This introduces the predicate frame-initial-p, which uses
struct frame.output_method or struct terminal.type to detect
initial_terminal without relying on its name (bug#80629).
For some prior discussion, see:
https://lists.gnu.org/r/emacs-devel/2019-12/msg00480.htmlhttps://lists.gnu.org/r/emacs-devel/2020-01/msg00120.html
* doc/lispref/frames.texi (Frames): Document frame-initial-p.
(Finding All Frames): Fix grammar.
* etc/NEWS (Lisp Changes in Emacs 31.1): Announce frame-initial-p.
* lisp/desktop.el (desktop--check-dont-save):
* lisp/emacs-lisp/debug.el (debug):
* lisp/frameset.el (frameset-restore):
* lisp/menu-bar.el (menu-bar-update-buffers):
* lisp/xt-mouse.el (turn-on-xterm-mouse-tracking-on-terminal):
Use frame-initial-p instead of checking the "initial_terminal" name.
* lisp/emacs-lisp/byte-opt.el: Mark frame-initial-p as error-free.
* src/pgtkterm.c (pgtk_focus_changed): Use IS_DAEMON in place of
Fdaemonp, thus also accepting a named daemon session.
* src/terminal.c (decode_tty_terminal): Clarify commentary.
(Fframe_initial_p): New function.
(syms_of_terminal): Expose it.
(init_initial_terminal): Update commentary now that
menu-bar-update-buffers uses frame-initial-p (bug#53740).
* test/lisp/xt-mouse-tests.el (with-xterm-mouse-mode): Simulate the
lack of an initial terminal by overriding frame-initial-p now
that turn-on-xterm-mouse-tracking-on-terminal uses it.
* test/src/terminal-tests.el: New file.
* src/xterm.c [!USE_GTK] (x_update_frame_user_time_window): When
replacing _NET_WM_USER_TIME with a new _NET_WM_USER_TIME_WINDOW and
the frame has requested no-focus-on-map, ensure _NET_WM_USER_TIME is
zero also on the new _NET_WM_USER_TIME_WINDOW.
(x_make_frame_visible) [!USE_GTK]: Don't overwrite _NET_WM_USER_TIME
before mapping a frame that has requested no-focus-on-map, and whose
_NET_WM_USER_TIME should thus remain zero (bug#80525).
The fields of the new struct are what the global variables
charset_table, charset_table_size, charset_table_used, and
charset_attributes_table used to be. The struct should make it clearer
that those fields must be kept in sync.
* src/charset.h (struct charset_table): New struct.
(charset_attributes_getter): Adjust accordingly.
* src/charset.c (charset_table): Change type to struct charset_table.
(charset_table_size, charset_table_used, charset_attributes_table):
Moved to the struct.
(Fdefine_charset_internal, Ffind_charset_region, Ffind_charset_string)
(shrink_charset_table, syms_of_charset): Adjust to struct charset_table.
* src/pdumper.c (dump_charset, dump_charset_table): Adjust to struct
charset_table.
Determining the best size for a static array seems difficult; so
allocate it dynamically.
* src/charset.c (CHARSET_TABLE_INIT_SIZE): New constant.
(syms_of_charset): Malloc charset_table here.
(charset_table_init): Removed.
(shrink_charset_table): New function.
(Fclear_charset_maps): Call it.
* src/charset.h (charset_table_init): Removed.
(charset_attributes_getter): Add an assertion.
* src/pdumper.c (dump_charset_table): Assert that charset_table_size ==
charset_table_used.
This simplifies the GC code, as this was the only field in the charset
struct that referenced the GC heap. Without it, we no longer need to
trace the charset_table.
* src/charset.h (struct charset.attributes): Removed.
(charset_attributes_getter): New helper.
(CHARSET_ATTRIBUTES): Use it.
* src/charset.c (charset_attributes_table): New.
(Fdefine_charset_internal): Place attrs in charset_attributes_table.
(syms_of_charset): Initialize charset_attributes_table.
(mark_charset): Deleted.
* src/pdumper.c (dump_charset): Skip attributes field.
* src/lisp.h (mark_charset): Deleted.
* src/alloc.c (garbage_collect): mark_charset no longer needed.
* doc/lispref/windows.texi (Window Sizes):
* src/window.c (Fwindow_body_height, Fwindow_total_height)
(Fwindow_total_width, Fwindow_body_width): Clarify that window
dimensions are returned in canonical columns and lines.
(Bug#80620)
Eliminate an annoying event-loop delay after dropping into an
Emacs window.
* src/nsterm.m: ([EmacsView performDragOperation:]): Kick the
event loop after posting the DRAG_N_DROP_EVENT.
* src/widget.c (EmacsFrameRealize): Assign bit_gravity, and use
the value of NorthWestGravity which matches the GTK3 behavior,
and the general intuition that window's contents should move
with its top-left corner. The result is that the frame is not
blinking during resizing (bug#80369).
* src/xfns.c (x_window) [!USE_X_TOOLKIT]: Change bit_gravity from
StaticGravity to NorthWestGravity as well, to match the others.
Further to bug#80428, they are no longer used since commit of
2018-08-05 "Simplify regex-emacs code by assuming Emacs".
Suggested by Pip Cet <pipcet@protonmail.com>.
* src/conf_post.h [emacs] (RE_TRANSLATE_TYPE): Remove;
no longer used except under lib-src.
[emacs] (RE_TRANSLATE): Remove; redefined in src/regex-emacs.c.
* .dir-locals.el (c-noise-macro-names): Remove ANDROID_EXPORT, which
is no longer used. Add ATTRIBUTE_COLD, ATTRIBUTE_CONST,
ATTRIBUTE_MAY_ALIAS, ATTRIBUTE_NONSTRING, ATTRIBUTE_RETURNS_NONNULL,
EXTERNALLY_VISIBLE, MAYBE_UNUSED, and NODISCARD.
(c-noise-macro-with-parens-names): Also tell cc-mode about some
function-like attribute macros in use (bug#80428).
* src/conf_post.h (RE_TRANSLATE_P): Remove; it is no longer used.
* src/xdisp.c (display_menu_bar): Return immediately if the
menu-bar items were not yet computed. This avoids assertion
violations when this function is called as part of creating a new
frame. (Bug#80603)
Define new functions to manipulate error descriptors and
add support for `signal` to *re*signal a previous error.
* src/eval.c (Fsignal): Make the second arg optional and document
the possibility of passing a whole error descriptor to re-signal it.
(signal_or_quit): Fix a few corner case issues when
DATA is `nil` and ERROR_SYMBOL is an error descriptor.
* lisp/subr.el (error-type-p, error--p, error-type, error-data)
(error-has-type-p, error-slot-value): New function.
* doc/lispref/control.texi (Handling Errors): Prefer "error descriptor"
to "error description". Use the new single-arg call to `signal` to
re-throw an error.
Document `error-type`, `error-data` and `error-slot-value`.
(Error Symbols): Document the new functions `error-type-p` and
`error-has-type-p`.
* src/keyboard.c (kbd_buffer_get_event): Ignore selection-request
events when accessing the frame of an event. Suggested by dick
r. chiang <dick.r.chiang@gmail.com>. (Bug#80558)
Support calls to ns_lisp_to_color or Fns_list_colors in headless
environments where ns_term_init is not called, and calls before
ns_term_init runs.
* src/emacs.c (main): Call ns_init_colors when not in dump mode.
* src/nsfns.m (ns_init_colors): Make public function.
(Fns_list_colors): Remove ns_init_colors call.
* src/nsterm.h: extern ns_init_colors.
* src/frame.c (delete_frame): Call 'get-mru-frame' safely and
with EXCLUDE-FRAME argument set up correctly.
* lisp/frame.el (get-mru-frames, get-mru-frame): Fix doc-strings.
* src/json.c (json_out_string):
Optimise for runs of non-special ASCII chars.
This seems to be a a substantial performance gain for long strings but a
smaller regression for short strings (up to 6 chars or thereabouts,
depending on cpu, compiler, and/or C library). Still likely worth it.
