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/15/console
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?
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
