In line with previous commits we are progressively removing the mutateState argument from this call stack for a more principled software design approach. NOTE FOR REVIEWERS: We take a naive approach to updating the tests here and simply take the functionality we are removing from evaluateHTLCView and run it directly after the function in the test suite. It's possible that we should instead remove this from the test suite altogether but I opted to take a more conservative approach with respect to reducing the scope of tests. If you have opinions here, please make them known.
lnwallet
The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
