The problem with non-legacy mode is that the backend uses the same filename for the system semaphore file and for the shared memory file. What happens is that when we try to call attach(), a semaphore is created. Later in attach() we set unix_key, because ftok() returns a valid handle (it uses the file which was created for semaphore). After that, an attempt to actually attach to a shared memory fails, but no clean-up is done. So, a later call to create() sees that unix_key is already valid, but it cannot properly clean it, because it does not actually refer to any shared memory. Fix it by cleaning up unix_key and nativeKeyFile if shmget() call in attach() fails.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
