Subject [jira] [Commented] (LUCENE-4649) kill ThreadInterruptedException
Date Wed, 02 Jan 2013 15:26:13 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13542178#comment-13542178
] 

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

the main bug in the current patch is how we swallow things in IndexWriter.close

this whole thing should act like IOUtils.close() and have a 'Exception priorException'.
We can check the interrupt bit to determine that we should not wait when calling finishMerges(),
but thats it!

we should try to close everything down and ensure that prior exception (ClosedByInterrupt,
InterruptedIO, Runtime, whatever the hell it is) gets thrown too.

> 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.
