From eb5bec96e49466ede4ece376cb15cd68477ce983 Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Tue, 25 Sep 2012 22:54:20 +0100 Subject: Insert transaction ID into AssetXferUploader constructor rather than at UploadAsset() to prevent item creation failure when NewInventoryItem thread reachs the object first. This was preventing the previous race condition fix in 4fc0cfb from actually working. This commit also removes some of the pointless transaction id checks - these conditions are already being enforced in AgentAssetsTransactions. --- .../AssetTransaction/AgentAssetsTransactions.cs | 8 +-- .../Agent/AssetTransaction/AssetXferUploader.cs | 77 +++++++++++++--------- 2 files changed, 49 insertions(+), 36 deletions(-) (limited to 'OpenSim/Region/CoreModules/Agent/AssetTransaction') diff --git a/OpenSim/Region/CoreModules/Agent/AssetTransaction/AgentAssetsTransactions.cs b/OpenSim/Region/CoreModules/Agent/AssetTransaction/AgentAssetsTransactions.cs index 59d0075..0271738 100644 --- a/OpenSim/Region/CoreModules/Agent/AssetTransaction/AgentAssetsTransactions.cs +++ b/OpenSim/Region/CoreModules/Agent/AssetTransaction/AgentAssetsTransactions.cs @@ -73,7 +73,7 @@ namespace OpenSim.Region.CoreModules.Agent.AssetTransaction { if (!XferUploaders.ContainsKey(transactionID)) { - uploader = new AssetXferUploader(this, m_Scene, m_dumpAssetsToFile);
