clarkbcorvus: I've approved the change. I worry the "naked" del project will be subject to future cleanups but I agree that removing the potnetial confusion is a good idea00:01
corvusoh yeah, i guess i could have added a comment00:12
fungii did wonder about that. the commit message made the reason clear, but in retrospect a comment would have helped00:41

corvusswest: i have a question on that, can you check in gerrit?  https://review.opendev.org/80517513:18
corvusswest: i don't understand which test is faulty and why13:19
swestcorvus: the additional test I added is not faulty, but if you want to reproduce the describe issue with the current master you might need to run it multiple times13:19
swestthe order in which the tenant reconfig events are processed is not deterministic13:20
corvusswest: because the first change touches both tenants, ok13:21
swestcorvus: let me know if I should clarify this in the commit message13:22
corvusswest: why isn't it deterministic?13:23
swestcorvus: I haven't checked13:26
corvusokay, i'll try to figure that out; i don't like the idea of merging a test we know isn't reliable13:27
swestit's reliable in the current form, it's just not reliable for reproducing the issue with current master :)13:27

*** sshnaidm is now known as sshnaidm|afk16:09
fajfercorvus: hey, thanks. I'd hate to be that guy so I realised I'd just hang out a bit first. I've been using Zuul for over a year now, just having some random trouble with a job not being queued properly (like if I didn't pass eg. branch criteria). If I copy the job from the config into the zuul.yaml it works flawlessly16:09
fajferconfig project into the zuul.yaml untrusted project - just to make stuff clear16:09
fungiexplicit vs implicit branch filters can be tricky. zuul will attempt to use configuration from untrusted projects by matching branch names between them (unless you override the branch matching). failing that, it will check the default branch (usually "master" or "main" depending on how the project is configured)16:13
fungiyou can add explicit branch filters in projects, but that's usually only recommended to do when defining the job in a single-branch repository, as zuul does a better job at using branched configuration (reading configuration from the intended branch of the project) if the job is defined in a multi-branch repository16:14
fungialso having more than one branch in a trusted config project can lead to problems, i think it only uses configuration from the default branch of config project though i need to double-check the docs on that point16:15
fajferthe trusted config project uses only one branch16:15
fajferand I think you're right16:16
fungiso anyway, you've got a (single-branch) config project defining a job with some explicit branch matcher declared, and you're adding that job in a project-pipeline for some project but it's not being triggered?16:17
fajferthe problem I got is I got a config project containing several jobs, and I got this development project which is untrusted. If the job definition remains in the config project, this sole job doesn't trigger in the pipeline. Copied over to the zuul.yaml on development project triggers properly16:19
fungiis there anything unique about the job which isn't running? like does it use secrets while the others don't?16:20
fungior does it have a different inheritance path, and maybe there's something about its parent job which is the cause?16:21
corvusDamian Fajfer: if you're an admin, you can run the scheduler with debug logs enabled and zuul will log why it isn't running a job.  as a user, you can set this value and get the same information in the report (you might need a noop job running to make it report): https://zuul-ci.org/docs/zuul/reference/project_def.html#attr-project.%3Cpipeline%3E.debug16:21
corvusDamian Fajfer: If it is related to branches, as fungi suspects, you might find pragmas interesting: https://zuul-ci.org/docs/zuul/reference/pragma_def.html16:22
corvusand also make sure you're familiar with the branch logic fungi describes -- https://zuul-ci.org/docs/zuul/reference/job_def.html#attr-job.branches16:23
fungiwell, the only reason i got fixated on branches was fajfer's comment about "random trouble with a job not being queued properly [...] didn't pass eg. branch criteria"16:24
fungibut maybe i misunderstood and it was an example of prior challenges not related to the current one16:24
corvusit's a good guess16:24
corvuseither way, logs should tell16:25
fungicertainly the branch matcher logic is some of zuul's more magical behavior16:25
fungi(or seems that way until you read the explanation in the docs anyway)16:25
corvusmagical but not mysterious16:26
fajferhttps://dpaste.com/4FYGKKQSK this is the structure I got16:34
fajferI have a very similar job to this that works flawlessly in all variants, I just can't get this problematic-job to work16:35
fajferI'm gonna try the logs for sure16:35
fungiif there are secrets involved, then job selection gets more complicated as zuul has a number of safeguards in place to make it hard for those to be triggered in situations where the secrets could be exposed by a user. you are adding it to a post-review pipeline, right? and where is the secret defined?16:42
fajfersimilar to opendev - zuul.d/secrets.yaml in a config project16:43
fajferand yeah I confirm this is in a post-review: true pipeline16:44
fungiand the playbooks which use that secret are defined in the config project as well in that case, and the parent jobs don't utilize the secret or you're using pass-to-parent explicitly for them?16:44
fajfersecrets have pass-to-parent: true16:45
fungimight be good to review the caveats listed at https://zuul-ci.org/docs/zuul/reference/secret_def.html if you haven't already, just to be sure the cause isn't one of those16:45
fajferit works overall, I'm just really having some trouble with one job not being queued16:46
fajferbut feel free to ask away, I've read the docs, I don't seem to find anything that could help  me :(16:46
fungiand you're not using an allowed-projects list with that job presumably? though that would probably have jumped out at you already if you were16:46
corvusit will be much more efficient to check the logs16:47
fungiyep, agreed16:47
fungithe reasons zuul might *not* run something are rather numerous16:47
fajferyeah, but that's the first time I'm totally disoriented16:48
fajfermight need to increase the verbosity or something, I think I missed that one article16:48
corvusclarkb: i realized that the request is removed on the merger without subsequent log lines related to that on the scheduler, so our missing merge request from earlier was actually run and completed on ze0416:50
clarkbah16:51
corvusi will make log improvements in a bit; for now i'll track down the next link16:51
corvusclarkb: the merge failed:   stderr: 'ssh: Could not resolve hostname review.opendev.org: Temporary failure in name resolution16:52
fungithat's a surprising error16:53
clarkbwe've seen it before. It prompted us to bump the ttl on the record back to an hour16:53
clarkbcorvus: I would expect that to cause zuul to report an error back at least?16:53
corvusyeah, i think it didn't submit a completed event; should be able to repro and fix16:54
fungiwas that stderr from a task on a job node? we've also seen it happen more on providers where a v4 nat is in use (though generally we prefer resolution over ipv6 in those places)16:54
clarkbfungi: no on the zuul merger. The change didn't run any jobs because its initial merge never compelted16:54
fungioh, this was from attempting to make a connection to the api?16:55
fungineat16:55
fungiso one of our mergers had name resolution issues16:55
clarkbside note: dns resolution problems aren't related to the gerrit server move. I wonder if we're seeing flakier network in general16:55

corvusclarkb, fungi: actually, here's the log improvements first17:00
fajferI just put the job into check instead to post to hasten my debugging and it queued17:03
fungiyeah since the job is defined in a config project, even though it uses a secret, it can be enqueued into a pre-review pipeline17:11
fungibecause config projects don't get speculative execution of job configuration changes17:12
fungiso i guess there's something about the job which is causing it not to match the conditions of your post pipeline, but does match the conditions for your check pipeline17:14

clarkbTylerPearce[m]: did you make sure the PR was approved as that is listed as a requirement. The PR must also be in an open state18:05
clarkbThen you trigger the jobs by leaving a comment with 'merge' in it or label the PR merge is I am reading the pipeline definition properly18:06
fungibut switching the gate pipeline described in that example from manager: dependent to independent works even when not altering the require and trigger parameters?18:06
TylerPearce[m]Ah sorry, the "gate" pipeline always works. Just the "check" pipeline does not work when changing the manager to `dependent`18:08
TylerPearce[m]The check pipeline should trigger from a comment 'recheck', but this only seems to trigger if the manager is `independent`, regardless of approval/open status18:08
fungiahh, so your "gate" pipeline in that example, which is set to manager: dependent, is already working18:08
TylerPearce[m]Yes the "gate" pipeline is working, I'm just trying to test some things on a dependent pipeline without actually merging anything18:09
fungii wonder if the dependent pipeline manager implicitly checks for mergeable conditions18:10
* TylerPearce[m] uploaded an image: (169KiB) < https://matrix.org/_matrix/media/r0/download/matrix.org/PTjJoCJOqMOCnAEaMeUYufSH/image.png >18:11
TylerPearce[m]I tried commenting "recheck" on an approved/open PR which didn't seem to trigger anything, then "merge" right after which worked successfully. The merge conditions should have been the same for both triggers, I think18:11
fungii don't see any mention of the dependent pipeline manager having special expectations as far as the github checks api driver has documented18:13
TylerPearce[m]Yeah I didn't see anything either, but I'm struggling to understand why my "check" pipeline isn't running here. I can work around this by just testing on the "gate" pipeline, I just like to know why things aren't working the way I expect them to XD18:14
fungii've not seen the dependent pipeline manager used for pre-approval pipelines, so it's possible there's some nuance of the pipeline managers coming into play we've just not exercised there18:14
fungiusually dependencies in pre-approval testing are declared explicitly between changes or implicitly via git parenting, so i'm not sure how teh dependent manager would function in that scenario18:15
fungii guess the desire is for your check pipeline to be sequenced based on trigger time?18:16
fungii would expect that to create some significant delays in getting test results reported on open changes, but there's probably some workflow involved there i'm just not able to imagine without additional context18:17
TylerPearce[m]My goal here is to get a better understanding of how project gating (https://zuul-ci.org/docs/zuul/discussion/gating.html?highlight=project%20gating) works, so I was planning on experimenting with some stuff in a dependent pipeline18:18
TylerPearce[m]Ultimately my company wants to continue using CircleCI to run our test suites, so I need some way of communicating to CircleCI exactly what changes it should test18:18
TylerPearce[m]Using a dependent pre-approval pipeline was just for my own testing, the "check" pipeline I plan to use in production will be a standard independent pipeline18:19
TylerPearce[m]I can still run my experiments in the gate pipeline, so it's not an issue :) I was just curious if I was missing something obvious18:21
fungiit's an interesting experiment, i've just not seen the dependent pipeline manager applied to a check-like pipeline so not exactly sure what to expect. the lack of enqueuing is certainly an interesting outcome18:22
fungiwe don't seem to document anything at https://zuul-ci.org/docs/zuul/reference/pipeline_def.html#value-pipeline.manager.dependent which would imply there's a system-wide expectation precluding what you're trying, but i wouldn't be entirely surprised to find that there could be assumptions in some of the connection drivers around triggering conditions18:26
TylerPearce[m]I'll poke around a little bit and report back if I find anything. Thanks for talking through this with me!18:28
fungino worries, sorry i didn't have any better insights, but maybe someone else here has tried the same thing or knows about nuances of the github driver which could be complicating your experiment18:29

clarkbbridgefan: the log url becomes an attribute of the build page and does not replace it20:27

I had previously required "check" and "gate" to pass as part of the branch protection rules in GitHub.

corvusclarkb: i agree with your nit.  in my defense, that ordering was a late refactor (it's like version 3 of that method) and so i wasn't thinking about it chronologically.  but i also agree, it's not worth another ps.23:17
clarkbcorvus: I've approved the parent now but also left a coupel of minor things there23:25
clarkbianw: I like https://review.opendev.org/c/zuul/zuul/+/804956 now that i can see what it does via the site preview. I did leave a comment on one of the Job page changes. I'm not a fan of the two columns of stuff. Much prefer the single list of key: value pairs23:29
corvusClark: replied.23:30
clarkbcorvus: oh I see taht is what you meant in the commit message23:32
ianwclarkb: yeah, i responded, not sure it makes sense to call out the description if not using 2 columns.  it's subjective, i don't really mind23:37
clarkbresponded. I don't feel super strongly about it if others prefer that rendering23:39
