[Hibernate-JIRA] Created: (HHH-3058) When using native sql query and multiple selects with setMaxResults, Hibernate inserts the TOP statement in the first query

by Sean Blaes (JIRA)

When using native sql query and multiple selects with setMaxResults, Hibernate inserts the TOP statement in the first query --------------------------------------------------------------------------------------------------------------------------- Key: HHH-3058 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3058 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.2.4.sp1 Environment: Hibernate 3.2.4sp1, Microsoft SQL Server Reporter: Sean Blaes Priority: Minor When using a query similar to the following: DECLARE @SUB_TABLE TABLE( ID INT ) INSERT INTO @SUB_TABLE SELECT ID FROM FOO SELECT * FROM BAR INNER JOIN @SUB_TABLE ON ... Then if I call setMaxResults(100) on the query object. It inserts "TOP 100" in the first query, which isn't really what would be expected. Since the second SELECT actually consists of the data that will be returned, the TOP 100 statement should go there. I'd expect it's an easy fix. Just start your search for SELECT from the bottom rather than the top. However, I guess you have to make sure you're not hitting a subquery of a larger select either... I may try cooking up a patch this weekend for this if I can find the time, and I'll attach it to this issue if I do. -- 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-1989) Deleted object remains referenced in 2nd level cache collections

by Justin Haddad (JIRA)

Deleted object remains referenced in 2nd level cache collections ---------------------------------------------------------------- Key: HHH-1989 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1989 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2 Environment: Spring 1.2.8, Hibernate 3.2, Postgres 8.0.3 Reporter: Justin Haddad This problem seems identical to issue NH-678. I have enabled caching for an one-to-many association. I use Ehcache. I have a test in which I load the parent object along with its collection. Both the parent and the collection wind up in the 2nd level cache. I then delete an object that is in the collection, not by removing it from the collection, but rather by doing a delete on the object itself. After deleting, I try to reload the parent and get the following exception (User#3102 is the deleted object): aused by: org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.bluenotenetworks.common.management.sm.User#3102] at org.hibernate.impl.SessionFactoryImpl$1.handleEntityNotFound(SessionFactoryImpl.java:372) at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:128) at org.hibernate.event.def.DefaultLoadEventListener.proxyOrLoad(DefaultLoadEventListener.java:178) at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:86) at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:871) at org.hibernate.impl.SessionImpl.internalLoad(SessionImpl.java:839) at org.hibernate.type.EntityType.resolveIdentifier(EntityType.java:266) at org.hibernate.type.ManyToOneType.assemble(ManyToOneType.java:177) at org.hibernate.collection.PersistentSet.initializeFromCache(PersistentSet.java:101) at org.hibernate.cache.entry.CollectionCacheEntry.assemble(CollectionCacheEntry.java:35) at org.hibernate.event.def.DefaultInitializeCollectionEventListener.initializeCollectionFromCache(DefaultInitializeCollectionEventListener.java:130) at org.hibernate.event.def.DefaultInitializeCollectionEventListener.onInitializeCollection(DefaultInitializeCollectionEventListener.java:48) at org.hibernate.impl.SessionImpl.initializeCollection(SessionImpl.java:1705) (continues on) I stepped through the code in the debugger and can see that the object's ID (3102 in this case) remains in the cached collection even after the deletion. -- 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-3075) Should be possible to register UserTypes for known property types (classes) in configuration

by Martin Probst (JIRA)

Should be possible to register UserTypes for known property types (classes) in configuration -------------------------------------------------------------------------------------------- Key: HHH-3075 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3075 Project: Hibernate3 Issue Type: Improvement Components: core Environment: n/a Reporter: Martin Probst Priority: Minor Currently, when persisting primitive properties of a class that are not known to Hibernate, there are only cumbersome ways to tell Hibernate that a certain UserType should be used. Good example is Joda Time: <pre> @Entity class MyClass { org.joda.time.DateTime foo; } </pre> .. which will result in ugly binary fields in database. Next try: <pre> @Entity class MyClass { @Type(type = "org.joda.time.contrib.hibernate.PersistentDateTime") org.joda.time.DateTime foo; } </pre> That works, but now I have to specify that on all time fields of all classes. Plus it's different types for different classes, which makes it more messy. And it's simply a string in code, so it's fragile to refactoring, code move, etc. TypeDefs allow a shorter handle for certain types, but don't really address the refactoring issues. A better way might be to allow configurations to register UserTypes for known classes. E.g. have a configuration directive like this: <mappable-type class="org.joda.time.DateTime" usertype="org.joda.time.hibernate.DateTimeType"/> This would allow the classes to stay clean from type mappings and reduce coupling between domain objects and persistence mapping. This might be as easy as allowing the org.hibernate.type.TypeFactory map to be extended at configuration time. -- 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-2645) Synchronization bottleneck in EntityModeToTuplizerMapping

by Erik Bergersjö (JIRA)

Synchronization bottleneck in EntityModeToTuplizerMapping --------------------------------------------------------- Key: HHH-2645 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2645 Project: Hibernate3 Issue Type: Patch Components: core Affects Versions: 3.2.4.sp1, 3.2.4, 3.2.3 Environment: Hibernate 3.2.3 (and later), Sun's JDK 1.4.2_12 (server VM) on SunOS 5.10, Oracle 10g R2 Reporter: Erik Bergersjö Priority: Minor We have had a major performance bottleneck in EntityModeToTuplizerMapping with Hibernate version 3.2.3 and the code for that class in 3.2.4sp1 is unchanged. We have found a solution that solves the issue and would like to get it into the real version. I submitted to the user forum first and was asked to create a JIRA issue. The problematic line is: private final Map tuplizers = Collections.synchronizedMap( new SequencedHashMap() ); We have changed it to (using util.concurrent): private final Map tuplizers = new EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap(); This change alone makes our use cases six times faster. The difference is that ConcurrentReaderHashMap handles concurrent readers much better, they don't have to wait for each other. The problem occurs when a high number of threads try to initialize sets (see mapping below). A thread dump showed a high number of threads waiting for the same monitor, see partial stack trace below. The code runs on Sun's JDK 1.4.2_12 (server VM) on SunOS 5.10 and the kernel spends a lot of time handling mutexes with the original implementation. That time disappears from the radar screen with the fixed version. Example mapping for set: [code] <set name="lines" lazy="true" inverse="true" cascade="all-delete-orphan"> <key> <column name="col1" not-null="true" /> <column name="col2" not-null="true" /> </key> <one-to-many class="LineClass" /> </set> [/code] Stack trace (partial): "Thread-108" prio=5 tid=0x05852e90 nid=0x103 waiting for monitor entry [0x3ed7e000..0x3ed7fc28] at java.util.Collections$SynchronizedMap.get(Collections.java:1942) - waiting to lock <0x89d30788> (a java.util.Collections$SynchronizedMap) at org.hibernate.tuple.EntityModeToTuplizerMapping.getTuplizerOrNull(EntityModeToTuplizerMapping.java:53) at org.hibernate.tuple.EntityModeToTuplizerMapping.getTuplizer(EntityModeToTuplizerMapping.java:66) at org.hibernate.type.ComponentType.getPropertyValues(ComponentType.java:353) at org.hibernate.type.ComponentType.isEqual(ComponentType.java:141) at org.hibernate.engine.CollectionKey.equals(CollectionKey.java:50) at java.util.HashMap.eq(HashMap.java:274) at java.util.HashMap.get(HashMap.java:323) at org.hibernate.engine.loading.CollectionLoadContext.getLocalLoadingCollectionEntry(CollectionLoadContext.java:163) at org.hibernate.engine.loading.CollectionLoadContext.locateLoadingCollectionEntry(CollectionLoadContext.java:150) at org.hibernate.engine.loading.CollectionLoadContext.getLoadingCollection(CollectionLoadContext.java:92) at org.hibernate.loader.Loader.readCollectionElement(Loader.java:1003) at org.hibernate.loader.Loader.readCollectionElements(Loader.java:646) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:591) at org.hibernate.loader.Loader.doQuery(Loader.java:701) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:236) at org.hibernate.loader.Loader.loadCollection(Loader.java:1994) at org.hibernate.loader.collection.CollectionLoader.initialize(CollectionLoader.java:36) at org.hibernate.persister.collection.AbstractCollectionPersister.initialize(AbstractCollectionPersister.java:565) at org.hibernate.event.def.DefaultInitializeCollectionEventListener.onInitializeCollection(DefaultInitializeCollectionEventListener.java:60) at org.hibernate.impl.SessionImpl.initializeCollection(SessionImpl.java:1716) at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:344) at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86) at org.hibernate.collection.PersistentSet.iterator(PersistentSet.java:163) -- 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-3050) Convert usage of Hibernate's FastHashMap to ConcurrentHashMap (Java 1.5)

by Gail Badner (JIRA)

Convert usage of Hibernate's FastHashMap to ConcurrentHashMap (Java 1.5) ------------------------------------------------------------------------ Key: HHH-3050 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3050 Project: Hibernate3 Issue Type: Improvement Reporter: Gail Badner Assignee: Gail Badner Fix For: 3.3 The performance test attached to HHH-2645 shows that java.util.concurrent.ConcurrentHashMap (introduced in Java 1.5) performs nearly as well as org.hibernate.util.FastHashMap. Hibernate needs to move to Java 1.5 before this can be done. As noted in HHH-2645, it might be worthwhile to convert usages of FastHashMap to ConcurrentHashMap so that FastHashMap does not need to be maintained. -- 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-168) Add the ability to disable automatic indexing both on a per index level and programmatically

by Eric Winter (JIRA)

Add the ability to disable automatic indexing both on a per index level and programmatically -------------------------------------------------------------------------------------------- Key: HSEARCH-168 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-168 Project: Hibernate Search Issue Type: New Feature Components: engine Reporter: Eric Winter Priority: Minor It is very resticitive in an application that has multiple indexes to only allow the disabling of automatic indexing on an application wide level (or at least SessionFactory wide...). I can see it being very useful to have auto indexing on a per index basis. Also, it would be nice to be able to turn auto indexing off and on programmatically using something like Search.setAutoIndexing("myIndex", false); //per index and Search.setAutoIndexing(false); //global -- 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-3884) NPE with mutable Natuarl Id's

by Michael Kopp (JIRA)

NPE with mutable Natuarl Id's ----------------------------- Key: HHH-3884 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3884 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.2 Reporter: Michael Kopp When saving an entity with a mutable natural id hibernate throws the following NPE. java.lang.NullPointerException at org.hibernate.engine.StatefulPersistenceContext.getNaturalIdSnapshot(StatefulPersistenceContext.java:267) at org.hibernate.event.def.DefaultFlushEntityEventListener.checkNaturalId(DefaultFlushEntityEventListener.java:78) at org.hibernate.event.def.DefaultFlushEntityEventListener.getValues(DefaultFlushEntityEventListener.java:162) at org.hibernate.event.def.DefaultFlushEntityEventListener.onFlushEntity(DefaultFlushEntityEventListener.java:113) at org.hibernate.event.def.AbstractFlushingEventListener.flushEntities(AbstractFlushingEventListener.java:196) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:76) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) I checked the code and found the reason: - getNaturalIdSnapshot calls getDatabaseSnapshot and checks the result for NO_ROW but not for null - getDatabaseSnapshot will never return NO_ROW but null if nothing was found hence getNaturalIdSnapshot will produce a NPE if the entity is not in the database already. the fix is simple: change: Object[] entitySnapshot = getDatabaseSnapshot( id, persister ); if ( entitySnapshot == NO_ROW ) { return null; } to Object[] entitySnapshot = getDatabaseSnapshot( id, persister ); if ( entitySnapshot == null ) { return null; } This is still there in trunk 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
