Flysystem Stream Wrapper

---

This package provides a stream wrapper for Flysystem V2 & V3.

Flysystem V1

If you're looking for Flysystem 1.x support, check out the twistor/flysystem-stream-wrapper.

Installation

composer require m2mtech/flysystem-stream-wrapper

Usage

use League\Flysystem\Filesystem;
use League\Flysystem\Local\LocalFilesystemAdapter;
use M2MTech\FlysystemStreamWrapper\FlysystemStreamWrapper;

$filesystem = new Filesystem(new LocalFilesystemAdapter('/some/path'));
FlysystemStreamWrapper::register('fly', $filesystem);

file_put_contents('fly://filename.txt', $content);
mkdir('fly://happy_thoughts');

FlysystemStreamWrapper::unregister('fly');

The stream wrapper implements symfony/lock due to Flysystem V2 not supporting locking. By default, file locking using /tmp is used, but you can adjust this through configuration:

FlysystemStreamWrapper::register('fly', $filesystem, [
    FlysystemStreamWrapper::LOCK_STORE => 'flock:///tmp',
    FlysystemStreamWrapper::LOCK_TTL => 300,
]);

Handling Visibility Issues

Some adaptors might throw exceptions when dealing with visibility. If you encounter such issues, configure the stream wrapper to bypass them:

FlysystemStreamWrapper::register('fly', $filesystem, [
    FlysystemStreamWrapper::IGNORE_VISIBILITY_ERRORS => true,
]);

Addressing Directory Issues (file_exists / is_dir)

Some adaptors might not return dates for the last modified attribute for directories. In such cases, you can enable emulation to achieve the desired behavior:

FlysystemStreamWrapper::register('fly', $filesystem, [
    FlysystemStreamWrapper::EMULATE_DIRECTORY_LAST_MODIFIED => true,
]);

Dealing with is_readable / is_writable

Some filesystem functions depend on the uid and gid of the user executing PHP. Since a reliable cross-platform method to derive these values isn't available, the wrapper attempts to estimate them. If this fails, set them manually:

FlysystemStreamWrapper::register('fly', $filesystem, [
    FlysystemStreamWrapper::UID => 1000,
    FlysystemStreamWrapper::GID => 1000,
]);

Alternatively, access the parameters for PortableVisibilityConverter directly:

FlysystemStreamWrapper::register('fly', $filesystem, [
    FlysystemStreamWrapper::VISIBILITY_FILE_PUBLIC => 0644,
    FlysystemStreamWrapper::VISIBILITY_FILE_PRIVATE => 0600,
    FlysystemStreamWrapper::VISIBILITY_DIRECTORY_PUBLIC => 0755,
    FlysystemStreamWrapper::VISIBILITY_DIRECTORY_PRIVATE => 0700,
    FlysystemStreamWrapper::VISIBILITY_DEFAULT_FOR_DIRECTORIES => Visibility::PRIVATE,
]);

Testing

This package was developed using PHP 7.4 and has been tested for compatibility with PHP versions 7.2 through 8.3.

To test:

• With PHP installed:

composer test

• Inside a Docker environment for PHP 7.4:

docker compose run php74 composer test

Note: PHPUnit v10, used from PHP 8.1 onwards, requires a different config file:

docker compose run php81 composer test10
