Devstack installation error - Initializing Designate - AttributeError: 'module' object has no attribute 'set_defaults'

recently I've been re-installing Devstack successfully couple of times. Today I got following error:

==> default: 2016-11-10 13:26:02.723 | Initializing Designate
==> default: Traceback (most recent call last):
==> default:   File "/usr/local/bin/designate-manage", line 10, in <module>
==> default:     
==> default: sys.exit(main())
==> default:   File "/opt/stack/designate/designate/cmd/manage.py", line 110, in main
==> default:     utils.read_config('designate', sys.argv)
==> default:   File "/opt/stack/designate/designate/utils.py", line 109, in read_config
==> default:     config.set_defaults()
==> default:   File "/opt/stack/designate/designate/common/config.py", line 21, in set_defaults
==> default:     cors.set_defaults(
==> default: AttributeError: 'module' object has no attribute 'set_defaults'
==> default: Error on exit

The installation was done on in 2 environments:

  1. Vagrant + VirtualBox - "ubuntu/trusty64" image + branch stable/mitaka
  2. VMWare Fusion with Ubuntu 14.04.5 LTS server image + branch stable/mitaka

In each case the same error occurs.

Both todays and every previous (successful) installations have been done with the Designate plugin enabled in local.conf:

# Enable designate
enable_plugin designate https://git.openstack.org/openstack/designate   

# Designate Devstack Config
# =========================
# Enable core Designate services
enable_service designate,designate-central,designate-api,designate-pool-manager,designate-zone-manager,designate-mdns

Looks like some version mismatch between the designate and oslo.middleware Python modules, which came out in recent days (or hours).

Any ideas how to solve that?

For anyone else that stumbles here:

I was getting an error upgrading to ocata because the keystone-wsgi-public script was trying to call cors.set_defaults (and throwing the same error). This cors depdency was provided as part of the python2-oslo-middleware RPM and needed to be yum upgraded by hand for me (soft dependency).

I've experienced the error because of the following commit: https://github.com/openstack/designate/commit/04374fcb53bc5c4d5cfb058907d5b351ed546a38

It was my bad though, because I should declare the stable/mitaka branch for the plugin (more generally - the same branch as the one for Devstack clone), so it should go like follows:

# Enable designate
enable_plugin designate https://git.openstack.org/openstack/designate stable/mitaka

The above solves my problem.
