Functions

func CleanAndExpandPath 

func CleanAndExpandPath(path string) string

CleanAndExpandPath expands environment variables and leading ~ in the passed path, cleans the result, and returns it. This function is taken from https://github.com/btcsuite/btcd

func ClientAddressDialer 

func ClientAddressDialer(defaultPort string) func(context.Context,
	string) (net.Conn, error)

ClientAddressDialer creates a gRPC dialer that can also dial unix socket addresses instead of just TCP addresses.

func EnforceSafeAuthentication 

func EnforceSafeAuthentication(addrs []net.Addr, macaroonsActive,
	tlsActive bool) error

EnforceSafeAuthentication enforces "safe" authentication taking into account the interfaces that the RPC servers are listening on, and if macaroons and TLS is activated or not. To protect users from using dangerous config combinations, we'll prevent disabling authentication if the server is listening on a public interface.

func GetPostgresConfigKVDB 

func GetPostgresConfigKVDB(cfg *sqldb.PostgresConfig) *postgres.Config

GetPostgresConfigKVDB converts a sqldb.PostgresConfig to a kvdb postgres.Config.

func GetSqliteConfigKVDB 

func GetSqliteConfigKVDB(cfg *sqldb.SqliteConfig) *sqlite.Config

GetSqliteConfigKVDB converts a sqldb.SqliteConfig to a kvdb sqlite.Config.

func IsDevBuild 

func IsDevBuild() bool

IsDevBuild returns a bool to indicate whether we are in a development environment.

NOTE: always return false here.

func IsLoopback 

func IsLoopback(host string) bool

IsLoopback returns true if an address describes a loopback interface.

func IsPrivate 

func IsPrivate(addr net.Addr) bool

IsPrivate returns true if the address is private. The definitions are, 

https://en.wikipedia.org/wiki/Link-local_address
https://en.wikipedia.org/wiki/Multicast_address
Local IPv4 addresses, https://tools.ietf.org/html/rfc1918
Local IPv6 addresses, https://tools.ietf.org/html/rfc4193

func IsUnix 

func IsUnix(addr net.Addr) bool

IsUnix returns true if an address describes an Unix socket address.

func ListenOnAddress 

func ListenOnAddress(addr net.Addr) (net.Listener, error)

func NormalizeAddresses 

func NormalizeAddresses(addrs []string, defaultPort string,
	tcpResolver TCPResolver) ([]net.Addr, error)

NormalizeAddresses returns a new slice with all the passed addresses normalized with the given default port and all duplicates removed.

func NormalizeNetwork 

func NormalizeNetwork(network string) string

NormalizeNetwork returns the common name of a network type used to create file paths. This allows differently versioned networks to use the same path.

func ParseAddressString 

func ParseAddressString(strAddress string, defaultPort string,
	tcpResolver TCPResolver) (net.Addr, error)

ParseAddressString converts an address in string format to a net.Addr that is compatible with lnd. UDP is not supported because lnd needs reliable connections. We accept a custom function to resolve any TCP addresses so that caller is able control exactly how resolution is performed.

func ParseHexColor 

func ParseHexColor(colorStr string) (color.RGBA, error)

ParseHexColor takes a hex string representation of a color in the form "#RRGGBB", parses the hex color values, and returns a color.RGBA struct of the same color.

The <pubkey> must be presented in hex, and result in a 33-byte, compressed public key that lies on the secp256k1 curve. The <addr> may be any address supported by ParseAddressString. If no port is specified, the defaultPort will be used. Any tcp addresses that need resolving will be resolved using the custom TCPResolver.

func TLSListenOnAddress 

func TLSListenOnAddress(addr net.Addr,
	config *tls.Config) (net.Listener, error)

TLSListenOnAddress creates a TLS listener that listens on the given address.

func Validate 

func Validate(validators ...Validator) error

Validate accepts a variadic list of Validators and checks that each one passes its Validate method. An error is returned from the first Validator that fails.
