示例1: getStoreList

// getStoreList returns a store list matching the required attributes.
// Results are cached for performance.
//
// If it cannot retrieve a StoreDescriptor from the Store's gossip, it
// garbage collects the failed key.
//
// TODO(embark, spencer): consider using a reverse index map from
// Attr->stores, for efficiency. Ensure that entries in this map still
// have an opportunity to be garbage collected.
func (a *allocator) getStoreList(required proto.Attributes) *storeList {
	if a.storeLists == nil {
		a.storeLists = map[string]*storeList{}
	}
	key := required.SortedString()
	if sl, ok := a.storeLists[key]; ok {
		return sl
	}
	sl := &storeList{}
	a.storeLists[key] = sl

	updateStoreList := func(key string) {
		storeDesc, err := storeDescFromGossip(key, a.gossip)
		if err != nil {
			// We can no longer retrieve this key from the gossip store,
			// perhaps it expired.
			delete(a.capacityKeys, key)
		} else if required.IsSubset(*storeDesc.CombinedAttrs()) {
			sl.Add(storeDesc)
		}
	}

	if a.deterministic {
		var keys []string
		for key := range a.capacityKeys {
			keys = append(keys, key)
		}
		sort.Strings(keys)
		for _, key := range keys {
			updateStoreList(key)
		}
		return sl
	}

	for key := range a.capacityKeys {
		updateStoreList(key)
	}
	return sl
}
