|
|
|
|
==================================================
|
|
Deprecation: #85858 - GeneralUtility::clientInfo()
|
|
==================================================
|
|
|
|
See :issue:`85858`
|
|
|
|
Description
|
|
===========
|
|
|
|
The helper method :php:`GeneralUtility::clientInfo()` responsible for
|
|
parsing the server variable :php:`$_SERVER['HTTP_USER_AGENT']` has been marked
|
|
as deprecated.
|
|
|
|
This method is not up-to-date with current browser headers, and in light of
|
|
browser that are able to fake the HTTP_USER_AGENT the detection is not practical
|
|
anymore.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
Calling the method directly will trigger a PHP :php:`E_USER_DEPRECATED` error.
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
Any TYPO3 installation with extensions directly calling this method.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
Depending on the use-case, it is best to use the PSR-7-based request object,
|
|
if available in the context, or `$_SERVER['HTTP_USER_AGENT']` to detect a
|
|
specific browser/client user agent.
