This commit redoes the API and semantics of processFeeUpdate to make it consistent with the semantics of it's sister functions. This is part of an ongoing series of commits to remove mutateState arguments pervasively from the codebase. As with the previous commit this makes state mutation the caller's responsibility. This temporarily increases code duplication at the call-sites, but this will unlock other refactor opportunities.
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.
