polysource/adapter-messenger

Polysource adapter exposing Symfony Messenger's failed transport as a read-only Polysource resource.

This is the cas tueur for v0.1: Symfony's Messenger has no built-in admin UI for inspecting failed messages — only the messenger:failed:* CLI. polysource/adapter-messenger plugs into the same failed transport and renders it inside /admin/failed-messages.

Installation

composer require polysource/adapter-messenger

The bundle auto-registers via Symfony Flex.

Configuration

# config/packages/polysource_messenger.yaml
polysource_messenger:
    failed_transport_name: failed   # default

The named transport must implement Symfony\Component\Messenger\Transport\Receiver\ListableReceiverInterface (Doctrine, Redis, AMQP, InMemory all do). The bundle throws a LogicException at boot if the transport is non-listable.

What the resource exposes

Property	Source
message_class	Envelope::getMessage()::class
failed_at	RedeliveryStamp::getRedeliveredAt() (UTC)
exception_class	ErrorDetailsStamp::getExceptionClass()
exception_message	ErrorDetailsStamp::getExceptionMessage()
payload	JSON-encoded message body, var_export fallback (ADR-006)
payload_format	'json' or 'var_export'

Records over 50 KB are truncated with a marker.

Status

v0.1 — read-only. Retry / dismiss / retry-all / purge actions ship in Phase 5 of the development plan.

Architectural decisions

• ADR-001 — identifier type
• ADR-002 — count = null for cursor sources
• ADR-006 — payload serialization
