LeakCanary: simple and crude memory leak detection tool, leakcanary Leak Detection Almost every programmer may experience memory leakage during development. How can we detect memory leakage in the app? Square introduces LeakCanary, a simple and crude tool for detecting memory leaks. What is memory leakage? Memory leaka

Original: https://vld.codeplex.com/Visual Leak Detector is a memory leak detection tool dedicated to Visual C + +, which is free, open source, and highly robust.VLD is easy to use:1. After installing VLD, just tell Visual C + + where to find its header files and libraries. (: https://vld.codeplex.com)2. You can then use VLD by adding the following line of code to

. the only exception is stdafx. H (or any other precompiled header ). a precompiled header, such as stdafx. h, must always be the first header encoded in a source file, so VLD. h must be encoded ded after any precompiled headers.2. if your program contains one or more DLLs that you wowould also like to check for memory leaks, then also include VLD. h in at least one source file from each DLL to be removed ded in leak

, such as stdafx. H and so on, you can also put the pre-compiled header file stdafx. h, and introduce the pre-compiled header file in the source file, the VLD. h can be introduced in multiple source files or common header files, for example, in. H and B. VLD is introduced in H. h. Multiple source files introduce. H and B. h, there is only one VLD in the process. H code, without any side effects (only for version 1.9d, other versions are unknown ). In addition, the parameter meanings under VLD.

program ends, scan the shared map to obtain the unreleased information. When we put the map into the shared memory and use the c ++ standard library, we need to implement a shared memory-based allocator by ourselves, replace the default map allocator, and implement the map memory allocation scheme in this allocator. Can also use boost library 1.35 or later), it adds a library called boost: interprocess, refer to the http://blog.cong.co/stl-alloc.html for details5) how to use this tool?The Memor

Compared with other memory leak detection tools, it detects memory leaks and has the following features:1. You can obtain the call stack of the memory leak point. If you can, you can also obtain the fil

First we need to know if the program has a memory leak, and then locate which line of code is leaking memory so that it can be repaired. The simplest method of course is the use of professional testing tools, more famous such as Boundscheck, the function is very strong, I believe that people do C + + development can not be separated from it. In addition, you do not use any of the tools, but to implement the memory

Currently, an application that analyzes real-time traffic is developed in Linux, and a memory leak is found in the program during a joint test.This is anxious, will soon be on-line, fortunately found a valgrind tool, the perfect solution to the problem of memory leaks.Recommend you can use to see.Valgrind is a set of simulation-based program debugging and analysis tools running on Linux, and its main author is Julian Seward, who won the Google-o ' Rei
