2006-05-25T14:20:23+00:00

fixed a _get_criterion mismatch, cleaned up types + updated types doc

2006-05-05T17:23:00+00:00

added from_obj option to select()

mapper will verify class inheritance scheme; also will not re-init inherited property, as the improved attribute system seems to handle inheritance OK and allows the property to keep its correct initialization on the parent

2006-04-18T18:24:07+00:00

exceptions import in query

a little spring cleaning for the util package, etc

2006-04-07T00:11:13+00:00

split up Session into Session/LegacySession, added some new constructor args

2006-04-06T23:46:02+00:00

created AbstractEngine class which provides base for SQLEngine and will also
provide base for ConnectionProxy, so SQL binding can be to an engine or specific
connection resource
ClauseElements get using() method which can take AbstractEngines for execution
made more separation between SchemaItems and bound engine

mapper's querying facilities migrated to new query.Query() object, which can receive session-specific context via the mapper.using() statement. reuslting object instances will be bound to this session, but query execution still handled by the SQLEngines implicit in the mapper's Table objects.

session now propigates to the unitofwork UOWTransaction object, as well as mapper's save_obj/delete_obj via the UOWTransaction it receives. UOWTransaction explicitly calls the Session for the engine corresponding to each Mapper in the flush operation, although the Session does not yet affect the choice of engines used, and mapper save/delete is still using the Table's implicit SQLEngine.
changed internal unitofwork commit() method to be called flush().
removed all references to 'engine' from mapper module, including adding insert/update specific SQLEngine methods such as last_inserted_ids, last_inserted_params, etc. to the returned ResultProxy so that Mapper need not know which SQLEngine was used for the execute.
changes to unit tests, SelectResults to support the new Query object.
