Constants

const DisallowEOF = true

DisallowEOF makes it so that any statetest that are created never contain 0xEF-prefixed code. See https://github.com/holiman/goevmlab/issues/127

Types

type GeneralStateTest

type GeneralStateTest map[string]*stJSON

func FromGeneralStateTest

func FromGeneralStateTest(name string) (*GeneralStateTest, error)

type GenesisAccount

type GenesisAccount struct {
	Code []byte `json:"code"`
	// N.B: parity demands storage even if it's empty
	Storage    map[common.Hash]common.Hash `json:"storage"`
	Balance    *big.Int                    `json:"balance" gencodec:"required"`
	Nonce      uint64                      `json:"nonce"`
	PrivateKey []byte                      `json:"secretKey,omitempty"` // for tests
}

GenesisAccount is an account in the state of the genesis block. Copied from go-ethereum, with the mod of making Storage mandatory

func (GenesisAccount) MarshalJSON

func (g GenesisAccount) MarshalJSON() ([]byte, error)

MarshalJSON marshals as JSON.

func (*GenesisAccount) UnmarshalJSON

func (g *GenesisAccount) UnmarshalJSON(input []byte) error

UnmarshalJSON unmarshals from JSON.

type GenesisAlloc

type GenesisAlloc map[common.Address]GenesisAccount

GenesisAlloc specifies the initial state that is part of the genesis block.

func (*GenesisAlloc) UnmarshalJSON

func (ga *GenesisAlloc) UnmarshalJSON(data []byte) error

type GstMaker

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

GstMaker is a construct to generate General State Tests

func (*GstMaker) EnableFork

func (g *GstMaker) EnableFork(fork string)

func (*GstMaker) Fill

func (g *GstMaker) Fill(traceOutput io.Writer) error

FillTest uses go-ethereum internally to determine the state root and logs, and optionally outputs the trace to the given writer (if non-nil)

func (*GstMaker) GetDestination

func (g *GstMaker) GetDestination() common.Address

GetDestination returns the to- address from the tx

func (*GstMaker) SetCode

func (g *GstMaker) SetCode(address common.Address, code []byte)

SetCode sets the code at the given address (creating the account if it did not previously exist)

func (*GstMaker) SetPre
