unnecessary dependency on setuptools

[Julian Taylor]

[Impact] networkx has setuptools in its requries.txt but not in its dependencies.
This causes pkg_resources.require tests to fail if python-setuptools is not installed
e.g. epigrass uses this and thus fails to start when python-setuptools is not installed.
See debian bug 639995
additionally in natty a numpy dependency is missing.

[Development Fix] fixed by removint setuptools from requires.txt

[Stable Fix] do the same

[Test Case]
have *no* python-setuptools installed
apt-get install python-pkg-resources
python -c "import pkg_resources as p; p.require('networkx')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 654, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 552, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: distribute

expected: successful require call

[Regression Potential]
low the setuptools dependency is unecessary, it is handled by python-pkg-resources (in recommends in networkx and depends on all users of this feature)

Hello Julian, or anyone else affected,

Accepted python-networkx into oneiric-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Hello Julian, or anyone else affected,

Accepted python-networkx into natty-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Is there really much point in fixing this in maverick now? It has lived most of its live with this bug, and will go EOL in two months.

[Julian Taylor (jtaylor)]

probably not, likely nobody will verify it for maverick anyway.

The fix works for me in oneiric.

This bug was fixed in the package python-networkx - 1.5-2ubuntu0.1

---------------
python-networkx (1.5-2ubuntu0.1) oneiric-proposed; urgency=low

  * debian/patches/50_no_setuptools_in_requires.txt
     - don't add setuptools to requires.txt;
       allows import with pkg_resources.require('networkx') like
       e.g. epigrass does (LP: #925744)

The fix for this bug has been awaiting testing feedback in the -proposed repository for lucid for more than 90 days. Please test this fix and update the bug appropriately with the results. In the event that the fix for this bug is still not verified 15 days from now, the package will be removed from the -proposed repository.

[Julian Taylor (jtaylor)]

verified the fix in a lucid chroot, no regressions reported in its very long stay in proposed or the newer releases where the fix is also present

[Brian Murray (brian-murray)]

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
