BigInv and ping/pong

[ISibboI]

Are the getbiginv and the ping and pong commands used? I have seen the sendbiginv method, but nothing to send a biginv request. And I have seen a sendpong method, but nothing to send a ping. Does a client have to implement these?

You're right, nothing sends a getbiginv request currently. It was added because I figured that it might some day be expensive to send a big inv message and thus it should be specifically asked for. But then I couldn't think of a reason not to ask so I didn't end up using it. It doesn't seem like implementing it should be necessary. Nothing sends pings currently but in the Bitcoin community there was talk of it being useful so I added it. It currently won't break anything if you don't implement pong replies to ping messages.

Ok, thanks.
