[Hibernate-JIRA] Created: (METAGEN-53) Remove dependency of JPA API classes to simplify setup

by Max Rydahl Andersen (JIRA)

Remove dependency of JPA API classes to simplify setup ------------------------------------------------------ Key: METAGEN-53 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-53 Project: Hibernate Metamodel Generator Issue Type: New Feature Components: processor Reporter: Max Rydahl Andersen Assignee: Hardy Ferentschik Even though the annotation processor is dependent on knowing the name of JPA API classes it shouldn't actually require access to the concrete classes. Removing this would make it one less dependency to have to configure/setup for annotation processor path. -- 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-52) Remove dependency to JPA jar/classes

by Hardy Ferentschik (JIRA)

Remove dependency to JPA jar/classes ------------------------------------ Key: METAGEN-52 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-52 Project: Hibernate Metamodel Generator Issue Type: Improvement Components: processor Affects Versions: 1.1.1.Final Reporter: Hardy Ferentschik Assignee: Hardy Ferentschik Fix For: 1.x It should be possible to remove all dependencies to JPA classes in the annotation processor. The advantage would be that when configuring the processor one does not have to specify a processor classpath. On the other hand, when using the processor you will always need a JPA jar anyways since otherwise your code won't compile. So the only benefit is a slightly "easier" configuration of the processor.

[Hibernate-JIRA] Created: (HHH-3383) QueryKey is storing references to entities instead of identifiers

by Manuel Dominguez Sarmiento (JIRA)

QueryKey is storing references to entities instead of identifiers ----------------------------------------------------------------- Key: HHH-3383 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3383 Project: Hibernate3 Issue Type: Improvement Components: caching (L2) Affects Versions: 3.3.0.CR1 Environment: ehcache 1.5.0b2 Reporter: Manuel Dominguez Sarmiento Context: query caching Hibernate is storing full entity references when building QueryKeys and the query has restrictions which reference entities. This happens either with Criteria or HQL queries. Although this is not incorrect, when the referenced entities reference in turn "heavy" object graphs, this causes a very significant memory usage increase, since references to detached entities will remain in the cache. This is even more evident when using disk persistence with ehcache, since the full object graphs are serialized to disk. This could be easily improved (correct me if I'm wrong) by storing ONLY entity identifiers in the QueryKey instead of full entities, since all the query really needs is the identifier property. The memory usage would decrease dramatically. So far the workaround we've found is explicitly using restrictions that reference identifiers instead of properties in HQL queries, however this is not particularly elegant, and still leaves open the issue with Criteria queries. The same cannot be done without criteria.createCriteria() which generates an unnecessary join in most cases. -- 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-60) Embedded class implementing List interface leads to missing identifier

by Jan Stolze (JIRA)

Embedded class implementing List interface leads to missing identifier ---------------------------------------------------------------------- Key: METAGEN-60 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-60 Project: Hibernate Metamodel Generator Issue Type: Bug Components: processor Affects Versions: 1.1.1.Final Environment: Hibernate 3.6.1 final Reporter: Jan Stolze Assignee: Hardy Ferentschik Attachments: ListOfString2.java, ListOfString2_.java I have an Embedded class which implements the java.util.List interface when running the annotation processor for the JPA meta model it fails with the message Note: Determining access type for ListOfString2 [javac] ListOfString2_.java:9: <identifier> expected [javac] public static volatile SingularAttribute<ListOfString2, String> ; when looking into the generated class the message makes sense because the identifier is indeed missing, question is how is that possible.

[Hibernate-JIRA] Created: (METAGEN-58) Subsequent processing rounds are trying to reprocess Entities that are already processed, this causes an error.

by Viet Trinh (JIRA)

Subsequent processing rounds are trying to reprocess Entities that are already processed, this causes an error. --------------------------------------------------------------------------------------------------------------- Key: METAGEN-58 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-58 Project: Hibernate Metamodel Generator Issue Type: Bug Components: processor Affects Versions: 1.1.1.Final Environment: jdk1.6.0_23, Eclipse 3.6, Maven 2, Hibernate version 3.6.1.Final, MS SQL 2005. Reporter: Viet Trinh Assignee: Hardy Ferentschik Priority: Minor I have an entity named "Car" and another processor that creates another entity name "CarAudit". After the first round, the class "Car_" and class "CarAudit" are created, therefore causing a subsequent round of processing since "CarAudit" is marked with @Entity. However, the second round fails with the following error: "diagnostic error: Problem with Filer: Attempt to recreate a file for type com.example.Car_" This is due to not clearing the "metaEntities" list from the context object after every round. Each processing round will use the same processor and context object and try to create all of the meta entries listed in the context during each round. My proposed solution is to clear the metaEntities list from the context object after each round of processing. Sorry, I do not have a test case for this right now. -- 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-50) Suppress Warnings

by Stephan Bublava (JIRA)

Suppress Warnings ----------------- Key: METAGEN-50 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-50 Project: Hibernate Metamodel Generator Issue Type: Improvement Components: processor Affects Versions: 1.1.1.Final Reporter: Stephan Bublava Assignee: Hardy Ferentschik Priority: Minor Please consider adding a @SuppressWarnings("all") annotation to the generated classes. Warnings in generated code are not helpful. In my case the warnings (driven by IDE settings) are caused by: 1) Entities marked as @Deprecated. 2) A custom Hibernate user type that maps a numeric SQL type into an EnumSet<T>. The generated SingularAttribute does not preserve the type of the set. -- 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-56) Missing Singular attribute in import when merging attributes

by Martijn Blankestijn (JIRA)

Missing Singular attribute in import when merging attributes ------------------------------------------------------------ Key: METAGEN-56 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-56 Project: Hibernate Metamodel Generator Issue Type: Bug Components: processor Affects Versions: 1.1.1.Final Environment: maven 3.0.2 Java: java version "1.6.0_22", Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Uname: Linux xxx 2.6.32-28-generic-pae #55-Ubuntu SMP Mon Jan 10 22:34:08 UTC 2011 i686 GNU/Linux Reporter: Martijn Blankestijn Assignee: Hardy Ferentschik Attachments: 0001-Missing-SingularAttribute-import-with-mixed-xml-and-.patch, surefire-reports.tar.gz I have failing testcases due to a missing import in the Generated ZeroCoordinates_.java. My analysis: The import "import javax.persistence.metamodel.SingularAttribute;" is not added to the file ZeroCoordinates_.java and will not compile due to this missing dependency. It is a mixed configuration: so in the class JPAMetaModelEntityProcessor (line 237) the call is made to metaEntity.mergeInMembers( alreadyExistingMetaEntity.getMembers() ); This basically means that the attributes of the already existing XML MetaEntity are placed in the attributesMap of the AnnotationMetaEntity. public void mergeInMembers(Collection<MetaAttribute> attributes) { for ( MetaAttribute attribute : attributes ) { members.put( attribute.getPropertyName(), attribute ); } } This means that the AnnotationEmbeddable has a Context, but the members (the merged in Xml-attributes) have a different context. (Do not understand why there are two contexts, can you enlighten me?) In the ClassWriter line 107 for ( MetaAttribute metaMember : members ) { pw.println( " " + metaMember.getDeclarationString() ); } the declaration string is printed. As the attributes are XMLMetaAttribute, their implementation of the getDeclarationString is return "public static volatile " + hostingEntity.importType( getMetaType() ) + "<" + hostingEntity.importType( hostingEntity.getQualifiedName() ) + ", " + hostingEntity.importType( getTypeDeclaration() ) + "> " + getPropertyName() + ";"; The hosting entity of the attribute is still the XmlMetaEmbeddable and when the importType is added, it is added to the wrong context (the context of the XMLMetaEmbeddable and NOT the AnnotationMetaEmbeddable). Possible solution is to change the parent or create a new merged attribute (not ugly like I do below ;-)) MetaAttribute mergedAttribute = new XmlMetaSingleAttribute(this, attribute.getPropertyName(), attribute.getMetaType()); members.put( attribute.getPropertyName(), mergedAttribute ); This resolves the problem with the missing import, but if it is better to have a single context for both annotation and xml elements this might be a cleaner solution. Attached is the 'ugly' solution, but this leaves two failing testcases: testAccessTypeForXmlConfiguredEmbeddables(org.hibernate.jpamodelgen.test.mixedmode.MixedConfigurationTest) testMixedConfiguration(org.hibernate.jpamodelgen.test.mixedmode.MixedConfigurationTest) The testMixedConfiguration could be a problem that the supplied solution is not yet the definitive answer ;-(: ======================================================= Types do not match: Wrong meta model type expected:<class org.hibernate.jpamodelgen.test.mixedmode.RentalCompany> but was:<interface javax.persistence.metamodel.SingularAttribute> org.testng.Assert.fail(Assert.java:84) at org.testng.Assert.failNotEquals(Assert.java:438) at org.testng.Assert.assertEquals(Assert.java:108) at org.hibernate.jpamodelgen.test.util.TestUtil.assertAttributeTypeInMetaModelFor(TestUtil.java:176) at org.hibernate.jpamodelgen.test.mixedmode.MixedConfigurationTest.testMixedConfiguration(MixedConfigurationTest.java:68) 30 lines not shown ======================================================= The testAccessTypeForXmlConfiguredEmbbedables seems unreleated: assertAbsenceOfFieldInMetamodelFor( ZeroCoordinates.class, "longitude", "Field access should be used, but ZeroCoordinates does not define fields" ); assertAbsenceOfFieldInMetamodelFor( ZeroCoordinates.class, "latitude", "Field access should be used, but ZeroCoordinates does not define fields" ); as I am not completely sure that the asserts are correct. The access type of embeddables dependends on the enclosing entity, so ain't it true that the field AND properties should be generated?
