Summary

This PR adds ability to expose Kubo's routing system as /routing/v1 on the gateway port.
This feature is disabled by default, requires opt-in via config (Gateway.ExposeRoutingAPI=true).

Closes #9875. Uses boxo/routing/http/server to implement the Routing v1 HTTP server in Kubo.

@lidel I had completely missed the part of your comment on renaming get-ipns and put-ipns in the router configuration to find-ipns and provide-ipns. I do think we should solve this.

Get and Put for IPNS are historically related to it adhering to the routing API which uses routing.ValueStore, which uses Get/Put names in the code. At the same time, peer and providers have been called find and provide in other parts of the code. Therefore, that could be more consistent with remaining code, but not with the other methods of the routing v1.

I’m up to either:

  1. Change Kubo to find-ipns and provide-ipns; or
  2. Change Boxo to keep GetIPNS and PutIPNS - more consistent with Libp2p stack naming.

What do you think?

@hacdias I'm leaning towards (2): keeping get-ipns and put-ipns in Kubo config and renaming to GetIPNS and PutIPNS here because

(Apologies for flip-flopping this so many times, not familiar with naming conventions here as much as I would like to, but (2) seems to make most sense given the information we have now)

@lidel agreed. Done both in Boxo and here. I think #9877 (comment) is the only missing thing to decide on to be able to merge Boxo and then this one.

ℹ️ we do this for WebUI URL, would not hurt here – makes it easy for user to eyeball if it is enabled, and copy URL for testing.

Thank you for including end-to-end in test/cli/delegated_routing_v1_http_proxy_test.go 👍

Since this is opt-in via Gateway.ExposeRoutingAPI, I think its good enough for giving it a try in Kubo 0.23
