func CopyFile ¶

func CopyFile(src, dst string, fsync bool) (int64, error)

func CreateDirs ¶

func CreateDirs(dirs ...string) error

func FirstExistingFile ¶

func FirstExistingFile(filepaths ...string) string

func GetLSNFromDeltaFilename ¶

func GetLSNFromDeltaFilename(filename string) (dbutils.LSN, error)

func Retry ¶

func Retry(fn func() (bool, error), numberOfAttempts int, timeBetweenAttempts time.Duration, totalTimeout time.Duration) error

Retry retries a given function until either it returns true, which indicates success, or the number of attempts reach the limit, or the global timeout is reached. The cool-off period between attempts is passed as well. The cancellation should generally be handled outside of either this function. In other words, if total time is set to a significantly large value, there should be an external mechanism to terminate the routine to be retried with an error.

func SyncFileAndDirectory ¶

func SyncFileAndDirectory(fp *os.File) error

func TableDir ¶

func TableDir(oid dbutils.OID) string
