Description

Steps to reproduce:

  1. Use an image file in you template that comes from the fallback storage (which uses typo3temp/_processed_/ as processing folder)
  2. make sure the imge gets resized (e.g. by setting the width property)
  3. Prevent write access for the Webserver to the TYPO3 root folder, but allow write access to typo3temp/
  4. Open the Frontend

You will get an Exception:

#1323059807: You are not allowed to create directories in the folder "/"

The problem occurs during this call:

TYPO3\CMS\Core\Resource\ResourceStorage::createFolder("typo3temp/_processed_/")

Even if the typo3temp/ folder exists the ResourceStorage will check if the root directory is writable.

I would suggest to add a new createFolderRecursive method, which accepts an array of folder names that are created recursively. This would allow a permission check for every directory in the path, but only if the directory does not exist already.

Hello,

i don't know if this is the right place for posting following hint...

But in my case (Upgrade from 4.6 to 4.7 and then 4.7 to 6.2) clicking the fileadmin shows this error... The same when i try to select an image (in the occurring popup) via normal Image CE.

After several "comment-out" tries (Patch 1-4) in /Core/Classes/Resource/ResourceStorage.php nothing helped. Later i figured out that the problem was wrongly merged Database/File Mounts. They wasn't configured "relative" and the target was "/" and not "fileadmin/".

After changing this, the resource error doesn't appear anymore. the strange thing is - it's a windows xampp dev env.

Could this be a solution or do i don't understand the Bug-Report again?!

Cheers and best regards
Guido

This problem also happens with "Help > About modules" and "Help > About TYPO3 CMS".

This issue boils down to one of the new concepts in 6.2:

  • New TYPO3 version don't assume that "typo3temp" must exist. If it doesn't it will create it.
  • Therefore newer TYPO3 versions must have write permissions to the webroot "/" where typo3temp resides in.

Of course it sounds logically that it should also work when typo3temp/ has been manually created. But it currently doesn't because of an issue in ResourceStorage.php

The solution would be to fix method "checkFolderActionPermission" in ResourceStorage.php

In fact this method seems to be incomplete for its purpose. Besides the $action parameter it only gets one other parameter "$folder". But for many operations like "copy" or "move" and also "add" two parameters should be required: The source and the target. In the case of "add" both parameters could get concatenated and then traversed backwards to find the first non-existing folder. Those parent folder would have to be writable.

The method "createFolder" is thus used in a way that it must be able to handle recursive creation of folders. If typo3temp doesn't exists, createFolders would be responsible for recursively creating it.

For this purpose it would be necessary to operate on the parts of a folder path. So I assume there is a method "splitPath" missing for the drivers.

Files in a filesystem tend to be organized in folders and files. A file can get specified by a path. So there needs to be a way to split up a path into its particles: instances of "Folder" and "File" in the case of FAL.

Agree with Bernhard Kraft. It should find the first existing parent and check their rights instead of the root folder.

In my case we have a custom script deleting all files in typo3temp/, but not the folder itself. After this operation TYPO3 fails to re-create typo3temp/_processed_/ because it does not have rights on typo3temp parent, which actually has nothing to do with the creation of typo3temp subfolders.
