* Rework C source files to avoid ^(Paul Eggert2016-03-101-4/+4
| | | | | | | | 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.

* Avoid crashes in coding_inherit_eol_typeEli Zaretskii2015-10-031-0/+2
| | | | | | * src/coding.c (coding_inherit_eol_type): Check the validity of the arguments. Suggested by Andreas Schwab <schwab@linux-m68k.org>. (Bug#21602)
* Omit unnecessary \ before paren in C docstringsPaul Eggert2015-09-161-2/+2
| | | | | | | | | 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 ).
* Add -Wswitch to --enable-gcc-warningsPaul Eggert2015-09-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Fix uninitalized value in encode_coding_objectPaul Eggert2015-07-271-1/+5
| | | | | | * 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.

* Treat batch stdout/stderr like standard displayPaul Eggert2015-05-311-1/+2
| | | | | | | | | | | | | | | | | | | | 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.
* Remove unused DEFSYMsPaul Eggert2015-05-311-11/+0
| | | | | | | | | | | | | Remove DEFSYMs that aren't used at the C level. Also: * src/decompress.c (Qzlib_dll): * src/font.c (Qunicode_sip): * src/frame.c (Qtip_frame): * src/ftfont.c (Qserif): * src/gnutls.c (Qgnutls_dll): * src/xml.c (Qlibxml2_dll): Move from here ... * src/w32fns.c (syms_of_w32fns): ... to here, as these are used only on MS-Windows.

(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.

(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.

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.
