Hi Romain,

I’ve applied the whole series to Cuirass:

  81d2530 * http: Add /admin/gitlab/event.
  10cf59f * gitlab: Add module for Gitlab JSON objects definition.
  1da873b * specification: Ensure name is a symbol.

I took the liberty to merge the commit that adds test with the one that
defines the HTTP endpoint, and I also added a comment at the top of
gitlab.scm giving context.

For those following along: Romain and I work together at Inria.  This
feature will allow us to hook Cuirass into GitLab so that merge requests
on the channels hosted at https://gitlab.inria.fr/guix-hpc trigger
builds on https://guix.bordeaux.inria.fr (technically, it adds a new
“spec” that gets deleted once the merge request is merged).

We still need to figure out how to get the build result back into
GitLab, but that’s a start.

Feedback welcome!

Thanks,
Ludo’.

After doing some more testing, we realized the string/symbol migration
introduced type errors (statically-typed language programmers would be
right to laugh at us here, I admit).  It’s not fixed in ‘main’ yet, but
we’ll be looking into it in the coming days.

Cheers,
Ludo’.

Nah because the new feature is really nice! :-) Thanks.  But it
remembers me one of our first in-person discussion back then on December
2018… My 6-years patience is paying off. ;-)

Cheers,
simon
