Create a fresh static change address for fractional loop-ins and persist
its key locator with the selected HTLC outpoint. Recovery reconstructs
the same change output instead of returning funds to the legacy root
address.
Join each selected deposit with its persisted static-address row during
loop-in recovery. Hydrate legacy rows as needed so restored swaps retain
the scripts and key locators required for signing.
Associate every deposit with the static address parameters that created
it. This lets restored deposits recover the correct script and signing
keys instead of assuming the legacy root address.
Add schema, sqlc queries, store fields, and SqlStore support for
recording server confirmation-risk decisions with static loop-in swaps.
Store the decision timestamp so payment-deadline recovery can
reconstruct elapsed time after restart.
Enable staticcheck's SA1019 check in golangci-lint so deprecated
identifiers are caught in CI.
Replace deprecated standard library and bbolt APIs with their current
equivalents. Keep intentional compatibility reads and writes of
deprecated Loop RPC fields behind narrow nolint annotations, because
older clients and persisted liquidity parameters still depend on those
fields.
Added option WithSkippedTxns, which has one historical problematic tx by default.
Sweeps originating from these transactions are omitted when reading from DB.
loopdb: add column sweep_batches.cancelled and replaced DropBatch with
CancelBatch. It is needed, because sweep.batch_id is a foreign key to batch.
Changed StoreMock.InsertSweepBatch not to reuse batch_id. This is needed by
the test, which checks that new batch has fresh ID.
Don't copy values of ID column from sweeps to sweeps2 and let it auto-assign
values there. This is needed for the sequencer for that column to be up-to-date
with the values.
SwapHash used to be a key in the sweeps table. Now the key is outpoint which
replaces columns outpoint_txid and outpoint_index. In-memory structures and unit
tests were also updated to use outpoint as key. Outpoint is truly unique.
Deposit schema extension with a withdrawal
sweep address. If the user selects a deposit
for withdrawal the destination address of the
sweep is stored here.
Previously, when handling a sweep we assumed that if a sweep status
was completed, the parent batch was also finished. However, since the
batch confirmation status depends on three on-chain confirmations, it
is possible that a spend notifier was started for a sweep of an active
batch. The notifier would fetch the parent batch from the database, but
because we incorrectly assumed that the parent was confirmed (when it
was not), the DB call would fail with a 'no rows returned' error.
This failure would cause the sweep to fail and the sweep batcher to
stop, resulting in a permanent failure state.
Provide a wrapped store type, exposing ExecTx method with a subset
interface in the callback argument. BaseDB interfaces in instantout,
reservation and sweepbatcher use ExecTx with their subset Querier
instead of whole sqlc.Querier (*sqlc.Queries).
This is needed to make the packages more reusable, so they don't
depend on methods of *sqlc.Queries they don't use.
Previously we may have stored negative costs for some loop out swaps
which this commit attempts to correct by fetching all completed swap,
calculating the correct costs and overriding them in the database.
