We definitely shouldn't be running all the IPv6 tests. But I also think the assumption that the failure rate is low is not a valid reason to keep a test. Unreliable tests that don't have anyone looking into them should be deleted. They are providing negative value. Because people just recheck past them even if their code made the race worse. So any legitimate issues they are exposing are being ignored. If the neutron PTL wants tests pulled, we should just do it. -Sean -- Sean Dague http://dague.net __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
