[Zope-dev] Zope 2: specifying Zope2 dependency

Hi!
Zope trunk (2.14) no longer ships with these Products:
Products.BTreeFolder2
Products.ExternalMethod
Products.MailHost
Products.MIMETools
Products.PythonScripts
Products.StandardCacheManagers
There are no separate Zope 2.12 compatible eggs for these Products
because they are part of the Zope2 2.12.X eggs.
Problem is: Several Products (e.g. CMF) exist that depend on these
Products and want to support Zope2 2.12, 2.13 and trunk. But AFAICS
there is no way to specify all dependencies correctly in setup.py. As a
workaround, CMF currently specifies the 'additional' Zope2 trunk
dependencies in buildout.cfg.
If there are no objections or better ideas, I'd like to add a
'zope212_compat' extra to Zope 2.12, 2.13 and trunk. For Zope 2.12 and
2.13 it would be empty, for trunk it would look like this:
extras_require={
'zope212_compat': [
'Products.BTreeFolder2',
'Products.ExternalMethod',
'Products.MailHost',
'Products.MIMETools',
'Products.PythonScripts',
'Products.StandardCacheManagers',
],
That would make it possible to specify the Zope2 dependency this way:
install_requires=[
'Zope2 [zope212_compat] >= 2.12.15',
]
If Products drop Zope 2.12 support, they can switch to this:
install_requires=[
'Zope2 >= 2.13.0',
'Products.MailHost', # required Products
]
Cheers,
Yuppie
