Backport #8436: __dir__ not working in eval with binding

• Status: Closed
• Assignee: nagachika (Tomoyuki Chikanaga)

[Gat (Dawid Janczak)]

Hello,
I think I might have found a bug concerning the new dir method.

Given binding (e.g. current top level binding) I would expect dir to return the directory I'm in, similarly to how FILE with binding does. Instead it returns nil.

I think I have found the solution, but since this is my first modification of Ruby code it might be inaccurate and not work in some cases. I hope it points to the right location though.
Please see attached patch along with a testcase showing the problem.

I also had to modify another testcase to use realpath when checking dir functionality, please check if it's correct.
