534 * xdisp.c (row_for_charpos_p): New function, with code of
535 cursor_row_p, but accepts an additional argument CHARPOS instead
536 of using a hardcoded PT.
537 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
538 (row_containing_pos): Call row_for_charpos_p instead of partially
539 doing the same. Fixes cursor positioning under longlines-mode
540 when longlines-show-effect includes more than one newline, when
541 moving the cursor vertically up.
543 2013-05-08 Juanma Barranquero <lekktu@gmail.com>

561 * unexelf.c: Don't assume ElfW (Half) fits in int.
562 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
563 when dealing with ElfW (Half) values, since they can exceed 2**31
564 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
565 (entry_address): Omit unused NUM arg. All uses changed.
567 2013-05-07 Juri Linkov <juri@jurta.org>

596 (x_get_monitor_attributes_fallback): Omit unused locals.
597 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
598 Use double, not float, to avoid mixed-mode floating point arithmetic.

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

666 Use prototype rather than old-style definition.
667 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
668 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
669 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
670 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
671 Don't assume ptrdiff_t, size_t, and long are the same width as int.
672 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
673 This matters only when DEBUG is defined.
675 2013-05-05 Eli Zaretskii <eliz@gnu.org>
677 * xdisp.c (set_iterator_to_next): Set the
678 ignore_overlay_strings_at_pos_p flag only if we are _really_
679 iterating over an overlay string, as indicated by the
680 current.overlay_string_index member. (Bug#14306)
682 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
684 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
685 to where it is used, to avoid autorelease issues (Bug#14050).
687 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
689 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
690 * fileio.c (syms_of_fileio): Implement this.
691 * filelock.c (create_lock_file): If symbolic links don't work, so
692 we use a regular file as a lock file, do not fsync the lock file;
695 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
697 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

706 Use parentheses to disambiguate last part of the condition.
708 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
709 assertion violations. (Bug#14062)
711 2013-05-01 David Reitter <david.reitter@gmail.com>
713 * nsfns.m (ns_tooltip): Initialize.
715 2013-04-28 Eli Zaretskii <eliz@gnu.org>
717 * coding.c (decode_coding_gap): Don't remove the character before
718 a newline unless it's a CR character. (Bug#14287)
720 2013-04-28 Dan Nicolaescu <dann@gnu.org>
722 * dispextern.h (struct face): Move enum face_underline_type

727 * nsfns.m (handlePanelKeys): New function.
728 (EmacsOpenPanel:performKeyEquivalent:)
729 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle

732 2013-04-27 Juri Linkov <juri@jurta.org>
734 * callint.c (Fcall_interactively): Call `Qread_number' for
735 interactive code letter `n' instead of using duplicate code.
738 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
740 * systime.h (make_timeval): Declare as 'const'.
742 2013-04-27 Kenichi Handa <handa@gnu.org>
744 * font.c (font_open_entity): Always open a font of manageable
747 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
749 Port better to AIX (Bug#14258).
750 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
753 2013-04-24 Kenichi Handa <handa@gnu.org>

756 sequence is encountered, reset the invocation and designation
757 status to the safest one.
759 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
761 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
762 Without this fix, "make distclean" leaves stamp-h1 behind.
764 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
766 * w32fns.c (w32_fullscreen_rect): New function to compute the
767 window rectangle for the given fullscreen mode.
768 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
769 longer tunes the window size. This keeps the window's edges flush
770 with the screen and allows the taskbar to hide itself in fullboth.
772 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
773 window decorations and uses the entire screen.
775 * w32term.h (w32_fullscreen_rect) Add prototype.
776 (struct w32_output): Replace normal_width, normal_height,
777 normal_top, and normal_left members with a single normal_placement

795 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
796 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
797 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
798 parentheses where appropriate.
800 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
802 * keyboard.c (timer_start_idle): Remove no-longer-used local.
804 2013-04-14 Eli Zaretskii <eliz@gnu.org>
806 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
807 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
808 Mention in the doc string that setting these variables takes
809 effect only after a call to set-window-buffer. (Bug#14200)
811 2013-04-13 Eli Zaretskii <eliz@gnu.org>
813 * indent.c (Fvertical_motion): Don't consider display strings on
814 overlay strings as display strings on the buffer position we
815 started from. This prevents vertical cursor motion from jumping
816 more than one line when there's an overlay string with a display
817 property at end of line.
818 Reported by Karl Chen <Karl.Chen@quarl.org> in
819 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

824 already selected (bug#14191).
826 2013-04-11 Eli Zaretskii <eliz@gnu.org>
828 * window.c (Fwindow_end): Test more flags, including the buffer's
829 last_overlay_modified flag, to determine whether the window's
830 display is really up-to-date. Prevents the function from
831 returning a stale value. (Bug#14170)
832 (Fwindow_line_height): Fix the test for up-to-date-ness of the
835 2013-04-10 Eli Zaretskii <eliz@gnu.org>
837 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
838 garbaged only if it is not already the top frame on its TTY.
839 This prevents flickering due to constant redrawing of TTY frames when
840 there are GUI frames open in the same session. (Bug#13864)
842 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
844 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
845 of marking the idle timers directly.
847 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
849 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
852 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

871 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
874 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
876 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
877 This bug was introduced by my 2013-02-25 change that simplified
878 data_start configuration. Without this change, on GNU/Linux
879 an Emacs configured with --enable-profiling fails immediately
880 due to a profiler signal.
881 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
882 with these flags. On platforms where special flags are needed
883 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
884 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
885 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
887 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

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

1088 Use contents slot, not buffer, where appropriate.
1089 * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
1090 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1091 (expose_window_tree): Likewise.
1092 Use contents slot, not buffer, where appropriate.
1093 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1094 to avoid deleted windows. Use contents slot instead of buffer.
1095 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
1096 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

1430 * coding.h (struct coding_system): New member eol_seen.
1432 * coding.c (detect_ascii): New function.
1433 (detect_coding): Set coding->head_ascii and coding->eol_seen only
1434 when the source bytes are actually scanned. On detecting for
1435 coding_category_utf_8_auto, call detect_ascii instead of scanning
1436 source bytes directly.
1437 (produce_chars): Call insert_from_gap with the new arg 0.
1438 (encode_coding): Likewise.
1439 (decode_coding_gap): Control ASCII optimization by the variable
1440 disable_ascii_optimization instead of #ifndef .. #endif.
1441 Deccode EOL format according to coding->eol_seen.
1442 (syms_of_coding): Declare disable-ascii-optimization as a Lisp
1445 * lisp.h (adjust_after_replace): Cancel externing it.

1458 (pp_cache): Put under ENABLE_CHECKING.
1460 2013-03-14 Eli Zaretskii <eliz@gnu.org>
1462 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
1463 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
1465 (w32fullscreen_hook): If the frame is visible, reset
1466 f->want_fullscreen flag after changing the frame size. If the
1467 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1470 2013-03-13 Daniel Colascione <dancol@dancol.org>
1472 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1473 too so that these builds can use Cygwin's file conversion
1474 functions. (We've been building and linking cygw32.o all along
1475 and just not using it.)
1477 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1479 File synchronization fixes (Bug#13944).
1480 * Makefile.in (LIB_FDATASYNC): New macro.
1482 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
1483 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
1484 Don't worry about HAVE_FSYNC, since a substitute fsync is
1485 available if the system lacks one.
1486 (Fwrite_regin): Retry fsync if interrupted.
1488 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1490 * w32term.c (w32_read_socket): If the Emacs frame is being
1491 activated, call w32fullscreen_hook, to make sure the new frame
1492 dimensions are in effect. (Bug#13937)
1494 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1496 * xdisp.c (init_iterator): Simplify because both character and byte
1497 positions are either specified or -1. Add eassert. Adjust comment.
1498 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1499 character and byte positions can be obtained from marker.
1501 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1503 Static checking by Sun C 5.12.

1516 a function pointer type; the C Standard requires this.
1518 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1519 Include <sys/param.h> unconditionally, as that works elsewhere and
1520 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1521 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1524 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
1526 * insdel.c (adjust_after_replace): Use bool for boolean.

1550 call ShellExecute in cygw32 builds.
1552 * w32fn.c (Fx_file_dialog): Use the above macros to simplify the
1553 common file dialog code.
1555 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1556 can just use du like other systems.
1558 * coding.c (from_unicode_buffer): Declare.
1559 * coding.c (from_unicode_buffer): Implement.
1561 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1605 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
1607 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1608 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1609 from Elisp via unread-command-events.
1611 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1612 functions to mean "no change".
1614 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1616 region-cache.c, scroll.c, search.c: Use bool for booleans.
1617 * lisp.h (compile_pattern):

1622 (search_regs_saved, Fregexp_quote):
1623 Use bool for boolean.
1624 * region-cache.c (region_cache_forward, region_cache_backward):
1625 Fix comments to match code: these functions return int, not boolean.
1627 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1629 * search.c (find_newline): Accept start and end byte positions
1630 as arguments and allow -1 if not known.
1631 (find_newline_no_quit): Likewise for start position.
1632 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1633 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1634 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1635 * editfns.c (Fconstrain_to_field): Break long line.
1636 Adjust call to find_newline.
1637 * indent.c (vmotion): Adjust calls to find_newline_no_quit.
1638 Use DEC_BOTH to start next search from the previous buffer
1639 position, where appropriate.
1640 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1641 (get_visually_first_element, move_it_vertically_backward): Likewise.
1642 Obtain byte position from the display iterator, where appropriate.
1644 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1646 print.c, process.c: Use bool for booleans.
1647 * lisp.h (wait_reading_process_output):
1648 * print.c (print_output_debug_flag, PRINTDECLARE, printchar)
1649 (strout, debug_output_compilation_hack, float_to_string, print)

1662 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1664 * bidi.c (bidi_fetch_char): Swap first and second arguments
1665 to match other functions accepting character and byte positions.
1667 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1668 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1669 when you need just to move to the previous buffer position.
1670 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1672 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1684 (vmotion): Use byte position argument and avoid call to CHAR_TO_BYTE.
1685 Adjust comments, style and calls to compute_motion.
1686 (Fvertical_motion): Adjust call to vmotion.
1687 * window.c (Fdelete_other_windows_internal): Record window start
1688 byte position and adjust call to vmotion.
1689 (window_scroll_line_based): Likewise with call to compute_motion.
1691 (Frecenter): Adjust calls to vmotion.
1693 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1695 * lisp.h (list2i, list3i): New functions.
1696 (list4i): Move from window.c and make LISP_INLINE.
1697 * editfns.c (make_lisp_time):
1698 * fns.c (Flocale_info):
1699 * keyboard.c (parse_modifiers):
1700 * xterm.c (x_ewmh_activate_frame): Use list2i.

1709 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1711 * search.c (find_newline_no_quit): Rename from find_next_newline.
1714 * lisp.h (find_newline_no_quit): Rename prototype.
1716 * xdisp.c (back_to_previous_line_start)

1718 (move_it_vertically_backward): Callers of find_newline_no_quit changed.
1719 * indent.c (vmotion): Callers of find_newline_no_quit changed.
1720 * bidi.c (bidi_find_paragraph_start): Callers of
1721 find_newline_no_quit changed.

1726 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1728 Coding system support cleanup and minor refactoring.
1729 * coding.h (enum coding_result_code): Remove
1730 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1731 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1732 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1733 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
1734 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.
1735 (decode_coding_region, encode_coding_region, decode_coding_string):
1736 Remove unused compatibility macros.

1738 (record_conversion_result): Adjust user.
1739 (syms_of_coding): Likewise.
1740 (ALLOC_CONVERSION_WORK_AREA): Use SAFE_ALLOCA.
1741 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1742 (decode_coding_object): Simplify since xrealloc never returns NULL.
1745 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1747 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1748 * sysdep.c (list_system_processes)
1749 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1750 Make it a stub in this case; otherwise the build might fail,
1751 and this code hasn't been tested on such hosts anyway.
1752 Problem reported by Nelson H. F. Beebe in
1753 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1754 and analyzed by Jérémie Courrèges-Anglas in
1755 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1757 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1759 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1760 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1761 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1762 * bidi.c (bidi_find_paragraph_start): Likewise.
1763 * indent.c (vmotion): Likewise.
1765 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1767 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1768 * filelock.c: Include <c-ctype.h>.
1769 (MAX_LFINFO): New top-level constant.
1770 (lock_info_type): Remove members pid, boot_time. Add members at,
1771 dot, colon. Change user member to be the entire buffer, not a
1772 pointer. This allows us to handle the case where a foreign
1773 pid or boot time exceeds the local range. All uses changed.
1774 (LINKS_MIGHT_NOT_WORK): New constant.
1775 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1776 (defined_WINDOWSNT): Remove.
1777 (MAKE_LOCK_NAME, file_in_lock_file_name):
1778 Always use .#FILE (not .#-FILE) for the file lock,
1779 even if it is a regular file.
1780 (rename_lock_file): New function.
1781 (create_lock_file): Use it.
1782 (create_lock_file, read_lock_data):
1783 Prefer a symbolic link for the lock file, falling back on a
1784 regular file if symlinks don't work. Do not try to create
1785 symlinks on MS-Windows, due to security hassles. Stick with
1786 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1787 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1788 host may be using a Windowsish file system, and cannot use
1789 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1790 doesn't work. Don't fail merely because of a symlink-contents
1791 length limit in the current file system; fall back on regular
1792 files. Increase the symlink contents length limit to 8 KiB, this
1793 should be big enough for any real use and doesn't crunch the
1795 (create_lock_file, lock_file_1, read_lock_data):
1796 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1797 (lock_file_1): Return error number, not bool. All callers changed.
1798 (ELOOP): New macro, if not already defined.
1799 (read_lock_data): Return size of lock file contents, not Lisp object.
1800 All callers changed. Handle a race condition if some other process
1801 replaces a regular-file lock with a symlink lock or vice versa,
1802 while we're trying to read the lock.
1803 (current_lock_owner): Parse contents more carefully, to help avoid
1804 confusing a regular-file lock with some other application's use
1805 of the file. Check for lock file contents being too long, or
1806 not parsing correctly.
1807 (current_lock_owner, lock_file):
1808 Allow foreign pid and boot times that exceed the local range.
1809 (current_lock_owner, lock_if_free, lock_file):
1810 Simplify allocation of lock file contents.
1811 * w32.c (sys_rename_replace): New function, containing most of
1812 the contents of the old sys_rename.
1813 (sys_rename): Use it.
1814 (fchmod): New dummy function.
1815 * w32.h (sys_rename_replace, fchmod): New decls.
1817 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1819 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1820 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1821 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1822 <dmantipov@yandex.ru>.
1824 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1826 * composite.c (get_composition_id, fill_gstring_header):
1827 Use make_uninit_vector where appropriate.
1828 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1829 * xselect.c (clean_local_selection_data): Likewise.
1831 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1833 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1834 * image.c (imagemagick_load_image): Calculate height and width
1835 after flattening the image, not before.
1837 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1839 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1840 * ftfont.c (ftfont_shape_by_flt): Likewise.
1841 * w32uniscribe.c (uniscribe_shape): Likewise.
1843 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1845 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1846 The old approach, which fell back on DIR/.#FILE.0 through
1847 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1848 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1849 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1850 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1851 because the locking mechanism was never reliable in that case).
1852 This patch fixes this and other bugs discovered by a code
1853 inspection that was prompted by
1854 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1855 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1856 to avoid interoperability problems between the MS-Windows and
1857 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1858 instances of Emacs now ignore each others' locks.
1859 * filelock.c (defined_WINDOWSNT): New constant.
1860 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1861 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1862 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1863 regular files on MS-Windows hosts.
1864 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1865 Use SAFE_ALLOCA to avoid problems with long file names.
1866 (MAX_LFINFO): Now a local constant, not a global macro.
1867 (IS_LOCK_FILE): Remove.
1868 (lock_file_1): Don't inspect errno if symlink call succeeds;
1869 that's not portable.
1870 (lock_file): Document that this function can return if lock
1872 (lock_file): Don't access freed storage.
1874 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1884 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1886 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1887 If the interval tree changes as a side effect of calling
1888 modify_region, re-do processing starting from the call to
1889 validate_interval_range. (Bug#13743)
1891 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1893 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1896 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1898 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with

1900 access to the lock file until it is written and closed.
1903 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1905 * callint.c (Qcall_interactively):

1915 Minor textprop integer cleanup.
1916 * intervals.h, textprop.c (add_text_properties_from_list):
1917 Return void, not int, since nobody uses the return value.
1918 * textprop.c (validate_plist, add_properties, remove_properties)
1919 (Fadd_text_properties):
1920 Don't assume list length fits in int.

1932 Implement CLASH_DETECTION for MS-Windows.
1934 * filelock.c [WINDOWSNT]: Include w32.h.

1936 function of that name. Up-case the macro arguments.
1937 (IS_LOCK_FILE): New macro.
1938 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.

1942 the lock information as its contents.
1943 (read_lock_data): New function, on Posix platforms just calls
1945 [WINDOWSNT]: Read the lock info from the file.
1946 (current_lock_owner): Call read_lock_data instead of calling
1947 emacs_readlinkat directly.
1948 (lock_file) [WINDOWSNT]: Run the file name through
1951 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1952 just check if the process by that PID exists.
1954 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1955 also present, as doing so will fail to error out if the file
1958 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1960 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1961 (Fremove_list_of_text_properties): Skip all of the intervals in
1962 the region between START and END that already have resp. don't
1963 have the requested properties, not just the first one.
1964 Add assertions that the loop afterwards always modifies the
1965 properties. (Bug#13743)
1967 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1969 * callint.c (Fcall_interactively): Use the right lexical environment

1983 (temacs$(EXEEXT)): Use $(ALLOBJS).
1984 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1985 * deps.mk (vm-limit.o):
1986 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1987 Do not depend on mem-limits.h.
1988 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1989 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1995 * vm-limit.c: Move most of mem-limits.h's contents here.
1996 (data_start): New decl. It's OK if this is approximate,
1997 so simplify-away some unnecessary exactness.
1998 (POINTER): Remove; all uses removed.
1999 (data_space_start): Now char *, to avoid casts.
2000 (exceeds_lisp_ptr): New function, replacing the old

2017 and diagnosed by Andreas Schwab in
2018 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
2020 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2022 Assume C89 or better.
2023 * ralloc.c (SIZE, POINTER, NIL):
2024 * vm-limit.c (POINTER):
2025 Remove, replacing all uses with C89 equivalents. These old
2026 symbols were present only for porting to pre-C89 platforms.
2028 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
2030 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
2031 This avoids warning messages reported as part of Bug#13546.
2033 2013-02-21 Ken Brown <kbrown@cornell.edu>
2035 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
2037 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
2039 * sheap.c (report_sheap_usage): Prefer message1_nolog.
2041 * keyboard.c (Qcommand_execute): New var.
2042 (command_loop_1, read_char): Use it.
2043 (Fcommand_execute): Remove, replace by an Elisp implementation.

2046 2013-02-19 Daniel Colascione <dancol@dancol.org>
2048 * sheap.c (report_sheap_usage): Use message, not message1, so
2049 that we don't try to create a buffer while we're in the middle
2050 of dumping Emacs. Explain why.
2052 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2054 * search.c (find_newline): Return byte position in bytepos.
2056 (find_next_newline_no_quit, find_before_next_newline):
2057 Add bytepos argument.
2058 * lisp.h (find_newline, find_next_newline_no_quit)

2064 (get_visually_first_element, move_it_vertically_backward):
2065 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
2067 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2069 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2070 resources were not orderly released.
2072 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2074 * xdisp.c (x_draw_vertical_border): For a window that is neither
2075 the leftmost nor the rightmost, redraw both the left and the right
2076 vertical borders. (Bug#13723)
2078 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

2088 * callint.c (Fcall_interactively):
2089 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
2091 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
2093 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
2094 * frame.c (syms_of_frame): ... to here.
2096 2013-02-16 Eli Zaretskii <eliz@gnu.org>
2098 * w32.c (sys_chown): Remove unused function.
2100 * w32term.c <input_signal_count>: Declare 'volatile'
2101 unconditionally. (Bug#9066)
2103 * w32.c (set_errno): Reset h_errno and don't set it to any other
2104 value. Set errno instead.
2105 (check_errno): Reset h_errno.
2106 (sys_socket, socket_to_fd, sys_bind, sys_connect)
2107 (sys_gethostname, sys_getservbyname, sys_getpeername)
2108 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2109 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
2111 (sys_gethostbyname): Set h_errno only errors detected.
2113 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2115 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
2117 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2119 * keyboard.c (read_char): Fix calculation of auto-save time out
2120 when auto-save-timeout is less than 4. (Bug#13720)
2122 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
2123 time. Improve diagnostics in DebPrint. (Bug#13546)

2128 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
2129 make sure errno is set to an appropriate value. (Bug#13546)
2130 (socket_to_fd): Add assertion against indexing fd_info[] with a
2131 value that is out of bounds.
2132 (sys_accept): If fd is negative, do not set up the child_process
2133 structure for reading.
2135 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
2137 * composite.c (fill_gstring_header): Remove useless prototype.

2144 (get_overlay_arrow_glyph_row, display_mode_element):
2145 (decode_mode_spec_coding, message3):
2146 * xfaces.c (face_at_string_position): Use bool for booleans.
2149 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2151 Fix AIX port (Bug#13650).
2152 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2153 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2154 was #undeffed earlier, so it cannot be used as a macro here.
2155 Use the constant and not the macro.
2157 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2159 * w32proc.c (new_child): If no vacant slots are found in
2160 child_procs[], make another pass looking for slots whose process
2161 has exited or died. (Bug#13546)
2163 * w32.c (sys_pipe): When failing due to file descriptors above
2164 MAXDESC, set errno to EMFILE.
2165 (_sys_read_ahead): Update cp->status when failing to read serial
2166 communications input, so that the status doesn't stay at
2167 STATUS_READ_IN_PROGRESS. (Bug#13546)
2169 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2171 * gtkutil.c (tb_size_cb): New function.
2172 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2174 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2176 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2179 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2181 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2183 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
2185 * font.c (font_range): Add pos_byte argument. Adjust comment
2186 and break long line.
2187 * font.h (font_range): Adjust prototype.
2188 * composite.c (autocmp_chars): Pass byte position to font_range.
2189 Break long line. Remove useless prototype and format comment.
2191 2013-02-13 Glenn Morris <rgm@gnu.org>
2193 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2195 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2197 Improve AIX port some more (Bug#13650).
2198 With this, it should be as good as it was in 23.3, though it's
2199 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2200 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2201 * unexaix.c (start_of_text): Remove.
2202 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2203 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2204 (orig_load_scnptr, orig_data_scnptr):
2205 Now off_t, not long, since they are file offsets.
2206 (make_hdr): Use _data, not start_of_data ().
2207 This is the key part of the fix.
2208 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2209 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2211 * pre-crt0.c (data_start): Initialize to 1.
2212 This ports to compilers that optimize the external declaration
2213 'int x = 0;' as if it were 'int x;' to shrink the executable.
2215 Improve AIX port (Bug#13650).
2216 This doesn't fix the bug, but it makes progress: Emacs builds now.
2217 * unexaix.c: Include inttypes.h, stdarg.h.
2218 (report_error, report_error_1): Mark as _Noreturn.
2219 (report_error): Don't report the wrong errno.
2220 (report_error_1): Now varargs. All callers changed.
2221 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2222 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2223 (write_ptr): Use %p to print address rather than %lx and a cast
2224 to unsigned long. Grow buffer a bit, to be safer.
2226 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2228 * bidi.c (bidi_resolve_neutral): After finding the next
2229 non-neutral character, accept NEUTRAL_ON type as well, because
2230 directional control characters, such as LRE and RLE, have their
2231 type converted to that by bidi_resolve_weak. This avoids aborts
2232 when LRE/RLE follows a run of neutrals.
2233 (bidi_move_to_visually_next): Assert that return value of
2234 bidi_peek_at_next_level is non-negative. Negative values will
2237 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2239 Minor getenv-related fixes.
2240 * callproc.c (Fcall_process_region) [!DOS_NT]:
2241 Avoid unnecessary duplicate call to getenv.
2242 * callproc.c (init_callproc):
2243 * dispnew.c (init_display):
2244 * sysdep.c (sys_subshell):
2245 Omit unnecessary cast of getenv or egetenv.
2247 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2249 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2250 Update dependencies.
2252 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2254 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2256 (display_line): Set w->region_showing to the value of
2257 it->region_beg_charpos, not to -1. This fixes redisplay
2258 optimization when cursor is moved up after M->. (Bug#13623)
2260 (try_scrolling): Scroll text up more if point is too close to ZV
2261 and inside the scroll margin. This makes sure point is moved
2262 outside the scroll margin in these cases.
2264 * window.h (struct window): region_showing can no longer be
2267 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2269 Tune by using memchr and memrchr.
2270 * doc.c (Fsnarf_documentation):
2271 * fileio.c (Fsubstitute_in_file_name):
2272 * search.c (find_newline, scan_newline):
2273 * xdisp.c (pos_visible_p, display_count_lines):
2274 Use memchr and memrchr rather than scanning byte-by-byte.
2275 * search.c (find_newline): Rename from scan_buffer.
2276 Omit first arg TARGET, as it's always '\n'. All callers changed.
2278 Clean up read_key_sequence a tiny bit more.
2279 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2280 (read_key_sequence): Remove unused locals.
2282 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2284 Clean up read_key_sequence a bit; reread active keymaps after first event.
2285 * keyboard.c (read_char, read_char_x_menu_prompt)
2286 (read_char_minibuf_menu_prompt):
2287 Replace nmaps+maps with a single `map' arg.
2288 (follow_key): Operate on a single map.
2289 (active_maps): New function.
2290 (test_undefined): Also return true for nil bindings.
2291 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2292 a single (composed) keymap. Remember `first_event' to choose the right
2293 set of active keymaps. Recompute the set of keymaps after receiving
2294 the first event. Remove GOBBLE_FIRST_EVENT.
2295 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2296 * keyboard.h (read_char): Update declaration.
2297 * lread.c (read_filtered_event): Adjust call to read_char.
2299 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2301 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2302 Don't use the limitation on backwards movement when lines are truncated
2303 in the window. (Bug#13675)
2305 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2307 * marker.c (set_marker_internal): If desired position is passed
2308 as a marker, avoid call to buf_charpos_to_bytepos.
2309 * window.c (Fset_window_point): Omit redundant type checking.
2310 (Fset_window_start): Likewise. Format comment.
2311 (window_scroll_pixel_based): Use set_marker_restricted_both
2312 with character and byte positions obtained from an iterator.
2313 (Fset_window_configuration): Use set_marker_restricted_both.
2314 * xdisp.c (message_dolog): Likewise.
2316 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2318 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2319 When text lines are longer than window's screen lines, don't move back
2320 too far. This speeds up some redisplay operations. (Bug#13675)
2322 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2324 * syntax.c (scan_sexps_forward): Fix byte position calculation
2325 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2327 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2329 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2330 that was not needed.
2332 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2334 Minor hashing refactoring.
2335 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2336 (sxhash_float): Return EMACS_UINT, for consistency with the other
2338 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2339 non-static inline function and therefore can't use static vars.
2340 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2341 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2342 with the other hash functions.
2344 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2346 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2347 XXXXXX part of the temporary file pattern is not downcased even
2348 when w32-downcase-file-names is non-nil. (Bug#13661)
2350 * xdisp.c (decode_mode_spec): Remove handling of %t.
2352 * msdos.c (careadlinkatcwd): Remove.
2354 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2356 * lread.c (skip_dyn_bytes): New function (bug#12598).
2357 (read1): Use it. Use getc instead of READCHAR to read bytes.
2358 (load_each_byte): Remove. Update users.
2360 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2362 * search.c (scan_buffer): Calculate end byte position just once.

2370 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2372 * lisp.h (make_uninit_vector): New function.
2373 * alloc.c (Fvector, Fmake_byte_code):

2389 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2391 * coding.c (Fdefine_coding_system_internal): Use AREF where
2392 argument is known to be a vector.
2393 * fns.c (Flocale_info): Likewise for ASET.
2394 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2395 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2397 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2399 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2402 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

2406 * nsterm.m (NEW_STYLE_FS): Remove.
2407 (ns_last_use_native_fullscreen): New variable.
2408 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2409 (x_set_window_size): Do not take title bar and tool bar into account
2410 if isFullscreen returns YES.
2411 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2412 (check_native_fs): New function.
2413 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2414 (ns_term_init): Remove NEW_STYLE_FS.
2415 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2416 and tool bar if isFullscreen returns NO.
2417 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2418 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2419 with HAVE_NATIVE_FS.
2420 (window:willUseFullScreenPresentationOptions:): New method.
2421 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.

2429 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2430 (syms_of_nsterm): Add ns-use-native-fullscreen.
2432 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2434 * fileio.c (Qchoose_write_coding_system): Now static.
2436 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2438 * xdisp.c (window_buffer_changed): region_showing can be negative,
2439 which still means region is being displayed.
2440 (redisplay_internal): Resurrect code that forced redisplay of the
2441 whole window when showing region and the mark has changed.
2442 Record the new mark position to allow redisplay optimizations.
2443 (display_line): If it->region_beg_charpos is non-zero, set the
2444 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2446 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2447 not bitfield of 1 bit.
2449 2013-02-03 Daniel Colascione <dancol@dancol.org>
2451 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2452 daemon mode works on cygw32 when Emacs is installed and not just
2455 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2457 Avoid file time stamp bug on MS-Windows (Bug#13149).
2458 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2459 as FAT32 doesn't update time stamps when truncating them.
2460 Also, check that a file time stamp is not a multiple of 100 ns;
2461 this should catch all instances of the problem on MS-Windows,
2462 as its native file system resolution is 100 ns or worse, and
2463 checking for a non-multiple of 100 ns should impose only a small
2464 overhead on systems with ns resolution.
2466 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2468 Avoid encoding file names on MS-Windows when they need to be run
2469 through dostounix_filename.
2470 * w32.c (normalize_filename): Accept an additional argument
2471 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2472 downcase it even if w32-downcase-file-names is non-nil.
2473 (dostounix_filename): Accept an additional argument MULTIBYTE and
2474 pass it to normalize_filename.
2475 (emacs_root_dir): Adjust.
2477 * msdos.h (dostounix_filename): Adjust prototype.
2479 * w32.h (dostounix_filename): Adjust prototype.
2481 * msdos.c (dostounix_filename): Accept an additional argument and
2483 (init_environment): Adjust callers of dostounix_filename.
2485 * fileio.c (Ffile_name_directory, file_name_as_directory)
2486 (directory_file_name, Fexpand_file_name)
2487 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2489 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2491 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2492 variables, as egetenv is case-insensitive for DOS_NT.
2494 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2495 with an encoded file name.
2497 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2498 Adjust calls to dostounix_filename.
2500 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2502 * unexw32.c (unexec): Adjust call to dostounix_filename.
2504 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2506 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2509 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2512 * callproc.c (Fcall_process): Make sure program name in PATH and
2513 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2514 is passed to exec/spawnve, which fails unless the file-name
2517 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2518 even if w32-quote-process-args is nil.
2520 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2522 Fix timestamp bug when write-region appends nothing (Bug#13149).
2523 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2524 the file's time stamp doesn't change if Emacs happens to write nothing
2525 to the file, and on a buggy file system this could cause Emacs to
2526 incorrectly infer that the file system doesn't have the bug.
2527 Avoid this problem by inhibiting the inference in this case.
2529 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2531 * window.h (struct window): Convert base_line_number, base_line_pos
2532 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2533 Convert region_showing member from Lisp_Object to bitfield.
2534 Remove sequence_number member. Adjust comments.
2535 * window.c (sequence_number): Remove.
2536 (make_window): Initialize column_number_displayed.
2537 * print.c (print_object): Follow the printed representation of
2538 frames and print window pointer to distinguish between windows.
2539 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2540 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2541 (wset_column_number_displayed, wset_region_showing): Remove.
2542 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2543 (try_scrolling, try_cursor_movement, redisplay_window)
2544 (try_window_reusing_current_matrix, try_window_id, display_line)
2545 (display_mode_lines, decode_mode_spec): Adjust users.
2546 * .gdbinit (pwinx): Do not print sequence_number.
2548 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2550 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2551 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2552 * dired.c: Include <fcntl.h>.
2553 (open_directory): New function, which uses open and fdopendir
2554 rather than opendir. DOS_NT platforms still use opendir, though.
2555 (directory_files_internal, file_name_completion): Use it.
2556 (file_attributes): New function, with most of the old Ffile_attributes.
2557 (directory_files_internal, Ffile_attributes): Use it.
2558 (file_attributes, file_name_completion_stat): First arg is now fd,
2559 not dir name. All uses changed. Use fstatat rather than lstat +
2561 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2562 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2563 (emacs_readlinkat): New function, with much of the old
2564 Ffile_symlink_p, but with an fd argument for speed.
2565 It uses readlinkat rather than careadlinkatcwd, so that it
2566 need not assume the working directory.
2567 (Ffile_symlink_p): Use it.
2568 * filelock.c (current_lock_owner): Use emacs_readlinkat
2569 rather than emacs_readlink.
2570 * lisp.h (emacs_readlinkat): New decl.
2571 (READLINK_BUFSIZE, emacs_readlink): Remove.
2572 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2573 (emacs_norealloc_allocator, emacs_readlink): Remove.
2574 This stuff is moved to fileio.c.
2575 * w32.c (fstatat, readlinkat): New functions.
2576 (careadlinkat): Don't check that fd == AT_FDCWD.
2577 (careadlinkatcwd): Remove; no longer needed.
2579 2013-01-31 Glenn Morris <rgm@gnu.org>
2581 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2582 (Fwrite_region): Update for new choose_write_coding_system args.
2583 Move the last piece of choose_write_coding_system here. (Bug#13522)
2584 (syms_of_fileio): Add choose-write-coding-system.
2586 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2588 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2589 (sys_close): Zero out the flags for the file descriptor before
2590 closing it. (Bug#13546)
2592 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2593 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2594 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2597 * w32.c (w32_get_long_filename, init_environment, readlink):
2598 Support file names encoded in DBCS codepages.
2599 (readlink): Use the current file-name-coding-system, not the ANSI
2600 codepage, to decode and handle targets of symlinks.
2602 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2604 * w32.c (opendir): Now accepts a 'const char *'.
2606 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2608 Remove obsolete redisplay code. See the discussion at
2609 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2610 * dispnew.c (preemption_period, preemption_next_check): Remove.
2611 (Vredisplay_preemption_period): Likewise.
2612 (update_frame, update_single_window, update_window, update_frame_1):
2613 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2614 used, following the 2012-06-22 change.
2616 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2618 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2620 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2622 * font.c (num_fonts): Remove the leftover from old
2623 debugging code. Adjust comment style here and there.
2624 * insdel.c (insert_1): Remove.
2625 * lisp.h (insert_1): Remove prototype.
2626 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2628 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2630 * w32.c (max_filename_mbslen): New function.
2631 (normalize_filename, readdir): Use it to detect locales where ANSI
2632 encoding of file names uses a double-byte character set (DBCS).
2633 If a DBCS encoding is used, advance by characters using
2634 CharNextExA, instead of incrementing a 'char *' pointer.
2635 Use _mbslwr instead of _strlwr. (Bug#13515)
2637 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2638 request of memory reservation to 1.7GB. (Bug#13065)
2640 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2642 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2643 at check_extra_latin label. (Bug#13505)
2645 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2647 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2648 Avoid redundant calls to strlen.
2650 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2652 Drop async_visible and async_iconified fields of struct frame.
2653 This is possible because async input is gone; for details, see
2654 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2655 * frame.h (struct frame): Remove async_visible and async_iconified
2656 members, convert garbaged to unsigned bitfield. Adjust comments.
2657 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2658 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2659 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2660 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2661 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2663 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2664 properly. Likewise for obscured.
2666 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2669 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2671 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2673 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2674 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2676 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2678 * xdisp.c (message2, message2_nolog): Remove functions.
2679 (message3, message3_nolog): Extract nbytes and multibyteness directly
2680 from the string. Change all callers.
2681 (message3_nolog): Don't set message_enable_multibyte since set_message
2682 will reset it anyway.
2683 (message1, message1_nolog): Use message3.
2684 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2685 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2686 (set_message): Drop all but the second arg, which has to be a string.
2687 (set_message_1): Simplify now that we know that a1 is NULL and the
2688 second arg is a string.
2689 * frame.h (struct frame): Remove `message_buf' field.
2690 Use glyphs_initialized_p instead.
2691 (FRAME_MESSAGE_BUF): Remove macro.

2693 * lisp.h (message2, message2_nolog): Remove declarations.
2694 (message3, message3_nolog): Update declarations.
2695 * keyboard.c (read_char_minibuf_menu_text)
2696 (read_char_minibuf_menu_width): Remove vars.
2697 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2698 to correctly handle multibyte strings.
2699 * frame.c (delete_frame): Don't free message_buf any more.
2700 * editfns.c (message_text, message_length): Remove vars.
2701 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2702 * fileio.c (auto_save_error): Use message3 instead of message2.
2703 * dispnew.c (adjust_frame_message_buffer): Remove function.
2705 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2707 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2708 real estate used for the tool bar and the menu bar.
2710 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2712 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2713 hidden buffer is prepared to modification (Bug#13164).
2715 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2717 * window.h (struct window): Change window_end_valid member from
2718 Lisp_Object to a bitfield. Adjust comments.
2719 (wset_window_end_valid): Remove.
2720 * window.c (adjust_window_count): Clear window_end_valid.
2721 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2722 (Fwindow_line_height, set_window_buffer, Frecenter)
2723 (Fsplit_window_internal, Fdelete_other_windows_internal)
2724 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2725 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2726 * xdisp.c (check_window_end, reconsider_clip_changes)
2727 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2728 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2729 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2731 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2733 * xdisp.c (mark_window_display_accurate): Simplify the loop
2734 assuming that the only one of vchild, hchild or buffer window
2735 slots is non-nil. Call mark_window_display_accurate_1 for
2736 the leaf windows only.
2737 (mark_window_display_accurate_1): Always assume leaf window.
2740 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2742 * emacs.c (Qkill_emacs_hook): Now static.
2744 * fileio.c (Finsert_file_contents): Simplify.
2745 Remove unnecessary assignments and tests.
2747 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2749 * w32.c (acl_set_file): Don't test for errors unless
2750 set_file_security returns FALSE. Avoids spurious errors when
2753 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2755 * fileio.c (Finsert_file_contents): Revert code introduced at
2756 2013-01-18 in favor of the simpler and generally better fix.
2757 Save stack space by removing 'buffer' and reusing 'read_buf'
2760 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2762 * lisp.h (eabs): Define unconditionally (Bug#13419).
2763 The old "#if !defined (eabs)" was an unnecessary revenant of back
2764 when this macro was called "abs". Document 'eabs' better.
2766 2013-01-19 Glenn Morris <rgm@gnu.org>
2768 * fns.c (Frandom): Doc fix.
2770 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2772 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2773 segfault when there are lots of overlays.
2775 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2776 when there are lots of overlays.
2777 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2778 for the details and a way to reproduce.
2780 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2782 * fileio.c: Use O_APPEND to append.
2783 This corresponds better to the natural interpretation of "append",
2784 and avoids the need to open the output file twice, or to invoke
2785 lseek when APPEND is neither nil nor a number.
2786 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2787 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2788 file possibly twice, and lseeking to its end; this avoids the
2789 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2790 at the same time: the combination is never needed and apparently
2791 it doesn't work with DOS_NT.
2793 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2794 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2796 Allow floating-point file offsets.
2797 Problem reported by Vitalie Spinu in
2798 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2799 * fileio.c (emacs_lseek): Remove.
2800 (file_offset): New function.
2801 (Finsert_file_contents, Fwrite_region): Use it.
2803 2013-01-19 Chong Yidong <cyd@gnu.org>
2805 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2806 aborting on Fsignal (Bug#13289).
2808 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2810 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2811 set_file_security as failure due to insufficient privileges.
2812 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2813 (fstat): Return owner and group like 'stat' and 'lstat' do.
2815 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2817 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2818 The bug was observed on Ubuntu operating inside a virtual machine,
2819 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2820 The workaround introduces a race condition on non-buggy hosts,
2821 but it's an unlikely race and anyway there's a nearly identical
2822 nearby race that can't be fixed.
2823 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2825 (Fwrite_region): Test for file system time stamp bug.
2826 (init_fileio): New function.
2827 * lisp.h (init_fileio): Declare it.
2828 * emacs.c (main): Call it.

2836 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2837 for the error description produced by valgrind.
2838 * fileio.c (read_non_regular): Rename to read_contents.
2839 Free Lisp_Save_Value object used to pass parameters.
2840 (read_non_regular_quit): Rename to read_contents_quit.
2841 (Finsert_file_contents): Redesign internal file reading loop to adjust
2842 gap and end positions after each read and so help make_gap to work
2843 properly. Do not signal an I/O error too early and so do not leave
2844 not yet decoded characters in a buffer, which was the reason of
2845 redisplay crash. Use list2 to build return value. Adjust comments.
2847 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2849 Close a race when statting and reading files (Bug#13149).
2850 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2851 This avoids a race if the file is renamed between stat and open.
2852 This race is not the problem originally noted in Bug#13149;
2853 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

2898 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2899 extraction from any Lisp_Save_Value slot. Add type checking.

2952 * editfns.c (save_excursion_save): Pack everything within
2953 Lisp_Save_Value and so avoid xmalloc.
2954 (save_excursion_restore): Adjust to match new layout. Use free_misc
2955 because we do not allocate extra memory any more. Add eassert.
2956 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2957 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2971 Fix SIGDANGER handlers, for AIX (Bug#13408).
2972 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

3046 which has already arranged for that.
3047 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

3120 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3121 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3122 digits for buffer positions, before misalignment starts.

3242 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3243 don't ENCODE_FILE them, and return a unibyte string if the input
3245 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3246 don't assume the input strings will always be multibyte. If the
3247 input strings are multibyte, decode strings obtained from C
3250 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3252 * lisp.h (toplevel): Add two notices to the comment about
3253 defining a new Lisp data type.
3254 * print.c (print_object): If Lisp_Save_Value object's pointer
3255 is the address of a memory area containing Lisp_Objects, try
3257 * alloc.c (valid_lisp_object_p): Adjust comment.
3259 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3261 * keyboard.c (record_asynch_buffer_change): Initialize an event
3262 only if it's really needed.
3263 * frame.h (enum output_method): Remove output_mac member since
3264 it's a leftover from the deleted code.
3265 * frame.c (Fframep): Adjust user here ...
3266 * terminal.c (Fterminal_live_p): ... and here.
3267 * coding.c (Qmac): Now here because it's only used to denote
3268 end-of-line encoding type.
3269 (syms_of_coding): DEFSYM it.
3270 * frame.h (Qmac): Remove duplicated declaration.
3272 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3274 * window.c (select_window_1): Now static, since it's used only here.
3276 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3278 * window.c (window_body_cols): Subtract display margins from the
3279 window body width on TTYs as well. See
3280 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3281 for the original report.
3283 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3285 * xdisp.c (redisplay_window): Remove inner local variable
3286 because the outer shadowed one has the same meaning.
3287 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3289 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3290 (xg_create_tool_bar): Adjust users.
3292 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3294 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3295 * buffer.c (Fget_buffer_create): Use it to set compact field of
3296 struct buffer_text to avoid accessing an uninitialized value
3297 when compact_buffer is called for the first time.
3298 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3299 (Fset_buffer_modified_p): Use buffer_window_count to check
3300 whether the buffer is displayed in some window.
3301 * xdisp.c (message_dolog): Likewise.
3303 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3305 * w32.c (acl_set_file): If setting the file security descriptor
3306 fails, and the new DACL is identical to the existing one, silently
3307 return success. This fixes problems for users backing up their
3308 own files without having the necessary privileges for setting
3309 security descriptors.
3311 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3313 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3314 after WaitForSingleObject returns normally. This expedites reader
3315 thread shutdown when delete_child triggers it.
3316 (reap_subprocess): More accurate commentary for why we call
3317 delete_child only when cp->fd is negative.
3319 * w32.c (sys_close): Do not call delete_child on a subprocess
3320 whose handle is not yet closed. Instead, set its file descriptor
3321 to a negative value, so that reap_subprocess will call
3322 delete_child on that subprocess when its SIGCHLD arrives.
3323 This avoids closing handles used for communications between sys_select
3324 and reader_thread, which doesn't give sys_select a chance to
3325 notice that the process exited and invoke the SIGCHLD handler for
3328 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3330 * nsfns.m (Fns_do_applescript): Run event loop until script has
3331 been executed (Bug#12969).
3332 (ns_run_ascript): Chech as_script for nil, set to nil after
3335 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3337 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3339 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3341 * w32term.c (w32fullscreen_hook): New function.
3342 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3344 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3346 * fileio.c (Finsert_file_contents): Doc fix.
3348 * w32proc.c (new_child, delete_child, find_child_pid): For a
3349 subprocess, consider its slot being in use as long as its process
3350 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3351 slot when a new process is started immediately after killing
3352 another one, without waiting enough time for the first process to
3353 be reaped and resources allocated for it be orderly freed.
3355 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3357 2012-12-21 Chong Yidong <cyd@gnu.org>
3359 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3361 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3363 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3365 * w32.c (get_name_and_id): Always pass NULL as the first argument
3366 of lookup_account_sid. Avoids crashes with UNC file names that
3367 refer to DFS domains, not to specific machine names. (Bug#12621)
3368 Remove now unused argument FNAME; all callers changed.
3369 (get_file_owner_and_group): Remove now unused argument FNAME; all
3372 2012-12-21 Chong Yidong <cyd@gnu.org>
3374 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3375 error for invalid chars, don't check for a nil return value.
3377 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3379 Avoid calls to CHAR_TO_BYTE if byte position is known.
3380 * editfns.c (make_buffer_string_both): Use move_gap_both.
3381 (Fbuffer_string): Use make_buffer_string_both.
3382 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3384 (buf_bytepos_to_charpos): Likewise.
3385 (charpos_to_bytepos): Remove.
3386 * fileio.c (Finsert_file_contents): Use move_gap_both.
3387 * search.c (Freplace_match): Likewise.
3388 * process.c (process_send_region): Likewise. Use convenient
3389 names for byte positions.
3390 * lisp.h (charpos_to_bytepos): Remove prototype.
3391 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3392 * insdel.c (move_gap): Likewise.
3394 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3396 * xdisp.c (redisplay_internal): Remove now-unused local.
3398 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3400 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3401 (redisplay_internal): Don't bother selecting the frame to get the
3402 proper value of frame-local variables (bug#13225).
3404 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3406 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3407 Rename 4th argument since it may be buffer or string. Adjust comment.
3408 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3410 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3412 * coding.c (Fdetect_coding_region): Do not check start and end with
3413 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3414 (code_convert_region): Likewise.
3416 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3418 * w32.c (acl_get_file, acl_set_file): Run the file name through
3419 map_w32_filename, and resolve any symlinks in the file name, like
3421 (acl_set_file): Call revert_to_self, if any privileges were
3424 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3426 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3427 ($(BLD)/w32.$(O)): Update dependencies.
3429 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3431 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3432 propagate redisplay's scrolling (if any) to the right window.
3433 (redisplay_internal): Use ensure_selected_frame.
3434 (display_mode_lines): Complete last fix.
3435 * window.c (select_window_1): New func, extracted from select_window.
3436 (select_window): Use it.
3437 * window.h (select_window_1): Declare.
3439 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3441 Emulate Posix ACL APIs on MS-Windows.
3442 * w32.c: Include sddl.h and sys/acl.h.
3443 (SDDL_REVISION_1): Define if not already defined.
3444 (g_b_init_get_security_descriptor_dacl)
3445 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3446 (g_b_init_is_valid_security_descriptor)
3447 (g_b_init_set_file_security): New static flags.

3459 (acl_free, acl_get_file, acl_set_file): New functions.
3461 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3463 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3465 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3466 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3467 for some of that bug's symptoms can now cause Emacs to abort.
3468 Remove the workaround.
3469 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3470 The bug that caused SIGCHLD to get lost has been fixed, and the
3471 workaround for it can now cause Emacs to abort.
3473 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3475 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3476 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3477 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3479 2012-12-16 Romain Francoise <romain@orebokech.com>
3481 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3482 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3483 and copy ACL entries of file in addition to SELinux context if set.
3484 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3486 * Makefile.in (LIBACL_LIBS): New macro.
3489 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3491 * fileio.c (internal_delete_file): Use bool for boolean.
3493 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3495 Fix bug #13079 on MS-Windows with temp files not being deleted.

3498 (register_child): First argument is now pid_t.
3499 (record_infile, record_pending_deletion): New prototypes.
3501 * w32proc.c (new_child): Initialize input_file and
3502 pending_deletion members of the child.
3503 (delete_child): Delete the child's temporary input file, if any,
3504 that is pending deletion.
3505 (register_child): First argument is now pid_t.
3506 (record_infile, record_pending_deletion): New functions.
3507 (reap_subprocess): Fix a typo in DebPrint string.
3508 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3510 * fileio.c (internal_delete_file): Return an int again: non-zero
3511 if delete-file succeeds, zero otherwise.
3513 * lisp.h (internal_delete_file): Adjust prototype.
3515 * callproc.c (Fcall_process): Don't overwrite infile with result
3517 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3518 asynchronous subprocess, record the name of the input file name,
3520 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3521 delete the file, record it as pending deletion when the subprocess
3524 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3526 * editfns.c [HAVE_PWD_H]: Include grp.h.
3528 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3530 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3532 Fix permissions bugs with setgid directories etc. (Bug#13125)
3533 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3534 to mark it as a placeholder. The old value was often wrong.
3535 The only user of this attribute has been changed to use
3536 file-ownership-preserved-p instead, with its new group arg.
3537 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3539 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

3544 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3546 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3547 try to get accurate owner and group information from NT file
3548 security APIs. This is to make most callers of 'stat' and
3549 'lstat', which don't need that information, much faster.
3551 * dired.c (Ffile_attributes) [WINDOWSNT]:
3552 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3553 owner and group information from 'lstat'.
3555 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3557 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3558 as that confuses set-auto-coding, so insist on the head-read
3559 returning the full 1024 bytes. Let lseek compute the tail offset;
3560 less work for us. Do not ignore I/O errors when reading the tail.
3562 * xdisp.c: Minor style fixes.
3563 (init_iterator): Hoist assignment out of if-expression.
3564 (markpos_of_region): Callers now test for sign, not for -1.
3566 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3568 Minor redisplay optimization when the region length is zero.
3569 * xdisp.c (markpos_of_region): New function.
3570 (init_iterator): Do not highlight the region of zero length.
3571 (redisplay_window): Check whether the region is of non-zero length.
3572 (try_cursor_movement): Allow if the region length is zero.
3573 (try_window_reusing_current_matrix, try_window_id): Likewise.
3575 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3577 * search.c (search_buffer): Check the inverse translations of each
3578 character in pattern when the buffer being searched is unibyte.
3581 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3583 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3584 files, fixing a regression from 24.2.
3585 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3587 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3589 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3590 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3591 Remove unnecessary S_ISLNK test, as (contra the comments) this
3592 function can't copy symlinks. Improve quality of error message
3593 when attempting to copy files that are neither regular files nor

3601 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3602 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3604 2012-12-12 Daniel Colascione <dancol@dancol.org>
3606 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3607 the dumped Emacs is not a sparse file, greatly improving Cygwin
3608 "make bootstrap" performance.
3610 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3612 * inotify.c (inotify_callback): Generate an Emacs event for every
3613 incoming inotify event.
3615 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3617 * xdisp.c (handle_face_prop): Fix logic of computing
3618 it->start_of_box_run_p.
3619 (append_space_for_newline): If the glyph row is R2L, reset the
3620 iterator's end_of_box_run_p flag before prepending the space glyph.
3621 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3622 iterator's start_of_box_run_p flag before prepending the stretch.
3623 (append_glyph, produce_image_glyph, append_composite_glyph)
3624 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3625 left_box_line_p and right_box_line_p flags of the glyph for R2L
3626 glyph rows. (Bug#13011)
3628 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3630 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
3631 if changed buffer is not shown in a window.
3632 * insdel.c (prepare_to_modify_buffer): Likewise.
3633 * window.c (replace_buffer_in_windows_safely): Do nothing
3634 if buffer is not shown in a window.

3638 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3640 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3641 encoded_file_name, which is what it is.
3643 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3645 Consistently use marker_position and marker_byte_position.
3646 * fringe.c (Ffringe_bitmaps_at_pos):
3647 * indent.c (Fvertical_motion):
3648 * insdel.c (prepare_to_modify_buffer):

3653 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
3654 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
3655 Replace direct access to marker fields with calls
3656 to marker_position and/or marker_byte_position.
3658 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
3660 * makefile.w32-in (SIG2STR_H): New macro.
3661 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
3662 ($(BLD)/w32notify.$(O)): Update dependencies.
3664 2012-12-10 Daniel Colascione <dancol@dancol.org>

3667 Windows file notification functionality unless WINDOWSNT.
3669 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3672 * w32fns.c (cache_system_info): Initialize the global hinst
3673 variable here so various initialization calls DTRT.
3675 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3676 (hinst): Remove unneeded extern declaration.
3677 (_start): Remove initialization of above variables; remove
3678 initialization of hinst, as cache_system_info now does that.
3680 * emacs.c (main): Call cache_system_info early in startup; we
3681 previously weren't calling it in Cygwin builds.
3683 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
3684 Teach the autoconf build system how to compile a Windows resource file
3685 and link it to Emacs.

3698 and buffer_local_symbols.
3699 * window.h (buffer_shared): Remove declaration.
3700 (wset_buffer): Convert from inline ...
3701 * window.c (wset_buffer): ... to an ordinary function.
3702 (adjust_window_count): New function.
3703 (make_parent_window): Use it.

3712 and this is a TTY frame, signal the caller that keyboard input is
3715 * w32xfns.c (drain_message_queue): Now returns an int: an

3820 * w32.c (unsetenv): Return 0 if the input string is too long.
3822 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3824 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3825 * alloc.c (xputenv): New function.
3826 * dbusbind.c (Fdbus_init_bus):
3828 * xterm.c (x_term_init):

3839 no longer needed here.
3840 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3841 Move to inside set_time_zone_rule; they don't need file scope any more.
3842 (set_time_zone_rule): Maintain the TZ=value string separately.
3843 (syms_of_editfns): Don't initialize initial_tz;
3844 init_editfns now does it.
3845 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.

3861 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3863 Simplify get_lim_data.
3864 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3865 Remove USG and vlimit methods; no longer used these days.
3866 Add #error catchall just in case.
3868 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3869 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3870 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

3892 This will cause a production Emacs to dump core instead of
3895 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3897 * frame.c (make_frame): Do not set window's buffer to t.
3898 * window.c (Fsplit_window_internal): Likewise. Previously it was
3899 used to indicate that the window is being set up. Now we use
3900 set_window_buffer for all new windows, so the condition in ...
3901 (Fset_window_buffer): ... is always true and can be removed.
3903 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3905 Convenient macro to check whether the buffer is hidden.
3906 * buffer.h (BUFFER_HIDDEN_P): New macro.
3907 * frame.c (make_frame): Use it. Adjust comment.
3908 * buffer.c (candidate_buffer): New function.
3909 (Fother_buffer, other_buffer_safely): Use it.
3911 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3913 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG

3915 loop and return zero. (Bug#13086)
3917 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3919 * frame.h (x_char_width, x_char_height): Remove prototypes.

3933 * callproc.c, process.h (record_kill_process):
3934 New function, containing part of the old call_process_kill.
3935 (call_process_kill): Use it.
3936 This does not change call_process_kill's behavior.
3937 * process.c (Fdelete_process): Use record_kill_process to fix a
3938 race condition that could cause Emacs to lose track of a child.
3940 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3942 Avoid code duplication between prev_frame and next_frame.
3943 * frame.c (candidate_frame): New function. Add comment.
3944 (prev_frame, next_frame): Use it. Adjust comment.
3946 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3948 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3949 fails, signal an error instead of continuing with an empty
3951 Encode expanded temp file pattern before passing it to mkstemp or
3954 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3955 Encode the file name before passing it to dostounix_filename, in
3956 case it will downcase it (under w32-downcase-file-names).
3959 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3961 Minor call-process cleanups.
3962 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3963 at the same time as other platforms, to simplify analysis.
3964 No need for fd0_volatile since we have synch_process_fd.
3965 Avoid needless emacs_close; arg is always negative.
3967 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3969 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3972 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3974 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3975 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3976 and mouse_face_hidden members to a bitfields.
3977 * frame.h (struct frame): Remove set-but-not-used space_width member.
3978 (FRAME_SPACE_WIDTH): Remove.
3979 * nsterm.m, w32term.c, xterm.c: Adjust users.
3980 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3981 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3982 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3983 members to a bitfields.
3985 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3987 Don't let call-process be a zombie factory (Bug#12980).
3988 Fixing this bug required some cleanup of the signal-handling code.
3989 As a side effect, this change also fixes a longstanding rare race
3990 condition whereby Emacs could mistakenly kill unrelated processes,
3991 and it fixes a bug where a second C-g does not kill a recalcitrant
3992 synchronous process in GNU/Linux and similar platforms.
3993 The patch should also fix the last vestiges of Bug#9488,
3994 a bug which has mostly been fixed on the trunk by other changes.
3995 * callproc.c, process.h (synch_process_alive, synch_process_death)
3996 (synch_process_termsig, sync_process_retcode):
3997 Remove. All uses removed, to simplify analysis and so that
3998 less consing is done inside critical sections.
3999 * callproc.c (call_process_exited): Remove. All uses replaced
4000 with !synch_process_pid.
4001 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4002 These take the role of what used to be in unwind-protect arg.
4004 (block_child_signal, unblock_child_signal):
4005 New functions, to avoid races that could kill innocent-victim processes.
4006 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4007 (call_process_kill): Record killed processes as deleted, so that
4008 zombies do not clutter up the system. Do this inside a critical
4009 section, to avoid a race that would allow the clutter.
4010 (call_process_cleanup): Fix code so that the second C-g works again
4011 on common platforms such as GNU/Linux.
4012 (Fcall_process): Create the child process in a critical section,
4013 to fix a race condition. If creating an asynchronous process,
4014 record it as deleted so that zombies do not clutter up the system.
4015 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4016 light of these changes. Omit unnecessary call to emacs_close
4017 before failure, as the unwind-protect code does that.
4018 * callproc.c (call_process_cleanup):
4019 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4020 * process.c (record_deleted_pid): New function, containing
4021 code refactored out of Fdelete_process.
4022 (Fdelete_process): Use it.
4023 (process_status_retrieved): Remove. All callers changed to use
4024 child_status_change.
4025 (record_child_status_change): Remove, folding its contents into ...
4026 (handle_child_signal): ... this signal handler. Now, this
4027 function is purely a handler for SIGCHLD, and is not called after
4028 a synchronous waitpid returns; the synchronous code is moved to
4029 wait_for_termination. There is no need to worry about reaping
4030 more than one child now.
4031 * sysdep.c (get_child_status, child_status_changed): New functions.
4032 (wait_for_termination): Now takes int * status and bool
4033 interruptible arguments, too. Do not record child status change;
4034 that's now the caller's responsibility. All callers changed.
4035 Reimplement in terms of get_child_status.
4036 (wait_for_termination_1, interruptible_wait_for_termination):
4037 Remove. All callers changed to use wait_for_termination.
4038 * syswait.h: Include <stdbool.h>, for bool.
4039 (record_child_status_change, interruptible_wait_for_termination):
4041 (record_deleted_pid, child_status_changed): New decls.
4042 (wait_for_termination): Adjust to API changes noted above.
4044 * bytecode.c, lisp.h (Qbytecode): Remove.
4045 No longer needed after 2012-11-20 interactive-p changes.
4047 2012-12-03 Eli Zaretskii <eliz@gnu.org>
4049 * xdisp.c (redisplay_window): If the cursor is visible, but inside
4050 the scroll margin, move point outside the margin. (Bug#13055)
4052 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
4054 * gtkutil.c (my_log_handler): New function.
4055 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4057 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4059 * lisp.h (modify_region): Rename to...
4060 (modify_region_1): ...new prototype.
4061 * textprop.c (modify_region): Now static. Adjust users.
4062 * insdel.c (modify_region): Rename to...
4063 (modify_region_1): ...new function to work with current buffer.
4064 Adjust comment and users. Use true and false for booleans.
4066 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4068 * alloc.c (free_save_value): New function.
4069 (safe_alloca_unwind): Use it.
4070 * lisp.h (free_save_value): New prototype.
4071 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4073 (save_excursion_restore): Adjust to match saved data structure.
4074 Use free_save_value to offload some work from GC. Drop obsolete
4077 2012-12-03 Chong Yidong <cyd@gnu.org>
4079 * fileio.c (Vauto_save_list_file_name): Doc fix.
4081 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4083 * w32fns.c: Remove prototype of atof.
4084 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
4086 (file_dialog_callback): Make it UINT_PTR.
4088 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
4091 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4092 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
4095 2012-12-03 Glenn Morris <rgm@gnu.org>
4097 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
4099 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
4101 Fix xpalloc confusion after memory is exhausted.
4102 * alloc.c (xpalloc): Comment fix.
4103 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4104 and signals an error, do not clear charset_table_size, as
4105 charset_table is still valid.
4106 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4108 Use execve to avoid need to munge environ (Bug#13054).
4109 * callproc.c (Fcall_process):
4110 * process.c (create_process):
4111 Don't save and restore environ; no longer needed.
4112 * callproc.c (child_setup):
4113 Use execve, not execvp, to preserve environ.
4115 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4117 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
4119 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4121 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
4122 display for sliced images (Bug#10500).

4126 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
4128 * doc.c (Fdocumentation): Re-add handling of function-documentation,
4129 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4131 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4133 * xdisp.c (window_outdated): Remove eassert since it hits
4134 some suspicious corner cases (see Bug#13007 and Bug#13012).
4135 (mode_line_update_needed): New function.
4136 (redisplay_internal, redisplay_window): Use it.

4140 (buffer_shared_and_changed): ...near to its real use.
4142 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
4144 * callproc.c (Fcall_process): Don't misreport vfork failure.
4146 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4148 * callproc.c (Fcall_process): Fix vfork portability problems.
4149 Do not assume that fd[0], count, filefd, and save_environ survive
4150 vfork. Fix bug whereby wrong errno value could be reported for
4151 pipe failure. Some minor cleanups, too, as follows. Move buf and
4152 bufsize to the context where they're needed. Change new_argv to
4153 be of type char **, as this is more convenient and avoids casts.
4154 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4155 Now local constants, not macros.
4157 2012-11-18 Kenichi Handa <handa@gnu.org>

4183 * unexcoff.c (write_segment): Assume EFAULT is defined.
4185 2012-11-27 Eli Zaretskii <eliz@gnu.org>
4187 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
4190 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
4191 highlighting on the frame was cleared. Prevents assertion
4192 violations when repeatedly clicking on the "Top" link of the
4193 "bread-crumbs" in Info buffers.
4195 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
4197 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
4199 2012-11-24 Ken Brown <kbrown@cornell.edu>
4201 * keyboard.c (HAVE_MOUSE):
4202 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
4203 were always defined.
4205 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4207 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4208 between bpos_covered and bpos_max. This fixes cursor display when
4209 several display strings follow each other.
4211 * .gdbinit (pgx): If the glyph's object is a string, display the
4212 pointer to string data, rather than the value of the string object
4213 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4215 * indent.c (Fvertical_motion): If the starting position is covered
4216 by a display string, return to one position before that, to avoid
4217 overshooting it inside move_it_to. (Bug#12930)
4219 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4221 * frame.h (struct frame): Remove display_preempted member
4222 since all users are dead long ago.
4223 * nsterm.h (struct x_output): Use the only dummy member.
4224 * w32menu.c (pending_menu_activation): Remove since not
4226 (set_frame_menubar): Adjust user.
4227 * w32term.h (struct x_output): Drop outdated #if 0 code.
4228 (struct w32_output): Use bitfields for explicit_parent,
4229 asked_for_visible and menubar_active members.
4230 Drop unused pending_menu_activation member.
4231 * xterm.h (struct x_output): Drop outdated #if 0 code.
4232 Use bitfields for explicit_parent, asked_for_visible,
4233 has_been_visible and net_wm_state_hidden_seen members.
4235 2012-11-23 Eli Zaretskii <eliz@gnu.org>
4237 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4238 of a literal "/". (Bug#12955)
4239 (gl-stamp): Invoke fc.exe directly, not through cmd.
4241 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4243 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4244 * dired.c: Assume HAVE_DIRENT_H.
4245 (NAMLEN): Remove, replacing with ...
4246 (dirent_namelen): New function. All uses changed. Use the GNU macro
4247 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4248 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4249 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4250 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4252 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4253 * ndir.h: Rename to ../nt/inc/dirent.h.
4254 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4255 Do not include <dirent.h>; no longer needed.
4256 * w32.c: Include <dirent.h> rather than "ndir.h".
4258 2012-11-23 Chong Yidong <cyd@gnu.org>
4260 * xftfont.c (xftfont_open): Remove duplicate assignment.
4262 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4264 * alloc.c (Fgarbage_collect): Unblock input after clearing
4265 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4266 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4267 * msdos.c (IT_frame_up_to_date): Use it here...
4268 * w32term.c (w32_frame_up_to_date): ...here...
4269 * xterm.c (XTframe_up_to_date): ...and here...
4270 * nsterm.m (ns_frame_up_to_date): ...but not here.
4271 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4273 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4274 Do not check whether GC is in progress.
4276 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4278 * xdisp.c (window_buffer_changed): New function.
4279 (update_menu_bar, update_tool_bar): Use it to
4280 simplify large 'if' statements.
4281 (redisplay_internal): Generalize commonly used
4282 'tail' and 'frame' local variables.
4284 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4286 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4287 with Windows system header.
4289 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4291 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4292 * alloc.c: Assume unistd.h exists.
4293 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4294 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4295 (getwd) [USG]: Remove; no longer needed.
4296 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4297 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4298 * w32.h (getcwd): Remove decl.
4300 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4302 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4303 Make it set selected_window as well.
4304 (update_tool_bar): Use it.
4306 2012-11-21 Ken Brown <kbrown@cornell.edu>
4308 * emacs.c (main): Set the G_SLICE environment variable for all
4309 Cygwin builds, not just GTK builds. See
4310 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4312 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4314 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4315 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4316 Define for the MSVC compiler.
4318 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4320 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4321 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4322 dostounix_filename. Prevents crashes down the road, because
4323 dostounix_filename assumes it gets a unibyte string.
4324 Reported by Michel de Ruiter <michel@sentient.nl>, see
4325 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
4327 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4329 Conflate Qnil and Qunbound for `symbol-function'.
4330 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
4331 * lread.c (init_obarray): Set `function' fields to Qnil.
4332 * eval.c (Fcommandp): Ignore Qunbound.
4333 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
4334 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
4335 Test NILP rather than Qunbound.
4336 (Ffmakunbound): Set to Qnil.
4337 (Fsymbol_function): Never signal an error.
4338 (Finteractive_form): Ignore Qunbound.
4340 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
4342 * eval.c (interactive_p): Remove no-longer-used decl.
4344 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4346 * xdisp.c (buffer_shared): Adjust comment.
4347 (buffer_shared_and_changed): New function.
4348 (prepare_menu_bars, redisplay_internal): Use it to
4349 decide whether all windows or frames should be updated.
4350 (window_outdated): New function.
4351 (text_outside_line_unchanged_p, redisplay_window): Use it.
4352 (redisplay_internal): Likewise. Fix indentation.
4354 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4356 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4357 (syms_of_eval): Remove corresponding defsubr.
4358 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4360 2012-11-19 Daniel Colascione <dancol@dancol.org>
4362 * w32fns.c (Fx_file_dialog):
4363 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4364 cygwin_convert_file_name*.
4366 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4367 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4369 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4371 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4373 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4375 * w32select.c: Include w32common.h before w32term.h, so that
4376 windows.h gets included before w32term.h uses some of its
4377 features, see below.
4379 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4381 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4383 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4385 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4387 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4388 (ns_select): Return at once if events are held (Bug#12834).
4390 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4392 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4393 Needed following 2012-10-20 change. (Bug#12902)
4395 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4397 * w32proc.c (waitpid): Remove unused label get_result.
4399 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4401 * makefile.w32-in (SYSWAIT_H): New macro.
4402 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4403 ($(BLD)/sysdep.$(O)): Update dependencies.
4405 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4407 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4408 * callproc.c (relocate_fd): Assume F_DUPFD.
4409 * emacs.c, term.c (O_RDWR): Remove.
4410 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4411 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4412 * nsterm.m: Assume <fcntl.h> exists.
4413 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4414 (create_pty, Fmake_network_process, server_accept_connection)
4415 (wait_reading_process_output, init_process_emacs):
4417 (wait_reading_process_output): Put in a special case for WINDOWSNT
4418 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4419 It's not clear this is needed, but it's a more-conservative change.
4420 (create_process): Assume FD_CLOEXEC.
4421 (create_process, create_pty): Assume O_NOCTTY.
4422 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4423 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4424 Omit if not DOS_NT, since F_GETFL is not defined there.
4425 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4426 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4428 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4429 lack it, since gnulib guarantees this.
4430 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4432 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4434 * w32.c (faccessat): Pretend that directories have the execute bit
4435 set. Emacs expects that, e.g., in files.el:cd-absolute.
4437 * w32proc.c (create_child): Don't clip the PID of the child
4438 process to fit into an Emacs integer, as this is no longer a
4440 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4441 reaping only the process specified by PID argument, if that is
4442 positive. Use PID instead of dead_child to know which process to
4443 reap. Wait for the child to die only if WNOHANG is not in
4445 (sys_select): Don't set dead_child.
4447 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4448 as it is no longer needed.
4450 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4452 (record_child_status_change): Remove the setting of
4453 record_at_most_one_child for the !WNOHANG case.
4455 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4457 Fix problems in ns port found by static checking.
4458 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4459 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4460 not to process group.
4461 (ns_select): Use emacs_write, not write, as that's more robust
4462 in the presence of signals.
4463 (fd_handler:): Check for read errors.
4465 2012-11-16 Glenn Morris <rgm@gnu.org>
4467 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4469 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4471 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4473 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4475 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4476 use the same value of thread handle.
4477 (start_timer_thread): If the timer thread exited (due to error),
4478 clean up by closing the two handles it used. Duplicate the caller
4479 thread's handle here, so it gets duplicated only once, when
4480 launching the timer thread. Set priority of the timer thread, not
4482 (getitimer): Don't duplicate the caller thread's handle here.
4485 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4487 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4490 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4492 Remove no-longer-used pty_max_bytes variable.
4493 * process.c (pty_max_bytes): Remove; unused.
4494 (send_process): Do not set it.
4496 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4498 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4499 Update dependencies.
4501 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4503 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4504 This follows up on the 2012-09-29 patch that removed indirection
4505 for the 'function' field. Reported by Sergey Vinokurov in
4506 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4508 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4510 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4511 different name, as the MS runtime does not have such a function,
4512 and probably never will.) All callers changed. Ignore DIRFD
4513 value if PATH is an absolute file name, to match Posix spec
4514 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4517 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4519 * xdisp.c (echo_area_display, redisplay_internal):
4520 Omit redundant check whether frame_garbaged is set.
4522 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4524 Use faccessat, not access, when checking file permissions (Bug#12632).
4525 This fixes a bug that has been present in Emacs since its creation.
4526 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4527 which must set some sort of record. (Torek's bug report was against
4528 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4529 same common flaw.) See Torek's Usenet posting
4530 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4531 Posted: Fri Apr 8 14:18:56 1983.
4532 * Makefile.in (LIB_EACCESS): New macro.
4534 * callproc.c (init_callproc):
4535 * charset.c (init_charset):
4536 * fileio.c (check_existing, check_executable, check_writable)
4538 * lread.c (openp, load_path_check):
4539 * process.c (allocate_pty):
4541 Use effective UID when checking permissions, not real UID.
4542 * callproc.c (init_callproc):
4543 * charset.c (init_charset):
4544 * lread.c (load_path_check, init_lread):
4545 Test whether directories are accessible, not merely whether they exist.
4546 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4547 * fileio.c (check_existing, check_executable, check_writable)
4549 Use symbolic names instead of integers for the flags, as they're
4551 (check_writable): New arg AMODE. All uses changed.
4552 Set errno on failure.
4553 (Ffile_readable_p): Use faccessat, not stat + open + close.
4554 (Ffile_writable_p): No need to call check_existing + check_writable.
4555 Just call check_writable and then look at errno. This saves a syscall.
4556 dir should never be nil; replace an unnecessary runtime check
4557 with an eassert. When checking the parent directory of a nonexistent
4558 file, check that the directory is searchable as well as writable, as
4559 we can't create files in unsearchable directories.
4560 (file_directory_p): New function, which uses 'stat' on most platforms
4561 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4562 (Ffile_directory_p, Fset_file_times): Use it.
4563 (file_accessible_directory_p): New function, which uses a single
4564 syscall for efficiency.
4565 (Ffile_accessible_directory_p): Use it.
4566 * xrdb.c (file_p): Use file_directory_p.
4567 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4568 * lread.c (openp): When opening a file, use fstat rather than
4569 stat, as that avoids a permissions race. When not opening a file,
4570 use file_directory_p rather than stat.
4571 (dir_warning): First arg is now a usage string, not a format.
4572 Use errno. All uses changed.
4573 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4574 that merely introduced a race.
4575 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4576 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4577 and similarly for the other O_* flags.
4578 * w32.c (sys_faccessat): Rename from sys_access and switch to
4579 faccessat's API. All uses changed.
4580 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4581 (magic_db): Rename from magic_file_p.
4582 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4583 char *, so that we don't have to test for file existence
4584 separately from opening the file for reading. This removes a race
4585 fixes a permission-checking problem, and simplifies the code.
4587 (file_p): Remove; no longer needed.
4589 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4591 Omit glyphs initialization at startup.
4592 * dispnew.c (glyphs_initialized_initially_p): Remove.
4593 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4594 (Fredraw_frame): Move actual code from here...
4595 (redraw_frame): ...to here. Add eassert. Adjust comment.
4596 (Fredraw_display): Use redraw_frame.
4597 * xdisp.c (clear_garbaged_frames): Likewise.
4599 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4601 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4602 passed to pint2str and pint2hrstr to be at most the size of the
4603 frame's decode_mode_spec_buffer. This avoids crashes with very
4604 large values of FIELD_WIDTH argument to decode_mode_spec.
4607 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4609 Fix a race with verify-visited-file-modtime (Bug#12863).
4610 Since at least 1991 Emacs has ignored an mtime difference of no
4611 more than one second, but my guess is that this was to work around
4612 file system bugs that were fixed long ago. Since the race is
4613 causing problems now, let's remove that code.
4614 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4615 whose time stamp is off by no more than a second. Insist that the
4616 file time stamps match exactly.
4618 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4620 * frame.h (struct frame): Convert external_tool_bar member to
4621 1-bit unsigned bitfield.
4622 * termhooks.h (struct terminal): Remove mouse_moved member since
4623 all users are long dead. Adjust comment on mouse_position_hook.
4625 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4627 Simplify by using FOR_EACH_FRAME here and there.
4628 * frame.c (next_frame, prev_frame, other_visible_frames)
4629 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4630 * w32term.c (x_window_to_scroll_bar): Likewise.
4631 * window.c (window_list): Likewise.
4632 * xdisp.c (x_consider_frame_title): Likewise.

4642 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4644 * data.c (Qdefalias_fset_function): Now static.
4646 Another tweak to vectorlike_header change.

4649 (next_in_free_list, set_next_in_free_list):
4650 New functions, which respect C's aliasing rules better.
4652 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4654 * window.c (list4i): Rename from 'quad'. All uses changed.
4655 Needed because <sys/types.h> defines 'quad' on Solaris 10.

4669 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4671 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4672 amount when the scroll margins are too large. When scrolling
4673 backwards in the buffer, give up if cannot reach point or the
4674 scroll margin within a reasonable number of screen lines.
4675 Fixes point position in window under scroll-up/down-aggressively when
4676 point is positioned many lines beyond the window top/bottom.
4679 * ralloc.c (relinquish): If real_morecore fails to return memory
4680 to the system, don't crash; instead, leave the last heap
4681 unchanged and return. (Bug#12774)

4702 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4704 Fix recently introduced crash on MS-Windows (Bug#12839).
4705 * w32term.h (struct scroll_bar): Use convenient header.
4706 (SCROLL_BAR_VEC_SIZE): Remove.
4707 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4709 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4711 Tweak last vectorlike_header change.
4712 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4713 vectorlike object on the free list. This is introduced to avoid
4714 some (but not all) pointer casting and aliasing problems, see
4715 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4716 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4720 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4722 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

4727 * doc.c (Fdocumentation): Handle new property
4728 dynamic-docstring-function to replace the old ad-advice-info.

4734 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4736 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4737 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4738 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

4745 * lisp.h (sxhash_combine): New inline function, with the contents
4746 of the old SXHASH_COMBINE.

4748 special hash function containing a comparison that always yields 1.
4750 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4752 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4753 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4754 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4757 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4759 * image.c (xpm_make_color_table_h): Fix compiler error because
4760 make_hash_table changed.
4762 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4764 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4766 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4768 Use ad-hoc comparison function for the profiler's hash-tables.
4769 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4770 (make_log): Use them.
4771 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4772 call Fequal any more.

4781 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4782 (hash_lookup, hash_remove_from_table): Move assertion checking of
4783 hashfn result here. Check hash-equality before calling cmpfn.

4785 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
4786 (syms_of_fns): Initialize them.

4795 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4796 value of w32-scroll-lock-modifier is neither nil nor one of the
4797 known key modifiers. (Bug#12806)
4799 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4801 Shrink struct vectorlike_header to the only size field.
4802 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4804 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4805 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4806 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4807 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4808 information from the vector header. Adjust comment.

4823 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4824 (large_vectors): Change type to struct large_vector.
4825 (allocate_vector_from_block): Simplify.
4826 (PSEUDOVECTOR_NBYTES): Replace with...
4827 (vector_nbytes): ...new function. Adjust users.
4828 (sweep_vectors): Adjust processing of large vectors.
4829 (allocate_vectorlike): Likewise.
4830 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4831 Add easserts. Adjust XSETPVECTYPESIZE usage.
4832 (allocate_buffer): Use BUFFER_PVEC_INIT.
4833 (live_vector_p): Adjust to match large vector.
4834 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4835 * buffer.h (struct buffer): Add next member.
4836 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4838 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4839 * fns.c (internal_equal): Adjust to match enum pvec_type change.

4844 (xvecsize): New command.
4846 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4848 * keyboard.c (event_to_kboard): Do not dereference
4849 frame_or_window field of SELECTION_REQUEST_EVENT
4850 and SELECTION_CLEAR_EVENT events (Bug#12814).
4851 * xterm.h (struct selection_input_event): Adjust comment.
4853 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4855 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4856 such as Scroll Lock, if the respective keys are treated as
4857 function keys, not as modifiers. This avoids destroying non-ASCII
4858 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4860 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4862 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4864 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4866 Restore some duplicate definitions (Bug#12814).
4867 This undoes part of the 2012-11-03 changes. Some people build
4868 with plain -g rather than with -g3, and they need the duplicate
4869 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4870 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4871 Define as macros, as well as as enums or as constants.
4873 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4875 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4876 to keypad keys (Bug#12816).
4878 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4880 Minor adjustments of recently-changed frame functions.
4881 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4882 known to be a frame (we're in the FRAMEP branch).
4883 * lisp.h (Qframep): Remove decl. frame.h declares this.
4884 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4885 since they're meant for Lisp fixnum values.
4887 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4889 * window.c (Fwindow_combination_limit): Revert to the only
4890 required argument and adjust docstring as suggested in
4891 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4892 by Martin Rudalics <rudalics@gmx.at>.
4894 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4896 Widely used frame validity and checking functions.
4897 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4898 * frame.c (decode_live_frame, decode_any_frame): New functions.
4899 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4900 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4901 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4902 (Fframe_pointer_visible_p): Use decode_any_frame.

4904 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4905 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4906 (Fframe_focus): Likewise. Allow zero number of arguments.
4908 (frame_buffer_list, frame_buffer_predicate): Remove.
4909 * lisp.h (frame_buffer_predicate): Remove prototype.
4910 * buffer.c (Fother_buffer): Use decode_any_frame.
4911 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4912 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4913 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4914 (Fclose_font, Ffont_info): Use decode_live_frame.
4915 * fontset.c (check_fontset_name): Likewise.
4916 * terminal.c (Fframe_terminal): Likewise.
4917 * w32fns.c (check_x_frame): Likewise.
4918 * window.c (Fminibuffer_window, Fwindow_at)
4919 (Fcurrent_window_configuration): Likewise.
4920 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4921 Likewise. Allow zero number of arguments. Adjust docstring.
4922 * dispnew.c (Fredraw_frame): Likewise.
4923 * xfaces.c (frame_or_selected_frame): Remove.
4924 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4925 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4926 (Fframe_face_alist): Use decode_live_frame.
4927 * xfns.c (check_x_frame): Likewise.
4929 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4931 * window.c (quad): New function.
4932 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4933 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4934 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4935 (Fwindow_line_height): Use it.
4936 (Fwindow_fringes): Use list3.
4937 (Fwindow_scroll_bars): Use list4.
4938 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4939 (Fwindow_combination_limit): Allow zero number of arguments.
4941 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4943 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4945 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4946 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4947 file descriptor 2 for standard error. (Bug#12805)
4949 2012-11-05 Chong Yidong <cyd@gnu.org>
4951 * process.c (wait_reading_process_output): Revert previous change.
4953 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4955 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4956 This removes code that has been obsolete since around 1990.
4957 * callproc.c (Fcall_process):
4959 * process.c (create_process):
4960 * term.c (dissociate_if_controlling_tty):
4961 Assume setsid exists.
4962 * callproc.c (child_setup): Assume setpgid exists and behaves as
4963 per POSIX.1-1988 or later.
4964 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4965 * emacs.c (shut_down_emacs):
4966 * sysdep.c (sys_suspend, init_foreground_group):
4967 Assume getpgrp behaves as per POSIX.1-1998 or later.
4968 * msdos.c (setpgrp): Remove.
4969 (tcgetpgrp, setpgid, setsid): New functions.
4970 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4971 * term.c (no_controlling_tty): Remove; unused.
4972 * w32proc.c (setpgrp): Remove.
4973 (setsid, tcgetpgrp): New functions.
4975 Simplify by assuming __fpending.
4976 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4977 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4978 Do not assume that __fpending's result fits in int.
4980 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4982 Remove EMACS_OUTQSIZE+sleep hack.
4983 * dispnew.c (update_frame_1): Remove hack for terminals slower
4984 than 2400 bps, which throttled Emacs by having it sleep.
4985 This code hasn't worked since at least 2007, when the multi-tty stuff
4986 was added, and anyway those old terminals are long dead.
4987 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4988 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4990 Fix data-loss with --version (Bug#9574).
4991 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4992 as we can't assume that emacs_strerror is initialized, and strerror
4993 is good enough here.
4994 (main): Invoke atexit earlier, to catch earlier instances of
4995 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4997 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4999 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
5000 (keyDown): Remap keypad keys to X11 virtual key codes.
5002 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5004 Fix data-loss with --batch (Bug#9574).
5005 * emacs.c: Include <close-stream.h>.
5006 (close_output_streams): New function.
5007 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5008 and handles errors appropriately.
5009 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5012 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5013 The symptom is a diagnostic "GLib-WARNING **: In call to
5014 g_spawn_sync(), exit status of a child process was requested but
5015 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5016 waitpid(), so exit status can't be returned." The diagnostic
5017 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5018 The real bug is a race condition between Emacs and glib: Emacs
5019 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5020 so that glib can't find it. Work around the bug by invoking
5021 waitpid only on subprocesses that Emacs itself creates.
5022 * process.c (create_process, record_child_status_change):
5023 Don't use special value -1 in pid field, as the caller now must
5024 know the pid rather than having the callee infer it.
5025 The inference was sometimes incorrect anyway, due to another race.
5026 (create_process): Set new 'alive' member if child is created.
5027 (process_status_retrieved): New function.
5028 (record_child_status_change): Use it.
5029 Accept negative 1st argument, which means to wait for the
5030 processes that Emacs already knows about. Move special-case code
5031 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5032 processes that have already been waited for, by testing and
5033 clearing new 'alive' member.
5034 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5035 now does this internally.
5036 (handle_child_signal): Let record_child_status_change do all
5037 the work, since we do not want to reap all exited child processes,
5038 only the child processes that Emacs itself created.
5039 * process.h (Lisp_Process): New boolean member 'alive'.
5041 Omit duplicate definitions no longer needed with gcc -g3.
5042 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5043 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5044 Define only as macros. There's no longer any need to also define
5045 these symbols as enums or as constants, since we now assume
5046 gcc -g3 when debugging.
5048 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5050 * lisp.mk: Adjust comments to the fact that term/internal is now
5051 loaded from loadup.el.
5053 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5054 (msdos_fatal_signal): New function.
5055 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5058 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5059 for GCC versions before 4.
5060 (emacs_raise): Define to call msdos_fatal_signal.
5062 * xdisp.c (init_from_display_pos): Fix initialization of the bidi

5078 * buffer.c (cursor_type): Untabify docstring.
5080 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5082 * frame.h (struct frame): Drop can_have_scroll_bars member

5128 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5130 Remove pad from struct input_event.
5131 * termhooks.h (struct input_event): Remove padding field.
5133 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5134 member is never cons for a long time. Adjust comment.
5135 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5136 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5137 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5138 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5140 2012-11-01 Eli Zaretskii <eliz@gnu.org>

5146 Fix crash when using Emacs as commit editor for git (Bug#12697).
5147 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5148 and it is configured in conf_post.h.
5149 (Fcall_process): Don't invoke both setsid and setpgid; the former
5150 is enough, if it exists.
5151 * callproc.c (Fcall_process, child_setup):
5152 * process.c (create_process): Use setpgid.
5153 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5155 * dispnew.c (init_display): Initialize the foreground group
5156 if we are running a tty display.
5157 * emacs.c (main): Do not worry about setpgrp; init_display does it now.

5169 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5171 * minibuf.c (read_minibuf): Restore current buffer since
5172 choose_minibuf_frame calling Fset_frame_selected_window may
5173 change it (Bug#12766).

5181 * font.c (Ffont_at): If WINDOW is specified and it is not
5182 displaying the current buffer, signal an error.
5184 2012-10-29 Daniel Colascione <dancol@dancol.org>
5186 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5187 In preparation for fixing bug#12739, move these functions from
5190 * coding.h, coding.c: ... to here, and compile them only when
5191 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5192 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5194 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5196 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5197 (timer_loop, getitimer, setitimer): Use it instead of

5211 remove last_appdefined_event (Bug#12698).
5213 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5215 * frame.c (x_set_font): Catch internal error.
5217 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5219 Avoid overflow in w32 implementation of interval timers.
5220 When possible, for ITIMER_PROF count only times the main thread
5222 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5223 'volatile ULONGLONG' types. All the other data which was
5224 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5225 (GetThreadTimes_Proc): New typedef.
5226 (w32_get_timer_time): New function, returns a suitable time value
5228 (timer_loop): Enter critical section when accessing ULONGLONG
5229 values of the itimer_data struct, as these accesses are no longer
5230 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5231 Remove unused variable.
5232 (init_timers): Initialize s_pfn_Get_Thread_Times.
5233 (start_timer_thread): Don't assign itimer->caller_thread here.

5240 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5241 mouse movement events if the menu bar is active. This avoids
5242 producing a busy "hour-glass" cursor by Windows if the mouse
5243 pointer is positioned over a tooltip shown for some menu item.
5245 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5247 Don't assume process IDs fit in int.
5248 * emacs.c (shut_down_emacs) [!DOS_NT]:
5249 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5250 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5251 Use pid_t, not int, to store process IDs, as 'int'
5252 is not wide enough on a few platforms (e.g., AIX and IRIX).
5254 2012-10-23 Kenichi Handa <handa@gnu.org>
5256 The following change is to make face-font-rescale-alist work
5257 correctly for non-ASCII fonts.

5277 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5279 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5281 Port to OpenBSD 5.1.
5282 * frame.c (Fmouse_position, Fmouse_pixel_position):
5283 * xdisp.c (produce_stretch_glyph):
5284 Declare local vars only when they're needed.
5285 This is clearer and avoids a warning on OpenBSD about unused vars.

5287 This is safer, and avoids OpenBSD warnings about unused vars.
5288 * keyboard.c (record_menu_key): Remove unnecessary decl.
5289 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5290 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5291 as our definition clashes with OpenBSD's.
5292 * xfaces.c (load_face_colors, check_lface_attrs)
5293 (get_lface_attributes_no_remap, get_lface_attributes)
5294 (lface_fully_specified_p, x_supports_face_attributes_p)
5295 (tty_supports_face_attributes_p, face_fontset, realize_face)
5296 (realize_x_face, realize_tty_face):
5297 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5298 merely Lisp_Object *. This is more informative and avoids
5299 a warning on OpenBSD about accessing beyond an object's size.
5301 2012-10-20 Chong Yidong <cyd@gnu.org>
5303 * lread.c (Fload): Doc fix (Bug#12592).

5329 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5330 (staticpro): If we run out of staticpro slots, die with an
5331 informative error instead of just calling emacs_abort.
5333 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5335 Fix two flaws reported by Dmitry Antipov.

5586 * keyboard.c (timers_run, swallow_events)
5587 (detect_input_pending_run_timers):
5588 * process.c (wait_reading_process_output):
5589 Use unsigned for counter where wraparound-on-overflow is desired,
5590 since unsigned is guaranteed to have that behavior and signed is not.
5591 (read_char): Use ptrdiff_t for string length.
5592 (get_input_pending): Remove first argument, since it was always
5593 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5594 and behave as if it had that value. Return new value of
5595 input_pending. All callers changed.
5596 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5597 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5599 * keymap.c (push_key_description): Omit last arg, which was always 1.
5600 All callers changed.
5602 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

5613 initializer for PVEC_NORMAL_VECTOR.
5615 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5617 Clean out old termopts cruft.
5618 * termopts.h (flow_control, meta_key): Remove unused decls.
5619 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5620 Don't include termopts.h.
5622 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5624 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5626 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5628 * commands.h (immediate_quit): Remove duplicate decl.
5630 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5632 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5635 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5637 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5639 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5640 match what GetLastError returns. Explain why the function is
5643 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5644 'is_tooltip_frame', to avoid confusion with its global namesake.
5646 2012-10-08 Daniel Colascione <dancol@dancol.org>
5648 * xdisp.c (start_hourglass): Call w32_note_current_window when
5649 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5650 build that caused Emacs to display the hourglass cursor forever.
5652 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5653 which is broken under remote desktop, calculate the number of
5654 colors available for a display based on the display's number of
5655 planes and number of bits per pixel per plane. (bug#10397).
5657 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5659 * nsfont.m (Vfonts_in_cache): New variable.
5660 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5661 are used. Add cached fonts to Vfonts_in_cache.
5662 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5664 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5666 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5668 (FONT_H): Define after FRAME_H.
5669 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5670 Update dependencies.
5672 * w32term.c: Remove leftover declaration of keyboard_codepage.
5674 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5676 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5677 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5678 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5679 (GLOBAL_SOURCES): Add cygw32.c.
5680 ($(BLD)/unexw32.$(O)):
5682 ($(BLD)/w32console.$(O)):
5683 ($(BLD)/w32fns.$(O)):
5684 ($(BLD)/w32heap.$(O)):
5685 ($(BLD)/w32menu.$(O)):
5686 ($(BLD)/w32proc.$(O)): Add w32common.h.
5688 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5690 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5692 2012-10-08 Daniel Colascione <dancol@dancol.org>
5694 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5695 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5696 accidental message numbering hole. Change other messages to
5699 * w32select.h (HAVE_W32SELECT): Remove.
5701 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5702 w32common.h instead of w32heap.h.
5704 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5705 (get_allocation_unit, get_processor_type, get_w32_major_version)
5706 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5707 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5708 (OS_NT, os_subtype, cache_system_info): Move declarations to
5711 * w32heap.c: Include w32common.h.
5712 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5713 (w32_minor_version, w32_build_number, w32_subtype):
5714 Remove duplicate definitions.
5716 * w32fns.c: Include w32common.h; include w32heap.h only in
5719 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5720 Use `report_file_error' instead of `error' in order to better
5721 inform users of what went wrong. Increase NTGUI_UNICODE file
5722 dialog box file name length to 32k, the maximum allowed by the NT
5725 * w32common.h: New file.
5726 (ROUND_UP, ROUND_DOWN, get_page_size)
5727 (get_allocation_unit, get_processor_type, get_w32_major_version)
5728 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5729 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5730 (OS_NT, os_subtype, cache_system_info): Move here.
5732 * unexw32.c, unexcw.c: Include w32common.h.
5734 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5735 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5736 to call syms_of_w32select.
5738 * cygw32.h: Remove obsolete EXFUN declarations.
5740 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5742 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5743 of w32inevt.o from SOME_MACHINE_OBJECTS.
5745 2012-10-08 Daniel Colascione <dancol@dancol.org>
5747 * image.c: Permanent fix for JPEG compilation issue --- limit
5748 jpeglib `boolean' redefinition to Cygwin builds.
5750 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5752 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5754 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5757 2012-10-08 Daniel Colascione <dancol@dancol.org>
5759 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5760 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5761 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5762 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5763 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5764 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5765 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5766 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5767 now a supported configuration.
5769 * Makefile.in: consolidate image variables into LIBIMAGE; add
5770 W32_OBJ and W32_LIBS. Compile new files.
5773 (_DebPrint) declare tracing facility for W32 debugging. We need
5774 to unify tracing later.
5776 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5777 unconditional use of W32 Unicode functions. Cygwin runs only on
5778 100% Unicode operating systems.
5780 * cygw32.c: New file. Define Cygwin-specific facilities.
5781 (Fcygwin_convert_path_to_windows)
5782 (Fcygwin_convert_path_from_windows): New user functions for
5783 accessing Cygwin path-munging routines.
5785 * cygw32.h: New file.
5786 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5787 UTF-16LE strings temporarily inside non-Lisp-visible string
5790 (w32_strerror): Just what it says on the tin.
5792 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5793 also run for Cygwin; both systems have the same problem with using
5794 GUI facilities in a forked child. Also call syms_of_cygw32,
5795 syms_of_w32select in correct places.
5797 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5798 needs fork-then-exec for daemon launching.
5800 * font.h: Include frame.h.
5802 * image.c: Use the image library cache machinery only when we're
5803 compiling for native WINDOWSNT; Cygwin can use shared libraries
5804 like any other Unixlike system.
5806 * keyboard.c: Clarify a comment regarding the input loop.
5808 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5809 functions directly instead of trying to detect at runtime that our
5810 host operating system supports them. We make this change for two
5811 reasons: Cygwin lacks support for the multibyte character
5812 conversion functions used by the legacy menu code, and Cygwin
5813 never needs to rely on non-Unicode APIs.
5815 * unexw32.c (hinst): Declare extern.
5817 * w32.c: Change header order;
5818 (w32_strerror): Move to w32fns.c because we need it for
5819 non-WINDOWSNT builds.
5821 * w32.h: Add #error macro to make sure we don't include w32.h for
5822 Cygwin builds. Remove w32select declarations.
5824 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5825 w32fns.c. w32console.c is WINDOWSNT-only.
5827 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5828 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5830 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5831 (w32_major_version, w32_minor_version, w32_build_number)
5832 (os_subtype, sound_type): Define here
5833 (w32_defined_color): Make color parameter const for consistency
5834 with other _defined_color functions.
5835 (w32_createwindow): Unconditionally call w32_init_class instead of
5836 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5837 through the code is complex and unnecessary because class
5838 registration is practically free.
5839 (w32_name_of_message): New EMACSDEBUG-only function.
5840 (Fset_message_beep): Move here
5841 (Fx_open_connection): Require that the display name for Windows be
5842 "w32" for consistency, emacsclient disambiguation, and maybe, one
5843 day, multi-window-system support.
5844 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5845 Cygwin files for W32 GUI facilities, since these clearly don't
5846 expect Cygwin names.
5847 (_DebPrint): Define.
5848 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5849 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5850 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5851 (w32_last_error): Remove.
5853 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5855 * w32heap.c (syspage_mask): Declare here.
5856 (cache_system_info): Remove.
5858 * w32inevt.c (faked_key): Define globally, not statically.
5859 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5860 (w32_console_toggle_lock_key): Move to w32fns.c.
5862 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5864 * w32proc.c (_DebPrint): Move to w32fns.c.
5865 * w32select.c: Include string.h, stdio.h for Cygwin.
5866 * w32select.h: New File.
5868 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5870 (w32_message_fd): New variable. Under Cygwin, holds the file
5871 descriptor the system used to tell us about pending thread
5874 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5875 that prevented compilation under non-WINDOWSNT systems.
5877 (w32_initialize): Open /dev/windows and assign it to
5878 w32_message_fd. Provide w32 feature.
5880 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5881 (WM_EMACS_INPUT_READY): add.
5882 (prepend_msg, w32_message_fd): Declare globally.
5885 (keyboard_handle): Use only when WINDOWSNT.
5886 (notify_msg_ready): New function. Posts a message to the main
5887 thread's message queue under CYGWIN, which wakes up the main
5888 thread from select(2) by making the /dev/windows file descriptor
5889 ready. Under WINDOWSNT, it sets an event the same way the old
5892 (post, prepend_msg): Actually call notify_msg_ready instead of
5893 setting the input event directly.
5895 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5897 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5898 but it still has blocs in it, don't return it to the system,
5899 instead of aborting. (Bug#12402)
5901 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5903 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5905 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5906 MAC_OS_X_VERSION_10_6.
5907 (syms_of_nsterm): Remove comment about Panther and above for
5909 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5910 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5911 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5913 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5914 MAC_OS_X_VERSION_10_4.
5916 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5917 MAC_OS_X_VERSION_10_2.
5919 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5921 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5922 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5924 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5925 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5926 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5927 Remove ns_in_resize check.
5928 (ns_clear_frame_area): Remove resize handle code.
5930 * nsfns.m (ns_in_resize): Remove.
5931 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5932 Remove ns_in_resize check.
5934 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5936 Improve sys_siglist detection.
5937 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5938 defined as a macro, as is done in Solaris.
5939 (sys_siglist_entries): New macro.
5940 (save_strsignal): Use it.
5941 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5942 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5944 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5946 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5947 fullscreen/Fullscreen.
5949 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5950 tobar_height is new.
5952 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5953 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5954 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5955 (windowDidResize:): Check for correct window if old style fullscreen.
5956 Capitalize word in comment. Remove incorrect comment.
5957 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5958 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5959 error in drawing background.
5960 (toggleFullScreen:): Remove comment. Rearrange calls.
5961 Set toolbar values to zero, save old height in tobar_height.
5962 Restore tool bar height when leaving fullscreen.
5963 (canBecomeMainWindow): New function.
5965 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5967 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5969 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5971 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5973 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5974 that time stamps of directories could also be changed.
5975 Don't request the too broad GENERIC_WRITE, only the more restrictive
5976 FILE_WRITE_ATTRIBUTES access rights.
5978 * fileio.c (Fset_file_times): Special-case ignoring errors for
5979 directories only on MSDOS, not on MS-Windows.
5981 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5983 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5985 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5987 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5988 see whether CreateFile failed.
5990 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5992 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5993 to avoid similar races.
5994 * keyboard.c (pending_signals): Now bool, not int.
5996 Port timers to OpenBSD, plus check for timer failures.
5997 OpenBSD problem reported by Han Boetes.
5998 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6000 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6001 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6002 like OpenBSD, which has timer_settime but does not declare it.
6003 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6004 whether to use itimerspec-related primitives. All uses of
6005 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6007 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6009 * profiler.c (handle_profiler_signal): Fix a malloc race
6010 that caused Emacs to hang on Fedora 17 when profiling Lisp.

6033 Now 'static', not 'static inline'.
6035 Count overruns when profiling; change units to ns.
6036 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6037 Give extra weight to samples after overruns, to attempt to count
6038 the time more accurately.
6039 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6040 the underlying primitives nominally do ns.
6041 (Fprofiler_cpu_start): Document the change. Mention that
6042 the sampling intervals are only approximate.

6058 Update dependencies.
6060 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6062 Fix a malloc race condition involving strsignal.
6063 A signal can arrive in the middle of a malloc, and Emacs's signal
6064 handler can invoke strsignal, which can invoke malloc, which is
6065 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6066 Fix it by altering the signal handler so that it does not invoke
6068 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6069 * process.c (status_message): Use const pointer, in case strsignal
6070 is #defined to safe_strsignal.
6071 * sysdep.c (sys_siglist, init_signals): Always define and
6072 initialize a substitute sys_siglist if the system does not define
6073 one, even if HAVE_STRSIGNAL.
6074 (safe_strsignal): Rename from strsignal. Always define,
6075 using sys_siglist. Return a const pointer.
6076 * syssignal.h (safe_strsignal): New decl.
6077 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6079 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6081 * w32proc.c (timer_loop): Fix code that waits for timer
6082 expiration, to avoid high CPU usage.
6084 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6086 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6087 (sweep_weak_table): Remove redundant prototypes.
6089 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6091 * emacs.c: Move the inclusion of TERM_HEADER after including
6092 windows.h on WINDOWSNT. This avoids compilation problems with
6095 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6097 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6098 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6099 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6100 as the previous version used 'void *'.
6102 * ralloc.c (ROUNDUP): Fix last change.
6103 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6106 * w32proc.c <disable_itimers>: New static flag.
6107 (init_timers): Initialize it to zero, after creating the critical
6108 sections used by the timer threads.
6109 (term_timers): Set to 1 before deleting the critical sections.
6110 (getitimer, setitimer): If disable_itimers is non-zero, return an
6111 error indication without doing anything. Reported by Fabrice
6112 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6113 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6115 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6118 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6119 term_ntproc after all the other bookkeeping, to get timers working
6120 as long as possible.
6122 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6124 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6125 Suggested by Juri Linkov in
6126 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6128 Prefer plain 'static' to 'static inline' (Bug#12541).
6129 With static functions, modern compilers inline pretty well by
6130 themselves; advice from programmers often hurts as much as it helps.
6131 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6132 this change shrinks the text size of the Emacs executable by 1.1%
6133 without affecting CPU significantly in my benchmark.

6256 * w32.c (init_environment, get_emacs_configuration): Support AMD64
6258 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
6259 compatibility with x64.
6261 * vm-limit.c (lim_data): Now size_t.
6262 (check_memory_limits): Adjust prototypes of real_morecore and
6263 __morecore to receive argument of type ptrdiff_t. Use size_t for

6290 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows
6293 * image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since

6317 sigfillset, and sigprocmask are no longer no-ops.
6318 (sigismember): New function.
6319 (struct itimer_data): New definition.
6320 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

6349 2012-09-30 Kenichi Handa <handa@gnu.org>
6351 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
6352 to the buffer relocation which may be caused by ccl_driver.

6409 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6411 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6412 HAVE_TIMER_SETTIME is defined.
6414 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6416 Profiler improvements: more-accurate timers, overflow checks.
6417 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6418 signal.h, setjmp.h. Include systime.h instead.
6419 (saturated_add): New function.
6420 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6421 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.

6426 All uses changed to store the new value.
6427 (handle_profiler_signal): Rename from sigprof_handler_1,
6428 for consistency with other handlers. Do not check whether
6429 cpu_log is a hash-table if garbage collecting, since it
6430 doesn't matter in that case.
6431 (deliver_profiler_signal): Rename from sigprof_handler,
6432 for consistency with other handlers.
6433 (setup_cpu_timer): New function, with much of what used to be in
6434 Fprofiler_cpu_start. Check for out-of-range argument.
6435 Prefer timer_settime if available, and prefer
6436 thread cputime clocks, then process cputime clocks, then
6437 monotonic clocks, to the old realtime clock. Use make_timeval
6438 to round more-correctly when falling back to setitimer.
6439 (Fprofiler_cpu_start): Use it.
6440 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6441 Don't assume that passing NULL as the 2nd argument of setitimer
6442 is the same as passing a pointer to all-zero storage.
6443 Ignore SIGPROF afterwards.
6444 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6445 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6446 non-fatal signal handlers. Ignore SIGPROF on startup.
6447 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6448 in profiler.c, since sysdep.c now uses it.
6450 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

6463 * alloc.c (Fgarbage_collect):
6464 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
6465 (Fbacktrace_frame): Adjust accordingly.
6467 2012-09-28 Glenn Morris <rgm@gnu.org>
6469 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
6470 (Frun_hook_with_args_until_failure): Doc fixes.
6472 2012-09-28 Eli Zaretskii <eliz@gnu.org>
6474 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

6505 * charset.c, charset.h (maybe_unify_char): Now static.
6506 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6507 Since this stuff is now private to charset.c, there's no need for
6508 a public macro and no need to inline by hand.
6510 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
6511 Stefan Monnier <monnier@iro.umontreal.ca>
6512 Juanma Barranquero <lekktu@gmail.com>

6537 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6539 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6541 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6543 Prefer POSIX timers if available.
6544 They avoid a race if the timer is too close to the current time.
6545 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6546 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

6554 STRING_CHAR_ADVANCE.
6556 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6558 Move Vlibrary_cache to emacs.c and reset before dumping.
6560 * lisp.h (reset_image_types): Declare.
6561 [WINDOWSNT] (Vlibrary_cache): Declare.
6563 * image.c (reset_image_types): New function.
6565 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
6566 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
6567 (Fdump_emacs): Reset Vlibrary_cache and image_types.

6572 * w32.h (Vlibrary_cache): Do not declare.
6574 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6576 * w32proc.c (sys_signal): Handle all signals defined by the
6577 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6578 handlers for signals supported by Windows. Don't override
6579 term_ntproc as the handler for SIGABRT.
6580 (sigaction): Rewrite to call sys_signal instead of duplicating its
6582 (sys_kill): Improve commentary.
6584 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6585 consistency with a signature of a signal handler. All callers
6587 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6588 install term_ntproc as a signal handler for SIGABRT, as that
6589 should be done by the dumped Emacs.
6591 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6593 * w32select.c (term_w32select): Protect against repeated
6594 invocation by setting clipboard_owner to NULL after calling
6597 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6598 and term_ntproc to their modified signatures.
6600 * character.c (char_string, string_char): Remove calls to
6601 MAYBE_UNIFY_CHAR. See the discussion starting at
6602 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6605 2012-09-25 Chong Yidong <cyd@gnu.org>
6607 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6609 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6611 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6612 when encountering an unknown bytecode.
6614 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6616 image.c, indent.c: Use bool for booleans.
6617 * dispextern.h (struct image_type): Members valid_p, load, init
6618 now return bool, not int. All uses changed.
6619 * image.c: Omit unnecessary static decls.
6620 (x_create_bitmap_mask, x_build_heuristic_mask):
6621 Return void, not int, since callers don't care about the return value.

6650 Use bool for booleans.
6652 2012-09-24 Chong Yidong <cyd@gnu.org>
6654 * chartab.c (Fset_char_table_default): Obsolete function removed.
6656 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6658 Move pid_t related decls out of lisp.h.
6659 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6660 (interruptible_wait_for_termination):
6661 Move these decls from lisp.h to syswait.h, since they use pid_t.
6662 Needed on FreeBSD; see Herbert J. Skuhra in
6663 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6664 * callproc.c: Include syswait.h.

6681 * nsmenu.m (ns_update_menubar):
6682 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6683 * xfns.c (Fx_show_tip) [USE_GTK]:
6684 Use bool for boolean.
6685 * gtkutil.c (xg_update_frame_menubar):
6686 * xmenu.c (update_frame_menubar):
6687 Return void, not int, since caller ignores return value.

6691 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6693 * makefile.w32-in (BLOCKINPUT_H): Remove.

6710 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6712 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6713 fatal_error_backtrace.
6715 * w32proc.c (sys_kill): Undo last change: don't do anything when
6716 invoked to deliver SIGABRT to our own process. This is now
6717 handled by emacs_raise.
6719 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6721 * w32term.c (w32_read_socket): Remove leftover reference to
6722 interrupt_input_pending.
6724 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6726 Do not use SA_NODEFER.
6727 Problem reported by Dani Moncayo in
6728 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6730 * sysdep.c (emacs_abort): Do not reset signal handler.
6731 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6732 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6733 wanted even on POSIXish hosts, and it doesn't work on Windows.
6735 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6737 * xterm.c (x_term_init): Call fixup_locale before and after calling
6738 gtk_init (Bug#12392).
6740 2012-09-23 Chong Yidong <cyd@gnu.org>
6742 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6743 Vdynamic_library_alist.
6745 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6746 (Fgnutls_available_p): Caller changed.
6748 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6749 (Flibxml_parse_xml_region): Likewise.
6751 * dispextern.h (struct image_type): Remove arg from init function.
6753 * image.c (Finit_image_library, lookup_image_type)
6754 (define_image_type): Remove now-unneeded second arg.
6755 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6756 (init_tiff_functions, init_gif_functions, init_svg_functions):
6757 Arglist and w32_delayed_load calling convention changed.
6758 (gs_type): Remove init_gs_functions; there is no such function.
6759 (valid_image_p, make_image): Fix caller to lookup_image_type.
6761 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6763 Simplify and avoid signal-handling races (Bug#12471).
6765 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6766 Avoid recursive loop if there's a fatal error in the function itself.
6767 * atimer.c (pending_atimers):
6768 * blockinput.h: Don't include "atimer.h"; no longer needed.
6769 (interrupt_input_pending): Remove. All uses removed.
6770 pending_signals now counts both atimers and ordinary interrupts.
6771 This is less racy than having three separate pending-signal flags.
6772 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6774 Rename from their upper-case counterparts BLOCK_INPUT,
6775 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6776 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6777 This makes it easier to access volatile variables more accurately.
6778 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6779 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6780 that's more reliable if the code is buggy and sets
6781 interrupt_input_blocked to a negative value. All uses changed.
6782 * atimer.c (deliver_alarm_signal):
6783 Remove. No need to deliver this to the parent; any thread can
6784 handle this signal now. All uses replaced by underlying handler.
6785 * atimer.c (turn_on_atimers):
6786 * dispnew.c (handle_window_change_signal):
6787 * emacs.c (handle_danger_signal):
6788 * keyboard.c (kbd_buffer_get_event):
6789 Don't reestablish signal handler; not needed with sigaction.
6790 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6792 Rework to avoid unnecessary accesses to volatile variables.
6793 (UNBLOCK_INPUT_TO): Now a function.
6794 (totally_unblock_input, unblock_input): New decls.
6795 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6796 (init_data): Remove. Necessary stuff now done in init_signal.
6797 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6798 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6799 (fatal_error_code): Remove; no longer needed.
6800 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6801 it doesn't always backtrace. All uses changed. No need to reset
6802 signal to default, since sigaction and/or die does that for us now.
6803 Use emacs_raise (FOO), not kill (getpid (), FOO).
6804 (main): Check more-accurately whether we're dumping.
6805 Move fatal-error setup to sysdep.c
6806 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6807 * gtkutil.c (xg_get_file_name, xg_get_font):
6808 Remove no-longer-needed signal-mask manipulation.
6809 * keyboard.c, process.c (POLL_FOR_INPUT):
6810 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6811 * keyboard.c (read_avail_input): Remove.
6812 All uses replaced by gobble_input.
6813 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6814 (kbd_buffer_store_event_hold, gobble_input):
6815 (record_asynch_buffer_change) [USABLE_SIGIO]:
6816 (store_user_signal_events):
6817 No need to mess with signal mask.
6818 (gobble_input): If blocking input and there are terminals, simply
6819 set pending_signals to 1 and return. All hooks changed to not
6820 worry about whether input is blocked.
6821 (process_pending_signals): Clear pending_signals before processing
6822 them, in case a signal comes in while we're processing.
6823 By convention callers now test pending_signals before calling us.
6824 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6825 New functions, to support changes to blockinput.h.
6826 (handle_input_available_signal): Now extern.
6827 (reinvoke_input_signal): Remove. All uses replaced by
6829 (quit_count): Now volatile, since a signal handler uses it.
6830 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6831 All callers changed. Block SIGINT only if not already blocked.
6832 Clear sigmask reliably, even if Fsignal returns, which it can.
6833 Omit unnecessary accesses to volatile var.
6834 (quit_throw_to_read_char): No need to restore sigmask.
6835 * keyboard.c (gobble_input, handle_user_signal):
6836 * process.c (wait_reading_process_output):
6837 Call signal-handling code rather than killing ourselves.
6838 * lisp.h: Include <float.h>, for...
6839 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6840 (pending_signals): Now volatile.
6841 (syms_of_data): Now const if IEEE floating point.
6842 (handle_input_available_signal) [USABLE_SIGIO]:
6843 (terminate_due_to_signal, record_child_status_change): New decls.
6844 * process.c (create_process): Avoid disaster if memory is exhausted
6845 while we're processing a vfork, by tightening the critical section
6847 (send_process_frame, process_sent_to, handle_pipe_signal)
6848 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6850 (send_process): No need for setjmp/longjmp any more, since the
6851 SIGPIPE stuff is now gone. Instead, report an error if errno
6853 (record_child_status_change): Now extern. PID and W are now args.
6854 Return void, not bool. All callers changed.
6855 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6856 Remove. All uses removed. This bug should be fixed now in a
6858 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6859 and record the child status change directly. This avoids the
6860 need to futz with the signal mask.
6861 (process_fatal_action): Move here from emacs.c.
6862 (emacs_sigaction_flags): New function, containing
6863 much of what used to be in emacs_sigaction_init.
6864 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6865 caught by emacs, to make races less likely.
6866 (deliver_process_signal): Rename from handle_on_main_thread.
6868 (BACKTRACE_LIMIT_MAX): Now at top level.
6869 (thread_backtrace_buffer, threadback_backtrace_pointers):
6871 (deliver_thread_signal, deliver_fatal_thread_signal):
6872 New functions, for more-accurate delivery of thread-specific signals.
6873 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6874 (deliver_arith_signal): Handle in this thread, not
6875 in the main thread, since it's triggered by this thread.
6876 (maybe_fatal_sig): New function.
6877 (init_signals): New arg DUMPING so that we can be more accurate
6878 about whether we're dumping. Caller changed.
6879 Treat thread-specific signals differently from process-general signals.
6880 Block all signals while handling fatal error; that's safer.
6881 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6883 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6884 Ignore SIGPIPE unless batch.
6885 (emacs_backtrace): Output backtrace for the appropriate thread,
6886 which is not necessarily the main thread.
6887 * syssignal.h: Include <stdbool.h>.
6888 (emacs_raise): New macro.
6889 * xterm.c (x_connection_signal): Remove; no longer needed
6890 now that we use sigaction.
6891 (x_connection_closed): No need to mess with sigmask now.
6892 (x_initialize): No need to reset SIGPIPE handler here, since
6893 init_signals does this for us now.
6895 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6897 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6898 background rect may be larger (Bug#12245).
6900 2012-09-23 Chong Yidong <cyd@gnu.org>
6902 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6904 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6906 * .gdbinit: Just stop at fatal_error_backtrace.
6907 See Stefan Monnier's request in
6908 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6909 Remove no-longer-used query of system type.
6911 2012-09-22 Chong Yidong <cyd@gnu.org>
6913 * search.c (Freplace_match): Doc fix (Bug#12325).
6915 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6917 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6918 (Fline_end_position): Doc fix.
6920 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6922 2012-09-22 Chong Yidong <cyd@gnu.org>
6924 * dispextern.h (struct image_type): Add new slot, storing a type
6925 initialization function.
6927 * image.c (define_image_type): Call the image initializer function
6928 if it is defined. Arguments and return value changed.
6929 (valid_image_p, make_image): Callers changed.
6930 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6931 (gif_type, imagemagick_type, svg_type, gs_type):
6932 Add initialization functions.
6933 (Finit_image_library): Call lookup_image_type.
6934 (CHECK_LIB_AVAILABLE): Macro deleted.
6935 (lookup_image_type): Call define_image_type here, rather than via
6936 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6937 (syms_of_image): Move define_image_type calls for xbm_type and
6938 pbm_type to lookup_image_type.
6940 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6942 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6943 'idle_timers' from here ...
6944 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6945 lists, to avoid infloops when the timer does something stupid,
6946 like reinvoke itself with the same or smaller time-out.
6949 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6951 * window.c (Fsplit_window_internal): Handle only Qt value of
6952 Vwindow_combination_limit separately.
6953 (Qtemp_buffer_resize): New symbol.
6954 (Vwindow_combination_limit): New default value.
6957 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6959 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6960 the new overlay string. (Bug#10159)
6962 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6964 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6965 or that fprintf is async-signal-safe. POSIX doesn't require
6968 2012-09-22 Chong Yidong <cyd@gnu.org>
6970 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6973 2012-09-22 Kenichi Handa <handa@gnu.org>
6975 * composite.c (composition_reseat_it): Handle the case that a
6976 grapheme cluster is not covered by a single font (Bug#12352).
6978 2012-09-21 Chong Yidong <cyd@gnu.org>
6980 * image.c (define_image_type): Avoid adding duplicate types to
6981 image_types (Bug#12463). Suggested by Jörg Walter.
6983 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6985 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6986 (print_load_command_name): Add case LC_DATA_IN_CODE.
6987 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6989 2012-09-21 Glenn Morris <rgm@gnu.org>
6991 * eval.c (Frun_hook_with_args_until_success)
6992 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6994 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6996 * fileio.c (Ffile_selinux_context): Only call freecon when
6997 lgetfilecon succeeded.
6998 (Fset_file_selinux_context): Likewise. (Bug#12444)
7000 2012-09-21 Eli Zaretskii <eliz@gnu.org>
7002 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7003 reordering, locate the cursor by calling set_cursor_from_row; if
7004 that fails, clear the desired glyph matrix before returning a
7005 failure indication to the caller. Fixes leaving garbled display
7006 when fast scrolling with a down-key. (Bug#12403)
7007 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7008 scrolling through multibyte text.
7010 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7012 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7013 calling mark_vectorlike since that's the one that marks the window.
7014 (mark_discard_killed_buffers): Mark the final cdr.
7015 * window.h (struct window): Move prev/next_buffers to the
7016 non-standard fields.
7017 * window.c (make_window): Initialize prev/next_buffers manually.
7019 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7021 Omit unused arg EXPECTED from socket hooks.
7022 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7023 * nsterm.m (ns_term_init):
7024 * termhooks.h (struct terminal.read_socket_hook):
7025 * w32inevt.c (w32_console_read_socket):
7026 * w32term.c (w32_read_socket):
7027 * xterm.c (XTread_socket):
7028 Omit unused arg EXPECTED. All callers changed.
7029 (store_user_signal_events): Return void, not int, since callers no
7030 longer care about the return value. All uses changed.
7032 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7034 * w32gui.h (XParseGeometry): Do not declare.
7036 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7038 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7039 Ignore 'expected'. See Eli Zaretskii in
7040 <http://bugs.gnu.org/12471#8> (last line).
7042 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7043 (XParseGeometry): Now static. Substitute extremal values for
7044 values that are out of range.
7046 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7048 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7050 * nsfns.m (XParseGeometry): Remove.
7051 (Fx_create_frame): Call x_set_offset to correctly interpret
7052 top_pos in geometry.
7054 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7055 (Fx_parse_geometry): If there is a space in string, call
7056 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7058 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7060 * search.c (scan_buffer): Use character positions in calls to
7061 region_cache_forward and region_cache_backward, not byte
7062 positions. (Bug#12196)
7064 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7065 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7067 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7068 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7069 emacs_blocked_malloc, now deleted.
7071 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7073 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7074 The workaround was for improving performance on Solaris 2.4, but
7075 is getting in the way now. Emacs will still work if someone is
7076 still running Solaris 2.4 in a museum somewhere; Sun dropped
7077 support for Solaris 2.4 in 2003.
7078 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7079 * process.c (create_process) [HAVE_WORKING_VFORK]:
7080 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7081 since Emacs no longer uses vfork on that platform.
7083 2012-09-17 Glenn Morris <rgm@gnu.org>
7085 * emacs.c: Use COPYRIGHT.
7087 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7089 Remove configure's --without-sync-input option (Bug#12450).
7090 When auditing signal-handling in preparation for cleaning it up,
7091 I found that SYNC_INPUT has race conditions and would be a real
7092 pain to fix. Since it's an undocumented and deprecated
7093 configure-time option, now seems like a good time to remove it.
7094 Also see <http://bugs.gnu.org/11080#16>.
7095 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7096 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7097 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7098 (malloc_hysteresis):
7099 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7100 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7101 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7102 (dont_register_blocks, bytes_used_when_reconsidered)
7103 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7104 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7105 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7106 Remove. All uses removed.
7107 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7108 implementation, one that depends on whether the new macro
7109 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7111 * atimer.c (run_timers, handle_alarm_signal):
7112 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7113 (handle_async_input, process_pending_signals)
7114 (handle_input_available_signal, init_keyboard):
7115 * nsterm.m (ns_read_socket):
7116 * process.c (wait_reading_process_output):
7117 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7118 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7120 * xterm.c (XTread_socket):
7122 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7123 * eval.c (handling_signal): Remove. All uses removed.
7124 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7125 All uses replaced with the SYNC_INPUT version.
7126 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7128 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7131 * font.c (Ffont_shape_gstring): Remove unused local.
7133 2012-09-16 Glenn Morris <rgm@gnu.org>
7135 * Makefile.in (clean): No longer run nextstep's clean.
7137 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7139 (ns-app): Move here from ns.mk, and simplify.
7140 (clean): Simplify nextstep entry.
7141 * ns.mk: Remove file.
7143 2012-09-17 Kenichi Handa <handa@gnu.org>
7145 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7146 not covert the last few charactes.
7148 2012-09-16 Kenichi Handa <handa@gnu.org>
7150 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7151 here, but just check the validity of glyphs in the glyph-string.
7153 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7155 * window.c (Fwindow_parameter, Fset_window_parameter):
7156 Accept any window as argument (Bug#12452).
7158 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7160 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7161 to ns_term_init to avoid memory leak.
7163 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7164 explicit retain/release.
7165 (ns_term_init): Only allow one display. Initialize outerpool and
7168 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7170 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7171 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7172 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7173 the Microsoft problem in a different way, by altering ../nt/config.nt.
7175 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7190 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7191 by lisp.h. This completes removal of setjmp.h inclusion
7192 erroneously announced in the previous commit. (Bug#12446)
7194 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7197 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7198 not defined as a macro. The latter happens on MS-Windows.
7201 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7203 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7204 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7205 Some instances of '#include <setjmp.h>' removed, if the
7206 only reason for the instance was because "lisp.h" was included.
7207 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7208 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7209 and _longjmp with the new symbols. Emacs already uses _setjmp if
7210 available, so this change affects only POSIXish hosts that have
7211 sigsetjmp but not _setjmp, such as some versions of Solaris and
7212 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7213 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7214 (png_load_body) [HAVE_PNG]:
7215 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7216 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7217 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7218 since PNG requires jmp_buf. This is the only exception to the
7219 general rule that we now use sys_setjmp and sys_longjmp.
7220 This exception is OK since this code does not change the signal
7221 mask or longjmp out of a signal handler.
7223 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7225 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7226 Include "syssignal.h", for 'main_thread'.
7228 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7230 Avoid out-of-range marker position (Bug#12426).
7231 * insdel.c (replace_range, replace_range_2):
7232 Adjust markers before overlays, as suggested by comments.
7233 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7234 Remove redundant check before calling offset_intervals.
7236 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7238 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7239 current buffer (Bug#12387).
7241 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7243 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7245 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7247 Use a more backwards-compatible timer format (Bug#12430).
7248 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7249 vector element, not from the 4th, since PSECS is now at the end.
7250 (Fcurrent_idle_time): Doc fix.
7252 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7254 Function to mark objects and remove killed buffers at once.
7255 * alloc.c (discard_killed_buffers): Rename to ...
7256 (mark_discard_killed buffers) ... new name. Add marking
7257 of remaining objects. Fix comment. Adjust users.
7258 (mark_object): Do not touch frame buffer lists here.
7259 * frame.c (delete_frame): Reset frame buffer lists here.
7261 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7263 Better workaround for GNOME bug when --enable-gcc-warnings.
7264 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7265 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7266 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7268 Simplify SIGIO usage (Bug#12408).
7269 The code that dealt with SIGIO was crufty and confusing, e.g., it
7270 played tricks like "#undef SIGIO" but these tricks were not used
7271 consistently. Simplify mostly by not #undeffing standard symbols,
7272 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7273 or not as we please) rather than "defined SIGIO" (standard symbol
7274 that we probably shouldn't #undef).
7275 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7276 Modules that need it can include it.
7277 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7278 * dispextern.h (ignore_sigio): New decl.
7279 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7280 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7281 * emacs.c (shut_down_emacs):
7282 * keyboard.c (kbd_buffer_store_event_hold):
7283 Use ignore_sigio rather than invoking 'signal' directly.
7284 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7286 (FIONREAD, SIGIO): Do not #undef.
7287 (tty_read_avail_input): Use #error rather than a syntax error.
7288 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7289 for I_PIPE, used by SETUP_SLAVE_PTY.
7290 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7291 * sysdep.c (croak): Remove; no longer needed. This bit of
7292 temporary code, with Fred N. Fish's comment that it's temporary,
7293 has been in Emacs since at least 1992!
7294 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7295 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7296 * syssignal.h (croak): Remove decl.
7297 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7298 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7299 now that we're termios-only.
7300 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7301 * term.c (dissociate_if_controlling_tty): Use #error rather than
7304 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7305 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7306 to work around GNOME bug 683906.
7307 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7308 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7309 This works around GCC bug 54561.
7311 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7313 More fixes for 'volatile' and setjmp/longjmp.
7314 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7315 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7316 (png_load_body) [HAVE_PNG]:
7317 (jpeg_load_body) [HAVE_JPEG]:
7318 New function, with most of the old parent function's body.
7319 (png_load) [HAVE_PNG]:
7320 (jpeg_load) [HAVE_JPEG]:
7321 Invoke the new function, to avoid longjmp munging our locals.
7322 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7323 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7324 longjmp is passed 2, as the C standard doesn't guarantee this.
7325 Instead, store the failure code into mgr->failure_code.
7327 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7329 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7330 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7331 (syms_of_keyboard): Remove support for unread-command-char.
7333 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7335 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7336 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7337 violation. (Bug#12426)
7339 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7341 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7343 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7345 * eval.c: Add `inhibit-debugger'.
7346 (Qinhibit_debugger): New symbol.
7347 (call_debugger): Bind it instead of Qdebug_on_error.
7348 (maybe_call_debugger): Test Vinhibit_debugger.
7349 (syms_of_eval): Define inhibit-debugger.
7350 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7351 (syms_of_xdisp): Remove inhibit-debug-on-message.
7353 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7355 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7356 If a nonvolatile local variable is written before a _longjmp to
7357 the frame containing the variable, and is read after the _longjmp,
7358 the value read is indeterminate. Some local variables of type
7359 'struct handler' and 'struct catchtag' are used in this way, so
7360 mark each of their slots as volatile if the slot can be set before
7361 _longjmp and read afterwards.
7362 * lisp.h (struct handler): var and chosen_clause are now volatile.
7363 (struct catchtag): val, next, and pdlcount are now volatile.
7365 * bidi.c (bidi_push_it, bidi_pop_it):
7366 * fns.c (copy_hash_table):
7367 * image.c (define_image_type):
7368 * keyboard.c (kbd_buffer_store_event_hold):
7369 * process.c (Fprocess_send_eof):
7370 * xfaces.c (x_create_gc) [HAVE_NS]:
7371 * xgselect.c (xg_select):
7372 Prefer assignment to memcpy when either will do.
7374 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7375 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7376 time an item is removed. No need to mark this function 'inline';
7377 the compiler knows better than we do.
7379 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7381 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7382 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7383 to change_frame_size (Bug#12388).
7384 (windowDidResize:): Pass YES to updateFrameSize.
7386 * nsterm.h: Add delay parameter to updateFrameSize.
7388 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7390 Discard killed buffers from deleted window and frame objects.
7391 This reduces an amount of references to killed buffers and
7392 helps GC to reclaim them faster.
7393 * alloc.c (discard_killed_buffers): New function.
7394 (mark_object): Use it for deleted windows and frames.
7395 (mark_object): If symbol's value is set up for a killed buffer
7396 or deleted frame, restore its global binding.
7397 * data.c (swap_in_global_binding): Add GC notice.
7398 (swap_in_symval_forwarding): Use convenient set_blv_where.
7399 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7400 * window.h: ... to here.
7402 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7404 Convenient macro to check whether the buffer is live.
7405 * buffer.h (BUFFER_LIVE_P): New macro.
7406 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7407 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7409 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7411 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7412 composition cases (Bug#12364).
7414 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7415 overhang of succeeding glyphs overlapping box cursor.
7417 * w32term.c (x_draw_glyph_string): Likewise.
7419 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7421 Simplify, document, and port floating-point (Bug#12381).
7422 The porting part of this patch fixes bugs on non-IEEE platforms
7423 with frexp, ldexp, logb.
7424 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7426 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7427 support, by removing commented-out code and briefly listing the
7428 C89 functions excluded. The commented-out stuff was confusing
7429 maintenance, e.g., we thought we needed cbrt but it was commented out.
7430 (logb): Remove decl; no longer needed.
7431 (isfinite): New macro, if not already supplied.
7432 (isnan): Don't replace any existing macro.
7433 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7434 are present on all C89 platforms.
7435 (Ffrexp): Do not special-case zero, as frexp does the right thing
7437 (Flogb): Do not use logb, as it doesn't have the desired meaning
7438 on hosts that use non-base-2 floating point. Instead, stick with
7439 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7440 frexp, to avoid getting an unspecified result.
7442 * xdisp.c (Qinhibit_debug_on_message): Now static.
7444 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7446 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7447 NSBezierPath (Bug#12131).
7449 2012-09-10 Chong Yidong <cyd@gnu.org>
7451 * fns.c (Fdelq, Fdelete): Doc fix.
7453 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7455 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7456 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7458 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7460 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7461 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7464 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7466 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7467 left fringe if the window has a left margin. This avoids leaving
7468 traces of the cursor because its leftmost pixel is not drawn over.
7470 * dispnew.c (update_window_line): When the left margin area of a
7471 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7472 that screen line. (Bug#12277)
7474 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7476 Assume C89 or later for math functions (Bug#12381).
7477 This simplifies the code, and makes it a bit smaller and faster,
7478 and (most important) makes it easier to clean up signal handling
7479 since we can stop worring about floating-point exceptions in
7480 library code. That was a problem before C89, but the problem
7481 went away many years ago on all practical Emacs targets.
7482 * data.c, image.c, lread.c, print.c:
7483 Don't include <math.h>; no longer needed.
7484 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7485 might be autoconfigured, as that never happens.
7487 * doprnt.c (DBL_MAX_10_EXP):
7488 * print.c (DBL_DIG):
7489 Remove. C89 or later always defines these.
7490 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7491 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7492 (arith_error, domain_error, domain_error2):
7493 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7494 no longer needed -- we simply return what C returns. All uses removed.
7495 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7497 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7498 Remove. All uses expanded, as these macros are no longer used
7499 more than once and are now more trouble than they're worth.
7500 (Ftan): Use tan, not sin / cos.
7501 (Flogb): Assume C89 frexp.
7502 (fmod_float): Assume C89 fmod.
7503 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7504 (init_floatfns): Remove. All uses removed.
7506 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7508 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7509 compositeToPoint for OSX < 10.6 (Bug#12390).
7511 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7513 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7514 This produces more-accurate results.
7516 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7518 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7519 changes (Bug#12088).
7521 2012-09-08 Chong Yidong <cyd@gnu.org>
7523 * syntax.c (Fstring_to_syntax): Doc fix.
7525 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7527 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7528 in the internal border.
7529 (x_set_window_size): Remove static variables and their usage.
7530 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7531 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7532 Remove fringe/internal border adjustment (Bug#11052).
7533 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7534 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7535 (ns_fix_rect_ibw): Remove.
7536 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7537 (ns_dumpglyphs_box_or_relief): Ditto.
7538 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7540 (ns_dumpglyphs_image): Ditto.
7541 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7543 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7544 their usage. Add fringe_extended_p and its use as in other terms.
7545 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7546 scroll bar was removed.
7547 (updateFrameSize): New function.
7548 (windowDidResize): Move code to updateFrameSize and call it.
7550 * nsterm.h (EmacsView): Add updateFrameSize.
7552 2012-09-07 Chong Yidong <cyd@gnu.org>
7554 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7556 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7558 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7560 More signal-handler cleanup (Bug#12327).
7561 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7562 Problem introduced when merging patches. Noted by Eli Zaretskii in
7563 <http://bugs.gnu.org/12327#67>.
7564 * floatfns.c: Comment fix.
7565 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7566 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7567 and anyway the declaration is harmless even if SIGDANGER is not defined.
7568 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7569 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7570 source files not surprisingly expected syssignal.h to define, or
7571 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7572 Include <sys/ioctl.h>, for FIONREAD.
7573 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7574 This eliminates a problem whereby other files mysteriously had
7575 to include "syssignal.h" before including "systty.h" if they
7576 wanted to use "#ifdef SIGIO".
7578 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7580 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7582 * w32.c (sigemptyset): Empty the set.
7583 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7585 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7587 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7589 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7590 (mark_object): Likewise for frame objects.
7592 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7594 * syssignal.h (handle_on_main_thread): Always declare,
7595 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7596 This ports to platforms without HAVE_PTHREAD.
7598 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7600 Signal-handler cleanup (Bug#12327).
7601 Emacs's signal handlers were written in the old 4.2BSD style with
7602 sigblock and sigmask and so forth, and this led to some
7603 inefficiencies and confusion. Rewrite these to use
7604 pthread_sigmask etc. without copying signal sets around. Also,
7605 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7606 'signal', and instead use functions that do not attempt to take
7607 over the system name space. This patch causes Emacs's text
7608 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7609 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7610 Do not include <signal.h> or "syssignal.h", as these
7611 modules do not use signals.
7612 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7613 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7614 Do not include <signal.h>, as "syssignal.h" does that for us now.
7615 * atimer.c (sigmask_atimers): New function.
7616 (block_atimers, unblock_atimers): New functions,
7617 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7619 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7620 no longer needed here.
7621 * emacs.c (main): Inspect existing signal handler with sigaction,
7622 so that there's no need to block and unblock SIGHUP.
7623 * sysdep.c (struct save_signal): New member 'action', replacing
7624 old member 'handler'.
7625 (save_signal_handlers, restore_signal_handlers):
7626 Use sigaction instead of 'signal' to save and restore.
7627 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7628 New function. All users of 'signal' modified to use set_sighandler
7629 if they're writeonly, and to use sys_signal if they're read+write.
7630 (emacs_sigaction_init, forwarded_signal): New functions.
7631 (sys_signal): Remove. All uses replaced by calls to sigaction
7632 and emacs_sigaction_init, or by direct calls to 'signal'.
7633 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7634 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7635 all uses replaced by pthread_sigmask etc. calls.
7636 * syssignal.h: Include <signal.h>.
7637 (emacs_sigaction_init, forwarded_signal): New decls.
7638 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7639 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7640 (sigmask, sys_sigmask): Remove; no longer needed.
7641 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7642 (sigblock, sigunblock, sigfree):
7643 (sigsetmask) [!defined sigsetmask]:
7644 Remove. All uses replaced by pthread_sigmask.
7645 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7646 no longer need to be replaced, and its typical old uses
7647 are now done via emacs_sigaction_init and sigaction.
7648 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7649 (sys_sigdel): Remove; unused.
7650 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7652 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7654 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7655 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7657 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7659 Explicitly mark buffer_defaults and buffer_local_symbols.
7660 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7661 mark_local_symbols here.
7662 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7663 since special buffers aren't marked here any more.
7664 (allocate_buffer): Chain new buffer with all_buffers here...
7665 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7667 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7668 (syms_of_buffer): Remove staticpro of the above.
7669 (init_buffer_once): Set names for buffer_defaults and
7670 buffer_local_symbols.
7672 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7674 Use bool for booleans in font-related modules.
7675 * font.c (font_intern_prop, font_style_to_value)
7676 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7677 (generate_otf_features, font_check_otf_features, font_check_otf)
7678 (font_match_p, font_list_entities, font_at):
7679 * fontset.c (fontset_id_valid_p, reorder_font_vector
7680 (fontset_find_font, Fset_fontset_font)
7681 (face_suitable_for_char_p) [0]:
7682 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7683 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7684 (m17n_flt_initialized, ftfont_shape_by_flt):
7685 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7686 * nsfont.m (nsfont_draw):
7687 * w32font.c (w32font_draw):
7688 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7689 Use bool for booleans.
7690 * font.h: Adjust to above API changes.
7691 (struct font, struct font_driver, struct font_driver_list):
7692 Use bool for booleans.
7693 (struct font): Remove useless member encoding_type.
7695 * fontset.c, xftfont.c: Omit unnecessary static decls.
7697 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7699 * alloc.c (mark_object): Revert window marking code
7700 since it's unsafe for the Fset_window_configuration.
7702 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7704 Fix race conditions with signal handlers and errno (Bug#12327).
7705 Be more systematic about preserving errno whenever a signal
7706 handler returns, even if it's not in the main thread. Do this by
7707 renaming signal handlers to distinguish between signal delivery
7708 and signal handling. All uses changed.
7709 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7710 * data.c (deliver_arith_signal): Rename from arith_error.
7711 * dispnew.c (deliver_window_change_signal): Rename from
7712 window_change_signal.
7713 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7714 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7715 * keyboard.c (deliver_input_available_signal): Rename from
7716 input_available_signal.
7717 (deliver_user_signal): Rename from handle_user_signal.
7718 (deliver_interrupt_signal): Rename from interrupt_signal.
7719 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7720 (deliver_child_signal): Rename from sigchld_handler.
7721 * atimer.c (handle_alarm_signal):
7722 * data.c (handle_arith_signal):
7723 * dispnew.c (handle_window_change_signal):
7724 * emacs.c (handle_fatal_signal, handle_danger_signal):
7725 * keyboard.c (handle_input_available_signal):
7726 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7727 * process.c (handle_pipe_signal, handle_child_signal):
7728 New functions, with the actual signal-handling code taken from the
7729 original respective signal handlers, sans the sporadic attempts to
7730 preserve errno, since that's now done by handle_on_main_thread.
7731 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7732 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7733 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7735 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7736 Move initialization of main_thread to sysdep.c's init_signals.
7737 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7738 our usage, and simplifies the mainline code.
7739 (record_child_status_change): New static function, as a helper
7740 for handle_child_signal, and with most of the old child handler's
7742 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7743 (handle_child_signal): Use the above.
7744 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7745 Moved here from emacs.c.
7746 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7747 code moved here from emacs.c's main function.
7748 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7749 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7750 This lets callers save and restore errno properly.
7752 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7754 Remove redundant or unused things here and there.
7755 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7756 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7757 * editfns.c (Fcompare_buffer_substrings): Likewise.
7758 * frame.h (struct terminal, struct font_driver_list):
7759 Remove redundant declarations.
7760 * window.h (Qleft, Qright): Likewise.
7762 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7764 Do not mark objects from deleted buffers, windows and frames.
7765 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7766 (mark_object): Likewise for windows and frames.
7768 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7770 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7771 buffer_defaults and buffer_local_symbols as valid objects.
7772 Return special value to denote them.
7774 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7776 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7777 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7778 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7779 (file_name_absolute_p, Fsubstitute_in_file_name):
7780 (check_executable, check_writable, Ffile_accessible_directory_p)
7781 (Fset_file_selinux_context, Fdefault_file_modes)
7782 (Finsert_file_contents, choose_write_coding_system)

7785 * filelock.c (boot_time_initialized, get_boot_time)
7786 (get_boot_time_1, lock_file_1, within_one_second):
7787 * floatfns.c (in_float):
7788 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7789 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7790 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7791 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7792 * window.c (compare_window_configurations):
7793 Use bool for booleans.
7794 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7795 (Fdefault_file_modes): Now mode_t, not int, for modes.
7796 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7797 (internal_delete_file): Now returns void, not a (boolean) int,
7798 since nobody was looking at the return value.
7799 * lisp.h, window.h: Adjust to above API changes.
7801 * xdisp.c (set_message): Simplify and reindent last change.
7803 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7805 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7807 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7809 * eval.c (call_debugger): Make the function non-static so that we
7810 can call it from set_message.
7812 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7813 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7815 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7817 Give more-useful info on a fatal error (Bug#12328).
7818 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7819 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7820 of doing the work ourselves.
7821 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7822 do most of the work.
7823 (fatal_error_backtrace): New function, taken from the guts
7824 of the old fatal_error_signal, but with a new option to output
7826 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7827 info about the signal than just its number.
7828 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7829 * sysdep.c: Include <execinfo.h>
7830 (emacs_backtrace): New function, taken partly from the previous
7831 code of the 'die' function.
7832 (emacs_abort): Call fatal_error_backtrace rather than abort.
7834 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7836 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7837 eager (load-time) macro-expansion.
7838 * lisp.mk (lisp): Add macroexp.
7840 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7842 Simplify redefinition of 'abort' (Bug#12316).
7843 Do not try to redefine the 'abort' function. Instead, redo
7844 the code so that it calls 'emacs_abort' rather than 'abort'.
7845 This removes the need for the NO_ABORT configure-time macro
7846 and makes it easier to change the abort code to do a backtrace.
7847 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7848 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7849 Remove; sysdep.c's emacs_abort now takes its place.
7850 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7851 'abort' changed to use 'emacs_abort'.
7852 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7853 (abort) [!defined abort]: Rename to ...
7854 (emacs_abort): ... new name.
7855 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7856 the place of the old 'abort' in emacs.c.
7857 * w32.c, w32fns.c (abort): Do not #undef.
7858 * w32.c (emacs_abort): Rename from w32_abort.
7860 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7862 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7863 offsets[j].dv, since the y axis of the screen coordinates points
7864 down, while the y axis of the font definition coordinates points
7865 up. This fixes display of Arabic diacritics such as KASRA and
7866 KASRATAN. (Bug#11860)
7868 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7870 Be more systematic about _setjmp vs setjmp.
7871 * alloc.c (test_setjmp, mark_stack):
7872 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7873 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7874 (png_load, my_error_exit, jpeg_load):
7875 * process.c (send_process_trap, send_process):
7876 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7877 The underscored versions are up to 30x faster on some hosts.
7878 Formerly, the code used setjmp+longjmp sometimes and
7879 _setjmp+_longjmp at other times, with no particular reason to
7880 prefer setjmp+longjmp.
7882 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7884 Fix minor problem found by static checking.
7885 * buffer.c (Fdelete_all_overlays): Return nil.
7887 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7889 * buffer.c (Fdelete_all_overlays): New function.
7891 2012-09-03 Chong Yidong <cyd@gnu.org>
7893 * gtkutil.c: Add extern decl for Qxft.
7895 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7909 All callers changed.
7910 * eval.c (interactive_p): Omit always-true boolean argument
7911 EXCLUDE_SUBRS_P. All callers changed.
7912 * dispextern.h, lisp.h: Reflect above API changes.
7913 * firstfile.c (dummy): Use the address of 'main', whose signature
7914 won't change, instead of the address of 'initialize', whose
7915 signature just changed from int to bool.
7916 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7917 * msdos.c (fatal_error_in_progress): ... from here.
7918 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7920 (redisplay_internal, unwind_redisplay): Simply clear
7921 REDISPLAYING_P when unwinding, instead of saving its previous,
7922 always-false value and then restoring it.
7924 Clean up some extern decls.
7925 Mostly, this hoists extern decls out of .c files and into .h files.
7926 That way, we're more likely to catch errors if the interfaces change.
7927 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7928 declare xg_mark_data.
7929 * dispextern.h (x_frame_parm_handlers):
7931 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

7947 * xfont.c (x_clear_errors):
7948 * xterm.c (x_frame_parm_handlers):
7949 Remove now-redundant extern decls.
7950 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7951 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7953 * xfaces.c: Remove unnecessary static decls.
7954 * xterm.c (updating_frame): Remove decl of nonexistent object.
7956 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7957 when building globals.h, as the objects that are not built on
7958 this host are not needed to compile C files on this host.
7960 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7962 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7989 (set_intervals_multibyte_1, set_intervals_multibyte):
7990 * keyboard.c (decode_timer):
7991 Use bool for boolean.
7992 * intervals.h, lisp.h, systime.h: Reflect above API changes.
7993 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
7995 2012-09-02 Chong Yidong <cyd@gnu.org>
7997 * keymap.c (push_key_description): Print M-TAB as C-M-i
8000 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
8002 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

8010 2012-09-01 Eli Zaretskii <eliz@gnu.org>
8012 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8013 more than one grapheme cluster passed to the shaper: compute the
8014 offset adjustment values separately for each cluster. (Bug#11860)
8016 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8017 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8018 about implicit conversions from integer to pointer.
8020 2012-09-01 Daniel Colascione <dancol@dancol.org>
8022 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8023 system used too early.
8025 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8027 Better seed support for (random).

8060 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
8062 * menu.c: Include TERM_HEADER instead of listing all possible
8063 window-system headers.
8065 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
8068 * keyboard.c: Include TERM_HEADER instead of listing all possible
8069 window-system headers.
8071 * image.c: Include TERM_HEADER instead of listing all possible

8075 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8076 window system declarations.
8078 * frame.h: Move common functions here: set_frame_menubar,
8079 x_set_window_size, x_sync, x_get_focus_frame,
8080 x_set_mouse_position, x_set_mouse_pixel_position,
8081 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8105 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8107 Remove mark_ttys function and fix tty_display_info initialization.
8108 * lisp.h (mark_ttys): Remove prototype.
8109 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8110 to mark_ttys because all possible values of 'top_frame' slot are
8111 the frames which are reachable from Vframe_list.
8112 * term.c (mark_ttys): Remove.
8113 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8115 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8117 Change struct frame bitfields from unsigned char to unsigned.
8118 * frame.h (struct frame): Change type of 'display_preempted',

8120 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
8121 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
8122 bitfields from unsigned char to unsigned.

8135 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
8137 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8138 for GCC 4.7.1 x86-64.
8140 2012-08-30 Glenn Morris <rgm@gnu.org>
8142 * lread.c (init_lread): For out-of-tree builds, only add the
8143 source directory's site-lisp dir to the load-path if it exists,
8144 consistent with in-tree builds. (Bug#12302)
8146 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8148 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

8157 (addString:row:): Remove return self, declare return value as void.
8158 (addSplit): Remove return self, declare return value as void.
8159 (clicked:): Remove return self, declare return value as void.
8160 Set dialog_return to button_values[seltag]. Code formatting change.

8162 Code formatting change.
8163 (timeout_handler:): Set timer_fired to YES.
8164 (runDialogAt:): Set timer_fired to NO.
8165 Handle click on close button as quit.
8167 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8168 Add window_closed and button_values. Add void as return value for
8169 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8170 Add process_dialog as new member.
8172 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8174 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
8175 is not one of the heaps we manage. (Bug#12242)

8236 Use bool for boolean.
8237 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
8238 and remove last int (actually boolean) argument, which was always 0.
8239 All callers changed.
8240 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8241 * dispextern.h (struct composition_it): Use bool for boolean.
8242 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8243 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8244 * dired.c (file_name_completion):
8245 Use bool for boolean. (This was missed in an earlier change.)
8247 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8249 * window.c (Fset_window_configuration): Revert first part of
8252 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8254 * nsterm.h (NSPanel): New class variable dialog_return.
8256 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8257 Initialize dialog_return.
8258 (windowShouldClose:): Use stop instead of stopModalWithCode.
8259 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8260 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8262 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
8265 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

8277 Use bool for booleans.
8278 * dired.c (file_name_completion):

8280 Omit int (actually boolean) argument. It wasn't being used.
8282 * composite.h, lisp.h: Reflect above API changes.

8306 * fileio.c (Finsert_file_contents):
8307 Use bool for booleans.
8308 * coding.h, lisp.h: Reflect above API changes.
8309 * coding.c: Remove unnecessary static function decls.
8310 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8311 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8312 not a boolean 'int', since callers never look at the return value.
8313 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8314 * coding.h (decoding_buffer_size, encoding_buffer_size)
8315 (emacs_mule_string_char): Remove unused extern decls.
8316 (struct iso_2022_spec, struct coding_system):
8317 Use 'unsigned int : 1' for boolean fields, since there's more than one.
8318 (struct emacs_mule_spec): Remove unused field 'full_support'.
8319 All initializations removed.
8320 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8322 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8324 Fix spare memory change (Bug#12286).
8325 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8326 (valid_lisp_object_p): Likewise.
8328 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8330 * window.c (Fset_window_configuration): Record any window's old
8331 buffer if it's replaced (see Bug#8789). If the new current
8332 buffer doesn't appear in the selected window, go to its old
8335 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8337 Special MEM_TYPE_SPARE to denote reserved memory.
8338 * alloc.c (enum mem_type): New memory type.
8339 (refill_memory_reserve): Use new type for spare memory.
8340 This prevents live_cons_p and live_string_p from incorrect
8341 detection of uninitialized objects from spare memory as live.
8343 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8346 * Makefile.in (.PHONY): versioclean -> versionclean.
8348 Remove unused external symbols.
8349 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8350 * window.c (Qwindow_valid_p, decode_valid_window):
8351 Now static, not extern.
8352 * data.c (Qinterval): Remove; unused.
8353 (syms_of_data): Do not define 'interval'.
8354 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8355 * window.h (decode_valid_window):
8358 * character.c, charset.c, chartab.c: Use bool for booleans.
8359 * character.c (lisp_string_width, string_count_byte8)

8368 (char_table_set_range, optimize_sub_char_table)
8369 (map_sub_char_table):
8370 Use bool for boolean.
8371 * character.c (str_to_unibyte): Omit last boolean argument; it was
8372 always 0. All callers changed.
8373 * character.h, charset.h: Adjust to match previous changes.
8374 * character.h (char_printable_p): Remove decl of nonexistent function.
8375 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8376 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8377 are all boolean, so make them single-bit bitfields.
8379 * lisp.h (ASET): Remove attempt to detect side effects.
8380 It was meant to be temporary and it often doesn't work,
8381 because when IDX has side effects the behavior of IDX==IDX
8382 is undefined. See Stefan Monnier in
8383 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8385 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8387 * lisp.h (functionp): New function (extracted from Ffunctionp).
8388 (FUNCTIONP): Use it.
8389 * eval.c (Ffunctionp): Use it.
8391 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8393 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8394 as that's faster and simpler than static storage. Don't bother
8395 with the g_main_context_query overhead if g_main_context_pending
8396 says no events are pending.
8397 (gfds, gfds_size): Remove these static vars.
8398 (xgselect_initialize): Remove; no longer needed.
8399 All uses and decls removed.
8401 * emacs.c (fatal_error_signal_hook): Remove.
8402 All uses removed. This leftover from old code was always 0.
8404 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8405 * casefiddle.c (casify_object, casify_region):
8406 * casetab.c (set_case_table):
8407 * category.c, category.h (word_boundary_p):
8408 * category.h (CHAR_HAS_CATEGORY):
8409 Use bool for booleans, instead of int.
8411 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8413 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8415 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8417 On assertion failure, print backtrace if available.
8418 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8419 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8420 * Makefile.in (LIB_EXECINFO): New macro.
8423 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8424 * bytecode.c (exec_byte_code):
8425 * callint.c (check_mark, Fcall_interactively):
8426 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8427 (getenv_internal, sync_process_alive, call_process_exited):
8428 * lisp.h (USE_SAFE_ALLOCA):
8429 Use bool for booleans, instead of int.
8430 * lisp.h, process.h: Adjust prototypes to match above changes.
8431 * callint.c (Fcall_interactively): Don't assume the mark's
8432 offset fits in 'int'.
8434 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8436 * buffer.c, buffer.h: Use bool for boolean.
8437 * buffer.c (reset_buffer_local_variables)
8438 (buffer_lisp_local_variables, Fset_buffer_modified_p)
8439 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

8441 (overlay_touches_p, overlay_strings, Foverlay_put)
8442 (report_overlay_modification, call_overlay_mod_hooks):
8443 (mmap_enlarge, mmap_set_vars):
8444 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8445 Use bool for booleans, instead of int.
8446 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8447 since the 1-or-0 return value is always ignored anyway.
8448 (mmap_initialized_p):
8449 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8450 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8452 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8454 * bidi.c: Use bool for boolean.
8455 This is a bit more readable, and makes the text segment of bidi.o
8456 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8457 Presumably it's faster too.
8458 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8460 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8461 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8462 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8463 (bidi_explicit_dir_char, bidi_level_of_next_char)
8464 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8465 Use bool for booleans, instead of int.
8466 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8467 (bidi_unshelve_cache): Adjust decls to match code.
8469 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8471 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8474 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8476 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8477 * atimer.h: Include <stdbool.h>.
8479 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8481 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8482 compile time tests instead of run time tests on systems that do
8484 (FRAME_MAC_P): Remove leftover from deleted code.
8485 * frame.c (syms_of_frame): Remove leftover from deleted code.
8487 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8489 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8491 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8493 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8494 Otherwise, the compiler complains about (A?B:C) where B is void
8495 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8496 (fontset_add): Return void, for FONTSET_ADD.
8498 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8500 * alloc.c: Use bool for booleans.
8501 (gc_in_progress, abort_on_gc)
8502 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8503 (dont_register_blocks) [GC_MALLOC_CHECK]:
8504 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8505 (check_string_bytes, make_specified_string, memory_full)
8506 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8507 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8508 (mark_stack, valid_pointer_p, make_pure_string)
8509 (Fgarbage_collect, survives_gc_p, gc_sweep):
8510 Use bool for booleans, instead of int.
8511 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8512 Remove unused local.
8513 * alloc.c (PURE_POINTER_P):
8514 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8515 * editfns.c (Fformat):
8516 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8518 * fns.c (sweep_weak_table):
8519 * lisp.h (suppress_checking, push_message, survives_gc_p)
8520 (make_pure_string, gc_in_progress, abort_on_gc):
8521 * lread.c (readchar, read1):
8522 * print.c (Fprin1_to_string):
8523 * xdisp.c (push_message):
8524 Use bool for booleans affected directly or indirectly by
8527 Make recently-introduced setters macros.
8528 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8529 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8530 (set_fontset_default, set_fontset_fallback): Rename from their
8531 upper-case counterparts, and make them functions rather than macros.
8532 This is more consistent with the other recently-introduced setters.
8533 These don't need to be inline, since they're local.
8535 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8537 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8538 the loop (Bug#12247).
8540 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8542 * lisp.h (vcopy): Use memcpy rather than our own loop.
8543 This fixes a performance regression introduced by the recent
8544 addition of vcopy. This means 'vcopy' will need to be modified
8545 for a copying collector, but that's OK. Also, tighten the
8546 checking in the assertion.
8548 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8550 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8551 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8552 non-base glyph for the width of the base character, according to
8553 what x_draw_composite_glyph_string_foreground expects.
8554 Generate WADJUST value according to composition_gstring_width's
8555 expectations, to produce correct width of the composed character.
8556 Reverse the sign of the DU offset produced by ScriptPlace.
8558 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8560 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8562 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8564 Avoid direct writes to contents member of struct Lisp_Vector.
8565 * lisp.h (vcopy): New function to copy data into vector.
8566 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8567 * fns.c (Ffillarray): Use ASET.
8568 * keyboard.c (timer_check_2): Use AREF and ASET.
8569 (append_tool_bar_item, Frecent_keys): Use vcopy.
8570 * lread.c (read_vector): Use ASET.
8571 * msdos.c (Frecent_doskeys): Use vcopy.
8572 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8573 (Finternal_merge_in_global_face): Use ASET and vcopy.
8574 * xfont.c (xfont_list_pattern): Likewise.
8576 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8578 * window.c (Fwindow_point): For the selected window always return
8579 the position of its buffer's point.
8580 (Fset_window_point): For the selected window always go in its
8581 buffer to the specified position.
8583 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8585 Setter macros for fontsets.
8586 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8587 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8588 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8591 2012-08-20 Glenn Morris <rgm@gnu.org>
8593 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8594 Don't assume that `ln -f' works.
8596 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8598 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8599 and later about non-assignments with no effect. See discussion at
8600 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8603 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8605 Inline setter functions for Lisp_Objects slots of struct specbinding.
8606 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8609 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8611 * window.c (select_window): Always make selected window's buffer
8614 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8616 Use AREF and ASET for docstrings of category tables.
8617 * category.h (CATEGORY_DOCSTRING): Use AREF.
8618 (SET_CATEGORY_DOCSTRING): Use ASET.
8619 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8621 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8623 Inline setter functions for hash table members.
8624 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8625 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8626 (set_hash_key_and_value, set_hash_index, set_hash_next)
8627 (set_hash_hash): New functions.
8628 * charset.c, fns.c: Adjust users.
8630 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8632 Inline getter and setter functions for per-buffer values.
8633 * buffer.h (per_buffer_default, set_per_buffer_default)
8634 (per_buffer_value, set_per_buffer_value): New functions.
8635 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8636 * buffer.c, data.c: Adjust users.
8638 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8640 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8642 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8644 Rely on <config.h> + <unistd.h> to declare 'environ',
8645 as gnulib does this if the system doesn't.
8646 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8647 Remove declaration. MS-Windows declares it on stdlib.h which is
8648 included by conf_post.h.
8649 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8650 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8651 * vm-limit.c: Include <unistd.h>, for 'environ'.
8653 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8654 (start_of_data): Remove decl; mem-limits.h provides it.
8656 * xdisp.c (handle_invisible_prop): Make it a bit faster
8657 and avoid a gcc -Wmaybe-uninitialized diagnostic.

9070 Use bool, not int, for Lisp booleans.
9071 This is more natural, and on my platform (GCC 4.7.1 x86-64) it
9072 makes Emacs a bit smaller and presumably a bit faster.

9074 (struct Lisp_Boolfwd, defvar_bool):
9075 * lread.c (defvar_bool): Use bool, not int, for Lisp booleans.

9530 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9531 compatibility with Posix platforms.
9532 (main): Move the call to check_windows_init_file to here from
9534 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9535 any, in the DEFALT argument into the root of the Emacs build or
9536 installation tree, as appropriate.
9538 * callproc.c (init_callproc_1): Call decode_env_path instead of
9539 doing its equivalent by hand.
9540 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9541 the code that sets Vexec_path run on MS-Windows.
9543 * lread.c (init_lread): Add comments to #ifdef's.
9545 * msdos.c (dos_set_window_size, IT_update_begin)
9546 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
9547 instead of direct references.
9549 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
9551 Export DEFAULT_REHASH_* to GDB.
9552 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
9553 Now constants, not macros.
9555 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9557 Remove unnecessary casts involving pointers.
9558 These casts are no longer needed now that we assume C89 or later,
9559 since they involve casting to or from void *.
9560 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
9561 (make_pure_float, make_pure_vector):
9562 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9571 (x_get_window_property, x_get_window_property_as_lisp_data):
9572 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9573 Remove unnecessary pointer casts.
9574 * alloc.c (record_xmalloc): New function.
9575 * lisp.h (record_xmalloc): New decl.
9576 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9577 more like a function. This is because the pointer cast is not
9578 needed. All uses changed.
9579 * print.c (print_string, print_error_message): Avoid length recalc.
9581 Improve fix for macroexp crash with debugging (Bug#12118).
9582 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9583 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9584 not supposed to be invoked from the garbage collector.
9585 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9586 (gc_aset): New function, which is like ASET but can be
9587 used in the garbage collector.
9588 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
9589 (set_hash_index): Use it instead of ASET.

9600 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
9601 (map_w32_filename): Improve commentary. Simplify switch.
9602 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
9603 headers (most versions of MinGW w32api don't).
9604 (get_security_info, create_symbolic_link)
9605 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9607 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9608 in the argument file name.

9610 GetFileAttributes fails with network-related error codes.
9611 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9612 have the required privileges.
9613 (get_file_security_desc_by_name): Rename from
9614 get_file_security_desc.
9615 (stat_worker): New function, with most of the guts of 'stat', and
9616 with addition of handling of symlinks and support for 'lstat'.
9617 If possible, get file's attributes and security information by
9618 handle, not by name. Produce S_IFLNK bit for symlinks, when
9619 called from 'lstat'.
9620 (stat, lstat): New functions, call 'stat_worker'.
9621 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9622 symlinks when the underlying filesystem supports them.
9624 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9626 Fix macroexp crash on Windows with debugging (Bug#12118).
9627 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9628 checking subscripts; problem introduced with the recent
9629 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9630 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9631 since it's used in non-static inline functions now.
9633 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9634 Don't assume buffer size fits in 'int'. Remove unused local.
9636 Use C99-style 'extern inline' if available.

9648 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
9649 * alloc.c (LISP_INLINE):
9650 * buffer.c (BUFFER_INLINE):
9651 * category.c (CATEGORY_INLINE):
9652 * character.c (CHARACTER_INLINE):
9653 * charset.c (CHARSET_INLINE):
9654 * composite.c (COMPOSITE_INLINE):
9655 * dispnew.c (DISPEXTERN_INLINE):
9656 * sysdep.c (SYSTIME_INLINE):
9657 Define to EXTERN_INLINE, so that the corresponding functions
9658 are compiled into code.
9659 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9660 (INLINE_HEADER_END): New macros.
9661 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9681 hard-coding the path separator.
9683 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9685 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9686 This how ASET and AREF are supposed to work, and makes
9687 it easier to think about future improvements. See
9688 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9689 * charset.h (set_charset_attr): New function.
9690 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
9691 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

10104 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10105 enumeration constants, as PURE and HEAP are too general, and clash
10106 with other headers and sources, such as gmalloc.c and the
10107 MS-Windows system headers. All users changed.
10109 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10111 Revert last save_excursion_save and save_excursion_restore changes.
10112 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

10122 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10124 Improve GDB symbol export (Bug#12036).
10125 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10126 arms of an 'if', not using conditional expressions; otherwise GDB
10127 complains about the types in the unevaluated arm when the argument
10128 is an integer literal.
10129 (xgetint): Simplify expression.
10130 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10131 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10132 Zaretskii in <http://bugs.gnu.org/12036#13>.
10133 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10134 needed now that we have gdb_make_enums_visible.
10135 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10136 (enum enum_USE_LSB_TAG):
10137 New enum types, packaging up enums that need to be exported to GDB.
10139 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10141 Utility function to make a list from specified amount of objects.
10142 * lisp.h (enum constype): New datatype.

10162 (PVEC_EXCURSION): New pseudovector type.
10163 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10164 to deal with it. Adjust comments.
10165 (init_marker, attach_marker): New prototype.
10166 (unchain_marker): Adjust prototype.
10167 * marker.c (attach_marker): Change to global.

10178 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10179 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10180 emacs.c, as this is a more-suitable home. Had this been done earlier
10181 the fix for 12036 would have avoided some of the problems noted in
10182 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10183 would have been more obvious.
10184 * emacs.c: Do not include <verify.h>; no longer needed.
10185 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

10187 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10188 Remove; now done in lisp.h.
10189 * lisp.h (PUBLISH_TO_GDB): New macro.

10192 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10193 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10194 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10195 not be usable in #if. This simplifies things.
10197 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10199 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10201 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10203 Simplify export of symbols to GDB (Bug#12036).
10204 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10205 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10206 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10207 Adjust to changes in lisp.h and emacs.c, by using
10208 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10209 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10210 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10211 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10212 instead of gdb_valbits.
10213 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10214 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10215 instead of gdb_array_mark_flag.
10216 (xboolvector): Get size from $->size, not $->header.size.
10217 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10218 (xreload, hook-run, hookpost-run): Remove.
10219 * emacs.c: Include <verify.h>.
10220 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10221 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10223 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10224 (gdb_USE_LSB_TAG): New enum constants.
10225 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10226 Also define these as enum constants, so they're visible to GDB.
10227 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10228 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10229 as constants, so they're visible to GDB.
10230 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10231 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10232 Now enum constants, not macros, so they're visible to GDB.
10233 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10234 more convenient now. All uses changed.
10235 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10236 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10238 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10240 Explicitly free restriction data that are not needed anymore.
10241 * editfns.c (save_restriction_restore): Free restriction data.
10243 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10245 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10246 add argument, tune behavior, and adjust all callers.
10248 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10250 Use typedef for EMACS_INT, EMACS_UINT.
10251 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10252 than macros. This simplifies debugging in the usual case, since
10253 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10254 and it allows expressions involving EMACS_INT casts.
10255 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10257 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10259 * nsterm.m (ns_read_socket): Return early if there is a modal

10265 that FOCUS-FRAME can be omitted.
10267 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10269 Adjust buffer text indirection counters at the end of Fkill_buffer.
10270 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10271 buffer is definitely dead. This should really fix an issue reported
10272 by Christoph Scholtes again. (Bug#12007).
10273 (init_buffer_once): Initialize indirection counters of
10274 buffer_defaults and buffer_local_symbols (for sanity and safety).
10276 2012-07-24 Eli Zaretskii <eliz@gnu.org>

10291 or invalid. (Bug#12025)
10293 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10294 it signals an error when a tooltip frame is being created.
10296 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10298 Cleanup miscellaneous objects allocation and initialization.
10299 * alloc.c (allocate_misc): Change to static. Add argument to
10300 specify the subtype. Adjust comment and users.
10301 (build_overlay): New function.
10302 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10303 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
10304 (allocate_misc): Remove prototype.
10305 (build_overlay): Add prototype.
10307 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10309 Swap buffer text indirection counters in Fbuffer_swap_text.
10310 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10311 This avoids crash reported by Christoph Scholtes at
10312 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10314 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10316 * nsmenu.m (Popdown_data): New struct.
10317 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
10319 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
10320 (initWithContentRect): Make imgView and contentView non-static
10321 and autorelease them. Also autorelease img and matrix (Bug#12005).
10322 (dealloc): Remove (Bug#12005).
10324 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10326 Adjust consing_since_gc when objects are explicitly freed.
10327 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.

10336 (Fset_marker, set_marker_restricted): Use set_marker_internal.
10337 (set_marker_both, set_marker_restricted_both): Use live_buffer.
10339 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
10341 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
10342 as it's limited by the amount of memory, not by INT_MAX.
10344 2012-07-21 Eli Zaretskii <eliz@gnu.org>
10346 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

10892 and continuation glyphs alike.
10893 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
10894 glyph of a suitably computed width, to align the special glyphs at

11070 * s/aix4-2.h (unix): Remove; no longer needed.
11072 EMACS_TIME simplification (Bug#11875).
11073 This replaces macros (which typically do not work in GDB)

11075 The functional style also makes code easier to read and maintain.
11076 * systime.h: Include <sys/time.h> on all hosts, not just if
11077 WINDOWSNT, since 'struct timeval' is needed in general.
11078 (EMACS_TIME): Now a typedef, not a macro.

11112 (menu_separator_name_p):
11113 * nsmenu.m (ns_update_menubar):
11114 Prefer memcmp to strncmp when either will do.
11115 * nsterm.m: Include <ftoastr.h>.
11117 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11118 Prefer snprintf to strncpy.
11119 * nsterm.m (ns_term_init):
11120 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11121 * nsterm.m (ns_term_init):
11122 Avoid the need for strncpy, by using build_string or
11123 make_unibyte_string directly. Use dtoastr, not snprintf.
11124 * process.c (Fmake_network_process): Diagnose service names that
11125 are too long, rather than silently truncating them or creating
11126 non-null-terminated names.
11127 (Fnetwork_interface_info): Likewise, for interface names.
11128 * sysdep.c (system_process_attributes) [GNU_LINUX]:
11129 Prefer sprintf to strncat.

11142 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
11143 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

11159 provides a better opportunity to optimize away calls to strlen when
11160 the function is called with compile-time constant argument.
11161 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11162 argument, adjust users accordingly. Use build_pure_c_string where

11165 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11166 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

11196 We include usg5-4-common.h, which defines them both.
11198 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11199 O_RDONLY already includes it).
11201 Stop ns builds setting the EMACSLOADPATH environment variable.
11202 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11203 Now it does not set EMACSLOADPATH, just returns the load-path string.
11204 * nsterm.h: Update accordingly.
11205 * lread.c [HAVE_NS]: Include nsterm.h.
11206 (init_lread) [HAVE_NS]: Use ns_load_path.

11216 (ns_init_paths): Do not set EMACSPATH.

11245 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11247 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

11272 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11274 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11276 Move marker debugging code under MARKER_DEBUG.
11277 * marker.c (MARKER_DEBUG): Move marker debugging code under
11278 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11279 for bootstrap with --enable-checking (~3x slowdown reported
11280 by Juanma Barranquero <lekktu@gmail.com>).
11281 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11283 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11285 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11286 See <http://bugs.gnu.org/11825#29>.
11288 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11290 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11291 has no font, use the frame's font. (Bug#11813)
11292 (display_line): Add commentary about displaying truncation glyphs
11294 (produce_special_glyphs): Move here from term.c.
11296 * term.c (produce_special_glyphs): Move to xdisp.c.
11298 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11301 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11303 * xdisp.c (display_line): Avoid warning about implicit declaration
11306 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11308 * lisp.h: Remove empty conditional.
11310 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11312 * lread.c (load_path_check): Now static.
11314 Fix some minor --with-ns problems found by static checking.
11315 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11316 (x_set_font) [!HAVE_X_WINDOWS]:
11317 * image.c (xpm_load_image) [HAVE_NS]:
11318 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11319 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11320 Remove unused local.
11321 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11322 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11323 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11324 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11325 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11326 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11327 Fix pointer signedness problem.
11328 * xfaces.c (FRAME_X_FONT_TABLE):
11329 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11331 2012-07-07 Glenn Morris <rgm@gnu.org>
11333 * lread.c (load_path_check): New function, split from init_lread.
11334 (init_lread): Reorganize. Motivation:
11335 If EMACSLOADPATH is set, check/warn about that rather than the
11336 defaults, which we are not going to use. Hence we can remove
11337 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11338 Don't warn if site-lisp directories are missing.
11339 If not installed, start from a blank load-path, since
11340 PATH_LOADSEARCH refers to the eventual installation directories.
11342 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11344 Support truncation and continuation glyphs on GUI frames, when
11345 fringes are disabled. (Bug#11832)
11346 * xdisp.c (init_iterator): Get dimensions of truncation and
11347 continuation glyphs even if on GUI frames.
11348 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11349 or both, are absent.
11350 (start_display, move_it_in_display_line_to): Handle the case of a
11351 GUI frame without a fringe to display continuation or truncation
11353 (insert_left_trunc_glyphs): Support GUI frames: make sure
11354 truncation glyphs overwrite enough glyphs from the current line to
11355 have sufficient space in pixels.
11356 (display_line): Support truncation and continuation glyphs on GUI
11357 frames. If some spare pixels are left on the line after inserting
11358 the truncation glyphs, fill that space with a stretch glyph of a
11359 suitably computed width.
11361 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11362 produce_glyphs, to support GUI sessions.
11364 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11366 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11368 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11370 Do not require float-time's arg to fit in time_t (Bug#11825).
11371 This works better on hosts where time_t is unsigned, and where
11372 float-time is applied to the (negative) difference between two times.
11373 * editfns.c (decode_time_components): Last arg is now double *,
11374 not int *, and means to store all the result as a double, without
11375 worrying about whether the seconds part fits in time_t.
11376 All callers changed.
11377 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11378 All callers changed.
11379 (Ffloat_time): Do not fail merely because the specified time falls
11380 outside of time_t range.
11382 2012-07-07 Glenn Morris <rgm@gnu.org>
11384 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11385 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11386 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11388 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11390 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11391 Update dependencies.

11399 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11400 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11401 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11402 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11404 * xfont.c (compare_font_names): Redo to omit the need for casts.
11406 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11408 * xfns.c (Fx_change_window_property): Doc fix.
11409 * w32fns.c (Fx_change_window_property): Doc fix.
11411 * w32fns.c (Fx_window_property): Accept the same arguments as the
11412 X Windows version. Doc fix.
11413 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11415 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11416 Eli Zaretskii <eliz@gnu.org>
11418 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11419 Windows-specific code from nt/config.nt moved here.
11420 Obsolete settings removed.
11422 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11424 * process.c: Avoid unnecessary calls to gettime.
11425 (wait_reading_process_output): Don't get the time of day
11426 when gobbling data immediately and not waiting, as there's no need
11427 for it in that case. This removes a FIXME.
11429 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11431 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11432 is defined (Bug#11768).
11434 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11436 Fix marker debugging code.
11437 * marker.c (byte_char_debug_check): Do not perform the check
11438 if buffer is not multibyte.
11439 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11440 Call byte_char_debug_check with correct arguments.
11442 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11444 Compile marker debugging code only if ENABLE_CHECKING is defined.
11445 * marker.c (byte_char_debug_check, count_markers):
11446 Use only if ENABLE_CHECKING is defined.
11447 (byte_debug_flag): Remove.
11448 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11449 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11451 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11453 Avoid code repetition in marker-related functions.
11454 * marker.c (attach_marker): New function.

11458 Consistently rename charno to charpos.
11459 (marker_position): Add eassert.
11460 (marker_byte_position): Convert to eassert.

11476 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11477 (save_restriction_save): Use build_marker.
11478 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11479 * window.c (save_window_save): Likewise.
11481 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11483 Do not use Fdelete_overlay in delete_all_overlays
11484 to avoid redundant calls to unchain_overlay.
11485 * buffer.c (drop_overlay): New function.
11486 (delete_all_overlays, Fdelete_overlay): Use it.
11487 * minibuf.c (get_minibuffer): Fix comment.
11489 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11491 Port to OpenBSD 5.1 amd64.
11492 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11493 This is needed for OpenBSD, and should be harmless on all BSD systems.
11494 Also, include <sys/sysctl.h>, as it should be available on all
11495 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11496 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11497 use p_pid member, not kp_proc.pid.
11499 2012-07-06 Glenn Morris <rgm@gnu.org>
11501 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11503 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11505 More xmalloc and related cleanup.
11506 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

11514 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11516 Omit needless casts involving void * pointers and allocation.
11517 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11518 as the former is more robust if P's type is changed.
11519 Prefer xzalloc to xmalloc + memset 0.
11520 Simplify malloc-or-realloc to realloc.
11521 Don't worry about xmalloc returning a null pointer.
11522 Prefer xstrdup to xmalloc + strcpy.
11523 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11525 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11526 alloca of a constant.
11528 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11530 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11531 hscroll is larger than the line width. Fixes long and futile
11532 looping inside extend_face_to_end_of_line (on a TTY) producing
11533 glyphs that are not needed and thrown away.
11535 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11537 * marker.c (set_marker_restricted_both): Simplify by using
11540 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

11551 followed by gtk_box_set_homogeneous (Bug#11768).
11552 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11553 (update_theme_scrollbar_width, xg_create_scroll_bar):
11554 Use gtk_scrollbar_new (Bug#11768).

11556 (is_box_type): New function (Bug#11768).
11557 (xg_tool_item_stale_p): Call is_box_type.
11558 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11559 with default display (Bug#11768).
11561 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11563 * xdisp.c (window_hscroll_limited): New function.
11564 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11565 coordinates when window's hscroll is set to insanely large
11566 values. (Bug#11857)
11568 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11632 Problem reported by Troels Nielsen in
11633 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11635 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11637 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11638 This should be fixed in a better way; see Eli Zaretskii in
11639 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11640 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11642 * fileio.c (time_error_value): Rename from special_mtime.
11643 The old name's problems were noted by Eli Zaretskii in
11644 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11646 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11647 This variable's comment says Emacs needs at least one GDB-visible
11648 symbol of type enum pvec_type, to work around GDB problems.
11649 The symbol's value doesn't matter.
11651 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11652 that causes compilation to fail on pre-C99 compilers.
11654 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11656 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11657 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11659 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11661 * buffer.c (init_buffer_once): Fix initialization of
11662 headers for buffer_defaults and buffer_local_symbols.
11663 Reported by Juanma Barranquero <lekktu@gmail.com>.
11665 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>

11680 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11681 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11682 abusing vector->header.next.nbytes.
11683 (live_vector_p): Use PVEC_TYPE.
11684 (mark_object): Adapt code to extract pvectype. Use switch.
11686 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11688 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11689 Tighten new eassert a bit.
11691 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11693 Fix compilation with --enable-gcc-warnings and -O1
11694 optimization level.
11695 * doprnt.c (doprnt): Change type of tem to int, initialize
11696 to avoid compiler warning. Add eassert.
11697 * search.c (simple_search): Initialize match_byte to avoid
11698 compiler warning. Add eassert.
11700 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11702 Avoid weird behavior with large horizontal scrolls.
11703 Without this change, for example, large hscroll values would
11704 mess up Emacs's display on Fedora 15 x86, presumably due to
11705 overflows in int calculations in the display code.
11706 Also, if buffers had long lines, Emacs would freeze.
11707 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11708 (set_window_hscroll): New function, containing the old guts of
11709 Fset_window_hscroll. Return the clipped value.
11710 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11711 This avoids the need to check against PTRDIFF_MAX.
11713 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11715 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11717 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11719 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11721 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11722 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11723 since GCC 4.4.6 issues a bogus warning for them.
11725 Fix bugs in file timestamp newness comparisons.
11726 * fileio.c (Ffile_newer_than_file_p):
11727 * lread.c (Fload): Use full timestamp resolution of files,
11728 not just the 1-second resolution, so that files that are only
11729 slightly newer still count as newer.
11730 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11731 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11733 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11735 * fileio.c: Improve handling of file time marker. (Bug#11852)
11736 (special_mtime): New function.
11737 (Finsert_file_contents, Fverify_visited_file_modtime):
11738 Use it to set special mtime values consistently.
11740 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11742 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11743 marker for non-existing file. (Bug#11852)
11745 2012-07-03 Glenn Morris <rgm@gnu.org>
11747 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11748 and did not make it into globals.h).
11750 2012-07-03 Tom Tromey <tromey@redhat.com>
11752 * window.c (Fset_window_margins, Fset_window_fringes)
11753 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11754 * textprop.c (Fprevious_property_change): No longer static.
11755 * syntax.c (Fsyntax_table_p): No longer static.
11756 * process.c (Fget_process, Fprocess_datagram_address): No longer

11779 * font.h: Remove EXFUNs.
11780 * dosfns.c (system_process_attributes): Remove EXFUN.
11781 * keymap.h: Remove EXFUNs.
11782 * lisp.h: Remove EXFUNs.
11783 * w32term.h: Remove EXFUNs.
11784 * window.h: Remove EXFUNs.
11785 * xsettings.h: Remove EXFUN.
11786 * xterm.h: Remove EXFUN.
11788 2012-07-03 Glenn Morris <rgm@gnu.org>
11790 * lisp.h (Frandom): Make it visible to C.
11791 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11792 buffer for invisible buffers. (Bug#1229)
11794 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11796 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11797 values which aren't power of 2.
11798 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11799 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11802 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11804 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11806 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11808 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11810 * alloc.c (allocate_vector_block): Remove redundant
11811 calls to mallopt if DOUG_LEA_MALLOC is defined.
11812 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11813 avoid calls to mallopt if zero_vector is returned.
11815 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11817 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11818 is enabled, avoid dereferencing NULL current_sblock if
11821 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11823 Cleanup basic buffer management.
11824 * buffer.h (struct buffer): Change layout to use generic vector
11825 marking code. Fix some comments. Change type of 'clip_changed'
11826 to bitfield. Remove unused #ifndef old.
11827 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11828 (GET_OVERLAYS_AT): Fix indentation.
11829 (for_each_per_buffer_object_at): New macro.
11830 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11831 (Fbuffer_local_variables): Use it.
11832 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11833 * alloc.c (allocate_buffer): Adjust to match new layout of
11834 struct buffer. Fix comment.
11835 (mark_overlay): New function.
11836 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11837 Lisp area of struct buffer.
11838 (mark_object): Use it. Adjust marking of misc objects
11839 and related comments.
11841 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11843 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11844 wrapper that is not needed because the wrapped code is a no-op (zero
11845 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11846 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11848 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11850 * alloc.c (mark_buffer): Simplify. Remove prototype.
11851 (mark_object): Add comment. Reorganize marking of vector-like
11852 objects. Use CHECK_LIVE for all vector-like objects except buffers
11853 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11854 Avoid redundant calls to mark_vectorlike for bool vectors.
11856 2012-06-30 Glenn Morris <rgm@gnu.org>
11858 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11860 * epaths.in (PATH_SITELOADSEARCH): New.
11861 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11862 This is rather than relying on --enable-locallisppath elements
11863 having "site-lisp" in their names. (Bug#10208#25, 11658)
11865 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11867 * w32proc.c (sys_select): Accept and ignore one more argument.
11869 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11871 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11872 (pselect) [!MS_DOS]: Redirect to sys_select.
11874 * sysdep.c: Don't include dos.h and dosfns.h.
11876 * process.c (sys_select):
11877 * msdos.c (sys_select): Accept one more argument and ignore it.
11879 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11880 adapt data types and code to that.
11883 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11884 which clashes with the gnulib function of the same name.
11886 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11888 * font.c (font_style_to_value, font_style_symbolic)
11889 (font_prop_validate_style): Add type checks for values in
11892 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11894 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11897 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11899 * xdisp.c (try_window_id): Undo last change.
11901 * w32.c (getwd): Adjust commentary about startup_dir.
11902 (init_environment): Always call sys_access, even in non-MSVC
11903 builds. Don't chdir to the directory of the Emacs executable.
11904 This undoes code from 1997 which was justified by the need to
11905 "avoid conflicts when removing and renaming directories". But its
11906 downside was that every relative file name was being interpreted
11907 relative to the directory of the Emacs executable, which can never
11908 be TRT. In particular, it broke sys_access when called with
11909 relative file names.
11910 (sys_access): Map GetLastError to errno.
11912 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11914 * window.h (struct window): Change type of 'fringes_outside_margins'
11915 to bitfield. Fix comment. Adjust users accordingly.
11916 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11918 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11921 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11923 * gnutls.c (emacs_gnutls_handshake):
11924 Add QUIT to make the loop interruptible.
11926 2012-06-29 Glenn Morris <rgm@gnu.org>
11928 * charset.c (init_charset): Make lack of etc/charsets fatal.
11930 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11934 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11936 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11937 undefined. Convert from xassert to eassert.
11938 * nsmenu.m: Convert from xassert to eassert.
11939 * nsterm.m: Likewise.
11941 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11943 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11945 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11947 Avoid integer overflow on scroll-left and scroll-right.
11948 * window.c (HSCROLL_MAX): New macro.
11949 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11950 overflow when requested scroll falls outside ptrdiff_t range.
11952 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11954 * window.h (struct window): Change type of 'hscroll',
11955 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11956 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11957 Adjust users accordingly.
11958 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11959 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11960 from EMACS_INT to ptrdiff_t.
11961 (make_window): Omit redundant initialization.

11980 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11981 adjust comments accordingly.

12030 * alloc.c (allocate_string_data): Remove dead code.

12036 * alloc.c (allocate_string): Omit intervals initialization.

12063 when building with Clang.

12094 * alloc.c: Remove build_string.

12102 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12104 Use sprintf return value instead of invoking strlen on result.
12105 In the old days this wasn't portable, since some sprintf
12106 implementations returned char *. But they died out years ago and
12107 Emacs already assumes sprintf returns int.
12108 Similarly for float_to_string.
12109 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
12110 * ccl.c (ccl_driver):
12111 * character.c (string_escape_byte8):

12114 * print.c (print_object):
12115 * xdisp.c (message_dolog):
12116 * xfns.c (syms_of_xfns):
12117 Use sprintf or float_to_string result to avoid need to call strlen.
12118 * data.c (Fnumber_to_string):
12119 Use make_unibyte_string, since the string must be ASCII.
12120 * lisp.h, print.c (float_to_string): Now returns int length.
12121 * term.c (produce_glyphless_glyph):
12122 Use sprintf result rather than recomputing it.
12124 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12125 * Makefile.in (ALL_CFLAGS):
12126 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

12131 * dispextern.h (xstrcasecmp): Define to library function
12132 strcasecmp if available.

12151 sprintf already null-terminates its output.
12153 * xfns.c (x_window): Remove redundant cast.
12155 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12157 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
12158 `const char *' to `char *' to avoid compiler warning.
12160 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12162 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12163 instead of truncating it to 63 (admittedly a generous limit).
12165 * process.c: Fix spelling and caps in comments.
12167 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
12169 * emacs.c (setpgrp): Remove definition, unused.

12222 * dispnew.c (Fsleep_for, sit_for):
12223 * keyboard.c (kbd_buffer_get_event):
12224 * process.c (Faccept_process_output):
12225 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12226 This improves on the previous patch, which introduced a bug
12227 when time_t is unsigned and as wide as intmax_t.
12228 See <http://bugs.gnu.org/9000#51>.

12259 language ID in the event parameters.
12261 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12262 event.code, not the obscure "character set ID".

12293 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12295 Support higher-resolution time stamps (Bug#9000).
12296 The time stamps are only nanosecond-resolution at the C level,
12297 since that's the best that any real-world system supports now.
12298 But they are picosecond-resolution at the Lisp level, as that's
12299 easy, and leaves room for future OS improvements.
12301 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12304 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12305 Don't get current time unless it's needed.
12307 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12308 now provides it if it's absent.
12309 (start_atimer): Port to higher-res time stamps.
12310 Check for time stamp overflow. Don't get current time more
12311 often than is needed.
12313 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12314 Include systime.h, not time.h.
12315 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12317 * dired.c: Include stat-time.h.
12318 (Ffile-attributes): File times now have higher resolution.
12320 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12321 (struct image): Timestamp now has higher resolution.
12323 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12324 has at least microseconds now. All uses removed.
12325 (update_frame, update_single_window, update_window, update_frame_1)
12326 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12327 (duration_to_sec_usec): Remove; no longer needed.
12329 * editfns.c (time_overflow): Now extern.
12330 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12331 (float-time, Fformat_time_string, Fcurrent_time_string)

12335 (decode_time_components, lisp_seconds_argument): New functions.
12336 (make_time): Now static.
12337 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12338 Report an error if the time is invalid, rather than having the caller
12341 * fileio.c: Include <stat-time.h>
12342 (Fcopy_file): Copy higher-resolution time stamps.
12343 Prefer to set the time stamp via a file descriptor if that works.
12344 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12345 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12346 (Fvisited_file_modtime, Fset_visited_file_modtime):
12347 Support higher-resolution time stamps.
12349 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12351 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12353 * image.c (prepare_image_for_display, clear_image_cache)
12354 (lookup_image): Port to higer-resolution time stamps.
12356 * keyboard.c (start_polling, bind_polling_period):
12357 Check for time stamp overflow.
12358 (read_char, kbd_buffer_get_event, timer_start_idle)
12359 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12360 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12361 Port to higher-resolution time stamps. Do not assume time_t is signed.
12362 (decode_timer): New function. Timers are now vectors of length 9,
12363 not 8, to accommodate the picosecond component.
12364 (timer_check_2): Use it.
12366 * nsterm.m (select_timeout, timeval_subtract): Remove.
12367 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12368 as they're a bit more accurate and handle overflow better.
12369 (ns_select): Change prototype to be compatible with pselect.
12370 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12371 * nsterm.h (ns_select): Adjust prototype.
12373 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12374 us-resolution time stamps.
12375 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12377 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12379 * lisp.h (time_overflow): New decl.
12380 (wait_reading_process_output): First arg is now intmax_t, not int,
12381 to accommodate larger waits.
12383 * process.h (struct Lisp_Process.read_output_delay):
12384 Now counts nanoseconds, not microseconds.
12385 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12387 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12388 (wait_reading_process_output):
12389 Port to ns-resolution time stamps.
12390 (Faccept_process_output, wait_reading_process_output):
12391 Check for time stamp overflow. Do not assume time_t is signed.
12392 (select_wrapper): Remove; we now use pselect.
12393 (Fprocess_attributes): Now generates ns-resolution time stamps.
12395 * sysdep.c: Include utimens.h. Don't include utime.h
12396 or worry about struct utimbuf; gnulib does that for us now.
12397 (gettimeofday): Remove; gnulib provides a substitute.
12398 (make_timeval): New function.
12399 (set_file_times): Now sets ns-resolution time stamps.
12400 New arg FD; all uses changed.
12401 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12402 (system_process_attributes):
12403 Now returns ns-resolution time stamp. All uses changed.
12404 Check for time stamp overflow.
12406 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12407 provides a substitute now.
12409 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12410 since it guarantees struct timespec.
12411 (EMACS_TIME): Now struct timespec, so that we can support
12412 ns-resolution time stamps.
12413 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12414 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12415 (EMACS_USECS): Remove.
12416 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12417 so multiply the arg by 1000 before storing it.
12418 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12420 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12421 Port to ns-resolution time stamps.
12422 (EMACS_TIME_NEG_P): Remove; replaced by....
12423 (EMACS_TIME_SIGN): New macro.

12425 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12426 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12427 (make_timeval, make_lisp_time, decode_time_components): New decls.
12428 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12429 that it mishandled time_t overflow. You can't compare by subtracting!
12430 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12431 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12433 * term.c: Include <sys/time.h>.
12434 (timeval_to_Time): New function, for proper overflow wraparound.
12435 (term_mouse_position, term_mouse_click): Use it.
12437 * undo.c (record_first_change): Support higher-resolution time stamps
12438 in the undo buffer.
12439 (Fprimitive_undo): Use them when restoring time stamps.
12441 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12442 (w32_get_internal_run_time):
12443 Port to higher-resolution Emacs time stamps.
12444 (ltime): Now accepts single 64-bit integer, as that's more convenient
12447 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12449 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12450 for compatibility with pselect. Support ns-resolution time stamps.
12452 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12454 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12455 Check for time stamp overflow, and support ns-resolution time stamps.
12457 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12458 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12459 (timeval_subtract): Remove; no longer needed.
12460 (XTflash, XTring_bell, x_wait_for_event):
12461 Port to ns-resolution time stamps. Don't assume time_t is signed.
12463 2012-06-22 Chong Yidong <cyd@gnu.org>

12467 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12469 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12470 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12471 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12472 staticidx goes up to 1597 out of 1600 = 0x640.)
12474 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12476 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12477 Otherwise, the umask might be mistakenly 0 while handling input signals.
12479 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
12481 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

12488 access to `contents' member of Lisp_Vector objects with AREF and ASET
12491 2012-06-19 Chong Yidong <cyd@gnu.org>
12493 * frame.c (delete_frame): When selecting a frame on a different
12494 text terminal, do not alter the terminal's top-frame.
12496 * xdisp.c (format_mode_line_unwind_data): Record the target
12497 frame's selected window and its terminal's top-frame.
12498 (unwind_format_mode_line): Restore them.
12499 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12501 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12502 since tty frames can be explicitly named.
12503 (prepare_menu_bars): Likewise.
12505 * term.c (Ftty_top_frame): New function.
12507 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12510 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12511 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12512 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12513 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
12514 (METER_1, METER_2): Simplify.
12516 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
12518 * data.c (Fdefalias): Return `symbol' (bug#11686).
12520 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12522 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12523 gets killed during executing of this function (Bug#11665).
12524 Try to always return Qt when the buffer has been actually killed.
12525 (Vkill_buffer_query_functions): In doc-string say that functions
12526 run by this hook should not change the current buffer.
12528 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12530 Fix recently-introduced process.c problems found by static checking.
12531 * process.c (write_queue_push, write_queue_pop, send_process):
12532 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12533 (write_queue_pop): Fix pointer signedness problem.
12534 (send_process): Remove unused local.
12536 2012-06-17 Chong Yidong <cyd@gnu.org>

12548 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
12550 * lisp.h (eassert): Assume C89 or later.
12551 This removes the need for CHECK.
12552 (CHECK): Remove. Its comments about always evaluating its
12553 argument were confusing, as 'eassert' typically does not evaluate
12556 * coding.c (produce_chars): Use ptrdiff_t, not int.
12558 * xterm.c (x_draw_underwave): Check for integer overflow.
12559 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
12561 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
12563 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
12564 referenced (Bug#11583).

12657 indexing into it->string_overlays array. (Bug#11653)
12658 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

12733 * alloc.c (make_number) [!defined make_number]:
12734 Remove, as lisp.h always defines this now.

12744 code works fine either way, and efficiency is not a concern here,
12745 as the union type is for debugging, not for production.
12746 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12747 Use an inline function on all platforms when using the union type,
12748 since this is simpler and 'static inline' can be used portably
12750 (LISP_INITIALLY_ZERO): New macro.
12751 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12752 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12855 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12857 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12859 * alloc.c (allocate_vectorlike): Fix last change.

12892 * doprnt.c (doprnt): Truncate multibyte char correctly.
12893 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12894 would mishandle a string argument "Xc" if X was a multibyte
12895 character of length 2: it would truncate after X's first byte
12896 rather than including all of X.
12898 2012-06-06 Chong Yidong <cyd@gnu.org>
12900 * buffer.c (word_wrap): Doc fix.

12947 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12949 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12950 Convert pctcpu and pctmem to Lisp float properly.
12951 Let the compiler fold better, as 100.0/0x8000 is exact.
12953 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12955 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

12962 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12964 For a 'struct window', replace some Lisp_Object fields to
12965 bitfields where appropriate, remove unused fields.
12966 * window.h (struct window): Remove unused 'last_mark_x' and
12967 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12968 change its type from Lisp_Object to bitfield.
12969 Change type of 'force_start', 'optional_new_start',
12970 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12977 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12978 Use 'float' consistently, rather than 'float' in most places
12979 and 'double' in a couple of places.
12981 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12983 * xdisp.c (handle_stop): Detect whether we have overlay strings
12984 loaded by testing it->current.overlay_string_index to be
12985 non-negative, instead of checking whether n_overlay_strings is
12986 positive. (Bug#11587)
12988 2012-05-31 Chong Yidong <cyd@gnu.org>
12990 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12996 * search.c (search_buffer): Remove calls to
12997 r_alloc_inhibit_buffer_relocation, as it is now called by

13003 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13004 for the duration of call to load_charset, to avoid problems with
13005 callers of maybe_unify_char that access buffer text through C
13008 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
13009 decrement the inhibition flag, instead of just setting or
13012 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13014 Remove obsolete '#define static' cruft.
13015 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
13016 This #undef was "temporary" in 2000; it is no longer needed
13017 now that '#define static' has gone away.
13018 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
13019 (gray_bitmap_bits): Remove; no longer needed.

13032 (safe_bcopy): Remove decl; no longer has that name.
13033 (main): Coalesce #if into single bit of code, for simplicity.

13064 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13065 Bug#9642, but explicitly check that the buffer the overlay would
13066 be moved to is live and rearrange lines to make sure that errors
13067 will not put the overlay in an inconsistent state.
13068 (Fdelete_overlay): Cosmetics.
13070 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13072 * w32term.c (my_bring_window_to_top): New function.
13073 (x_raise_frame): Use handle returned by DeferWindowPos, which
13074 could be different from the original one.
13075 Call my_bring_window_to_top instead of my_set_foreground_window.

13084 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
13086 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13087 This avoids undefined behavior that might cause the eassert
13088 to not catch an out-of-range value.
13090 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13092 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13093 Update dependencies.
13095 2012-05-27 Eli Zaretskii <eliz@gnu.org>

13102 when referring to sectname field in printf format.
13104 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13106 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13107 Only r_alloc_inhibit_buffer_relocation needed to be added;
13108 the others were already declared.
13110 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13111 before checking whether it's out of range. Put the check inside
13113 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13115 2012-05-27 Ken Brown <kbrown@cornell.edu>
13117 * callproc.c (Fcall_process): Restore a line that was accidentally
13118 commented out in the 2011-02-13 change (bug#11547).
13120 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13122 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13123 defined on ralloc.c.
13125 * buffer.c [REL_ALLOC]: Remove prototypes of
13126 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13127 they are now on lisp.h.
13129 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13131 * search.c (search_buffer): Use it to inhibit relocation of buffer
13132 text while re_search_2 is doing its job, because re_search_2 is
13133 passed C pointers to buffer text. (Bug#11519)
13135 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13136 Update value to 24.
13138 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13139 state after an additional call to move_it_in_display_line_to, keep
13140 the values of it->max_ascent and it->max_descent found for the
13142 (pos_visible_p): Revert the comparison against bottom_y to what it
13143 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13146 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13148 Fix coding-related core dumps with gcc -ftrapv.
13149 The code was computing A - B, where A and B are pointers, and B is
13150 random garbage. This can lead to core dumps on platforms that
13151 have special pointer registers, and it also leads to core dumps on
13152 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13153 A - B only when B is initialized properly.
13154 * coding.c (coding_set_source, coding_set_destination): Return void.
13155 (coding_change_source, coding_change_destinations): New functions,
13156 with the old behaviors of coding_set_source and coding_set_destination.
13157 All callers that need an offset changed to use these new functions.
13159 2012-05-26 Glenn Morris <rgm@gnu.org>
13161 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13163 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13165 Extend mouse support on W32 text-mode console.
13166 * xdisp.c (draw_row_with_mouse_face):
13167 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13169 * w32console.c: Include window.h.
13170 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13172 (initialize_w32_display): Initialize mouse-highlight data.
13174 * w32inevt.c: Include termchar.h and window.h.
13175 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13176 moves, call note_mouse_highlight. If help_echo changed, call
13177 gen_help_event to produce help-echo message in the echo area.
13178 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13181 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13183 * lread.c (read1): Simplify slightly to avoid an overflow warning
13184 with GCC 4.7.0 on x86-64.
13186 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13188 * bidi.c (bidi_mirror_char): Revert last change: an int is
13189 definitely wide enough here.
13191 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13193 Fix integer width and related bugs (Bug#9874).

13203 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13204 (allocate_pseudovector):
13205 Use int, not EMACS_INT, where int is wide enough.
13206 (inhibit_garbage_collection, Fgarbage_collect):
13207 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13208 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13209 int might not be wide enough.
13210 (bidi_cache_search, bidi_cache_find, bidi_init_it)

13225 (Foverlay_recenter, last_overlay_modification_hooks_used)
13226 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13227 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13228 (validate_region): Omit unnecessary test for b <= e,
13229 since that's guaranteed by the previous test.
13230 (adjust_overlays_for_delete): Avoid pos + length overflow.
13231 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13232 (report_overlay_modification):
13233 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13234 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13235 Omit pointer cast, which isn't needed anyway, and doesn't work
13236 after the EMACS_INT -> ptrdiff_t change.
13237 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13238 * buffer.h: Adjust decls to match defn changes elsewhere.
13239 (struct buffer_text, struct buffer):
13240 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13241 Use EMACS_INT, not int, where int might not be wide enough.
13242 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13243 not int, to avoid needless 32-bit limit on 64-bit hosts.
13244 (exec_byte_code): Use tighter memory-full test, one that checks
13245 for alloca overflow. Don't compute the address of the object just
13246 before an array, as that's not portable. Use EMACS_INT, not
13247 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13248 * callint.c (Fcall_interactively):
13249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13250 * callproc.c (call_process_kill, Fcall_process):
13251 Don't assume pid_t fits into an Emacs fixnum.
13252 (call_process_cleanup, Fcall_process, child_setup):

13260 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13261 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13262 (casify_object): Avoid integer overflow when overallocating buffer.
13263 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13264 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13265 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13266 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13267 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13268 integers are now checked earlier. All uses replaced with XINT.
13270 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13271 For CCL_MapSingle, check that content and value are in int range.
13272 (ccl_driver, Fregister_code_conversion_map):
13273 Check that Vcode_version_map_vector is a vector.
13274 (resolve_symbol_ccl_program): Check that vector header is in range.
13275 Always copy the vector, so that we can check its contents reliably
13276 now rather than having to recheck each instruction as it's being
13277 executed. Check that vector words fit in 'int'.
13278 (ccl_get_compiled_code, Fregister_ccl_program)
13279 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13280 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13281 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13282 contents are in range.
13283 (Fccl_execute_on_string): Check that status is in range.
13284 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13285 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13286 Accept and return EMACS_INT, not int, because callers can pass values
13287 out of 'int' range.

13289 (multibyte_chars_in_text, parse_str_as_multibyte)

13293 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13294 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13295 avoid mishandling large integers.
13296 * character.h: Adjust decls to match defn changes elsewhere.
13297 * charset.c (load_charset_map_from_file, find_charsets_in_text)

13302 Don't assume fixnum fits in int.
13303 (load_charset_map_from_vector, Fmap_charset_chars):
13304 Remove now-unnecessary CHECK_NATNUMs.
13305 (Fdefine_charset_internal): Check ranges here, more carefully.
13306 Don't rely on undefined behavior with signed left shift overflow.
13307 Don't assume unsigned int fits into fixnum, or that fixnum fits
13308 into unsigned int. Don't require max_code to be a valid fixnum;
13309 that's not true for gb10830 4-byte on a 32-bit host. Allow
13310 invalid_code to be a cons, for the same reason. Require code_offset
13311 to be a character. Avoid int overflow if max_char is close
13313 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13314 this is intended anyway and avoids some undefined behavior.
13315 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13316 INDEX_TO_CODE_POINT, as that's what it expects.
13317 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13318 * charset.h (DECODE_CHAR): Return int, not unsigned;
13319 this is what was intended anyway, and it avoids undefined behavior.
13320 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13321 integer-overflow issues.
13322 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13323 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13324 where the argument is EMACS_INT, and this behavior is not intended.
13325 * chartab.c (Fmake_char_table, Fset_char_table_range)
13326 (uniprop_get_decoder, uniprop_get_encoder):
13327 Don't assume fixnum fits in int.
13328 * cmds.c (move_point): New function, that does the gist of
13329 Fforward_char and Fbackward_char, but does so while checking
13330 for integer overflow more accurately.
13331 (Fforward_char, Fbackward_char): Use it.
13332 (Fforward_line, Fend_of_line, internal_self_insert)
13333 (internal_self_insert):
13334 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13393 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
13394 Do not attempt to compute the address of the object just before a

14135 fringe bitmap, synchronize the bidi iterator with the main display
14136 iterator, by calling iterate_out_of_display_property.
14137 (iterate_out_of_display_property): Detect buffer iteration by
14138 testing that it->string is a Lisp string.
14139 (get_next_display_element): When the current object is exhausted,
14140 and there's something on it->stack, call set_iterator_to_next to
14141 proceed with what's on the stack, instead of returning zero.
14142 (set_iterator_to_next): If called at the end of a Lisp string,
14143 proceed to consider_string_end without incrementing string
14144 position. Don't increment display vector index past the end of
14145 the display vector. (Bug#11417)
14146 (pos_visible_p): Don't report a position visible when move_it_to
14147 stopped at the last line of window, which happens to be scanned
14148 backwards by the bidi iteration. (Bug#11464)
14150 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14152 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14153 and right-margin display specs even if the spec is invalid or we
14154 are on a TTY, and thus unable to display on the fringes.
14155 That's because the text with the property will not be displayed anyway,
14156 so we need to signal to the caller that this is a "replacing"
14157 display spec. This fixes display when the spec is invalid or we
14160 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14162 * unexaix.c (make_hdr): Fix typo in prototype.
14163 This bug broke the build on AIX. Problem reported by Gilles Pion.
14165 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14167 * keyboard.c (kbd_buffer_get_event): Read special events also in
14168 batch mode. (Bug#11415)
14170 2012-05-12 Glenn Morris <rgm@gnu.org>
14172 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14174 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14176 * lisp.mk (lisp): Add newcomment.elc.
14178 2012-05-12 Glenn Morris <rgm@gnu.org>
14180 * Makefile.in (MKDIR_P): New, set by configure.
14181 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14183 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14185 Remove unused function hourglass_started.
14186 * dispextern.h (hourglass_started):
14187 * w32fns.c (hourglass_started):
14188 * xdisp.c (hourglass_started): Remove.
14190 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14192 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14193 Update dependencies.
14195 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14197 * xgselect.c (xg_select): Put maxfds+1 into a var.
14198 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14200 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14202 2012-05-10 Dave Abrahams <dave@boostpro.com>
14204 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14205 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14207 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14209 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14210 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14211 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14212 Initialize xd_registered_buses.
14214 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14216 Untag more efficiently if USE_LSB_TAG.
14217 This is based on a proposal by YAMAMOTO Mitsuharu in
14218 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14219 For an admittedly artificial (nth 8000 longlist) benchmark on
14220 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14221 Emacs's overall text size by 1%.
14222 * lisp.h (XUNTAG): New macro.
14223 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14224 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14225 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14226 * eval.c (Fautoload):
14227 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14228 * frame.h (XFRAME): Use XUNTAG.
14230 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14231 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14232 Remove unportable assumptions about print widths of types like
14234 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14235 intptr_t when converting between pointer and integer, to avoid GCC
14236 warnings about wrong width.
14238 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14240 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14241 stack for each reader_thread, instead of defaulting to 8MB
14242 determined by the linker. This avoids failures in creating
14243 subprocesses on Windows 7, see the discussion in this thread:
14244 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14246 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14248 Fix up display of the *Minibuf-0* buffer in the mini window.
14249 * keyboard.c (read_char): Don't clear the echo area if there's no
14251 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14252 contents of *Minibuf-0*) if there's no message displayed in its stead.
14254 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14256 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14259 2012-05-06 Chong Yidong <cyd@gnu.org>
14261 * lisp.mk (lisp): Update.
14263 2012-05-05 Jim Meyering <meyering@redhat.com>
14265 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14267 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14269 * data.c (PUT_ERROR): New macro.
14270 (syms_of_data): Use it. Add new error type `user-error'.
14271 * undo.c (user_error): New function.
14272 (Fprimitive_undo): Use it.
14273 * print.c (print_error_message): Adjust print style for `user-error'.
14274 * keyboard.c (user_error): New function.
14275 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14277 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14279 Do not limit current-time-string to years 1000..9999.
14280 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14281 (Fcurrent_time_string): Support any year that is supported by the
14282 underlying localtime representation. Don't use asctime, as it
14283 has undefined behavior for years outside the range -999..9999.
14285 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14287 Fix race conditions involving setenv, gmtime, localtime, asctime.
14288 Without this fix, interrupts could mess up code that uses these
14289 nonreentrant functions, since setting TZ invalidates existing
14290 tm_zone or tzname values, and since most of these functions return
14291 pointers to static storage.
14292 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14293 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14294 Grow the critical sections to include not just invoking
14295 localtime/gmtime, but also accessing these functions' results
14296 including their tm_zone values if any, and any related TZ setting.
14297 (format_time_string): Last arg is now struct tm *, not struct tm **,
14298 so that the struct tm is saved in the critical section.
14299 All callers changed. Simplify allocation of initial buffer, partly
14300 motivated by the fact that memory allocation needs to be outside
14301 the critical section.
14303 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14305 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14306 with RESET_INTERVAL.
14308 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14309 Remove duplicated buffer name initialization.
14311 2012-05-02 Jim Meyering <jim@meyering.net>
14313 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14315 * xfns.c (x_window): Use xstrdup (Bug#11375).
14317 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14319 * xdisp.c (pos_visible_p): If already at a newline from the
14320 display string before the 'while' loop, don't walk back the glyphs
14321 from it3.glyph_row. Solves assertion violation when the display
14322 string begins with a newline (egg.el). (Bug#11367)
14324 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14326 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14329 2012-05-01 Glenn Morris <rgm@gnu.org>
14331 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14332 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14333 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14334 All were removed before 23.1.
14336 * dispnew.c: Remove HAVE_LIBNCURSES test;
14337 it is always true on relevant platforms.
14339 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14340 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14342 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14344 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14346 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14347 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14350 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14352 Do not avoid creating empty evaporating overlays (Bug#9642).
14353 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14354 That is, do not delete an evaporating overlay if it becomes
14355 empty after its bounds are adjusted to fit within its buffer.
14356 This fix caused other problems, and I'm reverting it until we get
14357 to the bottom of them.
14359 2012-04-27 Chong Yidong <cyd@gnu.org>
14361 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14363 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14365 * xdisp.c (pos_visible_p): If the window start position is beyond
14366 ZV, start the display from buffer beginning. Prevents assertion
14367 violation in init_iterator when the minibuffer window is scrolled
14368 via the scroll bar.
14370 * window.c (window_scroll_pixel_based): Likewise.
14372 2012-04-27 Chong Yidong <cyd@gnu.org>
14374 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14376 2012-04-27 Glenn Morris <rgm@gnu.org>
14378 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14379 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14381 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14383 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14384 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14386 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14388 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14389 display element, check also the underlying string or buffer
14390 character. (Bug#11341)
14392 * w32menu.c: Include w32heap.h.
14393 (add_menu_item): If the call to AppendMenuW (via
14394 unicode_append_menu) fails, disable Unicode menus only if we are
14395 running on Windows 9X/Me.
14397 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14399 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14400 (xgetint): Add missing shift for LSB tags.
14402 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14404 * keyboard.c (read_char): Don't wipe echo area for select window
14405 events: These might get delayed via `mouse-autoselect-window'
14408 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14410 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14411 manipulation of :loaded-from data.
14413 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14415 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14416 now a cons (bug#11311).
14418 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14420 Do not create empty overlays with the evaporate property (Bug#9642).
14421 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14422 if it becomes empty after its bounds are adjusted to fit within
14423 its buffer. Without this fix, in a nonempty buffer (let ((o
14424 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14425 yields an empty overlay that has the evaporate property, which is
14426 not supposed to happen.
14428 Fix minor GTK3 problems found by static checking.
14429 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14430 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14431 (struct _EmacsFixedClass, emacs_fixed_get_type):
14432 Move decls here from emacsgtkfixed.h, since they needn't be public.
14433 (emacs_fixed_get_type): Now static.
14434 (emacs_fixed_class_init): Omit unused local.
14435 (emacs_fixed_child_type): Remove; unused.
14436 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14437 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14438 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14439 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14440 (EMACS_FIXED_GET_CLASS): Remove; unused.
14441 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14443 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14444 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14446 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14448 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14449 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14450 (__malloc_size_t, __malloc_ptrdiff_t):
14451 Remove. All uses removed, replaced by the definiens if needed,
14452 since we can assume C89 or better now.
14453 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

14460 (special_realloc, _realloc_internal_nolock, _realloc_internal)
14461 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14462 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14463 Define using prototypes, not old style.
14464 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14465 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14466 (align): Don't assume that signed integer overflow wraps around.
14467 Omit unused local var.
14468 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

14470 Omit no-longer-needed casts.
14471 (valloc): Use getpagesize, not __getpagesize.
14472 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14473 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14475 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14477 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14479 Move functions from C to Lisp. Make non-blocking method calls
14480 the default. Implement further D-Bus standard interfaces.
14482 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

14524 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
14525 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
14526 Do not assume ptrdiff_t is the same width as 'int'.
14528 * alloc.c: Handle unusual debugging option combinations.
14529 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14530 since the two debugging options are incompatible.
14531 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14533 (mem_init, mem_insert, mem_insert_fixup):
14534 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
14535 (NEED_MEM_INSERT): Remove; no longer needed.
14537 2012-04-22 Leo Liu <sdl.web@gmail.com>

14541 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14543 * sysdep.c [__FreeBSD__]: Minor cleanups.
14544 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14545 Use Emacs indenting style more consistently. Avoid some casts.
14546 Use 'double' consistently rather than mixing 'float' and 'double'.
14548 2012-04-21 Eduard Wiebe <usenet@pusto.de>
14550 * sysdep.c (list_system_processes, system_process_attributes):
14551 Add implementation for FreeBSD (Bug#5243).

14560 It is never used otherwise.
14562 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
14564 * print.c (print_preprocess): Only check print_depth if print-circle
14566 (print_object): Check for cycles even when print-circle is nil and

14569 2012-04-20 Chong Yidong <cyd@gnu.org>
14571 * process.c (wait_reading_process_output): If EIO occurs on a pty,
14572 set the status to "failed" and ensure that sentinel is run.
14574 2012-04-20 Glenn Morris <rgm@gnu.org>
14576 * process.c (Fset_process_inherit_coding_system_flag)
14577 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

14585 row, return zero immediately.
14586 (try_cursor_movement): If inside continuation line, don't back up
14587 farther than the first row after the header line, if any.
14588 Don't consider the header-line row as "partially visible", even if
14589 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14591 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14600 * Makefile.in (C_WARNINGS_SWITCH): Remove.
14601 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
14602 (ALL_CFLAGS): Use new macros rather than old.
14603 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
14604 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
14605 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
14606 -Wunused-result, -Wunused-variable. This should go away once
14607 the Emacs and Gnulib regex code is merged.
14608 (xmalloc, xrealloc): Now static.
14610 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

14627 New extern decls, to avoid calling undeclared functions.
14628 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14629 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14630 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14631 (NEED_MEM_INSERT): New macro.
14632 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14633 Remove one incorrect comment and fix another.

14647 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14648 Remove decls. This fixes an "It stinks!".
14650 * alloc.c (which_symbols): Fix alignment issue / type clash.
14652 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14654 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14655 (struct Lisp_Misc_Any): Likewise.
14656 (struct Lisp_Free): Likewise.
14657 * alloc.c (union aligned_Lisp_Symbol): Define.

14667 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14668 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14669 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14670 * s/netbsd.h, s/sol2-6.h:
14671 Remove definition of GC_MARK_STACK, since the default now works.
14672 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14673 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14674 no longer the default.
14675 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14677 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14679 * lread.c (lisp_file_lexically_bound_p):
14680 Fix hang at ";-*-\n" (bug#11238).
14682 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14684 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14685 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

14694 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
14696 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14698 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14700 2012-04-11 Daniel Colascione <dancol@dancol.org>
14702 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14703 against is gone. It's better to use vfork now so that when Cygwin
14704 gains a new, working vfork, we use it automatically (bug#10398).
14706 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14708 * window.c (save_window_save): Obey window-point-insertion-type.

14724 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14726 * w32.c (w32_delayed_load): Record the full path of the library
14727 being loaded (bug#10424).
14729 2012-04-09 Glenn Morris <rgm@gnu.org>
14731 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14732 not just in the obarray, before snarfing them. (Bug#11036)

14735 Pass EMACS rather than BUILT_EMACS.
14737 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14739 * process.c (make_process):
14740 * process.h: Add integer `gnutls_handshakes_tried' member to

14747 (emacs_gnutls_read): Use new log functions,
14748 `gnutls_handshakes_tried' process member, and
14749 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14750 attempts per process (connection).
14752 2012-04-09 Chong Yidong <cyd@gnu.org>
14754 * eval.c (Fuser_variable_p, user_variable_p_eh)
14755 (lisp_indirect_variable): Functions deleted.
14756 (Fdefvar): Caller changed.
14758 * callint.c (Finteractive, Fcall_interactively):
14759 * minibuf.c (Fread_variable): Callers changed.
14761 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14763 * xdisp.c (set_cursor_from_row): If the display string appears in
14764 the buffer at position that is closer to point than the position
14765 after the display string, display the cursor on the first glyph of
14766 the display string. Fixes cursor display when a 'display' text
14767 property immediately follows invisible text. (Bug#11094)
14769 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14771 composite.c: use 'double' consistently
14772 * composite.c (get_composition_id): Use 'double' consistently
14773 instead of converting 'float' to 'double' and vice versa; this is
14774 easier to understand and avoids a GCC warning.
14776 2012-04-09 Glenn Morris <rgm@gnu.org>
14778 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14779 preparation for dumping it with emacs. (Bug#4789)
14780 (leimdir): New variable.

14800 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14801 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14802 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14803 objects, as mark_maybe_pointer will catch them otherwise.
14804 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14805 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

14812 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14814 Support building on MS-Windows with libxml2.
14816 * makefile.w32-in (OBJ2): Add xml.$(O).
14817 (GLOBAL_SOURCES): Add xml.c.
14818 ($(BLD)/xml.$(O)): New dependency list.
14820 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14821 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14822 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14823 [!WINDOWSNT]: New macros.
14824 (init_libxml2_functions, libxml2_loaded_p): New functions.
14825 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14826 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14827 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14828 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14830 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14831 Call init_libxml2_functions before calling libxml2 functions.
14832 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14834 * emacs.c: Don't include libxml/parser.h.
14835 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14836 xmlCleanupParser directly.
14838 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14840 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14842 * indent.c (Fvertical_motion): If there is a display string at
14843 point, use it.vpos to compute how many lines to backtrack after
14844 move_it_to point. (Bug#11133)
14846 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14848 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14849 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14850 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14851 macros related to unification of CJK characters. For the details,
14852 see the discussion following the message here:
14853 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14855 2012-04-04 Chong Yidong <cyd@gnu.org>
14857 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14859 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14861 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14862 instead of alloca. (Bug#11138)
14864 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14866 * w32menu.c (is_simple_dialog): Properly check lisp types.
14869 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14871 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14872 position we get to after a call to move_it_to fails the
14873 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14874 only if we wind up in a string from display property. (Bug#11063)
14876 * window.c (Fdelete_other_windows_internal): Invalidate the row
14877 and column information about mouse highlight, so that redisplay
14878 restores it after reallocating the glyph matrices. (Bug#7464)
14880 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14881 string comes from a `display' text property, use the buffer
14882 position of that property as if we actually saw that position in
14884 (move_it_by_lines): Remove the assertion that
14885 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14886 violated when there's a before-string at the beginning of a line.
14889 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14891 * xdisp.c (append_space_for_newline): If the default face was
14892 remapped, use the remapped face for the appended newline.
14893 (extend_face_to_end_of_line): Use the remapped default face for
14894 extending the face to the end of the line.
14895 (display_line): Call extend_face_to_end_of_line when the default
14896 face was remapped. (Bug#11068)
14898 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14900 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14902 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

14918 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14919 (command_loop_1): Use it; inhibit selection update for
14920 handle-select-window too (Bug#8996).

14924 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14926 2012-03-25 Kenichi Handa <handa@m17n.org>
14928 * dispextern.h (struct glyph): Change the bit length of
14929 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14931 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14933 * s/ms-w32.h (tzname): Include time.h before redirecting to

14938 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14941 * xterm.c (XTread_socket): Only modify handling_signal if
14942 !SYNC_INPUT. (Bug#11080)
14944 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14946 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14947 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14948 when fetching a multibyte character consumes more bytes than
14949 CHAR_BYTES returns, due to unification of CJK characters in
14950 string_char. (Bug#11073)
14952 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14954 * process.c (wait_reading_process_output): Handle pty disconnect
14955 by refraining from sending oneself a SIGCHLD (bug#10933).
14957 2012-03-22 Chong Yidong <cyd@gnu.org>
14959 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14961 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14962 Mark string as coming from a prefix property.
14963 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14964 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14966 2012-03-21 Chong Yidong <cyd@gnu.org>
14968 * xfaces.c (Vface_remapping_alist): Doc fix.
14970 2012-03-20 Eli Zaretskii <eliz@gnu.org>

14984 it fit in a valid range (Bug#11003).
14986 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14988 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14989 that is not from display property, accept the row as a "cursor
14990 row" if one of the string's character has a non-nil `cursor'
14991 property. Fixes cursor positioning when there are newlines in
14992 overlay strings, e.g. in icomplete.el. (Bug#11035)
14994 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14996 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14998 2012-03-12 Chong Yidong <cyd@gnu.org>
15000 * eval.c (inhibit_lisp_code): Rename from
15001 inhibit_window_configuration_change_hook; move from window.c.
15003 * xfns.c (unwind_create_frame_1, Fx_create_frame):
15004 * window.c (run_window_configuration_change_hook)
15005 (syms_of_window): Callers changed.
15007 2012-03-11 Chong Yidong <cyd@gnu.org>
15009 * keymap.c (Fkey_description): Doc fix (Bug#9700).
15011 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
15013 2012-03-10 Chong Yidong <cyd@gnu.org>
15015 * frame.c (other_visible_frames): Don't assume the selected frame
15016 is visible (Bug#10955).
15018 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
15020 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
15022 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
15024 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
15025 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15028 2012-03-03 Glenn Morris <rgm@gnu.org>
15030 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15032 2012-03-02 Eli Zaretskii <eliz@gnu.org>
15034 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
15035 position past the first glyph_row that ends at ZV. (Bug#10902)
15036 (redisplay_window, next_element_from_string): Fix typos in
15038 (redisplay_window): Pass to move_it_vertically the margin in
15039 pixels, not in screen lines.
15041 2012-03-02 Glenn Morris <rgm@gnu.org>
15043 * buffer.c (buffer-list-update-hook): Doc fix.
15045 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15047 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15048 push_it before setting up the iterator for the first overlay
15049 string, even if we have an empty string loaded.
15050 (next_overlay_string): If there's an empty string on the iterator
15051 stack, pop the stack. (Bug#10903)
15053 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15055 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15056 Suggested by Stefan Monnier in
15057 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15058 * alloc.c (widen_to_Lisp_Object): New static function.
15059 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15060 and widening them to Lisp_Objects. This would work even if
15061 USE_LSB_TAG is defined and wide integers are used, which might
15062 happen in a future version of Emacs.
15064 2012-02-25 Chong Yidong <cyd@gnu.org>
15066 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

15071 before saving to clipboard manager.
15073 2012-02-24 Chong Yidong <cyd@gnu.org>
15075 * keyboard.c (process_special_events): Handle all X selection
15076 requests in kbd_buffer, not just the next one (Bug#8869).
15078 2012-02-23 Chong Yidong <cyd@gnu.org>
15080 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15081 call when setting menu-bar-lines and tool-bar-lines parameters.
15082 (unwind_create_frame_1): New helper function.
15084 * window.c (inhibit_window_configuration_change_hook): New var.
15085 (run_window_configuration_change_hook): Obey it.
15086 (syms_of_window): Initialize it.
15088 2012-02-22 Chong Yidong <cyd@gnu.org>

15103 when computing $valmask.
15105 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15106 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15107 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15108 It's useless in that case, and it can cause problems on hosts
15109 that allocate halves of EMACS_INT values separately.
15110 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15111 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15112 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15113 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15114 it avoids undefined behavior on hosts where shifting right by more
15115 than the word width has undefined behavior.
15117 2012-02-19 Chong Yidong <cyd@gnu.org>
15119 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15120 (Funhandled_file_name_directory, Ffile_name_as_directory)
15121 (Fdirectory_file_name, Fexpand_file_name)
15122 (Fsubstitute_in_file_name): Protect against invalid file handler
15123 return values (Bug#10845).
15125 2012-02-18 Eli Zaretskii <eliz@gnu.org>

15137 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
15139 2012-02-15 Chong Yidong <cyd@gnu.org>
15141 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
15142 marked as special. Also, starting docstrings with * is obsolete.

15157 2012-02-12 Chong Yidong <cyd@gnu.org>
15159 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15160 as that creates a dangerous corner case.
15162 * window.c (Fdelete_window_internal): Invalidate the mouse
15163 highlight (Bug#9904).
15165 2012-02-12 Glenn Morris <rgm@gnu.org>

15172 (Fx_selection_owner_p, Fx_get_selection_internal):
15173 Sync docs and argument specs with the xselect.c versions.
15175 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

15195 2012-02-07 Chong Yidong <cyd@gnu.org>
15197 * buffer.c (Fbuffer_local_variables)
15198 (buffer_lisp_local_variables): Handle unbound vars correctly;
15199 don't let Qunbound leak into Lisp.
15201 2012-02-07 Glenn Morris <rgm@gnu.org>
15203 * image.c (Fimagemagick_types): Doc fix.
15205 * image.c (imagemagick-render-type): Change it from a lisp object
15206 to an integer. Move the doc here from the lisp manual.

15223 2012-02-04 Eli Zaretskii <eliz@gnu.org>
15225 * w32.c (get_emacs_configuration_options):
15226 Include --enable-checking, if specified, in the return value.

15236 before BEGV. (Bug#10696)
15238 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15240 Handle overflow when computing char display width (Bug#9496).
15241 * character.c (char_width): Return EMACS_INT, not int.
15242 (char_width, c_string_width): Check for overflow when
15243 computing the width; this is possible now that individual
15244 characters can have unbounded width. Problem introduced
15245 by merge from Emacs 23 on 2012-01-19.

15265 0, do not call append_composite_glyph.
15267 2012-02-02 Kenichi Handa <handa@m17n.org>
15269 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
15271 (x_produce_glyphs): If the component of a composition is a null

15276 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15277 first 2 arguments are identical. This makes inserting large
15278 output from a subprocess an order of magnitude faster on
15279 MS-Windows, where all sbrk'ed memory is always contiguous.
15281 2012-01-31 Glenn Morris <rgm@gnu.org>

15379 DISP_STRING, and accept any glyph in a row whose object is that
15380 string as eligible for mouse highlight. Fixes mouse highlight of
15381 display strings from overlays. (Bug#10464)
15383 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>

15917 behave as if the cursor position were at the window margin.
15919 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15920 and the cursor position is out of bounds, behave as if the cursor
15921 position were at the window margin. (Bug#10075)
15923 2011-11-18 Chong Yidong <cyd@gnu.org>

15947 compute_line_metrics.
15948 (compute_line_metrics): Call row_hash, instead of computing the
15951 * dispnew.c (verify_row_hash): Call row_hash for computing the
15952 hash code of a row, instead of duplicating code from xdisp.c.
15954 * dispextern.h (row_hash): Add prototype.
15956 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

16141 Otherwise, these inline functions do not conform to C99 and
16142 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16143 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16144 * intervals.c (adjust_intervals_for_insertion)

16434 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16436 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16438 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16440 * keyboard.c (test_undefined): New function (bug#9751).
16441 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16443 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16445 * sysdep.c (init_sys_modes): Fix the check for the controlling
16446 terminal (Bug#6649).
16448 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16450 * dispextern.h (struct bidi_it): New member next_en_type.
16452 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16453 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16454 current character, check also for next_en_type being WEAK_EN.
16455 (bidi_resolve_weak): Don't enter the expensive loop if the current
16456 position is before next_en_pos. Record the bidi type of the first
16457 non-ET, non-BN character we find, in addition to its position.
16458 (bidi_level_of_next_char): Invalidate next_en_type when
16459 next_en_pos is over-stepped.
16461 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16463 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16464 * editfns.c: Rewrite current-time-zone so that it invokes
16465 the equivalent of (format-time-string "%Z") to get the time zone name.
16466 This fixes a bug when the time zone name contains characters that
16467 need converting from the system time locale to Emacs internal format.
16468 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16469 that patch fixed format-time-string to do the conversion, but
16470 I forgot to fix current-time-zone.
16471 (format_time_string): New function, containing most of
16472 what Fformat_time_string used to contain.
16473 (Fformat_time_string): Rewrite in terms of format_time_string.
16474 This doesn't change this function's behavior.
16475 (current-time-zone): Rewrite to use format_time_string.
16476 This fixes the bug reported by Michael Schierl in
16477 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16478 Jason Rumney's 2007-06-07 change worked around this bug, but
16480 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16482 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16484 * xdisp.c (start_display): If the character at POS is displayed
16485 via a display vector, reset IT->current.dpvec_index to zero.
16486 (try_window_reusing_current_matrix): If a line ends in a display
16487 vector or the next line starts in a display vector, continue
16488 redrawing the window even though the character position of
16489 start_row was reached.
16492 2011-10-18 Chong Yidong <cyd@gnu.org>
16494 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16495 with nobreak-char-display too.
16497 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16499 Fix part 3 of bug#9771.
16500 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16501 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16502 non-neutral characters if the current character is a paragraph
16503 separator (a.k.a. Newline). This avoids running the same
16504 expensive loop twice, once when we consume the preceding newline
16505 and the other time when the line actually needs to be displayed.
16506 Avoid the loop when we see neutrals on the base embedding level
16507 following a character whose directionality is the same as the
16508 paragraph's. This avoids running the expensive loop when a line
16509 ends in a long sequence of neutrals, like control characters.
16510 Add assertion against STRONG_AL type. Slightly rearrange code
16511 that determines the type of a neutral given the first non-neutral
16513 (bidi_level_of_next_char): Set next_en_pos to zero when
16514 invalidating its info.
16516 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16518 * xdisp.c (push_display_prop): Determine whether to record string
16519 or buffer position by IT->string, not by IT->method. Allow
16520 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16521 (move_it_vertically_backward): Don't look for character position
16522 immediately after the newline when in a continuation line.
16525 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16527 * window.c (coordinates_in_window): Rewrite and delabelize
16528 vertical border check. (Bug#5357) (Bug#9618)
16530 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16532 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16533 errors in XSetWindowBorder (bug#9310).
16535 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16537 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16538 avoid crash when xmalloc overrun checking is enabled.
16540 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16542 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16543 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16544 cursor motion with <left> and <right> arrow keys.
16546 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16547 some callers set that themselves.
16549 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16551 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16552 display string and the previous row comes from the same string and
16553 is empty. (Bug#9739) (Bug#9738)
16555 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16557 * doc.c (get_doc_string): Encode file name (bug#9735).
16559 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16561 * bidi.c (bidi_level_of_next_char):
16562 * xdisp.c (get_visually_first_element): Remove old incorrect
16563 comments regarding the Unicode Line Separator character.
16565 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16567 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16569 * alloc.c (Fgc_status): Do not access beyond zombies array
16570 boundary if nzombies > MAX_ZOMBIES.
16571 * alloc.c (dump_zombies): Add missing format specifier.
16573 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16575 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16576 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16578 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16579 Some packages use them to denote characters with modifiers.
16581 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16583 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16584 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16585 matching a pp-number. Rename parameter var to var1.
16587 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16589 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16591 2011-10-08 Glenn Morris <rgm@gnu.org>
16593 * callint.c (Fcall_interactively): Give a more explicit error for the
16594 'c' case with a non-character input. (Bug#8479)
16596 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16598 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16600 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16601 lines that are hscrolled on the left.
16603 * dispnew.c (buffer_posn_from_coords): Account for a possible
16604 presence of header-line. (Bug#4426)
16606 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16608 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16609 Don't advertise functionality which we discourage or doesn't work.
16611 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16613 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16614 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16615 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16616 this makes Emacs dump core during garbage collection on rare
16617 occasions. sizeof is obviously inferior to offsetof here, so
16618 stick with offsetof.
16619 (GC_POINTER_ALIGNMENT): New macro.
16620 (mark_memory): Omit 3rd (offset) arg; caller changed.
16621 Don't assume EMACS_INT alignment is the same as pointer alignment.
16623 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16625 * keyboard.c (read_key_sequence_remapped): New var.
16626 (read_key_sequence): Compute remapping in the right buffer.
16627 (command_loop_1): Use read_key_sequence's remapping directly.
16629 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16631 * dired.c (file_name_completion): Don't expand file name.
16632 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16633 before checking file name handler.
16635 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16636 they've been requested explicitly (bug#9591).
16638 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16640 * keymap.c (Fsingle_key_description): Use make_specified_string
16641 instead of build_string to build string from push_key_description.
16644 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16646 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16647 This fixes a Y2038 bug on 64-bit hosts.
16648 * buffer.c (reset_buffer):
16649 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16650 (Fclear_buffer_auto_save_failure):
16651 Use 0, not -1, to represent an unset failure time, since time_t
16652 might not be signed.
16654 Remove dependency on glibc malloc internals.
16655 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16656 Move back here from lisp.h, but with their new implementations.
16657 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16658 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16659 * charset.c (charset_table_init): New static var.
16660 (syms_of_charset): Use it instead of xmalloc. This removes a
16661 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16662 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16663 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16664 Move back to alloc.c.
16665 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16666 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16668 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16670 * nsterm.m (windowDidResize): Call x_set_window_size only when
16671 ns_in_resize is true. Otherwise set pixelwidth/height and
16672 call change_frame_size (Bug#9628).
16674 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16676 Port --enable-checking=all to Fedora 14 x86-64.
16677 * charset.c (syms_of_charset): Also account for glibc malloc's
16678 internal overhead when calculating the initial malloc maximum.
16680 Port --enable-checking=all to Fedora 14 x86.
16681 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16683 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16684 (overrun_check_realloc, overrun_check_free):
16685 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16686 That way, xmalloc returns a properly-aligned pointer even if
16687 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16688 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16689 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16690 into account when calculating the initial malloc maximum.
16691 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16692 Move here from alloc.c, so that charset.c can use it too.
16693 Properly align; the old code wasn't right for common 32-bit hosts
16694 when configured with --enable-checking=all.
16695 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16696 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16698 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16700 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16703 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16705 * xdisp.c (compute_display_string_end): If there's no display
16706 string at CHARPOS, return -1.
16708 * bidi.c (bidi_fetch_char): When compute_display_string_end
16709 returns a negative value, treat the character as a normal
16710 character not covered by a display string. (Bug#9624)
16712 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16714 * lread.c (Fread_from_string): Fix typo in docstring.
16716 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16718 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16719 newline, reseat the iterator instead of bidi-iterating there one
16720 character at a time. (Bug#9610)
16721 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16722 TO_CHARPOS if the bidi iterator is at base embedding level.
16724 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16726 * lread.c (readevalloop): Use correct code for NBSP.
16727 (read1): Likewise. (Bug#9608)
16729 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16731 * dbusbind.c (Fdbus_register_signal): When service is not
16732 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16734 2011-09-25 Glenn Morris <rgm@gnu.org>
16736 * buffer.c (truncate-lines): Doc fix.
16738 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16740 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16741 (Fset_window_next_buffers): Doc fix.
16743 2011-09-24 Glenn Morris <rgm@gnu.org>
16745 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16747 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16749 Fix minor problems found by static checking.
16750 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16751 * indent.c (Fvertical_motion): Fix == vs = typo.
16753 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16755 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16756 Default value is now t. Doc fix.
16758 * indent.c (Fvertical_motion): Compute and apply the overshoot
16759 logic when moving up, not only when moving down. Fix the
16760 confusing name and values of the it_overshoot_expected variable;
16761 logic changes accordingly. (Bug#9254) (Bug#9549)
16763 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16764 CHARPOS is covered by a display string which includes newlines.
16765 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16766 is covered by a display string with embedded newlines.
16768 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16770 * dbusbind.c (Fdbus_register_signal): Add match rule to
16771 Vdbus_registered_objects_table. (Bug#9581)
16772 (Fdbus_register_method, Vdbus_registered_objects_table):
16775 2011-09-24 Jim Meyering <meyering@redhat.com>
16777 do not ignore write error for any output size
16778 The previous change was incomplete.
16779 While it makes emacs --batch detect the vast majority of stdout
16780 write failures, errors were still ignored whenever the output size is
16781 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16782 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16783 && echo FAIL: ignored write error
16784 FAIL: ignored write error
16785 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16786 && echo FAIL: ignored write error
16787 FAIL: ignored write error
16788 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16790 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16792 * emacs.c (Fkill_emacs): In noninteractive mode exit
16793 non-successfully if a write error occurred on stdout. (Bug#9574)
16795 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16797 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16800 * dispextern.h (struct it): Update the comment documenting what
16803 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16805 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16806 a display string, extend search for cursor position to end of row.
16807 (find_row_edges): If the row ends in a newline from a display
16808 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16809 Handle the case of a display string with multiple newlines.
16810 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16811 non-empty line. Fixes confusing cursor motion with arrow keys at
16812 the beginning of a line that starts with whitespace.
16814 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16816 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16819 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16821 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16822 boolean (Bug#9154).
16824 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16826 * xdisp.c (display_line): Record maximum and minimum buffer
16827 positions even if no glyphs were produced (e.g., by a zero-width
16828 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16829 buffer positions that will be removed from the glyph row because
16831 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16832 column is beyond frame width: don't subtract 1 "pixel" when
16833 computing width of the stretch.
16834 (reseat_at_next_visible_line_start): Undo the change made on
16835 2011-09-17 that saved paragraph information and restored it after
16836 the call to `reseat'. (Bug#9545)
16838 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16840 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16841 and turn window cursor on if cleared (Bug#9415).
16843 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16845 * search.c (boyer_moore): Take unibyte characters from pattern
16846 literally. (Bug#9458)
16848 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16850 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16852 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16854 Fix minor problem found by static checking.
16855 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16856 initialized, to pacify gcc -Wuninitialized.
16858 * fileio.c: Report proper errno when syscall falls.
16859 (Finsert_file_contents): Save and restore errno,
16860 so that report_file_error outputs the correct diagnostic.
16861 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16863 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16865 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16867 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16869 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16870 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16872 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16874 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16875 about the current paragraph and restore it after the call to reseat.
16877 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16878 (bidi_find_paragraph_start): Search back for paragraph beginning
16879 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16880 (bidi_move_to_visually_next): Only trigger paragraph-related
16881 computations when the last character is a newline or at EOB, not
16882 just any NEUTRAL_B. (Bug#9470)
16884 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16885 truncated lines if point is covered by a display string. (Bug#9524)
16887 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16889 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16890 (cons_to_x_long): New function.
16891 (lisp_data_to_selection_data): Use it. Correct the test for
16892 short-versus-long data; it was negated. Break out of vector
16893 loop, for efficiency, when a long datum is discovered.
16895 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16897 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16899 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16901 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16902 GCC PR/17406) by declaring this function with external scope.
16904 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16906 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16907 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16909 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16911 * editfns.c (Fformat): Correctly handle text properties on "%%".
16913 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16915 * xterm.c (x_draw_composite_glyph_string_foreground):
16916 * w32term.c (x_draw_composite_glyph_string_foreground):
16917 * term.c (encode_terminal_code):
16918 * composite.c (composition_update_it, get_composition_id):
16919 * xdisp.c (get_next_display_element)
16920 (fill_composite_glyph_string): Add comments about special meaning
16921 of TAB characters in a composition.
16923 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16925 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16926 This occurs when processing a multibyte format.
16927 Problem reported by Wolfgang Jenker.
16929 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16931 * xdisp.c (try_cursor_movement): Only check for exact match if
16932 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16934 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16936 Remove unused external symbols.
16937 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16938 * xdisp.c (calc_pixel_width_or_height): Now static.
16939 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16940 * indent.c (check_display_width):
16941 * w32term.c: Fix comment to match code.
16942 * xterm.c, xterm.h (x_catching_errors): Remove.
16944 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16946 * xselect.c: Use signed conversions more consistently (Bug#9498).
16947 (selection_data_to_lisp_data): Assume incoming selection data are
16948 signed integers, not unsigned. This is to be consistent with
16949 outgoing selection data, which was modified to use signed integers
16950 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16951 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16952 expects long, not unsigned long.
16954 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16956 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16957 computation of loop end. Reported by Johan Bockgård
16960 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16962 * frame.c (Fother_visible_frames_p): Function deleted.
16964 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16966 * indent.c (compute_motion): Process display vector front to back
16967 rather than the other way around. (Bug#2496)
16969 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16971 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16973 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16975 * minibuf.c (Fread_from_minibuffer): Doc fix.
16977 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16979 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16980 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16982 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16984 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16985 value for non-existent files.
16987 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16989 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16990 set its "size" to -1. This will set the modtime_size field of
16991 the corresponding buffer to -1, which is what
16992 verify-visited-file-modtime expects for files that do not exist.
16995 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16997 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16999 * lisp.h: ... from here. push_key_description is no longer
17000 defined in keyboard.c, so its declaration should not be in
17001 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17002 logically belongs with push_key_description.
17004 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
17006 * buffer.h: Include <sys/types.h> instead of <time.h>.
17007 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
17008 Problem reported by Herbert J. Skuhra.
17010 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
17012 * xml.c (parse_region): Make the parsing work for
17013 non-comment-starting XML files again (bug#9144).
17015 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17017 * image.c (gif_load): Fix calculation of bottom and right corner.
17020 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17022 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17023 redisplay in small windows.
17025 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17027 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17029 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17031 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17032 Operate on live windows only.
17034 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17036 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17038 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17040 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17041 only under bidi iteration.
17043 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17045 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17047 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17049 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17050 Without this fix, the command to link temacs failed due to an
17051 undefined symbol __builtin_isnan. This is because
17052 /usr/include/iso/math_c99.h #defines isnan(x) to
17053 __builtin_isnan(x), but the bundled gcc, which identifies itself
17054 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17056 * floatfns.c (isnan): #undef, and then #define to a clone of
17058 (Fisnan): Always define, since it's always available now.
17059 (syms_of_floatfns): Always define isnan at the Lisp level.
17061 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17063 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17065 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17067 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17068 The previous code assumed that file offsets (off_t values) fit in
17069 EMACS_INT variables, which is not true on typical 32-bit hosts.
17070 The code messed up by falsely reporting buffer overflow in cases
17071 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17072 when "big" contains more than 2**29 bytes, even though this
17073 inserts just one byte and does not overflow the buffer.
17074 (Finsert_file_contents): Store file offsets as off_t
17075 values, not as EMACS_INT values. Check for overflow when
17076 converting between EMACS_INT and off_t. When checking for
17077 buffer overflow or for overlap, take the offsets into account.
17078 Don't use EMACS_INT for small values where int suffices.
17079 When checking for overlap, fix a typo: ZV was used where
17080 ZV_BYTE was intended.
17081 (Fwrite_region): Don't assume off_t fits into 'long'.
17082 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17084 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17086 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17088 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17090 sprintf-related integer and memory overflow issues (Bug#9412).
17092 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17093 (esprintf, exprintf, evxprintf): New functions.
17094 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17095 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17096 (modify_event_symbol): Do not assume that the length of
17097 name_alist_or_stem is safe to alloca and fits in int.
17098 (Fexecute_extended_command): Likewise for function name and binding.
17099 (Frecursion_depth): Wrap around reliably on integer overflow.
17100 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17101 since some callers pass EMACS_INT values.
17102 (Fsingle_key_description): Don't crash if symbol name contains more
17103 than MAX_ALLOCA bytes.
17104 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17105 (get_minibuffer): Arg is now EMACS_INT, not int.
17106 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17107 (esprintf, exprintf, evxprintf): New decls.
17108 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17110 * dbusbind.c (signature_cat): New function.
17111 (xd_signature, Fdbus_register_signal):
17112 Do not overrun buffer; instead, report string overflow.
17114 * dispnew.c (add_window_display_history): Don't overrun buffer.
17115 Truncate instead; this is OK since it's just a log.
17117 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17118 even if the time zone offset is outlandishly large.
17119 Don't mishandle offset == INT_MIN.
17121 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17122 when creating daemon; the previous buffer-overflow check was incorrect.
17124 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17125 which has the guts of the old verror function.
17127 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17128 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17130 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17131 (font_unparse_xlfd): Don't blindly alloca long strings.
17132 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17133 fits in int, when using sprintf. Use single snprintf to count
17134 length of string rather than counting it via multiple sprintfs;
17135 that's simpler and more reliable.
17136 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17137 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17138 sprintf, in case result does not fit in int.
17140 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17141 (fontset_from_font): Print it.
17143 * frame.c (tty_frame_count): Now printmax_t, not int.
17144 (make_terminal_frame, set_term_frame_name): Print it.
17145 (x_report_frame_params): In X, window IDs are unsigned long,
17146 not signed long, so print them as unsigned.
17147 (validate_x_resource_name): Check for implausibly long names,
17148 and don't assume name length fits in 'int'.
17149 (x_get_resource_string): Don't blindly alloca invocation name;
17150 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17153 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17154 (xg_check_special_colors, xg_set_geometry):
17155 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17157 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17158 Use esprintf, not sprintf, in case result does not fit in int.
17160 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17161 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17162 it as a large positive number.
17163 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17164 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17166 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17167 in case result does not fit in int.
17169 * print.c (float_to_string): Detect width overflow more reliably.
17170 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17171 buffer overrun. Don't assume list length fits in 'int'. Treat
17172 print length of 0 as 0, not as infinity; to be consistent with other
17173 uses of print length in this function. Don't overflow print length
17174 index. Don't assume hash table size fits in 'long', or that
17175 vectorlike size fits in 'unsigned long'.
17177 * process.c (make_process): Use printmax_t, not int, to format
17178 process-name gensyms.
17180 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17182 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17183 to avoid potential buffer overrun.
17185 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17186 if X resource line is longer than 512 bytes.
17188 * xfns.c (x_window): Make sprintf buffer a bit bigger
17189 to avoid potential buffer overrun.
17191 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17193 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17195 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17197 Integer overflow fixes for scrolling, etc.
17198 Without these, Emacs silently mishandles large integers sometimes.
17199 For example, "C-u 4294967297 M-x recenter" was treated as if
17200 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17202 * xdisp.c (try_window_id): Check Emacs fixnum range before
17203 converting to 'int'.
17205 * window.c (window_scroll_line_based, Frecenter):
17206 Check that an Emacs fixnum is in range before assigning it to 'int'.
17207 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17208 values converted from Emacs fixnums.
17209 (Frecenter): Don't wrap around a line count if it is out of 'int'
17210 range; instead, treat it as an extreme value.
17211 (Fset_window_configuration, compare_window_configurations):
17212 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17214 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17215 that can exceed INT_MAX. Check that EMACS_INT value is in range
17216 before assigning it to the (possibly-narrower) index.
17217 (match_limit): Don't assume that a fixnum can fit in 'int'.
17219 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17222 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17223 (Fvertical_motion): Don't wrap around LINES values that don't fit
17224 in 'int'. Instead, treat them as extreme values. This is good
17225 enough for windows, which can't have more than INT_MAX lines anyway.
17227 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17229 * Require libxml/parser.h to avoid compilation warning.
17231 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17233 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17234 since this reportedly can destroy thread storage.
17236 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17238 * syntax.c (find_defun_start): Update all cache variables if
17239 exiting early (Bug#9401).
17241 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17243 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17245 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17246 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17247 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17249 * term.c (tty_append_glyph): New function.
17250 (produce_stretch_glyph): Static function and its prototype deleted.
17252 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17255 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17257 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17258 when checking :margin (Bug#9390).
17259 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17260 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17261 so that the name doesn't mislead. All uses changed.
17263 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17265 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17268 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17270 * xdisp.c (move_it_to): Don't bail out early when reaching
17271 position beyond to_charpos, if we are scanning backwards.
17272 (move_it_vertically_backward): When DY == 0, make sure we get to
17273 the first character in the line after the newline.
17275 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17277 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17278 (ccl_driver): Do not generate an out-of-range pointer.
17279 (Fccl_execute_on_string): Remove unnecessary check for
17280 integer overflow, noted by Stefan Monnier in
17281 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17282 Remove a FIXME that didn't need fixing.
17283 Simplify the newly-introduced buffer reallocation code.
17285 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17287 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17289 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17291 Integer and memory overflow issues (Bug#9196).
17293 * doc.c (get_doc_string): Rework so that
17294 get_doc_string_buffer_size is the actual buffer size, rather than
17295 being 1 less than the actual buffer size; this makes xpalloc more
17298 * image.c (x_allocate_bitmap_record, cache_image):
17299 * xselect.c (Fx_register_dnd_atom):
17300 Simplify previous changes by using xpalloc.
17302 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17303 since either will do and ptrdiff_t is convenient with xpalloc.
17305 * charset.c (charset_table_size)
17306 (struct charset_sort_data.priority): Now ptrdiff_t.
17307 (charset_compare): Don't overflow if priorities differ greatly.
17308 (Fsort_charsets): Don't assume list length fits in int.
17309 Check for size-calculation overflow when allocating sort data.
17310 (syms_of_charset): Allocate an initial charset table that is
17311 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17313 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17315 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17316 The actual value is always <= INT_MAX, and leaving it unsigned made
17317 overflow checking harder.
17319 * dispextern.h (struct glyph_matrix.rows_allocated)
17320 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17321 with xpalloc. The values are still always <= INT_MAX.
17323 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17325 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17326 (SAFE_NALLOCA): New macro.
17328 * region-cache.c (struct boundary.pos, find_cache_boundary)
17329 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17330 (set_cache_region, invalidate_region_cache)
17331 (revalidate_region_cache, know_region_cache, region_cache_forward)
17332 (region_cache_backward, pp_cache):
17333 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17334 so that ptrdiff_t * can be passed to xpalloc.
17335 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17336 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17337 (pp_cache): Don't assume cache_len fits in int.
17338 * region-cache.h: Adjust extern decls to match.
17340 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not

17354 because xmalloc/xrealloc may not return.
17355 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17356 now that we have proper integer overflow checking.
17357 (record_overlay_string, overlay_strings): Catch overflows when
17358 calculating size of overlay_str_buf.
17360 * callproc.c (Fcall_process): Check for size overflow when
17361 calculating size of args2.
17362 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

17364 require adding more-complicated checks.
17366 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17367 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

17407 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17409 * emacs.c (main): Do not reallocate argv, since there is a null at
17410 the end that can be overwritten, and this way there's no need to
17411 worry about size-calculation overflow.
17412 (sort_args): Check for size-calculation overflow.
17414 * eval.c (init_eval_once, grow_specpdl): Don't update size until

17420 Check for integer overflow.
17421 (x_set_alpha): Do not assume XINT fits in int.
17423 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17424 This is for the members text_lines, text_cols, total_lines, total_cols,
17425 where the system imposes an 'int' limit.
17427 * fringe.c (Fdefine_fringe_bitmap):
17428 Don't update size until alloc works.

17433 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17434 Check for size-calculation overflow.
17435 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17436 do, as we prefer signed integers.
17437 (id_to_widget.max_size, id_to_widget.used)
17438 (xg_store_widget_in_map, xg_remove_widget_from_map)

17441 Use and return ptrdiff_t, not int.
17442 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17443 * gtkutil.h: Change prototypes to match the above.
17445 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

17492 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17493 for command line length. Do not attempt to address one before the
17494 beginning of an array, as that's not portable.

17529 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17530 sizes, since they can exceed INT_MAX in size. Check for size

17540 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17541 (X_LONG_MIN): New macros.
17542 Use them to make the following changes clearer.
17543 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17544 This change doesn't affect the value now, but it may help remind
17545 future maintainers not to raise the value too much later.
17546 (SELECTION_QUANTUM): Remove, replacing with ...
17547 (selection_quantum): ... new function, which avoids overflow.
17549 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17550 assumption that selection length fits in 'int'.

17558 Redo calculations to avoid overflow.
17559 (x_reply_selection_request): When sending hint, ceiling it at

17567 Don't store size until memory allocation succeeds.
17568 (x_get_window_property): Plug memory leak on memory exhaustion.
17569 Don't double-block input; malloc is safe here. Don't assume 2**34
17570 - 4 fits in unsigned long. Add an xassert to check
17571 XGetWindowProperty overflow. Be more careful about overflow
17572 calculations, and distinguish size from memory overflow better.
17573 (receive_incremental_selection): When tracing, don't assume
17574 unsigned int is less than INT_MAX.
17575 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17578 in the range -65535 through -1 fit in an X unsigned short.
17579 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17580 result parameters unless successful. Rely on cons_to_unsigned
17581 to report problems with elements; the old code wasn't right anyway.
17582 (x_check_property_data): Check for int overflow; we cannot use
17583 a wider type due to X limits.

17616 * lisp.h (hash_lookup, hash_put):
17617 * minibuf.c (Ftest_completion):
17618 Use ptrdiff_t for hash table indexes, not int (which is too
17619 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17620 32-bit --with-wide-int hosts).
17622 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17623 Add a FIXME comment about memory leaks.

17631 with outlandish widths.
17632 * character.h (sanitize_tab_width): Rename from sanitize_width,
17633 now that we have two such functions. All uses changed.

17652 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17653 (x_send_scroll_bar_event): Likewise. Check that the size does not
17654 exceed limits imposed by XClientMessageEvent, as well as the usual
17655 ptrdiff_t and size_t limits.
17657 * keyboard.c: Overflow, signedness and related fixes.
17658 (make_lispy_movement): Use same integer type in forward decl
17659 that is used in the definition.
17660 (read_key_sequence, keyremap_step):
17661 Change bufsize argument back to int, undoing my 2011-03-30 change.
17662 We prefer signed types, and int is wide enough here.
17663 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17664 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17665 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17666 length, not size_t. Use ptrdiff_t for index, not int.
17667 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17668 possibility of integer overflow.

17696 Prefer int to unsigned where either will do.
17697 (tiff_handler): New function, combining the cores of the
17698 old tiff_error_handler and tiff_warning_handler.
17699 This function is rewritten to use vsnprintf and thereby avoid
17700 stack buffer overflows. It uses only the features of vsnprintf
17701 that are common to both POSIX and native Microsoft.
17702 (tiff_error_handler, tiff_warning_handler): Use it.
17703 (tiff_load, gif_load, imagemagick_load_image):
17704 Don't assume :index value fits in 'int'.
17705 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17706 (imagemagick_load_image): Check that crop parameters fit into
17707 the integer types that MagickCropImage accepts. Don't assume
17708 Vimagemagick_render_type has a nonnegative value. Don't assume
17709 size_t fits in 'long'.
17710 (gs_load): Use printmax_t to print the widest integers possible.

17713 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17715 * xdisp.c (redisplay_window): Don't force window start if point

17720 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
17721 the display spec is of the form `(space ...)'.
17722 (handle_display_spec): Return the value returned by
17723 handle_single_display_spec, not just 1 or zero.
17724 (handle_single_display_spec): If the display spec is of the form
17725 `(space ...)', and specifies display in the text area, return 2
17727 (try_cursor_movement): Check for the need to scroll more
17728 accurately, and prefer exact match for point under bidi.
17729 Don't advance `row' beyond the last row of the window.
17731 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17732 into disp_prop; all users changed.

17747 buffers, return left-to-right.
17748 (set_cursor_from_row): Consider candidate row a win if its glyph
17749 represents a newline and point is on that newline. Fixes cursor
17750 positioning on the newline at EOL of R2L text within L2R
17751 paragraph, and vice versa.
17752 (try_cursor_movement): Check continued rows, in addition to
17753 continuation rows. Fixes unwarranted scroll when point enters a
17754 continued line of R2L text within an L2R paragraph, or vice versa.
17755 (cursor_row_p): Consider the case of point being equal to
17756 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17757 from the end of a short line to the beginning of a continued line
17758 of R2L text within L2R paragraph.
17759 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

17777 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17778 extra slot even if the purpose is char-code-property-table.
17780 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17782 * xdisp.c (redisplay_window): When computing centering_position,
17783 account for the height of the header line. (Bug#8874)
17785 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17786 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17787 candidate is selected by the mouse, and that candidate has a
17788 composed character under the mouse.
17790 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17791 coordinates reported by pos-visible-in-window-p for a composed
17792 character in column zero.
17794 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

17801 consider it a hit if to_charpos is anywhere in the range of the
17802 composed buffer positions.
17804 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17806 * image.c (gif_load): Don't assume that each subimage has the same
17807 dimensions as the base image. Handle disposal method that is
17808 "undefined" by the gif spec (Bug#9335).
17810 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17812 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17817 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17818 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17819 from an Org mode buffer to a Speedbar frame.
17821 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17822 a composition, take its buffer position from IT->cmp_it.charpos.
17823 Fixes cursor positioning at the beginning of a line that begins
17824 with a composed character.
17826 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17828 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17829 character bidirectional type, use STRONG_L instead. Fixes crashes
17830 in a buffer produced by `describe-categories'.
17832 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17833 members before the level stack, so they would be saved and
17834 restored when copying iterator state. Fixes incorrect reordering
17835 around TABs covered by display properties.
17837 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17839 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17844 (internal_condition_case_2, internal_condition_case_n):
17845 Remove unnecessary aborts (Bug#9081).
17847 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17849 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17850 has no `load' handler, try opening the file locally. (Bug#9311)
17852 2011-08-16 Ken Brown <kbrown@cornell.edu>
17854 * gmalloc.c: Expand comment.
17856 2011-08-16 Eli Zaretskii <eliz@gnu.org>

17870 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17872 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17873 in the static heap.
17874 [CYGWIN] (special_realloc): New function.
17875 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

17907 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17909 * xdisp.c (move_it_in_display_line_to): Don't invoke
17910 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17911 ppos_it. Fixes vertical cursor motion when line beginning is
17912 covered by an image. (Bug#9296)
17914 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17916 * nsterm.h (ns_run_ascript): Declare.

17920 (ns_run_ascript): New function.
17921 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17922 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17923 the event loop. Get status from as_status (Bug#7276).
17925 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17926 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17927 the event loop (Bug#7276).
17929 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17931 * gnutls.c (QCgnutls_bootprop_priority)

17933 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17934 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17935 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17936 (QCgnutls_bootprop_verify_hostname_error)
17937 (QCgnutls_bootprop_callbacks_verify): Rename from
17938 Qgnutls_bootprop_..., all uses changed.

17953 (Fnetwork_interface_list): Allocate in increments of bytes instead
17954 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17955 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17957 (struct ifflag_def): notrailers is smart on OSX.
17958 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17959 Get hardware address with getifaddrs if available.
17961 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17963 * xdisp.c (iterate_out_of_display_property): xassert that
17964 IT->position is set to within IT->object's boundaries. Break from
17965 the loop as soon as EOB is reached; avoids infloops in redisplay
17966 when IT->position is set up wrongly due to some bug.
17967 Set IT->current to match the bidi iterator unconditionally.
17968 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17969 entry. Force push_it to save on the stack the current
17970 buffer/string position, to be restored by pop_it. Fix flags in
17971 the iterator structure wrt the object coming from a display
17972 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17973 properties. (Bug#9284)
17975 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17977 * fontset.c (fontset_get_font_group): Add proper type checks.

17990 no-display-properties-and-no-overlays under bidi display.
17991 Set disp_pos in the bidi iterator to avoid searches for display
17992 properties and overlays.
17994 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17996 * editfns.c (Fset_time_zone_rule): Document relationship with the

18005 restore_point_unwind (Bug#5984).
18007 2011-08-07 Juri Linkov <juri@jurta.org>
18009 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
18010 to show the arg `TIME' instead of `TIMEVAL'.
18012 2011-08-06 Eli Zaretskii <eliz@gnu.org>
18014 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
18015 display property strides EOL and includes a newline, as in
18016 longlines-mode. (Bug#9254)
18017 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18018 word-wrap under bidirectional display. (Bug#9224)
18020 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18021 is non-zero, even if the data buffer is NULL. Fixes a crash in
18022 vertical-motion with longlines-mode. (Bug#9254)
18024 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18026 * bidi.c <bidi_cache_total_alloc>: Now static.
18027 (bidi_initialize): Initialize bidi_cache_total_alloc.
18029 * xdisp.c (display_line): Release buffer allocated for shelved bidi
18032 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18033 amount allocated this far in `bidi_cache_total_alloc'.
18034 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18035 non-zero, only free the data buffer without restoring the cache
18036 contents. All callers changed.
18038 * dispextern.h (bidi_unshelve_cache): Update prototype.
18040 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
18041 (move_it_in_display_line, move_it_to)
18042 (move_it_vertically_backward, move_it_by_lines): Replace the call
18043 to xfree to an equivalent call to bidi_unshelve_cache.
18044 (move_it_in_display_line_to): Fix logic of returning
18045 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
18047 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18049 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
18050 came from a string character with a `cursor' property. (Bug#9229)
18052 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18054 * Makefile.in (LIB_PTHREAD): New variable.
18055 (LIBES): Add LIB_PTHREAD (Bug#9216).
18057 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
18058 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
18060 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
18062 * regex.c (re_iswctype): Remove some redundant boolean conversions.
18064 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
18066 * xterm.c (x_find_topmost_parent): New function.
18067 (x_set_frame_alpha): Find topmost parent window with
18068 x_find_topmost_parent and set the property there also (bug#9181).
18069 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
18071 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
18073 * callproc.c (Fcall_process): Avoid vfork clobbering
18074 the local vars buffer, coding_systems, current_dir.

18087 2011-08-02 Eli Zaretskii <eliz@gnu.org>
18089 Fix slow cursor motion and scrolling in large buffers with

18097 for a display string or property. If found, set DISP_PROP_P
18100 * bidi.c (bidi_fetch_char): Accept an additional argument
18101 DISP_PROP_P, and pass it to compute_display_string_pos.
18102 Only handle text covered by a display string if DISP_PROP_P is returned
18103 non-zero. All callers of bidi_fetch_char changed.
18105 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
18107 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

18111 * keymap.c (Fdefine_key): Fix non-prefix key error message when
18112 last character M-[char] is translated to ESC [char] (bug#7541).
18114 2011-08-02 Kenichi Handa <handa@m17n.org>
18116 * lisp.h (uniprop_table): Extern it.
18118 * chartab.c (uniprop_table): Make it non-static.
18120 2011-08-01 Eli Zaretskii <eliz@gnu.org>
18122 * xdisp.c (forward_to_next_line_start): Accept additional argument
18123 BIDI_IT_PREV, and store into it the state of the bidi iterator had
18125 (reseat_at_next_visible_line_start): Use the bidi iterator state
18126 returned by forward_to_next_line_start to restore the state of
18127 it->bidi_it after backing up to previous newline. (Bug#9212)
18129 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
18131 * regex.c (re_comp): Protoize.
18132 (re_exec): Fix return type.
18133 (regexec): Fix type of `ret'. (Bug#9203)
18135 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18137 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
18138 This is needed if max-image-size is a floating-point number.
18140 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18142 * print.c (print_object): Print empty symbol as ##.

18153 contents (Bug#9176).
18154 (EmacsTooltip -init): Remove bezels and add shadows to
18157 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18158 or scroll bar (Bug#8470).
18160 * nsfont.m (nsfont_open): Remove assignment to voffset and

18164 * nsterm.h (nsfont_info): Remove voffset field.
18166 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
18168 Implement strike-through and overline on NextStep (Bug#8863).
18170 * nsfont.m (nsfont_open): Use underline position provided by font,
18171 instead of hard-coded value of 2.
18172 (nsfont_draw): Call ns_draw_text_decoration instead.

18187 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18189 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18190 Without this fix, if a signal arrives just after memory fills up,
18191 'malloc' might be invoked reentrantly.
18193 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18194 In other words, assume that every image size is allowed, on non-X
18195 hosts. This assumption is probably wrong, but it lets Emacs compile.
18197 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18199 * regex.c (re_iswctype): Convert return values to boolean.

18203 * xdisp.c (compute_display_string_pos): Don't use cached display
18204 string position if the buffer had its restriction changed.
18207 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18209 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18211 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18213 Integer signedness and overflow and related fixes. (Bug#9079)
18215 * bidi.c: Integer size and overflow fixes.
18216 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18217 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18218 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18219 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18220 (bidi_find_other_level_edge):
18221 Use ptrdiff_t instead of EMACS_INT where either will do.
18222 This works better on 32-bit hosts configured --with-wide-int.
18223 (bidi_cache_ensure_space): Check for size-calculation overflow.
18224 Use % rather than repeated addition, for better worst-case speed.
18225 Don't set bidi_cache_size until after xrealloc returns, because it
18227 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18228 (bidi_cache_ensure_space): Also check that the bidi cache size
18229 does not exceed that of the largest Lisp string or buffer. See Eli
18230 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18232 * alloc.c (__malloc_size_t): Remove.
18233 All uses replaced by size_t. See Andreas Schwab's note
18234 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18236 * image.c: Improve checking for integer overflow.
18237 (check_image_size): Assume that f is nonnull, since
18238 it is always nonnull in practice. This is one less thing to
18239 worry about when checking for integer overflow later.
18240 (x_check_image_size): New function, which checks for integer
18241 overflow issues inside X.
18242 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18243 This removes the need for a memory_full check.
18244 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18245 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18246 (xbm_read_bitmap_data): Change locals back to 'int', since
18247 their values must fit in 'int'.
18248 (xpm_load_image, png_load, tiff_load):
18249 Invoke x_create_x_image_and_pixmap earlier,
18250 to avoid much needless work if the image is too large.
18251 (tiff_load): Treat overly large images as if
18252 x_create_x_image_and_pixmap failed, not as malloc failures.
18253 (gs_load): Use x_check_image_size.
18255 * gtkutil.c: Omit integer casts.
18256 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18257 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18259 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18261 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18262 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18263 would wrongly return t on a 64-bit host.
18265 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18266 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18267 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18268 and therefore cause GCC to emit a bogus diagnostic in some cases.
18270 * image.c: Integer signedness and overflow and related fixes.
18271 This is not an exhaustive set of fixes, but it's time to
18272 record what I've got.
18273 (lookup_pixel_color, check_image_size): Remove redundant decls.
18274 (check_image_size): Don't assume that arbitrary EMACS_INT values
18275 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18276 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18277 (tiff_load, imagemagick_load_image):
18278 Check for overflow in size calculations.
18279 (x_create_x_image_and_pixmap): Remove unnecessary test for
18280 xmalloc returning NULL; that can't happen.
18281 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18282 (xpm_color_bucket): Use better integer hashing function.
18283 (xpm_cache_color): Don't possibly over-allocate memory.
18284 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18285 (gif_memory_source):
18286 Use ptrdiff_t, not int or size_t, to record sizes.
18287 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18288 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18289 either works, as we prefer signed integers.
18290 (tiff_read_from_memory, tiff_write_from_memory):
18291 Return tsize_t, not size_t, since that's what the TIFF API wants.
18292 (tiff_read_from_memory): Don't fail simply because the read would
18293 go past EOF; instead, return a short read.
18294 (tiff_load): Omit no-longer-needed casts.
18295 (Fimagemagick_types): Don't assume size fits into 'int'.
18297 Improve hashing quality when configured --with-wide-int.
18298 * fns.c (hash_string): New function, taken from sxhash_string.
18299 Do not discard information about ASCII character case; this
18300 discarding is no longer needed.
18301 (sxhash-string): Use it. Change sig to match it. Caller changed.
18302 * lisp.h: Declare it.
18303 * lread.c (hash_string): Remove, since we now use fns.c's version.
18304 The fns.c version returns a wider integer if --with-wide-int is
18305 specified, so this should help the quality of the hashing a bit.
18307 * emacs.c: Integer overflow minor fix.
18308 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18309 Define only if GNU_LINUX.
18310 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18312 * dispnew.c: Integer signedness and overflow fixes.
18313 Remove unnecessary forward decls, that were a maintenance hassle.
18314 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18316 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18317 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18318 (prepare_desired_row, line_draw_cost):
18319 Use int, not unsigned, where either works.
18320 (save_current_matrix, restore_current_matrix):
18321 Use ptrdiff_t, not size_t, where either works.
18322 (init_display): Check for overflow more accurately, and without
18323 relying on undefined behavior.
18325 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18326 Remove, replacing with the new symbols in lisp.h. All uses changed.
18327 * fileio.c (make_temp_name):
18328 * filelock.c (lock_file_1, lock_file):
18329 * xdisp.c (message_dolog):
18330 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18331 Use pMd etc. instead.
18332 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18333 replacing the pWIDE etc. symbols removed from editfns.c.
18335 * keyboard.h (num_input_events): Now uintmax_t.
18336 This is (very slightly) less likely to mess up due to wraparound.
18339 * buffer.c: Integer signedness fixes.
18340 (alloc_buffer_text, enlarge_buffer_text):
18341 Use ptrdiff_t rather than size_t when either will do, as we prefer
18344 * alloc.c: Integer signedness and overflow fixes.
18345 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18346 (__malloc_size_t): Default to size_t, not to int.
18347 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18348 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18349 Prefer ptrdiff_t to size_t when either would do, as we prefer
18351 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18352 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18353 Now const. Initialize with values that are in range even if char
18355 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18356 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18357 These functions do the right thing with sizes > 2**32.
18358 (check_depth): Now ptrdiff_t, not int.
18359 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18360 Adjust to new way of storing sizes. Check for size overflow bugs
18362 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18363 slightly wrong anyway, as it missed one instance of
18364 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18365 (refill_memory_reserve): Omit needless cast to size_t.
18366 (mark_object_loop_halt): Mark as externally visible.
18368 * xselect.c: Integer signedness and overflow fixes.
18369 (Fx_register_dnd_atom, x_handle_dnd_message):
18370 Use ptrdiff_t, not size_t, since we prefer signed.
18371 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18372 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18373 x_dnd_atoms_size and x_dnd_atoms_length.
18375 * doprnt.c: Prefer signed to unsigned when either works.
18377 * doprnt.c (doprnt):
18379 * xdisp.c (vmessage):
18380 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18381 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18382 prefer signed arithmetic to avoid comparison confusion.
18383 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18384 but is a bit tricky.
18386 Assume freestanding C89 headers, string.h, stdlib.h.
18387 * data.c, doprnt.c, floatfns.c, print.c:
18388 Include float.h unconditionally.
18389 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18390 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18391 * regex.c: Likewise for stddef.h, string.h.
18392 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18393 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18394 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18395 (STDC_HEADERS): Remove obsolete defines.
18396 * sysdep.c: Include limits.h unconditionally.
18398 Assume support for memcmp, memcpy, memmove, memset.
18399 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18400 * regex.c (memcmp, memcpy):
18401 Remove; we assume C89 now.
18403 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18404 (__malloc_safe_bcopy): Remove; no longer needed.
18406 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18407 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18408 well either way, and we prefer signed to unsigned.
18410 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18412 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18413 closes the connection while we're reading (bug#9182).
18415 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18417 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18418 are specified (Bug#9168).
18420 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18422 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18423 Found by GCC static checking and --with-wide-int on a 32-bit host.
18425 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18427 * xdisp.c (compute_display_string_pos): Fix logic of caching
18428 previous display string position. Initialize cached_prev_pos to
18429 -1. Fixes slow-down at the beginning of a buffer.
18431 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18433 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18434 for attrs[LFACE_FONTSET_INDEX].
18436 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18438 * xml.c (parse_region): Remove unused local
18439 that was recently introduced.
18441 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18443 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18444 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18446 * xdisp.c (move_it_in_display_line_to): Record the best matching
18447 position for TO_CHARPOS while scanning the line, and restore it on
18448 exit if none of the characters scanned was an exact match.
18449 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18450 when exact match is impossible due to invisible text, and the
18451 lines are truncated.
18453 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18455 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18458 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18460 Fix a significant slow-down of cursor motion with C-n, C-p,
18461 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18462 auto-repeat under bidi redisplay in fontified buffers.
18463 * xdisp.c (compute_stop_pos_backwards): New function.
18464 (next_element_from_buffer): Call compute_stop_pos_backwards to
18465 find a suitable prev_stop when we find ourselves before
18467 (reseat): Don't look for prev_stop, as that could mean a very long
18469 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18470 <cached_disp_overlay_modiff>: Cache for last found display string
18472 (compute_display_string_pos): Return the cached position if asked
18473 about the same buffer in the same area of character positions, and
18474 the buffer wasn't changed since the time the display string
18475 position was cached.
18477 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18479 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18480 is an integer, which is important for empty lines. (Bug#9149)
18482 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18484 * frame.c (Fmodify_frame_parameters): In tty case, update the
18485 default face if necessary (Bug#4238).
18487 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18489 * editfns.c (Fstring_to_char): No need to explain what a character
18490 is in the docstring (Bug#6576).
18492 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18494 * xml.c (parse_region): Make sure we always return a tree.
18496 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18498 * xml.c (parse_region): If a document contains only comments,
18501 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18503 * xml.c (make_dom): Return comments, too.
18505 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18508 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18509 and the surrounding thread.
18510 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18511 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18512 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18514 * s/openbsd.h (BROKEN_SIGIO): Define.
18515 * unexelf.c (unexec) [__OpenBSD__]:
18516 Don't update the .mdebug section of the Alpha COFF symbol table.
18518 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18520 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18523 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18525 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18526 This fixes some race conditions on the permissions of any newly
18529 * alloc.c (valid_pointer_p): Use pipe, not open.
18530 This fixes some permissions issues when debugging.
18532 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18533 If fchown fails to set both uid and gid, try to set just gid,
18534 as that is sometimes allowed. Adjust the file's mode to eliminate
18535 setuid or setgid bits that are inappropriate if fchown fails.
18537 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18539 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18540 to compare Lisp_Objects.
18541 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18542 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18543 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18545 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18547 * lread.c (read_integer): Unread even EOF character.
18548 (read1): Likewise. Properly record start position of symbol.
18550 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18551 symbol character follows.
18553 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18555 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18556 This works around a problem with the previous change to Fcopy_file.
18557 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18558 and without this change, GCC might complain about discarding
18559 fchown's return value.
18561 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18563 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18565 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18567 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18569 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18571 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18572 it's used from the C level.
18574 * process.c: Use the same condition for POLL_FOR_INPUT in both
18575 keyboard.c and process.c (bug#1858).
18577 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18579 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18580 (Fgnutls_boot): Use it.
18582 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18584 * doc.c (Fsubstitute_command_keys): Revert last change.
18586 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18588 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18589 quotes the next character, and doesn't affect other longer
18590 sequences (bug#8935).
18592 * lread.c (syms_of_lread): Clarify that is isn't only
18593 `eval-buffer' and `eval-defun' that's affected by
18594 `lexical-binding' (bug#8460).
18596 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18598 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18599 bidi redisplay when a line includes both an image and is truncated.
18601 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18603 Fix minor problems found by static checking.
18604 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18605 (elsz): Now a signed constant, not a size_t var. We prefer signed
18606 types to unsigned, to avoid integer comparison confusion. Without
18607 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18608 "cannot optimize loop, the loop counter may overflow", a symptom
18610 * indent.c (Fvertical_motion): Mark locals as initialized.
18611 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18613 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18615 * search.c (Fre_search_backward): Mention `case-fold-search' in
18616 all the re_search_* functions (bug#8138).
18618 * keyboard.c (Fopen_dribble_file): Document when the file is
18621 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18623 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18626 Support bidi reordering of display and overlay strings.
18627 * xdisp.c (compute_display_string_pos)
18628 (compute_display_string_end): Accept additional argument STRING.
18629 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18630 (reseat_to_string): Initialize bidi_it->string.s and
18631 bidi_it->string.schars.
18632 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18633 NULL (avoids a crash in bidi_paragraph_init).
18634 Initialize itb.string.lstring.
18635 (init_iterator): Call bidi_init_it only of a valid
18636 buffer position was specified. Initialize paragraph_embedding to
18638 (reseat_to_string): Initialize the bidi iterator.
18639 (display_string): If we need to ignore text properties of
18640 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18641 original value of -1 will not work with bidi.)
18642 (compute_display_string_pos): First arg is now struct
18643 `text_pos *'; all callers changed. Support display properties on
18645 (compute_display_string_end): Support display properties on Lisp
18647 (init_iterator, reseat_1, reseat_to_string): Initialize the
18648 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18649 when iterating on a string not from display properties).
18650 (compute_display_string_pos, compute_display_string_end):
18651 Fix calculation of the object to scan. Fixes an error when using
18653 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18654 base_level_stop; instead, set base_level_stop to BEGV.
18655 Fixes crashes in vertical-motion.
18656 (next_element_from_buffer): Improve commentary for when
18657 the iterator is before prev_stop.
18658 (init_iterator): Initialize bidi_p from the default value of
18659 bidi-display-reordering, not from buffer-local value. Use the
18660 buffer-local value only if initializing for buffer iteration.
18661 (handle_invisible_prop): Support invisible properties on strings
18662 that are being bidi-reordered.
18663 (set_iterator_to_next): Support bidi reordering of C strings and
18665 (next_element_from_string): Support bidi reordering of Lisp
18667 (handle_stop_backwards): Support Lisp strings as well.
18668 (display_string): Support display of R2L glyph rows.
18669 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18670 (init_iterator): Don't initialize it->bidi_p for strings
18672 (reseat_to_string): Initialize it->bidi_p for strings here.
18673 (next_element_from_string, next_element_from_c_string)
18674 (next_element_from_buffer): Add xassert's for correspondence
18675 between IT's object being iterated and it->bidi_it.string
18677 (face_before_or_after_it_pos): Support bidi iteration.
18678 (next_element_from_c_string): Handle the case of the first string
18679 character that is not the first one in the visual order.
18680 (get_visually_first_element): New function, refactored from common

19134 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
19135 (clone_per_buffer_values): Don't assume that
19136 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
19137 This isn't true in general, and it's particularly not true
19138 if Emacs is configured with --with-wide-int.
19139 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
19140 New macros, used in the buffer.c change.

19176 Random fixes. E.g., (random) never returned negative values.
19177 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19178 subseconds part to the entropy, as that's a bit more random.
19179 Prefer signed to unsigned, since the signedness doesn't matter and
19180 in general we prefer signed. When given a limit, use a
19181 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19182 latter isn't right if USE_2_TAGS_FOR_INTS.
19183 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19184 not 0..VALMASK. Don't discard "excess" bits that random () returns.
19186 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
19188 * textprop.c (text_property_stickiness):
19189 Obey Vtext_property_default_nonsticky.

19196 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19197 This is more efficient than Ffile_directory_p and avoids a minor race.
19199 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19201 * buffer.c (Foverlay_put): Say what the return value is
19204 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19205 is a directory before asking whether to use the file name
19207 (barf_or_query_if_file_exists): Make the "File is a directory"
19208 error be more correct.
19210 * fns.c (Frequire): Remove the mention of the .gz files, since
19211 that's installation-specific, but keep the mention of
19212 `get-load-suffixes'.

19224 Qgnutls_bootprop_verify_error (which is no longer used).
19226 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19227 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19228 Also (re)move comments that are misplaced or no longer relevant.
19230 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
19232 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

19329 * eval.c (struct backtrace): Simplify and port the data structure.
19330 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19331 signed bit field, as this assumption is not portable and it makes
19332 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19333 "char debug_on_exit : 1" as this is not portable either; instead,
19334 use the portable "unsigned int debug_on_exit : 1". Remove unused
19335 member evalargs. Remove obsolete comments about cc bombing out.
19337 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19559 * dispnew.c (window_to_frame_vpos):
19560 * xfns.c (unwind_create_frame):
19561 * xterm.c (x_check_font): Remove unused local.
19562 * scroll.c (CHECK_BOUNDS):
19563 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19564 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19565 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19566 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19567 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19569 (debug_method_add): Use va_list and vsprintf rather than relying
19570 on undefined behavior with wrong number of arguments.
19571 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19572 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19573 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19574 since we're not interested in debugging glyphs with old libraries.
19575 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19576 GCC 4.6.0's static checking.
19578 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19580 Integer overflow and signedness fixes (Bug#8873).
19581 A few related buffer overrun fixes, too.
19583 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
19585 * dispextern.h (struct face.stipple):
19586 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
19587 (x_bitmap_mask, x_allocate_bitmap_record)
19588 (x_create_bitmap_from_data, x_create_bitmap_from_file)
19589 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19590 (x_create_bitmap_from_xpm_data):
19591 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19592 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19594 * xfaces.c (load_pixmap):
19595 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19596 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19597 (.bitmaps_last, struct x_output.icon_bitmap):
19598 Use ptrdiff_t, not int, for bitmap indexes.
19599 (x_allocate_bitmap_record): Check for size overflow.
19600 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19602 Use ptrdiff_t, not int, for overlay counts.
19603 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19604 * editfns.c (overlays_around, get_pos_property):
19605 * textprop.c (get_char_property_and_overlay):
19606 * xdisp.c (next_overlay_change, note_mouse_highlight):
19607 * xfaces.c (face_at_buffer_position):
19608 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19609 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19610 (Fnext_overlay_change, Fprevious_overlay_change)
19611 (mouse_face_overlay_overlaps, Foverlays_in):
19612 Use ptrdiff_t, not int, for sizes.
19613 (overlays_at, overlays_in): Check for size-calculation overflow.
19615 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19617 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19618 (x_session_initialize): Do not assume string length fits in int.
19620 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19621 This is unlikely, but can occur if DPI is outlandish.
19623 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19624 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19626 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19627 * xrdb.c (magic_file_p, search_magic_path):
19628 Omit last arg SUFFIX; it was always 0. All callers changed.
19629 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19631 * xfont.c (xfont_match): Avoid need for strlen.
19633 * xfns.c: Don't assume strlen fits in int.
19634 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19636 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19637 not unsigned long, as we prefer signed integers. All callers changed.
19638 Detect integer overflow in repeat count.
19639 (message_dolog): Don't assume print length fits in 39 bytes.
19640 (display_mode_element): Don't assume strlen fits in int.
19642 * termcap.c: Don't assume sizes fit in int and never overflow.
19643 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19644 (gobble_line): Check for size-calculation overflow.
19646 * minibuf.c (Fread_buffer):
19647 * lread.c (intern, intern_c_string):
19648 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19649 Don't assume string length fits in int.
19651 * keyboard.c (parse_tool_bar_item):
19652 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19654 * font.c: Don't assume string length fits in int.
19655 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19656 Use ptrdiff_t, not int.
19657 (font_intern_prop): Don't assume string length fits in int.
19658 Don't assume integer property fits in fixnum.
19659 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19661 * filelock.c: Fix some buffer overrun and integer overflow issues.
19662 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19663 Reformulate so as not to need the command string.
19664 Invoke gzip -cd rather than gunzip, as it's more portable.
19665 (lock_info_type, lock_file_1, lock_file):
19666 Don't assume pid_t and time_t fit in unsigned long.
19667 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19668 (current_lock_owner): Prefer signed type for sizes.
19669 Use memcpy, not strncpy, where memcpy is what is really wanted.
19670 Don't assume (via atoi) that time_t and pid_t fit in int.
19671 Check for time_t and/or pid_t out of range, e.g., via a network share.
19672 Don't alloca where an auto var works fine.
19674 * fileio.c: Fix some integer overflow issues.
19675 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19676 Don't assume string length fits in int.
19677 (directory_file_name): Don't assume string length fits in long.
19678 (make_temp_name): Don't assume pid fits in int, or that its print
19679 length is less than 20.
19681 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19683 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19685 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19687 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19688 We prefer signed integers, even for size calculations.
19690 * emacs.c: Don't assume string length fits in 'int'.
19691 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19692 (main): Don't invoke strlen when not needed.
19694 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19695 (XD_DEBUG_MESSAGE): Don't waste a byte.
19697 * callproc.c (getenv_internal_1, getenv_internal)
19698 (Fgetenv_internal):
19699 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19701 * lread.c (invalid_syntax): Omit length argument.
19702 All uses changed. This doesn't fix a bug, but it simplifies the
19703 code away from its former Hollerith-constant appearance, and it's
19704 one less 'int' to worry about when looking at integer-overflow issues.
19705 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19707 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19708 This didn't break anything, but it didn't help either.
19709 It's confusing to put a bogus integer in a place where the actual
19710 value does not matter.
19711 (LIST_END_P): Remove unused macro and its bogus comment.
19712 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19714 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19715 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19717 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19718 We prefer signed types, and the value cannot exceed the EMACS_INT
19719 range anyway (because otherwise the length would not be representable).
19720 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19721 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19722 This avoids a GCC warning when WIDE_EMACS_INT.
19724 * indent.c (sane_tab_width): New function.
19725 (current_column, scan_for_column, Findent_to, position_indentation)
19726 (compute_motion): Use it. This is just for clarity.
19727 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19729 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19731 * lisp.h (lint_assume): New macro.
19732 * composite.c (composition_gstring_put_cache):
19733 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19735 * editfns.c, insdel.c:
19736 Omit unnecessary forward decls, to simplify future changes.
19738 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19740 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19742 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19743 Use much-faster test for byte-length change.
19744 Don't assume string byte-length fits in 'int'.
19745 Check that character arg fits in 'int'.
19746 (mapcar1): Declare byte as byte, for clarity.
19748 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19750 * fns.c (concat): Catch string overflow earlier.
19751 Do not rely on integer wraparound.
19753 * dispextern.h (struct it.overlay_strings_charpos)
19754 (struct it.selective): Now EMACS_INT, not int.
19755 * xdisp.c (forward_to_next_line_start)
19756 (back_to_previous_visible_line_start)
19757 (reseat_at_next_visible_line_start, next_element_from_buffer):
19758 Don't arbitrarily truncate the value of 'selective' to int.
19760 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19762 * composite.c: Don't truncate sizes to 'int'.
19763 (composition_gstring_p, composition_reseat_it)
19764 (composition_adjust_point): Use EMACS_INT, not int.
19765 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19766 not EMACS_UINT, for indexes.
19768 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19770 * buffer.c: Include <verify.h>.
19771 (struct sortvec.priority, struct sortstr.priority):
19772 Now EMACS_INT, not int.
19773 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19774 (struct sortstr.size, record_overlay_string)
19775 (struct sortstrlist.size, struct sortlist.used):
19776 Don't truncate size to int.
19777 (record_overlay_string): Check for size-calculation overflow.
19778 (init_buffer_once): Check at compile-time, not run-time.
19780 2011-06-22 Jim Meyering <meyering@redhat.com>
19782 Don't leak an XBM-image-sized buffer
19783 * image.c (xbm_load): Free the image buffer after using it.
19785 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19788 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19789 that Sun C diagnosed.
19790 * fns.c (secure_hash): Fix pointer signedness issue.
19791 * intervals.c (static_offset_intervals): New function.
19792 (offset_intervals): Use it.
19794 2011-06-21 Leo Liu <sdl.web@gmail.com>
19797 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19800 * fns.c (secure_hash): Rename from crypto_hash_function and change
19801 the first arg to accept symbols.
19802 (Fsecure_hash): New primitive.
19803 (syms_of_fns): New symbols.
19805 2011-06-20 Deniz Dogan <deniz@dogan.se>
19807 * process.c (Fset_process_buffer): Clarify return value in
19810 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19812 * dispnew.c (add_window_display_history): Use BVAR.
19814 * xdisp.c (debug_method_add): Use BVAR.
19815 (check_window_end, dump_glyph_matrix, dump_glyph)
19816 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19818 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19821 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19822 check till after the cache is created in init_frame_faces.
19824 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19826 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19828 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19830 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19831 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19832 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19834 Improve buffer-overflow checking (Bug#8873).
19835 * fileio.c (Finsert_file_contents):
19836 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19837 Remove the old (too-loose) buffer overflow checks.
19838 They weren't needed, since make_gap checks for buffer overflow.
19839 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19840 The old code merely checked for Emacs fixnum overflow, and relied
19841 on undefined (wraparound) behavior. The new code avoids undefined
19842 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19844 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19845 Tune. Don't use wider integers than needed. Don't use alloca.
19846 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19848 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19850 * insdel.c, lisp.h (buffer_overflow): New function.
19851 (insert_from_buffer_1, replace_range, replace_range_2):
19852 * insdel.c (make_gap_larger):
19853 * editfns.c (Finsert_char):
19854 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19856 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19858 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19860 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19862 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19863 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19865 * fileio.c: Don't assume EMACS_INT fits in off_t.
19866 (emacs_lseek): New static function.
19867 (Finsert_file_contents, Fwrite_region): Use it.
19868 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19870 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19872 * fns.c: Don't overflow int when computing a list length.
19873 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19874 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19875 truncation on 64-bit hosts. Check for QUIT every
19876 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19877 faster and is responsive enough.
19878 (Flength): Report an error instead of overflowing an integer.
19879 (Fsafe_length): Return a float if the value is not representable
19880 as a fixnum. This shouldn't happen except in contrived situations.
19881 (Fnthcdr, Fsort): Don't assume list length fits in int.
19882 (Fcopy_sequence): Don't assume vector length fits in int.
19884 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19885 (header_size, word_size): New constants.
19886 (allocate_vectorlike): Don't check size overflow here.
19887 (allocate_vector): Check it here instead, since this is the only
19888 caller of allocate_vectorlike that could cause overflow.
19889 Check that the new vector's length is representable as a fixnum.
19891 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19892 The previous code was bogus. For example, next_almost_prime (32)
19893 returned 39, which is undesirable as it is a multiple of 3; and
19894 next_almost_prime (24) returned 25, which is a multiple of 5 so
19895 why was the code bothering to check for multiples of 7?
19897 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19899 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19901 Variadic C functions now count arguments with ptrdiff_t.
19902 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19903 Back then I didn't know that the Emacs coding style prefers signed int.
19904 Also, in the meantime I found a few more instances where arguments
19905 were being counted with int, which may truncate counts on 64-bit
19906 machines, or EMACS_INT, which may be unnecessarily wide.
19907 * lisp.h (struct Lisp_Subr.function.aMANY)
19908 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19909 Arg counts are now ptrdiff_t, not size_t.
19910 All variadic functions and their callers changed accordingly.
19911 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19912 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19913 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19914 * callint.c (Fcall_interactively): Check arg count for overflow,
19915 to avoid potential buffer overrun. Use signed char, not 'int',
19916 for 'varies' array, so that we needn't bother to check its size
19917 calculation for overflow.
19918 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19919 * eval.c (apply_lambda):
19920 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19921 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19922 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19924 * callint.c (Fcall_interactively): Don't use index var as event count.
19926 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19927 * mem-limits.h (SIZE): Remove; no longer used.
19929 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19931 Remove unnecessary casts.
19932 * xterm.c (x_term_init):
19933 * xfns.c (x_set_border_pixel):
19934 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19935 These aren't needed now that we assume ANSI C.
19937 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19938 It's more likely to cause problems (due to unsigned overflow)
19941 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19943 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19945 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19947 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19949 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19951 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19953 GLYPH_CODE_FACE returns EMACS_INT, not int.
19954 * dispextern.h (merge_faces):
19955 * xfaces.c (merge_faces):
19956 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19957 Don't assume EMACS_INT fits in int.
19959 * character.h (CHAR_VALID_P): Remove unused parameter.
19960 * fontset.c, lisp.h, xdisp.c: All uses changed.
19962 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19964 * fns.c (concat): Minor tuning based on overflow analysis.
19965 This doesn't fix any bugs. Use int to hold character, instead
19966 of constantly refetching from Emacs object. Use XFASTINT, not
19967 XINT, for value known to be a character. Don't bother comparing
19968 a single byte to 0400, as it's always less.
19970 * floatfns.c (Fexpt):
19971 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19973 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19976 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19978 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19979 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19980 incorrectly succeed when S was a string, because 4294967386 was
19981 truncated before it was used.
19983 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19984 Otherwise, an out-of-range integer could cause undefined behavior
19987 * composite.c: Use int, not EMACS_INT, for characters.
19988 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19989 EMACS_INT, for values that are known to be in character range.
19990 This doesn't fix any bugs but is the usual style inside Emacs and
19991 may generate better code on 32-bit machines.
19993 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19994 This is for reasons similar to the recent CHAR_STRING fix.
19995 * charset.c (Fencode_char): Check that character arg is actually
19996 a character. Pass an int to ENCODE_CHAR.
19997 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19998 wider than 'int', as a compile-time check to prevent future regressions
20001 * character.c (char_string): Remove unnecessary casts.
20003 Make sure a 64-bit char is never passed to CHAR_STRING.
20004 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20005 by silently ignoring the top 32 bits, allowing some values
20006 that were far too large to be valid characters.
20007 * character.h: Include <verify.h>.
20008 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20009 arguments are no wider than unsigned, as a compile-time check
20010 to prevent future regressions in this area.
20012 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20013 (Fsubst_char_in_region):
20015 * xdisp.c (decode_mode_spec_coding):
20016 Adjust to CHAR_STRING's new requirement.
20017 * editfns.c (Finsert_char, Fsubst_char_in_region):
20018 * fns.c (concat): Check that character args are actually
20019 characters. Without this test, these functions did the wrong
20020 thing with wildly out-of-range values on 64-bit hosts.
20022 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20023 These casts should not be needed on 32-bit hosts, either.
20024 * keyboard.c (read_char):
20025 * lread.c (Fload): Remove casts to unsigned.
20027 * lisp.h (UNSIGNED_CMP): New macro.
20028 This fixes comparison bugs on 64-bit hosts.
20029 (ASCII_CHAR_P): Use it.
20030 * casefiddle.c (casify_object):
20031 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20032 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20033 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20034 * dispextern.h (FACE_FROM_ID):
20035 * keyboard.c (read_char): Use UNSIGNED_CMP.
20037 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20038 not to EMACS_INT, to avoid GCC warning.
20040 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20042 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20043 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20044 isn't needed on 32-bit machines.
20046 * buffer.c (Fgenerate_new_buffer_name):
20047 Use EMACS_INT for count, not int.
20048 (advance_to_char_boundary): Return EMACS_INT, not int.
20050 * data.c (Qcompiled_function): Now static.
20052 * window.c (window_body_lines): Now static.
20054 * image.c (gif_load): Rename local to avoid shadowing.
20056 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20057 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20058 * alloc.c (make_save_value): Integer argument is now of type
20059 ptrdiff_t, not int.
20060 (mark_object): Use ptrdiff_t, not int.
20061 * lisp.h (pD): New macro.
20062 * print.c (print_object): Use it.
20064 * alloc.c: Use EMACS_INT, not int, to count objects.
20065 (total_conses, total_markers, total_symbols, total_vector_size)
20066 (total_free_conses, total_free_markers, total_free_symbols)
20067 (total_free_floats, total_floats, total_free_intervals)
20068 (total_intervals, total_strings, total_free_strings):
20069 Now EMACS_INT, not int. All uses changed.
20070 (Fgarbage_collect): Compute overall total using a double, so that
20071 integer overflow is less likely to be a problem. Check for overflow
20072 when converting back to an integer.
20073 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20074 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20075 These were 'int' variables that could overflow on 64-bit hosts;
20076 they were never used, so remove them instead of repairing them.
20077 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20078 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20079 Previously, this ceilinged at INT_MAX, but that doesn't work on
20081 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20083 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20084 (allocate_vectorlike): Check for ptrdiff_t overflow.
20085 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20086 when a (possibly-narrower) signed value would do just as well.
20087 We prefer using signed arithmetic, to avoid comparison confusion.
20089 * alloc.c: Catch some string size overflows that we were missing.
20090 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20091 for convenience in STRING_BYTES_MAX.
20092 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20093 The definition here is exact; the one in lisp.h was approximate.
20094 (allocate_string_data): Check for string overflow. This catches
20095 some instances we weren't catching before. Also, it catches
20096 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20097 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20098 and ptrdiff_t and EMACS_INT are both 64 bits.
20100 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20101 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20102 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20104 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20106 * alloc.c (Fmake_string): Check for out-of-range init.
20108 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20110 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20112 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20114 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

20132 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20134 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

20138 * frame.c (make_frame): Call other_buffer_safely instead of
20141 * window.c (temp_output_buffer_show): Call display_buffer with
20142 second argument Vtemp_buffer_show_specifiers and reset latter
20143 immediately after the call.
20144 (Vtemp_buffer_show_specifiers): New variable.
20145 (auto_window_vscroll_p, next_screen_context_lines)
20146 (Vscroll_preserve_screen_position): Remove leading asterisks from

20691 were just reseat()'ed to a new position.
20693 * xdisp.c (set_cursor_from_row): Set start and stop points
20694 according to the row's direction when priming the loop that looks

20709 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20710 value of a `display' property is a "replacing spec".
20711 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20712 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20713 the display property, but just return a value indicating whether
20714 the display property will replace the characters it covers.
20715 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and

20742 * gnutls.c: Use Emacs's memory allocators.
20743 Without this change, the gnutls library would invoke malloc etc.
20744 directly, which causes problems on non-SYNC_INPUT hosts, and which
20745 runs afoul of improving memory_full behavior. (Bug#8761)
20746 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20747 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20748 xfree instead of the default malloc, realloc, free.
20749 (Fgnutls_boot): No need to check for memory allocation failure,
20750 since xmalloc does that for us.

20779 need to be updated by these changes.
20780 * fns.c (make_hash_table, maybe_resize_hash_table):
20781 Check for integer overflow with large hash tables.
20782 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20783 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20784 (SXHASH_REDUCE): New macro.
20785 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20786 Use it instead of discarding useful hash info with large hash values.

20788 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20789 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20790 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20791 Rewrite to use FIXNUM_BITS, as this simplifies things.
20792 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20793 Adjust signatures to match updated version of code.
20794 (consing_since_gc): Now EMACS_INT, since a single hash table can
20795 use more than INT_MAX bytes.

20862 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20863 (CCL_CODE_MIN): New macro.
20865 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20867 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20869 * eval.c (Qdebug): Now static.
20870 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20871 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20872 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20874 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20876 * image.c: Various fixes to ImageMagick code comments.
20877 (Fimagemagick_types): Doc fix.
20879 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20881 Minor fixes prompted by GCC 4.6.0 warnings.
20883 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20885 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20886 (x_clipboard_manager_save_all): Move extern decl to ...
20887 * xterm.h: ... here, so that it can be checked for consistency.
20889 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20891 * xselect.c (x_clipboard_manager_save_frame)
20892 (x_clipboard_manager_save_all): New functions.
20893 (Fx_clipboard_manager_save): Lisp function deleted.
20895 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20896 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20898 * xterm.h: Update prototype.
20900 2011-05-28 William Xu <william.xwl@gmail.com>
20902 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20903 exiting (Bug#8239).
20905 2011-05-28 Jim Meyering <meyering@redhat.com>
20907 Avoid a sign-extension bug in crypto_hash_function.
20908 * fns.c (to_uchar): Define.
20909 (crypto_hash_function): Use it to convert some newly-signed
20910 variables to unsigned, to avoid sign-extension bugs. For example,
20911 without this change, (md5 "truc") would evaluate to
20912 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20913 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20914 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20916 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20918 Integer overflow fixes.
20920 * dbusbind.c: Serial number integer overflow fixes.
20921 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20922 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20923 to hold a serial number that is too large for a fixnum.
20924 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20925 Check for serial numbers out of range. Decode any serial number
20926 that was so large that it became a float. (Bug#8722)
20928 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20929 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20930 Use XFASTINT rather than XUINT when numbers are nonnegative.
20931 (xd_append_arg, Fdbus_method_return_internal):
20932 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20933 arguments, check that Lisp number is nonnegative, rather than
20934 silently wrapping negative numbers around. (Bug#8722)
20935 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20938 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20940 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20942 ccl: Add integer overflow checks.
20943 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20944 (IN_INT_RANGE): New macros.
20945 (ccl_driver): Use them to check for integer overflow when
20946 decoding a CCL program. Many of the new checks are whether XINT (x)
20947 fits in int; it doesn't always, on 64-bit hosts. The new version
20948 doesn't catch all possible integer overflows, but it's an
20949 improvement. (Bug#8719)
20951 * alloc.c (make_event_array): Use XINT, not XUINT.
20952 There's no need for unsigned here.
20954 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20955 This follows up to the 2011-05-06 change that substituted uintptr_t
20956 for EMACS_INT. This case wasn't caught back then.
20958 Rework Fformat to avoid integer overflow issues.
20959 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20960 now (part of C89). Include <verify.h>.
20961 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20962 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20963 (Fformat): Avoid the prepass trying to compute sizes; it was only
20964 approximate and thus did not catch overflow reliably. Instead, walk
20965 through the format just once, formatting and computing sizes as we go,
20966 checking for integer overflow at every step, and allocating a larger
20967 buffer as needed. Keep track separately whether the format is
20968 multibyte. Keep only the most-recently calculated precision, rather
20969 than them all. Record whether each argument has been converted to
20970 string. Use EMACS_INT, not int, for byte and char and arg counts.
20971 Support field widths and precisions larger than INT_MAX. Avoid
20972 sprintf's undefined behavior with conversion specifications such as %#d
20973 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20974 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20975 formatting out-of-range floating point numbers with int
20976 formats. (Bug#8668)
20978 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20980 * data.c: Avoid integer truncation in expressions involving floats.
20981 * data.c: Include <intprops.h>.
20982 (arith_driver): When there's an integer overflow in an expression
20983 involving floating point, convert the integers to floating point
20984 so that the resulting value does not suffer from catastrophic
20985 integer truncation. For example, on a 64-bit host (* 4
20986 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20987 Do not rely on undefined behavior after integer overflow.
20989 merge count_size_as_multibyte, parse_str_to_multibyte
20990 * character.c, character.h (count_size_as_multibyte):
20991 Rename from parse_str_to_multibyte; all uses changed.
20992 Check for integer overflow.
20993 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20994 since it's now a duplicate of the other. This is more of
20995 a character than a buffer op, so better that it's in character.c.
20996 * fns.c, print.c: Adjust to above changes.
20998 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
21000 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
21002 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21004 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21005 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
21006 (x_clipboard_manager_save): Now static.
21007 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
21009 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21010 (crypto_hash_function): Now static.
21011 Fix pointer signedness problems. Avoid unnecessary initializations.
21013 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21015 * termhooks.h (Vselection_alist): Make it terminal-local.
21017 * terminal.c (create_terminal): Initialize it.
21019 * xselect.c: Support for clipboard managers.
21020 (Vselection_alist): Move to termhooks.h as terminal-local var.
21021 (LOCAL_SELECTION): New macro.
21022 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21023 (symbol_to_x_atom): Remove gratuitous arg.
21024 (x_handle_selection_request, lisp_data_to_selection_data)
21025 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21026 (x_own_selection, x_get_local_selection, x_convert_selection):
21027 New arg, specifying work frame. Use terminal-local Vselection_alist.
21028 (some_frame_on_display): Delete unused function.
21029 (Fx_own_selection_internal, Fx_get_selection_internal)
21030 (Fx_disown_selection_internal, Fx_selection_owner_p)
21031 (Fx_selection_exists_p): New optional frame arg.
21032 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21033 (x_handle_selection_clear): Don't treat other terminals with the
21034 same keyboard specially. Use the terminal-local Vselection_alist.
21035 (x_clear_frame_selections): Use Frun_hook_with_args.
21037 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21039 * xterm.h: Add support for those atoms.
21041 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21043 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21044 (converted_selections, conversion_fail_tag): New global variables.
21045 (x_selection_request_lisp_error): Free the above.
21046 (x_get_local_selection): Remove unnecessary code.
21047 (x_reply_selection_request): Args changed; handle arbitrary array
21048 of converted selections stored in converted_selections.
21049 Separate the XChangeProperty and SelectionNotify steps.
21050 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21051 (x_convert_selection): New function.
21052 (x_handle_selection_event): Simplify.
21053 (x_get_foreign_selection): Don't ignore incoming requests while
21054 waiting for an answer; this will fail when we implement
21055 SAVE_TARGETS, and seems unnecessary anyway.
21056 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21057 (Vx_sent_selection_functions): Doc fix.
21059 2011-05-26 Leo Liu <sdl.web@gmail.com>
21061 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21063 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21065 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21067 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21068 for fringe update if it has periodic bitmap.
21069 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21070 and fringe_bitmap_periodic_p.
21072 * fringe.c (get_fringe_bitmap_data): New function.
21073 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21074 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21075 row. Mark glyph row for fringe update if periodicity changed.
21077 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21078 for fringe update unless it has periodic bitmap.
21080 2011-05-25 Kenichi Handa <handa@m17n.org>
21082 * xdisp.c (get_next_display_element): Set correct it->face_id for
21083 a static composition.
21085 2011-05-24 Leo Liu <sdl.web@gmail.com>
21088 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21090 * fns.c (crypto_hash_function, Fsha1): New function.
21091 (Fmd5): Use crypto_hash_function.
21092 (syms_of_fns): Add Ssha1.
21094 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21096 * gnutls.c: Remove unused macros.
21097 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21098 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21099 Remove macros that are defined and never used.
21100 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21102 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21104 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21105 (Fx_get_selection_internal): Minor cleanup.
21106 (Fx_own_selection_internal): Rename arguments for consistency with
21109 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21111 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21113 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21115 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21117 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21119 * dispnew.c (scrolling_window): Don't exclude the case that the
21120 last enabled row in the desired matrix touches the bottom boundary.
21122 2011-05-21 Glenn Morris <rgm@gnu.org>
21124 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21125 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21126 and add some more files.
21128 2011-05-20 Eli Zaretskii <eliz@gnu.org>
21130 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21131 report_file_error introduced by the change from 2011-05-07.
21133 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21135 * systime.h (Time): Define only if emacs is defined.
21136 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21137 where the include path doesn't have X11/X.h by default. See
21138 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21140 2011-05-20 Kenichi Handa <handa@m17n.org>
21142 * composite.c (find_automatic_composition): Fix previous change.
21144 2011-05-20 Glenn Morris <rgm@gnu.org>
21146 * lisp.mk: New file, split from Makefile.in.
21147 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21148 (shortlisp): Remove.
21149 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21151 2011-05-19 Glenn Morris <rgm@gnu.org>
21153 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21154 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21155 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21156 (lisp): Set the order to that of loadup.el.
21157 (shortlisp): Make it a copy of $lisp.
21158 (SOME_MACHINE_LISP): Remove.
21159 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21160 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21162 2011-05-18 Kenichi Handa <handa@m17n.org>
21164 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21165 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21166 (find_automatic_composition): Mostly rewrite for efficiency.
21168 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21170 * makefile.w32-in: Update dependencies.
21172 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21174 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21175 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21177 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21179 Fix some integer overflow issues, such as string length overflow.
21181 * insdel.c (count_size_as_multibyte): Check for string overflow.
21183 * character.c (lisp_string_width): Check for string overflow.
21184 Use EMACS_INT, not int, for string indexes and lengths; in
21185 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21186 the resulting string length overflows an EMACS_INT; instead,
21187 report a string overflow if no precision given. When checking for
21188 precision exhaustion, use a check that cannot possibly have
21189 integer overflow. (Bug#8675)
21190 * character.h (lisp_string_width): Adjust to new signature.
21192 * alloc.c (string_overflow): New function.
21193 (Fmake_string): Use it. This doesn't change behavior, but saves
21194 a few bytes and will simplify future changes.
21195 * character.c (string_escape_byte8): Likewise.
21196 * lisp.h (string_overflow): New decl.
21198 Fixups, following up to the user-interface timestamp change.
21199 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21200 for UI timestamps, instead of unsigned long.
21201 * msdos.c (mouse_get_pos): Likewise.
21202 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21203 * w32gui.h (Time): Define by including "systime.h" rather than by
21204 declaring it ourselves. (Bug#8664)
21206 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21207 * image.c (clear_image_cache): Likewise.
21209 * term.c (term_mouse_position): Don't assume time_t wraparound.
21211 Be more systematic about user-interface timestamps.
21212 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21213 and sometimes 'EMACS_UINT', to represent these timestamps.
21214 This change causes it to use 'Time' uniformly, as that's what X uses.
21215 This makes the code easier to follow, and makes it easier to catch
21216 integer overflow bugs such as Bug#8664.
21217 * frame.c (Fmouse_position, Fmouse_pixel_position):
21218 Use Time, not unsigned long, for user-interface timestamps.
21219 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21220 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21221 * keyboard.h (last_event_timestamp): Likewise.
21222 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21223 * menu.h (xmenu_show): Likewise.
21224 * term.c (term_mouse_position): Likewise.
21225 * termhooks.h (struct input_event.timestamp): Likewise.
21226 (struct terminal.mouse_position_hook): Likewise.
21227 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21228 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21229 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21230 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21231 what it was before.
21232 * menu.h, termhooks.h: Include "systime.h", for Time.
21234 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21235 Don't assume that the difference between two unsigned long values
21236 can fit into an integer. At this point, we know button_down_time
21237 <= event->timestamp, so the difference must be nonnegative, so
21238 there's no need to cast the result if double-click-time is
21239 nonnegative, as it should be; check that it's nonnegative, just in
21240 case. This bug is triggered when events are more than 2**31 ms
21241 apart (about 25 days). (Bug#8664)
21243 * xselect.c (last_event_timestamp): Remove duplicate decl.
21244 (x_own_selection): Remove needless cast to unsigned long.
21246 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21247 that always fit in int. Use a sentinel instead of a counter, to
21248 avoid a temp and to allay GCC's concerns about possible int overflow.
21249 * frame.h (struct frame): Use int for menu_bar_items_used
21250 instead of EMACS_INT, since it always fits in int.
21252 * menu.c (grow_menu_items): Check for int overflow.
21254 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21256 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21257 Before, the code was not consistent. These values cannot exceed
21258 2**31 - 1 so there's no need to make them unsigned.
21259 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21260 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21261 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21263 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21265 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21266 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21267 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21268 presumably because the widths might not match.
21270 * window.c (size_window): Avoid needless test at loop start.
21272 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21274 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21276 2011-05-12 Drew Adams <drew.adams@oracle.com>
21278 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21280 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21282 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21283 `width' to `bar_area_x' and `bar_area_width', respectively.
21284 (x_scroll_run): Take account of fringe background extension.
21286 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21287 Rename local vars `left' and `width' to `bar_area_x' and
21288 `bar_area_width', respectively.
21289 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21290 background extension.
21292 2011-05-10 Jim Meyering <meyering@redhat.com>
21294 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21296 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21298 * image.c (Finit_image_library): Return t for built-in image types,
21299 like pbm and xbm. (Bug#8640)
21301 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21303 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21305 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21307 * w32console.c (Fset_screen_color): Doc fix.
21308 (Fget_screen_color): New function.
21309 (syms_of_ntterm): Defsubr it.
21311 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21312 unlink the temporary file if Fcall_process didn't create it in the
21314 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21315 child process will be redirected to a file specified with `:file'.
21316 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21317 cue to call_process_cleanup not to close that handle.
21319 2011-05-07 Ben Key <bkey76@gmail.com>
21321 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21322 one of two shell specific rules, either bootstrap-temacs-CMD or
21323 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21324 to the previous implementation of the bootstrap-temacs rule.
21325 The bootstrap-temacs-CMD rule is similar to the previous
21326 implementation of the bootstrap-temacs rule except that it
21327 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21330 These changes, along with some changes to nt/configure.bat,
21331 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21332 earlier fix to add support for --cflags and --ldflags options
21333 that include quotes so that it works whether make uses cmd or
21336 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21338 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21339 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21341 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21342 a string. Handle both cases.
21343 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21344 (Fdbus_register_method): Use Qinvalid_function.
21346 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21348 * makefile.w32-in: Update dependencies.
21349 (LISP_H): Add inttypes.h and stdin.h.
21350 (PROCESS_H): Add unistd.h.
21352 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21354 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21355 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21357 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21359 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21361 * term.c (vfatal): Remove stray call to va_end.
21362 It's not needed and the C Standard doesn't allow it here anyway.
21364 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21365 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21367 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21370 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21372 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21374 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21376 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21378 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21380 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21381 * charset.c (Fdefine_charset_internal): Don't initialize
21382 charset.code_space[15]. The value was garbage, on hosts with
21383 32-bit int (Bug#8600).
21385 * lread.c (read_integer): Be more consistent with string-to-number.
21386 Use string_to_number to do the actual conversion; this avoids
21387 rounding errors and fixes some other screwups. Without this fix,
21388 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21389 (digit_to_number): Move earlier, for benefit of read_integer.
21390 Return -1 if the digit is out of range for the base, -2 if it is
21391 not a digit in any supported base. (Bug#8602)
21393 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21395 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21396 to match comment at start of function. This also removes a
21397 GCC warning about overflow in a 32+64-bit port.
21399 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21401 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21402 Reported by Stefan Monnier in
21403 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21404 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21405 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21407 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21408 (EMACS_UINTPTR): Likewise, with uintptr_t.
21410 * lisp.h: Prefer 64-bit EMACS_INT if available.
21411 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21412 on 32-bit hosts that have 64-bit int, so that they can access
21414 However, temporarily disable this change unless the temporary
21415 symbol WIDE_EMACS_INT is defined.
21417 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21419 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21420 This removes an assumption that EMACS_INT and long are the same
21421 width as pointers. The assumption is true for Emacs porting targets
21422 now, but we want to make other targets possible.
21423 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21424 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21425 In the rest of the code, change types of integers that hold casted
21426 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21427 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21428 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21429 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21430 No need to cast type when ORing.
21431 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21432 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21433 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21434 assume EMACS_INT is the same width as char *.
21435 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21436 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21437 Remove no-longer-needed casts.
21438 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21439 (xg_tool_bar_help_callback, xg_make_tool_item):
21440 Use EMACS_INTPTR to hold an integer
21441 that will be cast to void *; this can avoid a GCC warning
21442 if EMACS_INT is not the same width as void *.
21443 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21444 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21445 (current_message_1, set_message_1):
21446 Use a local to convert to proper width without a cast.
21447 * xmenu.c (dialog_selection_callback): Likewise.
21449 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21450 Also, don't assume VALBITS / RAND_BITS is less than 5,
21451 and don't rely on undefined behavior when shifting a 1 left into
21453 * lisp.h (get_random): Change signature to match.
21455 * lread.c (hash_string): Use size_t, not int, for hash computation.
21456 Normally we prefer signed values; but hashing is special, because
21457 it's better to use unsigned division on hash table sizes so that
21458 the remainder is nonnegative. Also, size_t is the natural width
21459 for hashing into memory. The previous code used 'int', which doesn't
21460 retain enough info to hash well into very large tables.
21461 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21463 * dbusbind.c: Don't possibly lose pointer info when converting.
21464 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21465 Use XPNTR rather than XHASH, so that the high-order bits of
21466 the pointer aren't lost when converting through void *.
21468 * eval.c (Fautoload): Don't double-shift a pointer.
21470 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21472 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21474 * gnutls.c (DEF_GNUTLS_FN):
21475 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21477 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21479 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21482 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21484 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21485 New version that can reserve upto 2GB of heap space.
21487 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21489 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21491 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21493 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21494 `gnutls_certificate_set_x509_key_file'.
21496 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21498 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21499 Update dependencies.
21501 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21503 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21504 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21505 Remove unused parameter `fildes'.
21506 * process.c (read_process_output, send_process): Don't pass it.
21508 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21510 Fix previous change: the library cache is defined in w32.c.
21511 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21512 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21514 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21516 Implement dynamic loading of GnuTLS on Windows.
21518 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21519 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21520 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21523 * gnutls.c (Qgnutls_dll): Define.
21524 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21525 (gnutls_*): Declare function pointers.
21526 (init_gnutls_functions): New function to initialize function pointers.

21528 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21529 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21530 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21531 (emacs_gnutls_write, emacs_gnutls_read)
21532 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21533 (Fgnutls_available_p): New function.
21534 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21535 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21536 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

21542 (w32_delayed_load): Move to w32.c.
21544 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21546 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21547 (w32_delayed_load): Move from image.c. When loading a library, record
21548 its filename in the :loaded-from property of the library id.
21549 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21550 Initialize and staticpro them.
21551 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21553 * process.c: Include lisp.h before w32.h, not after.
21554 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21555 instead of gnutls_record_check_pending.
21557 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21559 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21561 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21562 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21565 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21567 * xterm.c (x_set_frame_alpha): Do not set property on anything
21568 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21570 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21572 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21574 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21576 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

21590 * sysdep.c (wait_for_termination_1): Make static.
21591 (wait_for_termination, interruptible_wait_for_termination):
21592 Move after wait_for_termination_1.
21594 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21596 * sysdep.c (interruptible_wait_for_termination): New function
21597 which is like wait_for_termination, but allows keyboard
21600 * callproc.c (Fcall_process): Add (:file "file") as an option for
21602 (Fcall_process_region): Ditto.
21604 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21606 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21607 rather than `XVECTOR (FOO)->size'.
21609 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21610 inttypes.h, as a gnulib replacement is used if it not available in
21613 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21615 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21616 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21617 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21619 * coding.c (coding_alloc_by_realloc): Error out if destination
21620 will grow beyond MOST_POSITIVE_FIXNUM.
21621 (decode_coding_emacs_mule): Abort if there isn't enough place in
21622 charbuf for the composition carryover bytes. Reserve an extra

21630 aborting when %lld or %lll format is passed.
21631 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21632 %llo or %llx format is passed. (Bug#8545)
21634 * window.c (window_scroll_line_based): Use a marker instead of
21635 simple variables to record original value of point. (Bug#7952)
21637 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21638 produced by %s or %c overflows available buffer space. (Bug#8545)
21640 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21642 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21643 (SIZE_MAX): Move defn after all includes, as they might #define it.
21645 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21647 * w32.c (init_environment): Warn about defaulting HOME to C:\.

21657 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21659 * doprnt.c (doprnt): Don't return value smaller than the buffer
21660 size if the message was truncated. (Bug#8545).
21662 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21664 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

21667 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21669 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21671 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21673 * makefile.w32-in: Update dependencies.
21675 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21677 Improve `doprnt' and its usage. (Bug#8545)
21678 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21679 `format_end'. Remove support for %l as a conversion specifier.
21680 Don't use xrealloc. Improve diagnostics when the %l size modifier
21681 is used. Update the commentary.
21683 * eval.c (verror): Simplify calculation of size_t.
21685 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21688 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21690 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21693 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21695 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21696 This makes this file independent of the recent pseudovector change.
21698 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21700 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21702 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21703 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21704 Remove unused local.
21705 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21707 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21708 GCC 4.6.0 optimizes based on type-based alias analysis.
21709 For example, if b is of type struct buffer * and v of type struct
21710 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21711 != &v->size, and therefore "v->size = 1; b->size = 2; return
21712 v->size;" must therefore return 1. This assumption is incorrect
21713 for Emacs, since it type-puns struct Lisp_Vector * with many other
21714 types. To fix this problem, this patch adds a new type struct
21715 vectorlike_header that documents the constraints on layout of vectors
21716 and pseudovectors, and helps optimizing compilers not get fooled
21717 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21718 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21719 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21721 (XSETPVECTYPE): Rewrite in terms of new macro.
21722 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21723 This is a bit clearer, and further avoids the possibility of
21724 undesirable aliasing.
21725 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21726 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21727 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21728 since Lisp_Subr is a special case (no "next" field).
21729 (ASIZE): Now uses header.size rather than size.
21730 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21731 to avoid the hassle of writing XVECTOR (foo)->header.size.
21732 (struct vectorlike_header): New type.
21733 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21734 object, to help avoid aliasing.
21735 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21736 (SUBRP): Likewise, since Lisp_Subr is a special case.
21737 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21738 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21739 (struct Lisp_Hash_Table): Combine first two members into a single
21740 struct vectorlike_header member. All uses of "size" and "next" members
21741 changed to be "header.size" and "header.next".
21742 * buffer.h (struct buffer): Likewise.
21743 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21744 * frame.h (struct frame): Likewise.
21745 * process.h (struct Lisp_Process): Likewise.
21746 * termhooks.h (struct terminal): Likewise.
21747 * window.c (struct save_window_data, struct saved_window): Likewise.
21748 * window.h (struct window): Likewise.
21749 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21750 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21751 * buffer.c (init_buffer_once): Likewise.
21752 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21754 * process.c (Fformat_network_address): Use local var for size,
21757 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21759 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21760 * data.c (atof): Remove decl; no longer used or needed.
21761 (digit_to_number): Move to lread.c.
21762 (Fstring_to_number): Use new string_to_number function, to be
21763 consistent with how the Lisp reader treats infinities and NaNs.
21764 Do not assume that floating-point numbers represent EMACS_INT
21765 without losing information; this is not true on most 64-bit hosts.
21766 Avoid double-rounding errors, by insisting on integers when
21767 parsing non-base-10 numbers, as the documentation specifies.
21768 * lisp.h (string_to_number): New decl, replacing ...
21769 (isfloat_string): Remove.
21770 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21771 (read1): Do not accept +. and -. as integers; this
21772 appears to have been a coding error. Similarly, do not accept
21773 strings like +-1e0 as floating point numbers. Do not report
21774 overflow for integer overflows unless the base is not 10 which
21775 means we have no simple and reliable way to continue.
21776 Break out the floating-point parsing into a new
21777 function string_to_number, so that Fstring_to_number parses
21778 floating point numbers consistently with the Lisp reader.
21779 (digit_to_number): Move here from data.c. Make it static inline.
21780 (E_CHAR, EXP_INT): Remove, replacing with ...
21781 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21782 (string_to_number): New function, replacing isfloat_string.
21783 This function checks for valid syntax and produces the resulting
21784 Lisp float number too. Rework it so that string-to-number
21785 no longer mishandles examples like "1.0e+". Use strtoumax,
21786 so that overflow for non-base-10 numbers is reported only when
21787 there's no portable and simple way to convert to floating point.
21789 * textprop.c (set_text_properties_1): Rewrite for clarity,
21790 and to avoid GCC warning about integer overflow.
21792 * intervals.h (struct interval): Use EMACS_INT for members
21793 where EMACS_UINT might cause problems. See
21794 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21795 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21796 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21798 (offset_intervals): Tell GCC not to worry about length overflow
21799 when negating a negative length.
21801 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21802 (overrun_check_free): Likewise.
21804 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21805 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21808 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21809 (gnutls_make_error): Rename local to avoid shadowing.
21810 (gnutls_emacs_global_deinit): ifdef out; not used.
21811 (Fgnutls_boot): Use const for pointer to readonly storage.
21812 Comment out unused local. Fix pointer signedness problems.
21814 * lread.c (openp): Don't stuff size_t into an 'int'.
21815 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21816 about possible signed overflow.
21818 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21819 (GDK_KEY_g): Don't define if already defined.
21820 (xg_prepare_tooltip): Avoid pointer signedness problem.
21821 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21823 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21824 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21826 * xfns.c (Fx_window_property): Simplify a bit,
21827 to make a bit faster and to avoid GCC 4.6.0 warning.
21828 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21830 * fns.c (internal_equal): Don't assume size_t fits in int.
21832 * alloc.c (compact_small_strings): Tighten assertion a little.
21834 Replace pEd with more-general pI, and fix some printf arg casts.
21835 * lisp.h (pI): New macro, generalizing old pEd macro to other
21836 conversion specifiers. For example, use "...%"pI"d..." rather
21837 than "...%"pEd"...".
21838 (pEd): Remove. All uses replaced with similar uses of pI.
21839 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21840 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21841 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21842 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21843 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21844 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21845 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21847 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21848 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21849 * print.c (safe_debug_print, print_object): Likewise.
21850 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21852 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21853 avoiding the 0 flag, which is not portable.
21854 * process.c (Fmake_network_process): Use pI to avoid cast.
21855 * region-cache.c (pp_cache): Likewise.
21856 * xdisp.c (decode_mode_spec): Likewise.
21857 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21858 behavior on 64-bit hosts with printf arg.
21859 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21860 (x_stop_queuing_selection_requests): Likewise.
21861 (x_get_window_property): Don't truncate byte count to an 'int'
21864 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21865 here, since it parses constructs like leading '-' and spaces,
21866 which are not wanted; and it overflows with large numbers.
21867 Instead, simply match F[0-9]+, which is what is wanted anyway.
21869 * alloc.c: Remove unportable assumptions about struct layout.
21870 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21871 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21872 (allocate_vectorlike, make_pure_vector): Use the new macros,
21873 plus offsetof, to remove unportable assumptions about struct layout.
21874 These assumptions hold on all porting targets that I know of, but
21875 they are not guaranteed, they're easy to remove, and removing them
21876 makes further changes easier.
21878 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21879 This doesn't fix a bug but makes the code clearer.
21880 (string_overrun_cookie): Now const. Use initializers that
21881 don't formally overflow signed char, to avoid warnings.
21882 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21883 can cause Emacs to crash when string overrun checking is enabled.
21884 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21885 multiple of sizeof (EMACS_INT); it need not be, if
21886 alignof(EMACS_INT) < sizeof (EMACS_INT).
21887 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21889 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21896 supposed to be handshaking. (Bug#8556)
21897 Reported by Paul Eggert <eggert@cs.ucla.edu>.

21910 (check_string_free_list): Convert to standard C.
21912 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21914 * w32.c (emacs_gnutls_push): Fix typo.
21916 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21918 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21919 "cast to pointer from integer of different size".
21921 Improve doprnt and its use in verror. (Bug#8545)
21922 * doprnt.c (doprnt): Document the set of format control sequences
21923 supported by the function. Use SAFE_ALLOCA instead of always
21926 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21927 is one byte too soon. Don't use xrealloc; instead xfree and
21930 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21932 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21935 * gnutls.c: Renamed global_initialized to
21936 gnutls_global_initialized. Added internals for the
21937 :verify-hostname-error, :verify-error, and :verify-flags
21938 parameters of `gnutls-boot' and documented those parameters in the
21939 docstring. Start callback support.
21940 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21941 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21942 on error. Return error code.

22002 changes in globals.h immediately force recompilation.
22003 (TAGS): Depend on $(CURDIR)/m/intel386.h and
22004 $(CURDIR)/s/ms-w32.h.

22014 * doprnt.c: Include limits.h.
22015 (SIZE_MAX): New macro.
22016 (doprnt): Return a size_t value. 2nd arg is now size_t.
22017 Many local variables are now size_t instead of int or unsigned.
22018 Improve overflow protection. Support `l' modifier for integer
22019 conversions. Support %l conversion. Don't assume an EMACS_INT
22020 argument for integer conversions and for %c.
22022 * lisp.h (doprnt): Restore prototype.
22024 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22025 $(SRC)/character.h.
22027 * Makefile.in (base_obj): Add back doprnt.o.
22029 * deps.mk (doprnt.o): Add back prerequisites.
22030 (callint.o): Depend on character.h.
22032 * eval.c (internal_lisp_condition_case): Include the handler
22033 representation in the error message.

22039 * callint.c (Fcall_interactively): When displaying error message
22040 about invalid control letter, pass the character's codepoint, not
22041 a pointer to its multibyte form. Improve display of the character
22042 in octal and display also its hex code.
22044 * character.c (char_string): Use %x to display the (unsigned)
22045 codepoint of an invalid character, to avoid displaying a bogus
22048 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
22049 `error', not SYMBOL_NAME itself.
22051 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
22052 character arguments to `error'.
22054 * charset.c (check_iso_charset_parameter): Fix incorrect argument
22055 to `error' in error message about FINAL_CHAR argument. Make sure
22056 FINAL_CHAR is a character, and use %c when it is passed as
22057 argument to `error'.

22121 Define only if needed.
22123 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
22124 by pacifying GCC about it. Maybe it's time to retire it?
22125 * xfaces.c (USG, __TIMEVAL__): Likewise.
22127 * dispextern.h (struct redisplay_interface): Rename param
22128 to avoid shadowing.
22129 * termhooks.h (struct terminal): Likewise.
22130 * xterm.c (xembed_send_message): Likewise.
22132 * insdel.c (make_gap_smaller): Define only if
22133 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
22135 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
22138 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
22139 so that we aren't warned about unused symbols.
22141 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
22143 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
22145 * xfns.c (x_real_positions): Mark locals as initialized.
22147 * xmenu.c (xmenu_show): Don't use uninitialized vars.

22150 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
22151 (x_dispatch_event): Declare static if USE_GTK, and
22152 define if USE_GTK || USE_X_TOOLKIT.
22153 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
22154 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

22156 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
22158 * xmenu.c (menu_help_callback): Pointer type fixes.
22159 Use const pointers when pointing at readonly data. Avoid pointer

22175 * bitmaps: Change bitmaps from unsigned char back to the X11
22176 compatible char. Avoid the old compiler warnings about
22177 out-of-range initializers by using, for example, '\xab' rather
22180 * xgselect.c (xgselect_initialize): Check vs interface

22246 * nsfont.m: Fixed bugs in ns_get_family and
22247 ns_descriptor_to_entity that were caused by using free to

22250 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
22251 --enable-checking=xmallocoverrun). xfree is now used to
22252 deallocate these memory blocks.

22618 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22620 alloc.c: Import and export fewer symbols, and remove unused items.
22621 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22623 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22624 it's not optimized away by whole-program optimization.
22625 (message_enable_multibyte, free_misc): Remove.
22626 (catchlist, handlerlist, mark_backtrace):
22627 Declare only if BYTE_MARK_STACK.
22628 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
22629 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
22630 (message_enable_multibyte): Remove decl.
22631 (free_misc, interval_free_list, float_block, float_block_index):
22632 (n_float_blocks, float_free_list, cons_block, cons_block_index):
22633 (cons_free_list, last_marked_index):
22635 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
22636 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22637 (mark_backtrace): Define only if BYTE_MARK_STACK.
22638 * xdisp.c (message_enable_multibyte): Now static.
22640 Declare Lisp_Object Q* variables to be 'static' if not exported.
22641 This makes it easier for human readers (and static analyzers)
22642 to see whether these variables are used from other modules.
22643 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22644 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
22645 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
22646 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
22647 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
22648 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
22649 * xmenu.c, xselect.c:
22650 Declare Q* vars static if they are not used in other modules.
22651 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
22652 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
22653 Remove decls of unexported vars.
22654 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22656 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22658 Make Emacs functions such as Fatom 'static' by default.
22659 This makes it easier for human readers (and static analyzers)
22660 to see whether these functions can be called from other modules.
22661 DEFUN now defines a static function. To make the function external
22662 so that it can be used in other C modules, use the new macro DEFUE.
22663 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22664 (Finit_image_library):
22665 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22666 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22667 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22668 Remove decls, since these functions are now static.
22669 (Funintern, Fget_internal_run_time): New decls, since these functions
22670 were already external.
22672 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22673 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
22674 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
22675 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
22676 * keyboard.c, keymap.c, lread.c:
22677 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
22678 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
22679 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22680 Mark functions with DEFUE instead of DEFUN,
22681 if they are used in other modules.
22682 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22683 decls for now-static functions.
22684 * buffer.h (Fdelete_overlay): Remove decl.
22685 * callproc.c (Fgetenv_internal): Mark as internal.
22686 * composite.c (Fremove_list_of_text_properties): Remove decl.

22690 * doc.c (Fdocumntation_property): New forward static decl.
22691 * eval.c (Ffetch_bytecode): New forward static decl.
22692 (Funintern): Remove extern decl; now in .h file where it belongs.
22693 * fileio.c (Fmake_symbolic_link): New forward static decl.
22694 * image.c (Finit_image_library): New forward static decl.
22695 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22696 * intervals.h (Fprevious_property_change):
22697 (Fremove_list_of_text_properties): Remove decls.
22698 * keyboard.c (Fthis_command_keys): Remove decl.
22699 (Fcommand_execute): New forward static decl.
22700 * keymap.c (Flookup_key): New forward static decl.
22701 (Fcopy_keymap): Now static.
22702 * keymap.h (Flookup_key): Remove decl.
22703 * process.c (Fget_process): New forward static decl.
22704 (Fprocess_datagram_address): Mark as internal.

22715 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22717 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22720 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22722 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22723 when at ZV. (Bug#8487)
22725 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22727 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22729 * keyboard.c (parse_tool_bar_item): Likewise.
22730 * sound.c (sound_cleanup, alsa_close): Likewise.
22731 * termcap.c (tgetent): Likewise.
22732 * xfns.c (x_default_font_parameter): Likewise.
22733 * xsettings.c (read_and_apply_settings): Likewise.
22735 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22736 (overrun_check_free): Protoize.
22738 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22740 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22741 since callers should never pass a negative size.
22742 Change the signature to match that of plain 'read' and 'write'; see
22743 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22744 * lisp.h: Update prototypes of emacs_write and emacs_read.
22746 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22748 * xdisp.c (redisplay_window): Don't try to determine the character
22749 position of the scroll margin if the window start point w->startp
22750 is outside the buffer's accessible region. (Bug#8468)
22752 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22754 Fix write-region and its subroutines for buffers > 2GB.
22755 * fileio.c (a_write, e_write): Modify declaration of arguments and
22756 local variables to support buffers larger than 2GB.
22757 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22759 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22760 argument, local variables, and return value.
22762 * lisp.h: Update prototypes of emacs_write and emacs_read.
22764 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22766 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22768 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22770 Fix more problems found by GCC 4.6.0's static checks.
22772 * xdisp.c (vmessage): Use a better test for character truncation.
22774 * charset.c (load_charset_map): <, not <=, for optimization,
22775 and to avoid potential problems with integer overflow.
22776 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22777 * casetab.c (set_identity, shuffle): Likewise.
22778 * editfns.c (Fformat): Likewise.
22779 * syntax.c (skip_chars): Likewise.
22781 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22782 This also lets GCC 4.6.0 generate slightly better loop code.
22784 * callint.c (Fcall_interactively): <, not <=, for optimization.
22785 (Fcall_interactively): Count the number of arguments produced,
22786 not the number of arguments given. This is simpler and lets GCC
22787 4.6.0 generate slightly better code.
22789 * ftfont.c: Distingish more carefully between FcChar8 and char.
22790 The previous code passed unsigned char * to a functions like
22791 strlen and xstrcasecmp that expect char *, which does not
22792 conform to the C standard.
22793 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22794 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22795 char * when the C standard requires it.
22797 * keyboard.c (read_char): Remove unused var.
22799 * eval.c: Port to Windows vsnprintf (Bug#8435).
22800 Include <limits.h>.
22801 (SIZE_MAX): Define if the headers do not.
22802 (verror): Do not give up if vsnprintf returns a negative count.
22803 Instead, grow the buffer. This ports to Windows vsnprintf, which
22804 does not conform to C99. Problem reported by Eli Zaretskii.
22805 Also, simplify the allocation scheme, by avoiding the need for
22806 calling realloc, and removing the ALLOCATED variable.
22808 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22810 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22811 But keep the doprint source code for now, as we might revamp it
22812 and use it again (Bug#8435).
22813 * lisp.h (doprnt): Remove.
22814 * Makefile.in (base_obj): Remove doprnt.o.
22815 * deps.mk (doprnt.o): Remove.
22817 error: Print 32- and 64-bit integers portably (Bug#8435).
22818 Without this change, on typical 64-bit hosts error ("...%d...", N)
22819 was used to print both 32- and 64-bit integers N, which relied on
22820 undefined behavior.
22821 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22822 * lisp.h (error, verror): Mark as printf-like functions.
22823 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22824 Report overflow in size calculations when allocating printf buffer.
22825 Do not truncate output string at its first null byte.
22826 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22827 Truncate the output at a character boundary, since vsnprintf does not
22829 * charset.c (check_iso_charset_parameter): Convert internal
22830 character to string before calling 'error', since %c now has the
22832 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22833 overflow when computing char to be passed to 'error'. Do not
22834 pass Lisp_Object to 'error'; pass the integer instead.
22835 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22836 formatted with plain %d.
22838 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22840 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22842 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22844 * xterm.c (x_catch_errors): Remove duplicate declaration.
22846 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22848 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22850 2011-04-10 Jim Meyering <meyering@redhat.com>
22852 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22853 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22854 return ssize_t not "int", and use size_t as the buffer length.
22855 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22856 * gnutls.h: Update declarations.
22857 * process.c (read_process_output): Use ssize_t, to match.
22858 (send_process): Likewise.
22860 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22862 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22864 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22866 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22867 Use unsigned char, to match FcChar8 type definition.
22869 * xterm.c (handle_one_xevent):
22870 * xmenu.c (create_and_show_popup_menu):
22871 * xselect.c (x_decline_selection_request)
22872 (x_reply_selection_request): Avoid type-punned deref of X events.
22874 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22876 Fix some uses of `int' instead of EMACS_INT.
22877 * search.c (string_match_1, fast_string_match)
22878 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22879 (scan_buffer, find_next_newline_no_quit)
22880 (find_before_next_newline, search_command, Freplace_match)
22881 (Fmatch_data): Make some `int' variables be EMACS_INT.
22883 * xdisp.c (display_count_lines): 3rd argument and return value now
22884 EMACS_INT. All callers changed.
22885 (pint2hrstr): Last argument is now EMACS_INT.
22887 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22888 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22889 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22890 (decode_coding_utf_16, decode_coding_emacs_mule)
22891 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22892 (decode_coding_ccl, decode_coding_charset)
22893 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22894 (decode_coding_iso_2022, decode_coding_emacs_mule)
22895 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22896 <char_offset, last_offset>: Declare EMACS_INT.
22897 (encode_coding_utf_8, encode_coding_utf_16)
22898 (encode_coding_emacs_mule, encode_invocation_designation)
22899 (encode_designation_at_bol, encode_coding_iso_2022)
22900 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22901 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22903 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22904 (encode_invocation_designation): Last argument P_NCHARS is now
22906 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22907 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22909 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22912 * ccl.c (Fccl_execute_on_string): Declare some variables
22915 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22917 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22919 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22921 * process.c (Fformat_network_address): Doc fix.
22923 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22925 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22927 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22929 * keyboard.c (read_char): Call Lisp function help-form-show,
22930 instead of using internal_with_output_to_temp_buffer.
22931 (Qhelp_form_show): New var.
22932 (syms_of_keyboard): Use DEFSYM macro.
22934 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22936 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22938 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22940 * process.c (Flist_processes): Remove to Lisp.
22941 (list_processes_1): Delete.
22943 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22945 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22947 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22949 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22951 Fix more problems found by GCC 4.6.0's static checks.
22953 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22955 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22957 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22959 * xdisp.c (vmessage): Mark as a printf-like function.
22961 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22963 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22965 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22966 printf-like functions.
22967 (tiff_load): Add casts to remove these marks before passing them
22968 to system-supplied API.
22970 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22972 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22973 This avoids several warnings with gcc -Wstrict-overflow.
22974 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22975 directly, rather than having caller test rule sign. This avoids
22976 some unnecessary tests.
22977 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22978 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22979 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22981 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22982 (xfont_open): Avoid unnecessary tests.
22984 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22986 * composite.h, composite.c (composition_gstring_put_cache):
22987 Use EMACS_INT, not int, for length.
22989 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22990 breaking out part of COMPOSITION_DECODE_RULE.
22991 (COMPOSITION_DECODE_RULE): Use it.
22992 * composite.c (get_composition_id): Remove unused local vars,
22993 by using the new macro.
22995 * textprop.c (set_text_properties_1): Change while to do-while,
22996 since the condition is always true at first.
22998 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22999 (interval_deletion_adjustment): Return unsigned value.
23002 * process.c (list_processes_1, create_pty, read_process_output):
23003 (exec_sentinel): Remove vars that were set but not used.
23004 (create_pty): Remove unnecessary "volatile"s.
23005 (Fnetwork_interface_info): Avoid possibility of int overflow.
23006 (read_process_output): Do adaptive read buffering even if carryover.
23007 (read_process_output): Simplify nbytes computation if buffered.
23009 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
23011 * syntax.c (scan_words): Remove var that was set but not used.
23012 (update_syntax_table): Use unsigned instead of int.
23014 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
23015 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
23016 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
23018 * print.c (print_error_message): Avoid int overflow.
23020 * font.c (font_list_entities): Redo for clarity,
23021 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23023 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23024 (font_score): Avoid potential overflow in diff calculation.
23026 * fns.c (substring_both): Remove var that is set but not used.
23027 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23029 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23031 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23032 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23033 can always succeed if overflow has undefined behavior.
23035 * search.c (boyer_moore, wordify): Remove vars set but not used.
23036 (wordify): Omit three unnecessary tests.
23038 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23039 All callers changed. This avoids the need for an unused var.
23041 * casefiddle.c (casify_region): Remove var that is set but not used.
23043 * dired.c (file_name_completion): Remove var that is set but not used.
23045 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23047 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23048 (Finsert_file_contents): Remove unnecessary code checking fd.
23050 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23051 Check for integer overflow on size calculations.
23053 * buffer.c (Fprevious_overlay_change): Remove var that is set
23056 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23057 Remove vars that are set but not used.
23058 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23059 (timer_check_2): Mark vars as initialized.
23061 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23063 * image.c (lookup_image): Remove var that is set but not used.
23064 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23066 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23067 that are set but not used.
23069 * xfns.c (make_invisible_cursor): Don't return garbage
23070 if XCreateBitmapFromData fails (Bug#8410).
23072 * xselect.c (x_get_local_selection, x_handle_property_notify):
23073 Remove vars that are set but not used.
23075 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

23081 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23082 Check for overflow.
23084 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23085 (map_tty_color) [!defined MSDOS]: Likewise.
23087 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23089 * coding.c: Remove vars that are set but not used.
23090 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

23099 * print.c (print_object): Remove var that is set but not used.
23101 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23102 The gnulib version avoids calling malloc in the usual case,
23103 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23104 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23105 * filelock.c (current_lock_owner): Likewise.
23106 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23107 * sysdep.c: Include allocator.h, careadlinkat.h.
23108 (emacs_no_realloc_allocator): New static constant.
23109 (emacs_readlink): New function.
23110 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23111 ../lib/careadlinkat.h.
23113 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23115 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

23137 do not dereference NULL upon failed strdup
23138 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23139 (ns_get_family): Likewise.
23141 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23143 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23145 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23147 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23150 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23152 Add lexical binding.
23154 * window.c (Ftemp_output_buffer_show): New fun.

23163 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23165 (syms_of_lread): Declare `lexical-binding'.
23167 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23169 * keyboard.c (eval_dyn): New fun.
23170 (menu_item_eval_property): Use it.
23172 * image.c (parse_image_spec): Use Ffunctionp.
23174 * fns.c (concat, mapcar1): Accept byte-code-functions.
23176 * eval.c (Fsetq): Handle lexical vars.
23177 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23178 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23179 (FletX, Flet): Obey lexical binding.
23180 (Fcommandp): Handle closures.
23181 (Feval): New `lexical' arg.
23182 (eval_sub): New function extracted from Feval. Use it almost
23183 everywhere where Feval was used. Look up vars in lexical env.
23185 (Ffunctionp): Move from subr.el.
23186 (Ffuncall): Handle closures.
23187 (apply_lambda): Remove `eval_flags'.
23188 (funcall_lambda): Handle closures and new byte-code-functions.
23189 (Fspecial_variable_p): New function.
23190 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23191 but without exporting it to Lisp.
23193 * doc.c (Fdocumentation, store_function_docstring):
23194 * data.c (Finteractive_form): Handle closures.
23196 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23199 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23201 (exec_byte_code): New function extracted from Fbyte_code to handle new
23202 calling convention for byte-code-functions. Add new byte-codes.
23204 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

23210 * xdisp.c (redisplay_internal): Fix prototype.
23212 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23214 * xdisp.c (SCROLL_LIMIT): New macro.
23215 (try_scrolling): Use it when setting scroll_limit.
23216 Limit scrolling to 100 screen lines.
23217 (redisplay_window): Even when falling back on "recentering",
23218 position point in the window according to scroll-conservatively,
23219 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23221 (try_scrolling): When point is above the window, allow searching
23222 as far as scroll_max, or one screenful, to compute vertical
23223 distance from PT to the scroll margin position. This prevents
23224 try_scrolling from unnecessarily failing when
23225 scroll-conservatively is set to a value slightly larger than the
23226 window height. Clean up the case of PT below the margin at bottom
23227 of window: scroll_max can no longer be INT_MAX. When aggressive
23228 scrolling is in use, don't let point enter the opposite scroll
23229 margin as result of the scroll.
23230 (syms_of_xdisp) <scroll-conservatively>: Document the
23231 threshold of 100 lines for never-recentering scrolling.

23238 (message_log_check_duplicate): Remove parameters `prev_bol' and
23239 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23240 (redisplay_internal): Remove parameter `preserve_echo_area',
23241 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23243 * indent.c (Fvertical_motion):
23244 * window.c (window_scroll_pixel_based, Frecenter):
23245 Don't pass `need_y_p' to `move_it_by_lines'.
23247 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23249 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23250 steal a few bits to be more compact.
23251 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23252 Remove unneeded casts.
23254 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23256 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23258 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23259 binding" message (bug#7967).
23261 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23263 Fix more problems found by GCC 4.6.0's static checks.
23265 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23266 Remove unused local var.
23268 * editfns.c (Fmessage_box): Remove unused local var.
23270 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23271 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23272 Omit unused local vars.
23273 * window.c (shrink_windows): Omit unused local var.
23274 * menu.c (digest_single_submenu): Omit unused local var.
23275 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23276 Omit unused local var.
23278 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23279 Don't assume string length fits in int.
23280 (keyremap_step, read_key_sequence): Use size_t for sizes.

23284 instead of alloca (Bug#8344).
23286 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23287 (Fbacktrace_frame): Don't assume nframes fits in int.
23289 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

23296 * cm.c (calccost): Turn while-do into do-while, for clarity.
23298 * keyboard.c (syms_of_keyboard): Use the same style as later
23299 in this function when indexing through an array. This also
23300 works around GCC bug 48267.
23302 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23304 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23306 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23307 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23309 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23310 This avoids undefined behavior on integer overflow, and is a bit
23311 more convenient anyway since it is compared to a size_t variable.
23313 Variadic C functions now count arguments with size_t, not int.
23314 This avoids an unnecessary limitation on 64-bit machines, which
23315 caused (substring ...) to crash on large vectors (Bug#8344).

23325 * fns.c (concat): Likewise.
23326 * frame.c (x_set_frame_parameters): Likewise.
23327 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23328 0 if not found, not -1. All callers changed.
23330 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23331 (stack_copy_size): Now size_t, not int.
23332 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

23353 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23354 don't set the hook to nil, but remove the offending function instead.

23356 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23357 Vcommand_hook_internal.

23496 Remove unused variable `width'.
23498 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
23500 * w32term.c (x_set_glyph_string_clipping):
23501 Don't pass uninitialized region to CombineRgn.
23503 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
23505 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

23525 2011-03-23 Julien Danjou <julien@danjou.info>
23527 * term.c (Fsuspend_tty, Fresume_tty):
23528 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
23529 * window.c (temp_output_buffer_show):
23530 * insdel.c (signal_before_change):
23531 * frame.c (Fhandle_switch_frame):
23532 * fileio.c (Fdo_auto_save):

23535 * cmds.c (internal_self_insert):
23536 * callint.c (Fcall_interactively):
23537 * buffer.c (Fkill_all_local_variables):
23538 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23540 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23541 unconditionally since it does the check itself.
23543 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23545 Fix more problems found by GCC 4.5.2's static checks.
23547 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23548 the first time through the loop, since we know p0 < p1 then.
23549 This also avoids a gcc -Wstrict-overflow warning.
23551 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23552 leading to a memory leak, possible in functions like
23553 load_charset_map_from_file that can allocate an unbounded number
23554 of objects (Bug#8318).
23556 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23557 that could (at least in theory) be that large.
23559 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23560 This is less likely to overflow, and avoids undefined behavior if
23561 overflow does occur. All callers changed. Use strtoul to scan
23562 for the unsigned long integer.
23563 (pint2hrstr): Simplify and tune code slightly.
23564 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23566 * scroll.c (do_scrolling): Work around GCC bug 48228.
23567 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
23569 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
23570 This also avoids a warning with gcc -Wstrict-overflow.
23571 (validate_x_resource_name): Simplify count usage.
23572 This also avoids a warning with gcc -Wstrict-overflow.
23574 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23577 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23579 * process.c (Fmake_network_process): Use socklen_t, not int,
23580 where POSIX says socklen_t is required in portable programs.
23581 This fixes a porting bug on hosts like 64-bit HP-UX, where
23582 socklen_t is wider than int (Bug#8277).
23583 (Fmake_network_process, server_accept_connection):
23584 (wait_reading_process_output, read_process_output):
23587 * process.c: Rename or move locals to avoid shadowing.

23597 Make tparam.h and terminfo.c consistent.
23598 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23599 Include tparam.h instead, since it declares them.
23600 * cm.h (PC): Remove extern decl; tparam.h now does this.
23601 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23602 * terminfo.c: Include tparam.h, to check interfaces.
23603 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23604 (tparam): Adjust signature to match interface in tparam.h;
23605 this removes some undefined behavior. Check that outstring and len
23606 are zero, which they always are with Emacs.
23607 * tparam.h (PC, BC, UP): New extern decls.
23609 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23610 (xftfont_open): Rename locals to avoid shadowing.
23612 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
23613 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
23614 (OTF_TAG_SYM): Omit macro if not needed.

23622 * xml.c (make_dom): Now static.
23624 * composite.c (composition_compute_stop_pos): Rename local to
23626 (composition_reseat_it): Remove unused locals.
23627 (find_automatic_composition, composition_adjust_point): Likewise.
23628 (composition_update_it): Mark var as initialized.
23629 (find_automatic_composition): Mark vars as initialized,
23630 with a FIXME (Bug#8290).

23633 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23634 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23635 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23636 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23637 to avoid shadowing.
23639 * textprop.c (property_change_between_p): Remove; unused.
23641 * intervals.c (interval_start_pos): Now static.
23643 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23646 Rename locals to avoid shadowing.
23648 * sound.c (wav_play, au_play, Fplay_sound_internal):
23649 Fix pointer signedness.
23650 (alsa_choose_format): Remove unused local var.
23651 (wav_play): Initialize a variable to 0, to prevent undefined
23652 behavior (Bug#8278).
23654 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23656 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23658 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23659 clobbering (Bug#8298).
23660 * sysdep.c (sys_subshell): Likewise.
23661 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23663 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23664 This should get cleaned up, so that child_setup has the
23665 same signature on all platforms.
23667 * callproc.c (call_process_cleanup): Now static.
23668 (relocate_fd): Rename locals to avoid shadowing.
23670 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23672 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23673 not to be necessary, and produces flickering.
23675 2011-03-20 Glenn Morris <rgm@gnu.org>
23677 * config.in: Remove file.
23679 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23681 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23682 are now in src/globals.h.
23683 (syms_of_minibuf): Remove spurious & from previous change.
23685 2011-03-20 Leo Liu <sdl.web@gmail.com>
23687 * minibuf.c (completing-read-function): New variable.
23688 (completing-read-default): Rename from completing-read.
23689 (completing-read): Call completing-read-function.
23691 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23693 * xfaces.c (Fx_load_color_file):
23694 Read color file from absolute filename (bug#8250).
23696 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23698 * makefile.w32-in: Update dependencies.
23700 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23702 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23709 (sigchld_handler): Now static.
23711 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23712 That way, the code declares only the vars that it needs.
23713 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
23714 * s/cygwin.h (PTY_ITERATION): Likewise.
23715 * s/darwin.h (PTY_ITERATION): Likewise.

23721 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
23722 (CONSTANTLIM): Remove; unused.
23723 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23724 Define only if needed.
23726 * unexelf.c (unexec): Name an expression,
23727 to avoid gcc -Wbad-function-cast warning.
23728 Use a different way to cause a compilation error if anyone uses
23729 n rather than nn, a way that does not involve shadowing.
23730 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23732 * deps.mk (unexalpha.o): Remove; unused.
23734 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23735 * unexec.h: New file.
23736 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23737 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23738 Depend on unexec.h.
23739 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23740 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23741 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23742 Change as necessary to match prototype in unexec.h.
23744 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
23746 (back_comment, skip_chars): Mark vars as initialized.

23760 instead of using an uninitialized var.
23761 (font_sort_entities): Mark var as initialized.
23763 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
23765 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

23777 * floatfns.c (domain_error2): Define only if needed.
23778 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
23780 * alloc.c (mark_backtrace): Move decl from here ...

23789 * callint.c (quotify_arg, quotify_args): Now static.
23790 (Fcall_interactively): Rename locals to avoid shadowing.
23791 Use const pointer when appropriate.
23793 * lisp.h (get_system_name, get_operating_system_release):

23797 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23798 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23799 some of which prompt warnings from gcc -Wbad-function-cast.
23800 (Fformat_time_string, Fencode_time, Finsert_char):
23801 (Ftranslate_region_internal, Fformat):
23802 Rename or remove local vars to avoid shadowing.
23803 (Ftranslate_region_internal): Mark var as initialized.
23805 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23808 * lisp.h (eassert): Check that the argument compiles, even if
23809 ENABLE_CHECKING is not defined.
23811 * data.c (Findirect_variable): Name an expression, to avoid
23812 gcc -Wbad-function-cast warning.

23820 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
23821 Rename locals to avoid shadowing.
23822 (mark_stack): Move local variables into the #ifdef region where
23824 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23825 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23827 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23828 (GC_STRING_CHARS): Remove; not used.
23829 (Fmemory_limit): Cast sbrk's returned value to char *.
23831 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23832 avoids undefined behavior in theory.
23834 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23836 Use functions, not macros, for up- and down-casing (Bug#8254).
23837 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23838 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23839 to use the following functions instead of these macros.
23840 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23841 EMACS_INT, since callers assume the returned value fits in int.
23842 (upcase1): Likewise, for UPCASE_TABLE.
23843 (uppercasep, lowercasep, upcase): New static inline functions.
23844 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23845 the race-condition problem in the old DOWNCASE.
23847 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

23849 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
23850 (regex_compile, re_search_2, re_match_2_internal):
23851 Remove unused local vars.
23852 (FREE_VAR): Rewrite so as not to use empty "else",
23853 which gcc can warn about.
23854 (regex_compile, re_match_2_internal): Mark locals as initialized.
23855 (RETALLOC_IF): Define only if needed.
23856 (WORDCHAR_P): Likewise. This one is never needed, but is used
23857 only in a comment talking about a compiler bug, so put inside
23858 the #if 0 of that comment.
23859 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23860 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23863 * search.c (boyer_moore): Rename locals to avoid shadowing.
23864 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
23865 (PREV_CHAR_BOUNDARY): Likewise.
23867 * search.c (simple_search): Remove unused var.
23869 * dired.c (compile_pattern): Move decl from here ...

23877 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23878 Rename locals to avoid shadowing.
23879 (Fvertical_motion): Mark locals as initialized.
23881 * casefiddle.c (casify_object, casify_region): Now static.
23882 (casify_region): Mark local as initialized.
23884 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
23886 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23887 New macros, so that the caller can use some names other than
23888 gcpro1, gcpro2, etc.
23889 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23891 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23892 argument, for consistency with GCPRO2_VAR, etc: it is now the
23893 prefix of the variable, not the variable itself. All uses
23895 * dired.c (directory_files_internal, file_name_completion):
23896 Rename locals to avoid shadowing.
23898 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23899 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23900 dired.c's scmp function, had undefined behavior.
23901 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23902 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23903 * buffer.h: ... to here, because these macros use current_buffer,
23904 and the new implementation with inline functions needs to have
23905 current_buffer in scope now, rather than later when the macros
23907 (downcase, upcase1): New static inline functions.
23908 (DOWNCASE, UPCASE1): Reimplement using these functions.
23909 This avoids undefined behavior in expressions like
23910 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23911 from race conditions in accessing the global variables
23912 case_temp1 and case_temp2.
23913 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23914 * lisp.h (case_temp1, case_temp2): Remove their decls.
23915 * character.h (ASCII_CHAR_P): Move from here ...
23916 * lisp.h: ... to here, so that the inline functions mentioned
23917 above can use them.
23919 * dired.c (directory_files_internal_unwind): Now static.
23921 * fileio.c (file_name_as_directory, directory_file_name):
23922 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23924 (file_name_as_directory): Use const pointers when appropriate.
23925 (Fexpand_file_name): Likewise. In particular, newdir might
23926 point at constant storage, so make it a const pointer.
23927 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23928 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23930 (Fset_file_times, Finsert_file_contents, auto_save_error):
23931 Rename locals to avoid shadowing.
23933 * minibuf.c (choose_minibuf_frame_1): Now static.
23934 (Ftry_completion, Fall_completions): Rename or remove locals
23935 to avoid shadowing.
23937 * marker.c (bytepos_to_charpos): Remove; unused.

24361 is actually in tparam.c. The previous trick of using incompatible
24362 decls in different modules does not conform to the C standard.
24363 All callers of tparam changed to use tparam's actual API.
24364 * tparam.c (tparam1, tparam, tgoto):
24365 Use const pointers where appropriate.

24373 (turn_on_face, init_tty): Likewise.
24374 * termchar.h (struct tty_display_info): Likewise.
24376 * term.c (term_mouse_position): Rename local to avoid shadowing.
24378 * alloc.c (mark_ttys): Move decl from here ...
24379 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
