[jira] Commented: (LUCENE-1474) Incorrect SegmentInfo.delCount when
IndexReader.flush() is used
[ https://issues.apache.org/jira/browse/LUCENE-1474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719435#action_12719435 ]

Hi Michael,
The index that Erik was working with contained segments created with a pre-2.4.1 version of Lucene, so we don't believe this is a regression.

> 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)
> [...]
