Subject running SecureServerTest concurrently?
Date Wed, 15 Jun 2011 01:52:12 GMT
Hi,

I've been stumped by some odd behavior.
I've been trying to get a number of concurrent suites.All runs (each
with a different location & jvm & a different value for
-Dderby.tests.basePort) to go, and apart from an intermittent
replication test failure, only SecureServerTest fails regularly. So
I've switched to running only SecureServerTest concurrently (instead
of suites.All).

I'm using a Windows XP machine, with 2 CPUs, and it has been
configured to do hyperthreading, so Windows thinks there are 4 CPUs.

I've seen 4 concurrent runs pass, but also seen some of those fail.

The failure seems to be that there's no output coming from the server.
For instance (running junit.textui.TestRunner with
-Dderby.tests.trace=true and -Dderby.tests.debug=true):

1) SecureServerTest( Opened = false, Authenticated= true,
CustomDerbyProperties= null, WildCardHost= 0.0.0.0
)junit.framework.AssertionFailedError: Security exceptions in output
of trace enabling command:

I've tried thought that perhaps there should be some more time between
the runServerCommand and the check, so I added Thread.sleep(200) after
every call, but that didn't help.
I've also tried to change
org.apache.derbyTesting.junit.SpawnedProcess.getFullServerOutput()  to
return this:
 return "out: " +  out.toString() + "\nerr: " + err.toString() ;
But the contents were still empty, and err.toString never has anything.

If anyone has any suggestions/hints on what might be wrong, or other
things to experiment with, please let me know...

Thanks,
Myrna
