* Remove unused DEFSYMsPaul Eggert2015-05-311-1/+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.
* Don't misencode C-generated messagesPaul Eggert2015-05-301-2/+1
| | | | | | | | | | | | | | | | | | Also, be more consistent about calls to 'Fmessage' vs 'message'. * src/alloc.c (Fgc_status): Prefer AUTO_STRING to build_string for Fmessage call. * src/data.c (Fmake_variable_buffer_local) (Fmake_local_variable, Fmake_variable_frame_local): * src/doc.c (store_function_docstring): Use Fmessage, not message, since the argument can contain non-ASCII characters, and this can cause the resulting message to be incorrectly encoded for the current environment. * src/fns.c (maybe_resize_hash_table): * src/xselect.c (x_clipboard_manager_save_all): Use message, not Fmessage, since Fmessage's power isn't needed here. * src/process.c (Fmake_network_process): Reword message to avoid %s. * src/xdisp.c (vmessage): Document restrictions on message contents. (message_nolog) [false]: Remove unused code.
* Omit -Wstrict-overflow workaround in GCC 5Paul Eggert2015-04-291-2/+2
| | | | | * src/process.c: Remove workaround for GCC -Wstrict-overflow bug if it's GCC 5 or later, as the bug appears to be fixed in GCC 5.1.
* Don't freeze with unreadable processesPaul Eggert2015-04-251-18/+22
| | | | | | | | | | | Don't freeze if an exiting process can't be read from. (Bug#19860). This fixes a bug I introduced in 2014-07-08T07:24:07Z@eggert@cs.ucla.edu "* process.c: Add sanity checks for file descriptors." Dmitry Gutov did most of the legwork in finding the problem. * src/process.c (wait_reading_process_output): Treat non-running processes that can't be read from the same as other non-running processes.
* Avoid non-nil current-load-list at startupGlenn Morris2015-04-201-34/+35
| | | | | * src/process.c (init_process_emacs): Move Fprovide statement... (syms_of_process): ... to here.

(create_process): Respect p->stderrproc. (Fmake_pipe_process): New function. (Fmake_process): Add new keyword argument :stderr. (wait_reading_process_output): Specially handle a pipe process when it gets an EOF. (syms_of_process): Register Qpipe and Smake_pipe_process. * doc/lispref/processes.texi (Asynchronous Processes): Document `make-pipe-process' and `:stderr' keyword of `make-process'. * lisp/subr.el (start-process): Suggest to use `make-process' handle standard error separately. * test/automated/process-tests.el (process-test-stderr-buffer) (process-test-stderr-filter): New tests. * etc/NEWS: Mention new process type `pipe' and its usage with the `:stderr' keyword of `make-process'.
* Assume !BROKEN_NON_BLOCKING_CONNECTPaul Eggert2015-03-271-18/+9
| | | | | | | | From a suggestion by Eli Zaretskii in: http://lists.gnu.org/archive/html/emacs-devel/2015-03/msg00824.html * process.c (NON_BLOCKING_CONNECT): Simplify by assuming that BROKEN_NON_BLOCKING_CONNECT is not defined. (SELECT_CAN_DO_WRITE_MASK): Remove, and assume it's now true.

* Minor refactoring of new Fmake_process codePaul Eggert2015-03-231-36/+32
| | | | | * process.c (Fmake_process): Refactor to avoid call to Flength, to avoid cast to 'char **', and to reduce indenting and reuse of locals.
* Generalize start-process with keyword argsDaiki Ueno2015-03-231-43/+132
| | | | | | | | | | | | | | | | * src/process.c (Fmake_process): New function. (create_process, create_pty): Check p->pty_flag instead of Vprocess_connection_type. (syms_of_process): Register QCcommand, QCconnection_type, Qpty, Qpipe, and Smake_process. Unregister Sstart_process. * lisp/subr.el (start-process): New function, ported from the C implementation. * doc/lispref/processes.texi (Asynchronous Processes): Mention `make-process'. * etc/NEWS: Mention `make-process'.

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.

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.

(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.

* | Simplify stack-allocated Lisp objects, and make them more portable.Paul Eggert2014-09-291-21/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The build_local_string macro was used in two ways: (1) string literals for which scoped allocation suffices, and (2) file name components, where it's not safe in general to assume bounded-size ASCII data. Simplify by defining a new macro SCOPED_STRING that allocates a block-scope string, and by using SCOPED_STRING for (1) and build_string for (2). Furthermore, actually use stack allocation only for objects known to have sufficient alignment. This simpler implementation means Emacs can make USE_STACK_LISP_OBJECTS the default unless GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS. * lisp.h (GCALIGNED): Align even if !USE_STACK_LISP_OBJECTS, for fewer differences among implementations. (struct Lisp_String): Now GCALIGNED. (USE_STACK_LISP_OBJECTS): Default to true, since the implementation no longer insists on a nonempty GCALIGNED. But make it false if GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS. (SCOPED_CONS_INITIALIZER): Remove, since it's no longer needed separately. Move definiens to scoped_cons. The old definition was incorrect when GCALIGNED was defined to be empty. (union Aligned_String): New type. (USE_STACK_CONS, USE_STACK_STRING): New constants, so that the implementation ports to compilers that don't align strictly enough. Don't worry about the union sizes; it's not worth bothering about. (scoped_cons, scoped_list1, scoped_list3, scoped_list4): Rewrite using USE_STACK_CONS. (scoped_cons): Assume the use of union Aligned_Cons. (lisp_string_size, make_local_string, build_local_string): Remove. Unless otherwise specified, all callers of build_local_string changed to use SCOPED_STRING. (SCOPED_STRING): New macro. * data.c (wrong_choice): * menu.c (single_menu_item): * process.c (Fformat_network_address): Hoist use of SCOPED_STRING out of a scope, so that its returned object lives long enough. * fileio.c (Fexpand_file_name): Use build_string, not SCOPED_STRING, as the string might be long or might not be ASCII.

(scoped_cons) [USE_STACK_LISP_OBJECTS]: Use it. (USE_LOCAL_ALLOCA): Remove. (local_cons, local_list1, local_list2, local_list3, local_list4): Remove. Stack overflow checking makes them too slow.
