Deprecation: #89868 - Remove reqCHash functionality for plugins¶
Extbase and pi-based plugins that are non-cacheable could previously require the validation of the cHash GET parameter in order to validate GET parameters against the "cHash".
In Extbase plugins, this could be configured via a TypoScript feature toggle (enabled by default):
config.tx_extbase.features.requireCHashArgumentForActionArguments = 1
In Pi-based plugins the public property
was used to enable the cHash validation for non-cacheable plugins.
Both plugin systems triggered the method
validated relevant GET parameters. However, the
PageArgumentValidator PSR-15 middleware now
always validates the cHash, so a plugin does not need to know about cHash validation anymore and
therefore does not need to set the option.
This means the options are not needed anymore, as the validation already happens during the Frontend request handling process. The options are removed.
In addition, the method
TypoScriptFrontendController->reqCHash() has been marked as deprecated and
is not in use anymore.
Setting the option in Extbase or Pi-Base has no effect anymore.
Calling the PHP method
will trigger a PHP
Internal classes such as the
CacheHashEnforcer are removed.
TYPO3 installations with plugins, where one of the options is set, or where the PHP method is called directly.
Remove the options / flags as they have no effect in TYPO3 v10 anymore.
Calling the method directly is also not needed, as the PageArgumentValidator is executing this validation now at every request.
