Spurious "stty: standard input" output on stderr from TTY::Screen.size when running on Alpine Linux within a PTY.spawn process from within rspec about tty-screen HOT 2 CLOSED

Hi Tero,

Thanks for this detailed report! I would agree with your suggestion to suppress stderr output. Would it possible for you to change this line to:

result = system(*args, out: out.path, err: File::NULL)

and test on your local system. It would be really helpful if you could fork the project and submit PR in case the issue is solved!

As far as your issues with Alpine Linux vs Ubuntu go, I would think it is due to PTY module implementation. The PTY uses system specific pseudo terminal which may have very different behaviour between platforms in my experience. Also, rspec detects if it is running interactively or not and changes behaviour accordingly. I'm would be inclined to think that the real culprit is the PTY module and changing it to use process spawning would solve the issue. However, I'm happy to have this issue resolved in tty-screen to make it more robust for any conditions.

Released v0.6.4 with your patch - thanks!
