In this commit, we make sig job handling when singing a next commitment non-blocking by allowing the shutdown of a channel link to prevent further waiting on sig jobs by the channel state machine. This addresses possible cases where the aux signer may be shut down via a separate quit signal, so the state machine could block indefinitely on receiving an update on a sig job.
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.
