Refactor extensions to eliminate ExtensionMiddleware and LazySerializationMiddleware

Registered by Kevin L. Mitchell on 2012-01-11

Refactor extensions such that we can dispose of ExtensionMiddleware and LazySerializationMiddleware. Extensions will be called directly from within the nova.api.openstack.wsgi.Resource class, instead of in a separate middleware. Doing this will also allow us to eliminate the LazySerializationMiddleware.

Most of this is now addressed. Rick Harris is working on the last plugin which uses the deprecated interfaces—disk_config.py—and once that goes in, I'll submit a patch which removes the deprecated classes, including middleware… —Vek
