[keystone] Keystone Team Update - Week of 19 August 2019

# Keystone Team Update - Week of 19 August 2019

## News

### Development focus

Feature freeze as well as a number of other deadlines are fast approaching. The development focus for the next three weeks should be:

* reviews for changes implementing specs:
    - app cred access rules[1]
    - resource options for all resources[2]
    - immutable resources[3]
    - renewable group membership[4]
* finish implementing and reviewing remaining system-scope[5]/default roles[6] migrations (deadline is feature freeze, Sept 9-13)
* reviews for keystonemiddleware and keystoneauth[7] (final release Sept 2-6)
* reviews for python-keystoneclient[8] (final release Sept 9-13)
* helping the requirements team with any requirements issues[9] before requirements freeze (Sept 9-13)
* completing community goals (follow the PDF generation news[10])

Additionally, we're still facing issues with instability of our unit test jobs. Improving the efficiency of our unit tests in order to avoid frequent timeouts would go a long way to helping avoid the feature freeze gate crunch.

### keystoneauth session retries

The heat team reported an issue in keystoneauth[11] where the way in which heat currently uses keystoneauth sessions is unable to take advantage of the request retry logic that is currently exposed only in the adapter. The proposal to fix the issue[12] exposes one of the retry options (connect_retries) in the session object. We've been in discussions on the bug report, on the patch, and in IRC[13][14] about whether this is the best approach and whether it would be better to change the way heat uses keystoneauth (would require a massive rewrite) or to expose the request retry options on the auth plugin in order to localize it to keystone requests (but that's an awkward home for it too). We've also been in disagreement about whether this change constitutes a feature or a bugfix with regards to backportability.
