Date Wed, 02 Jan 2013 15:12:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13542168#comment-13542168

Robert Muir commented on LUCENE-4649:
-------------------------------------

Really as part of this issue we should re-enable mmap/niofs for TestIndexWriter.testThreadInterruptDeadlock()
?

Its like if we havent fixed that case (LUCENE-4638), then we havent fixed this issue correctly...

> the way we currently do this is bogus.
> For example in FSDirectory's fsync, i think we should instead:
> {noformat}
> } catch (InterruptedException ie) {
> - throw new ThreadInterruptedException(ie);
> + Thread.currentThread().interrupt(); // restore status
> + IOException e = new java.io.InterruptedIOException("fsync() interrupted");
> + e.initCause(ie);
> + throw e;
> {noformat}
> and crazy code in IndexWriter etc that catches ThreadInterruptedExc just to restore status
should be removed. 
> Instead the guy doing the catch (InterruptedException) should do the right thing.
