Fixed bug in ORM-level event registration where the "raw" or

2013-07-19T03:19:04+00:00

"propagate" flags could potentially be mis-configured in some
"unmapped base class" configurations.  Also in 0.8.3.

- A clear error message is emitted if an event handler

attempts to emit SQL on a Session within the after_commit()
handler, where there is not a viable transaction in progress.
[ticket:2662]
- rework how SessionTransaction maintains state, using symbols
instead.
- add lots of notes and cross-linking for session events.
- add a link to :func:`.select()` within :meth:`.FromClause.select`.

iterating through all mappers in memory when a new event is tacked
onto an unmapped superclass, also removes the strong ref that was
breaking some GC teardown tests

after subclasses are already mapped

- lets default propagate to True here since it was essentially always

    mapped classes allows that unmapped classes
    can be specified for instance- and mapper-events.
    The established events will be automatically
    set up on subclasses of that class when the
    propagate=True flag is passed, and the
    events will be set up for that class itself
    if and when it is ultimately mapped.

  - [bug] The instrumentation events class_instrument(),
    class_uninstrument(), and attribute_instrument()
    will now fire off only for descendant classes
    of the class assigned to listen().  Previously,
    an event listener would be assigned to listen
    for all classes in all cases regardless of the
    "target" argument passed.  [ticket:2590]
