Visual C++ - Memory Leak Detection

由 让人想犯罪 __ 提交于 2019-12-17 18:10:14
问题 Any suggestions? This SO post talks about Visual Leak Detector, but I'm looking for other tools. Also, please don't recommend this. 回答1: I've used Visual Leak Detector quite recently and it works pretty well. It's very simple to build it in (just include vld.h ) and doesn't require any instrumentation. I found that I needed to write a couple of scripts though to parse the output into something more useful for my purposes (it is crying out for a decent GUI). Note the new website -- the project

Memory leak using pandas dataframe

由 感情迁移 提交于 2019-12-17 16:35:32
问题 I am using pandas.DataFrame in a multi-threaded code (actually a custom subclass of DataFrame called Sound ). I have noticed that I have a memory leak, since the memory usage of my program augments gradually over 10mn, to finally reach ~100% of my computer memory and crash. I used objgraph to try tracking this leak, and found out that the count of instances of MyDataFrame is going up all the time while it shouldn't : every thread in its run method creates an instance, makes some calculations,

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 months ago . In Python 2 there's a couple of tools but everything seems to be old and out-of-dated. I've found PySizer and Heapy but everything seems to be Python2 oriented and would take a lot of effort to port. objgraph is interesting but still not a fully working profiler Which tool are using ? 回答1: Pympler is a Python

Why can't objgraph capture the growth of np.array()?

由 柔情痞子 提交于 2019-12-12 14:48:15
问题 See the code: import objgraph import numpy as np objgraph.show_growth() j = 20 y = [] for i in range(5): for l in range(j): y.append(np.array([np.random.randint(500),np.random.randint(500)])) print 'i:',i objgraph.show_growth() print '___' #objgraph.show_most_common_types(limit=100) j += 1 the result is: i: 1 wrapper_descriptor 1596 +3 weakref 625 +1 dict 870 +1 method_descriptor 824 +1 i: 2 i: 3 i: 4 For the 2,3 and 4 epoch, it shows nothing growing. But it should show that the number of

How to do memory check on a daemon program?

由 做~自己de王妃 提交于 2019-12-09 05:34:31
问题 I have written a C++ application, that runs forever until terminated manually. It monitors other important applications. As a result my Daemon application should not go down. Keeping that in mind, I want to see if there are any memory leaks in my application. I used valgrind but since this application keeps running forever the valgrind does not exit. if I do a control - C then I don't get complete info from the valgrind logfile. Is there a tool that can do what Valgrind does? 回答1: I believe

I have the following warning in Tomcat 8.5 I'm not sure I can ignore WARNING [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [AppName] appears to have started a thread named [pool-20-thread-1] but has failed to stop it. This is very likely to create a memory leak.
