Michael Semb Wever commented on CASSANDRA-19467:
------------------------------------------------
First up the {{.build/run-python-dtests.sh}} isn't used to run cqlsh tests, and
AFAIK the python dtests should all remain python >=3.8 from 5.0 up.
The scripts that run the cqlsh tests ({{pylib/cqlshlib/test/run_cqlsh.py}}) are
{{.build/run-tests.sh}} and {{.build/docker/run-tests.sh}}
The former doesn't have any python version validation in it. (It should!)
It sets the python_version here:
https://github.com/apache/cassandra/blob/cassandra-5.0/.build/docker/run-tests.sh#L225
But it won't work for 3.6 and 3.7 because these pyenv are not available in the
image:
https://github.com/apache/cassandra/blob/cassandra-5.0/.build/docker/ubuntu2004_test.docker#L50-L60
> Deprecate Python 3.7 and earlier, but allow cqlsh to run with Python 3.6+

> In 4.0, we introduced Python 3.6 support. In CASSANDRA-19245, for the 5.0
> release, we dropped Python 3.6 and 3.7 support since Python 3.8 was the
> minimum supported version for version 3.29.0 of the Python driver, which we
> needed to support vectors. Unfortunately, that may break existing users of
> RHEL 7, which natively only supports Python 3.6.
> We should deprecate Python 3.6-3.7 (which are all either EOL or will be soon)
> and mention this in NEWS.txt/appropriate warnings at {{cqlsh}} startup, but
> we don't need to have cqlsh refuse to start entirely with 3.6-3.7 until our
> 6.0 release.
