pkgcore does not tolerate -scm suffix in ebuilds

[anonymous]

  File "/usr/lib/python2.5/site-packages/pkgcore/ebuild/ebuild_built.py", line 155, in new_package
    inst = self._cached_instances[args] = self.child_class(self, *args)
  File "/usr/lib/python2.5/site-packages/pkgcore/package/metadata.py", line 47, in __init__
    original_kls.__init__(self, *a, **kwds)
TypeError: cpv accepts either 1 arg (cpvstr), or 3 (category, package, version); all must be strings: got ('sys-apps', 'paludis-scm', None)

I would suggest that pkgcore give some nice warnings instead of errors and a nicely formatted error msg instead of a backtrace :)

Hey now, the exception is concise enough ;)

Will beautify it for next release. Regarding "give warnings instead of errors", PM's advocating that are by and large doing a pretty dangerous disservice to their users- here be why.

1) install kde-scm w/ -scm aware manager. shiny, you're outside eapi1 atm, but you've got your kde 2) you try using a different manager that doesn't know of -scm, just ignores the entries. along the way of dep resolution, it goes to install kde. since the manager can't "see" kde-scm is there, it stomps the install instead of properly upgrading it. 3) chaos ensues.

How much progress has been made wrt this?

I took care of this one a while back actually; additionally, there is a feature (ignore-paludis-versioning) to ignore invalid ebuilds like that.
