示例1: addStore

// AddStore creates a new store on the same Transport but doesn't create any ranges.
func (m *multiTestContext) addStore() {
	idx := len(m.stores)
	var clock *hlc.Clock
	if len(m.clocks) > idx {
		clock = m.clocks[idx]
	} else {
		clock = m.clock
		m.clocks = append(m.clocks, clock)
	}
	var eng engine.Engine
	var needBootstrap bool
	if len(m.engines) > idx {
		eng = m.engines[idx]
	} else {
		eng = engine.NewInMem(proto.Attributes{}, 1<<20)
		m.engines = append(m.engines, eng)
		needBootstrap = true
		// Add an extra refcount to the engine so the underlying rocksdb instances
		// aren't closed when stopping and restarting the stores.
		// These refcounts are removed in Stop().
		if err := eng.Open(); err != nil {
			m.t.Fatal(err)
		}
	}

	stopper := stop.NewStopper()
	ctx := m.makeContext(idx)
	store := storage.NewStore(ctx, eng, &proto.NodeDescriptor{NodeID: proto.NodeID(idx + 1)})
	if needBootstrap {
		err := store.Bootstrap(proto.StoreIdent{
			NodeID:  proto.NodeID(idx + 1),
			StoreID: proto.StoreID(idx + 1),
		}, stopper)
		if err != nil {
			m.t.Fatal(err)
		}

		// Bootstrap the initial range on the first store
		if idx == 0 {
			if err := store.BootstrapRange(nil); err != nil {
				m.t.Fatal(err)
			}
		}
	}
	if err := store.Start(stopper); err != nil {
		m.t.Fatal(err)
	}
	store.WaitForInit()
	m.stores = append(m.stores, store)
	if len(m.senders) == idx {
		m.senders = append(m.senders, kv.NewLocalSender())
	}
	m.senders[idx].AddStore(store)
	// Save the store identities for later so we can use them in
	// replication operations even while the store is stopped.
	m.idents = append(m.idents, store.Ident)
	m.stoppers = append(m.stoppers, stopper)
}
