Description

Hi,

we have noticed that there is a problem with uft8 filenames of images when they are processed using imageLinkWrap.

The problem starts in the method TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::getImgResource:

    public function getImgResource($file, $fileArray)
    {
...
                            'origFile' => $fileObject->getPublicUrl(),                   // <<<<------
                            'origFile_mtime' => $fileObject->getModificationTime(),
                            // This is needed by \TYPO3\CMS\Frontend\Imaging\GifBuilder,
                            // in order for the setup-array to create a unique filename hash.
                            'originalFile' => $fileObject,
                            'processedFile' => $processedFileObject
...

The value $info['originalFile'] will be removed later in the method TYPO3\CMS\Frontend\ContentObject\ImageContentObject::cImage:

...
        // Remove file objects for AssetCollector, as it only allows to store scalar values
        unset($info['originalFile'], $info['processedFile']);
        GeneralUtility::makeInstance(AssetCollector::class)->addMedia(
            $source,
            $info
        );
...

This means that the public path is used to call the imageLinkWrap function in the method TYPO3\CMS\Frontend\ContentObject\ImageContentObject::cImage:

...
        } elseif ($conf['imageLinkWrap']) {
            $originalFile = !empty($info['originalFile']) ? $info['originalFile'] : $info['origFile'];
            $theValue = $this->cObj->imageLinkWrap($theValue, $originalFile, $conf['imageLinkWrap.']);
        }
...

Which ultimately leads to a fatal result when determining the file object later in the method TYPO3\CMS\Core\Resource\Driver\LocalDriver::getFileInfoByIdentifier:

...
        $absoluteFilePath = $this->getAbsolutePath($fileIdentifier);
        // don't use $this->fileExists() because we need the absolute path to the file anyways, so we can directly
        // use PHP's filesystem method.
        if (!file_exists($absoluteFilePath) || !is_file($absoluteFilePath)) {
            throw new \InvalidArgumentException('File ' . $fileIdentifier . ' does not exist.', 1314516809);
        }
...

A workaround could be that the identifier is urldecoded after it has been entered in the ResourceFactory or that the public path for the array index 'origFile' is not used at all but the real path is used.

Thanks for fixing.

Hi,

this bug still exists in the current release 10.4.20. To reproduce this:

1. Activate UTF8 filesystem in install tool by setting [SYS][UTF8filesystem] = true and [SYS][systemLocale] = de_DE.utf-8 (or any other utf8 locale fitting your server configuration).

2. Upload an image file to fileadmin/user_upload/nachhaltig-und-zuverlässig.png

3. Create TS template with:

page = PAGE
page.10 = IMAGE
page.10 {
  imageLinkWrap = 1
  imageLinkWrap.enable = 1
  file = fileadmin/user_upload/nachhaltig-und-zuverlässig.png
}

4. Load frontend. This leads to the following exception:

#1314516809 InvalidArgumentException
File /fileadmin/user_upload/nachhaltig-und-zuverl%C3%A4ssig.png does not exist.

5. Set imageLinkWrap = 0 and reload frontend. Image is rendered as expected.

I think a fix of this bug is quite important since it breaks image rendering in the frontend. We can not upgrade to 10.4 at the moment because of this bug.
