示例1: InitializeKeyspace
// InitializeKeyspace sets the ipns record for the given key to
// point to an empty directory.
// TODO: this doesnt feel like it belongs here
func InitializeKeyspace(ctx context.Context, ds dag.DAGService, pub Publisher, pins pin.Pinner, key ci.PrivKey) error {
emptyDir := &dag.Node{Data: ft.FolderPBData()}
nodek, err := ds.Add(emptyDir)
if err != nil {
return err
}
// pin recursively because this might already be pinned
// and doing a direct pin would throw an error in that case
err = pins.Pin(ctx, emptyDir, true)
if err != nil {
return err
}
err = pins.Flush()
if err != nil {
return err
}
err = pub.Publish(ctx, key, path.FromKey(nodek))
if err != nil {
return err
}
return nil
}示例2: FilterPinned
func FilterPinned(pins pin.Pinner, out chan<- interface{}, cids []*cid.Cid) []*cid.Cid {
stillOkay := make([]*cid.Cid, 0, len(cids))
res, err := pins.CheckIfPinned(cids...)
if err != nil {
out <- &RemovedBlock{Error: fmt.Sprintf("pin check failed: %s", err)}
return nil
}
for _, r := range res {
if !r.Pinned() {
stillOkay = append(stillOkay, r.Key)
} else {
out <- &RemovedBlock{
Hash: r.Key.String(),
Error: r.String(),
}
}
}
return stillOkay
}示例3: ColoredSet
func ColoredSet(ctx context.Context, pn pin.Pinner, ds dag.DAGService, bestEffortRoots []key.Key) (key.KeySet, error) {
// KeySet currently implemented in memory, in the future, may be bloom filter or
// disk backed to conserve memory.
gcs := key.NewKeySet()
err := Descendants(ctx, ds, gcs, pn.RecursiveKeys(), false)
if err != nil {
return nil, err
}
err = Descendants(ctx, ds, gcs, bestEffortRoots, true)
if err != nil {
return nil, err
}
for _, k := range pn.DirectKeys() {
gcs.Add(k)
}
err = Descendants(ctx, ds, gcs, pn.InternalPins(), false)
if err != nil {
return nil, err
}
return gcs, nil
