Olaoluwa Osuntokun bf6001074c chainntnfs: fix spend notification registration race condition ... In this commit, we fix a race condition related to the way we attempt to query to see if an outpoint has already been spent by the time it’s registered within the ChainNotifier. If the transaction creating the outpoint hasn’t made it into the mempool by the time we execute the GetTxOut call, then we’ll attempt to query for the transaction itself. In this case, if we query for the transaction, then the block hash field will be empty as it hasn’t yet made it into a block. Under the previous logic, we’d then attempt to force a rescan. This is an issue as the forced rescan will fail since it’ll try to fetch the block hash of all zeroes. In this commit, we fix this issue by only entering this “fallback to rescan” logic iff, the transaction has actually been mined.		2018-01-28 14:48:56 -08:00
