Functions ¶

func BasicSignalHandler ¶

func BasicSignalHandler(l *log.Entry) chan struct{}

func CopyDir ¶

func CopyDir(src string, dst string) (err error)

CopyDir recursively copies a directory tree, attempting to preserve permissions. Source directory must exist, destination directory must *not* exist. Symlinks are ignored and skipped.

func CopyFile ¶

func CopyFile(src, dst string) (err error)

CopyFile copies the contents of the file named src to the file named by dst. The file will be created if it does not already exist. If the destination file exists, all it's contents will be replaced by the contents of the source file. The file mode will be copied from the source and the copied data is synced/flushed to stable storage.

func DuplicateMapBool ¶

func DuplicateMapBool(base map[string]bool) map[string]bool

func Expand ¶

func Expand(path string) (string, error)

func IndexOfString ¶

func IndexOfString(slice []string, str string) int

func ListParameters ¶

func ListParameters(out io.Writer, keys []string, varMaps []map[string]string)

func MakeShutdownCh ¶

func MakeShutdownCh() <-chan struct{}

func MergeMaps ¶

func MergeMaps(base map[string]interface{}, m ...map[string]interface{}) map[string]interface{}

func MergeMapsBool ¶

func NetworkOverlap ¶

func NetworkOverlap(netCIDRs []*net.IPNet) error

func NewCancellationContext ¶
