Hello all,
When I use redis with gevent and uwsgi, some of my processes seem to hang.
I’ve isolated the error I’m getting in the code snippet below.
When I use the following command ( uwsgi --gevent 100 --socket 0.0.0.0:8000
--protocol=http -w testapp -p 4 ) to have uwsgi run 4 workers I expected
'done' to be print 4 time to standard output, but it doesn't. If I remove
the monkey patching, things works fine and I get the 'done' to print 4
times. When I use one process, everything works find, but anymore then that
and I would get the hanging problem.
Any help would be appreciated.
from gevent import monkey; monkey.patch_all()import redis, geventfrom
flask import Flask
application = Flask(__name__)
r = redis.StrictRedis(host='localhost', port=6379, db=0)
def setup_cache():
r.set('a', 'b')
print 'done'
@application.route('/')def hello_world():
return 'Hello World!'
gevent.spawn(setup_cache)
if __name__ == "__main__":
application.run()
