⁠Bug in gunicorn gevent worker

Showcase a bug in Gunicorn 19.4 in gevent worker when serving static files via whitenoise.

Automated docker image can be found here: https://hub.docker.com/r/slafs/whitenoise-test/⁠

⁠Steps to reproduce the bug

• With docker:

  • docker run -d --name gevent-worker -p 9999:9999 slafs/whitenoise-test

• Without docker (this can be observed on CentOS 6):

  • Clone the repo and go to whitenoise-gunicorn-gevent-bug dir.
  • Create a virtualenv and activate it.
  • Install dependencies in it (via pip install -r requirements.txt).
  • Run the app with gunicorn -b 0.0.0.0:9999 -k gevent app:app.

Now run curl http://127.0.0.1:9999/static/example > /dev/null several times.

You should observe transfer closed with xxxxx bytes remaining to read error messages from curl.
