diff correcting the problem

> Key: SOLR-2860
> URL: https://issues.apache.org/jira/browse/SOLR-2860
> Project: Solr
> Issue Type: Bug
> Components: SearchComponents - other
> Reporter: Aaron Beppu
> Priority: Trivial
> Attachments: trackingwriters.patch
>
>
> This appears to be a simple copy/paste error, where someone attempted to copy
> the code for tracking open/close counts on SolrIndexSearcher, and use it to
> track open/close counts on SolrIndexWriter, but didn't update all of the
> variables. In particular :
> -- the "startTrackingWriters()" method sets the values of numOpens and
> numCloses, not numWriterOpens and numWriterCloses
> -- because in "beforeClassSolrTestCase()", startTrackingWriters() is called
> after startTrackingSearchers(), this means that the "start" counts referenced
> by startTrackingSearchers can be incorrect. This can cause
> "endTrackingSearchers()" to report nonsensical (e.g. negative) open or close
> counts in test cases.
> -- inside "endTrackingWriters()", the test condition for detecting when
> writers have been opened but not closed uses numOpens / numCloses, even
> though the error message it logs uses numWriterOpens / numWriterCloses.
