Detailed Description

Reference index processing and relation extraction

NOTICE: When the reference index is updated for an offline version the results may not be correct. First, lets assumed that the reference update happens in LIVE workspace (ALWAYS update from Live workspace if you analyze whole database!) Secondly, lets assume that in a Draft workspace you have changed the data structure of a parent page record - this is (in TemplaVoila) inherited by subpages. When in the LIVE workspace the data structure for the records/pages in the offline workspace will not be evaluated to the right one simply because the data structure is taken from a rootline traversal and in the Live workspace that will NOT include the changed DataStructure! Thus the evaluation will be based on the Data Structure set in the Live workspace! Somehow this scenario is rarely going to happen. Yet, it is an inconsistency and I see now practical way to handle it - other than simply ignoring maintaining the index for workspace records. Or we can say that the index is precise for all Live elements while glitches might happen in an offline workspace? Anyway, I just wanted to document this finding - I don't think we can find a solution for it. And its very TemplaVoila specific.

◆ getRecordRawCached()

array false TYPO3\CMS\Core\Database\ReferenceIndex::getRecordRawCached	(	string	$tableName,
		int	$uid
	)

protected

Gets one record from database and stores it in an internal cache (which expires along with object lifecycle) for faster retrieval

Assumption:

‪This method is only used from within delegate methods and so only caches queries generated based on the record being indexed; the query to select origin side record is uncached
‪Origin side records do not change in database while updating the reference index
‪Origin record does not get removed while updating index
‪Relations may change during indexing, which is why only the origin record is cached and all relations are re-process even when repeating indexing of the same origin record

Please note that the cache is disabled by default but can be enabled using $this->enableRuntimeCaches() due to possible side-effects while handling references that were changed during one single request.

Parameters

string	$tableName
int	$uid

Returns: ‪array|false

string bool array TYPO3\CMS\Core\Database\ReferenceIndex::setReferenceValue	(	$hash,
		$newValue,

		$bypassWorkspaceAdminCheck = `false`
	)

Setting the value of a reference or removing it completely. Usage: For lowlevel clean up operations! WARNING: With this you can set values that are not allowed in the database since it will bypass all checks for validity! Hence it is targeted at clean-up operations. Please use DataHandler in the usual ways if you wish to manipulate references. Since this interface allows updates to soft reference values (which DataHandler does not directly) you may like to use it for that as an exception to the warning above. Notice; If you want to remove multiple references from the same field, you MUST start with the one having the highest sorting number. If you don't the removal of a reference with a lower number will recreate an index in which the remaining references in that field has new hash-keys due to new sorting numbers - and you will get errors for the remaining operations which cannot find the hash you feed it! To ensure proper working only admin-BE_USERS in live workspace should use this function

Parameters

string	$hash	‪32-byte hash string identifying the record from sys_refindex which you wish to change the value for
mixed	$newValue	‪Value you wish to set for reference. If NULL, the reference is removed (unless a soft-reference in which case it can only be set to a blank string). If you wish to set a database reference, use the format "[table]:[uid]". Any other case, the input value is set as-is
bool	$returnDataArray	‪Return $dataArray only, do not submit it to database.
bool	$bypassWorkspaceAdminCheck	‪If set, it will bypass check for workspace-zero and admin user

Returns: ‪string|bool|array FALSE (=OK), error message string or array (if $returnDataArray is set!)

◆ updateRefIndexTable()

array TYPO3\CMS\Core\Database\ReferenceIndex::updateRefIndexTable	(	$tableName,
		$uid,
		$testOnly = `false`
	)

Call this function to update the sys_refindex table for a record (even one just deleted) NOTICE: Currently, references updated for a deleted-flagged record will not include those from within FlexForm fields in some cases where the data structure is defined by another record since the resolving process ignores deleted records! This will also result in bad cleaning up in DataHandler I think... Anyway, that's the story of FlexForms; as long as the DS can change, lots of references can get lost in no time.

Parameters

string	$tableName	‪Table name
int	$uid	‪UID of record
bool	$testOnly	‪If set, nothing will be written to the index but the result value will still report statistics on what is added, deleted and kept. Can be used for mere analysis.

Returns: ‪array Array with statistics about how many index records were added, deleted and not altered plus the complete reference set for the record.

Definition of tables to exclude from the ReferenceIndex

Only tables which do not contain any relations and never did so far since references also won't be deleted for these. Since only tables with an entry in $GLOBALS['TCA] are handled by ReferenceIndex there is no need to add *_mm-tables.
