STINNER Victor <vstin...@redhat.com> added the comment:
Maybe we need to expose an object in the os module to list which parameters are
supported. setsid is not argument, but scheduler is another argument. There is
also a discussion to add another argument to os.posix_spawn() to specify the
working directly: it's not possible on all platforms neither.
Currently, there are os.supports_* constants like os.supports_dir_fd (set of
function names). But I would prefer to have an object just for posix_spawn.
Maybe:
os.supported_posix_spawn_args = ('file_actions', setpgroup', 'resetids',
'setsid', 'setsigmark', 'setsigdef', 'scheduler')
The value would depend depending on the platform.
