): Check that the argument compiles, even if
23795 ENABLE_CHECKING is not defined.
23797 * data.c (Findirect_variable): Name an expression, to avoid
23798 gcc -Wbad-function-cast warning.
23799 (default_value, arithcompare, arith_driver, arith_error): Now static.

23806 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
23807 Rename locals to avoid shadowing.
23808 (mark_stack): Move local variables into the #ifdef region where
23810 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23811 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23813 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23814 (GC_STRING_CHARS): Remove; not used.
23815 (Fmemory_limit): Cast sbrk's returned value to char *.
23817 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23818 avoids undefined behavior in theory.
23820 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23822 Use functions, not macros, for up- and down-casing (Bug#8254).
23823 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23824 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23825 to use the following functions instead of these macros.
23826 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23827 EMACS_INT, since callers assume the returned value fits in int.
23828 (upcase1): Likewise, for UPCASE_TABLE.
23829 (uppercasep, lowercasep, upcase): New static inline functions.
23830 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23831 the race-condition problem in the old DOWNCASE.
23833 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
23834 Rename locals to avoid shadowing.
23835 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
23836 (regex_compile, re_search_2, re_match_2_internal):
23837 Remove unused local vars.
23838 (FREE_VAR): Rewrite so as not to use empty "else",
23839 which gcc can warn about.
23840 (regex_compile, re_match_2_internal): Mark locals as initialized.
23841 (RETALLOC_IF): Define only if needed.
23842 (WORDCHAR_P): Likewise. This one is never needed, but is used
23843 only in a comment talking about a compiler bug, so put inside
23844 the #if 0 of that comment.
23845 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23846 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23849 * search.c (boyer_moore): Rename locals to avoid shadowing.
23850 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
23851 (PREV_CHAR_BOUNDARY): Likewise.
23853 * search.c (simple_search): Remove unused var.
23855 * dired.c (compile_pattern): Move decl from here ...

23861 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
23863 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23864 Rename locals to avoid shadowing.
23865 (Fvertical_motion): Mark locals as initialized.
23867 * casefiddle.c (casify_object, casify_region): Now static.
23868 (casify_region): Mark local as initialized.
23870 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
23872 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23873 New macros, so that the caller can use some names other than
23874 gcpro1, gcpro2, etc.
23875 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23877 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23878 argument, for consistency with GCPRO2_VAR, etc: it is now the
23879 prefix of the variable, not the variable itself. All uses
23881 * dired.c (directory_files_internal, file_name_completion):
23882 Rename locals to avoid shadowing.
23884 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23885 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23886 dired.c's scmp function, had undefined behavior.
23887 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23888 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23889 * buffer.h: ... to here, because these macros use current_buffer,
23890 and the new implementation with inline functions needs to have
23891 current_buffer in scope now, rather than later when the macros
23893 (downcase, upcase1): New static inline functions.
23894 (DOWNCASE, UPCASE1): Reimplement using these functions.
23895 This avoids undefined behavior in expressions like
23896 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23897 from race conditions in accessing the global variables
23898 case_temp1 and case_temp2.
23899 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23900 * lisp.h (case_temp1, case_temp2): Remove their decls.
23901 * character.h (ASCII_CHAR_P): Move from here ...
23902 * lisp.h: ... to here, so that the inline functions mentioned
23903 above can use them.
23905 * dired.c (directory_files_internal_unwind): Now static.
23907 * fileio.c (file_name_as_directory, directory_file_name):
23908 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23910 (file_name_as_directory): Use const pointers when appropriate.
23911 (Fexpand_file_name): Likewise. In particular, newdir might
23912 point at constant storage, so make it a const pointer.
23913 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23914 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23916 (Fset_file_times, Finsert_file_contents, auto_save_error):
23917 Rename locals to avoid shadowing.
23919 * minibuf.c (choose_minibuf_frame_1): Now static.
23920 (Ftry_completion, Fall_completions): Rename or remove locals
23921 to avoid shadowing.
23923 * marker.c (bytepos_to_charpos): Remove; unused.
23925 * lisp.h (verify_bytepos, count_markers): New decls,
23926 so that gcc does not warn that these functions aren't declared.
23928 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23929 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23930 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23931 (copy_text): Remove unused local var.
23933 * filelock.c (within_one_second): Now static.
23934 (lock_file_1): Rename local to avoid shadowing.
23936 * buffer.c (fix_overlays_before): Mark locals as initialized.
23937 (fix_start_end_in_overlays): Likewise. This function should be
23938 simplified by using pointers-to-pointers, but that's a different
23940 (switch_to_buffer_1): Now static.
