type PullFilter ¶

type PullFilter interface {
	ShouldPull(ctx context.Context, objectId string, rootChange *treechangeproto.RawTreeChangeWithId, heads []string) bool
}

PullFilter is an optional extension of the registered TreeSyncer. When a head update arrives for a tree that does not exist locally, objectsync consults it before queueing the fetch: returning false swallows the update and the tree is not pulled. rootChange is the tree's raw root (carried by every head update; its header — including changeType — is cleartext) and heads are the sender's current heads. TreeSyncers that do not implement the interface keep the default always-pull behavior.

type TreeSyncer ¶

type TreeSyncer interface {
	app.ComponentRunnable
	StartSync()
	StopSync()
	ShouldSync(peerId string) bool
	SyncAll(ctx context.Context, p peer.Peer, existing, missing []string) error
}
