No weak-reference error this morning, hooray. I'll be watching it for
a few days.
Could using a BoundMetaData in my model be contributing to the
problem? I have the following structure:
===
ctx = get_session_context()
# A custom function that creates a session_context like
# pylons.database, but reads more engine options from the
# config file.
engine = ctx.current.bind_to
meta = BoundMetaData(engine)
incidents = Table(..., meta, autoload=True)
ic = incident.columns
class Incident(object):
pass
assign_mapper(ctx, Incident, incidents)
def list_incidents(top_only):
q = Incident.query()
if top_only:
q = q.filter(Incident.c.is_top)
return q
===
So when list_incidents() is called it's in a different thread than
where all the variables were defined. The engine and metadata are
thread safe, right? Should I use a DynamicMetaData and temporarily
connect it to define the tables, and then connect it to None? Or
would that just me making things more complicated for no reason? As
far as I can tell there's only one engine shared throughout the
application anyway, so it shouldn't harm anything to use a
BoundMetaData.
Could we have session.engine be an alias for session.bind_to? Pretty
please? The only reason I leave a top-level 'engine' around is in
case I need it for something, because .bind_to is so non-obvious.
