Package provides are resolved incorrectly with multiple apt sources

Description

version: 1.0.1-1~ppa2~hardy2 with Packages.py from svn [13349a073ff785fac7901038f980870bd508cbff] (SVN r6014)

We are running Lucid on the workstations where we found this bug. We have different aptsources for ubuntu, ubuntu-updates, ubuntu-security and ubuntu-backports. The machines in the ludid64 profile use all of them.

We are having trouble with packages that provide notification-daemon. The two common ones, notify-osd and xfce4-notifyd, conflict with each other. The ubuntu APTSource includes both of those packages and correctly returns them both(and two others) when get_provides() is run. ubuntu-updates has only xfce4-notifyd, so get_provides() only returns xfce4-notifyd.

Packages.complete() in source:/trunk/bcfg2/src/lib/Server/Plugins/Packages.py appears to be the method that takes care of this. It has a for loop that iterates through the different sources and runs resolve_requirement(). The for loop gets broken if it finds anything definitive in that source. Since it iterates through the sources in reverse order, it breaks out after finding xfce4-notifyd as the only provider in ubuntu-updates and never sees that the ubuntu source has other providers.

So, Packages.complete()needs to look at the union of the results from all relevant source when resolving requirements. I tried doing this in Packages.complete(), but I was unsuccessful.

Here is some output from bcfg2-info debug(with ipython ;)):

In [9739eeeb3d550e084a5de24062f440794c34a954] (SVN r6): s.get_provides(m, "notification-daemon")
