This commit moves common logic used to calculate the state of a commitment after applying a set of HTLC updates, into the new method computeView. This method can be used when calculating the available balance, validating the sanity of a commitment after applying a set of updates, and also when creating a new commitment, reducing the duplication of this logic.
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 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.
