func ConfigureTransport added in v0.1.3

func ConfigureTransport(tr *http.Transport, proto, addr string) error

ConfigureTransport configures the specified Transport according to the specified proto and addr. If the proto is unix (using a unix socket to communicate) or npipe the compression is disabled.

func DialPipe added in v0.1.3

func DialPipe(_ string, _ time.Duration) (net.Conn, error)

DialPipe connects to a Windows named pipe. This is not supported on other OSes.

func DialerFromEnvironment added in v0.2.0

func DialerFromEnvironment(direct *net.Dialer) (proxy.Dialer, error)

DialerFromEnvironment takes in a "direct" *net.Dialer and returns a proxy.Dialer which will route the connections through the proxy using the given dialer.

func GetProxyEnv added in v0.2.0

func GetProxyEnv(key string) string

GetProxyEnv allows access to the uppercase and the lowercase forms of proxy-related variables. See the Go specification for details on these variables.

func NewTCPSocket

func NewTCPSocket(addr string, tlsConfig *tls.Config) (net.Listener, error)

NewTCPSocket creates a TCP socket listener with the specified address and the specified tls configuration. If TLSConfig is set, will encapsulate the TCP listener inside a TLS one.

func NewUnixSocket

func NewUnixSocket(path string, gid int) (net.Listener, error)

NewUnixSocket creates a unix socket with the specified path and group.


type InmemSocket added in v0.1.3

type InmemSocket struct {
	// contains filtered or unexported fields

InmemSocket implements net.Listener using in-memory only connections.

func NewInmemSocket added in v0.1.3

func NewInmemSocket(addr string, bufSize int) *InmemSocket

NewInmemSocket creates an in-memory only net.Listener The addr argument can be any string, but is used to satisfy the `Addr()` part of the net.Listener interface

func (*InmemSocket) Accept added in v0.1.3

func (s *InmemSocket) Accept() (net.Conn, error)

Accept implements the Accept method in the Listener interface; it waits for the next call and returns a generic Conn.

func (*InmemSocket) Addr added in v0.1.3

func (s *InmemSocket) Addr() net.Addr

Addr returns the socket's addr string to satisfy net.Listener

func (*InmemSocket) Close added in v0.1.3

func (s *InmemSocket) Close() error

Close closes the listener. It will be unavailable for use once closed.

func (*InmemSocket) Dial added in v0.1.3

func (s *InmemSocket) Dial(network, addr string) (net.Conn, error)
