Functions

func CreateJournals

func CreateJournals(c *gc.C, bk *Broker, specs ...*pb.JournalSpec)

CreateJournals using the Broker Apply API, and wait for them to be allocated.

func Journal

func Journal(spec pb.JournalSpec) *pb.JournalSpec

Journal returns |spec| after applying reasonable test defaults for fields which are not already set.

Types

type Broker

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

Broker is a lightweight, embedded Gazette broker suitable for testing client functionality which depends on the availability of the Gazette service.

func NewBroker

func NewBroker(c *gc.C, etcd *clientv3.Client, zone, suffix string) *Broker

NewBroker returns a ready Broker with the given Context. Note that journals must still be created with CreateJournal before use.

func (*Broker) AllocateIdleCh

func (b *Broker) AllocateIdleCh() <-chan struct{}

AllocateIdleCh signals when the Broker's Allocate loop took an action, such as updating a journal assignment, and has since become idle.

func (*Broker) Client

func (b *Broker) Client() pb.JournalClient

Client of the test Broker.

func (*Broker) RevokeLease

func (b *Broker) RevokeLease(c *gc.C)

RevokeLease of the Broker, allowing its Allocate loop to immediately exit.

func (*Broker) WaitForExit

func (b *Broker) WaitForExit()

WaitForExit of the test Broker Allocate loop, and complete its teardown. WaitForExit will block indefinitely if the Broker's Journal limit is not also zeroed (and another Broker takes over), or its lease revoked.

func (*Broker) ZeroJournalLimit

func (b *Broker) ZeroJournalLimit(c *gc.C)

ZeroJournalLimit of the Broker. The test Broker will eventually exit, assuming other Broker(s) are available to take over the assignments.
