I have found a similar question, ZeroMQ: HWM on PUSH does not
work<http://stackoverflow.com/questions/21133535/zeromq-hwm-on-push-does-not-work>,
but it couldn't solve my problem.
I want to control the number of messages that the push socket queues, but
it doesn't work.
So I want to know how to set the hwm of the push socket. Thanks in advance.
My environment is: libzmq 4.0.4, pyzmq 14.1.0, python 3.3
Here's my code:
server.py
> #!/usr/bin/env python3# -*- coding: utf-8 -*-
> import random
> import zmq
>
> class TestPush(object):
>
> def __init__(self):
> self.ctx = zmq.Context()
>
> random.seed()
>
> def run(self):
> task_snd = self.ctx.socket(zmq.PUSH)
> task_snd.setsockopt(zmq.SNDHWM, 10)
> task_snd.bind('tcp://*:53000')
>
> while True:
> workload = str(random.randint(1, 100))
> task_snd.send(workload.encode('utf-8'))
> print('Send {0}'.format(workload))
>
> if __name__ == '__main__':
> test_push = TestPush()
> test_push.run()
>
> client.py
> #!/usr/bin/env python3# -*- coding: utf-8 -*-
> import timeimport random
> import zmq
>
> class TestPull(object):
>
> def __init__(self):
> self.ctx = zmq.Context()
>
> def run(self):
> task_rcv = self.ctx.socket(zmq.PULL)
> task_rcv.setsockopt(zmq.RCVHWM, 1)
> task_rcv.connect('tcp://localhost:53000')
>
> while True:
> msg = task_rcv.recv()
> print('Receive msg: {0}'.format(msg))
>
> time.sleep(random.randint(2, 3))
>
> if __name__ == '__main__':
> test_pull = TestPull()
> test_pull.run()
>

宠辱不惊，闲看庭前花开花落；去留无意，漫随天边云卷云舒。
