Functions

func BestKnownPath

func BestKnownPath() (string, error)

BestKnownPath returns the best known fsrepo path. If the ENV override is present, this function returns that value. Otherwise, it returns the default repo path.

func ConfigAt

func ConfigAt(repoPath string) (*config.Config, error)

ConfigAt returns an error if the FSRepo at the given path is not initialized. This function allows callers to read the config file even when another process is running and holding the lock.

func Init

func Init(repoPath string, conf *config.Config) error

Init initializes a new FSRepo at the given path with the provided config. TODO add support for custom datastores.

func IsInitialized

func IsInitialized(path string) bool

IsInitialized returns true if the repo is initialized at provided |path|.

func LockedByOtherProcess

func LockedByOtherProcess(repoPath string) bool

LockedByOtherProcess returns true if the FSRepo is locked by another process. If true, then the repo cannot be opened by this process.

func Open added in v0.3.2

func Open(repoPath string) (repo.Repo, error)

Open the FSRepo at path. Returns an error if the repo is not initialized.

func Remove

func Remove(repoPath string) error

Remove recursively removes the FSRepo at |path|.

Datastore returns a repo-owned datastore. If FSRepo is Closed, return value is undefined.

func (*FSRepo) GetConfigKey

func (r *FSRepo) GetConfigKey(key string) (interface{}, error)
