18:23:50 +0200 Subject: [PATCH 3/3] Improvements and bug fixes to taproot channels (#814) * Always use Taproot channel type It was missing in several cases, and the `OpenChannel` command allowed using other channel types. * nit: refactor scripts and transactions * Refactor commitments We refactor `Commitments.kt` to better match `eclair` and clean up pattern matching (use exhaustive, future-proof pattern matching). We also remove alternative feerate sigs, which aren't necessary anymore since we can now use package relay. The ACINQ node will stop sending `update_fee` and will keep the commitment feerate at `1 sat/byte`. * Refactor `interactive-tx` management Error handling was missing from a few places (incorrectly assuming that nonces were already provided and signature couldn't fail). We also use exhaustive pattern matching everywhere, and clean-up the nonces and funding tx index parameters. We also revert some formatting nits, which make the file inconsistent. * Fix closing RBF nonce management The nonce management was incomplete for mutual close RBF (see changes to `Negotiating.kt`). We must add unit tests to catch those bugs. Mutual close was also not working properly because `revoke_and_ack` nonces weren't taken into account in the `ShuttingDown` state. We also refactor the nonce fields in the various channel states, in which some nonces where unnecessary (e.g. already contained in the `shutdown` message). We make the ordering of fields consistent: `remoteNextCommitNonces` always comes right after `commitments`, since it should always be filled (for taproot channels) and is necessary to update the `commitments`. * Switch tests to taproot channel type We switch almost all existing tests to use the taproot channel type. We fix a few bugs found by the existing test suite: - preimage extraction from HTLC transactions was missing - channel_ready didn't contain local commit nonces - channel_reestablish nonces had an off-by-one in the commit index --- .../kotlin/fr/acinq/lightning/NodeParams.kt | 1 + .../fr/acinq/lightning/channel/Commitments.kt | 146 +++------ .../fr/acinq/lightning/channel/Helpers.kt | 116 +++---- .../acinq/lightning/channel/InteractiveTx.kt | 300 ++++++++---------- .../acinq/lightning/channel/states/Channel.kt | 142 +++++---- .../acinq/lightning/channel/states/Closed.kt | 3 +- .../acinq/lightning/channel/states/Closing.kt | 3 +- .../lightning/channel/states/Negotiating.kt | 38 ++- .../acinq/lightning/channel/states/Normal.kt | 63 ++-- .../acinq/lightning/channel/states/Offline.kt | 8 +- .../lightning/channel/states/ShuttingDown.kt | 19 +- .../acinq/lightning/channel/states/Syncing.kt | 61 ++-- .../channel/states/WaitForAcceptChannel.kt | 11 +- .../channel/states/WaitForChannelReady.kt | 12 +- .../channel/states/WaitForFundingConfirmed.kt | 30 +- .../channel/states/WaitForFundingCreated.kt | 2 -
