* src/data.c (Fkill_local_variable):
* src/buffer.c (buffer_local_value): Use assq_no_quit instead of
Fassoc/Fassq on local_var_alist (bug#53242).
* src/data.c (Flocal_variable_p): Use assq_no_quit instead of
open-coding the search on local_var_alist.
* lisp/frame.el (undelete-frame): New command.
(undelete-frame--handle-delete-frame): New auxiliary function.
(undelete-frame--deleted-frames): New auxiliary variables.
(undelete-frame-mode): New minor mode.
(ctl-x-5-map): Bind the new command.
* etc/NEWS: Document the new command and minor mode.
* src/frame.c (Fdelete_frame): Update docstring, and mention the
minor mode.
* lisp/menu-bar.el (menu-bar-file-menu): Add an entry for the
new command.
* doc/emacs/frames.tex (Frame Commands): Document the new command
and minor mode.
See bug#51883.
* src/xfns.c (setup_xi_event_mask): Set focus masks on both the
shell window and the frame window.
* src/xterm.c (x_detect_focus_change): Enable XI2 focus code on
Xt.
* src/font.c (font_score, font_delete_unmatched): Don't assume
weight, slant, and width properties of the font must be fixnums:
some variable-weight fonts violate that assumption. Reported
by Sean Whitton <spwhitton@spwhitton.name>. This is for builds
with Fontconfig < v2.11.91, for which the fix in
'ftfont_pattern_entity' cannot work. (Bug#52888)
This is considered a temporary fix until the cause of
fringe-overwriting underlines is established.
* src/xterm.c (x_draw_glyph_string): Don't constrain decorations
if the row is a tab or modeline.
Reduce dependency on Haiku internals, by not assuming that
Haiku errno values (which are negative) are neither -1 nor -2.
This removes an #ifdef HAIKU while still maintaining
portability to Haiku.
* src/filelock.c (NEGATIVE_ERRNO, ANOTHER_OWNS_IT, I_OWN_IT):
New constants, which should work regardless of whether
we are on Haiku or B_USE_POSITIVE_POSIX_ERRORS is defined.
(current_lock_owner, lock_if_free, lock_file, unlock_file)
(Ffile_locked_p): Use them, without assuming anything about errno
value sign.
This breaks when x_free_xi_devices is called from a
HierarchyChange event where a master device has been removed or
a slave device has been detached, and it should no longer be
required since we now rely on passive grabs.
* src/xterm.c (x_init_master_valuators): Stop calling
XIUngrabDevice on all devices.
* doc/lispref/display.texi (Face Attributes): Document new
`:position' property of the `:underline' attribute.
* etc/NEWS: Announce new property.
* lisp/cus-face.el (custom-face-attributes): Implement
customization for new face attribute.
* src/dispextern.h (struct face): New fields
`underline_pixels_above_descent_line' and
`underline_at_descent_line_p'.
* src/haikuterm.c (haiku_draw_text_decoration):
* src/nsterm.m (ns_draw_text_decoration):
* src/w32term.c (w32_draw_glyph_string):
* src/xterm.c (x_draw_glyph_string): Respect new face fields.
* src/xfaces.c (realize_gui_face): Handle new `:position'
keyword.
(syms_of_xfaces): New symbol `:position'.
* doc/emacs/haiku.texi (Haiku Basics): Document how X resources
are discovered on Haiku.
* src/haiku_support.cc (class Emacs): Load settings file.
(be_find_setting): New function.
* src/haiku_support.h (be_find_setting): New prototype.
* src/haikuterm.c (get_string_resource): Look in the settings
file if there's nothing in the in-memory resource database.
* src/haiku_support.cc (keysym_from_raw_char): New function.
(DispatchMessage): Map raw character to keysym if applicable.
(be_map_key): Delete function.
* src/haiku_support.h (struct haiku_key_event): Update fields
to hold keysym and character instead.
* src/haikuterm.c (haiku_read_socket): Don't call be_map_key,
and use keysym field if provided instead.
This was found during the investigation surrounding bug#53136,
but is not directly related.
* src/filelock.c (lock_if_free): Explictly test err against -1
or -2, and reverse sign of system errors on Haiku. (No Haiku
error occupies -1 or -2.)
* src/gtkutil.c (xg_im_context_preedit_changed): Set caret
position appropriately.
* src/xfns.c (xg_widget_key_press_event_cb): Ignore modifier
keys.
(xic_preedit_caret_callback, xic_preedit_draw_callback):
Constrain caret position to the string length as well.
* src/xfns.c (xic_preedit_caret_callback):
(xic_preedit_draw_callback): Use `cursor' property correctly.
* src/xterm.c (handle_one_xevent): Stop filtering XI release
events. This caused more problems than it fixed.
* src/xfns.c (xic_preedit_start_callback): Clear caret position.
(xic_preedit_caret_callback): Record new caret position and
announce it.
(xic_preedit_done_callback): Clear caret position.
(xic_preedit_draw_callback): Set caret position appropriately.
* src/gtkutil.c (xg_widget_key_press_cb): Get unicode mapping of
keyval if string doesn't exist.
* src/xterm.c (handle_one_xevent): Fix build without
HAVE_X_I18N.
