Summary

0000799: xDebug Function Traces reports Base Class instead of Object Name

Description

When running a function trace xDebug reports on the base class an object's method is defined in, and not on the type of the object instance. Derick's comments on this Stack Overflow thread indicate this is not normal behavior

http://stackoverflow.com/questions/9727414/xdebug-report-on-objects-during-function-trace#comment12422053_9727414 [^]

Steps To Reproduce

1. Create the following PHP program

    xdebug_start_trace();
    abstract class A
    {
        abstract function foo();

        public function bar()
        {
            echo "A Test","\n";
        }
    }

    class B extends A
    {
        public function foo()
        {
        }
    }

    $test = new B;
    $test->bar();

2. Execute program by visiting it in a web browser

3. View Trace File

Expected Output:

    TRACE START [2012-03-18 22:32:29]
        0.0023 642888 -> B->bar() /path/to/xdebug.php:21
        0.0027 8512
    TRACE END [2012-03-18 22:32:29]

Actual Output

    TRACE START [2012-03-18 22:32:29]
        0.0023 642888 -> A->bar() /path/to/xdebug.php:21
        0.0027 8512
    TRACE END [2012-03-18 22:32:29]

The output discrepancy is B->bar() vs. A->bar(). The object was instantiated with a class "B", but xDebug reports the base class, A->Bar();

Additional Information

Issue happen on OS X 10.6.8, phpinfo reports the xDebug version as 2.2.0rc1, happens with Stock OS X PHP with an xDebug installed via pecl. Full phpinfo() output printed and attached as PDF.
