[dev][taskflow] Accepting any decision
by Jiří Rája 07 Oct '19

07 Oct '19

Hi, I wrote the code in the attachment and I would like to ask if it's possible to execute next task (step3) even if one decider returns True (link from step 1 to step 3) and one returns False (link from step 2 to step 3). If it is possible could someone alter the code? Or is there any other way to do it? And if the task wouldn't have to wait for all of the links, it would be great. Thank you! All the best, Rája

[neutron]: Latest Queens release: dhcp-client takes too long processing messages and falls behind.
by fsbiz＠yahoo.com 07 Oct '19

07 Oct '19

Hi neutron team, We've been troubleshooting an issue with neutron's dhcp-client for sometime now. We were previously on neutron 12.0.5 and observed that upon reloading 5-8 baremetals simultaneously almost always led to a few baremetals failing PXE boot during provisioning and/or cleaning. This was traced to afixed bug. https://bugs.launchpad.net/neutron/+bug/1760047 which was applied to Queens in April 2019. https://review.opendev.org/#/c/649580/ We patched the above fix but found out the problem was not resolved. The fix gets rid of the semaphores by serializing the multiple messages into aPriority Queue. The Priority Queue then drains the messages serially one by one making sure notto yield during the processing of each message. All in all this just seems like a more elegant way ofgetting rid of the semaphores but does not really fix the issue at hand. Below are the logs from dhcp-agent in neutron release 12.0.5. As can be seen the semaphore locks all threads for almost 6 seconds.While the below has been fixed using https://review.opendev.org/#/c/649580/ the underlying problem has not been fixed. The semaphore has been removed but instead the message is being serialized and does not yieldresulting in PXE boot failures on the baremetal nodes. Any pointers would be appreciated. thanks,Fred 2019-10-03 18:07:37.454 318956DEBUG oslo_concurrency.lockutils [req-eac79995-3846-46e6-b946-c5b5ccdb7aa58941137e383548bda725e74a93b2f865 19f6fb7446dc47dd88c63cf03c1cce94 -

[all][requirements] requirements branched train - cycle-trailing are on notice that master is now ussuri
by Matthew Thode 07 Oct '19

07 Oct '19

Just a friendly ping that the train keeps rolling. Master is now ussuri. https://releases.openstack.org/constraints/upper/ussuri should work soon for those that want to switch their install_command in tox.ini within master earlier in the cycle (rather than having things pile up). I'll email again once it's working. cycle-trailing projects are on notice that if they track master, the dependencies may change from what they are currently working on (train). If you have any questions please let me know (in the #openstack-requirements channel preferably). P.S. FFE season is over -- Matthew Thode

[all][tc][ptl] "Meet the project leaders" opportunities in Shanghai
by Thierry Carrez 07 Oct '19

07 Oct '19

Hi everyone, The summit is going to mainland China for the first time. It's a great opportunity to meet the Chinese community, make ourselves available for direct discussion, and on-board new team members. In order to facilitate that, the TC has been suggesting that the Foundation organizes two opportunities to "meet the project leaders" during the Summit in Shanghai: one around the Monday evening marketplace mixer, and one around the Wednesday lunch: https://www.openstack.org/summit/shanghai-2019/summit-schedule/events/24417/ https://www.openstack.org/summit/shanghai-2019/summit-schedule/events/24426… OpenStack PTLs, TC members, core reviewers, UC members interested in meeting the local community are all welcome. We'll also have leaders from the other OSF-supported projects around. See you there! -- Thierry Carrez (ttx)

[oslo] FFE: Support "qemu-img info" virtual size in QEMU 4.1 and late
by Herve Beraud 07 Oct '19

Hi, I request a late feature freeze exception (FFE) for https://review.opendev.org/#/c/686598/ and https://github.com/openstack/oslo.utils/commit/89bccdee95f81ddb54b427d6af17… -- "Support "qemu-img info" virtual size in QEMU 4.1 and later". It will fix an issue that can be blocking for users so it's can be really valuable for operators, if we release it ASAP. They would be delighted if it were included in Train. Please let me know if you have any concerns or questions. Thank you for your consideration.

[cloudkitty] 07/10 IRC meeting recap
by Luka Peschke 07 Oct '19

07 Oct '19

Hello everybody, This is the recap for today's IRC meeting of the cloudkitty team. The agenda can be found at [1] and the logs can be found at [2]. cloudkitty 11.0.0 and python-cloudkittyclient 3.1.0 =================================================== Cloudkitty 11.0.0 has been released on september 25th. If no critical bug is reported, it will be final release for the train cycle. The release notes for the train cycle can be found at [3]. New meeting schedule ==================== As discussed, the cloudkitty IRC meeting will now happen on the 1st and 3rd monday of each month at 14h00 UTC. This time has been chosen because cloudkitty's main contributors are split between montreal and france. Of course, if anyone from an incompatible timezone would like to take part in the meetings, we can re-adjust the schedule. From now on, we'll provide a recap to the ML after each meeting. New features / specs / projects =============================== First, I'd like to welcome our two new contributors, Quentin Anglade (qanglade) and Julien Pinchelimouroux (julien-pinchelim). Quentin has been working on porting some v1 API endpoints to v2, more specifically the ones used for rating module configuration (/v1/rating/modules). These endpoints will be included in the Ussuri version. Julien is working on a standalone dashboard for cloudkitty. It will be compatible with the standalone mode, but will also support keystone integration. It should provide a more modern and easier to use interface than the cloudkitty-dashboard horizon plugin. It will require the v2 API to work. I've been busy with some improvements to v2 API performance, in particular regarding driver loading. The spec can be found at [4]. Tempest plugin ============== Justin (jferrieu) has been working on the tempest plugin. Now that the Elasticsearch v2 storage driver is supported in devstack, we plan to add a lot more tests and some complete scenarios. Some of Justin's work on differenciating v1 and v2 API tempest tests can be found at [5]. The next meeting will happen on October 21st at 14h00 UTC. Cheers, -- Luka Peschke (peschk_l) [1] https://etherpad.openstack.org/p/cloudkitty-meeting-topics [2] http://eavesdrop.openstack.org/meetings/cloudkitty/2019/cloudkitty.2019-10-… [3] https://docs.openstack.org/releasenotes/cloudkitty/train.html [4] https://review.opendev.org/#/c/686391/ [5] https://review.opendev.org/#/c/686210/
