==========================

[](#octo-phpsymfony-messenger)

Transport Symfony Messenger in-process pour la plateforme async PHP — message passing via channels OpenSwoole bornés avec backpressure.

Installation
------------

[](#installation)

```
composer require octo-php/symfony-messenger
```

Configuration
-------------

[](#configuration)

### DSN

[](#dsn)

```
# config/packages/messenger.yaml
framework:
    messenger:
        transports:
            async:
                dsn: 'openswoole://default'
                options:
                    channel_capacity: 100
                    send_timeout: 5.0
```

octo:
    messenger:
        channel_capacity: 100
        consumers: 1
        send_timeout: 5.0
```

Fonctionnement
--------------

[](#fonctionnement)

Le transport utilise un channel OpenSwoole borné pour le message passing in-process :

- `send()` : push le message dans le channel. Si le channel est plein, la coroutine yield (backpressure) jusqu'à ce qu'un espace soit disponible ou que le timeout soit atteint.
- `get()` : pop un message du channel avec un poll timeout de 1s.
- `ack()` : no-op (in-process, pas de broker externe).
- `reject()` : log warning.

Les consumers sont spawnés au boot du worker via structured concurrency (`TaskGroup`) et annulés proprement au shutdown (pas de coroutines zombies).

-----------

[](#limitations)

### Transport in-process uniquement

[](#transport-in-process-uniquement)

Ce transport est **non distribué** et **non durable** :

- Les messages sont stockés en mémoire dans le channel OpenSwoole du worker
- Le channel est **isolé par worker** : les messages ne sont pas partagés entre workers
- Les messages **non consommés au moment du restart du worker sont perdus**

### Cas d'usage adaptés

[](#cas-dusage-adaptés)

- Fire-and-forget (notifications, logs asynchrones)
- Background jobs légers (envoi d'emails, cache warming)
- Traitement asynchrone intra-requête

### Cas d'usage non adaptés

[](#cas-dusage-non-adaptés)

Pour le messaging durable, distribué ou critique, utiliser les transports externes standard Symfony :

- AMQP (RabbitMQ)
- Redis
- Doctrine

Retry et failure transport
--------------------------

[](#retry-et-failure-transport)

Les mécanismes standard de retry et failure transport de Symfony Messenger s'appliquent normalement :

```
framework:
    messenger:
        transports:
            async:
                dsn: 'openswoole://default'
                retry_strategy:
                    max_retries: 3
                    delay: 1000
                    multiplier: 2

        failure_transport: failed

        transports:
            failed:
                dsn: 'doctrine://default?queue_name=failed'
```

Pour les messages critiques, configurez un failure transport durable (Doctrine, Redis) afin de ne pas perdre les messages en cas de restart.
