什么是 Windows 7 的容错堆? [英] What is Windows 7's Fault Tolerant Heap?

问题描述

我想要一些关于它如何工作的技术信息，以及如何禁用或枚举与经常崩溃的进程相关联的容错堆垫片.Windows 7 是否使用某种启发式方法来决定何时应用 FTH 填充程序?

I'd like some technical information on how it works, and how I can disable or enumerate the Fault Tolerant Heap shims that are associated with processes that crash frequently. Is there a heuristic of some sort that Windows 7 uses to decide when to apply an FTH shim?

推荐答案

Fault Tolerant Heap 是堆之上的一层，用于防御常见的堆错误，例如堆溢出、双重释放等.据我所知，只有一个 FTH 垫片 - 每个缓解措施都不是多个.http://msdn.microsoft.com/en-us/library/dd744764(VS.85).aspx 描述了如何通过事件日志监控应用程序是否启用了 FTH.

Fault Tolerant Heap is a layer over the heap that defends against common heap errors, such as heap overruns, double frees, and so on. To my knowledge, there is only one FTH shim - not multiple for each mitigation. http://msdn.microsoft.com/en-us/library/dd744764(VS.85).aspx describes how you can monitor if FTH is being enabled for an application via the event log.

我不相信 MS 已经发布了启用 FTH 的确切启发式方法，但是是的，有一种启发式方法.

I don't believe MS has published the exact heuristic that will enable the FTH, but yes, there is a heuristic.
