This package fixes the comparison between keyreferences of
zope.keyreference in Python 3.
In Python 2 zope.keyreference used to compare items via the __cmp__
method. This was facilitated by the C-implementation of the Zope security
packages, as it allowed the comparison without un-wrapping the security proxy
explicitly. Python 3 used rich comparison and this behaviour stopped working.
For further information see the following PR.
This package applies a monkey patch to make the fix usable although it is the wrong place to fix it in general.
To use this package include it in the zcml of you application:
<configure xmlns="http://namespaces.zope.org/zope">
<include package="gocept.patch_keyreferences" />
</configure>
