Running console commands with required input with a non-TTY stdin causes an infinite loop

[mattgrayisok]

Description

Running any console commands which have a required or validated input that isn't included as a command line argument causes a prompt to appear asking the user for input. When this happens with a non-TTY stdin the prompt is immediately returned as empty which triggers a validation error and re-prompt resulting in an infinite loop.

This has caught me out in 2 places:

• Running commands from CI
• Running commands in docker without attaching a TTY

EDIT:

I stopped being lazy and tracked down the bug. It's actually in Yii here:

https://github.com/yiisoft/yii2/blob/master/framework/helpers/BaseConsole.php#L800

(Nice to see an oldschool goto in there)

So maybe a Yii2 PR would be better than overriding the prompt() method...

Steps to reproduce

1. echo "loop" | ./craft install

Additional info

• Craft version: 3.4
• PHP version: 7.3

Yeah, this would need to be addressed in Yii.
