[emacs.git] / src / ChangeLog

2011-09-04  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c: Integer overflow fix.
        (try_window_id): Check Emacs fixnum range before converting to 'int'.

        * window.c: Integer overflow fixes.
        (window_scroll_line_based, Frecenter):
        Check that an Emacs fixnum is in range before assigning it to 'int'.
        (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
        values converted from Emacs fixnums.
        (Frecenter): Don't wrap around a line count if it is out of 'int'
        range; instead, treat it as an extreme value.
        (Fset_window_configuration, compare_window_configurations):
        Use ptrdiff_t, not int, for index that might exceed 2 GiB.

        * search.c: Integer overflow fixes
        (Freplace_match): Use ptrdiff_t, not int, for indexes that can
        exceed INT_MAX.  Check that EMACS_INT value is in range before
        assigning it to the (possibly-narrower) index.
        (match_limit): Don't assume that a fixnum can fit in 'int'.

        * print.c: Integer overflow fix.
        (print_object): Use ptrdiff_t, not int, for index that can
        exceed INT_MAX.

        * indent.c: Integer overflow fixes.
        (position_indentation): Now takes ptrdiff_t, not int.
        (Fvertical_motion): Don't wrap around LINES values that don't fit
        in 'int'.  Instead, treat them as extreme values.  This is good
        enough for windows, which can't have more than INT_MAX lines anyway.

2011-09-03  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * Require libxml/parser.h to avoid compilation warning.

        * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.

        * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
        since this reportedly can destroy thread storage.

2011-08-30  Chong Yidong  <cyd@stupidchicken.com>

        * syntax.c (find_defun_start): Update all cache variables if
        exiting early (Bug#9401).

2011-08-30  Eli Zaretskii  <eliz@gnu.org>

        * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.

        * xdisp.c (produce_stretch_glyph): No longer static, compiled also
        when HAVE_WINDOW_SYSTEM is not defined.  Support both GUI and TTY
        frames.  Call tty_append_glyph in the TTY case.  (Bug#9402)

        * term.c (tty_append_glyph): New function.
        (produce_stretch_glyph): Static function and its prototype deleted.

        * dispextern.h (produce_stretch_glyph, tty_append_glyph): Add
        prototypes.

2011-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (parse_image_spec): Check for nonnegative, not for positive,
        when checking :margin (Bug#9390).
        (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
        Renamed from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
        so that the name doesn't mislead.  All uses changed.

2011-08-28  Johan Bockgård  <bojohan@gnu.org>

        * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
        set_tty_hooks.

2011-08-27  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (move_it_to): Don't bail out early when reaching
        position beyond to_charpos, if we are scanning backwards.
        (move_it_vertically_backward): When DY == 0, make sure we get to
        the first character in the line after the newline.

2011-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        * ccl.c: Improve and simplify overflow checking (Bug#9196).
        (ccl_driver): Do not generate an out-of-range pointer.
        (Fccl_execute_on_string): Remove unnecessary check for
        integer overflow, noted by Stefan Monnier in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
        Remove a FIXME that didn't need fixing.
        Simplify the newly-introduced buffer reallocation code.

2011-08-27  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.

2011-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        Integer and memory overflow issues (Bug#9196).

        * doc.c (get_doc_string): Rework so that
        get_doc_string_buffer_size is the actual buffer size, rather than
        being 1 less than the actual buffer size; this makes xpalloc more
        convenient.

        * image.c (x_allocate_bitmap_record, cache_image):
        * xselect.c (Fx_register_dnd_atom):
        Simplify previous changes by using xpalloc.

        * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
        since either will do and ptrdiff_t is convenient with xpalloc.

        * charset.c (charset_table_size)
        (struct charset_sort_data.priority): Now ptrdiff_t.
        (charset_compare): Don't overflow if priorities differ greatly.
        (Fsort_charsets): Don't assume list length fits in int.
        Check for size-calculation overflow when allocating sort data.
        (syms_of_charset): Allocate an initial charset table that is
        just under 64 KiB, to avoid problems with glibc malloc and mmap.

        * cmds.c (internal_self_insert): Check for size-calculation overflow.

        * composite.h (struct composition.glyph_len): Now int, not unsigned.
        The actual value is always <= INT_MAX, and leaving it unsigned made
        overflow checking harder.

        * dispextern.h (struct glyph_matrix.rows_allocated)
        (struct face_cache.size): Now ptrdiff_t, for convenience in use
        with xpalloc.  The values are still always <= INT_MAX.

        * indent.c (compute_motion): Adjust to region_cache_forward sig change.

        * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
        (SAFE_NALLOCA): New macro.

        * region-cache.c (struct boundary.pos, find_cache_boundary)
        (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
        (set_cache_region, invalidate_region_cache)
        (revalidate_region_cache, know_region_cache, region_cache_forward)
        (region_cache_backward, pp_cache):
        Use ptrdiff_t, not EMACS_INT, since either will do.  This is needed
        so that ptrdiff_t * can be passed to xpalloc.
        (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
        beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
        (pp_cache): Don't assume cache_len fits in int.
        * region-cache.h: Adjust extern decls to match.

        * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
        EMACS_INT, since either will do, for xpalloc.

        * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
        (xnmalloc, xnrealloc, xpalloc): New functions.

        * bidi.c (bidi_shelve_header_size): New constant.
        (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
        (bidi_cache_ensure_space): Avoid integer overflow when allocating.

        * bidi.c (bidi_cache_shrink):
        * buffer.c (overlays_at, overlays_in, record_overlay_string)
        (overlay_strings):
        Don't update size of array until after memory allocation succeeds,
        because xmalloc/xrealloc may not return.
        (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
        now that we have proper integer overflow checking.
        (record_overlay_string, overlay_strings): Catch overflows when
        calculating size of overlay_str_buf.

        * callproc.c (Fcall_process): Check for size overflow when
        calculating size of args2.
        (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
        Normally we prefer signed values, but sticking with ptrdiff_t would
        require adding more-complicated checks.

        * ccl.c (Fccl_execute_on_string): Check for memory overflow.
        Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
        Redo buffer-overflow calculations to avoid integer overflow.
        Add a FIXME comment where memory seems to be over-allocated.

        * character.c (Fstring): Check for size-calculation overflow.

        * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
        unnecessary integer overflow.  Check for size overflow.
        (encode_coding_object): Don't update size until xmalloc succeeds.

        * composite.c (get_composition_id): Check for overflow in glyph
        length calculations.

        Integer and memory overflow fixes for display code.
        * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
        * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
        (scrolling_window): Check for overflow in size calculations.
        (line_draw_cost, realloc_glyph_pool, add_row_entry):
        Don't assume glyph table len fits in int.
        (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
        (row_table_size): Now ptrdiff_t, not int.
        (scrolling_window): Avoid overflow in size calculations.
        Don't update size until allocation succeeds.
        * fns.c (concat): Check for overflow in size calculations.
        (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
        * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

        Don't update size until allocation succeeds.
        (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
        EMACS_INT, where ptrdiff_t will do.
        (Fsubstitute_command_keys): Check for string overflow.

        * editfns.c (set_time_zone_rule): Don't assume environment length
        fits in int.

        (Fmessage_box): Don't update size until allocation succeeds.
        Don't assume message length fits in int.
        (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.

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

        * eval.c (init_eval_once, grow_specpdl): Don't update size until
        alloc succeeds.
        (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

        * frame.c (set_menu_bar_lines, x_set_frame_parameters)
        (x_set_scroll_bar_width, x_figure_window_size):
        Check for integer overflow.
        (x_set_alpha): Do not assume XINT fits in int.

        * frame.h (struct frame): Use int, not EMACS_INT, where int works.
        This is for the members text_lines, text_cols, total_lines, total_cols,
        where the system imposes an 'int' limit.

        * fringe.c (Fdefine_fringe_bitmap):
        Don't update size until alloc works.

        * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
        (ftfont_shape_by_flt): Check for integer overflow in size calculations.

        * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
        Check for size-calculation overflow.
        (get_utf8_string): Use ptrdiff_t, not size_t, where either will
        do, as we prefer signed integers.
        (id_to_widget.max_size, id_to_widget.used)
        (xg_store_widget_in_map, xg_remove_widget_from_map)
        (xg_get_widget_from_map, xg_get_scroll_id_for_window)
        (xg_remove_scroll_bar, xg_update_scrollbar_pos):
        Use and return ptrdiff_t, not int.
        (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
        * gtkutil.h: Change prototypes to match the above.

        * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
        are duplicate now that they've been promoted to lisp.h.
        (x_allocate_bitmap_record, x_alloc_image_color)
        (make_image_cache, cache_image, xpm_load):

        (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
        Use ptrdiff_t, not int, to count maps.

        for command line length.  Do not attempt to address one before the
        beginning of an array, as that's not portable.

        (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
        not int.

        * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
        Don't update size until alloc done.
        Redo size calculations to avoid overflow.
        Check for size calculation overflow.

        (xg_select): Check for size calculation overflow.
        Don't update size until alloc done.

        as sprintf is limited to int lengths.

        * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
        (X_LONG_MIN): New macros.
        Use them to make the following changes clearer.
        (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
        This change doesn't affect the value now, but it may help remind
        future maintainers not to raise the value too much later.
        (SELECTION_QUANTUM): Remove, replacing with ...
        (selection_quantum): ... new function, which avoids overflow.
        All uses changed.
        (struct selection_data.size): Now ptrdiff_t, not int, to avoid
        assumption that selection length fits in 'int'.
        (x_reply_selection_request, x_handle_selection_request)
        (x_get_window_property, receive_incremental_selection)
        (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
        (lisp_data_to_selection_data, clean_local_selection_data):
        Use ptrdiff_t, not int, to record length of selection.
        (x_reply_selection_request, x_get_window_property)

        Redo calculations to avoid overflow.

        Don't store size until memory allocation succeeds.
        (x_get_window_property): Plug memory leak on memory exhaustion.
        Don't double-block input; malloc is safe here.  Don't assume 2**34
        - 4 fits in unsigned long.  Add an xassert to check
        XGetWindowProperty overflow.  Be more careful about overflow
        calculations, and distinguish size from memory overflow better.
        (receive_incremental_selection): When tracing, don't assume
        unsigned int is less than INT_MAX.
        (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
        harmful) conversions of unsigned short to int.
        (lisp_data_to_selection_data): Don't assume that integers
        in the range -65535 through -1 fit in an X unsigned short.
        Don't assume that ULONG_MAX == X_ULONG_MAX.  Don't store into
        result parameters unless successful.  Rely on cons_to_unsigned
        to report problems with elements; the old code wasn't right anyway.
        (x_check_property_data): Check for int overflow; we cannot use
        a wider type due to X limits.
        (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

        * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

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

        * charset.c (Fdefine_charset_internal): Check for integer overflow.
        Add a FIXME comment about memory leaks.
        (syms_of_charset): Don't assume xmalloc returns.

        Use sanitize_char_width to avoid undefined and/or bad behavior
        with outlandish widths.
        * character.h (sanitize_tab_width): Renamed from sanitize_width,
        now that we have two such functions.  All uses changed.
        (sanitize_char_width): New inline function.

        Remove unreachable code.
        (read_hex, load_charset_map_from_file): Check for integer overflow.

        * xterm.c: don't go over XClientMessageEvent limit
        (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
        (x_send_scroll_bar_event): Likewise.  Check that the size does not
        exceed limits imposed by XClientMessageEvent, as well as the usual
        ptrdiff_t and size_t limits.

        * keyboard.c: Overflow, signedness and related fixes.
        (make_lispy_movement): Use same integer type in forward decl
        that is used in the definition.
        (read_key_sequence, keyremap_step):
        Change bufsize argument back to int, undoing my 2011-03-30 change.
        We prefer signed types, and int is wide enough here.
        (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
        than TYPE_MAXIMUM (EMACS_INT) / 2.  Don't let the label size grow
        larger than STRING_BYTES_BOUND.  Use ptrdiff_t for Emacs string
        length, not size_t.  Use ptrdiff_t for index, not int.
        (keyremap_step, read_key_sequence): Redo bufsize check to avoid
        possibility of integer overflow.

        Overflow, signedness and related fixes for images.

        (lookup_image): Remove unnecessary tests.
        (xbm_image_p): Locals are now of int, not EMACS_INT,
        since parse_image_check makes sure they fit into int.
        (png_load, gif_load, svg_load_image):
        Prefer int to unsigned where either will do.
        (tiff_handler): New function, combining the cores of the
        old tiff_error_handler and tiff_warning_handler.  This
        function is rewritten to use vsnprintf and thereby avoid
        stack buffer overflows.  It uses only the features of vsnprintf
        that are common to both POSIX and native Microsoft.
        (tiff_error_handler, tiff_warning_handler): Use it.
        (tiff_load, gif_load, imagemagick_load_image):
        Don't assume :index value fits in 'int'.
        (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
        (imagemagick_load_image): Check that crop parameters fit into
        the integer types that MagickCropImage accepts.  Don't assume
        Vimagemagick_render_type has a nonnegative value.  Don't assume
        size_t fits in 'long'.
        (gs_load): Use printmax_t to print the widest integers possible.

        the display spec is of the form `(space ...)'.
        (handle_display_spec): Return the value returned by
        handle_single_display_spec, not just 1 or zero.
        (handle_single_display_spec): If the display spec is of the form
        `(space ...)', and specifies display in the text area, return 2
        rather than 1.
        (try_cursor_movement): Check for the need to scroll more
        accurately, and prefer exact match for point under bidi.  Don't
        advance `row' beyond the last row of the window.

        positioning on the newline at EOL of R2L text within L2R
        paragraph, and vice versa.
        (try_cursor_movement): Check continued rows, in addition to
        continuation rows.  Fixes unwarranted scroll when point enters a

        (cursor_row_p): Consider the case of point being equal to
        MATRIX_ROW_END_CHARPOS.  Prevents cursor being stuck when moving
        from the end of a short line to the beginning of a continued line
        of R2L text within L2R paragraph.
        (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

        composed character under the mouse.

        * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1.  Fixes pixel
        coordinates reported by pos-visible-in-window-p for a composed

        consider it a hit if to_charpos is anywhere in the range of the
        composed buffer positions.

2011-08-22  Chong Yidong  <cyd@stupidchicken.com>

        * image.c (gif_load): Don't assume that each subimage has the same
        dimensions as the base image.  Handle disposal method that is
        "undefined" by the gif spec (Bug#9335).

2011-08-20  Chong Yidong  <cyd@stupidchicken.com>

        with a composed character.

2011-08-18  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
        character bidirectional type, use STRONG_L instead.  Fixes crashes
        in a buffer produced by `describe-categories'.

        * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
        members before the level stack, so they would be saved and
        restored when copying iterator state.  Fixes incorrect reordering
        around TABs covered by display properties.

        Set IT->current to match the bidi iterator unconditionally.
        (push_display_prop): Allow GET_FROM_STRING as IT->method on
        entry.  Force push_it to save on the stack the current
        buffer/string position, to be restored by pop_it.  Fix flags in
        the iterator structure wrt the object coming from a display
        property, as `line-prefix' and `wrap-prefix' are not ``replacing''
        properties.  (Bug#9284)

        (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
        non-zero, only free the data buffer without restoring the cache
        contents.  All callers changed.

        * dispextern.h (bidi_unshelve_cache): Update prototype.

        (move_it_in_display_line_to): Fix logic of returning
        MOVE_POS_MATCH_OR_ZV in the bidi case.  (Bug#9224)

2011-08-05  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
        came from a string character with a `cursor' property.  (Bug#9229)

2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>

        * Makefile.in (LIB_PTHREAD): New variable.

        * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
        Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

2011-08-04  Andreas Schwab  <schwab@linux-m68k.org>

        * regex.c (re_iswctype): Remove some redundant boolean
        conversions.

2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>

        * xterm.c (x_find_topmost_parent): New function.
        (x_set_frame_alpha): Find topmost parent window with
        x_find_topmost_parent and set the property there also (bug#9181).
        (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.

2011-08-04  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (Fcall_process): Avoid vfork clobbering
        the local vars buffer, coding_systems, current_dir.

2011-08-03  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keymap.c (Fmake_composed_keymap): Move to subr.el.

2011-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
        so that it is not optimized away.

        * xdisp.c (compute_display_string_pos): Remove unused local.

2011-08-02  Eli Zaretskii  <eliz@gnu.org>

        Fix slow cursor motion and scrolling in large buffers with
        selective display, like Org Mode buffers.  (Bug#9218)

        * dispextern.h (struct bidi_it): New member disp_prop_p.

        * xdisp.c: Remove one-slot cache of display string positions.
        (compute_display_string_pos): Accept an additional argument
        DISP_PROP_P; callers changed. Scan at most 5K characters forward
        for a display string or property.  If found, set DISP_PROP_P
        non-zero.

        * bidi.c (bidi_fetch_char): Accept an additional argument
        DISP_PROP_P, and pass it to compute_display_string_pos.
        Only handle text covered by a display string if DISP_PROP_P is returned
        non-zero.  All callers of bidi_fetch_char changed.

2011-08-02  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

2010-12-03  Don March  <don@ohspite.net>

        * keymap.c (Fdefine_key): Fix non-prefix key error message when
        last character M-[char] is translated to ESC [char] (bug#7541).

2011-08-02  Kenichi Handa  <handa@m17n.org>

        * lisp.h (uniprop_table): Extern it.

        * chartab.c (uniprop_table): Make it non-static.

2011-08-01  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (forward_to_next_line_start): Accept additional argument
        BIDI_IT_PREV, and store into it the state of the bidi iterator had
        on the newline.
        (reseat_at_next_visible_line_start): Use the bidi iterator state
        returned by forward_to_next_line_start to restore the state of
        it->bidi_it after backing up to previous newline.  (Bug#9212)

2011-07-30  Andreas Schwab  <schwab@linux-m68k.org>

        * regex.c (re_comp): Protoize.
        (re_exec): Fix return type.
        (regexec): Fix type of `ret'.  (Bug#9203)

2011-07-29  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
        This is needed if max-image-size is a floating-point number.

2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>

        * print.c (print_object): Print empty symbol as ##.

        * lread.c (read1): Read ## as empty symbol.

2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>

        * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
        setting frame foreground color (Bug#9175).
        (x_set_background_color): Likewise.

        * nsmenu.m (-setText): Size tooltip dimensions precisely to
        contents (Bug#9176).
        (EmacsTooltip -init): Remove bezels and add shadows to
        tooltip windows.

        * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
        or scroll bar (Bug#8470).

        * nsfont.m (nsfont_open): Remove assignment to voffset and
        unnecessary vars hshink, expand, hd, full_height, min_height.
        (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).

        * nsterm.h (nsfont_info): Remove voffset field.

2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>

        Implement strike-through and overline on NextStep (Bug#8863).

        * nsfont.m (nsfont_open): Use underline position provided by font,
        instead of hard-coded value of 2.
        (nsfont_draw): Call ns_draw_text_decoration instead.

        * nsterm.h: Add declaration for ns_draw_text_decoration.

        * nsterm.m (ns_draw_text_decoration): New function for drawing
        underline, overline, and strike-through.
        (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
        ns_draw_text_decoration.  Change treatment of cursor drawing to
        accomodate underlining, etc.

2011-07-28  Eli Zaretskii  <eliz@gnu.org>

        * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
        default.

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
        Without this fix, if a signal arrives just after memory fills up,
        'malloc' might be invoked reentrantly.

        * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
        In other words, assume that every image size is allowed, on non-X
        hosts.  This assumption is probably wrong, but it lets Emacs compile.

2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>

        * regex.c (re_iswctype): Convert return values to boolean.

2011-07-28  Eli Zaretskii  <eliz@fencepost.gnu.org>

        * xdisp.c (compute_display_string_pos): Don't use cached display
        string position if the buffer had its restriction changed.
        (Bug#9184)

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>

        Integer signedness and overflow and related fixes.  (Bug#9079)

        * bidi.c: Integer size and overflow fixes.
        (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
        (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
        (bidi_cache_find_level_change, bidi_cache_ensure_space)
        (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
        (bidi_find_other_level_edge):
        Use ptrdiff_t instead of EMACS_INT where either will do.
        This works better on 32-bit hosts configured --with-wide-int.
        (bidi_cache_ensure_space): Check for size-calculation overflow.
        Use % rather than repeated addition, for better worst-case speed.
        Don't set bidi_cache_size until after xrealloc returns, because it
        might not return.
        (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
        (bidi_cache_ensure_space): Also check that the bidi cache size
        does not exceed that of the largest Lisp string or buffer.  See Eli
        Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.

        * alloc.c (__malloc_size_t): Remove.
        All uses replaced by size_t.  See Andreas Schwab's note
        <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.

        * image.c: Improve checking for integer overflow.
        (check_image_size): Assume that f is nonnull, since
        it is always nonnull in practice.  This is one less thing to
        worry about when checking for integer overflow later.
        (x_check_image_size): New function, which checks for integer
        overflow issues inside X.
        (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
        This removes the need for a memory_full check.
        (xbm_image_p): Rewrite to avoid integer multiplication overflow.
        (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
        (xbm_read_bitmap_data): Change locals back to 'int', since
        their values must fit in 'int'.
        (xpm_load_image, png_load, tiff_load):
        Invoke x_create_x_image_and_pixmap earlier,
        to avoid much needless work if the image is too large.
        (tiff_load): Treat overly large images as if
        x_create_x_image_and_pixmap failed, not as malloc failures.
        (gs_load): Use x_check_image_size.

        * gtkutil.c: Omit integer casts.
        (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
        (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.

        * image.c (png_load): Don't assume height * row_bytes fits in 'int'.

        * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
        Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
        would wrongly return t on a 64-bit host.

        * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
        The plain *_OVERFLOW macros run afoul of GCC bug 49705
        <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
        and therefore cause GCC to emit a bogus diagnostic in some cases.

        * image.c: Integer signedness and overflow and related fixes.
        This is not an exhaustive set of fixes, but it's time to
        record what I've got.
        (lookup_pixel_color, check_image_size): Remove redundant decls.
        (check_image_size): Don't assume that arbitrary EMACS_INT values
        fit in 'int', or that arbitrary 'double' values fit in 'int'.
        (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
        (tiff_load, imagemagick_load_image):
        Check for overflow in size calculations.
        (x_create_x_image_and_pixmap): Remove unnecessary test for
        xmalloc returning NULL; that can't happen.
        (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
        (xpm_color_bucket): Use better integer hashing function.
        (xpm_cache_color): Don't possibly over-allocate memory.
        (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
        (gif_memory_source):
        Use ptrdiff_t, not int or size_t, to record sizes.
        (png_load): Don't assume values greater than 2**31 fit in 'int'.
        (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
        either works, as we prefer signed integers.
        (tiff_read_from_memory, tiff_write_from_memory):
        Return tsize_t, not size_t, since that's what the TIFF API wants.
        (tiff_read_from_memory): Don't fail simply because the read would
        go past EOF; instead, return a short read.
        (tiff_load): Omit no-longer-needed casts.
        (Fimagemagick_types): Don't assume size fits into 'int'.

        Improve hashing quality when configured --with-wide-int.
        * fns.c (hash_string): New function, taken from sxhash_string.
        Do not discard information about ASCII character case; this
        discarding is no longer needed.
        (sxhash-string): Use it.  Change sig to match it.  Caller changed.
        * lisp.h: Declare it.
        * lread.c (hash_string): Remove, since we now use fns.c's version.
        The fns.c version returns a wider integer if --with-wide-int is
        specified, so this should help the quality of the hashing a bit.

        * emacs.c: Integer overflow minor fix.
        (heap_bss_diff): Now uprintmax_t, not unsigned long.  All used changed.
        Define only if GNU_LINUX.
        (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.

        * dispnew.c: Integer signedness and overflow fixes.
        Remove unnecessary forward decls, that were a maintenance hassle.
        (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
        All uses changed.
        (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
        (scrolling_window): Use ptrdiff_t, not int, for byte count.
        (prepare_desired_row, line_draw_cost):
        Use int, not unsigned, where either works.
        (save_current_matrix, restore_current_matrix):
        Use ptrdiff_t, not size_t, where either works.
        (init_display): Check for overflow more accurately, and without
        relying on undefined behavior.

        * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
        Remove, replacing with the new symbols in lisp.h.  All uses changed.
        * fileio.c (make_temp_name):
        * filelock.c (lock_file_1, lock_file):
        * xdisp.c (message_dolog):
        Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
        Use pMd etc. instead.
        * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
        replacing the pWIDE etc. symbols removed from editfns.c.

        * keyboard.h (num_input_events): Now uintmax_t.
        This is (very slightly) less likely to mess up due to wraparound.
        All uses changed.

        * buffer.c: Integer signedness fixes.
        (alloc_buffer_text, enlarge_buffer_text):
        Use ptrdiff_t rather than size_t when either will do, as we prefer
        signed integers.

        * alloc.c: Integer signedness and overflow fixes.
        Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
        (__malloc_size_t): Default to size_t, not to int.
        (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
        (Fgarbage_collect, mark_object_loop_halt, mark_object):
        Prefer ptrdiff_t to size_t when either would do, as we prefer
        signed integers.
        (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
        (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
        Now const.  Initialize with values that are in range even if char
        is signed.
        (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
        (xmalloc_put_size, xmalloc_get_size): New functions.  All uses changed.
        These functions do the right thing with sizes > 2**32.
        (check_depth): Now ptrdiff_t, not int.
        (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
        Adjust to new way of storing sizes.  Check for size overflow bugs
        in rest of code.
        (STRING_BYTES_MAX): Adjust to new overheads.  The old code was
        slightly wrong anyway, as it missed one instance of
        XMALLOC_OVERRUN_CHECK_OVERHEAD.
        (refill_memory_reserve): Omit needless cast to size_t.
        (mark_object_loop_halt): Mark as externally visible.

        * xselect.c: Integer signedness and overflow fixes.
        (Fx_register_dnd_atom, x_handle_dnd_message):
        Use ptrdiff_t, not size_t, since we prefer signed.
        (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
        * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
        x_dnd_atoms_size and x_dnd_atoms_length.

        * doprnt.c: Prefer signed to unsigned when either works.
        * eval.c (verror):
        * doprnt.c (doprnt):
        * lisp.h (doprnt):
        * xdisp.c (vmessage):
        Use ptrdiff_t, not size_t, when using or implementing doprnt,
        since the sizes cannot exceed ptrdiff_t bounds anyway, and we
        prefer signed arithmetic to avoid comparison confusion.
        * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
        but is a bit tricky.

        Assume freestanding C89 headers, string.h, stdlib.h.
        * data.c, doprnt.c, floatfns.c, print.c:
        Include float.h unconditionally.
        * gmalloc.c: Assume C89-at-least behavior for preprocessor,
        limits.h, stddef.h, string.h.  Use memset instead of 'flood'.
        * regex.c: Likewise for stddef.h, string.h.
        (ISASCII): Remove; can assume it returns 1 now.  All uses removed.
        * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
        * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
        (STDC_HEADERS): Remove obsolete defines.
        * sysdep.c: Include limits.h unconditionally.

        Assume support for memcmp, memcpy, memmove, memset.
        * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
        * regex.c (memcmp, memcpy):
        Remove; we assume C89 now.

        * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
        (__malloc_safe_bcopy): Remove; no longer needed.

        * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
        Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
        well either way, and we prefer signed to unsigned.

2011-07-27  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
        closes the connection while we're reading (bug#9182).

2011-07-25  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
        are specified (Bug#9168).

2011-07-25  Paul Eggert  <eggert@cs.ucla.edu>

        * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
        Found by GCC static checking and --with-wide-int on a 32-bit host.

2011-07-25  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (compute_display_string_pos): Fix logic of caching
        previous display string position.  Initialize cached_prev_pos to
        -1.  Fixes slow-down at the beginning of a buffer.

2011-07-24  Eli Zaretskii  <eliz@gnu.org>

        * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
        for attrs[LFACE_FONTSET_INDEX].

2011-07-23  Paul Eggert  <eggert@cs.ucla.edu>

        * xml.c (parse_region): Remove unused local
        that was recently introduced.

2011-07-23  Eli Zaretskii  <eliz@gnu.org>

        * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
        2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.

        * xdisp.c (move_it_in_display_line_to): Record the best matching
        position for TO_CHARPOS while scanning the line, and restore it on
        exit if none of the characters scanned was an exact match.
        Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
        when exact match is impossible due to invisible text, and the
        lines are truncated.

2011-07-23  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
        for OSX >= 10.7.

2011-07-22  Eli Zaretskii  <eliz@gnu.org>

        Fix a significant slow-down of cursor motion with C-n, C-p,
        C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
        auto-repeat under bidi redisplay in fontified buffers.
        * xdisp.c (compute_stop_pos_backwards): New function.
        (next_element_from_buffer): Call compute_stop_pos_backwards to
        find a suitable prev_stop when we find ourselves before
        base_level_stop.
        (reseat): Don't look for prev_stop, as that could mean a very long
        run.
        <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
        <cached_disp_overlay_modiff>: Cache for last found display string
        position.
        (compute_display_string_pos): Return the cached position if asked
        about the same buffer in the same area of character positions, and
        the buffer wasn't changed since the time the display string
        position was cached.

2011-07-22  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
        is an integer, which is important for empty lines.  (Bug#9149)

2011-07-22  Chong Yidong  <cyd@stupidchicken.com>

        * frame.c (Fmodify_frame_parameters): In tty case, update the
        default face if necessary (Bug#4238).

2011-07-21  Chong Yidong  <cyd@stupidchicken.com>

        * editfns.c (Fstring_to_char): No need to explain what a character
        is in the docstring (Bug#6576).

2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * xml.c (parse_region): Make sure we always return a tree.

2011-07-20  HAMANO Kiyoto  <khiker.mail@gmail.com>

        * xml.c (parse_region): If a document contains only comments,
        return that, too.

2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * xml.c (make_dom): Return comments, too.

2011-07-19  Paul Eggert  <eggert@cs.ucla.edu>

        Port to OpenBSD.
        See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
        and the surrounding thread.
        * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
        rather than fgets, and retry after EINTR.  Otherwise, 'emacs
        --batch -f byte-compile-file' fails on OpenBSD if an inactivity
        timer goes off.
        * s/openbsd.h (BROKEN_SIGIO): Define.
        * unexelf.c (unexec) [__OpenBSD__]:
        Don't update the .mdebug section of the Alpha COFF symbol table.

2011-07-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
        (bug#8460).

2011-07-18  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
        This fixes some race conditions on the permissions of any newly
        created file.

        * alloc.c (valid_pointer_p): Use pipe, not open.
        This fixes some permissions issues when debugging.

        * fileio.c (Fcopy_file): Adjust mode if fchown fails.  (Bug#9002)
        If fchown fails to set both uid and gid, try to set just gid,
        as that is sometimes allowed.  Adjust the file's mode to eliminate
        setuid or setgid bits that are inappropriate if fchown fails.

2011-07-18  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

2011-07-17  Andreas Schwab  <schwab@linux-m68k.org>

        * lread.c (read_integer): Unread even EOF character.
        (read1): Likewise.  Properly record start position of symbol.

        * lread.c (read1): Read `#:' as empty uninterned symbol if no
        symbol character follows.

2011-07-17  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fcopy_file): Pacify gcc re fchown.  (Bug#9002)
        This works around a problem with the previous change to Fcopy_file.
        Recent glibc declares fchown with __attribute__((warn_unused_result)),
        and without this change, GCC might complain about discarding
        fchown's return value.

2011-07-16  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

2011-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        * fileio.c (Fcopy_file): Don't diagnose fchown failures.  (Bug#9002)

2011-07-16  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
        it's used from the C level.

        * process.c: Use the same condition for POLL_FOR_INPUT in both
        keyboard.c and process.c (bug#1858).

2011-07-09  Lawrence Mitchell  <wence@gmx.li>

        * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
        (Fgnutls_boot): Use it.

2011-07-15  Andreas Schwab  <schwab@linux-m68k.org>

        * doc.c (Fsubstitute_command_keys): Revert last change.

2011-07-15  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * doc.c (Fsubstitute_command_keys): Clarify that \= really only
        quotes the next character, and doesn't affect other longer
        sequences (bug#8935).

        * lread.c (syms_of_lread): Clarify that is isn't only
        `eval-buffer' and `eval-defun' that's affected by
        `lexical-binding' (bug#8460).

2011-07-15  Eli Zaretskii  <eliz@gnu.org>

        bidi redisplay when a line includes both an image and is
        truncated.

2011-07-14  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.
        * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
        (elsz): Now a signed constant, not a size_t var.  We prefer signed
        types to unsigned, to avoid integer comparison confusion.  Without
        this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
        "cannot optimize loop, the loop counter may overflow", a symptom
        of the confusion.
        * indent.c (Fvertical_motion): Mark locals as initialized.
        * xdisp.c (reseat_to_string): Fix pointer signedness issue.

2011-07-14  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * search.c (Fre_search_backward): Mention `case-fold-search' in
        all the re_search_* functions (bug#8138).

        * keyboard.c (Fopen_dribble_file): Document when the file is
        closed (bug#8056).

        buffer position was specified.  Initialize paragraph_embedding to
        L2R.
        (reseat_to_string): Initialize the bidi iterator.
        (display_string): If we need to ignore text properties of
        LISP_STRING, set IT->stop_charpos to IT->end_charpos.  (The
        original value of -1 will not work with bidi.)
        (compute_display_string_pos): First arg is now struct
        `text_pos *'; all callers changed.  Support display properties on
        Lisp strings.

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

        (next_element_from_buffer): Add xassert's for correspondence
        between IT's object being iterated and it->bidi_it.string
        structure.
        (face_before_or_after_it_pos): Support bidi iteration.

        character that is not the first one in the visual order.
        (get_visually_first_element): New function, refactored from common
        parts of next_element_from_buffer, next_element_from_string, and
        next_element_from_c_string.
        (tool_bar_lines_needed, redisplay_tool_bar)
        (display_menu_bar): Force left-to-right direction.  Add a FIXME
        comment for making that be controlled by a user option.

        iterator for displaying display or overlay strings.
        (forward_to_next_line_start): Don't use the shortcut if
        bidi-iterating.
        (back_to_previous_visible_line_start): If handle_display_prop
        pushed the iterator stack, restore the internal state of the bidi
        iterator by calling bidi_pop_it same number of times.
        (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
        and we are bidi-iterating, don't decrement the iterator position;
        instead, set the first_elt flag in the bidi iterator, to produce
        the same effect.

        popping after iteration over a string that came from a display
        property.  Fix a typo in popping stretch info.  Add an assertion
        for verifying that the iterator position is in sync with the bidi
        iterator.
        (handle_single_display_spec, get_overlay_strings_1)
        (push_display_prop): Fix initialization of paragraph direction for
        string when that of the parent object is not yet determined.

        (move_it_in_display_line_to): If iterator ended up at
        EOL, but we never saw any buffer positions smaller than
        to_charpos, return MOVE_POS_MATCH_OR_ZV.  Fixes vertical cursor
        motion in bidi-reordered lines.
        (move_it_in_display_line_to): Record prev_method and prev_pos
        immediately before the call to set_iterator_to_next.  Fixes cursor

        * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
        The old code sometimes used this field without initializing it.

        * alloc.c (gc_sweep): Don't read past end of array.
        In theory, the old code could also have corrupted Emacs internals,
        though it'd be very unlikely.

        Use pthread_sigmask, not sigprocmask (Bug#9010).
        sigprocmask is portable only for single-threaded applications, and
        Emacs can be multi-threaded when it uses GTK.

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

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

2011-07-04  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * buffer.c (Foverlay_put): Say what the return value is

        unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.  All callers changed.
        Also (re)move comments that are misplaced or no longer relevant.

        (emacs_settings_set_property, emacs_settings_class_init)
        (emacs_settings_init, gsettings_obj): Remove.
        (something_changedCB): New function for HAVE_GSETTINGS.
        (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
        with value as argument.
        (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
        g_settings_new (Bug#8967).  Do not create gsettings_obj.

2011-07-01  Paul Eggert  <eggert@cs.ucla.edu>

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

2011-06-30  Jan Djärv  <jan.h.d@swipnet.se>

        (init_gsettings): New function.
        (xsettings_initialize): Call init_gsettings.
        (syms_of_xsettings): Initialize gsettings_client, gsettings_obj
        to NULL.

        * Makefile.in (SETTINGS_CFLAGS, SETTINGS_LIBS): Rename from

        (emacs_fixed_new): Set priv->f to argument.
        (emacs_fixed_get_preferred_width)
        (emacs_fixed_get_preferred_height): Use min_width/height from
        frames size_hint to set minimum and natural (Bug#8919).
        (XSetWMSizeHints, XSetWMNormalHints): Override these functions
        and use min_width/height from frames size_hint to set
        min_width/height (Bug#8919).

        * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
        (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

2011-06-26  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
        bidi_at_paragraph_end, since fast_looking_at doesn't like to be

        Integer and buffer overflow fixes (Bug#8873).

        * print.c (printchar, strout): Check for string overflow.
        (PRINTPREPARE, printchar, strout):
        Don't set size unless allocation succeeds.

        * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
        for sizes.  Check for string overflow more accurately.
        Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.

        * macros.c: Integer and buffer overflow fixes.
        * keyboard.h (struct keyboard.kbd_macro_bufsize):
        * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

        * lread.c: Integer overflow fixes.
        (read_integer): Radix is now EMACS_INT, not int,
        to improve quality of diagnostics for out-of-range radices.
        Calculate buffer size correctly for out-of-range radices.
        (read1): Check for integer overflow in radices, and in
        read-circle numbers.
        (read_escape): Avoid int overflow.
        (Fload, openp, read_buffer_size, read1)
        (substitute_object_recurse, read_vector, read_list, map_obarray):
        Use ptrdiff_t, not int, for sizes.
        (read1): Use EMACS_INT, not int, for sizes.
        Check for size overflow.

        * image.c (cache_image): Check for size arithmetic overflow.

        * lread.c: Integer overflow issues.
        (saved_doc_string_size, saved_doc_string_length)

2011-06-22  Leo Liu  <sdl.web@gmail.com>

        * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
        Move to minibuffer.el.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

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

        (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
        Now static.
        (debug_method_add): Use va_list and vsprintf rather than relying
        on undefined behavior with wrong number of arguments.
        (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
        Don't assume ptrdiff_t and EMACS_INT are the same width as int.
        In this code, it's OK to assume C99 behavior for ptrdiff_t formats
        since we're not interested in debugging glyphs with old libraries.
        * xfaces.c (cache_face): Move debugging code earlier; this pacifies
        GCC 4.6.0's static checking.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c (message_log_check_duplicate): Return intmax_t,
        not unsigned long, as we prefer signed integers.  All callers changed.
        Detect integer overflow in repeat count.
        (message_dolog): Don't assume print length fits in 39 bytes.
        (display_mode_element): Don't assume strlen fits in int.

        Reformulate so as not to need the command string.
        Invoke gzip -cd rather than gunzip, as it's more portable.
        (lock_info_type, lock_file_1, lock_file):
        Don't assume pid_t and time_t fit in unsigned long.
        (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
        (current_lock_owner): Prefer signed type for sizes.
        Use memcpy, not strncpy, where memcpy is what is really wanted.
        Don't assume (via atoi) that time_t and pid_t fit in int.
        Check for time_t and/or pid_t out of range, e.g., via a network share.
        Don't alloca where an auto var works fine.

        * fileio.c: Fix some integer overflow issues.

        * buffer.c (init_buffer): Don't assume string length fits in 'int'.

        * lread.c (invalid_syntax): Omit length argument.
        All uses changed.  This doesn't fix a bug, but it simplifies the
        code away from its former Hollerith-constant appearance, and it's
        one less 'int' to worry about when looking at integer-overflow issues.
        (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.

        * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
        This didn't break anything, but it didn't help either.
        It's confusing to put a bogus integer in a place where the actual
        value does not matter.
        (LIST_END_P): Remove unused macro and its bogus comment.
        (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.

        * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
        This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
        implementation.
        (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
        We prefer signed types, and the value cannot exceed the EMACS_INT
        range anyway (because otherwise the length would not be representable).
        (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
        not EMACS_UINT and EMACS_INT, when converting pointer to integer.
        This avoids a GCC warning when WIDE_EMACS_INT.

        * indent.c (sane_tab_width): New function.
        (current_column, scan_for_column, Findent_to, position_indentation)
        (compute_motion): Use it.  This is just for clarity.
        (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

        * image.c (xbm_image_p): Don't assume stated width, height fit in int.

        * lisp.h (lint_assume): New macro.
        * composite.c (composition_gstring_put_cache):
        * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.

        * editfns.c, insdel.c:
        Omit unnecessary forward decls, to simplify future changes.

        * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.

        * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.

        * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
        Use much-faster test for byte-length change.
        Don't assume string byte-length fits in 'int'.
        Check that character arg fits in 'int'.
        (mapcar1): Declare byte as byte, for clarity.

        * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.

        * fns.c (concat): Catch string overflow earlier.
        Do not rely on integer wraparound.

        * dispextern.h (struct it.overlay_strings_charpos)
        (struct it.selective): Now EMACS_INT, not int.
        * xdisp.c (forward_to_next_line_start)
        (back_to_previous_visible_line_start)
        (reseat_at_next_visible_line_start, next_element_from_buffer):
        Don't arbitrarily truncate the value of 'selective' to int.

        * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.

        * composite.c: Don't truncate sizes to 'int'.
        (composition_gstring_p, composition_reseat_it)
        (composition_adjust_point): Use EMACS_INT, not int.
        (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
        not EMACS_UINT, for indexes.

        * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.

        * buffer.c: Include <verify.h>.
        (struct sortvec.priority, struct sortstr.priority):
        Now EMACS_INT, not int.
        (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
        (struct sortstr.size, record_overlay_string)
        (struct sortstrlist.size, struct sortlist.used):
        Don't truncate size to int.
        (record_overlay_string): Check for size-calculation overflow.
        (init_buffer_once): Check at compile-time, not run-time.

2011-06-22  Jim Meyering  <meyering@redhat.com>

        Don't leak an XBM-image-sized buffer
        * image.c (xbm_load): Free the image buffer after using it.

2011-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Sun C.
        * composite.c (find_automatic_composition): Omit needless 'return 0;'
        that Sun C diagnosed.
        * fns.c (secure_hash): Fix pointer signedness issue.
        * intervals.c (static_offset_intervals): New function.
        (offset_intervals): Use it.

2011-06-21  Leo Liu  <sdl.web@gmail.com>

        * deps.mk (fns.o):
        * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
        sha512.h.

        * fns.c (secure_hash): Rename from crypto_hash_function and change
        the first arg to accept symbols.
        (Fsecure_hash): New primitive.
        (syms_of_fns): New symbols.

2011-06-20  Deniz Dogan  <deniz@dogan.se>

        * process.c (Fset_process_buffer): Clarify return value in
        docstring.

2011-06-18  Chong Yidong  <cyd@stupidchicken.com>

        * dispnew.c (add_window_display_history): Use BVAR.

        * xdisp.c (debug_method_add): Use BVAR.
        (check_window_end, dump_glyph_matrix, dump_glyph)
        (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.

        * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
        Likewise.

        * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
        check till after the cache is created in init_frame_faces.

2011-06-17  Stefan Monnier  <monnier@iro.umontreal.ca>

        * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.

2011-06-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
        Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
        hosts with pre-C99 libraries, because pD is wrongly defined to "t".

        Improve buffer-overflow checking (Bug#8873).
        * fileio.c (Finsert_file_contents):
        * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
        Remove the old (too-loose) buffer overflow checks.
        They weren't needed, since make_gap checks for buffer overflow.
        * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
        The old code merely checked for Emacs fixnum overflow, and relied
        on undefined (wraparound) behavior.  The new code avoids undefined
        behavior, and also checks for ptrdiff_t and/or size_t overflow.

        * editfns.c (Finsert_char): Don't dump core with very negative counts.
        Tune.  Don't use wider integers than needed.  Don't use alloca.
        Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.

        * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.

        * insdel.c, lisp.h (buffer_overflow): New function.
        (insert_from_buffer_1, replace_range, replace_range_2):
        * insdel.c (make_gap_larger):
        * editfns.c (Finsert_char):
        * fileio.c (Finsert_file_contents): Use it, to normalize wording.

        * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.

2011-06-15  Paul Eggert  <eggert@cs.ucla.edu>

        Integer overflow and signedness fixes (Bug#8873).

        * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
        (GET_CCL_RANGE, IN_INT_RANGE): Use it.

        * fileio.c: Don't assume EMACS_INT fits in off_t.
        (emacs_lseek): New static function.
        (Finsert_file_contents, Fwrite_region): Use it.
        Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

        * fns.c (Fload_average): Don't assume 100 * load average fits in int.

        * fns.c: Don't overflow int when computing a list length.
        * fns.c (QUIT_COUNT_HEURISTIC): New constant.
        (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
        truncation on 64-bit hosts.  Check for QUIT every
        QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
        faster and is responsive enough.
        (Flength): Report an error instead of overflowing an integer.
        (Fsafe_length): Return a float if the value is not representable
        as a fixnum.  This shouldn't happen except in contrived situations.
        (Fnthcdr, Fsort): Don't assume list length fits in int.
        (Fcopy_sequence): Don't assume vector length fits in int.

        * alloc.c: Check that resized vectors' lengths fit in fixnums.
        (header_size, word_size): New constants.
        (allocate_vectorlike): Don't check size overflow here.
        (allocate_vector): Check it here instead, since this is the only
        caller of allocate_vectorlike that could cause overflow.
        Check that the new vector's length is representable as a fixnum.

        * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
        The previous code was bogus.  For example, next_almost_prime (32)
        returned 39, which is undesirable as it is a multiple of 3; and
        next_almost_prime (24) returned 25, which is a multiple of 5 so
        why was the code bothering to check for multiples of 7?

        * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

        * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

        Variadic C functions now count arguments with ptrdiff_t.
        This partly undoes my 2011-03-30 change, which replaced int with size_t.
        Back then I didn't know that the Emacs coding style prefers signed int.
        Also, in the meantime I found a few more instances where arguments
        were being counted with int, which may truncate counts on 64-bit
        machines, or EMACS_INT, which may be unnecessarily wide.
        * lisp.h (struct Lisp_Subr.function.aMANY)
        (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
        Arg counts are now ptrdiff_t, not size_t.
        All variadic functions and their callers changed accordingly.
        (struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
        * bytecode.c (exec_byte_code): Check maxdepth for overflow,
        to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
        * callint.c (Fcall_interactively): Check arg count for overflow,
        to avoid potential buffer overrun.  Use signed char, not 'int',
        for 'varies' array, so that we needn't bother to check its size
        calculation for overflow.
        * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
        * eval.c (apply_lambda):
        * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
        (struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
        (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.

        * callint.c (Fcall_interactively): Don't use index var as event count.

        * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
        * mem-limits.h (SIZE): Remove; no longer used.

        * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.

        Remove unnecessary casts.
        * xterm.c (x_term_init):
        * xfns.c (x_set_border_pixel):
        * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
        These aren't needed now that we assume ANSI C.

        * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
        It's more likely to cause problems (due to unsigned overflow)
        than to cure them.

        * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

        * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

        * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

        * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

        * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

        * lread.c (Fload): Don't compare a possibly-garbage time_t value.

        GLYPH_CODE_FACE returns EMACS_INT, not int.
        * dispextern.h (merge_faces):
        * xfaces.c (merge_faces):
        * xdisp.c (get_next_display_element, next_element_from_display_vector):
        Don't assume EMACS_INT fits in int.

        * character.h (CHAR_VALID_P): Remove unused parameter.
        * fontset.c, lisp.h, xdisp.c: All uses changed.

        * editfns.c (Ftranslate_region_internal): Omit redundant test.

        * fns.c (concat): Minor tuning based on overflow analysis.
        This doesn't fix any bugs.  Use int to hold character, instead
        of constantly refetching from Emacs object.  Use XFASTINT, not
        XINT, for value known to be a character.  Don't bother comparing
        a single byte to 0400, as it's always less.

        * floatfns.c (Fexpt):
        * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

        * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
        for characters.

        * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

        * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
        Without this fix, on a 64-bit host (aset S 0 4294967386) would
        incorrectly succeed when S was a string, because 4294967386 was
        truncated before it was used.

        * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
        Otherwise, an out-of-range integer could cause undefined behavior
        on a 64-bit host.

        * composite.c: Use int, not EMACS_INT, for characters.
        (fill_gstring_body, composition_compute_stop_pos): Use int, not
        EMACS_INT, for values that are known to be in character range.
        This doesn't fix any bugs but is the usual style inside Emacs and
        may generate better code on 32-bit machines.

        Make sure a 64-bit char is never passed to ENCODE_CHAR.
        This is for reasons similar to the recent CHAR_STRING fix.
        * charset.c (Fencode_char): Check that character arg is actually
        a character.  Pass an int to ENCODE_CHAR.
        * charset.h (ENCODE_CHAR): Verify that the character argument is no
        wider than 'int', as a compile-time check to prevent future regressions
        in this area.

        * character.c (char_string): Remove unnecessary casts.

        Make sure a 64-bit char is never passed to CHAR_STRING.
        Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
        by silently ignoring the top 32 bits, allowing some values
        that were far too large to be valid characters.
        * character.h: Include <verify.h>.
        (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
        arguments are no wider than unsigned, as a compile-time check
        to prevent future regressions in this area.
        * data.c (Faset):
        * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
        (Fsubst_char_in_region):
        * fns.c (concat):
        * xdisp.c (decode_mode_spec_coding):
        Adjust to CHAR_STRING's new requirement.
        * editfns.c (Finsert_char, Fsubst_char_in_region):
        * fns.c (concat): Check that character args are actually
        characters.  Without this test, these functions did the wrong
        thing with wildly out-of-range values on 64-bit hosts.

        Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
        These casts should not be needed on 32-bit hosts, either.
        * keyboard.c (read_char):
        * lread.c (Fload): Remove casts to unsigned.

        * lisp.h (UNSIGNED_CMP): New macro.
        This fixes comparison bugs on 64-bit hosts.
        (ASCII_CHAR_P): Use it.
        * casefiddle.c (casify_object):
        * character.h (ASCII_BYTE_P, CHAR_VALID_P)
        (SINGLE_BYTE_CHAR_P, CHAR_STRING):
        * composite.h (COMPOSITION_ENCODE_RULE_VALID):
        * dispextern.h (FACE_FROM_ID):
        * keyboard.c (read_char): Use UNSIGNED_CMP.

        * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
        not to EMACS_INT, to avoid GCC warning.

        * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.

        * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
        The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
        isn't needed on 32-bit machines.

        * buffer.c (Fgenerate_new_buffer_name):
        Use EMACS_INT for count, not int.
        (advance_to_char_boundary): Return EMACS_INT, not int.

        * data.c (Qcompiled_function): Now static.

        * window.c (window_body_lines): Now static.

        * image.c (gif_load): Rename local to avoid shadowing.

        * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
        (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
        * alloc.c (make_save_value): Integer argument is now of type
        ptrdiff_t, not int.
        (mark_object): Use ptrdiff_t, not int.
        * lisp.h (pD): New macro.
        * print.c (print_object): Use it.

        * alloc.c: Use EMACS_INT, not int, to count objects.
        (total_conses, total_markers, total_symbols, total_vector_size)
        (total_free_conses, total_free_markers, total_free_symbols)
        (total_free_floats, total_floats, total_free_intervals)
        (total_intervals, total_strings, total_free_strings):
        Now EMACS_INT, not int.  All uses changed.
        (Fgarbage_collect): Compute overall total using a double, so that
        integer overflow is less likely to be a problem.  Check for overflow
        when converting back to an integer.
        (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
        (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
        These were 'int' variables that could overflow on 64-bit hosts;
        they were never used, so remove them instead of repairing them.
        (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
        (inhibit_garbage_collection): Set gc_cons_threshold to max value.
        Previously, this ceilinged at INT_MAX, but that doesn't work on
        64-bit machines.
        (allocate_pseudovector): Don't use EMACS_INT when int would do.

        * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
        (allocate_vectorlike): Check for ptrdiff_t overflow.
        (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
        when a (possibly-narrower) signed value would do just as well.
        We prefer using signed arithmetic, to avoid comparison confusion.

        * alloc.c: Catch some string size overflows that we were missing.
        (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
        for convenience in STRING_BYTES_MAX.
        (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
        The definition here is exact; the one in lisp.h was approximate.
        (allocate_string_data): Check for string overflow.  This catches
        some instances we weren't catching before.  Also, it catches
        size_t overflow on (unusual) hosts where SIZE_MAX <= min
        (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
        and ptrdiff_t and EMACS_INT are both 64 bits.

        * character.c, coding.c, doprnt.c, editfns.c, eval.c:
        All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
        * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.

        * character.c (string_escape_byte8): Fix nbytes/nchars typo.

        * alloc.c (Fmake_string): Check for out-of-range init.

2011-06-15  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

2011-06-14  Jan Djärv  <jan.h.d@swipnet.se>

        * xfns.c (x_set_scroll_bar_default_width): Remove argument to
        xg_get_default_scrollbar_width.

        * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
        (int_gtk_range_get_value): Move to the scroll bar part of the file.
        (style_changed_cb): Call update_theme_scrollbar_width and call
        x_set_scroll_bar_default_width and xg_frame_set_char_size for
        all frames (Bug#8505).
        (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).

        XUINT -> XFASTINT, since the integer must be nonnegative.
        (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
        since it makes no difference and we prefer signed.
        * keyboard.c (record_char): Use XUINT when all the neighbors do.
        (access_keymap): NATNUMP -> INTEGERP, since the integer must be

        only if SYSTEM_MALLOC.
        (LARGE_REQUEST): New macro, so that the issue of large requests
        is separated from the issue of spare memory.

2011-06-05  Andreas Schwab  <schwab@linux-m68k.org>

        instead of using explicit *_CHAR codes.
        (bidi_resolve_explicit, bidi_resolve_weak):
        Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
        bidirectional text is supported only in multibyte buffers.
        (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
        it to initialize the frame_window_p member of struct bidi_it.

        according to the row's direction when priming the loop that looks
        for the glyph on which to display cursor.
        (single_display_spec_intangible_p): Function deleted.
        (display_prop_intangible_p): Reimplement to call
        handle_display_spec instead of single_display_spec_intangible_p.
        Accept 3 additional arguments needed by handle_display_spec.
        This fixes incorrect cursor motion across display property with complex
        values: lists, `(when COND...)' forms, etc.

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

        last portion of handle_display_prop.
        (compute_display_string_pos): Accept additional argument

        value of a `display' property is a "replacing spec".
        (handle_single_display_spec): Accept 2 additional arguments BUFPOS
        and FRAME_WINDOW_P.  If IT is NULL, don't set up the iterator from

        the display property will replace the characters it covers.
        (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
        frame_window_p members of struct bidi_it.
        (compute_display_string_pos, compute_display_string_end):
        New functions.
        (push_it): Accept second argument POSITION, where pop_it should
        jump to continue iteration.
        (reseat_1): Initialize bidi_it.disp_pos.

        * keyboard.c (adjust_point_for_property): Adjust the call to
        display_prop_intangible_p to its new signature.

        * dispextern.h (struct bidi_it): New member frame_window_p.

        * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
        All callers changed.  (Bug#8762)

        * gnutls.c: Use Emacs's memory allocators.
        Without this change, the gnutls library would invoke malloc etc.
        directly, which causes problems on non-SYNC_INPUT hosts, and which
        runs afoul of improving memory_full behavior.  (Bug#8761)
        (fn_gnutls_global_set_mem_functions): New macro or function pointer.
        (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
        xfree instead of the default malloc, realloc, free.
        (Fgnutls_boot): No need to check for memory allocation failure,
        since xmalloc does that for us.

        Remove arbitrary limit of 2**31 entries in hash tables.  (Bug#8771)
        * category.c (hash_get_category_set):

        * lisp.h (struct Lisp_Hash_Table):
        * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
        * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'

        * alloc.c (allocate_vectorlike):
        Check for overflow in vector size calculations.
        * ccl.c (ccl_driver):
        Check for overflow when converting EMACS_INT to int.
        * fns.c, image.c: Remove unnecessary static decls that would otherwise
        need to be updated by these changes.
        * fns.c (make_hash_table, maybe_resize_hash_table):
        Check for integer overflow with large hash tables.
        (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
        Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
        (SXHASH_REDUCE): New macro.
        (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
        Use it instead of discarding useful hash info with large hash values.
        (sxhash_float): New function.
        (sxhash): Use it.  No more need for "& INTMASK" due to above changes.
        * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
        (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
        Rewrite to use FIXNUM_BITS, as this simplifies things.
        (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
        Adjust signatures to match updated version of code.
        (consing_since_gc): Now EMACS_INT, since a single hash table can
        use more than INT_MAX bytes.

        2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
        2011-04-14T06:48:41Z!eggert@cs.ucla.edu.

        * fns.c (to_uchar): Define.
        (crypto_hash_function): Use it to convert some newly-signed
        variables to unsigned, to avoid sign-extension bugs.  For example,
        without this change, (md5 "truc") would evaluate to
        45723a2aff78ff4fff7fff1114760e62 rather than the expected
        45723a2af3788c4ff17f8d1114760e62.  Reported by Antoine Levitt in

2011-05-27  Paul Eggert  <eggert@cs.ucla.edu>

        Integer overflow fixes.

        * dbusbind.c: Serial number integer overflow fixes.
        (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
        (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
        to hold a serial number that is too large for a fixnum.
        (Fdbus_method_return_internal, Fdbus_method_error_internal):
        Check for serial numbers out of range.  Decode any serial number
        that was so large that it became a float.  (Bug#8722)

        * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
        (Fdbus_call_method, Fdbus_call_method_asynchronously):
        Use XFASTINT rather than XUINT when numbers are nonnegative.
        (xd_append_arg, Fdbus_method_return_internal):
        (Fdbus_method_error_internal): Likewise.  Also, for unsigned
        arguments, check that Lisp number is nonnegative, rather than
        silently wrapping negative numbers around.  (Bug#8722)
        (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
        (Bug#8722)

        * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.

        * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.

        ccl: add integer overflow checks
        * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
        (IN_INT_RANGE): New macros.
        (ccl_driver): Use them to check for integer overflow when
        decoding a CCL program.  Many of the new checks are whether XINT (x)
        fits in int; it doesn't always, on 64-bit hosts.  The new version
        doesn't catch all possible integer overflows, but it's an
        improvement.  (Bug#8719)

        * alloc.c (make_event_array): Use XINT, not XUINT.
        There's no need for unsigned here.

        * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
        This follows up to the 2011-05-06 change that substituted uintptr_t
        for EMACS_INT.  This case wasn't caught back then.

        Rework Fformat to avoid integer overflow issues.
        * editfns.c: Include <float.h> unconditionally, as it's everywhere
        now (part of C89).  Include <verify.h>.
        (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
        (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
        (Fformat): Avoid the prepass trying to compute sizes; it was only
        approximate and thus did not catch overflow reliably.  Instead, walk
        through the format just once, formatting and computing sizes as we go,
        checking for integer overflow at every step, and allocating a larger
        buffer as needed.  Keep track separately whether the format is
        multibyte.  Keep only the most-recently calculated precision, rather
        than them all.  Record whether each argument has been converted to
        string.  Use EMACS_INT, not int, for byte and char and arg counts.
        Support field widths and precisions larger than INT_MAX.  Avoid
        sprintf's undefined behavior with conversion specifications such as %#d
        and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
        flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
        formatting out-of-range floating point numbers with int
        formats.  (Bug#8668)

        * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.

        * data.c: Avoid integer truncation in expressions involving floats.
        * data.c: Include <intprops.h>.
        (arith_driver): When there's an integer overflow in an expression
        involving floating point, convert the integers to floating point
        so that the resulting value does not suffer from catastrophic
        integer truncation.  For example, on a 64-bit host (* 4
        most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
        Do not rely on undefined behavior after integer overflow.

        merge count_size_as_multibyte, parse_str_to_multibyte
        * character.c, character.h (count_size_as_multibyte):
        Rename from parse_str_to_multibyte; all uses changed.
        Check for integer overflow.
        * insdel.c, lisp.h (count_size_as_multibyte): Remove,
        since it's now a duplicate of the other.  This is more of
        a character than a buffer op, so better that it's in character.c.
        * fns.c, print.c: Adjust to above changes.

2011-05-27  Stefan Monnier  <monnier@iro.umontreal.ca>

        * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.

        * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
        (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
        (x_clipboard_manager_save): Now static.
        (Fx_clipboard_manager_save): Rename local to avoid shadowing.

        * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
        (crypto_hash_function): Now static.
        Fix pointer signedness problems.  Avoid unnecessary initializations.

2011-05-27  Chong Yidong  <cyd@stupidchicken.com>

        * termhooks.h (Vselection_alist): Make it terminal-local.

        * terminal.c (create_terminal): Initialize it.

        * xselect.c: Support for clipboard managers.
        (Vselection_alist): Move to termhooks.h as terminal-local var.
        (LOCAL_SELECTION): New macro.
        (x_atom_to_symbol): Handle x_display_info_for_display fail case.

        (x_handle_selection_request, lisp_data_to_selection_data)
        (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
        (x_own_selection, x_get_local_selection, x_convert_selection):
        New arg, specifying work frame.  Use terminal-local Vselection_alist.
        (some_frame_on_display): Delete unused function.
        (Fx_own_selection_internal, Fx_get_selection_internal)
        (Fx_disown_selection_internal, Fx_selection_owner_p)
        (Fx_selection_exists_p): New optional frame arg.
        (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
        (x_handle_selection_clear): Don't treat other terminals with the
        same keyboard specially.  Use the terminal-local Vselection_alist.
        (x_clear_frame_selections): Use Frun_hook_with_args.

        * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.

        * xterm.h: Add support for those atoms.

2011-05-26  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
        (converted_selections, conversion_fail_tag): New global variables.
        (x_selection_request_lisp_error): Free the above.
        (x_get_local_selection): Remove unnecessary code.
        (x_reply_selection_request): Args changed; handle arbitrary array
        of converted selections stored in converted_selections.
        Separate the XChangeProperty and SelectionNotify steps.
        (x_handle_selection_request): Rewrite to handle MULTIPLE target.
        (x_convert_selection): New function.
        (x_handle_selection_event): Simplify.
        (x_get_foreign_selection): Don't ignore incoming requests while
        waiting for an answer; this will fail when we implement
        SAVE_TARGETS, and seems unnecessary anyway.
        (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
        (Vx_sent_selection_functions): Doc fix.

2011-05-26  Leo Liu  <sdl.web@gmail.com>

        * editfns.c (Ftranspose_regions): Allow empty regions.  (Bug#8699)

2011-05-25  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.

        * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
        for fringe update if it has periodic bitmap.
        (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
        and fringe_bitmap_periodic_p.

        * fringe.c (get_fringe_bitmap_data): New function.
        (draw_fringe_bitmap_1, update_window_fringes): Use it.
        (update_window_fringes): Record periodicity of fringe bitmap in glyph
        row.  Mark glyph row for fringe update if periodicity changed.

        * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
        for fringe update unless it has periodic bitmap.

2011-05-25  Kenichi Handa  <handa@m17n.org>

        * xdisp.c (get_next_display_element): Set correct it->face_id for
        a static composition.

2011-05-24  Leo Liu  <sdl.web@gmail.com>

        * deps.mk (fns.o):
        * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.

        * fns.c (crypto_hash_function, Fsha1): New function.
        (Fmd5): Use crypto_hash_function.
        (syms_of_fns): Add Ssha1.

2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * gnutls.c: Remove unused macros.
        (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
        (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
        Remove macros that are defined and never used.
        Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

2011-05-22  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
        (Fx_get_selection_internal): Minor cleanup.
        (Fx_own_selection_internal): Rename arguments for consistency with
        select.el.

2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

2011-05-22  Chong Yidong  <cyd@stupidchicken.com>

        * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.

2011-05-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * dispnew.c (scrolling_window): Don't exclude the case that the
        last enabled row in the desired matrix touches the bottom boundary.

2011-05-21  Glenn Morris  <rgm@gnu.org>

        * Makefile.in ($(etc)/DOC): Make second command line even shorter.
        (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
        and add some more files.

2011-05-20  Eli Zaretskii  <eliz@gnu.org>

        * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
        report_file_error introduced by the change from 2011-05-07.

2011-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * systime.h (Time): Define only if emacs is defined.
        This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
        where the include path doesn't have X11/X.h by default.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

2011-05-20 Kenichi Handa  <handa@m17n.org>

        * composite.c (find_automatic_composition): Fix previous change.

2011-05-20  Glenn Morris  <rgm@gnu.org>

        * lisp.mk: New file, split from Makefile.in.
        * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
        (shortlisp): Remove.
        ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.

2011-05-19  Glenn Morris  <rgm@gnu.org>

        * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
        (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
        (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
        (lisp): Set the order to that of loadup.el.
        (shortlisp): Make it a copy of $lisp.
        (SOME_MACHINE_LISP): Remove.
        ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
        Use just $shortlisp, not $SOME_MACHINE_LISP too.

2011-05-18  Kenichi Handa  <handa@m17n.org>

        * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
        (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
        (find_automatic_composition): Mostly rewrite for efficiency.

2011-05-18  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Update dependencies.

2011-05-18  Christoph Scholtes  <cschol2112@googlemail.com>

        * menu.c: Include limits.h (fixes the MS-Windows build broken by
        2011-06-18T18:49:19Z!cyd@stupidchicken.com).

2011-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some integer overflow issues, such as string length overflow.

        * insdel.c (count_size_as_multibyte): Check for string overflow.

        * character.c (lisp_string_width): Check for string overflow.
        Use EMACS_INT, not int, for string indexes and lengths; in
        particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
        the resulting string length overflows an EMACS_INT; instead,
        report a string overflow if no precision given.  When checking for
        precision exhaustion, use a check that cannot possibly have
        integer overflow.  (Bug#8675)
        * character.h (lisp_string_width): Adjust to new signature.

        * alloc.c (string_overflow): New function.
        (Fmake_string): Use it.  This doesn't change behavior, but saves
        a few bytes and will simplify future changes.
        * character.c (string_escape_byte8): Likewise.
        * lisp.h (string_overflow): New decl.

        Fixups, following up to the user-interface timestamp change.
        * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
        for UI timestamps, instead of unsigned long.
        * msdos.c (mouse_get_pos): Likewise.
        * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
        * w32gui.h (Time): Define by including "systime.h" rather than by
        declaring it ourselves.  (Bug#8664)

        * dispextern.h (struct image): Don't assume time_t <= unsigned long.
        * image.c (clear_image_cache): Likewise.

        * term.c (term_mouse_position): Don't assume time_t wraparound.

        Be more systematic about user-interface timestamps.
        Before, the code sometimes used 'Time', sometimes 'unsigned long',
        and sometimes 'EMACS_UINT', to represent these timestamps.
        This change causes it to use 'Time' uniformly, as that's what X uses.
        This makes the code easier to follow, and makes it easier to catch
        integer overflow bugs such as Bug#8664.
        * frame.c (Fmouse_position, Fmouse_pixel_position):
        Use Time, not unsigned long, for user-interface timestamps.
        * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
        (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
        * keyboard.h (last_event_timestamp): Likewise.
        * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
        * menu.h (xmenu_show): Likewise.
        * term.c (term_mouse_position): Likewise.
        * termhooks.h (struct input_event.timestamp): Likewise.
        (struct terminal.mouse_position_hook): Likewise.
        * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
        * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
        * systime.h (Time): New decl.  Pull it in from <X11/X.h> if
        HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
        what it was before.
        * menu.h, termhooks.h: Include "systime.h", for Time.

        * keyboard.c (make_lispy_event): Fix problem in integer overflow.
        Don't assume that the difference between two unsigned long values
        can fit into an integer.  At this point, we know button_down_time
        <= event->timestamp, so the difference must be nonnegative, so
        there's no need to cast the result if double-click-time is
        nonnegative, as it should be; check that it's nonnegative, just in
        case.  This bug is triggered when events are more than 2**31 ms
        apart (about 25 days).  (Bug#8664)

        * xselect.c (last_event_timestamp): Remove duplicate decl.
        (x_own_selection): Remove needless cast to unsigned long.

        * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
        that always fit in int.  Use a sentinel instead of a counter, to
        avoid a temp and to allay GCC's concerns about possible int overflow.
        * frame.h (struct frame): Use int for menu_bar_items_used
        instead of EMACS_INT, since it always fits in int.

        * menu.c (grow_menu_items): Check for int overflow.

        * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.

        * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
        Before, the code was not consistent.  These values cannot exceed
        2**31 - 1 so there's no need to make them unsigned.
        (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
        (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
        (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
        as modifiers.
        * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.

        * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
        (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
        Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
        presumably because the widths might not match.

        * window.c (size_window): Avoid needless test at loop start.

2011-05-18  Courtney Bane  <emacs-bugs-7626@cbane.org>  (tiny change)

        * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).

2011-05-12  Drew Adams  <drew.adams@oracle.com>

        * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).

2011-05-12  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
        `width' to `bar_area_x' and `bar_area_width', respectively.
        (x_scroll_run): Take account of fringe background extension.

        * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
        Rename local vars `left' and `width' to `bar_area_x' and
        `bar_area_width', respectively.
        (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
        background extension.

2011-05-10  Jim Meyering  <meyering@redhat.com>

        * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".

2011-05-10  Juanma Barranquero  <lekktu@gmail.com>

        * image.c (Finit_image_library): Return t for built-in image types,
        like pbm and xbm.  (Bug#8640)

2011-05-09  Andreas Schwab  <schwab@linux-m68k.org>

        * w32menu.c (set_frame_menubar): Fix submenu allocation.

2011-05-07  Eli Zaretskii  <eliz@gnu.org>

        * w32console.c (Fset_screen_color): Doc fix.
        (Fget_screen_color): New function.
        (syms_of_ntterm): Defsubr it.

        * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
        unlink the temporary file if Fcall_process didn't create it in the
        first place.
        (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
        child process will be redirected to a file specified with `:file'.
        Don't try to re-open tempfile in that case, and set fd[0] to -1 as
        cue to call_process_cleanup not to close that handle.

2011-05-07  Ben Key  <bkey76@gmail.com>

        * makefile.w32-in: The bootstrap-temacs rule now makes use of
        one of two shell specific rules, either bootstrap-temacs-CMD or
        bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
        to the previous implementation of the bootstrap-temacs rule.
        The bootstrap-temacs-CMD rule is similar to the previous
        implementation of the bootstrap-temacs rule except that it
        makes use of the ESC_CFLAGS variable instead of the CFLAGS
        variable.

        These changes, along with some changes to nt/configure.bat,
        nt/gmake.defs, and nt/nmake.defs, are required to extend my
        earlier fix to add support for --cflags and --ldflags options
        that include quotes so that it works whether make uses cmd or
        sh as the shell.

2011-05-06  Michael Albinus  <michael.albinus@gmx.de>

        * dbusbind.c (QCdbus_type_unix_fd): Declare static.
        (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
        is a constant.
        (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
        a string.  Handle both cases.
        (Fdbus_call_method_asynchronously, Fdbus_register_signal)
        (Fdbus_register_method): Use Qinvalid_function.

2011-05-06  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Update dependencies.
        (LISP_H): Add inttypes.h and stdin.h.
        (PROCESS_H): Add unistd.h.

2011-05-06  Eli Zaretskii  <eliz@gnu.org>

        * lread.c: Include limits.h (fixes the MS-Windows build broken by
        2011-05-06T07:13:19Z!eggert@cs.ucla.edu).

2011-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.

        * term.c (vfatal): Remove stray call to va_end.
        It's not needed and the C Standard doesn't allow it here anyway.

        Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
        * eval.c (verror): doprnt a copy of ap, not the original.  (Bug#8545)

        * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
        bytes.

        * term.c: Don't include <stdarg.h>, as <lisp.h> does that.

        * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

        * process.c (Fformat_network_address): Fix typo: args2 -> *args2.

        * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).

        * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).

        * charset.h (struct charset.code_space): Now has 15 elements, not 16.
        * charset.c (Fdefine_charset_internal): Don't initialize
        charset.code_space[15].  The value was garbage, on hosts with
        32-bit int (Bug#8600).

        * lread.c (read_integer): Be more consistent with string-to-number.
        Use string_to_number to do the actual conversion; this avoids
        rounding errors and fixes some other screwups.  Without this fix,
        for example, #x1fffffffffffffff was misread as -2305843009213693952.
        (digit_to_number): Move earlier, for benefit of read_integer.
        Return -1 if the digit is out of range for the base, -2 if it is
        not a digit in any supported base.  (Bug#8602)

        * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".

        * dispnew.c (scrolling_window): Return 1 if we scrolled,
        to match comment at start of function.  This also removes a
        GCC warning about overflow in a 32+64-bit port.

        * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

        * dbusbind.c: Do not use XPNTR on a value that may be an integer.
        Reported by Stefan Monnier in
        <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
        (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
        Use SYMBOLP-guarded XSYMBOL, not XPNTR.

        * lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
        (EMACS_UINTPTR): Likewise, with uintptr_t.

        * lisp.h: Prefer 64-bit EMACS_INT if available.
        (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
        on 32-bit hosts that have 64-bit int, so that they can access
        large files.
        However, temporarily disable this change unless the temporary
        symbol WIDE_EMACS_INT is defined.

        * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

        Prefer intptr_t/uintptr_t for integers the same widths as pointers.
        This removes an assumption that EMACS_INT and long are the same
        width as pointers.  The assumption is true for Emacs porting targets
        now, but we want to make other targets possible.
        * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
        (EMACS_INTPTR, EMACS_UINTPTR): New macros.
        In the rest of the code, change types of integers that hold casted
        pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
        replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
        (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
        (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
        No need to cast type when ORing.
        (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
        * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
        * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
        assume EMACS_INT is the same width as char *.
        * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
        (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
        Remove no-longer-needed casts.
        (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
        (xg_tool_bar_help_callback, xg_make_tool_item):
        Use EMACS_INTPTR to hold an integer
        that will be cast to void *; this can avoid a GCC warning
        if EMACS_INT is not the same width as void *.
        * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
        * xdisp.c (display_echo_area_1, resize_mini_window_1):
        (current_message_1, set_message_1):
        Use a local to convert to proper width without a cast.
        * xmenu.c (dialog_selection_callback): Likewise.

        * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
        Also, don't assume VALBITS / RAND_BITS is less than 5,
        and don't rely on undefined behavior when shifting a 1 left into
        the sign bit.
        * lisp.h (get_random): Change signature to match.

        * lread.c (hash_string): Use size_t, not int, for hash computation.
        Normally we prefer signed values; but hashing is special, because
        it's better to use unsigned division on hash table sizes so that
        the remainder is nonnegative.  Also, size_t is the natural width
        for hashing into memory.  The previous code used 'int', which doesn't
        retain enough info to hash well into very large tables.
        (oblookup, oblookup_last_bucket_number, Funintern): Likewise.

        * dbusbind.c: Don't possibly lose pointer info when converting.
        (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
        Use XPNTR rather than XHASH, so that the high-order bits of
        the pointer aren't lost when converting through void *.

        * eval.c (Fautoload): Don't double-shift a pointer.

        * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

        * gnutls.c (DEF_GNUTLS_FN):

2011-05-05  Juanma Barranquero  <lekktu@gmail.com>

        Remove unused parameter `fildes'.
        * process.c (read_process_output, send_process): Don't pass it.

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

        Fix previous change: the library cache is defined in w32.c.
        * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
        (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

        Implement dynamic loading of GnuTLS on Windows.

        (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
        (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):

        its filename in the :loaded-from property of the library id.
        (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
        Initialize and staticpro them.
        (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

        * process.c: Include lisp.h before w32.h, not after.
        (wait_reading_process_output): Call emacs_gnutls_record_check_pending
        instead of gnutls_record_check_pending.

        * callproc.c, emacs.c: Include lisp.h before w32.h, not after.

2011-05-04  Teodor Zlatanov  <tzz@lifelogs.com>

        (Fcall_process_region): Ditto.

2011-04-30  Eli Zaretskii  <eliz@gnu.org>

        * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
        rather than `XVECTOR (FOO)->size'.

        * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
        inttypes.h, as a gnulib replacement is used if it not available in
        system headers.

        * coding.c (coding_alloc_by_realloc): Error out if destination

        (decode_coding_emacs_mule): Abort if there isn't enough place in

        Improve `doprnt' and its usage.  (Bug#8545)
        * doprnt.c (doprnt): Make sure `format' is never accessed beyond
        `format_end'.  Remove support for %l as a conversion specifier.
        Don't use xrealloc.  Improve diagnostics when the %l size modifier
        is used.  Update the commentary.

        * eval.c (verror): Simplify calculation of size_t.

        * coding.c (Ffind_operation_coding_system): Fix diagnostic error
        messages.

2011-04-27  Yoshiaki Kasahara  <kasahara@nc.kyushu-u.ac.jp>  (tiny change)

        * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
        change.

2011-04-27  Paul Eggert  <eggert@cs.ucla.edu>

        * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
        This makes this file independent of the recent pseudovector change.

2011-04-26  Paul Eggert  <eggert@cs.ucla.edu>

        * keyboard.c (handle_user_signal): Fix pointer signedness problem.

        * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
        (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
        Remove unused local.
        (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.

        * lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
        GCC 4.6.0 optimizes based on type-based alias analysis.
        For example, if b is of type struct buffer * and v of type struct
        Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
        != &v->size, and therefore "v->size = 1; b->size = 2; return
        v->size;" must therefore return 1.  This assumption is incorrect
        for Emacs, since it type-puns struct Lisp_Vector * with many other
        types.  To fix this problem, this patch adds a new type struct
        vectorlike_header that documents the constraints on layout of vectors
        and pseudovectors, and helps optimizing compilers not get fooled
        by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
        XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
        * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
        the size member.
        (XSETPVECTYPE): Rewrite in terms of new macro.
        (XSETPVECTYPESIZE): New macro, specifying both type and size.
        This is a bit clearer, and further avoids the possibility of
        undesirable aliasing.
        (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
        (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
        (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
        since Lisp_Subr is a special case (no "next" field).
        (ASIZE): Now uses header.size rather than size.
        All previous uses of XVECTOR (foo)->size replaced to use this macro,
        to avoid the hassle of writing XVECTOR (foo)->header.size.
        (struct vectorlike_header): New type.
        (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
        object, to help avoid aliasing.
        (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
        (SUBRP): Likewise, since Lisp_Subr is a special case.
        * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
        (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
        (struct Lisp_Hash_Table): Combine first two members into a single
        struct vectorlike_header member.  All uses of "size" and "next" members
        changed to be "header.size" and "header.next".
        * buffer.h (struct buffer): Likewise.
        * font.h (struct font_spec, struct font_entity, struct font): Likewise.
        * frame.h (struct frame): Likewise.
        * process.h (struct Lisp_Process): Likewise.
        * termhooks.h (struct terminal): Likewise.
        * window.c (struct save_window_data, struct saved_window): Likewise.
        * window.h (struct window): Likewise.
        * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
        Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
        * buffer.c (init_buffer_once): Likewise.
        * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
        special case.
        * process.c (Fformat_network_address): Use local var for size,
        for brevity.

        * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

        Make the Lisp reader and string-to-float more consistent (Bug#8525)
        * data.c (atof): Remove decl; no longer used or needed.
        (digit_to_number): Move to lread.c.
        (Fstring_to_number): Use new string_to_number function, to be
        consistent with how the Lisp reader treats infinities and NaNs.
        Do not assume that floating-point numbers represent EMACS_INT
        without losing information; this is not true on most 64-bit hosts.
        Avoid double-rounding errors, by insisting on integers when
        parsing non-base-10 numbers, as the documentation specifies.
        * lisp.h (string_to_number): New decl, replacing ...
        (isfloat_string): Remove.
        * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
        (read1): Do not accept +. and -. as integers; this
        appears to have been a coding error.  Similarly, do not accept
        strings like +-1e0 as floating point numbers.  Do not report
        overflow for integer overflows unless the base is not 10 which
        means we have no simple and reliable way to continue.
        Break out the floating-point parsing into a new
        function string_to_number, so that Fstring_to_number parses
        floating point numbers consistently with the Lisp reader.
        (digit_to_number): Move here from data.c.  Make it static inline.
        (E_CHAR, EXP_INT): Remove, replacing with ...
        (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
        (string_to_number): New function, replacing isfloat_string.
        This function checks for valid syntax and produces the resulting
        Lisp float number too.  Rework it so that string-to-number
        no longer mishandles examples like "1.0e+".  Use strtoumax,
        so that overflow for non-base-10 numbers is reported only when
        there's no portable and simple way to convert to floating point.

        * textprop.c (set_text_properties_1): Rewrite for clarity,
        and to avoid GCC warning about integer overflow.

        * intervals.h (struct interval): Use EMACS_INT for members
        where EMACS_UINT might cause problems.  See
        <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
        (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
        * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
        All uses changed.
        (offset_intervals): Tell GCC not to worry about length overflow
        when negating a negative length.

        * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
        (overrun_check_free): Likewise.

        * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
        in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
        word size.

        * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
        (gnutls_make_error): Rename local to avoid shadowing.
        (gnutls_emacs_global_deinit): ifdef out; not used.
        (Fgnutls_boot): Use const for pointer to readonly storage.
        Comment out unused local.  Fix pointer signedness problems.

        * lread.c (openp): Don't stuff size_t into an 'int'.
        Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
        about possible signed overflow.

        * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
        (GDK_KEY_g): Don't define if already defined.
        (xg_prepare_tooltip): Avoid pointer signedness problem.
        (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.

        * process.c (Fnetwork_interface_info): Avoid left-shift undefined
        behavior with 1 << 31.  GCC 4.6.0 warns about this on 32-bit hosts.

        * xfns.c (Fx_window_property): Simplify a bit,
        to make a bit faster and to avoid GCC 4.6.0 warning.
        * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.

        * fns.c (internal_equal): Don't assume size_t fits in int.

        * alloc.c (compact_small_strings): Tighten assertion a little.

        Replace pEd with more-general pI, and fix some printf arg casts.
        * lisp.h (pI): New macro, generalizing old pEd macro to other
        conversion specifiers.  For example, use "...%"pI"d..." rather
        than "...%"pEd"...".
        (pEd): Remove.  All uses replaced with similar uses of pI.
        * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
        * alloc.c (check_pure_size): Don't overflow by converting size to int.
        * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
        * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
        * dbusbind.c (xd_append_arg): Use pI to avoid cast.
        (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
        * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
        64-bit hosts.
        (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
        * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
        * print.c (safe_debug_print, print_object): Likewise.
        (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
        to int.
        Use pI instead of if-then-else-abort.  Use %p to avoid casts,
        avoiding the 0 flag, which is not portable.
        * process.c (Fmake_network_process): Use pI to avoid cast.
        * region-cache.c (pp_cache): Likewise.
        * xdisp.c (decode_mode_spec): Likewise.
        * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
        behavior on 64-bit hosts with printf arg.
        * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
        (x_stop_queuing_selection_requests): Likewise.
        (x_get_window_property): Don't truncate byte count to an 'int'
        when tracing.

        * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
        here, since it parses constructs like leading '-' and spaces,
        which are not wanted; and it overflows with large numbers.
        Instead, simply match F[0-9]+, which is what is wanted anyway.

        * alloc.c: Remove unportable assumptions about struct layout.
        (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
        (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
        (allocate_vectorlike, make_pure_vector): Use the new macros,
        plus offsetof, to remove unportable assumptions about struct layout.
        These assumptions hold on all porting targets that I know of, but
        they are not guaranteed, they're easy to remove, and removing them
        makes further changes easier.

        * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
        This doesn't fix a bug but makes the code clearer.
        (string_overrun_cookie): Now const.  Use initializers that
        don't formally overflow signed char, to avoid warnings.
        (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
        can cause Emacs to crash when string overrun checking is enabled.
        (allocate_buffer): Don't assume sizeof (struct buffer) is a
        multiple of sizeof (EMACS_INT); it need not be, if
        alignof(EMACS_INT) < sizeof (EMACS_INT).
        (check_sblock, check_string_bytes, check_string_free_list): Protoize.

2011-04-26  Juanma Barranquero  <lekktu@gmail.com>

        (handle_user_signal): Break into debugger when debug-on-event
        matches the current signal symbol.

        * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
        "cast to pointer from integer of different size".

        Improve doprnt and its use in verror.  (Bug#8545)
        * doprnt.c (doprnt): Document the set of format control sequences
        supported by the function.  Use SAFE_ALLOCA instead of always
        using `alloca'.

        * eval.c (verror): Don't limit the buffer size at size_max-1, that
        is one byte too soon.  Don't use xrealloc; instead xfree and
        xmalloc anew.

2011-04-24  Teodor Zlatanov  <tzz@lifelogs.com>

        * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
        callbacks stage.

        * gnutls.c: Renamed global_initialized to
        gnutls_global_initialized.  Added internals for the
        :verify-hostname-error, :verify-error, and :verify-flags
        parameters of `gnutls-boot' and documented those parameters in the
        docstring.  Start callback support.
        (emacs_gnutls_handshake): Add Woe32 support.  Retry handshake
        unless a fatal error occurred.  Call gnutls_alert_send_appropriate
        on error.  Return error code.
        (emacs_gnutls_write): Call emacs_gnutls_handle_error.
        (emacs_gnutls_read): Likewise.

        them with etags.

        * makefile.w32-in (globals.h): Add a dummy recipe, to make any
        changes in globals.h immediately force recompilation.
        (TAGS): Depend on $(CURDIR)/m/intel386.h and
        $(CURDIR)/s/ms-w32.h.
        (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

        * character.c (Fchar_direction): Function deleted.
        (syms_of_character): Don't defsubr it.
        <char-direction-table>: Deleted.

2011-04-23  Eli Zaretskii  <eliz@gnu.org>

        Fix doprnt so it could be used again safely in `verror'.  (Bug#8435)
        * doprnt.c: Include limits.h.
        (SIZE_MAX): New macro.
        (doprnt): Return a size_t value.  2nd arg is now size_t.
        Many local variables are now size_t instead of int or unsigned.
        Improve overflow protection.  Support `l' modifier for integer
        conversions.  Support %l conversion.  Don't assume an EMACS_INT
        argument for integer conversions and for %c.

        * lisp.h (doprnt): Restore prototype.

        * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

        when breaking from the loop.

        * xdisp.c (vmessage): Call doprnt instead of vsnprintf.

        * callint.c (Fcall_interactively): When displaying error message
        about invalid control letter, pass the character's codepoint, not
        a pointer to its multibyte form.  Improve display of the character
        in octal and display also its hex code.

        * character.c (char_string): Use %x to display the (unsigned)
        codepoint of an invalid character, to avoid displaying a bogus
        negative value.

        * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
        `error', not SYMBOL_NAME itself.

        * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
        character arguments to `error'.

        * charset.c (check_iso_charset_parameter): Fix incorrect argument

        Define only if needed.

        * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
        by pacifying GCC about it.  Maybe it's time to retire it?
        * xfaces.c (USG, __TIMEVAL__): Likewise.

        * dispextern.h (struct redisplay_interface): Rename param
        to avoid shadowing.
        * termhooks.h (struct terminal): Likewise.
        * xterm.c (xembed_send_message): Likewise.

        * insdel.c (make_gap_smaller): Define only if
        USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.

        * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
        it.

        * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
        so that we aren't warned about unused symbols.

        only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.

        * bitmaps: Change bitmaps from unsigned char back to the X11
        compatible char.  Avoid the old compiler warnings about

        than 0xab.

        * xgselect.c (xgselect_initialize): Check vs interface

        * nsfont.m: Fixed bugs in ns_get_family and
        ns_descriptor_to_entity that were caused by using free to
        deallocate memory blocks that were allocated by xmalloc (via

        XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
        --enable-checking=xmallocoverrun).  xfree is now used to
        deallocate these memory blocks.

        font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
        * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
        was inaccessible from Lisp.
        (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
        * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.

        alloc.c: Import and export fewer symbols, and remove unused items.
        * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
        is defined.
        (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
        it's not optimized away by whole-program optimization.
        (message_enable_multibyte, free_misc): Remove.
        (catchlist, handlerlist, mark_backtrace):
        Declare only if BYTE_MARK_STACK.
        (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
        * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
        (message_enable_multibyte): Remove decl.
        (free_misc, interval_free_list, float_block, float_block_index):
        (n_float_blocks, float_free_list, cons_block, cons_block_index):
        (cons_free_list, last_marked_index):
        Now static.
        (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
        * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
        (mark_backtrace): Define only if BYTE_MARK_STACK.
        * xdisp.c (message_enable_multibyte): Now static.

        Declare Lisp_Object Q* variables to be 'static' if not exported.
        This makes it easier for human readers (and static analyzers)
        to see whether these variables are used from other modules.
        * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
        * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
        * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

        * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
        Remove decls of unexported vars.
        * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.

        * lisp.h (DEFINE_FUNC): Make sname 'static'.

        Make Emacs functions such as Fatom 'static' by default.
        This makes it easier for human readers (and static analyzers)
        to see whether these functions can be called from other modules.
        DEFUN now defines a static function.  To make the function external
        so that it can be used in other C modules, use the new macro DEFUE.
        * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
        (Finit_image_library):
        (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
        (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
        (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
        Remove decls, since these functions are now static.
        (Funintern, Fget_internal_run_time): New decls, since these functions
        were already external.

        * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
        * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

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

        * fileio.c (Fmake_symbolic_link): New forward static decl.
        * image.c (Finit_image_library): New forward static decl.
        * insdel.c (Fcombine_after_change_execute): Make forward decl static.
        * intervals.h (Fprevious_property_change):
        (Fremove_list_of_text_properties): Remove decls.
        * keyboard.c (Fthis_command_keys): Remove decl.
        (Fcommand_execute): New forward static decl.
        * keymap.c (Flookup_key): New forward static decl.

        Now internal.
        (Fset_window_margins, Fset_window_vscroll): New forward static decls.
        * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.

2011-04-14  Andreas Schwab  <schwab@linux-m68k.org>

        * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
        change.  (Bug#8496)

2011-04-13  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
        when at ZV.  (Bug#8487)

2011-04-12  Andreas Schwab  <schwab@linux-m68k.org>

        * charset.c (Fclear_charset_maps): Use xfree instead of free.
        (Bug#8437)
        * keyboard.c (parse_tool_bar_item): Likewise.
        * sound.c (sound_cleanup, alsa_close): Likewise.
        * termcap.c (tgetent): Likewise.
        * xfns.c (x_default_font_parameter): Likewise.
        * xsettings.c (read_and_apply_settings): Likewise.

        * alloc.c (overrun_check_malloc, overrun_check_realloc)
        (overrun_check_free): Protoize.

2011-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (emacs_read, emacs_write): Check for negative sizes
        since callers should never pass a negative size.
        Change the signature to match that of plain 'read' and 'write'; see
        <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
        * lisp.h: Update prototypes of emacs_write and emacs_read.

2011-04-11  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (redisplay_window): Don't try to determine the character
        position of the scroll margin if the window start point w->startp
        is outside the buffer's accessible region.  (Bug#8468)

2011-04-10  Eli Zaretskii  <eliz@gnu.org>

        Fix write-region and its subroutines for buffers > 2GB.
        * fileio.c (a_write, e_write): Modify declaration of arguments and
        local variables to support buffers larger than 2GB.
        (Fcopy_file): Use EMACS_INT for return value of emacs_read.

        * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
        argument, local variables, and return value.

        * lisp.h: Update prototypes of emacs_write and emacs_read.

        * sound.c (vox_write): Use ssize_t for return value of emacs_write.

2011-04-10  Paul Eggert  <eggert@cs.ucla.edu>

        * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

        Fix more problems found by GCC 4.6.0's static checks.

        * xdisp.c (vmessage): Use a better test for character truncation.

        * charset.c (load_charset_map): <, not <=, for optimization,
        and to avoid potential problems with integer overflow.
        * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
        * casetab.c (set_identity, shuffle): Likewise.
        * editfns.c (Fformat): Likewise.
        * syntax.c (skip_chars): Likewise.

        * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
        This also lets GCC 4.6.0 generate slightly better loop code.

        * callint.c (Fcall_interactively): <, not <=, for optimization.
        (Fcall_interactively): Count the number of arguments produced,
        not the number of arguments given.  This is simpler and lets GCC
        4.6.0 generate slightly better code.

        * ftfont.c: Distingish more carefully between FcChar8 and char.
        The previous code passed unsigned char * to a functions like
        strlen and xstrcasecmp that expect char *, which does not
        conform to the C standard.
        (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
        arguments to FcPatternGetString, and explicitly cast FcChar8 * to
        char * when the C standard requires it.

        * keyboard.c (read_char): Remove unused var.

        * eval.c: Port to Windows vsnprintf (Bug#8435).
        Include <limits.h>.
        (SIZE_MAX): Define if the headers do not.
        (verror): Do not give up if vsnprintf returns a negative count.
        Instead, grow the buffer.  This ports to Windows vsnprintf, which
        does not conform to C99.  Problem reported by Eli Zaretskii.
        Also, simplify the allocation scheme, by avoiding the need for
        calling realloc, and removing the ALLOCATED variable.

        * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.

        Remove invocations of doprnt, as Emacs now uses vsnprintf.
        But keep the doprint source code for now, as we might revamp it
        and use it again (Bug#8435).
        * lisp.h (doprnt): Remove.
        * Makefile.in (base_obj): Remove doprnt.o.
        * deps.mk (doprnt.o): Remove.

        error: Print 32- and 64-bit integers portably (Bug#8435).
        Without this change, on typical 64-bit hosts error ("...%d...", N)
        was used to print both 32- and 64-bit integers N, which relied on
        undefined behavior.
        * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
        New macro.
        * lisp.h (error, verror): Mark as printf-like functions.
        * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
        Report overflow in size calculations when allocating printf buffer.
        Do not truncate output string at its first null byte.
        * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
        Truncate the output at a character boundary, since vsnprintf does not
        do that.
        * charset.c (check_iso_charset_parameter): Convert internal
        character to string before calling 'error', since %c now has the
        printf meaning.
        * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
        overflow when computing char to be passed to 'error'.  Do not
        pass Lisp_Object to 'error'; pass the integer instead.
        * nsfns.m (Fns_do_applescript): Use int, not long, since it's
        formatted with plain %d.

        * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

        * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

        * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

        * xterm.c (x_catch_errors): Remove duplicate declaration.

        * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.

        * xdisp.c, lisp.h (message_nolog): Remove; unused.

2011-04-10  Jim Meyering  <meyering@redhat.com>

        use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
        * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
        return ssize_t not "int", and use size_t as the buffer length.
        (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
        * gnutls.h: Update declarations.
        * process.c (read_process_output): Use ssize_t, to match.
        (send_process): Likewise.

2011-04-09  Chong Yidong  <cyd@stupidchicken.com>

        * image.c (Fimagemagick_types): Doc fix, and comment cleanup.

2011-04-09  Chong Yidong  <cyd@stupidchicken.com>

        * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
        Use unsigned char, to match FcChar8 type definition.

        * xterm.c (handle_one_xevent):
        * xmenu.c (create_and_show_popup_menu):
        * xselect.c (x_decline_selection_request)
        (x_reply_selection_request): Avoid type-punned deref of X events.

2011-04-09  Eli Zaretskii  <eliz@gnu.org>

        Fix some uses of `int' instead of EMACS_INT.
        * search.c (string_match_1, fast_string_match)
        (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
        (scan_buffer, find_next_newline_no_quit)
        (find_before_next_newline, search_command, Freplace_match)
        (Fmatch_data): Make some `int' variables be EMACS_INT.

        * xdisp.c (display_count_lines): 3rd argument and return value now
        EMACS_INT.  All callers changed.
        (pint2hrstr): Last argument is now EMACS_INT.

        * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
        (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
        (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

        (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
        (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
        Declare EMACS_INT.
        (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
        (encode_invocation_designation): Last argument P_NCHARS is now
        EMACS_INT.
        (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
        (produce_chars): from_nchars and to_nchars are now EMACS_INT.

        * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
        All users changed.

        * ccl.c (Fccl_execute_on_string): Declare some variables
        EMACS_INT.

2011-04-08  Samuel Thibault  <sthibault@debian.org>  (tiny change)

2011-04-08  Chong Yidong  <cyd@stupidchicken.com>

        * keyboard.c (read_char): Call Lisp function help-form-show,
        instead of using internal_with_output_to_temp_buffer.
        (Qhelp_form_show): New var.
        (syms_of_keyboard): Use DEFSYM macro.

        * print.c (internal_with_output_to_temp_buffer): Function deleted.

2011-04-06  Paul Eggert  <eggert@cs.ucla.edu>

        Fix more problems found by GCC 4.6.0's static checks.

        * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

        * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.

        * lisp.h (message, message_nolog, fatal): Mark as printf-like.

        * eval.c (Fsignal): Remove excess argument to 'fatal'.

        * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
        This avoids several warnings with gcc -Wstrict-overflow.
        (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
        directly, rather than having caller test rule sign.  This avoids
        some unnecessary tests.
        * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
        (COMPOSITION_ENCODE_RULE): Arguments now must be valid.  This
        affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

        by using the new macro.

        * textprop.c (set_text_properties_1): Change while to do-while,
        since the condition is always true at first.

        * intervals.c (graft_intervals_into_buffer): Mark var as used.

        (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.

        * print.c (print_error_message): Avoid int overflow.

        * font.c (font_list_entities): Redo for clarity,
        so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

        * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
        (font_score): Avoid potential overflow in diff calculation.

        * eval.c (funcall_lambda): Rename local to avoid shadowing.

        * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
        Otherwise, GCC 4.6.0 optimizes the loop check away since the check
        can always succeed if overflow has undefined behavior.

        (wordify): Omit three unnecessary tests.

        * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

        (timer_check_2): Mark vars as initialized.

        * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.

        * image.c (lookup_image): Remove var that is set but not used.
        (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.

        * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
        that are set but not used.

        * xfns.c (make_invisible_cursor): Don't return garbage
        if XCreateBitmapFromData fails (Bug#8410).

        * xselect.c (x_get_local_selection, x_handle_property_notify):
        Remove vars that are set but not used.

        * xfns.c (x_create_tip_frame): Remove var that is set but not used.
        (make_invisible_cursor): Initialize a possibly-uninitialized variable.

        * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
        Remove var that is set but not used.
        (scroll_bar_windows_size): Now size_t, not int.
        (x_send_scroll_bar_event): Use size_t, not int, for sizes.
        Check for overflow.

        * xfaces.c (realize_named_face): Remove vars that are set but not used.
        (map_tty_color) [!defined MSDOS]: Likewise.

        * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.

        * coding.c: Remove vars that are set but not used.
        (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
        All callers changed.
        (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
        (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
        (decode_coding_charset): Remove vars that are set but not used.

        * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
        that is set but not used.

        * print.c (print_object): Remove var that is set but not used.

        Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
        The gnulib version avoids calling malloc in the usual case,
        and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
        * fileio.c (Ffile_symlink_p): Use emacs_readlink.
        * filelock.c (current_lock_owner): Likewise.
        * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
        * sysdep.c: Include allocator.h, careadlinkat.h.
        (emacs_no_realloc_allocator): New static constant.
        (emacs_readlink): New function.
        * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
        ../lib/careadlinkat.h.

2011-04-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
        first non-nil return value).

2011-04-03  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
        if not defined (Bug#8403).

2011-04-02  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
        later (Bug#8403).

2011-04-01  Stefan Monnier  <monnier@iro.umontreal.ca>

        Add lexical binding.

        * window.c (Ftemp_output_buffer_show): New fun.
        (Fsave_window_excursion):
        * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

        * lread.c (lisp_file_lexically_bound_p): New function.
        (Fload): Bind Qlexical_binding.
        (readevalloop): Remove `evalfun' arg.
        Bind Qinternal_interpreter_environment.
        (Feval_buffer): Bind Qlexical_binding.
        (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
        Mark as dynamic.
        (syms_of_lread): Declare `lexical-binding'.

        * lisp.h (struct Lisp_Symbol): New field `declared_special'.

        * keyboard.c (eval_dyn): New fun.
        (menu_item_eval_property): Use it.

        * image.c (parse_image_spec): Use Ffunctionp.

        * fns.c (concat, mapcar1): Accept byte-code-functions.

        * eval.c (Fsetq): Handle lexical vars.
        (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
        (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
        (FletX, Flet): Obey lexical binding.
        (Fcommandp): Handle closures.
        (Feval): New `lexical' arg.
        (eval_sub): New function extracted from Feval.  Use it almost
        everywhere where Feval was used.  Look up vars in lexical env.
        Handle closures.
        (Ffunctionp): Move from subr.el.
        (Ffuncall): Handle closures.
        (apply_lambda): Remove `eval_flags'.
        (funcall_lambda): Handle closures and new byte-code-functions.
        (Fspecial_variable_p): New function.
        (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
        but without exporting it to Lisp.

        * doc.c (Fdocumentation, store_function_docstring):
        * data.c (Finteractive_form): Handle closures.

        * callint.c (Fcall_interactively): Preserve lexical-binding mode for
        interactive spec.

        New byte-codes.
        (exec_byte_code): New function extracted from Fbyte_code to handle new
        calling convention for byte-code-functions.  Add new byte-codes.

        * buffer.c (defvar_per_buffer): Set new `declared_special' field.

        * alloc.c (Fmake_symbol): Init new `declared_special' field.

2011-03-31  Juanma Barranquero  <lekktu@gmail.com>

        * xdisp.c (redisplay_internal): Fix prototype.

2011-03-31  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (SCROLL_LIMIT): New macro.
        (try_scrolling): Use it when setting scroll_limit.
        Limit scrolling to 100 screen lines.
        (redisplay_window): Even when falling back on "recentering",
        position point in the window according to scroll-conservatively,
        scroll-margin, and scroll-*-aggressively variables.  (Bug#6671)

        (try_scrolling): When point is above the window, allow searching
        as far as scroll_max, or one screenful, to compute vertical
        distance from PT to the scroll margin position.  This prevents
        try_scrolling from unnecessarily failing when
        scroll-conservatively is set to a value slightly larger than the
        window height.  Clean up the case of PT below the margin at bottom
        of window: scroll_max can no longer be INT_MAX.  When aggressive
        scrolling is in use, don't let point enter the opposite scroll
        margin as result of the scroll.
        (syms_of_xdisp) <scroll-conservatively>: Document the
        threshold of 100 lines for never-recentering scrolling.

2011-03-31  Juanma Barranquero  <lekktu@gmail.com>

        * dispextern.h (move_it_by_lines):
        * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
        since 2000-12-29T14:24:09Z!gerd@gnu.org.  All callers changed.
        (message_log_check_duplicate): Remove parameters `prev_bol' and
        `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org.  All callers changed.
        (redisplay_internal): Remove parameter `preserve_echo_area',
        unused since 1999-07-21T21:43:52Z!gerd@gnu.org.  All callers changed.

        * indent.c (Fvertical_motion):
        * window.c (window_scroll_pixel_based, Frecenter):
        Don't pass `need_y_p' to `move_it_by_lines'.

2011-03-30  Stefan Monnier  <monnier@iro.umontreal.ca>

        * eval.c (struct backtrace): Don't cheat with negative numbers, but do
        steal a few bits to be more compact.

        Remove unneeded casts.

        * bytecode.c (Fbyte_code): CAR and CDR can GC.

2011-03-30  Zachary Kanfer  <zkanfer@gmail.com>  (tiny change)

        * keyboard.c (Fexecute_extended_command): Do log the "suggest key
        binding" message (bug#7967).

2011-03-30  Paul Eggert  <eggert@cs.ucla.edu>

        Fix more problems found by GCC 4.6.0's static checks.

        * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
        Remove unused local var.

        * editfns.c (Fmessage_box): Remove unused local var.

        * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
        (note_mode_line_or_margin_highlight, note_mouse_highlight):
        Omit unused local vars.
        * window.c (shrink_windows): Omit unused local var.
        * menu.c (digest_single_submenu): Omit unused local var.
        * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
        Omit unused local var.

        * keyboard.c (parse_modifiers_uncached, parse_modifiers):
        Don't assume string length fits in int.
        (keyremap_step, read_key_sequence): Use size_t for sizes.
        (read_key_sequence): Don't check last_real_key_start redundantly.

        * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
        instead of alloca (Bug#8344).

        * eval.c (Fbacktrace): Don't assume nargs fits in int.
        (Fbacktrace_frame): Don't assume nframes fits in int.

        * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

        * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
        concerns.

        * term.c (produce_glyphless_glyph): Remove unnecessary test.

        * cm.c (calccost): Turn while-do into do-while, for clarity.

        * keyboard.c (syms_of_keyboard): Use the same style as later
        in this function when indexing through an array.  This also
        works around GCC bug 48267.

        * image.c (tiff_load): Fix off-by-one image count (Bug#8336).

        * xselect.c (x_check_property_data): Return correct size (Bug#8335).

        * chartab.c (sub_char_table_ref_and_range): Redo for slight
        efficiency gain, and to bypass a gcc -Wstrict-overflow warning.

        * keyboard.c, keyboard.h (num_input_events): Now size_t.
        This avoids undefined behavior on integer overflow, and is a bit
        more convenient anyway since it is compared to a size_t variable.

        Variadic C functions now count arguments with size_t, not int.
        This avoids an unnecessary limitation on 64-bit machines, which
        caused (substring ...) to crash on large vectors (Bug#8344).
        * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
        (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

        (funcall_lambda, mark_backtrace): Likewise.
        * fns.c (concat): Likewise.
        * frame.c (x_set_frame_parameters): Likewise.
        * fns.c (get_key_arg): Now accepts and returns size_t, and returns
        0 if not found, not -1.  All callers changed.

        * alloc.c (garbage_collect): Don't assume stack size fits in int.
        (stack_copy_size): Now size_t, not int.
        (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

        Vcommand_hook_internal.

        (funcall_nil, funcall_not): New functions.
        (run_hook_with_args): Call each function through a `funcall' argument.
        Remove `cond' argument, now redundant.

        (Frun_hook_with_args_until_failure): Adjust accordingly.
        (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

2011-03-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix more problems found by GCC 4.5.2's static checks.

        * coding.c (encode_coding_raw_text): Avoid unnecessary test
        the first time through the loop, since we know p0 < p1 then.
        This also avoids a gcc -Wstrict-overflow warning.

        * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
        leading to a memory leak, possible in functions like
        load_charset_map_from_file that can allocate an unbounded number
        of objects (Bug#8318).

        * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
        that could (at least in theory) be that large.

        * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
        This is less likely to overflow, and avoids undefined behavior if
        overflow does occur.  All callers changed.  Use strtoul to scan
        for the unsigned long integer.
        (pint2hrstr): Simplify and tune code slightly.
        This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

        * scroll.c (do_scrolling): Work around GCC bug 48228.
        See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

        * frame.c (Fmodify_frame_parameters): Simplify loop counter.
        This also avoids a warning with gcc -Wstrict-overflow.
        (validate_x_resource_name): Simplify count usage.
        This also avoids a warning with gcc -Wstrict-overflow.

        * fileio.c (Fcopy_file): Report error if fchown or fchmod
        fail (Bug#8306).

        * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).

        * process.c (Fmake_network_process): Use socklen_t, not int,
        where POSIX says socklen_t is required in portable programs.
        This fixes a porting bug on hosts like 64-bit HP-UX, where
        socklen_t is wider than int (Bug#8277).
        (Fmake_network_process, server_accept_connection):
        (wait_reading_process_output, read_process_output):
        Likewise.

        * process.c: Rename or move locals to avoid shadowing.
        (list_processes_1, Fmake_network_process):
        (read_process_output_error_handler, exec_sentinel_error_handler):
        Rename or move locals.
        (Fmake_network_process): Define label "retry_connect" only if needed.

        (process_send_signal): Add cast to avoid pointer signedness problem.
        (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
        (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).

        Make tparam.h and terminfo.c consistent.
        * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
        Include tparam.h instead, since it declares them.
        * cm.h (PC): Remove extern decl; tparam.h now does this.
        * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
        * terminfo.c: Include tparam.h, to check interfaces.
        (tparm): Make 1st arg a const pointer in decl.  Put it at top level.
        (tparam): Adjust signature to match interface in tparam.h;
        this removes some undefined behavior.  Check that outstring and len
        are zero, which they always are with Emacs.
        * tparam.h (PC, BC, UP): New extern decls.

        * xftfont.c (xftfont_shape): Now static, and defined only if needed.
        (xftfont_open): Rename locals to avoid shadowing.

        * xfont.c (xfont_list_family): Mark var as initialized.

        * xml.c (make_dom): Now static.

        * composite.c (composition_compute_stop_pos): Rename local to
        avoid shadowing.
        (composition_reseat_it): Remove unused locals.
        (find_automatic_composition, composition_adjust_point): Likewise.
        (composition_update_it): Mark var as initialized.
        (find_automatic_composition): Mark vars as initialized,
        with a FIXME (Bug#8290).

        * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
        (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):

        (BUF_DEC_POS): Be more systematic about renaming local temporaries
        to avoid shadowing.

        * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

        * atimer.c (start_atimer, append_atimer_lists, set_alarm):
        Rename locals to avoid shadowing.

        * sound.c (wav_play, au_play, Fplay_sound_internal):
        Fix pointer signedness.
        (alsa_choose_format): Remove unused local var.
        (wav_play): Initialize a variable to 0, to prevent undefined
        behavior (Bug#8278).

        * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.

        * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.

        * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
        clobbering (Bug#8298).
        * sysdep.c (sys_subshell): Likewise.
        Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.

        * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
        This should get cleaned up, so that child_setup has the
        same signature on all platforms.

        * callproc.c (call_process_cleanup): Now static.
        (relocate_fd): Rename locals to avoid shadowing.

2011-03-22  Chong Yidong  <cyd@stupidchicken.com>

        * xterm.c (x_clear_frame): Remove XClearWindow call.  This appears
        not to be necessary, and produces flickering.

2011-03-20  Glenn Morris  <rgm@gnu.org>

        * config.in: Remove file.

2011-03-20  Juanma Barranquero  <lekktu@gmail.com>

        * xfaces.c (Fx_load_color_file):
        Read color file from absolute filename (bug#8250).

2011-03-19  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in: Update dependencies.

2011-03-17  Eli Zaretskii  <eliz@gnu.org>

        * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

        of the new macros.
        (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
        argument, for consistency with GCPRO2_VAR, etc: it is now the

        Rename locals to avoid shadowing.

        Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
        An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
        dired.c's scmp function, had undefined behavior.
        * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
        (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
        * buffer.h: ... to here, because these macros use current_buffer,
        and the new implementation with inline functions needs to have
        current_buffer in scope now, rather than later when the macros
        are used.
        (downcase, upcase1): New static inline functions.
        (DOWNCASE, UPCASE1): Reimplement using these functions.
        This avoids undefined behavior in expressions like

        (Ftry_completion, Fall_completions): Rename or remove locals
        to avoid shadowing.

        * marker.c (bytepos_to_charpos): Remove; unused.

        so that gcc does not warn that these functions aren't declared.

        * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
        (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
        (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
        (copy_text): Remove unused local var.

        * filelock.c (within_one_second): Now static.
        (lock_file_1): Rename local to avoid shadowing.

        * buffer.c (fix_overlays_before): Mark locals as initialized.
        (fix_start_end_in_overlays): Likewise.  This function should be
        simplified by using pointers-to-pointers, but that's a different
        matter.
        (switch_to_buffer_1): Now static.
        (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
        (report_overlay_modification): Rename locals to avoid shadowing.

        to suppress a gcc -Wclobbered warning that does not seem to be right.
        (MAXPATHLEN): Define only if needed.

        * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
        (copy_keymap_item, append_key, push_text_char_description):
        Now static.
        (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
        (DENSE_TABLE_SIZE): Remove; unused.
        (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
        (describe_map_tree):
        Rename locals to avoid shadowing.

        * keyboard.c: Declare functions static if they are not used elsewhere.
        (echo_char, echo_dash, cmd_error, top_level_2):

        if GCC considers string literals to be constants.

        * lisp.h (fatal_error_signal): Add decl, since it's exported.

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