MOODLE_20_STABLE
While working on format_text() performance, I realized there is a bug in
if (!empty($CFG->perfdebug)) {
|
self::$singletoninstance = new performance_measuring_filter_manager();
|
} else {
|
self::$singletoninstance = new self();
|
}
|
$CFG->perfdebug uses values 7 (unchecked) and 15 (checked) since very early commits back in 2005 - and therefore Moodle 2.0 always instantinates performance_measuring_filter_manager() even if it does not need to.
The values used by $CFG->perfdebug are confusing and may lead easily to other bugs like this one. I suggest to update $CFG->perfdebug to simple 0/1 switcher.
