[jira] [Created] (COUCHDB-3055) _changes queries using non existent (moved) shard may rewind from zero

ILYA created COUCHDB-3055:
-----------------------------

             Summary: _changes queries using non existent (moved) shard may rewind from zero
                 Key: COUCHDB-3055
                 URL: https://issues.apache.org/jira/browse/COUCHDB-3055
             Project: CouchDB
          Issue Type: Bug
            Reporter: ILYA


The call to unpack the since sequence for _changes incorrectly filtered
the value for any shard that didn't exist. This means that any shard
that was moved ended up requiring a complete rescan which is a bug. This
just sets the update sequence to the range of the shard being replaced
rather than zero.
