示例1: initDefaultDatastore

func initDefaultDatastore(repoPath string, conf *config.Config) error {
	// The actual datastore contents are initialized lazily when Opened.
	// During Init, we merely check that the directory is writeable.
	leveldbPath := path.Join(repoPath, leveldbDirectory)
	if err := dir.Writable(leveldbPath); err != nil {
		return fmt.Errorf("datastore: %s", err)
	}

	flatfsPath := path.Join(repoPath, flatfsDirectory)
	if err := dir.Writable(flatfsPath); err != nil {
		return fmt.Errorf("datastore: %s", err)
	}
	return nil
}

示例2: Init

// Init initializes a new FSRepo at the given path with the provided config.
// TODO add support for custom datastores.
func Init(repoPath string, conf *config.Config) error {

	// packageLock must be held to ensure that the repo is not initialized more
	// than once.
	packageLock.Lock()
	defer packageLock.Unlock()
