Shai Erera updated LUCENE-3139:
-------------------------------
Attachment: LUCENE-3139.patch
Patch adds registerTempFile to LTC plus prints stack information if rmDir fails.
I think we should also fail the test if that happens?
> LuceneTestCase.afterClass does not print enough information if a
> temp-test-dir fails to delete

> 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 !)
