What is the rationale for using
How is it possible to do that in general case? Wouldn't you have a TOCTOU problem? |

This PR is building upon paritytech/substrate#12707 and is related to paritytech/polkadot-sdk#793
The problem
All runtime calls first check the runtime version before issuing the actual runtime api call. If a call is made for a block which is pruned (e.g. because a better fork was finalized), the runtime api version can't be checked and
NotSupportederror is returned. This is misleading because the problem is different. The call IS supported but it can't be executed at a pruned block.How this is solved
This PR adds explicit logging for
UnknownBlockruntime errors so that it is clear why the runtime call is failing. FurthermoreUnknownBlockvariant is added toRuntimeApiErrorenum innode/subsystem-types/src/errors.rs. This allows any subsystem to handle such errors in its own way.What this PR doesn't do
The PR doesn't fix the root cause (prevent executing logic on pruned blocks).
