Zac Medico <zmed...@gentoo.org> added the comment:
I'm not sure about possible use cases that might conflict with this approach,
but using a separate event loop for each pid seems very reasonable to me, as
follows:
_default_policy = asyncio.get_event_loop_policy()
_pid_loop = {}
class MultiprocessingPolicy(asyncio.AbstractEventLoopPolicy):
def get_event_loop(self):
pid = os.getpid()
loop = _pid_loop.get(pid)
if loop is None:
loop = self.new_event_loop()
_pid_loop[pid] = loop
return loop
def new_event_loop(self):
return _default_policy.new_event_loop()
asyncio.set_event_loop_policy(MultiprocessingPolicy())
