Codebase. The PVS-Studio plugin provides a set of rules that correspond to the analyzer warnings. We can add all of them to the quality profile or disable any rules if necessary. According to the configured quality profile, SonarQube will display or not display warnings after analyzing our code. Now, we need to configure the Quality Profile. To do so go to the Quality Profiles tab and click Create as shown in the picture below. In the appeared window enter a profile name (it can be random). In our case, the name is PVS-Studio Way. Then, select the language. C++ is relevant for us now. After that, click Create. Then go to the Rules tab, select the Repository category, and select PVS-Studio C++. Next, click Bulk Change and Activate In, in the appeared window select our created profile, that is, PVS-Studio Way. SonarQube is set up and ready to go. Analysis Then, we'll configure the project analysis directly using the PVS-Studio analyzer. Download the source code with the following command: git clone generate the project files: make.bat full nobuild generate the necessary additional files, compile the build_windows_Full_x64_vc15_Release\INSTALL.vcxproj project for that. Run the analysis with the following command "c:\\Program Files (x86)\\PVS-Studio\\PVS-Studio_Cmd.exe" \ -t build_windows_Full_x64_vc15_Release\\Blender.sln \ -o blender.plog --sonarqubedata -r So, we have the files blender.plog and sonar-project.properties, and we can push the results of our analysis to SonarQube. Use the sonar-scanner utility to do this. Sonar scanner You can download the utility here. Download the archive by the link, unzip it. For example, in our case, it is placed in the directory D:\sonar\sonar-scanner-4.5.0.2216-windows. Edit the D:\sonar\sonar-scanner-4.5.0.2216-windows\conf\sonar-scanner.properties file by adding the following line to it: sonar.host.url= Where sonarServer is the name of the machine where SonarQube is installed. Run the following command: D:\sonar\sonar-scanner-4.5.0.2216-windows\sonar-scanner.bat \-Dsonar.projectKey=blender -Dsonar.projectName=blender \-Dsonar.projectVersion=1.0 \-Dsonar.pvs-studio.reportPath=blender.plog Note that the command is called

Errors end up being fixed at other levels of quality control (for example, using tests) instead of being found and fixed immediately after they hit the code. Therefore, we decided to try a new work format with open source projects. That is a regular, daily code review of one (for a start) project. In this case, the check will be set up in a way that we'd have to view analyzer warnings covering only changed code or newly written code. It's faster than viewing the full analyzer report, and most importantly, it will allow discovering a potential error very quickly. When we find something really exciting, we'll make short notes or even write a post on Twitter. We hope that this format will allow us to better promote more correct practices of static analysis regular use and will bring additional benefits to the open-source community. We decided to choose the Blender project as the first project to analyze. You can tell us what additional projects you'd like us to analyze. Also, we'll describe the errors found in them. Regular analysis configuration For our task, we consider the joint effort of PVS-Studio – SonarQube tools to be the best solution for regular analysis. Further, we'll talk about the configuration of the selected tools: how to run and configure SonarQube; we'll describe how to analyze the project and how to upload the results to be displayed. Why we chose SonarQube PVS-Studio can do a lot: analyze, send out notifications about warnings, and filter them. Moreover, it can also integrate into different systems to display warnings. Not only to get the check results but also to additionally test more PVS-Studio operating modes, we decided to try to configure the display of results for our task in SonarQube.

The short versionThe long versionThe PVS-Studio C# updateIssues and solutionsSome thoughts Every year, Microsoft releases a new version of .NET. This is a major event that prompts us to update PVS-Studio to support new features. Today, we'll talk about the PVS-Studio team's pain when updating Roslyn, an integral part of .NET. For your convenience, I've divided the article in two parts: a short one for those who want to quickly find reasons for the changes made in PVS-Studio 7.34, and a long one for those who want to know the whole story. The short version The PVS-Studio 7.34 release brings support for .NET 9 and all new C# language features. To make it possible, we had to update Roslyn, which PVS-Studio uses for syntax analysis of the C# language, as well as to update the interdependent MSBuild libraries used for model building and parsing of C# and C++ projects (.csproj, .vcxproj). Starting with PVS-Studio 7.34, the analysis of C# .NET, .NET Standard, and .NET Framework projects also requires the .NET 9 SDK to be installed on the system running the SDK-style analysis. Classic .NET Framework projects remain unchanged if the system running the analysis has MSBuild or Visual Studio versions 2017 and later installed. If you only have MSBuild or Visual Studio versions 2015 and earlier installed on your system, you also need the .NET 9 SDK to analyze classic .NET Framework projects. This change was prompted by the loss of backward compatibility in the Roslyn libraries used to analyze

This application here. Now let's proceed to the deployment. SonarQube stores all the data in the database. You can use different databases, but the recommended one is PostgreSQL. Let's set it up first. Configuring PostgreSQL Download the latest version here. Install it and create a database for SonarQube. To do this, first, create a user named sonar. Run the following command in the psql command line: CREATE USER sonar WITH PASSWORD '12345'; You can also use pgAdmin for this and other operations. Now we need to create the database named sonarqube using the CREATE DATABASE command. It looks like this in our case: CREATE DATABASE sonarqube OWNER sonar; The database is ready, let's start configuring SonarQube. SonarQube configuration Download and install SonarQube. You can get the latest version here. The distribution itself is an archive. We need to unpack the archive to the C directory:\sonarqube\sonarqube-8.5.1.38104. Then, edit the file C:\sonarqube\sonarqube-8.5.1.38104\conf\sonar.properties. We'll add there the following info on our created database: sonar.jdbc.username=sonarsonar.jdbc.password=12345sonar.jdbc.url=jdbc:postgresql://localhost/sonarqube SonarQube will see the database that we created and will start working with it. Next, you'll need to install the plugin for PVS-Studio. The plugin is in the directory where PVS-Studio is installed. It is C:\Program Files (x86)\PVS-Studio by default. We need a sonar-pvs-studio-plugin.jar file. Copy it to the directory with SonarQube C:\sonarqube\sonarqube-8.5.1.38104\extensions\plugins. You also need to download the sonar-cxx-plugin, click here to do it. At the time of writing, this is sonar-cxx-plugin-1.3.2.1853.jar. We need to copy this plugin to the C:\sonarqube\sonarqube-8.5.1.38104\extensions\plugins directory. Now you can run SonarQube. To do this, run C:\sonarqube\sonarqube-8.5.1.38104\bin\windows-x86-64\StartSonar.bat. Let's start setting up via the web interface. Go to the browser at sonarServer:9000. Here sonarServer is the name of the machine where SonarQube is installed. Quality Profile configuration The quality profile is a key component of SonarQube, which defines a set of rules for the

Projects from Visual Studio\MSBuild versions 2015 and earlier. Roslyn now uses its own .NET SDK-based server component for this, which requires the .NET SDK to be installed on the system. The short version is over. The long version The PVS-Studio C# update PVS-Studio 7.34 introduced support for .NET 9 and all new C# language features. By the way, I invite you to read our articles about the changes:What's new in .NET 9?C# 13 update overview To support .NET 9, we had to update the Roslyn and MSBuild libraries. PVS-Studio and Roslyn use MSBuild to build a project model (the design-time build). This is a fairly complex process that requires some knowledge from either an employee or their mentor. One might think, "What's so hard about just clicking update on the right NuGet packages in the IDE?" Before we supported Visual Studio 2017, this was true. I could start telling you what's changed and why it's not enough to update the packages, but I'd rather share a link to an article that covers this topic. Although, I still have to give you a brief introduction. What does one have to do to support the new .NET and why? Starting with the 15 (VS 2017) release, MSBuild can't find its own installation directory. I think this is related to MSBuild 15 and newer not being written to the registry. The following solution has been proposed to work around this issue:We would create our custom toolset. To do this, we needed to include

To collect necessary information on the project compilation while the project is being built. Execute the following command to build the project and track the progress of its compilation: pvs-studio-analyzer trace [-o ] -- build_command The build_command command is used for building the project, for example: pvs-studio-analyzer trace -- cmake build . By default, the strace_out file is created as a result of tracing. You can learn more about the tracing mode here. How to start project analysis After receiving the compilation trace file (strace_out) or the JSON Compilation Database (compile_commands.json), you can run the analysis by executing the following command: pvs-studio-analyzer analyze -o /path/to/PVS-Studio.log \ -e /path/to/exclude-path \ -j The analyze command requires strace_out or compile_commands.json files in the current working directory. You can explicitly specify the location of these files using the ‑‑file (-f) flag. How to handle analysis results To convert the analyzer report to various formats (*.xml, *.tasks, etc.), use plog-converter. You can read more about this utility here. Here is an example of how to convert the analyzer report to the json format: plog-converter -a GA:1,2 \ -t json \ -o /path/to/Analysis_Report.json \ /path/to/PVS-Studio.log The analyzer warnings are saved in the specified Analysis_Report.json file.

Every year, Microsoft releases a new version of .NET, and .NET 9 is already delivered! Like the last time, we dive into hunting errors in .NET source code. Let's see what we uncover this time! Our team, like many C# developers, keeps an eye on .NET releases and new features, so we've put together some content on this topic! I suggest checking out what's been added in .NET 9 and C# 13:What's new in .NET 9?What's new in C# 13: overview These articles explore the key features introduced in the latest versions of .NET and C#. However, we don't just monitor .NET releases for new features—we focus on supporting the latest .NET versions in the PVS-Studio static analyzer. When we implemented support for .NET 9, we faced some interesting challenges. So, we wrote an article about them: How to update library and get swamped with this task. Roslyn and PVS-Studio 7.34 update. Now .NET 9 is fully supported, and you can start using the analyzer in your projects right away. Let's move on to analyzing the .NET 9 source code; we'll explore the release code available on GitHub. Last year, I told you that I had to switch from Visual Studio 2022 to VS Code to analyze .NET 8 because VS 2022 couldn't handle the massive .sln of .NET 8—it either restarted or crashed repeatedly. I was lucky that the PVS-Studio plugin for VS Code was released just in time. This year, I immediately decided to analyze it via VS Code, but for the sake of interest I also gave VS 2022 a shot. And guess what? No restarts or crashes, but code navigation remained challenging enough. Continuous performance enhancements made a noticeable impact—let's see how it will be next year :) Now let's explore the detected errors. Fragment 1 struct StackValue{ .... public override bool Equals(object obj) { if (Object.ReferenceEquals(this, obj)) return true; if (!(obj is StackValue)) return false; var value = (StackValue)obj; return this.Kind == value.Kind && this.Flags == value.Flags && this.Type == value.Type; }} Do you think there are no problems? Oh no, there definitely are. V3161 Comparing value type variables with 'ReferenceEquals' is incorrect because 'this' will be boxed. ILImporter.StackValue.cs 164 In this scenario, a value type object is compared by reference. The ReferenceEquals method accepts parameters of the Object type. When a value type is passed, it gets boxed. The reference created on the heap
