Configure Gunicorn

[covracer]

Background and Links

• Gunicorn's default configuration
  • Makes searching for specific status codes hard
  • Doesn't surface the x-forwarded-for IP address, which is more likely to be the real client when load balancing is involved
  • Hides timed-out requests

Changes and Testing

• Log in a abbr=value format that's easy to search while somewhat concise
• Include some additional information
• Try to log details of timed out requests

Questions and Followup

• Better documentation of the log format
  • st STatus
  • lb Load Balancer IP address
  • ip x-forwarded-for IP address
  • rt Response Time
  • us USer
  • rf ReFerrer
• Right now, us for USer is only populated for Basic Auth; putting the Cloudflare user there would be great (doing that efficiently might involve transitioning to REMOTE_USER)

demodj/views.py:7

• [nitpick] Consider using a relative import (e.g. 'from .serializers import GroupSerializer, UserSerializer') for consistency within the package, unless the absolute import is intentional.

from demodj.serializers import GroupSerializer, UserSerializer

demodj/views.py:10

• Consider adding tests for this new endpoint to ensure its behavior under simulated delay conditions.
