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

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

527 (DATA_SEG_BITS): Use it.
528 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
529 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
530 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
531 not be usable in #if. This simplifies things.
533 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
535 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
537 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

540 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
541 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
542 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
543 Adjust to changes in lisp.h and emacs.c, by using
544 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
545 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
546 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
547 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
548 instead of gdb_valbits.
549 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
550 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
551 instead of gdb_array_mark_flag.
552 (xboolvector): Get size from $->size, not $->header.size.
553 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
554 (xreload, hook-run, hookpost-run): Remove.
555 * emacs.c: Include <verify.h>.
556 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
557 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
559 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
560 (gdb_USE_LSB_TAG): New enum constants.
561 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
562 Also define these as enum constants, so they're visible to GDB.
563 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
564 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
565 as constants, so they're visible to GDB.
566 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
567 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
568 Now enum constants, not macros, so they're visible to GDB.
569 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
570 more convenient now. All uses changed.
571 (VALMASK) [USE_LSB_TAG]: Also define in this case.
572 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
574 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

582 add argument, tune behavior, and adjust all callers.
584 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
586 Use typedef for EMACS_INT, EMACS_UINT.
587 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
588 than macros. This simplifies debugging in the usual case, since
589 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
590 and it allows expressions involving EMACS_INT casts.
591 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
593 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

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

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

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

763 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
764 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
765 'for_each_per_buffer_object_at'.
766 All uses changed. It's better to use upper-case for macros that

1401 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
1403 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
1405 Remove "#define unix" that is no longer needed (Bug#11905).
1406 * s/aix4-2.h (unix): Remove; no longer needed.
1408 EMACS_TIME simplification (Bug#11875).
1409 This replaces macros (which typically do not work in GDB)
1410 with functions, typedefs and enums, making the code easier to debug.
1411 The functional style also makes code easier to read and maintain.
1412 * systime.h: Include <sys/time.h> on all hosts, not just if
1413 WINDOWSNT, since 'struct timeval' is needed in general.
1414 (EMACS_TIME): Now a typedef, not a macro.
1415 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1417 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
1418 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
1419 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
1420 (EMACS_TIME_LE): Now functions, not macros.
1421 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1422 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1423 which are not functions. All uses rewritten to use:
1424 (make_emacs_time): New function.
1425 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1426 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1427 not functions. All uses rewritten to use the following, respectively:
1428 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1429 (add_emacs_time, sub_emacs_time): New functions.
1430 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1431 * fileio.c (Fcopy_file):
1432 * xterm.c (XTflash): Get the current time closer to when it's used.
1433 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1437 Simplify by avoiding confusing use of strncpy etc.
1438 * doc.c (Fsnarf_documentation):
1439 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
1440 * frame.c (Fmake_terminal_frame):
1441 * gtkutil.c (get_utf8_string):
1443 * nsmenu.m (ns_update_menubar):
1444 * regex.c (regerror):
1445 Prefer memcpy to strncpy and strncat when either will do.
1446 * fileio.c (Fsubstitute_in_file_name):
1447 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1448 (menu_separator_name_p):
1449 * nsmenu.m (ns_update_menubar):
1450 Prefer memcmp to strncmp when either will do.
1451 * nsterm.m: Include <ftoastr.h>.
1453 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1454 Prefer snprintf to strncpy.
1455 * nsterm.m (ns_term_init):
1456 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1457 * nsterm.m (ns_term_init):
1458 Avoid the need for strncpy, by using build_string or
1459 make_unibyte_string directly. Use dtoastr, not snprintf.
1460 * process.c (Fmake_network_process): Diagnose service names that
1461 are too long, rather than silently truncating them or creating
1462 non-null-terminated names.
1463 (Fnetwork_interface_info): Likewise, for interface names.
1464 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1465 Prefer sprintf to strncat.
1466 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1467 Prefer vsnprintf to vsprintf + strncpy.
1469 2012-07-10 Glenn Morris <rgm@gnu.org>
1471 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1472 Clarify fallback case.
1474 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1476 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1477 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1478 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1479 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1480 where argument type is known to be a Lisp_Cons.
1482 2012-07-10 Tom Tromey <tromey@redhat.com>
1484 * bytecode.c (BYTE_CODE_THREADED): New macro.
1485 (BYTE_CODES): New macro. Replaces all old byte-code defines.
1486 (enum byte_code_op): New type.
1487 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
1488 (exec_byte_code): Use them. Use token threading when applicable.
1490 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1492 Optimize pure C strings initialization.
1493 * lisp.h (make_pure_string): Fix prototype.
1494 (build_pure_c_string): New function, defined as static inline. This
1495 provides a better opportunity to optimize away calls to strlen when
1496 the function is called with compile-time constant argument.
1497 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1498 argument, adjust users accordingly. Use build_pure_c_string where
1500 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1501 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1502 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1504 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1506 Avoid calls to strlen in miscellaneous functions.
1507 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1508 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1509 * lread.c (openp): Likewise.
1511 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1513 Avoid calls to strlen in path processing functions.
1514 * fileio.c (file_name_as_directory): Add comment. Change to add
1515 srclen argument and return the length of result. Adjust users
1517 (directory_file_name): Fix comment. Change to add srclen argument,
1518 swap 1st and 2nd arguments to obey the common convention. Adjust
1520 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1522 2012-07-10 Glenn Morris <rgm@gnu.org>
1524 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1525 Move PENDING_OUTPUT_COUNT definition to configure.
1527 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1528 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1529 * s/gnu.h (DATA_START): Move definitions to configure.
1531 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1532 We include usg5-4-common.h, which defines them both.
1534 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1535 O_RDONLY already includes it).
1537 Stop ns builds setting the EMACSLOADPATH environment variable.
1538 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1539 Now it does not set EMACSLOADPATH, just returns the load-path string.
1540 * nsterm.h: Update accordingly.
1541 * lread.c [HAVE_NS]: Include nsterm.h.
1542 (init_lread) [HAVE_NS]: Use ns_load_path.
1543 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1545 2012-07-09 Glenn Morris <rgm@gnu.org>
1547 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1548 since the included bsd-common.h does so.
1550 Stop ns builds setting the EMACSPATH environment variable.
1551 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1552 (ns_init_paths): Do not set EMACSPATH.
1553 * nsterm.h (ns_exec_path): Add it.
1554 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1557 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1559 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1561 * process.c (wait_reading_process_output): 'waitchannels' was unset
1562 when read_kbd || !NILP (wait_for_cell); fix this.
1564 Add GCC-style 'const' attribute to functions that can use it.
1565 * character.h (char_resolve_modifier_mask):
1566 * keyboard.h (make_ctrl_char):
1567 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1568 (init_character_once, next_almost_prime, init_fns, init_image)
1569 (flush_pending_output, init_sound):
1570 * mem-limits.h (start_of_data):
1571 * menu.h (finish_menu_items):
1572 Add ATTRIBUTE_CONST.

1574 Declare the dummy function with ATTRIBUTE_CONST.
1575 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1576 Add decls with ATTRIBUTE_CONST.
1578 Minor improvements to make_formatted_string.
1579 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1580 where int is good enough, as vsprintf returns an int.
1581 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1583 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1585 Use make_formatted_string to avoid double length calculation.
1586 * lisp.h (make_formatted_string): New prototype.
1587 * alloc.c (make_formatted_string): New function.
1588 * buffer.c (Fgenerate_new_buffer_name): Use it.
1589 * dbus.c (syms_of_dbusbind): Likewise.
1590 * editfns.c (Fcurrent_time_zone): Likewise.
1591 * filelock.c (get_boot_time): Likewise.
1592 * frame.c (make_terminal_frame, set_term_frame_name)
1593 (x_report_frame_params): Likewise.
1594 * image.c (gs_load): Likewise.
1595 * minibuf.c (get_minibuffer): Likewise.
1596 * msdos.c (dos_set_window_size): Likewise.
1597 * process.c (make_process): Likewise.
1598 * xdisp.c (ensure_echo_area_buffers): Likewise.
1599 * xsettings.c (apply_xft_settings): Likewise.
1601 2012-07-09 Glenn Morris <rgm@gnu.org>
1603 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
1604 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
1605 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
1606 * nsterm.h (ns_etc_directory): Add it.
1607 * callproc.c [HAVE_NS]: Include nsterm.h.
1608 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1610 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1612 Move marker debugging code under MARKER_DEBUG.
1613 * marker.c (MARKER_DEBUG): Move marker debugging code under
1614 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1615 for bootstrap with --enable-checking (~3x slowdown reported
1616 by Juanma Barranquero <lekktu@gmail.com>).
1617 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1619 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1621 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1622 See <http://bugs.gnu.org/11825#29>.
1624 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1626 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1627 has no font, use the frame's font. (Bug#11813)
1628 (display_line): Add commentary about displaying truncation glyphs
1630 (produce_special_glyphs): Move here from term.c.
1632 * term.c (produce_special_glyphs): Move to xdisp.c.
1634 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1637 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1639 * xdisp.c (display_line): Avoid warning about implicit declaration
1642 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1644 * lisp.h: Remove empty conditional.
1646 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1648 * lread.c (load_path_check): Now static.
1650 Fix some minor --with-ns problems found by static checking.
1651 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1652 (x_set_font) [!HAVE_X_WINDOWS]:
1653 * image.c (xpm_load_image) [HAVE_NS]:
1654 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1655 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1656 Remove unused local.
1657 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1658 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1659 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1660 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1661 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1662 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1663 Fix pointer signedness problem.
1664 * xfaces.c (FRAME_X_FONT_TABLE):
1665 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1667 2012-07-07 Glenn Morris <rgm@gnu.org>
1669 * lread.c (load_path_check): New function, split from init_lread.
1670 (init_lread): Reorganize. Motivation:
1671 If EMACSLOADPATH is set, check/warn about that rather than the
1672 defaults, which we are not going to use. Hence we can remove
1673 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1674 Don't warn if site-lisp directories are missing.
1675 If not installed, start from a blank load-path, since
1676 PATH_LOADSEARCH refers to the eventual installation directories.
1678 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1680 Support truncation and continuation glyphs on GUI frames, when
1681 fringes are disabled. (Bug#11832)
1682 * xdisp.c (init_iterator): Get dimensions of truncation and
1683 continuation glyphs even if on GUI frames. Adjust
1684 it->last_visible_x on GUI frames when the left or right fringes,
1685 or both, are absent.
1686 (start_display, move_it_in_display_line_to): Handle the case of a
1687 GUI frame without a fringe to display continuation or truncation
1689 (insert_left_trunc_glyphs): Support GUI frames: make sure
1690 truncation glyphs overwrite enough glyphs from the current line to
1691 have sufficient space in pixels.
1692 (display_line): Support truncation and continuation glyphs on GUI
1693 frames. If some spare pixels are left on the line after inserting
1694 the truncation glyphs, fill that space with a stretch glyph of a
1695 suitably computed width.
1697 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1698 produce_glyphs, to support GUI sessions.
1700 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1702 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1704 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1706 Do not require float-time's arg to fit in time_t (Bug#11825).
1707 This works better on hosts where time_t is unsigned, and where
1708 float-time is applied to the (negative) difference between two times.
1709 * editfns.c (decode_time_components): Last arg is now double *,
1710 not int *, and means to store all the result as a double, without
1711 worrying about whether the seconds part fits in time_t.
1712 All callers changed.
1713 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1714 All callers changed.
1715 (Ffloat_time): Do not fail merely because the specified time falls
1716 outside of time_t range.
1718 2012-07-07 Glenn Morris <rgm@gnu.org>
1720 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1721 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1722 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1724 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1726 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1727 Update dependencies.
1729 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1731 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1733 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1734 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1735 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1736 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1737 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1738 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1740 * xfont.c (compare_font_names): Redo to omit the need for casts.
1742 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1744 * xfns.c (Fx_change_window_property): Doc fix.
1745 * w32fns.c (Fx_change_window_property): Doc fix.
1747 * w32fns.c (Fx_window_property): Accept the same arguments as the
1748 X Windows version. Doc fix.
1749 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1751 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1752 Eli Zaretskii <eliz@gnu.org>
1754 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1755 Windows-specific code from nt/config.nt moved here.
1756 Obsolete settings removed.
1758 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1760 * process.c: Avoid unnecessary calls to gettime.
1761 (wait_reading_process_output): Don't get the time of day
1762 when gobbling data immediately and not waiting, as there's no need
1763 for it in that case. This removes a FIXME.
1765 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1767 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1768 is defined (Bug#11768).
1770 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1772 Fix marker debugging code.
1773 * marker.c (byte_char_debug_check): Do not perform the check
1774 if buffer is not multibyte.
1775 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1776 Call byte_char_debug_check with correct arguments.
1778 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1780 Compile marker debugging code only if ENABLE_CHECKING is defined.
1781 * marker.c (byte_char_debug_check, count_markers):
1782 Use only if ENABLE_CHECKING is defined.
1783 (byte_debug_flag): Remove.
1784 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1785 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1787 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1789 Avoid code repetition in marker-related functions.
1790 * marker.c (attach_marker): New function.
1791 (Fset_marker, set_marker_restricted, set_marker_both)
1792 (set_marker_restricted_both): Use it.
1793 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1794 Consistently rename charno to charpos.
1795 (marker_position): Add eassert.
1796 (marker_byte_position): Convert to eassert.
1798 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1800 Simplify list operations in unchain_overlay and unchain_marker.
1801 * buffer.c (unchain_overlay): Simplify. Add comment.
1802 * marker.c (unchain_marker): Simplify. Fix comments.
1804 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1806 Introduce fast path for the widely used marker operation.
1807 * alloc.c (build_marker): New function.
1808 * lisp.h (build_marker): New prototype.
1809 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1810 * composite.c (autocmp_chars): Likewise.

1812 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1813 (save_restriction_save): Use build_marker.
1814 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1815 * window.c (save_window_save): Likewise.
1817 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1819 Do not use Fdelete_overlay in delete_all_overlays
1820 to avoid redundant calls to unchain_overlay.
1821 * buffer.c (drop_overlay): New function.
1822 (delete_all_overlays, Fdelete_overlay): Use it.
1823 * minibuf.c (get_minibuffer): Fix comment.
1825 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1827 Port to OpenBSD 5.1 amd64.
1828 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1829 This is needed for OpenBSD, and should be harmless on all BSD systems.
1830 Also, include <sys/sysctl.h>, as it should be available on all
1831 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1832 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1833 use p_pid member, not kp_proc.pid.
1835 2012-07-06 Glenn Morris <rgm@gnu.org>
1837 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1839 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1841 More xmalloc and related cleanup.

1850 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1852 Omit needless casts involving void * pointers and allocation.
1853 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1854 as the former is more robust if P's type is changed.
1855 Prefer xzalloc to xmalloc + memset 0.
1856 Simplify malloc-or-realloc to realloc.
1857 Don't worry about xmalloc returning a null pointer.
1858 Prefer xstrdup to xmalloc + strcpy.
1859 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1861 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1862 alloca of a constant.
1864 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1866 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1867 hscroll is larger than the line width. Fixes long and futile
1868 looping inside extend_face_to_end_of_line (on a TTY) producing
1869 glyphs that are not needed and thrown away.
1871 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

1883 not defined (Bug#11768).
1884 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1885 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1886 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1887 followed by gtk_box_set_homogeneous (Bug#11768).
1888 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1889 (update_theme_scrollbar_width, xg_create_scroll_bar):
1890 Use gtk_scrollbar_new (Bug#11768).
1891 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

1899 * xdisp.c (window_hscroll_limited): New function.
1900 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1901 coordinates when window's hscroll is set to insanely large

1968 Problem reported by Troels Nielsen in
1969 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

1973 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1974 This should be fixed in a better way; see Eli Zaretskii in
1975 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1976 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1978 * fileio.c (time_error_value): Rename from special_mtime.
1979 The old name's problems were noted by Eli Zaretskii in
1980 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1982 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1983 This variable's comment says Emacs needs at least one GDB-visible
1984 symbol of type enum pvec_type, to work around GDB problems.
1985 The symbol's value doesn't matter.
1987 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1988 that causes compilation to fail on pre-C99 compilers.
1990 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1992 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1998 headers for buffer_defaults and buffer_local_symbols.
1999 Reported by Juanma Barranquero <lekktu@gmail.com>.
2001 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2003 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2004 * lisp.h (enum pvec_type): Use fewer bits.
2005 (PSEUDOVECTOR_SIZE_BITS): New constant.
2006 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2007 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2008 change in pvec_type.
2009 (PSEUDOVECTOR_TYPEP): New macro.
2010 (TYPED_PSEUDOVECTORP): Use it.
2011 * fns.c (internal_equal): Adapt code to extract pvectype.

2013 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2014 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2015 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2016 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2017 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2018 abusing vector->header.next.nbytes.
2019 (live_vector_p): Use PVEC_TYPE.
2020 (mark_object): Adapt code to extract pvectype. Use switch.
2022 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2024 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2025 Tighten new eassert a bit.
2027 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2029 Fix compilation with --enable-gcc-warnings and -O1
2031 * doprnt.c (doprnt): Change type of tem to int, initialize
2032 to avoid compiler warning. Add eassert.
2033 * search.c (simple_search): Initialize match_byte to avoid
2034 compiler warning. Add eassert.
2036 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2038 Avoid weird behavior with large horizontal scrolls.
2039 Without this change, for example, large hscroll values would
2040 mess up Emacs's display on Fedora 15 x86, presumably due to
2041 overflows in int calculations in the display code.
2042 Also, if buffers had long lines, Emacs would freeze.
2043 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2044 (set_window_hscroll): New function, containing the old guts of
2045 Fset_window_hscroll. Return the clipped value.
2046 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2047 This avoids the need to check against PTRDIFF_MAX.
2049 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2051 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2053 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2055 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2057 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2058 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2059 since GCC 4.4.6 issues a bogus warning for them.
2061 Fix bugs in file timestamp newness comparisons.
2062 * fileio.c (Ffile_newer_than_file_p):
2063 * lread.c (Fload): Use full timestamp resolution of files,
2064 not just the 1-second resolution, so that files that are only
2065 slightly newer still count as newer.
2066 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2067 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2069 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2071 * fileio.c: Improve handling of file time marker. (Bug#11852)
2072 (special_mtime): New function.
2073 (Finsert_file_contents, Fverify_visited_file_modtime):
2074 Use it to set special mtime values consistently.
2076 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2078 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2079 marker for non-existing file. (Bug#11852)
2081 2012-07-03 Glenn Morris <rgm@gnu.org>
2083 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2084 and did not make it into globals.h).
2086 2012-07-03 Tom Tromey <tromey@redhat.com>
2088 * window.c (Fset_window_margins, Fset_window_fringes)
2089 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2090 * textprop.c (Fprevious_property_change): No longer static.
2091 * syntax.c (Fsyntax_table_p): No longer static.
2092 * process.c (Fget_process, Fprocess_datagram_address): No longer

2112 * dispextern.h: Remove EXFUNs.
2113 * intervals.h: Remove EXFUNs.
2114 * fontset.h: Remove EXFUN.
2115 * font.h: Remove EXFUNs.
2116 * dosfns.c (system_process_attributes): Remove EXFUN.
2117 * keymap.h: Remove EXFUNs.
2118 * lisp.h: Remove EXFUNs.
2119 * w32term.h: Remove EXFUNs.
2120 * window.h: Remove EXFUNs.
2121 * xsettings.h: Remove EXFUN.
2122 * xterm.h: Remove EXFUN.
2124 2012-07-03 Glenn Morris <rgm@gnu.org>
2126 * lisp.h (Frandom): Make it visible to C.
2127 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2128 buffer for invisible buffers. (Bug#1229)
2130 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2132 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2133 values which aren't power of 2.
2134 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2135 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2138 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2140 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2142 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2144 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2146 * alloc.c (allocate_vector_block): Remove redundant
2147 calls to mallopt if DOUG_LEA_MALLOC is defined.
2148 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2149 avoid calls to mallopt if zero_vector is returned.
2151 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2153 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2154 is enabled, avoid dereferencing NULL current_sblock if
2157 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2159 Cleanup basic buffer management.
2160 * buffer.h (struct buffer): Change layout to use generic vector
2161 marking code. Fix some comments. Change type of 'clip_changed'
2162 to bitfield. Remove unused #ifndef old.
2163 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2164 (GET_OVERLAYS_AT): Fix indentation.
2165 (for_each_per_buffer_object_at): New macro.
2166 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2168 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2169 * alloc.c (allocate_buffer): Adjust to match new layout of
2170 struct buffer. Fix comment.
2171 (mark_overlay): New function.

2173 Lisp area of struct buffer.
2174 (mark_object): Use it. Adjust marking of misc objects
2175 and related comments.
2177 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2179 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2180 wrapper that is not needed because the wrapped code is a no-op (zero
2181 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2182 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2184 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2186 * alloc.c (mark_buffer): Simplify. Remove prototype.
2187 (mark_object): Add comment. Reorganize marking of vector-like
2188 objects. Use CHECK_LIVE for all vector-like objects except buffers
2189 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2190 redundant calls to mark_vectorlike for bool vectors.
2192 2012-06-30 Glenn Morris <rgm@gnu.org>
2194 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2196 * epaths.in (PATH_SITELOADSEARCH): New.
2197 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2198 This is rather than relying on --enable-locallisppath elements
2199 having "site-lisp" in their names. (Bug#10208#25, 11658)
2201 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2203 * w32proc.c (sys_select): Accept and ignore one more argument.
2205 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2207 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2208 (pselect) [!MS_DOS]: Redirect to sys_select.
2210 * sysdep.c: Don't include dos.h and dosfns.h.
2212 * process.c (sys_select):
2213 * msdos.c (sys_select): Accept one more argument and ignore it.
2215 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2216 adapt data types and code to that.
2219 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2220 which clashes with the gnulib function of the same name.
2222 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2224 * font.c (font_style_to_value, font_style_symbolic)
2225 (font_prop_validate_style): Add type checks for values in
2228 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2230 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2233 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2235 * xdisp.c (try_window_id): Undo last change.
2237 * w32.c (getwd): Adjust commentary about startup_dir.
2238 (init_environment): Always call sys_access, even in non-MSVC
2239 builds. Don't chdir to the directory of the Emacs executable.
2240 This undoes code from 1997 which was justified by the need to
2241 "avoid conflicts when removing and renaming directories". But its
2242 downside was that every relative file name was being interpreted
2243 relative to the directory of the Emacs executable, which can never
2244 be TRT. In particular, it broke sys_access when called with
2245 relative file names.
2246 (sys_access): Map GetLastError to errno.
2248 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2250 * window.h (struct window): Change type of 'fringes_outside_margins'
2251 to bitfield. Fix comment. Adjust users accordingly.

2254 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2257 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2259 * gnutls.c (emacs_gnutls_handshake):
2260 Add QUIT to make the loop interruptible.
2262 2012-06-29 Glenn Morris <rgm@gnu.org>
2264 * charset.c (init_charset): Make lack of etc/charsets fatal.
2266 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2268 * editfns.c (region_limit): Fix type mismatch.
2270 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2272 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2273 undefined. Convert from xassert to eassert.
2274 * nsmenu.m: Convert from xassert to eassert.
2275 * nsterm.m: Likewise.
2277 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2279 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2281 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2283 Avoid integer overflow on scroll-left and scroll-right.
2284 * window.c (HSCROLL_MAX): New macro.
2285 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2286 overflow when requested scroll falls outside ptrdiff_t range.
2288 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2290 * window.h (struct window): Change type of 'hscroll',
2291 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2292 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2293 Adjust users accordingly.
2294 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2295 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2296 from EMACS_INT to ptrdiff_t.
2297 (make_window): Omit redundant initialization.
2299 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2301 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2303 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2305 * window.h (struct window): Change type of 'use_time' and
2306 'sequence_number' from Lisp_Object to int.
2307 * frame.c (make_frame): Adjust users accordingly.
2308 * print.c (print_object): Likewise.
2309 * window.c (select_window, Fwindow_use_time, make_parent_window)
2310 (make_window): Likewise.
2312 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2314 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2315 enabled with --enable-checking=[all,glyphs] configure option.
2316 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2317 adjust comments accordingly.
2318 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be

2440 Use sprintf return value instead of invoking strlen on result.
2441 In the old days this wasn't portable, since some sprintf
2442 implementations returned char *. But they died out years ago and
2443 Emacs already assumes sprintf returns int.
2444 Similarly for float_to_string.

2629 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2631 Support higher-resolution time stamps (Bug#9000).
2632 The time stamps are only nanosecond-resolution at the C level,
2633 since that's the best that any real-world system supports now.
2634 But they are picosecond-resolution at the Lisp level, as that's
2635 easy, and leaves room for future OS improvements.
2637 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2640 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2641 Don't get current time unless it's needed.
2643 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2644 now provides it if it's absent.
2645 (start_atimer): Port to higher-res time stamps.
2646 Check for time stamp overflow. Don't get current time more
2647 often than is needed.
2649 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2650 Include systime.h, not time.h.
2651 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2653 * dired.c: Include stat-time.h.
2654 (Ffile-attributes): File times now have higher resolution.

2657 (struct image): Timestamp now has higher resolution.
2659 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2660 has at least microseconds now. All uses removed.
2661 (update_frame, update_single_window, update_window, update_frame_1)
2662 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2664 * editfns.c (time_overflow): Now extern.
2665 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2666 (float-time, Fformat_time_string, Fcurrent_time_string)

2670 (decode_time_components, lisp_seconds_argument): New functions.
2671 (make_time): Now static.
2672 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2673 Report an error if the time is invalid, rather than having the caller
2676 * fileio.c: Include <stat-time.h>
2677 (Fcopy_file): Copy higher-resolution time stamps.
2678 Prefer to set the time stamp via a file descriptor if that works.
2679 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2680 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2681 (Fvisited_file_modtime, Fset_visited_file_modtime):
2682 Support higher-resolution time stamps.
2684 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2686 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2688 * image.c (prepare_image_for_display, clear_image_cache)
2689 (lookup_image): Port to higer-resolution time stamps.
2691 * keyboard.c (start_polling, bind_polling_period):
2692 Check for time stamp overflow.
2693 (read_char, kbd_buffer_get_event, timer_start_idle)
2694 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2695 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2696 Port to higher-resolution time stamps. Do not assume time_t is signed.
2697 (decode_timer): New function. Timers are now vectors of length 9,
2698 not 8, to accommodate the picosecond component.
2699 (timer_check_2): Use it.
2701 * nsterm.m (select_timeout, timeval_subtract): Remove.
2702 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2703 as they're a bit more accurate and handle overflow better.
2704 (ns_select): Change prototype to be compatible with pselect.
2705 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2706 * nsterm.h (ns_select): Adjust prototype.
2708 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2709 us-resolution time stamps.
2710 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2712 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2714 * lisp.h (time_overflow): New decl.
2715 (wait_reading_process_output): First arg is now intmax_t, not int,
2716 to accommodate larger waits.
2718 * process.h (struct Lisp_Process.read_output_delay):
2719 Now counts nanoseconds, not microseconds.
2720 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2722 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2723 (wait_reading_process_output):
2724 Port to ns-resolution time stamps.
2725 (Faccept_process_output, wait_reading_process_output):
2726 Check for time stamp overflow. Do not assume time_t is signed.
2727 (select_wrapper): Remove; we now use pselect.
2728 (Fprocess_attributes): Now generates ns-resolution time stamps.
2730 * sysdep.c: Include utimens.h. Don't include utime.h
2731 or worry about struct utimbuf; gnulib does that for us now.
2732 (gettimeofday): Remove; gnulib provides a substitute.
2733 (make_timeval): New function.
2734 (set_file_times): Now sets ns-resolution time stamps.
2735 New arg FD; all uses changed.
2736 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2737 (system_process_attributes):
2738 Now returns ns-resolution time stamp. All uses changed.
2739 Check for time stamp overflow.
2741 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2742 provides a substitute now.
2744 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2745 since it guarantees struct timespec.
2746 (EMACS_TIME): Now struct timespec, so that we can support
2747 ns-resolution time stamps.
2748 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2749 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2750 (EMACS_USECS): Remove.
2751 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2752 so multiply the arg by 1000 before storing it.
2753 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2755 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2756 Port to ns-resolution time stamps.
2757 (EMACS_TIME_NEG_P): Remove; replaced by....
2758 (EMACS_TIME_SIGN): New macro.
2759 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2760 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

2762 (make_timeval, make_lisp_time, decode_time_components): New decls.
2763 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2764 that it mishandled time_t overflow. You can't compare by subtracting!
2765 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2766 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2768 * term.c: Include <sys/time.h>.
2769 (timeval_to_Time): New function, for proper overflow wraparound.
2770 (term_mouse_position, term_mouse_click): Use it.
2772 * undo.c (record_first_change): Support higher-resolution time stamps
2774 (Fprimitive_undo): Use them when restoring time stamps.
2776 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2777 (w32_get_internal_run_time):
2778 Port to higher-resolution Emacs time stamps.
2779 (ltime): Now accepts single 64-bit integer, as that's more convenient
2782 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2784 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2785 for compatibility with pselect. Support ns-resolution time stamps.
2787 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2789 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2790 Check for time stamp overflow, and support ns-resolution time stamps.
2792 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2793 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2794 (timeval_subtract): Remove; no longer needed.
2795 (XTflash, XTring_bell, x_wait_for_event):
2796 Port to ns-resolution time stamps. Don't assume time_t is signed.
2798 2012-06-22 Chong Yidong <cyd@gnu.org>

2858 gets killed during executing of this function (Bug#11665).

2891 * coding.c (produce_chars): Use ptrdiff_t, not int.
2893 * xterm.c (x_draw_underwave): Check for integer overflow.
2894 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3079 code works fine either way, and efficiency is not a concern here,
3080 as the union type is for debugging, not for production.
3081 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3082 Use an inline function on all platforms when using the union type,
3083 since this is simpler and 'static inline' can be used portably

3228 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3229 would mishandle a string argument "Xc" if X was a multibyte
3230 character of length 2: it would truncate after X's first byte
3231 rather than including all of X.

3278 and DEFVAR it. Update all users.
3280 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
3282 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3284 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3285 Convert pctcpu and pctmem to Lisp float properly.
3286 Let the compiler fold better, as 100.0/0x8000 is exact.
3288 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3290 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3293 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3295 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3297 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3299 For a 'struct window', replace some Lisp_Object fields to
3300 bitfields where appropriate, remove unused fields.
3301 * window.h (struct window): Remove unused 'last_mark_x' and
3302 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3303 change it's type from Lisp_Object to bitfield.
3304 Change type of 'force_start', 'optional_new_start',
3305 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3306 fields from Lisp_Object to bitfield. Adjust users accordingly.
3308 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3310 Pacify gcc -Wdouble-precision when using Xaw.
3311 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3312 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3313 Use 'float' consistently, rather than 'float' in most places
3314 and 'double' in a couple of places.
3316 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3318 * xdisp.c (handle_stop): Detect whether we have overlay strings
3319 loaded by testing it->current.overlay_string_index to be
3320 non-negative, instead of checking whether n_overlay_strings is
3321 positive. (Bug#11587)
3323 2012-05-31 Chong Yidong <cyd@gnu.org>
3325 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3327 * doc.c (Fsubstitute_command_keys): Doc fix.
3329 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3331 * search.c (search_buffer): Remove calls to
3332 r_alloc_inhibit_buffer_relocation, as it is now called by
3333 maybe_unify_char, which was the cause of relocation of buffer text
3336 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3338 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3339 for the duration of call to load_charset, to avoid problems with
3340 callers of maybe_unify_char that access buffer text through C
3343 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3344 decrement the inhibition flag, instead of just setting or
3347 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3349 Remove obsolete '#define static' cruft.
3350 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3351 This #undef was "temporary" in 2000; it is no longer needed
3352 now that '#define static' has gone away.
3353 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3354 (gray_bitmap_bits): Remove; no longer needed.
3355 All uses replaced with definiens.
3356 * xterm.c: Include "bitmaps/gray.xbm".
3358 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3360 Clean up __executable_start, monstartup when --enable-profiling.
3361 The following changes affect the code only when profiling.
3362 * dispnew.c (__executable_start): Rename from safe_bcopy.
3363 Define only on platforms that need it.
3364 * emacs.c: Include <sys/gmon.h> when profiling.
3365 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3366 (__executable_start): Remove decl, since lisp.h does it now.
3367 (safe_bcopy): Remove decl; no longer has that name.
3368 (main): Coalesce #if into single bit of code, for simplicity.
3369 Cast pointers to uintptr_t, since standard libraries want integers
3371 * lisp.h (__executable_start): New decl.
3373 2012-05-31 Glenn Morris <rgm@gnu.org>
3375 * image.c (Fimagemagick_types): Doc fix.
3377 2012-05-30 Jim Meyering <meyering@redhat.com>
3379 * callproc.c (Fcall_process_region): Include directory component
3380 in mkstemp error message (Bug#11586).
3382 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3384 * alloc.c, lisp.h (make_pure_vector): Now static.
3386 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

3393 * lisp.h (Qdefun): Remove.
3394 * lread.c (read1): Tiny simplification.
3396 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3398 Do not create empty overlays with the evaporate property (Bug#9642).
3399 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3400 Bug#9642, but explicitly check that the buffer the overlay would
3401 be moved to is live and rearrange lines to make sure that errors
3402 will not put the overlay in an inconsistent state.
3403 (Fdelete_overlay): Cosmetics.
3405 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3407 * w32term.c (my_bring_window_to_top): New function.
3408 (x_raise_frame): Use handle returned by DeferWindowPos, which
3409 could be different from the original one.

3413 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3414 by calling BringWindowToTop.
3416 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3417 (WM_EMACS_END): Increase by one.
3419 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3421 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3422 This avoids undefined behavior that might cause the eassert
3423 to not catch an out-of-range value.
3425 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3427 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
3428 Update dependencies.
3430 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3432 * bidi.c (bidi_mirror_char): Fix last change.
3434 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
3436 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
3437 when referring to sectname field in printf format.
3439 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3441 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3442 Only r_alloc_inhibit_buffer_relocation needed to be added;
3443 the others were already declared.
3445 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3446 before checking whether it's out of range. Put the check inside
3448 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3450 2012-05-27 Ken Brown <kbrown@cornell.edu>
3452 * callproc.c (Fcall_process): Restore a line that was accidentally
3453 commented out in the 2011-02-13 change (bug#11547).
3455 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3457 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3458 defined on ralloc.c.
3460 * buffer.c [REL_ALLOC]: Remove prototypes of
3461 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3462 they are now on lisp.h.
3464 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3466 * search.c (search_buffer): Use it to inhibit relocation of buffer
3467 text while re_search_2 is doing its job, because re_search_2 is
3468 passed C pointers to buffer text. (Bug#11519)
3470 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3473 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3474 state after an additional call to move_it_in_display_line_to, keep
3475 the values of it->max_ascent and it->max_descent found for the
3477 (pos_visible_p): Revert the comparison against bottom_y to what it
3478 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3481 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3483 Fix coding-related core dumps with gcc -ftrapv.
3484 The code was computing A - B, where A and B are pointers, and B is
3485 random garbage. This can lead to core dumps on platforms that
3486 have special pointer registers, and it also leads to core dumps on
3487 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3488 A - B only when B is initialized properly.
3489 * coding.c (coding_set_source, coding_set_destination): Return void.
3490 (coding_change_source, coding_change_destinations): New functions,
3491 with the old behaviors of coding_set_source and coding_set_destination.
3492 All callers that need an offset changed to use these new functions.
3494 2012-05-26 Glenn Morris <rgm@gnu.org>
3496 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3498 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3500 Extend mouse support on W32 text-mode console.
3501 * xdisp.c (draw_row_with_mouse_face):
3502 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3504 * w32console.c: Include window.h.
3505 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3507 (initialize_w32_display): Initialize mouse-highlight data.
3509 * w32inevt.c: Include termchar.h and window.h.
3510 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3511 moves, call note_mouse_highlight. If help_echo changed, call
3512 gen_help_event to produce help-echo message in the echo area.
3513 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3516 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3518 * lread.c (read1): Simplify slightly to avoid an overflow warning
3519 with GCC 4.7.0 on x86-64.
3521 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3523 * bidi.c (bidi_mirror_char): Revert last change: an int is
3524 definitely wide enough here.
3526 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3528 Fix integer width and related bugs (Bug#9874).
3529 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3530 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3531 (string_bytes, check_sblock, allocate_string_data):
3532 (compact_small_strings, Fmake_bool_vector, make_string)
3533 (make_unibyte_string, make_multibyte_string)
3534 (make_string_from_bytes, make_specified_string)
3535 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3536 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3538 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3539 (allocate_pseudovector):
3540 Use int, not EMACS_INT, where int is wide enough.
3541 (inhibit_garbage_collection, Fgarbage_collect):
3542 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3543 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3544 int might not be wide enough.
3545 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3546 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3547 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3548 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3549 (bidi_level_of_next_char, bidi_move_to_visually_next):
3550 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3551 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3552 (Fkill_buffer, Fset_buffer_major_mode)
3553 (advance_to_char_boundary, Fbuffer_swap_text)
3554 (Fset_buffer_multibyte, overlays_at, overlays_in)
3555 (overlay_touches_p, struct sortvec, record_overlay_string)
3556 (overlay_strings, recenter_overlay_lists)
3557 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3558 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3559 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3560 (Foverlay_recenter, last_overlay_modification_hooks_used)
3561 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3562 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3563 (validate_region): Omit unnecessary test for b <= e,
3564 since that's guaranteed by the previous test.
3565 (adjust_overlays_for_delete): Avoid pos + length overflow.
3566 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3567 (report_overlay_modification):
3568 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3569 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3570 Omit pointer cast, which isn't needed anyway, and doesn't work
3571 after the EMACS_INT -> ptrdiff_t change.
3572 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3573 * buffer.h: Adjust decls to match defn changes elsewhere.
3574 (struct buffer_text, struct buffer):
3575 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3576 Use EMACS_INT, not int, where int might not be wide enough.
3577 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3578 not int, to avoid needless 32-bit limit on 64-bit hosts.
3579 (exec_byte_code): Use tighter memory-full test, one that checks
3580 for alloca overflow. Don't compute the address of the object just
3581 before an array, as that's not portable. Use EMACS_INT, not
3582 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3583 * callint.c (Fcall_interactively):
3584 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3585 * callproc.c (call_process_kill, Fcall_process):
3586 Don't assume pid_t fits into an Emacs fixnum.
3587 (call_process_cleanup, Fcall_process, child_setup):
3588 Don't assume pid_t fits into int.
3589 (call_process_cleanup, Fcall_process, delete_temp_file)
3590 (Fcall_process_region):
3591 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3592 (Fcall_process): Simplify handling of volatile integers.
3593 Use int, not EMACS_INT, where int will do.
3594 * casefiddle.c (casify_object, casify_region, operate_on_word)
3595 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3596 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3597 (casify_object): Avoid integer overflow when overallocating buffer.
3598 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3599 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3600 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3601 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3602 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3603 integers are now checked earlier. All uses replaced with XINT.
3605 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3606 For CCL_MapSingle, check that content and value are in int range.
3607 (ccl_driver, Fregister_code_conversion_map):
3608 Check that Vcode_version_map_vector is a vector.
3609 (resolve_symbol_ccl_program): Check that vector header is in range.
3610 Always copy the vector, so that we can check its contents reliably
3611 now rather than having to recheck each instruction as it's being
3612 executed. Check that vector words fit in 'int'.
3613 (ccl_get_compiled_code, Fregister_ccl_program)
3614 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3615 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3616 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3617 contents are in range.
3618 (Fccl_execute_on_string): Check that status is in range.
3619 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3620 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3621 Accept and return EMACS_INT, not int, because callers can pass values
3623 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3624 (multibyte_chars_in_text, parse_str_as_multibyte)
3625 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
3626 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3627 (string_escape_byte8, Fget_byte):
3628 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3629 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3630 avoid mishandling large integers.
3631 * character.h: Adjust decls to match defn changes elsewhere.
3632 * charset.c (load_charset_map_from_file, find_charsets_in_text)
3633 (Ffind_charset_region):
3634 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3635 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
3636 (load_charset_map_from_vector, Fdefine_charset_internal):
3637 Don't assume fixnum fits in int.
3638 (load_charset_map_from_vector, Fmap_charset_chars):
3639 Remove now-unnecessary CHECK_NATNUMs.
3640 (Fdefine_charset_internal): Check ranges here, more carefully.
3641 Don't rely on undefined behavior with signed left shift overflow.
3642 Don't assume unsigned int fits into fixnum, or that fixnum fits
3643 into unsigned int. Don't require max_code to be a valid fixnum;
3644 that's not true for gb10830 4-byte on a 32-bit host. Allow
3645 invalid_code to be a cons, for the same reason. Require code_offset
3646 to be a character. Avoid int overflow if max_char is close
3648 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3649 this is intended anyway and avoids some undefined behavior.
3650 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3651 INDEX_TO_CODE_POINT, as that's what it expects.
3652 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3653 * charset.h (DECODE_CHAR): Return int, not unsigned;
3654 this is what was intended anyway, and it avoids undefined behavior.
3655 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3656 integer-overflow issues.
3657 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3658 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3659 where the argument is EMACS_INT, and this behavior is not intended.
3660 * chartab.c (Fmake_char_table, Fset_char_table_range)
3661 (uniprop_get_decoder, uniprop_get_encoder):
3662 Don't assume fixnum fits in int.
3663 * cmds.c (move_point): New function, that does the gist of
3664 Fforward_char and Fbackward_char, but does so while checking
3665 for integer overflow more accurately.
3666 (Fforward_char, Fbackward_char): Use it.
3667 (Fforward_line, Fend_of_line, internal_self_insert)
3668 (internal_self_insert):
3669 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3670 Fix a FIXME, by checking for integer overflow when calculating
3671 target_clm and actual_clm.
3672 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

4414 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4415 and `display_arg' (bug#9754).
4417 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4419 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4421 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4422 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4424 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4426 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4428 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4429 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4431 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4432 reference to image_cache->refcount.
4433 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4435 2012-05-17 Juri Linkov <juri@jurta.org>
4437 * search.c (Fword_search_regexp, Fword_search_backward)
4438 (Fword_search_forward, Fword_search_backward_lax)
4439 (Fword_search_forward_lax): Move functions to isearch.el
4440 (bug#10145, bug#11381).
4442 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4444 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4446 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4448 * lread.c (init_obarray): Declare Qt and Qnil as special.
4450 2012-05-14 Glenn Morris <rgm@gnu.org>
4452 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4453 Put "libexec" before "bin", for the sake of init_callproc_1.
4455 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4457 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4459 * unexaix.c: Port to more-recent AIX compilers.
4460 (report_error, report_error_1, make_hdr, copy_sym)
4461 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4462 Make arguments const char *, not char *, to avoid violations of C
4463 standard and to fix some AIX warnings reported by Gilles Pion.
4465 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4467 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4468 already have overlays loaded.
4469 (handle_single_display_spec): Before returning without displaying
4470 fringe bitmap, synchronize the bidi iterator with the main display
4471 iterator, by calling iterate_out_of_display_property.
4472 (iterate_out_of_display_property): Detect buffer iteration by
4473 testing that it->string is a Lisp string.
4474 (get_next_display_element): When the current object is exhausted,
4475 and there's something on it->stack, call set_iterator_to_next to
4476 proceed with what's on the stack, instead of returning zero.
4477 (set_iterator_to_next): If called at the end of a Lisp string,
4478 proceed to consider_string_end without incrementing string
4479 position. Don't increment display vector index past the end of
4480 the display vector. (Bug#11417)
4481 (pos_visible_p): Don't report a position visible when move_it_to
4482 stopped at the last line of window, which happens to be scanned
4483 backwards by the bidi iteration. (Bug#11464)
4485 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4487 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4488 and right-margin display specs even if the spec is invalid or we
4489 are on a TTY, and thus unable to display on the fringes.
4490 That's because the text with the property will not be displayed anyway,
4491 so we need to signal to the caller that this is a "replacing"
4492 display spec. This fixes display when the spec is invalid or we
4495 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4497 * unexaix.c (make_hdr): Fix typo in prototype.
4498 This bug broke the build on AIX. Problem reported by Gilles Pion.
4500 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4502 * keyboard.c (kbd_buffer_get_event): Read special events also in
4503 batch mode. (Bug#11415)
4505 2012-05-12 Glenn Morris <rgm@gnu.org>
4507 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4509 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4511 * lisp.mk (lisp): Add newcomment.elc.
4513 2012-05-12 Glenn Morris <rgm@gnu.org>
4515 * Makefile.in (MKDIR_P): New, set by configure.
4516 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4518 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4520 Remove unused function hourglass_started.
4521 * dispextern.h (hourglass_started):
4522 * w32fns.c (hourglass_started):
4523 * xdisp.c (hourglass_started): Remove.
4525 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4527 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4528 Update dependencies.
4530 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4532 * xgselect.c (xg_select): Put maxfds+1 into a var.
4533 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4535 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4537 2012-05-10 Dave Abrahams <dave@boostpro.com>
4539 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4540 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4542 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4544 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4545 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4546 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4547 Initialize xd_registered_buses.
4549 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4551 Untag more efficiently if USE_LSB_TAG.
4552 This is based on a proposal by YAMAMOTO Mitsuharu in
4553 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4554 For an admittedly artificial (nth 8000 longlist) benchmark on
4555 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4556 Emacs's overall text size by 1%.
4557 * lisp.h (XUNTAG): New macro.
4558 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4559 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4560 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4561 * eval.c (Fautoload):
4562 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4563 * frame.h (XFRAME): Use XUNTAG.
4565 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4566 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4567 Remove unportable assumptions about print widths of types like
4569 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4570 intptr_t when converting between pointer and integer, to avoid GCC
4571 warnings about wrong width.
4573 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4575 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4576 stack for each reader_thread, instead of defaulting to 8MB
4577 determined by the linker. This avoids failures in creating
4578 subprocesses on Windows 7, see the discussion in this thread:
4579 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4581 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4583 Fix up display of the *Minibuf-0* buffer in the mini window.
4584 * keyboard.c (read_char): Don't clear the echo area if there's no
4586 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4587 contents of *Minibuf-0*) if there's no message displayed in its stead.
4589 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4591 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4594 2012-05-06 Chong Yidong <cyd@gnu.org>
4596 * lisp.mk (lisp): Update.
4598 2012-05-05 Jim Meyering <meyering@redhat.com>
4600 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4602 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4604 * data.c (PUT_ERROR): New macro.
4605 (syms_of_data): Use it. Add new error type `user-error'.
4606 * undo.c (user_error): New function.
4607 (Fprimitive_undo): Use it.
4608 * print.c (print_error_message): Adjust print style for `user-error'.
4609 * keyboard.c (user_error): New function.
4610 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4612 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4614 Do not limit current-time-string to years 1000..9999.
4615 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4616 (Fcurrent_time_string): Support any year that is supported by the
4617 underlying localtime representation. Don't use asctime, as it
4618 has undefined behavior for years outside the range -999..9999.
4620 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4622 Fix race conditions involving setenv, gmtime, localtime, asctime.
4623 Without this fix, interrupts could mess up code that uses these
4624 nonreentrant functions, since setting TZ invalidates existing
4625 tm_zone or tzname values, and since most of these functions return
4626 pointers to static storage.
4627 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4628 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4629 Grow the critical sections to include not just invoking
4630 localtime/gmtime, but also accessing these functions' results
4631 including their tm_zone values if any, and any related TZ setting.
4632 (format_time_string): Last arg is now struct tm *, not struct tm **,
4633 so that the struct tm is saved in the critical section.
4634 All callers changed. Simplify allocation of initial buffer, partly
4635 motivated by the fact that memory allocation needs to be outside
4636 the critical section.
4638 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4640 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4641 with RESET_INTERVAL.
4643 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4644 Remove duplicated buffer name initialization.
4646 2012-05-02 Jim Meyering <jim@meyering.net>
4648 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4650 * xfns.c (x_window): Use xstrdup (Bug#11375).
4652 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4654 * xdisp.c (pos_visible_p): If already at a newline from the
4655 display string before the 'while' loop, don't walk back the glyphs
4656 from it3.glyph_row. Solves assertion violation when the display
4657 string begins with a newline (egg.el). (Bug#11367)
4659 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4661 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4664 2012-05-01 Glenn Morris <rgm@gnu.org>
4666 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4667 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4668 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4669 All were removed before 23.1.
4671 * dispnew.c: Remove HAVE_LIBNCURSES test;
4672 it is always true on relevant platforms.
4674 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4675 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4677 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4679 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4681 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4682 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4685 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4687 Do not avoid creating empty evaporating overlays (Bug#9642).
4688 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4689 That is, do not delete an evaporating overlay if it becomes
4690 empty after its bounds are adjusted to fit within its buffer.
4691 This fix caused other problems, and I'm reverting it until we get
4692 to the bottom of them.
4694 2012-04-27 Chong Yidong <cyd@gnu.org>
4696 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4698 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4700 * xdisp.c (pos_visible_p): If the window start position is beyond
4701 ZV, start the display from buffer beginning. Prevents assertion
4702 violation in init_iterator when the minibuffer window is scrolled
4705 * window.c (window_scroll_pixel_based): Likewise.
4707 2012-04-27 Chong Yidong <cyd@gnu.org>
4709 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4711 2012-04-27 Glenn Morris <rgm@gnu.org>
4713 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4714 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4716 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4718 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4719 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4721 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4723 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4724 display element, check also the underlying string or buffer
4725 character. (Bug#11341)
4727 * w32menu.c: Include w32heap.h.
4728 (add_menu_item): If the call to AppendMenuW (via
4729 unicode_append_menu) fails, disable Unicode menus only if we are
4730 running on Windows 9X/Me.
4732 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4734 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4735 (xgetint): Add missing shift for LSB tags.
4737 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4739 * keyboard.c (read_char): Don't wipe echo area for select window
4740 events: These might get delayed via `mouse-autoselect-window'
4743 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4745 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4746 manipulation of :loaded-from data.
4748 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4750 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4751 now a cons (bug#11311).
4753 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4755 Do not create empty overlays with the evaporate property (Bug#9642).
4756 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4757 if it becomes empty after its bounds are adjusted to fit within
4758 its buffer. Without this fix, in a nonempty buffer (let ((o
4759 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4760 yields an empty overlay that has the evaporate property, which is
4761 not supposed to happen.
4763 Fix minor GTK3 problems found by static checking.
4764 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4765 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4766 (struct _EmacsFixedClass, emacs_fixed_get_type):
4767 Move decls here from emacsgtkfixed.h, since they needn't be public.
4768 (emacs_fixed_get_type): Now static.
4769 (emacs_fixed_class_init): Omit unused local.
4770 (emacs_fixed_child_type): Remove; unused.

4773 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4774 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4775 (EMACS_FIXED_GET_CLASS): Remove; unused.
4776 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4778 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4779 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4781 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4783 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4784 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4785 (__malloc_size_t, __malloc_ptrdiff_t):
4786 Remove. All uses removed, replaced by the definiens if needed,
4787 since we can assume C89 or better now.
4788 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4789 (protect_malloc_state, align, get_contiguous_space)
4790 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4796 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4797 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4798 Define using prototypes, not old style.
4799 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4800 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4801 (align): Don't assume that signed integer overflow wraps around.
4802 Omit unused local var.
4803 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
4804 (_free_internal_nolock, memalign, mallochook, reallochook):
4805 Omit no-longer-needed casts.
4806 (valloc): Use getpagesize, not __getpagesize.
4807 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
4808 (struct hdr): The 'magic' member is now size_t, not unsigned long.
4810 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
4812 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
4814 Move functions from C to Lisp. Make non-blocking method calls
4815 the default. Implement further D-Bus standard interfaces.
4817 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
4818 (QCdbus_request_name_allow_replacement)
4819 (QCdbus_request_name_replace_existing)

4857 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4859 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
4860 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
4861 Do not assume ptrdiff_t is the same width as 'int'.
4863 * alloc.c: Handle unusual debugging option combinations.
4864 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4865 since the two debugging options are incompatible.
4866 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4868 (mem_init, mem_insert, mem_insert_fixup):
4869 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
4870 (NEED_MEM_INSERT): Remove; no longer needed.
4872 2012-04-22 Leo Liu <sdl.web@gmail.com>

4899 * print.c (print_preprocess): Only check print_depth if print-circle
4901 (print_object): Check for cycles even when print-circle is nil and
4902 print-gensym is t, but only check print_depth if print-circle is nil.
4904 2012-04-20 Chong Yidong <cyd@gnu.org>
4906 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4907 set the status to "failed" and ensure that sentinel is run.
4909 2012-04-20 Glenn Morris <rgm@gnu.org>

4920 row, return zero immediately.
4921 (try_cursor_movement): If inside continuation line, don't back up
4922 farther than the first row after the header line, if any.
4923 Don't consider the header-line row as "partially visible", even if
4924 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
4926 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4961 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
4962 New extern decls, to avoid calling undeclared functions.
4963 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4964 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4965 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4966 (NEED_MEM_INSERT): New macro.
4967 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4968 Remove one incorrect comment and fix another.

4982 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4983 Remove decls. This fixes an "It stinks!".

4987 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4989 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5002 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5003 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5004 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5005 * s/netbsd.h, s/sol2-6.h:
5006 Remove definition of GC_MARK_STACK, since the default now works.
5007 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5008 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5009 no longer the default.
5010 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5012 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5014 * lread.c (lisp_file_lexically_bound_p):

5035 2012-04-11 Daniel Colascione <dancol@dancol.org>
5037 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5038 against is gone. It's better to use vfork now so that when Cygwin
5039 gains a new, working vfork, we use it automatically (bug#10398).
5041 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5057 (handle_interrupt): Use it.
5059 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5061 * w32.c (w32_delayed_load): Record the full path of the library
5062 being loaded (bug#10424).
5064 2012-04-09 Glenn Morris <rgm@gnu.org>
5066 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5067 not just in the obarray, before snarfing them. (Bug#11036)
5069 * Makefile.in ($(leimdir)/leim-list.el):
5070 Pass EMACS rather than BUILT_EMACS.

5079 Add convenience `GNUTLS_LOG2i' macro.
5081 * gnutls.c (gnutls_log_function2i): Convenience log function.
5082 (emacs_gnutls_read): Use new log functions,
5083 `gnutls_handshakes_tried' process member, and

5085 attempts per process (connection).
5087 2012-04-09 Chong Yidong <cyd@gnu.org>
5089 * eval.c (Fuser_variable_p, user_variable_p_eh)

5094 * minibuf.c (Fread_variable): Callers changed.
5096 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5098 * xdisp.c (set_cursor_from_row): If the display string appears in
5099 the buffer at position that is closer to point than the position
5100 after the display string, display the cursor on the first glyph of
5101 the display string. Fixes cursor display when a 'display' text
5102 property immediately follows invisible text. (Bug#11094)
5104 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5106 composite.c: use 'double' consistently
5107 * composite.c (get_composition_id): Use 'double' consistently
5108 instead of converting 'float' to 'double' and vice versa; this is
5109 easier to understand and avoids a GCC warning.
5111 2012-04-09 Glenn Morris <rgm@gnu.org>
5113 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5114 preparation for dumping it with emacs. (Bug#4789)

5136 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5137 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5138 objects, as mark_maybe_pointer will catch them otherwise.
5139 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5140 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

5144 Fix typo that broke non-Windows builds.
5145 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5156 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5157 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5158 [!WINDOWSNT]: New macros.
5159 (init_libxml2_functions, libxml2_loaded_p): New functions.
5160 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5161 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5162 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5163 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5165 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5166 Call init_libxml2_functions before calling libxml2 functions.
5167 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5169 * emacs.c: Don't include libxml/parser.h.
5170 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5171 xmlCleanupParser directly.
5173 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5175 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5177 * indent.c (Fvertical_motion): If there is a display string at
5178 point, use it.vpos to compute how many lines to backtrack after

5181 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5183 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5184 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5185 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5186 macros related to unification of CJK characters. For the details,
5187 see the discussion following the message here:
5188 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5190 2012-04-04 Chong Yidong <cyd@gnu.org>
5192 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5194 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5196 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

5204 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5206 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5207 position we get to after a call to move_it_to fails the
5208 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5209 only if we wind up in a string from display property. (Bug#11063)
5211 * window.c (Fdelete_other_windows_internal): Invalidate the row
5212 and column information about mouse highlight, so that redisplay
5213 restores it after reallocating the glyph matrices. (Bug#7464)
5215 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5216 string comes from a `display' text property, use the buffer
5217 position of that property as if we actually saw that position in
5219 (move_it_by_lines): Remove the assertion that
5220 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5221 violated when there's a before-string at the beginning of a line.
5224 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5226 * xdisp.c (append_space_for_newline): If the default face was
5227 remapped, use the remapped face for the appended newline.
5228 (extend_face_to_end_of_line): Use the remapped default face for
5229 extending the face to the end of the line.
5230 (display_line): Call extend_face_to_end_of_line when the default
5231 face was remapped. (Bug#11068)
5233 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5235 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

5255 handle-select-window too (Bug#8996).
5257 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5259 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5261 2012-03-25 Kenichi Handa <handa@m17n.org>
5263 * dispextern.h (struct glyph): Change the bit length of
5264 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5266 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5268 * s/ms-w32.h (tzname): Include time.h before redirecting to
5269 _tzname. Fixes the MSVC build. (Bug#9960)
5271 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5273 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5276 * xterm.c (XTread_socket): Only modify handling_signal if
5277 !SYNC_INPUT. (Bug#11080)
5279 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5281 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5282 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5283 when fetching a multibyte character consumes more bytes than
5284 CHAR_BYTES returns, due to unification of CJK characters in
5285 string_char. (Bug#11073)
5287 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5289 * process.c (wait_reading_process_output): Handle pty disconnect
5290 by refraining from sending oneself a SIGCHLD (bug#10933).

5301 2012-03-21 Chong Yidong <cyd@gnu.org>
5303 * xfaces.c (Vface_remapping_alist): Doc fix.
5305 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5307 * w32proc.c (Fw32_set_console_codepage)
5308 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

5319 it fit in a valid range (Bug#11003).
5321 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5323 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5324 that is not from display property, accept the row as a "cursor
5325 row" if one of the string's character has a non-nil `cursor'
5326 property. Fixes cursor positioning when there are newlines in
5327 overlay strings, e.g. in icomplete.el. (Bug#11035)
5329 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5331 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5333 2012-03-12 Chong Yidong <cyd@gnu.org>
5335 * eval.c (inhibit_lisp_code): Rename from
5336 inhibit_window_configuration_change_hook; move from window.c.
5338 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5339 * window.c (run_window_configuration_change_hook)
5340 (syms_of_window): Callers changed.

5360 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5363 2012-03-03 Glenn Morris <rgm@gnu.org>

5378 * buffer.c (buffer-list-update-hook): Doc fix.
5380 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5383 push_it before setting up the iterator for the first overlay
5384 string, even if we have an empty string loaded.
5385 (next_overlay_string): If there's an empty string on the iterator
5386 stack, pop the stack. (Bug#10903)
5388 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5390 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5391 Suggested by Stefan Monnier in
5392 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5393 * alloc.c (widen_to_Lisp_Object): New static function.
5394 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5395 and widening them to Lisp_Objects. This would work even if
5396 USE_LSB_TAG is defined and wide integers are used, which might
5397 happen in a future version of Emacs.
5399 2012-02-25 Chong Yidong <cyd@gnu.org>
5401 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

5438 when computing $valmask.
5440 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5441 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5442 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5443 It's useless in that case, and it can cause problems on hosts
5444 that allocate halves of EMACS_INT values separately.
5445 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5446 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5447 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5448 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5449 it avoids undefined behavior on hosts where shifting right by more
5450 than the word width has undefined behavior.
5452 2012-02-19 Chong Yidong <cyd@gnu.org>
5454 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5455 (Funhandled_file_name_directory, Ffile_name_as_directory)

5474 2012-02-15 Chong Yidong <cyd@gnu.org>
5476 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5477 marked as special. Also, starting docstrings with * is obsolete.

5495 as that creates a dangerous corner case.
5497 * window.c (Fdelete_window_internal): Invalidate the mouse
5498 highlight (Bug#9904).
5500 2012-02-12 Glenn Morris <rgm@gnu.org>

5530 2012-02-07 Chong Yidong <cyd@gnu.org>
5532 * buffer.c (Fbuffer_local_variables)
5533 (buffer_lisp_local_variables): Handle unbound vars correctly;
5534 don't let Qunbound leak into Lisp.
5536 2012-02-07 Glenn Morris <rgm@gnu.org>
5538 * image.c (Fimagemagick_types): Doc fix.
5540 * image.c (imagemagick-render-type): Change it from a lisp object

5573 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5575 Handle overflow when computing char display width (Bug#9496).
5576 * character.c (char_width): Return EMACS_INT, not int.
5577 (char_width, c_string_width): Check for overflow when
5578 computing the width; this is possible now that individual
5579 characters can have unbounded width. Problem introduced
5580 by merge from Emacs 23 on 2012-01-19.
5582 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6234 is set, removing the need for VIRT_ADDRESS_VARIES.

6238 to 4 (xorl, subq, cmpq, setbe).
6239 * alloc.c (pure): Always extern now, since that's the

6252 behave as if the cursor position were at the window margin.
6254 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6255 and the cursor position is out of bounds, behave as if the cursor

6286 * dispnew.c (verify_row_hash): Call row_hash for computing the
6287 hash code of a row, instead of duplicating code from xdisp.c.
6289 * dispextern.h (row_hash): Add prototype.
6291 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6293 * frame.c (delete_frame): Don't delete the terminal when the last

6321 occurrences of window_nest to window_combination_limit.
6323 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6325 * image.c (imagemagick_load_image): Fix typo.
6327 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6329 * xdisp.c (display_line): Move the call to
6330 highlight_trailing_whitespace before the call to

6397 The trivial performance wins aren't worth the portability hassles; see
6398 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6400 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6477 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6478 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6479 * intervals.c (adjust_intervals_for_insertion)
6480 (adjust_intervals_for_deletion): Now extern, because otherwise the
6481 extern inline functions 'offset_intervals' couldn't refer to it.
6482 (static_offset_intervals): Remove.
6483 (offset_intervals): Rewrite using the old contents of
6484 static_offset_intervals. The old version didn't conform to C99
6485 because an extern inline function contained a reference to an

6508 (Fwindow_vscroll): Doc fix.
6509 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default

6801 This fixes a bug when the time zone name contains characters that
6802 need converting from the system time locale to Emacs internal format.
6803 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6804 that patch fixed format-time-string to do the conversion, but
6805 I forgot to fix current-time-zone.
6806 (format_time_string): New function, containing most of
6807 what Fformat_time_string used to contain.
6808 (Fformat_time_string): Rewrite in terms of format_time_string.
6809 This doesn't change this function's behavior.
6810 (current-time-zone): Rewrite to use format_time_string.
6811 This fixes the bug reported by Michael Schierl in
6812 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6813 Jason Rumney's 2007-06-07 change worked around this bug, but
6815 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6817 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6819 * xdisp.c (start_display): If the character at POS is displayed
6820 via a display vector, reset IT->current.dpvec_index to zero.
6821 (try_window_reusing_current_matrix): If a line ends in a display
6822 vector or the next line starts in a display vector, continue
6823 redrawing the window even though the character position of
6824 start_row was reached.
6827 2011-10-18 Chong Yidong <cyd@gnu.org>
6829 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6830 with nobreak-char-display too.
6832 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6834 Fix part 3 of bug#9771.
6835 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6836 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6837 non-neutral characters if the current character is a paragraph
6838 separator (a.k.a. Newline). This avoids running the same
6839 expensive loop twice, once when we consume the preceding newline
6840 and the other time when the line actually needs to be displayed.
6841 Avoid the loop when we see neutrals on the base embedding level
6842 following a character whose directionality is the same as the
6843 paragraph's. This avoids running the expensive loop when a line
6844 ends in a long sequence of neutrals, like control characters.
6845 Add assertion against STRONG_AL type. Slightly rearrange code
6846 that determines the type of a neutral given the first non-neutral
6848 (bidi_level_of_next_char): Set next_en_pos to zero when
6849 invalidating its info.
6851 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6853 * xdisp.c (push_display_prop): Determine whether to record string
6854 or buffer position by IT->string, not by IT->method. Allow
6855 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6856 (move_it_vertically_backward): Don't look for character position
6857 immediately after the newline when in a continuation line.
6860 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6862 * window.c (coordinates_in_window): Rewrite and delabelize
6863 vertical border check. (Bug#5357) (Bug#9618)
6865 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6867 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6868 errors in XSetWindowBorder (bug#9310).
6870 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6872 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6873 avoid crash when xmalloc overrun checking is enabled.
6875 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6877 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6878 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6879 cursor motion with <left> and <right> arrow keys.
6881 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6882 some callers set that themselves.
6884 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6886 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6887 display string and the previous row comes from the same string and
6888 is empty. (Bug#9739) (Bug#9738)
6890 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6892 * doc.c (get_doc_string): Encode file name (bug#9735).
6894 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6896 * bidi.c (bidi_level_of_next_char):
6897 * xdisp.c (get_visually_first_element): Remove old incorrect
6898 comments regarding the Unicode Line Separator character.
6900 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6902 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6904 * alloc.c (Fgc_status): Do not access beyond zombies array
6905 boundary if nzombies > MAX_ZOMBIES.
6906 * alloc.c (dump_zombies): Add missing format specifier.
6908 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6910 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6911 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6913 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6914 Some packages use them to denote characters with modifiers.
6916 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6918 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6919 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6920 matching a pp-number. Rename parameter var to var1.
6922 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6924 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6926 2011-10-08 Glenn Morris <rgm@gnu.org>
6928 * callint.c (Fcall_interactively): Give a more explicit error for the
6929 'c' case with a non-character input. (Bug#8479)
6931 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6933 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6935 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6936 lines that are hscrolled on the left.
6938 * dispnew.c (buffer_posn_from_coords): Account for a possible
6939 presence of header-line. (Bug#4426)
6941 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6943 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6944 Don't advertise functionality which we discourage or doesn't work.
6946 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6948 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6949 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6950 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6951 this makes Emacs dump core during garbage collection on rare
6952 occasions. sizeof is obviously inferior to offsetof here, so
6953 stick with offsetof.
6954 (GC_POINTER_ALIGNMENT): New macro.
6955 (mark_memory): Omit 3rd (offset) arg; caller changed.
6956 Don't assume EMACS_INT alignment is the same as pointer alignment.
6958 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6960 * keyboard.c (read_key_sequence_remapped): New var.
6961 (read_key_sequence): Compute remapping in the right buffer.
6962 (command_loop_1): Use read_key_sequence's remapping directly.
6964 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6966 * dired.c (file_name_completion): Don't expand file name.
6967 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6968 before checking file name handler.
6970 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6971 they've been requested explicitly (bug#9591).
6973 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6975 * keymap.c (Fsingle_key_description): Use make_specified_string
6976 instead of build_string to build string from push_key_description.
6979 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6981 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6982 This fixes a Y2038 bug on 64-bit hosts.
6983 * buffer.c (reset_buffer):
6984 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6985 (Fclear_buffer_auto_save_failure):
6986 Use 0, not -1, to represent an unset failure time, since time_t
6987 might not be signed.
6989 Remove dependency on glibc malloc internals.
6990 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6991 Move back here from lisp.h, but with their new implementations.
6992 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6993 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6994 * charset.c (charset_table_init): New static var.
6995 (syms_of_charset): Use it instead of xmalloc. This removes a
6996 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6997 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6998 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6999 Move back to alloc.c.
7000 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7001 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7003 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7005 * nsterm.m (windowDidResize): Call x_set_window_size only when
7006 ns_in_resize is true. Otherwise set pixelwidth/height and
7007 call change_frame_size (Bug#9628).
7009 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7011 Port --enable-checking=all to Fedora 14 x86-64.
7012 * charset.c (syms_of_charset): Also account for glibc malloc's
7013 internal overhead when calculating the initial malloc maximum.
7015 Port --enable-checking=all to Fedora 14 x86.
7016 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7018 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7019 (overrun_check_realloc, overrun_check_free):
7020 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7021 That way, xmalloc returns a properly-aligned pointer even if
7022 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7023 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7024 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7025 into account when calculating the initial malloc maximum.
7026 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7027 Move here from alloc.c, so that charset.c can use it too.
7028 Properly align; the old code wasn't right for common 32-bit hosts
7029 when configured with --enable-checking=all.
7030 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7031 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7033 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7035 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7038 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7040 * xdisp.c (compute_display_string_end): If there's no display
7041 string at CHARPOS, return -1.
7043 * bidi.c (bidi_fetch_char): When compute_display_string_end
7044 returns a negative value, treat the character as a normal
7045 character not covered by a display string. (Bug#9624)
7047 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7049 * lread.c (Fread_from_string): Fix typo in docstring.
7051 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7053 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7054 newline, reseat the iterator instead of bidi-iterating there one
7055 character at a time. (Bug#9610)
7056 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7057 TO_CHARPOS if the bidi iterator is at base embedding level.
7059 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7061 * lread.c (readevalloop): Use correct code for NBSP.
7062 (read1): Likewise. (Bug#9608)
7064 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7066 * dbusbind.c (Fdbus_register_signal): When service is not
7067 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7069 2011-09-25 Glenn Morris <rgm@gnu.org>
7071 * buffer.c (truncate-lines): Doc fix.
7073 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7075 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7076 (Fset_window_next_buffers): Doc fix.
7078 2011-09-24 Glenn Morris <rgm@gnu.org>
7080 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7082 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7084 Fix minor problems found by static checking.
7085 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7086 * indent.c (Fvertical_motion): Fix == vs = typo.
7088 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7090 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7091 Default value is now t. Doc fix.
7093 * indent.c (Fvertical_motion): Compute and apply the overshoot
7094 logic when moving up, not only when moving down. Fix the
7095 confusing name and values of the it_overshoot_expected variable;
7096 logic changes accordingly. (Bug#9254) (Bug#9549)
7098 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7099 CHARPOS is covered by a display string which includes newlines.
7100 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7101 is covered by a display string with embedded newlines.
7103 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7105 * dbusbind.c (Fdbus_register_signal): Add match rule to
7106 Vdbus_registered_objects_table. (Bug#9581)
7107 (Fdbus_register_method, Vdbus_registered_objects_table):
7110 2011-09-24 Jim Meyering <meyering@redhat.com>
7112 do not ignore write error for any output size
7113 The previous change was incomplete.
7114 While it makes emacs --batch detect the vast majority of stdout
7115 write failures, errors were still ignored whenever the output size is
7116 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7117 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7118 && echo FAIL: ignored write error
7119 FAIL: ignored write error
7120 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7121 && echo FAIL: ignored write error
7122 FAIL: ignored write error
7123 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7125 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7127 * emacs.c (Fkill_emacs): In noninteractive mode exit
7128 non-successfully if a write error occurred on stdout. (Bug#9574)
7130 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7132 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7135 * dispextern.h (struct it): Update the comment documenting what
7138 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7140 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7141 a display string, extend search for cursor position to end of row.
7142 (find_row_edges): If the row ends in a newline from a display
7143 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7144 Handle the case of a display string with multiple newlines.
7145 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7146 non-empty line. Fixes confusing cursor motion with arrow keys at
7147 the beginning of a line that starts with whitespace.

7151 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7154 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7156 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7159 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7161 * xdisp.c (display_line): Record maximum and minimum buffer
7162 positions even if no glyphs were produced (e.g., by a zero-width
7163 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7164 buffer positions that will be removed from the glyph row because
7166 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7167 column is beyond frame width: don't subtract 1 "pixel" when
7168 computing width of the stretch.
7169 (reseat_at_next_visible_line_start): Undo the change made on
7170 2011-09-17 that saved paragraph information and restored it after
7171 the call to `reseat'. (Bug#9545)
7173 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7175 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7176 and turn window cursor on if cleared (Bug#9415).

7187 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7189 Fix minor problem found by static checking.
7190 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7191 initialized, to pacify gcc -Wuninitialized.
7193 * fileio.c: Report proper errno when syscall falls.
7194 (Finsert_file_contents): Save and restore errno,
7195 so that report_file_error outputs the correct diagnostic.
7196 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7198 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7200 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7202 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7204 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7205 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7207 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7209 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7210 about the current paragraph and restore it after the call to reseat.
7212 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7213 (bidi_find_paragraph_start): Search back for paragraph beginning
7214 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7215 (bidi_move_to_visually_next): Only trigger paragraph-related
7216 computations when the last character is a newline or at EOB, not
7217 just any NEUTRAL_B. (Bug#9470)
7219 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7220 truncated lines if point is covered by a display string. (Bug#9524)
7222 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7224 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7225 (cons_to_x_long): New function.
7226 (lisp_data_to_selection_data): Use it. Correct the test for
7227 short-versus-long data; it was negated. Break out of vector
7228 loop, for efficiency, when a long datum is discovered.
7230 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7232 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7234 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7236 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7237 GCC PR/17406) by declaring this function with external scope.
7239 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

7260 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7261 This occurs when processing a multibyte format.
7262 Problem reported by Wolfgang Jenker.
7264 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7266 * xdisp.c (try_cursor_movement): Only check for exact match if
7267 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7269 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7271 Remove unused external symbols.
7272 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7273 * xdisp.c (calc_pixel_width_or_height): Now static.
7274 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7275 * indent.c (check_display_width):
7276 * w32term.c: Fix comment to match code.
7277 * xterm.c, xterm.h (x_catching_errors): Remove.
7279 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7281 * xselect.c: Use signed conversions more consistently (Bug#9498).
7282 (selection_data_to_lisp_data): Assume incoming selection data are
7283 signed integers, not unsigned. This is to be consistent with
7284 outgoing selection data, which was modified to use signed integers
7285 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7286 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7287 expects long, not unsigned long.
7289 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7291 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7292 computation of loop end. Reported by Johan Bockgård
7295 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7297 * frame.c (Fother_visible_frames_p): Function deleted.
7299 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7301 * indent.c (compute_motion): Process display vector front to back
7302 rather than the other way around. (Bug#2496)
7304 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7306 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7308 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7310 * minibuf.c (Fread_from_minibuffer): Doc fix.
7312 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7314 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7315 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7317 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7319 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7320 value for non-existent files.
7322 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7324 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7325 set its "size" to -1. This will set the modtime_size field of
7326 the corresponding buffer to -1, which is what
7327 verify-visited-file-modtime expects for files that do not exist.
7330 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7332 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7334 * lisp.h: ... from here. push_key_description is no longer
7335 defined in keyboard.c, so its declaration should not be in
7336 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7337 logically belongs with push_key_description.
7339 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7341 * buffer.h: Include <sys/types.h> instead of <time.h>.
7342 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7343 Problem reported by Herbert J. Skuhra.
7345 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7347 * xml.c (parse_region): Make the parsing work for
7348 non-comment-starting XML files again (bug#9144).
7350 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7352 * image.c (gif_load): Fix calculation of bottom and right corner.
7355 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7357 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7358 redisplay in small windows.
7360 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7362 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7364 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7366 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7367 Operate on live windows only.
7369 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7371 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7373 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7375 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7376 only under bidi iteration.
7378 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7380 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7382 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7384 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7385 Without this fix, the command to link temacs failed due to an
7386 undefined symbol __builtin_isnan. This is because
7387 /usr/include/iso/math_c99.h #defines isnan(x) to
7388 __builtin_isnan(x), but the bundled gcc, which identifies itself
7389 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7391 * floatfns.c (isnan): #undef, and then #define to a clone of
7393 (Fisnan): Always define, since it's always available now.
7394 (syms_of_floatfns): Always define isnan at the Lisp level.
7396 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7398 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7400 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7402 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7403 The previous code assumed that file offsets (off_t values) fit in
7404 EMACS_INT variables, which is not true on typical 32-bit hosts.
7405 The code messed up by falsely reporting buffer overflow in cases
7406 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7407 when "big" contains more than 2**29 bytes, even though this
7408 inserts just one byte and does not overflow the buffer.
7409 (Finsert_file_contents): Store file offsets as off_t
7410 values, not as EMACS_INT values. Check for overflow when
7411 converting between EMACS_INT and off_t. When checking for
7412 buffer overflow or for overlap, take the offsets into account.
7413 Don't use EMACS_INT for small values where int suffices.
7414 When checking for overlap, fix a typo: ZV was used where
7415 ZV_BYTE was intended.
7416 (Fwrite_region): Don't assume off_t fits into 'long'.
7417 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7419 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7421 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7423 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7425 sprintf-related integer and memory overflow issues (Bug#9412).
7427 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7428 (esprintf, exprintf, evxprintf): New functions.
7429 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7430 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7431 (modify_event_symbol): Do not assume that the length of
7432 name_alist_or_stem is safe to alloca and fits in int.
7433 (Fexecute_extended_command): Likewise for function name and binding.
7434 (Frecursion_depth): Wrap around reliably on integer overflow.
7435 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7436 since some callers pass EMACS_INT values.
7437 (Fsingle_key_description): Don't crash if symbol name contains more
7438 than MAX_ALLOCA bytes.
7439 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7440 (get_minibuffer): Arg is now EMACS_INT, not int.
7441 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7442 (esprintf, exprintf, evxprintf): New decls.
7443 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7445 * dbusbind.c (signature_cat): New function.
7446 (xd_signature, Fdbus_register_signal):
7447 Do not overrun buffer; instead, report string overflow.
7449 * dispnew.c (add_window_display_history): Don't overrun buffer.
7450 Truncate instead; this is OK since it's just a log.
7452 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7453 even if the time zone offset is outlandishly large.
7454 Don't mishandle offset == INT_MIN.
7456 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7457 when creating daemon; the previous buffer-overflow check was incorrect.
7459 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7460 which has the guts of the old verror function.
7462 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7463 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7465 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7466 (font_unparse_xlfd): Don't blindly alloca long strings.
7467 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7468 fits in int, when using sprintf. Use single snprintf to count
7469 length of string rather than counting it via multiple sprintfs;
7470 that's simpler and more reliable.
7471 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7472 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7473 sprintf, in case result does not fit in int.
7475 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7476 (fontset_from_font): Print it.
7478 * frame.c (tty_frame_count): Now printmax_t, not int.
7479 (make_terminal_frame, set_term_frame_name): Print it.
7480 (x_report_frame_params): In X, window IDs are unsigned long,
7481 not signed long, so print them as unsigned.
7482 (validate_x_resource_name): Check for implausibly long names,
7483 and don't assume name length fits in 'int'.
7484 (x_get_resource_string): Don't blindly alloca invocation name;
7485 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7488 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7489 (xg_check_special_colors, xg_set_geometry):
7490 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7492 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7493 Use esprintf, not sprintf, in case result does not fit in int.
7495 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7496 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7497 it as a large positive number.
7498 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7499 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7501 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7502 in case result does not fit in int.
7504 * print.c (float_to_string): Detect width overflow more reliably.
7505 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7506 buffer overrun. Don't assume list length fits in 'int'. Treat
7507 print length of 0 as 0, not as infinity; to be consistent with other
7508 uses of print length in this function. Don't overflow print length
7509 index. Don't assume hash table size fits in 'long', or that
7510 vectorlike size fits in 'unsigned long'.
7512 * process.c (make_process): Use printmax_t, not int, to format
7513 process-name gensyms.
7515 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7517 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7518 to avoid potential buffer overrun.
7520 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7521 if X resource line is longer than 512 bytes.
7523 * xfns.c (x_window): Make sprintf buffer a bit bigger
7524 to avoid potential buffer overrun.
7526 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7528 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7530 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7532 Integer overflow fixes for scrolling, etc.
7533 Without these, Emacs silently mishandles large integers sometimes.
7534 For example, "C-u 4294967297 M-x recenter" was treated as if
7535 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7537 * xdisp.c (try_window_id): Check Emacs fixnum range before
7538 converting to 'int'.
7540 * window.c (window_scroll_line_based, Frecenter):
7541 Check that an Emacs fixnum is in range before assigning it to 'int'.
7542 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7543 values converted from Emacs fixnums.
7544 (Frecenter): Don't wrap around a line count if it is out of 'int'
7545 range; instead, treat it as an extreme value.
7546 (Fset_window_configuration, compare_window_configurations):
7547 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7549 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7550 that can exceed INT_MAX. Check that EMACS_INT value is in range
7551 before assigning it to the (possibly-narrower) index.
7552 (match_limit): Don't assume that a fixnum can fit in 'int'.
7554 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7557 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7558 (Fvertical_motion): Don't wrap around LINES values that don't fit
7559 in 'int'. Instead, treat them as extreme values. This is good
7560 enough for windows, which can't have more than INT_MAX lines anyway.
7562 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7564 * Require libxml/parser.h to avoid compilation warning.
7566 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7568 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7569 since this reportedly can destroy thread storage.
7571 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7573 * syntax.c (find_defun_start): Update all cache variables if
7574 exiting early (Bug#9401).
7576 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7578 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7580 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7581 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7582 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7584 * term.c (tty_append_glyph): New function.
7585 (produce_stretch_glyph): Static function and its prototype deleted.
7587 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7590 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7592 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7593 when checking :margin (Bug#9390).
7594 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7595 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7596 so that the name doesn't mislead. All uses changed.
7598 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7600 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7603 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7605 * xdisp.c (move_it_to): Don't bail out early when reaching
7606 position beyond to_charpos, if we are scanning backwards.
7607 (move_it_vertically_backward): When DY == 0, make sure we get to
7608 the first character in the line after the newline.
7610 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7612 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7613 (ccl_driver): Do not generate an out-of-range pointer.
7614 (Fccl_execute_on_string): Remove unnecessary check for
7615 integer overflow, noted by Stefan Monnier in
7616 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7617 Remove a FIXME that didn't need fixing.
7618 Simplify the newly-introduced buffer reallocation code.
7620 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7622 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7624 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7626 Integer and memory overflow issues (Bug#9196).
7628 * doc.c (get_doc_string): Rework so that
7629 get_doc_string_buffer_size is the actual buffer size, rather than
7630 being 1 less than the actual buffer size; this makes xpalloc more
7633 * image.c (x_allocate_bitmap_record, cache_image):
7634 * xselect.c (Fx_register_dnd_atom):
7635 Simplify previous changes by using xpalloc.
7637 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7638 since either will do and ptrdiff_t is convenient with xpalloc.
7640 * charset.c (charset_table_size)
7641 (struct charset_sort_data.priority): Now ptrdiff_t.
7642 (charset_compare): Don't overflow if priorities differ greatly.
7643 (Fsort_charsets): Don't assume list length fits in int.
7644 Check for size-calculation overflow when allocating sort data.
7645 (syms_of_charset): Allocate an initial charset table that is
7646 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7648 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7650 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7651 The actual value is always <= INT_MAX, and leaving it unsigned made
7652 overflow checking harder.
7654 * dispextern.h (struct glyph_matrix.rows_allocated)
7655 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7656 with xpalloc. The values are still always <= INT_MAX.
7658 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7660 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7661 (SAFE_NALLOCA): New macro.
7663 * region-cache.c (struct boundary.pos, find_cache_boundary)
7664 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7665 (set_cache_region, invalidate_region_cache)
7666 (revalidate_region_cache, know_region_cache, region_cache_forward)
7667 (region_cache_backward, pp_cache):
7668 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7669 so that ptrdiff_t * can be passed to xpalloc.
7670 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7671 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7672 (pp_cache): Don't assume cache_len fits in int.
7673 * region-cache.h: Adjust extern decls to match.
7675 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7676 EMACS_INT, since either will do, for xpalloc.
7678 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7679 (xnmalloc, xnrealloc, xpalloc): New functions.
7681 * bidi.c (bidi_shelve_header_size): New constant.
7682 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7683 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7685 * bidi.c (bidi_cache_shrink):
7686 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7688 Don't update size of array until after memory allocation succeeds,
7689 because xmalloc/xrealloc may not return.
7690 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7691 now that we have proper integer overflow checking.
7692 (record_overlay_string, overlay_strings): Catch overflows when
7693 calculating size of overlay_str_buf.
7695 * callproc.c (Fcall_process): Check for size overflow when
7696 calculating size of args2.
7697 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7698 Normally we prefer signed values, but sticking with ptrdiff_t would
7699 require adding more-complicated checks.
7701 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7702 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7703 Redo buffer-overflow calculations to avoid integer overflow.
7704 Add a FIXME comment where memory seems to be over-allocated.
7706 * character.c (Fstring): Check for size-calculation overflow.
7708 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7709 unnecessary integer overflow. Check for size overflow.
7710 (encode_coding_object): Don't update size until xmalloc succeeds.
7712 * composite.c (get_composition_id): Check for overflow in glyph
7713 length calculations.
7715 Integer and memory overflow fixes for display code.
7716 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7717 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7718 (scrolling_window): Check for overflow in size calculations.
7719 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7720 Don't assume glyph table len fits in int.
7721 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
7722 (row_table_size): Now ptrdiff_t, not int.
7723 (scrolling_window): Avoid overflow in size calculations.
7724 Don't update size until allocation succeeds.
7725 * fns.c (concat): Check for overflow in size calculations.
7726 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
7727 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7728 (NEXT_ALMOST_PRIME_LIMIT): New constant.
7730 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7731 (get_doc_string): Check for size calculation overflow.
7732 Don't update size until allocation succeeds.
7733 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7734 EMACS_INT, where ptrdiff_t will do.
7735 (Fsubstitute_command_keys): Check for string overflow.
7737 * editfns.c (set_time_zone_rule): Don't assume environment length
7739 (message_length): Now ptrdiff_t, not int.
7740 (Fmessage_box): Don't update size until allocation succeeds.
7741 Don't assume message length fits in int.
7742 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7744 * emacs.c (main): Do not reallocate argv, since there is a null at
7745 the end that can be overwritten, and this way there's no need to

7876 (X_LONG_MIN): New macros.
7877 Use them to make the following changes clearer.
7878 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

7880 future maintainers not to raise the value too much later.
7881 (SELECTION_QUANTUM): Remove, replacing with ...
7882 (selection_quantum): ... new function, which avoids overflow.
7884 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

7904 Don't double-block input; malloc is safe here. Don't assume 2**34
7905 - 4 fits in unsigned long. Add an xassert to check
7906 XGetWindowProperty overflow. Be more careful about overflow
7907 calculations, and distinguish size from memory overflow better.

7913 in the range -65535 through -1 fit in an X unsigned short.
7914 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7915 result parameters unless successful. Rely on cons_to_unsigned
7916 to report problems with elements; the old code wasn't right anyway.
7917 (x_check_property_data): Check for int overflow; we cannot use
7918 a wider type due to X limits.
7919 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7951 * lisp.h (hash_lookup, hash_put):
7952 * minibuf.c (Ftest_completion):
7953 Use ptrdiff_t for hash table indexes, not int (which is too
7954 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

7988 (x_send_scroll_bar_event): Likewise. Check that the size does not
7989 exceed limits imposed by XClientMessageEvent, as well as the usual
7990 ptrdiff_t and size_t limits.
7992 * keyboard.c: Overflow, signedness and related fixes.
7993 (make_lispy_movement): Use same integer type in forward decl
7994 that is used in the definition.
7995 (read_key_sequence, keyremap_step):
7996 Change bufsize argument back to int, undoing my 2011-03-30 change.
7997 We prefer signed types, and int is wide enough here.
7998 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7999 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8000 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8001 length, not size_t. Use ptrdiff_t for index, not int.
8002 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8003 possibility of integer overflow.

8031 Prefer int to unsigned where either will do.
8032 (tiff_handler): New function, combining the cores of the
8033 old tiff_error_handler and tiff_warning_handler.
8034 This function is rewritten to use vsnprintf and thereby avoid
8035 stack buffer overflows. It uses only the features of vsnprintf
8036 that are common to both POSIX and native Microsoft.
8037 (tiff_error_handler, tiff_warning_handler): Use it.
8038 (tiff_load, gif_load, imagemagick_load_image):

8042 the integer types that MagickCropImage accepts. Don't assume
8043 Vimagemagick_render_type has a nonnegative value. Don't assume
8044 size_t fits in 'long'.
8045 (gs_load): Use printmax_t to print the widest integers possible.

8064 Don't advance `row' beyond the last row of the window.
8066 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8067 into disp_prop; all users changed.

8085 positioning on the newline at EOL of R2L text within L2R
8086 paragraph, and vice versa.
8087 (try_cursor_movement): Check continued rows, in addition to
8088 continuation rows. Fixes unwarranted scroll when point enters a
8089 continued line of R2L text within an L2R paragraph, or vice versa.
8090 (cursor_row_p): Consider the case of point being equal to
8091 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8092 from the end of a short line to the beginning of a continued line
8093 of R2L text within L2R paragraph.

8120 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8121 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8122 candidate is selected by the mouse, and that candidate has a
8123 composed character under the mouse.
8125 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8126 coordinates reported by pos-visible-in-window-p for a composed

8137 composed buffer positions.
8139 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8141 * image.c (gif_load): Don't assume that each subimage has the same
8142 dimensions as the base image. Handle disposal method that is
8143 "undefined" by the gif spec (Bug#9335).
8145 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8147 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8152 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8153 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8154 from an Org mode buffer to a Speedbar frame.
8156 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8157 a composition, take its buffer position from IT->cmp_it.charpos.
8158 Fixes cursor positioning at the beginning of a line that begins
8159 with a composed character.
8161 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8163 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8164 character bidirectional type, use STRONG_L instead. Fixes crashes
8165 in a buffer produced by `describe-categories'.
8167 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8168 members before the level stack, so they would be saved and
8169 restored when copying iterator state. Fixes incorrect reordering
8170 around TABs covered by display properties.
8172 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8205 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8207 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8209 [CYGWIN] (special_realloc): New function.
8210 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8211 requests to realloc storage in the static heap.
8213 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8215 * bidi.c (bidi_initialize): Remove unused local.
8217 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8220 * biditype.h: Remove file.
8221 * makefile.w32-in ($(BLD)/bidi.$(O)):
8222 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8224 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8226 * chartab.c: Improve commentary for the uniprop_table API.
8228 * bidi.c (bidi_paragraph_init): Support zero value of
8229 bidi_ignore_explicit_marks_for_paragraph_level.
8230 (bidi_initialize): Use uniprop_table instead of including
8231 biditype.h and bidimirror.h.
8233 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8234 coordinates of the iterator when restoring from ppos_it.
8237 2011-08-14 Kenichi Handa <handa@m17n.org>
8239 * process.c (create_process): Call setup_process_coding_systems
8240 after the pid of the process is set to -1 (Bug#8162).
8242 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8244 * xdisp.c (move_it_in_display_line_to): Don't invoke
8245 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8246 ppos_it. Fixes vertical cursor motion when line beginning is
8247 covered by an image. (Bug#9296)
8249 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8251 * nsterm.h (ns_run_ascript): Declare.
8252 (NSAPP_DATA2_RUNASSCRIPT): Define.
8254 * nsfns.m (as_script, as_result, as_status): New static variables.
8255 (ns_run_ascript): New function.
8256 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8257 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8258 the event loop. Get status from as_status (Bug#7276).
8260 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8261 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8262 the event loop (Bug#7276).
8264 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8266 * gnutls.c (QCgnutls_bootprop_priority)
8267 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8268 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8269 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8270 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8271 (QCgnutls_bootprop_verify_hostname_error)
8272 (QCgnutls_bootprop_callbacks_verify): Rename from
8273 Qgnutls_bootprop_..., all uses changed.
8275 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8278 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8280 * xfaces.c (Qframe_set_background_mode): Now static.
8281 * dispextern.h (Qframe_set_background_mode): Remove decl.
8283 * process.c (Fnetwork_interface_info): Declare local only if needed.
8285 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8287 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8288 (Fnetwork_interface_list): Allocate in increments of bytes instead
8289 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8290 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8292 (struct ifflag_def): notrailers is smart on OSX.
8293 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8294 Get hardware address with getifaddrs if available.
8296 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8298 * xdisp.c (iterate_out_of_display_property): xassert that
8299 IT->position is set to within IT->object's boundaries. Break from
8300 the loop as soon as EOB is reached; avoids infloops in redisplay
8301 when IT->position is set up wrongly due to some bug.
8302 Set IT->current to match the bidi iterator unconditionally.
8303 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8304 entry. Force push_it to save on the stack the current
8305 buffer/string position, to be restored by pop_it. Fix flags in
8306 the iterator structure wrt the object coming from a display
8307 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8308 properties. (Bug#9284)
8310 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8312 * fontset.c (fontset_get_font_group): Add proper type checks.
8315 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

8318 and LC_VERSION_MIN_MACOSX.
8319 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
8320 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8322 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8324 * xdisp.c (forward_to_next_line_start): Allow to use the
8325 no-display-properties-and-no-overlays under bidi display.
8326 Set disp_pos in the bidi iterator to avoid searches for display
8327 properties and overlays.
8329 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8331 * editfns.c (Fset_time_zone_rule): Document relationship with the
8334 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
8335 the font entity extracted from the cache (Bug#8109).
8337 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8339 * composite.c (autocmp_chars): Don't reset point. That is done by
8340 restore_point_unwind (Bug#5984).
8342 2011-08-07 Juri Linkov <juri@jurta.org>
8344 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8345 to show the arg `TIME' instead of `TIMEVAL'.
8347 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8349 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8350 display property strides EOL and includes a newline, as in
8351 longlines-mode. (Bug#9254)
8352 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8353 word-wrap under bidirectional display. (Bug#9224)
8355 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8356 is non-zero, even if the data buffer is NULL. Fixes a crash in
8357 vertical-motion with longlines-mode. (Bug#9254)
8359 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8361 * bidi.c <bidi_cache_total_alloc>: Now static.
8362 (bidi_initialize): Initialize bidi_cache_total_alloc.
8364 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8367 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8368 amount allocated this far in `bidi_cache_total_alloc'.
8369 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8370 non-zero, only free the data buffer without restoring the cache
8371 contents. All callers changed.
8373 * dispextern.h (bidi_unshelve_cache): Update prototype.
8375 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8376 (move_it_in_display_line, move_it_to)
8377 (move_it_vertically_backward, move_it_by_lines): Replace the call
8378 to xfree to an equivalent call to bidi_unshelve_cache.
8379 (move_it_in_display_line_to): Fix logic of returning
8380 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8382 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8384 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8385 came from a string character with a `cursor' property. (Bug#9229)
8387 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8389 * Makefile.in (LIB_PTHREAD): New variable.
8390 (LIBES): Add LIB_PTHREAD (Bug#9216).
8392 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8393 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8395 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8397 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8399 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8401 * xterm.c (x_find_topmost_parent): New function.
8402 (x_set_frame_alpha): Find topmost parent window with
8403 x_find_topmost_parent and set the property there also (bug#9181).
8404 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8406 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8408 * callproc.c (Fcall_process): Avoid vfork clobbering
8409 the local vars buffer, coding_systems, current_dir.
8411 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8413 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8415 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8417 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8418 so that it is not optimized away.
8420 * xdisp.c (compute_display_string_pos): Remove unused local.
8422 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8424 Fix slow cursor motion and scrolling in large buffers with
8425 selective display, like Org Mode buffers. (Bug#9218)
8427 * dispextern.h (struct bidi_it): New member disp_prop_p.
8429 * xdisp.c: Remove one-slot cache of display string positions.
8430 (compute_display_string_pos): Accept an additional argument
8431 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8432 for a display string or property. If found, set DISP_PROP_P
8435 * bidi.c (bidi_fetch_char): Accept an additional argument
8436 DISP_PROP_P, and pass it to compute_display_string_pos.
8437 Only handle text covered by a display string if DISP_PROP_P is returned
8438 non-zero. All callers of bidi_fetch_char changed.
8440 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8442 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8444 2010-12-03 Don March <don@ohspite.net>
8446 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8447 last character M-[char] is translated to ESC [char] (bug#7541).
8449 2011-08-02 Kenichi Handa <handa@m17n.org>
8451 * lisp.h (uniprop_table): Extern it.
8453 * chartab.c (uniprop_table): Make it non-static.
8455 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8457 * xdisp.c (forward_to_next_line_start): Accept additional argument
8458 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8460 (reseat_at_next_visible_line_start): Use the bidi iterator state
8461 returned by forward_to_next_line_start to restore the state of
8462 it->bidi_it after backing up to previous newline. (Bug#9212)
8464 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8466 * regex.c (re_comp): Protoize.
8467 (re_exec): Fix return type.
8468 (regexec): Fix type of `ret'. (Bug#9203)
8470 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8472 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8473 This is needed if max-image-size is a floating-point number.
8475 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8477 * print.c (print_object): Print empty symbol as ##.
8479 * lread.c (read1): Read ## as empty symbol.
8481 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8483 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8484 setting frame foreground color (Bug#9175).
8485 (x_set_background_color): Likewise.
8487 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8488 contents (Bug#9176).
8489 (EmacsTooltip -init): Remove bezels and add shadows to
8492 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8493 or scroll bar (Bug#8470).
8495 * nsfont.m (nsfont_open): Remove assignment to voffset and
8496 unnecessary vars hshink, expand, hd, full_height, min_height.
8497 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8499 * nsterm.h (nsfont_info): Remove voffset field.
8501 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8503 Implement strike-through and overline on NextStep (Bug#8863).
8505 * nsfont.m (nsfont_open): Use underline position provided by font,
8506 instead of hard-coded value of 2.
8507 (nsfont_draw): Call ns_draw_text_decoration instead.
8509 * nsterm.h: Add declaration for ns_draw_text_decoration.
8511 * nsterm.m (ns_draw_text_decoration): New function for drawing
8512 underline, overline, and strike-through.
8513 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8514 ns_draw_text_decoration. Change treatment of cursor drawing to
8515 accommodate underlining, etc.
8517 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8519 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8522 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8524 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8525 Without this fix, if a signal arrives just after memory fills up,
8526 'malloc' might be invoked reentrantly.
8528 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8529 In other words, assume that every image size is allowed, on non-X
8530 hosts. This assumption is probably wrong, but it lets Emacs compile.
8532 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8534 * regex.c (re_iswctype): Convert return values to boolean.
8536 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8538 * xdisp.c (compute_display_string_pos): Don't use cached display
8539 string position if the buffer had its restriction changed.
8542 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8544 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8546 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8548 Integer signedness and overflow and related fixes. (Bug#9079)
8550 * bidi.c: Integer size and overflow fixes.
8551 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8552 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8553 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8554 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8555 (bidi_find_other_level_edge):
8556 Use ptrdiff_t instead of EMACS_INT where either will do.
8557 This works better on 32-bit hosts configured --with-wide-int.
8558 (bidi_cache_ensure_space): Check for size-calculation overflow.
8559 Use % rather than repeated addition, for better worst-case speed.
8560 Don't set bidi_cache_size until after xrealloc returns, because it
8562 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8563 (bidi_cache_ensure_space): Also check that the bidi cache size
8564 does not exceed that of the largest Lisp string or buffer. See Eli
8565 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8567 * alloc.c (__malloc_size_t): Remove.
8568 All uses replaced by size_t. See Andreas Schwab's note
8569 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8571 * image.c: Improve checking for integer overflow.
8572 (check_image_size): Assume that f is nonnull, since
8573 it is always nonnull in practice. This is one less thing to
8574 worry about when checking for integer overflow later.
8575 (x_check_image_size): New function, which checks for integer
8576 overflow issues inside X.
8577 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8578 This removes the need for a memory_full check.
8579 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8580 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8581 (xbm_read_bitmap_data): Change locals back to 'int', since
8582 their values must fit in 'int'.
8583 (xpm_load_image, png_load, tiff_load):
8584 Invoke x_create_x_image_and_pixmap earlier,
8585 to avoid much needless work if the image is too large.
8586 (tiff_load): Treat overly large images as if
8587 x_create_x_image_and_pixmap failed, not as malloc failures.
8588 (gs_load): Use x_check_image_size.
8590 * gtkutil.c: Omit integer casts.
8591 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8592 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8594 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8596 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8597 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8598 would wrongly return t on a 64-bit host.
8600 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8601 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8602 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8603 and therefore cause GCC to emit a bogus diagnostic in some cases.
8605 * image.c: Integer signedness and overflow and related fixes.
8606 This is not an exhaustive set of fixes, but it's time to
8607 record what I've got.
8608 (lookup_pixel_color, check_image_size): Remove redundant decls.
8609 (check_image_size): Don't assume that arbitrary EMACS_INT values
8610 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8611 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8612 (tiff_load, imagemagick_load_image):
8613 Check for overflow in size calculations.
8614 (x_create_x_image_and_pixmap): Remove unnecessary test for
8615 xmalloc returning NULL; that can't happen.
8616 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8617 (xpm_color_bucket): Use better integer hashing function.
8618 (xpm_cache_color): Don't possibly over-allocate memory.
8619 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8620 (gif_memory_source):
8621 Use ptrdiff_t, not int or size_t, to record sizes.
8622 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8623 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8624 either works, as we prefer signed integers.
8625 (tiff_read_from_memory, tiff_write_from_memory):
8626 Return tsize_t, not size_t, since that's what the TIFF API wants.
8627 (tiff_read_from_memory): Don't fail simply because the read would
8628 go past EOF; instead, return a short read.
8629 (tiff_load): Omit no-longer-needed casts.
8630 (Fimagemagick_types): Don't assume size fits into 'int'.
8632 Improve hashing quality when configured --with-wide-int.
8633 * fns.c (hash_string): New function, taken from sxhash_string.
8634 Do not discard information about ASCII character case; this
8635 discarding is no longer needed.
8636 (sxhash-string): Use it. Change sig to match it. Caller changed.
8637 * lisp.h: Declare it.
8638 * lread.c (hash_string): Remove, since we now use fns.c's version.
8639 The fns.c version returns a wider integer if --with-wide-int is
8640 specified, so this should help the quality of the hashing a bit.
8642 * emacs.c: Integer overflow minor fix.
8643 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8644 Define only if GNU_LINUX.
8645 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8647 * dispnew.c: Integer signedness and overflow fixes.
8648 Remove unnecessary forward decls, that were a maintenance hassle.
8649 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8651 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8652 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8653 (prepare_desired_row, line_draw_cost):
8654 Use int, not unsigned, where either works.
8655 (save_current_matrix, restore_current_matrix):
8656 Use ptrdiff_t, not size_t, where either works.
8657 (init_display): Check for overflow more accurately, and without
8658 relying on undefined behavior.
8660 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8661 Remove, replacing with the new symbols in lisp.h. All uses changed.
8662 * fileio.c (make_temp_name):
8663 * filelock.c (lock_file_1, lock_file):
8664 * xdisp.c (message_dolog):
8665 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8666 Use pMd etc. instead.
8667 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8668 replacing the pWIDE etc. symbols removed from editfns.c.
8670 * keyboard.h (num_input_events): Now uintmax_t.
8671 This is (very slightly) less likely to mess up due to wraparound.
8674 * buffer.c: Integer signedness fixes.
8675 (alloc_buffer_text, enlarge_buffer_text):
8676 Use ptrdiff_t rather than size_t when either will do, as we prefer
8679 * alloc.c: Integer signedness and overflow fixes.
8680 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8681 (__malloc_size_t): Default to size_t, not to int.
8682 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8683 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8684 Prefer ptrdiff_t to size_t when either would do, as we prefer
8686 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8687 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8688 Now const. Initialize with values that are in range even if char
8690 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8691 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8692 These functions do the right thing with sizes > 2**32.
8693 (check_depth): Now ptrdiff_t, not int.
8694 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8695 Adjust to new way of storing sizes. Check for size overflow bugs
8697 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8698 slightly wrong anyway, as it missed one instance of
8699 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8700 (refill_memory_reserve): Omit needless cast to size_t.
8701 (mark_object_loop_halt): Mark as externally visible.
8703 * xselect.c: Integer signedness and overflow fixes.
8704 (Fx_register_dnd_atom, x_handle_dnd_message):
8705 Use ptrdiff_t, not size_t, since we prefer signed.
8706 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8707 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8708 x_dnd_atoms_size and x_dnd_atoms_length.
8710 * doprnt.c: Prefer signed to unsigned when either works.
8712 * doprnt.c (doprnt):
8714 * xdisp.c (vmessage):
8715 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8716 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8717 prefer signed arithmetic to avoid comparison confusion.
8718 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8719 but is a bit tricky.
8721 Assume freestanding C89 headers, string.h, stdlib.h.
8722 * data.c, doprnt.c, floatfns.c, print.c:
8723 Include float.h unconditionally.
8724 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8725 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8726 * regex.c: Likewise for stddef.h, string.h.
8727 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8728 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8729 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8730 (STDC_HEADERS): Remove obsolete defines.
8731 * sysdep.c: Include limits.h unconditionally.
8733 Assume support for memcmp, memcpy, memmove, memset.
8734 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8735 * regex.c (memcmp, memcpy):
8736 Remove; we assume C89 now.
8738 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8739 (__malloc_safe_bcopy): Remove; no longer needed.
8741 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8742 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8743 well either way, and we prefer signed to unsigned.
8745 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8747 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8748 closes the connection while we're reading (bug#9182).
8750 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8752 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8753 are specified (Bug#9168).
8755 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8757 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8758 Found by GCC static checking and --with-wide-int on a 32-bit host.
8760 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8762 * xdisp.c (compute_display_string_pos): Fix logic of caching
8763 previous display string position. Initialize cached_prev_pos to
8764 -1. Fixes slow-down at the beginning of a buffer.
8766 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8768 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8769 for attrs[LFACE_FONTSET_INDEX].
8771 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8773 * xml.c (parse_region): Remove unused local
8774 that was recently introduced.
8776 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8778 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8779 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8781 * xdisp.c (move_it_in_display_line_to): Record the best matching
8782 position for TO_CHARPOS while scanning the line, and restore it on
8783 exit if none of the characters scanned was an exact match.
8784 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8785 when exact match is impossible due to invisible text, and the
8786 lines are truncated.
8788 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8790 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8793 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8795 Fix a significant slow-down of cursor motion with C-n, C-p,
8796 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8797 auto-repeat under bidi redisplay in fontified buffers.
8798 * xdisp.c (compute_stop_pos_backwards): New function.
8799 (next_element_from_buffer): Call compute_stop_pos_backwards to
8800 find a suitable prev_stop when we find ourselves before
8802 (reseat): Don't look for prev_stop, as that could mean a very long
8804 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8805 <cached_disp_overlay_modiff>: Cache for last found display string
8807 (compute_display_string_pos): Return the cached position if asked
8808 about the same buffer in the same area of character positions, and
8809 the buffer wasn't changed since the time the display string
8810 position was cached.
8812 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8814 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8815 is an integer, which is important for empty lines. (Bug#9149)
8817 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8819 * frame.c (Fmodify_frame_parameters): In tty case, update the
8820 default face if necessary (Bug#4238).
8822 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8824 * editfns.c (Fstring_to_char): No need to explain what a character
8825 is in the docstring (Bug#6576).
8827 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8829 * xml.c (parse_region): Make sure we always return a tree.
8831 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8833 * xml.c (parse_region): If a document contains only comments,
8836 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8838 * xml.c (make_dom): Return comments, too.
8840 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8843 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8844 and the surrounding thread.
8845 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8846 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8847 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8849 * s/openbsd.h (BROKEN_SIGIO): Define.
8850 * unexelf.c (unexec) [__OpenBSD__]:
8851 Don't update the .mdebug section of the Alpha COFF symbol table.
8853 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8855 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8858 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8860 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8861 This fixes some race conditions on the permissions of any newly
8864 * alloc.c (valid_pointer_p): Use pipe, not open.
8865 This fixes some permissions issues when debugging.
8867 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8868 If fchown fails to set both uid and gid, try to set just gid,
8869 as that is sometimes allowed. Adjust the file's mode to eliminate
8870 setuid or setgid bits that are inappropriate if fchown fails.
8872 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8874 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8875 to compare Lisp_Objects.
8876 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8877 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8878 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8880 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8882 * lread.c (read_integer): Unread even EOF character.
8883 (read1): Likewise. Properly record start position of symbol.
8885 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8886 symbol character follows.
8888 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8890 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8891 This works around a problem with the previous change to Fcopy_file.
8892 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8893 and without this change, GCC might complain about discarding
8894 fchown's return value.
8896 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8898 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8900 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8902 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8904 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8906 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8907 it's used from the C level.
8909 * process.c: Use the same condition for POLL_FOR_INPUT in both
8910 keyboard.c and process.c (bug#1858).
8912 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8914 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8915 (Fgnutls_boot): Use it.
8917 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8919 * doc.c (Fsubstitute_command_keys): Revert last change.
8921 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8923 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8924 quotes the next character, and doesn't affect other longer
8925 sequences (bug#8935).
8927 * lread.c (syms_of_lread): Clarify that is isn't only
8928 `eval-buffer' and `eval-defun' that's affected by
8929 `lexical-binding' (bug#8460).
8931 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8933 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8934 bidi redisplay when a line includes both an image and is truncated.
8936 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8938 Fix minor problems found by static checking.
8939 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8940 (elsz): Now a signed constant, not a size_t var. We prefer signed
8941 types to unsigned, to avoid integer comparison confusion. Without
8942 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8943 "cannot optimize loop, the loop counter may overflow", a symptom
8945 * indent.c (Fvertical_motion): Mark locals as initialized.
8946 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8948 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8950 * search.c (Fre_search_backward): Mention `case-fold-search' in
8951 all the re_search_* functions (bug#8138).
8953 * keyboard.c (Fopen_dribble_file): Document when the file is
8956 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8958 * bidi.c (bidi_dump_cached_states): Fix format of displaying

8963 (compute_display_string_end): Accept additional argument STRING.
8964 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8965 (reseat_to_string): Initialize bidi_it->string.s and
8966 bidi_it->string.schars.
8967 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8968 NULL (avoids a crash in bidi_paragraph_init).
8969 Initialize itb.string.lstring.
8970 (init_iterator): Call bidi_init_it only of a valid
8971 buffer position was specified. Initialize paragraph_embedding to
8973 (reseat_to_string): Initialize the bidi iterator.
8974 (display_string): If we need to ignore text properties of
8975 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8976 original value of -1 will not work with bidi.)
8977 (compute_display_string_pos): First arg is now struct
8978 `text_pos *'; all callers changed. Support display properties on
8980 (compute_display_string_end): Support display properties on Lisp
8982 (init_iterator, reseat_1, reseat_to_string): Initialize the
8983 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8984 when iterating on a string not from display properties).
8985 (compute_display_string_pos, compute_display_string_end):
8986 Fix calculation of the object to scan. Fixes an error when using
8988 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8989 base_level_stop; instead, set base_level_stop to BEGV.
8990 Fixes crashes in vertical-motion.
8991 (next_element_from_buffer): Improve commentary for when
8992 the iterator is before prev_stop.
8993 (init_iterator): Initialize bidi_p from the default value of
8994 bidi-display-reordering, not from buffer-local value. Use the
8995 buffer-local value only if initializing for buffer iteration.
8996 (handle_invisible_prop): Support invisible properties on strings
8997 that are being bidi-reordered.
8998 (set_iterator_to_next): Support bidi reordering of C strings and
9000 (next_element_from_string): Support bidi reordering of Lisp
9002 (handle_stop_backwards): Support Lisp strings as well.
9003 (display_string): Support display of R2L glyph rows.
9004 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9005 (init_iterator): Don't initialize it->bidi_p for strings
9007 (reseat_to_string): Initialize it->bidi_p for strings here.
9008 (next_element_from_string, next_element_from_c_string)
9009 (next_element_from_buffer): Add xassert's for correspondence
9010 between IT's object being iterated and it->bidi_it.string
9012 (face_before_or_after_it_pos): Support bidi iteration.
9013 (next_element_from_c_string): Handle the case of the first string
9014 character that is not the first one in the visual order.
9015 (get_visually_first_element): New function, refactored from common
9016 parts of next_element_from_buffer, next_element_from_string, and
9017 next_element_from_c_string.
9018 (tool_bar_lines_needed, redisplay_tool_bar)
9019 (display_menu_bar): Force left-to-right direction. Add a FIXME
9020 comment for making that be controlled by a user option.
9021 (push_it, pop_it): Save and restore the state of the
9022 bidi iterator. Save and restore the bidi_p flag.
9023 (pop_it): Iterate out of display property for string iteration as
9025 (iterate_out_of_display_property): Support iteration over strings.
9026 (handle_single_display_spec): Set up it->bidi_it for iteration
9027 over a display string, and call bidi_init_it.
9028 (handle_single_display_spec, next_overlay_string)

9030 iterator for displaying display or overlay strings.
9031 (forward_to_next_line_start): Don't use the shortcut if
9033 (back_to_previous_visible_line_start): If handle_display_prop
9034 pushed the iterator stack, restore the internal state of the bidi
9035 iterator by calling bidi_pop_it same number of times.
9036 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9037 and we are bidi-iterating, don't decrement the iterator position;
9038 instead, set the first_elt flag in the bidi iterator, to produce
9040 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9041 (push_display_prop): xassert that we are iterating a buffer.
9042 (push_it, pop_it): Save and restore paragraph_embedding member.
9043 (handle_single_display_spec, next_overlay_string)
9044 (get_overlay_strings_1, reseat_1, reseat_to_string)
9045 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9046 correctly. Don't assume unibyte strings are not bidi-reordered.
9047 (compute_display_string_pos)
9048 (compute_display_string_end): Fix handling the case of C string.
9049 (push_it, pop_it): Save and restore from_disp_prop_p.
9050 (handle_single_display_spec, push_display_prop): Set the
9051 from_disp_prop_p flag.
9052 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9053 (pop_it): Call iterate_out_of_display_property only if we are
9054 popping after iteration over a string that came from a display
9055 property. Fix a typo in popping stretch info. Add an assertion
9056 for verifying that the iterator position is in sync with the bidi
9058 (handle_single_display_spec, get_overlay_strings_1)
9059 (push_display_prop): Fix initialization of paragraph direction for
9060 string when that of the parent object is not yet determined.
9061 (reseat_1): Call bidi_init_it to resync the bidi
9062 iterator with IT's position. (Bug#7616)
9063 (find_row_edges): If ROW->start.pos gives position
9064 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

9072 (try_scrolling, redisplay_window, display_line): Use them when
9073 saving a temporary copy of the iterator and restoring it back.
9074 (back_to_previous_visible_line_start, reseat_1)
9075 (init_iterator): Empty the bidi cache "stack".
9076 (move_it_in_display_line_to): If iterator ended up at
9077 EOL, but we never saw any buffer positions smaller than
9078 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9079 motion in bidi-reordered lines.
9080 (move_it_in_display_line_to): Record prev_method and prev_pos
9081 immediately before the call to set_iterator_to_next. Fixes cursor
9082 motion in bidi-reordered lines with stretch glyphs and strings
9083 displayed in margins. (Bug#8133) (Bug#8867)
9084 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9086 (pos_visible_p): Support positions in bidi-reordered lines.
9087 Save and restore bidi cache.
9089 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9090 (bidi_paragraph_info): Delete unused struct.
9091 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9092 (bidi_cache_start): New variable.
9093 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

9098 (bidi_level_of_next_char, bidi_find_other_level_edge)
9099 (bidi_move_to_visually_next): Compare cache index with
9100 bidi_cache_start rather than with zero.
9101 (bidi_fetch_char): Accept new argument STRING; all callers
9102 changed. Support iteration over a string. Support strings with
9103 display properties. Support unibyte strings. Fix the type of
9104 `len' according to what STRING_CHAR_AND_LENGTH expects.
9105 (bidi_paragraph_init, bidi_resolve_explicit_1)
9106 (bidi_resolve_explicit, bidi_resolve_weak)

9112 changed to -1 and -2, respectively.
9113 (bidi_char_at_pos): New function.
9114 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
9115 Call it instead of FETCH_MULTIBYTE_CHAR.
9116 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
9117 initialized to valid values.
9118 (bidi_init_it): Don't initialize charpos and bytepos with invalid
9120 (bidi_level_of_next_char): Allow the sentinel "position" to pass
9121 the test for valid cached positions. Fix the logic for looking up

9470 (clone_per_buffer_values): Don't assume that

9511 Random fixes. E.g., (random) never returned negative values.
9512 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9513 subseconds part to the entropy, as that's a bit more random.
9514 Prefer signed to unsigned, since the signedness doesn't matter and
9515 in general we prefer signed. When given a limit, use a
9516 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9517 latter isn't right if USE_2_TAGS_FOR_INTS.
9518 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9519 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9532 This is more efficient than Ffile_directory_p and avoids a minor race.
9534 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9536 * buffer.c (Foverlay_put): Say what the return value is
9539 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9543 error be more correct.
9545 * fns.c (Frequire): Remove the mention of the .gz files, since
9546 that's installation-specific, but keep the mention of

9562 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9664 * eval.c (struct backtrace): Simplify and port the data structure.
9665 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9666 signed bit field, as this assumption is not portable and it makes
9667 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9668 "char debug_on_exit : 1" as this is not portable either; instead,
9669 use the portable "unsigned int debug_on_exit : 1". Remove unused
9670 member evalargs. Remove obsolete comments about cc bombing out.

9840 Don't set size unless allocation succeeds.
9842 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9843 for sizes. Check for string overflow more accurately.

9883 Move to minibuffer.el.
9885 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9887 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9888 The following patches are for when GLYPH_DEBUG && !XASSERT.

9902 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9904 (debug_method_add): Use va_list and vsprintf rather than relying
9905 on undefined behavior with wrong number of arguments.
9906 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9907 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9908 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9909 since we're not interested in debugging glyphs with old libraries.
9910 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9911 GCC 4.6.0's static checking.
9913 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

9952 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9953 (x_session_initialize): Do not assume string length fits in int.
9955 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9956 This is unlikely, but can occur if DPI is outlandish.
9958 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9959 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

9997 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9998 Reformulate so as not to need the command string.
9999 Invoke gzip -cd rather than gunzip, as it's more portable.
10000 (lock_info_type, lock_file_1, lock_file):
10001 Don't assume pid_t and time_t fit in unsigned long.
10002 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10003 (current_lock_owner): Prefer signed type for sizes.
10004 Use memcpy, not strncpy, where memcpy is what is really wanted.
10005 Don't assume (via atoi) that time_t and pid_t fit in int.
10006 Check for time_t and/or pid_t out of range, e.g., via a network share.
10007 Don't alloca where an auto var works fine.
10009 * fileio.c: Fix some integer overflow issues.
10010 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10011 Don't assume string length fits in int.
10012 (directory_file_name): Don't assume string length fits in long.

10037 All uses changed. This doesn't fix a bug, but it simplifies the
10038 code away from its former Hollerith-constant appearance, and it's
10039 one less 'int' to worry about when looking at integer-overflow issues.
10040 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10042 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10043 This didn't break anything, but it didn't help either.
10044 It's confusing to put a bogus integer in a place where the actual
10045 value does not matter.
10046 (LIST_END_P): Remove unused macro and its bogus comment.
10047 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10049 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10050 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10052 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10053 We prefer signed types, and the value cannot exceed the EMACS_INT
10054 range anyway (because otherwise the length would not be representable).
10055 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10056 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10057 This avoids a GCC warning when WIDE_EMACS_INT.
10059 * indent.c (sane_tab_width): New function.
10060 (current_column, scan_for_column, Findent_to, position_indentation)
10061 (compute_motion): Use it. This is just for clarity.
10062 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10064 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10066 * lisp.h (lint_assume): New macro.
10067 * composite.c (composition_gstring_put_cache):
10068 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10070 * editfns.c, insdel.c:
10071 Omit unnecessary forward decls, to simplify future changes.
10073 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10075 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10077 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10078 Use much-faster test for byte-length change.
10079 Don't assume string byte-length fits in 'int'.
10080 Check that character arg fits in 'int'.
10081 (mapcar1): Declare byte as byte, for clarity.
10083 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10085 * fns.c (concat): Catch string overflow earlier.
10086 Do not rely on integer wraparound.
10088 * dispextern.h (struct it.overlay_strings_charpos)
10089 (struct it.selective): Now EMACS_INT, not int.
10090 * xdisp.c (forward_to_next_line_start)
10091 (back_to_previous_visible_line_start)
10092 (reseat_at_next_visible_line_start, next_element_from_buffer):
10093 Don't arbitrarily truncate the value of 'selective' to int.
10095 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10097 * composite.c: Don't truncate sizes to 'int'.
10098 (composition_gstring_p, composition_reseat_it)
10099 (composition_adjust_point): Use EMACS_INT, not int.
10100 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10101 not EMACS_UINT, for indexes.
10103 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10105 * buffer.c: Include <verify.h>.
10106 (struct sortvec.priority, struct sortstr.priority):
10107 Now EMACS_INT, not int.
10108 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10109 (struct sortstr.size, record_overlay_string)
10110 (struct sortstrlist.size, struct sortlist.used):
10111 Don't truncate size to int.
10112 (record_overlay_string): Check for size-calculation overflow.
10113 (init_buffer_once): Check at compile-time, not run-time.
10115 2011-06-22 Jim Meyering <meyering@redhat.com>
10117 Don't leak an XBM-image-sized buffer
10118 * image.c (xbm_load): Free the image buffer after using it.
10120 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10123 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10124 that Sun C diagnosed.
10125 * fns.c (secure_hash): Fix pointer signedness issue.
10126 * intervals.c (static_offset_intervals): New function.
10127 (offset_intervals): Use it.
10129 2011-06-21 Leo Liu <sdl.web@gmail.com>
10132 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10135 * fns.c (secure_hash): Rename from crypto_hash_function and change
10136 the first arg to accept symbols.
10137 (Fsecure_hash): New primitive.
10138 (syms_of_fns): New symbols.
10140 2011-06-20 Deniz Dogan <deniz@dogan.se>
10142 * process.c (Fset_process_buffer): Clarify return value in
10145 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10147 * dispnew.c (add_window_display_history): Use BVAR.
10149 * xdisp.c (debug_method_add): Use BVAR.
10150 (check_window_end, dump_glyph_matrix, dump_glyph)
10151 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10153 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10156 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10157 check till after the cache is created in init_frame_faces.
10159 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10161 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10163 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10165 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10166 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10167 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10169 Improve buffer-overflow checking (Bug#8873).
10170 * fileio.c (Finsert_file_contents):
10171 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10172 Remove the old (too-loose) buffer overflow checks.
10173 They weren't needed, since make_gap checks for buffer overflow.
10174 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10175 The old code merely checked for Emacs fixnum overflow, and relied
10176 on undefined (wraparound) behavior. The new code avoids undefined
10177 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10179 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10180 Tune. Don't use wider integers than needed. Don't use alloca.
10181 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10183 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10185 * insdel.c, lisp.h (buffer_overflow): New function.
10186 (insert_from_buffer_1, replace_range, replace_range_2):
10187 * insdel.c (make_gap_larger):
10188 * editfns.c (Finsert_char):
10189 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10191 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10193 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10195 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10197 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10198 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10200 * fileio.c: Don't assume EMACS_INT fits in off_t.
10201 (emacs_lseek): New static function.
10202 (Finsert_file_contents, Fwrite_region): Use it.
10203 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10205 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10207 * fns.c: Don't overflow int when computing a list length.
10208 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10209 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10210 truncation on 64-bit hosts. Check for QUIT every
10211 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10212 faster and is responsive enough.
10213 (Flength): Report an error instead of overflowing an integer.
10214 (Fsafe_length): Return a float if the value is not representable
10215 as a fixnum. This shouldn't happen except in contrived situations.
10216 (Fnthcdr, Fsort): Don't assume list length fits in int.
10217 (Fcopy_sequence): Don't assume vector length fits in int.
10219 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10220 (header_size, word_size): New constants.
10221 (allocate_vectorlike): Don't check size overflow here.
10222 (allocate_vector): Check it here instead, since this is the only
10223 caller of allocate_vectorlike that could cause overflow.
10224 Check that the new vector's length is representable as a fixnum.
10226 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10227 The previous code was bogus. For example, next_almost_prime (32)
10228 returned 39, which is undesirable as it is a multiple of 3; and
10229 next_almost_prime (24) returned 25, which is a multiple of 5 so
10230 why was the code bothering to check for multiples of 7?
10232 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10234 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10236 Variadic C functions now count arguments with ptrdiff_t.
10237 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10238 Back then I didn't know that the Emacs coding style prefers signed int.
10239 Also, in the meantime I found a few more instances where arguments
10240 were being counted with int, which may truncate counts on 64-bit
10241 machines, or EMACS_INT, which may be unnecessarily wide.
10242 * lisp.h (struct Lisp_Subr.function.aMANY)
10243 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10244 Arg counts are now ptrdiff_t, not size_t.
10245 All variadic functions and their callers changed accordingly.
10246 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10247 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10248 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10249 * callint.c (Fcall_interactively): Check arg count for overflow,
10250 to avoid potential buffer overrun. Use signed char, not 'int',
10251 for 'varies' array, so that we needn't bother to check its size
10252 calculation for overflow.
10253 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10254 * eval.c (apply_lambda):
10255 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10256 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10257 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10259 * callint.c (Fcall_interactively): Don't use index var as event count.
10261 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10262 * mem-limits.h (SIZE): Remove; no longer used.
10264 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10266 Remove unnecessary casts.
10267 * xterm.c (x_term_init):
10268 * xfns.c (x_set_border_pixel):
10269 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10270 These aren't needed now that we assume ANSI C.
10272 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10273 It's more likely to cause problems (due to unsigned overflow)
10276 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10278 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10280 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10282 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10284 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10286 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10288 GLYPH_CODE_FACE returns EMACS_INT, not int.
10289 * dispextern.h (merge_faces):
10290 * xfaces.c (merge_faces):
10291 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10292 Don't assume EMACS_INT fits in int.
10294 * character.h (CHAR_VALID_P): Remove unused parameter.
10295 * fontset.c, lisp.h, xdisp.c: All uses changed.
10297 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10299 * fns.c (concat): Minor tuning based on overflow analysis.
10300 This doesn't fix any bugs. Use int to hold character, instead
10301 of constantly refetching from Emacs object. Use XFASTINT, not
10302 XINT, for value known to be a character. Don't bother comparing
10303 a single byte to 0400, as it's always less.
10305 * floatfns.c (Fexpt):
10306 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10308 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10311 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10313 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10314 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10315 incorrectly succeed when S was a string, because 4294967386 was
10316 truncated before it was used.
10318 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10319 Otherwise, an out-of-range integer could cause undefined behavior
10322 * composite.c: Use int, not EMACS_INT, for characters.
10323 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10324 EMACS_INT, for values that are known to be in character range.
10325 This doesn't fix any bugs but is the usual style inside Emacs and
10326 may generate better code on 32-bit machines.
10328 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10329 This is for reasons similar to the recent CHAR_STRING fix.
10330 * charset.c (Fencode_char): Check that character arg is actually
10331 a character. Pass an int to ENCODE_CHAR.
10332 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10333 wider than 'int', as a compile-time check to prevent future regressions
10336 * character.c (char_string): Remove unnecessary casts.
10338 Make sure a 64-bit char is never passed to CHAR_STRING.
10339 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10340 by silently ignoring the top 32 bits, allowing some values
10341 that were far too large to be valid characters.
10342 * character.h: Include <verify.h>.
10343 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10344 arguments are no wider than unsigned, as a compile-time check
10345 to prevent future regressions in this area.
10347 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10348 (Fsubst_char_in_region):
10350 * xdisp.c (decode_mode_spec_coding):
10351 Adjust to CHAR_STRING's new requirement.
10352 * editfns.c (Finsert_char, Fsubst_char_in_region):
10353 * fns.c (concat): Check that character args are actually
10354 characters. Without this test, these functions did the wrong
10355 thing with wildly out-of-range values on 64-bit hosts.
10357 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10358 These casts should not be needed on 32-bit hosts, either.
10359 * keyboard.c (read_char):
10360 * lread.c (Fload): Remove casts to unsigned.
10362 * lisp.h (UNSIGNED_CMP): New macro.
10363 This fixes comparison bugs on 64-bit hosts.
10364 (ASCII_CHAR_P): Use it.
10365 * casefiddle.c (casify_object):
10366 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10367 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10368 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10369 * dispextern.h (FACE_FROM_ID):
10370 * keyboard.c (read_char): Use UNSIGNED_CMP.
10372 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10373 not to EMACS_INT, to avoid GCC warning.
10375 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10377 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10378 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10379 isn't needed on 32-bit machines.
10381 * buffer.c (Fgenerate_new_buffer_name):
10382 Use EMACS_INT for count, not int.
10383 (advance_to_char_boundary): Return EMACS_INT, not int.
10385 * data.c (Qcompiled_function): Now static.
10387 * window.c (window_body_lines): Now static.
10389 * image.c (gif_load): Rename local to avoid shadowing.
10391 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10392 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10393 * alloc.c (make_save_value): Integer argument is now of type
10394 ptrdiff_t, not int.
10395 (mark_object): Use ptrdiff_t, not int.
10396 * lisp.h (pD): New macro.
10397 * print.c (print_object): Use it.
10399 * alloc.c: Use EMACS_INT, not int, to count objects.
10400 (total_conses, total_markers, total_symbols, total_vector_size)
10401 (total_free_conses, total_free_markers, total_free_symbols)
10402 (total_free_floats, total_floats, total_free_intervals)
10403 (total_intervals, total_strings, total_free_strings):
10404 Now EMACS_INT, not int. All uses changed.
10405 (Fgarbage_collect): Compute overall total using a double, so that
10406 integer overflow is less likely to be a problem. Check for overflow
10407 when converting back to an integer.
10408 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10409 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10410 These were 'int' variables that could overflow on 64-bit hosts;
10411 they were never used, so remove them instead of repairing them.
10412 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10413 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10414 Previously, this ceilinged at INT_MAX, but that doesn't work on
10416 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10418 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10419 (allocate_vectorlike): Check for ptrdiff_t overflow.
10420 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10421 when a (possibly-narrower) signed value would do just as well.
10422 We prefer using signed arithmetic, to avoid comparison confusion.
10424 * alloc.c: Catch some string size overflows that we were missing.
10425 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10426 for convenience in STRING_BYTES_MAX.
10427 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10428 The definition here is exact; the one in lisp.h was approximate.
10429 (allocate_string_data): Check for string overflow. This catches
10430 some instances we weren't catching before. Also, it catches
10431 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10432 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10433 and ptrdiff_t and EMACS_INT are both 64 bits.
10435 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10436 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10437 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10439 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10441 * alloc.c (Fmake_string): Check for out-of-range init.
10443 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10445 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10447 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10449 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10450 xg_get_default_scrollbar_width.
10452 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10453 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10454 (style_changed_cb): Call update_theme_scrollbar_width and call
10455 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10456 all frames (Bug#8505).
10457 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10458 Call gtk_window_set_resizable if HAVE_GTK3.
10459 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10460 and height if HAVE_GTK3 (Bug#8505).
10461 (scroll_bar_width_for_theme): New variable.
10462 (update_theme_scrollbar_width): New function.
10463 (xg_get_default_scrollbar_width): Move code to
10464 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10465 (xg_initialize): Call update_theme_scrollbar_width.
10467 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10469 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10471 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10473 * frame.c (make_frame): Call other_buffer_safely instead of
10476 * window.c (temp_output_buffer_show): Call display_buffer with
10477 second argument Vtemp_buffer_show_specifiers and reset latter
10478 immediately after the call.
10479 (Vtemp_buffer_show_specifiers): New variable.
10480 (auto_window_vscroll_p, next_screen_context_lines)

10929 (Fframe_root_window, Fframe_first_window)
10930 (Fframe_selected_window): Move here from frame.c. Accept frame
10931 or arbitrary window as argument. Update doc-strings.
10932 (Fminibuffer_window): Move up in code.
10933 (Fwindow_minibuffer_p): Move up in code and simplify.
10934 (Fset_frame_selected_window): Move here from frame.c.
10936 (Fselected_window, select_window, Fselect_window): Move up in
10937 code. Minor doc-string fixes.
10939 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
10941 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
10942 Do not assume that spare memory exists; that assumption is valid
10943 only if SYSTEM_MALLOC.
10944 (LARGE_REQUEST): New macro, so that the issue of large requests
10945 is separated from the issue of spare memory.
10947 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
10949 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

10973 (x_clipboard_manager_save): Add return value.
10974 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
10975 New error handlers.
10976 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
10977 Obey Vx_select_enable_clipboard_manager. Catch errors in
10978 x_clipboard_manager_save (Bug#8779).
10979 (Vx_select_enable_clipboard_manager): New variable.
10980 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
10982 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
10984 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
10986 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10988 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
10989 in the current matrix if keep_current_p is non-zero.

10993 * bidi.c (bidi_level_of_next_char): Fix last change.
10995 2011-06-03 Eli Zaretskii <eliz@gnu.org>
10997 Support bidi reordering of text covered by display properties.
10999 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11000 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11001 (bidi_cache_search, bidi_cache_iterator_state)
11002 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11003 (bidi_level_of_next_char, bidi_move_to_visually_next):
11004 Support character positions inside a run of characters covered by a
11006 (bidi_paragraph_init, bidi_resolve_explicit_1)
11007 (bidi_level_of_next_char): Call bidi_fetch_char and
11008 bidi_fetch_char_advance instead of FETCH_CHAR and
11009 FETCH_CHAR_ADVANCE.

11011 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11013 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11014 instead of using explicit *_CHAR codes.
11015 (bidi_resolve_explicit, bidi_resolve_weak):
11016 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11017 bidirectional text is supported only in multibyte buffers.
11018 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11019 it to initialize the frame_window_p member of struct bidi_it.
11020 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11021 (bidi_resolve_explicit, bidi_resolve_weak)

11023 bidi_it->nchars is non-positive.
11024 (bidi_level_of_next_char): Don't try to lookup the cache for the
11025 next/previous character if nothing is cached there yet, or if we
11026 were just reseat()'ed to a new position.
11028 * xdisp.c (set_cursor_from_row): Set start and stop points
11029 according to the row's direction when priming the loop that looks
11030 for the glyph on which to display cursor.
11031 (single_display_spec_intangible_p): Function deleted.
11032 (display_prop_intangible_p): Reimplement to call
11033 handle_display_spec instead of single_display_spec_intangible_p.
11034 Accept 3 additional arguments needed by handle_display_spec.
11035 This fixes incorrect cursor motion across display property with complex
11036 values: lists, `(when COND...)' forms, etc.
11037 (single_display_spec_string_p): Support property values that are
11038 lists with the argument STRING its top-level element.
11039 (display_prop_string_p): Fix the condition for processing a
11040 property that is a list to be consistent with handle_display_spec.
11041 (handle_display_spec): New function, refactored from the
11042 last portion of handle_display_prop.
11043 (compute_display_string_pos): Accept additional argument
11044 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11045 value of a `display' property is a "replacing spec".
11046 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11047 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11048 the display property, but just return a value indicating whether
11049 the display property will replace the characters it covers.
11050 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11051 frame_window_p members of struct bidi_it.
11052 (compute_display_string_pos, compute_display_string_end):
11054 (push_it): Accept second argument POSITION, where pop_it should
11055 jump to continue iteration.
11056 (reseat_1): Initialize bidi_it.disp_pos.
11058 * keyboard.c (adjust_point_for_property): Adjust the call to
11059 display_prop_intangible_p to its new signature.
11061 * dispextern.h (struct bidi_it): New member frame_window_p.
11062 (bidi_init_it): Update prototypes.
11063 (display_prop_intangible_p): Update prototype.
11064 (compute_display_string_pos, compute_display_string_end):
11065 Declare prototypes.
11066 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11069 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11071 Malloc failure behavior now depends on size of allocation.
11072 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11073 * lisp.h: Change signatures accordingly.
11074 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11075 All callers changed. (Bug#8762)
11077 * gnutls.c: Use Emacs's memory allocators.
11078 Without this change, the gnutls library would invoke malloc etc.
11079 directly, which causes problems on non-SYNC_INPUT hosts, and which
11080 runs afoul of improving memory_full behavior. (Bug#8761)
11081 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11082 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11083 xfree instead of the default malloc, realloc, free.
11084 (Fgnutls_boot): No need to check for memory allocation failure,
11085 since xmalloc does that for us.
11087 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11088 * category.c (hash_get_category_set):
11089 * ccl.c (ccl_driver):
11090 * charset.c (Fdefine_charset_internal):
11091 * charset.h (struct charset.hash_index):

11093 (composition_gstring_put_cache):
11094 * composite.h (struct composition.hash_index):
11095 * dispextern.h (struct image.hash):
11096 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11097 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11098 (hashfn_equal, hashfn_user_defined, make_hash_table)
11099 (maybe_resize_hash_table, hash_lookup, hash_put)
11100 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11101 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11102 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11103 * image.c (make_image, search_image_cache, lookup_image)
11104 (xpm_put_color_table_h):
11105 * lisp.h (struct Lisp_Hash_Table):
11106 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11107 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11108 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11109 * alloc.c (allocate_vectorlike):
11110 Check for overflow in vector size calculations.
11111 * ccl.c (ccl_driver):
11112 Check for overflow when converting EMACS_INT to int.
11113 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11114 need to be updated by these changes.
11115 * fns.c (make_hash_table, maybe_resize_hash_table):
11116 Check for integer overflow with large hash tables.
11117 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11118 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11119 (SXHASH_REDUCE): New macro.
11120 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11121 Use it instead of discarding useful hash info with large hash values.
11122 (sxhash_float): New function.
11123 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11124 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11125 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11126 Rewrite to use FIXNUM_BITS, as this simplifies things.
11127 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11128 Adjust signatures to match updated version of code.
11129 (consing_since_gc): Now EMACS_INT, since a single hash table can
11130 use more than INT_MAX bytes.
11132 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11134 Make it possible to build with GCC-4.6+ -O2 -flto.
11136 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11138 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11140 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11141 Call minibuffer-inactive-mode.
11143 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11145 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11146 Update dependencies.
11148 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11150 * data.c (init_data): Remove code for UTS, this system is not
11153 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11155 Don't force ./temacs to start in terminal mode.
11157 * frame.c (make_initial_frame): Initialize faces in all cases, not
11158 only when CANNOT_DUMP is defined.
11159 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11161 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11163 * dispnew.c (add_window_display_history): Use const for the string
11164 pointer. Remove declaration, not needed.
11166 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11168 Use 'inline', not 'INLINE'.
11169 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11170 * alloc.c, fontset.c (INLINE): Remove.
11171 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11172 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11173 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11174 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11175 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11177 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11179 Make it possible to run ./temacs.
11181 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11182 syms_of_callproc does the same thing. Remove test for
11183 "initialized", do it in the caller.
11184 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11186 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11188 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11189 (read_minibuf): Use get_minibuffer.
11190 (syms_of_minibuf): Use DEFSYM.
11191 (Qmetadata): New var.
11192 * data.c (Qbuffer): Don't make it static.
11193 (syms_of_data): Use DEFSYM.
11195 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11197 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11198 (CCL_CODE_MIN): New macro.
11200 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11202 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11204 * eval.c (Qdebug): Now static.
11205 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11206 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11207 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11209 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11211 * image.c: Various fixes to ImageMagick code comments.
11212 (Fimagemagick_types): Doc fix.
11214 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11216 Minor fixes prompted by GCC 4.6.0 warnings.
11218 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11220 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11221 (x_clipboard_manager_save_all): Move extern decl to ...
11222 * xterm.h: ... here, so that it can be checked for consistency.
11224 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11226 * xselect.c (x_clipboard_manager_save_frame)
11227 (x_clipboard_manager_save_all): New functions.
11228 (Fx_clipboard_manager_save): Lisp function deleted.
11230 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11231 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11233 * xterm.h: Update prototype.
11235 2011-05-28 William Xu <william.xwl@gmail.com>
11237 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11238 exiting (Bug#8239).
11240 2011-05-28 Jim Meyering <meyering@redhat.com>
11242 Avoid a sign-extension bug in crypto_hash_function.
11243 * fns.c (to_uchar): Define.
11244 (crypto_hash_function): Use it to convert some newly-signed
11245 variables to unsigned, to avoid sign-extension bugs. For example,
11246 without this change, (md5 "truc") would evaluate to
11247 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11248 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11249 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11251 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11253 Integer overflow fixes.
11255 * dbusbind.c: Serial number integer overflow fixes.
11256 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11257 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11258 to hold a serial number that is too large for a fixnum.
11259 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11260 Check for serial numbers out of range. Decode any serial number
11261 that was so large that it became a float. (Bug#8722)
11263 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11264 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11265 Use XFASTINT rather than XUINT when numbers are nonnegative.
11266 (xd_append_arg, Fdbus_method_return_internal):
11267 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11268 arguments, check that Lisp number is nonnegative, rather than
11269 silently wrapping negative numbers around. (Bug#8722)
11270 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11273 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11275 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11277 ccl: Add integer overflow checks.
11278 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11279 (IN_INT_RANGE): New macros.
11280 (ccl_driver): Use them to check for integer overflow when
11281 decoding a CCL program. Many of the new checks are whether XINT (x)
11282 fits in int; it doesn't always, on 64-bit hosts. The new version
11283 doesn't catch all possible integer overflows, but it's an
11284 improvement. (Bug#8719)
11286 * alloc.c (make_event_array): Use XINT, not XUINT.
11287 There's no need for unsigned here.
11289 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11290 This follows up to the 2011-05-06 change that substituted uintptr_t
11291 for EMACS_INT. This case wasn't caught back then.
11293 Rework Fformat to avoid integer overflow issues.
11294 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11295 now (part of C89). Include <verify.h>.
11296 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11297 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11298 (Fformat): Avoid the prepass trying to compute sizes; it was only
11299 approximate and thus did not catch overflow reliably. Instead, walk
11300 through the format just once, formatting and computing sizes as we go,
11301 checking for integer overflow at every step, and allocating a larger
11302 buffer as needed. Keep track separately whether the format is
11303 multibyte. Keep only the most-recently calculated precision, rather
11304 than them all. Record whether each argument has been converted to
11305 string. Use EMACS_INT, not int, for byte and char and arg counts.
11306 Support field widths and precisions larger than INT_MAX. Avoid
11307 sprintf's undefined behavior with conversion specifications such as %#d
11308 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11309 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11310 formatting out-of-range floating point numbers with int
11311 formats. (Bug#8668)
11313 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11315 * data.c: Avoid integer truncation in expressions involving floats.
11316 * data.c: Include <intprops.h>.
11317 (arith_driver): When there's an integer overflow in an expression
11318 involving floating point, convert the integers to floating point
11319 so that the resulting value does not suffer from catastrophic
11320 integer truncation. For example, on a 64-bit host (* 4
11321 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11322 Do not rely on undefined behavior after integer overflow.
11324 merge count_size_as_multibyte, parse_str_to_multibyte
11325 * character.c, character.h (count_size_as_multibyte):
11326 Rename from parse_str_to_multibyte; all uses changed.
11327 Check for integer overflow.
11328 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11329 since it's now a duplicate of the other. This is more of
11330 a character than a buffer op, so better that it's in character.c.
11331 * fns.c, print.c: Adjust to above changes.
11333 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11335 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11337 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11339 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11340 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11341 (x_clipboard_manager_save): Now static.
11342 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11344 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11345 (crypto_hash_function): Now static.
11346 Fix pointer signedness problems. Avoid unnecessary initializations.
11348 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11350 * termhooks.h (Vselection_alist): Make it terminal-local.
11352 * terminal.c (create_terminal): Initialize it.
11354 * xselect.c: Support for clipboard managers.
11355 (Vselection_alist): Move to termhooks.h as terminal-local var.
11356 (LOCAL_SELECTION): New macro.
11357 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11358 (symbol_to_x_atom): Remove gratuitous arg.
11359 (x_handle_selection_request, lisp_data_to_selection_data)
11360 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11361 (x_own_selection, x_get_local_selection, x_convert_selection):
11362 New arg, specifying work frame. Use terminal-local Vselection_alist.
11363 (some_frame_on_display): Delete unused function.
11364 (Fx_own_selection_internal, Fx_get_selection_internal)
11365 (Fx_disown_selection_internal, Fx_selection_owner_p)
11366 (Fx_selection_exists_p): New optional frame arg.
11367 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11368 (x_handle_selection_clear): Don't treat other terminals with the
11369 same keyboard specially. Use the terminal-local Vselection_alist.
11370 (x_clear_frame_selections): Use Frun_hook_with_args.
11372 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11374 * xterm.h: Add support for those atoms.
11376 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11378 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11379 (converted_selections, conversion_fail_tag): New global variables.
11380 (x_selection_request_lisp_error): Free the above.
11381 (x_get_local_selection): Remove unnecessary code.
11382 (x_reply_selection_request): Args changed; handle arbitrary array
11383 of converted selections stored in converted_selections.
11384 Separate the XChangeProperty and SelectionNotify steps.
11385 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11386 (x_convert_selection): New function.
11387 (x_handle_selection_event): Simplify.
11388 (x_get_foreign_selection): Don't ignore incoming requests while
11389 waiting for an answer; this will fail when we implement
11390 SAVE_TARGETS, and seems unnecessary anyway.
11391 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11392 (Vx_sent_selection_functions): Doc fix.
11394 2011-05-26 Leo Liu <sdl.web@gmail.com>
11396 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11398 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11400 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11402 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11403 for fringe update if it has periodic bitmap.
11404 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11405 and fringe_bitmap_periodic_p.
11407 * fringe.c (get_fringe_bitmap_data): New function.
11408 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11409 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11410 row. Mark glyph row for fringe update if periodicity changed.
11412 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11413 for fringe update unless it has periodic bitmap.
11415 2011-05-25 Kenichi Handa <handa@m17n.org>
11417 * xdisp.c (get_next_display_element): Set correct it->face_id for
11418 a static composition.
11420 2011-05-24 Leo Liu <sdl.web@gmail.com>
11423 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11425 * fns.c (crypto_hash_function, Fsha1): New function.
11426 (Fmd5): Use crypto_hash_function.
11427 (syms_of_fns): Add Ssha1.
11429 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11431 * gnutls.c: Remove unused macros.
11432 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11433 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11434 Remove macros that are defined and never used.
11435 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11437 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11439 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11440 (Fx_get_selection_internal): Minor cleanup.
11441 (Fx_own_selection_internal): Rename arguments for consistency with
11444 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11446 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11448 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11450 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11452 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11454 * dispnew.c (scrolling_window): Don't exclude the case that the
11455 last enabled row in the desired matrix touches the bottom boundary.
11457 2011-05-21 Glenn Morris <rgm@gnu.org>
11459 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11460 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11461 and add some more files.
11463 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11465 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11466 report_file_error introduced by the change from 2011-05-07.
11468 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11470 * systime.h (Time): Define only if emacs is defined.
11471 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11472 where the include path doesn't have X11/X.h by default. See
11473 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11475 2011-05-20 Kenichi Handa <handa@m17n.org>
11477 * composite.c (find_automatic_composition): Fix previous change.
11479 2011-05-20 Glenn Morris <rgm@gnu.org>
11481 * lisp.mk: New file, split from Makefile.in.
11482 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11483 (shortlisp): Remove.
11484 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11486 2011-05-19 Glenn Morris <rgm@gnu.org>
11488 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11489 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11490 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11491 (lisp): Set the order to that of loadup.el.
11492 (shortlisp): Make it a copy of $lisp.
11493 (SOME_MACHINE_LISP): Remove.
11494 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11495 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11497 2011-05-18 Kenichi Handa <handa@m17n.org>
11499 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11500 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11501 (find_automatic_composition): Mostly rewrite for efficiency.
11503 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11505 * makefile.w32-in: Update dependencies.
11507 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11509 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11510 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11512 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11514 Fix some integer overflow issues, such as string length overflow.
11516 * insdel.c (count_size_as_multibyte): Check for string overflow.
11518 * character.c (lisp_string_width): Check for string overflow.
11519 Use EMACS_INT, not int, for string indexes and lengths; in
11520 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11521 the resulting string length overflows an EMACS_INT; instead,
11522 report a string overflow if no precision given. When checking for
11523 precision exhaustion, use a check that cannot possibly have
11524 integer overflow. (Bug#8675)
11525 * character.h (lisp_string_width): Adjust to new signature.
11527 * alloc.c (string_overflow): New function.
11528 (Fmake_string): Use it. This doesn't change behavior, but saves
11529 a few bytes and will simplify future changes.
11530 * character.c (string_escape_byte8): Likewise.
11531 * lisp.h (string_overflow): New decl.
11533 Fixups, following up to the user-interface timestamp change.
11534 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11535 for UI timestamps, instead of unsigned long.
11536 * msdos.c (mouse_get_pos): Likewise.
11537 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11538 * w32gui.h (Time): Define by including "systime.h" rather than by
11539 declaring it ourselves. (Bug#8664)
11541 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11542 * image.c (clear_image_cache): Likewise.
11544 * term.c (term_mouse_position): Don't assume time_t wraparound.
11546 Be more systematic about user-interface timestamps.
11547 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11548 and sometimes 'EMACS_UINT', to represent these timestamps.
11549 This change causes it to use 'Time' uniformly, as that's what X uses.
11550 This makes the code easier to follow, and makes it easier to catch
11551 integer overflow bugs such as Bug#8664.
11552 * frame.c (Fmouse_position, Fmouse_pixel_position):
11553 Use Time, not unsigned long, for user-interface timestamps.
11554 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11555 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11556 * keyboard.h (last_event_timestamp): Likewise.
11557 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11558 * menu.h (xmenu_show): Likewise.
11559 * term.c (term_mouse_position): Likewise.
11560 * termhooks.h (struct input_event.timestamp): Likewise.
11561 (struct terminal.mouse_position_hook): Likewise.
11562 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11563 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11564 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11565 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11566 what it was before.
11567 * menu.h, termhooks.h: Include "systime.h", for Time.
11569 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11570 Don't assume that the difference between two unsigned long values
11571 can fit into an integer. At this point, we know button_down_time
11572 <= event->timestamp, so the difference must be nonnegative, so
11573 there's no need to cast the result if double-click-time is
11574 nonnegative, as it should be; check that it's nonnegative, just in
11575 case. This bug is triggered when events are more than 2**31 ms
11576 apart (about 25 days). (Bug#8664)
11578 * xselect.c (last_event_timestamp): Remove duplicate decl.
11579 (x_own_selection): Remove needless cast to unsigned long.
11581 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11582 that always fit in int. Use a sentinel instead of a counter, to
11583 avoid a temp and to allay GCC's concerns about possible int overflow.
11584 * frame.h (struct frame): Use int for menu_bar_items_used
11585 instead of EMACS_INT, since it always fits in int.
11587 * menu.c (grow_menu_items): Check for int overflow.
11589 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11591 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11592 Before, the code was not consistent. These values cannot exceed
11593 2**31 - 1 so there's no need to make them unsigned.
11594 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11595 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11596 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11598 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11600 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11601 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11602 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11603 presumably because the widths might not match.
11605 * window.c (size_window): Avoid needless test at loop start.
11607 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11609 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11611 2011-05-12 Drew Adams <drew.adams@oracle.com>
11613 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11615 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11617 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11618 `width' to `bar_area_x' and `bar_area_width', respectively.
11619 (x_scroll_run): Take account of fringe background extension.
11621 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11622 Rename local vars `left' and `width' to `bar_area_x' and
11623 `bar_area_width', respectively.
11624 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11625 background extension.
11627 2011-05-10 Jim Meyering <meyering@redhat.com>
11629 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11631 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11633 * image.c (Finit_image_library): Return t for built-in image types,
11634 like pbm and xbm. (Bug#8640)
11636 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11638 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11640 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11642 * w32console.c (Fset_screen_color): Doc fix.
11643 (Fget_screen_color): New function.
11644 (syms_of_ntterm): Defsubr it.
11646 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11647 unlink the temporary file if Fcall_process didn't create it in the
11649 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11650 child process will be redirected to a file specified with `:file'.
11651 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11652 cue to call_process_cleanup not to close that handle.
11654 2011-05-07 Ben Key <bkey76@gmail.com>
11656 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11657 one of two shell specific rules, either bootstrap-temacs-CMD or
11658 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11659 to the previous implementation of the bootstrap-temacs rule.
11660 The bootstrap-temacs-CMD rule is similar to the previous
11661 implementation of the bootstrap-temacs rule except that it
11662 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11665 These changes, along with some changes to nt/configure.bat,
11666 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11667 earlier fix to add support for --cflags and --ldflags options
11668 that include quotes so that it works whether make uses cmd or
11671 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11673 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11674 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11676 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11677 a string. Handle both cases.
11678 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11679 (Fdbus_register_method): Use Qinvalid_function.
11681 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11683 * makefile.w32-in: Update dependencies.
11684 (LISP_H): Add inttypes.h and stdin.h.
11685 (PROCESS_H): Add unistd.h.
11687 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11689 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11690 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11692 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11694 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11696 * term.c (vfatal): Remove stray call to va_end.
11697 It's not needed and the C Standard doesn't allow it here anyway.
11699 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11700 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11702 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11705 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11707 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11709 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11711 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11713 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11715 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11716 * charset.c (Fdefine_charset_internal): Don't initialize
11717 charset.code_space[15]. The value was garbage, on hosts with
11718 32-bit int (Bug#8600).
11720 * lread.c (read_integer): Be more consistent with string-to-number.
11721 Use string_to_number to do the actual conversion; this avoids
11722 rounding errors and fixes some other screwups. Without this fix,
11723 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11724 (digit_to_number): Move earlier, for benefit of read_integer.
11725 Return -1 if the digit is out of range for the base, -2 if it is
11726 not a digit in any supported base. (Bug#8602)
11728 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11730 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11731 to match comment at start of function. This also removes a
11732 GCC warning about overflow in a 32+64-bit port.
11734 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11736 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11737 Reported by Stefan Monnier in
11738 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11739 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11740 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11742 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11743 (EMACS_UINTPTR): Likewise, with uintptr_t.
11745 * lisp.h: Prefer 64-bit EMACS_INT if available.
11746 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11747 on 32-bit hosts that have 64-bit int, so that they can access
11749 However, temporarily disable this change unless the temporary
11750 symbol WIDE_EMACS_INT is defined.
11752 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11754 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11755 This removes an assumption that EMACS_INT and long are the same
11756 width as pointers. The assumption is true for Emacs porting targets
11757 now, but we want to make other targets possible.
11758 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11759 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11760 In the rest of the code, change types of integers that hold casted
11761 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11762 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11763 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11764 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11765 No need to cast type when ORing.
11766 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11767 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11768 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11769 assume EMACS_INT is the same width as char *.
11770 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11771 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11772 Remove no-longer-needed casts.
11773 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11774 (xg_tool_bar_help_callback, xg_make_tool_item):
11775 Use EMACS_INTPTR to hold an integer
11776 that will be cast to void *; this can avoid a GCC warning
11777 if EMACS_INT is not the same width as void *.
11778 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11779 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11780 (current_message_1, set_message_1):
11781 Use a local to convert to proper width without a cast.
11782 * xmenu.c (dialog_selection_callback): Likewise.
11784 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11785 Also, don't assume VALBITS / RAND_BITS is less than 5,
11786 and don't rely on undefined behavior when shifting a 1 left into
11788 * lisp.h (get_random): Change signature to match.
11790 * lread.c (hash_string): Use size_t, not int, for hash computation.
11791 Normally we prefer signed values; but hashing is special, because
11792 it's better to use unsigned division on hash table sizes so that
11793 the remainder is nonnegative. Also, size_t is the natural width
11794 for hashing into memory. The previous code used 'int', which doesn't
11795 retain enough info to hash well into very large tables.
11796 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11798 * dbusbind.c: Don't possibly lose pointer info when converting.
11799 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11800 Use XPNTR rather than XHASH, so that the high-order bits of
11801 the pointer aren't lost when converting through void *.
11803 * eval.c (Fautoload): Don't double-shift a pointer.
11805 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

11839 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11840 Remove unused parameter `fildes'.
11841 * process.c (read_process_output, send_process): Don't pass it.
11843 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11845 Fix previous change: the library cache is defined in w32.c.
11846 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11847 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

11882 (w32_delayed_load): Move from image.c. When loading a library, record
11883 its filename in the :loaded-from property of the library id.

11885 Initialize and staticpro them.
11886 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11888 * process.c: Include lisp.h before w32.h, not after.
11889 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11890 instead of gnutls_record_check_pending.
11892 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11894 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11896 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11897 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11900 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11902 * xterm.c (x_set_frame_alpha): Do not set property on anything

11939 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11941 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11942 rather than `XVECTOR (FOO)->size'.
11944 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11945 inttypes.h, as a gnulib replacement is used if it not available in
11948 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11950 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11951 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11952 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11954 * coding.c (coding_alloc_by_realloc): Error out if destination
11955 will grow beyond MOST_POSITIVE_FIXNUM.
11956 (decode_coding_emacs_mule): Abort if there isn't enough place in
11957 charbuf for the composition carryover bytes. Reserve an extra

11973 produced by %s or %c overflows available buffer space. (Bug#8545)
11975 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11977 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12012 Improve `doprnt' and its usage. (Bug#8545)
12013 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12014 `format_end'. Remove support for %l as a conversion specifier.
12015 Don't use xrealloc. Improve diagnostics when the %l size modifier
12016 is used. Update the commentary.
12018 * eval.c (verror): Simplify calculation of size_t.
12020 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12023 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12025 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12028 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12030 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12031 This makes this file independent of the recent pseudovector change.
12033 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12035 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12037 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12038 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12039 Remove unused local.
12040 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12042 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12043 GCC 4.6.0 optimizes based on type-based alias analysis.
12044 For example, if b is of type struct buffer * and v of type struct
12045 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12046 != &v->size, and therefore "v->size = 1; b->size = 2; return
12047 v->size;" must therefore return 1. This assumption is incorrect
12048 for Emacs, since it type-puns struct Lisp_Vector * with many other
12049 types. To fix this problem, this patch adds a new type struct
12050 vectorlike_header that documents the constraints on layout of vectors
12051 and pseudovectors, and helps optimizing compilers not get fooled
12052 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12053 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12054 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12056 (XSETPVECTYPE): Rewrite in terms of new macro.
12057 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12058 This is a bit clearer, and further avoids the possibility of
12059 undesirable aliasing.
12060 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12061 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12062 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12063 since Lisp_Subr is a special case (no "next" field).
12064 (ASIZE): Now uses header.size rather than size.
12065 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12066 to avoid the hassle of writing XVECTOR (foo)->header.size.
12067 (struct vectorlike_header): New type.
12068 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12069 object, to help avoid aliasing.
12070 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12071 (SUBRP): Likewise, since Lisp_Subr is a special case.
12072 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12073 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12074 (struct Lisp_Hash_Table): Combine first two members into a single
12075 struct vectorlike_header member. All uses of "size" and "next" members
12076 changed to be "header.size" and "header.next".
12077 * buffer.h (struct buffer): Likewise.
12078 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12079 * frame.h (struct frame): Likewise.
12080 * process.h (struct Lisp_Process): Likewise.
12081 * termhooks.h (struct terminal): Likewise.
12082 * window.c (struct save_window_data, struct saved_window): Likewise.
12083 * window.h (struct window): Likewise.
12084 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12085 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12086 * buffer.c (init_buffer_once): Likewise.
12087 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12089 * process.c (Fformat_network_address): Use local var for size,
12092 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12094 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12095 * data.c (atof): Remove decl; no longer used or needed.
12096 (digit_to_number): Move to lread.c.
12097 (Fstring_to_number): Use new string_to_number function, to be
12098 consistent with how the Lisp reader treats infinities and NaNs.
12099 Do not assume that floating-point numbers represent EMACS_INT
12100 without losing information; this is not true on most 64-bit hosts.
12101 Avoid double-rounding errors, by insisting on integers when
12102 parsing non-base-10 numbers, as the documentation specifies.
12103 * lisp.h (string_to_number): New decl, replacing ...
12104 (isfloat_string): Remove.
12105 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12106 (read1): Do not accept +. and -. as integers; this
12107 appears to have been a coding error. Similarly, do not accept
12108 strings like +-1e0 as floating point numbers. Do not report
12109 overflow for integer overflows unless the base is not 10 which
12110 means we have no simple and reliable way to continue.
12111 Break out the floating-point parsing into a new
12112 function string_to_number, so that Fstring_to_number parses
12113 floating point numbers consistently with the Lisp reader.
12114 (digit_to_number): Move here from data.c. Make it static inline.
12115 (E_CHAR, EXP_INT): Remove, replacing with ...
12116 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12117 (string_to_number): New function, replacing isfloat_string.
12118 This function checks for valid syntax and produces the resulting
12119 Lisp float number too. Rework it so that string-to-number
12120 no longer mishandles examples like "1.0e+". Use strtoumax,
12121 so that overflow for non-base-10 numbers is reported only when
12122 there's no portable and simple way to convert to floating point.
12124 * textprop.c (set_text_properties_1): Rewrite for clarity,
12125 and to avoid GCC warning about integer overflow.
12127 * intervals.h (struct interval): Use EMACS_INT for members
12128 where EMACS_UINT might cause problems. See
12129 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12130 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12131 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12133 (offset_intervals): Tell GCC not to worry about length overflow
12134 when negating a negative length.
12136 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12137 (overrun_check_free): Likewise.
12139 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12140 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12143 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12144 (gnutls_make_error): Rename local to avoid shadowing.
12145 (gnutls_emacs_global_deinit): ifdef out; not used.
12146 (Fgnutls_boot): Use const for pointer to readonly storage.
12147 Comment out unused local. Fix pointer signedness problems.
12149 * lread.c (openp): Don't stuff size_t into an 'int'.
12150 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12151 about possible signed overflow.
12153 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12154 (GDK_KEY_g): Don't define if already defined.
12155 (xg_prepare_tooltip): Avoid pointer signedness problem.
12156 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12158 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12159 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12161 * xfns.c (Fx_window_property): Simplify a bit,
12162 to make a bit faster and to avoid GCC 4.6.0 warning.
12163 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12165 * fns.c (internal_equal): Don't assume size_t fits in int.
12167 * alloc.c (compact_small_strings): Tighten assertion a little.
12169 Replace pEd with more-general pI, and fix some printf arg casts.
12170 * lisp.h (pI): New macro, generalizing old pEd macro to other
12171 conversion specifiers. For example, use "...%"pI"d..." rather
12172 than "...%"pEd"...".
12173 (pEd): Remove. All uses replaced with similar uses of pI.
12174 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12175 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12176 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12177 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12178 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12179 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12180 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12182 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12183 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12184 * print.c (safe_debug_print, print_object): Likewise.
12185 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12187 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12188 avoiding the 0 flag, which is not portable.
12189 * process.c (Fmake_network_process): Use pI to avoid cast.
12190 * region-cache.c (pp_cache): Likewise.
12191 * xdisp.c (decode_mode_spec): Likewise.
12192 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12193 behavior on 64-bit hosts with printf arg.
12194 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12195 (x_stop_queuing_selection_requests): Likewise.
12196 (x_get_window_property): Don't truncate byte count to an 'int'
12199 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12200 here, since it parses constructs like leading '-' and spaces,
12201 which are not wanted; and it overflows with large numbers.
12202 Instead, simply match F[0-9]+, which is what is wanted anyway.
12204 * alloc.c: Remove unportable assumptions about struct layout.

12208 plus offsetof, to remove unportable assumptions about struct layout.
12209 These assumptions hold on all porting targets that I know of, but
12210 they are not guaranteed, they're easy to remove, and removing them
12211 makes further changes easier.
12213 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12214 This doesn't fix a bug but makes the code clearer.
12215 (string_overrun_cookie): Now const. Use initializers that

12218 can cause Emacs to crash when string overrun checking is enabled.
12219 (allocate_buffer): Don't assume sizeof (struct buffer) is a

12258 supported by the function. Use SAFE_ALLOCA instead of always
12261 * eval.c (verror): Don't limit the buffer size at size_max-1, that

12389 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12390 to `error' in error message about FINAL_CHAR argument. Make sure
12391 FINAL_CHAR is a character, and use %c when it is passed as
12392 argument to `error'.
12394 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12396 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12398 * w32.c: Include <time.h>.

12462 * dispextern.h (struct redisplay_interface): Rename param
12463 to avoid shadowing.

12582 ns_descriptor_to_entity that were caused by using free to
12583 deallocate memory blocks that were allocated by xmalloc (via
12584 xstrdup). This caused Emacs to crash when compiled with
12585 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12586 --enable-checking=xmallocoverrun). xfree is now used to
12587 deallocate these memory blocks.

12604 (emacs_read, emacs_write): Use it.
12605 * process.c (send_process): Adjust to the new signatures of
12606 emacs_write and emacs_gnutls_write. Do not attempt to store

13092 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13094 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13095 argument, local variables, and return value.
13097 * lisp.h: Update prototypes of emacs_write and emacs_read.
13099 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13101 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13103 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13105 Fix more problems found by GCC 4.6.0's static checks.
13107 * xdisp.c (vmessage): Use a better test for character truncation.
13109 * charset.c (load_charset_map): <, not <=, for optimization,
13110 and to avoid potential problems with integer overflow.
13111 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13112 * casetab.c (set_identity, shuffle): Likewise.
13113 * editfns.c (Fformat): Likewise.
13114 * syntax.c (skip_chars): Likewise.
13116 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13117 This also lets GCC 4.6.0 generate slightly better loop code.
13119 * callint.c (Fcall_interactively): <, not <=, for optimization.
13120 (Fcall_interactively): Count the number of arguments produced,
13121 not the number of arguments given. This is simpler and lets GCC
13122 4.6.0 generate slightly better code.
13124 * ftfont.c: Distingish more carefully between FcChar8 and char.
13125 The previous code passed unsigned char * to a functions like
13126 strlen and xstrcasecmp that expect char *, which does not
13127 conform to the C standard.
13128 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13129 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13130 char * when the C standard requires it.
13132 * keyboard.c (read_char): Remove unused var.
13134 * eval.c: Port to Windows vsnprintf (Bug#8435).
13135 Include <limits.h>.
13136 (SIZE_MAX): Define if the headers do not.
13137 (verror): Do not give up if vsnprintf returns a negative count.
13138 Instead, grow the buffer. This ports to Windows vsnprintf, which
13139 does not conform to C99. Problem reported by Eli Zaretskii.
13140 Also, simplify the allocation scheme, by avoiding the need for
13141 calling realloc, and removing the ALLOCATED variable.
13143 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13145 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13146 But keep the doprint source code for now, as we might revamp it
13147 and use it again (Bug#8435).
13148 * lisp.h (doprnt): Remove.
13149 * Makefile.in (base_obj): Remove doprnt.o.
13150 * deps.mk (doprnt.o): Remove.
13152 error: Print 32- and 64-bit integers portably (Bug#8435).
13153 Without this change, on typical 64-bit hosts error ("...%d...", N)
13154 was used to print both 32- and 64-bit integers N, which relied on
13155 undefined behavior.
13156 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13157 * lisp.h (error, verror): Mark as printf-like functions.
13158 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13159 Report overflow in size calculations when allocating printf buffer.
13160 Do not truncate output string at its first null byte.
13161 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13162 Truncate the output at a character boundary, since vsnprintf does not
13164 * charset.c (check_iso_charset_parameter): Convert internal
13165 character to string before calling 'error', since %c now has the
13167 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13168 overflow when computing char to be passed to 'error'. Do not
13169 pass Lisp_Object to 'error'; pass the integer instead.
13170 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13171 formatted with plain %d.
13173 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13175 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13177 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13179 * xterm.c (x_catch_errors): Remove duplicate declaration.
13181 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13183 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13185 2011-04-10 Jim Meyering <meyering@redhat.com>
13187 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13188 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13189 return ssize_t not "int", and use size_t as the buffer length.
13190 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13191 * gnutls.h: Update declarations.
13192 * process.c (read_process_output): Use ssize_t, to match.
13193 (send_process): Likewise.
13195 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13197 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13199 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13201 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13202 Use unsigned char, to match FcChar8 type definition.
13204 * xterm.c (handle_one_xevent):
13205 * xmenu.c (create_and_show_popup_menu):
13206 * xselect.c (x_decline_selection_request)
13207 (x_reply_selection_request): Avoid type-punned deref of X events.
13209 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13211 Fix some uses of `int' instead of EMACS_INT.
13212 * search.c (string_match_1, fast_string_match)
13213 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13214 (scan_buffer, find_next_newline_no_quit)
13215 (find_before_next_newline, search_command, Freplace_match)
13216 (Fmatch_data): Make some `int' variables be EMACS_INT.
13218 * xdisp.c (display_count_lines): 3rd argument and return value now
13219 EMACS_INT. All callers changed.
13220 (pint2hrstr): Last argument is now EMACS_INT.
13222 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13223 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13224 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13225 (decode_coding_utf_16, decode_coding_emacs_mule)
13226 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13227 (decode_coding_ccl, decode_coding_charset)
13228 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13229 (decode_coding_iso_2022, decode_coding_emacs_mule)
13230 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13231 <char_offset, last_offset>: Declare EMACS_INT.
13232 (encode_coding_utf_8, encode_coding_utf_16)
13233 (encode_coding_emacs_mule, encode_invocation_designation)
13234 (encode_designation_at_bol, encode_coding_iso_2022)
13235 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13236 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13238 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13239 (encode_invocation_designation): Last argument P_NCHARS is now
13241 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13242 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13244 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13247 * ccl.c (Fccl_execute_on_string): Declare some variables
13250 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13252 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13254 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13256 * process.c (Fformat_network_address): Doc fix.
13258 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13260 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13262 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13264 * keyboard.c (read_char): Call Lisp function help-form-show,
13265 instead of using internal_with_output_to_temp_buffer.
13266 (Qhelp_form_show): New var.
13267 (syms_of_keyboard): Use DEFSYM macro.
13269 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13271 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13273 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13275 * process.c (Flist_processes): Remove to Lisp.
13276 (list_processes_1): Delete.

13280 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13282 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13284 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13286 Fix more problems found by GCC 4.6.0's static checks.
13288 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13290 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13292 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13294 * xdisp.c (vmessage): Mark as a printf-like function.
13296 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13298 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13300 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13301 printf-like functions.

13303 to system-supplied API.
13305 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13307 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13308 This avoids several warnings with gcc -Wstrict-overflow.
13309 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13310 directly, rather than having caller test rule sign. This avoids
13311 some unnecessary tests.
13312 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13313 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13314 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13316 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13317 (xfont_open): Avoid unnecessary tests.
13319 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13321 * composite.h, composite.c (composition_gstring_put_cache):
13322 Use EMACS_INT, not int, for length.

13325 breaking out part of COMPOSITION_DECODE_RULE.
13326 (COMPOSITION_DECODE_RULE): Use it.

13328 by using the new macro.
13330 * textprop.c (set_text_properties_1): Change while to do-while,
13331 since the condition is always true at first.
13333 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13334 (interval_deletion_adjustment): Return unsigned value.
13337 * process.c (list_processes_1, create_pty, read_process_output):

13349 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13350 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13351 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13353 * print.c (print_error_message): Avoid int overflow.
13355 * font.c (font_list_entities): Redo for clarity,
13356 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13358 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13359 (font_score): Avoid potential overflow in diff calculation.
13361 * fns.c (substring_both): Remove var that is set but not used.
13362 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13364 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13366 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13367 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13368 can always succeed if overflow has undefined behavior.
13370 * search.c (boyer_moore, wordify): Remove vars set but not used.
13371 (wordify): Omit three unnecessary tests.
13373 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13374 All callers changed. This avoids the need for an unused var.
13376 * casefiddle.c (casify_region): Remove var that is set but not used.

13386 Check for integer overflow on size calculations.
13388 * buffer.c (Fprevious_overlay_change): Remove var that is set
13391 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13392 Remove vars that are set but not used.
13393 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13394 (timer_check_2): Mark vars as initialized.
13396 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13398 * image.c (lookup_image): Remove var that is set but not used.
13399 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13401 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13402 that are set but not used.
13404 * xfns.c (make_invisible_cursor): Don't return garbage
13405 if XCreateBitmapFromData fails (Bug#8410).
13407 * xselect.c (x_get_local_selection, x_handle_property_notify):
13408 Remove vars that are set but not used.
13410 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

13420 (map_tty_color) [!defined MSDOS]: Likewise.
13422 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13424 * coding.c: Remove vars that are set but not used.
13425 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13426 All callers changed.

13428 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13429 (decode_coding_charset): Remove vars that are set but not used.
13431 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13432 that is set but not used.
13434 * print.c (print_object): Remove var that is set but not used.
13436 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13437 The gnulib version avoids calling malloc in the usual case,
13438 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13439 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13440 * filelock.c (current_lock_owner): Likewise.
13441 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

13445 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13446 ../lib/careadlinkat.h.
13448 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13450 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13451 first non-nil return value).

13465 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13466 and thereabouts. All callers changed.
13467 (get_per_char_metric): Remove parameter `f', unused since
13468 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13551 Limit scrolling to 100 screen lines.
13552 (redisplay_window): Even when falling back on "recentering",
13553 position point in the window according to scroll-conservatively,
13554 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13556 (try_scrolling): When point is above the window, allow searching
13557 as far as scroll_max, or one screenful, to compute vertical
13558 distance from PT to the scroll margin position. This prevents
13559 try_scrolling from unnecessarily failing when
13560 scroll-conservatively is set to a value slightly larger than the
13561 window height. Clean up the case of PT below the margin at bottom
13562 of window: scroll_max can no longer be INT_MAX. When aggressive
13563 scrolling is in use, don't let point enter the opposite scroll
13564 margin as result of the scroll.
13565 (syms_of_xdisp) <scroll-conservatively>: Document the
13566 threshold of 100 lines for never-recentering scrolling.
13568 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13570 * dispextern.h (move_it_by_lines):
13571 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13572 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13573 (message_log_check_duplicate): Remove parameters `prev_bol' and
13574 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13575 (redisplay_internal): Remove parameter `preserve_echo_area',
13576 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13578 * indent.c (Fvertical_motion):
13579 * window.c (window_scroll_pixel_based, Frecenter):
13580 Don't pass `need_y_p' to `move_it_by_lines'.
13582 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13584 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13585 steal a few bits to be more compact.
13586 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13587 Remove unneeded casts.
13589 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13591 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13593 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13594 binding" message (bug#7967).
13596 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13598 Fix more problems found by GCC 4.6.0's static checks.
13600 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13601 Remove unused local var.
13603 * editfns.c (Fmessage_box): Remove unused local var.
13605 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13606 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13607 Omit unused local vars.
13608 * window.c (shrink_windows): Omit unused local var.
13609 * menu.c (digest_single_submenu): Omit unused local var.
13610 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13611 Omit unused local var.
13613 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13614 Don't assume string length fits in int.
13615 (keyremap_step, read_key_sequence): Use size_t for sizes.
13616 (read_key_sequence): Don't check last_real_key_start redundantly.
13618 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13619 instead of alloca (Bug#8344).
13621 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13622 (Fbacktrace_frame): Don't assume nframes fits in int.
13624 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13626 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13629 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13631 * cm.c (calccost): Turn while-do into do-while, for clarity.
13633 * keyboard.c (syms_of_keyboard): Use the same style as later
13634 in this function when indexing through an array. This also
13635 works around GCC bug 48267.
13637 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13639 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13641 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13642 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13644 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13645 This avoids undefined behavior on integer overflow, and is a bit
13646 more convenient anyway since it is compared to a size_t variable.
13648 Variadic C functions now count arguments with size_t, not int.
13649 This avoids an unnecessary limitation on 64-bit machines, which
13650 caused (substring ...) to crash on large vectors (Bug#8344).
13651 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13652 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13656 * editfns.c (general_insert_function): Likewise.
13657 * eval.c (struct backtrace.nargs, interactive_p)
13658 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13659 (funcall_lambda, mark_backtrace): Likewise.
13660 * fns.c (concat): Likewise.
13661 * frame.c (x_set_frame_parameters): Likewise.
13662 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13663 0 if not found, not -1. All callers changed.
13665 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13666 (stack_copy_size): Now size_t, not int.
13667 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13669 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13671 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13672 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13673 All callers changed.
13675 * lisp.h (multibyte_char_to_unibyte):
13676 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13677 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13678 * character.h (CHAR_TO_BYTE8):
13679 * cmds.c (internal_self_insert):
13680 * editfns.c (general_insert_function):
13681 * keymap.c (push_key_description):
13682 * search.c (Freplace_match):
13683 * xdisp.c (message_dolog, set_message_1): All callers changed.
13685 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13687 * keyboard.c (safe_run_hook_funcall): New function.
13688 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13689 don't set the hook to nil, but remove the offending function instead.
13690 (Qcommand_hook_internal): Remove, unused.
13691 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13692 Vcommand_hook_internal.
13694 * eval.c (enum run_hooks_condition): Remove.
13695 (funcall_nil, funcall_not): New functions.
13696 (run_hook_with_args): Call each function through a `funcall' argument.
13697 Remove `cond' argument, now redundant.
13698 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13699 (Frun_hook_with_args_until_failure): Adjust accordingly.
13700 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13702 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13704 * dispextern.h (string_buffer_position): Remove declaration.
13706 * print.c (strout): Remove parameter `multibyte', unused since
13707 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13709 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13710 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13711 All callers changed.
13713 * w32.c (_wsa_errlist): Use braces for struct initializers.
13715 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13716 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13717 All callers changed.
13718 (string_buffer_position): Likewise. Also, make static (it's never
13719 used outside xdisp.c).

13723 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13724 All callers changed.
13726 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13728 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13734 (ns_update_auto_hide_menu_bar): New functions.
13735 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

13739 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
13741 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

13748 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
13749 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
13750 Replace SIGTYPE with void everywhere.
13751 * s/usg5-4-common.h (SIGTYPE): Remove definition.

13754 2011-03-26 Eli Zaretskii <eliz@gnu.org>
13756 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
13757 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13759 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13761 * w32.c (read_unc_volume): Use parameter `henum', instead of
13762 global variable `wget_enum_handle'.
13764 * keymap.c (describe_vector): Remove parameters `indices' and
13765 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

13776 * w32menu.c (w32_menu_display_help):
13777 * xmenu.c (show_help_event, menu_help_callback):
13778 Adjust calls to `show_help_echo'.
13780 * gtkutil.c (xg_maybe_add_timer):
13781 * keyboard.c (readable_events):
13782 * process.c (wait_reading_process_output):
13783 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
13785 * insdel.c (adjust_markers_gap_motion):
13786 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

13860 2011-03-23 Julien Danjou <julien@danjou.info>
13862 * term.c (Fsuspend_tty, Fresume_tty):
13863 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13864 * window.c (temp_output_buffer_show):

13870 * cmds.c (internal_self_insert):
13871 * callint.c (Fcall_interactively):
13872 * buffer.c (Fkill_all_local_variables):
13873 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13875 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13876 unconditionally since it does the check itself.
13878 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13880 Fix more problems found by GCC 4.5.2's static checks.
13882 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13883 the first time through the loop, since we know p0 < p1 then.
13884 This also avoids a gcc -Wstrict-overflow warning.
13886 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13887 leading to a memory leak, possible in functions like
13888 load_charset_map_from_file that can allocate an unbounded number
13889 of objects (Bug#8318).
13891 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13892 that could (at least in theory) be that large.
13894 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13895 This is less likely to overflow, and avoids undefined behavior if
13896 overflow does occur. All callers changed. Use strtoul to scan
13897 for the unsigned long integer.
13898 (pint2hrstr): Simplify and tune code slightly.
13899 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13901 * scroll.c (do_scrolling): Work around GCC bug 48228.
13902 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13904 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13905 This also avoids a warning with gcc -Wstrict-overflow.
13906 (validate_x_resource_name): Simplify count usage.
13907 This also avoids a warning with gcc -Wstrict-overflow.
13909 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13912 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13914 * process.c (Fmake_network_process): Use socklen_t, not int,
13915 where POSIX says socklen_t is required in portable programs.
13916 This fixes a porting bug on hosts like 64-bit HP-UX, where
13917 socklen_t is wider than int (Bug#8277).
13918 (Fmake_network_process, server_accept_connection):
13919 (wait_reading_process_output, read_process_output):
13922 * process.c: Rename or move locals to avoid shadowing.
13923 (list_processes_1, Fmake_network_process):
13924 (read_process_output_error_handler, exec_sentinel_error_handler):
13925 Rename or move locals.
13926 (Fmake_network_process): Define label "retry_connect" only if needed.
13927 (Fnetwork_interface_info): Fix pointer signedness.
13928 (process_send_signal): Add cast to avoid pointer signedness problem.
13929 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13930 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13932 Make tparam.h and terminfo.c consistent.
13933 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13934 Include tparam.h instead, since it declares them.
13935 * cm.h (PC): Remove extern decl; tparam.h now does this.
13936 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13937 * terminfo.c: Include tparam.h, to check interfaces.
13938 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13939 (tparam): Adjust signature to match interface in tparam.h;
13940 this removes some undefined behavior. Check that outstring and len
13941 are zero, which they always are with Emacs.
13942 * tparam.h (PC, BC, UP): New extern decls.
13944 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13945 (xftfont_open): Rename locals to avoid shadowing.
13947 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13948 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13949 (OTF_TAG_SYM): Omit macro if not needed.
13950 (ftfont_list): Remove unused local.
13951 (get_adstyle_property, ftfont_pattern_entity):
13952 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13953 Rename locals to avoid shadowing.
13955 * xfont.c (xfont_list_family): Mark var as initialized.
13957 * xml.c (make_dom): Now static.
13959 * composite.c (composition_compute_stop_pos): Rename local to
13961 (composition_reseat_it): Remove unused locals.
13962 (find_automatic_composition, composition_adjust_point): Likewise.
13963 (composition_update_it): Mark var as initialized.
13964 (find_automatic_composition): Mark vars as initialized,
13965 with a FIXME (Bug#8290).
13967 character.h: Rename locals to avoid shadowing.
13968 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13969 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13970 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13971 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13972 to avoid shadowing.
13974 * textprop.c (property_change_between_p): Remove; unused.
13976 * intervals.c (interval_start_pos): Now static.
13978 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13980 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13981 Rename locals to avoid shadowing.
13983 * sound.c (wav_play, au_play, Fplay_sound_internal):
13984 Fix pointer signedness.

13991 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13993 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13994 clobbering (Bug#8298).
13995 * sysdep.c (sys_subshell): Likewise.
13996 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13998 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13999 This should get cleaned up, so that child_setup has the
14000 same signature on all platforms.
14002 * callproc.c (call_process_cleanup): Now static.
14003 (relocate_fd): Rename locals to avoid shadowing.
14005 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

14133 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14134 some of which prompt warnings from gcc -Wbad-function-cast.
14135 (Fformat_time_string, Fencode_time, Finsert_char):

14164 (Fmemory_limit): Cast sbrk's returned value to char *.
14166 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14169 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14171 Use functions, not macros, for up- and down-casing (Bug#8254).
14172 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14173 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14174 to use the following functions instead of these macros.
14175 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14176 EMACS_INT, since callers assume the returned value fits in int.
14177 (upcase1): Likewise, for UPCASE_TABLE.
14178 (uppercasep, lowercasep, upcase): New static inline functions.
14179 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14189 (regex_compile, re_match_2_internal): Mark locals as initialized.
14190 (RETALLOC_IF): Define only if needed.
14191 (WORDCHAR_P): Likewise. This one is never needed, but is used
14192 only in a comment talking about a compiler bug, so put inside
14193 the #if 0 of that comment.
14194 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14195 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

14221 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14222 New macros, so that the caller can use some names other than
14223 gcpro1, gcpro2, etc.
14224 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14226 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14227 argument, for consistency with GCPRO2_VAR, etc: it is now the
14228 prefix of the variable, not the variable itself. All uses
14230 * dired.c (directory_files_internal, file_name_completion):
14231 Rename locals to avoid shadowing.
14233 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14234 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14235 dired.c's scmp function, had undefined behavior.
14236 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14237 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14238 * buffer.h: ... to here, because these macros use current_buffer,
14239 and the new implementation with inline functions needs to have
14240 current_buffer in scope now, rather than later when the macros
14242 (downcase, upcase1): New static inline functions.
14243 (DOWNCASE, UPCASE1): Reimplement using these functions.
14244 This avoids undefined behavior in expressions like
14245 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14246 from race conditions in accessing the global variables
14247 case_temp1 and case_temp2.
14248 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14249 * lisp.h (case_temp1, case_temp2): Remove their decls.
14250 * character.h (ASCII_CHAR_P): Move from here ...
14251 * lisp.h: ... to here, so that the inline functions mentioned
14252 above can use them.
14254 * dired.c (directory_files_internal_unwind): Now static.
14256 * fileio.c (file_name_as_directory, directory_file_name):

14259 (file_name_as_directory): Use const pointers when appropriate.
14260 (Fexpand_file_name): Likewise. In particular, newdir might
14261 point at constant storage, so make it a const pointer.
14262 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14263 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14265 (Fset_file_times, Finsert_file_contents, auto_save_error):

14270 to avoid shadowing.
14272 * marker.c (bytepos_to_charpos): Remove; unused.
14274 * lisp.h (verify_bytepos, count_markers): New decls,
14275 so that gcc does not warn that these functions aren't declared.
14277 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14278 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14279 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14280 (copy_text): Remove unused local var.
14282 * filelock.c (within_one_second): Now static.
14283 (lock_file_1): Rename local to avoid shadowing.
14285 * buffer.c (fix_overlays_before): Mark locals as initialized.
14286 (fix_start_end_in_overlays): Likewise. This function should be
14287 simplified by using pointers-to-pointers, but that's a different
14289 (switch_to_buffer_1): Now static.
14290 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14291 (report_overlay_modification): Rename locals to avoid shadowing.
14293 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14294 Fix pointer signedness issue.
14295 (sys_subshell): Mark local as volatile if checking for lint,
14296 to suppress a gcc -Wclobbered warning that does not seem to be right.
14297 (MAXPATHLEN): Define only if needed.
14299 * process.c (serial_open, serial_configure): Move decls from here ...
14300 * systty.h: ... to here, so that they can be checked.
14302 * fns.c (get_random, seed_random): Move extern decls from here ...
14303 * lisp.h: ... to here, so that they can be checked.
14305 * sysdep.c (reset_io): Now static.
14306 (wait_for_termination_signal): Remove; unused.
14308 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14309 (copy_keymap_item, append_key, push_text_char_description):
14311 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14312 (DENSE_TABLE_SIZE): Remove; unused.
14313 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14314 (describe_map_tree):
14315 Rename locals to avoid shadowing.
14317 * keyboard.c: Declare functions static if they are not used elsewhere.

14402 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
14403 These macros can no longer be used for assignment.
