| Summary | 0001710: Doubled recursion count in kcachegrind on select recursive function |
|---|
| Description | I tried profiling a recursive function with a little test script. When viewing the cachegrind output in kcachegrind I can see the correct number of function calls when clicking the main entry point in the call graph (27).
However, when i click the recursive function, it shows doubled count (54) which I did not expect. |
|---|
| Steps To Reproduce | 1. Run the following script in documentRoot with profiling enabled.
2. Inspect the output with kcachegrind.
<?php
$list = ['one', 'two', 'three'];
foreach ($list as $item) {
outputWithRecursion($item, 10);
}
function outputWithRecursion(string $item, int $countdown): void
{
$countdown--;
if ($countdown > 0) {
echo sprintf('not yet (%d)...', $countdown);
outputWithRecursion($item, $countdown);
} else {
echo sprintf('Finally there: %s(%d)
', $item, $countdown);
}
