the sigchld handler clear *input_available_clear_time.
(wait_reading_process_input): Check for process activity after
setting the timeout and calling set_waiting_for_input.
(sigchld_handler): If the process which has exited is one we care
about, clear *input_available_clear_time.
* process.c (process_send_signal): Use TERMIOS functions in
preference to BSD ioctls. Some systems attempt to provide the BSD
functions for backward compatibility, and get it wrong.
garbaged whenever it goes from invisible to visible.
* dispextern.h (frame_garbaged): Move extern declaration from here...
* frame.h (frame_garbaged): ... to here. The FRAME_SAMPLE_VISIBILITY
macro uses it now, and this seems to be just as modular. Make a
new page, just for this and message_buf_print.
(struct frame): Doc fix for the `visible' field.
* process.c: #include "frame.h" instead of "dispextern.h"; the
only thing we care about from it is the frame_garbaged
declaration.
* ymakefile: Note dependency change.
for subprocesses when the buffer's default-directory is a handled
name.
* fileio.c (Funhandled_file_name_directory): New function.
(Qunhandled_file_name_directory): New file-name-handler operation.
(syms_of_fileio): Defsubr Sunhandled_file_name_directory, and
initialize and staticpro Qunhandled_file_name_directory.
* callproc.c (Fcall_process): Call Funhandled_file_name_directory
on the buffer's default directory. Do it earlier in the function
so there's less to GCPRO.
* process.c (create_process): Don't check the validity of the
buffer's default directory here...
(Fstart_process): Instead, do it here; if we call
Funhandled_file_name_directory here, there's less GCPROing to do.
Added VMS changes from Roland Roberts.
* process.c (read_process_output): Save, widen, insert the process
output, and then restore the restriction if inserting text outside
the visible region.
* process.c (Fstart_process): Establish an unwind-protect to
remove PROC from the process list if an error occurs while
starting it.
(start_process_unwind): New function to help with that.
(create_process): There's no need to explicitly call
remove_process if the fork fails; the record_unwind_protect in
Fstart_process will take care of it.
* process.c (wait_reading_process_input): Test the C preprocessor
symbol "ultrix", not "__ultrix__" to see if we should ignore
ENOMEM errors from select.
* process.c (process_send_signal): On systems which have both
the TIOCGETC and TCGETA ioctls, just use the former.
* s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
* process.c (process_send_signal): Put all the code for sending
signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS. Decide
whether to use the Berkeley-style or SYSV-style ioctls by seeing
which ioctl commands are #defined.
* process.c (process_send_signal): Doc fix.
Lisp_Object at the top of the file.
(decode_status): Don't untag XCONS (tem)->cdr before storing it in
tem; tem is a Lisp_Object, too.
(process_send_signal): Declare this to be static void. Don't
return Qnil; nobody cares.
(sigchld_handler): Use XFASTINT to manipulate p->infd.
* process.c (pty_process): Variable deleted; it's no longer used.
(syms_of_process): Don't initialize it.
(create_process): #if 0 out the code which sets the child's
handler for SIGCHLD to sigchld; the code which gives sigchld its
value has been diked out under these CPP symbols, so this should
be diked out too.
system doesn't have that facility.
* process.c: [USG5] Don't include <fcntl.h>.
[USG] Don't bother including termios, termio, or fcntl; systerm.h
takes care of all that.
Remove the "mis;tak-+;;" line from the code; apparently this
section of code does get used.
* process.c (wait_reading_process_input): Put comments around
text following #endif.
