OpenStack Developer Mailing List Digest June 18-24

Status of the Port to Python 3

The only projects not ported to Python 3 yet:

Nova (76%)
Trove (42%)
Swift (0%)

Number of projects already ported:

19 Oslo Libraries
4 development tools
22 OpenStack Clients
6 OpenStack Libraries (os-brick, taskflow, etc)
12 OpenStack services approved by the TC
17 OpenStack services (not approved by the TC)

Raw total: 80 projects
Technical Committee member Doug Hellmann would like the community to set a goal for Ocata to have Python 3 functional tests running for all projects.
Dropping support for Python 2 would be nice, but is a big step and shouldn&8217;t distract from the goals of getting the remaining things to support Python 3.

Keep in mind OpenStack on PyPy which is using Python 2.7.

Proposal: Architecture Working Group

OpenStack is a big system that we have debated what it actually is [1].
We want to be able to point to something and proud tell people “this is what we designed and implemented.”

For individual projects this is possible. Neutron can talk about their agents and drivers. Nova can talk about conductors that handle communication with compute nodes.
When we talk about how they interact with each other, it&8217;s a coincidental mash of de-facto standards and specs. They don&8217;t help someone make decisions when refactoring or adding on to the system.

Oslo and cross-project initiatives have brought some peace and order to implementation, but not the design process.

New ideas start largely in the project where they are needed most, and often conflict with similar decisions and ideas in other projects.
When things do come to a head these things get done in a piecemeal fashion, where it&8217;s half done here, 1/3 over there, ¼ there, ¾ over there.
Maybe nova-compute should be isolated from Nova with an API Nova, Cinder and Neutron can talk to.
Maybe we should make the scheduler cross-project aware and capable of scheduling more than just Nova.
Maybe experimental groups should look at how some of this functionality could perhaps be delegated to non-OpenStack projects.

Clint Byrum would like to propose the creation of an Architecture Working Group.

A place for architects to share their designs and gain support across projects to move forward and ratify architectural decisions.
The group being largely seniors at companies involved and if done correctly can help prioritize this work by advocating for people/fellow engineers to actually make it &8216;real&8217;.

How to get inovlved:

Bi-weekly IRC meeting at a time convenient for the most interested individuals.
openstack-architecture channel
Collaborate on the openstack-specs repo.
Clint is working on a first draft to submit for review next week.

Release Countdown for Week R-15, Jun 20-24

Focus:

Teams should be working on new feature development and bug fixes.

General Notes:

Members of the release team will be traveling next week. This will result in delays in releases. Plan accordingly.

Release Actions:

Official independent projects should file information about historical releases using the openstack/releases repository so the team pages on release.openstack.org are up to date.
Review stable/liberity and stable/mitaka branches for needed releases.

Important Dates:

Newton 2 milestone, July 14

Newton release schedule [2]

Placement API WSGI Code – Let&8217;s Just Use Flask

Maybe it&8217;s better to use one of the WSGI frameworks used by the other OpenStack projects, instead of going in a completely new direction.

It will easier for other OpenStack contributors to become familiar with the new API placement API endpoint code if it uses Flask.
Flask has a very strong community and does stuff well that the OpenStack community could stop worrying about.

The amount of WSGI glue above Routes/Paste is pretty minimal in comparison to using a full web framework.

Template and session handling are things we don&8217;t need. We&8217;re a REST service, not web application.

Which frameworks are in use in Mitaka:

Falcon: 4 projects
Custom + routes: 12 projects
Pecan: 12 projects
Flask: 2 projects
web.py: 1 project
