Red Hat at the ISO C++ Standards Meeting (November 2017): Parallelism and Concurrency

by Torvald Riegel

From the article:

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in November 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. SG1 had a full schedule as usual, with Executors, Futures, and deferred reclamation mechanisms (e.g., RCU) being major discussion topics. We also started to track the state of proposals and topics we will need to discuss in a publicly accessible bug tracker...

C++17 Feature Removals And Deprecations--Stephan T. Lavavej

This is about visual studio, but this is also about how the deprecated mechanisms work.

C++17 Feature Removals And Deprecations

by Stephan T. Lavavej

From the article:

Technology advances by inventing new ways of doing things and by discarding old ways. The C++ Standardization Committee is simultaneously adding new features and removing old features at a gradual pace, because we’ve discovered thoroughly better ways of writing code. While feature removals can be annoying, in the sense that programmers need to go change old codebases in order to make them conform to new Standards, they’re also important. Feature removals simplify the Core Language and Standard Library, avoiding the doom of accreting complexity forever. Additionally, removing old features makes it easier to read and write code. C++ will always be a language that offers programmers many ways to write something, but by taking away inferior techniques, it’s easier to choose one of the remaining techniques which are more modern...

5 ways how unique_ptr enhances resource safety in your code -- Bartlomiej Filipek

Examples where unique_ptr shines:

5 ways how unique_ptr enhances resource safety in your code

by Bartlomiej Filipek

From the article:

While shared_ptr and weak_ptr are more complex, unique_ptr seems to be a perfect replacement for owning raw pointers. Not to mention is the fact that this pointer type is mostly a compile time “wrapper” and it cost almost nothing in the runtime.

Your own type predicate--Andrzej KrzemieĊ„ski

A very detailled and complete article to start playing with template predicates!

Your own type predicate

by Andrzej Krzemieński

From the article:

In this post we will see how to define a type trait or a type predicate or a meta-function that would allow us to check at compile time whether a type exposes an interface that we need. That is, we want to check if a given type T has:

  • nested typename result_type,
  • static member function set_limit that takes one argument of type int,
  • member function get_result that returns type const result_type& and that is declared not to throw exceptions...
