Michelle Caisse commented on JDO-460:
-------------------------------------
The spec (see
https://issues.apache.org/jira/secure/attachment/12349043/stateTransitionsUpdates.htm)
says:
Given operation detachCopy with active Optimistic transaction and initial state
hollow, state transitions to P-nontrans.
Given operation detachCopy with active Datastore transaction and initial state
hollow, state transitions to P-clean.
Given operation detachCopy with active transaction and initial state
P-nontrans: If a field of a persistent-nontransactional instance needs to be
read for detachCopy with an active transaction, the instance will transition to
persistent-clean if a datastore transaction is active; otherwise the instance
will not change state.
I believe that this is intended to mean that the transition of hollow and
P-nontrans instances to a detachCopy operation are identical. If this is
correct, then the state transitions table in the StateTransitions.java is wrong
in that the cell for operation detachCopy with active datastore transaction,
initial state PERSISTENT_NONTRANSACTIONAL should read PERSISTENT-CLEAN rather
than UNCHANGED. The outcome of the case that is currently failing is unchanged
and still needs to be fixed, but the impossible constraint that the outcome
should be different for hollow and persistent nontransactional instances would
be lifted with this change to the test.
