`Get` method within the fake clientset returns an object that would not be normally returned when using the real clientset. Reproducer:
```go
package main
import (
v1 "k8s.io/api/core/v1"
metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
"k8s.io/client-go/kubernetes/fake"
)
func main () {
cm := &v1.ConfigMap{
ObjectMeta: metav1.ObjectMeta{Namespace: metav1.NamespaceSystem, Name: "cm"},
}
client := fake.NewSimpleClientset(cm)
obj, err := client.CoreV1().ConfigMaps("").Get("", metav1.GetOptions{})
if err != nil {
panic(err)
}
fmt.Printf("obj: %#v\n", obj)
}
```
stored under `test.go` of `github.com/kubernetes/kubernetes` (master HEAD) root directory and ran:
```sh
$ go run test.go
obj: &v1.ConfigMap{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:v1.ObjectMeta{Name:"cm", GenerateName:"", Namespace:"kube-system", SelfLink:"", UID:"", ResourceVersion:"", Generation:0, CreationTimestamp:v1.Time{Time:time.Time{wall:0x0, ext:0, loc:(*time.Location)(nil)}}, DeletionTimestamp:(*v1.Time)(nil), DeletionGracePeriodSeconds:(*int64)(nil), Labels:map[string]string(nil), Annotations:map[string]string(nil), OwnerReferences:[]v1.OwnerReference(nil), Finalizers:[]string(nil), ClusterName:"", ManagedFields:[]v1.ManagedFieldsEntry(nil)}, Data:map[string]string(nil), BinaryData:map[string][]uint8(nil)}
```
As you can see fake clientset with a "test" configmap is created. When getting the object through the clientset back, I intentionally set the object name to an empty string. I would expect to get an error saying config map "" was not found. However, I get "test" configmap instead.
Reason for that is inside implementation of `filterByNamespaceAndName` private function:
```go
func filterByNamespaceAndName(objs []runtime.Object, ns, name string) ([]runtime.Object, error) {
var res []runtime.Object
for _, obj := range objs {
acc, err := meta.Accessor(obj)
if err != nil {
return nil, err
}
if ns != "" && acc.GetNamespace() != ns {
continue
}
if name != "" && acc.GetName() != name {
continue
}
res = append(res, obj)
}
return res, nil
}
```
When `name` is empty, `name != "" && acc.GetName() != name` condition is false and thus `obj` is consider as a fit.

Kubectl
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.
Dependencies
Dependencies are managed using dep. Please refer to its documentation if needed.
