Issue #21505 has been updated by Eregon (Benoit Daloze). `Kernel#exit` is basically just `raise SystemExit`, does it mean any exception in a Ractor hangs? IOW, I don't think it should be disallow because `exit` is just an Exception. ---------------------------------------- Bug #21505: [Ractor] calling exit from non-main ractor will hang if main ractor waits on it https://bugs.ruby-lang.org/issues/21505#change-113967 * Author: luke-gru (Luke Gruber) * Status: Open * Assignee: ractor * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- ```ruby r = Ractor.new do exit end r.join # hangs ``` Should `exit` be allowed in ractors? It would be easiest to disallow, as the code might be tricky if we allow it. -- https://bugs.ruby-lang.org/
