2016-06-08Replace IF_LINT by NONVOLATILE and UNINITPaul Eggert
Inspired by a suggestion from RMS in: http://bugs.gnu.org/23640#58 * .dir-locals.el (c-mode): Adjust to macro changes. * src/conf_post.h (NONVOLATILE, UNINIT): New macros (Bug#23640). (IF_LINT): Remove. All uses replaced by the new macros.
2016-06-01Merge branch 'master' of git.sv.gnu.org:/srv/git/emacsK. Handa
2016-06-01Fix incomplete handling of translation table in a coding system.K. Handa
* coding.c (get_translation): New arg NCHARS. Even if TRANS is an alist, return a character or a vector of character. (produce_chars): Adjust for the above change. (consume_chars): Likewise.
2016-05-30Omit IF_LINT code that no longer seems neededPaul Eggert
Nowadays GCC is smarter, or the Emacs code has mutated, or both, and now is as good a time as any to remove uses of IF_LINT that now seem to be unnecessary. * lib-src/emacsclient.c (set_local_socket): * lib-src/movemail.c (main) [MAIL_USE_MAILLOCK && HAVE_TOUCHLOCK]: * src/buffer.c (fix_start_end_in_overlays, fix_overlays_before): * src/casefiddle.c (casify_region): * src/charset.c (load_charset_map): * src/coding.c (decode_coding_object, encode_coding_object): * src/data.c (Fmake_variable_buffer_local, Fmake_local_variable) (cons_to_unsigned, cons_to_signed): * src/frame.c (make_frame, x_set_frame_parameters): * src/keyboard.c (read_event_from_main_queue): * src/regex.c (regex_compile): * src/syntax.c (back_comment): * src/window.c (Frecenter): * src/xfaces.c (Fx_list_fonts): Remove IF_LINT that no longer seems necessary. * src/image.c (png_load_body, jpeg_load_body): Simplify use of IF_LINT. * src/keyboard.c (read_char): Use IF_LINT (volatile) rather than a pragma dance to pacify GCC -Wclobbered. * src/xdisp.c (x_produce_glyphs): Rewrite to avoid need for IF_LINT. * src/xterm.c (x_connection_closed): Now _Noreturn, which should mean we do not need IF_LINT any more. (x_io_error_quitter): Now _Noreturn. Put an 'assume (false)’ at the end, to forestall warnings from older compilers.
2016-05-24Update allowable arguments for open-network-streamKen Brown
* src/coding.c (Ffind_operation_coding_system): Allow t as a target for open-network-stream. (Bug #23540)
2016-04-04; Fix typo in previous patch.Paul Eggert
2016-04-04New C macro AUTO_STRING_WITH_LENPaul Eggert
Put a bit less pressure on the garbage collector by defining a macro that is like AUTO_STRING but also allows null bytes in strings, and by extending AUTO_STRING to work with any unibyte string. * src/alloc.c (verify_ascii): Remove; all uses removed. AUTO_STRING can now be used on non-ASCII unibyte strings. * src/lisp.h (AUTO_STRING): Now allows non-ASCII unibyte strings. (AUTO_STRING_WITH_LEN): New macro. * src/coding.c (from_unicode_buffer): * src/editfns.c (format_time_string): * src/emacs-module.c (module_make_string, module_format_fun_env): * src/fileio.c (Fexpand_file_name): * src/font.c (font_parse_family_registry): * src/ftfont.c (ftfont_get_charset): * src/keymap.c (silly_event_symbol_error): * src/menu.c (single_menu_item): * src/sysdep.c (system_process_attributes): Use AUTO_STRING_WITH_LEN if possible. * src/emacs-module.c (module_make_function): * src/fileio.c (report_file_errno, report_file_notify_error): * src/fns.c (Flocale_info): * src/sysdep.c (system_process_attributes): Use AUTO_STRING if possible. This is doable more often now that AUTO_STRING works on any unibyte string.

2016-03-10Rework C source files to avoid ^(Paul Eggert
Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.

2015-09-16Omit unnecessary \ before paren in C docstringsPaul Eggert
Although \( is needed in docstrings in Elisp code, it is not needed in docstrings in C code, since C function definitiions do not start with a parenthesis. The backslashes made the docstrings a bit harder to read and to format in columns. Also, some C docstrings had ( in column 1 and this did not appear to be causing any problems. So, simplify C docstrings by replacing \( with ( and \) with ).
2015-09-16Add -Wswitch to --enable-gcc-warningsPaul Eggert
Make --enable-gcc-warnings a bit pickier, by also using -Wswitch. * configure.ac (WERROR_CFLAGS): Don’t add -Wno-switch. * lib-src/etags.c (main, consider_token, C_entries): * src/coding.c (encode_invocation_designation): * src/data.c (Ftype_of): * src/eval.c (Fdefvaralias, default_toplevel_binding) (Fbacktrace__locals, mark_specpdl): * src/lisp.h (record_xmalloc): * src/syntax.c (scan_lists, scan_sexps_forward): * src/window.c (window_relative_x_coord): * src/xdisp.c (push_it, pop_it): * src/xterm.c (xg_scroll_callback, x_check_fullscreen): Error out or do nothing (as appropriate) if a switch statement with an enum value does not cover all of the enum. * src/dispextern.h (struct iterator_stack_entry.u.comp): Remove unused member discovered by using -Wswitch. * src/lisp.h (record_xmalloc): Add a ‘+ 0’ to pacify -Wswitch. * src/vm-limit.c (check_memory_limits): Simplify warning-diagnostic computation by using a table.
2015-08-26Assume GC_MARK_STACK == GC_MAKE_GCPROS_NOOPSPaul Eggert
This removes the need for GCPRO1 etc. Suggested by Stefan Monnier in: http://lists.gnu.org/archive/html/emacs-devel/2015-08/msg00918.html * doc/lispref/internals.texi (Writing Emacs Primitives): * etc/NEWS: Document the change. * src/alloc.c (gcprolist, dump_zombies, MAX_ZOMBIES, zombies) (nzombies, ngcs, avg_zombies, max_live, max_zombies, avg_live) (Fgc_status, check_gcpros, relocatable_string_data_p, gc-precise): * src/bytecode.c (mark_byte_stack) [BYTE_MARK_STACK]: * src/eval.c (gcpro_level) [DEBUG_GCPRO]: * src/lisp.h (struct handler.gcpro, struct gcpro, GC_MARK_STACK) (GC_USE_GCPROS_AS_BEFORE, GC_MAKE_GCPROS_NOOPS) (GC_MARK_STACK_CHECK_GCPROS, GC_USE_GCPROS_CHECK_ZOMBIES) (BYTE_MARK_STACK, GCPRO1, GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6) (GCPRO7, UNGCPRO, RETURN_UNGCPRO): Remove. All uses removed. The code now assumes GC_MARK_STACK == GC_MAKE_GCPROS_NOOPS. * src/bytecode.c (relocate_byte_stack): Rename from unmark_byte_stack, since it now only relocates. All callers changed. * src/frame.c (make_frame): Add an IF_LINT to pacify GCC 5.2 with GCPROs removed. * src/systime.h: Use EMACS_LISP_H as the canary instead of GCPRO1. * test/automated/finalizer-tests.el (finalizer-basic) (finalizer-circular-reference, finalizer-cross-reference) (finalizer-error): * test/automated/generator-tests.el (cps-test-iter-close-finalizer): Remove tests, as they depend on gc-precise.
2015-07-27Fix uninitalized value in encode_coding_objectPaul Eggert
* src/coding.c (encode_coding_object): Also initialize coding->src_pos and coding->src_pos_byte when NILP (src_object). This avoids later use of uninitialized storage.

2015-05-31Treat batch stdout/stderr like standard displayPaul Eggert
Calls like (print FOO) could generate improperly encoded or hard-to-read output if FOO contains characters outside the system locale. Fix this by treating batch stdout and stderr like interactive standard display, when it comes to transliterating and encoding characters (Bug#20545). * doc/emacs/mule.texi (Communication Coding): * doc/lispref/display.texi (Active Display Table): * doc/lispref/nonascii.texi (Locales): * etc/NEWS: * src/coding.c (syms_of_coding): * src/dispnew.c (syms_of_display): Document this. * src/print.c: Include disptab.h. (printchar_to_stream): New function, with much of the guts of the old Fexternal_debugging_output, except this one also uses the standard display table. (printchar, strout, Fexternal_debugging_output): Use it.
2015-05-31Remove unused DEFSYMsPaul Eggert
Remove DEFSYMs that aren't used at the C level.

All uses changed. Define only if not already defined, so that one can debug with -DNIL_IS_NONZERO. * xdisp.c (init_iterator): Remove unnecessary initializations to 0.
2015-01-19Prefer memset to repeatedly assigning QnilPaul Eggert
* alloc.c (allocate_pseudovector): Catch more bogus values. * alloc.c (allocate_pseudovector): * callint.c (Fcall_interactively): * coding.c (syms_of_coding): * fringe.c (init_fringe): Verify that Qnil == 0. * callint.c (Fcall_interactively): * eval.c (Fapply, Ffuncall): * fns.c (mapcar1, larger_vector): * font.c (font_expand_wildcards): * fringe.c (init_fringe): Prefer memset to assigning zeros by hand. * callint.c (Fcall_interactively): Remove duplicate assignment of Qnil to args[i]. * coding.c (syms_of_coding): Prefer LISP_INITIALLY_ZERO to assigning zeros by hand. * fileio.c (Ffile_selinux_context): Rewrite to avoid need for Lisp_Object array. * lisp.h (XLI_BUILTIN_LISPSYM): New macro.

2015-01-11* coding.c (Fcoding_system_plist): Use common style for docstring.Dmitry Antipov
2015-01-05Compute C decls for DEFSYMs automaticallyPaul Eggert
Fixes Bug#15880. This patch also makes Q constants (e.g., Qnil) constant addresses from the C point of view. * make-docfile.c: Revamp to generate table of symbols, too. Include <stdbool.h>. (xstrdup): New function. (main): Don't process the same file twice. (SYMBOL): New constant in enum global_type. (struct symbol): Turn 'value' member into a union, either v.value for int or v.svalue for string. All uses changed. (add_global): New arg svalue, which overrides value, so that globals can have a string value. (close_emacs_global): New arg num_symbols; all uses changed. Output lispsym decl. (write_globals): Output symbol globals too. Output more ATTRIBUTE_CONST, now that Qnil etc. are C constants. Output defsym_name table. (scan_c_file): Move most of guts into ... (scan_c_stream): ... new function. Scan for DEFSYMs and record symbols found. Don't read past EOF if file doesn't end in newline. * alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle: * casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.c: * composite.c, data.c, dbusbind.c, decompress.c, dired.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, fns.c, font.c, fontset.c: * frame.c, fringe.c, ftfont.c, ftxfont.c, gfilenotify.c, gnutls.c: * image.c, inotify.c, insdel.c, keyboard.c, keymap.c, lread.c: * macfont.m, macros.c, minibuf.c, nsfns.m, nsfont.m, nsimage.m: * nsmenu.m, nsselect.m, nsterm.m, print.c, process.c, profiler.c: * search.c, sound.c, syntax.c, term.c, terminal.c, textprop.c, undo.c: * window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.c: * xselect.c, xsettings.c, xterm.c: Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs). These names are now defined automatically by make-docfile. * alloc.c (init_symbol): New function. (Fmake_symbol): Use it. (c_symbol_p): New function. (valid_lisp_object_p, purecopy): Use it. * alloc.c (marked_pinned_symbols): Use make_lisp_symbol instead of make_lisp_ptr. (garbage_collect_1): Mark lispsym symbols. (CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro. (mark_object): Use it. (sweep_symbols): Sweep lispsym symbols. (symbol_uses_obj): New function. (which_symbols): Use it. Work for lispsym symbols, too. (init_alloc_once): Initialize Vpurify_flag here; no need to wait, since Qt's address is already known now. (syms_of_alloc): Add lispsym count to symbols_consed. * buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0), when testing whether storage is all bits zero. * dispextern (struct image_type): * font.c (font_property_table): * frame.c (struct frame_parm_table, frame_parms): * keyboard.c (scroll_bar_parts, struct event_head): * xdisp.c (struct props): Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and Lisp_Object *, since Qfoo is no longer an object whose address can be taken. All uses changed. * eval.c (run_hook): New function. Most uses of Frun_hooks changed to use it, so that they no longer need to take the address of a Lisp sym. (syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable. * frame.c (syms_of_frame): Add defsyms for the frame_parms table. * keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here. DEFSYM Qdeactivate_mark before the corresponding var. * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line instead of interning their symbols; this avoids duplicates. (LISP_INITIALLY, TAG_PTR) (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT): New macros. (LISP_INITIALLY_ZERO): Use it. (enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol) (EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*): Move decls up, to avoid forward uses. Include globals.h earlier, too. (make_lisp_symbol): New function. (XSETSYMBOL): Use it. (DEFSYM): Now just a placeholder for make-docfile. * lread.c (DEFINE_SYMBOLS): Define, for globals.h. (intern_sym): New function, with body taken from old intern_driver. (intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t. All uses changed. (define_symbol): New function. (init_obarray): Define the C symbols taken from lispsym. Use plain DEFSYM for Qt and Qnil. * syntax.c (init_syntax_once): No need to worry about Qchar_table_extra_slots.

2014-09-07Fix bug uncovered by changing alloca to auto buffer.Paul Eggert
* coding.c (growable_destination): New function. (produce_chars): Use it for sanity checks. Do not fiddle with dst_end if the source and destination are both nil, as it's the caller's responsibility to avoid overlap. * keyboard.c (read_decoded_event_from_main_queue): The destination must be MAX_MULTIBYTE_LENGTH times the max source length, not 4 times, to prevent decode_coding_c_string from trying to reallocate a destination. This removes the need for the FIXME. Fixes: debbugs:18410
2014-09-07Use SAFE_ALLOCA etc. to avoid unbounded stack allocation.Paul Eggert
This follows up on the recent thread in emacs-devel on alloca; see: http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00042.html This patch also cleans up alloca-related glitches noted while examining the code looking for unbounded alloca. * alloc.c (listn): * callproc.c (init_callproc): Rewrite to avoid need for alloca. * buffer.c (mouse_face_overlay_overlaps) (report_overlay_modification): * buffer.h (GET_OVERLAYS_AT): * coding.c (make_subsidiaries): * doc.c (Fsnarf_documentation): * editfns.c (Fuser_full_name): * fileio.c (Ffile_name_directory, Fexpand_file_name) (search_embedded_absfilename, Fsubstitute_in_file_name): * fns.c (Fmake_hash_table): * font.c (font_vconcat_entity_vectors, font_update_drivers): * fontset.c (fontset_pattern_regexp, Ffontset_info): * frame.c (Fmake_terminal_frame, x_set_frame_parameters) (xrdb_get_resource, x_get_resource_string): * ftfont.c (ftfont_get_charset, ftfont_check_otf, ftfont_drive_otf): * ftxfont.c (ftxfont_draw): * image.c (xbm_load, xpm_load, jpeg_load_body): * keyboard.c (echo_add_key, menu_bar_items, tool_bar_items): * keymap.c (Fdescribe_buffer_bindings, describe_map): * lread.c (openp): * menu.c (digest_single_submenu, find_and_call_menu_selection) (find_and_return_menu_selection): * print.c (PRINTFINISH): * process.c (Fformat_network_address): * scroll.c (do_scrolling, do_direct_scrolling, scrolling_1): * search.c (search_buffer, Fmatch_data, Fregexp_quote): * sound.c (wav_play, au_play): * syntax.c (skip_chars): * term.c (tty_menu_activate, tty_menu_show): * textprop.c (get_char_property_and_overlay): * window.c (Fset_window_configuration): * xdisp.c (safe__call, next_overlay_change, vmessage) (compute_overhangs_and_x, draw_glyphs, note_mouse_highlight): * xfaces.c (face_at_buffer_position): * xmenu.c (x_menu_show): Use SAFE_ALLOCA etc. instead of plain alloca, since the allocation size isn't bounded. * callint.c (Fcall_interactively): Redo memory_full check so that it can be done at compile-time on some platforms. * coding.c (MAX_LOOKUP_MAX): New constant. (get_translation_table): Use it. * callproc.c (call_process): Use SAFE_NALLOCA instead of SAFE_ALLOCA, to catch integer overflows on size calculation. (exec_failed) [!DOS_NT]: New function. (child_setup) [!DOS_NT]: Use it. * editfns.c (Ftranspose_regions): Hoist USE_SAFE_ALLOC + SAFE_FREE out of 'if'. * editfns.c (check_translation): Allocate larger buffers on the heap. * eval.c (internal_lisp_condition_case): Check for MAX_ALLOCA overflow. * fns.c (sort_vector): Use SAFE_ALLOCA_LISP rather than Fmake_vector.

(SAFE_ALLOCA_STRING): ... new macro with different API. This fixes a portability problem, namely, alloca result passed to another function. All uses changed. (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Check for MAX_ALLOCA, not MAX_ALLOCA - 1. * regex.c (REGEX_USE_SAFE_ALLOCA, REGEX_SAFE_FREE) (REGEX_ALLOCATE): New macros. (REGEX_REALLOCATE, REGEX_ALLOCATE_STACK, REGEX_REALLOCATE_STACK) (REGEX_FREE_STACK, FREE_VARIABLES, re_match_2_internal): Use them. * xdisp.c (message3): Use SAFE_ALLOCA_STRING rather than doing it by hand. (decode_mode_spec_coding): Store directly into buf rather than into an alloca temporary and copying the temporary to the buf. Fixes: debbugs:18410
