it's not easy to synchronize two event dispatcher/schedulers, e.g. boost.asio's io_service + boost.fiber's fiber-scheduler Re: [Boost-users] [fiber] Asio autoecho example crashes (VS 2015 u3) DePizzottri

Hi, I am using the Boost.Fiber <-> Boost.Asio coupling via the boost::fibers::asio::round_robin scheduler, and I am trying to relaunch an asio io_service, that has previously been stopped. I've build fiber as static library (BOOST_FIBERS_SOURCE, BOOST_FIBERS_STATIC_LINK) and link the app with boost 1.65.1 shared libs (debug, valgrind=on, gcc 5.4.1, linux x64). olk added a commit that referenced this issue Jan 4, 2018 Overview. As noted in the Scheduling section, by default Boost.Fiber uses its own round_robin scheduler for each thread. To control the way Boost.Fiber schedules ready fibers on a particular thread, in general you must follow several steps. Gitiles.

Boost.Fiber provides the fiber manager, but the scheduler is a customization point. Ok, there were a couple of things I missed, first, my conclusion was based on misunderstanding of how stuff works in boost::fiber The line in the constructor mentioned in the question bf::use_scheduling_algorithm(2); Boost.Fiberprovides a number of ways to wait for a running fiber to complete. You can coordinate even with a detached fiber using a mutex, or condition_variable, or any of the other synchronization objectsprovided by the library. Boost fibers are scheduled cooperatively. When each fiber yields control, the fiber manager picks the next fiber for scheduling.

Boost.Fiber provides a framework for micro-/userland-threads (fibers) scheduled cooperatively. The API contains classes and functions to manage and synchronize fibers similiarly to standard thread support library. Each fiber has its own stack.

- When a fiber blocks, it implicitly passes control to the fiber scheduler. Coroutines have no scheduler because they need no scheduler. There is an issue. The assert in scheduler.cpp line 202 (BOOST_ASSERT( ! ctx->wait_is_linked() ))is firing after condition_variable wait_until times out.
