Placement update 19-12. Nearing 1/4 of the way through the year.
I won't be around on Monday, if someone else can chair the
that would be great. Or feel free to cancel it.
# Most Important
An RC2 was cut earlier this week, expecting it to be the last, but
there are a [couple of
which could be put in an RC3 if we were inclined that way.
We merged a first suite of [contribution
These are worth reading as they explain how to manage bugs, start
new features, and be a good reviewer. Because of the introduction of
StoryBoard, processes are different from what you may have been used
to in Nova.
Because of limited time and space and conflicting responsibilities
the Placement team will be doing a [Virtual
# What's Changed
* The contribution guidelines linked above describe how to manage
specs, which will now be in-tree. If you have a spec to propose or
re-propose (from stein in nova), it now goes in
* Some [image type traits](https://review.openstack.org/648147) have
merged (to be used in a nova-side request pre-filter), but the
change has exposed an issue we'll need to resolve: os-traits and
os-resource-classes are under the cycle-with-intermediary style
release which means that at this time in the cycle it is difficult
to make a release which can delay work. We could switch to
independent. This would make sense for libraries that are
basically lists of strings. It's hard to break that. We could also
investigate making os-traits and os-resource-classes
required-projects in job templates in zuul. This would allow them
to be "tox siblings". Or we could wait. Please express an
opinion if you have one.
* In discussion in `#openstack-nova` about the patch to [delete
placement from nova](https://review.openstack.org/#/c/618215/), it
was decided that rather than merge that after the final RC, we
would wait until the PTG. There is discussion on the patch which
attempts to explain the reasons why.
* The spec for [forbidden aggregate
* The two traits-related specs from stein will need to be
re-proposed to placement for train:
* [any traits](http://specs.openstack.org/openstack/nova-specs/specs/stein/approved/placement-any-traits-in-allocation_candidates-query.html)
* [mixing required traits](http://specs.openstack.org/openstack/nova-specs/specs/stein/approved/placement-mixing-required-traits-with-any-traits.html)
* The spec for [request group
mapping](https://review.openstack.org/597601) will need to be
* StoryBoard stories in [the placement
* Placement related [bugs not yet in progress](https://goo.gl/TgiPXb): 14.
* [In progress placement bugs](https://goo.gl/vzGGDQ) 7. +1.
We should do a bug squash day at some point. Should we wait until
after the PTG or no?
Note that the [contribution
has some information on how to evaluate new stories and what tags to
osc-placement is currently behind by 13 microversions.
* [support for 1.19](https://review.openstack.org/#/c/641094/)
* [support for 1.21](https://review.openstack.org/#/c/641123/)
* [aggregate allocation ratio
# Main Themes
Be thinking about what you'd like the main themes to be. Put them on
# Other Placement
Negative member of aggregate filtering resource providers and
allocation candidates. This is nearly ready.
This is a start at unit tests for the PlacementFixture. It is
proving a bit "fun" to get right, as there are many layers
involved. Making sure seemingly unrelated changes in placement
don't break the nova gate is important. Besides these unit tests,
there's discussion on the PTG etherpad of running the nova
functional tests, or a subset thereof, in placement's check run.
On the one hand this is a pain and messy, but on the other
consider what we're enabling: Functional tests that use the real
functionality of an external service (real data, real web
requests), not stubs or fakes.
