The first step is still to get DNF “working” with RPM5 using python2: there are 
multiple ports involved.

If you expose you git repositories, I can try to help.

I have already forked all the relevant repositories and done some of the 
necessary porting
back in August:

https://github.com/orgs/rpm5/dashboard

Meanwhile, rpm-python3 is just a small piece of a much larger puzzle.

Until DNF is ported to use rpm5 (with test cases and coverage), rpm—python3 is
a NICETOHAVE answer in search of a question.

Functioning DNF with RPM5 is MUST’VE.

Meanwhile — in order to finish rpm-python3 — there needs to be some
usage case.

On a random Fedora 24 installation, I see the following packages using
rpm-python3:

$ rpm -q --whatrequires rpm-python3
rpmconf-1.0.16-2.fc24.noarch
python3-dnf-1.1.10-1.fc24.noarch

mock-1.2.21-1.fc24.noarch

Which of those packages is of interest to you?

Offhand, I don’t see any important applications there that MUST have
rpm-python3.


The usage case is that Yocto Project is replacing smartpm with dnf.

Dnf can (still) be configured to use Python 2, but we strongly prefer to 
use Python 3 from the beginning.

rpm-python was converted to python3 (and generally blue-printed against
the rpm.org python module) at least 1 year ago afaik.

Meanwhile, no one has tried to compile/use rpm-python with python3. There’s 
surely some bugs.
