Mike Hearn aff5f140fb Payment channels: add payment acks. ... Add a new PAYMENT_ACK message to the protocol. Make incrementPayment return a future that completes when the server has acknowledge the balance increase. Also, prevent users from overlapping multiple increase payment requests. This resolves race conditions that can occur when the billed-for activity is asynchronous to the protocol in which the micropayment protocol is embedded. In this case, it was previously impossible to know when the async activity could be resumed as it would otherwise race with the process of the server checking the payment signature and updating the balance. Most applications of micropayments will use a single protocol that has been extended with an embedding, and thus this is not an issue. However in some rare applications the payment process may run alongside the existing protocol rather than inside it. In this case, payment acks should be used for synchronization.		2013-11-01 15:31:57 +01:00
