The unit test TestNewBreachRetributionSkipsDustHtlcs triggered a state transition from Bob, even though it was Alice that had added the HTLCs. This is wrong since it will lead to Bob still owing Alice a commitment, which is not accounted for in the unit tests. We add a sanity check that the add heights has been set for all entries found in the logs, and return an error otherwise. This won't happen during normal operation, but it does reveal the mistake in the unit test, which is fixed by making Alice trigger the transition. In addition we resolve a long standing TODO by removing a (purposeful) panic in the channel state machine. Old version of lnd had a bug that could lead to the parent entries being lost during channel restore. A panic was added to get to the bottom of if. This is now fixed, so new nodes shouldn't encounter it. However, to be on the safe side, instead of panicking we return an error back to gracefully exit the channel state machine. |

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.
