Subject [jira] Commented: (LUCENE-672) new merge policy
Date Sat, 16 Sep 2006 03:47:23 GMT
    [ http://issues.apache.org/jira/browse/LUCENE-672?page=comments#action_12435174 ] 
            
Ning Li commented on LUCENE-672:
--------------------------------

A small fix named KeepDocCount0Segment.Sept15.patch is attached to LUCENE-565 (can't attach
here).

In mergeSegments(...), if the doc count of a merged segment is 0, it is not added to the index
(it should be properly cleaned up). Before LUCENE-672, a merged segment was always added to
the index. The use of mergeSegments(...) in, e.g. addIndexes(Directory[]), assumed that behaviour.
For code simplicity, this fix restores the old behaviour that a merged segment is always added
to the index. This does NOT break any of the good properties of the new merge policy.

TestIndexWriterMergePolicy is slightly modified to fix a bug and to check that segments are
probably cleaned up. The patch passes all the tests.
