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.
2026-05-28Fix the MSDOS buildPo Lu
* 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.
2026-05-28Fix the Android build againPo Lu
* exec/trace.c (ARRAYELTS, establish_seccomp_filter): Restore ARRAYELTS, since Gnulib is not available in the exec library.
2026-05-27Use compound literal in lisp_h_make_fixnum_wrapPaul Eggert
* 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'’.
2026-05-27Port MinGW GCC 9.2 image.c fix to non MS-WindowsPaul Eggert
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.
2026-05-27pgtk: Fix -Wint-conversion compilation error.Collin Funk
* src/pgtkgui.h (WINDOW_HANDLE_UINTPTR): New macro to override the default one in src/dispextern.h.
2026-05-27Unbreak MS-Windows build broken by Gnulib syncEli Zaretskii
* 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.
2026-05-26Also copy lib/mini-gmp-gnulib.c from GnulibPaul Eggert
2026-05-26ARRAYELTS → countofPaul Eggert
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 <stdcountof.h>. (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 <stdcountof.h> and countof to doing things by hand.
2026-05-26Update from Gnulib by running admin/merge-gnulibPaul Eggert
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.
2026-05-26Pacify GCC better when building the test modulePaul Eggert
* test/Makefile.in ($(test_module)): Compile mini-gmp-gnulib.c, not mini-gmp.c, so that we get its pragmas to pacify GCC.
2026-05-26Omit useless casts found by GCC 16Paul Eggert
GCC 16’s -Wuseless-cast warning can be useful. Fix the useless casts it identifies, and also fix false positives by using compound literals, which are safer anyway than casts. * src/composite.c (composition_adjust_point) (Ffind_composition_internal): * lwlib/xlwmenu.c (xlwMenuResources, xlwMenuClassRec) (resource_widget_value, XlwMenuDestroy, Select): * src/alloc.c (process_mark_stack): * src/data.c (Faref): * src/emacs-module.c (module_extract_big_integer): * src/fileio.c (Finsert_file_contents): * src/frame.h (FRAME_MESSAGE_BUF_SIZE): * src/gtkutil.c (xg_tool_item_stale_p, update_frame_tool_bar): * src/image.c (pbm_load, png_load_body, jpeg_load_body) (tiff_load, gif_load): * src/pdumper.c (ptrdiff_t_to_dump_off, dump_queue_dequeue) (field_relpos, dump_field_emacs_ptr) (dump_object_start_pseudovector, pdumper_remember_scalar_impl) (pdumper_load, syms_of_pdumper): * src/regex-emacs.c (BUF_PUSH, BUF_PUSH_2, POINTER_TO_OFFSET): * src/xdisp.c (remember_mouse_glyph, pint2str): * src/xterm.c (cvt_string_to_pixel, handle_one_xevent): Omit useless casts. Perhaps they were formerly needed, but they should not be needed now. * src/alloc.c (Fmemory_info): * src/category.c (Fdefine_category, Fmodify_category_entry): * src/data.c (Fash): * src/dispextern.h (GLYPH_CODE_P): * src/emacs.c (load_seccomp): * src/fns.c (Flocale_info, maybe_resize_hash_table): * src/indent.c (check_display_width): * src/json.c (symset_size): * src/lisp.h (XUNTAG, BOOL_VECTOR_LENGTH_MAX, obarray_size) (hash_table_index_size): * src/lread.c (make_obarray, grow_obarray, Fobarray_clear): * src/menu.c (digest_single_submenu, x_popup_menu_1): * src/term.c (init_tty): * src/widget.c (update_wm_hints): * src/xdisp.c (truncate_echo_area): * src/xfns.c (x_set_border_pixel): * src/xfont.c (xfont_match, xfont_open): * src/xmenu.c (set_frame_menubar): * test/src/emacs-module-resources/mod-test.c (emacs_module_init): Use compound literal instead of a cast that is useless in some platforms but not others. * src/dispextern.h, src/haikugui.h, src/w32gui.h: (WINDOW_HANDLE_UINTPTR): New macro. * src/frame.c (gui_report_frame_params): * src/xterm.c (x_try_cr_xlib_drawable): Use it. * src/lisp.h (XUNTAG): And tag with UINTPTR_MAX to pacify gcc warning about a constant out of range. (hash_idx_t): Make it int_least32_t, as it need not be exactly 32 bits. (PRIdHASH_IDX): New macro. * src/pdumper.c (dump_queue_dequeue): Use it. * src/profiler.c (setup_cpu_timer): Make a local EMACS_INT rather than int, to avoid need for casting later. * src/syntax.c (uninitialized_interval): Use 1u rather than 1 so the cast is always useful. A compound literal wouldn’t do here, as this macro needs to be an integer constant expression. * src/xfns.c (XICCallback, XICProc): Remove macros. (Xxic_preedit_start_callback): Use a cleaner way to specify it, avoiding the need for type macros, and for a cast if HAVE_XICCALLBACK_CALLBACK. * src/xterm.c (handle_one_xevent): 2nd arg is now XEvent * on all platforms, as there is no need to diverge, and diverging meant we needed lots of unnecessary casts.
2026-05-26Pixel-direct alignment in visual-wrap-prefix-mode (bug#81039)Andrea Alberti
`visual-wrap--content-prefix' previously returned a column count computed as (max (string-width prefix) (ceiling (string-pixel-width prefix) avg-space-width)) with two problems: * `string-width' ignores `buffer-invisibility-spec', so an invisible prefix (hidden ATX markers under `markdown-ts-hide-markup', for example) still reserved its character count on line 1 via a `min-width' display property, shifting the visible heading right. * With variable-pitch fonts, rounding the prefix width up to whole columns added visible padding whenever the natural width did not fall on an exact column boundary. Return the prefix's natural pixel width via `string-pixel-width' instead, which accounts for any display transformation applied to the prefix (invisibility, `display' replacements, text scaling, proportional fonts). Drop the `min-width' property from `visual-wrap--apply-to-line' so line 1 renders at its natural width. Switch the continuation `wrap-prefix' to a mixed-unit `:align-to' sum form: (space :align-to (+ (PIX) (EXTRA-INDENT . width))) where PIX is the prefix's pixel width and EXTRA-INDENT is `visual-wrap-extra-indent' in canonical character widths. The display engine resolves each term per the active frame and sums them, so no Lisp-level unit conversion is needed. Since `min-width' is no longer installed, the accumulation cycle that commit 81a5beb8af0 (bug#73882) worked around cannot recur. Drop the `min-width' strip from `visual-wrap--content-prefix' and the `min-width' removal from `visual-wrap--remove-properties'. Keep `min-width' in `visual-wrap--safe-display-specs' so that lines where other modes install it are not skipped. * lisp/visual-wrap.el (visual-wrap--content-prefix): Return pixel width instead of column count; drop the `min-width' strip. (visual-wrap--apply-to-line): Drop `min-width' on line 1; use mixed-unit `:align-to' sum form for the continuation wrap-prefix. (visual-wrap--adjust-prefix): Handle only string prefixes; the numeric (pixel) case is now handled inline in `--apply-to-line' via the mixed-unit `:align-to' sum form. (visual-wrap--remove-properties): Drop `min-width' removal. (visual-wrap--safe-display-specs): Add note about `min-width'. * test/lisp/visual-wrap-tests.el: Update expected `wrap-prefix' values to the new sum form. (visual-wrap-tests/invisible-prefix): New test motivated by bug#81039. (visual-wrap-tests/negative-extra-indent): New test; verify that a large negative `visual-wrap-extra-indent' produces a valid wrap-prefix (the display engine clamps the stretch to zero). * test/manual/visual-wrap-test.el: New file. Manual test suite for visual-eyeball verification of prefix alignment behavior. Reported-by: Andrea Alberti <a.alberti82@gmail.com> Co-authored-by: Stefan Monnier <monnier@iro.umontreal.ca>
2026-05-26Gnus: Prefer passing functions to message-add-actionStefan Monnier
Building code with code is tricky. E.g. the code in gnus-draft-setup suffered from a security issue because it forgot to quote some arguments (see commit 142b1e0d4c3). * lisp/gnus/gnus-salt.el (gnus-pick-setup-message): * lisp/gnus/gnus-msg.el (gnus-inews-add-send-actions): * lisp/gnus/gnus-draft.el (gnus-draft-setup): Prefer passing functions to message-add-action over passing it ELisp expressions. * lisp/gnus/message.el (message-do-actions): Drop errors but not silently.

This reverts commit 3461b450c5eae3ed53192aa9514e0b1ac1b1c8f2. Gnulib and intprops.h are not available from within the exec helper.
2026-05-24Avoid crash in self-insert-command with non-ASCII auto-fillPip Cet
* src/cmds.c (internal_self_insert): If the autofill function changed the newline character we inserted, don't attempt to restore point. * test/src/cmds-tests.el (self-insert-nonascii-autofill): New.
2026-05-24Avoid crash in self-insert-command for peculiar argumentsPip Cet
* src/cmds.c (internal_self_insert): Don't call auto-fill-function after inserting zero newlines. * test/src/cmds-tests.el (self-insert-zero-newlines): New.

2026-05-24Fix off-by-one error in 'styled_format'Pip Cet
This would (rarely) result in composition properties being shared across the concatenation of two copies of a string. * src/editfns.c (styled_format): Include the first argument in the range. * test/src/editfns-tests.el (editfns-tests--format-composition-property): New.
2026-05-23Fold calls to fix_position into treesit_check_position (bug#80830)Yuan Fu
* src/treesit.c (treesit_check_position): Return the validated value. (Ftreesit_node_first_child_for_pos): (Ftreesit_node_descendant_for_range): (Ftreesit_query_capture): (Ftreesit__linecol_at): Fold calls to fix_position into treesit_check_position in treesit.c.
2026-05-23EVENT_INIT via a compound literalPaul Eggert
This pacifies GCC 16.1.1 x86-64 -Warray-bounds when compiling with -fsanitize=address. It’s also cleaner on more-typical platforms. * src/termhooks.h (EVENT_INIT): Define via a compound literal rather than via a memset plus an assignment. This evaluates the argument lvalue only once, and is more likely to catch type errors.
2026-05-23sfnt.c eassert vs assertPaul Eggert
Use eassert uniformly, instead of assert. * src/sfnt.c [!TEST]: Do not include <assert.h> or use assert. (eassert) [TEST]: New macro.
2026-05-23Better size overflow checking for sfnt.cPaul Eggert
* src/sfnt.c (memory_full_up) [TEST]: New static function. (xmalloc, xcalloc, xrealloc): Use it instead of aborting. (eassert) [TEST]: Remove; no longer needed. (xaddmalloc, xaddrealloc): New static convenience functions. (sfnt_read_cmap_format_12, sfnt_read_loca_table_short) (sfnt_read_loca_table_long, sfnt_read_glyf_table) (sfnt_read_simple_glyph, sfnt_read_compound_glyph) (sfnt_read_glyph, sfnt_build_append, sfnt_build_outline_edges) (sfnt_raster_glyph_outline, sfnt_build_outline_fedges) (sfnt_raster_glyph_outline_exact, sfnt_read_hmtx_table) (sfnt_read_name_table, sfnt_read_meta_table) (sfnt_read_ttc_header, sfnt_read_fpgm_table) (sfnt_read_prep_table, sfnt_create_uvs_context) (sfnt_read_gvar_table, sfnt_read_packed_deltas) (sfnt_vary_simple_glyph, sfnt_vary_compound_glyph): Use the new functions to test for size overflow more reliably. Use a cleaner way to decide whether a pointer addresses the heap not the stack and thus needs freeing. Fix a few more unlikely overflows. (sfnt_read_cmap_format_12): The recently-added eassert is no longer needed, so remove it. (sfnt_read_simple_glyph): Initialize glyph->simple early to simplify later code, as is done in similar functions. Complicate size test to avoid potential unsigned overflow.
2026-05-23Simplify sfnt.c by using long longPaul Eggert
Even the earliest Android had plain ‘long long’, so use that instead of doing it by hand. * src/sfnt.c (struct sfnt_large_integer, sfnt_multiply_divide_1) (sfnt_multiply_divide_2, sfnt_large_integer_add) (sfnt_multiply_divide_round) [!INT64_MAX]: Remove. (sfnt_multiply_divide, sfnt_multiply_divide_rounded) (sfnt_mul_fixed, sfnt_mul_fixed_round, sfnt_div_fixed) (sfnt_div_f26dot6, sfnt_mul_f26dot6, sfnt_mul_f26dot6_round) (sfnt_mul_f2dot14, sfnt_dot_fix_14): Simplify by using long long.
2026-05-23Prefer ptrdiff_t to size_t when either will doPaul Eggert
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.

2026-05-23Be more careful about X selection sizesPaul Eggert
* src/xselect.c (selection_data_for_offset): Offset is size_t, not long, since that’s what caller passes. (selection_data_size): Truncate large selection sizes to a value that is more likely to work without involving undefined behavior. Do not exceed X_ULONG_MAX which is all X can handle, or PTRDIFF_MAX which can confuse underlying code. (x_start_selection_transfer): Invoke selection_data_size just once.

* lwlib/lwlib.c (allocate_widget_instance): Simplify via xzalloc.
2026-05-23Don’t silently truncate file names in exec.cPaul Eggert
* exec/exec.c (format_pid): Simplify. No need for a local array. (exec_0): Shrink local buffer. If names are too long, fail instead of silently truncating them. Be cautious in case symlink is zero length (shouldn’t be possible in Android, but it’s easy to be safe).
2026-05-23Don’t use VLA in etags.c mercury_declPaul Eggert
* lib-src/etags.c (mercury_decl): Don’t use a VLA, as C11+ says VLAs are optional. Instead, redo to omit the need for an array at all.
