c3queue is a small Python web app, generating the page at
https://c3queue.de. It displays the (historical and current) waiting time at
the ticket queue at Chaos Communication Congress.
c3queue integrates with postix. If you want to use it with your postix
installation, you'll have to empty the c3queue.csv file, and choose a
secret passphrase. Enter the passphrase in your postix configuration, and also
set it as environment variable C3QUEUE_SECRET when starting the c3queue server.
Other than that, install the requirements and run the server using just (you'll need Python 3.9+):
just install --extra prod # Install dependencies just run # Run development server at :8001 just server # Run production server with gunicorn
Or run manually with any of the methods in the aiohttp docs, for example with gunicorn:
uv run gunicorn --bind unix:/run/gunicorn/c3queue --worker-class aiohttp.GunicornWebWorker src.c3queue:main
c3queue expects to receive POST requests on the /pong endpoint in the
format:
HTTP POST /pong Authorization: thesecrettoken ping=2018-12-26+16%3A30%3A25&pong=2018-12-26+16%3A33%3A02
The timestamp format is only loosely defined. Everything that the dateutil
library can parse by default will be understood.
