Doctrine 2 Doctrine\ORM\Persisters\Entity\BasicEntityPersister::getSelectSQL() method issue

[kbora504]

There seems to be a bug in method
public function getSelectSQL($criteria, $assoc = null, $lockMode = null, $limit = null, $offset = null, array $orderBy = null)
As per documentation of Doctrine\ORM\Persisters\Entity\EntityPersister the $criteria parameter should be of type array; so, the below code

$conditionSql = ($criteria instanceof Criteria)
            ? $this->getSelectConditionCriteriaSQL($criteria)
            : $this->getSelectConditionSQL($criteria, $assoc);

will never execute $this->getSelectConditionCriteriaSQL($criteria) statement, because it is always of type array. Please fix this, so that it accepts single criteria object too.

@kbora504 could you please write a failing test case that demonstrates the issue?

[kbora504]

It is very obvious from code written. Just check the passed parameter type is array and we are checking for instanceof Criteria.

[Ocramius]

It doesn't really matter from our perspective: tests verify the behavior and prevent regressions. No tests = no fix/merge ;-)

[kbora504]

@Ocramius I understand your point. But how can I write test case for a satement inside function?
:(

[Ocramius]

@kbora504 you got a stack trace there: how did you get to that failure? Can you isolate it and make an example that reproduces the problem? See https://github.com/doctrine/doctrine2/tree/388afb46d0cb3ed0c51332e8df0de9e942c2690b/tests/Doctrine/Tests/ORM/Functional/Ticket for examples
