So, about this article and behavior: 1. This behavior doesn't seem "well-known restriction", there is no explanation or details (why?) in the article or somewhere. 2. Article highlights that even `KILL` signal works incorrect on Windows (but I guess it should be a separate issue). 3. Article suggests system command instead of Ruby method. 4. There is should be consistency and understandable behavior in Ruby, even in Windows (as I know, Ruby should works on Windows). So, either `Signal.list` should return only `KILL` and something else working, or `Process.kill` should works with `TERM` and other signals. Anyway, `Signal.list` output and `Process.kill` input should be synced. ---------------------------------------- Bug #17820: `Errno::EINVAL` from `Process.kill` with available signal on Windows https://bugs.ruby-lang.org/issues/17820#change-91660 * Author: AlexWayfer (Alexander Popov) * Status: Open * Priority: Normal * ruby -v: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x64-mingw32] * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- Hello. I've installed Ruby on Windows via [Chocolatey](https://community.chocolatey.org/packages/ruby). I receive `Errno::EINVAL` from `Process.kill` with almost every signal. Only `0` seems working. `TERM` (`15`), `INT` (`2`) ��� don't. Although they're in `Signal.list` output: ![](clipboard-202104222051-b64xq.png) ---Files-------------------------------- clipboard-202104222051-b64xq.png (63.9 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
