[Hibernate-JIRA] Created: (HHH-4832) Secondary tables do not work in JOINED or TABLE_PER_CLASS inheritance strategies

Secondary tables do not work in JOINED or TABLE_PER_CLASS inheritance strategies
--------------------------------------------------------------------------------
Key: HHH-4832

Project: Hibernate Core

I have a class hierarchy as follows:
{noformat}
Abstract RootClass (Mapped Superclass)
|
\ /
Abstract IntermediateClass (Entity)
| |
\ / \ /
LeafClass (Entity) LeafClass2 (Entity)
{noformat}
The following table shows which attributes are on each class:
||Class||Attribute||Table||
|RootClass|field1|rootclass|
|IntermediateClass|field2|intermediateclass|
|LeafClass|field3|leafclass|
|LeafClass|field4|leafclass2|
|AnotherLeafClass|field5|anotherleafclass|
|AnotherLeafClass|field6|anotherleafclass2|
Using {{InheritanceType.SINGLE_TABLE}}, it works.
Using {{InheritanceType.JOINED}} or {{InheritanceType.TABLE_PER_CLASS}} at the {{IntermediateClass}} level causes different errors:
Using {{InheritanceType.JOINED}} causes an incorrect insert statement which thinks that {{field4}} is on table {{leafclass}} rather than {{leafclass2}}:
{noformat}
Hibernate:
insert

LeafClass
(field1, field2, field3, field4, id)

[Hibernate-JIRA] Created: (HHH-2470) Use of session.createSQLQuery causes memory leak

Use of session.createSQLQuery causes memory leak
-------------------------------------------------
Key: HHH-2470
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2470
Project: Hibernate3
Type: Bug
Components: query-sql
Versions: 3.1.3
Environment: Win XP, Oracle 10g, Java 1.4.2
Reporter: Bjørn Bjerkeli
Attachments: TestCase.zip
NativeSQLQuerySpecification fails to properly implement equals and hashcode caused by lacking implementation of hashCode and equals in all SQLQueryReturn implementations and SQLQueryScalarReturn which are members of NativeSQLQuerySpecification. I can see that NativeSQLQuerySpecification has been changed in 3.2, but the problem is still there.
NativeSQLQuerySpecification instances are used as keys for retrieving and caching NativeSQLQueryPlan instances.
This causes the caching-mechanism to be pretty useless when Queries created by session.createSQLQuery because new entries will be added all the time in the QueryPlanCache and the SoftLimitMRUCache member.
So far so good, the more serious problem that is caused by this is stems from the implementation of SoftLimitMRUCache which again uses LRUMap in commons-collection. The put - method of the cache is not treadsafe, and that causes the following fragment in LRUMap to allow the map to grow beyond its maximumSize. That is bacause the containsKey method will return an incorrect result when concurrently updating the map.
public Object put( Object key, Object value ) {
int mapSize = size();
Object retval = null;
if ( mapSize >= maximumSize ) {
// don't retire LRU if you are just
// updating an existing key
if (!containsKey(key)) {
// lets retire the least recently used item in the cache
removeLRU();
}
}
retval = super.put(key,value);
return retval;
}
I have included a test-case that demonstrates:
1) Wrong implementation of equals and hashCode in NativeSQLQuerySpecification
2) Concurrent use of LRUMap causes the map to grow beyound it's max limit
3) Concurrent execution of session.createSQLQuery causes memory leak due to 1) and 2)
I would be more than happy to contribute to get this fixed. Just let me know.

Cascading performance problems when session contains many entities
------------------------------------------------------------------
Key: HHH-3221
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3221
Project: Hibernate3
Issue Type: Improvement
Components: core
Affects Versions: 3.3.0.CR1, 3.2.6, 3.2.5
Reporter: Yves Galante
Attachments: patchCascading.patch, SaveTest.zip
When session contains many entities, performence of cascading become very slow.
For each collection element the whole persistence context is searched (by StatefulPersistenceContext#getIndexInOwner() and StatefulPersistenceContext#getOwnerId) and its even searched twice when the collection is an indexed collection.
This patch optimize cascading operation by caching relation parent-child on a map.
eventSource.getPersistenceContext().addChildParent(child, parent);
action.cascade(eventSource, child, entityName, anything, isCascadeDeleteEnabled);
eventSource.getPersistenceContext().removeChildParent(child);
The test case save and flush 10 * 551 objects.
Before patch save object with cascading is more slow when session size grows.
After patch time of save stay same at each loop.
Output of the test case before the patch :
Save took 449 ms
Save took 669 ms
Save took 1042 ms
Save took 1464 ms
Save took 2481 ms
Save took 2741 ms
Save took 3807 ms
Save took 4344 ms
Save took 4975 ms
Save took 5251 ms
