    Description

      The last time they passed in CI was April 30. All other python (and pypy) versions are fine.

      The first failure was on May 10. CI backtracking show the tests failing with every commit after https://github.com/mongodb/mongo-python-driver/commit/bac6761a4304d48298e076a37c649d80619be6aa. The next commit doesn't seem like it could have any affect on these tests. The only package dependencies that seemed to change were transient dependencies:

      • six changed from 1.15.0 to 1.16.0
      • attrs changed from 20.3.0 to 21.1.0

      The last version of attrs that claims support for Python 3.4 is 19.3.0.

      With successful tests we get log output like:

       [2021/05/04 01:06:56.956] OK
      

      Failing tests provide no such log output. I suspect there is an import failure happening in the ssl machinery that we are catching and ignoring, falling back to python's built-in ssl module that does not support OCSP.
