DDC-46: Invalid MySQL column mappings

[doctrinebot]

Jira issue originally created by user mcurcio:

I have a table for storing sessions in the database, schema is:

CREATE TABLE IF NOT EXISTS Session (
id varchar(255) NOT NULL,
data longtext NOT NULL,
created datetime NOT NULL,
accessed datetime NOT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

With the following code, I receive an error about an unknown 'clob' column. I believe the issue is related to the mappings in DBAL/Schema/MySQLSchemaManager::_getPortableTableColumnDefinition

Code:
$cmf = $em->getMetadataFactory();
$driver = $em->getConfiguration()->getMetadataDriverImpl();

    $driver->setClassDirectory(<model_path>);

    $classes = array();
    $preloadedClasses = $driver->preload();
    foreach ($preloadedClasses as $className) {
        $classes[] = $cmf->getMetadataFor($className);
    }

    $schemaTool = new \Doctrine\ORM\Tools\SchemaTool($em);

foreach ($schemaTool->getUpdateSchemaSql($classes) as $sql) {
        echo $sql.'<br />';
    }

Error:
exception 'Doctrine\Common\DoctrineException' with message 'Unknown column type ('clob')' in /var/www/tec-expo.com/development/libraries/Doctrine/Common/DoctrineException.php:109

This should be fixed now in HEAD. Can you confirm that?
