Luke has been an excellent contributor to the Security project and would be
an excellent PTL to take the project forward.

I am curious too. I've been bothered by some of the compromised we've had to
make based on some people claiming CD from master is a "core tenet from the
beginning of OpenStack". But I have yet to find anywhere that we've stated
that we will commit to making continuous deployment from master a) possible,
and b) supported.

I would like us to either clearly declare that that type of deployment is
possible and expected and that the community agrees to support it, or that
it is possible for folks to try, but it will be on them if things don't work
out the way the had hoped.

Like I mentioned, we've made compromises based on this assertion, and I really
don't like that we've sacrificed good design and quality in order to support
a scenario that, as far as I've seen, 90+% of users and deployers would run
screaming from.

I thought it would be natural for OSC to adopt the SDK someday if
Brian did not get around to making it official, but the current
circumstances make it clear that we (OSC) do not have the resources to
do this.  This proposal is much better and leads to a natural
coalescence of the parallel goals and projects.


Doing that implies the following:

* Rework the underlying guts of openstacksdk to make it possible to replace
shade's REST layer with openstacksdk. openstacksdk still doesn't have a 1.0
release, so we can break the few things we'll need to break.


Sigh.  OSC has been using the Network components of the SDK for a long
time in spite of SDK not being at 1.0.  In retrospect that was a
mistake on my part but I believed at the time that 1.0 was close and
we had already ignored Network for far too long.  We already have one
compatibility layer in the SDK due to the proxy refactor work that was
supposed to be the last thing before 1.0.


I don't think we need to break the things you're using, fwiw. In fact, 
we can probably take it as a first-order requirement to not break OSC - 
unless we find something SUPER intractable - and even then we should 
talk about it first.

* Merge the two repos and retire one of them. Specifics on the mechanics of
this below, but this will either result in moving the resource and service
layer in openstacksdk into shade and adding appropriate attributes to the
shade.OpenStackCloud object, or moving the shade.OpenStackCloud into
something like openstack.cloud and making a shade backwards-compate shim. I
lean towards the first, as we've been telling devs "use shade to talk to
OpenStack" at hackathons and bootcamps and I'd rather avoid the messaging
shift. However, pointing to an SDK called "The Python OpenStack SDK" and
telling people to use it certainly has its benefits from a messaging
perspective.


I don't have a big concern about which repo is maintained.  For OSC I
want what amounts to a low-level REST API, one example of which can be
found in openstackclient.api.*.  Currently Shade is not quite the
right thing to back a CLI but now has the layer I want, and SDK does
not have that layer at all (it was proposed very early on and not
merged).


FWIW - now that we landed version discovery and microversion support in 
keystoneauth - I'd say keystoneauth Adapter is actually now the 
low-level REST API:


  client = keystoneauth1.adapter.Adapter(
session=session,
service_type='compute',
region_name='DFW',
min_version='2',
max_version='2.latest')
  endpoint_data = client.get_endpoint_data()
  print(
"Microversion range is: ",
endpoint_data.min_microversion,
endpoint_data.max_microversion)
  # want 2.31 of servers
  server_response = client.get('/servers', microversion='2.31')
  server = server_response.json()['servers'][0]
  # want 2.14 of keypairs
  keypair_response = client.get('/keypairs', microversion='2.14')
  # Don't care on volume attachments - don't specify one.
  volume_attachments_response = client.get(
  '/servers/{id}/os-volume_attachments'.format(id=server['id']))

I appreciate that this specific case you view as being in that
category, I was commenting more on the general case. I would go so far
as to outline exactly what we wont break for markers in-between
releases rather than what you've implied. I can come up with exactly
one case that should never be broken between releases (fixes that
change no behavior but address edge cases are fine): DB Schemas.

I am going to continue to say we cannot and should not commit to
treating anything that lands as a contract, it devalues the release
and ability of the developers to make shifts while working on a
release.

You and I may not agree here, but tracking master has risks and we
should allow for projects to make API changes for un-released APIs as
they see fit without version bumps.

Thanks for the feedback for this fix in specific, I think we came to
much the same conclusion in IRC but wanted some outside eyes on it.

Cheers,
--Morgan

In my view, following master imposes risks that deployers should
understand and be prepared to mitigate; but I believe that it is our
responsibility to acknowledge that they're doing it, and make a
reasonable effort to not break them.  There are, of course, times when
no reasonable effort will avoid breaking them, and in those cases, I
feel that the reasonable course of action is to try to notify them of
the upcoming breakage.  That's why then I went on to suggest that
fixing this problem in keystone shouldn't require a version bump in
this case: it _is_ a breakage that's being fixed.

I am going to go out on a limb and say that we should not assume that
if code merges ever it is a contract because someone might be
following master. The contract should be for releases. We should do
everything we can to avoid breaking people, but in the case of an API

This is just my $0.002 as this leads rapidly to "why bother having

The problems seem to be more with the use of entrypoints and the
incredible runtime cost for using them (which you've hinted at in
entrypointer's README). I don't think switching from $plugin lib to
$otherplugin lib changes much for tools like openstackclient unless we
first fix entrypoints (or avoid entrypoints all together). Until then
you must still rely on entrypoints to scan your python path which is
slow.

Yeah, but you still run into stuff like db contact and driver information being

Sure. It's already possible today to use multiple configuration

I would be inclined to accept this specific change as a bug fix not
requiring a version bump, because it is a corner case that I believe a
deployer would view as a bug, if they encountered it, and because it
was introduced prior to a named final release.

I don't have a big concern about which repo is maintained.  For OSC I
want what amounts to a low-level REST API, one example of which can be
found in openstackclient.api.*.  Currently Shade is not quite the
right thing to back a CLI but now has the layer I want, and SDK does
not have that layer at all (it was proposed very early on and not
merged).

Is it better to have a single monolithic thing that has three
conceptual layers internally that can be individually consumed or to
have three things that get layered as needed?

As I mentioned, we already use the Networking portions of SDK, even
without a 1.0, and it has bit us already a couple of times.  It has
long been my plan to convert to using the SDK, but that was when I
believed there would also be a lower-level API exposed that did not
require all of the application-level goodness and abstractions.

I personally feel like splitting out the low-level REST API layers
into a stand-alone piece that shade, SDK and OSC can all benefit from
would be our best course, but then I have been wrong about this
layering thing in the past, so I throw it out there to have something
that can be used to push against to get what everyone else seems to
want.

Exactly, this is also one of the goals to have continuous tracing in place
i.e. to have minimal tracepoints active and increase the granularity to
learn more information or pin down the problem.

Thanks. Monitoring is the major goal here. It's more focused on the user
and operational experience than the developer community.
Integrating this with services like rally may help the operations people
identify the hot spots and bottlenecks in the system. Automating this may
help with finding the anomalies in the system as one of many other usages.
Developers may get to know the impact the changes will make on the current
system across various services that interact. However, I totally agree that
it won't make any changes to the current architecture. It will just help to
set the baseline to further changes.

Thanks

Good call - with that in mind I would be inclined to say we should fix
the issue in Pike that way we keep the 204 -> 204 behavior the same
across releases. But I'll defer to someone from the API WG just to make
sure.

Sure. It's already possible today to use multiple configuration

Is this the case even if we haven’t made any final release with the change
that introduced this issue? [0]

It was only included in the Pike milestones and betas so far, and was not
part of the Ocata release.

Therefore the call which now returns a 403 in master, returned a 2xx in
Ocata. So we would be fixing something which is broken on master rather
than changing a ‘contract’.

Completely agree. I'm more interested in changing the process around this than
the policy. I would hope we would never get beyond the single digits in number
of string changes during soft string freeze. If that happens, we are likely
letting too many trivial things through than we should at this point.

I'm not sure how many folks are on the openstack-i18n mailing list. As the
mail manager informed me shortly after sending my last reply, I am not so my
copy to that list was rejected. It might be better to keep it on -dev.

Although we are really trying to get the attention of the i18n team. Maybe
we could make it a requirement that each project's PTL (or designated i18n
liason) be subscribed to that mailing list in order to submit the notice of
string changes allowed during soft freeze.

Totally agree. Hard freeze should be a hard freeze. Only if there is a last
minute critical fix that absolutely must get through would be the only reason
I would want to see string changes allowed. And that better be a very rare
thing.

[openstack-dev] [keystone] [keystone] [ptl] PTL candidacy for Queens

2017-08-04 Thread Lance Bragstad
*

Hi all,

**

I'd like to formally communicate my desire to continue serving as the
keystone PTL for the upcoming Queen’s release. Despite some turbulence
throughout the Pike development cycle, keystone has managed to make
progress on some long standing issues. Even though the pace of
development has decreased, I think we can build momentum from the small
victories in Pike and have a productive Queens release. I'd like to
direct our focus on the following areas for continued improvement and
stability of the keystone project throughout the Queen’s cycle.


  Policy Improvements

We dedicated a significant portion of our time this release getting
policy into code and documented. We also had meaningful discussions with
operators and developers, resulting in a plan that improves
long-standing issues with OpenStack policy enforcement. I'd like to
carry this momentum into Queens and ensure we’re implementing global
role assignments. Additionally, I'd like to work closely with the oslo
team to find ways we can signal deprecations to operators though the
oslo.policy library. This will help us define a better set of default
roles in Rocky, and clean-up policy enforcement at each service. Lastly,
I look forward to championing the community goal to move policy and
documentation into code for all applicable projects.


  Application Credentials

At the forum and while reviewing the specification, we realized just how
important this work is to our users. While it's unfortunate we didn't
make as much progress here as we hoped during Pike, the discussions this
cycle highlighted a lot of concerns with design as well as usability. I
think we're all better off and more prepared to address the last few
tough design bits during the PTG. One of my goals during the PTG is to
facilitate those conversations and verbosely communicate our approach. I
think that will help us keep the goal in mind as we drive towards
delivering this in Queens.


  Unified Limits

Addressing unified limits was another long-standing issue that we did a
good job of capturing and documenting throughout the Pike release [0].
Pending available resources, it would be great to push this forward,
starting with unified limits in keystone. This will have a positive
impact on any project currently experiencing issues with quota and will
make quota usability more consistent overall.


  Testing

Throughout Pike, our team spent a significant amount of time paying down
testing, technical debt. We cleaned-up and extended support for
federated testing, and we've integrated testing with our tempest plugin.
We added experimental support to test rolling upgrades and look forward
to gating on rolling upgrades in Queens. In the upcoming months, we need
to focus our efforts on better LDAP integration testing, which has been
on our TODO list for too long.


  Team Building

Last, but certainly not least, we need to recruit new keystone
contributors - part or full-time. Some of our most experienced and
well-versed developers moved onto other projects outside of OpenStack.
Luckily, the remaining team members have ambitiously stepped up to fill
the gaps. I want to ensure this project is working optimally on all
cylinders. In order for us to do this and achieve our Queen’s goals, we
need more contributors.


Thanks for reading and I look forward to seeing everyone in Denver,

Lance

As far as I understand the idea of continuous tracing is to collect as few
as possible metrics to get insights of the request (not all tracepoints).
If you keep only API, RPC and Driver calls it is going to
drastically reduce amount of metrics collected.

As well, one of the things that should be done is sending the metrics in
bulk after the request in async way, that way we won't slow down UX and
won't add too much load on underlaying infrastructure.

I'll try to elaborate my points. For monitoring perspective it's going to
be super beneficial to have continuous tracing and I fully support the
effort. However, it won't help community too much to fix the real problems
in architecture (in my opinion it's too late), for example creating VM
performs ~400 DB requests... and yep this is going to be slow, and now
what? how can you fix that?..

A PTG session does make sense.

My main concern is that the driver approach described is a fairly
significant change to the library. I was more confident that it made
sense when it was going to be used for multiple purposes. There may be a
less invasive way to handle secret storage. Or, we might be able to
design a system-level approach for handling those that doesn't require
changing the library at all. So let's not frame the discussion as
"should we add plugins to oslo.config" but "how should we handle secret
values in configuration files".

Re: [openstack-dev] [oslo][oslo.config] Pluggable drivers and protect plaintext secrets

2017-08-04 Thread Fox, Kevin M
I would really like to see secrets separated from config. Always have... They 
are two separate things.

If nothing else, a separate config file so it can be permissioned differently.

This could be combined with k8s secrets/configmaps better too.
Or make it much easier to version config in git and have secrets somewhere else.

Thanks,
Kevin

Subject: [openstack-dev] [oslo][oslo.config] Pluggable drivers and protect 
plaintext secrets

Hi all,

We had a couple of discussions with the Oslo team related to implement 
Pluggable drivers for oslo.config[0] and use those feature to implement support 
to protect plaintext secret on configuration files[1].

In another hand, due the containerized support on OpenStack services, we have a 
community effort to implement a k8s ConfigMap support[2][3], which might make 
us step back and consider how secret management will work, since the config 
data will need to go into the configmap *before* the container is launched.

So, I would like to see what the community think. Should we continue working on 
that pluggable drivers and protect plain text secrets support for oslo.config? 
Makes sense having a PTG session[4] on Oslo to discuss that feature?

Thanks for the feedback in advance.

Re: [openstack-dev] [oslo][performance] Proposing tail-based sampling in OSProfiler

2017-08-04 Thread Rajul Kumar
Hi Vinh

For the `agent idea`, I think it is very good.

However, in OpenStack, that idea may be really hard for us.

The reason is the same with what Boris think.


Thanks. We did a poc and working to integrate it with OSProfiler without
affecting any of the services.
I understand this will be difficult.

For tail-based and adaptive sampling, it is another story.

Exactly. This needs some major changes. We will need this if we look to
have an effective tracing and any kind of automated analysis of the system.

However, in naïve way, we can use sampling abilities from other OpenTracing
compatible tracers

such as Uber Jaeger, Appdash, Zipkin (has an open pull request), LighStep …
by making OSprofiler

compatible with OpenTracing API.

I agree. Initially, this can be done.
However, the limitations of traces they generate is another story and
working to come up with another blueprint on that.

ICYMI, Boris is father of OSprofiler in OpenStack [1]

This is why I was excited to get the first response from him and curious on
his stand. Really looking forward to get more on this from him. Also,
Josh's response on other Tracing thread peeked my curiosity further.

Thanks
Rajul

That's only for 500-599 response codes. The 'broken handling' there literally
means broken as in the server couldn't handle the request. That bullet point is
saying if you had a 500-599 response fixing the code so it's either a 4XX or a
2XX does not need a version. This specific case needs a version boundary because
you going from a 403 -> 204.

The guidelines you linked actually say that this is allowed without a

Monty,


* drop stevedore/plugin support. An OpenStack REST client has no need for
> plugins. All services are welcome. *note below*


Back to 60s style of development? Just copy paste things? no plugins? no
architecture? no libs?

That's not going to work for dozens of OpenStack projects. It's just won't
scale. Every project should maintain plugin for their project. And it
should be enough to say "pip install python-client" that
extend the Core OpenStack python client and adds support of new commands.

The whole core part should be only about how to make plugins interface in
such way that it's easy to extend and provide to end user nice user
experience from both side (shell & python) and nice and stable interface
for client developers .

By the way stevedore is really providing very bad plugin experience and
should not be used definitely.

Boris Pavlovic

[openstack-dev] [cloudkitty] PTL candidacy for Queens

2017-08-04 Thread Christophe Sauthier

Hello everyone,

I would like to announce my candidacy for PTL of Cloudkitty.

During the Pike cycle we have been able continue the openess of our
community but also the addition of some interesting improvment and bug
fixes.

Now with Queen cycle approacing fast, my main focus for cloudkitty will
be to expand the spectrum of interaction : toward more OpenStack 
components

and toward containers.
Finally I would like a special focus with documentation to help to 
adoption

of cloudkitty !

I would also like to take this opportunity to thank all members of the
OpenStack community who helped our team during the lasts cycles.

Thank you,
 Christophe

Also note that this appears to exist:

https://github.com/openstack/python-openstackclient/blob/master/requirements.txt#L10

So even if python-openstacksdk is not a top level project, I would 
assume that it being a requirement would imply that it is? Or perhaps 
neither the python-openstackclient or python-openstacksdk should really 
be used? I've been telling people that python-openstackclient should be 
good to use (I hope that is still correct, though I do have to tell 
people to *not* use python-openstackclient from python itself, and only 
use it from bash/other shell).

I see that there are some maintenance patches getting merged and a pypi

Since it's not in the governance projects list I couldn't determine who the

[openstack-dev] [keystone][api] Backwards incompatible changes based on config

2017-08-04 Thread Lance Bragstad
Keystone had a bug reported [0] recently (that we are targeting to
pike-rc1) that exposes an inconsistency in the API based on
configuration. The happy path is as follows:

- a deployment is configured to store projects (controlled by the
resource backend) and users (controlled by the identity backend) in SQL
- users can have a default project ID and a previous bug [1] fix made it
so users who were associated to a project via their
`default_project_id`, which is an attribute of the user, would be
corrected when that project was deleted
- when a project is deleted (DELETE /v3/projects/{project_id}) a
callback [2] [3] is invoked to unset that project ID from all users who
might have it set as their default project

This works great when both the identity and resource backends are
configured to use SQL. When the identity backend is configured to use
LDAP, the wheels fall off:

- a user attempts to remove a project (DELETE /v3/projects/{project_id})
- the identity callback is invoked and control is passed to the LDAP
identity driver implementation
- the LDAP implementation raises a 403 [4] because read/write LDAP is
not supported in keystone, and unsetting a project ID would classify as
a write operation

Properly fixing this would result in a 403 -> 204 status code, which
requires an API version bump according to the interoperability
guidelines [5] (note that keystone has not implemented microversions at
this point). At the same time - not fixing the issues results in a 403
anytime a project is deleted while in this configuration.

Looking to get some advice from the API WG to see if this is something
we'll be able to address before rc or not. Thanks for reading!

Re: [openstack-dev] [python-openstacksdk] Status of python-openstacksdk project

2017-08-04 Thread Michael Johnson

Awesome Monty. This is a great proposal.  I have no preference on which way 
these merge, but see huge value in straightening this out.  Frankly I think 
some of the tempest plugin work could benefit from having an official and well 
maintained SDK as well.

So, I am in favor of getting the ball rolling here. I was really hoping to be 
able to use this for our dashboard work in Queens, but giving the work here I 
may need to do something in the interim. Maybe if these patches merge for 
python-openstacksdk I can use that for now and migrate as new SDK becomes 
available.

As I mentioned at the top, I'd been thinking some of this already and had 
planned on chatting with folks in person at the PTG, but it seems we're at a 
place where that's potentially counter productive.

Depending on what people think I can follow this up with some governance 
resolutions and more detailed specs.

Thanks!

Re: [openstack-dev] [Cinder] string freeze exception for VMAX driver

2017-08-04 Thread Ian Y. Choi

Hello Sean,

For soft string freezes as a translator's view, trying the way you 
suggested for server projects would be good assuming that:
- The volume of changes (e.g., the number of sentences, ratio of 
changes) needs to be properly limited
- The string change needs to be well notified to translators (e.g., 
sharing to openstack-i18n mailing list)
- It would be so nice if I18n team can keep track of original string 
changes in Zanata - translate.openstack.org but

  currently it is not easy unfortunately.

For hard string freezes, in my honest opinion, it is difficult to change 
the current policy
because some translation sync support activities for a stable branch in 
openstack-infra [1] and

addition of a stable version in translate.openstack.org [2] are dealt.

From those views, I would like to discuss more opinions and would we 
try better approach from the next development cycle

with agreement for server projects?


With many thanks,

/Ian

Hey Ian,

Do you think we should make any changes to our policy for this? Just one thing
that comes to mind, for server projects should we just send out a ML post with
something like "Here is a list of patches we deemed important that had string
translations".

Just thinking of how we can keep things moving when needed while still making
sure important things are communicated well.

Or is that even too much? During soft string freeze, should the server project
core teams just try to be more aware of these but just approve patches that
are important fixes and move on?

Thanks,
Sean

Concerns


I share the same concerns Thierry listed above. Specifically:

* It is not an official project, but its name leads people to believe 
it's the "right" thing to use if they want to talk to OpenStack clouds 
using Python.


* The core team is small to begin with, but recently got hit in a major 
way by shifts in company priorities.


I think we can all agree that those are concerns.

Three additional points:

* The OpenStack AppDev group and the various appdev hackathons use 
shade, not openstacksdk. This is what we have people out in the world 
recommending people use when they write code that consumes OpenStack 
APIs. The Interop challenges at the Summits so far have all used 
Ansible's OpenStack modules, which are based on shade, because they were 
the thing that works.


* Both shade and python-openstackclient have investigated using 
openstacksdk as their REST layer but were unable to because it puts some 
abstractions in layers that make it impossible to do some of the 
advanced things we need.


* openstacksdk has internal implementations of things that exist at 
different points in the stack. We just added full support for version 
service and version discovery to keystoneauth, but openstacksdk has its 
own layer for that so it both can't use the ksa implementation and is 
not compliant with the API-WG consume guidelines.


It's not all bad! There is some **great** work in openstacksdk and it's 
a shame there are some things that make it hard to consume. Brian, 
Qiming and Terry have done a bunch of excellent work - and I'd like to 
not lose it to the dustbin of corporate shifting interest.


**warning** - there is a very large text wall that follows. If you don't 
care a ton on this topic, please stop reading now, otherwise you  might

Proposal


I'd propose we have the shade team adopt the python-openstacksdk codebase.

This is obviously an aggressive suggestion and essentially represents a 
takeover of a project. We don't have the luxury of humans to work on 
things that we once had, so I think as a community we should be 
realistic about the benefits of consolidation and the downside to 
continuing to have 2 different python SDKs.


Doing that implies the following:

* Rework the underlying guts of openstacksdk to make it possible to 
replace shade's REST layer with openstacksdk. openstacksdk still doesn't 
have a 1.0 release, so we can break the few things we'll need to break.


* Update the shade mission to indicate its purpose in life isn't just 
hiding deployer differences but rather is to provide a holistic 
cloud-centric (rather than service-centric) end-user API library.


* Merge the two repos and retire one of them. Specifics on the mechanics 
of this below, but this will either result in moving the resource and 
service layer in openstacksdk into shade and adding appropriate 
attributes to the shade.OpenStackCloud object, or moving the 
shade.OpenStackCloud into something like openstack.cloud and making a 
shade backwards-compate shim. I lean towards the first, as we've been 
telling devs "use shade to talk to OpenStack" at hackathons and 
bootcamps and I'd rather avoid the messaging shift. However, pointing to

[openstack-dev] [tripleo] CI Squad Meeting Summary (week 31)

2017-08-04 Thread Attila Darazs
If the topics below interest you and you want to contribute to the 
discussion, feel free to join the next meeting:


Time: Thursdays, 14:30-15:30 UTC
Place: https://bluejeans.com/4113567798/

Full minutes: https://etherpad.openstack.org/p/tripleo-ci-squad-meeting

There are a lot of people on vacation, so this was a small meeting.

We started by discussing the hash promotions and the ways to track 
issues. Whether it's an upstream or RDO promotion issue, just create a 
Launchpad bug against tripleo and tag it with ci and alert. It will 
automatically gets escalated and gets attention.


Gabriele gave a presentation about his current status with container 
building on RDO Cloud. It looks to be in a good shape, however there are 
still bugs to iron out.


Arx explained that the scenario001 jobs are now running a tempest test 
as well, good way to introduce more testing upstream, while Emilien 
explained that we should probably do more tempest testing on container 
jobs as well.


Wes brought up an issue about collecting logs during the image building 
process which needs attention.


That's it for this week, have a nice weekend.

Best regards,
Attila

Re: [openstack-dev] [Cinder] string freeze exception for VMAX driver

2017-08-04 Thread Ian Y. Choi

Hello Helen,

Thanks a lot for sharing a string freeze exception request to 
openstack-dev mailing list.


With @amotoki's comment [1] and the discussion on the last IRC meeting 
yesterday [2],
I18n team is fine and there will be no problem to accept the requests 
from I18n team's perspective.


Note that String Freeze has been important for Docs & I18n team to 
acknowledge string freeze
status and take appropriate actions of what needs to be changed to 
documentation and translation activities if needed.
Since I18n team now more focuses on dashboard translations [1] and 
documents are being migrated [3],
I think the importance of string freeze for server projects (e.g., 
cinder, nova, keystone, neutron) might
be less important than previous cycle(s), but sharing the status to all 
the teams including release management team

is a good idea to stay on the same page as much as possible :)


With many thanks,

/Ian, I18n team Ocata PTL.

[openstack-dev] [cinder][stable] Reverting the deprecation notice: Cinder Driver for NetApp E-Series

2017-08-04 Thread Ravi, Goutham
Developers and Operators,

NetApp had prior provided notification [1] in accordance with community policy 
[2] of an intention to deprecate the iSCSI and FC Cinder drivers for NetApp 
E/EF-Series systems [3].  The community notification issued had the effect of 
introducing us to and engendering discussion with deployers (and those with 
near term plans to become deployers) indicating the importance of continued 
support for E/EF-series systems beyond the Pike release.   We hadn’t been prior 
familiar with many of these folks and greatly appreciate their having shared 
their perspective.

We’re pleased to announce that we’ve reconsidered our approach based on this 
new information.

Our intention with this mail is to revoke [3] the deprecation notice indicated 
in April 2017 and to continue to support E/EF-series systems.  As such, we do 
not intend to remove these drivers during the Queens or for the foreseeable 
future.

Any Cinder E-series current or prospective deployers are encouraged to get in 
touch with NetApp via the community #openstack-netapp IRC channel on freenode 
or via the #OpenStack Slack channel on http://netapp.io for 
any questions.

Thanks,
Goutham Pacha Ravi

[openstack-dev] [docs][ptl] Candidacy for Docs

2017-08-04 Thread Petr Kovar
Hi all,

I'd like to announce my candidacy for PTL of the docs project for Queens.

I've been active in various open source documentation and
translation projects since 2007 and started contributing to OpenStack
docs during the Mitaka cycle, both upstream and in the RDO Project.

The docs project has recently seen a significant decrease in both the
number of submitted updates and contributors, but thanks to a group of
dedicated people in the community, we've managed to come up with a clear
plan to migrate docs over to individual projects, restructure them and
reduce the scope to keep them maintainable. This is now well underway and
I'd like to help the team and the community drive and continue with this
work.

In docs, we generally like to keep it rather short and simple, so let me
summarize the main three points as follows:

Support and help drive the remaining tasks in restructuring and/or moving
content from the core docs suite.

Help establish the docs team as content editors for individual project docs
when needed or requested.

Stay open and friendly to new contributors, no matter if they are
prospective core members or drive-by docs contributors, with the
understanding that docs are a great way to get involved in the project for
both the non- and developers.

Thank you,
pk

2017-08-04 Thread Matt Riedemann

On 8/4/2017 8:41 AM, Tom Kennedy wrote:
Is there an Openstack document that shows how to extend openstack to do 
something like this?


The create snapshot API is this in upstream Nova:

https://developer.openstack.org/api-ref/compute/#create-image-createimage-action

There is no distinction between a live and cold snapshot in the end user 
REST API. That's dependent on the backend compute driver. For example, 
the libvirt driver may attempt to perform a live snapshot if possible, 
but falls back to a cold snapshot if that's not possible. Other drivers 
could do the same.


As for the difference between the OpenStack concept of a snapshot and 
the VMware concept of a snapshot, I don't know what that is, but I can 
saw we wouldn't add a VMware-specific REST API for snapshots to the 
compute API when we already have the createImage API. So some design 
work would be involved if you wanted to upstream this.


For information on contributing features to Nova, you can start here:

[openstack-dev] [magnum] PTL Candidacy for Queens

2017-08-04 Thread Spyros Trigazis
Hello!

I would like to nominate myself as PTL for the Magnum project for the
Queens cycle.

I have been consistently contributing to Magnum since February 2016
and I am a core reviewer since August 2016. Since then, I have
contributed to significant features like cluster drivers, add Magnum
tests to Rally (I'm core reviewer to rally to help the rally team with
Magnum related reviews), wrote Magnum's installation tutorial and
served as docs liaison for the project. My latest contribution is the
swarm-mode cluster driver. I have been the release liaison for Magnum
for Pike and I have contributed a lot in Magnum's CI jobs (adding
multi-node, DIB and new driver jobs, I haven't managed to add Magnum
in CentOS CI yet :( but we have granted access). Finally, I have been
working closely with other projects consumed by Magnum like Heat and
Fedora Atomic.

My plans for Queens are to contribute and guide other contributors to:
* Finalize and stabilize the very much wanted feature for cluster
  upgrades.
* Add functionality to heal clusters from a failed state.
* Add functionality for federated Kubernetes clusters and potentially
  other cluster types.
* Add Kuryr as a network driver.

Thanks for considering me,
Spyros Trigazis

That is correct.  This is for the IBM ICMO product. 
Here is the only reference I see in the IBM documentation regarding this.
https://www.ibm.com/support/knowledgecenter/SST55W_4.3.0/liaca/liaca_cfg_snapshot.html

Is there an Openstack document that shows how to extend openstack to do 
something like this?

I think you're looking at some forked code because that doesn't exist in 
upstream Nova:

https://github.com/openstack/nova/tree/master/nova/api/openstack/compute

I seem to remember a team in China at IBM working on VMware snapshots 
years ago, or something like this, for a product, so maybe you stumbled 
upon that.

Re: [openstack-dev] [oslo][performance] Proposing tail-based sampling in OSProfiler

2017-08-04 Thread Ilya Shakhat
Hi,

Continuous tracing is a cool story, but before proceeding it would be good
to estimate the overhead. There will be an additional delay introduced by
OSProfiler library itself and delay caused by events transfer to consumer.
OSProfiler overhead is critical to minimize. E.g. VM creation produces >1k
events, which gives almost 2 times performance penalty in DevStack. Would
be definitely nice to have the same test run on real environment --
something that Performance Team could help with.

Transfer part of delay can be reduced by e.g. writing events to local file
and then processing them with Logstash + Grok. Agent-based approach is good
for more real-time processing -- can we consider to use Logstash UDP [1]
input or Elastic Beat [2] framework? OSProfiler has drivers support (works
in Pike!) and we can give operators freedom to choose the pipeline they
prefer.

[2]
https://www.elastic.co/guide/en/beats/libbeat/current/beats-reference.html

[openstack-dev] [tc] Technical Committee Status update, August 4th

2017-08-04 Thread Thierry Carrez
Hi!

This is the weekly update on Technical Committee initiatives. You can
find the full list of all open topics at:

https://wiki.openstack.org/wiki/Meetings/TechnicalCommittee


== Recently-approved changes ==

* Pike goals updates: nova, cinder
* New repositories: publiccloud-wg, oswin-tempest-plugin

Not much TC activity this week as we past Pike Feature Freeze and
everyone is focused on producing Pike release candidates.


== Stuck tags ==

We have a number of non-straightforward tag additions in the queue,
which need a bit more input before they can proceed:

Kolla's stable:follows-policy application [1] has been proposed July
2016 but was delayed for various reasons. Currently stuck near the goal
line waiting on some last-minute commitment. Would be great to merge it
before Pike release so that it can be included in the project navigator.

Nova and Ironic's assert:supports-api-interoperability addition[2] is
missing their respective PTL support for them. It also triggered an
interesting side discussion on the value of tags in general and this tag
in particular. This one will likely be abandoned unless it gets the PTL
support on them.

Trove's status:maintenance-mode addition[3] is WIP until Queens opens.
One question is whether Trove is now past the low point, and setting the
tag would convey the wrong message for a recovering project. Please join
the discussion if you have an opinion.

[1] https://review.openstack.org/346455
[2] https://review.openstack.org/#/c/482759/1
[3] https://review.openstack.org/#/c/488947/


== Open discussions ==

Flavio's resolution about allowing teams to host meetings in their own
IRC channels is still in the early days of discussion, and is likely to
need a few iterations to iron out. Please join the first round of reviews:

https://review.openstack.org/485117

Discussion on John's resolution on how decisions should be globally
inclusive is entering the final stages. Please review it if you haven't yet:

https://review.openstack.org/#/c/460946/


== Voting in progress ==

The description of what upstream support is still missing a few votes to
pass. Please review it now:

https://review.openstack.org/440601


== TC member actions for the coming week(s) ==

Flavio still needs to incorporate feedback in the "Drop TC meetings"
proposal and produce a new patchset, or abandon it since we pretty much
already implemented the described change.


== Need for a TC meeting next Tuesday ==

Currently-proposed changes are lacking reviews more than they are stuck,
so I don't think we need a synchronous TC meeting next week. Let me know
if you'd like to have one and the topic you would like to see discussed.


Cheers!

[openstack-dev] [Blazar] PTL Candidacy for Queens

2017-08-04 Thread Masahito MUROI

Dear everyone,

I'd like to announce my candidacy as Blazar PTL for the Queens release 
cycle.


I served as PTL for the Blazar project during Pike cycle. And I would 
like to continue to do in the next cycle.


During the Pike cycle, the Blazar team made tons of progress for 
resolving feedback by operators as well as implementing the Blazar 
features and bug fixes.  The team has made v1 API more manageable for 
users, implemented Horizon plugin and the instance reservation support. 
The big improvement was supported by the development cycle between 
operators and developers.


In the Queens cycle I'd like to focus on the following things:

- Blazar's Features: improving resiliency and user experience

The Blazar started to support 2 types of reservation, host reservation 
and instance reservation, from Pike release.  The two reservation 
features are motivated by real users. In the real deployment, resiliency 
is one of key points for the reservation service.


Additionally, the team mainly focused on server-side developments during 
the last two cycle. The development made the blazar server and its 
features stable. So it's good time to improve the user experience of the 
stable feature in the next cycle.


- Community: Encouraging the team to be more diverse

The team's activities in the Pike cycle become 1.5 times bigger than the 
Ocata cycle. Beside the big growth, most of the activities were done by 
the team members who revived the project since the Barcelona Summit.


Different perspectives from people who have different backgrounds and 
demands make good developments in the next or later release. So I'd like 
to encourage more people to join this team.



best regards,
Masahito

Hi Tony,

And sorry for the additional effort and confusion. The bump should have

Thanks for raising this.

Beyond its limited activity, another issue is that it's not an official
project while its name make it a "default choice" for a lot of users
(hard to blame them for thinking that
http://git.openstack.org/cgit/openstack/python-openstacksdk is not the
official Python SDK for OpenStack, but I digress). So I agree that the
situation should be clarified.

I know that Monty has pretty strong feelings about this too, so I'll
wait for him to comment.

Re: [openstack-dev] [tripleo] Facilitating automation testing in TripleO UI

About 10 years ago, we were promised a fully semantic version of HTML.
No more nested divs to structure your documents.  However, all we got
was a few generic, and only marginally useful elements like  and
.

While this is useful for addressing a particular element, I think it
would still require quite a bit of parsing.  You'd find yourself writing
string-splitting code all over the place.  It would make the code harder
to read without providing much semantic information --- unless of course
every single element had some kind of ID.

I like this option the best.  It seems to be the most natural way of
adding semantic information to the bare-bones building blocks of the
web.  Classes are simple strings that add information about the intended
use of the element.  Using jQuery-like selectors, this can make for some
easy-to-understand code.  Do you want to grab the power state of the
currently expanded node in the list?

$('#node-list div.node.expanded').find('.power-state')

By default, Selenium can query the DOM by id, by class name, and by
xpath.  It can be extended to use pyquery which is the Python
implementation of the jQuery css selector.  I think many of the
automation implementation headaches can be solved by using pyquery.

https://blogs.gnome.org/danni/2012/11/19/extending-selenium-with-jquery/

Furthermore, I think that classes can be used effectively when
describing transient state like the expanded/collapsed state of a
togglable element.  It's easy to implement on the client side, and it
should be helpful on the automation side.

Relying on patternfly presentational class names won't suffice.

This seems pretty drastic.  I wonder if there is a way we could extend

[openstack-dev] [Elections] Candidacy for Senlin PTL (Queens)

2017-08-04 Thread YUAN RUIJIE
Hi all,

I'd like to announce my candidacy as Senlin PTL in Queens cycle.

I began to contribute to Senlin project since 2016.05 and joined the
team as a core reviewer in Ocata cycle. It is my pleasure to work
with the great team to make this project better and better, and we
will keep moving and look forward to push Senlin to the next level.

In past cycles, we have done a lot of great works. As a clustering
service, we already can handle some resource types like nova
server, heat stack .etc. What's more, we already have some small
steps for supporting NFV & k8s use cases.

In next cycle, which is Queens, I'd like to focus on the tasks as follows:

- Improve runtime data processing inside Senlin server
- Improved AZ & Region placement policy
- Improved health policy to provide HA support
- A better support to NFV use cases
- Add support to k8s use cases
- A stronger team to push Senlin to next level

These are the tasks that I believe I can help. All ideas are welcomed.

Sincerely,
Ruijie Yuan (ruijie)
