8 * This file was at one time responsible for doing all deliveries, but this caused
9 * big problems on shared hosting systems, where the process might get killed by the
10 * hosting provider and nothing would get delivered.
11 * It now only delivers one message under certain cases, and invokes a queued
12 * delivery mechanism (include/deliver.php) to deliver individual contacts at
13 * controlled intervals.
14 * This has a much better chance of surviving random processes getting killed
15 * by the hosting provider.
16 * A lot of this code is duplicated in include/deliver.php until we have time to go back
17 * and re-structure the delivery procedure based on the obstacles that have been thrown at
18 * us by hosting providers.
22 * The notifier is typically called with:
24 * proc_run('php', "include/notifier.php", 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)
42 * and ITEM_ID is the id of the item in the database that needs to be sent to others.
