[xdebug-general] Re: use of XDEBUG_CC_UNUSED

Okay, I see what you mean, and I can understand why this is the case. I'm
not
sure I agree from a code-coverage point of view, but I think this has more
to
do with the Zend engine model than with your code. I'm not blaming you ;)

I have, however, another XDEBUG_CC_UNUSED related nag for you :)
The following code:

<?
    xdebug_start_code_coverage(XDEBUG_CC_UNUSED);
    class b
    {
        function a()
        {
            return NULL;
        }
    };
    $cc = xdebug_get_code_coverage();
    xdebug_stop_code_coverage();
    var_dump($cc);
?>

Produces:

array(1) {
  ["/var/www/experiment/xdebug_cc.php"]=>
  array(2) {
    [4]=>
    int(1)
    [10]=>
    int(1)
  }
}

Is this simply a case of missing opcode overrides? (By the way, the class
starting on
line 4 instead of 3 is probably a PHP bug, as I've seen this in their
Reflection API as well,
it does work when "b" is a subclass of another class)

Warm regards,
