Robert Muir updated LUCENE-1709:
--------------------------------
Attachment: LUCENE-1709.patch
attached is a patch, before applying it you must do this:
{noformat}
svn move solr/src/test/org/apache/solr/SolrJUnitResultFormatter.java
lucene/src/test/org/apache/lucene/util/LuceneJUnitResultFormatter.java
{noformat}
The formatter itself is really broken, the sync only makes the output work
within a single TestSuite.
We need some file-locking or similar to ensure it is really correct.
The patch does not do backwards in parallel (only core/contrib)
Also, there is the TEMP_DIR problem i mentioned, which i haven't addressed here.

> I'd love to see a clean solution here (the tests are embarrassingly
> parallelizable, and we all have machines with good concurrency these
> days)... I have a rather hacked up solution now, that uses
> "-Dtestpackage=XXX" to split the tests up.
> Ideally I would be able to say "use N threads" and it'd do the right
> thing... like the -j flag to make.
