[Hibernate-JIRA] Created: (HSEARCH-821) Finalize SearchFactory API decisions

Finalize SearchFactory API decisions
------------------------------------
Key: HSEARCH-821
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-821
Project: Hibernate Search
Issue Type: Task
Reporter: Sanne Grinovero
Priority: Blocker
When introducing HSEARCH-750 we created these methods:
{code}org.hibernate.search.SearchFactory.openIndexReader(Class<?>...)
org.hibernate.search.SearchFactory.closeIndexReader(IndexReader){code}
An alternative idea would be to add a single indirection, as for example
searchFactory.getReaderProvider().open / close
This task is about taking a final decision on that matter, and review the SearchFactory API for other methods as well.

[Hibernate-JIRA] Created: (HV-495) Many locks on AnnotatedElements
by Loïc DIAS DA SILVA (JIRA)
Many locks on AnnotatedElements
-------------------------------
Key: HV-495
URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-495
Project: Hibernate Validator
Issue Type: Patch
Components: validators
Affects Versions: 4.2.0.CR1
Environment: GNU/Linux, JVM 6.0, Hibernate Validator 4.2.0.CR1
Reporter: Loïc DIAS DA SILVA
Attachments: jmeter-graph.docx, patch-ldds.patch
Hi all, we use Hibernate Validator 4.2.0-CR1 (previously Apache BVAL) for one of our API projects.
All is working fine for our needs except one big issue recently discovered during JMeter tests.
Several injectors make many requests from some Amazon cloud servers to our API and starting from a number of requests the response time begins to increase eavily, making a big jump from about 100ms in average to more than 5s.
After investigating we have seen many locks in some AnnotatedElement methods (mainly getAnnotation).
I've then made a little patch on hibernate in order to cache this kind of requests as i've not found any other cleaver/yet implemented way..
Since this patch all is working very well for us..
Regards.

[Hibernate-JIRA] Created: (HHH-6790) Add option to SequenceStyleGenerator to prefer a "sequence per entity"
by Steve Ebersole (JIRA)
Add option to SequenceStyleGenerator to prefer a "sequence per entity"
-----------------------------------------------------------------------
Key: HHH-6790
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6790
Project: Hibernate Core
Issue Type: New Feature
Components: core
Reporter: Steve Ebersole
Assignee: Steve Ebersole
Fix For: 4.1.0
Basically this is a RFE for a corollary to {{org.hibernate.id.enhanced.TableGenerator#CONFIG_PREFER_SEGMENT_PER_ENTITY}} for the {{org.hibernate.id.enhanced.SequenceStyleGenerator}}.
Currently, when no sequence name is given the default name (hibernate_sequence) is used. So this option would force {{org.hibernate.id.enhanced.SequenceStyleGenerator}} to determine a sequence name when none is explicitly given based on the name of the entity. The logic would be very similar to {{org.hibernate.id.enhanced.TableGenerator#determineDefaultSegmentValue}} but leveraging {{org.hibernate.id.IdentifierGenerator#ENTITY_NAME}} instead of {{org.hibernate.id.PersistentIdentifierGenerator#TABLE}}

[Hibernate-JIRA] Created: (HHH-5160) Error on binding values prepared statment in many-to-any relation

Error on binding values prepared statment in many-to-any relation
-----------------------------------------------------------------
Key: HHH-5160
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5160
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.1, 3.3.2
Environment: Tested on Version 3.3.2 and 3.5.1 on Oracle, PostgreSQL and MySQL
Reporter: wof
A Collection of Entities is defined as a ManyToAny relation, e.g.
@ManyToAny(metaColumn=@Column(name="C_OBJECT_TYPE"))
@AnyMetaDef(idType="string", metaType="string",
metaValues={
@MetaValue(targetEntity=Entity1.class, value="Entity1"),
@MetaValue(targetEntity=Entity2.class, value="Entity2")
})
@JoinTable(name="T_OBJECTS",
joinColumns=@JoinColumn(name="C_OWNER_ID"),
inverseJoinColumns=@JoinColumn(name="C_OBJECT_ID")
)
private Set<EntityBase> objects = new HashSet<EntityBase>();
Adding to this set works without problems. Removing all elements from the set (i.e. setting the set to null or zero-sized), too. However, when one or more elements are removed from the set with at least one element remaining, an exception is thrown:
org.hibernate.exception.GenericJDBCException: could not delete collection rows with the cause being java.sql.SQLException: Parameter index out of range (3 > number of parameters, which is 2).
I have narrowed this problem to this: The mapping table consists of 3 columns, C_OWNER_ID, C_OBJECT_TYPE and C_OBJECT_ID. The generated SQL-statement to delete the rows is as folling:
DELETE FROM t_objects WHERE c_owner_id=? AND c_object_id=?
However, Hibernate (in org.hibernate.typ.AnyType) tries to bind the actual value for c_object_id with index 3 which causes the exception. I guess Hibernate expects c_object_type to be present in the statement.
As workaround we changed nullSafeSet in AnyType to:
public void nullSafeSet(PreparedStatement st, Object value, int index, boolean[] settable, SessionImplementor session)
throws HibernateException, SQLException {
Serializable id;
String entityName;
if (value==null) {
id=null;
entityName=null;
}
else {
entityName = session.bestGuessEntityName(value);
id = ForeignKeys.getEntityIdentifierIfNotUnsaved(entityName, value, session);
}
// metaType is assumed to be single-column type
// <ORIGINAL CODE>
/*
if ( settable==null || settable[0] ) {
metaType.nullSafeSet(st, entityName, index, session);
}
if (settable==null) {
identifierType.nullSafeSet(st, id, index+1, session);
}
else {
boolean[] idsettable = new boolean[ settable.length-1 ];
System.arraycopy(settable, 1, idsettable, 0, idsettable.length);
identifierType.nullSafeSet(st, id, index+1, idsettable, session);
}
*/
// </ORIGINAL CODE>
// <PATCHED CODE>
if ( settable==null || settable[0] ) {
metaType.nullSafeSet(st, entityName, index, session);
boolean[] idsettable = new boolean[ settable.length-1 ];
System.arraycopy(settable, 1, idsettable, 0, idsettable.length);
identifierType.nullSafeSet(st, id, index+1, idsettable, session);
}
else if (settable==null) {
identifierType.nullSafeSet(st, id, index+1, session);
}
else {
boolean[] idsettable = new boolean[ settable.length-1 ];
System.arraycopy(settable, 1, idsettable, 0, idsettable.length);
identifierType.nullSafeSet(st, id, index, idsettable, session);
}
// </PATCHED CODE>
}
best regards
wof
