no access log when gunicorn work class as tornado

[nnsay]

I has a gunicorn config as below:

bind = '127.0.0.1:3000'
workers = 2
worker_class = 'tornado'
proc_name = 'dome'
loglevel = 'debug'
pidfile = './gunicorn.pid'
accesslog = './log/access.log'
errorlog = './log/error.log'
raw_env = 'env=dev'

I do not find any access log when debugging. But I change worker_class as gevent, the access log is work! Why no access log when the gunicorn work class been set tornado ?

maybe tornado is overriding the log config? I will check

yeah, i have the same issue. basically, i cannot overwrite the default tornado.access logger in gunicorn_logconfig.ini

I couldn't get tornado worker work with gunicorn master and tornado 4.4.2 by the way:

ERROR:tornado.application:Uncaught exception

Is there any ETA for fix of this issue? or any workaround for the same.

I imagine this would involve the following changes:

• [ ] tell tornado to not setup conflicting logging, e.g. tornado.options.logging = "none"
• [ ] patch tornado.wsgi.WSGIContainer to call our handler
• [ ] patch tornado.web.Application to call our handler
• [ ] patch environ (because we add non-rfc3875 keys such as RAW_URI and glogging will assert they are there)
• [ ] forward size, request and response headers to our logging <= tricky without overriding internals / restricting supported versions

For reference, this is what I did to mock up access logs for the tornado worker for my testing purposes: https://github.com/benoitc/gunicorn/pull/3201/files#diff-233ae0d57e7947065c3b18f680f31643c2b97dfefa2665ce2d3afcceaab773e7
