Hmm, very strange. I just did: $ uname -a Linux seabiscuit 2.6.22-14-generic #1 SMP \ Tue Dec 18 08:02:57 UTC 2007 i686 GNU/Linux $ python -V Python 2.5.1 $ cd ~/projects/Zope-CVS/Zope-trunk $ svn up ... $ python setup.py install --home=/home/tseaver/tmp/zpy25 ... (error on installing a script, but all libraries installed) $ cd ~/tmp/zpy25/ $ PYTHONPATH=lib/python/ python Python 2.5.1 (r251:54863, Oct 5 2007, 13:36:32) [GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from ExtensionClass import Base >>> from Acquisition import Implicit >>> class B(Base): ... color = 'red' ... >>> class A(Implicit): ... pass ... >>> b = B() >>> c = A() >>> c.color Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: color >>> b.c = c >>> b.c.color 'red' >>> b.c == c False which is what you reported. However, two wrappers constructed separately do compare equal: >>> a = A().__of__(b) >>> a.color 'red' >>> b.a = a >>> b.a == a True The Python 2.5 release notes don't talk about any changes to comparison slots for C extensions: I'm not sure what could have changed.
