Functions ¶

func IsDirWriteable ¶

func IsDirWriteable(dir string) error

IsDirWriteable checks if dir is writable by writing and removing a file to dir. It returns nil if dir is writable.

func Preallocate ¶

func Preallocate(f *os.File, sizeInBytes int) error

Preallocate tries to allocate the space for given file. This operation is only supported on linux by a few filesystems (btrfs, ext4, etc.). If the operation is unsupported, no error will be returned. Otherwise, the error encountered will be returned.

func PurgeFile ¶

func PurgeFile(dirname string, suffix string, max uint, interval time.Duration, stop <-chan struct{}) <-chan error

func ReadDir ¶

func ReadDir(dirpath string) ([]string, error)

ReadDir returns the filenames in the given directory in sorted order.

type Lock ¶

type Lock interface {
	Name() string
	TryLock() error
	Lock() error
