Package vm implements the Matrix 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 Matrix yellow paper.

EVM is the Matrix 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 StateDBManager, chainConfig *params.ChainConfig, vmConfig Config, cointyp string) *EVM

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

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

func (*EVM) Create 

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

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) Interpreter 

func (evm *EVM) Interpreter() *Interpreter

Interpreter returns the EVM interpreter

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.

type GetHashFunc 

type GetHashFunc func(uint64) common.Hash

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

type Interpreter 

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

Interpreter is used to run Matrix based contracts and will utilise the passed environment to query external sources for state information. The Interpreter will run the byte code VM based on the passed configuration.

func NewInterpreter 

func NewInterpreter(evm *EVM, cfg Config) *Interpreter

NewInterpreter returns a new instance of the Interpreter.

func (*Interpreter) Run 

func (in *Interpreter) Run(contract *Contract, input []byte) (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 LogConfig 

type LogConfig struct {
	DisableMemory  bool // disable memory capture
	DisableStack   bool // disable stack capture
