Skip unactionable providers in check #70

2color · 2024-09-27T11:20:02Z

Problems

With feat: add ipni checks #66, we now get providers from the IPNI, however the Check backend only supports probing peers that support Bitswap, since both transport-graphsync-filecoinv1 and transport-ipfs-gateway-http are unsupported by both Boxo, Kubo and Rainbow.
The IPNI sometimes return duplicate providers (see screenhot)
Since we limit the number of providers we test to 10, we often end up in a situation where we get multiple unactionable providers from the IPNI and don't test any providers from the DHT (because it's usually slower to respond) and the loop exits once the max has reached, irrespective of the source of providers.

Example

Potential solutions

limit the number of providers from each source (DHT/IPNI) so that we always try to get providers from both
Skip providers that only transport-graphsync-filecoinv1 and [transport-ipfs-gateway-http]
Deduplicate providers from the IPNI so that we only test distinct PeerIDs once

Skip providers that only transport-graphsync-filecoinv1 and [transport-ipfs-gateway-http]

That this isn't happening is IIUC a bug, or at least inconsistent, behavior in boxo related to the ContentRouting interface wrapper for routing-v1 https://github.com/ipfs/boxo/blob/4af06fdc16292155a6ecb0dafa2a8c7d082a2b64/routing/http/contentrouter/contentrouter.go#L116.

It used to only support Bitswap, but now supports the PeerSchema. However, supporting the PeerSchema is likely not a good idea as most users cannot benefit from it and the PeerSchema should also be checked for Bitswap if the Protocols field is present.
- Note: this brings up an interesting case around what happens if proxying through delegated routing both provider records where the data transfer protocol is unknown and where it is known. Perhaps we should introduce a convention for a protocol called "unknown" so that if a user only wants peers that speak a given protocol (e.g. Bitswap) they can use either that protocol name or "unknown".

Deduplicate providers from the IPNI so that we only test distinct PeerIDs once

@gammazero I thought IPNI's (or at least cid.contact's) /routing/v1 endpoints were supposed to deduplicate identical responses instead of sending one-per-contextID as happens on the IPNI-specific endpoints (e.g. /cid) and that this used to happen. Am I mistaken?

Even if they're supposed to it might still make sense to handle deduplication in boxo to protect from buggy servers.

gammazero · 2024-09-27T14:59:32Z

@aschmahmann I thought that they were removing duplicates. Maybe it is not happening due to how streaming results are handled. Investigating.

It used to only support Bitswap, but now supports the PeerSchema. However, supporting the PeerSchema is likely not a good idea as most users cannot benefit from it and the PeerSchema should also be checked for Bitswap if the Protocols field is present.

I thought the point of PeerSchema is to allow for flexibility without requiring explicit code changes.

If we only allow PeerRecords with Protocols containing transport-bitswap here, this would cause someguy to only return bitswap providers, which would defeat the point of ipfs/specs#484.

Perhaps we should introduce a convention for a protocol called "unknown" so that if a user only wants peers that speak a given protocol (e.g. Bitswap) they can use either that protocol name or "unknown

We did exactly that in ipfs/specs#484, where we use unknown as a special "protocol name" to return provider peers from the DHT where bitswap is implied.

Just to confirm, in the results above, the CID bafybeicklkqcnlvtiscr2hzkubjwnwjinvskffn4xorqeduft3wq7vm5u4 returns results for a number of peers where the schema type is "peer". This is what IPNI now returns when the schema type is unknown.

gammazero · 2024-09-27T15:35:47Z

Deduplication should take place here: https://github.com/ipni/indexstar/blob/main/delegated_translator.go#L110-L137

However, if the advertised metadata is different for the different records but everything else is the same, then the records will still look like duplicates in ipfs-check because it is not showing that the metadata is different.

It is common for the same provider to store the same CID in multiple deals, and therefore with only different metadata. The metadata values may have the same protocols, but still be different.

@2color Does routerClient.FindProvidersAsync need a parameter to specify which schema types to include in results?

If we only allow PeerRecords with Protocols containing transport-bitswap here, this would cause someguy to only return bitswap providers, which would defeat the point of ipfs/specs#484.

Inside of boxo there are two different APIs used for content routing:

ContentRouting from go-libp2p https://github.com/libp2p/go-libp2p/blob/9038a72c4863778e6a26814aab201cee6d93d640/core/routing/routing.go#L26 (returns a peer.AddrInfo)
The delegated routing implementation that returns iterable record types iter.ResultIter[types.Record] https://github.com/ipfs/boxo/blob/4af06fdc16292155a6ecb0dafa2a8c7d082a2b64/routing/http/client/client.go#L183

In practice there is AFAIK no code that uses the ContentRouting interface and handles Bitswap + another protocol, so it seems fine to use that wrapper to handle just Bitswap / unknown rather than also shuffling say graphsync through it only for it to result in wasted connections for all real consumers.

So when we want to start checking other protocols besides bitswap we can use the libp2p content routing interface wrapper, since we'd want to surface the protocols anyway.

Note: The ContentRouting interface from go-libp2p will overtime likely be insufficient anyway since it doesn't convey protocol hints (even though those could get stashed in the peerstore), and doesn't handle non-libp2p data sources (e.g. if we support webseeds-like HTTP retrieval without requiring HTTP PeerID Auth)

However, if the advertised metadata is different for the different records but everything else is the same, then the records will still look like duplicates in ipfs-check because it is not showing that the metadata is different.

Updated: @gammazero it looks like you're right. The metadata is different for graphsync-filecoinv1 (IIRC it contains the piece CID info). This will go away once we filter out the graphsync data though.

Notice:

...M1zi is in the IPNI response 3 times
In the IPNI responses the protocol data is identical, but the filecoin graphsync metadata is not (iirc contains pieceCID info of the deal it's assocaited with)
It's also in the routing-v1 response 3 times
In routing-v1 response the protocol data is also identical

2color · 2024-09-30T11:24:26Z

Just to confirm, in the results above, the CID bafybeicklkqcnlvtiscr2hzkubjwnwjinvskffn4xorqeduft3wq7vm5u4 returns results for a number of peers where the schema type is peer. This is what IPNI now returns when the schema type is unknown.
See also: ipni/indexstar#147

That's useful to know. Does cid.contact return any other schemas from its delegated routing endpoint? Or only PeerSchema now

Deduplication should take place here: https://github.com/ipni/indexstar/blob/main/delegated_translator.go#L110-L137

However, if the advertised metadata is different for the different records but everything else is the same, then the records will still look like duplicates in ipfs-check because it is not showing that the metadata is different.

It is common for the same provider to store the same CID in multiple deals, and therefore with only different metadata. The metadata values may have the same protocols, but still be different.

So from the perspective of the IPNI, it sounds like you don't consider this a bug. Moreover, based on @aschmahmann's response:

This will go away once we filter out the graphsync data though.

IIUC @aschmahmann, your suggestion is to:

filter out graphsync providers in the delegated routing client
Forgo changing the contentrouter in boxo to accept filtering parameters.

What I'm still trying to understand from the discussion above is what the following looks like in practice:

So when we want to start checking other protocols besides bitswap we can use the libp2p content routing interface wrapper, since we'd want to surface the protocols anyway.

Currently, the wrapper implementation is built to satisfy the go-libp2p routing interface. Does this mean that as soon as we start supporting other protocols, i.e. gateway retrieval, in Boxo, we will need to evolve the wrapper in contentrouter anyways in a way that breaks compatibility with the go-libp2p routing interfaces?

Maybe, there's a few ways to make the changes but the end result is that we'll need an abstraction that allows passing more information from the content routing system into the data retrieval system. Maybe that looks like the interface we already have for delegated routing, maybe it looks like something else, we'll have to see how it goes as we start building

Update:

feat: add protocol and address filtering to delegated routing api boxo#678 implement client filtering to ensure we only check providers with bitswap
fix: limit providers from each source to half of max #71 ensures that we get results from both the IPNI and DHT
