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
======================

All commands should be run from the DNF git checkout directory.

To install the build dependencies::

sudo dnf builddep dnf.spec

To build DNF::

mkdir build;
pushd build;
cmake ..; # add '-DPYTHON_DESIRED="3"' option for Python 3 build
make;
popd;

To run DNF when compiled for Python2::

PYTHONPATH=`readlink -f .` bin/dnf-2

To run DNF when compiled for Python3::

PYTHONPATH=`readlink -f .` bin/dnf-3

If you want to build the manpages, use the option ``-DWITH_MAN=0`` with cmake.

Man pages will be located in ``build/doc`` and can be read with ``man -l``, e.g::

man -l build/doc/dnf4.8

=============================
Building and installing rpm
=============================

From the DNF git checkout directory::

$ tito build --test --rpm
# dnf install /tmp/tito/noarch/*

===============
Running tests
===============

From the DNF git checkout directory::

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

==============
Contribution
==============

Here's the most direct way to get your work merged into the project.

1. Fork the project
#. Clone down your fork
#. Implement your feature or bug fix and commit changes
#. If the change fixes a bug at `Red Hat bugzilla `_, or if it is important to the end user, add the following block to the commit message::

= changelog =
msg: message to be included in the changelog
type: one of: bugfix/enhancement/security (this field is required when message is present)
resolves: URLs to bugs or issues resolved by this commit (can be specified multiple times)
related: URLs to any related bugs or issues (can be specified multiple times)

* For example::

= changelog =
msg: Verify GPG signatures when running dnf-automatic
type: bugfix
resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1793298

* For your convenience, you can also use git commit template by running the following command in the top-level directory of this project::

git config commit.template ./.git-commit-template

#. In special commit add your name and email under ``DNF CONTRIBUTORS`` section in `authors file `_ as a reward for your generosity
#. Push the branch up to your fork
#. Send a pull request for your branch

Please, do not create the pull requests with translation (.po) files improvements. Fix the translation on `Fedora Weblate `_ instead.

===============
Documentation
===============

The DNF package distribution contains man pages, dnf(8) and dnf.conf(8). It is also possible to `read the DNF documentation `_ online, the page includes API documentation. There's also a `wiki `_ meant for contributors to DNF and related projects.

====================
Bug reporting etc.
====================

Please report discovered bugs to the `Red Hat bugzilla `_ following this `guide `_. If you planned to propose the patch in the report, consider `Contribution`_ instead.

Freenode's irc channel ``#yum`` is meant for discussions related to both YUM and DNF. Questions should be asked there, issues discussed. Remember: ``#yum`` is not a support channel and prior research is expected from the questioner.
