k8s-merge-robot 590a5f3ad7 Merge pull request #23444 from deads2k/add-requeue-after-duration 
Automatic merge from submit-queue

add a delayed queueing option to the workqueue

Adds delayed requeuing to the workqueue so that I requeue an item to be retried at some later time in my controller with a series of backoff rules.  It lets me have the best of the retryManager and the work queue de-duping.  Tracking failures and backoffs is on the caller

@smarterclayton @pweil-  this would help us move to using the informer everywhere and de-duping at that level.

Automatic merge from submit-queue

Add path to log messages.

It is useful to see the path that failed to mount in the log messages.

Fixes #23990.

k8s-merge-robot ae57644172 Merge pull request #23435 from jsafrane/devel/fix-nsenter-mkdir 
Automatic merge from submit-queue

Fixed mounting with containerized kubelet

`NsenterMounter.IsLikelyNotMountPoint()` should return `ErrNotExist` when the
checked directory does not exists - the regular mounted does this and
some volume plugins depend on this behavior.

See for example: https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/aws_ebs/aws_util.go#L72

Automatic merge from submit-queue

Implement a streaming serializer for watch

Changeover watch to use streaming serialization. Properly version the
watch objects. Implement simple framing for JSON and Protobuf (but not
YAML).

k8s-merge-robot fcddb9cba5 Merge pull request #16964 from liggitt/json_precision 
Automatic merge from submit-queue

Preserve int data when unmarshaling

There are several places we use `json.Unmarshal` into an unstructured map (StrategicMergePatch, UnstructuredJSONScheme, many others).

In this scenario, the json package converts all numbers to float64. This exposes many of the int64 fields in our API types to corruption when the unstructured map is marshalled back to json.

A simple example is a pod with an `"activeDeadlineSeconds": 1000000`. Trying to use `kubectl label`, `annotate`, `patch`, etc results in that int64 being converted to a float64, submitted to the server, and the server rejecting it with an error about "cannot unmarshal number 1e+6 into Go value of type int64"

The json package provides a way to defer conversion of numbers (`json.Decoder#UseNumber`), but does not actually do conversions to int or float. This PR makes use of that feature, and post-processes the unmarshalled map to convert json.Number objects to either int64 or float64 values

k8s-merge-robot 5c2f758517 Merge pull request #17590 from fabianofranz/cli_homedir_on_windows 
Automatic merge from submit-queue

Use correct home directory on Windows

As of now the `kubectl` config mechanism that saves/loads `~/.kube/config` is broken on Windows, saving the config file in the *current* directory instead of the user's *home* dir. This happens because most Windows don't respect the `HOME` environment variable. 

This PR changes the config file loading mechanism to use the recommended way to detect the user home on Windows (`HOMEDRIVE`+`HOMEPATH` or `USERPROFILE`), and adds a migration for users that might be currently relying on existing config files.

Clayton Coleman de6e02d8bb interrupt package (attach and edit) could leak a goroutine 
os/signal.Stop() does not actually close the channel, which means
the channel is blocked. Not serious because we don't use interrupt
protection on the server, just the CLI (which can afford 1 leaked
goroutine).

Currently attach and the editor do not share the same logic for saving

caller wants to create something, attach, and then delete something when
the attach is over).  This commit moves the interrupt protection logic
to a util package and supports nesting interrupt handlers.

Michail Kargakis 77097d9a20 kubectl: set maxUnavailable to 1 if both fenceposts resolve to zero 
Due to rounding down for maxUnavailable, we may end up with rolling updates
that have zero surge and unavailable pods something that 1) is not allowed
as per validation, 2) blocks updates. If we end up in such a situation
set maxUnavailable to 1 on the theory that surge might not work due to
quota.

Jan Chaloupka 3fa290980a jitter period in each run of Until 
In order to synchronize the current state of Kubernetes's objects (e.g. pods, containers, etc.),
periodic synch loops are run. When there is a lot of objects to synchronize with,
loops increase communication traffic. At some point when all the traffic interfere cpu usage curve
hits the roof causing 100% cpu utilization.

To distribute the traffic in time, some sync loops can jitter their period in each loop
and help to flatten the curve.

This commit adds JitterUntil function with jitterFactor parameter.
JitterUntil generalizes Until which is a special case for jitterFactor being zero.

Jan Safranek 220163f67d Fixed races in Cinder volume attach/detach. 
Add a mutex to guard SetUpAt() and TearDownAt() calls - they should not
run in parallel.  There is a race in these calls when there are two pods
using the same volume, one of them is dying and the other one starting.

TearDownAt() checks that a volume is not needed by any pods and detaches the
volume. It does so by counting how many times is the volume mounted
(GetMountRefs() call below).

When SetUpAt() of the starting pod already attached the volume and did not mount
it yet, TearDownAt() of the dying pod will detach it - GetMountRefs() does not
count with this volume.

These two threads run in parallel:

 dying pod.TearDownAt("myVolume")          starting pod.SetUpAt("myVolume")
   |                                       |
   |                                       AttachDisk("myVolume")
   refs, err := mount.GetMountRefs()       |
   Unmount("myDir")                        |
   if refs == 1 {                          |
   |  |                                    Mount("myVolume", "myDir")
   |  |                                    |
   |  DetachDisk("myVolume")               |
   |                                       start containers - OOPS! The volume is detached!
   |
   finish the pod cleanup


Also, add some logs to cinder plugin for easier debugging in the future, add
a test and update the fake mounter to know about bind mounts.

Add a recognizer that is capable of sniffing content type from data by
asking each serializer to try to decode - this is for a "universal
decoder/deserializer" which can be used by client logic.

Add codec factory, which provides the core primitives for content type
negotiation. Codec factories depend only on schemes, serializers, and
groupversion pairs.
