Resolving links in sharded directories does not seem to work

[victorb]

Version information:

Gateways running commit 1dede1b

Type:

Bug

Description:

I've tried three projects that are using sharded directories and one without. The one without resolves links correctly but none of the projects using sharded directories works for resolving links. However, it does work when using 0.4.15

• https://localhost:7002/ipns/arch.victor.earth/community works correctly (using version 0.4.15)
• https://ipfs.io/ipns/arch.victor.earth/community gets error message ipfs resolve -r /ipns/arch.victor.earth/community: no link by that name

Likely introduced in #4672 which switched from using path.pesolver.ResolvePath to path.pesolver.ResolveToLastNode which doesn't appear to respect Resolver.ResolveOnce. As the gateway uses coreapi it got affected by this

@magik6k something is still weird here...

https://ipfs.io/ipfs/QmXeh5S5Dk528ueFX3iFRB5TuKUNrWM9dEiLfC4crVwuHD is a sharded directory.

https://ipfs.io/ipfs/QmXeh5S5Dk528ueFX3iFRB5TuKUNrWM9dEiLfC4crVwuHD/PAL_Express.html gives me no link by that name

If I look on the IPLD explorer and take that path: https://explore.ipld.io/#/explore/QmXeh5S5Dk528ueFX3iFRB5TuKUNrWM9dEiLfC4crVwuHD it would be 27PAL_Express.html

https://ipfs.io/ipfs/QmXeh5S5Dk528ueFX3iFRB5TuKUNrWM9dEiLfC4crVwuHD/27PAL_Express.html gives me inconsistent ResolveOnce / nd.Resolve

Also:

$ ipfs resolve /ipfs/QmXeh5S5Dk528ueFX3iFRB5TuKUNrWM9dEiLfC4crVwuHD/PAL_Express.html
Error: no link named "PAL_Express.html" under QmXeh5S5Dk528ueFX3iFRB5TuKUNrWM9dEiLfC4crVwuHD
