Attempting to implement requests for block data revealed a problem with the previous connection logic. Block data is requested by sending a `getdata` message with hashes of the requested blocks; the peer responds with a sequence of `block` messages with the blocks themselves. However, this wasn't possible to handle with the previous connection logic, which could only convert a single Bitcoin message into a Response. Instead, we factor out the message handling logic into a Handler, which can statefully accumulate arbitrary data into a Response and signal completion. This is still pretty ugly but it does work. As a side effect, the HeartbeatNonceMismatch error is removed; because the Handler now tries to process messages until it comes to a Response, it just ignores mismatched nonces (and will eventually time out). The previous Mempool and Transaction requests were removed but could be re-added in a different form later. Also, the `Get` prefixes are removed from `Request` to tidy the name. |
