Issue #21091 has been updated by shyouhei (Shyouhei Urabe).
Status changed from Open to Third Party's Issue
There's not much thing we can do to this situation. Your file system opted to provide us multiple file paths for an identical content. That's how your operating system is designed to work. Ruby doesn't prevent you from shooting yourself in foot.

Bug #21091: recursive require not detected on case insensitive filesystem
https://bugs.ruby-lang.org/issues/21091#change-111666
* Author: rrotter (Ryan Rotter)
* Status: Third Party's Issue
* ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [arm64-darwin24]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
On case insensitive filesystems `require`ing a file from itself causes the file to be `require`d twice if the initial `require` and the `require` inside the file have different capitalization.
I expect the second `require` to return false, and not execute the file a second time.
```
~ % cat /tmp/foo.rb
puts "loading #{__FILE__}"
require "/tmp/foo"
SOME_GLOBAL = "foobar".freeze
~ % ruby -r/tmp/FOO
loading /tmp/FOO.rb
loading /tmp/foo.rb
/tmp/FOO.rb:3: warning: already initialized constant SOME_GLOBAL
/tmp/foo.rb:3: warning: previous definition of SOME_GLOBAL was here
```
This is on macOS 15.1.1, using the default case-insensitive APFS, and ruby 3.4.1.
