Functions

func IsTcpMultiaddr

func IsTcpMultiaddr(a ma.Multiaddr) bool

func IsUtpMultiaddr

func IsUtpMultiaddr(a ma.Multiaddr) bool

func ReuseErrShouldRetry

func ReuseErrShouldRetry(err error) bool

ReuseErrShouldRetry diagnoses whether to retry after a reuse error. if we failed to bind, we should retry. if bind worked and this is a real dial error (remote end didnt answer) then we should not retry.

func ReuseportIsAvailable

func ReuseportIsAvailable() bool

reuseportIsAvailable returns whether reuseport is available to be used. This is here because we want to be able to turn reuseport on and off selectively. For now we use an ENV variable, as this handles our pressing need:

IPFS_REUSEPORT=false ipfs daemon

If this becomes a sought after feature, we could add this to the config. In the end, reuseport is a stop-gap.
