[Hibernate-JIRA] Created: (HHH-3356) Support for subselect (subquery) in from clause

by Geoffrey De Smet (JIRA)

Support for subselect (subquery) in from clause ----------------------------------------------- Key: HHH-3356 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3356 Project: Hibernate3 Issue Type: New Feature Components: query-hql Reporter: Geoffrey De Smet Many databases support subselects in the from clause, for example: http://dev.mysql.com/doc/refman/5.0/en/unnamed-views.html And it's very handy. Native query's are sometimes a working workaround, but have many disadvantages, unlike HQL. Btw, I've searched through jira for over 20 minutes and didn't find an issue for this already. If there is one already, please give it a better title or link it to this issue :) -- 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-2097) LAZY property results in org.hibernate.TransientObjectException after merge

by Reto Urfer (JIRA)

LAZY property results in org.hibernate.TransientObjectException after merge --------------------------------------------------------------------------- Key: HHH-2097 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2097 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Environment: Hibernate3.2 cr4 with Annotations cr2 and EntityManager cr2, Oracle10g R2, WindowsXP Reporter: Reto Urfer Priority: Critical Attachments: BugLazyPropertyMerge.zip Entity1 has a property e2 which references Entity2. This property is defined as follows. @ManyToOne(fetch = FetchType.LAZY, optional = false) private Entity2 e2; If you have an instance e1 of Entity1 which has not initialized property e2 and you merge e1 to the EntityManager within a transaction, then you get the following exception during commit: Exception in thread "main" javax.persistence.RollbackException: Error while commiting the transaction at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:63) at com.test.Test.main(Test.java:42) Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.test.Entity1.e2 -> com.test.Entity2 at org.hibernate.engine.CascadingAction$9.noCascade(CascadingAction.java:350) at org.hibernate.engine.Cascade.cascade(Cascade.java:139) at org.hibernate.event.def.AbstractFlushingEventListener.cascadeOnFlush(AbstractFlushingEventListener.java:130) at org.hibernate.event.def.AbstractFlushingEventListener.prepareEntityFlushes(AbstractFlushingEventListener.java:121) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:65) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:53) ... 1 more I added a small Testproject to reproduce this bug. -- 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: (HBX-1042) Make DocHelper robust against failing buildSettings()

by Arnout Engelen (JIRA)

Make DocHelper robust against failing buildSettings() ----------------------------------------------------- Key: HBX-1042 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1042 Project: Hibernate Tools Issue Type: Improvement Components: hbm2doc Reporter: Arnout Engelen Attachments: dochelper.diff.txt DocHelper calls cfg.buildSettings(). to get the Dialect, default catalog name and default schema name. However, cfg.buildSettings() may fail with a HibernateException (example below). It would be nice to have DocHelper handle this more gracefully. Attached is a simple patch that does this. (background: I'd like to use the Configuration I'm getting from a Spring LocalSessionFactoryBean, which after initial creation leaves its LocalDataSourceConnectionProvider in a state that yiels a HibernateException when calling 'configure()' on it, which buildSettings() does. Because of this issue, I cannot use the DocExporter for my Spring-based hibernate configurations) -- 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: (HSEARCH-275) support new NIOFSDirectory, a multithreaded optimized FSDirectory

by Sanne Grinovero (JIRA)

support new NIOFSDirectory, a multithreaded optimized FSDirectory ----------------------------------------------------------------- Key: HSEARCH-275 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-275 Project: Hibernate Search Issue Type: Improvement Reporter: Sanne Grinovero Assignee: Sanne Grinovero # LUCENE-753: Added new Directory implementation org.apache.lucene.store.NIOFSDirectory, which uses java.nio's FileChannel to do file reads. On most non-Windows platforms, with many threads sharing a single searcher, this may yield sizable improvement to query throughput when compared to FSDirectory, which only allows a single thread to read from an open file at a time.

by Juergen Zimmermann (JIRA)

Add @Equals(property="name") ---------------------------- Key: HV-70 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-70 Project: Hibernate Validator Issue Type: New Feature Affects Versions: 3.1.0.CR2 Reporter: Juergen Zimmermann It would be nice to have something like: public class Customer implements Serializable { private String password; @Equals(property="password") // the name of the property above private String password2; ... } Such entity classes would be helpful for user interfaces e.g. inside registration pages where you want to avoid typos or ensure that a human being is registering. -- 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: (HSEARCH-115) Add a default value for indexing null value

by Julien Brulin (JIRA)

Add a default value for indexing null value ------------------------------------------- Key: HSEARCH-115 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-115 Project: Hibernate Search Issue Type: Improvement Components: mapping Reporter: Julien Brulin Hi, Null elements are not indexed by lucene then it's not easy to use a nullable property in lucene query. I have a TagTranslation entity in my model with a nullable property language. In this case null is used as default language for tag translation. Each translation may have many variations like synonyms. Because I can specified a default value for null value in the @Field annotation like this @Field(index=Index.UN_TOKENIZED, store=Store.NO, default='null'), i can't search a cat tag with a default translation like this : +value:cat* +lang:null <pre></code> @Entity() @Table(name="indexing_tag_trans") @org.hibernate.annotations.Cache(usage=org.hibernate.annotations.CacheConcurrencyStrategy.READ_WRITE) @Indexed public class TagTranslation implements java.io.Serializable { private static final long serialVersionUID = -1065316566731456110L; @Id @GeneratedValue(strategy=GenerationType.IDENTITY) @DocumentId private Integer id; @Field(index=Index.UN_TOKENIZED, store=Store.NO) private String language; @Field(index=Index.TOKENIZED, store=Store.YES) private String value; @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.LAZY) @org.hibernate.annotations.Fetch(org.hibernate.annotations.FetchMode.SUBSELECT) @JoinColumn(name="translation_id") @IndexedEmbedded private List<TagVariation> variations = new LinkedList<TagVariation>(); public TagTranslation() { } ... </code> </pre> What do you think about that ?

[Hibernate-JIRA] Created: (HSEARCH-119) Enable lucene similarity seach based on term frequency vector by QBE-like query

by Xin Wu (JIRA)

Enable lucene similarity seach based on term frequency vector by QBE-like query --------------------------------------------------------------------------------- Key: HSEARCH-119 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-119 Project: Hibernate Search Issue Type: New Feature Reporter: Xin Wu Scenario: Your bookstore application needs a function as follow: When a user see a list of books, there is a similar books button for each book. If user clicks this button of one book item, the similar books will be listed. The similarity is evaluated by all terms in summary of the book and similarity score is dirived from Lucene search similarity package which uses term frequency vectors in calculation. It will compare the target in all corresponding documents in the index and return the hits in order. Note: this funtion is not same as fuzzy query which still needs a definite query condition. In the contrast, similarity search only needs one or several fields (of object/document)to be specified and the rest will be automatically caculated by lucene. A QBE-like API should be used to make such query. You can specify the fields in such query. Please see discussion about this topic in the forum: http://forum.hibernate.org/viewtopic.php?t=979692 -- 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
