That's the last of the RDBMS migration steps done! Yay! Note that the code currently has some unit testing issues: - Metakit needs some attention in a couple of areas - RDBMS backends are having trouble ordering their journal entries correctly. I'm going to be migrating them to use TIMESTAMP for the date column, but that's not necessarily going to fix things as mysql and postgresql both appear to have second granularity. Sqlite will ignore the data type as usual ;) Next up is the datatype-ification of the RDBMS backends. Part of that will involve the migration to numeric IDs, which will also be done in the *dbm backends (already done in metakit). The ID exposed *above* the hyperdb will be String, since so many things assume a string ID now.
