In this commit we bump the minimum LND version required to run loopd to
v0.15.1-beta in order to ensure that the underlying chain backend
supports taproot (https://github.com/lightningnetwork/lnd/pull/6798)
In this commit we add the version 3 htlc, which is implemented with
taproot script spending the two payment paths: the claim path case, and
the timeout case.
Since the code for creating and using a macaroon service is the same for
multiple projects (pool, loop, litd etc), the code has been unified in
lndclient. So this commit removes the macaroon service code and instead
uses the lndclient code.
With this PR we include the final version of the lnd v0.14.0-beta
release to ensure compatibility.
The rationale for choosing Loop version 0.15.1 instead of 0.16.0 is that
this doesn't add any major new features.
To allow code with more up-to-date dependencies to import loop, we
bump our lndclient version. The minimum loop version remains 11.1
since we're not using any new apis.
The version v0.10.1-beta of lnd is quite old with v0.13.0-beta just
being published as RC2. Maintaining backward compatibility in the
lndclient library is quite an effort. We decided to merge the v0.11.1
branch into master meaning that all our projects now have this minimum
version requirement.
This commit bumps the _compile time_ version of lnd to v0.13.0-beta.rc2.
This does not have an effect on the user, the run time backward compatibility
will be preserved. Only the next commit will bump that minimum version.
Since the lsat code was copied over to aperture a while ago for other
projects to use as well, we should migrate over to that shared code
also. This will give us the recently added "remove token if payment
failed and try again" feature for free along with some other small
updates to the lsat package.
We update to the latest lndclient that now requires a label when
publishing an on-chain transaction. Instead of just adding an empty
string, we use the proper labels added in a previous commit.
Add a dated fee budget to our swap suggestions. This budget only applies
to automatically dispatched swaps (which will be added in later
commits). We choose to apply the fee budget to our suggestions so that
they perfectly replicate what the autolooper would do. The budget has a
start date so that it can be refreshed once it has been used up over a
period (rather than having to endlessly increase it).
To make sure we can use the latest version of loop in LiT, we need to
make sure loop compiles against the actual v0.11.1 branch of lnd. There
were some conflicting changes to the macaroon service that didn't make
it to the branch that we need to roll back. Those changes don't affect
loop at all as we were always using the default root key ID anyway.
We update to the newest version of lnd so we can use the updated
macaroon service.
NOTE: This is a compile time dependency update only, no RPC level update
is required.
We need the newer version of lndclient to get our synced to chain
state. This requires changes to our test mock, so it is separated
into a different commit. Since lndclient is expanding to be used in
projects other than loop, the client interface is embedded in our
mock rather than implementing functions we do not need. Functions that
we already use in tests are updated accordingly.
Note that while this commit bumps us to a version of lndclient that
defaults to requiring lnd 0.11, we do not bump our required version
yet because we are not using any new endpoints.
Once we have revealed our preimage to the world with a sweep attempt,
we can safely push our preimage to the server to speed up on chain
claim.
Rather than rely on the server, we use the state of our invoice in lnd
to determine whether we should continue trying to push the preimage to
the server.
