Post WP3.1 PHP 5 register_shutdown_function() note - Remove Backwards compability
|Reported by:||hakre||Owned by:|
In some classes (DB, Cache) register_shutdown_function() is used to mimic destruct() in PHP 4 so it looks appropriate to remove that when wordpress codebase becomes PHP 5.2+.
But in fact the register_shutdown_function() probably must be kept for backwards compatibility, bećause desctruct() is not called in PHP 5.2+ in all cases in which register_shutdown_function() registered functions are called.
So to remove the shutdown hook will break backwards compatibility because it is buggy for a mimic of destruct().
I suggest to remove this buggy implementation and break with backwards compatibility.
