how to find memory leak

1. Simple use of memory leaks and malloc debug libraries for C and C + + programs under Ccmalloc-linux and Solaris. 2. dmalloc-debug Malloc Library. 3. Electric Fence-linux the malloc () debug library written by Bruce Perens in the distribution release. 4. leaky-linux detects a memory leak under the program. 5. Trace and analyze

initialization succeeds, but the operation is out of bounds, such as adding one to the operation of the array, char a [5] = "Hello", causing a segment error, without taking into account the ' \ S ' storage space, the program may not be affected if the memory space of the cross-border access is idle. If the space is already occupied, if illegal operation is performed, the program may collapse. (4) Forgetting to release

This article was reproduced from: http://blog.chinaunix.net/uid-26859697-id-5758037.htmlAfter analyzing the Kmemleak implementation, test it as usual to determine the function is normal.As with Kmemcheck, this feature needs to be enabled in case the kernel is turned on. The main configuration items are: Config_debug_kernel, Config_have_debug_kmemleak, Config_debug_kmemleak, and the config_debug_kmemleak_ of the number of configuration information record bars Early_log_size, usually the number of

) a good test tool. In the development of the memory leak can not be completely avoided, the key is to find a memory leak when the use of good testing tools to quickly locate the problem. There are several professional tools on the market to check the Java

: Number of objectsMemory Leak Detection Tool (VLD)Tools1:https://vld.codeplex.com/releases2:http://pan.baidu.com/s/1gd7vqndAfter the installation is complete, projects created using Visual Studio will default to include the VLD header file directory.And the runtime in the Bin directory has been automatically added to the path variable.All we need to do is include Here, I manually created a memory

Test a business data portal for functional testing of the Task manager, found that the IE process has reached the 423,145k, suspected of a memory leak, so I intend to use IE plug-in JS memory leaks dector to detect, However, after some operations that could cause memory leaks, the test results were always normal and no

leaks is an all-manual process, which is described in detail in the Raizlabs Wrang Dalvik series article. Here are a few key steps: Learn about OutOfMemoryError by bugsnag,crashlytics or developer console and other statistical platforms. Reproduce the problem. To reproduce the problem, the model is important because some problems only occur on specific devices. In order to find a specific model, you need to do everything possible, you ma

idea is to repeat a certain operation, to see that there is no significant growth in the existence, and no recovery. Normal application will be stable in a small range, the problem of the application is generally continuous growth, very difficult to recover. Two tools, one is a manual refresh, one is the active refresh, compared to the author recommended the first method. Manual control, feel better. Discovering that there is a memory

memory leak point. What if we can find log information about our own classes in many blocks? We can search for the keyword "helloworldscene. cpp" to locate the memory leakage Block in the HelloWorld scenario. We can find the following log information: ---------- Block 1153

Where multiple memory leaks were encountered during WPF application development using Openexpressapp , a memory leak problem was approached in the previous article "WPF unknown memory leak reason, hair is white a few root", This article will share with you how to solve this

i = 0; i Mobjs[i] = new Object ();}Finish ();}});Activitymanager.instance (). registactivity (this);}@Overrideprotected void OnDestroy () {Super.ondestroy ();}} The memory leaks in the case are artificially constructed, so we already knew there was a leak, but the actual development process, the memory leak is hidden,

?? In the previous article several cases of Android memory leak were mentioned in the development of memory leaks common, but too hasty. Since the beginning of the year, the work has not yet formally started, I looked at GitHub open source Square leakcanary, and the company's project test environment to practiced hand, trying to

Objectivemany people think Java programs , because there is a garbage collection mechanism, there should be no memory leaks. In fact, if we no longer use an object in a program, but because there is still a reference to it, the garbage collector cannot reclaim it, and of course the memory used by the object cannot be consumed, which results in a memory
