Egg extras not installed for recipes

Bug #85604 reported by Thomas Lotze on 2007-02-16
Affects Status Importance Assigned to Milestone

Bug Description

Automatic installation of eggs required by an egg extra doesn't seem to
work for a recipe used with zc.buildout as documented for eggs in general:

Suppose myrecipe has two entry points, the "fancy" one employing
yourrecipe. Now if I declare yourrecipe as an extra requirement only to be
installed if the "fancy" entry point is used to install any buildout part:



      entry_points={"zc.buildout": [
          "default =",
          "fancy = [bar_extra]", ]},
      extras_require={"bar_extra": ["yourrecipe"]}, ...

and use myrecipe I get a pkg_resources.DistributionNotFound error
concerning yourrecipe. It sort of works if I manually copy the yourrecipe
egg to the eggs directory beforehand, though.

Yup, extras are not always conserved by zc.buildout.
I see at least one place which it occurs, In zc.buildout.easy_install._constrain.Installer._constrain().

As i use personnaly minitage.recipe:egg in flavor of zc.recipe.egg, i work arounded that in this recipe.
You can see the result there (_constrain()):
