New submission from Matthew Tanous <mtanou...@gmail.com>:
Allowing posix_spawn file_actions to default to None works, but explicitly
setting it throws a TypeError:
Python 3.8.0a3 (v3.8.0a3:9a448855b5, Mar 25 2019, 17:05:20)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> os.posix_spawnp('whoami', ['whoami'], os.environ, file_actions=None)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: file_actions must be a sequence or None
This required me to default to an empty sequence to complete it:
>>> os.posix_spawnp('whoami', ['whoami'], os.environ, file_actions=[])
