* lnwallet: fix log output msg The log message is off by one. * htlcswitch: fail channel when revoking it fails. When the revocation of a channel state fails after receiving a new CommitmentSigned msg we have to fail the channel otherwise we continue with an unclean state. * docs: update release-docs * htlcswitch: tear down connection if revocation processing fails If we couldn't revoke due to a DB error, then we want to also tear down the connection, as we don't want the other party to continue to send updates. That may lead to de-sync'd state an eventual force close. Otherwise, the database might be able to recover come the next reconnection attempt. * kvdb: use sql.LevelSerializable for all backends In this commit, we modify the default isolation level to be `sql.LevelSerializable. This is the strictness isolation type for postgres. For sqlite, there's only ever a single writer, so this doesn't apply directly. * kvdb/sqlbase: add randomized exponential backoff for serialization failures In this commit, we add randomized exponential backoff for serialization failures. For postgres, we''ll his this any time a transaction set fails to be linearized. For sqlite, we'll his this if we have many writers trying to grab the write lock at time same time, manifesting as a `SQLITE_BUSY` error code. As is, we'll retry up to 10 times, waiting a minimum of 50 miliseconds between each attempt, up to 5 seconds without any delay at all. For sqlite, this is also bounded by the busy timeout set, which applies on top of this retry logic (block for busy timeout seconds, then apply this back off logic). * docs/release-notes: add entry for sqlite/postgres tx retry --------- Co-authored-by: ziggie <ziggie1984@protonmail.com> |

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.
