PVS-Studio is a tool for detecting bugs and security weaknesses in the source code of programs, written in C, C, C# and Java. It works in Windows, Linux, and macOS environment. PVS-Studio performs and generates a report that helps a programmer find and fix bugs.

Clang Static Analyzer. The Clang Static Analyzer is a source code analysis tool that finds bugs in C, C++, and Objective-C programs. Currently it can be run either as a standalone tool or within Xcode.The standalone tool is invoked from the command line, and is intended to be run in.

PVS-Studio performs a wide range of code checks, it is also useful to search for misprints and Copy-Paste errors. Examples of such errors:,.

The main value of static analysis is in its regular use, so that errors are identified and fixed at the earliest stages. There is no point in wasting looking for a bug that could be found with static analysis. So, let's point out that again - the main idea of static analysis is not to find one hidden bug on the day before the release, but to fix dozens of bugs day by day. The analyzer can be run at night on the server and warn about suspicious code fragments. Ideally, these errors can be detected and fixed before getting into the repository. PVS-Studio can automatically be launched immediately after the compiler for the files that have been just modified.

It works in Windows, Linux, and macOS. Quick start in Windows, Linux, and macOS PVS-Studio can integrate into Visual Studio development environment 2010-2017. If you use this IDE, then most likely you will just have to go to the menu of PVS-Studio plugin and choose 'Check Current Project'. Often, it can be a more complicated process, and you will need to integrate PVS-Studio into a build system, even an exotic one. The topic of integration is too broad to describe it here. You can find all the information in the detailed. One more point to notice - PVS-Studio for Windows and Linux has special utilities, gathering information about the compiler launches.

These tools allow doing a quick analysis of a project that gets compiled in any possible way. You can quickly try out the analyzer abilities, without wasting time on its integration with makefile or a build script. See the description of the utility (Windows) and (Linux/macOS). The technology of analysis. The pattern-based analysis on the basis of an abstract syntax tree is used to look for fragments in the source code that are similar to the known code patterns with an error. The type inference based on the semantic model of the program allows the analyzer to have full information about all variables and statements in the code.

The symbolic execution allows evaluating values of variables that can lead to errors, perform range checking of values. The data-flow analysis is used to evaluate limitations that are imposed on values of variables when processing various language constructs.

For example, values that a variable can take inside if/else blocks. Method annotations provide more information about the used methods than can be obtained by analyzing only their signatures. Simple and seamless integration with Visual Studio 2010-2017.

Automatic analysis of individual files after their recompilation. Online reference guide concerning all the diagnostics available in the program, on the web site and documentation (presented as a.pdf file) Up to 550 pages of documentation. Saving and loading analysis results allow doing overnight checks - during the night the analyzer does the scanning and provides you with the results in the morning. You can save analysis results as HTML with full source code navigation.

Project analysis run from the command line: helps integrate PVS-Studio into overnight builds; a new log will be issued in the morning. Great scalability Support of multi-core and multi-processor systems with the possibility to specify the number of the cores to use; IncrediBuild support. Interactive filtering of the analysis results (the log file) in the PVS-Studio window: by the diagnostic number, file name, the keyword in the text of the diagnostic.

Automatic check of PVS-Studio updates (during the work in IDE and overnight builds). BlameNotifier utility. The tool allows you to send e-mail notifications to the developers about bugs that PVS-Studio found during a night run. A large number of options for integration into projects developed under Linux and macOS. Mark as False Alarm - ability to mark the code to suppress a certain diagnostic in a particular code fragment. Mass Suppression - ability to suppress all old messages raised for the legacy code, so that the analyzer reports 0 warnings. You can always go back to the suppressed messages later.

This feature allows you to seamlessly integrate PVS-Studio into your development process and focus on errors found in new code only. Error statistics can be viewed in Excel. Ability to view the speed of error correction, amount of bugs found for a certain period of time and so on. Relative paths in report files to view them on different machines.

CLMonitoring feature allows analyzing the projects that have no Visual Studio files (.sln/.vcxproj); in case the CLMonitoring functionality is not enough, there is a possibility to integrate PVS-Studio in a Makefile-based build system manually. pvs-studio-analyzer - a utility similar to CLMonitoring, but working under Linux and macOS. Possibility to exclude files from the analysis by name, folder or mask; to run the analysis on the files modified during the last N days. Integration with SonarQube. It is an open source platform, designed for continuous analysis and measurement of code quality. Supported languages and compilers. Windows.

Viewing static analyzer results in a web browser What is Static Analysis? The term 'static analysis' is conflated, but here we use it to mean a collection of algorithms and techniques used to analyze source code in order to automatically find bugs.

The idea is similar in spirit to compiler warnings (which can be useful for finding coding errors) but to take that idea a step further and find bugs that are traditionally found using run-time debugging techniques such as testing. Static analysis bug-finding tools have evolved over the last several decades from basic syntactic checkers to those that find deep bugs by reasoning about the semantics of code.

The goal of the Clang Static Analyzer is to provide a industrial-quality static analysis framework for analyzing C, C, and Objective-C programs that is freely available, extensible, and has a high quality of implementation. Part of Clang and LLVM As its name implies, the Clang Static Analyzer is built on top of. Strictly speaking, the analyzer is part of Clang, as Clang consists of a set of reusable C libraries for building powerful source-level tools. The static analysis engine used by the Clang Static Analyzer is a Clang library, and has the capability to be reused in different contexts and by different clients. Important Points to Consider While we believe that the static analyzer is already very useful for finding bugs, we ask you to bear in mind a few points when using it.

Work-in-Progress The analyzer is a continuous work-in-progress. There are many planned enhancements to improve both the precision and scope of its analysis algorithms as well as the kinds of bugs it will find. While there are fundamental limitations to what static analysis can do, we have a long way to go before hitting that wall. Slower than Compilation Operationally, using static analysis to automatically find deep program bugs is about trading CPU time for the hardening of code.

Because of the deep analysis performed by state-of-the-art static analysis tools, static analysis can be much slower than compilation. While the Clang Static Analyzer is being designed to be as fast and light-weight as possible, please do not expect it to be as fast as compiling a program (even with optimizations enabled). Some of the algorithms needed to find bugs require in the worst case exponential time. The Clang Static Analyzer runs in a reasonable amount of time by both bounding the amount of checking work it will do as well as using clever algorithms to reduce the amount of work it must do to find bugs. False Positives Static analysis is not perfect. It can falsely flag bugs in a program where the code behaves correctly. Because some code checks require more analysis precision than others, the frequency of false positives can vary widely between different checks.

Our long-term goal is to have the analyzer have a low false positive rate for most code on all checks. Please help us in this endeavor. False positives cannot be addressed unless we know about them.

More Checks Static analysis is not magic; a static analyzer can only find bugs that it has been specifically engineered to find. If there are specific kinds of bugs you would like the Clang Static Analyzer to find, please feel free to file or contribute your own patches.
