This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
The spec is unspecified as to what we should do when a database is opened with a different description than it was previously opened. I'd assume we'd want to update the description.
Fixed by http://dvcs.w3.org/hg/IndexedDB/rev/26e7d99ab935 It's a quite complicated checkin so please do check that things look good.
