Functions

func ComputeTxEnv

func ComputeTxEnv(ctx context.Context, engine consensus.EngineReader, block *types.Block, cfg *chain.Config, headerReader services.HeaderReader, dbtx kv.Tx, txIndex int, historyV3 bool) (core.Message, evmtypes.BlockContext, evmtypes.TxContext, *state.IntraBlockState, state.StateReader, error)

ComputeTxEnv returns the execution environment of a certain transaction.

func DoCall

func DoCall(
	ctx context.Context,
	engine consensus.EngineReader,
	args ethapi2.CallArgs,
	tx kv.Tx,
	blockNrOrHash rpc.BlockNumberOrHash,
	header *types.Header,
	overrides *ethapi2.StateOverrides,
	gasCap uint64,
	chainConfig *chain.Config,
	stateReader state.StateReader,
	headerReader services.HeaderReader,
	callTimeout time.Duration,
) (*core.ExecutionResult, error)

func MakeHeaderGetter

func MakeHeaderGetter(requireCanonical bool, tx kv.Tx, headerReader services.HeaderReader) func(uint64) libcommon.Hash

func NewEVMBlockContext

func NewEVMBlockContext(engine consensus.EngineReader, header *types.Header, requireCanonical bool, tx kv.Tx, headerReader services.HeaderReader) evmtypes.BlockContext

func TraceTx

func TraceTx(
	ctx context.Context,
	message core.Message,
	blockCtx evmtypes.BlockContext,
	txCtx evmtypes.TxContext,
	ibs evmtypes.IntraBlockState,
	config *tracers.TraceConfig,
	chainConfig *chain.Config,
	stream *jsoniter.Stream,
	callTimeout time.Duration,
) error

TraceTx configures a new tracer according to the provided configuration, and executes the given message in the provided environment. The return value will be tracer dependent.

Types

type BlockGetter

	// GetBlockByHash retrieves a block from the database by hash, caching it if found.
	GetBlockByHash(hash libcommon.Hash) (*types.Block, error)
	// GetBlock retrieves a block from the database by hash and number,
	// caching it if found.
	GetBlock(hash libcommon.Hash, number uint64) *types.Block
}
