Add a very basic many to many pubsub

[whyrusleeping]

This is experimental, but will very likely be merged into master.

For more information on the general protocol, take a look at: https://github.com/libp2p/pubsub-notes

and for the implementation being used here: https://github.com/whyrusleeping/go-floodsub

whoops, forgot the topic flag here

fix desc. Add a description, denoting experimental

[whyrusleeping]

@jbenet should we have the command set to be enabled by a config option? Or do you think that just stating in each commands helptext that its experimental is enough?

Hmmm. yeah i'd hide them unless either:

• a flag like ipfs daemon --experiment-pubsub or something, that flips a switch and everything is there.
• a config option like Experimental.PubSub = true

• a flag like ipfs daemon --experiment-pubsub or something, that flips a switch and everything is there.
• a config option like Experimental.PubSub = true

a flag would be better because a config option is hard to remove once it's there.

What about "subhub"?

[jbenet]

[jbenet]

it works 👍

[whyrusleeping]

Rebased on top of new libp2p changes that let us interop with js-ipfs. Also cleaned up a bunch of the code

[whyrusleeping]

Alright, merging this in. Its experimental, definitely subject to change, but man is it fun to play with.

@whyrusleeping Sweet! Are there any Go code examples using this functionality that I can check out?

[whyrusleeping]

Not yet! It's on my to-do list :)

Also some notes on performance. I just stumbled upon this (had no idea!), and am really interested. With that said, i've got no idea how well it scales, very broad performance characteristics, etc.

A high level paper would be very appreciated! Excellent work 💯 !

@whyrusleeping That is amazing, are you still planning to do any examples?
