* * atimer.c (toplevel) [HAVE_TIMERFD]: Include errno.h.Dmitry Antipov2014-08-011-6/+21
| | | | | | | (timerfd_callback): Ignore weird events with no data. Add tight assertions and comments. (init_atimer) [HAVE_TIMERFD]: Add environment variable to optionally disabletimerfd-based timer. Use TFD_NONBLOCK for timer descriptor.
* Simplify timerfd configuration and fix some minor glitches.Paul Eggert2014-07-311-71/+53
| | | | | | | | | | | | | | | | | * configure.ac (HAVE_TIMERFD): Define only if TFD_CLOEXEC works, since the code leaked file descriptors to children when !TFD_CLOEXEC. (HAVE_TIMERFD_CLOEXEC): Remove; no longer used. * m4/clock_time.m4 (gl_CLOCK_TIME): Don't check for clock_getres. This reverts the previous change to this file, so it matches gnulib again. * src/atimer.c (TIMERFD_CREATE_FLAGS): Remove; we now assume TFD_CLOEXEC. (alarm_timer, alarm_timer_ok, set_alarm, init_atimer): Fall back on timer_create if timerfd_create fails at runtime. (resolution) [HAVE_CLOCK_GETRES]: Remove; we now rely on the kernel primitives to do resolution. All uses removed. (timerfd) [!HAVE_TIMERFD]: Define to be -1, for convenience. (turn_on_atimers): Clear timer_create-based timers too, for consistency.
* Fix Gnus-related issues reported by David Kastrup <dak@gnu.org> inDmitry Antipov2014-07-281-1/+22
| | | | | | | | | <http://lists.gnu.org/archive/html/emacs-devel/2014-07/msg00370.html>. * atimer.c (timerfd_callback): Always read expiration data. Add comment. (turn_on_atimers) [HAVE_TIMERFD]: Disarm timerfd timer. * process.c (add_timer_wait_descriptor): Add timer descriptor to input_wait_mask and non_process_wait_mask as well.
* On GNU/Linux, use timerfd for asynchronous timers.Dmitry Antipov2014-07-281-13/+142
| | | | | | | | | | | | | | | | | | | | | | | * configure.ac (toplevel): Check whether GNU/Linux-specific timerfd functions and macros are available. * m4/clock_time.m4 (gl_CLOCK_TIME): Check for clock_getres as well. * src/atimer.c (toplevel) [HAVE_TIMERFD]: Include sys/timerfd.h. (toplevel): Rename alarm_timer_ok to special_timer_available. [HAVE_TIMERFD]: Declare timerfd. [HAVE_CLOCK_GETRES]: Declare resolution. (start_atimer) [HAVE_CLOCK_GETRES]: Round up timestamp to system timer resolution. (set_alarm) [HAVE_TIMERFD]: Use timerfd_settime. (timerfd_callback) [HAVE_TIMERFD]: New function. (atimer_result, debug_timer_callback, Fdebug_timer_check) [ENABLE_CHECKING]: New function for the sake of automated tests. (init_atimer) [HAVE_TIMERFD]: Setup timerfd. [HAVE_CLOCK_GETRES]: Likewise for system timer resolution. [ENABLE_CHECKING]: Defsubr test function. * src/atimer.h (timerfd_callback) [HAVE_TIMERFD]: Add prototype. * src/lisp.h (add_timer_wait_descriptor) [HAVE_TIMERFD]: Likewise. * src/process.c (add_timer_wait_descriptor) [HAVE_TIMERFD]: New function. * test/automated/timer-tests.el (timer-tests-debug-timer-check): New test.
* * atimer.c (set_alarm) [HAVE_ITIMERSPEC]: Use TIMER_ABSTIMEDmitry Antipov2014-07-251-1/+1
| | | | because atimer expiration is absolute rather than relative.
* Don't let SIGINT handling block SIGCHLD indefinitely.Paul Eggert2014-05-291-2/+4
| | | | | | | | | | | | | | * atimer.c (block_atimers): * callproc.c (block_child_signal): Block SIGINT too; otherwise, its handler might now unblock signals that it shouldn't. * keyboard.c (read_char): Clear signal mask, since we may be in a SIGINT handler, and many signals may be masked. * keyboard.c (handle_interrupt): * sysdep.c (handle_arith_signal): Clear signal mask instead of just unblocking the signal that was received, since several signals may be blocked at this point. Fixes: debbugs:17561
* Handle sigmask better with nested signal handlers.Paul Eggert2014-03-251-19/+19
| | | | | | | | | | | | | | | | | | | | | | | * atimer.c (sigmask_atimers): Remove. Remaining use rewritten to use body of this function. * atimer.c (block_atimers, unblock_atimers): * callproc.c (block_child_signal, unblock_child_signal): * sysdep.c (block_tty_out_signal, unblock_tty_out_signal): New arg OLDSET. All callers changed. * atimer.c (block_atimers, unblock_atimers): * callproc.c (block_child_signal, unblock_child_signal): * keyboard.c (handle_interrupt): * sound.c (vox_configure, vox_close): Restore the old signal mask rather than unilaterally clearing bits from the mask, in case a handler is running within another handler. All callers changed. * lisp.h, process.c, process.h, term.c: Adjust decls and callers to match new API. * sysdep.c (emacs_sigaction_init): Don't worry about masking SIGFPE; signal handlers aren't supposed to use floating point anyway. (handle_arith_signal): Unblock just SIGFPE rather than clearing mask. Fixes: debbugs:15561

* Simplify EMACS_TIME-related code.Paul Eggert2013-08-271-17/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This portability layer is no longer needed, since Emacs has been using struct timespec as a portability layer for some time. Merge from gnulib, incorporating: 2013-08-27 timespec: new convenience constants and function * src/atimer.h, src/buffer.h, src/dispextern.h, src/xgselect.h: Include <time.h> rather than "systime.h"; that's all that's needed now. * src/dispnew.c: Include <timespec.h> rather than "systime.h"; that's all that's needed now. * src/systime.h (EMACS_TIME): Remove.

In some cases this fixes an unlikely bug when the corresponding int is outside Emacs integer range. All uses changed. * dired.c (directory_files_internal_unwind): * fileio.c (do_auto_save_unwind): * gtkutil.c (pop_down_dialog): * insdel.c (reset_var_on_error): * lread.c (load_unwind): * xfns.c (clean_up_file_dialog): * xmenu.c, nsmenu.m (pop_down_menu): * xmenu.c (cleanup_widget_value_tree): * xselect.c (wait_for_property_change_unwind): Accept pointer and return void, rather than accepting an Emacs save value encapsulating the pointer and returning a dummy object. All uses changed. * editfns.c (Fformat): Update the saved pointer directly via set_unwind_protect_ptr rather than indirectly via make_save_pointer. * eval.c (specpdl_func): Remove. All uses replaced by definiens. (unwind_body): New function. (record_unwind_protect): First arg is now a function returning void, not a dummy Lisp_Object. (record_unwind_protect_ptr, record_unwind_protect_int) (record_unwind_protect_void): New functions. (unbind_to): Support SPECPDL_UNWIND_PTR etc. * fileio.c (struct auto_save_unwind): New type. (do_auto_save_unwind): Use it. (do_auto_save_unwind_1): Remove; subsumed by new do_auto_save_unwind. * insdel.c (struct rvoe_arg): New type. (reset_var_on_error): Use it. * lisp.h (SPECPDL_UNWIND_PTR, SPECPDL_UNWIND_INT, SPECPDL_UNWIND_VOID): New constants. (specbinding_func): Remove; there are now several such functions. (union specbinding): New members unwind_ptr, unwind_int, unwind_void. (set_unwind_protect_ptr): New function. * xselect.c: Remove unnecessary forward decls, to simplify maintenance.
* Timestamp fixes for undo.Paul Eggert2013-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/text.texi (Undo): Document (t . 0) and (t . -1) in buffer-undo-list. * etc/NEWS: Changes to visited-file-modtime, set-visited-file-modtime. * lisp/files.el (clear-visited-file-modtime): Move here from fileio.c. * src/atimer.c (schedule_atimer): * src/fileio.c (Ffile_newer_than_file_p): Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT. * src/buffer.c (buffer-undo-list): Document (t . 0) and (t . -1). * src/fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el. (syms_of_fileio): Remove Sclear_visited_file_name. (Fvisited_file_modtime): Return -1, not (-1 ...), when the visited file doesn't exist; this avoids an ambiguity with negative timestamps. (Fset_visited_file_modtime): Accept -1 and 0 as time-list arg. * src/systime.h (make_emacs_time, invalid_emacs_time): Don't assume struct timespec layout; POSIX doesn't guarantee it. (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove. * src/undo.c (record_first_change): Push (visited-file-modtime) onto undo list rather than reimplementing it by hand, incorrectly.

* Port timers to OpenBSD, plus check for timer failures.Paul Eggert2012-10-031-3/+3
| | | | | | | | | | | | OpenBSD problem reported by Han Boetes. * profiler.c (setup_cpu_timer): Check for failure of timer_settime and/or setitimer. (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER. * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms like OpenBSD, which has timer_settime but does not declare it. OpenBSD does not define SIGEV_SIGNAL, so use that when deciding whether to use itimerspec-related primitives. All uses of HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
* Check more robustly for timer_settime.Paul Eggert2012-09-261-3/+3
| | | | | | | | | | | | | This should fix an OS X build problem reported by Ivan Andrus in <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00671.html>. * admin/merge-gnulib (GNULIB_MODULES): Add timer-time. * configure.ac (gl_THREADLIB): Define to empty, since Emacs does threads its own way. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * m4/timer_time.m4: New file, from gnulib. * src/atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer): Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to call timer_settime.
* Prefer POSIX timers if available.Paul Eggert2012-09-251-6/+31
| | | | | | | They avoid a race if the timer is too close to the current time. * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars. (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available. (init_atimer) [SIGEV_SIGAL]: Initialize them.
* Simplify and avoid signal-handling races.Paul Eggert2012-09-231-43/+8

(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
* Remove configure's --without-sync-input option.Paul Eggert2012-09-161-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When auditing signal-handling in preparation for cleaning it up, I found that SYNC_INPUT has race conditions and would be a real pain to fix. Since it's an undocumented and deprecated configure-time option, now seems like a good time to remove it. Also see <http://bugs.gnu.org/11080#16>. * configure.ac (SYNC_INPUT, BROKEN_SA_RESTART): Remove. * admin/CPP-DEFINES (BROKEN_SA_RESTART, SA_RESTART): Remove. * etc/TODO (Make SYNC_INPUT the default): Remove, as the code now behaves as if SYNC_INPUT is always true. * src/alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal) (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls. (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]: (malloc_hysteresis): (check_depth) [XMALLOC_OVERRUN_CHECK]: (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED) (dont_register_blocks, bytes_used_when_reconsidered) (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc) (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc): [!SYSTEM_MALLOC && !SYNC_INPUT]: Remove. All uses removed. (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different implementation, one that depends on whether the new macro XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT is defined. * src/atimer.c (run_timers, handle_alarm_signal): * src/keyboard.c (pending_signal, poll_for_input_1, poll_for_input) (handle_async_input, process_pending_signals) (handle_input_available_signal, init_keyboard): * src/nsterm.m (ns_read_socket): * src/process.c (wait_reading_process_output): * src/regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK): * src/sysdep.c (emacs_sigaction_init) [SA_RESTART]: (emacs_write): * src/xterm.c (XTread_socket): Assume SYNC_INPUT. * src/conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef. * src/eval.c (handling_signal): Remove. All uses removed. * src/lisp.h (ELSE_PENDING_SIGNALS): Remove. All uses replaced with the SYNC_INPUT version. (reset_malloc_hooks, uninterrupt_malloc, handling_signal): Remove decls. * src/sysdep.c, src/syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Now static. Fixes: debbugs:12450
* Port better to POSIX hosts lacking _setjmp.Paul Eggert2012-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Signal-handler cleanup.Paul Eggert2012-09-061-15/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Eggert2012-09-051-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.Paul Eggert2012-08-231-1/+1
| | | | * atimer.h: Include <stdbool.h>.
* EMACS_TIME simplification (Bug#11875).Paul Eggert2012-07-101-23/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces macros (which typically do not work in GDB) with functions, typedefs and enums, making the code easier to debug. The functional style also makes code easier to read and maintain. * lib-src/profile.c (TV2): Remove no-longer-needed static var. * src/systime.h: Include <sys/time.h> on all hosts, not just if WINDOWSNT, since 'struct timeval' is needed in general. (EMACS_TIME): Now a typedef, not a macro. (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants, not macros. (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P) (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ) (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT) (EMACS_TIME_LE): Now functions, not macros. (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS) (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros, which are not functions. All uses rewritten to use: (make_emacs_time): New function. (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME) (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are not functions. All uses rewritten to use the following, respectively: (emacs_secs_addr, invalid_emacs_time, get_emacs_time) (add_emacs_time, sub_emacs_time): New functions. * src/atimer.c: Don't include <sys/time.h>, as "systime.h" does this. * src/fileio.c (Fcopy_file): * src/xterm.c (XTflash): Get the current time closer to when it's used. * src/makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
