zeromq: how to prevent infinite wait?

Question

I just got started with ZMQ. I am designing an app whose workflow is:

1. one of many clients (who have random PULL addresses) PUSH a request to a server at 5555

Answer 1

If you're only waiting for one socket, rather than create a Poller, you can do this:

if work_receiver.poll(1000, zmq.POLLIN):
    print "got message ",work_receiver.recv(zmq.NOBLOCK)
else:
    print "error: message timeout"

You can use this if your timeout changes depending on the situation, instead of setting work_receiver.RCVTIMEO.
