I was looking through the list, and mostly realise I still wouldn't really know where to put a new debug message. At the same time I realised that this is a solved problem. So I am wondering, shouldn't we just use default logging facility stuff, so basically: fatal / error / warning / info / debug.

• Fatal: an error we cannot recover from. You can expect degraded performance because of it.
• Error: an error we recovered from, for example by showing a (clear) error to the user.
• Warning: things that are not right, but also not wrong.
• Info: things worth mentioning to the user if he is interested.
• Debug: not useful for anyone except when debugging a problem.

When I map that to the DEBUG entries we have, you get something like:

0 - Fatal - cannot bind, cannot create socket, cannot redirect DEBUG, cannot open file, setting non-blocking fails, illegal packet received
1 - Error - disconnect from server, connection lost, broadcast failed
2 - Warning - "loading game failed, so a new game will be started", wrong password, invalid chat action, not supported (admin stuff)
3 - Info - client connected, starting network, shutdown network
4 - ??
5 - Debug 1 - DNS resolvement, connection attempts, server responses
6 - Debug 2 - Details DNS resolvement, HTTP connect, redirect, download status
7 - Trace - Received frame / sent frame

And we change the Dedicated server to be on net=4 (instead of net=6)

Here are all the current net logs in the game, which helped me to get a bit of feeling for it:
