cc4edea872 Use posix_spawn if possible.
posix_spawn is less error-prone than vfork + execve, and can make
better use of system-specific enhancements like 'clone' on Linux.  Use
it if we don't need to configure a pseudoterminal.

Backported from commit a60053f836.
Unlike that commit, only define USABLE_POSIX_SPAWN on macOS, because
there posix_spawn is much faster than vfork.

Don't merge to master.

94344d130c Add functions to open a file without quitting.
In some situations, e.g. when the Lisp machinery isn't available, we
can't quit.  Don't check the quit flags in such situations, in case
they contain garbage.

* src/sysdep.c (emacs_open_noquit, emacs_openat_noquit): New variants
of 'emacs_open' and 'emacs_openat' that don't check the quit flags.

* src/emacs.c (main, Fdaemon_initialized):
* src/pdumper.c (pdumper_load):
* src/w32term.c (w32_initialize):
* src/buffer.c (mmap_init):
* src/callproc.c (emacs_spawn): Use them where we can't quit.

4cebd2ded0 Don't unblock SIGCHLD too early.
We first need to register the received process ID so that
'handle_child_signal' checks it.  Otherwise we might never call
'waitpid' for these processes, risking deadlock.

* src/callproc.c (call_process):
* src/process.c (create_process): Don't unblock SIGCHLD before
registering the process ID to wait for.

* src/callproc.c (emacs_spawn): Accept a signal set from the caller.

9076a631fe Port to Solaris 10
* configure.ac: Instead of AC_CHECK_HEADER, use AC_COMPILE_IFELSE
with X11/Intrinsic.h when checking for X11/extensions/Xrender.h.
This suppresses a bogus "report a bug to bug-gnu-emacs" diagnostic
from 'configure' in Solaris 10.
(SETUP_SLAVE_PTY): Adjust to recent renaming of forkin to
std_in in callproc.c.  Needed on Solaris and Unixware.
* lib-src/Makefile.in (LIB_GETRANDOM, LIBS_ETAGS): New vars,
needed because on Solaris 10 the Gnulib tempname module now needs
the -lrt library for clock_gettime.  Throw in the LIB_GETRANDOM
stuff too while we’re at it; from getrandom.m4 it seems to be
needed for MingW.
(LIBS_MOVE, etags_libs): Use them.
* src/callproc.c [SETUP_SLAVE_PTY]: Include sys/stream.h
and sys/stropts.h, for SETUP_SLAVE_PTY’s definiens.
* src/process.c [NEED_BSDTTY]: Don’t include bsdtty.h; hasn’t been
needed in years.
[USG5_4]: Don’t include sys/stream.h or sys/stropts.h; these
directives havbe been moved to callproc.c because the only use of
SETUP_SLAVE_PTY is there now.

527cc64e5d Unbreak the MinGW build broken by recent changes in callproc.c
* src/w32.h (set_process_dir):
* src/w32proc.c (set_process_dir): Change the argument to 'const
char *'.
* src/lisp.h (make_environment_block):
* src/callproc.c (make_environment_block): Now returns 'char **'.
(exec_failed) [DOS_NT]: Remove unused function.
* src/callproc.c (child_setup): NEW_ARGV and ENV are now 'char **'.
Making them 'const' breaks the MinGW build and is not needed for
other platforms.
* src/callproc.c (emacs_spawn): ARGV and ENVP arguments are now
'char *', for the same reason.
* src/process.c (create_process): Adapt to above changes.

bf7041a6f6 Centralize subprocess creation in a single function.
Getting the vfork + execve combination right isn't easy, and the code
was partially duplicated between callproc.c and process.c.  Centralize
the spawn operation in a single function that deals with the nasty
details.  Going forward, we should be able to use posix_spawn from
either libc or Gnulib (or CreateProcessW on Windows) in the non-pty
case.

* src/callproc.c (emacs_spawn): New function to start an asynchronous
subprocess.  Merge code from 'call_process' and 'create_process' into
this function.
(call_process): Use new 'emacs_spawn' function.
(child_setup): Make static, since there are no users outside this
compilation unit left.
(CHILD_SETUP_TYPE): Move from header file, since there are no users
outside this compilation unit left.

* src/process.c (create_process): Use new 'emacs_spawn' function.

95334ee79a Allocate environment block before forking.
While 'child_setup' carefully avoids calls to async-signal-unsafe
functions like 'malloc', it seems simpler and less brittle to use
normal allocation outside the critical section between 'fork' and
'exec'.

* src/callproc.c (make_environment_block): New function to create the
environment block for subprocesses.  Code largely extracted from
'child_setup' and adapted to use 'xmalloc' instead of 'alloca'.
(child_setup): Remove environment block allocation in favor of
passing the environment block as command-line argument.

6d6c55db2c Mark _Noreturn error functions as cold
On my platform this made ‘make compile-always’ 1.3% faster.
Suggested by Alex Gramiak in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00684.html
* configure.ac (nw): Don’t use -Wsuggest-attribute=cold.
* lib-src/make-docfile.c (write_globals):
Mark noreturn functions as cold.

New macro.
(ATTRIBUTE_COLD): New macro.
* src/frame.h (WINDOW_SYSTEM_RETURN): Add ATTRIBUTE_COLD.

9800df69cb Let debugger handle process spawn errors on w32 (Bug#33016)
Since child_setup() is called between block_input()...unblock_input(),
when an error is signaled the Lisp debugger is prevented from
starting.  Therefore, let the callers signal the error instead (which
they already do for non-w32 platforms, just the error message needs an
update).
* src/callproc.c (child_setup) [WINDOWSNT]: Don't call
report_file_error here.
(call_process) [WINDOWNT]:
* src/process.c (create_process) [WINDOWSNT]: Call report_file_errno
here instead, after the unblock_input() call, same as for !WINDOWSNT.
* src/lisp.h (CHILD_SETUP_ERROR_DESC): New preprocessor define.  Flip
the containing ifndef DOS_NT branches so that it's ifdef DOS_NT.
* src/eval.c (when_entered_debugger): Remove.
(syms_of_eval) <internal-when-entered-debugger>: Define it as a Lisp
integer variable instead.
(maybe_call_debugger): Update comment.
* test/src/process-tests.el (make-process-w32-debug-spawn-error):
* test/src/callproc-tests.el (call-process-w32-debug-spawn-error): New
tests.

9cd23a2914 Dissociate controlling tty better on Darwin
* src/process.c (dissociate_controlling_tty): New function.
(create_process): Use it to dissociate controlling tty if setsid
fails, which happens on Darwin after a vfork (Bug#33154).
Do this on all platforms, not just on Darwin, as a similar
problem is plausible elsewhere.
* src/callproc.c (call_process): Use the new function here, too,
for consistency and to avoid duplicate code.
