In this commit, we add an additional degree of isolation to the set of integration tests. A bug was recently fixed to ensure that the wallet always starts rescans from _after_ it's birthday. In the past it would miss some funds that were deposited _right_ before the birthday of the wallet. Fixing this bug exposed a test flake wherein the btcd node would itself rescan back and collect some of the funds that were last sent to the bitcoind node. In order to fix this, we now ensure that each backend will use a unique HD seed such that the tests are still deterministic for each backend and role.
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.
