Socket handler setup

[Roberthh]

I see this line e.g. in webrepl:

Code: Select all

setsockopt(socket.SOL_SOCKET, 20, handler) 

I can guess the purpose, but is that somewhere documented? And were is it implemented?

This commit is pretty relevant and should show how it works: https://github.com/micropython/micropyt ... abe0ea66e3

I wasn't able to find any documentation on it when I looked it up and I would be curious why the literal value 20 was used.

Thanks. I'm trying to set up the background ftp server. For single command it works, but for two stage commands it looks like the seconds connection disappears between commands. I have to dig further.
Update: Some progress, although with a hammer. ls command works.
