Return Deleted Instance on Show

Registered by Andrew Melton

Currently the Nova API returns a 404: ItemNotFound response when a show is made on a deleted instance. As the data about an instance is soft-deleted, it may still be in the database and available to return to the user. The modified show call would be gated by a policy and would only show deleted instances if the users role allowed it. The call would still return 404 when the users role does not allow showing of deleted instances.

Whiteboard

In grizzly we added 'db-archiving' such that soft-deleted rows can be archived elsewhere. I don't think we should add an API for something unless we intend for it to always work. We should discuss this on the openstack-dev list. --russellb

Gerrit topic: https://review.openstack.org/#q,topic:bp/show-deleted-instances,n,z

    Add policy to allow showing of deleted instance.

As suggested, I attempted to start a discussion on openstack-dev, but I have not received any input from any Nova devs. Please find the thread here: http://lists.openstack.org/pipermail/openstack-dev/2013-April/008219.htmlIn grizzly we added 'db-archiving' such that soft-deleted rows can be archived elsewhere.
