[Hibernate-JIRA] Created: (HHH-3007) Unchanged persistent set gets marked dirty on session.merge()

by Lars Koedderitzsch (JIRA)

Unchanged persistent set gets marked dirty on session.merge() ------------------------------------------------------------- Key: HHH-3007 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3007 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Reporter: Lars Koedderitzsch Persistent sets are marked dirty on session.merge() even if there have been no changes to the collection. This is especially painful when the collection is immutable and results in an "changed an immutable collection instance" exception on flush. I tracked the behaviour down a bit and believe the problem to be in CollectionType.replace(). Here the passed in orginal PersistentSet is replaced by a plain HashSet in this line: Object result = target == null || target == original ? instantiateResult( original ) : target; The "result" object (HashSet) is then passed to the CollectionType.replaceElements() method (instead of the original PersistentSet). In CollectionType.replaceElements() the code to clear the dirty state of the collection does not execute anymore, because the passed-in "original" collection is the described HashSet and *not* the original PersistentSet. This way the PersistentSet remains marked dirty. A workaround is to manually clear the dirty state of an immutable collection after merge but before flush. -- 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-3527) Null Version Comparator for versioned class due to reuse of Second Level CacheDataDescriptionImpl

by Paul FitzPatrick (JIRA)

Null Version Comparator for versioned class due to reuse of Second Level CacheDataDescriptionImpl ------------------------------------------------------------------------------------------------- Key: HHH-3527 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3527 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.3.1 Environment: 3.3.1 GA, Postgres 8.3.3, EH Cache Reporter: Paul FitzPatrick Priority: Minor When the SessionFactoryImpl constructor builds the EntityPersister for classes, it consults a cache of entityAccessStrategies for all the known second level cache regions. If only some of the classes in that region have version tags, then it is possible the cached EntityRegionAccessStrategy will be created without a Version Comparator. Subsequent calls to load an object using a Criteria query failed with a NullPointerException (stack trace below). The line being executed is "return version!=null && comparator.compare(version, newVersion) < 0;" and in this case "version" is an Integer object and comparator is null. Not sure the appropriate solution. It would seem from an examination of the code that if the EntityRegionAccessStrategy is to be shared, then all classes in the second level cache region _must_ either all have a "version" column or all have no "version" column. Further, it seems implied that if they use a "version" column, then they must all use the exact same data type. If this is the case, then a better error check on the configuration data may be in order.

[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: (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
