7 # Introduction |
|
8 |
|
9 This is an experimental fork of [mod_cloud_notify](https://modules.prosody.im/mod_cloud_notify.html) |
|
10 which allows a [XEP-0357 Push Notifications App Servers](https://xmpp.org/extensions/xep-0357.html#general-architecture) |
|
11 to be registered against a MUC domain (normally they're only registered against |
|
12 your own chat server's domain). |
|
13 |
|
14 The goal here is to also enable push notifications also for MUCs. |
|
15 |
|
16 In contrast to mod_cloud_notify, this module does NOT integrate with |
|
17 mod_smacks, because a MUC can't access a remote user's XEP-0198 queue. |
|
18 |
|
19 Configuration |
|
20 ============= |
|
21 |
|
22 Option Default Description |
|
23 ------------------------------------ ----------------- ------------------------------------------------------------------------------------------------------------------- |
|
24 `push_notification_with_body` `false` Whether or not to send the message body to remote pubsub node. |
|
25 `push_notification_with_sender` `false` Whether or not to send the message sender to remote pubsub node. |
|
26 `push_max_errors` `16` How much persistent push errors are tolerated before notifications for the identifier in question are disabled |
|
27 `push_notification_important_body` `New Message!` The body text to use when the stanza is important (see above), no message body is sent if this is empty |
|
28 `push_max_devices` `5` The number of allowed devices per user (the oldest devices are automatically removed if this threshold is reached) |
|
29 |
|
30 There are privacy implications for enabling these options because |
|
31 plaintext content and metadata will be shared with centralized servers |
|
32 (the pubsub node) run by arbitrary app developers. |
|
33 |
|
34 ## To test this module: |
|
35 |
|
36 The [Converse](http://conversejs.org/) client has support for registering push |
|
37 "app servers" against a MUC. |
|
38 |
|
39 You specify app servers with the [push_app_servers](https://github.com/conversejs/converse.js/blob/master/docs/source/configuration.rst#push_app_servers) |
|
40 config setting. |
|
41 |
|
42 And then you need to set [allow_muc_invitations](https://github.com/conversejs/converse.js/blob/master/docs/source/configuration.rst#allow_muc_invitations) |
|
43 to `true` so that these app servers are also registered against MUC domains. |
|
44 |
|
45 Then, when you enter a MUC, Converse will try to automatically registered the |
|
46 app servers against the MUC domain. |
|
47 |
|
48 Note: currently Converse currently doesn't let you register separate app servers for |
|
49 a MUC domain. The same app servers are registered for the MUC domain and your |
|
50 own domain. |
|
51 |
|
52 ## To be done: |
|
53 |
|
54 We currently don't handle "ghost connections", users who are currently offline |
|
55 but the XMPP server is not yet aware of this and shows considers them online in |
|
56 the MUC. |
|
57 |
|
58 Prosody already checks for error bounces from undelivered groupchat messages |
|
59 and then kicks the particular user from the room. |
|
60 |
|
61 So these ghost connection users eventually get kicked from the room. |
|
62 |
|
63 We now need a module that fires an event when a groupchat messages can't be |
|
64 delivered to an occupant. The module can look up the undelivered message in MAM |
|
65 and include it in the event. |
|
66 |
|
67 In mod_muc_cloud_notify we can then listen for this event and send out a push |
|
68 notification. |
