this is step 2 of 2 of the OpenSim.Region.Environment refactor.
NOTHING has been deleted or moved off to forge at this point. what
has happened is that OpenSim.Region.Environment.Modules has been split
in two:
- OpenSim.Region.CoreModules: all those modules that are either
directly or indirectly referenced from other OpenSim packages, or
that provide functionality that the OpenSim developer community
considers core functionality:
CoreModules/Agent/AssetTransaction
CoreModules/Agent/Capabilities
CoreModules/Agent/TextureDownload
CoreModules/Agent/TextureSender
CoreModules/Agent/TextureSender/Tests
CoreModules/Agent/Xfer
CoreModules/Avatar/AvatarFactory
CoreModules/Avatar/Chat/ChatModule
CoreModules/Avatar/Combat
CoreModules/Avatar/Currency/SampleMoney
CoreModules/Avatar/Dialog
CoreModules/Avatar/Friends
CoreModules/Avatar/Gestures
CoreModules/Avatar/Groups
CoreModules/Avatar/InstantMessage
CoreModules/Avatar/Inventory

CoreModules/Avatar/Inventory/Transfer
CoreModules/Avatar/Lure
CoreModules/Avatar/ObjectCaps
CoreModules/Avatar/Profiles
CoreModules/Communications/Local
CoreModules/Communications/REST
CoreModules/Framework/EventQueue
CoreModules/Framework/InterfaceCommander
CoreModules/Hypergrid
CoreModules/InterGrid
CoreModules/Scripting/DynamicTexture
CoreModules/Scripting/EMailModules
CoreModules/Scripting/HttpRequest
CoreModules/Scripting/LoadImageURL
CoreModules/Scripting/VectorRender
CoreModules/Scripting/WorldComm
CoreModules/Scripting/XMLRPC

- OpenSim.Region.OptionalModules: all those modules that are not core
modules:
OptionalModules/Avatar/Chat/IRC-stuff

45 | This module handles adding/removing friends, and the the presence | ||
46 | notification process for login/logoff of friends. | ||
47 | |||
48 | The presence notification works as follows: | ||
49 | - After the user initially connects to a region (so we now have a UDP | ||
50 | connection to work with), this module fetches the friends of user | ||
51 | (those are cached), their on-/offline status, and info about the | ||
52 | region they are in from the MessageServer. | ||
53 | - (*) It then informs the user about the on-/offline status of her friends. | ||
54 | - It then informs all online friends currently on this region-server about | ||
55 | user's new online status (this will save some network traffic, as local | ||
56 | messages don't have to be transferred inter-region, and it will be all | ||
57 | that has to be done in Standalone Mode). | ||
58 | - For the rest of the online friends (those not on this region-server), | ||
59 | this module uses the provided region-information to map users to | ||
60 | regions, and sends one notification to every region containing the | ||
61 | friends to inform on that server. | ||
62 | - The region-server will handle that in the following way: | ||
63 | - If it finds the friend, it informs her about the user being online. | ||
64 | - If it doesn't find the friend (maybe she TPed away in the meantime), | ||
65 | it stores that information. | ||
66 | - After it processed all friends, it returns the list of friends it | ||
67 | couldn't find. | ||
68 | - If this list isn't empty, the FriendsModule re-requests information | ||
69 | about those online friends that have been missed and starts at (*) | ||
70 | again until all friends have been found, or until it tried 3 times | ||
71 | (to prevent endless loops due to some uncaught error). | ||
72 | |||
73 | NOTE: Online/Offline notifications don't need to be sent on region change. | ||
74 | |||
75 | We implement two XMLRpc handlers here, handling all the inter-region things | ||
76 | we have to handle: | ||
77 | - On-/Offline-Notifications (bulk) | ||
78 | - Terminate Friendship messages (single) | ||
