Resources

Data used for testing and understanding the internals of Minecraft/FOSS-VG, also contains code to produce such data

java/

Programs to produce data for figuring out how to interact with Java-specific things

• JavaStringGenerator.java: A simple tool that reads from stdin and outputs Java-style UTF-8 to stdout
• netty-tests/: Figure out how Netty operates

NBT_data/

Data used to test the NBT library

bare_int64_tag: What the name says bare_int64_tag_and_int32_tag: What the name says simple_nbt: A simple NBT file containing all tag types nested_compounds_and_lists: A combination of nested compound and list tags (parser stress test) servers.dat: Pulled from my Minecraft installation servers.dat_nbt_decoded.txt: The same data manually decoded (This was done to get a better understanding how NBT works, might come in handy.) level.dat: Pulled from one of my world saves (gzip-compressed) level.dat_decompressed: The same data decompressed

network_capture/

Network captures used to get an understanding of the protocol

ping.pcapng: WireShark capture of the multipayer screen server ping ping_decoded.txt: Extracted TCP payloads from the network capture annotated with what’s happening

unicode_data/

Files with unicode data

• Bare ("normal") UTF-8
• Java format

all_bytes

Every possible 8-bit byte in ascending order

check_endianness.cpp

A simple tool to determine the endianness of the system and write the endianness header for FOSS-VG

Supports: Little Endian, Big Endian, PDP Endian, Honeywell Endian

Usage: check_endianness > header_file

Note that, while this tool should in theory be able to detect PDP and Honeywell-316-style endianness, the FOSS-VG project itself does not support these.

region_files

Exactly what the name says. At this point just a random region file I grabbed from Minecraft, will probably contain synthetic files for test cases in the future as well.
