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

404 not be usable in #if. This simplifies things.
406 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
408 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
410 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

415 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
416 Adjust to changes in lisp.h and emacs.c, by using

432 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
433 (gdb_USE_LSB_TAG): New enum constants.
434 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

437 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

441 Now enum constants, not macros, so they're visible to GDB.
442 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
443 more convenient now. All uses changed.
444 (VALMASK) [USE_LSB_TAG]: Also define in this case.

1321 (menu_separator_name_p):

1323 Prefer memcmp to strncmp when either will do.
1324 * nsterm.m: Include <ftoastr.h>.
1326 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1327 Prefer snprintf to strncpy.
1328 * nsterm.m (ns_term_init):
1329 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1330 * nsterm.m (ns_term_init):
1331 Avoid the need for strncpy, by using build_string or
1332 make_unibyte_string directly. Use dtoastr, not snprintf.
1333 * process.c (Fmake_network_process): Diagnose service names that
1334 are too long, rather than silently truncating them or creating
1335 non-null-terminated names.

1380 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1381 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1382 * lread.c (openp): Likewise.
1384 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1386 Avoid calls to strlen in path processing functions.
1387 * fileio.c (file_name_as_directory): Add comment. Change to add
1388 srclen argument and return the length of result. Adjust users
1390 (directory_file_name): Fix comment. Change to add srclen argument,
1391 swap 1st and 2nd arguments to obey the common convention. Adjust
1393 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1395 2012-07-10 Glenn Morris <rgm@gnu.org>
1397 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1398 Move PENDING_OUTPUT_COUNT definition to configure.
1400 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1401 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1402 * s/gnu.h (DATA_START): Move definitions to configure.
1404 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1405 We include usg5-4-common.h, which defines them both.
1407 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1408 O_RDONLY already includes it).
1410 Stop ns builds setting the EMACSLOADPATH environment variable.
1411 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1412 Now it does not set EMACSLOADPATH, just returns the load-path string.
1413 * nsterm.h: Update accordingly.
1414 * lread.c [HAVE_NS]: Include nsterm.h.
1415 (init_lread) [HAVE_NS]: Use ns_load_path.

1418 2012-07-09 Glenn Morris <rgm@gnu.org>
1420 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1421 since the included bsd-common.h does so.
1423 Stop ns builds setting the EMACSPATH environment variable.
1424 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1425 (ns_init_paths): Do not set EMACSPATH.
1426 * nsterm.h (ns_exec_path): Add it.
1427 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1430 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1432 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1434 * process.c (wait_reading_process_output): 'waitchannels' was unset
1435 when read_kbd || !NILP (wait_for_cell); fix this.
1437 Add GCC-style 'const' attribute to functions that can use it.
1438 * character.h (char_resolve_modifier_mask):
1439 * keyboard.h (make_ctrl_char):
1440 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1441 (init_character_once, next_almost_prime, init_fns, init_image)
1442 (flush_pending_output, init_sound):

1447 Declare the dummy function with ATTRIBUTE_CONST.
1448 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1449 Add decls with ATTRIBUTE_CONST.
1451 Minor improvements to make_formatted_string.
1452 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1453 where int is good enough, as vsprintf returns an int.
1454 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1456 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1458 Use make_formatted_string to avoid double length calculation.
1459 * lisp.h (make_formatted_string): New prototype.
1460 * alloc.c (make_formatted_string): New function.
1461 * buffer.c (Fgenerate_new_buffer_name): Use it.

1465 * frame.c (make_terminal_frame, set_term_frame_name)
1466 (x_report_frame_params): Likewise.

1481 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1483 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1485 Move marker debugging code under MARKER_DEBUG.
1486 * marker.c (MARKER_DEBUG): Move marker debugging code under
1487 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1488 for bootstrap with --enable-checking (~3x slowdown reported
1489 by Juanma Barranquero <lekktu@gmail.com>).
1490 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1492 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1494 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1495 See <http://bugs.gnu.org/11825#29>.
1497 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1499 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1500 has no font, use the frame's font. (Bug#11813)
1501 (display_line): Add commentary about displaying truncation glyphs
1503 (produce_special_glyphs): Move here from term.c.
1505 * term.c (produce_special_glyphs): Move to xdisp.c.
1507 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1510 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1512 * xdisp.c (display_line): Avoid warning about implicit declaration
1515 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1517 * lisp.h: Remove empty conditional.
1519 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1521 * lread.c (load_path_check): Now static.
1523 Fix some minor --with-ns problems found by static checking.
1524 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1525 (x_set_font) [!HAVE_X_WINDOWS]:
1526 * image.c (xpm_load_image) [HAVE_NS]:
1527 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1528 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1529 Remove unused local.
1530 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1531 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1532 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1533 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1534 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1535 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1536 Fix pointer signedness problem.
1537 * xfaces.c (FRAME_X_FONT_TABLE):
1538 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1540 2012-07-07 Glenn Morris <rgm@gnu.org>
1542 * lread.c (load_path_check): New function, split from init_lread.
1543 (init_lread): Reorganize. Motivation:
1544 If EMACSLOADPATH is set, check/warn about that rather than the
1545 defaults, which we are not going to use. Hence we can remove
1546 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1547 Don't warn if site-lisp directories are missing.
1548 If not installed, start from a blank load-path, since
1549 PATH_LOADSEARCH refers to the eventual installation directories.
1551 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1553 Support truncation and continuation glyphs on GUI frames, when
1554 fringes are disabled. (Bug#11832)
1555 * xdisp.c (init_iterator): Get dimensions of truncation and
1556 continuation glyphs even if on GUI frames. Adjust
1557 it->last_visible_x on GUI frames when the left or right fringes,
1558 or both, are absent.
1559 (start_display, move_it_in_display_line_to): Handle the case of a
1560 GUI frame without a fringe to display continuation or truncation
1562 (insert_left_trunc_glyphs): Support GUI frames: make sure
1563 truncation glyphs overwrite enough glyphs from the current line to
1564 have sufficient space in pixels.
1565 (display_line): Support truncation and continuation glyphs on GUI
1566 frames. If some spare pixels are left on the line after inserting
1567 the truncation glyphs, fill that space with a stretch glyph of a
1568 suitably computed width.
1570 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1571 produce_glyphs, to support GUI sessions.
1573 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1575 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1577 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1579 Do not require float-time's arg to fit in time_t (Bug#11825).
1580 This works better on hosts where time_t is unsigned, and where
1581 float-time is applied to the (negative) difference between two times.
1582 * editfns.c (decode_time_components): Last arg is now double *,
1583 not int *, and means to store all the result as a double, without
1584 worrying about whether the seconds part fits in time_t.
1585 All callers changed.
1586 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1587 All callers changed.
1588 (Ffloat_time): Do not fail merely because the specified time falls
1589 outside of time_t range.
1591 2012-07-07 Glenn Morris <rgm@gnu.org>
1593 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1608 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1609 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1610 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

1613 * xfont.c (compare_font_names): Redo to omit the need for casts.
1615 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1617 * xfns.c (Fx_change_window_property): Doc fix.
1618 * w32fns.c (Fx_change_window_property): Doc fix.
1620 * w32fns.c (Fx_window_property): Accept the same arguments as the
1621 X Windows version. Doc fix.
1622 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1624 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1625 Eli Zaretskii <eliz@gnu.org>
1627 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1628 Windows-specific code from nt/config.nt moved here.
1629 Obsolete settings removed.
1631 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1633 * process.c: Avoid unnecessary calls to gettime.
1634 (wait_reading_process_output): Don't get the time of day
1635 when gobbling data immediately and not waiting, as there's no need
1636 for it in that case. This removes a FIXME.
1638 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1640 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1641 is defined (Bug#11768).
1643 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1645 Fix marker debugging code.
1646 * marker.c (byte_char_debug_check): Do not perform the check
1647 if buffer is not multibyte.
1648 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1649 Call byte_char_debug_check with correct arguments.
1651 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1653 Compile marker debugging code only if ENABLE_CHECKING is defined.
1654 * marker.c (byte_char_debug_check, count_markers):
1655 Use only if ENABLE_CHECKING is defined.
1656 (byte_debug_flag): Remove.
1657 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1658 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1660 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1662 Avoid code repetition in marker-related functions.
1663 * marker.c (attach_marker): New function.
1664 (Fset_marker, set_marker_restricted, set_marker_both)
1665 (set_marker_restricted_both): Use it.
1666 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1667 Consistently rename charno to charpos.
1668 (marker_position): Add eassert.
1669 (marker_byte_position): Convert to eassert.

1688 * window.c (save_window_save): Likewise.
1690 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1692 Do not use Fdelete_overlay in delete_all_overlays
1693 to avoid redundant calls to unchain_overlay.
1694 * buffer.c (drop_overlay): New function.
1695 (delete_all_overlays, Fdelete_overlay): Use it.
1696 * minibuf.c (get_minibuffer): Fix comment.
1698 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1700 Port to OpenBSD 5.1 amd64.
1701 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1702 This is needed for OpenBSD, and should be harmless on all BSD systems.
1703 Also, include <sys/sysctl.h>, as it should be available on all
1704 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1705 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1706 use p_pid member, not kp_proc.pid.
1708 2012-07-06 Glenn Morris <rgm@gnu.org>
1710 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1712 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1714 More xmalloc and related cleanup.

1723 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1725 Omit needless casts involving void * pointers and allocation.
1726 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1727 as the former is more robust if P's type is changed.
1728 Prefer xzalloc to xmalloc + memset 0.
1729 Simplify malloc-or-realloc to realloc.
1730 Don't worry about xmalloc returning a null pointer.
1731 Prefer xstrdup to xmalloc + strcpy.
1732 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1734 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1735 alloca of a constant.
1737 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1739 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1740 hscroll is larger than the line width. Fixes long and futile
1741 looping inside extend_face_to_end_of_line (on a TTY) producing
1742 glyphs that are not needed and thrown away.
1744 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

1772 * xdisp.c (window_hscroll_limited): New function.
1773 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1774 coordinates when window's hscroll is set to insanely large
1777 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1779 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1844 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1846 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1847 This should be fixed in a better way; see Eli Zaretskii in
1848 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1849 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1851 * fileio.c (time_error_value): Rename from special_mtime.
1852 The old name's problems were noted by Eli Zaretskii in
1853 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1855 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1856 This variable's comment says Emacs needs at least one GDB-visible
1857 symbol of type enum pvec_type, to work around GDB problems.
1858 The symbol's value doesn't matter.
1860 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1861 that causes compilation to fail on pre-C99 compilers.
1863 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1865 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1866 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1868 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1870 * buffer.c (init_buffer_once): Fix initialization of
1871 headers for buffer_defaults and buffer_local_symbols.
1872 Reported by Juanma Barranquero <lekktu@gmail.com>.
1874 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1876 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1877 * lisp.h (enum pvec_type): Use fewer bits.
1878 (PSEUDOVECTOR_SIZE_BITS): New constant.
1879 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1880 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1881 change in pvec_type.
1882 (PSEUDOVECTOR_TYPEP): New macro.
1883 (TYPED_PSEUDOVECTORP): Use it.
1884 * fns.c (internal_equal): Adapt code to extract pvectype.
1885 * emacs.c (gdb_pvec_type): Update type.
1886 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1887 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1888 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1889 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1890 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1891 abusing vector->header.next.nbytes.
1892 (live_vector_p): Use PVEC_TYPE.
1893 (mark_object): Adapt code to extract pvectype. Use switch.
1895 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1897 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1898 Tighten new eassert a bit.
1900 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1902 Fix compilation with --enable-gcc-warnings and -O1
1904 * doprnt.c (doprnt): Change type of tem to int, initialize
1905 to avoid compiler warning. Add eassert.
1906 * search.c (simple_search): Initialize match_byte to avoid
1907 compiler warning. Add eassert.
1909 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1911 Avoid weird behavior with large horizontal scrolls.
1912 Without this change, for example, large hscroll values would
1913 mess up Emacs's display on Fedora 15 x86, presumably due to
1914 overflows in int calculations in the display code.
1915 Also, if buffers had long lines, Emacs would freeze.
1916 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1917 (set_window_hscroll): New function, containing the old guts of
1918 Fset_window_hscroll. Return the clipped value.
1919 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1920 This avoids the need to check against PTRDIFF_MAX.
1922 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1924 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1926 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1928 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1930 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1931 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1932 since GCC 4.4.6 issues a bogus warning for them.
1934 Fix bugs in file timestamp newness comparisons.
1935 * fileio.c (Ffile_newer_than_file_p):
1936 * lread.c (Fload): Use full timestamp resolution of files,
1937 not just the 1-second resolution, so that files that are only
1938 slightly newer still count as newer.
1939 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1940 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1942 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1944 * fileio.c: Improve handling of file time marker. (Bug#11852)
1945 (special_mtime): New function.
1946 (Finsert_file_contents, Fverify_visited_file_modtime):
1947 Use it to set special mtime values consistently.
1949 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1951 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1952 marker for non-existing file. (Bug#11852)
1954 2012-07-03 Glenn Morris <rgm@gnu.org>
1956 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1957 and did not make it into globals.h).
1959 2012-07-03 Tom Tromey <tromey@redhat.com>
1961 * window.c (Fset_window_margins, Fset_window_fringes)
1962 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1963 * textprop.c (Fprevious_property_change): No longer static.
1964 * syntax.c (Fsyntax_table_p): No longer static.
1965 * process.c (Fget_process, Fprocess_datagram_address): No longer
1967 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
1968 * keyboard.c (Fcommand_execute): No longer static.
1970 * insdel.c (Fcombine_after_change_execute): No longer static.
1971 * image.c (Finit_image_library): No longer static.

1973 * eval.c (Ffetch_bytecode): No longer static.
1974 * editfns.c (Fuser_full_name): No longer static.
1975 * doc.c (Fdocumentation_property, Fsnarf_documentation):
1977 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
1979 * dired.c (Ffile_attributes): No longer static.
1980 * composite.c (Fcomposition_get_gstring): No longer static.
1981 * callproc.c (Fgetenv_internal): No longer static.
1983 * ccl.h: Remove EXFUNs.
1984 * buffer.h: Remove EXFUNs.
1985 * dispextern.h: Remove EXFUNs.
1986 * intervals.h: Remove EXFUNs.
1987 * fontset.h: Remove EXFUN.
1988 * font.h: Remove EXFUNs.
1989 * dosfns.c (system_process_attributes): Remove EXFUN.
1990 * keymap.h: Remove EXFUNs.
1991 * lisp.h: Remove EXFUNs.
1992 * w32term.h: Remove EXFUNs.
1993 * window.h: Remove EXFUNs.
1994 * xsettings.h: Remove EXFUN.
1995 * xterm.h: Remove EXFUN.
1997 2012-07-03 Glenn Morris <rgm@gnu.org>
1999 * lisp.h (Frandom): Make it visible to C.
2000 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2001 buffer for invisible buffers. (Bug#1229)
2003 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2005 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2006 values which aren't power of 2.
2007 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2008 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2011 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2013 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2015 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2017 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2019 * alloc.c (allocate_vector_block): Remove redundant
2020 calls to mallopt if DOUG_LEA_MALLOC is defined.
2021 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2022 avoid calls to mallopt if zero_vector is returned.
2024 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2026 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2027 is enabled, avoid dereferencing NULL current_sblock if
2030 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2032 Cleanup basic buffer management.
2033 * buffer.h (struct buffer): Change layout to use generic vector
2034 marking code. Fix some comments. Change type of 'clip_changed'
2035 to bitfield. Remove unused #ifndef old.
2036 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2037 (GET_OVERLAYS_AT): Fix indentation.
2038 (for_each_per_buffer_object_at): New macro.
2039 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2040 (Fbuffer_local_variables): Use it.
2041 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2042 * alloc.c (allocate_buffer): Adjust to match new layout of
2043 struct buffer. Fix comment.
2044 (mark_overlay): New function.

2046 Lisp area of struct buffer.
2047 (mark_object): Use it. Adjust marking of misc objects
2048 and related comments.
2050 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2052 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2053 wrapper that is not needed because the wrapped code is a no-op (zero
2054 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2055 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2057 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2059 * alloc.c (mark_buffer): Simplify. Remove prototype.
2060 (mark_object): Add comment. Reorganize marking of vector-like
2061 objects. Use CHECK_LIVE for all vector-like objects except buffers
2062 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2063 redundant calls to mark_vectorlike for bool vectors.
2065 2012-06-30 Glenn Morris <rgm@gnu.org>
2067 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2069 * epaths.in (PATH_SITELOADSEARCH): New.
2070 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2071 This is rather than relying on --enable-locallisppath elements
2072 having "site-lisp" in their names. (Bug#10208#25, 11658)
2074 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2076 * w32proc.c (sys_select): Accept and ignore one more argument.
2078 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2080 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2081 (pselect) [!MS_DOS]: Redirect to sys_select.
2083 * sysdep.c: Don't include dos.h and dosfns.h.
2085 * process.c (sys_select):
2086 * msdos.c (sys_select): Accept one more argument and ignore it.
2088 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2089 adapt data types and code to that.
2092 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2093 which clashes with the gnulib function of the same name.
2095 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2097 * font.c (font_style_to_value, font_style_symbolic)
2098 (font_prop_validate_style): Add type checks for values in
2101 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2103 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2106 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2108 * xdisp.c (try_window_id): Undo last change.
2110 * w32.c (getwd): Adjust commentary about startup_dir.
2111 (init_environment): Always call sys_access, even in non-MSVC
2112 builds. Don't chdir to the directory of the Emacs executable.
2113 This undoes code from 1997 which was justified by the need to
2114 "avoid conflicts when removing and renaming directories". But its
2115 downside was that every relative file name was being interpreted
2116 relative to the directory of the Emacs executable, which can never
2117 be TRT. In particular, it broke sys_access when called with
2118 relative file names.
2119 (sys_access): Map GetLastError to errno.
2121 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2123 * window.h (struct window): Change type of 'fringes_outside_margins'
2124 to bitfield. Fix comment. Adjust users accordingly.
2125 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2127 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2130 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2132 * gnutls.c (emacs_gnutls_handshake):
2133 Add QUIT to make the loop interruptible.
2135 2012-06-29 Glenn Morris <rgm@gnu.org>
2137 * charset.c (init_charset): Make lack of etc/charsets fatal.
2139 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2141 * editfns.c (region_limit): Fix type mismatch.
2143 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2145 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2146 undefined. Convert from xassert to eassert.
2147 * nsmenu.m: Convert from xassert to eassert.
2148 * nsterm.m: Likewise.
2150 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2152 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2154 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2156 Avoid integer overflow on scroll-left and scroll-right.
2157 * window.c (HSCROLL_MAX): New macro.
2158 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2159 overflow when requested scroll falls outside ptrdiff_t range.
2161 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2163 * window.h (struct window): Change type of 'hscroll',
2164 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2165 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2166 Adjust users accordingly.
2167 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2168 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2169 from EMACS_INT to ptrdiff_t.
2170 (make_window): Omit redundant initialization.
2172 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2174 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2176 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2178 * window.h (struct window): Change type of 'use_time' and
2179 'sequence_number' from Lisp_Object to int.
2180 * frame.c (make_frame): Adjust users accordingly.
2181 * print.c (print_object): Likewise.
2182 * window.c (select_window, Fwindow_use_time, make_parent_window)
2183 (make_window): Likewise.
2185 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2187 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2188 enabled with --enable-checking=[all,glyphs] configure option.
2189 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2190 adjust comments accordingly.
2191 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
2192 undefined, adjust comments accordingly.

2202 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2204 Generalize run-time debugging checks.
2205 * dispextern.h (XASSERTS): Remove.
2206 * fontset.c (xassert): Remove.
2207 Convert from xassert to eassert.

2239 * alloc.c (allocate_string_data): Remove dead code.
2240 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2241 avoid GCC warning about unused macro.
2243 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2245 * alloc.c (allocate_string): Omit intervals initialization.
2246 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2247 as in make_pure_string and make_pure_c_string.
2249 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2251 * alloc.c (allocate_string): Fix last change.
2253 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2255 * alloc.c (allocate_string): Remove two redundant calls
2256 to memset, add explicit initialization where appropriate.

2286 * alloc.c (allocate_window): Zero out non-Lisp part of newly
2288 (allocate_process): Likewise for new process.

2303 * alloc.c: Remove build_string.
2304 * lisp.h: Define build_string as static inline. This provides
2305 a better opportunity to optimize away calls to strlen when the
2306 function is called with compile-time constant argument.
2307 * image.c (imagemagick_error): Convert to build_string.
2308 * w32proc.c (sys_spawnve): Likewise.
2309 * xterm.c (x_term_init): Likewise.
2311 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2313 Use sprintf return value instead of invoking strlen on result.
2314 In the old days this wasn't portable, since some sprintf
2315 implementations returned char *. But they died out years ago and
2316 Emacs already assumes sprintf returns int.
2317 Similarly for float_to_string.
2318 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2319 * ccl.c (ccl_driver):
2320 * character.c (string_escape_byte8):
2321 * data.c (Fnumber_to_string):
2322 * doprnt.c (doprnt):
2323 * print.c (print_object):
2324 * xdisp.c (message_dolog):
2325 * xfns.c (syms_of_xfns):
2326 Use sprintf or float_to_string result to avoid need to call strlen.
2327 * data.c (Fnumber_to_string):
2328 Use make_unibyte_string, since the string must be ASCII.
2329 * lisp.h, print.c (float_to_string): Now returns int length.
2330 * term.c (produce_glyphless_glyph):
2331 Use sprintf result rather than recomputing it.
2333 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2334 * Makefile.in (ALL_CFLAGS):

2425 Remove unnecessary forward decls.
2427 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2431 * dispnew.c (Fsleep_for, sit_for):
2432 * keyboard.c (kbd_buffer_get_event):
2433 * process.c (Faccept_process_output):
2434 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2435 This improves on the previous patch, which introduced a bug
2436 when time_t is unsigned and as wide as intmax_t.
2437 See <http://bugs.gnu.org/9000#51>.
2439 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2468 language ID in the event parameters.
2470 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2500 Don't assume EMACS_TIME and struct timeval are the same type.
2502 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2504 Support higher-resolution time stamps (Bug#9000).
2505 The time stamps are only nanosecond-resolution at the C level,
2506 since that's the best that any real-world system supports now.
2507 But they are picosecond-resolution at the Lisp level, as that's
2508 easy, and leaves room for future OS improvements.
2510 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2513 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2514 Don't get current time unless it's needed.
2516 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2517 now provides it if it's absent.
2518 (start_atimer): Port to higher-res time stamps.
2519 Check for time stamp overflow. Don't get current time more
2520 often than is needed.
2522 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2523 Include systime.h, not time.h.
2524 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2526 * dired.c: Include stat-time.h.
2527 (Ffile-attributes): File times now have higher resolution.

2530 (struct image): Timestamp now has higher resolution.
2532 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2533 has at least microseconds now. All uses removed.
2534 (update_frame, update_single_window, update_window, update_frame_1)
2535 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2537 * editfns.c (time_overflow): Now extern.
2538 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2539 (float-time, Fformat_time_string, Fcurrent_time_string)
2540 (Fcurrent_time_zone): Accept and generate higher-resolution
2542 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2543 (decode_time_components, lisp_seconds_argument): New functions.
2544 (make_time): Now static.
2545 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2546 Report an error if the time is invalid, rather than having the caller
2549 * fileio.c: Include <stat-time.h>
2550 (Fcopy_file): Copy higher-resolution time stamps.
2551 Prefer to set the time stamp via a file descriptor if that works.
2552 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2553 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2554 (Fvisited_file_modtime, Fset_visited_file_modtime):
2555 Support higher-resolution time stamps.
2557 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2559 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2561 * image.c (prepare_image_for_display, clear_image_cache)
2562 (lookup_image): Port to higer-resolution time stamps.
2564 * keyboard.c (start_polling, bind_polling_period):
2565 Check for time stamp overflow.
2566 (read_char, kbd_buffer_get_event, timer_start_idle)
2567 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2568 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2569 Port to higher-resolution time stamps. Do not assume time_t is signed.
2570 (decode_timer): New function. Timers are now vectors of length 9,
2571 not 8, to accommodate the picosecond component.
2572 (timer_check_2): Use it.
2574 * nsterm.m (select_timeout, timeval_subtract): Remove.
2575 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2576 as they're a bit more accurate and handle overflow better.
2577 (ns_select): Change prototype to be compatible with pselect.
2578 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2579 * nsterm.h (ns_select): Adjust prototype.
2581 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2582 us-resolution time stamps.
2583 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2585 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2587 * lisp.h (time_overflow): New decl.
2588 (wait_reading_process_output): First arg is now intmax_t, not int,
2589 to accommodate larger waits.
2591 * process.h (struct Lisp_Process.read_output_delay):
2592 Now counts nanoseconds, not microseconds.
2593 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2595 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2596 (wait_reading_process_output):
2597 Port to ns-resolution time stamps.
2598 (Faccept_process_output, wait_reading_process_output):
2599 Check for time stamp overflow. Do not assume time_t is signed.
2600 (select_wrapper): Remove; we now use pselect.
2601 (Fprocess_attributes): Now generates ns-resolution time stamps.
2603 * sysdep.c: Include utimens.h. Don't include utime.h
2604 or worry about struct utimbuf; gnulib does that for us now.
2605 (gettimeofday): Remove; gnulib provides a substitute.
2606 (make_timeval): New function.
2607 (set_file_times): Now sets ns-resolution time stamps.
2608 New arg FD; all uses changed.
2609 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2610 (system_process_attributes):
2611 Now returns ns-resolution time stamp. All uses changed.
2612 Check for time stamp overflow.
2614 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2615 provides a substitute now.
2617 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2618 since it guarantees struct timespec.
2619 (EMACS_TIME): Now struct timespec, so that we can support
2620 ns-resolution time stamps.
2621 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2622 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2623 (EMACS_USECS): Remove.
2624 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2625 so multiply the arg by 1000 before storing it.
2626 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2628 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2629 Port to ns-resolution time stamps.
2630 (EMACS_TIME_NEG_P): Remove; replaced by....
2631 (EMACS_TIME_SIGN): New macro.
2632 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2633 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2634 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2635 (make_timeval, make_lisp_time, decode_time_components): New decls.
2636 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2637 that it mishandled time_t overflow. You can't compare by subtracting!
2638 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2639 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2641 * term.c: Include <sys/time.h>.
2642 (timeval_to_Time): New function, for proper overflow wraparound.
2643 (term_mouse_position, term_mouse_click): Use it.
2645 * undo.c (record_first_change): Support higher-resolution time stamps
2647 (Fprimitive_undo): Use them when restoring time stamps.
2649 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2650 (w32_get_internal_run_time):
2651 Port to higher-resolution Emacs time stamps.
2652 (ltime): Now accepts single 64-bit integer, as that's more convenient
2655 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2657 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2658 for compatibility with pselect. Support ns-resolution time stamps.
2660 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2662 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2663 Check for time stamp overflow, and support ns-resolution time stamps.
2665 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2666 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2667 (timeval_subtract): Remove; no longer needed.
2668 (XTflash, XTring_bell, x_wait_for_event):
2669 Port to ns-resolution time stamps. Don't assume time_t is signed.
2671 2012-06-22 Chong Yidong <cyd@gnu.org>
2673 * xdisp.c (x_consider_frame_title): Revert last change.
2675 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2677 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2678 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2679 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2680 staticidx goes up to 1597 out of 1600 = 0x640.)
2682 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2684 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2685 Otherwise, the umask might be mistakenly 0 while handling input signals.
2687 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2689 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

2695 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2696 access to `contents' member of Lisp_Vector objects with AREF and ASET
2699 2012-06-19 Chong Yidong <cyd@gnu.org>
2701 * frame.c (delete_frame): When selecting a frame on a different
2702 text terminal, do not alter the terminal's top-frame.

2706 (unwind_format_mode_line): Restore them.
2707 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2709 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2710 since tty frames can be explicitly named.
2711 (prepare_menu_bars): Likewise.
2713 * term.c (Ftty_top_frame): New function.
2715 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2717 Port byte-code-meter to modern targets.
2718 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2719 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2720 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2721 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2722 (METER_1, METER_2): Simplify.
2724 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2726 * data.c (Fdefalias): Return `symbol' (bug#11686).
2728 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2730 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2731 gets killed during executing of this function (Bug#11665).
2732 Try to always return Qt when the buffer has been actually killed.
2733 (Vkill_buffer_query_functions): In doc-string say that functions
2734 run by this hook should not change the current buffer.
2736 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2738 Fix recently-introduced process.c problems found by static checking.
2739 * process.c (write_queue_push, write_queue_pop, send_process):

2742 (send_process): Remove unused local.
2744 2012-06-17 Chong Yidong <cyd@gnu.org>

2747 frames that are not on top.
2749 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
2751 * process.c (make_process): Initialize write_queue.
2752 (write_queue_push, write_queue_pop): New functions.
2753 (send_process): Use them to maintain correct ordering of process
2756 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2758 * lisp.h (eassert): Assume C89 or later.
2759 This removes the need for CHECK.
2760 (CHECK): Remove. Its comments about always evaluating its
2761 argument were confusing, as 'eassert' typically does not evaluate
2764 * coding.c (produce_chars): Use ptrdiff_t, not int.
2766 * xterm.c (x_draw_underwave): Check for integer overflow.
2767 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
2769 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
2771 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

2952 code works fine either way, and efficiency is not a concern here,
2953 as the union type is for debugging, not for production.
2954 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2955 Use an inline function on all platforms when using the union type,
2956 since this is simpler and 'static inline' can be used portably

3100 * doprnt.c (doprnt): Truncate multibyte char correctly.
3101 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3102 would mishandle a string argument "Xc" if X was a multibyte

3157 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3158 Convert pctcpu and pctmem to Lisp float properly.

3163 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

3178 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3179 fields from Lisp_Object to bitfield. Adjust users accordingly.

3187 and 'double' in a couple of places.
3189 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3191 * xdisp.c (handle_stop): Detect whether we have overlay strings
3192 loaded by testing it->current.overlay_string_index to be
3193 non-negative, instead of checking whether n_overlay_strings is
3194 positive. (Bug#11587)
3196 2012-05-31 Chong Yidong <cyd@gnu.org>
3198 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3204 * search.c (search_buffer): Remove calls to
3205 r_alloc_inhibit_buffer_relocation, as it is now called by
3206 maybe_unify_char, which was the cause of relocation of buffer text
3209 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3211 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3212 for the duration of call to load_charset, to avoid problems with
3213 callers of maybe_unify_char that access buffer text through C
3216 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3217 decrement the inhibition flag, instead of just setting or
3220 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3222 Remove obsolete '#define static' cruft.
3223 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3224 This #undef was "temporary" in 2000; it is no longer needed

3226 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3227 (gray_bitmap_bits): Remove; no longer needed.
3228 All uses replaced with definiens.

3272 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3273 Bug#9642, but explicitly check that the buffer the overlay would
3274 be moved to is live and rearrange lines to make sure that errors
3275 will not put the overlay in an inconsistent state.
3276 (Fdelete_overlay): Cosmetics.
3278 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3280 * w32term.c (my_bring_window_to_top): New function.

3282 could be different from the original one.
3283 Call my_bring_window_to_top instead of my_set_foreground_window.
3286 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3287 by calling BringWindowToTop.
3289 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3290 (WM_EMACS_END): Increase by one.
3292 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3294 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3295 This avoids undefined behavior that might cause the eassert
3296 to not catch an out-of-range value.
3298 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3300 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3310 when referring to sectname field in printf format.
3312 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3314 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3315 Only r_alloc_inhibit_buffer_relocation needed to be added;
3316 the others were already declared.
3318 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3319 before checking whether it's out of range. Put the check inside
3321 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3323 2012-05-27 Ken Brown <kbrown@cornell.edu>
3325 * callproc.c (Fcall_process): Restore a line that was accidentally
3326 commented out in the 2011-02-13 change (bug#11547).
3328 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3330 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3331 defined on ralloc.c.
3333 * buffer.c [REL_ALLOC]: Remove prototypes of
3334 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3335 they are now on lisp.h.
3337 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3339 * search.c (search_buffer): Use it to inhibit relocation of buffer
3340 text while re_search_2 is doing its job, because re_search_2 is
3341 passed C pointers to buffer text. (Bug#11519)
3343 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3346 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3347 state after an additional call to move_it_in_display_line_to, keep
3348 the values of it->max_ascent and it->max_descent found for the
3350 (pos_visible_p): Revert the comparison against bottom_y to what it
3351 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3354 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3356 Fix coding-related core dumps with gcc -ftrapv.
3357 The code was computing A - B, where A and B are pointers, and B is
3358 random garbage. This can lead to core dumps on platforms that
3359 have special pointer registers, and it also leads to core dumps on
3360 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3361 A - B only when B is initialized properly.
3362 * coding.c (coding_set_source, coding_set_destination): Return void.
3363 (coding_change_source, coding_change_destinations): New functions,
3364 with the old behaviors of coding_set_source and coding_set_destination.
3365 All callers that need an offset changed to use these new functions.
3367 2012-05-26 Glenn Morris <rgm@gnu.org>
3369 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3371 2012-05-26 Eli Zaretskii <eliz@gnu.org>

3374 * xdisp.c (draw_row_with_mouse_face):
3375 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3377 * w32console.c: Include window.h.
3378 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3380 (initialize_w32_display): Initialize mouse-highlight data.
3382 * w32inevt.c: Include termchar.h and window.h.
3383 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3384 moves, call note_mouse_highlight. If help_echo changed, call
3385 gen_help_event to produce help-echo message in the echo area.
3386 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3389 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3391 * lread.c (read1): Simplify slightly to avoid an overflow warning
3392 with GCC 4.7.0 on x86-64.
3394 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3396 * bidi.c (bidi_mirror_char): Revert last change: an int is
3397 definitely wide enough here.
3399 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3401 Fix integer width and related bugs (Bug#9874).

3409 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3411 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3412 (allocate_pseudovector):
3413 Use int, not EMACS_INT, where int is wide enough.
3414 (inhibit_garbage_collection, Fgarbage_collect):
3415 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3416 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3417 int might not be wide enough.
3418 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3432 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3433 (Foverlay_recenter, last_overlay_modification_hooks_used)
3434 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3435 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3436 (validate_region): Omit unnecessary test for b <= e,
3437 since that's guaranteed by the previous test.
3438 (adjust_overlays_for_delete): Avoid pos + length overflow.
3439 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3440 (report_overlay_modification):
3441 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3442 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3443 Omit pointer cast, which isn't needed anyway, and doesn't work
3444 after the EMACS_INT -> ptrdiff_t change.
3445 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3446 * buffer.h: Adjust decls to match defn changes elsewhere.

3451 not int, to avoid needless 32-bit limit on 64-bit hosts.
3452 (exec_byte_code): Use tighter memory-full test, one that checks
3453 for alloca overflow. Don't compute the address of the object just
3454 before an array, as that's not portable. Use EMACS_INT, not
3455 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3456 * callint.c (Fcall_interactively):
3457 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3468 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3469 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3470 (casify_object): Avoid integer overflow when overallocating buffer.
3471 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3472 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3473 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3474 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3475 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3476 integers are now checked earlier. All uses replaced with XINT.
3478 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3479 For CCL_MapSingle, check that content and value are in int range.
3480 (ccl_driver, Fregister_code_conversion_map):
3481 Check that Vcode_version_map_vector is a vector.
3482 (resolve_symbol_ccl_program): Check that vector header is in range.
3483 Always copy the vector, so that we can check its contents reliably
3484 now rather than having to recheck each instruction as it's being
3485 executed. Check that vector words fit in 'int'.
3486 (ccl_get_compiled_code, Fregister_ccl_program)
3487 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3488 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3489 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3490 contents are in range.
3491 (Fccl_execute_on_string): Check that status is in range.
3492 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3493 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3494 Accept and return EMACS_INT, not int, because callers can pass values
3496 (c_string_width, strwidth, lisp_string_width, chars_in_text)

3500 (string_escape_byte8, Fget_byte):
3501 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3502 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3503 avoid mishandling large integers.
3504 * character.h: Adjust decls to match defn changes elsewhere.

3513 (Fdefine_charset_internal): Check ranges here, more carefully.
3514 Don't rely on undefined behavior with signed left shift overflow.
3515 Don't assume unsigned int fits into fixnum, or that fixnum fits
3516 into unsigned int. Don't require max_code to be a valid fixnum;
3517 that's not true for gb10830 4-byte on a 32-bit host. Allow
3518 invalid_code to be a cons, for the same reason. Require code_offset
3519 to be a character. Avoid int overflow if max_char is close
3521 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3522 this is intended anyway and avoids some undefined behavior.
3523 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3524 INDEX_TO_CODE_POINT, as that's what it expects.
3525 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3526 * charset.h (DECODE_CHAR): Return int, not unsigned;
3527 this is what was intended anyway, and it avoids undefined behavior.
3528 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3529 integer-overflow issues.
3530 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3531 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3532 where the argument is EMACS_INT, and this behavior is not intended.
3533 * chartab.c (Fmake_char_table, Fset_char_table_range)
3534 (uniprop_get_decoder, uniprop_get_encoder):
3535 Don't assume fixnum fits in int.
3536 * cmds.c (move_point): New function, that does the gist of
3537 Fforward_char and Fbackward_char, but does so while checking
3538 for integer overflow more accurately.
3539 (Fforward_char, Fbackward_char): Use it.
3540 (Fforward_line, Fend_of_line, internal_self_insert)
3541 (internal_self_insert):
3542 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3543 Fix a FIXME, by checking for integer overflow when calculating
3544 target_clm and actual_clm.

3579 Don't access memory outside of the args array.
3580 (Fdefine_coding_system_internal): Check for charset-id overflow.

4341 already have overlays loaded.
4342 (handle_single_display_spec): Before returning without displaying
4343 fringe bitmap, synchronize the bidi iterator with the main display
4344 iterator, by calling iterate_out_of_display_property.
4345 (iterate_out_of_display_property): Detect buffer iteration by
4346 testing that it->string is a Lisp string.
4347 (get_next_display_element): When the current object is exhausted,
4348 and there's something on it->stack, call set_iterator_to_next to

4351 proceed to consider_string_end without incrementing string
4352 position. Don't increment display vector index past the end of
4353 the display vector. (Bug#11417)
4354 (pos_visible_p): Don't report a position visible when move_it_to
4355 stopped at the last line of window, which happens to be scanned
4356 backwards by the bidi iteration. (Bug#11464)
4358 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4360 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4361 and right-margin display specs even if the spec is invalid or we
4362 are on a TTY, and thus unable to display on the fringes.
4363 That's because the text with the property will not be displayed anyway,
4364 so we need to signal to the caller that this is a "replacing"
4365 display spec. This fixes display when the spec is invalid or we
4368 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4370 * unexaix.c (make_hdr): Fix typo in prototype.

4415 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4417 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4418 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4419 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4420 Initialize xd_registered_buses.
4422 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4424 Untag more efficiently if USE_LSB_TAG.
4425 This is based on a proposal by YAMAMOTO Mitsuharu in
4426 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4427 For an admittedly artificial (nth 8000 longlist) benchmark on
4428 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4429 Emacs's overall text size by 1%.
4430 * lisp.h (XUNTAG): New macro.
4431 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4432 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4433 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4434 * eval.c (Fautoload):
4435 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4436 * frame.h (XFRAME): Use XUNTAG.
4438 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4439 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4440 Remove unportable assumptions about print widths of types like
4442 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4443 intptr_t when converting between pointer and integer, to avoid GCC
4444 warnings about wrong width.
4446 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4448 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4449 stack for each reader_thread, instead of defaulting to 8MB
4450 determined by the linker. This avoids failures in creating
4451 subprocesses on Windows 7, see the discussion in this thread:
4452 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4454 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4456 Fix up display of the *Minibuf-0* buffer in the mini window.
4457 * keyboard.c (read_char): Don't clear the echo area if there's no
4459 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4460 contents of *Minibuf-0*) if there's no message displayed in its stead.
4462 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4464 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4467 2012-05-06 Chong Yidong <cyd@gnu.org>
4469 * lisp.mk (lisp): Update.
4471 2012-05-05 Jim Meyering <meyering@redhat.com>
4473 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4475 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4477 * data.c (PUT_ERROR): New macro.
4478 (syms_of_data): Use it. Add new error type `user-error'.
4479 * undo.c (user_error): New function.
4480 (Fprimitive_undo): Use it.
4481 * print.c (print_error_message): Adjust print style for `user-error'.
4482 * keyboard.c (user_error): New function.
4483 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4485 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4487 Do not limit current-time-string to years 1000..9999.
4488 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4489 (Fcurrent_time_string): Support any year that is supported by the
4490 underlying localtime representation. Don't use asctime, as it
4491 has undefined behavior for years outside the range -999..9999.
4493 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4495 Fix race conditions involving setenv, gmtime, localtime, asctime.
4496 Without this fix, interrupts could mess up code that uses these
4497 nonreentrant functions, since setting TZ invalidates existing
4498 tm_zone or tzname values, and since most of these functions return
4499 pointers to static storage.
4500 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4501 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4502 Grow the critical sections to include not just invoking
4503 localtime/gmtime, but also accessing these functions' results
4504 including their tm_zone values if any, and any related TZ setting.
4505 (format_time_string): Last arg is now struct tm *, not struct tm **,
4506 so that the struct tm is saved in the critical section.
4507 All callers changed. Simplify allocation of initial buffer, partly
4508 motivated by the fact that memory allocation needs to be outside
4509 the critical section.
4511 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4513 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4514 with RESET_INTERVAL.
4516 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4517 Remove duplicated buffer name initialization.
4519 2012-05-02 Jim Meyering <jim@meyering.net>
4521 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4523 * xfns.c (x_window): Use xstrdup (Bug#11375).
4525 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4527 * xdisp.c (pos_visible_p): If already at a newline from the
4528 display string before the 'while' loop, don't walk back the glyphs
4529 from it3.glyph_row. Solves assertion violation when the display
4530 string begins with a newline (egg.el). (Bug#11367)
4532 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4534 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4537 2012-05-01 Glenn Morris <rgm@gnu.org>
4539 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4540 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4541 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4542 All were removed before 23.1.
4544 * dispnew.c: Remove HAVE_LIBNCURSES test;
4545 it is always true on relevant platforms.
4547 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4548 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4550 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4552 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4554 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4555 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4558 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4560 Do not avoid creating empty evaporating overlays (Bug#9642).
4561 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4562 That is, do not delete an evaporating overlay if it becomes
4563 empty after its bounds are adjusted to fit within its buffer.
4564 This fix caused other problems, and I'm reverting it until we get
4565 to the bottom of them.
4567 2012-04-27 Chong Yidong <cyd@gnu.org>
4569 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4571 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4573 * xdisp.c (pos_visible_p): If the window start position is beyond
4574 ZV, start the display from buffer beginning. Prevents assertion
4575 violation in init_iterator when the minibuffer window is scrolled
4578 * window.c (window_scroll_pixel_based): Likewise.
4580 2012-04-27 Chong Yidong <cyd@gnu.org>
4582 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4584 2012-04-27 Glenn Morris <rgm@gnu.org>
4586 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4587 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4589 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4591 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4592 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4594 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4596 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4597 display element, check also the underlying string or buffer
4598 character. (Bug#11341)
4600 * w32menu.c: Include w32heap.h.
4601 (add_menu_item): If the call to AppendMenuW (via
4602 unicode_append_menu) fails, disable Unicode menus only if we are
4603 running on Windows 9X/Me.
4605 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4607 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4608 (xgetint): Add missing shift for LSB tags.
4610 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4612 * keyboard.c (read_char): Don't wipe echo area for select window
4613 events: These might get delayed via `mouse-autoselect-window'
4616 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4618 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4619 manipulation of :loaded-from data.
4621 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4623 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4624 now a cons (bug#11311).
4626 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4628 Do not create empty overlays with the evaporate property (Bug#9642).
4629 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4630 if it becomes empty after its bounds are adjusted to fit within
4631 its buffer. Without this fix, in a nonempty buffer (let ((o
4632 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4633 yields an empty overlay that has the evaporate property, which is
4634 not supposed to happen.
4636 Fix minor GTK3 problems found by static checking.
4637 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4638 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4639 (struct _EmacsFixedClass, emacs_fixed_get_type):

4647 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4648 (EMACS_FIXED_GET_CLASS): Remove; unused.
4649 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4651 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4652 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4654 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4656 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4657 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4658 (__malloc_size_t, __malloc_ptrdiff_t):
4659 Remove. All uses removed, replaced by the definiens if needed,
4660 since we can assume C89 or better now.
4661 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4662 (protect_malloc_state, align, get_contiguous_space)
4663 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4669 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4670 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4671 Define using prototypes, not old style.
4672 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4673 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4674 (align): Don't assume that signed integer overflow wraps around.
4675 Omit unused local var.
4676 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4677 (_free_internal_nolock, memalign, mallochook, reallochook):

4683 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4685 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

4736 * alloc.c: Handle unusual debugging option combinations.
4737 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4738 since the two debugging options are incompatible.

4751 * sysdep.c [__FreeBSD__]: Minor cleanups.
4752 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4753 Use Emacs indenting style more consistently. Avoid some casts.
4754 Use 'double' consistently rather than mixing 'float' and 'double'.

4793 row, return zero immediately.
4794 (try_cursor_movement): If inside continuation line, don't back up
4795 farther than the first row after the header line, if any.
4796 Don't consider the header-line row as "partially visible", even if
4797 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4799 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4847 (r_alloc_sbrk): Now static.
4849 Improve ralloc.c interface checking.
4850 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

4852 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
4853 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
4854 [REL_ALLOC]: ... to here, to check interface.
4855 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4856 Remove decls. This fixes an "It stinks!".
4858 * alloc.c (which_symbols): Fix alignment issue / type clash.
4860 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4862 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
4863 (struct Lisp_Misc_Any): Likewise.
4864 (struct Lisp_Free): Likewise.
4865 * alloc.c (union aligned_Lisp_Symbol): Define.
4866 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
4867 aligned_Lisp_Symbol instead of struct Lisp_Symbol.

4869 (MARKER_BLOCK_SIZE, struct marker_block): Use union
4870 aligned_Lisp_Misc instead of union Lisp_Misc.
4871 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
4873 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4875 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4876 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4877 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4878 * s/netbsd.h, s/sol2-6.h:
4879 Remove definition of GC_MARK_STACK, since the default now works.
4880 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4881 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4882 no longer the default.
4883 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4885 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4887 * lread.c (lisp_file_lexically_bound_p):
4888 Fix hang at ";-*-\n" (bug#11238).
4890 2012-04-14 Eli Zaretskii <eliz@gnu.org>
4892 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
4893 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
4895 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
4897 * nsterm.m (constrainFrameRect): Always constrain when there is only
4898 one screen (Bug#10962).
4900 2012-04-13 Ken Brown <kbrown@cornell.edu>
4902 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

4908 2012-04-11 Daniel Colascione <dancol@dancol.org>
4910 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4911 against is gone. It's better to use vfork now so that when Cygwin
4912 gains a new, working vfork, we use it automatically (bug#10398).
4914 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4916 * window.c (save_window_save): Obey window-point-insertion-type.
4918 2012-04-11 Glenn Morris <rgm@gnu.org>
4920 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
4922 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4924 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
4926 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
4928 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
4929 (force_quit_count): New var.
4930 (handle_interrupt): Use it.
4932 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
4934 * w32.c (w32_delayed_load): Record the full path of the library
4935 being loaded (bug#10424).
4937 2012-04-09 Glenn Morris <rgm@gnu.org>
4939 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4940 not just in the obarray, before snarfing them. (Bug#11036)
4942 * Makefile.in ($(leimdir)/leim-list.el):
4943 Pass EMACS rather than BUILT_EMACS.
4945 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4947 * process.c (make_process):
4948 * process.h: Add integer `gnutls_handshakes_tried' member to
4951 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4952 Add convenience `GNUTLS_LOG2i' macro.
4954 * gnutls.c (gnutls_log_function2i): Convenience log function.
4955 (emacs_gnutls_read): Use new log functions,
4956 `gnutls_handshakes_tried' process member, and
4957 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4958 attempts per process (connection).
4960 2012-04-09 Chong Yidong <cyd@gnu.org>
4962 * eval.c (Fuser_variable_p, user_variable_p_eh)
4963 (lisp_indirect_variable): Functions deleted.
4964 (Fdefvar): Caller changed.
4966 * callint.c (Finteractive, Fcall_interactively):
4967 * minibuf.c (Fread_variable): Callers changed.
4969 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4971 * xdisp.c (set_cursor_from_row): If the display string appears in
4972 the buffer at position that is closer to point than the position
4973 after the display string, display the cursor on the first glyph of
4974 the display string. Fixes cursor display when a 'display' text
4975 property immediately follows invisible text. (Bug#11094)
4977 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4979 composite.c: use 'double' consistently
4980 * composite.c (get_composition_id): Use 'double' consistently
4981 instead of converting 'float' to 'double' and vice versa; this is
4982 easier to understand and avoids a GCC warning.
4984 2012-04-09 Glenn Morris <rgm@gnu.org>
4986 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4987 preparation for dumping it with emacs. (Bug#4789)
4988 (leimdir): New variable.
4989 ($(leimdir)/leim-list.el): New rule.
4990 (emacs$(EXEEXT)): Depend on leim-list.el.

4996 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
4998 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5001 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5003 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5004 Remove unused local variable.
5006 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5008 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5009 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5010 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5011 objects, as mark_maybe_pointer will catch them otherwise.
5012 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5013 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5015 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5017 Fix typo that broke non-Windows builds.
5018 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5020 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5022 Support building on MS-Windows with libxml2.
5024 * makefile.w32-in (OBJ2): Add xml.$(O).
5025 (GLOBAL_SOURCES): Add xml.c.
5026 ($(BLD)/xml.$(O)): New dependency list.
5028 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5029 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5030 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5031 [!WINDOWSNT]: New macros.
5032 (init_libxml2_functions, libxml2_loaded_p): New functions.
5033 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5034 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5035 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5036 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5038 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5039 Call init_libxml2_functions before calling libxml2 functions.
5040 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5042 * emacs.c: Don't include libxml/parser.h.
5043 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5044 xmlCleanupParser directly.
5046 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5048 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5050 * indent.c (Fvertical_motion): If there is a display string at
5051 point, use it.vpos to compute how many lines to backtrack after
5052 move_it_to point. (Bug#11133)
5054 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5056 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5057 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5058 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5059 macros related to unification of CJK characters. For the details,
5060 see the discussion following the message here:
5061 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5063 2012-04-04 Chong Yidong <cyd@gnu.org>
5065 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5067 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5069 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5070 instead of alloca. (Bug#11138)
5072 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5074 * w32menu.c (is_simple_dialog): Properly check lisp types.
5077 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5079 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5080 position we get to after a call to move_it_to fails the
5081 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5082 only if we wind up in a string from display property. (Bug#11063)
5084 * window.c (Fdelete_other_windows_internal): Invalidate the row
5085 and column information about mouse highlight, so that redisplay
5086 restores it after reallocating the glyph matrices. (Bug#7464)
5088 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5089 string comes from a `display' text property, use the buffer
5090 position of that property as if we actually saw that position in
5092 (move_it_by_lines): Remove the assertion that
5093 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5094 violated when there's a before-string at the beginning of a line.
5097 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5099 * xdisp.c (append_space_for_newline): If the default face was
5100 remapped, use the remapped face for the appended newline.
5101 (extend_face_to_end_of_line): Use the remapped default face for
5102 extending the face to the end of the line.
5103 (display_line): Call extend_face_to_end_of_line when the default
5104 face was remapped. (Bug#11068)
5106 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5108 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5110 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5112 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5114 2012-03-27 Glenn Morris <rgm@gnu.org>
5116 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5119 2012-03-26 Kenichi Handa <handa@m17n.org>
5121 * dispextern.h (struct glyph): Fix previous change. Change the
5122 bit length of glyphless.ch to 25 (Bug#11082).
5124 2012-03-26 Chong Yidong <cyd@gnu.org>
5126 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5127 (command_loop_1): Use it; inhibit selection update for
5128 handle-select-window too (Bug#8996).
5130 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5132 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5134 2012-03-25 Kenichi Handa <handa@m17n.org>
5136 * dispextern.h (struct glyph): Change the bit length of
5137 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5139 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5141 * s/ms-w32.h (tzname): Include time.h before redirecting to
5142 _tzname. Fixes the MSVC build. (Bug#9960)
5144 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5146 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5149 * xterm.c (XTread_socket): Only modify handling_signal if
5150 !SYNC_INPUT. (Bug#11080)
5152 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5154 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5155 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5156 when fetching a multibyte character consumes more bytes than
5157 CHAR_BYTES returns, due to unification of CJK characters in
5158 string_char. (Bug#11073)
5160 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5162 * process.c (wait_reading_process_output): Handle pty disconnect
5163 by refraining from sending oneself a SIGCHLD (bug#10933).
5165 2012-03-22 Chong Yidong <cyd@gnu.org>
5167 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5169 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5170 Mark string as coming from a prefix property.
5171 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5172 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5174 2012-03-21 Chong Yidong <cyd@gnu.org>
5176 * xfaces.c (Vface_remapping_alist): Doc fix.
5178 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5180 * w32proc.c (Fw32_set_console_codepage)
5181 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5184 2012-03-20 Chong Yidong <cyd@gnu.org>
5186 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5187 to reflect default non-nil value of redisplay-dont-pause.
5189 2012-03-19 Kenichi Handa <handa@m17n.org>
5191 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5192 it fit in a valid range (Bug#11003).
5194 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5196 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5197 that is not from display property, accept the row as a "cursor
5198 row" if one of the string's character has a non-nil `cursor'
5199 property. Fixes cursor positioning when there are newlines in
5200 overlay strings, e.g. in icomplete.el. (Bug#11035)
5202 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5204 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5206 2012-03-12 Chong Yidong <cyd@gnu.org>
5208 * eval.c (inhibit_lisp_code): Rename from
5209 inhibit_window_configuration_change_hook; move from window.c.
5211 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5212 * window.c (run_window_configuration_change_hook)
5213 (syms_of_window): Callers changed.
5215 2012-03-11 Chong Yidong <cyd@gnu.org>
5217 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5219 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5221 2012-03-10 Chong Yidong <cyd@gnu.org>
5223 * frame.c (other_visible_frames): Don't assume the selected frame
5224 is visible (Bug#10955).
5226 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5228 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5230 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5232 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5233 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5236 2012-03-03 Glenn Morris <rgm@gnu.org>
5238 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5240 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5242 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5243 position past the first glyph_row that ends at ZV. (Bug#10902)
5244 (redisplay_window, next_element_from_string): Fix typos in
5246 (redisplay_window): Pass to move_it_vertically the margin in
5247 pixels, not in screen lines.
5249 2012-03-02 Glenn Morris <rgm@gnu.org>
5251 * buffer.c (buffer-list-update-hook): Doc fix.
5253 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5255 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5256 push_it before setting up the iterator for the first overlay
5257 string, even if we have an empty string loaded.
5258 (next_overlay_string): If there's an empty string on the iterator
5259 stack, pop the stack. (Bug#10903)
5261 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5263 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5264 Suggested by Stefan Monnier in
5265 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5266 * alloc.c (widen_to_Lisp_Object): New static function.
5267 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5268 and widening them to Lisp_Objects. This would work even if
5269 USE_LSB_TAG is defined and wide integers are used, which might
5270 happen in a future version of Emacs.
5272 2012-02-25 Chong Yidong <cyd@gnu.org>
5274 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5277 * xselect.c (Fx_selection_exists_p): Doc fix.
5278 (x_clipboard_manager_save_all): Print an informative message
5279 before saving to clipboard manager.
5281 2012-02-24 Chong Yidong <cyd@gnu.org>
5283 * keyboard.c (process_special_events): Handle all X selection
5284 requests in kbd_buffer, not just the next one (Bug#8869).
5286 2012-02-23 Chong Yidong <cyd@gnu.org>
5288 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5289 call when setting menu-bar-lines and tool-bar-lines parameters.
5290 (unwind_create_frame_1): New helper function.
5292 * window.c (inhibit_window_configuration_change_hook): New var.
5293 (run_window_configuration_change_hook): Obey it.
5294 (syms_of_window): Initialize it.
5296 2012-02-22 Chong Yidong <cyd@gnu.org>
5298 * xterm.c (x_draw_image_relief): Add missing type check for
5299 Vtool_bar_button_margin (Bug#10743).
5301 2012-02-21 Chong Yidong <cyd@gnu.org>
5303 * fileio.c (Vfile_name_handler_alist): Doc fix.
5305 * buffer.c (Fget_file_buffer): Protect against invalid file
5306 handler return value.
5308 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5310 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5311 when computing $valmask.
5313 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5314 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5315 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5316 It's useless in that case, and it can cause problems on hosts
5317 that allocate halves of EMACS_INT values separately.
5318 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5319 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5320 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5321 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5322 it avoids undefined behavior on hosts where shifting right by more
5323 than the word width has undefined behavior.
5325 2012-02-19 Chong Yidong <cyd@gnu.org>
5327 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5328 (Funhandled_file_name_directory, Ffile_name_as_directory)
5329 (Fdirectory_file_name, Fexpand_file_name)
5330 (Fsubstitute_in_file_name): Protect against invalid file handler
5331 return values (Bug#10845).
5333 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5335 * .gdbinit (pitx): Fix incorrect references to fields of the
5338 2012-02-17 Chong Yidong <cyd@gnu.org>
5340 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5342 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>

5928 * fileio.c (Finsert_file_contents): Move after-change-function call
5929 to before the "handled:" label, since all "goto handled" appear in

6111 to 4 (xorl, subq, cmpq, setbe).
6112 * alloc.c (pure): Always extern now, since that's the
6113 VIRT_ADDR_VARIES behavior.
6114 (PURE_POINTER_P): Use a single comparison, not two, for
6115 consistency with the new puresize.h.
6116 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6125 behave as if the cursor position were at the window margin.
6127 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6128 and the cursor position is out of bounds, behave as if the cursor
6129 position were at the window margin. (Bug#10075)

6155 compute_line_metrics.
6156 (compute_line_metrics): Call row_hash, instead of computing the
6159 * dispnew.c (verify_row_hash): Call row_hash for computing the
6160 hash code of a row, instead of duplicating code from xdisp.c.
6162 * dispextern.h (row_hash): Add prototype.
6164 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6166 * frame.c (delete_frame): Don't delete the terminal when the last

6198 * image.c (imagemagick_load_image): Fix typo.
6200 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6202 * xdisp.c (display_line): Move the call to
6203 highlight_trailing_whitespace before the call to

6270 The trivial performance wins aren't worth the portability hassles; see
6271 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6273 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6339 * xmenu.c (cleanup_widget_value_tree): New function.
6340 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
6341 calling free_menubar_widget_value_tree directly (Bug#9830).
6343 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
6345 Fix some portability problems with 'inline'.
6346 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6347 (window_box_width, window_box_left, window_box_left_offset)
6348 (window_box_right, window_box_right_offset): Declare extern.
6349 Otherwise, these inline functions do not conform to C99 and
6350 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6351 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6352 * intervals.c (adjust_intervals_for_insertion)
6353 (adjust_intervals_for_deletion): Now extern, because otherwise the
6354 extern inline functions 'offset_intervals' couldn't refer to it.
6355 (static_offset_intervals): Remove.
6356 (offset_intervals): Rewrite using the old contents of
6357 static_offset_intervals. The old version didn't conform to C99
6358 because an extern inline function contained a reference to an
6359 identifier with static linkage.
6361 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6363 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6381 (Fwindow_vscroll): Doc fix.
6382 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6383 argument, since it makes no sense to pass a live window and for
6384 consistency with window-child.

6415 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6416 Move terminal->reference_count++ just before making the frame official

6495 Rename cover_string to disp_string.
6497 2011-11-01 Martin Rudalics <rudalics@gmx.at>

6530 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6531 so that this new function doesn't get optimized away by a
6532 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6534 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6536 * frame.h (MOUSE_HL_INFO): Remove excess parens.

6557 Not clear what it was for, and it causes various bugs. (Bug#9839)
6559 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6561 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

6563 condition to clear the mouse face.
6565 2011-10-28 Chong Yidong <cyd@gnu.org>

6592 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6594 (w32font_open_internal, compute_metrics):
6595 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6596 instead of calling the "wide" APIs directly.
6598 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

6614 non-NULL, regardless of GNUTLS_INITSTAGE.
6615 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6616 an error. Set process slots as soon as we allocate them.

6662 current character, check also for next_en_type being WEAK_EN.
6663 (bidi_resolve_weak): Don't enter the expensive loop if the current
6664 position is before next_en_pos. Record the bidi type of the first
6665 non-ET, non-BN character we find, in addition to its position.
6666 (bidi_level_of_next_char): Invalidate next_en_type when
6667 next_en_pos is over-stepped.
6669 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6671 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6672 * editfns.c: Rewrite current-time-zone so that it invokes
6673 the equivalent of (format-time-string "%Z") to get the time zone name.
6674 This fixes a bug when the time zone name contains characters that
6675 need converting from the system time locale to Emacs internal format.
6676 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6677 that patch fixed format-time-string to do the conversion, but
6678 I forgot to fix current-time-zone.
6679 (format_time_string): New function, containing most of
6680 what Fformat_time_string used to contain.
6681 (Fformat_time_string): Rewrite in terms of format_time_string.
6682 This doesn't change this function's behavior.
6683 (current-time-zone): Rewrite to use format_time_string.
6684 This fixes the bug reported by Michael Schierl in
6685 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6686 Jason Rumney's 2007-06-07 change worked around this bug, but
6688 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6690 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6692 * xdisp.c (start_display): If the character at POS is displayed
6693 via a display vector, reset IT->current.dpvec_index to zero.
6694 (try_window_reusing_current_matrix): If a line ends in a display
6695 vector or the next line starts in a display vector, continue
6696 redrawing the window even though the character position of
6697 start_row was reached.
6700 2011-10-18 Chong Yidong <cyd@gnu.org>
6702 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6703 with nobreak-char-display too.
6705 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6707 Fix part 3 of bug#9771.
6708 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6709 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6710 non-neutral characters if the current character is a paragraph
6711 separator (a.k.a. Newline). This avoids running the same
6712 expensive loop twice, once when we consume the preceding newline
6713 and the other time when the line actually needs to be displayed.
6714 Avoid the loop when we see neutrals on the base embedding level
6715 following a character whose directionality is the same as the
6716 paragraph's. This avoids running the expensive loop when a line
6717 ends in a long sequence of neutrals, like control characters.
6718 Add assertion against STRONG_AL type. Slightly rearrange code
6719 that determines the type of a neutral given the first non-neutral
6721 (bidi_level_of_next_char): Set next_en_pos to zero when
6722 invalidating its info.
6724 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6726 * xdisp.c (push_display_prop): Determine whether to record string
6727 or buffer position by IT->string, not by IT->method. Allow
6728 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6729 (move_it_vertically_backward): Don't look for character position
6730 immediately after the newline when in a continuation line.
6733 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6735 * window.c (coordinates_in_window): Rewrite and delabelize
6736 vertical border check. (Bug#5357) (Bug#9618)
6738 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6740 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6741 errors in XSetWindowBorder (bug#9310).

6745 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6746 avoid crash when xmalloc overrun checking is enabled.
6748 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6750 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6751 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6752 cursor motion with <left> and <right> arrow keys.
6754 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6755 some callers set that themselves.
6757 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6759 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6760 display string and the previous row comes from the same string and
6761 is empty. (Bug#9739) (Bug#9738)
6763 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6765 * doc.c (get_doc_string): Encode file name (bug#9735).
6767 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6769 * bidi.c (bidi_level_of_next_char):
6770 * xdisp.c (get_visually_first_element): Remove old incorrect
6771 comments regarding the Unicode Line Separator character.
6773 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

6783 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6784 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6786 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6787 Some packages use them to denote characters with modifiers.
6789 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6791 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6792 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6793 matching a pp-number. Rename parameter var to var1.
6795 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6797 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6799 2011-10-08 Glenn Morris <rgm@gnu.org>
6801 * callint.c (Fcall_interactively): Give a more explicit error for the
6802 'c' case with a non-character input. (Bug#8479)
6804 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6806 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6808 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6809 lines that are hscrolled on the left.
6811 * dispnew.c (buffer_posn_from_coords): Account for a possible
6812 presence of header-line. (Bug#4426)
6814 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6816 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6817 Don't advertise functionality which we discourage or doesn't work.
6819 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6821 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6822 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6823 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6824 this makes Emacs dump core during garbage collection on rare
6825 occasions. sizeof is obviously inferior to offsetof here, so
6826 stick with offsetof.
6827 (GC_POINTER_ALIGNMENT): New macro.
6828 (mark_memory): Omit 3rd (offset) arg; caller changed.
6829 Don't assume EMACS_INT alignment is the same as pointer alignment.
6831 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6833 * keyboard.c (read_key_sequence_remapped): New var.
6834 (read_key_sequence): Compute remapping in the right buffer.
6835 (command_loop_1): Use read_key_sequence's remapping directly.
6837 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6839 * dired.c (file_name_completion): Don't expand file name.
6840 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6841 before checking file name handler.
6843 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6844 they've been requested explicitly (bug#9591).
6846 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6848 * keymap.c (Fsingle_key_description): Use make_specified_string
6849 instead of build_string to build string from push_key_description.
6852 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6854 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6855 This fixes a Y2038 bug on 64-bit hosts.
6856 * buffer.c (reset_buffer):
6857 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6858 (Fclear_buffer_auto_save_failure):
6859 Use 0, not -1, to represent an unset failure time, since time_t
6860 might not be signed.
6862 Remove dependency on glibc malloc internals.
6863 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6864 Move back here from lisp.h, but with their new implementations.
6865 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6866 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6867 * charset.c (charset_table_init): New static var.
6868 (syms_of_charset): Use it instead of xmalloc. This removes a
6869 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6870 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6871 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6872 Move back to alloc.c.
6873 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6874 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6876 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6878 * nsterm.m (windowDidResize): Call x_set_window_size only when
6879 ns_in_resize is true. Otherwise set pixelwidth/height and
6880 call change_frame_size (Bug#9628).
6882 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6884 Port --enable-checking=all to Fedora 14 x86-64.
6885 * charset.c (syms_of_charset): Also account for glibc malloc's
6886 internal overhead when calculating the initial malloc maximum.
6888 Port --enable-checking=all to Fedora 14 x86.
6889 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6891 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6892 (overrun_check_realloc, overrun_check_free):
6893 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6894 That way, xmalloc returns a properly-aligned pointer even if
6895 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6896 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6897 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6898 into account when calculating the initial malloc maximum.
6899 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6900 Move here from alloc.c, so that charset.c can use it too.
6901 Properly align; the old code wasn't right for common 32-bit hosts
6902 when configured with --enable-checking=all.
6903 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6904 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6906 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6908 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6911 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6913 * xdisp.c (compute_display_string_end): If there's no display
6914 string at CHARPOS, return -1.
6916 * bidi.c (bidi_fetch_char): When compute_display_string_end
6917 returns a negative value, treat the character as a normal
6918 character not covered by a display string. (Bug#9624)
6920 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6922 * lread.c (Fread_from_string): Fix typo in docstring.
6924 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6926 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6927 newline, reseat the iterator instead of bidi-iterating there one
6928 character at a time. (Bug#9610)
6929 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6930 TO_CHARPOS if the bidi iterator is at base embedding level.
6932 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6934 * lread.c (readevalloop): Use correct code for NBSP.
6935 (read1): Likewise. (Bug#9608)
6937 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6939 * dbusbind.c (Fdbus_register_signal): When service is not
6940 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6942 2011-09-25 Glenn Morris <rgm@gnu.org>
6944 * buffer.c (truncate-lines): Doc fix.
6946 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6948 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6949 (Fset_window_next_buffers): Doc fix.
6951 2011-09-24 Glenn Morris <rgm@gnu.org>
6953 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6955 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6957 Fix minor problems found by static checking.
6958 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6959 * indent.c (Fvertical_motion): Fix == vs = typo.
6961 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6963 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6964 Default value is now t. Doc fix.
6966 * indent.c (Fvertical_motion): Compute and apply the overshoot
6967 logic when moving up, not only when moving down. Fix the
6968 confusing name and values of the it_overshoot_expected variable;
6969 logic changes accordingly. (Bug#9254) (Bug#9549)
6971 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6972 CHARPOS is covered by a display string which includes newlines.
6973 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6974 is covered by a display string with embedded newlines.
6976 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6978 * dbusbind.c (Fdbus_register_signal): Add match rule to
6979 Vdbus_registered_objects_table. (Bug#9581)
6980 (Fdbus_register_method, Vdbus_registered_objects_table):
6983 2011-09-24 Jim Meyering <meyering@redhat.com>
6985 do not ignore write error for any output size
6986 The previous change was incomplete.
6987 While it makes emacs --batch detect the vast majority of stdout
6988 write failures, errors were still ignored whenever the output size is
6989 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6990 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6991 && echo FAIL: ignored write error
6992 FAIL: ignored write error
6993 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6994 && echo FAIL: ignored write error
6995 FAIL: ignored write error
6996 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6998 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7000 * emacs.c (Fkill_emacs): In noninteractive mode exit
7001 non-successfully if a write error occurred on stdout. (Bug#9574)
7003 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7005 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7008 * dispextern.h (struct it): Update the comment documenting what
7011 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7013 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7014 a display string, extend search for cursor position to end of row.
7015 (find_row_edges): If the row ends in a newline from a display
7016 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7017 Handle the case of a display string with multiple newlines.
7018 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7019 non-empty line. Fixes confusing cursor motion with arrow keys at
7020 the beginning of a line that starts with whitespace.
7022 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7024 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7027 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7029 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7032 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7034 * xdisp.c (display_line): Record maximum and minimum buffer
7035 positions even if no glyphs were produced (e.g., by a zero-width
7036 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7037 buffer positions that will be removed from the glyph row because
7039 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7040 column is beyond frame width: don't subtract 1 "pixel" when
7041 computing width of the stretch.
7042 (reseat_at_next_visible_line_start): Undo the change made on
7043 2011-09-17 that saved paragraph information and restored it after
7044 the call to `reseat'. (Bug#9545)
7046 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7048 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7049 and turn window cursor on if cleared (Bug#9415).
7051 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7053 * search.c (boyer_moore): Take unibyte characters from pattern
7054 literally. (Bug#9458)
7056 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7058 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7060 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7062 Fix minor problem found by static checking.
7063 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7064 initialized, to pacify gcc -Wuninitialized.
7066 * fileio.c: Report proper errno when syscall falls.
7067 (Finsert_file_contents): Save and restore errno,
7068 so that report_file_error outputs the correct diagnostic.
7069 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7071 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7073 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7075 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7077 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7078 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7080 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7082 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7083 about the current paragraph and restore it after the call to reseat.
7085 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7086 (bidi_find_paragraph_start): Search back for paragraph beginning
7087 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7088 (bidi_move_to_visually_next): Only trigger paragraph-related
7089 computations when the last character is a newline or at EOB, not
7090 just any NEUTRAL_B. (Bug#9470)
7092 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7093 truncated lines if point is covered by a display string. (Bug#9524)
7095 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7097 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7098 (cons_to_x_long): New function.
7099 (lisp_data_to_selection_data): Use it. Correct the test for
7100 short-versus-long data; it was negated. Break out of vector
7101 loop, for efficiency, when a long datum is discovered.
7103 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7105 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7107 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7109 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7110 GCC PR/17406) by declaring this function with external scope.
7112 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7114 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7115 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7117 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7119 * editfns.c (Fformat): Correctly handle text properties on "%%".
7121 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7123 * xterm.c (x_draw_composite_glyph_string_foreground):
7124 * w32term.c (x_draw_composite_glyph_string_foreground):
7125 * term.c (encode_terminal_code):
7126 * composite.c (composition_update_it, get_composition_id):
7127 * xdisp.c (get_next_display_element)
7128 (fill_composite_glyph_string): Add comments about special meaning
7129 of TAB characters in a composition.
7131 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7133 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7134 This occurs when processing a multibyte format.
7135 Problem reported by Wolfgang Jenker.
7137 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7139 * xdisp.c (try_cursor_movement): Only check for exact match if
7140 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7142 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7144 Remove unused external symbols.
7145 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7146 * xdisp.c (calc_pixel_width_or_height): Now static.
7147 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7148 * indent.c (check_display_width):
7149 * w32term.c: Fix comment to match code.
7150 * xterm.c, xterm.h (x_catching_errors): Remove.
7152 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7154 * xselect.c: Use signed conversions more consistently (Bug#9498).
7155 (selection_data_to_lisp_data): Assume incoming selection data are
7156 signed integers, not unsigned. This is to be consistent with
7157 outgoing selection data, which was modified to use signed integers
7158 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7159 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7160 expects long, not unsigned long.
7162 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7164 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7165 computation of loop end. Reported by Johan Bockgård
7168 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7170 * frame.c (Fother_visible_frames_p): Function deleted.
7172 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7174 * indent.c (compute_motion): Process display vector front to back
7175 rather than the other way around. (Bug#2496)
7177 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7179 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7181 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7183 * minibuf.c (Fread_from_minibuffer): Doc fix.
7185 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7187 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7188 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7190 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7192 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7193 value for non-existent files.
7195 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7197 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7198 set its "size" to -1. This will set the modtime_size field of
7199 the corresponding buffer to -1, which is what
7200 verify-visited-file-modtime expects for files that do not exist.
7203 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7205 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7207 * lisp.h: ... from here. push_key_description is no longer
7208 defined in keyboard.c, so its declaration should not be in
7209 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7210 logically belongs with push_key_description.
7212 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7214 * buffer.h: Include <sys/types.h> instead of <time.h>.
7215 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7216 Problem reported by Herbert J. Skuhra.
7218 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7220 * xml.c (parse_region): Make the parsing work for
7221 non-comment-starting XML files again (bug#9144).
7223 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7225 * image.c (gif_load): Fix calculation of bottom and right corner.
7228 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7230 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7231 redisplay in small windows.
7233 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7235 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7237 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7239 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7240 Operate on live windows only.
7242 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7244 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7246 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7248 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7249 only under bidi iteration.
7251 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7253 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7255 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7257 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7258 Without this fix, the command to link temacs failed due to an
7259 undefined symbol __builtin_isnan. This is because
7260 /usr/include/iso/math_c99.h #defines isnan(x) to
7261 __builtin_isnan(x), but the bundled gcc, which identifies itself
7262 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7264 * floatfns.c (isnan): #undef, and then #define to a clone of
7266 (Fisnan): Always define, since it's always available now.
7267 (syms_of_floatfns): Always define isnan at the Lisp level.
7269 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7271 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7273 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7275 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7276 The previous code assumed that file offsets (off_t values) fit in
7277 EMACS_INT variables, which is not true on typical 32-bit hosts.
7278 The code messed up by falsely reporting buffer overflow in cases
7279 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7280 when "big" contains more than 2**29 bytes, even though this
7281 inserts just one byte and does not overflow the buffer.
7282 (Finsert_file_contents): Store file offsets as off_t
7283 values, not as EMACS_INT values. Check for overflow when
7284 converting between EMACS_INT and off_t. When checking for
7285 buffer overflow or for overlap, take the offsets into account.
7286 Don't use EMACS_INT for small values where int suffices.
7287 When checking for overlap, fix a typo: ZV was used where
7288 ZV_BYTE was intended.
7289 (Fwrite_region): Don't assume off_t fits into 'long'.
7290 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7292 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7294 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7296 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7298 sprintf-related integer and memory overflow issues (Bug#9412).
7300 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7301 (esprintf, exprintf, evxprintf): New functions.
7302 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7303 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7304 (modify_event_symbol): Do not assume that the length of
7305 name_alist_or_stem is safe to alloca and fits in int.
7306 (Fexecute_extended_command): Likewise for function name and binding.
7307 (Frecursion_depth): Wrap around reliably on integer overflow.
7308 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7309 since some callers pass EMACS_INT values.
7310 (Fsingle_key_description): Don't crash if symbol name contains more
7311 than MAX_ALLOCA bytes.
7312 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7313 (get_minibuffer): Arg is now EMACS_INT, not int.
7314 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7315 (esprintf, exprintf, evxprintf): New decls.
7316 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7318 * dbusbind.c (signature_cat): New function.
7319 (xd_signature, Fdbus_register_signal):
7320 Do not overrun buffer; instead, report string overflow.
7322 * dispnew.c (add_window_display_history): Don't overrun buffer.
7323 Truncate instead; this is OK since it's just a log.
7325 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7326 even if the time zone offset is outlandishly large.
7327 Don't mishandle offset == INT_MIN.
7329 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7330 when creating daemon; the previous buffer-overflow check was incorrect.
7332 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7333 which has the guts of the old verror function.
7335 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7336 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7338 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7339 (font_unparse_xlfd): Don't blindly alloca long strings.
7340 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7341 fits in int, when using sprintf. Use single snprintf to count
7342 length of string rather than counting it via multiple sprintfs;
7343 that's simpler and more reliable.
7344 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7345 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7346 sprintf, in case result does not fit in int.
7348 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7349 (fontset_from_font): Print it.
7351 * frame.c (tty_frame_count): Now printmax_t, not int.
7352 (make_terminal_frame, set_term_frame_name): Print it.
7353 (x_report_frame_params): In X, window IDs are unsigned long,
7354 not signed long, so print them as unsigned.
7355 (validate_x_resource_name): Check for implausibly long names,
7356 and don't assume name length fits in 'int'.
7357 (x_get_resource_string): Don't blindly alloca invocation name;
7358 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7361 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7362 (xg_check_special_colors, xg_set_geometry):
7363 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7365 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7366 Use esprintf, not sprintf, in case result does not fit in int.
7368 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7369 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7370 it as a large positive number.
7371 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7372 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7374 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7375 in case result does not fit in int.
7377 * print.c (float_to_string): Detect width overflow more reliably.
7378 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7379 buffer overrun. Don't assume list length fits in 'int'. Treat
7380 print length of 0 as 0, not as infinity; to be consistent with other
7381 uses of print length in this function. Don't overflow print length
7382 index. Don't assume hash table size fits in 'long', or that
7383 vectorlike size fits in 'unsigned long'.
7385 * process.c (make_process): Use printmax_t, not int, to format
7386 process-name gensyms.
7388 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7390 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7391 to avoid potential buffer overrun.
7393 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7394 if X resource line is longer than 512 bytes.
7396 * xfns.c (x_window): Make sprintf buffer a bit bigger
7397 to avoid potential buffer overrun.
7399 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7401 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7403 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7405 Integer overflow fixes for scrolling, etc.
7406 Without these, Emacs silently mishandles large integers sometimes.
7407 For example, "C-u 4294967297 M-x recenter" was treated as if
7408 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7410 * xdisp.c (try_window_id): Check Emacs fixnum range before
7411 converting to 'int'.
7413 * window.c (window_scroll_line_based, Frecenter):
7414 Check that an Emacs fixnum is in range before assigning it to 'int'.
7415 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7416 values converted from Emacs fixnums.
7417 (Frecenter): Don't wrap around a line count if it is out of 'int'
7418 range; instead, treat it as an extreme value.
7419 (Fset_window_configuration, compare_window_configurations):
7420 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7422 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7423 that can exceed INT_MAX. Check that EMACS_INT value is in range
7424 before assigning it to the (possibly-narrower) index.
7425 (match_limit): Don't assume that a fixnum can fit in 'int'.
7427 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7430 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7431 (Fvertical_motion): Don't wrap around LINES values that don't fit
7432 in 'int'. Instead, treat them as extreme values. This is good
7433 enough for windows, which can't have more than INT_MAX lines anyway.
7435 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7437 * Require libxml/parser.h to avoid compilation warning.
7439 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7441 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7442 since this reportedly can destroy thread storage.
7444 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7446 * syntax.c (find_defun_start): Update all cache variables if
7447 exiting early (Bug#9401).
7449 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7451 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7453 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7454 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7455 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7457 * term.c (tty_append_glyph): New function.
7458 (produce_stretch_glyph): Static function and its prototype deleted.
7460 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7463 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7465 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7466 when checking :margin (Bug#9390).
7467 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7468 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7469 so that the name doesn't mislead. All uses changed.
7471 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7473 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7476 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7478 * xdisp.c (move_it_to): Don't bail out early when reaching
7479 position beyond to_charpos, if we are scanning backwards.
7480 (move_it_vertically_backward): When DY == 0, make sure we get to
7481 the first character in the line after the newline.
7483 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7485 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7486 (ccl_driver): Do not generate an out-of-range pointer.
7487 (Fccl_execute_on_string): Remove unnecessary check for
7488 integer overflow, noted by Stefan Monnier in
7489 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7490 Remove a FIXME that didn't need fixing.
7491 Simplify the newly-introduced buffer reallocation code.
7493 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7495 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7497 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7499 Integer and memory overflow issues (Bug#9196).
7501 * doc.c (get_doc_string): Rework so that
7502 get_doc_string_buffer_size is the actual buffer size, rather than
7503 being 1 less than the actual buffer size; this makes xpalloc more
7506 * image.c (x_allocate_bitmap_record, cache_image):
7507 * xselect.c (Fx_register_dnd_atom):
7508 Simplify previous changes by using xpalloc.
7510 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7511 since either will do and ptrdiff_t is convenient with xpalloc.
7513 * charset.c (charset_table_size)
7514 (struct charset_sort_data.priority): Now ptrdiff_t.
7515 (charset_compare): Don't overflow if priorities differ greatly.
7516 (Fsort_charsets): Don't assume list length fits in int.
7517 Check for size-calculation overflow when allocating sort data.
7518 (syms_of_charset): Allocate an initial charset table that is
7519 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7521 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7523 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7524 The actual value is always <= INT_MAX, and leaving it unsigned made
7525 overflow checking harder.
7527 * dispextern.h (struct glyph_matrix.rows_allocated)
7528 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7529 with xpalloc. The values are still always <= INT_MAX.
7531 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7533 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7534 (SAFE_NALLOCA): New macro.
7536 * region-cache.c (struct boundary.pos, find_cache_boundary)
7537 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7538 (set_cache_region, invalidate_region_cache)
7539 (revalidate_region_cache, know_region_cache, region_cache_forward)
7540 (region_cache_backward, pp_cache):
7541 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7542 so that ptrdiff_t * can be passed to xpalloc.
7543 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7544 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7545 (pp_cache): Don't assume cache_len fits in int.
7546 * region-cache.h: Adjust extern decls to match.
7548 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7549 EMACS_INT, since either will do, for xpalloc.
7551 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7552 (xnmalloc, xnrealloc, xpalloc): New functions.
7554 * bidi.c (bidi_shelve_header_size): New constant.
7555 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7556 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7558 * bidi.c (bidi_cache_shrink):
7559 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7561 Don't update size of array until after memory allocation succeeds,
7562 because xmalloc/xrealloc may not return.
7563 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7564 now that we have proper integer overflow checking.
7565 (record_overlay_string, overlay_strings): Catch overflows when
7566 calculating size of overlay_str_buf.
7568 * callproc.c (Fcall_process): Check for size overflow when
7569 calculating size of args2.
7570 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7571 Normally we prefer signed values, but sticking with ptrdiff_t would
7572 require adding more-complicated checks.
7574 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7575 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7576 Redo buffer-overflow calculations to avoid integer overflow.
7577 Add a FIXME comment where memory seems to be over-allocated.
7579 * character.c (Fstring): Check for size-calculation overflow.
7581 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7582 unnecessary integer overflow. Check for size overflow.
7583 (encode_coding_object): Don't update size until xmalloc succeeds.
7585 * composite.c (get_composition_id): Check for overflow in glyph
7586 length calculations.
7588 Integer and memory overflow fixes for display code.
7589 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7590 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7591 (scrolling_window): Check for overflow in size calculations.
7592 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7593 Don't assume glyph table len fits in int.
7594 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7595 (row_table_size): Now ptrdiff_t, not int.
7596 (scrolling_window): Avoid overflow in size calculations.
7597 Don't update size until allocation succeeds.
7598 * fns.c (concat): Check for overflow in size calculations.
7599 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
7600 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7601 (NEXT_ALMOST_PRIME_LIMIT): New constant.
7603 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7604 (get_doc_string): Check for size calculation overflow.
7605 Don't update size until allocation succeeds.
7606 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7607 EMACS_INT, where ptrdiff_t will do.
7608 (Fsubstitute_command_keys): Check for string overflow.

7612 (message_length): Now ptrdiff_t, not int.
7613 (Fmessage_box): Don't update size until allocation succeeds.
7614 Don't assume message length fits in int.
7615 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7617 * emacs.c (main): Do not reallocate argv, since there is a null at
7618 the end that can be overwritten, and this way there's no need to
7619 worry about size-calculation overflow.
7620 (sort_args): Check for size-calculation overflow.
7622 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7624 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7626 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7627 (x_set_scroll_bar_width, x_figure_window_size):
7628 Check for integer overflow.
7629 (x_set_alpha): Do not assume XINT fits in int.
7631 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7632 This is for the members text_lines, text_cols, total_lines, total_cols,
7633 where the system imposes an 'int' limit.
7635 * fringe.c (Fdefine_fringe_bitmap):
7636 Don't update size until alloc works.
7638 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7639 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7641 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7642 Check for size-calculation overflow.
7643 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7644 do, as we prefer signed integers.
7645 (id_to_widget.max_size, id_to_widget.used)
7646 (xg_store_widget_in_map, xg_remove_widget_from_map)
7647 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7648 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7649 Use and return ptrdiff_t, not int.
7650 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7651 * gtkutil.h: Change prototypes to match the above.
7653 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7654 are duplicate now that they've been promoted to lisp.h.
7655 (x_allocate_bitmap_record, x_alloc_image_color)
7656 (make_image_cache, cache_image, xpm_load):
7657 Don't update size until alloc is done.
7658 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7660 Check for size calculation overflow.
7661 (ct_colors_allocated_max): New constant.
7662 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

7667 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7668 Use ptrdiff_t, not int, to count maps.
7669 (read_char_minibuf_menu_prompt): Check for overflow in size
7670 calculations. Don't update size until allocation succeeds.

7682 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7684 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7685 Now ptrdiff_t, not int.
7686 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
7687 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.

7698 (Fset_match_data): Don't assume list lengths fit in 'int'.
7700 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7701 for command line length. Do not attempt to address one before the
7702 beginning of an array, as that's not portable.

7705 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7707 (encode_terminal_code, calculate_costs): Check for size
7708 calculation overflow.

7730 Use ptrdiff_t, not int, for sizes.
7731 (Finternal_make_lisp_face, cache_face):
7732 Check for size calculation overflow.
7733 (cache_face): Treat size calculation overflows as if they were
7734 memory exhaustion (the usual treatment), rather than aborting.
7736 * xfns.c (x_encode_text, x_set_name_internal)
7737 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7738 sizes, since they can exceed INT_MAX in size. Check for size

7745 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7746 as sprintf is limited to int lengths.
7748 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7749 (X_LONG_MIN): New macros.
7750 Use them to make the following changes clearer.
7751 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7752 This change doesn't affect the value now, but it may help remind
7753 future maintainers not to raise the value too much later.
7754 (SELECTION_QUANTUM): Remove, replacing with ...
7755 (selection_quantum): ... new function, which avoids overflow.
7757 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7758 assumption that selection length fits in 'int'.
7759 (x_reply_selection_request, x_handle_selection_request)
7760 (x_get_window_property, receive_incremental_selection)
7761 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7762 (lisp_data_to_selection_data, clean_local_selection_data):
7763 Use ptrdiff_t, not int, to record length of selection.
7764 (x_reply_selection_request, x_get_window_property)
7765 (receive_incremental_selection, x_property_data_to_lisp):
7766 Redo calculations to avoid overflow.
7767 (x_reply_selection_request): When sending hint, ceiling it at
7768 X_LONG_MAX rather than relying on wraparound overflow to send
7770 (x_get_window_property, receive_incremental_selection)
7771 (lisp_data_to_selection_data, x_property_data_to_lisp):
7772 Check for size-calculation overflow.
7773 (x_get_window_property, receive_incremental_selection)

7775 Don't store size until memory allocation succeeds.
7776 (x_get_window_property): Plug memory leak on memory exhaustion.
7777 Don't double-block input; malloc is safe here. Don't assume 2**34
7778 - 4 fits in unsigned long. Add an xassert to check
7779 XGetWindowProperty overflow. Be more careful about overflow
7780 calculations, and distinguish size from memory overflow better.
7781 (receive_incremental_selection): When tracing, don't assume
7782 unsigned int is less than INT_MAX.
7783 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7784 harmful) conversions of unsigned short to int.
7785 (lisp_data_to_selection_data): Don't assume that integers
7786 in the range -65535 through -1 fit in an X unsigned short.
7787 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7788 result parameters unless successful. Rely on cons_to_unsigned
7789 to report problems with elements; the old code wasn't right anyway.
7790 (x_check_property_data): Check for int overflow; we cannot use
7791 a wider type due to X limits.
7792 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7794 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7796 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7797 (x_term_init): Check for size calculation overflow.
7798 (x_color_cells): Don't store size until memory allocation succeeds.
7799 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
7800 Don't assume alloca size is less than MAX_ALLOCA.

7823 * image.c (xpm_get_color_table_h):
7824 * lisp.h (hash_lookup, hash_put):
7825 * minibuf.c (Ftest_completion):
7826 Use ptrdiff_t for hash table indexes, not int (which is too
7827 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7828 32-bit --with-wide-int hosts).
7830 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7831 Add a FIXME comment about memory leaks.
7832 (syms_of_charset): Don't assume xmalloc returns.
7834 Don't assume that stated character widths fit in int.
7835 * character.c (Fchar_width, c_string_width, lisp_string_width):
7836 * character.h (CHAR_WIDTH):
7837 * indent.c (MULTIBYTE_BYTES_WIDTH):
7838 Use sanitize_char_width to avoid undefined and/or bad behavior
7839 with outlandish widths.
7840 * character.h (sanitize_tab_width): Rename from sanitize_width,
7841 now that we have two such functions. All uses changed.
7842 (sanitize_char_width): New inline function.
7844 Don't assume that tab-width fits in int.
7845 * character.h (sanitize_width): New inline function.
7846 (SANE_TAB_WIDTH): New macro.
7847 (ASCII_CHAR_WIDTH): Use it.
7848 * indent.c (sane_tab_width): Remove. All uses replaced by
7849 SANE_TAB_WIDTH (current_buffer).
7850 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
7852 * fileio.c: Integer overflow issues with file modes.
7853 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7855 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

7859 * xterm.c: Don't go over XClientMessageEvent limit.
7860 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7861 (x_send_scroll_bar_event): Likewise. Check that the size does not
7862 exceed limits imposed by XClientMessageEvent, as well as the usual
7863 ptrdiff_t and size_t limits.
7865 * keyboard.c: Overflow, signedness and related fixes.
7866 (make_lispy_movement): Use same integer type in forward decl
7867 that is used in the definition.
7868 (read_key_sequence, keyremap_step):
7869 Change bufsize argument back to int, undoing my 2011-03-30 change.
7870 We prefer signed types, and int is wide enough here.
7871 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7872 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7873 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7874 length, not size_t. Use ptrdiff_t for index, not int.
7875 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7876 possibility of integer overflow.
7878 Overflow, signedness and related fixes for images.
7880 * dispextern.h (struct it.stack[0].u.image.image_id)
7881 (struct_it.image_id, struct image.id, struct image_cache.size)

7887 * nsmenu.m (update_frame_tool_bar):
7888 * xdisp.c (calc_pixel_width_or_height):
7889 * xfns.c (image_cache_refcount):
7890 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7891 on typical 64-bit hosts.
7893 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7894 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7895 Omit unnecessary casts to int.

7897 when the callers expect that.
7898 (image_ascent): Redo ascent calculation to avoid int overflow.
7899 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7900 (lookup_image): Remove unnecessary tests.
7901 (xbm_image_p): Locals are now of int, not EMACS_INT,
7902 since parse_image_check makes sure they fit into int.
7903 (png_load, gif_load, svg_load_image):
7904 Prefer int to unsigned where either will do.
7905 (tiff_handler): New function, combining the cores of the
7906 old tiff_error_handler and tiff_warning_handler.
7907 This function is rewritten to use vsnprintf and thereby avoid
7908 stack buffer overflows. It uses only the features of vsnprintf
7909 that are common to both POSIX and native Microsoft.
7910 (tiff_error_handler, tiff_warning_handler): Use it.
7911 (tiff_load, gif_load, imagemagick_load_image):
7912 Don't assume :index value fits in 'int'.
7913 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7914 (imagemagick_load_image): Check that crop parameters fit into
7915 the integer types that MagickCropImage accepts. Don't assume
7916 Vimagemagick_render_type has a nonnegative value. Don't assume
7917 size_t fits in 'long'.
7918 (gs_load): Use printmax_t to print the widest integers possible.
7919 Check for integer overflow when computing image height and width.
7921 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7923 * xdisp.c (redisplay_window): Don't force window start if point
7924 will be invisible in the resulting window. (Bug#9324)
7926 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7928 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7929 the display spec is of the form `(space ...)'.
7930 (handle_display_spec): Return the value returned by
7931 handle_single_display_spec, not just 1 or zero.
7932 (handle_single_display_spec): If the display spec is of the form
7933 `(space ...)', and specifies display in the text area, return 2
7935 (try_cursor_movement): Check for the need to scroll more
7936 accurately, and prefer exact match for point under bidi.
7937 Don't advance `row' beyond the last row of the window.
7939 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7940 into disp_prop; all users changed.
7942 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7943 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7944 for the text covered by the display property.
7946 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7948 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7954 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7955 buffers, return left-to-right.
7956 (set_cursor_from_row): Consider candidate row a win if its glyph
7957 represents a newline and point is on that newline. Fixes cursor
7958 positioning on the newline at EOL of R2L text within L2R
7959 paragraph, and vice versa.
7960 (try_cursor_movement): Check continued rows, in addition to
7961 continuation rows. Fixes unwarranted scroll when point enters a
7962 continued line of R2L text within an L2R paragraph, or vice versa.
7963 (cursor_row_p): Consider the case of point being equal to
7964 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7965 from the end of a short line to the beginning of a continued line
7966 of R2L text within L2R paragraph.
7967 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7968 composed characters.
7970 * bidi.c (bidi_check_type): Use xassert.
7971 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7974 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7976 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
7979 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7981 * nsfont.m (ns_otf_to_script): Fix typo.
7983 2011-08-22 Kenichi Handa <handa@m17n.org>
7985 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7986 extra slot even if the purpose is char-code-property-table.
7988 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7990 * xdisp.c (redisplay_window): When computing centering_position,
7991 account for the height of the header line. (Bug#8874)
7993 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7994 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7995 candidate is selected by the mouse, and that candidate has a
7996 composed character under the mouse.
7998 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7999 coordinates reported by pos-visible-in-window-p for a composed
8000 character in column zero.
8002 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8004 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8006 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8008 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8009 consider it a hit if to_charpos is anywhere in the range of the
8010 composed buffer positions.
8012 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8014 * image.c (gif_load): Don't assume that each subimage has the same
8015 dimensions as the base image. Handle disposal method that is
8016 "undefined" by the gif spec (Bug#9335).
8018 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8020 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8021 (Fcondition_case): Document `debug' symbol in error handler.
8023 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8025 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8026 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8027 from an Org mode buffer to a Speedbar frame.
8029 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8030 a composition, take its buffer position from IT->cmp_it.charpos.
8031 Fixes cursor positioning at the beginning of a line that begins
8032 with a composed character.
8034 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8036 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8037 character bidirectional type, use STRONG_L instead. Fixes crashes
8038 in a buffer produced by `describe-categories'.
8040 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8041 members before the level stack, so they would be saved and
8042 restored when copying iterator state. Fixes incorrect reordering
8043 around TABs covered by display properties.
8045 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8047 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8049 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8051 * eval.c (internal_condition_case, internal_condition_case_1)
8052 (internal_condition_case_2, internal_condition_case_n):
8053 Remove unnecessary aborts (Bug#9081).
8055 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8057 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8058 has no `load' handler, try opening the file locally. (Bug#9311)
8060 2011-08-16 Ken Brown <kbrown@cornell.edu>
8062 * gmalloc.c: Expand comment.
8064 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8066 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8067 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8069 2011-08-16 Ken Brown <kbrown@cornell.edu>
8071 Fix memory allocation problems in Cygwin build (Bug#9273).
8073 * unexcw.c ( __malloc_initialized): Declare external variable.
8074 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8076 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8078 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8080 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8082 [CYGWIN] (special_realloc): New function.
8083 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8084 requests to realloc storage in the static heap.
8086 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>

8095 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8097 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8099 * chartab.c: Improve commentary for the uniprop_table API.
8101 * bidi.c (bidi_paragraph_init): Support zero value of
8102 bidi_ignore_explicit_marks_for_paragraph_level.
8103 (bidi_initialize): Use uniprop_table instead of including
8104 biditype.h and bidimirror.h.
8106 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8107 coordinates of the iterator when restoring from ppos_it.
8110 2011-08-14 Kenichi Handa <handa@m17n.org>
8112 * process.c (create_process): Call setup_process_coding_systems
8113 after the pid of the process is set to -1 (Bug#8162).
8115 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8117 * xdisp.c (move_it_in_display_line_to): Don't invoke
8118 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8119 ppos_it. Fixes vertical cursor motion when line beginning is
8120 covered by an image. (Bug#9296)
8122 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8124 * nsterm.h (ns_run_ascript): Declare.
8125 (NSAPP_DATA2_RUNASSCRIPT): Define.
8127 * nsfns.m (as_script, as_result, as_status): New static variables.
8128 (ns_run_ascript): New function.
8129 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8130 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8131 the event loop. Get status from as_status (Bug#7276).
8133 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8134 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8135 the event loop (Bug#7276).
8137 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8139 * gnutls.c (QCgnutls_bootprop_priority)
8140 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8141 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8142 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

8144 (QCgnutls_bootprop_verify_hostname_error)
8145 (QCgnutls_bootprop_callbacks_verify): Rename from
8146 Qgnutls_bootprop_..., all uses changed.
8148 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8151 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8153 * xfaces.c (Qframe_set_background_mode): Now static.
8154 * dispextern.h (Qframe_set_background_mode): Remove decl.
8156 * process.c (Fnetwork_interface_info): Declare local only if needed.
8158 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8160 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8161 (Fnetwork_interface_list): Allocate in increments of bytes instead
8162 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8163 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8165 (struct ifflag_def): notrailers is smart on OSX.
8166 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8167 Get hardware address with getifaddrs if available.
8169 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8171 * xdisp.c (iterate_out_of_display_property): xassert that
8172 IT->position is set to within IT->object's boundaries. Break from
8173 the loop as soon as EOB is reached; avoids infloops in redisplay
8174 when IT->position is set up wrongly due to some bug.
8175 Set IT->current to match the bidi iterator unconditionally.
8176 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8177 entry. Force push_it to save on the stack the current
8178 buffer/string position, to be restored by pop_it. Fix flags in
8179 the iterator structure wrt the object coming from a display
8180 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8181 properties. (Bug#9284)
8183 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8185 * fontset.c (fontset_get_font_group): Add proper type checks.
8188 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8190 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8191 and LC_VERSION_MIN_MACOSX.
8192 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8193 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8195 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8197 * xdisp.c (forward_to_next_line_start): Allow to use the
8198 no-display-properties-and-no-overlays under bidi display.
8199 Set disp_pos in the bidi iterator to avoid searches for display
8200 properties and overlays.
8202 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8204 * editfns.c (Fset_time_zone_rule): Document relationship with the
8207 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8208 the font entity extracted from the cache (Bug#8109).
8210 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8212 * composite.c (autocmp_chars): Don't reset point. That is done by
8213 restore_point_unwind (Bug#5984).
8215 2011-08-07 Juri Linkov <juri@jurta.org>
8217 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8218 to show the arg `TIME' instead of `TIMEVAL'.
8220 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8222 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8223 display property strides EOL and includes a newline, as in
8224 longlines-mode. (Bug#9254)
8225 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8226 word-wrap under bidirectional display. (Bug#9224)
8228 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8229 is non-zero, even if the data buffer is NULL. Fixes a crash in
8230 vertical-motion with longlines-mode. (Bug#9254)
8232 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8234 * bidi.c <bidi_cache_total_alloc>: Now static.
8235 (bidi_initialize): Initialize bidi_cache_total_alloc.
8237 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8240 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8241 amount allocated this far in `bidi_cache_total_alloc'.
8242 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8243 non-zero, only free the data buffer without restoring the cache
8244 contents. All callers changed.
8246 * dispextern.h (bidi_unshelve_cache): Update prototype.
8248 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8249 (move_it_in_display_line, move_it_to)
8250 (move_it_vertically_backward, move_it_by_lines): Replace the call
8251 to xfree to an equivalent call to bidi_unshelve_cache.
8252 (move_it_in_display_line_to): Fix logic of returning
8253 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8255 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8257 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8258 came from a string character with a `cursor' property. (Bug#9229)
8260 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8262 * Makefile.in (LIB_PTHREAD): New variable.
8263 (LIBES): Add LIB_PTHREAD (Bug#9216).
8265 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8266 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8268 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8270 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8272 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8274 * xterm.c (x_find_topmost_parent): New function.
8275 (x_set_frame_alpha): Find topmost parent window with
8276 x_find_topmost_parent and set the property there also (bug#9181).
8277 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8279 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8281 * callproc.c (Fcall_process): Avoid vfork clobbering
8282 the local vars buffer, coding_systems, current_dir.
8284 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8286 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8288 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8290 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8291 so that it is not optimized away.
8293 * xdisp.c (compute_display_string_pos): Remove unused local.
8295 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8297 Fix slow cursor motion and scrolling in large buffers with
8298 selective display, like Org Mode buffers. (Bug#9218)
8300 * dispextern.h (struct bidi_it): New member disp_prop_p.
8302 * xdisp.c: Remove one-slot cache of display string positions.
8303 (compute_display_string_pos): Accept an additional argument
8304 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8305 for a display string or property. If found, set DISP_PROP_P
8308 * bidi.c (bidi_fetch_char): Accept an additional argument
8309 DISP_PROP_P, and pass it to compute_display_string_pos.
8310 Only handle text covered by a display string if DISP_PROP_P is returned
8311 non-zero. All callers of bidi_fetch_char changed.
8313 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8315 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8317 2010-12-03 Don March <don@ohspite.net>
8319 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8320 last character M-[char] is translated to ESC [char] (bug#7541).
8322 2011-08-02 Kenichi Handa <handa@m17n.org>
8324 * lisp.h (uniprop_table): Extern it.
8326 * chartab.c (uniprop_table): Make it non-static.
8328 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8330 * xdisp.c (forward_to_next_line_start): Accept additional argument
8331 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8333 (reseat_at_next_visible_line_start): Use the bidi iterator state
8334 returned by forward_to_next_line_start to restore the state of
8335 it->bidi_it after backing up to previous newline. (Bug#9212)
8337 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8339 * regex.c (re_comp): Protoize.
8340 (re_exec): Fix return type.
8341 (regexec): Fix type of `ret'. (Bug#9203)
8343 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8345 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8346 This is needed if max-image-size is a floating-point number.
8348 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8350 * print.c (print_object): Print empty symbol as ##.
8352 * lread.c (read1): Read ## as empty symbol.
8354 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8356 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8357 setting frame foreground color (Bug#9175).
8358 (x_set_background_color): Likewise.
8360 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8361 contents (Bug#9176).
8362 (EmacsTooltip -init): Remove bezels and add shadows to
8365 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8366 or scroll bar (Bug#8470).
8368 * nsfont.m (nsfont_open): Remove assignment to voffset and
8369 unnecessary vars hshink, expand, hd, full_height, min_height.
8370 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8372 * nsterm.h (nsfont_info): Remove voffset field.
8374 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8376 Implement strike-through and overline on NextStep (Bug#8863).
8378 * nsfont.m (nsfont_open): Use underline position provided by font,
8379 instead of hard-coded value of 2.
8380 (nsfont_draw): Call ns_draw_text_decoration instead.
8382 * nsterm.h: Add declaration for ns_draw_text_decoration.
8384 * nsterm.m (ns_draw_text_decoration): New function for drawing
8385 underline, overline, and strike-through.
8386 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8387 ns_draw_text_decoration. Change treatment of cursor drawing to
8388 accommodate underlining, etc.
8390 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8392 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8395 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8397 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8398 Without this fix, if a signal arrives just after memory fills up,
8399 'malloc' might be invoked reentrantly.
8401 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8402 In other words, assume that every image size is allowed, on non-X
8403 hosts. This assumption is probably wrong, but it lets Emacs compile.
8405 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8407 * regex.c (re_iswctype): Convert return values to boolean.
8409 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8411 * xdisp.c (compute_display_string_pos): Don't use cached display
8412 string position if the buffer had its restriction changed.
8415 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8417 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8419 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8421 Integer signedness and overflow and related fixes. (Bug#9079)
8423 * bidi.c: Integer size and overflow fixes.
8424 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8425 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8426 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8427 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8428 (bidi_find_other_level_edge):
8429 Use ptrdiff_t instead of EMACS_INT where either will do.
8430 This works better on 32-bit hosts configured --with-wide-int.
8431 (bidi_cache_ensure_space): Check for size-calculation overflow.
8432 Use % rather than repeated addition, for better worst-case speed.
8433 Don't set bidi_cache_size until after xrealloc returns, because it
8435 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8436 (bidi_cache_ensure_space): Also check that the bidi cache size
8437 does not exceed that of the largest Lisp string or buffer. See Eli
8438 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8440 * alloc.c (__malloc_size_t): Remove.
8441 All uses replaced by size_t. See Andreas Schwab's note
8442 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8444 * image.c: Improve checking for integer overflow.
8445 (check_image_size): Assume that f is nonnull, since
8446 it is always nonnull in practice. This is one less thing to
8447 worry about when checking for integer overflow later.
8448 (x_check_image_size): New function, which checks for integer
8449 overflow issues inside X.
8450 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8451 This removes the need for a memory_full check.
8452 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8453 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8454 (xbm_read_bitmap_data): Change locals back to 'int', since
8455 their values must fit in 'int'.
8456 (xpm_load_image, png_load, tiff_load):
8457 Invoke x_create_x_image_and_pixmap earlier,
8458 to avoid much needless work if the image is too large.
8459 (tiff_load): Treat overly large images as if
8460 x_create_x_image_and_pixmap failed, not as malloc failures.
8461 (gs_load): Use x_check_image_size.
8463 * gtkutil.c: Omit integer casts.
8464 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8465 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8467 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8469 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8470 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8471 would wrongly return t on a 64-bit host.
8473 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8474 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8475 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8476 and therefore cause GCC to emit a bogus diagnostic in some cases.
8478 * image.c: Integer signedness and overflow and related fixes.
8479 This is not an exhaustive set of fixes, but it's time to
8480 record what I've got.
8481 (lookup_pixel_color, check_image_size): Remove redundant decls.
8482 (check_image_size): Don't assume that arbitrary EMACS_INT values
8483 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8484 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8485 (tiff_load, imagemagick_load_image):
8486 Check for overflow in size calculations.
8487 (x_create_x_image_and_pixmap): Remove unnecessary test for
8488 xmalloc returning NULL; that can't happen.
8489 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8490 (xpm_color_bucket): Use better integer hashing function.
8491 (xpm_cache_color): Don't possibly over-allocate memory.
8492 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8493 (gif_memory_source):
8494 Use ptrdiff_t, not int or size_t, to record sizes.
8495 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8496 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8497 either works, as we prefer signed integers.
8498 (tiff_read_from_memory, tiff_write_from_memory):
8499 Return tsize_t, not size_t, since that's what the TIFF API wants.
8500 (tiff_read_from_memory): Don't fail simply because the read would
8501 go past EOF; instead, return a short read.
8502 (tiff_load): Omit no-longer-needed casts.
8503 (Fimagemagick_types): Don't assume size fits into 'int'.
8505 Improve hashing quality when configured --with-wide-int.
8506 * fns.c (hash_string): New function, taken from sxhash_string.
8507 Do not discard information about ASCII character case; this
8508 discarding is no longer needed.
8509 (sxhash-string): Use it. Change sig to match it. Caller changed.
8510 * lisp.h: Declare it.
8511 * lread.c (hash_string): Remove, since we now use fns.c's version.
8512 The fns.c version returns a wider integer if --with-wide-int is
8513 specified, so this should help the quality of the hashing a bit.
8515 * emacs.c: Integer overflow minor fix.
8516 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8517 Define only if GNU_LINUX.
8518 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8520 * dispnew.c: Integer signedness and overflow fixes.
8521 Remove unnecessary forward decls, that were a maintenance hassle.
8522 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8524 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8525 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8526 (prepare_desired_row, line_draw_cost):
8527 Use int, not unsigned, where either works.
8528 (save_current_matrix, restore_current_matrix):
8529 Use ptrdiff_t, not size_t, where either works.
8530 (init_display): Check for overflow more accurately, and without
8531 relying on undefined behavior.
8533 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8534 Remove, replacing with the new symbols in lisp.h. All uses changed.
8535 * fileio.c (make_temp_name):
8536 * filelock.c (lock_file_1, lock_file):
8537 * xdisp.c (message_dolog):
8538 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8539 Use pMd etc. instead.
8540 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8541 replacing the pWIDE etc. symbols removed from editfns.c.
8543 * keyboard.h (num_input_events): Now uintmax_t.
8544 This is (very slightly) less likely to mess up due to wraparound.
8547 * buffer.c: Integer signedness fixes.
8548 (alloc_buffer_text, enlarge_buffer_text):
8549 Use ptrdiff_t rather than size_t when either will do, as we prefer
8552 * alloc.c: Integer signedness and overflow fixes.
8553 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8554 (__malloc_size_t): Default to size_t, not to int.
8555 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8556 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8557 Prefer ptrdiff_t to size_t when either would do, as we prefer
8559 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8560 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8561 Now const. Initialize with values that are in range even if char
8563 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8564 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8565 These functions do the right thing with sizes > 2**32.
8566 (check_depth): Now ptrdiff_t, not int.
8567 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8568 Adjust to new way of storing sizes. Check for size overflow bugs
8570 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8571 slightly wrong anyway, as it missed one instance of
8572 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8573 (refill_memory_reserve): Omit needless cast to size_t.
8574 (mark_object_loop_halt): Mark as externally visible.
8576 * xselect.c: Integer signedness and overflow fixes.
8577 (Fx_register_dnd_atom, x_handle_dnd_message):
8578 Use ptrdiff_t, not size_t, since we prefer signed.
8579 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8580 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8581 x_dnd_atoms_size and x_dnd_atoms_length.
8583 * doprnt.c: Prefer signed to unsigned when either works.
8585 * doprnt.c (doprnt):
8587 * xdisp.c (vmessage):
8588 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8589 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8590 prefer signed arithmetic to avoid comparison confusion.
8591 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8592 but is a bit tricky.
8594 Assume freestanding C89 headers, string.h, stdlib.h.
8595 * data.c, doprnt.c, floatfns.c, print.c:
8596 Include float.h unconditionally.
8597 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8598 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8599 * regex.c: Likewise for stddef.h, string.h.
8600 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8601 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8602 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8603 (STDC_HEADERS): Remove obsolete defines.
8604 * sysdep.c: Include limits.h unconditionally.
8606 Assume support for memcmp, memcpy, memmove, memset.
8607 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8608 * regex.c (memcmp, memcpy):
8609 Remove; we assume C89 now.
8611 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8612 (__malloc_safe_bcopy): Remove; no longer needed.
8614 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8615 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8616 well either way, and we prefer signed to unsigned.
8618 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8620 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8621 closes the connection while we're reading (bug#9182).
8623 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8625 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8626 are specified (Bug#9168).
8628 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8630 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8631 Found by GCC static checking and --with-wide-int on a 32-bit host.
8633 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8635 * xdisp.c (compute_display_string_pos): Fix logic of caching
8636 previous display string position. Initialize cached_prev_pos to
8637 -1. Fixes slow-down at the beginning of a buffer.
8639 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8641 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8642 for attrs[LFACE_FONTSET_INDEX].
8644 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8646 * xml.c (parse_region): Remove unused local
8647 that was recently introduced.
8649 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8651 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8652 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8654 * xdisp.c (move_it_in_display_line_to): Record the best matching
8655 position for TO_CHARPOS while scanning the line, and restore it on
8656 exit if none of the characters scanned was an exact match.
8657 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8658 when exact match is impossible due to invisible text, and the
8659 lines are truncated.
8661 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8663 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8666 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8668 Fix a significant slow-down of cursor motion with C-n, C-p,
8669 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8670 auto-repeat under bidi redisplay in fontified buffers.
8671 * xdisp.c (compute_stop_pos_backwards): New function.
8672 (next_element_from_buffer): Call compute_stop_pos_backwards to
8673 find a suitable prev_stop when we find ourselves before
8675 (reseat): Don't look for prev_stop, as that could mean a very long
8677 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8678 <cached_disp_overlay_modiff>: Cache for last found display string
8680 (compute_display_string_pos): Return the cached position if asked
8681 about the same buffer in the same area of character positions, and
8682 the buffer wasn't changed since the time the display string
8683 position was cached.
8685 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8687 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8688 is an integer, which is important for empty lines. (Bug#9149)
8690 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8692 * frame.c (Fmodify_frame_parameters): In tty case, update the
8693 default face if necessary (Bug#4238).
8695 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8697 * editfns.c (Fstring_to_char): No need to explain what a character
8698 is in the docstring (Bug#6576).
8700 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8702 * xml.c (parse_region): Make sure we always return a tree.
8704 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8706 * xml.c (parse_region): If a document contains only comments,
8709 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8711 * xml.c (make_dom): Return comments, too.
8713 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8716 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8717 and the surrounding thread.
8718 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8719 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8720 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8722 * s/openbsd.h (BROKEN_SIGIO): Define.
8723 * unexelf.c (unexec) [__OpenBSD__]:
8724 Don't update the .mdebug section of the Alpha COFF symbol table.
8726 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8728 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8731 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

8734 This fixes some race conditions on the permissions of any newly
8737 * alloc.c (valid_pointer_p): Use pipe, not open.
8738 This fixes some permissions issues when debugging.
8740 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8741 If fchown fails to set both uid and gid, try to set just gid,
8742 as that is sometimes allowed. Adjust the file's mode to eliminate
8743 setuid or setgid bits that are inappropriate if fchown fails.
8745 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8747 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8748 to compare Lisp_Objects.
8749 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

8759 symbol character follows.
8761 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8763 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8764 This works around a problem with the previous change to Fcopy_file.
8765 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8766 and without this change, GCC might complain about discarding
8767 fchown's return value.
8769 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8771 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8773 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8775 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8777 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8779 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8780 it's used from the C level.
8782 * process.c: Use the same condition for POLL_FOR_INPUT in both
8783 keyboard.c and process.c (bug#1858).
8785 2011-07-09 Lawrence Mitchell <wence@gmx.li>

8792 * doc.c (Fsubstitute_command_keys): Revert last change.
8794 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8796 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8797 quotes the next character, and doesn't affect other longer
8798 sequences (bug#8935).
8800 * lread.c (syms_of_lread): Clarify that is isn't only
8801 `eval-buffer' and `eval-defun' that's affected by
8802 `lexical-binding' (bug#8460).
8804 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8806 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8807 bidi redisplay when a line includes both an image and is truncated.
8809 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8811 Fix minor problems found by static checking.
8812 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8813 (elsz): Now a signed constant, not a size_t var. We prefer signed
8814 types to unsigned, to avoid integer comparison confusion. Without
8815 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8816 "cannot optimize loop, the loop counter may overflow", a symptom
8818 * indent.c (Fvertical_motion): Mark locals as initialized.
8819 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8821 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8823 * search.c (Fre_search_backward): Mention `case-fold-search' in
8824 all the re_search_* functions (bug#8138).

8844 buffer position was specified. Initialize paragraph_embedding to
8846 (reseat_to_string): Initialize the bidi iterator.
8847 (display_string): If we need to ignore text properties of
8848 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8849 original value of -1 will not work with bidi.)

8853 (compute_display_string_end): Support display properties on Lisp
8855 (init_iterator, reseat_1, reseat_to_string): Initialize the
8856 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8857 when iterating on a string not from display properties).
8858 (compute_display_string_pos, compute_display_string_end):
8859 Fix calculation of the object to scan. Fixes an error when using
8861 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8862 base_level_stop; instead, set base_level_stop to BEGV.
8863 Fixes crashes in vertical-motion.
8864 (next_element_from_buffer): Improve commentary for when
8865 the iterator is before prev_stop.
8866 (init_iterator): Initialize bidi_p from the default value of
8867 bidi-display-reordering, not from buffer-local value. Use the
8868 buffer-local value only if initializing for buffer iteration.
8869 (handle_invisible_prop): Support invisible properties on strings
8870 that are being bidi-reordered.
8871 (set_iterator_to_next): Support bidi reordering of C strings and

8889 parts of next_element_from_buffer, next_element_from_string, and
8890 next_element_from_c_string.
8891 (tool_bar_lines_needed, redisplay_tool_bar)
8892 (display_menu_bar): Force left-to-right direction. Add a FIXME
8893 comment for making that be controlled by a user option.

8907 pushed the iterator stack, restore the internal state of the bidi
8908 iterator by calling bidi_pop_it same number of times.
8909 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8910 and we are bidi-iterating, don't decrement the iterator position;
8911 instead, set the first_elt flag in the bidi iterator, to produce
8913 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8914 (push_display_prop): xassert that we are iterating a buffer.

8975 changed. Support iteration over a string. Support strings with
8976 display properties. Support unibyte strings. Fix the type of
8977 `len' according to what STRING_CHAR_AND_LENGTH expects.

9343 (clone_per_buffer_values): Don't assume that

9384 Random fixes. E.g., (random) never returned negative values.
9385 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9386 subseconds part to the entropy, as that's a bit more random.
9387 Prefer signed to unsigned, since the signedness doesn't matter and
9388 in general we prefer signed. When given a limit, use a
9389 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9390 latter isn't right if USE_2_TAGS_FOR_INTS.
9391 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9392 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9404 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9405 This is more efficient than Ffile_directory_p and avoids a minor race.
9407 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9409 * buffer.c (Foverlay_put): Say what the return value is
9412 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9413 is a directory before asking whether to use the file name
9415 (barf_or_query_if_file_exists): Make the "File is a directory"
9416 error be more correct.
9418 * fns.c (Frequire): Remove the mention of the .gz files, since
9419 that's installation-specific, but keep the mention of
9420 `get-load-suffixes'.
9422 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9424 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.
9425 Report string overflow if the output is too long.

9435 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9436 Also (re)move comments that are misplaced or no longer relevant.
9438 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9440 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9505 * Makefile.in (SETTINGS_LIBS): Fix typo.

9535 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9537 * eval.c (struct backtrace): Simplify and port the data structure.
9538 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9539 signed bit field, as this assumption is not portable and it makes
9540 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9541 "char debug_on_exit : 1" as this is not portable either; instead,
9542 use the portable "unsigned int debug_on_exit : 1". Remove unused
9543 member evalargs. Remove obsolete comments about cc bombing out.
9545 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9633 * process.c (wait_reading_process_output): Bypass select if
9634 waiting for a cell while ignoring keyboard input, and input is
9635 pending. Suggested by Jan Djärv (Bug#8869).

9713 Don't set size unless allocation succeeds.
9715 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9716 for sizes. Check for string overflow more accurately.
9717 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
9719 * macros.c: Integer and buffer overflow fixes.
9720 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9721 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

9727 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9729 * lread.c: Integer overflow fixes.
9730 (read_integer): Radix is now EMACS_INT, not int,
9731 to improve quality of diagnostics for out-of-range radices.
9732 Calculate buffer size correctly for out-of-range radices.

9734 read-circle numbers.
9735 (read_escape): Avoid int overflow.
9736 (Fload, openp, read_buffer_size, read1)
9737 (substitute_object_recurse, read_vector, read_list, map_obarray):

9751 (read_escape): Check for hex character overflow.
9753 2011-06-22 Leo Liu <sdl.web@gmail.com>
9755 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9756 Move to minibuffer.el.
9758 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9760 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9761 The following patches are for when GLYPH_DEBUG && !XASSERT.
9762 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9763 * dispnew.c (flush_stdout):
9764 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9765 Mark as externally visible.
9766 * dispnew.c (check_window_matrix_pointers): Now static.
9767 * dispnew.c (window_to_frame_vpos):
9768 * xfns.c (unwind_create_frame):
9769 * xterm.c (x_check_font): Remove unused local.
9770 * scroll.c (CHECK_BOUNDS):
9771 * xfaces.c (cache_fache): Rename local to avoid shadowing.

9773 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9774 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9775 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9777 (debug_method_add): Use va_list and vsprintf rather than relying
9778 on undefined behavior with wrong number of arguments.
9779 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9780 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9781 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9782 since we're not interested in debugging glyphs with old libraries.
9783 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9784 GCC 4.6.0's static checking.
9786 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9788 Integer overflow and signedness fixes (Bug#8873).

9797 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9798 (x_create_bitmap_from_xpm_data):
9799 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9800 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9802 * xfaces.c (load_pixmap):

9805 (.bitmaps_last, struct x_output.icon_bitmap):
9806 Use ptrdiff_t, not int, for bitmap indexes.
9807 (x_allocate_bitmap_record): Check for size overflow.
9808 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9810 Use ptrdiff_t, not int, for overlay counts.
9811 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9812 * editfns.c (overlays_around, get_pos_property):
9813 * textprop.c (get_char_property_and_overlay):
9814 * xdisp.c (next_overlay_change, note_mouse_highlight):
9815 * xfaces.c (face_at_buffer_position):
9816 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9817 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9818 (Fnext_overlay_change, Fprevious_overlay_change)
9819 (mouse_face_overlay_overlaps, Foverlays_in):
9820 Use ptrdiff_t, not int, for sizes.
9821 (overlays_at, overlays_in): Check for size-calculation overflow.
9823 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9825 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9826 (x_session_initialize): Do not assume string length fits in int.
9828 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9829 This is unlikely, but can occur if DPI is outlandish.
9831 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9832 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9834 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9835 * xrdb.c (magic_file_p, search_magic_path):
9836 Omit last arg SUFFIX; it was always 0. All callers changed.
9837 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9839 * xfont.c (xfont_match): Avoid need for strlen.
9841 * xfns.c: Don't assume strlen fits in int.

9845 not unsigned long, as we prefer signed integers. All callers changed.
9846 Detect integer overflow in repeat count.
9847 (message_dolog): Don't assume print length fits in 39 bytes.
9848 (display_mode_element): Don't assume strlen fits in int.
9850 * termcap.c: Don't assume sizes fit in int and never overflow.
9851 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9852 (gobble_line): Check for size-calculation overflow.
9854 * minibuf.c (Fread_buffer):
9855 * lread.c (intern, intern_c_string):
9856 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9857 Don't assume string length fits in int.
9859 * keyboard.c (parse_tool_bar_item):
9860 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9862 * font.c: Don't assume string length fits in int.
9863 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9864 Use ptrdiff_t, not int.
9865 (font_intern_prop): Don't assume string length fits in int.
9866 Don't assume integer property fits in fixnum.
9867 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9869 * filelock.c: Fix some buffer overrun and integer overflow issues.
9870 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9871 Reformulate so as not to need the command string.
9872 Invoke gzip -cd rather than gunzip, as it's more portable.
9873 (lock_info_type, lock_file_1, lock_file):
9874 Don't assume pid_t and time_t fit in unsigned long.
9875 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9876 (current_lock_owner): Prefer signed type for sizes.
9877 Use memcpy, not strncpy, where memcpy is what is really wanted.
9878 Don't assume (via atoi) that time_t and pid_t fit in int.
9879 Check for time_t and/or pid_t out of range, e.g., via a network share.
9880 Don't alloca where an auto var works fine.
9882 * fileio.c: Fix some integer overflow issues.
9883 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9884 Don't assume string length fits in int.
9885 (directory_file_name): Don't assume string length fits in long.
9886 (make_temp_name): Don't assume pid fits in int, or that its print
9887 length is less than 20.
9889 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9891 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9893 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

9907 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9909 * lread.c (invalid_syntax): Omit length argument.
9910 All uses changed. This doesn't fix a bug, but it simplifies the
9911 code away from its former Hollerith-constant appearance, and it's
9912 one less 'int' to worry about when looking at integer-overflow issues.
9913 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9915 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9916 This didn't break anything, but it didn't help either.
9917 It's confusing to put a bogus integer in a place where the actual
9918 value does not matter.
9919 (LIST_END_P): Remove unused macro and its bogus comment.
9920 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9922 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9923 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9925 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9926 We prefer signed types, and the value cannot exceed the EMACS_INT
9927 range anyway (because otherwise the length would not be representable).
9928 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9929 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9930 This avoids a GCC warning when WIDE_EMACS_INT.
9932 * indent.c (sane_tab_width): New function.
9933 (current_column, scan_for_column, Findent_to, position_indentation)
9934 (compute_motion): Use it. This is just for clarity.
9935 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9937 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9939 * lisp.h (lint_assume): New macro.
9940 * composite.c (composition_gstring_put_cache):
9941 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9943 * editfns.c, insdel.c:
9944 Omit unnecessary forward decls, to simplify future changes.
9946 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9948 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9950 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9951 Use much-faster test for byte-length change.
9952 Don't assume string byte-length fits in 'int'.
9953 Check that character arg fits in 'int'.
9954 (mapcar1): Declare byte as byte, for clarity.
9956 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9958 * fns.c (concat): Catch string overflow earlier.
9959 Do not rely on integer wraparound.
9961 * dispextern.h (struct it.overlay_strings_charpos)
9962 (struct it.selective): Now EMACS_INT, not int.
9963 * xdisp.c (forward_to_next_line_start)
9964 (back_to_previous_visible_line_start)
9965 (reseat_at_next_visible_line_start, next_element_from_buffer):
9966 Don't arbitrarily truncate the value of 'selective' to int.
9968 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9970 * composite.c: Don't truncate sizes to 'int'.
9971 (composition_gstring_p, composition_reseat_it)
9972 (composition_adjust_point): Use EMACS_INT, not int.
9973 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9974 not EMACS_UINT, for indexes.
9976 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9978 * buffer.c: Include <verify.h>.
9979 (struct sortvec.priority, struct sortstr.priority):
9980 Now EMACS_INT, not int.
9981 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9982 (struct sortstr.size, record_overlay_string)
9983 (struct sortstrlist.size, struct sortlist.used):
9984 Don't truncate size to int.
9985 (record_overlay_string): Check for size-calculation overflow.
9986 (init_buffer_once): Check at compile-time, not run-time.
9988 2011-06-22 Jim Meyering <meyering@redhat.com>
9990 Don't leak an XBM-image-sized buffer
9991 * image.c (xbm_load): Free the image buffer after using it.
9993 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9996 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9997 that Sun C diagnosed.
9998 * fns.c (secure_hash): Fix pointer signedness issue.
9999 * intervals.c (static_offset_intervals): New function.
10000 (offset_intervals): Use it.
10002 2011-06-21 Leo Liu <sdl.web@gmail.com>
10005 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10008 * fns.c (secure_hash): Rename from crypto_hash_function and change
10009 the first arg to accept symbols.
10010 (Fsecure_hash): New primitive.
10011 (syms_of_fns): New symbols.
10013 2011-06-20 Deniz Dogan <deniz@dogan.se>
10015 * process.c (Fset_process_buffer): Clarify return value in
10018 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10020 * dispnew.c (add_window_display_history): Use BVAR.
10022 * xdisp.c (debug_method_add): Use BVAR.
10023 (check_window_end, dump_glyph_matrix, dump_glyph)
10024 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10026 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10029 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10030 check till after the cache is created in init_frame_faces.
10032 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10034 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10036 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10038 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10039 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10040 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10042 Improve buffer-overflow checking (Bug#8873).
10043 * fileio.c (Finsert_file_contents):
10044 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10045 Remove the old (too-loose) buffer overflow checks.
10046 They weren't needed, since make_gap checks for buffer overflow.
10047 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10048 The old code merely checked for Emacs fixnum overflow, and relied
10049 on undefined (wraparound) behavior. The new code avoids undefined
10050 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10052 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10053 Tune. Don't use wider integers than needed. Don't use alloca.
10054 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10056 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10058 * insdel.c, lisp.h (buffer_overflow): New function.
10059 (insert_from_buffer_1, replace_range, replace_range_2):
10060 * insdel.c (make_gap_larger):
10061 * editfns.c (Finsert_char):
10062 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10064 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10066 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10068 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10070 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10071 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10073 * fileio.c: Don't assume EMACS_INT fits in off_t.
10074 (emacs_lseek): New static function.
10075 (Finsert_file_contents, Fwrite_region): Use it.
10076 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10078 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10080 * fns.c: Don't overflow int when computing a list length.
10081 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10082 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10083 truncation on 64-bit hosts. Check for QUIT every
10084 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10085 faster and is responsive enough.
10086 (Flength): Report an error instead of overflowing an integer.
10087 (Fsafe_length): Return a float if the value is not representable
10088 as a fixnum. This shouldn't happen except in contrived situations.
10089 (Fnthcdr, Fsort): Don't assume list length fits in int.
10090 (Fcopy_sequence): Don't assume vector length fits in int.
10092 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10093 (header_size, word_size): New constants.
10094 (allocate_vectorlike): Don't check size overflow here.
10095 (allocate_vector): Check it here instead, since this is the only
10096 caller of allocate_vectorlike that could cause overflow.
10097 Check that the new vector's length is representable as a fixnum.
10099 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10100 The previous code was bogus. For example, next_almost_prime (32)
10101 returned 39, which is undesirable as it is a multiple of 3; and
10102 next_almost_prime (24) returned 25, which is a multiple of 5 so
10103 why was the code bothering to check for multiples of 7?
10105 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10107 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10109 Variadic C functions now count arguments with ptrdiff_t.
10110 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10111 Back then I didn't know that the Emacs coding style prefers signed int.
10112 Also, in the meantime I found a few more instances where arguments
10113 were being counted with int, which may truncate counts on 64-bit
10114 machines, or EMACS_INT, which may be unnecessarily wide.
10115 * lisp.h (struct Lisp_Subr.function.aMANY)
10116 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10117 Arg counts are now ptrdiff_t, not size_t.
10118 All variadic functions and their callers changed accordingly.
10119 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10120 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10121 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10122 * callint.c (Fcall_interactively): Check arg count for overflow,
10123 to avoid potential buffer overrun. Use signed char, not 'int',
10124 for 'varies' array, so that we needn't bother to check its size
10125 calculation for overflow.
10126 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10127 * eval.c (apply_lambda):
10128 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10129 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10130 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10132 * callint.c (Fcall_interactively): Don't use index var as event count.
10134 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10135 * mem-limits.h (SIZE): Remove; no longer used.
10137 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10139 Remove unnecessary casts.
10140 * xterm.c (x_term_init):
10141 * xfns.c (x_set_border_pixel):
10142 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10143 These aren't needed now that we assume ANSI C.
10145 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10146 It's more likely to cause problems (due to unsigned overflow)
10149 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10151 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10153 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10155 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10157 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10159 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10161 GLYPH_CODE_FACE returns EMACS_INT, not int.
10162 * dispextern.h (merge_faces):
10163 * xfaces.c (merge_faces):
10164 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10165 Don't assume EMACS_INT fits in int.
10167 * character.h (CHAR_VALID_P): Remove unused parameter.
10168 * fontset.c, lisp.h, xdisp.c: All uses changed.
10170 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10172 * fns.c (concat): Minor tuning based on overflow analysis.
10173 This doesn't fix any bugs. Use int to hold character, instead
10174 of constantly refetching from Emacs object. Use XFASTINT, not
10175 XINT, for value known to be a character. Don't bother comparing
10176 a single byte to 0400, as it's always less.
10178 * floatfns.c (Fexpt):
10179 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10181 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10184 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10186 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10187 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10188 incorrectly succeed when S was a string, because 4294967386 was
10189 truncated before it was used.
10191 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10192 Otherwise, an out-of-range integer could cause undefined behavior
10195 * composite.c: Use int, not EMACS_INT, for characters.
10196 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10197 EMACS_INT, for values that are known to be in character range.
10198 This doesn't fix any bugs but is the usual style inside Emacs and
10199 may generate better code on 32-bit machines.
10201 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10202 This is for reasons similar to the recent CHAR_STRING fix.
10203 * charset.c (Fencode_char): Check that character arg is actually
10204 a character. Pass an int to ENCODE_CHAR.
10205 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10206 wider than 'int', as a compile-time check to prevent future regressions
10209 * character.c (char_string): Remove unnecessary casts.
10211 Make sure a 64-bit char is never passed to CHAR_STRING.
10212 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10213 by silently ignoring the top 32 bits, allowing some values
10214 that were far too large to be valid characters.
10215 * character.h: Include <verify.h>.
10216 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10217 arguments are no wider than unsigned, as a compile-time check
10218 to prevent future regressions in this area.
10220 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10221 (Fsubst_char_in_region):
10223 * xdisp.c (decode_mode_spec_coding):
10224 Adjust to CHAR_STRING's new requirement.
10225 * editfns.c (Finsert_char, Fsubst_char_in_region):
10226 * fns.c (concat): Check that character args are actually
10227 characters. Without this test, these functions did the wrong
10228 thing with wildly out-of-range values on 64-bit hosts.
10230 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10231 These casts should not be needed on 32-bit hosts, either.
10232 * keyboard.c (read_char):
10233 * lread.c (Fload): Remove casts to unsigned.
10235 * lisp.h (UNSIGNED_CMP): New macro.
10236 This fixes comparison bugs on 64-bit hosts.
10237 (ASCII_CHAR_P): Use it.
10238 * casefiddle.c (casify_object):
10239 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10240 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10241 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10242 * dispextern.h (FACE_FROM_ID):
10243 * keyboard.c (read_char): Use UNSIGNED_CMP.
10245 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10246 not to EMACS_INT, to avoid GCC warning.
10248 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10250 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10251 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10252 isn't needed on 32-bit machines.
10254 * buffer.c (Fgenerate_new_buffer_name):
10255 Use EMACS_INT for count, not int.
10256 (advance_to_char_boundary): Return EMACS_INT, not int.
10258 * data.c (Qcompiled_function): Now static.
10260 * window.c (window_body_lines): Now static.
10262 * image.c (gif_load): Rename local to avoid shadowing.
10264 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10265 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10266 * alloc.c (make_save_value): Integer argument is now of type
10267 ptrdiff_t, not int.
10268 (mark_object): Use ptrdiff_t, not int.
10269 * lisp.h (pD): New macro.
10270 * print.c (print_object): Use it.
10272 * alloc.c: Use EMACS_INT, not int, to count objects.
10273 (total_conses, total_markers, total_symbols, total_vector_size)
10274 (total_free_conses, total_free_markers, total_free_symbols)
10275 (total_free_floats, total_floats, total_free_intervals)
10276 (total_intervals, total_strings, total_free_strings):
10277 Now EMACS_INT, not int. All uses changed.
10278 (Fgarbage_collect): Compute overall total using a double, so that
10279 integer overflow is less likely to be a problem. Check for overflow
10280 when converting back to an integer.
10281 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10282 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10283 These were 'int' variables that could overflow on 64-bit hosts;
10284 they were never used, so remove them instead of repairing them.
10285 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10286 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10287 Previously, this ceilinged at INT_MAX, but that doesn't work on
10289 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10291 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10292 (allocate_vectorlike): Check for ptrdiff_t overflow.
10293 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10294 when a (possibly-narrower) signed value would do just as well.
10295 We prefer using signed arithmetic, to avoid comparison confusion.
10297 * alloc.c: Catch some string size overflows that we were missing.
10298 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10299 for convenience in STRING_BYTES_MAX.
10300 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10301 The definition here is exact; the one in lisp.h was approximate.
10302 (allocate_string_data): Check for string overflow. This catches
10303 some instances we weren't catching before. Also, it catches
10304 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10305 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10306 and ptrdiff_t and EMACS_INT are both 64 bits.
10308 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10309 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10310 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10312 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10314 * alloc.c (Fmake_string): Check for out-of-range init.
10316 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10318 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10320 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10322 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10323 xg_get_default_scrollbar_width.
10325 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10326 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10327 (style_changed_cb): Call update_theme_scrollbar_width and call
10328 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10329 all frames (Bug#8505).
10330 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10331 Call gtk_window_set_resizable if HAVE_GTK3.
10332 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10333 and height if HAVE_GTK3 (Bug#8505).
10334 (scroll_bar_width_for_theme): New variable.
10335 (update_theme_scrollbar_width): New function.
10336 (xg_get_default_scrollbar_width): Move code to
10337 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10338 (xg_initialize): Call update_theme_scrollbar_width.
10340 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10342 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10344 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10346 * frame.c (make_frame): Call other_buffer_safely instead of
10349 * window.c (temp_output_buffer_show): Call display_buffer with
10350 second argument Vtemp_buffer_show_specifiers and reset latter
10351 immediately after the call.
10352 (Vtemp_buffer_show_specifiers): New variable.
10353 (auto_window_vscroll_p, next_screen_context_lines)
10354 (Vscroll_preserve_screen_position): Remove leading asterisks from
10357 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10359 Fix minor problems found by GCC 4.6.0 static checking.
10360 * buffer.c (Qclone_number): Remove for now, as it's unused.
10361 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10362 (record_buffer): Remove unused local.
10363 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10364 (set_frame_buffer_list): Remove; unused.
10365 * frame.h (other_visible_frames): Remove decl.
10366 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10367 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10368 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10370 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10371 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10372 Define only if HAVE_GPM.
10373 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10374 (update_hints_inhibit): Remove; never set. All uses removed.
10375 * widgetprv.h (emacsFrameClassRec): Remove decl.
10376 * window.c (delete_deletable_window): Now returns void, since it
10377 wasn't returning anything.
10378 (compare_window_configurations): Remove unused locals.
10379 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10380 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10381 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10382 the same widths as pointers. This follows up on the 2011-05-06 patch.
10383 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10384 * xterm.h: Likewise.
10385 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10387 2011-06-12 Juanma Barranquero <lekktu@gmail.com>

10390 (LISP_H): Add lib/intprops.h.
10392 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10394 * image.c (gif_load): Add animation frame delay to the metadata.
10395 (syms_of_image): Use DEFSYM. New symbol `delay'.
10397 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10399 * window.c (delete_deletable_window): Re-add.
10400 (Fset_window_configuration): Rewrite to handle dead buffers and
10401 consequently deletable windows.
10402 (window_tree, Fwindow_tree): Remove. Supply functionality in
10404 (compare_window_configurations): Simplify code.
10406 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10408 * image.c (imagemagick_load_image): Fix type mismatch.
10409 (Fimagemagick_types): Likewise.
10411 * window.h (replace_buffer_in_windows): Declare.
10413 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10415 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10416 Qclone_number. Remove external declaration of Qdelete_window.
10417 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10419 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10420 Run Qbuffer_list_update_hook if allowed.
10421 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10422 buffer list implementation.
10423 (other_buffer_safely): New function.
10424 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10425 calls to replace_buffer_in_windows and
10426 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10428 (record_buffer): Inhibit quitting and rewrite using quittable
10429 functions. Run Qbuffer_list_update_hook if allowed.
10430 (Frecord_buffer, Funrecord_buffer): New functions.
10431 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10432 Move switch-to-buffer to window.el.
10433 (bury-buffer): Move to window.el.
10434 (Vbuffer_list_update_hook): New variable.
10436 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10439 * window.h (resize_frame_windows): Move up in code.
10440 (Fwindow_frame): Remove EXFUN.
10441 (replace_buffer_in_all_windows): Remove prototype.
10442 (replace_buffer_in_windows_safely): Add prototype.
10444 * window.c: Declare Qdelete_window static again. Move down
10445 declaration of select_count.
10446 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10447 (Fother_window): Move to window.el.
10448 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10449 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10450 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10452 (replace_buffer_in_windows): Implement by calling
10453 Qreplace_buffer_in_windows.
10454 (replace_buffer_in_all_windows): Remove with some functionality
10455 moved into replace_buffer_in_windows_safely.
10456 (replace_buffer_in_windows_safely): New function.
10457 (select_window_norecord, select_frame_norecord): Move in front
10458 of run_window_configuration_change_hook. Remove now obsolete
10460 (Fset_window_buffer): Rewrite doc-string.
10461 Call Qrecord_window_buffer.
10462 (keys_of_window): Move binding for other-window to window.el.
10464 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10466 * dispextern.h (struct image): Replace data member, whose int_val
10467 and ptr_val fields were not used by anything, with a single
10470 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10471 (gif_clear_image, gif_load, imagemagick_load_image)
10472 (gs_clear_image, gs_load): Callers changed.
10474 2011-06-10 Paul Eggert <eggert@cs.ucla.edu>
10476 * buffer.h: Include <time.h>, for time_t.
10477 Needed to build on FreeBSD 8.2. Problem reported by Herbert J. Skuhra.
10479 Fix minor problems found by static checking.

10921 the display property, but just return a value indicating whether
10922 the display property will replace the characters it covers.
10923 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10924 frame_window_p members of struct bidi_it.
10925 (compute_display_string_pos, compute_display_string_end):
10927 (push_it): Accept second argument POSITION, where pop_it should
10928 jump to continue iteration.
10929 (reseat_1): Initialize bidi_it.disp_pos.
10931 * keyboard.c (adjust_point_for_property): Adjust the call to
10932 display_prop_intangible_p to its new signature.

10937 (compute_display_string_pos, compute_display_string_end):
10938 Declare prototypes.
10939 (struct bidi_it): New members nchars and disp_pos. ch_len is now
10942 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
10944 Malloc failure behavior now depends on size of allocation.
10945 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
10946 * lisp.h: Change signatures accordingly.
10947 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
10948 All callers changed. (Bug#8762)
10950 * gnutls.c: Use Emacs's memory allocators.
10951 Without this change, the gnutls library would invoke malloc etc.
10952 directly, which causes problems on non-SYNC_INPUT hosts, and which
10953 runs afoul of improving memory_full behavior. (Bug#8761)
10954 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10955 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10956 xfree instead of the default malloc, realloc, free.
10957 (Fgnutls_boot): No need to check for memory allocation failure,
10958 since xmalloc does that for us.
10960 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
10961 * category.c (hash_get_category_set):
10962 * ccl.c (ccl_driver):

10974 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
10975 (Fsxhash, Fgethash, Fputhash, Fmaphash):
10976 * image.c (make_image, search_image_cache, lookup_image)
10977 (xpm_put_color_table_h):
10978 * lisp.h (struct Lisp_Hash_Table):
10979 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
10980 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10981 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10982 * alloc.c (allocate_vectorlike):
10983 Check for overflow in vector size calculations.
10984 * ccl.c (ccl_driver):
10985 Check for overflow when converting EMACS_INT to int.
10986 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10987 need to be updated by these changes.
10988 * fns.c (make_hash_table, maybe_resize_hash_table):
10989 Check for integer overflow with large hash tables.
10990 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10991 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10992 (SXHASH_REDUCE): New macro.
10993 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10994 Use it instead of discarding useful hash info with large hash values.
10995 (sxhash_float): New function.
10996 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10997 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10998 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10999 Rewrite to use FIXNUM_BITS, as this simplifies things.
11000 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11001 Adjust signatures to match updated version of code.
11002 (consing_since_gc): Now EMACS_INT, since a single hash table can
11003 use more than INT_MAX bytes.
11005 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11007 Make it possible to build with GCC-4.6+ -O2 -flto.
11009 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11011 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11013 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11014 Call minibuffer-inactive-mode.
11016 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11018 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11019 Update dependencies.
11021 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11023 * data.c (init_data): Remove code for UTS, this system is not
11026 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11028 Don't force ./temacs to start in terminal mode.
11030 * frame.c (make_initial_frame): Initialize faces in all cases, not
11031 only when CANNOT_DUMP is defined.
11032 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11034 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11036 * dispnew.c (add_window_display_history): Use const for the string
11037 pointer. Remove declaration, not needed.
11039 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11041 Use 'inline', not 'INLINE'.
11042 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11043 * alloc.c, fontset.c (INLINE): Remove.
11044 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11045 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11046 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11047 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11048 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11050 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11052 Make it possible to run ./temacs.
11054 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11055 syms_of_callproc does the same thing. Remove test for
11056 "initialized", do it in the caller.
11057 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11059 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11061 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11062 (read_minibuf): Use get_minibuffer.
11063 (syms_of_minibuf): Use DEFSYM.
11064 (Qmetadata): New var.
11065 * data.c (Qbuffer): Don't make it static.
11066 (syms_of_data): Use DEFSYM.
11068 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11070 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11071 (CCL_CODE_MIN): New macro.
11073 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11075 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11077 * eval.c (Qdebug): Now static.
11078 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11079 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11080 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11082 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11084 * image.c: Various fixes to ImageMagick code comments.
11085 (Fimagemagick_types): Doc fix.
11087 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11089 Minor fixes prompted by GCC 4.6.0 warnings.
11091 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11093 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11094 (x_clipboard_manager_save_all): Move extern decl to ...
11095 * xterm.h: ... here, so that it can be checked for consistency.
11097 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11099 * xselect.c (x_clipboard_manager_save_frame)
11100 (x_clipboard_manager_save_all): New functions.
11101 (Fx_clipboard_manager_save): Lisp function deleted.
11103 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11104 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11106 * xterm.h: Update prototype.
11108 2011-05-28 William Xu <william.xwl@gmail.com>
11110 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11111 exiting (Bug#8239).
11113 2011-05-28 Jim Meyering <meyering@redhat.com>
11115 Avoid a sign-extension bug in crypto_hash_function.
11116 * fns.c (to_uchar): Define.
11117 (crypto_hash_function): Use it to convert some newly-signed
11118 variables to unsigned, to avoid sign-extension bugs. For example,
11119 without this change, (md5 "truc") would evaluate to
11120 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11121 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11122 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11124 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11126 Integer overflow fixes.
11128 * dbusbind.c: Serial number integer overflow fixes.
11129 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11130 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11131 to hold a serial number that is too large for a fixnum.
11132 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11133 Check for serial numbers out of range. Decode any serial number
11134 that was so large that it became a float. (Bug#8722)
11136 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11137 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11138 Use XFASTINT rather than XUINT when numbers are nonnegative.
11139 (xd_append_arg, Fdbus_method_return_internal):
11140 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11141 arguments, check that Lisp number is nonnegative, rather than
11142 silently wrapping negative numbers around. (Bug#8722)
11143 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11146 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11148 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11150 ccl: Add integer overflow checks.
11151 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11152 (IN_INT_RANGE): New macros.
11153 (ccl_driver): Use them to check for integer overflow when
11154 decoding a CCL program. Many of the new checks are whether XINT (x)
11155 fits in int; it doesn't always, on 64-bit hosts. The new version
11156 doesn't catch all possible integer overflows, but it's an
11157 improvement. (Bug#8719)
11159 * alloc.c (make_event_array): Use XINT, not XUINT.
11160 There's no need for unsigned here.
11162 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11163 This follows up to the 2011-05-06 change that substituted uintptr_t
11164 for EMACS_INT. This case wasn't caught back then.
11166 Rework Fformat to avoid integer overflow issues.
11167 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11168 now (part of C89). Include <verify.h>.
11169 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11170 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11171 (Fformat): Avoid the prepass trying to compute sizes; it was only
11172 approximate and thus did not catch overflow reliably. Instead, walk
11173 through the format just once, formatting and computing sizes as we go,
11174 checking for integer overflow at every step, and allocating a larger
11175 buffer as needed. Keep track separately whether the format is
11176 multibyte. Keep only the most-recently calculated precision, rather
11177 than them all. Record whether each argument has been converted to
11178 string. Use EMACS_INT, not int, for byte and char and arg counts.
11179 Support field widths and precisions larger than INT_MAX. Avoid
11180 sprintf's undefined behavior with conversion specifications such as %#d
11181 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11182 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11183 formatting out-of-range floating point numbers with int
11184 formats. (Bug#8668)
11186 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11188 * data.c: Avoid integer truncation in expressions involving floats.
11189 * data.c: Include <intprops.h>.
11190 (arith_driver): When there's an integer overflow in an expression
11191 involving floating point, convert the integers to floating point
11192 so that the resulting value does not suffer from catastrophic
11193 integer truncation. For example, on a 64-bit host (* 4
11194 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11195 Do not rely on undefined behavior after integer overflow.
11197 merge count_size_as_multibyte, parse_str_to_multibyte
11198 * character.c, character.h (count_size_as_multibyte):
11199 Rename from parse_str_to_multibyte; all uses changed.
11200 Check for integer overflow.
11201 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11202 since it's now a duplicate of the other. This is more of
11203 a character than a buffer op, so better that it's in character.c.
11204 * fns.c, print.c: Adjust to above changes.
11206 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11208 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11210 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11212 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11213 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11214 (x_clipboard_manager_save): Now static.
11215 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11217 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11218 (crypto_hash_function): Now static.
11219 Fix pointer signedness problems. Avoid unnecessary initializations.
11221 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11223 * termhooks.h (Vselection_alist): Make it terminal-local.
11225 * terminal.c (create_terminal): Initialize it.
11227 * xselect.c: Support for clipboard managers.
11228 (Vselection_alist): Move to termhooks.h as terminal-local var.
11229 (LOCAL_SELECTION): New macro.
11230 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11231 (symbol_to_x_atom): Remove gratuitous arg.
11232 (x_handle_selection_request, lisp_data_to_selection_data)
11233 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11234 (x_own_selection, x_get_local_selection, x_convert_selection):
11235 New arg, specifying work frame. Use terminal-local Vselection_alist.
11236 (some_frame_on_display): Delete unused function.
11237 (Fx_own_selection_internal, Fx_get_selection_internal)
11238 (Fx_disown_selection_internal, Fx_selection_owner_p)
11239 (Fx_selection_exists_p): New optional frame arg.
11240 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11241 (x_handle_selection_clear): Don't treat other terminals with the
11242 same keyboard specially. Use the terminal-local Vselection_alist.
11243 (x_clear_frame_selections): Use Frun_hook_with_args.
11245 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11247 * xterm.h: Add support for those atoms.
11249 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11251 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11252 (converted_selections, conversion_fail_tag): New global variables.
11253 (x_selection_request_lisp_error): Free the above.
11254 (x_get_local_selection): Remove unnecessary code.
11255 (x_reply_selection_request): Args changed; handle arbitrary array
11256 of converted selections stored in converted_selections.
11257 Separate the XChangeProperty and SelectionNotify steps.
11258 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11259 (x_convert_selection): New function.
11260 (x_handle_selection_event): Simplify.
11261 (x_get_foreign_selection): Don't ignore incoming requests while
11262 waiting for an answer; this will fail when we implement
11263 SAVE_TARGETS, and seems unnecessary anyway.
11264 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11265 (Vx_sent_selection_functions): Doc fix.
11267 2011-05-26 Leo Liu <sdl.web@gmail.com>
11269 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11271 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11273 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11275 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11276 for fringe update if it has periodic bitmap.
11277 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11278 and fringe_bitmap_periodic_p.
11280 * fringe.c (get_fringe_bitmap_data): New function.
11281 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11282 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11283 row. Mark glyph row for fringe update if periodicity changed.
11285 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11286 for fringe update unless it has periodic bitmap.
11288 2011-05-25 Kenichi Handa <handa@m17n.org>

11306 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11307 Remove macros that are defined and never used.
11308 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11310 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11312 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11313 (Fx_get_selection_internal): Minor cleanup.

11341 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11343 * systime.h (Time): Define only if emacs is defined.
11344 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11345 where the include path doesn't have X11/X.h by default. See
11346 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11348 2011-05-20 Kenichi Handa <handa@m17n.org>
11350 * composite.c (find_automatic_composition): Fix previous change.
11352 2011-05-20 Glenn Morris <rgm@gnu.org>
11354 * lisp.mk: New file, split from Makefile.in.
11355 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11356 (shortlisp): Remove.
11357 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11359 2011-05-19 Glenn Morris <rgm@gnu.org>
11361 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11362 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11363 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11364 (lisp): Set the order to that of loadup.el.
11365 (shortlisp): Make it a copy of $lisp.
11366 (SOME_MACHINE_LISP): Remove.
11367 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11368 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11370 2011-05-18 Kenichi Handa <handa@m17n.org>
11372 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11373 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11374 (find_automatic_composition): Mostly rewrite for efficiency.
11376 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11378 * makefile.w32-in: Update dependencies.
11380 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11382 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11383 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11385 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11387 Fix some integer overflow issues, such as string length overflow.
11389 * insdel.c (count_size_as_multibyte): Check for string overflow.
11391 * character.c (lisp_string_width): Check for string overflow.
11392 Use EMACS_INT, not int, for string indexes and lengths; in
11393 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11394 the resulting string length overflows an EMACS_INT; instead,
11395 report a string overflow if no precision given. When checking for
11396 precision exhaustion, use a check that cannot possibly have
11397 integer overflow. (Bug#8675)
11398 * character.h (lisp_string_width): Adjust to new signature.
11400 * alloc.c (string_overflow): New function.
11401 (Fmake_string): Use it. This doesn't change behavior, but saves
11402 a few bytes and will simplify future changes.
11403 * character.c (string_escape_byte8): Likewise.
11404 * lisp.h (string_overflow): New decl.
11406 Fixups, following up to the user-interface timestamp change.
11407 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11408 for UI timestamps, instead of unsigned long.
11409 * msdos.c (mouse_get_pos): Likewise.
11410 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11411 * w32gui.h (Time): Define by including "systime.h" rather than by
11412 declaring it ourselves. (Bug#8664)
11414 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11415 * image.c (clear_image_cache): Likewise.
11417 * term.c (term_mouse_position): Don't assume time_t wraparound.
11419 Be more systematic about user-interface timestamps.
11420 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11421 and sometimes 'EMACS_UINT', to represent these timestamps.
11422 This change causes it to use 'Time' uniformly, as that's what X uses.
11423 This makes the code easier to follow, and makes it easier to catch
11424 integer overflow bugs such as Bug#8664.
11425 * frame.c (Fmouse_position, Fmouse_pixel_position):
11426 Use Time, not unsigned long, for user-interface timestamps.
11427 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11428 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11429 * keyboard.h (last_event_timestamp): Likewise.
11430 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11431 * menu.h (xmenu_show): Likewise.
11432 * term.c (term_mouse_position): Likewise.
11433 * termhooks.h (struct input_event.timestamp): Likewise.
11434 (struct terminal.mouse_position_hook): Likewise.
11435 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11436 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11437 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11438 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11439 what it was before.
11440 * menu.h, termhooks.h: Include "systime.h", for Time.
11442 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11443 Don't assume that the difference between two unsigned long values
11444 can fit into an integer. At this point, we know button_down_time
11445 <= event->timestamp, so the difference must be nonnegative, so
11446 there's no need to cast the result if double-click-time is
11447 nonnegative, as it should be; check that it's nonnegative, just in
11448 case. This bug is triggered when events are more than 2**31 ms
11449 apart (about 25 days). (Bug#8664)
11451 * xselect.c (last_event_timestamp): Remove duplicate decl.
11452 (x_own_selection): Remove needless cast to unsigned long.
11454 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11455 that always fit in int. Use a sentinel instead of a counter, to
11456 avoid a temp and to allay GCC's concerns about possible int overflow.
11457 * frame.h (struct frame): Use int for menu_bar_items_used
11458 instead of EMACS_INT, since it always fits in int.
11460 * menu.c (grow_menu_items): Check for int overflow.
11462 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11464 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11465 Before, the code was not consistent. These values cannot exceed
11466 2**31 - 1 so there's no need to make them unsigned.
11467 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11468 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11469 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11471 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11473 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11474 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11475 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11476 presumably because the widths might not match.
11478 * window.c (size_window): Avoid needless test at loop start.
11480 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11482 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11484 2011-05-12 Drew Adams <drew.adams@oracle.com>
11486 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11488 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11490 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11491 `width' to `bar_area_x' and `bar_area_width', respectively.
11492 (x_scroll_run): Take account of fringe background extension.
11494 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11495 Rename local vars `left' and `width' to `bar_area_x' and
11496 `bar_area_width', respectively.
11497 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11498 background extension.
11500 2011-05-10 Jim Meyering <meyering@redhat.com>
11502 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11504 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11506 * image.c (Finit_image_library): Return t for built-in image types,
11507 like pbm and xbm. (Bug#8640)
11509 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11511 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11513 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11515 * w32console.c (Fset_screen_color): Doc fix.
11516 (Fget_screen_color): New function.
11517 (syms_of_ntterm): Defsubr it.
11519 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11520 unlink the temporary file if Fcall_process didn't create it in the
11522 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11523 child process will be redirected to a file specified with `:file'.
11524 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11525 cue to call_process_cleanup not to close that handle.
11527 2011-05-07 Ben Key <bkey76@gmail.com>
11529 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11530 one of two shell specific rules, either bootstrap-temacs-CMD or
11531 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11532 to the previous implementation of the bootstrap-temacs rule.
11533 The bootstrap-temacs-CMD rule is similar to the previous
11534 implementation of the bootstrap-temacs rule except that it
11535 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11538 These changes, along with some changes to nt/configure.bat,
11539 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11540 earlier fix to add support for --cflags and --ldflags options
11541 that include quotes so that it works whether make uses cmd or
11544 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11546 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11547 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11549 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11550 a string. Handle both cases.
11551 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11552 (Fdbus_register_method): Use Qinvalid_function.
11554 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11556 * makefile.w32-in: Update dependencies.
11557 (LISP_H): Add inttypes.h and stdin.h.
11558 (PROCESS_H): Add unistd.h.
11560 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11562 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11563 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11565 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11567 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11569 * term.c (vfatal): Remove stray call to va_end.
11570 It's not needed and the C Standard doesn't allow it here anyway.
11572 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11573 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11575 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11578 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11580 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11582 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11584 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11586 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11588 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11589 * charset.c (Fdefine_charset_internal): Don't initialize
11590 charset.code_space[15]. The value was garbage, on hosts with
11591 32-bit int (Bug#8600).
11593 * lread.c (read_integer): Be more consistent with string-to-number.
11594 Use string_to_number to do the actual conversion; this avoids
11595 rounding errors and fixes some other screwups. Without this fix,
11596 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11597 (digit_to_number): Move earlier, for benefit of read_integer.
11598 Return -1 if the digit is out of range for the base, -2 if it is
11599 not a digit in any supported base. (Bug#8602)
11601 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11603 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11604 to match comment at start of function. This also removes a
11605 GCC warning about overflow in a 32+64-bit port.
11607 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11609 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11610 Reported by Stefan Monnier in
11611 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11612 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11613 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11615 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11616 (EMACS_UINTPTR): Likewise, with uintptr_t.
11618 * lisp.h: Prefer 64-bit EMACS_INT if available.
11619 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11620 on 32-bit hosts that have 64-bit int, so that they can access
11622 However, temporarily disable this change unless the temporary
11623 symbol WIDE_EMACS_INT is defined.
11625 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11627 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11628 This removes an assumption that EMACS_INT and long are the same
11629 width as pointers. The assumption is true for Emacs porting targets
11630 now, but we want to make other targets possible.
11631 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11632 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11633 In the rest of the code, change types of integers that hold casted
11634 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11635 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11636 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11637 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11638 No need to cast type when ORing.
11639 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11640 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11641 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11642 assume EMACS_INT is the same width as char *.
11643 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11644 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11645 Remove no-longer-needed casts.
11646 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11647 (xg_tool_bar_help_callback, xg_make_tool_item):
11648 Use EMACS_INTPTR to hold an integer
11649 that will be cast to void *; this can avoid a GCC warning
11650 if EMACS_INT is not the same width as void *.
11651 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11652 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11653 (current_message_1, set_message_1):
11654 Use a local to convert to proper width without a cast.
11655 * xmenu.c (dialog_selection_callback): Likewise.
11657 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11658 Also, don't assume VALBITS / RAND_BITS is less than 5,
11659 and don't rely on undefined behavior when shifting a 1 left into
11661 * lisp.h (get_random): Change signature to match.
11663 * lread.c (hash_string): Use size_t, not int, for hash computation.
11664 Normally we prefer signed values; but hashing is special, because
11665 it's better to use unsigned division on hash table sizes so that
11666 the remainder is nonnegative. Also, size_t is the natural width
11667 for hashing into memory. The previous code used 'int', which doesn't
11668 retain enough info to hash well into very large tables.
11669 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11671 * dbusbind.c: Don't possibly lose pointer info when converting.
11672 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11673 Use XPNTR rather than XHASH, so that the high-order bits of
11674 the pointer aren't lost when converting through void *.
11676 * eval.c (Fautoload): Don't double-shift a pointer.
11678 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11680 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11682 * gnutls.c (DEF_GNUTLS_FN):
11683 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11685 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11687 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11690 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11692 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11693 New version that can reserve upto 2GB of heap space.
11695 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11697 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11699 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11701 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11702 `gnutls_certificate_set_x509_key_file'.
11704 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11706 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11707 Update dependencies.
11709 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11711 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11712 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11713 Remove unused parameter `fildes'.
11714 * process.c (read_process_output, send_process): Don't pass it.
11716 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11718 Fix previous change: the library cache is defined in w32.c.
11719 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11720 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11722 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11724 Implement dynamic loading of GnuTLS on Windows.
11726 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11727 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11728 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11731 * gnutls.c (Qgnutls_dll): Define.
11732 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11733 (gnutls_*): Declare function pointers.
11734 (init_gnutls_functions): New function to initialize function pointers.
11735 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11736 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11737 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11738 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11739 (emacs_gnutls_write, emacs_gnutls_read)
11740 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11741 (Fgnutls_available_p): New function.
11742 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11743 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11744 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11746 * image.c: Include w32.h.
11747 (Vimage_type_cache): Delete.
11748 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11749 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11750 (w32_delayed_load): Move to w32.c.
11752 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11754 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11755 (w32_delayed_load): Move from image.c. When loading a library, record
11756 its filename in the :loaded-from property of the library id.
11757 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11758 Initialize and staticpro them.
11759 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11761 * process.c: Include lisp.h before w32.h, not after.
11762 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11763 instead of gnutls_record_check_pending.
11765 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11767 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11769 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11770 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists

11815 rather than `XVECTOR (FOO)->size'.
11817 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11818 inttypes.h, as a gnulib replacement is used if it not available in
11821 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11823 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

11831 space for up to 2 characters produced in a loop.
11832 (decode_coding_iso_2022): Abort if there isn't enough place in
11833 charbuf for the composition carryover bytes.
11835 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11837 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11838 aborting when %lld or %lll format is passed.
11839 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11840 %llo or %llx format is passed. (Bug#8545)
11842 * window.c (window_scroll_line_based): Use a marker instead of
11843 simple variables to record original value of point. (Bug#7952)
11845 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11846 produced by %s or %c overflows available buffer space. (Bug#8545)
11848 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11850 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11851 (SIZE_MAX): Move defn after all includes, as they might #define it.
11853 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11855 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11857 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11859 * keyboard.c (Qdelayed_warnings_hook): Define.
11860 (command_loop_1): Run `delayed-warnings-hook'
11861 if Vdelayed_warnings_list is non-nil.
11862 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11863 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11865 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11867 * doprnt.c (doprnt): Don't return value smaller than the buffer
11868 size if the message was truncated. (Bug#8545).
11870 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11872 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

11875 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11877 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11879 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11881 * makefile.w32-in: Update dependencies.
11883 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11885 Improve `doprnt' and its usage. (Bug#8545)
11886 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11887 `format_end'. Remove support for %l as a conversion specifier.
11888 Don't use xrealloc. Improve diagnostics when the %l size modifier
11889 is used. Update the commentary.
11891 * eval.c (verror): Simplify calculation of size_t.
11893 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11896 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11898 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11901 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11903 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11904 This makes this file independent of the recent pseudovector change.
11906 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11908 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11910 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11911 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11912 Remove unused local.
11913 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11915 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11916 GCC 4.6.0 optimizes based on type-based alias analysis.
11917 For example, if b is of type struct buffer * and v of type struct
11918 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11919 != &v->size, and therefore "v->size = 1; b->size = 2; return
11920 v->size;" must therefore return 1. This assumption is incorrect
11921 for Emacs, since it type-puns struct Lisp_Vector * with many other
11922 types. To fix this problem, this patch adds a new type struct
11923 vectorlike_header that documents the constraints on layout of vectors
11924 and pseudovectors, and helps optimizing compilers not get fooled
11925 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11926 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11927 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11929 (XSETPVECTYPE): Rewrite in terms of new macro.
11930 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11931 This is a bit clearer, and further avoids the possibility of
11932 undesirable aliasing.
11933 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11934 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11935 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11936 since Lisp_Subr is a special case (no "next" field).
11937 (ASIZE): Now uses header.size rather than size.
11938 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11939 to avoid the hassle of writing XVECTOR (foo)->header.size.
11940 (struct vectorlike_header): New type.
11941 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11942 object, to help avoid aliasing.
11943 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11944 (SUBRP): Likewise, since Lisp_Subr is a special case.
11945 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11946 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11947 (struct Lisp_Hash_Table): Combine first two members into a single
11948 struct vectorlike_header member. All uses of "size" and "next" members
11949 changed to be "header.size" and "header.next".
11950 * buffer.h (struct buffer): Likewise.
11951 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11952 * frame.h (struct frame): Likewise.
11953 * process.h (struct Lisp_Process): Likewise.
11954 * termhooks.h (struct terminal): Likewise.
11955 * window.c (struct save_window_data, struct saved_window): Likewise.
11956 * window.h (struct window): Likewise.
11957 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11958 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11959 * buffer.c (init_buffer_once): Likewise.
11960 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11962 * process.c (Fformat_network_address): Use local var for size,
11965 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11967 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11968 * data.c (atof): Remove decl; no longer used or needed.
11969 (digit_to_number): Move to lread.c.
11970 (Fstring_to_number): Use new string_to_number function, to be
11971 consistent with how the Lisp reader treats infinities and NaNs.
11972 Do not assume that floating-point numbers represent EMACS_INT
11973 without losing information; this is not true on most 64-bit hosts.
11974 Avoid double-rounding errors, by insisting on integers when
11975 parsing non-base-10 numbers, as the documentation specifies.
11976 * lisp.h (string_to_number): New decl, replacing ...
11977 (isfloat_string): Remove.
11978 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11979 (read1): Do not accept +. and -. as integers; this
11980 appears to have been a coding error. Similarly, do not accept
11981 strings like +-1e0 as floating point numbers. Do not report
11982 overflow for integer overflows unless the base is not 10 which
11983 means we have no simple and reliable way to continue.
11984 Break out the floating-point parsing into a new
11985 function string_to_number, so that Fstring_to_number parses
11986 floating point numbers consistently with the Lisp reader.
11987 (digit_to_number): Move here from data.c. Make it static inline.
11988 (E_CHAR, EXP_INT): Remove, replacing with ...
11989 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11990 (string_to_number): New function, replacing isfloat_string.
11991 This function checks for valid syntax and produces the resulting
11992 Lisp float number too. Rework it so that string-to-number
11993 no longer mishandles examples like "1.0e+". Use strtoumax,
11994 so that overflow for non-base-10 numbers is reported only when
11995 there's no portable and simple way to convert to floating point.
11997 * textprop.c (set_text_properties_1): Rewrite for clarity,
11998 and to avoid GCC warning about integer overflow.
12000 * intervals.h (struct interval): Use EMACS_INT for members
12001 where EMACS_UINT might cause problems. See
12002 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12003 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12004 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12006 (offset_intervals): Tell GCC not to worry about length overflow
12007 when negating a negative length.
12009 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12010 (overrun_check_free): Likewise.
12012 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12013 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12016 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12017 (gnutls_make_error): Rename local to avoid shadowing.
12018 (gnutls_emacs_global_deinit): ifdef out; not used.
12019 (Fgnutls_boot): Use const for pointer to readonly storage.
12020 Comment out unused local. Fix pointer signedness problems.
12022 * lread.c (openp): Don't stuff size_t into an 'int'.
12023 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12024 about possible signed overflow.
12026 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12027 (GDK_KEY_g): Don't define if already defined.
12028 (xg_prepare_tooltip): Avoid pointer signedness problem.
12029 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12031 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12032 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12034 * xfns.c (Fx_window_property): Simplify a bit,
12035 to make a bit faster and to avoid GCC 4.6.0 warning.
12036 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12038 * fns.c (internal_equal): Don't assume size_t fits in int.
12040 * alloc.c (compact_small_strings): Tighten assertion a little.
12042 Replace pEd with more-general pI, and fix some printf arg casts.
12043 * lisp.h (pI): New macro, generalizing old pEd macro to other
12044 conversion specifiers. For example, use "...%"pI"d..." rather
12045 than "...%"pEd"...".
12046 (pEd): Remove. All uses replaced with similar uses of pI.
12047 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12048 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12049 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12050 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12051 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12052 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12053 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12055 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12056 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12057 * print.c (safe_debug_print, print_object): Likewise.
12058 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12060 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12061 avoiding the 0 flag, which is not portable.
12062 * process.c (Fmake_network_process): Use pI to avoid cast.
12063 * region-cache.c (pp_cache): Likewise.
12064 * xdisp.c (decode_mode_spec): Likewise.
12065 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12066 behavior on 64-bit hosts with printf arg.
12067 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12068 (x_stop_queuing_selection_requests): Likewise.
12069 (x_get_window_property): Don't truncate byte count to an 'int'
12072 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12073 here, since it parses constructs like leading '-' and spaces,
12074 which are not wanted; and it overflows with large numbers.
12075 Instead, simply match F[0-9]+, which is what is wanted anyway.
12077 * alloc.c: Remove unportable assumptions about struct layout.
12078 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12079 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12080 (allocate_vectorlike, make_pure_vector): Use the new macros,
12081 plus offsetof, to remove unportable assumptions about struct layout.
12082 These assumptions hold on all porting targets that I know of, but
12083 they are not guaranteed, they're easy to remove, and removing them
12084 makes further changes easier.
12086 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12087 This doesn't fix a bug but makes the code clearer.
12088 (string_overrun_cookie): Now const. Use initializers that
12089 don't formally overflow signed char, to avoid warnings.
12090 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12091 can cause Emacs to crash when string overrun checking is enabled.
12092 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12093 multiple of sizeof (EMACS_INT); it need not be, if
12094 alignof(EMACS_INT) < sizeof (EMACS_INT).
12095 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12097 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12101 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12103 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12104 supposed to be handshaking. (Bug#8556)
12105 Reported by Paul Eggert <eggert@cs.ucla.edu>.

12112 (handle_user_signal): Break into debugger when debug-on-event
12113 matches the current signal symbol.
12115 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12117 * alloc.c (check_sblock, check_string_bytes)
12118 (check_string_free_list): Convert to standard C.
12120 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12122 * w32.c (emacs_gnutls_push): Fix typo.
12124 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12126 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12127 "cast to pointer from integer of different size".
12129 Improve doprnt and its use in verror. (Bug#8545)
12130 * doprnt.c (doprnt): Document the set of format control sequences
12131 supported by the function. Use SAFE_ALLOCA instead of always
12134 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12135 is one byte too soon. Don't use xrealloc; instead xfree and
12138 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12140 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12143 * gnutls.c: Renamed global_initialized to
12144 gnutls_global_initialized. Added internals for the
12145 :verify-hostname-error, :verify-error, and :verify-flags
12146 parameters of `gnutls-boot' and documented those parameters in the
12147 docstring. Start callback support.
12148 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12149 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12150 on error. Return error code.
12151 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12152 (emacs_gnutls_read): Likewise.
12153 (Fgnutls_boot): Return handshake error code.
12154 (emacs_gnutls_handle_error): New function.
12155 (wsaerror_to_errno): Likewise.
12157 * w32.h (emacs_gnutls_pull): Add prototype.
12158 (emacs_gnutls_push): Likewise.
12160 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12161 (emacs_gnutls_push): Likewise.
12163 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
12165 * process.c (wait_reading_process_output): Check if GnuTLS
12166 buffered some data internally if no FDs are set for TLS
12169 * makefile.w32-in (OBJ2): Add gnutls.$(O).
12170 (LIBS): Link to USER_LIBS.

12175 * xdisp.c (handle_single_display_spec): Rename the
12176 display_replaced_before_p argument into display_replaced_p, to
12177 make it consistent with the commentary. Fix typos in the
12180 * textprop.c (syms_of_textprop): Remove dead code.
12181 (copy_text_properties): Delete obsolete commentary about an
12182 interface that was deleted long ago. Fix typos in the description

12186 to changes in oldXMenu/XMenu.h from 2011-04-16.
12187 <menu_help_message, prev_menu_help_message>: Constify.
12188 (IT_menu_make_room): menu->help_text is now `const char **';
12191 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
12192 to changes in oldXMenu/XMenu.h from 2011-04-16.
12193 (struct XMenu): Declare `help_text' `const char **'.

12204 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
12206 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
12209 * makefile.w32-in (globals.h): Add a dummy recipe, to make any

12455 ns_descriptor_to_entity that were caused by using free to
12456 deallocate memory blocks that were allocated by xmalloc (via
12457 xstrdup). This caused Emacs to crash when compiled with

12477 (emacs_read, emacs_write): Use it.
12478 * process.c (send_process): Adjust to the new signatures of
12479 emacs_write and emacs_gnutls_write. Do not attempt to store

12678 * xfaces.c (face_at_string_position):
12679 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
12680 since 0 is always ASCII.
12682 * fns.c (weak_hash_tables): Now static.
12684 * fileio.c: Make symbols static if they're not exported.
12685 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

12699 * lisp.h (fatal_error_signal_hook): Remove decl.
12700 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

12703 * editfns.c, lisp.h (get_operating_system_release): Remove.
12704 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
12705 worth the hassle of breaking this out.
12707 * xterm.c: Make symbols static if they're not exported.
12708 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
12709 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

12809 * lisp.h: Remove these decls.
12811 * buffer.c (buffer_count): Remove unused var.
12813 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

12820 * atimer.h (run_all_atimers): Remove; not exported.
12822 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12823 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12824 was inaccessible from Lisp.
12825 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12826 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12828 alloc.c: Import and export fewer symbols, and remove unused items.
12829 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12831 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12832 it's not optimized away by whole-program optimization.

12835 Declare only if BYTE_MARK_STACK.

12844 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12845 (mark_backtrace): Define only if BYTE_MARK_STACK.
12846 * xdisp.c (message_enable_multibyte): Now static.
12848 Declare Lisp_Object Q* variables to be 'static' if not exported.
12849 This makes it easier for human readers (and static analyzers)
12850 to see whether these variables are used from other modules.
12851 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12852 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

12861 Remove decls of unexported vars.
12862 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12864 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12866 Make Emacs functions such as Fatom 'static' by default.
12867 This makes it easier for human readers (and static analyzers)
12868 to see whether these functions can be called from other modules.
12869 DEFUN now defines a static function. To make the function external
12870 so that it can be used in other C modules, use the new macro DEFUE.
12871 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12872 (Finit_image_library):
12873 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12874 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12875 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12876 Remove decls, since these functions are now static.
12877 (Funintern, Fget_internal_run_time): New decls, since these functions
12878 were already external.
12880 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12881 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12887 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12888 Mark functions with DEFUE instead of DEFUN,
12889 if they are used in other modules.
12890 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12891 decls for now-static functions.
12892 * buffer.h (Fdelete_overlay): Remove decl.
12893 * callproc.c (Fgetenv_internal): Mark as internal.

12902 * image.c (Finit_image_library): New forward static decl.
12903 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12904 * intervals.h (Fprevious_property_change):
12905 (Fremove_list_of_text_properties): Remove decls.
12906 * keyboard.c (Fthis_command_keys): Remove decl.
12907 (Fcommand_execute): New forward static decl.

12928 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12930 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12931 when at ZV. (Bug#8487)
12933 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12935 * charset.c (Fclear_charset_maps): Use xfree instead of free.

12938 * sound.c (sound_cleanup, alsa_close): Likewise.
12939 * termcap.c (tgetent): Likewise.

12941 * xsettings.c (read_and_apply_settings): Likewise.
12943 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12944 (overrun_check_free): Protoize.
12946 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12948 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12949 since callers should never pass a negative size.
12950 Change the signature to match that of plain 'read' and 'write'; see
12951 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12952 * lisp.h: Update prototypes of emacs_write and emacs_read.
12954 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12956 * xdisp.c (redisplay_window): Don't try to determine the character
12957 position of the scroll margin if the window start point w->startp
12958 is outside the buffer's accessible region. (Bug#8468)
12960 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12962 Fix write-region and its subroutines for buffers > 2GB.
12963 * fileio.c (a_write, e_write): Modify declaration of arguments and
12964 local variables to support buffers larger than 2GB.
12965 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12967 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12968 argument, local variables, and return value.
12970 * lisp.h: Update prototypes of emacs_write and emacs_read.
12972 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12974 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12976 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12978 Fix more problems found by GCC 4.6.0's static checks.
12980 * xdisp.c (vmessage): Use a better test for character truncation.
12982 * charset.c (load_charset_map): <, not <=, for optimization,
12983 and to avoid potential problems with integer overflow.
12984 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12985 * casetab.c (set_identity, shuffle): Likewise.
12986 * editfns.c (Fformat): Likewise.
12987 * syntax.c (skip_chars): Likewise.
12989 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12990 This also lets GCC 4.6.0 generate slightly better loop code.
12992 * callint.c (Fcall_interactively): <, not <=, for optimization.
12993 (Fcall_interactively): Count the number of arguments produced,
12994 not the number of arguments given. This is simpler and lets GCC
12995 4.6.0 generate slightly better code.
12997 * ftfont.c: Distingish more carefully between FcChar8 and char.
12998 The previous code passed unsigned char * to a functions like
12999 strlen and xstrcasecmp that expect char *, which does not
13000 conform to the C standard.
13001 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13002 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13003 char * when the C standard requires it.
13005 * keyboard.c (read_char): Remove unused var.
13007 * eval.c: Port to Windows vsnprintf (Bug#8435).
13008 Include <limits.h>.
13009 (SIZE_MAX): Define if the headers do not.
13010 (verror): Do not give up if vsnprintf returns a negative count.
13011 Instead, grow the buffer. This ports to Windows vsnprintf, which
13012 does not conform to C99. Problem reported by Eli Zaretskii.
13013 Also, simplify the allocation scheme, by avoiding the need for
13014 calling realloc, and removing the ALLOCATED variable.
13016 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13018 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13019 But keep the doprint source code for now, as we might revamp it
13020 and use it again (Bug#8435).
13021 * lisp.h (doprnt): Remove.
13022 * Makefile.in (base_obj): Remove doprnt.o.
13023 * deps.mk (doprnt.o): Remove.
13025 error: Print 32- and 64-bit integers portably (Bug#8435).
13026 Without this change, on typical 64-bit hosts error ("...%d...", N)
13027 was used to print both 32- and 64-bit integers N, which relied on
13028 undefined behavior.
13029 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13030 * lisp.h (error, verror): Mark as printf-like functions.
13031 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13032 Report overflow in size calculations when allocating printf buffer.
13033 Do not truncate output string at its first null byte.
13034 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13035 Truncate the output at a character boundary, since vsnprintf does not
13037 * charset.c (check_iso_charset_parameter): Convert internal
13038 character to string before calling 'error', since %c now has the
13040 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13041 overflow when computing char to be passed to 'error'. Do not
13042 pass Lisp_Object to 'error'; pass the integer instead.
13043 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13044 formatted with plain %d.
13046 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13048 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13050 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13052 * xterm.c (x_catch_errors): Remove duplicate declaration.
13054 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13056 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13058 2011-04-10 Jim Meyering <meyering@redhat.com>
13060 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13061 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13062 return ssize_t not "int", and use size_t as the buffer length.
13063 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13064 * gnutls.h: Update declarations.
13065 * process.c (read_process_output): Use ssize_t, to match.
13066 (send_process): Likewise.
13068 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13070 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13072 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13074 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13075 Use unsigned char, to match FcChar8 type definition.
13077 * xterm.c (handle_one_xevent):
13078 * xmenu.c (create_and_show_popup_menu):
13079 * xselect.c (x_decline_selection_request)
13080 (x_reply_selection_request): Avoid type-punned deref of X events.
13082 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13084 Fix some uses of `int' instead of EMACS_INT.

13091 * xdisp.c (display_count_lines): 3rd argument and return value now
13092 EMACS_INT. All callers changed.

13138 instead of using internal_with_output_to_temp_buffer.
13139 (Qhelp_form_show): New var.
13140 (syms_of_keyboard): Use DEFSYM macro.
13142 * print.c (internal_with_output_to_temp_buffer): Function deleted.

13165 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13167 * xdisp.c (vmessage): Mark as a printf-like function.
13169 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13176 to system-supplied API.
13178 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13180 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13181 This avoids several warnings with gcc -Wstrict-overflow.
13182 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13183 directly, rather than having caller test rule sign. This avoids
13184 some unnecessary tests.
13185 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13186 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13187 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13189 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13190 (xfont_open): Avoid unnecessary tests.
13192 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13194 * composite.h, composite.c (composition_gstring_put_cache):
13195 Use EMACS_INT, not int, for length.
13197 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13198 breaking out part of COMPOSITION_DECODE_RULE.
13199 (COMPOSITION_DECODE_RULE): Use it.
13200 * composite.c (get_composition_id): Remove unused local vars,
13201 by using the new macro.
13203 * textprop.c (set_text_properties_1): Change while to do-while,
13204 since the condition is always true at first.
13206 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13207 (interval_deletion_adjustment): Return unsigned value.
13210 * process.c (list_processes_1, create_pty, read_process_output):
13211 (exec_sentinel): Remove vars that were set but not used.
13212 (create_pty): Remove unnecessary "volatile"s.
13213 (Fnetwork_interface_info): Avoid possibility of int overflow.

13226 * print.c (print_error_message): Avoid int overflow.
13228 * font.c (font_list_entities): Redo for clarity,
13229 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13231 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13232 (font_score): Avoid potential overflow in diff calculation.
13234 * fns.c (substring_both): Remove var that is set but not used.
13235 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13237 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13239 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13240 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13241 can always succeed if overflow has undefined behavior.
13243 * search.c (boyer_moore, wordify): Remove vars set but not used.
13244 (wordify): Omit three unnecessary tests.
13246 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13247 All callers changed. This avoids the need for an unused var.

13255 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13256 (Finsert_file_contents): Remove unnecessary code checking fd.
13258 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13259 Check for integer overflow on size calculations.
13261 * buffer.c (Fprevious_overlay_change): Remove var that is set
13264 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13265 Remove vars that are set but not used.
13266 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13267 (timer_check_2): Mark vars as initialized.
13269 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13271 * image.c (lookup_image): Remove var that is set but not used.
13272 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13274 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13275 that are set but not used.
13277 * xfns.c (make_invisible_cursor): Don't return garbage
13278 if XCreateBitmapFromData fails (Bug#8410).
13280 * xselect.c (x_get_local_selection, x_handle_property_notify):
13281 Remove vars that are set but not used.
13283 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13284 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13286 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13287 Remove var that is set but not used.
13288 (scroll_bar_windows_size): Now size_t, not int.
13289 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13290 Check for overflow.
13292 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13293 (map_tty_color) [!defined MSDOS]: Likewise.
13295 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13297 * coding.c: Remove vars that are set but not used.
13298 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13299 All callers changed.
13300 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13301 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13302 (decode_coding_charset): Remove vars that are set but not used.
13304 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13305 that is set but not used.
13307 * print.c (print_object): Remove var that is set but not used.
13309 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13310 The gnulib version avoids calling malloc in the usual case,
13311 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13312 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13313 * filelock.c (current_lock_owner): Likewise.
13314 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13315 * sysdep.c: Include allocator.h, careadlinkat.h.
13316 (emacs_no_realloc_allocator): New static constant.
13317 (emacs_readlink): New function.
13318 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13319 ../lib/careadlinkat.h.
13321 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13323 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13324 first non-nil return value).
13326 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13328 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13329 if not defined (Bug#8403).
13331 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13333 * xdisp.c (display_count_lines): Remove parameter `start',
13334 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13335 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13336 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13338 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13339 and thereabouts. All callers changed.
13340 (get_per_char_metric): Remove parameter `f', unused since
13341 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13343 2011-04-02 Jim Meyering <meyering@redhat.com>
13345 do not dereference NULL upon failed strdup
13346 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13347 (ns_get_family): Likewise.
13349 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13351 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13353 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13355 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13358 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13360 Add lexical binding.
13362 * window.c (Ftemp_output_buffer_show): New fun.
13363 (Fsave_window_excursion):
13364 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13366 * lread.c (lisp_file_lexically_bound_p): New function.
13367 (Fload): Bind Qlexical_binding.
13368 (readevalloop): Remove `evalfun' arg.
13369 Bind Qinternal_interpreter_environment.
13370 (Feval_buffer): Bind Qlexical_binding.
13371 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13373 (syms_of_lread): Declare `lexical-binding'.
13375 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13377 * keyboard.c (eval_dyn): New fun.
13378 (menu_item_eval_property): Use it.
13380 * image.c (parse_image_spec): Use Ffunctionp.
13382 * fns.c (concat, mapcar1): Accept byte-code-functions.
13384 * eval.c (Fsetq): Handle lexical vars.
13385 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13386 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13387 (FletX, Flet): Obey lexical binding.
13388 (Fcommandp): Handle closures.
13389 (Feval): New `lexical' arg.
13390 (eval_sub): New function extracted from Feval. Use it almost
13391 everywhere where Feval was used. Look up vars in lexical env.
13393 (Ffunctionp): Move from subr.el.
13394 (Ffuncall): Handle closures.
13395 (apply_lambda): Remove `eval_flags'.
13396 (funcall_lambda): Handle closures and new byte-code-functions.
13397 (Fspecial_variable_p): New function.
13398 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13399 but without exporting it to Lisp.
13401 * doc.c (Fdocumentation, store_function_docstring):
13402 * data.c (Finteractive_form): Handle closures.
13404 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13407 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13409 (exec_byte_code): New function extracted from Fbyte_code to handle new
13410 calling convention for byte-code-functions. Add new byte-codes.
13412 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13414 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13416 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13418 * xdisp.c (redisplay_internal): Fix prototype.
13420 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13422 * xdisp.c (SCROLL_LIMIT): New macro.
13423 (try_scrolling): Use it when setting scroll_limit.
13424 Limit scrolling to 100 screen lines.
13425 (redisplay_window): Even when falling back on "recentering",
13426 position point in the window according to scroll-conservatively,
13427 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13429 (try_scrolling): When point is above the window, allow searching
13430 as far as scroll_max, or one screenful, to compute vertical
13431 distance from PT to the scroll margin position. This prevents
13432 try_scrolling from unnecessarily failing when
13433 scroll-conservatively is set to a value slightly larger than the
13434 window height. Clean up the case of PT below the margin at bottom
13435 of window: scroll_max can no longer be INT_MAX. When aggressive
13436 scrolling is in use, don't let point enter the opposite scroll
13437 margin as result of the scroll.
13438 (syms_of_xdisp) <scroll-conservatively>: Document the
13439 threshold of 100 lines for never-recentering scrolling.
13441 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13443 * dispextern.h (move_it_by_lines):
13444 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13445 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13446 (message_log_check_duplicate): Remove parameters `prev_bol' and
13447 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13448 (redisplay_internal): Remove parameter `preserve_echo_area',
13449 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13451 * indent.c (Fvertical_motion):
13452 * window.c (window_scroll_pixel_based, Frecenter):
13453 Don't pass `need_y_p' to `move_it_by_lines'.
13455 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13457 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13458 steal a few bits to be more compact.
13459 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13460 Remove unneeded casts.
13462 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13464 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13466 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13467 binding" message (bug#7967).
13469 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13471 Fix more problems found by GCC 4.6.0's static checks.
13473 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13474 Remove unused local var.
13476 * editfns.c (Fmessage_box): Remove unused local var.
13478 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13479 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13480 Omit unused local vars.
13481 * window.c (shrink_windows): Omit unused local var.
13482 * menu.c (digest_single_submenu): Omit unused local var.
13483 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13484 Omit unused local var.
13486 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13487 Don't assume string length fits in int.
13488 (keyremap_step, read_key_sequence): Use size_t for sizes.
13489 (read_key_sequence): Don't check last_real_key_start redundantly.
13491 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13492 instead of alloca (Bug#8344).
13494 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13495 (Fbacktrace_frame): Don't assume nframes fits in int.
13497 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13499 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13502 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13504 * cm.c (calccost): Turn while-do into do-while, for clarity.
13506 * keyboard.c (syms_of_keyboard): Use the same style as later
13507 in this function when indexing through an array. This also
13508 works around GCC bug 48267.
13510 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13512 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13514 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13515 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13517 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13518 This avoids undefined behavior on integer overflow, and is a bit
13519 more convenient anyway since it is compared to a size_t variable.
13521 Variadic C functions now count arguments with size_t, not int.
13522 This avoids an unnecessary limitation on 64-bit machines, which
13523 caused (substring ...) to crash on large vectors (Bug#8344).
13524 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13525 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13526 All variadic functions and their callers changed accordingly.

13533 * fns.c (concat): Likewise.
13534 * frame.c (x_set_frame_parameters): Likewise.
13535 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13536 0 if not found, not -1. All callers changed.
13538 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13539 (stack_copy_size): Now size_t, not int.
13540 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

13751 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13753 Fix more problems found by GCC 4.5.2's static checks.
13755 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13756 the first time through the loop, since we know p0 < p1 then.
13757 This also avoids a gcc -Wstrict-overflow warning.
13759 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13760 leading to a memory leak, possible in functions like
13761 load_charset_map_from_file that can allocate an unbounded number
13762 of objects (Bug#8318).
13764 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13765 that could (at least in theory) be that large.
13767 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13768 This is less likely to overflow, and avoids undefined behavior if
13769 overflow does occur. All callers changed. Use strtoul to scan
13770 for the unsigned long integer.

13787 * process.c (Fmake_network_process): Use socklen_t, not int,
13788 where POSIX says socklen_t is required in portable programs.
13789 This fixes a porting bug on hosts like 64-bit HP-UX, where
13790 socklen_t is wider than int (Bug#8277).
13791 (Fmake_network_process, server_accept_connection):
13792 (wait_reading_process_output, read_process_output):
13795 * process.c: Rename or move locals to avoid shadowing.

13807 Include tparam.h instead, since it declares them.
13808 * cm.h (PC): Remove extern decl; tparam.h now does this.
13809 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13810 * terminfo.c: Include tparam.h, to check interfaces.
13811 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13812 (tparam): Adjust signature to match interface in tparam.h;
13813 this removes some undefined behavior. Check that outstring and len
13814 are zero, which they always are with Emacs.
13815 * tparam.h (PC, BC, UP): New extern decls.
13817 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13818 (xftfont_open): Rename locals to avoid shadowing.

13836 (composition_update_it): Mark var as initialized.
13837 (find_automatic_composition): Mark vars as initialized,
13838 with a FIXME (Bug#8290).

13858 (alsa_choose_format): Remove unused local var.
13859 (wav_play): Initialize a variable to 0, to prevent undefined
13860 behavior (Bug#8278).
13862 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13864 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13866 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13867 clobbering (Bug#8298).
13868 * sysdep.c (sys_subshell): Likewise.
13869 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13871 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13872 This should get cleaned up, so that child_setup has the
13873 same signature on all platforms.
13875 * callproc.c (call_process_cleanup): Now static.
13876 (relocate_fd): Rename locals to avoid shadowing.
13878 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13880 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13881 not to be necessary, and produces flickering.
13883 2011-03-20 Glenn Morris <rgm@gnu.org>
13885 * config.in: Remove file.
13887 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

13932 Define only if needed.
13934 * unexelf.c (unexec): Name an expression,
13935 to avoid gcc -Wbad-function-cast warning.
13936 Use a different way to cause a compilation error if anyone uses
13937 n rather than nn, a way that does not involve shadowing.
13938 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13940 * deps.mk (unexalpha.o): Remove; unused.

13988 * alloc.c (mark_backtrace): Move decl from here ...
13989 * lisp.h: ... to here, so that it can be checked.
13991 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
13992 (Fdefvar): Rewrite so as not to use empty "else".
13993 (lisp_indirect_variable): Name an expression,
13994 to avoid gcc -Wbad-function-cast warning.
13995 (Fdefvar): Rename locals to avoid shadowing.
13997 * callint.c (quotify_arg, quotify_args): Now static.
13998 (Fcall_interactively): Rename locals to avoid shadowing.

14003 * process.c (get_operating_system_release): Move decl to lisp.h.
14004 * xrdb.c (get_system_name): Likewise.
14005 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14006 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14007 some of which prompt warnings from gcc -Wbad-function-cast.
14008 (Fformat_time_string, Fencode_time, Finsert_char):
14009 (Ftranslate_region_internal, Fformat):
14010 Rename or remove local vars to avoid shadowing.

14036 (GC_STRING_CHARS): Remove; not used.
14037 (Fmemory_limit): Cast sbrk's returned value to char *.
14039 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14040 avoids undefined behavior in theory.
14042 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14044 Use functions, not macros, for up- and down-casing (Bug#8254).
14045 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14046 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14047 to use the following functions instead of these macros.
14048 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14049 EMACS_INT, since callers assume the returned value fits in int.
14050 (upcase1): Likewise, for UPCASE_TABLE.
14051 (uppercasep, lowercasep, upcase): New static inline functions.
14052 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14062 (regex_compile, re_match_2_internal): Mark locals as initialized.
14063 (RETALLOC_IF): Define only if needed.
14064 (WORDCHAR_P): Likewise. This one is never needed, but is used
14065 only in a comment talking about a compiler bug, so put inside
14066 the #if 0 of that comment.
14067 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14068 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14094 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14095 New macros, so that the caller can use some names other than
14096 gcpro1, gcpro2, etc.
14097 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14099 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14100 argument, for consistency with GCPRO2_VAR, etc: it is now the
14101 prefix of the variable, not the variable itself. All uses
14103 * dired.c (directory_files_internal, file_name_completion):
14104 Rename locals to avoid shadowing.
14106 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14107 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14108 dired.c's scmp function, had undefined behavior.
14109 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14110 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14111 * buffer.h: ... to here, because these macros use current_buffer,
14112 and the new implementation with inline functions needs to have
14113 current_buffer in scope now, rather than later when the macros
14115 (downcase, upcase1): New static inline functions.
14116 (DOWNCASE, UPCASE1): Reimplement using these functions.
14117 This avoids undefined behavior in expressions like
14118 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14119 from race conditions in accessing the global variables
14120 case_temp1 and case_temp2.
14121 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14122 * lisp.h (case_temp1, case_temp2): Remove their decls.
14123 * character.h (ASCII_CHAR_P): Move from here ...
14124 * lisp.h: ... to here, so that the inline functions mentioned
14125 above can use them.
14127 * dired.c (directory_files_internal_unwind): Now static.
14129 * fileio.c (file_name_as_directory, directory_file_name):
14130 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14132 (file_name_as_directory): Use const pointers when appropriate.
14133 (Fexpand_file_name): Likewise. In particular, newdir might
14134 point at constant storage, so make it a const pointer.
14135 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14136 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14138 (Fset_file_times, Finsert_file_contents, auto_save_error):

14143 to avoid shadowing.
14145 * marker.c (bytepos_to_charpos): Remove; unused.
14147 * lisp.h (verify_bytepos, count_markers): New decls,
14148 so that gcc does not warn that these functions aren't declared.
14150 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14151 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14152 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14153 (copy_text): Remove unused local var.
14155 * filelock.c (within_one_second): Now static.
14156 (lock_file_1): Rename local to avoid shadowing.
14158 * buffer.c (fix_overlays_before): Mark locals as initialized.
14159 (fix_start_end_in_overlays): Likewise. This function should be
14160 simplified by using pointers-to-pointers, but that's a different
14162 (switch_to_buffer_1): Now static.
14163 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14164 (report_overlay_modification): Rename locals to avoid shadowing.

14167 Fix pointer signedness issue.
14168 (sys_subshell): Mark local as volatile if checking for lint,
14169 to suppress a gcc -Wclobbered warning that does not seem to be right.
14170 (MAXPATHLEN): Define only if needed.
14172 * process.c (serial_open, serial_configure): Move decls from here ...
14173 * systty.h: ... to here, so that they can be checked.
14175 * fns.c (get_random, seed_random): Move extern decls from here ...
14176 * lisp.h: ... to here, so that they can be checked.
14178 * sysdep.c (reset_io): Now static.

14187 (describe_map_tree):
14188 Rename locals to avoid shadowing.
14190 * keyboard.c: Declare functions static if they are not used elsewhere.

14337 For example, without this patch (encode-time 0 0 0 1 1
14338 1152921504606846976) returns the obviously-bogus value (-948597
14339 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
14340 reports time overflow. See
