Subject [jira] Updated: (LUCENE-1709) Parallelize Tests
Date Fri, 26 Mar 2010 17:50:31 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-1709?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated LUCENE-1709:
--------------------------------

    Attachment: LUCENE-1709.patch

attached is an updated patch, run the same commands before applying the patch:
{noformat}
svn move solr/src/test/org/apache/solr/SolrJUnitResultFormatter.java lucene/src/test/org/apache/lucene/util/LuceneJUnitResultFormatter.java
svn copy lucene/src/test/org/apache/lucene/util/LuceneJUnitResultFormatter.java lucene/backwards/src/test/org/apache/lucene/util/LuceneJUnitResultFormatter.java
{noformat}

Mark fixed the interleaved output here, so this is good.
But, there is a problem in that we change java.io.tmpdir in tests, so we cannot use it
for the lock file. So if we fix tests to only use "tempDir", then we are ok with the formatter,
as it can just use java.io.tmpdir for its lock file.

> The Lucene tests can be parallelized to make for a faster testing system.  
> This task from ANT can be used: http://ant.apache.org/manual/CoreTasks/parallel.html

> 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.
