TYPO3 Core

Yes, it is still the case in 6.0.11.
Double slash is still passed to TYPO3\CMS\Core\Utility\GeneralUtility::fixPermissions()

Problem still exists in 6.1.7. Couldn't test in 6.2.x yet.

• set $GLOBALS['TYPO3_CONF_VARS']['BE']['folderCreateMask'] = '2775' in LocalConfiguration.php/AdditionalConfiguration.php
• create a folder with Filelist module in Backend
• created folder should have permissions according to folderCreateMask

• typo3/sysext/core/Classes/Resource/Driver/Localdriver.php->createFolder()
• \TYPO3\CMS\Core\Utility\GeneralUtility::mkdir($this->getAbsoluteBasePath() . $newFolderPath);
• $this->getAbsoluteBasePath() has a trailing slash
• $newFolderPath has a leading slash
• this causes resulting paths with double slash, e.g. "[...]/fileadmin//test_create_folder/"

• the LocalDriver->createFolder() function calls GeneralUtility::mkdir()
• GeneralUtility::mkdir() calls self::fixPermissions()
• self::fixPermissions() calls self::isAllowedAbsPath($path)
• self::isAllowedAbsPath($path) fails because the $path contains '//' and returns false
• fixPermissions() function aborts and does not apply the folderCreateMask setting to the newly created folder

• typo3/sysext/core/Classes/Resource/Driver/Localdriver.php->createFolder() line 212 (@6.1.7)
• use LocalDriver->getAbsolutePath() which takes care of correct concatenation
• before: \TYPO3\CMS\Core\Utility\GeneralUtility::mkdir($this->getAbsoluteBasePath() . $newFolderPath);
• after: \TYPO3\CMS\Core\Utility\GeneralUtility::mkdir($this->getAbsolutePath($newFolderPath));
