[Hibernate-JIRA] Created: (ANN-618) @AccessType("propery") cannot be overriden by @AccessType("field")

by Dennis Fleurbaaij (JIRA)

@AccessType("propery") cannot be overriden by @AccessType("field") ------------------------------------------------------------------ Key: ANN-618 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-618 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.2.0.ga Environment: Hibernate 3.2.1, Hibernate Annotations 3.2.0, Jboss 5 embeddable beta2 Reporter: Dennis Fleurbaaij Priority: Minor Attachments: AccessTest.java, Gardenshed.java The error comes down to the fact the following code does not work (also doesn't work when the @AccessType is place on the field): [code] @AccessType("propery") public class Test() { private String test; @AccessType("field") public WeirdCollection getTest() { return new WeirdCollection( test ); } } [/code] Attachments are a class that tests this and the extended unit tests for all of this. Unfortunately both are not tested as I have no envoronment on hand here. Will probably require some work. should be placed in /hibernate-annotations-3.2.0.GA/test/org/hibernate/test/annotations/access Attached to forum thread: http://forum.hibernate.org/viewtopic.php?p=2353727#2353727 -- 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-617) NullPointerException when handling @OrderBy

NullPointerException when handling @OrderBy ------------------------------------------- Key: ANN-617 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-617 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.0.ga Environment: Hibernate Core 3.2.4.SP1; Hibernate Annotations 3.3.0 GA; Hibernate EntityManager 3.3.1 GA; Oracle OC4J; Oracle DB 10g Reporter: Jifeng Liu After I updated from Hibernate Annotations 3.2.1ga to 3.3.0ga, I get the following NullPointerException: Caused by: java.lang.NullPointerException at org.hibernate.cfg.annotations.CollectionBinder.buildOrderByClauseFromHql(CollectionBinder.java:851) at org.hibernate.cfg.annotations.CollectionBinder.bindManyToManySecondPass(CollectionBinder.java:1133) at org.hibernate.cfg.annotations.CollectionBinder.bindStarToManySecondPass(CollectionBinder.java:576) at org.hibernate.cfg.annotations.CollectionBinder$1.secondPass(CollectionBinder.java:517) at org.hibernate.cfg.CollectionSecondPass.doSecondPass(CollectionSecondPass.java:43) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1130) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:316) at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1115) at org.hibernate.ejb.Ejb3Configuration.buildMappings(Ejb3Configuration.java:1269) at org.hibernate.ejb.EventListenerConfigurator.configure(EventListenerConfigurator.java:150) at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:888) at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:416) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:138) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:114) at com.evermind.server.ejb.persistence.PersistenceUnitManagerImpl.createContainerEntityManagerFactory(PersistenceUnitManagerImpl.java:175) After I debug it, the variable 'pc' is null in the CollectionBinder.java:851 line: table = pc.getTable().getQuotedName() + "."; It seems like this bug is introduced by fix of ANN-516 '@OrderBy added to wrong table in inheritance relationship'.

[Hibernate-JIRA] Commented: (HHH-1311) Session.load is O(n) when outside a transaction

by Matt Sgarlata (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1311?page=c... ] Matt Sgarlata commented on HHH-1311: ------------------------------------ I am trying to use Hibernate to render a screen with around 9,000 data points and about 2,000 objects in the session-level cache. JProbe shows that 50.2% of the time it takes for this screen to render is up by StatefulPersistenceContext.afterTransactionCompletion(). So, half of request processing time is used to retrieve items that are already in memory and part of the cache! The only reason I said it was outside a transaction is because StatefulPersistenceContext.afterTransactionCompletion() is called as part of JDBCContext.afterNontrasnactionalQuery(boolean). > Session.load is O(n) when outside a transaction > ----------------------------------------------- > > Key: HHH-1311 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1311 > Project: Hibernate3 > Issue Type: Improvement > Components: core > Affects Versions: 3.0.5 > Reporter: Matt Sgarlata > > When retrieving objects from the session-level cache, session.load is O(n) when outside a transaction, where n = the number of objects currently contained in the session-level cache. This is because after each object is retrieved Hibernate iterates through all objects in the session and sets the lock mode to LockMode.NONE. This means reading all objects from the Hibernate session-level cache while outside a transaction is an O(n^2) operation instead of an O(n) operation. > If my understanding is correct, all objects in the session should already have that lock mode unless a different lock mode was specifically requested by the user. Thus iterating through all objects in the session is not necessary in the vast majority of cases. I think performance could be improved here by maintaining a cache of the objects in the session that are currently locked. Then performance of session.load would be O(m) where m is the number of objects which are currently locked in the session. In the vast majority of cases this would effectively make session.load a O(1) operation since objects in the session typically are not locked. > The other solution for me, of course, would be to just wrap all web requests so that I begin transactions at the start of the request and end transactions at the end of the request. However, I don't want to do that because transactions require database resources and I feel it's not necessary to incur that overhead on the read-only screens in my application. -- 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-608) NullPointerException from AnnotationConfiguration with specific order of calling addResource and addPackage when package-info.java present

by Steve Gilbert (JIRA)

NullPointerException from AnnotationConfiguration with specific order of calling addResource and addPackage when package-info.java present ------------------------------------------------------------------------------------------------------------------------------------------ Key: ANN-608 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-608 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Environment: Hibernate 3.2.3 Reporter: Steve Gilbert Attachments: Main.java, orm.xml, package-info.java There is a bug in AnnotationConfiguration that causes a NullPointerException. I have attached several files: orm.xml, Main.java, package-info.java. The problem is caused by the order of the addResource and addPackage calls in combination with having a package-info.java file with some contents. If the addPackage is called before the addResource, or if the GenericGenerator annotation in the package info file is removed, there is no problem. I cannot change the order of those calls for my production code, however, because Spring is being used to create the SessionFactory and it calls the methods in that order: resource followed by package. There appears to be a problem with initializing org.hibernate.cfg.annotations.reflection.EJB3OverridenAnnotationReader. When this call is made on line 360: annotationsMap.put( ann.annotationType(), ann ); the map is null. Inserting a creation for the map, (borrowed from elsewhere in the method) on line 359, before the "for" statement: annotationsMap = new HashMap<Class, Annotation>( annotations.length + 5 ); resolves the problem. -- 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-2725) ByteType.equals(Object, Object) wrong comparison

by Daniel Frey (JIRA)

ByteType.equals(Object, Object) wrong comparison ------------------------------------------------ Key: HHH-2725 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2725 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.4 Reporter: Daniel Frey was trying to update an object that has been altered in byte array fields. So probably I found a serious bug in ByteType.equals(Object, Object):35 ByteTypeContent xi = (ByteTypeContent) x; ByteTypeContent yi = (ByteTypeContent) x; return xi.equals(yi); Should probably read: ByteTypeContent xi = (ByteTypeContent) x; ByteTypeContent yi = (ByteTypeContent) y; // <----! return xi.equals(yi); What do you think?

[Hibernate-JIRA] Created: (HHH-2724) Update EJBQL query generating bad SQL

by Jonathan O'Connor (JIRA)

Update EJBQL query generating bad SQL ------------------------------------- Key: HHH-2724 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2724 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.4.sp1 Environment: Hibernate version: 3.2.4SP1 with 3.3.1GA EntityManager and 3.3.0GA Annotations, running on Postgresql 8.1 Reporter: Jonathan O'Connor Attachments: test.jar The generated SQL (show_sql=true): update Person set name=? where (id in (select customer1_.id from Customer customer1_ ) ) and person0_.name<>? My EJBQL query is: update Person set name = ?1 where id in (select c.id from Customer c) and name <> ?2 The generated SQL refers to an unknown table alias "person0_". A workaround is to change around the conditions in the where clause. That is: update Person set name = ?1 where name <> ?2 and id in (select c.id from Customer c) does not generate bad code. If I add a where clause to the inner select, then the problem also goes away. Finally, correct SQL is generated in the matching select. Doing a delete instead of update also causes bad code, and the workarounds are also the same: delete Person where id in (select id from Customer) and name <> 'Y' The attached jar file has two classes Person and Customer. There is also a persistence.xml in the META-INF directory. ts configured for a local postgres system. You may need to alter this file. I tested the SQL generation using Hibernate Tools plugin for Eclipse. -- 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
