type EVM 

type EVM struct {
	// Context provides auxiliary blockchain related information
	Context
	// StateDB gives access to the underlying state
	StateDB StateDB
	// contains filtered or unexported fields
}

EVM is the Ethereum Virtual Machine base object and provides the necessary tools to run a contract on the given state with the provided context. It should be noted that any error generated through any of the calls should be considered a revert-state-and-consume-all-gas operation, no checks on specific errors should ever be performed. The interpreter makes sure that any errors generated are to be considered faulty code.

The EVM should never be reused and is not thread safe.

func NewEVM 

func NewEVM(ctx Context, statedb, privateState StateDB, chainConfig *params.ChainConfig, vmConfig Config) *EVM

NewEVM returns a new EVM. The returned EVM is not thread safe and should only ever be used *once*.

func (*EVM) CallCode 

func (evm *EVM) CallCode(caller ContractRef, addr common.Address, input []byte, gas uint64, value *big.Int) (ret []byte, leftOverGas uint64, err error)

CallCode executes the contract associated with the addr with the given input as parameters. It also handles any necessary value transfer required and takes the necessary steps to create accounts and reverses the state in case of an execution error or failed value transfer.

CallCode differs from Call in the sense that it executes the given address' code with the caller as context.

func (*EVM) CalledContracts 

func (evm *EVM) CalledContracts() []common.Address

Quorum

Returns addresses of contracts which are message-called

func (*EVM) Cancel

func (evm *EVM) Create2(caller ContractRef, code []byte, gas uint64, endowment *big.Int, salt *big.Int) (ret []byte, contractAddr common.Address, leftOverGas uint64, err error)

Create2 creates a new contract using code as deployment code.

The different between Create2 with Create is Create2 uses sha3(0xff ++ msg.sender ++ salt ++ sha3(init_code))[12:] instead of the usual sender-and-nonce-hash as the address where the contract is initialized at.

func (*EVM) CreatedContracts 

func (evm *EVM) CreatedContracts() []common.Address

Quorum

Returns addresses of contracts which are newly created

func (*EVM) DelegateCall 

func (evm *EVM) DelegateCall(caller ContractRef, addr common.Address, input []byte, gas uint64) (ret []byte, leftOverGas uint64, err error)

DelegateCall executes the contract associated with the addr with the given input as parameters. It reverses the state in case of an execution error.

DelegateCall differs from CallCode in the sense that it executes the given address' code with the caller as context and the caller is set to the caller of the caller.

func (*EVM) Depth

func (evm *EVM) Push(statedb StateDB)

func (*EVM) RevertToSnapshot 

func (evm *EVM) RevertToSnapshot(snapshot int)

We only need to revert the current state because when we call from private public state it's read only, there wouldn't be anything to reset. (A)->(B)->C->(B): A failure in (B) wouldn't need to reset C, as C was flagged read only.

func (*EVM) SetCurrentTX 

func (evm *EVM) SetCurrentTX(tx *types.Transaction)

func (*EVM) SetTxPrivacyMetadata 

func (evm *EVM) SetTxPrivacyMetadata(pm *types.PrivacyMetadata)

func (*EVM) StaticCall 

func (evm *EVM) StaticCall(caller ContractRef, addr common.Address, input []byte, gas uint64) (ret []byte, leftOverGas uint64, err error)

StaticCall executes the contract associated with the addr with the given input as parameters while disallowing any modifications to the state during the call. Opcodes that attempt to perform such modifications will result in exceptions instead of performing the modifications.

func (in *EVMInterpreter) Run(contract *Contract, input []byte, readOnly bool) (ret []byte, err error)

Run loops and evaluates the contract's code with the given input data and returns the return byte-slice and an error if one occurred.

It's important to note that any errors returned by the interpreter should be considered a revert-and-consume-all-gas operation except for errExecutionReverted which means revert-and-keep-gas-left.

type GetHashFunc 

type GetHashFunc func(uint64) common.Hash

GetHashFunc returns the n'th block hash in the blockchain and is used by the BLOCKHASH EVM op code.

type Interpreter 

type Interpreter interface {
	// Run loops and evaluates the contract's code with the given input data and returns
	// the return byte-slice and an error if one occurred.
	Run(contract *Contract, input []byte, static bool) ([]byte, error)
	// CanRun tells if the contract, passed as an argument, can be
	// run by the current interpreter. This is meant so that the
	// caller can do something like:
	//
	// “`golang
	// for _, interpreter := range interpreters {
	//   if interpreter.CanRun(contract.code) {
	//     interpreter.Run(contract.code, input)
	//   }
	// }
	// “`

func (*StructLog) OpName 

func (s *StructLog) OpName() string

OpName formats the operand name in a human-readable format.

func (*StructLog) UnmarshalJSON 

func (s *StructLog) UnmarshalJSON(input []byte) error

UnmarshalJSON unmarshals from JSON.

type StructLogger 

type StructLogger struct {
	// contains filtered or unexported fields
}

StructLogger is an EVM state logger and implements Tracer.

StructLogger can capture state based on the given Log configuration and also keeps a track record of modified storage which is used in reporting snapshots of the contract their storage.

func NewStructLogger 

func NewStructLogger(cfg *LogConfig) *StructLogger

NewStructLogger returns a new logger

func (*StructLogger) CaptureEnd 

func (l *StructLogger) CaptureEnd(output []byte, gasUsed uint64, t time.Duration, err error) error

CaptureEnd is called after the call finishes to finalize the tracing.

func (*StructLogger) CaptureFault 

func (l *StructLogger) CaptureFault(env *EVM, pc uint64, op OpCode, gas, cost uint64, memory *Memory, stack *Stack, contract *Contract, depth int, err error) error

CaptureFault implements the Tracer interface to trace an execution fault while running an opcode.

func (*StructLogger) CaptureStart 

func (l *StructLogger) CaptureStart(from common.Address, to common.Address, create bool, input []byte, gas uint64, value *big.Int) error

CaptureStart implements the Tracer interface to initialize the tracing operation.

func (*StructLogger) CaptureState 

func (l *StructLogger) CaptureState(env *EVM, pc uint64, op OpCode, gas, cost uint64, memory *Memory, stack *Stack, contract *Contract, depth int, err error) error

CaptureState logs a new structured log message and pushes it out to the environment

CaptureState also tracks SSTORE ops to track dirty values.

func (*StructLogger) Error 

func (l *StructLogger) Error() error

Error returns the VM error captured by the trace.

func (*StructLogger) Output 

func (l *StructLogger) Output() []byte

Output returns the VM return value captured by the trace.

func (*StructLogger) StructLogs 

func (l *StructLogger) StructLogs() []StructLog

StructLogs returns the captured log entries.

type Tracer 

type Tracer interface {
	CaptureStart(from common.Address, to common.Address, call bool, input []byte, gas uint64, value *big.Int) error
	CaptureState(env *EVM, pc uint64, op OpCode, gas, cost uint64, memory *Memory, stack *Stack, contract *Contract, depth int, err error) error
	CaptureFault(env *EVM, pc uint64, op OpCode, gas, cost uint64, memory *Memory, stack *Stack, contract *Contract, depth int, err error) error
	CaptureEnd(output []byte, gasUsed uint64, t time.Duration, err error) error
}

Tracer is used to collect execution traces from an EVM transaction execution. CaptureState is called for each step of the VM with the current VM state. Note that reference types are actual VM data structures; make copies if you need to retain them beyond the current call.

type TransferFunc 

type TransferFunc func(StateDB, common.Address, common.Address, *big.Int)

TransferFunc is the signature of a transfer function
