Subject [jira] Created: (JDO-589) Allow makePersistent outside a transaction
Date Wed, 02 Apr 2008 17:39:24 GMT
Allow makePersistent outside a transaction
------------------------------------------

                 Key: JDO-589
                 URL: https://issues.apache.org/jira/browse/JDO-589
             Project: JDO
          Issue Type: New Feature
          Components: api2
    Affects Versions: JDO 2 maintenance release 1
            Reporter: Craig Russell


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.
