        window's start when its top position hasn't changed.  If we do,
        this will set the window's optional_new_start, which act's like a
        force_start during redisplay with C-x 1 M-> under particular
        circumstances (see report from Per Starback to emacs-pretest-bug
        from 2000-12-13.).

        system doesn't tell us directly.
        (Fx_display_visual_class): Implement properly.

2001-01-02  Gerd Moellmann  <gerd@gnu.org>

        * window.c (Frecenter): Handle centering in graphical frames
        specially.  Centering on the basis of line counts doesn't work
        reliably with variable-height lines.

        descent value to avoid displaying terribly tall empty boxes.
        (expose_area): Pass x-coordinate relative to the exposed
        area to x_draw_glyphs instead of a window-relative coordinate.

2000-12-05  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c (next_element_from_ellipsis): Save face before selective
        display in saved_face_id, and set face_before_selective_p.

        use the right face id when producing spaces at the end of
        the line.

        * xterm.c (expose_area): Pass x-coordinate relative to the exposed
        area to x_draw_glyphs instead of a window-relative coordinate.

        * fileio.c (auto_save_error): Add parameter ERROR.  Show the
        error in the message.

        * keyboard.c (Fread_key_sequence): Don't start the busy cursor
        timer after having read a key.  It's not good for code reading
        several keys in a loop, like an input method.

        record undo information for format-decode.

        * undo.c (Fprimitive_undo): Bind inhibit-read-only to t if

        * keyboard.c (record_char): Record `help-echo' input events
        in recent_keys only if they display some help.  Don't record

        * editfns.c (save_excursion_restore): Don't move point
        in another window if it is showing the wrong buffer.
        Avoid the call to Fwindow_live_p, for speed.

2000-12-04  Kenichi Handa  <handa@etl.go.jp>

        * xfaces.c (struct font_name): New member registry_priority.

        (font_list): Include fonts of all alternative registries.
        (FONT_POINT_SIZE_QUANTUM): New macro.
        (better_font_p): Ignore point size difference less than

        a composition is not found, use 1 pixel dot ascent and 0 dot
        descent value to avoid displaying terribly tall empty boxes.

        correctly for single byte character case.
        (w32_per_char_metric): Do not try to make any assumptions about
        the metrics of BDF fonts.
        (x_estimate_mode_line_height): If `mode-line' face
        hasn't a font, use that of the frame, as drawing glyphs
        does.
        (note_mouse_highlight): Change the cursor shape on the vertical
        border between windows [not enabled].

        * w32term.h (struct w32_output): Add member horizontal_drag_cursor.

        * w32fns.c (Fx_create_frame): Reintroduce the call to
        face-set-after-frame-defaults.

        NULL.

2000-12-01  Gerd Moellmann  <gerd@gnu.org>

        * xterm.c (x_calc_absolute_position): Don't subtract menubar's
        height for YNegative.
        (x_calc_absolute_position) [USE_MOTIF]: Use the column widget's
        height; also see comment there.

        * window.c (coordinates_in_window): Handle computations for
        positions on the vertical bar and fringes differently for
        window-system frames.  Consider some pixels near the vertical bar
        as on the bar if the frame doesn't have vertical scroll bars.
        Associate positions between mode or header lines with the
        right window, the left one.

2000-12-01  Jason Rumney  <jasonr@gnu.org>

        * w32term.c (w32_clear_window): Avoid clearing an invalid frame.

2000-11-30  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c (echo_area_display): If cursor is in the echo area, make
        sure that the next redisplay displays the minibuffer, so that
        the cursor will be replaced with what the minibuffer wants.

        * xterm.c: Test USE_TOOLKIT_SCROLL_BARS everywhere with #ifdef and
        #ifndef instead of using #if.
        (XTread_socket) [USE_MOTIF] <KeyPress>: Call XmIsScrollBar only if
        USE_TOOLKIT_SCROLL_BARS is defined.

2000-11-30  Jason Rumney  <jasonr@gnu.org>

        * w32fns.c (x_set_cursor_color): Use x_update_cursor instead of

        * xterm.c (x_estimate_mode_line_height): If `mode-line' face
        hasn't a font, use that of the frame, as drawing glyphs
        does.

2000-11-29  Stefan Monnier  <monnier@cs.yale.edu>

        * eval.c (Frun_hooks): Allow 0 arguments.

2000-11-29  Gerd Moellmann  <gerd@gnu.org>

        * xterm.c (XTmouse_position) [USE_X_TOOLKIT]: When the mouse
        is over the menu bar widget, say it's not on the frame.

        * xfns.c (Fx_create_frame): Reintroduce the call to
        face-set-after-frame-defaults.

        * eval.c (Fsignal): Reset handling_signal.

2000-11-28  Gerd Moellmann  <gerd@gnu.org>

        * xselect.c: Update copyright.

        * window.c (coordinates_in_window): If on a mode or header line,
        but sufficiently close to its start, return ``on vertical
        border''.  This gives us a way to drag windows horizontally when
        using toolkit scroll bars.

        * xterm.c (note_mouse_highlight): Change the cursor shape
        on the vertical border between windows.

        * xterm.h (struct x_output): Add member horizontal_drag_cursor.

        * textprop.c (text_read_only): New function.
        (verify_interval_modification): Use it instead of signaling
        `text-read-only'.  This makes it easier to catch this error
        with a breakpoint.: 

        * xdisp.c (forward_to_next_line_start): Check for newlines, 
        not end of line, which includes CR.

2000-11-28  Kenichi Handa  <handa@etl.go.jp>

        * coding.c (Ffind_coding_systems_region_internal): Be sure to
        include no-conversion.

        * w32fns.c (w32_load_system_font): Always mark font as double byte
        if codepage is unicode.

2000-11-27  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c (forward_to_next_line_start): If already on a newline,
        just consume it to avoid unintended skipping over invisible text
        below.

        * keyboard.c (lucid_event_type_list_p): Handle `help-echo',
        `vertical-line', `mode-line' and `header-line' events.

        * xdisp.c (try_window_id): Avoid starting to display in the middle
         of a character, a TAB for instance.  This is easier than to set
         up the iterator exactly, and it's not a frequent case, so the
         additional effort wouldn't really pay off.

2000-11-26  Andrew Choi  <akochoi@i-cable.com>

        * emacs.c (main) [macintosh]: Call syms_of_frame before calling
        init_window_once.

2000-11-25  Jason Rumney  <jasonr@gnu.org>

        * keyboard.c (make_lispy_event) [mouse_wheel, drag_n_drop]: Args
        to window_from_coordinates should be pixel coordinates.

        * w32fns.c (x_to_w32_font): Do not filter out italic fonts, as new
        redisplay handles them properly.

2000-11-25  Miles Bader  <miles@gnu.org>

        * indent.c (compute_motion): Keep pos_byte in sync with pos.

2000-11-24  Jason Rumney  <jasonr@gnu.org>

        locale settings, if not set.

        * w32fns.c (x_set_tool_bar_lines): Clear internal border when
        making tool bar smaller. When clearing the frame, also
        clear current matrices. Clear frame when tool bar disappears.
        Don't use more lines for the tool-bar than is available.
        (x_change_window_heights): New function.

2000-11-24  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c (init_from_display_pos): If POS says we're already after
         an overlay string ending at POS, make sure to pop the iterator
         because it will be in front of that overlay string.  When POS is
         ZV, we've thereby also ``processed'' overlay strings at ZV.

        * xfaces.c (lface_from_face_name): Function comment fix.

2000-11-24  Miles Bader  <miles@gnu.org>

        * xdisp.c (display_menu_bar, display_mode_line): Change the way we
        apply `mode-line-inverse-video' -- zero means force display using
        the default face, non-zero means display using the specialized face.
        (syms_of_xdisp): `mode-line-inverse-video' defaults to true again.

2000-11-23  Kenichi Handa  <handa@etl.go.jp>

        * alloc.c (Fmake_string): Use MAX_MULTIBYTE_LENGTH, instead of
        hard coded `4'.

2000-11-23  Eli Zaretskii  <eliz@is.elta.co.il>

        * coding.c (decode_coding_emacs_mule): Fix the case of
        CODING_EOL_LF, which used uninitialized value of c.

2000-11-23  Stefan Monnier  <monnier@cs.yale.edu>

        * xdisp.c (syms_of_xdisp): Make fontification-functions buffer-local.

        * xdisp.c (update_tool_bar, build_desired_tool_bar_string): Change
        references to members deleted from struct frame to use the new
        ones.

        * dispnew.c (update_frame): Do nothing with frame's tool bar
        items.

        * alloc.c (mark_object) <frame>: Mark tool bar items differently.

        * w32term.c (x_tool_bar_item, w32_handle_tool_bar_click)
        (note_tool_bar_highlight): Change references to members deleted
        from struct frame to use the new ones.

2000-11-23  Miles Bader  <miles@gnu.org>

        * xdisp.c (display_menu_bar): Or `mode-line-inverse-video' with
        the face's inverse-video attribute, rather than overriding it.

2000-11-22  Gerd Moellmann  <gerd@gnu.org>

        * xfns.c (x_set_tool_bar_lines): Clear internal border when
        making tool bar smaller.

        <netdb.h>.

2000-11-21  Gerd Moellmann  <gerd@gnu.org>

        the menu bar when the tooltip is unmapped.

        * buffer.c (Fkill_buffer): Notice if the buffer to kill is the
        sole visible buffer when we're currently in the mini-buffer, and
        give up if so.
        
2000-11-21  Jason Rumney  <jasonr@gnu.org>

        * w32select.c (Fw32_set_clipboard_data): Save a copy of what is
        put on the clipboard.
        (Fw32_get_clipboard_data): Compare data on clipboard with saved
        copy of what Emacs last put there. If they are the same, do not
        use the clipboard copy to avoid losing data due to coding
        conversions. 

2000-11-22  Miles Bader  <miles@gnu.org>

        * minibuf.c (Vminibuffer_prompt_properties): New variable.

        ... #endif scope.

2000-11-20  Gerd Moellmann  <gerd@gnu.org>

        * xfns.c (x_create_tip_frame): Use CWSaveUnder only if the 
        screen supports it.

        * s/gnu-linux.h: Don't use `#cpu'.

        * buffer.c (MAP_FAILED): Define it as `((void *) -1)' if it's

        (x_send_scroll_bar_event): Store the window in scroll_bar_windows
        and store an index in the XClientMessageEvent.  Storing a

        transfers 32 bits.
        (x_scroll_bar_to_input_event): Get the window from
        scroll_bar_windows.

        (SCROLL_BAR_X_WIDGET): Get the widget via XtWindowToWidget.
        Take the X display as additional argument.
        (SET_SCROLL_BAR_X_WIDGET): Store the window of the widget, since
        `Widget' is a pointer type that's not easily stored in Lisp_Object
        form in a portable way.
        
        * dispnew.c (update_text_area): Fix last change.

2000-11-18  Gerd Moellmann  <gerd@gnu.org>

        * xdisp.c: Use BINDING_STACK_SIZE throughout.

        * xfns.c (x_set_tool_bar_lines): When clearing the frame, also
        clear current matrices.

        (PUSH_FAILURE_POINTER): Don't cast any more.
        (POP_FAILURE_REG_OR_COUNT): Remove the cast that strips `const'.
        We want GCC to complain, since this piece of code makes
        re_match non-reentrant, which *should* be fixed.

        (EXTEND_BUFFER): Use RETALLOC.
        (SET_LIST_BIT): Don't cast.

        (re_iswctype, re_wctype_to_bit): Make it crystal clear to GCC
        that those two functions will always properly return.
        (IMMEDIATE_QUIT_CHECK): Cast to void.

        Now also sets the new value (passed in a new argument).
        (re_match_2_internal): Use it.
        Also, use a new var `reg' of type size_t when looping through regs
        rather than reuse the inappropriate `mcnt'.

        * keymap.c (where_is_cache, where_is_cache_keymaps): New vars.
        (Fset_keymap_parent, store_in_keymap): Flush the where-is cache.

        (where_is_internal_1): Handle the case where we're filling the cache.
        (syms_of_keymap): Init and gcpro the where_is_cache(|_keymaps).

        is from C string, but we should encode it.  Before calling
        setup_raw_text_coding_system, be sure to flush out data by the
        previous coding system.

2000-10-25  Miles Bader  <miles@lsi.nec.co.jp>

        * buffer.c (overlays_at): Only let CHANGE_REQ inhibit an

        Handle the case where lookup-key returns an integer.
        (where_is_internal_1): Drop arg `keymap'. Don't check shadowing.
        (where_is_internal_2): Adapt to fewer args for where_is_internal_1.
        (Fwhere_is_internal): Allow `xkeymap' to be a list of keymaps.
        Simplify/rewrite the keymap-finding code.
        Add check for command shadowing, using shadow_lookup.

        even if expand-file-name or file-attributes throw, eg. because of
        a user interrupt.  Also enable immediate_quit while calling
        re_search, so that matching can be interrupted as well.

2000-10-24  Andrew Innes  <andrewi@gnu.org>

        * regex.c (IMMEDIATE_QUIT_CHECK): New macro, which does QUIT on
        NT-Emacs only.

        * eval.c (internal_condition_case): Comment out abort if

        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.

        * dispextern.h: Add some comments.

        * 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>

        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

        (add_row_entry): New function.
        (scrolling_window): Use data structures allocated with xmalloc and

        hash table; instead, clear used slots only.

        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 (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.

        to stop reading, even if the form read sets point to a different

        * 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.

        ends_in_middle_of_char_p flag.

2000-03-13  Stefan Monnier  <monnier@cs.yale.edu>

        * 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
        variable before the invocation of YMF_PASS_LDFLAGS, in case both
        of them try to use backquotes.

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

        (Qbar, Qcursor_type, outside_cursor): New variables.
        (syms_of_msdos): Intern and staticpro them.
        (dos_ttraw) [__DJGPP__ >= 2, !HAVE_X_WINDOWS]: Save the cursor
        shape used outside Emacs when called for the first time.
        (dos_ttcooked) [__DJGPP__ >= 2, !HAVE_X_WINDOWS]: Restore the

        (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.
        (POP_PATTERN_OP): New macro for re_compile_fastmap.
        (DEBUG_PUSH, DEBUG_POP): Remove.
        (NUM_REG_ITEMS): Remove.
        (NUM_NONREG_ITEMS): Adjust.
        (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
        (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>

        * config.in: Don't depend on __STDC__ for volatile.
        Add POINTER_TYPE, PTR, PROTOTYPES.

        wrong mask when PRIORITIES is specified and detect_coding_XXX()
        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.

        * xterm.c (x_connection_closed) [USE_X_TOOLKIT]: Don't try to
        close the display with XtCloseDisplay.  This caused a bus error
        on OpenWindows.

        * minibuf.c (Fminibuffer_complete): Move point to ZV when input is
