Description

« Hide

When deleted documents are flushed using IndexReader.flush() the delCount in SegmentInfo is updated based on the current value and SegmentReader.pendingDeleteCount (introduced by ~~LUCENE-1267~~). It seems that pendingDeleteCount is not reset after the commit, which means after a second flush() or close() of an index reader the delCount in SegmentInfo is incorrect. A subsequent IndexReader.open() call will fail with an error when assertions are enabled. E.g.:

java.lang.AssertionError: delete count mismatch: info=3 vs BitVector=2
at org.apache.lucene.index.SegmentReader.loadDeletedDocs(SegmentReader.java:405)
[...]
