[RFC] Using gitlab for upstream qemu repo?

[Paolo Bonzini <pbonzini@redhat.com>]

Hi all,

now that Gitlab is the primary CI infrastructure for QEMU, and that all
QEMU git repositories (including mirrors) are available on Gitlab, I
would like to propose that committers use Gitlab when merging commits to
QEMU repositories.

There are four reasons for this:

- this would be a step towards ensuring that all commits go through the
CI process, and it would also provide a way to run the deployment of the
web site via .gitlab-ci.yml.

- right now Gitlab pulls from upstream repos and qemu.org pulls from
gitlab, but this is not true for the qemu, qemu-web and openbios
repositories where Gitlab pulls from qemu.org and qemu.org is the main
repository.  With this switch, all the main repositories would be on
Gitlab and then mirrored to both qemu.org and GitHub.  Having a
homogeneous configuration makes it easier to document what's going on.

- it would limit the number of people with access to qemu.org, since
committers would no longer need an account on the machine.

- by treating gitlab as authoritative, we could include it in the
.gitmodules file and remove load on the qemu.org server

Nothing would change for developers, who would still have access to all
three sets of repositories (git.qemu.org, gitlab.com and github.com).
Committers however would need to have an account on the
https://gitlab.com/qemu-project organization with access to the
repositories they care about.  They would also lose write access to
/srv/git on qemu.org.

Of course this is just starting a discussion, so I'm not even proposing
a date for the switch.
