Add CID to the uwsgi proxy while running django in production

[anuj9196]

Using uWSGI in the production to run application inside the docker container.

I have added the following log format

UWSGI_LOG_FORMAT='[pid: %(pid)|app: %(wid)|req: %(rlen)/%(total_requests)] %(addr) () {%(vars) vars in %(cl) bytes} [%(ltime)] %(method) %(uri) => generated %(size) bytes in %(msecs) msecs (%(protocol)) %(headers) (cid:%(var.CID))'

and crated a uwsgi wrapper middleware

from cid.locals import get_cid


class UWSGICIDMiddleware:
    def __init__(self, app):
        self.app = app

    def __call__(self, environ, start_response):
        try:
            import uwsgi
            cid = (
                    environ.get("HTTP_X_CORRELATION_ID") or
                    environ.get("HTTP_X_REQUEST_ID") or
                    environ.get("REQUEST_ID") or
                    get_cid() or
                    "-"  # fallback
            )
            uwsgi.set_logvar("CID", cid)
        except ImportError:
            pass
        return self.app(environ, start_response)

which we are using in the wsgi.py configuration as

import os

from django.core.wsgi import get_wsgi_application

from tools.proxy.uwsgi import UWSGICIDMiddleware

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'feedal.settings')

application = UWSGICIDMiddleware(get_wsgi_application())

However, the log statement does not contain the cid, but the application has cid added to every log
