Transform every legacy notification to the new versioned notification framework.

How to do it


Please do not start working on a new task until the currently opened tasks are close to merge to avoid overloading the cores

The easy ones that uses the same payload as instance.delete:

event type status taken by review comments
instance.delete merged gibi https://review.openstack.org/#/c/313654 This shall be the base of for the other instance.<action> transformation
instance.shutdown move to Ocata siva_krishnan https://review.openstack.org/#/c/329214
instance.scheduled open
instance.create_ip move to Ocata antal https://review.openstack.org/#/c/332876/ renamed to add_fixed_ip to be more precise
instance.delete_ip open rename it to remove_fixed_ip
instance.evacuate open
instance.migration open
instance.pause merged sneti https://review.openstack.org/#/c/329141/
instance.unpause open sneti
instance.power_on merged zhs https://review.openstack.org/#/c/329746/
instance.power_off move to Ocata xenogear https://review.openstack.org/#/c/330761/
instance.reboot mova to Ocata macsz https://review.openstack.org/#/c/330224/
instance.reboot.error open
instance.shelve merged vancsics https://review.openstack.org/#/c/332696/
instance.shelve_offload open
instance.unshelve open
instance.snapshot move to Ocata syjulian https://review.openstack.org/#/c/330128/
instance.soft_delete open
instance.suspend merged pumaranikar https://review.openstack.org/#/c/329089
instance.resume open siva_krishnan
instance.restore needs work zhs https://review.openstack.org/#/c/331972/
instance.trigger_crash_dump open
instance.unrescue open
instance.create open Some of the instance.create.<phase> notifications has extra payload
instance.rebuild open pumaranikar
instance.rebuild.scheduled open we might need to change the event_type
instance.resize merged aunnam https://review.openstack.org/#/c/329255/
instance.resize.error open
instance.resize.prep open we might need to change the event_type
instance.finish_resize open we might want to change the even_type
instance.resize.confirm open
instance.resize.revert open
instance.live.migration.abort open we might need to change the even_type to make it consistent
instance.live_migration.pre open we might want to change the event_type
instance.live_migration.rollback.dest open we might want to change the event_type
instance.live_migration._rollback open we might want to change the event_type
instance.live_migration._post open we might want to change the even_type
instance.live_migration.post.dest open we might want to change the event_type

The complex instance.<action> notifications that needs payload extension.

event type status taken by review comments
instance.update merged gibi https://review.openstack.org/#/c/325923/ This shall be the example for creating instance.<action> notification with extended InstancePayload
instance.exists open
instance.rescue open
instance.volume.attach open

The rest:

Follow up tasks

Mostly for after N-2

  • add a reno note about the transformed notifications
  • rlrossit will remove the vm_state - InstanceState value duplication
  • improve doc generation, include a sample link in the doc that is valid also before the sample adding patch is merged. (look at the api-ref doc work for ideas)

* separate the notification object unit test from the nova object version test. Done

* replace set_override with self.flags in https://review.openstack.org/#/c/332696/5/nova/tests/functional/notification_sample_tests/test_instance.py

In Ocata:

  • after the json schema patch is merged in ovo and a new ovo lib version is released we can add a tool to nova generate the json schemas for the versioned notifications.
