protected function shouldThrottle($name, $duration)
Inherited

PhutilDaemonOverseerModule

Throttle checks from executing too often.

If you throttle a check like this, it will only execute once every 2.5 seconds:

if ($this->shouldThrottle('some.check', 2.5)) {
  return;
}
Parameters
string$nameThrottle key.
float$durationDuration in seconds.
Return
boolTrue to throttle the check.

private function loadConfigVersion()

Calculate a version number for the current Phabricator configuration.

Check and update the configuration version.

Return
boolTrue if the daemons should restart, otherwise false.
