[Hibernate-JIRA] Created: (HHH-3940) Remove hasSelfReferentialForeignKeyBug (returning true) override from MySQL dialects

by Steve Ebersole (JIRA)

Remove hasSelfReferentialForeignKeyBug (returning true) override from MySQL dialects ------------------------------------------------------------------------------------ Key: HHH-3940 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3940 Project: Hibernate Core Issue Type: Task Components: core Affects Versions: 3.3.1, 3.2.7 Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.2.x, 3.3.x, 3.5 Previous versions of MySQL had a nasty bug when using self-referential foreign keys with the innodb storage engine. This Dialect#hasSelfReferentialForeignKeyBug was originally added to account for that. Testing against the lastest (5.1) MySQL versions shows this to no longer be present. -- 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-3995) Cleanup test data

by Steve Ebersole (JIRA)

Cleanup test data ----------------- Key: HHH-3995 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3995 Project: Hibernate Core Issue Type: Task Components: testsuite Reporter: Steve Ebersole Assignee: Steve Ebersole Priority: Minor Fix For: 3.2.x, 3.3.x, 3.5 Lots of tests are leaving test data hanging around. That works on a particular assumption wrt the execution order of tests or that only a single test method exists. That cuases problems later in many cases. All tests should clean up the test data they create. Currently on trunk I see 246 tests leaving data around. The sys prop hibernate.test.validateDataCleanup can be used to check for this; set it to true. -- 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-3946) Test FooBarTest isn't opening transactions and contains an invalid assertion

by Juraci Paixao Krohling (JIRA)

Test FooBarTest isn't opening transactions and contains an invalid assertion ---------------------------------------------------------------------------- Key: HHH-3946 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3946 Project: Hibernate Core Issue Type: Bug Components: testsuite Reporter: Juraci Paixao Krohling Assignee: Juraci Paixao Krohling Fix For: 3.5 Attachments: FooBarTest.java.diff Test FooBarTest have three tests failing: - testDisconnect - testOrderBy - testVeto All of them are issuing commit to transactions which were not started, causing "Transaction not successfully started" error. Also, the test testOrderBy contains an invalid assertion. The code reads: assertEquals( "'b' isn't second element", "b", ( (One) results.get(2) ).getValue() ); But as the method "get" is 0-indexed, the parameter should be 1, instead of 2. The attached patch fixes those issues. -- 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-4035) skip org.hibernate.action.BulkOperationCleanupAction on INSERT HQL queries

skip org.hibernate.action.BulkOperationCleanupAction on INSERT HQL queries -------------------------------------------------------------------------- Key: HHH-4035 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4035 Project: Hibernate Core Issue Type: Improvement Components: caching (L2) Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.3.x, 3.5 For INSERT queries it is really not needed to cleanup caches as we'd have no invalid entity/collection data to cleanup (we'd still nee to invalidate the appropriate update-timestamps regions) as a result of the query. -- 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-2309) fetch only the lazy property needed

by German de la Cruz (JIRA)

fetch only the lazy property needed ------------------------------------ Key: HHH-2309 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2309 Project: Hibernate3 Type: New Feature Components: core Versions: 3.2.1 Reporter: German de la Cruz The method AbstractEntityPersister.initializeLazyProperty(..) load all lazy properties when it's called. It would be great if could only load the requested property. I think the only change we need is in AbstractEntityPersister.initializeLazyPropertiesFromDatastore(...) and AbstractEntityPersister.initializeLazyPropertiesFromCache(...). We must change them in a way that only the referenced property is loaded. After that, we must change AbstractFieldInterceptor.intercept(..) to update in a better way the unitializedFields collection (I mean, removing the actual property only instead of null it). Besides. Why in line 777 to 780 a query is executed? I think it isn't necessary.

[Hibernate-JIRA] Erstellt: (HHH-2224) executeUpdate causes coarse cache invalidation

by Stefan Fleiter (JIRA)

executeUpdate causes coarse cache invalidation ---------------------------------------------- Key: HHH-2224 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2224 Project: Hibernate3 Type: Improvement Versions: 3.2.0.ga Environment: Hibernate 3.2.0.ga, Oracle 9.2 Reporter: Stefan Fleiter Attachments: bulk_testcase.zip I am developing an application and want to mix bulk-updates with normal hibernate operations. The bulk updates work fine, but invalidate the whole region and I've found no possibility to prevent this. There would be 3 options to improve: - Invalidate only the modified objects if the ids where given as Query-parameters. - Let me deactivate the invalidation so I can invalidate the affected objects myself. - Transform the DML to a select to gather the objects to invalidate before executing the DML The reference documentation does not mention caching at all: http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#batch-direct The best documentation I've found is: http://blog.hibernate.org/cgi-bin/blosxom.cgi/2005/07/19#dml-basic Maybe this could be added to the reference documentation... I already posted this at the forum http://forum.hibernate.org/viewtopic.php?t=966775 but did not get a single answer. I've attached a testcase for this. -- 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-2470) Use of session.createSQLQuery causes memory leak

by Bjørn Bjerkeli (JIRA)

Use of session.createSQLQuery causes memory leak ------------------------------------------------- Key: HHH-2470 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2470 Project: Hibernate3 Type: Bug Components: query-sql Versions: 3.1.3 Environment: Win XP, Oracle 10g, Java 1.4.2 Reporter: Bjørn Bjerkeli Attachments: TestCase.zip NativeSQLQuerySpecification fails to properly implement equals and hashcode caused by lacking implementation of hashCode and equals in all SQLQueryReturn implementations and SQLQueryScalarReturn which are members of NativeSQLQuerySpecification. I can see that NativeSQLQuerySpecification has been changed in 3.2, but the problem is still there. NativeSQLQuerySpecification instances are used as keys for retrieving and caching NativeSQLQueryPlan instances. This causes the caching-mechanism to be pretty useless when Queries created by session.createSQLQuery because new entries will be added all the time in the QueryPlanCache and the SoftLimitMRUCache member. So far so good, the more serious problem that is caused by this is stems from the implementation of SoftLimitMRUCache which again uses LRUMap in commons-collection. The put - method of the cache is not treadsafe, and that causes the following fragment in LRUMap to allow the map to grow beyond its maximumSize. That is bacause the containsKey method will return an incorrect result when concurrently updating the map. public Object put( Object key, Object value ) { int mapSize = size(); Object retval = null; if ( mapSize >= maximumSize ) { // don't retire LRU if you are just // updating an existing key if (!containsKey(key)) { // lets retire the least recently used item in the cache removeLRU(); } } retval = super.put(key,value); return retval; } I have included a test-case that demonstrates: 1) Wrong implementation of equals and hashCode in NativeSQLQuerySpecification 2) Concurrent use of LRUMap causes the map to grow beyound it's max limit 3) Concurrent execution of session.createSQLQuery causes memory leak due to 1) and 2) I would be more than happy to contribute to get this fixed. Just let me know. -- 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-3221) Cascading performance problems when session contains many entities

by Yves Galante (JIRA)

Cascading performance problems when session contains many entities ------------------------------------------------------------------ Key: HHH-3221 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3221 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.3.0.CR1, 3.2.6, 3.2.5 Reporter: Yves Galante Attachments: patchCascading.patch, SaveTest.zip When session contains many entities, performence of cascading become very slow. For each collection element the whole persistence context is searched (by StatefulPersistenceContext#getIndexInOwner() and StatefulPersistenceContext#getOwnerId) and its even searched twice when the collection is an indexed collection. This patch optimize cascading operation by caching relation parent-child on a map. eventSource.getPersistenceContext().addChildParent(child, parent); action.cascade(eventSource, child, entityName, anything, isCascadeDeleteEnabled); eventSource.getPersistenceContext().removeChildParent(child); The test case save and flush 10 * 551 objects. Before patch save object with cascading is more slow when session size grows. After patch time of save stay same at each loop. Output of the test case before the patch : Save took 449 ms Save took 669 ms Save took 1042 ms Save took 1464 ms Save took 2481 ms Save took 2741 ms Save took 3807 ms Save took 4344 ms Save took 4975 ms Save took 5251 ms Total took 30906 ms Output after the patch Save took 445 ms Save took 144 ms Save took 164 ms Save took 108 ms Save took 93 ms Save took 93 ms Save took 93 ms Save took 94 ms Save took 91 ms Save took 89 ms Total took 4905 ms -- 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
