SFTP API Explore

[turtle0x1]

LXD now has an API /1.0/instances/c1/sftp that upgrades to a "socket over PROTOCOL".

This upgrade changes the overhead requirements of the filesystem explorer drastically. We dont have to download items (potentially TB's in size) to work out if they are file or a directory.

So far it appears node (the language) isn't happy with this because it doesn't understand the upgrade to the protocol sftp but ssh2 does and all it does it has to give us the Net.Socket.

Okay so got the issue with a Net.Socket solved (LXD was missing a header).

ssh2 library, as predicted by others, was not happy with just being passed the underlying socket.

Which means we have to either;

• write a comptabilbe SFTP client in node (meh, maybe if I had a week off)
• use some forking model, which I dont like the sound of (the child process will need all the certs)
• rewrite the proxy in go (meh, might not be so bad)
