Package: zope2.12
Version: 2.12.26-1
Severity: important

Dear Maintainer,

Debian testings python2.6 support has decayed to the point where
Zope2.12 can nolonger run.

After recent updates on my Debian testing system, I found Zope would
not start. Running the start command manually revealed a missing import;


$ sudo dzhandle -z 2.12 zopectl minkirri start
Traceback (most recent call last):
  File "/usr/lib/zope2.12/bin/python", line 78, in <module>
    execfile(__file__)
  File "/usr/lib/zope2.12/bin/zopectl", line 3, in <module>
    import Zope2.Startup.zopectl
  File "/usr/lib/zope2.12/lib/python/Zope2-2.12.26.egg/Zope2/Startup/zopectl.py", line 44, in <module>
    import pkg_resources
ImportError: No module named pkg_resources

This package is installed by python-pkg-resources into pyshared and
only creates a symlink to it for python2.7;

$ dpkg -S pkg_resources.py
python-pkg-resources: /usr/share/pyshared/pkg_resources.py
python-pkg-resources: /usr/lib/python2.7/dist-packages/pkg_resources.py

Note that I have python-pkg-resources version 0.6.37-1 installed.

After manually creating a python2.6 link for it, zope would
successfully start, but the logs showed that at least one important
import (docutils) fails, breaking things like zwiki;

2013-06-28T13:31:18 ERROR Application Could not import Products.ZReST
Traceback (most recent call last):
  File "/usr/lib/zope2.12/lib/python/Zope2-2.12.26.egg/OFS/Application.py", line 596, in import_product
    product=__import__(pname, global_dict, global_dict, silly)
  File "/usr/lib/zope2.12/lib/python/Zope2-2.12.26.egg/Products/ZReST/__init__.py", line 7, in <module>

  File "/usr/lib/zope2.12/lib/python/Zope2-2.12.26.egg/Products/ZReST/ZReST.py", line 11, in <module>
    import docutils.core
ImportError: No module named docutils.core

At this point I gave up trying to make it work with python2.6, since
there are way too many manual symlinks I'd need to create. Instead, I
decided to edit dzhandle to use python2.7 instead.

To do this I edited /user/bin/dzhandle, changing pyver in
zope_packages for zope2.12, and edited /usr/lib/zope2.12/bin/python
changing the #! line to python2.7. After doing this zope seemed to
start OK, but dies at the first http request without logging anything.

It may be that this bug should be re-assigned to python-pkg-resources
and python-docutils asking why they have stopped supporting python2.6,
but I suspect the answer will be update to python2.7, or drop this
package from Debian testing.

This leaves me with an unusable zope2.12 instance. What are my options
for upgrading my content that will run on a Debian testing system?
