Description: Binary data
if you want to look into the types thing, custom types that extend the base types have to use TypeDecorator again, like this:
class MyDecoratedType(types.TypeDecorator): impl = String def convert_bind_param(self, value, engine): return "BIND_IN"+ value def convert_result_value(self, value, engine): return value + "BIND_OUT" def copy(self): return MyDecoratedType() notice the "impl=String" class variable there.also, the Unicode and PickleType in the types module is already a TypeDecorator, so those can be extended directly.

I'm somewhat in a tight spot here, is there any specific change which I can get without all the rest that fixes the object issue? (i.e. I don't really have time to go chasing after trunk problems on general principle at the moment)Quoting Michael Bayer <[EMAIL PROTECTED]>:ah...are you using any custom types ? unfornately I had to shake up the interface for the TypeEngine object again. otherwise, yes id need more detail since all the unit tests pass.

I noticed that I have a huge objectleak all around (about 10k objects never get collected at every request) I wrote a testprogramm (atached) wich in a nutshell does while 1: select objectstore.clear() gc.collect() print len(gc.get_objects()) The numbers rolling down my screen never stabilize or decrease until the processes gets an out of memory exception. However when I take the objectstore.clear() out, the number is constant (this is not a solution for me, see first paragraph). I also noticed that this doesn't happen on windows, only on linux.
