Functions ¶
func ListenerPipe ¶ added in v1.2.0
ListenerPipe returns a full-duplex in-memory connection, like net.Pipe. Unlike net.Pipe one end of the connection is returned as an object satisfying the net.Listener interface. The first call to the Accept method of this object will return a net.Conn connected to the other net.Conn returned by ListenerPipe. Any subsequent calls to Accept will block until the listener is closed.
Types ¶

Client represents a debugger service client. All client methods are synchronous.
type Config ¶
type Config struct { // Debugger configuration object, used to configure the underlying // debugger used by the server. Debugger debugger.Config // Listener is used to serve requests. Listener net.Listener // ProcessArgs are the arguments to launch a new process. ProcessArgs []string // AcceptMulti configures the server to accept multiple connection. // Note that the server API is not reentrant and clients will have to coordinate. AcceptMulti bool // APIVersion selects which version of the API to serve (default: 1). APIVersion int // CheckLocalConnUser is true if the debugger should check that local // connections come from the same user that started the headless server CheckLocalConnUser bool // DisconnectChan will be closed by the server when the client disconnects DisconnectChan chan<- struct{} }
Config provides the configuration to start a Debugger and expose it with a service.
Only one of ProcessArgs or AttachPid should be specified. If ProcessArgs is provided, a new process will be launched. Otherwise, the debugger will try to attach to an existing process with AttachPid.
type RPCCallback ¶
type RPCCallback interface { Return(out interface{}, err error) // SetupDoneChan returns a channel that should be closed to signal that the // asynchronous method has completed setup and the server is ready to // receive other requests. SetupDoneChan() chan struct{} // DisconnectChan returns a channel that should be closed to signal that // the client that initially issued the command has been disconnected. DisconnectChan() chan struct{} }
RPCCallback is used by RPC methods to return their result asynchronously.
