Variables

var SeededRand *rand.Rand

var ZeroLocalTCPAddress ma.Multiaddr

ZeroLocalTCPAddress is the "zero" tcp local multiaddr. This means:

/ip4/127.0.0.1/tcp/0

Functions

func NewSeededRand

func NewSeededRand(seed int64) *rand.Rand

func RandLocalTCPAddress

func RandLocalTCPAddress() ma.Multiaddr

RandLocalTCPAddress returns a random multiaddr. it suppresses errors for nice composability-- do check the address isn't nil.

Note: for real network tests, use ZeroLocalTCPAddress so the kernel assigns an unused TCP port. otherwise you may get clashes. This function remains here so that p2p/net/mock (which does not touch the real network) can assign different addresses to peers.

func RandPeerID

func RandPeerID() (peer.ID, error)

RandPeerID generates random "valid" peer IDs. it does not NEED to generate keys because it is as if we lost the key right away. fine to read randomness and hash it. to generate proper keys and corresponding PeerID, use:

sk, pk, _ := testutil.RandKeyPair()
id, _ := peer.IDFromPublicKey(pk)

func RandPeerIDFatal

func RandPeerIDFatal(t testing.TB) peer.ID

func RandTestKeyPair

func RandTestKeyPair(bits int) (ci.PrivKey, ci.PubKey, error)

func SeededTestKeyPair

func SeededTestKeyPair(seed int64) (ci.PrivKey, ci.PubKey, error)

func ThreadSafeCloserMapDatastore

func ThreadSafeCloserMapDatastore() ds2.ThreadSafeDatastoreCloser
