Threads with preempt disabled will run until they either: a) encounter a thread blocking region b) call Thread.pass This allows native threads to act cooperatively without being interrupted by other threads. Thread#preemptible? => true or false Thread#preemptible = (true|false) I plan to implement timer-based switching to "auto-fiber/threadlet/thriber/whatever-name" [Feature #13618] to minimize migration costs from Thread. However, I think based on the discussion in [Feature #13618]; having predictability of non-preemptible threads is beneficial. So implement it for native Thread for now. I will unify the behavior of [Feature #13618] with existing Thread. I think green/native threads can be unified under Thread class similar to how Fixnum/Bignum are both "Integer". ---Files-------------------------------- 0001-thread-allow-disabling-preempt.patch (4.16 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
