Dandified Yum

Dandified Yum (DNF) is the next upcoming major version of Yum. It does package management using RPM, libsolv and hawkey libraries. For metadata handling and package downloads it utilizes librepo. To process and effectively handle the comps data it uses libcomps.

Installing

DNF and all its dependencies are available in Fedora 18 and later, including the rawhide Fedora.

Optionally you can use repositories with DNF nightly builds for last 2 stable Fedora versions available at copr://rpmsoftwaremanagement/dnf-nightly. You can enable the repository e.g. using:

dnf copr enable rpmsoftwaremanagement/dnf-nightly

Then install DNF typing:

sudo yum install dnf

In other RPM-based distributions you need to build all the components from their sources.

Building from source

From the DNF git checkout directory:

mkdir build;
pushd build;
cmake .. && make;
popd;

Then to run DNF:

PYTHONPATH=`readlink -f .` bin/dnf <arguments>

Building and installing rpm

From the DNF git checkout directory:

cmake .
./package/build-test-rpm
sudo rpm -i ~/rpmbuild/RPMS/noarch/dnf-<version>-<release>.noarch.rpm

Running tests

From the DNF git checkout directory:

mkdir build;
pushd build;
cmake .. && make ARGS="-V" test;
popd;
