Store server confirmation-risk decisions with static loop-in swaps and
recover accepted payment-deadline timers after restart. Wire
notification persistence through loopd so recovered swaps do not lose
pending risk state.
Deduplicate notification fanout cache entries by swap hash.
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.
Add a TxOutChecker interface for testing whether an original deposit
outpoint is still available before a static loop-in signs its HTLC
transaction.
Implement the checker using lnd's wallet transaction view so wallet-known
spends, including mempool spends when requested, cause the outpoint to be
reported unavailable.
Treat lnd wallet view as the source of spendable static-address
outputs while keeping historical deposit records in the DB. Reconcile
active FSMs against the current wallet view and reactivate known
deposits when their outpoints are visible again.
Refresh deposits before selection, withdrawal, loop-in, and channel-open
paths, and filter list and summary responses through the live active set
so stale Deposited records are not exposed as available funds.
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.
