[Hibernate-JIRA] Created: (HHH-5590) Don't log and rethrow exceptions in AbstractFlushingEventListener

by Gregg (JIRA)

Don't log and rethrow exceptions in AbstractFlushingEventListener ----------------------------------------------------------------- Key: HHH-5590 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5590 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.0.CR1, 3.5.6, 3.3.2 Environment: Hibernate 3.3.2.GA Oracle Database 10.1.0.4.0 JDK 1.6.0_17 Reporter: Gregg Priority: Trivial Attachments: AbstractFlushingEventListener.patch For a similar issue covering logging-and-rethrowing overall, see http://opensource.atlassian.com/projects/hibernate/browse/HB-1308. This issue covers a specific instance in order to minimize the impact on the codebase. However, I would be all for elimination of every instance of log-and-rethrow in the codebase. In this particular instance, I have a table A with a foreign key referencing records in table B. In my user interface, I give the user the ability to delete records from table B. If the user attempts to delete a record from table B that is referred to in table A, the database throws an integrity constraint violation. This exception is caught in AbstractFlushingEventListener.performExecutions, logged, and rethrown. My code sees the exception and informs the user that the record cannot be deleted because it's already in use in the system. So the exception ends up showing up in my logs (from the log.error() statement in AbstractFlushingEventListener.performExecutions) even though I'm handling it properly. I would like the log.error() statement removed since the code propagates the exception. Attached is a patchfile. I'm not including a test case because I feel the issue is so simplistic that one isn't necessary. -- 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

by Emmanuel Bernard (JIRA)

Services can be initialized lazily which means several threads can end up asking for the same service in // The implementation needs to guard against that. note that using a ConcurrentHashMap is not good enough as we probably don't want the same service type to be initialized multiple times. -- 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-3494) HQLQueryPlan gives back zero result for "getSingleResult()" although one result is available

by Christian Hofschroer (JIRA)

HQLQueryPlan gives back zero result for "getSingleResult()" although one result is available -------------------------------------------------------------------------------------------- Key: HHH-3494 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3494 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.1 Environment: 3.3.1.GA, hsqldb 1.8.0.7 Reporter: Christian Hofschroer Attachments: patch.txt I have run the following code snippets both and only the second one works, because there is a bug in HQLQueryPlan. // This does not work correctly (query is javax.persistence.Query) ExampleObject e = (ExampleObject) query.getSingleResult(); // Replacement with this code works List l=query.getResultList() ; assertEquals(1,l.size()) ; ExampleObject e=(ExampleObject)l.get(0) ; This problem occurs only in seldom cases when 1. Hibernate executes several sql queries and merges the result and 2. There is a limit of results (the limit is "2" in version 3.3.1.GA, because only one result is expected anyway) Attached is a patch for the class HQLQueryPlan. The line if ( distinction.add( result ) ) { has to be replaced with if ( ! distinction.add( result ) ) { In case the object was found it returns "true". With the current implementation the object is not added to "combinedResults" although it should be added. It was not possible to reproduce the problem with the setup from "testsuite". If necessary I can provide a JUnit testcase. -- 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
