any reason why this is still unimplemented?

Originally the answer to that question was because I overlooked it. Now the answer is because I don't know how. 😅 Looking at the old implementation hasn't helped so far.
I also overlooked StorageState.TrieState(), which I've implemented here.

I think you can use NewMerkleProof

@dimartiro thanks for pointing me towards NewMerkleProof(). There's just one issue; it expects a hashdb.HashDB and all i have is a ClientAdapterDB and a statemachine.Backend.

I think we should implement this in some point if we want to achieve a full read-only shim type. Do we have an issue for this one?

Is it part of #4807?

I think you can add more tests cases here since you added the api.StorageProvider implementation for Client
After #4792, StorageState methods that expected a state root hash now take a block hash. This updates all affected StorageState methods on ClientAdapter and simplifies their implementation.
Changes
This PR should cover all changes mentioned in the issue, except for changing
StorageState.Entries()to return astatemachine.PairsIter. As we discussed on Slack, this will be postponed since it is only used in RPC, which is currently not a priority.Regarding
LoadCode(); The implementation onClientAdapterexpects a block hash as the argument. The current implementation instate.InMemoryStorageStatecallsGetStorage(), which expects a state root hash. I'm pretty sure this is a long existing bug that hasn't been noticed becauseLoadCode()is called withnilon startup, which defaults to the best block.Tests
