feat: access agent proofs method would fail to return some session proofs #1047

gobengo · 2023-10-31T00:15:14Z

Motivation:

fix w3cli bug I witnessed in my local setup Unauthorized: Claim {"can":"provider/add"} is not authorized when trying to register space - when juggling prod/staging W3UP_SERVICE_DID w3cli#113

Context

Why does this fix it?
- previously, it was possible for calls to Agent#registerSpace to fail due to invalid proofs, even if the underlying AgentData had the right proof. This was because registerSpace ends up calling invokeAndExecute(Provider.add), which calls invoke to build the invocation, which calls proofs to get the proofs for the invocation. And proofs could fail to include a sessionProof that was appropriate for the invocation audience of the invocation built by Agent#invoke. Now, Agent#proofs returns all the sessionProofs that might be relevant.

I don't really understand how this fixes the issue.

 * @returns {Record<string, Ucanto.Delegation>}
 */
-export function getSessionProofs(data) {
+export function getSessionProofs(data, issuer) {


Part of what was causing the bug is that this function ends up building a map of CIDs to proofs. The CID it uses is the nb.proof from a ucan/attest. The agent might actually have multiple ucan/attest ucans with the same nb.proof CID, but with different issuers. Previously only one of these delegations would end up in the returned map from this function, and the caller had no way of getting a session proof appropriate for the audience of their request.

I think this is fairly low level API so I suggest a breaking change that will change return type to

Record<Ucanto.DID, Record<string, ...Ucanto.Delegation>>

That way things will work correctly even if you do not pass the issuer. Furthermore I do have use case where I query proofs and I do not know the issuer of attestations so getting all the proofs would be desired there.

I did something like that here a9aedf6

One bit of cleanup, but I do think the proofs method signature needs some thought - happy to chat in higher bandwidth whenever's convenient for you!

I met with @Gozala about this and he agreed it makes sense. In the medium term we both don't love the Agent#proofs method API as is, and think maybe Agent#invoke should use something else to find the proofs for an invocation, but adding this option is a good stopgap to fix the bug in a backward-compatible way.

 export function getSessionProofs(data) {
-  /** @type {Record<string, Ucanto.Delegation>} */
+  /** @type {Record<string, [Ucanto.Delegation, ...Ucanto.Delegation[]]>} */


This is ok but I would prefer Record<Ucanto.DID, Record<string, ...Ucanto.Delegation>> per #1047 (comment) because it makes it a lot easier to pick the ones you care and throw away others as opposed to having to go and group them in another loop.

Not a big deal, but unless there is compelling reason to prefer this I would suggest reverse.

@Gozala roger. I will change to that.

I assume the keys of the inner record (typed as string) would be session proof issuer? and keys of outer record would be the attested to proof cid?

I was about to merge this, then did one last bit of testing in my local setup to make sure all this would still fix the situation for #113, but noticed that when I tried, I got a new 500 error from the backend. Two days ago I had tested and it worked. I think the regression happened because yesterday I took out the Agent#proofs option.sessionProofIssuer filter. This led to a simpler API, but at the cost of sometimes sending more sessionProofs than are needed in the invocation. I figured it would be harmless. But actually it was not harmless. Sending all those session proofs incl from unknown (to that service) issuers resulted in the upload-api lambda timing out for 10 seconds. I looked and was unable to find logs/sentry info that would hint at why, but my guess is that it was in the proof checking.

So I re-introduced options.sessionProofIssuer to Agent#proofs and re-added using it when Agent#invoke calls Agent#proofs to get proofs for the invocation. Once I made this change so ensure that Agent#invoke invocation doesn't include proof for sessions issued by issuers other than the invocation audience, then things work again.
I did that in this commit a1cee5e
