realpath() and SplFileInfo::getRealPath inside Phar

Description

I'm trying to include packages in my phar but many of them use realpath to files inside the Phar which spits out false instead of a path; breaking things. If the behavior was to return the same path when the path starts with phar:// it would just work.

The following code:

make_phar.php

<?php
$phar = new Phar('test.phar');
$phar->addFile('test.php');
$phar->setDefaultStub('test.php');
$phar->stopBuffering();

test.php

<?php
var_dump(
    __FILE__,
    realpath(__FILE__), 
    (new SplFileInfo(__FILE__))->getRealPath(),
);

php test.php && php make_phar.php && php test.phar

Resulted in this output:

string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"
bool(false)
bool(false)

But I expected this output instead:

string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"

Operating System

No response

Inizia eseguendo make_phar.php, test.php e il comando php test.phar fornito per riprodurre i risultati errati di realpath() e SplFileInfo::getRealPath(). Traccia la gestione del filesystem di PHP e Phar coinvolta in queste chiamate. Il lavoro è completo quando entrambe le funzioni restituiscono il percorso phar:// mostrato nell'output previsto, lasciando invariati i risultati esistenti non relativi a Phar.
