Hi guys!

I’m trying to upgrade the current library for phoenix socket client for elixir itself https://github.com/Aircloak/phoenix_gen_socket_client, which is more than a year old and works for 1.3, but has several outdated things, like Poison dependency, cowboy, among others, and i can’t fix the tests.

It creates a generic base phoenix app, but fails to launch the endpoint:

     ** (EXIT from #PID<0.265.0>) shutdown: failed to start child: Phoenix.PubSub.PG2
         ** (EXIT) shutdown: failed to start child: Phoenix.PubSub.LocalSupervisor
             ** (EXIT) an exception was raised:
                 ** (ArgumentError) argument error
                     (stdlib) :ets.new(TestSite.Endpoint, [:set, :named_table, {:read_concurrency, true}])
                     (phoenix_pubsub) lib/phoenix/pubsub/local_supervisor.ex:24: Phoenix.PubSub.LocalSupervisor.init/1
                     (stdlib) supervisor.erl:295: :supervisor.init/1
                     (stdlib) gen_server.erl:374: :gen_server.init_it/2
                     (stdlib) gen_server.erl:342: :gen_server.init_it/6
                     (stdlib) proc_lib.erl:249: :proc_lib.init_p_do_apply/3

The weird thing is that i run on iex :ets.new(TestSite.Endpoint, [:set, :named_table, {:read_concurrency, true}]) and runs ok

this is the declaration of the testSite:

defmodule TestSite do
  @moduledoc false

  defmodule PubSub do
    @moduledoc false
    def start_link(), do: Registry.start_link(keys: :duplicate, name: TestSite.PubSub)

    def subscribe(subscriber_key), do: Registry.register(__MODULE__, subscriber_key, nil)

    def notify(subscriber_key, message) do
      __MODULE__
      |> Registry.lookup(subscriber_key)
      |> Enum.map(fn {pid, _value} -> pid end)
      |> Enum.each(&send(&1, message))
    end
  end

  defmodule Endpoint do
    @moduledoc false
    use Phoenix.Endpoint, otp_app: :phoenix_gen_socket_client

    socket("/test_socket", TestSite.Socket, websocket: true, longpoll: false)
    socket("/test_socket_updated", TestSite.SocketUpdated, websocket: true, longpoll: false)

    @doc false
    def init(:supervisor, config) do
      {:ok,
       Keyword.merge(
         config,
         https: false,
         http: [port: 29_876],
         secret_key_base: String.duplicate("abcdefgh", 8),
         debug_errors: false,
         server: true,
         pubsub: [adapter: Phoenix.PubSub.PG2, name: __MODULE__]
       )}
    end
  end
...

any clues?
