Functions

func FetchWithTemp

func FetchWithTemp(ctx context.Context, urls []string, dest string, header http.Header) (string, error)

FetchWithTemp fetches data into a temp 'fetching' directory, then moves the file to destination The set of URLs must refer to the same object, if one fails, another one will be tried.

func FileTypeFromString

func FileTypeFromString(t string) (storiface.SectorFileType, error)

Types

type DefaultPartialFileHandler

type DefaultPartialFileHandler struct{}

DefaultPartialFileHandler is the default implementation of the PartialFileHandler interface. This is probably the only implementation we'll ever use because the purpose of the interface to is to mock out partial file related functionality during testing.

Reader returns a reader for an unsealed piece at the given offset in the given sector. If the Miner has the unsealed piece locally, it will return a reader that reads from the local copy. If the Miner does NOT have the unsealed piece locally, it will query all workers that have the unsealed sector file to know if they have the unsealed piece and will then read the unsealed piece data from a worker that has it.

Returns a nil reader if : 1. no worker(local worker included) has an unsealed file for the given sector OR 2. no worker(local worker included) has the unsealed piece in their unsealed sector file. Will return a nil reader and a nil error in such a case.
