Prior to the scan-before-sync changes, the wallet was able to assume that the maximum scanned block height at the time of the spend was within a few blocks of the chain tip. However, under linear scanning after the spend-before-sync changes this invariant no longer holds, resulting in a situation where in linear sync conditions the wallet could attempt to create transactions with already-past expiry heights. This change separates the notion of "chain tip" from "max scanned height", relying upon the `scan_queue` table to maintain the wallet's view of the consensus chain height and using information from the `blocks` table only in situations where the latest and/or earliest scanned height is required. As part of this change, the `WalletRead` interface is also modified to disambiguate these concepts. |
