[jira] [Updated] (DERBY-5919) Network Server connection gets
destroyed after isValid(#) times out.
[ https://issues.apache.org/jira/browse/DERBY-5919?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kathey Marsden updated DERBY-5919:
----------------------------------
Issue & fix info: Newcomer,Repro attached
Urgency: Normal
Bug behavior facts: Crash,Embedded/Client difference
Labels: derby_triage10_10 (was: )
I think isValid will need an alternate mechanism than timing out the socket. Perhaps it would be worthwile to use the same mechanism as setQueryTimeout as long as it does not have the same problem.

> When a call to Connection.isValid(timoutvalue) actually times out, the connection is destroyed.
> For instance, the following test snippet:
> // Test with a large timeout, see DERBY-5912.
> boolean convalid=true;
> Connection conn=getConnection();
>
> // with a longer time out, the isValid call should not
> // time out when the sleep is shorter.
> convalid=conn.isValid(200);
> assertTrue(convalid);
>
> // setting the timeout to 1 should timeout if the sleep
> // is 2 seconds.
> convalid=conn.isValid(1);
> assertFalse(convalid);
>
> conn.rollback();
> Results in an assertion on the rollback:
> java.sql.SQLNonTransientConnectionException: No current connection.
