[web2py] Re: Help with App memory usage

2016-10-14 Thread Niphlod 
try using psycopg2 on the prod env too. pg8000 (especially the one shipped 
with web2py in the latest stable, which was quite old) can exhibit memory 
leaks (or, for better saying, a premature optimization resulted in an 
"evil" usage of the memory for the way web2py uses pg8000).

Which driver are you using for postgres? Are you using cache in models?
Try to figure out if there are controllers using more memory than others.

That's a lot of code to review. You're probably going to have to do some 
digging and narrow it down for us. I did see one problem, though:

class IS_BARCODE_AVAILABLE(object): 
T = current.T

You can't use current in a class attribute (for the same reason it can't be 
used at the top level of a module -- it's value will be fixed at the first 
import, though it is a thread-local object that should change with every 
request).
