Handle Doctrine transactions (ORM 3 wrapInTransaction), optimistic/pessimistic locking, flush strategies, and transaction boundaries.
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
# Doctrine Transactions (Symfony) ## Use when - Several writes must succeed or fail together. - Two users or workers can edit the same row concurrently. - Deciding where to flush and who owns the transaction boundary. - Recovering after a failed flush, a constraint violation, or a lost connection. ## Default workflow 1. Place the transaction boundary in the service layer, not in the controller. 2. Group related changes and flush once, inside `wrapInTransaction()`. 3. Pick the concurrency strategy: `#[ORM\Version]` optimistic locking for edits, `PESSIMISTIC_WRITE` for short critical sections. 4. Handle `OptimisticLockException` and constraint violations explicitly. 5. After a rollback, clear the EntityManager and re-fetch what you still need. ## Guardrails - On ORM 3, `EntityManager::transactional()` is gone: use `wrapInTransaction()`. - Outside an explicit transaction each flush commits on its own, so avoid several flushes per operation. - Keep transactions and pessimistic locks short; no HTTP calls or mail inside. - Do not reuse entities from a failed unit of work. ## Progressive disclosure - Use this file for execution posture and risk controls. …

How to install
mdr add dev-toolings/superpowers-symfony/doctrine-transactions@sha256:3b6dddf10a101630The line at the top of this page pins the label git:20261005.6632a97, 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.
