I've committed really basic Fiber support on trunk. It passes the simple
tests from YARV's test_fiber (also committed, with bits commented out),
and appears to run all demo code I've found online. The following parts
aren't implemented yet:
- all error-handling
- Fiber.transfer (I wasn't clear how this is supposed to work, but it
will probably be simple to do)
Also, two tests in test_fiber that construct a thousand or more fibers
are commented out, because my implementation uses native threads (and
the 10000-fiber test never seemed to return). This isn't to say it's not
possible to support that many fibers with this impl, but it won't be cheap.
Anyway, have a look at the code. I've asked for clarification or a
pointer to Fiber spec docs on ruby-core list...we can fill out the rest
of the behavior then.
