Previously, the upgrade was organized as two passes -- an upgrade pass, and a separate cleanup pass -- so the database was always in a valid state. This change substantially simplifies this code by performing the upgrade in a transaction and combining both passes in to one. This 1) eliminates a lot of duplicate code between the passes, 2) speeds up the upgrade process, 3) makes progress reporting more accurate, 4) eliminates the potential for stale data if the upgrade is interrupted during the cleanup pass, and 5) makes it easier to reason about the safety of the upgrade code. |
