Unreleased

0.2.1 - 2026-10-03

Changed

  • Requires Mutare 0.5 ({:mutare, "~> 0.5.0"}).

0.2.0 - 2026-09-26

Changed

  • Mutare 0.4.1 or newer is required ({:mutare, "~> 0.4.1"}). Mutare now hands a piped args |> MyWorker.new(opts) to the enqueue family as the direct call it is sugar for, so both spellings are matched by one path; the mutants, their variants and their notes are unchanged.

0.1.0 - 2026-09-07

Initial release.

Added

  • Mutare.Oban.WorkerReturn (:oban_worker_return) — swaps perform/1 return values for other valid Oban returns (:ok/{:ok, v} → {:error, :mutare}; {:error, reason} → :ok / {:cancel, reason}; {:cancel, reason} → {:error, reason} / :ok; {:snooze, s} → :ok; legacy {:discard, reason} → :ok / {:cancel, reason} and bare :discard → :ok). Applies only inside Oban.Worker / Oban.Pro.Worker modules, including branch tails via return_replacements. Declares required_modules/0, so a run where Oban is not loadable fails at startup with a Mutare.EnvironmentError.
  • Mutare.Oban.Enqueue (:oban_enqueue) — rewrites MyWorker.new(args, opts) enqueue options (direct, aliased, or piped): max_attempts: n → 1 (n ≠ 1), and drops unique:, schedule_in:, and scheduled_at:.
  • Report notes on every mutant describing assertions that could detect the changed behaviour.
  • Ignore-variant labels on both families, so # mutare:ignore[oban_worker_return:ok] / # mutare:ignore[oban_enqueue:unique] can suppress one kind of mutant.
  • Mutare.Oban.all/0 for splicing both families into a :mutators list.
