Unknown dialyzer warning option: race_conditions with OTP 25.0.4

[gabrielpedepera]

Environment

Elixir & Erlang/OTP versions (elixir --version):

Erlang/OTP 25 [erts-13.0.4] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]
Elixir 1.14.0 (compiled with Erlang/OTP 25)

Which version of Dialyxir are you using? (cat mix.lock | grep dialyxir):

"dialyxir": {:hex, :dialyxir, "1.2.0", "58344b3e87c2e7095304c81a9ae65cb68b613e28340690dfe1a5597fd08dec37", [:mix], [{:erlex, ">= 0.2.6", [hex: :erlex, repo: "hexpm", optional: false]}], "hexpm", "61072136427a851674cab81762be4dbeae7679f85b1272b6d25c3a839aff8463"},

Current behavior

To demostraste this behaviour I have create an application through the command mix new dummy_app and having mix.exs with dialyxir like that:

defmodule DummyApp.MixProject do
  use Mix.Project

  def project do
    [
      app: :dummy_app,
      version: "0.1.0",
      elixir: "~> 1.14",
      start_permanent: Mix.env() == :prod,
      dialyzer: dialyzer(),
      deps: deps()
    ]
  end

  # Run "mix help compile.app" to learn about applications.
  def application do
    [
      extra_applications: [:logger]
    ]
  end

  # Run "mix help deps" to learn about dependencies.
  defp deps do
    [
      {:dialyxir, "~> 1.1", only: [:dev, :test], runtime: false}
      # {:dep_from_hexpm, "~> 0.3.0"},
      # {:dep_from_git, git: "https://github.com/elixir-lang/my_dep.git", tag: "0.1.0"}
    ]
  end

  defp dialyzer do
    [
      plt_file: {:no_warn, "priv/plts/dialyzer.plt"},
      flags: [:error_handling, :underspecs, :race_conditions],
      plt_add_apps: [:mix],
      ignore_warnings: "dialyzer.ignore-warnings"
    ]
  end
end

as feedback of the command mix dialyzer I got the error :dialyzer.run error: Unknown dialyzer warning option: race_conditions

Expected behavior

If I change to using OTP 24 instead I'm able to run the dialyzer successfully

Yes OTP removed support for this feature. I don't think there is really anything we can do other than remove it from the documentation.

erlang/otp#5502

[gabrielpedepera]

Thanks for the info @jeremyjh . I haven't checked. Do you want some help to remove these references from the documentation?

[jeremyjh]

Sure, a PR is welcome!

[gabrielpedepera]

Thanks one more time @jeremyjh.. I'm closing this issue.
