become an externally usable package but still remains within the main sqlalchemy parent package.
in this system, we use kind of an ugly hack to get the noseplugin imported outside of the
"sqlalchemy" package, while still making it available within sqlalchemy for usage by
third party libraries.
"cycles" among classes in highly interlinked patterns
would not produce a deterministic
result; thereby sometimes missing some nodes that
should be considered cycles and causing further
issues down the road. Note this bug is in 0.6
also; not backported at the moment.
[ticket:2282]
outside of "sqlalchemy" and under "test/".
Rationale:
- coverage plugin works without issue, without need for an awkward
additional package install
- command line for "nosetests" isn't polluted with SQLAlchemy options

in a separate collection. this collection also propagates during update()
- ClassManager now handles bases, subclasses collections.
- ClassManager looks at __bases__ instead of __mro__ for superclasses.
It's assumed ClassManagers are in an unbroken chain upwards through __mro__.
- trying to get a clear() that makes sense on cls.dispatch
- implemented propagate for attribute events, plus permutation-based test
- implemented propagate for mapper / instance events with rudimentary test
- some pool events tests are failing for some reason
the basic idea is to bring topological back down to the raw function,
then the whole UOW constructs itself as very fine grained elements with
full dependencies to each other. then a straight execute with a straight sort.
the hope is that the mechanism here would be vastly simpler. while
the presence of a large number of fine-grained records may be expensive
it still is potentially a lot easier to distill into C code, as the
uow's structure now consists of data.
