* s/irix4-0.h: Get rid of our fake definitions for setpgrp and
getpgrp.
* callproc.c (Fcall_process): Go ahead and use the USG calling
convention for setpgrp.
* ymakefile (pre-crt0.o): Add rule for this. Perhaps it will help
separate-source-directory compilation.
* emacs.c (shut_down_emacs): Some USG systems #define
EMACS_HAVE_TTY_PGRP; call getpgrp as appropriate for such systems.
* sysdep.c (sys_suspend): Call getpgrp as appropriate for USG and
non-USG.
* process.c [IRIX] (create_process): Don't put child in process
group zero before opening the tty; Irix is like USG in this
regard.
call setpgrp with arguments, even if USG is #defined.
* process.c [IRIX] (create_process): Don't call setpgrp before
opening the pty. Call it after doing the TIOCNOTTY ioctl.
* s/template.h: Mention that you should #define HAVE_TERMIO or
HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
tcsetpgrp to *pgid; it's just a status value.
* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
systems using XFree386, and perhaps is inappropriate in general.
* m/intel386.h: #undefine the integer size macros, since the Linux
<values.h> file #defines them itself.
* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
fails, fall back on ULIMIT_BREAK_VALUE.
* process.c: Linux needs the WAITTYPE, etc. definitions.
* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
no need to use SYSV names.
* s/linux.h: New file.
equivalent of /dev/null, and the suffixes used by executable
files. This is simple, and helps people porting Emacs to other
operating systems.
* process.h (NULL_DEVICE): Give this a default value.
* process.c (Fstart_process): Pass EXEC_SUFFIXES to openp.
(Fprocess_send_eof): Use NULL_DEVICE instead of "/dev/null".
* callproc.c (Fcall_process): Pass EXEC_SUFFIXES to openp.
Use NULL_DEVICE instead of "/dev/null".
floating-point as well as integer arguments. subr.el defines the
former as an alias for the latter.
* data.c (Fnumber_to_string): Renamed from Fint_to_string.
(wrong_type_argument): Adjust caller.
(syms_of_data): Adjust defsubr.
* fns.c (concat): Adjust caller.
* lisp.h (Fnumber_to_string): Adjust extern declaration.
* mocklisp.c (Finsert_string): Adjust caller.
* process.c (status_message): Adjust caller.
control characters to processes, don't try to return Qnil; just
return.
* process.c [! subprocesses] (wait_reading_process_input):
Remember to re-enable polling for input.
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.
