490 * xfns.c (syms_of_xfns): Likewise.
492 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
494 Fast save_excursion_save and save_excursion_restore.
495 * lisp.h (struct Lisp_Excursion): New data type.
496 (PVEC_EXCURSION): New pseudovector type.

513 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
514 emacs.c, as this is a more-suitable home. Had this been done earlier
515 the fix for 12036 would have avoided some of the problems noted in
516 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
517 would have been more obvious.
518 * emacs.c: Do not include <verify.h>; no longer needed.
519 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
520 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
521 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
522 Remove; now done in lisp.h.

525 (DATA_SEG_BITS): Use it.
526 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
527 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
528 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
529 not be usable in #if. This simplifies things.
531 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
533 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
535 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

538 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
539 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
540 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
541 Adjust to changes in lisp.h and emacs.c, by using
542 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
543 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
544 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
545 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
546 instead of gdb_valbits.
547 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
548 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
549 instead of gdb_array_mark_flag.
550 (xboolvector): Get size from $->size, not $->header.size.
551 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
552 (xreload, hook-run, hookpost-run): Remove.
553 * emacs.c: Include <verify.h>.
554 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
555 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
557 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
558 (gdb_USE_LSB_TAG): New enum constants.
559 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
560 Also define these as enum constants, so they're visible to GDB.
561 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
562 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
563 as constants, so they're visible to GDB.
564 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
565 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
566 Now enum constants, not macros, so they're visible to GDB.
567 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
568 more convenient now. All uses changed.
569 (VALMASK) [USE_LSB_TAG]: Also define in this case.
570 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
572 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

577 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
579 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
580 add argument, tune behavior, and adjust all callers.
582 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
584 Use typedef for EMACS_INT, EMACS_UINT.
585 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
586 than macros. This simplifies debugging in the usual case, since
587 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
588 and it allows expressions involving EMACS_INT casts.
589 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
591 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

603 Adjust buffer text indirection counters at the end of Fkill_buffer.
604 * buffer.c (Fkill_buffer): Adjust indirection counters when the
605 buffer is definitely dead. This should really fix an issue reported
606 by Christoph Scholtes again. (Bug#12007).
607 (init_buffer_once): Initialize indirection counters of
608 buffer_defaults and buffer_local_symbols (for sanity and safety).
610 2012-07-24 Eli Zaretskii <eliz@gnu.org>
612 * xdisp.c (init_iterator): Don't compute dimensions of truncation
613 and continuation glyphs on tooltip frames, leave them at zero.
614 Avoids continued lines in tooltips. (Bug#11832)
616 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
618 Simplify copy_overlay.
619 * buffer.c (copy_overlay): Simplify. Use build_marker.

625 or invalid. (Bug#12025)
627 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as

643 Swap buffer text indirection counters in Fbuffer_swap_text.
644 * buffer.c (Fbuffer_swap_text): Swap indirections too.
645 This avoids crash reported by Christoph Scholtes at
646 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
648 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
650 * nsmenu.m (Popdown_data): New struct.

673 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
675 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
676 as it's limited by the amount of memory, not by INT_MAX.
678 2012-07-21 Eli Zaretskii <eliz@gnu.org>
680 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
681 in special-event-map. See the discussion at

761 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
762 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
763 'for_each_per_buffer_object_at'.
764 All uses changed. It's better to use upper-case for macros that
765 cannot be implemented as functions, to give the reader a clue

1399 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
1401 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
1403 Remove "#define unix" that is no longer needed (Bug#11905).
1404 * s/aix4-2.h (unix): Remove; no longer needed.
1406 EMACS_TIME simplification (Bug#11875).
1407 This replaces macros (which typically do not work in GDB)
1408 with functions, typedefs and enums, making the code easier to debug.
1409 The functional style also makes code easier to read and maintain.
1410 * systime.h: Include <sys/time.h> on all hosts, not just if
1411 WINDOWSNT, since 'struct timeval' is needed in general.
1412 (EMACS_TIME): Now a typedef, not a macro.
1413 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1415 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
1416 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
1417 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
1418 (EMACS_TIME_LE): Now functions, not macros.
1419 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1420 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1421 which are not functions. All uses rewritten to use:
1422 (make_emacs_time): New function.
1423 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1424 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1425 not functions. All uses rewritten to use the following, respectively:
1426 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1427 (add_emacs_time, sub_emacs_time): New functions.
1428 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1429 * fileio.c (Fcopy_file):
1430 * xterm.c (XTflash): Get the current time closer to when it's used.
1431 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1435 Simplify by avoiding confusing use of strncpy etc.
1436 * doc.c (Fsnarf_documentation):
1437 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
1438 * frame.c (Fmake_terminal_frame):
1439 * gtkutil.c (get_utf8_string):
1441 * nsmenu.m (ns_update_menubar):
1442 * regex.c (regerror):
1443 Prefer memcpy to strncpy and strncat when either will do.
1444 * fileio.c (Fsubstitute_in_file_name):
1445 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1446 (menu_separator_name_p):
1447 * nsmenu.m (ns_update_menubar):
1448 Prefer memcmp to strncmp when either will do.
1449 * nsterm.m: Include <ftoastr.h>.
1451 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1452 Prefer snprintf to strncpy.
1453 * nsterm.m (ns_term_init):
1454 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1455 * nsterm.m (ns_term_init):
1456 Avoid the need for strncpy, by using build_string or
1457 make_unibyte_string directly. Use dtoastr, not snprintf.
1458 * process.c (Fmake_network_process): Diagnose service names that
1459 are too long, rather than silently truncating them or creating
1460 non-null-terminated names.
1461 (Fnetwork_interface_info): Likewise, for interface names.
1462 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1463 Prefer sprintf to strncat.
1464 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1465 Prefer vsnprintf to vsprintf + strncpy.
1467 2012-07-10 Glenn Morris <rgm@gnu.org>
1469 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1470 Clarify fallback case.
1472 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1474 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1475 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1476 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1477 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1478 where argument type is known to be a Lisp_Cons.
1480 2012-07-10 Tom Tromey <tromey@redhat.com>
1482 * bytecode.c (BYTE_CODE_THREADED): New macro.
1483 (BYTE_CODES): New macro. Replaces all old byte-code defines.
1484 (enum byte_code_op): New type.
1485 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
1486 (exec_byte_code): Use them. Use token threading when applicable.
1488 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1490 Optimize pure C strings initialization.
1491 * lisp.h (make_pure_string): Fix prototype.
1492 (build_pure_c_string): New function, defined as static inline. This
1493 provides a better opportunity to optimize away calls to strlen when
1494 the function is called with compile-time constant argument.
1495 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1496 argument, adjust users accordingly. Use build_pure_c_string where
1498 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1499 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1500 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1502 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1504 Avoid calls to strlen in miscellaneous functions.
1505 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1506 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1507 * lread.c (openp): Likewise.
1509 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1511 Avoid calls to strlen in path processing functions.
1512 * fileio.c (file_name_as_directory): Add comment. Change to add
1513 srclen argument and return the length of result. Adjust users
1515 (directory_file_name): Fix comment. Change to add srclen argument,
1516 swap 1st and 2nd arguments to obey the common convention. Adjust
1518 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1520 2012-07-10 Glenn Morris <rgm@gnu.org>
1522 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1523 Move PENDING_OUTPUT_COUNT definition to configure.
1525 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1526 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1527 * s/gnu.h (DATA_START): Move definitions to configure.
1529 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1530 We include usg5-4-common.h, which defines them both.
1532 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1533 O_RDONLY already includes it).
1535 Stop ns builds setting the EMACSLOADPATH environment variable.
1536 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1537 Now it does not set EMACSLOADPATH, just returns the load-path string.
1538 * nsterm.h: Update accordingly.
1539 * lread.c [HAVE_NS]: Include nsterm.h.
1540 (init_lread) [HAVE_NS]: Use ns_load_path.
1541 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1543 2012-07-09 Glenn Morris <rgm@gnu.org>
1545 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1546 since the included bsd-common.h does so.
1548 Stop ns builds setting the EMACSPATH environment variable.
1549 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1550 (ns_init_paths): Do not set EMACSPATH.
1551 * nsterm.h (ns_exec_path): Add it.
1552 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1555 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1557 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1559 * process.c (wait_reading_process_output): 'waitchannels' was unset
1560 when read_kbd || !NILP (wait_for_cell); fix this.
1562 Add GCC-style 'const' attribute to functions that can use it.
1563 * character.h (char_resolve_modifier_mask):
1564 * keyboard.h (make_ctrl_char):
1565 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1566 (init_character_once, next_almost_prime, init_fns, init_image)
1567 (flush_pending_output, init_sound):
1568 * mem-limits.h (start_of_data):
1569 * menu.h (finish_menu_items):
1570 Add ATTRIBUTE_CONST.

1572 Declare the dummy function with ATTRIBUTE_CONST.
1573 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1574 Add decls with ATTRIBUTE_CONST.
1576 Minor improvements to make_formatted_string.
1577 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1578 where int is good enough, as vsprintf returns an int.
1579 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1581 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1583 Use make_formatted_string to avoid double length calculation.
1584 * lisp.h (make_formatted_string): New prototype.
1585 * alloc.c (make_formatted_string): New function.
1586 * buffer.c (Fgenerate_new_buffer_name): Use it.
1587 * dbus.c (syms_of_dbusbind): Likewise.
1588 * editfns.c (Fcurrent_time_zone): Likewise.
1589 * filelock.c (get_boot_time): Likewise.
1590 * frame.c (make_terminal_frame, set_term_frame_name)
1591 (x_report_frame_params): Likewise.
1592 * image.c (gs_load): Likewise.
1593 * minibuf.c (get_minibuffer): Likewise.
1594 * msdos.c (dos_set_window_size): Likewise.
1595 * process.c (make_process): Likewise.
1596 * xdisp.c (ensure_echo_area_buffers): Likewise.

1599 2012-07-09 Glenn Morris <rgm@gnu.org>
1601 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
1602 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
1603 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1604 * nsterm.h (ns_etc_directory): Add it.
1605 * callproc.c [HAVE_NS]: Include nsterm.h.
1606 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1608 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1610 Move marker debugging code under MARKER_DEBUG.
1611 * marker.c (MARKER_DEBUG): Move marker debugging code under
1612 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1613 for bootstrap with --enable-checking (~3x slowdown reported
1614 by Juanma Barranquero <lekktu@gmail.com>).
1615 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1617 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1619 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1620 See <http://bugs.gnu.org/11825#29>.
1622 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1624 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1625 has no font, use the frame's font. (Bug#11813)
1626 (display_line): Add commentary about displaying truncation glyphs
1628 (produce_special_glyphs): Move here from term.c.
1630 * term.c (produce_special_glyphs): Move to xdisp.c.
1632 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1635 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1637 * xdisp.c (display_line): Avoid warning about implicit declaration
1640 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1642 * lisp.h: Remove empty conditional.
1644 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1646 * lread.c (load_path_check): Now static.
1648 Fix some minor --with-ns problems found by static checking.
1649 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1650 (x_set_font) [!HAVE_X_WINDOWS]:
1651 * image.c (xpm_load_image) [HAVE_NS]:
1652 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1653 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1654 Remove unused local.
1655 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1656 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1657 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1658 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1659 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1660 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1661 Fix pointer signedness problem.
1662 * xfaces.c (FRAME_X_FONT_TABLE):
1663 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1665 2012-07-07 Glenn Morris <rgm@gnu.org>
1667 * lread.c (load_path_check): New function, split from init_lread.
1668 (init_lread): Reorganize. Motivation:
1669 If EMACSLOADPATH is set, check/warn about that rather than the
1670 defaults, which we are not going to use. Hence we can remove
1671 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1672 Don't warn if site-lisp directories are missing.
1673 If not installed, start from a blank load-path, since
1674 PATH_LOADSEARCH refers to the eventual installation directories.
1676 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1678 Support truncation and continuation glyphs on GUI frames, when
1679 fringes are disabled. (Bug#11832)
1680 * xdisp.c (init_iterator): Get dimensions of truncation and
1681 continuation glyphs even if on GUI frames. Adjust
1682 it->last_visible_x on GUI frames when the left or right fringes,
1683 or both, are absent.
1684 (start_display, move_it_in_display_line_to): Handle the case of a
1685 GUI frame without a fringe to display continuation or truncation
1687 (insert_left_trunc_glyphs): Support GUI frames: make sure
1688 truncation glyphs overwrite enough glyphs from the current line to
1689 have sufficient space in pixels.
1690 (display_line): Support truncation and continuation glyphs on GUI
1691 frames. If some spare pixels are left on the line after inserting
1692 the truncation glyphs, fill that space with a stretch glyph of a
1693 suitably computed width.
1695 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1696 produce_glyphs, to support GUI sessions.
1698 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1700 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1702 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1704 Do not require float-time's arg to fit in time_t (Bug#11825).
1705 This works better on hosts where time_t is unsigned, and where
1706 float-time is applied to the (negative) difference between two times.
1707 * editfns.c (decode_time_components): Last arg is now double *,
1708 not int *, and means to store all the result as a double, without
1709 worrying about whether the seconds part fits in time_t.
1710 All callers changed.
1711 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1712 All callers changed.
1713 (Ffloat_time): Do not fail merely because the specified time falls
1714 outside of time_t range.
1716 2012-07-07 Glenn Morris <rgm@gnu.org>
1718 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1719 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1720 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1722 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1724 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1725 Update dependencies.
1727 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1729 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1731 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1732 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1733 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1734 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1735 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1736 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1738 * xfont.c (compare_font_names): Redo to omit the need for casts.
1740 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1742 * xfns.c (Fx_change_window_property): Doc fix.
1743 * w32fns.c (Fx_change_window_property): Doc fix.
1745 * w32fns.c (Fx_window_property): Accept the same arguments as the
1746 X Windows version. Doc fix.
1747 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1749 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1750 Eli Zaretskii <eliz@gnu.org>
1752 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1753 Windows-specific code from nt/config.nt moved here.
1754 Obsolete settings removed.
1756 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1758 * process.c: Avoid unnecessary calls to gettime.
1759 (wait_reading_process_output): Don't get the time of day
1760 when gobbling data immediately and not waiting, as there's no need
1761 for it in that case. This removes a FIXME.
1763 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1765 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1766 is defined (Bug#11768).
1768 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1770 Fix marker debugging code.
1771 * marker.c (byte_char_debug_check): Do not perform the check
1772 if buffer is not multibyte.
1773 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1774 Call byte_char_debug_check with correct arguments.
1776 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1778 Compile marker debugging code only if ENABLE_CHECKING is defined.
1779 * marker.c (byte_char_debug_check, count_markers):
1780 Use only if ENABLE_CHECKING is defined.
1781 (byte_debug_flag): Remove.
1782 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1783 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1785 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1787 Avoid code repetition in marker-related functions.
1788 * marker.c (attach_marker): New function.
1789 (Fset_marker, set_marker_restricted, set_marker_both)
1790 (set_marker_restricted_both): Use it.
1791 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1792 Consistently rename charno to charpos.
1793 (marker_position): Add eassert.
1794 (marker_byte_position): Convert to eassert.
1796 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1798 Simplify list operations in unchain_overlay and unchain_marker.
1799 * buffer.c (unchain_overlay): Simplify. Add comment.
1800 * marker.c (unchain_marker): Simplify. Fix comments.
1802 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1804 Introduce fast path for the widely used marker operation.
1805 * alloc.c (build_marker): New function.
1806 * lisp.h (build_marker): New prototype.
1807 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1808 * composite.c (autocmp_chars): Likewise.

1810 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1811 (save_restriction_save): Use build_marker.
1812 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1813 * window.c (save_window_save): Likewise.
1815 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1817 Do not use Fdelete_overlay in delete_all_overlays
1818 to avoid redundant calls to unchain_overlay.
1819 * buffer.c (drop_overlay): New function.
1820 (delete_all_overlays, Fdelete_overlay): Use it.
1821 * minibuf.c (get_minibuffer): Fix comment.
1823 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1825 Port to OpenBSD 5.1 amd64.
1826 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1827 This is needed for OpenBSD, and should be harmless on all BSD systems.
1828 Also, include <sys/sysctl.h>, as it should be available on all
1829 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1830 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1831 use p_pid member, not kp_proc.pid.
1833 2012-07-06 Glenn Morris <rgm@gnu.org>
1835 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1837 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1839 More xmalloc and related cleanup.

1848 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1850 Omit needless casts involving void * pointers and allocation.
1851 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1852 as the former is more robust if P's type is changed.
1853 Prefer xzalloc to xmalloc + memset 0.
1854 Simplify malloc-or-realloc to realloc.
1855 Don't worry about xmalloc returning a null pointer.
1856 Prefer xstrdup to xmalloc + strcpy.
1857 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1859 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1860 alloca of a constant.
1862 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1864 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1865 hscroll is larger than the line width. Fixes long and futile
1866 looping inside extend_face_to_end_of_line (on a TTY) producing
1867 glyphs that are not needed and thrown away.
1869 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

1881 not defined (Bug#11768).
1882 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1883 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1884 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1885 followed by gtk_box_set_homogeneous (Bug#11768).
1886 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1887 (update_theme_scrollbar_width, xg_create_scroll_bar):
1888 Use gtk_scrollbar_new (Bug#11768).
1889 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

1897 * xdisp.c (window_hscroll_limited): New function.
1898 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1899 coordinates when window's hscroll is set to insanely large

1971 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1972 This should be fixed in a better way; see Eli Zaretskii in
1973 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1974 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1976 * fileio.c (time_error_value): Rename from special_mtime.
1977 The old name's problems were noted by Eli Zaretskii in
1978 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1980 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1981 This variable's comment says Emacs needs at least one GDB-visible
1982 symbol of type enum pvec_type, to work around GDB problems.
1983 The symbol's value doesn't matter.
1985 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1986 that causes compilation to fail on pre-C99 compilers.
1988 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1990 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1996 headers for buffer_defaults and buffer_local_symbols.
1997 Reported by Juanma Barranquero <lekktu@gmail.com>.
1999 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2001 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2002 * lisp.h (enum pvec_type): Use fewer bits.
2003 (PSEUDOVECTOR_SIZE_BITS): New constant.
2004 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2005 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2006 change in pvec_type.
2007 (PSEUDOVECTOR_TYPEP): New macro.

2013 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2014 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2015 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2016 abusing vector->header.next.nbytes.
2017 (live_vector_p): Use PVEC_TYPE.
2018 (mark_object): Adapt code to extract pvectype. Use switch.
2020 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2022 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2023 Tighten new eassert a bit.
2025 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2027 Fix compilation with --enable-gcc-warnings and -O1
2029 * doprnt.c (doprnt): Change type of tem to int, initialize
2030 to avoid compiler warning. Add eassert.
2031 * search.c (simple_search): Initialize match_byte to avoid
2032 compiler warning. Add eassert.
2034 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2036 Avoid weird behavior with large horizontal scrolls.
2037 Without this change, for example, large hscroll values would
2038 mess up Emacs's display on Fedora 15 x86, presumably due to
2039 overflows in int calculations in the display code.
2040 Also, if buffers had long lines, Emacs would freeze.
2041 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2042 (set_window_hscroll): New function, containing the old guts of
2043 Fset_window_hscroll. Return the clipped value.
2044 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2045 This avoids the need to check against PTRDIFF_MAX.
2047 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2049 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2051 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2053 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2055 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2056 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2057 since GCC 4.4.6 issues a bogus warning for them.
2059 Fix bugs in file timestamp newness comparisons.
2060 * fileio.c (Ffile_newer_than_file_p):
2061 * lread.c (Fload): Use full timestamp resolution of files,
2062 not just the 1-second resolution, so that files that are only
2063 slightly newer still count as newer.
2064 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2065 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2067 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2069 * fileio.c: Improve handling of file time marker. (Bug#11852)
2070 (special_mtime): New function.
2071 (Finsert_file_contents, Fverify_visited_file_modtime):
2072 Use it to set special mtime values consistently.
2074 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2076 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2077 marker for non-existing file. (Bug#11852)
2079 2012-07-03 Glenn Morris <rgm@gnu.org>
2081 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2082 and did not make it into globals.h).
2084 2012-07-03 Tom Tromey <tromey@redhat.com>
2086 * window.c (Fset_window_margins, Fset_window_fringes)
2087 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2088 * textprop.c (Fprevious_property_change): No longer static.
2089 * syntax.c (Fsyntax_table_p): No longer static.
2090 * process.c (Fget_process, Fprocess_datagram_address): No longer

2111 * intervals.h: Remove EXFUNs.
2112 * fontset.h: Remove EXFUN.

2117 * w32term.h: Remove EXFUNs.
2118 * window.h: Remove EXFUNs.
2119 * xsettings.h: Remove EXFUN.
2120 * xterm.h: Remove EXFUN.
2122 2012-07-03 Glenn Morris <rgm@gnu.org>
2124 * lisp.h (Frandom): Make it visible to C.
2125 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2126 buffer for invisible buffers. (Bug#1229)
2128 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2130 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2131 values which aren't power of 2.
2132 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2133 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2136 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2138 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2140 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2142 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2144 * alloc.c (allocate_vector_block): Remove redundant
2145 calls to mallopt if DOUG_LEA_MALLOC is defined.
2146 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2147 avoid calls to mallopt if zero_vector is returned.
2149 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2151 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2152 is enabled, avoid dereferencing NULL current_sblock if
2155 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2157 Cleanup basic buffer management.
2158 * buffer.h (struct buffer): Change layout to use generic vector
2159 marking code. Fix some comments. Change type of 'clip_changed'
2160 to bitfield. Remove unused #ifndef old.
2161 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2162 (GET_OVERLAYS_AT): Fix indentation.
2163 (for_each_per_buffer_object_at): New macro.
2164 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2166 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2167 * alloc.c (allocate_buffer): Adjust to match new layout of
2168 struct buffer. Fix comment.
2169 (mark_overlay): New function.

2171 Lisp area of struct buffer.
2172 (mark_object): Use it. Adjust marking of misc objects
2173 and related comments.
2175 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2177 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2178 wrapper that is not needed because the wrapped code is a no-op (zero
2179 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2180 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2182 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2184 * alloc.c (mark_buffer): Simplify. Remove prototype.
2185 (mark_object): Add comment. Reorganize marking of vector-like
2186 objects. Use CHECK_LIVE for all vector-like objects except buffers
2187 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2188 redundant calls to mark_vectorlike for bool vectors.
2190 2012-06-30 Glenn Morris <rgm@gnu.org>
2192 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2194 * epaths.in (PATH_SITELOADSEARCH): New.
2195 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2196 This is rather than relying on --enable-locallisppath elements
2197 having "site-lisp" in their names. (Bug#10208#25, 11658)
2199 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2201 * w32proc.c (sys_select): Accept and ignore one more argument.
2203 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2205 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2206 (pselect) [!MS_DOS]: Redirect to sys_select.
2208 * sysdep.c: Don't include dos.h and dosfns.h.
2210 * process.c (sys_select):
2211 * msdos.c (sys_select): Accept one more argument and ignore it.
2213 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2214 adapt data types and code to that.
2217 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2218 which clashes with the gnulib function of the same name.
2220 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2222 * font.c (font_style_to_value, font_style_symbolic)
2223 (font_prop_validate_style): Add type checks for values in
2226 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2228 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2231 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2233 * xdisp.c (try_window_id): Undo last change.
2235 * w32.c (getwd): Adjust commentary about startup_dir.
2236 (init_environment): Always call sys_access, even in non-MSVC
2237 builds. Don't chdir to the directory of the Emacs executable.
2238 This undoes code from 1997 which was justified by the need to
2239 "avoid conflicts when removing and renaming directories". But its
2240 downside was that every relative file name was being interpreted
2241 relative to the directory of the Emacs executable, which can never
2242 be TRT. In particular, it broke sys_access when called with
2243 relative file names.
2244 (sys_access): Map GetLastError to errno.
2246 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2248 * window.h (struct window): Change type of 'fringes_outside_margins'

2252 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2255 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2257 * gnutls.c (emacs_gnutls_handshake):
2258 Add QUIT to make the loop interruptible.
2260 2012-06-29 Glenn Morris <rgm@gnu.org>
2262 * charset.c (init_charset): Make lack of etc/charsets fatal.
2264 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2266 * editfns.c (region_limit): Fix type mismatch.
2268 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2270 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2271 undefined. Convert from xassert to eassert.
2272 * nsmenu.m: Convert from xassert to eassert.
2273 * nsterm.m: Likewise.
2275 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2277 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2279 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2281 Avoid integer overflow on scroll-left and scroll-right.
2282 * window.c (HSCROLL_MAX): New macro.
2283 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2284 overflow when requested scroll falls outside ptrdiff_t range.
2286 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2288 * window.h (struct window): Change type of 'hscroll',
2289 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2290 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2291 Adjust users accordingly.
2292 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2293 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2294 from EMACS_INT to ptrdiff_t.
2295 (make_window): Omit redundant initialization.
2297 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2299 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2301 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2303 * window.h (struct window): Change type of 'use_time' and
2304 'sequence_number' from Lisp_Object to int.
2305 * frame.c (make_frame): Adjust users accordingly.
2306 * print.c (print_object): Likewise.
2307 * window.c (select_window, Fwindow_use_time, make_parent_window)
2308 (make_window): Likewise.
2310 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2312 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2313 enabled with --enable-checking=[all,glyphs] configure option.
2314 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2315 adjust comments accordingly.
2316 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be

2438 Use sprintf return value instead of invoking strlen on result.
2439 In the old days this wasn't portable, since some sprintf
2440 implementations returned char *. But they died out years ago and
2441 Emacs already assumes sprintf returns int.
2442 Similarly for float_to_string.

2627 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2629 Support higher-resolution time stamps (Bug#9000).
2630 The time stamps are only nanosecond-resolution at the C level,
2631 since that's the best that any real-world system supports now.
2632 But they are picosecond-resolution at the Lisp level, as that's
2633 easy, and leaves room for future OS improvements.
2635 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2638 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2639 Don't get current time unless it's needed.
2641 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2642 now provides it if it's absent.
2643 (start_atimer): Port to higher-res time stamps.
2644 Check for time stamp overflow. Don't get current time more
2645 often than is needed.
2647 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2648 Include systime.h, not time.h.
2649 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2651 * dired.c: Include stat-time.h.
2652 (Ffile-attributes): File times now have higher resolution.
2654 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2655 (struct image): Timestamp now has higher resolution.
2657 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2658 has at least microseconds now. All uses removed.
2659 (update_frame, update_single_window, update_window, update_frame_1)
2660 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2662 * editfns.c (time_overflow): Now extern.
2663 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2664 (float-time, Fformat_time_string, Fcurrent_time_string)

2668 (decode_time_components, lisp_seconds_argument): New functions.
2669 (make_time): Now static.
2670 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2671 Report an error if the time is invalid, rather than having the caller
2674 * fileio.c: Include <stat-time.h>
2675 (Fcopy_file): Copy higher-resolution time stamps.
2676 Prefer to set the time stamp via a file descriptor if that works.
2677 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2678 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2679 (Fvisited_file_modtime, Fset_visited_file_modtime):
2680 Support higher-resolution time stamps.
2682 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2684 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2686 * image.c (prepare_image_for_display, clear_image_cache)
2687 (lookup_image): Port to higer-resolution time stamps.
2689 * keyboard.c (start_polling, bind_polling_period):
2690 Check for time stamp overflow.
2691 (read_char, kbd_buffer_get_event, timer_start_idle)
2692 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2693 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2694 Port to higher-resolution time stamps. Do not assume time_t is signed.
2695 (decode_timer): New function. Timers are now vectors of length 9,
2696 not 8, to accommodate the picosecond component.
2697 (timer_check_2): Use it.
2699 * nsterm.m (select_timeout, timeval_subtract): Remove.
2700 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2701 as they're a bit more accurate and handle overflow better.
2702 (ns_select): Change prototype to be compatible with pselect.
2703 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2704 * nsterm.h (ns_select): Adjust prototype.
2706 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2707 us-resolution time stamps.
2708 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2710 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2712 * lisp.h (time_overflow): New decl.
2713 (wait_reading_process_output): First arg is now intmax_t, not int,
2714 to accommodate larger waits.
2716 * process.h (struct Lisp_Process.read_output_delay):
2717 Now counts nanoseconds, not microseconds.
2718 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2720 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2721 (wait_reading_process_output):
2722 Port to ns-resolution time stamps.
2723 (Faccept_process_output, wait_reading_process_output):
2724 Check for time stamp overflow. Do not assume time_t is signed.
2725 (select_wrapper): Remove; we now use pselect.
2726 (Fprocess_attributes): Now generates ns-resolution time stamps.
2728 * sysdep.c: Include utimens.h. Don't include utime.h
2729 or worry about struct utimbuf; gnulib does that for us now.
2730 (gettimeofday): Remove; gnulib provides a substitute.
2731 (make_timeval): New function.
2732 (set_file_times): Now sets ns-resolution time stamps.
2733 New arg FD; all uses changed.
2734 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2735 (system_process_attributes):
2736 Now returns ns-resolution time stamp. All uses changed.
2737 Check for time stamp overflow.
2739 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2740 provides a substitute now.
2742 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2743 since it guarantees struct timespec.
2744 (EMACS_TIME): Now struct timespec, so that we can support
2745 ns-resolution time stamps.
2746 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2747 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2748 (EMACS_USECS): Remove.
2749 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2750 so multiply the arg by 1000 before storing it.
2751 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2753 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2754 Port to ns-resolution time stamps.
2755 (EMACS_TIME_NEG_P): Remove; replaced by....
2756 (EMACS_TIME_SIGN): New macro.
2757 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2758 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

2760 (make_timeval, make_lisp_time, decode_time_components): New decls.
2761 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2762 that it mishandled time_t overflow. You can't compare by subtracting!
2763 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2764 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2766 * term.c: Include <sys/time.h>.
2767 (timeval_to_Time): New function, for proper overflow wraparound.
2768 (term_mouse_position, term_mouse_click): Use it.
2770 * undo.c (record_first_change): Support higher-resolution time stamps
2772 (Fprimitive_undo): Use them when restoring time stamps.
2774 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2775 (w32_get_internal_run_time):
2776 Port to higher-resolution Emacs time stamps.
2777 (ltime): Now accepts single 64-bit integer, as that's more convenient
2780 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2782 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2783 for compatibility with pselect. Support ns-resolution time stamps.
2785 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2787 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2788 Check for time stamp overflow, and support ns-resolution time stamps.
2790 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2791 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2792 (timeval_subtract): Remove; no longer needed.
2793 (XTflash, XTring_bell, x_wait_for_event):
2794 Port to ns-resolution time stamps. Don't assume time_t is signed.
2796 2012-06-22 Chong Yidong <cyd@gnu.org>
2798 * xdisp.c (x_consider_frame_title): Revert last change.

2856 gets killed during executing of this function (Bug#11665).

2889 * coding.c (produce_chars): Use ptrdiff_t, not int.
2891 * xterm.c (x_draw_underwave): Check for integer overflow.
2892 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3078 as the union type is for debugging, not for production.
3079 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3080 Use an inline function on all platforms when using the union type,
3081 since this is simpler and 'static inline' can be used portably

3226 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3227 would mishandle a string argument "Xc" if X was a multibyte
3228 character of length 2: it would truncate after X's first byte
3229 rather than including all of X.

3276 and DEFVAR it. Update all users.
3278 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3280 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3282 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3283 Convert pctcpu and pctmem to Lisp float properly.
3284 Let the compiler fold better, as 100.0/0x8000 is exact.
3286 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3288 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3291 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3293 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3295 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3297 For a 'struct window', replace some Lisp_Object fields to
3298 bitfields where appropriate, remove unused fields.
3299 * window.h (struct window): Remove unused 'last_mark_x' and
3300 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3301 change it's type from Lisp_Object to bitfield.
3302 Change type of 'force_start', 'optional_new_start',
3303 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3304 fields from Lisp_Object to bitfield. Adjust users accordingly.
3306 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3308 Pacify gcc -Wdouble-precision when using Xaw.
3309 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3310 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3311 Use 'float' consistently, rather than 'float' in most places
3312 and 'double' in a couple of places.
3314 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3316 * xdisp.c (handle_stop): Detect whether we have overlay strings
3317 loaded by testing it->current.overlay_string_index to be
3318 non-negative, instead of checking whether n_overlay_strings is
3319 positive. (Bug#11587)
3321 2012-05-31 Chong Yidong <cyd@gnu.org>
3323 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3325 * doc.c (Fsubstitute_command_keys): Doc fix.
3327 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3329 * search.c (search_buffer): Remove calls to
3330 r_alloc_inhibit_buffer_relocation, as it is now called by
3331 maybe_unify_char, which was the cause of relocation of buffer text
3334 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3336 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3337 for the duration of call to load_charset, to avoid problems with
3338 callers of maybe_unify_char that access buffer text through C
3341 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3342 decrement the inhibition flag, instead of just setting or
3345 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3347 Remove obsolete '#define static' cruft.
3348 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3349 This #undef was "temporary" in 2000; it is no longer needed
3350 now that '#define static' has gone away.
3351 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3352 (gray_bitmap_bits): Remove; no longer needed.
3353 All uses replaced with definiens.
3354 * xterm.c: Include "bitmaps/gray.xbm".
3356 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3358 Clean up __executable_start, monstartup when --enable-profiling.
3359 The following changes affect the code only when profiling.
3360 * dispnew.c (__executable_start): Rename from safe_bcopy.
3361 Define only on platforms that need it.
3362 * emacs.c: Include <sys/gmon.h> when profiling.
3363 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3364 (__executable_start): Remove decl, since lisp.h does it now.
3365 (safe_bcopy): Remove decl; no longer has that name.
3366 (main): Coalesce #if into single bit of code, for simplicity.
3367 Cast pointers to uintptr_t, since standard libraries want integers
3369 * lisp.h (__executable_start): New decl.
3371 2012-05-31 Glenn Morris <rgm@gnu.org>
3373 * image.c (Fimagemagick_types): Doc fix.
3375 2012-05-30 Jim Meyering <meyering@redhat.com>
3377 * callproc.c (Fcall_process_region): Include directory component
3378 in mkstemp error message (Bug#11586).
3380 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3382 * alloc.c, lisp.h (make_pure_vector): Now static.
3384 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

3391 * lisp.h (Qdefun): Remove.
3392 * lread.c (read1): Tiny simplification.
3394 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3396 Do not create empty overlays with the evaporate property (Bug#9642).
3397 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3398 Bug#9642, but explicitly check that the buffer the overlay would
3399 be moved to is live and rearrange lines to make sure that errors
3400 will not put the overlay in an inconsistent state.
3401 (Fdelete_overlay): Cosmetics.
3403 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3405 * w32term.c (my_bring_window_to_top): New function.
3406 (x_raise_frame): Use handle returned by DeferWindowPos, which
3407 could be different from the original one.
3408 Call my_bring_window_to_top instead of my_set_foreground_window.
3411 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3412 by calling BringWindowToTop.
3414 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3415 (WM_EMACS_END): Increase by one.
3417 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3419 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3420 This avoids undefined behavior that might cause the eassert
3421 to not catch an out-of-range value.
3423 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3425 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3426 Update dependencies.
3428 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3430 * bidi.c (bidi_mirror_char): Fix last change.
3432 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3434 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3435 when referring to sectname field in printf format.
3437 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3439 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3440 Only r_alloc_inhibit_buffer_relocation needed to be added;
3441 the others were already declared.
3443 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3444 before checking whether it's out of range. Put the check inside
3446 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3448 2012-05-27 Ken Brown <kbrown@cornell.edu>
3450 * callproc.c (Fcall_process): Restore a line that was accidentally
3451 commented out in the 2011-02-13 change (bug#11547).
3453 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3455 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3456 defined on ralloc.c.
3458 * buffer.c [REL_ALLOC]: Remove prototypes of
3459 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3460 they are now on lisp.h.
3462 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3464 * search.c (search_buffer): Use it to inhibit relocation of buffer
3465 text while re_search_2 is doing its job, because re_search_2 is
3466 passed C pointers to buffer text. (Bug#11519)
3468 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3471 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3472 state after an additional call to move_it_in_display_line_to, keep
3473 the values of it->max_ascent and it->max_descent found for the
3475 (pos_visible_p): Revert the comparison against bottom_y to what it
3476 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3479 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3481 Fix coding-related core dumps with gcc -ftrapv.
3482 The code was computing A - B, where A and B are pointers, and B is
3483 random garbage. This can lead to core dumps on platforms that
3484 have special pointer registers, and it also leads to core dumps on
3485 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3486 A - B only when B is initialized properly.
3487 * coding.c (coding_set_source, coding_set_destination): Return void.
3488 (coding_change_source, coding_change_destinations): New functions,
3489 with the old behaviors of coding_set_source and coding_set_destination.
3490 All callers that need an offset changed to use these new functions.
3492 2012-05-26 Glenn Morris <rgm@gnu.org>
3494 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3496 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3498 Extend mouse support on W32 text-mode console.
3499 * xdisp.c (draw_row_with_mouse_face):
3500 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3502 * w32console.c: Include window.h.
3503 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3505 (initialize_w32_display): Initialize mouse-highlight data.
3507 * w32inevt.c: Include termchar.h and window.h.
3508 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3509 moves, call note_mouse_highlight. If help_echo changed, call
3510 gen_help_event to produce help-echo message in the echo area.
3511 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3514 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3516 * lread.c (read1): Simplify slightly to avoid an overflow warning
3517 with GCC 4.7.0 on x86-64.
3519 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3521 * bidi.c (bidi_mirror_char): Revert last change: an int is
3522 definitely wide enough here.
3524 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3526 Fix integer width and related bugs (Bug#9874).
3527 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3528 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3529 (string_bytes, check_sblock, allocate_string_data):
3530 (compact_small_strings, Fmake_bool_vector, make_string)
3531 (make_unibyte_string, make_multibyte_string)
3532 (make_string_from_bytes, make_specified_string)
3533 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3534 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3536 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3537 (allocate_pseudovector):
3538 Use int, not EMACS_INT, where int is wide enough.
3539 (inhibit_garbage_collection, Fgarbage_collect):
3540 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3541 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3542 int might not be wide enough.
3543 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3544 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3545 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3546 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3547 (bidi_level_of_next_char, bidi_move_to_visually_next):
3548 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3549 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3550 (Fkill_buffer, Fset_buffer_major_mode)
3551 (advance_to_char_boundary, Fbuffer_swap_text)
3552 (Fset_buffer_multibyte, overlays_at, overlays_in)
3553 (overlay_touches_p, struct sortvec, record_overlay_string)
3554 (overlay_strings, recenter_overlay_lists)
3555 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3556 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3557 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3558 (Foverlay_recenter, last_overlay_modification_hooks_used)
3559 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3560 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3561 (validate_region): Omit unnecessary test for b <= e,
3562 since that's guaranteed by the previous test.
3563 (adjust_overlays_for_delete): Avoid pos + length overflow.
3564 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3565 (report_overlay_modification):
3566 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3567 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3568 Omit pointer cast, which isn't needed anyway, and doesn't work
3569 after the EMACS_INT -> ptrdiff_t change.
3570 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3571 * buffer.h: Adjust decls to match defn changes elsewhere.
3572 (struct buffer_text, struct buffer):
3573 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3574 Use EMACS_INT, not int, where int might not be wide enough.
3575 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3576 not int, to avoid needless 32-bit limit on 64-bit hosts.
3577 (exec_byte_code): Use tighter memory-full test, one that checks
3578 for alloca overflow. Don't compute the address of the object just
3579 before an array, as that's not portable. Use EMACS_INT, not
3580 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3581 * callint.c (Fcall_interactively):
3582 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3583 * callproc.c (call_process_kill, Fcall_process):
3584 Don't assume pid_t fits into an Emacs fixnum.
3585 (call_process_cleanup, Fcall_process, child_setup):
3586 Don't assume pid_t fits into int.
3587 (call_process_cleanup, Fcall_process, delete_temp_file)
3588 (Fcall_process_region):
3589 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3590 (Fcall_process): Simplify handling of volatile integers.
3591 Use int, not EMACS_INT, where int will do.
3592 * casefiddle.c (casify_object, casify_region, operate_on_word)
3593 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3594 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3595 (casify_object): Avoid integer overflow when overallocating buffer.
3596 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3597 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3598 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3599 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3600 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3601 integers are now checked earlier. All uses replaced with XINT.
3603 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3604 For CCL_MapSingle, check that content and value are in int range.
3605 (ccl_driver, Fregister_code_conversion_map):
3606 Check that Vcode_version_map_vector is a vector.
3607 (resolve_symbol_ccl_program): Check that vector header is in range.
3608 Always copy the vector, so that we can check its contents reliably
3609 now rather than having to recheck each instruction as it's being
3610 executed. Check that vector words fit in 'int'.
3611 (ccl_get_compiled_code, Fregister_ccl_program)
3612 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3613 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3614 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3615 contents are in range.
3616 (Fccl_execute_on_string): Check that status is in range.
3617 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3618 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3619 Accept and return EMACS_INT, not int, because callers can pass values
3621 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3622 (multibyte_chars_in_text, parse_str_as_multibyte)
3623 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
3624 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3625 (string_escape_byte8, Fget_byte):
3626 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3627 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3628 avoid mishandling large integers.
3629 * character.h: Adjust decls to match defn changes elsewhere.
3630 * charset.c (load_charset_map_from_file, find_charsets_in_text)
3631 (Ffind_charset_region):
3632 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3633 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
3634 (load_charset_map_from_vector, Fdefine_charset_internal):
3635 Don't assume fixnum fits in int.
3636 (load_charset_map_from_vector, Fmap_charset_chars):
3637 Remove now-unnecessary CHECK_NATNUMs.
3638 (Fdefine_charset_internal): Check ranges here, more carefully.
3639 Don't rely on undefined behavior with signed left shift overflow.
3640 Don't assume unsigned int fits into fixnum, or that fixnum fits
3641 into unsigned int. Don't require max_code to be a valid fixnum;
3642 that's not true for gb10830 4-byte on a 32-bit host. Allow
3643 invalid_code to be a cons, for the same reason. Require code_offset
3644 to be a character. Avoid int overflow if max_char is close
3646 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3647 this is intended anyway and avoids some undefined behavior.
3648 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3649 INDEX_TO_CODE_POINT, as that's what it expects.
3650 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3651 * charset.h (DECODE_CHAR): Return int, not unsigned;
3652 this is what was intended anyway, and it avoids undefined behavior.
3653 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3654 integer-overflow issues.
3655 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3656 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3657 where the argument is EMACS_INT, and this behavior is not intended.
3658 * chartab.c (Fmake_char_table, Fset_char_table_range)
3659 (uniprop_get_decoder, uniprop_get_encoder):
3660 Don't assume fixnum fits in int.
3661 * cmds.c (move_point): New function, that does the gist of
3662 Fforward_char and Fbackward_char, but does so while checking
3663 for integer overflow more accurately.
3664 (Fforward_char, Fbackward_char): Use it.
3665 (Fforward_line, Fend_of_line, internal_self_insert)
3666 (internal_self_insert):
3667 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3668 Fix a FIXME, by checking for integer overflow when calculating
3669 target_clm and actual_clm.
3670 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

4412 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4413 and `display_arg' (bug#9754).
4415 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4417 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4419 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4420 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4422 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4424 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4426 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4427 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4429 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4430 reference to image_cache->refcount.
4431 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4433 2012-05-17 Juri Linkov <juri@jurta.org>
4435 * search.c (Fword_search_regexp, Fword_search_backward)
4436 (Fword_search_forward, Fword_search_backward_lax)
4437 (Fword_search_forward_lax): Move functions to isearch.el
4438 (bug#10145, bug#11381).
4440 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4442 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4444 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4446 * lread.c (init_obarray): Declare Qt and Qnil as special.
4448 2012-05-14 Glenn Morris <rgm@gnu.org>
4450 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4451 Put "libexec" before "bin", for the sake of init_callproc_1.
4453 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4455 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4457 * unexaix.c: Port to more-recent AIX compilers.
4458 (report_error, report_error_1, make_hdr, copy_sym)
4459 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4460 Make arguments const char *, not char *, to avoid violations of C
4461 standard and to fix some AIX warnings reported by Gilles Pion.
4463 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4465 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4466 already have overlays loaded.
4467 (handle_single_display_spec): Before returning without displaying
4468 fringe bitmap, synchronize the bidi iterator with the main display
4469 iterator, by calling iterate_out_of_display_property.
4470 (iterate_out_of_display_property): Detect buffer iteration by
4471 testing that it->string is a Lisp string.
4472 (get_next_display_element): When the current object is exhausted,
4473 and there's something on it->stack, call set_iterator_to_next to
4474 proceed with what's on the stack, instead of returning zero.
4475 (set_iterator_to_next): If called at the end of a Lisp string,
4476 proceed to consider_string_end without incrementing string
4477 position. Don't increment display vector index past the end of
4478 the display vector. (Bug#11417)
4479 (pos_visible_p): Don't report a position visible when move_it_to
4480 stopped at the last line of window, which happens to be scanned
4481 backwards by the bidi iteration. (Bug#11464)
4483 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4485 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4486 and right-margin display specs even if the spec is invalid or we
4487 are on a TTY, and thus unable to display on the fringes.
4488 That's because the text with the property will not be displayed anyway,
4489 so we need to signal to the caller that this is a "replacing"
4490 display spec. This fixes display when the spec is invalid or we
4493 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4495 * unexaix.c (make_hdr): Fix typo in prototype.
4496 This bug broke the build on AIX. Problem reported by Gilles Pion.
4498 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4500 * keyboard.c (kbd_buffer_get_event): Read special events also in
4501 batch mode. (Bug#11415)
4503 2012-05-12 Glenn Morris <rgm@gnu.org>
4505 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4507 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4509 * lisp.mk (lisp): Add newcomment.elc.
4511 2012-05-12 Glenn Morris <rgm@gnu.org>
4513 * Makefile.in (MKDIR_P): New, set by configure.
4514 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4516 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4518 Remove unused function hourglass_started.
4519 * dispextern.h (hourglass_started):
4520 * w32fns.c (hourglass_started):
4521 * xdisp.c (hourglass_started): Remove.
4523 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4525 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4526 Update dependencies.
4528 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4530 * xgselect.c (xg_select): Put maxfds+1 into a var.
4531 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4533 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4535 2012-05-10 Dave Abrahams <dave@boostpro.com>
4537 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4538 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4540 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4542 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4543 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4544 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4545 Initialize xd_registered_buses.
4547 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4549 Untag more efficiently if USE_LSB_TAG.
4550 This is based on a proposal by YAMAMOTO Mitsuharu in
4551 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4552 For an admittedly artificial (nth 8000 longlist) benchmark on
4553 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4554 Emacs's overall text size by 1%.
4555 * lisp.h (XUNTAG): New macro.
4556 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4557 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4558 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4559 * eval.c (Fautoload):
4560 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4561 * frame.h (XFRAME): Use XUNTAG.
4563 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4564 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4565 Remove unportable assumptions about print widths of types like
4567 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4568 intptr_t when converting between pointer and integer, to avoid GCC
4569 warnings about wrong width.
4571 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4573 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4574 stack for each reader_thread, instead of defaulting to 8MB
4575 determined by the linker. This avoids failures in creating
4576 subprocesses on Windows 7, see the discussion in this thread:
4577 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4579 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4581 Fix up display of the *Minibuf-0* buffer in the mini window.
4582 * keyboard.c (read_char): Don't clear the echo area if there's no
4584 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4585 contents of *Minibuf-0*) if there's no message displayed in its stead.
4587 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4589 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4592 2012-05-06 Chong Yidong <cyd@gnu.org>
4594 * lisp.mk (lisp): Update.
4596 2012-05-05 Jim Meyering <meyering@redhat.com>
4598 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4600 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4602 * data.c (PUT_ERROR): New macro.
4603 (syms_of_data): Use it. Add new error type `user-error'.
4604 * undo.c (user_error): New function.
4605 (Fprimitive_undo): Use it.
4606 * print.c (print_error_message): Adjust print style for `user-error'.
4607 * keyboard.c (user_error): New function.
4608 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4610 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4612 Do not limit current-time-string to years 1000..9999.
4613 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4614 (Fcurrent_time_string): Support any year that is supported by the
4615 underlying localtime representation. Don't use asctime, as it
4616 has undefined behavior for years outside the range -999..9999.
4618 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4620 Fix race conditions involving setenv, gmtime, localtime, asctime.
4621 Without this fix, interrupts could mess up code that uses these
4622 nonreentrant functions, since setting TZ invalidates existing
4623 tm_zone or tzname values, and since most of these functions return
4624 pointers to static storage.
4625 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4626 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4627 Grow the critical sections to include not just invoking
4628 localtime/gmtime, but also accessing these functions' results
4629 including their tm_zone values if any, and any related TZ setting.
4630 (format_time_string): Last arg is now struct tm *, not struct tm **,
4631 so that the struct tm is saved in the critical section.
4632 All callers changed. Simplify allocation of initial buffer, partly
4633 motivated by the fact that memory allocation needs to be outside
4634 the critical section.
4636 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4638 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4639 with RESET_INTERVAL.
4641 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4642 Remove duplicated buffer name initialization.
4644 2012-05-02 Jim Meyering <jim@meyering.net>
4646 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4648 * xfns.c (x_window): Use xstrdup (Bug#11375).
4650 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4652 * xdisp.c (pos_visible_p): If already at a newline from the
4653 display string before the 'while' loop, don't walk back the glyphs
4654 from it3.glyph_row. Solves assertion violation when the display
4655 string begins with a newline (egg.el). (Bug#11367)
4657 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4659 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4662 2012-05-01 Glenn Morris <rgm@gnu.org>
4664 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4665 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4666 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4667 All were removed before 23.1.
4669 * dispnew.c: Remove HAVE_LIBNCURSES test;
4670 it is always true on relevant platforms.
4672 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4673 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4675 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4677 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4679 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4680 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4683 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4685 Do not avoid creating empty evaporating overlays (Bug#9642).
4686 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4687 That is, do not delete an evaporating overlay if it becomes
4688 empty after its bounds are adjusted to fit within its buffer.
4689 This fix caused other problems, and I'm reverting it until we get
4690 to the bottom of them.
4692 2012-04-27 Chong Yidong <cyd@gnu.org>
4694 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4696 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4698 * xdisp.c (pos_visible_p): If the window start position is beyond
4699 ZV, start the display from buffer beginning. Prevents assertion
4700 violation in init_iterator when the minibuffer window is scrolled
4703 * window.c (window_scroll_pixel_based): Likewise.
4705 2012-04-27 Chong Yidong <cyd@gnu.org>
4707 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4709 2012-04-27 Glenn Morris <rgm@gnu.org>
4711 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4712 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4714 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4716 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4717 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4719 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4721 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4722 display element, check also the underlying string or buffer
4723 character. (Bug#11341)
4725 * w32menu.c: Include w32heap.h.
4726 (add_menu_item): If the call to AppendMenuW (via
4727 unicode_append_menu) fails, disable Unicode menus only if we are
4728 running on Windows 9X/Me.
4730 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4732 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4733 (xgetint): Add missing shift for LSB tags.
4735 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4737 * keyboard.c (read_char): Don't wipe echo area for select window
4738 events: These might get delayed via `mouse-autoselect-window'
4741 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4743 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4744 manipulation of :loaded-from data.
4746 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4748 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4749 now a cons (bug#11311).
4751 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4753 Do not create empty overlays with the evaporate property (Bug#9642).
4754 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4755 if it becomes empty after its bounds are adjusted to fit within
4756 its buffer. Without this fix, in a nonempty buffer (let ((o
4757 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4758 yields an empty overlay that has the evaporate property, which is
4759 not supposed to happen.
4761 Fix minor GTK3 problems found by static checking.
4762 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4763 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4764 (struct _EmacsFixedClass, emacs_fixed_get_type):
4765 Move decls here from emacsgtkfixed.h, since they needn't be public.

4767 (emacs_fixed_class_init): Omit unused local.
4768 (emacs_fixed_child_type): Remove; unused.

4771 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4772 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4773 (EMACS_FIXED_GET_CLASS): Remove; unused.
4774 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4776 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4777 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4779 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4781 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4782 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4783 (__malloc_size_t, __malloc_ptrdiff_t):
4784 Remove. All uses removed, replaced by the definiens if needed,
4785 since we can assume C89 or better now.
4786 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4787 (protect_malloc_state, align, get_contiguous_space)
4788 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4794 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4795 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4796 Define using prototypes, not old style.
4797 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4798 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4799 (align): Don't assume that signed integer overflow wraps around.
4800 Omit unused local var.
4801 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4802 (_free_internal_nolock, memalign, mallochook, reallochook):
4803 Omit no-longer-needed casts.
4804 (valloc): Use getpagesize, not __getpagesize.
4805 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
4806 (struct hdr): The 'magic' member is now size_t, not unsigned long.
4808 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4810 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
4812 Move functions from C to Lisp. Make non-blocking method calls
4813 the default. Implement further D-Bus standard interfaces.
4815 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
4816 (QCdbus_request_name_allow_replacement)
4817 (QCdbus_request_name_replace_existing)

4855 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4857 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
4858 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
4859 Do not assume ptrdiff_t is the same width as 'int'.
4861 * alloc.c: Handle unusual debugging option combinations.
4862 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4863 since the two debugging options are incompatible.
4864 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4866 (mem_init, mem_insert, mem_insert_fixup):
4867 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
4868 (NEED_MEM_INSERT): Remove; no longer needed.
4870 2012-04-22 Leo Liu <sdl.web@gmail.com>

4897 * print.c (print_preprocess): Only check print_depth if print-circle
4899 (print_object): Check for cycles even when print-circle is nil and
4900 print-gensym is t, but only check print_depth if print-circle is nil.
4902 2012-04-20 Chong Yidong <cyd@gnu.org>
4904 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4905 set the status to "failed" and ensure that sentinel is run.
4907 2012-04-20 Glenn Morris <rgm@gnu.org>

4918 row, return zero immediately.
4919 (try_cursor_movement): If inside continuation line, don't back up
4920 farther than the first row after the header line, if any.
4921 Don't consider the header-line row as "partially visible", even if
4922 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4924 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4959 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
4960 New extern decls, to avoid calling undeclared functions.
4961 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4962 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4963 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4964 (NEED_MEM_INSERT): New macro.
4965 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4966 Remove one incorrect comment and fix another.

4980 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4981 Remove decls. This fixes an "It stinks!".

4985 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4987 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5000 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5001 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5002 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5003 * s/netbsd.h, s/sol2-6.h:
5004 Remove definition of GC_MARK_STACK, since the default now works.
5005 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5006 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5007 no longer the default.
5008 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5010 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5012 * lread.c (lisp_file_lexically_bound_p):

5033 2012-04-11 Daniel Colascione <dancol@dancol.org>
5035 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5036 against is gone. It's better to use vfork now so that when Cygwin
5037 gains a new, working vfork, we use it automatically (bug#10398).
5039 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5057 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5059 * w32.c (w32_delayed_load): Record the full path of the library
5060 being loaded (bug#10424).
5062 2012-04-09 Glenn Morris <rgm@gnu.org>
5064 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5065 not just in the obarray, before snarfing them. (Bug#11036)
5067 * Makefile.in ($(leimdir)/leim-list.el):
5068 Pass EMACS rather than BUILT_EMACS.

5077 Add convenience `GNUTLS_LOG2i' macro.
5079 * gnutls.c (gnutls_log_function2i): Convenience log function.
5080 (emacs_gnutls_read): Use new log functions,
5081 `gnutls_handshakes_tried' process member, and

5083 attempts per process (connection).
5085 2012-04-09 Chong Yidong <cyd@gnu.org>
5087 * eval.c (Fuser_variable_p, user_variable_p_eh)

5092 * minibuf.c (Fread_variable): Callers changed.
5094 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5096 * xdisp.c (set_cursor_from_row): If the display string appears in
5097 the buffer at position that is closer to point than the position
5098 after the display string, display the cursor on the first glyph of
5099 the display string. Fixes cursor display when a 'display' text
5100 property immediately follows invisible text. (Bug#11094)
5102 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5104 composite.c: use 'double' consistently
5105 * composite.c (get_composition_id): Use 'double' consistently
5106 instead of converting 'float' to 'double' and vice versa; this is
5107 easier to understand and avoids a GCC warning.
5109 2012-04-09 Glenn Morris <rgm@gnu.org>
5111 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5112 preparation for dumping it with emacs. (Bug#4789)

5134 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5135 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5136 objects, as mark_maybe_pointer will catch them otherwise.
5137 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5138 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5140 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5142 Fix typo that broke non-Windows builds.
5143 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5154 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5155 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5156 [!WINDOWSNT]: New macros.
5157 (init_libxml2_functions, libxml2_loaded_p): New functions.
5158 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5159 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5160 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5161 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5163 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5164 Call init_libxml2_functions before calling libxml2 functions.
5165 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5167 * emacs.c: Don't include libxml/parser.h.
5168 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5169 xmlCleanupParser directly.
5171 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5173 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5175 * indent.c (Fvertical_motion): If there is a display string at
5176 point, use it.vpos to compute how many lines to backtrack after

5179 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5181 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5182 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5183 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5184 macros related to unification of CJK characters. For the details,
5185 see the discussion following the message here:
5186 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5188 2012-04-04 Chong Yidong <cyd@gnu.org>
5190 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5192 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5194 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5202 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5204 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5205 position we get to after a call to move_it_to fails the
5206 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5207 only if we wind up in a string from display property. (Bug#11063)
5209 * window.c (Fdelete_other_windows_internal): Invalidate the row
5210 and column information about mouse highlight, so that redisplay
5211 restores it after reallocating the glyph matrices. (Bug#7464)
5213 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5214 string comes from a `display' text property, use the buffer
5215 position of that property as if we actually saw that position in
5217 (move_it_by_lines): Remove the assertion that
5218 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5219 violated when there's a before-string at the beginning of a line.
5222 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5224 * xdisp.c (append_space_for_newline): If the default face was
5225 remapped, use the remapped face for the appended newline.
5226 (extend_face_to_end_of_line): Use the remapped default face for
5227 extending the face to the end of the line.
5228 (display_line): Call extend_face_to_end_of_line when the default
5229 face was remapped. (Bug#11068)
5231 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5233 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5253 handle-select-window too (Bug#8996).
5255 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5257 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5259 2012-03-25 Kenichi Handa <handa@m17n.org>
5261 * dispextern.h (struct glyph): Change the bit length of
5262 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5264 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5266 * s/ms-w32.h (tzname): Include time.h before redirecting to
5267 _tzname. Fixes the MSVC build. (Bug#9960)
5269 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5271 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5274 * xterm.c (XTread_socket): Only modify handling_signal if

5277 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5279 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5280 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5281 when fetching a multibyte character consumes more bytes than
5282 CHAR_BYTES returns, due to unification of CJK characters in
5283 string_char. (Bug#11073)
5285 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5287 * process.c (wait_reading_process_output): Handle pty disconnect
5288 by refraining from sending oneself a SIGCHLD (bug#10933).

5299 2012-03-21 Chong Yidong <cyd@gnu.org>
5301 * xfaces.c (Vface_remapping_alist): Doc fix.
5303 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5305 * w32proc.c (Fw32_set_console_codepage)
5306 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5317 it fit in a valid range (Bug#11003).
5319 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5321 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5322 that is not from display property, accept the row as a "cursor
5323 row" if one of the string's character has a non-nil `cursor'
5324 property. Fixes cursor positioning when there are newlines in
5325 overlay strings, e.g. in icomplete.el. (Bug#11035)
5327 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5329 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5331 2012-03-12 Chong Yidong <cyd@gnu.org>
5333 * eval.c (inhibit_lisp_code): Rename from
5334 inhibit_window_configuration_change_hook; move from window.c.
5336 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5337 * window.c (run_window_configuration_change_hook)
5338 (syms_of_window): Callers changed.

5358 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5361 2012-03-03 Glenn Morris <rgm@gnu.org>
5363 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

5376 * buffer.c (buffer-list-update-hook): Doc fix.
5378 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5381 push_it before setting up the iterator for the first overlay
5382 string, even if we have an empty string loaded.
5383 (next_overlay_string): If there's an empty string on the iterator
5384 stack, pop the stack. (Bug#10903)
5386 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5388 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5389 Suggested by Stefan Monnier in
5390 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5391 * alloc.c (widen_to_Lisp_Object): New static function.
5392 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5393 and widening them to Lisp_Objects. This would work even if
5394 USE_LSB_TAG is defined and wide integers are used, which might
5395 happen in a future version of Emacs.
5397 2012-02-25 Chong Yidong <cyd@gnu.org>
5399 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

5415 (unwind_create_frame_1): New helper function.
5417 * window.c (inhibit_window_configuration_change_hook): New var.
5418 (run_window_configuration_change_hook): Obey it.
5419 (syms_of_window): Initialize it.
5421 2012-02-22 Chong Yidong <cyd@gnu.org>

5436 when computing $valmask.
5438 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5439 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5440 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5441 It's useless in that case, and it can cause problems on hosts
5442 that allocate halves of EMACS_INT values separately.
5443 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5444 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5445 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5446 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5447 it avoids undefined behavior on hosts where shifting right by more
5448 than the word width has undefined behavior.
5450 2012-02-19 Chong Yidong <cyd@gnu.org>
5452 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5453 (Funhandled_file_name_directory, Ffile_name_as_directory)

5472 2012-02-15 Chong Yidong <cyd@gnu.org>
5474 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5475 marked as special. Also, starting docstrings with * is obsolete.

5492 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5493 as that creates a dangerous corner case.
5495 * window.c (Fdelete_window_internal): Invalidate the mouse
5496 highlight (Bug#9904).
5498 2012-02-12 Glenn Morris <rgm@gnu.org>

5528 2012-02-07 Chong Yidong <cyd@gnu.org>
5530 * buffer.c (Fbuffer_local_variables)
5531 (buffer_lisp_local_variables): Handle unbound vars correctly;
5532 don't let Qunbound leak into Lisp.
5534 2012-02-07 Glenn Morris <rgm@gnu.org>
5536 * image.c (Fimagemagick_types): Doc fix.
5538 * image.c (imagemagick-render-type): Change it from a lisp object

5571 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5573 Handle overflow when computing char display width (Bug#9496).
5574 * character.c (char_width): Return EMACS_INT, not int.
5575 (char_width, c_string_width): Check for overflow when
5576 computing the width; this is possible now that individual
5577 characters can have unbounded width. Problem introduced
5578 by merge from Emacs 23 on 2012-01-19.
5580 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

5609 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5610 first 2 arguments are identical. This makes inserting large

5720 (Fmake_directory_internal): Use it.

6232 is set, removing the need for VIRT_ADDRESS_VARIES.

6236 to 4 (xorl, subq, cmpq, setbe).
6237 * alloc.c (pure): Always extern now, since that's the

6250 behave as if the cursor position were at the window margin.
6252 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6253 and the cursor position is out of bounds, behave as if the cursor
6254 position were at the window margin. (Bug#10075)

6281 (compute_line_metrics): Call row_hash, instead of computing the
6284 * dispnew.c (verify_row_hash): Call row_hash for computing the
6285 hash code of a row, instead of duplicating code from xdisp.c.
6287 * dispextern.h (row_hash): Add prototype.
6289 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6291 * frame.c (delete_frame): Don't delete the terminal when the last

6319 occurrences of window_nest to window_combination_limit.
6321 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6323 * image.c (imagemagick_load_image): Fix typo.
6325 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6327 * xdisp.c (display_line): Move the call to
6328 highlight_trailing_whitespace before the call to
6329 compute_line_metrics, since the latter needs to see the final
6330 faces of all the glyphs to compute ROW's hash value.

6395 The trivial performance wins aren't worth the portability hassles; see
6396 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6398 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6475 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6476 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6477 * intervals.c (adjust_intervals_for_insertion)
6478 (adjust_intervals_for_deletion): Now extern, because otherwise the
6479 extern inline functions 'offset_intervals' couldn't refer to it.
6480 (static_offset_intervals): Remove.
6481 (offset_intervals): Rewrite using the old contents of
6482 static_offset_intervals. The old version didn't conform to C99
6483 because an extern inline function contained a reference to an

6506 (Fwindow_vscroll): Doc fix.
6507 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default

6799 This fixes a bug when the time zone name contains characters that
6800 need converting from the system time locale to Emacs internal format.
6801 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6802 that patch fixed format-time-string to do the conversion, but
6803 I forgot to fix current-time-zone.
6804 (format_time_string): New function, containing most of
6805 what Fformat_time_string used to contain.
6806 (Fformat_time_string): Rewrite in terms of format_time_string.
6807 This doesn't change this function's behavior.
6808 (current-time-zone): Rewrite to use format_time_string.
6809 This fixes the bug reported by Michael Schierl in
6810 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6811 Jason Rumney's 2007-06-07 change worked around this bug, but
6813 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6815 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6817 * xdisp.c (start_display): If the character at POS is displayed
6818 via a display vector, reset IT->current.dpvec_index to zero.
6819 (try_window_reusing_current_matrix): If a line ends in a display
6820 vector or the next line starts in a display vector, continue
6821 redrawing the window even though the character position of
6822 start_row was reached.
6825 2011-10-18 Chong Yidong <cyd@gnu.org>
6827 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6828 with nobreak-char-display too.
6830 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6832 Fix part 3 of bug#9771.
6833 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6834 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6835 non-neutral characters if the current character is a paragraph
6836 separator (a.k.a. Newline). This avoids running the same
6837 expensive loop twice, once when we consume the preceding newline
6838 and the other time when the line actually needs to be displayed.
6839 Avoid the loop when we see neutrals on the base embedding level
6840 following a character whose directionality is the same as the
6841 paragraph's. This avoids running the expensive loop when a line
6842 ends in a long sequence of neutrals, like control characters.
6843 Add assertion against STRONG_AL type. Slightly rearrange code
6844 that determines the type of a neutral given the first non-neutral
6846 (bidi_level_of_next_char): Set next_en_pos to zero when
6847 invalidating its info.
6849 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6851 * xdisp.c (push_display_prop): Determine whether to record string
6852 or buffer position by IT->string, not by IT->method. Allow
6853 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6854 (move_it_vertically_backward): Don't look for character position
6855 immediately after the newline when in a continuation line.
6858 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6860 * window.c (coordinates_in_window): Rewrite and delabelize
6861 vertical border check. (Bug#5357) (Bug#9618)
6863 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6865 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6866 errors in XSetWindowBorder (bug#9310).
6868 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6870 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6871 avoid crash when xmalloc overrun checking is enabled.
6873 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6875 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6876 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6877 cursor motion with <left> and <right> arrow keys.
6879 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6880 some callers set that themselves.
6882 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6884 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6885 display string and the previous row comes from the same string and
6886 is empty. (Bug#9739) (Bug#9738)
6888 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6890 * doc.c (get_doc_string): Encode file name (bug#9735).
6892 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6894 * bidi.c (bidi_level_of_next_char):
6895 * xdisp.c (get_visually_first_element): Remove old incorrect
6896 comments regarding the Unicode Line Separator character.
6898 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6900 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6902 * alloc.c (Fgc_status): Do not access beyond zombies array
6903 boundary if nzombies > MAX_ZOMBIES.
6904 * alloc.c (dump_zombies): Add missing format specifier.
6906 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6908 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6909 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6911 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6912 Some packages use them to denote characters with modifiers.
6914 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6916 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6917 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6918 matching a pp-number. Rename parameter var to var1.
6920 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6922 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6924 2011-10-08 Glenn Morris <rgm@gnu.org>
6926 * callint.c (Fcall_interactively): Give a more explicit error for the
6927 'c' case with a non-character input. (Bug#8479)
6929 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6931 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6933 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6934 lines that are hscrolled on the left.
6936 * dispnew.c (buffer_posn_from_coords): Account for a possible
6937 presence of header-line. (Bug#4426)
6939 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6941 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6942 Don't advertise functionality which we discourage or doesn't work.
6944 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6946 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6947 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6948 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6949 this makes Emacs dump core during garbage collection on rare
6950 occasions. sizeof is obviously inferior to offsetof here, so
6951 stick with offsetof.
6952 (GC_POINTER_ALIGNMENT): New macro.
6953 (mark_memory): Omit 3rd (offset) arg; caller changed.
6954 Don't assume EMACS_INT alignment is the same as pointer alignment.
6956 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6958 * keyboard.c (read_key_sequence_remapped): New var.
6959 (read_key_sequence): Compute remapping in the right buffer.
6960 (command_loop_1): Use read_key_sequence's remapping directly.
6962 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6964 * dired.c (file_name_completion): Don't expand file name.
6965 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6966 before checking file name handler.
6968 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6969 they've been requested explicitly (bug#9591).
6971 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6973 * keymap.c (Fsingle_key_description): Use make_specified_string
6974 instead of build_string to build string from push_key_description.
6977 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6979 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6980 This fixes a Y2038 bug on 64-bit hosts.
6981 * buffer.c (reset_buffer):
6982 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6983 (Fclear_buffer_auto_save_failure):
6984 Use 0, not -1, to represent an unset failure time, since time_t
6985 might not be signed.
6987 Remove dependency on glibc malloc internals.
6988 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6989 Move back here from lisp.h, but with their new implementations.
6990 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6991 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6992 * charset.c (charset_table_init): New static var.
6993 (syms_of_charset): Use it instead of xmalloc. This removes a
6994 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6995 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6996 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6997 Move back to alloc.c.
6998 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6999 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7001 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7003 * nsterm.m (windowDidResize): Call x_set_window_size only when
7004 ns_in_resize is true. Otherwise set pixelwidth/height and
7005 call change_frame_size (Bug#9628).
7007 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7009 Port --enable-checking=all to Fedora 14 x86-64.
7010 * charset.c (syms_of_charset): Also account for glibc malloc's
7011 internal overhead when calculating the initial malloc maximum.
7013 Port --enable-checking=all to Fedora 14 x86.
7014 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7016 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7017 (overrun_check_realloc, overrun_check_free):
7018 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7019 That way, xmalloc returns a properly-aligned pointer even if
7020 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7021 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7022 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7023 into account when calculating the initial malloc maximum.
7024 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7025 Move here from alloc.c, so that charset.c can use it too.
7026 Properly align; the old code wasn't right for common 32-bit hosts
7027 when configured with --enable-checking=all.
7028 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7029 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7031 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7033 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7036 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7038 * xdisp.c (compute_display_string_end): If there's no display
7039 string at CHARPOS, return -1.
7041 * bidi.c (bidi_fetch_char): When compute_display_string_end
7042 returns a negative value, treat the character as a normal
7043 character not covered by a display string. (Bug#9624)
7045 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7047 * lread.c (Fread_from_string): Fix typo in docstring.
7049 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7051 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7052 newline, reseat the iterator instead of bidi-iterating there one
7053 character at a time. (Bug#9610)
7054 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7055 TO_CHARPOS if the bidi iterator is at base embedding level.
7057 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7059 * lread.c (readevalloop): Use correct code for NBSP.
7060 (read1): Likewise. (Bug#9608)
7062 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7064 * dbusbind.c (Fdbus_register_signal): When service is not
7065 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7067 2011-09-25 Glenn Morris <rgm@gnu.org>
7069 * buffer.c (truncate-lines): Doc fix.
7071 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7073 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7074 (Fset_window_next_buffers): Doc fix.
7076 2011-09-24 Glenn Morris <rgm@gnu.org>
7078 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7080 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7082 Fix minor problems found by static checking.
7083 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7084 * indent.c (Fvertical_motion): Fix == vs = typo.
7086 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7088 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7089 Default value is now t. Doc fix.
7091 * indent.c (Fvertical_motion): Compute and apply the overshoot
7092 logic when moving up, not only when moving down. Fix the
7093 confusing name and values of the it_overshoot_expected variable;
7094 logic changes accordingly. (Bug#9254) (Bug#9549)
7096 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7097 CHARPOS is covered by a display string which includes newlines.
7098 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7099 is covered by a display string with embedded newlines.
7101 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7103 * dbusbind.c (Fdbus_register_signal): Add match rule to
7104 Vdbus_registered_objects_table. (Bug#9581)
7105 (Fdbus_register_method, Vdbus_registered_objects_table):
7108 2011-09-24 Jim Meyering <meyering@redhat.com>
7110 do not ignore write error for any output size
7111 The previous change was incomplete.
7112 While it makes emacs --batch detect the vast majority of stdout
7113 write failures, errors were still ignored whenever the output size is
7114 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7115 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7116 && echo FAIL: ignored write error
7117 FAIL: ignored write error
7118 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7119 && echo FAIL: ignored write error
7120 FAIL: ignored write error
7121 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7123 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7125 * emacs.c (Fkill_emacs): In noninteractive mode exit
7126 non-successfully if a write error occurred on stdout. (Bug#9574)
7128 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7130 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7133 * dispextern.h (struct it): Update the comment documenting what
7136 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7138 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7139 a display string, extend search for cursor position to end of row.
7140 (find_row_edges): If the row ends in a newline from a display
7141 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7142 Handle the case of a display string with multiple newlines.
7143 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7144 non-empty line. Fixes confusing cursor motion with arrow keys at
7145 the beginning of a line that starts with whitespace.

7154 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7157 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7159 * xdisp.c (display_line): Record maximum and minimum buffer
7160 positions even if no glyphs were produced (e.g., by a zero-width
7161 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7162 buffer positions that will be removed from the glyph row because
7164 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7165 column is beyond frame width: don't subtract 1 "pixel" when
7166 computing width of the stretch.
7167 (reseat_at_next_visible_line_start): Undo the change made on
7168 2011-09-17 that saved paragraph information and restored it after
7169 the call to `reseat'. (Bug#9545)
7171 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7173 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7174 and turn window cursor on if cleared (Bug#9415).

7187 Fix minor problem found by static checking.
7188 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7189 initialized, to pacify gcc -Wuninitialized.
7191 * fileio.c: Report proper errno when syscall falls.
7192 (Finsert_file_contents): Save and restore errno,
7193 so that report_file_error outputs the correct diagnostic.
7194 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7196 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7198 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7200 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7202 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7203 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7205 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7207 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7208 about the current paragraph and restore it after the call to reseat.
7210 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7211 (bidi_find_paragraph_start): Search back for paragraph beginning
7212 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7213 (bidi_move_to_visually_next): Only trigger paragraph-related
7214 computations when the last character is a newline or at EOB, not
7215 just any NEUTRAL_B. (Bug#9470)
7217 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7218 truncated lines if point is covered by a display string. (Bug#9524)
7220 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7222 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7223 (cons_to_x_long): New function.
7224 (lisp_data_to_selection_data): Use it. Correct the test for
7225 short-versus-long data; it was negated. Break out of vector
7226 loop, for efficiency, when a long datum is discovered.
7228 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7230 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7232 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7234 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7235 GCC PR/17406) by declaring this function with external scope.
7237 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

7258 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7259 This occurs when processing a multibyte format.
7260 Problem reported by Wolfgang Jenker.
7262 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7264 * xdisp.c (try_cursor_movement): Only check for exact match if
7265 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7267 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7269 Remove unused external symbols.
7270 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7271 * xdisp.c (calc_pixel_width_or_height): Now static.
7272 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7273 * indent.c (check_display_width):
7274 * w32term.c: Fix comment to match code.
7275 * xterm.c, xterm.h (x_catching_errors): Remove.
7277 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7279 * xselect.c: Use signed conversions more consistently (Bug#9498).
7280 (selection_data_to_lisp_data): Assume incoming selection data are
7281 signed integers, not unsigned. This is to be consistent with
7282 outgoing selection data, which was modified to use signed integers
7283 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7284 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7285 expects long, not unsigned long.
7287 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7289 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7290 computation of loop end. Reported by Johan Bockgård
7293 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7295 * frame.c (Fother_visible_frames_p): Function deleted.
7297 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7299 * indent.c (compute_motion): Process display vector front to back
7300 rather than the other way around. (Bug#2496)
7302 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7304 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7306 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7308 * minibuf.c (Fread_from_minibuffer): Doc fix.
7310 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7312 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7313 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7315 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7317 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7318 value for non-existent files.
7320 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7322 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7323 set its "size" to -1. This will set the modtime_size field of
7324 the corresponding buffer to -1, which is what
7325 verify-visited-file-modtime expects for files that do not exist.
7328 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7330 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7332 * lisp.h: ... from here. push_key_description is no longer
7333 defined in keyboard.c, so its declaration should not be in
7334 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7335 logically belongs with push_key_description.
7337 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7339 * buffer.h: Include <sys/types.h> instead of <time.h>.
7340 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7341 Problem reported by Herbert J. Skuhra.
7343 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7345 * xml.c (parse_region): Make the parsing work for
7346 non-comment-starting XML files again (bug#9144).
7348 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7350 * image.c (gif_load): Fix calculation of bottom and right corner.
7353 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7355 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7356 redisplay in small windows.
7358 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7360 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7362 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7364 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7365 Operate on live windows only.
7367 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7369 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7371 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7373 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7374 only under bidi iteration.
7376 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7378 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7380 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7382 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7383 Without this fix, the command to link temacs failed due to an
7384 undefined symbol __builtin_isnan. This is because
7385 /usr/include/iso/math_c99.h #defines isnan(x) to
7386 __builtin_isnan(x), but the bundled gcc, which identifies itself
7387 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7389 * floatfns.c (isnan): #undef, and then #define to a clone of
7391 (Fisnan): Always define, since it's always available now.
7392 (syms_of_floatfns): Always define isnan at the Lisp level.
7394 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7396 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7398 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7400 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7401 The previous code assumed that file offsets (off_t values) fit in
7402 EMACS_INT variables, which is not true on typical 32-bit hosts.
7403 The code messed up by falsely reporting buffer overflow in cases
7404 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7405 when "big" contains more than 2**29 bytes, even though this
7406 inserts just one byte and does not overflow the buffer.
7407 (Finsert_file_contents): Store file offsets as off_t
7408 values, not as EMACS_INT values. Check for overflow when
7409 converting between EMACS_INT and off_t. When checking for
7410 buffer overflow or for overlap, take the offsets into account.
7411 Don't use EMACS_INT for small values where int suffices.
7412 When checking for overlap, fix a typo: ZV was used where
7413 ZV_BYTE was intended.
7414 (Fwrite_region): Don't assume off_t fits into 'long'.
7415 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7417 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7419 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7421 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7423 sprintf-related integer and memory overflow issues (Bug#9412).
7425 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7426 (esprintf, exprintf, evxprintf): New functions.
7427 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7428 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7429 (modify_event_symbol): Do not assume that the length of
7430 name_alist_or_stem is safe to alloca and fits in int.
7431 (Fexecute_extended_command): Likewise for function name and binding.
7432 (Frecursion_depth): Wrap around reliably on integer overflow.
7433 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7434 since some callers pass EMACS_INT values.
7435 (Fsingle_key_description): Don't crash if symbol name contains more
7436 than MAX_ALLOCA bytes.
7437 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7438 (get_minibuffer): Arg is now EMACS_INT, not int.
7439 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7440 (esprintf, exprintf, evxprintf): New decls.
7441 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7443 * dbusbind.c (signature_cat): New function.
7444 (xd_signature, Fdbus_register_signal):
7445 Do not overrun buffer; instead, report string overflow.
7447 * dispnew.c (add_window_display_history): Don't overrun buffer.
7448 Truncate instead; this is OK since it's just a log.
7450 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7451 even if the time zone offset is outlandishly large.
7452 Don't mishandle offset == INT_MIN.
7454 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7455 when creating daemon; the previous buffer-overflow check was incorrect.
7457 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7458 which has the guts of the old verror function.
7460 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7461 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7463 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7464 (font_unparse_xlfd): Don't blindly alloca long strings.
7465 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7466 fits in int, when using sprintf. Use single snprintf to count
7467 length of string rather than counting it via multiple sprintfs;
7468 that's simpler and more reliable.
7469 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7470 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7471 sprintf, in case result does not fit in int.
7473 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7474 (fontset_from_font): Print it.
7476 * frame.c (tty_frame_count): Now printmax_t, not int.
7477 (make_terminal_frame, set_term_frame_name): Print it.
7478 (x_report_frame_params): In X, window IDs are unsigned long,
7479 not signed long, so print them as unsigned.
7480 (validate_x_resource_name): Check for implausibly long names,
7481 and don't assume name length fits in 'int'.
7482 (x_get_resource_string): Don't blindly alloca invocation name;
7483 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7486 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7487 (xg_check_special_colors, xg_set_geometry):
7488 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7490 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7491 Use esprintf, not sprintf, in case result does not fit in int.
7493 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7494 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7495 it as a large positive number.
7496 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7497 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7499 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7500 in case result does not fit in int.
7502 * print.c (float_to_string): Detect width overflow more reliably.
7503 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7504 buffer overrun. Don't assume list length fits in 'int'. Treat
7505 print length of 0 as 0, not as infinity; to be consistent with other
7506 uses of print length in this function. Don't overflow print length
7507 index. Don't assume hash table size fits in 'long', or that
7508 vectorlike size fits in 'unsigned long'.
7510 * process.c (make_process): Use printmax_t, not int, to format
7511 process-name gensyms.
7513 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7515 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7516 to avoid potential buffer overrun.
7518 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7519 if X resource line is longer than 512 bytes.
7521 * xfns.c (x_window): Make sprintf buffer a bit bigger
7522 to avoid potential buffer overrun.
7524 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7526 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7528 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7530 Integer overflow fixes for scrolling, etc.
7531 Without these, Emacs silently mishandles large integers sometimes.
7532 For example, "C-u 4294967297 M-x recenter" was treated as if
7533 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7535 * xdisp.c (try_window_id): Check Emacs fixnum range before
7536 converting to 'int'.
7538 * window.c (window_scroll_line_based, Frecenter):
7539 Check that an Emacs fixnum is in range before assigning it to 'int'.
7540 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7541 values converted from Emacs fixnums.
7542 (Frecenter): Don't wrap around a line count if it is out of 'int'
7543 range; instead, treat it as an extreme value.
7544 (Fset_window_configuration, compare_window_configurations):
7545 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7547 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7548 that can exceed INT_MAX. Check that EMACS_INT value is in range
7549 before assigning it to the (possibly-narrower) index.
7550 (match_limit): Don't assume that a fixnum can fit in 'int'.
7552 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7555 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7556 (Fvertical_motion): Don't wrap around LINES values that don't fit
7557 in 'int'. Instead, treat them as extreme values. This is good
7558 enough for windows, which can't have more than INT_MAX lines anyway.
7560 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7562 * Require libxml/parser.h to avoid compilation warning.
7564 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7566 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7567 since this reportedly can destroy thread storage.
7569 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7571 * syntax.c (find_defun_start): Update all cache variables if
7572 exiting early (Bug#9401).
7574 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7576 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7578 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7579 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7580 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7582 * term.c (tty_append_glyph): New function.
7583 (produce_stretch_glyph): Static function and its prototype deleted.
7585 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7588 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7590 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7591 when checking :margin (Bug#9390).
7592 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7593 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7594 so that the name doesn't mislead. All uses changed.
7596 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7598 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7601 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7603 * xdisp.c (move_it_to): Don't bail out early when reaching
7604 position beyond to_charpos, if we are scanning backwards.
7605 (move_it_vertically_backward): When DY == 0, make sure we get to
7606 the first character in the line after the newline.
7608 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7610 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7611 (ccl_driver): Do not generate an out-of-range pointer.
7612 (Fccl_execute_on_string): Remove unnecessary check for
7613 integer overflow, noted by Stefan Monnier in
7614 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7615 Remove a FIXME that didn't need fixing.
7616 Simplify the newly-introduced buffer reallocation code.
7618 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7620 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7622 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7624 Integer and memory overflow issues (Bug#9196).
7626 * doc.c (get_doc_string): Rework so that
7627 get_doc_string_buffer_size is the actual buffer size, rather than
7628 being 1 less than the actual buffer size; this makes xpalloc more
7631 * image.c (x_allocate_bitmap_record, cache_image):
7632 * xselect.c (Fx_register_dnd_atom):
7633 Simplify previous changes by using xpalloc.
7635 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7636 since either will do and ptrdiff_t is convenient with xpalloc.
7638 * charset.c (charset_table_size)
7639 (struct charset_sort_data.priority): Now ptrdiff_t.
7640 (charset_compare): Don't overflow if priorities differ greatly.
7641 (Fsort_charsets): Don't assume list length fits in int.
7642 Check for size-calculation overflow when allocating sort data.
7643 (syms_of_charset): Allocate an initial charset table that is
7644 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7646 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7648 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7649 The actual value is always <= INT_MAX, and leaving it unsigned made
7650 overflow checking harder.
7652 * dispextern.h (struct glyph_matrix.rows_allocated)
7653 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7654 with xpalloc. The values are still always <= INT_MAX.
7656 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7658 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7659 (SAFE_NALLOCA): New macro.
7661 * region-cache.c (struct boundary.pos, find_cache_boundary)
7662 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7663 (set_cache_region, invalidate_region_cache)
7664 (revalidate_region_cache, know_region_cache, region_cache_forward)
7665 (region_cache_backward, pp_cache):
7666 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7667 so that ptrdiff_t * can be passed to xpalloc.
7668 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7669 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7670 (pp_cache): Don't assume cache_len fits in int.
7671 * region-cache.h: Adjust extern decls to match.
7673 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7674 EMACS_INT, since either will do, for xpalloc.
7676 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7677 (xnmalloc, xnrealloc, xpalloc): New functions.
7679 * bidi.c (bidi_shelve_header_size): New constant.
7680 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7681 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7683 * bidi.c (bidi_cache_shrink):
7684 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7686 Don't update size of array until after memory allocation succeeds,
7687 because xmalloc/xrealloc may not return.
7688 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7689 now that we have proper integer overflow checking.
7690 (record_overlay_string, overlay_strings): Catch overflows when
7691 calculating size of overlay_str_buf.
7693 * callproc.c (Fcall_process): Check for size overflow when
7694 calculating size of args2.
7695 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7696 Normally we prefer signed values, but sticking with ptrdiff_t would
7697 require adding more-complicated checks.
7699 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7700 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7701 Redo buffer-overflow calculations to avoid integer overflow.
7702 Add a FIXME comment where memory seems to be over-allocated.
7704 * character.c (Fstring): Check for size-calculation overflow.
7706 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7707 unnecessary integer overflow. Check for size overflow.
7708 (encode_coding_object): Don't update size until xmalloc succeeds.
7710 * composite.c (get_composition_id): Check for overflow in glyph
7711 length calculations.
7713 Integer and memory overflow fixes for display code.
7714 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7715 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7716 (scrolling_window): Check for overflow in size calculations.
7717 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7718 Don't assume glyph table len fits in int.
7719 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7720 (row_table_size): Now ptrdiff_t, not int.
7721 (scrolling_window): Avoid overflow in size calculations.
7722 Don't update size until allocation succeeds.
7723 * fns.c (concat): Check for overflow in size calculations.
7724 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
7725 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7726 (NEXT_ALMOST_PRIME_LIMIT): New constant.
7728 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7729 (get_doc_string): Check for size calculation overflow.
7730 Don't update size until allocation succeeds.
7731 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7732 EMACS_INT, where ptrdiff_t will do.
7733 (Fsubstitute_command_keys): Check for string overflow.
7735 * editfns.c (set_time_zone_rule): Don't assume environment length
7737 (message_length): Now ptrdiff_t, not int.
7738 (Fmessage_box): Don't update size until allocation succeeds.
7739 Don't assume message length fits in int.
7740 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7742 * emacs.c (main): Do not reallocate argv, since there is a null at
7743 the end that can be overwritten, and this way there's no need to

7874 (X_LONG_MIN): New macros.
7875 Use them to make the following changes clearer.
7876 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

7878 future maintainers not to raise the value too much later.
7879 (SELECTION_QUANTUM): Remove, replacing with ...
7880 (selection_quantum): ... new function, which avoids overflow.
7882 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

7902 Don't double-block input; malloc is safe here. Don't assume 2**34
7903 - 4 fits in unsigned long. Add an xassert to check
7904 XGetWindowProperty overflow. Be more careful about overflow
7905 calculations, and distinguish size from memory overflow better.

7911 in the range -65535 through -1 fit in an X unsigned short.
7912 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7913 result parameters unless successful. Rely on cons_to_unsigned
7914 to report problems with elements; the old code wasn't right anyway.
7915 (x_check_property_data): Check for int overflow; we cannot use
7916 a wider type due to X limits.
7917 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7949 * lisp.h (hash_lookup, hash_put):
7950 * minibuf.c (Ftest_completion):
7951 Use ptrdiff_t for hash table indexes, not int (which is too
7952 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

7986 (x_send_scroll_bar_event): Likewise. Check that the size does not
7987 exceed limits imposed by XClientMessageEvent, as well as the usual
7988 ptrdiff_t and size_t limits.
7990 * keyboard.c: Overflow, signedness and related fixes.
7991 (make_lispy_movement): Use same integer type in forward decl
7992 that is used in the definition.
7993 (read_key_sequence, keyremap_step):
7994 Change bufsize argument back to int, undoing my 2011-03-30 change.
7995 We prefer signed types, and int is wide enough here.
7996 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7997 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7998 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7999 length, not size_t. Use ptrdiff_t for index, not int.
8000 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8001 possibility of integer overflow.

8029 Prefer int to unsigned where either will do.
8030 (tiff_handler): New function, combining the cores of the
8031 old tiff_error_handler and tiff_warning_handler.
8032 This function is rewritten to use vsnprintf and thereby avoid
8033 stack buffer overflows. It uses only the features of vsnprintf
8034 that are common to both POSIX and native Microsoft.
8035 (tiff_error_handler, tiff_warning_handler): Use it.
8036 (tiff_load, gif_load, imagemagick_load_image):
8037 Don't assume :index value fits in 'int'.
8038 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

8040 the integer types that MagickCropImage accepts. Don't assume
8041 Vimagemagick_render_type has a nonnegative value. Don't assume
8042 size_t fits in 'long'.
8043 (gs_load): Use printmax_t to print the widest integers possible.

8061 accurately, and prefer exact match for point under bidi.
8062 Don't advance `row' beyond the last row of the window.
8064 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8065 into disp_prop; all users changed.

8083 positioning on the newline at EOL of R2L text within L2R
8084 paragraph, and vice versa.
8085 (try_cursor_movement): Check continued rows, in addition to
8086 continuation rows. Fixes unwarranted scroll when point enters a
8087 continued line of R2L text within an L2R paragraph, or vice versa.
8088 (cursor_row_p): Consider the case of point being equal to
8089 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8090 from the end of a short line to the beginning of a continued line

8118 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8119 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8120 candidate is selected by the mouse, and that candidate has a
8121 composed character under the mouse.
8123 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8124 coordinates reported by pos-visible-in-window-p for a composed

8135 composed buffer positions.
8137 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8139 * image.c (gif_load): Don't assume that each subimage has the same
8140 dimensions as the base image. Handle disposal method that is
8141 "undefined" by the gif spec (Bug#9335).
8143 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8145 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8150 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8151 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8152 from an Org mode buffer to a Speedbar frame.
8154 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8155 a composition, take its buffer position from IT->cmp_it.charpos.
8156 Fixes cursor positioning at the beginning of a line that begins
8157 with a composed character.
8159 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8161 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8162 character bidirectional type, use STRONG_L instead. Fixes crashes
8163 in a buffer produced by `describe-categories'.
8165 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8166 members before the level stack, so they would be saved and
8167 restored when copying iterator state. Fixes incorrect reordering
8168 around TABs covered by display properties.
8170 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8203 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8205 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8207 [CYGWIN] (special_realloc): New function.
8208 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8209 requests to realloc storage in the static heap.
8211 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8213 * bidi.c (bidi_initialize): Remove unused local.
8215 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8218 * biditype.h: Remove file.
8219 * makefile.w32-in ($(BLD)/bidi.$(O)):
8220 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8222 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8224 * chartab.c: Improve commentary for the uniprop_table API.
8226 * bidi.c (bidi_paragraph_init): Support zero value of
8227 bidi_ignore_explicit_marks_for_paragraph_level.
8228 (bidi_initialize): Use uniprop_table instead of including
8229 biditype.h and bidimirror.h.
8231 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8232 coordinates of the iterator when restoring from ppos_it.
8235 2011-08-14 Kenichi Handa <handa@m17n.org>
8237 * process.c (create_process): Call setup_process_coding_systems
8238 after the pid of the process is set to -1 (Bug#8162).
8240 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8242 * xdisp.c (move_it_in_display_line_to): Don't invoke
8243 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8244 ppos_it. Fixes vertical cursor motion when line beginning is
8245 covered by an image. (Bug#9296)
8247 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8249 * nsterm.h (ns_run_ascript): Declare.
8250 (NSAPP_DATA2_RUNASSCRIPT): Define.
8252 * nsfns.m (as_script, as_result, as_status): New static variables.
8253 (ns_run_ascript): New function.
8254 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8255 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8256 the event loop. Get status from as_status (Bug#7276).
8258 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8259 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8260 the event loop (Bug#7276).
8262 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8264 * gnutls.c (QCgnutls_bootprop_priority)
8265 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8266 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8267 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8268 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8269 (QCgnutls_bootprop_verify_hostname_error)
8270 (QCgnutls_bootprop_callbacks_verify): Rename from
8271 Qgnutls_bootprop_..., all uses changed.
8273 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8276 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8278 * xfaces.c (Qframe_set_background_mode): Now static.
8279 * dispextern.h (Qframe_set_background_mode): Remove decl.
8281 * process.c (Fnetwork_interface_info): Declare local only if needed.
8283 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8285 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8286 (Fnetwork_interface_list): Allocate in increments of bytes instead
8287 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8288 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8290 (struct ifflag_def): notrailers is smart on OSX.
8291 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8292 Get hardware address with getifaddrs if available.
8294 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8296 * xdisp.c (iterate_out_of_display_property): xassert that
8297 IT->position is set to within IT->object's boundaries. Break from
8298 the loop as soon as EOB is reached; avoids infloops in redisplay
8299 when IT->position is set up wrongly due to some bug.
8300 Set IT->current to match the bidi iterator unconditionally.
8301 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8302 entry. Force push_it to save on the stack the current
8303 buffer/string position, to be restored by pop_it. Fix flags in
8304 the iterator structure wrt the object coming from a display
8305 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8306 properties. (Bug#9284)
8308 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8310 * fontset.c (fontset_get_font_group): Add proper type checks.
8313 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

8316 and LC_VERSION_MIN_MACOSX.
8317 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8318 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8320 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8322 * xdisp.c (forward_to_next_line_start): Allow to use the
8323 no-display-properties-and-no-overlays under bidi display.
8324 Set disp_pos in the bidi iterator to avoid searches for display
8325 properties and overlays.
8327 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8329 * editfns.c (Fset_time_zone_rule): Document relationship with the
8332 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8333 the font entity extracted from the cache (Bug#8109).
8335 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8337 * composite.c (autocmp_chars): Don't reset point. That is done by
8338 restore_point_unwind (Bug#5984).
8340 2011-08-07 Juri Linkov <juri@jurta.org>
8342 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8343 to show the arg `TIME' instead of `TIMEVAL'.
8345 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8347 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8348 display property strides EOL and includes a newline, as in
8349 longlines-mode. (Bug#9254)
8350 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8351 word-wrap under bidirectional display. (Bug#9224)
8353 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8354 is non-zero, even if the data buffer is NULL. Fixes a crash in
8355 vertical-motion with longlines-mode. (Bug#9254)
8357 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8359 * bidi.c <bidi_cache_total_alloc>: Now static.
8360 (bidi_initialize): Initialize bidi_cache_total_alloc.
8362 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8365 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8366 amount allocated this far in `bidi_cache_total_alloc'.
8367 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8368 non-zero, only free the data buffer without restoring the cache
8369 contents. All callers changed.
8371 * dispextern.h (bidi_unshelve_cache): Update prototype.
8373 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8374 (move_it_in_display_line, move_it_to)
8375 (move_it_vertically_backward, move_it_by_lines): Replace the call
8376 to xfree to an equivalent call to bidi_unshelve_cache.
8377 (move_it_in_display_line_to): Fix logic of returning
8378 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8380 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8382 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8383 came from a string character with a `cursor' property. (Bug#9229)
8385 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8387 * Makefile.in (LIB_PTHREAD): New variable.
8388 (LIBES): Add LIB_PTHREAD (Bug#9216).
8390 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8391 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8393 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8395 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8397 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8399 * xterm.c (x_find_topmost_parent): New function.
8400 (x_set_frame_alpha): Find topmost parent window with
8401 x_find_topmost_parent and set the property there also (bug#9181).
8402 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8404 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8406 * callproc.c (Fcall_process): Avoid vfork clobbering
8407 the local vars buffer, coding_systems, current_dir.
8409 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8411 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8413 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8415 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8416 so that it is not optimized away.
8418 * xdisp.c (compute_display_string_pos): Remove unused local.
8420 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8422 Fix slow cursor motion and scrolling in large buffers with
8423 selective display, like Org Mode buffers. (Bug#9218)
8425 * dispextern.h (struct bidi_it): New member disp_prop_p.
8427 * xdisp.c: Remove one-slot cache of display string positions.
8428 (compute_display_string_pos): Accept an additional argument
8429 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8430 for a display string or property. If found, set DISP_PROP_P
8433 * bidi.c (bidi_fetch_char): Accept an additional argument
8434 DISP_PROP_P, and pass it to compute_display_string_pos.
8435 Only handle text covered by a display string if DISP_PROP_P is returned
8436 non-zero. All callers of bidi_fetch_char changed.
8438 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8440 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8442 2010-12-03 Don March <don@ohspite.net>
8444 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8445 last character M-[char] is translated to ESC [char] (bug#7541).
8447 2011-08-02 Kenichi Handa <handa@m17n.org>
8449 * lisp.h (uniprop_table): Extern it.
8451 * chartab.c (uniprop_table): Make it non-static.
8453 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8455 * xdisp.c (forward_to_next_line_start): Accept additional argument
8456 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8458 (reseat_at_next_visible_line_start): Use the bidi iterator state
8459 returned by forward_to_next_line_start to restore the state of
8460 it->bidi_it after backing up to previous newline. (Bug#9212)
8462 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8464 * regex.c (re_comp): Protoize.
8465 (re_exec): Fix return type.
8466 (regexec): Fix type of `ret'. (Bug#9203)
8468 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8470 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8471 This is needed if max-image-size is a floating-point number.
8473 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8475 * print.c (print_object): Print empty symbol as ##.
8477 * lread.c (read1): Read ## as empty symbol.
8479 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8481 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8482 setting frame foreground color (Bug#9175).
8483 (x_set_background_color): Likewise.
8485 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8486 contents (Bug#9176).
8487 (EmacsTooltip -init): Remove bezels and add shadows to
8490 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8491 or scroll bar (Bug#8470).
8493 * nsfont.m (nsfont_open): Remove assignment to voffset and
8494 unnecessary vars hshink, expand, hd, full_height, min_height.
8495 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8497 * nsterm.h (nsfont_info): Remove voffset field.
8499 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8501 Implement strike-through and overline on NextStep (Bug#8863).
8503 * nsfont.m (nsfont_open): Use underline position provided by font,
8504 instead of hard-coded value of 2.
8505 (nsfont_draw): Call ns_draw_text_decoration instead.
8507 * nsterm.h: Add declaration for ns_draw_text_decoration.
8509 * nsterm.m (ns_draw_text_decoration): New function for drawing
8510 underline, overline, and strike-through.
8511 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8512 ns_draw_text_decoration. Change treatment of cursor drawing to
8513 accommodate underlining, etc.
8515 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8517 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8520 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8522 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8523 Without this fix, if a signal arrives just after memory fills up,
8524 'malloc' might be invoked reentrantly.
8526 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8527 In other words, assume that every image size is allowed, on non-X
8528 hosts. This assumption is probably wrong, but it lets Emacs compile.
8530 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8532 * regex.c (re_iswctype): Convert return values to boolean.
8534 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8536 * xdisp.c (compute_display_string_pos): Don't use cached display
8537 string position if the buffer had its restriction changed.
8540 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8542 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8544 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8546 Integer signedness and overflow and related fixes. (Bug#9079)
8548 * bidi.c: Integer size and overflow fixes.
8549 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8550 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8551 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8552 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8553 (bidi_find_other_level_edge):
8554 Use ptrdiff_t instead of EMACS_INT where either will do.
8555 This works better on 32-bit hosts configured --with-wide-int.
8556 (bidi_cache_ensure_space): Check for size-calculation overflow.
8557 Use % rather than repeated addition, for better worst-case speed.
8558 Don't set bidi_cache_size until after xrealloc returns, because it
8560 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8561 (bidi_cache_ensure_space): Also check that the bidi cache size
8562 does not exceed that of the largest Lisp string or buffer. See Eli
8563 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8565 * alloc.c (__malloc_size_t): Remove.
8566 All uses replaced by size_t. See Andreas Schwab's note
8567 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8569 * image.c: Improve checking for integer overflow.
8570 (check_image_size): Assume that f is nonnull, since
8571 it is always nonnull in practice. This is one less thing to
8572 worry about when checking for integer overflow later.
8573 (x_check_image_size): New function, which checks for integer
8574 overflow issues inside X.
8575 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8576 This removes the need for a memory_full check.
8577 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8578 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8579 (xbm_read_bitmap_data): Change locals back to 'int', since
8580 their values must fit in 'int'.
8581 (xpm_load_image, png_load, tiff_load):
8582 Invoke x_create_x_image_and_pixmap earlier,
8583 to avoid much needless work if the image is too large.
8584 (tiff_load): Treat overly large images as if
8585 x_create_x_image_and_pixmap failed, not as malloc failures.
8586 (gs_load): Use x_check_image_size.
8588 * gtkutil.c: Omit integer casts.
8589 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8590 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8592 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8594 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8595 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8596 would wrongly return t on a 64-bit host.
8598 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8599 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8600 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8601 and therefore cause GCC to emit a bogus diagnostic in some cases.
8603 * image.c: Integer signedness and overflow and related fixes.
8604 This is not an exhaustive set of fixes, but it's time to
8605 record what I've got.
8606 (lookup_pixel_color, check_image_size): Remove redundant decls.
8607 (check_image_size): Don't assume that arbitrary EMACS_INT values
8608 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8609 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8610 (tiff_load, imagemagick_load_image):
8611 Check for overflow in size calculations.
8612 (x_create_x_image_and_pixmap): Remove unnecessary test for
8613 xmalloc returning NULL; that can't happen.
8614 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8615 (xpm_color_bucket): Use better integer hashing function.
8616 (xpm_cache_color): Don't possibly over-allocate memory.
8617 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8618 (gif_memory_source):
8619 Use ptrdiff_t, not int or size_t, to record sizes.
8620 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8621 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8622 either works, as we prefer signed integers.
8623 (tiff_read_from_memory, tiff_write_from_memory):
8624 Return tsize_t, not size_t, since that's what the TIFF API wants.
8625 (tiff_read_from_memory): Don't fail simply because the read would
8626 go past EOF; instead, return a short read.
8627 (tiff_load): Omit no-longer-needed casts.
8628 (Fimagemagick_types): Don't assume size fits into 'int'.
8630 Improve hashing quality when configured --with-wide-int.
8631 * fns.c (hash_string): New function, taken from sxhash_string.
8632 Do not discard information about ASCII character case; this
8633 discarding is no longer needed.
8634 (sxhash-string): Use it. Change sig to match it. Caller changed.
8635 * lisp.h: Declare it.
8636 * lread.c (hash_string): Remove, since we now use fns.c's version.
8637 The fns.c version returns a wider integer if --with-wide-int is
8638 specified, so this should help the quality of the hashing a bit.
8640 * emacs.c: Integer overflow minor fix.
8641 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8642 Define only if GNU_LINUX.
8643 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8645 * dispnew.c: Integer signedness and overflow fixes.
8646 Remove unnecessary forward decls, that were a maintenance hassle.
8647 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8649 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8650 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8651 (prepare_desired_row, line_draw_cost):
8652 Use int, not unsigned, where either works.
8653 (save_current_matrix, restore_current_matrix):
8654 Use ptrdiff_t, not size_t, where either works.
8655 (init_display): Check for overflow more accurately, and without
8656 relying on undefined behavior.
8658 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8659 Remove, replacing with the new symbols in lisp.h. All uses changed.
8660 * fileio.c (make_temp_name):
8661 * filelock.c (lock_file_1, lock_file):
8662 * xdisp.c (message_dolog):
8663 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8664 Use pMd etc. instead.
8665 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8666 replacing the pWIDE etc. symbols removed from editfns.c.
8668 * keyboard.h (num_input_events): Now uintmax_t.
8669 This is (very slightly) less likely to mess up due to wraparound.
8672 * buffer.c: Integer signedness fixes.
8673 (alloc_buffer_text, enlarge_buffer_text):
8674 Use ptrdiff_t rather than size_t when either will do, as we prefer
8677 * alloc.c: Integer signedness and overflow fixes.
8678 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8679 (__malloc_size_t): Default to size_t, not to int.
8680 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8681 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8682 Prefer ptrdiff_t to size_t when either would do, as we prefer
8684 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8685 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8686 Now const. Initialize with values that are in range even if char
8688 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8689 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8690 These functions do the right thing with sizes > 2**32.
8691 (check_depth): Now ptrdiff_t, not int.
8692 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8693 Adjust to new way of storing sizes. Check for size overflow bugs
8695 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8696 slightly wrong anyway, as it missed one instance of
8697 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8698 (refill_memory_reserve): Omit needless cast to size_t.
8699 (mark_object_loop_halt): Mark as externally visible.
8701 * xselect.c: Integer signedness and overflow fixes.
8702 (Fx_register_dnd_atom, x_handle_dnd_message):
8703 Use ptrdiff_t, not size_t, since we prefer signed.
8704 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8705 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8706 x_dnd_atoms_size and x_dnd_atoms_length.
8708 * doprnt.c: Prefer signed to unsigned when either works.
8710 * doprnt.c (doprnt):
8712 * xdisp.c (vmessage):
8713 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8714 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8715 prefer signed arithmetic to avoid comparison confusion.
8716 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8717 but is a bit tricky.
8719 Assume freestanding C89 headers, string.h, stdlib.h.
8720 * data.c, doprnt.c, floatfns.c, print.c:
8721 Include float.h unconditionally.
8722 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8723 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8724 * regex.c: Likewise for stddef.h, string.h.
8725 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8726 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8727 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8728 (STDC_HEADERS): Remove obsolete defines.
8729 * sysdep.c: Include limits.h unconditionally.
8731 Assume support for memcmp, memcpy, memmove, memset.
8732 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8733 * regex.c (memcmp, memcpy):
8734 Remove; we assume C89 now.
8736 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8737 (__malloc_safe_bcopy): Remove; no longer needed.
8739 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8740 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8741 well either way, and we prefer signed to unsigned.
8743 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8745 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8746 closes the connection while we're reading (bug#9182).
8748 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8750 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8751 are specified (Bug#9168).
8753 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8755 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8756 Found by GCC static checking and --with-wide-int on a 32-bit host.
8758 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8760 * xdisp.c (compute_display_string_pos): Fix logic of caching
8761 previous display string position. Initialize cached_prev_pos to
8762 -1. Fixes slow-down at the beginning of a buffer.
8764 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8766 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8767 for attrs[LFACE_FONTSET_INDEX].
8769 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8771 * xml.c (parse_region): Remove unused local
8772 that was recently introduced.
8774 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8776 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8777 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8779 * xdisp.c (move_it_in_display_line_to): Record the best matching
8780 position for TO_CHARPOS while scanning the line, and restore it on
8781 exit if none of the characters scanned was an exact match.
8782 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8783 when exact match is impossible due to invisible text, and the
8784 lines are truncated.
8786 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8788 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8791 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8793 Fix a significant slow-down of cursor motion with C-n, C-p,
8794 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8795 auto-repeat under bidi redisplay in fontified buffers.
8796 * xdisp.c (compute_stop_pos_backwards): New function.
8797 (next_element_from_buffer): Call compute_stop_pos_backwards to
8798 find a suitable prev_stop when we find ourselves before
8800 (reseat): Don't look for prev_stop, as that could mean a very long
8802 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8803 <cached_disp_overlay_modiff>: Cache for last found display string
8805 (compute_display_string_pos): Return the cached position if asked
8806 about the same buffer in the same area of character positions, and
8807 the buffer wasn't changed since the time the display string
8808 position was cached.
8810 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8812 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8813 is an integer, which is important for empty lines. (Bug#9149)
8815 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8817 * frame.c (Fmodify_frame_parameters): In tty case, update the
8818 default face if necessary (Bug#4238).
8820 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8822 * editfns.c (Fstring_to_char): No need to explain what a character
8823 is in the docstring (Bug#6576).
8825 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8827 * xml.c (parse_region): Make sure we always return a tree.
8829 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8831 * xml.c (parse_region): If a document contains only comments,
8834 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8836 * xml.c (make_dom): Return comments, too.
8838 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8841 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8842 and the surrounding thread.
8843 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8844 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8845 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8847 * s/openbsd.h (BROKEN_SIGIO): Define.
8848 * unexelf.c (unexec) [__OpenBSD__]:
8849 Don't update the .mdebug section of the Alpha COFF symbol table.
8851 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8853 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8856 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8858 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8859 This fixes some race conditions on the permissions of any newly
8862 * alloc.c (valid_pointer_p): Use pipe, not open.
8863 This fixes some permissions issues when debugging.
8865 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8866 If fchown fails to set both uid and gid, try to set just gid,
8867 as that is sometimes allowed. Adjust the file's mode to eliminate
8868 setuid or setgid bits that are inappropriate if fchown fails.
8870 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8872 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8873 to compare Lisp_Objects.
8874 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8875 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8876 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8878 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8880 * lread.c (read_integer): Unread even EOF character.
8881 (read1): Likewise. Properly record start position of symbol.
8883 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8884 symbol character follows.
8886 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8888 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8889 This works around a problem with the previous change to Fcopy_file.
8890 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8891 and without this change, GCC might complain about discarding
8892 fchown's return value.
8894 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8896 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8898 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8900 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8902 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8904 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8905 it's used from the C level.
8907 * process.c: Use the same condition for POLL_FOR_INPUT in both
8908 keyboard.c and process.c (bug#1858).
8910 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8912 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8913 (Fgnutls_boot): Use it.
8915 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8917 * doc.c (Fsubstitute_command_keys): Revert last change.
8919 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8921 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8922 quotes the next character, and doesn't affect other longer
8923 sequences (bug#8935).
8925 * lread.c (syms_of_lread): Clarify that is isn't only
8926 `eval-buffer' and `eval-defun' that's affected by
8927 `lexical-binding' (bug#8460).
8929 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8931 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8932 bidi redisplay when a line includes both an image and is truncated.
8934 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8936 Fix minor problems found by static checking.
8937 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8938 (elsz): Now a signed constant, not a size_t var. We prefer signed
8939 types to unsigned, to avoid integer comparison confusion. Without
8940 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8941 "cannot optimize loop, the loop counter may overflow", a symptom
8943 * indent.c (Fvertical_motion): Mark locals as initialized.
8944 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8946 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8948 * search.c (Fre_search_backward): Mention `case-fold-search' in
8949 all the re_search_* functions (bug#8138).
8951 * keyboard.c (Fopen_dribble_file): Document when the file is
8954 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8956 * bidi.c (bidi_dump_cached_states): Fix format of displaying

8961 (compute_display_string_end): Accept additional argument STRING.
8962 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8963 (reseat_to_string): Initialize bidi_it->string.s and
8964 bidi_it->string.schars.
8965 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8966 NULL (avoids a crash in bidi_paragraph_init).
8967 Initialize itb.string.lstring.
8968 (init_iterator): Call bidi_init_it only of a valid
8969 buffer position was specified. Initialize paragraph_embedding to
8971 (reseat_to_string): Initialize the bidi iterator.
8972 (display_string): If we need to ignore text properties of
8973 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8974 original value of -1 will not work with bidi.)
8975 (compute_display_string_pos): First arg is now struct
8976 `text_pos *'; all callers changed. Support display properties on
8978 (compute_display_string_end): Support display properties on Lisp
8980 (init_iterator, reseat_1, reseat_to_string): Initialize the
8981 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8982 when iterating on a string not from display properties).
8983 (compute_display_string_pos, compute_display_string_end):
8984 Fix calculation of the object to scan. Fixes an error when using
8986 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8987 base_level_stop; instead, set base_level_stop to BEGV.
8988 Fixes crashes in vertical-motion.
8989 (next_element_from_buffer): Improve commentary for when
8990 the iterator is before prev_stop.
8991 (init_iterator): Initialize bidi_p from the default value of
8992 bidi-display-reordering, not from buffer-local value. Use the
8993 buffer-local value only if initializing for buffer iteration.
8994 (handle_invisible_prop): Support invisible properties on strings
8995 that are being bidi-reordered.
8996 (set_iterator_to_next): Support bidi reordering of C strings and
8998 (next_element_from_string): Support bidi reordering of Lisp
9000 (handle_stop_backwards): Support Lisp strings as well.
9001 (display_string): Support display of R2L glyph rows.
9002 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9003 (init_iterator): Don't initialize it->bidi_p for strings
9005 (reseat_to_string): Initialize it->bidi_p for strings here.
9006 (next_element_from_string, next_element_from_c_string)
9007 (next_element_from_buffer): Add xassert's for correspondence
9008 between IT's object being iterated and it->bidi_it.string
9010 (face_before_or_after_it_pos): Support bidi iteration.

9012 character that is not the first one in the visual order.
9013 (get_visually_first_element): New function, refactored from common
9014 parts of next_element_from_buffer, next_element_from_string, and
9015 next_element_from_c_string.
9016 (tool_bar_lines_needed, redisplay_tool_bar)
9017 (display_menu_bar): Force left-to-right direction. Add a FIXME
9018 comment for making that be controlled by a user option.
9019 (push_it, pop_it): Save and restore the state of the
9020 bidi iterator. Save and restore the bidi_p flag.
9021 (pop_it): Iterate out of display property for string iteration as
9023 (iterate_out_of_display_property): Support iteration over strings.
9024 (handle_single_display_spec): Set up it->bidi_it for iteration
9025 over a display string, and call bidi_init_it.

9028 iterator for displaying display or overlay strings.
9029 (forward_to_next_line_start): Don't use the shortcut if
9031 (back_to_previous_visible_line_start): If handle_display_prop
9032 pushed the iterator stack, restore the internal state of the bidi
9033 iterator by calling bidi_pop_it same number of times.
9034 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9035 and we are bidi-iterating, don't decrement the iterator position;
9036 instead, set the first_elt flag in the bidi iterator, to produce
9038 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9039 (push_display_prop): xassert that we are iterating a buffer.
9040 (push_it, pop_it): Save and restore paragraph_embedding member.
9041 (handle_single_display_spec, next_overlay_string)
9042 (get_overlay_strings_1, reseat_1, reseat_to_string)
9043 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9044 correctly. Don't assume unibyte strings are not bidi-reordered.
9045 (compute_display_string_pos)
9046 (compute_display_string_end): Fix handling the case of C string.
9047 (push_it, pop_it): Save and restore from_disp_prop_p.
9048 (handle_single_display_spec, push_display_prop): Set the
9049 from_disp_prop_p flag.
9050 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9052 popping after iteration over a string that came from a display
9053 property. Fix a typo in popping stretch info. Add an assertion
9054 for verifying that the iterator position is in sync with the bidi
9056 (handle_single_display_spec, get_overlay_strings_1)
9057 (push_display_prop): Fix initialization of paragraph direction for
9058 string when that of the parent object is not yet determined.
9059 (reseat_1): Call bidi_init_it to resync the bidi
9060 iterator with IT's position. (Bug#7616)
9061 (find_row_edges): If ROW->start.pos gives position
9062 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

9070 (try_scrolling, redisplay_window, display_line): Use them when
9071 saving a temporary copy of the iterator and restoring it back.
9072 (back_to_previous_visible_line_start, reseat_1)
9073 (init_iterator): Empty the bidi cache "stack".
9074 (move_it_in_display_line_to): If iterator ended up at
9075 EOL, but we never saw any buffer positions smaller than
9076 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9077 motion in bidi-reordered lines.
9078 (move_it_in_display_line_to): Record prev_method and prev_pos
9079 immediately before the call to set_iterator_to_next. Fixes cursor
9080 motion in bidi-reordered lines with stretch glyphs and strings
9081 displayed in margins. (Bug#8133) (Bug#8867)
9082 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9084 (pos_visible_p): Support positions in bidi-reordered lines.
9085 Save and restore bidi cache.
9087 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9088 (bidi_paragraph_info): Delete unused struct.
9089 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9090 (bidi_cache_start): New variable.

9096 (bidi_level_of_next_char, bidi_find_other_level_edge)
9097 (bidi_move_to_visually_next): Compare cache index with
9098 bidi_cache_start rather than with zero.
9099 (bidi_fetch_char): Accept new argument STRING; all callers
9100 changed. Support iteration over a string. Support strings with
9101 display properties. Support unibyte strings. Fix the type of
9102 `len' according to what STRING_CHAR_AND_LENGTH expects.
9103 (bidi_paragraph_init, bidi_resolve_explicit_1)
9104 (bidi_resolve_explicit, bidi_resolve_weak)

9110 changed to -1 and -2, respectively.
9111 (bidi_char_at_pos): New function.
9112 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
9113 Call it instead of FETCH_MULTIBYTE_CHAR.
9114 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
9115 initialized to valid values.
9116 (bidi_init_it): Don't initialize charpos and bytepos with invalid
9118 (bidi_level_of_next_char): Allow the sentinel "position" to pass
9119 the test for valid cached positions. Fix the logic for looking up

9468 (clone_per_buffer_values): Don't assume that

9509 Random fixes. E.g., (random) never returned negative values.
9510 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9511 subseconds part to the entropy, as that's a bit more random.
9512 Prefer signed to unsigned, since the signedness doesn't matter and
9513 in general we prefer signed. When given a limit, use a
9514 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9515 latter isn't right if USE_2_TAGS_FOR_INTS.
9516 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9517 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9530 This is more efficient than Ffile_directory_p and avoids a minor race.
9532 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9534 * buffer.c (Foverlay_put): Say what the return value is
9537 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9541 error be more correct.
9543 * fns.c (Frequire): Remove the mention of the .gz files, since
9544 that's installation-specific, but keep the mention of

9560 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9662 * eval.c (struct backtrace): Simplify and port the data structure.
9663 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9664 signed bit field, as this assumption is not portable and it makes
9665 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9666 "char debug_on_exit : 1" as this is not portable either; instead,
9667 use the portable "unsigned int debug_on_exit : 1". Remove unused
9668 member evalargs. Remove obsolete comments about cc bombing out.

9838 Don't set size unless allocation succeeds.
9840 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9841 for sizes. Check for string overflow more accurately.

9876 (read_escape): Check for hex character overflow.
9878 2011-06-22 Leo Liu <sdl.web@gmail.com>
9880 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9881 Move to minibuffer.el.
9883 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9885 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9886 The following patches are for when GLYPH_DEBUG && !XASSERT.

9900 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9902 (debug_method_add): Use va_list and vsprintf rather than relying
9903 on undefined behavior with wrong number of arguments.
9904 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9905 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9906 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9907 since we're not interested in debugging glyphs with old libraries.
9908 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9909 GCC 4.6.0's static checking.
9911 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

9950 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9951 (x_session_initialize): Do not assume string length fits in int.
9953 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9954 This is unlikely, but can occur if DPI is outlandish.
9956 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9957 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

9995 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9996 Reformulate so as not to need the command string.
9997 Invoke gzip -cd rather than gunzip, as it's more portable.
9998 (lock_info_type, lock_file_1, lock_file):
9999 Don't assume pid_t and time_t fit in unsigned long.
10000 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10001 (current_lock_owner): Prefer signed type for sizes.
10002 Use memcpy, not strncpy, where memcpy is what is really wanted.
10003 Don't assume (via atoi) that time_t and pid_t fit in int.
10004 Check for time_t and/or pid_t out of range, e.g., via a network share.
10005 Don't alloca where an auto var works fine.
10007 * fileio.c: Fix some integer overflow issues.
10008 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10009 Don't assume string length fits in int.
10010 (directory_file_name): Don't assume string length fits in long.

10035 All uses changed. This doesn't fix a bug, but it simplifies the
10036 code away from its former Hollerith-constant appearance, and it's
10037 one less 'int' to worry about when looking at integer-overflow issues.
10038 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10040 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10041 This didn't break anything, but it didn't help either.
10042 It's confusing to put a bogus integer in a place where the actual
10043 value does not matter.
10044 (LIST_END_P): Remove unused macro and its bogus comment.
10045 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10047 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10048 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10050 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10051 We prefer signed types, and the value cannot exceed the EMACS_INT
10052 range anyway (because otherwise the length would not be representable).
10053 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10054 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10055 This avoids a GCC warning when WIDE_EMACS_INT.
10057 * indent.c (sane_tab_width): New function.
10058 (current_column, scan_for_column, Findent_to, position_indentation)
10059 (compute_motion): Use it. This is just for clarity.
10060 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10062 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10064 * lisp.h (lint_assume): New macro.
10065 * composite.c (composition_gstring_put_cache):
10066 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10068 * editfns.c, insdel.c:
10069 Omit unnecessary forward decls, to simplify future changes.
10071 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10073 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10075 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10076 Use much-faster test for byte-length change.
10077 Don't assume string byte-length fits in 'int'.
10078 Check that character arg fits in 'int'.
10079 (mapcar1): Declare byte as byte, for clarity.
10081 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10083 * fns.c (concat): Catch string overflow earlier.
10084 Do not rely on integer wraparound.
10086 * dispextern.h (struct it.overlay_strings_charpos)
10087 (struct it.selective): Now EMACS_INT, not int.
10088 * xdisp.c (forward_to_next_line_start)
10089 (back_to_previous_visible_line_start)
10090 (reseat_at_next_visible_line_start, next_element_from_buffer):
10091 Don't arbitrarily truncate the value of 'selective' to int.
10093 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10095 * composite.c: Don't truncate sizes to 'int'.
10096 (composition_gstring_p, composition_reseat_it)
10097 (composition_adjust_point): Use EMACS_INT, not int.
10098 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10099 not EMACS_UINT, for indexes.
10101 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10103 * buffer.c: Include <verify.h>.
10104 (struct sortvec.priority, struct sortstr.priority):
10105 Now EMACS_INT, not int.
10106 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10107 (struct sortstr.size, record_overlay_string)
10108 (struct sortstrlist.size, struct sortlist.used):
10109 Don't truncate size to int.
10110 (record_overlay_string): Check for size-calculation overflow.
10111 (init_buffer_once): Check at compile-time, not run-time.
10113 2011-06-22 Jim Meyering <meyering@redhat.com>
10115 Don't leak an XBM-image-sized buffer
10116 * image.c (xbm_load): Free the image buffer after using it.
10118 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10121 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10122 that Sun C diagnosed.
10123 * fns.c (secure_hash): Fix pointer signedness issue.
10124 * intervals.c (static_offset_intervals): New function.
10125 (offset_intervals): Use it.
10127 2011-06-21 Leo Liu <sdl.web@gmail.com>
10130 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10133 * fns.c (secure_hash): Rename from crypto_hash_function and change
10134 the first arg to accept symbols.
10135 (Fsecure_hash): New primitive.
10136 (syms_of_fns): New symbols.
10138 2011-06-20 Deniz Dogan <deniz@dogan.se>
10140 * process.c (Fset_process_buffer): Clarify return value in
10143 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10145 * dispnew.c (add_window_display_history): Use BVAR.
10147 * xdisp.c (debug_method_add): Use BVAR.
10148 (check_window_end, dump_glyph_matrix, dump_glyph)
10149 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10151 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10154 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10155 check till after the cache is created in init_frame_faces.
10157 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10159 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10161 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10163 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10164 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10165 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10167 Improve buffer-overflow checking (Bug#8873).
10168 * fileio.c (Finsert_file_contents):
10169 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10170 Remove the old (too-loose) buffer overflow checks.
10171 They weren't needed, since make_gap checks for buffer overflow.
10172 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10173 The old code merely checked for Emacs fixnum overflow, and relied
10174 on undefined (wraparound) behavior. The new code avoids undefined
10175 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10177 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10178 Tune. Don't use wider integers than needed. Don't use alloca.
10179 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10181 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10183 * insdel.c, lisp.h (buffer_overflow): New function.
10184 (insert_from_buffer_1, replace_range, replace_range_2):
10185 * insdel.c (make_gap_larger):
10186 * editfns.c (Finsert_char):
10187 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10189 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10191 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10193 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10195 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10196 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10198 * fileio.c: Don't assume EMACS_INT fits in off_t.
10199 (emacs_lseek): New static function.
10200 (Finsert_file_contents, Fwrite_region): Use it.
10201 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10203 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10205 * fns.c: Don't overflow int when computing a list length.
10206 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10207 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10208 truncation on 64-bit hosts. Check for QUIT every
10209 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10210 faster and is responsive enough.
10211 (Flength): Report an error instead of overflowing an integer.
10212 (Fsafe_length): Return a float if the value is not representable
10213 as a fixnum. This shouldn't happen except in contrived situations.
10214 (Fnthcdr, Fsort): Don't assume list length fits in int.
10215 (Fcopy_sequence): Don't assume vector length fits in int.
10217 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10218 (header_size, word_size): New constants.
10219 (allocate_vectorlike): Don't check size overflow here.
10220 (allocate_vector): Check it here instead, since this is the only
10221 caller of allocate_vectorlike that could cause overflow.
10222 Check that the new vector's length is representable as a fixnum.
10224 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10225 The previous code was bogus. For example, next_almost_prime (32)
10226 returned 39, which is undesirable as it is a multiple of 3; and
10227 next_almost_prime (24) returned 25, which is a multiple of 5 so
10228 why was the code bothering to check for multiples of 7?
10230 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10232 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10234 Variadic C functions now count arguments with ptrdiff_t.
10235 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10236 Back then I didn't know that the Emacs coding style prefers signed int.
10237 Also, in the meantime I found a few more instances where arguments
10238 were being counted with int, which may truncate counts on 64-bit
10239 machines, or EMACS_INT, which may be unnecessarily wide.
10240 * lisp.h (struct Lisp_Subr.function.aMANY)
10241 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10242 Arg counts are now ptrdiff_t, not size_t.
10243 All variadic functions and their callers changed accordingly.
10244 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10245 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10246 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10247 * callint.c (Fcall_interactively): Check arg count for overflow,
10248 to avoid potential buffer overrun. Use signed char, not 'int',
10249 for 'varies' array, so that we needn't bother to check its size
10250 calculation for overflow.
10251 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10252 * eval.c (apply_lambda):
10253 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10254 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10255 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10257 * callint.c (Fcall_interactively): Don't use index var as event count.
10259 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10260 * mem-limits.h (SIZE): Remove; no longer used.
10262 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10264 Remove unnecessary casts.
10265 * xterm.c (x_term_init):
10266 * xfns.c (x_set_border_pixel):
10267 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10268 These aren't needed now that we assume ANSI C.
10270 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10271 It's more likely to cause problems (due to unsigned overflow)
10274 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10276 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10278 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10280 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10282 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10284 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10286 GLYPH_CODE_FACE returns EMACS_INT, not int.
10287 * dispextern.h (merge_faces):
10288 * xfaces.c (merge_faces):
10289 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10290 Don't assume EMACS_INT fits in int.
10292 * character.h (CHAR_VALID_P): Remove unused parameter.
10293 * fontset.c, lisp.h, xdisp.c: All uses changed.
10295 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10297 * fns.c (concat): Minor tuning based on overflow analysis.
10298 This doesn't fix any bugs. Use int to hold character, instead
10299 of constantly refetching from Emacs object. Use XFASTINT, not
10300 XINT, for value known to be a character. Don't bother comparing
10301 a single byte to 0400, as it's always less.
10303 * floatfns.c (Fexpt):
10304 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10306 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10309 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10311 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10312 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10313 incorrectly succeed when S was a string, because 4294967386 was
10314 truncated before it was used.
10316 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10317 Otherwise, an out-of-range integer could cause undefined behavior
10320 * composite.c: Use int, not EMACS_INT, for characters.
10321 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10322 EMACS_INT, for values that are known to be in character range.
10323 This doesn't fix any bugs but is the usual style inside Emacs and
10324 may generate better code on 32-bit machines.
10326 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10327 This is for reasons similar to the recent CHAR_STRING fix.
10328 * charset.c (Fencode_char): Check that character arg is actually
10329 a character. Pass an int to ENCODE_CHAR.
10330 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10331 wider than 'int', as a compile-time check to prevent future regressions
10334 * character.c (char_string): Remove unnecessary casts.
10336 Make sure a 64-bit char is never passed to CHAR_STRING.
10337 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10338 by silently ignoring the top 32 bits, allowing some values
10339 that were far too large to be valid characters.
10340 * character.h: Include <verify.h>.
10341 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10342 arguments are no wider than unsigned, as a compile-time check
10343 to prevent future regressions in this area.
10345 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10346 (Fsubst_char_in_region):
10348 * xdisp.c (decode_mode_spec_coding):
10349 Adjust to CHAR_STRING's new requirement.
10350 * editfns.c (Finsert_char, Fsubst_char_in_region):
10351 * fns.c (concat): Check that character args are actually
10352 characters. Without this test, these functions did the wrong
10353 thing with wildly out-of-range values on 64-bit hosts.
10355 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10356 These casts should not be needed on 32-bit hosts, either.
10357 * keyboard.c (read_char):
10358 * lread.c (Fload): Remove casts to unsigned.
10360 * lisp.h (UNSIGNED_CMP): New macro.
10361 This fixes comparison bugs on 64-bit hosts.
10362 (ASCII_CHAR_P): Use it.
10363 * casefiddle.c (casify_object):
10364 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10365 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10366 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10367 * dispextern.h (FACE_FROM_ID):
10368 * keyboard.c (read_char): Use UNSIGNED_CMP.
10370 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10371 not to EMACS_INT, to avoid GCC warning.
10373 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10375 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10376 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10377 isn't needed on 32-bit machines.
10379 * buffer.c (Fgenerate_new_buffer_name):
10380 Use EMACS_INT for count, not int.
10381 (advance_to_char_boundary): Return EMACS_INT, not int.
10383 * data.c (Qcompiled_function): Now static.
10385 * window.c (window_body_lines): Now static.
10387 * image.c (gif_load): Rename local to avoid shadowing.
10389 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10390 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10391 * alloc.c (make_save_value): Integer argument is now of type
10392 ptrdiff_t, not int.
10393 (mark_object): Use ptrdiff_t, not int.
10394 * lisp.h (pD): New macro.
10395 * print.c (print_object): Use it.
10397 * alloc.c: Use EMACS_INT, not int, to count objects.
10398 (total_conses, total_markers, total_symbols, total_vector_size)
10399 (total_free_conses, total_free_markers, total_free_symbols)
10400 (total_free_floats, total_floats, total_free_intervals)
10401 (total_intervals, total_strings, total_free_strings):
10402 Now EMACS_INT, not int. All uses changed.
10403 (Fgarbage_collect): Compute overall total using a double, so that
10404 integer overflow is less likely to be a problem. Check for overflow
10405 when converting back to an integer.
10406 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10407 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10408 These were 'int' variables that could overflow on 64-bit hosts;
10409 they were never used, so remove them instead of repairing them.
10410 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10411 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10412 Previously, this ceilinged at INT_MAX, but that doesn't work on
10414 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10416 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10417 (allocate_vectorlike): Check for ptrdiff_t overflow.
10418 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10419 when a (possibly-narrower) signed value would do just as well.
10420 We prefer using signed arithmetic, to avoid comparison confusion.
10422 * alloc.c: Catch some string size overflows that we were missing.
10423 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10424 for convenience in STRING_BYTES_MAX.
10425 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10426 The definition here is exact; the one in lisp.h was approximate.
10427 (allocate_string_data): Check for string overflow. This catches
10428 some instances we weren't catching before. Also, it catches
10429 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10430 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10431 and ptrdiff_t and EMACS_INT are both 64 bits.
10433 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10434 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10435 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10437 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10439 * alloc.c (Fmake_string): Check for out-of-range init.
10441 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10443 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10445 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10447 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10448 xg_get_default_scrollbar_width.
10450 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10451 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10452 (style_changed_cb): Call update_theme_scrollbar_width and call
10453 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10454 all frames (Bug#8505).
10455 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10456 Call gtk_window_set_resizable if HAVE_GTK3.
10457 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10458 and height if HAVE_GTK3 (Bug#8505).
10459 (scroll_bar_width_for_theme): New variable.
10460 (update_theme_scrollbar_width): New function.
10461 (xg_get_default_scrollbar_width): Move code to
10462 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10463 (xg_initialize): Call update_theme_scrollbar_width.
10465 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10467 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10469 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10471 * frame.c (make_frame): Call other_buffer_safely instead of
10474 * window.c (temp_output_buffer_show): Call display_buffer with
10475 second argument Vtemp_buffer_show_specifiers and reset latter
10476 immediately after the call.
10477 (Vtemp_buffer_show_specifiers): New variable.
10478 (auto_window_vscroll_p, next_screen_context_lines)

10927 (Fframe_root_window, Fframe_first_window)
10928 (Fframe_selected_window): Move here from frame.c. Accept frame
10929 or arbitrary window as argument. Update doc-strings.
10930 (Fminibuffer_window): Move up in code.
10931 (Fwindow_minibuffer_p): Move up in code and simplify.
10932 (Fset_frame_selected_window): Move here from frame.c.
10934 (Fselected_window, select_window, Fselect_window): Move up in
10935 code. Minor doc-string fixes.
10937 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
10939 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
10940 Do not assume that spare memory exists; that assumption is valid
10941 only if SYSTEM_MALLOC.
10942 (LARGE_REQUEST): New macro, so that the issue of large requests
10943 is separated from the issue of spare memory.
10945 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
10947 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

10973 New error handlers.
10974 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
10975 Obey Vx_select_enable_clipboard_manager. Catch errors in
10976 x_clipboard_manager_save (Bug#8779).
10977 (Vx_select_enable_clipboard_manager): New variable.
10978 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
10980 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
10982 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
10984 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10986 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
10987 in the current matrix if keep_current_p is non-zero.

10991 * bidi.c (bidi_level_of_next_char): Fix last change.
10993 2011-06-03 Eli Zaretskii <eliz@gnu.org>
10995 Support bidi reordering of text covered by display properties.
10997 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
10998 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
10999 (bidi_cache_search, bidi_cache_iterator_state)
11000 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11001 (bidi_level_of_next_char, bidi_move_to_visually_next):
11002 Support character positions inside a run of characters covered by a
11004 (bidi_paragraph_init, bidi_resolve_explicit_1)
11005 (bidi_level_of_next_char): Call bidi_fetch_char and
11006 bidi_fetch_char_advance instead of FETCH_CHAR and
11007 FETCH_CHAR_ADVANCE.

11009 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11011 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11012 instead of using explicit *_CHAR codes.
11013 (bidi_resolve_explicit, bidi_resolve_weak):
11014 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11015 bidirectional text is supported only in multibyte buffers.
11016 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11017 it to initialize the frame_window_p member of struct bidi_it.
11018 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11019 (bidi_resolve_explicit, bidi_resolve_weak)

11021 bidi_it->nchars is non-positive.
11022 (bidi_level_of_next_char): Don't try to lookup the cache for the
11023 next/previous character if nothing is cached there yet, or if we
11024 were just reseat()'ed to a new position.
11026 * xdisp.c (set_cursor_from_row): Set start and stop points
11027 according to the row's direction when priming the loop that looks
11028 for the glyph on which to display cursor.
11029 (single_display_spec_intangible_p): Function deleted.
11030 (display_prop_intangible_p): Reimplement to call
11031 handle_display_spec instead of single_display_spec_intangible_p.
11032 Accept 3 additional arguments needed by handle_display_spec.
11033 This fixes incorrect cursor motion across display property with complex
11034 values: lists, `(when COND...)' forms, etc.
11035 (single_display_spec_string_p): Support property values that are
11036 lists with the argument STRING its top-level element.
11037 (display_prop_string_p): Fix the condition for processing a
11038 property that is a list to be consistent with handle_display_spec.
11039 (handle_display_spec): New function, refactored from the
11040 last portion of handle_display_prop.
11041 (compute_display_string_pos): Accept additional argument
11042 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11043 value of a `display' property is a "replacing spec".
11044 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11045 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11046 the display property, but just return a value indicating whether
11047 the display property will replace the characters it covers.
11048 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11049 frame_window_p members of struct bidi_it.
11050 (compute_display_string_pos, compute_display_string_end):
11052 (push_it): Accept second argument POSITION, where pop_it should
11053 jump to continue iteration.
11054 (reseat_1): Initialize bidi_it.disp_pos.
11056 * keyboard.c (adjust_point_for_property): Adjust the call to
11057 display_prop_intangible_p to its new signature.
11059 * dispextern.h (struct bidi_it): New member frame_window_p.
11060 (bidi_init_it): Update prototypes.
11061 (display_prop_intangible_p): Update prototype.
11062 (compute_display_string_pos, compute_display_string_end):
11063 Declare prototypes.
11064 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11067 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11069 Malloc failure behavior now depends on size of allocation.
11070 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11071 * lisp.h: Change signatures accordingly.
11072 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11073 All callers changed. (Bug#8762)
11075 * gnutls.c: Use Emacs's memory allocators.
11076 Without this change, the gnutls library would invoke malloc etc.
11077 directly, which causes problems on non-SYNC_INPUT hosts, and which
11078 runs afoul of improving memory_full behavior. (Bug#8761)
11079 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11080 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11081 xfree instead of the default malloc, realloc, free.
11082 (Fgnutls_boot): No need to check for memory allocation failure,
11083 since xmalloc does that for us.
11085 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11086 * category.c (hash_get_category_set):
11087 * ccl.c (ccl_driver):
11088 * charset.c (Fdefine_charset_internal):
11089 * charset.h (struct charset.hash_index):

11091 (composition_gstring_put_cache):
11092 * composite.h (struct composition.hash_index):
11093 * dispextern.h (struct image.hash):
11094 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11095 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11096 (hashfn_equal, hashfn_user_defined, make_hash_table)
11097 (maybe_resize_hash_table, hash_lookup, hash_put)
11098 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11099 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11100 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11101 * image.c (make_image, search_image_cache, lookup_image)
11102 (xpm_put_color_table_h):
11103 * lisp.h (struct Lisp_Hash_Table):
11104 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11105 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11106 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11107 * alloc.c (allocate_vectorlike):
11108 Check for overflow in vector size calculations.
11109 * ccl.c (ccl_driver):
11110 Check for overflow when converting EMACS_INT to int.
11111 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11112 need to be updated by these changes.
11113 * fns.c (make_hash_table, maybe_resize_hash_table):
11114 Check for integer overflow with large hash tables.
11115 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11116 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11117 (SXHASH_REDUCE): New macro.
11118 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11119 Use it instead of discarding useful hash info with large hash values.
11120 (sxhash_float): New function.
11121 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11122 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11123 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11124 Rewrite to use FIXNUM_BITS, as this simplifies things.
11125 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11126 Adjust signatures to match updated version of code.
11127 (consing_since_gc): Now EMACS_INT, since a single hash table can
11128 use more than INT_MAX bytes.
11130 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11132 Make it possible to build with GCC-4.6+ -O2 -flto.
11134 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11136 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11138 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11139 Call minibuffer-inactive-mode.
11141 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11143 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11144 Update dependencies.
11146 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11148 * data.c (init_data): Remove code for UTS, this system is not
11151 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11153 Don't force ./temacs to start in terminal mode.
11155 * frame.c (make_initial_frame): Initialize faces in all cases, not
11156 only when CANNOT_DUMP is defined.
11157 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11159 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11161 * dispnew.c (add_window_display_history): Use const for the string
11162 pointer. Remove declaration, not needed.
11164 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11166 Use 'inline', not 'INLINE'.
11167 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11168 * alloc.c, fontset.c (INLINE): Remove.
11169 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11170 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11171 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11172 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11173 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11175 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11177 Make it possible to run ./temacs.
11179 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11180 syms_of_callproc does the same thing. Remove test for
11181 "initialized", do it in the caller.
11182 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11184 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11186 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11187 (read_minibuf): Use get_minibuffer.
11188 (syms_of_minibuf): Use DEFSYM.
11189 (Qmetadata): New var.
11190 * data.c (Qbuffer): Don't make it static.
11191 (syms_of_data): Use DEFSYM.
11193 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11195 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11196 (CCL_CODE_MIN): New macro.
11198 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11200 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11202 * eval.c (Qdebug): Now static.
11203 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11204 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11205 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11207 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11209 * image.c: Various fixes to ImageMagick code comments.
11210 (Fimagemagick_types): Doc fix.
11212 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11214 Minor fixes prompted by GCC 4.6.0 warnings.
11216 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11218 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11219 (x_clipboard_manager_save_all): Move extern decl to ...
11220 * xterm.h: ... here, so that it can be checked for consistency.
11222 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11224 * xselect.c (x_clipboard_manager_save_frame)
11225 (x_clipboard_manager_save_all): New functions.
11226 (Fx_clipboard_manager_save): Lisp function deleted.
11228 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11229 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11231 * xterm.h: Update prototype.
11233 2011-05-28 William Xu <william.xwl@gmail.com>
11235 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11236 exiting (Bug#8239).
11238 2011-05-28 Jim Meyering <meyering@redhat.com>
11240 Avoid a sign-extension bug in crypto_hash_function.
11241 * fns.c (to_uchar): Define.
11242 (crypto_hash_function): Use it to convert some newly-signed
11243 variables to unsigned, to avoid sign-extension bugs. For example,
11244 without this change, (md5 "truc") would evaluate to
11245 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11246 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11247 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11249 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11251 Integer overflow fixes.
11253 * dbusbind.c: Serial number integer overflow fixes.
11254 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11255 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11256 to hold a serial number that is too large for a fixnum.
11257 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11258 Check for serial numbers out of range. Decode any serial number
11259 that was so large that it became a float. (Bug#8722)
11261 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11262 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11263 Use XFASTINT rather than XUINT when numbers are nonnegative.
11264 (xd_append_arg, Fdbus_method_return_internal):
11265 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11266 arguments, check that Lisp number is nonnegative, rather than
11267 silently wrapping negative numbers around. (Bug#8722)
11268 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11271 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11273 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11275 ccl: Add integer overflow checks.
11276 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11277 (IN_INT_RANGE): New macros.
11278 (ccl_driver): Use them to check for integer overflow when
11279 decoding a CCL program. Many of the new checks are whether XINT (x)
11280 fits in int; it doesn't always, on 64-bit hosts. The new version
11281 doesn't catch all possible integer overflows, but it's an
11282 improvement. (Bug#8719)
11284 * alloc.c (make_event_array): Use XINT, not XUINT.
11285 There's no need for unsigned here.
11287 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11288 This follows up to the 2011-05-06 change that substituted uintptr_t
11289 for EMACS_INT. This case wasn't caught back then.
11291 Rework Fformat to avoid integer overflow issues.
11292 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11293 now (part of C89). Include <verify.h>.
11294 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11295 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11296 (Fformat): Avoid the prepass trying to compute sizes; it was only
11297 approximate and thus did not catch overflow reliably. Instead, walk
11298 through the format just once, formatting and computing sizes as we go,
11299 checking for integer overflow at every step, and allocating a larger
11300 buffer as needed. Keep track separately whether the format is
11301 multibyte. Keep only the most-recently calculated precision, rather
11302 than them all. Record whether each argument has been converted to
11303 string. Use EMACS_INT, not int, for byte and char and arg counts.
11304 Support field widths and precisions larger than INT_MAX. Avoid
11305 sprintf's undefined behavior with conversion specifications such as %#d
11306 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11307 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11308 formatting out-of-range floating point numbers with int
11309 formats. (Bug#8668)
11311 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11313 * data.c: Avoid integer truncation in expressions involving floats.
11314 * data.c: Include <intprops.h>.
11315 (arith_driver): When there's an integer overflow in an expression
11316 involving floating point, convert the integers to floating point
11317 so that the resulting value does not suffer from catastrophic
11318 integer truncation. For example, on a 64-bit host (* 4
11319 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11320 Do not rely on undefined behavior after integer overflow.
11322 merge count_size_as_multibyte, parse_str_to_multibyte
11323 * character.c, character.h (count_size_as_multibyte):
11324 Rename from parse_str_to_multibyte; all uses changed.
11325 Check for integer overflow.
11326 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11327 since it's now a duplicate of the other. This is more of
11328 a character than a buffer op, so better that it's in character.c.
11329 * fns.c, print.c: Adjust to above changes.
11331 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11333 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11335 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11337 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11338 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11339 (x_clipboard_manager_save): Now static.
11340 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11342 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11343 (crypto_hash_function): Now static.
11344 Fix pointer signedness problems. Avoid unnecessary initializations.
11346 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11348 * termhooks.h (Vselection_alist): Make it terminal-local.
11350 * terminal.c (create_terminal): Initialize it.
11352 * xselect.c: Support for clipboard managers.
11353 (Vselection_alist): Move to termhooks.h as terminal-local var.
11354 (LOCAL_SELECTION): New macro.
11355 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11356 (symbol_to_x_atom): Remove gratuitous arg.
11357 (x_handle_selection_request, lisp_data_to_selection_data)
11358 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11359 (x_own_selection, x_get_local_selection, x_convert_selection):
11360 New arg, specifying work frame. Use terminal-local Vselection_alist.
11361 (some_frame_on_display): Delete unused function.
11362 (Fx_own_selection_internal, Fx_get_selection_internal)
11363 (Fx_disown_selection_internal, Fx_selection_owner_p)
11364 (Fx_selection_exists_p): New optional frame arg.
11365 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11366 (x_handle_selection_clear): Don't treat other terminals with the
11367 same keyboard specially. Use the terminal-local Vselection_alist.
11368 (x_clear_frame_selections): Use Frun_hook_with_args.
11370 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11372 * xterm.h: Add support for those atoms.
11374 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11376 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11377 (converted_selections, conversion_fail_tag): New global variables.
11378 (x_selection_request_lisp_error): Free the above.
11379 (x_get_local_selection): Remove unnecessary code.
11380 (x_reply_selection_request): Args changed; handle arbitrary array
11381 of converted selections stored in converted_selections.
11382 Separate the XChangeProperty and SelectionNotify steps.
11383 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11384 (x_convert_selection): New function.
11385 (x_handle_selection_event): Simplify.
11386 (x_get_foreign_selection): Don't ignore incoming requests while
11387 waiting for an answer; this will fail when we implement
11388 SAVE_TARGETS, and seems unnecessary anyway.
11389 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11390 (Vx_sent_selection_functions): Doc fix.
11392 2011-05-26 Leo Liu <sdl.web@gmail.com>
11394 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11396 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11398 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11400 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11401 for fringe update if it has periodic bitmap.
11402 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11403 and fringe_bitmap_periodic_p.
11405 * fringe.c (get_fringe_bitmap_data): New function.
11406 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11407 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11408 row. Mark glyph row for fringe update if periodicity changed.
11410 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11411 for fringe update unless it has periodic bitmap.
11413 2011-05-25 Kenichi Handa <handa@m17n.org>
11415 * xdisp.c (get_next_display_element): Set correct it->face_id for
11416 a static composition.
11418 2011-05-24 Leo Liu <sdl.web@gmail.com>
11421 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11423 * fns.c (crypto_hash_function, Fsha1): New function.
11424 (Fmd5): Use crypto_hash_function.
11425 (syms_of_fns): Add Ssha1.
11427 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11429 * gnutls.c: Remove unused macros.
11430 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11431 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11432 Remove macros that are defined and never used.
11433 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11435 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11437 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11438 (Fx_get_selection_internal): Minor cleanup.
11439 (Fx_own_selection_internal): Rename arguments for consistency with
11442 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11444 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11446 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11448 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11450 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11452 * dispnew.c (scrolling_window): Don't exclude the case that the
11453 last enabled row in the desired matrix touches the bottom boundary.
11455 2011-05-21 Glenn Morris <rgm@gnu.org>
11457 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11458 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11459 and add some more files.
11461 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11463 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11464 report_file_error introduced by the change from 2011-05-07.
11466 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11468 * systime.h (Time): Define only if emacs is defined.
11469 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11470 where the include path doesn't have X11/X.h by default. See
11471 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11473 2011-05-20 Kenichi Handa <handa@m17n.org>
11475 * composite.c (find_automatic_composition): Fix previous change.
11477 2011-05-20 Glenn Morris <rgm@gnu.org>
11479 * lisp.mk: New file, split from Makefile.in.
11480 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11481 (shortlisp): Remove.
11482 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11484 2011-05-19 Glenn Morris <rgm@gnu.org>
11486 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11487 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11488 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11489 (lisp): Set the order to that of loadup.el.
11490 (shortlisp): Make it a copy of $lisp.
11491 (SOME_MACHINE_LISP): Remove.
11492 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11493 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11495 2011-05-18 Kenichi Handa <handa@m17n.org>
11497 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11498 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11499 (find_automatic_composition): Mostly rewrite for efficiency.
11501 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11503 * makefile.w32-in: Update dependencies.
11505 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11507 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11508 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11510 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11512 Fix some integer overflow issues, such as string length overflow.
11514 * insdel.c (count_size_as_multibyte): Check for string overflow.
11516 * character.c (lisp_string_width): Check for string overflow.
11517 Use EMACS_INT, not int, for string indexes and lengths; in
11518 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11519 the resulting string length overflows an EMACS_INT; instead,
11520 report a string overflow if no precision given. When checking for
11521 precision exhaustion, use a check that cannot possibly have
11522 integer overflow. (Bug#8675)
11523 * character.h (lisp_string_width): Adjust to new signature.
11525 * alloc.c (string_overflow): New function.
11526 (Fmake_string): Use it. This doesn't change behavior, but saves
11527 a few bytes and will simplify future changes.
11528 * character.c (string_escape_byte8): Likewise.
11529 * lisp.h (string_overflow): New decl.
11531 Fixups, following up to the user-interface timestamp change.
11532 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11533 for UI timestamps, instead of unsigned long.
11534 * msdos.c (mouse_get_pos): Likewise.
11535 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11536 * w32gui.h (Time): Define by including "systime.h" rather than by
11537 declaring it ourselves. (Bug#8664)
11539 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11540 * image.c (clear_image_cache): Likewise.
11542 * term.c (term_mouse_position): Don't assume time_t wraparound.
11544 Be more systematic about user-interface timestamps.
11545 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11546 and sometimes 'EMACS_UINT', to represent these timestamps.
11547 This change causes it to use 'Time' uniformly, as that's what X uses.
11548 This makes the code easier to follow, and makes it easier to catch
11549 integer overflow bugs such as Bug#8664.
11550 * frame.c (Fmouse_position, Fmouse_pixel_position):
11551 Use Time, not unsigned long, for user-interface timestamps.
11552 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11553 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11554 * keyboard.h (last_event_timestamp): Likewise.
11555 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11556 * menu.h (xmenu_show): Likewise.
11557 * term.c (term_mouse_position): Likewise.
11558 * termhooks.h (struct input_event.timestamp): Likewise.
11559 (struct terminal.mouse_position_hook): Likewise.
11560 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11561 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11562 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11563 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11564 what it was before.
11565 * menu.h, termhooks.h: Include "systime.h", for Time.
11567 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11568 Don't assume that the difference between two unsigned long values
11569 can fit into an integer. At this point, we know button_down_time
11570 <= event->timestamp, so the difference must be nonnegative, so
11571 there's no need to cast the result if double-click-time is
11572 nonnegative, as it should be; check that it's nonnegative, just in
11573 case. This bug is triggered when events are more than 2**31 ms
11574 apart (about 25 days). (Bug#8664)
11576 * xselect.c (last_event_timestamp): Remove duplicate decl.
11577 (x_own_selection): Remove needless cast to unsigned long.
11579 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11580 that always fit in int. Use a sentinel instead of a counter, to
11581 avoid a temp and to allay GCC's concerns about possible int overflow.
11582 * frame.h (struct frame): Use int for menu_bar_items_used
11583 instead of EMACS_INT, since it always fits in int.
11585 * menu.c (grow_menu_items): Check for int overflow.
11587 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11589 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11590 Before, the code was not consistent. These values cannot exceed
11591 2**31 - 1 so there's no need to make them unsigned.
11592 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11593 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11594 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11596 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11598 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11599 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11600 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11601 presumably because the widths might not match.
11603 * window.c (size_window): Avoid needless test at loop start.
11605 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11607 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11609 2011-05-12 Drew Adams <drew.adams@oracle.com>
11611 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11613 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11615 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11616 `width' to `bar_area_x' and `bar_area_width', respectively.
11617 (x_scroll_run): Take account of fringe background extension.
11619 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11620 Rename local vars `left' and `width' to `bar_area_x' and
11621 `bar_area_width', respectively.
11622 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11623 background extension.
11625 2011-05-10 Jim Meyering <meyering@redhat.com>
11627 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11629 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11631 * image.c (Finit_image_library): Return t for built-in image types,
11632 like pbm and xbm. (Bug#8640)
11634 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11636 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11638 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11640 * w32console.c (Fset_screen_color): Doc fix.
11641 (Fget_screen_color): New function.
11642 (syms_of_ntterm): Defsubr it.
11644 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11645 unlink the temporary file if Fcall_process didn't create it in the
11647 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11648 child process will be redirected to a file specified with `:file'.
11649 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11650 cue to call_process_cleanup not to close that handle.
11652 2011-05-07 Ben Key <bkey76@gmail.com>
11654 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11655 one of two shell specific rules, either bootstrap-temacs-CMD or
11656 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11657 to the previous implementation of the bootstrap-temacs rule.
11658 The bootstrap-temacs-CMD rule is similar to the previous
11659 implementation of the bootstrap-temacs rule except that it
11660 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11663 These changes, along with some changes to nt/configure.bat,
11664 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11665 earlier fix to add support for --cflags and --ldflags options
11666 that include quotes so that it works whether make uses cmd or
11669 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11671 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11672 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11674 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11675 a string. Handle both cases.
11676 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11677 (Fdbus_register_method): Use Qinvalid_function.
11679 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11681 * makefile.w32-in: Update dependencies.
11682 (LISP_H): Add inttypes.h and stdin.h.
11683 (PROCESS_H): Add unistd.h.
11685 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11687 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11688 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11690 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11692 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11694 * term.c (vfatal): Remove stray call to va_end.
11695 It's not needed and the C Standard doesn't allow it here anyway.
11697 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11698 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11700 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11703 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11705 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11707 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11709 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11711 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11713 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11714 * charset.c (Fdefine_charset_internal): Don't initialize
11715 charset.code_space[15]. The value was garbage, on hosts with
11716 32-bit int (Bug#8600).
11718 * lread.c (read_integer): Be more consistent with string-to-number.
11719 Use string_to_number to do the actual conversion; this avoids
11720 rounding errors and fixes some other screwups. Without this fix,
11721 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11722 (digit_to_number): Move earlier, for benefit of read_integer.
11723 Return -1 if the digit is out of range for the base, -2 if it is
11724 not a digit in any supported base. (Bug#8602)
11726 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11728 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11729 to match comment at start of function. This also removes a
11730 GCC warning about overflow in a 32+64-bit port.
11732 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11734 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11735 Reported by Stefan Monnier in
11736 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11737 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11738 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11740 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11741 (EMACS_UINTPTR): Likewise, with uintptr_t.
11743 * lisp.h: Prefer 64-bit EMACS_INT if available.
11744 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11745 on 32-bit hosts that have 64-bit int, so that they can access
11747 However, temporarily disable this change unless the temporary
11748 symbol WIDE_EMACS_INT is defined.
11750 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11752 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11753 This removes an assumption that EMACS_INT and long are the same
11754 width as pointers. The assumption is true for Emacs porting targets
11755 now, but we want to make other targets possible.
11756 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11757 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11758 In the rest of the code, change types of integers that hold casted
11759 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11760 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11761 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11762 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11763 No need to cast type when ORing.
11764 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11765 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11766 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11767 assume EMACS_INT is the same width as char *.
11768 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11769 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11770 Remove no-longer-needed casts.
11771 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11772 (xg_tool_bar_help_callback, xg_make_tool_item):
11773 Use EMACS_INTPTR to hold an integer
11774 that will be cast to void *; this can avoid a GCC warning
11775 if EMACS_INT is not the same width as void *.
11776 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11777 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11778 (current_message_1, set_message_1):
11779 Use a local to convert to proper width without a cast.
11780 * xmenu.c (dialog_selection_callback): Likewise.
11782 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11783 Also, don't assume VALBITS / RAND_BITS is less than 5,
11784 and don't rely on undefined behavior when shifting a 1 left into
11786 * lisp.h (get_random): Change signature to match.
11788 * lread.c (hash_string): Use size_t, not int, for hash computation.
11789 Normally we prefer signed values; but hashing is special, because
11790 it's better to use unsigned division on hash table sizes so that
11791 the remainder is nonnegative. Also, size_t is the natural width
11792 for hashing into memory. The previous code used 'int', which doesn't
11793 retain enough info to hash well into very large tables.
11794 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11796 * dbusbind.c: Don't possibly lose pointer info when converting.
11797 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11798 Use XPNTR rather than XHASH, so that the high-order bits of
11799 the pointer aren't lost when converting through void *.
11801 * eval.c (Fautoload): Don't double-shift a pointer.
11803 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

11837 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11838 Remove unused parameter `fildes'.
11839 * process.c (read_process_output, send_process): Don't pass it.
11841 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11843 Fix previous change: the library cache is defined in w32.c.
11844 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11845 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

11886 * process.c: Include lisp.h before w32.h, not after.
11887 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11888 instead of gnutls_record_check_pending.
11890 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11892 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11894 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11895 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11898 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11900 * xterm.c (x_set_frame_alpha): Do not set property on anything

11935 (Fcall_process_region): Ditto.
11937 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11939 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11940 rather than `XVECTOR (FOO)->size'.
11942 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11943 inttypes.h, as a gnulib replacement is used if it not available in
11946 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11948 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11949 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11950 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11952 * coding.c (coding_alloc_by_realloc): Error out if destination
11953 will grow beyond MOST_POSITIVE_FIXNUM.
11954 (decode_coding_emacs_mule): Abort if there isn't enough place in
11955 charbuf for the composition carryover bytes. Reserve an extra

11971 produced by %s or %c overflows available buffer space. (Bug#8545)
11973 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11975 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12010 Improve `doprnt' and its usage. (Bug#8545)
12011 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12012 `format_end'. Remove support for %l as a conversion specifier.
12013 Don't use xrealloc. Improve diagnostics when the %l size modifier
12014 is used. Update the commentary.
12016 * eval.c (verror): Simplify calculation of size_t.
12018 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12021 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12023 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12026 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12028 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12029 This makes this file independent of the recent pseudovector change.
12031 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12033 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12035 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12036 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12037 Remove unused local.
12038 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12040 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12041 GCC 4.6.0 optimizes based on type-based alias analysis.
12042 For example, if b is of type struct buffer * and v of type struct
12043 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12044 != &v->size, and therefore "v->size = 1; b->size = 2; return
12045 v->size;" must therefore return 1. This assumption is incorrect
12046 for Emacs, since it type-puns struct Lisp_Vector * with many other
12047 types. To fix this problem, this patch adds a new type struct
12048 vectorlike_header that documents the constraints on layout of vectors
12049 and pseudovectors, and helps optimizing compilers not get fooled
12050 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12051 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12052 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12054 (XSETPVECTYPE): Rewrite in terms of new macro.
12055 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12056 This is a bit clearer, and further avoids the possibility of
12057 undesirable aliasing.
12058 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12059 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12060 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12061 since Lisp_Subr is a special case (no "next" field).
12062 (ASIZE): Now uses header.size rather than size.
12063 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12064 to avoid the hassle of writing XVECTOR (foo)->header.size.
12065 (struct vectorlike_header): New type.
12066 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12067 object, to help avoid aliasing.
12068 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12069 (SUBRP): Likewise, since Lisp_Subr is a special case.
12070 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12071 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12072 (struct Lisp_Hash_Table): Combine first two members into a single
12073 struct vectorlike_header member. All uses of "size" and "next" members
12074 changed to be "header.size" and "header.next".
12075 * buffer.h (struct buffer): Likewise.
12076 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12077 * frame.h (struct frame): Likewise.
12078 * process.h (struct Lisp_Process): Likewise.
12079 * termhooks.h (struct terminal): Likewise.
12080 * window.c (struct save_window_data, struct saved_window): Likewise.
12081 * window.h (struct window): Likewise.
12082 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12083 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12084 * buffer.c (init_buffer_once): Likewise.
12085 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12087 * process.c (Fformat_network_address): Use local var for size,
12090 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12092 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12093 * data.c (atof): Remove decl; no longer used or needed.
12094 (digit_to_number): Move to lread.c.
12095 (Fstring_to_number): Use new string_to_number function, to be
12096 consistent with how the Lisp reader treats infinities and NaNs.
12097 Do not assume that floating-point numbers represent EMACS_INT
12098 without losing information; this is not true on most 64-bit hosts.
12099 Avoid double-rounding errors, by insisting on integers when
12100 parsing non-base-10 numbers, as the documentation specifies.
12101 * lisp.h (string_to_number): New decl, replacing ...
12102 (isfloat_string): Remove.
12103 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12104 (read1): Do not accept +. and -. as integers; this
12105 appears to have been a coding error. Similarly, do not accept
12106 strings like +-1e0 as floating point numbers. Do not report
12107 overflow for integer overflows unless the base is not 10 which
12108 means we have no simple and reliable way to continue.
12109 Break out the floating-point parsing into a new
12110 function string_to_number, so that Fstring_to_number parses
12111 floating point numbers consistently with the Lisp reader.
12112 (digit_to_number): Move here from data.c. Make it static inline.
12113 (E_CHAR, EXP_INT): Remove, replacing with ...
12114 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12115 (string_to_number): New function, replacing isfloat_string.
12116 This function checks for valid syntax and produces the resulting
12117 Lisp float number too. Rework it so that string-to-number
12118 no longer mishandles examples like "1.0e+". Use strtoumax,
12119 so that overflow for non-base-10 numbers is reported only when
12120 there's no portable and simple way to convert to floating point.
12122 * textprop.c (set_text_properties_1): Rewrite for clarity,
12123 and to avoid GCC warning about integer overflow.
12125 * intervals.h (struct interval): Use EMACS_INT for members
12126 where EMACS_UINT might cause problems. See
12127 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12128 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12129 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12131 (offset_intervals): Tell GCC not to worry about length overflow
12132 when negating a negative length.
12134 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12135 (overrun_check_free): Likewise.
12137 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12138 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12141 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12142 (gnutls_make_error): Rename local to avoid shadowing.
12143 (gnutls_emacs_global_deinit): ifdef out; not used.
12144 (Fgnutls_boot): Use const for pointer to readonly storage.
12145 Comment out unused local. Fix pointer signedness problems.
12147 * lread.c (openp): Don't stuff size_t into an 'int'.
12148 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12149 about possible signed overflow.
12151 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12152 (GDK_KEY_g): Don't define if already defined.
12153 (xg_prepare_tooltip): Avoid pointer signedness problem.
12154 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12156 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12157 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12159 * xfns.c (Fx_window_property): Simplify a bit,
12160 to make a bit faster and to avoid GCC 4.6.0 warning.
12161 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12163 * fns.c (internal_equal): Don't assume size_t fits in int.
12165 * alloc.c (compact_small_strings): Tighten assertion a little.
12167 Replace pEd with more-general pI, and fix some printf arg casts.
12168 * lisp.h (pI): New macro, generalizing old pEd macro to other
12169 conversion specifiers. For example, use "...%"pI"d..." rather
12170 than "...%"pEd"...".
12171 (pEd): Remove. All uses replaced with similar uses of pI.
12172 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12173 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12174 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12175 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12176 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12177 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12178 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12180 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12181 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12182 * print.c (safe_debug_print, print_object): Likewise.
12183 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12185 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12186 avoiding the 0 flag, which is not portable.
12187 * process.c (Fmake_network_process): Use pI to avoid cast.
12188 * region-cache.c (pp_cache): Likewise.
12189 * xdisp.c (decode_mode_spec): Likewise.
12190 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12191 behavior on 64-bit hosts with printf arg.
12192 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12193 (x_stop_queuing_selection_requests): Likewise.
12194 (x_get_window_property): Don't truncate byte count to an 'int'
12197 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12198 here, since it parses constructs like leading '-' and spaces,
12199 which are not wanted; and it overflows with large numbers.
12200 Instead, simply match F[0-9]+, which is what is wanted anyway.
12202 * alloc.c: Remove unportable assumptions about struct layout.

12206 plus offsetof, to remove unportable assumptions about struct layout.
12207 These assumptions hold on all porting targets that I know of, but
12208 they are not guaranteed, they're easy to remove, and removing them
12209 makes further changes easier.
12211 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12212 This doesn't fix a bug but makes the code clearer.
12213 (string_overrun_cookie): Now const. Use initializers that

12215 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12216 can cause Emacs to crash when string overrun checking is enabled.
12217 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12218 multiple of sizeof (EMACS_INT); it need not be, if
12219 alignof(EMACS_INT) < sizeof (EMACS_INT).

12256 supported by the function. Use SAFE_ALLOCA instead of always
12259 * eval.c (verror): Don't limit the buffer size at size_max-1, that

12387 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12388 to `error' in error message about FINAL_CHAR argument. Make sure
12389 FINAL_CHAR is a character, and use %c when it is passed as
12390 argument to `error'.
12392 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12394 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12396 * w32.c: Include <time.h>.

12460 * dispextern.h (struct redisplay_interface): Rename param
12461 to avoid shadowing.

12580 ns_descriptor_to_entity that were caused by using free to
12581 deallocate memory blocks that were allocated by xmalloc (via
12582 xstrdup). This caused Emacs to crash when compiled with
12583 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12584 --enable-checking=xmallocoverrun). xfree is now used to
12585 deallocate these memory blocks.

12602 (emacs_read, emacs_write): Use it.
12603 * process.c (send_process): Adjust to the new signatures of
12604 emacs_write and emacs_gnutls_write. Do not attempt to store

13090 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13092 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13093 argument, local variables, and return value.
13095 * lisp.h: Update prototypes of emacs_write and emacs_read.
13097 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13099 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13101 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13103 Fix more problems found by GCC 4.6.0's static checks.
13105 * xdisp.c (vmessage): Use a better test for character truncation.
13107 * charset.c (load_charset_map): <, not <=, for optimization,
13108 and to avoid potential problems with integer overflow.
13109 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13110 * casetab.c (set_identity, shuffle): Likewise.
13111 * editfns.c (Fformat): Likewise.
13112 * syntax.c (skip_chars): Likewise.
13114 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13115 This also lets GCC 4.6.0 generate slightly better loop code.
13117 * callint.c (Fcall_interactively): <, not <=, for optimization.
13118 (Fcall_interactively): Count the number of arguments produced,
13119 not the number of arguments given. This is simpler and lets GCC
13120 4.6.0 generate slightly better code.
13122 * ftfont.c: Distingish more carefully between FcChar8 and char.
13123 The previous code passed unsigned char * to a functions like
13124 strlen and xstrcasecmp that expect char *, which does not
13125 conform to the C standard.
13126 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13127 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13128 char * when the C standard requires it.
13130 * keyboard.c (read_char): Remove unused var.
13132 * eval.c: Port to Windows vsnprintf (Bug#8435).
13133 Include <limits.h>.
13134 (SIZE_MAX): Define if the headers do not.
13135 (verror): Do not give up if vsnprintf returns a negative count.
13136 Instead, grow the buffer. This ports to Windows vsnprintf, which
13137 does not conform to C99. Problem reported by Eli Zaretskii.
13138 Also, simplify the allocation scheme, by avoiding the need for
13139 calling realloc, and removing the ALLOCATED variable.
13141 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13143 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13144 But keep the doprint source code for now, as we might revamp it
13145 and use it again (Bug#8435).
13146 * lisp.h (doprnt): Remove.
13147 * Makefile.in (base_obj): Remove doprnt.o.
13148 * deps.mk (doprnt.o): Remove.
13150 error: Print 32- and 64-bit integers portably (Bug#8435).
13151 Without this change, on typical 64-bit hosts error ("...%d...", N)
13152 was used to print both 32- and 64-bit integers N, which relied on
13153 undefined behavior.
13154 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13155 * lisp.h (error, verror): Mark as printf-like functions.
13156 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13157 Report overflow in size calculations when allocating printf buffer.
13158 Do not truncate output string at its first null byte.
13159 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13160 Truncate the output at a character boundary, since vsnprintf does not
13162 * charset.c (check_iso_charset_parameter): Convert internal
13163 character to string before calling 'error', since %c now has the
13165 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13166 overflow when computing char to be passed to 'error'. Do not
13167 pass Lisp_Object to 'error'; pass the integer instead.
13168 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13169 formatted with plain %d.
13171 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13173 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13175 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13177 * xterm.c (x_catch_errors): Remove duplicate declaration.
13179 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13181 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13183 2011-04-10 Jim Meyering <meyering@redhat.com>
13185 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13186 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13187 return ssize_t not "int", and use size_t as the buffer length.
13188 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13189 * gnutls.h: Update declarations.
13190 * process.c (read_process_output): Use ssize_t, to match.
13191 (send_process): Likewise.
13193 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13195 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13197 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13199 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13200 Use unsigned char, to match FcChar8 type definition.
13202 * xterm.c (handle_one_xevent):
13203 * xmenu.c (create_and_show_popup_menu):
13204 * xselect.c (x_decline_selection_request)
13205 (x_reply_selection_request): Avoid type-punned deref of X events.
13207 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13209 Fix some uses of `int' instead of EMACS_INT.
13210 * search.c (string_match_1, fast_string_match)
13211 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13212 (scan_buffer, find_next_newline_no_quit)
13213 (find_before_next_newline, search_command, Freplace_match)
13214 (Fmatch_data): Make some `int' variables be EMACS_INT.
13216 * xdisp.c (display_count_lines): 3rd argument and return value now
13217 EMACS_INT. All callers changed.
13218 (pint2hrstr): Last argument is now EMACS_INT.
13220 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13221 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13222 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13223 (decode_coding_utf_16, decode_coding_emacs_mule)
13224 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13225 (decode_coding_ccl, decode_coding_charset)
13226 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13227 (decode_coding_iso_2022, decode_coding_emacs_mule)
13228 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13229 <char_offset, last_offset>: Declare EMACS_INT.
13230 (encode_coding_utf_8, encode_coding_utf_16)
13231 (encode_coding_emacs_mule, encode_invocation_designation)
13232 (encode_designation_at_bol, encode_coding_iso_2022)
13233 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13234 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13236 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13237 (encode_invocation_designation): Last argument P_NCHARS is now
13239 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13240 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13242 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13245 * ccl.c (Fccl_execute_on_string): Declare some variables
13248 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13250 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13252 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13254 * process.c (Fformat_network_address): Doc fix.
13256 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13258 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13260 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13262 * keyboard.c (read_char): Call Lisp function help-form-show,
13263 instead of using internal_with_output_to_temp_buffer.
13264 (Qhelp_form_show): New var.
13265 (syms_of_keyboard): Use DEFSYM macro.
13267 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13269 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13271 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13273 * process.c (Flist_processes): Remove to Lisp.
13274 (list_processes_1): Delete.

13280 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13282 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13284 Fix more problems found by GCC 4.6.0's static checks.
13286 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13288 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13290 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13292 * xdisp.c (vmessage): Mark as a printf-like function.
13294 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13296 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13298 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13299 printf-like functions.

13301 to system-supplied API.
13303 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13305 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13306 This avoids several warnings with gcc -Wstrict-overflow.
13307 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13308 directly, rather than having caller test rule sign. This avoids
13309 some unnecessary tests.
13310 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13311 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13312 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13314 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13315 (xfont_open): Avoid unnecessary tests.
13317 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13319 * composite.h, composite.c (composition_gstring_put_cache):
13320 Use EMACS_INT, not int, for length.

13323 breaking out part of COMPOSITION_DECODE_RULE.
13324 (COMPOSITION_DECODE_RULE): Use it.

13326 by using the new macro.
13328 * textprop.c (set_text_properties_1): Change while to do-while,
13329 since the condition is always true at first.
13331 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13332 (interval_deletion_adjustment): Return unsigned value.
13335 * process.c (list_processes_1, create_pty, read_process_output):

13347 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13348 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13349 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13351 * print.c (print_error_message): Avoid int overflow.
13353 * font.c (font_list_entities): Redo for clarity,
13354 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13356 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13357 (font_score): Avoid potential overflow in diff calculation.
13359 * fns.c (substring_both): Remove var that is set but not used.
13360 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13362 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13364 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13365 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13366 can always succeed if overflow has undefined behavior.
13368 * search.c (boyer_moore, wordify): Remove vars set but not used.
13369 (wordify): Omit three unnecessary tests.
13371 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13372 All callers changed. This avoids the need for an unused var.
13374 * casefiddle.c (casify_region): Remove var that is set but not used.

13384 Check for integer overflow on size calculations.
13386 * buffer.c (Fprevious_overlay_change): Remove var that is set
13389 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13390 Remove vars that are set but not used.
13391 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13392 (timer_check_2): Mark vars as initialized.
13394 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13396 * image.c (lookup_image): Remove var that is set but not used.
13397 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13399 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13400 that are set but not used.
13402 * xfns.c (make_invisible_cursor): Don't return garbage
13403 if XCreateBitmapFromData fails (Bug#8410).
13405 * xselect.c (x_get_local_selection, x_handle_property_notify):
13406 Remove vars that are set but not used.
13408 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

13418 (map_tty_color) [!defined MSDOS]: Likewise.
13420 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13422 * coding.c: Remove vars that are set but not used.
13423 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13424 All callers changed.
13425 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13426 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13427 (decode_coding_charset): Remove vars that are set but not used.
13429 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13430 that is set but not used.
13432 * print.c (print_object): Remove var that is set but not used.
13434 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13435 The gnulib version avoids calling malloc in the usual case,
13436 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13437 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13438 * filelock.c (current_lock_owner): Likewise.
13439 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

13443 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13444 ../lib/careadlinkat.h.
13446 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13448 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13449 first non-nil return value).

13463 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13464 and thereabouts. All callers changed.
13465 (get_per_char_metric): Remove parameter `f', unused since
13466 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13549 Limit scrolling to 100 screen lines.
13550 (redisplay_window): Even when falling back on "recentering",
13551 position point in the window according to scroll-conservatively,
13552 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13554 (try_scrolling): When point is above the window, allow searching
13555 as far as scroll_max, or one screenful, to compute vertical
13556 distance from PT to the scroll margin position. This prevents
13557 try_scrolling from unnecessarily failing when
13558 scroll-conservatively is set to a value slightly larger than the
13559 window height. Clean up the case of PT below the margin at bottom
13560 of window: scroll_max can no longer be INT_MAX. When aggressive
13561 scrolling is in use, don't let point enter the opposite scroll
13562 margin as result of the scroll.
13563 (syms_of_xdisp) <scroll-conservatively>: Document the
13564 threshold of 100 lines for never-recentering scrolling.
13566 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13568 * dispextern.h (move_it_by_lines):
13569 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13570 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13571 (message_log_check_duplicate): Remove parameters `prev_bol' and
13572 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13573 (redisplay_internal): Remove parameter `preserve_echo_area',
13574 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13576 * indent.c (Fvertical_motion):
13577 * window.c (window_scroll_pixel_based, Frecenter):
13578 Don't pass `need_y_p' to `move_it_by_lines'.
13580 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13582 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13583 steal a few bits to be more compact.
13584 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13585 Remove unneeded casts.
13587 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13589 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13591 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13592 binding" message (bug#7967).
13594 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13596 Fix more problems found by GCC 4.6.0's static checks.
13598 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13599 Remove unused local var.
13601 * editfns.c (Fmessage_box): Remove unused local var.
13603 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13604 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13605 Omit unused local vars.
13606 * window.c (shrink_windows): Omit unused local var.
13607 * menu.c (digest_single_submenu): Omit unused local var.
13608 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13609 Omit unused local var.
13611 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13612 Don't assume string length fits in int.
13613 (keyremap_step, read_key_sequence): Use size_t for sizes.
13614 (read_key_sequence): Don't check last_real_key_start redundantly.
13616 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13617 instead of alloca (Bug#8344).
13619 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13620 (Fbacktrace_frame): Don't assume nframes fits in int.
13622 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13624 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13627 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13629 * cm.c (calccost): Turn while-do into do-while, for clarity.
13631 * keyboard.c (syms_of_keyboard): Use the same style as later
13632 in this function when indexing through an array. This also
13633 works around GCC bug 48267.
13635 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13637 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13639 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13640 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13642 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13643 This avoids undefined behavior on integer overflow, and is a bit
13644 more convenient anyway since it is compared to a size_t variable.
13646 Variadic C functions now count arguments with size_t, not int.
13647 This avoids an unnecessary limitation on 64-bit machines, which
13648 caused (substring ...) to crash on large vectors (Bug#8344).
13649 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13650 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13654 * editfns.c (general_insert_function): Likewise.
13655 * eval.c (struct backtrace.nargs, interactive_p)
13656 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13657 (funcall_lambda, mark_backtrace): Likewise.
13658 * fns.c (concat): Likewise.
13659 * frame.c (x_set_frame_parameters): Likewise.
13660 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13661 0 if not found, not -1. All callers changed.
13663 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13664 (stack_copy_size): Now size_t, not int.
13665 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13667 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13669 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13670 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13671 All callers changed.
13673 * lisp.h (multibyte_char_to_unibyte):
13674 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13675 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13676 * character.h (CHAR_TO_BYTE8):
13677 * cmds.c (internal_self_insert):
13678 * editfns.c (general_insert_function):
13679 * keymap.c (push_key_description):
13680 * search.c (Freplace_match):
13681 * xdisp.c (message_dolog, set_message_1): All callers changed.
13683 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13685 * keyboard.c (safe_run_hook_funcall): New function.
13686 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13687 don't set the hook to nil, but remove the offending function instead.
13688 (Qcommand_hook_internal): Remove, unused.
13689 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13690 Vcommand_hook_internal.
13692 * eval.c (enum run_hooks_condition): Remove.
13693 (funcall_nil, funcall_not): New functions.
13694 (run_hook_with_args): Call each function through a `funcall' argument.
13695 Remove `cond' argument, now redundant.
13696 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13697 (Frun_hook_with_args_until_failure): Adjust accordingly.
13698 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13700 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13702 * dispextern.h (string_buffer_position): Remove declaration.
13704 * print.c (strout): Remove parameter `multibyte', unused since
13705 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13707 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13708 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13709 All callers changed.
13711 * w32.c (_wsa_errlist): Use braces for struct initializers.
13713 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13714 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13715 All callers changed.
13716 (string_buffer_position): Likewise. Also, make static (it's never
13717 used outside xdisp.c).

13721 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13722 All callers changed.
13724 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13726 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13737 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
13739 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

13752 2011-03-26 Eli Zaretskii <eliz@gnu.org>
13754 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
13755 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13757 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13759 * w32.c (read_unc_volume): Use parameter `henum', instead of
13760 global variable `wget_enum_handle'.
13762 * keymap.c (describe_vector): Remove parameters `indices' and
13763 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

13774 * w32menu.c (w32_menu_display_help):
13775 * xmenu.c (show_help_event, menu_help_callback):
13776 Adjust calls to `show_help_echo'.
13778 * gtkutil.c (xg_maybe_add_timer):
13779 * keyboard.c (readable_events):
13780 * process.c (wait_reading_process_output):
13781 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
13783 * insdel.c (adjust_markers_gap_motion):
13784 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

13858 2011-03-23 Julien Danjou <julien@danjou.info>
13860 * term.c (Fsuspend_tty, Fresume_tty):
13861 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13862 * window.c (temp_output_buffer_show):

13869 * callint.c (Fcall_interactively):
13870 * buffer.c (Fkill_all_local_variables):
13871 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13873 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13874 unconditionally since it does the check itself.
13876 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13878 Fix more problems found by GCC 4.5.2's static checks.
13880 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13881 the first time through the loop, since we know p0 < p1 then.
13882 This also avoids a gcc -Wstrict-overflow warning.
13884 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13885 leading to a memory leak, possible in functions like
13886 load_charset_map_from_file that can allocate an unbounded number
13887 of objects (Bug#8318).
13889 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13890 that could (at least in theory) be that large.
13892 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13893 This is less likely to overflow, and avoids undefined behavior if
13894 overflow does occur. All callers changed. Use strtoul to scan
13895 for the unsigned long integer.
13896 (pint2hrstr): Simplify and tune code slightly.
13897 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13899 * scroll.c (do_scrolling): Work around GCC bug 48228.
13900 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13902 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13903 This also avoids a warning with gcc -Wstrict-overflow.

13905 This also avoids a warning with gcc -Wstrict-overflow.
13907 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13910 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13912 * process.c (Fmake_network_process): Use socklen_t, not int,
13913 where POSIX says socklen_t is required in portable programs.
13914 This fixes a porting bug on hosts like 64-bit HP-UX, where
13915 socklen_t is wider than int (Bug#8277).
13916 (Fmake_network_process, server_accept_connection):
13917 (wait_reading_process_output, read_process_output):
13920 * process.c: Rename or move locals to avoid shadowing.
13921 (list_processes_1, Fmake_network_process):
13922 (read_process_output_error_handler, exec_sentinel_error_handler):
13923 Rename or move locals.
13924 (Fmake_network_process): Define label "retry_connect" only if needed.
13925 (Fnetwork_interface_info): Fix pointer signedness.
13926 (process_send_signal): Add cast to avoid pointer signedness problem.
13927 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13928 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13930 Make tparam.h and terminfo.c consistent.
13931 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13932 Include tparam.h instead, since it declares them.
13933 * cm.h (PC): Remove extern decl; tparam.h now does this.
13934 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13935 * terminfo.c: Include tparam.h, to check interfaces.
13936 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13937 (tparam): Adjust signature to match interface in tparam.h;
13938 this removes some undefined behavior. Check that outstring and len
13939 are zero, which they always are with Emacs.
13940 * tparam.h (PC, BC, UP): New extern decls.
13942 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13943 (xftfont_open): Rename locals to avoid shadowing.
13945 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13946 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13947 (OTF_TAG_SYM): Omit macro if not needed.
13948 (ftfont_list): Remove unused local.
13949 (get_adstyle_property, ftfont_pattern_entity):
13950 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13951 Rename locals to avoid shadowing.
13953 * xfont.c (xfont_list_family): Mark var as initialized.
13955 * xml.c (make_dom): Now static.
13957 * composite.c (composition_compute_stop_pos): Rename local to
13959 (composition_reseat_it): Remove unused locals.
13960 (find_automatic_composition, composition_adjust_point): Likewise.
13961 (composition_update_it): Mark var as initialized.
13962 (find_automatic_composition): Mark vars as initialized,
13963 with a FIXME (Bug#8290).
13965 character.h: Rename locals to avoid shadowing.
13966 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13967 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13968 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13969 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13970 to avoid shadowing.
13972 * textprop.c (property_change_between_p): Remove; unused.
13974 * intervals.c (interval_start_pos): Now static.
13976 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13978 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13979 Rename locals to avoid shadowing.
13981 * sound.c (wav_play, au_play, Fplay_sound_internal):
13982 Fix pointer signedness.

13989 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13991 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13992 clobbering (Bug#8298).
13993 * sysdep.c (sys_subshell): Likewise.
13994 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13996 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13997 This should get cleaned up, so that child_setup has the
13998 same signature on all platforms.
14000 * callproc.c (call_process_cleanup): Now static.
14001 (relocate_fd): Rename locals to avoid shadowing.
14003 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

14131 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14132 some of which prompt warnings from gcc -Wbad-function-cast.
14133 (Fformat_time_string, Fencode_time, Finsert_char):
14134 (Ftranslate_region_internal, Fformat):

14162 (Fmemory_limit): Cast sbrk's returned value to char *.
14164 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14167 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14169 Use functions, not macros, for up- and down-casing (Bug#8254).
14170 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14171 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14172 to use the following functions instead of these macros.
14173 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14174 EMACS_INT, since callers assume the returned value fits in int.
14175 (upcase1): Likewise, for UPCASE_TABLE.
14176 (uppercasep, lowercasep, upcase): New static inline functions.
14177 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14187 (regex_compile, re_match_2_internal): Mark locals as initialized.
14188 (RETALLOC_IF): Define only if needed.
14189 (WORDCHAR_P): Likewise. This one is never needed, but is used
14190 only in a comment talking about a compiler bug, so put inside
14191 the #if 0 of that comment.
14192 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14193 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14219 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14220 New macros, so that the caller can use some names other than
14221 gcpro1, gcpro2, etc.
14222 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14224 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14225 argument, for consistency with GCPRO2_VAR, etc: it is now the
14226 prefix of the variable, not the variable itself. All uses
14228 * dired.c (directory_files_internal, file_name_completion):
14229 Rename locals to avoid shadowing.
14231 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14232 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14233 dired.c's scmp function, had undefined behavior.
14234 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14235 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14236 * buffer.h: ... to here, because these macros use current_buffer,
14237 and the new implementation with inline functions needs to have
14238 current_buffer in scope now, rather than later when the macros
14240 (downcase, upcase1): New static inline functions.
14241 (DOWNCASE, UPCASE1): Reimplement using these functions.
14242 This avoids undefined behavior in expressions like
14243 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14244 from race conditions in accessing the global variables
14245 case_temp1 and case_temp2.
14246 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14247 * lisp.h (case_temp1, case_temp2): Remove their decls.
14248 * character.h (ASCII_CHAR_P): Move from here ...
14249 * lisp.h: ... to here, so that the inline functions mentioned
14250 above can use them.
14252 * dired.c (directory_files_internal_unwind): Now static.
14254 * fileio.c (file_name_as_directory, directory_file_name):
14255 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14257 (file_name_as_directory): Use const pointers when appropriate.
14258 (Fexpand_file_name): Likewise. In particular, newdir might
14259 point at constant storage, so make it a const pointer.
14260 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14261 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14263 (Fset_file_times, Finsert_file_contents, auto_save_error):

14268 to avoid shadowing.
14270 * marker.c (bytepos_to_charpos): Remove; unused.
14272 * lisp.h (verify_bytepos, count_markers): New decls,
14273 so that gcc does not warn that these functions aren't declared.
14275 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14276 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14277 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14278 (copy_text): Remove unused local var.
14280 * filelock.c (within_one_second): Now static.
14281 (lock_file_1): Rename local to avoid shadowing.
14283 * buffer.c (fix_overlays_before): Mark locals as initialized.
14284 (fix_start_end_in_overlays): Likewise. This function should be
14285 simplified by using pointers-to-pointers, but that's a different
14287 (switch_to_buffer_1): Now static.
14288 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14289 (report_overlay_modification): Rename locals to avoid shadowing.
14291 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14292 Fix pointer signedness issue.
14293 (sys_subshell): Mark local as volatile if checking for lint,
14294 to suppress a gcc -Wclobbered warning that does not seem to be right.
14295 (MAXPATHLEN): Define only if needed.
14297 * process.c (serial_open, serial_configure): Move decls from here ...
14298 * systty.h: ... to here, so that they can be checked.
14300 * fns.c (get_random, seed_random): Move extern decls from here ...
14301 * lisp.h: ... to here, so that they can be checked.
14303 * sysdep.c (reset_io): Now static.
14304 (wait_for_termination_signal): Remove; unused.
14306 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14307 (copy_keymap_item, append_key, push_text_char_description):
14309 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14310 (DENSE_TABLE_SIZE): Remove; unused.
14311 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14312 (describe_map_tree):
14313 Rename locals to avoid shadowing.
14315 * keyboard.c: Declare functions static if they are not used elsewhere.

14337 if GCC considers string literals to be constants.
14339 * lisp.h (fatal_error_signal): Add decl, since it's exported.

14400 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
14401 These macros can no longer be used for assignment.
