nova.cmd.rpc_zmq_receiver:main is missing

[yong sheng gong]

I am trying to run devstack with zeromq, but the zeromq failed.

al/bin/nova-rpc-zmq-receiver & echo $! >/opt/stack/status/stack/zeromq.pid; fg || echo "zeromq failed to start" | tee "/opt/stack/status/stack/zeromq.failure"
[1] 25102
cd /opt/stack/nova && /usr/local/bin/nova-rpc-zmq-receiver
Traceback (most recent call last):
  File "/usr/local/bin/nova-rpc-zmq-receiver", line 6, in <module>
    from nova.cmd.rpc_zmq_receiver import main
ImportError: No module named rpc_zmq_receiver
zeromq failed to start

I found at https://github.com/openstack/nova/blob/master/setup.cfg:
nova-rpc-zmq-receiver = nova.cmd.rpc_zmq_receiver:main

but at https://github.com/openstack/nova/tree/master/nova/cmd:
we have no rpc_zmq_receiver module at all.

nova.cmd.rpc_zmq_receiver went away in https://review.openstack.org/#/c/39929/, the switch to oslo.messaging

[Doug Hellmann (doug-hellmann)]

The project-specific receiver command has been replaced with oslo-messaging-zmq-receiver. I think you will need to update devstack to call that program instead, but I'm not 100% sure of how the zmq stuff actually uses that command.

Adding devstack since that's what needs to be updated

    Remove zmq-receiver from setup.cfg

    In commit 1a91aac we removed the zmq-receiver script (in favor of
    oslo-messaging-zmq-receiver) but forgot to remove the entry from
    setup.cfg.

    Use oslo-messaging-zmq-receiver to start zeromq receiver

    The project-specific receiver command nova-rpc-zmq-receiver
    has been replaced with oslo-messaging-zmq-receiver.

    We need to update devstack code accordingly.
