* Fix bug #12805 with compilation error in the cygw32 build.Eli Zaretskii2012-11-053-1/+18
| | | | | | | src/makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h. src/w32fns.c Include unistd.h, to avoid compiler warnings on Cygwin. (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use file descriptor 2 for standard error.
* * process.c (wait_reading_process_output): Revert previous change.Chong Yidong2012-11-052-7/+13

* Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid.Paul Eggert2012-11-0410-86/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | This removes code that has been obsolete since around 1990. * admin/CPP-DEFINES (HAVE_SETPGID, HAVE_SETSID, SETPGRP_RELEASES_CTTY): Remove; obsolete. * configure.ac (setpgid, setsid): Assume their existence. (AC_FUNC_GETPGRP, SETPGRP_RELEASES_CTTY): Remove; obsolete. * src/callproc.c (Fcall_process): * src/emacs.c (main): * src/process.c (create_process): * src/term.c (dissociate_if_controlling_tty): Assume setsid exists. * src/callproc.c (child_setup): Assume setpgid exists and behaves as per POSIX.1-1988 or later. * src/conf_post.h (setpgid) [!HAVE_SETPGID]: Remove. * src/emacs.c (shut_down_emacs): * src/sysdep.c (sys_suspend, init_foreground_group): Assume getpgrp behaves as per POSIX.1-1998 or later. * src/msdos.c (setpgrp): Remove. (tcgetpgrp, setpgid, setsid): New functions. * src/systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp. * src/term.c (no_controlling_tty): Remove; unused. * src/w32proc.c (setpgrp): Remove. (setsid, tcgetpgrp): New functions. Fixes: debbugs:12800
* Simplify by assuming __fpending.Paul Eggert2012-11-042-4/+9
| | | | | | | | | | | Now that Emacs is using the gnulib fpending module, there's no need for Emacs to have a separate implementation. * configure.ac (stdio_ext.h, __fpending): Remove now-duplicate checks. (PENDING_OUTPUT_COUNT, DISPNEW_NEEDS_STDIO_EXT): Remove. * admin/CPP-DEFINES (PENDING_OUTPUT_COUNT): Remove. * src/dispnew.c: Include <fpending.h>, not <stdio_ext.h>. (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT. Do not assume that __fpending's result fits in int.
* Remove EMACS_OUTQSIZE+sleep hack.Paul Eggert2012-11-043-26/+9
| | | | | | | | | * dispnew.c (update_frame_1): Remove hack for terminals slower than 2400 bps, which throttled Emacs by having it sleep. This code hasn't worked since at least 2007, when the multi-tty stuff was added, and anyway those old terminals are long dead. * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even without the dispnew.c change, as dispnew.c doesn't include systty.h.
* Fix data-loss with --version.Paul Eggert2012-11-042-3/+12
| | | | | | | | | | * emacs.c (close_output_streams): Use strerror, not emacs_strerror, as we can't assume that emacs_strerror is initialized, and strerror is good enough here. (main): Invoke atexit earlier, to catch earlier instances of sending data to stdout and exiting, e.g., "emacs --version >/dev/full". Fixes: debbugs:9574
* * nsterm.m: Add NSClearLineFunctionKey and keypad keys.Michael Marchionna2012-11-042-3/+28
| | | | | | (keyDown): Remap keypad keys to X11 virtual key codes. Fixes: debbugs:8680

(msdos_fatal_signal): New function. (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to its argument list. src/conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline" for GCC versions before 4. (emacs_raise): Define to call msdos_fatal_signal. lisp/term/pc-win.el: Don't load term/internal from here. lisp/loadup.el: Load term/internal from here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * admin/merge-gnulib (GNULIB_MODULES): Add close-stream. * lib/close-stream.c, lib/close-stream.h, lib/fpending.c * lib/fpending.h, m4/close-stream.m4, m4/fpending.m4: New files, from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * src/emacs.c: Include <close-stream.h>. (close_output_streams): New function. (main): Pass it to atexit, so that Emacs closes stdout and stderr and handles errors appropriately. (Fkill_emacs): Don't worry about flushing, as close_output_stream does that now. Fixes: debbugs:9574
* | Fix a race condition that causes Emacs to mess up glib.Paul Eggert2012-11-033-95/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The symptom is a diagnostic "GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned." The diagnostic is partly wrong, as the SIGCHLD action is not set to SIG_IGN. The real bug is a race condition between Emacs and glib: Emacs does a waitpid (-1, ...) and reaps glib's subprocess by mistake, so that glib can't find it. Work around the bug by invoking waitpid only on subprocesses that Emacs itself creates. * process.c (create_process, record_child_status_change): Don't use special value -1 in pid field, as the caller now must know the pid rather than having the callee infer it. The inference was sometimes incorrect anyway, due to another race. (create_process): Set new 'alive' member if child is created. (process_status_retrieved): New function. (record_child_status_change): Use it. Accept negative 1st argument, which means to wait for the processes that Emacs already knows about. Move special-case code for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of processes that have already been waited for, by testing and clearing new 'alive' member. (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change now does this internally. (handle_child_signal): Let record_child_status_change do all the work, since we do not want to reap all exited child processes, only the child processes that Emacs itself created. * process.h (Lisp_Process): New boolean member 'alive'. Fixes: debbugs:8855
* | Omit duplicate definitions no longer needed with gcc -g3.Paul Eggert2012-11-032-22/+15
| | | | | | | | | | | | | | | | * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG) (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM): Define only as macros. There's no longer any need to also define these symbols as enums or as constants, since we now assume gcc -g3 when debugging.

* | Remove pad from struct input_event.Dmitry Antipov2012-11-024-28/+24
|/ | | | | | | | | | | * termhooks.h (struct input_event): Remove padding field. Adjust comment. * keyboard.c (event_to_kboard): Simplify because frame_or_window member is never cons for a long time. Adjust comment. (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment. * xterm.c (handle_one_xevent): Do not initialize frame_or_window field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
* Fix MS-Windows build broken by fixing bug #12776 on Posix platforms.Eli Zaretskii2012-11-012-0/+16

(Fcall_process): Don't invoke both setsid and setpgid; the former is enough, if it exists. * callproc.c (Fcall_process, child_setup): * process.c (create_process): Use setpgid. * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes for the real thing. * dispnew.c (init_display): Initialize the foreground group if we are running a tty display. * emacs.c (main): Do not worry about setpgrp; init_display does it now. * lisp.h (init_foreground_group): New decl. * sysdep.c (inherited_pgroup): New static var.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid overflow in w32 implementation of interval timers. When possible, for ITIMER_PROF count only times the main thread actually executes. src/w32proc.c <struct itimer_data>: 'expire' and 'reload' are now ULONGLONG types. Likewise for all the other data which was previously clock_t. (GetThreadTimes_Proc): New typedef. (w32_get_timer_time): New function, returns a suitable time value for the timer. (timer_loop): Enter critical section when accessing ULONGLONG values of the itimer_data struct, as these accesses are no longer atomic. Call 'w32_get_timer_time' instead of 'clock'. (init_timers): Initialize s_pfn_Get_Thread_Times. (start_timer_thread): Don't assign itimer->caller_thread here. (getitimer): Assign itimer->caller_thread here. (setitimer): Always call getitimer to get the value of ticks_now.
