gocept.patch_keyreferences

This package fixes the comparison between keyreferences of zope.keyreference in Python 3.

Reasoning

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.

Usage

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>
