Breaking: #88498 - Global data for TimeTracker statistics removed

See forge#88498

Description

The TimeTracker used some global variables to store microtime() when a Frontend request was started and ended, as information for the Admin Panel and as HTTP Header, if debug mode is enabled for Frontend.

This information is now encapsulated within the TimeTracker object, making the following global variables obsolete:

  • $GLOBALS['TYPO3_MISC']['microtime_start']
  • $GLOBALS['TYPO3_MISC']['microtime_end']
  • $GLOBALS['TYPO3_MISC']['microtime_BE_USER_start']
  • $GLOBALS['TYPO3_MISC']['microtime_BE_USER_end']

This also results in having $GLOBALS['TYPO3_MISC'] to not be set anymore.

Impact

Accessing the global variables will trigger a PHP E_WARNING error, as they do not exist anymore.

Affected Installations

Any TYPO3 installation with an extension working with any of the global variables.

Migration

Remove the usages and either use the newly introduced TimeTracker->finish() to calculate data, or set your own variables, if microtime is needed.
