Important: #91095 - Various methods and properties of Backend-related Core APIs now internal

See forge#91095

Description

Some cornerstones of TYPO3 Core have been kept and migrated since before TYPO3 v4.0. This was when PHP 5 and class visibility was not even available.

Most classes contain various methods which have been marked as "public", making it public API for TYPO3, even though their usages should only be available for TYPO3 Core.

All methods are now marked as "@internal", as official Core API should be used instead.

DataHandler class properties and methods: Except for the public methods that are still available, it is highly recommended to use DataHandler as defined in the official documentation.

The following properties and methods are now marked as internal:

• DataHandler->checkSimilar

The reason for this long list is this: If the DataHandler API is not called via start() and the process_* methods, but rather the methods would be called directly, certain hooks would be disabled completely, resulting in a huge data inconsistency.

At this point, it is highly recommended to use the official API of DataHandler as written in the main documentation.

Various BackendUtility class methods are called statically, but cannot guarantee any Context. Short-hand functions for TCA or Database Queries are now better suited by using the appropriate Database Restrictions.

• BackendUtility::purgeComputedPropertiesFromRecord()

• BackendUtility::purgeComputedPropertyNames()

• BackendUtility::splitTable_Uid()

• BackendUtility::BEenableFields()

• BackendUtility::openPageTree()

• BackendUtility::getUserNames()

• BackendUtility::getGroupNames()

• BackendUtility::blindUserNames()

• BackendUtility::blindGroupNames()

• BackendUtility::getCommonSelectFields()

• BackendUtility::helpTextArray()

• BackendUtility::helpText()

• BackendUtility::wrapInHelp()

• BackendUtility::softRefParserObj()

• BackendUtility::explodeSoftRefParserList()

• BackendUtility::selectVersionsOfRecord()

• BackendUtility::fixVersioningPid()

• BackendUtility::movePlhOL()

• BackendUtility::getLiveVersionIdOfRecord()

• BackendUtility::versioningPlaceholderClause()

• BackendUtility::getWorkspaceWhereClause()

• BackendUtility::wsMapId()

• BackendUtility::getMovePlaceholder()

• BackendUtility::getBackendScript()

• BackendUtility::getWorkspaceWhereClause()

BackendUserAuthentication a.k.a. $GLOBALS['BE_USER'] contains a lot of internal calls and properties which are only used for within TYPO3 Core or to keep state. This should not be exposed in the future anymore, especially when a more flexible permission system might get introduced. The affected properties and methods are:

• BackendUserAuthentication->includeGroupArray
