When IndexReader.reopen is called, old reader is not properly closed
--------------------------------------------------------------------
Key: SOLR-1808
URL: https://issues.apache.org/jira/browse/SOLR-1808
Project: Solr
Issue Type: Bug
Components: search
Affects Versions: 1.4
Reporter: John Wang
According to Lucene documentation:
"If the index has not changed since this instance was (re)opened, then this
call is a NOOP and returns this instance. Otherwise, a new instance is
returned. The old instance is not closed and remains usable."
In SolrCore.java:
if (newestSearcher != null && solrConfig.reopenReaders
&& indexDirFile.equals(newIndexDirFile)) {
IndexReader currentReader = newestSearcher.get().getReader();
IndexReader newReader = currentReader.reopen();
if (newReader == currentReader) {
currentReader.incRef();
}
tmp = new SolrIndexSearcher(this, schema, "main", newReader, true,
true);
}
When currentReader!=newReader, currentReader seems to be leaking.
