Move enum out of CloseSummary struct for more general use. This does
not change the encoding of the enum, and will only cause compile time
errors for existing clients. This enum has not been included in a
release yet, so we can make this move without much disruption.
In this commit, we add some additional logging of the commitments at
play when we detect a channel closure on-chain. This should help to
debug things more in the future as we don't log the full commitments
anywhere. We also now also print the type of commitment as well, as a
follow up from the recent anchor outputs work. In the near future, as we
implement a dynamic commitments update protocol, always logging the
commitment type as well will likely be useful for debugging purposes.
We'll only do so when we have at least one confirmed advertised channel
with the remote peer. This ensures that our node announcement can
propagate throughout the network even for nodes that were offline when
we initially broadcast it.
There is an alternative in routerrpc now. It doesn't support REST yet,
but the main rpc SendPayment with its bidirectional streaming isn't
usable via REST either.
SendPaymentSync still serves REST users and cannot be deprecated yet.
A PSBT funding flow consists of multiple steps. We add new RPC
messages that can trigger the underlying state machine to transition
to a new state. We also add new response messages that tell the
API user what the current state is.
In case the funding manager detects that a funding flow is requested
to be executed with the help of a PsbtIntent, the normal channel
negotiation with the remote peer is interrupted, as soon as the
accept_channel message was received. With the remote peer's funding
multisig key and our local key, we can derive the funding output
script and its address. This is enough to start the PSBT funding
and signing process which the user will do externally to the daemon.
We add a new funding assembler and intent type that handle channel
funding through the use of a PSBT. The PsbtIntent is in itself a
simple state machine that can be stepped through the process of
assembling the required information for the funding output, verifying
a user supplied PSBT for correctness, accepting a fully signed PSBT
and then assembling the funding wire message.
This commit lets the watchtower automatically create hidden services
by giving it a pointer to a TorController. The server was also slightly
refactored so that it was not the sole owner of the TorController.
