This is an implementation of the server bits of XEP-0357: Push Notifications. It allows clients to register an "app server" which is notified about new messages while the user is offline, disconnected or the session is hibernated by mod_smacks. Implementation of the "app server" is not included1.
App servers are notified about offline messages 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 happen already) but also aren't responding to acknowledgement request in a timely manner, thus allowing conversations to be smoother under such circumstances.
||Whether or not to send the message body to remote pubsub node.|
||Whether or not to send the message sender to remote pubsub node.|
There are privacy implications for enabling these options because plaintext content and metadata will be shared with centralized servers (the pubsub node) run by arbitrary app developers.
Same as any other module.
Configured in-band by supporting clients.
Should work with 0.9+.
