Bug description: Static vars can't store ref to new instance
ola,
we've recently put in a set of methods in the binarycloud
core classes so they can enforce their singleton status.
An example:
// {{{ method GetInstance()
/**
* This method enforces this class's singleton
* status. It check s astatic var for an instance,
* if that instance exists a reference to it
* is returned. If it does not exist it is created
* and a reference is returned.
* @author hans lellelid, [EMAIL PROTECTED]
* @access public
*/
function &GetInstance() {
static $instance;
if(!isset($instance)) {
$instance = new Request();
}
return $instance;
}
// }}}
note the line:
$instance = new Request();
that means the instance is always overwritten.
we have to do that because:
$instance =& new Request();
results in a null $instance.
We believe this is a bug, but it's on the edge of possible
expected behavior.
thanks,
_alex
