Subject [jira] Updated: (DERBY-4343) ASSERT FAILED calling setTransactionIsolation checking isolation_ == level on pooled connection
Date Thu, 06 May 2010 06:31:48 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4343?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lily Wei updated DERBY-4343:
----------------------------

    Attachment: DERBY-4343-testcase.diff

With fix for DERBY-4314, this issue has been resolved also.
I am adding test case with four connections on ClientConnectionPoolDataSource to J2EEDataSource
Test test. From testing structure point of view, it is easier to add to J2EEDataSourceTest
instead of setTransactionIsolationTest.
The case where we execute a statement in local transaction within global transaction is also
added. Thx, Lily

> For DERBY-4314, I thought I would do a little testing to understand the server round
trips in various scenarios for pooled connections.  So I wrote the small attached program
ConnReuse.java and hit this assertion in client:
> Exception in thread "main" org.apache.derby.shared.common.sanity.AssertFailure: ASSERT
FAILED
>         at org.apache.derby.shared.common.sanity.SanityManager.ASSERT(SanityManager.java:98)
>         at org.apache.derby.client.am.Connection.setTransactionIsolationX(Connection.java:987)
>         at org.apache.derby.client.am.Connection.setTransactionIsolation(Connection.java:915)
>         at org.apache.derby.client.am.LogicalConnection.setTransactionIsolation(LogicalConnection.java:253)
>         at TestConnReuse.main(TestConnReuse.java:32)
> ---------------
> To run the program on trunk:
> java org.apache.derby.drda.NetworkServerControl start
> java TestConnReuse.
> This needs more investigation, but I thought I would go ahead and log the bug.  I tried
this only on  trunk.  I  have not yet
> - Tried it on the branches.
> - Tried it with Lily's DERBY-4314 patch.
> - Tried it with embedded.
> - Tried actually doing something with the prior logical connection which might be related.
