Title:
Version change in ObjectField does not work with back-levelling
Status in OpenStack Compute (nova):
In Progress
Status in oslo.versionedobjects:
New
Bug description:
When a NovaObject primitive is deserialized the object version is
checked and an IncompatibleObjectVersion exception is raised if the
serialized primitive is labelled with a version that is not known
locally. The exception indicates what version is known locally, and
the deserialization attempts to backport the primitive to the local
version.
If a NovaObject A has an ObjectField b containing NovaObject B and it
is B that has the incompatible version, the version number in the
exception will be the the locally supported version for B. The
desrialization will then attempt to backport the primitive of object A
to the locally supported version number for object B.
