Hi all! In the wild people are doing all kinds of different things with Qt on the network side. And there are some obvious issues with that given the "callback" nature of Qt networking code.
One can see different examples of people over the years dealing with that: http://cukic.co/2016/01/17/asynqt-framework-making-qfuture-useful https://github.com/KDE/kasync http://qasync.henrikhedberg.com https://github.com/mhogomchungu/tasks https://gist.github.com/legnaleurc/1038309 Since we are also using Qt a lot on the server side I'm curious what is the progress from the Qt side on that given that coroutines will come to C++ ( http://en.cppreference.com/w/cpp/experimental) We were using Boost and as we were using Qt for clients decided we could also do server parts in Qt as well. This is all fine and I enjoyed it, but boost has futures, promises and coroutines as well, which is nice, since we also have backends in Node.js where we employ identical patterns. So I've been waiting for 2 years now to see what will come up from Qt and I don't see much about that changing. Heck, QAsync tackled this in 2011. Will Qt "embrace" coroutines from standard? Will they come up with something of their own? Should we abandon Qt for networking? Should we use something of our own? One possible way currently is to use QtConcurrent (badly I guess) and wrap everything into QtConcurrent::run, which, for example, for QNetworkRequest means first converting it to sync code using local event loop which is again not recommended. I expect that everybody is up to date and know about callbacks/coroutines/futures/promises/generators these days but for others here are some examples that explain it better than I can: http://www.boost.org/doc/libs/1_63_0/libs/coroutine2/doc/html/coroutine2/motivation.html https://msdn.microsoft.com/en-us/magazine/mt573711.aspx https://blogs.msdn.microsoft.com/vcblog/2016/04/04/using-c-coroutines-to-simplify-async-uwp-code Thanks, Petar
