ZC Buildout recipe to fake zope 2 packages as eggs.

Project Description

Zope 2 isn’t eggified yet, Zope 3 does. That can become a problem if you want to install some egg with depedencies related to Zope 3 eggs (such as zope.interface, zope.component, …)

This buildout recipe will simply add some fake egg link to zope libraries (installed inside zope/lib/python/zope/…) so that setuptools can see that the dependencies are already satisfied and it won’t fetch them anymore.

Detailed Documentation

Here is the most basic example:

>>> write('buildout.cfg',
... """
... [buildout]
... parts =
...     zope2
...     fakezope2eggs
...
... find-links =
...     http://dist.plone.org/
...
... [zope2]
... recipe = plone.recipe.zope2install
... url = http://www.zope.org/Products/Zope/2.9.7/Zope-2.9.7-final.tgz
...
... [fakezope2eggs]
... recipe = z3c.recipe.fakezope2eggs
... """)

Now if we run the buildout:

>>> print system(buildout)
Installing zope2.
running build_ext
creating zope.proxy
copying zope/proxy/proxy.h -> zope.proxy
building 'AccessControl.cAccessControl' extension
creating build
creating build/temp.linux-i686-2.4
creating build/temp.linux-i686-2.4/AccessControl
...

Now if we list all the developped egg we have:

>>> ls(sample_buildout, 'develop-eggs')
-  plone.recipe.zope2install.egg-link
-  z3c.recipe.fakezope2eggs.egg-link
-  zope.app.adapter.egg-info
-  zope.app.annotation.egg-info
-  zope.app.apidoc.egg-info
-  zope.app.applicationcontrol.egg-info
-  zope.app.appsetup.egg-info
-  zope.app.authentication.egg-info
-  zope.app.basicskin.egg-info
-  zope.app.broken.egg-info
-  zope.app.cache.egg-info
...

Let’s have a look at the content of one of them:

>>> cat(sample_buildout, 'develop-eggs', 'zope.app.adapter.egg-info')
Metadata-Version: 1.0
Name: zope.app.adapter
Version: 0.0

You might also want to add other fake eggs to your buildout, to do so use the additional-fake-eggs option, for example:

>>> write('buildout.cfg',
... """
... [buildout]
... parts =
...     zope2
...     fakezope2eggs
...
... find-links =
...     http://dist.plone.org/
...
... [zope2]
... recipe = plone.recipe.zope2install
... url = http://www.zope.org/Products/Zope/2.9.7/Zope-2.9.7-final.tgz
...
... [fakezope2eggs]
... recipe = z3c.recipe.fakezope2eggs
... additional-fake-eggs = ZODB3
... """)

>>> print system(buildout)
Uninstalling fakezope2eggs.
Updating zope2.
Installing fakezope2eggs.
<BLANKLINE>

Let’s check if the additionnal fake egg exists:

>>> cat(sample_buildout, 'develop-eggs', 'ZODB3.egg-info')
Metadata-Version: 1.0
Name: ZODB3
Version: 0.0
