| * Prevent rare freeze on Android 4.2 through 4.4Po Lu2025-02-281-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | * src/android.c (android_run_select_thread, android_init_events) (android_select): Enable self-pipes on all Android versions <= 21. The Android C library provides a functioning pselect on these systems, but it does not apply the signal mask atomically. (android_run_select_thread): Correct typo. This never produced any adverse consequences, as the relevant signals would already have been blocked by `setupSystemThread'. Do not merge to master.
| * ; * src/keymap.c: Fix last change (bug#75219).Eli Zaretskii2025-02-281-1/+1

| | | | | | | | | | | | | | | | * src/keymap.c (Fcurrent_active_maps): For clicks on mode-line and header-line, always override the keymaps at buffer position. (Bug#75219) (cherry picked from commit c41ea047a434710c4b7bc8280695c83fbe5fff35)
* | Fix redisplay of tab bar when its text properties changeEli Zaretskii2025-03-061-1/+4
| | | | | | | | | | * src/xdisp.c (update_tab_bar): Use 'equal-including-properties' to compare previous with the current tab-bar items. (Bug#76760)

* | Make Emacs buildable with -std=c11.Philipp Stephani2025-03-041-1/+1
| | | | | | | | | | | | | | | | | | With -std=c11, GCC doesn't recognize 'asm' as a keyword, see https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html and https://gcc.gnu.org/onlinedocs/gcc/Alternate-Keywords.html. Use __asm__ instead. * src/lisp.h (flush_stack_call_func): Use __asm__ instead of asm.
* | Add ns-click-through option to control activation click handlingDaniel Colascione2025-03-041-1/+16
| | | | | | | | | | | | | | | | | | | | * src/nsterm.m (acceptsFirstMouse): Use ns_click_through variable instead of always returning YES. (syms_of_nsterm): Define ns-click-through variable. * lisp/cus-start.el: Add customization definition for ns-click-through. * etc/NEWS: Document the new option.
* | Fix 'etc/DOC' for a few functions/variablesEli Zaretskii2025-03-043-3/+3

The extra blank was preventing 'make-docfile' from recognizing the functions and variables and extracting their documentation to 'etc/DOC'. (Bug#76722)

* | Support colored stipples on Cocoa NS (Bug#73384)Ben Simms2025-03-043-1/+106
| | | | | | | | | | | | | | | | | | | | | | | | On Cocoa builds of NS Emacs, stipples are now rendered using masked CGImages instead of patterned NSColors so that stipples now render with color. * src/nsimage.m ([EmacsImage stippleMask:]): Use a CGImageMask to store the stipple mask when building for Cocoa. * src/nsterm.m (ns_maybe_dumpglyphs_background): Perform a masked fill to draw stipples when building for Cocoa. (ns_draw_stretch_glyph_string): Perform a masked fill to draw stipples when building for Cocoa.
* | Revert “Avoid some union buffered_input_event uses”Paul Eggert2025-03-036-690/+630
| | | | | | | | | | | | | | | | | | | | | | | | Revert my commit 29a9fd4f4ba17822eca0f00c2037da3868bd874e and the following commit 1ec0889e7b786d79351cee3ed4964d82295f059f. This fixes a bug where ‘emacs -nw’ would sometimes freeze when Emacs is configured with ‘--with-pgtk --enable-link-time-optimization --disable-gc-mark-trace’ on GNU/Linux x86-64 (Bug#76729). As it is not yet clear whether this freeze is due to an Emacs bug that I introduced, or due to GCC bug 117423 <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117423>, play it safe for now and revert to the previous state.

* | Avoid some union buffered_input_event usesPaul Eggert2025-03-036-630/+686
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simplify by using separate local vars for struct input_event and struct selection_input_event, rather than a single local var that is the union of the two. This makes the code easier to follow by the human reader, and should help avoid GCC bug 117423 <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117423> and therefore work around Emacs bug 76559 <https://bugs.gnu.org/76559>. * src/androidterm.c (handle_one_android_event): * src/gtkutil.c (xg_widget_key_press_event_cb): * src/pgtkterm.c (evq_flush): * src/xterm.c (handle_one_xevent): Use struct input_event and kbd_buffer_store_event_hold, or struct selection_input_event and kbd_buffer_store_selection_event_hold, rather than union buffered_input_event and union buffered_input_event. * src/keyboard.c (beware_long_paste, maybe_quit_while_no_input): New functions, broken out from kbd_buffer_store_buffered_event. (kbd_buffer_store_event_hold): Define here, with a simplified version of the body of the old kbd_buffer_store_buffered_event, rather than defining in keyboard.h. Specialize to struct input_event. (kbd_buffer_store_selection_event_hold): New function; it is a simplified version of the old kbd_buffer_store_buffered_event, specialized to struct selection_input_event. (is_ignored_event_kind): Accept enum event_kind instead of union buffered_input_event. All callers changed. * src/keyboard.h (kbd_buffer_store_event_hold): Remove definition, as keyboard.c now defines it. * src/pgtkterm.c (evq_grow_if_needed): New function. (evq_enqueue, evq_selection_enqueue): Two functions now, not one. Args are now struct input_event const * or struct selection_input_event const *, not union buffered_input_event *. All callers changed. This lets us simplify the callers so that they need not use the union.
* | Pacify GCC in pgtkselect malloc alignmentPaul Eggert2025-03-021-8/+16

* | ; Grammar fixes for "native-compiled"Stefan Kangas2025-02-284-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Prefer "native-compiled" to "native compiled". The adjective "native-compiled" with the hyphen is generally more consistent with the typical pattern in English, especially when the compound modifies a noun (e.g., "native-compiled code"). 2. Prefer "natively compiled" to "natively-compiled". The adverb "natively" modifies "compiled", and it is standard not to hyphenate an adverb + adjective combination when the adverb ends in -ly (e.g., "code that is natively compiled"). For example, note that we say "high-speed internet" but "highly performant code". * Makefile.in (dest): * configure.ac (HAVE_NATIVE_COMP): * doc/emacs/building.texi (Lisp Libraries): * doc/lispref/compile.texi (Native Compilation) (Native-Compilation Functions, Native-Compilation Variables): * doc/lispref/functions.texi (What Is a Function, Declare Form): * doc/lispref/loading.texi (How Programs Do Loading, Library Search): * etc/NEWS: * etc/NEWS.28: * etc/NEWS.29: * etc/NEWS.30: * lisp/emacs-lisp/comp-common.el (native-comp-never-optimize-functions) (comp-function-type-spec): * lisp/emacs-lisp/comp-cstr.el: * lisp/subr.el (locate-eln-file): * src/comp.c (SETJMP_NAME, syms_of_comp): * src/data.c (Fsubrp, Fnative_comp_function_p, Fsubr_native_lambda_list): * src/lread.c (Fload): * src/pdumper.c (dump_do_dump_relocation): * test/src/comp-tests.el (lambda-return2): Avoid grammatically incorrect variations on "natively compiled" and "native-compiled".

* | Lift widget functions from C to LispStefan Kangas2025-02-281-61/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the mid-1990s, these functions were moved from Lisp to C to "improve performance". However, Moore's Law, and perhaps other improvements too, has made this rationale irrelevant. On this machine, with --native-compilation=no, I observed only a slight ~4% performance difference. For example, displaying a buffer full of widgets (e.g., 'M-x customize RET browse-url RET') takes 4ms here, meaning the performance gap is under 0.1ms. Even on less powerful machines, this difference would remain imperceptible. Given this, let's lift these functions back to to Lisp, which offers the usual benefits. We already have solid test coverage, but let's add a more focused test for 'widget-get' and 'widget-put' to be thorough. * lisp/wid-edit.el (widget-put, widget-get, widget-apply): Move to Lisp from... * src/fns.c (Fwidget_put, Fwidget_get, Fwidget_apply): ...here. (syms_of_fns): Remove defsubrs for the above functions. * test/lisp/wid-edit-tests.el (widget-test-editable-field-widget-get/put): New test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/android.c (struct android_thread_event_queue): New structure. Move global pselect arguments, mutexes, and semaphores, and pipes here. (struct android_event_queue) <select_mutex, select_thread>: Remove to the above-named struct. (android_init_thread_events, android_finalize_thread_events) (android_get_poll_thread): New functions. (android_run_select_thread): Accept a set of mutexes and thread-local data as the first argument, and operate with them rather than globals. (android_handle_sigusr1): Rename to `android_handle_poll_signal'. Set thread-specific cancellation indicator. (android_init_events): Properly abort after a fatal condition. Enable interruptible polling on Android 5.1 and later, not 4.2. (android_select): Never check for queries here, but in thread_select, if threads are enabled. Adapt to per-thread polling threads and only enable interruptible polling on Android 5.1 and later. (android_before_select): New function. * src/android.h (android_before_select): New declaration. * src/thread.c (thread_select): Call `android_before_select' before the global lock is released.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous approach would incorrectly invalidate the returned module values if another non-local exit occurred while dealing with a non-local exit.

Instead, allocate the values from the usual environment storage, and return statically-allocated objects if that fails. * src/emacs-module.c (struct emacs_env_private): Turn non-local exit symbol and data into normal Lisp objects. (initialize_environment): Initialize them. (mark_module_environment): Prevent them from being garbage-collected. (module_signal_or_throw, module_non_local_exit_signal_1) (module_non_local_exit_throw_1): Adapt uses. (value_to_lisp): No longer scan for them with module assertions enabled. (module_out_of_memory_signal, module_out_of_memory_data): New statically-allocated module values to return in case of allocation failure. (syms_of_module): Initialize them.
