1534         actually redrawn.  Make the function static.  Reset

1572         (syns_of_xfns): DEFVAR_LISP it.
1573         (Fx_show_tip): Add parameter TEXT.  Set the tip frame's root
1574         window buffer to *tip* right after creating the frame. Set frame's
1575         window_width.  Use a maximum tooltip size specified by
1576         Vx_max_tooltip_size, if that has valid contents.
1577         (compute_tip_xy): Add parameters WIDTH and HEIGHT.

1667
1668         The following changes remove inverse-video support for terminals
1669         that use a `magic cookie' standout mode.  Due to changes in the
1670         way mode-lines are displayed, such support no longer works
1671         anyway, and it's probable that almost no one uses such terminals
1672         anymore:

1682         Set `costs_set' to true.
1683         (cursor_to, clear_end_of_line): Test `costs_set' instead of
1684         `chars_wasted'.

1708
1709         * editfns.c (text_property_stickiness): Non-rear-non-stickiness

1725
1726         * fontset.c (fs_load_font) [WINDOWSNT && _MSC_VER]: Disable
1727         optimization.  The fontp->encoding array was not being initialized
1728         correctly when compiled with optimizations by MSVC.
1729
1730 2001-10-18  Gerd Moellmann  <gerd@gnu.org>

1740
1741         * w32term.c (w32_encode_char): Get cached codepage from font_info,
1742         rather than working it out by calling w32_codepage_for_font for
1743         every glyph.
1744
1745 2001-10-17  Andrew Innes  <andrewi@gnu.org>
1746
1747         * w32term.c (w32_read_socket): Determine clipping rectangle for
1748         the entire frame, including areas covered by scrollbars and the
1749         menubar.  This avoids internal arguments about whether a frame is
1750         fully obscured or not.
1751
1752 2001-10-17  Gerd Moellmann  <gerd@gnu.org>
1753
1754         * xdisp.c (try_window_id): Undo last change.  Give up if

1756

1758         end if the rest of the window after the window end was already blank.

1785
1786         Avoid the assumption that car and cdr slots of cons cells are
1787         addressable lvalues; this allows for easier experimentation with
1788         other lisp implementations that may not permit such accesses for
1789         various reasons.  Not quite complete -- buffer.c still needs some
1790         work, and w32/mac files need rechecking -- so compile-time

2289
2290         * w32fns.c (x_to_w32_color): Fix argument to alloca.
2291         (w32_load_system_font): Don't believe what GetLanguageFontInfo
2292         says; query codepage info directly to determine if font is double byte.
2293         (x_to_w32_charset): Handle private format for unknown charsets.
2294         Handle wildcards in charset spec, by ignoring them.
2295         (w32_codepage_for_font): Fix argument to alloca.  Don't remove
2296         "*-" prefix from charset.
2297         (x_to_w32_font): Enlarge remainder array for safety.  Specifically
2298         handle the truncated font spec form constructed by font_list_1, so
2299         that we correctly identify the charset fields.  Don't remove "*-"
2300         prefix from charset.

2311 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2312
2313         This handles unknown keysyms better than before.  For example,
2314         after `xmodmap -e 'keysym F5 = ccaron' in a Latin-1 environment,
2315         Emacs formerly completely ignored F5.  With the change, it derives
2316         a key symbol from the name of the X keysym, `ccaron' in this case.
2317         Reported by Martin Buchholz.
2318
2319         * xterm.c (XTread_socket): Return a non_ascii_keystroke for
2320         unknown keysyms.
2321
2322         * keyboard.c (make_lispy_event) [HAVE_X_WINDOWS]: If we know
2323         that EVENT->code isn't a function key, use the keysym's name.
2324
2325 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2326
2327         FOREACH is a macro that should make it easier to loop over Lisp
2328         lists with checks for cycles and proper lists.
2329
2330         * lisp.h (LIST_END_P, FOREACH): New macros.
2331
2332 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2333
2334         On some systems, XtCloseDisplay seems to cause a SIGSEGV when
2335         called for a lost connection.  Prevent dumping core in this case.
2336         Instead print the X error, and exit.  On user request.
2337
2338         * xterm.c (error_msg): New variable.
2339         (x_fatal_error_signal): New function.
2340         (x_connection_closed): Set error_msg.  Install x_fatal_error_signal
2341         as fatal_error_signal_hook around the call to XtCloseDisplay.
2342
2343         * emacs.c (fatal_error_signal_hook): New variable.
2344         (fatal_error_signal): Call that function.
2345
2346 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2347
2348         With this, Emacs prints how much pure storage it will
2349         approximately need in case pure storage overflows while dumping.
2350
2351         * alloc.c (purebeg, pure_size, pure_bytes_used_before_overflow):
2352         New variables.
2353         (init_alloc_once): Initialize new variables.
2354         (PURE_POINTER_P): Use new variables.
2355         (pure_alloc): If pure storage overflows, allocate from the heap.
2356         (check_pure_size): New function.
2357         (Fgarbage_collect): Don't GC if pure storage has overflowed.
2358
2359         * lisp.h (pure_size) [HAVE_SHM]: Declare extern size_t.
2360         (check_pure_size): Add prototype.
2361
2362         * emacs.c (Fdump_emacs_data, Fdump_emacs): Call check_pure_size.
2363
2364 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2365
2366         This adds a post-gc-hook that's run with GC inhibited.
2367         Requested by Francois Pinard.  XEmacs has it.  Added to NEWS.
2368
2369         * alloc.c (Vpost_gc_hook, Qpost_gc_hook): New variables.
2370         (syms_of_alloc): DEFVAR_LISP post-gc-hook, initialize Qpost_gc_hook.
2371         (Fgarbage_collect): Run post-gc-hook.
2372
2373 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2374
2375         This adds `defvaralias' and `indirect-variable'.  Changes not
2376         directly related to this feature are there to gain the same
2377         performance again as before variable aliases.
2378
2379         You must use the SYMBOL_VALUE and SET_SYMBOL_VALUE macros in C
2380         code to get and set symbol values, to take defvaralias into account.
2381
2382         (Note: the new `constant' bit-flag in symbols would make it
2383         possible to define arbitrary read-only variables, e.g. with
2384         `defconst'.)
2385
2386         Documentation is in lispref/variables.texi.  Added to NEWS.
2387
2388         * lisp.h (enum symbol_interned): New enumeration.
2389         (struct Lisp_Symbol): Remove member `obarray', add
2390         `indirect_variable', `constant', and `interned'.
2391         (SYMBOL_INTERNED_P, SYMBOL_INTERNED_IN_INITIAL_OBARRAY_P)
2392         (SYMBOL_CONSTANT_P, SYMBOL_VALUE, SET_SYMBOL_VALUE): New macros.
2393         (indirect_variable): Add prototype.
2394
2395         * print.c (print_preprocess, print_object): Test internedness of
2396         symbols differently.
2397
2398         * lread.c (Fintern, Funintern): Set symbol's interned and constant
2399         bit-fields.
2400         (init_obarray): Likewise for t and nil.
2401
2402         * eval.c Use SYMBOL_VALUE/SET_SYMBOL_VALUE.
2403         (Fdefvaralias): New function.
2404         (specbind): Simplify the test if symbol is a constant.
2405         (syms_of_eval): Defsubr Fdefvaralias.
2406
2407         * data.c: Use SYMBOL_VALUE/SET_SYMBOL_VALUE.
2408         (Qcyclic_variable_indirection): New variable.
2409         (Fkeywordp): Check for internedness differently.
2410         (Fmakunbound): Simplify the test if symbol is a constant.
2411         (indirect_variable, Findirect_variable): New functions.
2412         (swap_in_symval_forwarding): If SYMBOL is an alias, use the
2413         aliased symbol.
2414         (let_shadows_buffer_binding_p): Check for variable aliases.
2415         (set_internal): Simplify the test if SYMBOL is a constant.
2416         If SYMBOL has a buffer-local value and is an alias, use the aliased
2417         symbol instead.
2418         (syms_of_data): Initialize Qcyclic_variable_indirection and defsubr
2419         Sindirect_variable.
2420
2421         * bytecode.c (Fbyte_code) <varref>: Use SYMBOL_VALUE.
2422         (Fbyte_code) <varset>: Simplify the test if symbol's value can be
2423         set directly.
2424
2425         * alloc.c (Fmake_symbol): Adapt to changes of struct Lisp_Symbol.
2426
2427         * abbrev.c, buffer.c, coding.c, fns.c, frame.c, keyboard.c:
2428         * minibuf.c, sunfns.c, w16select.c: Use SYMBOL_VALUE/
2429         SET_SYMBOL_VALUE macros instead of accessing symbol values directly.
2430
2431 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
2432
2433         * Branch for 21.1.
2434
2435 2001-10-03  Miles Bader  <miles@gnu.org>
2436
2437         * callproc.c (syms_of_callproc): Explicitly state in the
2438         documentation for `process-environment' that earlier entries take
2439         precedence over later ones.

2738         have mouse-face, look ``under'' the string for mouse-face from an
2739         overlay.
2740         (fast_find_position): Add parameter STOP.  In the final row, stop

2762         (syms_of_xdisp): Initialize them.
2763         (handle_single_display_prop): Don't change point, bind `object',
2764         `position', and `buffer-position' instead to the object having the
2765         `display' property, position in the object and position in the buffer.

5326         If x_display_info_for_display returns null, don't try to close

5328
5329         * dispnew.c (save_or_restore_current_matrices): Function removed.

5331         (adjust_frame_glyphs_for_frame_redisplay): Use them to save and
5332         restore the frame's current matrix.  Due to the glyph pointer
5333         setup done in adjust_glyph_matrix, there is no easy way to make
5334         saving the current matrix in the desired matrix generally correct,
5335         so don't try it.

5515
5516         * term.c (update_end): Don't check updating_frame; for some reason
5517         this can be 0 sometimes, such as after dismissing a popup menu,

5519
5520 2001-01-05  Gerd Moellmann  <gerd@gnu.org>
5521
5522         * sysdep.c: Don't prototype srandom; it takes an unsigned argument

5557         * window.c (Fdelete_other_windows): Set window's window_end_valid
5558         to nil when changing the window's start.  Don't change the
5559         window's start when its top position hasn't changed.  If we do,
5560         this will set the window's optional_new_start, which act's like a
5561         force_start during redisplay with C-x 1 M-> under particular
5562         circumstances (see report from Per Starback to emacs-pretest-bug
5563         from 2000-12-13.).

5641
5642         * window.c (Frecenter): Handle centering in graphical frames
5643         specially.  Centering on the basis of line counts doesn't work
5644         reliably with variable-height lines.
5645

5885
5886         * xdisp.c (init_from_display_pos): Pop until the iterator's

5923         freeing window matrices.  The flag windows_or_buffers_changed is

5967
5968         * w32term.c (x_update_begin): Regenerate the palette here, rather

5970
5971         * w32xfns.c (select_palette): Avoid calling SelectPalette if
5972         palette is NULL, since this corrupts memory!  Also get

6445         (handle_face_prop, face_before_or_after_it_pos): Use it
6446         to determine the face ``under'' a string.  Let strings inherit

6450
6451         * dispnew.c (adjust_glyph_matrix): Don't reuse a window's current
6452         matrix if the window's left position has changed; we need to
6453         redraw it in this case.
6454

6470         * xterm.c (x_load_font): Don't use the font's max_bounds for
6471         computing the height of the font.  If max_bounds' ascent or
6472         descent are greater than the font's ascent or descent, this means
6473         glyphs overlap, which should be handled now by redisplay.
6474
6475         * window.c (Veven_window_heights): New variable.
6476         (syms_of_window): DEFVAR_LISP it.

6513         * w32term.c (x_produce_glyphs): If a font for a component of
6514         a composition is not found, use 1 pixel dot ascent and 0 dot
6515         descent value to avoid displaying terribly tall empty boxes.
6516         (expose_area): Pass x-coordinate relative to the exposed
6517         area to x_draw_glyphs instead of a window-relative coordinate.

6520
6521         * xdisp.c (next_element_from_ellipsis): Save face before selective

6527         use the right face id when producing spaces at the end of
6528         the line.

6555
6556         * xterm.c (expose_area): Pass x-coordinate relative to the exposed

6558
6559         * fileio.c (auto_save_error): Add parameter ERROR.  Show the
6560         error in the message.
6561
6562         * keyboard.c (Fread_key_sequence): Don't start the busy cursor
6563         timer after having read a key.  It's not good for code reading

6565
6566         * fileio.c (Finsert_file_contents): When VISIT is t, don't

6591
6592         * xterm.c (x_produce_glyphs): If a font for a component of
6593         a composition is not found, use 1 pixel dot ascent and 0 dot
6594         descent value to avoid displaying terribly tall empty boxes.
6595
6596         * ccl.c (stack_idx_of_map_multiple): Don't use C initializier.

6645         positions on the vertical bar and fringes differently for
6646         window-system frames.  Consider some pixels near the vertical bar
6647         as on the bar if the frame doesn't have vertical scroll bars.
6648         Associate positions between mode or header lines with the
6649         right window, the left one.

6673         * xdisp.c (echo_area_display): If cursor is in the echo area, make
6674         sure that the next redisplay displays the minibuffer, so that

6676
6677         * xterm.c: Test USE_TOOLKIT_SCROLL_BARS everywhere with #ifdef and

6745         (verify_interval_modification): Use it instead of signaling
6746         `text-read-only'.  This makes it easier to catch this error
6747         with a breakpoint.:
6748
6749         * xdisp.c (forward_to_next_line_start): Check for newlines,
6750         not end of line, which includes CR.
6751
6752 2000-11-28  Kenichi Handa  <handa@etl.go.jp>
6753
6754         * coding.c (Ffind_coding_systems_region_internal): Be sure to
6755         include no-conversion.
6756

6763
6764         * xdisp.c (forward_to_next_line_start): If already on a newline,
6765         just consume it to avoid unintended skipping over invisible text below.
6766
6767         * keyboard.c (lucid_event_type_list_p): Handle `help-echo',
6768         `vertical-line', `mode-line' and `header-line' events.
6769
6770         * xdisp.c (try_window_id): Avoid starting to display in the middle
6771          of a character, a TAB for instance.  This is easier than to set
6772          up the iterator exactly, and it's not a frequent case, so the
6773          additional effort wouldn't really pay off.
6774
6775 2000-11-26  Andrew Choi  <akochoi@i-cable.com>
6776
6777         * emacs.c (main) [macintosh]: Call syms_of_frame before calling
6778         init_window_once.

6781
6782         * keyboard.c (make_lispy_event) [mouse_wheel, drag_n_drop]:
6783         Args to window_from_coordinates should be pixel coordinates.
6784
6785         * w32fns.c (x_to_w32_font): Do not filter out italic fonts, as new
6786         redisplay handles them properly.
6787
6788 2000-11-25  Miles Bader  <miles@gnu.org>
6789
6790         * indent.c (compute_motion): Keep pos_byte in sync with pos.

6799         clear current matrices. Clear frame when tool bar disappears.
6800         Don't use more lines for the tool-bar than is available.
6801         (x_change_window_heights): New function.
6802
6803 2000-11-24  Gerd Moellmann  <gerd@gnu.org>
6804
6805         * xdisp.c (init_from_display_pos): If POS says we're already after
6806          an overlay string ending at POS, make sure to pop the iterator
6807          because it will be in front of that overlay string.  When POS is
6808          ZV, we've thereby also ``processed'' overlay strings at ZV.
6809
6810         * xfaces.c (lface_from_face_name): Function comment fix.
6811
6812 2000-11-24  Miles Bader  <miles@gnu.org>
6813
6814         * xdisp.c (display_menu_bar, display_mode_line): Change the way we
6815         apply `mode-line-inverse-video' -- zero means force display using
6816         the default face, non-zero means display using the specialized face.
6817         (syms_of_xdisp): `mode-line-inverse-video' defaults to true again.

6822         hard coded `4'.
6823
6824 2000-11-23  Eli Zaretskii  <eliz@is.elta.co.il>
6825
6826         * coding.c (decode_coding_emacs_mule): Fix the case of
6827         CODING_EOL_LF, which used uninitialized value of c.

6843         items accordingly.

6846         Change references to members deleted from struct frame to use the
6847         new ones.
6848
6849         * xdisp.c (update_tool_bar, build_desired_tool_bar_string): Change
6850         references to members deleted from struct frame to use the new ones.
6851
6852         * dispnew.c (update_frame): Do nothing with frame's tool bar items.
6853

6859
6860 2000-11-23  Miles Bader  <miles@gnu.org>
6861
6862         * xdisp.c (display_menu_bar): Or `mode-line-inverse-video' with

6892         * buffer.c (Fkill_buffer): Notice if the buffer to kill is the
6893         sole visible buffer when we're currently in the mini-buffer, and
6894         give up if so.
6895
6896 2000-11-21  Jason Rumney  <jasonr@gnu.org>
6897
6898         * w32select.c (Fw32_set_clipboard_data): Save a copy of what is
6899         put on the clipboard.
6900         (Fw32_get_clipboard_data): Compare data on clipboard with saved
6901         copy of what Emacs last put there. If they are the same, do not
6902         use the clipboard copy to avoid losing data due to coding conversions.
6903

6923
6924         * s/sol2-5.h: Move #undef USE_MMAP_FOR_BUFFERS out of #if 0

6938         (x_send_scroll_bar_event): Store the window in scroll_bar_windows
6939         and store an index in the XClientMessageEvent.  Storing a
6940         Lisp_Object or pointer can fail on a 64 bit system, since X only
6941         transfers 32 bits.
6942         (x_scroll_bar_to_input_event): Get the window from scroll_bar_windows.
6943

6958         unibyte string correctly.
6959

6978
6979         * xterm.h (struct scroll_bar): Members x_widget_low, x_widget_high
6980         removed.
6981         (SCROLL_BAR_X_WIDGET): Get the widget via XtWindowToWidget.
6982         Take the X display as additional argument.
6983         (SET_SCROLL_BAR_X_WIDGET): Store the window of the widget, since
6984         `Widget' is a pointer type that's not easily stored in Lisp_Object
6985         form in a portable way.
6986
6987         * dispnew.c (update_text_area): Fix last change.

7000         when the last current glyph overlaps the glyph to its right.
7001
7002 2000-11-18  Miles Bader  <miles@gnu.org>
7003
7004         * xdisp.c (message_log_check_duplicate): Let "..."-detection match
7005         lines that *end* with "..." too (that's the most common case!).
7006

7008
7009         * xdisp.c (resize_mini_window): Temporarily change to the
7010         mini-window's buffer if necessary.
7011
7012         * xfns.c (Fx_show_tip): Use default y-offset of -10 so that
7013         the tooltip obscures less text under it.
7014
7015 2000-11-17  Gerd Moellmann  <gerd@gnu.org>

7028
7029         * xdisp.c (pos_visible_p): Compute the default character height
7030         differently.
7031

7033
7034         * xdisp.c (pos_visible_p): Handle case that we reach ZV without

7068
7069         * xdisp.c (try_scrolling): Set scroll_max to max of scroll_* args
7070         so setting scroll-step to 1 doesn't defeat scroll-conservatively.
7071         Set amount_to_scroll to max of dx and scroll_step so that
7072         scroll-conservatively doesn't defeat scroll-step>1.
7073         (syms_of_xdisp): Add a hint in scroll-step's docstring to use
7074         scroll-conservatively for line-at-a-time scrolling.
7075
7076 2000-11-14  Gerd Moellmann  <gerd@gnu.org>

7483         (PUSH_FAILURE_POINTER): Don't cast any more.
7484         (POP_FAILURE_REG_OR_COUNT): Remove the cast that strips `const'.
7485         We want GCC to complain, since this piece of code makes

7498         Now also sets the new value (passed in a new argument).
7499         (re_match_2_internal): Use it.
7500         Also, use a new var `reg' of type size_t when looping through regs
7501         rather than reuse the inappropriate `mcnt'.
7502
7503         * keymap.c (where_is_cache, where_is_cache_keymaps): New vars.

7518         (Fpos_visible_in_window_p): Use pos_visible_p to determine
7519         if position is visible and/or fully visible.
7520

7527         * process.c (send_process): If OBJECT is t, it means that the data
7528         is from C string, but we should encode it.  Before calling
7529         setup_raw_text_coding_system, be sure to flush out data by the
7530         previous coding system.

7538         overlay fields.  Use renamed `text_property_stickiness'.
7539         (text_property_stickiness): Renamed from `char_property_stickiness'.
7540         Only check text properties, not overlays.
7541         * textprop.c (get_char_property_and_overlay): New function.
7542         (Fget_char_property): Use it.
7543         * intervals.h (get_char_property_and_overlay): Add declaration.

7553         (where_is_internal_2): Adapt to fewer args for where_is_internal_1.

7559
7560         * keymap.c (fix_submap_inheritance): Use get_keymap_1 on parent_entry
7561         rather than KEYMAPP, to allow EQ to work correctly if parent_entry is
7562         a symbol.
7563
7564 2000-10-24  Andrew Innes  <andrewi@gnu.org>
7565

7567         (directory_files_internal): Use it to ensure closedir is called
7568         even if expand-file-name or file-attributes throw, eg. because of
7569         a user interrupt.  Also enable immediate_quit while calling
7570         re_search, so that matching can be interrupted as well.

7576         (re_match_2_internal): Use IMMEDIATE_QUIT_CHECK instead of QUIT,

7580
7581         * regex.c (regex_compile): Change the way of handling a range from

7596         read-only outside of gmalloc.

9516         a fifth arg specifying how many times the function is been called
9517         in a row, to let it choose temporary buffers appropriately.

9606         one only when the whole source text is consumed.
9607         (decode_coding_string): Handle the case that the output buffer is
9608         too small to decode the whole source text.  Use

9716         box cursor because that's better visible for large images.

10538         When reverting to the `slow' method, try to nicely handle the case
10539         of nested comments by checking that the comment-starter we found
10540         does indeed match the comment-ender.
10541         (scan_sexps_forward, scan_sexps_forward):
10542         Ignore excessive opening parenthesis rather than throwing an error.

10556
10557         * dispnew.c (row_equal_p): Add parameter MOUSE_FACE_P.  If set,
10558         compare the mouse_face_p flags of both rows.

10613         * window.c (Fwindow_list): Reverse list at the end.
10614         (candidate_window_p): Add parameter OWINDOW.  ALL_FRAMES nil

10623         decrement it at the end.
10624

10635         * config.in (HAVE_SOUNDCARD_H): Undef.
10636         (HAVE_SOUND): Define if HAVE_SOUNDCARD_H.
10637         * Makefile.in (LIBSOUND): New variable.
10638         (LIBES): Include it.
10639         * sound.c [HAVE_SOUNDCARD_H]: Include <sys/ioctl.h> and <soundcard.h>.
10640         (DEFAULT_SOUND_DEVICE): Define to "/dev/dsp" if not defined elsewhere.

10661
10662 2000-07-05  Andrew Innes  <andrewi@gnu.org>
10663
10664         * vm-limit.c (check_memory_limits) [REL_ALLOC]: Use real_morecore
10665         when non-NULL instead of __morecore, to take account of buffer
10666         memory.  This also solves a problem with spurious memory warnings
10667         on Windows.
10668
10669         * ralloc.c: Make real_morecore non-static.

10682         (sys_socket): Install socket inheritance bug fix from 20.7.
10683
10684         * alloca.c [emacs]: Include lisp.h (needed by atimer.h included
10685         here via blockinput.h).
10686
10687 2000-07-05  Stefan Monnier  <monnier@cs.yale.edu>
10688
10689         * w32menu.c (w32_menu_display_help):
10690         * xmenu.c (menu_help_callback): Use show_help_echo.
10691
10692         * keyboard.h (show_help_echo): Declare.
10693
10694         * keyboard.c (show_help_echo): New function, extracted from read_char.
10695         Feval its `msg' argument if it's a cons cell.
10696         (read_char): Use it.
10697         (follow_key): Pass `autoload' to get_keyelt.
10698
10699         * xterm.c (note_mode_line_highlight, note_mouse_highlight)
10700         (note_tool_bar_highlight, XTread_socket):
10701         * msdos.c (IT_note_mode_line_highlight, IT_note_mouse_highlight)
10702         (dos_rawgetc):
10703         * w32term.c (note_mode_line_highlight, note_mouse_highlight)
10704         (note_tool_bar_highlight, w32_read_socket):
10705         Do not gratuitously ignore non-string `help-echo' properties.
10706
10707 2000-07-05  Gerd Moellmann  <gerd@gnu.org>
10708
10709         * eval.c (Feval): Put check for interrupt_input_block in #if 0.
10710
10711         * window.c (delete_all_subwindows): Reset Vwindow_list.
10712
10713         * xterm.c (x_append_glyph, x_append_composite_glyph)
10714         (x_produce_image_glyph, x_append_stretch_glyph): Accomodate to
10715         changes in struct glyph starting 1999-12-27.  Some bit-fields of
10716         struct glyph were not set, which made glyphs unequal when compared
10717         with GLYPH_EQUAL_P.  Redisplay outputs such glyphs, and flickering
10718         effects were the result.  This also depended on the contents of
10719         memory returned by xmalloc.  If flickering happens again, activate
10720         the code in clear_glyph_row that's in #if 0.  If the flickering is
10721         gone with that, chances are that it is caused by something similar.
10722
10723         * dispnew.c (clear_glyph_row): Add debug code in #if 0.
10724
10725         * dispextern.h: Add some comments.
10726

10729         in canonical order, and so that frames appear in the list in
10730         the order given by Vframe_list.
10731         (next_window): Reverse the handling of NEXT_P.
10732

10743         (Fother_window): Cleaned up.
10744         (foreach_window): Add a longer "variable argument list".  Let
10745         callback function return 0 to indicate that cycling over windows
10746         should stop.
10747         (foreach_window_1): Likewise.
10748         (freeze_window_start): Return int.
10749         (init_window): New function.
10750         (syms_of_window): Staticpro Vwindow_list and defsubr Swindow_list.
10751
10752         * emacs.c (handle_USR1_signal, handle_USR2_signal) Clear
10753         input_event with bzero.
10754         (main): Call init_window.
10755
10756         * keymap.c (get_keyelt): Temporarily inhibit GC while evaluating
10757         a menu filter.

10769         composition property value a copy.
10770
10771 2000-07-03  Gerd Moellmann  <gerd@gnu.org>
10772
10773         * m/macppc.h (LINKER, LD_SWITCH_MACHINE) [LINUX]: Define.
10774
10775         * fns.c (sweep_weak_table): Mark only objects that are not
10776         marked already.
10777
10778         * frame.c (next_frame, prev_frame): If MINIBUF is a window,
10779         include those frames as candidates which have their focus
10780         redirected to the minibuffer frame.
10781
10782 2000-07-03  Stefan Monnier  <monnier@cs.yale.edu>
10783
10784         * fns.c (Fputhash): Return `value' rather than nil.
10785
10786 2000-06-30  Gerd Moellmann  <gerd@gnu.org>
10787
10788         * frame.c (next_frame): Don't check focus redirection in case
10789         MINIBUF is a window.  Doing so excludes frames using MINIBUF
10790         unless their focus is redirected, which contradicts the
10791         specification of next-frame, and leads to infinite loops in
10792         certain situations when cycling through windows with next-window.
10793

10812         holding them in local variables.  Use a larger hash table whose
10813         size depends on glyph matrix sizes.  Don't use bzero to clear the
10814         hash table; instead, clear used slots only.
10815
10816         * fns.c (next_almost_prime): Make it externally visible.
10817
10818         * lisp.h (next_almost_prime): Add prototype.

10827         (moved to osf5-0.h).
10828         [!NOT_C_CODE]: Protect string.h stuff.
10829
10830         * s/osf5-0.h (C_SWITCH_SYSTEM, WAIT_USE_INT, SYS_SIGLIST_DECLARED)

10851         * xfns.c (x_window) [!USE_XIM]: Don't call create_frame_ic.

11239         before calling setup_echo_area_for_printing because that
11240         function does something useful even when message_buf_print is
11241         already set.
11242
11243         * xdisp.c (message_truncate_lines, Qmessage_truncate_lines):

11287
11288 2000-06-13  Eli Zaretskii  <eliz@is.elta.co.il>

11364
11365         * xterm.c (XTread_socket) <FocusIn>: Queue a FOCUS_IN_EVENT which
11366         will be translated to a switch-frame event when reading the
11367         event queue.  This is necessary because Emacs otherwise won't
11368         perform a switch-frame to a new frame until some other event, for
11369         example a keystroke event, forces it to do so.  This has various
11370         effects, one visible being that the cursor of a frame created with
11371         C-x 5 2 or switched to with a window manager key binding like
11372         A-TAB stays hollow because selected_window isn't on the newly

11374

11382
11383 2000-06-08  Kenichi Handa  <handa@etl.go.jp>

11393         (Fmove_to_window_line): Use displayed_window_lines to determine
11394         the number of lines to move, instead of using the window's height.

11396         * lread.c (readevalloop): If READCHARFUN sets point to ZV, arrange
11397         to stop reading, even if the form read sets point to a different
11398         value when evaluated.
11399
11400         * xdisp.c (display_line): Fix code deciding in which line to

11413         (dump_glyph_row): Print values of new flags.
11414         (redisplay_window) <cursor movement in unchanged window>: When

11416         row, don't place the cursor in the next row if the cursor row ends
11417         in the middle of a character or at ZV.

11423         ends_in_middle_of_char_p flag.

11425
11426         * term.c (append_glyph): Revert change of 2000-06-06.
11427
11428         * xdisp.c (display_line): Revert change of 2000-06-06.  Treat
11429         padding glyph not fitting on line as whole character not
11430         fitting on line.
11431
11432         * xterm.c (x_produce_glyphs): Don't xassert `it->descent > 0';
11433         this isn't true for images with `:ascent 100'.

12576         (SET_INTERVAL_OBJECT): Don't explicitly compare the object with
12577         zero, instead see whether it's an integer object, since they can't

12599         (XSET) [!NO_UNION_TYPE]: Set the value field first, then the type
12600         field, to better cope with ENABLE_CHECKING and calls that modify a

12609         AFTER_POTENTIAL_GC calls around calls to functions that can
12610         signal an error and thus invoke the debugger.

12647         (PATUNFETCH): Remove.
12648         (regex_compile): Rely on PATFETCH to do most of the multibyte magic.
12649         When writing a char, write it directly into the pattern buffer rather
12650         than going needlessly through a temp char-array.
12651         (re_match_2_internal): Similarly, rely on RE_STRING_CHAR to do the
12652         multibyte magic and remove the useless `#ifdef emacs'.
12653         (bcmp_translate): Don't compare as multibyte chars when in a unibyte

12664         non-union-type versions of XMARK and friends here, because XMARK

12666         defined.
12667         (make_number): Define as a function if it's not defined as a macro.

12700         (handle_fontified_prop, add_to_log): Pass int, not Lisp_Object, as
12701         count arg to variable-arg routines like Frun_hook_with_args and
12702         Fformat.
12703         (back_to_previous_visible_line_start)
12704         (build_desired_tool_bar_string): Pass Lisp_Object, not int, to

12717         (Fbitmap_spec_p): Use XINT to get numeric value of height.
12718         (lface_hash): Apply XFASTINT to lisp values before folding in.

12785         interval pointer and Lisp_Object; add new bitfield to use as
12786         discriminant.  Change other flag fields to bitfields.
12787         (CHECK): New macro for consistency checking.  If ENABLE_CHECKING
12788         is defined and the supplied test fails, print a message and abort.

12790
12791         * intervals.h (NULL_INTERVAL_P): Now applies only to real interval

12821
12822         * regex.c (analyse_first): New function obtained by ripping out most
12823         of re_compile_fastmap and generalizing it a little bit so that it
12824         can also just return whether a given (sub)pattern can match the empty
12825         string or not.
12826         (regex_compile): Use `analyse_first' to decide whether the loop-check
12827         needs to be done or not for *, +, *? and +? (the loop check is costly
12828         for non-greedy repetition).
12829         (re_compile_fastmap): Delegate the actual work to `analyse_first'.

12842         (PATFETCH): Always define.
12843         (regex_compile): Use lookahead rather than PATUNFETCH (for repetition
12844         operators, char classes, shy-groups and intervals).
12845         Optimize special cases of intervals so as to only use succeed_n and
12846         jump_n when really needed.
12847         (re_compile_fastmap): Simplify handling of jump_n and succeed_n now
12848         that we don't have to handle the special cases any more.

13454 2000-03-12  Eli Zaretskii  <eliz@is.elta.co.il>
13455
13456         * msdos.c (vga_installed): New function, code moved from
13457         dos_set_window_size.
13458         (Qbar, Qcursor_type, outside_cursor): New variables.
13459         (syms_of_msdos): Intern and staticpro them.
13460         (dos_ttraw) [__DJGPP__ >= 2, !HAVE_X_WINDOWS]: Save the cursor
13461         shape used outside Emacs when called for the first time.
13462         (dos_ttcooked) [__DJGPP__ >= 2, !HAVE_X_WINDOWS]: Restore the

13464         (msdos_set_cursor_shape, IT_set_cursor_type): New functions.
13465         (IT_frame_up_to_date): Call IT_set_cursor_type, in case the cursor
13466         type has changed.
13467         (IT_set_frame_parameters): Call IT_set_cursor_type if the frame
13468         parameters specify the cursor.  Make qreverse a global

13475 2000-03-08  Stefan Monnier  <monnier@cs.yale.edu>
13476
13477         This is a big redesign of failure-stack and register handling, prompted
13478         by bugs revealed when trying to add shy-groups.  Overall, what happened
13479         is that loops are now structured a little differently, groups can be
13480         shy and the code is a little simpler.
13481
13482         * regex.h: Update the copyright.
13483         (RE_SHY_GROUPS): New value.
13484         (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
13485         (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
13486
13487         * regex.c (enum re_opcode_t): Remove jump_past_alt,
13488         maybe_pop_jump, push_dummy_failure and dumy_failure_jump.  Add
13489         on_failure_jump_(exclusive, loop and smart).  Also fix the comment
13490         for (start|stop)_memory since they now only take one argument (the
13491         second has becomes unnecessary).
13492         (print_partial_compiled_pattern): Adjust for changes in re_opcode_t.
13493         (print_compiled_pattern): Use %ld to printf long ints and flush to
13494         make debugging a little easier.
13495         (union fail_stack_elt): Make the integer unsigned.
13496         (struct fail_stack_type): Add a `frame' element.
13497         (INIT_FAIL_STACK): Init `frame' as well.
13498         (POP_PATTERN_OP): New macro for re_compile_fastmap.
13499         (DEBUG_PUSH, DEBUG_POP): Remove.
13500         (NUM_REG_ITEMS): Remove.
13501         (NUM_NONREG_ITEMS): Adjust.
13502         (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
13503         (TOP_FAILURE_HANDLE): New macros for the cycle detection.
13504         (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
13505         (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP):
13506         New macros.
13507         (PUSH_FAILURE_POINT): Don't push registers any more.  The pattern
13508         address pushed is not the destination of the jump but the source
13509         of it instead.
13510         (NUM_FAILURE_ITEMS): Remove.
13511         (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
13512         registers before the actual failure point).  Don't hardcode any
13513         meaning for str==NULL anymore.
13514         (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
13515         (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
13516         Remove.
13517         (REG_UNSET_VALUE): Use NULL (why not?).
13518         (compile_range): Remove declaration since it doesn't exist.
13519         (struct compile_stack_elt_t): Remove inner_group_offset.
13520         (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
13521         (regex_grow_registers): Remove dead code.
13522         (FIXUP_ALT_JUMP): New macro.
13523         (regex_compile): Add shy-groups Change loops to use
13524         on_failure_jump_smart&jump instead of
13525         on_failure_jump&maybe_pop_jump.  Change + loops to eliminate the
13526         initial (dummy_failure_)jump.  Remove c1_base (looks like unused
13527         variable to me).  Use `jump' instead of `jump_past_alt' and don't
13528         bother with push_dummy_failure in alternatives since it is now
13529         unnecessary.  Use FIXUP_ALT_JUMP.  Eliminate a useless `#ifdef
13530         emacs' for (re)allocating the stack.
13531         (re_compile_fastmap): Remove dead variables i and num_regs.  Exit
13532         from loop when bufp->can_be_null rather than jumping to `done'.
13533         Avoid jumping backwards so as to ensure termination.  Use
13534         PATTERN_STACK_EMPTY and POP_PATTERN_OP.  Improved handling of
13535         backreferences.  Remove dead code in handling of `anychar'.
13536         (skip_noops, mutually_exclusive_p): New functions taken from the
13537         handling of `maybe_pop_jump' in re_match_2_internal.  Slightly
13538         improve mutually_exclusive_p to handle ".+\n".
13539         (lowest_active_reg, highest_active_reg)
13540         (NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
13541         (re_match_2_internal): Use %p instead of 0x%x when printf'ing
13542         ptrs.  Don't SET_REGS_MATCHED anymore.  Remove many dead
13543         variables.  Push register (in `start_memory') on the stack rather
13544         than storing it in old_reg(start|end).  Remove the cycle detection
13545         from `stop_memory', replaced by the use of on_failure_jump_loop
13546         for greedy loops.  Add code for the new on_failure_jump_<foo>.
13547         Remove ad-hoc code in `on_failure_jump' to push more registers in
13548         the case of a loop.  Take out code from `maybe_pop_jump' into
13549         separate functions and adapt it to the semantics of
13550         `on_failure_jump_smart'.  Remove jump_past_alt, dummy_failure_jump
13551         and push_dummy_failure.  Remove dummy_failure handling and
13552         handling of `failures to jump to on_failure_jump' (this last one
13553         was already dead code, it seems).
13554         (group_match_null_string_p, alt_match_null_string_p)
13555         (common_op_match_null_string_p): Remove.
13556
13557 2000-03-08  Dave Love  <fx@gnu.org>

13592         wrong mask when PRIORITIES is specified and detect_coding_XXX()
13593         returns a mask not set in PRIORITIES.
13594         (detect_eol_type_in_2_octet_form): New function.
13595         (detect_eol): selects detect_eol_type_XXX to call according to
