Store the server's static loop-in confirmation-risk decision and the time it
was received. This lets recovered swaps reconstruct whether payment waiting had
already started and how much of the payment timeout remains.
Wire notification handling to persist accepted and rejected decisions before
caching and forwarding them. If the swap row is not present yet, the
notification is still cached so the per-swap waiter can replay and store the
decision later.
Recover accepted decisions by starting the payment deadline from the persisted
decision time, and recover rejected decisions by canceling the invoice and
failing the swap instead of waiting forever.
Surface static-address deposits as soon as they appear in the wallet instead
of waiting for the old six-confirmation readiness threshold.
Reconcile the wallet view on startup, on each block, and on the polling ticker
so mempool deposits are created immediately. Backfill the first confirmation
height once those outputs confirm, protect unconfirmed deposits from expiry,
and mark vanished unconfirmed outpoints as Replaced so RBFed-away deposits stop
showing up in RPCs.
Expose the new state through static-address RPCs by deriving availability and
summary totals from stored deposit state, reporting sensible expiry data for
unconfirmed outputs, and hiding Replaced records from normal listings.
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.
This data is not used by Batcher since commit
"sweepbatcher: load swap from loopdb, not own store".
Now sweepbatcher.Store depends only on tables sweeps and sweep_batches
and does not depend on swaps, loopout_swaps and htlc_keys, making it
easier to reuse.
