[oslo][oslo-messaging][nova] Stein nova-api AMQP issue running under uWSGI
by iain.macdonnell＠oracle.com 08 May '19

08 May '19

Is anyone running Stein nova-api under uWSGI? I'm trying to do this, in exactly the same way as I did with Rocky, but encountering a new problem... The symptom is intermittent failure of API operations that involve RPC calls - notably getting the noVNC console URL for an instance. The nova-api log shows RPC timeouts and "connection reset by peer" for AMQP. I've ruled out environmental issues, as a Rocky installation on the same hosts works fine. With oslo debug enabled, I see that the first API call causes a AMQP connections to be established, and the RPC call gets its reply, and all is well... but there are no heartbeats logged after that. 3 minutes later, rabbitmq-server reports that it has received no heartbeats, and drops the connection. On a subsequent API call (but not before), nova-api logging "connection reset by peer" and the RPC call times out. With the Rocky code, once the first API call causes the AMQP connections to be established, regular heartbeats start happening, the connections are maintained, and subsequent API calls work as expected. It seems like a lockup in a thread that's supposed to maintain the AMQP connection, or something. I tried to use SIGUSR2 to trigger guru meditation, but it seems that uWSGI has its own interpretation of SIGUSR2, so nova-api never sees it (anyone know a way around this?). Running nova-api as a standalone service, instead of under uWSGI, the problem does not occur (I see the heartbeats, and everything works fine). I've tried updating oslo-messaging (and python-amqp) on a Rocky installation to the Stein version, but the problem does not reproduce. Ideas? ~iain

Hi all Here's the etherpad for Heat in Denver Summit and PTG: https://etherpad.openstack.org/p/DEN-Train-Heat I will update heat project onboarding video to slide page later, at meanwhile, enjoy slides for onboarding: https://goo.gl/eZ3bbH and project update: https://goo.gl/Fr6rBH *Some target items for Train cycle:* - Move to service token auth for re-auth - Hide OS::Glance::Image and mark as placeholder resource - make placeholder designate V1 resources too since they already deleted in Designate in Rocky - Heat zombie services entries recycle - Atomic ExtraRoute resource improvement - Better document and scenario test support for Auto-scaling SIG and Self-healing SIG - Ironic resources (Don't get this wrong, Heat already support Ironic by using Nova server resources. This is about directly supported Ironic resources) - Adding support for Heat in Terraform For some ongoing tasks like Vitrage Template still on our review target list too, and we will try to make sure those works for features/deprecation tasks will be landed soon as we can. *Help most needed for Heat:* We very much need for core reviewers to help to push patches in. So, please join us for help to review an develop. I hope we can still keep Heat develop more active.

[all|requirements|stable] update django 1.x to 1.11.20
by Dirk Müller 07 May '19

07 May '19

Hi, a number of security issues have been fixed for django 1.11.x which is still used by horizon for python 2.x and also optionally for python 3.x. The horizon gate jobs are already using that version: http://logs.openstack.org/46/651546/1/check/horizon-openstack-tox-python3-d… as they install django without using constraints.txt . Any objections to updating the global requirements constraints to match that? Reviewing the django fixes on the 1.11.x closely only shows security and data corruption bugfixes, so it should be pretty good on the risk/benefit trade-off. Thanks, Dirk

[octavia][taskflow] Adaption of persistence/jobboard (taskflow expert review needed)
by Anna Taraday 07 May '19

07 May '19

Hello everyone! I was looking at the topic of usage taskflow persistence and jobboard in Octavia [1]. I created a simple PoC to check what should be done to enable this functionality [2] . >From what I see, taskflow expects that data, which will be stored in persitence backend/jobboard backend, is a dict or an object easily converted to dicts [3] (error [3.1]) Also functions that creates flow should be importable [4] (error [4.1]). These two points lead to refactor required for Octavia to enable taskflow persistence and jobboard: 1) Convert data which is passed between flows in dicts, at this moment it is db objects with links to other db objects. 2) Create importable flow functions. As far as I see the only OpenStack project which adapted taskflow persistence is poppy [5] I'm looking for taskflow expect to take a look at all this and give some comments - whether I am correct or missing something. Thank you for your time in advance!
