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

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

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.

(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

(die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead of doing the work ourselves. * src/emacs.c (fatal_error_signal): Let fatal_error_backtrace do most of the work. (fatal_error_backtrace): New function, taken from the guts of the old fatal_error_signal, but with a new option to output a backtrace. (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful info about the signal than just its number. * src/lisp.h (fatal_error_backtrace, emacs_backtrace): New decls. * src/sysdep.c: Include <execinfo.h> (emacs_backtrace): New function, taken partly from the previous code of the 'die' function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
