Aleksandr Savonin updated FLINK-39941:
--------------------------------------
Description:
The weekly CI Python test job fails on the v4.0 branch in the py38-cython tox
environment (Python 3.8).
[https://github.com/apache/flink-connector-kafka/actions/runs/27484280508/job/81237466038]
This is toolchain drift, not a connector code change. The tox Python
environments bootstrap pip unpinned (is not fixed). Modern pip no longer
supports Python 3.8, even its own code uses a Python 3.10+ feature, so pip
crashes on import under Python 3.8 and cannot install apache-flink.
Options:
a) drop 3.8 (however, Flink 2.0 supports Python 3.8)
b) fix the broken toolchain
