Kombu tests occasionally hang

[Aaron Lee]

Occasionally the tests will hang while running test_iterconsume_errors_will_reconnect in test_kombu. I've only seen this issue on OSX or VMs running under OSX, so I consider this minor for now.

[Bernhard M. Wiedemann (ubuntubmw)]

I found that this always happens with kombu>=1.2.1
9979ea0ac9cc4fd1c6339140b264e781e923d2be is first bad commit on git://github.com/ask/kombu.git

To reproduce I did
python nova/testing/runner.py -w . nova/tests/rpc/test_kombu.py:RpcKombuTestCase.test_iterconsume_errors_will_reconnect

From the mailing list, it looked like Ask was going to look at this. I'm going to mark this as incomplete until we know whether it's a problem in nova or kombu.

I have the same problem -- Using ubuntu precise.

[Bernhard M. Wiedemann (ubuntubmw)]

got this via mail from Ask:

I think I understand why this is failing now, and have decided
to remove the auto_delete support from virtual transports,
as I believe that it is prone to race conditions. The only
way this could be implemented properly is if it is able
to know how many actual consumers there are of the queue
before it can delete it.

I will be releasing a new kombu bugfix release shortly.

[Ask Solem (asksol)]

The fix was released with Kombu 2.1.8

[OpenStack Infra (hudson-openstack)]

Fix proposed to branch: master

Looks like you're not working on that anymore. Please set back to InProgress and reassign to you if you're working on proposing a change for merging.

nova is already unpinned from 1.0.4

dims@dims-laptop:~/openstack/nova$ grep -e anyjson -e kombu tools/pip-requires
anyjson>=0.2.4
kombu>=1.0.4

oslo has a pending review to switch to the same

https://review.openstack.org/#/c/18942/

So i don't think this bug is valid any more
