Stefania commented on CASSANDRA-11850:
--------------------------------------
2.1 tests are fine but in 2.2+ we have some behavioral changes in the driver
that cause problems, mostly related to utf-8 encoding and
[PYTHON-458|https://datastax-oss.atlassian.net/browse/PYTHON-458] /
CASSANDRA-10686.
Some fixes went into the patches linked above, whilst the fixes in the dtest
code are [here|https://github.com/stef1927/cassandra-dtest/tree/11850]. I've
relaunched the tests.
[~pauloricardomg], given that PYTHON-458 is now available, are we still
expecting an operation timeout and schema mismatch warning in
[{{test_refresh_schema_on_timeout_error}}|http://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-11850-cqlsh-2.2-cqlsh-tests/lastCompletedBuild/cython=no/testReport/cqlsh_tests.cqlsh_tests/TestCqlsh/test_refresh_schema_on_timeout_error/]?
I added the following in cqlsh
[{{perform_simple_stement}}|https://github.com/stef1927/cassandra/commit/ba02cd1b96e329b533141cf78c43eb960e5d4d61#diff-1cce67f7d76864f07aaf4d986d6fc051R1256]
but {{future.is_schema_agreed}} is always true (I think the driver refreshes
the metadata before returning the statement result):
{code}
future = self.session.execute_async(statement, trace=self.tracing_enabled)
result = future.result()
if not future.is_schema_agreed:
self.refresh_schema_metadata_best_effort()
{code}
> cannot use cql since upgrading python to 2.7.11+
