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/llfilesystem/lldir_linux.cpp | 269 +++++++++++++++++++++++++++++++++++++ 1 file changed, 269 insertions(+) create mode 100644 indra/llfilesystem/lldir_linux.cpp (limited to 'indra/llfilesystem/lldir_linux.cpp') diff --git a/indra/llfilesystem/lldir_linux.cpp b/indra/llfilesystem/lldir_linux.cpp new file mode 100644 index 0000000000..80ad05345a --- /dev/null +++ b/indra/llfilesystem/lldir_linux.cpp @@ -0,0 +1,269 @@ +/** + * @file lldir_linux.cpp + * @brief Implementation of directory utilities for linux + * + * $LicenseInfo:firstyear=2002&license=viewerlgpl$ + * 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.
