Here is my report from the July 2022 ISO C++ committee virtual meeting.
Meeting Report
by Timur Doumler
About the report:
This was the last virtual plenary before WG21 returns to meeting in person, and the last plenary where we voted new features into C++23, which is now in feature freeze.

Utah C++ Programmers has released a new video:
Adding a REST API with Pistache
by Richard Thomson
From the video description:
Many times you need to integrate your C++ infrastructure with services written in other languages on other machines from other teams. In the past, this might have been accomplished with custom RPC (remote procedure call) networking services that exposed resource data in your application to authorized clients.
HTTP REST (representational state transfer) APIs have become a common architectural pattern for exposing resource data across the network. With SSL/TLS (secure socket layer/transport layer security) connections and the HTTPS protocol, the client/server exchange can be secured. Authentication can be implemented with a session mechanism or the built-in authentication mechanisms in HTTP itself.
This month, Richard Thomson will give us an introduction to pistache, a high-performance REST toolkit written in C++. After an overview of the library, we'll look at what it takes to implement an HTTP server that responds to resource requests.

Why you should use std::move only rarely
by Andreas Fertig
From the article:
In today's post, I try to tackle a topic that comes up frequently in my classes, move semantics, and when to use std::move. I will explain to you why not say std::move yourself (in most cases).

Registration is now open for CppCon 2022, which starts on September 11 and will again be held both in person and online. To whet your appetite for this year’s conference, we’re posting videos of some of the top-rated talks from last year’s conference. Here’s another CppCon talk video we hope you will enjoy – and why not register today for CppCon 2022 to attend in person, online, or both!
Lessons Learned from Packaging 10,000+ C++ Projects
by Bret Brown & Daniel Ruoso
Summary of the video:
At Bloomberg, we maintain a system that coherently builds and integrates more than 10,000 C++ packages that are maintained independently by thousands of software engineers on hundreds of teams across our Engineering department. In this talk, we will go over the lessons we have learned about maintaining these packages, as well as how package management should interact with third-party libraries, third-party tools, build systems, IDEs, static analysis tools, and refactoring automation. We hope this will start a conversation around the potential requirements for a more complete package management solution in the C++ ecosystem.

Improved automated instance construction in C++
by Marius Elvert
From the article:
In my last blog post, I wrote about how I am automatically deducing constructor parameters in my dependency injection container. The approach had a major drawback: It worked only for 2 or more parameters, since there was an ambiguity with copy- or move-constructors with exactly one parameter...

The STE||AR Group has released V1.8.1 of HPX -- A C++ Standard library for Concurrency and Parallelism.
HPX V1.8.1 Released
We have released HPX 1.8.1 that adds a number of small new features and fixes a handful of problems discovered since the last 1.8.0 release, in particular: a lot of work has been done to improve vectorization support for our parallel algorithms. HPX now supports using EVE – the Expressive Vector Engine as a vectorization backend. More work was done towards full compatibility with the sender/receiver proposal P2300. We have fixed all collective operations to properly avoid overlapping consecutive operations on the same communicator. We also fixed a dangling reference problem while serializing non-default constructible types. We have added support for static linking on Windows (using MSVC) and have added support for M1/MacOS based architectures. A full list of changes can be found in the release notes.
If you have any questions, comments, or exploits to report you can reach us on IRC or Matrix (#ste||ar on libera.chat) or email us at hpx-users. We depend on your input!
You can download the release from our releases page or check out the 1.8.1 tag using git. A full list of changes can be found in the release notes.
HPX is a general-purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++20 Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 and C++20 parallel algorithms, including a full set of parallel range-based algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the features related parallelism and concurrency as specified by the upcoming C++23 Standard, the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g., compute clusters) and for heterogeneous systems (e.g., GPUs).
HPX seamlessly enables a new Asynchronous C++ Standard Programming Model that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parallelism and concurrency.

Exceptional C++
by Victor Ciura
Summary of the video:
When writing code we usually focus our attention on the happy paths - that’s where the interesting stuff happens. But there are also plenty of exciting things happening on the error handling flow, too. Although not universally loved/used, exceptions are a powerful mechanism of maneuvering execution on the unhappy path.
Even if std::exception and related machinery are not your cup of tea, you might care about hardware faults or OS signals like access violations, page errors, ALU overflows.
Let’s take a deep dive and explore what happens when an exception occurs, both at the application level and the OS level. We’ll explore the unwind process, the compiler generated code, the CRT hooks available and other exception internals. As we’re taking the scenic Windows route, we’re also going to encounter async exceptions (structured exceptions) on our quest for a better crash. We’ll poke into these mechanisms and see how we can leverage them in our application error handling. Did I mention threads? Routing exceptions between threads… oh my!

Time to update.
CLion 2022.2 Released
by Anastasia Kazakova
From the article:
Today we’re announcing the CLion 2022.2 release! To update to the new version, you can use the Toolbox App or a snap package (on Ubuntu), download the installer from our website, or apply the patch update to upgrade from version 2022.1.
The CLion 2022.2 release improves CMake integration. The Quick Documentation popup has become a useful source of knowledge about your C++ and CMake code. Enhanced static and dynamic code analysis, better debugger integration, and performance improvements for remote and Docker toolchains help you develop more productively. Read on for more details and give CLion 2022.2 a try...
