Functions

func GenerateUnsealedCID 

func GenerateUnsealedCID(proofType abi.RegisteredSealProof, pieces []abi.PieceInfo) (cid.Cid, error)

Types

type ExternPrecommit2 added in v1.25.2 

type ExternPrecommit2 func(ctx context.Context, sector storiface.SectorRef, cache, sealed string, pc1out storiface.PreCommit1Out) (sealedCID cid.Cid, unsealedCID cid.Cid, err error)

func MakeExternPrecommit2 added in v1.25.2 

func MakeExternPrecommit2(command string) ExternPrecommit2

MakeExternPrecommit2 creates an implementation of ExternPrecommit2 backed by an external command specified by the command string.

The command will be called with a number of environment variables set: * EXTSEAL_PC2_SECTOR_NUM: the sector number * EXTSEAL_PC2_SECTOR_MINER: the miner id * EXTSEAL_PC2_PROOF_TYPE: the proof type * EXTSEAL_PC2_SECTOR_SIZE: the sector size in bytes * EXTSEAL_PC2_CACHE: the path to the cache directory * EXTSEAL_PC2_SEALED: the path to the sealed sector file (initialized with unsealed data by the caller) * EXTSEAL_PC2_PC1OUT: output from rust-fil-proofs precommit1 phase (base64 encoded json)

The command is expected to: * Create cache sc-02-data-tree-r* files * Create cache sc-02-data-tree-c* files * Create cache p_aux / t_aux files * Transform the sealed file in place
