[FLOW3-general] Exception when executing 'flow3 cache flush' and opening welcome page

Mon Feb 1 16:13:15 CET 2010

I could workaround the problem. After modifing the 'remove()' method
in F3\FLOW3\Cache\Backend\FileBackend.php FLOW3 works as expected.

/**
* Removes all cache entries matching the specified identifier.
* Usually this only affects one entry.
*
* @param string $entryIdentifier Specifies the cache entry to remove
* @return boolean TRUE if (at least) an entry could be removed or
FALSE if no entry was found
* @author Robert Lemke <robert at typo3.org>
* @api
*/
public function remove($entryIdentifier) {
$pathAndFilename = $this->cacheDirectory . $entryIdentifier;
if (!file_exists($pathAndFilename)) return FALSE;
if (unlink ($pathAndFilename) === FALSE) return FALSE;
$tagFilesByEntry = $this->findTagFilesByEntry($entryIdentifier);
if(false === $tagFilesByEntry) return FALSE;
foreach($tagFilesByEntry as $pathAndFilename) {
if (!file_exists($pathAndFilename)) return FALSE;
if (unlink ($pathAndFilename) === FALSE) return FALSE;
}
$this->systemLogger->log(sprintf('Cache %s: removed entry "%s".',
$this->cacheIdentifier, $entryIdentifier), LOG_DEBUG);
return TRUE;
}

I have added a check if findTagFilesByEntry returns false. Because
this triggered the error in remove.
But i think it normally should return an empty array, but in my case
it returns false - so i think glob is triggering an error.
Does someone know why this happens?

Thanks
