realpath() on MacOSX doesn't normalize the case of characters

Hello, I reported this bug one year ago (https://bugs.php.net/67220) and it is now closed as "not a bug". I'd like this to be reconsidered. The documentation of realpath() says: > realpath() expands all symbolic links and resolves references to '/./', > '/../' and extra '/' characters in the input path ***and returns the > canonicalized absolute pathname***. > the last part of this description is IMO what qualifies this behavior on MacOSX as a bug. I'm asking for this now because I spend many hours on Syfony trying to find an efficient workaround, and this is far from easy. Here is the fastest we found (it's a mix of scandir()+getcwd()+caching): https://github.com/symfony/symfony/pull/15443 If realpath were behaving on OSX the same as it does on Windows (and Linux), I could remove 60 lines of wtf lines. Do anyone else agree? Regards, Nicolas
