Description

As part of #50852 the return types for both methods in Symfony\Component\Lock\LockFactory were narrowed from the base LockInterface to the SharedLockInterface. In some test cases, we are mocking the lock factory and the mock provides a NoLock instance to disable locks in the context of those tests. Since NoLock does not implement SharedLockInterface, using it with the LockFactory is no longer possible.

How to reproduce

$lockFactory = $this->createMock(LockFactory::class);
$lockFactory->method('createLock')
    ->willReturnCallback(static fn () => new NoLock());
// Test fails with:
// TypeError : Mock_LockFactory_a4c266f2::createLock(): Return value must be of type Symfony\Component\Lock\SharedLockInterface, Symfony\Component\Lock\NoLock returned

Possible Solution

One of:

• Restore the return type of the LockFactory methods to the base LockInterface
• Implement SharedLockInterface in the NoLock class
