From a939e2ded97730b7847593dab2b9abb849bd6555 Mon Sep 17 00:00:00 2001 From: Mattes D Date: Sun, 8 Feb 2015 12:24:15 +0100 Subject: WSSAnvil: Fixed chunk data padding. When the chunk data fit perfectly into the old space, an extra 4 KiB of padding zeroes were written, overwriting the next chunk. Fixes #1730. --- src/WorldStorage/WSSAnvil.cpp | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/WorldStorage/WSSAnvil.cpp b/src/WorldStorage/WSSAnvil.cpp index a76e9461a..ae82db346 100755 --- a/src/WorldStorage/WSSAnvil.cpp +++ b/src/WorldStorage/WSSAnvil.cpp @@ -3136,8 +3136,11 @@ bool cWSSAnvil::cMCAFile::SetChunkData(const cChunkCoords & a_Chunk, const AStri // Add padding to 4K boundary: size_t BytesWritten = a_Data.size() + MCA_CHUNK_HEADER_LENGTH; - static const char Padding[4095] = {0}; - m_File.Write(Padding, 4096 - (BytesWritten % 4096)); + if (BytesWritten % 4096 != 0) + { + static const char Padding[4095] = {0}; + m_File.Write(Padding, 4096 - (BytesWritten % 4096)); + } // Store the header: ChunkSize = ((u_long)a_Data.size() + MCA_CHUNK_HEADER_LENGTH + 4095) / 4096; // Round data size *up* to nearest 4KB sector, make it a sector number -- cgit v1.2.3
