Duong updated RATIS-2094:
-------------------------
Description:
was:
In RATIS-2020, we've changed access to LogEntry in TransactionContext to either
via reference count (refer to the original zero-copy message) or copying (for
backward compatibility).
However, the same thing is not done for log entry derived data (data extracted
from the original log entry or original message) like "stateMachineLogEntry" or
even "getStateMachineContext". This allows StateMachine to use zero-copy data
without obtaining a reference count or copying to decouple, hence corruption
possibility.
We should deprecate the getStateMachineLogEntry and getStateMachineContext and
provide access via the reference counter instead.
> TransactionContext's stateMachineLogEntry and stateMachineContext may cause
> corruption
