The way forward for push notifications? You are probably looking for mod_cloud_notify for now though

Option Default Description
contact_uri xmpp:server.tld Contact information for the server operator (usually as a mailto: URI is preferred)
push_max_hibernation_timeout 259200 (72h) Number of seconds to extend the smacks timeout if no push was triggered yet (default: 72 hours)

Internal design notes

App servers are notified about offline messages, messages stored by mod_mam or messages waiting in the smacks queue.

To cooperate with mod_smacks this module consumes some events: smacks-ack-delayed, smacks-hibernation-start and smacks-hibernation-end. These events allow this module to send out notifications for messages received while the session is hibernated by mod_smacks or even when smacks acknowledgements for messages are delayed by a certain amount of seconds configurable with the mod_smacks setting smacks_max_ack_delay.

The smacks_max_ack_delay setting allows to send out notifications to clients which aren’t already in smacks hibernation state (because the read timeout or connection close didn’t already happen) but also aren’t responding to acknowledgement request in a timely manner. This setting thus allows conversations to be smoother under such circumstances.


Note: This module should be used with Lua 5.3 and higher.

Requires a slightly patches luaossl right now:

trunk Works
