C++26 specifies an interface for asynchronous operations. Previous presentations have shown how to utilize such interfaces to compose work based on concurrent computations and use native sender interfaces to deal with networking. Since there were asynchronous interfaces that predated the C++ interface, it is desirable to integrate these into the new ecosystem. This presentation shows how to take an existing asynchronous interface and add a sender interface for full integration with std::execution. My concrete plan is to combine a networking interface for HTTP requests with a PostgreSQL database to respond to these requests. The whole system is meant to use […]
The C++26 specification includes the sender/receiver framework for dealing with asynchronous operations. It defines a vocabulary, as well as various algorithms and utilities using this vocabulary. The current specification doesn't include a matching coroutine task class template, though it is expected that most users would use coroutines to actually use the facilities. This presentation discusses various aspects for creating a coroutine task suitable for many needs, including: - The basic operation of a sender/receiver aware task - Scheduler affinity and why it is important - Allocator support for the coroutine frame - Providing an environment to child operations - Propagating […]
