New issue 2501: [Pypy] Multiple Inheritance Bug: typeError: __init__() takes
exactly 1 argument (2 given)
https://bitbucket.org/pypy/pypy/issues/2501/pypy-multiple-inheritance-bug-typeerror
KSHMK:
I found an error while installing and running to use pwntools.
Pwntools inherits threading.local and stack implemented classes to implement a
stack for each thread.
However, when inheriting and executing __init__ "__init__() takes exactly 1
argument (2 given)". This error did not occur in Cpython.
```
#!python
import threading
class B(object):
def __init__(self, K):
self._current = K
self.__stack = []
def push(self):
print "push"
class A(threading.local, B):
pass
K = A({"asdf":"asdf"})
K.push()
print K._current
```
I have simplified the source of the error.
If you change the order of inheritance
```
#!python
import threading
class B(object):
def __init__(self, K):
self._current = K
self.__stack = []
def push(self):
print "push"
class A(B,threading.local):
pass
K = A({"asdf":"asdf"})
K.push()
print K._current
```
No Error. Why?
