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