CLion 2021.1: New Code Analysis Options, Updates to Remote Mode, and Postfix Completion

by Anastasia Kazakova

About the release:

The CLion 2021.1 release is here! It catches more potential code quality issues,
enhances the debugging experience, and brings a more capable remote mode.

  • Code analysis
    • Global DFA is added and takes a whole translation unit of a program as a single unit for analysis to capture more potential issues.
    • New checks from MISRA C 2012 and MISRA C++ 2008 are introduced.
    • Clazy, a Qt-oriented static code analyzer, is now integrated into CLion.
  • Dynamic analysis tools
    • CLion can now calculate branch coverage.
    • Google Sanitizers, Valgrind Memcheck, and code coverage now works with remote toolchains.
  • Postfix completion for C and C++.
  • A new Open Project wizard.
  • Debugger:
    • GDB and LLDB have reached feature parity for core dump debugging in CLion.
    • Move execution point now works in the disassembly view.
  • For CMake projects:
    • Bundled CMake is upgraded to 3.19.
    • An ability to share CMake Profiles in VCS.
  • For Makefile projects:
    • Initial support for remote Makefile projects.
    • The Makefile Language plugin is now bundled into CLion.
  • VCS
    • Profile for pre-commit inspections.
    • Git commit templates.
  • Code With Me, a new JetBrains service for collaborative development and pair programming, is now bundled with CLion.

PVS-Studio Beta plugin for CLion (Win\Linux\macOS). It's less than a month away. Want to be the first to try it? Just sign up here.

PVS-Studio Early Access Program

by PVS-Studio Team

Description:

PVS-Studio is a static analyzer that detects errors and potential vulnerabilities in the source code of programs written in C, C++, C#, and Java. In 2021 we are planning to release the PVS-Studio plugin for C++ IDE – CLion.

Cling -- Beyond Just Interpreting C++

by Vassil Vassilev, Wim Lavrijsen, Alexandru Militaru

From the article:

In our previous blog post “Interactive C++ for Data Science” we described eval-style programming, interactive C++ in Notebooks and CUDA. This post will discuss some developed applications of Cling supporting interoperability and extensibility. We aim to demonstrate template instantiation on demand; embedding Cling as a service; and showcase an extension enabling on-the-fly automatic differentiation...

Example of How New Diagnostics Appear in PVS-Studio

By Andrey Karpov | Mar 20, 2021 10:11 AM | Tags: static code analysis pvs-studio open source misra covidsim bugs

Users sometimes ask how new diagnostics appear in the PVS-Studio static analyzer. We answer that we draw inspiration from a variety of sources: books, coding standards, our own mistakes, our users' emails, and others. Recently we came up with an interesting idea of a new diagnostic.

Example of How New Diagnostics Appear in PVS-Studio

by Andrey Karpov

From the article:

As for application software development, it doesn't make sense to enable them. The CovidSim project could do without them. Otherwise, a user will simply drown in a huge number of messages that are of little use in this case. For example, when experimenting with this set of diagnostics, we received more than a million warnings for some medium-sized open projects. Roughly speaking, every third line of code might be faulty in the view of MISRA. No one will scrape through all warnings, much less fix them. The project is either developed immediately taking into account MISRA recommendations, or this coding standard is irrelevant for it.

Creating other types of synchronization objects that can be used with co_await, part 2

From the article:

Last time, I teased a library for building awaitable synchronization objects. It builds on the code had earlier written for one-shot events by distilling the pattern to its essence and then rebuilding it in a more generic way...

PVS-Studio 7.12 New Features for Finding Safety and Security Threats

At the moment, PVS-Studio is developing not only as a static analyzer searching for code quality defects (quality control solution) but also as a solution for searching for security and safety defects.

PVS-Studio 7.12 New Features for Finding Safety and Security Threats

by Nikolay Mironov, Paul Eremeev

From the article:

Well, to waste no time, let's point out the additions right away. So, here is what's new, safe, and cool in PVS-Studio:

  • New diagnostic groups OWASP ASVS and The AUTOSAR C++14 Coding Guidelines have been added to the analyzer. Previously, the compliance of PVS-Studio diagnostic rules with these standards was available only on our website. Now we have more than 50 new diagnostic rules!
  • Now the analyzer shows information about the compliance of the warnings with the SEI CERT Coding Standard. This information formerly was available only on the PVS-Studio website.
  • The interface of our plugins for Visual Studio, JetBrains Rider, and IntelliJ IDEA has been improved to ease the work with analyzer messages that have safety and security standards identifiers.
  • New diagnostic groups (OWASP, AUTOSAR) in PlogConverter are supported.
  • New diagnostics (OWASP, AUTOSAR) are supported in SonarQube at the tag level. We classified our diagnostic rules by OWASP Top 10.

Registries: Bring your own libraries to vcpkg--Nicole Mazzuca

Registries: Bring your own libraries to vcpkg

by Nicole Mazzuca

From the article:

Are you working on a C++ project with library dependencies? Are you tired of maintaining a custom-built package management workflow with duct tape and git submodules? Then you should consider trying out a package manager. Perhaps you have been side-eyeing vcpkg for a while, and it looks like the perfect solution for your team, but for one problem: not all your dependencies are open source! Your company has internal libraries that they expect everyone to use too...
