- [feature] The Session will produce warnings
when unsupported methods are used inside the
"execute" portion of the flush. These are
the familiar methods add(), delete(), etc.
as well as collection and related-object
manipulations, as called within mapper-level
flush events
like after_insert(), after_update(), etc.
It's been prominently documented for a long
time that SQLAlchemy cannot guarantee
results when the Session is manipulated within
the execution of the flush plan,
however users are still doing it, so now
there's a warning. Maybe someday the Session
will be enhanced to support these operations
inside of the flush, but for now, results
can't be guaranteed.
