Issue #17369 has been updated by nobu (Nobuyoshi Nakada). Please file a new issue for fiber-local `$?`. ---------------------------------------- Feature #17369: Introduce non-blocking `Process.wait`, `Kernel.system` and related methods. https://bugs.ruby-lang.org/issues/17369#change-94216 * Author: ioquatix (Samuel Williams) * Status: Assigned * Priority: Normal * Assignee: ioquatix (Samuel Williams) ---------------------------------------- https://github.com/ruby/ruby/pull/3853 This PR introduces optional hooks to the scheduler interface for handling `Process.wait`, `Kernel.system` and other related methods (`waitpid`, `wait2`, etc). It funnels all methods through a new interface `Process::Status.wait` which is almost identical to `Process.wait` except for several key differences: - The return value is a single instance of `Process::Status`. - It does not set thread local `$?`. This is necessary for keeping the scheduler interface simple (and side effects are generally bad anyway). -- https://bugs.ruby-lang.org/ Unsubscribe:
