Subject [jira] [Commented] (DERBY-6533) Add a quiet mode to NsTest
Date Mon, 14 Apr 2014 21:18:17 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13968854#comment-13968854
] 

Rick Hillegas commented on DERBY-6533:
--------------------------------------

I ran NsTest again on the 8-core machine. There were several new errors, the test died after
157 minutes, and my connection to the machine was broken. Here are the errors I saw:

1) 1 assertion failure when looking up the sequence generator

2) 1 "too much contention" error on the sequence generator

3) 1 IndexArrayOutOfBoundsException when deleting a row from the table

4) 306 lock timeouts

5) 1032 NPEs in the test

6) 46720 "no current connection" errors

I will attach the report.

> Right now NsTest produces an enormous log file. This may be useful for tracking down
some errors. However, this can also make it hard to find the signal in the noise. It would
be good to turn off the chatty diagnostics which report the result of every insert, update,
delete, and select. A summary at the end may be good enough, including a summary of the number
of times each kind of error (SQLState) was seen. While I'm in there, I plan to make other
smallish changes.
