Actually it already fails with 3.1 (I tried "hg up v3.1")
Then I played with "hg bisect", and unsurprisingly it answered:
Traceback (most recent call last):
File "", line 1, in
AttributeError: '_io.StringIO' object has no attribute '__dict__'
Changeset
Antoine Pitrou added the comment:
I'm not sure why that is. Note that you can still set and get arbitrary
attributes, so there must be a dict somewhere, but it isn't exposed. Also,
there wasn't any significant change in StringIO in the 3.1 line.
Benjamin, do you have any idea?
>>> s = io.Stri
New submission from Eric Promislow :
I see that going from Python 3.1.1 to 3.1.2
instances of io.StringIO no longer have a __dict__ field.
Why? Is this to make them unpicklable?
