Feature: #79438 - Add configuration option to disable validation of stored records

See Issue #79438

Description

Two configuration options have been added to the Install Tool, which are used when saving records using the DataHandler.

The first option allows to disable the check if the contents of a record match the data that should have been written after saving it to the database for the whole TYPO3 installation. This allows a speed-up especially when inserting/copying large amounts of data at the cost of possible differences, if values could not be written as requested. This may happen, if e.g. data types do not match or columns are too small to store the data.

Disable checking the stored records:

$GLOBALS['TYPO3_CONF_VARS']['BE']['checkStoredRecords'] = false;

If checking the stored records is enabled, the second option allows to make the comparison of the record contents strict. If a loose comparison is made (which is the default), comparing an empty string '' with the number 0 is not considered as an error ('' == 0), while using strict comparison it is ('' !== 0).

Make the comparison of record contents strict:

$GLOBALS['TYPO3_CONF_VARS']['BE']['checkStoredRecordsLoose'] = false;

Impact

In TYPO3 installations where the administrator has configured the database to run in strict-mode disabling the validation of stored records can speed-up inserts and updates by a factor of 2. With strict-mode enabled the record will not be saved at all, if there are errors.

If the validation of stored records is disabled, the entry in the protocol (sys_log) does not contain the record title (it is displayed as "[No title]" instead) - however table and uid are still provided and can be used for finding the record.

Affected Installations

None as default.
