The manager class of the multiprocessing module doesnt implement __next__ or __iter__ on its dictionary method and relies on using __getitem__. This results in an unexpected functionality of an object that is supposed to act like a dict, and instead of looping over the dictionary keys it loops over its values. The user needs to call dict() on this object in order to loop over it correctly, which is not that obvious. The problem originates from there https://github.com/python/cpython/blob/master/Lib/multiprocessing/managers.py#L1136 Poc link: https://hastebin.com/codoqihowi.py |

DictProxy needs to provide the __iter__() method. And perhaps methods keys(), values() and items() need to be reworked in Python 3. has_key() is unneeded in Python 3. It is worth to test also other special and new in Python 3 methods. |
