Hi @ash2k. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with @k8s-bot ok to test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Details

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository. I understand the commands that are listed here.

@deads2k @sttts this is ready for review.

Made me think. Do we have a test anywhere that makes sure that this precondition is actually respected? 95% sure it works, but I don't think I've explicitly checked.

I don't know :)

staging/src/k8s.io/kube-apiextensions-server/test/integration/finalization_test.go

I understand this test, but its an esoteric flow. Can you add comments explaining that deleting something with a finalizer sets deletiontimestamp, but leaves the item until the finalizer list is empty and someone issues another delete?

deads2k · 2017-05-26T11:50:29Z

staging/src/k8s.io/kube-apiextensions-server/test/integration/finalization_test.go

I think you should be able to issue another delete and have the item remain since the finalizer isn't finished. Can you confirm with a normal resource and add this check if so?

ok, will do.

deads2k · 2017-05-26T11:51:14Z

staging/src/k8s.io/kube-apiextensions-server/test/integration/finalization_test.go

I'm surprised the final delete wasn't instantaneous. You confirmed that you had to wait? Any idea why?

I haven't confirmed whether it was or was not instantaneous - I'm following my past experience with deletes where a delete of an object does not remove it from api immediately and you can GET it and observe the deletion timestamp set. And then it disappears.

Works without Polling as well. 👍

deads2k · 2017-05-26T11:51:52Z

A few comments, but this looks very good. Glad it works for you :)

ash2k · 2017-05-26T11:56:09Z

Well, it works 50% of the time. It's extremely flaky. Here are some failures:

This is obviously not acceptable to merge. I don't think it is a test though. Looks like some server-side issues.

ash2k · 2017-05-26T11:58:29Z

The first one is really weird - it is an UPDATE conflict but resource version is the same "5" before the update and after an update failure.

ash2k · 2017-05-26T12:58:09Z

Two new types of failures.
This one is the situation where PollImmediate times out after 3 seconds and the object is still in the api after delete.

@deads2k is better equipped to explain those errors but fwiw, the tests are passing for me everytime! :)

Remove the poll. It should not flake, but if it does, we'll chase it.

deads2k · 2017-05-26T14:19:15Z

@k8s-bot ok to test

deads2k · 2017-05-26T14:19:37Z

I haven't managed to see it flake. Let's see what CI says.

Fix the poll and squash please.

@ash2k staging godeps want to be updated.

ash2k · 2017-05-29T10:46:07Z

@sttts hey, thanks for the tip - this is all new to me, I thought the failures were caused by something else, not my pr. How do I do this? I tried running ./hack/update-staging-godeps.sh but it outputs an error and I don't know how to proceed:

./hack/update-staging-godeps.sh 
Checking whether godeps are restored
Updating godeps for k8s.io/apimachinery
Rewriting Godeps.json to remove commits that don't really exist because we haven't pushed the prereqs yet
Updating godeps for k8s.io/apiserver
  godep: Package (github.com/emicklei/go-restful/swagger) not found

Call stack:

  2: ./hack/update-staging-godeps.sh:103 main(...)

Looks like k8s.io/apiserver wants github.com/emicklei/go-restful/swagger but I haven't touched that directory.

sttts · 2017-05-29T11:10:24Z

hey, thanks for the tip - this is all new to me

No problem :)

Can you try to run hack/godep-restore.sh? Might be that this must be called once before.

ash2k · 2017-05-29T22:37:18Z

So the solution was to follow https://github.com/kubernetes/community/blob/master/contributors/devel/godep.md to the letter. Just using those scripts with my existing gopath didn't work. Magic!

ash2k · 2017-05-29T23:54:43Z

@deads2k please take a look at the CI test failure - it is something I'm getting locally too, so cannot just be my local (incorrect?) setup:

assertions.go:203: 
                        
	Error Trace:	finalization_test.go:75
	
	Error:		Received unexpected error "the server reported a conflict (put noxus.mygroup.example.com foo123)"

sttts · 2017-05-30T07:24:33Z

staging/src/k8s.io/kube-apiextensions-server/test/integration/finalization_test.go

You need a retry loop here which does the get-change-update pattern as long as errors.IsConflict(err) is true.

Background: the controllers in the master will update the object. If you use the your old copy in line 74 the apiserver will complain that your version is outdated. Even line 64 will modify the object (it sets the deletion timestamp).

That explains the spurious failures. I didn't know some other controllers will/may modify the object concurrently.
However then the question is why it was passing sometimes if line 64 always modifies it before the update? I tried to troubleshoot this earlier (see last block in comment #46439 (comment)) and found that resource version was the same before and after the failed update operation so I thought there should be no conflict even though the conflict is reported. Weird. Delete does not increment the resource version but is checked on conditional update?
Anyway, I've updated the code. Thanks for the help!
