Compatibility patches.
Please keep the following principles in mind:
* Keep imports local, so that importing this module does not cause too many
side effects by itself.
* Try to make patches idempotent, calling them multiple times should not do
harm. If that is not possible, ensure that the second call explodes.
def kombu_1_5_1_python_2_7_11():
Kombu 1.5.1 relies on a private method which got removed in Python 2.7.11.
This patch adds the symbol to the module :mod:`uuid` and assigns the value
``None`` to it. This causes kombu to fall back to the public API of
This patch can most probably be removed once celery and kombu are updated
to more recent versions.
import uuid
if not hasattr(uuid, '_uuid_generate_random'):
uuid._uuid_generate_random = None
def inspect_getargspec():
Pyramid and Pylons rely on inspect.getargspec to lookup the signature of
view functions. This is not compatible with cython, therefore we replace
getargspec with a custom version.
Code is inspired by the inspect module from Python-3.4
import inspect
def _isCython(func):
Private helper that checks if a function is a cython function.
return func.__class__.__name__ == 'cython_function_or_method'
def unwrap(func):
Get the object wrapped by *func*.
Follows the chain of :attr:`__wrapped__` attributes returning the last
object in the chain.
*stop* is an optional callback accepting an object in the wrapper chain
as its sole argument that allows the unwrapping to be terminated early
if the callback returns a true value. If the callback never returns a
true value, the last object in the chain is returned as usual. For
example, :func:`signature` uses this to stop unwrapping if any object
in the chain has a ``__signature__`` attribute defined.
:exc:`ValueError` is raised if a cycle is encountered.
f = func # remember the original func for error reporting
memo = {id(f)} # Memoise by id to tolerate non-hashable objects
while hasattr(func, '__wrapped__'):
func = func.__wrapped__
id_func = id(func)
if id_func in memo:
raise ValueError('wrapper loop when unwrapping {!r}'.format(f))
return func
def custom_getargspec(func):
Get the names and default values of a function's arguments.
A tuple of four things is returned: (args, varargs, varkw, defaults).
'args' is a list of the argument names (it may contain nested lists).
'varargs' and 'varkw' are the names of the * and ** arguments or None.
'defaults' is an n-tuple of the default values of the last n arguments.
func = unwrap(func)
if inspect.ismethod(func):
func = func.im_func
if not inspect.isfunction(func):
if not _isCython(func):
raise TypeError('{!r} is not a Python or Cython function'
args, varargs, varkw = inspect.getargs(func.func_code)
return inspect.ArgSpec(args, varargs, varkw, func.func_defaults)
inspect.getargspec = custom_getargspec
