Please define what you mean by "proper packages" here. I *think* you might
mean system packages (aka Debian or Red Hat) which is not feasible given
other environments that Horizon runs under. Please correct me if I'm wrong!

We're going to have potential breakage (gate breakage, in the integrated
tests) any time we release a package (regardless of release mechanism) and
have to update two separate repositories resulting in out-of-sync version
specification and expectation (ie. upper-constraints specification and
Horizon's code expectation) as described in my OP. The only solution that
we're aware of is to synchronise updating those two things, through one of
the mechanisms proposed so far (or possibly through a mechanism not yet
proposed.)


I think that David's proposal is the only really feasible approach at this
time:

1. Horizon maintains its own constrained version list for the xstatic
packages,
2. Plugins to Horizon must depend on Horizon to supply xstatic packages
except where they use additional packages that Horizon does not use, and
3. We avoid installing app-catalog (the system, not the plugin) in the
integrated tests (I don't believe doing this is even on the ... "horizon"
so to speak) *or* in a Debian / Red Hat (i.e. system-packaged) system that
also has Horizon installed. Or we try to convince app-catalog to stay
lock-step with Horizon's xstatic versions. I understand the risk of a
collision between app-catalog and Horizon in the same system-packaged
environment is very low.
