Functions

func GenerateSystemUniqueListenerAddresses

func GenerateSystemUniqueListenerAddresses() (string, string)

GenerateSystemUniqueListenerAddresses is a function that returns two listener addresses with unique ports per system and should be used to overwrite rpctest's default generator which is prone to use colliding ports.

func NextAvailablePort

func NextAvailablePort() int

NextAvailablePort returns the first port that is available for listening by a new node, using a lock file to make sure concurrent access for parallel tasks on the same system don't re-use the same port.
