In revision https://github.com/Qafoo/changetrack/tree/747d018fc042f05d44c13085c4e930d6dff6b31f I performed the following rename:

src/main/Qafoo/ChangeTrack/TemporaryDirectory.php -> src/main/Qafoo/ChangeTrack/WorkingDirectory.php

This resulted in the following diff:

--- a/src/main/Qafoo/ChangeTrack/WorkingDirectory.php
+++ b/src/main/Qafoo/ChangeTrack/WorkingDirectory.php
@@ -5,5 +5,5 @@
use Symfony\Component\Filesystem\Filesystem;

-class TemporaryDirectory
+class WorkingDirectory
{
    /**

While the diff is correct, it misses the reference to the class in https://github.com/Qafoo/changetrack/blob/747d018fc042f05d44c13085c4e930d6dff6b31f/src/main/Qafoo/ChangeTrack/Analyzer.php#L48
