Hi,

Here is the status update / focus setting mail about notification work
for week 27.

Bugs
----
[Undecided] https://bugs.launchpad.net/nova/+bug/1684860 Versioned 
server notifications don't include updated_at
Takashi proposed the fix https://review.openstack.org/#/c/475276/ that 
is ready for the cores to look at.

[Low] https://bugs.launchpad.net/nova/+bug/1696152 nova notifications
use nova-api as binary name instead of nova-osapi_compute
Agreed not to change the binary name in the notifications. Instead we
make an enum for that name to show that the name is intentional.
Patch has been proposed:  https://review.openstack.org/#/c/476538/

[Undecided] https://bugs.launchpad.net/nova/+bug/1699115 api.fault 
notification is never emitted
It seems that the legacy api.fault notification is never emited from 
nova. More details and the question about the way forward is in a 
separate ML thread 
http://lists.openstack.org/pipermail/openstack-dev/2017-June/118639.html

[Undecided] https://bugs.launchpad.net/nova/+bug/1698779 aggregate 
related notification samples are missing from the notification dev-ref
It is a doc generation bug. Fix and improvement on doc generation has 
been proposed https://review.openstack.org/#/c/475349/ and reviewed by 
the subteam. So it is ready for the cores to look at.

[Undecide] https://bugs.launchpad.net/nova/+bug/1700496 Notifications 
are emitted per-cell instead of globally
Fix is to configure a global MQ endpoint for the notifications in cells 
v2. Patch is beinf worked on: https://review.openstack.org/#/c/477556/

Versioned notification transformation
-------------------------------------
Couple of patches has been merged but we still have a bunch ready from 
the subteam perspective:
https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/versioned-notification-transformation-pike+label:Code-Review%253E%253D%252B1+label:Verified%253E%253D1+AND+NOT+label:Code-Review%253C0

Searchlight integration
-----------------------
bp additional-notification-fields-for-searchlight
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Two patches merged last week. The BDM addition just needs a second +2 
https://review.openstack.org/#/c/448779/

Besides the BDM patch we are still missing the Add tags to 
instance.create Notification https://review.openstack.org/#/c/459493/ 
patch but that depends on supporting tags and instance boot 
https://review.openstack.org/#/c/394321/ which is still not ready.

Small improvements
~~~~~~~~~~~~~~~~~~
* https://review.openstack.org/#/c/428199/ Improve assertJsonEqual
error reporting
* https://review.openstack.org/#/q/topic:refactor-notification-samples
Factor out duplicated notification sample data
This is a start of a longer patch series to deduplicate notification
sample data. The third patch already shows how much sample data can be
deleted from nova tree. We added a minimal hand rolled json ref
implementation to notification sample test as the existing python json
ref implementations are not well maintained.

Weekly meeting
--------------
The notification subteam holds it's weekly meeting on Tuesday 17:00 UTC
on openstack-meeting-4. The next meeting will be held on 04th of July.
