Prefer ptrdiff_t to size_t when either will do

2026-05-24T02:18:53Z

Signed types are a bit safer, as they avoid some comparison confusion and -fsanitize=undefined can check more misuses of them. * src/alloc.c (lisp_malloc, lisp_align_malloc) (allocate_string_data, allocate_vector_from_block, object_bytes): * src/coding.c (from_unicode_buffer): * src/decompress.c (acc_size, accumulate_and_process_md5): * src/emacs.c (load_seccomp, shut_down_emacs): * src/fns.c (sxhash_bignum): * src/ftfont.c (get_adstyle_property): * src/image.c (lookup_image, xpm_init_color_cache) (xpm_cache_color): * src/json.c (json_out_str, struct json_parser) (json_make_object_workspace_for_slow_path) (json_make_object_workspace_for, json_parse_array) (json_parse_object): * src/sysdep.c (get_current_dir_name_or_unreachable) (init_sys_modes, convert_speed): * src/termchar.h (struct tty_display_info): * src/textconv.h (struct textconv_conversion_text): * src/xfns.c (struct x_xim_text_conversion_data) (x_encode_xim_text): * src/xselect.c (struct transfer, c_size_for_format) (x_size_for_format, selection_data_for_offset) (selection_data_size, x_start_selection_transfer) (x_continue_selection_transfer): Prefer ptrdiff_t to size_t when either will do. * src/term.c (Ftty__set_output_buffer_size): Limit output buffer size to PTRDIFF_MAX as well as to SIZE_MAX.

Pacify -Wunused-function re get_conversion_field

2025-12-09T02:32:01Z

* src/textconv.c (get_conversion_field): Define only if HAVE_ANDROID, since it is unused on non-Android.

Fix some C symbol extern visibility

2025-12-08T18:41:50Z

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.
