From 423f49d175d8db6283232bd8bdc106e26bdcff4d Mon Sep 17 00:00:00 2001 From: "madmaxoft@gmail.com" Date: Thu, 16 Feb 2012 13:42:35 +0000 Subject: Chunk is now marked as dirty; saving only dirty chunks; rewritten load / save not to use cChunkPtr; set VC2008 project to level4 warnings; block entities are now loaded and saved properly git-svn-id: http://mc-server.googlecode.com/svn/trunk@273 0a769ca7-a7f5-676a-18bf-c427514a06d6 --- VC2008/MCServer.vcproj | 12 ++- VC2010/MCServer.vcxproj | 2 + VC2010/MCServer.vcxproj.filters | 2 + WebServer/Globals.h | 23 +++++ makefile_base | 7 +- source/Globals.h | 20 ++++- source/StringCompression.cpp | 54 ++++++++++++ source/StringCompression.h | 17 ++++ source/WSSCompact.cpp | 189 +++++++++++++++++++++++++++++----------- source/WSSCompact.h | 17 ++-- source/WorldStorage.cpp | 181 ++++++++++++++++++++++++++++---------- source/WorldStorage.h | 76 +++++++++++++--- source/cBlockEntity.h | 7 ++ source/cChestEntity.cpp | 5 -- source/cChestEntity.h | 4 +- source/cChunk.cpp | 153 ++++++++++++++++++++++++++++++-- source/cChunk.h | 52 ++++++++++- source/cChunk.inl.h | 39 +++++++++ source/cChunkMap.cpp | 111 +++++++++++++++++++++-- source/cChunkMap.h | 12 ++- source/cCriticalSection.h | 6 ++ source/cFurnaceEntity.h | 2 +- source/cPlayer.cpp | 2 +- source/cSignEntity.h | 4 +- source/cWindow.cpp | 45 ++++++++-- source/cWorld.cpp | 73 +++++++++++++++- source/cWorld.h | 14 ++- source/main.cpp | 6 +- 28 files changed, 979 insertions(+), 156 deletions(-) create mode 100644 source/StringCompression.cpp create mode 100644 source/StringCompression.h diff --git a/VC2008/MCServer.vcproj b/VC2008/MCServer.vcproj index 198ddb3d6..504ffc9ae 100644 --- a/VC2008/MCServer.vcproj +++ b/VC2008/MCServer.vcproj @@ -48,7 +48,7 @@ RuntimeLibrary="3" UsePrecompiledHeader="2" PrecompiledHeaderThrough="Globals.h" - WarningLevel="3" + WarningLevel="4" DebugInformationFormat="4" /> + + + + diff --git a/VC2010/MCServer.vcxproj b/VC2010/MCServer.vcxproj index 81de6d3d5..620e3fb54 100644 --- a/VC2010/MCServer.vcxproj +++ b/VC2010/MCServer.vcxproj @@ -476,6 +476,7 @@ NotUsing NotUsing + @@ -651,6 +652,7 @@ + diff --git a/VC2010/MCServer.vcxproj.filters b/VC2010/MCServer.vcxproj.filters index 223342bb4..5aa4a95a0 100644 --- a/VC2010/MCServer.vcxproj.filters +++ b/VC2010/MCServer.vcxproj.filters @@ -910,6 +910,7 @@ + @@ -1404,6 +1405,7 @@ + diff --git a/WebServer/Globals.h b/WebServer/Globals.h index 405de1075..389654d33 100644 --- a/WebServer/Globals.h +++ b/WebServer/Globals.h @@ -8,6 +8,29 @@ +// Compiler-dependent stuff: +#ifndef _MSC_VER + // Non-MS compilers don't know the override keyword + #define override +#else + // MSVC produces warning C4481 on the override keyword usage, so disable the warning altogether + #pragma warning(disable:4481) +#endif // _MSC_VER + + + + + +// A macro to disallow the copy constructor and operator= functions +// This should be used in the private: declarations for any class that shouldn't allow copying itself +#define DISALLOW_COPY_AND_ASSIGN(TypeName) \ + TypeName(const TypeName &);
