The code analysis platform SonarQube announces the next step for C++.

SonarQube C++ analysis offers more efficient analysis and deeper Code Guildelines coverage

By Alex Gigleux

From the article:

We’re proud to announce the following improvements to the C++ analyzer:

  • faster analysis thanks to incremental mode
  • broader coverage of the C++ Core Guidelines
  • improved diagnostic reproduction for failed scans thanks to its automatic reproducer creation

C++ coroutines: The problem of the DispatcherQueue task that runs too soon, part 4--Raymond Chen

C++ coroutines: The problem of the DispatcherQueue task that runs too soon, part 4

by Raymond Chen

From the article:

Last time, we made another attempt to fix a race condition in C++/WinRT’s resume_foreground(Dispatcher­Queue) function when it tries to resume execution on a dispatcher queue. We did this by having the queued task wait until await_suspend was finished before allowing the coroutine to resume, and we found a nice place to put the synchronization object, namely in the awaiter, but even with that fix, we introduced additional memory barriers into the hot code path.

But it turns out all this work was unnecessary. We just had to look at the problem a different way.

The purpose of storing the result of Try­Enqueue into m_queued is so that await_resume can report whether the lambda was queued or not. But we can infer that information another way: The fact that our lambda is running means that got got queued. Because if the lambda were not queued, then it would never have run in the first place...

Take the Meeting C++ Community Survey!

Launching the Meeting C++ Community Survey

by Jens Weller

From the article:

One thing then often has bugged me when looking at the C++ community is that we don't really had good numbers on most things. Jetbrains, ISOCPP and Bartek's coding blog have launched surveys in the last years, which changed this a little. Also I've been doing some surveys on Twitter, giving some limited insight into C++ related topics. But Twitter surveys are very limited, and for a long time I had an idea on how to make this a continuous survey.

ACCU 2020 Registration is open -- ACCU

By Felix Petriconi | Jan 6, 2020 08:36 AM | Tags: community

The registration for the upcomming ACCU 2020 conference, 2020-03-25 to 2020-03-28, in Bristol, UK has opened.

ACCU 2020 Registration

by ACCU

About the conference:

Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.

Our keynote speaker are this year: Patricia Aas, Emily Bache, Kevlin Henney and Sean Parent

There are these preconference workshops the day before the conference:
