Issue #19056 has been updated by Eregon (Benoit Daloze). Probably not, but I also think net-http shouldn't use it. There is overhead to e.g. call Addrinfo#inspect (or #to_s) in your screenshot above. Also for such logging to be useful one most likely needs string interpolation, which means string allocations even when the annotations are not used. And non-Fiber users probably have little to no use for those annotations. ---------------------------------------- Feature #19056: Introduce `Fiber.annotation` for attaching messages to fibers. https://bugs.ruby-lang.org/issues/19056#change-103419 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal * Assignee: ioquatix (Samuel Williams) ---------------------------------------- It's useful to know what a fiber is doing especially when they have a temporal execution (i.e. sockets connecting vs connected, binding vs accepting, queue popping, etc) Let's introduce `Fiber.annotate` and `Fiber#annotation` for logging a short message attached to Fibers. ```ruby Fiber.annotate "Counting to 10" 10.times{|I| puts I} # Fiber.current.annotation => "Counting to 10" ``` Pull Request: https://github.com/ruby/ruby/pull/6554 ---Files-------------------------------- clipboard-202210160132-n7lzp.png (865 KB) -- https://bugs.ruby-lang.org/
