In this commit, we move the initialization of the server into the
funding manager itself. We do this as it's no longer the case that _any_
RPC needs to access the funding manager. In the past, this was the
only reason that the funding manager was instantiated outside of the
server: to be able to respond to queries _before_ the server was
started.
This change also fixes a bug as atm, the funding manager will try to
register for notifications _before_ the ChainNotifier itself has fully
started.
In this commit, we modify the test to explitlcy give the neutrino
backend more time to catch up compared to the RPC backends. We do this
as a recent change has been made in the neutrino backend to wait for the
filter headers to finish syncing before proceeding with the rescan
itself. As a result, we'll need to account for this in the test and
sleep enough to give the backend a chance to catch up.
In this commit, we update the convertToSecondLevelRevoke function to
also upgrade the second level pkScript as well. This is required as
we'll need to use this for a confirmation notification once we sweep the
output in the case that the remote party goes to the second layer.
In this commit, we update the NewBreachRetribution method to include
pkScripts for htlc outputs. We do this now, as the breach arbiter will
need the raw pkScript when attempting to request spend notifications for
each HTLC.
In this commit, we ensure that the neutrino backend meets the target
interface, and also we update the API usage for the internal neutrino
rescan struct to use the new InputWithScript struct.
In this commit, we update the existing UpdateFilter method to take the
new channeldb.EdgePoint struct in place of the prior wire.OutPoint. We
must do this as the caller now typically has this type due to the
preparation to enable lnd to be able to be compatible with the new
neutrino protocol.
In this commit, we update the ChannelView method to be compatible with
the new set of interfaces that require the script to be passed in in
addition to the outpoint. In order to do this, we introduce a new
EdgePoint struct which packages together a channel point along with the
funding pkScript. Along the way, we've copied over a utility method from
the lnwallet package to avoid having to deal with an import cycle.
In this commit, we update the neutrino backend for the ChainNotifier to
use the new API which requires that callers pass the outpoint along with
the pkScript to be notified of any spends.
In this commit, we update the RegisterSpendNtfn method to also take the
prev output script of the item that we're attempting to watch for. This
change is required due to the recent modifications in the neutrino
protocol (BIP 158 + 157). With the new protocol, we'll match on the
script, but then dispatch notifications based on the precise outpoint
that matches.
In this commit, we export WitnessScriptHash and GenMultiSigScript as
external sub-systems may now need to use these methods in order to be
able to watch for confirmations based on the script of a transaction.
