From c72f78215bb3435ee2bbb507746c23eccec4dd34 Mon Sep 17 00:00:00 2001 From: Melanie Date: Wed, 4 Nov 2009 01:56:19 +0000 Subject: Backport the fixes to WebFetchInventoryDescendents to the UDP InventoryDescendents packet. Testing has shown that UDP inventory now works flawlessly and, unlike CAPS inventory, doesn't download the entire agent inventory on start. Neither does it incessantly re-request folder NULL_KEY. Therefore, I have disabled CAPS inventory. --- .../Region/ClientStack/LindenUDP/LLClientView.cs | 246 ++++++++------------- .../Region/Examples/SimpleModule/MyNpcCharacter.cs | 1 + OpenSim/Region/Framework/Scenes/Scene.Inventory.cs | 8 +- .../Framework/Scenes/Scene.PacketHandlers.cs | 2 +- .../Server/IRCClientView.cs | 2 +- .../Region/OptionalModules/World/NPC/NPCAvatar.cs | 1 + 6 files changed, 105 insertions(+), 155 deletions(-) (limited to 'OpenSim/Region') diff --git a/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs b/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs index db0c3b8..bd5df19 100644 --- a/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs +++ b/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs @@ -1251,7 +1251,7 @@ namespace OpenSim.Region.ClientStack.LindenUDP /// Do we need to send folder information? /// Do we need to send item information? public void SendInventoryFolderDetails(UUID ownerID, UUID folderID, List items, - List folders, + List folders, int version, bool fetchFolders, bool fetchItems) { // An inventory descendents packet consists of a single agent section and an inventory details @@ -1266,172 +1266,104 @@ namespace OpenSim.Region.ClientStack.LindenUDP // 6 to 7 items at a time, so let's stick with 6 int MAX_ITEMS_PER_PACKET = 6; - //Ckrinke This variable is not used, so comment out to remove the warning from the compiler (3-21-08) - //Ckrinke uint FULL_MASK_PERMISSIONS = 2147483647; - + int totalItems = fetchItems ? items.Count : 0; + int totalFolders = fetchFolders ? folders.Count : 0; int itemsSent = 0; - if (fetchItems) - { - InventoryDescendentsPacket descend = CreateInventoryDescendentsPacket(ownerID, folderID); - - if (items.Count < MAX_ITEMS_PER_PACKET) - { - descend.ItemData = new InventoryDescendentsPacket.ItemDataBlock[items.Count]; - } - else - { - descend.ItemData = new InventoryDescendentsPacket.ItemDataBlock[MAX_ITEMS_PER_PACKET]; - } + int foldersSent = 0; + int foldersToSend = 0; + int itemsToSend = 0; - // Descendents must contain the *total* number of descendents (plus folders, whether we - // fetch them or not), not the number of entries we send in this packet.
