Subject [jira] [Commented] (LUCENE-3139) LuceneTestCase.afterClass does not print enough information if a temp-test-dir fails to delete
Date Tue, 24 May 2011 14:55:48 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13038601#comment-13038601
] 

Robert Muir commented on LUCENE-3139:
-------------------------------------

some tests are still problematic, at least on windows... I think perhaps some of the crazier
ones like DiskFull, TestCrash, anything that has to disable MockDirectoryWrappers's checks
because they must create corrupt indexes or other scary things.

> I've hit an exception from LTC.afterClass when _TestUtil.rmDir failed (on write.lock,
as if some test did not release resources). However, I had no idea which test caused that
(i.e. opened the temp directory and did not release resources).
> I think we should do the following:
> * Track in LTC a map from dirName -> StackTraceElement
> * In afterClass if _TestUtil.rmDir fails, print the STE of that particular dir, so we
know where was this directory created from
> * Make tempDirs private and create accessor method, so that we control the inserts to
this map (today the Set is updated by LTC, _TestUtils and TestBackwards !)
