Bugzilla Bug 201045

Recently, emerge --depclean decided to unmerge sys-auth/policykit and
gnome-extra/policykit-gnome.  However, even though policykit-gnome DEPENDs on
policykit, policykit was unmerged first.

This causes issues with the binary dependency hack:

 * pre_pkg_prerm: bindepcheck.sh ...
 * Binary object libpolkit.so.2.0.0 will be removed, checking for dependencies:
 *      (none)
 * Binary object libpolkit.so.2 will be removed, checking for dependencies:
 *      gnome-extra/policykit-gnome-0.7_pre20071106
 * Binary object libpolkit.so will be removed, checking for dependencies:
 *      (none)
 * Binary object libpolkit-dbus.so.2.0.0 will be removed, checking for
dependencies:
 *      (none)
 * Binary object libpolkit-dbus.so.2 will be removed, checking for
dependencies:
 *      gnome-extra/policykit-gnome-0.7_pre20071106
 * Binary object libpolkit-dbus.so will be removed, checking for dependencies:
 *      (none)
 * Binary object libpolkit-grant.so.2.0.0 will be removed, checking for
dependencies:
 *      (none)
 * Binary object libpolkit-grant.so.2 will be removed, checking for
dependencies:
 *      gnome-extra/policykit-gnome-0.7_pre20071106
 * Binary object libpolkit-grant.so will be removed, checking for dependencies:
 *      (none)
 * Removing policykit-0.7_pre20071101 will break binary dependencies of the
above listed
 * packages.  Remerging the above packages may prevent this.

emerge --unmerge gnome-extra/policykit-gnome sys-auth/policykit has the same
issue; in both cases the unmerge list appears to be coming from arbitrary-order
traversal of a dict (unlike merging, where dependencies are respected).

This has a pretty trivial workaround (emerge --unmerge
gnome-extra/policykit-gnome && emerge --unmerge sys-auth/policykit), but it'd
still be useful, esp. as depclean already has a full dependency tree
calculated.  Perhaps it'd be enough for emerge --unmerge to respect the
command-line order?

Technically, it's the RDEPEND and PDEPEND (runtime deps) that should matter
here. The DEPEND is supposed to be completely optional at this stage.

The digraph that depclean currently creates does not include any information
about dependency priority. It needs to be more like the one that depgraph
creates for installation actions, which places DepPriority objects in the
digraph.

This is fixed in 2.2_pre3.

This is supposed to be fixed in portage-2.2_pre5 or earlier.
