rename fails on Windows PHP 8.1 if the target file is being executed

Description

The following code:

<?php
// file: bug.php

$content = file_get_contents(__FILE__);
file_put_contents('newfile.php', $content."\n//");
var_dump(rename('newfile.php', __FILE__));

Resulted in this output:

PHP Warning:  rename(newfile.php,C:\Users\John\projects\test\bug.php): Access is denied (code: 5) in C:\Users\John\projects\test\bug.php on line 6

Warning: rename(newfile.php,C:\Users\John\projects\test\bug.php): Access is denied (code: 5) in C:\Users\John\projects\test\bug.php on line 6
bool(false)

But I expected this output instead:

bool(true)

This code mimics how Composer self updates (https://getcomposer.org/doc/03-cli.md#self-update-selfupdate-) and has obviously worked for many years, but is broken on Windows PHP 8.1: https://github.com/composer/composer/issues/10444

Note that on Composer 2 we now use copy on Windows (to get around potential permission issues in UAC protected locations) and this still works on PHP 8.1, but Composer 1 uses rename (as do all non-Windows platforms on all Composer versions).

Fortunately, this appears to be a Windows only thing, as per this demo: https://github.com/johnstevenson/php-rename-bug/actions/runs/1669358275

PHP Version

PHP 8.1.0

Operating System

Windows 10

Commencez par reproduire le script bug.php fourni sous Windows 10 avec PHP 8.1, puis examinez l’implémentation de rename et le travail en cours dans la pull request #9351. C’est terminé lorsque le self-rename renvoie bool(true) sous Windows sans avertissement d’accès refusé, tout en préservant le comportement décrit pour les autres plateformes.
