[TYPO3-core] FYI72: Bug 14967: [Caching framework] fileBackend testcase removes files in /sbin

[Christian Kuhn]

The following patch will be committed in 72 hours if nobody objects.

Type: Bugfix

Branches: trunk, 4.4, 4.3

BT: http://bugs.typo3.org/view.php?id=14967

Problem:
setCacheDirectoryThrowsExceptionOnNonWritableDirectory() tests if the 
fileBackend throws an exception if the target cache directory is not 
writable. This is done by using /sbin as target directory. The 
tearDown() method then removes the directory again. This will cause 
hazard if the tests are run by root.

Solution:
Create a random directory in typo3temp/, remove write permissions 
explicitly and clean up afterwards instead of using /sbin as test directory.

Regards
Christian
