* Mark _Noreturn error functions as coldPaul Eggert2019-04-181-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On my platform this made ‘make compile-always’ 1.3% faster. Suggested by Alex Gramiak in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00684.html * configure.ac (nw): Don’t use -Wsuggest-attribute=cold. * lib-src/make-docfile.c (write_globals): Mark noreturn functions as cold. * src/callproc.c (exec_failed): * src/data.c (wrong_length_argument, wrong_type_argument): * src/emacs-module.c (module_abort): * src/emacs.c (terminate_due_to_signal): * src/eval.c (unwind_to_catch): * src/image.c (my_png_error, my_error_exit): * src/json.c (json_out_of_memory, json_parse_error): * src/keyboard.c (quit_throw_to_read_char, user_error): * src/lisp.h (die, wrong_type_argument, wrong_choice) (args_out_of_range, args_out_of_range_3, circular_list) (buffer_overflow, memory_full, buffer_memory_full) (string_overflow, xsignal, xsignal0, xsignal1, xsignal2) (xsignal3, signal_error, overflow_error, error, verror) (nsberror, report_file_errno, report_file_error) (report_file_notify_error, terminate_due_to_signal) (emacs_abort, fatal): * src/lread.c (load_error_old_style_backquotes) (end_of_file_error, invalid_syntax): * src/pdumper.c (error_unsupported_dump_object): * src/puresize.h (pure_write_error): * src/search.c (matcher_overflow): * src/sound.c (sound_perror, alsa_sound_perror): * src/sysdep.c (handle_arith_signal): * src/systime.h (time_overflow): * src/term.c (maybe_fatal, vfatal): * src/textprop.c (text_read_only): * src/timefns.c (invalid_time_zone_specification) (time_error, invalid_hz): * src/xterm.c (x_connection_closed): Use AVOID instead of _Noreturn void, so that it’s marked cold. * src/conf_post.h (__has_attribute_cold) [!__has_attribute]: New macro.

* Revert "Revert "Rely on conservative stack scanning to find "emacs_value"s""Eli Zaretskii2019-03-211-175/+198
| | | | | | | | This reverts commit ee7ad83f20903208404a84b58b7a478b62924570. There was no consensus on reverting 3eb93c07f7a60ac9ce8a16f10c3afd5a3a31243a, so doing that will have to wait until the discussion ends.
* Revert "Rely on conservative stack scanning to find "emacs_value"s"Philipp Stephani2019-03-211-198/+175
| | | | | | | | This reverts commit 3eb93c07f7a60ac9ce8a16f10c3afd5a3a31243a. There was no consensus for that commit, see https://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00150.html. Also, reverting this commit should fix Bug#31238.
* Simplify list creation in C codePaul Eggert2019-03-041-11/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main new thing here is that C code can now say ‘list (a, b, c, d, e, f)’ instead of ‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’, thus relieving callers of the responsibility of counting arguments (plus, the code feels more like Lisp). The old list1 ... list5 functions remain, as they’re probably a bit faster for small lists. * src/alloc.c (cons_listn, pure_listn): New functions. (listn): Omit enum argument. All callers changed to use either new ‘list’ or ‘pure_list’ macros. * src/charset.c (Fdefine_charset_internal): * src/coding.c (detect_coding_system) (Fset_terminal_coding_system_internal): * src/frame.c (frame_size_history_add, adjust_frame_size): * src/gtkutil.c (xg_frame_set_char_size): * src/keyboard.c (command_loop_1): * src/nsfns.m (frame_geometry): * src/widget.c (set_frame_size): * src/xfaces.c (Fcolor_distance): * src/xfns.c (frame_geometry): * src/xterm.c (x_set_window_size_1): * src/xwidget.c (Fxwidget_size_request): Prefer list1i, list2i, etc. to open-coding them. * src/charset.c (Fset_charset_priority): * src/nsterm.m (append2): * src/window.c (window_list): * src/xfaces.c (Fx_list_fonts): Use nconc2 instead of open-coding it. * src/eval.c (eval_sub, backtrace_frame_apply): * src/kqueue.c (kqueue_generate_event): * src/nsterm.m (performDragOperation:): * src/pdumper.c (Fpdumper_stats): * src/w32.c (init_environment): Prefer list1, list2, etc. to open-coding them. * src/font.c (font_list_entities): Parenthesize to avoid expanding new ‘list’ macro. * src/gtkutil.c (GETSETUP): Rename from MAKE_FLOAT_PAGE_SETUP to get lines to fit. Move outside the ‘list’ call, since it’s now a macro. * src/keymap.c (Fmake_keymap): Simplify. * src/lisp.h (list, pure_list): New macros. (list1i): New function.
* Ignore pending_signals when checking for quits.Philipp Stephani2019-02-241-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pending_signals is often set if no quit is pending. This results in bugs in module code if the module returns but no quit is actually pending. As a better alternative, add a new process_input environment function for Emacs 27. That function processes signals (like maybe_quit). * configure.ac: Add module snippet for Emacs 27. * src/module-env-27.h: New file. * src/emacs-module.h.in: Add process_input function to environment interface. * src/emacs-module.c (module_should_quit): Use QUITP macro to check whether the caller should quit. (module_process_input): New function. (initialize_environment): Use it. * src/eval.c: Remove obsolete comment. * test/data/emacs-module/mod-test.c (signal_wrong_type_argument) (signal_errno): New helper functions. (Fmod_test_sleep_until): New test module function. * test/src/emacs-module-tests.el (mod-test-sleep-until): New unit test. * doc/lispref/internals.texi (Module Misc): Document process_input.

| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November.

Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down).

* Module assertions: check for garbage collectionsPhilipp Stephani2017-07-081-2/+4
| | | | | | | | | | | | | | | | | | | | It's technically possible to write a user pointer finalizer that calls into Emacs module functions. This would be disastrous because it would allow arbitrary Lisp code to run during garbage collection. Therefore extend the module assertions to check for this case. * src/emacs-module.c (module_assert_thread): Also check whether a garbage collection is in progress. * test/data/emacs-module/mod-test.c (invalid_finalizer) (Fmod_test_invalid_finalizer): New test module functions. (emacs_module_init): Register new test function. * test/src/emacs-module-tests.el (module--test-assertion) (module--with-temp-directory): New helper macros. (module--test-assertions--load-non-live-object): Rename existing unit test, use helper macros. (module--test-assertions--call-emacs-from-gc): New unit test.
* Remove FIXME comments about sentinel valuesPhilipp Stephani2017-07-021-4/+0
| | | | | | | | | | | These FIXMEs can't be addressed because they would require breaking changes to the module API. Furthermore, other module functions don't return sentinel values as well, so users generally have to call non_local_exit_check anyway. * src/emacs-module.c (module_set_user_ptr) (module_set_user_finalizer, module_vec_set, module_vec_size): Remove FIXME comments.

* Port cleanup check to Oracle Studio 12.5Paul Eggert2017-06-141-0/+4
| | | | | | * src/conf_post.h (__has_attribute_cleanup): Resurrect. * src/emacs-module.c: Verify __has_attribute (cleanup), but in an #if this time.
* Port cleanup attribute to Oracle Studio 12.5Paul Eggert2017-06-131-3/+2
| | | | | | | | | | | * INSTALL (--with-modules): List cleanup attribute as prereq. * src/conf_post.h (__has_attribute_cleanup): Remove; no longer needed. * src/emacs-module.c (MODULE_SETJMP_1): Don’t attempt to verify (__has_attribute (cleanup)), as Oracle Studio 12.5 supports __has_attribute only inside preprocessor expressions. The C compiler should check the cleanup attribute in the next line anyway. (module_reset_handlerlist): Remove an unnecessary ‘const’ that causes Oracle Studio 12.5 to refuse to compile.
* _Noreturn not noreturnPaul Eggert2017-06-121-10/+14
| | | | | | | _Noreturn is more portable to non-C11 platforms. See: https://www.gnu.org/software/gnulib/manual/html_node/stdnoreturn_002eh.html * src/emacs-module.c: Use _Noreturn, not noreturn. No need to include <stdnoreturn.h>. Reindent to fit in 80 columns.
* Avoid compilation warnings with pre-C99 libcEli Zaretskii2017-06-121-4/+5
| | | | | | * src/emacs-module.c (module_free_global_ref) (module_assert_runtime, module_assert_env, value_to_lisp): Use 'pD' instead of C99 't' format descriptor.
