dbus-call-method-asynchronously supports also an ERROR-HANDLER

2026-05-28T08:03:05Z

* doc/misc/dbus.texi (Asynchronous Methods): HANDLER can also be (HANDLER . ERROR-HANDLER). * etc/NEWS: Mention ERROR-HANDLER of dbus-call-method-asynchronously. * lisp/net/dbus.el (dbus-call-method-asynchronously): Adapt docstring. (dbus-check-event, dbus-handle-event): HANDLER can also be (HANDLER . ERROR-HANDLER). * src/dbusbind.c (Fdbus_message_internal): HANDLER can also be (HANDLER . ERROR-HANDLER). (Bug#80952) * test/lisp/net/dbus-tests.el (dbus--test-method-another-handler) (dbus--test-method-error-handler): New defvars. (dbus--test-method-another-handler) (dbus--test-method-error-handler): New functions. (dbus-test04-call-method-error-handler): New test. (dbus-test10-keep-fd): Extend test.

Fix the MSDOS build

2026-05-28T04:59:55Z

* msdos/sedlibmk.inp (GL_GNULIB_STDC_[^ =] &c.): Rename from GL_STDC_... and define to 1 before other variables prefixed GL_GNULIB_ are defined to 0. (NEXT_AS_FIRST_DIRECTIVE_STDBIT_H) (NEXT_AS_FIRST_DIRECTIVE_STDCOUNTOF_H, STDCOUNTOF_H): Define. (GL_HAVE_STDBIT_H_CONDITION): Replace GL_GENERATE_STDBIT_H_CONDITION. (CXX_HAVE_STDCOUNTOF_H, GL_GNULIB_STREQ, GL_GNULIB_MEMEQ) (GL_GNULIB_STRNUL, GL_GENERATE_STDCOUNTOF_H_CONDITION): Substitute "1". * src/conf_post.h (_REGEX_AVOID_UCHAR_H) [MSDOS]: Define to 1. * src/term.c (init_tty) [MSDOS]: Set TN_max_colors to 16, which was deleted inadvertently with recent MS Windows modifications. * config.bat: Rename stdcountof.in.h appropriately.

Fix the Android build again

2026-05-28T03:31:16Z

* exec/trace.c (ARRAYELTS, establish_seccomp_filter): Restore ARRAYELTS, since Gnulib is not available in the exec library.

Use compound literal in lisp_h_make_fixnum_wrap

2026-05-27T21:01:40Z

* src/lisp.h (lisp_h_make_fixnum_wrap) [USE_LSB_TAG]: Use compound literal, not cast. This pacifies -Wuseless-cast when building on Fedora 44 x86-64 with ‘./configure --enable-gcc-warnings CFLAGS='-O2 -DDEFINE_KEY_OPS_AS_MACROS'’.

Port MinGW GCC 9.2 image.c fix to non MS-Windows

2026-05-27T15:37:39Z

Avoid useless casts on GCC 14+ platforms on non MS-Windows, by using a cast only if HAVE_NTGUI. That cast should not provoke -Wuseless-cast regardless of how MS-Windows defines HDC, since it casts to an Emacs-defined type. This change lets the code compile again on Fedora 44 with --enable-gcc-warnings. * src/dispextern.h (PIX_CONTAINER_TO_CONTEXT): New macro. It defaults to the identity macro. (Emacs_Pix_Context): Default to Emacs_Pix_Container. * src/image.c (pbm_load, png_load_body, jpeg_load_body) (tiff_load, gif_load, svg_load_image): Use the new macro instead of a cast.

pgtk: Fix -Wint-conversion compilation error.

2026-05-27T14:59:54Z

* src/pgtkgui.h (WINDOW_HANDLE_UINTPTR): New macro to override the default one in src/dispextern.h.

Unbreak MS-Windows build broken by Gnulib sync

2026-05-27T13:30:23Z

* src/conf_post.h: Add leading underscores to 'gl_consolesafe_*' functions, to follow Gnulib's renaming. * src/image.c (pbm_load, png_load_body, jpeg_load_body) (tiff_load): Revert previous change that removed "useless" casts, as removing them triggers warnings from MinGW GCC 9.2.

Also copy lib/mini-gmp-gnulib.c from Gnulib

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.

Update from Gnulib by running admin/merge-gnulib

2026-05-27T04:57:20Z

In addition to the automatic changes, also do the following, needed due to recent Gnulib changes. * admin/merge-gnulib (AVOIDED_MODULES): Add btoc32, c32_apply_type_test, c32_get_type_test, c32isalnum, c32rtomb, c32tolower, c32toupper, localeinfo, mbrtoc32-regular. Remove btowc, iswctype, mbrtowc, wcrtomb, wctype, wctype-h. Also remove iswblank, iswdigit, iswxdigit, locale-h, raise, stdarg-h, some of which perhaps could have been removed earlier. * configure.ac (_REGEX_AVOID_UCHAR_H): New macro.
