I often hear in various interpretations the phrase: "The given examples show not the code incorrect from the viewpoint of porting to x64 systems, but the code incorrect in itself". I would like to discuss and theorize a bit on this point in the blog. Please, take this note with a bit of humor.
I have found a nice code fragment with an error in one project. The PVS-Studio analyzer noticed it. But I didn't believe it at first: I thought the analyzer had been mistaken and considered launching the debugger. Then I looked closer. Oh yes, an error indeed!

Many C++ programmers (especially beginners) either underestimate or don't actually know the power of modern C++ compilers. In the presentation I discuss architecture of modern compilers, how big they are and features (including recently emerged ones) that everyone should be aware of. I also cover tooling and ecosystem that has grown around compilers.
In this article, you're going to find 60 terrible coding tips — and explanations of why they are terrible. It's a fun and serious piece at the same time. No matter how terrible these tips look, they aren't fiction, they are real: we saw them all in the real programming world.
If the coding bug is banal, it doesn't meant it's not crucialPVS-Studio
Spreading the word about PVS-Studio static analyzer, we usually write articles for programmers. However, some things are seen by programmers quite one-sided. That is why there are project managers who can help manage the process of the project development and guide it to the right direction. I decided to write a series of articles, whose target audience is project managers. These articles will help better understand the use of static code analysis methodology. Today we are going to consider a false postulate: "coding errors are insignificant".

Monitoring a program that monitors computer networksPVS-Studio
There exists the NetXMS project, which is a software product designed to monitor computer systems and networks. It can be used to monitor the whole IT-infrastructure, from SNMP-compatible devices to server software. And I am naturally going to monitor the code of this project with the PVS-Studio analyzer.
Searching for bugs in Mono: there are hundreds of them!PVS-Studio
It's very interesting to check large projects. As a rule, we do manage to find unusual and peculiar errors, and tell people about them. Also, it's a great way to test our analyzer and improve all its different aspects. I've long been waiting to check 'Mono'; and finally, I got the opportunity. I should say that this check really proved its worth as I was able to find a lot of entertaining things. This article is about the bugs we found, and several nuances which arose during the check.
Espressif IoT Development Framework: 71 Shots in the FootAndrey Karpov
One of our readers recommended paying heed to the Espressif IoT Development Framework. He found an error in the project code and asked if the PVS-Studio static analyzer could find it. The analyzer can't detect this specific error so far, but it managed to spot many others. Based on this story and the errors found, we decided to write a classic article about checking an open source project. Enjoy exploring what IoT devices can do to shoot you in the foot.
A Bonus to the "Three Interviews About Static Analyzers" Article, or Intervie...Andrey Karpov
About a week ago, I published the "Three Interviews About Static Code Analyzers" article at Habrahabr.
This article presents opinions of three experienced programmers from the companies Acronis,
AlternativaPlatform and Echelon Company concerning software development methodologies as well as
some of their ideas about using static code analyzers.
Since the article was sponsored by the OOO "Program Verification Systems" company, developer of the
PVS-Studio static analyzer, I asked Andrey Karpov (CTO) to answer some questions too. In particular, I
asked him to comment upon the most interesting aspects and ideas of all the three interviews and say a
few words for colleagues and readers, too. Here's what we've got - one more interesting interview.
Analysis of PascalABC.NET using SonarQube plugins: SonarC# and PVS-StudioPVS-Studio
In November 2016, we posted an article about the development and use of the PVS-Studio plugin for SonarQube. We received great feedback from our customers and interested users who requested testing the plugin on a real project. As the interest in this subject is not decreasing, we decided to test the plugin on a C# project PascalABC.NET. Also, it should be borne in mind, that SonarQube have their own static analyzer of C# code - SonarC#. To make the report more complete, we decided to test SonarC# as well. The objective of this work was not the comparison of the analyzers, but the demonstration of the main peculiarities of their interaction with the SonarQube service. Plain comparison of the analyzers would not be fair due to the fact that PVS-Studio is a specialized tool for bug detection and potential vulnerabilities, while SonarQube is a service for the assessment of the code quality by a large number of parameters: code duplication, compliance with the code standards, unit tests coverage, potential bugs in the code, density of comments in the code, technical debt and so on.
In February 2014, the Argentinian studio OKAM made public the source code of their multi-platform game engine Godot Engine and not so long ago, version 1.0 was released. As you have already guessed, in this article we will talk about the analysis of this project's source code and its results. Analysis was done with the PVS-Studio static code analyzer. Besides the introductory purpose, this article also pursues some practical aims: the readers can learn something new while the project developers can fix errors and bottlenecks. But first things first.
Regular use of static code analysis in team developmentPVS-Studio
Static code analysis technologies are used in companies with mature software development processes. However, there might be different levels of using and introducing code analysis tools into a development process: from manual launch of an analyzer "from time to time" or when searching for hard-to-find errors to everyday automatic launch or launch of a tool when adding new source code into the version control system.
Undefined behavior is closer than you thinkAndrey Karpov
Some people think that undefined behavior is caused only by gross errors (accessing outside the bounds of the array, for instance) or inadequate constructions (i = i++ + ++i, for example). That's why it is quite surprising when a programmer sees undefined behavior in the code that used to work correctly, without arousing any suspicion. One should never let his guard down, programming in C/C++. Because hell is closer than you may think.

A Collection of Examples of 64-bit Errors in Real ProgramsAndrey Karpov
This article is the most complete collection of examples of 64-bit errors in the C and C++ languages. The article is intended for Windows-application developers who use Visual C++, however, it will be useful for other programmers as well.
Static code analysis for verification of the 64-bit applicationsPVS-Studio
The coming of 64-bit processors to the PC market causes a problem which the developers have to solve: the old 32-bit applications should be ported to the new platform. After such code migration an application may behave incorrectly. The article is elucidating question of development and appliance of static code analyzer for checking out of the correctness of such application. Some problems emerging in applications after recompiling in 64-bit systems are considered in this article as well as the rules according to which the code check up is performed.

My name is Andrey Karpov. I develop software for developers, and I'm fond of writing articles on code quality issues. In this connection, I have met the wonderful man Walter Bright who has created the D language. In the form of an interview, I will try to learn from him how the D language helps programmers get rid of errors we all make when writing code.
Our team wrote three articles related to the code analysis of Tizen operating system. The operating system contains a lot of code, so this is the reason why it is a fertile ground for writing different articles. I think that we will go back again to Tizen in future, but right now other interesting projects are waiting for us. So, I will sum up some results of the work done and answer a number of questions that have arisen after the previously published articles.
The Ultimate Question of Programming, Refactoring, and EverythingAndrey Karpov
Yes, you've guessed correctly - the answer is "42". In this article you will find 42 recommendations about coding in C++ that can help a programmer avoid a lot of errors, save time and effort. The author is Andrey Karpov - technical director of "Program Verification Systems", a team of developers, working on PVS-Studio static code analyzer. Having checked a large number of open source projects, we have seen a large variety of ways to shoot yourself in the foot; there is definitely much to share with the readers. Every recommendation is given with a practical example, which proves the currentness of this question. These tips are intended for C/C++ programmers, but usually they are universal, and may be of interest for developers using other languages.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Are 64-bit errors real?
1. Are 64-bit errors real?
Author: Andrey Karpov
Date: 08.11.2009
I often hear in various interpretations the phrase: "The given examples show not the code incorrect
from the viewpoint of porting to x64 systems, but the code incorrect in itself". I would like to discuss and
theorize a bit on this point in the blog. Please, take this note with a bit of humor.
First, let's begin with saying that any code written in C++ is incorrect by itself. Only that code will be
correct which consists of the empty function main, yet I'm not sure about it. It is impossible to write an
ideal correct program in C/C++. For you should consider that the program should work on a 12-, 16-, 32-,
64-, ...-bit system. The program, if possible, shouldn't allocate memory dynamically because somewhere
it is missing. Also, it shouldn't use functions like scanf for you may need to place the program into a
controller where there is no input device. The program mustn't use type conversions. Any type
conversion is a potential error on some platform. And perhaps it is better to write the program with the
help of trigraphs - you never know... :)
Well, I mean that there are no ideally correct programs in C/C++. You can seek to create such a program
but you will never create it. In reality, when writing programs an admissible level of correctness and
supposition about the execution environment is chosen and the program is written within the
framework of this model.
So, any code is incorrect by itself from the viewpoint of an ideal programmer with golden hands living in
vacuum. But we can suppose that a particular code be correct in some particular conditions. When the
conditions (the environment) change the code may become incorrect. In what way it becomes incorrect
depends on the external changes. Search of errors occurring when the execution environment changes
can be arranged in a group and successfully diagnosed, while the approach "everything in the program is
incorrect" is irrational.
Let's consider an example. We have a program to port into a controller which won't have a console. The
program has some number of cout, cin, printf, scanf. We should find and "deactivate" these functions.
Suppose that input be performed through the ports connected to some handle on the device's case.
There is no sense in saying that the code is bad, the programmer who wrote it is bad only because he
hadn't foreseen that there can be no console and one cannot disable all these sections by one pressure.
It won't help us. And there is no sense in trying to perform an ideal refactoring to create an ideal
program. We should only find and fix the necessary fragments. One can invent a static analyzer of
"input-output issues in controllers"-diagnosis kind. And it will be helpful! But, honestly, all this is due to
imperfect code of course :-)
The example above is exaggerated but I just want to show that when one is writing code one cannot
foresee everything. One doesn't know that in five years this code will be placed into a controller, ported
on a 64-bit system or adapted to a submarine. It is rather difficult to foresee some things.
Programmers have and maintain that code which they have. It can contain a lot of magic numbers,
THOUSANDS of expressions where signed and unsigned types are used together, where many warnings
may be disabled because one has to use LARGE old third-party libraries. And no one will bother to
2. perform total refactoring of such projects to make them more beautiful, portable etc. And if one insists
on this - this person should be fired. :) In reality, you should solve real tasks. You should add new
functionality, organize maintenance on existing systems. If necessary, you should port the code on 64-
bits. But when you port the code on a 64-bit system, it is this task that will be solved and not the task of
how to make the code maximum portable. And here we face the practical task of detecting particular
magic numbers (but not all of them), unsafe expressions with signed and unsigned types (but not all of
them).
My position may seem wrong to many people as if I'm urging to write bad code and then use various
crutches (which I sell myself) to fix it in some places. I am simply a practitioner. And also I call many
things by their names. :)
Mostly, program code is BAD. And it works more or less well because it is lucky. Unfortunately,
programmers are persistent in not admitting it. Any "code-shaking" (changing of the compiler, execution
environment etc) reveals a layer of particular types of errors. I understand that there are no "64-bit"
errors. There are just errors in code. They are always present in code. But some errors will occur on a
64-bit system. I tell developers about these errors and hope it will help them. And it is these errors that I
call "64-bit errors".
