This commit fixes an existing bug within extractHtlcResolutions. The prior code would use an index to assign the returned OutgoingHtlcResolutions into a single slice. However, this is invalid as there are two cases where an HTLC might be skipped: if it’s an incoming HTLC, or if the HLTC itself is dust from the PoV of the commitment chain. To fix this, we now instead use append to add items to the slice. This ensure that we don’t have any “empty” items in between fully populated items.
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.
