77 * xterm.c (updating_frame): Remove decl of nonexistent object.
79 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)

135 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
136 more than one grapheme cluster passed to the shaper: compute the
137 offset adjustment values separately for each cluster. (Bug#11860)
139 * image.c: Restore mistakenly removed inclusion of w32.h. Without
140 it, GCC doesn't see prototypes of w32_delayed_load, and complains

199 window system declarations.
201 * frame.h: Move common functions here: set_frame_menubar,
202 x_set_window_size, x_sync, x_get_focus_frame,
203 x_set_mouse_position, x_set_mouse_pixel_position,
204 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

290 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
291 Add window_closed and button_values. Add void as return value for
292 add(Button|String|Split). addButton takes int instead of Lisp_Object.

477 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
478 * window.h (decode_valid_window):
481 * character.c, charset.c, chartab.c: Use bool for booleans.
482 * character.c (lisp_string_width, string_count_byte8)
483 (string_escape_byte8):
484 * charset.c (charset_map_loaded, load_charset_map, read_hex):
485 (load_charset_map_from_file, map_charset_chars)
486 (Fdefine_charset_internal, define_charset_internal)
487 (Fdeclare_equiv_charset, find_charsets_in_text)
488 (Ffind_charset_region, char_charset, Fiso_charset):
489 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
490 (sub_char_table_set, sub_char_table_set_range)
491 (char_table_set_range, optimize_sub_char_table)
492 (map_sub_char_table):
493 Use bool for boolean.
494 * character.c (str_to_unibyte): Omit last boolean argument; it was
495 always 0. All callers changed.
496 * character.h, charset.h: Adjust to match previous changes.
497 * character.h (char_printable_p): Remove decl of nonexistent function.
498 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
499 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
500 are all boolean, so make them single-bit bitfields.
502 * lisp.h (ASET): Remove attempt to detect side effects.
503 It was meant to be temporary and it often doesn't work,
504 because when IDX has side effects the behavior of IDX==IDX
505 is undefined. See Stefan Monnier in
506 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
508 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
510 * lisp.h (functionp): New function (extracted from Ffunctionp).
512 * eval.c (Ffunctionp): Use it.
514 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
516 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
517 as that's faster and simpler than static storage. Don't bother
518 with the g_main_context_query overhead if g_main_context_pending
519 says no events are pending.
520 (gfds, gfds_size): Remove these static vars.
521 (xgselect_initialize): Remove; no longer needed.
522 All uses and decls removed.
524 * emacs.c (fatal_error_signal_hook): Remove.
525 All uses removed. This leftover from old code was always 0.
527 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
528 * casefiddle.c (casify_object, casify_region):
529 * casetab.c (set_case_table):
530 * category.c, category.h (word_boundary_p):
531 * category.h (CHAR_HAS_CATEGORY):
532 Use bool for booleans, instead of int.
534 2012-08-25 Eli Zaretskii <eliz@gnu.org>
536 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
538 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
540 On assertion failure, print backtrace if available.
541 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
542 (die) [ENABLE_CHECKING]: Print a backtrace if available.
543 * Makefile.in (LIB_EXECINFO): New macro.
546 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
547 * bytecode.c (exec_byte_code):
548 * callint.c (check_mark, Fcall_interactively):
549 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
550 (getenv_internal, sync_process_alive, call_process_exited):
551 * lisp.h (USE_SAFE_ALLOCA):
552 Use bool for booleans, instead of int.
553 * lisp.h, process.h: Adjust prototypes to match above changes.
554 * callint.c (Fcall_interactively): Don't assume the mark's
555 offset fits in 'int'.
557 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
559 * buffer.c, buffer.h: Use bool for boolean.
560 * buffer.c (reset_buffer_local_variables)
561 (buffer_lisp_local_variables, Fset_buffer_modified_p)
562 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
563 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
564 (overlay_touches_p, overlay_strings, Foverlay_put)
565 (report_overlay_modification, call_overlay_mod_hooks):
566 (mmap_enlarge, mmap_set_vars):
567 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
568 Use bool for booleans, instead of int.
569 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
570 since the 1-or-0 return value is always ignored anyway.
571 (mmap_initialized_p):
572 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
573 * buffer.h, lisp.h: Adjust prototypes to match above changes.
575 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
577 * bidi.c: Use bool for boolean.
578 This is a bit more readable, and makes the text segment of bidi.o
579 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
580 Presumably it's faster too.
581 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
583 (bidi_cache_find_level_change, bidi_cache_iterator_state)
584 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
585 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
586 (bidi_explicit_dir_char, bidi_level_of_next_char)
587 (bidi_find_other_level_edge, bidi_move_to_visually_next):
588 Use bool for booleans, instead of int.
589 * dispextern.h (bidi_init_it, bidi_paragraph_init)
590 (bidi_unshelve_cache): Adjust decls to match code.
592 2012-08-23 Martin Rudalics <rudalics@gmx.at>
594 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
597 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
599 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
600 * atimer.h: Include <stdbool.h>.
602 2012-08-22 Dan Nicolaescu <dann@gnu.org>
604 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
605 compile time tests instead of run time tests on systems that do
607 (FRAME_MAC_P): Remove leftover from deleted code.
608 * frame.c (syms_of_frame): Remove leftover from deleted code.
610 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
612 * nsterm.m (insertText:): Don't clear modifiers if code is space.
614 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
616 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
617 Otherwise, the compiler complains about (A?B:C) where B is void
618 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
619 (fontset_add): Return void, for FONTSET_ADD.
621 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
623 * alloc.c: Use bool for booleans.
624 (gc_in_progress, abort_on_gc)
625 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
626 (dont_register_blocks) [GC_MALLOC_CHECK]:
627 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
628 (check_string_bytes, make_specified_string, memory_full)
629 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
630 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
631 (mark_stack, valid_pointer_p, make_pure_string)
632 (Fgarbage_collect, survives_gc_p, gc_sweep):
633 Use bool for booleans, instead of int.
634 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
636 * alloc.c (PURE_POINTER_P):
637 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
638 * editfns.c (Fformat):
639 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
641 * fns.c (sweep_weak_table):
642 * lisp.h (suppress_checking, push_message, survives_gc_p)
643 (make_pure_string, gc_in_progress, abort_on_gc):
644 * lread.c (readchar, read1):
645 * print.c (Fprin1_to_string):
646 * xdisp.c (push_message):
647 Use bool for booleans affected directly or indirectly by
650 Make recently-introduced setters macros.
651 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
652 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
653 (set_fontset_default, set_fontset_fallback): Rename from their
654 upper-case counterparts, and make them functions rather than macros.
655 This is more consistent with the other recently-introduced setters.
656 These don't need to be inline, since they're local.
658 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
660 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
661 the loop (Bug#12247).
663 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
665 * lisp.h (vcopy): Use memcpy rather than our own loop.
666 This fixes a performance regression introduced by the recent
667 addition of vcopy. This means 'vcopy' will need to be modified
668 for a copying collector, but that's OK. Also, tighten the
669 checking in the assertion.
671 2012-08-21 Eli Zaretskii <eliz@gnu.org>
673 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
674 components for RTL text (Bug#11860). Adjust X-OFFSET of each
675 non-base glyph for the width of the base character, according to
676 what x_draw_composite_glyph_string_foreground expects.
677 Generate WADJUST value according to composition_gstring_width's
678 expectations, to produce correct width of the composed character.
679 Reverse the sign of the DU offset produced by ScriptPlace.
681 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
683 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
685 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
687 Avoid direct writes to contents member of struct Lisp_Vector.
688 * lisp.h (vcopy): New function to copy data into vector.
689 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
690 * fns.c (Ffillarray): Use ASET.
691 * keyboard.c (timer_check_2): Use AREF and ASET.
692 (append_tool_bar_item, Frecent_keys): Use vcopy.
693 * lread.c (read_vector): Use ASET.
694 * msdos.c (Frecent_doskeys): Use vcopy.
695 * xface.c (Finternal_copy_lisp_face): Use vcopy.
696 (Finternal_merge_in_global_face): Use ASET and vcopy.
697 * xfont.c (xfont_list_pattern): Likewise.
699 2012-08-21 Martin Rudalics <rudalics@gmx.at>
701 * window.c (Fwindow_point): For the selected window always return
702 the position of its buffer's point.
703 (Fset_window_point): For the selected window always go in its
704 buffer to the specified position.
706 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
708 Setter macros for fontsets.
709 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
710 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
711 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
714 2012-08-20 Glenn Morris <rgm@gnu.org>
716 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
717 Don't assume that `ln -f' works.
719 2012-08-20 Eli Zaretskii <eliz@gnu.org>
721 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
722 and later about non-assignments with no effect. See discussion at
723 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
726 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
728 Inline setter functions for Lisp_Objects slots of struct specbinding.
729 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
732 2012-08-20 Martin Rudalics <rudalics@gmx.at>
734 * window.c (select_window): Always make selected window's buffer
737 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
739 Use AREF and ASET for docstrings of category tables.
740 * category.h (CATEGORY_DOCSTRING): Use AREF.
741 (SET_CATEGORY_DOCSTRING): Use ASET.
742 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
744 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
746 Inline setter functions for hash table members.
747 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
748 (set_hash_hash, set_hash_index): Rename with _slot suffix.
749 (set_hash_key_and_value, set_hash_index, set_hash_next)
750 (set_hash_hash): New functions.
751 * charset.c, fns.c: Adjust users.
753 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
755 Inline getter and setter functions for per-buffer values.
756 * buffer.h (per_buffer_default, set_per_buffer_default)
757 (per_buffer_value, set_per_buffer_value): New functions.
758 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
759 * buffer.c, data.c: Adjust users.
761 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
763 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
765 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
767 Rely on <config.h> + <unistd.h> to declare 'environ',
768 as gnulib does this if the system doesn't.
769 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
770 Remove declaration. MS-Windows declares it on stdlib.h which is
771 included by conf_post.h.
772 * emacs.c (environ) [DOUG_LEA_MALLOC]:
773 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
774 * vm-limit.c: Include <unistd.h>, for 'environ'.
776 * unexaix.c, unexcoff.c: Include "mem-limits.h".
777 (start_of_data): Remove decl; mem-limits.h provides it.
779 * xdisp.c (handle_invisible_prop): Make it a bit faster
780 and avoid a gcc -Wmaybe-uninitialized diagnostic.
782 2012-08-19 Chong Yidong <cyd@gnu.org>
784 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
787 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
789 * .gdbinit: Use call instead of set when calling a function in the
792 * data.c (set_internal): Don't use set_blv_found.
793 (Fkill_local_variable): Likewise.
795 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
797 * nsfont.m (ns_ascii_average_width): Ensure the string
798 ascii_printable is initialized with a null-terminated character
799 array. Otherwise, it can contain undesired extra characters.
801 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
803 port new setting code to Sun C 5.8 2005/10/13
804 * chartab.c, lisp.h (char_table_set, char_table_set_range):
805 Return void, not Lisp_Object. Otherwise, the compiler
806 complains about (A?B:C) where B is void and C is Lisp_Object
807 when compiling CHAR_TABLE_SET, due to the recent change to
808 the API of sub_char_table_set_contents.
810 2012-08-18 Chong Yidong <cyd@gnu.org>
812 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
813 for the string case (Bug#3874).
815 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
817 * buffer.h (BSET): Remove (Bug#12215).

1640 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
1641 * w32.c (init_environment): Change the default values of many
1642 environment variables in dflt_envvars[] to NULL, to avoid pushing
1643 them into environment when they were not already defined.
1644 Remove the code that deletes site-lisp subdirectories from the default
1645 value of EMACSLOADPATH, as it is no longer needed.
1646 (check_windows_init_file): Now external, not static.
1647 Use Vload_path as is, without adding anything, as this function is now
1648 called when Vload_path is already set up.
1650 * w32.h (check_windows_init_file): Add prototype.
1652 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

1696 Remove unnecessary pointer casts.
1697 * alloc.c (record_xmalloc): New function.
1698 * lisp.h (record_xmalloc): New decl.
1699 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
1700 more like a function. This is because the pointer cast is not
1701 needed. All uses changed.
1702 * print.c (print_string, print_error_message): Avoid length recalc.
1704 Improve fix for macroexp crash with debugging (Bug#12118).
1705 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
1706 ARRAY_MARK_FLAG when checking subscripts, because ASET is
1707 not supposed to be invoked from the garbage collector.

1709 (gc_aset): New function, which is like ASET but can be
1710 used in the garbage collector.

1738 (stat_worker): New function, with most of the guts of 'stat', and
1739 with addition of handling of symlinks and support for 'lstat'.
1740 If possible, get file's attributes and security information by
1741 handle, not by name. Produce S_IFLNK bit for symlinks, when
1742 called from 'lstat'.
1743 (stat, lstat): New functions, call 'stat_worker'.
1744 (symlink, readlink, careadlinkat): Rewritten to create and resolve
1745 symlinks when the underlying filesystem supports them.
1747 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
1749 Fix macroexp crash on Windows with debugging (Bug#12118).
1750 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
1751 checking subscripts; problem introduced with the recent
1752 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
1753 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
1754 since it's used in non-static inline functions now.
1756 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
1757 Don't assume buffer size fits in 'int'. Remove unused local.

1774 * category.c (CATEGORY_INLINE):
1775 * character.c (CHARACTER_INLINE):
1776 * charset.c (CHARSET_INLINE):
1777 * composite.c (COMPOSITE_INLINE):
1778 * dispnew.c (DISPEXTERN_INLINE):
1779 * sysdep.c (SYSTIME_INLINE):
1780 Define to EXTERN_INLINE, so that the corresponding functions
1781 are compiled into code.
1782 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
1783 (INLINE_HEADER_END): New macros.
1784 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

1804 hard-coding the path separator.
1806 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
1808 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".

2281 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2283 Fast save_excursion_save and save_excursion_restore.
2284 * lisp.h (struct Lisp_Excursion): New data type.
2285 (PVEC_EXCURSION): New pseudovector type.
2286 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
2287 to deal with it. Adjust comments.

2302 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2303 emacs.c, as this is a more-suitable home. Had this been done earlier
2304 the fix for 12036 would have avoided some of the problems noted in
2305 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2306 would have been more obvious.
2307 * emacs.c: Do not include <verify.h>; no longer needed.
2308 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2309 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2310 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2311 Remove; now done in lisp.h.

2316 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2317 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2318 not be usable in #if. This simplifies things.
2320 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2322 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
2324 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

2327 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2328 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2329 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2330 Adjust to changes in lisp.h and emacs.c, by using
2331 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2332 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2333 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2334 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2335 instead of gdb_valbits.
2336 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2337 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2338 instead of gdb_array_mark_flag.
2339 (xboolvector): Get size from $->size, not $->header.size.
2340 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2341 (xreload, hook-run, hookpost-run): Remove.
2342 * emacs.c: Include <verify.h>.
2343 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2344 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2346 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2347 (gdb_USE_LSB_TAG): New enum constants.
2348 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2349 Also define these as enum constants, so they're visible to GDB.
2350 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2351 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2352 as constants, so they're visible to GDB.
2353 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
2354 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
2355 Now enum constants, not macros, so they're visible to GDB.
2356 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2357 more convenient now. All uses changed.
2358 (VALMASK) [USE_LSB_TAG]: Also define in this case.
2359 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
2361 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

2368 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
2369 add argument, tune behavior, and adjust all callers.
2371 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2373 Use typedef for EMACS_INT, EMACS_UINT.
2374 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2375 than macros. This simplifies debugging in the usual case, since
2376 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2377 and it allows expressions involving EMACS_INT casts.
2378 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2380 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

2390 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
2392 Adjust buffer text indirection counters at the end of Fkill_buffer.
2393 * buffer.c (Fkill_buffer): Adjust indirection counters when the
2394 buffer is definitely dead. This should really fix an issue reported
2395 by Christoph Scholtes again. (Bug#12007).
2396 (init_buffer_once): Initialize indirection counters of
2397 buffer_defaults and buffer_local_symbols (for sanity and safety).
2399 2012-07-24 Eli Zaretskii <eliz@gnu.org>
2401 * xdisp.c (init_iterator): Don't compute dimensions of truncation
2402 and continuation glyphs on tooltip frames, leave them at zero.
2403 Avoids continued lines in tooltips. (Bug#11832)
2405 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

2430 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2432 Swap buffer text indirection counters in Fbuffer_swap_text.
2433 * buffer.c (Fbuffer_swap_text): Swap indirections too.
2434 This avoids crash reported by Christoph Scholtes at
2435 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2437 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
2439 * nsmenu.m (Popdown_data): New struct.

2462 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
2464 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
2465 as it's limited by the amount of memory, not by INT_MAX.
2467 2012-07-21 Eli Zaretskii <eliz@gnu.org>
2469 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
2470 in special-event-map. See the discussion at

2620 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
2622 * eval.c (Fdefvar): Don't check constants since we only set the var if
2623 it's not yet defined anyway (bug#11904).
2625 * lisp.h (last_undo_boundary): Declare new var.
2626 * keyboard.c (command_loop_1): Set it.
2627 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
2628 were auto-added by the command loop (bug#11774).

3172 (font_open_by_name): Change to use length argument.
3173 Adjust users accordingly.
3174 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
3176 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
3177 Change to return ptrdiff_t.
3178 (xfont_list_pattern, xfont_match): Use length returned by
3179 xfont_decode_coding_xlfd.

3193 * s/aix4-2.h (unix): Remove; no longer needed.
3195 EMACS_TIME simplification (Bug#11875).
3196 This replaces macros (which typically do not work in GDB)
3197 with functions, typedefs and enums, making the code easier to debug.
3198 The functional style also makes code easier to read and maintain.
3199 * systime.h: Include <sys/time.h> on all hosts, not just if
3200 WINDOWSNT, since 'struct timeval' is needed in general.
3201 (EMACS_TIME): Now a typedef, not a macro.
3202 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
3204 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
3205 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
3206 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
3207 (EMACS_TIME_LE): Now functions, not macros.
3208 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
3209 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
3210 which are not functions. All uses rewritten to use:
3211 (make_emacs_time): New function.
3212 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
3213 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3214 not functions. All uses rewritten to use the following, respectively:
3215 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3216 (add_emacs_time, sub_emacs_time): New functions.
3217 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
3218 * fileio.c (Fcopy_file):
3219 * xterm.c (XTflash): Get the current time closer to when it's used.
3220 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

3226 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
3227 * frame.c (Fmake_terminal_frame):
3228 * gtkutil.c (get_utf8_string):
3230 * nsmenu.m (ns_update_menubar):
3231 * regex.c (regerror):
3232 Prefer memcpy to strncpy and strncat when either will do.
3233 * fileio.c (Fsubstitute_in_file_name):
3234 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
3235 (menu_separator_name_p):
3236 * nsmenu.m (ns_update_menubar):
3237 Prefer memcmp to strncmp when either will do.
3238 * nsterm.m: Include <ftoastr.h>.
3240 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3241 Prefer snprintf to strncpy.
3242 * nsterm.m (ns_term_init):
3243 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3244 * nsterm.m (ns_term_init):
3245 Avoid the need for strncpy, by using build_string or
3246 make_unibyte_string directly. Use dtoastr, not snprintf.
3247 * process.c (Fmake_network_process): Diagnose service names that
3248 are too long, rather than silently truncating them or creating
3249 non-null-terminated names.
3250 (Fnetwork_interface_info): Likewise, for interface names.
3251 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3252 Prefer sprintf to strncat.
3253 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
3254 Prefer vsnprintf to vsprintf + strncpy.
3256 2012-07-10 Glenn Morris <rgm@gnu.org>
3258 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
3259 Clarify fallback case.
3261 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3263 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
3264 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
3265 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3266 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3267 where argument type is known to be a Lisp_Cons.
3269 2012-07-10 Tom Tromey <tromey@redhat.com>
3271 * bytecode.c (BYTE_CODE_THREADED): New macro.
3272 (BYTE_CODES): New macro. Replaces all old byte-code defines.
3273 (enum byte_code_op): New type.

3277 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3279 Optimize pure C strings initialization.
3280 * lisp.h (make_pure_string): Fix prototype.
3281 (build_pure_c_string): New function, defined as static inline. This
3282 provides a better opportunity to optimize away calls to strlen when
3283 the function is called with compile-time constant argument.
3284 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
3285 argument, adjust users accordingly. Use build_pure_c_string where
3287 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
3288 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
3289 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
3291 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3293 Avoid calls to strlen in miscellaneous functions.
3294 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
3295 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
3296 * lread.c (openp): Likewise.
3298 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3300 Avoid calls to strlen in path processing functions.
3301 * fileio.c (file_name_as_directory): Add comment. Change to add
3302 srclen argument and return the length of result. Adjust users
3304 (directory_file_name): Fix comment. Change to add srclen argument,
3305 swap 1st and 2nd arguments to obey the common convention.
3306 Adjust users accordingly.
3307 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
3309 2012-07-10 Glenn Morris <rgm@gnu.org>
3311 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
3312 Move PENDING_OUTPUT_COUNT definition to configure.
3314 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
3315 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
3316 * s/gnu.h (DATA_START): Move definitions to configure.
3318 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
3319 We include usg5-4-common.h, which defines them both.
3321 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
3322 O_RDONLY already includes it).
3324 Stop ns builds setting the EMACSLOADPATH environment variable.
3325 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3326 Now it does not set EMACSLOADPATH, just returns the load-path string.
3327 * nsterm.h: Update accordingly.
3328 * lread.c [HAVE_NS]: Include nsterm.h.
3329 (init_lread) [HAVE_NS]: Use ns_load_path.
3330 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
3332 2012-07-09 Glenn Morris <rgm@gnu.org>
3334 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
3335 since the included bsd-common.h does so.
3337 Stop ns builds setting the EMACSPATH environment variable.
3338 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
3339 (ns_init_paths): Do not set EMACSPATH.
3340 * nsterm.h (ns_exec_path): Add it.
3341 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
3344 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
3346 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
3348 * process.c (wait_reading_process_output): 'waitchannels' was unset
3349 when read_kbd || !NILP (wait_for_cell); fix this.
3351 Add GCC-style 'const' attribute to functions that can use it.
3352 * character.h (char_resolve_modifier_mask):
3353 * keyboard.h (make_ctrl_char):
3354 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
3355 (init_character_once, next_almost_prime, init_fns, init_image)
3356 (flush_pending_output, init_sound):
3357 * mem-limits.h (start_of_data):
3358 * menu.h (finish_menu_items):
3359 Add ATTRIBUTE_CONST.

3361 Declare the dummy function with ATTRIBUTE_CONST.
3362 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
3363 Add decls with ATTRIBUTE_CONST.
3365 Minor improvements to make_formatted_string.
3366 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
3367 where int is good enough, as vsprintf returns an int.
3368 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
3370 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3372 Use make_formatted_string to avoid double length calculation.
3373 * lisp.h (make_formatted_string): New prototype.
3374 * alloc.c (make_formatted_string): New function.
3375 * buffer.c (Fgenerate_new_buffer_name): Use it.
3376 * dbus.c (syms_of_dbusbind): Likewise.

3378 * filelock.c (get_boot_time): Likewise.
3379 * frame.c (make_terminal_frame, set_term_frame_name)
3380 (x_report_frame_params): Likewise.
3381 * image.c (gs_load): Likewise.
3382 * minibuf.c (get_minibuffer): Likewise.
3383 * msdos.c (dos_set_window_size): Likewise.
3384 * process.c (make_process): Likewise.

3397 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3399 Move marker debugging code under MARKER_DEBUG.
3400 * marker.c (MARKER_DEBUG): Move marker debugging code under
3401 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
3402 for bootstrap with --enable-checking (~3x slowdown reported
3403 by Juanma Barranquero <lekktu@gmail.com>).
3404 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
3406 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
3408 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
3409 See <http://bugs.gnu.org/11825#29>.
3411 2012-07-08 Eli Zaretskii <eliz@gnu.org>
3413 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
3414 has no font, use the frame's font. (Bug#11813)
3415 (display_line): Add commentary about displaying truncation glyphs
3417 (produce_special_glyphs): Move here from term.c.
3419 * term.c (produce_special_glyphs): Move to xdisp.c.
3421 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
3424 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
3426 * xdisp.c (display_line): Avoid warning about implicit declaration
3429 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
3431 * lisp.h: Remove empty conditional.
3433 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3435 * lread.c (load_path_check): Now static.
3437 Fix some minor --with-ns problems found by static checking.
3438 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
3439 (x_set_font) [!HAVE_X_WINDOWS]:
3440 * image.c (xpm_load_image) [HAVE_NS]:
3441 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
3442 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
3443 Remove unused local.
3444 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
3445 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
3446 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
3447 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
3448 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
3449 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
3450 Fix pointer signedness problem.
3451 * xfaces.c (FRAME_X_FONT_TABLE):
3452 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
3454 2012-07-07 Glenn Morris <rgm@gnu.org>
3456 * lread.c (load_path_check): New function, split from init_lread.
3457 (init_lread): Reorganize. Motivation:
3458 If EMACSLOADPATH is set, check/warn about that rather than the
3459 defaults, which we are not going to use. Hence we can remove
3460 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
3461 Don't warn if site-lisp directories are missing.
3462 If not installed, start from a blank load-path, since
3463 PATH_LOADSEARCH refers to the eventual installation directories.
3465 2012-07-07 Eli Zaretskii <eliz@gnu.org>
3467 Support truncation and continuation glyphs on GUI frames, when
3468 fringes are disabled. (Bug#11832)
3469 * xdisp.c (init_iterator): Get dimensions of truncation and
3470 continuation glyphs even if on GUI frames.
3471 Adjust it->last_visible_x on GUI frames when the left or right fringes,
3472 or both, are absent.
3473 (start_display, move_it_in_display_line_to): Handle the case of a
3474 GUI frame without a fringe to display continuation or truncation
3476 (insert_left_trunc_glyphs): Support GUI frames: make sure
3477 truncation glyphs overwrite enough glyphs from the current line to
3478 have sufficient space in pixels.
3479 (display_line): Support truncation and continuation glyphs on GUI
3480 frames. If some spare pixels are left on the line after inserting
3481 the truncation glyphs, fill that space with a stretch glyph of a
3482 suitably computed width.
3484 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3485 produce_glyphs, to support GUI sessions.
3487 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3489 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3491 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3493 Do not require float-time's arg to fit in time_t (Bug#11825).
3494 This works better on hosts where time_t is unsigned, and where
3495 float-time is applied to the (negative) difference between two times.
3496 * editfns.c (decode_time_components): Last arg is now double *,
3497 not int *, and means to store all the result as a double, without
3498 worrying about whether the seconds part fits in time_t.
3499 All callers changed.
3500 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3501 All callers changed.
3502 (Ffloat_time): Do not fail merely because the specified time falls
3503 outside of time_t range.
3505 2012-07-07 Glenn Morris <rgm@gnu.org>
3507 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

3511 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3513 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3514 Update dependencies.
3516 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3518 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3520 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3521 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3522 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3523 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3524 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3525 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3527 * xfont.c (compare_font_names): Redo to omit the need for casts.
3529 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3531 * xfns.c (Fx_change_window_property): Doc fix.
3532 * w32fns.c (Fx_change_window_property): Doc fix.
3534 * w32fns.c (Fx_window_property): Accept the same arguments as the
3535 X Windows version. Doc fix.
3536 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3538 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3539 Eli Zaretskii <eliz@gnu.org>
3541 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3542 Windows-specific code from nt/config.nt moved here.
3543 Obsolete settings removed.
3545 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3547 * process.c: Avoid unnecessary calls to gettime.
3548 (wait_reading_process_output): Don't get the time of day
3549 when gobbling data immediately and not waiting, as there's no need
3550 for it in that case. This removes a FIXME.
3552 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3554 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3555 is defined (Bug#11768).
3557 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3559 Fix marker debugging code.

3561 if buffer is not multibyte.
3562 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3563 Call byte_char_debug_check with correct arguments.
3565 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3567 Compile marker debugging code only if ENABLE_CHECKING is defined.
3568 * marker.c (byte_char_debug_check, count_markers):
3569 Use only if ENABLE_CHECKING is defined.
3570 (byte_debug_flag): Remove.
3571 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3572 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
3574 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3576 Avoid code repetition in marker-related functions.
3577 * marker.c (attach_marker): New function.
3578 (Fset_marker, set_marker_restricted, set_marker_both)
3579 (set_marker_restricted_both): Use it.

3600 (save_restriction_save): Use build_marker.
3601 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
3602 * window.c (save_window_save): Likewise.
3604 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3606 Do not use Fdelete_overlay in delete_all_overlays
3607 to avoid redundant calls to unchain_overlay.
3608 * buffer.c (drop_overlay): New function.
3609 (delete_all_overlays, Fdelete_overlay): Use it.
3610 * minibuf.c (get_minibuffer): Fix comment.
3612 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3614 Port to OpenBSD 5.1 amd64.
3615 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
3616 This is needed for OpenBSD, and should be harmless on all BSD systems.
3617 Also, include <sys/sysctl.h>, as it should be available on all
3618 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
3619 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
3620 use p_pid member, not kp_proc.pid.
3622 2012-07-06 Glenn Morris <rgm@gnu.org>
3624 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
3626 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
3628 More xmalloc and related cleanup.
3629 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

3636 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
3637 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
3639 Omit needless casts involving void * pointers and allocation.
3640 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
3641 as the former is more robust if P's type is changed.
3642 Prefer xzalloc to xmalloc + memset 0.
3643 Simplify malloc-or-realloc to realloc.
3644 Don't worry about xmalloc returning a null pointer.
3645 Prefer xstrdup to xmalloc + strcpy.
3646 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
3648 * keyboard.c (apply_modifiers_uncached): Prefer local array to
3649 alloca of a constant.
3651 2012-07-05 Eli Zaretskii <eliz@gnu.org>
3653 * xdisp.c (display_line): Fix horizontal pixel coordinates when
3654 hscroll is larger than the line width. Fixes long and futile
3655 looping inside extend_face_to_end_of_line (on a TTY) producing
3656 glyphs that are not needed and thrown away.
3658 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3660 * marker.c (set_marker_restricted_both): Simplify by using
3663 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
3665 * editfns.c (region_limit): Simplify by using clip_to_bounds.
3667 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
3669 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
3670 not defined (Bug#11768).
3671 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
3672 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
3673 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
3674 followed by gtk_box_set_homogeneous (Bug#11768).
3675 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
3676 (update_theme_scrollbar_width, xg_create_scroll_bar):
3677 Use gtk_scrollbar_new (Bug#11768).
3678 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
3679 (is_box_type): New function (Bug#11768).
3680 (xg_tool_item_stale_p): Call is_box_type.
3681 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
3682 with default display (Bug#11768).
3684 2012-07-05 Eli Zaretskii <eliz@gnu.org>
3686 * xdisp.c (window_hscroll_limited): New function.
3687 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
3688 coordinates when window's hscroll is set to insanely large
3691 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
3693 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
3694 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
3696 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3699 * lisp.h (xzalloc): New prototype. Omit needless casts.

3754 * fileio.c (time_error_value): Check the right error number.
3755 Problem reported by Troels Nielsen in
3756 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
3758 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3760 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
3761 This should be fixed in a better way; see Eli Zaretskii in
3762 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
3763 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
3765 * fileio.c (time_error_value): Rename from special_mtime.
3766 The old name's problems were noted by Eli Zaretskii in
3767 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
3769 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
3770 This variable's comment says Emacs needs at least one GDB-visible
3771 symbol of type enum pvec_type, to work around GDB problems.
3772 The symbol's value doesn't matter.
3774 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
3775 that causes compilation to fail on pre-C99 compilers.
3777 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
3779 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
3780 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
3782 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3784 * buffer.c (init_buffer_once): Fix initialization of
3785 headers for buffer_defaults and buffer_local_symbols.
3786 Reported by Juanma Barranquero <lekktu@gmail.com>.
3788 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
3790 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
3791 * lisp.h (enum pvec_type): Use fewer bits.
3792 (PSEUDOVECTOR_SIZE_BITS): New constant.
3793 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
3794 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
3795 change in pvec_type.
3796 (PSEUDOVECTOR_TYPEP): New macro.
3797 (TYPED_PSEUDOVECTORP): Use it.
3798 * fns.c (internal_equal): Adapt code to extract pvectype.

3800 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
3801 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
3802 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
3803 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
3804 (sweep_vectors): Use it. Use local var `total_bytes' instead of
3805 abusing vector->header.next.nbytes.
3806 (live_vector_p): Use PVEC_TYPE.
3807 (mark_object): Adapt code to extract pvectype. Use switch.
3809 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3811 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
3812 Tighten new eassert a bit.
3814 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3816 Fix compilation with --enable-gcc-warnings and -O1
3818 * doprnt.c (doprnt): Change type of tem to int, initialize
3819 to avoid compiler warning. Add eassert.
3820 * search.c (simple_search): Initialize match_byte to avoid
3821 compiler warning. Add eassert.
3823 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3825 Avoid weird behavior with large horizontal scrolls.
3826 Without this change, for example, large hscroll values would
3827 mess up Emacs's display on Fedora 15 x86, presumably due to
3828 overflows in int calculations in the display code.
3829 Also, if buffers had long lines, Emacs would freeze.
3830 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
3831 (set_window_hscroll): New function, containing the old guts of
3832 Fset_window_hscroll. Return the clipped value.
3833 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
3834 This avoids the need to check against PTRDIFF_MAX.
3836 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
3838 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3840 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
3842 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3844 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
3845 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
3846 since GCC 4.4.6 issues a bogus warning for them.
3848 Fix bugs in file timestamp newness comparisons.
3849 * fileio.c (Ffile_newer_than_file_p):
3850 * lread.c (Fload): Use full timestamp resolution of files,
3851 not just the 1-second resolution, so that files that are only
3852 slightly newer still count as newer.
3853 * fileio.c (Ffile_newer_than_file_p): Don't assume file
3854 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
3856 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
3858 * fileio.c: Improve handling of file time marker. (Bug#11852)
3859 (special_mtime): New function.
3860 (Finsert_file_contents, Fverify_visited_file_modtime):
3861 Use it to set special mtime values consistently.
3863 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
3865 * fileio.c (Finsert_file_contents): Properly handle st_mtime
3866 marker for non-existing file. (Bug#11852)
3868 2012-07-03 Glenn Morris <rgm@gnu.org>
3870 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
3871 and did not make it into globals.h).
3873 2012-07-03 Tom Tromey <tromey@redhat.com>
3875 * window.c (Fset_window_margins, Fset_window_fringes)
3876 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
3877 * textprop.c (Fprevious_property_change): No longer static.
3878 * syntax.c (Fsyntax_table_p): No longer static.

3900 * intervals.h: Remove EXFUNs.
3901 * fontset.h: Remove EXFUN.

3906 * w32term.h: Remove EXFUNs.
3907 * window.h: Remove EXFUNs.
3908 * xsettings.h: Remove EXFUN.
3909 * xterm.h: Remove EXFUN.
3911 2012-07-03 Glenn Morris <rgm@gnu.org>
3913 * lisp.h (Frandom): Make it visible to C.
3914 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
3915 buffer for invisible buffers. (Bug#1229)
3917 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3919 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
3920 values which aren't power of 2.
3921 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
3922 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
3925 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
3927 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
3929 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3931 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3933 * alloc.c (allocate_vector_block): Remove redundant
3934 calls to mallopt if DOUG_LEA_MALLOC is defined.
3935 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3936 avoid calls to mallopt if zero_vector is returned.
3938 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3940 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
3941 is enabled, avoid dereferencing NULL current_sblock if
3944 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3946 Cleanup basic buffer management.
3947 * buffer.h (struct buffer): Change layout to use generic vector
3948 marking code. Fix some comments. Change type of 'clip_changed'
3949 to bitfield. Remove unused #ifndef old.
3950 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3951 (GET_OVERLAYS_AT): Fix indentation.
3952 (for_each_per_buffer_object_at): New macro.
3953 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
3954 (Fbuffer_local_variables): Use it.
3955 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
3956 * alloc.c (allocate_buffer): Adjust to match new layout of
3957 struct buffer. Fix comment.
3958 (mark_overlay): New function.
3959 (mark_buffer): Use it. Use mark_vectorlike to mark normal
3960 Lisp area of struct buffer.
3961 (mark_object): Use it. Adjust marking of misc objects
3962 and related comments.
3964 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3966 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3967 wrapper that is not needed because the wrapped code is a no-op (zero
3968 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3969 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3971 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3973 * alloc.c (mark_buffer): Simplify. Remove prototype.
3974 (mark_object): Add comment. Reorganize marking of vector-like
3975 objects. Use CHECK_LIVE for all vector-like objects except buffers
3976 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3977 Avoid redundant calls to mark_vectorlike for bool vectors.
3979 2012-06-30 Glenn Morris <rgm@gnu.org>
3981 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3983 * epaths.in (PATH_SITELOADSEARCH): New.
3984 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3985 This is rather than relying on --enable-locallisppath elements
3986 having "site-lisp" in their names. (Bug#10208#25, 11658)
3988 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3990 * w32proc.c (sys_select): Accept and ignore one more argument.
3992 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3994 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3995 (pselect) [!MS_DOS]: Redirect to sys_select.
3997 * sysdep.c: Don't include dos.h and dosfns.h.
3999 * process.c (sys_select):
4000 * msdos.c (sys_select): Accept one more argument and ignore it.
4002 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4003 adapt data types and code to that.
4006 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4007 which clashes with the gnulib function of the same name.
4009 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4011 * font.c (font_style_to_value, font_style_symbolic)
4012 (font_prop_validate_style): Add type checks for values in
4015 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4017 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4020 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4022 * xdisp.c (try_window_id): Undo last change.
4024 * w32.c (getwd): Adjust commentary about startup_dir.
4025 (init_environment): Always call sys_access, even in non-MSVC
4026 builds. Don't chdir to the directory of the Emacs executable.
4027 This undoes code from 1997 which was justified by the need to
4028 "avoid conflicts when removing and renaming directories". But its
4029 downside was that every relative file name was being interpreted
4030 relative to the directory of the Emacs executable, which can never
4031 be TRT. In particular, it broke sys_access when called with
4032 relative file names.
4033 (sys_access): Map GetLastError to errno.
4035 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4037 * window.h (struct window): Change type of 'fringes_outside_margins'
4038 to bitfield. Fix comment. Adjust users accordingly.
4039 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4041 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4044 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4046 * gnutls.c (emacs_gnutls_handshake):
4047 Add QUIT to make the loop interruptible.
4049 2012-06-29 Glenn Morris <rgm@gnu.org>
4051 * charset.c (init_charset): Make lack of etc/charsets fatal.
4053 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4055 * editfns.c (region_limit): Fix type mismatch.
4057 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4059 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4060 undefined. Convert from xassert to eassert.
4061 * nsmenu.m: Convert from xassert to eassert.
4062 * nsterm.m: Likewise.
4064 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4066 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4068 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4070 Avoid integer overflow on scroll-left and scroll-right.
4071 * window.c (HSCROLL_MAX): New macro.
4072 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

4227 Use sprintf return value instead of invoking strlen on result.
4228 In the old days this wasn't portable, since some sprintf
4229 implementations returned char *. But they died out years ago and
4230 Emacs already assumes sprintf returns int.
4231 Similarly for float_to_string.
4232 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

4240 Use sprintf or float_to_string result to avoid need to call strlen.
4241 * data.c (Fnumber_to_string):
4242 Use make_unibyte_string, since the string must be ASCII.
4243 * lisp.h, print.c (float_to_string): Now returns int length.
4244 * term.c (produce_glyphless_glyph):
4245 Use sprintf result rather than recomputing it.
4247 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
4248 * Makefile.in (ALL_CFLAGS):
4249 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

4276 * xfns.c (x_window): Remove redundant cast.
4278 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
4280 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
4281 `const char *' to `char *' to avoid compiler warning.
4283 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4285 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4286 instead of truncating it to 63 (admittedly a generous limit).

4345 * dispnew.c (Fsleep_for, sit_for):
4346 * keyboard.c (kbd_buffer_get_event):
4347 * process.c (Faccept_process_output):
4348 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
4349 This improves on the previous patch, which introduced a bug
4350 when time_t is unsigned and as wide as intmax_t.
4351 See <http://bugs.gnu.org/9000#51>.
4353 2012-06-23 Eli Zaretskii <eliz@gnu.org>

4370 Privately reported by Herbert J. Skuhra.
4371 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

4374 not make_lisp_timeval, when the argument is of type EMACS_TIME.
4376 2012-06-23 Eli Zaretskii <eliz@gnu.org>
4378 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
4379 last argument of make_unibyte_string.
4381 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
4382 language ID in the event parameters.
4384 * w32term.c (w32_read_socket): Put the new keyboard codepage into
4385 event.code, not the obscure "character set ID".

4416 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
4418 Support higher-resolution time stamps (Bug#9000).
4419 The time stamps are only nanosecond-resolution at the C level,
4420 since that's the best that any real-world system supports now.
4421 But they are picosecond-resolution at the Lisp level, as that's
4422 easy, and leaves room for future OS improvements.
4424 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
4427 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
4428 Don't get current time unless it's needed.
4430 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
4431 now provides it if it's absent.
4432 (start_atimer): Port to higher-res time stamps.
4433 Check for time stamp overflow. Don't get current time more
4434 often than is needed.
4436 * buffer.h (struct buffer): Buffer modtime now has high resolution.
4437 Include systime.h, not time.h.
4438 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
4440 * dired.c: Include stat-time.h.
4441 (Ffile-attributes): File times now have higher resolution.

4444 (struct image): Timestamp now has higher resolution.
4446 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
4447 has at least microseconds now. All uses removed.
4448 (update_frame, update_single_window, update_window, update_frame_1)
4449 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
4450 (duration_to_sec_usec): Remove; no longer needed.
4452 * editfns.c (time_overflow): Now extern.
4453 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
4454 (float-time, Fformat_time_string, Fcurrent_time_string)

4458 (decode_time_components, lisp_seconds_argument): New functions.
4459 (make_time): Now static.
4460 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
4461 Report an error if the time is invalid, rather than having the caller
4464 * fileio.c: Include <stat-time.h>
4465 (Fcopy_file): Copy higher-resolution time stamps.
4466 Prefer to set the time stamp via a file descriptor if that works.
4467 (Fset_file_times, Finsert_file_contents, Fwrite_region)
4468 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
4469 (Fvisited_file_modtime, Fset_visited_file_modtime):
4470 Support higher-resolution time stamps.
4472 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
4474 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
4476 * image.c (prepare_image_for_display, clear_image_cache)
4477 (lookup_image): Port to higer-resolution time stamps.
4479 * keyboard.c (start_polling, bind_polling_period):
4480 Check for time stamp overflow.
4481 (read_char, kbd_buffer_get_event, timer_start_idle)
4482 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4483 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4484 Port to higher-resolution time stamps. Do not assume time_t is signed.
4485 (decode_timer): New function. Timers are now vectors of length 9,
4486 not 8, to accommodate the picosecond component.
4487 (timer_check_2): Use it.
4489 * nsterm.m (select_timeout, timeval_subtract): Remove.
4490 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4491 as they're a bit more accurate and handle overflow better.
4492 (ns_select): Change prototype to be compatible with pselect.
4493 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4494 * nsterm.h (ns_select): Adjust prototype.
4496 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4497 us-resolution time stamps.
4498 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4500 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4502 * lisp.h (time_overflow): New decl.
4503 (wait_reading_process_output): First arg is now intmax_t, not int,
4504 to accommodate larger waits.
4506 * process.h (struct Lisp_Process.read_output_delay):
4507 Now counts nanoseconds, not microseconds.
4508 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4510 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4511 (wait_reading_process_output):
4512 Port to ns-resolution time stamps.
4513 (Faccept_process_output, wait_reading_process_output):
4514 Check for time stamp overflow. Do not assume time_t is signed.
4515 (select_wrapper): Remove; we now use pselect.
4516 (Fprocess_attributes): Now generates ns-resolution time stamps.
4518 * sysdep.c: Include utimens.h. Don't include utime.h
4519 or worry about struct utimbuf; gnulib does that for us now.
4520 (gettimeofday): Remove; gnulib provides a substitute.
4521 (make_timeval): New function.
4522 (set_file_times): Now sets ns-resolution time stamps.
4523 New arg FD; all uses changed.
4524 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4525 (system_process_attributes):
4526 Now returns ns-resolution time stamp. All uses changed.
4527 Check for time stamp overflow.
4529 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4530 provides a substitute now.
4532 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4533 since it guarantees struct timespec.
4534 (EMACS_TIME): Now struct timespec, so that we can support
4535 ns-resolution time stamps.
4536 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4537 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4538 (EMACS_USECS): Remove.
4539 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4540 so multiply the arg by 1000 before storing it.
4541 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4543 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4544 Port to ns-resolution time stamps.
4545 (EMACS_TIME_NEG_P): Remove; replaced by....
4546 (EMACS_TIME_SIGN): New macro.
4547 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4548 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
4549 (set_file_times, make_time, lisp_time_argument): Adjust signature.
4550 (make_timeval, make_lisp_time, decode_time_components): New decls.
4551 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4552 that it mishandled time_t overflow. You can't compare by subtracting!
4553 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4554 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4556 * term.c: Include <sys/time.h>.

4593 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
4594 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

4645 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
4646 gets killed during executing of this function (Bug#11665).
4647 Try to always return Qt when the buffer has been actually killed.
4648 (Vkill_buffer_query_functions): In doc-string say that functions
4649 run by this hook should not change the current buffer.
4651 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
4653 Fix recently-introduced process.c problems found by static checking.

4679 * coding.c (produce_chars): Use ptrdiff_t, not int.
4681 * xterm.c (x_draw_underwave): Check for integer overflow.
4682 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

4869 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
4870 Use an inline function on all platforms when using the union type,
4871 since this is simpler and 'static inline' can be used portably

4982 * alloc.c (allocate_vectorlike): Fix last change.

4986 Block-based vector allocation of small vectors.

4988 adjust comment accordingly.
4989 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

5015 * doprnt.c (doprnt): Truncate multibyte char correctly.
5016 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5017 would mishandle a string argument "Xc" if X was a multibyte
5018 character of length 2: it would truncate after X's first byte
5019 rather than including all of X.
5021 2012-06-06 Chong Yidong <cyd@gnu.org>
5023 * buffer.c (word_wrap): Doc fix.

5048 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5049 (note_mode_line_or_margin_highlight): If there is no help echo,
5050 use mode-line-default-help-echo. Handle the case where the mouse
5051 position is past the end of the mode line string.
5053 * buffer.c (buffer_local_value_1): New function, split from
5054 Fbuffer_local_value; can return Qunbound.

5068 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5070 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5072 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5073 Convert pctcpu and pctmem to Lisp float properly.
5074 Let the compiler fold better, as 100.0/0x8000 is exact.
5076 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5078 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5081 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5083 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5085 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5087 For a 'struct window', replace some Lisp_Object fields to
5088 bitfields where appropriate, remove unused fields.
5089 * window.h (struct window): Remove unused 'last_mark_x' and
5090 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5091 change it's type from Lisp_Object to bitfield.
5092 Change type of 'force_start', 'optional_new_start',
5093 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5094 fields from Lisp_Object to bitfield. Adjust users accordingly.
5096 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5098 Pacify gcc -Wdouble-precision when using Xaw.
5099 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5100 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5101 Use 'float' consistently, rather than 'float' in most places
5102 and 'double' in a couple of places.
5104 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5106 * xdisp.c (handle_stop): Detect whether we have overlay strings
5107 loaded by testing it->current.overlay_string_index to be
5108 non-negative, instead of checking whether n_overlay_strings is
5109 positive. (Bug#11587)
5111 2012-05-31 Chong Yidong <cyd@gnu.org>
5113 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5115 * doc.c (Fsubstitute_command_keys): Doc fix.
5117 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5119 * search.c (search_buffer): Remove calls to
5120 r_alloc_inhibit_buffer_relocation, as it is now called by
5121 maybe_unify_char, which was the cause of relocation of buffer text
5124 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5126 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5127 for the duration of call to load_charset, to avoid problems with
5128 callers of maybe_unify_char that access buffer text through C
5131 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5132 decrement the inhibition flag, instead of just setting or
5135 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5137 Remove obsolete '#define static' cruft.
5138 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5139 This #undef was "temporary" in 2000; it is no longer needed
5140 now that '#define static' has gone away.
5141 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5142 (gray_bitmap_bits): Remove; no longer needed.
5143 All uses replaced with definiens.
5144 * xterm.c: Include "bitmaps/gray.xbm".
5146 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5148 Clean up __executable_start, monstartup when --enable-profiling.
5149 The following changes affect the code only when profiling.
5150 * dispnew.c (__executable_start): Rename from safe_bcopy.
5151 Define only on platforms that need it.
5152 * emacs.c: Include <sys/gmon.h> when profiling.
5153 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5154 (__executable_start): Remove decl, since lisp.h does it now.
5155 (safe_bcopy): Remove decl; no longer has that name.
5156 (main): Coalesce #if into single bit of code, for simplicity.
5157 Cast pointers to uintptr_t, since standard libraries want integers
5159 * lisp.h (__executable_start): New decl.
5161 2012-05-31 Glenn Morris <rgm@gnu.org>
5163 * image.c (Fimagemagick_types): Doc fix.

5182 * lread.c (read1): Tiny simplification.
5184 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5186 Do not create empty overlays with the evaporate property (Bug#9642).
5187 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5188 Bug#9642, but explicitly check that the buffer the overlay would
5189 be moved to is live and rearrange lines to make sure that errors
5190 will not put the overlay in an inconsistent state.
5191 (Fdelete_overlay): Cosmetics.
5193 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5195 * w32term.c (my_bring_window_to_top): New function.
5196 (x_raise_frame): Use handle returned by DeferWindowPos, which
5197 could be different from the original one.

5201 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5202 by calling BringWindowToTop.
5204 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
5205 (WM_EMACS_END): Increase by one.
5207 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5209 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5210 This avoids undefined behavior that might cause the eassert
5211 to not catch an out-of-range value.
5213 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5215 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
5216 Update dependencies.
5218 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5220 * bidi.c (bidi_mirror_char): Fix last change.
5222 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
5224 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
5225 when referring to sectname field in printf format.
5227 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5229 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5230 Only r_alloc_inhibit_buffer_relocation needed to be added;
5231 the others were already declared.
5233 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5234 before checking whether it's out of range. Put the check inside
5236 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5238 2012-05-27 Ken Brown <kbrown@cornell.edu>
5240 * callproc.c (Fcall_process): Restore a line that was accidentally
5241 commented out in the 2011-02-13 change (bug#11547).
5243 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5245 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5246 defined on ralloc.c.
5248 * buffer.c [REL_ALLOC]: Remove prototypes of
5249 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5250 they are now on lisp.h.
5252 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5254 * search.c (search_buffer): Use it to inhibit relocation of buffer
5255 text while re_search_2 is doing its job, because re_search_2 is
5256 passed C pointers to buffer text. (Bug#11519)
5258 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5261 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5262 state after an additional call to move_it_in_display_line_to, keep
5263 the values of it->max_ascent and it->max_descent found for the
5265 (pos_visible_p): Revert the comparison against bottom_y to what it
5266 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5269 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5271 Fix coding-related core dumps with gcc -ftrapv.
5272 The code was computing A - B, where A and B are pointers, and B is
5273 random garbage. This can lead to core dumps on platforms that
5274 have special pointer registers, and it also leads to core dumps on
5275 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5276 A - B only when B is initialized properly.
5277 * coding.c (coding_set_source, coding_set_destination): Return void.
5278 (coding_change_source, coding_change_destinations): New functions,
5279 with the old behaviors of coding_set_source and coding_set_destination.
5280 All callers that need an offset changed to use these new functions.
5282 2012-05-26 Glenn Morris <rgm@gnu.org>
5284 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5286 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5288 Extend mouse support on W32 text-mode console.
5289 * xdisp.c (draw_row_with_mouse_face):
5290 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5292 * w32console.c: Include window.h.
5293 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5295 (initialize_w32_display): Initialize mouse-highlight data.
5297 * w32inevt.c: Include termchar.h and window.h.
5298 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5299 moves, call note_mouse_highlight. If help_echo changed, call
5300 gen_help_event to produce help-echo message in the echo area.
5301 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5304 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5306 * lread.c (read1): Simplify slightly to avoid an overflow warning
5307 with GCC 4.7.0 on x86-64.
5309 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5311 * bidi.c (bidi_mirror_char): Revert last change: an int is
5312 definitely wide enough here.
5314 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5316 Fix integer width and related bugs (Bug#9874).
5317 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
5318 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
5319 (string_bytes, check_sblock, allocate_string_data):
5320 (compact_small_strings, Fmake_bool_vector, make_string)
5321 (make_unibyte_string, make_multibyte_string)
5322 (make_string_from_bytes, make_specified_string)
5323 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
5324 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
5326 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5327 (allocate_pseudovector):
5328 Use int, not EMACS_INT, where int is wide enough.
5329 (inhibit_garbage_collection, Fgarbage_collect):
5330 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5331 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
5332 int might not be wide enough.
5333 (bidi_cache_search, bidi_cache_find, bidi_init_it)
5334 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5335 (bidi_at_paragraph_end, bidi_find_paragraph_start)
5336 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5337 (bidi_level_of_next_char, bidi_move_to_visually_next):
5338 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5339 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5340 (Fkill_buffer, Fset_buffer_major_mode)
5341 (advance_to_char_boundary, Fbuffer_swap_text)
5342 (Fset_buffer_multibyte, overlays_at, overlays_in)
5343 (overlay_touches_p, struct sortvec, record_overlay_string)
5344 (overlay_strings, recenter_overlay_lists)
5345 (adjust_overlays_for_insert, adjust_overlays_for_delete)
5346 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5347 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5348 (Foverlay_recenter, last_overlay_modification_hooks_used)
5349 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5350 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5351 (validate_region): Omit unnecessary test for b <= e,
5352 since that's guaranteed by the previous test.
5353 (adjust_overlays_for_delete): Avoid pos + length overflow.
5354 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5355 (report_overlay_modification):
5356 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5357 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5358 Omit pointer cast, which isn't needed anyway, and doesn't work
5359 after the EMACS_INT -> ptrdiff_t change.
5360 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
5361 * buffer.h: Adjust decls to match defn changes elsewhere.
5362 (struct buffer_text, struct buffer):
5363 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5364 Use EMACS_INT, not int, where int might not be wide enough.
5365 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
5366 not int, to avoid needless 32-bit limit on 64-bit hosts.
5367 (exec_byte_code): Use tighter memory-full test, one that checks
5368 for alloca overflow. Don't compute the address of the object just
5369 before an array, as that's not portable. Use EMACS_INT, not
5370 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5371 * callint.c (Fcall_interactively):
5372 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5373 * callproc.c (call_process_kill, Fcall_process):
5374 Don't assume pid_t fits into an Emacs fixnum.
5375 (call_process_cleanup, Fcall_process, child_setup):

5377 (call_process_cleanup, Fcall_process, delete_temp_file)
5378 (Fcall_process_region):
5379 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5380 (Fcall_process): Simplify handling of volatile integers.
5381 Use int, not EMACS_INT, where int will do.
5382 * casefiddle.c (casify_object, casify_region, operate_on_word)
5383 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5384 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5385 (casify_object): Avoid integer overflow when overallocating buffer.
5386 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5387 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
5388 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
5389 * category.h (CATEGORYP): Don't assume arg is nonnegative.
5390 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
5391 integers are now checked earlier. All uses replaced with XINT.
5393 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5394 For CCL_MapSingle, check that content and value are in int range.
5395 (ccl_driver, Fregister_code_conversion_map):
5396 Check that Vcode_version_map_vector is a vector.
5397 (resolve_symbol_ccl_program): Check that vector header is in range.
5398 Always copy the vector, so that we can check its contents reliably
5399 now rather than having to recheck each instruction as it's being
5400 executed. Check that vector words fit in 'int'.
5401 (ccl_get_compiled_code, Fregister_ccl_program)
5402 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
5403 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
5404 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
5405 contents are in range.
5406 (Fccl_execute_on_string): Check that status is in range.
5407 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
5408 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
5409 Accept and return EMACS_INT, not int, because callers can pass values
5411 (c_string_width, strwidth, lisp_string_width, chars_in_text)
5412 (multibyte_chars_in_text, parse_str_as_multibyte)
5413 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
5414 (str_as_unibyte, str_to_unibyte, string_count_byte8)
5415 (string_escape_byte8, Fget_byte):
5416 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5417 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
5418 avoid mishandling large integers.
5419 * character.h: Adjust decls to match defn changes elsewhere.
5420 * charset.c (load_charset_map_from_file, find_charsets_in_text)
5421 (Ffind_charset_region):
5422 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5423 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
5424 (load_charset_map_from_vector, Fdefine_charset_internal):
5425 Don't assume fixnum fits in int.
5426 (load_charset_map_from_vector, Fmap_charset_chars):
5427 Remove now-unnecessary CHECK_NATNUMs.
5428 (Fdefine_charset_internal): Check ranges here, more carefully.
5429 Don't rely on undefined behavior with signed left shift overflow.
5430 Don't assume unsigned int fits into fixnum, or that fixnum fits
5431 into unsigned int. Don't require max_code to be a valid fixnum;
5432 that's not true for gb10830 4-byte on a 32-bit host. Allow
5433 invalid_code to be a cons, for the same reason. Require code_offset
5434 to be a character. Avoid int overflow if max_char is close
5436 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
5437 this is intended anyway and avoids some undefined behavior.
5438 (load_charset_map): Pass unsigned, not int, as 2nd arg of
5439 INDEX_TO_CODE_POINT, as that's what it expects.
5440 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
5441 * charset.h (DECODE_CHAR): Return int, not unsigned;
5442 this is what was intended anyway, and it avoids undefined behavior.
5443 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
5444 integer-overflow issues.
5445 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
5446 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
5447 where the argument is EMACS_INT, and this behavior is not intended.
5448 * chartab.c (Fmake_char_table, Fset_char_table_range)
5449 (uniprop_get_decoder, uniprop_get_encoder):
5450 Don't assume fixnum fits in int.
5451 * cmds.c (move_point): New function, that does the gist of
5452 Fforward_char and Fbackward_char, but does so while checking
5453 for integer overflow more accurately.
5454 (Fforward_char, Fbackward_char): Use it.
5455 (Fforward_line, Fend_of_line, internal_self_insert)
5456 (internal_self_insert):
5457 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5458 Fix a FIXME, by checking for integer overflow when calculating
5459 target_clm and actual_clm.
5460 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
5461 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

6170 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
6172 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
6174 Assume C89 or later.
6175 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
6176 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
6178 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
6179 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
6180 * textprop.c, tparam.c (NULL): Remove.
6181 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
6182 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
6183 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6184 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6185 * xterm.c (input_signal_count): Assume volatile works.
6187 2012-05-21 Ken Brown <kbrown@cornell.edu>
6189 * xgselect.c (xg_select): Fix first argument in call to 'select'
6192 2012-05-20 Ken Brown <kbrown@cornell.edu>
6194 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6195 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6197 2012-05-19 Ken Brown <kbrown@cornell.edu>
6199 * xfns.c (x_in_use): Remove `static' qualifier.
6200 * xterm.h (x_in_use): Declare.
6201 * xgselect.c: Include xterm.h.
6202 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6203 and `display_arg' (bug#9754).
6205 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6207 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6209 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6210 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6212 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6214 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6216 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6217 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6219 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6220 reference to image_cache->refcount.
6221 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6223 2012-05-17 Juri Linkov <juri@jurta.org>
6225 * search.c (Fword_search_regexp, Fword_search_backward)
6226 (Fword_search_forward, Fword_search_backward_lax)
6227 (Fword_search_forward_lax): Move functions to isearch.el
6228 (bug#10145, bug#11381).
6230 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6232 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6234 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6236 * lread.c (init_obarray): Declare Qt and Qnil as special.
6238 2012-05-14 Glenn Morris <rgm@gnu.org>
6240 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6241 Put "libexec" before "bin", for the sake of init_callproc_1.
6243 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6245 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6247 * unexaix.c: Port to more-recent AIX compilers.
6248 (report_error, report_error_1, make_hdr, copy_sym)
6249 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6250 Make arguments const char *, not char *, to avoid violations of C
6251 standard and to fix some AIX warnings reported by Gilles Pion.
6253 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6255 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6256 already have overlays loaded.
6257 (handle_single_display_spec): Before returning without displaying
6258 fringe bitmap, synchronize the bidi iterator with the main display
6259 iterator, by calling iterate_out_of_display_property.
6260 (iterate_out_of_display_property): Detect buffer iteration by
6261 testing that it->string is a Lisp string.
6262 (get_next_display_element): When the current object is exhausted,
6263 and there's something on it->stack, call set_iterator_to_next to
6264 proceed with what's on the stack, instead of returning zero.
6265 (set_iterator_to_next): If called at the end of a Lisp string,
6266 proceed to consider_string_end without incrementing string
6267 position. Don't increment display vector index past the end of
6268 the display vector. (Bug#11417)
6269 (pos_visible_p): Don't report a position visible when move_it_to
6270 stopped at the last line of window, which happens to be scanned
6271 backwards by the bidi iteration. (Bug#11464)
6273 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6275 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6276 and right-margin display specs even if the spec is invalid or we
6277 are on a TTY, and thus unable to display on the fringes.
6278 That's because the text with the property will not be displayed anyway,
6279 so we need to signal to the caller that this is a "replacing"
6280 display spec. This fixes display when the spec is invalid or we
6283 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6285 * unexaix.c (make_hdr): Fix typo in prototype.
6286 This bug broke the build on AIX. Problem reported by Gilles Pion.
6288 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6290 * keyboard.c (kbd_buffer_get_event): Read special events also in
6291 batch mode. (Bug#11415)
6293 2012-05-12 Glenn Morris <rgm@gnu.org>
6295 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6297 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6299 * lisp.mk (lisp): Add newcomment.elc.
6301 2012-05-12 Glenn Morris <rgm@gnu.org>
6303 * Makefile.in (MKDIR_P): New, set by configure.
6304 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6306 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6308 Remove unused function hourglass_started.
6309 * dispextern.h (hourglass_started):
6310 * w32fns.c (hourglass_started):
6311 * xdisp.c (hourglass_started): Remove.
6313 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6315 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6316 Update dependencies.
6318 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6320 * xgselect.c (xg_select): Put maxfds+1 into a var.
6321 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6323 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6325 2012-05-10 Dave Abrahams <dave@boostpro.com>
6327 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6328 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6330 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6332 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6333 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6334 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6335 Initialize xd_registered_buses.
6337 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6339 Untag more efficiently if USE_LSB_TAG.
6340 This is based on a proposal by YAMAMOTO Mitsuharu in
6341 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6342 For an admittedly artificial (nth 8000 longlist) benchmark on
6343 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6344 Emacs's overall text size by 1%.
6345 * lisp.h (XUNTAG): New macro.
6346 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6347 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6348 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6349 * eval.c (Fautoload):
6350 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6351 * frame.h (XFRAME): Use XUNTAG.
6353 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6354 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6355 Remove unportable assumptions about print widths of types like
6357 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6358 intptr_t when converting between pointer and integer, to avoid GCC
6359 warnings about wrong width.
6361 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6363 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6364 stack for each reader_thread, instead of defaulting to 8MB
6365 determined by the linker. This avoids failures in creating
6366 subprocesses on Windows 7, see the discussion in this thread:
6367 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6369 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6371 Fix up display of the *Minibuf-0* buffer in the mini window.
6372 * keyboard.c (read_char): Don't clear the echo area if there's no
6374 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6375 contents of *Minibuf-0*) if there's no message displayed in its stead.
6377 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6379 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6382 2012-05-06 Chong Yidong <cyd@gnu.org>
6384 * lisp.mk (lisp): Update.
6386 2012-05-05 Jim Meyering <meyering@redhat.com>
6388 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
6390 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
6392 * data.c (PUT_ERROR): New macro.
6393 (syms_of_data): Use it. Add new error type `user-error'.
6394 * undo.c (user_error): New function.
6395 (Fprimitive_undo): Use it.
6396 * print.c (print_error_message): Adjust print style for `user-error'.
6397 * keyboard.c (user_error): New function.
6398 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
6400 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
6402 Do not limit current-time-string to years 1000..9999.
6403 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
6404 (Fcurrent_time_string): Support any year that is supported by the
6405 underlying localtime representation. Don't use asctime, as it
6406 has undefined behavior for years outside the range -999..9999.
6408 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
6410 Fix race conditions involving setenv, gmtime, localtime, asctime.
6411 Without this fix, interrupts could mess up code that uses these
6412 nonreentrant functions, since setting TZ invalidates existing
6413 tm_zone or tzname values, and since most of these functions return
6414 pointers to static storage.
6415 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
6416 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
6417 Grow the critical sections to include not just invoking
6418 localtime/gmtime, but also accessing these functions' results
6419 including their tm_zone values if any, and any related TZ setting.
6420 (format_time_string): Last arg is now struct tm *, not struct tm **,
6421 so that the struct tm is saved in the critical section.
6422 All callers changed. Simplify allocation of initial buffer, partly
6423 motivated by the fact that memory allocation needs to be outside
6424 the critical section.
6426 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
6428 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
6429 with RESET_INTERVAL.
6431 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6432 Remove duplicated buffer name initialization.
6434 2012-05-02 Jim Meyering <jim@meyering.net>
6436 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
6438 * xfns.c (x_window): Use xstrdup (Bug#11375).
6440 2012-05-02 Eli Zaretskii <eliz@gnu.org>
6442 * xdisp.c (pos_visible_p): If already at a newline from the
6443 display string before the 'while' loop, don't walk back the glyphs
6444 from it3.glyph_row. Solves assertion violation when the display
6445 string begins with a newline (egg.el). (Bug#11367)
6447 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
6449 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
6452 2012-05-01 Glenn Morris <rgm@gnu.org>
6454 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
6455 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
6456 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
6457 All were removed before 23.1.
6459 * dispnew.c: Remove HAVE_LIBNCURSES test;
6460 it is always true on relevant platforms.
6462 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
6463 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
6465 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
6467 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
6469 * .gdbinit (xpr): Remove checks for no longer existing misc types.
6470 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
6473 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
6475 Do not avoid creating empty evaporating overlays (Bug#9642).
6476 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
6477 That is, do not delete an evaporating overlay if it becomes
6478 empty after its bounds are adjusted to fit within its buffer.
6479 This fix caused other problems, and I'm reverting it until we get
6480 to the bottom of them.
6482 2012-04-27 Chong Yidong <cyd@gnu.org>
6484 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6486 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6488 * xdisp.c (pos_visible_p): If the window start position is beyond
6489 ZV, start the display from buffer beginning. Prevents assertion
6490 violation in init_iterator when the minibuffer window is scrolled
6493 * window.c (window_scroll_pixel_based): Likewise.
6495 2012-04-27 Chong Yidong <cyd@gnu.org>
6497 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6499 2012-04-27 Glenn Morris <rgm@gnu.org>
6501 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6502 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6504 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6506 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6507 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6509 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6511 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6512 display element, check also the underlying string or buffer
6513 character. (Bug#11341)
6515 * w32menu.c: Include w32heap.h.
6516 (add_menu_item): If the call to AppendMenuW (via
6517 unicode_append_menu) fails, disable Unicode menus only if we are
6518 running on Windows 9X/Me.
6520 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6522 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6523 (xgetint): Add missing shift for LSB tags.
6525 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6527 * keyboard.c (read_char): Don't wipe echo area for select window
6528 events: These might get delayed via `mouse-autoselect-window'
6531 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6533 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6534 manipulation of :loaded-from data.
6536 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6538 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6539 now a cons (bug#11311).
6541 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6543 Do not create empty overlays with the evaporate property (Bug#9642).
6544 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6545 if it becomes empty after its bounds are adjusted to fit within
6546 its buffer. Without this fix, in a nonempty buffer (let ((o
6547 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6548 yields an empty overlay that has the evaporate property, which is
6549 not supposed to happen.
6551 Fix minor GTK3 problems found by static checking.
6552 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6553 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6554 (struct _EmacsFixedClass, emacs_fixed_get_type):
6555 Move decls here from emacsgtkfixed.h, since they needn't be public.
6556 (emacs_fixed_get_type): Now static.
6557 (emacs_fixed_class_init): Omit unused local.
6558 (emacs_fixed_child_type): Remove; unused.

6560 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6561 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
6562 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6563 (EMACS_FIXED_GET_CLASS): Remove; unused.
6564 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6566 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6567 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6569 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6571 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
6572 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
6573 (__malloc_size_t, __malloc_ptrdiff_t):
6574 Remove. All uses removed, replaced by the definiens if needed,
6575 since we can assume C89 or better now.
6576 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
6577 (protect_malloc_state, align, get_contiguous_space)
6578 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
6579 (malloc_atfork_handler_child, malloc_enable_thread)

6584 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
6585 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
6586 Define using prototypes, not old style.
6587 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
6588 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
6589 (align): Don't assume that signed integer overflow wraps around.
6590 Omit unused local var.
6591 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
6592 (_free_internal_nolock, memalign, mallochook, reallochook):
6593 Omit no-longer-needed casts.
6594 (valloc): Use getpagesize, not __getpagesize.
6595 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
6596 (struct hdr): The 'magic' member is now size_t, not unsigned long.
6598 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
6600 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
6602 Move functions from C to Lisp. Make non-blocking method calls
6603 the default. Implement further D-Bus standard interfaces.
6605 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
6606 (QCdbus_request_name_allow_replacement)
6607 (QCdbus_request_name_replace_existing)
6608 (QCdbus_request_name_do_not_queue)
6609 (QCdbus_request_name_reply_primary_owner)

6612 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
6613 (QCdbus_registered_serial, QCdbus_registered_method)
6614 (QCdbus_registered_signal): New Lisp objects.
6615 (XD_DEBUG_MESSAGE): Use sizeof.

6617 (XD_DBUS_VALIDATE_BUS_ADDRESS, XD_DBUS_VALIDATE_OBJECT)
6618 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)

6651 * alloc.c: Handle unusual debugging option combinations.
6652 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
6653 since the two debugging options are incompatible.
6654 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
6656 (mem_init, mem_insert, mem_insert_fixup):
6657 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

6687 * print.c (print_preprocess): Only check print_depth if print-circle
6689 (print_object): Check for cycles even when print-circle is nil and
6690 print-gensym is t, but only check print_depth if print-circle is nil.
6692 2012-04-20 Chong Yidong <cyd@gnu.org>
6694 * process.c (wait_reading_process_output): If EIO occurs on a pty,
6695 set the status to "failed" and ensure that sentinel is run.

6710 farther than the first row after the header line, if any.
6711 Don't consider the header-line row as "partially visible", even if

6750 New extern decls, to avoid calling undeclared functions.
6751 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
6752 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
6753 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

6755 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
6756 Remove one incorrect comment and fix another.

6770 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
6771 Remove decls. This fixes an "It stinks!".

6775 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
6777 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

6793 * s/netbsd.h, s/sol2-6.h:
6794 Remove definition of GC_MARK_STACK, since the default now works.
6795 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
6796 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
6797 no longer the default.
6798 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
6800 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
6802 * lread.c (lisp_file_lexically_bound_p):

6823 2012-04-11 Daniel Colascione <dancol@dancol.org>
6825 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
6826 against is gone. It's better to use vfork now so that when Cygwin
6827 gains a new, working vfork, we use it automatically (bug#10398).
6829 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

6850 being loaded (bug#10424).
6852 2012-04-09 Glenn Morris <rgm@gnu.org>
6854 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
6855 not just in the obarray, before snarfing them. (Bug#11036)

6882 * minibuf.c (Fread_variable): Callers changed.
6884 2012-04-09 Eli Zaretskii <eliz@gnu.org>
6886 * xdisp.c (set_cursor_from_row): If the display string appears in
6887 the buffer at position that is closer to point than the position
6888 after the display string, display the cursor on the first glyph of
6889 the display string. Fixes cursor display when a 'display' text
6890 property immediately follows invisible text. (Bug#11094)
6892 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
6894 composite.c: use 'double' consistently
6895 * composite.c (get_composition_id): Use 'double' consistently
6896 instead of converting 'float' to 'double' and vice versa; this is
6897 easier to understand and avoids a GCC warning.
6899 2012-04-09 Glenn Morris <rgm@gnu.org>
6901 * Makefile.in: Generate leim-list with bootstrap-emacs, in
6902 preparation for dumping it with emacs. (Bug#4789)

6924 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
6925 (mark_memory): Mark Lisp_Objects only if pointers might hide in

6944 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
6945 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6946 [!WINDOWSNT]: New macros.
6947 (init_libxml2_functions, libxml2_loaded_p): New functions.
6948 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6949 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6950 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6951 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6953 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6954 Call init_libxml2_functions before calling libxml2 functions.
6955 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6957 * emacs.c: Don't include libxml/parser.h.

6959 xmlCleanupParser directly.
6961 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6963 2012-04-07 Eli Zaretskii <eliz@gnu.org>

6971 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6972 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6973 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6974 macros related to unification of CJK characters. For the details,
6975 see the discussion following the message here:
6976 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6978 2012-04-04 Chong Yidong <cyd@gnu.org>
6980 * keyboard.c (Vdelayed_warnings_list): Doc fix.

6992 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6994 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6995 position we get to after a call to move_it_to fails the
6996 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6997 only if we wind up in a string from display property. (Bug#11063)
6999 * window.c (Fdelete_other_windows_internal): Invalidate the row
7000 and column information about mouse highlight, so that redisplay
7001 restores it after reallocating the glyph matrices. (Bug#7464)
7003 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7004 string comes from a `display' text property, use the buffer
7005 position of that property as if we actually saw that position in
7007 (move_it_by_lines): Remove the assertion that
7008 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7009 violated when there's a before-string at the beginning of a line.
7012 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7014 * xdisp.c (append_space_for_newline): If the default face was
7015 remapped, use the remapped face for the appended newline.
7016 (extend_face_to_end_of_line): Use the remapped default face for
7017 extending the face to the end of the line.
7018 (display_line): Call extend_face_to_end_of_line when the default
7019 face was remapped. (Bug#11068)

7045 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7047 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

7054 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7056 * s/ms-w32.h (tzname): Include time.h before redirecting to

7067 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7069 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7070 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7071 when fetching a multibyte character consumes more bytes than
7072 CHAR_BYTES returns, due to unification of CJK characters in
7073 string_char. (Bug#11073)
7075 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7077 * process.c (wait_reading_process_output): Handle pty disconnect
7078 by refraining from sending oneself a SIGCHLD (bug#10933).

7095 * w32proc.c (Fw32_set_console_codepage)
7096 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
7099 2012-03-20 Chong Yidong <cyd@gnu.org>
7101 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7102 to reflect default non-nil value of redisplay-dont-pause.
7104 2012-03-19 Kenichi Handa <handa@m17n.org>
7106 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
7107 it fit in a valid range (Bug#11003).
7109 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7111 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7112 that is not from display property, accept the row as a "cursor
7113 row" if one of the string's character has a non-nil `cursor'
7114 property. Fixes cursor positioning when there are newlines in
7115 overlay strings, e.g. in icomplete.el. (Bug#11035)
7117 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

7148 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7151 2012-03-03 Glenn Morris <rgm@gnu.org>
7153 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

7161 (redisplay_window): Pass to move_it_vertically the margin in
7162 pixels, not in screen lines.
7164 2012-03-02 Glenn Morris <rgm@gnu.org>
7166 * buffer.c (buffer-list-update-hook): Doc fix.
7168 2012-02-29 Eli Zaretskii <eliz@gnu.org>

7171 push_it before setting up the iterator for the first overlay
7172 string, even if we have an empty string loaded.
7173 (next_overlay_string): If there's an empty string on the iterator
7174 stack, pop the stack. (Bug#10903)
7176 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7178 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7179 Suggested by Stefan Monnier in
7180 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7181 * alloc.c (widen_to_Lisp_Object): New static function.
7182 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7183 and widening them to Lisp_Objects. This would work even if
7184 USE_LSB_TAG is defined and wide integers are used, which might
7185 happen in a future version of Emacs.
7187 2012-02-25 Chong Yidong <cyd@gnu.org>
7189 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

7198 * keyboard.c (process_special_events): Handle all X selection
7199 requests in kbd_buffer, not just the next one (Bug#8869).
7201 2012-02-23 Chong Yidong <cyd@gnu.org>
7203 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7204 call when setting menu-bar-lines and tool-bar-lines parameters.
7205 (unwind_create_frame_1): New helper function.
7207 * window.c (inhibit_window_configuration_change_hook): New var.
7208 (run_window_configuration_change_hook): Obey it.
7209 (syms_of_window): Initialize it.
7211 2012-02-22 Chong Yidong <cyd@gnu.org>

7226 when computing $valmask.
7228 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7229 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7230 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7231 It's useless in that case, and it can cause problems on hosts
7232 that allocate halves of EMACS_INT values separately.
7233 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7234 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7235 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7236 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7237 it avoids undefined behavior on hosts where shifting right by more
7238 than the word width has undefined behavior.
7240 2012-02-19 Chong Yidong <cyd@gnu.org>
7242 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7243 (Funhandled_file_name_directory, Ffile_name_as_directory)
7244 (Fdirectory_file_name, Fexpand_file_name)

7262 2012-02-15 Chong Yidong <cyd@gnu.org>
7264 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7265 marked as special. Also, starting docstrings with * is obsolete.
7267 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

7280 2012-02-12 Chong Yidong <cyd@gnu.org>
7282 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
7283 as that creates a dangerous corner case.
7285 * window.c (Fdelete_window_internal): Invalidate the mouse
7286 highlight (Bug#9904).
7288 2012-02-12 Glenn Morris <rgm@gnu.org>

7293 * nsselect.m (Fx_own_selection_internal)
7294 (Fx_disown_selection_internal, Fx_selection_exists_p)
7295 (Fx_selection_owner_p, Fx_get_selection_internal):
7296 Sync docs and argument specs with the xselect.c versions.

7318 2012-02-07 Chong Yidong <cyd@gnu.org>
7320 * buffer.c (Fbuffer_local_variables)
7321 (buffer_lisp_local_variables): Handle unbound vars correctly;
7322 don't let Qunbound leak into Lisp.
7324 2012-02-07 Glenn Morris <rgm@gnu.org>
7326 * image.c (Fimagemagick_types): Doc fix.
7328 * image.c (imagemagick-render-type): Change it from a lisp object
7329 to an integer. Move the doc here from the lisp manual.

7334 * doc.c (store_function_docstring): Avoid applying docstring of
7335 alias to base function (Bug#2603).

7361 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7363 Handle overflow when computing char display width (Bug#9496).
7364 * character.c (char_width): Return EMACS_INT, not int.
7365 (char_width, c_string_width): Check for overflow when
7366 computing the width; this is possible now that individual
7367 characters can have unbounded width. Problem introduced
7368 by merge from Emacs 23 on 2012-01-19.
7370 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7399 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
7400 first 2 arguments are identical. This makes inserting large
7401 output from a subprocess an order of magnitude faster on
7402 MS-Windows, where all sbrk'ed memory is always contiguous.

7508 emacs: fix an auto-save permissions race condition (Bug#10400)
7509 * fileio.c (auto_saving_dir_umask): New static var.
7510 (Fmake_directory_internal): Use it.
7511 (do_auto_save_make_dir): Set it, instead of invoking chmod after
7512 creating the directory. The old code temporarily assigns
7513 too-generous permissions to the directory.
7514 (do_auto_save_eh): Clear it.
7515 (Fdo_auto_save): Catch all errors, not just file errors, so
7516 that the var is always cleared.

7573 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
7574 property that ends at ZV, so that the bidi iteration could be

8022 is set, removing the need for VIRT_ADDRESS_VARIES.
8023 (PURE_P): Use a more-efficient implementation that needs just one

8026 to 4 (xorl, subq, cmpq, setbe).

8039 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8040 behave as if the cursor position were at the window margin.
8042 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8043 and the cursor position is out of bounds, behave as if the cursor
8044 position were at the window margin. (Bug#10075)
8046 2011-11-18 Chong Yidong <cyd@gnu.org>
8048 * window.c (Fwindow_combination_limit): Make first argument

8071 (compute_line_metrics): Call row_hash, instead of computing the
8074 * dispnew.c (verify_row_hash): Call row_hash for computing the
8075 hash code of a row, instead of duplicating code from xdisp.c.
8077 * dispextern.h (row_hash): Add prototype.
8079 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
8081 * frame.c (delete_frame): Don't delete the terminal when the last

8270 (static_offset_intervals): Remove.
8271 (offset_intervals): Rewrite using the old contents of
8272 static_offset_intervals. The old version didn't conform to C99

8296 (Fwindow_vscroll): Doc fix.
8297 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
8298 argument, since it makes no sense to pass a live window and for

8561 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
8563 * keyboard.c (test_undefined): New function (bug#9751).
8564 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
8566 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
8568 * sysdep.c (init_sys_modes): Fix the check for the controlling
8569 terminal (Bug#6649).
8571 2011-10-20 Eli Zaretskii <eliz@gnu.org>
8573 * dispextern.h (struct bidi_it): New member next_en_type.
8575 * bidi.c (bidi_line_init): Initialize the next_en_type member.
8576 (bidi_resolve_explicit_1): When next_en_pos is valid for the
8577 current character, check also for next_en_type being WEAK_EN.
8578 (bidi_resolve_weak): Don't enter the expensive loop if the current
8579 position is before next_en_pos. Record the bidi type of the first
8580 non-ET, non-BN character we find, in addition to its position.
8581 (bidi_level_of_next_char): Invalidate next_en_type when
8582 next_en_pos is over-stepped.
8584 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
8586 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
8587 * editfns.c: Rewrite current-time-zone so that it invokes
8588 the equivalent of (format-time-string "%Z") to get the time zone name.
8589 This fixes a bug when the time zone name contains characters that
8590 need converting from the system time locale to Emacs internal format.
8591 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
8592 that patch fixed format-time-string to do the conversion, but
8593 I forgot to fix current-time-zone.
8594 (format_time_string): New function, containing most of
8595 what Fformat_time_string used to contain.
8596 (Fformat_time_string): Rewrite in terms of format_time_string.
8597 This doesn't change this function's behavior.
8598 (current-time-zone): Rewrite to use format_time_string.
8599 This fixes the bug reported by Michael Schierl in
8600 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
8601 Jason Rumney's 2007-06-07 change worked around this bug, but
8603 * systime.h (tzname, timezone): Remove no-longer-used declarations.
8605 2011-10-19 Eli Zaretskii <eliz@gnu.org>
8607 * xdisp.c (start_display): If the character at POS is displayed
8608 via a display vector, reset IT->current.dpvec_index to zero.
8609 (try_window_reusing_current_matrix): If a line ends in a display
8610 vector or the next line starts in a display vector, continue
8611 redrawing the window even though the character position of
8612 start_row was reached.
8615 2011-10-18 Chong Yidong <cyd@gnu.org>
8617 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
8618 with nobreak-char-display too.
8620 2011-10-18 Eli Zaretskii <eliz@gnu.org>
8622 Fix part 3 of bug#9771.
8623 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
8624 (bidi_resolve_neutral): Don't enter the expensive loop looking for
8625 non-neutral characters if the current character is a paragraph
8626 separator (a.k.a. Newline). This avoids running the same
8627 expensive loop twice, once when we consume the preceding newline
8628 and the other time when the line actually needs to be displayed.
8629 Avoid the loop when we see neutrals on the base embedding level
8630 following a character whose directionality is the same as the
8631 paragraph's. This avoids running the expensive loop when a line
8632 ends in a long sequence of neutrals, like control characters.
8633 Add assertion against STRONG_AL type. Slightly rearrange code
8634 that determines the type of a neutral given the first non-neutral
8636 (bidi_level_of_next_char): Set next_en_pos to zero when
8637 invalidating its info.
8639 2011-10-17 Eli Zaretskii <eliz@gnu.org>
8641 * xdisp.c (push_display_prop): Determine whether to record string
8642 or buffer position by IT->string, not by IT->method. Allow
8643 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
8644 (move_it_vertically_backward): Don't look for character position
8645 immediately after the newline when in a continuation line.
8648 2011-10-15 Martin Rudalics <rudalics@gmx.at>
8650 * window.c (coordinates_in_window): Rewrite and delabelize
8651 vertical border check. (Bug#5357) (Bug#9618)
8653 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
8655 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
8656 errors in XSetWindowBorder (bug#9310).
8658 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
8660 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
8661 avoid crash when xmalloc overrun checking is enabled.
8663 2011-10-13 Eli Zaretskii <eliz@gnu.org>
8665 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
8666 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
8667 cursor motion with <left> and <right> arrow keys.
8669 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
8670 some callers set that themselves.
8672 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8674 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
8675 display string and the previous row comes from the same string and
8676 is empty. (Bug#9739) (Bug#9738)
8678 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
8680 * doc.c (get_doc_string): Encode file name (bug#9735).
8682 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8684 * bidi.c (bidi_level_of_next_char):
8685 * xdisp.c (get_visually_first_element): Remove old incorrect
8686 comments regarding the Unicode Line Separator character.
8688 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
8690 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
8692 * alloc.c (Fgc_status): Do not access beyond zombies array
8693 boundary if nzombies > MAX_ZOMBIES.
8694 * alloc.c (dump_zombies): Add missing format specifier.
8696 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
8698 * xdisp.c (set_cursor_from_row): Simplify conditionals,
8699 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
8701 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
8702 Some packages use them to denote characters with modifiers.
8704 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
8706 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
8707 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
8708 matching a pp-number. Rename parameter var to var1.
8710 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
8712 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
8714 2011-10-08 Glenn Morris <rgm@gnu.org>
8716 * callint.c (Fcall_interactively): Give a more explicit error for the
8717 'c' case with a non-character input. (Bug#8479)
8719 2011-10-08 Eli Zaretskii <eliz@gnu.org>
8721 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
8723 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
8724 lines that are hscrolled on the left.
8726 * dispnew.c (buffer_posn_from_coords): Account for a possible
8727 presence of header-line. (Bug#4426)
8729 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
8731 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
8732 Don't advertise functionality which we discourage or doesn't work.
8734 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
8736 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
8737 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
8738 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
8739 this makes Emacs dump core during garbage collection on rare
8740 occasions. sizeof is obviously inferior to offsetof here, so
8741 stick with offsetof.
8742 (GC_POINTER_ALIGNMENT): New macro.
8743 (mark_memory): Omit 3rd (offset) arg; caller changed.
8744 Don't assume EMACS_INT alignment is the same as pointer alignment.
8746 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
8748 * keyboard.c (read_key_sequence_remapped): New var.
8749 (read_key_sequence): Compute remapping in the right buffer.
8750 (command_loop_1): Use read_key_sequence's remapping directly.
8752 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
8754 * dired.c (file_name_completion): Don't expand file name.
8755 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
8756 before checking file name handler.
8758 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
8759 they've been requested explicitly (bug#9591).
8761 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
8763 * keymap.c (Fsingle_key_description): Use make_specified_string
8764 instead of build_string to build string from push_key_description.
8767 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8769 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
8770 This fixes a Y2038 bug on 64-bit hosts.
8771 * buffer.c (reset_buffer):
8772 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
8773 (Fclear_buffer_auto_save_failure):
8774 Use 0, not -1, to represent an unset failure time, since time_t
8775 might not be signed.
8777 Remove dependency on glibc malloc internals.
8778 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8779 Move back here from lisp.h, but with their new implementations.
8780 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8781 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
8782 * charset.c (charset_table_init): New static var.
8783 (syms_of_charset): Use it instead of xmalloc. This removes a
8784 dependency on glibc malloc internals. See Eli Zaretskii's comment in
8785 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
8786 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8787 Move back to alloc.c.
8788 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8789 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
8791 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
8793 * nsterm.m (windowDidResize): Call x_set_window_size only when
8794 ns_in_resize is true. Otherwise set pixelwidth/height and
8795 call change_frame_size (Bug#9628).
8797 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8799 Port --enable-checking=all to Fedora 14 x86-64.
8800 * charset.c (syms_of_charset): Also account for glibc malloc's
8801 internal overhead when calculating the initial malloc maximum.
8803 Port --enable-checking=all to Fedora 14 x86.
8804 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8806 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
8807 (overrun_check_realloc, overrun_check_free):
8808 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
8809 That way, xmalloc returns a properly-aligned pointer even if
8810 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
8811 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
8812 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
8813 into account when calculating the initial malloc maximum.
8814 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8815 Move here from alloc.c, so that charset.c can use it too.
8816 Properly align; the old code wasn't right for common 32-bit hosts
8817 when configured with --enable-checking=all.
8818 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8819 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
8821 2011-09-29 Eli Zaretskii <eliz@gnu.org>
8823 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
8826 2011-09-28 Eli Zaretskii <eliz@gnu.org>
8828 * xdisp.c (compute_display_string_end): If there's no display
8829 string at CHARPOS, return -1.
8831 * bidi.c (bidi_fetch_char): When compute_display_string_end
8832 returns a negative value, treat the character as a normal
8833 character not covered by a display string. (Bug#9624)
8835 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
8837 * lread.c (Fread_from_string): Fix typo in docstring.
8839 2011-09-27 Eli Zaretskii <eliz@gnu.org>
8841 * xdisp.c (handle_invisible_prop): If invisible text ends on a
8842 newline, reseat the iterator instead of bidi-iterating there one
8843 character at a time. (Bug#9610)
8844 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
8845 TO_CHARPOS if the bidi iterator is at base embedding level.
8847 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
8849 * lread.c (readevalloop): Use correct code for NBSP.
8850 (read1): Likewise. (Bug#9608)
8852 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
8854 * dbusbind.c (Fdbus_register_signal): When service is not
8855 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
8857 2011-09-25 Glenn Morris <rgm@gnu.org>
8859 * buffer.c (truncate-lines): Doc fix.
8861 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
8863 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
8864 (Fset_window_next_buffers): Doc fix.
8866 2011-09-24 Glenn Morris <rgm@gnu.org>
8868 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
8870 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
8872 Fix minor problems found by static checking.
8873 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
8874 * indent.c (Fvertical_motion): Fix == vs = typo.
8876 2011-09-24 Eli Zaretskii <eliz@gnu.org>
8878 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
8879 Default value is now t. Doc fix.
8881 * indent.c (Fvertical_motion): Compute and apply the overshoot
8882 logic when moving up, not only when moving down. Fix the
8883 confusing name and values of the it_overshoot_expected variable;
8884 logic changes accordingly. (Bug#9254) (Bug#9549)
8886 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
8887 CHARPOS is covered by a display string which includes newlines.
8888 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
8889 is covered by a display string with embedded newlines.
8891 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
8893 * dbusbind.c (Fdbus_register_signal): Add match rule to
8894 Vdbus_registered_objects_table. (Bug#9581)
8895 (Fdbus_register_method, Vdbus_registered_objects_table):
8898 2011-09-24 Jim Meyering <meyering@redhat.com>
8900 do not ignore write error for any output size
8901 The previous change was incomplete.
8902 While it makes emacs --batch detect the vast majority of stdout
8903 write failures, errors were still ignored whenever the output size is
8904 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
8905 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
8906 && echo FAIL: ignored write error
8907 FAIL: ignored write error
8908 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
8909 && echo FAIL: ignored write error
8910 FAIL: ignored write error
8911 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
8913 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
8915 * emacs.c (Fkill_emacs): In noninteractive mode exit
8916 non-successfully if a write error occurred on stdout. (Bug#9574)
8918 2011-09-21 Eli Zaretskii <eliz@gnu.org>
8920 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
8923 * dispextern.h (struct it): Update the comment documenting what
8926 2011-09-20 Eli Zaretskii <eliz@gnu.org>
8928 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
8929 a display string, extend search for cursor position to end of row.
8930 (find_row_edges): If the row ends in a newline from a display
8931 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8932 Handle the case of a display string with multiple newlines.
8933 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8934 non-empty line. Fixes confusing cursor motion with arrow keys at
8935 the beginning of a line that starts with whitespace.
8937 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8939 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
8942 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
8944 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
8947 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8949 * xdisp.c (display_line): Record maximum and minimum buffer
8950 positions even if no glyphs were produced (e.g., by a zero-width
8951 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8952 buffer positions that will be removed from the glyph row because
8954 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8955 column is beyond frame width: don't subtract 1 "pixel" when
8956 computing width of the stretch.
8957 (reseat_at_next_visible_line_start): Undo the change made on
8958 2011-09-17 that saved paragraph information and restored it after
8959 the call to `reseat'. (Bug#9545)
8961 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8963 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8964 and turn window cursor on if cleared (Bug#9415).
8966 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
8968 * search.c (boyer_moore): Take unibyte characters from pattern
8969 literally. (Bug#9458)
8971 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8973 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
8975 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
8977 Fix minor problem found by static checking.
8978 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8979 initialized, to pacify gcc -Wuninitialized.
8981 * fileio.c: Report proper errno when syscall falls.
8982 (Finsert_file_contents): Save and restore errno,
8983 so that report_file_error outputs the correct diagnostic.
8984 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8986 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8988 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8990 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8992 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8993 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8995 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8997 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8998 about the current paragraph and restore it after the call to reseat.
9000 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9001 (bidi_find_paragraph_start): Search back for paragraph beginning
9002 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9003 (bidi_move_to_visually_next): Only trigger paragraph-related
9004 computations when the last character is a newline or at EOB, not
9005 just any NEUTRAL_B. (Bug#9470)
9007 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9008 truncated lines if point is covered by a display string. (Bug#9524)
9010 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9012 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9013 (cons_to_x_long): New function.
9014 (lisp_data_to_selection_data): Use it. Correct the test for
9015 short-versus-long data; it was negated. Break out of vector
9016 loop, for efficiency, when a long datum is discovered.
9018 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9020 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9022 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9024 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

9029 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9030 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9032 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9034 * editfns.c (Fformat): Correctly handle text properties on "%%".

9043 (fill_composite_glyph_string): Add comments about special meaning
9044 of TAB characters in a composition.
9046 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9048 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9049 This occurs when processing a multibyte format.
9050 Problem reported by Wolfgang Jenker.
9052 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9054 * xdisp.c (try_cursor_movement): Only check for exact match if
9055 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9057 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9059 Remove unused external symbols.
9060 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9061 * xdisp.c (calc_pixel_width_or_height): Now static.
9062 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9063 * indent.c (check_display_width):
9064 * w32term.c: Fix comment to match code.
9065 * xterm.c, xterm.h (x_catching_errors): Remove.
9067 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9069 * xselect.c: Use signed conversions more consistently (Bug#9498).
9070 (selection_data_to_lisp_data): Assume incoming selection data are
9071 signed integers, not unsigned. This is to be consistent with
9072 outgoing selection data, which was modified to use signed integers
9073 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9074 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9075 expects long, not unsigned long.
9077 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9079 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9080 computation of loop end. Reported by Johan Bockgård
9083 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9085 * frame.c (Fother_visible_frames_p): Function deleted.
9087 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9089 * indent.c (compute_motion): Process display vector front to back
9090 rather than the other way around. (Bug#2496)
9092 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9094 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9096 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9098 * minibuf.c (Fread_from_minibuffer): Doc fix.
9100 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9102 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9103 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9105 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9107 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9108 value for non-existent files.
9110 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9112 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9113 set its "size" to -1. This will set the modtime_size field of
9114 the corresponding buffer to -1, which is what
9115 verify-visited-file-modtime expects for files that do not exist.
9118 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9120 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9122 * lisp.h: ... from here. push_key_description is no longer
9123 defined in keyboard.c, so its declaration should not be in
9124 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9125 logically belongs with push_key_description.
9127 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9129 * buffer.h: Include <sys/types.h> instead of <time.h>.
9130 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9131 Problem reported by Herbert J. Skuhra.
9133 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9135 * xml.c (parse_region): Make the parsing work for
9136 non-comment-starting XML files again (bug#9144).
9138 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9140 * image.c (gif_load): Fix calculation of bottom and right corner.
9143 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9145 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9146 redisplay in small windows.
9148 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9150 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9152 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9154 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9155 Operate on live windows only.
9157 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

9161 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9163 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9164 only under bidi iteration.
9166 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9168 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9170 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9172 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9173 Without this fix, the command to link temacs failed due to an
9174 undefined symbol __builtin_isnan. This is because
9175 /usr/include/iso/math_c99.h #defines isnan(x) to
9176 __builtin_isnan(x), but the bundled gcc, which identifies itself
9177 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9179 * floatfns.c (isnan): #undef, and then #define to a clone of
9181 (Fisnan): Always define, since it's always available now.
9182 (syms_of_floatfns): Always define isnan at the Lisp level.
9184 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9186 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9188 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9190 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9191 The previous code assumed that file offsets (off_t values) fit in
9192 EMACS_INT variables, which is not true on typical 32-bit hosts.
9193 The code messed up by falsely reporting buffer overflow in cases
9194 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9195 when "big" contains more than 2**29 bytes, even though this
9196 inserts just one byte and does not overflow the buffer.
9197 (Finsert_file_contents): Store file offsets as off_t
9198 values, not as EMACS_INT values. Check for overflow when
9199 converting between EMACS_INT and off_t. When checking for
9200 buffer overflow or for overlap, take the offsets into account.
9201 Don't use EMACS_INT for small values where int suffices.
9202 When checking for overlap, fix a typo: ZV was used where
9203 ZV_BYTE was intended.
9204 (Fwrite_region): Don't assume off_t fits into 'long'.
9205 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9207 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9209 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9211 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9213 sprintf-related integer and memory overflow issues (Bug#9412).
9215 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9216 (esprintf, exprintf, evxprintf): New functions.
9217 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9218 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9219 (modify_event_symbol): Do not assume that the length of
9220 name_alist_or_stem is safe to alloca and fits in int.
9221 (Fexecute_extended_command): Likewise for function name and binding.
9222 (Frecursion_depth): Wrap around reliably on integer overflow.
9223 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9224 since some callers pass EMACS_INT values.
9225 (Fsingle_key_description): Don't crash if symbol name contains more
9226 than MAX_ALLOCA bytes.
9227 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9228 (get_minibuffer): Arg is now EMACS_INT, not int.
9229 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9230 (esprintf, exprintf, evxprintf): New decls.
9231 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9233 * dbusbind.c (signature_cat): New function.
9234 (xd_signature, Fdbus_register_signal):
9235 Do not overrun buffer; instead, report string overflow.
9237 * dispnew.c (add_window_display_history): Don't overrun buffer.
9238 Truncate instead; this is OK since it's just a log.
9240 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9241 even if the time zone offset is outlandishly large.
9242 Don't mishandle offset == INT_MIN.
9244 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9245 when creating daemon; the previous buffer-overflow check was incorrect.
9247 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9248 which has the guts of the old verror function.
9250 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9251 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9253 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9254 (font_unparse_xlfd): Don't blindly alloca long strings.
9255 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9256 fits in int, when using sprintf. Use single snprintf to count
9257 length of string rather than counting it via multiple sprintfs;
9258 that's simpler and more reliable.
9259 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9260 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9261 sprintf, in case result does not fit in int.
9263 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9264 (fontset_from_font): Print it.
9266 * frame.c (tty_frame_count): Now printmax_t, not int.
9267 (make_terminal_frame, set_term_frame_name): Print it.
9268 (x_report_frame_params): In X, window IDs are unsigned long,
9269 not signed long, so print them as unsigned.
9270 (validate_x_resource_name): Check for implausibly long names,
9271 and don't assume name length fits in 'int'.
9272 (x_get_resource_string): Don't blindly alloca invocation name;
9273 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9276 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9277 (xg_check_special_colors, xg_set_geometry):
9278 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9280 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9281 Use esprintf, not sprintf, in case result does not fit in int.
9283 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9284 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9285 it as a large positive number.
9286 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9287 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9289 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9290 in case result does not fit in int.
9292 * print.c (float_to_string): Detect width overflow more reliably.
9293 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9294 buffer overrun. Don't assume list length fits in 'int'. Treat
9295 print length of 0 as 0, not as infinity; to be consistent with other
9296 uses of print length in this function. Don't overflow print length
9297 index. Don't assume hash table size fits in 'long', or that
9298 vectorlike size fits in 'unsigned long'.
9300 * process.c (make_process): Use printmax_t, not int, to format
9301 process-name gensyms.
9303 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9305 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9306 to avoid potential buffer overrun.
9308 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9309 if X resource line is longer than 512 bytes.
9311 * xfns.c (x_window): Make sprintf buffer a bit bigger
9312 to avoid potential buffer overrun.
9314 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9316 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9318 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9320 Integer overflow fixes for scrolling, etc.
9321 Without these, Emacs silently mishandles large integers sometimes.
9322 For example, "C-u 4294967297 M-x recenter" was treated as if
9323 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9325 * xdisp.c (try_window_id): Check Emacs fixnum range before
9326 converting to 'int'.
9328 * window.c (window_scroll_line_based, Frecenter):
9329 Check that an Emacs fixnum is in range before assigning it to 'int'.
9330 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9331 values converted from Emacs fixnums.
9332 (Frecenter): Don't wrap around a line count if it is out of 'int'
9333 range; instead, treat it as an extreme value.
9334 (Fset_window_configuration, compare_window_configurations):
9335 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9337 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9338 that can exceed INT_MAX. Check that EMACS_INT value is in range
9339 before assigning it to the (possibly-narrower) index.
9340 (match_limit): Don't assume that a fixnum can fit in 'int'.
9342 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9345 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9346 (Fvertical_motion): Don't wrap around LINES values that don't fit
9347 in 'int'. Instead, treat them as extreme values. This is good
9348 enough for windows, which can't have more than INT_MAX lines anyway.
9350 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9352 * Require libxml/parser.h to avoid compilation warning.
9354 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9356 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9357 since this reportedly can destroy thread storage.
9359 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9361 * syntax.c (find_defun_start): Update all cache variables if
9362 exiting early (Bug#9401).
9364 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9366 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9368 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9369 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9370 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9372 * term.c (tty_append_glyph): New function.
9373 (produce_stretch_glyph): Static function and its prototype deleted.
9375 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9378 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9380 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9381 when checking :margin (Bug#9390).
9382 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9383 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9384 so that the name doesn't mislead. All uses changed.
9386 2011-08-28 Johan Bockgård <bojohan@gnu.org>
9388 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
9391 2011-08-27 Eli Zaretskii <eliz@gnu.org>
9393 * xdisp.c (move_it_to): Don't bail out early when reaching
9394 position beyond to_charpos, if we are scanning backwards.
9395 (move_it_vertically_backward): When DY == 0, make sure we get to
9396 the first character in the line after the newline.
9398 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
9400 * ccl.c: Improve and simplify overflow checking (Bug#9196).
9401 (ccl_driver): Do not generate an out-of-range pointer.
9402 (Fccl_execute_on_string): Remove unnecessary check for
9403 integer overflow, noted by Stefan Monnier in
9404 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
9405 Remove a FIXME that didn't need fixing.
9406 Simplify the newly-introduced buffer reallocation code.
9408 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
9410 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
9412 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
9414 Integer and memory overflow issues (Bug#9196).
9416 * doc.c (get_doc_string): Rework so that
9417 get_doc_string_buffer_size is the actual buffer size, rather than
9418 being 1 less than the actual buffer size; this makes xpalloc more
9421 * image.c (x_allocate_bitmap_record, cache_image):
9422 * xselect.c (Fx_register_dnd_atom):
9423 Simplify previous changes by using xpalloc.
9425 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
9426 since either will do and ptrdiff_t is convenient with xpalloc.
9428 * charset.c (charset_table_size)
9429 (struct charset_sort_data.priority): Now ptrdiff_t.
9430 (charset_compare): Don't overflow if priorities differ greatly.
9431 (Fsort_charsets): Don't assume list length fits in int.
9432 Check for size-calculation overflow when allocating sort data.
9433 (syms_of_charset): Allocate an initial charset table that is
9434 just under 64 KiB, to avoid problems with glibc malloc and mmap.
9436 * cmds.c (internal_self_insert): Check for size-calculation overflow.
9438 * composite.h (struct composition.glyph_len): Now int, not unsigned.
9439 The actual value is always <= INT_MAX, and leaving it unsigned made
9440 overflow checking harder.
9442 * dispextern.h (struct glyph_matrix.rows_allocated)
9443 (struct face_cache.size): Now ptrdiff_t, for convenience in use
9444 with xpalloc. The values are still always <= INT_MAX.
9446 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
9448 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
9449 (SAFE_NALLOCA): New macro.
9451 * region-cache.c (struct boundary.pos, find_cache_boundary)
9452 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
9453 (set_cache_region, invalidate_region_cache)
9454 (revalidate_region_cache, know_region_cache, region_cache_forward)
9455 (region_cache_backward, pp_cache):
9456 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
9457 so that ptrdiff_t * can be passed to xpalloc.
9458 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
9459 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
9460 (pp_cache): Don't assume cache_len fits in int.
9461 * region-cache.h: Adjust extern decls to match.
9463 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
9464 EMACS_INT, since either will do, for xpalloc.
9466 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
9467 (xnmalloc, xnrealloc, xpalloc): New functions.
9469 * bidi.c (bidi_shelve_header_size): New constant.
9470 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
9471 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
9473 * bidi.c (bidi_cache_shrink):
9474 * buffer.c (overlays_at, overlays_in, record_overlay_string)
9476 Don't update size of array until after memory allocation succeeds,
9477 because xmalloc/xrealloc may not return.
9478 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9479 now that we have proper integer overflow checking.
9480 (record_overlay_string, overlay_strings): Catch overflows when
9481 calculating size of overlay_str_buf.
9483 * callproc.c (Fcall_process): Check for size overflow when
9484 calculating size of args2.
9485 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
9486 Normally we prefer signed values, but sticking with ptrdiff_t would
9487 require adding more-complicated checks.
9489 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
9490 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
9491 Redo buffer-overflow calculations to avoid integer overflow.
9492 Add a FIXME comment where memory seems to be over-allocated.
9494 * character.c (Fstring): Check for size-calculation overflow.
9496 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
9497 unnecessary integer overflow. Check for size overflow.
9498 (encode_coding_object): Don't update size until xmalloc succeeds.
9500 * composite.c (get_composition_id): Check for overflow in glyph
9501 length calculations.
9503 Integer and memory overflow fixes for display code.

9532 * emacs.c (main): Do not reallocate argv, since there is a null at
9533 the end that can be overwritten, and this way there's no need to
9534 worry about size-calculation overflow.

9664 (X_LONG_MIN): New macros.
9665 Use them to make the following changes clearer.
9666 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

9669 (SELECTION_QUANTUM): Remove, replacing with ...
9670 (selection_quantum): ... new function, which avoids overflow.
9672 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

9694 XGetWindowProperty overflow. Be more careful about overflow
9695 calculations, and distinguish size from memory overflow better.

9739 * lisp.h (hash_lookup, hash_put):
9740 * minibuf.c (Ftest_completion):
9741 Use ptrdiff_t for hash table indexes, not int (which is too

9781 (make_lispy_movement): Use same integer type in forward decl
9782 that is used in the definition.
9783 (read_key_sequence, keyremap_step):
9784 Change bufsize argument back to int, undoing my 2011-03-30 change.

9789 length, not size_t. Use ptrdiff_t for index, not int.

9819 Prefer int to unsigned where either will do.
9820 (tiff_handler): New function, combining the cores of the
9821 old tiff_error_handler and tiff_warning_handler.
9822 This function is rewritten to use vsnprintf and thereby avoid

9873 positioning on the newline at EOL of R2L text within L2R
9874 paragraph, and vice versa.
9875 (try_cursor_movement): Check continued rows, in addition to
9876 continuation rows. Fixes unwarranted scroll when point enters a
9877 continued line of R2L text within an L2R paragraph, or vice versa.
9878 (cursor_row_p): Consider the case of point being equal to
9879 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

9908 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
9909 instead of CHAR_TO_BYTE. Fixes a crash when a completion
9910 candidate is selected by the mouse, and that candidate has a
9911 composed character under the mouse.
9913 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
9914 coordinates reported by pos-visible-in-window-p for a composed

9925 composed buffer positions.
9927 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
9929 * image.c (gif_load): Don't assume that each subimage has the same
9930 dimensions as the base image. Handle disposal method that is
9931 "undefined" by the gif spec (Bug#9335).
9933 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9935 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

9940 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9941 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9942 from an Org mode buffer to a Speedbar frame.
9944 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9945 a composition, take its buffer position from IT->cmp_it.charpos.
9946 Fixes cursor positioning at the beginning of a line that begins
9947 with a composed character.
9949 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9951 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9952 character bidirectional type, use STRONG_L instead. Fixes crashes
9953 in a buffer produced by `describe-categories'.
9955 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9956 members before the level stack, so they would be saved and
9957 restored when copying iterator state. Fixes incorrect reordering
9958 around TABs covered by display properties.
9960 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
9962 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
9964 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
9966 * eval.c (internal_condition_case, internal_condition_case_1)
9967 (internal_condition_case_2, internal_condition_case_n):
9968 Remove unnecessary aborts (Bug#9081).
9970 2011-08-17 Eli Zaretskii <eliz@gnu.org>
9972 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
9973 has no `load' handler, try opening the file locally. (Bug#9311)
9975 2011-08-16 Ken Brown <kbrown@cornell.edu>
9977 * gmalloc.c: Expand comment.
9979 2011-08-16 Eli Zaretskii <eliz@gnu.org>
9981 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
9982 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
9984 2011-08-16 Ken Brown <kbrown@cornell.edu>
9986 Fix memory allocation problems in Cygwin build (Bug#9273).
9988 * unexcw.c ( __malloc_initialized): Declare external variable.
9989 (fixup_executable): Force the dumped emacs to reinitialize malloc.
9991 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
9993 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
9995 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
9997 [CYGWIN] (special_realloc): New function.
9998 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
9999 requests to realloc storage in the static heap.
10001 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
10003 * bidi.c (bidi_initialize): Remove unused local.
10005 2011-08-15 Eli Zaretskii <eliz@gnu.org>
10008 * biditype.h: Remove file.

10010 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
10012 * dispextern.h: Fix a typo in the comment to bidi_type_t.
10014 * chartab.c: Improve commentary for the uniprop_table API.
10016 * bidi.c (bidi_paragraph_init): Support zero value of
10017 bidi_ignore_explicit_marks_for_paragraph_level.
10018 (bidi_initialize): Use uniprop_table instead of including
10019 biditype.h and bidimirror.h.
10021 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10022 coordinates of the iterator when restoring from ppos_it.
10025 2011-08-14 Kenichi Handa <handa@m17n.org>
10027 * process.c (create_process): Call setup_process_coding_systems
10028 after the pid of the process is set to -1 (Bug#8162).
10030 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10032 * xdisp.c (move_it_in_display_line_to): Don't invoke
10033 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10034 ppos_it. Fixes vertical cursor motion when line beginning is
10035 covered by an image. (Bug#9296)
10037 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10039 * nsterm.h (ns_run_ascript): Declare.
10040 (NSAPP_DATA2_RUNASSCRIPT): Define.
10042 * nsfns.m (as_script, as_result, as_status): New static variables.
10043 (ns_run_ascript): New function.
10044 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10045 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10046 the event loop. Get status from as_status (Bug#7276).
10048 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10049 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10050 the event loop (Bug#7276).
10052 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10054 * gnutls.c (QCgnutls_bootprop_priority)
10055 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10056 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10057 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10058 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10059 (QCgnutls_bootprop_verify_hostname_error)
10060 (QCgnutls_bootprop_callbacks_verify): Rename from
10061 Qgnutls_bootprop_..., all uses changed.
10063 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10066 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10068 * xfaces.c (Qframe_set_background_mode): Now static.
10069 * dispextern.h (Qframe_set_background_mode): Remove decl.
10071 * process.c (Fnetwork_interface_info): Declare local only if needed.
10073 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10075 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10076 (Fnetwork_interface_list): Allocate in increments of bytes instead
10077 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10078 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10080 (struct ifflag_def): notrailers is smart on OSX.
10081 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10082 Get hardware address with getifaddrs if available.
10084 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10086 * xdisp.c (iterate_out_of_display_property): xassert that
10087 IT->position is set to within IT->object's boundaries. Break from
10088 the loop as soon as EOB is reached; avoids infloops in redisplay
10089 when IT->position is set up wrongly due to some bug.
10090 Set IT->current to match the bidi iterator unconditionally.
10091 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10092 entry. Force push_it to save on the stack the current
10093 buffer/string position, to be restored by pop_it. Fix flags in
10094 the iterator structure wrt the object coming from a display
10095 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10096 properties. (Bug#9284)
10098 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10100 * fontset.c (fontset_get_font_group): Add proper type checks.
10103 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10105 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
10106 and LC_VERSION_MIN_MACOSX.
10107 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
10108 (dump_it) [LC_FUNCTION_STARTS]: Use it.
10110 2011-08-08 Eli Zaretskii <eliz@gnu.org>
10112 * xdisp.c (forward_to_next_line_start): Allow to use the
10113 no-display-properties-and-no-overlays under bidi display.
10114 Set disp_pos in the bidi iterator to avoid searches for display
10115 properties and overlays.
10117 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10119 * editfns.c (Fset_time_zone_rule): Document relationship with the
10122 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
10123 the font entity extracted from the cache (Bug#8109).
10125 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10127 * composite.c (autocmp_chars): Don't reset point. That is done by
10128 restore_point_unwind (Bug#5984).
10130 2011-08-07 Juri Linkov <juri@jurta.org>
10132 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10133 to show the arg `TIME' instead of `TIMEVAL'.
10135 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10137 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10138 display property strides EOL and includes a newline, as in
10139 longlines-mode. (Bug#9254)
10140 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10141 word-wrap under bidirectional display. (Bug#9224)
10143 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10144 is non-zero, even if the data buffer is NULL. Fixes a crash in
10145 vertical-motion with longlines-mode. (Bug#9254)
10147 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10149 * bidi.c <bidi_cache_total_alloc>: Now static.
10150 (bidi_initialize): Initialize bidi_cache_total_alloc.
10152 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10155 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10156 amount allocated this far in `bidi_cache_total_alloc'.
10157 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10158 non-zero, only free the data buffer without restoring the cache
10159 contents. All callers changed.
10161 * dispextern.h (bidi_unshelve_cache): Update prototype.
10163 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10164 (move_it_in_display_line, move_it_to)
10165 (move_it_vertically_backward, move_it_by_lines): Replace the call
10166 to xfree to an equivalent call to bidi_unshelve_cache.
10167 (move_it_in_display_line_to): Fix logic of returning
10168 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10170 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10172 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10173 came from a string character with a `cursor' property. (Bug#9229)
10175 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10177 * Makefile.in (LIB_PTHREAD): New variable.
10178 (LIBES): Add LIB_PTHREAD (Bug#9216).
10180 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
10181 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
10183 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
10185 * regex.c (re_iswctype): Remove some redundant boolean conversions.
10187 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10189 * xterm.c (x_find_topmost_parent): New function.
10190 (x_set_frame_alpha): Find topmost parent window with
10191 x_find_topmost_parent and set the property there also (bug#9181).
10192 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10194 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10196 * callproc.c (Fcall_process): Avoid vfork clobbering
10197 the local vars buffer, coding_systems, current_dir.
10199 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
10201 * keymap.c (Fmake_composed_keymap): Move to subr.el.
10203 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
10205 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
10206 so that it is not optimized away.
10208 * xdisp.c (compute_display_string_pos): Remove unused local.
10210 2011-08-02 Eli Zaretskii <eliz@gnu.org>
10212 Fix slow cursor motion and scrolling in large buffers with
10213 selective display, like Org Mode buffers. (Bug#9218)
10215 * dispextern.h (struct bidi_it): New member disp_prop_p.
10217 * xdisp.c: Remove one-slot cache of display string positions.
10218 (compute_display_string_pos): Accept an additional argument
10219 DISP_PROP_P; callers changed. Scan at most 5K characters forward
10220 for a display string or property. If found, set DISP_PROP_P
10223 * bidi.c (bidi_fetch_char): Accept an additional argument
10224 DISP_PROP_P, and pass it to compute_display_string_pos.
10225 Only handle text covered by a display string if DISP_PROP_P is returned
10226 non-zero. All callers of bidi_fetch_char changed.
10228 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
10230 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
10232 2010-12-03 Don March <don@ohspite.net>
10234 * keymap.c (Fdefine_key): Fix non-prefix key error message when
10235 last character M-[char] is translated to ESC [char] (bug#7541).
10237 2011-08-02 Kenichi Handa <handa@m17n.org>
10239 * lisp.h (uniprop_table): Extern it.
10241 * chartab.c (uniprop_table): Make it non-static.
10243 2011-08-01 Eli Zaretskii <eliz@gnu.org>
10245 * xdisp.c (forward_to_next_line_start): Accept additional argument
10246 BIDI_IT_PREV, and store into it the state of the bidi iterator had
10248 (reseat_at_next_visible_line_start): Use the bidi iterator state
10249 returned by forward_to_next_line_start to restore the state of
10250 it->bidi_it after backing up to previous newline. (Bug#9212)
10252 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
10254 * regex.c (re_comp): Protoize.
10255 (re_exec): Fix return type.
10256 (regexec): Fix type of `ret'. (Bug#9203)
10258 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10260 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10261 This is needed if max-image-size is a floating-point number.
10263 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10265 * print.c (print_object): Print empty symbol as ##.
10267 * lread.c (read1): Read ## as empty symbol.
10269 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10271 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
10272 setting frame foreground color (Bug#9175).
10273 (x_set_background_color): Likewise.
10275 * nsmenu.m (-setText): Size tooltip dimensions precisely to
10276 contents (Bug#9176).
10277 (EmacsTooltip -init): Remove bezels and add shadows to
10280 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
10281 or scroll bar (Bug#8470).
10283 * nsfont.m (nsfont_open): Remove assignment to voffset and
10284 unnecessary vars hshink, expand, hd, full_height, min_height.
10285 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
10287 * nsterm.h (nsfont_info): Remove voffset field.
10289 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10291 Implement strike-through and overline on NextStep (Bug#8863).
10293 * nsfont.m (nsfont_open): Use underline position provided by font,
10294 instead of hard-coded value of 2.
10295 (nsfont_draw): Call ns_draw_text_decoration instead.
10297 * nsterm.h: Add declaration for ns_draw_text_decoration.
10299 * nsterm.m (ns_draw_text_decoration): New function for drawing
10300 underline, overline, and strike-through.
10301 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
10302 ns_draw_text_decoration. Change treatment of cursor drawing to
10303 accommodate underlining, etc.
10305 2011-07-28 Eli Zaretskii <eliz@gnu.org>
10307 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
10310 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10312 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10313 Without this fix, if a signal arrives just after memory fills up,
10314 'malloc' might be invoked reentrantly.
10316 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10317 In other words, assume that every image size is allowed, on non-X
10318 hosts. This assumption is probably wrong, but it lets Emacs compile.
10320 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10322 * regex.c (re_iswctype): Convert return values to boolean.
10324 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
10326 * xdisp.c (compute_display_string_pos): Don't use cached display
10327 string position if the buffer had its restriction changed.
10330 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10332 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10334 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10336 Integer signedness and overflow and related fixes. (Bug#9079)
10338 * bidi.c: Integer size and overflow fixes.
10339 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
10340 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10341 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10342 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10343 (bidi_find_other_level_edge):
10344 Use ptrdiff_t instead of EMACS_INT where either will do.
10345 This works better on 32-bit hosts configured --with-wide-int.
10346 (bidi_cache_ensure_space): Check for size-calculation overflow.
10347 Use % rather than repeated addition, for better worst-case speed.
10348 Don't set bidi_cache_size until after xrealloc returns, because it
10350 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10351 (bidi_cache_ensure_space): Also check that the bidi cache size
10352 does not exceed that of the largest Lisp string or buffer. See Eli
10353 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10355 * alloc.c (__malloc_size_t): Remove.
10356 All uses replaced by size_t. See Andreas Schwab's note
10357 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10359 * image.c: Improve checking for integer overflow.
10360 (check_image_size): Assume that f is nonnull, since
10361 it is always nonnull in practice. This is one less thing to
10362 worry about when checking for integer overflow later.
10363 (x_check_image_size): New function, which checks for integer
10364 overflow issues inside X.
10365 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10366 This removes the need for a memory_full check.
10367 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10368 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10369 (xbm_read_bitmap_data): Change locals back to 'int', since
10370 their values must fit in 'int'.
10371 (xpm_load_image, png_load, tiff_load):
10372 Invoke x_create_x_image_and_pixmap earlier,
10373 to avoid much needless work if the image is too large.
10374 (tiff_load): Treat overly large images as if
10375 x_create_x_image_and_pixmap failed, not as malloc failures.
10376 (gs_load): Use x_check_image_size.
10378 * gtkutil.c: Omit integer casts.
10379 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10380 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10382 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10384 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10385 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10386 would wrongly return t on a 64-bit host.
10388 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
10389 The plain *_OVERFLOW macros run afoul of GCC bug 49705
10390 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
10391 and therefore cause GCC to emit a bogus diagnostic in some cases.
10393 * image.c: Integer signedness and overflow and related fixes.
10394 This is not an exhaustive set of fixes, but it's time to
10395 record what I've got.
10396 (lookup_pixel_color, check_image_size): Remove redundant decls.
10397 (check_image_size): Don't assume that arbitrary EMACS_INT values
10398 fit in 'int', or that arbitrary 'double' values fit in 'int'.
10399 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
10400 (tiff_load, imagemagick_load_image):
10401 Check for overflow in size calculations.
10402 (x_create_x_image_and_pixmap): Remove unnecessary test for
10403 xmalloc returning NULL; that can't happen.
10404 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
10405 (xpm_color_bucket): Use better integer hashing function.
10406 (xpm_cache_color): Don't possibly over-allocate memory.
10407 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
10408 (gif_memory_source):
10409 Use ptrdiff_t, not int or size_t, to record sizes.
10410 (png_load): Don't assume values greater than 2**31 fit in 'int'.
10411 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
10412 either works, as we prefer signed integers.
10413 (tiff_read_from_memory, tiff_write_from_memory):
10414 Return tsize_t, not size_t, since that's what the TIFF API wants.
10415 (tiff_read_from_memory): Don't fail simply because the read would
10416 go past EOF; instead, return a short read.
10417 (tiff_load): Omit no-longer-needed casts.
10418 (Fimagemagick_types): Don't assume size fits into 'int'.
10420 Improve hashing quality when configured --with-wide-int.
10421 * fns.c (hash_string): New function, taken from sxhash_string.
10422 Do not discard information about ASCII character case; this
10423 discarding is no longer needed.
10424 (sxhash-string): Use it. Change sig to match it. Caller changed.
10425 * lisp.h: Declare it.
10426 * lread.c (hash_string): Remove, since we now use fns.c's version.
10427 The fns.c version returns a wider integer if --with-wide-int is
10428 specified, so this should help the quality of the hashing a bit.
10430 * emacs.c: Integer overflow minor fix.
10431 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
10432 Define only if GNU_LINUX.
10433 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
10435 * dispnew.c: Integer signedness and overflow fixes.
10436 Remove unnecessary forward decls, that were a maintenance hassle.
10437 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
10439 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
10440 (scrolling_window): Use ptrdiff_t, not int, for byte count.
10441 (prepare_desired_row, line_draw_cost):
10442 Use int, not unsigned, where either works.
10443 (save_current_matrix, restore_current_matrix):
10444 Use ptrdiff_t, not size_t, where either works.
10445 (init_display): Check for overflow more accurately, and without
10446 relying on undefined behavior.
10448 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
10449 Remove, replacing with the new symbols in lisp.h. All uses changed.
10450 * fileio.c (make_temp_name):
10451 * filelock.c (lock_file_1, lock_file):
10452 * xdisp.c (message_dolog):
10453 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
10454 Use pMd etc. instead.
10455 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
10456 replacing the pWIDE etc. symbols removed from editfns.c.
10458 * keyboard.h (num_input_events): Now uintmax_t.
10459 This is (very slightly) less likely to mess up due to wraparound.
10462 * buffer.c: Integer signedness fixes.
10463 (alloc_buffer_text, enlarge_buffer_text):
10464 Use ptrdiff_t rather than size_t when either will do, as we prefer
10467 * alloc.c: Integer signedness and overflow fixes.
10468 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
10469 (__malloc_size_t): Default to size_t, not to int.
10470 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
10471 (Fgarbage_collect, mark_object_loop_halt, mark_object):
10472 Prefer ptrdiff_t to size_t when either would do, as we prefer
10474 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
10475 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
10476 Now const. Initialize with values that are in range even if char
10478 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10479 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10480 These functions do the right thing with sizes > 2**32.
10481 (check_depth): Now ptrdiff_t, not int.
10482 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10483 Adjust to new way of storing sizes. Check for size overflow bugs
10485 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10486 slightly wrong anyway, as it missed one instance of
10487 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10488 (refill_memory_reserve): Omit needless cast to size_t.
10489 (mark_object_loop_halt): Mark as externally visible.
10491 * xselect.c: Integer signedness and overflow fixes.
10492 (Fx_register_dnd_atom, x_handle_dnd_message):
10493 Use ptrdiff_t, not size_t, since we prefer signed.
10494 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10495 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10496 x_dnd_atoms_size and x_dnd_atoms_length.
10498 * doprnt.c: Prefer signed to unsigned when either works.
10500 * doprnt.c (doprnt):
10502 * xdisp.c (vmessage):
10503 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10504 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10505 prefer signed arithmetic to avoid comparison confusion.
10506 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10507 but is a bit tricky.
10509 Assume freestanding C89 headers, string.h, stdlib.h.
10510 * data.c, doprnt.c, floatfns.c, print.c:
10511 Include float.h unconditionally.
10512 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10513 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10514 * regex.c: Likewise for stddef.h, string.h.
10515 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10516 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10517 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10518 (STDC_HEADERS): Remove obsolete defines.
10519 * sysdep.c: Include limits.h unconditionally.
10521 Assume support for memcmp, memcpy, memmove, memset.
10522 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10523 * regex.c (memcmp, memcpy):
10524 Remove; we assume C89 now.
10526 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10527 (__malloc_safe_bcopy): Remove; no longer needed.
10529 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10530 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10531 well either way, and we prefer signed to unsigned.
10533 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10535 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10536 closes the connection while we're reading (bug#9182).
10538 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10540 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10541 are specified (Bug#9168).
10543 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10545 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10546 Found by GCC static checking and --with-wide-int on a 32-bit host.
10548 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10550 * xdisp.c (compute_display_string_pos): Fix logic of caching
10551 previous display string position. Initialize cached_prev_pos to
10552 -1. Fixes slow-down at the beginning of a buffer.
10554 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10556 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10557 for attrs[LFACE_FONTSET_INDEX].
10559 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10561 * xml.c (parse_region): Remove unused local
10562 that was recently introduced.
10564 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10566 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10567 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10569 * xdisp.c (move_it_in_display_line_to): Record the best matching
10570 position for TO_CHARPOS while scanning the line, and restore it on
10571 exit if none of the characters scanned was an exact match.
10572 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
10573 when exact match is impossible due to invisible text, and the
10574 lines are truncated.
10576 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
10578 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
10581 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10583 Fix a significant slow-down of cursor motion with C-n, C-p,
10584 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
10585 auto-repeat under bidi redisplay in fontified buffers.
10586 * xdisp.c (compute_stop_pos_backwards): New function.
10587 (next_element_from_buffer): Call compute_stop_pos_backwards to
10588 find a suitable prev_stop when we find ourselves before
10590 (reseat): Don't look for prev_stop, as that could mean a very long
10592 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
10593 <cached_disp_overlay_modiff>: Cache for last found display string
10595 (compute_display_string_pos): Return the cached position if asked
10596 about the same buffer in the same area of character positions, and
10597 the buffer wasn't changed since the time the display string
10598 position was cached.
10600 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10602 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
10603 is an integer, which is important for empty lines. (Bug#9149)
10605 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
10607 * frame.c (Fmodify_frame_parameters): In tty case, update the
10608 default face if necessary (Bug#4238).
10610 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
10612 * editfns.c (Fstring_to_char): No need to explain what a character
10613 is in the docstring (Bug#6576).
10615 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10617 * xml.c (parse_region): Make sure we always return a tree.
10619 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
10621 * xml.c (parse_region): If a document contains only comments,
10624 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10626 * xml.c (make_dom): Return comments, too.
10628 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
10631 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
10632 and the surrounding thread.
10633 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
10634 rather than fgets, and retry after EINTR. Otherwise, 'emacs
10635 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
10637 * s/openbsd.h (BROKEN_SIGIO): Define.
10638 * unexelf.c (unexec) [__OpenBSD__]:
10639 Don't update the .mdebug section of the Alpha COFF symbol table.
10641 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10643 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
10646 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
10648 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
10649 This fixes some race conditions on the permissions of any newly
10652 * alloc.c (valid_pointer_p): Use pipe, not open.
10653 This fixes some permissions issues when debugging.
10655 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
10656 If fchown fails to set both uid and gid, try to set just gid,
10657 as that is sometimes allowed. Adjust the file's mode to eliminate
10658 setuid or setgid bits that are inappropriate if fchown fails.
10660 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
10662 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
10663 to compare Lisp_Objects.
10664 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
10665 global_gnutls_log_level, don't mistake it for a Lisp_Object.
10666 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
10668 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
10670 * lread.c (read_integer): Unread even EOF character.
10671 (read1): Likewise. Properly record start position of symbol.
10673 * lread.c (read1): Read `#:' as empty uninterned symbol if no
10674 symbol character follows.
10676 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
10678 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
10679 This works around a problem with the previous change to Fcopy_file.
10680 Recent glibc declares fchown with __attribute__((warn_unused_result)),
10681 and without this change, GCC might complain about discarding
10682 fchown's return value.
10684 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
10686 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
10688 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
10690 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
10692 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
10694 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
10695 it's used from the C level.
10697 * process.c: Use the same condition for POLL_FOR_INPUT in both
10698 keyboard.c and process.c (bug#1858).
10700 2011-07-09 Lawrence Mitchell <wence@gmx.li>
10702 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
10703 (Fgnutls_boot): Use it.
10705 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
10707 * doc.c (Fsubstitute_command_keys): Revert last change.
10709 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
10711 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
10712 quotes the next character, and doesn't affect other longer
10713 sequences (bug#8935).
10715 * lread.c (syms_of_lread): Clarify that is isn't only
10716 `eval-buffer' and `eval-defun' that's affected by
10717 `lexical-binding' (bug#8460).
10719 2011-07-15 Eli Zaretskii <eliz@gnu.org>
10721 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
10722 bidi redisplay when a line includes both an image and is truncated.
10724 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
10726 Fix minor problems found by static checking.
10727 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
10728 (elsz): Now a signed constant, not a size_t var. We prefer signed
10729 types to unsigned, to avoid integer comparison confusion. Without
10730 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
10731 "cannot optimize loop, the loop counter may overflow", a symptom
10733 * indent.c (Fvertical_motion): Mark locals as initialized.
10734 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
10736 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
10738 * search.c (Fre_search_backward): Mention `case-fold-search' in
10739 all the re_search_* functions (bug#8138).
10741 * keyboard.c (Fopen_dribble_file): Document when the file is

10752 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
10753 (reseat_to_string): Initialize bidi_it->string.s and
10754 bidi_it->string.schars.
10755 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
10756 NULL (avoids a crash in bidi_paragraph_init).
10757 Initialize itb.string.lstring.
10758 (init_iterator): Call bidi_init_it only of a valid
10759 buffer position was specified. Initialize paragraph_embedding to
10761 (reseat_to_string): Initialize the bidi iterator.
10762 (display_string): If we need to ignore text properties of
10763 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
10764 original value of -1 will not work with bidi.)
10765 (compute_display_string_pos): First arg is now struct
10766 `text_pos *'; all callers changed. Support display properties on
10768 (compute_display_string_end): Support display properties on Lisp
10770 (init_iterator, reseat_1, reseat_to_string): Initialize the
10771 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
10772 when iterating on a string not from display properties).
10773 (compute_display_string_pos, compute_display_string_end):
10774 Fix calculation of the object to scan. Fixes an error when using
10776 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
10777 base_level_stop; instead, set base_level_stop to BEGV.
10778 Fixes crashes in vertical-motion.
10779 (next_element_from_buffer): Improve commentary for when
10780 the iterator is before prev_stop.
10781 (init_iterator): Initialize bidi_p from the default value of
10782 bidi-display-reordering, not from buffer-local value. Use the
10783 buffer-local value only if initializing for buffer iteration.
10784 (handle_invisible_prop): Support invisible properties on strings
10785 that are being bidi-reordered.
10786 (set_iterator_to_next): Support bidi reordering of C strings and
10788 (next_element_from_string): Support bidi reordering of Lisp
10790 (handle_stop_backwards): Support Lisp strings as well.
10791 (display_string): Support display of R2L glyph rows.
10792 Use IT_STRING_CHARPOS when displaying from a Lisp string.
10793 (init_iterator): Don't initialize it->bidi_p for strings
10795 (reseat_to_string): Initialize it->bidi_p for strings here.
10796 (next_element_from_string, next_element_from_c_string)
10797 (next_element_from_buffer): Add xassert's for correspondence
10798 between IT's object being iterated and it->bidi_it.string
10800 (face_before_or_after_it_pos): Support bidi iteration.
10801 (next_element_from_c_string): Handle the case of the first string
10802 character that is not the first one in the visual order.
10803 (get_visually_first_element): New function, refactored from common
10804 parts of next_element_from_buffer, next_element_from_string, and
10805 next_element_from_c_string.
10806 (tool_bar_lines_needed, redisplay_tool_bar)
10807 (display_menu_bar): Force left-to-right direction. Add a FIXME
10808 comment for making that be controlled by a user option.
10809 (push_it, pop_it): Save and restore the state of the
10810 bidi iterator. Save and restore the bidi_p flag.
10811 (pop_it): Iterate out of display property for string iteration as
10813 (iterate_out_of_display_property): Support iteration over strings.
10814 (handle_single_display_spec): Set up it->bidi_it for iteration
10815 over a display string, and call bidi_init_it.
10816 (handle_single_display_spec, next_overlay_string)
10817 (get_overlay_strings_1, push_display_prop): Set up the bidi
10818 iterator for displaying display or overlay strings.
10819 (forward_to_next_line_start): Don't use the shortcut if
10821 (back_to_previous_visible_line_start): If handle_display_prop
10822 pushed the iterator stack, restore the internal state of the bidi
10823 iterator by calling bidi_pop_it same number of times.
10824 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
10825 and we are bidi-iterating, don't decrement the iterator position;
10826 instead, set the first_elt flag in the bidi iterator, to produce
10828 (reseat_1): Remove redundant setting of string_from_display_prop_p.
10829 (push_display_prop): xassert that we are iterating a buffer.
10830 (push_it, pop_it): Save and restore paragraph_embedding member.
10831 (handle_single_display_spec, next_overlay_string)
10832 (get_overlay_strings_1, reseat_1, reseat_to_string)
10833 (push_display_prop): Set up the `unibyte' member of bidi_it.string
10834 correctly. Don't assume unibyte strings are not bidi-reordered.
10835 (compute_display_string_pos)
10836 (compute_display_string_end): Fix handling the case of C string.
10837 (push_it, pop_it): Save and restore from_disp_prop_p.
10838 (handle_single_display_spec, push_display_prop): Set the
10839 from_disp_prop_p flag.
10840 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
10841 (pop_it): Call iterate_out_of_display_property only if we are
10842 popping after iteration over a string that came from a display
10843 property. Fix a typo in popping stretch info. Add an assertion
10844 for verifying that the iterator position is in sync with the bidi
10846 (handle_single_display_spec, get_overlay_strings_1)
10847 (push_display_prop): Fix initialization of paragraph direction for
10848 string when that of the parent object is not yet determined.
10849 (reseat_1): Call bidi_init_it to resync the bidi
10850 iterator with IT's position. (Bug#7616)
10851 (find_row_edges): If ROW->start.pos gives position
10852 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
10853 (handle_stop, back_to_previous_visible_line_start, reseat_1):

11297 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
11299 Random fixes. E.g., (random) never returned negative values.
11300 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11301 subseconds part to the entropy, as that's a bit more random.
11302 Prefer signed to unsigned, since the signedness doesn't matter and
11303 in general we prefer signed. When given a limit, use a
11304 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11305 latter isn't right if USE_2_TAGS_FOR_INTS.
11306 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11307 not 0..VALMASK. Don't discard "excess" bits that random () returns.
11309 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11311 * textprop.c (text_property_stickiness):
11312 Obey Vtext_property_default_nonsticky.

11319 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
11320 This is more efficient than Ffile_directory_p and avoids a minor race.
11322 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
11324 * buffer.c (Foverlay_put): Say what the return value is
11327 * fileio.c (barf_or_query_if_file_exists): Check first if the file
11328 is a directory before asking whether to use the file name
11330 (barf_or_query_if_file_exists): Make the "File is a directory"
11331 error be more correct.
11333 * fns.c (Frequire): Remove the mention of the .gz files, since
11334 that's installation-specific, but keep the mention of
11335 `get-load-suffixes'.
11337 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
11339 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

11342 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
11344 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
11345 (syms_of_gnutls): Remove duplicate DEFSYM for
11346 Qgnutls_bootprop_verify_hostname_error, an error for
11347 Qgnutls_bootprop_verify_error (which is no longer used).
11349 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
11350 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11351 Also (re)move comments that are misplaced or no longer relevant.
11353 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11355 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

11380 * lread.c (syms_of_lread): Mention single symbols defined by
11381 `defvar' or `defconst' (bug#7154).
11383 * fns.c (Frequire): Mention .el.gz files (bug#7314).
11384 (Frequire): Mention get-load-suffixes.
11386 2011-07-02 Martin Rudalics <rudalics@gmx.at>

11452 * eval.c (struct backtrace): Simplify and port the data structure.
11453 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
11454 signed bit field, as this assumption is not portable and it makes
11455 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
11456 "char debug_on_exit : 1" as this is not portable either; instead,
11457 use the portable "unsigned int debug_on_exit : 1". Remove unused
11458 member evalargs. Remove obsolete comments about cc bombing out.
11460 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

11530 (emacs_fixed_get_preferred_height): Use min_width/height from
11531 frames size_hint to set minimum and natural (Bug#8919).
11532 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
11533 and use min_width/height from frames size_hint to set
11534 min_width/height (Bug#8919).

11554 Use gnulib's dup2 module instead of rolling our own.
11555 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

11627 (PRINTPREPARE, printchar, strout):
11628 Don't set size unless allocation succeeds.
11630 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
11631 for sizes. Check for string overflow more accurately.

11645 (read_integer): Radix is now EMACS_INT, not int,
11646 to improve quality of diagnostics for out-of-range radices.
11647 Calculate buffer size correctly for out-of-range radices.
11648 (read1): Check for integer overflow in radices, and in
11649 read-circle numbers.
11650 (read_escape): Avoid int overflow.
11651 (Fload, openp, read_buffer_size, read1)
11652 (substitute_object_recurse, read_vector, read_list, map_obarray):
11653 Use ptrdiff_t, not int, for sizes.

11675 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
11676 The following patches are for when GLYPH_DEBUG && !XASSERT.
11677 * dispextern.h (trace_redisplay_p, dump_glyph_string):
11678 * dispnew.c (flush_stdout):
11679 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
11680 Mark as externally visible.
11681 * dispnew.c (check_window_matrix_pointers): Now static.
11682 * dispnew.c (window_to_frame_vpos):
11683 * xfns.c (unwind_create_frame):

11690 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
11692 (debug_method_add): Use va_list and vsprintf rather than relying
11693 on undefined behavior with wrong number of arguments.
11694 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
11695 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
11696 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
11697 since we're not interested in debugging glyphs with old libraries.
11698 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
11699 GCC 4.6.0's static checking.
11701 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

11731 * buffer.c (OVERLAY_COUNT_MAX): New macro.
11732 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
11733 (Fnext_overlay_change, Fprevious_overlay_change)
11734 (mouse_face_overlay_overlaps, Foverlays_in):
11735 Use ptrdiff_t, not int, for sizes.
11736 (overlays_at, overlays_in): Check for size-calculation overflow.
11738 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
11740 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
11741 (x_session_initialize): Do not assume string length fits in int.
11743 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
11744 This is unlikely, but can occur if DPI is outlandish.
11746 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
11747 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
11749 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
11750 * xrdb.c (magic_file_p, search_magic_path):
11751 Omit last arg SUFFIX; it was always 0. All callers changed.
11752 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
11754 * xfont.c (xfont_match): Avoid need for strlen.
11756 * xfns.c: Don't assume strlen fits in int.
11757 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
11759 * xdisp.c (message_log_check_duplicate): Return intmax_t,
11760 not unsigned long, as we prefer signed integers. All callers changed.
11761 Detect integer overflow in repeat count.
11762 (message_dolog): Don't assume print length fits in 39 bytes.
11763 (display_mode_element): Don't assume strlen fits in int.
11765 * termcap.c: Don't assume sizes fit in int and never overflow.
11766 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
11767 (gobble_line): Check for size-calculation overflow.
11769 * minibuf.c (Fread_buffer):
11770 * lread.c (intern, intern_c_string):
11771 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
11772 Don't assume string length fits in int.
11774 * keyboard.c (parse_tool_bar_item):
11775 * gtkutil.c (style_changed_cb): Avoid need for strlen.
11777 * font.c: Don't assume string length fits in int.
11778 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
11779 Use ptrdiff_t, not int.
11780 (font_intern_prop): Don't assume string length fits in int.
11781 Don't assume integer property fits in fixnum.
11782 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
11784 * filelock.c: Fix some buffer overrun and integer overflow issues.
11785 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
11786 Reformulate so as not to need the command string.
11787 Invoke gzip -cd rather than gunzip, as it's more portable.
11788 (lock_info_type, lock_file_1, lock_file):
11789 Don't assume pid_t and time_t fit in unsigned long.
11790 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
11791 (current_lock_owner): Prefer signed type for sizes.
11792 Use memcpy, not strncpy, where memcpy is what is really wanted.
11793 Don't assume (via atoi) that time_t and pid_t fit in int.
11794 Check for time_t and/or pid_t out of range, e.g., via a network share.
11795 Don't alloca where an auto var works fine.
11797 * fileio.c: Fix some integer overflow issues.
11798 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
11799 Don't assume string length fits in int.
11800 (directory_file_name): Don't assume string length fits in long.
11801 (make_temp_name): Don't assume pid fits in int, or that its print
11802 length is less than 20.
11804 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
11806 * coding.c (make_subsidiaries): Don't assume string length fits in int.
11808 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
11810 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
11811 We prefer signed integers, even for size calculations.
11813 * emacs.c: Don't assume string length fits in 'int'.
11814 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
11815 (main): Don't invoke strlen when not needed.
11817 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
11818 (XD_DEBUG_MESSAGE): Don't waste a byte.
11820 * callproc.c (getenv_internal_1, getenv_internal)
11821 (Fgetenv_internal):
11822 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
11824 * lread.c (invalid_syntax): Omit length argument.
11825 All uses changed. This doesn't fix a bug, but it simplifies the
11826 code away from its former Hollerith-constant appearance, and it's
11827 one less 'int' to worry about when looking at integer-overflow issues.
11828 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
11830 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
11831 This didn't break anything, but it didn't help either.
11832 It's confusing to put a bogus integer in a place where the actual
11833 value does not matter.
11834 (LIST_END_P): Remove unused macro and its bogus comment.
11835 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
11837 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11838 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
11840 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
11841 We prefer signed types, and the value cannot exceed the EMACS_INT
11842 range anyway (because otherwise the length would not be representable).
11843 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
11844 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
11845 This avoids a GCC warning when WIDE_EMACS_INT.
11847 * indent.c (sane_tab_width): New function.
11848 (current_column, scan_for_column, Findent_to, position_indentation)
11849 (compute_motion): Use it. This is just for clarity.
11850 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
11852 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
11854 * lisp.h (lint_assume): New macro.
11855 * composite.c (composition_gstring_put_cache):
11856 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
11858 * editfns.c, insdel.c:
11859 Omit unnecessary forward decls, to simplify future changes.
11861 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
11863 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
11865 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
11866 Use much-faster test for byte-length change.
11867 Don't assume string byte-length fits in 'int'.
11868 Check that character arg fits in 'int'.
11869 (mapcar1): Declare byte as byte, for clarity.
11871 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
11873 * fns.c (concat): Catch string overflow earlier.
11874 Do not rely on integer wraparound.
11876 * dispextern.h (struct it.overlay_strings_charpos)
11877 (struct it.selective): Now EMACS_INT, not int.
11878 * xdisp.c (forward_to_next_line_start)
11879 (back_to_previous_visible_line_start)
11880 (reseat_at_next_visible_line_start, next_element_from_buffer):
11881 Don't arbitrarily truncate the value of 'selective' to int.
11883 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
11885 * composite.c: Don't truncate sizes to 'int'.
11886 (composition_gstring_p, composition_reseat_it)
11887 (composition_adjust_point): Use EMACS_INT, not int.
11888 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
11889 not EMACS_UINT, for indexes.
11891 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
11893 * buffer.c: Include <verify.h>.
11894 (struct sortvec.priority, struct sortstr.priority):
11895 Now EMACS_INT, not int.
11896 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
11897 (struct sortstr.size, record_overlay_string)
11898 (struct sortstrlist.size, struct sortlist.used):
11899 Don't truncate size to int.
11900 (record_overlay_string): Check for size-calculation overflow.
11901 (init_buffer_once): Check at compile-time, not run-time.
11903 2011-06-22 Jim Meyering <meyering@redhat.com>
11905 Don't leak an XBM-image-sized buffer
11906 * image.c (xbm_load): Free the image buffer after using it.
11908 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
11911 * composite.c (find_automatic_composition): Omit needless 'return 0;'
11912 that Sun C diagnosed.
11913 * fns.c (secure_hash): Fix pointer signedness issue.
11914 * intervals.c (static_offset_intervals): New function.
11915 (offset_intervals): Use it.
11917 2011-06-21 Leo Liu <sdl.web@gmail.com>
11920 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
11923 * fns.c (secure_hash): Rename from crypto_hash_function and change
11924 the first arg to accept symbols.
11925 (Fsecure_hash): New primitive.
11926 (syms_of_fns): New symbols.
11928 2011-06-20 Deniz Dogan <deniz@dogan.se>
11930 * process.c (Fset_process_buffer): Clarify return value in
11933 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11935 * dispnew.c (add_window_display_history): Use BVAR.
11937 * xdisp.c (debug_method_add): Use BVAR.
11938 (check_window_end, dump_glyph_matrix, dump_glyph)
11939 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11941 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11944 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11945 check till after the cache is created in init_frame_faces.
11947 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11949 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11951 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11953 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11954 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11955 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11957 Improve buffer-overflow checking (Bug#8873).
11958 * fileio.c (Finsert_file_contents):
11959 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11960 Remove the old (too-loose) buffer overflow checks.
11961 They weren't needed, since make_gap checks for buffer overflow.
11962 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11963 The old code merely checked for Emacs fixnum overflow, and relied
11964 on undefined (wraparound) behavior. The new code avoids undefined
11965 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11967 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11968 Tune. Don't use wider integers than needed. Don't use alloca.
11969 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11971 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11973 * insdel.c, lisp.h (buffer_overflow): New function.
11974 (insert_from_buffer_1, replace_range, replace_range_2):
11975 * insdel.c (make_gap_larger):
11976 * editfns.c (Finsert_char):
11977 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11979 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11981 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11983 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11985 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11986 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11988 * fileio.c: Don't assume EMACS_INT fits in off_t.
11989 (emacs_lseek): New static function.
11990 (Finsert_file_contents, Fwrite_region): Use it.
11991 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11993 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11995 * fns.c: Don't overflow int when computing a list length.
11996 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11997 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11998 truncation on 64-bit hosts. Check for QUIT every
11999 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12000 faster and is responsive enough.
12001 (Flength): Report an error instead of overflowing an integer.
12002 (Fsafe_length): Return a float if the value is not representable
12003 as a fixnum. This shouldn't happen except in contrived situations.
12004 (Fnthcdr, Fsort): Don't assume list length fits in int.
12005 (Fcopy_sequence): Don't assume vector length fits in int.
12007 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12008 (header_size, word_size): New constants.
12009 (allocate_vectorlike): Don't check size overflow here.
12010 (allocate_vector): Check it here instead, since this is the only
12011 caller of allocate_vectorlike that could cause overflow.
12012 Check that the new vector's length is representable as a fixnum.
12014 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12015 The previous code was bogus. For example, next_almost_prime (32)
12016 returned 39, which is undesirable as it is a multiple of 3; and
12017 next_almost_prime (24) returned 25, which is a multiple of 5 so
12018 why was the code bothering to check for multiples of 7?
12020 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12022 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12024 Variadic C functions now count arguments with ptrdiff_t.
12025 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12026 Back then I didn't know that the Emacs coding style prefers signed int.
12027 Also, in the meantime I found a few more instances where arguments
12028 were being counted with int, which may truncate counts on 64-bit
12029 machines, or EMACS_INT, which may be unnecessarily wide.
12030 * lisp.h (struct Lisp_Subr.function.aMANY)
12031 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12032 Arg counts are now ptrdiff_t, not size_t.
12033 All variadic functions and their callers changed accordingly.
12034 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12035 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12036 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12037 * callint.c (Fcall_interactively): Check arg count for overflow,
12038 to avoid potential buffer overrun. Use signed char, not 'int',
12039 for 'varies' array, so that we needn't bother to check its size
12040 calculation for overflow.
12041 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12042 * eval.c (apply_lambda):
12043 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12044 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12045 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12047 * callint.c (Fcall_interactively): Don't use index var as event count.
12049 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12050 * mem-limits.h (SIZE): Remove; no longer used.
12052 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12054 Remove unnecessary casts.
12055 * xterm.c (x_term_init):
12056 * xfns.c (x_set_border_pixel):
12057 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12058 These aren't needed now that we assume ANSI C.
12060 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12061 It's more likely to cause problems (due to unsigned overflow)
12064 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12066 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12068 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12070 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12072 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12074 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12076 GLYPH_CODE_FACE returns EMACS_INT, not int.
12077 * dispextern.h (merge_faces):
12078 * xfaces.c (merge_faces):
12079 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12080 Don't assume EMACS_INT fits in int.
12082 * character.h (CHAR_VALID_P): Remove unused parameter.
12083 * fontset.c, lisp.h, xdisp.c: All uses changed.
12085 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12087 * fns.c (concat): Minor tuning based on overflow analysis.
12088 This doesn't fix any bugs. Use int to hold character, instead
12089 of constantly refetching from Emacs object. Use XFASTINT, not
12090 XINT, for value known to be a character. Don't bother comparing
12091 a single byte to 0400, as it's always less.
12093 * floatfns.c (Fexpt):
12094 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12096 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12099 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12101 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12102 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12103 incorrectly succeed when S was a string, because 4294967386 was
12104 truncated before it was used.
12106 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12107 Otherwise, an out-of-range integer could cause undefined behavior
12110 * composite.c: Use int, not EMACS_INT, for characters.
12111 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12112 EMACS_INT, for values that are known to be in character range.
12113 This doesn't fix any bugs but is the usual style inside Emacs and
12114 may generate better code on 32-bit machines.
12116 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12117 This is for reasons similar to the recent CHAR_STRING fix.
12118 * charset.c (Fencode_char): Check that character arg is actually
12119 a character. Pass an int to ENCODE_CHAR.
12120 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12121 wider than 'int', as a compile-time check to prevent future regressions
12124 * character.c (char_string): Remove unnecessary casts.
12126 Make sure a 64-bit char is never passed to CHAR_STRING.
12127 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12128 by silently ignoring the top 32 bits, allowing some values
12129 that were far too large to be valid characters.
12130 * character.h: Include <verify.h>.
12131 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12132 arguments are no wider than unsigned, as a compile-time check
12133 to prevent future regressions in this area.
12135 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12136 (Fsubst_char_in_region):
12138 * xdisp.c (decode_mode_spec_coding):
12139 Adjust to CHAR_STRING's new requirement.
12140 * editfns.c (Finsert_char, Fsubst_char_in_region):
12141 * fns.c (concat): Check that character args are actually
12142 characters. Without this test, these functions did the wrong
12143 thing with wildly out-of-range values on 64-bit hosts.
12145 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12146 These casts should not be needed on 32-bit hosts, either.
12147 * keyboard.c (read_char):
12148 * lread.c (Fload): Remove casts to unsigned.
12150 * lisp.h (UNSIGNED_CMP): New macro.
12151 This fixes comparison bugs on 64-bit hosts.
12152 (ASCII_CHAR_P): Use it.
12153 * casefiddle.c (casify_object):
12154 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12155 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12156 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12157 * dispextern.h (FACE_FROM_ID):
12158 * keyboard.c (read_char): Use UNSIGNED_CMP.
12160 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12161 not to EMACS_INT, to avoid GCC warning.
12163 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12165 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12166 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12167 isn't needed on 32-bit machines.
12169 * buffer.c (Fgenerate_new_buffer_name):
12170 Use EMACS_INT for count, not int.
12171 (advance_to_char_boundary): Return EMACS_INT, not int.
12173 * data.c (Qcompiled_function): Now static.

12802 instead of using explicit *_CHAR codes.
12803 (bidi_resolve_explicit, bidi_resolve_weak):

12812 (bidi_level_of_next_char): Don't try to lookup the cache for the
12813 next/previous character if nothing is cached there yet, or if we
12814 were just reseat()'ed to a new position.
12816 * xdisp.c (set_cursor_from_row): Set start and stop points
12817 according to the row's direction when priming the loop that looks
12818 for the glyph on which to display cursor.

12820 (display_prop_intangible_p): Reimplement to call
12821 handle_display_spec instead of single_display_spec_intangible_p.
12822 Accept 3 additional arguments needed by handle_display_spec.
12823 This fixes incorrect cursor motion across display property with complex
12824 values: lists, `(when COND...)' forms, etc.

12826 lists with the argument STRING its top-level element.
12827 (display_prop_string_p): Fix the condition for processing a

12831 (compute_display_string_pos): Accept additional argument
12832 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
12833 value of a `display' property is a "replacing spec".
12834 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
12835 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
12836 the display property, but just return a value indicating whether
12837 the display property will replace the characters it covers.
12838 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
12839 frame_window_p members of struct bidi_it.

12865 * gnutls.c: Use Emacs's memory allocators.
12866 Without this change, the gnutls library would invoke malloc etc.
12867 directly, which causes problems on non-SYNC_INPUT hosts, and which
12868 runs afoul of improving memory_full behavior. (Bug#8761)
12869 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
12870 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
12871 xfree instead of the default malloc, realloc, free.
12872 (Fgnutls_boot): No need to check for memory allocation failure,
12873 since xmalloc does that for us.
12875 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

12896 for hashes and hash indexes, instead of 'unsigned' and 'int'.
12897 * alloc.c (allocate_vectorlike):
12898 Check for overflow in vector size calculations.
12899 * ccl.c (ccl_driver):
12900 Check for overflow when converting EMACS_INT to int.

12902 need to be updated by these changes.
12903 * fns.c (make_hash_table, maybe_resize_hash_table):
12904 Check for integer overflow with large hash tables.
12905 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
12906 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
12907 (SXHASH_REDUCE): New macro.
12908 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
12909 Use it instead of discarding useful hash info with large hash values.
12910 (sxhash_float): New function.
12911 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
12912 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
12913 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
12914 Rewrite to use FIXNUM_BITS, as this simplifies things.
12915 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
12916 Adjust signatures to match updated version of code.
12917 (consing_since_gc): Now EMACS_INT, since a single hash table can
12918 use more than INT_MAX bytes.

12967 Make it possible to run ./temacs.
12969 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12970 syms_of_callproc does the same thing. Remove test for

13031 * fns.c (to_uchar): Define.
13032 (crypto_hash_function): Use it to convert some newly-signed

13045 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13046 to hold a serial number that is too large for a fixnum.
13047 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13048 Check for serial numbers out of range. Decode any serial number
13049 that was so large that it became a float. (Bug#8722)
13051 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13052 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13053 Use XFASTINT rather than XUINT when numbers are nonnegative.
13054 (xd_append_arg, Fdbus_method_return_internal):
13055 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13056 arguments, check that Lisp number is nonnegative, rather than
13057 silently wrapping negative numbers around. (Bug#8722)
13058 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13061 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13063 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13065 ccl: Add integer overflow checks.
13066 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13067 (IN_INT_RANGE): New macros.
13068 (ccl_driver): Use them to check for integer overflow when
13069 decoding a CCL program. Many of the new checks are whether XINT (x)
13070 fits in int; it doesn't always, on 64-bit hosts. The new version
13071 doesn't catch all possible integer overflows, but it's an
13072 improvement. (Bug#8719)
13074 * alloc.c (make_event_array): Use XINT, not XUINT.
13075 There's no need for unsigned here.
13077 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13078 This follows up to the 2011-05-06 change that substituted uintptr_t
13079 for EMACS_INT. This case wasn't caught back then.
13081 Rework Fformat to avoid integer overflow issues.
13082 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13083 now (part of C89). Include <verify.h>.
13084 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13085 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13086 (Fformat): Avoid the prepass trying to compute sizes; it was only
13087 approximate and thus did not catch overflow reliably. Instead, walk
13088 through the format just once, formatting and computing sizes as we go,
13089 checking for integer overflow at every step, and allocating a larger
13090 buffer as needed. Keep track separately whether the format is
13091 multibyte. Keep only the most-recently calculated precision, rather
13092 than them all. Record whether each argument has been converted to
13093 string. Use EMACS_INT, not int, for byte and char and arg counts.
13094 Support field widths and precisions larger than INT_MAX. Avoid
13095 sprintf's undefined behavior with conversion specifications such as %#d
13096 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13097 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13098 formatting out-of-range floating point numbers with int
13099 formats. (Bug#8668)
13101 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13103 * data.c: Avoid integer truncation in expressions involving floats.
13104 * data.c: Include <intprops.h>.
13105 (arith_driver): When there's an integer overflow in an expression
13106 involving floating point, convert the integers to floating point
13107 so that the resulting value does not suffer from catastrophic
13108 integer truncation. For example, on a 64-bit host (* 4
13109 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13110 Do not rely on undefined behavior after integer overflow.
13112 merge count_size_as_multibyte, parse_str_to_multibyte
13113 * character.c, character.h (count_size_as_multibyte):
13114 Rename from parse_str_to_multibyte; all uses changed.
13115 Check for integer overflow.
13116 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13117 since it's now a duplicate of the other. This is more of
13118 a character than a buffer op, so better that it's in character.c.
13119 * fns.c, print.c: Adjust to above changes.
13121 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13123 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13125 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13127 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13128 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13129 (x_clipboard_manager_save): Now static.
13130 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13132 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13133 (crypto_hash_function): Now static.
13134 Fix pointer signedness problems. Avoid unnecessary initializations.
13136 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13138 * termhooks.h (Vselection_alist): Make it terminal-local.
13140 * terminal.c (create_terminal): Initialize it.
13142 * xselect.c: Support for clipboard managers.
13143 (Vselection_alist): Move to termhooks.h as terminal-local var.
13144 (LOCAL_SELECTION): New macro.
13145 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13146 (symbol_to_x_atom): Remove gratuitous arg.
13147 (x_handle_selection_request, lisp_data_to_selection_data)
13148 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13149 (x_own_selection, x_get_local_selection, x_convert_selection):
13150 New arg, specifying work frame. Use terminal-local Vselection_alist.
13151 (some_frame_on_display): Delete unused function.
13152 (Fx_own_selection_internal, Fx_get_selection_internal)
13153 (Fx_disown_selection_internal, Fx_selection_owner_p)
13154 (Fx_selection_exists_p): New optional frame arg.
13155 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13156 (x_handle_selection_clear): Don't treat other terminals with the
13157 same keyboard specially. Use the terminal-local Vselection_alist.
13158 (x_clear_frame_selections): Use Frun_hook_with_args.
13160 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13162 * xterm.h: Add support for those atoms.
13164 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13166 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13167 (converted_selections, conversion_fail_tag): New global variables.
13168 (x_selection_request_lisp_error): Free the above.
13169 (x_get_local_selection): Remove unnecessary code.
13170 (x_reply_selection_request): Args changed; handle arbitrary array
13171 of converted selections stored in converted_selections.
13172 Separate the XChangeProperty and SelectionNotify steps.
13173 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13174 (x_convert_selection): New function.
13175 (x_handle_selection_event): Simplify.
13176 (x_get_foreign_selection): Don't ignore incoming requests while
13177 waiting for an answer; this will fail when we implement
13178 SAVE_TARGETS, and seems unnecessary anyway.
13179 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13180 (Vx_sent_selection_functions): Doc fix.
13182 2011-05-26 Leo Liu <sdl.web@gmail.com>
13184 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13186 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13188 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13190 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13191 for fringe update if it has periodic bitmap.
13192 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13193 and fringe_bitmap_periodic_p.
13195 * fringe.c (get_fringe_bitmap_data): New function.
13196 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13197 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13198 row. Mark glyph row for fringe update if periodicity changed.
13200 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13201 for fringe update unless it has periodic bitmap.
13203 2011-05-25 Kenichi Handa <handa@m17n.org>
13205 * xdisp.c (get_next_display_element): Set correct it->face_id for
13206 a static composition.
13208 2011-05-24 Leo Liu <sdl.web@gmail.com>
13211 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
13213 * fns.c (crypto_hash_function, Fsha1): New function.
13214 (Fmd5): Use crypto_hash_function.
13215 (syms_of_fns): Add Ssha1.
13217 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13219 * gnutls.c: Remove unused macros.
13220 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13221 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13222 Remove macros that are defined and never used.
13223 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13225 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13227 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13228 (Fx_get_selection_internal): Minor cleanup.
13229 (Fx_own_selection_internal): Rename arguments for consistency with
13232 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13234 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
13236 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13238 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
13240 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13242 * dispnew.c (scrolling_window): Don't exclude the case that the
13243 last enabled row in the desired matrix touches the bottom boundary.
13245 2011-05-21 Glenn Morris <rgm@gnu.org>
13247 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
13248 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
13249 and add some more files.
13251 2011-05-20 Eli Zaretskii <eliz@gnu.org>
13253 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
13254 report_file_error introduced by the change from 2011-05-07.
13256 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13258 * systime.h (Time): Define only if emacs is defined.
13259 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13260 where the include path doesn't have X11/X.h by default. See
13261 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13263 2011-05-20 Kenichi Handa <handa@m17n.org>
13265 * composite.c (find_automatic_composition): Fix previous change.
13267 2011-05-20 Glenn Morris <rgm@gnu.org>
13269 * lisp.mk: New file, split from Makefile.in.
13270 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13271 (shortlisp): Remove.
13272 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13274 2011-05-19 Glenn Morris <rgm@gnu.org>
13276 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13277 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13278 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13279 (lisp): Set the order to that of loadup.el.
13280 (shortlisp): Make it a copy of $lisp.
13281 (SOME_MACHINE_LISP): Remove.
13282 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13283 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13285 2011-05-18 Kenichi Handa <handa@m17n.org>
13287 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13288 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13289 (find_automatic_composition): Mostly rewrite for efficiency.
13291 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13293 * makefile.w32-in: Update dependencies.
13295 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13297 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13298 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13300 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13302 Fix some integer overflow issues, such as string length overflow.
13304 * insdel.c (count_size_as_multibyte): Check for string overflow.
13306 * character.c (lisp_string_width): Check for string overflow.
13307 Use EMACS_INT, not int, for string indexes and lengths; in
13308 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13309 the resulting string length overflows an EMACS_INT; instead,
13310 report a string overflow if no precision given. When checking for
13311 precision exhaustion, use a check that cannot possibly have
13312 integer overflow. (Bug#8675)
13313 * character.h (lisp_string_width): Adjust to new signature.
13315 * alloc.c (string_overflow): New function.
13316 (Fmake_string): Use it. This doesn't change behavior, but saves
13317 a few bytes and will simplify future changes.
13318 * character.c (string_escape_byte8): Likewise.
13319 * lisp.h (string_overflow): New decl.
13321 Fixups, following up to the user-interface timestamp change.
13322 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13323 for UI timestamps, instead of unsigned long.
13324 * msdos.c (mouse_get_pos): Likewise.
13325 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13326 * w32gui.h (Time): Define by including "systime.h" rather than by
13327 declaring it ourselves. (Bug#8664)
13329 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13330 * image.c (clear_image_cache): Likewise.
13332 * term.c (term_mouse_position): Don't assume time_t wraparound.
13334 Be more systematic about user-interface timestamps.
13335 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13336 and sometimes 'EMACS_UINT', to represent these timestamps.
13337 This change causes it to use 'Time' uniformly, as that's what X uses.
13338 This makes the code easier to follow, and makes it easier to catch
13339 integer overflow bugs such as Bug#8664.
13340 * frame.c (Fmouse_position, Fmouse_pixel_position):
13341 Use Time, not unsigned long, for user-interface timestamps.
13342 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13343 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13344 * keyboard.h (last_event_timestamp): Likewise.
13345 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13346 * menu.h (xmenu_show): Likewise.
13347 * term.c (term_mouse_position): Likewise.
13348 * termhooks.h (struct input_event.timestamp): Likewise.
13349 (struct terminal.mouse_position_hook): Likewise.
13350 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13351 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13352 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13353 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13354 what it was before.
13355 * menu.h, termhooks.h: Include "systime.h", for Time.
13357 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13358 Don't assume that the difference between two unsigned long values
13359 can fit into an integer. At this point, we know button_down_time
13360 <= event->timestamp, so the difference must be nonnegative, so
13361 there's no need to cast the result if double-click-time is
13362 nonnegative, as it should be; check that it's nonnegative, just in
13363 case. This bug is triggered when events are more than 2**31 ms
13364 apart (about 25 days). (Bug#8664)
13366 * xselect.c (last_event_timestamp): Remove duplicate decl.
13367 (x_own_selection): Remove needless cast to unsigned long.
13369 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13370 that always fit in int. Use a sentinel instead of a counter, to
13371 avoid a temp and to allay GCC's concerns about possible int overflow.
13372 * frame.h (struct frame): Use int for menu_bar_items_used
13373 instead of EMACS_INT, since it always fits in int.
13375 * menu.c (grow_menu_items): Check for int overflow.
13377 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13379 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13380 Before, the code was not consistent. These values cannot exceed
13381 2**31 - 1 so there's no need to make them unsigned.
13382 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13383 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13384 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13386 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
13388 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
13389 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
13390 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
13391 presumably because the widths might not match.
13393 * window.c (size_window): Avoid needless test at loop start.
13395 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
13397 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
13399 2011-05-12 Drew Adams <drew.adams@oracle.com>
13401 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
13403 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13405 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
13406 `width' to `bar_area_x' and `bar_area_width', respectively.
13407 (x_scroll_run): Take account of fringe background extension.
13409 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
13410 Rename local vars `left' and `width' to `bar_area_x' and
13411 `bar_area_width', respectively.
13412 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
13413 background extension.
13415 2011-05-10 Jim Meyering <meyering@redhat.com>
13417 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
13419 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
13421 * image.c (Finit_image_library): Return t for built-in image types,
13422 like pbm and xbm. (Bug#8640)
13424 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
13426 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13428 2011-05-07 Eli Zaretskii <eliz@gnu.org>
13430 * w32console.c (Fset_screen_color): Doc fix.
13431 (Fget_screen_color): New function.
13432 (syms_of_ntterm): Defsubr it.
13434 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
13435 unlink the temporary file if Fcall_process didn't create it in the
13437 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
13438 child process will be redirected to a file specified with `:file'.
13439 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
13440 cue to call_process_cleanup not to close that handle.
13442 2011-05-07 Ben Key <bkey76@gmail.com>
13444 * makefile.w32-in: The bootstrap-temacs rule now makes use of
13445 one of two shell specific rules, either bootstrap-temacs-CMD or
13446 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
13447 to the previous implementation of the bootstrap-temacs rule.
13448 The bootstrap-temacs-CMD rule is similar to the previous
13449 implementation of the bootstrap-temacs rule except that it
13450 makes use of the ESC_CFLAGS variable instead of the CFLAGS
13453 These changes, along with some changes to nt/configure.bat,
13454 nt/gmake.defs, and nt/nmake.defs, are required to extend my
13455 earlier fix to add support for --cflags and --ldflags options
13456 that include quotes so that it works whether make uses cmd or
13459 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
13461 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
13462 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
13464 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
13465 a string. Handle both cases.
13466 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
13467 (Fdbus_register_method): Use Qinvalid_function.
13469 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13471 * makefile.w32-in: Update dependencies.
13472 (LISP_H): Add inttypes.h and stdin.h.
13473 (PROCESS_H): Add unistd.h.
13475 2011-05-06 Eli Zaretskii <eliz@gnu.org>
13477 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13478 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13480 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13482 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13484 * term.c (vfatal): Remove stray call to va_end.
13485 It's not needed and the C Standard doesn't allow it here anyway.
13487 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13488 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13490 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13493 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13495 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13497 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13499 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13501 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13503 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13504 * charset.c (Fdefine_charset_internal): Don't initialize
13505 charset.code_space[15]. The value was garbage, on hosts with
13506 32-bit int (Bug#8600).
13508 * lread.c (read_integer): Be more consistent with string-to-number.
13509 Use string_to_number to do the actual conversion; this avoids
13510 rounding errors and fixes some other screwups. Without this fix,
13511 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13512 (digit_to_number): Move earlier, for benefit of read_integer.
13513 Return -1 if the digit is out of range for the base, -2 if it is
13514 not a digit in any supported base. (Bug#8602)
13516 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13518 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13519 to match comment at start of function. This also removes a
13520 GCC warning about overflow in a 32+64-bit port.
13522 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13524 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13525 Reported by Stefan Monnier in
13526 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13527 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13528 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13530 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13531 (EMACS_UINTPTR): Likewise, with uintptr_t.
13533 * lisp.h: Prefer 64-bit EMACS_INT if available.
13534 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13535 on 32-bit hosts that have 64-bit int, so that they can access
13537 However, temporarily disable this change unless the temporary
13538 symbol WIDE_EMACS_INT is defined.
13540 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13542 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13543 This removes an assumption that EMACS_INT and long are the same
13544 width as pointers. The assumption is true for Emacs porting targets
13545 now, but we want to make other targets possible.
13546 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13547 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13548 In the rest of the code, change types of integers that hold casted
13549 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13550 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13551 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13552 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13553 No need to cast type when ORing.
13554 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13555 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13556 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13557 assume EMACS_INT is the same width as char *.
13558 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13559 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13560 Remove no-longer-needed casts.
13561 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13562 (xg_tool_bar_help_callback, xg_make_tool_item):
13563 Use EMACS_INTPTR to hold an integer
13564 that will be cast to void *; this can avoid a GCC warning
13565 if EMACS_INT is not the same width as void *.
13566 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13567 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13568 (current_message_1, set_message_1):
13569 Use a local to convert to proper width without a cast.
13570 * xmenu.c (dialog_selection_callback): Likewise.
13572 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
13573 Also, don't assume VALBITS / RAND_BITS is less than 5,
13574 and don't rely on undefined behavior when shifting a 1 left into
13576 * lisp.h (get_random): Change signature to match.
13578 * lread.c (hash_string): Use size_t, not int, for hash computation.
13579 Normally we prefer signed values; but hashing is special, because
13580 it's better to use unsigned division on hash table sizes so that
13581 the remainder is nonnegative. Also, size_t is the natural width
13582 for hashing into memory. The previous code used 'int', which doesn't
13583 retain enough info to hash well into very large tables.
13584 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
13586 * dbusbind.c: Don't possibly lose pointer info when converting.
13587 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13588 Use XPNTR rather than XHASH, so that the high-order bits of
13589 the pointer aren't lost when converting through void *.
13591 * eval.c (Fautoload): Don't double-shift a pointer.
13593 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
13595 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13597 * gnutls.c (DEF_GNUTLS_FN):
13598 * image.c (DEF_IMGLIB_FN): Make function pointers static.
13600 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
13602 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
13605 2011-05-05 Eli Zaretskii <eliz@gnu.org>
13607 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
13608 New version that can reserve upto 2GB of heap space.
13610 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
13612 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
13614 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
13616 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
13617 `gnutls_certificate_set_x509_key_file'.
13619 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
13621 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
13622 Update dependencies.
13624 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13626 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
13627 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
13628 Remove unused parameter `fildes'.
13629 * process.c (read_process_output, send_process): Don't pass it.
13631 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13633 Fix previous change: the library cache is defined in w32.c.
13634 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
13635 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
13637 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13639 Implement dynamic loading of GnuTLS on Windows.
13641 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
13642 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
13643 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
13646 * gnutls.c (Qgnutls_dll): Define.
13647 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
13648 (gnutls_*): Declare function pointers.
13649 (init_gnutls_functions): New function to initialize function pointers.

13651 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
13652 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
13653 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
13654 (emacs_gnutls_write, emacs_gnutls_read)
13655 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
13656 (Fgnutls_available_p): New function.
13657 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
13658 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
13659 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
13661 * image.c: Include w32.h.
13662 (Vimage_type_cache): Delete.
13663 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
13664 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
13665 (w32_delayed_load): Move to w32.c.
13667 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
13669 * w32.c (QCloaded_from, Vlibrary_cache): Define.
13670 (w32_delayed_load): Move from image.c. When loading a library, record
13671 its filename in the :loaded-from property of the library id.
13672 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
13673 Initialize and staticpro them.
13674 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
13676 * process.c: Include lisp.h before w32.h, not after.
13677 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
13678 instead of gnutls_record_check_pending.
13680 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
13682 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
13684 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
13685 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
13688 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
13690 * xterm.c (x_set_frame_alpha): Do not set property on anything
13691 else than FRAME_X_OUTER_WINDOW (Bug#8608).
13693 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
13695 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
13697 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
13699 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
13700 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

13713 * sysdep.c (wait_for_termination_1): Make static.
13714 (wait_for_termination, interruptible_wait_for_termination):
13715 Move after wait_for_termination_1.
13717 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
13719 * sysdep.c (interruptible_wait_for_termination): New function
13720 which is like wait_for_termination, but allows keyboard
13723 * callproc.c (Fcall_process): Add (:file "file") as an option for
13725 (Fcall_process_region): Ditto.
13727 2011-04-30 Eli Zaretskii <eliz@gnu.org>
13729 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
13730 rather than `XVECTOR (FOO)->size'.
13732 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
13733 inttypes.h, as a gnulib replacement is used if it not available in
13736 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13738 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
13739 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
13740 of MOST_POSITIVE_FIXNUM. (Bug#8528)
13742 * coding.c (coding_alloc_by_realloc): Error out if destination
13743 will grow beyond MOST_POSITIVE_FIXNUM.
13744 (decode_coding_emacs_mule): Abort if there isn't enough place in
13745 charbuf for the composition carryover bytes. Reserve an extra
13746 space for up to 2 characters produced in a loop.
13747 (decode_coding_iso_2022): Abort if there isn't enough place in
13748 charbuf for the composition carryover bytes.
13750 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13752 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
13753 aborting when %lld or %lll format is passed.
13754 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
13755 %llo or %llx format is passed. (Bug#8545)
13757 * window.c (window_scroll_line_based): Use a marker instead of
13758 simple variables to record original value of point. (Bug#7952)
13760 * doprnt.c (doprnt): Fix the case where a multibyte sequence
13761 produced by %s or %c overflows available buffer space. (Bug#8545)
13763 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
13765 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
13766 (SIZE_MAX): Move defn after all includes, as they might #define it.
13768 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
13770 * w32.c (init_environment): Warn about defaulting HOME to C:\.
13772 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
13774 * keyboard.c (Qdelayed_warnings_hook): Define.
13775 (command_loop_1): Run `delayed-warnings-hook'
13776 if Vdelayed_warnings_list is non-nil.
13777 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
13778 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
13780 2011-04-28 Eli Zaretskii <eliz@gnu.org>
13782 * doprnt.c (doprnt): Don't return value smaller than the buffer
13783 size if the message was truncated. (Bug#8545).
13785 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
13787 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
13788 (Fx_window_property): #if-0 the whole functions, not just the bodies.
13790 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13792 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
13794 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
13796 * makefile.w32-in: Update dependencies.
13798 2011-04-27 Eli Zaretskii <eliz@gnu.org>
13800 Improve `doprnt' and its usage. (Bug#8545)
13801 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
13802 `format_end'. Remove support for %l as a conversion specifier.
13803 Don't use xrealloc. Improve diagnostics when the %l size modifier
13804 is used. Update the commentary.
13806 * eval.c (verror): Simplify calculation of size_t.
13808 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
13811 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
13813 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
13816 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13818 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
13819 This makes this file independent of the recent pseudovector change.
13821 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
13823 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
13825 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
13826 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
13827 Remove unused local.
13828 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
13830 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
13831 GCC 4.6.0 optimizes based on type-based alias analysis.
13832 For example, if b is of type struct buffer * and v of type struct
13833 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
13834 != &v->size, and therefore "v->size = 1; b->size = 2; return
13835 v->size;" must therefore return 1. This assumption is incorrect
13836 for Emacs, since it type-puns struct Lisp_Vector * with many other
13837 types. To fix this problem, this patch adds a new type struct
13838 vectorlike_header that documents the constraints on layout of vectors
13839 and pseudovectors, and helps optimizing compilers not get fooled
13840 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
13841 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
13842 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
13844 (XSETPVECTYPE): Rewrite in terms of new macro.
13845 (XSETPVECTYPESIZE): New macro, specifying both type and size.
13846 This is a bit clearer, and further avoids the possibility of
13847 undesirable aliasing.
13848 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
13849 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
13850 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
13851 since Lisp_Subr is a special case (no "next" field).
13852 (ASIZE): Now uses header.size rather than size.
13853 All previous uses of XVECTOR (foo)->size replaced to use this macro,
13854 to avoid the hassle of writing XVECTOR (foo)->header.size.
13855 (struct vectorlike_header): New type.
13856 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
13857 object, to help avoid aliasing.
13858 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
13859 (SUBRP): Likewise, since Lisp_Subr is a special case.
13860 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
13861 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
13862 (struct Lisp_Hash_Table): Combine first two members into a single
13863 struct vectorlike_header member. All uses of "size" and "next" members
13864 changed to be "header.size" and "header.next".
13865 * buffer.h (struct buffer): Likewise.
13866 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
13867 * frame.h (struct frame): Likewise.
13868 * process.h (struct Lisp_Process): Likewise.
13869 * termhooks.h (struct terminal): Likewise.
13870 * window.c (struct save_window_data, struct saved_window): Likewise.
13871 * window.h (struct window): Likewise.
13872 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
13873 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
13874 * buffer.c (init_buffer_once): Likewise.
13875 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
13877 * process.c (Fformat_network_address): Use local var for size,
13880 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
13882 Make the Lisp reader and string-to-float more consistent (Bug#8525)
13883 * data.c (atof): Remove decl; no longer used or needed.
13884 (digit_to_number): Move to lread.c.
13885 (Fstring_to_number): Use new string_to_number function, to be
13886 consistent with how the Lisp reader treats infinities and NaNs.
13887 Do not assume that floating-point numbers represent EMACS_INT
13888 without losing information; this is not true on most 64-bit hosts.
13889 Avoid double-rounding errors, by insisting on integers when
13890 parsing non-base-10 numbers, as the documentation specifies.
13891 * lisp.h (string_to_number): New decl, replacing ...
13892 (isfloat_string): Remove.
13893 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
13894 (read1): Do not accept +. and -. as integers; this
13895 appears to have been a coding error. Similarly, do not accept
13896 strings like +-1e0 as floating point numbers. Do not report
13897 overflow for integer overflows unless the base is not 10 which
13898 means we have no simple and reliable way to continue.
13899 Break out the floating-point parsing into a new
13900 function string_to_number, so that Fstring_to_number parses
13901 floating point numbers consistently with the Lisp reader.
13902 (digit_to_number): Move here from data.c. Make it static inline.
13903 (E_CHAR, EXP_INT): Remove, replacing with ...
13904 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
13905 (string_to_number): New function, replacing isfloat_string.
13906 This function checks for valid syntax and produces the resulting
13907 Lisp float number too. Rework it so that string-to-number
13908 no longer mishandles examples like "1.0e+". Use strtoumax,
13909 so that overflow for non-base-10 numbers is reported only when
13910 there's no portable and simple way to convert to floating point.
13912 * textprop.c (set_text_properties_1): Rewrite for clarity,
13913 and to avoid GCC warning about integer overflow.
13915 * intervals.h (struct interval): Use EMACS_INT for members
13916 where EMACS_UINT might cause problems. See
13917 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
13918 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
13919 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
13921 (offset_intervals): Tell GCC not to worry about length overflow
13922 when negating a negative length.
13924 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
13925 (overrun_check_free): Likewise.
13927 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
13928 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13931 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13932 (gnutls_make_error): Rename local to avoid shadowing.
13933 (gnutls_emacs_global_deinit): ifdef out; not used.
13934 (Fgnutls_boot): Use const for pointer to readonly storage.
13935 Comment out unused local. Fix pointer signedness problems.
13937 * lread.c (openp): Don't stuff size_t into an 'int'.
13938 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13939 about possible signed overflow.
13941 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13942 (GDK_KEY_g): Don't define if already defined.
13943 (xg_prepare_tooltip): Avoid pointer signedness problem.
13944 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13946 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13947 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13949 * xfns.c (Fx_window_property): Simplify a bit,
13950 to make a bit faster and to avoid GCC 4.6.0 warning.
13951 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13953 * fns.c (internal_equal): Don't assume size_t fits in int.
13955 * alloc.c (compact_small_strings): Tighten assertion a little.
13957 Replace pEd with more-general pI, and fix some printf arg casts.
13958 * lisp.h (pI): New macro, generalizing old pEd macro to other
13959 conversion specifiers. For example, use "...%"pI"d..." rather
13960 than "...%"pEd"...".
13961 (pEd): Remove. All uses replaced with similar uses of pI.
13962 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13963 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13964 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13965 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13966 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13967 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13968 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13970 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13971 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13972 * print.c (safe_debug_print, print_object): Likewise.
13973 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13975 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13976 avoiding the 0 flag, which is not portable.
13977 * process.c (Fmake_network_process): Use pI to avoid cast.
13978 * region-cache.c (pp_cache): Likewise.
13979 * xdisp.c (decode_mode_spec): Likewise.
13980 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13981 behavior on 64-bit hosts with printf arg.
13982 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13983 (x_stop_queuing_selection_requests): Likewise.
13984 (x_get_window_property): Don't truncate byte count to an 'int'
13987 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13988 here, since it parses constructs like leading '-' and spaces,
13989 which are not wanted; and it overflows with large numbers.
13990 Instead, simply match F[0-9]+, which is what is wanted anyway.
13992 * alloc.c: Remove unportable assumptions about struct layout.
13993 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13994 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13995 (allocate_vectorlike, make_pure_vector): Use the new macros,
13996 plus offsetof, to remove unportable assumptions about struct layout.
13997 These assumptions hold on all porting targets that I know of, but
13998 they are not guaranteed, they're easy to remove, and removing them
13999 makes further changes easier.
14001 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14002 This doesn't fix a bug but makes the code clearer.
14003 (string_overrun_cookie): Now const. Use initializers that
14004 don't formally overflow signed char, to avoid warnings.
14005 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14006 can cause Emacs to crash when string overrun checking is enabled.
14007 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14008 multiple of sizeof (EMACS_INT); it need not be, if
14009 alignof(EMACS_INT) < sizeof (EMACS_INT).
14010 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14012 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14039 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14041 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14042 "cast to pointer from integer of different size".
14044 Improve doprnt and its use in verror. (Bug#8545)
14045 * doprnt.c (doprnt): Document the set of format control sequences
14046 supported by the function. Use SAFE_ALLOCA instead of always
14049 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14050 is one byte too soon. Don't use xrealloc; instead xfree and
14053 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14055 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14058 * gnutls.c: Renamed global_initialized to
14059 gnutls_global_initialized. Added internals for the
14060 :verify-hostname-error, :verify-error, and :verify-flags
14061 parameters of `gnutls-boot' and documented those parameters in the
14062 docstring. Start callback support.
14063 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14064 unless a fatal error occurred. Call gnutls_alert_send_appropriate

14140 Many local variables are now size_t instead of int or unsigned.
14141 Improve overflow protection. Support `l' modifier for integer
14142 conversions. Support %l conversion. Don't assume an EMACS_INT
14143 argument for integer conversions and for %c.
14145 * lisp.h (doprnt): Restore prototype.
14147 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

14162 * callint.c (Fcall_interactively): When displaying error message
14163 about invalid control letter, pass the character's codepoint, not

14165 in octal and display also its hex code.
14167 * character.c (char_string): Use %x to display the (unsigned)
14168 codepoint of an invalid character, to avoid displaying a bogus
14171 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14172 `error', not SYMBOL_NAME itself.
14174 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

14250 * dispextern.h (struct redisplay_interface): Rename param
14251 to avoid shadowing.
14252 * termhooks.h (struct terminal): Likewise.

14369 * nsfont.m: Fixed bugs in ns_get_family and
14370 ns_descriptor_to_entity that were caused by using free to
14371 deallocate memory blocks that were allocated by xmalloc (via
14372 xstrdup). This caused Emacs to crash when compiled with
14373 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
14374 --enable-checking=xmallocoverrun). xfree is now used to
14375 deallocate these memory blocks.

14789 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
14790 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
14791 Remove decls, since these functions are now static.
14792 (Funintern, Fget_internal_run_time): New decls, since these functions
14793 were already external.
14795 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
14796 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

14802 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
14803 Mark functions with DEFUE instead of DEFUN,
14804 if they are used in other modules.
14805 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
14806 decls for now-static functions.
14807 * buffer.h (Fdelete_overlay): Remove decl.
14808 * callproc.c (Fgetenv_internal): Mark as internal.

14843 2011-04-13 Eli Zaretskii <eliz@gnu.org>
14845 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
14846 when at ZV. (Bug#8487)
14848 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
14850 * charset.c (Fclear_charset_maps): Use xfree instead of free.
14852 * keyboard.c (parse_tool_bar_item): Likewise.
14853 * sound.c (sound_cleanup, alsa_close): Likewise.
14854 * termcap.c (tgetent): Likewise.

14856 * xsettings.c (read_and_apply_settings): Likewise.
14858 * alloc.c (overrun_check_malloc, overrun_check_realloc)
14859 (overrun_check_free): Protoize.
14861 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
14863 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
14864 since callers should never pass a negative size.
14865 Change the signature to match that of plain 'read' and 'write'; see
14866 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
14867 * lisp.h: Update prototypes of emacs_write and emacs_read.
14869 2011-04-11 Eli Zaretskii <eliz@gnu.org>
14871 * xdisp.c (redisplay_window): Don't try to determine the character
14872 position of the scroll margin if the window start point w->startp
14873 is outside the buffer's accessible region. (Bug#8468)
14875 2011-04-10 Eli Zaretskii <eliz@gnu.org>
14877 Fix write-region and its subroutines for buffers > 2GB.
14878 * fileio.c (a_write, e_write): Modify declaration of arguments and
14879 local variables to support buffers larger than 2GB.
14880 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
14882 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
14883 argument, local variables, and return value.
14885 * lisp.h: Update prototypes of emacs_write and emacs_read.
14887 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
14889 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
14891 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
14893 Fix more problems found by GCC 4.6.0's static checks.
14895 * xdisp.c (vmessage): Use a better test for character truncation.
14897 * charset.c (load_charset_map): <, not <=, for optimization,
14898 and to avoid potential problems with integer overflow.
14899 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
14900 * casetab.c (set_identity, shuffle): Likewise.
14901 * editfns.c (Fformat): Likewise.
14902 * syntax.c (skip_chars): Likewise.
14904 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
14905 This also lets GCC 4.6.0 generate slightly better loop code.
14907 * callint.c (Fcall_interactively): <, not <=, for optimization.
14908 (Fcall_interactively): Count the number of arguments produced,
14909 not the number of arguments given. This is simpler and lets GCC
14910 4.6.0 generate slightly better code.
14912 * ftfont.c: Distingish more carefully between FcChar8 and char.
14913 The previous code passed unsigned char * to a functions like
14914 strlen and xstrcasecmp that expect char *, which does not
14915 conform to the C standard.
14916 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
14917 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
14918 char * when the C standard requires it.
14920 * keyboard.c (read_char): Remove unused var.
14922 * eval.c: Port to Windows vsnprintf (Bug#8435).
14923 Include <limits.h>.
14924 (SIZE_MAX): Define if the headers do not.
14925 (verror): Do not give up if vsnprintf returns a negative count.
14926 Instead, grow the buffer. This ports to Windows vsnprintf, which
14927 does not conform to C99. Problem reported by Eli Zaretskii.
14928 Also, simplify the allocation scheme, by avoiding the need for
14929 calling realloc, and removing the ALLOCATED variable.
14931 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14933 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14934 But keep the doprint source code for now, as we might revamp it
14935 and use it again (Bug#8435).
14936 * lisp.h (doprnt): Remove.
14937 * Makefile.in (base_obj): Remove doprnt.o.
14938 * deps.mk (doprnt.o): Remove.
14940 error: Print 32- and 64-bit integers portably (Bug#8435).
14941 Without this change, on typical 64-bit hosts error ("...%d...", N)
14942 was used to print both 32- and 64-bit integers N, which relied on
14943 undefined behavior.
14944 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14945 * lisp.h (error, verror): Mark as printf-like functions.
14946 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14947 Report overflow in size calculations when allocating printf buffer.
14948 Do not truncate output string at its first null byte.
14949 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14950 Truncate the output at a character boundary, since vsnprintf does not
14952 * charset.c (check_iso_charset_parameter): Convert internal
14953 character to string before calling 'error', since %c now has the
14955 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14956 overflow when computing char to be passed to 'error'. Do not
14957 pass Lisp_Object to 'error'; pass the integer instead.
14958 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14959 formatted with plain %d.
14961 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14963 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14965 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14967 * xterm.c (x_catch_errors): Remove duplicate declaration.
14969 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14971 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14973 2011-04-10 Jim Meyering <meyering@redhat.com>
14975 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14976 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14977 return ssize_t not "int", and use size_t as the buffer length.
14978 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14979 * gnutls.h: Update declarations.
14980 * process.c (read_process_output): Use ssize_t, to match.
14981 (send_process): Likewise.
14983 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14985 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14987 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14989 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14990 Use unsigned char, to match FcChar8 type definition.
14992 * xterm.c (handle_one_xevent):
14993 * xmenu.c (create_and_show_popup_menu):
14994 * xselect.c (x_decline_selection_request)
14995 (x_reply_selection_request): Avoid type-punned deref of X events.
14997 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14999 Fix some uses of `int' instead of EMACS_INT.
15000 * search.c (string_match_1, fast_string_match)
15001 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15002 (scan_buffer, find_next_newline_no_quit)
15003 (find_before_next_newline, search_command, Freplace_match)
15004 (Fmatch_data): Make some `int' variables be EMACS_INT.
15006 * xdisp.c (display_count_lines): 3rd argument and return value now
15007 EMACS_INT. All callers changed.
15008 (pint2hrstr): Last argument is now EMACS_INT.
15010 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15011 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

15023 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15024 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15026 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15027 (encode_invocation_designation): Last argument P_NCHARS is now
15029 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15030 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15032 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15035 * ccl.c (Fccl_execute_on_string): Declare some variables
15038 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15040 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15042 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15044 * process.c (Fformat_network_address): Doc fix.
15046 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15048 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15050 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15052 * keyboard.c (read_char): Call Lisp function help-form-show,
15053 instead of using internal_with_output_to_temp_buffer.
15054 (Qhelp_form_show): New var.
15055 (syms_of_keyboard): Use DEFSYM macro.
15057 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15059 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15061 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15063 * process.c (Flist_processes): Remove to Lisp.
15064 (list_processes_1): Delete.
15066 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15068 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15070 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15072 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15074 Fix more problems found by GCC 4.6.0's static checks.
15076 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15078 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15080 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15082 * xdisp.c (vmessage): Mark as a printf-like function.
15084 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15086 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15088 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15089 printf-like functions.
15090 (tiff_load): Add casts to remove these marks before passing them
15091 to system-supplied API.
15093 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15095 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15096 This avoids several warnings with gcc -Wstrict-overflow.
15097 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15098 directly, rather than having caller test rule sign. This avoids
15099 some unnecessary tests.
15100 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15101 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15102 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15104 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15105 (xfont_open): Avoid unnecessary tests.
15107 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15109 * composite.h, composite.c (composition_gstring_put_cache):
15110 Use EMACS_INT, not int, for length.

15113 breaking out part of COMPOSITION_DECODE_RULE.
15114 (COMPOSITION_DECODE_RULE): Use it.

15116 by using the new macro.
15118 * textprop.c (set_text_properties_1): Change while to do-while,
15119 since the condition is always true at first.
15121 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15122 (interval_deletion_adjustment): Return unsigned value.
15125 * process.c (list_processes_1, create_pty, read_process_output):

15135 (update_syntax_table): Use unsigned instead of int.
15137 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15138 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15139 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15141 * print.c (print_error_message): Avoid int overflow.
15143 * font.c (font_list_entities): Redo for clarity,
15144 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15146 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15147 (font_score): Avoid potential overflow in diff calculation.
15149 * fns.c (substring_both): Remove var that is set but not used.
15150 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15152 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15154 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15155 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15156 can always succeed if overflow has undefined behavior.
15158 * search.c (boyer_moore, wordify): Remove vars set but not used.
15159 (wordify): Omit three unnecessary tests.
15161 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15162 All callers changed. This avoids the need for an unused var.
15164 * casefiddle.c (casify_region): Remove var that is set but not used.
15166 * dired.c (file_name_completion): Remove var that is set but not used.
15168 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15170 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15171 (Finsert_file_contents): Remove unnecessary code checking fd.
15173 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15174 Check for integer overflow on size calculations.
15176 * buffer.c (Fprevious_overlay_change): Remove var that is set
15179 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15180 Remove vars that are set but not used.
15181 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15182 (timer_check_2): Mark vars as initialized.
15184 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15186 * image.c (lookup_image): Remove var that is set but not used.
15187 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15189 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15190 that are set but not used.
15192 * xfns.c (make_invisible_cursor): Don't return garbage
15193 if XCreateBitmapFromData fails (Bug#8410).
15195 * xselect.c (x_get_local_selection, x_handle_property_notify):
15196 Remove vars that are set but not used.
15198 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15199 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
15201 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
15202 Remove var that is set but not used.

15204 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15205 Check for overflow.
15207 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15208 (map_tty_color) [!defined MSDOS]: Likewise.
15210 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15212 * coding.c: Remove vars that are set but not used.
15213 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
15214 All callers changed.
15215 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
15216 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
15217 (decode_coding_charset): Remove vars that are set but not used.
15219 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
15220 that is set but not used.
15222 * print.c (print_object): Remove var that is set but not used.
15224 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15225 The gnulib version avoids calling malloc in the usual case,
15226 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15227 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15228 * filelock.c (current_lock_owner): Likewise.
15229 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
15230 * sysdep.c: Include allocator.h, careadlinkat.h.
15231 (emacs_no_realloc_allocator): New static constant.
15232 (emacs_readlink): New function.

15261 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15262 (ns_get_family): Likewise.
15264 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

15268 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15270 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15273 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15275 Add lexical binding.

15286 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15288 (syms_of_lread): Declare `lexical-binding'.
15290 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15292 * keyboard.c (eval_dyn): New fun.
15293 (menu_item_eval_property): Use it.

15297 * fns.c (concat, mapcar1): Accept byte-code-functions.
15299 * eval.c (Fsetq): Handle lexical vars.
15300 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15301 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15302 (FletX, Flet): Obey lexical binding.
15303 (Fcommandp): Handle closures.
15304 (Feval): New `lexical' arg.
15305 (eval_sub): New function extracted from Feval. Use it almost
15306 everywhere where Feval was used. Look up vars in lexical env.
15308 (Ffunctionp): Move from subr.el.
15309 (Ffuncall): Handle closures.
15310 (apply_lambda): Remove `eval_flags'.
15311 (funcall_lambda): Handle closures and new byte-code-functions.
15312 (Fspecial_variable_p): New function.
15313 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15314 but without exporting it to Lisp.
15316 * doc.c (Fdocumentation, store_function_docstring):
15317 * data.c (Finteractive_form): Handle closures.
15319 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15322 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15324 (exec_byte_code): New function extracted from Fbyte_code to handle new
15325 calling convention for byte-code-functions. Add new byte-codes.
15327 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

15333 * xdisp.c (redisplay_internal): Fix prototype.
15335 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15337 * xdisp.c (SCROLL_LIMIT): New macro.
15338 (try_scrolling): Use it when setting scroll_limit.
15339 Limit scrolling to 100 screen lines.
15340 (redisplay_window): Even when falling back on "recentering",
15341 position point in the window according to scroll-conservatively,
15342 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15344 (try_scrolling): When point is above the window, allow searching
15345 as far as scroll_max, or one screenful, to compute vertical
15346 distance from PT to the scroll margin position. This prevents
15347 try_scrolling from unnecessarily failing when
15348 scroll-conservatively is set to a value slightly larger than the
15349 window height. Clean up the case of PT below the margin at bottom
15350 of window: scroll_max can no longer be INT_MAX. When aggressive
15351 scrolling is in use, don't let point enter the opposite scroll
15352 margin as result of the scroll.
15353 (syms_of_xdisp) <scroll-conservatively>: Document the
15354 threshold of 100 lines for never-recentering scrolling.
15356 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

15364 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15366 * indent.c (Fvertical_motion):
15367 * window.c (window_scroll_pixel_based, Frecenter):
15368 Don't pass `need_y_p' to `move_it_by_lines'.
15370 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15372 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15373 steal a few bits to be more compact.
15374 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15375 Remove unneeded casts.
15377 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15379 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15381 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15382 binding" message (bug#7967).
15384 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15386 Fix more problems found by GCC 4.6.0's static checks.
15388 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
15389 Remove unused local var.
15391 * editfns.c (Fmessage_box): Remove unused local var.
15393 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
15394 (note_mode_line_or_margin_highlight, note_mouse_highlight):
15395 Omit unused local vars.
15396 * window.c (shrink_windows): Omit unused local var.
15397 * menu.c (digest_single_submenu): Omit unused local var.
15398 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
15399 Omit unused local var.
15401 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
15402 Don't assume string length fits in int.
15403 (keyremap_step, read_key_sequence): Use size_t for sizes.
15404 (read_key_sequence): Don't check last_real_key_start redundantly.
15406 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
15407 instead of alloca (Bug#8344).
15409 * eval.c (Fbacktrace): Don't assume nargs fits in int.
15410 (Fbacktrace_frame): Don't assume nframes fits in int.
15412 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

15419 * cm.c (calccost): Turn while-do into do-while, for clarity.
15421 * keyboard.c (syms_of_keyboard): Use the same style as later
15422 in this function when indexing through an array. This also
15423 works around GCC bug 48267.
15425 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
15427 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
15429 * chartab.c (sub_char_table_ref_and_range): Redo for slight
15430 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
15432 * keyboard.c, keyboard.h (num_input_events): Now size_t.
15433 This avoids undefined behavior on integer overflow, and is a bit
15434 more convenient anyway since it is compared to a size_t variable.
15436 Variadic C functions now count arguments with size_t, not int.
15437 This avoids an unnecessary limitation on 64-bit machines, which
15438 caused (substring ...) to crash on large vectors (Bug#8344).

15448 * fns.c (concat): Likewise.
15449 * frame.c (x_set_frame_parameters): Likewise.
15450 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
15451 0 if not found, not -1. All callers changed.
15453 * alloc.c (garbage_collect): Don't assume stack size fits in int.
15454 (stack_copy_size): Now size_t, not int.
15455 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
15457 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

15476 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
15477 don't set the hook to nil, but remove the offending function instead.
15478 (Qcommand_hook_internal): Remove, unused.
15479 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
15480 Vcommand_hook_internal.
15482 * eval.c (enum run_hooks_condition): Remove.
15483 (funcall_nil, funcall_not): New functions.
15484 (run_hook_with_args): Call each function through a `funcall' argument.

15670 * coding.c (encode_coding_raw_text): Avoid unnecessary test
15671 the first time through the loop, since we know p0 < p1 then.
15672 This also avoids a gcc -Wstrict-overflow warning.
15674 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
15675 leading to a memory leak, possible in functions like
15676 load_charset_map_from_file that can allocate an unbounded number
15677 of objects (Bug#8318).
15679 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
15680 that could (at least in theory) be that large.
15682 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
15683 This is less likely to overflow, and avoids undefined behavior if
15684 overflow does occur. All callers changed. Use strtoul to scan
15685 for the unsigned long integer.
15686 (pint2hrstr): Simplify and tune code slightly.
15687 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
15689 * scroll.c (do_scrolling): Work around GCC bug 48228.
15690 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
15692 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
15693 This also avoids a warning with gcc -Wstrict-overflow.
15694 (validate_x_resource_name): Simplify count usage.
15695 This also avoids a warning with gcc -Wstrict-overflow.
15697 * fileio.c (Fcopy_file): Report error if fchown or fchmod
15700 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
15702 * process.c (Fmake_network_process): Use socklen_t, not int,
15703 where POSIX says socklen_t is required in portable programs.
15704 This fixes a porting bug on hosts like 64-bit HP-UX, where
15705 socklen_t is wider than int (Bug#8277).
15706 (Fmake_network_process, server_accept_connection):
15707 (wait_reading_process_output, read_process_output):
15710 * process.c: Rename or move locals to avoid shadowing.
15711 (list_processes_1, Fmake_network_process):
15712 (read_process_output_error_handler, exec_sentinel_error_handler):
15713 Rename or move locals.
15714 (Fmake_network_process): Define label "retry_connect" only if needed.
15715 (Fnetwork_interface_info): Fix pointer signedness.
15716 (process_send_signal): Add cast to avoid pointer signedness problem.
15717 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
15718 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
15720 Make tparam.h and terminfo.c consistent.
15721 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
15722 Include tparam.h instead, since it declares them.
15723 * cm.h (PC): Remove extern decl; tparam.h now does this.
15724 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
15725 * terminfo.c: Include tparam.h, to check interfaces.
15726 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
15727 (tparam): Adjust signature to match interface in tparam.h;
15728 this removes some undefined behavior. Check that outstring and len
15729 are zero, which they always are with Emacs.
15730 * tparam.h (PC, BC, UP): New extern decls.
15732 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
15733 (xftfont_open): Rename locals to avoid shadowing.
15735 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

15737 (OTF_TAG_SYM): Omit macro if not needed.
15738 (ftfont_list): Remove unused local.
15739 (get_adstyle_property, ftfont_pattern_entity):
15740 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):

15745 * xml.c (make_dom): Now static.
15747 * composite.c (composition_compute_stop_pos): Rename local to
15749 (composition_reseat_it): Remove unused locals.
15750 (find_automatic_composition, composition_adjust_point): Likewise.
15751 (composition_update_it): Mark var as initialized.
15752 (find_automatic_composition): Mark vars as initialized,
15753 with a FIXME (Bug#8290).

15757 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
15758 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
15759 (BUF_DEC_POS): Be more systematic about renaming local temporaries
15760 to avoid shadowing.
15762 * textprop.c (property_change_between_p): Remove; unused.
15764 * intervals.c (interval_start_pos): Now static.
15766 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

15769 Rename locals to avoid shadowing.
15771 * sound.c (wav_play, au_play, Fplay_sound_internal):
15772 Fix pointer signedness.
15773 (alsa_choose_format): Remove unused local var.
15774 (wav_play): Initialize a variable to 0, to prevent undefined
15775 behavior (Bug#8278).
15777 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
15779 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
15781 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
15782 clobbering (Bug#8298).
15783 * sysdep.c (sys_subshell): Likewise.
15784 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
15786 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
15787 This should get cleaned up, so that child_setup has the
15788 same signature on all platforms.
15790 * callproc.c (call_process_cleanup): Now static.
15791 (relocate_fd): Rename locals to avoid shadowing.
15793 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
15795 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
15796 not to be necessary, and produces flickering.
15798 2011-03-20 Glenn Morris <rgm@gnu.org>
15800 * config.in: Remove file.
15802 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
15804 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
15805 are now in src/globals.h.
15806 (syms_of_minibuf): Remove spurious & from previous change.
15808 2011-03-20 Leo Liu <sdl.web@gmail.com>
15810 * minibuf.c (completing-read-function): New variable.
15811 (completing-read-default): Rename from completing-read.
15812 (completing-read): Call completing-read-function.
15814 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
15816 * xfaces.c (Fx_load_color_file):
15817 Read color file from absolute filename (bug#8250).
15819 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
15821 * makefile.w32-in: Update dependencies.
15823 2011-03-17 Eli Zaretskii <eliz@gnu.org>
15825 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

15832 (sigchld_handler): Now static.
15834 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

15845 (CONSTANTLIM): Remove; unused.
15846 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
15847 Define only if needed.
15849 * unexelf.c (unexec): Name an expression,
15850 to avoid gcc -Wbad-function-cast warning.
15851 Use a different way to cause a compilation error if anyone uses
15852 n rather than nn, a way that does not involve shadowing.
15853 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
15855 * deps.mk (unexalpha.o): Remove; unused.
15857 New file unexec.h, the (simple) interface for unexec (Bug#8267).
15858 * unexec.h: New file.
15859 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
15860 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
15861 Depend on unexec.h.
15862 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
15863 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
15864 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
15865 Change as necessary to match prototype in unexec.h.

15900 * floatfns.c (domain_error2): Define only if needed.
15901 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
15903 * alloc.c (mark_backtrace): Move decl from here ...

15912 * callint.c (quotify_arg, quotify_args): Now static.
15913 (Fcall_interactively): Rename locals to avoid shadowing.
15914 Use const pointer when appropriate.

15920 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
15921 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
15922 some of which prompt warnings from gcc -Wbad-function-cast.
15923 (Fformat_time_string, Fencode_time, Finsert_char):
15924 (Ftranslate_region_internal, Fformat):
15925 Rename or remove local vars to avoid shadowing.

15928 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
15931 * lisp.h (eassert): Check that the argument compiles, even if

15950 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
15951 (GC_STRING_CHARS): Remove; not used.
15952 (Fmemory_limit): Cast sbrk's returned value to char *.
15954 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
15955 avoids undefined behavior in theory.
15957 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
15959 Use functions, not macros, for up- and down-casing (Bug#8254).
15960 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15961 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15962 to use the following functions instead of these macros.
15963 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15964 EMACS_INT, since callers assume the returned value fits in int.
15965 (upcase1): Likewise, for UPCASE_TABLE.
15966 (uppercasep, lowercasep, upcase): New static inline functions.
15967 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15976 which gcc can warn about.
15977 (regex_compile, re_match_2_internal): Mark locals as initialized.
15978 (RETALLOC_IF): Define only if needed.
15979 (WORDCHAR_P): Likewise. This one is never needed, but is used
15980 only in a comment talking about a compiler bug, so put inside
15981 the #if 0 of that comment.
15982 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15983 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
15986 * search.c (boyer_moore): Rename locals to avoid shadowing.
15987 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
15988 (PREV_CHAR_BOUNDARY): Likewise.

16000 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16001 Rename locals to avoid shadowing.
16002 (Fvertical_motion): Mark locals as initialized.
16004 * casefiddle.c (casify_object, casify_region): Now static.
16005 (casify_region): Mark local as initialized.
16007 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16009 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16010 New macros, so that the caller can use some names other than
16011 gcpro1, gcpro2, etc.
16012 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16014 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16015 argument, for consistency with GCPRO2_VAR, etc: it is now the
16016 prefix of the variable, not the variable itself. All uses
16018 * dired.c (directory_files_internal, file_name_completion):
16019 Rename locals to avoid shadowing.
16021 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16022 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16023 dired.c's scmp function, had undefined behavior.
16024 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16025 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16026 * buffer.h: ... to here, because these macros use current_buffer,
16027 and the new implementation with inline functions needs to have
16028 current_buffer in scope now, rather than later when the macros
16030 (downcase, upcase1): New static inline functions.
16031 (DOWNCASE, UPCASE1): Reimplement using these functions.
16032 This avoids undefined behavior in expressions like
16033 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16034 from race conditions in accessing the global variables
16035 case_temp1 and case_temp2.
16036 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16037 * lisp.h (case_temp1, case_temp2): Remove their decls.
16038 * character.h (ASCII_CHAR_P): Move from here ...
16039 * lisp.h: ... to here, so that the inline functions mentioned
16040 above can use them.
16042 * dired.c (directory_files_internal_unwind): Now static.
16044 * fileio.c (file_name_as_directory, directory_file_name):
16045 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16047 (file_name_as_directory): Use const pointers when appropriate.
16048 (Fexpand_file_name): Likewise. In particular, newdir might
16049 point at constant storage, so make it a const pointer.
16050 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16051 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16053 (Fset_file_times, Finsert_file_contents, auto_save_error):
16054 Rename locals to avoid shadowing.

16058 to avoid shadowing.
16060 * marker.c (bytepos_to_charpos): Remove; unused.
16062 * lisp.h (verify_bytepos, count_markers): New decls,
16063 so that gcc does not warn that these functions aren't declared.
16065 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16066 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16067 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16068 (copy_text): Remove unused local var.
16070 * filelock.c (within_one_second): Now static.
16071 (lock_file_1): Rename local to avoid shadowing.
16073 * buffer.c (fix_overlays_before): Mark locals as initialized.
16074 (fix_start_end_in_overlays): Likewise. This function should be
16075 simplified by using pointers-to-pointers, but that's a different
16077 (switch_to_buffer_1): Now static.
16078 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16079 (report_overlay_modification): Rename locals to avoid shadowing.
16081 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16082 Fix pointer signedness issue.
16083 (sys_subshell): Mark local as volatile if checking for lint,
16084 to suppress a gcc -Wclobbered warning that does not seem to be right.
16085 (MAXPATHLEN): Define only if needed.
16087 * process.c (serial_open, serial_configure): Move decls from here ...
16088 * systty.h: ... to here, so that they can be checked.
16090 * fns.c (get_random, seed_random): Move extern decls from here ...
16091 * lisp.h: ... to here, so that they can be checked.
16093 * sysdep.c (reset_io): Now static.
16094 (wait_for_termination_signal): Remove; unused.
16096 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
16097 (copy_keymap_item, append_key, push_text_char_description):
16099 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
16100 (DENSE_TABLE_SIZE): Remove; unused.
16101 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
16102 (describe_map_tree):
16103 Rename locals to avoid shadowing.
16105 * keyboard.c: Declare functions static if they are not used elsewhere.
16106 (echo_char, echo_dash, cmd_error, top_level_2):
16107 (poll_for_input, handle_async_input): Now static.
16108 (read_char, kbd_buffer_get_event, make_lispy_position):
16109 (make_lispy_event, make_lispy_movement, apply_modifiers):
16110 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
16111 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
16112 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
16113 (read_key_sequence, read_char): Mark locals as initialized.
