[Hibernate-JIRA] Created: (HV-360) DefaultTraversableResolver.isReachable() should be enhanced to return true for validations with group other than Default

by Georges-Etienne Legendre (JIRA)

DefaultTraversableResolver.isReachable() should be enhanced to return true for validations with group other than Default ------------------------------------------------------------------------------------------------------------------------ Key: HV-360 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-360 Project: Hibernate Validator Issue Type: Improvement Affects Versions: 4.1.0.Final Reporter: Georges-Etienne Legendre Assignee: Hardy Ferentschik We use Bean Validator to validate transition between domain object states. We use groups to allow different validations for each state. When we want to change the state of an object, we get the object from the database (using JPA). However, because we use LAZY loading, only the loaded beans get validated. This causes problems because nothing is in fact validated (other than the first bean of course). I know the JSR tells that the default TraversableResolver should verify if JPA is in the classpath. However, this doesn't make sense when groups are used for the purpose described above. There are 2 workarounds: * Disable LAZY loading! * Implement a TraversableResolver that returns true for isReachable() However, I'm wondering if the DefaultTraversableResolver.isReachable() can be enhanced to return true for validations with group other than Default. -- 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-3571) Change the default revision entity configuration

by Adam Warski (JIRA)

Change the default revision entity configuration ------------------------------------------------ Key: HHH-3571 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3571 Project: Hibernate Core Issue Type: Task Components: envers Reporter: Adam Warski Assignee: Adam Warski Fix For: 3.4 The current revision table and field names are not accepted by databases such as Oracle. Hence: - change the revision entity name from _revision_entity to something acceptable by all databases (REVISION_ENTITY?) - change the revision field name from _revision (to revision?) Also, change the default id generation strategy from native to org.hibernate.id.enhanced.SequenceStyleGenerator Document those changes in the manual with a migration note! -- 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: (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
