How to Write Safe and Expressive Multi-Threaded Code in C++11

by Louis-Charles Caron

I started writing multi-threaded code two years ago. Two years and one day ago, I would start sweating at the sound of the the words thread and mutex. But after literally a few days of practice (and, I admit, a 3-day course on multi-threading and C++11), I figured the basic principles are quite understandable.

Typical multi-thread problems can be solved by using a handful of tools. Admittedly, complex problems are even more complex when they appear in multi-threaded code, but I did not happen to run into those yet.

Since C++11, one now finds the necessary multi-threading tools in the C++ standard library. Finally! We can write multi-threaded code in pure C++.

The multi-threading part of the C++11 library is functional: it is simple and to the point. However, it is nearly impossible to write clear and expressive multi-threaded code using only the C++11 tools. And when multi-threaded code is not clear, it tends not to be safe.

In this article, I introduce some multi-threading tools you will find in the C++11 standard library through a code example. Although simple, this example will clearly demonstrate the shortcomings of the C++11 standard library. Then, I present safe: a small header-only C++11 library I designed to make my multi-threaded code more expressive, and ultimately safer...

Handling errors is canceling operations

by Andrzej Krzemieński

I actually covered this topic before, in this post, but given my recent experience I feel it needs reiterating and a bit of restructuring. It boils down to the observation that any error handling I have encountered — be it error codes, errno, exceptions, error monad — is about canceling operations that depend, directly or indirectly, on the function that reported failure. This has some consequences on how we look at our program flow and what principles we should follow when responding to failures in our programs...

The Rule of Zero in C++

by Jonathan Boccara

Now that we’re clear on the Compiler-generated Functions, the Rule of Three and the Rule of Five, let’s put this to use to reflect on how to use the “= default” feature to have expressive and correct code...
