Just to note, we should only ever see a zero value for a node that is not "Removed" if we are at a block height prior to EIP-158 activation (which is when zeroed value pruning begun). Does this make sense, and align with what we are seeing?

I think we need the analogous check in the account retrieval methods above (RetrieveAccountByAddressAndBlockNumber and RetrieveAccountByAddressAndBlockHash) and the other storage retrieval method below (RetrieveStorageAtByAddressAndStorageKeyAndBlockNumber).

We're running a local/private chain for which the value in genesis is "eip158Block": 0,, so this isn't consistent with what we expect?

Where is RetrieveAccountByAddressAndBlockNumber function called? I couldn't find it. And how to test account deleting?

It makes sense but doesn't align with current behavior. Isn't this misalignment was introduced here in this PR https://github.com/vulcanize/go-ethereum/pull/58 ?

I think we want to fix the function even if it isn't currently called. We could test account deleting similar to how we do it here: https://github.com/vulcanize/go-ethereum/blob/v1.10.7-statediff/statediff/builder_test.go#L1318

If that is the cause of the misalignment then all we need to do is check that the node isn't a "Removed" type when we query for the latest value at a given path/key, which I think we are already doing?

@arijitAD is taking over here, to echo what I told him in slack:

First thing to do is verify that we are excluding "Removed" type nodes when we perform those queries.

If we arent doing that then we are actually just seeing null values where they are supposed to be, and need to add a check to filter those out

But I think we are already filtering out "Removed" nodes in those queries, and if we are already doing that then there is some deeper reason as to why we are seeing null values for nodes that are not of the "Removed" type

Another possible lead is how we (and geth) are distinguishing (or not) between true nulls and legitimate zero values

Review

On the other side of this coin, if 0 values are not showing up when they are supposed to it is likely because the query being made against the database does not properly consider the "Removed" node type entries as indicating a 0 value and instead the query finds the last entry where the node is not "Removed" and returns that latest non-zero value (which is the behavior we want in some cases, but not here).

Please see https://github.com/vulcanize/ipld-eth-server/issues/95#issuecomment-918202095 there is a much simpler fix now that we have leaf_key for "Removed" nodes
