This is done with the intention to add new {Get,Subscribe}ActorEvents in a
future release (i.e. soon!) with both decoded values (dag-json represented)
and simplified (no flags or codec). But because this comes with some
trade-offs wrt fidelity of information (e.g. likely needing to drop events with
badly encoded values, and not retaining original codec), we need to also have
a Raw form of these APIs for consumers that want to take on the burden of
consuming them as they are.
Fixes: #10814
This PR updates the following RPC methods according to EIP-1898
specs.
The following RPC methods are affected:
- eth_getBalance
- eth_getStorageAt
- eth_getTransactionCount
- eth_getCode
- eth_call
Note that eth_getBlockByNumber was not included in this list in
the spec although it seems it should be affected also?
Currently these methods all accept a blkParam string which can be
one of "latest", "earliest", "pending", or a block number (decimal
or hex). The spec enables caller to additionally specify a json
hash which can include the following fields:
- blockNumber EthUint64: A block number (decimal or hex) which is
similar to the original use of the blkParam string
- blockHash EthHash: The block hash
- requireCanonical bool) If true we should make sure the block is
in the canonical chain
Since the blkParam needs to support both being a number/string and
a json hash then this to properly work we need to introduce a new
struct with pointer fields to check if they exist. This is done
in the EthBlockParamByNumberOrHash struct which first tries to
unmarshal as a json hash (according to eip-1898) and then fallback
to unmarshal as string/number.
This is identical to ChainGetTipSetByHeight, but returns the tipset
following any null tipsets. This is what the user usually wants anyways.
(and I need it for another PR)
