* Fix some C symbol extern visibilityPaul Eggert2025-12-081-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make some C symbols static if they don’t need to be extern. Also, remove a couple of functions that were discovered to be unused as a result of this process, and mark two extern functions intended to be usable from GDB. * src/buffer.c (previous_overlay_change): * src/composite.c (composition_lisp_table): * src/fileio.c (file_name_directory): * src/frame.c (check_tty): * src/insdel.c (adjust_markers_for_insert): * src/keyboard.c (unread_switch_frame, read_char) (requeued_events_pending_p): * src/sysdep.c (renameat_noreplace) [!HAVE_ANDROID]: * src/textconv.c (get_conversion_field) [!HAVE_ANDROID]: * src/treesit.c (TREESIT_BOB_LINECOL, TREESIT_TS_POINT_1_0) (treesit_buf_tracks_linecol_p, make_treesit_parser) (make_treesit_node): * src/xdisp.c (x_y_to_hpos_vpos): * src/xfaces.c (load_color) [!MSDOS]: * src/xfns.c (x_real_pos_and_offsets): * src/xterm.c (x_dnd_do_unsupported_drop): Now static. Move up if necessary. * src/coding.c (utf8_string_p): * src/keyboard.c (detect_input_pending_ignore_squeezables): Remove; unused. * src/frame.c (gui_set_alpha): * src/textconv.c (start_batch_edit, end_batch_edit, commit_text) (finish_composing_text, set_composing_text) (set_composing_region, textconv_set_point_and_mark) (delete_surrounding_text, request_point_update) (textconv_barrier, replace_text, get_extracted_text) (get_surrounding_text): * src/xdisp.c (gui_union_rectangles): * src/xterm.c (xi_frame_selected_for): Define only if needed. * src/treesit.c (treesit_debug_print_parser_list) (treesit_debug_print_linecol): Declare EXTERNALLY_VISIBLE. * src/xdisp.c (x_y_to_column_row): New function, defined only if needed. All external callers to x_y_to_hpos_vpos changed.
* Fix handling of visibility on tty frames (Bug#76031)Martin Rudalics2025-02-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/frame.h (FRAME_REDISPLAY_P): Remove. Use the new function frame_redisplay_p instead. Extern frame_redisplay_p. * src/frame.c (frame_redisplay_p): New function to replace FRAME_REDISPLAY_P macro. (make_terminal_frame): Don't tinker with frame visibility and don't make the new frame the terminal's top frame. (do_switch_frame): Make sure frame switched to and any of its ancestors are visible. Don't reset the visibility of other frames. (other_frames): Do not assume tty frames are by default visible. (Fmake_frame_invisible): When making the selected tty frame invisible, explicitly select the next visible frame. * src/dispnew.c (Fredraw_display): Use frame_redisplay_p instead of FRAME_REDISPLAY_P. * src/xdisp.c (clear_garbaged_frames, echo_area_display) (prepare_menu_bars, redisplay_internal, display_and_set_cursor) (gui_clear_cursor): Use frame_redisplay_p instead of FRAME_REDISPLAY_P. * src/keyboard.c (tty_read_avail_input): When storing an event and the selected frame is a child frame whose root is its terminal's top frame, set the frame_or_window slot to the child frame since otherwise the next switch frame event will select the top frame instead.
* Update copyright year to 2025Paul Eggert2025-01-011-1/+1

* On X, avoid reporting unrepresentable touch IDs to LispPo Lu2024-06-011-6/+9
| | | | | | | | | | | * src/xterm.c (xi_link_touch_point): Assign a Lisp-representable identifier to the new touch point and return the same. (xi_unlink_touch_point): New arg LOCAL_DETAIL. Return such an identifier if there is a matching touch point record. (handle_one_xevent): Adjust as is proper. * src/xterm.h (struct xi_touch_point_t) <local_detail>: New field. Reorder fields for alignment.
* Pacify gcc -Wmissing-variable-declarationsPaul Eggert2024-05-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This is a new warning diagnostic in GCC 14. * lib-src/etags.c (mercury_heuristics_ratio): * src/pgtkselect.c, src/xselect.c (selection_request_stack): * src/xselect.c (outstanding_transfers): * src/xterm.c (pending_selection_requests) (x_dnd_waiting_for_motif_finish_display): Now static. * lib-src/make-docfile.c (close_emacs_globals): Arrange for lispsym to be declared with extern first, when compiling lread.c. * src/alloc.c (gdb_make_enums_visible) [__GNUC__]: * src/emacs.c (RCS_Id): * src/keyboard.c (stop_character): * src/print.c (print_output_debug_flag): Now declared with extern first. * src/lisp.h (DEFINE_GDB_SYMBOL_BEGIN) [MAIN_PROGRAM]: Arrange for ID to be declared extern first. * src/lisp.h (garbage_collection_inhibited): * src/xterm.h (x_frame_parm_handlers): Declare here, so that its interface is properly checked. Other decls removed.
* Pacify GCC 14 -Wnull-dereferencePaul Eggert2024-04-301-0/+2
| | | | | | * src/xterm.c (x_dpyinfo): New function, which acts like x_display_info_for_display except it always returns nonnull. This simplifies callers and pacifies GCC 14. All callers changed.
* Be more systematic about parens in C source codePaul Eggert2024-01-201-3/+3
| | | | | | | | | Be more systematic about putting space before paren in calls, and in avoiding unnecessary parentheses in macros. This was partly inspired by my wading through gcc -E output while debugging something else, and seeing too many parens. This patch does not change the generated .o files on my platform.

Also catch some mistakes found. Fetch all kinds of key names as well. (x_create_special_window): New function. (x_term_init, x_delete_display): Ask for all key names. Also, passively monitor selections that are given to `x-selection-exists-p' during redisplay, so we do not have to ask the server about them upon each redisplay. (syms_of_xterm): New variable `x-fast-selection-list'. * src/xterm.h (struct x_monitored_selection): New structure. (X_INVALID_WINDOW): New define.

* Fix multiple sources of flicker under XPo Lu2022-10-161-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | Fix three kinds of flicker. The first is if you do: (while t (sit-for 1) (redraw-display)) and press a key, the frame will turn blank until you C-g. The second is where handling async input happens in the middle of drawing and causes a buffer flip to happen. The third is where unmapping the hourglass window causes exposures. * src/dispnew.c (redraw_frame): Garbage the frame if it is a window system frame. * src/xterm.c (x_update_begin): Clear complete flag. (x_flip_and_flush, XTframe_up_to_date): Set complete flag. (x_show_hourglass): Fix hourglass window class. (flush_dirty_back_buffer_on): Rename to x_flush_dirty_back_buffer_on. (x_flush_dirty_back_buffer_on): Check if the frame is complete before trying to flip. (handle_one_xevent): Flush frames in a more detailed fashion. * src/xterm.h (struct x_output): New flag `complete'. (FRAME_X_COMPLETE_P): New macro.
* Fix coding systems used for X input methodsPo Lu2022-10-031-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | * doc/emacs/mule.texi (International): Refer to X Coding as well. (Communication Coding): Document that locale-coding-system is not always used on X to decode keyboard input. (X Coding): New node. * etc/NEWS: Announce change to input method coding resolution. * lisp/term/x-win.el (x-get-input-coding-system): New function. * src/coding.c (syms_of_coding): Update doc string of locale-coding-system. * src/xfns.c (struct x_xim_text_conversion_data) (x_xim_text_to_utf8_unix_1, x_xim_text_to_utf8_unix_2) (x_xim_text_to_utf8_unix): Accept dpyinfo. Use the coding system specified inside if possible. (xic_preedit_draw_callback): Pass dpyinfo. * src/xterm.c (handle_one_xevent): Use XIM coding system for IM input. (xim_open_dpy): Try to determine the input method coding system. (mark_xterm): Mark `xim_coding'. (syms_of_xterm): New variable `x-input-coding-system'. * src/xterm.h (struct x_display_info): New field `xim_coding'. (FRAME_X_XIM_CODING): New macro.
* Optimize coordinate translation during event handlingPo Lu2022-09-271-0/+9
| | | | | | | | | | | | | | | | | | | These changes noticeably improve turning the mouse wheel on top of scroll bars etc over slow network connections. * src/xterm.c (x_dnd_note_self_position, x_dnd_note_self_wheel) (x_dnd_note_self_drop): Use x_translate_coordinates. (x_compute_root_window_offset): New function for calculating and caching root window offsets of edit window. (x_translate_coordinates): New function. Use cached values whenever possible. (xi_compute_root_window_offset) (xi_compute_root_window_offset_pinch): New wrappers for XI2 events. (x_construct_mouse_click, handle_one_xevent): Use x_translate_coordinates wherever appropriate. * src/xterm.h (struct x_output): New fields for keeping track of the root window offset of the edit window.
* Reduce complexity of scroll bar window protection codePo Lu2022-09-241-9/+0
| | | | | | | | | | | | | | | | | | | | It turns out my previous theories of why ClientMessages were generated were wrong, and they are just generated so we can set finish to X_EVENT_GOTO_OUT to have them delivered immediately. This allows for the code to be simplified greatly, by not unpacking pointers to the raw window into the client messages. * src/xterm.c (x_unprotect_window_for_callback): Return the window removed from the queue, or nil if none. (x_scroll_bar_to_input_event) (x_horizontal_scroll_bar_to_input_event): Use window provided by x_unprotect_window_for_callback. (handle_one_xevent): Pass dpyinfo to functions that need it. (x_free_frame_resources): Remove "first scroll bar request" code. * src/xterm.h (struct x_display_info): Likewise.
* Fix more toolkit scroll bar window protection issuesPo Lu2022-09-231-0/+9

| | | | | | | | | * src/xfns.c (x_set_use_frame_synchronization): Announce that we do not want the compositor to unredirect the frame while fullscreen. * src/xterm.c (x_atom_refs): New atom `_NET_WM_BYPASS_COMPOSITOR'. * src/xterm.h (struct x_display_info): Likewise.
* Prevent crashes when embedding Emacs in a nonexistent parentPo Lu2022-09-021-2/+2
| | | | | | | | | | | | * src/xfns.c (x_window, Fx_create_frame): Handle X errors while trying to reparent the frame onto an explicitly specified parent. * src/xterm.c (handle_one_xevent): Handle unparenting embedded windows correctly. This only works if the embedder is aware of the fixes extension and has put the window into the right save set. (x_embed_frame): New function. * src/xterm.h (FRAME_X_EMBEDDED_P): Fix coding style.

* Fix overflows in HAVE_XSYNC timestamp handlingPaul Eggert2022-08-251-5/+5
| | | | | | | | | | | | | | | | | | | | | | | Also, port to platforms lacking CLOCK_MONOTONIC and int64_t, and use 0 more consistently to represent missing timestamps. * src/xterm.h (struct x_display_info): Omit server_time_monotonic_p and server_time_offset if !HAVE_CLOCK_GETTIME since they are unused in that case. * src/xterm.h (struct x_display_info, struct x_output): * src/xterm.c (x_sync_get_monotonic_time) (x_sync_current_monotonic_time, x_sync_note_frame_times): Use int_fast64_t instead of int64_t as POSIX doesn't guarantee the latter. Similarly for uint_fast64_t. (x_sync_get_monotonic_time, x_sync_current_monotonic_time) (x_sync_note_frame_times, x_display_set_last_user_time): Check for integer overflow in time arithmetic. (CLOCK_MONOTONIC): Define to CLOCK_REALTIME if absent. (x_sync_current_monotonic_time): Check for clock_gettime failure and fall back on CLOCK_REALTIME if CLOCK_MONOTONIC does not work, which POSIX allows. (x_sync_current_monotonic_time, x_sync_note_frame_times) (x_display_set_last_user_time): Use 0 more consistently to represent missing timestamps.
* Fix various problems with mouse highlight on XI2 buildsPo Lu2022-08-251-0/+6
