Feature #17369
Updated by ioquatix (Samuel Williams) over 3 years ago
https://github.com/ruby/ruby/pull/3853 https://github.com/ruby/ruby/pull/3852 This PR introduces optional hooks to the scheduler interface for handling `Process.wait`, `Kernel.system` and other related methods (`waitpid`, `wait2`, etc). It funnels all methods through a new interface `Process::Status.wait` which is almost identical to `Process.wait` except for several key differences: - The return value is a single instance of `Process::Status`. - It does not set thread local `$?`. This is necessary for keeping the scheduler interface simple (and side effects are generally bad anyway).
