Kishan Karunaratne updated CASSANDRA-9310:
------------------------------------------
Summary: Table change response returns as keyspace change response (was:
Table change event returns as keyspace change event)
> Table change response returns as keyspace change response
> ---------------------------------------------------------
>
> Key: CASSANDRA-9310
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9310
> Project: Cassandra
> Issue Type: Bug
> Environment: C* 1.2.19 and 2.0.14 | python-driver master (upcoming v.
> 2.6)
> Reporter: Kishan Karunaratne
>
> When an index is dropped, its existence is still persisted across the
> keyspace metadata. This happens because the response to drop the index from
> the metadata is never received, as a keyspace change response is
> (incorrectly) received by the driver instead of a table change response.
> {noformat}
> self.session.execute("CREATE TABLE %s (k int PRIMARY KEY, a int)" %
> self.table_name)
> ks_meta = self.cluster.metadata.keyspaces[self.keyspace_name]
> table_meta = ks_meta.tables[self.table_name]
> self.assertNotIn('a_idx', ks_meta.indexes)
> self.assertNotIn('b_idx', ks_meta.indexes)
> self.assertNotIn('a_idx', table_meta.indexes)
> self.assertNotIn('b_idx', table_meta.indexes)
> self.session.execute("CREATE INDEX a_idx ON %s (a)" % self.table_name)
> self.session.execute("ALTER TABLE %s ADD b int" % self.table_name)
> self.session.execute("CREATE INDEX b_idx ON %s (b)" % self.table_name)
> ks_meta = self.cluster.metadata.keyspaces[self.keyspace_name]
> table_meta = ks_meta.tables[self.table_name]
> self.assertIsInstance(ks_meta.indexes['a_idx'], IndexMetadata)
> self.assertIsInstance(ks_meta.indexes['b_idx'], IndexMetadata)
> self.assertIsInstance(table_meta.indexes['a_idx'], IndexMetadata)
> self.assertIsInstance(table_meta.indexes['b_idx'], IndexMetadata)
> # both indexes updated when index dropped
> self.session.execute("DROP INDEX a_idx")
> ks_meta = self.cluster.metadata.keyspaces[self.keyspace_name]
> table_meta = ks_meta.tables[self.table_name]
> self.assertNotIn('a_idx', ks_meta.indexes)
> {noformat}
> Output:
> {noformat}
> AssertionError: 'a_idx' unexpectedly found in {u'b_idx':
> <cassandra.metadata.IndexMetadata object at 0x7f2dd87d4590>, u'a_idx':
