This updates the RPCAcceptor to send the correct commitment type
even if the zero-conf or scid-alias channel types are set. This also
adds two bools to the ChannelAcceptRequest struct that denotes whether
the funder set the zero-conf and scid-alias channel types.
In this commit, we catch up our logic with the latest version of the
spec that removed support for normal p2kh and p2sh addresses for co-op
closes, in order to make dust calculations more uniform.
In this commit, we add awareness of the option_shutdown_anysegwit that
permits both sides to send newer segwit based addresses. This'll
eventually enable us to send taproot addresses for co-op close.
With this change, transactions created via craftSweepTx will be
standard. Previously, p2wsh/p2pkh scripts passed in via SendCoins would
be weighted as p2wpkh scripts. With a feerate of 1 sat/vbyte,
transactions returned would be non-standard. Luckily, the critical
sweeper subsystem only used p2wpkh scripts so this only affected
callers from the rpcserver.
Also added is an integration test that fails if SendCoins manages
to generate a non-standard transaction. All script types are now
accounted for in getWeightEstimate, which now errors if an unknown
script type is passed in.
The bitcoind .cookie contains an autogenerated user (__cookie__) and
password (random string), which can be used instead of the rpc user name
and password. This commit allows for running against bitcoind without
having to access bitcoin.conf like in the case for pure
user/password/zmq configuration.
In this commit, we add a check during normal node construction to see if
the backend node supports Taproot. If it doesn't, then we want to
shutdown and force the user to take note.
To check if the node supports Taproot, we'll first try the normal
getblockchaininfo call. If this works, cool, then we can rely on the
value. If it doesn't, then we'll fall back to the getdeploymentinfo call
which was added in a recent version of bitcoind [1]. Newer versions of
bitcoind might also have this call, and the getblockchaininfo call, but
not actually populate the softforks field [2]. In this case, we'll fall
back, and we also account for the case when the getblockchaininfo RPC is
removed all together.

In this commit, we add a test case to exercise the fact that if we
request a confirmation notification with the raw block, then it includes
one. We add this to the existing test that uses the conf ntfn rpc call
for simplicity.
In this commit, we add a new option for the existing confirmation
notification system that optionally allows the caller to specify that a
block should be included as well.
The only quirk w/ the implementation here is the neutrino backend:
usually we get filtered blocks, we so need to first fetch the block
again so we can deliver the full block to the notifier. On the notifier
end, it'll only be checking for the transactions we care about, to
sending a full block doesn't affect the correctness.
We also extend the `testBatchConfirmationNotification` test to assert
that a block is only included if the caller specifies it.
In this commit, we parse the new max fee field, and pass it through the
switch, all the way to the peer where it's ultimately passed into the
chan closer state machine.
In this commit, we remove the raw channel state machine pointer from the
chan closer and instead replace that with an interface that captures
*just* the methods we need in order to do the co-op close dance.
This is a preparatory refactoring for some upcoming unit tests.
In this commit, we stop clamping the ideal fee rate to the commitment
fee of the channel. This catches us up to this PR of the spec:
https://github.com/lightning/bolts/pull/847.
We also do away with the old 3x ideal fee "max fee", and replace that
with an explicit max fee. This new max fee will either be the default
multiplier of the ideal fee, or a new user specified max fee value.
