From 3fc07dea01795b31c37dcd093ec73d190a1e188a Mon Sep 17 00:00:00 2001 From: Callum Prentice Date: Wed, 16 Sep 2020 18:53:24 -0700 Subject: First part of change to remove LLVFS from the Viewer. Consists of code changes to remove LLVFS and LLVFSThread classes along with the associated source files. The existing llvfs folder is renamed to llcache. Also includes changes to CMake script in many places to reflect changes. Eventually, llvfile source file and class will be renamed but that is not in this change. --- indra/llvfs/lldiriterator.cpp | 243 ------------------------------------------ 1 file changed, 243 deletions(-) delete mode 100644 indra/llvfs/lldiriterator.cpp (limited to 'indra/llvfs/lldiriterator.cpp') diff --git a/indra/llvfs/lldiriterator.cpp b/indra/llvfs/lldiriterator.cpp deleted file mode 100644 index 3eb64e69d9..0000000000 --- a/indra/llvfs/lldiriterator.cpp +++ /dev/null @@ -1,243 +0,0 @@ -/** - * @file lldiriterator.cpp - * @brief Iterator through directory entries matching the search pattern. - * - * $LicenseInfo:firstyear=2010&license=viewerlgpl$ - * Second Life Viewer Source Code - * Copyright (C) 2010, Linden Research, Inc. - * - * This library is free software; you can redistribute it and/or - * modify it under the terms of the GNU Lesser General Public - * License as published by the Free Software Foundation; - * version 2.1 of the License only. - * - * This library is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
