This is the only approach that is sane...

We would probably consider a backport of that to DevStack Juno, but
Icehouse is effectively EOL and we will be removing that branch soon (days
or weeks, not months).

No.  Even on master you may have issues trying to run a early cycle project
with a late-cycle DevStack.  DevStack evolves to meet the needs of the
projects as they develop.

That Tempest fix is pretty straightforward, with only the one code block
move not being a "skip this if project is not enabled" check.  With
Icehouse EOL, there will be no additional updates so maintaining that
backport in a local private branch should not be a big deal.  You will need
that anyway to keep using icehouse after we remove that branch from the
DevStack repo.

[openstack-dev] [devstack] Use devstack/master to install older releases

[Emmanuel Cazenave]

Hi,

I'm trying to use devstack/master to install older releases of swift and
keystone; the installation fails with a version conflict on pbr.

A little bit of background : I work on a CI that needs to run the swift
functional test suite and the swift part of tempest against swift/icehouse,
swift/ijuno swift/kilo swift/master.

My first approach was to use devstack/icehouse to install swift/icehouse,
devstack/juno for swift/juno, etc

I am now trying to use devstack/master in every cases because I need this :
https://review.openstack.org/#/c/115307/ which allow not to install
nova+glance which I don't need at all, and whose installation takes a
really long time.

So I use devstack/master, and set SWIFT_BRANCH and KEYSTONE_BRANCH to
stable/icehouse for example. The installation  fails because of a version
conflict :
This
https://review.openstack.org/gitweb?p=openstack-dev/devstack.git;a=blob;f=lib/infra;h=3d68e45bd9954a7ce0003d809428c979663d2ede;hb=HEAD#l51
install  the last pbr version, whereas keystone requires pdb<1.0 :
https://github.com/openstack/keystone/blob/stable/icehouse/requirements.txt#L2

I don't now anything about this lib/infra : does it really need to install
unconditionally the last pbr ?
Is my use case of installing older releases with devstack/master not
supported ?

Thanks.
