      Fix obscure porting bug with varargs functions. · 1396ac86
      Paul Eggert authored
      The code assumed that int is treated like ptrdiff_t in a vararg
      function, which is not a portable assumption.  There was a similar
      -- though these days less likely -- porting problem with various
      assumptions that pointers of different types all smell the same as
      far as vararg functions is conserved.  To make this problem less
      likely in the future, redo the API to use varargs functions.
      * alloc.c (make_save_value): Remove this vararg function.
      All uses changed to ...
      (make_save_int_int_int, make_save_obj_obj_obj_obj)
      (make_save_ptr_int, make_save_funcptr_ptr_obj, make_save_memory):
      New functions.
      (make_save_ptr): Rename from make_save_pointer, for consistency with
      the above.  Define only on platforms that need it.  All uses changed.

      This makes the code easier to read and the executable a bit smaller.
      Do not replace all calls to Fcons that happen to create lists,
      just calls that are intended to create lists.  For example, when
      creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
      rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).

      Use functions, not macros, for XINT etc. · 84575e67
      Paul Eggert authored
      In lisp.h, prefer functions to function-like macros, and
      constants to object-like macros, when either will do.  This:
       . simplifies use, as there's no more need to worry about
         arguments' side effects being evaluated multiple times.
       . makes the code easier to debug on some platforms.
      However, when using gcc -O0, keep using function-like macros
      for a few critical operations, for performance reasons.
      This sort of thing isn't needed with gcc -Og, but -Og
      is a GCC 4.8 feature and isn't widely-enough available yet.
      Also, move functions from lisp.h to individual modules when possible.

      combination) or buffer to display (for the leaf window).  Using that,
      a lof of operations to traverse and/or change window hierarchies may
      be simplified.  New member horizontal is used to distinguish between
      horizontal and vertical combinations of internal windows.

      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.

      Port better to POSIX hosts lacking _setjmp. · 0328b6de
      Paul Eggert authored
      * 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.

      Simplify redefinition of 'abort' (Bug#12316). · 1088b922
      Paul Eggert authored
      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.

      * nt/inc/ms-w32.h (w32_abort) [HAVE_NTGUI]: Remove.

      * src/lisp.h (emacs_abort): New decl.  All calls from Emacs code to
      'abort' changed to use 'emacs_abort'.
