func PollFunc

func PollFunc(clockSource *fakeclock.FakeClock, f func() error) error

PollFunc is like PollFuncWithTimeout with timeout=10s.

func PollFuncWithTimeout

func PollFuncWithTimeout(clockSource *fakeclock.FakeClock, f func() error, timeout time.Duration) error

PollFuncWithTimeout is used to periodically execute a check function, it returns error after timeout.

func ProposeValue

func ProposeValue(t *testing.T, raftNode *TestNode, time time.Duration, nodeID ...string) (*api.Node, error)

ProposeValue proposes a value to a raft test cluster

func ShutdownNode

func ShutdownNode(node *TestNode)

ShutdownNode shuts down a raft test node and deletes the content of the state directory

func TeardownCluster

func TeardownCluster(t *testing.T, nodes map[uint64]*TestNode)

TeardownCluster destroys a raft cluster used for tests

func WaitForCluster

func WaitForCluster(t *testing.T, clockSource *fakeclock.FakeClock, nodes map[uint64]*TestNode)

WaitForCluster waits until leader will be one of specified nodes

func WaitForPeerNumber

func WaitForPeerNumber(t *testing.T, clockSource *fakeclock.FakeClock, nodes map[uint64]*TestNode, count int)

WaitForPeerNumber waits until peers in cluster converge to specified number

Types

type SimpleKeyRotator

type SimpleKeyRotator struct {
	raft.EncryptionKeys
	// contains filtered or unexported fields
}

SimpleKeyRotator does some DEK rotation

func NewSimpleKeyRotator

func NewSimpleKeyRotator(keys raft.EncryptionKeys) *SimpleKeyRotator

NewSimpleKeyRotator returns a basic EncryptionKeyRotator

func (*SimpleKeyRotator) GetKeys

func (s *SimpleKeyRotator) GetKeys() raft.EncryptionKeys

GetKeys returns the current set of keys

func (*SimpleKeyRotator) NeedsRotation

func (s *SimpleKeyRotator) NeedsRotation() bool

NeedsRotation returns whether we need to rotate

func (*SimpleKeyRotator) QueuePendingKey

func (s *SimpleKeyRotator) QueuePendingKey(key []byte)

QueuePendingKey lets us rotate the key

func (*SimpleKeyRotator) RotationNotify

func (s *SimpleKeyRotator) RotationNotify() chan struct{}

RotationNotify returns the rotation notification channel

func (*SimpleKeyRotator) SetNeedsRotation

func (s *SimpleKeyRotator) SetNeedsRotation(override *bool)

SetNeedsRotation enables you to inject a value for NeedsRotation

func (*SimpleKeyRotator) SetUpdateFunc

func (s *SimpleKeyRotator) SetUpdateFunc(updateFunc func() error)

SetUpdateFunc enables you to inject an error when updating keys

func (*SimpleKeyRotator) UpdateKeys

func (s *SimpleKeyRotator) UpdateKeys(newKeys raft.EncryptionKeys) error

UpdateKeys updates the current encryption keys

type TestNode

type TestNode struct {
	*raft.Node
	Server         *grpc.Server
	Listener       *WrappedListener
	SecurityConfig *ca.SecurityConfig
	Address        string
	StateDir       string

	KeyRotator *SimpleKeyRotator
	// contains filtered or unexported fields
}

TestNode represents a raft test node

func CopyNode

func CopyNode(t *testing.T, clockSource *fakeclock.FakeClock, oldNode *TestNode, forceNewCluster bool, kr *SimpleKeyRotator) (*TestNode, context.Context)

CopyNode returns a copy of a node

func Leader

func Leader(nodes map[uint64]*TestNode) *TestNode

Leader determines who is the leader amongst a set of raft nodes belonging to the same cluster

func NewInitNode

func NewInitNode(t *testing.T, tc *cautils.TestCA, raftConfig *api.RaftConfig, opts ...raft.NodeOptions) (*TestNode, *fakeclock.FakeClock)

NewInitNode creates a new raft node initiating the cluster for other members to join

func NewJoinNode

func NewJoinNode(t *testing.T, clockSource *fakeclock.FakeClock, join string, tc *cautils.TestCA, opts ...raft.NodeOptions) *TestNode
