CiviCRM Community Forums (archive)

I have created a payment processor plugin for Chase Paymentech that has been running well for about three months. I am now running into problems after upgrading to 3.3.3 from 3.2.3.

My upgrade process went off without any errors, but I am getting an error after upgrading
Fatal error: Maximum function nesting level of '100' reached, aborting! in \path\to\drupal\sites\all\modules\civicrm\CRM\Core\Config.php on line 95
It looks like CRM_Core_Payment::singleton( ) is being called repeatedly until the max recursion level is reached, but I don't understand why.

In the release announcement for 3.3.3 there is a note that it includes the "First take on extension mechanism for CiviCRM, allowing creation and distribution of plugins (payment processors, custom search, custom report templates for now)". Does this effect the way payment processors are implemented? The documentation appears to be the same, but if it needs to be updated, I would be happy to help.

Thanks for any assistance.

this came up on IRC recently. You need a singleton function in your payment code, something similar to:

    /**                                                                                                                                     
     * singleton function used to manage this object                                                                                       
     *                                                                                                                                     
     * @param string $mode the mode of operation: live or test                                                                             
     *                                                                                                                                     
     * @return object                                                                                                                       
     * @static                                                                                                                             
     *                                                                                                                                     
     */
    static function &singleton( $mode, &$paymentProcessor ) {
        $processorName = $paymentProcessor['name'];
        if (self::$_singleton[$processorName] === null ) {
            self::$_singleton[$processorName] = new CRM_Core_Payment_PaypalImpl( $mode, $paymentProcessor );
        }
        return self::$_singleton[$processorName];
    }

i'm not sure the history / origins of why this was introduced

If the problem is the below, that has been introduced to get rid of CRM_Contribute_Payment_ProcessorName and CRM_Event_Payment_ProcessorName classes which basically contained the singleton methods only.
