PVS-Studio is now in Compiler Explorer!

By Andrey Karpov | Jul 6, 2020 04:39 AM | Tags: static code analysis pvs-studio godbolt compiler explorer

Now you can quickly and easily analyze the code for errors right on the godbolt.org site (Compiler Explorer). This feature opens up a large number of new possibilities – from quenching curiosity about the analyzer's abilities to being able to quickly share check results with a friend. Caution – GIFs!

PVS-Studio is now in Compiler Explorer

by George Gribkov

From the article:

If you want to see the output of your program, you can open the execution window by clicking "Add new... - > Execution only" in the code editor (not in the compiler window). In the gif below, you can see the output of the lab work taken from our page about free usage of PVS-Studio by students and teachers.

SonarQube / SonarCloud Improved Analysis -- Alexandre Gigleux

With recent releases SonarQube and SonarCloud offer expanded compiler support and additional security-related rules.

Improved C/C++ analysis

By Alexandre Gigleux

From the article:

There are tons of C/C++ compilers out there and we always get many requests by many users about additional compilers support. We listened and added the support of 10+ compilers to allow more developers to benefit from our C/C++ rules.

We want to help C/C++ developers to deliver code in production without vulnerabilities and more precisely we want to avoid buffer overflow to be exploited by hackers. This is why we implemented 4 rules looking at APIs that could be badly used and that open the door to buffer overflow attacks

Polymorphic Allocators, std::vector Growth and Hacking

by Bartlomiej Filipek

From the article:

The concept of a polymorphic allocator from C++17 is an enhancement to standard allocators from the Standard Library.

It’s much easier to use than a regular allocator and allows containers to have the same type while having a different allocator, or even a possibility to change allocators at runtime.

Let’s see how we can use it and hack to see the growth of std::vector containers...

ModernCppStarter & PVS-Studio Static Code Analyzer

One of the ways to improve software quality is to check source code with static analysis tools. This section explains how to use the PVS-Studio analyzer to check projects built on ModernCppStarter. We provide a free license for open-source projects.

ModernCppStarter & PVS-Studio Static Code Analyzer

by PVS-Studio Team

From the article:

plog-converter will convert the report into the errorfile format (similar to GCC's messages), which can be conveniently viewed in a terminal window and the IDE. You can also have the report converted to an HTML file by using the -t fullhtml flag. Use the flags -a and -d to filter diagnostics. Run the plog-converter --help command to view the full list of available options.

C++ Template: A Quick UpToDate Look(C++11/14/17/20)

by Vishal Chovatiya

From the article:

I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.

I will start with a simple class/function template and as we move along, will increase the complexity. And also cover the advance topics like the variadic template, nested template, CRTP, template vs fold-expression, etc. But, yes! we would not take deeper dive otherwise this would become a book rather than an article.

Getting up to date.

The C++ Lambda Story Book

by Bartlomiej Filipek

From the article:

Lambda Expressions appeared in C++11, and since then they become one of the most distinguishing features of Modern C++. What’s more, with each revision of the Standard the ISO Committee improved the syntax and capabilities of lambdas, so they are even more comfortable to use.

Read on to see how you can learn all the details of this powerful modern C++ feature.
