Variables ¶
var EnableGasTracing = os.Getenv("VENUS_VM_ENABLE_GAS_TRACING_VERY_SLOW") == "1"
EnableGasTracing, if true, outputs gas tracing in execution traces.
Functions ¶
func ComputeGasOverestimationBurn ¶
ComputeGasOverestimationBurn computes amount of gas to be refunded and amount of gas to be burned Result is (refund, burn)
Types ¶
type GasCharge ¶
type GasCharge struct {
Name string
Extra interface{}
ComputeGas int64
StorageGas int64
VirtualCompute int64
VirtualStorage int64
}
GasCharge amount of gas consumed at one time
func (GasCharge) WithVirtual ¶
type GasOutputs ¶
type GasOutputs struct {
BaseFeeBurn abi.TokenAmount
OverEstimationBurn abi.TokenAmount
MinerPenalty abi.TokenAmount
MinerTip abi.TokenAmount
Refund abi.TokenAmount
GasRefund int64
GasBurned int64
}
GasOutputs detail of gas after message executed
func ComputeGasOutputs ¶
func ComputeGasOutputs(gasUsed, gasLimit int64, baseFee, feeCap, gasPremium abi.TokenAmount, chargeNetworkFee bool) GasOutputs
ComputeGasOutputs compute gas outputs base on message gas parameters and gasUsed after executed
func ZeroGasOutputs ¶
func ZeroGasOutputs() GasOutputs
ZeroGasOutputs returns a logically zeroed GasOutputs.
type GasTracker ¶
type GasTracker struct {
GasAvailable int64
GasUsed int64
ExecutionTrace types.ExecutionTrace
NumActorsCreated uint64 //nolint
AllowInternal bool //nolint
CallerValidated bool //nolint
LastGasChargeTime time.Time //nolint
LastGasCharge *types.GasTrace
}
GasTracker maintains the stateView of gas usage throughout the execution of a message.
func NewGasTracker ¶
func NewGasTracker(limit int64) *GasTracker
NewGasTracker initializes a new empty gas tracker
func (*GasTracker) Charge ¶
func (t *GasTracker) Charge(gas GasCharge, msg string, args ...interface{})
Charge will add the gas charge To the current Method gas context.
WARNING: this Method will panic if there is no sufficient gas left.
func (*GasTracker) TryCharge ¶
func (t *GasTracker) TryCharge(gasCharge GasCharge) bool
TryCharge charges `amount` or `RemainingGas()“, whichever is smaller.
Returns `True` if the there was enough gas To pay for `amount`.
type Pricelist ¶
type Pricelist interface {
// OnChainMessage returns the gas used for storing a message of a given size in the chain.
OnChainMessage(msgSize int) GasCharge
// OnChainReturnValue returns the gas used for storing the response of a message in the chain.
OnChainReturnValue(dataSize int) GasCharge
// OnMethodInvocation returns the gas used when invoking a method.
OnMethodInvocation(value abi.TokenAmount, methodNum abi.MethodNum) GasCharge
// OnIpldGet returns the gas used for storing an object
OnIpldGet() GasCharge
// OnIpldPut returns the gas used for storing an object
OnIpldPut(dataSize int) GasCharge
// OnCreateActor returns the gas used for creating an actor
OnCreateActor() GasCharge
// OnDeleteActor returns the gas used for deleting an actor
OnDeleteActor() GasCharge
OnVerifySignature(sigType crypto.SigType, planTextSize int) (GasCharge, error)
OnHashing(dataSize int) GasCharge
OnComputeUnsealedSectorCid(proofType abi.RegisteredSealProof, pieces []abi.PieceInfo) GasCharge
OnVerifySeal(info proof7.SealVerifyInfo) GasCharge
OnVerifyAggregateSeals(aggregate proof7.AggregateSealVerifyProofAndInfos) GasCharge
OnVerifyReplicaUpdate(update proof7.ReplicaUpdateInfo) GasCharge
OnVerifyPost(info proof7.WindowPoStVerifyInfo) GasCharge
OnVerifyConsensusFault() GasCharge
}
Pricelist provides prices for operations in the VM.
Note: this interface should be APPEND ONLY since last chain checkpoint
type PricesSchedule ¶
type PricesSchedule struct {
// contains filtered or unexported fields
}
PricesSchedule schedule gas prices for different network version
func NewPricesSchedule ¶
func NewPricesSchedule(forkParams *config.ForkUpgradeConfig) *PricesSchedule
NewPricesSchedule new gasprice schedule from forkParams parameters
func (*PricesSchedule) PricelistByEpoch ¶
func (schedule *PricesSchedule) PricelistByEpoch(epoch abi.ChainEpoch) Pricelist
PricelistByEpoch finds the latest prices for the given epoch
func (*PricesSchedule) SetPricelist ¶ added in v1.2.0
func (schedule *PricesSchedule) SetPricelist(newPrices map[abi.ChainEpoch]Pricelist)
SetPricelist set new prices, for test
