[Bug 2071939] Re: [caraca|2024.1] the 22.0 version of python3-ceilometer is missing files thus breaking the notification service

[Guillaume Boutry]

I built a ceilometer Rock from Noble Proposed and was able to confirm
this fixes the issue.

Built the rock by applying the following diff to
https://github.com/canonical/ubuntu-openstack-
rocks/blob/6707266619e67abe4e1a48ab0fe91e81b6aa5b36/rocks/ceilometer-

I can confirm the notification agent is now starting with the following
logs:

Before the fix, the notification didn't start, failing on the reported exception.

Bug description:
  [Impact]
  Meter definition files are not included in the binary package resulting in a non-functional ceilometer after install.

  [Test Case - Basic]
  sudo apt install python3-ceilometer
  find /usr/lib/python3 -name meters.yaml -> file is not found.

  [Test Case - Advanced]
  Deploy OpenStack Caracal using Charmed OpenStack Tester
  Ceilometer agents will fail to start due to missing data files.

  [Where problems could occur]
  Limited - we're picking a patch that's been in Debian for sometime (2016) so its had good testing exposure already; as to why we need this in Noble whereas in Mantic this problem did not exist - probably something todo with installation behaviour changes between Python versions.

  [Original Bug Report]
  The issue I discovered is that (in an installed system) the:

  /usr/lib/python3/dist-packages/ceilometer/pipeline/data/...

  directory is missing.  This is supplied by the python3-ceilometer .deb
  file.

  For bobcat (mantic):

  $ dpkg -c python3-ceilometer_21.0.0-0ubuntu1~cloud0_all.deb  | grep data
  drwxr-xr-x root/root         0 2023-10-05 19:34 ./usr/lib/python3/dist-packages/ceilometer/data/
  drwxr-xr-x root/root         0 2023-10-05 19:34 ./usr/lib/python3/dist-packages/ceilometer/data/meters.d/
  -rw-r--r-- root/root     13538 2023-10-04 12:09 ./usr/lib/python3/dist-packages/ceilometer/data/meters.d/meters.yaml

  -rw-r--r-- root/root       176 2023-10-04 12:09 ./usr/lib/python3/dist-packages/ceilometer/pipeline/data/event_pipeline.yaml

  drwxr-xr-x root/root         0 2023-10-05 19:34 ./usr/lib/python3/dist-
  ...

  For caracal (noble):

  dpkg -c python3-ceilometer_22.0.0-0ubuntu1~cloud0_all.deb | grep data
  -rw-r--r-- root/root      5113 2024-04-03 12:08 ./usr/lib/python3/dist-packages/ceilometer/tests/unit/compute/pollsters/test_location_metadata.py
  -rw-r--r-- root/root     32485 2024-04-03 12:08 ./usr/lib/python3/dist-packages/ceilometer/tests/unit/ipmi/notifications/ipmi_test_data.py
  -rw-r--r-- root/root     14151 2024-04-03 12:08 ./usr/lib/python3/dist-packages/ceilometer/tests/unit/ipmi/platform/ipmitool_test_data.py

  i.e. the data directory is completely missing.  It is available in the
  upstream ceilometer repo:
  https://opendev.org/openstack/ceilometer/src/branch/stable/2024.1/ceilometer/pipeline/data

  I suspect something is amiss with the package src files.
