Issue #17482 has been updated by ko1 (Koichi Sasada). b2674c1fd725b43adf51af7935c780359d70c2a4 should be backported too. ---------------------------------------- Bug #17482: Ractor.receive doesnt accept Ctrl+C under some condition https://bugs.ruby-lang.org/issues/17482#change-90271 * Author: riskwa (riskwa anon) * Status: Closed * Priority: Normal * Assignee: ko1 (Koichi Sasada) * ruby -v: ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: REQUIRED ---------------------------------------- When I run this script, Ctrl+C doesn't work. Waiting forever on #4 is fine, but I think Ctrl+C should work. ``` ruby r = Ractor.new() { # sleep 1 #1 File.open(__FILE__){ } #2 } # sleep 1 #3 p Ractor.receive #4 ``` When I comment out #2, Ctrl+C works. When I comment in #1 and/or #3, Ctrl+C works. In my environment, it's reproducable in 100%. My environment is: WSL2 ubuntu 5 4.19.128-microsoft-standard #1 i5-10400 6core -- https://bugs.ruby-lang.org/
