468 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
469 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
470 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
471 Adjust to changes in lisp.h and emacs.c, by using
472 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
473 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
474 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
475 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
476 instead of gdb_valbits.
477 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
478 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
479 instead of gdb_array_mark_flag.
480 (xboolvector): Get size from $->size, not $->header.size.
481 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
482 (xreload, hook-run, hookpost-run): Remove.
483 * emacs.c: Include <verify.h>.
484 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
485 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
486 Remove.
487 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
488 (gdb_USE_LSB_TAG): New enum constants.

490 Also define these as enum constants, so they're visible to GDB.
491 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
492 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
493 as constants, so they're visible to GDB.

495 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
496 Now enum constants, not macros, so they're visible to GDB.
497 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
498 more convenient now. All uses changed.
499 (VALMASK) [USE_LSB_TAG]: Also define in this case.

512 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
514 Use typedef for EMACS_INT, EMACS_UINT.
515 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
516 than macros. This simplifies debugging in the usual case, since
517 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
518 and it allows expressions involving EMACS_INT casts.
519 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
521 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

537 (init_buffer_once): Initialize indirection counters of
538 buffer_defaults and buffer_local_symbols (for sanity and safety).
540 2012-07-24 Eli Zaretskii <eliz@gnu.org>
542 * xdisp.c (init_iterator): Don't compute dimensions of truncation
543 and continuation glyphs on tooltip frames, leave them at zero.

573 Swap buffer text indirection counters in Fbuffer_swap_text.
574 * buffer.c (Fbuffer_swap_text): Swap indirections too.
575 This avoids crash reported by Christoph Scholtes at
576 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
578 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
580 * nsmenu.m (Popdown_data): New struct.
581 (pop_down_menu): p->pointer is Popdown_data. Release the pool and

603 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
605 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
606 as it's limited by the amount of memory, not by INT_MAX.
608 2012-07-21 Eli Zaretskii <eliz@gnu.org>
610 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
611 in special-event-map. See the discussion at

613 for the reasons.
615 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

1385 * nsterm.m (ns_term_init):
1386 Avoid the need for strncpy, by using build_string or
1387 make_unibyte_string directly. Use dtoastr, not snprintf.
1388 * process.c (Fmake_network_process): Diagnose service names that
1389 are too long, rather than silently truncating them or creating
1390 non-null-terminated names.
1391 (Fnetwork_interface_info): Likewise, for interface names.
1392 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1393 Prefer sprintf to strncat.

1405 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1406 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1407 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

1420 Optimize pure C strings initialization.
1421 * lisp.h (make_pure_string): Fix prototype.
1422 (build_pure_c_string): New function, defined as static inline. This
1423 provides a better opportunity to optimize away calls to strlen when
1424 the function is called with compile-time constant argument.
1425 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1426 argument, adjust users accordingly. Use build_pure_c_string where
1427 appropriate.
1428 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1429 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1430 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1432 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1434 Avoid calls to strlen in miscellaneous functions.
1435 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1436 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1437 * lread.c (openp): Likewise.
1439 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1441 Avoid calls to strlen in path processing functions.
1442 * fileio.c (file_name_as_directory): Add comment. Change to add
1443 srclen argument and return the length of result. Adjust users
1444 accordingly.
1445 (directory_file_name): Fix comment. Change to add srclen argument,

1457 * s/gnu.h (DATA_START): Move definitions to configure.
1459 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1460 We include usg5-4-common.h, which defines them both.
1462 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1463 O_RDONLY already includes it).
1465 Stop ns builds setting the EMACSLOADPATH environment variable.
1466 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1467 Now it does not set EMACSLOADPATH, just returns the load-path string.
1468 * nsterm.h: Update accordingly.
1469 * lread.c [HAVE_NS]: Include nsterm.h.
1470 (init_lread) [HAVE_NS]: Use ns_load_path.

1473 2012-07-09 Glenn Morris <rgm@gnu.org>
1475 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1476 since the included bsd-common.h does so.
1478 Stop ns builds setting the EMACSPATH environment variable.
1479 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1480 (ns_init_paths): Do not set EMACSPATH.
1481 * nsterm.h (ns_exec_path): Add it.
1482 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1483 Use ns_exec_path.
1485 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1487 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1489 * process.c (wait_reading_process_output): 'waitchannels' was unset
1490 when read_kbd || !NILP (wait_for_cell); fix this.
1492 Add GCC-style 'const' attribute to functions that can use it.
1493 * character.h (char_resolve_modifier_mask):
1494 * keyboard.h (make_ctrl_char):
1495 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1504 Add decls with ATTRIBUTE_CONST.
1506 Minor improvements to make_formatted_string.
1507 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1508 where int is good enough, as vsprintf returns an int.
1509 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1511 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1513 Use make_formatted_string to avoid double length calculation.
1514 * lisp.h (make_formatted_string): New prototype.

1538 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1540 Move marker debugging code under MARKER_DEBUG.
1541 * marker.c (MARKER_DEBUG): Move marker debugging code under
1542 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1543 for bootstrap with --enable-checking (~3x slowdown reported
1544 by Juanma Barranquero <lekktu@gmail.com>).
1545 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1547 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1549 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1550 See <http://bugs.gnu.org/11825#29>.
1552 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1554 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1555 has no font, use the frame's font. (Bug#11813)
1556 (display_line): Add commentary about displaying truncation glyphs
1557 on GUI frames.
1558 (produce_special_glyphs): Move here from term.c.
1560 * term.c (produce_special_glyphs): Move to xdisp.c.
1562 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1563 section.
1565 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1567 * xdisp.c (display_line): Avoid warning about implicit declaration
1568 of FRAME_FONT.
1570 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1572 * lisp.h: Remove empty conditional.
1574 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1576 * lread.c (load_path_check): Now static.
1578 Fix some minor --with-ns problems found by static checking.
1579 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1580 (x_set_font) [!HAVE_X_WINDOWS]:
1581 * image.c (xpm_load_image) [HAVE_NS]:
1582 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1583 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1584 Remove unused local.
1585 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1586 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1587 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1588 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1589 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1590 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1591 Fix pointer signedness problem.
1592 * xfaces.c (FRAME_X_FONT_TABLE):
1593 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1595 2012-07-07 Glenn Morris <rgm@gnu.org>
1597 * lread.c (load_path_check): New function, split from init_lread.
1598 (init_lread): Reorganize. Motivation:
1599 If EMACSLOADPATH is set, check/warn about that rather than the
1600 defaults, which we are not going to use. Hence we can remove
1601 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1602 Don't warn if site-lisp directories are missing.
1603 If not installed, start from a blank load-path, since
1604 PATH_LOADSEARCH refers to the eventual installation directories.
1606 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1608 Support truncation and continuation glyphs on GUI frames, when
1609 fringes are disabled. (Bug#11832)
1610 * xdisp.c (init_iterator): Get dimensions of truncation and
1611 continuation glyphs even if on GUI frames. Adjust
1612 it->last_visible_x on GUI frames when the left or right fringes,
1613 or both, are absent.
1614 (start_display, move_it_in_display_line_to): Handle the case of a
1615 GUI frame without a fringe to display continuation or truncation
1616 glyphs.
1617 (insert_left_trunc_glyphs): Support GUI frames: make sure
1618 truncation glyphs overwrite enough glyphs from the current line to
1619 have sufficient space in pixels.
1620 (display_line): Support truncation and continuation glyphs on GUI
1621 frames. If some spare pixels are left on the line after inserting
1622 the truncation glyphs, fill that space with a stretch glyph of a
1623 suitably computed width.
1625 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1626 produce_glyphs, to support GUI sessions.
1628 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1630 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1632 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1634 Do not require float-time's arg to fit in time_t (Bug#11825).
1635 This works better on hosts where time_t is unsigned, and where
1636 float-time is applied to the (negative) difference between two times.
1637 * editfns.c (decode_time_components): Last arg is now double *,
1638 not int *, and means to store all the result as a double, without
1639 worrying about whether the seconds part fits in time_t.
1640 All callers changed.
1641 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1642 All callers changed.
1643 (Ffloat_time): Do not fail merely because the specified time falls
1644 outside of time_t range.
1646 2012-07-07 Glenn Morris <rgm@gnu.org>
1648 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1649 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1650 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1652 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1654 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1655 Update dependencies.
1657 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1659 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1661 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1662 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1663 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1664 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1665 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1666 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1668 * xfont.c (compare_font_names): Redo to omit the need for casts.
1670 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1672 * xfns.c (Fx_change_window_property): Doc fix.
1673 * w32fns.c (Fx_change_window_property): Doc fix.
1675 * w32fns.c (Fx_window_property): Accept the same arguments as the
1676 X Windows version. Doc fix.
1677 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1679 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1680 Eli Zaretskii <eliz@gnu.org>
1682 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1683 Windows-specific code from nt/config.nt moved here.
1684 Obsolete settings removed.
1686 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1688 * process.c: Avoid unnecessary calls to gettime.
1689 (wait_reading_process_output): Don't get the time of day
1690 when gobbling data immediately and not waiting, as there's no need
1691 for it in that case. This removes a FIXME.
1693 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1695 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1696 is defined (Bug#11768).
1698 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1700 Fix marker debugging code.
1701 * marker.c (byte_char_debug_check): Do not perform the check
1702 if buffer is not multibyte.
1703 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1704 Call byte_char_debug_check with correct arguments.
1706 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1708 Compile marker debugging code only if ENABLE_CHECKING is defined.
1709 * marker.c (byte_char_debug_check, count_markers):
1710 Use only if ENABLE_CHECKING is defined.
1711 (byte_debug_flag): Remove.
1712 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1713 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1715 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1717 Avoid code repetition in marker-related functions.
1718 * marker.c (attach_marker): New function.
1719 (Fset_marker, set_marker_restricted, set_marker_both)
1720 (set_marker_restricted_both): Use it.
1721 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1722 Consistently rename charno to charpos.
1723 (marker_position): Add eassert.
1724 (marker_byte_position): Convert to eassert.
1726 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1740 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1741 (save_restriction_save): Use build_marker.
1742 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1743 * window.c (save_window_save): Likewise.
1745 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1747 Do not use Fdelete_overlay in delete_all_overlays
1748 to avoid redundant calls to unchain_overlay.
1749 * buffer.c (drop_overlay): New function.
1750 (delete_all_overlays, Fdelete_overlay): Use it.
1751 * minibuf.c (get_minibuffer): Fix comment.
1753 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1755 Port to OpenBSD 5.1 amd64.
1756 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1757 This is needed for OpenBSD, and should be harmless on all BSD systems.
1758 Also, include <sys/sysctl.h>, as it should be available on all
1759 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1760 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1761 use p_pid member, not kp_proc.pid.
1763 2012-07-06 Glenn Morris <rgm@gnu.org>
1765 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1767 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1769 More xmalloc and related cleanup.
1770 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1771 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
1772 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
1773 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
1774 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
1775 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
1776 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
1777 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1778 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1779 * xterm.c:
1780 Omit needless casts involving void * pointers and allocation.
1781 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1782 as the former is more robust if P's type is changed.
1783 Prefer xzalloc to xmalloc + memset 0.
1784 Simplify malloc-or-realloc to realloc.
1785 Don't worry about xmalloc returning a null pointer.
1786 Prefer xstrdup to xmalloc + strcpy.
1787 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1788 growing it.
1789 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1790 alloca of a constant.
1792 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1794 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1795 hscroll is larger than the line width. Fixes long and futile
1796 looping inside extend_face_to_end_of_line (on a TTY) producing
1797 glyphs that are not needed and thrown away.
1799 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1801 * marker.c (set_marker_restricted_both): Simplify by using
1802 clip_to_bounds.
1804 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1806 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1808 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1810 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
1811 not defined (Bug#11768).
1812 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1813 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)

1815 followed by gtk_box_set_homogeneous (Bug#11768).
1816 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1817 (update_theme_scrollbar_width, xg_create_scroll_bar):
1818 Use gtk_scrollbar_new (Bug#11768).
1819 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1820 (is_box_type): New function (Bug#11768).
1821 (xg_tool_item_stale_p): Call is_box_type.
1822 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1823 with default display (Bug#11768).
1825 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1827 * xdisp.c (window_hscroll_limited): New function.
1828 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1829 coordinates when window's hscroll is set to insanely large
1830 values. (Bug#11857)
1832 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

1835 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1837 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

1895 * fileio.c (time_error_value): Check the right error number.
1896 Problem reported by Troels Nielsen in
1897 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1899 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1901 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1902 This should be fixed in a better way; see Eli Zaretskii in
1903 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1904 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1906 * fileio.c (time_error_value): Rename from special_mtime.
1907 The old name's problems were noted by Eli Zaretskii in
1908 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1910 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1911 This variable's comment says Emacs needs at least one GDB-visible
1912 symbol of type enum pvec_type, to work around GDB problems.
1913 The symbol's value doesn't matter.
1915 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1916 that causes compilation to fail on pre-C99 compilers.
1918 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1920 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1923 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1925 * buffer.c (init_buffer_once): Fix initialization of
1926 headers for buffer_defaults and buffer_local_symbols.
1927 Reported by Juanma Barranquero <lekktu@gmail.com>.
1929 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1931 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1932 * lisp.h (enum pvec_type): Use fewer bits.
1933 (PSEUDOVECTOR_SIZE_BITS): New constant.
1934 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1935 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1936 change in pvec_type.
1937 (PSEUDOVECTOR_TYPEP): New macro.
1938 (TYPED_PSEUDOVECTORP): Use it.
1939 * fns.c (internal_equal): Adapt code to extract pvectype.
1940 * emacs.c (gdb_pvec_type): Update type.
1941 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1942 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1943 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1944 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1945 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1946 abusing vector->header.next.nbytes.
1947 (live_vector_p): Use PVEC_TYPE.
1948 (mark_object): Adapt code to extract pvectype. Use switch.
1950 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1952 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1953 Tighten new eassert a bit.
1955 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1957 Fix compilation with --enable-gcc-warnings and -O1
1958 optimization level.
1959 * doprnt.c (doprnt): Change type of tem to int, initialize
1960 to avoid compiler warning. Add eassert.
1961 * search.c (simple_search): Initialize match_byte to avoid
1962 compiler warning. Add eassert.
1964 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1966 Avoid weird behavior with large horizontal scrolls.
1967 Without this change, for example, large hscroll values would
1968 mess up Emacs's display on Fedora 15 x86, presumably due to
1969 overflows in int calculations in the display code.
1970 Also, if buffers had long lines, Emacs would freeze.
1971 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1972 (set_window_hscroll): New function, containing the old guts of
1973 Fset_window_hscroll. Return the clipped value.
1974 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1975 This avoids the need to check against PTRDIFF_MAX.
1977 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1979 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1981 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1983 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1985 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1986 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1987 since GCC 4.4.6 issues a bogus warning for them.
1989 Fix bugs in file timestamp newness comparisons.
1990 * fileio.c (Ffile_newer_than_file_p):
1991 * lread.c (Fload): Use full timestamp resolution of files,
1992 not just the 1-second resolution, so that files that are only
1993 slightly newer still count as newer.
1994 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1995 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1997 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1999 * fileio.c: Improve handling of file time marker. (Bug#11852)
2000 (special_mtime): New function.
2001 (Finsert_file_contents, Fverify_visited_file_modtime):
2002 Use it to set special mtime values consistently.
2004 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2006 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2007 marker for non-existing file. (Bug#11852)
2009 2012-07-03 Glenn Morris <rgm@gnu.org>
2011 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2012 and did not make it into globals.h).
2014 2012-07-03 Tom Tromey <tromey@redhat.com>
2016 * window.c (Fset_window_margins, Fset_window_fringes)
2017 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2018 * textprop.c (Fprevious_property_change): No longer static.

2023 * keyboard.c (Fcommand_execute): No longer static.
2024 Remove EXFUN.

2042 * fontset.h: Remove EXFUN.
2043 * font.h: Remove EXFUNs.
2044 * dosfns.c (system_process_attributes): Remove EXFUN.
2045 * keymap.h: Remove EXFUNs.
2046 * lisp.h: Remove EXFUNs.
2047 * w32term.h: Remove EXFUNs.
2048 * window.h: Remove EXFUNs.
2049 * xsettings.h: Remove EXFUN.
2050 * xterm.h: Remove EXFUN.
2052 2012-07-03 Glenn Morris <rgm@gnu.org>
2054 * lisp.h (Frandom): Make it visible to C.
2055 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2056 buffer for invisible buffers. (Bug#1229)
2058 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2060 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2061 values which aren't power of 2.
2062 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2063 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2064 accordingly.
2066 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2068 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2070 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2072 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2074 * alloc.c (allocate_vector_block): Remove redundant
2075 calls to mallopt if DOUG_LEA_MALLOC is defined.
2076 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2077 avoid calls to mallopt if zero_vector is returned.
2079 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2081 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2082 is enabled, avoid dereferencing NULL current_sblock if
2083 running undumped.
2085 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2087 Cleanup basic buffer management.
2088 * buffer.h (struct buffer): Change layout to use generic vector
2089 marking code. Fix some comments. Change type of 'clip_changed'
2090 to bitfield. Remove unused #ifndef old.
2091 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2092 (GET_OVERLAYS_AT): Fix indentation.
2093 (for_each_per_buffer_object_at): New macro.

2102 (mark_object): Use it. Adjust marking of misc objects
2103 and related comments.
2105 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2107 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2108 wrapper that is not needed because the wrapped code is a no-op (zero
2109 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2110 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2112 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2114 * alloc.c (mark_buffer): Simplify. Remove prototype.
2115 (mark_object): Add comment. Reorganize marking of vector-like
2116 objects. Use CHECK_LIVE for all vector-like objects except buffers
2117 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2118 redundant calls to mark_vectorlike for bool vectors.
2120 2012-06-30 Glenn Morris <rgm@gnu.org>
2122 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2124 * epaths.in (PATH_SITELOADSEARCH): New.
2125 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2126 This is rather than relying on --enable-locallisppath elements
2127 having "site-lisp" in their names. (Bug#10208#25, 11658)
2129 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2131 * w32proc.c (sys_select): Accept and ignore one more argument.
2133 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2135 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2136 (pselect) [!MS_DOS]: Redirect to sys_select.
2138 * sysdep.c: Don't include dos.h and dosfns.h.
2140 * process.c (sys_select):
2141 * msdos.c (sys_select): Accept one more argument and ignore it.
2143 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2144 adapt data types and code to that.
2146 * dosfns.c:
2147 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2148 which clashes with the gnulib function of the same name.
2150 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2152 * font.c (font_style_to_value, font_style_symbolic)
2153 (font_prop_validate_style): Add type checks for values in
2154 font_style_table.
2156 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2157 argument.
2158 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2159 uses.
2161 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2163 * xdisp.c (try_window_id): Undo last change.
2165 * w32.c (getwd): Adjust commentary about startup_dir.
2166 (init_environment): Always call sys_access, even in non-MSVC
2167 builds. Don't chdir to the directory of the Emacs executable.
2168 This undoes code from 1997 which was justified by the need to
2169 "avoid conflicts when removing and renaming directories". But its
2170 downside was that every relative file name was being interpreted
2171 relative to the directory of the Emacs executable, which can never
2172 be TRT. In particular, it broke sys_access when called with
2173 relative file names.
2174 (sys_access): Map GetLastError to errno.
2176 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2178 * window.h (struct window): Change type of 'fringes_outside_margins'
2179 to bitfield. Fix comment. Adjust users accordingly.

2181 Adjust comment.
2182 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2183 to ptrdiff_t.
2185 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2187 * gnutls.c (emacs_gnutls_handshake):
2188 Add QUIT to make the loop interruptible.
2190 2012-06-29 Glenn Morris <rgm@gnu.org>
2192 * charset.c (init_charset): Make lack of etc/charsets fatal.
2194 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2196 * editfns.c (region_limit): Fix type mismatch.
2198 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2200 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2201 undefined. Convert from xassert to eassert.
2202 * nsmenu.m: Convert from xassert to eassert.
2203 * nsterm.m: Likewise.
2205 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2207 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2209 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2211 Avoid integer overflow on scroll-left and scroll-right.
2212 * window.c (HSCROLL_MAX): New macro.
2213 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2214 overflow when requested scroll falls outside ptrdiff_t range.
2216 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2218 * window.h (struct window): Change type of 'hscroll',
2219 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2220 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2221 Adjust users accordingly.
2222 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2223 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2224 from EMACS_INT to ptrdiff_t.
2225 (make_window): Omit redundant initialization.
2227 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2229 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2231 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2233 * window.h (struct window): Change type of 'use_time' and
2234 'sequence_number' from Lisp_Object to int.
2235 * frame.c (make_frame): Adjust users accordingly.
2236 * print.c (print_object): Likewise.
2237 * window.c (select_window, Fwindow_use_time, make_parent_window)

2242 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2243 enabled with --enable-checking=[all,glyphs] configure option.
2244 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2245 adjust comments accordingly.
2246 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
2247 undefined, adjust comments accordingly.

2259 Generalize run-time debugging checks.
2260 * dispextern.h (XASSERTS): Remove.
2261 * fontset.c (xassert): Remove.

2368 Use sprintf return value instead of invoking strlen on result.
2369 In the old days this wasn't portable, since some sprintf
2370 implementations returned char *. But they died out years ago and
2371 Emacs already assumes sprintf returns int.
2372 Similarly for float_to_string.
2373 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2380 * xfns.c (syms_of_xfns):
2381 Use sprintf or float_to_string result to avoid need to call strlen.
2382 * data.c (Fnumber_to_string):
2383 Use make_unibyte_string, since the string must be ASCII.
2384 * lisp.h, print.c (float_to_string): Now returns int length.
2385 * term.c (produce_glyphless_glyph):
2386 Use sprintf result rather than recomputing it.
2388 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2389 * Makefile.in (ALL_CFLAGS):
2390 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2419 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2421 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2424 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2426 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2427 instead of truncating it to 63 (admittedly a generous limit).

2486 * dispnew.c (Fsleep_for, sit_for):
2487 * keyboard.c (kbd_buffer_get_event):
2488 * process.c (Faccept_process_output):
2489 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2490 This improves on the previous patch, which introduced a bug
2491 when time_t is unsigned and as wide as intmax_t.
2492 See <http://bugs.gnu.org/9000#51>.
2494 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2496 * dispnew.c (sit_for, Fsleep_for):

2511 Privately reported by Herbert J. Skuhra.
2512 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2513 All uses changed.
2514 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2515 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2517 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2519 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2520 last argument of make_unibyte_string.
2522 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2523 language ID in the event parameters.
2525 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2526 event.code, not the obscure "character set ID".
2528 2012-06-23 Chong Yidong <cyd@gnu.org>
2530 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

2550 Privately reported by Herbert J. Skuhra.
2551 [__FreeBSD__]: Remove "*/" typo after "#include".

2557 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2559 Support higher-resolution time stamps (Bug#9000).
2560 The time stamps are only nanosecond-resolution at the C level,
2561 since that's the best that any real-world system supports now.
2562 But they are picosecond-resolution at the Lisp level, as that's
2563 easy, and leaves room for future OS improvements.
2565 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2566 (LIBES): Use it.
2568 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2569 Don't get current time unless it's needed.
2571 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2572 now provides it if it's absent.
2573 (start_atimer): Port to higher-res time stamps.
2574 Check for time stamp overflow. Don't get current time more
2575 often than is needed.
2577 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2578 Include systime.h, not time.h.
2579 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2581 * dired.c: Include stat-time.h.
2582 (Ffile-attributes): File times now have higher resolution.
2584 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2585 (struct image): Timestamp now has higher resolution.
2587 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2588 has at least microseconds now. All uses removed.
2589 (update_frame, update_single_window, update_window, update_frame_1)
2590 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2592 * editfns.c (time_overflow): Now extern.
2593 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2594 (float-time, Fformat_time_string, Fcurrent_time_string)
2595 (Fcurrent_time_zone): Accept and generate higher-resolution
2596 time stamps.
2597 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2598 (decode_time_components, lisp_seconds_argument): New functions.
2599 (make_time): Now static.
2600 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2601 Report an error if the time is invalid, rather than having the caller
2602 do that.
2604 * fileio.c: Include <stat-time.h>
2605 (Fcopy_file): Copy higher-resolution time stamps.
2606 Prefer to set the time stamp via a file descriptor if that works.
2607 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2608 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2609 (Fvisited_file_modtime, Fset_visited_file_modtime):
2610 Support higher-resolution time stamps.
2612 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2614 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2616 * image.c (prepare_image_for_display, clear_image_cache)
2617 (lookup_image): Port to higer-resolution time stamps.
2619 * keyboard.c (start_polling, bind_polling_period):
2620 Check for time stamp overflow.
2621 (read_char, kbd_buffer_get_event, timer_start_idle)
2622 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2623 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2624 Port to higher-resolution time stamps. Do not assume time_t is signed.
2625 (decode_timer): New function. Timers are now vectors of length 9,
2626 not 8, to accommodate the picosecond component.
2627 (timer_check_2): Use it.
2629 * nsterm.m (select_timeout, timeval_subtract): Remove.
2630 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2631 as they're a bit more accurate and handle overflow better.
2632 (ns_select): Change prototype to be compatible with pselect.
2633 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2634 * nsterm.h (ns_select): Adjust prototype.
2636 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2637 us-resolution time stamps.
2638 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2640 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2642 * lisp.h (time_overflow): New decl.
2643 (wait_reading_process_output): First arg is now intmax_t, not int,
2644 to accommodate larger waits.
2646 * process.h (struct Lisp_Process.read_output_delay):
2647 Now counts nanoseconds, not microseconds.
2648 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2649 EMACS_HAS_USECS.
2650 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2651 (wait_reading_process_output):
2652 Port to ns-resolution time stamps.
2653 (Faccept_process_output, wait_reading_process_output):
2654 Check for time stamp overflow. Do not assume time_t is signed.
2655 (select_wrapper): Remove; we now use pselect.
2656 (Fprocess_attributes): Now generates ns-resolution time stamps.
2658 * sysdep.c: Include utimens.h. Don't include utime.h
2659 or worry about struct utimbuf; gnulib does that for us now.
2660 (gettimeofday): Remove; gnulib provides a substitute.
2661 (make_timeval): New function.
2662 (set_file_times): Now sets ns-resolution time stamps.
2663 New arg FD; all uses changed.
2664 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2665 (system_process_attributes):
2666 Now returns ns-resolution time stamp. All uses changed.
2667 Check for time stamp overflow.
2669 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2670 provides a substitute now.
2672 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2673 since it guarantees struct timespec.
2674 (EMACS_TIME): Now struct timespec, so that we can support
2675 ns-resolution time stamps.
2676 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2677 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2678 (EMACS_USECS): Remove.
2679 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2680 so multiply the arg by 1000 before storing it.
2681 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2682 New macros.
2683 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2684 Port to ns-resolution time stamps.
2685 (EMACS_TIME_NEG_P): Remove; replaced by....
2686 (EMACS_TIME_SIGN): New macro.
2687 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2688 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2689 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2690 (make_timeval, make_lisp_time, decode_time_components): New decls.
2691 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2692 that it mishandled time_t overflow. You can't compare by subtracting!
2693 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2694 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2696 * term.c: Include <sys/time.h>.
2697 (timeval_to_Time): New function, for proper overflow wraparound.
2698 (term_mouse_position, term_mouse_click): Use it.
2700 * undo.c (record_first_change): Support higher-resolution time stamps
2701 in the undo buffer.
2702 (Fprimitive_undo): Use them when restoring time stamps.
2704 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2705 (w32_get_internal_run_time):
2706 Port to higher-resolution Emacs time stamps.
2707 (ltime): Now accepts single 64-bit integer, as that's more convenient
2708 for callers.
2710 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2712 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2713 for compatibility with pselect. Support ns-resolution time stamps.
2715 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2717 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2718 Check for time stamp overflow, and support ns-resolution time stamps.
2720 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2721 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2722 (timeval_subtract): Remove; no longer needed.
2723 (XTflash, XTring_bell, x_wait_for_event):
2724 Port to ns-resolution time stamps. Don't assume time_t is signed.
2726 2012-06-22 Chong Yidong <cyd@gnu.org>
2728 * xdisp.c (x_consider_frame_title): Revert last change.
2730 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2732 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2733 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2734 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2735 staticidx goes up to 1597 out of 1600 = 0x640.)
2737 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2739 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2740 Otherwise, the umask might be mistakenly 0 while handling input signals.

2750 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2751 access to `contents' member of Lisp_Vector objects with AREF and ASET
2752 where appropriate.
2754 2012-06-19 Chong Yidong <cyd@gnu.org>
2756 * frame.c (delete_frame): When selecting a frame on a different
2757 text terminal, do not alter the terminal's top-frame.

2760 frame's selected window and its terminal's top-frame.
2761 (unwind_format_mode_line): Restore them.
2762 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2763 Callers changed.
2764 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2765 since tty frames can be explicitly named.
2766 (prepare_menu_bars): Likewise.
2768 * term.c (Ftty_top_frame): New function.
2770 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2772 Port byte-code-meter to modern targets.
2773 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2774 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2775 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2776 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2777 (METER_1, METER_2): Simplify.
2779 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2781 * data.c (Fdefalias): Return `symbol' (bug#11686).
2783 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2785 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2786 gets killed during executing of this function (Bug#11665).
2787 Try to always return Qt when the buffer has been actually killed.
2788 (Vkill_buffer_query_functions): In doc-string say that functions
2789 run by this hook should not change the current buffer.
2791 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2793 Fix recently-introduced process.c problems found by static checking.

2811 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2813 * lisp.h (eassert): Assume C89 or later.
2814 This removes the need for CHECK.
2815 (CHECK): Remove. Its comments about always evaluating its
2816 argument were confusing, as 'eassert' typically does not evaluate
2817 its argument.
2819 * coding.c (produce_chars): Use ptrdiff_t, not int.
2821 * xterm.c (x_draw_underwave): Check for integer overflow.
2822 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
2824 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
2826 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

2913 2012-06-16 Eli Zaretskii <eliz@gnu.org>
2915 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
2916 If all the glyphs of the glyph row came from strings, and we have no
2917 cursor positioning clues, put the cursor on the first glyph of the
2918 row.
2919 (handle_face_prop): Use chunk-relative overlay string index when
2920 indexing into it->string_overlays array. (Bug#11653)
2921 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

2934 info of the initial frame. (Bug#11677)
2936 2012-06-14 Paul Eggert <eggert@cs.ucla.edu>
2938 * .gdbinit (xgetint): Fix recently-introduced paren typo.
2939 Assume USE_2_TAGS_FOR_INTS.
2940 (xreload): Adjust $tagmask width to match recent lisp.h change.

2944 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
2945 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

2947 (INTTYPEBITS): New macro, for clarity.
2948 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
2949 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

2965 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
2966 instead of union.
2967 (XLI, XIL): Define.

2995 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2996 * alloc.c (make_number) [!defined make_number]:

3006 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3007 code works fine either way, and efficiency is not a concern here,
3008 as the union type is for debugging, not for production.
3009 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3010 Use an inline function on all platforms when using the union type,
3011 since this is simpler and 'static inline' can be used portably
3012 within Emacs now.
3013 (LISP_INITIALLY_ZERO): New macro.
3014 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

3043 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
3044 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
3046 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
3048 * alloc.c (make_byte_code): New function.

3102 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3104 * dispnew.c (showing_window_margins_p): Undo last change, which

3118 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3120 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3122 * alloc.c (allocate_vectorlike): Fix last change.
3124 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3126 Block-based vector allocation of small vectors.

3144 0 items. Allocate new vector from block if vector size is less than
3145 or equal to VBLOCK_BYTES_MAX.
3146 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
3147 (init_alloc_once): Add call to init_vectors.
3149 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
3151 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
3153 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3155 * doprnt.c (doprnt): Truncate multibyte char correctly.
3156 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3157 would mishandle a string argument "Xc" if X was a multibyte
3158 character of length 2: it would truncate after X's first byte
3159 rather than including all of X.
3161 2012-06-06 Chong Yidong <cyd@gnu.org>
3163 * buffer.c (word_wrap): Doc fix.
3165 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

3179 Restore PaX flags to their default. (Bug#11398)
3181 2012-06-03 Chong Yidong <cyd@gnu.org>
3183 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte

3193 * buffer.c (buffer_local_value_1): New function, split from
3194 Fbuffer_local_value; can return Qunbound.
3195 (Fbuffer_local_value): Use it.
3196 (Vmode_line_format): Docstring tweaks.
3198 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

3202 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
3204 * keyboard.c: Export real-this-command to Elisp.
3205 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
3206 and DEFVAR it. Update all users.
3208 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3210 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3212 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3213 Convert pctcpu and pctmem to Lisp float properly.
3214 Let the compiler fold better, as 100.0/0x8000 is exact.
3216 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3218 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3219 cons_block.
3221 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3223 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3225 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3227 For a 'struct window', replace some Lisp_Object fields to
3228 bitfields where appropriate, remove unused fields.
3229 * window.h (struct window): Remove unused 'last_mark_x' and
3230 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3231 change it's type from Lisp_Object to bitfield.
3232 Change type of 'force_start', 'optional_new_start',
3233 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3234 fields from Lisp_Object to bitfield. Adjust users accordingly.
3236 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3238 Pacify gcc -Wdouble-precision when using Xaw.
3239 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3240 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3241 Use 'float' consistently, rather than 'float' in most places
3242 and 'double' in a couple of places.
3244 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3246 * xdisp.c (handle_stop): Detect whether we have overlay strings
3247 loaded by testing it->current.overlay_string_index to be
3248 non-negative, instead of checking whether n_overlay_strings is
3249 positive. (Bug#11587)
3251 2012-05-31 Chong Yidong <cyd@gnu.org>
3253 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3255 * doc.c (Fsubstitute_command_keys): Doc fix.
3257 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3259 * search.c (search_buffer): Remove calls to
3260 r_alloc_inhibit_buffer_relocation, as it is now called by
3261 maybe_unify_char, which was the cause of relocation of buffer text
3262 in bug#11519.
3264 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3266 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3267 for the duration of call to load_charset, to avoid problems with
3268 callers of maybe_unify_char that access buffer text through C
3269 pointers.
3271 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3272 decrement the inhibition flag, instead of just setting or
3273 resetting it.
3275 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3277 Remove obsolete '#define static' cruft.
3278 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3279 This #undef was "temporary" in 2000; it is no longer needed
3280 now that '#define static' has gone away.
3281 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3282 (gray_bitmap_bits): Remove; no longer needed.
3283 All uses replaced with definiens.
3284 * xterm.c: Include "bitmaps/gray.xbm".
3286 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3288 Clean up __executable_start, monstartup when --enable-profiling.
3289 The following changes affect the code only when profiling.
3290 * dispnew.c (__executable_start): Rename from safe_bcopy.
3291 Define only on platforms that need it.
3292 * emacs.c: Include <sys/gmon.h> when profiling.
3293 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3294 (__executable_start): Remove decl, since lisp.h does it now.
3295 (safe_bcopy): Remove decl; no longer has that name.
3296 (main): Coalesce #if into single bit of code, for simplicity.
3297 Cast pointers to uintptr_t, since standard libraries want integers
3298 and not pointers.
3299 * lisp.h (__executable_start): New decl.
3301 2012-05-31 Glenn Morris <rgm@gnu.org>
3303 * image.c (Fimagemagick_types): Doc fix.
3305 2012-05-30 Jim Meyering <meyering@redhat.com>
3307 * callproc.c (Fcall_process_region): Include directory component
3308 in mkstemp error message (Bug#11586).
3310 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3312 * alloc.c, lisp.h (make_pure_vector): Now static.
3314 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
3316 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
3317 Move to byte-run.el.
3318 (Fautoload): Do the hash-doc more carefully.
3319 * data.c (Fdefalias): Purify definition, except for keymaps.
3320 (Qdefun): Move from eval.c.
3321 * lisp.h (Qdefun): Remove.
3322 * lread.c (read1): Tiny simplification.
3324 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3326 Do not create empty overlays with the evaporate property (Bug#9642).
3327 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3328 Bug#9642, but explicitly check that the buffer the overlay would
3329 be moved to is live and rearrange lines to make sure that errors
3330 will not put the overlay in an inconsistent state.
3331 (Fdelete_overlay): Cosmetics.
3333 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3335 * w32term.c (my_bring_window_to_top): New function.
3336 (x_raise_frame): Use handle returned by DeferWindowPos, which
3337 could be different from the original one.
3338 Call my_bring_window_to_top instead of my_set_foreground_window.
3339 (Bug#11513)
3341 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3342 by calling BringWindowToTop.
3344 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3345 (WM_EMACS_END): Increase by one.
3347 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3349 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3350 This avoids undefined behavior that might cause the eassert
3351 to not catch an out-of-range value.
3353 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3355 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3356 Update dependencies.
3358 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3360 * bidi.c (bidi_mirror_char): Fix last change.
3362 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3364 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3365 when referring to sectname field in printf format.
3367 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3369 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3370 Only r_alloc_inhibit_buffer_relocation needed to be added;
3371 the others were already declared.
3373 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3374 before checking whether it's out of range. Put the check inside
3375 eassert. See
3376 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3378 2012-05-27 Ken Brown <kbrown@cornell.edu>
3380 * callproc.c (Fcall_process): Restore a line that was accidentally
3381 commented out in the 2011-02-13 change (bug#11547).
3383 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3385 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3386 defined on ralloc.c.
3388 * buffer.c [REL_ALLOC]: Remove prototypes of
3389 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3390 they are now on lisp.h.
3392 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3394 * search.c (search_buffer): Use it to inhibit relocation of buffer
3395 text while re_search_2 is doing its job, because re_search_2 is
3396 passed C pointers to buffer text. (Bug#11519)
3398 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3399 Update value to 24.
3401 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3402 state after an additional call to move_it_in_display_line_to, keep
3403 the values of it->max_ascent and it->max_descent found for the
3404 entire line.
3405 (pos_visible_p): Revert the comparison against bottom_y to what it
3406 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3407 (Bug#11464)
3409 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3411 Fix coding-related core dumps with gcc -ftrapv.
3412 The code was computing A - B, where A and B are pointers, and B is
3413 random garbage. This can lead to core dumps on platforms that
3414 have special pointer registers, and it also leads to core dumps on
3415 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3416 A - B only when B is initialized properly.
3417 * coding.c (coding_set_source, coding_set_destination): Return void.
3418 (coding_change_source, coding_change_destinations): New functions,
3419 with the old behaviors of coding_set_source and coding_set_destination.
3420 All callers that need an offset changed to use these new functions.
3422 2012-05-26 Glenn Morris <rgm@gnu.org>
3424 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3426 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3428 Extend mouse support on W32 text-mode console.
3429 * xdisp.c (draw_row_with_mouse_face):
3430 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3432 * w32console.c: Include window.h.
3433 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3434 New functions.
3435 (initialize_w32_display): Initialize mouse-highlight data.
3437 * w32inevt.c: Include termchar.h and window.h.
3438 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3439 moves, call note_mouse_highlight. If help_echo changed, call
3440 gen_help_event to produce help-echo message in the echo area.
3441 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3442 highlight info.
3444 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3446 * lread.c (read1): Simplify slightly to avoid an overflow warning
3447 with GCC 4.7.0 on x86-64.
3449 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3451 * bidi.c (bidi_mirror_char): Revert last change: an int is
3452 definitely wide enough here.
3454 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3456 Fix integer width and related bugs (Bug#9874).
3457 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3458 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3459 (string_bytes, check_sblock, allocate_string_data):
3460 (compact_small_strings, Fmake_bool_vector, make_string)
3461 (make_unibyte_string, make_multibyte_string)
3462 (make_string_from_bytes, make_specified_string)
3463 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3464 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3465 (mark_vectorlike):
3466 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3467 (allocate_pseudovector):
3468 Use int, not EMACS_INT, where int is wide enough.
3469 (inhibit_garbage_collection, Fgarbage_collect):
3470 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3471 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3472 int might not be wide enough.
3473 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3474 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3475 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3476 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3477 (bidi_level_of_next_char, bidi_move_to_visually_next):
3478 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3479 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3480 (Fkill_buffer, Fset_buffer_major_mode)
3481 (advance_to_char_boundary, Fbuffer_swap_text)
3482 (Fset_buffer_multibyte, overlays_at, overlays_in)
3483 (overlay_touches_p, struct sortvec, record_overlay_string)
3484 (overlay_strings, recenter_overlay_lists)
3485 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3486 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3487 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3488 (Foverlay_recenter, last_overlay_modification_hooks_used)
3489 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3490 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3491 (validate_region): Omit unnecessary test for b <= e,
3492 since that's guaranteed by the previous test.
3493 (adjust_overlays_for_delete): Avoid pos + length overflow.
3494 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3495 (report_overlay_modification):
3496 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3497 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3498 Omit pointer cast, which isn't needed anyway, and doesn't work
3499 after the EMACS_INT -> ptrdiff_t change.
3500 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3501 * buffer.h: Adjust decls to match defn changes elsewhere.
3502 (struct buffer_text, struct buffer):
3503 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3504 Use EMACS_INT, not int, where int might not be wide enough.
3505 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3506 not int, to avoid needless 32-bit limit on 64-bit hosts.
3507 (exec_byte_code): Use tighter memory-full test, one that checks
3508 for alloca overflow. Don't compute the address of the object just
3509 before an array, as that's not portable. Use EMACS_INT, not
3510 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3511 * callint.c (Fcall_interactively):
3512 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3513 * callproc.c (call_process_kill, Fcall_process):
3514 Don't assume pid_t fits into an Emacs fixnum.
3515 (call_process_cleanup, Fcall_process, child_setup):
3516 Don't assume pid_t fits into int.
3517 (call_process_cleanup, Fcall_process, delete_temp_file)
3518 (Fcall_process_region):
3519 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3520 (Fcall_process): Simplify handling of volatile integers.
3521 Use int, not EMACS_INT, where int will do.
3522 * casefiddle.c (casify_object, casify_region, operate_on_word)
3523 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3524 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3525 (casify_object): Avoid integer overflow when overallocating buffer.
3526 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3527 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3528 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3529 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3530 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3531 integers are now checked earlier. All uses replaced with XINT.
3532 (ccl_driver):
3533 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3534 For CCL_MapSingle, check that content and value are in int range.
3535 (ccl_driver, Fregister_code_conversion_map):
3536 Check that Vcode_version_map_vector is a vector.
3537 (resolve_symbol_ccl_program): Check that vector header is in range.
3538 Always copy the vector, so that we can check its contents reliably
3539 now rather than having to recheck each instruction as it's being
3540 executed. Check that vector words fit in 'int'.
3541 (ccl_get_compiled_code, Fregister_ccl_program)
3542 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3543 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3544 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3545 contents are in range.
3546 (Fccl_execute_on_string): Check that status is in range.
3547 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3548 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3549 Accept and return EMACS_INT, not int, because callers can pass values
3550 out of 'int' range.
3551 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3552 (multibyte_chars_in_text, parse_str_as_multibyte)
3553 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
3554 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3555 (string_escape_byte8, Fget_byte):
3556 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3557 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3558 avoid mishandling large integers.
3559 * character.h: Adjust decls to match defn changes elsewhere.
3560 * charset.c (load_charset_map_from_file, find_charsets_in_text)
3561 (Ffind_charset_region):
3562 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3563 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
3564 (load_charset_map_from_vector, Fdefine_charset_internal):
3565 Don't assume fixnum fits in int.
3566 (load_charset_map_from_vector, Fmap_charset_chars):
3567 Remove now-unnecessary CHECK_NATNUMs.
3568 (Fdefine_charset_internal): Check ranges here, more carefully.
3569 Don't rely on undefined behavior with signed left shift overflow.
3570 Don't assume unsigned int fits into fixnum, or that fixnum fits
3571 into unsigned int. Don't require max_code to be a valid fixnum;
3572 that's not true for gb10830 4-byte on a 32-bit host. Allow
3573 invalid_code to be a cons, for the same reason. Require code_offset
3574 to be a character. Avoid int overflow if max_char is close
3575 to INT_MAX.
3576 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3577 this is intended anyway and avoids some undefined behavior.
3578 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3579 INDEX_TO_CODE_POINT, as that's what it expects.
3580 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3581 * charset.h (DECODE_CHAR): Return int, not unsigned;
3582 this is what was intended anyway, and it avoids undefined behavior.
3583 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3584 integer-overflow issues.
3585 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3586 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3587 where the argument is EMACS_INT, and this behavior is not intended.
3588 * chartab.c (Fmake_char_table, Fset_char_table_range)
3589 (uniprop_get_decoder, uniprop_get_encoder):
3590 Don't assume fixnum fits in int.
3591 * cmds.c (move_point): New function, that does the gist of
3592 Fforward_char and Fbackward_char, but does so while checking
3593 for integer overflow more accurately.
3594 (Fforward_char, Fbackward_char): Use it.
3595 (Fforward_line, Fend_of_line, internal_self_insert)
3596 (internal_self_insert):
3597 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3598 Fix a FIXME, by checking for integer overflow when calculating
3599 target_clm and actual_clm.
3600 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
3601 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

4304 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4305 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4306 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4307 * s/ms-w32.h (DATA_START):
4308 Move here from removed file m/intel386.h.
4309 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4310 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4312 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4314 Assume C89 or later.
4315 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
4316 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
4317 (xrealloc):
4318 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
4319 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
4320 * textprop.c, tparam.c (NULL): Remove.
4321 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
4322 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4323 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4324 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4325 * xterm.c (input_signal_count): Assume volatile works.
4327 2012-05-21 Ken Brown <kbrown@cornell.edu>
4329 * xgselect.c (xg_select): Fix first argument in call to 'select'
4330 (bug#11508).
4332 2012-05-20 Ken Brown <kbrown@cornell.edu>
4334 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4335 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4337 2012-05-19 Ken Brown <kbrown@cornell.edu>
4339 * xfns.c (x_in_use): Remove `static' qualifier.
4340 * xterm.h (x_in_use): Declare.
4341 * xgselect.c: Include xterm.h.
4342 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4343 and `display_arg' (bug#9754).
4345 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4347 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4349 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4350 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4352 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4354 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4356 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4357 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4359 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4360 reference to image_cache->refcount.
4361 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4363 2012-05-17 Juri Linkov <juri@jurta.org>
4365 * search.c (Fword_search_regexp, Fword_search_backward)
4366 (Fword_search_forward, Fword_search_backward_lax)
4367 (Fword_search_forward_lax): Move functions to isearch.el
4368 (bug#10145, bug#11381).
4370 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4372 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4374 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4376 * lread.c (init_obarray): Declare Qt and Qnil as special.
4378 2012-05-14 Glenn Morris <rgm@gnu.org>
4380 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4381 Put "libexec" before "bin", for the sake of init_callproc_1.
4383 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4385 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4387 * unexaix.c: Port to more-recent AIX compilers.
4388 (report_error, report_error_1, make_hdr, copy_sym)
4389 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4390 Make arguments const char *, not char *, to avoid violations of C
4391 standard and to fix some AIX warnings reported by Gilles Pion.
4393 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4395 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4396 already have overlays loaded.
4397 (handle_single_display_spec): Before returning without displaying
4398 fringe bitmap, synchronize the bidi iterator with the main display
4399 iterator, by calling iterate_out_of_display_property.
4400 (iterate_out_of_display_property): Detect buffer iteration by
4401 testing that it->string is a Lisp string.
4402 (get_next_display_element): When the current object is exhausted,
4403 and there's something on it->stack, call set_iterator_to_next to
4404 proceed with what's on the stack, instead of returning zero.
4405 (set_iterator_to_next): If called at the end of a Lisp string,
4406 proceed to consider_string_end without incrementing string
4407 position. Don't increment display vector index past the end of
4408 the display vector. (Bug#11417)
4409 (pos_visible_p): Don't report a position visible when move_it_to
4410 stopped at the last line of window, which happens to be scanned
4411 backwards by the bidi iteration. (Bug#11464)
4413 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4415 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4416 and right-margin display specs even if the spec is invalid or we
4417 are on a TTY, and thus unable to display on the fringes.
4418 That's because the text with the property will not be displayed anyway,
4419 so we need to signal to the caller that this is a "replacing"
4420 display spec. This fixes display when the spec is invalid or we
4421 are on a TTY.
4423 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4425 * unexaix.c (make_hdr): Fix typo in prototype.
4426 This bug broke the build on AIX. Problem reported by Gilles Pion.
4428 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4430 * keyboard.c (kbd_buffer_get_event): Read special events also in
4431 batch mode. (Bug#11415)
4433 2012-05-12 Glenn Morris <rgm@gnu.org>
4435 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4437 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4439 * lisp.mk (lisp): Add newcomment.elc.
4441 2012-05-12 Glenn Morris <rgm@gnu.org>
4443 * Makefile.in (MKDIR_P): New, set by configure.
4444 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4446 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4448 Remove unused function hourglass_started.
4449 * dispextern.h (hourglass_started):
4450 * w32fns.c (hourglass_started):
4451 * xdisp.c (hourglass_started): Remove.
4453 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4455 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4456 Update dependencies.
4458 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4460 * xgselect.c (xg_select): Put maxfds+1 into a var.
4461 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4463 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4465 2012-05-10 Dave Abrahams <dave@boostpro.com>
4467 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4468 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4470 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4472 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4473 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4474 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4475 Initialize xd_registered_buses.
4477 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4479 Untag more efficiently if USE_LSB_TAG.
4480 This is based on a proposal by YAMAMOTO Mitsuharu in
4481 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4482 For an admittedly artificial (nth 8000 longlist) benchmark on
4483 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4484 Emacs's overall text size by 1%.
4485 * lisp.h (XUNTAG): New macro.
4486 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4487 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4488 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4489 * eval.c (Fautoload):
4490 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4491 * frame.h (XFRAME): Use XUNTAG.
4493 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4494 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4495 Remove unportable assumptions about print widths of types like
4496 dbus_uint32_t.
4497 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4498 intptr_t when converting between pointer and integer, to avoid GCC
4499 warnings about wrong width.
4501 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4503 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4504 stack for each reader_thread, instead of defaulting to 8MB
4505 determined by the linker. This avoids failures in creating
4506 subprocesses on Windows 7, see the discussion in this thread:
4507 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4509 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4511 Fix up display of the *Minibuf-0* buffer in the mini window.
4512 * keyboard.c (read_char): Don't clear the echo area if there's no
4513 message to clear.
4514 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4515 contents of *Minibuf-0*) if there's no message displayed in its stead.
4517 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4519 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4520 batch mode.
4522 2012-05-06 Chong Yidong <cyd@gnu.org>
4524 * lisp.mk (lisp): Update.
4526 2012-05-05 Jim Meyering <meyering@redhat.com>
4528 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4530 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4532 * data.c (PUT_ERROR): New macro.
4533 (syms_of_data): Use it. Add new error type `user-error'.
4534 * undo.c (user_error): New function.
4535 (Fprimitive_undo): Use it.
4536 * print.c (print_error_message): Adjust print style for `user-error'.
4537 * keyboard.c (user_error): New function.
4538 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4540 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4542 Do not limit current-time-string to years 1000..9999.
4543 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4544 (Fcurrent_time_string): Support any year that is supported by the
4545 underlying localtime representation. Don't use asctime, as it
4546 has undefined behavior for years outside the range -999..9999.
4548 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4550 Fix race conditions involving setenv, gmtime, localtime, asctime.
4551 Without this fix, interrupts could mess up code that uses these
4552 nonreentrant functions, since setting TZ invalidates existing
4553 tm_zone or tzname values, and since most of these functions return
4554 pointers to static storage.
4555 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4556 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4557 Grow the critical sections to include not just invoking
4558 localtime/gmtime, but also accessing these functions' results
4559 including their tm_zone values if any, and any related TZ setting.
4560 (format_time_string): Last arg is now struct tm *, not struct tm **,
4561 so that the struct tm is saved in the critical section.
4562 All callers changed. Simplify allocation of initial buffer, partly
4563 motivated by the fact that memory allocation needs to be outside
4564 the critical section.
4566 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4568 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4569 with RESET_INTERVAL.
4571 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4572 Remove duplicated buffer name initialization.
4574 2012-05-02 Jim Meyering <jim@meyering.net>
4576 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4578 * xfns.c (x_window): Use xstrdup (Bug#11375).
4580 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4582 * xdisp.c (pos_visible_p): If already at a newline from the
4583 display string before the 'while' loop, don't walk back the glyphs
4584 from it3.glyph_row. Solves assertion violation when the display
4585 string begins with a newline (egg.el). (Bug#11367)
4587 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4589 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4590 Move to simple.el.
4592 2012-05-01 Glenn Morris <rgm@gnu.org>
4594 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4595 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4596 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4597 All were removed before 23.1.
4599 * dispnew.c: Remove HAVE_LIBNCURSES test;
4600 it is always true on relevant platforms.
4602 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4603 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4605 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4607 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4609 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4610 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4611 Remove.
4613 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4615 Do not avoid creating empty evaporating overlays (Bug#9642).
4616 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4617 That is, do not delete an evaporating overlay if it becomes
4618 empty after its bounds are adjusted to fit within its buffer.
4619 This fix caused other problems, and I'm reverting it until we get
4620 to the bottom of them.
4622 2012-04-27 Chong Yidong <cyd@gnu.org>
4624 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4626 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4628 * xdisp.c (pos_visible_p): If the window start position is beyond
4629 ZV, start the display from buffer beginning. Prevents assertion
4630 violation in init_iterator when the minibuffer window is scrolled
4631 via the scroll bar.
4633 * window.c (window_scroll_pixel_based): Likewise.
4635 2012-04-27 Chong Yidong <cyd@gnu.org>
4637 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4639 2012-04-27 Glenn Morris <rgm@gnu.org>
4641 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4642 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4644 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4646 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4647 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4649 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4651 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4652 display element, check also the underlying string or buffer
4653 character. (Bug#11341)
4655 * w32menu.c: Include w32heap.h.
4656 (add_menu_item): If the call to AppendMenuW (via
4657 unicode_append_menu) fails, disable Unicode menus only if we are
4658 running on Windows 9X/Me.
4660 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4662 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4663 (xgetint): Add missing shift for LSB tags.
4665 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4667 * keyboard.c (read_char): Don't wipe echo area for select window
4668 events: These might get delayed via `mouse-autoselect-window'
4669 (Bug#11304).
4671 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4673 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4674 manipulation of :loaded-from data.
4676 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4678 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4679 now a cons (bug#11311).
4681 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4683 Do not create empty overlays with the evaporate property (Bug#9642).
4684 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4685 if it becomes empty after its bounds are adjusted to fit within
4686 its buffer. Without this fix, in a nonempty buffer (let ((o
4687 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4688 yields an empty overlay that has the evaporate property, which is
4689 not supposed to happen.
4691 Fix minor GTK3 problems found by static checking.
4692 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4693 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4694 (struct _EmacsFixedClass, emacs_fixed_get_type):
4695 Move decls here from emacsgtkfixed.h, since they needn't be public.
4696 (emacs_fixed_get_type): Now static.
4697 (emacs_fixed_class_init): Omit unused local.
4698 (emacs_fixed_child_type): Remove; unused.
4699 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4700 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4701 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4702 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4703 (EMACS_FIXED_GET_CLASS): Remove; unused.
4704 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4706 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4707 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4709 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4711 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4712 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4713 (__malloc_size_t, __malloc_ptrdiff_t):
4714 Remove. All uses removed, replaced by the definiens if needed,
4715 since we can assume C89 or better now.
4716 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4717 (protect_malloc_state, align, get_contiguous_space)
4718 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4723 (special_realloc, _realloc_internal_nolock, _realloc_internal)
4724 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4725 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4726 Define using prototypes, not old style.
4727 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4728 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4729 (align): Don't assume that signed integer overflow wraps around.
4730 Omit unused local var.
4731 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4732 (_free_internal_nolock, memalign, mallochook, reallochook):
4733 Omit no-longer-needed casts.
4734 (valloc): Use getpagesize, not __getpagesize.
4735 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
4736 (struct hdr): The 'magic' member is now size_t, not unsigned long.
4738 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4740 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
4742 Move functions from C to Lisp. Make non-blocking method calls
4743 the default. Implement further D-Bus standard interfaces.
4745 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
4746 (QCdbus_request_name_allow_replacement)

4792 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4793 since the two debugging options are incompatible.
4794 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4795 is defined.
4796 (mem_init, mem_insert, mem_insert_fixup):
4797 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
4798 (NEED_MEM_INSERT): Remove; no longer needed.
4800 2012-04-22 Leo Liu <sdl.web@gmail.com>
4802 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
4804 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4806 * sysdep.c [__FreeBSD__]: Minor cleanups.

4813 * sysdep.c (list_system_processes, system_process_attributes):
4814 Add implementation for FreeBSD (Bug#5243).

4828 is nil.
4829 (print_object): Check for cycles even when print-circle is nil and
4830 print-gensym is t, but only check print_depth if print-circle is nil.
4832 2012-04-20 Chong Yidong <cyd@gnu.org>
4834 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4835 set the status to "failed" and ensure that sentinel is run.
4837 2012-04-20 Glenn Morris <rgm@gnu.org>

4848 row, return zero immediately.
4849 (try_cursor_movement): If inside continuation line, don't back up
4850 farther than the first row after the header line, if any.
4851 Don't consider the header-line row as "partially visible", even if
4852 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4854 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4889 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
4890 New extern decls, to avoid calling undeclared functions.
4891 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4892 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4893 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4894 (NEED_MEM_INSERT): New macro.
4895 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4896 Remove one incorrect comment and fix another.

4910 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4911 Remove decls. This fixes an "It stinks!".
4913 * alloc.c (which_symbols): Fix alignment issue / type clash.
4915 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4917 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4928 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4930 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4931 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4932 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4933 * s/netbsd.h, s/sol2-6.h:
4934 Remove definition of GC_MARK_STACK, since the default now works.
4935 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4936 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4937 no longer the default.
4938 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4940 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4963 2012-04-11 Daniel Colascione <dancol@dancol.org>
4965 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4966 against is gone. It's better to use vfork now so that when Cygwin
4967 gains a new, working vfork, we use it automatically (bug#10398).
4969 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4971 * window.c (save_window_save): Obey window-point-insertion-type.

4990 being loaded (bug#10424).
4992 2012-04-09 Glenn Morris <rgm@gnu.org>
4994 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4995 not just in the obarray, before snarfing them. (Bug#11036)

5013 attempts per process (connection).
5015 2012-04-09 Chong Yidong <cyd@gnu.org>
5017 * eval.c (Fuser_variable_p, user_variable_p_eh)

5022 * minibuf.c (Fread_variable): Callers changed.
5024 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5026 * xdisp.c (set_cursor_from_row): If the display string appears in
5027 the buffer at position that is closer to point than the position
5028 after the display string, display the cursor on the first glyph of
5029 the display string. Fixes cursor display when a 'display' text
5030 property immediately follows invisible text. (Bug#11094)
5032 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5034 composite.c: use 'double' consistently
5035 * composite.c (get_composition_id): Use 'double' consistently
5036 instead of converting 'float' to 'double' and vice versa; this is
5037 easier to understand and avoids a GCC warning.
5039 2012-04-09 Glenn Morris <rgm@gnu.org>
5041 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5042 preparation for dumping it with emacs. (Bug#4789)

5084 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5085 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5086 [!WINDOWSNT]: New macros.
5087 (init_libxml2_functions, libxml2_loaded_p): New functions.
5088 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5089 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5090 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5091 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5092 linked in).
5093 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5094 Call init_libxml2_functions before calling libxml2 functions.
5095 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5097 * emacs.c: Don't include libxml/parser.h.
5098 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5099 xmlCleanupParser directly.
5101 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5103 2012-04-07 Eli Zaretskii <eliz@gnu.org>

5106 point, use it.vpos to compute how many lines to backtrack after
5107 move_it_to point. (Bug#11133)
5109 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5111 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5112 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5113 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5114 macros related to unification of CJK characters. For the details,
5115 see the discussion following the message here:
5116 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5118 2012-04-04 Chong Yidong <cyd@gnu.org>

5132 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5134 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5135 position we get to after a call to move_it_to fails the
5136 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5137 only if we wind up in a string from display property. (Bug#11063)
5139 * window.c (Fdelete_other_windows_internal): Invalidate the row
5140 and column information about mouse highlight, so that redisplay
5141 restores it after reallocating the glyph matrices. (Bug#7464)
5143 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5144 string comes from a `display' text property, use the buffer
5145 position of that property as if we actually saw that position in
5146 the row's glyphs.
5147 (move_it_by_lines): Remove the assertion that
5148 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5149 violated when there's a before-string at the beginning of a line.
5150 (Bug#11063)
5152 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5154 * xdisp.c (append_space_for_newline): If the default face was
5155 remapped, use the remapped face for the appended newline.
5156 (extend_face_to_end_of_line): Use the remapped default face for
5157 extending the face to the end of the line.
5158 (display_line): Call extend_face_to_end_of_line when the default
5159 face was remapped. (Bug#11068)
5161 2012-03-29 Eli Zaretskii <eliz@gnu.org>

5181 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5182 (command_loop_1): Use it; inhibit selection update for

5191 * dispextern.h (struct glyph): Change the bit length of
5192 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5194 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5196 * s/ms-w32.h (tzname): Include time.h before redirecting to
5197 _tzname. Fixes the MSVC build. (Bug#9960)
5199 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5201 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5202 characters.

5205 !SYNC_INPUT. (Bug#11080)
5207 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5209 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5210 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5211 when fetching a multibyte character consumes more bytes than
5212 CHAR_BYTES returns, due to unification of CJK characters in
5213 string_char. (Bug#11073)
5215 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5217 * process.c (wait_reading_process_output): Handle pty disconnect
5218 by refraining from sending oneself a SIGCHLD (bug#10933).

5224 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5225 Mark string as coming from a prefix property.
5226 (handle_face_prop): Use default face for prefix strings (Bug#4281).

5237 Doc fixes.
5239 2012-03-20 Chong Yidong <cyd@gnu.org>
5241 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5242 to reflect default non-nil value of redisplay-dont-pause.
5244 2012-03-19 Kenichi Handa <handa@m17n.org>
5246 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5247 it fit in a valid range (Bug#11003).
5249 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5251 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5252 that is not from display property, accept the row as a "cursor
5253 row" if one of the string's character has a non-nil `cursor'
5254 property. Fixes cursor positioning when there are newlines in
5255 overlay strings, e.g. in icomplete.el. (Bug#11035)
5257 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5259 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5261 2012-03-12 Chong Yidong <cyd@gnu.org>
5263 * eval.c (inhibit_lisp_code): Rename from
5264 inhibit_window_configuration_change_hook; move from window.c.
5266 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5267 * window.c (run_window_configuration_change_hook)
5268 (syms_of_window): Callers changed.

5285 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5287 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5288 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5289 zero (Bug#10954).
5291 2012-03-03 Glenn Morris <rgm@gnu.org>
5293 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5295 2012-03-02 Eli Zaretskii <eliz@gnu.org>

5298 position past the first glyph_row that ends at ZV. (Bug#10902)
5299 (redisplay_window, next_element_from_string): Fix typos in
5300 comments.
5301 (redisplay_window): Pass to move_it_vertically the margin in
5302 pixels, not in screen lines.
5304 2012-03-02 Glenn Morris <rgm@gnu.org>
5306 * buffer.c (buffer-list-update-hook): Doc fix.
5308 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5310 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5311 push_it before setting up the iterator for the first overlay
5312 string, even if we have an empty string loaded.
5313 (next_overlay_string): If there's an empty string on the iterator
5314 stack, pop the stack. (Bug#10903)
5316 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5318 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5319 Suggested by Stefan Monnier in
5320 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5321 * alloc.c (widen_to_Lisp_Object): New static function.
5322 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5323 and widening them to Lisp_Objects. This would work even if
5324 USE_LSB_TAG is defined and wide integers are used, which might
5325 happen in a future version of Emacs.
5327 2012-02-25 Chong Yidong <cyd@gnu.org>
5329 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5330 Doc fix.
5332 * xselect.c (Fx_selection_exists_p): Doc fix.
5333 (x_clipboard_manager_save_all): Print an informative message
5334 before saving to clipboard manager.
5336 2012-02-24 Chong Yidong <cyd@gnu.org>
5338 * keyboard.c (process_special_events): Handle all X selection
5339 requests in kbd_buffer, not just the next one (Bug#8869).
5341 2012-02-23 Chong Yidong <cyd@gnu.org>
5343 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5344 call when setting menu-bar-lines and tool-bar-lines parameters.
5345 (unwind_create_frame_1): New helper function.
5347 * window.c (inhibit_window_configuration_change_hook): New var.
5348 (run_window_configuration_change_hook): Obey it.
5349 (syms_of_window): Initialize it.
5351 2012-02-22 Chong Yidong <cyd@gnu.org>
5353 * xterm.c (x_draw_image_relief): Add missing type check for
5354 Vtool_bar_button_margin (Bug#10743).
5356 2012-02-21 Chong Yidong <cyd@gnu.org>
5358 * fileio.c (Vfile_name_handler_alist): Doc fix.
5360 * buffer.c (Fget_file_buffer): Protect against invalid file
5361 handler return value.
5363 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5365 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5366 when computing $valmask.
5368 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5369 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5370 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5371 It's useless in that case, and it can cause problems on hosts
5372 that allocate halves of EMACS_INT values separately.
5373 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5374 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5375 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5376 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5377 it avoids undefined behavior on hosts where shifting right by more
5378 than the word width has undefined behavior.
5380 2012-02-19 Chong Yidong <cyd@gnu.org>
5382 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5383 (Funhandled_file_name_directory, Ffile_name_as_directory)
5384 (Fdirectory_file_name, Fexpand_file_name)
5385 (Fsubstitute_in_file_name): Protect against invalid file handler
5386 return values (Bug#10845).
5388 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5390 * .gdbinit (pitx): Fix incorrect references to fields of the

5400 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5402 2012-02-15 Chong Yidong <cyd@gnu.org>
5404 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5405 marked as special. Also, starting docstrings with * is obsolete.

5418 * keymap.c (Fsingle_key_description): Handle char ranges.
5420 2012-02-12 Chong Yidong <cyd@gnu.org>
5422 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5423 as that creates a dangerous corner case.
5425 * window.c (Fdelete_window_internal): Invalidate the mouse
5426 highlight (Bug#9904).
5428 2012-02-12 Glenn Morris <rgm@gnu.org>
5430 * xselect.c (Fx_own_selection_internal)
5431 (Fx_get_selection_internal, Fx_disown_selection_internal)
5432 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5433 * nsselect.m (Fx_own_selection_internal)
5434 (Fx_disown_selection_internal, Fx_selection_exists_p)
5435 (Fx_selection_owner_p, Fx_get_selection_internal):
5436 Sync docs and argument specs with the xselect.c versions.
5438 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5440 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

5458 2012-02-07 Chong Yidong <cyd@gnu.org>
5460 * buffer.c (Fbuffer_local_variables)
5461 (buffer_lisp_local_variables): Handle unbound vars correctly;
5462 don't let Qunbound leak into Lisp.
5464 2012-02-07 Glenn Morris <rgm@gnu.org>
5466 * image.c (Fimagemagick_types): Doc fix.
5468 * image.c (imagemagick-render-type): Change it from a lisp object
5469 to an integer. Move the doc here from the lisp manual.

5480 (pr): Use pp.
5482 2012-02-04 Chong Yidong <cyd@gnu.org>
5484 * nsterm.m: Declare a global (Bug#10694).
5486 2012-02-04 Eli Zaretskii <eliz@gnu.org>

5489 Include --enable-checking, if specified, in the return value.
5491 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5493 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5494 after rounding frame sizes. (Bug#9723)
5496 2012-02-04 Eli Zaretskii <eliz@gnu.org>

5499 before BEGV. (Bug#10696)
5501 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5503 Handle overflow when computing char display width (Bug#9496).
5504 * character.c (char_width): Return EMACS_INT, not int.
5505 (char_width, c_string_width): Check for overflow when
5506 computing the width; this is possible now that individual
5507 characters can have unbounded width. Problem introduced
5508 by merge from Emacs 23 on 2012-01-19.
5510 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

5525 2012-02-02 Kenichi Handa <handa@m17n.org>
5527 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5528 0, do not call append_composite_glyph.

5532 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5533 NULL (Bug#6988).

5539 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5540 first 2 arguments are identical. This makes inserting large
5541 output from a subprocess an order of magnitude faster on
5542 MS-Windows, where all sbrk'ed memory is always contiguous.
5544 2012-01-31 Glenn Morris <rgm@gnu.org>
5546 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

5582 2012-01-21 Chong Yidong <cyd@gnu.org>

5608 window parameters.
5610 2012-01-14 Eli Zaretskii <eliz@gnu.org>
5612 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid

5625 before a R2L line.
5627 2012-01-11 Glenn Morris <rgm@gnu.org>
5629 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
5630 from load-path also when installation-directory is nil. (Bug#10208)
5632 2012-01-10 Glenn Morris <rgm@gnu.org>
5634 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

5637 Update template values to be closer to their typical values these days.
5639 2012-01-09 Eli Zaretskii <eliz@gnu.org>
5641 * xdisp.c (rows_from_pos_range): Accept additional argument
5642 DISP_STRING, and accept any glyph in a row whose object is that
5643 string as eligible for mouse highlight. Fixes mouse highlight of
5644 display strings from overlays. (Bug#10464)
5646 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
5648 emacs: fix an auto-save permissions race condition (Bug#10400)
5649 * fileio.c (auto_saving_dir_umask): New static var.
5650 (Fmake_directory_internal): Use it.
5651 (do_auto_save_make_dir): Set it, instead of invoking chmod after
5652 creating the directory. The old code temporarily assigns
5653 too-generous permissions to the directory.
5654 (do_auto_save_eh): Clear it.
5655 (Fdo_auto_save): Catch all errors, not just file errors, so
5656 that the var is always cleared.

5660 * search.c (scan_buffer): Pass character positions to
5661 know_region_cache, not byte positions. (Bug#6540)

5696 * coding.c (Fdefine_coding_system_internal): Make an utf-8 base
5697 coding-system ASCII compatible only when it does not produce BOM
5698 on encoding (Bug#10383).
5700 2011-12-26 Jan Djärv <jan.h.d@swipnet.se>
5702 * xmenu.c (x_menu_wait_for_event): Use xg_select for Gtk3 so menus
5703 can scroll.

6043 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6044 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

6158 Otherwise, valgrind does not work on some platforms.
6159 Problem reported by Andreas Schwab in
6160 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6161 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6162 is set, removing the need for VIRT_ADDRESS_VARIES.
6163 (PURE_P): Use a more-efficient implementation that needs just one
6164 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6165 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6166 to 4 (xorl, subq, cmpq, setbe).
6167 * alloc.c (pure): Always extern now, since that's the
6168 VIRT_ADDR_VARIES behavior.
6169 (PURE_POINTER_P): Use a single comparison, not two, for
6170 consistency with the new puresize.h.
6171 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6172 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6257 * xdisp.c (display_line): Move the call to
6258 highlight_trailing_whitespace before the call to
6259 compute_line_metrics, since the latter needs to see the final

6261 Fixes assertion violations in row_equal_p. (Bug#10035)
6263 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6265 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6641 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6642 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6643 (g_b_init_get_glyph_outline_w): New static variables.
6644 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6645 (GetGlyphOutlineW_Proc): New typedefs.
6646 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6647 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6648 New functions.
6649 (w32font_open_internal, compute_metrics):
6650 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6651 instead of calling the "wide" APIs directly.
6653 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6655 * w32.h (syms_of_w32font): Add prototype.
6657 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6659 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6660 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6661 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6662 (Fmove_to_window_line): Doc fix.
6664 2011-10-27 Chong Yidong <cyd@gnu.org>
6666 * process.c (make_process): Set gnutls_state to NULL.
6668 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6669 non-NULL, regardless of GNUTLS_INITSTAGE.
6670 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6671 an error. Set process slots as soon as we allocate them.
6673 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6675 2011-10-27 Chong Yidong <cyd@gnu.org>
6677 * gnutls.c (emacs_gnutls_deinit): New function.
6678 Deallocate credentials structures as well as calling gnutls_deinit.
6679 (Fgnutls_deinit, Fgnutls_boot): Use it.
6681 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6682 (deactivate_process): Call emacs_gnutls_deinit.
6684 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6686 * image.c (x_create_x_image_and_pixmap):
6687 * w32.c (sys_rename, w32_delayed_load):
6688 * w32font.c (fill_in_logfont):
6689 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6691 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6693 * w32fns.c (w32_default_color_map): New function,
6694 extracted from Fw32_default_color_map.
6695 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6697 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6699 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6701 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6703 * keyboard.c (test_undefined): New function (bug#9751).
6704 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6706 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6708 * sysdep.c (init_sys_modes): Fix the check for the controlling
6709 terminal (Bug#6649).
6711 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6713 * dispextern.h (struct bidi_it): New member next_en_type.
6715 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6716 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6717 current character, check also for next_en_type being WEAK_EN.
6718 (bidi_resolve_weak): Don't enter the expensive loop if the current
6719 position is before next_en_pos. Record the bidi type of the first
6720 non-ET, non-BN character we find, in addition to its position.
6721 (bidi_level_of_next_char): Invalidate next_en_type when
6722 next_en_pos is over-stepped.
6724 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6726 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6727 * editfns.c: Rewrite current-time-zone so that it invokes
6728 the equivalent of (format-time-string "%Z") to get the time zone name.
6729 This fixes a bug when the time zone name contains characters that
6730 need converting from the system time locale to Emacs internal format.
6731 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6732 that patch fixed format-time-string to do the conversion, but
6733 I forgot to fix current-time-zone.
6734 (format_time_string): New function, containing most of
6735 what Fformat_time_string used to contain.
6736 (Fformat_time_string): Rewrite in terms of format_time_string.
6737 This doesn't change this function's behavior.
6738 (current-time-zone): Rewrite to use format_time_string.
6739 This fixes the bug reported by Michael Schierl in
6740 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6741 Jason Rumney's 2007-06-07 change worked around this bug, but
6742 didn't fix it.
6743 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6745 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6747 * xdisp.c (start_display): If the character at POS is displayed
6748 via a display vector, reset IT->current.dpvec_index to zero.
6749 (try_window_reusing_current_matrix): If a line ends in a display
6750 vector or the next line starts in a display vector, continue
6751 redrawing the window even though the character position of
6752 start_row was reached.
6753 (Bug#9771, part 2)
6755 2011-10-18 Chong Yidong <cyd@gnu.org>
6757 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6758 with nobreak-char-display too.
6760 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6762 Fix part 3 of bug#9771.
6763 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6764 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6765 non-neutral characters if the current character is a paragraph
6766 separator (a.k.a. Newline). This avoids running the same
6767 expensive loop twice, once when we consume the preceding newline
6768 and the other time when the line actually needs to be displayed.
6769 Avoid the loop when we see neutrals on the base embedding level
6770 following a character whose directionality is the same as the
6771 paragraph's. This avoids running the expensive loop when a line
6772 ends in a long sequence of neutrals, like control characters.
6773 Add assertion against STRONG_AL type. Slightly rearrange code
6774 that determines the type of a neutral given the first non-neutral
6775 that follows it.
6776 (bidi_level_of_next_char): Set next_en_pos to zero when
6777 invalidating its info.
6779 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6781 * xdisp.c (push_display_prop): Determine whether to record string
6782 or buffer position by IT->string, not by IT->method. Allow
6783 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6784 (move_it_vertically_backward): Don't look for character position
6785 immediately after the newline when in a continuation line.
6786 (Bug#9771, part 1)
6788 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6790 * window.c (coordinates_in_window): Rewrite and delabelize
6791 vertical border check. (Bug#5357) (Bug#9618)
6793 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6795 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6796 errors in XSetWindowBorder (bug#9310).
6798 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6800 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6801 avoid crash when xmalloc overrun checking is enabled.
6803 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6805 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6806 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6807 cursor motion with <left> and <right> arrow keys.
6809 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6810 some callers set that themselves.
6812 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6814 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6815 display string and the previous row comes from the same string and
6816 is empty. (Bug#9739) (Bug#9738)
6818 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6820 * doc.c (get_doc_string): Encode file name (bug#9735).
6822 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6824 * bidi.c (bidi_level_of_next_char):
6825 * xdisp.c (get_visually_first_element): Remove old incorrect
6826 comments regarding the Unicode Line Separator character.
6828 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6830 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6832 * alloc.c (Fgc_status): Do not access beyond zombies array
6833 boundary if nzombies > MAX_ZOMBIES.
6834 * alloc.c (dump_zombies): Add missing format specifier.
6836 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6838 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6839 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6841 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6842 Some packages use them to denote characters with modifiers.
6844 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6846 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6847 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6848 matching a pp-number. Rename parameter var to var1.
6850 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6852 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6854 2011-10-08 Glenn Morris <rgm@gnu.org>
6856 * callint.c (Fcall_interactively): Give a more explicit error for the
6857 'c' case with a non-character input. (Bug#8479)
6859 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6861 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6862 lines.
6863 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6864 lines that are hscrolled on the left.
6866 * dispnew.c (buffer_posn_from_coords): Account for a possible
6867 presence of header-line. (Bug#4426)
6869 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6871 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6872 Don't advertise functionality which we discourage or doesn't work.
6874 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6876 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6877 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6878 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6879 this makes Emacs dump core during garbage collection on rare
6880 occasions. sizeof is obviously inferior to offsetof here, so
6881 stick with offsetof.
6882 (GC_POINTER_ALIGNMENT): New macro.
6883 (mark_memory): Omit 3rd (offset) arg; caller changed.
6884 Don't assume EMACS_INT alignment is the same as pointer alignment.
6886 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6888 * keyboard.c (read_key_sequence_remapped): New var.
6889 (read_key_sequence): Compute remapping in the right buffer.
6890 (command_loop_1): Use read_key_sequence's remapping directly.
6892 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6894 * dired.c (file_name_completion): Don't expand file name.
6895 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6896 before checking file name handler.
6898 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6899 they've been requested explicitly (bug#9591).
6901 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6903 * keymap.c (Fsingle_key_description): Use make_specified_string
6904 instead of build_string to build string from push_key_description.
6905 (Bug#5193)
6907 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6909 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6910 This fixes a Y2038 bug on 64-bit hosts.
6911 * buffer.c (reset_buffer):
6912 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6913 (Fclear_buffer_auto_save_failure):
6914 Use 0, not -1, to represent an unset failure time, since time_t
6915 might not be signed.
6917 Remove dependency on glibc malloc internals.
6918 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6919 Move back here from lisp.h, but with their new implementations.
6920 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6921 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6922 * charset.c (charset_table_init): New static var.
6923 (syms_of_charset): Use it instead of xmalloc. This removes a
6924 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6925 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6926 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6927 Move back to alloc.c.
6928 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6929 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6931 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6933 * nsterm.m (windowDidResize): Call x_set_window_size only when
6934 ns_in_resize is true. Otherwise set pixelwidth/height and
6935 call change_frame_size (Bug#9628).
6937 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6939 Port --enable-checking=all to Fedora 14 x86-64.
6940 * charset.c (syms_of_charset): Also account for glibc malloc's
6941 internal overhead when calculating the initial malloc maximum.
6943 Port --enable-checking=all to Fedora 14 x86.
6944 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6945 Move to lisp.h.
6946 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6947 (overrun_check_realloc, overrun_check_free):
6948 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6949 That way, xmalloc returns a properly-aligned pointer even if
6950 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6951 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6952 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6953 into account when calculating the initial malloc maximum.
6954 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6955 Move here from alloc.c, so that charset.c can use it too.
6956 Properly align; the old code wasn't right for common 32-bit hosts
6957 when configured with --enable-checking=all.
6958 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6959 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6961 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6963 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6964 use EDOM.
6966 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6968 * xdisp.c (compute_display_string_end): If there's no display
6969 string at CHARPOS, return -1.
6971 * bidi.c (bidi_fetch_char): When compute_display_string_end
6972 returns a negative value, treat the character as a normal
6973 character not covered by a display string. (Bug#9624)
6975 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6977 * lread.c (Fread_from_string): Fix typo in docstring.
6979 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6981 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6982 newline, reseat the iterator instead of bidi-iterating there one
6983 character at a time. (Bug#9610)
6984 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6985 TO_CHARPOS if the bidi iterator is at base embedding level.
6987 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6989 * lread.c (readevalloop): Use correct code for NBSP.
6990 (read1): Likewise. (Bug#9608)
6992 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6994 * dbusbind.c (Fdbus_register_signal): When service is not
6995 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6997 2011-09-25 Glenn Morris <rgm@gnu.org>
6999 * buffer.c (truncate-lines): Doc fix.
7001 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7003 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7004 (Fset_window_next_buffers): Doc fix.
7006 2011-09-24 Glenn Morris <rgm@gnu.org>
7008 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7010 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7012 Fix minor problems found by static checking.
7013 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7014 * indent.c (Fvertical_motion): Fix == vs = typo.
7016 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7018 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7019 Default value is now t. Doc fix.
7021 * indent.c (Fvertical_motion): Compute and apply the overshoot
7022 logic when moving up, not only when moving down. Fix the
7023 confusing name and values of the it_overshoot_expected variable;
7024 logic changes accordingly. (Bug#9254) (Bug#9549)
7026 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7027 CHARPOS is covered by a display string which includes newlines.
7028 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7029 is covered by a display string with embedded newlines.
7031 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7033 * dbusbind.c (Fdbus_register_signal): Add match rule to
7034 Vdbus_registered_objects_table. (Bug#9581)
7035 (Fdbus_register_method, Vdbus_registered_objects_table):
7036 Fix docstring.
7038 2011-09-24 Jim Meyering <meyering@redhat.com>
7040 do not ignore write error for any output size
7041 The previous change was incomplete.
7042 While it makes emacs --batch detect the vast majority of stdout
7043 write failures, errors were still ignored whenever the output size is
7044 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7045 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7046 && echo FAIL: ignored write error
7047 FAIL: ignored write error
7048 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7049 && echo FAIL: ignored write error
7050 FAIL: ignored write error
7051 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7053 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7055 * emacs.c (Fkill_emacs): In noninteractive mode exit
7056 non-successfully if a write error occurred on stdout. (Bug#9574)
7058 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7060 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7061 the xassert test.
7063 * dispextern.h (struct it): Update the comment documenting what
7064 can it->OBJECT be.
7066 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7068 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7069 a display string, extend search for cursor position to end of row.
7070 (find_row_edges): If the row ends in a newline from a display
7071 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7072 Handle the case of a display string with multiple newlines.
7073 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7074 non-empty line. Fixes confusing cursor motion with arrow keys at
7075 the beginning of a line that starts with whitespace.
7077 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7079 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7080 (bug#9493).
7082 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7084 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7085 boolean (Bug#9154).
7087 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7089 * xdisp.c (display_line): Record maximum and minimum buffer
7090 positions even if no glyphs were produced (e.g., by a zero-width
7091 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7092 buffer positions that will be removed from the glyph row because
7093 they don't fit.
7094 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7095 column is beyond frame width: don't subtract 1 "pixel" when
7096 computing width of the stretch.
7097 (reseat_at_next_visible_line_start): Undo the change made on
7098 2011-09-17 that saved paragraph information and restored it after
7099 the call to `reseat'. (Bug#9545)
7101 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7103 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7104 and turn window cursor on if cleared (Bug#9415).
7106 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7108 * search.c (boyer_moore): Take unibyte characters from pattern
7109 literally. (Bug#9458)
7111 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7113 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7115 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7117 Fix minor problem found by static checking.
7118 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7119 initialized, to pacify gcc -Wuninitialized.
7121 * fileio.c: Report proper errno when syscall falls.
7122 (Finsert_file_contents): Save and restore errno,
7123 so that report_file_error outputs the correct diagnostic.
7124 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7126 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7128 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7130 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7132 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7133 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7135 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7137 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7138 about the current paragraph and restore it after the call to reseat.
7140 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7141 (bidi_find_paragraph_start): Search back for paragraph beginning
7142 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7143 (bidi_move_to_visually_next): Only trigger paragraph-related
7144 computations when the last character is a newline or at EOB, not
7145 just any NEUTRAL_B. (Bug#9470)
7147 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7148 truncated lines if point is covered by a display string. (Bug#9524)
7150 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7152 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7153 (cons_to_x_long): New function.
7154 (lisp_data_to_selection_data): Use it. Correct the test for
7155 short-versus-long data; it was negated. Break out of vector
7156 loop, for efficiency, when a long datum is discovered.
7158 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7160 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7162 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7164 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7165 GCC PR/17406) by declaring this function with external scope.
7167 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7169 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7170 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7172 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7174 * editfns.c (Fformat): Correctly handle text properties on "%%".
7176 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7178 * xterm.c (x_draw_composite_glyph_string_foreground):
7179 * w32term.c (x_draw_composite_glyph_string_foreground):
7180 * term.c (encode_terminal_code):
7181 * composite.c (composition_update_it, get_composition_id):
7182 * xdisp.c (get_next_display_element)
7183 (fill_composite_glyph_string): Add comments about special meaning
7184 of TAB characters in a composition.
7186 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7188 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7189 This occurs when processing a multibyte format.
7190 Problem reported by Wolfgang Jenker.
7192 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7194 * xdisp.c (try_cursor_movement): Only check for exact match if
7195 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7197 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7199 Remove unused external symbols.
7200 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7201 * xdisp.c (calc_pixel_width_or_height): Now static.
7202 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7203 * indent.c (check_display_width):
7204 * w32term.c: Fix comment to match code.
7205 * xterm.c, xterm.h (x_catching_errors): Remove.
7207 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7209 * xselect.c: Use signed conversions more consistently (Bug#9498).
7210 (selection_data_to_lisp_data): Assume incoming selection data are
7211 signed integers, not unsigned. This is to be consistent with
7212 outgoing selection data, which was modified to use signed integers
7213 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7214 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7215 expects long, not unsigned long.
7217 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7219 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7220 computation of loop end. Reported by Johan Bockgård
7221 <bojohan@gnu.org>.
7223 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7225 * frame.c (Fother_visible_frames_p): Function deleted.
7227 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7229 * indent.c (compute_motion): Process display vector front to back
7230 rather than the other way around. (Bug#2496)
7232 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7234 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7236 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7238 * minibuf.c (Fread_from_minibuffer): Doc fix.
7240 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7242 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7243 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7245 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7247 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7248 value for non-existent files.
7250 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7252 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7253 set its "size" to -1. This will set the modtime_size field of
7254 the corresponding buffer to -1, which is what
7255 verify-visited-file-modtime expects for files that do not exist.
7256 (Bug#9139)
7258 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7260 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7261 here ...
7262 * lisp.h: ... from here. push_key_description is no longer
7263 defined in keyboard.c, so its declaration should not be in
7264 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7265 logically belongs with push_key_description.
7267 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7269 * buffer.h: Include <sys/types.h> instead of <time.h>.
7270 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7271 Problem reported by Herbert J. Skuhra.
7273 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7275 * xml.c (parse_region): Make the parsing work for
7276 non-comment-starting XML files again (bug#9144).
7278 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7280 * image.c (gif_load): Fix calculation of bottom and right corner.
7281 (Bug#9468)
7283 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7285 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7286 redisplay in small windows.
7288 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7290 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7292 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7294 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7295 Operate on live windows only.
7297 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7299 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7301 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7303 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7304 only under bidi iteration.
7306 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7308 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7310 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7312 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7313 Without this fix, the command to link temacs failed due to an
7314 undefined symbol __builtin_isnan. This is because
7315 /usr/include/iso/math_c99.h #defines isnan(x) to
7316 __builtin_isnan(x), but the bundled gcc, which identifies itself
7317 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7318 a __builtin_isnan.
7319 * floatfns.c (isnan): #undef, and then #define to a clone of
7320 what's in data.c.
7321 (Fisnan): Always define, since it's always available now.
7322 (syms_of_floatfns): Always define isnan at the Lisp level.
7324 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7326 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7328 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7330 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7331 The previous code assumed that file offsets (off_t values) fit in
7332 EMACS_INT variables, which is not true on typical 32-bit hosts.
7333 The code messed up by falsely reporting buffer overflow in cases
7334 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7335 when "big" contains more than 2**29 bytes, even though this
7336 inserts just one byte and does not overflow the buffer.
7337 (Finsert_file_contents): Store file offsets as off_t
7338 values, not as EMACS_INT values. Check for overflow when
7339 converting between EMACS_INT and off_t. When checking for
7340 buffer overflow or for overlap, take the offsets into account.
7341 Don't use EMACS_INT for small values where int suffices.
7342 When checking for overlap, fix a typo: ZV was used where
7343 ZV_BYTE was intended.
7344 (Fwrite_region): Don't assume off_t fits into 'long'.
7345 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7347 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7349 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7351 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7353 sprintf-related integer and memory overflow issues (Bug#9412).
7355 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7356 (esprintf, exprintf, evxprintf): New functions.
7357 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7358 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7359 (modify_event_symbol): Do not assume that the length of
7360 name_alist_or_stem is safe to alloca and fits in int.
7361 (Fexecute_extended_command): Likewise for function name and binding.
7362 (Frecursion_depth): Wrap around reliably on integer overflow.
7363 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7364 since some callers pass EMACS_INT values.
7365 (Fsingle_key_description): Don't crash if symbol name contains more
7366 than MAX_ALLOCA bytes.
7367 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7368 (get_minibuffer): Arg is now EMACS_INT, not int.
7369 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7370 (esprintf, exprintf, evxprintf): New decls.
7371 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7373 * dbusbind.c (signature_cat): New function.
7374 (xd_signature, Fdbus_register_signal):
7375 Do not overrun buffer; instead, report string overflow.
7377 * dispnew.c (add_window_display_history): Don't overrun buffer.
7378 Truncate instead; this is OK since it's just a log.
7380 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7381 even if the time zone offset is outlandishly large.
7382 Don't mishandle offset == INT_MIN.
7384 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7385 when creating daemon; the previous buffer-overflow check was incorrect.
7387 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7388 which has the guts of the old verror function.
7390 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7391 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7393 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7394 (font_unparse_xlfd): Don't blindly alloca long strings.
7395 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7396 fits in int, when using sprintf. Use single snprintf to count
7397 length of string rather than counting it via multiple sprintfs;
7398 that's simpler and more reliable.
7399 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7400 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7401 sprintf, in case result does not fit in int.
7403 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7404 (fontset_from_font): Print it.
7406 * frame.c (tty_frame_count): Now printmax_t, not int.
7407 (make_terminal_frame, set_term_frame_name): Print it.
7408 (x_report_frame_params): In X, window IDs are unsigned long,
7409 not signed long, so print them as unsigned.
7410 (validate_x_resource_name): Check for implausibly long names,
7411 and don't assume name length fits in 'int'.
7412 (x_get_resource_string): Don't blindly alloca invocation name;
7413 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7414 not fit in int.
7416 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7417 (xg_check_special_colors, xg_set_geometry):
7418 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7420 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7421 Use esprintf, not sprintf, in case result does not fit in int.
7423 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7424 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7425 it as a large positive number.
7426 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7427 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7429 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7430 in case result does not fit in int.
7432 * print.c (float_to_string): Detect width overflow more reliably.
7433 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7434 buffer overrun. Don't assume list length fits in 'int'. Treat
7435 print length of 0 as 0, not as infinity; to be consistent with other
7436 uses of print length in this function. Don't overflow print length
7437 index. Don't assume hash table size fits in 'long', or that
7438 vectorlike size fits in 'unsigned long'.
7440 * process.c (make_process): Use printmax_t, not int, to format
7441 process-name gensyms.
7443 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7445 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7446 to avoid potential buffer overrun.
7448 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7449 if X resource line is longer than 512 bytes.
7451 * xfns.c (x_window): Make sprintf buffer a bit bigger
7452 to avoid potential buffer overrun.
7454 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7456 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7458 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7460 Integer overflow fixes for scrolling, etc.
7461 Without these, Emacs silently mishandles large integers sometimes.
7462 For example, "C-u 4294967297 M-x recenter" was treated as if
7463 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7465 * xdisp.c (try_window_id): Check Emacs fixnum range before
7466 converting to 'int'.
7468 * window.c (window_scroll_line_based, Frecenter):
7469 Check that an Emacs fixnum is in range before assigning it to 'int'.
7470 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7471 values converted from Emacs fixnums.
7472 (Frecenter): Don't wrap around a line count if it is out of 'int'
7473 range; instead, treat it as an extreme value.
7474 (Fset_window_configuration, compare_window_configurations):
7475 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7477 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7478 that can exceed INT_MAX. Check that EMACS_INT value is in range
7479 before assigning it to the (possibly-narrower) index.
7480 (match_limit): Don't assume that a fixnum can fit in 'int'.
7482 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7483 exceed INT_MAX.
7485 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7486 (Fvertical_motion): Don't wrap around LINES values that don't fit
7487 in 'int'. Instead, treat them as extreme values. This is good
7488 enough for windows, which can't have more than INT_MAX lines anyway.
7490 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7492 * Require libxml/parser.h to avoid compilation warning.
7494 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7496 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7497 since this reportedly can destroy thread storage.
7499 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7501 * syntax.c (find_defun_start): Update all cache variables if
7502 exiting early (Bug#9401).
7504 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7506 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7508 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7509 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7510 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7512 * term.c (tty_append_glyph): New function.
7513 (produce_stretch_glyph): Static function and its prototype deleted.
7515 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7516 Add prototypes.
7518 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7520 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7521 when checking :margin (Bug#9390).
7522 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7523 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7524 so that the name doesn't mislead. All uses changed.
7526 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7528 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7529 set_tty_hooks.
7531 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7533 * xdisp.c (move_it_to): Don't bail out early when reaching
7534 position beyond to_charpos, if we are scanning backwards.
7535 (move_it_vertically_backward): When DY == 0, make sure we get to
7536 the first character in the line after the newline.
7538 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7540 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7541 (ccl_driver): Do not generate an out-of-range pointer.
7542 (Fccl_execute_on_string): Remove unnecessary check for
7543 integer overflow, noted by Stefan Monnier in
7544 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7545 Remove a FIXME that didn't need fixing.
7546 Simplify the newly-introduced buffer reallocation code.
7548 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7550 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7552 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7554 Integer and memory overflow issues (Bug#9196).
7556 * doc.c (get_doc_string): Rework so that
7557 get_doc_string_buffer_size is the actual buffer size, rather than
7558 being 1 less than the actual buffer size; this makes xpalloc more
7559 convenient.
7561 * image.c (x_allocate_bitmap_record, cache_image):
7562 * xselect.c (Fx_register_dnd_atom):
7563 Simplify previous changes by using xpalloc.
7565 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,

7570 (charset_compare): Don't overflow if priorities differ greatly.
7571 (Fsort_charsets): Don't assume list length fits in int.
7572 Check for size-calculation overflow when allocating sort data.
7573 (syms_of_charset): Allocate an initial charset table that is
7574 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7576 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7578 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7579 The actual value is always <= INT_MAX, and leaving it unsigned made
7580 overflow checking harder.
7582 * dispextern.h (struct glyph_matrix.rows_allocated)
7583 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7584 with xpalloc. The values are still always <= INT_MAX.

7593 (set_cache_region, invalidate_region_cache)
7594 (revalidate_region_cache, know_region_cache, region_cache_forward)
7595 (region_cache_backward, pp_cache):
7596 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7597 so that ptrdiff_t * can be passed to xpalloc.
7598 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7599 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7600 (pp_cache): Don't assume cache_len fits in int.
7601 * region-cache.h: Adjust extern decls to match.

7614 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7615 (overlay_strings):
7616 Don't update size of array until after memory allocation succeeds,
7617 because xmalloc/xrealloc may not return.
7618 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7619 now that we have proper integer overflow checking.
7620 (record_overlay_string, overlay_strings): Catch overflows when
7621 calculating size of overlay_str_buf.
7623 * callproc.c (Fcall_process): Check for size overflow when
7624 calculating size of args2.
7625 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7626 Normally we prefer signed values, but sticking with ptrdiff_t would
7627 require adding more-complicated checks.
7629 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7630 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7631 Redo buffer-overflow calculations to avoid integer overflow.
7632 Add a FIXME comment where memory seems to be over-allocated.
7634 * character.c (Fstring): Check for size-calculation overflow.
7636 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7637 unnecessary integer overflow. Check for size overflow.

7666 fits in int.
7667 (message_length): Now ptrdiff_t, not int.
7668 (Fmessage_box): Don't update size until allocation succeeds.
7669 Don't assume message length fits in int.
7670 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7672 * emacs.c (main): Do not reallocate argv, since there is a null at
7673 the end that can be overwritten, and this way there's no need to
7674 worry about size-calculation overflow.
7675 (sort_args): Check for size-calculation overflow.
7677 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7678 alloc succeeds.

7681 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7682 (x_set_scroll_bar_width, x_figure_window_size):
7683 Check for integer overflow.
7684 (x_set_alpha): Do not assume XINT fits in int.
7686 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7687 This is for the members text_lines, text_cols, total_lines, total_cols,
7688 where the system imposes an 'int' limit.
7690 * fringe.c (Fdefine_fringe_bitmap):
7691 Don't update size until alloc works.
7693 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7694 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7696 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7697 Check for size-calculation overflow.
7698 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7699 do, as we prefer signed integers.
7700 (id_to_widget.max_size, id_to_widget.used)
7701 (xg_store_widget_in_map, xg_remove_widget_from_map)
7702 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7703 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7704 Use and return ptrdiff_t, not int.
7705 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7706 * gtkutil.h: Change prototypes to match the above.
7708 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7709 are duplicate now that they've been promoted to lisp.h.
7710 (x_allocate_bitmap_record, x_alloc_image_color)
7711 (make_image_cache, cache_image, xpm_load):

7755 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7756 for command line length. Do not attempt to address one before the
7757 beginning of an array, as that's not portable.

7786 (Finternal_make_lisp_face, cache_face):
7787 Check for size calculation overflow.
7788 (cache_face): Treat size calculation overflows as if they were

7792 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7793 sizes, since they can exceed INT_MAX in size. Check for size

7803 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7804 (X_LONG_MIN): New macros.
7805 Use them to make the following changes clearer.
7806 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7807 This change doesn't affect the value now, but it may help remind
7808 future maintainers not to raise the value too much later.
7809 (SELECTION_QUANTUM): Remove, replacing with ...
7810 (selection_quantum): ... new function, which avoids overflow.
7811 All uses changed.
7812 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7813 assumption that selection length fits in 'int'.

7821 Redo calculations to avoid overflow.
7822 (x_reply_selection_request): When sending hint, ceiling it at

7824 something.
7825 (x_get_window_property, receive_incremental_selection)
7826 (lisp_data_to_selection_data, x_property_data_to_lisp):

7830 Don't store size until memory allocation succeeds.
7831 (x_get_window_property): Plug memory leak on memory exhaustion.
7832 Don't double-block input; malloc is safe here. Don't assume 2**34
7833 - 4 fits in unsigned long. Add an xassert to check
7834 XGetWindowProperty overflow. Be more careful about overflow
7835 calculations, and distinguish size from memory overflow better.
7836 (receive_incremental_selection): When tracing, don't assume
7837 unsigned int is less than INT_MAX.
7838 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

7841 in the range -65535 through -1 fit in an X unsigned short.
7842 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7843 result parameters unless successful. Rely on cons_to_unsigned
7844 to report problems with elements; the old code wasn't right anyway.
7845 (x_check_property_data): Check for int overflow; we cannot use
7846 a wider type due to X limits.
7847 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7879 * lisp.h (hash_lookup, hash_put):
7880 * minibuf.c (Ftest_completion):
7881 Use ptrdiff_t for hash table indexes, not int (which is too
7882 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7883 32-bit --with-wide-int hosts).
7885 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7886 Add a FIXME comment about memory leaks.
7887 (syms_of_charset): Don't assume xmalloc returns.
7889 Don't assume that stated character widths fit in int.

7893 Use sanitize_char_width to avoid undefined and/or bad behavior
7894 with outlandish widths.

7918 ptrdiff_t and size_t limits.
7920 * keyboard.c: Overflow, signedness and related fixes.
7921 (make_lispy_movement): Use same integer type in forward decl
7922 that is used in the definition.
7923 (read_key_sequence, keyremap_step):
7924 Change bufsize argument back to int, undoing my 2011-03-30 change.
7925 We prefer signed types, and int is wide enough here.
7926 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7927 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7928 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7929 length, not size_t. Use ptrdiff_t for index, not int.
7930 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7931 possibility of integer overflow.
7933 Overflow, signedness and related fixes for images.

7957 since parse_image_check makes sure they fit into int.
7958 (png_load, gif_load, svg_load_image):
7959 Prefer int to unsigned where either will do.
7960 (tiff_handler): New function, combining the cores of the
7961 old tiff_error_handler and tiff_warning_handler.
7962 This function is rewritten to use vsnprintf and thereby avoid
7963 stack buffer overflows. It uses only the features of vsnprintf
7964 that are common to both POSIX and native Microsoft.
7965 (tiff_error_handler, tiff_warning_handler): Use it.
7966 (tiff_load, gif_load, imagemagick_load_image):
7967 Don't assume :index value fits in 'int'.
7968 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7969 (imagemagick_load_image): Check that crop parameters fit into
7970 the integer types that MagickCropImage accepts. Don't assume
7971 Vimagemagick_render_type has a nonnegative value. Don't assume
7972 size_t fits in 'long'.
7973 (gs_load): Use printmax_t to print the widest integers possible.
7974 Check for integer overflow when computing image height and width.
7976 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7978 * xdisp.c (redisplay_window): Don't force window start if point
7979 will be invisible in the resulting window. (Bug#9324)
7981 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7983 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when

7986 handle_single_display_spec, not just 1 or zero.
7987 (handle_single_display_spec): If the display spec is of the form
7988 `(space ...)', and specifies display in the text area, return 2
7989 rather than 1.
7990 (try_cursor_movement): Check for the need to scroll more
7991 accurately, and prefer exact match for point under bidi.
7992 Don't advance `row' beyond the last row of the window.
7994 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7995 into disp_prop; all users changed.
7997 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7998 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character

8009 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8010 buffers, return left-to-right.
8011 (set_cursor_from_row): Consider candidate row a win if its glyph
8012 represents a newline and point is on that newline. Fixes cursor
8013 positioning on the newline at EOL of R2L text within L2R
8014 paragraph, and vice versa.
8015 (try_cursor_movement): Check continued rows, in addition to
8016 continuation rows. Fixes unwarranted scroll when point enters a
8017 continued line of R2L text within an L2R paragraph, or vice versa.
8018 (cursor_row_p): Consider the case of point being equal to
8019 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

8041 extra slot even if the purpose is char-code-property-table.
8043 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8045 * xdisp.c (redisplay_window): When computing centering_position,
8046 account for the height of the header line. (Bug#8874)
8048 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8049 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8050 candidate is selected by the mouse, and that candidate has a
8051 composed character under the mouse.
8053 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8054 coordinates reported by pos-visible-in-window-p for a composed
8055 character in column zero.
8057 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

8061 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8063 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8064 consider it a hit if to_charpos is anywhere in the range of the
8065 composed buffer positions.
8067 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8069 * image.c (gif_load): Don't assume that each subimage has the same
8070 dimensions as the base image. Handle disposal method that is
8071 "undefined" by the gif spec (Bug#9335).
8073 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8075 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8078 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8080 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8081 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8082 from an Org mode buffer to a Speedbar frame.
8084 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8085 a composition, take its buffer position from IT->cmp_it.charpos.
8086 Fixes cursor positioning at the beginning of a line that begins
8087 with a composed character.
8089 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8091 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8092 character bidirectional type, use STRONG_L instead. Fixes crashes
8093 in a buffer produced by `describe-categories'.
8095 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8096 members before the level stack, so they would be saved and
8097 restored when copying iterator state. Fixes incorrect reordering
8098 around TABs covered by display properties.
8100 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8102 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8107 (internal_condition_case_2, internal_condition_case_n):
8108 Remove unnecessary aborts (Bug#9081).
8110 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8112 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8113 has no `load' handler, try opening the file locally. (Bug#9311)
8115 2011-08-16 Ken Brown <kbrown@cornell.edu>
8117 * gmalloc.c: Expand comment.
8119 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8121 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate

8172 * xdisp.c (move_it_in_display_line_to): Don't invoke
8173 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8174 ppos_it. Fixes vertical cursor motion when line beginning is
8175 covered by an image. (Bug#9296)
8177 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8179 * nsterm.h (ns_run_ascript): Declare.

8186 the event loop. Get status from as_status (Bug#7276).
8188 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8189 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8190 the event loop (Bug#7276).
8192 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8194 * gnutls.c (QCgnutls_bootprop_priority)

8216 (Fnetwork_interface_list): Allocate in increments of bytes instead
8217 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting

8222 Get hardware address with getifaddrs if available.
8224 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8226 * xdisp.c (iterate_out_of_display_property): xassert that
8227 IT->position is set to within IT->object's boundaries. Break from
8228 the loop as soon as EOB is reached; avoids infloops in redisplay
8229 when IT->position is set up wrongly due to some bug.
8230 Set IT->current to match the bidi iterator unconditionally.
8231 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8232 entry. Force push_it to save on the stack the current
8233 buffer/string position, to be restored by pop_it. Fix flags in
8234 the iterator structure wrt the object coming from a display
8235 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8236 properties. (Bug#9284)
8238 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8240 * fontset.c (fontset_get_font_group): Add proper type checks.

8255 properties and overlays.
8257 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8259 * editfns.c (Fset_time_zone_rule): Document relationship with the

8268 restore_point_unwind (Bug#5984).
8270 2011-08-07 Juri Linkov <juri@jurta.org>
8272 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8273 to show the arg `TIME' instead of `TIMEVAL'.
8275 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8277 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8278 display property strides EOL and includes a newline, as in
8279 longlines-mode. (Bug#9254)
8280 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8281 word-wrap under bidirectional display. (Bug#9224)
8283 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8284 is non-zero, even if the data buffer is NULL. Fixes a crash in
8285 vertical-motion with longlines-mode. (Bug#9254)
8287 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8289 * bidi.c <bidi_cache_total_alloc>: Now static.
8290 (bidi_initialize): Initialize bidi_cache_total_alloc.
8292 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8293 cache. (Bug#9221)
8295 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8296 amount allocated this far in `bidi_cache_total_alloc'.
8297 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8298 non-zero, only free the data buffer without restoring the cache
8299 contents. All callers changed.
8301 * dispextern.h (bidi_unshelve_cache): Update prototype.
8303 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8304 (move_it_in_display_line, move_it_to)
8305 (move_it_vertically_backward, move_it_by_lines): Replace the call
8306 to xfree to an equivalent call to bidi_unshelve_cache.
8307 (move_it_in_display_line_to): Fix logic of returning
8308 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8310 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8312 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8313 came from a string character with a `cursor' property. (Bug#9229)
8315 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8317 * Makefile.in (LIB_PTHREAD): New variable.

8361 non-zero.
8363 * bidi.c (bidi_fetch_char): Accept an additional argument
8364 DISP_PROP_P, and pass it to compute_display_string_pos.
8365 Only handle text covered by a display string if DISP_PROP_P is returned
8366 non-zero. All callers of bidi_fetch_char changed.

8389 returned by forward_to_next_line_start to restore the state of
8390 it->bidi_it after backing up to previous newline. (Bug#9212)

8453 Without this fix, if a signal arrives just after memory fills up,
8454 'malloc' might be invoked reentrantly.
8456 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8457 In other words, assume that every image size is allowed, on non-X
8458 hosts. This assumption is probably wrong, but it lets Emacs compile.
8460 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>

8482 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8483 (bidi_find_other_level_edge):
8484 Use ptrdiff_t instead of EMACS_INT where either will do.
8485 This works better on 32-bit hosts configured --with-wide-int.
8486 (bidi_cache_ensure_space): Check for size-calculation overflow.
8487 Use % rather than repeated addition, for better worst-case speed.
8488 Don't set bidi_cache_size until after xrealloc returns, because it
8489 might not return.
8490 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8491 (bidi_cache_ensure_space): Also check that the bidi cache size
8492 does not exceed that of the largest Lisp string or buffer. See Eli
8493 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8495 * alloc.c (__malloc_size_t): Remove.
8496 All uses replaced by size_t. See Andreas Schwab's note
8497 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8499 * image.c: Improve checking for integer overflow.
8500 (check_image_size): Assume that f is nonnull, since
8501 it is always nonnull in practice. This is one less thing to
8502 worry about when checking for integer overflow later.
8503 (x_check_image_size): New function, which checks for integer
8504 overflow issues inside X.
8505 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8506 This removes the need for a memory_full check.
8507 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8508 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8509 (xbm_read_bitmap_data): Change locals back to 'int', since
8510 their values must fit in 'int'.
8511 (xpm_load_image, png_load, tiff_load):
8512 Invoke x_create_x_image_and_pixmap earlier,
8513 to avoid much needless work if the image is too large.
8514 (tiff_load): Treat overly large images as if
8515 x_create_x_image_and_pixmap failed, not as malloc failures.
8516 (gs_load): Use x_check_image_size.
8518 * gtkutil.c: Omit integer casts.
8519 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8520 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8522 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8524 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8525 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8526 would wrongly return t on a 64-bit host.
8528 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8529 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8530 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8531 and therefore cause GCC to emit a bogus diagnostic in some cases.
8533 * image.c: Integer signedness and overflow and related fixes.
8534 This is not an exhaustive set of fixes, but it's time to
8535 record what I've got.
8536 (lookup_pixel_color, check_image_size): Remove redundant decls.
8537 (check_image_size): Don't assume that arbitrary EMACS_INT values
8538 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8539 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8540 (tiff_load, imagemagick_load_image):
8541 Check for overflow in size calculations.
8542 (x_create_x_image_and_pixmap): Remove unnecessary test for
8543 xmalloc returning NULL; that can't happen.
8544 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8545 (xpm_color_bucket): Use better integer hashing function.
8546 (xpm_cache_color): Don't possibly over-allocate memory.
8547 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8548 (gif_memory_source):
8549 Use ptrdiff_t, not int or size_t, to record sizes.
8550 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8551 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8552 either works, as we prefer signed integers.
8553 (tiff_read_from_memory, tiff_write_from_memory):
8554 Return tsize_t, not size_t, since that's what the TIFF API wants.
8555 (tiff_read_from_memory): Don't fail simply because the read would
8556 go past EOF; instead, return a short read.
8557 (tiff_load): Omit no-longer-needed casts.
8558 (Fimagemagick_types): Don't assume size fits into 'int'.
8560 Improve hashing quality when configured --with-wide-int.
8561 * fns.c (hash_string): New function, taken from sxhash_string.
8562 Do not discard information about ASCII character case; this
8563 discarding is no longer needed.
8564 (sxhash-string): Use it. Change sig to match it. Caller changed.
8565 * lisp.h: Declare it.
8566 * lread.c (hash_string): Remove, since we now use fns.c's version.
8567 The fns.c version returns a wider integer if --with-wide-int is
8568 specified, so this should help the quality of the hashing a bit.
8570 * emacs.c: Integer overflow minor fix.
8571 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8572 Define only if GNU_LINUX.
8573 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8575 * dispnew.c: Integer signedness and overflow fixes.
8576 Remove unnecessary forward decls, that were a maintenance hassle.
8577 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8578 All uses changed.
8579 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8580 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8581 (prepare_desired_row, line_draw_cost):
8582 Use int, not unsigned, where either works.
8583 (save_current_matrix, restore_current_matrix):
8584 Use ptrdiff_t, not size_t, where either works.
8585 (init_display): Check for overflow more accurately, and without
8586 relying on undefined behavior.
8588 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8589 Remove, replacing with the new symbols in lisp.h. All uses changed.
8590 * fileio.c (make_temp_name):
8591 * filelock.c (lock_file_1, lock_file):
8592 * xdisp.c (message_dolog):
8593 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8594 Use pMd etc. instead.
8595 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8596 replacing the pWIDE etc. symbols removed from editfns.c.
8598 * keyboard.h (num_input_events): Now uintmax_t.
8599 This is (very slightly) less likely to mess up due to wraparound.
8600 All uses changed.
8602 * buffer.c: Integer signedness fixes.
8603 (alloc_buffer_text, enlarge_buffer_text):
8604 Use ptrdiff_t rather than size_t when either will do, as we prefer
8605 signed integers.
8607 * alloc.c: Integer signedness and overflow fixes.
8608 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8609 (__malloc_size_t): Default to size_t, not to int.
8610 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8611 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8612 Prefer ptrdiff_t to size_t when either would do, as we prefer
8613 signed integers.
8614 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8615 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8616 Now const. Initialize with values that are in range even if char
8617 is signed.
8618 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8619 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8620 These functions do the right thing with sizes > 2**32.
8621 (check_depth): Now ptrdiff_t, not int.
8622 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8623 Adjust to new way of storing sizes. Check for size overflow bugs
8624 in rest of code.
8625 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8626 slightly wrong anyway, as it missed one instance of
8627 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8628 (refill_memory_reserve): Omit needless cast to size_t.
8629 (mark_object_loop_halt): Mark as externally visible.
8631 * xselect.c: Integer signedness and overflow fixes.
8632 (Fx_register_dnd_atom, x_handle_dnd_message):
8633 Use ptrdiff_t, not size_t, since we prefer signed.
8634 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8635 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8636 x_dnd_atoms_size and x_dnd_atoms_length.
8638 * doprnt.c: Prefer signed to unsigned when either works.
8639 * eval.c (verror):
8640 * doprnt.c (doprnt):
8641 * lisp.h (doprnt):
8642 * xdisp.c (vmessage):
8643 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8644 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8645 prefer signed arithmetic to avoid comparison confusion.
8646 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8647 but is a bit tricky.
8649 Assume freestanding C89 headers, string.h, stdlib.h.
8650 * data.c, doprnt.c, floatfns.c, print.c:
8651 Include float.h unconditionally.
8652 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8653 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8654 * regex.c: Likewise for stddef.h, string.h.
8655 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8656 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8657 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8658 (STDC_HEADERS): Remove obsolete defines.
8659 * sysdep.c: Include limits.h unconditionally.
8661 Assume support for memcmp, memcpy, memmove, memset.
8662 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8663 * regex.c (memcmp, memcpy):
8664 Remove; we assume C89 now.
8666 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8667 (__malloc_safe_bcopy): Remove; no longer needed.
8669 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8670 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8671 well either way, and we prefer signed to unsigned.
8673 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8675 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8676 closes the connection while we're reading (bug#9182).
8678 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8680 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8681 are specified (Bug#9168).
8683 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8685 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8686 Found by GCC static checking and --with-wide-int on a 32-bit host.
8688 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8690 * xdisp.c (compute_display_string_pos): Fix logic of caching
8691 previous display string position. Initialize cached_prev_pos to
8692 -1. Fixes slow-down at the beginning of a buffer.
8694 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8696 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8697 for attrs[LFACE_FONTSET_INDEX].
8699 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8701 * xml.c (parse_region): Remove unused local
8702 that was recently introduced.
8704 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8706 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8707 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8709 * xdisp.c (move_it_in_display_line_to): Record the best matching
8710 position for TO_CHARPOS while scanning the line, and restore it on
8711 exit if none of the characters scanned was an exact match.
8712 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8713 when exact match is impossible due to invisible text, and the
8714 lines are truncated.
8716 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8718 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8719 for OSX >= 10.7.
8721 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8723 Fix a significant slow-down of cursor motion with C-n, C-p,
8724 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8725 auto-repeat under bidi redisplay in fontified buffers.
8726 * xdisp.c (compute_stop_pos_backwards): New function.
8727 (next_element_from_buffer): Call compute_stop_pos_backwards to
8728 find a suitable prev_stop when we find ourselves before
8729 base_level_stop.
8730 (reseat): Don't look for prev_stop, as that could mean a very long
8731 run.
8732 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8733 <cached_disp_overlay_modiff>: Cache for last found display string
8734 position.
8735 (compute_display_string_pos): Return the cached position if asked
8736 about the same buffer in the same area of character positions, and
8737 the buffer wasn't changed since the time the display string
8738 position was cached.
8740 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8742 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8743 is an integer, which is important for empty lines. (Bug#9149)
8745 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8747 * frame.c (Fmodify_frame_parameters): In tty case, update the
8748 default face if necessary (Bug#4238).
8750 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8752 * editfns.c (Fstring_to_char): No need to explain what a character
8753 is in the docstring (Bug#6576).
8755 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8757 * xml.c (parse_region): Make sure we always return a tree.
8759 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8761 * xml.c (parse_region): If a document contains only comments,
8762 return that, too.
8764 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8766 * xml.c (make_dom): Return comments, too.
8768 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8770 Port to OpenBSD.
8771 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8772 and the surrounding thread.
8773 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8774 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8775 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8776 timer goes off.
8777 * s/openbsd.h (BROKEN_SIGIO): Define.
8778 * unexelf.c (unexec) [__OpenBSD__]:
8779 Don't update the .mdebug section of the Alpha COFF symbol table.
8781 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8783 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8784 (bug#8460).
8786 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8788 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8789 This fixes some race conditions on the permissions of any newly
8790 created file.
8792 * alloc.c (valid_pointer_p): Use pipe, not open.
8793 This fixes some permissions issues when debugging.
8795 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8796 If fchown fails to set both uid and gid, try to set just gid,
8797 as that is sometimes allowed. Adjust the file's mode to eliminate
8798 setuid or setgid bits that are inappropriate if fchown fails.
8800 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8802 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8803 to compare Lisp_Objects.
8804 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8805 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8806 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8808 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8810 * lread.c (read_integer): Unread even EOF character.
8811 (read1): Likewise. Properly record start position of symbol.
8813 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8814 symbol character follows.
8816 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8818 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8819 This works around a problem with the previous change to Fcopy_file.
8820 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8821 and without this change, GCC might complain about discarding
8822 fchown's return value.
8824 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8826 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8828 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8830 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8832 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8834 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8835 it's used from the C level.
8837 * process.c: Use the same condition for POLL_FOR_INPUT in both
8838 keyboard.c and process.c (bug#1858).
8840 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8842 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8843 (Fgnutls_boot): Use it.
8845 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8847 * doc.c (Fsubstitute_command_keys): Revert last change.
8849 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8851 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8852 quotes the next character, and doesn't affect other longer
8853 sequences (bug#8935).
8855 * lread.c (syms_of_lread): Clarify that is isn't only
8856 `eval-buffer' and `eval-defun' that's affected by
8857 `lexical-binding' (bug#8460).
8859 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8861 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8862 bidi redisplay when a line includes both an image and is truncated.
8864 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8866 Fix minor problems found by static checking.
8867 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8868 (elsz): Now a signed constant, not a size_t var. We prefer signed
8869 types to unsigned, to avoid integer comparison confusion. Without
8870 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8871 "cannot optimize loop, the loop counter may overflow", a symptom
8872 of the confusion.
8873 * indent.c (Fvertical_motion): Mark locals as initialized.
8874 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8876 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8878 * search.c (Fre_search_backward): Mention `case-fold-search' in
8879 all the re_search_* functions (bug#8138).
8881 * keyboard.c (Fopen_dribble_file): Document when the file is
8882 closed (bug#8056).
8884 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8886 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8887 bidi_cache_idx.
8889 Support bidi reordering of display and overlay strings.
8890 * xdisp.c (compute_display_string_pos)
8891 (compute_display_string_end): Accept additional argument STRING.
8892 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8893 (reseat_to_string): Initialize bidi_it->string.s and
8894 bidi_it->string.schars.
8895 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8896 NULL (avoids a crash in bidi_paragraph_init).
8897 Initialize itb.string.lstring.
8898 (init_iterator): Call bidi_init_it only of a valid
8899 buffer position was specified. Initialize paragraph_embedding to
8900 L2R.
8901 (reseat_to_string): Initialize the bidi iterator.
8902 (display_string): If we need to ignore text properties of
8903 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8904 original value of -1 will not work with bidi.)
8905 (compute_display_string_pos): First arg is now struct
8906 `text_pos *'; all callers changed. Support display properties on
8907 Lisp strings.
8908 (compute_display_string_end): Support display properties on Lisp
8909 strings.
8910 (init_iterator, reseat_1, reseat_to_string): Initialize the
8911 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8912 when iterating on a string not from display properties).
8913 (compute_display_string_pos, compute_display_string_end):
8914 Fix calculation of the object to scan. Fixes an error when using
8915 arrow keys.
8916 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8917 base_level_stop; instead, set base_level_stop to BEGV.
8918 Fixes crashes in vertical-motion.
8919 (next_element_from_buffer): Improve commentary for when
8920 the iterator is before prev_stop.
8921 (init_iterator): Initialize bidi_p from the default value of
8922 bidi-display-reordering, not from buffer-local value. Use the
8923 buffer-local value only if initializing for buffer iteration.
8924 (handle_invisible_prop): Support invisible properties on strings
8925 that are being bidi-reordered.

9398 (clone_per_buffer_values): Don't assume that

9400 This isn't true in general, and it's particularly not true
9401 if Emacs is configured with --with-wide-int.
9402 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

9437 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
9439 Random fixes. E.g., (random) never returned negative values.
9440 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9441 subseconds part to the entropy, as that's a bit more random.
9442 Prefer signed to unsigned, since the signedness doesn't matter and
9443 in general we prefer signed. When given a limit, use a
9444 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9445 latter isn't right if USE_2_TAGS_FOR_INTS.
9446 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9447 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9449 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9451 * textprop.c (text_property_stickiness):

9460 This is more efficient than Ffile_directory_p and avoids a minor race.
9462 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9464 * buffer.c (Foverlay_put): Say what the return value is
9465 (bug#7835).
9467 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9468 is a directory before asking whether to use the file name
9469 (bug#7564).
9470 (barf_or_query_if_file_exists): Make the "File is a directory"
9471 error be more correct.
9473 * fns.c (Frequire): Remove the mention of the .gz files, since
9474 that's installation-specific, but keep the mention of
9475 `get-load-suffixes'.
9477 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9479 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9487 Qgnutls_bootprop_verify_error (which is no longer used).
9489 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
9490 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9491 Also (re)move comments that are misplaced or no longer relevant.
9493 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9495 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9554 (syms_of_keymap): Defsubr make-composed-keymap.
9555 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

9590 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9592 * eval.c (struct backtrace): Simplify and port the data structure.
9593 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9594 signed bit field, as this assumption is not portable and it makes
9595 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9596 "char debug_on_exit : 1" as this is not portable either; instead,
9597 use the portable "unsigned int debug_on_exit : 1". Remove unused
9598 member evalargs. Remove obsolete comments about cc bombing out.
9600 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9815 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9816 The following patches are for when GLYPH_DEBUG && !XASSERT.
9817 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9818 * dispnew.c (flush_stdout):
9819 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9820 Mark as externally visible.
9821 * dispnew.c (check_window_matrix_pointers): Now static.
9822 * dispnew.c (window_to_frame_vpos):
9823 * xfns.c (unwind_create_frame):
9824 * xterm.c (x_check_font): Remove unused local.
9825 * scroll.c (CHECK_BOUNDS):
9826 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9827 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9828 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9829 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9830 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9831 Now static.
9832 (debug_method_add): Use va_list and vsprintf rather than relying
9833 on undefined behavior with wrong number of arguments.
9834 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9835 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9836 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9837 since we're not interested in debugging glyphs with old libraries.
9838 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9839 GCC 4.6.0's static checking.
9841 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

9852 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9853 (x_create_bitmap_from_xpm_data):
9854 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9855 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9856 (.bitmaps_last):
9857 * xfaces.c (load_pixmap):
9858 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9859 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9860 (.bitmaps_last, struct x_output.icon_bitmap):
9861 Use ptrdiff_t, not int, for bitmap indexes.
9862 (x_allocate_bitmap_record): Check for size overflow.
9863 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9865 Use ptrdiff_t, not int, for overlay counts.
9866 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9867 * editfns.c (overlays_around, get_pos_property):
9868 * textprop.c (get_char_property_and_overlay):
9869 * xdisp.c (next_overlay_change, note_mouse_highlight):
9870 * xfaces.c (face_at_buffer_position):
9871 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9872 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9873 (Fnext_overlay_change, Fprevious_overlay_change)
9874 (mouse_face_overlay_overlaps, Foverlays_in):
9875 Use ptrdiff_t, not int, for sizes.
9876 (overlays_at, overlays_in): Check for size-calculation overflow.
9878 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9880 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9881 (x_session_initialize): Do not assume string length fits in int.
9883 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9884 This is unlikely, but can occur if DPI is outlandish.
9886 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9887 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9889 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9890 * xrdb.c (magic_file_p, search_magic_path):
9891 Omit last arg SUFFIX; it was always 0. All callers changed.
9892 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9894 * xfont.c (xfont_match): Avoid need for strlen.
9896 * xfns.c: Don't assume strlen fits in int.
9897 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9899 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9900 not unsigned long, as we prefer signed integers. All callers changed.
9901 Detect integer overflow in repeat count.
9902 (message_dolog): Don't assume print length fits in 39 bytes.
9903 (display_mode_element): Don't assume strlen fits in int.
9905 * termcap.c: Don't assume sizes fit in int and never overflow.
9906 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9907 (gobble_line): Check for size-calculation overflow.
9909 * minibuf.c (Fread_buffer):
9910 * lread.c (intern, intern_c_string):
9911 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9912 Don't assume string length fits in int.
9914 * keyboard.c (parse_tool_bar_item):
9915 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9917 * font.c: Don't assume string length fits in int.
9918 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9919 Use ptrdiff_t, not int.
9920 (font_intern_prop): Don't assume string length fits in int.
9921 Don't assume integer property fits in fixnum.
9922 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9924 * filelock.c: Fix some buffer overrun and integer overflow issues.
9925 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9926 Reformulate so as not to need the command string.
9927 Invoke gzip -cd rather than gunzip, as it's more portable.
9928 (lock_info_type, lock_file_1, lock_file):
9929 Don't assume pid_t and time_t fit in unsigned long.
9930 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9931 (current_lock_owner): Prefer signed type for sizes.
9932 Use memcpy, not strncpy, where memcpy is what is really wanted.
9933 Don't assume (via atoi) that time_t and pid_t fit in int.
9934 Check for time_t and/or pid_t out of range, e.g., via a network share.
9935 Don't alloca where an auto var works fine.
9937 * fileio.c: Fix some integer overflow issues.
9938 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9939 Don't assume string length fits in int.
9940 (directory_file_name): Don't assume string length fits in long.
9941 (make_temp_name): Don't assume pid fits in int, or that its print
9942 length is less than 20.
9944 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9946 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9948 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9950 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9951 We prefer signed integers, even for size calculations.
9953 * emacs.c: Don't assume string length fits in 'int'.
9954 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9955 (main): Don't invoke strlen when not needed.
9957 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

9960 * callproc.c (getenv_internal_1, getenv_internal)
9961 (Fgetenv_internal):
9962 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9964 * lread.c (invalid_syntax): Omit length argument.
9965 All uses changed. This doesn't fix a bug, but it simplifies the
9966 code away from its former Hollerith-constant appearance, and it's
9967 one less 'int' to worry about when looking at integer-overflow issues.
9968 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9970 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9971 This didn't break anything, but it didn't help either.
9972 It's confusing to put a bogus integer in a place where the actual
9973 value does not matter.
9974 (LIST_END_P): Remove unused macro and its bogus comment.
9975 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9977 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9978 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9979 implementation.
9980 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9981 We prefer signed types, and the value cannot exceed the EMACS_INT
9982 range anyway (because otherwise the length would not be representable).
9983 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9984 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9985 This avoids a GCC warning when WIDE_EMACS_INT.
9987 * indent.c (sane_tab_width): New function.
9988 (current_column, scan_for_column, Findent_to, position_indentation)
9989 (compute_motion): Use it. This is just for clarity.
9990 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9992 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9994 * lisp.h (lint_assume): New macro.
9995 * composite.c (composition_gstring_put_cache):
9996 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9998 * editfns.c, insdel.c:
9999 Omit unnecessary forward decls, to simplify future changes.
10001 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10003 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10005 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10006 Use much-faster test for byte-length change.
10007 Don't assume string byte-length fits in 'int'.
10008 Check that character arg fits in 'int'.
10009 (mapcar1): Declare byte as byte, for clarity.
10011 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10013 * fns.c (concat): Catch string overflow earlier.
10014 Do not rely on integer wraparound.
10016 * dispextern.h (struct it.overlay_strings_charpos)
10017 (struct it.selective): Now EMACS_INT, not int.
10018 * xdisp.c (forward_to_next_line_start)
10019 (back_to_previous_visible_line_start)
10020 (reseat_at_next_visible_line_start, next_element_from_buffer):
10021 Don't arbitrarily truncate the value of 'selective' to int.
10023 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10025 * composite.c: Don't truncate sizes to 'int'.
10026 (composition_gstring_p, composition_reseat_it)
10027 (composition_adjust_point): Use EMACS_INT, not int.
10028 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10029 not EMACS_UINT, for indexes.
10031 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10033 * buffer.c: Include <verify.h>.
10034 (struct sortvec.priority, struct sortstr.priority):
10035 Now EMACS_INT, not int.
10036 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10037 (struct sortstr.size, record_overlay_string)
10038 (struct sortstrlist.size, struct sortlist.used):
10039 Don't truncate size to int.
10040 (record_overlay_string): Check for size-calculation overflow.
10041 (init_buffer_once): Check at compile-time, not run-time.
10043 2011-06-22 Jim Meyering <meyering@redhat.com>
10045 Don't leak an XBM-image-sized buffer
10046 * image.c (xbm_load): Free the image buffer after using it.
10048 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10050 Port to Sun C.
10051 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10052 that Sun C diagnosed.
10053 * fns.c (secure_hash): Fix pointer signedness issue.
10054 * intervals.c (static_offset_intervals): New function.
10055 (offset_intervals): Use it.
10057 2011-06-21 Leo Liu <sdl.web@gmail.com>
10059 * deps.mk (fns.o):
10060 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10061 sha512.h.
10063 * fns.c (secure_hash): Rename from crypto_hash_function and change
10064 the first arg to accept symbols.
10065 (Fsecure_hash): New primitive.
10066 (syms_of_fns): New symbols.
10068 2011-06-20 Deniz Dogan <deniz@dogan.se>
10070 * process.c (Fset_process_buffer): Clarify return value in
10071 docstring.
10073 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10075 * dispnew.c (add_window_display_history): Use BVAR.
10077 * xdisp.c (debug_method_add): Use BVAR.
10078 (check_window_end, dump_glyph_matrix, dump_glyph)
10079 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10081 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10082 Likewise.
10084 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10085 check till after the cache is created in init_frame_faces.
10087 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10089 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10091 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10093 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10094 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10095 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10097 Improve buffer-overflow checking (Bug#8873).
10098 * fileio.c (Finsert_file_contents):
10099 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10100 Remove the old (too-loose) buffer overflow checks.
10101 They weren't needed, since make_gap checks for buffer overflow.
10102 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10103 The old code merely checked for Emacs fixnum overflow, and relied
10104 on undefined (wraparound) behavior. The new code avoids undefined
10105 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10107 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10108 Tune. Don't use wider integers than needed. Don't use alloca.
10109 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10111 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10113 * insdel.c, lisp.h (buffer_overflow): New function.
10114 (insert_from_buffer_1, replace_range, replace_range_2):
10115 * insdel.c (make_gap_larger):
10116 * editfns.c (Finsert_char):
10117 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10119 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10121 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10123 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10125 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10126 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10128 * fileio.c: Don't assume EMACS_INT fits in off_t.
10129 (emacs_lseek): New static function.
10130 (Finsert_file_contents, Fwrite_region): Use it.
10131 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10133 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10135 * fns.c: Don't overflow int when computing a list length.
10136 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10137 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10138 truncation on 64-bit hosts. Check for QUIT every
10139 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10140 faster and is responsive enough.
10141 (Flength): Report an error instead of overflowing an integer.
10142 (Fsafe_length): Return a float if the value is not representable
10143 as a fixnum. This shouldn't happen except in contrived situations.
10144 (Fnthcdr, Fsort): Don't assume list length fits in int.
10145 (Fcopy_sequence): Don't assume vector length fits in int.
10147 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10148 (header_size, word_size): New constants.
10149 (allocate_vectorlike): Don't check size overflow here.
10150 (allocate_vector): Check it here instead, since this is the only
10151 caller of allocate_vectorlike that could cause overflow.
10152 Check that the new vector's length is representable as a fixnum.
10154 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10155 The previous code was bogus. For example, next_almost_prime (32)
10156 returned 39, which is undesirable as it is a multiple of 3; and
10157 next_almost_prime (24) returned 25, which is a multiple of 5 so
10158 why was the code bothering to check for multiples of 7?
10160 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10162 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10164 Variadic C functions now count arguments with ptrdiff_t.
10165 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10166 Back then I didn't know that the Emacs coding style prefers signed int.
10167 Also, in the meantime I found a few more instances where arguments
10168 were being counted with int, which may truncate counts on 64-bit
10169 machines, or EMACS_INT, which may be unnecessarily wide.
10170 * lisp.h (struct Lisp_Subr.function.aMANY)
10171 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10172 Arg counts are now ptrdiff_t, not size_t.
10173 All variadic functions and their callers changed accordingly.
10174 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10175 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10176 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10177 * callint.c (Fcall_interactively): Check arg count for overflow,
10178 to avoid potential buffer overrun. Use signed char, not 'int',
10179 for 'varies' array, so that we needn't bother to check its size
10180 calculation for overflow.
10181 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10182 * eval.c (apply_lambda):
10183 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10184 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10185 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10187 * callint.c (Fcall_interactively): Don't use index var as event count.
10189 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10190 * mem-limits.h (SIZE): Remove; no longer used.
10192 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10194 Remove unnecessary casts.
10195 * xterm.c (x_term_init):
10196 * xfns.c (x_set_border_pixel):
10197 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10198 These aren't needed now that we assume ANSI C.
10200 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10201 It's more likely to cause problems (due to unsigned overflow)
10202 than to cure them.
10204 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10206 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10208 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10210 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10212 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10214 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10216 GLYPH_CODE_FACE returns EMACS_INT, not int.
10217 * dispextern.h (merge_faces):
10218 * xfaces.c (merge_faces):
10219 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10220 Don't assume EMACS_INT fits in int.
10222 * character.h (CHAR_VALID_P): Remove unused parameter.
10223 * fontset.c, lisp.h, xdisp.c: All uses changed.
10225 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10227 * fns.c (concat): Minor tuning based on overflow analysis.
10228 This doesn't fix any bugs. Use int to hold character, instead
10229 of constantly refetching from Emacs object. Use XFASTINT, not
10230 XINT, for value known to be a character. Don't bother comparing
10231 a single byte to 0400, as it's always less.
10233 * floatfns.c (Fexpt):
10234 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10236 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10237 for characters.
10239 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10241 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10242 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10243 incorrectly succeed when S was a string, because 4294967386 was
10244 truncated before it was used.
10246 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10247 Otherwise, an out-of-range integer could cause undefined behavior
10248 on a 64-bit host.
10250 * composite.c: Use int, not EMACS_INT, for characters.
10251 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10252 EMACS_INT, for values that are known to be in character range.
10253 This doesn't fix any bugs but is the usual style inside Emacs and
10254 may generate better code on 32-bit machines.
10256 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10257 This is for reasons similar to the recent CHAR_STRING fix.
10258 * charset.c (Fencode_char): Check that character arg is actually
10259 a character. Pass an int to ENCODE_CHAR.
10260 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10261 wider than 'int', as a compile-time check to prevent future regressions
10262 in this area.
10264 * character.c (char_string): Remove unnecessary casts.
10266 Make sure a 64-bit char is never passed to CHAR_STRING.
10267 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10268 by silently ignoring the top 32 bits, allowing some values
10269 that were far too large to be valid characters.
10270 * character.h: Include <verify.h>.
10271 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10272 arguments are no wider than unsigned, as a compile-time check
10273 to prevent future regressions in this area.
10274 * data.c (Faset):
10275 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10276 (Fsubst_char_in_region):
10277 * fns.c (concat):
10278 * xdisp.c (decode_mode_spec_coding):
10279 Adjust to CHAR_STRING's new requirement.
10280 * editfns.c (Finsert_char, Fsubst_char_in_region):
10281 * fns.c (concat): Check that character args are actually
10282 characters. Without this test, these functions did the wrong
10283 thing with wildly out-of-range values on 64-bit hosts.
10285 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10286 These casts should not be needed on 32-bit hosts, either.
10287 * keyboard.c (read_char):
10288 * lread.c (Fload): Remove casts to unsigned.
10290 * lisp.h (UNSIGNED_CMP): New macro.
10291 This fixes comparison bugs on 64-bit hosts.
10292 (ASCII_CHAR_P): Use it.
10293 * casefiddle.c (casify_object):
10294 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10295 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10296 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10297 * dispextern.h (FACE_FROM_ID):
10298 * keyboard.c (read_char): Use UNSIGNED_CMP.
10300 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10301 not to EMACS_INT, to avoid GCC warning.
10303 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10305 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10306 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10307 isn't needed on 32-bit machines.
10309 * buffer.c (Fgenerate_new_buffer_name):
10310 Use EMACS_INT for count, not int.
10311 (advance_to_char_boundary): Return EMACS_INT, not int.
10313 * data.c (Qcompiled_function): Now static.
10315 * window.c (window_body_lines): Now static.
10317 * image.c (gif_load): Rename local to avoid shadowing.
10319 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10320 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10321 * alloc.c (make_save_value): Integer argument is now of type
10322 ptrdiff_t, not int.
10323 (mark_object): Use ptrdiff_t, not int.
10324 * lisp.h (pD): New macro.
10325 * print.c (print_object): Use it.
10327 * alloc.c: Use EMACS_INT, not int, to count objects.
10328 (total_conses, total_markers, total_symbols, total_vector_size)
10329 (total_free_conses, total_free_markers, total_free_symbols)
10330 (total_free_floats, total_floats, total_free_intervals)
10331 (total_intervals, total_strings, total_free_strings):
10332 Now EMACS_INT, not int. All uses changed.
10333 (Fgarbage_collect): Compute overall total using a double, so that
10334 integer overflow is less likely to be a problem. Check for overflow
10335 when converting back to an integer.
10336 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10337 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10338 These were 'int' variables that could overflow on 64-bit hosts;
10339 they were never used, so remove them instead of repairing them.
10340 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10341 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10342 Previously, this ceilinged at INT_MAX, but that doesn't work on
10343 64-bit machines.
10344 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10346 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10347 (allocate_vectorlike): Check for ptrdiff_t overflow.
10348 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10349 when a (possibly-narrower) signed value would do just as well.
10350 We prefer using signed arithmetic, to avoid comparison confusion.
10352 * alloc.c: Catch some string size overflows that we were missing.
10353 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10354 for convenience in STRING_BYTES_MAX.
10355 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10356 The definition here is exact; the one in lisp.h was approximate.
10357 (allocate_string_data): Check for string overflow. This catches
10358 some instances we weren't catching before. Also, it catches
10359 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10360 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10361 and ptrdiff_t and EMACS_INT are both 64 bits.
10363 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10364 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10365 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10367 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10369 * alloc.c (Fmake_string): Check for out-of-range init.
10371 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10373 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10375 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10377 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10378 xg_get_default_scrollbar_width.
10380 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10381 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10382 (style_changed_cb): Call update_theme_scrollbar_width and call
10383 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10384 all frames (Bug#8505).

10391 (xg_get_default_scrollbar_width): Move code to
10392 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

10395 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10397 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10399 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10401 * frame.c (make_frame): Call other_buffer_safely instead of
10402 other_buffer.
10404 * window.c (temp_output_buffer_show): Call display_buffer with
10405 second argument Vtemp_buffer_show_specifiers and reset latter
10406 immediately after the call.
10407 (Vtemp_buffer_show_specifiers): New variable.
10408 (auto_window_vscroll_p, next_screen_context_lines)
10409 (Vscroll_preserve_screen_position): Remove leading asterisks from
10410 doc-strings.

10942 instead of using explicit *_CHAR codes.
10943 (bidi_resolve_explicit, bidi_resolve_weak):

10956 * xdisp.c (set_cursor_from_row): Set start and stop points
10957 according to the row's direction when priming the loop that looks

10960 (display_prop_intangible_p): Reimplement to call
10961 handle_display_spec instead of single_display_spec_intangible_p.
10962 Accept 3 additional arguments needed by handle_display_spec.
10963 This fixes incorrect cursor motion across display property with complex

10973 value of a `display' property is a "replacing spec".
10974 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10975 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11003 All callers changed. (Bug#8762)
11005 * gnutls.c: Use Emacs's memory allocators.
11006 Without this change, the gnutls library would invoke malloc etc.
11007 directly, which causes problems on non-SYNC_INPUT hosts, and which
11008 runs afoul of improving memory_full behavior. (Bug#8761)
11009 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11010 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11011 xfree instead of the default malloc, realloc, free.
11012 (Fgnutls_boot): No need to check for memory allocation failure,
11013 since xmalloc does that for us.

11042 need to be updated by these changes.
11043 * fns.c (make_hash_table, maybe_resize_hash_table):
11044 Check for integer overflow with large hash tables.
11045 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11046 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11047 (SXHASH_REDUCE): New macro.
11048 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11049 Use it instead of discarding useful hash info with large hash values.
11050 (sxhash_float): New function.
11051 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11052 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11053 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11054 Rewrite to use FIXNUM_BITS, as this simplifies things.
11055 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11056 Adjust signatures to match updated version of code.
11057 (consing_since_gc): Now EMACS_INT, since a single hash table can
11058 use more than INT_MAX bytes.

11092 pointer. Remove declaration, not needed.
11094 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11096 Use 'inline', not 'INLINE'.
11097 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11098 * alloc.c, fontset.c (INLINE): Remove.
11099 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11100 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11101 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11102 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11103 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11105 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11107 Make it possible to run ./temacs.
11109 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11110 syms_of_callproc does the same thing. Remove test for
11111 "initialized", do it in the caller.
11112 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11114 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11116 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11117 (read_minibuf): Use get_minibuffer.
11118 (syms_of_minibuf): Use DEFSYM.
11119 (Qmetadata): New var.
11120 * data.c (Qbuffer): Don't make it static.
11121 (syms_of_data): Use DEFSYM.
11123 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11125 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11126 (CCL_CODE_MIN): New macro.
11128 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11130 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11132 * eval.c (Qdebug): Now static.
11133 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11134 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11135 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11137 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11139 * image.c: Various fixes to ImageMagick code comments.
11140 (Fimagemagick_types): Doc fix.
11142 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11144 Minor fixes prompted by GCC 4.6.0 warnings.
11146 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11148 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11149 (x_clipboard_manager_save_all): Move extern decl to ...
11150 * xterm.h: ... here, so that it can be checked for consistency.
11152 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11154 * xselect.c (x_clipboard_manager_save_frame)
11155 (x_clipboard_manager_save_all): New functions.
11156 (Fx_clipboard_manager_save): Lisp function deleted.
11158 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11159 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11161 * xterm.h: Update prototype.
11163 2011-05-28 William Xu <william.xwl@gmail.com>
11165 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11166 exiting (Bug#8239).
11168 2011-05-28 Jim Meyering <meyering@redhat.com>
11170 Avoid a sign-extension bug in crypto_hash_function.
11171 * fns.c (to_uchar): Define.
11172 (crypto_hash_function): Use it to convert some newly-signed
11173 variables to unsigned, to avoid sign-extension bugs. For example,
11174 without this change, (md5 "truc") would evaluate to
11175 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11176 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11177 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11179 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11181 Integer overflow fixes.
11183 * dbusbind.c: Serial number integer overflow fixes.
11184 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11185 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11186 to hold a serial number that is too large for a fixnum.
11187 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11188 Check for serial numbers out of range. Decode any serial number
11189 that was so large that it became a float. (Bug#8722)
11191 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11192 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11193 Use XFASTINT rather than XUINT when numbers are nonnegative.
11194 (xd_append_arg, Fdbus_method_return_internal):
11195 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11196 arguments, check that Lisp number is nonnegative, rather than
11197 silently wrapping negative numbers around. (Bug#8722)
11198 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11199 (Bug#8722)
11201 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11203 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11205 ccl: Add integer overflow checks.
11206 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11207 (IN_INT_RANGE): New macros.
11208 (ccl_driver): Use them to check for integer overflow when
11209 decoding a CCL program. Many of the new checks are whether XINT (x)
11210 fits in int; it doesn't always, on 64-bit hosts. The new version
11211 doesn't catch all possible integer overflows, but it's an
11212 improvement. (Bug#8719)
11214 * alloc.c (make_event_array): Use XINT, not XUINT.
11215 There's no need for unsigned here.
11217 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11218 This follows up to the 2011-05-06 change that substituted uintptr_t
11219 for EMACS_INT. This case wasn't caught back then.
11221 Rework Fformat to avoid integer overflow issues.
11222 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11223 now (part of C89). Include <verify.h>.
11224 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11225 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11226 (Fformat): Avoid the prepass trying to compute sizes; it was only
11227 approximate and thus did not catch overflow reliably. Instead, walk
11228 through the format just once, formatting and computing sizes as we go,
11229 checking for integer overflow at every step, and allocating a larger
11230 buffer as needed. Keep track separately whether the format is
11231 multibyte. Keep only the most-recently calculated precision, rather
11232 than them all. Record whether each argument has been converted to
11233 string. Use EMACS_INT, not int, for byte and char and arg counts.
11234 Support field widths and precisions larger than INT_MAX. Avoid
11235 sprintf's undefined behavior with conversion specifications such as %#d
11236 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11237 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11238 formatting out-of-range floating point numbers with int
11239 formats. (Bug#8668)
11241 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11243 * data.c: Avoid integer truncation in expressions involving floats.
11244 * data.c: Include <intprops.h>.
11245 (arith_driver): When there's an integer overflow in an expression
11246 involving floating point, convert the integers to floating point
11247 so that the resulting value does not suffer from catastrophic
11248 integer truncation. For example, on a 64-bit host (* 4
11249 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11250 Do not rely on undefined behavior after integer overflow.
11252 merge count_size_as_multibyte, parse_str_to_multibyte
11253 * character.c, character.h (count_size_as_multibyte):
11254 Rename from parse_str_to_multibyte; all uses changed.
11255 Check for integer overflow.
11256 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11257 since it's now a duplicate of the other. This is more of
11258 a character than a buffer op, so better that it's in character.c.
11259 * fns.c, print.c: Adjust to above changes.
11261 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11263 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11265 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11267 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11268 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11269 (x_clipboard_manager_save): Now static.
11270 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11272 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11273 (crypto_hash_function): Now static.
11274 Fix pointer signedness problems. Avoid unnecessary initializations.
11276 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11278 * termhooks.h (Vselection_alist): Make it terminal-local.
11280 * terminal.c (create_terminal): Initialize it.
11282 * xselect.c: Support for clipboard managers.
11283 (Vselection_alist): Move to termhooks.h as terminal-local var.
11284 (LOCAL_SELECTION): New macro.
11285 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11286 (symbol_to_x_atom): Remove gratuitous arg.
11287 (x_handle_selection_request, lisp_data_to_selection_data)
11288 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11289 (x_own_selection, x_get_local_selection, x_convert_selection):
11290 New arg, specifying work frame. Use terminal-local Vselection_alist.
11291 (some_frame_on_display): Delete unused function.
11292 (Fx_own_selection_internal, Fx_get_selection_internal)
11293 (Fx_disown_selection_internal, Fx_selection_owner_p)
11294 (Fx_selection_exists_p): New optional frame arg.
11295 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11296 (x_handle_selection_clear): Don't treat other terminals with the
11297 same keyboard specially. Use the terminal-local Vselection_alist.
11298 (x_clear_frame_selections): Use Frun_hook_with_args.
11300 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11302 * xterm.h: Add support for those atoms.
11304 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11306 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11307 (converted_selections, conversion_fail_tag): New global variables.
11308 (x_selection_request_lisp_error): Free the above.
11309 (x_get_local_selection): Remove unnecessary code.
11310 (x_reply_selection_request): Args changed; handle arbitrary array
11311 of converted selections stored in converted_selections.
11312 Separate the XChangeProperty and SelectionNotify steps.
11313 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11314 (x_convert_selection): New function.
11315 (x_handle_selection_event): Simplify.
11316 (x_get_foreign_selection): Don't ignore incoming requests while
11317 waiting for an answer; this will fail when we implement
11318 SAVE_TARGETS, and seems unnecessary anyway.
11319 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11320 (Vx_sent_selection_functions): Doc fix.
11322 2011-05-26 Leo Liu <sdl.web@gmail.com>
11324 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11326 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11328 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11330 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11331 for fringe update if it has periodic bitmap.
11332 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11333 and fringe_bitmap_periodic_p.
11335 * fringe.c (get_fringe_bitmap_data): New function.
11336 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11337 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11338 row. Mark glyph row for fringe update if periodicity changed.
11340 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11341 for fringe update unless it has periodic bitmap.
11343 2011-05-25 Kenichi Handa <handa@m17n.org>
11345 * xdisp.c (get_next_display_element): Set correct it->face_id for
11346 a static composition.
11348 2011-05-24 Leo Liu <sdl.web@gmail.com>
11350 * deps.mk (fns.o):
11351 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11353 * fns.c (crypto_hash_function, Fsha1): New function.
11354 (Fmd5): Use crypto_hash_function.
11355 (syms_of_fns): Add Ssha1.
11357 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11359 * gnutls.c: Remove unused macros.
11360 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11361 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11362 Remove macros that are defined and never used.
11363 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11365 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11367 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11368 (Fx_get_selection_internal): Minor cleanup.
11369 (Fx_own_selection_internal): Rename arguments for consistency with
11370 select.el.
11372 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11374 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11376 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11378 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11380 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11382 * dispnew.c (scrolling_window): Don't exclude the case that the
11383 last enabled row in the desired matrix touches the bottom boundary.
11385 2011-05-21 Glenn Morris <rgm@gnu.org>
11387 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11388 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11389 and add some more files.
11391 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11393 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11394 report_file_error introduced by the change from 2011-05-07.
11396 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11398 * systime.h (Time): Define only if emacs is defined.
11399 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11400 where the include path doesn't have X11/X.h by default. See
11401 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11403 2011-05-20 Kenichi Handa <handa@m17n.org>
11405 * composite.c (find_automatic_composition): Fix previous change.
11407 2011-05-20 Glenn Morris <rgm@gnu.org>
11409 * lisp.mk: New file, split from Makefile.in.
11410 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11411 (shortlisp): Remove.
11412 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11414 2011-05-19 Glenn Morris <rgm@gnu.org>
11416 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11417 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11418 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11419 (lisp): Set the order to that of loadup.el.
11420 (shortlisp): Make it a copy of $lisp.
11421 (SOME_MACHINE_LISP): Remove.
11422 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11423 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11425 2011-05-18 Kenichi Handa <handa@m17n.org>
11427 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11428 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11429 (find_automatic_composition): Mostly rewrite for efficiency.
11431 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11433 * makefile.w32-in: Update dependencies.
11435 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11437 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11438 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11440 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11442 Fix some integer overflow issues, such as string length overflow.
11444 * insdel.c (count_size_as_multibyte): Check for string overflow.
11446 * character.c (lisp_string_width): Check for string overflow.
11447 Use EMACS_INT, not int, for string indexes and lengths; in
11448 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11449 the resulting string length overflows an EMACS_INT; instead,
11450 report a string overflow if no precision given. When checking for
11451 precision exhaustion, use a check that cannot possibly have
11452 integer overflow. (Bug#8675)
11453 * character.h (lisp_string_width): Adjust to new signature.
11455 * alloc.c (string_overflow): New function.
11456 (Fmake_string): Use it. This doesn't change behavior, but saves
11457 a few bytes and will simplify future changes.
11458 * character.c (string_escape_byte8): Likewise.
11459 * lisp.h (string_overflow): New decl.
11461 Fixups, following up to the user-interface timestamp change.
11462 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11463 for UI timestamps, instead of unsigned long.
11464 * msdos.c (mouse_get_pos): Likewise.
11465 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11466 * w32gui.h (Time): Define by including "systime.h" rather than by
11467 declaring it ourselves. (Bug#8664)
11469 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11470 * image.c (clear_image_cache): Likewise.
11472 * term.c (term_mouse_position): Don't assume time_t wraparound.
11474 Be more systematic about user-interface timestamps.
11475 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11476 and sometimes 'EMACS_UINT', to represent these timestamps.
11477 This change causes it to use 'Time' uniformly, as that's what X uses.
11478 This makes the code easier to follow, and makes it easier to catch
11479 integer overflow bugs such as Bug#8664.
11480 * frame.c (Fmouse_position, Fmouse_pixel_position):
11481 Use Time, not unsigned long, for user-interface timestamps.
11482 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11483 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11484 * keyboard.h (last_event_timestamp): Likewise.
11485 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11486 * menu.h (xmenu_show): Likewise.
11487 * term.c (term_mouse_position): Likewise.
11488 * termhooks.h (struct input_event.timestamp): Likewise.
11489 (struct terminal.mouse_position_hook): Likewise.
11490 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11491 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11492 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11493 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11494 what it was before.
11495 * menu.h, termhooks.h: Include "systime.h", for Time.
11497 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11498 Don't assume that the difference between two unsigned long values
11499 can fit into an integer. At this point, we know button_down_time
11500 <= event->timestamp, so the difference must be nonnegative, so
11501 there's no need to cast the result if double-click-time is
11502 nonnegative, as it should be; check that it's nonnegative, just in
11503 case. This bug is triggered when events are more than 2**31 ms
11504 apart (about 25 days). (Bug#8664)
11506 * xselect.c (last_event_timestamp): Remove duplicate decl.
11507 (x_own_selection): Remove needless cast to unsigned long.
11509 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11510 that always fit in int. Use a sentinel instead of a counter, to
11511 avoid a temp and to allay GCC's concerns about possible int overflow.
11512 * frame.h (struct frame): Use int for menu_bar_items_used
11513 instead of EMACS_INT, since it always fits in int.
11515 * menu.c (grow_menu_items): Check for int overflow.
11517 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11519 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11520 Before, the code was not consistent. These values cannot exceed
11521 2**31 - 1 so there's no need to make them unsigned.
11522 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11523 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11524 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11525 as modifiers.
11526 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11528 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11529 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11530 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11531 presumably because the widths might not match.
11533 * window.c (size_window): Avoid needless test at loop start.
11535 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11537 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11539 2011-05-12 Drew Adams <drew.adams@oracle.com>
11541 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11543 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11545 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11546 `width' to `bar_area_x' and `bar_area_width', respectively.
11547 (x_scroll_run): Take account of fringe background extension.
11549 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11550 Rename local vars `left' and `width' to `bar_area_x' and
11551 `bar_area_width', respectively.
11552 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11553 background extension.
11555 2011-05-10 Jim Meyering <meyering@redhat.com>
11557 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11559 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11561 * image.c (Finit_image_library): Return t for built-in image types,
11562 like pbm and xbm. (Bug#8640)
11564 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11566 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11568 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11570 * w32console.c (Fset_screen_color): Doc fix.
11571 (Fget_screen_color): New function.
11572 (syms_of_ntterm): Defsubr it.
11574 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11575 unlink the temporary file if Fcall_process didn't create it in the
11576 first place.
11577 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11578 child process will be redirected to a file specified with `:file'.
11579 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11580 cue to call_process_cleanup not to close that handle.
11582 2011-05-07 Ben Key <bkey76@gmail.com>
11584 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11585 one of two shell specific rules, either bootstrap-temacs-CMD or
11586 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11587 to the previous implementation of the bootstrap-temacs rule.
11588 The bootstrap-temacs-CMD rule is similar to the previous
11589 implementation of the bootstrap-temacs rule except that it
11590 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11591 variable.
11593 These changes, along with some changes to nt/configure.bat,
11594 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11595 earlier fix to add support for --cflags and --ldflags options
11596 that include quotes so that it works whether make uses cmd or
11597 sh as the shell.
11599 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11601 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11602 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11603 is a constant.
11604 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11605 a string. Handle both cases.
11606 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11607 (Fdbus_register_method): Use Qinvalid_function.
11609 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11611 * makefile.w32-in: Update dependencies.
11612 (LISP_H): Add inttypes.h and stdin.h.
11613 (PROCESS_H): Add unistd.h.
11615 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11617 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11618 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11620 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11622 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11624 * term.c (vfatal): Remove stray call to va_end.
11625 It's not needed and the C Standard doesn't allow it here anyway.
11627 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11628 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11630 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11631 bytes.
11633 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11635 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11637 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11639 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11641 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11643 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11644 * charset.c (Fdefine_charset_internal): Don't initialize
11645 charset.code_space[15]. The value was garbage, on hosts with
11646 32-bit int (Bug#8600).
11648 * lread.c (read_integer): Be more consistent with string-to-number.
11649 Use string_to_number to do the actual conversion; this avoids
11650 rounding errors and fixes some other screwups. Without this fix,
11651 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11652 (digit_to_number): Move earlier, for benefit of read_integer.
11653 Return -1 if the digit is out of range for the base, -2 if it is
11654 not a digit in any supported base. (Bug#8602)
11656 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11658 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11659 to match comment at start of function. This also removes a
11660 GCC warning about overflow in a 32+64-bit port.
11662 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11664 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11665 Reported by Stefan Monnier in
11666 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11667 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11668 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11670 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11671 (EMACS_UINTPTR): Likewise, with uintptr_t.
11673 * lisp.h: Prefer 64-bit EMACS_INT if available.
11674 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11675 on 32-bit hosts that have 64-bit int, so that they can access
11676 large files.
11677 However, temporarily disable this change unless the temporary
11678 symbol WIDE_EMACS_INT is defined.
11680 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11682 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11683 This removes an assumption that EMACS_INT and long are the same
11684 width as pointers. The assumption is true for Emacs porting targets
11685 now, but we want to make other targets possible.
11686 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11687 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11688 In the rest of the code, change types of integers that hold casted
11689 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11690 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11691 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11692 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11693 No need to cast type when ORing.
11694 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11695 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11696 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11697 assume EMACS_INT is the same width as char *.
11698 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11699 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11700 Remove no-longer-needed casts.
11701 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11702 (xg_tool_bar_help_callback, xg_make_tool_item):
11703 Use EMACS_INTPTR to hold an integer
11704 that will be cast to void *; this can avoid a GCC warning
11705 if EMACS_INT is not the same width as void *.
11706 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11707 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11708 (current_message_1, set_message_1):
11709 Use a local to convert to proper width without a cast.
11710 * xmenu.c (dialog_selection_callback): Likewise.
11712 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11713 Also, don't assume VALBITS / RAND_BITS is less than 5,
11714 and don't rely on undefined behavior when shifting a 1 left into
11715 the sign bit.
11716 * lisp.h (get_random): Change signature to match.
11718 * lread.c (hash_string): Use size_t, not int, for hash computation.
11719 Normally we prefer signed values; but hashing is special, because
11720 it's better to use unsigned division on hash table sizes so that
11721 the remainder is nonnegative. Also, size_t is the natural width
11722 for hashing into memory. The previous code used 'int', which doesn't
11723 retain enough info to hash well into very large tables.
11724 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11726 * dbusbind.c: Don't possibly lose pointer info when converting.
11727 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11728 Use XPNTR rather than XHASH, so that the high-order bits of
11729 the pointer aren't lost when converting through void *.
11731 * eval.c (Fautoload): Don't double-shift a pointer.
11733 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11735 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11737 * gnutls.c (DEF_GNUTLS_FN):
11738 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11740 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11742 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11743 marker. (Bug#8610)
11745 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11747 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11748 New version that can reserve upto 2GB of heap space.
11750 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11752 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11754 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11756 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11757 `gnutls_certificate_set_x509_key_file'.
11759 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11761 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11762 Update dependencies.
11764 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11766 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11767 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11768 Remove unused parameter `fildes'.
11769 * process.c (read_process_output, send_process): Don't pass it.
11771 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11773 Fix previous change: the library cache is defined in w32.c.
11774 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11775 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11777 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11779 Implement dynamic loading of GnuTLS on Windows.
11781 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11782 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11783 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11784 Declare.
11786 * gnutls.c (Qgnutls_dll): Define.
11787 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11788 (gnutls_*): Declare function pointers.
11789 (init_gnutls_functions): New function to initialize function pointers.
11790 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11791 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11792 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11793 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11794 (emacs_gnutls_write, emacs_gnutls_read)
11795 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11796 (Fgnutls_available_p): New function.
11797 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11798 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11799 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11801 * image.c: Include w32.h.
11802 (Vimage_type_cache): Delete.
11803 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11804 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11805 (w32_delayed_load): Move to w32.c.
11807 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11809 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11810 (w32_delayed_load): Move from image.c. When loading a library, record
11811 its filename in the :loaded-from property of the library id.
11812 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11813 Initialize and staticpro them.
11814 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11816 * process.c: Include lisp.h before w32.h, not after.
11817 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11818 instead of gnutls_record_check_pending.
11820 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11822 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11824 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11825 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11826 as passed in.
11828 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11830 * xterm.c (x_set_frame_alpha): Do not set property on anything

11846 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
11847 (Qgnutls_bootprop_callbacks_verify): Make static.
11849 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11851 * callproc.c: Indentation fixup.
11853 * sysdep.c (wait_for_termination_1): Make static.
11854 (wait_for_termination, interruptible_wait_for_termination):
11855 Move after wait_for_termination_1.
11857 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11859 * sysdep.c (interruptible_wait_for_termination): New function
11860 which is like wait_for_termination, but allows keyboard
11861 interruptions.
11863 * callproc.c (Fcall_process): Add (:file "file") as an option for
11864 the STDOUT buffer.
11865 (Fcall_process_region): Ditto.
11867 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11869 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11870 rather than `XVECTOR (FOO)->size'.
11872 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11873 inttypes.h, as a gnulib replacement is used if it not available in
11874 system headers.
11876 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11878 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11879 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11880 of MOST_POSITIVE_FIXNUM. (Bug#8528)

11888 charbuf for the composition carryover bytes.
11890 2011-04-21 Eli Zaretskii <eliz@gnu.org>

11893 aborting when %lld or %lll format is passed.
11894 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11895 %llo or %llx format is passed. (Bug#8545)
11897 * window.c (window_scroll_line_based): Use a marker instead of
11898 simple variables to record original value of point. (Bug#7952)
11900 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11901 produced by %s or %c overflows available buffer space. (Bug#8545)
11903 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11905 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11906 (SIZE_MAX): Move defn after all includes, as they might #define it.
11908 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

11917 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11918 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11920 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11922 * doprnt.c (doprnt): Don't return value smaller than the buffer
11923 size if the message was truncated. (Bug#8545).
11925 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11927 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11928 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11930 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11932 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11934 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11936 * makefile.w32-in: Update dependencies.
11938 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11940 Improve `doprnt' and its usage. (Bug#8545)
11941 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11942 `format_end'. Remove support for %l as a conversion specifier.
11943 Don't use xrealloc. Improve diagnostics when the %l size modifier
11944 is used. Update the commentary.
11946 * eval.c (verror): Simplify calculation of size_t.
11948 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11949 messages.
11951 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11953 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11954 change.
11956 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11958 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11959 This makes this file independent of the recent pseudovector change.
11961 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11963 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11965 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11966 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11967 Remove unused local.
11968 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11970 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11971 GCC 4.6.0 optimizes based on type-based alias analysis.
11972 For example, if b is of type struct buffer * and v of type struct
11973 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11974 != &v->size, and therefore "v->size = 1; b->size = 2; return
11975 v->size;" must therefore return 1. This assumption is incorrect
11976 for Emacs, since it type-puns struct Lisp_Vector * with many other
11977 types. To fix this problem, this patch adds a new type struct
11978 vectorlike_header that documents the constraints on layout of vectors
11979 and pseudovectors, and helps optimizing compilers not get fooled
11980 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11981 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11982 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11983 the size member.
11984 (XSETPVECTYPE): Rewrite in terms of new macro.
11985 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11986 This is a bit clearer, and further avoids the possibility of
11987 undesirable aliasing.
11988 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11989 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11990 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11991 since Lisp_Subr is a special case (no "next" field).
11992 (ASIZE): Now uses header.size rather than size.
11993 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11994 to avoid the hassle of writing XVECTOR (foo)->header.size.
11995 (struct vectorlike_header): New type.
11996 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11997 object, to help avoid aliasing.
11998 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11999 (SUBRP): Likewise, since Lisp_Subr is a special case.
12000 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12001 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12002 (struct Lisp_Hash_Table): Combine first two members into a single
12003 struct vectorlike_header member. All uses of "size" and "next" members
12004 changed to be "header.size" and "header.next".
12005 * buffer.h (struct buffer): Likewise.
12006 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12007 * frame.h (struct frame): Likewise.
12008 * process.h (struct Lisp_Process): Likewise.
12009 * termhooks.h (struct terminal): Likewise.
12010 * window.c (struct save_window_data, struct saved_window): Likewise.
12011 * window.h (struct window): Likewise.
12012 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12013 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12014 * buffer.c (init_buffer_once): Likewise.
12015 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12016 special case.
12017 * process.c (Fformat_network_address): Use local var for size,
12018 for brevity.
12020 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12022 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12023 * data.c (atof): Remove decl; no longer used or needed.
12024 (digit_to_number): Move to lread.c.
12025 (Fstring_to_number): Use new string_to_number function, to be
12026 consistent with how the Lisp reader treats infinities and NaNs.
12027 Do not assume that floating-point numbers represent EMACS_INT
12028 without losing information; this is not true on most 64-bit hosts.
12029 Avoid double-rounding errors, by insisting on integers when
12030 parsing non-base-10 numbers, as the documentation specifies.
12031 * lisp.h (string_to_number): New decl, replacing ...
12032 (isfloat_string): Remove.
12033 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12034 (read1): Do not accept +. and -. as integers; this
12035 appears to have been a coding error. Similarly, do not accept
12036 strings like +-1e0 as floating point numbers. Do not report
12037 overflow for integer overflows unless the base is not 10 which
12038 means we have no simple and reliable way to continue.
12039 Break out the floating-point parsing into a new
12040 function string_to_number, so that Fstring_to_number parses
12041 floating point numbers consistently with the Lisp reader.
12042 (digit_to_number): Move here from data.c. Make it static inline.
12043 (E_CHAR, EXP_INT): Remove, replacing with ...
12044 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12045 (string_to_number): New function, replacing isfloat_string.
12046 This function checks for valid syntax and produces the resulting
12047 Lisp float number too. Rework it so that string-to-number
12048 no longer mishandles examples like "1.0e+". Use strtoumax,
12049 so that overflow for non-base-10 numbers is reported only when
12050 there's no portable and simple way to convert to floating point.
12052 * textprop.c (set_text_properties_1): Rewrite for clarity,
12053 and to avoid GCC warning about integer overflow.
12055 * intervals.h (struct interval): Use EMACS_INT for members
12056 where EMACS_UINT might cause problems. See
12057 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12058 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12059 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12060 All uses changed.
12061 (offset_intervals): Tell GCC not to worry about length overflow
12062 when negating a negative length.
12064 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12065 (overrun_check_free): Likewise.
12067 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12068 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12069 word size.
12071 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12072 (gnutls_make_error): Rename local to avoid shadowing.
12073 (gnutls_emacs_global_deinit): ifdef out; not used.
12074 (Fgnutls_boot): Use const for pointer to readonly storage.
12075 Comment out unused local. Fix pointer signedness problems.
12077 * lread.c (openp): Don't stuff size_t into an 'int'.
12078 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12079 about possible signed overflow.
12081 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12082 (GDK_KEY_g): Don't define if already defined.
12083 (xg_prepare_tooltip): Avoid pointer signedness problem.
12084 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12086 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12087 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12089 * xfns.c (Fx_window_property): Simplify a bit,
12090 to make a bit faster and to avoid GCC 4.6.0 warning.
12091 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12093 * fns.c (internal_equal): Don't assume size_t fits in int.
12095 * alloc.c (compact_small_strings): Tighten assertion a little.
12097 Replace pEd with more-general pI, and fix some printf arg casts.
12098 * lisp.h (pI): New macro, generalizing old pEd macro to other
12099 conversion specifiers. For example, use "...%"pI"d..." rather
12100 than "...%"pEd"...".
12101 (pEd): Remove. All uses replaced with similar uses of pI.
12102 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12103 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12104 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12105 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12106 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12107 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12108 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12109 64-bit hosts.
12110 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12111 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12112 * print.c (safe_debug_print, print_object): Likewise.
12113 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12114 to int.
12115 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12116 avoiding the 0 flag, which is not portable.
12117 * process.c (Fmake_network_process): Use pI to avoid cast.
12118 * region-cache.c (pp_cache): Likewise.
12119 * xdisp.c (decode_mode_spec): Likewise.
12120 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12121 behavior on 64-bit hosts with printf arg.
12122 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12123 (x_stop_queuing_selection_requests): Likewise.
12124 (x_get_window_property): Don't truncate byte count to an 'int'
12125 when tracing.
12127 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12128 here, since it parses constructs like leading '-' and spaces,
12129 which are not wanted; and it overflows with large numbers.
12130 Instead, simply match F[0-9]+, which is what is wanted anyway.
12132 * alloc.c: Remove unportable assumptions about struct layout.
12133 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12134 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12135 (allocate_vectorlike, make_pure_vector): Use the new macros,
12136 plus offsetof, to remove unportable assumptions about struct layout.
12137 These assumptions hold on all porting targets that I know of, but
12138 they are not guaranteed, they're easy to remove, and removing them
12139 makes further changes easier.
12141 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12142 This doesn't fix a bug but makes the code clearer.
12143 (string_overrun_cookie): Now const. Use initializers that
12144 don't formally overflow signed char, to avoid warnings.
12145 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12146 can cause Emacs to crash when string overrun checking is enabled.
12147 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12148 multiple of sizeof (EMACS_INT); it need not be, if
12149 alignof(EMACS_INT) < sizeof (EMACS_INT).
12150 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12152 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12154 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12156 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12158 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12159 supposed to be handshaking. (Bug#8556)
12160 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12162 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12164 * lisp.h (Qdebug): List symbol.
12165 * eval.c (Qdebug): Restore global linkage.
12166 * keyboard.c (debug-on-event): New variable.
12167 (handle_user_signal): Break into debugger when debug-on-event
12168 matches the current signal symbol.
12170 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12172 * alloc.c (check_sblock, check_string_bytes)
12173 (check_string_free_list): Convert to standard C.
12175 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12177 * w32.c (emacs_gnutls_push): Fix typo.
12179 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12181 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12182 "cast to pointer from integer of different size".
12184 Improve doprnt and its use in verror. (Bug#8545)
12185 * doprnt.c (doprnt): Document the set of format control sequences
12186 supported by the function. Use SAFE_ALLOCA instead of always
12187 using `alloca'.
12189 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12190 is one byte too soon. Don't use xrealloc; instead xfree and
12191 xmalloc anew.
12193 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12195 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12196 callbacks stage.
12198 * gnutls.c: Renamed global_initialized to
12199 gnutls_global_initialized. Added internals for the
12200 :verify-hostname-error, :verify-error, and :verify-flags
12201 parameters of `gnutls-boot' and documented those parameters in the
12202 docstring. Start callback support.
12203 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12204 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12205 on error. Return error code.
12206 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12207 (emacs_gnutls_read): Likewise.
12208 (Fgnutls_boot): Return handshake error code.
12209 (emacs_gnutls_handle_error): New function.
12210 (wsaerror_to_errno): Likewise.

12213 (emacs_gnutls_push): Likewise.
12215 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12216 (emacs_gnutls_push): Likewise.
12218 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12220 * process.c (wait_reading_process_output): Check if GnuTLS
12221 buffered some data internally if no FDs are set for TLS
12222 connections.

12233 commentary.
12235 * textprop.c (syms_of_textprop): Remove dead code.
12236 (copy_text_properties): Delete obsolete commentary about an
12237 interface that was deleted long ago. Fix typos in the description
12238 of arguments.

12241 to changes in oldXMenu/XMenu.h from 2011-04-16.
12242 <menu_help_message, prev_menu_help_message>: Constify.
12243 (IT_menu_make_room): menu->help_text is now `const char **';
12244 adjust.

12247 to changes in oldXMenu/XMenu.h from 2011-04-16.
12248 (struct XMenu): Declare `help_text' `const char **'.
12250 * xfaces.c <Qunspecified>: Make extern again.
12252 * syntax.c: Include sys/types.h before including regex.h, as
12253 required by POSIX.
12255 * doc.c (get_doc_string): Improve the format passed to `error'.
12257 * doprnt.c (doprnt): Improve commentary.
12259 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
12261 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
12262 them with etags.
12264 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
12265 changes in globals.h immediately force recompilation.
12266 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12267 $(CURDIR)/s/ms-w32.h.
12268 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
12270 * character.c (Fchar_direction): Function deleted.
12271 (syms_of_character): Don't defsubr it.
12272 <char-direction-table>: Deleted.
12274 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12276 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12277 * doprnt.c: Include limits.h.
12278 (SIZE_MAX): New macro.
12279 (doprnt): Return a size_t value. 2nd arg is now size_t.
12280 Many local variables are now size_t instead of int or unsigned.
12281 Improve overflow protection. Support `l' modifier for integer
12282 conversions. Support %l conversion. Don't assume an EMACS_INT
12283 argument for integer conversions and for %c.
12285 * lisp.h (doprnt): Restore prototype.
12287 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12288 $(SRC)/character.h.
12290 * Makefile.in (base_obj): Add back doprnt.o.
12292 * deps.mk (doprnt.o): Add back prerequisites.
12293 (callint.o): Depend on character.h.
12295 * eval.c (internal_lisp_condition_case): Include the handler
12296 representation in the error message.
12297 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12298 when breaking from the loop.
12300 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12302 * callint.c (Fcall_interactively): When displaying error message
12303 about invalid control letter, pass the character's codepoint, not
12304 a pointer to its multibyte form. Improve display of the character
12305 in octal and display also its hex code.
12307 * character.c (char_string): Use %x to display the (unsigned)
12308 codepoint of an invalid character, to avoid displaying a bogus
12309 negative value.
12311 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12312 `error', not SYMBOL_NAME itself.
12314 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12315 character arguments to `error'.
12317 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12318 to `error' in error message about FINAL_CHAR argument. Make sure
12319 FINAL_CHAR is a character, and use %c when it is passed as
12320 argument to `error'.
12322 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12324 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12326 * w32.c: Include <time.h>.

12346 to <= INT_MAX.
12348 2011-04-18 Chong Yidong <cyd@stupidchicken.com>
12350 * xdisp.c (lookup_glyphless_char_display)
12351 (produce_glyphless_glyph): Handle cons cell entry in

12371 * s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF): Protoize decl.
12373 * process.c (keyboard_bit_set): Define only if SIGIO.
12374 (send_process_trap): Mark it with NO_RETURN if it doesn't return.
12375 (send_process): Repair possible setjmp clobbering.

12509 * nsfont.m: Fixed bugs in ns_get_family and
12510 ns_descriptor_to_entity that were caused by using free to
12511 deallocate memory blocks that were allocated by xmalloc (via
12512 xstrdup). This caused Emacs to crash when compiled with
12513 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

12866 * buffer.c (buffer_count): Remove unused var.
12868 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
12869 so that it's not optimized away.
12870 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12871 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12872 exported only to the debugger.
12874 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12875 * atimer.h (run_all_atimers): Remove; not exported.
12877 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12878 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12879 was inaccessible from Lisp.
12880 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12881 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12883 alloc.c: Import and export fewer symbols, and remove unused items.
12884 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12885 is defined.
12886 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12887 it's not optimized away by whole-program optimization.
12888 (message_enable_multibyte, free_misc): Remove.
12889 (catchlist, handlerlist, mark_backtrace):
12890 Declare only if BYTE_MARK_STACK.

12892 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
12893 (message_enable_multibyte): Remove decl.

12899 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12900 (mark_backtrace): Define only if BYTE_MARK_STACK.
12901 * xdisp.c (message_enable_multibyte): Now static.
12903 Declare Lisp_Object Q* variables to be 'static' if not exported.
12904 This makes it easier for human readers (and static analyzers)
12905 to see whether these variables are used from other modules.
12906 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12907 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12908 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

12915 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12916 Remove decls of unexported vars.
12917 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12919 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12921 Make Emacs functions such as Fatom 'static' by default.
12922 This makes it easier for human readers (and static analyzers)
12923 to see whether these functions can be called from other modules.
12924 DEFUN now defines a static function. To make the function external
12925 so that it can be used in other C modules, use the new macro DEFUE.
12926 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12927 (Finit_image_library):
12928 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12929 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12930 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12931 Remove decls, since these functions are now static.
12932 (Funintern, Fget_internal_run_time): New decls, since these functions
12933 were already external.
12935 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12936 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12942 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12943 Mark functions with DEFUE instead of DEFUN,
12944 if they are used in other modules.
12945 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12946 decls for now-static functions.
12947 * buffer.h (Fdelete_overlay): Remove decl.
12948 * callproc.c (Fgetenv_internal): Mark as internal.
12949 * composite.c (Fremove_list_of_text_properties): Remove decl.

12957 * image.c (Finit_image_library): New forward static decl.
12958 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12959 * intervals.h (Fprevious_property_change):
12960 (Fremove_list_of_text_properties): Remove decls.
12961 * keyboard.c (Fthis_command_keys): Remove decl.
12962 (Fcommand_execute): New forward static decl.

12978 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12980 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12981 change. (Bug#8496)
12983 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12985 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12986 when at ZV. (Bug#8487)
12988 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12990 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12991 (Bug#8437)
12992 * keyboard.c (parse_tool_bar_item): Likewise.
12993 * sound.c (sound_cleanup, alsa_close): Likewise.
12994 * termcap.c (tgetent): Likewise.
12995 * xfns.c (x_default_font_parameter): Likewise.
12996 * xsettings.c (read_and_apply_settings): Likewise.
12998 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12999 (overrun_check_free): Protoize.
13001 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13003 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13004 since callers should never pass a negative size.
13005 Change the signature to match that of plain 'read' and 'write'; see
13006 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13007 * lisp.h: Update prototypes of emacs_write and emacs_read.
13009 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13011 * xdisp.c (redisplay_window): Don't try to determine the character
13012 position of the scroll margin if the window start point w->startp
13013 is outside the buffer's accessible region. (Bug#8468)
13015 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13017 Fix write-region and its subroutines for buffers > 2GB.
13018 * fileio.c (a_write, e_write): Modify declaration of arguments and
13019 local variables to support buffers larger than 2GB.
13020 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13022 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13023 argument, local variables, and return value.
13025 * lisp.h: Update prototypes of emacs_write and emacs_read.
13027 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13029 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13031 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13033 Fix more problems found by GCC 4.6.0's static checks.
13035 * xdisp.c (vmessage): Use a better test for character truncation.
13037 * charset.c (load_charset_map): <, not <=, for optimization,
13038 and to avoid potential problems with integer overflow.
13039 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13040 * casetab.c (set_identity, shuffle): Likewise.
13041 * editfns.c (Fformat): Likewise.
13042 * syntax.c (skip_chars): Likewise.
13044 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13045 This also lets GCC 4.6.0 generate slightly better loop code.
13047 * callint.c (Fcall_interactively): <, not <=, for optimization.
13048 (Fcall_interactively): Count the number of arguments produced,
13049 not the number of arguments given. This is simpler and lets GCC
13050 4.6.0 generate slightly better code.
13052 * ftfont.c: Distingish more carefully between FcChar8 and char.
13053 The previous code passed unsigned char * to a functions like
13054 strlen and xstrcasecmp that expect char *, which does not
13055 conform to the C standard.
13056 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13057 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13058 char * when the C standard requires it.
13060 * keyboard.c (read_char): Remove unused var.
13062 * eval.c: Port to Windows vsnprintf (Bug#8435).
13063 Include <limits.h>.
13064 (SIZE_MAX): Define if the headers do not.
13065 (verror): Do not give up if vsnprintf returns a negative count.
13066 Instead, grow the buffer. This ports to Windows vsnprintf, which
13067 does not conform to C99. Problem reported by Eli Zaretskii.
13068 Also, simplify the allocation scheme, by avoiding the need for
13069 calling realloc, and removing the ALLOCATED variable.
13071 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13073 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13074 But keep the doprint source code for now, as we might revamp it
13075 and use it again (Bug#8435).
13076 * lisp.h (doprnt): Remove.
13077 * Makefile.in (base_obj): Remove doprnt.o.
13078 * deps.mk (doprnt.o): Remove.
13080 error: Print 32- and 64-bit integers portably (Bug#8435).
13081 Without this change, on typical 64-bit hosts error ("...%d...", N)
13082 was used to print both 32- and 64-bit integers N, which relied on
13083 undefined behavior.
13084 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13085 * lisp.h (error, verror): Mark as printf-like functions.
13086 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13087 Report overflow in size calculations when allocating printf buffer.
13088 Do not truncate output string at its first null byte.
13089 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13090 Truncate the output at a character boundary, since vsnprintf does not
13091 do that.
13092 * charset.c (check_iso_charset_parameter): Convert internal
13093 character to string before calling 'error', since %c now has the
13094 printf meaning.
13095 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13096 overflow when computing char to be passed to 'error'. Do not
13097 pass Lisp_Object to 'error'; pass the integer instead.
13098 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13099 formatted with plain %d.
13101 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13103 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13105 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13107 * xterm.c (x_catch_errors): Remove duplicate declaration.
13109 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13111 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13113 2011-04-10 Jim Meyering <meyering@redhat.com>
13115 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13116 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13117 return ssize_t not "int", and use size_t as the buffer length.
13118 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13119 * gnutls.h: Update declarations.
13120 * process.c (read_process_output): Use ssize_t, to match.
13121 (send_process): Likewise.
13123 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13125 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13127 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13129 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13130 Use unsigned char, to match FcChar8 type definition.
13132 * xterm.c (handle_one_xevent):
13133 * xmenu.c (create_and_show_popup_menu):
13134 * xselect.c (x_decline_selection_request)
13135 (x_reply_selection_request): Avoid type-punned deref of X events.
13137 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13139 Fix some uses of `int' instead of EMACS_INT.
13140 * search.c (string_match_1, fast_string_match)
13141 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13142 (scan_buffer, find_next_newline_no_quit)
13143 (find_before_next_newline, search_command, Freplace_match)
13144 (Fmatch_data): Make some `int' variables be EMACS_INT.
13146 * xdisp.c (display_count_lines): 3rd argument and return value now
13147 EMACS_INT. All callers changed.
13148 (pint2hrstr): Last argument is now EMACS_INT.
13150 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13151 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13152 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13153 (decode_coding_utf_16, decode_coding_emacs_mule)
13154 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13155 (decode_coding_ccl, decode_coding_charset)
13156 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13157 (decode_coding_iso_2022, decode_coding_emacs_mule)
13158 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13159 <char_offset, last_offset>: Declare EMACS_INT.
13160 (encode_coding_utf_8, encode_coding_utf_16)
13161 (encode_coding_emacs_mule, encode_invocation_designation)
13162 (encode_designation_at_bol, encode_coding_iso_2022)
13163 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13164 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13165 Declare EMACS_INT.
13166 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13167 (encode_invocation_designation): Last argument P_NCHARS is now
13168 EMACS_INT.
13169 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13170 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13172 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13173 All users changed.
13175 * ccl.c (Fccl_execute_on_string): Declare some variables
13176 EMACS_INT.
13178 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13180 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13182 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13184 * process.c (Fformat_network_address): Doc fix.
13186 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13188 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13190 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13192 * keyboard.c (read_char): Call Lisp function help-form-show,
13193 instead of using internal_with_output_to_temp_buffer.
13194 (Qhelp_form_show): New var.
13195 (syms_of_keyboard): Use DEFSYM macro.
13197 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13199 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13201 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13203 * process.c (Flist_processes): Remove to Lisp.
13204 (list_processes_1): Delete.
13206 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13208 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13210 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13212 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13214 Fix more problems found by GCC 4.6.0's static checks.
13216 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13218 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13220 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13222 * xdisp.c (vmessage): Mark as a printf-like function.
13224 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13226 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13228 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13229 printf-like functions.
13230 (tiff_load): Add casts to remove these marks before passing them
13231 to system-supplied API.
13233 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13235 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13236 This avoids several warnings with gcc -Wstrict-overflow.
13237 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13238 directly, rather than having caller test rule sign. This avoids
13239 some unnecessary tests.
13240 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13241 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13242 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13244 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13245 (xfont_open): Avoid unnecessary tests.
13247 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13249 * composite.h, composite.c (composition_gstring_put_cache):
13250 Use EMACS_INT, not int, for length.
13252 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13253 breaking out part of COMPOSITION_DECODE_RULE.
13254 (COMPOSITION_DECODE_RULE): Use it.
13255 * composite.c (get_composition_id): Remove unused local vars,
13256 by using the new macro.
13258 * textprop.c (set_text_properties_1): Change while to do-while,
13259 since the condition is always true at first.
13261 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13262 (interval_deletion_adjustment): Return unsigned value.
13263 All uses changed.
13265 * process.c (list_processes_1, create_pty, read_process_output):
13266 (exec_sentinel): Remove vars that were set but not used.
13267 (create_pty): Remove unnecessary "volatile"s.
13268 (Fnetwork_interface_info): Avoid possibility of int overflow.
13269 (read_process_output): Do adaptive read buffering even if carryover.
13270 (read_process_output): Simplify nbytes computation if buffered.
13272 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
13274 * syntax.c (scan_words): Remove var that was set but not used.
13275 (update_syntax_table): Use unsigned instead of int.
13277 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13278 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13279 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13281 * print.c (print_error_message): Avoid int overflow.
13283 * font.c (font_list_entities): Redo for clarity,
13284 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13286 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13287 (font_score): Avoid potential overflow in diff calculation.
13289 * fns.c (substring_both): Remove var that is set but not used.
13290 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13292 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13294 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13295 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13296 can always succeed if overflow has undefined behavior.
13298 * search.c (boyer_moore, wordify): Remove vars set but not used.
13299 (wordify): Omit three unnecessary tests.
13301 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13302 All callers changed. This avoids the need for an unused var.
13304 * casefiddle.c (casify_region): Remove var that is set but not used.
13306 * dired.c (file_name_completion): Remove var that is set but not used.
13308 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13310 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13311 (Finsert_file_contents): Remove unnecessary code checking fd.
13313 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13314 Check for integer overflow on size calculations.
13316 * buffer.c (Fprevious_overlay_change): Remove var that is set
13317 but not used.
13319 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13320 Remove vars that are set but not used.
13321 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13322 (timer_check_2): Mark vars as initialized.
13324 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13326 * image.c (lookup_image): Remove var that is set but not used.
13327 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13329 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13330 that are set but not used.
13332 * xfns.c (make_invisible_cursor): Don't return garbage
13333 if XCreateBitmapFromData fails (Bug#8410).
13335 * xselect.c (x_get_local_selection, x_handle_property_notify):
13336 Remove vars that are set but not used.
13338 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13339 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13341 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13342 Remove var that is set but not used.
13343 (scroll_bar_windows_size): Now size_t, not int.
13344 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13345 Check for overflow.
13347 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13348 (map_tty_color) [!defined MSDOS]: Likewise.
13350 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13352 * coding.c: Remove vars that are set but not used.
13353 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13354 All callers changed.
13355 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13356 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13357 (decode_coding_charset): Remove vars that are set but not used.
13359 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13360 that is set but not used.
13362 * print.c (print_object): Remove var that is set but not used.
13364 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13365 The gnulib version avoids calling malloc in the usual case,
13366 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13367 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13368 * filelock.c (current_lock_owner): Likewise.
13369 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13370 * sysdep.c: Include allocator.h, careadlinkat.h.
13371 (emacs_no_realloc_allocator): New static constant.
13372 (emacs_readlink): New function.
13373 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13374 ../lib/careadlinkat.h.
13376 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13378 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13379 first non-nil return value).
13381 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13383 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13384 if not defined (Bug#8403).
13386 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13388 * xdisp.c (display_count_lines): Remove parameter `start',
13389 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13390 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13391 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13392 (fill_stretch_glyph_string): Remove parameters `row' and `area',
13393 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13394 and thereabouts. All callers changed.
13395 (get_per_char_metric): Remove parameter `f', unused since
13396 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13398 2011-04-02 Jim Meyering <meyering@redhat.com>
13400 do not dereference NULL upon failed strdup
13401 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13402 (ns_get_family): Likewise.
13404 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13406 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13408 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13410 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13411 later (Bug#8403).
13413 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13415 Add lexical binding.
13417 * window.c (Ftemp_output_buffer_show): New fun.
13418 (Fsave_window_excursion):
13419 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13421 * lread.c (lisp_file_lexically_bound_p): New function.
13422 (Fload): Bind Qlexical_binding.
13423 (readevalloop): Remove `evalfun' arg.
13424 Bind Qinternal_interpreter_environment.
13425 (Feval_buffer): Bind Qlexical_binding.
13426 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13427 Mark as dynamic.
13428 (syms_of_lread): Declare `lexical-binding'.
13430 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13432 * keyboard.c (eval_dyn): New fun.
13433 (menu_item_eval_property): Use it.
13435 * image.c (parse_image_spec): Use Ffunctionp.
13437 * fns.c (concat, mapcar1): Accept byte-code-functions.
13439 * eval.c (Fsetq): Handle lexical vars.
13440 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13441 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13442 (FletX, Flet): Obey lexical binding.
13443 (Fcommandp): Handle closures.
13444 (Feval): New `lexical' arg.
13445 (eval_sub): New function extracted from Feval. Use it almost
13446 everywhere where Feval was used. Look up vars in lexical env.
13447 Handle closures.
13448 (Ffunctionp): Move from subr.el.
13449 (Ffuncall): Handle closures.
13450 (apply_lambda): Remove `eval_flags'.
13451 (funcall_lambda): Handle closures and new byte-code-functions.
13452 (Fspecial_variable_p): New function.
13453 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13454 but without exporting it to Lisp.
13456 * doc.c (Fdocumentation, store_function_docstring):
13457 * data.c (Finteractive_form): Handle closures.
13459 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13460 interactive spec.
13462 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13463 New byte-codes.
13464 (exec_byte_code): New function extracted from Fbyte_code to handle new
13465 calling convention for byte-code-functions. Add new byte-codes.
13467 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13469 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13471 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13473 * xdisp.c (redisplay_internal): Fix prototype.
13475 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13477 * xdisp.c (SCROLL_LIMIT): New macro.
13478 (try_scrolling): Use it when setting scroll_limit.
13479 Limit scrolling to 100 screen lines.
13480 (redisplay_window): Even when falling back on "recentering",
13481 position point in the window according to scroll-conservatively,
13482 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13484 (try_scrolling): When point is above the window, allow searching
13485 as far as scroll_max, or one screenful, to compute vertical
13486 distance from PT to the scroll margin position. This prevents
13487 try_scrolling from unnecessarily failing when
13488 scroll-conservatively is set to a value slightly larger than the
13489 window height. Clean up the case of PT below the margin at bottom
13490 of window: scroll_max can no longer be INT_MAX. When aggressive
13491 scrolling is in use, don't let point enter the opposite scroll
13492 margin as result of the scroll.
13493 (syms_of_xdisp) <scroll-conservatively>: Document the
13494 threshold of 100 lines for never-recentering scrolling.
13496 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13498 * dispextern.h (move_it_by_lines):
13499 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13500 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13501 (message_log_check_duplicate): Remove parameters `prev_bol' and
13502 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13503 (redisplay_internal): Remove parameter `preserve_echo_area',
13504 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13506 * indent.c (Fvertical_motion):
13507 * window.c (window_scroll_pixel_based, Frecenter):
13508 Don't pass `need_y_p' to `move_it_by_lines'.
13510 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13512 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13513 steal a few bits to be more compact.
13514 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13515 Remove unneeded casts.
13517 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13519 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13521 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13522 binding" message (bug#7967).
13524 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13526 Fix more problems found by GCC 4.6.0's static checks.
13528 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13529 Remove unused local var.
13531 * editfns.c (Fmessage_box): Remove unused local var.
13533 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13534 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13535 Omit unused local vars.
13536 * window.c (shrink_windows): Omit unused local var.
13537 * menu.c (digest_single_submenu): Omit unused local var.
13538 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13539 Omit unused local var.
13541 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13542 Don't assume string length fits in int.
13543 (keyremap_step, read_key_sequence): Use size_t for sizes.
13544 (read_key_sequence): Don't check last_real_key_start redundantly.
13546 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13547 instead of alloca (Bug#8344).
13549 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13550 (Fbacktrace_frame): Don't assume nframes fits in int.
13552 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13554 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13555 concerns.
13557 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13559 * cm.c (calccost): Turn while-do into do-while, for clarity.
13561 * keyboard.c (syms_of_keyboard): Use the same style as later
13562 in this function when indexing through an array. This also
13563 works around GCC bug 48267.
13565 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13567 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13569 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13570 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13572 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13573 This avoids undefined behavior on integer overflow, and is a bit
13574 more convenient anyway since it is compared to a size_t variable.
13576 Variadic C functions now count arguments with size_t, not int.
13577 This avoids an unnecessary limitation on 64-bit machines, which
13578 caused (substring ...) to crash on large vectors (Bug#8344).
13579 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13580 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13581 All variadic functions and their callers changed accordingly.

13586 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13587 (funcall_lambda, mark_backtrace): Likewise.
13588 * fns.c (concat): Likewise.
13589 * frame.c (x_set_frame_parameters): Likewise.
13590 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13591 0 if not found, not -1. All callers changed.
13593 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13594 (stack_copy_size): Now size_t, not int.
13595 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13597 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13599 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13600 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13601 All callers changed.
13603 * lisp.h (multibyte_char_to_unibyte):
13604 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13605 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13606 * character.h (CHAR_TO_BYTE8):
13607 * cmds.c (internal_self_insert):
13608 * editfns.c (general_insert_function):
13609 * keymap.c (push_key_description):
13610 * search.c (Freplace_match):
13611 * xdisp.c (message_dolog, set_message_1): All callers changed.
13613 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13615 * keyboard.c (safe_run_hook_funcall): New function.
13616 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13617 don't set the hook to nil, but remove the offending function instead.
13618 (Qcommand_hook_internal): Remove, unused.
13619 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13620 Vcommand_hook_internal.
13622 * eval.c (enum run_hooks_condition): Remove.
13623 (funcall_nil, funcall_not): New functions.
13624 (run_hook_with_args): Call each function through a `funcall' argument.
13625 Remove `cond' argument, now redundant.
13626 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13627 (Frun_hook_with_args_until_failure): Adjust accordingly.
13628 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13630 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

13634 * print.c (strout): Remove parameter `multibyte', unused since
13635 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13637 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13638 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13639 All callers changed.
13641 * w32.c (_wsa_errlist): Use braces for struct initializers.
13643 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13644 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13645 All callers changed.

13802 Use Frun_hooks.
13803 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

13806 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13808 Fix more problems found by GCC 4.5.2's static checks.
13810 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13811 the first time through the loop, since we know p0 < p1 then.
13812 This also avoids a gcc -Wstrict-overflow warning.
13814 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13815 leading to a memory leak, possible in functions like
13816 load_charset_map_from_file that can allocate an unbounded number
13817 of objects (Bug#8318).
13819 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13820 that could (at least in theory) be that large.
13822 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13823 This is less likely to overflow, and avoids undefined behavior if
13824 overflow does occur. All callers changed. Use strtoul to scan
13825 for the unsigned long integer.
13826 (pint2hrstr): Simplify and tune code slightly.
13827 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13840 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13842 * process.c (Fmake_network_process): Use socklen_t, not int,
13843 where POSIX says socklen_t is required in portable programs.
13844 This fixes a porting bug on hosts like 64-bit HP-UX, where
13845 socklen_t is wider than int (Bug#8277).
13846 (Fmake_network_process, server_accept_connection):
13847 (wait_reading_process_output, read_process_output):
13848 Likewise.

13860 Make tparam.h and terminfo.c consistent.
13861 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13862 Include tparam.h instead, since it declares them.
13863 * cm.h (PC): Remove extern decl; tparam.h now does this.
13864 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13865 * terminfo.c: Include tparam.h, to check interfaces.
13866 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13867 (tparam): Adjust signature to match interface in tparam.h;
13868 this removes some undefined behavior. Check that outstring and len
13869 are zero, which they always are with Emacs.
13870 * tparam.h (PC, BC, UP): New extern decls.
13872 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13873 (xftfont_open): Rename locals to avoid shadowing.

13887 * composite.c (composition_compute_stop_pos): Rename local to
13888 avoid shadowing.
13889 (composition_reseat_it): Remove unused locals.
13890 (find_automatic_composition, composition_adjust_point): Likewise.
13891 (composition_update_it): Mark var as initialized.

13897 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13898 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13899 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13900 to avoid shadowing.
13902 * textprop.c (property_change_between_p): Remove; unused.

13912 Fix pointer signedness.
13913 (alsa_choose_format): Remove unused local var.
13914 (wav_play): Initialize a variable to 0, to prevent undefined
13915 behavior (Bug#8278).
13917 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13919 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13921 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13922 clobbering (Bug#8298).
13923 * sysdep.c (sys_subshell): Likewise.
13924 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13926 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13927 This should get cleaned up, so that child_setup has the
13928 same signature on all platforms.
13930 * callproc.c (call_process_cleanup): Now static.
13931 (relocate_fd): Rename locals to avoid shadowing.
13933 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13935 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13936 not to be necessary, and produces flickering.
13938 2011-03-20 Glenn Morris <rgm@gnu.org>
13940 * config.in: Remove file.
13942 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

13987 Define only if needed.
13989 * unexelf.c (unexec): Name an expression,
13990 to avoid gcc -Wbad-function-cast warning.
13991 Use a different way to cause a compilation error if anyone uses
13992 n rather than nn, a way that does not involve shadowing.
13993 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13995 * deps.mk (unexalpha.o): Remove; unused.

14086 they're used.
14087 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

14103 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14104 EMACS_INT, since callers assume the returned value fits in int.
14105 (upcase1): Likewise, for UPCASE_TABLE.
14106 (uppercasep, lowercasep, upcase): New static inline functions.
14107 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14108 the race-condition problem in the old DOWNCASE.
14110 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14111 Rename locals to avoid shadowing.
14112 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14113 (regex_compile, re_search_2, re_match_2_internal):
14114 Remove unused local vars.
14115 (FREE_VAR): Rewrite so as not to use empty "else",
14116 which gcc can warn about.
14117 (regex_compile, re_match_2_internal): Mark locals as initialized.
14118 (RETALLOC_IF): Define only if needed.
14119 (WORDCHAR_P): Likewise. This one is never needed, but is used
14120 only in a comment talking about a compiler bug, so put inside
14121 the #if 0 of that comment.
14122 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14123 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14124 Remove; unused.
14126 * search.c (boyer_moore): Rename locals to avoid shadowing.
14127 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14128 (PREV_CHAR_BOUNDARY): Likewise.
14130 * search.c (simple_search): Remove unused var.
14132 * dired.c (compile_pattern): Move decl from here ...
14133 * lisp.h: ... to here, so that it can be checked.
14134 (struct re_registers): New forward decl.
14136 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
14138 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14139 All uses changed.
14140 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14141 Rename locals to avoid shadowing.
14142 (Fvertical_motion): Mark locals as initialized.
14144 * casefiddle.c (casify_object, casify_region): Now static.

14149 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14150 New macros, so that the caller can use some names other than
14151 gcpro1, gcpro2, etc.
14152 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14153 of the new macros.
14154 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14155 argument, for consistency with GCPRO2_VAR, etc: it is now the
14156 prefix of the variable, not the variable itself. All uses
14157 changed.
14158 * dired.c (directory_files_internal, file_name_completion):
14159 Rename locals to avoid shadowing.
14161 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14162 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14163 dired.c's scmp function, had undefined behavior.
14164 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14165 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14166 * buffer.h: ... to here, because these macros use current_buffer,
14167 and the new implementation with inline functions needs to have
14168 current_buffer in scope now, rather than later when the macros
14169 are used.
14170 (downcase, upcase1): New static inline functions.
14171 (DOWNCASE, UPCASE1): Reimplement using these functions.
14172 This avoids undefined behavior in expressions like
14173 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14174 from race conditions in accessing the global variables
14175 case_temp1 and case_temp2.
14176 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14177 * lisp.h (case_temp1, case_temp2): Remove their decls.
14178 * character.h (ASCII_CHAR_P): Move from here ...
14179 * lisp.h: ... to here, so that the inline functions mentioned
14180 above can use them.
14182 * dired.c (directory_files_internal_unwind): Now static.
14184 * fileio.c (file_name_as_directory, directory_file_name):
14185 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14186 Now static.
14187 (file_name_as_directory): Use const pointers when appropriate.
14188 (Fexpand_file_name): Likewise. In particular, newdir might
14189 point at constant storage, so make it a const pointer.
14190 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14191 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14192 signedness issues.
14193 (Fset_file_times, Finsert_file_contents, auto_save_error):
14194 Rename locals to avoid shadowing.

14197 (Ftry_completion, Fall_completions): Rename or remove locals
14198 to avoid shadowing.
14200 * marker.c (bytepos_to_charpos): Remove; unused.
14202 * lisp.h (verify_bytepos, count_markers): New decls,
14203 so that gcc does not warn that these functions aren't declared.
14205 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14206 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14207 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14208 (copy_text): Remove unused local var.
14210 * filelock.c (within_one_second): Now static.
14211 (lock_file_1): Rename local to avoid shadowing.
14213 * buffer.c (fix_overlays_before): Mark locals as initialized.
14214 (fix_start_end_in_overlays): Likewise. This function should be
14215 simplified by using pointers-to-pointers, but that's a different
14216 matter.
14217 (switch_to_buffer_1): Now static.
14218 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14219 (report_overlay_modification): Rename locals to avoid shadowing.
14221 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14222 Fix pointer signedness issue.
14223 (sys_subshell): Mark local as volatile if checking for lint,
14224 to suppress a gcc -Wclobbered warning that does not seem to be right.
14225 (MAXPATHLEN): Define only if needed.
14227 * process.c (serial_open, serial_configure): Move decls from here ...
14228 * systty.h: ... to here, so that they can be checked.
14230 * fns.c (get_random, seed_random): Move extern decls from here ...
14231 * lisp.h: ... to here, so that they can be checked.
14233 * sysdep.c (reset_io): Now static.
14234 (wait_for_termination_signal): Remove; unused.
14236 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14237 (copy_keymap_item, append_key, push_text_char_description):
14238 Now static.
14239 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14240 (DENSE_TABLE_SIZE): Remove; unused.
14241 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14242 (describe_map_tree):

14262 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
14263 (DEFINE_DUMMY_FUNCTION): New macro.

14272 (xd_signature, xd_append_arg, xd_initialize):
14273 (Fdbus_call_method, Fdbus_call_method_asynchronously):

14393 1152921504606846976) returns the obviously-bogus value (-948597
14394 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
