From 168d177197bd7558bbe0ca13d01c984ad8638da7 Mon Sep 17 00:00:00 2001 From: Callum Prentice Date: Tue, 9 Mar 2021 14:39:51 -0800 Subject: This set of changes reverts the merge with master (git revert c83e740) and results in a version of the DRTVWR-519 that matches what was presemt before it was deployed as a release viewer *plus* 3 small fixes from Maxim (See commits). This branch can now be used for additional fixes before eventually being used to release D-519 as normal --- 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.
