Subject [jira] [Commented] (LUCENE-3310) FuzzyAttribute ignores min similarity when generating at hashcode(), toString() and equals() methods
Date Sat, 30 Jul 2011 18:42:11 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13073228#comment-13073228

Adriano Crestani commented on LUCENE-3310:
------------------------------------------

Good point Michael! At least they shouldn't use mutable values in their hashcode. The only
reason I remember to implement hashcode in qp attributes was because Lucene attributes (CharTermAttributeImpl,
OffsetAttributeImpl etc) do the same.

It sounds like all attribute impls shouldn't be doing that and we should fix. Luckily, today,
nowhere in Lucene code we use Attribute instances as key or in sets, that is why we probably
never hit any problems. However, users may be hitting problems because of that. I think we
should fix it as soon as possible as it seems very critical.

Please, let me know if I am missing something.
