type Controller 

type Controller struct {

) (waitForChanges bool, err error)

NOTE: the Execution may be updated by the controller several times during execution.

type ExecConfig struct {

	// Execution is the current state of the execution.
	// NOTE: value_set and result are set to nil.
	Execution *execution.Execution `protobuf:"bytes,1,opt,name=execution,proto3" json:"execution,omitempty"`
	// Target is the current target to execute.
	// This is the value of the TargetRef in execution.

type Lease 

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

Lease renews one granted claim and cancels its operation ClaimClockSkew before the last committed expiry. Renewal and settlement stop permanently on a stale epoch. Reclaim cannot overlap operation when the reclaimer's clock lead plus operation's cancellation drain time stays within ClaimClockSkew.

func NewLease 

func NewLease(le *logrus.Entry, expiry time.Time, duration time.Duration, renew func(context.Context, time.Time) error) *Lease

NewLease constructs a lease for one granted claim with duration greater than ClaimClockSkew. renew must honor cancellation and report success only after the new expiry commits. Construction and Execute require an already granted claim.

func (*Lease) Execute 

func (l *Lease) Execute(rctx context.Context, operation func(context.Context) error) error

Execute runs and drains operation under the committed lease. A failed or blocked renewal cannot delay cancellation past expiry minus ClaimClockSkew. Losing the lease returns nil so a routine does not restart the same claim. Execute joins renewal before returning; renew must honor its context.
