Hi.
I don't know if this is a bug of Cookie module or of
pickle.

When I dump a Cookie instance with protocol = 2, the
data is 'corrupted'.
With protocol = 1 there are no problems.

Here is an example:

>>> s = 'Set-Cookie: key=value; path=/; expires=Fri,
21-May-2004 10:40:51 GMT'
>>> c = Cookie.BaseCookie(s)
>>> print c
Set-Cookie: key=value; expires=Fri,; Path=/;

>>> buf = pickle.dumps(c, protocol = 2)
>>> print pickle.loads(buf)
Set-Cookie: key=Set-Cookie: key=value; expires=Fri,;
Path=/;;

>>> buf = pickle.dumps(c, protocol = 1)
>>> print pickle.loads(buf)
Set-Cookie: key=value; expires=Fri,; Path=/;



Thanks and regards  Manlio Perillo

Okay, I've looked at the output from protocols 0, 1 and 2
from pickletools.py, and after nearly two hours of looking
into this, I think the problem lies with the fact that both
Morsel and BaseCookie derive from dict and override __setitem__.

I think that this stems from BUILD using __dict__ directly,
but lack the internal knowledge of pickle to investigate
further.

#826897 appears to be a dupe of this.

__setitem__ is called for the items in the dict *before* the
instance variables are set.
