[Hibernate-JIRA] Created: (HSHARDS-57) For a better "virtual shards" support!

by Colbert Philippe (JIRA)

For a better "virtual shards" support! -------------------------------------- Key: HSHARDS-57 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSHARDS-57 Project: Hibernate Shards Issue Type: Improvement Affects Versions: 3.0.0.Beta2 Environment: Windows XP Reporter: Colbert Philippe Assignee: Max Ross The current implementation of virtual shards leaves a lot to be desired when used in big corporate applications. A better way to model shards, is to identify a virtual shard by a pairing of "some name" + "an index" (example: Clients, 11). The name plays a role similar to namespaces. The index is always zero based and valid only within the namespace. There can be many shard namespaces with unique names. A configuration file (possibly XML) will map each virtual shard to a single physical shard. It's a simple mapping strategy. The mapping can allow overlaps of virtual shards into a single physical shard. This type of naming can make things more clear and easier to manage on the long-run. The big advantage to virtual shards over physical shards is that virtual shards can be easily persisted to file or database and retrieved again and still remain valid. Any change to the shard structure is fully controlled by the shard configuration file, without modifications to the persisted representation of the shard. This way the code can evolve separately from the physical shard architecture. With this kind of virtual shard, top-of-tree classes will map to a single shard namespace. The object will reside in any of the virtual shard indexes associated with the shard namespace. The resolution strategy becomes very simple because the set of shard indexes will be returned. -- 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-3464) SimpleExpression.ignoreCase uses SQL server lowercase function for left part and JAVA lowercase function for right part of expression

by Vitaliy Tymchyshyn (JIRA)

SimpleExpression.ignoreCase uses SQL server lowercase function for left part and JAVA lowercase function for right part of expression ------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3464 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3464 Project: Hibernate3 Issue Type: Bug Components: query-criteria Affects Versions: 3.2.6 Environment: tried with PostgreSQL Reporter: Vitaliy Tymchyshyn Priority: Minor When using SimpleExpression.ignoreCase (e.g. Restrictions.eq().ignoreCase, hibernate makes 'lower(field)=?' SQL expression, passing lowercased strings to '?' parameter. This may produce unpredictable results depending on Database server lower implementation and current JAVA locale (see JDK javadoc). For example, I've tried with '\u0130' character as in JDK JavaDoc. Postgresql produces: unhappy=> select lower('İ'); lower ------- i̇ (1 row) unhappy=> select char_length(lower('İ')); char_length ------------- 2 (1 row) While Java with default locale produces single-character 'i̇'. Of course the restriction will not work - it can not find 'İ' in database. I'd recommend to use 'lower(field)=lower(?)' to use same lower casing function for both parts of expression. -- 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: (JPA-15) Criteria API based on MapKeyColumn is not working

by Edwin Dalorzo (JIRA)

Criteria API based on MapKeyColumn is not working ------------------------------------------------- Key: JPA-15 URL: http://opensource.atlassian.com/projects/hibernate/browse/JPA-15 Project: Java Persistence API Issue Type: Bug Environment: Hibernate 3.6.1 MySQL 5.0 Reporter: Edwin Dalorzo Attachments: log.txt, src.zip I defined an Employee entity having a map of phone numbers, where the key is the type of phone (home, office, mobile) and the value is the phone number as a String. @ElementCollection(fetch=FetchType.LAZY) @CollectionTable(name="emp_phone") @MapKeyColumn(name="phone_type") @Column(name="phone_num") private Map<String, String> phoneNumbers; Then I tried to write a Criteria API query using a map join, like this: CriteriaBuilder builder = entityManager.getCriteriaBuilder(); CriteriaQuery<Employee> criteria = builder.createQuery(Employee.class); Root<Employee> employeeRoot = criteria.from(Employee.class); criteria.select(employeeRoot); MapJoin<Employee, String, String> phoneRoot = employeeRoot.joinMap("phoneNumbers"); criteria.where(builder.equal(phoneRoot.key(), "HOME")); System.out.println(entityManager.createQuery(criteria).getResultList()); You get an NullPointerException java.lang.NullPointerException at org.hibernate.ejb.criteria.path.AbstractPathImpl.prepareAlias(AbstractPathImpl.java:246) at org.hibernate.ejb.criteria.path.AbstractPathImpl.render(AbstractPathImpl.java:253) at org.hibernate.ejb.criteria.predicate.ComparisonPredicate.render(ComparisonPredicate.java:173) at org.hibernate.ejb.criteria.QueryStructure.render(QueryStructure.java:258) at org.hibernate.ejb.criteria.CriteriaQueryImpl.render(CriteriaQueryImpl.java:340) at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:223) at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:441) at com.dalorzo.Main.main(Main.java:57) Exception in thread "main" java.lang.RuntimeException: java.lang.NullPointerException at com.dalorzo.Main.main(Main.java:64) Caused by: java.lang.NullPointerException at org.hibernate.ejb.criteria.path.AbstractPathImpl.prepareAlias(AbstractPathImpl.java:246) at org.hibernate.ejb.criteria.path.AbstractPathImpl.render(AbstractPathImpl.java:253) at org.hibernate.ejb.criteria.predicate.ComparisonPredicate.render(ComparisonPredicate.java:173) at org.hibernate.ejb.criteria.QueryStructure.render(QueryStructure.java:258) at org.hibernate.ejb.criteria.CriteriaQueryImpl.render(CriteriaQueryImpl.java:340) at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:223) at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:441) at com.dalorzo.Main.main(Main.java:57) If you change the query to filter on value instead of key, it works just fine criteria.where(builder.equal(phoneRoot.value(), "88750372")); I have attached a log with exceptions as well as the Employee entity and the Main class containing a main method. Also, the code in question runs perfectly fine in EclipseLink. -- 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-6608) @JoinColumns doesn't work inside an @Embedded member

by Joeri Hendrickx (JIRA)

@JoinColumns doesn't work inside an @Embedded member ---------------------------------------------------- Key: HHH-6608 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6608 Project: Hibernate Core Issue Type: Bug Components: annotations, metamodel Affects Versions: 4.0.0.CR1, 3.5.6 Environment: Version 3.5.6 and up, no DB Reporter: Joeri Hendrickx Attachments: hibernate-embedded-joincolumns.zip If you use multiple joincolumns on a @ManyToOne or @OneToOne field in an @Embedded class, hibernate will fail when building its metamodel with the following exception: Exception in thread "main" org.hibernate.MappingException: property [_model_MainEntity_embeddedEntity.referencedEntity] not found on entity [model.ReferencedEntity] at org.hibernate.mapping.PersistentClass.getRecursiveProperty(PersistentClass.java:379) at org.hibernate.cfg.annotations.TableBinder.bindFk(TableBinder.java:406) at org.hibernate.cfg.ToOneFkSecondPass.doSecondPass(ToOneFkSecondPass.java:111) at org.hibernate.cfg.AnnotationConfiguration.processEndOfQueue(AnnotationConfiguration.java:541) at org.hibernate.cfg.AnnotationConfiguration.processFkSecondPassInOrder(AnnotationConfiguration.java:523) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:380) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1377) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:954) at model.Test.main(Test.java:12) Caused by: org.hibernate.MappingException: property [_model_MainEntity_embeddedEntity.referencedEntity] not found on entity [model.ReferencedEntity] at org.hibernate.mapping.PersistentClass.getRecursiveProperty(PersistentClass.java:425) at org.hibernate.mapping.PersistentClass.getRecursiveProperty(PersistentClass.java:376) ... 8 more A test case is included. Just run model. Test with the hibernate libraries in the classpath. I get the impression this is because of the dot in the generated property name. Hibernate generates a synthetic property, named after the FQN of the owning entity (with dots replaces by underscores) appended by and underscore and the name of the property. But properties inside of embedded objects are represented with a dot; when Hibernate later tries to retrieve the same property, it incorrectly interprets this dot as a delimiter, and will look for `_model_MainEntity_embeddedEntity` (in the example above) instead; which it will not find. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-7108) @TypeDef doesn't work for enums

by Michael Nascimento Santos (JIRA)

@TypeDef doesn't work for enums ------------------------------- Key: HHH-7108 URL: https://hibernate.onjira.com/browse/HHH-7108 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.1.0 Environment: hibernate-jpa-2.0-api:1.0.1-Final; hibernate-core:4.1.0.Final; hibernate-entitymanager:4.1.0.Final Reporter: Michael Nascimento Santos Priority: Critical @TypeDef is supposed to allow users to define standard types to be used for specific classes. However, due to a bug in implementation, it simply doesn't work for enums. Enums are implicitly handled by the JPA spec. However, if a @TypeDef is defined for a particular enum, it will never be picked up due to bug in org.hibernate.cfg.annotations.SimpleValueBinder . This class has a concept of a "explicitType", i.e., a type that was explicitly specified for a property. However, even if @EnumType is not used to annotate a property, method setType(XProperty,XClass) considers the property as annotated with it. Then, when fillSimpleValue() is called as part of second-pass compilation, the ternary in line 344 chooses org.hibernate.type.EnumType instead of the enum FQN, causing any @TypeDef to be ignored. This behaviour should be fixed by considering a non-annotated enum property as implicitly typed, not explicitly. Then, the resolution order should be changed to explicitType -> returnedClassName -> implicitType. This would preserve default, expected behaviour for regular enums, while allowing @TypeDef to be used for enums as well. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-2808) CLONE -Impossible to define caching for a subclass's collection in hibernate.cgf.xml

by Sebastien Blind (JIRA)

CLONE -Impossible to define caching for a subclass's collection in hibernate.cgf.xml ------------------------------------------------------------------------------------- Key: HHH-2808 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2808 Project: Hibernate3 Issue Type: Bug Components: caching (L2) Affects Versions: 3.2.5 Environment: Hibernate 3.2.5 Sybase Reporter: Sebastien Blind Basically, hibernate allows to define <cache usage="transactional"/> inside the subclass mapping, i.e. <subclass name="SubClass" extends="BaseClass" discriminator-value="xxx"> <bag name="subClassLinks" lazy="false" inverse="true" batch-size="100"> <cache usage="transactional" region="xxx"/> <key column="xxx" not-null="true"/> <one-to-many class="xxx"/> </bag> <join table="xxx"> </join> </subclass> but it's not allowed to do the same using <collection-cache collection="subClass.myCollection" region="xxx" usage="transactional"/>.
