[Messenger] Cannot force configuration to read multiplier from env #62370
Description
Symfony version(s) affected
6.4.28,7.3.6
Description
Today I wanted to set two new environment variables:
MESSENGER_MAX_RETRIES=3
MESSENGER_MULTIPLIER=2Unfortunately I am not able to set multiplier in my async transport to use the second value.
I am getting error:
In NumericNode.php line 45:
The value 0 is too small for path "framework.messenger.transports.async.retry_strategy.multiplier". Should be greater than or equal to 1
So the problem is that value is set to zero, although I set it as positive number e.g. 2.
How to reproduce
- Configure
.env
MESSENGER_MAX_RETRIES=3
MESSENGER_MULTIPLIER=2- Configure
config/services.yaml
messenger_multiplier: 5
# messenger_multiplier: '%env(float:MESSENGER_MULTIPLIER)%'- Configure async transport in
config/packages/messenger.yaml
framework:
messenger:
transports:
# https://symfony.com/doc/current/messenger.html#transport-configuration
async:
dsn: '%env(MESSENGER_TRANSPORT_DSN)%'
# default configuration
retry_strategy:
max_retries: '%env(int:MESSENGER_MAX_RETRIES)%'
# milliseconds delay
delay: 1000
# causes the delay to be higher before each retry
# e.g. 1 second delay, 2 seconds, 4 seconds
multiplier: '%messenger_multiplier%'
max_delay: 0
# override all of this with a service that
# implements Symfony\Component\Messenger\Retry\RetryStrategyInterface
# service: null
failure_transport: failed_default
# failed: 'doctrine://default?queue_name=failed'
sync: 'sync://'
failed_default:
dsn: '%env(MESSENGER_FAILED_DSN)%'
failure_transport: failed_default
routing:
# Route your messages to the transports
'App\Message\SmsNotification': async- Add message maker command
src/Command/SendSmsCommand.php
<?php
declare(strict_types=1);
namespace App\Command;
use App\Message\SmsNotification;
use Symfony\Component\Console\Attribute\AsCommand;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Messenger\MessageBusInterface;
#[AsCommand(name: 'app:send-sms', description: 'Hello PhpStorm')]
class SendSmsCommand extends Command
{
public function __construct(
private MessageBusInterface $messageBus,
) {
parent::__construct();
}
protected function execute(InputInterface $input, OutputInterface $output): int
{
$message = new SmsNotification('Hello PhpStorm!');
$this->messageBus->dispatch($message);
return Command::SUCCESS;
}
}- Add some message class
src/Message/SmsNotification.php
<?php
declare(strict_types=1);
namespace App\Message;
class SmsNotification
{
public function __construct(
private string $content,
) {
}
public function getContent(): string
{
return $this->content;
}
}- And its handler
src/MessageHandler/SmsNotificationHandler.php:
<?php
declare(strict_types=1);
namespace App\MessageHandler;
use App\Message\SmsNotification;
use Symfony\Component\Messenger\Attribute\AsMessageHandler;
#[AsMessageHandler]
class SmsNotificationHandler
{
public function __invoke(SmsNotification $message)
{
throw new \RuntimeException('This is a demo message handler.');
echo 'Processing: ' . $message->getContent(), PHP_EOL;
}
}Possible Solution
I cannot say what causes the problem.
I wrote some additional code to check if I can inject both environment variables into some constructor and the only thing that is not working is Symfony Messenger.
I don't know if it is my mistake or there is some bug.
Additional Context
I was trying to set multiplier in few ways:
- by
'%env(float:MESSENGER_MULTIPLIER)%'- not working - by fixed value e.g.
3- works fine - by using
'%messenger_multiplier%'- works fine only ifmessenger_multiplieris set to fixed value e.g.3
