bindep, pacman, and PyPI release
by Jakob Lykke Andersen 06 Feb '21

06 Feb '21

Dear developers, I'm trying to use bindep on Arch but hitting a problem with the output handling. It seems that 'pacman -Q' may output warning lines if you have a file with the same name as the package. E.g.,: $ mkdir cmake $ pacman -Q cmake error: package 'cmake' was not found warning: 'cmake' is a file, you might want to use -p/--file. The current detection assumes the "was not found" is the last part of the output. Applying the patch below seems to fix it. After applying this patch, or whichever change you deem reasonable to fix the issue, it would be great if you could make a new release on PyPI. Thanks, Jakob diff --git a/bindep/depends.py b/bindep/depends.py index bb9553f..cacc863 100644 --- a/bindep/depends.py +++ b/bindep/depends.py @@ -558,7 +558,8 @@ class Pacman(Platform): stderr=subprocess.STDOUT).decode(getpreferredencoding(False)) except subprocess.CalledProcessError as e: eoutput = e.output.decode(getpreferredencoding(False)) - if e.returncode == 1 and eoutput.strip().endswith('was not found'): + s = "error: package '{}' was not found".format(pkg_name) + if e.returncode == 1 and s in eoutput: return None raise # output looks like

[oslo][keystone] Future of oslo.limit
by Ben Nemec 06 Feb '21

06 Feb '21

Hi, Last week in the Oslo meeting it was noted that we have some rather old patches open against oslo.limit. Before we spend a bunch of time getting those reviewed and merged, we wanted to confirm that this was still something people wanted to pursue. Things have been pretty quiet on the limit front for a while now, and doing the Oslo side does us no good if no one is going to consume it. I realize this is something of a chicken-and-egg situation since the library was somewhat blocked on [0], but that's been ready to merge for months and so far has only one review. If we do want to continue, merging that would be the first step. Then we should look at [1] which was the patch that prompted this conversation. Thanks. -Ben 0: https://review.opendev.org/c/openstack/oslo.limit/+/733881 1: https://review.opendev.org/c/openstack/oslo.limit/+/695527

[all][mentoring][outreachy][GSoC]Summer Interns/ Student Coders Anyone?
by Kendall Nelson 05 Feb '21

05 Feb '21

Hello :) So, if you've been involved in Outreachy, the Google Summer of Code[1] is pretty similar. It looks like the applications for projects open January 29, 2021 at 11:00 (Pacific Standard Time) if anyone wants to apply. I encourage you all to do so! It gets a lot of attention from university students so it's a great opportunity to get some new contributors and teach some more of the world about our community and open source! If you are interested in applying, let me know and I will do what I can to help you with the application to get it done on time (deadline not listed on the site yet, but they always come faster than we'd like)! -Kendall (diablo_rojo) [1] https://summerofcode.withgoogle.com/get-started/

[ironic] Node wont boot from virtual media
by Derek Higgins 05 Feb '21

05 Feb '21

Hi, I've been trying to get virtual media booting to work on a ProLiant DL380 Gen10 but not having any luck. Over redfish Ironic attaches the media, sets the Next boot option to 'cd' and then restarts the node. But it continues to boot from the HD as if the vmedia is being ignored. I'm wondering if anybody has seen anything similar, I'm thinking perhaps I don't have a bios setting configured that I need? I have the same problem if I set the One time boot on the iLo dashboard. System ROM U30 v2.40 (10/26/2020) iLO Firmware Version 2.33 Dec 09 2020 On another ProLiant DL380 Gen10 with the same ROM and iLo version where this works. Some of the hardware is different, in particular the one that works has a "HPE Smart Array P408i-a SR Gen10 " but the one that doesn't has a "HPE Smart Array E208i-a SR Gen10" could this be the relevant difference? any ideas would be great, thanks, Derek.

[All][StoryBoard] Angular.js Alternatives
by Kendall Nelson 05 Feb '21

05 Feb '21

Hello Everyone! The StoryBoard team is looking at alternatives to Angular.js since its going end of life. After some research, we've boiled all the options down to two possibilities: Vue.js or React.js I am diving more deeply into researching those two options this week, but any opinions or feedback on your experiences with either of them would be helpful! Here is the etherpad with our research so far[3]. Feel free to add opinions there or in response to this thread! -Kendall Nelson (diablo_rojo) & The StoryBoard Team [1] https://vuejs.org/ [2] https://reactjs.org/ [3] https://etherpad.opendev.org/p/replace-angularjs-storyboard-research

[neutron][victoria] Front / Back Routers
by DHilsbos＠performair.com 05 Feb '21

05 Feb '21

All; My team and I have been working through the tutorials on Server World (server-world.com/ean/) in order to learn and build an OpenStack cluster. We've also been looking at the official documentation to attempt to increase our knowledge of the subject. I have a question about Neutron though. All the examples that I remember have Neutron setup with a single router. The router is part of a "provider" network, and subnet on the outside, and one or more "tenant" networks on the inside. Floating IPS, then appear to be IP addresses belonging to the "provider" subnet, that are applied to the router, and which the router then NATs. These setups look like this: Physrouter1 (physical router) subnet: 192.168.0.0/24, IP address: 192.168.0.1 | Physnet1 (192.168.0.0/24)(ovs network definition) | Router1 (ovs router)(allocation pool: 192.168.0.100 - 192.168.0.254) <-- Floating IPs are "owned" by this, and are in the range of the allocation pool | Tenant network(s) This has the advantage of being easy, fast, secure, and simple to setup. What if you wanted something where you could route whole subnet into your OpenStack cluster. Physrouter1 (physical router) subnet: 172.16.255.0/24, IP address: 172.16.255.1 | Physnet1 (172.16.255.0/24)(ovs network definition) | Router1 (ovs router)(fixed IP addresses: 172.16.255.2 & 172.16.254.1/24 + static / dynamic routing) | Network (17216.254.0/24) | Router2(ovs router)(allocation pool: 172.16.254.5 - 172.16.254.254) <-- Floating IPs are "owned" by this, and are in the range of the allocation pool | Tenant network(s) Is my understanding accurate? Are there advantages of one over the other? What commands are used to specify static IPs for ovs routers, and static routing rules? Thank you, Dominic L.

[ops][largescale-sig] How many compute nodes in a single cluster ?
by Thierry Carrez 05 Feb '21

05 Feb '21

Hi everyone, As part of the Large Scale SIG[1] activities, I'd like to quickly poll our community on the following question: How many compute nodes do you feel comfortable fitting in a single-cluster deployment of OpenStack, before you need to scale it out to multiple regions/cells/.. ? Obviously this depends on a lot of deployment-dependent factors (type of activity, choice of networking...) so don't overthink it: a rough number is fine :) [1] https://wiki.openstack.org/wiki/Large_Scale_SIG Thanks in advance, -- Thierry Carrez (ttx)
