var EmptyFields = func() metav1.FieldsV1 {
	f, err := SetToFields(*fieldpath.NewSet())
	if err != nil {
		panic("should never happen")
	return f

EmptyFields represents a set with no paths It looks like metav1.Fields{Raw: []byte("{}")}


func BuildManagerIdentifier

func BuildManagerIdentifier(encodedManager *metav1.ManagedFieldsEntry) (manager string, err error)

BuildManagerIdentifier creates a manager identifier string from a ManagedFieldsEntry

func EncodeObjectManagedFields

func EncodeObjectManagedFields(obj runtime.Object, managed ManagedInterface) error

EncodeObjectManagedFields converts and stores the fieldpathManagedFields into the objects ManagedFields

func FieldsToSet

func FieldsToSet(f metav1.FieldsV1) (s fieldpath.Set, err error)

FieldsToSet creates a set paths from an input trie of fields

func NewCRDVersionConverter

func NewCRDVersionConverter(t TypeConverter, o runtime.ObjectConvertor, h schema.GroupVersion) merge.Converter

NewCRDVersionConverter builds a VersionConverter for CRDs from a TypeConverter and an ObjectConvertor.

func NewConflictError

func NewConflictError(conflicts merge.Conflicts) *errors.StatusError

NewConflictError returns an error including details on the requests apply conflicts

func NewPathElement

func NewPathElement(s string) (fieldpath.PathElement, error)

NewPathElement parses a serialized path element

func NewVersionConverter

NewVersionConverter builds a VersionConverter from a TypeConverter and an ObjectConvertor.

func PathElementString

func PathElementString(pe fieldpath.PathElement) (string, error)

PathElementString serializes a path element

func RemoveObjectManagedFields

func RemoveObjectManagedFields(obj runtime.Object)

RemoveObjectManagedFields removes the ManagedFields from the object before we merge so that it doesn't appear in the ManagedFields recursively.

func SetToFields

func SetToFields(s fieldpath.Set) (f metav1.FieldsV1, err error)

SetToFields creates a trie of fields from an input set of paths


type AtMostEvery

type AtMostEvery struct {
	// contains filtered or unexported fields

AtMostEvery will never run the method more than once every specified duration.

func NewAtMostEvery

func NewAtMostEvery(delay time.Duration) *AtMostEvery

NewAtMostEvery creates a new AtMostEvery, that will run the method at most every given duration.

func (*AtMostEvery) Do

func (s *AtMostEvery) Do(fn func()) bool

Do will run the method if enough time has passed, and return true. Otherwise, it does nothing and returns false.

type DeducedTypeConverter

type DeducedTypeConverter struct{}

DeducedTypeConverter is a TypeConverter for CRDs that don't have a schema. It does implement the same interface though (and create the same types of objects), so that everything can still work the same. CRDs are merged with all their fields being "atomic" (lists included).

Note that this is not going to be sufficient for converting to/from CRDs that have a schema defined (we don't support that schema yet). TODO(jennybuckley): Use the schema provided by a CRD if it exists.

func (DeducedTypeConverter) ObjectToTyped

func (DeducedTypeConverter) ObjectToTyped(obj runtime.Object) (*typed.TypedValue, error)

ObjectToTyped converts an object into a TypedValue with a "deduced type".

func (DeducedTypeConverter) TypedToObject

func (DeducedTypeConverter) TypedToObject(value *typed.TypedValue) (runtime.Object, error)

TypedToObject transforms the typed value into a runtime.Object. That is not specific to deduced type.

type ManagedInterface

type ManagedInterface interface {
	// Fields gets the fieldpath.ManagedFields.
	Fields() fieldpath.ManagedFields

	// Times gets the timestamps associated with each operation.
	Times() map[string]*metav1.Time

ManagedInterface groups a fieldpath.ManagedFields together with the timestamps associated with each operation.

func DecodeObjectManagedFields

func DecodeObjectManagedFields(from []metav1.ManagedFieldsEntry) (ManagedInterface, error)

DecodeObjectManagedFields extracts and converts the objects ManagedFields into a fieldpath.ManagedFields.

func NewEmptyManaged

func NewEmptyManaged() ManagedInterface

NewEmptyManaged creates an empty ManagedInterface.

func NewManaged

NewManaged creates a ManagedInterface from a fieldpath.ManagedFields and the timestamps associated with each operation.

type TypeConverter

type TypeConverter interface {
	ObjectToTyped(runtime.Object) (*typed.TypedValue, error)
	TypedToObject(*typed.TypedValue) (runtime.Object, error)

TypeConverter allows you to convert from runtime.Object to typed.TypedValue and the other way around.

func NewTypeConverter

func NewTypeConverter(models proto.Models, preserveUnknownFields bool) (TypeConverter, error)

NewTypeConverter builds a TypeConverter from a proto.Models. This will automatically find the proper version of the object, and the corresponding schema information.
