Forks table defines supported forks and their chain config.

Functions

func FromHex

func FromHex(s string) ([]byte, error)

FromHex returns the bytes represented by the hexadecimal string s. s may be prefixed with "0x". This is copy-pasted from bytes.go, which does not return the error

func MakePreState

func MakePreState(db ethdb.Database, accounts core.GenesisAlloc, snapshotter bool) *state.StateDB

Types

type BlockTest

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

A BlockTest checks handling of entire blocks.

func (*BlockTest) Run

func (t *BlockTest) Run(snapshotter bool) error

func (*BlockTest) UnmarshalJSON

func (t *BlockTest) UnmarshalJSON(in []byte) error

UnmarshalJSON implements json.Unmarshaler interface.

type DifficultyTest

type DifficultyTest struct {
	ParentTimestamp    uint64      `json:"parentTimestamp"`
	ParentDifficulty   *big.Int    `json:"parentDifficulty"`
	UncleHash          common.Hash `json:"parentUncles"`
	CurrentTimestamp   uint64      `json:"currentTimestamp"`
	CurrentBlockNumber uint64      `json:"currentBlockNumber"`
	CurrentDifficulty  *big.Int    `json:"currentDifficulty"`
}

func (DifficultyTest) MarshalJSON

func (d DifficultyTest) MarshalJSON() ([]byte, error)

MarshalJSON marshals as JSON.

func (*DifficultyTest) Run

func (test *DifficultyTest) Run(config *params.ChainConfig) error

func (*DifficultyTest) UnmarshalJSON

func (d *DifficultyTest) UnmarshalJSON(input []byte) error

UnmarshalJSON unmarshals from JSON.

type RLPTest

type RLPTest struct {
	// If the value of In is "INVALID" or "VALID", the test
	// checks whether Out can be decoded into a value of
	// type interface{}.
	//
	// For other JSON values, In is treated as a driver for
	// calls to rlp.Stream. The test also verifies that encoding
	// In produces the bytes in Out.
	In interface{}

	// Out is a hex-encoded RLP value.
	Out string
}

RLPTest is the JSON structure of a single RLP test.

func (*RLPTest) Run

func (t *RLPTest) Run() error

Run executes the test.

type StateSubtest

type StateSubtest struct {
	Fork  string
	Index int
}

StateSubtest selects a specific configuration of a General State Test.

type StateTest

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

StateTest checks transaction processing without block context. See https://github.com/ethereum/EIPs/issues/176 for the test format specification.

func (*StateTest) Run

func (t *StateTest) Run(subtest StateSubtest, vmconfig vm.Config, snapshotter bool) (*state.StateDB, error)

Run executes a specific subtest and verifies the post-state and logs

func (*StateTest) RunNoVerify

func (t *StateTest) RunNoVerify(subtest StateSubtest, vmconfig vm.Config, snapshotter bool) (*state.StateDB, common.Hash, error)

RunNoVerify runs a specific subtest and returns the statedb and post-state root

func (*StateTest) Subtests

func (t *StateTest) Subtests() []StateSubtest

Subtests returns all valid subtests of the test.

func (*StateTest) UnmarshalJSON

func (t *StateTest) UnmarshalJSON(in []byte) error

type TransactionTest

type TransactionTest struct {
	RLP            hexutil.Bytes `json:"rlp"`
	Byzantium      ttFork
	Constantinople ttFork
	Istanbul       ttFork
	EIP150         ttFork
	EIP158         ttFork
	Frontier       ttFork
	Homestead      ttFork
}

TransactionTest checks RLP decoding and sender derivation of transactions.

func (*TransactionTest) Run

func (tt *TransactionTest) Run(config *params.ChainConfig) error

type UnsupportedForkError

type UnsupportedForkError struct {
	Name string
}

UnsupportedForkError is returned when a test requests a fork that isn't implemented.

func (UnsupportedForkError) Error

func (e UnsupportedForkError) Error() string

type VMTest

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

VMTest checks EVM execution without block or transaction context. See https://github.com/ethereum/tests/wiki/VM-Tests for the test format specification.

func (*VMTest) Run

func (t *VMTest) Run(vmconfig vm.Config, snapshotter bool) error

func (*VMTest) UnmarshalJSON

func (t *VMTest) UnmarshalJSON(data []byte) error
