That sounds even nicer, and since I'm just starting out with no legacy
code I've been meaning to try dropping 0.8 in even before it is final. It
sounds like I could just do something like
event.listen(MyDeclarativeSubclass, load, myStamperFunc).
I popped in 0.8b2 and tried something

there's no class level GC cycle when dealing with the Session object, no, this
bug is local to the ad-hoc subclass mechanism of sessionmaker().

Hi everyone,
A few months ago I asked about MySQL 5.5 support. Ubuntu's package manager had
upgraded me to MySQL 5.5, but SQLAlchemy's docs state the following:
SQLAlchemy supports 6 major MySQL versions: 3.23, 4.0, 4.1, 5.0, 5.1 and 6.0,
with capabilities increasing with more modern servers.

I created a runnable .py while that mimicked the tables and models as
closely as possible using a SQLite in-memory engine, but aggravatingly, I
can't reproduce the problem with it.
I discovered that the problem goes away when you set echo=True
in engine_from_config, the problem goes away, so my
if echo=True is affecting it that usually refers to an issue that is triggered
by hash ordering, which is non-deterministic. I've observed that printing to
standard out often has some correlation with hash ordering going in one
direction or the other.
Seems like you've definitely hit some

yeah you don't want to have unmapped instances of mapped classes lying around.
Why? They're just objects.
It's really handy having domain objects that can

I'm trying to figure out the correct way to use these array comparisons
features specific to postgres, e.g.:
select * from foo where 1 = any(bar);
So I tried this:
from sqlalchemy.sql.expression import func
session.query(foo).filter(1 == func.any(foo.c.bar))
But that didn't work, as I got this
