* Simplify and avoid signal-handling races.Paul Eggert2012-09-231-37/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * nt/inc/ms-w32.h (emacs_raise): New macro. * src/alloc.c (die): * src/sysdep.c (emacs_abort) [HAVE_NTGUI]: Avoid recursive loop if there's a fatal error in the function itself. * src/atimer.c (pending_atimers): * src/blockinput.h: Don't include "atimer.h"; no longer needed. (interrupt_input_pending): Remove. All uses removed. pending_signals now counts both atimers and ordinary interrupts. This is less racy than having three separate pending-signal flags. (block_input, unblock_input, totally_unblock_input, unblock_input_to) (input_blocked_p): Rename from their upper-case counterparts BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO, INPUT_BLOCKED_P, and turn into functions. All uses changed. This makes it easier to access volatile variables more accurately. (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input (). (input_blocked_p): Prefer this to 'interrupt_input_blocked', as that's more reliable if the code is buggy and sets interrupt_input_blocked to a negative value. All uses changed. * src/atimer.c (deliver_alarm_signal): Remove. No need to deliver this to the parent; any thread can handle this signal now. All uses replaced by underlying handler. * src/atimer.c (turn_on_atimers): * src/dispnew.c (handle_window_change_signal): * src/emacs.c (handle_danger_signal): * src/keyboard.c (kbd_buffer_get_event): Don't reestablish signal handler; not needed with sigaction. * src/blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT) (UNBLOCK_INPUT_TO): Rework to avoid unnecessary accesses to volatile variables. (UNBLOCK_INPUT_TO): Now a function. (totally_unblock_input, unblock_input): New decls. * src/data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c (init_data): Remove. Necessary stuff now done in init_signal. * src/emacs.c, src/xdisp.c: Include "atimer.h", since we invoke atimer functions. * src/emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c. (fatal_error_code): Remove; no longer needed. (terminate_due_to_signal): Rename from fatal_error_backtrace, since it doesn't always backtrace. All uses changed. No need to reset signal to default, since sigaction and/or die does that for us now. Use emacs_raise (FOO), not kill (getpid (), FOO). (main): Check more-accurately whether we're dumping. Move fatal-error setup to sysdep.c * src/floatfns.c: Do not include "syssignal.h"; no longer needed. * src/gtkutil.c (xg_get_file_name, xg_get_font): Remove no-longer-needed signal-mask manipulation. * src/keyboard.c, src/process.c (POLL_FOR_INPUT): Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined. * src/keyboard.c (read_avail_input): Remove. All uses replaced by gobble_input. (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code. (kbd_buffer_store_event_hold, gobble_input): (record_asynch_buffer_change) [USABLE_SIGIO]: (store_user_signal_events): No need to mess with signal mask. (gobble_input): If blocking input and there are terminals, simply set pending_signals to 1 and return. All hooks changed to not worry about whether input is blocked. (process_pending_signals): Clear pending_signals before processing them, in case a signal comes in while we're processing. By convention callers now test pending_signals before calling us. (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input): New functions, to support changes to blockinput.h. (handle_input_available_signal): Now extern. (reinvoke_input_signal): Remove. All uses replaced by handle_async_input. (quit_count): Now volatile, since a signal handler uses it. (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All callers changed. Block SIGINT only if not already blocked. Clear sigmask reliably, even if Fsignal returns, which it can. Omit unnecessary accesses to volatile var. (quit_throw_to_read_char): No need to restore sigmask. * src/keyboard.c (gobble_input, handle_user_signal): * src/process.c (wait_reading_process_output): Call signal-handling code rather than killing ourselves. * src/lisp.h: Include <float.h>, for... (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication. (pending_signals): Now volatile. (syms_of_data): Now const if IEEE floating point. (handle_input_available_signal) [USABLE_SIGIO]: (terminate_due_to_signal, record_child_status_change): New decls. * src/process.c (create_process): Avoid disaster if memory is exhausted while we're processing a vfork, by tightening the critical section around the vfork. (send_process_frame, process_sent_to, handle_pipe_signal) (deliver_pipe_signal): Remove. No longer needed, as Emacs now ignores SIGPIPE. (send_process): No need for setjmp/longjmp any more, since the SIGPIPE stuff is now gone. Instead, report an error if errno is EPIPE. (record_child_status_change): Now extern. PID and W are now args. Return void, not bool. All callers changed. * src/sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]: Remove. All uses removed. This bug should be fixed now in a different way. (wait_for_termination_1): Use waitpid rather than sigsuspend, and record the child status change directly. This avoids the need to futz with the signal mask. (process_fatal_action): Move here from emacs.c. (emacs_sigaction_flags): New function, containing much of what used to be in emacs_sigaction_init. (emacs_sigaction_init): Use it. Block nonfatal system signals that are caught by emacs, to make races less likely. (deliver_process_signal): Rename from handle_on_main_thread. All uses changed. (BACKTRACE_LIMIT_MAX): Now at top level. (thread_backtrace_buffer, threadback_backtrace_pointers): New static vars. (deliver_thread_signal, deliver_fatal_thread_signal): New functions, for more-accurate delivery of thread-specific signals. (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c. (deliver_arith_signal): Handle in this thread, not in the main thread, since it's triggered by this thread. (maybe_fatal_sig): New function. (init_signals): New arg DUMPING so that we can be more accurate about whether we're dumping. Caller changed. Treat thread-specific signals differently from process-general signals. Block all signals while handling fatal error; that's safer. xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal on IEEE hosts. When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored. Ignore SIGPIPE unless batch. (emacs_backtrace): Output backtrace for the appropriate thread, which is not necessarily the main thread. * src/syssignal.h: Include <stdbool.h>. (emacs_raise): New macro. * src/xterm.c (x_connection_signal): Remove; no longer needed now that we use sigaction. (x_connection_closed): No need to mess with sigmask now. (x_initialize): No need to reset SIGPIPE handler here, since init_signals does this for us now. Fixes: debbugs:12471
* Port better to POSIX hosts lacking _setjmp.Paul Eggert2012-09-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols. (_setjmp, _longjmp): Remove. * src/lisp.h: Include <setjmp.h> here, since we use its symbols here. All instances of '#include <setjmp.h>' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler. Fixes: debbugs:12446
* Remove unread-command-char.Stefan Monnier2012-09-121-1/+1
| | | | | | | | | | | | | | | | | | | * src/keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p) (Fdiscard_input, quit_throw_to_read_char, init_keyboard) (syms_of_keyboard): Remove support for unread-command-char. * lisp/emacs-lisp/debug.el (debugger-outer-unread-command-char, debug) (debugger-env-macro): Remove support for unread-command-char. * lisp/ehelp.el (with-electric-help): Accept functions in electric-help-form-to-execute. (electric-help-execute-extended, electric-help-ctrl-x-prefix): Use it. And replace unread-command-char -> unread-command-events. * lisp/subr.el (set-temporary-overlay-map): Minimize slightly the impact of the temporary map re-appearing on emulation-mode-map-alists. * lisp/emacs-lisp/edebug.el (def-edebug-form-spec): Remove, it's been broken since 22.1.
* Discard killed buffers from deleted window and frame objects.Dmitry Antipov2012-09-111-3/+5
| | | | | | | | | | | | | This reduces an amount of references to killed buffers and helps GC to reclaim them faster. * alloc.c (discard_killed_buffers): New function. (mark_object): Use it for deleted windows and frames. (mark_object): If symbol's value is set up for a killed buffer or deleted frame, restore it's global binding. * data.c (swap_in_global_binding): Add GC notice. (swap_in_symval_forwarding): Use convenient set_blv_where. * window.c (wset_next_buffers, wset_prev_buffers): Move ... * window.h: ... to here.
* Simplify, document, and port floating-point.Paul Eggert2012-09-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The porting part of this patch fixes bugs on non-IEEE platforms with frexp, ldexp, logb. * admin/CPP-DEFINES (HAVE_CBRT, HAVE_LOGB, logb): Remove. * configure.ac (logb, cbrt): Do not check for these functions, as they are not being used. * doc/lispref/numbers.texi (Float Basics, Arithmetic Operations, Math Functions): Document that / and mod (with floating point arguments), along with asin, acos, log, log10, expt and sqrt, return special values instead of signaling exceptions. (Float Basics): Document that logb operates on the absolute value of its argument. (Math Functions): Document that (log ARG BASE) also returns NaN if BASE is negative. Document that (expt X Y) returns NaN if X is a finite negative number and Y a finite non-integer. * etc/NEWS: Document NaNs versus signaling-error change. * src/data.c, src/lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error): Now static. * src/floatfns.c: Simplify discussion of functions that Emacs doesn't support, by removing commented-out code and briefly listing the C89 functions excluded. The commented-out stuff was confusing maintenance, e.g., we thought we needed cbrt but it was commented out. (logb): Remove decl; no longer needed. (isfinite): New macro, if not already supplied. (isnan): Don't replace any existing macro. (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp are present on all C89 platforms. (Ffrexp): Do not special-case zero, as frexp does the right thing for that case. (Flogb): Do not use logb, as it doesn't have the desired meaning on hosts that use non-base-2 floating point. Instead, stick with frexp, which is C89 anyway. Do not pass an infinity or a NaN to frexp, to avoid getting an unspecified result.
* Assume C89 or later for math functions.Paul Eggert2012-09-091-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the code, and makes it a bit smaller and faster, and (most important) makes it easier to clean up signal handling since we can stop worring about floating-point exceptions in library code. That was a problem before C89, but the problem went away many years ago on all practical Emacs targets. * configure.ac (frexp, fmod): Remove checks for these functions, as we now assume them. (FLOAT_CHECK_DOMAIN, HAVE_INVERSE_HYPERBOLIC, NO_MATHERR) (HAVE_EXCEPTION): Remove; no longer needed. * admin/CPP-DEFINES (HAVE_FMOD, HAVE_FREXP, FLOAT_CHECK_DOMAIN) (HAVE_INVERSE_HYPERBOLIC, NO_MATHERR): Remove. * src/data.c, src/image.c, src/lread.c, src/print.c: Don't include <math.h>; no longer needed. * src/data.c, src/floatfns.c (IEEE_FLOATING_POINT): Don't worry that it might be autoconfigured, as that never happens. * src/data.c (fmod): * src/doprnt.c (DBL_MAX_10_EXP): * src/print.c (DBL_DIG): Remove. C89 or later always defines these. * src/floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN) (in_float, float_error_arg, float_error_arg2, float_error_fn_name) (arith_error, domain_error, domain_error2): Remove all this pre-C89 cruft. Do not include <errno.h> as that's no longer needed -- we simply return what C returns. All uses removed. (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with the wrapped code. (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2): Remove. All uses expanded, as these macros are no longer used more than once and are now more trouble than they're worth. (Ftan): Use tan, not sin / cos. (Flogb): Assume C89 frexp. (fmod_float): Assume C89 fmod. (matherr) [HAVE_MATHERR]: Remove; no longer needed. (init_floatfns): Remove. All uses removed.
* Fix doc of local-variable-if-set-p.Chong Yidong2012-09-071-6/+6
| | | | | | | * doc/lispref/variables.texi (Creating Buffer-Local): Fix description of local-variable-if-set-p. * src/data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
* Signal-handler cleanup.Paul Eggert2012-09-061-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emacs's signal handlers were written in the old 4.2BSD style with sigblock and sigmask and so forth, and this led to some inefficiencies and confusion. Rewrite these to use pthread_sigmask etc. without copying signal sets around. Also, get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and 'signal', and instead use functions that do not attempt to take over the system name space. This patch causes Emacs's text segment to shrink by 0.7% on my platform, Fedora 17 x86-64. * configure.ac (PTY_OPEN, PTY_TTY_NAME_SPRINTF): Adjust to syssignal.h changes. (SIGNAL_H_AB): Remove; no longer needed. * src/alloc.c, src/emacsgtkfixed.c, src/nsfns.m, src/widget.c, src/xmenu.c: Do not include <signal.h> or "syssignal.h", as these modules do not use signals. * src/atimer.c, src/callproc.c, src/data.c, src/dispnew.c, src/emacs.c: * src/floatfns.c, src/gtkutil.c, src/keyboard.c, src/process.c, src/sound.c: * src/sysdep.c, src/term.c, src/xterm.c: Do not include <signal.h>, as "syssignal.h" does that for us now. * src/atimer.c (sigmask_atimers): New function. (block_atimers, unblock_atimers): New functions, replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS. All uses replaced. * src/conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>; no longer needed here. * src/emacs.c (main): Inspect existing signal handler with sigaction, so that there's no need to block and unblock SIGHUP. * src/sysdep.c (struct save_signal): New member 'action', replacing old member 'handler'. (save_signal_handlers, restore_signal_handlers): Use sigaction instead of 'signal' to save and restore. (get_set_sighandler, set_sighandler) [!WINDOWSNT]: New function. All users of 'signal' modified to use set_sighandler if they're writeonly, and to use sys_signal if they're read+write. (emacs_sigaction_init, forwarded_signal): New functions. (sys_signal): Remove. All uses replaced by calls to sigaction and emacs_sigaction_init, or by direct calls to 'signal'. (sys_sigmask) [!__GNUC__]: Remove; no longer needed. (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove; all uses replaced by pthread_sigmask etc. calls. * src/syssignal.h: Include <signal.h>. (emacs_sigaction_init, forwarded_signal): New decls. (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t. (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask. (sigmask, sys_sigmask): Remove; no longer needed. (sigpause): Remove. All uses replaced by its definiens, sigsuspend. (sigblock, sigunblock, sigfree): (sigsetmask) [!defined sigsetmask]: Remove. All uses replaced by pthread_sigmask. (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN) no longer need to be replaced, and its typical old uses are now done via emacs_sigaction_init and sigaction. (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls. (sys_sigdel): Remove; unused. (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef. Fixes: debbugs:12327
* Fix race conditions with signal handlers and errno.Paul Eggert2012-09-051-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Be more systematic about preserving errno whenever a signal handler returns, even if it's not in the main thread. Do this by renaming signal handlers to distinguish between signal delivery and signal handling. All uses changed. * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler. * data.c (deliver_arith_signal): Rename from arith_error. * dispnew.c (deliver_window_change_signal): Rename from window_change_signal. * emacs.c (deliver_error_signal): Rename from fatal_error_signal. (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal. * keyboard.c (deliver_input_available_signal): Rename from input_available_signal. (deliver_user_signal): Rename from handle_user_signal. (deliver_interrupt_signal): Rename from interrupt_signal. * process.c (deliver_pipe_signal): Rename from send_process_trap. (deliver_child_signal): Rename from sigchld_handler. * atimer.c (handle_alarm_signal): * data.c (handle_arith_signal): * dispnew.c (handle_window_change_signal): * emacs.c (handle_fatal_signal, handle_danger_signal): * keyboard.c (handle_input_available_signal): * keyboard.c (handle_user_signal, handle_interrupt_signal): * process.c (handle_pipe_signal, handle_child_signal): New functions, with the actual signal-handling code taken from the original respective signal handlers, sans the sporadic attempts to preserve errno, since that's now done by handle_on_main_thread. * atimer.c (alarm_signal_handler): Remove unnecessary decl. * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft. * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Move to sysdep.c. (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Move initialization of main_thread to sysdep.c's init_signals. * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for our usage, and simplifies the mainline code. (record_child_status_change): New static function, as a helper for handle_child_signal, and with most of the old child handler's contents. (CAN_HANDLE_MULTIPLE_CHILDREN): New constant. (handle_child_signal): Use the above. * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Moved here from emacs.c. (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it; code moved here from emacs.c's main function. * sysdep.c, syssignal.h (handle_on_main_thread): New function, replacing the old SIGNAL_THREAD_CHECK. All uses changed. This lets callers save and restore errno properly.
* Simplify redefinition of 'abort' (Bug#12316).Paul Eggert2012-09-041-18/+18
| | | | | | | | | | | | | | | | | | | | | | Do not try to redefine the 'abort' function. Instead, redo the code so that it calls 'emacs_abort' rather than 'abort'. This removes the need for the NO_ABORT configure-time macro and makes it easier to change the abort code to do a backtrace. * configure.ac (NO_ABRT): Remove. * admin/CPP-DEFINES (NO_ABORT): Remove. * nt/inc/ms-w32.h (w32_abort) [HAVE_NTGUI]: Remove. * src/.gdbinit: Just stop at emacs_abort, not at w32_abort or abort. * src/emacs.c (abort) [!DOS_NT && !NO_ABORT]: Remove; sysdep.c's emacs_abort now takes its place. * src/lisp.h (emacs_abort): New decl. All calls from Emacs code to 'abort' changed to use 'emacs_abort'. * src/msdos.c (dos_abort) [defined abort]: Remove; not used. (abort) [!defined abort]: Rename to ... (emacs_abort): ... new name. * src/sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking the place of the old 'abort' in emacs.c. * src/w32.c, src/w32fns.c (abort): Do not #undef. * src/w32.c (emacs_abort): Rename from w32_abort.
* * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.Paul Eggert2012-08-271-25/+24
| | | | | | | | | | | | | | | | | | * composite.c (find_composition, composition_gstring_p) (composition_reseat_it, find_automatic_composition): * data.c (let_shadows_buffer_binding_p) (let_shadows_global_binding_p, set_internal, make_blv) (Fmake_variable_buffer_local, Fmake_local_variable) (Fmake_variable_frame_local, arithcompare, cons_to_unsigned) (cons_to_signed, arith_driver): * dbusbind.c (xd_in_read_queued_messages): * dired.c (directory_files_internal, file_name_completion): Use bool for booleans. * dired.c (file_name_completion): * process.h (fd_callback): Omit int (actually boolean) argument. It wasn't being used. All uses changed. * composite.h, lisp.h: Reflect above API changes.
* Remove unused external symbols.Paul Eggert2012-08-261-4/+2
| | | | | | | | | | | * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector): * window.c (Qwindow_valid_p, decode_valid_window): Now static, not extern. * data.c (Qinterval): Remove; unused. (syms_of_data): Do not define 'interval'. * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons): * window.h (decode_valid_window): Remove decls.
* Inline getter and setter functions for per-buffer values.Dmitry Antipov2012-08-201-8/+8
| | | | | | | * buffer.h (per_buffer_default, set_per_buffer_default) (per_buffer_value, set_per_buffer_value): New functions. (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove. * buffer.c, data.c: Adjust users.
* * data.c (set_internal): Don't use set_blv_found.Andreas Schwab2012-08-191-3/+3
| | | | (Fkill_local_variable): Likewise.
* * buffer.h (BSET): Remove.Paul Eggert2012-08-171-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace all uses with calls to new setter functions.

* Remove unnecessary casts involving pointers.Paul Eggert2012-08-031-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | These casts are no longer needed now that we assume C89 or later, since they involve casting to or from void *. * alloc.c (make_pure_string, make_pure_c_string, pure_cons) (make_pure_float, make_pure_vector): * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): * macros.c (Fstart_kbd_macro): * menu.c (find_and_return_menu_selection): * minibuf.c (read_minibuf_noninteractive): * sysdep.c (closedir): * xdisp.c (x_produce_glyphs): * xfaces.c (compare_fonts_by_sort_order): * xfns.c (x_real_positions, select_visual): * xselect.c (x_stop_queuing_selection_requests) (x_get_window_property, x_get_window_property_as_lisp_data): * xterm.c (x_set_frame_alpha, x_find_modifier_meanings): Remove unnecessary pointer casts. * alloc.c (record_xmalloc): New function. * lisp.h (record_xmalloc): New decl. (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts more like a function. This is because the pointer cast is not needed. All uses changed. * print.c (print_string, print_error_message): Avoid length recalc.
* Use INTERNAL_FIELD for symbols.Dmitry Antipov2012-08-011-17/+17
| | | | | | | | * src/lisp.h (SVAR): New macro. Adjust users. * src/alloc.c, src/bytecode.c, src/cmds.c, src/data.c, src/doc.c, src/eval.c: * src/fns.c, src/keyboard.c, src/lread.c, src/xterm.c: Users changed. * admin/coccinelle/symbol.cocci: Semantic patch to replace direct access to Lisp_Object members of struct Lisp_Symbol to SVAR.

| | | | | This no-op macro hasn't been needed for many years. * src/regex.c (SWITCH_ENUM_CAST) [!emacs]: Likewise.
* * lisp.h (LISP_INT_TAG, LISP_INT1_TAG, LISP_STRING_TAG): Remove.Paul Eggert2012-07-291-1/+1
| | | | | | These macros are confusing and no longer need to be defined, as the enum values now suffice. Each use replaced with definiens. (Lisp_Int1, Lisp_String): Define directly; this is clearer.
* Autoload more carefully from Lisp. Follow aliases for function properties.Stefan Monnier2012-07-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/subr.el (autoloadp): New function. (symbol-file): Use it. (function-get): New function. * lisp/emacs-lisp/macroexp.el (macroexp--expand-all): Use function-get and autoload-do-load. * lisp/emacs-lisp/lisp-mode.el (lisp-font-lock-syntactic-face-function) (lisp-indent-function): * lisp/emacs-lisp/gv.el (gv-get): * lisp/emacs-lisp/edebug.el (get-edebug-spec, edebug-basic-spec): * lisp/emacs-lisp/byte-opt.el (byte-optimize-form): * lisp/emacs-lisp/bytecomp.el (byte-compile-arglist-warn): * lisp/emacs-lisp/autoload.el (make-autoload, autoload-print-form): Use function-get. * lisp/emacs-lisp/cl.el: Don't propagate function properties any more. * src/eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp, add argument, tune behavior, and adjust all callers. * lisp/speedbar.el (speedbar-add-localized-speedbar-support): * lisp/emacs-lisp/disass.el (disassemble-internal): * lisp/desktop.el (desktop-load-file): * lisp/help-fns.el (help-function-arglist, find-lisp-object-file-name) (describe-function-1): * lisp/emacs-lisp/find-func.el (find-function-noselect): * lisp/emacs-lisp/elp.el (elp-instrument-function): * lisp/emacs-lisp/advice.el (ad-has-proper-definition): * lisp/apropos.el (apropos-safe-documentation, apropos-macrop): * lisp/emacs-lisp/debug.el (debug-on-entry): * lisp/emacs-lisp/cl-macs.el (cl-compiler-macroexpand): * lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): * lisp/calc/calc.el (name): Use autoloadp & autoload-do-load.
* * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.Paul Eggert2012-07-191-1/+1
| | | | | | | | (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from 'for_each_per_buffer_object_at'. All uses changed. It's better to use upper-case for macros that cannot be implemented as functions, to give the reader a clue that they're special.
* New macro to iterate over all buffers, miscellaneous cleanups.Dmitry Antipov2012-07-191-1/+1
| | | | | | | | | | | | | * lisp.h (all_buffers): Remove declaration. * buffer.h (all_buffers): Add declaration, with comment.

Remove obsolete comment.
* Return more descriptive data from Fgarbage_collect.Dmitry Antipov2012-07-181-6/+8
| | | | | | | | | | | | | | | | | | | | | Suggested by Stefan Monnier in http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00369.html. * src/alloc.c (bounded_number): New function. (total_buffers, total_vectors): New variable. (total_string_size): Rename to total_string_bytes, adjust users. (total_vector_size): Rename to total_vector_bytes, adjust users. (sweep_vectors): Account total_vectors and total_vector_bytes. (Fgarbage_collect): New return value. Adjust documentation. (gc_sweep): Account total_buffers.

(syms_of_data): Initialize them. * src/lisp.h (Qinterval, Qsymbol, Qstring, Qmisc, Qvector, Qfloat) (Qcons, Qbuffer): New declarations. * lisp/emacs-lisp/chart.el (chart-emacs-storage): Change to reflect new format of data returned by Fgarbage_collect.
* Optimize pure C strings initialization.Dmitry Antipov2012-07-101-3/+3
| | | | | | | | | | | | | * lisp.h (make_pure_string): Fix prototype. (build_pure_c_string): New function, defined as static inline. This provides a better opportunity to optimize away calls to strlen when the function is called with compile-time constant argument. * alloc.c (make_pure_c_string): Fix comment. Change to add nchars argument, adjust users accordingly. Use build_pure_c_string where appropriate. * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c, * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c, * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
* More xmalloc and related cleanup.Paul Eggert2012-07-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c: * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c: * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c: * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c: * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c: * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c: * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c: * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c: * xterm.c: Omit needless casts involving void * pointers and allocation. Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))", as the former is more robust if P's type is changed. Prefer xzalloc to xmalloc + memset 0. Simplify malloc-or-realloc to realloc. Don't worry about xmalloc returning a null pointer. Prefer xstrdup to xmalloc + strcpy. * editfns.c (Fmessage_box): Grow message_text by at least 80 when growing it. * keyboard.c (apply_modifiers_uncached): Prefer local array to alloca of a constant.
* Get rid of all the manual purecopy calls in menu-bar definitions.Stefan Monnier2012-06-271-1/+1
| | | | | | | | | | | | * lisp/loadup.el (purify-flag): Pre-grow the hash-table to reduce the memory use. * lisp/bindings.el (bindings--define-key): New function. * lisp/vc/vc-hooks.el, lisp/replace.el, lisp/menu-bar.el: * lisp/international/mule-cmds.el, lisp/emacs-lisp/lisp-mode.el: * lisp/buff-menu.el, lisp/bookmark.el: * bindings.el: Use it to purecopy define-key bindings. * src/fns.c (maybe_resize_hash_table): Output message when growing the purify-hashtable.
* Use sprintf return value instead of invoking strlen on result.Paul Eggert2012-06-251-9/+6
| | | | | | | | | | | | | | | | | | | | | In the old days this wasn't portable, since some sprintf implementations returned char *. But they died out years ago and Emacs already assumes sprintf returns int. Similarly for float_to_string. This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64. * ccl.c (ccl_driver): * character.c (string_escape_byte8): * data.c (Fnumber_to_string): * doprnt.c (doprnt): * print.c (print_object): * xdisp.c (message_dolog): * xfns.c (syms_of_xfns): Use sprintf or float_to_string result to avoid need to call strlen. * data.c (Fnumber_to_string): Use make_unibyte_string, since the string must be ASCII. * lisp.h, print.c (float_to_string): Now returns int length. * term.c (produce_glyphless_glyph): Use sprintf result rather than recomputing it.
* Switch from NO_RETURN to C11's _Noreturn.Paul Eggert2012-06-241-2/+1
| | | | Fixes: debbugs:11750
* * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:Dmitry Antipov2012-06-191-1/+1
| | | | | | | * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c: * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct access to `contents' member of Lisp_Vector objects with AREF and ASET where appropriate.
* Fix return value of `defun' and un-define it.Stefan Monnier2012-06-181-5/+10
| | | | | | | | | * src/data.c (Fdefalias): Return `symbol'. * doc/lispref/functions.texi (Defining Functions): * doc/lispref/macros.texi (Defining Macros): Un-define the return value of `defun', `defmacro' and `defalias'. Fixes: debbugs:11686
* USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)Paul Eggert2012-06-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | * alloc.c (make_number) [!defined make_number]: Remove, as lisp.h always defines this now. (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now. (roundup_size): Verify that it is a power of 2. * data.c (Fmake_variable_buffer_local, Fmake_local_variable): * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO. * lisp.h (USE_LSB_TAG): Allow the builder to compile with -DUSE_LSB_TAG=0, to override the automatically-selected default. USE_LSB_TAG now is always defined to be either 0 or 1. All uses changed. (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the code works fine either way, and efficiency is not a concern here, as the union type is for debugging, not for production. (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]: Use an inline function on all platforms when using the union type, since this is simpler and 'static inline' can be used portably within Emacs now. (LISP_INITIALLY_ZERO): New macro. (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove. (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
* * lisp/emacs-lisp/byte-run.el (defmacro, defun): Move from C.Stefan Monnier2012-05-291-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (macro-declaration-function): Move var from C code. (macro-declaration-function): Define function with defalias. * lisp/emacs-lisp/macroexp.el (macroexpand-all-1): * lisp/emacs-lisp/cconv.el (cconv-convert, cconv-analyse-form): * lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Don't handle defun/defmacro any more. * lisp/emacs-lisp/bytecomp.el (byte-compile-arglist-signature): Provide fallback for unknown arglist. (byte-compile-arglist-warn): Change calling convention. (byte-compile-output-file-form): Move print-vars binding. (byte-compile-output-docform): Simplify accordingly.

(byte-compile-file-form-defalias): Use byte-compile-file-form-defmumble. (byte-compile-defalias-warn): Remove. * src/eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function): Move to byte-run.el. (Fautoload): Do the hash-doc more carefully. * src/data.c (Fdefalias): Purify definition, except for keymaps. (Qdefun): Move from eval.c. * src/lisp.h (Qdefun): Remove. * src/lread.c (read1): Tiny simplification. * lib-src/make-docfile.c: Improve comment style. (search_lisp_doc_at_eol): New function.
