Subject [jira] [Commented] (LUCENE-4510) when a test's heart beats it should also throw up (dump stack of all threads)
Date Sat, 27 Oct 2012 12:53:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13485423#comment-13485423

I vaguely remember people on the mailing list expressed concerns even about the heartbeat
messages so throwing stack traces at everyone would be probably a bit too much.

But we have tests totally hanging and taking minutes of time. So I think their concerns can
wait in line!

On the other hand if we like the test hangs and want to keep them :)

> We've had numerous cases where tests were hung but the "operator" of that particular
Jenkins instance struggles to properly get a stack dump for all threads and eg accidentally
kills the process instead (rather awful that the same powerful tool "kill" can be used to
get stack traces and to destroy the process...).
> Is there some way the test infra could do this for us, eg when it prints the HEARTBEAT
message?
