We are not sure why this was stdout, since stdin is what the user uses to pass
information to the exec plugin.
There is a question of backwards compatibility here. Our take is that this is a
bug, and so we are ameliorating behavior instead of breaking behavior. There are
2 main cases to consider with respect to backwards compatibility:
1. an existing exec plugin depended on stdin being hooked up to them if stdout
was a terminal (e.g., echo foo | client-go-command-line-tool); we believe
this is an anti-pattern, since the client-go-command-line-tool could be using
stdin elsewhere (e.g., echo foo | kubectl apply -f -)
2. an existing exec plugin depended on stdin not being hooked up to them if
stdout was not a terminal (e.g., client-go-command-line-tool >/dev/null);
hopefully there are very few plugins that have tried to base logic off of
whether stdin returned EOF immediately, since this could also happen when
something else is wrong with stdin
We hope to apply a stronger fix to this exec plugin user interaction stuff in a
future release.

This updates the EndpointSlice controller to make use of the
EndpointSlice tracker to identify when expected changes are not present
in the cache yet. If this is detected, the controller will wait to sync
until all expected updates have been received. This should help avoid
race conditions that would result in duplicate EndpointSlices or failed
attempts to update stale EndpointSlices. To simplify this logic, this
also moves the EndpointSlice tracker from relying on resource versions
to generations.
Right now, there is no way to use these annotations, support multiple
`kubectl` versions, and not give users annoying warnings every time they
run `kubectl log`.
If a user is setting *both* annotations, they clearly know that the old
on is deprecated. Therefor, we should not warn them.
`find_files` had incorrect regexes which led to `genswaggertypedocs`
never being invoked. This commit updates the regex to correctly
look for versioned API types.go files.
Since `genswaggertypedocs` was never invoked, there are many API types
with missing descriptions. This commit lists these `types.go` files
in `hack/.descriptions_failures`.
The `verify-description.sh` script skips running `genswaggertypedocs`
on the files listed in `hack/.descriptions_failures`.
Set the container cpuset.memory during the creation and avoid an additional
call to the resources update of the container.

A CounterVector with status as label may create unnecessary overhead
and using the success case with the empty label value wasn't
easy. It's better to have two seperate counters, one for total number
of calls and one for failed calls.
GetCounterMetricValue has an unchecked conversion to metrics.Metric,
something that didn't work for a *Counter because it didn't implement
that interface.
As discussed during the production readiness review, a metric for the
PVC create operations is useful. The "ephemeral_volume" workqueue
metrics were already added in the initial implementation.
The new code follows the example set by the endpoints controller.
When the feature is disabled either in the scheduler or the CSIDriver,
the scheduler is expected to schedule pods without considering whether
storage capacity is available.
