        with the same face.
        (turn_off_face): Reset standout_mode only if

        * xterm.c (x_draw_bar_cursor): If cursor is on an image, draw a
        box cursor because that's better visible for large images.

        of nested comments by checking that the comment-starter we found
        does indeed match the comment-ender.
        (scan_sexps_forward, scan_sexps_forward):
        Ignore excessive opening parenthesis rather than throwing an error.

2000-07-11  Gerd Moellmann  <gerd@gnu.org>

        * doc.c (Fsubstitute_command_keys): Handle case that a GC
        in Fwhere_is_internal or get_keymap_1 relocates string contents.

        * dispnew.c (direct_output_forward_char): Give up if currently
        displaying a message instead of the minibuffer contents.

        with that of Emacs 20.

2000-07-07  Gerd Moellmann  <gerd@gnu.org>

        * eval.c (Fsignal): Handle case that backtrace_list is null.

2000-07-07  Kenichi Handa  <handa@etl.go.jp>

        * ccl.c (Fccl_execute): Typo fixed.

        * vm-limit.c (check_memory_limits) [REL_ALLOC]: Use real_morecore
        when non-NULL instead of __morecore, to take account of buffer
        memory.  This also solves a problem with spurious memory warnings
        on Windows.

        * ralloc.c: Make real_morecore non-static.

        * eval.c (internal_condition_case): Comment out abort if
        interrupt_input_blocked is not zero.

        * makefile.nt: Add support for `bootstrap' and related targets.
        Include minimal debug info in emacs.exe in release build.
        Remove all dependencies on lisp.h, and fixup some others.

        * w32.c (init_environment): Install code from 20.7 for providing
        default values for environment variables, based on the
        executable's own location.
        (map_w32_filename): Handle filenames that are longer than

        here via blockinput.h).

2000-07-05  Stefan Monnier  <monnier@cs.yale.edu>

        * w32menu.c (w32_menu_display_help):
        * xmenu.c (menu_help_callback): Use show_help_echo.

        * keyboard.h (show_help_echo): Declare.

        (follow_key): Pass `autoload' to get_keyelt.

        * xterm.c (note_mode_line_highlight, note_mouse_highlight)
        (note_tool_bar_highlight, XTread_socket):
        * msdos.c (IT_note_mode_line_highlight, IT_note_mouse_highlight)
        (dos_rawgetc):

        (x_produce_image_glyph, x_append_stretch_glyph): Accomodate to
        changes in struct glyph starting 1999-12-27.  Some bit-fields of
        struct glyph were not set, which made glyphs unequal when compared
        with GLYPH_EQUAL_P.  Redisplay outputs such glyphs, and flickering
        effects were the result.  This also depended on the contents of
        memory returned by xmalloc.  If flickering happens again, activate
        the code in clear_glyph_row that's in #if 0.  If the flickering is
        gone with that, chances are that it is caused by something
        similar.

        * dispnew.c (clear_glyph_row): Add debug code in #if 0.

        * window.c (add_window_to_list): Add parameter LIST.
        (window_list): Order list so that, for each frame, windows are
        in canonical order, and so that frames appear in the list in
        the order given by Vframe_list.
        (next_window): Reverse the handling of NEXT_P.

2000-07-04  Gerd Moellmann  <gerd@gnu.org>

        * window.c (Vwindow_list): New variable.
        (make_window, delete_window): Set Vwindow_list to nil.
        (check_window_containing): New function.
        (window_from_coordinates): Rewritten.

        (Fwindow_list): New function.
        (Fother_window): Cleaned up.
        (foreach_window): Add a longer "variable argument list".  Let
        callback function return 0 to indicate that cycling over windows
        should stop.
        (foreach_window_1): Likewise.

        (init_window): New function.

        composition property value a copy.

        * fns.c (concat): While copying text properties, make each
        composition property value a copy.

        * fns.c (sweep_weak_table): Mark only objects that are not
        marked already.

        * frame.c (next_frame, prev_frame): If MINIBUF is a window,
        include those frames as candidates which have their focus
        redirected to the minibuffer frame.

2000-07-03  Stefan Monnier  <monnier@cs.yale.edu>

        * fns.c (Fputhash): Return `value' rather than nil.

2000-06-30  Gerd Moellmann  <gerd@gnu.org>

        * frame.c (next_frame): Don't check focus redirection in case
        MINIBUF is a window.  Doing so excludes frames using MINIBUF
        unless their focus is redirected, which contradicts the
        specification of next-frame, and leads to infinite loops in
        certain situations when cycling through windows with next-window.

2000-06-30  Kenichi Handa  <handa@etl.go.jp>

        * coding.c (code_convert_region): Even if the length of text is

2000-06-28  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c (try_window_reusing_current_matrix): Don't try to reuse
        the display if windows_or_buffers_changed.

        (row_entry_pool, row_entry_pool_size, row_entry_idx, row_table)
        (row_table_size, old_lines, new_lines, old_lines_size)
        (new_lines_size, run_pool, runs_size, runs): New variables.
        (add_row_entry): New function.
        (scrolling_window): Use data structures allocated with xmalloc and
        held in global variables, instead of allocating them with alloca and
        holding them in local variables.  Use a larger hash table whose
        size depends on glyph matrix sizes.  Don't use bzero to clear the
        hash table; instead, clear used slots only.

        * fns.c (next_almost_prime): Make it externally visible.

        * syntax.c (back_comment): Simplify string-parity counting (with

        a "string_lossage" position.  Fixes the case:  " /* " /* " */.

        it as an integer.

        * keymap.c (Fwhere_is_internal): Rename argument "keymap" to
        "xkeymap" to avoid shadowing the "enum map_type" value that needs
        to be passed to get_local_map.

        * sound.c (Fplay_sound): Don't call make_number on
        Frun_hook_with_args count argument.

        * xterm.c (x_send_scroll_bar_event): Fudge lisp object/integer
        for lisp objects in X event structure data field, when lisp

        function does something useful even when message_buf_print is
        already set.

        * xdisp.c (message_truncate_lines, Qmessage_truncate_lines): New
        variables.
        (ensure_echo_area_buffers): Initialize echo buffer's
        truncate lines setting to nil.
        (with_echo_area_buffer): Don't set the echo buffer's truncate
        lines setting here.
        (set_message_1): Set it here instead, based on the value

        * xterm.c (XTread_socket) <FocusIn>: Queue a FOCUS_IN_EVENT which
        will be translated to a switch-frame event when reading the
        event queue.  This is necessary because Emacs otherwise won't
        perform a switch-frame to a new frame until some other event, for
        example a keystroke event, forces it to do so.  This has various
        effects, one visible being that the cursor of a frame created with
        C-x 5 2 or switched to with a window manager key binding like
        A-TAB stays hollow because selected_window isn't on the newly
        focused frame until the switch-frame is performed.

        generating a switch-frame event if necessary.

        * window.c (displayed_window_lines): Take empty lines at
        the bottom of a window into account.

        * window.c (displayed_window_lines): New function.
        (Fmove_to_window_line): Use displayed_window_lines to determine
        the number of lines to move, instead of using the window's height.

        * lread.c (readevalloop): If READCHARFUN sets point to ZV, arrange
        to stop reading, even if the form read sets point to a different
        value when evaluated.

        (dump_glyph_row): Print values of new flags.
        (redisplay_window) <cursor movement in unchanged window>: When
        point has been moved forward, and PT is at the end of the cursor
        row, don't place the cursor in the next row if the cursor row ends
        in the middle of a character or at ZV.

        * dispextern.h (struct it): Add starts_in_middle_of_char_p.
        (struct glyph_row): Add starts_in_middle_of_char_p and
        ends_in_middle_of_char_p.
        (MATRIX_ROW_ENDS_IN_MIDDLE_OF_CHAR_P): Test row's
        ends_in_middle_of_char_p flag.

        attention to a padding glyph.

2000-06-05  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c (redisplay_window): Always use set_buffer_internal_1.

2000-06-05  Dave Love  <fx@gnu.org>

        * xdisp.c: Include fontset.h.

        that we don't have to handle the special cases any more.

        optimization.
        (re_search_2): Don't bother with `room'.
        (skip_one_char): New function.
        (skip_noops): Simplify since `memory' is not needed any more.

        on_failure_keep_string_jump (and redirect the end-of-loop jump)
        rather than on_failure_jump_exclusive.

2000-03-19  Gerd Moellmann  <gerd@gnu.org>

        * xfns.c (select_visual): Don't set dpyinfo->n_planes to the

2000-03-15  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (re_match_2): Fix string shortening (to fit `stop') to
        make sure POINTER_TO_OFFSET gives the same value before and after

        (at_(beg|end)line_loc_p): Fix argument's types.
        (re_compile_fastmap): Ifdef out failure_stack_ptr to shut up gcc.

        * regex.c: Declare a new type `re_char' used throughout the code
        for the string char type.  It's `const unsigned char' to match the
        rest of Emacs.  Consistently make sure all pointers to strings use
        it and make sure all pointers into the pattern use `unsigned
        char'.
        (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
        GET_CHAR_AFTER_2.  Also merge wordbound and notwordbound to reduce
        code duplication.

        * charset.h (GET_CHAR_AFTER_2): Remove.
        (GET_CHAR_BEFORE_2): Use unsigned chars, like everywhere else.

2000-03-12  Ken Raeburn  <raeburn@gnu.org>

        * Makefile.in (temacs): Evaluate ALL_LDFLAGS into a temporary

2000-03-12  Dave Love  <fx@gnu.org>

        * unexelf.c: Restore changes of 1999-10-19.
        (unexec): Don't adjust bss for sbss type SHT_PROGBITS; otherwise
        fix its type and alignment; copy it from current process.

2000-03-12  Gerd Moellmann  <gerd@gnu.org>

        * atimer.c (cancel_atimer): Break out of the loop as soon as timer

        (IT_frame_up_to_date): Call IT_set_cursor_type, in case the cursor
        type has changed.
        (IT_set_frame_parameters): Call IT_set_cursor_type if the frame
        parameters specify the cursor.  Make qreverse a global
        variable (renamed to Qreverse).

2000-03-09  Gerd Moellmann  <gerd@gnu.org>

        * fns.c (Fy_or_n_p): Cancel busy-cursor.

2000-03-08  Stefan Monnier  <monnier@cs.yale.edu>

        This is a big redesign of failure-stack and register handling, prompted
        by bugs revealed when trying to add shy-groups.  Overall, what happened
        is that loops are now structured a little differently, groups can be
        shy and the code is a little simpler.

        * regex.h: Update the copyright.
        (RE_SHY_GROUPS): New value.
        (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
        (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.

        * regex.c (enum re_opcode_t): Remove jump_past_alt,
        maybe_pop_jump, push_dummy_failure and dumy_failure_jump.  Add
        on_failure_jump_(exclusive, loop and smart).  Also fix the comment
        for (start|stop)_memory since they now only take one argument (the
        second has becomes unnecessary).
        (print_partial_compiled_pattern): Adjust for changes in
        re_opcode_t.
        (print_compiled_pattern): Use %ld to printf long ints and flush to
        make debugging a little easier.
        (union fail_stack_elt): Make the integer unsigned.
        (struct fail_stack_type): Add a `frame' element.
        (INIT_FAIL_STACK): Init `frame' as well.

        (TOP_FAILURE_HANDLE): New macros for the cycle detection.
        (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
        (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
        macros.
        (PUSH_FAILURE_POINT): Don't push registers any more.  The pattern
        address pushed is not the destination of the jump but the source
        of it instead.
        (NUM_FAILURE_ITEMS): Remove.
        (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
        registers before the actual failure point).  Don't hardcode any
        meaning for str==NULL anymore.
        (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
        (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
        Remove.
        (REG_UNSET_VALUE): Use NULL (why not?).
        (compile_range): Remove declaration since it doesn't exist.
        (struct compile_stack_elt_t): Remove inner_group_offset.
        (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
        (regex_grow_registers): Remove dead code.
        (FIXUP_ALT_JUMP): New macro.
        (regex_compile): Add shy-groups Change loops to use
        on_failure_jump_smart&jump instead of
        on_failure_jump&maybe_pop_jump.  Change + loops to eliminate the
        initial (dummy_failure_)jump.  Remove c1_base (looks like unused
        variable to me).  Use `jump' instead of `jump_past_alt' and don't
        bother with push_dummy_failure in alternatives since it is now
        unnecessary.  Use FIXUP_ALT_JUMP.  Eliminate a useless `#ifdef
        emacs' for (re)allocating the stack.
        (re_compile_fastmap): Remove dead variables i and num_regs.  Exit
        from loop when bufp->can_be_null rather than jumping to `done'.
        Avoid jumping backwards so as to ensure termination.  Use
        PATTERN_STACK_EMPTY and POP_PATTERN_OP.  Improved handling of
        backreferences.  Remove dead code in handling of `anychar'.
        (skip_noops, mutually_exclusive_p): New functions taken from the
        handling of `maybe_pop_jump' in re_match_2_internal.  Slightly
        improve mutually_exclusive_p to handle ".+\n".
        (lowest_active_reg, highest_active_reg,
        NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
        (re_match_2_internal): Use %p instead of 0x%x when printf'ing
        ptrs.  Don't SET_REGS_MATCHED anymore.  Remove many dead
        variables.  Push register (in `start_memory') on the stack rather
        than storing it in old_reg(start|end).  Remove the cycle detection
        from `stop_memory', replaced by the use of on_failure_jump_loop
        for greedy loops.  Add code for the new on_failure_jump_<foo>.
        Remove ad-hoc code in `on_failure_jump' to push more registers in
        the case of a loop.  Take out code from `maybe_pop_jump' into
        separate functions and adapt it to the semantics of
        `on_failure_jump_smart'.  Remove jump_past_alt, dummy_failure_jump
        and push_dummy_failure.  Remove dummy_failure handling and
        handling of `failures to jump to on_failure_jump' (this last one
        was already dead code, it seems).
        (group_match_null_string_p, alt_match_null_string_p)
        (common_op_match_null_string_p): Remove.

2000-03-08  Dave Love  <fx@gnu.org>

        returns a mask not set in PRIORITIES.
        (detect_eol_type_in_2_octet_form): New function.
        (detect_eol): selects detect_eol_type_XXX to call according to
        cooding->category_idx.
        (detect_coding_system): Remove `nil' coding-system in the result.
        (Fupdate_coding_systems_internal): Update all coding-categories.
