Description Madhumita Sadhukhan 2012-04-12 14:35:08 UTC

I have verified that this is not DBAllocator issue as it can be seen that database allocation happens successfully .
However bunch of tests fail due to connection issues.

I think some test is opening too many connections on all the hit databases that is causing this.

This cannot be a DB or environmental issue as the testsuite passes with ER4.1(there has been a version upgrade from 4.1.1.Final to 4.1.2.Final between ER4.1 and ER5)

Comment 1 Rajesh Rajasekaran 2012-04-12 16:23:00 UTC
Madhumita, are you planning further investigation on this? I am also having this assigned to Strong, so he's aware of the regression from the JIRA notification.

Comment 2 Madhumita Sadhukhan 2012-04-12 17:09:17 UTC
Rajesh,

         yes I planned to assign it to Strong only after some more further investigation as the failures give different messages on different databases but I feel that this happens due to too many connections opened by some testcase added/modified in ER5.
However I still need to investigate the failures to find if there are multiple reasons why these fail as different number and different sets of tests fail on different DBs.
Also I was waiting for re-run against ER4.1 to complete to ensure that this is not an environmental(dballocator/DB server) issue at all and it already looks good

Comment 3 Madhumita Sadhukhan 2012-04-12 22:18:55 UTC
Strong,

       I started a separate run on few databases(DB2,Sybase,mysql55) with ER5 bits and the gradle patch but minus the LockModeTest(which was only hanging on DB2 and Sybase until ER4.1).Surprisingly this yielded successful testsuite run with few failures without above specified connection issues.

http://hudson.qa.jboss.com/hudson/view/EAP6/view/EAP6-Hibernate/job/eap6-hibernate-core-master-testsuite-testDB2Sybase/13/

Could you please confirm if something was modified in this test?
Hope this helps in nailing down the problem.

Comment 4 Madhumita Sadhukhan 2012-04-13 13:23:54 UTC
Seems like the culprit is indeed LockModeTest
Here comes a much stable run across all certified DBs with ER5 minus above test

Comment 5 Steve Ebersole 2012-04-15 23:41:59 UTC
I just do not see how LockModeTest results in the behavior you describe here.  The only thing I can think of is some kind of strange environment issue.  I am running Oracle Java 6 for Linux here and that test exhibits exactly the behavior it should.  What kind of environment are you using in these runs?

Comment 6 Steve Ebersole 2012-04-15 23:49:49 UTC
I guess it is possible that if some of these databases do not like the attempt to rollback the transaction from {{org.hibernate.test.locking.LockModeTest#nowAttemptToUpdateRow}} you could potentially see this problem (because closing the session would get skipped and therefore closing the connection would never happen).  Seems pretty far fetched, but I've seen JDBC drivers do worse.  We could try adding protections for that situation and see if it helps.


Comment 7 Strong Liu 2012-04-16 04:24:52 UTC
Steve,

seems like the _org.hibernate.testing.jta.TestingJtaBootstrap_ is the culprit, it opens too many connections but never close them

I tried run _org.hibernate.test.nonflushedchanges.MergeTest_ on my local with MySQL, and this only test case fails due to too many connections

Madhumita 

please give this patch a try

(do not remove LockModeTest)

even with my patch, there are even two connections living (see the time column)

Madhumita

why do you use 38a6c426ff1dc7a70f3eaec8ec90e744d02e1ae3 instead of the 4.1.2.Final?

Comment 14 Madhumita Sadhukhan 2012-04-16 08:27:02 UTC
Strong ,

          I am using 4.1.2.Final tag as you specified in both the jobs above.Will try your patch.

Comment 15 Steve Ebersole 2012-04-16 11:46:57 UTC
That patch wont work Strong.  Without it, connections are not bound to the JTA transactions.  There is a reason I added that ;)

So we need to find out how to get the Enhydra DataSource to actually release connections in this case.  That, or get IronJacamar actually figure out how to get Iron Jacamar to work outside AS and use it for DataSource

Comment 16 Madhumita Sadhukhan 2012-04-16 21:19:49 UTC
Steve/Strong,

Results after application of above patch as follows:

https://hudson.qa.jboss.com/hudson/view/EAP6/view/EAP6-Hibernate/job/eap6-hibernate-core-master-testsuite-testDB2Sybase/18/

Do not see above mass Connection failures
Apart from DB2 which hangs on LockModetest(already known issue) and oracle11gR1RAC which has dballocation issues(will be fixed soon)

Comment 17 Strong Liu 2012-04-17 03:20:04 UTC
https://hibernate.onjira.com/browse/HHH-7253 for those tests failing on oracle

Comment 18 Strong Liu 2012-04-19 10:05:09 UTC
Steve,

I haven't found a fix for this, can you give some help?

Comment 19 Steve Ebersole 2012-04-20 13:49:28 UTC
https://hibernate.onjira.com/browse/HHH-7266

Comment 20 Strong Liu 2012-04-23 09:19:53 UTC
according to the hudson result, now there is only two tests fail, so I'm closing this

CI reports:

1 test fails on mssql, oracle, postgresql

1 more test fails on postgresql

and that test hangs on DB2 issue

--------------------------

org.hibernate.envers.test.integration.inheritance.tableperclass.ParentAuditing is one of failing tests currently

( fails on ms sql server, postgresql )

this fails on the second run of the test (e.g. with property "org.hibernate.envers.audit_strategy" set to  "org.hibernate.envers.strategy.ValidityAuditStrategy")

and in the method  _org.hibernate.envers.strategy.ValidityAuditStrategy#perform_, it applies a UPGRADE lock to the query 

List<Object> l = qb.toQuery(session).setLockOptions(LockOptions.UPGRADE).list();

which then runs into this jira  https://hibernate.onjira.com/browse/HHH-3298

postgresql also has another failure, org.hibernate.envers.test.integration.inheritance.joined.ParentAuditing.initData

we had this before, see org.hibernate.test.legacy.FooBarTest#testQueryLockMode and org.hibernate.test.legacy.ParentChildTest#testComplexCriteria

in these two tests, we have this code:

LockMode lockMode = supportsLockingNullableSideOfJoin( getDialect() ) ? LockMode.UPGRADE : LockMode.READ;
	protected boolean supportsLockingNullableSideOfJoin(Dialect dialect) {
		// db2 and pgsql do *NOT*
		return ! ( DB2Dialect.class.isInstance( dialect ) || PostgreSQLDialect.class.isInstance( dialect ) );
	}

Link: Added: This issue is a dependency of JBPAPP-8827


Comment 22 Madhumita Sadhukhan 2012-05-02 08:52:09 UTC
We are able to run Hibernate testsuite with EAP6 ER6 without above mass failures due to too many open connections.
