Almost four years have passed since the PVS-Studio team checked the OpenToonz source code. This project is a very powerful tool for creating two-dimensional animation. Since the last check, with its help, such animated works as Mary and the Witch Flower, Batman-Ninja, Promare and others were created. As large studios continue using Toonz, why not check the quality of the source code again?

In August 2019, CMake introduced the long-awaited support for precompiled headers. Before that, one had to use different plugins, for example, Cotire. Right after the release of CMake with new functionality, there were several more improvements. But in the fall, we decided that we could already start using this feature, and rewrote our scripts. Later, we found a bug that generated incorrect parameters of the Clang compiler and prevented the launch of the PVS-Studio analyzer. The bug had to be fixed by ourselves.

A new post "How Can Developers Help Fight Coronavirus?" appeared in the Fluent{C++} blog. We have a practical consideration on this subject, although it is not directly related to COVID-19. If programmers would like to do something useful in this regard, we recommend fostering the efforts in the general development of research libraries in the field of medicine, and related applications. At least, even if developers can't add new capabilities, they can work on the quality of these projects.

The PVS-Studio analyzer can detect incorrect variants of the "double-checked locking" pattern implementation in C# programs. Sometimes users are not aware of the danger in the code indicated by the analyzer and the ways how to correct it. Therefore, we will illustrate with a practical example what the error detected by the V3054 warning can look like and how to fix the code.

This post continues the series of articles, which can well be called "horrors for developers". This time it will also touch upon a typical pattern of typos related to the usage of numbers 0, 1, 2. The language you're writing in doesn't really matter: it can be C, C++, C#, or Java. If you're using constants 0, 1, 2 or variables' names contain these numbers, most likely, Freddy will come to visit you at night. Go on, read and don't say we didn't warn you.

We continue making the use of PVS-Studio more convenient. Our analyzer is now available in Chocolatey, the package manager for Windows. We believe this will make it easier to deploy PVS-Studio, particularly in cloud services. So right off the bat, we also checked the source code of the same Chocolatey. Azure DevOps took on the role of the CI system.
