23 * Base class for queue handlers.
25 * As extensions of the Daemon class, each queue handler has the ability
26 * to launch itself in the background, at which point it'll pass control
27 * to the configured QueueManager class to poll for updates.
29 * Subclasses must override at least the following methods:
34 class DistribQueueHandler
37 * Return transport keyword which identifies items this queue handler
38 * services; must be defined for all subclasses.
40 * Must be 8 characters or less to fit in the queue_item database.
41 * ex "email", "jabber", "sms", "irc", ...
52 * Handle distribution of a notice after we've saved it:
53 * @li add to local recipient inboxes
54 * @li send email notifications to local @-reply targets
55 * @li run final EndNoticeSave plugin events
56 * @li put any remaining post-processing into the queues
58 * If this function indicates failure, a warning will be logged
59 * and the item is placed back in the queue to be re-run.
61 * @fixme addToInboxes is known to fail sometimes with large recipient sets
63 * @param Notice $notice
64 * @return boolean true on success, false on failure
