[Hibernate-JIRA] Created: (HHH-3836) composite-element with null columns in map is ignored

by Benoit Goudreault-Emond (JIRA)

composite-element with null columns in map is ignored ----------------------------------------------------- Key: HHH-3836 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3836 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.0.SP1 Environment: 3.3.0 SP1, noticed with Oracle and H2 but probably happens with all databases Reporter: Benoit Goudreault-Emond Attachments: patate.zip When a composite element with all properties set to NULL is inserted in a map of the said composite element, the data gets inserted to the database but is never retreived when reloading the entity. For instance, with an entity @Entity public class TestEntity { @Id private int id; @CollectionOfElements private Map<String, AccessPeriod> roleAccesses = new HashMap<String, AccessPeriod>(); // boilerplate getters/setters/etc omitted } And AccessPeriod being @Embeddable public class AccessPeriod { public Date startDate; public Date endDate; } If you insert in the map an AccessPeriod with both startDate and endDate set to null and persist the TestEntity, an entry is inserted in the auxiliary table, but when getting the TestEntity back, the map is empty. You get the same problem with a mapping file. This used to work in Hibernate 2.1--I found this out while porting some code to 3.3. See the attached example. You'll need to include Hibernate and h2 (com.h2database:h2 1.0.20061217) on your classpath to run it with the given jdbc.properties, but feel free to change it. -- 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-3318) Allow omitting varchar limit by default in PostgreSQL

by Luke Maurer (JIRA)

Allow omitting varchar limit by default in PostgreSQL ----------------------------------------------------- Key: HHH-3318 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3318 Project: Hibernate3 Issue Type: New Feature Components: core Environment: Hibernate 3.2.6, PostgreSQL 8.3.1 Reporter: Luke Maurer Priority: Minor Essentially, what I'd like is for a String without a given maximum length be mapped as a varchar or text rather than a varchar(255) as is now the case. The maximum doesn't do anything to improve performance or storage efficiency in PostgreSQL, so varchar(255) merely imposes an arbitrary constraint. It would be more idiomatic to use varchar where no limit is given, leaving varchar(n) for cases where the length is limited as a business rule rather than an implementation detail. (Naturally, one can always use @Lob where it's actually *important* that the column be a varchar or text. So this is definitely minor.) -- 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-620) Archetype does not deploy on JBoss Nexus repository due to missing pom fields

by Hardy Ferentschik (JIRA)

Archetype does not deploy on JBoss Nexus repository due to missing pom fields ----------------------------------------------------------------------------- Key: HSEARCH-620 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-620 Project: Hibernate Search Issue Type: Bug Components: build Affects Versions: 3.3.0.Beta3 Reporter: Hardy Ferentschik Fix For: 3.3.0.CR1 The quickstart archetype does not deploy on the Nexus server, because the test pom is missing several project information fields. For the purpose of the archetype this is not a problem, but it seems that Nexus is configured to verify certain pom fields. Using the current configuration I was not able to close the staging repository (see screenshot). As a solution we can add dummy fields for the required nodes. We should also talk to Paul - do this rules always makes sense? -- 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-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

[Hibernate-JIRA] Created: (HHH-3051) NPE while query.list on a Native SQL, using L2 cache

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.
