Subject [jira] [Updated] (DERBY-5708) simpleThread test doesn't release connection
Date Tue, 24 Apr 2012 12:25:34 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5708?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Knut Anders Hatlen updated DERBY-5708:

    Attachment: d5708-1a.diff

The attached patch makes simpleTest close and forget the connection before returning.

It also fixes another problem with the test: The test starts four threads that use a shared
connection to perform queries. However, it returns just after starting the tests, and doesn't
wait to see if the threads succeeded. The patch makes it wait until the threads have completed
before returning. (This part of the patch was needed to prevent the new cleanup code to close
and null out the connection before the threads were done with it.)

The test is still a bit strange, though. For example, it ignores exceptions in the threads.
Only wrong results cause a test failure.

> The simpleThread test, which is run by LangHarnessJavaTest, stores its connection in
a static field. It doesn't close the connection, or clear the static field, before returning.
So the connection is left open for the rest of the test run (potentially for the entire duration
of suites.All).
