Brad Schoening updated CASSANDRA-19603:
---------------------------------------
Description:
The asyncore module is deprecated and has been removed in Python 3.12. To
support 3.12, we need to upgrade to use asyncio.
DEBUG test_cqlsh:run_cqlsh.py:194 read ' from cqlshlib.cqlshmain import
main\r\n File "pylib/cqlshlib/cqlshmain.py", line 37, in <module>\r\n from
cassandra.cluster import Cluster\r\n File

line 173, in <module>\r\ncassandra.DependencyException: Unable to load a
default connection class\r\nThe following exceptions were observed: \r\n - The
C extension needed to use libev was not found. This probably means that you
didn\'t have the required build dependencies when installing the driver. See
[http://datastax.github.io/python-driver/installation.html#c-extensions] for
instructions on installing build dependencies and building the C extension.\r\n
- Unable to import asyncore module. Note that this module has been removed in
Python 3.12 so when using the driver with this version (or anything newer) you
will need to use one of the other event loop implementations.\r\n' from subproc
