func (i *MemIndex) StorageBestAlloc(ctx context.Context, allocate storiface.SectorFileType, ssize abi.SectorSize, pathType storiface.PathType, miner abi.ActorID) ([]storiface.StorageInfo, error)

StorageBestAlloc selects the best available storage options for allocating a sector file. It takes into account the allocation type (sealing or storage), sector size, and path type (sealing or storage).

The method first estimates the required space for the allocation based on the sector size and path type. It then iterates through all available storage options and filters out those that cannot be used for the given path type. It also filters out storage options that do not have enough available space or have not received heartbeats within a certain threshold.

The remaining storage options are sorted based on their available space and weight, with higher availability and weight being prioritized. The method then returns the information of the selected storage options.

If no suitable storage options are found, it returns an error indicating that no good path is available.

Parameters: - ctx: the context.Context object for cancellation and timeouts - allocate: the type of allocation (sealing or storage) - ssize: the size of the sector file - pathType: the path type (sealing or storage)

Returns: - []storiface.StorageInfo: the information of the selected storage options - error: an error indicating any issues encountered during the process

The method first acquires a read lock on the MemIndex to ensure thread-safety. It then checks if the storage ID exists in the stores map. If not, it returns an error indicating that the sector store was not found.

Finally, it returns the storage information of the selected storage.

Parameters: - ctx: the context.Context object for cancellation and timeouts - id: the ID of the storage to retrieve information for

Returns: - storiface.StorageInfo: the storage information of the selected storage ID - error: an error indicating any issues encountered during the process

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.
