Hello Vladimir,

Unless mistaken, we never had any follow-up on your help proposition.
We are still very interested in any help on automatic testing
procedures. Our current continuous builds have been really shaky these
last months, with server issues for months at a time, and such. We
would appreciate some stable and reliable CI. Even more now that GIMP
2.10 release is approaching fast.

Are you still interested by this topic at Red Hat?
We would welcome any collaboration on the topic. :-)

I am really sorry that I haven't responded. We had some personal changes
in the team and it somehow slipped under the table.

No prob.

Anyways, we are in the process of moving some of our automation to CICO
(CentOS CI) which seems to be pretty stable and what's more interesting,
it's public!

And I see that's Jenkins, which is already what we are using. So I
guess that means it should not be too hard to migrate all our current
builds as is (no?).

I have started with NetworkManager

It should be pretty well integrated with github and ansible and it's
possible to build other non CentOS environments on top of CentOS
installation (via vagrant or so). I think it's just a matter of being
able to compile without special efforts, right? CentOS and epel should
be pretty stable env.

Yes compiling, run the tests, send appropriate warnings when a build
fail for us to check logs… Currently we have a IRC bot which tells us
build results (so that we can know immediately when a build fails).
And be reliable. That's the base. :-)

Just to be sure, you are not only proposing us an infrastructure, but
also to maintain the builds, right?

Just the infrastructure would already be awesome, but what we are
especially lacking are contributors and active CI maintainers. As
often developers are not really interested into spending too long on
administrating CI servers, though we definitely appreciate that there
is one! So we really hope your proposition includes maintaining the CI
instance, and if a build breaks for non-code reason (or at least we
think it's not the code!), someone on your side can look into it
quickly. :-)

Of course we'd still appreciate if we can have logins to be able to
log into the CI instance, though we are definitely not planning into
interfering much with the build maintainers.

I will discuss this more with my manager and we will prioritize things
accordingly. I think that moving our code a bit more towards community
(and into public) and you maybe moving your code to reach more stability
to some other env can intersect in CICO. Who knows! CICO seems to be
pretty beefy and equipped with hundreds of bare-metal machines and also
in the process to enable cloud (openstack based) provisioning soon.

Looks very nice. I hope that will work out!

I will keep you updated how NM goes and we can do something about GIMP
too. The biggest concern in our team here was the C code. We are not
much into C as we are pretty more python/gherkin/shell oriented. But if
sanity test code is actively maintained by developers we can deliver
some more integration tests on top of it ideally in the same CI system.

Our code is actively maintained. Our test process could be better, but
we do make sure tests always pass and take it seriously (our current
CI does a make check and we fix any broken tests as quickly as we can,
upon discovering them).

Does it make sense? Ideas?

Yes it does completely make sense. On our side, I think we will all
agree that if you can propose us a process to make your team our new
CI maintainers, we'd be happy to. Our contribution logics is really
that doers are in command.


P.S.: I think I can create new read users onto our current Jenkins
instance so I could give you access if needed be for exporting jobs or

Hi all,
we (at Red Hat) are very interested in GIMP as we do use it and we also
do test it (but not the latests releases). We would like to start or
participate in an automated testing efforts of upstream releases or
possibly master branch. I am not sure if you have anything ready for
automated testing of latest code but I wasn't able to find anything. We
do have some basic test set in-house but coverage is really far away
from ideal and as we have some resources to invest it would be nice to
properly cooperate in upstream directly.
We would be quite interested to set up a CI system if there is none or
possibly use GNOME continuous if applicable. Definitely open to ideas

We actually already have a server running Jenkins at for CI. This said, there is currently only one
administrator (Sam Gleske, aka "samrocketman" on IRC) for this server,
and depending on his personal schedule (voluntary contributions), we
happened to have extended periods of time (sometimes up to months)
with the continuous integration broken.

Therefore I guess we would be happy to cooperate. You should get in
touch with Sam. What we discussed recently with Sam was:

1/ We'd like more administrators to share the work because when the
build server gets broken for months without anyone able to do anything
about it, that sucks. And such unreliability makes it useless for even
thinking about more advanced uses.

2/ We'd like to have as much of the CI process, scripts, and
everything documented (probably in a versionned repository) so that
developers are able to at least understand, access and maintain the
system a minimum when system admins disappear (less a problem with
several admins of course), and so that the job can be passed along
when needed. I'd like to avoid black box issues.

Basically our first goal is to make our system more reliable and
transparent. These are our main worries right now regarding CI.

As for coding style we are quite happy users of python Behave [1]
framework in not only GNOME projects using Dogtail [2] over a11y layer
or some kind of expect [3] if tests are cli based. For the code
readability and easiness to code we do use python to connect all these
A good example of such code is in gnome-calculator [4] in feature files
or in gnome-boxes [5].

I think, us developers, are opened to ideas improving our continuous
integration, on server side and in new tests in our build system. Just
propose us what you have in mind.

Once again, I think what really matters to us is reliability: if
something is done, it must be meaningful, maintained and not break
tomorrow. CI is meant to help development, not become a burden to us.
Obviously contributions from RedHat, I would expect some good level of
maintenance. So we are definitely interested.

If you have any ideas where our cooperation should start or if you have
something ready and just not visible to us please point me to the right

Well you are welcome to propose us something, on the mailing list, or
through a bug report… And probably coming discuss this on IRC (#gimp
on would be a first step.
The point is that any idea on this topic will rather be your level of
expertise (or Sam's) than ours, so we are open to suggestions.
