Ondra Kupka edad3048e9 kubectl: Cache Verifier.HasSupport calls 
The underlying implementation decodes OpenAPI schema on every HasSupport
call. This causes these calls to be expensive and noticable when many
resources are being applied.

This patch wraps the verifier with a thread-safe cache so that when many
resources of the same kind are being checked, only the first call
includes schema decoding.

This solution is specifically limited to the kubectl codebase without
any changes required in client-go, for now, although that is where the
issue is actually originating.

Build Status GoDoc

The k8s.io/kubectl repo is used to track issues for the kubectl cli distributed with k8s.io/kubernetes. It also contains packages intended for use by client programs. E.g. these packages are vendored into k8s.io/kubernetes for use in the kubectl cli client. That client will eventually move here too.

Contribution Requirements

  • Full unit-test coverage.

  • Go tools compliant (go get, go test, etc.). It needs to be vendorable somewhere else.

  • No dependence on k8s.io/kubernetes. Dependence on other repositories is fine.

  • Code must be usefully commented. Not only for developers on the project, but also for external users of these packages.

  • When reviewing PRs, you are encouraged to use Golang's code review comments page.

  • Packages in this repository should aspire to implement sensible, small interfaces and import a limited set of dependencies.
