刚刚将Devise（和Omniauth）集成到我们的网站中，替换了我们最初使用的从零开始的登录系统。
一切进展顺利，并且omniauth与Twitter和Facebook一起使用，但是由于某些原因，当我单击登录按钮时，rails完全锁定。
仅当我强制退出使用时，该过程才会结束sudo killall -KILL ruby。试图通过Ctrl+C关闭终端窗口或运行常规kill命令来终止进程是徒劳的。
挂起后，我进入了活动监视器并对该过程进行了采样。它显示了以下内容：

根据第一个线程的末尾，似乎bcrypt可能是问题所在。我真的不知道如何解释这一点。
引用的文件和行在这里：https : //github.com/rg3/bcrypt/blob/master/crypt_blowfish/crypt_blowfish.c#L649
它看起来像是对外部二进制文件的引用，因此就诊断问题而言，我不知道从何而来。
一些帮助理解这一点以及有关可能原因的任何信息将不胜感激:)
编辑：实际上，似乎它没有挂起。只花了31.1分钟...

在这一点上，我有点困惑。我认为它可能仍然需要花费很长时间，但是我看不出发生这种情况的任何原因。
好的，这是一个相当简单的配置错误。
本质上，我只是将bcrypt复杂度级别设置得太高。该计算是2^x其中x代表的复杂程度。
我最初的设置是：
config.stretches = Rails.env.test? ? 1 : 25
默认值为10。因为我不知道该数字的指数性质，所以我没有意识到这会有多大的区别。
我现在将其设置为13:)
