Zend_Locale_Data::disableCache(true) is always reset

issue already filed as: http://framework.zend.com/issues/browse/ZF-11966

• Patch could be applied _OR_
• Manual should refer to Zend_Locale_Format::setOptions() instead

I am trying to get rid of the file cache in Zend_Locale_Data so i disabled it in my phpunit bootstrap. Upon closer inspection, i found out that simply creating a Zend_Date object from something invokes a chain of calls that ultimately leads to Zend_Locale_Format telling Zend_Locale_Data to set disableCache to false again.

_hacking Zend/Locale/Data.php:_

    /**
     * Disables the cache
     *
     * @param unknown_type $flag
     */
    public static function disableCache($flag)
    {
        self::$_cacheDisabled = (boolean) $flag;
        Zend_Debug::dump(self::$_cacheDisabled, __METHOD__);
        if (!self::$_cacheDisabled) {
            throw new Exception('ENABLED');
        }
    }

_yields output:_

D:\__project__\tests>phpunit --no-globals-backup
Zend_Locale_Data::disableCache
bool(true)

The options in Zend_Locale_Format overrides the disableCache option in Zend_Locale_Data:

private static $_options = array(
    'disableCache'  => false,
    // …
);

public static function getDate($date, array $options = array())
{
    $options = self::_checkOptions($options) + self::$_options;
    // …
}

private static function _checkOptions(array $options = array())
{
    // …
    case 'disablecache' :
        Zend_Locale_Data::disableCache($value);
        break;
    // …
}

Maybe a soluation:

class Zend_Locale_Format
{
    private static $_options = array(
        // …
        'disableCache'  => null,
        // …
    );

    private static function _checkOptions(array $options = array())
    {
        // …
        case 'disablecache' :
            if (null !== $value) {
                Zend_Locale_Data::disableCache($value);
            }
            break;
        // …
    }
}

Yes that should work. Basically the call on Zend_Locale_Data is primary and the option of Zend_Locale_Format is secondary (only calling it again). So assume that it is not set there. With your solution it would work for users that set it with either way.
