Previous dev-meeting (March), there is no objection to change the return value of `Mutex#sleep`. > matz: agreed to change the return value of Mutex#sleep. > naruse: agreed to change in Ruby 3.1 because this is so detail Congrats! ---------------------------------------- Bug #16608: ConditionVariable#wait should return false when timeout exceeded https://bugs.ruby-lang.org/issues/16608#change-91579 * Author: shugo (Shugo Maeda) * Status: Assigned * Priority: Normal * Assignee: nobu (Nobuyoshi Nakada) * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- The following program prints `false` on Ruby 1.8, but `true` on Ruby 1.9 or later. ``` require "monitor" m = Monitor.new c = m.new_cond m.synchronize { p c.wait(0.1) } ``` However, it's not critical because most programs check the condition after wait. -- https://bugs.ruby-lang.org/ Unsubscribe:
