unittest will keep each test case around after completion pinning any objects references by attributes on the test case. This can bloat the memory used during a full test suite run to the point where the test suite will require much more memory than running all of the services does. On systems witout lots of memory, test suite failures will occur as test cases cannot fork to execute programs. Clearing out __dict__ of any attributes that don't start with a _ (since some are needed by unittest itself) reduces memory significantly. This does require the super class tearDown to be called last in some cases however. Change-Id: I0e660b6c2a77c5613c5a523ba0a64c3d7f6dd128
The Choose Your Own Adventure README for Nova
You have come across a cloud computing fabric controller. It has identified itself as "Nova." It is apparent that it maintains compatibility with the popular Amazon EC2 and S3 APIs.
To monitor it from a distance: follow @openstack on twitter.
To tame it for use in your own cloud: read http://docs.openstack.org
To study its anatomy: read http://nova.openstack.org
To dissect it in detail: visit http://github.com/openstack/nova
To taunt it with its weaknesses: use http://bugs.launchpad.net/nova
To watch it: http://jenkins.openstack.org
To hack at it: read HACKING
To cry over its pylint problems: http://jenkins.openstack.org/job/nova-pylint/violations
