New submission from qwjqwj <q...@papayamobile.com>:
It has a typo error in cStringIO.StringIO's class name "StringO":
>>> import cStringIO
>>> a=cStringIO.StringIO()
>>> a
<cStringIO.StringO object at 0xb7eef240>
>>> a.__class__.__name__
'StringO'
So we can't unpickle the object correctly with Python 2.5.4:
>>> import pickle
>>> pickle.loads(pickle.dumps(a))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.5/pickle.py", line 1366, in dumps
Pickler(file, protocol).dump(obj)
File "/usr/local/lib/python2.5/pickle.py", line 224, in dump
self.save(obj)
File "/usr/local/lib/python2.5/pickle.py", line 306, in save
rv = reduce(self.proto)
File "/usr/local/lib/python2.5/copy_reg.py", line 69, in _reduce_ex
raise TypeError, "can't pickle %s objects" % base.__name__
TypeError: can't pickle StringO objects
When using multiprocess library, it also use the pickling and unpickling
of cStringIO.StringIO object
