NotionCommotion Posted July 26, 2021 Share Posted July 26, 2021 A while back, I was showed how to authenticate to PostgreSQL using peer authentication over a socket for applications where PHP, FPM, and PostgreSQL are all on the same machine. All works. I could use native PHP as shown and it returns results without errors so I know that PHP, FPM, and PostgreSQL is setup correctly to establish a connection using peer authentication without a PostgreSQL username or password. $pdo = new PDO("pgsql:dbname=testing"); $rs = $pdo->query('SELECT * FROM company')->fetchAll(); I could also use Doctrine but not Symfony and get results without errors so I know that Doctrine is capable of establishing a connection using peer authentication without a PostgreSQL username or password. $pdo = EntityManager::create(['driver' => 'pdo_pgsql','dbname' => 'testing'], Setup::createAnnotationMetadataConfiguration([__DIR__."/../src"], true, null, null, false))->getConnection(); $rs = $pdo->query('SELECT * FROM company')->fetchAll(); Now I am trying to do the same but when using Symfony. I expected I could just edit config/packages/doctrine.yaml as follows, however, it results in An exception occurred in driver: SQLSTATE[08006] [7] fe_sendauth: no password supplied doctrine: dbal: driver: pdo_pgsql dbname: testing server_version: 13 Any thoughts how to do this?

NotionCommotion Posted July 30, 2021 Author Share Posted July 30, 2021 Okay, I got it working but it seems like a hack. The following file creates a connection first without using Symfony and then with using Symfony. <?php use Doctrine\ORM\Tools\Setup; use Doctrine\ORM\EntityManager; use App\Kernel; use Symfony\Component\Dotenv\Dotenv; use Symfony\Component\ErrorHandler\Debug; use Doctrine\Common\Persistence\ObjectManager; use Doctrine\DBAL\Connection; ini_set('display_errors', 1); require dirname(__DIR__).'/vendor/autoload.php'; function getPdowithoutSymfony():Connection { $setup = Setup::createAnnotationMetadataConfiguration([__DIR__."/../src"], true, null, null, false); $em = EntityManager::create(['driver' => 'pdo_pgsql','dbname' => 'testing'], $setup); return $em->getConnection(); } function getPdowithSymfony():Connection { (new Dotenv())->bootEnv(dirname(__DIR__).'/.env'); if ($_SERVER['APP_DEBUG']) { umask(0000); Debug::enable(); } $kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']); $kernel->boot(); $em = $kernel->getContainer()->get('doctrine.orm.entity_manager'); return $em->getConnection(); } function test(Connection $pdo):int { $stmt = $pdo->executeQuery('SELECT COUNT(*) FROM public.user'); return $stmt->fetchColumn(); } echo('count without symfony: '.test(getPdowithoutSymfony()).PHP_EOL); echo('count with symfony: '.test(getPdowithSymfony()).PHP_EOL); Then in the following class I added the echo and var_dump lines: <?php namespace Doctrine\DBAL\Driver; class PDOConnection extends PDO implements ConnectionInterface, ServerInfoAwareConnection { public function __construct($dsn, $user = null, $password = null, ?array $options = null) { try { echo(get_class($this).PHP_EOL); var_dump(['$dsn'=>$dsn, '$user'=>$user, '$password'=>$password, '$options'=>$options, ]); parent::__construct($dsn, (string) $user, (string) $password, (array) $options); $this->setAttribute(PDO::ATTR_STATEMENT_CLASS, [Statement::class, []]); $this->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $exception) { throw Exception::new($exception); } } } If I configure Symfony to use doctrine.dbal as {driver: pdo_pgsql,dbname: testing, server_version: 13}, I get: \Doctrine\DBAL\Driver\__construct Doctrine\DBAL\Driver\PDO\Connection array(4) { ["$dsn"]=> string(21) "pgsql:dbname=testing;" ["$user"]=> NULL ["$password"]=> NULL ["$options"]=> array(0) { } } count without symfony: 10 Doctrine\DBAL\Driver\PDO\Connection array(4) { ["$dsn"]=> string(36) "pgsql:host=localhost;dbname=testing;" ["$user"]=> string(4) "root" ["$password"]=> NULL ["$options"]=> array(0) { } } <!-- An exception occurred in driver: SQLSTATE[08006] [7] fe_sendauth: no password supplied (500 Internal Server Error) --> So, then I configured Symfony to use doctrine.dbal as {driver: pdo_pgsql,dbname: testing, server_version: 13, user: null, host: null}, and no errors. Doctrine\DBAL\Driver\PDO\Connection array(4) { ["$dsn"]=> string(21) "pgsql:dbname=testing;" ["$user"]=> NULL ["$password"]=> NULL ["$options"]=> array(0) { } } count without symfony: 10 Doctrine\DBAL\Driver\PDO\Connection array(4) { ["$dsn"]=> string(21) "pgsql:dbname=testing;" ["$user"]=> NULL ["$password"]=> NULL ["$options"]=> array(0) { } } count with symfony: 10 Zero documentation describing this as far as I could tell. Anyone know whether there is a more proper way to do this? Quote Link to comment Share on other sites More sharing options...
