From 8638766d791a5711b445a257f515671137a013cf Mon Sep 17 00:00:00 2001 From: "Justin Clark-Casey (justincc)" Date: Fri, 2 Nov 2012 01:41:38 +0000 Subject: [PATCH] Add [AssetService] AllowRemoteDeleteAllTypes (default false). This allows a closed grid to delete asset types other than maptile remotely. Only operational if AllowRemoteDelete = true also. Defaults to false - do not enable if anybody other than you can make asset service requests. --- .../Handlers/Asset/AssetServerConnector.cs | 17 ++++++- .../Asset/AssetServerDeleteHandler.cs | 50 +++++++++++++------ bin/Robust.ini.example | 14 +++++- 3 files changed, 65 insertions(+), 16 deletions(-) diff --git a/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs b/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs index 8b9e749aa4..0f2ece7573 100644 --- a/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs +++ b/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs @@ -67,10 +67,25 @@ namespace OpenSim.Server.Handlers.Asset throw new Exception(String.Format("Failed to load AssetService from {0};
