I'm using Google App Engine - with python 2.7 and web2py. My application
application suddenly stopped working with new deployment.
I deployed the application today (June14, 2013) and I get the error
"OverflowError: Python int too large to convert to C long" when web2py code
tries to store id() from DB entity into a int variable. As web2py DB
read/write is central to my application almost nothing works.
The last version of application deployed on June12, 2013 is working fine.
The same code deployed today does not work.
Is the problem related to the change to Google App Engine Release 1.8.1
where scattered auto id is the default?
Is Google team have solutions or support to us what need to change at
configuration level?
Call stack of failure (when web2py tries to write session object into
database):

I have performed below steps successfully:
- Deployment on sand box and testing
- Deployment on GAE
While accessing application getting below error after deployment, the
application was working fine previously.

*I came to know from the forums that we need to set “auto_id_policy:
legacy” in app.yaml file but exact syntax is not available. I have tried
own with few but did not get success on it*:
- auto_id_policy: legacy
- auto_id_policy= scattered
Kindly suggest what changes are required at configuration level, so that I
will be able to access the application.
Warm Regards,
Mukesh
