Description
Implementation of ConnectionHandler
While connection manager responsibility is to keep track of resources:
sockets and threads running connection and their state changes (including
changes imposed by ConnectionHandler, e.g. weather a uni- or duplex- data
flow was negotiated), the responsibility of ConnectionHandler is to:
- run handshake protocol on the underlying bearer
- start mux
ConnectionHandler is run on each inbound or outbound connection and returns
Handle. Upon successful handshake negotiation it returns all the
necessary information to run mini-protocols. Note that it is not responsible
for running them: that's what a server does or p2p-governor by means of
PeerStateActions.

data Handle (muxMode ∷ MuxMode) peerAddr versionData bytes m a b Source #
States of the connection handler thread.
MuxRunning- successful Handshake, mux startedHandleHandshakeClientError- the connection handler thread was running client side
of the handshake negotiation, which failed with
a
HandshakeException HandleHandshakeServerError- the connection handler thread was running server side of the
handshake protocol, which fail with
HandshakeException HandleError- the multiplexer thrown
MuxError.

To be used as makeConnectionHandler field of ConnectionManagerArguments.
Note: We need to pass MiniProtocolBundle what forces us to have two
different ConnectionManagers: one for `node-to-client` and another for
`node-to-node` connections. But this is ok, as these resources are
independent.
type MuxConnectionManager muxMode socket peerAddr versionData versionNumber bytes m a b = ConnectionManager muxMode socket peerAddr (Handle muxMode peerAddr versionData bytes m a b) (HandleError muxMode versionNumber) m Source #
Type alias for ConnectionManager using Handle.
tracing
data ConnectionHandlerTrace versionNumber versionData Source #
ConnectionHandlerTrace is embedded into ConnectionManagerTrace with
ConnectionHandlerTrace
constructor. It already includes ConnectionId so we don't need to take
care of it here.
TODO: when Handshake will get its own tracer, independent of Mux, it
should be embedded into ConnectionHandlerTrace.
