Constants

)
View Source 
const DefaultHamtBitwidth = 5

Default log2 of branching factor for HAMTs. This value has been empirically chosen, but the optimal value for maps with different mutation profiles may differ.

const EpochDurationSeconds = 30

PARAM_SPEC The duration of a chain epoch. Motivation: It guarantees that a block is propagated and WinningPoSt can be successfully done in time all supported miners. Usage: It is used for deriving epoch-denominated periods that are more naturally expressed in clock time. TODO: In lieu of a real configuration mechanism for this value, we'd like to make it a var so that implementations can override it at runtime. Doing so requires changing all the static references to it in this repo to go through late-binding function calls, or they'll see the "wrong" value. https://github.com/filecoin-project/specs-actors/issues/353 If EpochDurationSeconds is changed, update `BaselineExponent`, `lambda`, and // `expLamSubOne` in ./reward/reward_logic.go You can re-calculate these constants by changing the epoch duration in ./reward/reward_calc.py and running it.

Functions

func ActorNameByCode 

func ActorNameByCode(code cid.Cid) string

ActorNameByCode returns the (string) name of the actor given a cid code.

func ConsensusMinerMinPower 

func ConsensusMinerMinPower(p stabi.RegisteredPoStProof) (stabi.StoragePower, error)

The minimum power of an individual miner to meet the threshold for leader election (in bytes). Motivation: - Limits sybil generation - Improves consensus fault detection - Guarantees a minimum fee for consensus faults - Ensures that a specific soundness for the power table Note: We may be able to reduce this in the future, addressing consensus faults with more complicated penalties, sybil generation with crypto-economic mechanism, and PoSt soundness by increasing the challenges for small miners.

func IsBuiltinActor 

func IsBuiltinActor(code cid.Cid) bool

IsBuiltinActor returns true if the code belongs to an actor defined in this repo.

func IsPrincipal 

func IsPrincipal(code cid.Cid) bool

Tests whether a code CID represents an actor that can be an external principal: i.e. an account or multisig. We could do something more sophisticated here: https://github.com/filecoin-project/specs-actors/issues/178

func PoStProofWindowPoStPartitionSectors 

func PoStProofWindowPoStPartitionSectors(p stabi.RegisteredPoStProof) (uint64, error)

Returns the partition size, in sectors, associated with a Window PoSt proof type. The partition size is the number of sectors proved in a single PoSt proof.

func QuantizeUp 

func QuantizeUp(e abi.ChainEpoch, unit abi.ChainEpoch, offsetSeed abi.ChainEpoch) abi.ChainEpoch

Rounds e to the nearest exact multiple of the quantization unit offset by offsetSeed % unit, rounding up. This function is equivalent to `unit * ceil(e - (offsetSeed % unit) / unit) + (offsetSeed % unit)` with the variables/operations are over real numbers instead of ints. Precondition: unit >= 0 else behaviour is undefined

func RequestMinerControlAddrs 

func RequestMinerControlAddrs(rt runtime.Runtime, minerAddr addr.Address) (ownerAddr addr.Address, workerAddr addr.Address, controlAddrs []addr.Address)

func RequireNoErr 

func RequireNoErr(rt runtime.Runtime, err error, defaultExitCode exitcode.ExitCode, msg string, args ...interface{})

Aborts with a formatted message if err is not nil. The provided message will be suffixed by ": %s" and the provided args suffixed by the err.

func RequireParam 

func RequireParam(rt runtime.Runtime, predicate bool, msg string, args ...interface{})

Aborts with an ErrIllegalArgument if predicate is not true.

func RequirePredicate 

func RequirePredicate(rt runtime.Runtime, predicate bool, code exitcode.ExitCode, msg string, args ...interface{})

Aborts with `code` if predicate is not true.

func RequireState 

func RequireState(rt runtime.Runtime, predicate bool, msg string, args ...interface{})

Aborts with an ErrIllegalState if predicate is not true. This method is intended for use like an assertion. Don't use this shorthand for states which are logically possible, as it will hide (non-)coverage of the Abort call from code coverage metrics.

func RequireSuccess 

func RequireSuccess(rt runtime.Runtime, e exitcode.ExitCode, msg string, args ...interface{})

Propagates a failed send by aborting the current method with the same exit code.

func ResolveToIDAddr 

func ResolveToIDAddr(rt runtime.Runtime, address addr.Address) (addr.Address, error)

ResolveToIDAddr resolves the given address to it's ID address form. If an ID address for the given address dosen't exist yet, it tries to create one by sending a zero balance to the given address.

func SealProofSectorMaximumLifetime 

func SealProofSectorMaximumLifetime(p stabi.RegisteredSealProof) (stabi.ChainEpoch, error)

SectorMaximumLifetime is the maximum duration a sector sealed with this proof may exist between activation and expiration

func SealProofWindowPoStPartitionSectors 

func SealProofWindowPoStPartitionSectors(p stabi.RegisteredSealProof) (uint64, error)

Returns the partition size, in sectors, associated with a seal proof type. The partition size is the number of sectors proved in a single PoSt proof.
