$config in AwsS3V3Adapter copy function is null/empty

[srabouin]

Bug Report

Q	A
Flysystem Version	3.24.0
Adapter Name	AwsS3V3Adapter
Adapter version	3.24.0

Summary

I am using Laravel 9.52.16 and the S3 driver to upload/move files to Cloudflare R2. The upload is in a temporary folder, and then I move it to the final folder. The move function is the issue.

In the config, I have set visibility to 'private' to prevent calling GetObjectAcl that is not supported by R2, but after upgrading to 3.24.0 it gave the error that GetObjectAcl is not supported.

During troubleshooting I just dumped the $config variable when the copy function is called here

flysystem/src/AwsS3V3/AwsS3V3Adapter.php

Line 418 in b25a361

$visibility = $config->get(Config::OPTION_VISIBILITY);

and found it was null/empty. Reverting to 3.15.0 and everything is working fine again.

It's possible I missed something?

How to reproduce

R2 config:

'disks' => [
        'r2' => [
            'driver' => 's3',
            'key' => env('CLOUDFLARE_R2_ACCESS_KEY_ID'),
            'secret' => env('CLOUDFLARE_R2_SECRET_ACCESS_KEY'),
            'region' => env('CLOUDFLARE_R2_REGION'),
            'bucket' => env('CLOUDFLARE_R2_BUCKET'),
            'disable_asserts' => true,
            'visibility' => 'private',
            'endpoint' => env('CLOUDFLARE_R2_ENDPOINT'),
            'url' => env('CLOUDFLARE_R2_URL'),
            'domain' => env('CLOUDFLARE_R2_FILE_DOMAIN', ''),
            'domain_original' => env('CLOUDFLARE_R2_ORIGINAL_DOMAIN', ''),
            'throw' => true,
        ],
]

Single line of code:

Storage::disk('r2')->move($from, $to);

Actual error, removed irrelevant lines:

The issue also exists with the copy function when used with R2, with $visibility being null, and throwing League\Flysystem\UnableToRetrieveMetadata, where GetObjectAcl not implemented appears too.

Storage::disk('r2')->copy($sourcePath, $targetPath);

Will run this code:

public function copy(string $source, string $destination, Config $config): void
    {
        try {
            $visibility = $config->get(Config::OPTION_VISIBILITY);

            if ($visibility === null && $config->get(Config::OPTION_RETAIN_VISIBILITY, true)) {
                $visibility = $this->visibility($source)->visibility();
            }
        } catch (Throwable $exception) {
            throw UnableToCopyFile::fromLocationTo(
                $source,
                $destination,
                $exception
            );
        }
    // ...

This is where the exception is caught. $visibility will be null, then the exception thrown.

My disk setup is like yours: visibility set to private.

Downgrading to 3.15 does not resolve it for me though.

Did any of you guys find a solution for the problem? Move (and copy) seems not to be working on r2

[it-can]

this seems related: #1791

[it-can]

it seems the config is not passed down to the copy() function

$config = new Config([
    Config::OPTION_VISIBILITY => 'private',
]);

Storage::disk('r2')->move($orgFile, $archiveFile, $config);

when i debug this with ray(), i see the config object is not the same

So it seems the Laravel Disk/storage config is not passed correctly, so it tries to fetch the visibility from the file (GetObjectACL is not supported by Cloudflare R2), so it will throw an Exception.

It seems the the laravel disk config is not passed correctly to AwsS3V3Adapter.

UPDATE
when i manually comment out this part of the code:

try {
            $visibility = $config->get(Config::OPTION_VISIBILITY);

            if ($visibility === null && $config->get(Config::OPTION_RETAIN_VISIBILITY, true)) {
                $visibility = $this->visibility($source)->visibility();
            }
        } catch (Throwable $exception) {
            throw UnableToCopyFile::fromLocationTo(
                $source,
                $destination,
                $exception
            );
        }

and then add

$visibility = 'private';

the "moving/copying" of the file works...
