编写自己的内存管理器 [英] Write your own memory manager

问题描述

我想写我自己的内存管理器。目标语言是C ++，内存管理器的目标主要是帮助调试。它应该检测双重释放，内存覆盖等。当然 - 我想了解内存管理。

有人可以给我一个提示，因此我可以学习如何编写这样的内存管理器的资源？ / p>

感谢您的帮助。

解决方案

非常有趣的项目，你可能从中学到很多。这里有一点关于内存管理主题的阅读材料。它讨论了内存管理的一些基础知识，引入一个简单的malloc实现，然后介绍几个更高级的主题。

内部内存管理

此外，由于您提到您希望做一个有用的调试内存管理器，你可能想考虑由Memcheck / Valgrind（Linux的一个奇妙的内存调试器）的开发人员阅读本文。它详细说明了它们如何跟踪memchck中的所有元数据（无论特定字节是否被定义，初始化等）。这是一个有点详细，但它是如何使一个可扩展和高效的动态内存检查器的良好的阅读。

如何影响程序使用的每个字节的内存

I'd like to write my own memory manager. The target language is C++ and the goal of the memory manager is mainly to help debugging. It should detect double frees, memory overwrite and so on. And of course - I'd like to learn about memory management.

Can someone give me a hint so resources where I can learn how to write such a memory manager?

Thank you for your help.

解决方案

I think this is a very interesting project that you might learn a lot from. Here's a little bit of reading material on the subject of memory management. It goes over some of the basics of memory management, leads into a simple malloc implementation, then touches on a couple more advanced topics.

Inside memory management

Also, since you mention that you want to make a memory manager that is useful for debugging, you may want to consider reading this paper by the developers of Memcheck/Valgrind (A wonderful memory debugger for Linux). It details how they track all the the metadata (whether or not a particular byte is defined, intialized, etc.) in memchck. It's a bit detailed, but it's good reading on how to make a scalable and efficient dynamic memory checker.
