Hi,
Many web frameworks and ORM tools have the need to propagate data
depending on some or other context within which a request is dealt with.
Passing it all via parameters to every nook of your code is cumbersome.
A lot of the frameworks use a thread local context to solve this
problem. I'm assuming these are based on threading.local.
(See, for example:
http://www.sqlalchemy.org/docs/05/session.html#unitofwork_contextual )
Such usage assumes that one request is served per thread.
This is not necessarily the case. (Twisted would perhaps be an example,
but I have not checked how the twisted people deal with the issue.)
The natural solution with WSGI is to store objects in the environ
dictionary.
In fact in my web applications I always pass the environ dictionary
explicitly to every functions.
