[Hibernate-JIRA] Created: (HSEARCH-340) ScrollableResults exploits batch loading for backwards and random order scrolling

by Sanne Grinovero (JIRA)

ScrollableResults exploits batch loading for backwards and random order scrolling --------------------------------------------------------------------------------- Key: HSEARCH-340 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-340 Project: Hibernate Search Issue Type: Improvement Components: query Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 3.1.1 ScrollableResults is trying to load by batches only in forward direction, even if this is the most common use it is trivial to make it a bit smarter. This also improves a "somehow random" loading order, as far as the requested entities are not too far away from each other, or if a "random intelligent" pattern will result in loading all results as end result (and enough memory is available so that caches were not emptied). -- 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] Commented: (ANN-391) SecondaryTables not recognized when using JOINED inheritance

[Hibernate-JIRA] Created: (HHH-3642) EJB3 inheritance strategy TABLE_PER_CLASS does not work on HSQLDB

by Wolfgang Knauf (JIRA)

EJB3 inheritance strategy TABLE_PER_CLASS does not work on HSQLDB ----------------------------------------------------------------- Key: HHH-3642 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3642 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.3.1 Environment: JBoss 5.0GA, Java 1.6, Hypersonic 1.8.0.8 Reporter: Wolfgang Knauf Attachments: InheritanceTablePerClass.ear I use an EJB3 entity bean with inheritance strategy "TABLE_PER_CLASS": @Entity @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) public abstract class Base implements Serializable { ... When loading a list of base classes, all subclass fields are null. The union subclause in the query does not work on HSQLDB. Attached is a full EJB sample, runnable on JBoss 4.2/5.0 (project export of Eclipse 3.4/WebTools 3.0 with sources). After deploying, it can be tested by browsing to http://localhost:8080/InheritanceTablePerClassWeb/ See this output: ... Loading ALL Item: Child 1, child field 1: null Item: Child 2, child field 2: null Item: Child 3, child field 3: Field of Child3 ... Here, all childs are loaded. The fields of type "Child1" and "Child2" are null, fields of type "Child3" are filled. This is probably a duplicate of http://opensource.atlassian.com/projects/hibernate/browse/HHH-2920 The described workaround to change all NULL expressions to "cast (null as VARCHAR)" results in a working query, but I see no chance to pre-configure this query in the entity manager. I created another bug, because the impact is different (it breaks a feature of EJB3), and so I consider severity to be higher. -- 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-41) Support BeanInfo implementation to receive property names

by Emmanuel Bernard (JIRA)

Support BeanInfo implementation to receive property names --------------------------------------------------------- Key: BVAL-41 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-41 Project: Bean Validation Issue Type: Improvement Components: spec-general Reporter: Emmanuel Bernard Michael - Why section 3.1.2 requires properties to follow the JavaBeans naming convention? In many non-English speaking countries (and projects with ridiculous managers/code standards), other prefixes are used and proper BeanInfo implementations are supplied. Although it is not pretty at all, since they are following the JavaBean spec, I don't think Bean Validation shouldn't work out-of-the-box for them; Emmanuel I reused the Java Persistence wording actually and I explicitly reference the Introspector class. Do people think we should be more cautious here? Speaking for France, I've never seen a project bothering about get/is/set and BeanInfo. People happily used frenglish: getCafeAuLait() Actually I've never seen anybody from the server side bothering about BeanInfos ;) Michael I've got an interesting case for that one: in some JVM languages, another standard is used to represent properties. Let's take, for instance, Scala. In Scala, one could write a bean like: @BeanInfo class Person(var id : Long, var name : String, var surname : String) Scala already maps vars as properties creating a private var, a public getter method named like the var and a setter like var_=. Something like: private var _id : Long def id = _id def id_=(newId: Long) = _id = newId that would translate to Java methods id and id_$eq (since = cannot be used in method names). So, when one use @BeanInfo, a proper BeanInfo subclass is generated by the compiler providing that mapping. Given how popular JVM languages are getting, not following a spec in another one and causing property support in those languages to fail to work doesn't seem nice. BTW, please let the JPA EG know about his as well. -- 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-3831) composite-id + generator +foreign

by Sandeep Vaid (JIRA)

composite-id + generator +foreign --------------------------------- Key: HHH-3831 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3831 Project: Hibernate Core Issue Type: Bug Components: core Reporter: Sandeep Vaid Attachments: ProductAndProductBasicDetails.txt, ProductAndProductBasicError.txt I have 2 classes viz. Product and ProductBasic which has one-to-one relationship. Product is mapped to a table PRODUCT which has PRODUCTID as PK. ProductBasic is mapped to a table PRODUCTBASIC which has PRODUCTID,USETYPE and STARTTTIMESTAMP as composite key. Also PRODUCTID is the foreign key referencing PRODUCT table... When i am saving Product (with cascade for ProductBasic): For Product, it's taking persister.identifierType as org.hibernate.type.CustomType For ProductBasic, it's taking persister.identifierType as org.hibernate.type.ComponentType Assume productId='1' When i call session.save(product), a) For Product: it tries to find hashmap of id=1 using org.hibernate.type.StringType.getHashCode() which comes out to be 49 (ASCII).. b) For ProductBasic: it tries to find hashmap of id=1 using org.hibernate.type.ComponentType.getHashCode() and throws exception: org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of com.tietoenator.lis.db.impl.product.bo.CompProductBasicBO.useType Does it treating ProductBasic as component because it's productId value depends upon Product.productId? Even if it treats ProductBasic as component, why it is not fetching the proper hashCode() and throwing exception? -- 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] Créée: (HHH-2060) To be able to use <generator> with <composite-id>

by Xavier Brénuchon (JIRA)

To be able to use <generator> with <composite-id> ------------------------------------------------- Key: HHH-2060 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2060 Project: Hibernate3 Type: Improvement Versions: 3.2.0.cr4 Environment: Hibernate 3.x Reporter: Xavier Brénuchon Hello, This is the continuation of HB-389 We develop an application which has very strong need for performance with several tens of million recordings. Partitioning is a need. So for that, I use <composite-id>. But my primary key is not a natural key, but a real technical key : - column of partitioning for optimization of the data base - column of technical id So I need to have a generator, for exemple : <composite-id name="id" class="IdPartition"> <key-property name="org" type="string" column="ORG"/> <key-property name="id" type="long" column="ID"/> <generator class="fr.test.xavier.IdPartitionGenerator"> <param name="table">TAB_SEQ</param> <param name="column">LAST</param> </generator> </composite-id> The good news is that Hibernate can use that (HB-389). In fact, it is enough to modify the DTD to authorize <generator> in <composite-id> and it is all. The current code of Hibernate manages it very well. Is it possible that Hibernate is enriched by this functionality? -- 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
