429 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from

431 the fix for 12036 would have avoided some of the problems noted in
432 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems

444 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
445 not be usable in #if. This simplifies things.
447 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
449 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
451 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

456 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
457 Adjust to changes in lisp.h and emacs.c, by using
458 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead

460 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
461 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS

1365 * nsterm.m: Include <ftoastr.h>.
1367 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1368 Prefer snprintf to strncpy.
1369 * nsterm.m (ns_term_init):
1370 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1371 * nsterm.m (ns_term_init):
1372 Avoid the need for strncpy, by using build_string or
1373 make_unibyte_string directly. Use dtoastr, not snprintf.
1374 * process.c (Fmake_network_process): Diagnose service names that
1375 are too long, rather than silently truncating them or creating
1376 non-null-terminated names.

1406 Optimize pure C strings initialization.
1407 * lisp.h (make_pure_string): Fix prototype.
1408 (build_pure_c_string): New function, defined as static inline. This
1409 provides a better opportunity to optimize away calls to strlen when
1410 the function is called with compile-time constant argument.
1411 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1412 argument, adjust users accordingly. Use build_pure_c_string where
1414 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1415 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1416 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1418 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1420 Avoid calls to strlen in miscellaneous functions.
1421 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1422 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1423 * lread.c (openp): Likewise.
1425 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1427 Avoid calls to strlen in path processing functions.
1428 * fileio.c (file_name_as_directory): Add comment. Change to add
1429 srclen argument and return the length of result. Adjust users
1431 (directory_file_name): Fix comment. Change to add srclen argument,

1434 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1436 2012-07-10 Glenn Morris <rgm@gnu.org>
1438 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1439 Move PENDING_OUTPUT_COUNT definition to configure.

1443 * s/gnu.h (DATA_START): Move definitions to configure.
1445 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1446 We include usg5-4-common.h, which defines them both.
1448 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1449 O_RDONLY already includes it).
1451 Stop ns builds setting the EMACSLOADPATH environment variable.
1452 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1453 Now it does not set EMACSLOADPATH, just returns the load-path string.
1454 * nsterm.h: Update accordingly.
1455 * lread.c [HAVE_NS]: Include nsterm.h.
1456 (init_lread) [HAVE_NS]: Use ns_load_path.

1459 2012-07-09 Glenn Morris <rgm@gnu.org>
1461 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1462 since the included bsd-common.h does so.
1464 Stop ns builds setting the EMACSPATH environment variable.
1465 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1466 (ns_init_paths): Do not set EMACSPATH.
1467 * nsterm.h (ns_exec_path): Add it.
1468 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1471 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1473 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1475 * process.c (wait_reading_process_output): 'waitchannels' was unset
1476 when read_kbd || !NILP (wait_for_cell); fix this.
1478 Add GCC-style 'const' attribute to functions that can use it.
1479 * character.h (char_resolve_modifier_mask):
1480 * keyboard.h (make_ctrl_char):
1481 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1490 Add decls with ATTRIBUTE_CONST.
1492 Minor improvements to make_formatted_string.
1493 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1494 where int is good enough, as vsprintf returns an int.
1495 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1497 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1499 Use make_formatted_string to avoid double length calculation.
1500 * lisp.h (make_formatted_string): New prototype.

1524 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1526 Move marker debugging code under MARKER_DEBUG.
1527 * marker.c (MARKER_DEBUG): Move marker debugging code under
1528 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1529 for bootstrap with --enable-checking (~3x slowdown reported
1530 by Juanma Barranquero <lekktu@gmail.com>).
1531 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1533 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1535 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1536 See <http://bugs.gnu.org/11825#29>.
1538 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1540 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1541 has no font, use the frame's font. (Bug#11813)
1542 (display_line): Add commentary about displaying truncation glyphs
1544 (produce_special_glyphs): Move here from term.c.
1546 * term.c (produce_special_glyphs): Move to xdisp.c.
1548 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1551 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1553 * xdisp.c (display_line): Avoid warning about implicit declaration
1556 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1558 * lisp.h: Remove empty conditional.
1560 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1562 * lread.c (load_path_check): Now static.
1564 Fix some minor --with-ns problems found by static checking.
1565 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1566 (x_set_font) [!HAVE_X_WINDOWS]:
1567 * image.c (xpm_load_image) [HAVE_NS]:
1568 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1569 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1570 Remove unused local.
1571 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1572 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1573 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1574 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1575 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1576 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1577 Fix pointer signedness problem.
1578 * xfaces.c (FRAME_X_FONT_TABLE):
1579 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1581 2012-07-07 Glenn Morris <rgm@gnu.org>
1583 * lread.c (load_path_check): New function, split from init_lread.
1584 (init_lread): Reorganize. Motivation:
1585 If EMACSLOADPATH is set, check/warn about that rather than the
1586 defaults, which we are not going to use. Hence we can remove
1587 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1588 Don't warn if site-lisp directories are missing.
1589 If not installed, start from a blank load-path, since
1590 PATH_LOADSEARCH refers to the eventual installation directories.
1592 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1594 Support truncation and continuation glyphs on GUI frames, when
1595 fringes are disabled. (Bug#11832)
1596 * xdisp.c (init_iterator): Get dimensions of truncation and
1597 continuation glyphs even if on GUI frames. Adjust
1598 it->last_visible_x on GUI frames when the left or right fringes,
1599 or both, are absent.
1600 (start_display, move_it_in_display_line_to): Handle the case of a
1601 GUI frame without a fringe to display continuation or truncation
1603 (insert_left_trunc_glyphs): Support GUI frames: make sure
1604 truncation glyphs overwrite enough glyphs from the current line to
1605 have sufficient space in pixels.
1606 (display_line): Support truncation and continuation glyphs on GUI
1607 frames. If some spare pixels are left on the line after inserting
1608 the truncation glyphs, fill that space with a stretch glyph of a
1609 suitably computed width.
1611 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1612 produce_glyphs, to support GUI sessions.
1614 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1616 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1618 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1620 Do not require float-time's arg to fit in time_t (Bug#11825).
1621 This works better on hosts where time_t is unsigned, and where
1622 float-time is applied to the (negative) difference between two times.
1623 * editfns.c (decode_time_components): Last arg is now double *,
1624 not int *, and means to store all the result as a double, without
1625 worrying about whether the seconds part fits in time_t.
1626 All callers changed.
1627 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1628 All callers changed.
1629 (Ffloat_time): Do not fail merely because the specified time falls
1630 outside of time_t range.
1632 2012-07-07 Glenn Morris <rgm@gnu.org>
1634 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1640 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1641 Update dependencies.
1643 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1645 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

1649 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1650 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1651 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

1654 * xfont.c (compare_font_names): Redo to omit the need for casts.
1656 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1658 * xfns.c (Fx_change_window_property): Doc fix.
1659 * w32fns.c (Fx_change_window_property): Doc fix.
1661 * w32fns.c (Fx_window_property): Accept the same arguments as the
1662 X Windows version. Doc fix.
1663 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1665 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1666 Eli Zaretskii <eliz@gnu.org>
1668 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1669 Windows-specific code from nt/config.nt moved here.
1670 Obsolete settings removed.
1672 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1674 * process.c: Avoid unnecessary calls to gettime.
1675 (wait_reading_process_output): Don't get the time of day
1676 when gobbling data immediately and not waiting, as there's no need
1677 for it in that case. This removes a FIXME.
1679 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1681 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1682 is defined (Bug#11768).
1684 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1686 Fix marker debugging code.
1687 * marker.c (byte_char_debug_check): Do not perform the check
1688 if buffer is not multibyte.
1689 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1690 Call byte_char_debug_check with correct arguments.
1692 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1694 Compile marker debugging code only if ENABLE_CHECKING is defined.
1695 * marker.c (byte_char_debug_check, count_markers):
1696 Use only if ENABLE_CHECKING is defined.
1697 (byte_debug_flag): Remove.
1698 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1699 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1701 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1703 Avoid code repetition in marker-related functions.
1704 * marker.c (attach_marker): New function.
1705 (Fset_marker, set_marker_restricted, set_marker_both)
1706 (set_marker_restricted_both): Use it.
1707 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1708 Consistently rename charno to charpos.
1709 (marker_position): Add eassert.
1710 (marker_byte_position): Convert to eassert.

1729 * window.c (save_window_save): Likewise.
1731 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1733 Do not use Fdelete_overlay in delete_all_overlays
1734 to avoid redundant calls to unchain_overlay.
1735 * buffer.c (drop_overlay): New function.
1736 (delete_all_overlays, Fdelete_overlay): Use it.
1737 * minibuf.c (get_minibuffer): Fix comment.
1739 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1741 Port to OpenBSD 5.1 amd64.
1742 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1743 This is needed for OpenBSD, and should be harmless on all BSD systems.
1744 Also, include <sys/sysctl.h>, as it should be available on all
1745 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1746 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1747 use p_pid member, not kp_proc.pid.
1749 2012-07-06 Glenn Morris <rgm@gnu.org>
1751 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1753 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1755 More xmalloc and related cleanup.

1764 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1766 Omit needless casts involving void * pointers and allocation.
1767 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1768 as the former is more robust if P's type is changed.
1769 Prefer xzalloc to xmalloc + memset 0.
1770 Simplify malloc-or-realloc to realloc.
1771 Don't worry about xmalloc returning a null pointer.
1772 Prefer xstrdup to xmalloc + strcpy.
1773 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1775 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1776 alloca of a constant.
1778 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1780 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1781 hscroll is larger than the line width. Fixes long and futile
1782 looping inside extend_face_to_end_of_line (on a TTY) producing
1783 glyphs that are not needed and thrown away.
1785 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1787 * marker.c (set_marker_restricted_both): Simplify by using

1813 * xdisp.c (window_hscroll_limited): New function.
1814 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1815 coordinates when window's hscroll is set to insanely large
1818 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1820 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1821 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

1882 Problem reported by Troels Nielsen in
1883 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1885 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1887 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1888 This should be fixed in a better way; see Eli Zaretskii in
1889 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1890 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1892 * fileio.c (time_error_value): Rename from special_mtime.
1893 The old name's problems were noted by Eli Zaretskii in
1894 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1896 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1897 This variable's comment says Emacs needs at least one GDB-visible
1898 symbol of type enum pvec_type, to work around GDB problems.
1899 The symbol's value doesn't matter.
1901 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1902 that causes compilation to fail on pre-C99 compilers.

1917 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1918 * lisp.h (enum pvec_type): Use fewer bits.
1919 (PSEUDOVECTOR_SIZE_BITS): New constant.
1920 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1921 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1922 change in pvec_type.
1923 (PSEUDOVECTOR_TYPEP): New macro.

1927 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1928 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1929 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1930 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1931 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1932 abusing vector->header.next.nbytes.
1933 (live_vector_p): Use PVEC_TYPE.
1934 (mark_object): Adapt code to extract pvectype. Use switch.
1936 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1938 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1939 Tighten new eassert a bit.
1941 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1943 Fix compilation with --enable-gcc-warnings and -O1
1945 * doprnt.c (doprnt): Change type of tem to int, initialize
1946 to avoid compiler warning. Add eassert.
1947 * search.c (simple_search): Initialize match_byte to avoid
1948 compiler warning. Add eassert.
1950 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1952 Avoid weird behavior with large horizontal scrolls.
1953 Without this change, for example, large hscroll values would
1954 mess up Emacs's display on Fedora 15 x86, presumably due to
1955 overflows in int calculations in the display code.
1956 Also, if buffers had long lines, Emacs would freeze.
1957 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1958 (set_window_hscroll): New function, containing the old guts of
1959 Fset_window_hscroll. Return the clipped value.
1960 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1961 This avoids the need to check against PTRDIFF_MAX.
1963 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1965 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1967 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1969 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1971 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1972 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1973 since GCC 4.4.6 issues a bogus warning for them.
1975 Fix bugs in file timestamp newness comparisons.
1976 * fileio.c (Ffile_newer_than_file_p):
1977 * lread.c (Fload): Use full timestamp resolution of files,
1978 not just the 1-second resolution, so that files that are only
1979 slightly newer still count as newer.
1980 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1981 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1983 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1985 * fileio.c: Improve handling of file time marker. (Bug#11852)
1986 (special_mtime): New function.
1987 (Finsert_file_contents, Fverify_visited_file_modtime):
1988 Use it to set special mtime values consistently.
1990 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1992 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1993 marker for non-existing file. (Bug#11852)
1995 2012-07-03 Glenn Morris <rgm@gnu.org>
1997 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1998 and did not make it into globals.h).
2000 2012-07-03 Tom Tromey <tromey@redhat.com>

2046 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2047 values which aren't power of 2.
2048 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2049 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2052 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2054 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

2058 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2060 * alloc.c (allocate_vector_block): Remove redundant
2061 calls to mallopt if DOUG_LEA_MALLOC is defined.
2062 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2063 avoid calls to mallopt if zero_vector is returned.
2065 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2067 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2068 is enabled, avoid dereferencing NULL current_sblock if
2071 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2073 Cleanup basic buffer management.
2074 * buffer.h (struct buffer): Change layout to use generic vector
2075 marking code. Fix some comments. Change type of 'clip_changed'
2076 to bitfield. Remove unused #ifndef old.
2077 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2078 (GET_OVERLAYS_AT): Fix indentation.
2079 (for_each_per_buffer_object_at): New macro.

2083 * alloc.c (allocate_buffer): Adjust to match new layout of
2084 struct buffer. Fix comment.
2085 (mark_overlay): New function.

2088 (mark_object): Use it. Adjust marking of misc objects
2089 and related comments.
2091 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2093 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2094 wrapper that is not needed because the wrapped code is a no-op (zero
2095 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2096 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2098 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2100 * alloc.c (mark_buffer): Simplify. Remove prototype.
2101 (mark_object): Add comment. Reorganize marking of vector-like
2102 objects. Use CHECK_LIVE for all vector-like objects except buffers
2103 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2104 redundant calls to mark_vectorlike for bool vectors.
2106 2012-06-30 Glenn Morris <rgm@gnu.org>
2108 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2110 * epaths.in (PATH_SITELOADSEARCH): New.
2111 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2112 This is rather than relying on --enable-locallisppath elements
2113 having "site-lisp" in their names. (Bug#10208#25, 11658)
2115 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2117 * w32proc.c (sys_select): Accept and ignore one more argument.
2119 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2121 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2122 (pselect) [!MS_DOS]: Redirect to sys_select.
2124 * sysdep.c: Don't include dos.h and dosfns.h.
2126 * process.c (sys_select):
2127 * msdos.c (sys_select): Accept one more argument and ignore it.
2129 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2130 adapt data types and code to that.
2133 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2134 which clashes with the gnulib function of the same name.
2136 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2138 * font.c (font_style_to_value, font_style_symbolic)
2139 (font_prop_validate_style): Add type checks for values in
2142 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2144 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2147 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2149 * xdisp.c (try_window_id): Undo last change.
2151 * w32.c (getwd): Adjust commentary about startup_dir.
2152 (init_environment): Always call sys_access, even in non-MSVC
2153 builds. Don't chdir to the directory of the Emacs executable.
2154 This undoes code from 1997 which was justified by the need to
2155 "avoid conflicts when removing and renaming directories". But its
2156 downside was that every relative file name was being interpreted
2157 relative to the directory of the Emacs executable, which can never
2158 be TRT. In particular, it broke sys_access when called with
2159 relative file names.
2160 (sys_access): Map GetLastError to errno.
2162 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2164 * window.h (struct window): Change type of 'fringes_outside_margins'

2168 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2171 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2173 * gnutls.c (emacs_gnutls_handshake):
2174 Add QUIT to make the loop interruptible.
2176 2012-06-29 Glenn Morris <rgm@gnu.org>
2178 * charset.c (init_charset): Make lack of etc/charsets fatal.
2180 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2182 * editfns.c (region_limit): Fix type mismatch.
2184 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

2187 undefined. Convert from xassert to eassert.
2188 * nsmenu.m: Convert from xassert to eassert.
2189 * nsterm.m: Likewise.
2191 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2193 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2195 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2197 Avoid integer overflow on scroll-left and scroll-right.
2198 * window.c (HSCROLL_MAX): New macro.
2199 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2200 overflow when requested scroll falls outside ptrdiff_t range.
2202 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2204 * window.h (struct window): Change type of 'hscroll',
2205 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2206 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2207 Adjust users accordingly.
2208 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2209 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2210 from EMACS_INT to ptrdiff_t.
2211 (make_window): Omit redundant initialization.
2213 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2215 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2217 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2219 * window.h (struct window): Change type of 'use_time' and
2220 'sequence_number' from Lisp_Object to int.

2230 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2231 adjust comments accordingly.

2286 * alloc.c (allocate_string): Omit intervals initialization.
2287 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2288 as in make_pure_string and make_pure_c_string.

2342 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
2344 * alloc.c: Remove build_string.
2345 * lisp.h: Define build_string as static inline. This provides
2346 a better opportunity to optimize away calls to strlen when the
2347 function is called with compile-time constant argument.
2348 * image.c (imagemagick_error): Convert to build_string.
2349 * w32proc.c (sys_spawnve): Likewise.
2350 * xterm.c (x_term_init): Likewise.
2352 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2354 Use sprintf return value instead of invoking strlen on result.
2355 In the old days this wasn't portable, since some sprintf
2356 implementations returned char *. But they died out years ago and
2357 Emacs already assumes sprintf returns int.
2358 Similarly for float_to_string.
2359 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2360 * ccl.c (ccl_driver):
2361 * character.c (string_escape_byte8):
2362 * data.c (Fnumber_to_string):

2364 * print.c (print_object):
2365 * xdisp.c (message_dolog):
2366 * xfns.c (syms_of_xfns):
2367 Use sprintf or float_to_string result to avoid need to call strlen.
2368 * data.c (Fnumber_to_string):
2369 Use make_unibyte_string, since the string must be ASCII.
2370 * lisp.h, print.c (float_to_string): Now returns int length.
2371 * term.c (produce_glyphless_glyph):
2372 Use sprintf result rather than recomputing it.
2374 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2375 * Makefile.in (ALL_CFLAGS):
2376 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
2377 * gmalloc.c, regex.c: Include <config.h> unconditionally.
2379 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2381 * dispextern.h (xstrcasecmp): Define to library function
2382 strcasecmp if available.
2383 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
2385 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
2387 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

2398 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2400 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2401 sprintf already null-terminates its output.
2403 * xfns.c (x_window): Remove redundant cast.
2405 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2407 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2408 `const char *' to `char *' to avoid compiler warning.
2410 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2412 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2413 instead of truncating it to 63 (admittedly a generous limit).
2415 * process.c: Fix spelling and caps in comments.
2417 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2419 * emacs.c (setpgrp): Remove definition, unused.

2431 * systime.h [WINDOWSNT]: Include sys/time.h.
2433 * s/ms-w32.h (struct timespec): Definition moved from
2434 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
2436 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2463 Use _Noreturn rather than NO_RETURN.
2464 No need for separate decl merely because of _Noreturn.
2465 * sound.c (sound_warning, parse_sound):
2466 Remove unnecessary forward decls.
2468 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2470 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2471 * lisp.h (WAIT_READING_MAX): New macro.
2472 * dispnew.c (Fsleep_for, sit_for):
2473 * keyboard.c (kbd_buffer_get_event):
2474 * process.c (Faccept_process_output):
2475 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2476 This improves on the previous patch, which introduced a bug
2477 when time_t is unsigned and as wide as intmax_t.
2478 See <http://bugs.gnu.org/9000#51>.
2480 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2482 * dispnew.c (sit_for, Fsleep_for):
2483 * keyboard.c (kbd_buffer_get_event):

2496 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2497 Privately reported by Herbert J. Skuhra.
2498 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2500 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2501 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2503 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2505 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2506 last argument of make_unibyte_string.
2508 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2509 language ID in the event parameters.
2511 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2512 event.code, not the obscure "character set ID".
2514 2012-06-23 Chong Yidong <cyd@gnu.org>
2516 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2518 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2520 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

2535 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2536 Privately reported by Herbert J. Skuhra.
2537 [__FreeBSD__]: Remove "*/" typo after "#include".
2538 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2539 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2540 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2541 Don't assume EMACS_TIME and struct timeval are the same type.
2543 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2545 Support higher-resolution time stamps (Bug#9000).
2546 The time stamps are only nanosecond-resolution at the C level,
2547 since that's the best that any real-world system supports now.
2548 But they are picosecond-resolution at the Lisp level, as that's
2549 easy, and leaves room for future OS improvements.
2551 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2554 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2555 Don't get current time unless it's needed.
2557 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2558 now provides it if it's absent.
2559 (start_atimer): Port to higher-res time stamps.
2560 Check for time stamp overflow. Don't get current time more
2561 often than is needed.
2563 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2564 Include systime.h, not time.h.
2565 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2567 * dired.c: Include stat-time.h.
2568 (Ffile-attributes): File times now have higher resolution.
2570 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2571 (struct image): Timestamp now has higher resolution.
2573 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2574 has at least microseconds now. All uses removed.
2575 (update_frame, update_single_window, update_window, update_frame_1)
2576 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2578 * editfns.c (time_overflow): Now extern.
2579 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2580 (float-time, Fformat_time_string, Fcurrent_time_string)
2581 (Fcurrent_time_zone): Accept and generate higher-resolution
2583 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2584 (decode_time_components, lisp_seconds_argument): New functions.
2585 (make_time): Now static.
2586 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2587 Report an error if the time is invalid, rather than having the caller
2590 * fileio.c: Include <stat-time.h>
2591 (Fcopy_file): Copy higher-resolution time stamps.
2592 Prefer to set the time stamp via a file descriptor if that works.
2593 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2594 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2595 (Fvisited_file_modtime, Fset_visited_file_modtime):
2596 Support higher-resolution time stamps.
2598 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2600 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2602 * image.c (prepare_image_for_display, clear_image_cache)
2603 (lookup_image): Port to higer-resolution time stamps.
2605 * keyboard.c (start_polling, bind_polling_period):
2606 Check for time stamp overflow.
2607 (read_char, kbd_buffer_get_event, timer_start_idle)
2608 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2609 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2610 Port to higher-resolution time stamps. Do not assume time_t is signed.
2611 (decode_timer): New function. Timers are now vectors of length 9,
2612 not 8, to accommodate the picosecond component.
2613 (timer_check_2): Use it.
2615 * nsterm.m (select_timeout, timeval_subtract): Remove.
2616 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2617 as they're a bit more accurate and handle overflow better.
2618 (ns_select): Change prototype to be compatible with pselect.
2619 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2620 * nsterm.h (ns_select): Adjust prototype.
2622 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2623 us-resolution time stamps.
2624 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2626 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2628 * lisp.h (time_overflow): New decl.
2629 (wait_reading_process_output): First arg is now intmax_t, not int,
2630 to accommodate larger waits.
2632 * process.h (struct Lisp_Process.read_output_delay):
2633 Now counts nanoseconds, not microseconds.
2634 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2636 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2637 (wait_reading_process_output):
2638 Port to ns-resolution time stamps.
2639 (Faccept_process_output, wait_reading_process_output):
2640 Check for time stamp overflow. Do not assume time_t is signed.
2641 (select_wrapper): Remove; we now use pselect.
2642 (Fprocess_attributes): Now generates ns-resolution time stamps.
2644 * sysdep.c: Include utimens.h. Don't include utime.h
2645 or worry about struct utimbuf; gnulib does that for us now.
2646 (gettimeofday): Remove; gnulib provides a substitute.
2647 (make_timeval): New function.
2648 (set_file_times): Now sets ns-resolution time stamps.
2649 New arg FD; all uses changed.
2650 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2651 (system_process_attributes):
2652 Now returns ns-resolution time stamp. All uses changed.
2653 Check for time stamp overflow.
2655 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2656 provides a substitute now.
2658 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2659 since it guarantees struct timespec.
2660 (EMACS_TIME): Now struct timespec, so that we can support
2661 ns-resolution time stamps.
2662 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2663 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2664 (EMACS_USECS): Remove.
2665 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2666 so multiply the arg by 1000 before storing it.
2667 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2669 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2670 Port to ns-resolution time stamps.
2671 (EMACS_TIME_NEG_P): Remove; replaced by....
2672 (EMACS_TIME_SIGN): New macro.
2673 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2674 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2675 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2676 (make_timeval, make_lisp_time, decode_time_components): New decls.
2677 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2678 that it mishandled time_t overflow. You can't compare by subtracting!
2679 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2680 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2682 * term.c: Include <sys/time.h>.
2683 (timeval_to_Time): New function, for proper overflow wraparound.
2684 (term_mouse_position, term_mouse_click): Use it.
2686 * undo.c (record_first_change): Support higher-resolution time stamps
2688 (Fprimitive_undo): Use them when restoring time stamps.
2690 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2691 (w32_get_internal_run_time):
2692 Port to higher-resolution Emacs time stamps.
2693 (ltime): Now accepts single 64-bit integer, as that's more convenient
2696 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2698 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2699 for compatibility with pselect. Support ns-resolution time stamps.
2701 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2703 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2704 Check for time stamp overflow, and support ns-resolution time stamps.
2706 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2707 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2708 (timeval_subtract): Remove; no longer needed.
2709 (XTflash, XTring_bell, x_wait_for_event):
2710 Port to ns-resolution time stamps. Don't assume time_t is signed.
2712 2012-06-22 Chong Yidong <cyd@gnu.org>
2714 * xdisp.c (x_consider_frame_title): Revert last change.
2716 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2718 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2719 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2720 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2721 staticidx goes up to 1597 out of 1600 = 0x640.)
2723 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2725 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2726 Otherwise, the umask might be mistakenly 0 while handling input signals.
2728 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2730 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
2732 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
2734 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
2735 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
2736 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2737 access to `contents' member of Lisp_Vector objects with AREF and ASET
2740 2012-06-19 Chong Yidong <cyd@gnu.org>
2742 * frame.c (delete_frame): When selecting a frame on a different
2743 text terminal, do not alter the terminal's top-frame.
2745 * xdisp.c (format_mode_line_unwind_data): Record the target
2746 frame's selected window and its terminal's top-frame.
2747 (unwind_format_mode_line): Restore them.
2748 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2750 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2751 since tty frames can be explicitly named.
2752 (prepare_menu_bars): Likewise.
2754 * term.c (Ftty_top_frame): New function.
2756 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2758 Port byte-code-meter to modern targets.
2759 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2760 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2761 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2762 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2763 (METER_1, METER_2): Simplify.
2765 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2767 * data.c (Fdefalias): Return `symbol' (bug#11686).
2769 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2771 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2772 gets killed during executing of this function (Bug#11665).
2773 Try to always return Qt when the buffer has been actually killed.
2774 (Vkill_buffer_query_functions): In doc-string say that functions
2775 run by this hook should not change the current buffer.
2777 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2779 Fix recently-introduced process.c problems found by static checking.
2780 * process.c (write_queue_push, write_queue_pop, send_process):
2781 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
2782 (write_queue_pop): Fix pointer signedness problem.
2783 (send_process): Remove unused local.
2785 2012-06-17 Chong Yidong <cyd@gnu.org>
2787 * xdisp.c (redisplay_internal): No need to redisplay terminal
2788 frames that are not on top.
2790 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
2792 * process.c (make_process): Initialize write_queue.
2793 (write_queue_push, write_queue_pop): New functions.
2794 (send_process): Use them to maintain correct ordering of process
2797 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2799 * lisp.h (eassert): Assume C89 or later.
2800 This removes the need for CHECK.
2801 (CHECK): Remove. Its comments about always evaluating its

2995 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2996 Use an inline function on all platforms when using the union type,
2997 since this is simpler and 'static inline' can be used portably

3141 * doprnt.c (doprnt): Truncate multibyte char correctly.
3142 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3143 would mishandle a string argument "Xc" if X was a multibyte

3228 and 'double' in a couple of places.
3230 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3232 * xdisp.c (handle_stop): Detect whether we have overlay strings
3233 loaded by testing it->current.overlay_string_index to be
3234 non-negative, instead of checking whether n_overlay_strings is
3235 positive. (Bug#11587)

3252 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3253 for the duration of call to load_charset, to avoid problems with
3254 callers of maybe_unify_char that access buffer text through C
3257 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3258 decrement the inhibition flag, instead of just setting or

3264 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

3268 (gray_bitmap_bits): Remove; no longer needed.

3281 (safe_bcopy): Remove decl; no longer has that name.
3282 (main): Coalesce #if into single bit of code, for simplicity.
3283 Cast pointers to uintptr_t, since standard libraries want integers
3285 * lisp.h (__executable_start): New decl.
3287 2012-05-31 Glenn Morris <rgm@gnu.org>
3289 * image.c (Fimagemagick_types): Doc fix.

3312 Do not create empty overlays with the evaporate property (Bug#9642).
3313 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3314 Bug#9642, but explicitly check that the buffer the overlay would
3315 be moved to is live and rearrange lines to make sure that errors
3316 will not put the overlay in an inconsistent state.
3317 (Fdelete_overlay): Cosmetics.
3319 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3321 * w32term.c (my_bring_window_to_top): New function.
3322 (x_raise_frame): Use handle returned by DeferWindowPos, which
3323 could be different from the original one.

3327 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3328 by calling BringWindowToTop.
3330 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3331 (WM_EMACS_END): Increase by one.
3333 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3335 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3336 This avoids undefined behavior that might cause the eassert
3337 to not catch an out-of-range value.
3339 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3341 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3342 Update dependencies.
3344 2012-05-27 Eli Zaretskii <eliz@gnu.org>

3350 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3351 when referring to sectname field in printf format.
3353 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3355 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3356 Only r_alloc_inhibit_buffer_relocation needed to be added;
3357 the others were already declared.
3359 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3360 before checking whether it's out of range. Put the check inside
3362 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3364 2012-05-27 Ken Brown <kbrown@cornell.edu>
3366 * callproc.c (Fcall_process): Restore a line that was accidentally
3367 commented out in the 2011-02-13 change (bug#11547).
3369 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3371 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3372 defined on ralloc.c.
3374 * buffer.c [REL_ALLOC]: Remove prototypes of
3375 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3376 they are now on lisp.h.
3378 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3380 * search.c (search_buffer): Use it to inhibit relocation of buffer
3381 text while re_search_2 is doing its job, because re_search_2 is
3382 passed C pointers to buffer text. (Bug#11519)
3384 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3387 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3388 state after an additional call to move_it_in_display_line_to, keep
3389 the values of it->max_ascent and it->max_descent found for the
3391 (pos_visible_p): Revert the comparison against bottom_y to what it
3392 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3395 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3397 Fix coding-related core dumps with gcc -ftrapv.
3398 The code was computing A - B, where A and B are pointers, and B is
3399 random garbage. This can lead to core dumps on platforms that
3400 have special pointer registers, and it also leads to core dumps on
3401 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3402 A - B only when B is initialized properly.
3403 * coding.c (coding_set_source, coding_set_destination): Return void.
3404 (coding_change_source, coding_change_destinations): New functions,
3405 with the old behaviors of coding_set_source and coding_set_destination.
3406 All callers that need an offset changed to use these new functions.
3408 2012-05-26 Glenn Morris <rgm@gnu.org>
3410 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3412 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3414 Extend mouse support on W32 text-mode console.
3415 * xdisp.c (draw_row_with_mouse_face):
3416 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3418 * w32console.c: Include window.h.
3419 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3421 (initialize_w32_display): Initialize mouse-highlight data.
3423 * w32inevt.c: Include termchar.h and window.h.
3424 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3425 moves, call note_mouse_highlight. If help_echo changed, call
3426 gen_help_event to produce help-echo message in the echo area.
3427 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3430 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3432 * lread.c (read1): Simplify slightly to avoid an overflow warning
3433 with GCC 4.7.0 on x86-64.
3435 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3437 * bidi.c (bidi_mirror_char): Revert last change: an int is
3438 definitely wide enough here.
3440 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3442 Fix integer width and related bugs (Bug#9874).

3450 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3452 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3453 (allocate_pseudovector):
3454 Use int, not EMACS_INT, where int is wide enough.
3455 (inhibit_garbage_collection, Fgarbage_collect):
3456 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3457 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3458 int might not be wide enough.
3459 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3463 (bidi_level_of_next_char, bidi_move_to_visually_next):
3464 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3465 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3466 (Fkill_buffer, Fset_buffer_major_mode)

3473 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3474 (Foverlay_recenter, last_overlay_modification_hooks_used)
3475 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3476 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3477 (validate_region): Omit unnecessary test for b <= e,
3478 since that's guaranteed by the previous test.
3479 (adjust_overlays_for_delete): Avoid pos + length overflow.
3480 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3481 (report_overlay_modification):
3482 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3483 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3484 Omit pointer cast, which isn't needed anyway, and doesn't work
3485 after the EMACS_INT -> ptrdiff_t change.
3486 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3487 * buffer.h: Adjust decls to match defn changes elsewhere.

3491 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3492 not int, to avoid needless 32-bit limit on 64-bit hosts.
3493 (exec_byte_code): Use tighter memory-full test, one that checks
3494 for alloca overflow. Don't compute the address of the object just
3495 before an array, as that's not portable. Use EMACS_INT, not
3496 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3497 * callint.c (Fcall_interactively):
3498 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3499 * callproc.c (call_process_kill, Fcall_process):

3509 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3510 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3511 (casify_object): Avoid integer overflow when overallocating buffer.
3512 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3513 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3514 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3515 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3516 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3517 integers are now checked earlier. All uses replaced with XINT.
3519 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3520 For CCL_MapSingle, check that content and value are in int range.
3521 (ccl_driver, Fregister_code_conversion_map):
3522 Check that Vcode_version_map_vector is a vector.
3523 (resolve_symbol_ccl_program): Check that vector header is in range.
3524 Always copy the vector, so that we can check its contents reliably
3525 now rather than having to recheck each instruction as it's being
3526 executed. Check that vector words fit in 'int'.
3527 (ccl_get_compiled_code, Fregister_ccl_program)
3528 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3529 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3530 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3531 contents are in range.
3532 (Fccl_execute_on_string): Check that status is in range.
3533 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3534 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3535 Accept and return EMACS_INT, not int, because callers can pass values
3537 (c_string_width, strwidth, lisp_string_width, chars_in_text)

3541 (string_escape_byte8, Fget_byte):
3542 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3543 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3544 avoid mishandling large integers.
3545 * character.h: Adjust decls to match defn changes elsewhere.

3554 (Fdefine_charset_internal): Check ranges here, more carefully.
3555 Don't rely on undefined behavior with signed left shift overflow.
3556 Don't assume unsigned int fits into fixnum, or that fixnum fits
3557 into unsigned int. Don't require max_code to be a valid fixnum;
3558 that's not true for gb10830 4-byte on a 32-bit host. Allow
3559 invalid_code to be a cons, for the same reason. Require code_offset
3560 to be a character. Avoid int overflow if max_char is close
3562 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3563 this is intended anyway and avoids some undefined behavior.
3564 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3565 INDEX_TO_CODE_POINT, as that's what it expects.
3566 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3567 * charset.h (DECODE_CHAR): Return int, not unsigned;
3568 this is what was intended anyway, and it avoids undefined behavior.
3569 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3570 integer-overflow issues.
3571 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3572 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3573 where the argument is EMACS_INT, and this behavior is not intended.
3574 * chartab.c (Fmake_char_table, Fset_char_table_range)
3575 (uniprop_get_decoder, uniprop_get_encoder):
3576 Don't assume fixnum fits in int.
3577 * cmds.c (move_point): New function, that does the gist of
3578 Fforward_char and Fbackward_char, but does so while checking
3579 for integer overflow more accurately.
3580 (Fforward_char, Fbackward_char): Use it.
3581 (Fforward_line, Fend_of_line, internal_self_insert)
3582 (internal_self_insert):
3583 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3584 Fix a FIXME, by checking for integer overflow when calculating
3585 target_clm and actual_clm.

3620 Don't access memory outside of the args array.
3621 (Fdefine_coding_system_internal): Check for charset-id overflow.

3642 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
3643 Do not attempt to compute the address of the object just before a

3647 (Faset): Use int, not EMACS_INT, where int is wide enough.
3648 (Fstring_to_number): Don't assume fixnums fit in int.

4402 and right-margin display specs even if the spec is invalid or we
4403 are on a TTY, and thus unable to display on the fringes.
4404 That's because the text with the property will not be displayed anyway,
4405 so we need to signal to the caller that this is a "replacing"
4406 display spec. This fixes display when the spec is invalid or we

4411 * unexaix.c (make_hdr): Fix typo in prototype.
4412 This bug broke the build on AIX. Problem reported by Gilles Pion.
4414 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4416 * keyboard.c (kbd_buffer_get_event): Read special events also in
4417 batch mode. (Bug#11415)
4419 2012-05-12 Glenn Morris <rgm@gnu.org>
4421 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4423 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4425 * lisp.mk (lisp): Add newcomment.elc.
4427 2012-05-12 Glenn Morris <rgm@gnu.org>
4429 * Makefile.in (MKDIR_P): New, set by configure.
4430 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4432 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4434 Remove unused function hourglass_started.
4435 * dispextern.h (hourglass_started):
4436 * w32fns.c (hourglass_started):
4437 * xdisp.c (hourglass_started): Remove.
4439 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4441 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4442 Update dependencies.
4444 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4446 * xgselect.c (xg_select): Put maxfds+1 into a var.
4447 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4449 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4451 2012-05-10 Dave Abrahams <dave@boostpro.com>
4453 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4454 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4456 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4458 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4459 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4460 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4461 Initialize xd_registered_buses.
4463 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4465 Untag more efficiently if USE_LSB_TAG.
4466 This is based on a proposal by YAMAMOTO Mitsuharu in
4467 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4468 For an admittedly artificial (nth 8000 longlist) benchmark on
4469 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4470 Emacs's overall text size by 1%.
4471 * lisp.h (XUNTAG): New macro.
4472 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4473 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4474 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4475 * eval.c (Fautoload):
4476 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4477 * frame.h (XFRAME): Use XUNTAG.
4479 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4480 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4481 Remove unportable assumptions about print widths of types like
4483 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4484 intptr_t when converting between pointer and integer, to avoid GCC
4485 warnings about wrong width.
4487 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4489 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4490 stack for each reader_thread, instead of defaulting to 8MB
4491 determined by the linker. This avoids failures in creating
4492 subprocesses on Windows 7, see the discussion in this thread:
4493 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4495 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4497 Fix up display of the *Minibuf-0* buffer in the mini window.
4498 * keyboard.c (read_char): Don't clear the echo area if there's no
4500 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4501 contents of *Minibuf-0*) if there's no message displayed in its stead.
4503 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4505 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4508 2012-05-06 Chong Yidong <cyd@gnu.org>
4510 * lisp.mk (lisp): Update.
4512 2012-05-05 Jim Meyering <meyering@redhat.com>
4514 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4516 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4518 * data.c (PUT_ERROR): New macro.
4519 (syms_of_data): Use it. Add new error type `user-error'.
4520 * undo.c (user_error): New function.
4521 (Fprimitive_undo): Use it.
4522 * print.c (print_error_message): Adjust print style for `user-error'.
4523 * keyboard.c (user_error): New function.
4524 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4526 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4528 Do not limit current-time-string to years 1000..9999.
4529 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4530 (Fcurrent_time_string): Support any year that is supported by the
4531 underlying localtime representation. Don't use asctime, as it
4532 has undefined behavior for years outside the range -999..9999.
4534 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4536 Fix race conditions involving setenv, gmtime, localtime, asctime.
4537 Without this fix, interrupts could mess up code that uses these
4538 nonreentrant functions, since setting TZ invalidates existing
4539 tm_zone or tzname values, and since most of these functions return
4540 pointers to static storage.
4541 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4542 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4543 Grow the critical sections to include not just invoking
4544 localtime/gmtime, but also accessing these functions' results
4545 including their tm_zone values if any, and any related TZ setting.
4546 (format_time_string): Last arg is now struct tm *, not struct tm **,
4547 so that the struct tm is saved in the critical section.
4548 All callers changed. Simplify allocation of initial buffer, partly
4549 motivated by the fact that memory allocation needs to be outside
4550 the critical section.
4552 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4554 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4555 with RESET_INTERVAL.
4557 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4558 Remove duplicated buffer name initialization.
4560 2012-05-02 Jim Meyering <jim@meyering.net>
4562 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4564 * xfns.c (x_window): Use xstrdup (Bug#11375).
4566 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4568 * xdisp.c (pos_visible_p): If already at a newline from the
4569 display string before the 'while' loop, don't walk back the glyphs
4570 from it3.glyph_row. Solves assertion violation when the display
4571 string begins with a newline (egg.el). (Bug#11367)
4573 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4575 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4578 2012-05-01 Glenn Morris <rgm@gnu.org>
4580 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4581 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4582 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4583 All were removed before 23.1.
4585 * dispnew.c: Remove HAVE_LIBNCURSES test;
4586 it is always true on relevant platforms.
4588 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4589 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4591 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4593 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4595 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4596 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4599 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4601 Do not avoid creating empty evaporating overlays (Bug#9642).
4602 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4603 That is, do not delete an evaporating overlay if it becomes
4604 empty after its bounds are adjusted to fit within its buffer.
4605 This fix caused other problems, and I'm reverting it until we get
4606 to the bottom of them.
4608 2012-04-27 Chong Yidong <cyd@gnu.org>
4610 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4612 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4614 * xdisp.c (pos_visible_p): If the window start position is beyond
4615 ZV, start the display from buffer beginning. Prevents assertion
4616 violation in init_iterator when the minibuffer window is scrolled
4619 * window.c (window_scroll_pixel_based): Likewise.
4621 2012-04-27 Chong Yidong <cyd@gnu.org>
4623 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4625 2012-04-27 Glenn Morris <rgm@gnu.org>
4627 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4628 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4630 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4632 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4633 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4635 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4637 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4638 display element, check also the underlying string or buffer
4639 character. (Bug#11341)
4641 * w32menu.c: Include w32heap.h.
4642 (add_menu_item): If the call to AppendMenuW (via
4643 unicode_append_menu) fails, disable Unicode menus only if we are
4644 running on Windows 9X/Me.
4646 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4648 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4649 (xgetint): Add missing shift for LSB tags.
4651 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4653 * keyboard.c (read_char): Don't wipe echo area for select window
4654 events: These might get delayed via `mouse-autoselect-window'
4657 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4659 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4660 manipulation of :loaded-from data.
4662 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4664 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4665 now a cons (bug#11311).
4667 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4669 Do not create empty overlays with the evaporate property (Bug#9642).
4670 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4671 if it becomes empty after its bounds are adjusted to fit within
4672 its buffer. Without this fix, in a nonempty buffer (let ((o
4673 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4674 yields an empty overlay that has the evaporate property, which is
4675 not supposed to happen.
4677 Fix minor GTK3 problems found by static checking.
4678 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4679 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4680 (struct _EmacsFixedClass, emacs_fixed_get_type):

4688 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4689 (EMACS_FIXED_GET_CLASS): Remove; unused.
4690 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4692 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4693 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4695 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4697 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4698 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4699 (__malloc_size_t, __malloc_ptrdiff_t):
4700 Remove. All uses removed, replaced by the definiens if needed,
4701 since we can assume C89 or better now.
4702 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4703 (protect_malloc_state, align, get_contiguous_space)
4704 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
4705 (malloc_atfork_handler_child, malloc_enable_thread)

4710 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4711 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4712 Define using prototypes, not old style.
4713 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4714 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4715 (align): Don't assume that signed integer overflow wraps around.
4716 Omit unused local var.
4717 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4718 (_free_internal_nolock, memalign, mallochook, reallochook):
4719 Omit no-longer-needed casts.
4720 (valloc): Use getpagesize, not __getpagesize.

4722 (struct hdr): The 'magic' member is now size_t, not unsigned long.
4724 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4726 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

4774 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
4775 Do not assume ptrdiff_t is the same width as 'int'.
4777 * alloc.c: Handle unusual debugging option combinations.
4778 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4779 since the two debugging options are incompatible.
4780 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

4792 * sysdep.c [__FreeBSD__]: Minor cleanups.
4793 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4794 Use Emacs indenting style more consistently. Avoid some casts.
4795 Use 'double' consistently rather than mixing 'float' and 'double'.
4797 2012-04-21 Eduard Wiebe <usenet@pusto.de>
4799 * sysdep.c (list_system_processes, system_process_attributes):

4834 row, return zero immediately.
4835 (try_cursor_movement): If inside continuation line, don't back up
4836 farther than the first row after the header line, if any.
4837 Don't consider the header-line row as "partially visible", even if
4838 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4840 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4875 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
4876 New extern decls, to avoid calling undeclared functions.
4877 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4878 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4879 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4880 (NEED_MEM_INSERT): New macro.
4881 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4882 Remove one incorrect comment and fix another.

4888 (r_alloc_sbrk): Now static.
4890 Improve ralloc.c interface checking.
4891 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

4896 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4897 Remove decls. This fixes an "It stinks!".

4901 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4903 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4916 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4917 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4918 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4919 * s/netbsd.h, s/sol2-6.h:
4920 Remove definition of GC_MARK_STACK, since the default now works.
4921 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4922 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4923 no longer the default.
4924 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4926 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4928 * lread.c (lisp_file_lexically_bound_p):

4949 2012-04-11 Daniel Colascione <dancol@dancol.org>
4951 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4952 against is gone. It's better to use vfork now so that when Cygwin
4953 gains a new, working vfork, we use it automatically (bug#10398).
4955 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4973 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
4975 * w32.c (w32_delayed_load): Record the full path of the library
4976 being loaded (bug#10424).
4978 2012-04-09 Glenn Morris <rgm@gnu.org>
4980 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4981 not just in the obarray, before snarfing them. (Bug#11036)
4983 * Makefile.in ($(leimdir)/leim-list.el):
4984 Pass EMACS rather than BUILT_EMACS.

5008 * minibuf.c (Fread_variable): Callers changed.
5010 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5012 * xdisp.c (set_cursor_from_row): If the display string appears in
5013 the buffer at position that is closer to point than the position
5014 after the display string, display the cursor on the first glyph of
5015 the display string. Fixes cursor display when a 'display' text
5016 property immediately follows invisible text. (Bug#11094)
5018 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5020 composite.c: use 'double' consistently
5021 * composite.c (get_composition_id): Use 'double' consistently
5022 instead of converting 'float' to 'double' and vice versa; this is
5023 easier to understand and avoids a GCC warning.
5025 2012-04-09 Glenn Morris <rgm@gnu.org>
5027 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5028 preparation for dumping it with emacs. (Bug#4789)

5050 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5051 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5052 objects, as mark_maybe_pointer will catch them otherwise.
5053 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5054 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5056 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5058 Fix typo that broke non-Windows builds.
5059 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5069 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5070 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5071 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5072 [!WINDOWSNT]: New macros.
5073 (init_libxml2_functions, libxml2_loaded_p): New functions.
5074 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5075 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5076 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5077 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5079 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5080 Call init_libxml2_functions before calling libxml2 functions.
5081 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5083 * emacs.c: Don't include libxml/parser.h.
5084 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5085 xmlCleanupParser directly.
5087 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5089 2012-04-07 Eli Zaretskii <eliz@gnu.org>

5097 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5098 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5099 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5100 macros related to unification of CJK characters. For the details,
5101 see the discussion following the message here:
5102 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5104 2012-04-04 Chong Yidong <cyd@gnu.org>
5106 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5108 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5110 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5118 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5120 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5121 position we get to after a call to move_it_to fails the
5122 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5123 only if we wind up in a string from display property. (Bug#11063)
5125 * window.c (Fdelete_other_windows_internal): Invalidate the row
5126 and column information about mouse highlight, so that redisplay
5127 restores it after reallocating the glyph matrices. (Bug#7464)
5129 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5130 string comes from a `display' text property, use the buffer
5131 position of that property as if we actually saw that position in
5133 (move_it_by_lines): Remove the assertion that
5134 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5135 violated when there's a before-string at the beginning of a line.
5138 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5140 * xdisp.c (append_space_for_newline): If the default face was
5141 remapped, use the remapped face for the appended newline.
5142 (extend_face_to_end_of_line): Use the remapped default face for
5143 extending the face to the end of the line.
5144 (display_line): Call extend_face_to_end_of_line when the default
5145 face was remapped. (Bug#11068)
5147 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5149 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5173 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5175 2012-03-25 Kenichi Handa <handa@m17n.org>
5177 * dispextern.h (struct glyph): Change the bit length of
5178 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5180 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5182 * s/ms-w32.h (tzname): Include time.h before redirecting to
5183 _tzname. Fixes the MSVC build. (Bug#9960)
5185 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5187 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5190 * xterm.c (XTread_socket): Only modify handling_signal if
5191 !SYNC_INPUT. (Bug#11080)
5193 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5195 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5196 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5197 when fetching a multibyte character consumes more bytes than
5198 CHAR_BYTES returns, due to unification of CJK characters in
5199 string_char. (Bug#11073)
5201 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5203 * process.c (wait_reading_process_output): Handle pty disconnect

5238 that is not from display property, accept the row as a "cursor
5239 row" if one of the string's character has a non-nil `cursor'
5240 property. Fixes cursor positioning when there are newlines in
5241 overlay strings, e.g. in icomplete.el. (Bug#11035)
5243 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

5249 * eval.c (inhibit_lisp_code): Rename from
5250 inhibit_window_configuration_change_hook; move from window.c.
5252 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5253 * window.c (run_window_configuration_change_hook)
5254 (syms_of_window): Callers changed.
5256 2012-03-11 Chong Yidong <cyd@gnu.org>

5269 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5271 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5273 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5274 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5277 2012-03-03 Glenn Morris <rgm@gnu.org>
5279 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5281 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5283 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5284 position past the first glyph_row that ends at ZV. (Bug#10902)
5285 (redisplay_window, next_element_from_string): Fix typos in
5287 (redisplay_window): Pass to move_it_vertically the margin in
5288 pixels, not in screen lines.
5290 2012-03-02 Glenn Morris <rgm@gnu.org>
5292 * buffer.c (buffer-list-update-hook): Doc fix.
5294 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5296 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5297 push_it before setting up the iterator for the first overlay
5298 string, even if we have an empty string loaded.
5299 (next_overlay_string): If there's an empty string on the iterator
5300 stack, pop the stack. (Bug#10903)
5302 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5304 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5305 Suggested by Stefan Monnier in
5306 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5307 * alloc.c (widen_to_Lisp_Object): New static function.
5308 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5309 and widening them to Lisp_Objects. This would work even if
5310 USE_LSB_TAG is defined and wide integers are used, which might
5311 happen in a future version of Emacs.
5313 2012-02-25 Chong Yidong <cyd@gnu.org>
5315 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5318 * xselect.c (Fx_selection_exists_p): Doc fix.
5319 (x_clipboard_manager_save_all): Print an informative message
5320 before saving to clipboard manager.
5322 2012-02-24 Chong Yidong <cyd@gnu.org>

5351 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5352 when computing $valmask.
5354 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5355 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5356 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5357 It's useless in that case, and it can cause problems on hosts
5358 that allocate halves of EMACS_INT values separately.
5359 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5360 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5361 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5362 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5363 it avoids undefined behavior on hosts where shifting right by more
5364 than the word width has undefined behavior.

5490 * character.c (char_width): Return EMACS_INT, not int.
5491 (char_width, c_string_width): Check for overflow when
5492 computing the width; this is possible now that individual
5493 characters can have unbounded width. Problem introduced

6152 to 4 (xorl, subq, cmpq, setbe).
6153 * alloc.c (pure): Always extern now, since that's the
6154 VIRT_ADDR_VARIES behavior.
6155 (PURE_POINTER_P): Use a single comparison, not two, for
6156 consistency with the new puresize.h.

6166 behave as if the cursor position were at the window margin.
6168 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6169 and the cursor position is out of bounds, behave as if the cursor
6170 position were at the window margin. (Bug#10075)

6200 * dispnew.c (verify_row_hash): Call row_hash for computing the
6201 hash code of a row, instead of duplicating code from xdisp.c.
6203 * dispextern.h (row_hash): Add prototype.
6205 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6207 * frame.c (delete_frame): Don't delete the terminal when the last

6239 * image.c (imagemagick_load_image): Fix typo.
6241 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6243 * xdisp.c (display_line): Move the call to
6244 highlight_trailing_whitespace before the call to

6345 of temacs in GUI mode.
6347 2011-11-07 Martin Rudalics <rudalics@gmx.at>
6349 * window.h: Declare delete_all_child_windows instead of

6362 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6363 This is also needed for porting to any host where GC_MARK_STACK is
6364 not GC_MAKE_GCPROS_NOOPS.
6365 (which_symbols): Use it.
6367 2011-11-07 Kenichi Handa <handa@m17n.org>

6380 * xmenu.c (cleanup_widget_value_tree): New function.
6381 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6384 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6386 Fix some portability problems with 'inline'.
6387 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6388 (window_box_width, window_box_left, window_box_left_offset)
6389 (window_box_right, window_box_right_offset): Declare extern.
6390 Otherwise, these inline functions do not conform to C99 and
6391 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6392 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6393 * intervals.c (adjust_intervals_for_insertion)
6394 (adjust_intervals_for_deletion): Now extern, because otherwise the
6395 extern inline functions 'offset_intervals' couldn't refer to it.
6396 (static_offset_intervals): Remove.
6397 (offset_intervals): Rewrite using the old contents of
6398 static_offset_intervals. The old version didn't conform to C99
6399 because an extern inline function contained a reference to an
6400 identifier with static linkage.
6402 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6404 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6422 (Fwindow_vscroll): Doc fix.
6423 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6424 argument, since it makes no sense to pass a live window and for
6425 consistency with window-child.

6453 (unwind_create_frame): New function (Bug#9943).
6454 (Fx_create_frame): Restructure code to be more similar to the one in
6455 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6456 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6457 Move terminal->reference_count++ just before making the frame official

6569 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6571 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6572 so that this new function doesn't get optimized away by a
6573 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6575 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6577 * frame.h (MOUSE_HL_INFO): Remove excess parens.

6600 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6602 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

6604 condition to clear the mouse face.
6606 2011-10-28 Chong Yidong <cyd@gnu.org>

6633 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6635 (w32font_open_internal, compute_metrics):
6636 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6637 instead of calling the "wide" APIs directly.
6639 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6641 * w32.h (syms_of_w32font): Add prototype.
6643 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6652 * process.c (make_process): Set gnutls_state to NULL.
6654 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6655 non-NULL, regardless of GNUTLS_INITSTAGE.
6656 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6657 an error. Set process slots as soon as we allocate them.

6703 current character, check also for next_en_type being WEAK_EN.
6704 (bidi_resolve_weak): Don't enter the expensive loop if the current
6705 position is before next_en_pos. Record the bidi type of the first
6706 non-ET, non-BN character we find, in addition to its position.
6707 (bidi_level_of_next_char): Invalidate next_en_type when
6708 next_en_pos is over-stepped.
6710 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6712 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6713 * editfns.c: Rewrite current-time-zone so that it invokes
6714 the equivalent of (format-time-string "%Z") to get the time zone name.
6715 This fixes a bug when the time zone name contains characters that
6716 need converting from the system time locale to Emacs internal format.
6717 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6718 that patch fixed format-time-string to do the conversion, but
6719 I forgot to fix current-time-zone.
6720 (format_time_string): New function, containing most of
6721 what Fformat_time_string used to contain.
6722 (Fformat_time_string): Rewrite in terms of format_time_string.
6723 This doesn't change this function's behavior.
6724 (current-time-zone): Rewrite to use format_time_string.
6725 This fixes the bug reported by Michael Schierl in
6726 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6727 Jason Rumney's 2007-06-07 change worked around this bug, but
6729 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6731 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6733 * xdisp.c (start_display): If the character at POS is displayed
6734 via a display vector, reset IT->current.dpvec_index to zero.
6735 (try_window_reusing_current_matrix): If a line ends in a display
6736 vector or the next line starts in a display vector, continue
6737 redrawing the window even though the character position of
6738 start_row was reached.
6741 2011-10-18 Chong Yidong <cyd@gnu.org>
6743 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6744 with nobreak-char-display too.
6746 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6748 Fix part 3 of bug#9771.
6749 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6750 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6751 non-neutral characters if the current character is a paragraph
6752 separator (a.k.a. Newline). This avoids running the same
6753 expensive loop twice, once when we consume the preceding newline
6754 and the other time when the line actually needs to be displayed.
6755 Avoid the loop when we see neutrals on the base embedding level
6756 following a character whose directionality is the same as the
6757 paragraph's. This avoids running the expensive loop when a line
6758 ends in a long sequence of neutrals, like control characters.
6759 Add assertion against STRONG_AL type. Slightly rearrange code
6760 that determines the type of a neutral given the first non-neutral
6762 (bidi_level_of_next_char): Set next_en_pos to zero when
6763 invalidating its info.
6765 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6767 * xdisp.c (push_display_prop): Determine whether to record string
6768 or buffer position by IT->string, not by IT->method. Allow
6769 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6770 (move_it_vertically_backward): Don't look for character position
6771 immediately after the newline when in a continuation line.
6774 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6776 * window.c (coordinates_in_window): Rewrite and delabelize
6777 vertical border check. (Bug#5357) (Bug#9618)
6779 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6781 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6782 errors in XSetWindowBorder (bug#9310).
6784 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6786 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6787 avoid crash when xmalloc overrun checking is enabled.
6789 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6791 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6792 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6793 cursor motion with <left> and <right> arrow keys.
6795 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6796 some callers set that themselves.
6798 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6800 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6801 display string and the previous row comes from the same string and
6802 is empty. (Bug#9739) (Bug#9738)
6804 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6806 * doc.c (get_doc_string): Encode file name (bug#9735).
6808 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6810 * bidi.c (bidi_level_of_next_char):
6811 * xdisp.c (get_visually_first_element): Remove old incorrect
6812 comments regarding the Unicode Line Separator character.
6814 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6816 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6818 * alloc.c (Fgc_status): Do not access beyond zombies array
6819 boundary if nzombies > MAX_ZOMBIES.
6820 * alloc.c (dump_zombies): Add missing format specifier.
6822 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6824 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6825 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6827 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6828 Some packages use them to denote characters with modifiers.
6830 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6832 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6833 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6834 matching a pp-number. Rename parameter var to var1.
6836 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6838 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6840 2011-10-08 Glenn Morris <rgm@gnu.org>
6842 * callint.c (Fcall_interactively): Give a more explicit error for the
6843 'c' case with a non-character input. (Bug#8479)
6845 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6847 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6849 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6850 lines that are hscrolled on the left.
6852 * dispnew.c (buffer_posn_from_coords): Account for a possible
6853 presence of header-line. (Bug#4426)
6855 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6857 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6858 Don't advertise functionality which we discourage or doesn't work.
6860 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6862 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6863 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6864 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6865 this makes Emacs dump core during garbage collection on rare
6866 occasions. sizeof is obviously inferior to offsetof here, so
6867 stick with offsetof.
6868 (GC_POINTER_ALIGNMENT): New macro.
6869 (mark_memory): Omit 3rd (offset) arg; caller changed.
6870 Don't assume EMACS_INT alignment is the same as pointer alignment.
6872 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6874 * keyboard.c (read_key_sequence_remapped): New var.
6875 (read_key_sequence): Compute remapping in the right buffer.
6876 (command_loop_1): Use read_key_sequence's remapping directly.
6878 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6880 * dired.c (file_name_completion): Don't expand file name.
6881 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6882 before checking file name handler.
6884 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6885 they've been requested explicitly (bug#9591).
6887 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6889 * keymap.c (Fsingle_key_description): Use make_specified_string
6890 instead of build_string to build string from push_key_description.
6893 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6895 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6896 This fixes a Y2038 bug on 64-bit hosts.
6897 * buffer.c (reset_buffer):
6898 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6899 (Fclear_buffer_auto_save_failure):
6900 Use 0, not -1, to represent an unset failure time, since time_t
6901 might not be signed.
6903 Remove dependency on glibc malloc internals.
6904 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6905 Move back here from lisp.h, but with their new implementations.
6906 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6907 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6908 * charset.c (charset_table_init): New static var.
6909 (syms_of_charset): Use it instead of xmalloc. This removes a
6910 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6911 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6912 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6913 Move back to alloc.c.
6914 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6915 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6917 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6919 * nsterm.m (windowDidResize): Call x_set_window_size only when
6920 ns_in_resize is true. Otherwise set pixelwidth/height and
6921 call change_frame_size (Bug#9628).
6923 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6925 Port --enable-checking=all to Fedora 14 x86-64.
6926 * charset.c (syms_of_charset): Also account for glibc malloc's
6927 internal overhead when calculating the initial malloc maximum.
6929 Port --enable-checking=all to Fedora 14 x86.
6930 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6932 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6933 (overrun_check_realloc, overrun_check_free):
6934 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6935 That way, xmalloc returns a properly-aligned pointer even if
6936 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6937 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6938 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6939 into account when calculating the initial malloc maximum.
6940 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6941 Move here from alloc.c, so that charset.c can use it too.
6942 Properly align; the old code wasn't right for common 32-bit hosts
6943 when configured with --enable-checking=all.
6944 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6945 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6947 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6949 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6952 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6954 * xdisp.c (compute_display_string_end): If there's no display
6955 string at CHARPOS, return -1.
6957 * bidi.c (bidi_fetch_char): When compute_display_string_end
6958 returns a negative value, treat the character as a normal
6959 character not covered by a display string. (Bug#9624)
6961 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6963 * lread.c (Fread_from_string): Fix typo in docstring.
6965 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6967 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6968 newline, reseat the iterator instead of bidi-iterating there one
6969 character at a time. (Bug#9610)
6970 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6971 TO_CHARPOS if the bidi iterator is at base embedding level.
6973 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6975 * lread.c (readevalloop): Use correct code for NBSP.
6976 (read1): Likewise. (Bug#9608)
6978 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6980 * dbusbind.c (Fdbus_register_signal): When service is not
6981 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6983 2011-09-25 Glenn Morris <rgm@gnu.org>
6985 * buffer.c (truncate-lines): Doc fix.
6987 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6989 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6990 (Fset_window_next_buffers): Doc fix.
6992 2011-09-24 Glenn Morris <rgm@gnu.org>
6994 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6996 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6998 Fix minor problems found by static checking.
6999 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7000 * indent.c (Fvertical_motion): Fix == vs = typo.
7002 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7004 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7005 Default value is now t. Doc fix.
7007 * indent.c (Fvertical_motion): Compute and apply the overshoot
7008 logic when moving up, not only when moving down. Fix the
7009 confusing name and values of the it_overshoot_expected variable;
7010 logic changes accordingly. (Bug#9254) (Bug#9549)
7012 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7013 CHARPOS is covered by a display string which includes newlines.
7014 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7015 is covered by a display string with embedded newlines.
7017 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7019 * dbusbind.c (Fdbus_register_signal): Add match rule to
7020 Vdbus_registered_objects_table. (Bug#9581)
7021 (Fdbus_register_method, Vdbus_registered_objects_table):
7024 2011-09-24 Jim Meyering <meyering@redhat.com>
7026 do not ignore write error for any output size
7027 The previous change was incomplete.
7028 While it makes emacs --batch detect the vast majority of stdout
7029 write failures, errors were still ignored whenever the output size is
7030 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7031 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7032 && echo FAIL: ignored write error
7033 FAIL: ignored write error
7034 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7035 && echo FAIL: ignored write error
7036 FAIL: ignored write error
7037 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7039 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7041 * emacs.c (Fkill_emacs): In noninteractive mode exit
7042 non-successfully if a write error occurred on stdout. (Bug#9574)
7044 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7046 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7049 * dispextern.h (struct it): Update the comment documenting what
7052 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7054 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7055 a display string, extend search for cursor position to end of row.
7056 (find_row_edges): If the row ends in a newline from a display
7057 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7058 Handle the case of a display string with multiple newlines.
7059 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7060 non-empty line. Fixes confusing cursor motion with arrow keys at
7061 the beginning of a line that starts with whitespace.
7063 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7065 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7068 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7070 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7073 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7075 * xdisp.c (display_line): Record maximum and minimum buffer
7076 positions even if no glyphs were produced (e.g., by a zero-width
7077 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7078 buffer positions that will be removed from the glyph row because
7080 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7081 column is beyond frame width: don't subtract 1 "pixel" when
7082 computing width of the stretch.
7083 (reseat_at_next_visible_line_start): Undo the change made on
7084 2011-09-17 that saved paragraph information and restored it after
7085 the call to `reseat'. (Bug#9545)
7087 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7089 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7090 and turn window cursor on if cleared (Bug#9415).
7092 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7094 * search.c (boyer_moore): Take unibyte characters from pattern
7095 literally. (Bug#9458)
7097 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7099 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7101 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7103 Fix minor problem found by static checking.
7104 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7105 initialized, to pacify gcc -Wuninitialized.
7107 * fileio.c: Report proper errno when syscall falls.
7108 (Finsert_file_contents): Save and restore errno,
7109 so that report_file_error outputs the correct diagnostic.
7110 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7112 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7114 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7116 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7118 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7119 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7121 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7123 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7124 about the current paragraph and restore it after the call to reseat.
7126 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7127 (bidi_find_paragraph_start): Search back for paragraph beginning
7128 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7129 (bidi_move_to_visually_next): Only trigger paragraph-related
7130 computations when the last character is a newline or at EOB, not
7131 just any NEUTRAL_B. (Bug#9470)
7133 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7134 truncated lines if point is covered by a display string. (Bug#9524)
7136 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7138 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7139 (cons_to_x_long): New function.
7140 (lisp_data_to_selection_data): Use it. Correct the test for
7141 short-versus-long data; it was negated. Break out of vector
7142 loop, for efficiency, when a long datum is discovered.
7144 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7146 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7148 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7150 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7151 GCC PR/17406) by declaring this function with external scope.
7153 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7155 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7156 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7158 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7160 * editfns.c (Fformat): Correctly handle text properties on "%%".
7162 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7164 * xterm.c (x_draw_composite_glyph_string_foreground):
7165 * w32term.c (x_draw_composite_glyph_string_foreground):

7167 * composite.c (composition_update_it, get_composition_id):
7168 * xdisp.c (get_next_display_element)
7169 (fill_composite_glyph_string): Add comments about special meaning
7170 of TAB characters in a composition.
7172 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7174 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7175 This occurs when processing a multibyte format.
7176 Problem reported by Wolfgang Jenker.
7178 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7180 * xdisp.c (try_cursor_movement): Only check for exact match if
7181 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7183 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7185 Remove unused external symbols.
7186 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7187 * xdisp.c (calc_pixel_width_or_height): Now static.
7188 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7189 * indent.c (check_display_width):
7190 * w32term.c: Fix comment to match code.
7191 * xterm.c, xterm.h (x_catching_errors): Remove.
7193 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7195 * xselect.c: Use signed conversions more consistently (Bug#9498).
7196 (selection_data_to_lisp_data): Assume incoming selection data are
7197 signed integers, not unsigned. This is to be consistent with
7198 outgoing selection data, which was modified to use signed integers
7199 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7200 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7201 expects long, not unsigned long.
7203 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7205 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7206 computation of loop end. Reported by Johan Bockgård
7209 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7211 * frame.c (Fother_visible_frames_p): Function deleted.
7213 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7215 * indent.c (compute_motion): Process display vector front to back
7216 rather than the other way around. (Bug#2496)
7218 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7220 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7222 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7224 * minibuf.c (Fread_from_minibuffer): Doc fix.
7226 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7228 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7229 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7231 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7233 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7234 value for non-existent files.
7236 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7238 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7239 set its "size" to -1. This will set the modtime_size field of
7240 the corresponding buffer to -1, which is what
7241 verify-visited-file-modtime expects for files that do not exist.
7244 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7246 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7248 * lisp.h: ... from here. push_key_description is no longer
7249 defined in keyboard.c, so its declaration should not be in
7250 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7251 logically belongs with push_key_description.
7253 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7255 * buffer.h: Include <sys/types.h> instead of <time.h>.
7256 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7257 Problem reported by Herbert J. Skuhra.
7259 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7261 * xml.c (parse_region): Make the parsing work for
7262 non-comment-starting XML files again (bug#9144).
7264 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7266 * image.c (gif_load): Fix calculation of bottom and right corner.
7269 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7271 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7272 redisplay in small windows.
7274 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7276 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7278 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7280 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7281 Operate on live windows only.
7283 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7285 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7287 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7289 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7290 only under bidi iteration.
7292 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7294 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7296 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7298 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7299 Without this fix, the command to link temacs failed due to an
7300 undefined symbol __builtin_isnan. This is because
7301 /usr/include/iso/math_c99.h #defines isnan(x) to
7302 __builtin_isnan(x), but the bundled gcc, which identifies itself
7303 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7305 * floatfns.c (isnan): #undef, and then #define to a clone of
7307 (Fisnan): Always define, since it's always available now.
7308 (syms_of_floatfns): Always define isnan at the Lisp level.
7310 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7312 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7314 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7316 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7317 The previous code assumed that file offsets (off_t values) fit in
7318 EMACS_INT variables, which is not true on typical 32-bit hosts.
7319 The code messed up by falsely reporting buffer overflow in cases
7320 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7321 when "big" contains more than 2**29 bytes, even though this
7322 inserts just one byte and does not overflow the buffer.
7323 (Finsert_file_contents): Store file offsets as off_t
7324 values, not as EMACS_INT values. Check for overflow when
7325 converting between EMACS_INT and off_t. When checking for
7326 buffer overflow or for overlap, take the offsets into account.
7327 Don't use EMACS_INT for small values where int suffices.
7328 When checking for overlap, fix a typo: ZV was used where
7329 ZV_BYTE was intended.
7330 (Fwrite_region): Don't assume off_t fits into 'long'.
7331 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7333 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7335 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7337 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7339 sprintf-related integer and memory overflow issues (Bug#9412).
7341 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7342 (esprintf, exprintf, evxprintf): New functions.
7343 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7344 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7345 (modify_event_symbol): Do not assume that the length of
7346 name_alist_or_stem is safe to alloca and fits in int.
7347 (Fexecute_extended_command): Likewise for function name and binding.
7348 (Frecursion_depth): Wrap around reliably on integer overflow.
7349 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7350 since some callers pass EMACS_INT values.
7351 (Fsingle_key_description): Don't crash if symbol name contains more
7352 than MAX_ALLOCA bytes.
7353 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7354 (get_minibuffer): Arg is now EMACS_INT, not int.
7355 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7356 (esprintf, exprintf, evxprintf): New decls.
7357 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7359 * dbusbind.c (signature_cat): New function.
7360 (xd_signature, Fdbus_register_signal):
7361 Do not overrun buffer; instead, report string overflow.
7363 * dispnew.c (add_window_display_history): Don't overrun buffer.
7364 Truncate instead; this is OK since it's just a log.
7366 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7367 even if the time zone offset is outlandishly large.
7368 Don't mishandle offset == INT_MIN.
7370 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7371 when creating daemon; the previous buffer-overflow check was incorrect.
7373 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7374 which has the guts of the old verror function.
7376 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7377 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7379 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7380 (font_unparse_xlfd): Don't blindly alloca long strings.
7381 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7382 fits in int, when using sprintf. Use single snprintf to count
7383 length of string rather than counting it via multiple sprintfs;
7384 that's simpler and more reliable.
7385 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7386 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7387 sprintf, in case result does not fit in int.
7389 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7390 (fontset_from_font): Print it.
7392 * frame.c (tty_frame_count): Now printmax_t, not int.
7393 (make_terminal_frame, set_term_frame_name): Print it.
7394 (x_report_frame_params): In X, window IDs are unsigned long,
7395 not signed long, so print them as unsigned.
7396 (validate_x_resource_name): Check for implausibly long names,
7397 and don't assume name length fits in 'int'.
7398 (x_get_resource_string): Don't blindly alloca invocation name;
7399 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7402 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7403 (xg_check_special_colors, xg_set_geometry):
7404 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7406 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7407 Use esprintf, not sprintf, in case result does not fit in int.
7409 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7410 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7411 it as a large positive number.
7412 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7413 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7415 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7416 in case result does not fit in int.
7418 * print.c (float_to_string): Detect width overflow more reliably.
7419 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7420 buffer overrun. Don't assume list length fits in 'int'. Treat
7421 print length of 0 as 0, not as infinity; to be consistent with other
7422 uses of print length in this function. Don't overflow print length
7423 index. Don't assume hash table size fits in 'long', or that
7424 vectorlike size fits in 'unsigned long'.
7426 * process.c (make_process): Use printmax_t, not int, to format
7427 process-name gensyms.
7429 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7431 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7432 to avoid potential buffer overrun.
7434 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7435 if X resource line is longer than 512 bytes.
7437 * xfns.c (x_window): Make sprintf buffer a bit bigger
7438 to avoid potential buffer overrun.
7440 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7442 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7444 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7446 Integer overflow fixes for scrolling, etc.
7447 Without these, Emacs silently mishandles large integers sometimes.
7448 For example, "C-u 4294967297 M-x recenter" was treated as if
7449 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7451 * xdisp.c (try_window_id): Check Emacs fixnum range before
7452 converting to 'int'.
7454 * window.c (window_scroll_line_based, Frecenter):
7455 Check that an Emacs fixnum is in range before assigning it to 'int'.
7456 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7457 values converted from Emacs fixnums.
7458 (Frecenter): Don't wrap around a line count if it is out of 'int'
7459 range; instead, treat it as an extreme value.
7460 (Fset_window_configuration, compare_window_configurations):
7461 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7463 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7464 that can exceed INT_MAX. Check that EMACS_INT value is in range
7465 before assigning it to the (possibly-narrower) index.
7466 (match_limit): Don't assume that a fixnum can fit in 'int'.
7468 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7471 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7472 (Fvertical_motion): Don't wrap around LINES values that don't fit
7473 in 'int'. Instead, treat them as extreme values. This is good
7474 enough for windows, which can't have more than INT_MAX lines anyway.
7476 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7478 * Require libxml/parser.h to avoid compilation warning.
7480 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7482 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7483 since this reportedly can destroy thread storage.
7485 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7487 * syntax.c (find_defun_start): Update all cache variables if
7488 exiting early (Bug#9401).
7490 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7492 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7494 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7495 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7496 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7498 * term.c (tty_append_glyph): New function.
7499 (produce_stretch_glyph): Static function and its prototype deleted.
7501 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7504 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7506 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7507 when checking :margin (Bug#9390).
7508 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7509 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7510 so that the name doesn't mislead. All uses changed.
7512 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7514 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7517 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7519 * xdisp.c (move_it_to): Don't bail out early when reaching
7520 position beyond to_charpos, if we are scanning backwards.
7521 (move_it_vertically_backward): When DY == 0, make sure we get to
7522 the first character in the line after the newline.
7524 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7526 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7527 (ccl_driver): Do not generate an out-of-range pointer.
7528 (Fccl_execute_on_string): Remove unnecessary check for
7529 integer overflow, noted by Stefan Monnier in
7530 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7531 Remove a FIXME that didn't need fixing.
7532 Simplify the newly-introduced buffer reallocation code.
7534 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7536 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7538 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7540 Integer and memory overflow issues (Bug#9196).
7542 * doc.c (get_doc_string): Rework so that
7543 get_doc_string_buffer_size is the actual buffer size, rather than
7544 being 1 less than the actual buffer size; this makes xpalloc more
7547 * image.c (x_allocate_bitmap_record, cache_image):
7548 * xselect.c (Fx_register_dnd_atom):
7549 Simplify previous changes by using xpalloc.
7551 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7552 since either will do and ptrdiff_t is convenient with xpalloc.
7554 * charset.c (charset_table_size)
7555 (struct charset_sort_data.priority): Now ptrdiff_t.
7556 (charset_compare): Don't overflow if priorities differ greatly.
7557 (Fsort_charsets): Don't assume list length fits in int.
7558 Check for size-calculation overflow when allocating sort data.
7559 (syms_of_charset): Allocate an initial charset table that is
7560 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7562 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7564 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7565 The actual value is always <= INT_MAX, and leaving it unsigned made
7566 overflow checking harder.
7568 * dispextern.h (struct glyph_matrix.rows_allocated)
7569 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7570 with xpalloc. The values are still always <= INT_MAX.
7572 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7574 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7575 (SAFE_NALLOCA): New macro.
7577 * region-cache.c (struct boundary.pos, find_cache_boundary)
7578 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7579 (set_cache_region, invalidate_region_cache)
7580 (revalidate_region_cache, know_region_cache, region_cache_forward)
7581 (region_cache_backward, pp_cache):
7582 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7583 so that ptrdiff_t * can be passed to xpalloc.
7584 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7585 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7586 (pp_cache): Don't assume cache_len fits in int.
7587 * region-cache.h: Adjust extern decls to match.
7589 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7590 EMACS_INT, since either will do, for xpalloc.
7592 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7593 (xnmalloc, xnrealloc, xpalloc): New functions.
7595 * bidi.c (bidi_shelve_header_size): New constant.
7596 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7597 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7599 * bidi.c (bidi_cache_shrink):
7600 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7602 Don't update size of array until after memory allocation succeeds,
7603 because xmalloc/xrealloc may not return.
7604 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7605 now that we have proper integer overflow checking.
7606 (record_overlay_string, overlay_strings): Catch overflows when
7607 calculating size of overlay_str_buf.
7609 * callproc.c (Fcall_process): Check for size overflow when
7610 calculating size of args2.
7611 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7612 Normally we prefer signed values, but sticking with ptrdiff_t would
7613 require adding more-complicated checks.
7615 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7616 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7617 Redo buffer-overflow calculations to avoid integer overflow.
7618 Add a FIXME comment where memory seems to be over-allocated.
7620 * character.c (Fstring): Check for size-calculation overflow.
7622 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7623 unnecessary integer overflow. Check for size overflow.
7624 (encode_coding_object): Don't update size until xmalloc succeeds.
7626 * composite.c (get_composition_id): Check for overflow in glyph
7627 length calculations.
7629 Integer and memory overflow fixes for display code.
7630 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7631 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7632 (scrolling_window): Check for overflow in size calculations.
7633 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7634 Don't assume glyph table len fits in int.
7635 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7636 (row_table_size): Now ptrdiff_t, not int.
7637 (scrolling_window): Avoid overflow in size calculations.
7638 Don't update size until allocation succeeds.
7639 * fns.c (concat): Check for overflow in size calculations.
7640 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
7641 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7642 (NEXT_ALMOST_PRIME_LIMIT): New constant.
7644 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7645 (get_doc_string): Check for size calculation overflow.
7646 Don't update size until allocation succeeds.
7647 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7648 EMACS_INT, where ptrdiff_t will do.
7649 (Fsubstitute_command_keys): Check for string overflow.
7651 * editfns.c (set_time_zone_rule): Don't assume environment length
7653 (message_length): Now ptrdiff_t, not int.
7654 (Fmessage_box): Don't update size until allocation succeeds.
7655 Don't assume message length fits in int.
7656 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7658 * emacs.c (main): Do not reallocate argv, since there is a null at
7659 the end that can be overwritten, and this way there's no need to
7660 worry about size-calculation overflow.
7661 (sort_args): Check for size-calculation overflow.
7663 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7665 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7667 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7668 (x_set_scroll_bar_width, x_figure_window_size):
7669 Check for integer overflow.
7670 (x_set_alpha): Do not assume XINT fits in int.
7672 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7673 This is for the members text_lines, text_cols, total_lines, total_cols,
7674 where the system imposes an 'int' limit.
7676 * fringe.c (Fdefine_fringe_bitmap):
7677 Don't update size until alloc works.
7679 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7680 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7682 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7683 Check for size-calculation overflow.
7684 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7685 do, as we prefer signed integers.
7686 (id_to_widget.max_size, id_to_widget.used)
7687 (xg_store_widget_in_map, xg_remove_widget_from_map)
7688 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7689 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7690 Use and return ptrdiff_t, not int.
7691 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7692 * gtkutil.h: Change prototypes to match the above.
7694 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7695 are duplicate now that they've been promoted to lisp.h.
7696 (x_allocate_bitmap_record, x_alloc_image_color)
7697 (make_image_cache, cache_image, xpm_load):
7698 Don't update size until alloc is done.
7699 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7701 Check for size calculation overflow.
7702 (ct_colors_allocated_max): New constant.
7703 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
7706 * keyboard.c (read_char, menu_bar_items, tool_bar_items)

7708 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7709 Use ptrdiff_t, not int, to count maps.
7710 (read_char_minibuf_menu_prompt): Check for overflow in size
7711 calculations. Don't update size until allocation succeeds.
7712 Redo calculations to avoid overflow.
7713 * keyboard.h: Change prototypes to match the above.
7715 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

7722 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
7723 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7725 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7726 Now ptrdiff_t, not int.
7727 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
7728 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
7730 * process.c (Fnetwork_interface_list): Check for overflow
7731 in size calculation.
7733 * region-cache.c (move_cache_gap): Check for size calculation overflow.
7735 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
7736 overflow. Don't bother calling xmalloc when xrealloc will do.
7738 * search.c (Freplace_match): Check for size calculation overflow.
7739 (Fset_match_data): Don't assume list lengths fit in 'int'.
7741 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7742 for command line length. Do not attempt to address one before the
7743 beginning of an array, as that's not portable.
7745 * term.c (max_frame_lines): Remove; unused.
7746 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7748 (encode_terminal_code, calculate_costs): Check for size
7749 calculation overflow.
7750 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
7751 table lengths and related sizes. Don't update size until alloc
7752 done. Redo calculations to avoid overflow.
7753 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7755 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
7756 subtracting pointers.

7771 Use ptrdiff_t, not int, for sizes.
7772 (Finternal_make_lisp_face, cache_face):
7773 Check for size calculation overflow.
7774 (cache_face): Treat size calculation overflows as if they were
7775 memory exhaustion (the usual treatment), rather than aborting.
7777 * xfns.c (x_encode_text, x_set_name_internal)
7778 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7779 sizes, since they can exceed INT_MAX in size. Check for size
7780 calculation overflow.
7782 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
7783 (xg_select): Check for size calculation overflow.
7784 Don't update size until alloc done.
7786 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7787 as sprintf is limited to int lengths.
7789 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7790 (X_LONG_MIN): New macros.
7791 Use them to make the following changes clearer.
7792 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7793 This change doesn't affect the value now, but it may help remind
7794 future maintainers not to raise the value too much later.
7795 (SELECTION_QUANTUM): Remove, replacing with ...
7796 (selection_quantum): ... new function, which avoids overflow.
7798 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7799 assumption that selection length fits in 'int'.
7800 (x_reply_selection_request, x_handle_selection_request)
7801 (x_get_window_property, receive_incremental_selection)

7807 Redo calculations to avoid overflow.
7808 (x_reply_selection_request): When sending hint, ceiling it at
7809 X_LONG_MAX rather than relying on wraparound overflow to send

7812 (lisp_data_to_selection_data, x_property_data_to_lisp):
7813 Check for size-calculation overflow.

7816 Don't store size until memory allocation succeeds.
7817 (x_get_window_property): Plug memory leak on memory exhaustion.
7818 Don't double-block input; malloc is safe here. Don't assume 2**34
7819 - 4 fits in unsigned long. Add an xassert to check
7820 XGetWindowProperty overflow. Be more careful about overflow
7821 calculations, and distinguish size from memory overflow better.
7822 (receive_incremental_selection): When tracing, don't assume
7823 unsigned int is less than INT_MAX.
7824 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7825 harmful) conversions of unsigned short to int.
7826 (lisp_data_to_selection_data): Don't assume that integers
7827 in the range -65535 through -1 fit in an X unsigned short.
7828 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7829 result parameters unless successful. Rely on cons_to_unsigned
7830 to report problems with elements; the old code wasn't right anyway.
7831 (x_check_property_data): Check for int overflow; we cannot use
7832 a wider type due to X limits.
7833 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7835 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7837 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7838 (x_term_init): Check for size calculation overflow.
7839 (x_color_cells): Don't store size until memory allocation succeeds.

7864 * image.c (xpm_get_color_table_h):
7865 * lisp.h (hash_lookup, hash_put):
7866 * minibuf.c (Ftest_completion):
7867 Use ptrdiff_t for hash table indexes, not int (which is too
7868 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7869 32-bit --with-wide-int hosts).
7871 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7872 Add a FIXME comment about memory leaks.
7873 (syms_of_charset): Don't assume xmalloc returns.

7877 * character.h (CHAR_WIDTH):
7878 * indent.c (MULTIBYTE_BYTES_WIDTH):
7879 Use sanitize_char_width to avoid undefined and/or bad behavior
7880 with outlandish widths.
7881 * character.h (sanitize_tab_width): Rename from sanitize_width,
7882 now that we have two such functions. All uses changed.
7883 (sanitize_char_width): New inline function.
7885 Don't assume that tab-width fits in int.
7886 * character.h (sanitize_width): New inline function.
7887 (SANE_TAB_WIDTH): New macro.

7901 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7902 (x_send_scroll_bar_event): Likewise. Check that the size does not
7903 exceed limits imposed by XClientMessageEvent, as well as the usual
7904 ptrdiff_t and size_t limits.
7906 * keyboard.c: Overflow, signedness and related fixes.
7907 (make_lispy_movement): Use same integer type in forward decl
7908 that is used in the definition.
7909 (read_key_sequence, keyremap_step):
7910 Change bufsize argument back to int, undoing my 2011-03-30 change.
7911 We prefer signed types, and int is wide enough here.
7912 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7913 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7914 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7915 length, not size_t. Use ptrdiff_t for index, not int.
7916 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7917 possibility of integer overflow.
7919 Overflow, signedness and related fixes for images.

7929 * xdisp.c (calc_pixel_width_or_height):
7930 * xfns.c (image_cache_refcount):
7931 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7932 on typical 64-bit hosts.
7934 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7935 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

7940 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7941 (lookup_image): Remove unnecessary tests.
7942 (xbm_image_p): Locals are now of int, not EMACS_INT,
7943 since parse_image_check makes sure they fit into int.
7944 (png_load, gif_load, svg_load_image):
7945 Prefer int to unsigned where either will do.
7946 (tiff_handler): New function, combining the cores of the
7947 old tiff_error_handler and tiff_warning_handler.
7948 This function is rewritten to use vsnprintf and thereby avoid
7949 stack buffer overflows. It uses only the features of vsnprintf
7950 that are common to both POSIX and native Microsoft.
7951 (tiff_error_handler, tiff_warning_handler): Use it.
7952 (tiff_load, gif_load, imagemagick_load_image):
7953 Don't assume :index value fits in 'int'.
7954 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7955 (imagemagick_load_image): Check that crop parameters fit into
7956 the integer types that MagickCropImage accepts. Don't assume
7957 Vimagemagick_render_type has a nonnegative value. Don't assume
7958 size_t fits in 'long'.
7959 (gs_load): Use printmax_t to print the widest integers possible.

7969 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7970 the display spec is of the form `(space ...)'.
7971 (handle_display_spec): Return the value returned by
7972 handle_single_display_spec, not just 1 or zero.
7973 (handle_single_display_spec): If the display spec is of the form
7974 `(space ...)', and specifies display in the text area, return 2
7976 (try_cursor_movement): Check for the need to scroll more
7977 accurately, and prefer exact match for point under bidi.
7978 Don't advance `row' beyond the last row of the window.
7980 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7981 into disp_prop; all users changed.
7983 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7984 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7985 for the text covered by the display property.
7987 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7989 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7996 buffers, return left-to-right.
7997 (set_cursor_from_row): Consider candidate row a win if its glyph
7998 represents a newline and point is on that newline. Fixes cursor
7999 positioning on the newline at EOL of R2L text within L2R
8000 paragraph, and vice versa.
8001 (try_cursor_movement): Check continued rows, in addition to
8002 continuation rows. Fixes unwarranted scroll when point enters a
8003 continued line of R2L text within an L2R paragraph, or vice versa.
8004 (cursor_row_p): Consider the case of point being equal to
8005 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8006 from the end of a short line to the beginning of a continued line
8007 of R2L text within L2R paragraph.
8008 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8009 composed characters.

8024 2011-08-22 Kenichi Handa <handa@m17n.org>
8026 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8027 extra slot even if the purpose is char-code-property-table.
8029 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8031 * xdisp.c (redisplay_window): When computing centering_position,
8032 account for the height of the header line. (Bug#8874)
8034 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8035 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8036 candidate is selected by the mouse, and that candidate has a
8037 composed character under the mouse.
8039 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8040 coordinates reported by pos-visible-in-window-p for a composed
8041 character in column zero.

8050 consider it a hit if to_charpos is anywhere in the range of the
8051 composed buffer positions.
8053 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8055 * image.c (gif_load): Don't assume that each subimage has the same
8056 dimensions as the base image. Handle disposal method that is
8057 "undefined" by the gif spec (Bug#9335).
8059 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8061 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8062 (Fcondition_case): Document `debug' symbol in error handler.
8064 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8066 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8067 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8068 from an Org mode buffer to a Speedbar frame.
8070 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8071 a composition, take its buffer position from IT->cmp_it.charpos.
8072 Fixes cursor positioning at the beginning of a line that begins
8073 with a composed character.
8075 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8077 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8078 character bidirectional type, use STRONG_L instead. Fixes crashes
8079 in a buffer produced by `describe-categories'.
8081 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8082 members before the level stack, so they would be saved and
8083 restored when copying iterator state. Fixes incorrect reordering
8084 around TABs covered by display properties.
8086 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8088 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8160 ppos_it. Fixes vertical cursor motion when line beginning is
8161 covered by an image. (Bug#9296)
8163 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8165 * nsterm.h (ns_run_ascript): Declare.

8169 (ns_run_ascript): New function.
8170 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8171 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8172 the event loop. Get status from as_status (Bug#7276).
8174 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8175 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8176 the event loop (Bug#7276).

8201 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8202 (Fnetwork_interface_list): Allocate in increments of bytes instead
8203 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8204 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8206 (struct ifflag_def): notrailers is smart on OSX.
8207 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8208 Get hardware address with getifaddrs if available.
8210 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8212 * xdisp.c (iterate_out_of_display_property): xassert that
8213 IT->position is set to within IT->object's boundaries. Break from
8214 the loop as soon as EOB is reached; avoids infloops in redisplay
8215 when IT->position is set up wrongly due to some bug.
8216 Set IT->current to match the bidi iterator unconditionally.
8217 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8218 entry. Force push_it to save on the stack the current
8219 buffer/string position, to be restored by pop_it. Fix flags in
8220 the iterator structure wrt the object coming from a display
8221 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8222 properties. (Bug#9284)
8224 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8226 * fontset.c (fontset_get_font_group): Add proper type checks.
8229 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8231 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8232 and LC_VERSION_MIN_MACOSX.
8233 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8234 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8236 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8238 * xdisp.c (forward_to_next_line_start): Allow to use the
8239 no-display-properties-and-no-overlays under bidi display.
8240 Set disp_pos in the bidi iterator to avoid searches for display
8241 properties and overlays.
8243 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8245 * editfns.c (Fset_time_zone_rule): Document relationship with the
8248 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8249 the font entity extracted from the cache (Bug#8109).
8251 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8253 * composite.c (autocmp_chars): Don't reset point. That is done by
8254 restore_point_unwind (Bug#5984).
8256 2011-08-07 Juri Linkov <juri@jurta.org>
8258 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8259 to show the arg `TIME' instead of `TIMEVAL'.
8261 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8263 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8264 display property strides EOL and includes a newline, as in
8265 longlines-mode. (Bug#9254)
8266 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8267 word-wrap under bidirectional display. (Bug#9224)
8269 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8270 is non-zero, even if the data buffer is NULL. Fixes a crash in
8271 vertical-motion with longlines-mode. (Bug#9254)
8273 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8275 * bidi.c <bidi_cache_total_alloc>: Now static.
8276 (bidi_initialize): Initialize bidi_cache_total_alloc.
8278 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8281 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8282 amount allocated this far in `bidi_cache_total_alloc'.
8283 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8284 non-zero, only free the data buffer without restoring the cache
8285 contents. All callers changed.
8287 * dispextern.h (bidi_unshelve_cache): Update prototype.
8289 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8290 (move_it_in_display_line, move_it_to)
8291 (move_it_vertically_backward, move_it_by_lines): Replace the call
8292 to xfree to an equivalent call to bidi_unshelve_cache.
8293 (move_it_in_display_line_to): Fix logic of returning
8294 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8296 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8298 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8299 came from a string character with a `cursor' property. (Bug#9229)
8301 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8303 * Makefile.in (LIB_PTHREAD): New variable.
8304 (LIBES): Add LIB_PTHREAD (Bug#9216).
8306 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8307 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8309 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8311 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8313 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8315 * xterm.c (x_find_topmost_parent): New function.
8316 (x_set_frame_alpha): Find topmost parent window with
8317 x_find_topmost_parent and set the property there also (bug#9181).
8318 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8320 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8322 * callproc.c (Fcall_process): Avoid vfork clobbering
8323 the local vars buffer, coding_systems, current_dir.
8325 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8327 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8329 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8331 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8332 so that it is not optimized away.
8334 * xdisp.c (compute_display_string_pos): Remove unused local.
8336 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8338 Fix slow cursor motion and scrolling in large buffers with
8339 selective display, like Org Mode buffers. (Bug#9218)
8341 * dispextern.h (struct bidi_it): New member disp_prop_p.
8343 * xdisp.c: Remove one-slot cache of display string positions.
8344 (compute_display_string_pos): Accept an additional argument
8345 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8346 for a display string or property. If found, set DISP_PROP_P
8349 * bidi.c (bidi_fetch_char): Accept an additional argument
8350 DISP_PROP_P, and pass it to compute_display_string_pos.
8351 Only handle text covered by a display string if DISP_PROP_P is returned
8352 non-zero. All callers of bidi_fetch_char changed.
8354 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8356 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8358 2010-12-03 Don March <don@ohspite.net>
8360 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8361 last character M-[char] is translated to ESC [char] (bug#7541).
8363 2011-08-02 Kenichi Handa <handa@m17n.org>
8365 * lisp.h (uniprop_table): Extern it.
8367 * chartab.c (uniprop_table): Make it non-static.
8369 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8371 * xdisp.c (forward_to_next_line_start): Accept additional argument
8372 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8374 (reseat_at_next_visible_line_start): Use the bidi iterator state
8375 returned by forward_to_next_line_start to restore the state of
8376 it->bidi_it after backing up to previous newline. (Bug#9212)
8378 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8380 * regex.c (re_comp): Protoize.
8381 (re_exec): Fix return type.
8382 (regexec): Fix type of `ret'. (Bug#9203)
8384 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8386 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8387 This is needed if max-image-size is a floating-point number.
8389 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8391 * print.c (print_object): Print empty symbol as ##.
8393 * lread.c (read1): Read ## as empty symbol.
8395 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8397 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8398 setting frame foreground color (Bug#9175).
8399 (x_set_background_color): Likewise.
8401 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8402 contents (Bug#9176).
8403 (EmacsTooltip -init): Remove bezels and add shadows to
8406 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8407 or scroll bar (Bug#8470).
8409 * nsfont.m (nsfont_open): Remove assignment to voffset and
8410 unnecessary vars hshink, expand, hd, full_height, min_height.
8411 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8413 * nsterm.h (nsfont_info): Remove voffset field.
8415 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8417 Implement strike-through and overline on NextStep (Bug#8863).
8419 * nsfont.m (nsfont_open): Use underline position provided by font,
8420 instead of hard-coded value of 2.
8421 (nsfont_draw): Call ns_draw_text_decoration instead.
8423 * nsterm.h: Add declaration for ns_draw_text_decoration.
8425 * nsterm.m (ns_draw_text_decoration): New function for drawing
8426 underline, overline, and strike-through.
8427 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8428 ns_draw_text_decoration. Change treatment of cursor drawing to
8429 accommodate underlining, etc.
8431 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8433 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8436 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8438 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8439 Without this fix, if a signal arrives just after memory fills up,
8440 'malloc' might be invoked reentrantly.
8442 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8443 In other words, assume that every image size is allowed, on non-X
8444 hosts. This assumption is probably wrong, but it lets Emacs compile.
8446 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8448 * regex.c (re_iswctype): Convert return values to boolean.
8450 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8452 * xdisp.c (compute_display_string_pos): Don't use cached display
8453 string position if the buffer had its restriction changed.
8456 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8458 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8460 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8462 Integer signedness and overflow and related fixes. (Bug#9079)
8464 * bidi.c: Integer size and overflow fixes.
8465 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8466 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8467 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8468 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8469 (bidi_find_other_level_edge):
8470 Use ptrdiff_t instead of EMACS_INT where either will do.
8471 This works better on 32-bit hosts configured --with-wide-int.
8472 (bidi_cache_ensure_space): Check for size-calculation overflow.
8473 Use % rather than repeated addition, for better worst-case speed.
8474 Don't set bidi_cache_size until after xrealloc returns, because it
8476 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8477 (bidi_cache_ensure_space): Also check that the bidi cache size
8478 does not exceed that of the largest Lisp string or buffer. See Eli
8479 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8481 * alloc.c (__malloc_size_t): Remove.
8482 All uses replaced by size_t. See Andreas Schwab's note
8483 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8485 * image.c: Improve checking for integer overflow.
8486 (check_image_size): Assume that f is nonnull, since
8487 it is always nonnull in practice. This is one less thing to
8488 worry about when checking for integer overflow later.
8489 (x_check_image_size): New function, which checks for integer
8490 overflow issues inside X.
8491 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8492 This removes the need for a memory_full check.
8493 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8494 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8495 (xbm_read_bitmap_data): Change locals back to 'int', since
8496 their values must fit in 'int'.
8497 (xpm_load_image, png_load, tiff_load):
8498 Invoke x_create_x_image_and_pixmap earlier,
8499 to avoid much needless work if the image is too large.
8500 (tiff_load): Treat overly large images as if
8501 x_create_x_image_and_pixmap failed, not as malloc failures.
8502 (gs_load): Use x_check_image_size.
8504 * gtkutil.c: Omit integer casts.
8505 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8506 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8508 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8510 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8511 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8512 would wrongly return t on a 64-bit host.
8514 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8515 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8516 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8517 and therefore cause GCC to emit a bogus diagnostic in some cases.
8519 * image.c: Integer signedness and overflow and related fixes.
8520 This is not an exhaustive set of fixes, but it's time to
8521 record what I've got.
8522 (lookup_pixel_color, check_image_size): Remove redundant decls.
8523 (check_image_size): Don't assume that arbitrary EMACS_INT values
8524 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8525 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8526 (tiff_load, imagemagick_load_image):
8527 Check for overflow in size calculations.
8528 (x_create_x_image_and_pixmap): Remove unnecessary test for
8529 xmalloc returning NULL; that can't happen.
8530 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8531 (xpm_color_bucket): Use better integer hashing function.
8532 (xpm_cache_color): Don't possibly over-allocate memory.
8533 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8534 (gif_memory_source):
8535 Use ptrdiff_t, not int or size_t, to record sizes.
8536 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8537 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8538 either works, as we prefer signed integers.
8539 (tiff_read_from_memory, tiff_write_from_memory):
8540 Return tsize_t, not size_t, since that's what the TIFF API wants.
8541 (tiff_read_from_memory): Don't fail simply because the read would
8542 go past EOF; instead, return a short read.
8543 (tiff_load): Omit no-longer-needed casts.
8544 (Fimagemagick_types): Don't assume size fits into 'int'.
8546 Improve hashing quality when configured --with-wide-int.
8547 * fns.c (hash_string): New function, taken from sxhash_string.
8548 Do not discard information about ASCII character case; this
8549 discarding is no longer needed.
8550 (sxhash-string): Use it. Change sig to match it. Caller changed.
8551 * lisp.h: Declare it.
8552 * lread.c (hash_string): Remove, since we now use fns.c's version.
8553 The fns.c version returns a wider integer if --with-wide-int is
8554 specified, so this should help the quality of the hashing a bit.
8556 * emacs.c: Integer overflow minor fix.
8557 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8558 Define only if GNU_LINUX.
8559 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8561 * dispnew.c: Integer signedness and overflow fixes.
8562 Remove unnecessary forward decls, that were a maintenance hassle.
8563 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8565 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8566 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8567 (prepare_desired_row, line_draw_cost):
8568 Use int, not unsigned, where either works.
8569 (save_current_matrix, restore_current_matrix):
8570 Use ptrdiff_t, not size_t, where either works.
8571 (init_display): Check for overflow more accurately, and without
8572 relying on undefined behavior.
8574 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8575 Remove, replacing with the new symbols in lisp.h. All uses changed.
8576 * fileio.c (make_temp_name):
8577 * filelock.c (lock_file_1, lock_file):
8578 * xdisp.c (message_dolog):
8579 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8580 Use pMd etc. instead.
8581 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8582 replacing the pWIDE etc. symbols removed from editfns.c.
8584 * keyboard.h (num_input_events): Now uintmax_t.
8585 This is (very slightly) less likely to mess up due to wraparound.
8588 * buffer.c: Integer signedness fixes.
8589 (alloc_buffer_text, enlarge_buffer_text):
8590 Use ptrdiff_t rather than size_t when either will do, as we prefer
8593 * alloc.c: Integer signedness and overflow fixes.
8594 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8595 (__malloc_size_t): Default to size_t, not to int.
8596 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8597 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8598 Prefer ptrdiff_t to size_t when either would do, as we prefer
8600 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8601 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8602 Now const. Initialize with values that are in range even if char
8604 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8605 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8606 These functions do the right thing with sizes > 2**32.
8607 (check_depth): Now ptrdiff_t, not int.
8608 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8609 Adjust to new way of storing sizes. Check for size overflow bugs
8611 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8612 slightly wrong anyway, as it missed one instance of
8613 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8614 (refill_memory_reserve): Omit needless cast to size_t.
8615 (mark_object_loop_halt): Mark as externally visible.
8617 * xselect.c: Integer signedness and overflow fixes.
8618 (Fx_register_dnd_atom, x_handle_dnd_message):
8619 Use ptrdiff_t, not size_t, since we prefer signed.
8620 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8621 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8622 x_dnd_atoms_size and x_dnd_atoms_length.
8624 * doprnt.c: Prefer signed to unsigned when either works.
8626 * doprnt.c (doprnt):
8628 * xdisp.c (vmessage):
8629 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8630 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8631 prefer signed arithmetic to avoid comparison confusion.
8632 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8633 but is a bit tricky.
8635 Assume freestanding C89 headers, string.h, stdlib.h.
8636 * data.c, doprnt.c, floatfns.c, print.c:
8637 Include float.h unconditionally.
8638 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8639 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8640 * regex.c: Likewise for stddef.h, string.h.
8641 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8642 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8643 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8644 (STDC_HEADERS): Remove obsolete defines.
8645 * sysdep.c: Include limits.h unconditionally.
8647 Assume support for memcmp, memcpy, memmove, memset.
8648 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8649 * regex.c (memcmp, memcpy):
8650 Remove; we assume C89 now.
8652 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8653 (__malloc_safe_bcopy): Remove; no longer needed.
8655 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8656 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8657 well either way, and we prefer signed to unsigned.
8659 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8661 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8662 closes the connection while we're reading (bug#9182).
8664 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8666 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8667 are specified (Bug#9168).
8669 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8671 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8672 Found by GCC static checking and --with-wide-int on a 32-bit host.
8674 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8676 * xdisp.c (compute_display_string_pos): Fix logic of caching
8677 previous display string position. Initialize cached_prev_pos to
8678 -1. Fixes slow-down at the beginning of a buffer.
8680 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8682 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8683 for attrs[LFACE_FONTSET_INDEX].
8685 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8687 * xml.c (parse_region): Remove unused local
8688 that was recently introduced.
8690 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8692 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8693 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8695 * xdisp.c (move_it_in_display_line_to): Record the best matching
8696 position for TO_CHARPOS while scanning the line, and restore it on
8697 exit if none of the characters scanned was an exact match.
8698 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8699 when exact match is impossible due to invisible text, and the
8700 lines are truncated.
8702 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8704 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8707 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8709 Fix a significant slow-down of cursor motion with C-n, C-p,
8710 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8711 auto-repeat under bidi redisplay in fontified buffers.
8712 * xdisp.c (compute_stop_pos_backwards): New function.
8713 (next_element_from_buffer): Call compute_stop_pos_backwards to
8714 find a suitable prev_stop when we find ourselves before
8716 (reseat): Don't look for prev_stop, as that could mean a very long
8718 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8719 <cached_disp_overlay_modiff>: Cache for last found display string
8721 (compute_display_string_pos): Return the cached position if asked
8722 about the same buffer in the same area of character positions, and
8723 the buffer wasn't changed since the time the display string
8724 position was cached.
8726 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8728 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8729 is an integer, which is important for empty lines. (Bug#9149)
8731 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8733 * frame.c (Fmodify_frame_parameters): In tty case, update the
8734 default face if necessary (Bug#4238).
8736 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8738 * editfns.c (Fstring_to_char): No need to explain what a character
8739 is in the docstring (Bug#6576).
8741 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8743 * xml.c (parse_region): Make sure we always return a tree.
8745 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8747 * xml.c (parse_region): If a document contains only comments,
8750 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8752 * xml.c (make_dom): Return comments, too.
8754 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8757 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8758 and the surrounding thread.
8759 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8760 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8761 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8763 * s/openbsd.h (BROKEN_SIGIO): Define.
8764 * unexelf.c (unexec) [__OpenBSD__]:
8765 Don't update the .mdebug section of the Alpha COFF symbol table.
8767 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8769 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8772 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8774 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8775 This fixes some race conditions on the permissions of any newly
8778 * alloc.c (valid_pointer_p): Use pipe, not open.
8779 This fixes some permissions issues when debugging.
8781 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8782 If fchown fails to set both uid and gid, try to set just gid,
8783 as that is sometimes allowed. Adjust the file's mode to eliminate
8784 setuid or setgid bits that are inappropriate if fchown fails.
8786 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8788 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8789 to compare Lisp_Objects.

8800 symbol character follows.
8802 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8804 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8805 This works around a problem with the previous change to Fcopy_file.
8806 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8807 and without this change, GCC might complain about discarding
8808 fchown's return value.
8810 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8812 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8814 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8816 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8818 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8820 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8821 it's used from the C level.
8823 * process.c: Use the same condition for POLL_FOR_INPUT in both
8824 keyboard.c and process.c (bug#1858).
8826 2011-07-09 Lawrence Mitchell <wence@gmx.li>

8833 * doc.c (Fsubstitute_command_keys): Revert last change.
8835 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8837 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8838 quotes the next character, and doesn't affect other longer
8839 sequences (bug#8935).
8841 * lread.c (syms_of_lread): Clarify that is isn't only
8842 `eval-buffer' and `eval-defun' that's affected by
8843 `lexical-binding' (bug#8460).
8845 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8847 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8848 bidi redisplay when a line includes both an image and is truncated.
8850 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8852 Fix minor problems found by static checking.
8853 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8854 (elsz): Now a signed constant, not a size_t var. We prefer signed
8855 types to unsigned, to avoid integer comparison confusion. Without
8856 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8857 "cannot optimize loop, the loop counter may overflow", a symptom
8859 * indent.c (Fvertical_motion): Mark locals as initialized.
8860 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8862 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8864 * search.c (Fre_search_backward): Mention `case-fold-search' in
8865 all the re_search_* functions (bug#8138).

8883 Initialize itb.string.lstring.
8884 (init_iterator): Call bidi_init_it only of a valid
8885 buffer position was specified. Initialize paragraph_embedding to
8887 (reseat_to_string): Initialize the bidi iterator.
8888 (display_string): If we need to ignore text properties of
8889 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

8894 (compute_display_string_end): Support display properties on Lisp
8896 (init_iterator, reseat_1, reseat_to_string): Initialize the
8897 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8898 when iterating on a string not from display properties).

8900 Fix calculation of the object to scan. Fixes an error when using
8902 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8903 base_level_stop; instead, set base_level_stop to BEGV.
8904 Fixes crashes in vertical-motion.
8905 (next_element_from_buffer): Improve commentary for when
8906 the iterator is before prev_stop.
8907 (init_iterator): Initialize bidi_p from the default value of
8908 bidi-display-reordering, not from buffer-local value. Use the
8909 buffer-local value only if initializing for buffer iteration.
8910 (handle_invisible_prop): Support invisible properties on strings
8911 that are being bidi-reordered.
8912 (set_iterator_to_next): Support bidi reordering of C strings and

8930 parts of next_element_from_buffer, next_element_from_string, and
8931 next_element_from_c_string.
8932 (tool_bar_lines_needed, redisplay_tool_bar)
8933 (display_menu_bar): Force left-to-right direction. Add a FIXME

8948 pushed the iterator stack, restore the internal state of the bidi
8949 iterator by calling bidi_pop_it same number of times.
8950 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8951 and we are bidi-iterating, don't decrement the iterator position;
8952 instead, set the first_elt flag in the bidi iterator, to produce
8954 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8955 (push_display_prop): xassert that we are iterating a buffer.

8962 (compute_display_string_end): Fix handling the case of C string.
8963 (push_it, pop_it): Save and restore from_disp_prop_p.
8964 (handle_single_display_spec, push_display_prop): Set the
8965 from_disp_prop_p flag.
8966 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9016 changed. Support iteration over a string. Support strings with
9017 display properties. Support unibyte strings. Fix the type of

9117 The old code sometimes used this field without initializing it.
9119 * alloc.c (gc_sweep): Don't read past end of array.
9120 In theory, the old code could also have corrupted Emacs internals,
9121 though it'd be very unlikely.
9123 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
9125 * character.c (Fcharacterp): Don't advertise optional ignored

9384 (clone_per_buffer_values): Don't assume that
9385 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).

9425 Random fixes. E.g., (random) never returned negative values.
9426 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9427 subseconds part to the entropy, as that's a bit more random.
9428 Prefer signed to unsigned, since the signedness doesn't matter and
9429 in general we prefer signed. When given a limit, use a
9430 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9431 latter isn't right if USE_2_TAGS_FOR_INTS.
9432 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9433 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9445 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9446 This is more efficient than Ffile_directory_p and avoids a minor race.
9448 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9450 * buffer.c (Foverlay_put): Say what the return value is
9453 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9454 is a directory before asking whether to use the file name
9456 (barf_or_query_if_file_exists): Make the "File is a directory"
9457 error be more correct.
9459 * fns.c (Frequire): Remove the mention of the .gz files, since
9460 that's installation-specific, but keep the mention of
9461 `get-load-suffixes'.
9463 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9465 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9476 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9479 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9481 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9540 (syms_of_keymap): Defsubr make-composed-keymap.
9541 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
9542 (parse_menu_item): Trivial simplification.
9544 2011-07-01 Glenn Morris <rgm@gnu.org>
9546 * Makefile.in (SETTINGS_LIBS): Fix typo.
9548 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny patch)

9576 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9578 * eval.c (struct backtrace): Simplify and port the data structure.
9579 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9580 signed bit field, as this assumption is not portable and it makes
9581 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9582 "char debug_on_exit : 1" as this is not portable either; instead,
9583 use the portable "unsigned int debug_on_exit : 1". Remove unused

9752 * print.c (printchar, strout): Check for string overflow.
9753 (PRINTPREPARE, printchar, strout):
9754 Don't set size unless allocation succeeds.
9756 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9757 for sizes. Check for string overflow more accurately.

9770 * lread.c: Integer overflow fixes.
9771 (read_integer): Radix is now EMACS_INT, not int,
9772 to improve quality of diagnostics for out-of-range radices.
9773 Calculate buffer size correctly for out-of-range radices.
9774 (read1): Check for integer overflow in radices, and in
9775 read-circle numbers.
9776 (read_escape): Avoid int overflow.
9777 (Fload, openp, read_buffer_size, read1)

9792 (read_escape): Check for hex character overflow.
9794 2011-06-22 Leo Liu <sdl.web@gmail.com>
9796 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9797 Move to minibuffer.el.
9799 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9801 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9802 The following patches are for when GLYPH_DEBUG && !XASSERT.
9803 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9804 * dispnew.c (flush_stdout):
9805 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9806 Mark as externally visible.
9807 * dispnew.c (check_window_matrix_pointers): Now static.
9808 * dispnew.c (window_to_frame_vpos):
9809 * xfns.c (unwind_create_frame):
9810 * xterm.c (x_check_font): Remove unused local.
9811 * scroll.c (CHECK_BOUNDS):
9812 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9813 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9814 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.

9816 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9818 (debug_method_add): Use va_list and vsprintf rather than relying
9819 on undefined behavior with wrong number of arguments.
9820 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9821 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9822 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9823 since we're not interested in debugging glyphs with old libraries.
9824 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9825 GCC 4.6.0's static checking.
9827 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9829 Integer overflow and signedness fixes (Bug#8873).

9846 (.bitmaps_last, struct x_output.icon_bitmap):
9847 Use ptrdiff_t, not int, for bitmap indexes.
9848 (x_allocate_bitmap_record): Check for size overflow.

9851 Use ptrdiff_t, not int, for overlay counts.
9852 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9853 * editfns.c (overlays_around, get_pos_property):

9856 * xfaces.c (face_at_buffer_position):
9857 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9858 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9859 (Fnext_overlay_change, Fprevious_overlay_change)
9860 (mouse_face_overlay_overlaps, Foverlays_in):
9861 Use ptrdiff_t, not int, for sizes.
9862 (overlays_at, overlays_in): Check for size-calculation overflow.
9864 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9866 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9867 (x_session_initialize): Do not assume string length fits in int.
9869 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9870 This is unlikely, but can occur if DPI is outlandish.
9872 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9873 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9875 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9876 * xrdb.c (magic_file_p, search_magic_path):
9877 Omit last arg SUFFIX; it was always 0. All callers changed.
9878 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9880 * xfont.c (xfont_match): Avoid need for strlen.
9882 * xfns.c: Don't assume strlen fits in int.

9885 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9886 not unsigned long, as we prefer signed integers. All callers changed.
9887 Detect integer overflow in repeat count.
9888 (message_dolog): Don't assume print length fits in 39 bytes.
9889 (display_mode_element): Don't assume strlen fits in int.
9891 * termcap.c: Don't assume sizes fit in int and never overflow.
9892 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9893 (gobble_line): Check for size-calculation overflow.
9895 * minibuf.c (Fread_buffer):

9910 * filelock.c: Fix some buffer overrun and integer overflow issues.
9911 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9912 Reformulate so as not to need the command string.
9913 Invoke gzip -cd rather than gunzip, as it's more portable.
9914 (lock_info_type, lock_file_1, lock_file):
9915 Don't assume pid_t and time_t fit in unsigned long.
9916 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9917 (current_lock_owner): Prefer signed type for sizes.
9918 Use memcpy, not strncpy, where memcpy is what is really wanted.
9919 Don't assume (via atoi) that time_t and pid_t fit in int.
9920 Check for time_t and/or pid_t out of range, e.g., via a network share.
9921 Don't alloca where an auto var works fine.
9923 * fileio.c: Fix some integer overflow issues.
9924 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9925 Don't assume string length fits in int.
9926 (directory_file_name): Don't assume string length fits in long.

9948 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9950 * lread.c (invalid_syntax): Omit length argument.
9951 All uses changed. This doesn't fix a bug, but it simplifies the
9952 code away from its former Hollerith-constant appearance, and it's
9953 one less 'int' to worry about when looking at integer-overflow issues.
9954 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9956 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9957 This didn't break anything, but it didn't help either.
9958 It's confusing to put a bogus integer in a place where the actual
9959 value does not matter.
9960 (LIST_END_P): Remove unused macro and its bogus comment.
9961 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9963 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9964 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9966 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9967 We prefer signed types, and the value cannot exceed the EMACS_INT
9968 range anyway (because otherwise the length would not be representable).
9969 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9970 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9971 This avoids a GCC warning when WIDE_EMACS_INT.
9973 * indent.c (sane_tab_width): New function.
9974 (current_column, scan_for_column, Findent_to, position_indentation)
9975 (compute_motion): Use it. This is just for clarity.
9976 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9978 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9980 * lisp.h (lint_assume): New macro.
9981 * composite.c (composition_gstring_put_cache):
9982 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9984 * editfns.c, insdel.c:
9985 Omit unnecessary forward decls, to simplify future changes.
9987 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9989 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9991 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9992 Use much-faster test for byte-length change.
9993 Don't assume string byte-length fits in 'int'.
9994 Check that character arg fits in 'int'.
9995 (mapcar1): Declare byte as byte, for clarity.
9997 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9999 * fns.c (concat): Catch string overflow earlier.
10000 Do not rely on integer wraparound.
10002 * dispextern.h (struct it.overlay_strings_charpos)
10003 (struct it.selective): Now EMACS_INT, not int.
10004 * xdisp.c (forward_to_next_line_start)
10005 (back_to_previous_visible_line_start)
10006 (reseat_at_next_visible_line_start, next_element_from_buffer):
10007 Don't arbitrarily truncate the value of 'selective' to int.
10009 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10011 * composite.c: Don't truncate sizes to 'int'.
10012 (composition_gstring_p, composition_reseat_it)
10013 (composition_adjust_point): Use EMACS_INT, not int.
10014 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10015 not EMACS_UINT, for indexes.
10017 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10019 * buffer.c: Include <verify.h>.
10020 (struct sortvec.priority, struct sortstr.priority):
10021 Now EMACS_INT, not int.
10022 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10023 (struct sortstr.size, record_overlay_string)
10024 (struct sortstrlist.size, struct sortlist.used):
10025 Don't truncate size to int.
10026 (record_overlay_string): Check for size-calculation overflow.
10027 (init_buffer_once): Check at compile-time, not run-time.
10029 2011-06-22 Jim Meyering <meyering@redhat.com>
10031 Don't leak an XBM-image-sized buffer
10032 * image.c (xbm_load): Free the image buffer after using it.
10034 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10037 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10038 that Sun C diagnosed.
10039 * fns.c (secure_hash): Fix pointer signedness issue.
10040 * intervals.c (static_offset_intervals): New function.
10041 (offset_intervals): Use it.
10043 2011-06-21 Leo Liu <sdl.web@gmail.com>
10046 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10049 * fns.c (secure_hash): Rename from crypto_hash_function and change
10050 the first arg to accept symbols.
10051 (Fsecure_hash): New primitive.
10052 (syms_of_fns): New symbols.
10054 2011-06-20 Deniz Dogan <deniz@dogan.se>
10056 * process.c (Fset_process_buffer): Clarify return value in
10059 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10061 * dispnew.c (add_window_display_history): Use BVAR.
10063 * xdisp.c (debug_method_add): Use BVAR.
10064 (check_window_end, dump_glyph_matrix, dump_glyph)
10065 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10067 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10070 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10071 check till after the cache is created in init_frame_faces.
10073 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10075 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10077 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10079 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10080 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10081 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10083 Improve buffer-overflow checking (Bug#8873).
10084 * fileio.c (Finsert_file_contents):
10085 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10086 Remove the old (too-loose) buffer overflow checks.
10087 They weren't needed, since make_gap checks for buffer overflow.
10088 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10089 The old code merely checked for Emacs fixnum overflow, and relied
10090 on undefined (wraparound) behavior. The new code avoids undefined
10091 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10093 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10094 Tune. Don't use wider integers than needed. Don't use alloca.
10095 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10097 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10099 * insdel.c, lisp.h (buffer_overflow): New function.
10100 (insert_from_buffer_1, replace_range, replace_range_2):
10101 * insdel.c (make_gap_larger):
10102 * editfns.c (Finsert_char):
10103 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10105 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10107 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10109 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10111 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10112 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10114 * fileio.c: Don't assume EMACS_INT fits in off_t.
10115 (emacs_lseek): New static function.
10116 (Finsert_file_contents, Fwrite_region): Use it.
10117 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10119 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10121 * fns.c: Don't overflow int when computing a list length.
10122 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10123 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10124 truncation on 64-bit hosts. Check for QUIT every
10125 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10126 faster and is responsive enough.
10127 (Flength): Report an error instead of overflowing an integer.
10128 (Fsafe_length): Return a float if the value is not representable
10129 as a fixnum. This shouldn't happen except in contrived situations.
10130 (Fnthcdr, Fsort): Don't assume list length fits in int.
10131 (Fcopy_sequence): Don't assume vector length fits in int.
10133 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10134 (header_size, word_size): New constants.
10135 (allocate_vectorlike): Don't check size overflow here.
10136 (allocate_vector): Check it here instead, since this is the only
10137 caller of allocate_vectorlike that could cause overflow.
10138 Check that the new vector's length is representable as a fixnum.
10140 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10141 The previous code was bogus. For example, next_almost_prime (32)
10142 returned 39, which is undesirable as it is a multiple of 3; and
10143 next_almost_prime (24) returned 25, which is a multiple of 5 so
10144 why was the code bothering to check for multiples of 7?
10146 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10148 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10150 Variadic C functions now count arguments with ptrdiff_t.
10151 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10152 Back then I didn't know that the Emacs coding style prefers signed int.
10153 Also, in the meantime I found a few more instances where arguments
10154 were being counted with int, which may truncate counts on 64-bit
10155 machines, or EMACS_INT, which may be unnecessarily wide.
10156 * lisp.h (struct Lisp_Subr.function.aMANY)
10157 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10158 Arg counts are now ptrdiff_t, not size_t.
10159 All variadic functions and their callers changed accordingly.
10160 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10161 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10162 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10163 * callint.c (Fcall_interactively): Check arg count for overflow,
10164 to avoid potential buffer overrun. Use signed char, not 'int',
10165 for 'varies' array, so that we needn't bother to check its size
10166 calculation for overflow.
10167 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10168 * eval.c (apply_lambda):
10169 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10170 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10171 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10173 * callint.c (Fcall_interactively): Don't use index var as event count.
10175 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10176 * mem-limits.h (SIZE): Remove; no longer used.
10178 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10180 Remove unnecessary casts.
10181 * xterm.c (x_term_init):
10182 * xfns.c (x_set_border_pixel):
10183 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10184 These aren't needed now that we assume ANSI C.
10186 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10187 It's more likely to cause problems (due to unsigned overflow)
10190 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10192 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10194 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10196 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10198 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10200 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10202 GLYPH_CODE_FACE returns EMACS_INT, not int.
10203 * dispextern.h (merge_faces):
10204 * xfaces.c (merge_faces):
10205 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10206 Don't assume EMACS_INT fits in int.
10208 * character.h (CHAR_VALID_P): Remove unused parameter.
10209 * fontset.c, lisp.h, xdisp.c: All uses changed.
10211 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10213 * fns.c (concat): Minor tuning based on overflow analysis.
10214 This doesn't fix any bugs. Use int to hold character, instead
10215 of constantly refetching from Emacs object. Use XFASTINT, not
10216 XINT, for value known to be a character. Don't bother comparing
10217 a single byte to 0400, as it's always less.
10219 * floatfns.c (Fexpt):
10220 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10222 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10225 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10227 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10228 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10229 incorrectly succeed when S was a string, because 4294967386 was
10230 truncated before it was used.
10232 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10233 Otherwise, an out-of-range integer could cause undefined behavior
10236 * composite.c: Use int, not EMACS_INT, for characters.
10237 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10238 EMACS_INT, for values that are known to be in character range.
10239 This doesn't fix any bugs but is the usual style inside Emacs and
10240 may generate better code on 32-bit machines.
10242 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10243 This is for reasons similar to the recent CHAR_STRING fix.
10244 * charset.c (Fencode_char): Check that character arg is actually
10245 a character. Pass an int to ENCODE_CHAR.
10246 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10247 wider than 'int', as a compile-time check to prevent future regressions
10250 * character.c (char_string): Remove unnecessary casts.
10252 Make sure a 64-bit char is never passed to CHAR_STRING.
10253 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10254 by silently ignoring the top 32 bits, allowing some values
10255 that were far too large to be valid characters.
10256 * character.h: Include <verify.h>.
10257 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10258 arguments are no wider than unsigned, as a compile-time check
10259 to prevent future regressions in this area.
10261 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10262 (Fsubst_char_in_region):
10264 * xdisp.c (decode_mode_spec_coding):
10265 Adjust to CHAR_STRING's new requirement.
10266 * editfns.c (Finsert_char, Fsubst_char_in_region):
10267 * fns.c (concat): Check that character args are actually
10268 characters. Without this test, these functions did the wrong
10269 thing with wildly out-of-range values on 64-bit hosts.
10271 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10272 These casts should not be needed on 32-bit hosts, either.
10273 * keyboard.c (read_char):
10274 * lread.c (Fload): Remove casts to unsigned.
10276 * lisp.h (UNSIGNED_CMP): New macro.
10277 This fixes comparison bugs on 64-bit hosts.
10278 (ASCII_CHAR_P): Use it.
10279 * casefiddle.c (casify_object):
10280 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10281 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10282 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10283 * dispextern.h (FACE_FROM_ID):
10284 * keyboard.c (read_char): Use UNSIGNED_CMP.
10286 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10287 not to EMACS_INT, to avoid GCC warning.
10289 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10291 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10292 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10293 isn't needed on 32-bit machines.
10295 * buffer.c (Fgenerate_new_buffer_name):
10296 Use EMACS_INT for count, not int.
10297 (advance_to_char_boundary): Return EMACS_INT, not int.
10299 * data.c (Qcompiled_function): Now static.
10301 * window.c (window_body_lines): Now static.
10303 * image.c (gif_load): Rename local to avoid shadowing.
10305 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10306 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10307 * alloc.c (make_save_value): Integer argument is now of type
10308 ptrdiff_t, not int.
10309 (mark_object): Use ptrdiff_t, not int.
10310 * lisp.h (pD): New macro.
10311 * print.c (print_object): Use it.
10313 * alloc.c: Use EMACS_INT, not int, to count objects.
10314 (total_conses, total_markers, total_symbols, total_vector_size)
10315 (total_free_conses, total_free_markers, total_free_symbols)
10316 (total_free_floats, total_floats, total_free_intervals)
10317 (total_intervals, total_strings, total_free_strings):
10318 Now EMACS_INT, not int. All uses changed.
10319 (Fgarbage_collect): Compute overall total using a double, so that
10320 integer overflow is less likely to be a problem. Check for overflow
10321 when converting back to an integer.
10322 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10323 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10324 These were 'int' variables that could overflow on 64-bit hosts;
10325 they were never used, so remove them instead of repairing them.
10326 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10327 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10328 Previously, this ceilinged at INT_MAX, but that doesn't work on
10330 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10332 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10333 (allocate_vectorlike): Check for ptrdiff_t overflow.
10334 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10335 when a (possibly-narrower) signed value would do just as well.
10336 We prefer using signed arithmetic, to avoid comparison confusion.
10338 * alloc.c: Catch some string size overflows that we were missing.
10339 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10340 for convenience in STRING_BYTES_MAX.
10341 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10342 The definition here is exact; the one in lisp.h was approximate.
10343 (allocate_string_data): Check for string overflow. This catches
10344 some instances we weren't catching before. Also, it catches
10345 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10346 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10347 and ptrdiff_t and EMACS_INT are both 64 bits.
10349 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10350 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10351 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10353 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10355 * alloc.c (Fmake_string): Check for out-of-range init.
10357 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10359 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10361 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10363 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10364 xg_get_default_scrollbar_width.
10366 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10367 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10368 (style_changed_cb): Call update_theme_scrollbar_width and call
10369 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10370 all frames (Bug#8505).
10371 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10372 Call gtk_window_set_resizable if HAVE_GTK3.
10373 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10374 and height if HAVE_GTK3 (Bug#8505).
10375 (scroll_bar_width_for_theme): New variable.
10376 (update_theme_scrollbar_width): New function.
10377 (xg_get_default_scrollbar_width): Move code to
10378 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10379 (xg_initialize): Call update_theme_scrollbar_width.
10381 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10383 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10385 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10387 * frame.c (make_frame): Call other_buffer_safely instead of
10390 * window.c (temp_output_buffer_show): Call display_buffer with
10391 second argument Vtemp_buffer_show_specifiers and reset latter
10392 immediately after the call.
10393 (Vtemp_buffer_show_specifiers): New variable.
10394 (auto_window_vscroll_p, next_screen_context_lines)
10395 (Vscroll_preserve_screen_position): Remove leading asterisks from
10398 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10400 Fix minor problems found by GCC 4.6.0 static checking.
10401 * buffer.c (Qclone_number): Remove for now, as it's unused.
10402 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10403 (record_buffer): Remove unused local.
10404 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10405 (set_frame_buffer_list): Remove; unused.
10406 * frame.h (other_visible_frames): Remove decl.
10407 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10408 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10409 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10411 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10412 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10413 Define only if HAVE_GPM.
10414 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10415 (update_hints_inhibit): Remove; never set. All uses removed.
10416 * widgetprv.h (emacsFrameClassRec): Remove decl.
10417 * window.c (delete_deletable_window): Now returns void, since it
10418 wasn't returning anything.
10419 (compare_window_configurations): Remove unused locals.
10420 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10421 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10422 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10423 the same widths as pointers. This follows up on the 2011-05-06 patch.
10424 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10425 * xterm.h: Likewise.
10426 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10428 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10430 * makefile.w32-in: Update dependencies.
10431 (LISP_H): Add lib/intprops.h.
10433 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10435 * image.c (gif_load): Add animation frame delay to the metadata.
10436 (syms_of_image): Use DEFSYM. New symbol `delay'.
10438 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10440 * window.c (delete_deletable_window): Re-add.
10441 (Fset_window_configuration): Rewrite to handle dead buffers and
10442 consequently deletable windows.
10443 (window_tree, Fwindow_tree): Remove. Supply functionality in
10445 (compare_window_configurations): Simplify code.
10447 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10449 * image.c (imagemagick_load_image): Fix type mismatch.
10450 (Fimagemagick_types): Likewise.
10452 * window.h (replace_buffer_in_windows): Declare.
10454 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10456 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10457 Qclone_number. Remove external declaration of Qdelete_window.
10458 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10460 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10461 Run Qbuffer_list_update_hook if allowed.
10462 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10463 buffer list implementation.
10464 (other_buffer_safely): New function.
10465 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10466 calls to replace_buffer_in_windows and
10467 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10469 (record_buffer): Inhibit quitting and rewrite using quittable
10470 functions. Run Qbuffer_list_update_hook if allowed.
10471 (Frecord_buffer, Funrecord_buffer): New functions.
10472 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10473 Move switch-to-buffer to window.el.
10474 (bury-buffer): Move to window.el.
10475 (Vbuffer_list_update_hook): New variable.
10477 * lisp.h (other_buffer_safely): Add prototype in buffer.c

10929 (bidi_resolve_explicit, bidi_resolve_weak):
10930 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10931 bidirectional text is supported only in multibyte buffers.
10932 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
10933 it to initialize the frame_window_p member of struct bidi_it.
10934 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
10935 (bidi_resolve_explicit, bidi_resolve_weak)
10936 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
10937 bidi_it->nchars is non-positive.
10938 (bidi_level_of_next_char): Don't try to lookup the cache for the
10939 next/previous character if nothing is cached there yet, or if we
10940 were just reseat()'ed to a new position.
10942 * xdisp.c (set_cursor_from_row): Set start and stop points
10943 according to the row's direction when priming the loop that looks
10944 for the glyph on which to display cursor.
10945 (single_display_spec_intangible_p): Function deleted.
10946 (display_prop_intangible_p): Reimplement to call
10947 handle_display_spec instead of single_display_spec_intangible_p.
10948 Accept 3 additional arguments needed by handle_display_spec.
10949 This fixes incorrect cursor motion across display property with complex
10950 values: lists, `(when COND...)' forms, etc.
10951 (single_display_spec_string_p): Support property values that are
10952 lists with the argument STRING its top-level element.
10953 (display_prop_string_p): Fix the condition for processing a
10954 property that is a list to be consistent with handle_display_spec.
10955 (handle_display_spec): New function, refactored from the
10956 last portion of handle_display_prop.
10957 (compute_display_string_pos): Accept additional argument
10958 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10959 value of a `display' property is a "replacing spec".
10960 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10961 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10962 the display property, but just return a value indicating whether
10963 the display property will replace the characters it covers.
10964 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10965 frame_window_p members of struct bidi_it.
10966 (compute_display_string_pos, compute_display_string_end):
10968 (push_it): Accept second argument POSITION, where pop_it should
10969 jump to continue iteration.
10970 (reseat_1): Initialize bidi_it.disp_pos.
10972 * keyboard.c (adjust_point_for_property): Adjust the call to
10973 display_prop_intangible_p to its new signature.
10975 * dispextern.h (struct bidi_it): New member frame_window_p.
10976 (bidi_init_it): Update prototypes.
10977 (display_prop_intangible_p): Update prototype.
10978 (compute_display_string_pos, compute_display_string_end):
10979 Declare prototypes.
10980 (struct bidi_it): New members nchars and disp_pos. ch_len is now
10983 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
10985 Malloc failure behavior now depends on size of allocation.
10986 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
10987 * lisp.h: Change signatures accordingly.
10988 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
10989 All callers changed. (Bug#8762)
10991 * gnutls.c: Use Emacs's memory allocators.
10992 Without this change, the gnutls library would invoke malloc etc.
10993 directly, which causes problems on non-SYNC_INPUT hosts, and which
10994 runs afoul of improving memory_full behavior. (Bug#8761)
10995 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10996 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10997 xfree instead of the default malloc, realloc, free.
10998 (Fgnutls_boot): No need to check for memory allocation failure,
10999 since xmalloc does that for us.
11001 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11002 * category.c (hash_get_category_set):
11003 * ccl.c (ccl_driver):

11016 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11017 * image.c (make_image, search_image_cache, lookup_image)
11018 (xpm_put_color_table_h):
11019 * lisp.h (struct Lisp_Hash_Table):
11020 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11021 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11022 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11023 * alloc.c (allocate_vectorlike):
11024 Check for overflow in vector size calculations.
11025 * ccl.c (ccl_driver):
11026 Check for overflow when converting EMACS_INT to int.
11027 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11028 need to be updated by these changes.
11029 * fns.c (make_hash_table, maybe_resize_hash_table):
11030 Check for integer overflow with large hash tables.
11031 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11032 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11033 (SXHASH_REDUCE): New macro.
11034 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11035 Use it instead of discarding useful hash info with large hash values.
11036 (sxhash_float): New function.
11037 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11038 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11039 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11040 Rewrite to use FIXNUM_BITS, as this simplifies things.
11041 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11042 Adjust signatures to match updated version of code.
11043 (consing_since_gc): Now EMACS_INT, since a single hash table can
11044 use more than INT_MAX bytes.
11046 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11048 Make it possible to build with GCC-4.6+ -O2 -flto.
11050 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11052 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11054 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11055 Call minibuffer-inactive-mode.
11057 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11059 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11060 Update dependencies.
11062 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11064 * data.c (init_data): Remove code for UTS, this system is not
11067 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11069 Don't force ./temacs to start in terminal mode.
11071 * frame.c (make_initial_frame): Initialize faces in all cases, not
11072 only when CANNOT_DUMP is defined.
11073 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11075 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11077 * dispnew.c (add_window_display_history): Use const for the string
11078 pointer. Remove declaration, not needed.
11080 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11082 Use 'inline', not 'INLINE'.
11083 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11084 * alloc.c, fontset.c (INLINE): Remove.
11085 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11086 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11087 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11088 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11089 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11091 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11093 Make it possible to run ./temacs.
11095 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11096 syms_of_callproc does the same thing. Remove test for
11097 "initialized", do it in the caller.
11098 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11100 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11102 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11103 (read_minibuf): Use get_minibuffer.
11104 (syms_of_minibuf): Use DEFSYM.
11105 (Qmetadata): New var.
11106 * data.c (Qbuffer): Don't make it static.
11107 (syms_of_data): Use DEFSYM.
11109 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11111 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11112 (CCL_CODE_MIN): New macro.
11114 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11116 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11118 * eval.c (Qdebug): Now static.
11119 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11120 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11121 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11123 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11125 * image.c: Various fixes to ImageMagick code comments.
11126 (Fimagemagick_types): Doc fix.
11128 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11130 Minor fixes prompted by GCC 4.6.0 warnings.
11132 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11134 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11135 (x_clipboard_manager_save_all): Move extern decl to ...
11136 * xterm.h: ... here, so that it can be checked for consistency.
11138 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11140 * xselect.c (x_clipboard_manager_save_frame)
11141 (x_clipboard_manager_save_all): New functions.
11142 (Fx_clipboard_manager_save): Lisp function deleted.
11144 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11145 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11147 * xterm.h: Update prototype.
11149 2011-05-28 William Xu <william.xwl@gmail.com>
11151 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11152 exiting (Bug#8239).
11154 2011-05-28 Jim Meyering <meyering@redhat.com>
11156 Avoid a sign-extension bug in crypto_hash_function.
11157 * fns.c (to_uchar): Define.
11158 (crypto_hash_function): Use it to convert some newly-signed
11159 variables to unsigned, to avoid sign-extension bugs. For example,
11160 without this change, (md5 "truc") would evaluate to
11161 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11162 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11163 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11165 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11167 Integer overflow fixes.
11169 * dbusbind.c: Serial number integer overflow fixes.
11170 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11171 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11172 to hold a serial number that is too large for a fixnum.
11173 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11174 Check for serial numbers out of range. Decode any serial number
11175 that was so large that it became a float. (Bug#8722)
11177 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11178 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11179 Use XFASTINT rather than XUINT when numbers are nonnegative.
11180 (xd_append_arg, Fdbus_method_return_internal):
11181 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11182 arguments, check that Lisp number is nonnegative, rather than
11183 silently wrapping negative numbers around. (Bug#8722)
11184 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11187 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11189 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11191 ccl: Add integer overflow checks.
11192 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11193 (IN_INT_RANGE): New macros.
11194 (ccl_driver): Use them to check for integer overflow when
11195 decoding a CCL program. Many of the new checks are whether XINT (x)
11196 fits in int; it doesn't always, on 64-bit hosts. The new version
11197 doesn't catch all possible integer overflows, but it's an
11198 improvement. (Bug#8719)
11200 * alloc.c (make_event_array): Use XINT, not XUINT.
11201 There's no need for unsigned here.
11203 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11204 This follows up to the 2011-05-06 change that substituted uintptr_t
11205 for EMACS_INT. This case wasn't caught back then.
11207 Rework Fformat to avoid integer overflow issues.
11208 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11209 now (part of C89). Include <verify.h>.
11210 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11211 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11212 (Fformat): Avoid the prepass trying to compute sizes; it was only
11213 approximate and thus did not catch overflow reliably. Instead, walk
11214 through the format just once, formatting and computing sizes as we go,
11215 checking for integer overflow at every step, and allocating a larger
11216 buffer as needed. Keep track separately whether the format is
11217 multibyte. Keep only the most-recently calculated precision, rather
11218 than them all. Record whether each argument has been converted to
11219 string. Use EMACS_INT, not int, for byte and char and arg counts.
11220 Support field widths and precisions larger than INT_MAX. Avoid
11221 sprintf's undefined behavior with conversion specifications such as %#d
11222 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11223 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11224 formatting out-of-range floating point numbers with int
11225 formats. (Bug#8668)
11227 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11229 * data.c: Avoid integer truncation in expressions involving floats.
11230 * data.c: Include <intprops.h>.
11231 (arith_driver): When there's an integer overflow in an expression
11232 involving floating point, convert the integers to floating point
11233 so that the resulting value does not suffer from catastrophic
11234 integer truncation. For example, on a 64-bit host (* 4
11235 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11236 Do not rely on undefined behavior after integer overflow.
11238 merge count_size_as_multibyte, parse_str_to_multibyte
11239 * character.c, character.h (count_size_as_multibyte):
11240 Rename from parse_str_to_multibyte; all uses changed.
11241 Check for integer overflow.
11242 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11243 since it's now a duplicate of the other. This is more of
11244 a character than a buffer op, so better that it's in character.c.
11245 * fns.c, print.c: Adjust to above changes.
11247 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11249 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11251 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11253 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11254 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11255 (x_clipboard_manager_save): Now static.
11256 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11258 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11259 (crypto_hash_function): Now static.
11260 Fix pointer signedness problems. Avoid unnecessary initializations.
11262 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11264 * termhooks.h (Vselection_alist): Make it terminal-local.
11266 * terminal.c (create_terminal): Initialize it.
11268 * xselect.c: Support for clipboard managers.
11269 (Vselection_alist): Move to termhooks.h as terminal-local var.
11270 (LOCAL_SELECTION): New macro.
11271 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11272 (symbol_to_x_atom): Remove gratuitous arg.
11273 (x_handle_selection_request, lisp_data_to_selection_data)
11274 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11275 (x_own_selection, x_get_local_selection, x_convert_selection):
11276 New arg, specifying work frame. Use terminal-local Vselection_alist.
11277 (some_frame_on_display): Delete unused function.
11278 (Fx_own_selection_internal, Fx_get_selection_internal)
11279 (Fx_disown_selection_internal, Fx_selection_owner_p)
11280 (Fx_selection_exists_p): New optional frame arg.
11281 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11282 (x_handle_selection_clear): Don't treat other terminals with the
11283 same keyboard specially. Use the terminal-local Vselection_alist.
11284 (x_clear_frame_selections): Use Frun_hook_with_args.
11286 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11288 * xterm.h: Add support for those atoms.
11290 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11292 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11293 (converted_selections, conversion_fail_tag): New global variables.
11294 (x_selection_request_lisp_error): Free the above.
11295 (x_get_local_selection): Remove unnecessary code.
11296 (x_reply_selection_request): Args changed; handle arbitrary array
11297 of converted selections stored in converted_selections.
11298 Separate the XChangeProperty and SelectionNotify steps.
11299 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11300 (x_convert_selection): New function.
11301 (x_handle_selection_event): Simplify.
11302 (x_get_foreign_selection): Don't ignore incoming requests while
11303 waiting for an answer; this will fail when we implement
11304 SAVE_TARGETS, and seems unnecessary anyway.
11305 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11306 (Vx_sent_selection_functions): Doc fix.
11308 2011-05-26 Leo Liu <sdl.web@gmail.com>
11310 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11312 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11314 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11316 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11317 for fringe update if it has periodic bitmap.
11318 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11319 and fringe_bitmap_periodic_p.
11321 * fringe.c (get_fringe_bitmap_data): New function.
11322 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11323 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11324 row. Mark glyph row for fringe update if periodicity changed.
11326 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11327 for fringe update unless it has periodic bitmap.
11329 2011-05-25 Kenichi Handa <handa@m17n.org>
11331 * xdisp.c (get_next_display_element): Set correct it->face_id for
11332 a static composition.
11334 2011-05-24 Leo Liu <sdl.web@gmail.com>

11339 * fns.c (crypto_hash_function, Fsha1): New function.
11340 (Fmd5): Use crypto_hash_function.
11341 (syms_of_fns): Add Ssha1.
11343 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11345 * gnutls.c: Remove unused macros.
11346 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11347 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11348 Remove macros that are defined and never used.

11353 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11354 (Fx_get_selection_internal): Minor cleanup.
11355 (Fx_own_selection_internal): Rename arguments for consistency with
11358 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11360 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11362 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11364 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11366 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11368 * dispnew.c (scrolling_window): Don't exclude the case that the
11369 last enabled row in the desired matrix touches the bottom boundary.
11371 2011-05-21 Glenn Morris <rgm@gnu.org>
11373 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11374 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11375 and add some more files.
11377 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11379 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11380 report_file_error introduced by the change from 2011-05-07.
11382 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11384 * systime.h (Time): Define only if emacs is defined.
11385 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11386 where the include path doesn't have X11/X.h by default. See
11387 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11389 2011-05-20 Kenichi Handa <handa@m17n.org>
11391 * composite.c (find_automatic_composition): Fix previous change.
11393 2011-05-20 Glenn Morris <rgm@gnu.org>
11395 * lisp.mk: New file, split from Makefile.in.
11396 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11397 (shortlisp): Remove.
11398 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11400 2011-05-19 Glenn Morris <rgm@gnu.org>
11402 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11403 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11404 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11405 (lisp): Set the order to that of loadup.el.
11406 (shortlisp): Make it a copy of $lisp.
11407 (SOME_MACHINE_LISP): Remove.
11408 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11409 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11411 2011-05-18 Kenichi Handa <handa@m17n.org>
11413 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11414 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11415 (find_automatic_composition): Mostly rewrite for efficiency.
11417 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11419 * makefile.w32-in: Update dependencies.
11421 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11423 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11424 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11426 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11428 Fix some integer overflow issues, such as string length overflow.
11430 * insdel.c (count_size_as_multibyte): Check for string overflow.
11432 * character.c (lisp_string_width): Check for string overflow.
11433 Use EMACS_INT, not int, for string indexes and lengths; in
11434 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11435 the resulting string length overflows an EMACS_INT; instead,
11436 report a string overflow if no precision given. When checking for
11437 precision exhaustion, use a check that cannot possibly have
11438 integer overflow. (Bug#8675)
11439 * character.h (lisp_string_width): Adjust to new signature.
11441 * alloc.c (string_overflow): New function.
11442 (Fmake_string): Use it. This doesn't change behavior, but saves
11443 a few bytes and will simplify future changes.
11444 * character.c (string_escape_byte8): Likewise.
11445 * lisp.h (string_overflow): New decl.
11447 Fixups, following up to the user-interface timestamp change.
11448 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11449 for UI timestamps, instead of unsigned long.
11450 * msdos.c (mouse_get_pos): Likewise.
11451 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11452 * w32gui.h (Time): Define by including "systime.h" rather than by
11453 declaring it ourselves. (Bug#8664)
11455 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11456 * image.c (clear_image_cache): Likewise.
11458 * term.c (term_mouse_position): Don't assume time_t wraparound.
11460 Be more systematic about user-interface timestamps.
11461 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11462 and sometimes 'EMACS_UINT', to represent these timestamps.
11463 This change causes it to use 'Time' uniformly, as that's what X uses.
11464 This makes the code easier to follow, and makes it easier to catch
11465 integer overflow bugs such as Bug#8664.
11466 * frame.c (Fmouse_position, Fmouse_pixel_position):
11467 Use Time, not unsigned long, for user-interface timestamps.
11468 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11469 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11470 * keyboard.h (last_event_timestamp): Likewise.
11471 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11472 * menu.h (xmenu_show): Likewise.
11473 * term.c (term_mouse_position): Likewise.
11474 * termhooks.h (struct input_event.timestamp): Likewise.
11475 (struct terminal.mouse_position_hook): Likewise.
11476 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11477 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11478 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11479 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11480 what it was before.
11481 * menu.h, termhooks.h: Include "systime.h", for Time.
11483 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11484 Don't assume that the difference between two unsigned long values
11485 can fit into an integer. At this point, we know button_down_time
11486 <= event->timestamp, so the difference must be nonnegative, so
11487 there's no need to cast the result if double-click-time is
11488 nonnegative, as it should be; check that it's nonnegative, just in
11489 case. This bug is triggered when events are more than 2**31 ms
11490 apart (about 25 days). (Bug#8664)
11492 * xselect.c (last_event_timestamp): Remove duplicate decl.
11493 (x_own_selection): Remove needless cast to unsigned long.
11495 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11496 that always fit in int. Use a sentinel instead of a counter, to
11497 avoid a temp and to allay GCC's concerns about possible int overflow.
11498 * frame.h (struct frame): Use int for menu_bar_items_used
11499 instead of EMACS_INT, since it always fits in int.
11501 * menu.c (grow_menu_items): Check for int overflow.
11503 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11505 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11506 Before, the code was not consistent. These values cannot exceed
11507 2**31 - 1 so there's no need to make them unsigned.
11508 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11509 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11510 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11512 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11514 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11515 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11516 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11517 presumably because the widths might not match.
11519 * window.c (size_window): Avoid needless test at loop start.
11521 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11523 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11525 2011-05-12 Drew Adams <drew.adams@oracle.com>
11527 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11529 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11531 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11532 `width' to `bar_area_x' and `bar_area_width', respectively.
11533 (x_scroll_run): Take account of fringe background extension.
11535 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11536 Rename local vars `left' and `width' to `bar_area_x' and
11537 `bar_area_width', respectively.
11538 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11539 background extension.
11541 2011-05-10 Jim Meyering <meyering@redhat.com>
11543 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11545 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11547 * image.c (Finit_image_library): Return t for built-in image types,
11548 like pbm and xbm. (Bug#8640)
11550 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11552 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11554 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11556 * w32console.c (Fset_screen_color): Doc fix.
11557 (Fget_screen_color): New function.
11558 (syms_of_ntterm): Defsubr it.
11560 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11561 unlink the temporary file if Fcall_process didn't create it in the
11563 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11564 child process will be redirected to a file specified with `:file'.
11565 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11566 cue to call_process_cleanup not to close that handle.
11568 2011-05-07 Ben Key <bkey76@gmail.com>
11570 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11571 one of two shell specific rules, either bootstrap-temacs-CMD or
11572 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11573 to the previous implementation of the bootstrap-temacs rule.
11574 The bootstrap-temacs-CMD rule is similar to the previous
11575 implementation of the bootstrap-temacs rule except that it
11576 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11579 These changes, along with some changes to nt/configure.bat,
11580 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11581 earlier fix to add support for --cflags and --ldflags options
11582 that include quotes so that it works whether make uses cmd or
11585 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11587 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11588 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11590 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11591 a string. Handle both cases.
11592 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11593 (Fdbus_register_method): Use Qinvalid_function.
11595 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11597 * makefile.w32-in: Update dependencies.
11598 (LISP_H): Add inttypes.h and stdin.h.
11599 (PROCESS_H): Add unistd.h.
11601 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11603 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11604 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11606 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11608 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11610 * term.c (vfatal): Remove stray call to va_end.
11611 It's not needed and the C Standard doesn't allow it here anyway.
11613 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11614 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11616 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11619 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11621 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11623 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11625 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11627 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11629 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11630 * charset.c (Fdefine_charset_internal): Don't initialize
11631 charset.code_space[15]. The value was garbage, on hosts with
11632 32-bit int (Bug#8600).
11634 * lread.c (read_integer): Be more consistent with string-to-number.
11635 Use string_to_number to do the actual conversion; this avoids
11636 rounding errors and fixes some other screwups. Without this fix,
11637 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11638 (digit_to_number): Move earlier, for benefit of read_integer.
11639 Return -1 if the digit is out of range for the base, -2 if it is
11640 not a digit in any supported base. (Bug#8602)
11642 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11644 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11645 to match comment at start of function. This also removes a
11646 GCC warning about overflow in a 32+64-bit port.
11648 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11650 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11651 Reported by Stefan Monnier in
11652 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11653 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11654 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11656 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11657 (EMACS_UINTPTR): Likewise, with uintptr_t.
11659 * lisp.h: Prefer 64-bit EMACS_INT if available.
11660 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11661 on 32-bit hosts that have 64-bit int, so that they can access
11663 However, temporarily disable this change unless the temporary
11664 symbol WIDE_EMACS_INT is defined.
11666 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11668 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11669 This removes an assumption that EMACS_INT and long are the same
11670 width as pointers. The assumption is true for Emacs porting targets
11671 now, but we want to make other targets possible.
11672 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11673 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11674 In the rest of the code, change types of integers that hold casted
11675 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11676 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11677 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11678 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11679 No need to cast type when ORing.
11680 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11681 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11682 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11683 assume EMACS_INT is the same width as char *.
11684 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11685 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11686 Remove no-longer-needed casts.
11687 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11688 (xg_tool_bar_help_callback, xg_make_tool_item):
11689 Use EMACS_INTPTR to hold an integer
11690 that will be cast to void *; this can avoid a GCC warning
11691 if EMACS_INT is not the same width as void *.
11692 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11693 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11694 (current_message_1, set_message_1):
11695 Use a local to convert to proper width without a cast.
11696 * xmenu.c (dialog_selection_callback): Likewise.
11698 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11699 Also, don't assume VALBITS / RAND_BITS is less than 5,
11700 and don't rely on undefined behavior when shifting a 1 left into
11702 * lisp.h (get_random): Change signature to match.
11704 * lread.c (hash_string): Use size_t, not int, for hash computation.
11705 Normally we prefer signed values; but hashing is special, because
11706 it's better to use unsigned division on hash table sizes so that
11707 the remainder is nonnegative. Also, size_t is the natural width
11708 for hashing into memory. The previous code used 'int', which doesn't
11709 retain enough info to hash well into very large tables.
11710 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11712 * dbusbind.c: Don't possibly lose pointer info when converting.
11713 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11714 Use XPNTR rather than XHASH, so that the high-order bits of
11715 the pointer aren't lost when converting through void *.
11717 * eval.c (Fautoload): Don't double-shift a pointer.
11719 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11721 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11723 * gnutls.c (DEF_GNUTLS_FN):
11724 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11726 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11728 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11731 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11733 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11734 New version that can reserve upto 2GB of heap space.
11736 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11738 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11740 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11742 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11743 `gnutls_certificate_set_x509_key_file'.
11745 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11747 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11748 Update dependencies.
11750 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11752 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11753 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11754 Remove unused parameter `fildes'.
11755 * process.c (read_process_output, send_process): Don't pass it.
11757 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11759 Fix previous change: the library cache is defined in w32.c.
11760 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11761 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11763 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11765 Implement dynamic loading of GnuTLS on Windows.
11767 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11768 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11769 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11772 * gnutls.c (Qgnutls_dll): Define.
11773 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11774 (gnutls_*): Declare function pointers.
11775 (init_gnutls_functions): New function to initialize function pointers.
11776 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11777 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11778 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):

11859 inttypes.h, as a gnulib replacement is used if it not available in
11862 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11864 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

11881 %llo or %llx format is passed. (Bug#8545)
11883 * window.c (window_scroll_line_based): Use a marker instead of
11884 simple variables to record original value of point. (Bug#7952)

11889 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11891 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11894 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11896 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11898 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11900 * keyboard.c (Qdelayed_warnings_hook): Define.
11901 (command_loop_1): Run `delayed-warnings-hook'
11902 if Vdelayed_warnings_list is non-nil.
11903 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11904 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.

11908 * doprnt.c (doprnt): Don't return value smaller than the buffer
11909 size if the message was truncated. (Bug#8545).
11911 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11913 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

11924 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11926 Improve `doprnt' and its usage. (Bug#8545)
11927 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11928 `format_end'. Remove support for %l as a conversion specifier.
11929 Don't use xrealloc. Improve diagnostics when the %l size modifier
11930 is used. Update the commentary.
11932 * eval.c (verror): Simplify calculation of size_t.
11934 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11937 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11939 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11942 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11944 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11945 This makes this file independent of the recent pseudovector change.
11947 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11949 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11951 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11952 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11953 Remove unused local.
11954 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11956 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11957 GCC 4.6.0 optimizes based on type-based alias analysis.
11958 For example, if b is of type struct buffer * and v of type struct
11959 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11960 != &v->size, and therefore "v->size = 1; b->size = 2; return
11961 v->size;" must therefore return 1. This assumption is incorrect
11962 for Emacs, since it type-puns struct Lisp_Vector * with many other
11963 types. To fix this problem, this patch adds a new type struct
11964 vectorlike_header that documents the constraints on layout of vectors
11965 and pseudovectors, and helps optimizing compilers not get fooled
11966 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11967 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11968 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11970 (XSETPVECTYPE): Rewrite in terms of new macro.
11971 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11972 This is a bit clearer, and further avoids the possibility of
11973 undesirable aliasing.
11974 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11975 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11976 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11977 since Lisp_Subr is a special case (no "next" field).
11978 (ASIZE): Now uses header.size rather than size.
11979 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11980 to avoid the hassle of writing XVECTOR (foo)->header.size.
11981 (struct vectorlike_header): New type.
11982 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11983 object, to help avoid aliasing.
11984 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11985 (SUBRP): Likewise, since Lisp_Subr is a special case.
11986 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11987 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11988 (struct Lisp_Hash_Table): Combine first two members into a single
11989 struct vectorlike_header member. All uses of "size" and "next" members
11990 changed to be "header.size" and "header.next".
11991 * buffer.h (struct buffer): Likewise.
11992 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11993 * frame.h (struct frame): Likewise.
11994 * process.h (struct Lisp_Process): Likewise.
11995 * termhooks.h (struct terminal): Likewise.
11996 * window.c (struct save_window_data, struct saved_window): Likewise.
11997 * window.h (struct window): Likewise.
11998 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11999 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12000 * buffer.c (init_buffer_once): Likewise.
12001 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12003 * process.c (Fformat_network_address): Use local var for size,
12006 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12008 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12009 * data.c (atof): Remove decl; no longer used or needed.
12010 (digit_to_number): Move to lread.c.
12011 (Fstring_to_number): Use new string_to_number function, to be
12012 consistent with how the Lisp reader treats infinities and NaNs.
12013 Do not assume that floating-point numbers represent EMACS_INT
12014 without losing information; this is not true on most 64-bit hosts.
12015 Avoid double-rounding errors, by insisting on integers when
12016 parsing non-base-10 numbers, as the documentation specifies.
12017 * lisp.h (string_to_number): New decl, replacing ...
12018 (isfloat_string): Remove.
12019 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12020 (read1): Do not accept +. and -. as integers; this
12021 appears to have been a coding error. Similarly, do not accept
12022 strings like +-1e0 as floating point numbers. Do not report
12023 overflow for integer overflows unless the base is not 10 which
12024 means we have no simple and reliable way to continue.
12025 Break out the floating-point parsing into a new
12026 function string_to_number, so that Fstring_to_number parses
12027 floating point numbers consistently with the Lisp reader.
12028 (digit_to_number): Move here from data.c. Make it static inline.
12029 (E_CHAR, EXP_INT): Remove, replacing with ...
12030 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12031 (string_to_number): New function, replacing isfloat_string.
12032 This function checks for valid syntax and produces the resulting
12033 Lisp float number too. Rework it so that string-to-number
12034 no longer mishandles examples like "1.0e+". Use strtoumax,
12035 so that overflow for non-base-10 numbers is reported only when
12036 there's no portable and simple way to convert to floating point.
12038 * textprop.c (set_text_properties_1): Rewrite for clarity,
12039 and to avoid GCC warning about integer overflow.
12041 * intervals.h (struct interval): Use EMACS_INT for members
12042 where EMACS_UINT might cause problems. See
12043 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12044 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12045 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12047 (offset_intervals): Tell GCC not to worry about length overflow
12048 when negating a negative length.
12050 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12051 (overrun_check_free): Likewise.
12053 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12054 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12057 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12058 (gnutls_make_error): Rename local to avoid shadowing.
12059 (gnutls_emacs_global_deinit): ifdef out; not used.
12060 (Fgnutls_boot): Use const for pointer to readonly storage.
12061 Comment out unused local. Fix pointer signedness problems.
12063 * lread.c (openp): Don't stuff size_t into an 'int'.
12064 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12065 about possible signed overflow.
12067 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12068 (GDK_KEY_g): Don't define if already defined.
12069 (xg_prepare_tooltip): Avoid pointer signedness problem.
12070 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12072 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12073 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12075 * xfns.c (Fx_window_property): Simplify a bit,
12076 to make a bit faster and to avoid GCC 4.6.0 warning.
12077 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12079 * fns.c (internal_equal): Don't assume size_t fits in int.
12081 * alloc.c (compact_small_strings): Tighten assertion a little.
12083 Replace pEd with more-general pI, and fix some printf arg casts.
12084 * lisp.h (pI): New macro, generalizing old pEd macro to other
12085 conversion specifiers. For example, use "...%"pI"d..." rather
12086 than "...%"pEd"...".
12087 (pEd): Remove. All uses replaced with similar uses of pI.
12088 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12089 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12090 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12091 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12092 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12093 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12094 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12096 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12097 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12098 * print.c (safe_debug_print, print_object): Likewise.
12099 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12101 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12102 avoiding the 0 flag, which is not portable.
12103 * process.c (Fmake_network_process): Use pI to avoid cast.
12104 * region-cache.c (pp_cache): Likewise.
12105 * xdisp.c (decode_mode_spec): Likewise.
12106 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12107 behavior on 64-bit hosts with printf arg.
12108 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12109 (x_stop_queuing_selection_requests): Likewise.
12110 (x_get_window_property): Don't truncate byte count to an 'int'
12113 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12114 here, since it parses constructs like leading '-' and spaces,
12115 which are not wanted; and it overflows with large numbers.
12116 Instead, simply match F[0-9]+, which is what is wanted anyway.
12118 * alloc.c: Remove unportable assumptions about struct layout.
12119 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12120 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12121 (allocate_vectorlike, make_pure_vector): Use the new macros,
12122 plus offsetof, to remove unportable assumptions about struct layout.
12123 These assumptions hold on all porting targets that I know of, but
12124 they are not guaranteed, they're easy to remove, and removing them
12125 makes further changes easier.
12127 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12128 This doesn't fix a bug but makes the code clearer.
12129 (string_overrun_cookie): Now const. Use initializers that
12130 don't formally overflow signed char, to avoid warnings.
12131 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12132 can cause Emacs to crash when string overrun checking is enabled.
12133 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12134 multiple of sizeof (EMACS_INT); it need not be, if
12135 alignof(EMACS_INT) < sizeof (EMACS_INT).
12136 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12138 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12140 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12142 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12144 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12145 supposed to be handshaking. (Bug#8556)
12146 Reported by Paul Eggert <eggert@cs.ucla.edu>.

12150 * lisp.h (Qdebug): List symbol.
12151 * eval.c (Qdebug): Restore global linkage.
12152 * keyboard.c (debug-on-event): New variable.
12153 (handle_user_signal): Break into debugger when debug-on-event
12154 matches the current signal symbol.
12156 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12158 * alloc.c (check_sblock, check_string_bytes)
12159 (check_string_free_list): Convert to standard C.
12161 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12163 * w32.c (emacs_gnutls_push): Fix typo.
12165 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12167 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12168 "cast to pointer from integer of different size".
12170 Improve doprnt and its use in verror. (Bug#8545)
12171 * doprnt.c (doprnt): Document the set of format control sequences
12172 supported by the function. Use SAFE_ALLOCA instead of always
12175 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12176 is one byte too soon. Don't use xrealloc; instead xfree and
12179 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12181 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12184 * gnutls.c: Renamed global_initialized to
12185 gnutls_global_initialized. Added internals for the
12186 :verify-hostname-error, :verify-error, and :verify-flags
12187 parameters of `gnutls-boot' and documented those parameters in the
12188 docstring. Start callback support.
12189 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12190 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12191 on error. Return error code.
12192 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12193 (emacs_gnutls_read): Likewise.
12194 (Fgnutls_boot): Return handshake error code.
12195 (emacs_gnutls_handle_error): New function.
12196 (wsaerror_to_errno): Likewise.

12199 (emacs_gnutls_push): Likewise.
12201 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.

12713 * font.c (font_close_object): Now static.
12714 * font.h (font_close_object): Remove.
12715 * fontset.c (FONTSET_OBJLIST): Remove.
12716 (free_realized_fontset) #if-0 the body, which does nothing.

12718 * fontset.h (face_suitable_for_char_p): Remove decl.
12719 * xfaces.c (face_at_string_position):
12720 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
12721 since 0 is always ASCII.
12723 * fns.c (weak_hash_tables): Now static.

12744 * editfns.c, lisp.h (get_operating_system_release): Remove.
12745 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
12746 worth the hassle of breaking this out.
12748 * xterm.c: Make symbols static if they're not exported.
12749 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

12861 * atimer.h (run_all_atimers): Remove; not exported.
12863 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12864 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12865 was inaccessible from Lisp.
12866 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12867 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12869 alloc.c: Import and export fewer symbols, and remove unused items.
12870 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12872 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12873 it's not optimized away by whole-program optimization.
12874 (message_enable_multibyte, free_misc): Remove.
12875 (catchlist, handlerlist, mark_backtrace):
12876 Declare only if BYTE_MARK_STACK.

12885 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12886 (mark_backtrace): Define only if BYTE_MARK_STACK.
12887 * xdisp.c (message_enable_multibyte): Now static.
12889 Declare Lisp_Object Q* variables to be 'static' if not exported.
12890 This makes it easier for human readers (and static analyzers)
12891 to see whether these variables are used from other modules.
12892 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12893 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

12903 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12905 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12907 Make Emacs functions such as Fatom 'static' by default.
12908 This makes it easier for human readers (and static analyzers)
12909 to see whether these functions can be called from other modules.
12910 DEFUN now defines a static function. To make the function external
12911 so that it can be used in other C modules, use the new macro DEFUE.
12912 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12913 (Finit_image_library):
12914 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12915 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12916 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12917 Remove decls, since these functions are now static.
12918 (Funintern, Fget_internal_run_time): New decls, since these functions
12919 were already external.
12921 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12922 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12928 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12929 Mark functions with DEFUE instead of DEFUN,
12930 if they are used in other modules.
12931 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12932 decls for now-static functions.
12933 * buffer.h (Fdelete_overlay): Remove decl.
12934 * callproc.c (Fgetenv_internal): Mark as internal.
12935 * composite.c (Fremove_list_of_text_properties): Remove decl.

12943 * image.c (Finit_image_library): New forward static decl.
12944 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

12946 (Fremove_list_of_text_properties): Remove decls.
12947 * keyboard.c (Fthis_command_keys): Remove decl.
12948 (Fcommand_execute): New forward static decl.

12964 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12966 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12969 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12971 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12972 when at ZV. (Bug#8487)
12974 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12976 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12978 * keyboard.c (parse_tool_bar_item): Likewise.
12979 * sound.c (sound_cleanup, alsa_close): Likewise.
12980 * termcap.c (tgetent): Likewise.

12982 * xsettings.c (read_and_apply_settings): Likewise.
12984 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12985 (overrun_check_free): Protoize.
12987 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12989 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12990 since callers should never pass a negative size.
12991 Change the signature to match that of plain 'read' and 'write'; see
12992 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12993 * lisp.h: Update prototypes of emacs_write and emacs_read.
12995 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12997 * xdisp.c (redisplay_window): Don't try to determine the character
12998 position of the scroll margin if the window start point w->startp
12999 is outside the buffer's accessible region. (Bug#8468)
13001 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13003 Fix write-region and its subroutines for buffers > 2GB.
13004 * fileio.c (a_write, e_write): Modify declaration of arguments and
13005 local variables to support buffers larger than 2GB.
13006 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13008 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13009 argument, local variables, and return value.
13011 * lisp.h: Update prototypes of emacs_write and emacs_read.
13013 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13015 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13017 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13019 Fix more problems found by GCC 4.6.0's static checks.
13021 * xdisp.c (vmessage): Use a better test for character truncation.
13023 * charset.c (load_charset_map): <, not <=, for optimization,
13024 and to avoid potential problems with integer overflow.
13025 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13026 * casetab.c (set_identity, shuffle): Likewise.
13027 * editfns.c (Fformat): Likewise.
13028 * syntax.c (skip_chars): Likewise.
13030 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13031 This also lets GCC 4.6.0 generate slightly better loop code.
13033 * callint.c (Fcall_interactively): <, not <=, for optimization.
13034 (Fcall_interactively): Count the number of arguments produced,
13035 not the number of arguments given. This is simpler and lets GCC
13036 4.6.0 generate slightly better code.
13038 * ftfont.c: Distingish more carefully between FcChar8 and char.
13039 The previous code passed unsigned char * to a functions like
13040 strlen and xstrcasecmp that expect char *, which does not
13041 conform to the C standard.
13042 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13043 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13044 char * when the C standard requires it.
13046 * keyboard.c (read_char): Remove unused var.
13048 * eval.c: Port to Windows vsnprintf (Bug#8435).
13049 Include <limits.h>.
13050 (SIZE_MAX): Define if the headers do not.
13051 (verror): Do not give up if vsnprintf returns a negative count.
13052 Instead, grow the buffer. This ports to Windows vsnprintf, which
13053 does not conform to C99. Problem reported by Eli Zaretskii.
13054 Also, simplify the allocation scheme, by avoiding the need for
13055 calling realloc, and removing the ALLOCATED variable.
13057 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13059 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13060 But keep the doprint source code for now, as we might revamp it
13061 and use it again (Bug#8435).
13062 * lisp.h (doprnt): Remove.
13063 * Makefile.in (base_obj): Remove doprnt.o.
13064 * deps.mk (doprnt.o): Remove.
13066 error: Print 32- and 64-bit integers portably (Bug#8435).
13067 Without this change, on typical 64-bit hosts error ("...%d...", N)
13068 was used to print both 32- and 64-bit integers N, which relied on
13069 undefined behavior.
13070 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13071 * lisp.h (error, verror): Mark as printf-like functions.
13072 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13073 Report overflow in size calculations when allocating printf buffer.
13074 Do not truncate output string at its first null byte.
13075 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13076 Truncate the output at a character boundary, since vsnprintf does not
13078 * charset.c (check_iso_charset_parameter): Convert internal
13079 character to string before calling 'error', since %c now has the
13081 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13082 overflow when computing char to be passed to 'error'. Do not
13083 pass Lisp_Object to 'error'; pass the integer instead.

13102 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13103 return ssize_t not "int", and use size_t as the buffer length.
13104 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13105 * gnutls.h: Update declarations.

13222 This avoids several warnings with gcc -Wstrict-overflow.
13223 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13224 directly, rather than having caller test rule sign. This avoids
13225 some unnecessary tests.
13226 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13227 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13228 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

13245 since the condition is always true at first.
13247 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13248 (interval_deletion_adjustment): Return unsigned value.
13251 * process.c (list_processes_1, create_pty, read_process_output):

13278 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13280 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13281 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13282 can always succeed if overflow has undefined behavior.
13284 * search.c (boyer_moore, wordify): Remove vars set but not used.
13285 (wordify): Omit three unnecessary tests.
13287 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

13315 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13316 that are set but not used.
13318 * xfns.c (make_invisible_cursor): Don't return garbage
13319 if XCreateBitmapFromData fails (Bug#8410).
13321 * xselect.c (x_get_local_selection, x_handle_property_notify):
13322 Remove vars that are set but not used.
13324 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

13346 that is set but not used.
13348 * print.c (print_object): Remove var that is set but not used.
13350 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13351 The gnulib version avoids calling malloc in the usual case,
13352 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13353 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13354 * filelock.c (current_lock_owner): Likewise.
13355 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13356 * sysdep.c: Include allocator.h, careadlinkat.h.
13357 (emacs_no_realloc_allocator): New static constant.
13358 (emacs_readlink): New function.
13359 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13360 ../lib/careadlinkat.h.
13362 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13364 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13365 first non-nil return value).

13381 (get_per_char_metric): Remove parameter `f', unused since
13382 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13426 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13427 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13428 (FletX, Flet): Obey lexical binding.
13429 (Fcommandp): Handle closures.
13430 (Feval): New `lexical' arg.
13431 (eval_sub): New function extracted from Feval. Use it almost
13432 everywhere where Feval was used. Look up vars in lexical env.
13434 (Ffunctionp): Move from subr.el.

13436 (apply_lambda): Remove `eval_flags'.
13437 (funcall_lambda): Handle closures and new byte-code-functions.
13438 (Fspecial_variable_p): New function.
13439 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

13442 * doc.c (Fdocumentation, store_function_docstring):
13443 * data.c (Finteractive_form): Handle closures.
13445 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13448 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13450 (exec_byte_code): New function extracted from Fbyte_code to handle new
13451 calling convention for byte-code-functions. Add new byte-codes.

13466 (redisplay_window): Even when falling back on "recentering",
13467 position point in the window according to scroll-conservatively,
13468 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13470 (try_scrolling): When point is above the window, allow searching
13471 as far as scroll_max, or one screenful, to compute vertical
13472 distance from PT to the scroll margin position. This prevents
13473 try_scrolling from unnecessarily failing when
13474 scroll-conservatively is set to a value slightly larger than the
13475 window height. Clean up the case of PT below the margin at bottom
13476 of window: scroll_max can no longer be INT_MAX. When aggressive
13477 scrolling is in use, don't let point enter the opposite scroll
13478 margin as result of the scroll.
13479 (syms_of_xdisp) <scroll-conservatively>: Document the
13480 threshold of 100 lines for never-recentering scrolling.

13489 (redisplay_internal): Remove parameter `preserve_echo_area',
13490 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13492 * indent.c (Fvertical_motion):
13493 * window.c (window_scroll_pixel_based, Frecenter):
13494 Don't pass `need_y_p' to `move_it_by_lines'.

13547 * keyboard.c (syms_of_keyboard): Use the same style as later
13548 in this function when indexing through an array. This also
13549 works around GCC bug 48267.
13551 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13553 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

13556 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13558 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13559 This avoids undefined behavior on integer overflow, and is a bit
13560 more convenient anyway since it is compared to a size_t variable.
13562 Variadic C functions now count arguments with size_t, not int.
13563 This avoids an unnecessary limitation on 64-bit machines, which
13564 caused (substring ...) to crash on large vectors (Bug#8344).
13565 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13566 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13567 All variadic functions and their callers changed accordingly.

13570 * editfns.c (general_insert_function): Likewise.
13571 * eval.c (struct backtrace.nargs, interactive_p)
13572 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13573 (funcall_lambda, mark_backtrace): Likewise.
13574 * fns.c (concat): Likewise.
13575 * frame.c (x_set_frame_parameters): Likewise.
13576 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13577 0 if not found, not -1. All callers changed.
13579 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13580 (stack_copy_size): Now size_t, not int.
13581 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

13590 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13591 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13602 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13603 don't set the hook to nil, but remove the offending function instead.
13604 (Qcommand_hook_internal): Remove, unused.
13605 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13606 Vcommand_hook_internal.
13608 * eval.c (enum run_hooks_condition): Remove.
13609 (funcall_nil, funcall_not): New functions.
13610 (run_hook_with_args): Call each function through a `funcall' argument.

13620 * print.c (strout): Remove parameter `multibyte', unused since
13621 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13623 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13624 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13625 All callers changed.
13627 * w32.c (_wsa_errlist): Use braces for struct initializers.

13637 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13638 All callers changed.
13640 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13642 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13653 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
13655 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

13671 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13673 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13675 * w32.c (read_unc_volume): Use parameter `henum', instead of
13676 global variable `wget_enum_handle'.
13678 * keymap.c (describe_vector): Remove parameters `indices' and
13679 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

13696 * process.c (wait_reading_process_output):
13697 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
13699 * insdel.c (adjust_markers_gap_motion):
13700 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

13785 * callint.c (Fcall_interactively):
13786 * buffer.c (Fkill_all_local_variables):
13787 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13789 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13790 unconditionally since it does the check itself.
13792 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13794 Fix more problems found by GCC 4.5.2's static checks.
13796 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13797 the first time through the loop, since we know p0 < p1 then.
13798 This also avoids a gcc -Wstrict-overflow warning.
13800 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13801 leading to a memory leak, possible in functions like
13802 load_charset_map_from_file that can allocate an unbounded number
13803 of objects (Bug#8318).
13805 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13806 that could (at least in theory) be that large.
13808 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13809 This is less likely to overflow, and avoids undefined behavior if
13810 overflow does occur. All callers changed. Use strtoul to scan
13811 for the unsigned long integer.
13812 (pint2hrstr): Simplify and tune code slightly.
13813 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13823 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13826 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13828 * process.c (Fmake_network_process): Use socklen_t, not int,
13829 where POSIX says socklen_t is required in portable programs.
13830 This fixes a porting bug on hosts like 64-bit HP-UX, where
13831 socklen_t is wider than int (Bug#8277).
13832 (Fmake_network_process, server_accept_connection):
13833 (wait_reading_process_output, read_process_output):
13836 * process.c: Rename or move locals to avoid shadowing.

13843 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13844 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13846 Make tparam.h and terminfo.c consistent.
13847 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13848 Include tparam.h instead, since it declares them.
13849 * cm.h (PC): Remove extern decl; tparam.h now does this.
13850 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13851 * terminfo.c: Include tparam.h, to check interfaces.
13852 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13853 (tparam): Adjust signature to match interface in tparam.h;
13854 this removes some undefined behavior. Check that outstring and len
13855 are zero, which they always are with Emacs.
13856 * tparam.h (PC, BC, UP): New extern decls.
13858 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13859 (xftfont_open): Rename locals to avoid shadowing.
13861 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13862 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13863 (OTF_TAG_SYM): Omit macro if not needed.
13864 (ftfont_list): Remove unused local.
13865 (get_adstyle_property, ftfont_pattern_entity):
13866 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13867 Rename locals to avoid shadowing.
13869 * xfont.c (xfont_list_family): Mark var as initialized.
13871 * xml.c (make_dom): Now static.
13873 * composite.c (composition_compute_stop_pos): Rename local to
13875 (composition_reseat_it): Remove unused locals.
13876 (find_automatic_composition, composition_adjust_point): Likewise.
13877 (composition_update_it): Mark var as initialized.
13878 (find_automatic_composition): Mark vars as initialized,
13879 with a FIXME (Bug#8290).
13881 character.h: Rename locals to avoid shadowing.
13882 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13883 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13884 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13885 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13886 to avoid shadowing.
13888 * textprop.c (property_change_between_p): Remove; unused.
13890 * intervals.c (interval_start_pos): Now static.
13892 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13894 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13895 Rename locals to avoid shadowing.
13897 * sound.c (wav_play, au_play, Fplay_sound_internal):
13898 Fix pointer signedness.
13899 (alsa_choose_format): Remove unused local var.
13900 (wav_play): Initialize a variable to 0, to prevent undefined
13901 behavior (Bug#8278).
13903 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13905 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13907 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13908 clobbering (Bug#8298).
13909 * sysdep.c (sys_subshell): Likewise.
13910 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13912 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13913 This should get cleaned up, so that child_setup has the
13914 same signature on all platforms.
13916 * callproc.c (call_process_cleanup): Now static.
13917 (relocate_fd): Rename locals to avoid shadowing.
13919 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13921 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13922 not to be necessary, and produces flickering.
13924 2011-03-20 Glenn Morris <rgm@gnu.org>
13926 * config.in: Remove file.
13928 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13930 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13931 are now in src/globals.h.
13932 (syms_of_minibuf): Remove spurious & from previous change.

13942 * xfaces.c (Fx_load_color_file):
13943 Read color file from absolute filename (bug#8250).

13949 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13951 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13958 (sigchld_handler): Now static.
13960 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13961 That way, the code declares only the vars that it needs.
13962 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13963 * s/cygwin.h (PTY_ITERATION): Likewise.
13964 * s/darwin.h (PTY_ITERATION): Likewise.

13967 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
13968 * process.c (allocate_pty): Don't declare stb unless it's needed.
13970 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
13971 (CONSTANTLIM): Remove; unused.
13972 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13973 Define only if needed.
13975 * unexelf.c (unexec): Name an expression,
13976 to avoid gcc -Wbad-function-cast warning.
13977 Use a different way to cause a compilation error if anyone uses
13978 n rather than nn, a way that does not involve shadowing.
13979 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13981 * deps.mk (unexalpha.o): Remove; unused.
13983 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13984 * unexec.h: New file.
13985 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13986 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):

14047 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14048 some of which prompt warnings from gcc -Wbad-function-cast.
14049 (Fformat_time_string, Fencode_time, Finsert_char):

14078 (Fmemory_limit): Cast sbrk's returned value to char *.
14080 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14083 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14085 Use functions, not macros, for up- and down-casing (Bug#8254).
14086 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14087 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14088 to use the following functions instead of these macros.
14089 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14090 EMACS_INT, since callers assume the returned value fits in int.
14091 (upcase1): Likewise, for UPCASE_TABLE.
14092 (uppercasep, lowercasep, upcase): New static inline functions.
14093 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14103 (regex_compile, re_match_2_internal): Mark locals as initialized.
14104 (RETALLOC_IF): Define only if needed.
14105 (WORDCHAR_P): Likewise. This one is never needed, but is used
14106 only in a comment talking about a compiler bug, so put inside
14107 the #if 0 of that comment.
14108 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14109 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14135 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14136 New macros, so that the caller can use some names other than
14137 gcpro1, gcpro2, etc.
14138 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14140 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14141 argument, for consistency with GCPRO2_VAR, etc: it is now the
14142 prefix of the variable, not the variable itself. All uses
14144 * dired.c (directory_files_internal, file_name_completion):
14145 Rename locals to avoid shadowing.
14147 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14148 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14149 dired.c's scmp function, had undefined behavior.
14150 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14151 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14152 * buffer.h: ... to here, because these macros use current_buffer,
14153 and the new implementation with inline functions needs to have
14154 current_buffer in scope now, rather than later when the macros
14156 (downcase, upcase1): New static inline functions.
14157 (DOWNCASE, UPCASE1): Reimplement using these functions.
14158 This avoids undefined behavior in expressions like
14159 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14160 from race conditions in accessing the global variables
14161 case_temp1 and case_temp2.
14162 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14163 * lisp.h (case_temp1, case_temp2): Remove their decls.
14164 * character.h (ASCII_CHAR_P): Move from here ...
14165 * lisp.h: ... to here, so that the inline functions mentioned
14166 above can use them.
14168 * dired.c (directory_files_internal_unwind): Now static.
14170 * fileio.c (file_name_as_directory, directory_file_name):

14173 (file_name_as_directory): Use const pointers when appropriate.
14174 (Fexpand_file_name): Likewise. In particular, newdir might
14175 point at constant storage, so make it a const pointer.
14176 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14177 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14179 (Fset_file_times, Finsert_file_contents, auto_save_error):

14184 to avoid shadowing.
14186 * marker.c (bytepos_to_charpos): Remove; unused.
14188 * lisp.h (verify_bytepos, count_markers): New decls,
14189 so that gcc does not warn that these functions aren't declared.
14191 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14192 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14193 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14194 (copy_text): Remove unused local var.
14196 * filelock.c (within_one_second): Now static.
14197 (lock_file_1): Rename local to avoid shadowing.
14199 * buffer.c (fix_overlays_before): Mark locals as initialized.
14200 (fix_start_end_in_overlays): Likewise. This function should be
14201 simplified by using pointers-to-pointers, but that's a different
14203 (switch_to_buffer_1): Now static.
14204 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14205 (report_overlay_modification): Rename locals to avoid shadowing.
14207 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14208 Fix pointer signedness issue.
14209 (sys_subshell): Mark local as volatile if checking for lint,
14210 to suppress a gcc -Wclobbered warning that does not seem to be right.
14211 (MAXPATHLEN): Define only if needed.
14213 * process.c (serial_open, serial_configure): Move decls from here ...
14214 * systty.h: ... to here, so that they can be checked.
14216 * fns.c (get_random, seed_random): Move extern decls from here ...
14217 * lisp.h: ... to here, so that they can be checked.
14219 * sysdep.c (reset_io): Now static.
14220 (wait_for_termination_signal): Remove; unused.
14222 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

14227 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14228 (describe_map_tree):
14229 Rename locals to avoid shadowing.
14231 * keyboard.c: Declare functions static if they are not used elsewhere.

14378 For example, without this patch (encode-time 0 0 0 1 1
14379 1152921504606846976) returns the obviously-bogus value (-948597
14380 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14381 reports time overflow. See
