* NS: Add native image support for HEIF, SVG and WEBP on GNUstepYavor Doganov2026-01-172-5/+31

* Inhibit unused variable warning in NSTRACE_WHEN (bug#80096)Stéphane Marks2026-01-131-1/+1

* Add frame identifiers (bug#80138)Stéphane Marks2026-01-138-0/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A unique frame id is assigned to a new or cloned frame, and reused on an undeleted frame. The id facilitates unambiguous identification among frames that share identical names or titles, deleted frames where a live frame object no longer exists that we can resurrect by id, for example via 'tab-bar-undo-close-tab'. It also aids debugging at the C level using the frame struct member id. Rewrite 'clone-frame' and 'undelete-frame' to not let bind variables that 'make-frame' uses to avoid conflicts with nested 'make-frame' calls, for example via 'after-make-frame-functions'. * lisp/frame.el (clone-frame, undelete-frame): Use 'frame--purify-parameters' to supply parameters explicitly. (undelete-frame--save-deleted-frame): Save frame id for restoration. (undelete-frame): Restore frame id. (frame--purify-parameters): New defun. (make-frame): Assign a new id for a new or cloned frame, reuse for undeleted frame. * src/frame.h (struct frame): Add id member.

(syms_of_frame <Sframe_id>): New defsubr. (syms_of_frame <Qinternal_id>): New DEFSYM. (syms_of_frame <frame_internal_parameters>): Add 'Qinternal_id'. * src/androidfns.c (Fx_create_frame): * src/haikufns.c (Fx_create_frame): * src/nsfns.m (Fx_create_frame): * src/pgtkfns.c (Fx_create_frame): * src/w32fns.c (Fx_create_frame): * src/xfns.c (Fx_create_frame): Call 'frame_set_id_from_params'. * doc/lispref/frames.texi: Add documentation. * etc/NEWS: Announce frame id.

| | | | | | | * configure.ac: Check for 'NSImageNameCaution' declaration when building on GNUstep. * src/nsterm.m ([EmacsBell init]): Use fallback implementation on GNUstep only if 'NSImageNameCaution' is not declared. (Bug#80107)
* Less stingy lisp-eval-depth supply for debuggerMattias Engdegård2026-01-091-6/+7
| | | | | | * src/eval.c (call_debugger, signal_or_quit): Raise extra headroom to 200 levels. The debugger is sometimes entered via handler-bind so we raise the bar there as well (bug#80154).

* Compile queries in treesit-f-l-recompute-features (bug#80108)Yuan Fu2026-01-011-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The direct cause of the problem in the bug report is that when user runs treesit-font-lock-recompute-features to add the emacs-devel feature in c-ts-mode's mode hook, the added query for emacs-devel aren't compiled. This change consists of two parts: 1. The immediate fix: validate and compile queries in treesit-font-lock-recompute-features. 2. To make it more fool-proof, change treesit-font-lock-rules back to compile the queries and make treesit--compile-query-with-cache support compiled queries. This way, as long as the query goes through treesit-font-lock-rules, it'll be compiled eventually and not cause slow-down. I had to add some c-level functions, but they're kind of overdue anyway, so I don't have any problem adding them to the API. * lisp/treesit.el (treesit--compile-query-with-cache): Support compiled queries. (treesit-font-lock-rules): Compile the queries (but not eagerly). (treesit-font-lock-recompute-features): Validate and compile queries. (treesit-major-mode-setup): Remove call to treesit-validate-and-compile-font-lock-rules since it's now called in treesit-font-lock-recompute-features. * src/treesit.c (Ftreesit_query_eagerly_compiled_p): (Ftreesit_query_source): New functions. * doc/lispref/parsing.texi (Pattern Matching): Add manual entries for the new functions.

| | | | | | | | | | | | | | | | | Suggested by Mattias Engdegård (bug#80021#17). * src/lisp.h (lisp_h_FIXNUMP, lisp_h_TAGGEDP): Go back to the simpler (X&7) == TAG approach for checking object tags. This reverses my commit ccdb08ef4ed8f96e79aa06cf5e806c9c487d58ad “Improve performance of CONSP, FIXNUMP, etc.” dated 2018-08-25 13:39:18 -0700, though it keeps the TAGGEDP function the older commit introduced. Although the older commit improved performance on its circa 2010 platform, when I ran today’s ‘make -C lisp compile-always’ benchmark on Ubuntu 25.10 which uses gcc (Ubuntu 15.2.0-4ubuntu4) on an circa-2021 Intel Xeon W-1350, this patch makes the ‘make -C lisp compile-always’ benchmark 3.1% faster. Although the patch unfortunately also makes the Emacs text segment 0.6% larger, in this case speed and simplicity beat text size in importance.
