That's gadfly done, mostly. Things left: - Class.filter (I'm a wuss ;) - schema changes adding new non-multilink properties are not implemented. gadfly doesn't have an ALTER TABLE command, making that quite difficult :) I had to mangle two unit tests to get this all working: - gadfly also can't handle two handles open on the one database, so testIDGeneration doesn't try that. - testNewProperty is disabled as per the second comment above. I noticed test_pack was incorrect, and the *dbm tests fail there now. Looking into it...
