Support for green threads in std.concurrency is almost
complete. I should really just do the last bit of work. I
imagine you could try out the idea now though by using the
messaging in vibe.d, since every connection is a fiber.
Can you provide any more details? Right now vibe.d uses own
implementation
(https://github.com/rejectedsoftware/vibe.d/blob/master/source/vibe/core/concurrency.d)
- trying to replace with with updated Phobos one can be a good
real-world test for such enhancement.
My motivation was to make std.concurrency work with vibe.d. And
more generally, to start testing fiber-based concurrency in
general. The basic idea is to make certain low-level parts of
std.concurrency be pluggable, so the same API can be used on top
of different threading schemes. You basically just need to
implement this interface:
interface Scheduler {
void start(void delegate() op); // start the scheduler
void spawn(void delegate() op); // spawn a new thread
void yield(); // for send and receive to yield to allow green
threading
Condition newCondition(Mutex m); // the condition will
notify/wait for new messages
}
I should have a sample implementation working for green threads
shortly. Then I need to submit a bugzilla ticket and sort out a
pull request.
