Subject [jira] [Commented] (LUCENE-4649) kill ThreadInterruptedException
Date Tue, 01 Jan 2013 12:06:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13541625#comment-13541625

Michael McCandless commented on LUCENE-4649:
--------------------------------------------

OK I see, so the big problem is we are throwing our own exc (ThreadInterruptedException) but
*failing* to set the interrupt bit?  Ie this is a violation of the protocol (we can only clear
the interrupt status if we throw the true, checked InterruptedException).  I agree with that.

But, I don't see why we should pretend that you hit an IOException when in fact we were interrupted?
 That seems worse than throwing ThreadInterruptedExc.

> 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.
