Subject [jira] [Commented] (LUCENE-4252) Detect/Fail tests when they leak RAM in static fields
Date Wed, 25 Jul 2012 12:40:35 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13422203#comment-13422203

Robert Muir commented on LUCENE-4252:
-------------------------------------

I already set this threshold as low as 512KB and was fixing the minor leaks last night...
lemme update the patch (still at 10MB) with my idea to catch static initializers.

> We run our junit tests without firing up a JVM each time.
> But some tests initialize lots of stuff in @BeforeClass and don't properly null it out
in an @AfterClass, which can cause a subsequent test in the same JVM to OOM, which is difficult
to debug.
> Inspiration for this was me committing Mike's cool TestPostingsFormat, which forgot to
do this: then we were seeing OOMs in several jenkins runs.
> We should try to detect these leaks in LuceneTestCase with RAMUsageEstimator and fail
the test.
