|
|
This module handles adding/removing friends, and the the presence
|
|
notification process for login/logoff of friends.
|
|
|
|
The presence notification works as follows:
|
|
- After the user initially connects to a region (so we now have a UDP
|
|
connection to work with), this module fetches the friends of user
|
|
(those are cached), their on-/offline status, and info about the
|
|
region they are in from the MessageServer.
|
|
- (*) It then informs the user about the on-/offline status of her friends.
|
|
- It then informs all online friends currently on this region-server about
|
|
user's new online status (this will save some network traffic, as local
|
|
messages don't have to be transferred inter-region, and it will be all
|
|
that has to be done in Standalone Mode).
|
|
- For the rest of the online friends (those not on this region-server),
|
|
this module uses the provided region-information to map users to
|
|
regions, and sends one notification to every region containing the
|
|
friends to inform on that server.
|
|
- The region-server will handle that in the following way:
|
|
- If it finds the friend, it informs her about the user being online.
|
|
- If it doesn't find the friend (maybe she TPed away in the meantime),
|
|
it stores that information.
|
|
- After it processed all friends, it returns the list of friends it
|
|
couldn't find.
|
|
- If this list isn't empty, the FriendsModule re-requests information
|
|
about those online friends that have been missed and starts at (*)
|
|
again until all friends have been found, or until it tried 3 times
|
|
(to prevent endless loops due to some uncaught error).
|
|
|
|
NOTE: Online/Offline notifications don't need to be sent on region change.
|
|
|
|
We implement two XMLRpc handlers here, handling all the inter-region things
|
|
we have to handle:
|
|
- On-/Offline-Notifications (bulk)
|
|
- Terminate Friendship messages (single)
