Eduard Tudenhoefner updated CASSANDRA-15573:
--------------------------------------------
Description:
Python 3.8 renamed sre_parse.Pattern to sre_parse.State (see
https://bugs.python.org/issue34681 and corresponding pull request
https://github.com/python/cpython/pull/9310)
So when executing cqlsh with Python 3.8, it throws error:
{code}
Traceback (most recent call last):

Added a Python 3.8 compatible SafeScanner implementation. Note that the changes
from CASSANDRA-15659 are required in order to verify that the issue is fixed.
