Cannot Rename Page with Case-Only Change

[gomaaz]

Bug Description

When a user attempts to rename an existing page by only changing the capitalization of the page name (e.g., from lowercase to uppercase), the system throws a validation error and the rename operation is not completed.

The error message displayed is: "New and old name are the same."

This indicates that the name validation or renaming logic is performing a case-insensitive comparison, incorrectly identifying the case-changed name as identical to the original name.

Steps to Reproduce

1. Create a new page with a name in all lowercase (e.g., testpage).
2. Navigate to the page's rename/settings functionality.
3. Attempt to change the page name by only altering the case (e.g., changing testpage to TestPage or TESTPAGE).
4. Try to save the changes.

Expected Behavior

The page name should be successfully updated to the new capitalization (e.g., TestPage). The system should treat names that differ only in case as distinct, allowing the rename to proceed.

Actual Behavior

The system rejects the change and displays the error message: "New and old name are the same."

Works okay for me.

Have you enabled RETAIN_PAGE_NAME_CASE?
Is your filesystem case-sensitive?

Without RETAIN_PAGE_NAME_CASE enable, you can influence the capitalization by changing the the first header of the page:

# RanDom CaPitalization

will make the title render

Have you enabled RETAIN_PAGE_NAME_CASE?
Is your filesystem case-sensitive?

I have tried it with both false and true.
You can't change the case afterwards with file renaming.
My filesystem is not case sensitive.

Maybe we again don't understand what exactly you're doing :)
Can you reproduce it on https://demo.otterwiki.com/ (just make sure that "Retain page name case" is enabled in the settings)?
