- Drop initialization of all columns on table create in favor of checking each column individually. This is slower but guarantees that each column is only defined once in the code. Columns are only created once so having clean code outweighs performance.
- Write more datasource integration tests
- Rename autoPurging to isPurging: we should always register if a purge task is in progress (regardless if autopurge or not) and deny any new requests
- Reduce the same logic being coded multiple times by calling through the methods
- DataSource: remove purgeBanned in favor of purgeRecords, both do exactly the same thing
- Change ForceFlatToSqlite converter to use a generic datasource destination (i.e. can be used for Flat2MySQL later)
- Add tests, including for FlatFile
- Check that user is not present in destination datasource before adding
- Persist last location from flatfile as well
