| 07:34:25 | bauzas | hmmm, can't find a castellanclient kind of thing | |
| 07:34:40 | gibi | bauzas: does castellan just an interface and by having castellen we don't have to pull in whole key manager backend like barbican | |
| 07:34:43 | gibi | ? | |
| 07:35:02 | bauzas | I'm not a specialist of any OpenStack key manager | |
| 07:35:16 | bauzas | but if you're right, that explains my readings | |
| 07:36:02 | bauzas | mmmm https://docs.openstack.org/castellan/latest/user/index.html#basic-usage | |
| 07:36:07 | bauzas | looks you're right indeed | |
| 08:41:06 | stephenfin | bauzas, gibi: The fix for that o.vo version issue is here, btw https://review.opendev.org/#/c/742650/1 | |
| 08:41:16 | gibi | stephenfin: thanks | |
| 08:42:09 | stephenfin | alex_xu: As gibi said, I don't think anyone noted any upgrade issues with provider.yaml. Perhaps you're confusing it with the investigation of upgrade issues bauzas was doing for the vTPM series? | |
| 08:43:24 | gibi | stephenfin: ahh, that was the upgrade discussion yesterday ^^ | |
| 08:43:42 | gibi | I knew there was something | |
| 08:43:49 | gibi | I just did not remember what | |
| 08:45:14 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Use compression by default for 'SshDriver' https://review.opendev.org/684393 | |
| 08:46:16 | alex_xu | stephenfin: ah, thanks :) | |
| 09:23:55 | openstackgerrit | Merged openstack/nova master: scheduler: Request vTPM trait based on flavor or image https://review.opendev.org/739210 | |
| 09:24:03 | openstackgerrit | Merged openstack/nova master: crypto: Add support for creating, destroying vTPM secrets https://review.opendev.org/739211 | |
| 09:24:16 | openstackgerrit | Merged openstack/nova master: manager: Prevent compute startup on invalid vTPM config https://review.opendev.org/739212 | |
| 09:24:27 | openstackgerrit | Merged openstack/nova master: tests: Rename tests for '_create_guest_with_network' https://review.opendev.org/740464 | |
| 09:24:37 | openstackgerrit | Merged openstack/nova master: tests: Move single use constants to their callers https://review.opendev.org/741280 | |
| 09:24:46 | openstackgerrit | Merged openstack/nova master: tests: Define constants in '_IntegratedTestBase' https://review.opendev.org/741281 | |

| 09:25:02 | openstackgerrit | Merged openstack/nova master: tests: Add 'PlacementHelperMixin', 'PlacementInstanceHelperMixin' https://review.opendev.org/741283 | |
| 09:25:13 | openstackgerrit | Merged openstack/nova master: tests: Make '_IntegratedTestBase' subclass 'PlacementInstanceHelperMixin' https://review.opendev.org/741284 | |
| 09:31:04 | stephenfin | Holy s***, they all merged in one go. No CI failures :O | |
| 09:31:11 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Use compression by default for 'SshDriver' https://review.opendev.org/684393 | |
| 09:31:54 | gibi | stephenfin: that was a nice set | |
| 09:31:58 | stephenfin | bauzas, gibi: Can you look at ^ again real quick? Turns out 'scp' cares about the order of arguments. CI caught it for us and will catch it again if it's wrong | |
| 09:32:10 | gibi | stephenfin: looking | |
| 09:32:10 | stephenfin | (from https://zuul.opendev.org/t/openstack/build/7e8c6c6ddaba44e09a90a847dfe6ee46/log/logs/screen-n-cpu.txt) | |
| 09:32:14 | stephenfin | Thanks | |
| 09:32:14 | bauzas | ack | |
| 09:32:49 | stephenfin | It did | |
| 09:33:05 | bauzas | hah | |
| 09:33:09 | bauzas | fwiw https://linux.die.net/man/1/scp | |
| 09:33:32 | stephenfin | I just thought it was intermittent failures and wasn't looking at it often enough to spot the trend :) | |
| 09:33:39 | stephenfin | zuul++ | |
| 09:34:04 | bauzas | stephenfin: i don't see any required ordering with scp manpage | |
| 09:34:37 | stephenfin | bauzas: neither did I, but the CI failure is fairly unambiguous | |
| 09:34:54 | stephenfin | probably the implementation of getopt they're using is borked | |
| 09:35:04 | bauzas | in theory, you could also scp -rC | |
| 09:35:32 | gibi | I can reproduce the ordering requirement of scp locally | |
| 09:35:50 | gibi | so the manpage is incomplete :) | |
| 09:35:54 | bauzas | gibi: I honesly never used the -C flag | |
| 09:36:14 | bauzas | like I said, I tend to use tar over nc when I wanted to transfer large files | |
| 09:36:23 | stephenfin | tbf, parsing command line arguments is hard work | |
| 09:36:25 | bauzas | waaaaay more efficient | |
| 09:36:40 | gibi | scp is secure tar + nc is fast, it is a tradeoff :) | |
| 09:36:46 | stephenfin | so broken :-( | |
| 09:37:51 | stephenfin | to the point that click (which is actually awesome) uses the deprecated optparse. Less magical and more reliable, apparently | |
| 09:42:17 | gibi | stephenfin: btw https://that.guru/blog/the-numa-scheduling-story-in-nova/ is a great article that made me think about where and when nova selects the resources to consume | |
| 09:42:51 | bauzas | stephenfin: gibi: that's an argparse bug http://paste.openstack.org/show/796277/ | |
| 09:42:59 | bauzas | definitely not scp-related | |
| 09:43:04 | stephenfin | gibi: You can thank sean-k-mooney for most of that. I just spell checked and reorganized :) | |
| 09:43:29 | stephenfin | bauzas: Put '-C' at the end | |
| 09:43:36 | bauzas | oh that | |
| 09:43:43 | stephenfin | the issue isn't with the order of the positionals | |
| 09:43:44 | bauzas | of course, it won't work then | |
| 09:43:47 | stephenfin | options | |
| 09:43:55 | stephenfin | it's with options coming after positionals | |
| 09:44:01 | bauzas | you shock me if you thought it would work :p | |
| 09:44:13 | stephenfin | but it does in many applications! | |
| 09:44:21 | bauzas | but I honestly haven't paid attention at the argparse result :) | |
| 09:44:27 | openstackgerrit | Merged openstack/nova master: trivial: Test object backporting against correct version https://review.opendev.org/742650 | |
| 09:44:29 | bauzas | it NEVER worked with scp then :) | |
| 09:44:41 | bauzas | and many BSD commands | |
| 09:44:48 | bauzas | (many many) | |
| 09:46:19 | stephenfin | bauzas: http://paste.openstack.org/show/796278/ | |
| 09:46:31 | stephenfin | run that with e.g. 'python test.py 123 MB -b test' | |
| 09:46:39 | stephenfin | it'll work just fine | |
| 09:47:00 | stephenfin | so optparse (or whatever scp is using) is just plain broken | |
| 09:47:10 | stephenfin | but hey, I'm not going to fix it :) | |
| 09:48:25 | gibi | yeah 'grep foo ./ -R' works too | |
| 09:49:48 | gibi | sean-k-mooney: good article https://that.guru/blog/the-numa-scheduling-story-in-nova/ :) | |
| 09:50:25 | bauzas | stephenfin: fyk https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap12.html | |
| 09:50:55 | bauzas | tl;dr: options != operands | |
| 09:51:28 | bauzas | argparse was probably written by Linux geeks who weren't knowing about UNIX :p | |
| 09:51:37 | bauzas | time for a quote | |
| 09:52:43 | bauzas | BSD is what you get when a bunch of UNIX hackers sit down to try to port a UNIX system to the PC. Linux is what you get when a bunch of PC hackers sit down and try to write a UNIX system for the PC | |
| 09:53:45 | tosky | nice as a quote, even though iirc historically incorrect: when BSD started, there were no PC | |
| 09:54:17 | bauzas | that's not coming from me :) | |
| 09:54:43 | bauzas | but I used to play with some BSD OSes in the past, and this pun was very well known | |
| 09:55:19 | bauzas | do people know that 'ps' has a very specific POSIX syntax that people can use indefffrently from the OS ? | |
| 10:08:31 | stephenfin | bauzas: I was taught to use e.g. 'ps aux' which I think is BSD compatible too | |
| 10:09:29 | bauzas | that's correct, and that's the old syntax | |
| 10:09:51 | bauzas | we made it forward compatible | |
| 10:09:57 | bauzas | whoops | |
| 10:10:01 | bauzas | they, not we | |
| 10:10:12 | bauzas | I'm not THAT modest | |
| 10:10:55 | bauzas | tl;dr: options without the dash come from BSD | |
| 10:11:06 | bauzas | and Linux ported them | |
| 10:11:33 | bauzas | but in theory, you *should* always follow the POSIX syntax to be 100% compliant across all platforms | |
| 10:12:35 | bauzas | https://askubuntu.com/questions/484982/what-is-the-difference-between-standard-syntax-and-bsd-syntax | |
| 10:15:27 | bauzas | or slighly better https://man7.org/linux/man-pages/man1/ps.1.html | |
