When the funding transaction has been confirmed, the FundingLocked
message is sent by the peers to each other so that the existence of the
newly funded channel can be announced to the network.
This commit also removes the SingleFundingOpenProof message.
This commit modifies the prior HTLCSettleRequest to more closely match
the UpdateFufillHTLC defined within the specification. The only
semantic change is the move from a slice of pre-images (for “multi-sig”
LN) to a single payment preimage.
This commit morphs the prior CancelHTLC into the new UpdateFailHTLC
message and also gets rid of the obsolete HLTCAddReject message while
we’re at it.
The primary change from the CancelHTLC message to the UpdateFailHTLC
message is that the CancelReason is now simply called Reason and that
it’s now an opaque encrypted set of bytes. With this update the failure
messages are now more flexible (they can even carry new
ChannelUpdate’s) and also don’t reveal the exact cause of failure to
intermediate nodes.
This commit renames and modifies the CommitSignature message to more
closely match the CommitSig message defined within the current set of
draft specifications.
The major change within the new message is that we now longer
explicitly specify the update log index of the remote node that this
signature covers. This is due to the fact the revocation message now
also double as acknowledgements of the remote parties recevied
commitment update messages.
This commit renames the prior CommitRevocation message to RevokeAndAck
in order to better align the set of wire messages implemented by the
`lnwire` message with those currently defined within the specification.
'init' message is the first message reveals the features supported or required
by this node. Nodes wait for receipt of the other's features to simplify error
diagnosis where features are incompatible. This message will help negotioate the
the features which are supported by both sides.
This commit adds a new error type to the `lnwire` package:
`UnknownMessage`. With this error we can catch the particular case of a
an error during reading that encounters a new or unknown message. When
we encounter this message in the peer’s readHandler, we can now
gracefully handle it by just skipping to the next message rather than
closing out the section entirely.
This puts us a bit closer to the spec, but not exactly as it has an
additional constraint that we can only ignore a new message if it has
an odd type. In a future release, we’ll modify this code to match the
spec as written.
This commit modifies the login of sent/recv’d wire messages in trace
mode in order utilize the more detailed, and automatically generated
logging statements using pure spew.Sdump.
In order to avoid the spammy messages due to spew printing the
btcec.S256() curve paramter within wire messages with public keys, we
introduce a new logging function to unset the curve paramter to it
isn’t printed in its entirety. To insure we don’t run into any panics
as a result of a nil pointer defense, we now copy the public keys
during the funding process so we don’t run into a panic due to
modifying a pointer to the same object.
This commit removes the older routing/discovery messages from the
unwire package, as we’ll be converging towards BOLT07 in the near-term.
In the mid to far term we’ll be revisiting integrating Flare into the
newer scheme in order to take advantage of its scaling characteristics.
Use [33]byte for graph vertex representation.
Delete unneeded stuff:
1. DeepEqual for graph comparison
2. EdgePath
3. 2-thread BFS
4. Table transfer messages and neighborhood radius
5. Beacons
Refactor:
1. Change ID to Vertex
2. Test use table driven approach
3. Add comments
4. Make graph internal representation private
5. Use wire.OutPoint as EdgeId
6. Decouple routing messages from routing implementation
7. Delete Async methods
8. Delete unneeded channels and priority buffer from manager
9. Delete unneeded interfaces in internal graph realisation
10. Renamed ID to Vertex
This commit adds Ping and Pong messages to the suite of lnwire
messages. The usage of these messages within the daemon are similar to
the usage of Bitcoin’s ping/pong messages. Pings are to be sent
periodically with a random nonce to check connection activity and also
to gauge latency. Pong’s are to be sent in reply to ping messages,
echo’ing the same nonce used.
This commit adds a few workarounds in order to concurrently support the
REST proxy as well as the regular gRPC interface. Additionally,
concrete support for the following RPC calls has been added:
GetTransactions, SubscriptTransactions, SubscribeInvoices, and
NewWitnessAddress.
This commit removes the previous HTLC timeout in message in favor of a
HTLC cancel message. Within the protocol, a timeout message would never
be sent backwards along the route as in the case of an HTLC timeout
before/after the grace period, the course of action taken would be to
broadcast the current commitment transaction unilaterally on-chain.
This commit integrates BitFury's current routing functionality into lnd. The
primary ochestration point for the routing sub-system in the routingMgr. The
routingMgr manages all persistent and volatile state related to routing within
the network.
Newly opened channels, either when the initiator or responder are inserted into
the routing table once the channel is fully open. Once new links are inserted
the routingMgr can then perform path selection in order to locate an "optimal"
path to a target destination.
* Structs and wire messages for HTLCs
* Wire protocol for a state machine with no blocking(!!!)
(I will write the state machine)
TL;DR: Can do multiple HTLC modifications in-flight, dead simple wire
protocol. Both sides can update their Commitments unliaterally without
waiting for the other party's signature. Will have basic/preliminary
notes in the README
* Added **swp to .gitignore because of vim annoyances
