Hi Kyle,

I recall talking to you and “lifeless” about an issue with pbr
versioning in stable/kilo for networking-odl.

That seems to be an issue [1], still; making it impossible for
folks to use networking-odl with stable/kilo.

Assuming that pbr version in stable/kilo is not changing, do you
think that gerrit 204211 [2] could be restored and merged into
stable/kilo? Or maybe there is a better alternative?

Thanks,

Hi ODL Netvirt experts (Flavio, Sam, etc.),

I’m trying to setup OVSDB Netvirt with Openstack stable/kilo
2015.1.1 On Fedora 21 systems – not the vagrant/vm based
examples.

The problem appears to be around version requirements for a
python pbr package.

Are there any known resolutions or hints for this issue?

I am using the 2015.1.1 tag for most of the openstack packages,
or stable/kilo branch for the ones that don’t have that tag.

Using the stable/kilo branch of the networking-odl driver, I get
the following error when trying to stack (devstack):

So why can't your machine download the satisfying pbr version?
It's available on pypi, so assuming you fix the download error, I
think it should proceed.

That is the issue. This happens because OFFLINE=True and there
is still something in pbr requirements that is looking for a
version of pbr that is not used in stable/kilo.

I suspect this is happening because stable/kilo branch in
networking-odl was created ‘late’ and the new version of pbr was
added as part of liberty?!?

So, to easily reproduce this issue: 1) stack with
devstack+networking-odl on stable/kilo; 2) untack; 3) change
OFFLINE=True and 4) attempt to stack again.

Are your repo [test-]requirements.txt synchronized with neutron's
kilo requirements? They should, otherwise it won't be ever
supported.

They do not for requirements.txt:

$ diff requirements.txt.neutron requirements.txt.networking-odl |
grep pbr < pbr!=0.7,<1.0,>=0.6

pbr<2.0,>=1.3

$ diff test-requirements.txt.neutron
test-requirements.txt.networking-odl | grep pbr $

If you look closely, that is what is changed in the abandoned
gerrit [1]. Maybe the right thing to do is to re-visit that
gerrit and make sure the requirement.txt files are inline?!?

indeed!

The fix is obvious: make stable/kilo requirements in your repo
synchronized with what is in stable/kilo for neutron. Same for all
other branches.

Openstack requirements proposal bot can help you maintain the
lists synchronized. To make sure your repo gets updates from the
bot, add it in projects.txt in openstack/requirements repo (in
master and in stable/kilo).

It is ironic reading this… and then looking at the ‘owner' of the
commit that caused all this mess [1].

That aside; I have very little experience on that… some one
else’s help to take care of this would be greatly appreciated.

Anybody of for that task?

The bot was proposing when it was still master. After you branched
out stable/kilo, you should have sticked to the deps that belong
to stable/kilo.

one else’s help to take care of this would be greatly
appreciated.

OK, so your repo is in projects.txt, but only on master. That's
why you don't receive updates on stable/kilo. I've cherry-picked
the appropriate openstack/requirements patch to enable the bot for
your stable branch too: https://review.openstack.org/#/c/213084/

I see that you created stable/kilo branch based on some incorrect
hash that already included changes from liberty cycle. That's why
you got the bot requirements update there. You should probably
reset your branch to start from a patch that does not include any
Liberty changes.

yes, make sense. How and where is this hash kept? I think
whatever hash it has now is fine, except for the gerrit I propose
to be reverted [1]. @Kyle: agree?

One other glitch I see in your repository is that you have
stable/juno and stable/icehouse there while they contain neutron. I
guess they were created when you spinned out your driver out of
neutron tree. I think they can be safely killed now.

Yes. Can you give me more concrete steps on how to accomplish
that ‘killing'?

I can get rid of those branches in gerrit, let me do that now.
