This patch removes all related DB code from the FWaaS service plugin v2 and creates service driver interfaces that can be used by different backend drivers. The default backend driver still based on the Neutron DB model and agent RPC interface (for l3 and l2 agents) and was moved to 'service_drivers.agents.agents.FwaasAgentDriver'. It inherits from the firewall backend driver DB interface 'service_drivers.driver_api.FwaasDriverDB' to maintain the DB. It is in charge to implement all RPC API and messages. If we need to implement a backend driver which depends on the Neutron DB but not on the agent RPC service, we just have to inherit from the DB interface and if we like to develop a backend driver which not depends on the Neutron DB model, we can inherit from the base driver interface 'service_driver.driver_api.FwaasDriver'. That patch only modifies the service plugin 'firewall_v2', it does not modify the Firewall v1 service plugin. The backend DB driver provides an interface composed to a pre and post commit hooks for each FWaaSv2 API actions which permits to the driver to be warn anytimes. All that commit hooks methods does not do anything by default and the backend driver needs to overide needed hooks. The driver does not needs to implements all of them, Closes-Bug: #1702312 Change-Id: I4ebd24f1b13eb823c4d63452fd37cace5bcf5481 |
