      Rework C source files to avoid ^( · 7352c6c6
      Paul Eggert authored
      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.

      xwidgets style cleanup · 7c3d742c
      Paul Eggert authored
      Adjust the newly-added Xwidgets code so that it uses a more-typical
      Emacs style.  This should not affect behavior, except that in
      a few places it adds runtime checks that Lisp arguments are of
      the proper type, and in one place it uses more-precise arithmetic.
      * src/buffer.c, src/dispnew.c, src/emacs.c, src/emacsgtkfixed.c:

      New forward or incomplete decls, so that includers need not
      assume the corresponding .h files are already included, or that
      HAVE_XWIDGETS is defined.
      (struct xwidget_type, xwidget_from_id): Remove; unused.

      Omit unnecessary \ before paren in C docstrings · 032ce1c7
      Paul Eggert authored
      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 ).

      * src/print.c (print_error_message): Translate quotes and command
      keys in errmsg so that users see, e.g., "Symbol’s value as
      variable is void: foo" when text-quoting-style is curved.

      Treat batch stdout/stderr like standard display · 467af178
      Paul Eggert authored
      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).

      Compute C decls for DEFSYMs automatically · 58f2d6ef
      Paul Eggert authored
      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:

      * window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.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.

      Port better to AddressSanitizer. · 3517da70
      Paul Eggert authored
      These changes suffice for temacs on x86-64 with GCC 4.9.2 and
      -fsanitize=address.
      * alloc.c (valid_pointer_p) [ADDRESS_SANITIZER]:
      Return -1 or 0, as the pipe trick doesn't work.
      * alloc.c (relocatable_string_data_p, mark_object, sweep_symbols):
      * data.c (Ffset):
      * print.c (print_object):
      When a pointer-check primitive returns -1, do not assume this
      means the pointer is valid or that the underlying system has failed.
      It could just be that addresses are being sanitized so Emacs can't
      test for pointer validity.
      * lisp.h (defined_GC_CHECK_STRING_BYTES): New constant.
      (USE_STACK_STRING) [GC_CHECK_STRING_BYTES]: Now false, since the
      string validity checker doesn't work on stack-based strings.

      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.
      (Fbase64_encode_region, Fbase64_decode_region):
      Avoid unnecessary calls to SAFE_FREE before 'error'.
      * buffer.c (mouse_face_overlay_overlaps):
      * editfns.c (Fget_pos_property, check_translation):
      * eval.c (Ffuncall):
      * font.c (font_unparse_xlfd, font_find_for_lface):
      * ftfont.c (ftfont_drive_otf):
      * keyboard.c (echo_add_key, read_decoded_event_from_main_queue)
      (menu_bar_items, tool_bar_items):
      * sound.c (Fplay_sound_internal):
      * xdisp.c (load_overlay_strings, dump_glyph_row):
      Use an ordinary auto buffer rather than alloca, since the
      allocation size is fixed and small.
      * ftfont.c: Include <c-strcase.h>.
      (matching_prefix): New function.
      (get_adstyle_property): Use it, to avoid need for alloca.
      * keyboard.c (echo_add_key):
      * keymap.c (describe_map): Use ptrdiff_t, not int.
      * keyboard.c (echo_add_key): Prefer sizeof to strlen.
      * keymap.c (Fdescribe_buffer_bindings): Use SBYTES, not SCHARS,
      when counting bytes.
      * lisp.h (xlispstrdupa): Remove, replacing with ...
      (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.
