[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-6607) Exceptions being hidden in JDBCTransation

Exceptions being hidden in JDBCTransation ----------------------------------------- Key: HHH-6607 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6607 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.6.7 Environment: The issue happens when the audit schema is different from the primary schema say because of a column change. The database session is rolled back but the exception isn't thrown up to any levels past the notifyLocalSynchsBeforeTransactionCompletion() so any applications needing to recover from database failures cannot - say rolling back application caches. The way to reproduce this is to drop a column in the aud table for any domain object and try to insert the data Reporter: Rich Christy Assignee: Lukasz Antoniak Fix For: 4.x, 3.6.7 2011-08-24 16:00:15,886 ERROR [AbstractFlushingEventListener] Could not synchronize database state with session org.hibernate.exception.SQLGrammarException: Could not execute JDBC batch update at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:90) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:275) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:114) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:109) at org.hibernate.jdbc.AbstractBatcher.prepareBatchStatement(AbstractBatcher.java:244) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2242) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2678) at org.hibernate.action.EntityInsertAction.execute(EntityInsertAction.java:79) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:279) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:263) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:167) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:321) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:50) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1028) at org.hibernate.envers.synchronization.AuditSync.beforeCompletion(AuditSync.java:161) at org.hibernate.transaction.JDBCTransaction.notifyLocalSynchsBeforeTransactionCompletion(JDBCTransaction.java:274) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:140) at org.openspaces.persistency.hibernate.DefaultHibernateExternalDataSource.executeBulk(DefaultHibernateExternalDataSource.java:107) at com.skyroad.motion.transactionmanager.util.TransactionMirrorExternalDataSource.executeBulk(TransactionMirrorExternalDataSource.java:32) What the code is doing in the exception handling of AuditSync.java (5th line from the bottom in the stack track) is rolling back the transaction as far as the hibernate session is concerned and then unconditionally throwing the exception to the next level. However, the code in notifyLocalSynchsBeforeTransactionCompletion() eating the exception so Gigaspaces isn't aware that it happened. This would explain why the database writes are rolled back but the space isn't. public void beforeCompletion() { if (workUnits.size() == 0 && undoQueue.size() == 0) { return; } try { // see: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4178431 if (FlushMode.isManualFlushMode(session.getFlushMode()) || session.isClosed()) { Session temporarySession = null; try { temporarySession = session.getFactory().openTemporarySession(); executeInSession(temporarySession); temporarySession.flush(); } finally { if (temporarySession != null) { temporarySession.close(); } } } else { executeInSession(session); // Explicity flushing the session, as the auto-flush may have already happened. session.flush(); } } catch (RuntimeException e) { // Rolling back the transaction in case of any exceptions //noinspection finally try { if (session.getTransaction().isActive()) { session.getTransaction().rollback(); } } finally { //noinspection ThrowFromFinallyBlock throw e; } } } private void notifyLocalSynchsBeforeTransactionCompletion() { if (synchronizations!=null) { for ( int i=0; i<synchronizations.size(); i++ ) { Synchronization sync = (Synchronization) synchronizations.get(i); try { sync.beforeCompletion(); } catch (Throwable t) { log.error("exception calling user Synchronization", t); } } } }
