Overview

Package vm implements the Ethereum Virtual Machine.

The vm package implements one EVM, a byte code VM. The BC (Byte Code) VM loops over a set of bytes and executes them according to the set of rules defined in the Ethereum yellow paper.

Package vm is a generated GoMock package.

Types

type AccountExtraDataStateGetter 

type AccountExtraDataStateGetter interface {
	// Return nil for public contract
	GetPrivacyMetadata(addr common.Address) (*state.PrivacyMetadata, error)
	GetManagedParties(addr common.Address) ([]string, error)
}

type AccountExtraDataStateSetter 

type AccountExtraDataStateSetter interface {
	SetPrivacyMetadata(addr common.Address, pm *state.PrivacyMetadata)
	SetManagedParties(addr common.Address, managedParties []string)
}

type AccountRef 

type AccountRef common.Address

AccountRef implements ContractRef.

Account references are used during EVM initialisation and it's primary use is to fetch addresses. Removing this object proves difficult because of the cached jump destinations which are fetched from the parent contract (i.e. the caller), which is a ContractRef.

func (AccountRef) Address 

func (ar AccountRef) Address() common.Address

Address casts AccountRef to a Address

type AffectedReason 

type AffectedReason byte

AffectedReason defines a type of operation that was applied to a contract. 

const (
	Creation AffectedReason = iota
	MessageCall
)

type BlockContext 

type BlockContext struct {
	// CanTransfer returns whether the account contains
	// sufficient ether to transfer the value
	CanTransfer CanTransferFunc
	// Transfer transfers ether from one account to the other
	Transfer TransferFunc
	// GetHash returns the hash corresponding to n
	GetHash GetHashFunc

	// Block information
	Coinbase    common.Address // Provides information for COINBASE
	GasLimit    uint64         // Provides information for GASLIMIT
	BlockNumber *big.Int       // Provides information for NUMBER
	Time        *big.Int       // Provides information for TIME

}

BlockContext provides the EVM with auxiliary information. Once provided it shouldn't be modified.

type CallContext 

type CallContext interface {
	// Call another contract
	Call(env *EVM, me ContractRef, addr common.Address, data []byte, gas, value *big.Int) ([]byte, error)
	// Take another's contract code and execute within our own context
	CallCode(env *EVM, me ContractRef, addr common.Address, data []byte, gas, value *big.Int) ([]byte, error)
	// Same as CallCode except sender and value is propagated from parent to child scope
	DelegateCall(env *EVM, me ContractRef, addr common.Address, data []byte, gas *big.Int) ([]byte, error)
	// Create a new contract
	Create(env *EVM, me ContractRef, data []byte, gas, value *big.Int) ([]byte, common.Address, error)
}

CallContext provides a basic interface for the EVM calling conventions. The EVM depends on this context being implemented for doing subcalls and initialising new EVM contracts.

type CanTransferFunc 

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

CanTransferFunc is the signature of a transfer guard function

type Config 

type Config struct {

	JumpTable [256]*operation // EVM instruction table, automatically populated if unset

	EWASMInterpreter string // External EWASM interpreter options
	EVMInterpreter   string // External EVM interpreter options

	ExtraEips []int // Additional EIPS that are to be enabled

	ApplyOnPartyOverride *types.PrivateStateIdentifier
}

Config are the configuration options for the Interpreter

type Contract 

type Contract struct {
	// CallerAddress is the result of the caller which initialised this
	// contract. However when the "call method" is delegated this value
	// needs to be initialised to that of the caller's caller.
	CallerAddress common.Address

	Code     []byte
	CodeHash common.Hash
	CodeAddr *common.Address

}

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(blockCtx BlockContext, txCtx TxContext, statedb, privateState StateDB, chainConfig *params.ChainConfig, vmConfig Config) *EVM

ActivePrecompiles returns the addresses of the precompiles enabled with the current configuration

func (*EVM) AffectedContracts 

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

Quorum

AffectedContracts returns all affected contracts that are the results of MessageCall transaction

func (*EVM) CalculateMerkleRoot 

func (evm *EVM) CalculateMerkleRoot() (common.Hash, error)

Return MerkleRoot of all affected contracts (due to both creation and message call)

func (*EVM) Call 

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

Call 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.

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) Cancel 

func (evm *EVM) Cancel()

Cancel cancels any running EVM operation. This may be called concurrently and it's safe to be called multiple times.

func (*EVM) Cancelled

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.

func (evm *EVM) Push(statedb StateDB)

func (*EVM) Reset 

func (evm *EVM) Reset(txCtx TxContext, statedb StateDB)

Reset resets the EVM with a new transaction context.Reset This is not threadsafe and should only be done very cautiously.

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.

	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)
	//   }
	// }
	// “`
