[Hibernate-JIRA] Created: (HHH-3008) Cascade delete does not work with unidirectional @OneToMany and @JoinTable

by Daniel Dyer (JIRA)

Cascade delete does not work with unidirectional @OneToMany and @JoinTable -------------------------------------------------------------------------- Key: HHH-3008 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3008 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: Standalone entity manager (JavaSE 5.0). H2 database. Reporter: Daniel Dyer A unidirectional one-to-many relationship defined as follows: public class Owner { @OneToMany(cascade = CascadeType.ALL) @JoinTable(name = "owner_element", joinColumns = @JoinColumn(name = "owner_id", nullable = false, updatable = false), inverseJoinColumns = @JoinColumn(name = "element_id", nullable = false, updatable = false)) private List<Element> elements; // ... } Attempting to delete an instance of Owner should also delete all associated instances of Element. Instead I get the following error: SEVERE: Referential integrity constraint violation: FK56BBF9C487E817D: PUBLIC.OWNER_ELEMENT FOREIGN KEY(OWNER_ID) REFERENCES PUBLIC.OWNER(ID) [23003-63] This is because Hibernate attempts to delete the Owner row without first removing the rows from the join table. -- 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-4722) Proxy initialization should be fail-fast when accidentially initializing from event listeners or interceptor

by Joonas Koivunen (JIRA)

Proxy initialization should be fail-fast when accidentially initializing from event listeners or interceptor ------------------------------------------------------------------------------------------------------------ Key: HHH-4722 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4722 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Environment: Hibernate 3.2.2 Reporter: Joonas Koivunen Proxy initialization done in event listeners (at least post-update) with an entity that has a mapped collection seems to result in {code}org.hibernate.AssertionFailure: collection [role-of-collection] was not processed by flush(){code} at flush time. By googling up problems like the above assertion failure seems that other people than me have spent quite a time searching for the origin of this problem; for me it was using a toString() of an uninitialized proxy. -- 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-2989) @Loader using named queries returns null

by Jose Noheda (JIRA)

@Loader using named queries returns null ---------------------------------------- Key: HHH-2989 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2989 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, Hibernate Annotations 3.3.0, Hibernate Entity Manager 3.3.1 Reporter: Jose Noheda When using entitymanager.find (class, pk) with a @Loader annotation declared the org.hibernate.persister.entity.NamedQueryLoader load function performs a query.list() call (line 57). This call returns a List of entities and the list is correctly filled with one entry (org.hibernate.impl.SessionImpl line 1121). After returning, the line 62 (of NamedQueryLoader): return session.getPersistenceContext().getEntity( new EntityKey( id, persister, session.getEntityMode() ) ) is unable to find it though. -- 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-1976) NamingStrategy.classToTableName receives only class name, not a fully qualified name as stated in javadoc

by Lóránt Pintér (JIRA)

NamingStrategy.classToTableName receives only class name, not a fully qualified name as stated in javadoc --------------------------------------------------------------------------------------------------------- Key: HHH-1976 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1976 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3, 3.2.0.cr2 Reporter: Lóránt Pintér I have a custom NamingStrategy that overrides classToTableName in EJB3NamingStrategy. Prior to upgrading to Hibernate 3.1.3, my NamingStrategy implementation received the correct classnames as documented in the javadoc at http://www.hibernate.org/hib_docs/v3/api/org/hibernate/cfg/NamingStrategy... Since then, it only receives the name of the class without the package specification. I tried upgrading to 3.2.0.cr2, but it didn't help. -- 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-2150) There are too many columns in the select statement with the Criteria API

by Slawek Trybus (JIRA)

There are too many columns in the select statement with the Criteria API ------------------------------------------------------------------------ Key: HHH-2150 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2150 Project: Hibernate3 Type: Improvement Components: query-criteria Versions: 3.2.0.ga Environment: Hibernate 3.2.0.cr2 PostgreSQL 8.1.3 Reporter: Slawek Trybus Using Criteria API brings on enclosing all columns from joined tables in generated select statement. It has big efficiency impact on DB especially if there are many joined tables (with many columns each) in a query. There is columns' limitation possible with the Projections API usage, but it makes received objects not fully fledged Hibernate entity objects. It would be good to have posibility to limit amount of columns in select statement to ones connected to entity we are interested in. There is available short discusion about this issue in the forum: http://forum.hibernate.org/viewtopic.php?t=965818 -- 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-3359) Loader leaks memory when ResultSet wrapping is enabled

by Frans Flippo (JIRA)

Loader leaks memory when ResultSet wrapping is enabled ------------------------------------------------------ Key: HHH-3359 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3359 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.3.0.CR1, 3.2.6 Environment: Hibernate 3.2.6 GA, Oracle 10g database, Oracle JDBC drivers 10.2.0.1.0 for JDK14 Reporter: Frans Flippo Priority: Minor Attachments: ResultSetWrapper.java This issue was already reported on the forums (http://forum.hibernate.org/viewtopic.php?t=968578), but I can find no actual JIRA entry. The issue is that when the hibernate.jdbc.wrap_result_sets property is set to true, ResultSets are never removed from the AbstractBatcher's resultSetsToClose set, eventually causing memory to fill up with ResultSet objects and their associated resources (like PreparedStatements). This issue was witnessed in 3.2.6, but a look at the 3.3 CR1 source code reveals that it's still in there. What happens: 1) org.hibernate.loader.Loader.doQuery calls org.hibernate.loader.Loader.getResultSet 2) org.hibernate.loader.Loader.getResultSet calls Batcher.getResultSet. The AbstractBatcher implementation creates a ResultSet by executing the query and adds it to the AbstractBatcher's resultSetsToClose Set 3) Loader then calls its wrapResultSetIfEnabled method to wraps the ResultSet in a ResultSetWrapper if the wrap_result_sets option is enabled. 4) In Loader.doQuery's finally block, Batcher.closeQueryStatement is called with the PreparedStatement and the *wrapped* ResultSet as parameters 5) closeQueryStatement does: if ( resultSetsToClose.remove( rs ) ) { logCloseResults(); rs.close(); } 6) resultSetsToClose.remove(rs) will always return false if the ResultSet was wrapped, as ResultSetWrapper does not override equals()/hashCode() (and therefore inherits Object's equals() and hashCode()). This means the reference to the original (unwrapped) ResultSet remains (is not removed from the Set) and the ResultSet is not closed either as a result. Workaround: Set hibernate.jdbc.wrap_result_sets to false Solution: implement ResultSetWrapper.equals()/hashCode() (see attached ResultSetWrapper.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: (HHH-3763) An optional "end revision" column

by Adam Warski (JIRA)

An optional "end revision" column --------------------------------- Key: HHH-3763 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3763 Project: Hibernate Core Issue Type: New Feature Components: envers Reporter: Adam Warski Assignee: Adam Warski The "end revision" column would be optionally generated (basing on a setting), and would contain the number of the revision to which the given data row in an audit table is valid. It would be null if a version is still valid. The column can be calculated basing on the "revision" + id columns, so it will create data redundancy, but it will help speed up queries a lot. -- 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
