Handling log file rotation

[BoyanH]

I am using the logconfig_dict configuration key to log to a file vialogging.FileHandler. Then I'm using logrotate to rotate the log files daily, something similar to:

/var/log/my-app.log {
 daily
 rotate 30
 compress
 dateext
 dateformat .%Y-%m-%d
 notifempty
 sharedscripts
 postrotate
     kill -USR1 $(cat /path-to/my-app.pid)
 endscript
}

Coming from a Flask+Gunicorn setup, I am using kill -USR1 $(cat /path-to/my-app.pid) to signal that the log files have changed and need to be reopened. The /path-to/my-app.pid is configured via pid_path.

Hypercorn isn't handling the signal the way Gunicorn does (or not at all) and the server is simply shut down. How should I go about implementing a similar logic in Hypercorn?
