[jira] Resolved: (LUCENE-2809) IndexWriter.numDocs doesn't take into account applied but not flushed deletes

["Michael McCandless (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-2809?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael McCandless resolved LUCENE-2809.
----------------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 2.9.5)
                       (was: 3.0.4)
                       (was: 3.1)

Let's just resolve it (against 3.1/4.0) and if we do another 2.9/3.0 release we can reopen for backport.

> The javadoc states that buffered deletes are not taken into account and so you must call commit first.
> But, if you do that, and you're using CMS, and you're unlucky enough to have a background merge commit just after you call commit but before you call .numDocs, you can still get a wrong count back.
> The fix is trivial -- numDocs should also consult any pooled readers for their current del count.
> This is causing an intermittent failure in the new TestNRTThreads.
