Okay. I looked at custom type and was about to implement one and I found
this:
http://docs.sqlalchemy.org/en/rel_0_8/core/types.html?highlight=json#marshal-json-strings
Do we have a plan to add JSON type?
I am looking at range.py and hstore.py to get an idea how one writes a data
type.

I am getting that same error (not the original one). For the moment i've
solved the problem in a different way, but it might pop up again. I'll keep
merge in mind (i've run into the is already attached to session before).
Thank you, Lars

I realised after I sent that script that I wasn't reproducing quite
the same situation. I should have loaded the person from the database
in sess2 as well, before trying to add the instance from sess1. In
other words, change the end of the test script to say:
sess2 = Session()

Race conditions can happen at any time, not just when the system is
under heavy load. You only need 2 requests to arrive at approximately
the same time to trigger a race condition.

like some connection state is being shared between requests.
I haven't used Tornado before and don't know much about it. Its main
feature is that it uses asynchronous IO, unlike most other python web
servers that use threads for

That might be it. We had a very similar bug: We stored ORM objects in the module
level and did not imediately realize that these
Hi,
Trying to advance on this issue i wrote an InstrumentedList which shall:
* hold only values sharing the same key as defined by a property on the
values
* change that property to the list value upon insertion
* set the property to whatever null value is defined when the value is
removed from
I don't honestly know, but if this were my project I would be trying
very hard to ensure that both (session.commit or session.rollback)
followed by session.close were being called at the end of every single
request.
Are you using any of Tornado's asynchronous capabilities (eg.
My version is 0.7.5 (thought i was on 8 already), i will look at updating!
The error sounds similar, I'll get back on this after i do (after some
research to find out if updating is a good idea right now)
Cheers, Lars

there's a trac ticket surrounding the job of adding the JSON type:
http://www.sqlalchemy.org/trac/ticket/2581
the closest type resembling this is the HSTORE type, so an approach here would
likely want to draw from some of the techniques of HSTORE.

Thanks. That's quite an interesting piece of code. There's a bit of magic
happening in this code and it's not quite compatible for my use case (use
of queries instead of tables, no ORM mapping), so allow me to ask some
questions. I've annotated the code, so perhaps you can correct any of my
