[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=13607604#comment-13607604 ]

Dawid Weiss commented on LUCENE-4848:
-------------------------------------

Yep, ok I get you. They are all daemon threads, so we could just ignore these. But there were a good few cases when daemon threads were forked that led to discovering odd causes so I'd rather keep those.

Seems like there's no other way indeed. I still have a suggestion of keeping the static initializer but moving the common code to that "quick patch" class to keep it in a single location. You can also detect those threads by returning a thread class that implements some internal interface, doesn't have to be by-name (and I'd actually name them legibly: "asyncio-%d" or something). :)

> 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.
