From: Loic Blot Date: Sat, 11 Apr 2020 09:22:15 +0000 (+0200) Subject: Drop content_sao.{cpp,h} X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5146086a64d5eeb480948d612a008a2ec81455d4;p=oweals%2Fminetest.git Drop content_sao.{cpp,h} Move LuaEntitySAO to a new dedicated file Drop TestSAO (useless object) Drop the old static startup initialized SAO factory, which was pretty useless. This factory was using a std::map for 2 elements, now just use a simple condition owned by ServerEnvironment, which will be lightweight, that will also drop a one time useful test on each LuaEntitySAO creation. This should reduce server load on massive SAO creation --- diff --git a/build/android/jni/Android.mk b/build/android/jni/Android.mk index 32a16c174..fdbfba9bc 100644 --- a/build/android/jni/Android.mk +++ b/build/android/jni/Android.mk @@ -161,7 +161,6 @@ LOCAL_SRC_FILES := \ jni/src/content/mods.cpp \ jni/src/content_nodemeta.cpp \ jni/src/content/packages.cpp \ - jni/src/content_sao.cpp \ jni/src/content/subgames.cpp \ jni/src/convert_json.cpp \ jni/src/craftdef.cpp \ @@ -258,8 +257,11 @@ LOCAL_SRC_FILES := \ jni/src/server.cpp \ jni/src/serverenvironment.cpp \ jni/src/serverlist.cpp \ + jni/src/server/luaentity_sao.cpp \ jni/src/server/mods.cpp \ + jni/src/server/player_sao.cpp \ jni/src/server/serveractiveobject.cpp \ + jni/src/server/unit_sao.cpp \ jni/src/settings.cpp \ jni/src/staticobject.cpp \ jni/src/tileanimation.cpp \ diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index faa117d41..0ebbd628c 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -375,7 +375,6 @@ set(common_SRCS collision.cpp content_mapnode.cpp content_nodemeta.cpp - content_sao.cpp convert_json.cpp craftdef.cpp debug.cpp diff --git a/src/clientiface.cpp b/src/clientiface.cpp index 17237f73e..4f954342a 100644 --- a/src/clientiface.cpp +++ b/src/clientiface.cpp @@ -19,7 +19,6 @@ with this program; if not, write to the Free Software Foundation, Inc., #include #include "clientiface.h" -#include "content_sao.h" #include "network/connection.h" #include "network/serveropcodes.h" #include "remoteplayer.h" @@ -28,6 +27,7 @@ with this program; if not, write to the Free Software Foundation, Inc., #include "serverenvironment.h" #include "map.h" #include "emerge.h" +#include "server/luaentity_sao.h" #include "server/player_sao.h" #include "log.h" #include "util/srp.h" diff --git a/src/content_sao.cpp b/src/content_sao.cpp deleted file mode 100644 index 7ec17aa82..000000000 --- a/src/content_sao.cpp +++ /dev/null @@ -1,681 +0,0 @@ -/* -Minetest -Copyright (C) 2010-2013 celeron55, Perttu Ahola - -This program 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; either version 2.1 of the License, or -(at your option) any later version. - -This program 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.
