Issue #19691 has been reported by MSP-Greg (Greg L). ---------------------------------------- Bug #19691: Case insensitive file systems, require filename casing https://bugs.ruby-lang.org/issues/19691 * Author: MSP-Greg (Greg L) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I don't know what I think of this (expected or bug), but recently in a forum I saw an issue that I don't recall accidentally doing myself. An equivalent example: ``` ruby -rsingleton -rSingleton -e "puts 'case issue'" ``` Note the change of casing with `Singleton`. On case insensitive file systems, the above will double load the file, which errors. Obviously, on case sensitive file systems, it errors with `cannot load such file -- Singleton` So, options are: A. No change to current behavior, which I'm fine with. B. If the OS is case insensitive, don't reload the file, and maybe a warning that `Singleton` and `singleton` are equivalent. -- https://bugs.ruby-lang.org/
