delete_port() calls to disassociate_floatingips() while in transaction. The latter method sends RPC notification which may result in eventlet yield. If yield switches a thread to another one that tries to access the same floating IP object in db as disassociate_floatingips() method does, we're locked and get db timeout. We should avoid calling to notifier while under transaction. To achieve this, I introduce a do_notify argument that controls whether notification is done by disassociate_floatingips() itself or delegated to caller. Callers that call to disassociate_floatingips() from under transactions should handle notifications on their own. For this, disassociate_floatingips() returns a set of routers that require notification. Updated drivers to reflect new behaviour. Added unit test.
