@TableGenerator does not increment pkColumnValue by allocationSize
------------------------------------------------------------------
Key: HHH-3407
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3407
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6, 3.2.4
Environment: JBoss 4.2.3, RHEL4, JDK1.5
Reporter: Dan Ciarniello
According to the JPA, the allocationSize attribute to @TableGenerator is "The amount to increment by when allocating id numbers from the generator" but the value is actually incremented by 1 regardless of allocationSize. The id is generated properly apparently according to the formula
id = lastkeyval*allocationSize + i where 0<i<allocationSize
The problems with this algorithm are:
1. One cannot tell what the next key value range is from the key table without knowing the allocationSize (minor)
2. If the allocationSize is reduced, already existing key values will be generated (major)
3. If two applications are configured with different allocation sizes, there will be an overlap in generated values (major)

Add StartRevision/EndRevison fileds to audit tables
---------------------------------------------------
Key: HHH-3709
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3709
Project: Hibernate Core
Issue Type: Improvement
Components: envers
Affects Versions: 3.4
Reporter: jason shi
In Envers audit tables(eg:Person_Aud), two fields added:REV,REVTYPE
When retrieve data at special REV, a sql with subselect executed:
select a.id, a.REV, a.REVTYPE, a.name, a.surname, a.address_id
from Person_AUD a
where a.REVTYPE <> ? and a.id = ?
and a.REV = (select max(b.REV) from Person_AUD b where b.REV <= ? and a.id = b.id)
The sql performance is poor.
I suggest adding StartRevision/EndRevison fileds to the audit tables,replace the REV field.
The StartRevision equals the original REV field,EndRevision will be filledd when this record changed in next Revision.
The new query sql will like this:
select a.id, a.REV, a.REVTYPE, a.name, a.surname, a.address_id
from Person_AUD a
where a.REVTYPE <> ? and a.id = ?
and a.StartRevision<=? and a.EndRevision>?

[Hibernate-JIRA] Created: (HHH-2131) SYBASE +select for update is showing deadlock because lock is not working properly

SYBASE +select for update is showing deadlock because lock is not working properly
----------------------------------------------------------------------------------
Key: HHH-2131
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2131
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.1.3
Environment: sybaseASE 12.5.03 in solaris +hibernate3.1.3
Reporter: George Thomas
I am connecting to Sybase database from hibernate.I tried setting locks using while selecting rows
1.session.load(class,id,LOCKMODE.UPGRADE)
2.session.lock(obj,LOCKMODE.UPGRADE)
I am attaching a sample code while updating a field in table fund after selecting it.
{
Fund fund = null;
ClientCredential credential = new ClientCredential("testDatabase", fund);
org.hibernate.Session session = SessionFactoryManager.getSessionFactory(credential).getCurrentSession();
Transaction transaction = session.beginTransaction();
log.info("Run by " + Thread.currentThread().getName());
fund = (Fund) session.get(Fund.class, new Short((short)12), LockMode.UPGRADE);
fund.setLegalEntityOrgId(fund.getLegalEntityOrgId()+1);
transaction.commit();
}
my requirement was that i wanted to do a select for update.I should acquire lock on certain rows and do a matching and if concurrent request comes ,it should wait till transaction is over that is lock is released.
When I went through the hibernate code,the hibernate is making static queries in the beginning while loading session factory.Since we are appending the holdlock during execution,the sybase dialect is not appending.
As a work around I tested with native sql with holdlock but when I test concurrent request using threads its bombing.Its throwing LockAcquisitionException.( Your server command (family id #0, process id #3777) encountered a deadlock situation.).can anyone give a solution to this problem???

@Where clause may trigger an ambiguous column error
---------------------------------------------------

Project: Hibernate Annotations
Issue Type: Bug
Components: binder
Affects Versions: 3.3.1.GA
Environment: Hibernate Core 3.3.1GA, Annotations 3.4.0GA, PostgreSQL 8.3
Reporter: Bob Harrod
Attachments: LoginUnit.java, LoginUnitUser.java, LoginUser.java
The following annotations are being used to simulate a soft delete strategy:
@Entity
@Table(name = "login_unit_user")
@SQLDelete( sql="UPDATE login_unit_user SET _is_active = 0 WHERE id = ?")
@Where(clause="_is_active <> 0")
public class LoginUnitUser extends DomainObject implements Serializable{...}

@Entity
@Table(name = "login_unit")
@SQLDelete( sql="UPDATE login_unit SET _is_active = 0 WHERE id = ?")
@Where(clause="_is_active <> 0")
public class LoginUnit extends DomainObject implements Serializable{...}
In the attached code, both LoginUnit and LoginUnitUser contain a system column - "_is_active". This column represents a flag which indicates whether or not the row is "active" or "deleted". When these two hibernate model objects are queried, hibernate does not properly append the table alias to this additional where clause that it uses during it's database query. The error raised is:

[Hibernate-JIRA] Created: (HHH-2374) setFetchMode() ignore incorect path
by Baptiste MATHUS (JIRA)
setFetchMode() ignore incorect path
-----------------------------------
Key: HHH-2374
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2374
Project: Hibernate3
Type: Bug
Versions: 3.2.0.ga
Environment: All DB I guess
Reporter: Baptiste MATHUS
This bug report is in fact a copy of the one that was already present in H2 : http://opensource.atlassian.com/projects/hibernate/browse/HB-763 . It does not seem to have changed in H3.
When calling setFetchMode("path", FetchMode.JOIN) on a criteria, even if the path is not correct, Hibernate does not complain. Its behaviour seems to be to simply ignore this bad path. I guess this should throw an exception. In fact, the bad thing of ignoring bad path is that if the developer was wrong specifying the path (typo, for example), then the join simply won't happen :-/.
I wrote a very simple testcase :
public void testFindClients()
{
Session session = HibernateUtil.currentSession();
session.beginTransaction();
Client c = (Client)session.createCriteria(Client.class).setFetchMode("foo", FetchMode.JOIN)
.setFetchMode("foo.bar", FetchMode.JOIN).uniqueResult();
session.getTransaction().commit();
}
My Client class has some relationships with other classes, but obviously none named "foo". The code above just issue the following select :
select
this_.ID as ID0_0_,
this_.nom as nom0_0_,
this_.prenom as prenom0_0_,
this_.age as age0_0_
from
Client this_
Thanks again for your great work, guys!

[Hibernate-JIRA] Created: (HHH-2344) Persistent collection queued operation ignored with lazy inverse one-to-many collection.
by Sebastien Robert (JIRA)
Persistent collection queued operation ignored with lazy inverse one-to-many collection.
----------------------------------------------------------------------------------------
Key: HHH-2344
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2344
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.1
Environment: Hibernate 3.2.1
Reporter: Sebastien Robert
I load an Object that contains a lazy inverse collection (one-to-many).
Hibernate wrap my collection with a PersistentMap
There is objects in the collection in the database but in my case the PersistentMap is not yet initialized.
I perform a remove operation on the persistentMap with a known key of one of the objects.
The map is not initialized (and the relation is an inverse one-to-many) so the map queue the removeOperation.
I perform a get operation with the same key and the value is still returned.
If we look closer at what happened in the PersistentMap, it's look like this.
//*****
public Object remove(Object key) {
if ( isPutQueueEnabled() ) { // This returned true, the
// map is not yet
// initialized
Object old = readElementByIndex( key ); // This method triggered
// an initialization of the
// map.
// Queued operation are
// processed in the after
// init method
queueOperation( new Remove( key, old ) ); // The remove operation
// is queued.
return old;
}
....
//*******
When i perform the get operation on the map the map is now initialized. The get is processed by the underlying map and the value is returned. The queued operation is completely ignored.
Currently i fixed my code by performing a containsKey before the remove . The containsKey initialize the map and then the remove do not queue the operation. But by looking at all the PersistentCollection it seem that i may have the same problem using put and remove with other persistentCollection.
