Public bug reported: I have seen the fullstack tests sometimes fail, complaining that the namespace doesn't exist. An example is here:
http://logs.openstack.org/79/604179/1/check/neutron-fullstack- python36/9b41cd5/logs/testr_results.html.gz End of stack trace for reference: File "/opt/stack/new/neutron/neutron/tests/fullstack/resources/process.py", line 354, in clean_dhcp_namespaces ip_lib.delete_network_namespace(namespace) File "/opt/stack/new/neutron/neutron/agent/linux/ip_lib.py", line 1103, in delete_network_namespace privileged.remove_netns(namespace, **kwargs) File "/opt/stack/new/neutron/.tox/dsvm-fullstack-python35/lib/python3.5/site-packages/oslo_privsep/priv_context.py", line 207, in _wrap return self.channel.remote_call(name, args, kwargs) File "/opt/stack/new/neutron/.tox/dsvm-fullstack-python35/lib/python3.5/site-packages/oslo_privsep/daemon.py", line 202, in remote_call raise exc_type(*result[2]) FileNotFoundError: [Errno 2] No such file or directory While some callers check for RuntimeError, none check for this OSError errno.ENOENT case. In this case, I don't believe we should be returning an error at all, since an asynchronous event could have deleted the namespace, and since it's no longer there we are in the desired state. This will help with some of the recent issues we've had getting code merged. ** Affects: neutron Importance: High Assignee: Brian Haley (brian-haley) Status: In Progress -- You received this bug notification because you are a member of Yahoo!
