Subject [jira] Updated: (LUCENE-821) single norm file still uses up descriptors
Date Sat, 03 Mar 2007 18:44:50 GMT


Yonik Seeley updated LUCENE-821:

    Attachment: norms.patch

Attaching patch.


- Only open a single IndexInput for the .nrm file and reuse it for all
norms sharing that file in the segment.  No clone is needed since
only a single norm is read at any time.

- close norms when no longer needed (idea from Michael)

- removed extra IndexInput clone() when reading the norms... why was this there originally?

descriptor usage.
> The .nrm file is opened once for each field with norms in the index segment.
