Sunitha Kambhampati updated DERBY-1114:
---------------------------------------
Attachment: Derby1114.diff.txt
Per the discussion on 1080, one reasonable course of action was to remove the
switching of streams in testSecMec.java to see if it solves the intermittent
failure. So, I am attaching this patch Derby1114.diff.txt to remove the
logic for switching of streams in testSecMec.java.
Bryan - thanks for running this test so many times for me. I appreciate it.
When you can, could you try this patch out and see if the intermittent problem
still reproduces. If it doesnt, then can this patch be committed ?
I ran this test 6 times on my linux machine and I didnt hit the intermittent
failure but so far I have not had any luck reproducing the failure. I have
started a derbynetmats and derbynetclientmats run. I'll post results as they
finish.
svn stat:
M
java\testing\org\apache\derbyTesting\functionTests\tests\derbynet\testSecMec.java
M
java\testing\org\apache\derbyTesting\functionTests\tests\derbynet\dataSourcePermissions_net.java
I will post the original testSecMec.java here, so it can be used to debug this
issue.
Thanks.

> The test derbynet/testSecMec.java fails intermittently in a strange way that
> the test actually exits before finishing the full test.
> This issue was noticed by Bryan when he ran derbyall with the derby-1080 fix.
> Some discussion and analysis that has been done is in Derby-1080. Please read
> comments in DERBY-1080. Some main links in
> http://issues.apache.org/jira/browse/DERBY-1080#action_12370260

> In short: the test does some switching of System.out and System.err streams
> before calling networkserver.shutdown. This code was added to this test as
> part of fix for derby-273. for some reason, the networkserver.shutdown call
> makes the test to exit. One theory is that the network server.shutdown is
> causing the standard out streams to close and thus the test exits.
> -- Need to investigate what is the cause for this intermittent failure and
> how/why networkserver.shutdown is closing the stream or making the test to
> exit prematurely.
