Bug 1049226

Reproduced.

Not a bug in latest_per_arch, but a feature of libsolv itself: it by default does not add available packages of incompatible architectures (I assume this was run on x86_64) to the whatprovides structures. The querying then can fail as a result.

Dan, you can use hawkey directly and specify a different architecture when creating the Sack:

sack = hawkey.Sack(arch=ppc64)

Michael, is there an option in libsolv to consider all packages in cases like this?

I tried following hack and the test passed:
import dnf.package
import dnf.sack
from dnf.sack import Sack

def build_sack(base):
    cachedir = base.conf.cachedir
    # create the dir ourselves so we have the permissions under control:
    dnf.util.ensure_dir(cachedir)
    return Sack(pkgcls=dnf.package.Package, pkginitval=base,
                cachedir=cachedir,
                rootdir=base.conf.installroot, arch="ppc64") # added ppc64 arch

dnf.sack.build_sack = build_sack

I think following scenarios should be supported:
1) default system arch
sack = hawkey.Sack()

2) user defined arch
sack = hawkey.Sack(arch="ppc64")

3) all arches in repo (consider repoquery and similar tools)
sack = hawkey.Sack(arch="ALL")

1) and 2) -- packages of incompatible arches should not be available in the sack

No, the whatprovides hash intentionally only contains "installable" packages.

I don't see why filter_latest really needs to use it, though. Just change the code to push all package ids in the "res" map onto the samename queue, then sort the queue by package name.

(that last comment was an answer to Ales question, of course)

If you want to implement arch="ALL", just don't call pool_setarch (or call it with a NULL arch.

Maybe do something like: http://paste.fedoraproject.org/66471/
