Algumas tarefas relacionadas a ativos são executadas durante a inicialização do aplicativo

Estava me perguntando… existe uma tarefa rake que podemos executar para fazer esse gerenciamento de plugin em vez de fazê-lo durante a inicialização da aplicação? Executamos nossas instâncias com AppArmor e gostaríamos de evitar permitir que o servidor de aplicação escreva arquivos da aplicação.

Isso vai exigir alterações aqui

github.com/discourse/discourse

lib/plugin/instance.rb

58d6ee36e


      
          File.delete(js_file_path) if js_asset_exists?
          
          if contents.present?
            contents.insert(0, "<%")
            contents << "%>"
            write_asset(js_file_path, contents.join("\n"))
          end

Estamos excluindo incondicionalmente um arquivo para plugins que definem ativos JS na inicialização do plugin. Acho que poderíamos fazer isso na pasta tmp em vez disso.

por que não como parte da tarefa rake de ativos normal?

Não sou contra a alteração, pelo que sei. É assim principalmente por razões históricas; seria uma mudança bastante complexa.
