Don't auto-fail offers payments pre-HTLC lock in - #4078
Conversation
Previously, we had a bug that particularly affected async payments where if an
outbound payment was in the state {Static}InvoiceReceived and there was a call
to process_pending_htlc_forwards, the payment would be automatically abandoned.
We would behave correctly and avoid abandoning if the payment was awaiting an
invoice, but not if the payment had an invoice but the HTLCs weren't yet locked
in.👋 Thanks for assigning @joostjager as a reviewer! |

First I thought InvoiceReceived isn't necessary, because the payment is initiated immediately after receiving the invoice. But on a closer look, I think there are also similar gaps that require this check. There is also manual bolt12 invoice payment. No test coverage though I think.
