阅读更多关于 What is Dynamic Code Analysis?

问题 What is Dynamic Code Analysis? How is it different from Static Code Analysis (ie, what can it catch that can't be caught in static)? I've heard of bounds checking and memory analysis - what are these? What other things are checked using dynamic analysis? -Adam 回答1: Simply put, static analysis collect information based on source code and dynamic analysis is based on the system execution , often using instrumentation. Advantages of dynamic analysis Is able to detect dependencies that are not

Android: Differntiate running Apps from other processes in android

阅读更多关于 Android: Differntiate running Apps from other processes in android

问题 I did run ps command in shell on my phone. The question is how can I differentiate processes related to applications which I executed as a normal phone user such as Google Play, Adobe Reader and etc.? As I noticed some processes are run by user names in format app_xxx and as childs of process zygote however there are plenty of them which include background services and system services. Are there any method to make a short-list of them like the list my phone displays when i press app list

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 years ago . I often find myself spending a lot of time figuring out why certain SUM()-aggregates sum up wrongly in SQL-queries. This problem often occurs if I do not take care when adding a JOIN, resulting in duplicate values being summed up etc. If I work with a big query with lots of JOINs, nested subqueries, GROUP BYs

iOS project: Static/Dynamic code analysis and call graphs

阅读更多关于 iOS project: Static/Dynamic code analysis and call graphs

问题 I am looking for some handy code analysis tools for iOS projects, esp. to do static analysis, dynamic analysis and generate call graphs. In my investigation so far, I found Dtrace as explained here and here Clang as explained here Doxygen as explained here Are there any other open source tools available for my case that I miss? Also has anyone tried any of the above ones successfully for objective-c iOS projects? Thanks 回答1: Are you not satisfied yet with the built-in XCode analyzer (Product

Tools for finding Shared Mutable data bugs in Java

阅读更多关于 Tools for finding Shared Mutable data bugs in Java

问题 I have a large legacy system to maintain. The codebase uses threads all over the place and those threads share a lot of mutable data. I know, sounds bad. Anyway, don't answer "rewrite the whole application from scratch" or I'll vote you down :-) I have tried to run some static analysis tools on the codebase, but none of those seem to catch this case which occurs a lot in our source code: multiple threads are reading and writing variables which are not marked as volatile or synchronized at all

static and dynamic code analysis

阅读更多关于 static and dynamic code analysis

I found several questions about this topic, and all of them with lot of references, but still I don't have a clear idea about that, because most of the references speak about concrete tools and not about the concept in general of the analysis. Thus I have some questions: About Static analysis: 1. I would like to have a reference, or a summary of which techniques are successful and have more relevance nowadays. 2. What really can they do about discovering bugs, can we make a summary or it is depending of the tool? About symbolic execution: 1. Where could be enclose symbolic execution? I guess
