python-formencode should depend on python-pkg-resources

[Adam Victor Brandizzi]

Binary package hint: python-formencode

When trying to use/import the Python formencode module from the package python-formencode 0.7.1-2 without the package python-pkg-resources installed, I've got the following exception:

>>> import formencode
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/formencode/__init__.py", line 1, in <module>
    from api import *
  File "/usr/lib/python2.5/site-packages/formencode/api.py", line 9, in <module>
    from pkg_resources import resource_filename
ImportError: No module named pkg_resources

So, I installed python-pkg-resources 0.6c8-0ubuntu2 and got no more errors. So, I bet python-formencode should have python-pkg-resources as a dependence.

Had this same problem today.
I installed python-setuptools which, in turn, depends on python-pkg-resources.

I agree with the OP that a dependency should be added.

Based on the mentioned versions I guess you are using Ubuntu hardy.
I've done a quick check on Ubuntu intrepid and couldn't reproduce it anymore so I guess it was fixed in intrepid.
Can you still reproduce this in Ubuntu intrepid?

I tried it on intrepid, and the error does not occur anymore. It seems the python-pkg-resources is installed by default in intrepid, but is not an dependency to python-formencode. Anyway, it worked fine.

We'd like to figure out what's causing this bug for you, but we haven't heard back from you in a while. Could you please provide the requested information? Thanks!

[Adam Victor Brandizzi (brandizzi+launchpad-net)]

Exatly what information?

This bug was caused because the package python-formencode did not depend upon the package python-pkg-resources in hardy, but python-pkg-resources is needed to the proper use of python-formencode. In intrepid, python-pkg-resources were installed by default for some reason, so python-formencode worked well - although the package python-formenconde still didn't list python-pkg-resources as a dependency. I believe it would be better to list python-pkg-resources as a dependency.

However, in karmic, the package python-formencode depends upon python-pkg-resources, as can be seen in its control file:

Depends: python (<< 2.7), python (>= 2.6), python-support (>= 0.7.1), python-dns, python-pkg-resources

From jaunty backwards, it does not occur, however.

I would say the bug was repaired in karmic - so, do I have to close the bug? Or should the bug be repaired in jaunty etc. to be closed? I am sorry, I am very confused, but I want to solve the problem...

This should be fixed on lucid already.
