Open3 を使用して perl スクリプトを呼び出す Ruby on Rails アプリケーションを作成しています。ただし、perl スクリプトを呼び出すと、アプリで Timeout::Error が必要以上に早く発生し続けます。スクリプトを呼び出すコードは次のようになります。
Timeout::timeout(120){
@stdout, @stderr, @exit_code = Open3.capture3(@command)
[@exit_code.to_i, @stdout, @stderr]
}
「長時間」実行される可能性のあるスクリプト (おそらく 20 ～ 30 秒) を呼び出すことは、Ruby on Rails アプリケーションにとって理想的ではないことを認識していますが、選択肢はあまりありません。
ユニコーンを使用して同時実行性を取得しており、ユニコーンのタイムアウトを 60 秒に設定しています。ユニコーン ファイルの 60 秒のタイムアウトと、Open3 呼び出しにラップされた 120 秒のタイムアウトにもかかわらず、私の要求は約 18 秒でタイムアウトし続けます。反対側に結果が表示されているため、スクリプトが正常に終了していることはわかっていますが、アプリがスクリプトの戻りを待つ必要があります。
Rails アプリを強制的に待機させ、タイムアウトさせない他の方法はありますか?
ありがとう！
