On last midcycle meetup was decided to make snapshots optional feature. Features: - Add new boolean capability 'snapshot_support' to base share driver so every existing share driver will inherit it. Make value of it be calculated from the fact of redefinition of three main driver methods for snapshots 'create_snapshot', 'delete_snapshot' and 'create_share_from_snapshot'. - Set extra spec 'snapshot_support' with share type creation by default to 'True' - Restrict deletion of extra spec 'snapshot_support' that is expected to exist - Allow to redefine new extra spec 'snapshot_support' - Restrict API 'snapshot create' for share created with share type that has extra spec 'snapshot_support' equal to 'False'. - Add migration where new extra spec 'snapshot_support' is added to all share types that do not have it yet. Partially implements bp snapshots-optional Change-Id: I069d9e911c7d7a708fa518b38ed10572a45e5f42 |
