Developing a new IndexReader I made a stress-test to compare performance to base readers, but got this when measuring SharedReaderProvider:

[Hibernate-JIRA] Created: (HSEARCH-305) Hibernate search doesn't work with criteria when it is not initialized laziily

Hibernate search doesn't work with criteria when it is not initialized laziily
------------------------------------------------------------------------------
Key: HSEARCH-305
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-305
Project: Hibernate Search
Issue Type: Bug
Components: query
Affects Versions: 3.0.1.GA
Environment: MYSQL,HIBERNATE 3.0 , Flex with dpHibernate
Reporter: prabhu lal
Attachments: QueryLoader.java
For the RIA applications complete object tree should be initialized(To achieve that there is work around available like dpHibernate). But hibernate search doesn't apply criteria to queried result because it returns the result on the basis of wether objectt is intialized by loading the criteria objects.Since there is no lazy intiaialization so all the objects are loaded andcomplete result will be return irrespctive of criteria.
code snipet from Hibernate Search API(org.hibernate.search.engine.QueryLoader.java.):
public List load(EntityInfo... entityInfos) {
final int maxResults = entityInfos.length;
if ( maxResults == 0 ) return EMPTY_LIST;
if ( entityType == null ) throw new AssertionFailure( "EntityType not defined" );
if ( criteria == null ) criteria = session.createCriteria( entityType );
DocumentBuilder builder = searchFactoryImplementor.getDocumentBuilders().get( entityType );
String idName = builder.getIdentifierName();
int loop = maxResults / MAX_IN_CLAUSE;
boolean exact = maxResults % MAX_IN_CLAUSE == 0;
if ( !exact ) loop++;
Disjunction disjunction = Restrictions.disjunction();
for (int index = 0; index < loop; index++) {
int max = index * MAX_IN_CLAUSE + MAX_IN_CLAUSE <= maxResults ?
index * MAX_IN_CLAUSE + MAX_IN_CLAUSE :
maxResults;
List ids = new ArrayList( max - index * MAX_IN_CLAUSE );
for (int entityInfoIndex = index * MAX_IN_CLAUSE; entityInfoIndex < max; entityInfoIndex++) {
ids.add( entityInfos[entityInfoIndex].id );
}
disjunction.add( Restrictions.in( idName, ids ) );
}
criteria.add( disjunction );
criteria.list(); //load all objects
//mandatory to keep the same ordering
List result = new ArrayList( entityInfos.length );
for (EntityInfo entityInfo : entityInfos) {
Object element = session.load( entityInfo.clazz, entityInfo.id );
if ( Hibernate.isInitialized( element ) ) { //This is true for all the objects,in case objects are eagrly intialized
//all existing elements should have been loaded by the query,
//the other ones are missing ones
result.add( element );
}
}
return result;
}

[Hibernate-JIRA] Created: (HSEARCH-362) When using hibernate-search3.1.0 GA, Search throws AlreadyClosedException under certain circumstances

When using hibernate-search3.1.0 GA, Search throws AlreadyClosedException under certain circumstances
-----------------------------------------------------------------------------------------------------
Key: HSEARCH-362
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-362
Project: Hibernate Search
Issue Type: Bug
Components: directory provider
Affects Versions: 3.1.0.GA
Environment: Hibernate 3.2.6 GA, ant 1.7.1
Reporter: S Ravi Bhaskar
The below code throws an AlreadyClosedException when trying to open the lucene index. Junit test to test it works from eclipse, fails in an ant build.
I suspect it is trying to reuse a handle to the index. Please let me know if you need more information.
I had to bump back my hibernate search version to 3.0.1 GA, and then it started working. I am getting by, but would ideally like to use 3.1.0 GA without this exception. I think it has something to do with Search.getFullTextEntityManager((getJpaPersistenceContext().getEntityManager())); VS Search.createFullTextEntityManager((getJpaPersistenceContext().getEntityManager())); in the older version.
String query = "BlahBlahBlah";
org.apache.lucene.queryParser.QueryParser parser = new QueryParser("ItemTitle", new StandardAnalyzer() );
org.apache.lucene.search.Query luceneQuery;
try {
luceneQuery = parser.parse(query);
} catch (ParseException e) {
// TODO Auto-generated catch block
logger.error(String.format("Error parsing search querystring "));
return null;
}
javax.persistence.Query fullTextQuery = createFullTextEntityManager().createFullTextQuery(luceneQuery, klass);
List result = fullTextQuery.getResultList(); // return a list of managed
where createFullTextEntityManager() is
public FullTextEntityManager createFullTextEntityManager() {
return Search.getFullTextEntityManager((getJpaPersistenceContext().getEntityManager()));
}

[Hibernate-JIRA] Created: (HHH-3395) Oracle LONG datatype fetching fails on superclass Criteria query

Oracle LONG datatype fetching fails on superclass Criteria query
----------------------------------------------------------------
Key: HHH-3395
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3395
Project: Hibernate3
Issue Type: Bug
Environment: Oracle 10
Windows XP
Hibernate 3
Weblogic 9.2
Reporter: Ville Anttonen
I have dao-layer method like this.
public PersistentQuery getPersistentQuery(String userId, long queryId){
....
Criteria criteria = m_session.createCriteria(PersistentQuery.class);
criteria.add(Expression.eq("userId",userId));
criteria.add(Expression.eq("id",new Long(queryId)));
return (PersistentQuery) criteria.uniqueResult();
.....
}
Previous code throws "Stream already closed" exception.
PersistentQuery is abstract class
and it's subclasses contains UserType - field
that wraps Oracle's long varchar field.
I can fix this by creating criteria by subclass
like " Criteria criteria = m_session.createCriteria(PersistentOrganizationQuery.class); ".
We're migrating from ingres -> oracle and in ingres previous implementation worked fine.
