Craig L Russell updated JDO-589:
--------------------------------
Summary: Allow makePersistent and deletePersistent outside a transaction
(was: Allow makePersistent outside a transaction)
> Allow makePersistent and deletePersistent outside a transaction
> ---------------------------------------------------------------
>
> Key: JDO-589
> URL: https://issues.apache.org/jira/browse/JDO-589
> Project: JDO
> Issue Type: New Feature
> Components: api, specification, tck
> Affects Versions: JDO 2 maintenance release 1 (2.1)
> Reporter: Craig L Russell
> Fix For: JDO 3.2
>
>
> JPA allows users to call makePersistent outside a transaction, and then when
> beginning and committing a transaction, the instances are made persistent.
> This is similar to nontransactional dirty in which the managed instances can
> be modified outside a transaction and then the changes committed within a
> transaction.
> From the JPA spec, "When an EntityManager with an extended persistence
> context is used, the persist, remove, merge, and refresh operations may be
> called regardless of whether a transaction is active. The effects of these
> operations will be committed to the database when the extended persistence
> context is enlisted in a transaction and the transaction commits."
> This behavior should not be the default behavior (for backward compatibility
> reasons if not the principle of least surprise) so it should be under control
> of a PersistenceManager and PersistenceManagerFactory flag, perhaps
> NontransactionalNew.
