Subject [jira] Commented: (LUCENE-2476) Constructor of IndexWriter let's runtime exceptions pop up, while keeping the writeLock obtained
Date Tue, 25 May 2010 16:04:26 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12871218#action_12871218

Cservenak, Tamas commented on LUCENE-2476:
------------------------------------------

Just to confirm this patch as fix.

The patch applied to 3.0.1 (I had to do it manually, since I believe this patch is against
trunk, not 3.0.1) does fix my problem. The IndexWriter is now successfully recreated and my
UT does recover just fine from corrupted indexes.

obtained.
> The init method in IndexWriter catches IOException only (I got NegativeArraySize by reading
up a _corrupt_ index), and now, there is no way to recover, since the writeLock will be kept
obtained. Moreover, I don't have IndexWriter instance either, to "grab" the lock somehow,
since the init() method is called from IndexWriter constructor.
> Either broaden the catch to all exceptions, or at least provide some circumvention to
clear up. In my case, I'd like to "fallback", just delete the corrupted index from disk and
recreate it, but it is impossible, since the LOCK_HELD NativeFSLockFactory's entry about obtained
WriteLock is _never_ cleaned out and is no (at least apparent) way to clean it out forcibly.
I can't create new IndexWriter, since it will always fail with LockObtainFailedException.
