New submission from Tim Graham:
I noticed some failing Django tests on Python 3.2.6 the other day. The
regression is caused by this change:
https://github.com/python/cpython/commit/572d9c59a1441c6f8ffb9308824c804856020e31
Behavior before that commit (and on other version of Python even after that
commit):
>>> from http.cookies import SimpleCookie
>>> SimpleCookie("Set-Cookie: foo=bar; Path=/")
<SimpleCookie: foo='bar'>
New broken behavior on Python 3.2.6:
>>> from http.cookies import SimpleCookie
>>> SimpleCookie("Set-Cookie: foo=bar; Path=/")
<SimpleCookie: >
Python 3.2.6 no longer accepts the "Set-Cookie: " prefix to BaseCookie.load:
>>> SimpleCookie("Set-Cookie: foo=bar; Path=/")
<SimpleCookie: >
>>> SimpleCookie("foo=bar; Path=/")
<SimpleCookie: foo='bar'>
This issue doesn't affect 2.7, 3.3, or 3.4 because of
https://github.com/python/cpython/commit/b92e104dc57c37ddf22ada1c6e5380e09268ee93
(this commit wasn't backported to 3.2 because that branch is in
security-fix-only mode).
I asked Berker about this and he suggested to create this issue and said, "If
Georg is OK to backout the commit I can write a patch with additional test
cases and commit it."
He also confirmed the regression as follows:
I've tested your example on Python 2.7.8, 3.2.6, 3.3.6, 3.4.2, 3.5.0 (all
unreleased development versions - they will be X.Y.Z+1) and looks like it's a
regression.
My test script is:
try:
from http.cookies import SimpleCookie
except ImportError:
from Cookie import SimpleCookie
c = SimpleCookie("Set-Cookie: foo=bar; Path=/")
print(c)
Here are the results:
Python 2.7.8:
Set-Cookie: foo=bar; Path=/
Python 3.5.0:
Set-Cookie: foo=bar; Path=/
Python 3.4.2:
Set-Cookie: foo=bar; Path=/
Python 3.3.6:
Set-Cookie: foo=bar; Path=/
