Functions

func CheckTimeout added in v2.1.2 

func CheckTimeout(ctx context.Context, err error) error

func DialSocket 

func DialSocket(ctx context.Context, socketName string, opts ...grpc.DialOption) (*grpc.ClientConn, error)

DialSocket dials the given socket and returns the resulting connection

func DisplayVersion 

func DisplayVersion() string

DisplayVersion returns a printable version for `telepresence`

func GetConfigFile added in v2.3.5 

func GetConfigFile(c context.Context) string

GetConfigFile gets the path to the configFile as stored in filelocation.AppUserConfigDir

func GetExe 

func GetExe() string

GetExe returns the name of the running executable

func GetInstallMechanism added in v2.4.8 

func GetInstallMechanism() (string, error)

GetInstallMechanism returns how the executable was installed on the machine.

func GetMechanismFromPath added in v2.4.8 

func GetMechanismFromPath(execPath string) (string, error)

GetMechanismFromPath is a helper function that contains most of the logic required for GetInstallMechanism, but enables us to test it since we can control the path passed in.

func ListenSocket added in v2.4.0 

func ListenSocket(ctx context.Context, processName, socketName string) (net.Listener, error)

ListenSocket returns a listener for the given socket and returns the resulting connection

func RemoveSocket added in v2.4.0 

func RemoveSocket(listener net.Listener) error

RemoveSocket removes any representation of the the socket from the filesystem.

func Retry 

func Retry(c context.Context, text string, f func(context.Context) error, durations ...time.Duration) error

Retry will run the given function repeatedly with an increasing delay until it returns without error.

The function takes 0 to 2 durations with the following meaning 

Delay - initial delay, i.e. the delay between the first and the second call.
MaxDelay - maximum delay between calling the functions (delay will never grow beyond this value)

func RunError 

func RunError(err error) error

RunError checks if the given err is a *exit.ExitError, and if so, extracts Stderr and the ExitCode from it.

func SetConfig added in v2.4.0 

func SetConfig(ctx context.Context, configDir, configYml string) (context.Context, error)

func SetDefaultConfig added in v2.4.0 

func SetDefaultConfig(ctx context.Context, configDir string) (context.Context, error)

SetDefaultConfig creates a config that has the registry set correctly. This ensures that the config on the machine of whatever is running the test, isn't used, which could cause conflict with the tests.

func SetExe 

func SetExe(executable string)

SetExe defines the name of the executable (for testing purposes only)

func SocketExists(name string) (bool, error)

SocketExists returns true if a socket is found with the given name

func WaitUntilSocketAppears(name, path string, ttw time.Duration) error

WaitUntilSocketAppears waits until the socket at the given path comes into existence and returns when that happens. The wait will be max ttw (time to wait) long. An error is returned if that time is exceeded before the socket is removed.

func WaitUntilSocketVanishes 

func WaitUntilSocketVanishes(name, path string, ttw time.Duration) error

WaitUntilSocketVanishes waits until the socket at the given path is removed and returns when that happens. The wait will be max ttw (time to wait) long. An error is returned if that time is exceeded before the socket is removed.
