public function DrupalPhaseControl::checkNewExtensions in X Autoload 7.5

Checks if new extensions have been enabled, and registers them.

This is called from xautoload_module_implements_alter(), which is called whenever a new module is enabled, but also some calls we need to ignore.

File

src/Phases/DrupalPhaseControl.php, line 128

Code

public function checkNewExtensions() {
  if (!$this->awake) {

    // The entire thing is not initialized yet.
    // Postpone until operateOnFinder()
    return;
  }
  $activeExtensions = $this->system
    ->getActiveExtensions();
  if ($activeExtensions === $this->extensions) {

    // Nothing actually changed. False alarm.
    return;
  }

  // Now check all extensions to find out if any of them is new.
  foreach ($activeExtensions as $name => $type) {
    if (!isset($this->extensions[$name])) {

      // This extension was freshly enabled.
      if ('xautoload' === $name) {

        // If xautoload is enabled in this request, then boot phase and main
        // phase are not properly initialized yet.
        $this
          ->enterMainPhase();
      }

      // Notify observers about the new extension.
      foreach ($this->observers as $observer) {
        $observer
          ->welcomeNewExtension($name, $type);
      }
    }
