This commit adds a module for a finite state machine. The goal of the
module is to provide a simple, easy to use, and easy to understand
finite state machine. The module is designed to be used in future
loop subsystems. Additionally a state visualizer is provided to
help with understanding the state machine.
This commit ensures that we don't even check for the existence of
the loop.db file if loop_sqlite.db already present. This is to ensure
that on systems that may by any trigger restore deleted files we don't
try to re-run migration which would otherwise make loopd unable to start
up properly.
Previously we would exclusively pass the autoloop boolean to multiple
functions while they had directly access to the manager's parameters.
With this commit we remove this explicit flag from the various function
interfaces and retrieve the value directly from the parameters.
Adds the easy autoloop function which executes a budget update and the
best easy-autoloop swap. The easy-autoloop function re-uses functions
used in the normal autoloop that relate to on-going swaps and traffic
summary.
This commit bumps LND and lndclient to make it possible to upgrade
taproot HTLC construction with a MuSig2 version. This is required to
support both old (MuSig2 0.4) and new (MuSig2 1.0) clients.
This commit is a refactor of how we construct htlcs to make it possible
to pass in internal keys for the sender and receiver when creating P2TR
htlcs. Furthermore the commit also cleans up constructors to not pass in
script versions and output types to make the code more readable.
This commit removes all code related to NP2WSH htlcs. These were
historically used when segwit adoption was very sporadic and are not
used anywhere anymore. Some historical swaps stored in the DB may be
listed with incorrect htlc adresses from here on.
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)
