Dawid Weiss commented on LUCENE-4332: ------------------------------------- bq. OK, cool: its something we never did before that I always thought should be done... Yes, I checked. Don't let this confuse you: {code} <junit4:junit4 dir="@{tempDir}" tempdir="@{tempDir}" {code} the "tempdir" is a temporary folder for all the extra files the runner needs (spills, event files, etc.), forked JVMs get their own subfolder. See the "isolateWorkingDirectories" parameter here; it's true by default so omitted: http://labs.carrotsearch.com/download/randomizedtesting/2.0.0-SNAPSHOT/docs/junit4-ant/Tasks/junit4.html I looked at the common-build.xml file though and I see only this: {code} <!-- Temporary directory in the cwd. --> <sysproperty key="tempDir" value="."/> {code} I was wrong then, the default 'java.io.tmpdir' is not overriden here and I think it should. I wrote a small test asking for a File.createTempFile and it did use a global temp (not good). > Integrate PiTest mutation coverage tool into build > -------------------------------------------------- > > Key: LUCENE-4332 > URL: https://issues.apache.org/jira/browse/LUCENE-4332 > Project: Lucene - Core > Issue Type: Improvement > Affects Versions: 4.1, 5.0 > Reporter: Greg Bowyer > Assignee: Greg Bowyer > Labels: build > Attachments: > LUCENE-4332-Integrate-PiTest-mutation-coverage-tool-into-build.patch, > LUCENE-4332-Integrate-PiTest-mutation-coverage-tool-into-build.patch > > > As discussed briefly on the mailing list, this patch is an attempt to > integrate the PiTest mutation coverage tool into the lucene build -- This message is automatically generated by JIRA.
