Breaking: #52156 - Replaced JumpURL features with hooks

See forge#52156

Description

JumpURL handling

The generation and handling of JumpURLs has been removed from the frontend extension and has been moved to a new core extension called "jumpurl".

URL handler hooks

New hooks were introduced in TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer and \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController that allow custom URL generation and handling.

This is how you can register a hook for manipulating URLs during link generation:

// Place this in your ext_localconf.php file
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['urlProcessing']['urlHandlers']['myext_myidentifier']['handler'] =
	\Company\MyExt\MyUrlHandler::class;

// The class needs to implement the UrlHandlerInterface:
class MyUrlHandler implements \TYPO3\CMS\Frontend\Http\UrlHandlerInterface {}
Copied!

This is how you can handle URLs in a custom way:

// Place this in your ext_localconf.php file
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['urlProcessing']['urlProcessors']['myext_myidentifier']['processor']
	= \Company\MyExt\MyUrlProcessor::class;

// The class needs to implement the UrlProcessorInterface:
class MyUrlProcessor implements \TYPO3\CMS\Frontend\Http\UrlProcessorInterface {}
Copied!

External URL page handling

The core functionality for redirecting the user to an external URL when he hits a page with doktype "external" is moved from the \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController to the \TYPO3\CMS\Frontend\Page\ExternalPageUrlHandler class.

ResourceStorage adjustment

The method \TYPO3\CMS\Core\Resource\ResourceStorage::dumpFileContents() accepts an additional parameter for overriding the mime type that is sent in the Content-Type header when delivering a file.

Impact

Unless the jumpurl extension is installed, no JumpURL related feature will work anymore.

If an extension tightly integrates into the JumpURL process it might break, because some of the related methods have been removed, disabled or changed.

These methods have been removed and their functionality has been moved to the new jumpurl extension:

\TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::locDataJU()

\TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::locDataCheck()

The $initP parameter of the method \TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::getMailTo() has been removed.

The method \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::setExternalJumpUrl() has been marked as deprecated and is an alias for the new initializeRedirectUrlHandlers() method that does no jumpurl handling any more. The new method only checks if the current page is a link to an external URL and sets the redirectUrl property.

The method \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::jumpUrl() has also been marked as deprecated and is an alias for the new redirectToExternalUrl() method. The jumpurl handling has been removed from this method. It loops over all registered URL handlers and handles the redirection to the redirectUrl.

Affected installations

All CMS 7.4 installations that use the JumpURL features or that use Extensions that rely on these features or one of the removed methods.

Migration

If you want to use the JumpURL features you need to install the jumpurl extension. Your configuration should work as before.

Please note that the configuration of the filelink TypoScript function has changed. Passing the jumpurl parameter in the configuration has been marked as deprecated and will be removed in future versions.

You can now pass arbitrary configuration options for the typolink call that is used to generate the file link in the typolinkConfiguration parameter:

lib.myfilelink = TEXT
lib.myfilelink.value = fileadmin/myfile.txt
lib.myfilelink.filelink {
  typolinkConfiguration.jumpurl = 1
  typolinkConfiguration.jumpurl.secure = 1
}
