Kevin Wolf 6a8c0b5102 qapi: Add feature flags to struct types ... Sometimes, the behaviour of QEMU changes without a change in the QMP syntax (usually by allowing values or operations that previously resulted in an error). QMP clients may still need to know whether they can rely on the changed behavior. Let's add feature flags to the QAPI schema language, so that we can make such changes visible with schema introspection. An example for a schema definition using feature flags looks like this: { 'struct': 'TestType', 'data': { 'number': 'int' }, 'features': [ 'allow-negative-numbers' ] } Introspection information then looks like this: { "name": "TestType", "meta-type": "object", "members": [ { "name": "number", "type": "int" } ], "features": [ "allow-negative-numbers" ] } This patch implements feature flags only for struct types. We'll implement them more widely as needed.
