Placement update 19-13 is brought to you by the letters P and U.

# Most Important

The [Virtual
Pre-PTG](http://lists.openstack.org/pipermail/openstack-discuss/2019-March/004225.html)
starts next week. Watch out for emails to start different threads
throughout the week. Also next week there will be a Nova pre-PTG
[spec
review](http://lists.openstack.org/pipermail/openstack-discuss/2019-April/thread.html#4484).
Plenty of the pending work touches on placement.

In the meantime here are a couple of etherpads for the PTG:

* <https://etherpad.openstack.org/p/placement-ptg-train>
* <https://etherpad.openstack.org/p/ptg-train-xproj-nova-placement>

# What's Changed

* There were some lingering docs and log fixes so we released an RC
   3 of Placement. That candidate will become 1.0.0 on April 10th.

* Microversion 1.32, for [forbidden
   aggregates](https://docs.openstack.org/placement/latest/placement-api-microversion-history.html#support-forbidden-aggregates)
   merged.

* We've decided it would be nice to a) release os-traits and
   os-resource-classes in an independent fashion and, b) make them
   available to both placement and nova as tox-siblings. We'll do (a)
   once release time settles. For (b) the strategy is still a bit up
   in the air. There's some [email
   discussion](http://lists.openstack.org/pipermail/openstack-discuss/2019-April/004424.html).

# Specs/Features

* Two traits related specs have been re-proposed to Train, following
   the [new
   process](https://docs.openstack.org/placement/latest/contributor/contributing.html#new-features).

     * <https://review.openstack.org/649992>
       Spec: support any trait in allocation candidates

     * <https://review.openstack.org/649368>
       Spec: support mixing required traits with any traits

* As before, the spec for [request group
   mapping](https://review.openstack.org/597601) will need to be
   revisited.

# Bugs

* StoryBoard stories in [the placement
   group](https://storyboard.openstack.org/#!/project_group/placement): 6.
   0 are
   [untagged](https://storyboard.openstack.org/#!/worklist/580).

* Placement related [bugs not yet in progress](https://goo.gl/TgiPXb): 13.
   -1.

* [In progress placement bugs](https://goo.gl/vzGGDQ) 5. -2.

Once Stein has settled, we'll figure out a good time to have a bug
cleanup and consolidation.

# osc-placement

osc-placement is currently behind by 14 microversions. +1 since last
week.

Pending changes:

* [support for 1.19](https://review.openstack.org/#/c/641094/)
* [support for 1.21](https://review.openstack.org/#/c/641123/)
* [aggregate allocation ratio
   tool](https://review.openstack.org/#/c/640898/)
* [stack to fix docs and
   classifiers](https://review.openstack.org/650093)

# Main Themes

Be thinking about what you'd like the main themes to be. Put them on
the [PTG
etherpad](https://etherpad.openstack.org/p/placement-ptg-train).

# Other Placement

* <https://review.openstack.org/#/c/645255/>
   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.

* <https://review.openstack.org/641404>
   Use ``code`` role in api-ref titles

* <https://review.openstack.org/649618>
   Removing some unused code.
