posix_spawn_file_actions_addchdir: New module.
Suggested by Eric Blake in
<https://lists.gnu.org/archive/html/bug-findutils/2018-09/msg00007.html>.
* lib/spawn.in.h (posix_spawn_file_actions_addchdir): New declaration.
* lib/spawn_int.h (struct __spawn_action): Add tag 'spawn_do_chdir' and
union member 'chdir_action'.
* lib/spawn_faction_addchdir.c: New file.
* lib/spawni.c (__spawni): Implement the spawn_do_chdir action.
* lib/spawn_faction_addclose.c: Test REPLACE_POSIX_SPAWN instead of
HAVE_WORKING_POSIX_SPAWN.
* lib/spawn_faction_adddup2.c: Likewise.
* lib/spawn_faction_addopen.c: Likewise.
* m4/posix_spawn_faction_addchdir.m4: New file.
* m4/posix_spawn.m4 (gl_POSIX_SPAWN_BODY): Test whether module
'posix_spawn_file_actions_addchdir' is present and whether
posix_spawn_file_actions_addchdir_np exists. Define REPLACE_POSIX_SPAWN
instead of HAVE_WORKING_POSIX_SPAWN.
* m4/spawn_h.m4 (gl_SPAWN_H): Test whether
posix_spawn_file_actions_addchdir is declared.
(gl_SPAWN_H_DEFAULTS): Initialize
GNULIB_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
REPLACE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR.
* modules/spawn (Makefile.am): Substitute
GNULIB_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR,
REPLACE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR.
* modules/posix_spawn_file_actions_addchdir: New file.
* modules/posix_spawn_file_actions_addclose (Depends-on,
configure.ac): Test also REPLACE_POSIX_SPAWN.
* modules/posix_spawn_file_actions_adddup2 (Depends-on,
configure.ac): Likewise.
* modules/posix_spawn_file_actions_addopen (Depends-on,
configure.ac): Likewise.
* tests/test-spawn-c++.cc (posix_spawn_file_actions_addchdir): Check
signature.
* doc/posix-functions/posix_spawn.texi: Mention the new module.
* doc/posix-functions/posix_spawnp.texi: Likewise.
