Description Lukas Slebodnik 2015-02-11 14:28:12 UTC

Description of problem:
python3-dnf requires dnf which requires python2. Therefore python3-dnf cannot be used without python2. As a result if this I cannot prepare minimal container image without python2.

[root@host ~]# rpm -q --requires python3-dnf | grep "python\|dnf"
/usr/bin/python3
dnf = 0.6.3-2.fc21
python(abi) = 3.4
python3-hawkey >= 0.5.2
python3-iniparse
python3-libcomps >= 0.1.6
python3-librepo >= 1.7.5
python3-pygpgme
rpm-python3 >= 4.12.0

[root@host ~]# rpm -q --requires dnf | grep "python\|dnf"
/usr/bin/python
config(dnf) = 0.6.3-2.fc21
python(abi) = 2.7
python-hawkey >= 0.5.2
python-iniparse
python-libcomps >= 0.1.6
python-librepo >= 1.7.5
rpm-python >= 4.12.0


Version-Release number of selected component (if applicable):

[root@host ~]# rpm -q python3-dnf dnf
python3-dnf-0.6.3-2.fc21.noarch
dnf-0.6.3-2.fc21.noarch

How reproducible:
Deterministic

Comment 1 Martin Kosek 2015-02-11 14:49:41 UTC

CCing Slavek, he should be aware.

Comment 2 Bohuslav "Slavek" Kabrda 2015-02-11 15:03:15 UTC

AFAIK dnf should be switched to python3-dnf in F22 and rawhide, so this shouldn't be a problem when the switch happens... But someone from dnf maintainers should confirm.

Comment 3 Lukas Slebodnik 2015-02-11 15:16:26 UTC

The most problematic part is that configuration file is owned by package "dnf"
The packaging need to be changed anyway because python3-dnf does not work without configuration file.

[root@host ~]# rpm -ql dnf | grep "/etc"
/etc/bash_completion.d/dnf-completion.bash
/etc/dnf
/etc/dnf/dnf.conf
/etc/dnf/plugins
/etc/dnf/protected.d/dnf.conf
/etc/libreport/events.d/collect_dnf.conf
/etc/logrotate.d/dnf

[root@host ~]# rpm -ql python3-dnf | grep "/etc"
[root@host ~]# echo $?
1

Comment 4 Honza Silhan 2015-03-05 17:24:33 UTC

The packaging of DNF was changed, the packages should be independent in f21, f22, f23 and epel7 for python API usage. This PR [1] moves conf inside each subpackage so it can be run from cmdline too.
