How to speed up building ang analyzing of your project with IncrediBuild?

By Andrey Karpov | May 17, 2021 06:40 AM | Tags: pvs-studio incredibuild devops

"How much longer are you going to build it?" - a phrase that every developer has uttered at least once in the middle of the night. Yes, a build can be long and there is no escaping it. One does not simply redistribute the whole thing among 100+ cores, instead of some pathetic 8-12 ones. Or is it possible?

How to speed up building ang analyzing of your project with IncrediBuild?

by Maxim Zvyagintsev

From the article:

At the same time, the build completed successfully, but something really bad happened now. I had to dig into the logs, or rather, the compilation dump. That's where I found the problem. The point was that these macros are declared in the local precompiled header, whereas we only want to preprocess the file. However, the include header that was used to generate the precompiled header is different from the one that is included to the source file! The file that is used to generate the precompiled header is a 'wrapper' around the original header included into the source, and this wrapper contains all of the required macros.

Somehow, it so happens that we write about our diagnostics, but barely touch upon the subject of how we enhance the analyzer's internal mechanics. So, for a change, today we'll talk about a new useful upgrade for our data flow analysis.

PVS-Studio Learns What strlen is All About

by Andrey Karpov

From the article:

Can you see it? To be honest, we did not notice it immediately and our first thought was, "Oh no, we broke something!" Then we saw what was up and took a minute to appreciate the advantages of static analysis. PVS-Studio warned: V512 A call of the 'strcpy' function will lead to overflow of the buffer 'astr'. asm.cpp 21 Still don't see the error? Let's go through the code step by step.

Finding Bugs with AddressSanitizer: MSVC Compiler

by Augustin Popa

From the article:

The AddressSanitizer (ASan) is generally available for MSVC since the recently-released Visual Studio 2019 version 16.9. We’ve already shown how easy it can be to find bugs in even production-ready code like EASTL. Here I’ll share an example of how it found a real bug in the MSVC compiler itself.

The idea was straightforward: ASan finds bugs, and we’re always interested in finding bugs in the compiler. Just like you can turn ASan on in your projects and run your tests, we’ve been turning on ASan on our project (the compiler) and running it on our tests. Sure enough, this found bugs...
