Functions ¶
func RegisterLookup ¶
func RegisterLookup(wildcard bool, lookup lookupFunc)
RegisterLookup registers a method as a lookup for tracers, meaning that users can invoke a named tracer through that lookup. If 'wildcard' is true, then the lookup will be placed last. This is typically meant for interpreted engines (js) which can evaluate dynamic user-supplied code.
Types ¶
type API ¶
type API struct {
// contains filtered or unexported fields
}
API is the collection of tracing APIs exposed over the private debugging endpoint.
func (*API) GetBlockTraceByNumberOrHash ¶
func (api *API) GetBlockTraceByNumberOrHash(ctx context.Context, blockNrOrHash rpc.BlockNumberOrHash, config *TraceConfig) (trace *types.BlockTrace, err error)
GetBlockTraceByNumberOrHash replays the block and returns the structured BlockTrace by hash or number.
func (*API) IntermediateRoots ¶
func (api *API) IntermediateRoots(ctx context.Context, hash common.Hash, config *TraceConfig) ([]common.Hash, error)
IntermediateRoots executes a block (bad- or canon- or side-), and returns a list of intermediate roots: the stateroot after each transaction.
func (*API) StandardTraceBadBlockToFile ¶
func (api *API) StandardTraceBadBlockToFile(ctx context.Context, hash common.Hash, config *StdTraceConfig) ([]string, error)
StandardTraceBadBlockToFile dumps the structured logs created during the execution of EVM against a block pulled from the pool of bad ones to the local file system and returns a list of files to the caller.
func (*API) StandardTraceBlockToFile ¶
func (api *API) StandardTraceBlockToFile(ctx context.Context, hash common.Hash, config *StdTraceConfig) ([]string, error)
StandardTraceBlockToFile dumps the structured logs created during the execution of EVM to the local file system and returns a list of files to the caller.
func (*API) TraceBadBlock ¶
func (api *API) TraceBadBlock(ctx context.Context, hash common.Hash, config *TraceConfig) ([]*txTraceResult, error)
TraceBadBlock returns the structured logs created during the execution of EVM against a block pulled from the pool of bad ones and returns them as a JSON object.
func (*API) TraceBlock ¶
func (api *API) TraceBlock(ctx context.Context, blob []byte, config *TraceConfig) ([]*txTraceResult, error)
TraceBlock returns the structured logs created during the execution of EVM and returns them as a JSON object.
func (*API) TraceBlockByHash ¶
func (api *API) TraceBlockByHash(ctx context.Context, hash common.Hash, config *TraceConfig) ([]*txTraceResult, error)
TraceBlockByHash returns the structured logs created during the execution of EVM and returns them as a JSON object.
func (*API) TraceBlockByNumber ¶
func (api *API) TraceBlockByNumber(ctx context.Context, number rpc.BlockNumber, config *TraceConfig) ([]*txTraceResult, error)
TraceBlockByNumber returns the structured logs created during the execution of EVM and returns them as a JSON object.
func (*API) TraceBlockFromFile ¶
func (api *API) TraceBlockFromFile(ctx context.Context, file string, config *TraceConfig) ([]*txTraceResult, error)
TraceBlockFromFile returns the structured logs created during the execution of EVM and returns them as a JSON object.
func (*API) TraceCall ¶
func (api *API) TraceCall(ctx context.Context, args ethapi.TransactionArgs, blockNrOrHash rpc.BlockNumberOrHash, config *TraceCallConfig) (interface{}, error)
TraceCall lets you trace a given eth_call. It collects the structured logs created during the execution of EVM if the given transaction was added on top of the provided block and returns them as a JSON object. You can provide -2 as a block number to trace on top of the pending block.
func (*API) TraceChain ¶
func (api *API) TraceChain(ctx context.Context, start, end rpc.BlockNumber, config *TraceConfig) (*rpc.Subscription, error)
TraceChain returns the structured logs created during the execution of EVM between two blocks (excluding start) and returns them as a JSON object.
func (*API) TraceTransaction ¶
func (api *API) TraceTransaction(ctx context.Context, hash common.Hash, config *TraceConfig) (interface{}, error)
TraceTransaction returns the structured logs created during the execution of EVM and returns them as a JSON object.
type Backend ¶
type Backend interface { HeaderByHash(ctx context.Context, hash common.Hash) (*types.Header, error) HeaderByNumber(ctx context.Context, number rpc.BlockNumber) (*types.Header, error) BlockByHash(ctx context.Context, hash common.Hash) (*types.Block, error) BlockByNumber(ctx context.Context, number rpc.BlockNumber) (*types.Block, error) GetTransaction(ctx context.Context, txHash common.Hash) (*types.Transaction, common.Hash, uint64, uint64, error) RPCGasCap() uint64 ChainConfig() *params.ChainConfig CacheConfig() *core.CacheConfig Engine() consensus.Engine ChainDb() ethdb.Database // StateAtBlock returns the state corresponding to the stateroot of the block. // N.B: For executing transactions on block N, the required stateRoot is block N-1, // so this method should be called with the parent. StateAtBlock(ctx context.Context, block *types.Block, reexec uint64, base *state.StateDB, checkLive, preferDisk bool) (*state.StateDB, error) StateAtTransaction(ctx context.Context, block *types.Block, txIndex int, reexec uint64) (core.Message, vm.BlockContext, *state.StateDB, error) }
Backend interface provides the common API services (that are provided by both full and light clients) with access to necessary functions.
type Context ¶
type Context struct { BlockHash common.Hash // Hash of the block the tx is contained within (zero if dangling tx or call) TxIndex int // Index of the transaction within a block (zero if dangling tx or call) TxHash common.Hash // Hash of the transaction being traced (zero if dangling call) }
Context contains some contextual infos for a transaction execution that is not available from within the EVM object.
type StdTraceConfig ¶
StdTraceConfig holds extra parameters to standard-json trace functions.
type TraceBlock ¶
type TraceBlock interface {
GetBlockTraceByNumberOrHash(ctx context.Context, blockNrOrHash rpc.BlockNumberOrHash, config *TraceConfig) (trace *types.BlockTrace, err error)
}
type TraceCallConfig ¶
type TraceCallConfig struct { *vm.LogConfig Tracer *string Timeout *string Reexec *uint64 StateOverrides *ethapi.StateOverride }
TraceCallConfig is the config for traceCall API. It holds one more field to override the state for tracing.
type TraceConfig ¶
TraceConfig holds extra parameters to trace functions.
