Michael Poindexter commented on LUCENE-4848:
--------------------------------------------
No problem, I'll produce a patch against trunk that just changes the existing
directory implementations as little as possible.
Two questions:
1.) Since this changes the file writing behavior for NIOFSDirectory and
MMapDirectory (writes can now throw a ClosedChannelException if the thread is
interrupted, where I believe they couldn't before) should the changes be
controllable via a flag? Or should I just not change how writes are done for
these two classes (since it shouldn't be necessary to delete a file while it is
open for write, only if it is open read)
2.) I was using a Path instead of a File internally to represent the directory
location. This is somewhat nice in that it works with the Java 7 pluggable
filesystems implementation (i.e. to zip up an index one could just use the zip
filesystem provider with a directory and then do a Directory.copyTo). I assume
you want to not add a dependency on using a Path since that would change the
return type of FSDirectory.getDirectory()?

>
> 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.
