Re: Fibers in Ruby 1.9?
Francis, As I understand it, external iterators are implemented on top of fibers. And external iterators are working for me in Linux. So the fibers must be working. (I've posted external iterator examples at http://www.davidflanagan.com/blog/2007_08.html#000138 but I haven't figured out the Fiber API yet, so I haven't tested Fibers directly yet.) According to Wikipedia's entry on Fibers, they can be implemented in Posix with getcontext,setcontext,swapcontext from ucontext.h. I don't know anything about it. I haven't done that kind of low-level hacking since the days of setjmp/longjmp. I doesn't look to me, however, as if Ruby's implementation does that. Fibers are in cont.c, along with continuations. I haven't figured that code out yet, but I'm guessing that they're implemented on top of (or with the same techniques as) Continuations.
