Server not able to get address raising no attribute 'cfg_addr'

[shuoli84]

My setup:

Gunicorn + gevent_socketio + django

Started the server by:

gunicorn --env DJANGO_SETTINGS_MODULE=linbang.settings -c gunicorn_config.py --error-logfile -  linbang.wsgi:application

In gunicorn_config.py:

bind = '0.0.0.0:8000'
max_requests = 10000
worker_class = 'socketio.sgunicorn.GeventSocketIOWorker'
workers = 5

def post_fork(server, worker):
import pymysql
pymysql.install_as_MySQLdb()

I'm having the same issue when stress testing simple test app.

AttributeError: 'socket' object has no attribute 'cfg_addr'

I see that you use workers = 5 in your config file.
Does it work without problems ? I was having errors when workers was set to > 1, despite the fact that I was using websocket transport (so this wasn't issue of long-polling and different processes for each request).

I am having the same issue.

Save the following snippet as geventworker.py

from socketio.sgunicorn import GeventSocketIOWorker

class MyGeventSocketIOWorker(GeventSocketIOWorker):
    policy_server = False

and launch your app with

 gunicorn --worker-class geventworker.MyGeventSocketIOWorker wsgy:app

as noted here, using earlier gunicorn versions may work for you.

pip uninstall gunicorn
pip install gunicorn==18.0

I just committed a fix, which will make it work with newer version of gunicorn. The merge is pending.
ant9000 workaround will help but better solution is to adapt to gunicorn changes.

[arnuschky]

Merge will stay pending forever as this project is missing a maintainer.

BTW, I can confirm that the workaround of @ant9000 works fine. Alternatively, you can also set the environment variable POLICY_SERVER to false.

Cool. I will stay with my forked branch then :)
