Original Pull Request: https://github.com/doctrine/orm/pull/949

State: closed
Merged: No

Following this discussion on the mailing list, this proposal introduces a default lock mode for all entities loaded through an EntityManager.

At the moment, there is no way to set a lock mode for the following use cases:

Proxies obtained through getReference() and then initialized
Entities lazy-loaded through traversal of associations

This proposal introduces the idea of a default lock mode, which can be set at runtime when all reads in a transaction should be locking.

It works this way:

$transaction = $em->createTransaction()
    ->withDefaultLockMode(LockMode::PESSIMISTIC_WRITE)
    ->begin();

// load entities from EntityManager, Repositories or DQL, traverse associations, etc.
// all these entities will be loaded with the given lock mode

$transaction->commit();

I have successfully tested it with the following use cases:

EntityManager::find()
EntityRepository::findBy()
DQL queries
Proxies
Lazy-loaded collections through OneToMany and ManyToMany associations

Happily waiting for your feedback!
