Freezer Specific Commandments

Logging

Use the common logging module, and ensure you getLogger:

from oslo_log import log

LOG = log.getLogger(__name__)

LOG.debug('Foobar')

oslo.config

• All configuration options for freezer-scheduler should be in the following file :

  freezer/scheduler/arguments.py

• After adding new options to freezer-scheduler please use the following command to update the sample configuration file:

  oslo-config-generator --config-file etc/config-generator.conf

- If you added support for a new oslo library, you have to edit the following file adding a new namespace for the new oslo library: for example adding oslo.db:

# edit etc/config-generator.conf
[DEFAULT]
output_file = etc/scheduler.conf.sample
wrap_width = 79
namespace = scheduler
namespace = oslo.log
namespace = oslo.db

This will add oslo.db options to your configuration file.

Agent Options

• All configuration options for freezer-agent should be in the following file :

  freezer/common/config.py

• To list options available in freezer-agent use the following command:

  oslo-config-generator --namespace freezer --namespace oslo.log

Release Notes

- When a new feature is committed we should have a new release notes page that

highlights the changes made. These release notes will be used for deployers, users, and developers. There are a few steps that need to be taken in order.

• Generate a release notes page

  1. tox -e venv -- reno new {my-new-feature}

• Update/Edit an existing release note
