python-nose is broken with python 2.6.3-dev

[Darren Dale]

Binary package hint: python-nose

python-nose is broken in Karmic alpha 2:

$ nosetests
Traceback (most recent call last):
  File "/usr/bin/nosetests", line 8, in <module>
    load_entry_point('nose==0.10.4', 'console_scripts', 'nosetests')()

After a manual update to nose version 0.11.0 it is still fully broken the exact same way.
There is something broken here but I'm not sure what the root cause is...

[Xavier Gnata (xavier-gnata-gmail)]

It works fine with python2.5 but not with Python 2.6.2+ (release26-maint, Jun 19 2009, 15:16:33)

[Darren Dale (dsdale24)]

Perhaps something to do with where the package is installed? Maybe pkg_resources doesn't know how to handle all the unconventional package locations created by debian's python policy.

This looks similar to https://bugs.launchpad.net/ubuntu/+source/nose/+bug/337585

I can confirm that the problem still exists.

[Xavier Gnata (xavier-gnata-gmail)]

The problem is still there and is quite puzzling:

[Andrew Straw (astraw)]

It seems a difference between -0ubuntu1 and -0ubuntu2 (jaunty and karmic alpha 2) is this. It looks very relevant.

NB that the change mentioned above is an upstream one.

The problem is in essence that an upstream change to unittest reveals a bug in how nose overrides TestProgram.runTests.

I shall file a bug upstream.

<- as i see it this bug is fixed since over a month in upstream, would make me happy if the maintainer could make a new python-release package that fix fix this problem.

[spiderbit (stefan-canta-game)]

sorry, assigned to wrong person, ubuntu-core-dev is "the" maintainer

[fherdom (fhernandeze)]

no problem, if i can help you... i work all day with python

Where is the fix??
http://bugs.python.org/issue6177 does not provide the fix. It is the commit which *breaks* python-nose.

nosetests returns

It is still broken.

[spiderbit (stefan-canta-game)]

Hmm ok I think you are right.

I did not test it. But i think you are right. Sorry i read next time more accuratly. I thought i see a bug that describes the bug, and a patch. But it seems to be another problem which fix broke this.

[Xavier Gnata (xavier-gnata-gmail)]

Indeed :)
Nose is still fully broken in karmic :(

File "/usr/lib/pymodules/python2.6/nose/core.py", line 192, in runTests
    result = self.testRunner.run(self.test)

[JP (jpellerin+nose)]

This is the upstream bug (in python core, not nose): http://bugs.python.org/issue6418

According to Michael Foord, it's fixed in the 2.6 branch and trunk. Maybe karmic isn't updated yet? I have no idea how or when that process happens.

[Launchpad Janitor (janitor)]

This bug was fixed in the package python2.6 - 2.6.2-0ubuntu3

---------------
python2.6 (2.6.2-0ubuntu3) karmic; urgency=low

  * Add debian/patches/issue6418.dpatch taken from the 2.6 release branch
    to fix problems with other test runners. (LP: #389942)
