Prev. we inserted data for tracking issued names into the `issuedNames` table during `sa.AddCertificate`. A more robust solution is to do this during `sa.AddPrecertificate` since this is when we've truly committed to having issued for the names. The new SA `WriteIssuedNamesPrecert` feature flag enables writing this table during `AddPrecertificate`. The legacy behaviour continues with the flag enabled or disabled but is updated to tolerate duplicate INSERT errors so that it is possible to deploy this change across multiple SA instances safely. Along the way I also updated `SA.AddPrecertificate` to perform its two `INSERT`s in a transaction using the `db.WithTransaction` wrapper. Resolves https://github.com/letsencrypt/boulder/issues/4565 |
