 Description   

The following DQL query is working fine on 2.4 but breaks on 2.5:

SELECT COUNT(l) FROM Incenteev\WebBundle\Entity\Discussion\Liker l INNER JOIN l.message m INNER JOIN m.thread t WHERE t.space IN (:space_ids) AND l.date >= :from

This is the exception triggered in 2.5:

[Semantical Error] line 0, col 13 near 'l) FROM Incenteev\WebBundle\Entity\Discussion\Liker': Error: Invalid PathExpression. Must be a StateFieldPathExpression. 

The exception happens in Parser->processDeferredPathExpressions.

The Liker class has a compound identifier based on 2 relations.

I suspect it is related to https://github.com/doctrine/doctrine2/pull/1122

I'm not sure it is a BC break though. Looking at the SQL generated in 2.4, it was not counting the right thing (is was counting only the message ids, not the combination message id/user id being the primary key.

Comment by Christophe Coevoet [ 28/May/15 ]

Actually, it was counting the right thing when not using DISTINCT (the 2.4 generated SQL was broken for DISTINCT though)

Comment by Guilherme Blanco [ 28/May/15 ]

Yep, that PR was the culript. I can look into this issue later.

We currently have a lot of locations in the code where we use list($values, $types) = $this->computeParameters(); (pseudo-code).

This leads to a lot of code duplication and complexity.

Maybe a Parameter VO may be used instead, or a ParameterCollection with a fixed $types and a mutable $values, and with minimal internal validation.





[DDC-3512] Redesign ClassMetadata API as ValueObject based (for type-safety and self-documentation) Created: 17/Jan/15  Updated: 18/Jan/15

relates to DDC-3503 [GH-1257] Resolve target entity also ... Resolved

 Description   

The current ClassMetadata API is based on a lot of array juggling (for performance reasons).

While that was understandable with PHP 5.3, all the array access operations are currently:

  • slowing things down
  • making the code very hard to read/understand

I suggest re-coding the ClassMetadata internals (public properties and such) so that well-described properties are defined.

Additionally, as a bonus, we'd get a performance boost by just moving all the class-alias and type resolution logic from the runtime into the ClassMetadataFactory (or similar) API, saving tons of performance at every run.

In pseudo-logic, what I'd like to achieve with DDC-3512 is:

  • base metadata is loaded from the mapping driver
  • onLoadMetadata event is fired for each loaded metadata instance
  • metadata is completed by the ClassMetadataFactory logic
  • onCompleteMetadata event is fired for each loaded metadata instance

This would make metadata manipulation from events a bit messier (user needs to know which value to change during which event), but would allow using better constrained metadata structures in future, and that would disallow mistakes during event listeners execution as well (internal validation).

 Description   

The Unidirectional ManyToOne association described in the docs does not lazy load correctly. The appropriate SQL will get executed, and the returned Proxy does pass type hinting for the correct class. However, the lazy loaded object always has the following properties:

  • _initializer_
  • _cloner_
  • _isInitialized_
  • lazyPropertiesDefaults

Any properties from the class definition do not show up. This is problematic when trying to get reflected properties and their values. Methods are correctly reflected.

Looks like a current ORM limitation (private properties lazy loading).

 Description   

Hi Benjamin

Problem custom name sequeceGenerator YAML why not create the custom name you want. Being created the default postgres, where is the problem?

Note: https://groups.google.com/forum/#!topic/doctrine-user/7ctTFGWu4mo

Message:

  type: entity
  id:
    id:
      type: integer
      generator:
        strategy: SEQUENCE
      sequenceGenerator:
        sequenceName: message_sq
        allocationSize: 100
        initialValue: 1

The entity is created like this:

namespace message\models\entities;

use Doctrine\ORM\Mapping as ORM;

/**
 * Message
 *
 * @ORM\Table(name="message")
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 */
class Message
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="SEQUENCE")
     * @ORM\SequenceGenerator(sequenceName="message_id_seq", allocationSize=1, initialValue=1)
     */

Should be created as specify:

/**
 * Message
 *
 * @ORM\Table(name="message")
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 */
class Message
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="SEQUENCE")
     * @ORM\SequenceGenerator(sequenceName="message_sq", allocationSize=1, initialValue=1)

Is the bug reproducible also in 2.4.6?

Comment by Steve Müller [ 22/Oct/14 ]

Moved to ORM issue tracker. This is not DBAL related.

Hi

Is the bug reproducible also in 2.4.6 and 2.5.0-DEV





[DDC-3212] Remove ArrayHydrator logic Created: 14/Jul/14  Updated: 13/Oct/14

Status: Open
Project: Doctrine 2 - ORM

 Description   

The Doctrine\ORM\Internal\Hydration\ArrayHydrator ( https://github.com/doctrine/doctrine2/blob/85fbf684363b932a4ebaf543ef059f9ee1e512b0/lib/Doctrine/ORM/Internal/Hydration/ArrayHydrator.php ) is currently very messy and complicated due to the lack of actual Doctrine\ORM\UnitOfWork references when working with it, since we are not dealing with objects.

In order to reduce the amount of bugs and code duplication when working with array hydration, I would simply suggest making use of the Doctrine\ORM\Internal\Hydration\ObjectHydrator ( https://github.com/doctrine/doctrine2/blob/85fbf684363b932a4ebaf543ef059f9ee1e512b0/lib/Doctrine/ORM/Internal/Hydration/ObjectHydrator.php ) and its siblings, and then extracting data coming from the results in it as an array.

This could be a simple reflection-based extraction (pseudo):

class ArrayHydrator
{
    public function hydrateAllData()
    {
        foreach ($this->objectHydrator->hydrateAllData() as $object) {
            yield $this->extractData($object);
        }
    }
}

The point here is that array-based hydration is not the primary focus of the ORM, and users should probably rely on SQL only when they want array hydration.

Note: performance is one of our biggest requirements, and array hydration is meant to achieve that. As I stated above, plain SQL is probably better for this sort of operation, so the issue is more about deprecating the ArrayHydrator completely, providing utilities to manipulate SQL resultsets instead.

 Description   

I will explain the problem using example and pseudo-code:

I have query like that:
SELECT (...) FROM order LEFT JOIN person LEFT JOIN identifier (...) order by (...)

The rows returned by query are following (the order is very important):
order_id|person_id|identifier_id|
12 |21 |33 |
12 |21 |34 |
11 |21 |35 |
11 |21 |33 |
11 |21 |34 |
12 |21 |35 |

After hydration the result is like:
result[0][person][identifier][0][id]=33
result[0][person][identifier][0][id]=34
result[1][person][identifier][0][id]=35
result[1][person][identifier][0][id]=34

But it should be:
result[0][person][identifier][0][id]=33
result[0][person][identifier][0][id]=34
result[0][person][identifier][0][id]=35
result[1][person][identifier][0][id]=35
result[1][person][identifier][0][id]=34
result[1][person][identifier][0][id]=33

The reason is that ArrayHydrator::_identifierMap contains only object id and parents object id. In may example there is difference in parents parent (grandparent) id.

This is how I temporary solved the issue, maybe it can help (attachment).

Comment by Marco Pivetta [ 06/Feb/14 ]

Mariusz Jaskółka can you provide a diff with current master? This seems to be based off 2.3 or previous versions...

Version 2.4.2 oryginal file and bugfix

Comment by Mariusz Jaskółka [ 06/Feb/14 ]

Oh sorry it is version 2.4.1 (composer downloaded that version for me).
I hope it will be ok.

Comment by Marco Pivetta [ 06/Feb/14 ]

Mariusz Jaskółka thanks! I'm trying it right now

Comment by Mariusz Jaskółka [ 06/Feb/14 ]

I added one dimention to $this->_identifierMap to be sure that all object's children's keys will be mapped separately.

Comment by Marco Pivetta [ 06/Feb/14 ]

Mariusz Jaskółka, I've applied your hotfix at https://github.com/doctrine/doctrine2/commit/c05921032ff6947daca2d7275031e5cde4700634 and the tests seem to pass on my system and on travis. You may want to check it out and see if it works for your use case.

Comment by Mariusz Jaskółka [ 06/Feb/14 ]

It works for my use case correctly. You apparently forgot to remove/comment line 82 which is not necessary now.

Comment by Marco Pivetta [ 06/Feb/14 ]

Mariusz Jaskółka fixed, thanks!

Comment by Marco Pivetta [ 14/Jul/14 ]

I don't think we'll have a fix for this issue for 2.5, as it will probably require a complete rewrite of the array hydrator
