Improve test debuggability through ant
--------------------------------------
Key: LUCENE-2807
URL: https://issues.apache.org/jira/browse/LUCENE-2807
Project: Lucene - Java
Issue Type: Improvement
Components: Tests
Reporter: Michael McCandless
Fix For: 4.0
Some small improvements would go a long ways...
When trying to debug an intermittent fail, I usually run w/
-Dtests.verbose=true and w/ many iters. But because the formatter buffers this
can hit OOME, so maybe we make an unbuffered formatter. Also, it'd be nice if
we could have the formatter discard output for a given iter if there was no
failure, and I think the iters should stop as soon as a failure is hit.
Maybe somehow we make a new tests.mode that would switch on these behaviours?
Unbuffered formatter is also vital when debugging a deadlock...
