#openstack-nova - 2019-05-28
17:32:25 spatel sean-k-mooney: hey
17:32:38 efried aspiers: (are you aware of the meaning of the orange dots and green tildes?)
17:32:41 aspiers OK, so essentially you want me to ditch my third goal? which is totally fine by me
17:32:46 aspiers yep, I had figured that out
17:33:41 aspiers I can understand the desire to eliminate orange dots. Why do you want to avoid green tildes though?
17:34:03 efried aspiers: well, I may be telling you that you may be reversing goals 2 and 3 :) at least from my pov
17:34:27 aspiers ACK, just trying to understand the cause of the confusion
17:34:29 efried because it means that those patches are based on older versions of these
17:34:43 efried it's usually a signal that you're still in the process of rebasing and cleaning things up.
17:34:56 aspiers ... which in the third example you listed is true
17:35:10 efried which is reinforced by having just WIP'd one near the bottom
17:35:20 efried anyway, again, I'm not trying to hurry you along.
17:35:29 aspiers I don't mind being hurried :)
17:35:56 efried just wanted to confirm that you're still shuffling the paperwork, as opposed to thinking you're ready for reviews and then getting frustrated when they don't happen
17:36:21 aspiers Well, this is a very useful discussion
17:37:18 aspiers It highlights that the unavoidable impact of deciding not to review anything within a given topic until all tildes and dots are gone, is that every time I need to change something minor lower in the dependency tree, I have to rebase every single thing above it before the new patchset gets reviewed
17:37:40 aspiers To me this highlights a failure in Gerrit's UI
17:38:17 efried or a failure in my method of working.
17:38:20 aspiers Ideally reviews would only be blocked if stale stuff is *below* them, not above
17:38:28 efried "blocked" is a bit strong
17:39:11 efried It's just the typical workflow I see (and use) is, when something needs to be fixed on a lower patch, download the whole series, git restack, fix the issues below, which automatically rebases the rest of the way up, and resubmit the whole series.
17:39:17 efried Agree that consumes a lot of CI resources
17:39:37 efried but it also ensures that the top changes will legitimately work with however the lower changes have been altered.
17:39:48 aspiers Sure
17:39:57 aspiers I'm not saying I want to avoid rebasing things
17:40:25 aspiers Just wondering if the presence of WIP higher up the tree should have an impact on stuff lower in the tree
17:41:16 aspiers If I understand the Gerrit UI correctly, we're talking about whether a patch in the Related Changes list has dots or tildes *below* it, right?
17:42:07 efried I'm not sure it's possible to have tildes below or dots above.
17:42:29 aspiers Oh, good point
17:42:29 efried I mean, technically possible, but you would really have to be trying.
17:42:29 efried ...unless you're looking at a PS that itself has a dot
17:42:30 efried anyway
17:42:57 efried the presence of WIP higher in the tree (which is not the same thing as a tilde, btw) should not impact reviews lower.
17:43:21 efried so this is probably just me being used to one workflow and you using a different one to (rightly) try to conserve CI resources.
17:44:18 aspiers Well, it's also about me needing to pay more attention to orange dots in Related Changes, so I can spot when rebases are needed
17:44:20 efried moot right now because I've reviewed everything up to the first one that's actually titled WIP, so regardless of colored decorations, I'm stopping here.
17:44:52 aspiers the WIP one is only marked WIP because of the required-projects hack. Other than that I think it's ready to go
17:44:56 efried but yeah, usually a patch that's riding an orange dot should be rebased if it's to get serious attention.
17:45:20 aspiers At least, other than rebasing (which I'll do now) I've run out of improvements to make to it
17:46:21 aspiers I put WIP on it because mriedem asked me to, but the only element of WIP there is that kashyap's os-traits patch hasn't landed and been released yet.
17:48:07 aspiers efried: also, since we're putting the workflow under the microscope, should I be putting the SEV blueprint: in the commit message and topic for changes like refactorings, which aren't per se SEV-related, but still form part of the SEV series?
17:48:39 efried nah
17:48:43 aspiers ok

18:01:18 aspiers efried: got rid of some orange dots
18:05:09 aspiers (and that's from someone who's worked with them)
18:16:59 openstackgerrit Matt Riedemann proposed openstack/nova master: Workaround missing RequestSpec.instance_group.uuid https://review.opendev.org/661786

18:34:09 ganso lyarwood, melwitt, dansmith, tonyb: Hello! When you have a minute, could you please take a look at those backports? https://review.opendev.org/#/c/652153 , https://review.opendev.org/#/c/658136 and https://review.opendev.org/#/c/661349 ? Thanks in advance! =)
18:44:14 aspiers efried: if CONF.libvirt.num_memory_encrypted_guests is not set and therefore defaults to None (meaning as we agreed in the spec, "auto-detect the inventory, if if this isn't possible, don't impose any limit), what should the MEM_ENCRYPTION_CONTEXT inventory get set to?
18:44:30 aspiers I'm not sure we came to a consensus with jaypipes on this http://eavesdrop.openstack.org/irclogs/%23openstack-nova/%23openstack-nova.2019-04-23.log.html#t2019-04-23T17:55:57
18:48:58 efried aspiers: MAXINT
18:49:10 jaypipes aspiers: not sure you need any consensus. :)
18:51:18 aspiers jaypipes: OK :)
19:57:19 openstackgerrit John Garbutt proposed openstack/nova master: WIP: Integrating with unified limits https://review.opendev.org/615180

22:45:15 eandersson What is the network cache used for on the computes?
22:45:43 openstackgerrit Adam Spiers proposed openstack/nova master: extract baselineCPU API call from _get_cpu_traits() https://review.opendev.org/661782
22:45:57 eandersson We found that with a high number of computes, the whole heal instance info cache got a little too chatty on the default setting.
22:46:32 aspiers efried: at risk of highlighting my own incompetence, this is the kind of change where normally I'd be inclined to avoid a rebase of everything sitting on top: https://review.opendev.org/#/c/661782/3..4/nova/virt/libvirt/driver.py
22:47:00 aspiers efried: that said, I'm totally fine with rebasing if you'd prefer that
22:47:56 aspiers ah actually, since splitting out some other patches, there's only one patch sitting on top
22:48:02 aspiers so maybe I will anyway
22:49:37 aspiers hah, especially considering zuul absolutely hates that change sitting on top
22:49:49 efried aspiers: I respect your green-ness. And maybe you'll start a sea change in nova. All I'm saying is that all the series contributions I've seen in my (albeit limited) time here have been managed in a series-as-a-whole fashion.
22:50:39 aspiers efried: fine by me :) I maintain the belief that Gerrit should visualise the dependency tree in a way which would make this kind of stuff a no-brainer
22:50:57 aspiers but until it gets smarter, I'm happy to do whatever to make reviews easier
22:51:59 efried aspiers: I use the tree-shaped version of git log locally, do you?
22:52:14 efried To me, that sounds more or less like the visualization you're talking about...
22:52:17 aspiers I use gitk, but that shows the history, not the real dependency tree
22:52:26 efried ...and in that visualization, the way it's expressed is bang on.
22:52:54 efried i.e. you can't say that PS4 of X is based on PS2 of Y when it's in fact based on PS1 of Y.
22:53:05 aspiers I'm talking about semantic dependencies https://aspiers.github.io/nashville-git-automagic-april-2019/#/git-deps-concept
22:53:07 efried Because PS1 and PS2 of Y could be *wildly* bifferent.
22:53:11 efried or even different.
22:53:25 aspiers I like bifferent, it should be a word
22:53:47 efried Back to the Future referential, somehow.
22:53:54 aspiers :)
22:54:13 efried like how a guy can be a jerk until you go back in time and kick his ass, then when you come back to the present, he's bifferent.
22:54:32 aspiers exactly :)
22:55:06 aspiers actually that was misleading - git-deps deals in textual dependencies, but here I mean semantic ones
