func (eth *Ethereum) StateAtBlock(ctx context.Context, block *types.Block, reexec uint64, base *state.StateDB, readOnly bool, preferDisk bool) (statedb *state.StateDB, release tracers.StateReleaseFunc, err error)

StateAtBlock retrieves the state database associated with a certain block. If no state is locally available for the given block, a number of blocks are attempted to be reexecuted to generate the desired state. The optional base layer statedb can be provided which is regarded as the statedb of the parent block.

An additional release function will be returned if the requested state is available. Release is expected to be invoked when the returned state is no longer needed. Its purpose is to prevent resource leaking. Though it can be noop in some cases.

Parameters:

  • block: The block for which we want the state(state = block.Root)
  • reexec: The maximum number of blocks to reprocess trying to obtain the desired state
  • base: If the caller is tracing multiple blocks, the caller can provide the parent state continuously from the callsite.
  • readOnly: If true, then the live 'blockchain' state database is used. No mutation should be made from caller, e.g. perform Commit or other 'save-to-disk' changes. Otherwise, the trash generated by caller may be persisted permanently.
  • preferDisk: this arg can be used by the caller to signal that even though the 'base' is provided, it would be preferable to start from a fresh state, if we have it on disk.
