Issue #6117 has been updated by ko1 (Koichi Sasada). Target version set to 2.0.0 Please give me a time. ---------------------------------------- Bug #6117: Transfers allowed into Fibers that have resumed into other fibers https://bugs.ruby-lang.org/issues/6117#change-31958 Author: loganb (Logan Bowers) Status: Assigned Priority: Normal Assignee: ko1 (Koichi Sasada) Category: Target version: 2.0.0 ruby -v: ruby 2.0.0dev (2012-03-06) [x86_64-darwin11.3.0] =begin Consider the following code: require 'fiber' def foo order = [] main_fiber = Fiber.current a = Fiber.new do order << 2 x = Fiber.new do order << 4 main_fiber.transfer order << 6 end order << 3 x.resume order << 7 end order << 1 a.transfer order << 5 a.transfer order << 8 end It produces output: [1, 2, 3, 4, 5, 7, 8] Note: the missing 6. I'd expect either the array to be 1-8 OR for an exception to be raised after 5 when the main fiber attempts to transfer into a again. Either it shouldn't be possible to transfer into a Fiber that is blocked resuming another Fiber, OR it should automatically resume the sub-Fiber. =end -- http://bugs.ruby-lang.org/
