GeventSocketIOWorker has no attribute 'socket'

问题

I need to run Django application using gunicorn. I read documentation, and I think I set up everything like I should, but when I run

gunicorn --worker-class socketio.sgunicorn.GeventSocketIOWorker app.wsgi:application

I get following error message

2013-02-01 18:25:17 [25394] [INFO] Booting worker with pid: 25394
2013-02-01 18:25:18 [25394] [ERROR] Exception in worker process:

If I run it with django_socketio, everything works fine, I must miss something really important.

Thank you for your help

Seems to be a problem with gunicorn>0.17, see issue #122. For me it's working with the version 0.16.1 of gunicorn.

pip install gunicorn==0.16.1

回答2:

It's possible that installing gevent-socketio 0.3.6 might fix this without having to revert gunicorn for some cases. I had 0.3.5-rc2 and upgrading fixed this issue for me (NOTE: this was not in django, but it worked.)

pip install gevent-socketio==0.3.6

Caused by this change in gunicorn. https://github.com/benoitc/gunicorn/commit/9a83d719b23fe28667a9c76bac25ba66651f8ccf

Previously the sockets used for gevent worker came from gunicorn socket now they wrap gevent cooperative sockets. So reverting to an older version of gunicorn is not good idea. May be disable Flash Policy Server that will disable this check.
