Description
Hi,
While connecting a quick SignalSlot to the Dispatcher using closure this can cause page rendering problems.
How to reproduce:
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\SignalSlot\\Dispatcher')->connect(
TYPO3\CMS\Core\Tree\TableConfiguration\TableConfiguration\DatabaseTreeDataProvider::class,
\TYPO3\CMS\Core\Tree\TableConfiguration\DatabaseTreeDataProvider::SIGNAL_PostProcessTreeData,
function(DatabaseTreeDataProvider $dataProvider, $treeData) {
// my quick changes
}
);
Now add a Text with Image and an plugin which is an USER_INT.
The text with image load an FAL image in cObj, the USER_INT tries to serialize the cObj.
This results in the error: Serialization of 'Closure' is not allowed
I do not mind solving this issue myself, however I don't know on what level I should fix this.
1) Make sure cObj is serializable (using $this->cObj->setCurrentFile(null); at the end of \TYPO3\CMS\CssStyledContent\Controller\CssStyledContentController::render_textpic())
2) Make sure Closures are not allowed in signal slots (using validation in connect())
Kind regards,
Benjamin
