Working Draft, Technical Specification for C++ Extensions for Parallelism

by Jared Hoberock

Excerpt:

This Technical Specification describes requirements for implementations of an interface that computer
programs written in the C++ programming language may use to invoke algorithms with parallel execution.
The algorithms described by this Technical Specification are realizable across a broad class of computer
architectures.

... The goal of this Technical Specification is to build widespread existing practice for parallelism in the C++ standard algorithms library.

Improvements to std::future and Related APIs

by Niklas Gustafsson, Artur Laksberg, Herb Sutter, Sana Mithani

Excerpt:

This proposal is an evolution of the functionality of std::future/std::shared_future. It details additions which can enable wait free compositions of asynchronous operations.

This document supersedes N3784. Several typos in the code samples have been fixed, and a small editorial change made in the Technical Specification section.

Improving the Verification of C++ Programs

by Michael Price

Excerpt:

Following is a list of ideas to serve as a starting point for further discussion. They are ordered roughly in their perceived difficulty/impact on the language and tools.

  • Capabilities for better static_assert messages
  • Better support for verifying API design decisions (i.e. testing compile-time failures)
  • Discrete classification of causes of ill-formedness
  • Better source code contextual information capabilities (as called for by Reflection study group)
  • A std::test_exception (bikeshed) type to serve as a basis for...
  • An full-featured assertion library
  • Registration of code to be run during verification
  • Automated generation of verification programs

Improved insertion interface for unique-key maps

by Thomas Köppe

Excerpt:

The existing interface of unique-keyed map containers (std::map, std::unordered_map) is slightly underspecified, which makes certain container mutations more complicated to write than necessary. This proposal is to add new specialized algorithms:

  • emplace_stable(): if the key already exists, does not insert and does not modify the arguments.
  • emplace_or_update(): inserts or updates the mapped element if the key already exists.

C++ Standard Evolution Active Issues List (Revision R05)

C++ Standard Evolution Completed Issues List (Revision R05)

C++ Standard Evolution Closed Issues List (Revision R05)

by Ville Voutilainen

Excerpt:

The purpose of this document is to record the status of issues which have come before the Evolution Working Group (EWG) of the INCITS PL22.16 and ISO WG21 C++ Standards Committee. Issues represent potential defects in the ISO/IEC IS 14882:2003(E) document, and proposed extensions to it.
