func ColoredSet ¶

func ColoredSet(ctx context.Context, pn pin.Pinner, ds dag.DAGService, bestEffortRoots []key.Key) (key.KeySet, error)

func Descendants ¶

func Descendants(ctx context.Context, ds dag.DAGService, set key.KeySet, roots []key.Key, bestEffort bool) error

func GC ¶

func GC(ctx context.Context, bs bstore.GCBlockstore, pn pin.Pinner, bestEffortRoots []key.Key) (<-chan key.Key, error)

GC performs a mark and sweep garbage collection of the blocks in the blockstore first, it creates a 'marked' set and adds to it the following: - all recursively pinned blocks, plus all of their descendants (recursively) - bestEffortRoots, plus all of its descendants (recursively) - all directly pinned blocks - all blocks utilized internally by the pinner

The routine then iterates over every block in the blockstore and deletes any block that is not found in the marked set.
