[Hibernate-JIRA] Created: (HHH-2955) Unnecessary version updates in two cases.

by Sławomir Wojtasiak (JIRA)

Unnecessary version updates in two cases. ----------------------------------------- Key: HHH-2955 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2955 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: JDK 5.0 Reporter: Sławomir Wojtasiak Attachments: HibernateTest.zip I found two situations where hibernate generates unnecessary version updates. Let's illustrate it with a simple example: Session session = SessionFactory.getSession(); Transaction transaction = session.getTransaction(); transaction.begin(); Article a = new Article(); a.setName( "atricle" ); ********************************************* *** Quantity is the owner of the relation *** ********************************************* Quantity q = new Quantity(); q.setName( "quantity" ); q.setArticle( a ); a.getQuantities().add( q ); session.persist( a ); session.flush(); ***** Hibernate generates following SQLs ***** Hibernate: select nextval ('hibernate_sequence') Hibernate: select nextval ('hibernate_sequence') Hibernate: insert into Article (name, version, id) values (?, ?, ?) Hibernate: insert into Quantity (article_id, name, version, id) values (?, ?, ?, ?) ********************************************** a.getQuantities().clear(); session.flush(); *** Hibernate generates following SQLs *** Hibernate: update Article set name=?, version=? where id=? and version=? This update of version field is performed because collection of quantities is marked as dirty, but Article entity is not relation owner so nothing change in database after this clear. Should it works like this? It looks like a bug because database remain unchanged so version changing is unnecessary in my opinion. ****************************************** session.clear(); **** SECOND PROBLEM *** Now I generate true copy of persisted objects. Notice that I use HashSet instead of PersistSet which was set during persist operation. This operation is similar to merging objects prepared by SOAP, during communication with remote client for example. *********************** Article a1 = new Article(); a1.setId( a.getId() ); a1.setName( a.getName() ); a1.setVersion( a.getVersion() ); Quantity q1 = new Quantity(); q1.setArticle( a1 ); q1.setName( q.getName() ); q1.setVersion( q.getVersion() ); q1.setId( q.getId() ); a1.getQuantities().add( q1 ); a1 = (Article)session.merge( a1 ); session.flush(); ***** This operation generates following SQLs ***** Hibernate: select article0_.id as id0_1_, article0_.name as name0_1_, article0_.version as version0_1_, quantities1_.article_id as article4_3_, quantities1_.id as id3_, quantities1_.id as id1_0_, quantities1_.article_id as article4_1_0_, quantities1_.name as name1_0_, quantities1_.version as version1_0_ from Article article0_ left outer join Quantity quantities1_ on article0_.id=quantities1_.article_id where article0_.id=? Hibernate: update Article set name=?, version=? where id=? and version=? It looks like problem is located in replaceElements() method of CollectgionType class (or somewhere near it). Maybe I'm wrong but this collection was checked for changes during merge operation (See this select above.) so why it remains dirty if it contains the same data as database?. I checked this issue on other JPA implementations (OpenJPA for example) and version is not incremented after similar merge operation. ***************************************************** transaction.rollback(); -- 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-318) PostUpdate callback not called after update on a collection / association (@OneToMany for example)

by Aghnar von Salza (JIRA)

PostUpdate callback not called after update on a collection / association (@OneToMany for example) -------------------------------------------------------------------------------------------------- Key: EJB-318 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-318 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Environment: Hibernate core3.2.5, entityManager 3.3.1, annotation 3.3.0, oracle 9i Reporter: Aghnar von Salza Environment is Weblogic 10 (J2EE 5), with Hibernate used as JPA provider There is no PostUpdate callback on an entity when one of its collections of other Entities (for example annoted with @OneToMany) is updated (i mean when one entity element is added or removed). JPA specification says that a postUpate must be called after the update of at least one data of an entity. I think we have to consider that a collection of other entities can be considered as data. -- 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-5580) tracking entity names in a revision

by Vardan Akopian (JIRA)

tracking entity names in a revision ----------------------------------- Key: HHH-5580 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5580 Project: Hibernate Core Issue Type: New Feature Components: envers Affects Versions: 3.5.5 Environment: hibernate 3.5.5 Reporter: Vardan Akopian Attachments: envers-entity-names.patch Currently Envers provides no way of finding which entities have been affected in a given revision. I.e. given a revision number it's impossible to find all the versions of all the entities for that revision. For example, all the search methods in the AuditQuery API take the entity class as a parameter. In our application we need to be able to retrieve all the changes for a given revision number without prior knowledge of which entities have been modified. Similar questions and requests have been posted in the envers forums before. The attached patch has a simple implementation for this feature. It adds 2 simple methods to the RevisionListener interface, that are called from AuditProcess and allow the Revision Entity to keep track of the entity names that are changed. The test cases show the simple usage for this. -- 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

by Amit Kapoor (JIRA)

NPE while query.list on a Native SQL, using L2 cache ---------------------------------------------------- Key: HHH-3051 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3051 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5ga Database Oracle 9i Jdk - 1.4.2_13 EHCache 1.2.3 / OsCache 2.1 both Reporter: Amit Kapoor I get an NPE when i try to execute a native query. Below is the excerpt of the code that throws NPE: String sqlQuery = "select emp_id, emp_first_name from employee_mt"; SQLQuery query = session.createSQLQuery(sqlQuery); query.setCacheable(true).setCacheRegion("TEST_REGION"); query.addScalar("emp_id"); query.addScalar("emp_first_name"); List list = query.list(); query.list() throws the following NPE: java.lang.NullPointerException at org.hibernate.type.TypeFactory.disassemble(TypeFactory.java:451) at org.hibernate.cache.StandardQueryCache.put(StandardQueryCache.java:83) at org.hibernate.loader.Loader.putResultInQueryCache(Loader.java:2194) at org.hibernate.loader.Loader.listUsingQueryCache(Loader.java:2138) at org.hibernate.loader.Loader.list(Loader.java:2096) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:289) at org.hibernate.impl.SessionImpl.listCustomQuery(SessionImpl.java:1695) at org.hibernate.impl.AbstractSessionImpl.list(AbstractSessionImpl.java:142) at org.hibernate.impl.SQLQueryImpl.list(SQLQueryImpl.java:152) at poc.hibernate.caching.QueryCaching.fireNativeSql(QueryCaching.java:112) at poc.hibernate.caching.QueryCaching.fireQuery(QueryCaching.java:38) at poc.hibernate.caching.QueryCaching.main(QueryCaching.java:27) I tried tracing through the Hibernate code code and saw that the types[] in the at the time of execution of types[i].disassemble( row[i], session, owner ) (TypeFactory.disassemble()) was holding both the types as null. However before reaching that piece of code CustomLoader.autoDiscoverTypes(resultset) had already resolved the resultTypes to appropriate values. Hope this helps. -- 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-5965) In JPA 2.0 no way to use SINGLE_TABLE for entity subclass included in associations @OneToMany

by Andrea Folli (JIRA)

In JPA 2.0 no way to use SINGLE_TABLE for entity subclass included in associations @OneToMany --------------------------------------------------------------------------------------------- Key: HHH-5965 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5965 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.6.1 Environment: All Reporter: Andrea Folli Priority: Critical We use SINGLE_TABLE Mapping Strategy to collapse on a single table several Entity Classes sharing a lot of persistent fields. When two of these entities are associated to a master entity via @OneToMany and we load the master entity with FetchType.EAGER for the two associations, we get a ClassCastException due to a bad behavoiur of Hibernate.. In fact it loads for both associtions all the entities associated by FK to the master entity, (regrdless of Discriminator Values). We know there is the @ForceDiscriminator annotations, but there is not an equivalento in JPA 2.0 implemenmtation, Please can you reveal your strategy for this issue? -- 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
