Rails i18n 方法导致分段错误？
Rails i18n method results in segmentation fault?
我有一个名为 "StoryPresenter" 的 class，它充当我的模型对象的包装器（class 的一个实例，称为 "Story"）并帮助呈现模型的数据我的意见。 StoryPresenter 的实例包含故事的实例，以及以下方法：
def state
if story.school_state_territory.blank?
""
else
" | #{ story.school_state_territory }"
end
end
上述方法工作正常，但是当我添加 Rails i18n 方法并刷新浏览器时，我的 Rails 服务器崩溃了：
def state
if story.school_state_territory.blank?
""
else
" | #{ t(story.school_state_territory) }"
end
end
崩溃后，当我重新启动服务器并刷新浏览器时 i18n 方法仍然存在，页面加载但我看到 HTML 在en.yml 文件中缺少指示给定属性的翻译关键字的页面。预计会出现警告或类似的东西（因为密钥实际上丢失了），但我不希望在这种情况下 Rails 服务器崩溃。
发生崩溃后，我在服务器日志中看到以下输出：
Started GET "/stories/drafts" for ::1 at 2016-06-28 10:48:42 -0400

我看到 "Kern_Invalid_Address" 异常代码，这与崩溃的原因有关吗？

来自评论：
通过替换找到了解决方法（不是底层错误的解决方案）：
" | #{ t(story.school_state_territory) }"
有：
" | #{ t(story.school_state_territory) rescue "" }"
似乎来自 t 的未处理异常导致了导致崩溃的连锁反应。
Ruby 使用 longjmp 在 C 中实现异常，这意味着代码执行链停止并且永远不会 return 到它的原始位置。
在实现服务器时，执行链通常以所谓的 "event loop" 或反应器模式循环。
如果 longjmp 跳出此循环，服务器可能（并且很可能会）崩溃或挂起。
这类似于 Ruby 代码，当不处理任何异常时，将跳回堆栈顶部并可能终止进程 (return)。
因此，在从 C 实现 Ruby 回调时，保护回调不受任何 longjmp 或 Ruby 异常的影响通常很重要。 Ruby MRI为此提供了CAPI（即rb_protect）。
这同样适用于 FFI。使用 FFI 时，重要的是 "wrap" 在 rescue 语句中进行回调，然后再将它们传递给采用回调的 FFI 函数。
找到回调处理程序（无论是服务器调用 Ruby 来处理请求，还是另一个库，例如后台任务库）并提交错误报告会很有帮助。
我有一个名为 "StoryPresenter" 的 class，它充当我的模型对象的包装器（class 的一个实例，称为 "Story"）并帮助呈现模型的数据我的意见。 StoryPresenter 的实例包含故事的实例，以及以下方法：
def state
if story.school_state_territory.blank?
""
else
" | #{ story.school_state_territory }"
end
end
上述方法工作正常，但是当我添加 Rails i18n 方法并刷新浏览器时，我的 Rails 服务器崩溃了：
def state
if story.school_state_territory.blank?
""
else
" | #{ t(story.school_state_territory) }"
end
end
崩溃后，当我重新启动服务器并刷新浏览器时 i18n 方法仍然存在，页面加载但我看到 HTML 在en.yml 文件中缺少指示给定属性的翻译关键字的页面。预计会出现警告或类似的东西（因为密钥实际上丢失了），但我不希望在这种情况下 Rails 服务器崩溃。
发生崩溃后，我在服务器日志中看到以下输出：

来自评论：
通过替换找到了解决方法（不是底层错误的解决方案）：
" | #{ t(story.school_state_territory) }"
有：
" | #{ t(story.school_state_territory) rescue "" }"
似乎来自 t 的未处理异常导致了导致崩溃的连锁反应。
Ruby 使用 longjmp 在 C 中实现异常，这意味着代码执行链停止并且永远不会 return 到它的原始位置。
在实现服务器时，执行链通常以所谓的 "event loop" 或反应器模式循环。
如果 longjmp 跳出此循环，服务器可能（并且很可能会）崩溃或挂起。
这类似于 Ruby 代码，当不处理任何异常时，将跳回堆栈顶部并可能终止进程 (return)。
因此，在从 C 实现 Ruby 回调时，保护回调不受任何 longjmp 或 Ruby 异常的影响通常很重要。 Ruby MRI为此提供了CAPI（即rb_protect）。
这同样适用于 FFI。使用 FFI 时，重要的是 "wrap" 在 rescue 语句中进行回调，然后再将它们传递给采用回调的 FFI 函数。
找到回调处理程序（无论是服务器调用 Ruby 来处理请求，还是另一个库，例如后台任务库）并提交错误报告会很有帮助。
