When I use IEx.pry
or a breakpoint (via :int.break()
), the shell dies too quickly, and I only have ~10 seconds before I lose my session:
`** (EXIT from #PID<0.606.0>) shell process exited with reason: shutdown`
And 10 seconds isn’t enough to productively debug my code in the shell/debugger. My best guess is that there’s a default timeout in a :supervisor.child_spec
that I need to override, but I’m not 100% sure.
This is what I’ve tried so far (and why they haven’t worked so far):
- Increase the :timeout parameter to :infinity in the child_specs to Supervisor.start_link() in
MyApp.Application
. - Updated the cowboy idle_timeout because Observer indicated that my request is a cowboy process. I don’t think it’s likely that it’s cowboy, though. If the default is 60s, I’m not even getting close to 60s.
- Instead of using IEx.pry, I tried using the debugger (via
:ni.break
) - Just noting that I can’t use
mix test --trace
, which sets the timout to:infinity
– I’m trying to debug an Endpoint action (not a test)
How do people use the debugger/IEx.pry? Are people just not encountering the 10s timeout like I am? Or is there a common configuration that I’m not using?
My application.ex
in case it helps:
defmodule MyApp.Application do
use Application
def start(_type, _args) do
children = [
MyApp.Repo,
{MyApp.Web.Endpoint, [timeout: :infinity]},
{Phoenix.PubSub, [name: MyApp.PubSub, adapter: Phoenix.PubSub.PG2]},
{MyApp.Middleware.Ets.AnEtsThing, [name: MyApp.Middleware.Ets.AnEtsThing, table_name: :my_app_config_2]},
]
opts = [strategy: :one_for_one, name: MyApp.Supervisor]
Supervisor.start_link(children, opts)
end
def config_change(changed, _new, removed) do
MyApp.Web.Endpoint.config_change(changed, removed)
:ok
end
end
