Hi folks,

In case anyone else finds this useful, I wrote this:

https://git.zx2c4.com/git-daemon-dummy/about/

It's an epoll-based responder for git:// that simply returns an error telling users of a new URI. The purpose is to phase out git-daemon in favor of more secure TLS/HTTPS endpoints. With HTTPS certificates now being free, seems like this could be useful.

My personal motivation is that I'd like to just totally kill the git-daemon service, but somebody hard coded a URI of mine into a real printed textbook [1], so I don't want it to go stale suddenly. So, I need some way of informing users of the new URI.

Let me know what you think.

Jason

Neat.

Yeah, the existence of HTTPS (and the fact that the same URL can be both anonymous and authenticated) is nice. Unfortunately, git-over-https is not as efficient as the other protocols, because it's not asynchronously bi-directional. It would probably be relatively simple to make a "gits://" protocol, but I think it would be more interesting still if we could do git-over-websockets, to get the ubiquity benefits of HTTP.

I looked into it once, but was unable to find any reasonably sized explanation of how to implement either the server or client side of websockets. :)

Darn printed books. I thought the Ministry of Truth was supposed to take care of keeping our facts up to date.

Wikipedia explained handshake in four paragraphs. Then you only have to chew about ten pages of RFC6455, from page 27 to master data frames (and we probably just need binary frames for pkt-line, or fragmented when sending the pack). Come on, give us git+ws:// :D

PS. Too bad I couldn't find any minimal library that just deals with websocket data frame handling. I suppose curl can deal with handshake just fine.

That's interesting. I didn't realize that even the smart protocol was not as efficient as HTTP, but that makes sense. git+ws:// would indeed be quite nice!

Can't type today. *as efficient as git://
