Bitesize Modern C++ : std::array--Glennan Carnie

Some details about arrays in C++:

Bitesize Modern C++ : std::array

by Glennan Carnie

From the article:

C++98 inherited C’s only built-in container, the array. Arrays of non-class types behave in exactly the same way as they do in C. For class types, when an array is constructed the default constructor is called on each element in the array...

A brief introduction to C++’s model for type- and resource-safety -- Stroustrup, Sutter, Dos Reis

By Blog Staff | Oct 7, 2015 07:27 AM | Tags: None

A new paper has been posted to the CppCoreGuidelines /docs folder:

A brief introduction to C++’s model for type- and resource-safety 

by Bjarne Stroustrup, Herb Sutter, and Gabriel Dos Reis

The goal of the paper is to provide a readable high-level overview of C++'s existing resource handling model and the extension of that for type safety that was announced at CppCon. A more detailed treatment of lifetime safety (avoiding leaks and dangling) can be found in Herb Sutter's CppCon talk (YouTube) (Channel 9) and Lifetime paper.

From the paper:

Abstract

You can write C++ programs that are statically type safe and have no resource leaks. You can do that without loss of performance and without limiting C++’s expressive power. This model for type- and resource-safe C++ has been implemented using a combination of ISO standard C++ language facilities, static analysis, and a tiny support library (written in ISO standard C++). This supports the general thesis that garbage collection is neither necessary nor sufficient for quality software. This paper describes the techniques used to eliminate dangling pointers and to ensure resource safety. Other aspects – also necessary for safe and effective use of C++ – have conventional solutions so they are mentioned only briefly here.

The techniques and facilities presented are supported by the Core C++ Guidelines [Stroustrup,2015] and enforced by a static analysis tool for those [Sutter,2015].

AllocatorAwareContainer: Introduction and pitfalls...--Jonathan Müller

By Adrien Hamelin | Oct 5, 2015 09:31 AM | Tags: c++11 advanced

An interesting article about some dangerous allocators:

AllocatorAwareContainer: Introduction and pitfalls of propagate_on_container_XXX defaults

by Jonathan Müller

From the article:

While I was writing the std_allocator adapter of foonathan/memory I've learned some not so well-known facts about the STL Allocator and AllocatorAwareContainer concepts I'd like to share. Let's take a deep breath and dive in into an aspect of the STL containers that isn't that well covered: Allocator storage.

I will explain the comparison properties of Allocators, show the C++11 propagate_on_container_XXX traits and how the combination of the two can lead to an unnecessary pessimization and a probably not widely known case of undefined behavior...

From the article:

I used to do overviews on all papers for a meeting, and when I find the time, I will do this for upcoming meetings again. I will try to post a best-of later, with all the good stuff on concepts, modules and more later. Currently I'm to busy, I just got back from CppCon, and will go to the Qt World Summit next week (meet me there!).

So, in the mean time you can take take a look for yourself, as what follows is the list off all papers submitted this year, sorted by mailings and then subgroups. My awesome paper crawler tool did finally its job correct...
