Network now signals when it successfully listens on some address
or when an address shuts down. This will be used to establish and
close nat port mappings. It could also be used to notify peers
of address changes.
I think it's time to move a lot of the peer-to-peer networking
but-not-ipfs-specific things into its own package: p2p.
This could in the future be split off into its own library.
The first thing to go is the peer.
Had to change the network interface from DialPeer(peer.ID) to
DialPeer(peer.PeerInfo), so that addresses of a provider are
handed to the network.
@maybebtc and I are discussing whether this should go all the
way down to the network, or whether the network _should always
work_ with just an ID (which means the network needs to be
able to resolve ID -> Addresses, using the routing system.
This latter point might mean that "routing" might need to
break down into subcomponents. It's a bit sketchy that
the Network would become smarter than just dial/listen and
I/O, but maybe there's a distinction between net.Network,
and something like a peernet.Network that has routing
built in...)
this is a major refactor of the entire codebase
it changes the monolithic peer.Peer into using
a peer.ID and a peer.Peerstore.
Other changes:
- removed handshake3.
- testutil vastly simplified peer
- secio bugfix + debugging logs
- testutil: RandKeyPair
- backpressure bugfix: w.o.w.
- peer: added hex enc/dec
- peer: added a PeerInfo struct
PeerInfo is a small struct used to pass around a peer with
a set of addresses and keys. This is not meant to be a
complete view of the system, but rather to model updates to
the peerstore. It is used by things like the routing system.
- updated peer/queue + peerset
- latency metrics
- testutil: use crand for PeerID gen
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 some randomness and hash it. to
generate proper keys and an ID, use:
sk, pk, _ := testutil.RandKeyPair()
id, _ := peer.IDFromPublicKey(pk)
Also added RandPeerIDFatal helper
- removed old spipe
- updated seccat
- core: cleanup initIdentity
- removed old getFromPeerList
remove 'adapter' concept
instead, describe the component as the bitswap network
it's still an adapter, but it's just not necessary to describe it as
such
