[Hibernate-JIRA] Created: (HHH-2223) BatchFetchQueue.getXXXBatch() cache check impeding batch fetching

BatchFetchQueue.getXXXBatch() cache check impeding batch fetching
-----------------------------------------------------------------
Key: HHH-2223
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2223
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.ga
Environment: 3.2.0GA, Mac OS X/Solaris 10, Sybase 12.5/HSQLDB
Reporter: Joel Caplin
Priority: Minor
Attachments: testcase.tar
I have attached a test case which demonstrates the issue at hand by implementing a cheap data model: Pub >---|- Manager -|--< Employee
Pub and Employee are uncached; Manager is cached (tried under both Eh and the non-prod HashMap implementation). All associations are lazy. The test case has a default batch size of 10 and uses hsqldb to demonstrate the problem - which was diagnosed against Sybase.
When BatchFetchQueue.getXXXBatch() is invoked, it does not load any objects it finds in the second level cache - it merely acknowledges their presence by logging to INFO (isCached()). This in turn means that any child associations in that cached object will not have a proxy created for them.
Suppose we want to find all the employees of the pubs in our database. We choose to do this by loading all the Pubs ("FROM Pub") and calling thePub.getManager().getEmployees() iteratively.
When the managers are in the second level cache, Hibernate issues 11 select statements: one to load the pubs and one for each distinct manager.
When the Managers are not in the cache, Hibernate issues 3 select statements: one to load the pubs, one to load the managers and one to load the employees.
A solution might be to load the object from the cache instead of just ignoring it?

For the following mapping:
{code}
public class AnEntity extends HibernatePersistedObject {

public class TargetEntity {

add(AuditEntity.id().eq(id)).addOrder(AuditEntity.revisionNumber().desc()).

I get an NPE because the there is no EntityConfiguration for TargetEntity, as it is not audited:

Criteria.createAlias not working for key-many-to-one associations of a composite-id
-----------------------------------------------------------------------------------
Key: HHH-4591
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4591
Project: Hibernate Core
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.3.2, 3.2.7, 3.2.6
Environment: Hibernate 3.2.6.ga, 3.2.7.ga, 3.3.2.ga
Database: Oragle10g
Reporter: Luka
I'm trying to create an alias to apply a filter on a composite primary-key association, but I'm getting an invalid SQL generated by the ctiteria api: in the SQL there is the filter applied in the where, but the join for the alias is missing in the from.
Here is a sample of the problem:
Mappings (I stripped non relevant info):
TableOne.hbm.xml
<hibernate-mapping default-cascade="none">
<class name="TableOne" table="TABLE_ONE" dynamic-insert="false" dynamic-update="false">
<id name="idTableOne" type="java.lang.Long" unsaved-value="null">
<column name="ID_CONTRATTO"/>
<generator class="sequence">
<param name="sequence">S_TABLE_ONE</param>
</generator>
</id>
<set name="tableOneToTableTwo" order-by="ID_TABLE_ONE" lazy="true" fetch="select" inverse="true" cascade="none">
<key>
<column name="ID_TABLE_ONE"/>
</key>
<one-to-many class="TableOneToTableTwo"/>
</set>
</class>
</hibernate-mapping>
TableOneToTableTwo.hbm.xml
<hibernate-mapping default-cascade="none">
<class name="TableOneToTableTwo" table="TABLE_ONE_TO_TABLE_TWO" dynamic-insert="false" dynamic-update="false">
<composite-id name="tableOneToTableTwoPk" class="TableOneToTableTwoPK">
<key-many-to-one name="tableOne" class="TableOne" >
<column name="ID_TABLE_ONE"/>
</key-many-to-one>
<key-many-to-one name="tabelTwo" class="TabelTwo" >
<column name="ID_TABLE_TWO"/>
</key-many-to-one>
</composite-id>
</class>
</hibernate-mapping>
TabelTwo.hbm.xml
<hibernate-mapping default-cascade="none">
<class name="TabelTwo" table="TABLE_TWO" dynamic-insert="false" dynamic-update="false">
<id name="idTableTwo" type="java.lang.Long" unsaved-value="null">
<column name="ID_TABLE_TWO"/>
<generator class="sequence">
<param name="sequence">S_TABLE_TWO</param>
</generator>
</id>
<property name="codTabelTwo" type="java.lang.String">
<column name="COD_TABLE_TWO" not-null="true" unique="false"/>
</property>
</class>
</hibernate-mapping>
Code:
Criteria hibCrit = getSession().createCriteria(TableOne.class);
hibCrit.createAlias("tableOneToTableTwo", "tableOneToTableTwo");
hibCrit.createAlias("tableOneToTableTwo.tableOneToTableTwoPk.tabelTwo", "tabelTwo");
hibCrit.add(Restrictions.eq("tabelTwo.codTabelTwo", "AAA"));
hibCrit.list();
Generated SQL using Oracle10G dialect (I stripped columns in select):
SELECT [...]
FROM TABLE_ONE this_
INNER JOIN TABLE_ONE_TO_TABLE_TWO tabelTwoco1_ ON this_.ID_TABLE_ONE = tabelTwoco1_.ID_TABLE_ONE
WHERE tabelTwo2_.COD_TABLE_TWO = ?
The "tabelTwo2_" should be the sql alias for criteria alias "tabelTwo", but the table and the join are missing in the from...
I also tried using createCriteria:
Criteria hibCrit = getSession().createCriteria(TableOne.class);
hibCrit.createAlias("tableOneToTableTwo", "tableOneToTableTwo");
Criteria tableTwoCrit = hibCrit.createCriteria("tableOneToTableTwo.tableOneToTableTwoPk.tabelTwo", "tabelTwo");
tableTwoCrit.add(Restrictions.eq("tabelTwo.codTabelTwo", "AAA"));
hibCrit.list();
But i get the same sql query.
Also upgrading Hibernate result in the same behavior.

Fix For: 3.5
It seems that some filter implementations are allowed to return null instead of an empty iterator if they don't match any document.
In this case if multiple filters are enabled, and they are eligible for bitset merging, and no matches where found, we get:

[Hibernate-JIRA] Created: (HHH-3706) Audit Table Schema not generated using <annotationconfiguration>

Audit Table Schema not generated using <annotationconfiguration>

The Ant task to generate the schema for the audit tables generates schema for my entities but none of the Audit tables are. I have used the org.hibernate.tool.ant.EnversHibernateToolTask class.
<target name="schemaexport" depends="compile" description="Exports a generated schema to DB and file">
<taskdef name="hibernatetool" classname="org.hibernate.tool.ant.EnversHibernateToolTask" classpathref="hibernate" />
<hibernatetool destdir=".">

<jpaconfiguration persistenceunit="ConsolePU"/>
<hbm2ddl drop="false" create="true" export="false" outputfilename="versioning-ddl.sql" delimiter=";" format="true" />
</hibernatetool>
</target>
It works on using <jpaconfiguration>.
