      Implement cygw32 · 0fda9b75
      Daniel Colascione authored
      Here, we use the generic window-system configuration system we just
      implemented to support the w32 window-system in the mainline build
      under Cygwin.  (Previously, the w32 window system could only be
      compiled as part of the NT-native Emacs build process.)
      
      The changes in this patch need to be applied atomically in order to
      avoid breaking Emacs.  The changes include:
      
        - Changes throughout the Lisp and C code to not assume that
            NT Emacs and the w32 window system are synonymous.
      
        - Wiring up the regular select(2) event loop to Windows messages
      
        - Cleaning up the w32 drag-and-drop receiving code.
      
        - Exposing Cygwin path conversion functions to elisp.
      
        - Unicode file dialog support when compiling for Cygwin.
      
        - Splitting the w32 term lisp initialization code into code
          applicable to any w32 window-system and code specific to
          system-type windows-nt.
      
        - Integrating the old and new w32 code into the build system.

      Remove configure's --without-sync-input option. · 0caaedb1
      Paul Eggert authored
      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>.

      * admin/CPP-DEFINES (BROKEN_SA_RESTART, SA_RESTART): Remove.

      Simplify SIGIO usage. · 4a4bbad2
      Paul Eggert authored
      The code that dealt with SIGIO was crufty and confusing, e.g., it
      played tricks like "#undef SIGIO" but these tricks were not used
      consistently.  Simplify mostly by not #undeffing standard symbols,
      e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
      or not as we please) rather than "defined SIGIO" (standard symbol
      that we probably shouldn't #undef).
      * configure.ac (NO_TERMIO, BROKEN_FIONREAD, BROKEN_SIGAIO)
      (BROKEN_SIGPOLL, BROKEN_SIGPTY): Remove.
      (USABLE_FIONREAD, USABLE_SIGIO): New symbols.  All uses of
      'defined SIGIO' replaced with 'defined USABLE_SIGIO', with no need
      to #undef SIGIO now (which was error-prone).  Likewise, all uses
      of 'defined FIONREAD' replaced with 'defined USABLE_FIONREAD'.
      * src/admin/CPP_DEFINES (BROKEN_SIGAIO, BROKEN_SIGIO, BROKEN_SIGPOLL)
      (BROKEN_SIGPTY, NO_TERMIO): Remove.
      * src/conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
      Modules that need it can include it.
      [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
      * src/dispextern.h (ignore_sigio): New decl.
      * src/emacs.c (shut_down_emacs): Invoke unrequest_sigio
      unconditionally, since it's now a no-op if !USABLE_SIGIO.
      * src/emacs.c (shut_down_emacs):
      * src/keyboard.c (kbd_buffer_store_event_hold):
      Use ignore_sigio rather than invoking 'signal' directly.
      * src/keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
      for FIONREAD.
      (FIONREAD, SIGIO): Do not #undef.
      (tty_read_avail_input): Use #error rather than a syntax error.
      * src/process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
      for I_PIPE, used by SETUP_SLAVE_PTY.
      (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
      * src/sysdep.c (croak): Remove; no longer needed.  This bit of
      temporary code, with Fred N. Fish's comment that it's temporary,
      has been in Emacs since at least 1992!
      (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
      Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
      * src/syssignal.h (croak): Remove decl.
      (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
      * src/systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
      now that we're termios-only.
      (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
      * src/term.c (dissociate_if_controlling_tty): Use #error rather than
      a run-time error.

      Signal-handler cleanup. · 2fe28299
      Paul Eggert authored
      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.

      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.
      * configure.ac (NO_ABRT): Remove.
      * admin/CPP-DEFINES (NO_ABORT): Remove.
      * nt/inc/ms-w32.h (w32_abort) [HAVE_NTGUI]: Remove.

      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.
