Breaking: #88638 - Streamlined SoftRefParser reference lookup

See forge#88638


The Soft Reference Parser is a registry to allow to find parsers (PHP Objects), for a given Parser Type (images, internal links, email links) to keep track of referenced records within arbitrary data (e.g. RTE text-fields).

Parsers can be added or overridden via the hook registry $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['GLOBAL']['softRefParser'][$parserType].

Previously, the API method for fetching the proper parsers TYPO3\CMS\Backend\Utility\BackendUtility::softRefParserObj() kept a runtime cache of created objects per type within a global PHP array (T3_VAR). This allowed to create objects only once, even if there are multiple necessary parts required.

TYPO3's Core SoftRefParser does not keep any state, but the class now has a SingletonInterface, which means that the object is now a re-used object as before.


Calling the SoftRefParser factory method does not keep state of the parser objects via $GLOBALS['T3_VAR']['softRefParser'] anymore.

Instead, SingletonInterface is recommended for re-using SoftRefParser objects if they need to keep state.

Affected Installations

TYPO3 installations with extensions that use the API with custom parsers, or the global variable directly.


Replace the global variable access via the API call to TYPO3\CMS\Backend\Utility\BackendUtility, if this is applicable.

If a custom parser is in use, it is recommended to evaluate whether it contains re-usable data and switch to SingletonInterface instead.
