Help upgrading phoenix socket client lib to phoenix 1.4

This probably means the endpoint is already started, or that there is at least an :ets table with that name already:

iex(1)> :ets.new(TestSite.Endpoint, [:set, :named_table, {:read_concurrency, true}])
TestSite.Endpoint
iex(2)> :ets.new(TestSite.Endpoint, [:set, :named_table, {:read_concurrency, true}])
** (ArgumentError) argument error
    (stdlib) :ets.new(TestSite.Endpoint, [:set, :named_table, {:read_concurrency, true}])

Maybe that helps point you in the right direction?

I checked ets tables right before start, and there’s no table with that name:

the endpoint:

  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
      IO.inspect(:ets.all |> Enum.filter(fn x -> is_atom(x) end))
      {: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

the test results:

If i remove the init() it doesn’t start at all.
Would be that Endpoint.start_link() isn’t the right way to start the endpoint without a supervisor anymore?

any other hint?

Ah so for one thing, in a test, use start_supervised(Endpoint). This will ensure that the endpoint is shut down in the given test case before it is started in another test case. Can you show where you’re calling start_link right now?

same thing with start_supervised(Endpoint)

This is where it’s being called at Phoenix.Channels.GenSocketClientTest

  setup_all do
    ExUnit.CaptureLog.capture_log(fn -> Endpoint.start_link() end)
    #start_supervised(Endpoint)
    :ok
  end

this is the repo and the test file that i’m working on right now
