[jira] Commented: (LUCENE-2536) Rollback doesn't preserve integrity of original index

["Mark Harwood (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-2536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12887757#action_12887757 ] 

Mark Harwood commented on LUCENE-2536:
--------------------------------------

Looks like on the "close" call IndexWriter is flushing a superfluous ".del" file of buffered deletes.

>          Issue Type: Bug
>          Components: Index
>    Affects Versions: 3.0.2

> After several "updateDocuments" calls a rollback call does not return the index to the prior state.
> This seems to occur if the number of updates exceeds the RAM buffer size i.e. when some flushing of updates occurs.
> Test fails in Lucene 2.4, 2.9, 3.0.1 and 3.0.2
> JUnit to follow.
