[Hibernate-JIRA] Created: (HHH-6125) Hibernate Criteria.setLockMode have unexpected behaviour when used in conjunction with MySQL

by Eric Poitras (JIRA)

Hibernate Criteria.setLockMode have unexpected behaviour when used in conjunction with MySQL -------------------------------------------------------------------------------------------- Key: HHH-6125 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6125 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.2 Environment: Hibernate 3.6.2, MySql 5.1 Reporter: Eric Poitras Priority: Minor Attachments: TestHibernate.java You expect hibernate to issue a select ... for update when issuing a Criteria of this form: // This fails Criteria c = s.createCriteria(SampleEntity.class); c.setLockMode( LockMode.PESSIMISTIC_WRITE ); SampleEntity e = (SampleEntity) c.uniqueResult(); But the MySQL dialect class simply ignore the lock mode per alias since MySQL does not support a per-table locking strategy. However, in the previous case, it should issue a for update since we access ALL query tables in update. Also, since pessimistic lock may be critical for some process synchronization, it should AT LEAST not silently fail. -- 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: (BVAL-197) validation of a persisted map

by tho gau (JIRA)

validation of a persisted map ----------------------------- Key: BVAL-197 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-197 Project: Bean Validation Issue Type: Bug Environment: hibernate-core 3.5.0-Beta-3 Validator 4.0.1.GA MySQL 5.1 Reporter: tho gau Attachments: mapValidation.zip Hi, I am trying to validate an entity that holds a Map<K, V> of other persisted entities (just checking wether the map holds some predefined values). I can validate it "by hand" using validator.validate() and my map is correctly filled at validation time However when validation framework is called by persistence callbacks, my map is always empty... I am using Validator 4.0.1.GA and hibernate-core 3.5.0-Beta-2 I tryed to pinpoint the problem and it seems that the map is not touched in the following method of AbstractType during the merge : {code} public Object replace( Object original, Object target, SessionImplementor session, Object owner, Map copyCache, ForeignKeyDirection foreignKeyDirection) throws HibernateException { boolean include; if ( isAssociationType() ) { AssociationType atype = (AssociationType) this; include = atype.getForeignKeyDirection()==foreignKeyDirection; } else { include = ForeignKeyDirection.FOREIGN_KEY_FROM_PARENT==foreignKeyDirection; } return include ? replace(original, target, session, owner, copyCache) : target; } {code} -- 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-5419) COUNT operator with composite primary key and JPA 2.0 Criteria API produces bad sql

COUNT operator with composite primary key and JPA 2.0 Criteria API produces bad sql ----------------------------------------------------------------------------------- Key: HHH-5419 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5419 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.6.0.Beta1, 3.5.4, 3.5.3, 3.5.2, 3.5.1 Environment: hibernate-entitymanager 3.6.0.Beta1, glassfish 3.0.1, linux ubuntu 10.04, MS SQL Server 2008 Reporter: Fabio Braga de Oliveira Attachments: hibernate-count-bug.zip Hibernate produces a invalid SQL if anyone use the count() operator with the JPA 2.0 Criteria API.

[Hibernate-JIRA] Created: (HHH-5927) Performance risk: Suboptimal synchronization in org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan

by Strong Liu (JIRA)

Performance risk: Suboptimal synchronization in org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan --------------------------------------------------------------------------------------------------------- Key: HHH-5927 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5927 Project: Hibernate Core Issue Type: Improvement Components: core Reporter: Strong Liu Attachments: hotspot.png with Order Demo (real-life simulation attempt test app) I have noticed that there is thread contention on createNamesQuery() which sounds suspicious. After investigation it boils down to org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan. It serves as a cache (internal, not replacable) for queries using LRU algorithm (supplied from Apache utils). Generally speaking, blocking threads in any sort of caches indicates a problem. From about 2000 calls, 700 got blocked (which is also not nice for context switching). I guess, one of the problems is that there is exclusive synchronization in get method: public synchronized Object get(Object key) {...} which could be replaced by a more granular read-write lock. org/hibernate/engine/query/QueryPlanCache.java org/hibernate/util/SoftLimitMRUCache.java -- 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-640) use property names defined in CompositeUserType as default column names

by Michael Newcomb (JIRA)

use property names defined in CompositeUserType as default column names ----------------------------------------------------------------------- Key: ANN-640 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-640 Project: Hibernate Annotations Issue Type: New Feature Affects Versions: 3.3.0.ga Reporter: Michael Newcomb Priority: Minor Consider: public class LongitudeLatitude { protected double longitude; protected double latitude; } public class LongitudeLatitudeCompositeUserType implements CompositeUserType { public String[] getPropertyNames() { return new String[] { "longitude", "latitude" }; } public Type[] getPropertyTypes() { return new Type[] { Hibernate.DOUBLE, Hibernate.DOUBLE }; } ... } @Entity public class Test { @Basic(optional = false) @Type(type = "foo.bar.LongitudeLatitudeCompositeUserType") @Columns(columns = { @Column(name = "location_longitude"), @Column(name = "location_latitude") }) protected LongitudeLatitude location; } Why does the developer need to specify each column? I'd really rather let the CompositeUserType take care of that for me. Now, I have to tie the @Columns to the # of properties in my CompositeUserType AND the order in which they are defined? This seems to defeat the purpose of having a class (CompositeUserType) to tell Hibernate how to store it. Couldn't Hibernate prepend the property name 'location' and '_' to the front of each property name in the CompositeUserType? Perhaps (more than likely) I'm doing something wrong, but I get a failure if I do not specify the columns.
