418 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
419 emacs.c, as this is a more-suitable home. Had this been done earlier
420 the fix for 12036 would have avoided some of the problems noted in
421 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems

433 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
434 not be usable in #if. This simplifies things.
436 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
438 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
440 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

459 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
460 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):

1351 (menu_separator_name_p):

1354 * nsterm.m: Include <ftoastr.h>.
1356 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1357 Prefer snprintf to strncpy.
1358 * nsterm.m (ns_term_init):
1359 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1360 * nsterm.m (ns_term_init):
1361 Avoid the need for strncpy, by using build_string or
1362 make_unibyte_string directly. Use dtoastr, not snprintf.
1363 * process.c (Fmake_network_process): Diagnose service names that
1364 are too long, rather than silently truncating them or creating
1365 non-null-terminated names.

1382 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1383 where argument type is known to be a Lisp_Cons.

1395 Optimize pure C strings initialization.
1396 * lisp.h (make_pure_string): Fix prototype.
1397 (build_pure_c_string): New function, defined as static inline. This
1398 provides a better opportunity to optimize away calls to strlen when
1399 the function is called with compile-time constant argument.
1400 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1401 argument, adjust users accordingly. Use build_pure_c_string where
1403 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1404 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1405 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1407 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1409 Avoid calls to strlen in miscellaneous functions.
1410 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

1414 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1416 Avoid calls to strlen in path processing functions.
1417 * fileio.c (file_name_as_directory): Add comment. Change to add
1418 srclen argument and return the length of result. Adjust users
1420 (directory_file_name): Fix comment. Change to add srclen argument,
1421 swap 1st and 2nd arguments to obey the common convention. Adjust
1423 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1425 2012-07-10 Glenn Morris <rgm@gnu.org>
1427 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1428 Move PENDING_OUTPUT_COUNT definition to configure.
1430 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):

1432 * s/gnu.h (DATA_START): Move definitions to configure.
1434 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1435 We include usg5-4-common.h, which defines them both.
1437 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1438 O_RDONLY already includes it).
1440 Stop ns builds setting the EMACSLOADPATH environment variable.
1441 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1442 Now it does not set EMACSLOADPATH, just returns the load-path string.
1443 * nsterm.h: Update accordingly.
1444 * lread.c [HAVE_NS]: Include nsterm.h.
1445 (init_lread) [HAVE_NS]: Use ns_load_path.

1448 2012-07-09 Glenn Morris <rgm@gnu.org>
1450 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1451 since the included bsd-common.h does so.
1453 Stop ns builds setting the EMACSPATH environment variable.
1454 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1455 (ns_init_paths): Do not set EMACSPATH.
1456 * nsterm.h (ns_exec_path): Add it.
1457 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1460 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1462 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1464 * process.c (wait_reading_process_output): 'waitchannels' was unset
1465 when read_kbd || !NILP (wait_for_cell); fix this.
1467 Add GCC-style 'const' attribute to functions that can use it.
1468 * character.h (char_resolve_modifier_mask):
1469 * keyboard.h (make_ctrl_char):
1470 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1477 Declare the dummy function with ATTRIBUTE_CONST.
1478 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1479 Add decls with ATTRIBUTE_CONST.
1481 Minor improvements to make_formatted_string.
1482 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1483 where int is good enough, as vsprintf returns an int.
1484 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1486 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1488 Use make_formatted_string to avoid double length calculation.
1489 * lisp.h (make_formatted_string): New prototype.
1490 * alloc.c (make_formatted_string): New function.
1491 * buffer.c (Fgenerate_new_buffer_name): Use it.

1513 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1515 Move marker debugging code under MARKER_DEBUG.
1516 * marker.c (MARKER_DEBUG): Move marker debugging code under
1517 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1518 for bootstrap with --enable-checking (~3x slowdown reported
1519 by Juanma Barranquero <lekktu@gmail.com>).
1520 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1522 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1524 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1525 See <http://bugs.gnu.org/11825#29>.
1527 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1529 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1530 has no font, use the frame's font. (Bug#11813)
1531 (display_line): Add commentary about displaying truncation glyphs
1533 (produce_special_glyphs): Move here from term.c.
1535 * term.c (produce_special_glyphs): Move to xdisp.c.
1537 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1540 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1542 * xdisp.c (display_line): Avoid warning about implicit declaration
1545 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1547 * lisp.h: Remove empty conditional.
1549 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1551 * lread.c (load_path_check): Now static.
1553 Fix some minor --with-ns problems found by static checking.
1554 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1555 (x_set_font) [!HAVE_X_WINDOWS]:
1556 * image.c (xpm_load_image) [HAVE_NS]:
1557 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1558 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1559 Remove unused local.
1560 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1561 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1562 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1563 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1564 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1565 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1566 Fix pointer signedness problem.
1567 * xfaces.c (FRAME_X_FONT_TABLE):
1568 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1570 2012-07-07 Glenn Morris <rgm@gnu.org>
1572 * lread.c (load_path_check): New function, split from init_lread.
1573 (init_lread): Reorganize. Motivation:
1574 If EMACSLOADPATH is set, check/warn about that rather than the
1575 defaults, which we are not going to use. Hence we can remove
1576 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1577 Don't warn if site-lisp directories are missing.
1578 If not installed, start from a blank load-path, since
1579 PATH_LOADSEARCH refers to the eventual installation directories.
1581 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1583 Support truncation and continuation glyphs on GUI frames, when
1584 fringes are disabled. (Bug#11832)
1585 * xdisp.c (init_iterator): Get dimensions of truncation and
1586 continuation glyphs even if on GUI frames. Adjust
1587 it->last_visible_x on GUI frames when the left or right fringes,
1588 or both, are absent.
1589 (start_display, move_it_in_display_line_to): Handle the case of a
1590 GUI frame without a fringe to display continuation or truncation
1592 (insert_left_trunc_glyphs): Support GUI frames: make sure
1593 truncation glyphs overwrite enough glyphs from the current line to
1594 have sufficient space in pixels.
1595 (display_line): Support truncation and continuation glyphs on GUI
1596 frames. If some spare pixels are left on the line after inserting
1597 the truncation glyphs, fill that space with a stretch glyph of a
1598 suitably computed width.
1600 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1601 produce_glyphs, to support GUI sessions.
1603 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1605 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1607 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1609 Do not require float-time's arg to fit in time_t (Bug#11825).
1610 This works better on hosts where time_t is unsigned, and where
1611 float-time is applied to the (negative) difference between two times.
1612 * editfns.c (decode_time_components): Last arg is now double *,
1613 not int *, and means to store all the result as a double, without
1614 worrying about whether the seconds part fits in time_t.
1615 All callers changed.
1616 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1617 All callers changed.
1618 (Ffloat_time): Do not fail merely because the specified time falls
1619 outside of time_t range.
1621 2012-07-07 Glenn Morris <rgm@gnu.org>
1623 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1629 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1630 Update dependencies.
1632 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1634 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1636 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

1638 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1639 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1640 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1641 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1643 * xfont.c (compare_font_names): Redo to omit the need for casts.
1645 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1647 * xfns.c (Fx_change_window_property): Doc fix.
1648 * w32fns.c (Fx_change_window_property): Doc fix.
1650 * w32fns.c (Fx_window_property): Accept the same arguments as the
1651 X Windows version. Doc fix.
1652 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1654 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1655 Eli Zaretskii <eliz@gnu.org>
1657 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1658 Windows-specific code from nt/config.nt moved here.
1659 Obsolete settings removed.
1661 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1663 * process.c: Avoid unnecessary calls to gettime.
1664 (wait_reading_process_output): Don't get the time of day
1665 when gobbling data immediately and not waiting, as there's no need
1666 for it in that case. This removes a FIXME.
1668 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1670 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1671 is defined (Bug#11768).
1673 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1675 Fix marker debugging code.
1676 * marker.c (byte_char_debug_check): Do not perform the check
1677 if buffer is not multibyte.
1678 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1679 Call byte_char_debug_check with correct arguments.
1681 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1683 Compile marker debugging code only if ENABLE_CHECKING is defined.
1684 * marker.c (byte_char_debug_check, count_markers):
1685 Use only if ENABLE_CHECKING is defined.
1686 (byte_debug_flag): Remove.
1687 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1688 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1690 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1692 Avoid code repetition in marker-related functions.
1693 * marker.c (attach_marker): New function.
1694 (Fset_marker, set_marker_restricted, set_marker_both)
1695 (set_marker_restricted_both): Use it.
1696 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1697 Consistently rename charno to charpos.
1698 (marker_position): Add eassert.
1699 (marker_byte_position): Convert to eassert.

1718 * window.c (save_window_save): Likewise.
1720 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1722 Do not use Fdelete_overlay in delete_all_overlays
1723 to avoid redundant calls to unchain_overlay.
1724 * buffer.c (drop_overlay): New function.
1725 (delete_all_overlays, Fdelete_overlay): Use it.
1726 * minibuf.c (get_minibuffer): Fix comment.
1728 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1730 Port to OpenBSD 5.1 amd64.
1731 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1732 This is needed for OpenBSD, and should be harmless on all BSD systems.
1733 Also, include <sys/sysctl.h>, as it should be available on all
1734 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1735 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1736 use p_pid member, not kp_proc.pid.
1738 2012-07-06 Glenn Morris <rgm@gnu.org>
1740 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1742 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1744 More xmalloc and related cleanup.

1753 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1755 Omit needless casts involving void * pointers and allocation.
1756 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1757 as the former is more robust if P's type is changed.
1758 Prefer xzalloc to xmalloc + memset 0.
1759 Simplify malloc-or-realloc to realloc.
1760 Don't worry about xmalloc returning a null pointer.
1761 Prefer xstrdup to xmalloc + strcpy.
1762 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1764 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1765 alloca of a constant.
1767 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1769 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1770 hscroll is larger than the line width. Fixes long and futile
1771 looping inside extend_face_to_end_of_line (on a TTY) producing
1772 glyphs that are not needed and thrown away.
1774 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1776 * marker.c (set_marker_restricted_both): Simplify by using

1802 * xdisp.c (window_hscroll_limited): New function.
1803 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1804 coordinates when window's hscroll is set to insanely large
1807 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1809 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1870 * fileio.c (time_error_value): Check the right error number.
1871 Problem reported by Troels Nielsen in
1872 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1874 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1876 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1877 This should be fixed in a better way; see Eli Zaretskii in
1878 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1879 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1881 * fileio.c (time_error_value): Rename from special_mtime.
1882 The old name's problems were noted by Eli Zaretskii in
1883 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1885 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1886 This variable's comment says Emacs needs at least one GDB-visible
1887 symbol of type enum pvec_type, to work around GDB problems.
1888 The symbol's value doesn't matter.
1890 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1891 that causes compilation to fail on pre-C99 compilers.
1893 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1895 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1898 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1900 * buffer.c (init_buffer_once): Fix initialization of
1901 headers for buffer_defaults and buffer_local_symbols.
1902 Reported by Juanma Barranquero <lekktu@gmail.com>.
1904 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1906 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1907 * lisp.h (enum pvec_type): Use fewer bits.
1908 (PSEUDOVECTOR_SIZE_BITS): New constant.
1909 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1910 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1911 change in pvec_type.
1912 (PSEUDOVECTOR_TYPEP): New macro.
1913 (TYPED_PSEUDOVECTORP): Use it.
1914 * fns.c (internal_equal): Adapt code to extract pvectype.
1915 * emacs.c (gdb_pvec_type): Update type.
1916 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1917 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1918 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1919 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1920 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1921 abusing vector->header.next.nbytes.
1922 (live_vector_p): Use PVEC_TYPE.
1923 (mark_object): Adapt code to extract pvectype. Use switch.
1925 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1927 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1928 Tighten new eassert a bit.
1930 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1932 Fix compilation with --enable-gcc-warnings and -O1
1934 * doprnt.c (doprnt): Change type of tem to int, initialize
1935 to avoid compiler warning. Add eassert.
1936 * search.c (simple_search): Initialize match_byte to avoid
1937 compiler warning. Add eassert.
1939 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1941 Avoid weird behavior with large horizontal scrolls.
1942 Without this change, for example, large hscroll values would
1943 mess up Emacs's display on Fedora 15 x86, presumably due to
1944 overflows in int calculations in the display code.
1945 Also, if buffers had long lines, Emacs would freeze.
1946 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1947 (set_window_hscroll): New function, containing the old guts of
1948 Fset_window_hscroll. Return the clipped value.
1949 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1950 This avoids the need to check against PTRDIFF_MAX.
1952 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1954 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1956 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1958 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1960 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1961 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1962 since GCC 4.4.6 issues a bogus warning for them.
1964 Fix bugs in file timestamp newness comparisons.
1965 * fileio.c (Ffile_newer_than_file_p):
1966 * lread.c (Fload): Use full timestamp resolution of files,
1967 not just the 1-second resolution, so that files that are only
1968 slightly newer still count as newer.
1969 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1970 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1972 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1974 * fileio.c: Improve handling of file time marker. (Bug#11852)
1975 (special_mtime): New function.
1976 (Finsert_file_contents, Fverify_visited_file_modtime):
1977 Use it to set special mtime values consistently.
1979 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1981 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1982 marker for non-existing file. (Bug#11852)
1984 2012-07-03 Glenn Morris <rgm@gnu.org>
1986 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1987 and did not make it into globals.h).
1989 2012-07-03 Tom Tromey <tromey@redhat.com>
1991 * window.c (Fset_window_margins, Fset_window_fringes)
1992 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1993 * textprop.c (Fprevious_property_change): No longer static.

2025 * xterm.h: Remove EXFUN.
2027 2012-07-03 Glenn Morris <rgm@gnu.org>
2029 * lisp.h (Frandom): Make it visible to C.
2030 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2031 buffer for invisible buffers. (Bug#1229)
2033 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2035 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2036 values which aren't power of 2.
2037 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2038 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2041 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2043 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2045 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2047 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2049 * alloc.c (allocate_vector_block): Remove redundant
2050 calls to mallopt if DOUG_LEA_MALLOC is defined.
2051 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2052 avoid calls to mallopt if zero_vector is returned.
2054 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2056 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2057 is enabled, avoid dereferencing NULL current_sblock if
2060 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2062 Cleanup basic buffer management.
2063 * buffer.h (struct buffer): Change layout to use generic vector
2064 marking code. Fix some comments. Change type of 'clip_changed'
2065 to bitfield. Remove unused #ifndef old.
2066 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2067 (GET_OVERLAYS_AT): Fix indentation.
2068 (for_each_per_buffer_object_at): New macro.
2069 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2071 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2072 * alloc.c (allocate_buffer): Adjust to match new layout of
2073 struct buffer. Fix comment.
2074 (mark_overlay): New function.

2076 Lisp area of struct buffer.
2077 (mark_object): Use it. Adjust marking of misc objects
2078 and related comments.
2080 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2082 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2083 wrapper that is not needed because the wrapped code is a no-op (zero
2084 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2085 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2087 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2089 * alloc.c (mark_buffer): Simplify. Remove prototype.
2090 (mark_object): Add comment. Reorganize marking of vector-like
2091 objects. Use CHECK_LIVE for all vector-like objects except buffers
2092 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2093 redundant calls to mark_vectorlike for bool vectors.
2095 2012-06-30 Glenn Morris <rgm@gnu.org>
2097 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2099 * epaths.in (PATH_SITELOADSEARCH): New.
2100 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2101 This is rather than relying on --enable-locallisppath elements
2102 having "site-lisp" in their names. (Bug#10208#25, 11658)
2104 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2106 * w32proc.c (sys_select): Accept and ignore one more argument.
2108 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2110 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2111 (pselect) [!MS_DOS]: Redirect to sys_select.
2113 * sysdep.c: Don't include dos.h and dosfns.h.
2115 * process.c (sys_select):
2116 * msdos.c (sys_select): Accept one more argument and ignore it.
2118 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2119 adapt data types and code to that.
2122 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2123 which clashes with the gnulib function of the same name.
2125 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2127 * font.c (font_style_to_value, font_style_symbolic)
2128 (font_prop_validate_style): Add type checks for values in
2131 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2133 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2136 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2138 * xdisp.c (try_window_id): Undo last change.
2140 * w32.c (getwd): Adjust commentary about startup_dir.
2141 (init_environment): Always call sys_access, even in non-MSVC
2142 builds. Don't chdir to the directory of the Emacs executable.
2143 This undoes code from 1997 which was justified by the need to
2144 "avoid conflicts when removing and renaming directories". But its
2145 downside was that every relative file name was being interpreted
2146 relative to the directory of the Emacs executable, which can never
2147 be TRT. In particular, it broke sys_access when called with
2148 relative file names.
2149 (sys_access): Map GetLastError to errno.
2151 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2153 * window.h (struct window): Change type of 'fringes_outside_margins'
2154 to bitfield. Fix comment. Adjust users accordingly.
2155 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2157 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2160 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2162 * gnutls.c (emacs_gnutls_handshake):
2163 Add QUIT to make the loop interruptible.
2165 2012-06-29 Glenn Morris <rgm@gnu.org>
2167 * charset.c (init_charset): Make lack of etc/charsets fatal.
2169 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2171 * editfns.c (region_limit): Fix type mismatch.
2173 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2175 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2176 undefined. Convert from xassert to eassert.
2177 * nsmenu.m: Convert from xassert to eassert.
2178 * nsterm.m: Likewise.
2180 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2182 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2184 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2186 Avoid integer overflow on scroll-left and scroll-right.
2187 * window.c (HSCROLL_MAX): New macro.
2188 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2189 overflow when requested scroll falls outside ptrdiff_t range.
2191 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2193 * window.h (struct window): Change type of 'hscroll',
2194 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2195 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2196 Adjust users accordingly.
2197 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2198 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2199 from EMACS_INT to ptrdiff_t.
2200 (make_window): Omit redundant initialization.
2202 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2204 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2206 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2208 * window.h (struct window): Change type of 'use_time' and
2209 'sequence_number' from Lisp_Object to int.
2210 * frame.c (make_frame): Adjust users accordingly.
2211 * print.c (print_object): Likewise.
2212 * window.c (select_window, Fwindow_use_time, make_parent_window)
2213 (make_window): Likewise.
2215 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2218 enabled with --enable-checking=[all,glyphs] configure option.
2219 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2220 adjust comments accordingly.

2269 * alloc.c (allocate_string_data): Remove dead code.
2270 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2271 avoid GCC warning about unused macro.
2273 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2275 * alloc.c (allocate_string): Omit intervals initialization.
2276 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2277 as in make_pure_string and make_pure_c_string.
2279 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2281 * alloc.c (allocate_string): Fix last change.
2283 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2285 * alloc.c (allocate_string): Remove two redundant calls
2286 to memset, add explicit initialization where appropriate.

2311 _stricmp and _strnicmp.
2312 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
2314 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
2316 * alloc.c (allocate_window): Zero out non-Lisp part of newly
2318 (allocate_process): Likewise for new process.
2319 (allocate_terminal): Change to use offsetof.
2320 (allocate_frame): Likewise.
2321 * frame.c (make_frame): Omit redundant initialization.
2322 * window.c (make_parent_window): Use memset.

2333 * alloc.c: Remove build_string.
2334 * lisp.h: Define build_string as static inline. This provides
2335 a better opportunity to optimize away calls to strlen when the
2336 function is called with compile-time constant argument.
2337 * image.c (imagemagick_error): Convert to build_string.
2338 * w32proc.c (sys_spawnve): Likewise.
2339 * xterm.c (x_term_init): Likewise.
2341 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2343 Use sprintf return value instead of invoking strlen on result.
2344 In the old days this wasn't portable, since some sprintf
2345 implementations returned char *. But they died out years ago and
2346 Emacs already assumes sprintf returns int.
2347 Similarly for float_to_string.
2348 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2360 * term.c (produce_glyphless_glyph):
2361 Use sprintf result rather than recomputing it.

2462 * keyboard.c (kbd_buffer_get_event):
2463 * process.c (Faccept_process_output):
2464 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2465 This improves on the previous patch, which introduced a bug
2466 when time_t is unsigned and as wide as intmax_t.
2467 See <http://bugs.gnu.org/9000#51>.
2469 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2486 Privately reported by Herbert J. Skuhra.
2487 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

2498 language ID in the event parameters.
2500 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2524 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2525 Privately reported by Herbert J. Skuhra.

2529 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2530 Don't assume EMACS_TIME and struct timeval are the same type.
2532 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2534 Support higher-resolution time stamps (Bug#9000).
2535 The time stamps are only nanosecond-resolution at the C level,
2536 since that's the best that any real-world system supports now.
2537 But they are picosecond-resolution at the Lisp level, as that's
2538 easy, and leaves room for future OS improvements.
2540 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2543 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2544 Don't get current time unless it's needed.
2546 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2547 now provides it if it's absent.
2548 (start_atimer): Port to higher-res time stamps.
2549 Check for time stamp overflow. Don't get current time more
2550 often than is needed.
2552 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2553 Include systime.h, not time.h.
2554 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2556 * dired.c: Include stat-time.h.
2557 (Ffile-attributes): File times now have higher resolution.
2559 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2560 (struct image): Timestamp now has higher resolution.
2562 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2563 has at least microseconds now. All uses removed.
2564 (update_frame, update_single_window, update_window, update_frame_1)
2565 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2567 * editfns.c (time_overflow): Now extern.
2568 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2569 (float-time, Fformat_time_string, Fcurrent_time_string)
2570 (Fcurrent_time_zone): Accept and generate higher-resolution
2572 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2573 (decode_time_components, lisp_seconds_argument): New functions.
2574 (make_time): Now static.
2575 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2576 Report an error if the time is invalid, rather than having the caller
2579 * fileio.c: Include <stat-time.h>
2580 (Fcopy_file): Copy higher-resolution time stamps.
2581 Prefer to set the time stamp via a file descriptor if that works.
2582 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2583 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2584 (Fvisited_file_modtime, Fset_visited_file_modtime):
2585 Support higher-resolution time stamps.
2587 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2589 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2591 * image.c (prepare_image_for_display, clear_image_cache)
2592 (lookup_image): Port to higer-resolution time stamps.
2594 * keyboard.c (start_polling, bind_polling_period):
2595 Check for time stamp overflow.
2596 (read_char, kbd_buffer_get_event, timer_start_idle)
2597 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2598 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2599 Port to higher-resolution time stamps. Do not assume time_t is signed.
2600 (decode_timer): New function. Timers are now vectors of length 9,
2601 not 8, to accommodate the picosecond component.
2602 (timer_check_2): Use it.
2604 * nsterm.m (select_timeout, timeval_subtract): Remove.
2605 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2606 as they're a bit more accurate and handle overflow better.
2607 (ns_select): Change prototype to be compatible with pselect.
2608 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2609 * nsterm.h (ns_select): Adjust prototype.
2611 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2612 us-resolution time stamps.
2613 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2615 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2617 * lisp.h (time_overflow): New decl.
2618 (wait_reading_process_output): First arg is now intmax_t, not int,
2619 to accommodate larger waits.
2621 * process.h (struct Lisp_Process.read_output_delay):
2622 Now counts nanoseconds, not microseconds.
2623 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2625 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2626 (wait_reading_process_output):
2627 Port to ns-resolution time stamps.
2628 (Faccept_process_output, wait_reading_process_output):
2629 Check for time stamp overflow. Do not assume time_t is signed.
2630 (select_wrapper): Remove; we now use pselect.
2631 (Fprocess_attributes): Now generates ns-resolution time stamps.
2633 * sysdep.c: Include utimens.h. Don't include utime.h
2634 or worry about struct utimbuf; gnulib does that for us now.
2635 (gettimeofday): Remove; gnulib provides a substitute.
2636 (make_timeval): New function.
2637 (set_file_times): Now sets ns-resolution time stamps.
2638 New arg FD; all uses changed.
2639 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2640 (system_process_attributes):
2641 Now returns ns-resolution time stamp. All uses changed.
2642 Check for time stamp overflow.
2644 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2645 provides a substitute now.
2647 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2648 since it guarantees struct timespec.
2649 (EMACS_TIME): Now struct timespec, so that we can support
2650 ns-resolution time stamps.
2651 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2652 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2653 (EMACS_USECS): Remove.
2654 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2655 so multiply the arg by 1000 before storing it.
2656 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2658 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2659 Port to ns-resolution time stamps.
2660 (EMACS_TIME_NEG_P): Remove; replaced by....
2661 (EMACS_TIME_SIGN): New macro.
2662 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2663 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2664 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2665 (make_timeval, make_lisp_time, decode_time_components): New decls.
2666 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2667 that it mishandled time_t overflow. You can't compare by subtracting!
2668 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2669 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2671 * term.c: Include <sys/time.h>.
2672 (timeval_to_Time): New function, for proper overflow wraparound.
2673 (term_mouse_position, term_mouse_click): Use it.

2677 (Fprimitive_undo): Use them when restoring time stamps.
2679 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2680 (w32_get_internal_run_time):
2681 Port to higher-resolution Emacs time stamps.
2682 (ltime): Now accepts single 64-bit integer, as that's more convenient
2685 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2687 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2688 for compatibility with pselect. Support ns-resolution time stamps.
2690 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2692 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2693 Check for time stamp overflow, and support ns-resolution time stamps.
2695 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2696 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2697 (timeval_subtract): Remove; no longer needed.
2698 (XTflash, XTring_bell, x_wait_for_event):
2699 Port to ns-resolution time stamps. Don't assume time_t is signed.
2701 2012-06-22 Chong Yidong <cyd@gnu.org>
2703 * xdisp.c (x_consider_frame_title): Revert last change.
2705 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2707 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2708 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2709 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2710 staticidx goes up to 1597 out of 1600 = 0x640.)
2712 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2714 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2715 Otherwise, the umask might be mistakenly 0 while handling input signals.
2717 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2719 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

2724 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
2725 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2726 access to `contents' member of Lisp_Vector objects with AREF and ASET
2729 2012-06-19 Chong Yidong <cyd@gnu.org>
2731 * frame.c (delete_frame): When selecting a frame on a different
2732 text terminal, do not alter the terminal's top-frame.

2735 frame's selected window and its terminal's top-frame.
2736 (unwind_format_mode_line): Restore them.
2737 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2739 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2740 since tty frames can be explicitly named.
2741 (prepare_menu_bars): Likewise.
2743 * term.c (Ftty_top_frame): New function.
2745 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2747 Port byte-code-meter to modern targets.
2748 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2749 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2750 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2751 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2752 (METER_1, METER_2): Simplify.
2754 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2756 * data.c (Fdefalias): Return `symbol' (bug#11686).
2758 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2760 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2761 gets killed during executing of this function (Bug#11665).
2762 Try to always return Qt when the buffer has been actually killed.
2763 (Vkill_buffer_query_functions): In doc-string say that functions
2764 run by this hook should not change the current buffer.
2766 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2768 Fix recently-introduced process.c problems found by static checking.
2769 * process.c (write_queue_push, write_queue_pop, send_process):
2770 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
2771 (write_queue_pop): Fix pointer signedness problem.
2772 (send_process): Remove unused local.
2774 2012-06-17 Chong Yidong <cyd@gnu.org>

2777 frames that are not on top.
2779 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
2781 * process.c (make_process): Initialize write_queue.
2782 (write_queue_push, write_queue_pop): New functions.
2783 (send_process): Use them to maintain correct ordering of process
2786 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2788 * lisp.h (eassert): Assume C89 or later.
2789 This removes the need for CHECK.
2790 (CHECK): Remove. Its comments about always evaluating its
2791 argument were confusing, as 'eassert' typically does not evaluate
2794 * coding.c (produce_chars): Use ptrdiff_t, not int.
2796 * xterm.c (x_draw_underwave): Check for integer overflow.
2797 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
2799 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
2801 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

2982 code works fine either way, and efficiency is not a concern here,
2983 as the union type is for debugging, not for production.
2984 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2985 Use an inline function on all platforms when using the union type,
2986 since this is simpler and 'static inline' can be used portably

3130 * doprnt.c (doprnt): Truncate multibyte char correctly.
3131 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3132 would mishandle a string argument "Xc" if X was a multibyte

3208 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3209 fields from Lisp_Object to bitfield. Adjust users accordingly.

3217 and 'double' in a couple of places.
3219 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3221 * xdisp.c (handle_stop): Detect whether we have overlay strings
3222 loaded by testing it->current.overlay_string_index to be
3223 non-negative, instead of checking whether n_overlay_strings is
3224 positive. (Bug#11587)

3234 * search.c (search_buffer): Remove calls to

3236 maybe_unify_char, which was the cause of relocation of buffer text
3239 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3241 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3242 for the duration of call to load_charset, to avoid problems with
3243 callers of maybe_unify_char that access buffer text through C
3246 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3247 decrement the inhibition flag, instead of just setting or
3250 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>

3253 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

3257 (gray_bitmap_bits): Remove; no longer needed.

3299 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3301 Do not create empty overlays with the evaporate property (Bug#9642).
3302 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3303 Bug#9642, but explicitly check that the buffer the overlay would
3304 be moved to is live and rearrange lines to make sure that errors
3305 will not put the overlay in an inconsistent state.
3306 (Fdelete_overlay): Cosmetics.
3308 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3310 * w32term.c (my_bring_window_to_top): New function.
3311 (x_raise_frame): Use handle returned by DeferWindowPos, which
3312 could be different from the original one.

3316 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3317 by calling BringWindowToTop.
3319 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3320 (WM_EMACS_END): Increase by one.
3322 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3324 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3325 This avoids undefined behavior that might cause the eassert
3326 to not catch an out-of-range value.
3328 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3330 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3331 Update dependencies.

3340 when referring to sectname field in printf format.
3342 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3344 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3345 Only r_alloc_inhibit_buffer_relocation needed to be added;
3346 the others were already declared.
3348 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3349 before checking whether it's out of range. Put the check inside
3351 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3353 2012-05-27 Ken Brown <kbrown@cornell.edu>
3355 * callproc.c (Fcall_process): Restore a line that was accidentally
3356 commented out in the 2011-02-13 change (bug#11547).
3358 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3360 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3361 defined on ralloc.c.
3363 * buffer.c [REL_ALLOC]: Remove prototypes of
3364 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3365 they are now on lisp.h.
3367 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3369 * search.c (search_buffer): Use it to inhibit relocation of buffer
3370 text while re_search_2 is doing its job, because re_search_2 is
3371 passed C pointers to buffer text. (Bug#11519)
3373 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3376 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3377 state after an additional call to move_it_in_display_line_to, keep
3378 the values of it->max_ascent and it->max_descent found for the
3380 (pos_visible_p): Revert the comparison against bottom_y to what it
3381 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3384 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3386 Fix coding-related core dumps with gcc -ftrapv.
3387 The code was computing A - B, where A and B are pointers, and B is
3388 random garbage. This can lead to core dumps on platforms that
3389 have special pointer registers, and it also leads to core dumps on
3390 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3391 A - B only when B is initialized properly.
3392 * coding.c (coding_set_source, coding_set_destination): Return void.
3393 (coding_change_source, coding_change_destinations): New functions,
3394 with the old behaviors of coding_set_source and coding_set_destination.
3395 All callers that need an offset changed to use these new functions.
3397 2012-05-26 Glenn Morris <rgm@gnu.org>
3399 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3401 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3403 Extend mouse support on W32 text-mode console.
3404 * xdisp.c (draw_row_with_mouse_face):
3405 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3407 * w32console.c: Include window.h.
3408 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3410 (initialize_w32_display): Initialize mouse-highlight data.
3412 * w32inevt.c: Include termchar.h and window.h.
3413 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3414 moves, call note_mouse_highlight. If help_echo changed, call
3415 gen_help_event to produce help-echo message in the echo area.
3416 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3419 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3421 * lread.c (read1): Simplify slightly to avoid an overflow warning
3422 with GCC 4.7.0 on x86-64.
3424 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3426 * bidi.c (bidi_mirror_char): Revert last change: an int is
3427 definitely wide enough here.
3429 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3431 Fix integer width and related bugs (Bug#9874).

3439 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3441 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3442 (allocate_pseudovector):
3443 Use int, not EMACS_INT, where int is wide enough.
3444 (inhibit_garbage_collection, Fgarbage_collect):
3445 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3446 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3447 int might not be wide enough.
3448 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3451 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3452 (bidi_level_of_next_char, bidi_move_to_visually_next):
3453 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3454 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3455 (Fkill_buffer, Fset_buffer_major_mode)

3461 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3462 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3463 (Foverlay_recenter, last_overlay_modification_hooks_used)
3464 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3465 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3466 (validate_region): Omit unnecessary test for b <= e,
3467 since that's guaranteed by the previous test.
3468 (adjust_overlays_for_delete): Avoid pos + length overflow.
3469 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3470 (report_overlay_modification):
3471 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3472 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3473 Omit pointer cast, which isn't needed anyway, and doesn't work
3474 after the EMACS_INT -> ptrdiff_t change.
3475 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3476 * buffer.h: Adjust decls to match defn changes elsewhere.

3481 not int, to avoid needless 32-bit limit on 64-bit hosts.
3482 (exec_byte_code): Use tighter memory-full test, one that checks
3483 for alloca overflow. Don't compute the address of the object just
3484 before an array, as that's not portable. Use EMACS_INT, not
3485 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3486 * callint.c (Fcall_interactively):
3487 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3488 * callproc.c (call_process_kill, Fcall_process):

3498 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3499 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3500 (casify_object): Avoid integer overflow when overallocating buffer.
3501 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3502 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3503 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3504 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3505 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3506 integers are now checked earlier. All uses replaced with XINT.
3508 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3509 For CCL_MapSingle, check that content and value are in int range.
3510 (ccl_driver, Fregister_code_conversion_map):
3511 Check that Vcode_version_map_vector is a vector.
3512 (resolve_symbol_ccl_program): Check that vector header is in range.
3513 Always copy the vector, so that we can check its contents reliably
3514 now rather than having to recheck each instruction as it's being
3515 executed. Check that vector words fit in 'int'.
3516 (ccl_get_compiled_code, Fregister_ccl_program)
3517 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3518 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3519 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3520 contents are in range.
3521 (Fccl_execute_on_string): Check that status is in range.
3522 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3523 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3524 Accept and return EMACS_INT, not int, because callers can pass values
3526 (c_string_width, strwidth, lisp_string_width, chars_in_text)

3530 (string_escape_byte8, Fget_byte):
3531 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3532 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3533 avoid mishandling large integers.
3534 * character.h: Adjust decls to match defn changes elsewhere.

3543 (Fdefine_charset_internal): Check ranges here, more carefully.
3544 Don't rely on undefined behavior with signed left shift overflow.
3545 Don't assume unsigned int fits into fixnum, or that fixnum fits
3546 into unsigned int. Don't require max_code to be a valid fixnum;
3547 that's not true for gb10830 4-byte on a 32-bit host. Allow
3548 invalid_code to be a cons, for the same reason. Require code_offset
3549 to be a character. Avoid int overflow if max_char is close
3551 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3552 this is intended anyway and avoids some undefined behavior.
3553 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3554 INDEX_TO_CODE_POINT, as that's what it expects.
3555 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3556 * charset.h (DECODE_CHAR): Return int, not unsigned;
3557 this is what was intended anyway, and it avoids undefined behavior.
3558 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3559 integer-overflow issues.
3560 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3561 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3562 where the argument is EMACS_INT, and this behavior is not intended.
3563 * chartab.c (Fmake_char_table, Fset_char_table_range)
3564 (uniprop_get_decoder, uniprop_get_encoder):
3565 Don't assume fixnum fits in int.
3566 * cmds.c (move_point): New function, that does the gist of
3567 Fforward_char and Fbackward_char, but does so while checking
3568 for integer overflow more accurately.
3569 (Fforward_char, Fbackward_char): Use it.
3570 (Fforward_line, Fend_of_line, internal_self_insert)
3571 (internal_self_insert):
3572 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3573 Fix a FIXME, by checking for integer overflow when calculating
3574 target_clm and actual_clm.

3609 Don't access memory outside of the args array.
3610 (Fdefine_coding_system_internal): Check for charset-id overflow.

4370 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4371 already have overlays loaded.
4372 (handle_single_display_spec): Before returning without displaying
4373 fringe bitmap, synchronize the bidi iterator with the main display
4374 iterator, by calling iterate_out_of_display_property.
4375 (iterate_out_of_display_property): Detect buffer iteration by
4376 testing that it->string is a Lisp string.
4377 (get_next_display_element): When the current object is exhausted,
4378 and there's something on it->stack, call set_iterator_to_next to

4381 proceed to consider_string_end without incrementing string
4382 position. Don't increment display vector index past the end of
4383 the display vector. (Bug#11417)
4384 (pos_visible_p): Don't report a position visible when move_it_to
4385 stopped at the last line of window, which happens to be scanned
4386 backwards by the bidi iteration. (Bug#11464)
4388 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4390 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4391 and right-margin display specs even if the spec is invalid or we
4392 are on a TTY, and thus unable to display on the fringes.
4393 That's because the text with the property will not be displayed anyway,
4394 so we need to signal to the caller that this is a "replacing"
4395 display spec. This fixes display when the spec is invalid or we
4398 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4400 * unexaix.c (make_hdr): Fix typo in prototype.

4419 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4421 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4423 Remove unused function hourglass_started.
4424 * dispextern.h (hourglass_started):
4425 * w32fns.c (hourglass_started):
4426 * xdisp.c (hourglass_started): Remove.
4428 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4430 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4431 Update dependencies.
4433 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4435 * xgselect.c (xg_select): Put maxfds+1 into a var.
4436 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4438 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4440 2012-05-10 Dave Abrahams <dave@boostpro.com>
4442 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4443 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4445 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4447 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4448 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4449 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4450 Initialize xd_registered_buses.
4452 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4454 Untag more efficiently if USE_LSB_TAG.
4455 This is based on a proposal by YAMAMOTO Mitsuharu in
4456 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4457 For an admittedly artificial (nth 8000 longlist) benchmark on
4458 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4459 Emacs's overall text size by 1%.
4460 * lisp.h (XUNTAG): New macro.
4461 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4462 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4463 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4464 * eval.c (Fautoload):
4465 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4466 * frame.h (XFRAME): Use XUNTAG.
4468 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4469 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4470 Remove unportable assumptions about print widths of types like
4472 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4473 intptr_t when converting between pointer and integer, to avoid GCC
4474 warnings about wrong width.
4476 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4478 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4479 stack for each reader_thread, instead of defaulting to 8MB
4480 determined by the linker. This avoids failures in creating
4481 subprocesses on Windows 7, see the discussion in this thread:
4482 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4484 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4486 Fix up display of the *Minibuf-0* buffer in the mini window.
4487 * keyboard.c (read_char): Don't clear the echo area if there's no
4489 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4490 contents of *Minibuf-0*) if there's no message displayed in its stead.
4492 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4494 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4497 2012-05-06 Chong Yidong <cyd@gnu.org>
4499 * lisp.mk (lisp): Update.
4501 2012-05-05 Jim Meyering <meyering@redhat.com>
4503 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4505 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4507 * data.c (PUT_ERROR): New macro.
4508 (syms_of_data): Use it. Add new error type `user-error'.
4509 * undo.c (user_error): New function.
4510 (Fprimitive_undo): Use it.
4511 * print.c (print_error_message): Adjust print style for `user-error'.
4512 * keyboard.c (user_error): New function.
4513 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4515 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4517 Do not limit current-time-string to years 1000..9999.
4518 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4519 (Fcurrent_time_string): Support any year that is supported by the
4520 underlying localtime representation. Don't use asctime, as it
4521 has undefined behavior for years outside the range -999..9999.
4523 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4525 Fix race conditions involving setenv, gmtime, localtime, asctime.
4526 Without this fix, interrupts could mess up code that uses these
4527 nonreentrant functions, since setting TZ invalidates existing
4528 tm_zone or tzname values, and since most of these functions return
4529 pointers to static storage.
4530 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4531 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4532 Grow the critical sections to include not just invoking
4533 localtime/gmtime, but also accessing these functions' results
4534 including their tm_zone values if any, and any related TZ setting.
4535 (format_time_string): Last arg is now struct tm *, not struct tm **,
4536 so that the struct tm is saved in the critical section.
4537 All callers changed. Simplify allocation of initial buffer, partly
4538 motivated by the fact that memory allocation needs to be outside
4539 the critical section.
4541 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4543 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4544 with RESET_INTERVAL.
4546 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4547 Remove duplicated buffer name initialization.
4549 2012-05-02 Jim Meyering <jim@meyering.net>
4551 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4553 * xfns.c (x_window): Use xstrdup (Bug#11375).
4555 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4557 * xdisp.c (pos_visible_p): If already at a newline from the
4558 display string before the 'while' loop, don't walk back the glyphs
4559 from it3.glyph_row. Solves assertion violation when the display
4560 string begins with a newline (egg.el). (Bug#11367)
4562 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4564 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4567 2012-05-01 Glenn Morris <rgm@gnu.org>
4569 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4570 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4571 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4572 All were removed before 23.1.
4574 * dispnew.c: Remove HAVE_LIBNCURSES test;
4575 it is always true on relevant platforms.
4577 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4578 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4580 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4582 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4584 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4585 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4588 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4590 Do not avoid creating empty evaporating overlays (Bug#9642).
4591 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4592 That is, do not delete an evaporating overlay if it becomes
4593 empty after its bounds are adjusted to fit within its buffer.
4594 This fix caused other problems, and I'm reverting it until we get
4595 to the bottom of them.
4597 2012-04-27 Chong Yidong <cyd@gnu.org>
4599 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4601 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4603 * xdisp.c (pos_visible_p): If the window start position is beyond
4604 ZV, start the display from buffer beginning. Prevents assertion
4605 violation in init_iterator when the minibuffer window is scrolled
4608 * window.c (window_scroll_pixel_based): Likewise.
4610 2012-04-27 Chong Yidong <cyd@gnu.org>
4612 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4614 2012-04-27 Glenn Morris <rgm@gnu.org>
4616 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4617 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4619 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4621 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4622 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4624 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4626 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4627 display element, check also the underlying string or buffer
4628 character. (Bug#11341)
4630 * w32menu.c: Include w32heap.h.
4631 (add_menu_item): If the call to AppendMenuW (via
4632 unicode_append_menu) fails, disable Unicode menus only if we are
4633 running on Windows 9X/Me.
4635 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4637 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4638 (xgetint): Add missing shift for LSB tags.
4640 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4642 * keyboard.c (read_char): Don't wipe echo area for select window
4643 events: These might get delayed via `mouse-autoselect-window'
4646 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4648 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4649 manipulation of :loaded-from data.
4651 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4653 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4654 now a cons (bug#11311).
4656 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4658 Do not create empty overlays with the evaporate property (Bug#9642).
4659 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4660 if it becomes empty after its bounds are adjusted to fit within
4661 its buffer. Without this fix, in a nonempty buffer (let ((o
4662 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4663 yields an empty overlay that has the evaporate property, which is
4664 not supposed to happen.
4666 Fix minor GTK3 problems found by static checking.
4667 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4668 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4669 (struct _EmacsFixedClass, emacs_fixed_get_type):

4679 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4681 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4682 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4684 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4686 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4687 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4688 (__malloc_size_t, __malloc_ptrdiff_t):
4689 Remove. All uses removed, replaced by the definiens if needed,
4690 since we can assume C89 or better now.
4691 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4692 (protect_malloc_state, align, get_contiguous_space)
4693 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4699 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4700 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4701 Define using prototypes, not old style.
4702 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4703 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4704 (align): Don't assume that signed integer overflow wraps around.
4705 Omit unused local var.
4706 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4707 (_free_internal_nolock, memalign, mallochook, reallochook):

4711 (struct hdr): The 'magic' member is now size_t, not unsigned long.
4713 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4715 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

4766 * alloc.c: Handle unusual debugging option combinations.
4767 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4768 since the two debugging options are incompatible.

4781 * sysdep.c [__FreeBSD__]: Minor cleanups.
4782 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4783 Use Emacs indenting style more consistently. Avoid some casts.
4784 Use 'double' consistently rather than mixing 'float' and 'double'.
4786 2012-04-21 Eduard Wiebe <usenet@pusto.de>
4788 * sysdep.c (list_system_processes, system_process_attributes):

4823 row, return zero immediately.
4824 (try_cursor_movement): If inside continuation line, don't back up
4825 farther than the first row after the header line, if any.
4826 Don't consider the header-line row as "partially visible", even if
4827 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4829 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4876 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
4877 (r_alloc_sbrk): Now static.
4879 Improve ralloc.c interface checking.
4880 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
4881 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
4882 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
4883 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
4884 [REL_ALLOC]: ... to here, to check interface.
4885 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4886 Remove decls. This fixes an "It stinks!".
4888 * alloc.c (which_symbols): Fix alignment issue / type clash.
4890 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4892 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
4893 (struct Lisp_Misc_Any): Likewise.
4894 (struct Lisp_Free): Likewise.
4895 * alloc.c (union aligned_Lisp_Symbol): Define.

4900 aligned_Lisp_Misc instead of union Lisp_Misc.
4901 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
4903 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4905 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4906 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4907 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4908 * s/netbsd.h, s/sol2-6.h:
4909 Remove definition of GC_MARK_STACK, since the default now works.
4910 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4911 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4912 no longer the default.
4913 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4915 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4917 * lread.c (lisp_file_lexically_bound_p):
4918 Fix hang at ";-*-\n" (bug#11238).

4925 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
4927 * nsterm.m (constrainFrameRect): Always constrain when there is only
4928 one screen (Bug#10962).
4930 2012-04-13 Ken Brown <kbrown@cornell.edu>
4932 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
4934 2012-04-13 Reuben Thomas <rrt@sc3d.org>

4938 2012-04-11 Daniel Colascione <dancol@dancol.org>
4940 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4941 against is gone. It's better to use vfork now so that when Cygwin
4942 gains a new, working vfork, we use it automatically (bug#10398).
4944 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4946 * window.c (save_window_save): Obey window-point-insertion-type.

4956 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
4958 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
4959 (force_quit_count): New var.
4960 (handle_interrupt): Use it.
4962 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
4964 * w32.c (w32_delayed_load): Record the full path of the library
4965 being loaded (bug#10424).
4967 2012-04-09 Glenn Morris <rgm@gnu.org>
4969 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4970 not just in the obarray, before snarfing them. (Bug#11036)
4972 * Makefile.in ($(leimdir)/leim-list.el):
4973 Pass EMACS rather than BUILT_EMACS.
4975 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4977 * process.c (make_process):
4978 * process.h: Add integer `gnutls_handshakes_tried' member to
4981 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4982 Add convenience `GNUTLS_LOG2i' macro.
4984 * gnutls.c (gnutls_log_function2i): Convenience log function.
4985 (emacs_gnutls_read): Use new log functions,
4986 `gnutls_handshakes_tried' process member, and
4987 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4988 attempts per process (connection).
4990 2012-04-09 Chong Yidong <cyd@gnu.org>

4997 * minibuf.c (Fread_variable): Callers changed.
4999 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5001 * xdisp.c (set_cursor_from_row): If the display string appears in
5002 the buffer at position that is closer to point than the position
5003 after the display string, display the cursor on the first glyph of
5004 the display string. Fixes cursor display when a 'display' text
5005 property immediately follows invisible text. (Bug#11094)
5007 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5009 composite.c: use 'double' consistently
5010 * composite.c (get_composition_id): Use 'double' consistently
5011 instead of converting 'float' to 'double' and vice versa; this is
5012 easier to understand and avoids a GCC warning.
5014 2012-04-09 Glenn Morris <rgm@gnu.org>
5016 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5017 preparation for dumping it with emacs. (Bug#4789)

5026 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5028 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5031 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5033 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5034 Remove unused local variable.
5036 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5038 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5039 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5040 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5041 objects, as mark_maybe_pointer will catch them otherwise.
5042 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5043 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5045 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5047 Fix typo that broke non-Windows builds.
5048 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5050 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5052 Support building on MS-Windows with libxml2.
5054 * makefile.w32-in (OBJ2): Add xml.$(O).
5055 (GLOBAL_SOURCES): Add xml.c.
5056 ($(BLD)/xml.$(O)): New dependency list.
5058 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5059 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5060 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5061 [!WINDOWSNT]: New macros.
5062 (init_libxml2_functions, libxml2_loaded_p): New functions.
5063 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5064 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5065 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5066 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5068 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5069 Call init_libxml2_functions before calling libxml2 functions.
5070 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5072 * emacs.c: Don't include libxml/parser.h.
5073 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5074 xmlCleanupParser directly.
5076 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5078 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5080 * indent.c (Fvertical_motion): If there is a display string at
5081 point, use it.vpos to compute how many lines to backtrack after
5082 move_it_to point. (Bug#11133)
5084 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5086 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5087 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5088 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5089 macros related to unification of CJK characters. For the details,
5090 see the discussion following the message here:
5091 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5093 2012-04-04 Chong Yidong <cyd@gnu.org>
5095 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5097 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5099 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5100 instead of alloca. (Bug#11138)
5102 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5104 * w32menu.c (is_simple_dialog): Properly check lisp types.
5107 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5109 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5110 position we get to after a call to move_it_to fails the
5111 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5112 only if we wind up in a string from display property. (Bug#11063)
5114 * window.c (Fdelete_other_windows_internal): Invalidate the row
5115 and column information about mouse highlight, so that redisplay
5116 restores it after reallocating the glyph matrices. (Bug#7464)
5118 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5119 string comes from a `display' text property, use the buffer
5120 position of that property as if we actually saw that position in
5122 (move_it_by_lines): Remove the assertion that
5123 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5124 violated when there's a before-string at the beginning of a line.
5127 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5129 * xdisp.c (append_space_for_newline): If the default face was
5130 remapped, use the remapped face for the appended newline.
5131 (extend_face_to_end_of_line): Use the remapped default face for
5132 extending the face to the end of the line.
5133 (display_line): Call extend_face_to_end_of_line when the default
5134 face was remapped. (Bug#11068)
5136 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5138 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5140 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5142 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5144 2012-03-27 Glenn Morris <rgm@gnu.org>
5146 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5149 2012-03-26 Kenichi Handa <handa@m17n.org>
5151 * dispextern.h (struct glyph): Fix previous change. Change the
5152 bit length of glyphless.ch to 25 (Bug#11082).
5154 2012-03-26 Chong Yidong <cyd@gnu.org>
5156 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5157 (command_loop_1): Use it; inhibit selection update for
5158 handle-select-window too (Bug#8996).
5160 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5162 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5164 2012-03-25 Kenichi Handa <handa@m17n.org>
5166 * dispextern.h (struct glyph): Change the bit length of
5167 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5169 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5171 * s/ms-w32.h (tzname): Include time.h before redirecting to
5172 _tzname. Fixes the MSVC build. (Bug#9960)
5174 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5176 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5179 * xterm.c (XTread_socket): Only modify handling_signal if
5180 !SYNC_INPUT. (Bug#11080)
5182 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5184 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5185 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5186 when fetching a multibyte character consumes more bytes than
5187 CHAR_BYTES returns, due to unification of CJK characters in
5188 string_char. (Bug#11073)
5190 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5192 * process.c (wait_reading_process_output): Handle pty disconnect
5193 by refraining from sending oneself a SIGCHLD (bug#10933).

5202 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5204 2012-03-21 Chong Yidong <cyd@gnu.org>
5206 * xfaces.c (Vface_remapping_alist): Doc fix.
5208 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5210 * w32proc.c (Fw32_set_console_codepage)
5211 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5214 2012-03-20 Chong Yidong <cyd@gnu.org>
5216 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5217 to reflect default non-nil value of redisplay-dont-pause.
5219 2012-03-19 Kenichi Handa <handa@m17n.org>
5221 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5222 it fit in a valid range (Bug#11003).
5224 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5226 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5227 that is not from display property, accept the row as a "cursor
5228 row" if one of the string's character has a non-nil `cursor'
5229 property. Fixes cursor positioning when there are newlines in
5230 overlay strings, e.g. in icomplete.el. (Bug#11035)
5232 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5234 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5236 2012-03-12 Chong Yidong <cyd@gnu.org>
5238 * eval.c (inhibit_lisp_code): Rename from
5239 inhibit_window_configuration_change_hook; move from window.c.
5241 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5242 * window.c (run_window_configuration_change_hook)
5243 (syms_of_window): Callers changed.
5245 2012-03-11 Chong Yidong <cyd@gnu.org>
5247 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5249 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5251 2012-03-10 Chong Yidong <cyd@gnu.org>
5253 * frame.c (other_visible_frames): Don't assume the selected frame
5254 is visible (Bug#10955).
5256 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5258 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5260 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5262 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5263 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5266 2012-03-03 Glenn Morris <rgm@gnu.org>
5268 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5270 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5272 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5273 position past the first glyph_row that ends at ZV. (Bug#10902)
5274 (redisplay_window, next_element_from_string): Fix typos in
5276 (redisplay_window): Pass to move_it_vertically the margin in
5277 pixels, not in screen lines.
5279 2012-03-02 Glenn Morris <rgm@gnu.org>
5281 * buffer.c (buffer-list-update-hook): Doc fix.
5283 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5285 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5286 push_it before setting up the iterator for the first overlay
5287 string, even if we have an empty string loaded.
5288 (next_overlay_string): If there's an empty string on the iterator
5289 stack, pop the stack. (Bug#10903)
5291 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5293 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5294 Suggested by Stefan Monnier in
5295 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5296 * alloc.c (widen_to_Lisp_Object): New static function.
5297 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5298 and widening them to Lisp_Objects. This would work even if
5299 USE_LSB_TAG is defined and wide integers are used, which might
5300 happen in a future version of Emacs.
5302 2012-02-25 Chong Yidong <cyd@gnu.org>
5304 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5307 * xselect.c (Fx_selection_exists_p): Doc fix.
5308 (x_clipboard_manager_save_all): Print an informative message
5309 before saving to clipboard manager.
5311 2012-02-24 Chong Yidong <cyd@gnu.org>
5313 * keyboard.c (process_special_events): Handle all X selection
5314 requests in kbd_buffer, not just the next one (Bug#8869).
5316 2012-02-23 Chong Yidong <cyd@gnu.org>
5318 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5319 call when setting menu-bar-lines and tool-bar-lines parameters.
5320 (unwind_create_frame_1): New helper function.
5322 * window.c (inhibit_window_configuration_change_hook): New var.
5323 (run_window_configuration_change_hook): Obey it.
5324 (syms_of_window): Initialize it.
5326 2012-02-22 Chong Yidong <cyd@gnu.org>
5328 * xterm.c (x_draw_image_relief): Add missing type check for
5329 Vtool_bar_button_margin (Bug#10743).
5331 2012-02-21 Chong Yidong <cyd@gnu.org>
5333 * fileio.c (Vfile_name_handler_alist): Doc fix.
5335 * buffer.c (Fget_file_buffer): Protect against invalid file
5336 handler return value.
5338 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5340 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5341 when computing $valmask.
5343 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5344 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5345 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5346 It's useless in that case, and it can cause problems on hosts
5347 that allocate halves of EMACS_INT values separately.
5348 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5349 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5350 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where

6141 to 4 (xorl, subq, cmpq, setbe).
6142 * alloc.c (pure): Always extern now, since that's the

6155 behave as if the cursor position were at the window margin.
6157 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6158 and the cursor position is out of bounds, behave as if the cursor
6159 position were at the window margin. (Bug#10075)
6161 2011-11-18 Chong Yidong <cyd@gnu.org>
6163 * window.c (Fwindow_combination_limit): Make first argument

6185 compute_line_metrics.
6186 (compute_line_metrics): Call row_hash, instead of computing the
6189 * dispnew.c (verify_row_hash): Call row_hash for computing the
6190 hash code of a row, instead of duplicating code from xdisp.c.
6192 * dispextern.h (row_hash): Add prototype.
6194 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6196 * frame.c (delete_frame): Don't delete the terminal when the last

6228 * image.c (imagemagick_load_image): Fix typo.
6230 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6232 * xdisp.c (display_line): Move the call to

6351 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6352 This is also needed for porting to any host where GC_MARK_STACK is
6353 not GC_MAKE_GCPROS_NOOPS.
6354 (which_symbols): Use it.
6356 2011-11-07 Kenichi Handa <handa@m17n.org>

6369 * xmenu.c (cleanup_widget_value_tree): New function.
6370 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6377 (window_box_width, window_box_left, window_box_left_offset)
6378 (window_box_right, window_box_right_offset): Declare extern.
6379 Otherwise, these inline functions do not conform to C99 and
6380 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6381 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6382 * intervals.c (adjust_intervals_for_insertion)
6383 (adjust_intervals_for_deletion): Now extern, because otherwise the
6384 extern inline functions 'offset_intervals' couldn't refer to it.
6385 (static_offset_intervals): Remove.
6386 (offset_intervals): Rewrite using the old contents of
6387 static_offset_intervals. The old version didn't conform to C99
6388 because an extern inline function contained a reference to an
6389 identifier with static linkage.
6391 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6393 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6411 (Fwindow_vscroll): Doc fix.
6412 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6413 argument, since it makes no sense to pass a live window and for
6414 consistency with window-child.

6444 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6445 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6446 Move terminal->reference_count++ just before making the frame official

6622 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6624 (w32font_open_internal, compute_metrics):
6625 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6626 instead of calling the "wide" APIs directly.
6628 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

6695 non-ET, non-BN character we find, in addition to its position.
6696 (bidi_level_of_next_char): Invalidate next_en_type when
6697 next_en_pos is over-stepped.
6699 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6701 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6702 * editfns.c: Rewrite current-time-zone so that it invokes
6703 the equivalent of (format-time-string "%Z") to get the time zone name.
6704 This fixes a bug when the time zone name contains characters that
6705 need converting from the system time locale to Emacs internal format.
6706 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6707 that patch fixed format-time-string to do the conversion, but
6708 I forgot to fix current-time-zone.
6709 (format_time_string): New function, containing most of
6710 what Fformat_time_string used to contain.
6711 (Fformat_time_string): Rewrite in terms of format_time_string.
6712 This doesn't change this function's behavior.
6713 (current-time-zone): Rewrite to use format_time_string.
6714 This fixes the bug reported by Michael Schierl in
6715 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6716 Jason Rumney's 2007-06-07 change worked around this bug, but
6718 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6720 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6722 * xdisp.c (start_display): If the character at POS is displayed
6723 via a display vector, reset IT->current.dpvec_index to zero.
6724 (try_window_reusing_current_matrix): If a line ends in a display
6725 vector or the next line starts in a display vector, continue
6726 redrawing the window even though the character position of
6727 start_row was reached.
6730 2011-10-18 Chong Yidong <cyd@gnu.org>
6732 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6733 with nobreak-char-display too.
6735 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6737 Fix part 3 of bug#9771.
6738 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6739 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6740 non-neutral characters if the current character is a paragraph
6741 separator (a.k.a. Newline). This avoids running the same
6742 expensive loop twice, once when we consume the preceding newline
6743 and the other time when the line actually needs to be displayed.
6744 Avoid the loop when we see neutrals on the base embedding level
6745 following a character whose directionality is the same as the
6746 paragraph's. This avoids running the expensive loop when a line
6747 ends in a long sequence of neutrals, like control characters.
6748 Add assertion against STRONG_AL type. Slightly rearrange code
6749 that determines the type of a neutral given the first non-neutral
6751 (bidi_level_of_next_char): Set next_en_pos to zero when
6752 invalidating its info.
6754 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6756 * xdisp.c (push_display_prop): Determine whether to record string
6757 or buffer position by IT->string, not by IT->method. Allow
6758 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6759 (move_it_vertically_backward): Don't look for character position
6760 immediately after the newline when in a continuation line.
6763 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6765 * window.c (coordinates_in_window): Rewrite and delabelize
6766 vertical border check. (Bug#5357) (Bug#9618)
6768 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6770 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained

6775 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6776 avoid crash when xmalloc overrun checking is enabled.
6778 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6780 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6781 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6782 cursor motion with <left> and <right> arrow keys.
6784 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6785 some callers set that themselves.
6787 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6789 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6790 display string and the previous row comes from the same string and
6791 is empty. (Bug#9739) (Bug#9738)
6793 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6795 * doc.c (get_doc_string): Encode file name (bug#9735).
6797 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6799 * bidi.c (bidi_level_of_next_char):
6800 * xdisp.c (get_visually_first_element): Remove old incorrect
6801 comments regarding the Unicode Line Separator character.
6803 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6805 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

6808 boundary if nzombies > MAX_ZOMBIES.

6811 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6813 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6814 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6816 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6817 Some packages use them to denote characters with modifiers.
6819 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6821 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6822 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6823 matching a pp-number. Rename parameter var to var1.
6825 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6827 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6829 2011-10-08 Glenn Morris <rgm@gnu.org>
6831 * callint.c (Fcall_interactively): Give a more explicit error for the
6832 'c' case with a non-character input. (Bug#8479)
6834 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6836 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6838 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6839 lines that are hscrolled on the left.
6841 * dispnew.c (buffer_posn_from_coords): Account for a possible
6842 presence of header-line. (Bug#4426)
6844 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6846 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6847 Don't advertise functionality which we discourage or doesn't work.
6849 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6851 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6852 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6853 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6854 this makes Emacs dump core during garbage collection on rare
6855 occasions. sizeof is obviously inferior to offsetof here, so
6856 stick with offsetof.
6857 (GC_POINTER_ALIGNMENT): New macro.
6858 (mark_memory): Omit 3rd (offset) arg; caller changed.
6859 Don't assume EMACS_INT alignment is the same as pointer alignment.
6861 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6863 * keyboard.c (read_key_sequence_remapped): New var.
6864 (read_key_sequence): Compute remapping in the right buffer.
6865 (command_loop_1): Use read_key_sequence's remapping directly.
6867 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6869 * dired.c (file_name_completion): Don't expand file name.
6870 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6871 before checking file name handler.
6873 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6874 they've been requested explicitly (bug#9591).
6876 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6878 * keymap.c (Fsingle_key_description): Use make_specified_string
6879 instead of build_string to build string from push_key_description.
6882 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6884 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6885 This fixes a Y2038 bug on 64-bit hosts.
6886 * buffer.c (reset_buffer):
6887 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6888 (Fclear_buffer_auto_save_failure):
6889 Use 0, not -1, to represent an unset failure time, since time_t
6890 might not be signed.
6892 Remove dependency on glibc malloc internals.
6893 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6894 Move back here from lisp.h, but with their new implementations.
6895 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6896 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6897 * charset.c (charset_table_init): New static var.
6898 (syms_of_charset): Use it instead of xmalloc. This removes a
6899 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6900 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6901 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6902 Move back to alloc.c.
6903 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6904 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6906 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6908 * nsterm.m (windowDidResize): Call x_set_window_size only when
6909 ns_in_resize is true. Otherwise set pixelwidth/height and
6910 call change_frame_size (Bug#9628).
6912 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6914 Port --enable-checking=all to Fedora 14 x86-64.
6915 * charset.c (syms_of_charset): Also account for glibc malloc's
6916 internal overhead when calculating the initial malloc maximum.
6918 Port --enable-checking=all to Fedora 14 x86.
6919 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6921 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6922 (overrun_check_realloc, overrun_check_free):
6923 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6924 That way, xmalloc returns a properly-aligned pointer even if
6925 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6926 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6927 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6928 into account when calculating the initial malloc maximum.
6929 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6930 Move here from alloc.c, so that charset.c can use it too.
6931 Properly align; the old code wasn't right for common 32-bit hosts
6932 when configured with --enable-checking=all.
6933 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6934 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6936 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6938 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6941 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6943 * xdisp.c (compute_display_string_end): If there's no display
6944 string at CHARPOS, return -1.
6946 * bidi.c (bidi_fetch_char): When compute_display_string_end
6947 returns a negative value, treat the character as a normal
6948 character not covered by a display string. (Bug#9624)
6950 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6952 * lread.c (Fread_from_string): Fix typo in docstring.
6954 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6956 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6957 newline, reseat the iterator instead of bidi-iterating there one
6958 character at a time. (Bug#9610)
6959 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6960 TO_CHARPOS if the bidi iterator is at base embedding level.
6962 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6964 * lread.c (readevalloop): Use correct code for NBSP.
6965 (read1): Likewise. (Bug#9608)
6967 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6969 * dbusbind.c (Fdbus_register_signal): When service is not
6970 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6972 2011-09-25 Glenn Morris <rgm@gnu.org>
6974 * buffer.c (truncate-lines): Doc fix.
6976 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6978 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6979 (Fset_window_next_buffers): Doc fix.
6981 2011-09-24 Glenn Morris <rgm@gnu.org>
6983 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6985 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6987 Fix minor problems found by static checking.
6988 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6989 * indent.c (Fvertical_motion): Fix == vs = typo.
6991 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6993 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6994 Default value is now t. Doc fix.
6996 * indent.c (Fvertical_motion): Compute and apply the overshoot
6997 logic when moving up, not only when moving down. Fix the
6998 confusing name and values of the it_overshoot_expected variable;
6999 logic changes accordingly. (Bug#9254) (Bug#9549)
7001 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7002 CHARPOS is covered by a display string which includes newlines.
7003 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7004 is covered by a display string with embedded newlines.
7006 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7008 * dbusbind.c (Fdbus_register_signal): Add match rule to
7009 Vdbus_registered_objects_table. (Bug#9581)
7010 (Fdbus_register_method, Vdbus_registered_objects_table):
7013 2011-09-24 Jim Meyering <meyering@redhat.com>
7015 do not ignore write error for any output size
7016 The previous change was incomplete.
7017 While it makes emacs --batch detect the vast majority of stdout
7018 write failures, errors were still ignored whenever the output size is
7019 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7020 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7021 && echo FAIL: ignored write error
7022 FAIL: ignored write error
7023 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7024 && echo FAIL: ignored write error
7025 FAIL: ignored write error
7026 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7028 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7030 * emacs.c (Fkill_emacs): In noninteractive mode exit
7031 non-successfully if a write error occurred on stdout. (Bug#9574)
7033 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7035 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7038 * dispextern.h (struct it): Update the comment documenting what
7041 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7043 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7044 a display string, extend search for cursor position to end of row.
7045 (find_row_edges): If the row ends in a newline from a display
7046 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7047 Handle the case of a display string with multiple newlines.
7048 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7049 non-empty line. Fixes confusing cursor motion with arrow keys at
7050 the beginning of a line that starts with whitespace.
7052 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7054 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7057 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7059 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7062 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7064 * xdisp.c (display_line): Record maximum and minimum buffer
7065 positions even if no glyphs were produced (e.g., by a zero-width
7066 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7067 buffer positions that will be removed from the glyph row because
7069 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7070 column is beyond frame width: don't subtract 1 "pixel" when
7071 computing width of the stretch.
7072 (reseat_at_next_visible_line_start): Undo the change made on
7073 2011-09-17 that saved paragraph information and restored it after
7074 the call to `reseat'. (Bug#9545)
7076 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7078 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7079 and turn window cursor on if cleared (Bug#9415).
7081 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7083 * search.c (boyer_moore): Take unibyte characters from pattern
7084 literally. (Bug#9458)
7086 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7088 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7090 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7092 Fix minor problem found by static checking.
7093 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7094 initialized, to pacify gcc -Wuninitialized.
7096 * fileio.c: Report proper errno when syscall falls.
7097 (Finsert_file_contents): Save and restore errno,
7098 so that report_file_error outputs the correct diagnostic.
7099 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7101 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7103 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7105 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7107 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7108 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7110 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7112 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7113 about the current paragraph and restore it after the call to reseat.
7115 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7116 (bidi_find_paragraph_start): Search back for paragraph beginning
7117 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7118 (bidi_move_to_visually_next): Only trigger paragraph-related
7119 computations when the last character is a newline or at EOB, not
7120 just any NEUTRAL_B. (Bug#9470)
7122 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7123 truncated lines if point is covered by a display string. (Bug#9524)
7125 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7127 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7128 (cons_to_x_long): New function.
7129 (lisp_data_to_selection_data): Use it. Correct the test for
7130 short-versus-long data; it was negated. Break out of vector
7131 loop, for efficiency, when a long datum is discovered.
7133 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7135 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7137 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7139 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7140 GCC PR/17406) by declaring this function with external scope.
7142 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7144 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7145 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7147 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7149 * editfns.c (Fformat): Correctly handle text properties on "%%".
7151 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7153 * xterm.c (x_draw_composite_glyph_string_foreground):
7154 * w32term.c (x_draw_composite_glyph_string_foreground):

7156 * composite.c (composition_update_it, get_composition_id):
7157 * xdisp.c (get_next_display_element)
7158 (fill_composite_glyph_string): Add comments about special meaning
7159 of TAB characters in a composition.
7161 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7163 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7164 This occurs when processing a multibyte format.
7165 Problem reported by Wolfgang Jenker.
7167 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7169 * xdisp.c (try_cursor_movement): Only check for exact match if
7170 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7172 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7174 Remove unused external symbols.
7175 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7176 * xdisp.c (calc_pixel_width_or_height): Now static.
7177 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7178 * indent.c (check_display_width):
7179 * w32term.c: Fix comment to match code.
7180 * xterm.c, xterm.h (x_catching_errors): Remove.
7182 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7184 * xselect.c: Use signed conversions more consistently (Bug#9498).
7185 (selection_data_to_lisp_data): Assume incoming selection data are
7186 signed integers, not unsigned. This is to be consistent with
7187 outgoing selection data, which was modified to use signed integers
7188 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7189 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7190 expects long, not unsigned long.
7192 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7194 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7195 computation of loop end. Reported by Johan Bockgård
7198 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7200 * frame.c (Fother_visible_frames_p): Function deleted.
7202 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7204 * indent.c (compute_motion): Process display vector front to back
7205 rather than the other way around. (Bug#2496)
7207 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7209 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7211 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7213 * minibuf.c (Fread_from_minibuffer): Doc fix.
7215 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7217 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7218 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7220 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7222 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7223 value for non-existent files.
7225 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7227 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7228 set its "size" to -1. This will set the modtime_size field of
7229 the corresponding buffer to -1, which is what
7230 verify-visited-file-modtime expects for files that do not exist.
7233 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7235 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7237 * lisp.h: ... from here. push_key_description is no longer
7238 defined in keyboard.c, so its declaration should not be in
7239 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7240 logically belongs with push_key_description.
7242 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7244 * buffer.h: Include <sys/types.h> instead of <time.h>.
7245 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7246 Problem reported by Herbert J. Skuhra.
7248 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7250 * xml.c (parse_region): Make the parsing work for
7251 non-comment-starting XML files again (bug#9144).
7253 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>

7258 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7260 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7261 redisplay in small windows.
7263 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7265 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7267 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7269 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7270 Operate on live windows only.
7272 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

7276 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7278 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7279 only under bidi iteration.
7281 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7283 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7285 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7287 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7288 Without this fix, the command to link temacs failed due to an
7289 undefined symbol __builtin_isnan. This is because
7290 /usr/include/iso/math_c99.h #defines isnan(x) to
7291 __builtin_isnan(x), but the bundled gcc, which identifies itself
7292 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7294 * floatfns.c (isnan): #undef, and then #define to a clone of
7296 (Fisnan): Always define, since it's always available now.
7297 (syms_of_floatfns): Always define isnan at the Lisp level.
7299 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7301 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7303 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7305 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7306 The previous code assumed that file offsets (off_t values) fit in
7307 EMACS_INT variables, which is not true on typical 32-bit hosts.
7308 The code messed up by falsely reporting buffer overflow in cases
7309 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7310 when "big" contains more than 2**29 bytes, even though this
7311 inserts just one byte and does not overflow the buffer.
7312 (Finsert_file_contents): Store file offsets as off_t
7313 values, not as EMACS_INT values. Check for overflow when
7314 converting between EMACS_INT and off_t. When checking for
7315 buffer overflow or for overlap, take the offsets into account.
7316 Don't use EMACS_INT for small values where int suffices.
7317 When checking for overlap, fix a typo: ZV was used where
7318 ZV_BYTE was intended.
7319 (Fwrite_region): Don't assume off_t fits into 'long'.
7320 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7322 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7324 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7326 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7328 sprintf-related integer and memory overflow issues (Bug#9412).
7330 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7331 (esprintf, exprintf, evxprintf): New functions.
7332 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7333 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7334 (modify_event_symbol): Do not assume that the length of
7335 name_alist_or_stem is safe to alloca and fits in int.
7336 (Fexecute_extended_command): Likewise for function name and binding.
7337 (Frecursion_depth): Wrap around reliably on integer overflow.
7338 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7339 since some callers pass EMACS_INT values.
7340 (Fsingle_key_description): Don't crash if symbol name contains more
7341 than MAX_ALLOCA bytes.
7342 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7343 (get_minibuffer): Arg is now EMACS_INT, not int.
7344 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7345 (esprintf, exprintf, evxprintf): New decls.
7346 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7348 * dbusbind.c (signature_cat): New function.
7349 (xd_signature, Fdbus_register_signal):
7350 Do not overrun buffer; instead, report string overflow.
7352 * dispnew.c (add_window_display_history): Don't overrun buffer.
7353 Truncate instead; this is OK since it's just a log.
7355 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7356 even if the time zone offset is outlandishly large.
7357 Don't mishandle offset == INT_MIN.
7359 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7360 when creating daemon; the previous buffer-overflow check was incorrect.
7362 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7363 which has the guts of the old verror function.
7365 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7366 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7368 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7369 (font_unparse_xlfd): Don't blindly alloca long strings.
7370 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7371 fits in int, when using sprintf. Use single snprintf to count
7372 length of string rather than counting it via multiple sprintfs;
7373 that's simpler and more reliable.
7374 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7375 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7376 sprintf, in case result does not fit in int.
7378 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7379 (fontset_from_font): Print it.
7381 * frame.c (tty_frame_count): Now printmax_t, not int.
7382 (make_terminal_frame, set_term_frame_name): Print it.
7383 (x_report_frame_params): In X, window IDs are unsigned long,
7384 not signed long, so print them as unsigned.
7385 (validate_x_resource_name): Check for implausibly long names,
7386 and don't assume name length fits in 'int'.
7387 (x_get_resource_string): Don't blindly alloca invocation name;
7388 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7391 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7392 (xg_check_special_colors, xg_set_geometry):
7393 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7395 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7396 Use esprintf, not sprintf, in case result does not fit in int.
7398 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7399 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7400 it as a large positive number.
7401 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7402 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7404 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7405 in case result does not fit in int.
7407 * print.c (float_to_string): Detect width overflow more reliably.
7408 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7409 buffer overrun. Don't assume list length fits in 'int'. Treat
7410 print length of 0 as 0, not as infinity; to be consistent with other
7411 uses of print length in this function. Don't overflow print length
7412 index. Don't assume hash table size fits in 'long', or that
7413 vectorlike size fits in 'unsigned long'.
7415 * process.c (make_process): Use printmax_t, not int, to format
7416 process-name gensyms.
7418 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7420 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7421 to avoid potential buffer overrun.
7423 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7424 if X resource line is longer than 512 bytes.
7426 * xfns.c (x_window): Make sprintf buffer a bit bigger
7427 to avoid potential buffer overrun.
7429 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7431 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7433 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7435 Integer overflow fixes for scrolling, etc.
7436 Without these, Emacs silently mishandles large integers sometimes.
7437 For example, "C-u 4294967297 M-x recenter" was treated as if
7438 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7440 * xdisp.c (try_window_id): Check Emacs fixnum range before
7441 converting to 'int'.
7443 * window.c (window_scroll_line_based, Frecenter):
7444 Check that an Emacs fixnum is in range before assigning it to 'int'.
7445 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7446 values converted from Emacs fixnums.
7447 (Frecenter): Don't wrap around a line count if it is out of 'int'
7448 range; instead, treat it as an extreme value.
7449 (Fset_window_configuration, compare_window_configurations):
7450 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7452 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7453 that can exceed INT_MAX. Check that EMACS_INT value is in range
7454 before assigning it to the (possibly-narrower) index.
7455 (match_limit): Don't assume that a fixnum can fit in 'int'.
7457 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7460 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7461 (Fvertical_motion): Don't wrap around LINES values that don't fit
7462 in 'int'. Instead, treat them as extreme values. This is good
7463 enough for windows, which can't have more than INT_MAX lines anyway.
7465 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7467 * Require libxml/parser.h to avoid compilation warning.
7469 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7471 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7472 since this reportedly can destroy thread storage.
7474 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7476 * syntax.c (find_defun_start): Update all cache variables if
7477 exiting early (Bug#9401).
7479 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7481 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7483 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7484 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7485 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7487 * term.c (tty_append_glyph): New function.
7488 (produce_stretch_glyph): Static function and its prototype deleted.
7490 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7493 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7495 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7496 when checking :margin (Bug#9390).
7497 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7498 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7499 so that the name doesn't mislead. All uses changed.
7501 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7503 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7506 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7508 * xdisp.c (move_it_to): Don't bail out early when reaching
7509 position beyond to_charpos, if we are scanning backwards.
7510 (move_it_vertically_backward): When DY == 0, make sure we get to
7511 the first character in the line after the newline.
7513 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7515 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7516 (ccl_driver): Do not generate an out-of-range pointer.
7517 (Fccl_execute_on_string): Remove unnecessary check for
7518 integer overflow, noted by Stefan Monnier in
7519 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7520 Remove a FIXME that didn't need fixing.
7521 Simplify the newly-introduced buffer reallocation code.
7523 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7525 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7527 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7529 Integer and memory overflow issues (Bug#9196).
7531 * doc.c (get_doc_string): Rework so that
7532 get_doc_string_buffer_size is the actual buffer size, rather than
7533 being 1 less than the actual buffer size; this makes xpalloc more
7536 * image.c (x_allocate_bitmap_record, cache_image):
7537 * xselect.c (Fx_register_dnd_atom):
7538 Simplify previous changes by using xpalloc.
7540 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7541 since either will do and ptrdiff_t is convenient with xpalloc.
7543 * charset.c (charset_table_size)
7544 (struct charset_sort_data.priority): Now ptrdiff_t.
7545 (charset_compare): Don't overflow if priorities differ greatly.
7546 (Fsort_charsets): Don't assume list length fits in int.
7547 Check for size-calculation overflow when allocating sort data.
7548 (syms_of_charset): Allocate an initial charset table that is
7549 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7551 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7553 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7554 The actual value is always <= INT_MAX, and leaving it unsigned made
7555 overflow checking harder.
7557 * dispextern.h (struct glyph_matrix.rows_allocated)
7558 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7559 with xpalloc. The values are still always <= INT_MAX.
7561 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7563 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7564 (SAFE_NALLOCA): New macro.
7566 * region-cache.c (struct boundary.pos, find_cache_boundary)
7567 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7568 (set_cache_region, invalidate_region_cache)
7569 (revalidate_region_cache, know_region_cache, region_cache_forward)
7570 (region_cache_backward, pp_cache):
7571 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7572 so that ptrdiff_t * can be passed to xpalloc.
7573 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7574 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7575 (pp_cache): Don't assume cache_len fits in int.
7576 * region-cache.h: Adjust extern decls to match.
7578 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7579 EMACS_INT, since either will do, for xpalloc.
7581 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7582 (xnmalloc, xnrealloc, xpalloc): New functions.
7584 * bidi.c (bidi_shelve_header_size): New constant.
7585 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7586 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7588 * bidi.c (bidi_cache_shrink):
7589 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7591 Don't update size of array until after memory allocation succeeds,
7592 because xmalloc/xrealloc may not return.
7593 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7594 now that we have proper integer overflow checking.
7595 (record_overlay_string, overlay_strings): Catch overflows when
7596 calculating size of overlay_str_buf.
7598 * callproc.c (Fcall_process): Check for size overflow when
7599 calculating size of args2.
7600 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7601 Normally we prefer signed values, but sticking with ptrdiff_t would
7602 require adding more-complicated checks.
7604 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7605 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7606 Redo buffer-overflow calculations to avoid integer overflow.
7607 Add a FIXME comment where memory seems to be over-allocated.
7609 * character.c (Fstring): Check for size-calculation overflow.
7611 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7612 unnecessary integer overflow. Check for size overflow.
7613 (encode_coding_object): Don't update size until xmalloc succeeds.
7615 * composite.c (get_composition_id): Check for overflow in glyph
7616 length calculations.
7618 Integer and memory overflow fixes for display code.
7619 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7620 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7621 (scrolling_window): Check for overflow in size calculations.
7622 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7623 Don't assume glyph table len fits in int.
7624 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7625 (row_table_size): Now ptrdiff_t, not int.
7626 (scrolling_window): Avoid overflow in size calculations.
7627 Don't update size until allocation succeeds.
7628 * fns.c (concat): Check for overflow in size calculations.
7629 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
7630 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7631 (NEXT_ALMOST_PRIME_LIMIT): New constant.
7633 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7634 (get_doc_string): Check for size calculation overflow.
7635 Don't update size until allocation succeeds.
7636 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7637 EMACS_INT, where ptrdiff_t will do.
7638 (Fsubstitute_command_keys): Check for string overflow.
7640 * editfns.c (set_time_zone_rule): Don't assume environment length
7642 (message_length): Now ptrdiff_t, not int.
7643 (Fmessage_box): Don't update size until allocation succeeds.
7644 Don't assume message length fits in int.
7645 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7647 * emacs.c (main): Do not reallocate argv, since there is a null at
7648 the end that can be overwritten, and this way there's no need to
7649 worry about size-calculation overflow.
7650 (sort_args): Check for size-calculation overflow.
7652 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7654 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7656 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7657 (x_set_scroll_bar_width, x_figure_window_size):
7658 Check for integer overflow.
7659 (x_set_alpha): Do not assume XINT fits in int.
7661 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7662 This is for the members text_lines, text_cols, total_lines, total_cols,
7663 where the system imposes an 'int' limit.
7665 * fringe.c (Fdefine_fringe_bitmap):
7666 Don't update size until alloc works.
7668 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7669 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7671 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7672 Check for size-calculation overflow.
7673 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7674 do, as we prefer signed integers.
7675 (id_to_widget.max_size, id_to_widget.used)
7676 (xg_store_widget_in_map, xg_remove_widget_from_map)
7677 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7678 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7679 Use and return ptrdiff_t, not int.
7680 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7681 * gtkutil.h: Change prototypes to match the above.
7683 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7684 are duplicate now that they've been promoted to lisp.h.
7685 (x_allocate_bitmap_record, x_alloc_image_color)
7686 (make_image_cache, cache_image, xpm_load):
7687 Don't update size until alloc is done.
7688 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7690 Check for size calculation overflow.
7691 (ct_colors_allocated_max): New constant.
7692 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

7697 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7698 Use ptrdiff_t, not int, to count maps.
7699 (read_char_minibuf_menu_prompt): Check for overflow in size
7700 calculations. Don't update size until allocation succeeds.
7701 Redo calculations to avoid overflow.
7702 * keyboard.h: Change prototypes to match the above.
7704 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

7712 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7714 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7715 Now ptrdiff_t, not int.
7716 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
7717 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
7719 * process.c (Fnetwork_interface_list): Check for overflow
7720 in size calculation.
7722 * region-cache.c (move_cache_gap): Check for size calculation overflow.

7725 overflow. Don't bother calling xmalloc when xrealloc will do.
7727 * search.c (Freplace_match): Check for size calculation overflow.
7728 (Fset_match_data): Don't assume list lengths fit in 'int'.
7730 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7731 for command line length. Do not attempt to address one before the
7732 beginning of an array, as that's not portable.
7734 * term.c (max_frame_lines): Remove; unused.
7735 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7737 (encode_terminal_code, calculate_costs): Check for size
7738 calculation overflow.
7739 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
7740 table lengths and related sizes. Don't update size until alloc
7741 done. Redo calculations to avoid overflow.

7744 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
7745 subtracting pointers.

7750 Don't update size until alloc done.
7751 Redo size calculations to avoid overflow.

7753 (main) [DEBUG]: Fix typo in invoking tparam1.
7755 * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
7756 Use ptrdiff_t, not int, for sizes.
7757 (store_mode_line_noprop_char): Don't update size until alloc done.
7759 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
7760 Use ptrdiff_t, not int, for sizes.
7761 (Finternal_make_lisp_face, cache_face):
7762 Check for size calculation overflow.
7763 (cache_face): Treat size calculation overflows as if they were
7764 memory exhaustion (the usual treatment), rather than aborting.
7766 * xfns.c (x_encode_text, x_set_name_internal)
7767 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7768 sizes, since they can exceed INT_MAX in size. Check for size
7769 calculation overflow.
7771 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
7772 (xg_select): Check for size calculation overflow.
7773 Don't update size until alloc done.
7775 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7776 as sprintf is limited to int lengths.
7778 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7779 (X_LONG_MIN): New macros.
7780 Use them to make the following changes clearer.
7781 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7782 This change doesn't affect the value now, but it may help remind
7783 future maintainers not to raise the value too much later.
7784 (SELECTION_QUANTUM): Remove, replacing with ...
7785 (selection_quantum): ... new function, which avoids overflow.
7787 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7788 assumption that selection length fits in 'int'.
7789 (x_reply_selection_request, x_handle_selection_request)
7790 (x_get_window_property, receive_incremental_selection)
7791 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7792 (lisp_data_to_selection_data, clean_local_selection_data):
7793 Use ptrdiff_t, not int, to record length of selection.
7794 (x_reply_selection_request, x_get_window_property)
7795 (receive_incremental_selection, x_property_data_to_lisp):
7796 Redo calculations to avoid overflow.
7797 (x_reply_selection_request): When sending hint, ceiling it at
7798 X_LONG_MAX rather than relying on wraparound overflow to send
7800 (x_get_window_property, receive_incremental_selection)
7801 (lisp_data_to_selection_data, x_property_data_to_lisp):
7802 Check for size-calculation overflow.
7803 (x_get_window_property, receive_incremental_selection)

7805 Don't store size until memory allocation succeeds.
7806 (x_get_window_property): Plug memory leak on memory exhaustion.
7807 Don't double-block input; malloc is safe here. Don't assume 2**34
7808 - 4 fits in unsigned long. Add an xassert to check
7809 XGetWindowProperty overflow. Be more careful about overflow
7810 calculations, and distinguish size from memory overflow better.
7811 (receive_incremental_selection): When tracing, don't assume
7812 unsigned int is less than INT_MAX.
7813 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7814 harmful) conversions of unsigned short to int.
7815 (lisp_data_to_selection_data): Don't assume that integers
7816 in the range -65535 through -1 fit in an X unsigned short.
7817 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7818 result parameters unless successful. Rely on cons_to_unsigned
7819 to report problems with elements; the old code wasn't right anyway.
7820 (x_check_property_data): Check for int overflow; we cannot use
7821 a wider type due to X limits.
7822 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7824 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7826 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7827 (x_term_init): Check for size calculation overflow.
7828 (x_color_cells): Don't store size until memory allocation succeeds.
7829 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
7830 Don't assume alloca size is less than MAX_ALLOCA.

7834 Use ptrdiff_t for composition IDs.
7835 * character.c (lisp_string_width):
7836 * composite.c (composition_table_size, n_compositions)
7837 (get_composition_id, composition_gstring_from_id):
7838 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
7839 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
7840 * window.c (Frecenter):
7841 Use ptrdiff_t, not int, for composition IDs.
7842 * composite.c (get_composition_id): Check for integer overflow.
7843 * composite.h: Adjust prototypes to match the above changes.
7845 Use ptrdiff_t for hash table indexes.
7846 * category.c (hash_get_category_set):
7847 * ccl.c (ccl_driver):
7848 * charset.h (struct charset.hash_index, CHECK_CHARSET_GET_ID):

7853 * image.c (xpm_get_color_table_h):
7854 * lisp.h (hash_lookup, hash_put):
7855 * minibuf.c (Ftest_completion):
7856 Use ptrdiff_t for hash table indexes, not int (which is too
7857 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7858 32-bit --with-wide-int hosts).
7860 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7861 Add a FIXME comment about memory leaks.
7862 (syms_of_charset): Don't assume xmalloc returns.
7864 Don't assume that stated character widths fit in int.
7865 * character.c (Fchar_width, c_string_width, lisp_string_width):
7866 * character.h (CHAR_WIDTH):
7867 * indent.c (MULTIBYTE_BYTES_WIDTH):
7868 Use sanitize_char_width to avoid undefined and/or bad behavior
7869 with outlandish widths.
7870 * character.h (sanitize_tab_width): Rename from sanitize_width,
7871 now that we have two such functions. All uses changed.
7872 (sanitize_char_width): New inline function.
7874 Don't assume that tab-width fits in int.
7875 * character.h (sanitize_width): New inline function.
7876 (SANE_TAB_WIDTH): New macro.
7877 (ASCII_CHAR_WIDTH): Use it.
7878 * indent.c (sane_tab_width): Remove. All uses replaced by
7879 SANE_TAB_WIDTH (current_buffer).
7880 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
7882 * fileio.c: Integer overflow issues with file modes.
7883 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7885 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
7886 Remove unreachable code.

7889 * xterm.c: Don't go over XClientMessageEvent limit.
7890 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7891 (x_send_scroll_bar_event): Likewise. Check that the size does not
7892 exceed limits imposed by XClientMessageEvent, as well as the usual
7893 ptrdiff_t and size_t limits.
7895 * keyboard.c: Overflow, signedness and related fixes.
7896 (make_lispy_movement): Use same integer type in forward decl
7897 that is used in the definition.
7898 (read_key_sequence, keyremap_step):
7899 Change bufsize argument back to int, undoing my 2011-03-30 change.
7900 We prefer signed types, and int is wide enough here.
7901 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7902 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7903 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7904 length, not size_t. Use ptrdiff_t for index, not int.
7905 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7906 possibility of integer overflow.
7908 Overflow, signedness and related fixes for images.
7910 * dispextern.h (struct it.stack[0].u.image.image_id)
7911 (struct_it.image_id, struct image.id, struct image_cache.size)
7912 (struct image_cache.used, struct image_cache.ref_count):

7917 * nsmenu.m (update_frame_tool_bar):
7918 * xdisp.c (calc_pixel_width_or_height):
7919 * xfns.c (image_cache_refcount):
7920 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7921 on typical 64-bit hosts.
7923 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7924 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7925 Omit unnecessary casts to int.

7927 when the callers expect that.
7928 (image_ascent): Redo ascent calculation to avoid int overflow.
7929 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7930 (lookup_image): Remove unnecessary tests.
7931 (xbm_image_p): Locals are now of int, not EMACS_INT,
7932 since parse_image_check makes sure they fit into int.
7933 (png_load, gif_load, svg_load_image):
7934 Prefer int to unsigned where either will do.
7935 (tiff_handler): New function, combining the cores of the
7936 old tiff_error_handler and tiff_warning_handler.
7937 This function is rewritten to use vsnprintf and thereby avoid
7938 stack buffer overflows. It uses only the features of vsnprintf
7939 that are common to both POSIX and native Microsoft.
7940 (tiff_error_handler, tiff_warning_handler): Use it.
7941 (tiff_load, gif_load, imagemagick_load_image):
7942 Don't assume :index value fits in 'int'.
7943 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7944 (imagemagick_load_image): Check that crop parameters fit into
7945 the integer types that MagickCropImage accepts. Don't assume
7946 Vimagemagick_render_type has a nonnegative value. Don't assume
7947 size_t fits in 'long'.
7948 (gs_load): Use printmax_t to print the widest integers possible.
7949 Check for integer overflow when computing image height and width.
7951 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7953 * xdisp.c (redisplay_window): Don't force window start if point
7954 will be invisible in the resulting window. (Bug#9324)
7956 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7958 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7959 the display spec is of the form `(space ...)'.
7960 (handle_display_spec): Return the value returned by
7961 handle_single_display_spec, not just 1 or zero.
7962 (handle_single_display_spec): If the display spec is of the form
7963 `(space ...)', and specifies display in the text area, return 2
7965 (try_cursor_movement): Check for the need to scroll more
7966 accurately, and prefer exact match for point under bidi.
7967 Don't advance `row' beyond the last row of the window.
7969 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7970 into disp_prop; all users changed.
7972 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7973 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7974 for the text covered by the display property.
7976 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7978 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7982 2011-08-24 Eli Zaretskii <eliz@gnu.org>
7984 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7985 buffers, return left-to-right.
7986 (set_cursor_from_row): Consider candidate row a win if its glyph
7987 represents a newline and point is on that newline. Fixes cursor
7988 positioning on the newline at EOL of R2L text within L2R
7989 paragraph, and vice versa.
7990 (try_cursor_movement): Check continued rows, in addition to
7991 continuation rows. Fixes unwarranted scroll when point enters a
7992 continued line of R2L text within an L2R paragraph, or vice versa.
7993 (cursor_row_p): Consider the case of point being equal to
7994 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7995 from the end of a short line to the beginning of a continued line
7996 of R2L text within L2R paragraph.
7997 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7998 composed characters.
8000 * bidi.c (bidi_check_type): Use xassert.
8001 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8004 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8006 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
8009 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8011 * nsfont.m (ns_otf_to_script): Fix typo.
8013 2011-08-22 Kenichi Handa <handa@m17n.org>
8015 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8016 extra slot even if the purpose is char-code-property-table.
8018 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8020 * xdisp.c (redisplay_window): When computing centering_position,
8021 account for the height of the header line. (Bug#8874)
8023 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8024 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8025 candidate is selected by the mouse, and that candidate has a
8026 composed character under the mouse.
8028 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8029 coordinates reported by pos-visible-in-window-p for a composed
8030 character in column zero.
8032 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8034 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8036 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8038 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8039 consider it a hit if to_charpos is anywhere in the range of the
8040 composed buffer positions.
8042 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8044 * image.c (gif_load): Don't assume that each subimage has the same
8045 dimensions as the base image. Handle disposal method that is
8046 "undefined" by the gif spec (Bug#9335).
8048 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8050 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8051 (Fcondition_case): Document `debug' symbol in error handler.
8053 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8055 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8056 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8057 from an Org mode buffer to a Speedbar frame.
8059 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8060 a composition, take its buffer position from IT->cmp_it.charpos.
8061 Fixes cursor positioning at the beginning of a line that begins
8062 with a composed character.
8064 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8066 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8067 character bidirectional type, use STRONG_L instead. Fixes crashes
8068 in a buffer produced by `describe-categories'.
8070 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8071 members before the level stack, so they would be saved and
8072 restored when copying iterator state. Fixes incorrect reordering
8073 around TABs covered by display properties.
8075 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8077 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8079 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8081 * eval.c (internal_condition_case, internal_condition_case_1)
8082 (internal_condition_case_2, internal_condition_case_n):
8083 Remove unnecessary aborts (Bug#9081).
8085 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8087 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8088 has no `load' handler, try opening the file locally. (Bug#9311)
8090 2011-08-16 Ken Brown <kbrown@cornell.edu>
8092 * gmalloc.c: Expand comment.
8094 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8096 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8097 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8099 2011-08-16 Ken Brown <kbrown@cornell.edu>
8101 Fix memory allocation problems in Cygwin build (Bug#9273).
8103 * unexcw.c ( __malloc_initialized): Declare external variable.
8104 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8106 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8108 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8110 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8112 [CYGWIN] (special_realloc): New function.
8113 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8114 requests to realloc storage in the static heap.
8116 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8118 * bidi.c (bidi_initialize): Remove unused local.

8123 * biditype.h: Remove file.
8124 * makefile.w32-in ($(BLD)/bidi.$(O)):
8125 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8127 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8129 * chartab.c: Improve commentary for the uniprop_table API.
8131 * bidi.c (bidi_paragraph_init): Support zero value of
8132 bidi_ignore_explicit_marks_for_paragraph_level.
8133 (bidi_initialize): Use uniprop_table instead of including
8134 biditype.h and bidimirror.h.
8136 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8137 coordinates of the iterator when restoring from ppos_it.
8140 2011-08-14 Kenichi Handa <handa@m17n.org>
8142 * process.c (create_process): Call setup_process_coding_systems
8143 after the pid of the process is set to -1 (Bug#8162).
8145 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8147 * xdisp.c (move_it_in_display_line_to): Don't invoke
8148 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8149 ppos_it. Fixes vertical cursor motion when line beginning is
8150 covered by an image. (Bug#9296)
8152 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8154 * nsterm.h (ns_run_ascript): Declare.
8155 (NSAPP_DATA2_RUNASSCRIPT): Define.
8157 * nsfns.m (as_script, as_result, as_status): New static variables.
8158 (ns_run_ascript): New function.
8159 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8160 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8161 the event loop. Get status from as_status (Bug#7276).
8163 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8164 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8165 the event loop (Bug#7276).
8167 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8169 * gnutls.c (QCgnutls_bootprop_priority)
8170 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8171 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8172 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8173 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8174 (QCgnutls_bootprop_verify_hostname_error)
8175 (QCgnutls_bootprop_callbacks_verify): Rename from
8176 Qgnutls_bootprop_..., all uses changed.
8178 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8181 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8183 * xfaces.c (Qframe_set_background_mode): Now static.
8184 * dispextern.h (Qframe_set_background_mode): Remove decl.
8186 * process.c (Fnetwork_interface_info): Declare local only if needed.
8188 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8190 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8191 (Fnetwork_interface_list): Allocate in increments of bytes instead
8192 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8193 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8195 (struct ifflag_def): notrailers is smart on OSX.
8196 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8197 Get hardware address with getifaddrs if available.
8199 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8201 * xdisp.c (iterate_out_of_display_property): xassert that
8202 IT->position is set to within IT->object's boundaries. Break from
8203 the loop as soon as EOB is reached; avoids infloops in redisplay
8204 when IT->position is set up wrongly due to some bug.
8205 Set IT->current to match the bidi iterator unconditionally.
8206 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8207 entry. Force push_it to save on the stack the current
8208 buffer/string position, to be restored by pop_it. Fix flags in
8209 the iterator structure wrt the object coming from a display
8210 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8211 properties. (Bug#9284)
8213 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8215 * fontset.c (fontset_get_font_group): Add proper type checks.

8225 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8227 * xdisp.c (forward_to_next_line_start): Allow to use the
8228 no-display-properties-and-no-overlays under bidi display.
8229 Set disp_pos in the bidi iterator to avoid searches for display
8230 properties and overlays.
8232 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8234 * editfns.c (Fset_time_zone_rule): Document relationship with the
8237 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8238 the font entity extracted from the cache (Bug#8109).
8240 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8242 * composite.c (autocmp_chars): Don't reset point. That is done by
8243 restore_point_unwind (Bug#5984).
8245 2011-08-07 Juri Linkov <juri@jurta.org>
8247 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8248 to show the arg `TIME' instead of `TIMEVAL'.
8250 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8252 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8253 display property strides EOL and includes a newline, as in
8254 longlines-mode. (Bug#9254)
8255 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8256 word-wrap under bidirectional display. (Bug#9224)
8258 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8259 is non-zero, even if the data buffer is NULL. Fixes a crash in
8260 vertical-motion with longlines-mode. (Bug#9254)
8262 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8264 * bidi.c <bidi_cache_total_alloc>: Now static.
8265 (bidi_initialize): Initialize bidi_cache_total_alloc.
8267 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8270 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8271 amount allocated this far in `bidi_cache_total_alloc'.
8272 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8273 non-zero, only free the data buffer without restoring the cache
8274 contents. All callers changed.
8276 * dispextern.h (bidi_unshelve_cache): Update prototype.
8278 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8279 (move_it_in_display_line, move_it_to)
8280 (move_it_vertically_backward, move_it_by_lines): Replace the call
8281 to xfree to an equivalent call to bidi_unshelve_cache.
8282 (move_it_in_display_line_to): Fix logic of returning
8283 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8285 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8287 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8288 came from a string character with a `cursor' property. (Bug#9229)
8290 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8292 * Makefile.in (LIB_PTHREAD): New variable.
8293 (LIBES): Add LIB_PTHREAD (Bug#9216).
8295 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8296 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8298 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8300 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8302 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8304 * xterm.c (x_find_topmost_parent): New function.
8305 (x_set_frame_alpha): Find topmost parent window with
8306 x_find_topmost_parent and set the property there also (bug#9181).
8307 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8309 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8311 * callproc.c (Fcall_process): Avoid vfork clobbering
8312 the local vars buffer, coding_systems, current_dir.
8314 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8316 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8318 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8320 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8321 so that it is not optimized away.
8323 * xdisp.c (compute_display_string_pos): Remove unused local.
8325 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8327 Fix slow cursor motion and scrolling in large buffers with
8328 selective display, like Org Mode buffers. (Bug#9218)
8330 * dispextern.h (struct bidi_it): New member disp_prop_p.
8332 * xdisp.c: Remove one-slot cache of display string positions.
8333 (compute_display_string_pos): Accept an additional argument
8334 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8335 for a display string or property. If found, set DISP_PROP_P
8338 * bidi.c (bidi_fetch_char): Accept an additional argument
8339 DISP_PROP_P, and pass it to compute_display_string_pos.
8340 Only handle text covered by a display string if DISP_PROP_P is returned
8341 non-zero. All callers of bidi_fetch_char changed.
8343 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8345 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8347 2010-12-03 Don March <don@ohspite.net>
8349 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8350 last character M-[char] is translated to ESC [char] (bug#7541).
8352 2011-08-02 Kenichi Handa <handa@m17n.org>
8354 * lisp.h (uniprop_table): Extern it.
8356 * chartab.c (uniprop_table): Make it non-static.
8358 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8360 * xdisp.c (forward_to_next_line_start): Accept additional argument
8361 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8363 (reseat_at_next_visible_line_start): Use the bidi iterator state
8364 returned by forward_to_next_line_start to restore the state of
8365 it->bidi_it after backing up to previous newline. (Bug#9212)
8367 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8369 * regex.c (re_comp): Protoize.
8370 (re_exec): Fix return type.
8371 (regexec): Fix type of `ret'. (Bug#9203)
8373 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8375 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8376 This is needed if max-image-size is a floating-point number.
8378 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8380 * print.c (print_object): Print empty symbol as ##.
8382 * lread.c (read1): Read ## as empty symbol.
8384 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8386 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8387 setting frame foreground color (Bug#9175).
8388 (x_set_background_color): Likewise.
8390 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8391 contents (Bug#9176).
8392 (EmacsTooltip -init): Remove bezels and add shadows to
8395 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8396 or scroll bar (Bug#8470).
8398 * nsfont.m (nsfont_open): Remove assignment to voffset and
8399 unnecessary vars hshink, expand, hd, full_height, min_height.
8400 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8402 * nsterm.h (nsfont_info): Remove voffset field.
8404 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8406 Implement strike-through and overline on NextStep (Bug#8863).
8408 * nsfont.m (nsfont_open): Use underline position provided by font,
8409 instead of hard-coded value of 2.
8410 (nsfont_draw): Call ns_draw_text_decoration instead.
8412 * nsterm.h: Add declaration for ns_draw_text_decoration.
8414 * nsterm.m (ns_draw_text_decoration): New function for drawing
8415 underline, overline, and strike-through.
8416 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8417 ns_draw_text_decoration. Change treatment of cursor drawing to
8418 accommodate underlining, etc.
8420 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8422 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8425 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8427 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8428 Without this fix, if a signal arrives just after memory fills up,
8429 'malloc' might be invoked reentrantly.
8431 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8432 In other words, assume that every image size is allowed, on non-X
8433 hosts. This assumption is probably wrong, but it lets Emacs compile.
8435 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8437 * regex.c (re_iswctype): Convert return values to boolean.
8439 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8441 * xdisp.c (compute_display_string_pos): Don't use cached display
8442 string position if the buffer had its restriction changed.
8445 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8447 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8449 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8451 Integer signedness and overflow and related fixes. (Bug#9079)
8453 * bidi.c: Integer size and overflow fixes.
8454 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8455 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8456 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8457 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8458 (bidi_find_other_level_edge):
8459 Use ptrdiff_t instead of EMACS_INT where either will do.
8460 This works better on 32-bit hosts configured --with-wide-int.
8461 (bidi_cache_ensure_space): Check for size-calculation overflow.
8462 Use % rather than repeated addition, for better worst-case speed.
8463 Don't set bidi_cache_size until after xrealloc returns, because it
8465 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8466 (bidi_cache_ensure_space): Also check that the bidi cache size
8467 does not exceed that of the largest Lisp string or buffer. See Eli
8468 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8470 * alloc.c (__malloc_size_t): Remove.
8471 All uses replaced by size_t. See Andreas Schwab's note
8472 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8474 * image.c: Improve checking for integer overflow.
8475 (check_image_size): Assume that f is nonnull, since
8476 it is always nonnull in practice. This is one less thing to
8477 worry about when checking for integer overflow later.
8478 (x_check_image_size): New function, which checks for integer
8479 overflow issues inside X.
8480 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8481 This removes the need for a memory_full check.
8482 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8483 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8484 (xbm_read_bitmap_data): Change locals back to 'int', since
8485 their values must fit in 'int'.
8486 (xpm_load_image, png_load, tiff_load):
8487 Invoke x_create_x_image_and_pixmap earlier,
8488 to avoid much needless work if the image is too large.
8489 (tiff_load): Treat overly large images as if
8490 x_create_x_image_and_pixmap failed, not as malloc failures.
8491 (gs_load): Use x_check_image_size.
8493 * gtkutil.c: Omit integer casts.
8494 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8495 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8497 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8499 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8500 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8501 would wrongly return t on a 64-bit host.
8503 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8504 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8505 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8506 and therefore cause GCC to emit a bogus diagnostic in some cases.
8508 * image.c: Integer signedness and overflow and related fixes.
8509 This is not an exhaustive set of fixes, but it's time to
8510 record what I've got.
8511 (lookup_pixel_color, check_image_size): Remove redundant decls.
8512 (check_image_size): Don't assume that arbitrary EMACS_INT values
8513 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8514 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8515 (tiff_load, imagemagick_load_image):
8516 Check for overflow in size calculations.
8517 (x_create_x_image_and_pixmap): Remove unnecessary test for
8518 xmalloc returning NULL; that can't happen.
8519 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8520 (xpm_color_bucket): Use better integer hashing function.
8521 (xpm_cache_color): Don't possibly over-allocate memory.
8522 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8523 (gif_memory_source):
8524 Use ptrdiff_t, not int or size_t, to record sizes.
8525 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8526 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8527 either works, as we prefer signed integers.
8528 (tiff_read_from_memory, tiff_write_from_memory):
8529 Return tsize_t, not size_t, since that's what the TIFF API wants.
8530 (tiff_read_from_memory): Don't fail simply because the read would
8531 go past EOF; instead, return a short read.
8532 (tiff_load): Omit no-longer-needed casts.
8533 (Fimagemagick_types): Don't assume size fits into 'int'.
8535 Improve hashing quality when configured --with-wide-int.
8536 * fns.c (hash_string): New function, taken from sxhash_string.
8537 Do not discard information about ASCII character case; this
8538 discarding is no longer needed.
8539 (sxhash-string): Use it. Change sig to match it. Caller changed.
8540 * lisp.h: Declare it.
8541 * lread.c (hash_string): Remove, since we now use fns.c's version.
8542 The fns.c version returns a wider integer if --with-wide-int is
8543 specified, so this should help the quality of the hashing a bit.
8545 * emacs.c: Integer overflow minor fix.
8546 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8547 Define only if GNU_LINUX.
8548 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8550 * dispnew.c: Integer signedness and overflow fixes.
8551 Remove unnecessary forward decls, that were a maintenance hassle.
8552 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8554 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8555 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8556 (prepare_desired_row, line_draw_cost):
8557 Use int, not unsigned, where either works.
8558 (save_current_matrix, restore_current_matrix):
8559 Use ptrdiff_t, not size_t, where either works.
8560 (init_display): Check for overflow more accurately, and without
8561 relying on undefined behavior.
8563 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8564 Remove, replacing with the new symbols in lisp.h. All uses changed.
8565 * fileio.c (make_temp_name):
8566 * filelock.c (lock_file_1, lock_file):
8567 * xdisp.c (message_dolog):
8568 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8569 Use pMd etc. instead.
8570 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8571 replacing the pWIDE etc. symbols removed from editfns.c.
8573 * keyboard.h (num_input_events): Now uintmax_t.
8574 This is (very slightly) less likely to mess up due to wraparound.
8577 * buffer.c: Integer signedness fixes.
8578 (alloc_buffer_text, enlarge_buffer_text):
8579 Use ptrdiff_t rather than size_t when either will do, as we prefer
8582 * alloc.c: Integer signedness and overflow fixes.
8583 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8584 (__malloc_size_t): Default to size_t, not to int.
8585 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8586 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8587 Prefer ptrdiff_t to size_t when either would do, as we prefer
8589 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8590 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8591 Now const. Initialize with values that are in range even if char
8593 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8594 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8595 These functions do the right thing with sizes > 2**32.
8596 (check_depth): Now ptrdiff_t, not int.
8597 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8598 Adjust to new way of storing sizes. Check for size overflow bugs
8600 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8601 slightly wrong anyway, as it missed one instance of
8602 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8603 (refill_memory_reserve): Omit needless cast to size_t.
8604 (mark_object_loop_halt): Mark as externally visible.
8606 * xselect.c: Integer signedness and overflow fixes.
8607 (Fx_register_dnd_atom, x_handle_dnd_message):
8608 Use ptrdiff_t, not size_t, since we prefer signed.
8609 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8610 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8611 x_dnd_atoms_size and x_dnd_atoms_length.
8613 * doprnt.c: Prefer signed to unsigned when either works.
8615 * doprnt.c (doprnt):
8617 * xdisp.c (vmessage):
8618 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8619 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8620 prefer signed arithmetic to avoid comparison confusion.
8621 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8622 but is a bit tricky.
8624 Assume freestanding C89 headers, string.h, stdlib.h.
8625 * data.c, doprnt.c, floatfns.c, print.c:
8626 Include float.h unconditionally.
8627 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8628 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8629 * regex.c: Likewise for stddef.h, string.h.
8630 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8631 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8632 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8633 (STDC_HEADERS): Remove obsolete defines.
8634 * sysdep.c: Include limits.h unconditionally.
8636 Assume support for memcmp, memcpy, memmove, memset.
8637 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8638 * regex.c (memcmp, memcpy):
8639 Remove; we assume C89 now.
8641 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8642 (__malloc_safe_bcopy): Remove; no longer needed.
8644 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8645 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8646 well either way, and we prefer signed to unsigned.
8648 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8650 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8651 closes the connection while we're reading (bug#9182).
8653 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8655 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8656 are specified (Bug#9168).
8658 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8660 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8661 Found by GCC static checking and --with-wide-int on a 32-bit host.
8663 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8665 * xdisp.c (compute_display_string_pos): Fix logic of caching
8666 previous display string position. Initialize cached_prev_pos to
8667 -1. Fixes slow-down at the beginning of a buffer.
8669 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8671 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8672 for attrs[LFACE_FONTSET_INDEX].
8674 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8676 * xml.c (parse_region): Remove unused local
8677 that was recently introduced.
8679 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8681 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8682 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8684 * xdisp.c (move_it_in_display_line_to): Record the best matching
8685 position for TO_CHARPOS while scanning the line, and restore it on
8686 exit if none of the characters scanned was an exact match.
8687 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8688 when exact match is impossible due to invisible text, and the
8689 lines are truncated.
8691 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8693 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8696 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8698 Fix a significant slow-down of cursor motion with C-n, C-p,
8699 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8700 auto-repeat under bidi redisplay in fontified buffers.
8701 * xdisp.c (compute_stop_pos_backwards): New function.
8702 (next_element_from_buffer): Call compute_stop_pos_backwards to
8703 find a suitable prev_stop when we find ourselves before
8705 (reseat): Don't look for prev_stop, as that could mean a very long
8707 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8708 <cached_disp_overlay_modiff>: Cache for last found display string
8710 (compute_display_string_pos): Return the cached position if asked
8711 about the same buffer in the same area of character positions, and
8712 the buffer wasn't changed since the time the display string
8713 position was cached.
8715 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8717 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8718 is an integer, which is important for empty lines. (Bug#9149)
8720 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8722 * frame.c (Fmodify_frame_parameters): In tty case, update the
8723 default face if necessary (Bug#4238).
8725 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8727 * editfns.c (Fstring_to_char): No need to explain what a character
8728 is in the docstring (Bug#6576).
8730 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8732 * xml.c (parse_region): Make sure we always return a tree.
8734 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8736 * xml.c (parse_region): If a document contains only comments,
8739 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8741 * xml.c (make_dom): Return comments, too.
8743 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8746 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8747 and the surrounding thread.
8748 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8749 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8750 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8752 * s/openbsd.h (BROKEN_SIGIO): Define.
8753 * unexelf.c (unexec) [__OpenBSD__]:
8754 Don't update the .mdebug section of the Alpha COFF symbol table.
8756 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8758 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8761 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8763 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8764 This fixes some race conditions on the permissions of any newly
8767 * alloc.c (valid_pointer_p): Use pipe, not open.
8768 This fixes some permissions issues when debugging.
8770 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8771 If fchown fails to set both uid and gid, try to set just gid,
8772 as that is sometimes allowed. Adjust the file's mode to eliminate
8773 setuid or setgid bits that are inappropriate if fchown fails.
8775 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8777 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8778 to compare Lisp_Objects.
8779 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8780 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8781 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8783 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8785 * lread.c (read_integer): Unread even EOF character.

8788 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8789 symbol character follows.
8791 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8793 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8794 This works around a problem with the previous change to Fcopy_file.
8795 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8796 and without this change, GCC might complain about discarding
8797 fchown's return value.
8799 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8801 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8803 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8805 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8807 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8809 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8810 it's used from the C level.
8812 * process.c: Use the same condition for POLL_FOR_INPUT in both
8813 keyboard.c and process.c (bug#1858).
8815 2011-07-09 Lawrence Mitchell <wence@gmx.li>

8818 (Fgnutls_boot): Use it.
8820 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8822 * doc.c (Fsubstitute_command_keys): Revert last change.
8824 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8826 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8827 quotes the next character, and doesn't affect other longer
8828 sequences (bug#8935).
8830 * lread.c (syms_of_lread): Clarify that is isn't only
8831 `eval-buffer' and `eval-defun' that's affected by
8832 `lexical-binding' (bug#8460).
8834 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8836 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8837 bidi redisplay when a line includes both an image and is truncated.
8839 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8841 Fix minor problems found by static checking.
8842 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8843 (elsz): Now a signed constant, not a size_t var. We prefer signed
8844 types to unsigned, to avoid integer comparison confusion. Without
8845 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8846 "cannot optimize loop, the loop counter may overflow", a symptom
8848 * indent.c (Fvertical_motion): Mark locals as initialized.
8849 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8851 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8853 * search.c (Fre_search_backward): Mention `case-fold-search' in
8854 all the re_search_* functions (bug#8138).
8856 * keyboard.c (Fopen_dribble_file): Document when the file is

8872 Initialize itb.string.lstring.
8873 (init_iterator): Call bidi_init_it only of a valid
8874 buffer position was specified. Initialize paragraph_embedding to
8876 (reseat_to_string): Initialize the bidi iterator.
8877 (display_string): If we need to ignore text properties of
8878 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8879 original value of -1 will not work with bidi.)

8883 (compute_display_string_end): Support display properties on Lisp
8885 (init_iterator, reseat_1, reseat_to_string): Initialize the
8886 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8887 when iterating on a string not from display properties).
8888 (compute_display_string_pos, compute_display_string_end):
8889 Fix calculation of the object to scan. Fixes an error when using
8891 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8892 base_level_stop; instead, set base_level_stop to BEGV.
8893 Fixes crashes in vertical-motion.
8894 (next_element_from_buffer): Improve commentary for when
8895 the iterator is before prev_stop.
8896 (init_iterator): Initialize bidi_p from the default value of
8897 bidi-display-reordering, not from buffer-local value. Use the
8898 buffer-local value only if initializing for buffer iteration.
8899 (handle_invisible_prop): Support invisible properties on strings
8900 that are being bidi-reordered.
8901 (set_iterator_to_next): Support bidi reordering of C strings and

8918 (get_visually_first_element): New function, refactored from common
8919 parts of next_element_from_buffer, next_element_from_string, and
8920 next_element_from_c_string.
8921 (tool_bar_lines_needed, redisplay_tool_bar)
8922 (display_menu_bar): Force left-to-right direction. Add a FIXME
8923 comment for making that be controlled by a user option.

8937 pushed the iterator stack, restore the internal state of the bidi
8938 iterator by calling bidi_pop_it same number of times.
8939 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8940 and we are bidi-iterating, don't decrement the iterator position;
8941 instead, set the first_elt flag in the bidi iterator, to produce
8943 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8944 (push_display_prop): xassert that we are iterating a buffer.
8945 (push_it, pop_it): Save and restore paragraph_embedding member.

8954 from_disp_prop_p flag.
8955 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

8977 (back_to_previous_visible_line_start, reseat_1)
8978 (init_iterator): Empty the bidi cache "stack".
8979 (move_it_in_display_line_to): If iterator ended up at

9002 (bidi_move_to_visually_next): Compare cache index with
9003 bidi_cache_start rather than with zero.
9004 (bidi_fetch_char): Accept new argument STRING; all callers
9005 changed. Support iteration over a string. Support strings with
9006 display properties. Support unibyte strings. Fix the type of
9007 `len' according to what STRING_CHAR_AND_LENGTH expects.
9008 (bidi_paragraph_init, bidi_resolve_explicit_1)

9106 The old code sometimes used this field without initializing it.
9108 * alloc.c (gc_sweep): Don't read past end of array.

9114 * character.c (Fcharacterp): Don't advertise optional ignored
9115 argument. (Bug#4026)

9414 Random fixes. E.g., (random) never returned negative values.
9415 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9416 subseconds part to the entropy, as that's a bit more random.
9417 Prefer signed to unsigned, since the signedness doesn't matter and
9418 in general we prefer signed. When given a limit, use a
9419 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9420 latter isn't right if USE_2_TAGS_FOR_INTS.
9421 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9422 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9434 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9435 This is more efficient than Ffile_directory_p and avoids a minor race.
9437 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9439 * buffer.c (Foverlay_put): Say what the return value is
9442 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9443 is a directory before asking whether to use the file name
9445 (barf_or_query_if_file_exists): Make the "File is a directory"
9446 error be more correct.
9448 * fns.c (Frequire): Remove the mention of the .gz files, since
9449 that's installation-specific, but keep the mention of
9450 `get-load-suffixes'.
9452 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9454 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9465 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9529 (syms_of_keymap): Defsubr make-composed-keymap.
9530 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

9533 2011-07-01 Glenn Morris <rgm@gnu.org>
9535 * Makefile.in (SETTINGS_LIBS): Fix typo.

9565 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9567 * eval.c (struct backtrace): Simplify and port the data structure.
9568 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9569 signed bit field, as this assumption is not portable and it makes
9570 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9571 "char debug_on_exit : 1" as this is not portable either; instead,
9572 use the portable "unsigned int debug_on_exit : 1". Remove unused
9573 member evalargs. Remove obsolete comments about cc bombing out.
9575 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9743 Don't set size unless allocation succeeds.
9745 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9746 for sizes. Check for string overflow more accurately.

9759 * lread.c: Integer overflow fixes.
9760 (read_integer): Radix is now EMACS_INT, not int,
9761 to improve quality of diagnostics for out-of-range radices.
9762 Calculate buffer size correctly for out-of-range radices.
9763 (read1): Check for integer overflow in radices, and in
9764 read-circle numbers.

9781 (read_escape): Check for hex character overflow.
9783 2011-06-22 Leo Liu <sdl.web@gmail.com>
9785 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9786 Move to minibuffer.el.
9788 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9790 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9791 The following patches are for when GLYPH_DEBUG && !XASSERT.
9792 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9793 * dispnew.c (flush_stdout):
9794 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9795 Mark as externally visible.
9796 * dispnew.c (check_window_matrix_pointers): Now static.
9797 * dispnew.c (window_to_frame_vpos):
9798 * xfns.c (unwind_create_frame):
9799 * xterm.c (x_check_font): Remove unused local.
9800 * scroll.c (CHECK_BOUNDS):

9805 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9807 (debug_method_add): Use va_list and vsprintf rather than relying
9808 on undefined behavior with wrong number of arguments.
9809 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9810 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9811 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9812 since we're not interested in debugging glyphs with old libraries.
9813 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9814 GCC 4.6.0's static checking.
9816 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9818 Integer overflow and signedness fixes (Bug#8873).

9835 (.bitmaps_last, struct x_output.icon_bitmap):
9836 Use ptrdiff_t, not int, for bitmap indexes.
9837 (x_allocate_bitmap_record): Check for size overflow.

9840 Use ptrdiff_t, not int, for overlay counts.
9841 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9842 * editfns.c (overlays_around, get_pos_property):

9845 * xfaces.c (face_at_buffer_position):
9846 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9847 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9848 (Fnext_overlay_change, Fprevious_overlay_change)
9849 (mouse_face_overlay_overlaps, Foverlays_in):
9850 Use ptrdiff_t, not int, for sizes.
9851 (overlays_at, overlays_in): Check for size-calculation overflow.
9853 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9855 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9856 (x_session_initialize): Do not assume string length fits in int.
9858 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9859 This is unlikely, but can occur if DPI is outlandish.
9861 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9862 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9864 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9865 * xrdb.c (magic_file_p, search_magic_path):
9866 Omit last arg SUFFIX; it was always 0. All callers changed.

9875 not unsigned long, as we prefer signed integers. All callers changed.
9876 Detect integer overflow in repeat count.
9877 (message_dolog): Don't assume print length fits in 39 bytes.
9878 (display_mode_element): Don't assume strlen fits in int.
9880 * termcap.c: Don't assume sizes fit in int and never overflow.
9881 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9882 (gobble_line): Check for size-calculation overflow.
9884 * minibuf.c (Fread_buffer):

9899 * filelock.c: Fix some buffer overrun and integer overflow issues.
9900 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9901 Reformulate so as not to need the command string.
9902 Invoke gzip -cd rather than gunzip, as it's more portable.
9903 (lock_info_type, lock_file_1, lock_file):
9904 Don't assume pid_t and time_t fit in unsigned long.
9905 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9906 (current_lock_owner): Prefer signed type for sizes.
9907 Use memcpy, not strncpy, where memcpy is what is really wanted.
9908 Don't assume (via atoi) that time_t and pid_t fit in int.
9909 Check for time_t and/or pid_t out of range, e.g., via a network share.
9910 Don't alloca where an auto var works fine.
9912 * fileio.c: Fix some integer overflow issues.
9913 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9914 Don't assume string length fits in int.
9915 (directory_file_name): Don't assume string length fits in long.

9937 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9939 * lread.c (invalid_syntax): Omit length argument.
9940 All uses changed. This doesn't fix a bug, but it simplifies the
9941 code away from its former Hollerith-constant appearance, and it's
9942 one less 'int' to worry about when looking at integer-overflow issues.
9943 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9945 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9946 This didn't break anything, but it didn't help either.
9947 It's confusing to put a bogus integer in a place where the actual
9948 value does not matter.
9949 (LIST_END_P): Remove unused macro and its bogus comment.
9950 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9952 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9953 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9955 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9956 We prefer signed types, and the value cannot exceed the EMACS_INT
9957 range anyway (because otherwise the length would not be representable).
9958 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9959 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9960 This avoids a GCC warning when WIDE_EMACS_INT.
9962 * indent.c (sane_tab_width): New function.
9963 (current_column, scan_for_column, Findent_to, position_indentation)
9964 (compute_motion): Use it. This is just for clarity.
9965 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9967 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9969 * lisp.h (lint_assume): New macro.
9970 * composite.c (composition_gstring_put_cache):
9971 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9973 * editfns.c, insdel.c:
9974 Omit unnecessary forward decls, to simplify future changes.
9976 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9978 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9980 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9981 Use much-faster test for byte-length change.
9982 Don't assume string byte-length fits in 'int'.
9983 Check that character arg fits in 'int'.
9984 (mapcar1): Declare byte as byte, for clarity.
9986 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9988 * fns.c (concat): Catch string overflow earlier.
9989 Do not rely on integer wraparound.
9991 * dispextern.h (struct it.overlay_strings_charpos)
9992 (struct it.selective): Now EMACS_INT, not int.
9993 * xdisp.c (forward_to_next_line_start)
9994 (back_to_previous_visible_line_start)
9995 (reseat_at_next_visible_line_start, next_element_from_buffer):
9996 Don't arbitrarily truncate the value of 'selective' to int.
9998 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10000 * composite.c: Don't truncate sizes to 'int'.
10001 (composition_gstring_p, composition_reseat_it)
10002 (composition_adjust_point): Use EMACS_INT, not int.
10003 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10004 not EMACS_UINT, for indexes.
10006 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10008 * buffer.c: Include <verify.h>.
10009 (struct sortvec.priority, struct sortstr.priority):
10010 Now EMACS_INT, not int.
10011 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10012 (struct sortstr.size, record_overlay_string)
10013 (struct sortstrlist.size, struct sortlist.used):
10014 Don't truncate size to int.
10015 (record_overlay_string): Check for size-calculation overflow.
10016 (init_buffer_once): Check at compile-time, not run-time.
10018 2011-06-22 Jim Meyering <meyering@redhat.com>
10020 Don't leak an XBM-image-sized buffer
10021 * image.c (xbm_load): Free the image buffer after using it.
10023 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10026 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10027 that Sun C diagnosed.
10028 * fns.c (secure_hash): Fix pointer signedness issue.
10029 * intervals.c (static_offset_intervals): New function.
10030 (offset_intervals): Use it.
10032 2011-06-21 Leo Liu <sdl.web@gmail.com>
10035 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10038 * fns.c (secure_hash): Rename from crypto_hash_function and change
10039 the first arg to accept symbols.
10040 (Fsecure_hash): New primitive.
10041 (syms_of_fns): New symbols.
10043 2011-06-20 Deniz Dogan <deniz@dogan.se>
10045 * process.c (Fset_process_buffer): Clarify return value in
10048 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10050 * dispnew.c (add_window_display_history): Use BVAR.

10053 (check_window_end, dump_glyph_matrix, dump_glyph)
10054 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10056 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10059 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10060 check till after the cache is created in init_frame_faces.
10062 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10064 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10066 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10068 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10069 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10070 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10072 Improve buffer-overflow checking (Bug#8873).
10073 * fileio.c (Finsert_file_contents):
10074 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10075 Remove the old (too-loose) buffer overflow checks.
10076 They weren't needed, since make_gap checks for buffer overflow.
10077 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10078 The old code merely checked for Emacs fixnum overflow, and relied
10079 on undefined (wraparound) behavior. The new code avoids undefined
10080 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10082 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10083 Tune. Don't use wider integers than needed. Don't use alloca.
10084 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10086 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10088 * insdel.c, lisp.h (buffer_overflow): New function.
10089 (insert_from_buffer_1, replace_range, replace_range_2):
10090 * insdel.c (make_gap_larger):
10091 * editfns.c (Finsert_char):
10092 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10094 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10096 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10098 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10100 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10101 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10103 * fileio.c: Don't assume EMACS_INT fits in off_t.
10104 (emacs_lseek): New static function.
10105 (Finsert_file_contents, Fwrite_region): Use it.
10106 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10108 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10110 * fns.c: Don't overflow int when computing a list length.
10111 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10112 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10113 truncation on 64-bit hosts. Check for QUIT every
10114 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10115 faster and is responsive enough.
10116 (Flength): Report an error instead of overflowing an integer.
10117 (Fsafe_length): Return a float if the value is not representable
10118 as a fixnum. This shouldn't happen except in contrived situations.
10119 (Fnthcdr, Fsort): Don't assume list length fits in int.
10120 (Fcopy_sequence): Don't assume vector length fits in int.
10122 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10123 (header_size, word_size): New constants.
10124 (allocate_vectorlike): Don't check size overflow here.
10125 (allocate_vector): Check it here instead, since this is the only
10126 caller of allocate_vectorlike that could cause overflow.
10127 Check that the new vector's length is representable as a fixnum.
10129 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10130 The previous code was bogus. For example, next_almost_prime (32)
10131 returned 39, which is undesirable as it is a multiple of 3; and
10132 next_almost_prime (24) returned 25, which is a multiple of 5 so
10133 why was the code bothering to check for multiples of 7?
10135 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10137 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10139 Variadic C functions now count arguments with ptrdiff_t.
10140 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10141 Back then I didn't know that the Emacs coding style prefers signed int.
10142 Also, in the meantime I found a few more instances where arguments
10143 were being counted with int, which may truncate counts on 64-bit
10144 machines, or EMACS_INT, which may be unnecessarily wide.
10145 * lisp.h (struct Lisp_Subr.function.aMANY)
10146 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10147 Arg counts are now ptrdiff_t, not size_t.
10148 All variadic functions and their callers changed accordingly.
10149 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10150 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10151 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10152 * callint.c (Fcall_interactively): Check arg count for overflow,
10153 to avoid potential buffer overrun. Use signed char, not 'int',
10154 for 'varies' array, so that we needn't bother to check its size
10155 calculation for overflow.
10156 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10157 * eval.c (apply_lambda):
10158 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10159 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10160 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10162 * callint.c (Fcall_interactively): Don't use index var as event count.
10164 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10165 * mem-limits.h (SIZE): Remove; no longer used.
10167 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10169 Remove unnecessary casts.
10170 * xterm.c (x_term_init):
10171 * xfns.c (x_set_border_pixel):
10172 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10173 These aren't needed now that we assume ANSI C.
10175 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10176 It's more likely to cause problems (due to unsigned overflow)
10179 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10181 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10183 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10185 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10187 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10189 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10191 GLYPH_CODE_FACE returns EMACS_INT, not int.
10192 * dispextern.h (merge_faces):
10193 * xfaces.c (merge_faces):
10194 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10195 Don't assume EMACS_INT fits in int.
10197 * character.h (CHAR_VALID_P): Remove unused parameter.
10198 * fontset.c, lisp.h, xdisp.c: All uses changed.
10200 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10202 * fns.c (concat): Minor tuning based on overflow analysis.
10203 This doesn't fix any bugs. Use int to hold character, instead
10204 of constantly refetching from Emacs object. Use XFASTINT, not
10205 XINT, for value known to be a character. Don't bother comparing
10206 a single byte to 0400, as it's always less.
10208 * floatfns.c (Fexpt):
10209 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10211 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10214 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10216 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10217 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10218 incorrectly succeed when S was a string, because 4294967386 was
10219 truncated before it was used.
10221 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10222 Otherwise, an out-of-range integer could cause undefined behavior
10225 * composite.c: Use int, not EMACS_INT, for characters.
10226 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10227 EMACS_INT, for values that are known to be in character range.
10228 This doesn't fix any bugs but is the usual style inside Emacs and
10229 may generate better code on 32-bit machines.
10231 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10232 This is for reasons similar to the recent CHAR_STRING fix.
10233 * charset.c (Fencode_char): Check that character arg is actually
10234 a character. Pass an int to ENCODE_CHAR.
10235 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10236 wider than 'int', as a compile-time check to prevent future regressions
10239 * character.c (char_string): Remove unnecessary casts.
10241 Make sure a 64-bit char is never passed to CHAR_STRING.
10242 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10243 by silently ignoring the top 32 bits, allowing some values
10244 that were far too large to be valid characters.
10245 * character.h: Include <verify.h>.
10246 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10247 arguments are no wider than unsigned, as a compile-time check
10248 to prevent future regressions in this area.
10250 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10251 (Fsubst_char_in_region):
10253 * xdisp.c (decode_mode_spec_coding):
10254 Adjust to CHAR_STRING's new requirement.
10255 * editfns.c (Finsert_char, Fsubst_char_in_region):
10256 * fns.c (concat): Check that character args are actually
10257 characters. Without this test, these functions did the wrong
10258 thing with wildly out-of-range values on 64-bit hosts.
10260 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10261 These casts should not be needed on 32-bit hosts, either.
10262 * keyboard.c (read_char):
10263 * lread.c (Fload): Remove casts to unsigned.
10265 * lisp.h (UNSIGNED_CMP): New macro.
10266 This fixes comparison bugs on 64-bit hosts.
10267 (ASCII_CHAR_P): Use it.
10268 * casefiddle.c (casify_object):
10269 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10270 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10271 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10272 * dispextern.h (FACE_FROM_ID):
10273 * keyboard.c (read_char): Use UNSIGNED_CMP.
10275 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10276 not to EMACS_INT, to avoid GCC warning.
10278 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10280 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10281 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10282 isn't needed on 32-bit machines.
10284 * buffer.c (Fgenerate_new_buffer_name):
10285 Use EMACS_INT for count, not int.
10286 (advance_to_char_boundary): Return EMACS_INT, not int.
10288 * data.c (Qcompiled_function): Now static.
10290 * window.c (window_body_lines): Now static.
10292 * image.c (gif_load): Rename local to avoid shadowing.
10294 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10295 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10296 * alloc.c (make_save_value): Integer argument is now of type
10297 ptrdiff_t, not int.
10298 (mark_object): Use ptrdiff_t, not int.
10299 * lisp.h (pD): New macro.
10300 * print.c (print_object): Use it.
10302 * alloc.c: Use EMACS_INT, not int, to count objects.
10303 (total_conses, total_markers, total_symbols, total_vector_size)
10304 (total_free_conses, total_free_markers, total_free_symbols)
10305 (total_free_floats, total_floats, total_free_intervals)
10306 (total_intervals, total_strings, total_free_strings):
10307 Now EMACS_INT, not int. All uses changed.
10308 (Fgarbage_collect): Compute overall total using a double, so that
10309 integer overflow is less likely to be a problem. Check for overflow
10310 when converting back to an integer.
10311 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10312 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10313 These were 'int' variables that could overflow on 64-bit hosts;
10314 they were never used, so remove them instead of repairing them.
10315 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10316 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10317 Previously, this ceilinged at INT_MAX, but that doesn't work on
10319 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10321 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10322 (allocate_vectorlike): Check for ptrdiff_t overflow.
10323 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10324 when a (possibly-narrower) signed value would do just as well.
10325 We prefer using signed arithmetic, to avoid comparison confusion.
10327 * alloc.c: Catch some string size overflows that we were missing.
10328 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10329 for convenience in STRING_BYTES_MAX.
10330 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10331 The definition here is exact; the one in lisp.h was approximate.
10332 (allocate_string_data): Check for string overflow. This catches
10333 some instances we weren't catching before. Also, it catches
10334 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10335 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10336 and ptrdiff_t and EMACS_INT are both 64 bits.
10338 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10339 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10340 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10342 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10344 * alloc.c (Fmake_string): Check for out-of-range init.
10346 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10348 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10350 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10352 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10353 xg_get_default_scrollbar_width.
10355 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10356 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10357 (style_changed_cb): Call update_theme_scrollbar_width and call
10358 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10359 all frames (Bug#8505).
10360 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10361 Call gtk_window_set_resizable if HAVE_GTK3.
10362 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10363 and height if HAVE_GTK3 (Bug#8505).
10364 (scroll_bar_width_for_theme): New variable.
10365 (update_theme_scrollbar_width): New function.
10366 (xg_get_default_scrollbar_width): Move code to
10367 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10368 (xg_initialize): Call update_theme_scrollbar_width.
10370 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10372 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10374 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10376 * frame.c (make_frame): Call other_buffer_safely instead of
10379 * window.c (temp_output_buffer_show): Call display_buffer with
10380 second argument Vtemp_buffer_show_specifiers and reset latter
10381 immediately after the call.
10382 (Vtemp_buffer_show_specifiers): New variable.
10383 (auto_window_vscroll_p, next_screen_context_lines)
10384 (Vscroll_preserve_screen_position): Remove leading asterisks from
10387 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10389 Fix minor problems found by GCC 4.6.0 static checking.
10390 * buffer.c (Qclone_number): Remove for now, as it's unused.
10391 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10392 (record_buffer): Remove unused local.
10393 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10394 (set_frame_buffer_list): Remove; unused.
10395 * frame.h (other_visible_frames): Remove decl.
10396 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10397 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10398 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10400 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10401 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10402 Define only if HAVE_GPM.
10403 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10404 (update_hints_inhibit): Remove; never set. All uses removed.
10405 * widgetprv.h (emacsFrameClassRec): Remove decl.
10406 * window.c (delete_deletable_window): Now returns void, since it
10407 wasn't returning anything.
10408 (compare_window_configurations): Remove unused locals.
10409 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10410 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10411 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10412 the same widths as pointers. This follows up on the 2011-05-06 patch.
10413 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10414 * xterm.h: Likewise.
10415 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10417 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10419 * makefile.w32-in: Update dependencies.
10420 (LISP_H): Add lib/intprops.h.
10422 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10424 * image.c (gif_load): Add animation frame delay to the metadata.
10425 (syms_of_image): Use DEFSYM. New symbol `delay'.
10427 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10429 * window.c (delete_deletable_window): Re-add.
10430 (Fset_window_configuration): Rewrite to handle dead buffers and
10431 consequently deletable windows.
10432 (window_tree, Fwindow_tree): Remove. Supply functionality in
10434 (compare_window_configurations): Simplify code.
10436 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10438 * image.c (imagemagick_load_image): Fix type mismatch.
10439 (Fimagemagick_types): Likewise.
10441 * window.h (replace_buffer_in_windows): Declare.
10443 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10445 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10446 Qclone_number. Remove external declaration of Qdelete_window.
10447 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10449 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10450 Run Qbuffer_list_update_hook if allowed.
10451 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10452 buffer list implementation.
10453 (other_buffer_safely): New function.
10454 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10455 calls to replace_buffer_in_windows and
10456 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10458 (record_buffer): Inhibit quitting and rewrite using quittable
10459 functions. Run Qbuffer_list_update_hook if allowed.
10460 (Frecord_buffer, Funrecord_buffer): New functions.
10461 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10462 Move switch-to-buffer to window.el.
10463 (bury-buffer): Move to window.el.
10464 (Vbuffer_list_update_hook): New variable.
10466 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10469 * window.h (resize_frame_windows): Move up in code.
10470 (Fwindow_frame): Remove EXFUN.
10471 (replace_buffer_in_all_windows): Remove prototype.
10472 (replace_buffer_in_windows_safely): Add prototype.
10474 * window.c: Declare Qdelete_window static again. Move down
10475 declaration of select_count.
10476 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10477 (Fother_window): Move to window.el.
10478 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10479 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10480 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10482 (replace_buffer_in_windows): Implement by calling
10483 Qreplace_buffer_in_windows.
10484 (replace_buffer_in_all_windows): Remove with some functionality

10932 according to the row's direction when priming the loop that looks
10933 for the glyph on which to display cursor.
10934 (single_display_spec_intangible_p): Function deleted.
10935 (display_prop_intangible_p): Reimplement to call
10936 handle_display_spec instead of single_display_spec_intangible_p.
10937 Accept 3 additional arguments needed by handle_display_spec.
10938 This fixes incorrect cursor motion across display property with complex
10939 values: lists, `(when COND...)' forms, etc.
10940 (single_display_spec_string_p): Support property values that are
10941 lists with the argument STRING its top-level element.
10942 (display_prop_string_p): Fix the condition for processing a
10943 property that is a list to be consistent with handle_display_spec.
10944 (handle_display_spec): New function, refactored from the
10945 last portion of handle_display_prop.
10946 (compute_display_string_pos): Accept additional argument
10947 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10948 value of a `display' property is a "replacing spec".
10949 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10950 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10951 the display property, but just return a value indicating whether
10952 the display property will replace the characters it covers.
10953 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10954 frame_window_p members of struct bidi_it.
10955 (compute_display_string_pos, compute_display_string_end):
10957 (push_it): Accept second argument POSITION, where pop_it should
10958 jump to continue iteration.
10959 (reseat_1): Initialize bidi_it.disp_pos.
10961 * keyboard.c (adjust_point_for_property): Adjust the call to
10962 display_prop_intangible_p to its new signature.
10964 * dispextern.h (struct bidi_it): New member frame_window_p.
10965 (bidi_init_it): Update prototypes.
10966 (display_prop_intangible_p): Update prototype.
10967 (compute_display_string_pos, compute_display_string_end):
10968 Declare prototypes.
10969 (struct bidi_it): New members nchars and disp_pos. ch_len is now
10972 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
10974 Malloc failure behavior now depends on size of allocation.
10975 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
10976 * lisp.h: Change signatures accordingly.
10977 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
10978 All callers changed. (Bug#8762)
10980 * gnutls.c: Use Emacs's memory allocators.
10981 Without this change, the gnutls library would invoke malloc etc.
10982 directly, which causes problems on non-SYNC_INPUT hosts, and which
10983 runs afoul of improving memory_full behavior. (Bug#8761)
10984 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10985 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10986 xfree instead of the default malloc, realloc, free.
10987 (Fgnutls_boot): No need to check for memory allocation failure,
10988 since xmalloc does that for us.
10990 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
10991 * category.c (hash_get_category_set):
10992 * ccl.c (ccl_driver):

11004 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11005 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11006 * image.c (make_image, search_image_cache, lookup_image)
11007 (xpm_put_color_table_h):
11008 * lisp.h (struct Lisp_Hash_Table):
11009 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11010 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11011 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11012 * alloc.c (allocate_vectorlike):
11013 Check for overflow in vector size calculations.
11014 * ccl.c (ccl_driver):
11015 Check for overflow when converting EMACS_INT to int.
11016 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11017 need to be updated by these changes.
11018 * fns.c (make_hash_table, maybe_resize_hash_table):
11019 Check for integer overflow with large hash tables.
11020 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11021 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11022 (SXHASH_REDUCE): New macro.
11023 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11024 Use it instead of discarding useful hash info with large hash values.
11025 (sxhash_float): New function.
11026 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11027 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11028 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11029 Rewrite to use FIXNUM_BITS, as this simplifies things.
11030 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11031 Adjust signatures to match updated version of code.
11032 (consing_since_gc): Now EMACS_INT, since a single hash table can
11033 use more than INT_MAX bytes.
11035 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11037 Make it possible to build with GCC-4.6+ -O2 -flto.
11039 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11041 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11043 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11044 Call minibuffer-inactive-mode.
11046 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11048 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11049 Update dependencies.
11051 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11053 * data.c (init_data): Remove code for UTS, this system is not
11056 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11058 Don't force ./temacs to start in terminal mode.
11060 * frame.c (make_initial_frame): Initialize faces in all cases, not
11061 only when CANNOT_DUMP is defined.
11062 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11064 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11066 * dispnew.c (add_window_display_history): Use const for the string
11067 pointer. Remove declaration, not needed.
11069 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11071 Use 'inline', not 'INLINE'.
11072 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11073 * alloc.c, fontset.c (INLINE): Remove.
11074 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11075 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11076 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11077 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11078 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11080 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11082 Make it possible to run ./temacs.
11084 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11085 syms_of_callproc does the same thing. Remove test for
11086 "initialized", do it in the caller.
11087 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11089 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11091 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11092 (read_minibuf): Use get_minibuffer.
11093 (syms_of_minibuf): Use DEFSYM.
11094 (Qmetadata): New var.
11095 * data.c (Qbuffer): Don't make it static.
11096 (syms_of_data): Use DEFSYM.
11098 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11100 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11101 (CCL_CODE_MIN): New macro.
11103 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11105 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11107 * eval.c (Qdebug): Now static.
11108 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11109 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11110 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11112 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11114 * image.c: Various fixes to ImageMagick code comments.
11115 (Fimagemagick_types): Doc fix.
11117 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11119 Minor fixes prompted by GCC 4.6.0 warnings.
11121 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11123 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11124 (x_clipboard_manager_save_all): Move extern decl to ...
11125 * xterm.h: ... here, so that it can be checked for consistency.
11127 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11129 * xselect.c (x_clipboard_manager_save_frame)
11130 (x_clipboard_manager_save_all): New functions.
11131 (Fx_clipboard_manager_save): Lisp function deleted.
11133 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11134 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11136 * xterm.h: Update prototype.
11138 2011-05-28 William Xu <william.xwl@gmail.com>
11140 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11141 exiting (Bug#8239).
11143 2011-05-28 Jim Meyering <meyering@redhat.com>
11145 Avoid a sign-extension bug in crypto_hash_function.
11146 * fns.c (to_uchar): Define.
11147 (crypto_hash_function): Use it to convert some newly-signed
11148 variables to unsigned, to avoid sign-extension bugs. For example,
11149 without this change, (md5 "truc") would evaluate to
11150 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11151 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11152 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11154 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11156 Integer overflow fixes.
11158 * dbusbind.c: Serial number integer overflow fixes.
11159 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11160 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11161 to hold a serial number that is too large for a fixnum.
11162 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11163 Check for serial numbers out of range. Decode any serial number
11164 that was so large that it became a float. (Bug#8722)
11166 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11167 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11168 Use XFASTINT rather than XUINT when numbers are nonnegative.
11169 (xd_append_arg, Fdbus_method_return_internal):
11170 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11171 arguments, check that Lisp number is nonnegative, rather than
11172 silently wrapping negative numbers around. (Bug#8722)
11173 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11176 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11178 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11180 ccl: Add integer overflow checks.
11181 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11182 (IN_INT_RANGE): New macros.
11183 (ccl_driver): Use them to check for integer overflow when
11184 decoding a CCL program. Many of the new checks are whether XINT (x)
11185 fits in int; it doesn't always, on 64-bit hosts. The new version
11186 doesn't catch all possible integer overflows, but it's an
11187 improvement. (Bug#8719)
11189 * alloc.c (make_event_array): Use XINT, not XUINT.
11190 There's no need for unsigned here.
11192 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11193 This follows up to the 2011-05-06 change that substituted uintptr_t
11194 for EMACS_INT. This case wasn't caught back then.
11196 Rework Fformat to avoid integer overflow issues.
11197 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11198 now (part of C89). Include <verify.h>.
11199 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11200 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11201 (Fformat): Avoid the prepass trying to compute sizes; it was only
11202 approximate and thus did not catch overflow reliably. Instead, walk
11203 through the format just once, formatting and computing sizes as we go,
11204 checking for integer overflow at every step, and allocating a larger
11205 buffer as needed. Keep track separately whether the format is
11206 multibyte. Keep only the most-recently calculated precision, rather
11207 than them all. Record whether each argument has been converted to
11208 string. Use EMACS_INT, not int, for byte and char and arg counts.
11209 Support field widths and precisions larger than INT_MAX. Avoid
11210 sprintf's undefined behavior with conversion specifications such as %#d
11211 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11212 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11213 formatting out-of-range floating point numbers with int
11214 formats. (Bug#8668)
11216 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11218 * data.c: Avoid integer truncation in expressions involving floats.
11219 * data.c: Include <intprops.h>.
11220 (arith_driver): When there's an integer overflow in an expression
11221 involving floating point, convert the integers to floating point
11222 so that the resulting value does not suffer from catastrophic
11223 integer truncation. For example, on a 64-bit host (* 4
11224 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11225 Do not rely on undefined behavior after integer overflow.
11227 merge count_size_as_multibyte, parse_str_to_multibyte
11228 * character.c, character.h (count_size_as_multibyte):
11229 Rename from parse_str_to_multibyte; all uses changed.
11230 Check for integer overflow.
11231 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11232 since it's now a duplicate of the other. This is more of
11233 a character than a buffer op, so better that it's in character.c.
11234 * fns.c, print.c: Adjust to above changes.
11236 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11238 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11240 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11242 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11243 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11244 (x_clipboard_manager_save): Now static.
11245 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11247 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11248 (crypto_hash_function): Now static.
11249 Fix pointer signedness problems. Avoid unnecessary initializations.
11251 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11253 * termhooks.h (Vselection_alist): Make it terminal-local.
11255 * terminal.c (create_terminal): Initialize it.
11257 * xselect.c: Support for clipboard managers.
11258 (Vselection_alist): Move to termhooks.h as terminal-local var.
11259 (LOCAL_SELECTION): New macro.
11260 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11261 (symbol_to_x_atom): Remove gratuitous arg.
11262 (x_handle_selection_request, lisp_data_to_selection_data)
11263 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11264 (x_own_selection, x_get_local_selection, x_convert_selection):
11265 New arg, specifying work frame. Use terminal-local Vselection_alist.
11266 (some_frame_on_display): Delete unused function.
11267 (Fx_own_selection_internal, Fx_get_selection_internal)
11268 (Fx_disown_selection_internal, Fx_selection_owner_p)
11269 (Fx_selection_exists_p): New optional frame arg.
11270 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11271 (x_handle_selection_clear): Don't treat other terminals with the
11272 same keyboard specially. Use the terminal-local Vselection_alist.
11273 (x_clear_frame_selections): Use Frun_hook_with_args.
11275 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11277 * xterm.h: Add support for those atoms.
11279 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11281 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11282 (converted_selections, conversion_fail_tag): New global variables.
11283 (x_selection_request_lisp_error): Free the above.
11284 (x_get_local_selection): Remove unnecessary code.
11285 (x_reply_selection_request): Args changed; handle arbitrary array
11286 of converted selections stored in converted_selections.
11287 Separate the XChangeProperty and SelectionNotify steps.
11288 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11289 (x_convert_selection): New function.
11290 (x_handle_selection_event): Simplify.
11291 (x_get_foreign_selection): Don't ignore incoming requests while
11292 waiting for an answer; this will fail when we implement
11293 SAVE_TARGETS, and seems unnecessary anyway.
11294 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11295 (Vx_sent_selection_functions): Doc fix.
11297 2011-05-26 Leo Liu <sdl.web@gmail.com>
11299 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11301 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11303 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11305 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11306 for fringe update if it has periodic bitmap.
11307 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11308 and fringe_bitmap_periodic_p.
11310 * fringe.c (get_fringe_bitmap_data): New function.
11311 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11312 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11313 row. Mark glyph row for fringe update if periodicity changed.
11315 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11316 for fringe update unless it has periodic bitmap.
11318 2011-05-25 Kenichi Handa <handa@m17n.org>
11320 * xdisp.c (get_next_display_element): Set correct it->face_id for
11321 a static composition.

11335 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11336 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11337 Remove macros that are defined and never used.
11338 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11340 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11342 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11343 (Fx_get_selection_internal): Minor cleanup.

11362 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11363 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11364 and add some more files.
11366 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11368 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11369 report_file_error introduced by the change from 2011-05-07.
11371 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11373 * systime.h (Time): Define only if emacs is defined.
11374 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11375 where the include path doesn't have X11/X.h by default. See
11376 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11378 2011-05-20 Kenichi Handa <handa@m17n.org>
11380 * composite.c (find_automatic_composition): Fix previous change.
11382 2011-05-20 Glenn Morris <rgm@gnu.org>
11384 * lisp.mk: New file, split from Makefile.in.
11385 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11386 (shortlisp): Remove.
11387 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11389 2011-05-19 Glenn Morris <rgm@gnu.org>
11391 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11392 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11393 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11394 (lisp): Set the order to that of loadup.el.
11395 (shortlisp): Make it a copy of $lisp.
11396 (SOME_MACHINE_LISP): Remove.
11397 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11398 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11400 2011-05-18 Kenichi Handa <handa@m17n.org>
11402 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11403 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11404 (find_automatic_composition): Mostly rewrite for efficiency.
11406 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11408 * makefile.w32-in: Update dependencies.
11410 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11412 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11413 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11415 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11417 Fix some integer overflow issues, such as string length overflow.
11419 * insdel.c (count_size_as_multibyte): Check for string overflow.
11421 * character.c (lisp_string_width): Check for string overflow.
11422 Use EMACS_INT, not int, for string indexes and lengths; in
11423 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11424 the resulting string length overflows an EMACS_INT; instead,
11425 report a string overflow if no precision given. When checking for
11426 precision exhaustion, use a check that cannot possibly have
11427 integer overflow. (Bug#8675)
11428 * character.h (lisp_string_width): Adjust to new signature.
11430 * alloc.c (string_overflow): New function.
11431 (Fmake_string): Use it. This doesn't change behavior, but saves
11432 a few bytes and will simplify future changes.
11433 * character.c (string_escape_byte8): Likewise.
11434 * lisp.h (string_overflow): New decl.
11436 Fixups, following up to the user-interface timestamp change.
11437 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11438 for UI timestamps, instead of unsigned long.
11439 * msdos.c (mouse_get_pos): Likewise.
11440 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11441 * w32gui.h (Time): Define by including "systime.h" rather than by
11442 declaring it ourselves. (Bug#8664)
11444 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11445 * image.c (clear_image_cache): Likewise.
11447 * term.c (term_mouse_position): Don't assume time_t wraparound.
11449 Be more systematic about user-interface timestamps.
11450 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11451 and sometimes 'EMACS_UINT', to represent these timestamps.
11452 This change causes it to use 'Time' uniformly, as that's what X uses.
11453 This makes the code easier to follow, and makes it easier to catch
11454 integer overflow bugs such as Bug#8664.
11455 * frame.c (Fmouse_position, Fmouse_pixel_position):
11456 Use Time, not unsigned long, for user-interface timestamps.
11457 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11458 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11459 * keyboard.h (last_event_timestamp): Likewise.
11460 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11461 * menu.h (xmenu_show): Likewise.
11462 * term.c (term_mouse_position): Likewise.
11463 * termhooks.h (struct input_event.timestamp): Likewise.
11464 (struct terminal.mouse_position_hook): Likewise.
11465 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11466 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11467 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11468 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11469 what it was before.
11470 * menu.h, termhooks.h: Include "systime.h", for Time.
11472 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11473 Don't assume that the difference between two unsigned long values
11474 can fit into an integer. At this point, we know button_down_time
11475 <= event->timestamp, so the difference must be nonnegative, so
11476 there's no need to cast the result if double-click-time is
11477 nonnegative, as it should be; check that it's nonnegative, just in
11478 case. This bug is triggered when events are more than 2**31 ms
11479 apart (about 25 days). (Bug#8664)
11481 * xselect.c (last_event_timestamp): Remove duplicate decl.
11482 (x_own_selection): Remove needless cast to unsigned long.
11484 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11485 that always fit in int. Use a sentinel instead of a counter, to
11486 avoid a temp and to allay GCC's concerns about possible int overflow.
11487 * frame.h (struct frame): Use int for menu_bar_items_used
11488 instead of EMACS_INT, since it always fits in int.
11490 * menu.c (grow_menu_items): Check for int overflow.
11492 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11494 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11495 Before, the code was not consistent. These values cannot exceed
11496 2**31 - 1 so there's no need to make them unsigned.
11497 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11498 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11499 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11501 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11503 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11504 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11505 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11506 presumably because the widths might not match.
11508 * window.c (size_window): Avoid needless test at loop start.
11510 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11512 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11514 2011-05-12 Drew Adams <drew.adams@oracle.com>
11516 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11518 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11520 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11521 `width' to `bar_area_x' and `bar_area_width', respectively.
11522 (x_scroll_run): Take account of fringe background extension.
11524 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11525 Rename local vars `left' and `width' to `bar_area_x' and
11526 `bar_area_width', respectively.
11527 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11528 background extension.
11530 2011-05-10 Jim Meyering <meyering@redhat.com>
11532 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11534 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11536 * image.c (Finit_image_library): Return t for built-in image types,
11537 like pbm and xbm. (Bug#8640)
11539 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11541 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11543 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11545 * w32console.c (Fset_screen_color): Doc fix.
11546 (Fget_screen_color): New function.
11547 (syms_of_ntterm): Defsubr it.
11549 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11550 unlink the temporary file if Fcall_process didn't create it in the
11552 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11553 child process will be redirected to a file specified with `:file'.
11554 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11555 cue to call_process_cleanup not to close that handle.
11557 2011-05-07 Ben Key <bkey76@gmail.com>
11559 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11560 one of two shell specific rules, either bootstrap-temacs-CMD or
11561 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11562 to the previous implementation of the bootstrap-temacs rule.
11563 The bootstrap-temacs-CMD rule is similar to the previous
11564 implementation of the bootstrap-temacs rule except that it
11565 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11568 These changes, along with some changes to nt/configure.bat,
11569 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11570 earlier fix to add support for --cflags and --ldflags options
11571 that include quotes so that it works whether make uses cmd or
11574 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11576 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11577 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11579 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11580 a string. Handle both cases.
11581 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11582 (Fdbus_register_method): Use Qinvalid_function.
11584 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11586 * makefile.w32-in: Update dependencies.
11587 (LISP_H): Add inttypes.h and stdin.h.
11588 (PROCESS_H): Add unistd.h.
11590 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11592 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11593 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11595 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11597 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11599 * term.c (vfatal): Remove stray call to va_end.
11600 It's not needed and the C Standard doesn't allow it here anyway.
11602 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11603 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11605 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11608 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11610 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11612 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11614 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11616 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11618 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11619 * charset.c (Fdefine_charset_internal): Don't initialize
11620 charset.code_space[15]. The value was garbage, on hosts with
11621 32-bit int (Bug#8600).
11623 * lread.c (read_integer): Be more consistent with string-to-number.
11624 Use string_to_number to do the actual conversion; this avoids
11625 rounding errors and fixes some other screwups. Without this fix,
11626 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11627 (digit_to_number): Move earlier, for benefit of read_integer.
11628 Return -1 if the digit is out of range for the base, -2 if it is
11629 not a digit in any supported base. (Bug#8602)
11631 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11633 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11634 to match comment at start of function. This also removes a
11635 GCC warning about overflow in a 32+64-bit port.
11637 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11639 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11640 Reported by Stefan Monnier in
11641 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11642 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11643 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11645 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11646 (EMACS_UINTPTR): Likewise, with uintptr_t.
11648 * lisp.h: Prefer 64-bit EMACS_INT if available.
11649 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11650 on 32-bit hosts that have 64-bit int, so that they can access
11652 However, temporarily disable this change unless the temporary
11653 symbol WIDE_EMACS_INT is defined.
11655 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11657 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11658 This removes an assumption that EMACS_INT and long are the same
11659 width as pointers. The assumption is true for Emacs porting targets
11660 now, but we want to make other targets possible.
11661 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11662 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11663 In the rest of the code, change types of integers that hold casted
11664 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11665 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11666 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11667 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11668 No need to cast type when ORing.
11669 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11670 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11671 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11672 assume EMACS_INT is the same width as char *.
11673 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11674 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11675 Remove no-longer-needed casts.
11676 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11677 (xg_tool_bar_help_callback, xg_make_tool_item):
11678 Use EMACS_INTPTR to hold an integer
11679 that will be cast to void *; this can avoid a GCC warning
11680 if EMACS_INT is not the same width as void *.
11681 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11682 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11683 (current_message_1, set_message_1):
11684 Use a local to convert to proper width without a cast.
11685 * xmenu.c (dialog_selection_callback): Likewise.
11687 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11688 Also, don't assume VALBITS / RAND_BITS is less than 5,
11689 and don't rely on undefined behavior when shifting a 1 left into
11691 * lisp.h (get_random): Change signature to match.
11693 * lread.c (hash_string): Use size_t, not int, for hash computation.
11694 Normally we prefer signed values; but hashing is special, because
11695 it's better to use unsigned division on hash table sizes so that
11696 the remainder is nonnegative. Also, size_t is the natural width
11697 for hashing into memory. The previous code used 'int', which doesn't
11698 retain enough info to hash well into very large tables.
11699 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11701 * dbusbind.c: Don't possibly lose pointer info when converting.
11702 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11703 Use XPNTR rather than XHASH, so that the high-order bits of
11704 the pointer aren't lost when converting through void *.
11706 * eval.c (Fautoload): Don't double-shift a pointer.
11708 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11710 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11712 * gnutls.c (DEF_GNUTLS_FN):
11713 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11715 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11717 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11720 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11722 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11723 New version that can reserve upto 2GB of heap space.
11725 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11727 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11729 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11731 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11732 `gnutls_certificate_set_x509_key_file'.
11734 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11736 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11737 Update dependencies.
11739 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11741 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11742 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11743 Remove unused parameter `fildes'.
11744 * process.c (read_process_output, send_process): Don't pass it.
11746 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11748 Fix previous change: the library cache is defined in w32.c.
11749 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11750 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11752 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11754 Implement dynamic loading of GnuTLS on Windows.
11756 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11757 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11758 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11761 * gnutls.c (Qgnutls_dll): Define.
11762 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11763 (gnutls_*): Declare function pointers.
11764 (init_gnutls_functions): New function to initialize function pointers.
11765 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11766 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11767 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11768 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11769 (emacs_gnutls_write, emacs_gnutls_read)
11770 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11771 (Fgnutls_available_p): New function.
11772 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11773 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11774 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11776 * image.c: Include w32.h.
11777 (Vimage_type_cache): Delete.
11778 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11779 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11780 (w32_delayed_load): Move to w32.c.

11791 * process.c: Include lisp.h before w32.h, not after.
11792 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11793 instead of gnutls_record_check_pending.

11845 rather than `XVECTOR (FOO)->size'.
11847 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11848 inttypes.h, as a gnulib replacement is used if it not available in

11876 produced by %s or %c overflows available buffer space. (Bug#8545)
11878 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11880 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11883 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11885 * w32.c (init_environment): Warn about defaulting HOME to C:\.

11889 * keyboard.c (Qdelayed_warnings_hook): Define.
11890 (command_loop_1): Run `delayed-warnings-hook'
11891 if Vdelayed_warnings_list is non-nil.
11892 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11893 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11895 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11897 * doprnt.c (doprnt): Don't return value smaller than the buffer
11898 size if the message was truncated. (Bug#8545).
11900 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11902 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

11909 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11911 * makefile.w32-in: Update dependencies.
11913 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11915 Improve `doprnt' and its usage. (Bug#8545)
11916 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11917 `format_end'. Remove support for %l as a conversion specifier.
11918 Don't use xrealloc. Improve diagnostics when the %l size modifier
11919 is used. Update the commentary.
11921 * eval.c (verror): Simplify calculation of size_t.
11923 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11926 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11928 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11931 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11933 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11934 This makes this file independent of the recent pseudovector change.
11936 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11938 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11940 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11941 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11942 Remove unused local.
11943 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11945 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11946 GCC 4.6.0 optimizes based on type-based alias analysis.
11947 For example, if b is of type struct buffer * and v of type struct
11948 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11949 != &v->size, and therefore "v->size = 1; b->size = 2; return
11950 v->size;" must therefore return 1. This assumption is incorrect
11951 for Emacs, since it type-puns struct Lisp_Vector * with many other
11952 types. To fix this problem, this patch adds a new type struct
11953 vectorlike_header that documents the constraints on layout of vectors
11954 and pseudovectors, and helps optimizing compilers not get fooled
11955 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11956 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11957 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11959 (XSETPVECTYPE): Rewrite in terms of new macro.
11960 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11961 This is a bit clearer, and further avoids the possibility of
11962 undesirable aliasing.
11963 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11964 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11965 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11966 since Lisp_Subr is a special case (no "next" field).
11967 (ASIZE): Now uses header.size rather than size.
11968 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11969 to avoid the hassle of writing XVECTOR (foo)->header.size.
11970 (struct vectorlike_header): New type.
11971 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11972 object, to help avoid aliasing.
11973 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11974 (SUBRP): Likewise, since Lisp_Subr is a special case.
11975 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11976 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11977 (struct Lisp_Hash_Table): Combine first two members into a single
11978 struct vectorlike_header member. All uses of "size" and "next" members
11979 changed to be "header.size" and "header.next".
11980 * buffer.h (struct buffer): Likewise.
11981 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11982 * frame.h (struct frame): Likewise.
11983 * process.h (struct Lisp_Process): Likewise.
11984 * termhooks.h (struct terminal): Likewise.
11985 * window.c (struct save_window_data, struct saved_window): Likewise.
11986 * window.h (struct window): Likewise.
11987 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11988 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11989 * buffer.c (init_buffer_once): Likewise.
11990 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11992 * process.c (Fformat_network_address): Use local var for size,
11995 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11997 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11998 * data.c (atof): Remove decl; no longer used or needed.
11999 (digit_to_number): Move to lread.c.
12000 (Fstring_to_number): Use new string_to_number function, to be
12001 consistent with how the Lisp reader treats infinities and NaNs.
12002 Do not assume that floating-point numbers represent EMACS_INT
12003 without losing information; this is not true on most 64-bit hosts.
12004 Avoid double-rounding errors, by insisting on integers when
12005 parsing non-base-10 numbers, as the documentation specifies.
12006 * lisp.h (string_to_number): New decl, replacing ...
12007 (isfloat_string): Remove.
12008 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12009 (read1): Do not accept +. and -. as integers; this
12010 appears to have been a coding error. Similarly, do not accept
12011 strings like +-1e0 as floating point numbers. Do not report
12012 overflow for integer overflows unless the base is not 10 which
12013 means we have no simple and reliable way to continue.
12014 Break out the floating-point parsing into a new
12015 function string_to_number, so that Fstring_to_number parses
12016 floating point numbers consistently with the Lisp reader.
12017 (digit_to_number): Move here from data.c. Make it static inline.
12018 (E_CHAR, EXP_INT): Remove, replacing with ...
12019 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12020 (string_to_number): New function, replacing isfloat_string.
12021 This function checks for valid syntax and produces the resulting
12022 Lisp float number too. Rework it so that string-to-number
12023 no longer mishandles examples like "1.0e+". Use strtoumax,
12024 so that overflow for non-base-10 numbers is reported only when
12025 there's no portable and simple way to convert to floating point.
12027 * textprop.c (set_text_properties_1): Rewrite for clarity,
12028 and to avoid GCC warning about integer overflow.
12030 * intervals.h (struct interval): Use EMACS_INT for members
12031 where EMACS_UINT might cause problems. See
12032 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12033 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12034 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12036 (offset_intervals): Tell GCC not to worry about length overflow
12037 when negating a negative length.
12039 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12040 (overrun_check_free): Likewise.
12042 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12043 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12046 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12047 (gnutls_make_error): Rename local to avoid shadowing.
12048 (gnutls_emacs_global_deinit): ifdef out; not used.
12049 (Fgnutls_boot): Use const for pointer to readonly storage.
12050 Comment out unused local. Fix pointer signedness problems.
12052 * lread.c (openp): Don't stuff size_t into an 'int'.
12053 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12054 about possible signed overflow.
12056 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12057 (GDK_KEY_g): Don't define if already defined.
12058 (xg_prepare_tooltip): Avoid pointer signedness problem.
12059 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12061 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12062 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12064 * xfns.c (Fx_window_property): Simplify a bit,
12065 to make a bit faster and to avoid GCC 4.6.0 warning.
12066 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12068 * fns.c (internal_equal): Don't assume size_t fits in int.
12070 * alloc.c (compact_small_strings): Tighten assertion a little.
12072 Replace pEd with more-general pI, and fix some printf arg casts.
12073 * lisp.h (pI): New macro, generalizing old pEd macro to other
12074 conversion specifiers. For example, use "...%"pI"d..." rather
12075 than "...%"pEd"...".
12076 (pEd): Remove. All uses replaced with similar uses of pI.
12077 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12078 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12079 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12080 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12081 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12082 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12083 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12085 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12086 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12087 * print.c (safe_debug_print, print_object): Likewise.
12088 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12090 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12091 avoiding the 0 flag, which is not portable.
12092 * process.c (Fmake_network_process): Use pI to avoid cast.
12093 * region-cache.c (pp_cache): Likewise.
12094 * xdisp.c (decode_mode_spec): Likewise.
12095 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12096 behavior on 64-bit hosts with printf arg.
12097 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12098 (x_stop_queuing_selection_requests): Likewise.
12099 (x_get_window_property): Don't truncate byte count to an 'int'
12102 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12103 here, since it parses constructs like leading '-' and spaces,
12104 which are not wanted; and it overflows with large numbers.
12105 Instead, simply match F[0-9]+, which is what is wanted anyway.
12107 * alloc.c: Remove unportable assumptions about struct layout.
12108 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12109 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12110 (allocate_vectorlike, make_pure_vector): Use the new macros,
12111 plus offsetof, to remove unportable assumptions about struct layout.
12112 These assumptions hold on all porting targets that I know of, but
12113 they are not guaranteed, they're easy to remove, and removing them
12114 makes further changes easier.
12116 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12117 This doesn't fix a bug but makes the code clearer.
12118 (string_overrun_cookie): Now const. Use initializers that
12119 don't formally overflow signed char, to avoid warnings.
12120 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12121 can cause Emacs to crash when string overrun checking is enabled.
12122 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12123 multiple of sizeof (EMACS_INT); it need not be, if
12124 alignof(EMACS_INT) < sizeof (EMACS_INT).
12125 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12127 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12140 * eval.c (Qdebug): Restore global linkage.
12141 * keyboard.c (debug-on-event): New variable.
12142 (handle_user_signal): Break into debugger when debug-on-event
12143 matches the current signal symbol.
12145 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12147 * alloc.c (check_sblock, check_string_bytes)
12148 (check_string_free_list): Convert to standard C.
12150 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12152 * w32.c (emacs_gnutls_push): Fix typo.
12154 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12156 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12157 "cast to pointer from integer of different size".
12159 Improve doprnt and its use in verror. (Bug#8545)
12160 * doprnt.c (doprnt): Document the set of format control sequences
12161 supported by the function. Use SAFE_ALLOCA instead of always
12164 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12165 is one byte too soon. Don't use xrealloc; instead xfree and
12168 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12170 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12173 * gnutls.c: Renamed global_initialized to
12174 gnutls_global_initialized. Added internals for the
12175 :verify-hostname-error, :verify-error, and :verify-flags
12176 parameters of `gnutls-boot' and documented those parameters in the
12177 docstring. Start callback support.
12178 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12179 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12180 on error. Return error code.
12181 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12182 (emacs_gnutls_read): Likewise.
12183 (Fgnutls_boot): Return handshake error code.
12184 (emacs_gnutls_handle_error): New function.
12185 (wsaerror_to_errno): Likewise.

12190 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12191 (emacs_gnutls_push): Likewise.
12193 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12195 * process.c (wait_reading_process_output): Check if GnuTLS
12196 buffered some data internally if no FDs are set for TLS
12199 * makefile.w32-in (OBJ2): Add gnutls.$(O).
12200 (LIBS): Link to USER_LIBS.

12206 display_replaced_before_p argument into display_replaced_p, to
12207 make it consistent with the commentary. Fix typos in the

12508 * process.c (send_process): Adjust to the new signatures of
12509 emacs_write and emacs_gnutls_write. Do not attempt to store

12703 * font.h (font_close_object): Remove.
12704 * fontset.c (FONTSET_OBJLIST): Remove.

12707 * fontset.h (face_suitable_for_char_p): Remove decl.
12708 * xfaces.c (face_at_string_position):
12709 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
12710 since 0 is always ASCII.
12712 * fns.c (weak_hash_tables): Now static.
12714 * fileio.c: Make symbols static if they're not exported.

12733 * editfns.c, lisp.h (get_operating_system_release): Remove.
12734 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
12735 worth the hassle of breaking this out.
12737 * xterm.c: Make symbols static if they're not exported.
12738 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

12841 * buffer.c (buffer_count): Remove unused var.

12850 * atimer.h (run_all_atimers): Remove; not exported.
12852 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12853 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12854 was inaccessible from Lisp.
12855 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12856 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12858 alloc.c: Import and export fewer symbols, and remove unused items.
12859 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12861 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12862 it's not optimized away by whole-program optimization.

12864 (catchlist, handlerlist, mark_backtrace):
12865 Declare only if BYTE_MARK_STACK.

12874 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12875 (mark_backtrace): Define only if BYTE_MARK_STACK.
12876 * xdisp.c (message_enable_multibyte): Now static.
12878 Declare Lisp_Object Q* variables to be 'static' if not exported.
12879 This makes it easier for human readers (and static analyzers)
12880 to see whether these variables are used from other modules.
12881 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12882 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

12891 Remove decls of unexported vars.
12892 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12894 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12896 Make Emacs functions such as Fatom 'static' by default.
12897 This makes it easier for human readers (and static analyzers)
12898 to see whether these functions can be called from other modules.
12899 DEFUN now defines a static function. To make the function external
12900 so that it can be used in other C modules, use the new macro DEFUE.
12901 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12902 (Finit_image_library):
12903 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12904 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12905 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12906 Remove decls, since these functions are now static.
12907 (Funintern, Fget_internal_run_time): New decls, since these functions
12908 were already external.
12910 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12911 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12917 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12918 Mark functions with DEFUE instead of DEFUN,
12919 if they are used in other modules.
12920 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12921 decls for now-static functions.
12922 * buffer.h (Fdelete_overlay): Remove decl.
12923 * callproc.c (Fgetenv_internal): Mark as internal.

12931 * fileio.c (Fmake_symbolic_link): New forward static decl.
12932 * image.c (Finit_image_library): New forward static decl.
12933 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12934 * intervals.h (Fprevious_property_change):
12935 (Fremove_list_of_text_properties): Remove decls.
12936 * keyboard.c (Fthis_command_keys): Remove decl.
12937 (Fcommand_execute): New forward static decl.

12953 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12955 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12958 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12960 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12961 when at ZV. (Bug#8487)
12963 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12965 * charset.c (Fclear_charset_maps): Use xfree instead of free.

12968 * sound.c (sound_cleanup, alsa_close): Likewise.
12969 * termcap.c (tgetent): Likewise.
12970 * xfns.c (x_default_font_parameter): Likewise.
12971 * xsettings.c (read_and_apply_settings): Likewise.
12973 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12974 (overrun_check_free): Protoize.
12976 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12978 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12979 since callers should never pass a negative size.
12980 Change the signature to match that of plain 'read' and 'write'; see
12981 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12982 * lisp.h: Update prototypes of emacs_write and emacs_read.
12984 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12986 * xdisp.c (redisplay_window): Don't try to determine the character
12987 position of the scroll margin if the window start point w->startp
12988 is outside the buffer's accessible region. (Bug#8468)
12990 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12992 Fix write-region and its subroutines for buffers > 2GB.
12993 * fileio.c (a_write, e_write): Modify declaration of arguments and
12994 local variables to support buffers larger than 2GB.
12995 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12997 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12998 argument, local variables, and return value.
13000 * lisp.h: Update prototypes of emacs_write and emacs_read.
13002 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13004 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13006 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13008 Fix more problems found by GCC 4.6.0's static checks.
13010 * xdisp.c (vmessage): Use a better test for character truncation.
13012 * charset.c (load_charset_map): <, not <=, for optimization,
13013 and to avoid potential problems with integer overflow.
13014 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13015 * casetab.c (set_identity, shuffle): Likewise.
13016 * editfns.c (Fformat): Likewise.
13017 * syntax.c (skip_chars): Likewise.
13019 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13020 This also lets GCC 4.6.0 generate slightly better loop code.
13022 * callint.c (Fcall_interactively): <, not <=, for optimization.
13023 (Fcall_interactively): Count the number of arguments produced,
13024 not the number of arguments given. This is simpler and lets GCC
13025 4.6.0 generate slightly better code.
13027 * ftfont.c: Distingish more carefully between FcChar8 and char.
13028 The previous code passed unsigned char * to a functions like
13029 strlen and xstrcasecmp that expect char *, which does not
13030 conform to the C standard.
13031 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13032 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13033 char * when the C standard requires it.
13035 * keyboard.c (read_char): Remove unused var.
13037 * eval.c: Port to Windows vsnprintf (Bug#8435).
13038 Include <limits.h>.
13039 (SIZE_MAX): Define if the headers do not.
13040 (verror): Do not give up if vsnprintf returns a negative count.
13041 Instead, grow the buffer. This ports to Windows vsnprintf, which
13042 does not conform to C99. Problem reported by Eli Zaretskii.
13043 Also, simplify the allocation scheme, by avoiding the need for
13044 calling realloc, and removing the ALLOCATED variable.
13046 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13048 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13049 But keep the doprint source code for now, as we might revamp it
13050 and use it again (Bug#8435).
13051 * lisp.h (doprnt): Remove.
13052 * Makefile.in (base_obj): Remove doprnt.o.
13053 * deps.mk (doprnt.o): Remove.
13055 error: Print 32- and 64-bit integers portably (Bug#8435).
13056 Without this change, on typical 64-bit hosts error ("...%d...", N)
13057 was used to print both 32- and 64-bit integers N, which relied on
13058 undefined behavior.
13059 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13060 * lisp.h (error, verror): Mark as printf-like functions.
13061 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13062 Report overflow in size calculations when allocating printf buffer.
13063 Do not truncate output string at its first null byte.
13064 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13065 Truncate the output at a character boundary, since vsnprintf does not
13067 * charset.c (check_iso_charset_parameter): Convert internal
13068 character to string before calling 'error', since %c now has the
13070 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13071 overflow when computing char to be passed to 'error'. Do not
13072 pass Lisp_Object to 'error'; pass the integer instead.
13073 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13074 formatted with plain %d.
13076 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13078 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13080 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13082 * xterm.c (x_catch_errors): Remove duplicate declaration.
13084 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13086 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13088 2011-04-10 Jim Meyering <meyering@redhat.com>
13090 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13091 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13092 return ssize_t not "int", and use size_t as the buffer length.
13093 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13094 * gnutls.h: Update declarations.
13095 * process.c (read_process_output): Use ssize_t, to match.
13096 (send_process): Likewise.
13098 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13100 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13102 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13104 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13105 Use unsigned char, to match FcChar8 type definition.
13107 * xterm.c (handle_one_xevent):
13108 * xmenu.c (create_and_show_popup_menu):
13109 * xselect.c (x_decline_selection_request)
13110 (x_reply_selection_request): Avoid type-punned deref of X events.
13112 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13114 Fix some uses of `int' instead of EMACS_INT.
13115 * search.c (string_match_1, fast_string_match)
13116 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13117 (scan_buffer, find_next_newline_no_quit)
13118 (find_before_next_newline, search_command, Freplace_match)

13141 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13142 (encode_invocation_designation): Last argument P_NCHARS is now
13144 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

13168 instead of using internal_with_output_to_temp_buffer.
13169 (Qhelp_form_show): New var.
13170 (syms_of_keyboard): Use DEFSYM macro.
13172 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13206 to system-supplied API.
13208 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13210 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13211 This avoids several warnings with gcc -Wstrict-overflow.
13212 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13213 directly, rather than having caller test rule sign. This avoids
13214 some unnecessary tests.
13215 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13216 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13217 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13219 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13220 (xfont_open): Avoid unnecessary tests.
13222 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13224 * composite.h, composite.c (composition_gstring_put_cache):
13225 Use EMACS_INT, not int, for length.
13227 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13228 breaking out part of COMPOSITION_DECODE_RULE.
13229 (COMPOSITION_DECODE_RULE): Use it.
13230 * composite.c (get_composition_id): Remove unused local vars,
13231 by using the new macro.
13233 * textprop.c (set_text_properties_1): Change while to do-while,
13234 since the condition is always true at first.
13236 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13237 (interval_deletion_adjustment): Return unsigned value.
13240 * process.c (list_processes_1, create_pty, read_process_output):
13241 (exec_sentinel): Remove vars that were set but not used.
13242 (create_pty): Remove unnecessary "volatile"s.
13243 (Fnetwork_interface_info): Avoid possibility of int overflow.

13256 * print.c (print_error_message): Avoid int overflow.
13258 * font.c (font_list_entities): Redo for clarity,
13259 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13261 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13262 (font_score): Avoid potential overflow in diff calculation.
13264 * fns.c (substring_both): Remove var that is set but not used.
13265 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13267 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13269 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13270 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13271 can always succeed if overflow has undefined behavior.
13273 * search.c (boyer_moore, wordify): Remove vars set but not used.
13274 (wordify): Omit three unnecessary tests.
13276 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13277 All callers changed. This avoids the need for an unused var.
13279 * casefiddle.c (casify_region): Remove var that is set but not used.
13281 * dired.c (file_name_completion): Remove var that is set but not used.
13283 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13285 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13286 (Finsert_file_contents): Remove unnecessary code checking fd.
13288 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13289 Check for integer overflow on size calculations.
13291 * buffer.c (Fprevious_overlay_change): Remove var that is set
13294 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13295 Remove vars that are set but not used.
13296 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13297 (timer_check_2): Mark vars as initialized.
13299 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13301 * image.c (lookup_image): Remove var that is set but not used.
13302 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13304 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13305 that are set but not used.
13307 * xfns.c (make_invisible_cursor): Don't return garbage
13308 if XCreateBitmapFromData fails (Bug#8410).
13310 * xselect.c (x_get_local_selection, x_handle_property_notify):
13311 Remove vars that are set but not used.
13313 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13314 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13316 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13317 Remove var that is set but not used.
13318 (scroll_bar_windows_size): Now size_t, not int.
13319 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13320 Check for overflow.
13322 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13323 (map_tty_color) [!defined MSDOS]: Likewise.
13325 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13327 * coding.c: Remove vars that are set but not used.
13328 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13329 All callers changed.
13330 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13331 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13332 (decode_coding_charset): Remove vars that are set but not used.
13334 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13335 that is set but not used.
13337 * print.c (print_object): Remove var that is set but not used.
13339 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13340 The gnulib version avoids calling malloc in the usual case,
13341 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13342 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13343 * filelock.c (current_lock_owner): Likewise.
13344 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13345 * sysdep.c: Include allocator.h, careadlinkat.h.
13346 (emacs_no_realloc_allocator): New static constant.
13347 (emacs_readlink): New function.
13348 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13349 ../lib/careadlinkat.h.
13351 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13353 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13354 first non-nil return value).
13356 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13358 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13359 if not defined (Bug#8403).
13361 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13363 * xdisp.c (display_count_lines): Remove parameter `start',
13364 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13365 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13366 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13368 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13369 and thereabouts. All callers changed.
13370 (get_per_char_metric): Remove parameter `f', unused since
13371 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13373 2011-04-02 Jim Meyering <meyering@redhat.com>
13375 do not dereference NULL upon failed strdup
13376 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13377 (ns_get_family): Likewise.
13379 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13381 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13383 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13385 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13388 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13390 Add lexical binding.
13392 * window.c (Ftemp_output_buffer_show): New fun.
13393 (Fsave_window_excursion):
13394 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13396 * lread.c (lisp_file_lexically_bound_p): New function.
13397 (Fload): Bind Qlexical_binding.
13398 (readevalloop): Remove `evalfun' arg.
13399 Bind Qinternal_interpreter_environment.
13400 (Feval_buffer): Bind Qlexical_binding.
13401 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13403 (syms_of_lread): Declare `lexical-binding'.
13405 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13407 * keyboard.c (eval_dyn): New fun.
13408 (menu_item_eval_property): Use it.
13410 * image.c (parse_image_spec): Use Ffunctionp.
13412 * fns.c (concat, mapcar1): Accept byte-code-functions.
13414 * eval.c (Fsetq): Handle lexical vars.
13415 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13416 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13417 (FletX, Flet): Obey lexical binding.
13418 (Fcommandp): Handle closures.
13419 (Feval): New `lexical' arg.
13420 (eval_sub): New function extracted from Feval. Use it almost
13421 everywhere where Feval was used. Look up vars in lexical env.
13423 (Ffunctionp): Move from subr.el.
13424 (Ffuncall): Handle closures.
13425 (apply_lambda): Remove `eval_flags'.
13426 (funcall_lambda): Handle closures and new byte-code-functions.
13427 (Fspecial_variable_p): New function.
13428 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13429 but without exporting it to Lisp.
13431 * doc.c (Fdocumentation, store_function_docstring):
13432 * data.c (Finteractive_form): Handle closures.
13434 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13437 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13439 (exec_byte_code): New function extracted from Fbyte_code to handle new
13440 calling convention for byte-code-functions. Add new byte-codes.
13442 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13444 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13446 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13448 * xdisp.c (redisplay_internal): Fix prototype.
13450 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13452 * xdisp.c (SCROLL_LIMIT): New macro.
13453 (try_scrolling): Use it when setting scroll_limit.
13454 Limit scrolling to 100 screen lines.
13455 (redisplay_window): Even when falling back on "recentering",
13456 position point in the window according to scroll-conservatively,
13457 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13459 (try_scrolling): When point is above the window, allow searching
13460 as far as scroll_max, or one screenful, to compute vertical
13461 distance from PT to the scroll margin position. This prevents
13462 try_scrolling from unnecessarily failing when
13463 scroll-conservatively is set to a value slightly larger than the
13464 window height. Clean up the case of PT below the margin at bottom
13465 of window: scroll_max can no longer be INT_MAX. When aggressive
13466 scrolling is in use, don't let point enter the opposite scroll
13467 margin as result of the scroll.
13468 (syms_of_xdisp) <scroll-conservatively>: Document the
13469 threshold of 100 lines for never-recentering scrolling.
13471 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13473 * dispextern.h (move_it_by_lines):
13474 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13475 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13476 (message_log_check_duplicate): Remove parameters `prev_bol' and
13477 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13478 (redisplay_internal): Remove parameter `preserve_echo_area',
13479 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13481 * indent.c (Fvertical_motion):
13482 * window.c (window_scroll_pixel_based, Frecenter):
13483 Don't pass `need_y_p' to `move_it_by_lines'.
13485 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13487 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13488 steal a few bits to be more compact.
13489 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13490 Remove unneeded casts.
13492 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13494 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13496 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13497 binding" message (bug#7967).
13499 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13501 Fix more problems found by GCC 4.6.0's static checks.
13503 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13504 Remove unused local var.
13506 * editfns.c (Fmessage_box): Remove unused local var.
13508 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13509 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13510 Omit unused local vars.
13511 * window.c (shrink_windows): Omit unused local var.
13512 * menu.c (digest_single_submenu): Omit unused local var.
13513 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13514 Omit unused local var.
13516 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13517 Don't assume string length fits in int.
13518 (keyremap_step, read_key_sequence): Use size_t for sizes.
13519 (read_key_sequence): Don't check last_real_key_start redundantly.
13521 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13522 instead of alloca (Bug#8344).
13524 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13525 (Fbacktrace_frame): Don't assume nframes fits in int.
13527 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13529 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13532 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13534 * cm.c (calccost): Turn while-do into do-while, for clarity.
13536 * keyboard.c (syms_of_keyboard): Use the same style as later
13537 in this function when indexing through an array. This also
13538 works around GCC bug 48267.
13540 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13542 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13544 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13545 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13547 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13548 This avoids undefined behavior on integer overflow, and is a bit
13549 more convenient anyway since it is compared to a size_t variable.
13551 Variadic C functions now count arguments with size_t, not int.
13552 This avoids an unnecessary limitation on 64-bit machines, which
13553 caused (substring ...) to crash on large vectors (Bug#8344).
13554 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13555 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13775 * buffer.c (Fkill_all_local_variables):
13776 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13778 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13779 unconditionally since it does the check itself.
13781 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13783 Fix more problems found by GCC 4.5.2's static checks.
13785 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13786 the first time through the loop, since we know p0 < p1 then.
13787 This also avoids a gcc -Wstrict-overflow warning.
13789 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13790 leading to a memory leak, possible in functions like
13791 load_charset_map_from_file that can allocate an unbounded number
13792 of objects (Bug#8318).
13794 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13795 that could (at least in theory) be that large.
13797 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13798 This is less likely to overflow, and avoids undefined behavior if
13799 overflow does occur. All callers changed. Use strtoul to scan

13817 * process.c (Fmake_network_process): Use socklen_t, not int,
13818 where POSIX says socklen_t is required in portable programs.
13819 This fixes a porting bug on hosts like 64-bit HP-UX, where
13820 socklen_t is wider than int (Bug#8277).
13821 (Fmake_network_process, server_accept_connection):
13822 (wait_reading_process_output, read_process_output):
13825 * process.c: Rename or move locals to avoid shadowing.

13835 Make tparam.h and terminfo.c consistent.
13836 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13837 Include tparam.h instead, since it declares them.
13838 * cm.h (PC): Remove extern decl; tparam.h now does this.
13839 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13840 * terminfo.c: Include tparam.h, to check interfaces.
13841 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13842 (tparam): Adjust signature to match interface in tparam.h;
13843 this removes some undefined behavior. Check that outstring and len
13844 are zero, which they always are with Emacs.
13845 * tparam.h (PC, BC, UP): New extern decls.
13847 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13848 (xftfont_open): Rename locals to avoid shadowing.

13866 (composition_update_it): Mark var as initialized.
13867 (find_automatic_composition): Mark vars as initialized,
13868 with a FIXME (Bug#8290).

13874 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13875 to avoid shadowing.

13887 Fix pointer signedness.
13888 (alsa_choose_format): Remove unused local var.
13889 (wav_play): Initialize a variable to 0, to prevent undefined
13890 behavior (Bug#8278).
13892 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13894 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13896 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13897 clobbering (Bug#8298).
13898 * sysdep.c (sys_subshell): Likewise.
13899 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13901 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13902 This should get cleaned up, so that child_setup has the
13903 same signature on all platforms.
13905 * callproc.c (call_process_cleanup): Now static.
13906 (relocate_fd): Rename locals to avoid shadowing.
13908 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13910 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13911 not to be necessary, and produces flickering.
13913 2011-03-20 Glenn Morris <rgm@gnu.org>
13915 * config.in: Remove file.
13917 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

13962 Define only if needed.
13964 * unexelf.c (unexec): Name an expression,
13965 to avoid gcc -Wbad-function-cast warning.
13966 Use a different way to cause a compilation error if anyone uses
13967 n rather than nn, a way that does not involve shadowing.
13968 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13970 * deps.mk (unexalpha.o): Remove; unused.

14027 * callint.c (quotify_arg, quotify_args): Now static.
14028 (Fcall_interactively): Rename locals to avoid shadowing.

14036 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14037 some of which prompt warnings from gcc -Wbad-function-cast.
14038 (Fformat_time_string, Fencode_time, Finsert_char):

14067 (Fmemory_limit): Cast sbrk's returned value to char *.
14069 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14070 avoids undefined behavior in theory.
14072 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14074 Use functions, not macros, for up- and down-casing (Bug#8254).
14075 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14076 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14077 to use the following functions instead of these macros.
14078 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14079 EMACS_INT, since callers assume the returned value fits in int.
14080 (upcase1): Likewise, for UPCASE_TABLE.
14081 (uppercasep, lowercasep, upcase): New static inline functions.
14082 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14092 (regex_compile, re_match_2_internal): Mark locals as initialized.
14093 (RETALLOC_IF): Define only if needed.
14094 (WORDCHAR_P): Likewise. This one is never needed, but is used
14095 only in a comment talking about a compiler bug, so put inside
14096 the #if 0 of that comment.
14097 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14098 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14124 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14125 New macros, so that the caller can use some names other than
14126 gcpro1, gcpro2, etc.
14127 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14129 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14130 argument, for consistency with GCPRO2_VAR, etc: it is now the
14131 prefix of the variable, not the variable itself. All uses
14133 * dired.c (directory_files_internal, file_name_completion):
14134 Rename locals to avoid shadowing.
14136 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14137 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14138 dired.c's scmp function, had undefined behavior.
14139 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14140 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14141 * buffer.h: ... to here, because these macros use current_buffer,
14142 and the new implementation with inline functions needs to have
14143 current_buffer in scope now, rather than later when the macros
14145 (downcase, upcase1): New static inline functions.
14146 (DOWNCASE, UPCASE1): Reimplement using these functions.
14147 This avoids undefined behavior in expressions like
14148 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14149 from race conditions in accessing the global variables
14150 case_temp1 and case_temp2.
14151 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14152 * lisp.h (case_temp1, case_temp2): Remove their decls.
14153 * character.h (ASCII_CHAR_P): Move from here ...
14154 * lisp.h: ... to here, so that the inline functions mentioned
14155 above can use them.

14159 * fileio.c (file_name_as_directory, directory_file_name):

14162 (file_name_as_directory): Use const pointers when appropriate.
14163 (Fexpand_file_name): Likewise. In particular, newdir might
14164 point at constant storage, so make it a const pointer.
14165 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14166 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14168 (Fset_file_times, Finsert_file_contents, auto_save_error):

14173 to avoid shadowing.
14175 * marker.c (bytepos_to_charpos): Remove; unused.
14177 * lisp.h (verify_bytepos, count_markers): New decls,
14178 so that gcc does not warn that these functions aren't declared.
14180 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14181 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14182 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14183 (copy_text): Remove unused local var.
14185 * filelock.c (within_one_second): Now static.
14186 (lock_file_1): Rename local to avoid shadowing.
14188 * buffer.c (fix_overlays_before): Mark locals as initialized.
14189 (fix_start_end_in_overlays): Likewise. This function should be
14190 simplified by using pointers-to-pointers, but that's a different
14192 (switch_to_buffer_1): Now static.
14193 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14194 (report_overlay_modification): Rename locals to avoid shadowing.

14197 Fix pointer signedness issue.
14198 (sys_subshell): Mark local as volatile if checking for lint,
14199 to suppress a gcc -Wclobbered warning that does not seem to be right.
14200 (MAXPATHLEN): Define only if needed.
14202 * process.c (serial_open, serial_configure): Move decls from here ...
14203 * systty.h: ... to here, so that they can be checked.
14205 * fns.c (get_random, seed_random): Move extern decls from here ...
14206 * lisp.h: ... to here, so that they can be checked.
14208 * sysdep.c (reset_io): Now static.

14217 (describe_map_tree):
14218 Rename locals to avoid shadowing.
14220 * keyboard.c: Declare functions static if they are not used elsewhere.

14367 For example, without this patch (encode-time 0 0 0 1 1
14368 1152921504606846976) returns the obviously-bogus value (-948597
14369 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14370 reports time overflow. See
