The report gives information about ways to detect bugs, methodology of static analysis, correct and incorrect use of analysis tools. The author also provides...
In my previous article I wrote that I don't like the approach of evaluating the efficiency of static analyzers with the help of synthetic tests. In that article, I give the example of a code fragment that the analyzer treats as a special case, and deliberately doesn't issue a warning for. To be honest, I didn't expect such an overflow of comments regarding the fact that an analyzer may not issue warnings because of the mechanisms of false positive elimination. In general the topic of battling against false positives is such a huge part of any static analyzer that it's really not clear what we can discuss here; but still, let's talk about it. Such mechanisms exist not only in our analyzer but also in another analyzers/compilers. Nevertheless, if this topic brought about so much discussion, I think it's worth talking about, and so I wrote this explanatory article.
This article will demonstrate that during the development of large projects static analysis is not just a useful, but a completely necessary part of the development process. This article is the first one in a series of posts, devoted to the ability to use PVS-Studio static analyzer to improve the quality and reliability of the Tizen operating system. For a start, I checked a small part of the code of the operating system (3.3%) and noted down about 900 warnings pointing to real errors. If we extrapolate the results, we will see that our team is able to detect and fix about 27000 errors in Tizen. Using the results of the conducted study, I made a presentation for the demonstration to the Samsung representatives with the offers about possible cooperation. The meeting was postponed, that is why I decided not to waste time and transform the material of the presentation to an article. Get some coffee and cookies, as there is a long programmer thriller waiting for us.
If you have any questions regarding the PVS-Studio static code analyzer or its licensing terms, please contact me at [email protected]. I'll be happy to assist you with running the analyzer on your project and setting it up. If capabilities of a demo version are insufficient for you, I'll generate a temporary license key so that you can discover all the features of our analyzer in detail. Anyway, do not hesitate to contact me. To solve any technical questions, I'll involve experienced programmers from our team. Together we can solve any difficulties.
I've recently read a promo article about a static C/C++ analyzer called PVS Studio by viva64.com, where the readers were urged to use the product, and I did just that. Evgeniy Ryzhkov, the creator of the program kindly sent me a one-week key, and I immediately started testing some of my C/XS code.
C and C++ programmers tend to make mistakes when writing code.
Many of these mistakes can be found using -Wall, asserts, tests, meticulous code review, IDE warnings, building with different compilers for different operating systems running on different hardware configurations, and the like. But even all these means combined often fail to reveal all the bugs. Static code analysis helps improve the situation a little. In this post, we will take a look at some static analysis tools.
