Dawid Weiss commented on LUCENE-4632:
-------------------------------------
I've just pushed 2.0.6 with this change.
> Restrict test-framework's write permissions more: Only allow write to per-JVM
> CWD and the clover.db.dir
> -------------------------------------------------------------------------------------------------------
>
> Key: LUCENE-4632
> URL: https://issues.apache.org/jira/browse/LUCENE-4632
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Fix For: 4.1, 5.0
>
>
> Currently we restring wrting to tests.tempDir after SOLR-4195, but it would
> be better to restrict more and only let child JVMs write to their working dir
> and not outside (and maybe corrumpt other JVMs).
> The problem with current setup is that the child JVM's policy file does not
> know the runner number nor the absolute working directory (it must be
> absolute and platform-specific with backslash/slash/... -> new
> File(".").getAbsolutePath().
> Dawid will release a new Junit4 package with a new sysprop passed to every
> child with its full CWD: junit4.childvm.cwd
> In that case the policy file would use this property (and the clover.db.dir)
> to allow write access and allow only read/execute access for the rest of the
> filesystem.
