The purpose of this interface is to distinguish messages that are
bound to a particular channel_id from those that are not. There is
no reason this ought to be a property of the peer package as it is
entirely determined by the contents of the message itself. Therefore
we move it to the lnwire package so it can be used without having
import cycles elsewhere in the codebase.
Here we notice that the only use of the Peer call on the link is
to find out what the peer's pubkey is. To avoid leaking handles to
IO actions outside the interface we reduce the surface area to
just return the peer's public key.
This commit gives the linter container access to the local machine's
build and module cache, drastically decreasing the run time of
subsequent linter runs (no difference on first run with this change).
In this commit the mission control based fee estimation
is supplemented with a payment probe estimation which can
lead to more accurate estimation results. The probing
utilizes a hop-hint heurisic to detect routes through LSPs
in order to manually estimate fees to destinations behind
an LSP that would otherwise block the payment probe.
In this commit, we bump the version of the master branch to v0.17.99.
This reflects the fact that master will be a super set of all the minor
releases until v0.18, and will also include changes towards v0.18.
In this commit, we update new Taproot related TLVs (nonces, partial sig,
sig with nonce, etc). Along the way we were able to get rid of some
boiler plate, but most importantly, we're able to better protect against
API misuse (using a nonce that isn't initialized, etc) with the new
options API. In some areas this introduces a bit of extra boiler plate,
and where applicable I used some new helper functions to help cut down
on the noise.
Note to reviewers: this is done as a single commit, as changing the API
breaks all callers, so if we want things to compile it needs to be in a
wumbo commit.
This commit adds a new sub command to the wallet that allows using the
new funding option from a template.
Creating a new command is way easier for the user to understand than
adding multiple flags that are only valid in certain combinations.
For the itest in the next commit we'll need to be able to fetch the
input information for an address over RPC. The only piece missing is the
address' index, which we add in this commit. Everything else should be
derivable from the ListAddresses and ListAccounts calls.
In some situations (for example in Taproot Assets), we need to be able
to prove that an address is a bare BIP-0086 address that doesn't commit
to any script. We can do that by providing the BIP-0032 derivation info
and internal key.
In this commit, we add two new methods that simplify usage of an
handling a value wrapped in an Option. Thes methods allow a caller to
force the nil/None check up front, and either obtain the value, or fail
the current execution or test.
This should replace most usages of `UnsafeFromSome` where ever used
today.
In the following commits we'll add a new, third, funding option for
funding PSBTs: It will allow users to specify pre-selected inputs but
still request the wallet to perform coin selection up to the total
output sum amount.
This is a helper function that we will need to accurately determine the
weight of inputs specified in a PSBT.
Due to the nature of P2WSH and script-spend P2TR inputs, we can only
accurately estimate their weights if the full witness is already known.
So this helper function rejects inputs that use a script spend path but
don't fully specify the complete witness stack.
We want to re-use the logic that determines what change amount is left
over depending on whether we add or don't add a change output to a
transaction, respecting the change output's dust limit.
We'll want to be able to tell the coin selection algorithm that we
intend to add any change to an existing output instead of assuming that
a change output is always created.
If we add any left over change to an existing output, we can skip the
dust amount check as we assume the selected existing output already has
a non-dust amount requested (responsibility of the caller to assert).
Before this commit the coin selection logic in the chanfunding package
would always assume that there is a P2WSH funding output and potentially
a P2TR change output. But because we want to re-use the coin selection
for things other than just channel funding, we make the logic more
generic by allowing us to specify both the existing weight of the
transaction (the already known, static parts of the TX) as well as the
type of the potential change output we would use.
