[Hibernate-JIRA] Created: (HSEARCH-531) Use Lucene fieldcache

by Sanne Grinovero (JIRA)

Use Lucene fieldcache --------------------- Key: HSEARCH-531 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-531 Project: Hibernate Search Issue Type: Improvement Components: query Reporter: Sanne Grinovero Fix For: 3.4.0 The Lucene per-segment FieldCache should be used for strings we fetch from the index (Stored), by default as we do with classname and PK. It might be useful for people to be able to add more fields to this cache in case of projections usage. (It's purpose is to speed up this reading of stored info - being per segment it's not invalidated per new IndexReader but per changed segments). Likely need a switch to turn it off, as it could consume much memory. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-3121) Using fetch="subselect" and second level cache causes NullPointerException

by Adam Brod (JIRA)

Using fetch="subselect" and second level cache causes NullPointerException -------------------------------------------------------------------------- Key: HHH-3121 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3121 Project: Hibernate3 Issue Type: Bug Components: caching (L2) Affects Versions: 3.2.6 Environment: Oracle 10g Reporter: Adam Brod I've been tuning some of our mappings to use fetch="subselect" to reduce the number of DB queries. However, I have run into two cases where I get the exception below. In both cases, I was loading a list of Videos, which are mapped to a list of other objects. (In this example, Media is the superclass of Video.) I apologize that I can't upload a full working example, but I will include the relevant mapping info. <class name="Media" table="media" lazy="false" discriminator-value="0"> <cache usage="nonstrict-read-write"/> <id name="id" column="id" type="long"> <generator class="seqhilo"><param name="sequence">hibernate_hi_sequence</param><param name="max_lo">500</param></generator> </id> ... <list name="tags" lazy="true" table="media_tags" cascade="save-update" fetch="subselect"> <cache usage="nonstrict-read-write"/> <key column="media_id"/> <list-index column="idx"/> <many-to-many column="tag_id" class="com.brightcove.catalog.Tag"/> </list> ... <subclass name="Video" lazy="false" discriminator-value="1"> ... </subclass> </class> <class name="Tag" table="tag"> ... </class> The HQL being executed is just a simple "from Video v where v.publisher_id = :pubId". The line of code where the exception is generated in Video.getDTO() is accessing the Tags list: for (Tag tag : getTags()) { tags.add(tag.getDTO()); } I've debugged into the Hibernate source to see where the NPE comes from (CollectionLoadContext line 298). if ( persister.isVersioned() ) { versionComparator = persister.getOwnerEntityPersister().getVersionType().getComparator(); final Object collectionOwner = getLoadContext().getPersistenceContext().getCollectionOwner( lce.getKey(), persister ); version = getLoadContext().getPersistenceContext().getEntry( collectionOwner ).getVersion(); //NPE! } It seems that "collectionOwner" is null, so calling getEntry(collectionOwner) returns null. Calling getVersion() on a null entry is what throws the NPE. java.lang.NullPointerException at org.hibernate.engine.loading.CollectionLoadContext.addCollectionToCache(CollectionLoadContext.java:298) at org.hibernate.engine.loading.CollectionLoadContext.endLoadingCollection(CollectionLoadContext.java:256) at org.hibernate.engine.loading.CollectionLoadContext.endLoadingCollections(CollectionLoadContext.java:222) at org.hibernate.engine.loading.CollectionLoadContext.endLoadingCollections(CollectionLoadContext.java:195) at org.hibernate.loader.Loader.endCollectionLoad(Loader.java:877) at org.hibernate.loader.Loader.initializeEntitiesAndCollections(Loader.java:865) at org.hibernate.loader.Loader.doQuery(Loader.java:729) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:236) at org.hibernate.loader.Loader.loadCollectionSubselect(Loader.java:2066) at org.hibernate.loader.collection.SubselectCollectionLoader.initialize(SubselectCollectionLoader.java:58) at org.hibernate.persister.collection.AbstractCollectionPersister.initialize(AbstractCollectionPersister.java:565) at org.hibernate.event.def.DefaultInitializeCollectionEventListener.onInitializeCollection(DefaultInitializeCollectionEventListener.java:60) at org.hibernate.impl.SessionImpl.initializeCollection(SessionImpl.java:1716) at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:344) at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86) at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:109) at org.hibernate.collection.PersistentList.size(PersistentList.java:91) at com.brightcove.catalog.EconomicEntity.populateDTO(EconomicEntity.java:460) at com.brightcove.catalog.Media.populateDTO(Media.java:192) at com.brightcove.catalog.Video.populateDTO(Video.java:854) at com.brightcove.catalog.Video.getDTO(Video.java:783) at com.brightcove.catalog.Video.getDTO(Video.java:756) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-687) orm.xml - cleanup respecting column names

by darren hartford (JIRA)

orm.xml - cleanup respecting column names ----------------------------------------- Key: ANN-687 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-687 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.0.ga Environment: mysql 5, MS SQL 2000, Win2000, hibernate 3.2.4 Reporter: darren hartford couple of issues with orm.xml mapping file that is not fully implemented and needs cleanup. many-to-many table mapping not respecting column names. http://forum.hibernate.org/viewtopic.php?t=982330 id-class not respecting column names (end of an old issue, repeated with different scenario). http://opensource.atlassian.com/projects/hibernate/browse/ANN-361 <id-class class="MyTestId"/> <attributes> <id name="compoundOne"> <column name="COMPOUND_ONE"/> </id> <id name="compoundTwo"> <column name="COMPOUND_TWO"/> </id> ... WARNING: Preparing the statement failed: Invalid column name 'compoundOne'. WARNING: Preparing the statement failed: Invalid column name 'compoundTwo'. ========== Use case and urgency of issue related to external technology integration. -DTO should not require hibernate-annotations to be used in client-code, but is required when using annotations. orm.xml approach removes this limitation. -GWT 1.4 does not work with java 1.5/annotated DTO. Although everyone keeps pushing it off saying 'GWT 1.5 is on the way', it is not and solutions that should have been working to work around that limitation need to be working correctly. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-5056) Criteria API with ProjectionList and Unique result

by Ahmed Ali Elsayed Ali Soliman (JIRA)

Criteria API with ProjectionList and Unique result -------------------------------------------------- Key: HHH-5056 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5056 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.5.0-CR-2 Environment: Hibernate 3.3.2, Oracel 11g Reporter: Ahmed Ali Elsayed Ali Soliman Priority: Critical when you make a select statement with Criteria API & use ProjectionList to retrieve some columns then use the unique result make at least 2 projection list (2 columns or more) ProjectionList projectionList = Projections.projectionList() .add(Projections.property("ColumnA")) .add(Projections.property("ColumnB")); criteria.setResultTransformer(CriteriaSpecification.DISTINCT_ROOT_ENTITY); the result must be retrieved in 2 dimensional array of Object(Object[][]) but the result are one dimensional array with one column only. Note:- when you remove the unique result it works fine but when you add it, it make this behavior. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-472) @UniqueConstraint declaration is not friendly towards inheritance or reflection

by Ted Bergeron (JIRA)

@UniqueConstraint declaration is not friendly towards inheritance or reflection ------------------------------------------------------------------------------- Key: ANN-472 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-472 Project: Hibernate Annotations Type: Improvement Versions: 3.2.0.ga Environment: Hibernate 3.2 GA Reporter: Ted Bergeron The current way to define a composite unique constraint is limiting. @Table(name="tbl_sky", uniqueConstraints = {@UniqueConstraint(columnNames={"month", "day"})} ) Suppose I have an abstract base class called A that gives me Id and Name, subclassed by abstract class B that gives me Customer. Then I have many concrete classes that subclass B. For all of these, I'd want the combination of Name and Customer to be unique. As I do not use @Table with abstract base classes, I currently have to repeat: uniqueConstraints = {@UniqueConstraint(columnNames={"name", "customer_id"})} on all concrete classes. If we had an alternate way to define these constraints at the property level (as XDoclet did with hibernate 2), I could define this in the base classes and inherit the constraint declaration. The other need is that I would like to use reflection to scan the properties and apply proper validations in the view layer. With @Column(unique = true) this is easy to do. The view layer makes an AJAX call and all is well. For a composite constraint, it does not work well currently. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (EJB-397) native SQL queries in hibernate don't work when using aliases to differentiate columns that have the same name

by Alex McCarrier (JIRA)

native SQL queries in hibernate don't work when using aliases to differentiate columns that have the same name -------------------------------------------------------------------------------------------------------------- Key: EJB-397 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-397 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.2.GA Environment: jboss 4.2.2, mysql 5 Reporter: Alex McCarrier Basically same as HHH-2094, if you do something like this: select oldForm.data as oldData newForm.data as newData from form oldForm, join form newForm on oldForm.replaced_by_id = newForm.id then use entityManager.createNativeQuery(sql).getResultList() it will end up with an error that says column named oldData does not exist. If you take out the aliases, then it will just return the first value for "data" for every column. If you run this through straight JDBC with the alias, it works as expected. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-4939) Bidirectional OneToOne mapping with FK and composite PK sharing a column throws MappingException

Bidirectional OneToOne mapping with FK and composite PK sharing a column throws MappingException ------------------------------------------------------------------------------------------------ Key: HHH-4939 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4939 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Reporter: Chris Wilson Attachments: HibernateAnnotationMappingOneToOneTest.java A bidirectional one-to-one mapping, where the owning side's column is part of a composite primary key, fails to configure, possibly because OneToOneType#getColumnSpan returns zero instead of the actual number of columns used by the join.
