Record replayed server risk decisions through the loop-in store,
recover accepted payment-deadline timers using the persisted decision
time, and handle persisted rejections on restart. This lets recovered
static loop-ins keep pending confirmation-risk state instead of
restarting payment timing from scratch.
Subscribe to static loop-in confirmation-risk notifications before
starting the payment deadline. Start that deadline only after server
acceptance or the legacy confirmation fallback, and cancel the swap
invoice when the server rejects the risk wait. Refresh selected
deposits before the legacy fallback so recovered monitors use current
confirmation heights.
Refresh the active static-address deposit set against lnd's wallet view
before quote, loop-in, withdrawal, channel-open, and autoloop selection
paths. This prevents stale persisted Deposited records from being
selected after replacement, reorg, or an external spend.
Add a TxOutChecker interface for checking whether a selected deposit
outpoint is still available before signing the HTLC transaction.
Back the implementation with lnd wallet transaction data so known
confirmed and mempool spends mark the outpoint unavailable.
The Parameters struct describes the keys, expiry and pkScript that
define the static address script, so its natural home is the script
package. Moving it there lets staticutil drop its dependency on the
address package and lets callers reuse a single type alongside
script.StaticAddress and script.NewStaticAddress.
No behavior change.
Closes#1056
In this commit we add a new function SelectDeposits
to the loop-in manager. It coin-selects deposits that
meet an arbitrary swap amount provided by the client.
We have to ensure that the server creates the correct
change outputs for the htlc- and sweepless sweep
transactions.
This commit adds the listening for sweep requests from the server.
On a sweep request the loopin manager will fetch the loop in from the
db, do sanity and safety checks and then sign the psbt for the input
and send it back to the server.
