Description of problem: there is an incompatibility between the following RPMS: python3-gevent-1.2.2-4.el8.x86_64 (from Appstream RHEL-8) python3-gunicorn-20.0.4-2.el8.noarch (from EPEL-8) in gunicorn you can define a worker of type gevent. however that version of gunicorn requires gevent > 1.4, which is higher than the version provided in RHEL-8. the check is embedded in gunicorn code (/usr/lib/python3.6/site-packages/gunicorn/workers/ggevent.py): from pkg_resources import parse_version if parse_version(gevent.__version__) < parse_version('1.4'): raise RuntimeError("gevent worker requires gevent 1.4 or higher") Version-Release number of selected component (if applicable): 20.0.4-2.el8 How reproducible: start any application under gunicorn with gevent worker class, ex.: gunicorn --bind=0.0.0.0:8000 --workers=1 --worker-class=gevent "my_project:create_app()" will cause: RuntimeError: gevent worker requires gevent 1.4 or higher
I think I've narrowed down the problem here. The upstream project added a runtime check for gevent 1.4 in gunicorn 20.0.0 [0][1]. However, they didn't enforce this minimum version at install time in setup.py until gunicorn 20.1.0, which is also when they added tests to ensure the different workers are importable [2][3]. This resulted in gunicorn 20.0.4 being added to EPEL 8, even though RHEL 8 only has gevent 1.2.2. We should be able to fix this by reverting the upstream changes for the gevent 1.4 runtime check. It's also worthwhile to backport the worker import checks at the same time. I've made this change [4], and it should show up in the epel-testing repo tonight.
