handle inheritance in config:dump-reference when a bundle name is passed to the command
Added Yaml\Dumper::setIndentation() method to allow a custom indentation level of nested nodes.

YAML does not specify an absolute indentation level, but a consistent indentation of nested nodes only: http://www.yaml.org/spec/1.2/spec.html#space/indentation/

Projects that are generally using 2 spaces for indentation should be able to retain consistency with their coding standards by supplying a custom value for the new $indent parameter added to Yaml::dump(), or the new Dumper::setIndentation() method.

The new parameter is a backwards-compatible API addition and defaults to the previous default of 4 (which was changed from 2 via PR #2242 only recently).

[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.

---------------------------------------------------------------------------

by henrikbjorn at 2012-07-23T08:17:08Z

@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)

---------------------------------------------------------------------------

by Garfield-fr at 2012-07-23T20:28:44Z

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

Code: https://gist.github.com/4122efbe569e3c2c95c0

What about that ?

Thanks for your help

by stof at 2012-07-23T20:45:30Z

yep, this would be good (except for the naming which seems weird)

No problem to change this. I don't find a good name for this ?

---------------------------------------------------------------------------

by stof at 2012-07-23T20:47:57Z

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

---------------------------------------------------------------------------

by Garfield-fr at 2012-07-23T20:51:30Z

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

---------------------------------------------------------------------------

License of the code: MIT

Currently when passing in a bundle name that identifies a bundle that is a parent to another bundle, it will not return the reference for the requested bundle, but for the inheriting (even if that bundle has no configuration class).

F.e.
app/console config:dump-reference SymfonyCmfBlockBundle

will fail if there is a Bundle SandboxBlockBundle that has SymfonyCmfBlockBundle set as the parent.

[Yaml] Allow custom indentation level for nested nodes

YAML does not specify an absolute indentation level, but a consistent indentation of nested nodes only: http://yaml.org/spec/current.html#indentation%20space/

Projects that are generally using 2 spaces for indentation should be able to retain consistency with their coding standards by supplying a custom value for the new $indent parameter for Yaml::dump() and Dumper::dump().

The new parameter is a backwards-compatible API addition and defaults to the previous default of 4 (which was changed from 2 via PR #2242 only recently).

The old $indent parameter is renamed to $level, and remains to be used internally only.

This is indeed a BC break as the method signature changed in a non-BC way.

---------------------------------------------------------------------------

by fabpot at 2012-08-03T08:35:51Z

I think I would prefer to have a static method to be able to change the number of spaces to use on a global basis. It makes more sense and would prevent the BC break. What do you think?

---------------------------------------------------------------------------

by sun at 2012-08-03T13:23:23Z

Thanks for your feedback! — Took some time to think through the static proposal.  Here's what I think:

1. The call from DependencyInjection\Dumper\YamlDumper truly was a unexpected/nasty surprise for me.  That is, because it passes a parameter to Yaml\Dumper that is documented for internal use only, and the surrounding YamlDumper code generally hard-codes lots of assumptions of where exactly the nodes/collections will be output in the dumped YAML structure.  (I think that code can be simplified, cleaned up, and made faster at the same time (hence the todo), but indeed, that probably belongs into a separate issue.)
1. The essential problem with a static is closely bound to that though; a static property value for the indentation would "stick" and thus hi-jack the DependencyInjection\Dumper\YamlDumper, as it hard-codes and thus expects 4 spaces (contrary to any custom indentation).
1. Most code uses Yaml\Yaml as utility/helper service directly, so there'd be no clean way to prime the static with a custom value, aside from subclassing the entire thing - in which case this entire issue would sorta become moot, because at the point you're subclassing, you can as well go the extra mile and replace the entire Yaml\Dumper::dump() to implant the custom indentation level...
1. Another option would be to use a non-static Yaml\Dumper::$indent property, supplied through the constructor; i.e.:

        public function __construct($indent = 4)

  ...or alternatively, ::setIndentation(). Essentially requiring people to use and instantiate Yaml\Dumper directly, if they want to use a custom indentation.
1. Though in the end, I don't want to sound pedantic, but I *do* wonder a bit about the exact extent of the `@api` tags, as well as `@param`s that are explicitly documented as "internal use only"... :)  That is, because only Yaml\Yaml is tagged with `@api`, but nothing in Yaml\Dumper.  The same sorta applies to DependencyInjection\Dumper\YamlDumper::dump(), which is tagged with `@api`, but the :.addService() method being adjusted accordingly here is not.  So essentially, when taking those tags (plus the param's description) seriously and in a nitpicky way, then there is no BC break, since no one should rely on their exact implementation... ;)  (I perfectly realize that this is a long shot :))

So... depending on the final stance on the last point, I'd either move forward with the current proposal in this PR.  Otherwise, I'd suggest the non-static property on Yaml\Dumper - in which case we'd likely try to swap out the static Symfony\Component\Yaml\Yaml helper with a Drupal\Component\Yaml\Yaml in order to always instantiate the dumper with the custom indentation.  What do you think?

---------------------------------------------------------------------------

by sun at 2012-08-04T22:57:21Z

Alright.  While I believe I made some good points in my last comment, I've taken the fully backwards-compatible path:

- added the new $indent parameter only to Yaml::dump()
- added a new Dumper::$intendation property and Dumper::setIndentation() method, to control the indentation level within the scope of a single Dumper instance only.

Do you think this is acceptible? :)
