Constants

const (
	// Field indicates that the content of this path element is a field's name
	Field = "f"

	// Value indicates that the content of this path element is a field's value
	Value = "v"

	// Index indicates that the content of this path element is an index in an array
	Index = "i"

	// Key indicates that the content of this path element is a key value map
	Key = "k"

	// Separator separates the type of a path element from the contents
	Separator = ":"
)

Variables

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("{}")}

Functions

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 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 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

Types

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 GvkParser

type GvkParser struct {
	// contains filtered or unexported fields
}

GvkParser contains a Parser that allows introspecting the schema.

func NewGVKParser

func NewGVKParser(models proto.Models, preserveUnknownFields bool) (*GvkParser, error)

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

func (*GvkParser) Type

func (p *GvkParser) Type(gvk schema.GroupVersionKind) *typed.ParseableType

Type returns a helper which can produce objects of the given type. Any errors are deferred until a further function is called.

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 DecodeManagedFields

func DecodeManagedFields(encodedManagedFields []metav1.ManagedFieldsEntry) (ManagedInterface, error)

DecodeManagedFields converts ManagedFields from the wire format (api format) to the format used by sigs.k8s.io/structured-merge-diff

func NewEmptyManaged

func NewEmptyManaged() ManagedInterface

NewEmptyManaged creates an empty ManagedInterface.

func NewManaged

func NewManaged(f fieldpath.ManagedFields, t map[string]*metav1.Time) ManagedInterface

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