Michael McCandless updated LUCENE-2828: --------------------------------------- Fix Version/s: 3.0.4 2.9.5 > SimilarityDelegator broke back-compat for subclasses overriding lengthNorm > -------------------------------------------------------------------------- > > Key: LUCENE-2828 > URL: https://issues.apache.org/jira/browse/LUCENE-2828 > Project: Lucene - Java > Issue Type: Bug > Affects Versions: 2.9, 2.9.1, 2.9.2, 2.9.3, 2.9.4, 3.0, 3.0.1, 3.0.2, 3.0.3 > Reporter: Michael McCandless > Fix For: 2.9.5, 3.0.4 > > Attachments: LUCENE-2828.patch > > > In LUCENE-1420, we added Similarity.computeNorm to let the norm computation > have access to the raw information (length, boost, etc.). > But this class broke back compat with SimilarityDelegator. We did add > computeNorm there, but, it's impl just forwards to the delegee's computeNorm. > In the case where a subclass of SimilarityDelegator overrides lengthNorm, > that method will no longer be invoked. > Not quite sure how to fix this since, somehow, we have to determine whether > the delegee's impl of computeNorm should be favored over the subclasses impl > of the "legacy" lengthNorm. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
