Byte order is not compatible at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/_retrieve.al) line 380, at /usr/share/perl/5.12/Memoize/Storable.pm line 21

Could not unmemoize function `lookup_svn_merge', because it was not memoized to begin with at /usr/lib/git-core/git-svn line 3213

The solution is so simple

Add the line

$Storable::interwork_56_64bit = 1;

near the top of /usr/lib/git-core/git-svn, just after the version definition.

You have to create a database before use it. This implementation uses PHP’s HTTP stream wrapper, so you have to enable allow_url_fopen ini directive.

This is a simplified version of the code, I use in greebo:

static function register($base_dir)
{
  $base_dir = rtrim($base_dir, '/').'/';

  spl_autoload_register(function($class) use($base_dir) {
    $class = str_replace('\\', '/', $class.'.php');
    $file = $base_dir.ltrim($class, '/');
    if (file_exists($file)) {
      require $file;
    }
  });
}

Let’s see the benefit of this pattern with Doctrine.

Suppose we have a gallery with images. Every gallery have a “preview” image (one from the its images), which represents the gallery in lists (or anywhere else). How can we handle the situation when a gallery has no preview image? (We want to show a “no-image.jpg” there.)

Let’s start with the schema:

Gallery:
  tableName: gallery
  columns:
    id:
      type: integer
      unsigned: true
      notnull: true
      primary: true
      autoincrement: true
    name:
      type: string(200)
    preview_image_id:
      type: integer
      unsigned: true
      notnull: true
  relations:
    PreviewImage:
      local: preview_image_id
      foreign: id
      type: one
      class: Image
Image:
  tableName: image
  columns:
    id:
      type: integer
      unsigned: true
      notnull: true
      primary: true
      autoincrement: true
    gallery_id:
      type: integer
      unsigned: true
      notnull: true
    file:
      type: string(255)
    title:
      type: string(255)
  relations:
    Gallery:
      local: gallery_id
      foreign: id
      foreignAlias: Images
      onDelete: CASCADE

We have a working database schema, where gallery has a foreign key (preview_image_id) to its preview image. The set up of this field is up to the developers. What will happen when we want to show the preview image at this state of model?

First, we add some code to Image model class, to simplify the image handling.

class Image extends BaseImage
{
  const TYPE_ORIGINAL = 1;
  const TYPE_THUMBNAIL = 2;

  // ...
  public function getImageName($type = self::TYPE_ORIGINAL)
  {
    $info = pathinfo($this->file);
    $names = array(
      self::TYPE_ORIGINAL => $this->file,
      self::TYPE_THUMBNAIL => $info['filename'].'_thumb.'.$info['extension'],
    );

    if (!isset($names[$type]))
    {
      throw new InvalidArgumentException();
    }

    return $names[$type];
  }

  public function getImagePath($absolute = true)
  {
    $path = '/uploads/images';
    $absolute_path = sfConfig::get('sf_web_dir').$path;

    if (!file_exists($absolute_path))
    {
      mkdir($absolute_path, 0777, true);
      chmod($absolute_path, 0777);
    }

    return $absolute ? $absolute_path : $path;
  }

  public function getImageFile($type = self::TYPE_ORIGINAL, $absolute = false)
  {
    return $this->getImagePath($absolute).'/'.$this->getImageFile($type);
  }
  // ...
}

So what will happen when we want to show the preview image?

<img src="<?= $gallery->PreviewImage->getImageFile(); ?>" />

It depends on. If we have a setted up preview image, it works well. If not, we have a fatal error. So with this model, we always have to check the foreign field (preview_image_id), it’s a null value or an object. It would be convenient we just use that object ($gallery->PreviewImage), and the object can handle the special case (the null object).

We have to do two things for that:

1. set up Doctrine to give a “fresh” Image object, when we call $gallery->PreviewImage (this will be the null object)
2. have to handle the case when file field is empty

The first constraint can be done easily. Just remove the notnull instruction from the preview_image_id field of Gallery model. With this setup the Doctrine will return a new Image instacne.

The second constraint can be done by small modification of our model code:

class Image extends BaseImage
{
  // ...
  public function getImageName($type = self::TYPE_ORIGINAL)
  {
    if ($this->file)
    {
      $info = pathinfo($this->file);
      $names = array(
        self::TYPE_ORIGINAL => $this->file,
        self::TYPE_THUMBNAIL => $info['filename'].'_thumb.'.$info['extension'],
      );
    }
    else
    {
      $names = array(
        self::TYPE_ORIGINAL => '/images/no_image.jpg',
        self::TYPE_THUMBNAIL => '/images/no_image_thumb.jpg',
      );
    }

    if (!isset($names[$type]))
    {
      throw new InvalidArgumentException();
    }

    return $names[$type];
  }

  public function getImageFile($type = self::TYPE_ORIGINAL, $absolute = false)
  {
    if (!$this->file)
    {
      return $this->getImageName($type);
    }
    return $this->getImagePath($absolute).'/'.$this->getImageFile($type);
  }
  // ...
}

That’s it.
