[jira] [Commented] (LUCENE-4848) Fix Directory implementations to use NIO2 APIs

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/LUCENE-4848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13607609#comment-13607609 ]

Michael Poindexter commented on LUCENE-4848:
--------------------------------------------

bq. Have you looked at WindowsDirectory.cpp in the "misc" module? It does overlapped IO but still in sync.

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.

> 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.
