Functions

func LoggedErrorStack

func LoggedErrorStack(err error) error

LoggedErrorStack is a developer helper function that will cause the error stack of the error to be printed out at error severity if and only if the "log-error-stack" feature flag has been specified. The passed in error is also the return value of this function.

func NetworkOperationWitDefaultRetries

func NetworkOperationWitDefaultRetries(networkOp func() error, description string) func() error

NetworkOperationWithDefaultRetries calls the supplied function and if it returns a network error which is temporary, will retry a number of times before giving up. A default attempt strategy is used.

func NetworkOperationWithRetries

func NetworkOperationWithRetries(strategy utils.AttemptStrategy, networkOp func() error, description string) func() error

NetworkOperationWithRetries calls the supplied function and if it returns a network error which is temporary, will retry a number of times before giving up.

func RunCommand

func RunCommand(cmd string, args ...string) error
