Middleware or core features may need to store metadata against accounts or containers. This patch adds a generic mechanism for system metadata to be persisted in backend databases, without polluting the user metadata namespace, by using the reserved header namespace x-<server_type>-sysmeta-*. Modifications are firstly that backend servers persist system metadata headers alongside user metadata and other system state. For accounts and containers, system metadata in PUT and POST requests is treated in a similar way to user metadata. System metadata is not yet supported for object requests. Secondly, changes in the proxy controllers ensure that headers in the system metadata namespace will pass through in requests to backend servers. Thirdly, system metadata returned from backend servers in GET or HEAD responses is added to the cached info dict, which middleware can access. Finally, a gatekeeper middleware module is provided which filters all system metadata headers from requests and responses by removing headers with names starting x-account-sysmeta-, x-container-sysmeta-. The gatekeeper also removes headers starting x-object-sysmeta- in anticipation of future support for system metadata being set for objects. This prevents clients from writing or reading system metadata. The required_filters list in swift/proxy/server.py is modified to include the gatekeeper middleware so that if the gatekeeper has not been configured in the pipeline then it will be automatically inserted close to the start of the pipeline. blueprint cluster-federation Change-Id: I80b8b14243cc59505f8c584920f8f527646b5f45
