16 * This file was at one time responsible for doing all deliveries, but this caused
17 * big problems when the process was killed or stalled during the delivery process.
18 * It now invokes separate queues that are delivering via delivery.php and pubsubpublish.php.
22 * The notifier is typically called with:
24 * Worker::add(PRIORITY_HIGH, "notifier", COMMAND, ITEM_ID);
26 * where COMMAND is one of the following:
28 * activity (in diaspora.php, dfrn_confirm.php, profiles.php)
29 * comment-import (in diaspora.php, items.php)
30 * comment-new (in item.php)
31 * drop (in diaspora.php, items.php, photos.php)
32 * edit_post (in item.php)
33 * event (in events.php)
34 * expire (in items.php)
35 * like (in like.php, poke.php)
36 * mail (in message.php)
37 * suggest (in fsuggest.php)
38 * tag (in photos.php, poke.php, tagger.php)
39 * tgroup (in items.php)
40 * wall-new (in photos.php, item.php)
41 * removeme (in Contact.php)
42 * relocate (in uimport.php)
44 * and ITEM_ID is the id of the item in the database that needs to be sent to others.
