      Avoid encoding file names run through dostounix_filename on MS-Windows. · e7ac588e

      Drop async_visible and async_iconified fields of struct frame. · edfa7fa0
      Dmitry Antipov authored
      This is possible because async input is gone; for details, see
      http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
      * frame.h (struct frame): Remove async_visible and async_iconified
      members, convert garbaged to unsigned bitfield.  Adjust comments.

      (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
      * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
      Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
      FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
      * w32term.c: Ditto.
      (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
      properly.  Likewise for obscured.
      * xterm.c: Ditto.

      properly.

      Simplify and avoid signal-handling races. · 4d7e6e51
      Paul Eggert authored
      * 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.
