(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
* Fix auto-save and locking for indirect buffers.Chong Yidong2012-09-221-2/+6
| | | | | | | | * lisp/simple.el (undo): Handle indirect buffers. * buffer.c (Fset_buffer_modified_p): Handle indirect buffers. Fixes: debbugs:8207
* 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.

(mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking since special buffers aren't marked here any more. (allocate_buffer): Chain new buffer with all_buffers here... * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and not here. (Vbuffer_defaults, Vbuffer_local_symbols): Remove. (syms_of_buffer): Remove staticpro of the above. (init_buffer_once): Set names for buffer_defaults and buffer_local_symbols.
* Simplify redefinition of 'abort' (Bug#12316).Paul Eggert2012-09-041-6/+6
| | | | | | | | | | | | | | | | | | | | | | 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.
* Fix minor problems found by static checking.Paul Eggert2012-09-031-0/+1
| | | | | | | | * buffer.c (Fdelete_all_overlays): Return nil. * doc.c (Fsubstitute_command_keys): * regex.c (WEAK_ALIAS): * xdisp.c (redisplay_internal): Move initialization down, to pacify GCC 4.7.1 -Wjump-misses-init.
* New macro with-temp-buffer-window and related fixes.Martin Rudalics2012-09-031-0/+20

* Do not allow to set major mode for a dead buffer.Dmitry Antipov2012-08-281-4/+4
| | | | | | | * buffer.c (Fset_buffer_major_mode): Signal an error if the buffer is dead. (Fother_buffer, other_buffer_safely): Remove redundant nested declaration.

(mmap_initialized_p): * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int. * buffer.h, lisp.h: Adjust prototypes to match above changes.
* Inline getter and setter functions for per-buffer values.Dmitry Antipov2012-08-201-5/+5
| | | | | | | * 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.
