I'm quite new to Gevent/Greenlet and have gone through the tutorials. I would like to run a bot for each registered team.
for bot in self.bots:
events.append(gevent.spawn(bot.start))
gevent.joinall(events)
The interesting part is that if I don't use a while true
loop, I get the bot_id
of both bots shown in the console.
def start(self):
while True:
for reply in self.slack_client.rtm_read():
self.input(reply)
time.sleep(0.1)
logger.info("Log:{0}".format(self.bot_id))
But as soon as I use a endless loop, I can only see one bot's id being displayed. It seems as if the other task is waiting for this one to finish, which makes no sense. I thought that gevent.joinall
would run both in parallel.
any advice on this please?
UPDATE
For the record, I had to add gevent.sleep(0.1)
on the last line of while loop to make this work.
From the Gevent introduction:
Only one greenlet is ever running at any given time.
Basically I think that what you are looking for is parallelism not asynchronous operations. Maybe a better fit would be to use the multiprocessing module.
