[Hibernate-JIRA] Created: (HHH-7239) centralize before/after transaction callbacks in TransactionCoordinator

centralize before/after transaction callbacks in TransactionCoordinator
-----------------------------------------------------------------------
Key: HHH-7239
URL: https://hibernate.onjira.com/browse/HHH-7239
Project: Hibernate ORM
Issue Type: Bug
Components: core
Affects Versions: 4.1.2
Environment: Hibernate 4.1.2, database n/a
Reporter: Shawn Clowater
There are 2 issues that came to light during extended testing of the Shared Transaction
impl.
1st issue is that when a Session is opened during a shared transaction scenario it
registers a TransactionObserver with the TransactionCoordinatorImpl to perform operations
such as managedFlush and manageClose calls on the child sessions. This observer is not
release until the transaction completes so even if the session is closed it can never be
garbage collected.
2nd issue is that the afterTransaction/beforeTransaction processes are registered with the
ActionQueue belonging to a Session and when the transaction coordinator completes the
transaction it only calls the afterTransactionCompletion on the Session that owns the
TransactionCoordinator and not any of the child sessions.
Originally suggested that the session remove itself from the observer list on close and
that the created observer should also call the before/after transaction methods but an
alternative solution was discussed where the TransactionCoordinator and not the
ActionQueue would be where the after transaction processes are registered. The
ActionQueue would register actions with the Coordinator vs. keeping its own lists.
Test cases showing both scenarios to follow shortly.

-------------------------------------
Added pull request @ https://github.com/hibernate/hibernate-orm/pull/307 that adds a few
unit tests showing some of the issues.
I added a third test that illustrates that currently if you have a managed session as the
secondary session and it is closed, either manually or automatically it will blow a
session already closed from the transaction observer if it is called after the session is
closed.

Added another pull request @ https://github.com/hibernate/hibernate-orm/pull/321
I think I might have hooped it up a bit since it picked up the initial commit as well that
had the tests. I couldn't figure out how to isolate it to the single commit. Let me
know if I've caused you undue grief.
