Schedule recurring tasks with the Symfony Scheduler component (native since 7.x); define schedules, triggers, and integrate with Messenger.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Symfony Scheduler (Symfony)
## Use when
- Running recurring work (reports, cleanups, syncs) without system cron entries.
- Choosing between `RecurringMessage::every()`, `RecurringMessage::cron()`, and a custom `TriggerInterface`.
- Splitting jobs into several named schedules with `#[AsSchedule]`.
- Preventing overlap or lost runs of heavy scheduled tasks.
## Default workflow
1. Install `symfony/scheduler`, then write the message and its `#[AsMessageHandler]` handler.
2. Create a `#[AsSchedule('default')]` class implementing `ScheduleProviderInterface` and add `RecurringMessage` entries.
3. Pick the trigger: `every('5 minutes')` or `cron('0 */6 * * *')`, with an explicit timezone for cron.
4. Add `stateful($cache)` and `lock($lockFactory->createLock('scheduler'))` on the `Schedule` for heavy tasks.
5. Run it with `messenger:consume scheduler_default` under Supervisor, one process per schedule.
6. Log with `PreRunEvent` and `PostRunEvent`, and test the provider through `getRecurringMessages()` and `getNextRunDate()`.
## Guardrails
- Run a single consumer per schedule (`numprocs=1`) and add a lock, or the same task fires twice.

How to install
mdr add dev-toolings/superpowers-symfony/symfony-scheduler@sha256:e639576c705c7998The line at the top of this page pins the label git:20261005.51f9253, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
