[Rpm-ecosystem] Locating all the RPM Ecosystem software

[Neal Gompa]

Hello all,

I was chatting with Florian Festi in #rpm.org earlier today, and it led me
to bring up the question of where all the tools that actually make up the
common tools and features of RPM, Yum, and DNF actually are.

So, as it turns out, the answer is: all over the place (and in one case,
almost nowhere).

The first (and most important one) is DeltaRPM. Most distros using DeltaRPM
technology are currently using the deltarpm package written by SUSE. That
*was* on Gitorious. However, Gitorious was acquired by GitLab and the
system was shut down. It "is migrating all the repositories to Internet
Archive," but it's been doing that for a while, and it effectively means
that it's disappeared for now.

That said, I was able to locate a mirror that someone made just before the
shutdown: https://gitlab.com/necrose99/deltarpm

I would like to suggest that a new master tree for this application be
hosted on the rpm-software-management GitHub organization.

Next up are the libraries used by DNF: libsolv, hawkey, librepo, and
libcomps.

hawkey and libcomps were easy to find, as they are in the
rpm-software-management organization on GitHub.

I poked around a bit and found librepo on GitHub. Assuming this is the
canonical source (I think it is), it's at: https://github.com/Tojaj/librepo

Florian pointed me to libsolv's location on GitHub (under the openSUSE
organization): https://github.com/openSUSE/libsolv

Great, we're done, right? Not quite. We've got all the pieces now for
package creation and management, but what about repository creation and
management?

For rpm-md repository data (which is all Yum and DNF currently support),
the "createrepo" package does this.

However, there are two variants of createrepo.

The first variant is the Python based one: createrepo. This variant is
hosted on its own site (http://createrepo.baseurl.org/) and its source code
is hosted on a local GitWeb there.

The second variant is a C based one: createrepo_c. This variant is intended
to be command-compatible with createrepo, but faster and more accurate on
repository creation and management. It is hosted on GitHub at:
https://github.com/Tojaj/createrepo_c

However, for DeltaRPM support, createrepo_c doesn't use deltarpm. Instead
it uses libdrpm, which is hosted by Fedora at:
https://git.fedorahosted.org/git/drpm.git

After trawling through this, I came away somewhat dissatisfied with how
scattered things are. I would like to see if we could potentially move some
more of these things to the rpm-software-management organization on GitHub
so that it's easy to find all the tools people need for making and managing
an RPM-based distribution.

Thoughts?
