Recursive search on a linux system (1 thread) from root including subdirectories causes 8.4 GB Ram and counting

Description

The following code:

<?php
/**
     * @throws DirectoryCreateException
     * @throws Exception
     */
    public function search($flags, $options): void
    {
        $object = $this->object();
        $data = new Data($object->data());
        if(!property_exists($options, 'name')){
            throw new Exception('Option -name not set');
        }
        if(!property_exists($options, 'directory')){
            throw new Exception('Option -directory not set');
        }
        $dir = new Dir();
        $list = $dir->read($options->directory, true);
        foreach($list as $file){
            if($file->name === $options->name){
                breakpoint('match');
            }
        }
        breakpoint($list);
    }

Resulted in this output:

15625 root      20   0 9139760   8.5g   2304 R  99.7  55.0  15:11.97 php
15625 root      20   0   13.3g  13.0g   2304 R 100.0  83.9  24:48.36 php

But I expected this output instead:

15625 root      20   0 9139760   1.5g   2304 R  99.7  3.0  15:11.97 php

What i meant is this:

I keep a list of all files on the system and searches for a match.
I can create a search from root directory and go 1 subdirectory at a time but my opinion is that searching on a root device should work like a charm without complicating stuff too much...

Commencez avec la commande CLI fournie, PHP 8.4.12 et l’environnement Debian bookworm, puis reproduisez l’augmentation de la mémoire tout en traçant l’appel à Dir::read de l’application. Isolez la question de savoir si le comportement vient de PHP ou du code de l’application et documentez un cas minimal reproductible ainsi que le comportement attendu de la mémoire.
