Interesting!  Looks quite useful.  Are you doing anything with
respect to the "jhbuild sysdeps --install" infrastructure or is
the system package set maintained manually?

Yeah, up to gtk+ at least.  

The gnome-control-center failure appears to be something in the
jenkins/jhbuild glue not understanding how to properly do git

That's one factor.  It's also not building apps.  A further nontechnical
factor is that I watch the builds like a mother with a
newborn baby...

So...tests.  An interesting and complex topic.  I've had a document
started about this for a while:

Pretty soon, once I finish up some infrastructure, I'll have the key
"smoke test" - does the system boot in a standard qemu configuration,
with no core dumps or fatal service errors, successfully logging into


This should all be pretty fast - I want this test running within 5
minutes after I push a commit to glib/gjs/whatever.  And 5 minutes is
slow - with some optimizations, that could be 1 minute.

*After* that test has completed, we can do stuff like run selected tests
from glib/pygobject/gjs etc.  In the installed test model, we can choose
exactly which one of those tests to run.

I know this installed tests model is orthogonal (somewhat complementary,
somewhat conflicting) to the work you've been doing for the current
"distcheck" model of nondestructive per-user tests.  It's true that
those types of tests can be very easy and fast for developers to run.  

But the qemu-based testing model is very powerful, and there's no excuse
for not having a suite of qemu-based tests run automatically build
server side.
