Automatic merge from submit-queue Refactor persistent volume controller Here is complete persistent controller as designed in https://github.com/pmorie/pv-haxxz/blob/master/controller.go It's feature complete and compatible with current binder/recycler/provisioner. No new features, it *should* be much more stable and predictable. Testing -- The unit test framework is quite complicated, still it was necessary to reach reasonable coverage (78% in `persistentvolume_controller.go`). The untested part are error cases, which are quite hard to test in reasonable way - sure, I can inject a VersionConflictError on any object update and check the error bubbles up to appropriate places, but the real test would be to run `syncClaim`/`syncVolume` again and check it recovers appropriately from the error in the next periodic sync. That's the hard part. Organization --- The PR starts with `rm -rf kubernetes/pkg/controller/persistentvolume`. I find it easier to read when I see only the new controller without old pieces scattered around. [`types.go` from the old controller is reused to speed up matching a bit, the code looks solid and has 95% unit test coverage]. I tried to split the PR into smaller patches, let me know what you think. ~~TODO~~ -- * ~~Missing: provisioning, recycling~~. * ~~Fix integration tests~~ * ~~Fix e2e tests~~ @kubernetes/sig-storage <!-- Reviewable:start --> --- This change is [<img src="http://reviewable.k8s.io/review_button.svg" height="35" align="absmiddle" alt="Reviewable"/>](http://reviewable.k8s.io/reviews/kubernetes/kubernetes/24331) <!-- Reviewable:end --> Fixes #15632 |
