var (
	// ErrCouldNotExtract occurs when an extraction fails.
	ErrCouldNotExtract = errors.New("utils: could not extract the archive")

	// ErrExtractedFileTooBig occurs when a file to extract is too big.
	ErrExtractedFileTooBig = errors.New("utils: could not extract one or more files from the archive: file too big")
)

Functions ¶

func CleanURL ¶

func CleanURL(str string) string

CleanURL removes all parameters from an URL

func CompareStringLists ¶

func CompareStringLists(X, Y []string) []string

CompareStringLists returns the strings which are present in X but not in Y

func Contains ¶

func Contains(needle string, haystack []string) bool

Contains looks for a string into an array of strings and returns whether the string exists

func Exec ¶

func Exec(dir string, bin string, args ...string) ([]byte, error)

Exec runs the given binary with arguments

func Hash ¶

func Hash(str string) string

Hash returns an unique hash of the given string

func SelectivelyExtractArchive ¶

func SelectivelyExtractArchive(r io.Reader, toExtract []string, maxFileSize int64) (map[string][]byte, error)

SelectivelyExtractArchive extracts the specified files and folders from targz data read from the given reader and store them in a map indexed by file paths

Types ¶

type Stopper ¶

type Stopper struct {
	// contains filtered or unexported fields
}

Stopper eases the graceful termination of a group of goroutines

func NewStopper ¶

func NewStopper() *Stopper

NewStopper initializes a new Stopper instance

func (*Stopper) Begin ¶

func (s *Stopper) Begin()

Begin indicates that a new goroutine has started.

func (*Stopper) Chan ¶

func (s *Stopper) Chan() chan struct{}

Chan returns the channel on which goroutines could listen to determine if they should stop. The channel is closed when Stop() is called.

func (*Stopper) End ¶

func (s *Stopper) End()

End indicates that a goroutine has stopped.

func (*Stopper) Sleep ¶

func (s *Stopper) Sleep(d time.Duration) bool

Sleep puts the current goroutine on sleep during a duration d Sleep could be interrupted in the case the goroutine should stop itself, in which case Sleep returns false.

func (*Stopper) Stop ¶

func (s *Stopper) Stop()

Stop asks every goroutine to end.
