Don't crash if the file name argument to file-name-case-insensitive-p,
after expansion, doesn't have a parent directory. This occurs
when calling ffap on something that looks like an email address.
* src/fileio.c (Ffile_name_case_insensitive_p): Return nil if no file
or parent directory could be found.
* test/src/fileio-tests.el (fileio-tests--identity-expand-handler)
(fileio--file-name-case-insensitive-p): New test.
* src/xterm.c (x_set_frame_alpha): Don't synchronize while
setting alpha property, and don't ask for the current value of
the opacity property, which is much more expensive than changing
it.
By separating the code paths for append and vconcat, each becomes
simpler and faster.
* src/fns.c (concat_strings): Rename to...
(concat_to_string): ...this.
(concat): Split into concat_to_list and concat_to_vector.
(concat_to_list, concat_to_vector): New, specialised and
streamlined from earlier combined code.
(concat2, concat3, Fappend, Fconcat, Fvconcat): Adjust calls.
This is relevant for bug #56305, and might solve that bug. The code being
removed went into Emacs between 1992 and 1994, and looks to have been a
workaround for switching frames, before the command 'other-frame' had been
written. Nowadays, that code has harmful effects, causing frames' focus to be
redirected at random, sometimes back to the frame itself.
* src/frame.c (do_switch_frame): Remove 53 lines of code.
* src/xterm.c (x_dnd_process_quit): New function.
(x_dnd_begin_drag_and_drop): Use it instead. Also quit if
quit-flag is true immediately after a selection converter is
run.
* lisp/simple.el (primitive-undo): If the visited-modtime of the
indirect buffer's file is bogus, use the modtime of the file
visited by its base buffer.
* src/undo.c (record_first_change): Call
'buffer_visited_file_modtime' with the correct buffer, instead of
always calling 'Fvisited_file_modtime', which returns possibly
bogus values for indirect buffers.
* src/fileio.c (Fset_visited_file_modtime): Signal a meaningful
error for indirect buffers.
(buffer_visited_file_modtime): New function, with implementation
taken from 'Fvisited_file_modtime'.
(Fvisited_file_modtime): Call 'buffer_visited_file_modtime'.
* src/lisp.h: Add prototype for 'buffer_visited_file_modtime'.
(Bug#56397)
* msdos/sedlibmk.inp: Define GL_GNULIB_RAWMEMCHR.
* src/process.c (Fsignal_names): Disable on MS-DOS and use
SIGNUM_BOUND, which is always provided by gnulib.
* src/xterm.c (x_restore_events_after_dnd): New function.
(x_dnd_cleanup_drag_and_drop, x_dnd_begin_drag_and_drop): Use
that instead of manually cleaning up properties and events.
* lisp/x-dnd.el (x-dnd-handle-xdnd): Use correct meaning of "2",
which isn't well documented.
* src/xterm.c (handle_one_xevent): Likewise. Also fix unpacking
of mouse rects.
* src/xterm.c (x_ignore_errors_for_next_request, x_uncatch_errors)
(x_check_errors, x_had_errors_p): Don't call XNextRequest
redundantly. Use NextRequest if it was immediately preceded by
XNextRequest, which updates dpy->request.
* src/xselect.c (Fx_get_local_selection): Check that VALUE has 4
elements, since x_get_local_selection can dump core otherwise.
This pacifies gcc -Wanalyzer-null-dereference, which found the
problem.
* src/xterm.c (x_dnd_do_drop): New function.
(x_dnd_begin_drag_and_drop): Clear new flag.
(handle_one_xevent): Use that function; send drops upon receipt
of pending XdndStatus, to avoid race conditions where we don't
yet know the selected action.
* src/xterm.c (x_connection_closed): Print list of installed
error handlers if not crashing due to an IO error.
(NO_INLINE): Include error serial in error message.
* src/pgtkterm.c (window_state_event): Support values fullheight and
fullwidth for the fullscreen frame-parameter
* doc/lispref/frames.texi (Size Parameters): Document inability to
actively set hullheight/fullwidth for PGTK frames
* configure.ac: Bump GTK version for PGTK
* etc/NEWS: Change GTK version in PGTK announcement
* src/xfaces.c (Finternal_merge_in_global_face)
(gui_supports_face_attributes_p): Only modify local copy of face
attributes when replacing 'reset' pseudo-values with real values.
(Bug#38771)
* doc/lispref/display.texi (Face Attributes):
* etc/NEWS: Document the new pseudo-value 'reset'.
* src/xfaces.c (realize_named_face, lookup_derived_face)
(gui_supports_face_attributes_p, lookup_named_face)
(Finternal_merge_in_global_face, merge_named_face, merge_faces):
Handle the 'reset' pseudo-value of a face's attribute.
(syms_of_xfaces): New symbol 'reset'.
(RESET_P): New macro.
(check_lface_attrs, Finternal_set_lisp_face_attribute): Allow
'reset' as a value of any attribute except ':inherit'.
(Bug#38771)
* src/xfns.c (setup_xi_event_mask, Fx_create_frame): Set
`xi_mask' ourselves if the version of libXi is too old to have
working XIGetSelectedEvents.
* src/xterm.c (x_destroy_window): Free `xi_mask' with xfree in
that case.
* lisp/x-dnd.el (x-dnd-debug-errors): New variable.
(x-dnd-handle-drag-n-drop-event): Bind
`x-fast-protocol-requests' to t if that is off.
* src/xfns.c (Fx_change_window_property):
(Fx_delete_window_property):
* src/xselect.c (Fx_send_client_message, x_send_client_event):
Don't sync to check for errors if fast protocol requests are
enabled.
* src/xterm.c (x_catch_errors_for_lisp, x_check_errors_for_lisp)
(x_uncatch_errors_for_lisp): New functions.
(syms_of_xterm): New variable `x-fast-protocol-requests'.
* src/xterm.h: Update prototypes.
* src/xterm.c (xm_send_drop_message)
(xm_send_top_level_enter_message, xm_send_drag_motion_message)
(xm_send_top_level_leave_message, x_dnd_compute_toplevels)
(x_dnd_send_enter, x_dnd_send_position, x_dnd_send_leave)
(x_dnd_send_drop, handle_one_xevent, x_catch_errors_with_handler)
(x_request_can_fail, x_clean_failable_requests)
(x_ignore_errors_for_next_request, x_stop_ignoring_errors)
(x_uncatch_errors, x_check_errors, x_had_errors_p, x_error_handler)
(frame_set_mouse_pixel_position, x_focus_frame): Record serial
sequences instead of simply the next request when ignoring a
single request. Use XNextRequest instead of NextRequest, since
the latter is unreliable when using Xlib built with XCB.
* src/xterm.h (struct x_failable_request): New struct..
(struct x_display_info): Make failable request variables the
right type.
