Hi…
I am registering two workers for my application supervision tree:
defmodule SamlyHowto.Application do
use Application
# See https://hexdocs.pm/elixir/Application.html
# for more information on OTP Applications
def start(_type, _args) do
import Supervisor.Spec
# Define workers and child supervisors to be supervised
children = [
# Start the endpoint when the application starts
supervisor(SamlyHowtoWeb.Endpoint, []),
# Start your own worker by calling: SamlyHowto.Worker.start_link(arg1, arg2, arg3)
# worker(SamlyHowto.Worker, [arg1, arg2, arg3]),
worker(Samly.Provider, [], [id: Fed1]),
worker(Samly.Provider, [], [id: Fed2]),
]
# See https://hexdocs.pm/elixir/Supervisor.html
# for other strategies and supported options
opts = [strategy: :one_for_one, name: SamlyHowto.Supervisor]
Supervisor.start_link(children, opts)
end
# Tell Phoenix to update the endpoint configuration
# whenever the application is updated.
def config_change(changed, _new, removed) do
SamlyHowtoWeb.Endpoint.config_change(changed, removed)
:ok
end
end
Samly.Provider defines their start_link function like this:
def start_link(gs_opts \\ []) do
GenServer.start_link(__MODULE__, [], gs_opts)
end
As per the docs, I thought they should have been named Fed1 and Fed2… I have also tried the following (adding name):
worker(Samly.Provider, [], [id: Fed1, name: Fed1]),
worker(Samly.Provider, [], [id: Fed2, name: Fed2])
The examples on this page suggests that “name” should do the job:
But here there is no mention of “name” being an option here:
https://hexdocs.pm/elixir/Supervisor.Spec.html#worker/3
When I run observer.start() the registered name doesn’t appear (however I can see the numbered processes) there OR even when I run Process.registered() from IEX there is no mention of the name, but the app launches ok…
