This will prevent + ``StackContexts`` from leaking from one request to another. + +* If you want to write something like an exception handler that will + persist across asynchronous calls, create a new `StackContext` (or + `ExceptionStackContext`), and make your asynchronous calls in a ``with`` + block that references your `StackContext`. +""" + +from __future__ import absolute_import, division, print_function, with_statement + +import sys +import threading + +from .util import raise_exc_info + + +class StackContextInconsistentError(Exception): + pass + + +class _State(threading.local): + def __init__(self): + self.contexts = (tuple(), None) +_state = _State() + + +class StackContext(object): + """Establishes the given context as a StackContext that will be transferred. + + Note that the parameter is a callable that returns a context + manager, not the context itself.
