The "// import <path>" comment has been superseded by Go modules.
We don't have to remove them, but doing so has some advantages:
- They are used inconsistently, which is confusing.
- We can then also remove the (currently broken) hack/update-vanity-imports.sh.
- Last but not least, it would be a first step towards avoiding the k8s.io domain.
This commit was generated with
sed -i -e 's;^package \(.*\) // import.*;package \1;' $(git grep -l '^package.*// import' | grep -v 'vendor/')
Everything was included, except for
package labels // import k8s.io/kubernetes/pkg/util/labels
because that package is marked as "read-only".
Windows proxy metric registration was in a separate file, which had
led to some metrics (eg the new ProxyHealthzTotal and ProxyLivezTotal)
not being registered for Windows even though they were implemented by
platform-generic code.
(A few other metrics were neither registered on, nor implemented on
Windows, and that's probably a bug.)
Also, beyond linux-vs-windows, make it clearer which metrics are
specific to individual backends.
