If I write a web server using asyncio (and the aiohttp package), I can spin up the server with:
await loop.create_server(app.make_handler(), "0.0.0.0", 8080) This works fine for a high port, but if I want to bind to port 80, I need to either start as root and then drop privileges, or get given the socket by someone else. With systemd, the latter is an option; you configure a service unit and a socket unit, and when the service gets started, it's given a bound listening socket as FD 3. Most of the work is pretty straight-forward, but I ran into one problem. The event loop's create_server() method calls a private _start_serving method, which means I can't (or rather, I shouldn't) just replicate create_server. This works, but it's naughty: sock = socket.socket(fileno=3) sock.setblocking(False) loop._start_serving(app.make_handler(), sock) What's the official way to say to asyncio "here's a listening socket, start managing it for me"?
