Michael Poindexter commented on LUCENE-4848:
--------------------------------------------
Thanks for the demonstration Uwe! It was very helpful as I misunderstood our
earlier conversation and was attempting to change the internals of FSDirectory
to use Path (instead of File) while keeping the public interface the same
(actually, I was done, but waiting for the tests to run before attaching the
patch, so your timing was perfect :) )
I've attached a patch in the same spirit as your MMapDirectory patch that makes
some minor changes to FSDirectory to allow different FSIndexInput and
FSIndexOutput subclasses that use different methods of accessing the file (i.e.
RandomAccessFile vs. FileChannel). It updates MMapDirectory, SimpleFSDirectory
and NIOFSDirectory to use appropriate subclasses, and adds a new
AsyncFSDirectory class.

> Project: Lucene - Core
> Issue Type: Task
> Reporter: Michael Poindexter
> Assignee: Uwe Schindler
> Priority: Minor
> Attachments: jdk7directory.zip, LUCENE-4848-MMapDirectory.patch,
> LUCENE-4848.patch
>
>
> 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.
