Why this should be merged
Coreth and Subnet-EVM require access to the current tx hash in the Warp precompile (for selecting the correct predicate results).
This can not be exposed as a wrapper through the
OverrideEVMResetArgsbecauseSetTxContextis called prior to resetting the EVM instance. Therefore, theSetTxContextfunction on any DB wrapper would never be called.How this works
Exposes the existing
txHashthrough aGetTxHash()function.How this was tested
Added a trivial unit test.
