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 07:45:12 GMT


Dawid Weiss commented on LUCENE-4510:

Oh, forgot -- both props mentioned above are from randomized testing package so you'd have
to add them to common-build.xml and pass them to <junit4:junit4> task. We could probably
just replace all the props with a propertyset based on regexp so that all tests.* properties
are passed automatically... but then it wouldn't be so explicit so maybe it's actually better
the way it is.

> 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...).
