Proposal for an Architecture Working Group picks up steam

Late the week before last Clint Byrum penned a well reasoned proposal for the creation of an Architecture Working Group – at the time of last weeks Lwood then there had been little discussion.

The thread picked up quite a bit this week just past in what was at times a somewhat impassioned but collegiate discussion – looks like a draft charter will appear for comment in Gerrit before long.

Release naming for P and Q open for nominations

Monty Taylor noted that it’s time to suggest names for the P and Q releases of OpenStack, nominations close at midnight UTC on Wednesday 28 June.  Voting will commence thereafter once the eligibility of names has been checked.

There’s already been a suggestion for “Panda” which may well meet the “really cool but not place name” test :)

Status of the OpenStack port to Python 3

Victor Stinner provided an update on the progress in porting to Python 3. Three projects are yet to be ported – Nova, Trove and Swift, the consensus from the ensuing thread seems to be that it’s too late to be done by Newton but is an achievable and desirable goal for Ocata.

(Answered) What do OpenStack Developers work on upstream of OpenStack ?

Last week Doug Hellman posed the question of what OpenStack Developer work on upstream of OpenStack.

He kindly took the time to collate the results in a blog post. Unsurprisingly it’s a long list and an interesting read to be sure!

Feedback from app developers sought

Piet Kruithof points out that the OpenStack UX project with support from the Foundation and TC are looking to build a community of application and software developers interested in providing feedback at key points during the development process ?

Sound a good initiative, please consider participating!

Announcing What’s Happening in OpenStack-Ansible (“WHOA”)

Major Hayden announced the first of a monthly blog posts he’ll be doing to give an update on what’s happening in Ansible.  It’s a well written read and bound to be of interest to OpenStack Developers and Operators alike.  Major kindly notes that his reading of Lwood was something of a catalyst for starting this endeavour.  Check it out :)

Proposal for an Architecture Working Group

Late in the week Clint Byrum penned a well reasoned proposal for the creation of an Architecture Working Group.  As he puts it “This group’s charge would not be design by committee, but a place for architects to share their designs and gain support across projects to move forward with and ratify architectural decisions. That includes coordinating exploratory work that may turn into being the base of further architectural decisions for OpenStack.”

He goes on to add that his expectation is that people involved in the group would largely be senior at the companies involved and be in a position to help prioritise this work by advocating for resources to be contributed to make the work in question real.

At the time of writing just the one reply to the thread, but a positive one, have a read and see what you think :)

What do OpenStack Developers work on upstream of OpenStack ?

Was the question posed by Doug Hellmann early in the week.  Doug went on to clarify that he was interested to gather information about contributions OpenStack Developers make that “were in some way triggered or related to their work on OpenStack.”

Though the thread is as yet fairly short, in part I suspect because Doug suggested offline replies which he’ll summarise, it’s already an interesting mix.  Folk have noted work on everything from Linux kernel internals, to documentation in other FOSS projects to ISO8601 (I had to look it up too – date and time formats) and a myraid of other things.  Will be interesting to see Dougs summary when it’s published!

Towards ensuring level playing fields for OpenStack Projects

One of the longer threads this week past was kicked off by Thierry Carrez in this post. Thierry outlines some concerns about, in essence, ensuring that new OpenStack projects which seek to become Official projects are unlikely to become overly dominated by any one organisation/company.

From the original proposed change: “The project shall provide a level open collaboration playing field for all contributors. The project shall not not benefit a single vendor, or a single vendors product offerings; nor advantage contributors from a single vendor organization due to access to source code, hardware, resources or other proprietary technology available only to those contributors.”

The review comments in Gerrit are largely positive and my read of the thread itself is the general consensus there is likewise positive – Thierry makes the point that the guidelines are used by humans that interpret them on a case by case basis which should ensure the basic intent is carried out reasonably.

All seems pretty sensible to your humble correspondent :)

A look under the hood of Nova datastructures

If you’ve ever been curious to look under the hood of Nova, Matt Booth put together a nice little summary of his journey through the data structures used in the block device section of same.

There is no Jenkins, only Zuul

How could one not include a thread with such a cool $SUBJECT – particularly with a new Ghostbusters film just around the corner ?

Silliness on my part aside – James Blair gives a concise update on the ongoing work that has seen much of the project automation used in OpenStack migrate from Jenkins to Zuul – the latter being developed specifically with OpenStack in mind.

Notable Discussions – other OpenStack lists

An OPS Cross Project Liaison ?

So asks Lana Brindley in her post to the Openstack-Operators mailing list.  Lana notes that the Docs team have a number of Cross Project Liaisons (CPLs) with OpenStack projects to coordinate documentation related matters but no such person exists on the Operators side – and she seeks volunteers.  Seems a good plan :)

User Research/Usability Study

Also on the -Ops list is an email from Piet Kruithof noting that Danielle Mundle will contributing to upstream by helping to conduct user research on behalf of the OpenStack community.

He goes on to say that “One of her priorities is to begin investigating how operators both learn about OpenStack and triage issues within their deployments.  As a result, you may receive an email invite from the foundation to participate in some form of research such as an interview, focus group or usability study.”

Introduction

Welcome to Last week on OpenStack Dev (“Lwood”) for the week just past. For more background on Lwood, please refer here.

Basic Stats for week 6 June to 12 June 2016 for openstack-dev:

  • ~556 Messages (up about 20% relative to last week)
  • ~191 Unique threads (up about 24% relative to last week)

Traffic up quite a bit this week – back to within about 5% of the long term average.

New OpenStack Security Notice

Nova and Cinder key manager for Barbican misuses cached credentials (OSSN 0063)

From the summary “During the Icehouse release the Cinder and Nova projects added a feature that supports storage volume encryption using keys stored in Barbican. The Barbican key manager, that is part of Nova and Cinder, had a bug that could cause an authorized user to lose access to an encryption key or allow the wrong user to gain access to an encryption key.”

More information and discussion in the original post or the OSSN itself.

Golang not to be given blanket approval for use in OpenStack

While it generated relatively little list traffic in the week past, the TC met and decided not to add golang to the list of official OpenStack development languages.  The door was however left open to accept its use on a project by project basis – in your humble correspondent’s opinion a reasonable middle ground.

The TC meeting minutes are here – the section in question starts at 20:20:04. You can also read the Change in question.  Last but by no means least Monty Taylor posted an eloquent rationale for his “no” vote here and is, I think, worthy of your time to read irrespective of your view on the matter – a nice demonstration of how to express a view on a contentious topic and respect differing views along the way.

StackViz – a neat Visualisation utility

Tim Buckley announced that StackViz has been enabled for all devstack-gate jobs and pointed interested parties at this example output.

As Tim describes it “StackViz is a visualization utility for generating interactive visualizations of jobs in the OpenStack QA pipeline and aims to ease debugging and performance analysis tasks. Currently it renders an interactive timeline for subunit results and dstat data, but we are actively working to visualize more log types in the future.”

The example output looks pretty slick and it’s had some glowing feedback on the list :)

Higgins now Zun

Hongbin Lu gave a heads up that the recently announced container management service Higgins is being renamed to Zun due to some project name overlaps.  The renaming thread itself kicked off late last month here in a post from Shu Mutou.

A quieter week last week on openstack-dev – I suspect at least in part due to holidays in a number of countries in APAC and Memorial Day in the US.  A very short Lwood too – this a mixture of lower traffic and your humble correspondent being a little off colour today.  The latter due in part to a curious combination of Microsoft Windows, helping a mate out with his PC, my forehead and an unexpectedly low cupboard… ;)
