ARRAYELTS → countof

2026-05-27T04:57:20Z

C2y will standardize countof as the macro that Emacs uses the name ARRAYELTS for. Switch to the standard name, which is supported by GCC 16+, by Clang 21, and by the Gnulib stdcountof-h module already in use for compilers that do not support countof. Also, use countof in a few places where we missed using ARRAYELTS. * admin/coccinelle/arrayelts.cocci: Suggest countof, not ARRAYELTS. * admin/merge-gnulib (GNULIB_MODULES): Add stdcountof-h, as it is now a direct rather than an indirect dependency. * exec/trace.c, src/lisp.h, src/sfnt.c: Include . (ARRAYELTS): Remove. All uses replaced by countof. * lib-src/ebrowse.c, lib-src/etags.c, lib-src/make-docfile.c: * lib-src/seccomp-filter.c, lwlib/lwlib-Xaw.c: Prefer and countof to doing things by hand.

New function memory_full_up

2026-05-24T02:18:52Z

* src/alloc.c (memory_full_up): New function. Replace all callers of memory_full (SIZE_MAX) with callers to this function. This simplifies callers and should make future changes easier. It also saves a whopping 296 bytes in executable size with gcc 16.1.1 20260515 (Red Hat 16.1.1-2) x86-64.

Always compile w32image.c on MinGW (Bug#80924)

2026-04-30T15:52:22Z

This enables features unrelated to native image APIs, such as 'w32-export-frame' and 'yank-media', which need to call GDI+ functions. * configure.ac (HAVE_W32) [!CYGWIN]: Always include w32image.o in W32_OBJ. * etc/NEWS: Drop 'yank-media' '--without-native-image-api' caveat. * src/emacs.c (main): * src/w32select.c (convert_dibv5_to_png): * src/w32term.c (w32_draw_image_foreground): Replace HAVE_NATIVE_IMAGE_API with WINDOWSNT. * src/w32.c (term_ntproc): Remove redundant HAVE_NATIVE_IMAGE_API guard. * src/w32fns.c (Fw32_export_frame) [!WINDOWSNT]: Return nil on Cygwin.

Protect against GCing of last_mouse_window

2025-01-27T07:05:53Z

* src/window.c (last_mouse_window): New global var. All static instances removed, and all their uses replaced with this global var. This fixes a very unlikely bug where last_mouse_window was GC’ed and a new window created in its place. It also fixes several places that assumed NIL_IS_ZERO without static_asserting it. (init_window_once): Initialize the new var.
