Concurrency TS Editor's Report, May 2014

Overview

N3970 is the Concurrency TS Draft. It is based on D3904 with the following changes as per LEWG feedback:

• The then method now implements auto-unwrapping, obviating the need for unwrap.
• The type thread_executor renamed to thread_per_task_executor.
• Fixed an issue where is_ready was incorrectly spelled as ready in some parts of the document.
• The method when_any_swapped has been renamed to when_any_back.

The new document also incorporates feedback from the following individuals:

• Agustín K-ballo Bergé pointed out several instances where reference decay was handled incorrectly, as well as numerous typos.
• Vicente J. Botet Escriba found that it is underspecified how an exception thrown from a continuation is propagated into the returned future, and also pointed out a number of inaccuracies in the document, most of which have been fixed.
• Detlef Vollmann suggested using chrono::steady_clock instead of chrono::system_clock in the add_after method.

Additionally, the document has been fully reformatted using the html-doc-framework and many formatting and editorial issues were fixed.
