working with different requirements depending on python version
Hi All, While trying to debug another problem, I re-ran some Jenkins jobs for two of my packages, which promptly failed under Python 2.5: http://jenkins.simplistix.co.uk/job/testfixtures-buildout/ http://jenkins.simplistix.co.uk/job/checker-buildout/ Now, the issue here is that zope.interface 4.0 and above no longer supports Python 2.5: http://jenkins.simplistix.co.uk/job/checker-buildout/PYTHON=2.5,label=linux/... http://pypi.python.org/pypi/zope.interface/4.0.0 That's fine, but I'd like the above projects to continue 2.5 support for the time being. The simple solution would be to add a versions section to the buildout here: https://github.com/Simplistix/checker/blob/master/buildout.cfg ...and pin the versions in the tox.ini here: https://github.com/Simplistix/checker/blob/master/tox.ini ...however, that doesn't give the correct result. The version requirement is "use the latest version of all packages that work with the Python version under test" and the changes I've suggested would mean that on Python 2.6 and 2.7, the latest version of zope.interface wouldn't be used. What makes this even more "interesting" is that zope.interface isn't a direct requirement of either of these projects, it's a dependency of a dependency in both cases. How have other people solved this? Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk

How have other people solved this?
For repoze.sendmail, I did two fixups for Python 2.5: - - I changed 'install_requires' in setup.py based on sys.version_info https://github.com/repoze/repoze.sendmail/blob/master/setup.py - - I pinned the verstion in tox.ini: https://github.com/repoze/repoze.sendmail/blob/master/tox.ini Tres. - -- =================================================================== Tres Seaver +1 540-429-0999 tseaver@palladion.com Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk/vM2cACgkQ+gerLs4ltQ6wMACggHkNgiyVCWo83eEaJUu42p3m zz0An0xehOEKzMEiNQUnHP//1xYsaiJG =IE0o -----END PGP SIGNATURE-----

Thanks, that worked for me: https://github.com/Simplistix/testfixtures/commit/d56035510f7a63793a82b966b8... https://github.com/Simplistix/checker/commit/a5f8d089a3af7da1f1e8a5dc3182ea5... cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk
