* | Allow disabling of reloading files on doc read failureSpencer Baugh2025-09-131-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Reloading a byte-compiled file when we fail to fetch some docstring in it is not guaranteed to work and can cause subtle bugs which are worse than simply not having a docstring. Add 'documentation-dynamic-reload' variable to allow disabling this behavior. See the discussion in https://lists.gnu.org/archive/html/emacs-devel/2025-08/msg00304.html for more details. * src/doc.c (syms_of_doc): Add 'documentation-dynamic-reload'. (Fdocumentation, Fdocumentation_property): Check value of 'documentation-dynamic-reload'.
* | Ignore keymaps at point for positions outside the bufferSpencer Baugh2025-09-091-22/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct a few edge cases where we used the keymaps at point when looking up keymaps for an event position which is outside the current buffer. Namely: - Clicking on a part of the mode line which is after the end of mode-line-format produces an event with non-nil posn-area but nil posn-string. - Even if posn-string doesn't have a local keymap, we should still ignore the keymaps at point if posn-string is non-nil. * src/keymap.c (Fcurrent_active_maps): Ignore keymaps at point for more positions outside the buffer. (bug#76620)

E.g. this can occur while loading `uni-special-lowercase.el` where `hack-local-variables--find-variables` uses `downcase` which triggers loading `uni-special-lowercase.el`, ... * lisp/international/mule-cmds.el (ucs-names): Explicitly require `charprop`. * src/Makefile.in ($(lispsource)/loaddefs.el): Depend on `charprop`.
* | Harmonise doc strings for {re-,posix-,}search-{forward,backward}Mattias Engdegård2025-09-071-61/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The doc strings for re-search-forward and re-search-backward have been improved (bug#25193, bug#31584) but the corresponding posix- and non-regexp search functions still have the original text, despite describing the exact same mechanism. There is no reason for them to differ, so we make them all use the updated version which also is more readable. Any future doc string improvements should be made to all of them in the same way for consistency. * src/search.c (Fsearch_backward, Fsearch_forward) (Fposix_search_backward, Fposix_search_forward): Use text from Fre_search_forward and Fre_search_backward.

* | Attempt to fix assertion violations in bug#79304Eli Zaretskii2025-08-251-21/+8
| | | | | | | | | | | | | | | | | | | | The following changes make the changes for bug#79275 less radical, closer to their previous shape, while still fixing that bug. * src/xdisp.c (push_prefix_prop, get_it_property): Restore original code that determined the object and position on it. (get_line_prefix_it_property): Take FROM_BUFFER from the actual object of the prefix property.
* | Disallow string data resizing (bug#79784)Mattias Engdegård2025-08-244-87/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only allow string mutation that is certain not to require string data to be resized and reallocated: writing bytes into a unibyte string, and changing ASCII to ASCII in a multibyte string. This ensures that mutation will never transform a unibyte string to multibyte, that the size of a string in bytes never changes, and that the byte offsets of characters remain the same. Most importantly, it removes a long-standing obstacle to reform of string representation and allow for future performance improvements. * src/data.c (Faset): Disallow resizing string mutation. * src/fns.c (clear_string_char_byte_cache): * src/alloc.c (resize_string_data): Remove. * test/src/data-tests.el (data-aset-string): New test. * test/lisp/subr-tests.el (subr--subst-char-in-string): Skip error cases. * test/src/alloc-tests.el (aset-nbytes-change): Remove test that is no longer relevant. * doc/lispref/strings.texi (Modifying Strings): * doc/lispref/sequences.texi (Array Functions): * doc/lispref/text.texi (Substitution): Update manual. * etc/NEWS: Announce.
* | Fix line-prefix display when there's a 'display' string at BOLEli Zaretskii2025-08-231-19/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/xdisp.c (push_it): Reset the 'string_from_prefix_prop_p' flag. (try_window_id): Disable this optimization if the last unchanged at-beg row begins with a display or overlay string and there;s a line/wrap-prefix property on the row. (push_prefix_prop): Accept an additional argument FROM_BUFFER to indicate that the prefix property was found on buffer text underlying a display or overlay property, and set up the position to pop to accordingly. Reset the 'string_from_display_prop_p' flag of the iterator after pushing IT to set up for iterating the prefix string. (get_it_property): Use it->string, not it->object, as indication that prefix property is on a string. (get_line_prefix_it_property): Accept an additional argument: pointer to a flag indicating that the prefix property was found on buffer text underlying a display or overlay property. Callers adjusted. (handle_line_prefix): Use the FROM_BUFFER flag to correctly handle prefix properties on buffer text at the same position as a display string. (Bug#79275)
* | Speed up JSON parsing by not maintaining line and column (bug#79192)Mattias Engdegård2025-08-211-88/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use the current parsing position instead. The line and column in the error weren't used (nor very accurate to begin with) and the user can easily compute them when needed. The line number calculation is kept just in case but deprecated, for removal in Emacs 32. * src/json.c (struct json_parser, json_parser_init): Update parser state. (json_signal_error): New position computation. (json_skip_whitespace_internal): Remove. (is_json_whitespace): New. (json_skip_whitespace, json_skip_whitespace_if_possible) (json_parse_unicode, json_parse_string, json_parse_number) (json_parse_value): Simplify and rewrite for efficiency. (count_chars, count_newlines) (string_byte_to_pos, string_byte_to_line) (buffer_byte_to_pos, buffer_byte_to_line): New. (Fjson_parse_string, Fjson_parse_buffer): Adapt to new parser state. * test/src/json-tests.el (json-tests--parse-string-error-pos) (json-tests--parse-buffer-error-pos, json-parse-error-position): New. * etc/NEWS: Note deprecation of line and column.

| | | | | | | | | | | | | | | | | | | | | | | | | | end_of_file_error previously always signaled end-of-file with load-true-file-name if that was non-nil (and a string). However, this might be the wrong thing to do; for example, if a file being loaded calls read on a buffer. * src/lread.c (end_of_file_error): <source>: New argument; check it to determine what data to signal with. (bug#68546) (read_char_escape, read_char_literal, read_string_literal) (skip_space_and_comments, read0): Pass source to end_of_file_error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | .waiting_thread and .thread could be left set to non-NULL values in a deleted fd_callback_info entry. These would never be cleared by e.g. clear_waiting_thread_info since that only clears fd_callback_info entries up to max_desc. Clear fd_callback_info entirely when deleting an entry. * src/process.c (clear_fd_callback_data): Add. (delete_write_fd, delete_keyboard_wait_descriptor): Call clear_fd_callback_data. (bug#79201) (delete_read_fd): Remove duplicated clearing code. (deactivate_process): Remove duplicate recompute_max_desc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the accessibility role of Emacs windows to be "standard window" (AXWindow) instead of "text field" (AXTextField). This matches other applications on NS, as can be verified with any accessibility inspector. All widely used NS ports, such as Emacs Plus, have this patch already applied. As for practical impact, this change makes Emacs, for example, work with tiling window managers, such as Yabai, where many users report problems with Emacs specifically, and are instructed to simply avoid the official NS port of GNU Emacs due to this problem. * src/nsterm.m: ([EmacsWindow accessibilityAttributeValue:]): Make the accessibility role of Emacs windows to be "standard window" (AXWindow) instead of "text field" (AXTextField).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare for the next Gnulib merge by disabling the optional support for non-Gregorian calendars recently added to Gnulib’s nstrftime module. This would be tricky to integrate with Emacs, as Emacs has its own (much fancier) calendar system, one that at least for the Persian calendar sometimes disagrees with Gnulib’s, and it’s likely not worth the trouble of reconciling the conflicts. * src/conf_post.h (SUPPORT_NON_GREG_CALENDARS_IN_STRFTIME): New macro, defined to false. * admin/merge-gnulib (GNULIB_MODULES): nstrftime → nstrftime-limited.
