Last summer I saw bug #127321 an thought, this can be done by me (partly at least).
After some (successful) prototypic implementation, most of the time where spent into smooth integration in the existing
project:
- adding a solution for migrating from SQLite to MySQL and vice versa
- add possibility to start an own database server
- and bug fixing...
Because only a few persons trying out this work (which resides atm. in a dedicated branch), the most bugs are possible undiscovered.
