Hint from Phoenix 1.4.17, which has a connect/7 shim:
lib/phoenix/socket/transport.ex:
def connect(endpoint, handler, _transport_name, transport, serializers, params, _pid \\ self()) do
IO.warn "Phoenix.Socket.Transport.connect/7 is deprecated"
handler.connect(%{
endpoint: endpoint,
transport: transport,
options: [serializer: serializers],
params: params
})
end
