[infinispan-issues] [Red Hat JIRA] (ISPN-11614) PersistenceMarshaller should utilise an independent SerializationContext for user types

PersistenceMarshaller should utilise an independent SerializationContext for user types --------------------------------------------------------------------------------------- Key: ISPN-11614 URL: https://issues.redhat.com/browse/ISPN-11614 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 10.1.5.Final, 11.0.0.Dev03 Reporter: Ryan Emerson Assignee: Ryan Emerson Priority: Major Fix For: 12.0.0.CR1 If a user configures a SerializationContextInitializer it is currently registered to the same SerializationContext as the persistent internal types. This means that it is possible for a user to reference internal protobuf message types in their .proto files.  We should introduce the following: # A "user" SerializationContext that is used exclusively for user types configured via xml/service-loader/programmatically: User types are only registered with this context. The global and persistence contexts do not register these types.  If a type does not exist in the global/persistence context, then it's wrapped with a MarshallableUserObject and marshalling is delegated to the user marshaller. Previously this only occurred if a custom marshaller was defined as user types were added to the global/persistence context, but as this is no longer the case all user types are wrapped. # A USER_MARSHALLER created by MarshallerFactory, which if a custom marshaller is not defined creates a ProtoStream based marshaller that consumes the user SerializationContext, if a custom marshaller is defined then that is returned: This logic was previously in the PersistenceMarshallerImpl, but this allows us to inject the marshaller directly into various places in the code. # DelegatingUserMarshaller. A wrapper class to call the start/stop of the configured user marshaller and log the marshaller being used.
