  • Checking Oracle VM VirtualBox. Part 1

    19.09.2014
    Virtual machines are used for very different tasks. Personally I have been using VirtualBox for many years to test software and simply study various Linux distributions. And now, after years of using the tool and encountering unexpected behavior every now and then, I've decided to make use of my experience in analysis of open-source projects and check the source code of Oracle VM Virtual Box.

  • Overlapping Between PVS-Studio and Cppcheck

    15.09.2014
    We have been asked many times about the degree of overlapping between diagnostics of our PVS-Studio analyzer and the Cppcheck analyzer. I've decided to write a small article about it to refer to as a quick answer in future. To put it brief, the overlapping is very little – only 6% of the total number of errors is detected by both analyzers. In this article, I will tell you how we got this figure. Read more
  • Valgrind: Good but Not Enough

    10.09.2014
    Not so long ago we tried to demonstrate the benefit of using the PVS-Studio static analyzer to one company. We failed, but while corresponding with them, I prepared a detailed answer about the static and dynamic analysis methodologies. Now I've decided to publish this answer in the form of a small article. I think the readers will find it interesting, and I also will be able to use this article later on to refer our new potential customers to. Read more
  • A Post About Analyzing PHP

    01.09.2014
    PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. As of January 2013, PHP was installed on more than 240 million websites (39% of those sampled) and 2.1 million web servers. Originally created by Rasmus Lerdorf in 1994, the reference implementation of PHP (powered by the Zend Engine) is now produced by The PHP Group. While PHP originally stood for Personal Home Page, it now stands for PHP: Hypertext Preprocessor, which is a recursive acronym. Read more
  • Asterisk: PVS-Studio Takes Up Telephony

    26.08.2014
    Asterisk is a software implementation of a telephone private branch exchange (PBX); it was created in 1999 by Mark Spencer of Digium. Like any PBX, it allows attached telephones to make calls to one another, and to connect to other telephone services, such as the public switched telephone network (PSTN) and Voice over Internet Protocol (VoIP) services.

  • What's the Difference Between Static Analysis and Compiler Warnings?

    18.08.2014
    Visiting forums, you can often meet people who believe that compiler warnings are more than enough for controlling the basic types of errors in programs' code. I want to show you that it's a wrong belief. Read more
  • Checking GIMP's Source Code with PVS-Studio

    15.08.2014
    To check GIMP, we should first find a way to get it compile successfully. This task is far from easy, that's why we had been constantly delaying the check. However, the project is too famous, and we were very interested to find out its quality. So we have conquered our laziness and completed the analysis. Read more
