Subject [jira] Commented: (DERBY-5137) Enable or remove Derby3980DeadlockTest
Date Wed, 16 Mar 2011 18:03:29 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007597#comment-13007597

Lily Wei commented on DERBY-5137:
---------------------------------

extendedDiagSeverity test exists for T_RawStoreFactory etc. The special policy file is added
to allow creating javadoc* file for ibm jvm. When doing the test, I did encounter issue in
turn of thread dump information did not show up in derby.log. However, due to need more synchronization
between the two threads, it might not be the most ideal case to add extenedDiagSeverity to
Derby3980DeadlockTest. it is fine with me to remove this test. Is it okay to add the extenedDiagSeverity
to DeadlockDetectionTest? I am still working on buddy testing JDBC 4.1. If it is okay to add
generating javadoc* file testing for extendedDiagSeverity to DeadlockDectioinTest. If it is
okay, I will add it after finish buddy testing. Thanks!

> As part of early work on DERBY-3980, I checked in  an unrun test for this issue when
I was working on it a long time ago, Derby3980DeadlockTest.   
> I verified it does pass now but maybe the new DeadLockDetectionTest  provides the same
coverage.
> This this test should be enabled or removed if it adds no additional coverage. 
> Derby3980DeadlockTest  does seem to have some testing for  extendedDiagSeverity level
and 
> diagProperties.setProperty("derby.stream.error.extendedDiagSeverityLevel", "30000");
> One thing to note is that it now, with the IBM JVM, I  think correctly will print 
> JVMDUMP010I Java dump written to ...
> I am surprised though not to see a thread dump in derby.log, so maybe there is an issue
with extendedDiagSeverity that needs to be looked at too.
