Subject [jira] Commented: (CASSANDRA-357) CompareSubcolumnsWith= has no effect
Date Mon, 10 Aug 2009 20:18:14 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741528#action_12741528
] 

Jonathan Ellis commented on CASSANDRA-357:
------------------------------------------

I added this to the patched test_time_uuid in test_server.py:

        p = SlicePredicate(slice_range=SliceRange(L[2].bytes, '', True, 1))
        column_parent = ColumnParent('Super4', 'sc1')
        slice = [result.column
                 for result in client.get_slice('Keyspace2', 'key1', column_parent, p, ConsistencyLevel.ONE)]
        assert slice == [Column(L[2].bytes, 'value2', 2)], slice

this passes.  I'm not sure how this differs from yours.
