[Hibernate-JIRA] Created: (METAGEN-72) Generate attributes for @Transient columns

by Adriano dos Santos Fernandes (JIRA)

Generate attributes for @Transient columns ------------------------------------------ Key: METAGEN-72 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-72 Project: Hibernate Metamodel Generator Issue Type: Improvement Components: processor Reporter: Adriano dos Santos Fernandes Assignee: Hardy Ferentschik Hibernate doesn't not generate metadata attributes for @Transient columns. They may be not interesting for criteria queries, but attributes may be used for general usage of entities across the application, for example, to construct screens. Please at least add an option to generate them. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2052) org.hibernate.pretty.MessageHelper.collectionInfoString tries to cast wrong object to String, causes ClassCastException

by Tree 'Huggy Bear' Hugger (JIRA)

org.hibernate.pretty.MessageHelper.collectionInfoString tries to cast wrong object to String, causes ClassCastException ----------------------------------------------------------------------------------------------------------------------- Key: HHH-2052 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2052 Project: Hibernate3 Type: Bug Reporter: Tree 'Huggy Bear' Hugger Attachments: bugtest.zip Debug level logging attempted by MessageHelper falls over when constructing a loggable string for a mapped collection on the main entity. Following the code in the stacktrace, I can see that MessageHelper expects the parent key for the collection relationship to be the primary key, but it is mapped to another field of a different type via a property-ref. Hence the ClassCastException below. The work around is to set logging to INFO or higher. I have also attached a pared-down zip with the maven 2 project containing the mappings and the unit test which fails. The following JIRA issue may be the same thing: http://opensource.atlassian.com/projects/hibernate/browse/ANN-298 The following messages on the Hib forum demonstrate other interest in this issue: http://forum.hibernate.org/viewtopic.php?t=949913 http://forum.hibernate.org/viewtopic.php?t=956778 http://forum.hibernate.org/viewtopic.php?t=962471 java.lang.ClassCastException: com.nomadsoft.cortex.domain.country.basic.BasicCountry at org.hibernate.type.StringType.toString(StringType.java:44) at org.hibernate.type.NullableType.toLoggableString(NullableType.java:168) at org.hibernate.pretty.MessageHelper.collectionInfoString(MessageHelper.java:284) at org.hibernate.loader.Loader.readCollectionElement(Loader.java:972) at org.hibernate.loader.Loader.readCollectionElements(Loader.java:635) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:580) at org.hibernate.loader.Loader.doQuery(Loader.java:689) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.loadEntity(Loader.java:1785) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:47) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:41) at org.hibernate.persister.entity.AbstractEntityPersister.load(AbstractEntityPersister.java:2730) at org.hibernate.event.def.DefaultLoadEventListener.loadFromDatasource(DefaultLoadEventListener.java:365) at org.hibernate.event.def.DefaultLoadEventListener.doLoad(DefaultLoadEventListener.java:346) at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:123) at org.hibernate.event.def.DefaultLoadEventListener.proxyOrLoad(DefaultLoadEventListener.java:177) at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:87) at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:862) at org.hibernate.impl.SessionImpl.get(SessionImpl.java:799) at org.hibernate.impl.SessionImpl.get(SessionImpl.java:792) at org.springframework.orm.hibernate3.HibernateTemplate$1.doInHibernate(HibernateTemplate.java:452) at org.springframework.orm.hibernate3.HibernateTemplate.execute(HibernateTemplate.java:366) at org.springframework.orm.hibernate3.HibernateTemplate.get(HibernateTemplate.java:446) at org.springframework.orm.hibernate3.HibernateTemplate.get(HibernateTemplate.java:440) at com.nomadsoft.cortex.infrastructure.hibernate.HibernateCountryRepository.getById(HibernateCountryRepository.java:26) at com.nomadsoft.cortex.domain.country.basic.BasicCountryService.getCountry(BasicCountryService.java:34) etc etc -- 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-2515) Remove all documentation about HAR, it is deprecated

by Christian Bauer (JIRA)

Remove all documentation about HAR, it is deprecated ---------------------------------------------------- Key: HHH-2515 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2515 Project: Hibernate3 Type: Improvement Components: documentation Reporter: Christian Bauer Priority: Critical Clearly not one of the best ideas we ever had is the HAR deployment. It should now be considered deprecated (superseded by the EJB3/JPA deployment model) and any documentation about it should be removed. This includes JBoss AS user guides, wiki pages, etc. If you have any objects and think that HAR is a fantastic thing, raise them here. -- 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: (METAGEN-76) SingularAttribute generated for hashCode method in @Embeddable

by Hrotkó Gábor (JIRA)

SingularAttribute generated for hashCode method in @Embeddable -------------------------------------------------------------- Key: METAGEN-76 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-76 Project: Hibernate Metamodel Generator Issue Type: Bug Components: processor Affects Versions: 1.1.1.Final Environment: hibernate-jpamodelgen 1.1.1.Final, postgresql 8 Reporter: Hrotkó Gábor Assignee: Hardy Ferentschik I got a class composite id class for a table with @Embeddable. It has two properties, and the equals and the hashCode methods. When hibernate-jpamodelgen 1.1.1.Final generates the metaclasses, I got a SingularAttribute with the name "hashCode" generated. But hashCode is not a property in the entity. entity: /** by hbm2java */ @Embeddable public class MyTableId implements java.io.Serializable { private String id; private Integer memberId; public MyTableId() { } public MyTableId(String id, Integer memberId) { this.id = id; this.memberId = memberId; } @Column(name="id") public String getId() { return this.id; } public void setId(String id) { this.id = id; } @Column(name="member_id") public Integer getMemberId() { return this.memberId; } public void setMemberId(Integer memberId) { this.memberId = memberId; } public boolean equals(Object other) { if ( (this == other ) ) return true; if ( (other == null ) ) return false; if ( !(other instanceof MyTableId) ) return false; MyTableId castOther = ( MyTableId ) other; return ( (this.getId()==castOther.getId()) || ( this.getId()!=null && castOther.getId()!=null && this.getId().equals(castOther.getId()) ) ) && ( (this.getMemberId()==castOther.getMemberId()) || ( this.getMemberId()!=null && castOther.getMemberId()!=null && this.getMemberId().equals(castOther.get MemberId()) ) ); } public int hashCode() { int result = 17; result = 37 * result + ( getId() == null ? 0 : this.getId().hashCode() ); result = 37 * result + ( getMemberId() == null ? 0 : this.getMemberId().hashCode() ); return result; } } metaclass: @StaticMetamodel(MyTableId.class) public abstract class MyTableId_ { public static volatile SingularAttribute<MyTableId, String> id; public static volatile SingularAttribute<MyTableId, Integer> hashCode; public static volatile SingularAttribute<MyTableId, Integer> memberId; } -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-4550) query cache: Attention with configuring Update Timestamps Cache region: expired entries cause wrong result sets!

by Guenther Demetz (JIRA)

query cache: Attention with configuring Update Timestamps Cache region: expired entries cause wrong result sets! ---------------------------------------------------------------------------------------------------------------- Key: HHH-4550 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4550 Project: Hibernate Core Issue Type: Improvement Components: caching (L2) Affects Versions: 3.3.2 Environment: 3.3.2 GA Reporter: Guenther Demetz Priority: Trivial Attachments: TestCaseQuryCache.jar When using hibernate's query cache (hibernate.cache.use_query_cache), then it's of fundamental importance to configure the Update Timestamps cache region in a way that his entries survive longer than the cached result sets in the Query cache region. Otherwise queries could return wrong (obsolete) result sets (See attached testcase). This is because the current UpdateTimestampsCache#isUpToDate implementation considers a result-set also as up-to-date, if there are no update-timestamps cached for the interested spaces (tables) at all. It if therefore important to notice that: 1- The Update-Timestamps-Cache-Region elements max-size should be configured higher than the number of tables you have on the db-schema, in manner that he can remember/hold the last update-timestamp for each table. 2- If you use any other eviction policy in the Update-Timestamps-Cache-Region, then you must assure that cached result sets in the Query-cache-region are evicted before relevant update-timestamps are going to be evicted. This fact should be clearly documented somewhere.
