[Doctrine Bridge] Added parameter ignoreNull to accept a nullable value on field
In my last project, i use this syntax to test unicity on 2 fields, but it fail because the validator stop if value is null. I dropped the test on validator and my unicity work fine.
```
@UniqueEntity(fields={"username", "deletedAt"})
```
It's possible to add this PR on Bridge.
Thanks

This is wrong. RDBMS allow several null values in a unique column and this change will break it.
---------------------------------------------------------------------------

@stof seems weird indeed it would return if any of the values are null. Makes sense to do a query where the field `IS NULL` or whatever the find method does.
---------------------------------------------------------------------------
by stof at 2012-07-23T08:18:50Z
@henrikbjorn if you do a query with IS NULL, the validator would force to have only 1 entity with a null field whereas it is not the behavior of the DB-level constraint.
---------------------------------------------------------------------------
by henrikbjorn at 2012-07-23T08:20:41Z
In this case i suspect that he wants to achieve a `WHERE username = "henrikbjorn" AND deletedAt IS NULL` which would be valid right? Currently it just returns if any of the fields are null and the validation is never done.
---------------------------------------------------------------------------

I suggest to make this configurable as the handling of NULL values in UNIQUE columns [differs between SQL implementations](http://forums.mysql.com/read.php?22,53591,53591#msg-53591).
---------------------------------------------------------------------------
by Garfield-fr at 2012-07-23T08:52:53Z
@stof What the correct solution to test my unicity with deletedAt == null ?
I use this definition: @ORM\Column(name="deleted_at", type="datetime", nullable=true)
---------------------------------------------------------------------------

In my local repository, i added a new parameter "$authorizedNullField" on UniqueEntity.php and tested this on UniqueEntityValidator.php:

what about ``allowMultipleNull`` (defaulting to ``true`` for BC) ?

Why multiple ? This option is for one or many. what about `allowNullable` ?
---------------------------------------------------------------------------
by stof at 2012-07-23T20:52:44Z
@Garfield-fr the current behavior allows having multiple null values without failing to the unique constraint
---------------------------------------------------------------------------
by Garfield-fr at 2012-07-23T20:56:07Z
ok. I make `allowMultipleNull`.
It's ok with that: https://gist.github.com/cae8d43780c45a5011ed
Thanks
---------------------------------------------------------------------------
by bschussek at 2012-07-23T20:58:12Z
What about `uniqueNull` (`false` by default)? `ignoreNull` (`true` by default)? I find `allowMultipleNull` a bit cumbersome.
---------------------------------------------------------------------------
by stof at 2012-07-23T20:58:26Z
no it is not. You have an issue in the validator. You have an extra negation.
Please update your PR

[Form] Fixed variable passing from outer to inner blocks of the same FormView instance
Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: #5029
Todo: -
This PR fixes two bugs.
The first bug is described in #5029. The second parameter to the "form_label" function in Twig, if given, always overwrote whatever label was defined previously.
```
{# null would overwrite whatever is currently set #}
form_label(form, null, { ... })
```
The second bug affected passing variables from outer to inner blocks. In the following example, "label_attr" would not be forwarded to the "form_label" function.
```
form_row(form, { "label_attr": { "class": "my_class" }})
```
Both bugs are fixed now.

[Form] Made FormView and ChoiceView properties public for performance reasons
Bug fix: no
Feature addition: no
Backwards compatibility break: **yes**
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: -
This PR changes the access to properties of `FormView` and `ChoiceView` objects from getters to direct property accesses. On [my example form](http://advancedform.gpserver.dk/app_dev.php/taxclasses/1) this improves rendering performance for **300ms** with PHP templates and **550ms** with Twig on my local machine.
Unfortunately, this breaks BC both with 2.0 and with the current master in Form Types and PHP templates. Twig templates are not affected by this change.
2.0:
```
$formView->set('my_var', 'foobar');
$formView->get('my_var');
$formView->getChild('childName');
$formView['childName'];
```
master:
```
$formView->setVar('my_var', 'foobar');
$formView->getVar('my_var');
$formView->get('childName');
$formView['childName'];
```
this PR:
```
$formView->vars['my_var'] = 'foobar';
$formView->vars['my_var'];
$formView->children['childName'];
$formView['childName'];
```
Should we add methods to keep BC with 2.0?
The second part of this PR contains improvements to the rendering of choice fields. These gain another **~500ms** for PHP templates and **80ms** for Twig. These improvements are BC, unless you overwrote the block "choice_widget_options" in your form themes which then needs to be adapted.
**Update:**
The PR now includes a BC layer for 2.0.
---------------------------------------------------------------------------
by stof at 2012-07-21T11:37:41Z
@bschussek couldn't we keep the getters and setters for BC even if the rendering accesses the public properties directly ?
---------------------------------------------------------------------------
by bschussek at 2012-07-21T11:52:33Z
@stof A BC layer for 2.0 is now included. People who upgraded to master already unfortunately need to adapt their code.

[Form] Merged FormHelper and FormExtension and implemented a better caching strategy
Bug fix: no
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: -
This PR extracts common parts of `FormHelper` and `FormExtension` into implementations of the new interfaces `FormRendererInterface` and `FormRendererEngineInterface`. The implemented `AbstractRendererEngine` features a more intelligent caching strategy than the one used before. When this strategy was implemented directly in `FormHelper`, the performance of [this specific, heavy form](http://advancedform.gpserver.dk/app_dev.php/taxclasses/1) could be improved from **2.5** to **2.25 seconds** on my machine for PHP templates.
Due to the abstraction and delegation, the performance gain is not that big anymore, but we still have a performance gain of about **0.1 seconds** for both PHP and Twig in the above example. The second, big improvement of this PR is maintainability - the differences between PHP and Twig templates are now contained in relatively small classes - and extendability (it is very easy now to support different template engines).
---------------------------------------------------------------------------
by stof at 2012-07-14T13:47:19Z
should a similar refactoring be done for the [Twig rendering](https://github.com/symfony/symfony/blob/master/src/Symfony/Bridge/Twig/Extension/FormExtension.php) ?
---------------------------------------------------------------------------
by bschussek at 2012-07-14T13:49:25Z
Yes. I would like to merge the common parts of Twig's FormExtension and PHP's FormHelper into an abstract class. Before that I need to have a [working, heavy Twig Form](https://twitter.com/webmozart/status/224135287377371138) in order to measure whether I don't actually decrease the performance with Twig. Can you help me there?

Would it make sense to create a 'renderer' folder in the form component and move related classes there ?
---------------------------------------------------------------------------
by stof at 2012-07-16T22:06:58Z
@vicb It makes sense to keep the Twig renderer in the brisge. This is what the bridge is about. Moving the Twig class to the component would not be consistent. And the PHP renderer is already in the component (but it could make sense to move the helper from FrameworkBundle to the TemplatingExtension of the Form component though)
---------------------------------------------------------------------------
by vicb at 2012-07-16T22:16:50Z
@stof I was only referring to the classes located in the Component/Form folder.
---------------------------------------------------------------------------
by vicb at 2012-07-16T22:27:27Z
Overall I don't really know what to think of this PR. PHP and Twig use a different way to support blocks:
- PHP has one block per file,
- Twig could have many blocks per templates.
I am not sure if this PR is optimal for Twig and improves maintainability ?
---------------------------------------------------------------------------
by stof at 2012-07-16T22:46:11Z
@vicb it avoids duplicating the whole rendering logic for each engine (there is at least a third one in [SmartyBundle](https://github.com/noiselabs/SmartyBundle/blob/master/Extension/FormExtension.php) btw)
---------------------------------------------------------------------------
by bschussek at 2012-07-17T07:16:42Z
@vicb I don't think a renderer subfolder makes sense. The interfaces belong to the main namespace, and then the subfolder would only contain two classes.
Considering maintainability for Twig, I think that this PR in fact increases it. TwigExtension before always had to check the whole type hierarchy, while now the code in AbstractRendererEngine makes sure that this process is speeded up.
Before:
```
load _some_entity_field_label:
- check _some_entity_field_label
- check entity_label
- check choice_label
- check form_label
load _some_other_entity_field_label
- check _some_other_entity_field_label
- check entity_label
- check choice_label
- check form_label
a.s.o.
```
After:
```
load _some_entity_field_label:
- check _some_entity_field_label
- check entity_label (hits the cache if entity_label was checked before)
- check choice_label (hits the cache if choice_label was checked before)
- check form_label
load _some_other_entity_field_label
- check _some_other_entity_field_label
- check entity_label (now definitely hits the cache)
a.s.o.
```
Since many fields share the same ancestors in the inheritance tree, this definitely improves performance.
As can also be deducted here, custom block names such as `_some_entity_field_label` are now a major drawback. There is nothing we can cache for them, so they need to be checked for every individual block that we load. Removing this feature surprisingly gains no performance for Twig (I need to investigate why at some point), but it speeds up rendering for **250ms** using the PHP engine on [this example form](advancedform.gpserver.dk/app_dev.php/taxclasses/1), dropping the rendering time from 1.25 to 1 sec on my local machine. I'm not sure what we should do here.
---------------------------------------------------------------------------
by stof at 2012-07-17T07:21:31Z
@bschussek could it be possible to have an implementation checking the custom block and another one skipping it ? This way, the user could disable this feature when he does not need it.
---------------------------------------------------------------------------
by bschussek at 2012-07-17T07:38:34Z
@stof It would be possible to add a switch to `FormRenderer` that controls whether custom blocks are checked or not.
If this switch is disabled by default, we break BC. If this switch is enabled by default, it will be pretty useless. People will start designing away for custom blocks, and once they want to improve performance, they can't turn off the switch anymore because it would require too many changes.
---------------------------------------------------------------------------
by stof at 2012-07-17T08:08:38Z
@fabpot what do you think about it ?
---------------------------------------------------------------------------
by bschussek at 2012-07-17T08:41:43Z
Another option that just came to mind is to remove inheritance checks for anything but _widget and _row. I.e., if we render `entity_widget`, check
```
_id_widget
entity_widget
choice_widget
form_widget
```
But if we render `entity_label`, only check
```
_id_label
form_label
```
This improves PHP Templating for **170ms** and Twig for **20ms**. We gain another **150ms** for PHP Templating and **~15ms** for Twig if we also restrict custom fields (_id_widget) to the _widget and _row suffixes (it's really hard to tweak the renderer for Twig.. I think a lot of its performance bottlenecks lie in Twig itself).
Do you have any data on how often blocks other than _widget and _row are customized for specific types/IDs?
---------------------------------------------------------------------------
by stof at 2012-07-17T09:47:38Z
Well, I think most of the time other blocks are not even customized based on the type :)
---------------------------------------------------------------------------
by Tobion at 2012-07-17T14:32:39Z
From my experience rendering the form components individually is easier and more flexible than customizing by ID or type.
But there are still use cases for customizing like library-like bundles (e.g. Bootstrap).

[Form] WIP Improved performance of form building
Bug fix: no
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: **Update the Silex extension**
This PR is work in progress and up for discussion. It increases the performance of FormFactory::createForm() on a specific, heavy-weight form from **0.848** to **0.580** seconds.
Before, the FormFactory had to traverse the hierarchy and calculate the default options of each FormType everytime a form was created of that type.
Now, FormTypes are wrapped within instances of a new class `ResolvedFormType`, which caches the parent type, the type's extensions and its default options.
The updated responsibilities: `FormFactory` is a registry and proxy for `ResolvedFormType` objects, `FormType` specifies how a form can be built on a specific layer of the type hierarchy (e.g. "form", or "date", etc.) and `ResolvedFormType` *does the actual building* across all layers of the hierarchy (by delegating to the parent type, which delegates to its parent type etc.).

This looks good to me
By default, the UniqueEntityValidator maps the violation on the first
field of the UniqueEntity constraint. The new option allows to control
this behavior if a better mapping is suited.
