Subject [jira] [Commented] (DERBY-6179) Insert some guarding code into the first replication test to check port availability
Date Thu, 18 Apr 2013 05:17:15 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13634853#comment-13634853

Dag H. Wanvik commented on DERBY-6179:

Committed simplification as suggested by Knut in svn 1469165.
I have now seen a test run failing with this instrumentation in place, but the checks did
not trigger anything; still the slave failed with
its port being used. In my stand-alone run, I see the port number is different at the place
of the failure, so I'll add some temporary verbose chatter (forgive!;-)  to the log of the
regression for a bit to see which ports are actually checked and compare that with the busy
port number.

> We have seen lots of noise in the nightlies with replication failing. It seems that often
it fails due to ports being unavailable, possibly due to earlier (failed) runs.
> This JIRA issue tracks diagnostic code I want to insert to see what's happening at test
run time.
> The diagnostic code can be removed when we have stabilized the tests.
