[jira] [Commented] (LUCENE-3207) CustomScoreQuery calls weight() where it should call createWeight()

["Robert Muir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-3207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13050263#comment-13050263 ] 

Robert Muir commented on LUCENE-3207:
-------------------------------------

as an explanation, this causes this query to call sumOfSquaredWeights + queryNorm + normalize() twice.

the reason it doesnt cause any tests to fail in trunk is this:
in trunk sumOfSquaredWeights is not really a getter, its also a setter:
{noformat}
    @Override
    public float sumOfSquaredWeights() {
      queryWeight = idf * getBoost();             // compute query weight
      return queryWeight * queryWeight;           // square it
    }
{noformat}

in my patch on LUCENE-3174, my sumOfSquaredWeights returns queryWeight * queryWeight, but doesn't reset any state.
so you end out normalizing twice and thats why the test failed on the branch.
