Open Stack

Hi Emilien,

I can see why you might be unhappy with Fuel's actions with regards to
the OpenStack Puppet modules. You could make this argument about many
components in Fuel. The heart of the matter is that we bundle the
upstream OpenStack Puppet modules with all the other modules,
developed both upstream and by Fuel's developers in one single git
repository. This decision, along with all the other decisions to put
Fuel's components under its own repositories, was intended to add
stability and granular control to the product. I'm not saying it's the
most community-oriented approach, but Fuel would have never evolved
and matured without it. The attribution in commits is lost because our
directory namespace differs such that it can't just be merged cleanly.
Revisiting submodules is an option, but it led to maintenance problems
in the past.

Secondly, I'd like to point out that Fuel is not so different from
what other teams are doing. At the Summit, I heard from others who all
maintain internal Gerrits and internal forks of the modules. The
difference is that Fuel is being worked on in the open in StackForge.
Anyone is free to contribute to Fuel as he or she wishes, take our
patches, or review changesets.

Starting in October 2014, the Fuel team has adopted a policy that we
cannot merge any patches into the core Puppet OpenStack modules of
Fuel without submitting a patch or at least a bug upstream. Our
reviewers block patches consistently. The truth is that the upstream
modules are quite excellent and we don't need to make changes so
often. Our goal is to work with upstream modules or in the issue where
upstream integration is impossible, we place that config in our own
separate modules.

The point you raised about fixing bugs in Fuel and not in Puppet
OpenStack is definitely valid and something we need to collaborate on.
The first and easiest option when a bug is applicable to both, we
could use Launchpad to assign bugs to both Fuel project and
puppet-$project so it gains visibility. If a bug is discovered in
Puppet OpenStack after it's been reported and/or fixed in Fuel, then
it would be best to ping someone in #fuel-dev on IRC and we can try to
figure out how to get this applied upstream correctly. Our best
results come from fixing upstream and I want to make sure that is
clear.

If you have specific bugs or commits you'd like to discuss, let's work
them out. I believe I can get the Fuel Library team to agree to do a
walk through all the open bugs in Puppet OpenStack and see if we have
any related fixes or bug reports.

Best Regards,
Matthew Mosesohn
