Hoss Man updated SOLR-3548:
---------------------------
Attachment: SOLR-3548.patch
it took a lot longer then i though, but here is a patch that adds QueryUtils
checking against (at least one of) the Query objects produced by every default
QParser and ValueSourceParser. It includes a future proofing "testCoverage"
that sets a bit informing an AfterClass method to assert that all of the
default parsers were tested so we don't risk this probably again the next time
someone adds a new parsers.
Currently 4 methods are failing, indicating the following problems...
* strdist func - identical query strings don't produce equals() queries
* join qparser - clone w/diff boost still has equals hashCode
* bbox qparser - clone w/diff boost still has equals hashCode
* geofilt qparser - clone w/diff boost still has equals hashCode
the hashCode equality isn't the end of the world, but it suggests a really poor
hashCode impl (that evidently doesn't call super since Query.hashCode already
handles the boost)
> some queries produced by built in QParsers are not .equals() to themselves

> working on SOLR-3522 i discovered that in some cases Solr is producing
> queries that aren't equals to themselves, so they can't be cached.
> So far the only observed problem is in func strdist, but i want to make sure
> we have an exhaustive test of this in case there are others
