Elixir v1.15 new app changes

[josevalim]

Once phx_new is ready to depend on Elixir v1.15+, we should change config :logger, :console to config :logger, :default_formatter in the generated config files.

[yordis]

@josevalim which file would that be at?

@yordis Files:

• phoenix/installer/templates/phx_single/config/config.exs

  Line 57 in bd3ce36

  config :logger, :console,

• phoenix/installer/templates/phx_single/config/dev.exs

  Line 59 in bd3ce36

  config :logger, :console, format: "[$level] $message\n"

[yordis]

Found the reference in terms of how it suppose to be!

config :logger, :default_formatter,
  format: "[$level] $message $metadata\n",
  metadata: [:error_code, :file]

Thank you, @michallepicki. I needed clarification!

would this explain why upgrading to 1.15, I am starting to see 404 route errors

Ranch listener AppWeb.Endpoint.HTTP, connection process #PID<0.51084.0>, stream 3 had its request process #PID<0.51807.0> exit with reason {{%Phoenix.Router.NoRouteError{plug_status: 404,

those never showed until we moved to elixir 1.15 and OTP 26. Also using Phx 1.6 (trying to upgrade to 1.7 but not as trivial this time)

[epinault]

also it seems that we need more than that.

config :logger, :default_handler,
  level: :info

need to be set as the level is only set from the handler per

All previous console configuration, except for :level, now go under :default_formatter.

[josevalim]

You can still set config :logger, level: .... There is a global and a per-handler configuration.

yes I see that it s not solving my issue . something in the upgrade is causing the logger to show raised error still , I filed #5628 to track it separately at this point.
