481 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
483 Fast save_excursion_save and save_excursion_restore.
484 * lisp.h (struct Lisp_Excursion): New data type.
485 (PVEC_EXCURSION): New pseudovector type.

501 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
502 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
503 emacs.c, as this is a more-suitable home. Had this been done earlier
504 the fix for 12036 would have avoided some of the problems noted in
505 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
506 would have been more obvious.
507 * emacs.c: Do not include <verify.h>; no longer needed.
508 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
509 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
510 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
511 Remove; now done in lisp.h.

514 (DATA_SEG_BITS): Use it.
515 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
516 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
517 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
518 not be usable in #if. This simplifies things.
520 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
522 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
524 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

527 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
528 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
529 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
530 Adjust to changes in lisp.h and emacs.c, by using
531 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
532 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
533 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
534 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
535 instead of gdb_valbits.
536 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
537 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
538 instead of gdb_array_mark_flag.
539 (xboolvector): Get size from $->size, not $->header.size.
540 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
541 (xreload, hook-run, hookpost-run): Remove.
542 * emacs.c: Include <verify.h>.
543 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
544 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
546 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
547 (gdb_USE_LSB_TAG): New enum constants.
548 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
549 Also define these as enum constants, so they're visible to GDB.
550 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
551 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
552 as constants, so they're visible to GDB.
553 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
554 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
555 Now enum constants, not macros, so they're visible to GDB.
556 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
557 more convenient now. All uses changed.
558 (VALMASK) [USE_LSB_TAG]: Also define in this case.
559 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

569 add argument, tune behavior, and adjust all callers.
571 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
573 Use typedef for EMACS_INT, EMACS_UINT.
574 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
575 than macros. This simplifies debugging in the usual case, since
576 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
577 and it allows expressions involving EMACS_INT casts.
578 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
580 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

594 buffer is definitely dead. This should really fix an issue reported
595 by Christoph Scholtes again. (Bug#12007).
596 (init_buffer_once): Initialize indirection counters of
597 buffer_defaults and buffer_local_symbols (for sanity and safety).
599 2012-07-24 Eli Zaretskii <eliz@gnu.org>
601 * xdisp.c (init_iterator): Don't compute dimensions of truncation
602 and continuation glyphs on tooltip frames, leave them at zero.
603 Avoids continued lines in tooltips. (Bug#11832)
605 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

632 Swap buffer text indirection counters in Fbuffer_swap_text.
633 * buffer.c (Fbuffer_swap_text): Swap indirections too.
634 This avoids crash reported by Christoph Scholtes at
635 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
637 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
639 * nsmenu.m (Popdown_data): New struct.

662 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
664 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
665 as it's limited by the amount of memory, not by INT_MAX.
667 2012-07-21 Eli Zaretskii <eliz@gnu.org>
669 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
670 in special-event-map. See the discussion at

751 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
752 'for_each_per_buffer_object_at'.

1399 * systime.h: Include <sys/time.h> on all hosts, not just if
1400 WINDOWSNT, since 'struct timeval' is needed in general.
1401 (EMACS_TIME): Now a typedef, not a macro.
1402 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1404 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

1407 (EMACS_TIME_LE): Now functions, not macros.
1408 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1409 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1410 which are not functions. All uses rewritten to use:
1411 (make_emacs_time): New function.
1412 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1413 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1414 not functions. All uses rewritten to use the following, respectively:
1415 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1416 (add_emacs_time, sub_emacs_time): New functions.
1417 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1418 * fileio.c (Fcopy_file):
1419 * xterm.c (XTflash): Get the current time closer to when it's used.

1437 Prefer memcmp to strncmp when either will do.
1438 * nsterm.m: Include <ftoastr.h>.
1440 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1441 Prefer snprintf to strncpy.
1442 * nsterm.m (ns_term_init):
1443 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1444 * nsterm.m (ns_term_init):
1445 Avoid the need for strncpy, by using build_string or
1446 make_unibyte_string directly. Use dtoastr, not snprintf.
1447 * process.c (Fmake_network_process): Diagnose service names that
1448 are too long, rather than silently truncating them or creating
1449 non-null-terminated names.
1450 (Fnetwork_interface_info): Likewise, for interface names.
1451 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1452 Prefer sprintf to strncat.
1453 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1454 Prefer vsnprintf to vsprintf + strncpy.
1456 2012-07-10 Glenn Morris <rgm@gnu.org>
1458 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1459 Clarify fallback case.
1461 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1463 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1464 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1465 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1466 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1467 where argument type is known to be a Lisp_Cons.

1477 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1479 Optimize pure C strings initialization.
1480 * lisp.h (make_pure_string): Fix prototype.
1481 (build_pure_c_string): New function, defined as static inline. This
1482 provides a better opportunity to optimize away calls to strlen when
1483 the function is called with compile-time constant argument.
1484 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1485 argument, adjust users accordingly. Use build_pure_c_string where
1487 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1488 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1489 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1491 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1493 Avoid calls to strlen in miscellaneous functions.
1494 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1495 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1496 * lread.c (openp): Likewise.
1498 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1500 Avoid calls to strlen in path processing functions.
1501 * fileio.c (file_name_as_directory): Add comment. Change to add
1502 srclen argument and return the length of result. Adjust users
1504 (directory_file_name): Fix comment. Change to add srclen argument,
1505 swap 1st and 2nd arguments to obey the common convention. Adjust
1507 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1509 2012-07-10 Glenn Morris <rgm@gnu.org>
1511 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1512 Move PENDING_OUTPUT_COUNT definition to configure.
1514 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1515 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1516 * s/gnu.h (DATA_START): Move definitions to configure.
1518 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1519 We include usg5-4-common.h, which defines them both.
1521 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1522 O_RDONLY already includes it).
1524 Stop ns builds setting the EMACSLOADPATH environment variable.
1525 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1526 Now it does not set EMACSLOADPATH, just returns the load-path string.
1527 * nsterm.h: Update accordingly.
1528 * lread.c [HAVE_NS]: Include nsterm.h.
1529 (init_lread) [HAVE_NS]: Use ns_load_path.
1530 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1532 2012-07-09 Glenn Morris <rgm@gnu.org>
1534 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1535 since the included bsd-common.h does so.
1537 Stop ns builds setting the EMACSPATH environment variable.
1538 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1539 (ns_init_paths): Do not set EMACSPATH.
1540 * nsterm.h (ns_exec_path): Add it.
1541 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1544 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1546 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1548 * process.c (wait_reading_process_output): 'waitchannels' was unset
1549 when read_kbd || !NILP (wait_for_cell); fix this.
1551 Add GCC-style 'const' attribute to functions that can use it.
1552 * character.h (char_resolve_modifier_mask):
1553 * keyboard.h (make_ctrl_char):
1554 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1555 (init_character_once, next_almost_prime, init_fns, init_image)
1556 (flush_pending_output, init_sound):
1557 * mem-limits.h (start_of_data):

1561 Declare the dummy function with ATTRIBUTE_CONST.
1562 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1563 Add decls with ATTRIBUTE_CONST.
1565 Minor improvements to make_formatted_string.
1566 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1567 where int is good enough, as vsprintf returns an int.
1568 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1570 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1572 Use make_formatted_string to avoid double length calculation.
1573 * lisp.h (make_formatted_string): New prototype.
1574 * alloc.c (make_formatted_string): New function.
1575 * buffer.c (Fgenerate_new_buffer_name): Use it.
1576 * dbus.c (syms_of_dbusbind): Likewise.
1577 * editfns.c (Fcurrent_time_zone): Likewise.
1578 * filelock.c (get_boot_time): Likewise.
1579 * frame.c (make_terminal_frame, set_term_frame_name)
1580 (x_report_frame_params): Likewise.
1581 * image.c (gs_load): Likewise.
1582 * minibuf.c (get_minibuffer): Likewise.

1595 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1597 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1599 Move marker debugging code under MARKER_DEBUG.
1600 * marker.c (MARKER_DEBUG): Move marker debugging code under
1601 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1602 for bootstrap with --enable-checking (~3x slowdown reported
1603 by Juanma Barranquero <lekktu@gmail.com>).
1604 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1606 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1608 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1609 See <http://bugs.gnu.org/11825#29>.
1611 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1613 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1614 has no font, use the frame's font. (Bug#11813)
1615 (display_line): Add commentary about displaying truncation glyphs
1617 (produce_special_glyphs): Move here from term.c.
1619 * term.c (produce_special_glyphs): Move to xdisp.c.
1621 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1624 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1626 * xdisp.c (display_line): Avoid warning about implicit declaration
1629 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1631 * lisp.h: Remove empty conditional.
1633 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1635 * lread.c (load_path_check): Now static.
1637 Fix some minor --with-ns problems found by static checking.
1638 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1639 (x_set_font) [!HAVE_X_WINDOWS]:
1640 * image.c (xpm_load_image) [HAVE_NS]:
1641 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1642 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1643 Remove unused local.
1644 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1645 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1646 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1647 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1648 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1649 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1650 Fix pointer signedness problem.
1651 * xfaces.c (FRAME_X_FONT_TABLE):
1652 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1654 2012-07-07 Glenn Morris <rgm@gnu.org>
1656 * lread.c (load_path_check): New function, split from init_lread.
1657 (init_lread): Reorganize. Motivation:
1658 If EMACSLOADPATH is set, check/warn about that rather than the
1659 defaults, which we are not going to use. Hence we can remove
1660 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1661 Don't warn if site-lisp directories are missing.
1662 If not installed, start from a blank load-path, since
1663 PATH_LOADSEARCH refers to the eventual installation directories.
1665 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1667 Support truncation and continuation glyphs on GUI frames, when
1668 fringes are disabled. (Bug#11832)
1669 * xdisp.c (init_iterator): Get dimensions of truncation and
1670 continuation glyphs even if on GUI frames. Adjust
1671 it->last_visible_x on GUI frames when the left or right fringes,
1672 or both, are absent.
1673 (start_display, move_it_in_display_line_to): Handle the case of a
1674 GUI frame without a fringe to display continuation or truncation
1676 (insert_left_trunc_glyphs): Support GUI frames: make sure
1677 truncation glyphs overwrite enough glyphs from the current line to
1678 have sufficient space in pixels.
1679 (display_line): Support truncation and continuation glyphs on GUI
1680 frames. If some spare pixels are left on the line after inserting
1681 the truncation glyphs, fill that space with a stretch glyph of a
1682 suitably computed width.
1684 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1685 produce_glyphs, to support GUI sessions.
1687 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1689 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1691 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1693 Do not require float-time's arg to fit in time_t (Bug#11825).
1694 This works better on hosts where time_t is unsigned, and where
1695 float-time is applied to the (negative) difference between two times.
1696 * editfns.c (decode_time_components): Last arg is now double *,
1697 not int *, and means to store all the result as a double, without
1698 worrying about whether the seconds part fits in time_t.
1699 All callers changed.
1700 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1701 All callers changed.
1702 (Ffloat_time): Do not fail merely because the specified time falls
1703 outside of time_t range.
1705 2012-07-07 Glenn Morris <rgm@gnu.org>
1707 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1708 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1709 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1711 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1713 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1714 Update dependencies.
1716 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1718 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1720 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1721 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1722 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1723 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1724 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1725 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1727 * xfont.c (compare_font_names): Redo to omit the need for casts.
1729 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1731 * xfns.c (Fx_change_window_property): Doc fix.
1732 * w32fns.c (Fx_change_window_property): Doc fix.
1734 * w32fns.c (Fx_window_property): Accept the same arguments as the
1735 X Windows version. Doc fix.
1736 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1738 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1739 Eli Zaretskii <eliz@gnu.org>
1741 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1742 Windows-specific code from nt/config.nt moved here.
1743 Obsolete settings removed.
1745 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1747 * process.c: Avoid unnecessary calls to gettime.
1748 (wait_reading_process_output): Don't get the time of day
1749 when gobbling data immediately and not waiting, as there's no need
1750 for it in that case. This removes a FIXME.
1752 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1754 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1755 is defined (Bug#11768).
1757 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1759 Fix marker debugging code.
1760 * marker.c (byte_char_debug_check): Do not perform the check
1761 if buffer is not multibyte.
1762 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1763 Call byte_char_debug_check with correct arguments.
1765 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1767 Compile marker debugging code only if ENABLE_CHECKING is defined.
1768 * marker.c (byte_char_debug_check, count_markers):
1769 Use only if ENABLE_CHECKING is defined.
1770 (byte_debug_flag): Remove.
1771 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1772 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1774 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1776 Avoid code repetition in marker-related functions.
1777 * marker.c (attach_marker): New function.
1778 (Fset_marker, set_marker_restricted, set_marker_both)
1779 (set_marker_restricted_both): Use it.
1780 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1781 Consistently rename charno to charpos.
1782 (marker_position): Add eassert.
1783 (marker_byte_position): Convert to eassert.
1785 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1787 Simplify list operations in unchain_overlay and unchain_marker.

1802 * window.c (save_window_save): Likewise.
1804 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1806 Do not use Fdelete_overlay in delete_all_overlays
1807 to avoid redundant calls to unchain_overlay.
1808 * buffer.c (drop_overlay): New function.
1809 (delete_all_overlays, Fdelete_overlay): Use it.
1810 * minibuf.c (get_minibuffer): Fix comment.
1812 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1814 Port to OpenBSD 5.1 amd64.
1815 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1816 This is needed for OpenBSD, and should be harmless on all BSD systems.
1817 Also, include <sys/sysctl.h>, as it should be available on all
1818 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1819 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1820 use p_pid member, not kp_proc.pid.
1822 2012-07-06 Glenn Morris <rgm@gnu.org>
1824 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1826 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1828 More xmalloc and related cleanup.

1830 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
1831 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
1832 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
1833 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:

1836 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1837 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1839 Omit needless casts involving void * pointers and allocation.
1840 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1841 as the former is more robust if P's type is changed.
1842 Prefer xzalloc to xmalloc + memset 0.
1843 Simplify malloc-or-realloc to realloc.
1844 Don't worry about xmalloc returning a null pointer.
1845 Prefer xstrdup to xmalloc + strcpy.
1846 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1848 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1849 alloca of a constant.
1851 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1853 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1854 hscroll is larger than the line width. Fixes long and futile
1855 looping inside extend_face_to_end_of_line (on a TTY) producing
1856 glyphs that are not needed and thrown away.
1858 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1860 * marker.c (set_marker_restricted_both): Simplify by using

1870 not defined (Bug#11768).
1871 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1872 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1873 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1874 followed by gtk_box_set_homogeneous (Bug#11768).
1875 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1876 (update_theme_scrollbar_width, xg_create_scroll_bar):
1877 Use gtk_scrollbar_new (Bug#11768).
1878 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

1886 * xdisp.c (window_hscroll_limited): New function.
1887 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1888 coordinates when window's hscroll is set to insanely large
1891 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1893 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1954 * fileio.c (time_error_value): Check the right error number.
1955 Problem reported by Troels Nielsen in
1956 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1958 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1960 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1961 This should be fixed in a better way; see Eli Zaretskii in
1962 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1963 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1965 * fileio.c (time_error_value): Rename from special_mtime.
1966 The old name's problems were noted by Eli Zaretskii in
1967 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1969 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1970 This variable's comment says Emacs needs at least one GDB-visible
1971 symbol of type enum pvec_type, to work around GDB problems.
1972 The symbol's value doesn't matter.
1974 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1975 that causes compilation to fail on pre-C99 compilers.
1977 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1979 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1985 headers for buffer_defaults and buffer_local_symbols.
1986 Reported by Juanma Barranquero <lekktu@gmail.com>.
1988 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1990 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1991 * lisp.h (enum pvec_type): Use fewer bits.
1992 (PSEUDOVECTOR_SIZE_BITS): New constant.
1993 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1994 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1995 change in pvec_type.
1996 (PSEUDOVECTOR_TYPEP): New macro.

2002 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2003 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2004 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2005 abusing vector->header.next.nbytes.
2006 (live_vector_p): Use PVEC_TYPE.
2007 (mark_object): Adapt code to extract pvectype. Use switch.
2009 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2011 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2012 Tighten new eassert a bit.
2014 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2016 Fix compilation with --enable-gcc-warnings and -O1
2018 * doprnt.c (doprnt): Change type of tem to int, initialize
2019 to avoid compiler warning. Add eassert.
2020 * search.c (simple_search): Initialize match_byte to avoid
2021 compiler warning. Add eassert.
2023 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2025 Avoid weird behavior with large horizontal scrolls.
2026 Without this change, for example, large hscroll values would
2027 mess up Emacs's display on Fedora 15 x86, presumably due to
2028 overflows in int calculations in the display code.
2029 Also, if buffers had long lines, Emacs would freeze.
2030 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2031 (set_window_hscroll): New function, containing the old guts of
2032 Fset_window_hscroll. Return the clipped value.
2033 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2034 This avoids the need to check against PTRDIFF_MAX.
2036 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2038 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2040 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2042 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2044 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2045 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2046 since GCC 4.4.6 issues a bogus warning for them.
2048 Fix bugs in file timestamp newness comparisons.
2049 * fileio.c (Ffile_newer_than_file_p):
2050 * lread.c (Fload): Use full timestamp resolution of files,
2051 not just the 1-second resolution, so that files that are only
2052 slightly newer still count as newer.
2053 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2054 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2056 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2058 * fileio.c: Improve handling of file time marker. (Bug#11852)
2059 (special_mtime): New function.
2060 (Finsert_file_contents, Fverify_visited_file_modtime):
2061 Use it to set special mtime values consistently.
2063 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2065 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2066 marker for non-existing file. (Bug#11852)
2068 2012-07-03 Glenn Morris <rgm@gnu.org>
2070 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2071 and did not make it into globals.h).
2073 2012-07-03 Tom Tromey <tromey@redhat.com>
2075 * window.c (Fset_window_margins, Fset_window_fringes)
2076 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2077 * textprop.c (Fprevious_property_change): No longer static.
2078 * syntax.c (Fsyntax_table_p): No longer static.
2079 * process.c (Fget_process, Fprocess_datagram_address): No longer

2100 * intervals.h: Remove EXFUNs.
2101 * fontset.h: Remove EXFUN.
2102 * font.h: Remove EXFUNs.
2103 * dosfns.c (system_process_attributes): Remove EXFUN.
2104 * keymap.h: Remove EXFUNs.

2106 * w32term.h: Remove EXFUNs.
2107 * window.h: Remove EXFUNs.
2108 * xsettings.h: Remove EXFUN.
2109 * xterm.h: Remove EXFUN.
2111 2012-07-03 Glenn Morris <rgm@gnu.org>
2113 * lisp.h (Frandom): Make it visible to C.
2114 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2115 buffer for invisible buffers. (Bug#1229)
2117 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2119 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2120 values which aren't power of 2.
2121 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2122 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2125 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2127 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2129 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2131 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2133 * alloc.c (allocate_vector_block): Remove redundant
2134 calls to mallopt if DOUG_LEA_MALLOC is defined.
2135 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2136 avoid calls to mallopt if zero_vector is returned.
2138 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2140 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2141 is enabled, avoid dereferencing NULL current_sblock if
2144 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2146 Cleanup basic buffer management.
2147 * buffer.h (struct buffer): Change layout to use generic vector
2148 marking code. Fix some comments. Change type of 'clip_changed'
2149 to bitfield. Remove unused #ifndef old.
2150 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2151 (GET_OVERLAYS_AT): Fix indentation.
2152 (for_each_per_buffer_object_at): New macro.
2153 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2155 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2156 * alloc.c (allocate_buffer): Adjust to match new layout of
2157 struct buffer. Fix comment.
2158 (mark_overlay): New function.

2161 (mark_object): Use it. Adjust marking of misc objects
2162 and related comments.
2164 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2166 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2167 wrapper that is not needed because the wrapped code is a no-op (zero
2168 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2169 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2171 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2173 * alloc.c (mark_buffer): Simplify. Remove prototype.
2174 (mark_object): Add comment. Reorganize marking of vector-like
2175 objects. Use CHECK_LIVE for all vector-like objects except buffers
2176 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2177 redundant calls to mark_vectorlike for bool vectors.
2179 2012-06-30 Glenn Morris <rgm@gnu.org>
2181 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2183 * epaths.in (PATH_SITELOADSEARCH): New.
2184 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2185 This is rather than relying on --enable-locallisppath elements
2186 having "site-lisp" in their names. (Bug#10208#25, 11658)
2188 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2190 * w32proc.c (sys_select): Accept and ignore one more argument.
2192 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2194 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2195 (pselect) [!MS_DOS]: Redirect to sys_select.
2197 * sysdep.c: Don't include dos.h and dosfns.h.
2199 * process.c (sys_select):
2200 * msdos.c (sys_select): Accept one more argument and ignore it.
2202 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2203 adapt data types and code to that.
2206 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2207 which clashes with the gnulib function of the same name.
2209 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2211 * font.c (font_style_to_value, font_style_symbolic)
2212 (font_prop_validate_style): Add type checks for values in
2215 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2217 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2220 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2222 * xdisp.c (try_window_id): Undo last change.
2224 * w32.c (getwd): Adjust commentary about startup_dir.
2225 (init_environment): Always call sys_access, even in non-MSVC
2226 builds. Don't chdir to the directory of the Emacs executable.
2227 This undoes code from 1997 which was justified by the need to
2228 "avoid conflicts when removing and renaming directories". But its
2229 downside was that every relative file name was being interpreted
2230 relative to the directory of the Emacs executable, which can never
2231 be TRT. In particular, it broke sys_access when called with
2232 relative file names.
2233 (sys_access): Map GetLastError to errno.
2235 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2237 * window.h (struct window): Change type of 'fringes_outside_margins'

2241 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2244 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2246 * gnutls.c (emacs_gnutls_handshake):
2247 Add QUIT to make the loop interruptible.
2249 2012-06-29 Glenn Morris <rgm@gnu.org>
2251 * charset.c (init_charset): Make lack of etc/charsets fatal.
2253 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2255 * editfns.c (region_limit): Fix type mismatch.
2257 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2259 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2260 undefined. Convert from xassert to eassert.
2261 * nsmenu.m: Convert from xassert to eassert.
2262 * nsterm.m: Likewise.
2264 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2266 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2268 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2270 Avoid integer overflow on scroll-left and scroll-right.
2271 * window.c (HSCROLL_MAX): New macro.
2272 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2273 overflow when requested scroll falls outside ptrdiff_t range.
2275 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2277 * window.h (struct window): Change type of 'hscroll',
2278 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2279 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2280 Adjust users accordingly.
2281 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2282 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2283 from EMACS_INT to ptrdiff_t.
2284 (make_window): Omit redundant initialization.
2286 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2288 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2290 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2292 * window.h (struct window): Change type of 'use_time' and
2293 'sequence_number' from Lisp_Object to int.
2294 * frame.c (make_frame): Adjust users accordingly.
2295 * print.c (print_object): Likewise.
2296 * window.c (select_window, Fwindow_use_time, make_parent_window)
2297 (make_window): Likewise.
2299 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2301 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2302 enabled with --enable-checking=[all,glyphs] configure option.
2303 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2304 adjust comments accordingly.
2305 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
2306 undefined, adjust comments accordingly.
2307 * image.c: Likewise.

2314 * xterm.c: Likewise.
2316 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

2425 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2427 Use sprintf return value instead of invoking strlen on result.
2428 In the old days this wasn't portable, since some sprintf
2429 implementations returned char *. But they died out years ago and
2430 Emacs already assumes sprintf returns int.
2431 Similarly for float_to_string.
2432 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2440 Use sprintf or float_to_string result to avoid need to call strlen.
2441 * data.c (Fnumber_to_string):
2442 Use make_unibyte_string, since the string must be ASCII.
2443 * lisp.h, print.c (float_to_string): Now returns int length.
2444 * term.c (produce_glyphless_glyph):
2445 Use sprintf result rather than recomputing it.
2447 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

2478 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2480 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2485 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2486 instead of truncating it to 63 (admittedly a generous limit).

2546 * keyboard.c (kbd_buffer_get_event):
2547 * process.c (Faccept_process_output):
2548 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2549 This improves on the previous patch, which introduced a bug
2550 when time_t is unsigned and as wide as intmax_t.
2551 See <http://bugs.gnu.org/9000#51>.

2570 Privately reported by Herbert J. Skuhra.
2571 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

2582 language ID in the event parameters.
2584 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2616 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2618 Support higher-resolution time stamps (Bug#9000).
2619 The time stamps are only nanosecond-resolution at the C level,
2620 since that's the best that any real-world system supports now.
2621 But they are picosecond-resolution at the Lisp level, as that's
2622 easy, and leaves room for future OS improvements.
2624 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2627 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2628 Don't get current time unless it's needed.
2630 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2631 now provides it if it's absent.
2632 (start_atimer): Port to higher-res time stamps.
2633 Check for time stamp overflow. Don't get current time more
2634 often than is needed.
2636 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2637 Include systime.h, not time.h.
2638 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2640 * dired.c: Include stat-time.h.
2641 (Ffile-attributes): File times now have higher resolution.

2644 (struct image): Timestamp now has higher resolution.
2646 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2647 has at least microseconds now. All uses removed.
2648 (update_frame, update_single_window, update_window, update_frame_1)
2649 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2651 * editfns.c (time_overflow): Now extern.
2652 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2653 (float-time, Fformat_time_string, Fcurrent_time_string)
2654 (Fcurrent_time_zone): Accept and generate higher-resolution

2657 (decode_time_components, lisp_seconds_argument): New functions.
2658 (make_time): Now static.
2659 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2660 Report an error if the time is invalid, rather than having the caller
2663 * fileio.c: Include <stat-time.h>
2664 (Fcopy_file): Copy higher-resolution time stamps.
2665 Prefer to set the time stamp via a file descriptor if that works.
2666 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2667 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2668 (Fvisited_file_modtime, Fset_visited_file_modtime):
2669 Support higher-resolution time stamps.
2671 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2673 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2675 * image.c (prepare_image_for_display, clear_image_cache)
2676 (lookup_image): Port to higer-resolution time stamps.
2678 * keyboard.c (start_polling, bind_polling_period):
2679 Check for time stamp overflow.
2680 (read_char, kbd_buffer_get_event, timer_start_idle)
2681 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2682 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2683 Port to higher-resolution time stamps. Do not assume time_t is signed.
2684 (decode_timer): New function. Timers are now vectors of length 9,
2685 not 8, to accommodate the picosecond component.
2686 (timer_check_2): Use it.
2688 * nsterm.m (select_timeout, timeval_subtract): Remove.
2689 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2690 as they're a bit more accurate and handle overflow better.
2691 (ns_select): Change prototype to be compatible with pselect.
2692 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2693 * nsterm.h (ns_select): Adjust prototype.
2695 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2696 us-resolution time stamps.
2697 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2699 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2701 * lisp.h (time_overflow): New decl.
2702 (wait_reading_process_output): First arg is now intmax_t, not int,
2703 to accommodate larger waits.
2705 * process.h (struct Lisp_Process.read_output_delay):
2706 Now counts nanoseconds, not microseconds.
2707 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2709 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2710 (wait_reading_process_output):
2711 Port to ns-resolution time stamps.
2712 (Faccept_process_output, wait_reading_process_output):
2713 Check for time stamp overflow. Do not assume time_t is signed.
2714 (select_wrapper): Remove; we now use pselect.
2715 (Fprocess_attributes): Now generates ns-resolution time stamps.
2717 * sysdep.c: Include utimens.h. Don't include utime.h
2718 or worry about struct utimbuf; gnulib does that for us now.
2719 (gettimeofday): Remove; gnulib provides a substitute.
2720 (make_timeval): New function.
2721 (set_file_times): Now sets ns-resolution time stamps.
2722 New arg FD; all uses changed.
2723 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2724 (system_process_attributes):
2725 Now returns ns-resolution time stamp. All uses changed.
2726 Check for time stamp overflow.
2728 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2729 provides a substitute now.
2731 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2732 since it guarantees struct timespec.
2733 (EMACS_TIME): Now struct timespec, so that we can support
2734 ns-resolution time stamps.
2735 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2736 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2737 (EMACS_USECS): Remove.
2738 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2739 so multiply the arg by 1000 before storing it.
2740 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2742 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2743 Port to ns-resolution time stamps.
2744 (EMACS_TIME_NEG_P): Remove; replaced by....
2745 (EMACS_TIME_SIGN): New macro.
2746 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2747 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2748 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2749 (make_timeval, make_lisp_time, decode_time_components): New decls.
2750 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2751 that it mishandled time_t overflow. You can't compare by subtracting!
2752 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2753 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2755 * term.c: Include <sys/time.h>.
2756 (timeval_to_Time): New function, for proper overflow wraparound.
2757 (term_mouse_position, term_mouse_click): Use it.
2759 * undo.c (record_first_change): Support higher-resolution time stamps
2761 (Fprimitive_undo): Use them when restoring time stamps.
2763 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2764 (w32_get_internal_run_time):
2765 Port to higher-resolution Emacs time stamps.
2766 (ltime): Now accepts single 64-bit integer, as that's more convenient
2769 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2771 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2772 for compatibility with pselect. Support ns-resolution time stamps.
2774 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2776 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2777 Check for time stamp overflow, and support ns-resolution time stamps.
2779 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2780 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2781 (timeval_subtract): Remove; no longer needed.
2782 (XTflash, XTring_bell, x_wait_for_event):
2783 Port to ns-resolution time stamps. Don't assume time_t is signed.
2785 2012-06-22 Chong Yidong <cyd@gnu.org>
2787 * xdisp.c (x_consider_frame_title): Revert last change.
2789 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2791 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2792 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2793 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2794 staticidx goes up to 1597 out of 1600 = 0x640.)
2796 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>

3068 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3069 Use an inline function on all platforms when using the union type,
3070 since this is simpler and 'static inline' can be used portably

3215 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3216 would mishandle a string argument "Xc" if X was a multibyte
3217 character of length 2: it would truncate after X's first byte
3218 rather than including all of X.

3277 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3280 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3282 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3284 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3286 For a 'struct window', replace some Lisp_Object fields to
3287 bitfields where appropriate, remove unused fields.
3288 * window.h (struct window): Remove unused 'last_mark_x' and
3289 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3290 change it's type from Lisp_Object to bitfield.
3291 Change type of 'force_start', 'optional_new_start',
3292 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3293 fields from Lisp_Object to bitfield. Adjust users accordingly.
3295 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3297 Pacify gcc -Wdouble-precision when using Xaw.
3298 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3299 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3300 Use 'float' consistently, rather than 'float' in most places
3301 and 'double' in a couple of places.
3303 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3305 * xdisp.c (handle_stop): Detect whether we have overlay strings
3306 loaded by testing it->current.overlay_string_index to be
3307 non-negative, instead of checking whether n_overlay_strings is
3308 positive. (Bug#11587)
3310 2012-05-31 Chong Yidong <cyd@gnu.org>
3312 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3314 * doc.c (Fsubstitute_command_keys): Doc fix.
3316 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3318 * search.c (search_buffer): Remove calls to
3319 r_alloc_inhibit_buffer_relocation, as it is now called by
3320 maybe_unify_char, which was the cause of relocation of buffer text
3323 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3325 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3326 for the duration of call to load_charset, to avoid problems with
3327 callers of maybe_unify_char that access buffer text through C
3330 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3331 decrement the inhibition flag, instead of just setting or
3334 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3336 Remove obsolete '#define static' cruft.
3337 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3338 This #undef was "temporary" in 2000; it is no longer needed
3339 now that '#define static' has gone away.
3340 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3341 (gray_bitmap_bits): Remove; no longer needed.
3342 All uses replaced with definiens.
3343 * xterm.c: Include "bitmaps/gray.xbm".
3345 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3347 Clean up __executable_start, monstartup when --enable-profiling.
3348 The following changes affect the code only when profiling.
3349 * dispnew.c (__executable_start): Rename from safe_bcopy.
3350 Define only on platforms that need it.
3351 * emacs.c: Include <sys/gmon.h> when profiling.
3352 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3353 (__executable_start): Remove decl, since lisp.h does it now.
3354 (safe_bcopy): Remove decl; no longer has that name.
3355 (main): Coalesce #if into single bit of code, for simplicity.
3356 Cast pointers to uintptr_t, since standard libraries want integers
3358 * lisp.h (__executable_start): New decl.
3360 2012-05-31 Glenn Morris <rgm@gnu.org>
3362 * image.c (Fimagemagick_types): Doc fix.
3364 2012-05-30 Jim Meyering <meyering@redhat.com>
3366 * callproc.c (Fcall_process_region): Include directory component
3367 in mkstemp error message (Bug#11586).
3369 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3371 * alloc.c, lisp.h (make_pure_vector): Now static.
3373 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

3379 (Qdefun): Move from eval.c.
3380 * lisp.h (Qdefun): Remove.
3381 * lread.c (read1): Tiny simplification.
3383 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3385 Do not create empty overlays with the evaporate property (Bug#9642).
3386 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3387 Bug#9642, but explicitly check that the buffer the overlay would
3388 be moved to is live and rearrange lines to make sure that errors
3389 will not put the overlay in an inconsistent state.
3390 (Fdelete_overlay): Cosmetics.
3392 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3394 * w32term.c (my_bring_window_to_top): New function.
3395 (x_raise_frame): Use handle returned by DeferWindowPos, which
3396 could be different from the original one.
3397 Call my_bring_window_to_top instead of my_set_foreground_window.
3400 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3401 by calling BringWindowToTop.
3403 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3404 (WM_EMACS_END): Increase by one.
3406 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3408 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3409 This avoids undefined behavior that might cause the eassert
3410 to not catch an out-of-range value.
3412 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3414 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3415 Update dependencies.
3417 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3419 * bidi.c (bidi_mirror_char): Fix last change.
3421 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3423 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3424 when referring to sectname field in printf format.
3426 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3428 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3429 Only r_alloc_inhibit_buffer_relocation needed to be added;
3430 the others were already declared.
3432 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3433 before checking whether it's out of range. Put the check inside
3435 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3437 2012-05-27 Ken Brown <kbrown@cornell.edu>
3439 * callproc.c (Fcall_process): Restore a line that was accidentally
3440 commented out in the 2011-02-13 change (bug#11547).
3442 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3444 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3445 defined on ralloc.c.
3447 * buffer.c [REL_ALLOC]: Remove prototypes of
3448 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3449 they are now on lisp.h.
3451 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3453 * search.c (search_buffer): Use it to inhibit relocation of buffer
3454 text while re_search_2 is doing its job, because re_search_2 is
3455 passed C pointers to buffer text. (Bug#11519)
3457 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3460 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3461 state after an additional call to move_it_in_display_line_to, keep
3462 the values of it->max_ascent and it->max_descent found for the
3464 (pos_visible_p): Revert the comparison against bottom_y to what it
3465 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3468 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3470 Fix coding-related core dumps with gcc -ftrapv.
3471 The code was computing A - B, where A and B are pointers, and B is
3472 random garbage. This can lead to core dumps on platforms that
3473 have special pointer registers, and it also leads to core dumps on
3474 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3475 A - B only when B is initialized properly.
3476 * coding.c (coding_set_source, coding_set_destination): Return void.
3477 (coding_change_source, coding_change_destinations): New functions,
3478 with the old behaviors of coding_set_source and coding_set_destination.
3479 All callers that need an offset changed to use these new functions.
3481 2012-05-26 Glenn Morris <rgm@gnu.org>
3483 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3485 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3487 Extend mouse support on W32 text-mode console.
3488 * xdisp.c (draw_row_with_mouse_face):
3489 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3491 * w32console.c: Include window.h.
3492 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3494 (initialize_w32_display): Initialize mouse-highlight data.
3496 * w32inevt.c: Include termchar.h and window.h.
3497 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3498 moves, call note_mouse_highlight. If help_echo changed, call
3499 gen_help_event to produce help-echo message in the echo area.
3500 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3503 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3505 * lread.c (read1): Simplify slightly to avoid an overflow warning
3506 with GCC 4.7.0 on x86-64.
3508 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3510 * bidi.c (bidi_mirror_char): Revert last change: an int is
3511 definitely wide enough here.
3513 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3515 Fix integer width and related bugs (Bug#9874).
3516 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3517 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3518 (string_bytes, check_sblock, allocate_string_data):
3519 (compact_small_strings, Fmake_bool_vector, make_string)

3521 (make_string_from_bytes, make_specified_string)
3522 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3523 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3525 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3526 (allocate_pseudovector):
3527 Use int, not EMACS_INT, where int is wide enough.
3528 (inhibit_garbage_collection, Fgarbage_collect):
3529 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3530 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3531 int might not be wide enough.
3532 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3533 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3534 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3535 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3536 (bidi_level_of_next_char, bidi_move_to_visually_next):
3537 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3538 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3539 (Fkill_buffer, Fset_buffer_major_mode)
3540 (advance_to_char_boundary, Fbuffer_swap_text)
3541 (Fset_buffer_multibyte, overlays_at, overlays_in)
3542 (overlay_touches_p, struct sortvec, record_overlay_string)
3543 (overlay_strings, recenter_overlay_lists)
3544 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3545 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3546 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3547 (Foverlay_recenter, last_overlay_modification_hooks_used)
3548 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3549 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3550 (validate_region): Omit unnecessary test for b <= e,
3551 since that's guaranteed by the previous test.
3552 (adjust_overlays_for_delete): Avoid pos + length overflow.
3553 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3554 (report_overlay_modification):
3555 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3556 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3557 Omit pointer cast, which isn't needed anyway, and doesn't work
3558 after the EMACS_INT -> ptrdiff_t change.
3559 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3560 * buffer.h: Adjust decls to match defn changes elsewhere.
3561 (struct buffer_text, struct buffer):
3562 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3563 Use EMACS_INT, not int, where int might not be wide enough.
3564 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3565 not int, to avoid needless 32-bit limit on 64-bit hosts.
3566 (exec_byte_code): Use tighter memory-full test, one that checks
3567 for alloca overflow. Don't compute the address of the object just
3568 before an array, as that's not portable. Use EMACS_INT, not
3569 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3570 * callint.c (Fcall_interactively):
3571 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3572 * callproc.c (call_process_kill, Fcall_process):
3573 Don't assume pid_t fits into an Emacs fixnum.
3574 (call_process_cleanup, Fcall_process, child_setup):

3576 (call_process_cleanup, Fcall_process, delete_temp_file)
3577 (Fcall_process_region):
3578 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3579 (Fcall_process): Simplify handling of volatile integers.
3580 Use int, not EMACS_INT, where int will do.
3581 * casefiddle.c (casify_object, casify_region, operate_on_word)
3582 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3583 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3584 (casify_object): Avoid integer overflow when overallocating buffer.
3585 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3586 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3587 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3588 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3589 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3590 integers are now checked earlier. All uses replaced with XINT.
3592 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3593 For CCL_MapSingle, check that content and value are in int range.
3594 (ccl_driver, Fregister_code_conversion_map):
3595 Check that Vcode_version_map_vector is a vector.
3596 (resolve_symbol_ccl_program): Check that vector header is in range.
3597 Always copy the vector, so that we can check its contents reliably
3598 now rather than having to recheck each instruction as it's being
3599 executed. Check that vector words fit in 'int'.
3600 (ccl_get_compiled_code, Fregister_ccl_program)
3601 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3602 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3603 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3604 contents are in range.
3605 (Fccl_execute_on_string): Check that status is in range.
3606 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3607 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3608 Accept and return EMACS_INT, not int, because callers can pass values
3610 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3611 (multibyte_chars_in_text, parse_str_as_multibyte)
3612 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
3613 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3614 (string_escape_byte8, Fget_byte):
3615 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3616 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3617 avoid mishandling large integers.
3618 * character.h: Adjust decls to match defn changes elsewhere.
3619 * charset.c (load_charset_map_from_file, find_charsets_in_text)
3620 (Ffind_charset_region):
3621 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3622 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
3623 (load_charset_map_from_vector, Fdefine_charset_internal):
3624 Don't assume fixnum fits in int.
3625 (load_charset_map_from_vector, Fmap_charset_chars):
3626 Remove now-unnecessary CHECK_NATNUMs.
3627 (Fdefine_charset_internal): Check ranges here, more carefully.
3628 Don't rely on undefined behavior with signed left shift overflow.
3629 Don't assume unsigned int fits into fixnum, or that fixnum fits
3630 into unsigned int. Don't require max_code to be a valid fixnum;
3631 that's not true for gb10830 4-byte on a 32-bit host. Allow
3632 invalid_code to be a cons, for the same reason. Require code_offset
3633 to be a character. Avoid int overflow if max_char is close
3635 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3636 this is intended anyway and avoids some undefined behavior.
3637 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3638 INDEX_TO_CODE_POINT, as that's what it expects.
3639 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3640 * charset.h (DECODE_CHAR): Return int, not unsigned;
3641 this is what was intended anyway, and it avoids undefined behavior.
3642 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3643 integer-overflow issues.
3644 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3645 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3646 where the argument is EMACS_INT, and this behavior is not intended.
3647 * chartab.c (Fmake_char_table, Fset_char_table_range)
3648 (uniprop_get_decoder, uniprop_get_encoder):
3649 Don't assume fixnum fits in int.
3650 * cmds.c (move_point): New function, that does the gist of
3651 Fforward_char and Fbackward_char, but does so while checking
3652 for integer overflow more accurately.
3653 (Fforward_char, Fbackward_char): Use it.
3654 (Fforward_line, Fend_of_line, internal_self_insert)
3655 (internal_self_insert):
3656 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3657 Fix a FIXME, by checking for integer overflow when calculating
3658 target_clm and actual_clm.
3659 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

3683 (setup_iso_safe_charsets, consume_chars, Funencodable_char_position)
3684 (Fdefine_coding_system_internal):
3685 Don't assume fixnums fit in int.

3688 (Funencodable_char_position, Fcheck_coding_systems_region)
3689 (get_translation, handle_composition_annotation, consume_chars):
3690 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3691 (consume_chars): Rewrite to not calculate an address outside buffer.

4411 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4413 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4415 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4416 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4418 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4419 reference to image_cache->refcount.
4420 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4422 2012-05-17 Juri Linkov <juri@jurta.org>
4424 * search.c (Fword_search_regexp, Fword_search_backward)
4425 (Fword_search_forward, Fword_search_backward_lax)
4426 (Fword_search_forward_lax): Move functions to isearch.el
4427 (bug#10145, bug#11381).
4429 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4431 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4433 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4435 * lread.c (init_obarray): Declare Qt and Qnil as special.
4437 2012-05-14 Glenn Morris <rgm@gnu.org>
4439 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4440 Put "libexec" before "bin", for the sake of init_callproc_1.
4442 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4444 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4446 * unexaix.c: Port to more-recent AIX compilers.
4447 (report_error, report_error_1, make_hdr, copy_sym)
4448 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4449 Make arguments const char *, not char *, to avoid violations of C
4450 standard and to fix some AIX warnings reported by Gilles Pion.
4452 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4454 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4455 already have overlays loaded.
4456 (handle_single_display_spec): Before returning without displaying
4457 fringe bitmap, synchronize the bidi iterator with the main display
4458 iterator, by calling iterate_out_of_display_property.
4459 (iterate_out_of_display_property): Detect buffer iteration by
4460 testing that it->string is a Lisp string.
4461 (get_next_display_element): When the current object is exhausted,
4462 and there's something on it->stack, call set_iterator_to_next to
4463 proceed with what's on the stack, instead of returning zero.
4464 (set_iterator_to_next): If called at the end of a Lisp string,
4465 proceed to consider_string_end without incrementing string
4466 position. Don't increment display vector index past the end of
4467 the display vector. (Bug#11417)
4468 (pos_visible_p): Don't report a position visible when move_it_to
4469 stopped at the last line of window, which happens to be scanned
4470 backwards by the bidi iteration. (Bug#11464)
4472 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4474 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4475 and right-margin display specs even if the spec is invalid or we
4476 are on a TTY, and thus unable to display on the fringes.
4477 That's because the text with the property will not be displayed anyway,
4478 so we need to signal to the caller that this is a "replacing"
4479 display spec. This fixes display when the spec is invalid or we
4482 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4484 * unexaix.c (make_hdr): Fix typo in prototype.
4485 This bug broke the build on AIX. Problem reported by Gilles Pion.
4487 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4489 * keyboard.c (kbd_buffer_get_event): Read special events also in
4490 batch mode. (Bug#11415)
4492 2012-05-12 Glenn Morris <rgm@gnu.org>
4494 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4496 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4498 * lisp.mk (lisp): Add newcomment.elc.
4500 2012-05-12 Glenn Morris <rgm@gnu.org>
4502 * Makefile.in (MKDIR_P): New, set by configure.
4503 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4505 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4507 Remove unused function hourglass_started.
4508 * dispextern.h (hourglass_started):
4509 * w32fns.c (hourglass_started):
4510 * xdisp.c (hourglass_started): Remove.
4512 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4514 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4515 Update dependencies.
4517 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4519 * xgselect.c (xg_select): Put maxfds+1 into a var.
4520 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4522 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4524 2012-05-10 Dave Abrahams <dave@boostpro.com>
4526 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4527 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4529 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4531 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4532 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4533 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4534 Initialize xd_registered_buses.
4536 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4538 Untag more efficiently if USE_LSB_TAG.
4539 This is based on a proposal by YAMAMOTO Mitsuharu in
4540 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4541 For an admittedly artificial (nth 8000 longlist) benchmark on
4542 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4543 Emacs's overall text size by 1%.
4544 * lisp.h (XUNTAG): New macro.
4545 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4546 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4547 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4548 * eval.c (Fautoload):
4549 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4550 * frame.h (XFRAME): Use XUNTAG.
4552 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4553 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4554 Remove unportable assumptions about print widths of types like
4556 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4557 intptr_t when converting between pointer and integer, to avoid GCC
4558 warnings about wrong width.
4560 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4562 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4563 stack for each reader_thread, instead of defaulting to 8MB
4564 determined by the linker. This avoids failures in creating
4565 subprocesses on Windows 7, see the discussion in this thread:
4566 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4568 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4570 Fix up display of the *Minibuf-0* buffer in the mini window.
4571 * keyboard.c (read_char): Don't clear the echo area if there's no
4573 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4574 contents of *Minibuf-0*) if there's no message displayed in its stead.
4576 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4578 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4581 2012-05-06 Chong Yidong <cyd@gnu.org>
4583 * lisp.mk (lisp): Update.
4585 2012-05-05 Jim Meyering <meyering@redhat.com>
4587 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4589 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4591 * data.c (PUT_ERROR): New macro.
4592 (syms_of_data): Use it. Add new error type `user-error'.
4593 * undo.c (user_error): New function.
4594 (Fprimitive_undo): Use it.
4595 * print.c (print_error_message): Adjust print style for `user-error'.
4596 * keyboard.c (user_error): New function.
4597 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4599 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4601 Do not limit current-time-string to years 1000..9999.
4602 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4603 (Fcurrent_time_string): Support any year that is supported by the
4604 underlying localtime representation. Don't use asctime, as it
4605 has undefined behavior for years outside the range -999..9999.
4607 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4609 Fix race conditions involving setenv, gmtime, localtime, asctime.
4610 Without this fix, interrupts could mess up code that uses these
4611 nonreentrant functions, since setting TZ invalidates existing
4612 tm_zone or tzname values, and since most of these functions return
4613 pointers to static storage.
4614 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4615 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4616 Grow the critical sections to include not just invoking
4617 localtime/gmtime, but also accessing these functions' results
4618 including their tm_zone values if any, and any related TZ setting.
4619 (format_time_string): Last arg is now struct tm *, not struct tm **,
4620 so that the struct tm is saved in the critical section.
4621 All callers changed. Simplify allocation of initial buffer, partly
4622 motivated by the fact that memory allocation needs to be outside
4623 the critical section.
4625 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4627 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4628 with RESET_INTERVAL.
4630 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4631 Remove duplicated buffer name initialization.
4633 2012-05-02 Jim Meyering <jim@meyering.net>
4635 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4637 * xfns.c (x_window): Use xstrdup (Bug#11375).
4639 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4641 * xdisp.c (pos_visible_p): If already at a newline from the
4642 display string before the 'while' loop, don't walk back the glyphs
4643 from it3.glyph_row. Solves assertion violation when the display
4644 string begins with a newline (egg.el). (Bug#11367)
4646 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4648 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4651 2012-05-01 Glenn Morris <rgm@gnu.org>
4653 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4654 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4655 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4656 All were removed before 23.1.
4658 * dispnew.c: Remove HAVE_LIBNCURSES test;
4659 it is always true on relevant platforms.
4661 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4662 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4664 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4666 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4668 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4669 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4672 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4674 Do not avoid creating empty evaporating overlays (Bug#9642).
4675 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4676 That is, do not delete an evaporating overlay if it becomes
4677 empty after its bounds are adjusted to fit within its buffer.
4678 This fix caused other problems, and I'm reverting it until we get
4679 to the bottom of them.
4681 2012-04-27 Chong Yidong <cyd@gnu.org>
4683 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4685 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4687 * xdisp.c (pos_visible_p): If the window start position is beyond
4688 ZV, start the display from buffer beginning. Prevents assertion
4689 violation in init_iterator when the minibuffer window is scrolled
4692 * window.c (window_scroll_pixel_based): Likewise.
4694 2012-04-27 Chong Yidong <cyd@gnu.org>
4696 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4698 2012-04-27 Glenn Morris <rgm@gnu.org>
4700 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4701 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4703 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4705 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4706 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4708 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4710 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4711 display element, check also the underlying string or buffer
4712 character. (Bug#11341)
4714 * w32menu.c: Include w32heap.h.
4715 (add_menu_item): If the call to AppendMenuW (via
4716 unicode_append_menu) fails, disable Unicode menus only if we are
4717 running on Windows 9X/Me.
4719 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4721 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4722 (xgetint): Add missing shift for LSB tags.
4724 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4726 * keyboard.c (read_char): Don't wipe echo area for select window
4727 events: These might get delayed via `mouse-autoselect-window'
4730 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4732 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4733 manipulation of :loaded-from data.
4735 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4737 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4738 now a cons (bug#11311).
4740 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4742 Do not create empty overlays with the evaporate property (Bug#9642).
4743 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4744 if it becomes empty after its bounds are adjusted to fit within
4745 its buffer. Without this fix, in a nonempty buffer (let ((o
4746 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4747 yields an empty overlay that has the evaporate property, which is
4748 not supposed to happen.
4750 Fix minor GTK3 problems found by static checking.
4751 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4752 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4753 (struct _EmacsFixedClass, emacs_fixed_get_type):
4754 Move decls here from emacsgtkfixed.h, since they needn't be public.

4756 (emacs_fixed_class_init): Omit unused local.
4757 (emacs_fixed_child_type): Remove; unused.

4760 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4761 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4762 (EMACS_FIXED_GET_CLASS): Remove; unused.
4763 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4765 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4766 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4768 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4770 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4771 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4772 (__malloc_size_t, __malloc_ptrdiff_t):
4773 Remove. All uses removed, replaced by the definiens if needed,
4774 since we can assume C89 or better now.
4775 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4776 (protect_malloc_state, align, get_contiguous_space)
4777 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4783 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4784 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4785 Define using prototypes, not old style.
4786 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4787 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4788 (align): Don't assume that signed integer overflow wraps around.
4789 Omit unused local var.
4790 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4791 (_free_internal_nolock, memalign, mallochook, reallochook):
4792 Omit no-longer-needed casts.
4793 (valloc): Use getpagesize, not __getpagesize.
4794 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
4795 (struct hdr): The 'magic' member is now size_t, not unsigned long.
4797 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4799 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
4801 Move functions from C to Lisp. Make non-blocking method calls
4802 the default. Implement further D-Bus standard interfaces.
4804 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
4805 (QCdbus_request_name_allow_replacement)

4844 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4846 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
4847 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
4848 Do not assume ptrdiff_t is the same width as 'int'.
4850 * alloc.c: Handle unusual debugging option combinations.
4851 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4852 since the two debugging options are incompatible.
4853 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4855 (mem_init, mem_insert, mem_insert_fixup):
4856 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
4857 (NEED_MEM_INSERT): Remove; no longer needed.
4859 2012-04-22 Leo Liu <sdl.web@gmail.com>

4886 * print.c (print_preprocess): Only check print_depth if print-circle
4888 (print_object): Check for cycles even when print-circle is nil and
4889 print-gensym is t, but only check print_depth if print-circle is nil.
4891 2012-04-20 Chong Yidong <cyd@gnu.org>
4893 * process.c (wait_reading_process_output): If EIO occurs on a pty,

4909 farther than the first row after the header line, if any.
4910 Don't consider the header-line row as "partially visible", even if
4911 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4913 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4948 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
4949 New extern decls, to avoid calling undeclared functions.
4950 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4951 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4952 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4953 (NEED_MEM_INSERT): New macro.
4954 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4955 Remove one incorrect comment and fix another.

4969 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4970 Remove decls. This fixes an "It stinks!".
4972 * alloc.c (which_symbols): Fix alignment issue / type clash.
4974 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4976 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4991 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4992 * s/netbsd.h, s/sol2-6.h:
4993 Remove definition of GC_MARK_STACK, since the default now works.
4994 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4995 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4996 no longer the default.
4997 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4999 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5001 * lread.c (lisp_file_lexically_bound_p):

5022 2012-04-11 Daniel Colascione <dancol@dancol.org>
5024 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5025 against is gone. It's better to use vfork now so that when Cygwin
5026 gains a new, working vfork, we use it automatically (bug#10398).
5028 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5044 (handle_interrupt): Use it.
5046 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5048 * w32.c (w32_delayed_load): Record the full path of the library
5049 being loaded (bug#10424).
5051 2012-04-09 Glenn Morris <rgm@gnu.org>
5053 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5054 not just in the obarray, before snarfing them. (Bug#11036)
5056 * Makefile.in ($(leimdir)/leim-list.el):
5057 Pass EMACS rather than BUILT_EMACS.

5066 Add convenience `GNUTLS_LOG2i' macro.
5068 * gnutls.c (gnutls_log_function2i): Convenience log function.
5069 (emacs_gnutls_read): Use new log functions,
5070 `gnutls_handshakes_tried' process member, and

5081 * minibuf.c (Fread_variable): Callers changed.
5083 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5085 * xdisp.c (set_cursor_from_row): If the display string appears in
5086 the buffer at position that is closer to point than the position
5087 after the display string, display the cursor on the first glyph of
5088 the display string. Fixes cursor display when a 'display' text
5089 property immediately follows invisible text. (Bug#11094)
5091 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5093 composite.c: use 'double' consistently
5094 * composite.c (get_composition_id): Use 'double' consistently
5095 instead of converting 'float' to 'double' and vice versa; this is
5096 easier to understand and avoids a GCC warning.
5098 2012-04-09 Glenn Morris <rgm@gnu.org>
5100 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5101 preparation for dumping it with emacs. (Bug#4789)

5123 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5124 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5125 objects, as mark_maybe_pointer will catch them otherwise.
5126 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5127 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5129 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5131 Fix typo that broke non-Windows builds.
5132 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5143 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5144 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5145 [!WINDOWSNT]: New macros.
5146 (init_libxml2_functions, libxml2_loaded_p): New functions.
5147 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5148 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5149 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5150 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5152 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5153 Call init_libxml2_functions before calling libxml2 functions.
5154 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5156 * emacs.c: Don't include libxml/parser.h.
5157 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5158 xmlCleanupParser directly.
5160 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5162 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5164 * indent.c (Fvertical_motion): If there is a display string at
5165 point, use it.vpos to compute how many lines to backtrack after
5166 move_it_to point. (Bug#11133)
5168 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5170 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5171 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5172 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5173 macros related to unification of CJK characters. For the details,
5174 see the discussion following the message here:
5175 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5177 2012-04-04 Chong Yidong <cyd@gnu.org>
5179 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5181 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5183 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5191 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5193 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5194 position we get to after a call to move_it_to fails the
5195 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5196 only if we wind up in a string from display property. (Bug#11063)
5198 * window.c (Fdelete_other_windows_internal): Invalidate the row
5199 and column information about mouse highlight, so that redisplay
5200 restores it after reallocating the glyph matrices. (Bug#7464)
5202 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5203 string comes from a `display' text property, use the buffer
5204 position of that property as if we actually saw that position in
5206 (move_it_by_lines): Remove the assertion that
5207 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5208 violated when there's a before-string at the beginning of a line.
5211 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5213 * xdisp.c (append_space_for_newline): If the default face was
5214 remapped, use the remapped face for the appended newline.
5215 (extend_face_to_end_of_line): Use the remapped default face for
5216 extending the face to the end of the line.
5217 (display_line): Call extend_face_to_end_of_line when the default
5218 face was remapped. (Bug#11068)
5220 2012-03-29 Eli Zaretskii <eliz@gnu.org>

5242 handle-select-window too (Bug#8996).
5244 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5246 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5248 2012-03-25 Kenichi Handa <handa@m17n.org>
5250 * dispextern.h (struct glyph): Change the bit length of
5251 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5253 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5255 * s/ms-w32.h (tzname): Include time.h before redirecting to
5256 _tzname. Fixes the MSVC build. (Bug#9960)
5258 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5260 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5263 * xterm.c (XTread_socket): Only modify handling_signal if

5266 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5268 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5269 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5270 when fetching a multibyte character consumes more bytes than
5271 CHAR_BYTES returns, due to unification of CJK characters in
5272 string_char. (Bug#11073)
5274 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5276 * process.c (wait_reading_process_output): Handle pty disconnect
5277 by refraining from sending oneself a SIGCHLD (bug#10933).

5288 2012-03-21 Chong Yidong <cyd@gnu.org>
5290 * xfaces.c (Vface_remapping_alist): Doc fix.
5292 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5294 * w32proc.c (Fw32_set_console_codepage)
5295 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5306 it fit in a valid range (Bug#11003).
5308 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5310 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5311 that is not from display property, accept the row as a "cursor
5312 row" if one of the string's character has a non-nil `cursor'
5313 property. Fixes cursor positioning when there are newlines in
5314 overlay strings, e.g. in icomplete.el. (Bug#11035)
5316 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5318 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5320 2012-03-12 Chong Yidong <cyd@gnu.org>
5322 * eval.c (inhibit_lisp_code): Rename from
5323 inhibit_window_configuration_change_hook; move from window.c.
5325 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5326 * window.c (run_window_configuration_change_hook)
5327 (syms_of_window): Callers changed.
5329 2012-03-11 Chong Yidong <cyd@gnu.org>
5331 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5333 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
5335 2012-03-10 Chong Yidong <cyd@gnu.org>
5337 * frame.c (other_visible_frames): Don't assume the selected frame

5347 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5350 2012-03-03 Glenn Morris <rgm@gnu.org>

5365 * buffer.c (buffer-list-update-hook): Doc fix.
5367 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5370 push_it before setting up the iterator for the first overlay
5371 string, even if we have an empty string loaded.
5372 (next_overlay_string): If there's an empty string on the iterator
5373 stack, pop the stack. (Bug#10903)
5375 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5377 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5378 Suggested by Stefan Monnier in
5379 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5380 * alloc.c (widen_to_Lisp_Object): New static function.
5381 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5382 and widening them to Lisp_Objects. This would work even if
5383 USE_LSB_TAG is defined and wide integers are used, which might
5384 happen in a future version of Emacs.
5386 2012-02-25 Chong Yidong <cyd@gnu.org>
5388 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

5403 call when setting menu-bar-lines and tool-bar-lines parameters.
5404 (unwind_create_frame_1): New helper function.
5406 * window.c (inhibit_window_configuration_change_hook): New var.
5407 (run_window_configuration_change_hook): Obey it.
5408 (syms_of_window): Initialize it.
5410 2012-02-22 Chong Yidong <cyd@gnu.org>

5425 when computing $valmask.
5427 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5428 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5429 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5430 It's useless in that case, and it can cause problems on hosts
5431 that allocate halves of EMACS_INT values separately.
5432 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5433 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5434 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5435 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5436 it avoids undefined behavior on hosts where shifting right by more
5437 than the word width has undefined behavior.
5439 2012-02-19 Chong Yidong <cyd@gnu.org>
5441 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5442 (Funhandled_file_name_directory, Ffile_name_as_directory)

5461 2012-02-15 Chong Yidong <cyd@gnu.org>
5463 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5464 marked as special. Also, starting docstrings with * is obsolete.

5481 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5482 as that creates a dangerous corner case.
5484 * window.c (Fdelete_window_internal): Invalidate the mouse
5485 highlight (Bug#9904).
5487 2012-02-12 Glenn Morris <rgm@gnu.org>

5517 2012-02-07 Chong Yidong <cyd@gnu.org>
5519 * buffer.c (Fbuffer_local_variables)
5520 (buffer_lisp_local_variables): Handle unbound vars correctly;
5521 don't let Qunbound leak into Lisp.
5523 2012-02-07 Glenn Morris <rgm@gnu.org>
5525 * image.c (Fimagemagick_types): Doc fix.
5527 * image.c (imagemagick-render-type): Change it from a lisp object

5562 Handle overflow when computing char display width (Bug#9496).
5563 * character.c (char_width): Return EMACS_INT, not int.
5564 (char_width, c_string_width): Check for overflow when
5565 computing the width; this is possible now that individual
5566 characters can have unbounded width. Problem introduced
5567 by merge from Emacs 23 on 2012-01-19.
5569 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

5709 (Fmake_directory_internal): Use it.
5710 (do_auto_save_make_dir): Set it, instead of invoking chmod after

5712 too-generous permissions to the directory.
5713 (do_auto_save_eh): Clear it.
5714 (Fdo_auto_save): Catch all errors, not just file errors, so

6225 to 4 (xorl, subq, cmpq, setbe).
6226 * alloc.c (pure): Always extern now, since that's the

6239 behave as if the cursor position were at the window margin.
6241 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6242 and the cursor position is out of bounds, behave as if the cursor

6273 * dispnew.c (verify_row_hash): Call row_hash for computing the
6274 hash code of a row, instead of duplicating code from xdisp.c.
6276 * dispextern.h (row_hash): Add prototype.
6278 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6280 * frame.c (delete_frame): Don't delete the terminal when the last

6308 occurrences of window_nest to window_combination_limit.
6310 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6312 * image.c (imagemagick_load_image): Fix typo.
6314 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6316 * xdisp.c (display_line): Move the call to

6383 Avoid some portability problems by eschewing 'extern inline' functions.
6384 The trivial performance wins aren't worth the portability hassles; see
6385 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6387 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6435 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6436 This is also needed for porting to any host where GC_MARK_STACK is
6437 not GC_MAKE_GCPROS_NOOPS.
6438 (which_symbols): Use it.
6440 2011-11-07 Kenichi Handa <handa@m17n.org>

6461 (window_box_width, window_box_left, window_box_left_offset)
6462 (window_box_right, window_box_right_offset): Declare extern.
6463 Otherwise, these inline functions do not conform to C99 and
6464 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6465 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6466 * intervals.c (adjust_intervals_for_insertion)
6467 (adjust_intervals_for_deletion): Now extern, because otherwise the
6468 extern inline functions 'offset_intervals' couldn't refer to it.
6469 (static_offset_intervals): Remove.
6470 (offset_intervals): Rewrite using the old contents of
6471 static_offset_intervals. The old version didn't conform to C99
6472 because an extern inline function contained a reference to an
6473 identifier with static linkage.

6495 (Fwindow_vscroll): Doc fix.
6496 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6497 argument, since it makes no sense to pass a live window and for

6644 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6645 so that this new function doesn't get optimized away by a

6786 * editfns.c: Rewrite current-time-zone so that it invokes
6787 the equivalent of (format-time-string "%Z") to get the time zone name.
6788 This fixes a bug when the time zone name contains characters that
6789 need converting from the system time locale to Emacs internal format.
6790 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6791 that patch fixed format-time-string to do the conversion, but
6792 I forgot to fix current-time-zone.
6793 (format_time_string): New function, containing most of
6794 what Fformat_time_string used to contain.
6795 (Fformat_time_string): Rewrite in terms of format_time_string.

6797 (current-time-zone): Rewrite to use format_time_string.
6798 This fixes the bug reported by Michael Schierl in
6799 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6800 Jason Rumney's 2007-06-07 change worked around this bug, but
6802 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6804 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6806 * xdisp.c (start_display): If the character at POS is displayed
6807 via a display vector, reset IT->current.dpvec_index to zero.
6808 (try_window_reusing_current_matrix): If a line ends in a display
6809 vector or the next line starts in a display vector, continue
6810 redrawing the window even though the character position of
6811 start_row was reached.
6814 2011-10-18 Chong Yidong <cyd@gnu.org>
6816 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6817 with nobreak-char-display too.
6819 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6821 Fix part 3 of bug#9771.
6822 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6823 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6824 non-neutral characters if the current character is a paragraph
6825 separator (a.k.a. Newline). This avoids running the same
6826 expensive loop twice, once when we consume the preceding newline
6827 and the other time when the line actually needs to be displayed.
6828 Avoid the loop when we see neutrals on the base embedding level
6829 following a character whose directionality is the same as the
6830 paragraph's. This avoids running the expensive loop when a line
6831 ends in a long sequence of neutrals, like control characters.
6832 Add assertion against STRONG_AL type. Slightly rearrange code
6833 that determines the type of a neutral given the first non-neutral
6835 (bidi_level_of_next_char): Set next_en_pos to zero when
6836 invalidating its info.
6838 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6840 * xdisp.c (push_display_prop): Determine whether to record string
6841 or buffer position by IT->string, not by IT->method. Allow
6842 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6843 (move_it_vertically_backward): Don't look for character position
6844 immediately after the newline when in a continuation line.
6847 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6849 * window.c (coordinates_in_window): Rewrite and delabelize
6850 vertical border check. (Bug#5357) (Bug#9618)
6852 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6854 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6855 errors in XSetWindowBorder (bug#9310).
6857 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6859 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6860 avoid crash when xmalloc overrun checking is enabled.
6862 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6864 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6865 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6866 cursor motion with <left> and <right> arrow keys.
6868 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6869 some callers set that themselves.
6871 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6873 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6874 display string and the previous row comes from the same string and
6875 is empty. (Bug#9739) (Bug#9738)
6877 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6879 * doc.c (get_doc_string): Encode file name (bug#9735).
6881 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6883 * bidi.c (bidi_level_of_next_char):
6884 * xdisp.c (get_visually_first_element): Remove old incorrect
6885 comments regarding the Unicode Line Separator character.
6887 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6889 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6891 * alloc.c (Fgc_status): Do not access beyond zombies array
6892 boundary if nzombies > MAX_ZOMBIES.
6893 * alloc.c (dump_zombies): Add missing format specifier.
6895 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6897 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6898 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6900 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6901 Some packages use them to denote characters with modifiers.
6903 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6905 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6906 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6907 matching a pp-number. Rename parameter var to var1.
6909 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6911 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6913 2011-10-08 Glenn Morris <rgm@gnu.org>
6915 * callint.c (Fcall_interactively): Give a more explicit error for the
6916 'c' case with a non-character input. (Bug#8479)
6918 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6920 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6922 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6923 lines that are hscrolled on the left.
6925 * dispnew.c (buffer_posn_from_coords): Account for a possible
6926 presence of header-line. (Bug#4426)
6928 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6930 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6931 Don't advertise functionality which we discourage or doesn't work.
6933 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6935 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6936 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6937 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6938 this makes Emacs dump core during garbage collection on rare
6939 occasions. sizeof is obviously inferior to offsetof here, so
6940 stick with offsetof.
6941 (GC_POINTER_ALIGNMENT): New macro.
6942 (mark_memory): Omit 3rd (offset) arg; caller changed.
6943 Don't assume EMACS_INT alignment is the same as pointer alignment.
6945 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6947 * keyboard.c (read_key_sequence_remapped): New var.
6948 (read_key_sequence): Compute remapping in the right buffer.
6949 (command_loop_1): Use read_key_sequence's remapping directly.
6951 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6953 * dired.c (file_name_completion): Don't expand file name.
6954 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6955 before checking file name handler.
6957 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6958 they've been requested explicitly (bug#9591).
6960 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6962 * keymap.c (Fsingle_key_description): Use make_specified_string
6963 instead of build_string to build string from push_key_description.
6966 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6968 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6969 This fixes a Y2038 bug on 64-bit hosts.
6970 * buffer.c (reset_buffer):
6971 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6972 (Fclear_buffer_auto_save_failure):
6973 Use 0, not -1, to represent an unset failure time, since time_t
6974 might not be signed.
6976 Remove dependency on glibc malloc internals.
6977 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6978 Move back here from lisp.h, but with their new implementations.
6979 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6980 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6981 * charset.c (charset_table_init): New static var.
6982 (syms_of_charset): Use it instead of xmalloc. This removes a
6983 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6984 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6985 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6986 Move back to alloc.c.
6987 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6988 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6990 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6992 * nsterm.m (windowDidResize): Call x_set_window_size only when
6993 ns_in_resize is true. Otherwise set pixelwidth/height and
6994 call change_frame_size (Bug#9628).
6996 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6998 Port --enable-checking=all to Fedora 14 x86-64.
6999 * charset.c (syms_of_charset): Also account for glibc malloc's
7000 internal overhead when calculating the initial malloc maximum.
7002 Port --enable-checking=all to Fedora 14 x86.
7003 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7005 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7006 (overrun_check_realloc, overrun_check_free):
7007 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7008 That way, xmalloc returns a properly-aligned pointer even if
7009 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7010 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7011 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7012 into account when calculating the initial malloc maximum.
7013 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7014 Move here from alloc.c, so that charset.c can use it too.
7015 Properly align; the old code wasn't right for common 32-bit hosts
7016 when configured with --enable-checking=all.
7017 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7018 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7020 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7022 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7025 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7027 * xdisp.c (compute_display_string_end): If there's no display
7028 string at CHARPOS, return -1.
7030 * bidi.c (bidi_fetch_char): When compute_display_string_end
7031 returns a negative value, treat the character as a normal
7032 character not covered by a display string. (Bug#9624)
7034 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7036 * lread.c (Fread_from_string): Fix typo in docstring.
7038 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7040 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7041 newline, reseat the iterator instead of bidi-iterating there one
7042 character at a time. (Bug#9610)
7043 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7044 TO_CHARPOS if the bidi iterator is at base embedding level.
7046 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7048 * lread.c (readevalloop): Use correct code for NBSP.
7049 (read1): Likewise. (Bug#9608)
7051 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7053 * dbusbind.c (Fdbus_register_signal): When service is not
7054 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7056 2011-09-25 Glenn Morris <rgm@gnu.org>
7058 * buffer.c (truncate-lines): Doc fix.
7060 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7062 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7063 (Fset_window_next_buffers): Doc fix.
7065 2011-09-24 Glenn Morris <rgm@gnu.org>
7067 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7069 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7071 Fix minor problems found by static checking.
7072 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7073 * indent.c (Fvertical_motion): Fix == vs = typo.
7075 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7077 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7078 Default value is now t. Doc fix.
7080 * indent.c (Fvertical_motion): Compute and apply the overshoot
7081 logic when moving up, not only when moving down. Fix the
7082 confusing name and values of the it_overshoot_expected variable;
7083 logic changes accordingly. (Bug#9254) (Bug#9549)
7085 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7086 CHARPOS is covered by a display string which includes newlines.
7087 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7088 is covered by a display string with embedded newlines.
7090 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7092 * dbusbind.c (Fdbus_register_signal): Add match rule to
7093 Vdbus_registered_objects_table. (Bug#9581)
7094 (Fdbus_register_method, Vdbus_registered_objects_table):
7097 2011-09-24 Jim Meyering <meyering@redhat.com>
7099 do not ignore write error for any output size
7100 The previous change was incomplete.
7101 While it makes emacs --batch detect the vast majority of stdout
7102 write failures, errors were still ignored whenever the output size is
7103 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7104 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7105 && echo FAIL: ignored write error
7106 FAIL: ignored write error
7107 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7108 && echo FAIL: ignored write error
7109 FAIL: ignored write error
7110 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7112 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7114 * emacs.c (Fkill_emacs): In noninteractive mode exit
7115 non-successfully if a write error occurred on stdout. (Bug#9574)
7117 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7119 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7122 * dispextern.h (struct it): Update the comment documenting what
7125 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7127 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7128 a display string, extend search for cursor position to end of row.
7129 (find_row_edges): If the row ends in a newline from a display
7130 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7131 Handle the case of a display string with multiple newlines.
7132 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7133 non-empty line. Fixes confusing cursor motion with arrow keys at
7134 the beginning of a line that starts with whitespace.

7138 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7141 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7143 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7146 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7148 * xdisp.c (display_line): Record maximum and minimum buffer
7149 positions even if no glyphs were produced (e.g., by a zero-width
7150 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7151 buffer positions that will be removed from the glyph row because
7153 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7154 column is beyond frame width: don't subtract 1 "pixel" when
7155 computing width of the stretch.
7156 (reseat_at_next_visible_line_start): Undo the change made on
7157 2011-09-17 that saved paragraph information and restored it after
7158 the call to `reseat'. (Bug#9545)
7160 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7162 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7163 and turn window cursor on if cleared (Bug#9415).

7174 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7176 Fix minor problem found by static checking.
7177 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7178 initialized, to pacify gcc -Wuninitialized.
7180 * fileio.c: Report proper errno when syscall falls.
7181 (Finsert_file_contents): Save and restore errno,
7182 so that report_file_error outputs the correct diagnostic.
7183 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7185 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7187 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7189 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7191 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7192 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7194 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7196 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7197 about the current paragraph and restore it after the call to reseat.
7199 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7200 (bidi_find_paragraph_start): Search back for paragraph beginning
7201 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7202 (bidi_move_to_visually_next): Only trigger paragraph-related
7203 computations when the last character is a newline or at EOB, not
7204 just any NEUTRAL_B. (Bug#9470)
7206 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7207 truncated lines if point is covered by a display string. (Bug#9524)
7209 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7211 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7212 (cons_to_x_long): New function.
7213 (lisp_data_to_selection_data): Use it. Correct the test for
7214 short-versus-long data; it was negated. Break out of vector
7215 loop, for efficiency, when a long datum is discovered.
7217 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7219 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7221 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7223 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7224 GCC PR/17406) by declaring this function with external scope.
7226 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

7247 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7248 This occurs when processing a multibyte format.
7249 Problem reported by Wolfgang Jenker.
7251 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7253 * xdisp.c (try_cursor_movement): Only check for exact match if
7254 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7256 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7258 Remove unused external symbols.
7259 * dispextern.h (calc_pixel_width_or_height): Remove decl.

7261 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7262 * indent.c (check_display_width):
7263 * w32term.c: Fix comment to match code.
7264 * xterm.c, xterm.h (x_catching_errors): Remove.
7266 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7268 * xselect.c: Use signed conversions more consistently (Bug#9498).
7269 (selection_data_to_lisp_data): Assume incoming selection data are
7270 signed integers, not unsigned. This is to be consistent with
7271 outgoing selection data, which was modified to use signed integers
7272 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7273 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7274 expects long, not unsigned long.
7276 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7278 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7279 computation of loop end. Reported by Johan Bockgård
7282 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7284 * frame.c (Fother_visible_frames_p): Function deleted.
7286 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7288 * indent.c (compute_motion): Process display vector front to back
7289 rather than the other way around. (Bug#2496)
7291 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7293 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7295 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7297 * minibuf.c (Fread_from_minibuffer): Doc fix.
7299 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7301 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7302 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7304 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7306 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7307 value for non-existent files.
7309 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7311 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7312 set its "size" to -1. This will set the modtime_size field of
7313 the corresponding buffer to -1, which is what
7314 verify-visited-file-modtime expects for files that do not exist.
7317 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7319 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7321 * lisp.h: ... from here. push_key_description is no longer
7322 defined in keyboard.c, so its declaration should not be in
7323 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7324 logically belongs with push_key_description.
7326 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7328 * buffer.h: Include <sys/types.h> instead of <time.h>.
7329 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7330 Problem reported by Herbert J. Skuhra.
7332 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7334 * xml.c (parse_region): Make the parsing work for
7335 non-comment-starting XML files again (bug#9144).
7337 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7339 * image.c (gif_load): Fix calculation of bottom and right corner.
7342 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7344 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7345 redisplay in small windows.
7347 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7349 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7351 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7353 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7354 Operate on live windows only.
7356 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7358 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7360 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7362 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7363 only under bidi iteration.
7365 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7367 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7369 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7371 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7372 Without this fix, the command to link temacs failed due to an
7373 undefined symbol __builtin_isnan. This is because
7374 /usr/include/iso/math_c99.h #defines isnan(x) to
7375 __builtin_isnan(x), but the bundled gcc, which identifies itself
7376 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7378 * floatfns.c (isnan): #undef, and then #define to a clone of
7380 (Fisnan): Always define, since it's always available now.
7381 (syms_of_floatfns): Always define isnan at the Lisp level.
7383 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7385 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7387 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7389 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7390 The previous code assumed that file offsets (off_t values) fit in
7391 EMACS_INT variables, which is not true on typical 32-bit hosts.
7392 The code messed up by falsely reporting buffer overflow in cases
7393 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7394 when "big" contains more than 2**29 bytes, even though this
7395 inserts just one byte and does not overflow the buffer.
7396 (Finsert_file_contents): Store file offsets as off_t
7397 values, not as EMACS_INT values. Check for overflow when
7398 converting between EMACS_INT and off_t. When checking for
7399 buffer overflow or for overlap, take the offsets into account.
7400 Don't use EMACS_INT for small values where int suffices.
7401 When checking for overlap, fix a typo: ZV was used where
7402 ZV_BYTE was intended.
7403 (Fwrite_region): Don't assume off_t fits into 'long'.
7404 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7406 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7408 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7410 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7412 sprintf-related integer and memory overflow issues (Bug#9412).
7414 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7415 (esprintf, exprintf, evxprintf): New functions.
7416 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7417 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7418 (modify_event_symbol): Do not assume that the length of
7419 name_alist_or_stem is safe to alloca and fits in int.
7420 (Fexecute_extended_command): Likewise for function name and binding.
7421 (Frecursion_depth): Wrap around reliably on integer overflow.
7422 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7423 since some callers pass EMACS_INT values.
7424 (Fsingle_key_description): Don't crash if symbol name contains more
7425 than MAX_ALLOCA bytes.
7426 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7427 (get_minibuffer): Arg is now EMACS_INT, not int.
7428 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7429 (esprintf, exprintf, evxprintf): New decls.
7430 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7432 * dbusbind.c (signature_cat): New function.
7433 (xd_signature, Fdbus_register_signal):
7434 Do not overrun buffer; instead, report string overflow.
7436 * dispnew.c (add_window_display_history): Don't overrun buffer.
7437 Truncate instead; this is OK since it's just a log.
7439 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7440 even if the time zone offset is outlandishly large.
7441 Don't mishandle offset == INT_MIN.
7443 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7444 when creating daemon; the previous buffer-overflow check was incorrect.
7446 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7447 which has the guts of the old verror function.
7449 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7450 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7452 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7453 (font_unparse_xlfd): Don't blindly alloca long strings.
7454 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7455 fits in int, when using sprintf. Use single snprintf to count
7456 length of string rather than counting it via multiple sprintfs;
7457 that's simpler and more reliable.
7458 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7459 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7460 sprintf, in case result does not fit in int.
7462 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7463 (fontset_from_font): Print it.
7465 * frame.c (tty_frame_count): Now printmax_t, not int.
7466 (make_terminal_frame, set_term_frame_name): Print it.
7467 (x_report_frame_params): In X, window IDs are unsigned long,
7468 not signed long, so print them as unsigned.
7469 (validate_x_resource_name): Check for implausibly long names,
7470 and don't assume name length fits in 'int'.
7471 (x_get_resource_string): Don't blindly alloca invocation name;
7472 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7475 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7476 (xg_check_special_colors, xg_set_geometry):
7477 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7479 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7480 Use esprintf, not sprintf, in case result does not fit in int.
7482 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7483 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7484 it as a large positive number.
7485 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7486 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7488 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7489 in case result does not fit in int.
7491 * print.c (float_to_string): Detect width overflow more reliably.
7492 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7493 buffer overrun. Don't assume list length fits in 'int'. Treat
7494 print length of 0 as 0, not as infinity; to be consistent with other
7495 uses of print length in this function. Don't overflow print length
7496 index. Don't assume hash table size fits in 'long', or that
7497 vectorlike size fits in 'unsigned long'.
7499 * process.c (make_process): Use printmax_t, not int, to format
7500 process-name gensyms.
7502 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7504 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7505 to avoid potential buffer overrun.
7507 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7508 if X resource line is longer than 512 bytes.
7510 * xfns.c (x_window): Make sprintf buffer a bit bigger
7511 to avoid potential buffer overrun.
7513 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7515 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7517 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7519 Integer overflow fixes for scrolling, etc.
7520 Without these, Emacs silently mishandles large integers sometimes.
7521 For example, "C-u 4294967297 M-x recenter" was treated as if
7522 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7524 * xdisp.c (try_window_id): Check Emacs fixnum range before
7525 converting to 'int'.
7527 * window.c (window_scroll_line_based, Frecenter):
7528 Check that an Emacs fixnum is in range before assigning it to 'int'.
7529 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7530 values converted from Emacs fixnums.
7531 (Frecenter): Don't wrap around a line count if it is out of 'int'
7532 range; instead, treat it as an extreme value.
7533 (Fset_window_configuration, compare_window_configurations):
7534 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7536 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7537 that can exceed INT_MAX. Check that EMACS_INT value is in range
7538 before assigning it to the (possibly-narrower) index.
7539 (match_limit): Don't assume that a fixnum can fit in 'int'.
7541 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7544 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7545 (Fvertical_motion): Don't wrap around LINES values that don't fit
7546 in 'int'. Instead, treat them as extreme values. This is good
7547 enough for windows, which can't have more than INT_MAX lines anyway.
7549 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7551 * Require libxml/parser.h to avoid compilation warning.
7553 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7555 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7556 since this reportedly can destroy thread storage.
7558 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7560 * syntax.c (find_defun_start): Update all cache variables if
7561 exiting early (Bug#9401).
7563 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7565 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7567 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7568 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7569 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7571 * term.c (tty_append_glyph): New function.
7572 (produce_stretch_glyph): Static function and its prototype deleted.
7574 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7577 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7579 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7580 when checking :margin (Bug#9390).
7581 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7582 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7583 so that the name doesn't mislead. All uses changed.
7585 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7587 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7590 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7592 * xdisp.c (move_it_to): Don't bail out early when reaching
7593 position beyond to_charpos, if we are scanning backwards.
7594 (move_it_vertically_backward): When DY == 0, make sure we get to
7595 the first character in the line after the newline.
7597 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7599 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7600 (ccl_driver): Do not generate an out-of-range pointer.
7601 (Fccl_execute_on_string): Remove unnecessary check for
7602 integer overflow, noted by Stefan Monnier in
7603 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7604 Remove a FIXME that didn't need fixing.
7605 Simplify the newly-introduced buffer reallocation code.
7607 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7609 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7611 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7613 Integer and memory overflow issues (Bug#9196).
7615 * doc.c (get_doc_string): Rework so that
7616 get_doc_string_buffer_size is the actual buffer size, rather than
7617 being 1 less than the actual buffer size; this makes xpalloc more
7620 * image.c (x_allocate_bitmap_record, cache_image):
7621 * xselect.c (Fx_register_dnd_atom):
7622 Simplify previous changes by using xpalloc.
7624 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7625 since either will do and ptrdiff_t is convenient with xpalloc.
7627 * charset.c (charset_table_size)
7628 (struct charset_sort_data.priority): Now ptrdiff_t.
7629 (charset_compare): Don't overflow if priorities differ greatly.
7630 (Fsort_charsets): Don't assume list length fits in int.
7631 Check for size-calculation overflow when allocating sort data.
7632 (syms_of_charset): Allocate an initial charset table that is
7633 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7635 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7637 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7638 The actual value is always <= INT_MAX, and leaving it unsigned made
7639 overflow checking harder.
7641 * dispextern.h (struct glyph_matrix.rows_allocated)
7642 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7643 with xpalloc. The values are still always <= INT_MAX.
7645 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7647 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7648 (SAFE_NALLOCA): New macro.
7650 * region-cache.c (struct boundary.pos, find_cache_boundary)
7651 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7652 (set_cache_region, invalidate_region_cache)
7653 (revalidate_region_cache, know_region_cache, region_cache_forward)
7654 (region_cache_backward, pp_cache):
7655 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7656 so that ptrdiff_t * can be passed to xpalloc.
7657 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7658 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7659 (pp_cache): Don't assume cache_len fits in int.
7660 * region-cache.h: Adjust extern decls to match.
7662 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7663 EMACS_INT, since either will do, for xpalloc.
7665 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7666 (xnmalloc, xnrealloc, xpalloc): New functions.
7668 * bidi.c (bidi_shelve_header_size): New constant.
7669 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7670 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7672 * bidi.c (bidi_cache_shrink):
7673 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7675 Don't update size of array until after memory allocation succeeds,
7676 because xmalloc/xrealloc may not return.
7677 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7678 now that we have proper integer overflow checking.
7679 (record_overlay_string, overlay_strings): Catch overflows when
7680 calculating size of overlay_str_buf.
7682 * callproc.c (Fcall_process): Check for size overflow when
7683 calculating size of args2.
7684 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7685 Normally we prefer signed values, but sticking with ptrdiff_t would
7686 require adding more-complicated checks.
7688 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7689 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7690 Redo buffer-overflow calculations to avoid integer overflow.
7691 Add a FIXME comment where memory seems to be over-allocated.
7693 * character.c (Fstring): Check for size-calculation overflow.
7695 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7696 unnecessary integer overflow. Check for size overflow.
7697 (encode_coding_object): Don't update size until xmalloc succeeds.
7699 * composite.c (get_composition_id): Check for overflow in glyph
7700 length calculations.
7702 Integer and memory overflow fixes for display code.
7703 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7704 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7705 (scrolling_window): Check for overflow in size calculations.
7706 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7707 Don't assume glyph table len fits in int.
7708 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7709 (row_table_size): Now ptrdiff_t, not int.
7710 (scrolling_window): Avoid overflow in size calculations.
7711 Don't update size until allocation succeeds.
7712 * fns.c (concat): Check for overflow in size calculations.
7713 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
7714 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7715 (NEXT_ALMOST_PRIME_LIMIT): New constant.
7717 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7718 (get_doc_string): Check for size calculation overflow.
7719 Don't update size until allocation succeeds.
7720 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7721 EMACS_INT, where ptrdiff_t will do.
7722 (Fsubstitute_command_keys): Check for string overflow.
7724 * editfns.c (set_time_zone_rule): Don't assume environment length
7726 (message_length): Now ptrdiff_t, not int.
7727 (Fmessage_box): Don't update size until allocation succeeds.
7728 Don't assume message length fits in int.
7729 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7731 * emacs.c (main): Do not reallocate argv, since there is a null at
7732 the end that can be overwritten, and this way there's no need to
7733 worry about size-calculation overflow.
7734 (sort_args): Check for size-calculation overflow.
7736 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7738 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7740 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7741 (x_set_scroll_bar_width, x_figure_window_size):
7742 Check for integer overflow.
7743 (x_set_alpha): Do not assume XINT fits in int.

7851 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7852 sizes, since they can exceed INT_MAX in size. Check for size

7862 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7863 (X_LONG_MIN): New macros.
7864 Use them to make the following changes clearer.
7865 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7866 This change doesn't affect the value now, but it may help remind
7867 future maintainers not to raise the value too much later.
7868 (SELECTION_QUANTUM): Remove, replacing with ...
7869 (selection_quantum): ... new function, which avoids overflow.
7871 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

7889 Don't store size until memory allocation succeeds.
7890 (x_get_window_property): Plug memory leak on memory exhaustion.
7891 Don't double-block input; malloc is safe here. Don't assume 2**34
7892 - 4 fits in unsigned long. Add an xassert to check
7893 XGetWindowProperty overflow. Be more careful about overflow
7894 calculations, and distinguish size from memory overflow better.

7900 in the range -65535 through -1 fit in an X unsigned short.
7901 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7902 result parameters unless successful. Rely on cons_to_unsigned
7903 to report problems with elements; the old code wasn't right anyway.
7904 (x_check_property_data): Check for int overflow; we cannot use
7905 a wider type due to X limits.
7906 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7938 * lisp.h (hash_lookup, hash_put):
7939 * minibuf.c (Ftest_completion):
7940 Use ptrdiff_t for hash table indexes, not int (which is too
7941 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7942 32-bit --with-wide-int hosts).

7975 (x_send_scroll_bar_event): Likewise. Check that the size does not
7976 exceed limits imposed by XClientMessageEvent, as well as the usual
7977 ptrdiff_t and size_t limits.
7979 * keyboard.c: Overflow, signedness and related fixes.
7980 (make_lispy_movement): Use same integer type in forward decl
7981 that is used in the definition.
7982 (read_key_sequence, keyremap_step):
7983 Change bufsize argument back to int, undoing my 2011-03-30 change.
7984 We prefer signed types, and int is wide enough here.
7985 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7986 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7987 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7988 length, not size_t. Use ptrdiff_t for index, not int.
7989 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7990 possibility of integer overflow.

8017 (png_load, gif_load, svg_load_image):
8018 Prefer int to unsigned where either will do.
8019 (tiff_handler): New function, combining the cores of the
8020 old tiff_error_handler and tiff_warning_handler.
8021 This function is rewritten to use vsnprintf and thereby avoid
8022 stack buffer overflows. It uses only the features of vsnprintf
8023 that are common to both POSIX and native Microsoft.
8024 (tiff_error_handler, tiff_warning_handler): Use it.
8025 (tiff_load, gif_load, imagemagick_load_image):
8026 Don't assume :index value fits in 'int'.
8027 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

8029 the integer types that MagickCropImage accepts. Don't assume
8030 Vimagemagick_render_type has a nonnegative value. Don't assume
8031 size_t fits in 'long'.
8032 (gs_load): Use printmax_t to print the widest integers possible.

8050 accurately, and prefer exact match for point under bidi.
8051 Don't advance `row' beyond the last row of the window.
8053 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8054 into disp_prop; all users changed.
8056 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8072 positioning on the newline at EOL of R2L text within L2R
8073 paragraph, and vice versa.
8074 (try_cursor_movement): Check continued rows, in addition to
8075 continuation rows. Fixes unwarranted scroll when point enters a
8076 continued line of R2L text within an L2R paragraph, or vice versa.
8077 (cursor_row_p): Consider the case of point being equal to
8078 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8079 from the end of a short line to the beginning of a continued line

8107 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8108 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8109 candidate is selected by the mouse, and that candidate has a
8110 composed character under the mouse.
8112 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8113 coordinates reported by pos-visible-in-window-p for a composed

8124 composed buffer positions.
8126 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8128 * image.c (gif_load): Don't assume that each subimage has the same
8129 dimensions as the base image. Handle disposal method that is
8130 "undefined" by the gif spec (Bug#9335).
8132 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8134 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8139 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8140 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8141 from an Org mode buffer to a Speedbar frame.
8143 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8144 a composition, take its buffer position from IT->cmp_it.charpos.
8145 Fixes cursor positioning at the beginning of a line that begins
8146 with a composed character.
8148 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8150 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8151 character bidirectional type, use STRONG_L instead. Fixes crashes
8152 in a buffer produced by `describe-categories'.
8154 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8155 members before the level stack, so they would be saved and
8156 restored when copying iterator state. Fixes incorrect reordering
8157 around TABs covered by display properties.
8159 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8202 * bidi.c (bidi_initialize): Remove unused local.
8204 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8207 * biditype.h: Remove file.
8208 * makefile.w32-in ($(BLD)/bidi.$(O)):
8209 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8211 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8213 * chartab.c: Improve commentary for the uniprop_table API.
8215 * bidi.c (bidi_paragraph_init): Support zero value of
8216 bidi_ignore_explicit_marks_for_paragraph_level.
8217 (bidi_initialize): Use uniprop_table instead of including
8218 biditype.h and bidimirror.h.
8220 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8221 coordinates of the iterator when restoring from ppos_it.
8224 2011-08-14 Kenichi Handa <handa@m17n.org>
8226 * process.c (create_process): Call setup_process_coding_systems
8227 after the pid of the process is set to -1 (Bug#8162).
8229 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8231 * xdisp.c (move_it_in_display_line_to): Don't invoke
8232 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8233 ppos_it. Fixes vertical cursor motion when line beginning is
8234 covered by an image. (Bug#9296)
8236 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8238 * nsterm.h (ns_run_ascript): Declare.
8239 (NSAPP_DATA2_RUNASSCRIPT): Define.
8241 * nsfns.m (as_script, as_result, as_status): New static variables.
8242 (ns_run_ascript): New function.
8243 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8244 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8245 the event loop. Get status from as_status (Bug#7276).
8247 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8248 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8249 the event loop (Bug#7276).
8251 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8253 * gnutls.c (QCgnutls_bootprop_priority)
8254 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8255 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8256 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8257 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8258 (QCgnutls_bootprop_verify_hostname_error)
8259 (QCgnutls_bootprop_callbacks_verify): Rename from
8260 Qgnutls_bootprop_..., all uses changed.
8262 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8265 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8267 * xfaces.c (Qframe_set_background_mode): Now static.
8268 * dispextern.h (Qframe_set_background_mode): Remove decl.
8270 * process.c (Fnetwork_interface_info): Declare local only if needed.
8272 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8274 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8275 (Fnetwork_interface_list): Allocate in increments of bytes instead
8276 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8277 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8279 (struct ifflag_def): notrailers is smart on OSX.
8280 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8281 Get hardware address with getifaddrs if available.
8283 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8285 * xdisp.c (iterate_out_of_display_property): xassert that
8286 IT->position is set to within IT->object's boundaries. Break from
8287 the loop as soon as EOB is reached; avoids infloops in redisplay
8288 when IT->position is set up wrongly due to some bug.
8289 Set IT->current to match the bidi iterator unconditionally.
8290 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8291 entry. Force push_it to save on the stack the current
8292 buffer/string position, to be restored by pop_it. Fix flags in
8293 the iterator structure wrt the object coming from a display
8294 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8295 properties. (Bug#9284)
8297 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8299 * fontset.c (fontset_get_font_group): Add proper type checks.
8302 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8304 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
8305 and LC_VERSION_MIN_MACOSX.
8306 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8307 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8309 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8311 * xdisp.c (forward_to_next_line_start): Allow to use the
8312 no-display-properties-and-no-overlays under bidi display.
8313 Set disp_pos in the bidi iterator to avoid searches for display
8314 properties and overlays.
8316 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8318 * editfns.c (Fset_time_zone_rule): Document relationship with the
8321 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8322 the font entity extracted from the cache (Bug#8109).
8324 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8326 * composite.c (autocmp_chars): Don't reset point. That is done by
8327 restore_point_unwind (Bug#5984).
8329 2011-08-07 Juri Linkov <juri@jurta.org>
8331 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8332 to show the arg `TIME' instead of `TIMEVAL'.
8334 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8336 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8337 display property strides EOL and includes a newline, as in
8338 longlines-mode. (Bug#9254)
8339 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8340 word-wrap under bidirectional display. (Bug#9224)
8342 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8343 is non-zero, even if the data buffer is NULL. Fixes a crash in
8344 vertical-motion with longlines-mode. (Bug#9254)
8346 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8348 * bidi.c <bidi_cache_total_alloc>: Now static.
8349 (bidi_initialize): Initialize bidi_cache_total_alloc.
8351 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8354 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8355 amount allocated this far in `bidi_cache_total_alloc'.
8356 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8357 non-zero, only free the data buffer without restoring the cache
8358 contents. All callers changed.
8360 * dispextern.h (bidi_unshelve_cache): Update prototype.
8362 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8363 (move_it_in_display_line, move_it_to)
8364 (move_it_vertically_backward, move_it_by_lines): Replace the call
8365 to xfree to an equivalent call to bidi_unshelve_cache.
8366 (move_it_in_display_line_to): Fix logic of returning
8367 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8369 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8371 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8372 came from a string character with a `cursor' property. (Bug#9229)
8374 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8376 * Makefile.in (LIB_PTHREAD): New variable.
8377 (LIBES): Add LIB_PTHREAD (Bug#9216).
8379 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8380 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8382 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8384 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8386 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8388 * xterm.c (x_find_topmost_parent): New function.
8389 (x_set_frame_alpha): Find topmost parent window with
8390 x_find_topmost_parent and set the property there also (bug#9181).
8391 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8393 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8395 * callproc.c (Fcall_process): Avoid vfork clobbering
8396 the local vars buffer, coding_systems, current_dir.
8398 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8400 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8402 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8404 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8405 so that it is not optimized away.
8407 * xdisp.c (compute_display_string_pos): Remove unused local.
8409 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8411 Fix slow cursor motion and scrolling in large buffers with
8412 selective display, like Org Mode buffers. (Bug#9218)
8414 * dispextern.h (struct bidi_it): New member disp_prop_p.
8416 * xdisp.c: Remove one-slot cache of display string positions.
8417 (compute_display_string_pos): Accept an additional argument
8418 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8419 for a display string or property. If found, set DISP_PROP_P
8422 * bidi.c (bidi_fetch_char): Accept an additional argument
8423 DISP_PROP_P, and pass it to compute_display_string_pos.
8424 Only handle text covered by a display string if DISP_PROP_P is returned
8425 non-zero. All callers of bidi_fetch_char changed.
8427 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8429 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8431 2010-12-03 Don March <don@ohspite.net>
8433 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8434 last character M-[char] is translated to ESC [char] (bug#7541).
8436 2011-08-02 Kenichi Handa <handa@m17n.org>
8438 * lisp.h (uniprop_table): Extern it.
8440 * chartab.c (uniprop_table): Make it non-static.
8442 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8444 * xdisp.c (forward_to_next_line_start): Accept additional argument
8445 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8447 (reseat_at_next_visible_line_start): Use the bidi iterator state
8448 returned by forward_to_next_line_start to restore the state of
8449 it->bidi_it after backing up to previous newline. (Bug#9212)
8451 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8453 * regex.c (re_comp): Protoize.
8454 (re_exec): Fix return type.
8455 (regexec): Fix type of `ret'. (Bug#9203)
8457 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8459 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8460 This is needed if max-image-size is a floating-point number.
8462 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8464 * print.c (print_object): Print empty symbol as ##.
8466 * lread.c (read1): Read ## as empty symbol.
8468 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8470 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8471 setting frame foreground color (Bug#9175).
8472 (x_set_background_color): Likewise.
8474 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8475 contents (Bug#9176).
8476 (EmacsTooltip -init): Remove bezels and add shadows to
8479 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8480 or scroll bar (Bug#8470).
8482 * nsfont.m (nsfont_open): Remove assignment to voffset and
8483 unnecessary vars hshink, expand, hd, full_height, min_height.
8484 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8486 * nsterm.h (nsfont_info): Remove voffset field.
8488 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8490 Implement strike-through and overline on NextStep (Bug#8863).
8492 * nsfont.m (nsfont_open): Use underline position provided by font,
8493 instead of hard-coded value of 2.
8494 (nsfont_draw): Call ns_draw_text_decoration instead.
8496 * nsterm.h: Add declaration for ns_draw_text_decoration.
8498 * nsterm.m (ns_draw_text_decoration): New function for drawing
8499 underline, overline, and strike-through.
8500 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8501 ns_draw_text_decoration. Change treatment of cursor drawing to
8502 accommodate underlining, etc.
8504 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8506 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8509 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8511 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8512 Without this fix, if a signal arrives just after memory fills up,
8513 'malloc' might be invoked reentrantly.
8515 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8516 In other words, assume that every image size is allowed, on non-X
8517 hosts. This assumption is probably wrong, but it lets Emacs compile.
8519 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8521 * regex.c (re_iswctype): Convert return values to boolean.
8523 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8525 * xdisp.c (compute_display_string_pos): Don't use cached display
8526 string position if the buffer had its restriction changed.
8529 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8531 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8533 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8535 Integer signedness and overflow and related fixes. (Bug#9079)
8537 * bidi.c: Integer size and overflow fixes.
8538 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8539 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8540 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8541 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8542 (bidi_find_other_level_edge):
8543 Use ptrdiff_t instead of EMACS_INT where either will do.
8544 This works better on 32-bit hosts configured --with-wide-int.
8545 (bidi_cache_ensure_space): Check for size-calculation overflow.
8546 Use % rather than repeated addition, for better worst-case speed.
8547 Don't set bidi_cache_size until after xrealloc returns, because it
8549 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8550 (bidi_cache_ensure_space): Also check that the bidi cache size
8551 does not exceed that of the largest Lisp string or buffer. See Eli
8552 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8554 * alloc.c (__malloc_size_t): Remove.
8555 All uses replaced by size_t. See Andreas Schwab's note
8556 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8558 * image.c: Improve checking for integer overflow.
8559 (check_image_size): Assume that f is nonnull, since
8560 it is always nonnull in practice. This is one less thing to
8561 worry about when checking for integer overflow later.
8562 (x_check_image_size): New function, which checks for integer
8563 overflow issues inside X.
8564 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8565 This removes the need for a memory_full check.
8566 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8567 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8568 (xbm_read_bitmap_data): Change locals back to 'int', since
8569 their values must fit in 'int'.
8570 (xpm_load_image, png_load, tiff_load):
8571 Invoke x_create_x_image_and_pixmap earlier,
8572 to avoid much needless work if the image is too large.
8573 (tiff_load): Treat overly large images as if
8574 x_create_x_image_and_pixmap failed, not as malloc failures.
8575 (gs_load): Use x_check_image_size.
8577 * gtkutil.c: Omit integer casts.
8578 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8579 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8581 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8583 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8584 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8585 would wrongly return t on a 64-bit host.
8587 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8588 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8589 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8590 and therefore cause GCC to emit a bogus diagnostic in some cases.
8592 * image.c: Integer signedness and overflow and related fixes.
8593 This is not an exhaustive set of fixes, but it's time to
8594 record what I've got.
8595 (lookup_pixel_color, check_image_size): Remove redundant decls.
8596 (check_image_size): Don't assume that arbitrary EMACS_INT values
8597 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8598 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8599 (tiff_load, imagemagick_load_image):
8600 Check for overflow in size calculations.
8601 (x_create_x_image_and_pixmap): Remove unnecessary test for
8602 xmalloc returning NULL; that can't happen.
8603 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8604 (xpm_color_bucket): Use better integer hashing function.
8605 (xpm_cache_color): Don't possibly over-allocate memory.
8606 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8607 (gif_memory_source):
8608 Use ptrdiff_t, not int or size_t, to record sizes.
8609 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8610 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8611 either works, as we prefer signed integers.
8612 (tiff_read_from_memory, tiff_write_from_memory):
8613 Return tsize_t, not size_t, since that's what the TIFF API wants.
8614 (tiff_read_from_memory): Don't fail simply because the read would
8615 go past EOF; instead, return a short read.
8616 (tiff_load): Omit no-longer-needed casts.
8617 (Fimagemagick_types): Don't assume size fits into 'int'.
8619 Improve hashing quality when configured --with-wide-int.
8620 * fns.c (hash_string): New function, taken from sxhash_string.
8621 Do not discard information about ASCII character case; this
8622 discarding is no longer needed.
8623 (sxhash-string): Use it. Change sig to match it. Caller changed.
8624 * lisp.h: Declare it.
8625 * lread.c (hash_string): Remove, since we now use fns.c's version.
8626 The fns.c version returns a wider integer if --with-wide-int is
8627 specified, so this should help the quality of the hashing a bit.
8629 * emacs.c: Integer overflow minor fix.
8630 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8631 Define only if GNU_LINUX.
8632 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8634 * dispnew.c: Integer signedness and overflow fixes.
8635 Remove unnecessary forward decls, that were a maintenance hassle.
8636 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8638 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8639 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8640 (prepare_desired_row, line_draw_cost):
8641 Use int, not unsigned, where either works.
8642 (save_current_matrix, restore_current_matrix):
8643 Use ptrdiff_t, not size_t, where either works.
8644 (init_display): Check for overflow more accurately, and without
8645 relying on undefined behavior.
8647 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8648 Remove, replacing with the new symbols in lisp.h. All uses changed.
8649 * fileio.c (make_temp_name):
8650 * filelock.c (lock_file_1, lock_file):
8651 * xdisp.c (message_dolog):
8652 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8653 Use pMd etc. instead.
8654 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8655 replacing the pWIDE etc. symbols removed from editfns.c.
8657 * keyboard.h (num_input_events): Now uintmax_t.
8658 This is (very slightly) less likely to mess up due to wraparound.
8661 * buffer.c: Integer signedness fixes.
8662 (alloc_buffer_text, enlarge_buffer_text):
8663 Use ptrdiff_t rather than size_t when either will do, as we prefer
8666 * alloc.c: Integer signedness and overflow fixes.
8667 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8668 (__malloc_size_t): Default to size_t, not to int.
8669 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8670 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8671 Prefer ptrdiff_t to size_t when either would do, as we prefer
8673 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8674 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8675 Now const. Initialize with values that are in range even if char
8677 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8678 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8679 These functions do the right thing with sizes > 2**32.
8680 (check_depth): Now ptrdiff_t, not int.
8681 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8682 Adjust to new way of storing sizes. Check for size overflow bugs
8684 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8685 slightly wrong anyway, as it missed one instance of
8686 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8687 (refill_memory_reserve): Omit needless cast to size_t.
8688 (mark_object_loop_halt): Mark as externally visible.
8690 * xselect.c: Integer signedness and overflow fixes.
8691 (Fx_register_dnd_atom, x_handle_dnd_message):
8692 Use ptrdiff_t, not size_t, since we prefer signed.
8693 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8694 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8695 x_dnd_atoms_size and x_dnd_atoms_length.
8697 * doprnt.c: Prefer signed to unsigned when either works.
8699 * doprnt.c (doprnt):
8701 * xdisp.c (vmessage):
8702 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8703 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8704 prefer signed arithmetic to avoid comparison confusion.
8705 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8706 but is a bit tricky.
8708 Assume freestanding C89 headers, string.h, stdlib.h.
8709 * data.c, doprnt.c, floatfns.c, print.c:
8710 Include float.h unconditionally.
8711 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8712 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8713 * regex.c: Likewise for stddef.h, string.h.
8714 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8715 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8716 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8717 (STDC_HEADERS): Remove obsolete defines.
8718 * sysdep.c: Include limits.h unconditionally.
8720 Assume support for memcmp, memcpy, memmove, memset.
8721 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8722 * regex.c (memcmp, memcpy):
8723 Remove; we assume C89 now.
8725 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8726 (__malloc_safe_bcopy): Remove; no longer needed.
8728 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8729 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8730 well either way, and we prefer signed to unsigned.
8732 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8734 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8735 closes the connection while we're reading (bug#9182).
8737 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8739 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8740 are specified (Bug#9168).
8742 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8744 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8745 Found by GCC static checking and --with-wide-int on a 32-bit host.
8747 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8749 * xdisp.c (compute_display_string_pos): Fix logic of caching
8750 previous display string position. Initialize cached_prev_pos to
8751 -1. Fixes slow-down at the beginning of a buffer.
8753 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8755 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8756 for attrs[LFACE_FONTSET_INDEX].
8758 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8760 * xml.c (parse_region): Remove unused local
8761 that was recently introduced.
8763 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8765 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8766 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8768 * xdisp.c (move_it_in_display_line_to): Record the best matching
8769 position for TO_CHARPOS while scanning the line, and restore it on
8770 exit if none of the characters scanned was an exact match.
8771 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8772 when exact match is impossible due to invisible text, and the
8773 lines are truncated.
8775 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8777 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8780 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8782 Fix a significant slow-down of cursor motion with C-n, C-p,
8783 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8784 auto-repeat under bidi redisplay in fontified buffers.
8785 * xdisp.c (compute_stop_pos_backwards): New function.
8786 (next_element_from_buffer): Call compute_stop_pos_backwards to
8787 find a suitable prev_stop when we find ourselves before
8789 (reseat): Don't look for prev_stop, as that could mean a very long
8791 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8792 <cached_disp_overlay_modiff>: Cache for last found display string
8794 (compute_display_string_pos): Return the cached position if asked
8795 about the same buffer in the same area of character positions, and
8796 the buffer wasn't changed since the time the display string
8797 position was cached.
8799 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8801 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8802 is an integer, which is important for empty lines. (Bug#9149)
8804 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8806 * frame.c (Fmodify_frame_parameters): In tty case, update the
8807 default face if necessary (Bug#4238).
8809 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8811 * editfns.c (Fstring_to_char): No need to explain what a character
8812 is in the docstring (Bug#6576).
8814 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8816 * xml.c (parse_region): Make sure we always return a tree.
8818 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8820 * xml.c (parse_region): If a document contains only comments,
8823 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8825 * xml.c (make_dom): Return comments, too.
8827 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8830 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8831 and the surrounding thread.
8832 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8833 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8834 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8836 * s/openbsd.h (BROKEN_SIGIO): Define.
8837 * unexelf.c (unexec) [__OpenBSD__]:
8838 Don't update the .mdebug section of the Alpha COFF symbol table.
8840 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8842 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8845 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8847 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8848 This fixes some race conditions on the permissions of any newly
8851 * alloc.c (valid_pointer_p): Use pipe, not open.
8852 This fixes some permissions issues when debugging.
8854 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8855 If fchown fails to set both uid and gid, try to set just gid,
8856 as that is sometimes allowed. Adjust the file's mode to eliminate
8857 setuid or setgid bits that are inappropriate if fchown fails.
8859 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8861 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8862 to compare Lisp_Objects.
8863 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8864 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8865 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8867 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8869 * lread.c (read_integer): Unread even EOF character.
8870 (read1): Likewise. Properly record start position of symbol.
8872 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8873 symbol character follows.
8875 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8877 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8878 This works around a problem with the previous change to Fcopy_file.
8879 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8880 and without this change, GCC might complain about discarding
8881 fchown's return value.
8883 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8885 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8887 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8889 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8891 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8893 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8894 it's used from the C level.
8896 * process.c: Use the same condition for POLL_FOR_INPUT in both
8897 keyboard.c and process.c (bug#1858).
8899 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8901 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8902 (Fgnutls_boot): Use it.
8904 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8906 * doc.c (Fsubstitute_command_keys): Revert last change.
8908 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8910 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8911 quotes the next character, and doesn't affect other longer
8912 sequences (bug#8935).
8914 * lread.c (syms_of_lread): Clarify that is isn't only
8915 `eval-buffer' and `eval-defun' that's affected by
8916 `lexical-binding' (bug#8460).
8918 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8920 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8921 bidi redisplay when a line includes both an image and is truncated.
8923 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8925 Fix minor problems found by static checking.
8926 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8927 (elsz): Now a signed constant, not a size_t var. We prefer signed
8928 types to unsigned, to avoid integer comparison confusion. Without
8929 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8930 "cannot optimize loop, the loop counter may overflow", a symptom
8932 * indent.c (Fvertical_motion): Mark locals as initialized.
8933 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8935 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8937 * search.c (Fre_search_backward): Mention `case-fold-search' in
8938 all the re_search_* functions (bug#8138).
8940 * keyboard.c (Fopen_dribble_file): Document when the file is

8951 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8952 (reseat_to_string): Initialize bidi_it->string.s and
8953 bidi_it->string.schars.

8955 NULL (avoids a crash in bidi_paragraph_init).
8956 Initialize itb.string.lstring.
8957 (init_iterator): Call bidi_init_it only of a valid
8958 buffer position was specified. Initialize paragraph_embedding to
8960 (reseat_to_string): Initialize the bidi iterator.
8961 (display_string): If we need to ignore text properties of
8962 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8963 original value of -1 will not work with bidi.)
8964 (compute_display_string_pos): First arg is now struct
8965 `text_pos *'; all callers changed. Support display properties on
8967 (compute_display_string_end): Support display properties on Lisp
8969 (init_iterator, reseat_1, reseat_to_string): Initialize the
8970 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8971 when iterating on a string not from display properties).
8972 (compute_display_string_pos, compute_display_string_end):
8973 Fix calculation of the object to scan. Fixes an error when using
8975 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8976 base_level_stop; instead, set base_level_stop to BEGV.
8977 Fixes crashes in vertical-motion.
8978 (next_element_from_buffer): Improve commentary for when
8979 the iterator is before prev_stop.
8980 (init_iterator): Initialize bidi_p from the default value of
8981 bidi-display-reordering, not from buffer-local value. Use the
8982 buffer-local value only if initializing for buffer iteration.
8983 (handle_invisible_prop): Support invisible properties on strings
8984 that are being bidi-reordered.
8985 (set_iterator_to_next): Support bidi reordering of C strings and
8987 (next_element_from_string): Support bidi reordering of Lisp
8989 (handle_stop_backwards): Support Lisp strings as well.
8990 (display_string): Support display of R2L glyph rows.
8991 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8992 (init_iterator): Don't initialize it->bidi_p for strings
8994 (reseat_to_string): Initialize it->bidi_p for strings here.
8995 (next_element_from_string, next_element_from_c_string)
8996 (next_element_from_buffer): Add xassert's for correspondence
8997 between IT's object being iterated and it->bidi_it.string
8999 (face_before_or_after_it_pos): Support bidi iteration.
9000 (next_element_from_c_string): Handle the case of the first string
9001 character that is not the first one in the visual order.
9002 (get_visually_first_element): New function, refactored from common
9003 parts of next_element_from_buffer, next_element_from_string, and
9004 next_element_from_c_string.
9005 (tool_bar_lines_needed, redisplay_tool_bar)
9006 (display_menu_bar): Force left-to-right direction. Add a FIXME
9007 comment for making that be controlled by a user option.
9008 (push_it, pop_it): Save and restore the state of the
9009 bidi iterator. Save and restore the bidi_p flag.
9010 (pop_it): Iterate out of display property for string iteration as
9012 (iterate_out_of_display_property): Support iteration over strings.
9013 (handle_single_display_spec): Set up it->bidi_it for iteration
9014 over a display string, and call bidi_init_it.

9017 iterator for displaying display or overlay strings.
9018 (forward_to_next_line_start): Don't use the shortcut if
9020 (back_to_previous_visible_line_start): If handle_display_prop
9021 pushed the iterator stack, restore the internal state of the bidi
9022 iterator by calling bidi_pop_it same number of times.
9023 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9024 and we are bidi-iterating, don't decrement the iterator position;
9025 instead, set the first_elt flag in the bidi iterator, to produce
9027 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9028 (push_display_prop): xassert that we are iterating a buffer.
9029 (push_it, pop_it): Save and restore paragraph_embedding member.
9030 (handle_single_display_spec, next_overlay_string)
9031 (get_overlay_strings_1, reseat_1, reseat_to_string)
9032 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9033 correctly. Don't assume unibyte strings are not bidi-reordered.
9034 (compute_display_string_pos)
9035 (compute_display_string_end): Fix handling the case of C string.
9036 (push_it, pop_it): Save and restore from_disp_prop_p.
9037 (handle_single_display_spec, push_display_prop): Set the
9038 from_disp_prop_p flag.
9039 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9043 for verifying that the iterator position is in sync with the bidi
9045 (handle_single_display_spec, get_overlay_strings_1)
9046 (push_display_prop): Fix initialization of paragraph direction for
9047 string when that of the parent object is not yet determined.

9049 iterator with IT's position. (Bug#7616)
9050 (find_row_edges): If ROW->start.pos gives position
9051 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

9059 (try_scrolling, redisplay_window, display_line): Use them when
9060 saving a temporary copy of the iterator and restoring it back.
9061 (back_to_previous_visible_line_start, reseat_1)
9062 (init_iterator): Empty the bidi cache "stack".
9063 (move_it_in_display_line_to): If iterator ended up at
9064 EOL, but we never saw any buffer positions smaller than
9065 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9066 motion in bidi-reordered lines.
9067 (move_it_in_display_line_to): Record prev_method and prev_pos
9068 immediately before the call to set_iterator_to_next. Fixes cursor
9069 motion in bidi-reordered lines with stretch glyphs and strings
9070 displayed in margins. (Bug#8133) (Bug#8867)
9071 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9073 (pos_visible_p): Support positions in bidi-reordered lines.
9074 Save and restore bidi cache.
9076 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9077 (bidi_paragraph_info): Delete unused struct.
9078 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9079 (bidi_cache_start): New variable.

9085 (bidi_level_of_next_char, bidi_find_other_level_edge)
9086 (bidi_move_to_visually_next): Compare cache index with
9087 bidi_cache_start rather than with zero.
9088 (bidi_fetch_char): Accept new argument STRING; all callers
9089 changed. Support iteration over a string. Support strings with
9090 display properties. Support unibyte strings. Fix the type of
9091 `len' according to what STRING_CHAR_AND_LENGTH expects.
9092 (bidi_paragraph_init, bidi_resolve_explicit_1)
9093 (bidi_resolve_explicit, bidi_resolve_weak)

9104 initialized to valid values.
9105 (bidi_init_it): Don't initialize charpos and bytepos with invalid
9107 (bidi_level_of_next_char): Allow the sentinel "position" to pass
9108 the test for valid cached positions. Fix the logic for looking up
9109 the sentinel state in the cache. GCPRO the Lisp string we are
9111 (bidi_push_it, bidi_pop_it): New functions.
9112 (bidi_initialize): Initialize the bidi cache start stack pointer.
9113 (bidi_cache_ensure_space): New function, refactored from part of

9457 (clone_per_buffer_values): Don't assume that

9499 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9500 subseconds part to the entropy, as that's a bit more random.
9501 Prefer signed to unsigned, since the signedness doesn't matter and
9502 in general we prefer signed. When given a limit, use a
9503 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9504 latter isn't right if USE_2_TAGS_FOR_INTS.
9505 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9506 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9519 This is more efficient than Ffile_directory_p and avoids a minor race.

9523 * buffer.c (Foverlay_put): Say what the return value is
9526 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9530 error be more correct.
9532 * fns.c (Frequire): Remove the mention of the .gz files, since
9533 that's installation-specific, but keep the mention of

9549 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9651 * eval.c (struct backtrace): Simplify and port the data structure.
9652 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9653 signed bit field, as this assumption is not portable and it makes
9654 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9655 "char debug_on_exit : 1" as this is not portable either; instead,
9656 use the portable "unsigned int debug_on_exit : 1". Remove unused
9657 member evalargs. Remove obsolete comments about cc bombing out.

9821 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9823 Integer and buffer overflow fixes (Bug#8873).
9825 * print.c (printchar, strout): Check for string overflow.
9826 (PRINTPREPARE, printchar, strout):
9827 Don't set size unless allocation succeeds.
9829 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9830 for sizes. Check for string overflow more accurately.

9850 (Fload, openp, read_buffer_size, read1)
9851 (substitute_object_recurse, read_vector, read_list, map_obarray):

9865 (read_escape): Check for hex character overflow.
9867 2011-06-22 Leo Liu <sdl.web@gmail.com>
9869 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9870 Move to minibuffer.el.
9872 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9874 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9875 The following patches are for when GLYPH_DEBUG && !XASSERT.
9876 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9877 * dispnew.c (flush_stdout):
9878 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9879 Mark as externally visible.
9880 * dispnew.c (check_window_matrix_pointers): Now static.
9881 * dispnew.c (window_to_frame_vpos):
9882 * xfns.c (unwind_create_frame):

9887 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9888 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9889 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9891 (debug_method_add): Use va_list and vsprintf rather than relying
9892 on undefined behavior with wrong number of arguments.
9893 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9894 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9895 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9896 since we're not interested in debugging glyphs with old libraries.
9897 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9898 GCC 4.6.0's static checking.
9900 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9902 Integer overflow and signedness fixes (Bug#8873).

9914 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9916 * xfaces.c (load_pixmap):
9917 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9918 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9919 (.bitmaps_last, struct x_output.icon_bitmap):
9920 Use ptrdiff_t, not int, for bitmap indexes.
9921 (x_allocate_bitmap_record): Check for size overflow.

9939 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9940 (x_session_initialize): Do not assume string length fits in int.
9942 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9943 This is unlikely, but can occur if DPI is outlandish.
9945 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9946 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9948 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9949 * xrdb.c (magic_file_p, search_magic_path):
9950 Omit last arg SUFFIX; it was always 0. All callers changed.
9951 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9953 * xfont.c (xfont_match): Avoid need for strlen.
9955 * xfns.c: Don't assume strlen fits in int.

9958 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9959 not unsigned long, as we prefer signed integers. All callers changed.
9960 Detect integer overflow in repeat count.
9961 (message_dolog): Don't assume print length fits in 39 bytes.
9962 (display_mode_element): Don't assume strlen fits in int.
9964 * termcap.c: Don't assume sizes fit in int and never overflow.
9965 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9966 (gobble_line): Check for size-calculation overflow.
9968 * minibuf.c (Fread_buffer):
9969 * lread.c (intern, intern_c_string):
9970 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9971 Don't assume string length fits in int.

9983 * filelock.c: Fix some buffer overrun and integer overflow issues.
9984 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9985 Reformulate so as not to need the command string.
9986 Invoke gzip -cd rather than gunzip, as it's more portable.
9987 (lock_info_type, lock_file_1, lock_file):
9988 Don't assume pid_t and time_t fit in unsigned long.
9989 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9990 (current_lock_owner): Prefer signed type for sizes.
9991 Use memcpy, not strncpy, where memcpy is what is really wanted.
9992 Don't assume (via atoi) that time_t and pid_t fit in int.
9993 Check for time_t and/or pid_t out of range, e.g., via a network share.
9994 Don't alloca where an auto var works fine.
9996 * fileio.c: Fix some integer overflow issues.
9997 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9998 Don't assume string length fits in int.
9999 (directory_file_name): Don't assume string length fits in long.

10003 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10005 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10007 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

10021 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10023 * lread.c (invalid_syntax): Omit length argument.
10024 All uses changed. This doesn't fix a bug, but it simplifies the
10025 code away from its former Hollerith-constant appearance, and it's
10026 one less 'int' to worry about when looking at integer-overflow issues.
10027 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10029 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10030 This didn't break anything, but it didn't help either.
10031 It's confusing to put a bogus integer in a place where the actual
10032 value does not matter.
10033 (LIST_END_P): Remove unused macro and its bogus comment.
10034 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10036 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10037 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10039 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10040 We prefer signed types, and the value cannot exceed the EMACS_INT
10041 range anyway (because otherwise the length would not be representable).
10042 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10043 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10044 This avoids a GCC warning when WIDE_EMACS_INT.
10046 * indent.c (sane_tab_width): New function.
10047 (current_column, scan_for_column, Findent_to, position_indentation)
10048 (compute_motion): Use it. This is just for clarity.
10049 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10051 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10053 * lisp.h (lint_assume): New macro.
10054 * composite.c (composition_gstring_put_cache):
10055 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10057 * editfns.c, insdel.c:
10058 Omit unnecessary forward decls, to simplify future changes.
10060 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10062 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10064 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10065 Use much-faster test for byte-length change.
10066 Don't assume string byte-length fits in 'int'.
10067 Check that character arg fits in 'int'.
10068 (mapcar1): Declare byte as byte, for clarity.
10070 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10072 * fns.c (concat): Catch string overflow earlier.
10073 Do not rely on integer wraparound.
10075 * dispextern.h (struct it.overlay_strings_charpos)
10076 (struct it.selective): Now EMACS_INT, not int.
10077 * xdisp.c (forward_to_next_line_start)
10078 (back_to_previous_visible_line_start)
10079 (reseat_at_next_visible_line_start, next_element_from_buffer):
10080 Don't arbitrarily truncate the value of 'selective' to int.
10082 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10084 * composite.c: Don't truncate sizes to 'int'.
10085 (composition_gstring_p, composition_reseat_it)
10086 (composition_adjust_point): Use EMACS_INT, not int.
10087 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10088 not EMACS_UINT, for indexes.
10090 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10092 * buffer.c: Include <verify.h>.
10093 (struct sortvec.priority, struct sortstr.priority):
10094 Now EMACS_INT, not int.
10095 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10096 (struct sortstr.size, record_overlay_string)
10097 (struct sortstrlist.size, struct sortlist.used):
10098 Don't truncate size to int.
10099 (record_overlay_string): Check for size-calculation overflow.
10100 (init_buffer_once): Check at compile-time, not run-time.
10102 2011-06-22 Jim Meyering <meyering@redhat.com>
10104 Don't leak an XBM-image-sized buffer
10105 * image.c (xbm_load): Free the image buffer after using it.
10107 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10110 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10111 that Sun C diagnosed.
10112 * fns.c (secure_hash): Fix pointer signedness issue.
10113 * intervals.c (static_offset_intervals): New function.
10114 (offset_intervals): Use it.
10116 2011-06-21 Leo Liu <sdl.web@gmail.com>
10119 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10122 * fns.c (secure_hash): Rename from crypto_hash_function and change
10123 the first arg to accept symbols.
10124 (Fsecure_hash): New primitive.
10125 (syms_of_fns): New symbols.
10127 2011-06-20 Deniz Dogan <deniz@dogan.se>
10129 * process.c (Fset_process_buffer): Clarify return value in
10132 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10134 * dispnew.c (add_window_display_history): Use BVAR.
10136 * xdisp.c (debug_method_add): Use BVAR.
10137 (check_window_end, dump_glyph_matrix, dump_glyph)
10138 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10140 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10143 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10144 check till after the cache is created in init_frame_faces.
10146 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10148 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10150 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10152 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10153 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10154 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10156 Improve buffer-overflow checking (Bug#8873).
10157 * fileio.c (Finsert_file_contents):
10158 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10159 Remove the old (too-loose) buffer overflow checks.
10160 They weren't needed, since make_gap checks for buffer overflow.
10161 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10162 The old code merely checked for Emacs fixnum overflow, and relied
10163 on undefined (wraparound) behavior. The new code avoids undefined
10164 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10166 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10167 Tune. Don't use wider integers than needed. Don't use alloca.
10168 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10170 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10172 * insdel.c, lisp.h (buffer_overflow): New function.
10173 (insert_from_buffer_1, replace_range, replace_range_2):
10174 * insdel.c (make_gap_larger):
10175 * editfns.c (Finsert_char):
10176 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10178 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10180 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10182 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10184 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10185 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10187 * fileio.c: Don't assume EMACS_INT fits in off_t.
10188 (emacs_lseek): New static function.
10189 (Finsert_file_contents, Fwrite_region): Use it.
10190 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10192 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10194 * fns.c: Don't overflow int when computing a list length.
10195 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10196 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10197 truncation on 64-bit hosts. Check for QUIT every
10198 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10199 faster and is responsive enough.
10200 (Flength): Report an error instead of overflowing an integer.
10201 (Fsafe_length): Return a float if the value is not representable
10202 as a fixnum. This shouldn't happen except in contrived situations.
10203 (Fnthcdr, Fsort): Don't assume list length fits in int.
10204 (Fcopy_sequence): Don't assume vector length fits in int.
10206 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10207 (header_size, word_size): New constants.
10208 (allocate_vectorlike): Don't check size overflow here.
10209 (allocate_vector): Check it here instead, since this is the only
10210 caller of allocate_vectorlike that could cause overflow.
10211 Check that the new vector's length is representable as a fixnum.
10213 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10214 The previous code was bogus. For example, next_almost_prime (32)
10215 returned 39, which is undesirable as it is a multiple of 3; and
10216 next_almost_prime (24) returned 25, which is a multiple of 5 so
10217 why was the code bothering to check for multiples of 7?
10219 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10221 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10223 Variadic C functions now count arguments with ptrdiff_t.
10224 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10225 Back then I didn't know that the Emacs coding style prefers signed int.
10226 Also, in the meantime I found a few more instances where arguments
10227 were being counted with int, which may truncate counts on 64-bit
10228 machines, or EMACS_INT, which may be unnecessarily wide.
10229 * lisp.h (struct Lisp_Subr.function.aMANY)
10230 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10231 Arg counts are now ptrdiff_t, not size_t.
10232 All variadic functions and their callers changed accordingly.
10233 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10234 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10235 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10236 * callint.c (Fcall_interactively): Check arg count for overflow,
10237 to avoid potential buffer overrun. Use signed char, not 'int',
10238 for 'varies' array, so that we needn't bother to check its size
10239 calculation for overflow.
10240 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10241 * eval.c (apply_lambda):
10242 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10243 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10244 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10246 * callint.c (Fcall_interactively): Don't use index var as event count.
10248 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10249 * mem-limits.h (SIZE): Remove; no longer used.
10251 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10253 Remove unnecessary casts.
10254 * xterm.c (x_term_init):
10255 * xfns.c (x_set_border_pixel):
10256 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10257 These aren't needed now that we assume ANSI C.
10259 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10260 It's more likely to cause problems (due to unsigned overflow)
10263 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10265 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10267 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10269 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10271 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10273 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10275 GLYPH_CODE_FACE returns EMACS_INT, not int.
10276 * dispextern.h (merge_faces):
10277 * xfaces.c (merge_faces):
10278 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10279 Don't assume EMACS_INT fits in int.
10281 * character.h (CHAR_VALID_P): Remove unused parameter.
10282 * fontset.c, lisp.h, xdisp.c: All uses changed.
10284 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10286 * fns.c (concat): Minor tuning based on overflow analysis.
10287 This doesn't fix any bugs. Use int to hold character, instead
10288 of constantly refetching from Emacs object. Use XFASTINT, not
10289 XINT, for value known to be a character. Don't bother comparing
10290 a single byte to 0400, as it's always less.
10292 * floatfns.c (Fexpt):
10293 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10295 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10298 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10300 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10301 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10302 incorrectly succeed when S was a string, because 4294967386 was
10303 truncated before it was used.
10305 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10306 Otherwise, an out-of-range integer could cause undefined behavior
10309 * composite.c: Use int, not EMACS_INT, for characters.
10310 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10311 EMACS_INT, for values that are known to be in character range.
10312 This doesn't fix any bugs but is the usual style inside Emacs and
10313 may generate better code on 32-bit machines.
10315 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10316 This is for reasons similar to the recent CHAR_STRING fix.
10317 * charset.c (Fencode_char): Check that character arg is actually
10318 a character. Pass an int to ENCODE_CHAR.
10319 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10320 wider than 'int', as a compile-time check to prevent future regressions
10323 * character.c (char_string): Remove unnecessary casts.
10325 Make sure a 64-bit char is never passed to CHAR_STRING.
10326 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10327 by silently ignoring the top 32 bits, allowing some values
10328 that were far too large to be valid characters.
10329 * character.h: Include <verify.h>.
10330 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10331 arguments are no wider than unsigned, as a compile-time check
10332 to prevent future regressions in this area.
10334 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10335 (Fsubst_char_in_region):
10337 * xdisp.c (decode_mode_spec_coding):
10338 Adjust to CHAR_STRING's new requirement.
10339 * editfns.c (Finsert_char, Fsubst_char_in_region):
10340 * fns.c (concat): Check that character args are actually
10341 characters. Without this test, these functions did the wrong
10342 thing with wildly out-of-range values on 64-bit hosts.
10344 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10345 These casts should not be needed on 32-bit hosts, either.
10346 * keyboard.c (read_char):
10347 * lread.c (Fload): Remove casts to unsigned.
10349 * lisp.h (UNSIGNED_CMP): New macro.
10350 This fixes comparison bugs on 64-bit hosts.
10351 (ASCII_CHAR_P): Use it.
10352 * casefiddle.c (casify_object):
10353 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10354 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10355 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10356 * dispextern.h (FACE_FROM_ID):
10357 * keyboard.c (read_char): Use UNSIGNED_CMP.
10359 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10360 not to EMACS_INT, to avoid GCC warning.
10362 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10364 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10365 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10366 isn't needed on 32-bit machines.
10368 * buffer.c (Fgenerate_new_buffer_name):
10369 Use EMACS_INT for count, not int.
10370 (advance_to_char_boundary): Return EMACS_INT, not int.
10372 * data.c (Qcompiled_function): Now static.
10374 * window.c (window_body_lines): Now static.
10376 * image.c (gif_load): Rename local to avoid shadowing.
10378 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10379 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10380 * alloc.c (make_save_value): Integer argument is now of type
10381 ptrdiff_t, not int.
10382 (mark_object): Use ptrdiff_t, not int.
10383 * lisp.h (pD): New macro.
10384 * print.c (print_object): Use it.
10386 * alloc.c: Use EMACS_INT, not int, to count objects.
10387 (total_conses, total_markers, total_symbols, total_vector_size)
10388 (total_free_conses, total_free_markers, total_free_symbols)
10389 (total_free_floats, total_floats, total_free_intervals)
10390 (total_intervals, total_strings, total_free_strings):
10391 Now EMACS_INT, not int. All uses changed.
10392 (Fgarbage_collect): Compute overall total using a double, so that
10393 integer overflow is less likely to be a problem. Check for overflow
10394 when converting back to an integer.
10395 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10396 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10397 These were 'int' variables that could overflow on 64-bit hosts;
10398 they were never used, so remove them instead of repairing them.
10399 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10400 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10401 Previously, this ceilinged at INT_MAX, but that doesn't work on
10403 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10405 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10406 (allocate_vectorlike): Check for ptrdiff_t overflow.
10407 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10408 when a (possibly-narrower) signed value would do just as well.
10409 We prefer using signed arithmetic, to avoid comparison confusion.
10411 * alloc.c: Catch some string size overflows that we were missing.
10412 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10413 for convenience in STRING_BYTES_MAX.
10414 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10415 The definition here is exact; the one in lisp.h was approximate.
10416 (allocate_string_data): Check for string overflow. This catches
10417 some instances we weren't catching before. Also, it catches
10418 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10419 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10420 and ptrdiff_t and EMACS_INT are both 64 bits.
10422 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10423 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10424 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10426 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10428 * alloc.c (Fmake_string): Check for out-of-range init.
10430 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10432 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10434 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10436 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10437 xg_get_default_scrollbar_width.
10439 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10440 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10441 (style_changed_cb): Call update_theme_scrollbar_width and call
10442 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10443 all frames (Bug#8505).
10444 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10445 Call gtk_window_set_resizable if HAVE_GTK3.
10446 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10447 and height if HAVE_GTK3 (Bug#8505).
10448 (scroll_bar_width_for_theme): New variable.
10449 (update_theme_scrollbar_width): New function.
10450 (xg_get_default_scrollbar_width): Move code to
10451 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10452 (xg_initialize): Call update_theme_scrollbar_width.
10454 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10456 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10458 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10460 * frame.c (make_frame): Call other_buffer_safely instead of
10463 * window.c (temp_output_buffer_show): Call display_buffer with
10464 second argument Vtemp_buffer_show_specifiers and reset latter
10465 immediately after the call.
10466 (Vtemp_buffer_show_specifiers): New variable.
10467 (auto_window_vscroll_p, next_screen_context_lines)
10468 (Vscroll_preserve_screen_position): Remove leading asterisks from
10471 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10473 Fix minor problems found by GCC 4.6.0 static checking.
10474 * buffer.c (Qclone_number): Remove for now, as it's unused.
10475 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10476 (record_buffer): Remove unused local.

10920 (Fwindow_minibuffer_p): Move up in code and simplify.
10921 (Fset_frame_selected_window): Move here from frame.c.
10923 (Fselected_window, select_window, Fselect_window): Move up in
10924 code. Minor doc-string fixes.
10926 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
10928 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
10929 Do not assume that spare memory exists; that assumption is valid
10930 only if SYSTEM_MALLOC.
10931 (LARGE_REQUEST): New macro, so that the issue of large requests
10932 is separated from the issue of spare memory.
10934 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
10936 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

10953 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
10955 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
10957 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

10960 (x_clipboard_manager_save): Add return value.
10961 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
10962 New error handlers.
10963 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
10964 Obey Vx_select_enable_clipboard_manager. Catch errors in
10965 x_clipboard_manager_save (Bug#8779).
10966 (Vx_select_enable_clipboard_manager): New variable.
10967 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
10969 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
10971 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
10973 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10975 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
10976 in the current matrix if keep_current_p is non-zero.
10978 2011-06-04 Eli Zaretskii <eliz@gnu.org>
10980 * bidi.c (bidi_level_of_next_char): Fix last change.
10982 2011-06-03 Eli Zaretskii <eliz@gnu.org>
10984 Support bidi reordering of text covered by display properties.
10986 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
10987 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
10988 (bidi_cache_search, bidi_cache_iterator_state)
10989 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10990 (bidi_level_of_next_char, bidi_move_to_visually_next):
10991 Support character positions inside a run of characters covered by a
10993 (bidi_paragraph_init, bidi_resolve_explicit_1)
10994 (bidi_level_of_next_char): Call bidi_fetch_char and
10995 bidi_fetch_char_advance instead of FETCH_CHAR and
10996 FETCH_CHAR_ADVANCE.
10997 (bidi_init_it): Initialize new members.
10998 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11000 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11001 instead of using explicit *_CHAR codes.
11002 (bidi_resolve_explicit, bidi_resolve_weak):
11003 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11004 bidirectional text is supported only in multibyte buffers.
11005 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11006 it to initialize the frame_window_p member of struct bidi_it.
11007 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11008 (bidi_resolve_explicit, bidi_resolve_weak)

11010 bidi_it->nchars is non-positive.
11011 (bidi_level_of_next_char): Don't try to lookup the cache for the
11012 next/previous character if nothing is cached there yet, or if we
11013 were just reseat()'ed to a new position.
11015 * xdisp.c (set_cursor_from_row): Set start and stop points
11016 according to the row's direction when priming the loop that looks
11017 for the glyph on which to display cursor.
11018 (single_display_spec_intangible_p): Function deleted.
11019 (display_prop_intangible_p): Reimplement to call
11020 handle_display_spec instead of single_display_spec_intangible_p.
11021 Accept 3 additional arguments needed by handle_display_spec.
11022 This fixes incorrect cursor motion across display property with complex
11023 values: lists, `(when COND...)' forms, etc.
11024 (single_display_spec_string_p): Support property values that are
11025 lists with the argument STRING its top-level element.
11026 (display_prop_string_p): Fix the condition for processing a
11027 property that is a list to be consistent with handle_display_spec.
11028 (handle_display_spec): New function, refactored from the
11029 last portion of handle_display_prop.
11030 (compute_display_string_pos): Accept additional argument
11031 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11032 value of a `display' property is a "replacing spec".
11033 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11034 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11035 the display property, but just return a value indicating whether
11036 the display property will replace the characters it covers.
11037 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11038 frame_window_p members of struct bidi_it.
11039 (compute_display_string_pos, compute_display_string_end):
11041 (push_it): Accept second argument POSITION, where pop_it should
11042 jump to continue iteration.
11043 (reseat_1): Initialize bidi_it.disp_pos.
11045 * keyboard.c (adjust_point_for_property): Adjust the call to
11046 display_prop_intangible_p to its new signature.
11048 * dispextern.h (struct bidi_it): New member frame_window_p.
11049 (bidi_init_it): Update prototypes.
11050 (display_prop_intangible_p): Update prototype.
11051 (compute_display_string_pos, compute_display_string_end):
11052 Declare prototypes.
11053 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11056 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11058 Malloc failure behavior now depends on size of allocation.
11059 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11060 * lisp.h: Change signatures accordingly.
11061 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11062 All callers changed. (Bug#8762)
11064 * gnutls.c: Use Emacs's memory allocators.
11065 Without this change, the gnutls library would invoke malloc etc.
11066 directly, which causes problems on non-SYNC_INPUT hosts, and which
11067 runs afoul of improving memory_full behavior. (Bug#8761)
11068 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11069 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11070 xfree instead of the default malloc, realloc, free.
11071 (Fgnutls_boot): No need to check for memory allocation failure,
11072 since xmalloc does that for us.
11074 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11075 * category.c (hash_get_category_set):
11076 * ccl.c (ccl_driver):
11077 * charset.c (Fdefine_charset_internal):
11078 * charset.h (struct charset.hash_index):
11079 * composite.c (get_composition_id, gstring_lookup_cache)
11080 (composition_gstring_put_cache):
11081 * composite.h (struct composition.hash_index):
11082 * dispextern.h (struct image.hash):
11083 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11084 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11085 (hashfn_equal, hashfn_user_defined, make_hash_table)
11086 (maybe_resize_hash_table, hash_lookup, hash_put)
11087 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11088 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11089 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11090 * image.c (make_image, search_image_cache, lookup_image)
11091 (xpm_put_color_table_h):
11092 * lisp.h (struct Lisp_Hash_Table):
11093 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11094 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11095 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11096 * alloc.c (allocate_vectorlike):
11097 Check for overflow in vector size calculations.
11098 * ccl.c (ccl_driver):
11099 Check for overflow when converting EMACS_INT to int.
11100 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11101 need to be updated by these changes.
11102 * fns.c (make_hash_table, maybe_resize_hash_table):
11103 Check for integer overflow with large hash tables.
11104 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11105 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11106 (SXHASH_REDUCE): New macro.
11107 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11108 Use it instead of discarding useful hash info with large hash values.
11109 (sxhash_float): New function.
11110 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11111 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11112 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11113 Rewrite to use FIXNUM_BITS, as this simplifies things.
11114 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11115 Adjust signatures to match updated version of code.
11116 (consing_since_gc): Now EMACS_INT, since a single hash table can
11117 use more than INT_MAX bytes.
11119 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11121 Make it possible to build with GCC-4.6+ -O2 -flto.
11123 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11125 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11127 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11128 Call minibuffer-inactive-mode.
11130 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11132 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11133 Update dependencies.
11135 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11137 * data.c (init_data): Remove code for UTS, this system is not
11140 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11142 Don't force ./temacs to start in terminal mode.
11144 * frame.c (make_initial_frame): Initialize faces in all cases, not
11145 only when CANNOT_DUMP is defined.
11146 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11148 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11150 * dispnew.c (add_window_display_history): Use const for the string
11151 pointer. Remove declaration, not needed.
11153 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11155 Use 'inline', not 'INLINE'.
11156 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11157 * alloc.c, fontset.c (INLINE): Remove.
11158 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11159 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11160 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11161 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11162 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11164 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11166 Make it possible to run ./temacs.
11168 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11169 syms_of_callproc does the same thing. Remove test for
11170 "initialized", do it in the caller.
11171 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11173 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11175 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11176 (read_minibuf): Use get_minibuffer.
11177 (syms_of_minibuf): Use DEFSYM.
11178 (Qmetadata): New var.
11179 * data.c (Qbuffer): Don't make it static.
11180 (syms_of_data): Use DEFSYM.
11182 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11184 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11185 (CCL_CODE_MIN): New macro.
11187 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11189 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11191 * eval.c (Qdebug): Now static.
11192 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11193 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11194 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11196 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11198 * image.c: Various fixes to ImageMagick code comments.
11199 (Fimagemagick_types): Doc fix.
11201 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11203 Minor fixes prompted by GCC 4.6.0 warnings.
11205 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11207 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11208 (x_clipboard_manager_save_all): Move extern decl to ...
11209 * xterm.h: ... here, so that it can be checked for consistency.
11211 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11213 * xselect.c (x_clipboard_manager_save_frame)
11214 (x_clipboard_manager_save_all): New functions.
11215 (Fx_clipboard_manager_save): Lisp function deleted.
11217 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11218 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11220 * xterm.h: Update prototype.
11222 2011-05-28 William Xu <william.xwl@gmail.com>
11224 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11225 exiting (Bug#8239).
11227 2011-05-28 Jim Meyering <meyering@redhat.com>
11229 Avoid a sign-extension bug in crypto_hash_function.
11230 * fns.c (to_uchar): Define.
11231 (crypto_hash_function): Use it to convert some newly-signed
11232 variables to unsigned, to avoid sign-extension bugs. For example,
11233 without this change, (md5 "truc") would evaluate to
11234 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11235 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11236 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11238 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11240 Integer overflow fixes.
11242 * dbusbind.c: Serial number integer overflow fixes.
11243 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11244 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11245 to hold a serial number that is too large for a fixnum.
11246 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11247 Check for serial numbers out of range. Decode any serial number
11248 that was so large that it became a float. (Bug#8722)
11250 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11251 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11252 Use XFASTINT rather than XUINT when numbers are nonnegative.
11253 (xd_append_arg, Fdbus_method_return_internal):
11254 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11255 arguments, check that Lisp number is nonnegative, rather than
11256 silently wrapping negative numbers around. (Bug#8722)
11257 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11260 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11262 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11264 ccl: Add integer overflow checks.
11265 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11266 (IN_INT_RANGE): New macros.
11267 (ccl_driver): Use them to check for integer overflow when
11268 decoding a CCL program. Many of the new checks are whether XINT (x)
11269 fits in int; it doesn't always, on 64-bit hosts. The new version
11270 doesn't catch all possible integer overflows, but it's an
11271 improvement. (Bug#8719)
11273 * alloc.c (make_event_array): Use XINT, not XUINT.
11274 There's no need for unsigned here.
11276 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11277 This follows up to the 2011-05-06 change that substituted uintptr_t
11278 for EMACS_INT. This case wasn't caught back then.
11280 Rework Fformat to avoid integer overflow issues.
11281 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11282 now (part of C89). Include <verify.h>.
11283 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11284 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11285 (Fformat): Avoid the prepass trying to compute sizes; it was only
11286 approximate and thus did not catch overflow reliably. Instead, walk
11287 through the format just once, formatting and computing sizes as we go,
11288 checking for integer overflow at every step, and allocating a larger
11289 buffer as needed. Keep track separately whether the format is
11290 multibyte. Keep only the most-recently calculated precision, rather
11291 than them all. Record whether each argument has been converted to
11292 string. Use EMACS_INT, not int, for byte and char and arg counts.
11293 Support field widths and precisions larger than INT_MAX. Avoid
11294 sprintf's undefined behavior with conversion specifications such as %#d
11295 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11296 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11297 formatting out-of-range floating point numbers with int
11298 formats. (Bug#8668)
11300 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11302 * data.c: Avoid integer truncation in expressions involving floats.
11303 * data.c: Include <intprops.h>.
11304 (arith_driver): When there's an integer overflow in an expression
11305 involving floating point, convert the integers to floating point
11306 so that the resulting value does not suffer from catastrophic
11307 integer truncation. For example, on a 64-bit host (* 4
11308 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11309 Do not rely on undefined behavior after integer overflow.
11311 merge count_size_as_multibyte, parse_str_to_multibyte
11312 * character.c, character.h (count_size_as_multibyte):
11313 Rename from parse_str_to_multibyte; all uses changed.
11314 Check for integer overflow.
11315 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11316 since it's now a duplicate of the other. This is more of
11317 a character than a buffer op, so better that it's in character.c.
11318 * fns.c, print.c: Adjust to above changes.
11320 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11322 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11324 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11326 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11327 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11328 (x_clipboard_manager_save): Now static.
11329 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11331 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11332 (crypto_hash_function): Now static.
11333 Fix pointer signedness problems. Avoid unnecessary initializations.
11335 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11337 * termhooks.h (Vselection_alist): Make it terminal-local.
11339 * terminal.c (create_terminal): Initialize it.
11341 * xselect.c: Support for clipboard managers.
11342 (Vselection_alist): Move to termhooks.h as terminal-local var.
11343 (LOCAL_SELECTION): New macro.
11344 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11345 (symbol_to_x_atom): Remove gratuitous arg.
11346 (x_handle_selection_request, lisp_data_to_selection_data)
11347 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11348 (x_own_selection, x_get_local_selection, x_convert_selection):
11349 New arg, specifying work frame. Use terminal-local Vselection_alist.
11350 (some_frame_on_display): Delete unused function.
11351 (Fx_own_selection_internal, Fx_get_selection_internal)
11352 (Fx_disown_selection_internal, Fx_selection_owner_p)
11353 (Fx_selection_exists_p): New optional frame arg.
11354 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11355 (x_handle_selection_clear): Don't treat other terminals with the
11356 same keyboard specially. Use the terminal-local Vselection_alist.
11357 (x_clear_frame_selections): Use Frun_hook_with_args.
11359 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11361 * xterm.h: Add support for those atoms.
11363 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11365 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11366 (converted_selections, conversion_fail_tag): New global variables.
11367 (x_selection_request_lisp_error): Free the above.
11368 (x_get_local_selection): Remove unnecessary code.
11369 (x_reply_selection_request): Args changed; handle arbitrary array
11370 of converted selections stored in converted_selections.
11371 Separate the XChangeProperty and SelectionNotify steps.
11372 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11373 (x_convert_selection): New function.
11374 (x_handle_selection_event): Simplify.
11375 (x_get_foreign_selection): Don't ignore incoming requests while
11376 waiting for an answer; this will fail when we implement
11377 SAVE_TARGETS, and seems unnecessary anyway.
11378 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11379 (Vx_sent_selection_functions): Doc fix.
11381 2011-05-26 Leo Liu <sdl.web@gmail.com>
11383 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11385 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11387 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11389 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11390 for fringe update if it has periodic bitmap.
11391 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11392 and fringe_bitmap_periodic_p.
11394 * fringe.c (get_fringe_bitmap_data): New function.
11395 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11396 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11397 row. Mark glyph row for fringe update if periodicity changed.
11399 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11400 for fringe update unless it has periodic bitmap.
11402 2011-05-25 Kenichi Handa <handa@m17n.org>
11404 * xdisp.c (get_next_display_element): Set correct it->face_id for
11405 a static composition.
11407 2011-05-24 Leo Liu <sdl.web@gmail.com>
11410 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11412 * fns.c (crypto_hash_function, Fsha1): New function.
11413 (Fmd5): Use crypto_hash_function.
11414 (syms_of_fns): Add Ssha1.
11416 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11418 * gnutls.c: Remove unused macros.
11419 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11420 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11421 Remove macros that are defined and never used.
11422 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11424 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11426 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11427 (Fx_get_selection_internal): Minor cleanup.
11428 (Fx_own_selection_internal): Rename arguments for consistency with
11431 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11433 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11435 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11437 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11439 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11441 * dispnew.c (scrolling_window): Don't exclude the case that the
11442 last enabled row in the desired matrix touches the bottom boundary.
11444 2011-05-21 Glenn Morris <rgm@gnu.org>
11446 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11447 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11448 and add some more files.
11450 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11452 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11453 report_file_error introduced by the change from 2011-05-07.
11455 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11457 * systime.h (Time): Define only if emacs is defined.
11458 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11459 where the include path doesn't have X11/X.h by default. See
11460 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11462 2011-05-20 Kenichi Handa <handa@m17n.org>
11464 * composite.c (find_automatic_composition): Fix previous change.
11466 2011-05-20 Glenn Morris <rgm@gnu.org>
11468 * lisp.mk: New file, split from Makefile.in.
11469 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11470 (shortlisp): Remove.
11471 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11473 2011-05-19 Glenn Morris <rgm@gnu.org>
11475 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11476 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11477 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11478 (lisp): Set the order to that of loadup.el.
11479 (shortlisp): Make it a copy of $lisp.
11480 (SOME_MACHINE_LISP): Remove.
11481 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11482 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11484 2011-05-18 Kenichi Handa <handa@m17n.org>
11486 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11487 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11488 (find_automatic_composition): Mostly rewrite for efficiency.
11490 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11492 * makefile.w32-in: Update dependencies.
11494 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11496 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11497 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11499 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11501 Fix some integer overflow issues, such as string length overflow.
11503 * insdel.c (count_size_as_multibyte): Check for string overflow.
11505 * character.c (lisp_string_width): Check for string overflow.
11506 Use EMACS_INT, not int, for string indexes and lengths; in
11507 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11508 the resulting string length overflows an EMACS_INT; instead,
11509 report a string overflow if no precision given. When checking for
11510 precision exhaustion, use a check that cannot possibly have
11511 integer overflow. (Bug#8675)
11512 * character.h (lisp_string_width): Adjust to new signature.
11514 * alloc.c (string_overflow): New function.
11515 (Fmake_string): Use it. This doesn't change behavior, but saves
11516 a few bytes and will simplify future changes.
11517 * character.c (string_escape_byte8): Likewise.
11518 * lisp.h (string_overflow): New decl.
11520 Fixups, following up to the user-interface timestamp change.
11521 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11522 for UI timestamps, instead of unsigned long.
11523 * msdos.c (mouse_get_pos): Likewise.
11524 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11525 * w32gui.h (Time): Define by including "systime.h" rather than by
11526 declaring it ourselves. (Bug#8664)
11528 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11529 * image.c (clear_image_cache): Likewise.
11531 * term.c (term_mouse_position): Don't assume time_t wraparound.
11533 Be more systematic about user-interface timestamps.
11534 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11535 and sometimes 'EMACS_UINT', to represent these timestamps.
11536 This change causes it to use 'Time' uniformly, as that's what X uses.
11537 This makes the code easier to follow, and makes it easier to catch
11538 integer overflow bugs such as Bug#8664.
11539 * frame.c (Fmouse_position, Fmouse_pixel_position):
11540 Use Time, not unsigned long, for user-interface timestamps.
11541 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11542 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11543 * keyboard.h (last_event_timestamp): Likewise.
11544 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11545 * menu.h (xmenu_show): Likewise.
11546 * term.c (term_mouse_position): Likewise.
11547 * termhooks.h (struct input_event.timestamp): Likewise.
11548 (struct terminal.mouse_position_hook): Likewise.
11549 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11550 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11551 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11552 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11553 what it was before.
11554 * menu.h, termhooks.h: Include "systime.h", for Time.
11556 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11557 Don't assume that the difference between two unsigned long values
11558 can fit into an integer. At this point, we know button_down_time
11559 <= event->timestamp, so the difference must be nonnegative, so
11560 there's no need to cast the result if double-click-time is
11561 nonnegative, as it should be; check that it's nonnegative, just in
11562 case. This bug is triggered when events are more than 2**31 ms
11563 apart (about 25 days). (Bug#8664)
11565 * xselect.c (last_event_timestamp): Remove duplicate decl.
11566 (x_own_selection): Remove needless cast to unsigned long.
11568 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11569 that always fit in int. Use a sentinel instead of a counter, to
11570 avoid a temp and to allay GCC's concerns about possible int overflow.
11571 * frame.h (struct frame): Use int for menu_bar_items_used
11572 instead of EMACS_INT, since it always fits in int.
11574 * menu.c (grow_menu_items): Check for int overflow.
11576 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11578 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11579 Before, the code was not consistent. These values cannot exceed
11580 2**31 - 1 so there's no need to make them unsigned.
11581 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11582 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11583 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11585 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11587 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11588 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11589 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11590 presumably because the widths might not match.
11592 * window.c (size_window): Avoid needless test at loop start.
11594 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11596 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11598 2011-05-12 Drew Adams <drew.adams@oracle.com>
11600 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11602 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11604 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11605 `width' to `bar_area_x' and `bar_area_width', respectively.
11606 (x_scroll_run): Take account of fringe background extension.
11608 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11609 Rename local vars `left' and `width' to `bar_area_x' and
11610 `bar_area_width', respectively.
11611 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11612 background extension.
11614 2011-05-10 Jim Meyering <meyering@redhat.com>
11616 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11618 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11620 * image.c (Finit_image_library): Return t for built-in image types,
11621 like pbm and xbm. (Bug#8640)
11623 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11625 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11627 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11629 * w32console.c (Fset_screen_color): Doc fix.
11630 (Fget_screen_color): New function.
11631 (syms_of_ntterm): Defsubr it.
11633 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11634 unlink the temporary file if Fcall_process didn't create it in the
11636 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11637 child process will be redirected to a file specified with `:file'.
11638 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11639 cue to call_process_cleanup not to close that handle.
11641 2011-05-07 Ben Key <bkey76@gmail.com>
11643 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11644 one of two shell specific rules, either bootstrap-temacs-CMD or
11645 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11646 to the previous implementation of the bootstrap-temacs rule.
11647 The bootstrap-temacs-CMD rule is similar to the previous
11648 implementation of the bootstrap-temacs rule except that it
11649 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11652 These changes, along with some changes to nt/configure.bat,
11653 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11654 earlier fix to add support for --cflags and --ldflags options
11655 that include quotes so that it works whether make uses cmd or
11658 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11660 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11661 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11663 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11664 a string. Handle both cases.
11665 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11666 (Fdbus_register_method): Use Qinvalid_function.
11668 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11670 * makefile.w32-in: Update dependencies.
11671 (LISP_H): Add inttypes.h and stdin.h.
11672 (PROCESS_H): Add unistd.h.
11674 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11676 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11677 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11679 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11681 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11683 * term.c (vfatal): Remove stray call to va_end.
11684 It's not needed and the C Standard doesn't allow it here anyway.
11686 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11687 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11689 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11692 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11694 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11696 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11698 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11700 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11702 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11703 * charset.c (Fdefine_charset_internal): Don't initialize
11704 charset.code_space[15]. The value was garbage, on hosts with
11705 32-bit int (Bug#8600).
11707 * lread.c (read_integer): Be more consistent with string-to-number.
11708 Use string_to_number to do the actual conversion; this avoids
11709 rounding errors and fixes some other screwups. Without this fix,
11710 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11711 (digit_to_number): Move earlier, for benefit of read_integer.
11712 Return -1 if the digit is out of range for the base, -2 if it is
11713 not a digit in any supported base. (Bug#8602)
11715 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11717 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11718 to match comment at start of function. This also removes a
11719 GCC warning about overflow in a 32+64-bit port.
11721 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11723 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11724 Reported by Stefan Monnier in
11725 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11726 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11727 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11729 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11730 (EMACS_UINTPTR): Likewise, with uintptr_t.
11732 * lisp.h: Prefer 64-bit EMACS_INT if available.
11733 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11734 on 32-bit hosts that have 64-bit int, so that they can access
11736 However, temporarily disable this change unless the temporary
11737 symbol WIDE_EMACS_INT is defined.
11739 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11741 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11742 This removes an assumption that EMACS_INT and long are the same
11743 width as pointers. The assumption is true for Emacs porting targets
11744 now, but we want to make other targets possible.
11745 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11746 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11747 In the rest of the code, change types of integers that hold casted
11748 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11749 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11750 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11751 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11752 No need to cast type when ORing.
11753 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11754 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11755 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11756 assume EMACS_INT is the same width as char *.
11757 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11758 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11759 Remove no-longer-needed casts.
11760 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11761 (xg_tool_bar_help_callback, xg_make_tool_item):
11762 Use EMACS_INTPTR to hold an integer
11763 that will be cast to void *; this can avoid a GCC warning
11764 if EMACS_INT is not the same width as void *.
11765 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11766 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11767 (current_message_1, set_message_1):
11768 Use a local to convert to proper width without a cast.
11769 * xmenu.c (dialog_selection_callback): Likewise.
11771 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11772 Also, don't assume VALBITS / RAND_BITS is less than 5,
11773 and don't rely on undefined behavior when shifting a 1 left into
11775 * lisp.h (get_random): Change signature to match.
11777 * lread.c (hash_string): Use size_t, not int, for hash computation.
11778 Normally we prefer signed values; but hashing is special, because
11779 it's better to use unsigned division on hash table sizes so that
11780 the remainder is nonnegative. Also, size_t is the natural width
11781 for hashing into memory. The previous code used 'int', which doesn't
11782 retain enough info to hash well into very large tables.
11783 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11785 * dbusbind.c: Don't possibly lose pointer info when converting.
11786 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11787 Use XPNTR rather than XHASH, so that the high-order bits of
11788 the pointer aren't lost when converting through void *.
11790 * eval.c (Fautoload): Don't double-shift a pointer.
11792 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11794 2011-05-06 Juanma Barranquero <lekktu@gmail.com>

11801 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11804 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11806 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

11826 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11827 Remove unused parameter `fildes'.
11828 * process.c (read_process_output, send_process): Don't pass it.
11830 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11832 Fix previous change: the library cache is defined in w32.c.
11833 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11834 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

11854 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11855 (Fgnutls_available_p): New function.

11869 (w32_delayed_load): Move from image.c. When loading a library, record
11870 its filename in the :loaded-from property of the library id.
11871 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11872 Initialize and staticpro them.
11873 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11875 * process.c: Include lisp.h before w32.h, not after.
11876 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11877 instead of gnutls_record_check_pending.
11879 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11881 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11883 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11884 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11887 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11889 * xterm.c (x_set_frame_alpha): Do not set property on anything
11890 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11892 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11894 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11896 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11898 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

11924 (Fcall_process_region): Ditto.
11926 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11928 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11929 rather than `XVECTOR (FOO)->size'.
11931 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11932 inttypes.h, as a gnulib replacement is used if it not available in
11935 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11937 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11938 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11939 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11941 * coding.c (coding_alloc_by_realloc): Error out if destination
11942 will grow beyond MOST_POSITIVE_FIXNUM.
11943 (decode_coding_emacs_mule): Abort if there isn't enough place in
11944 charbuf for the composition carryover bytes. Reserve an extra
11945 space for up to 2 characters produced in a loop.

11947 charbuf for the composition carryover bytes.
11949 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11951 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11952 aborting when %lld or %lll format is passed.

11954 %llo or %llx format is passed. (Bug#8545)
11956 * window.c (window_scroll_line_based): Use a marker instead of
11957 simple variables to record original value of point. (Bug#7952)
11959 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11960 produced by %s or %c overflows available buffer space. (Bug#8545)
11962 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11964 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11965 (SIZE_MAX): Move defn after all includes, as they might #define it.
11967 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11969 * w32.c (init_environment): Warn about defaulting HOME to C:\.

11973 * keyboard.c (Qdelayed_warnings_hook): Define.
11974 (command_loop_1): Run `delayed-warnings-hook'
11975 if Vdelayed_warnings_list is non-nil.
11976 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11977 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11979 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11981 * doprnt.c (doprnt): Don't return value smaller than the buffer
11982 size if the message was truncated. (Bug#8545).

11986 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

11993 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11995 * makefile.w32-in: Update dependencies.
11997 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11999 Improve `doprnt' and its usage. (Bug#8545)
12000 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12001 `format_end'. Remove support for %l as a conversion specifier.
12002 Don't use xrealloc. Improve diagnostics when the %l size modifier
12003 is used. Update the commentary.
12005 * eval.c (verror): Simplify calculation of size_t.
12007 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12010 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12012 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12015 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12017 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12018 This makes this file independent of the recent pseudovector change.
12020 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12022 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12024 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12025 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12026 Remove unused local.
12027 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12029 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12030 GCC 4.6.0 optimizes based on type-based alias analysis.
12031 For example, if b is of type struct buffer * and v of type struct
12032 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12033 != &v->size, and therefore "v->size = 1; b->size = 2; return
12034 v->size;" must therefore return 1. This assumption is incorrect
12035 for Emacs, since it type-puns struct Lisp_Vector * with many other
12036 types. To fix this problem, this patch adds a new type struct
12037 vectorlike_header that documents the constraints on layout of vectors
12038 and pseudovectors, and helps optimizing compilers not get fooled
12039 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12040 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12041 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12043 (XSETPVECTYPE): Rewrite in terms of new macro.
12044 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12045 This is a bit clearer, and further avoids the possibility of
12046 undesirable aliasing.
12047 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12048 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12049 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12050 since Lisp_Subr is a special case (no "next" field).
12051 (ASIZE): Now uses header.size rather than size.
12052 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12053 to avoid the hassle of writing XVECTOR (foo)->header.size.
12054 (struct vectorlike_header): New type.
12055 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12056 object, to help avoid aliasing.
12057 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12058 (SUBRP): Likewise, since Lisp_Subr is a special case.
12059 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12060 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12061 (struct Lisp_Hash_Table): Combine first two members into a single
12062 struct vectorlike_header member. All uses of "size" and "next" members
12063 changed to be "header.size" and "header.next".
12064 * buffer.h (struct buffer): Likewise.
12065 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12066 * frame.h (struct frame): Likewise.
12067 * process.h (struct Lisp_Process): Likewise.
12068 * termhooks.h (struct terminal): Likewise.
12069 * window.c (struct save_window_data, struct saved_window): Likewise.
12070 * window.h (struct window): Likewise.
12071 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12072 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12073 * buffer.c (init_buffer_once): Likewise.
12074 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12076 * process.c (Fformat_network_address): Use local var for size,
12079 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12081 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12082 * data.c (atof): Remove decl; no longer used or needed.
12083 (digit_to_number): Move to lread.c.
12084 (Fstring_to_number): Use new string_to_number function, to be
12085 consistent with how the Lisp reader treats infinities and NaNs.
12086 Do not assume that floating-point numbers represent EMACS_INT
12087 without losing information; this is not true on most 64-bit hosts.
12088 Avoid double-rounding errors, by insisting on integers when
12089 parsing non-base-10 numbers, as the documentation specifies.
12090 * lisp.h (string_to_number): New decl, replacing ...
12091 (isfloat_string): Remove.
12092 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12093 (read1): Do not accept +. and -. as integers; this
12094 appears to have been a coding error. Similarly, do not accept
12095 strings like +-1e0 as floating point numbers. Do not report
12096 overflow for integer overflows unless the base is not 10 which
12097 means we have no simple and reliable way to continue.
12098 Break out the floating-point parsing into a new
12099 function string_to_number, so that Fstring_to_number parses
12100 floating point numbers consistently with the Lisp reader.
12101 (digit_to_number): Move here from data.c. Make it static inline.
12102 (E_CHAR, EXP_INT): Remove, replacing with ...
12103 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12104 (string_to_number): New function, replacing isfloat_string.
12105 This function checks for valid syntax and produces the resulting
12106 Lisp float number too. Rework it so that string-to-number
12107 no longer mishandles examples like "1.0e+". Use strtoumax,
12108 so that overflow for non-base-10 numbers is reported only when
12109 there's no portable and simple way to convert to floating point.
12111 * textprop.c (set_text_properties_1): Rewrite for clarity,
12112 and to avoid GCC warning about integer overflow.
12114 * intervals.h (struct interval): Use EMACS_INT for members
12115 where EMACS_UINT might cause problems. See
12116 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12117 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12118 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12120 (offset_intervals): Tell GCC not to worry about length overflow
12121 when negating a negative length.
12123 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12124 (overrun_check_free): Likewise.
12126 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12127 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12130 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12131 (gnutls_make_error): Rename local to avoid shadowing.
12132 (gnutls_emacs_global_deinit): ifdef out; not used.
12133 (Fgnutls_boot): Use const for pointer to readonly storage.
12134 Comment out unused local. Fix pointer signedness problems.
12136 * lread.c (openp): Don't stuff size_t into an 'int'.
12137 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12138 about possible signed overflow.
12140 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12141 (GDK_KEY_g): Don't define if already defined.
12142 (xg_prepare_tooltip): Avoid pointer signedness problem.
12143 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12145 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12146 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12148 * xfns.c (Fx_window_property): Simplify a bit,
12149 to make a bit faster and to avoid GCC 4.6.0 warning.
12150 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12152 * fns.c (internal_equal): Don't assume size_t fits in int.
12154 * alloc.c (compact_small_strings): Tighten assertion a little.
12156 Replace pEd with more-general pI, and fix some printf arg casts.
12157 * lisp.h (pI): New macro, generalizing old pEd macro to other
12158 conversion specifiers. For example, use "...%"pI"d..." rather
12159 than "...%"pEd"...".
12160 (pEd): Remove. All uses replaced with similar uses of pI.
12161 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12162 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12163 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12164 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12165 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12166 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12167 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12169 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12170 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12171 * print.c (safe_debug_print, print_object): Likewise.
12172 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12174 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12175 avoiding the 0 flag, which is not portable.
12176 * process.c (Fmake_network_process): Use pI to avoid cast.
12177 * region-cache.c (pp_cache): Likewise.
12178 * xdisp.c (decode_mode_spec): Likewise.
12179 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12180 behavior on 64-bit hosts with printf arg.
12181 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12182 (x_stop_queuing_selection_requests): Likewise.
12183 (x_get_window_property): Don't truncate byte count to an 'int'
12186 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12187 here, since it parses constructs like leading '-' and spaces,
12188 which are not wanted; and it overflows with large numbers.
12189 Instead, simply match F[0-9]+, which is what is wanted anyway.
12191 * alloc.c: Remove unportable assumptions about struct layout.
12192 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12193 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12194 (allocate_vectorlike, make_pure_vector): Use the new macros,
12195 plus offsetof, to remove unportable assumptions about struct layout.
12196 These assumptions hold on all porting targets that I know of, but
12197 they are not guaranteed, they're easy to remove, and removing them
12198 makes further changes easier.
12200 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12201 This doesn't fix a bug but makes the code clearer.
12202 (string_overrun_cookie): Now const. Use initializers that

12205 can cause Emacs to crash when string overrun checking is enabled.
12206 (allocate_buffer): Don't assume sizeof (struct buffer) is a

12377 to `error' in error message about FINAL_CHAR argument. Make sure
12378 FINAL_CHAR is a character, and use %c when it is passed as
12379 argument to `error'.
12381 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12383 * s/ms-w32.h (localtime): Redirect to sys_localtime.

12569 ns_descriptor_to_entity that were caused by using free to
12570 deallocate memory blocks that were allocated by xmalloc (via

12591 (emacs_read, emacs_write): Use it.
12592 * process.c (send_process): Adjust to the new signatures of
12593 emacs_write and emacs_gnutls_write. Do not attempt to store

13088 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13090 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13092 Fix more problems found by GCC 4.6.0's static checks.
13094 * xdisp.c (vmessage): Use a better test for character truncation.
13096 * charset.c (load_charset_map): <, not <=, for optimization,
13097 and to avoid potential problems with integer overflow.
13098 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13099 * casetab.c (set_identity, shuffle): Likewise.
13100 * editfns.c (Fformat): Likewise.
13101 * syntax.c (skip_chars): Likewise.
13103 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13104 This also lets GCC 4.6.0 generate slightly better loop code.
13106 * callint.c (Fcall_interactively): <, not <=, for optimization.
13107 (Fcall_interactively): Count the number of arguments produced,
13108 not the number of arguments given. This is simpler and lets GCC
13109 4.6.0 generate slightly better code.
13111 * ftfont.c: Distingish more carefully between FcChar8 and char.
13112 The previous code passed unsigned char * to a functions like
13113 strlen and xstrcasecmp that expect char *, which does not
13114 conform to the C standard.
13115 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13116 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13117 char * when the C standard requires it.
13119 * keyboard.c (read_char): Remove unused var.
13121 * eval.c: Port to Windows vsnprintf (Bug#8435).
13122 Include <limits.h>.
13123 (SIZE_MAX): Define if the headers do not.
13124 (verror): Do not give up if vsnprintf returns a negative count.
13125 Instead, grow the buffer. This ports to Windows vsnprintf, which
13126 does not conform to C99. Problem reported by Eli Zaretskii.
13127 Also, simplify the allocation scheme, by avoiding the need for
13128 calling realloc, and removing the ALLOCATED variable.
13130 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13132 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13133 But keep the doprint source code for now, as we might revamp it
13134 and use it again (Bug#8435).
13135 * lisp.h (doprnt): Remove.
13136 * Makefile.in (base_obj): Remove doprnt.o.
13137 * deps.mk (doprnt.o): Remove.
13139 error: Print 32- and 64-bit integers portably (Bug#8435).
13140 Without this change, on typical 64-bit hosts error ("...%d...", N)
13141 was used to print both 32- and 64-bit integers N, which relied on
13142 undefined behavior.
13143 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13144 * lisp.h (error, verror): Mark as printf-like functions.
13145 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13146 Report overflow in size calculations when allocating printf buffer.
13147 Do not truncate output string at its first null byte.
13148 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13149 Truncate the output at a character boundary, since vsnprintf does not
13151 * charset.c (check_iso_charset_parameter): Convert internal
13152 character to string before calling 'error', since %c now has the
13154 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13155 overflow when computing char to be passed to 'error'. Do not
13156 pass Lisp_Object to 'error'; pass the integer instead.
13157 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13158 formatted with plain %d.
13160 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13162 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13164 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13166 * xterm.c (x_catch_errors): Remove duplicate declaration.
13168 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13170 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13172 2011-04-10 Jim Meyering <meyering@redhat.com>
13174 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13175 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13176 return ssize_t not "int", and use size_t as the buffer length.
13177 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13178 * gnutls.h: Update declarations.
13179 * process.c (read_process_output): Use ssize_t, to match.
13180 (send_process): Likewise.
13182 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13184 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13186 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13188 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13189 Use unsigned char, to match FcChar8 type definition.
13191 * xterm.c (handle_one_xevent):
13192 * xmenu.c (create_and_show_popup_menu):
13193 * xselect.c (x_decline_selection_request)
13194 (x_reply_selection_request): Avoid type-punned deref of X events.
13196 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13198 Fix some uses of `int' instead of EMACS_INT.
13199 * search.c (string_match_1, fast_string_match)
13200 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13201 (scan_buffer, find_next_newline_no_quit)
13202 (find_before_next_newline, search_command, Freplace_match)
13203 (Fmatch_data): Make some `int' variables be EMACS_INT.
13205 * xdisp.c (display_count_lines): 3rd argument and return value now
13206 EMACS_INT. All callers changed.
13207 (pint2hrstr): Last argument is now EMACS_INT.
13209 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13210 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13211 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13212 (decode_coding_utf_16, decode_coding_emacs_mule)
13213 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13214 (decode_coding_ccl, decode_coding_charset)
13215 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13216 (decode_coding_iso_2022, decode_coding_emacs_mule)
13217 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13218 <char_offset, last_offset>: Declare EMACS_INT.
13219 (encode_coding_utf_8, encode_coding_utf_16)
13220 (encode_coding_emacs_mule, encode_invocation_designation)
13221 (encode_designation_at_bol, encode_coding_iso_2022)
13222 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13223 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13225 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13226 (encode_invocation_designation): Last argument P_NCHARS is now
13228 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13229 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13231 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13234 * ccl.c (Fccl_execute_on_string): Declare some variables
13237 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13239 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13241 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13243 * process.c (Fformat_network_address): Doc fix.
13245 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13247 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13249 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13251 * keyboard.c (read_char): Call Lisp function help-form-show,
13252 instead of using internal_with_output_to_temp_buffer.
13253 (Qhelp_form_show): New var.
13254 (syms_of_keyboard): Use DEFSYM macro.
13256 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13258 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13260 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13262 * process.c (Flist_processes): Remove to Lisp.
13263 (list_processes_1): Delete.
13265 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13267 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13269 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13271 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13273 Fix more problems found by GCC 4.6.0's static checks.
13275 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13277 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13279 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13281 * xdisp.c (vmessage): Mark as a printf-like function.
13283 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13285 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13287 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13288 printf-like functions.
13289 (tiff_load): Add casts to remove these marks before passing them
13290 to system-supplied API.
13292 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13294 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13295 This avoids several warnings with gcc -Wstrict-overflow.
13296 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13297 directly, rather than having caller test rule sign. This avoids
13298 some unnecessary tests.
13299 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13300 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13301 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13303 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13304 (xfont_open): Avoid unnecessary tests.
13306 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13308 * composite.h, composite.c (composition_gstring_put_cache):
13309 Use EMACS_INT, not int, for length.
13311 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13312 breaking out part of COMPOSITION_DECODE_RULE.
13313 (COMPOSITION_DECODE_RULE): Use it.
13314 * composite.c (get_composition_id): Remove unused local vars,
13315 by using the new macro.
13317 * textprop.c (set_text_properties_1): Change while to do-while,
13318 since the condition is always true at first.
13320 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13321 (interval_deletion_adjustment): Return unsigned value.
13324 * process.c (list_processes_1, create_pty, read_process_output):
13325 (exec_sentinel): Remove vars that were set but not used.
13326 (create_pty): Remove unnecessary "volatile"s.
13327 (Fnetwork_interface_info): Avoid possibility of int overflow.

13334 (update_syntax_table): Use unsigned instead of int.
13336 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13337 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13338 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13340 * print.c (print_error_message): Avoid int overflow.
13342 * font.c (font_list_entities): Redo for clarity,
13343 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13345 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13346 (font_score): Avoid potential overflow in diff calculation.
13348 * fns.c (substring_both): Remove var that is set but not used.
13349 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13351 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13353 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13354 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13355 can always succeed if overflow has undefined behavior.
13357 * search.c (boyer_moore, wordify): Remove vars set but not used.
13358 (wordify): Omit three unnecessary tests.
13360 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13361 All callers changed. This avoids the need for an unused var.
13363 * casefiddle.c (casify_region): Remove var that is set but not used.
13365 * dired.c (file_name_completion): Remove var that is set but not used.
13367 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13369 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13370 (Finsert_file_contents): Remove unnecessary code checking fd.
13372 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13373 Check for integer overflow on size calculations.
13375 * buffer.c (Fprevious_overlay_change): Remove var that is set
13378 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13379 Remove vars that are set but not used.
13380 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13381 (timer_check_2): Mark vars as initialized.
13383 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13385 * image.c (lookup_image): Remove var that is set but not used.
13386 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13388 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13389 that are set but not used.
13391 * xfns.c (make_invisible_cursor): Don't return garbage
13392 if XCreateBitmapFromData fails (Bug#8410).
13394 * xselect.c (x_get_local_selection, x_handle_property_notify):
13395 Remove vars that are set but not used.
13397 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13398 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13400 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13401 Remove var that is set but not used.
13402 (scroll_bar_windows_size): Now size_t, not int.
13403 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13404 Check for overflow.
13406 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13407 (map_tty_color) [!defined MSDOS]: Likewise.
13409 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13411 * coding.c: Remove vars that are set but not used.
13412 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13413 All callers changed.
13414 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13415 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13416 (decode_coding_charset): Remove vars that are set but not used.
13418 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13419 that is set but not used.
13421 * print.c (print_object): Remove var that is set but not used.
13423 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13424 The gnulib version avoids calling malloc in the usual case,
13425 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13426 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13427 * filelock.c (current_lock_owner): Likewise.
13428 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13429 * sysdep.c: Include allocator.h, careadlinkat.h.
13430 (emacs_no_realloc_allocator): New static constant.
13431 (emacs_readlink): New function.
13432 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13433 ../lib/careadlinkat.h.
13435 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13437 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13438 first non-nil return value).
13440 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13442 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13443 if not defined (Bug#8403).
13445 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13447 * xdisp.c (display_count_lines): Remove parameter `start',
13448 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13449 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13450 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13451 (fill_stretch_glyph_string): Remove parameters `row' and `area',
13452 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13453 and thereabouts. All callers changed.
13454 (get_per_char_metric): Remove parameter `f', unused since
13455 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13457 2011-04-02 Jim Meyering <meyering@redhat.com>
13459 do not dereference NULL upon failed strdup
13460 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13461 (ns_get_family): Likewise.
13463 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13465 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13467 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13469 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13472 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13474 Add lexical binding.
13476 * window.c (Ftemp_output_buffer_show): New fun.
13477 (Fsave_window_excursion):

13480 * lread.c (lisp_file_lexically_bound_p): New function.
13481 (Fload): Bind Qlexical_binding.
13482 (readevalloop): Remove `evalfun' arg.
13483 Bind Qinternal_interpreter_environment.

13485 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13487 (syms_of_lread): Declare `lexical-binding'.
13489 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13491 * keyboard.c (eval_dyn): New fun.
13492 (menu_item_eval_property): Use it.
13494 * image.c (parse_image_spec): Use Ffunctionp.
13496 * fns.c (concat, mapcar1): Accept byte-code-functions.
13498 * eval.c (Fsetq): Handle lexical vars.
13499 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13500 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13501 (FletX, Flet): Obey lexical binding.
13502 (Fcommandp): Handle closures.
13503 (Feval): New `lexical' arg.
13504 (eval_sub): New function extracted from Feval. Use it almost
13505 everywhere where Feval was used. Look up vars in lexical env.
13507 (Ffunctionp): Move from subr.el.
13508 (Ffuncall): Handle closures.
13509 (apply_lambda): Remove `eval_flags'.
13510 (funcall_lambda): Handle closures and new byte-code-functions.
13511 (Fspecial_variable_p): New function.
13512 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13513 but without exporting it to Lisp.
13515 * doc.c (Fdocumentation, store_function_docstring):
13516 * data.c (Finteractive_form): Handle closures.
13518 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13521 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13523 (exec_byte_code): New function extracted from Fbyte_code to handle new
13524 calling convention for byte-code-functions. Add new byte-codes.
13526 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13528 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13530 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13532 * xdisp.c (redisplay_internal): Fix prototype.
13534 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13536 * xdisp.c (SCROLL_LIMIT): New macro.
13537 (try_scrolling): Use it when setting scroll_limit.
13538 Limit scrolling to 100 screen lines.
13539 (redisplay_window): Even when falling back on "recentering",
13540 position point in the window according to scroll-conservatively,
13541 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13543 (try_scrolling): When point is above the window, allow searching
13544 as far as scroll_max, or one screenful, to compute vertical
13545 distance from PT to the scroll margin position. This prevents
13546 try_scrolling from unnecessarily failing when
13547 scroll-conservatively is set to a value slightly larger than the
13548 window height. Clean up the case of PT below the margin at bottom
13549 of window: scroll_max can no longer be INT_MAX. When aggressive
13550 scrolling is in use, don't let point enter the opposite scroll
13551 margin as result of the scroll.
13552 (syms_of_xdisp) <scroll-conservatively>: Document the
13553 threshold of 100 lines for never-recentering scrolling.
13555 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13557 * dispextern.h (move_it_by_lines):
13558 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13559 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13560 (message_log_check_duplicate): Remove parameters `prev_bol' and
13561 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13562 (redisplay_internal): Remove parameter `preserve_echo_area',
13563 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13565 * indent.c (Fvertical_motion):
13566 * window.c (window_scroll_pixel_based, Frecenter):
13567 Don't pass `need_y_p' to `move_it_by_lines'.
13569 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13571 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13572 steal a few bits to be more compact.
13573 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13574 Remove unneeded casts.
13576 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13578 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13580 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13581 binding" message (bug#7967).
13583 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13585 Fix more problems found by GCC 4.6.0's static checks.
13587 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13588 Remove unused local var.
13590 * editfns.c (Fmessage_box): Remove unused local var.
13592 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13593 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13594 Omit unused local vars.
13595 * window.c (shrink_windows): Omit unused local var.
13596 * menu.c (digest_single_submenu): Omit unused local var.
13597 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13598 Omit unused local var.
13600 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13601 Don't assume string length fits in int.
13602 (keyremap_step, read_key_sequence): Use size_t for sizes.
13603 (read_key_sequence): Don't check last_real_key_start redundantly.
13605 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13606 instead of alloca (Bug#8344).
13608 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13609 (Fbacktrace_frame): Don't assume nframes fits in int.
13611 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13613 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13616 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13618 * cm.c (calccost): Turn while-do into do-while, for clarity.
13620 * keyboard.c (syms_of_keyboard): Use the same style as later
13621 in this function when indexing through an array. This also
13622 works around GCC bug 48267.
13624 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13626 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

13629 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13631 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13632 This avoids undefined behavior on integer overflow, and is a bit
13633 more convenient anyway since it is compared to a size_t variable.
13635 Variadic C functions now count arguments with size_t, not int.
13636 This avoids an unnecessary limitation on 64-bit machines, which
13637 caused (substring ...) to crash on large vectors (Bug#8344).
13638 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13639 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13645 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13646 (funcall_lambda, mark_backtrace): Likewise.
13647 * fns.c (concat): Likewise.
13648 * frame.c (x_set_frame_parameters): Likewise.
13649 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13650 0 if not found, not -1. All callers changed.
13652 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13653 (stack_copy_size): Now size_t, not int.
13654 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13656 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13658 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13659 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13662 * lisp.h (multibyte_char_to_unibyte):
13663 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13664 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13665 * character.h (CHAR_TO_BYTE8):
13666 * cmds.c (internal_self_insert):
13667 * editfns.c (general_insert_function):
13668 * keymap.c (push_key_description):
13669 * search.c (Freplace_match):
13670 * xdisp.c (message_dolog, set_message_1): All callers changed.
13672 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13674 * keyboard.c (safe_run_hook_funcall): New function.
13675 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13676 don't set the hook to nil, but remove the offending function instead.
13677 (Qcommand_hook_internal): Remove, unused.
13678 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13679 Vcommand_hook_internal.
13681 * eval.c (enum run_hooks_condition): Remove.
13682 (funcall_nil, funcall_not): New functions.
13683 (run_hook_with_args): Call each function through a `funcall' argument.
13684 Remove `cond' argument, now redundant.
13685 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13686 (Frun_hook_with_args_until_failure): Adjust accordingly.
13687 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13689 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13691 * dispextern.h (string_buffer_position): Remove declaration.
13693 * print.c (strout): Remove parameter `multibyte', unused since
13694 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13696 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13697 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13698 All callers changed.
13700 * w32.c (_wsa_errlist): Use braces for struct initializers.
13702 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13703 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13704 All callers changed.

13710 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13711 All callers changed.
13713 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13715 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13726 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
13728 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

13744 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13746 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13748 * w32.c (read_unc_volume): Use parameter `henum', instead of
13749 global variable `wget_enum_handle'.
13751 * keymap.c (describe_vector): Remove parameters `indices' and
13752 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

13767 * gtkutil.c (xg_maybe_add_timer):
13768 * keyboard.c (readable_events):
13769 * process.c (wait_reading_process_output):
13770 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
13772 * insdel.c (adjust_markers_gap_motion):
13773 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

13849 * term.c (Fsuspend_tty, Fresume_tty):
13850 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13851 * window.c (temp_output_buffer_show):

13857 * cmds.c (internal_self_insert):
13858 * callint.c (Fcall_interactively):
13859 * buffer.c (Fkill_all_local_variables):
13860 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13862 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13863 unconditionally since it does the check itself.
13865 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13867 Fix more problems found by GCC 4.5.2's static checks.
13869 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13870 the first time through the loop, since we know p0 < p1 then.
13871 This also avoids a gcc -Wstrict-overflow warning.
13873 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13874 leading to a memory leak, possible in functions like
13875 load_charset_map_from_file that can allocate an unbounded number
13876 of objects (Bug#8318).
13878 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13879 that could (at least in theory) be that large.
13881 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13882 This is less likely to overflow, and avoids undefined behavior if
13883 overflow does occur. All callers changed. Use strtoul to scan
13884 for the unsigned long integer.
13885 (pint2hrstr): Simplify and tune code slightly.
13886 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13901 * process.c (Fmake_network_process): Use socklen_t, not int,
13902 where POSIX says socklen_t is required in portable programs.
13903 This fixes a porting bug on hosts like 64-bit HP-UX, where
13904 socklen_t is wider than int (Bug#8277).
13905 (Fmake_network_process, server_accept_connection):
13906 (wait_reading_process_output, read_process_output):
13909 * process.c: Rename or move locals to avoid shadowing.

13916 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13917 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13919 Make tparam.h and terminfo.c consistent.
13920 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13921 Include tparam.h instead, since it declares them.
13922 * cm.h (PC): Remove extern decl; tparam.h now does this.
13923 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13924 * terminfo.c: Include tparam.h, to check interfaces.
13925 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13926 (tparam): Adjust signature to match interface in tparam.h;
13927 this removes some undefined behavior. Check that outstring and len
13928 are zero, which they always are with Emacs.
13929 * tparam.h (PC, BC, UP): New extern decls.
13931 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13932 (xftfont_open): Rename locals to avoid shadowing.
13934 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13935 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13936 (OTF_TAG_SYM): Omit macro if not needed.
13937 (ftfont_list): Remove unused local.
13938 (get_adstyle_property, ftfont_pattern_entity):
13939 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13940 Rename locals to avoid shadowing.
13942 * xfont.c (xfont_list_family): Mark var as initialized.
13944 * xml.c (make_dom): Now static.
13946 * composite.c (composition_compute_stop_pos): Rename local to
13948 (composition_reseat_it): Remove unused locals.
13949 (find_automatic_composition, composition_adjust_point): Likewise.
13950 (composition_update_it): Mark var as initialized.
13951 (find_automatic_composition): Mark vars as initialized,
13952 with a FIXME (Bug#8290).
13954 character.h: Rename locals to avoid shadowing.
13955 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13956 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13957 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13958 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13959 to avoid shadowing.
13961 * textprop.c (property_change_between_p): Remove; unused.
13963 * intervals.c (interval_start_pos): Now static.
13965 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13967 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13968 Rename locals to avoid shadowing.
13970 * sound.c (wav_play, au_play, Fplay_sound_internal):
13971 Fix pointer signedness.
13972 (alsa_choose_format): Remove unused local var.
13973 (wav_play): Initialize a variable to 0, to prevent undefined
13974 behavior (Bug#8278).
13976 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13978 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13980 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13981 clobbering (Bug#8298).
13982 * sysdep.c (sys_subshell): Likewise.
13983 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13985 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13986 This should get cleaned up, so that child_setup has the
13987 same signature on all platforms.
13989 * callproc.c (call_process_cleanup): Now static.
13990 (relocate_fd): Rename locals to avoid shadowing.
13992 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

14120 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14121 some of which prompt warnings from gcc -Wbad-function-cast.
14122 (Fformat_time_string, Fencode_time, Finsert_char):

14151 (Fmemory_limit): Cast sbrk's returned value to char *.
14153 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14156 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14158 Use functions, not macros, for up- and down-casing (Bug#8254).
14159 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14160 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14161 to use the following functions instead of these macros.
14162 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14163 EMACS_INT, since callers assume the returned value fits in int.
14164 (upcase1): Likewise, for UPCASE_TABLE.
14165 (uppercasep, lowercasep, upcase): New static inline functions.
14166 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14176 (regex_compile, re_match_2_internal): Mark locals as initialized.
14177 (RETALLOC_IF): Define only if needed.
14178 (WORDCHAR_P): Likewise. This one is never needed, but is used
14179 only in a comment talking about a compiler bug, so put inside
14180 the #if 0 of that comment.
14181 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14182 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14208 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14209 New macros, so that the caller can use some names other than
14210 gcpro1, gcpro2, etc.
14211 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14213 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14214 argument, for consistency with GCPRO2_VAR, etc: it is now the
14215 prefix of the variable, not the variable itself. All uses
14217 * dired.c (directory_files_internal, file_name_completion):
14218 Rename locals to avoid shadowing.
14220 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14221 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14222 dired.c's scmp function, had undefined behavior.
14223 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14224 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14225 * buffer.h: ... to here, because these macros use current_buffer,
14226 and the new implementation with inline functions needs to have
14227 current_buffer in scope now, rather than later when the macros
14229 (downcase, upcase1): New static inline functions.
14230 (DOWNCASE, UPCASE1): Reimplement using these functions.
14231 This avoids undefined behavior in expressions like
14232 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14233 from race conditions in accessing the global variables
14234 case_temp1 and case_temp2.
14235 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14236 * lisp.h (case_temp1, case_temp2): Remove their decls.
14237 * character.h (ASCII_CHAR_P): Move from here ...
14238 * lisp.h: ... to here, so that the inline functions mentioned
14239 above can use them.
14241 * dired.c (directory_files_internal_unwind): Now static.
14243 * fileio.c (file_name_as_directory, directory_file_name):

14246 (file_name_as_directory): Use const pointers when appropriate.
14247 (Fexpand_file_name): Likewise. In particular, newdir might
14248 point at constant storage, so make it a const pointer.
14249 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14250 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14252 (Fset_file_times, Finsert_file_contents, auto_save_error):

14257 to avoid shadowing.
14259 * marker.c (bytepos_to_charpos): Remove; unused.
14261 * lisp.h (verify_bytepos, count_markers): New decls,
14262 so that gcc does not warn that these functions aren't declared.
14264 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14265 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14266 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14267 (copy_text): Remove unused local var.
14269 * filelock.c (within_one_second): Now static.
14270 (lock_file_1): Rename local to avoid shadowing.
14272 * buffer.c (fix_overlays_before): Mark locals as initialized.
14273 (fix_start_end_in_overlays): Likewise. This function should be
14274 simplified by using pointers-to-pointers, but that's a different
14276 (switch_to_buffer_1): Now static.
14277 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14278 (report_overlay_modification): Rename locals to avoid shadowing.
14280 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14281 Fix pointer signedness issue.
14282 (sys_subshell): Mark local as volatile if checking for lint,
14283 to suppress a gcc -Wclobbered warning that does not seem to be right.
14284 (MAXPATHLEN): Define only if needed.
14286 * process.c (serial_open, serial_configure): Move decls from here ...
14287 * systty.h: ... to here, so that they can be checked.
14289 * fns.c (get_random, seed_random): Move extern decls from here ...
14290 * lisp.h: ... to here, so that they can be checked.
14292 * sysdep.c (reset_io): Now static.
14293 (wait_for_termination_signal): Remove; unused.
14295 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14296 (copy_keymap_item, append_key, push_text_char_description):
14298 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14299 (DENSE_TABLE_SIZE): Remove; unused.
14300 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14301 (describe_map_tree):
14302 Rename locals to avoid shadowing.
14304 * keyboard.c: Declare functions static if they are not used elsewhere.

14326 if GCC considers string literals to be constants.
14328 * lisp.h (fatal_error_signal): Add decl, since it's exported.
