Subject [jira] [Commented] (LUCENE-4848) Fix Directory implementations to use NIO2 APIs
Date Wed, 20 Mar 2013 13:49:15 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13607612#comment-13607612

Yep, I looked at it. I don't know about anyone else, but I strongly prefer not to use native
code if I can help it (makes deployment more of a pain since you need the right binary for
your architecture, possibility of native resource leaks that are hard to debug). If there
exists a Java API I'd much rather use that.

Exactly: thats why if this AsyncDirectory that waits doesn't have too much overhead, it would
be a nice replacement for that jni crap.

But we can probably get all of this in lucene faster if we break the issue up a little bit
:)

> I have implemented 3 Directory subclasses using NIO2 API's (available on JDK7).  These
may be suitable for inclusion in a Lucene contrib module.
> See the mailing list at http://lucene.markmail.org/thread/lrv7miivzmjm3ml5 for more details
about this code and the advantages it provides.
> The code is attached as a zip to this issue.  I'll be happy to make any changes requested.
 I've included some minimal smoke tests, but any help in how to use the normal Lucene tests
to perform more thorough testing would be appreciated.
