Websocket Rails死鎖問題

在導致死鎖錯誤的Rails 4應用程序中出現問題（詳情如下）。我使用'websocket-rails'寶石。Websocket Rails死鎖問題

這似乎是發生在每2要求，從dispatcher = new WebSocketRails('localhost:3000/websocket');來（從我的應用程序的前端）

我見過的很少，除了王菲內舊的問題沒有提及這個問題的回購在GitHub上：https://github.com/faye/faye/issues/190

錯誤：

添加

config.middleware.delete Rack::Lock

到application.rb應該有所幫助。

到目前爲止好！我以爲我曾經在某處讀過我不需要這樣做，因爲我的應用程序是 - 一直是 - 一個Rails 4應用程序。有關這條線如何解決我的問題的快速解釋？ – paulruescher 2014-10-20 08:47:52

那麼，這裏是一個非常小的討論：https：//github.com/websocket-rails/websocket-rails/issues/119（順便說一句，你也可以啓用'config.threadsafe！'代替）。 – bodrovis 2014-10-20 08:52:29

我也寫了一篇關於Faye的文章，也許會有一些有趣的事情給你：http://www.sitepoint.com/realtime-mini-chat-rails-faye/ – bodrovis 2014-10-20 08:52:57
