PUC Rio Lua
LuaJIT

Lua C API tests

is a set of fuzzing tests for C implementations of Lua runtime (PUC Rio Lua and LuaJIT).

Building

git clone --jobs $(nproc) --recursive https://github.com/ligurio/lua-c-api-tests
CC=clang CXX=clang++ cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug -DUSE_LUA=ON [-DUSE_LUAJIT=ON]
cmake --build build --parallel

CMake options:

• USE_LUA enables building PUC Rio Lua.
• USE_LUAJIT enables building LuaJIT.
• LUA_VERSION could be a Git branch, tag or commit. By default LUA_VERSION is master for PUC Rio Lua and v2.1 for LuaJIT.
• ENABLE_LUAJIT_RANDOM_RA enables randomness in a register allocation. Option is LuaJIT-specific.
• ENABLE_ASAN enables AddressSanitizer.
• ENABLE_UBSAN enables UndefinedBehaviorSanitizer.
• ENABLE_COV enables coverage instrumentation.
• ENABLE_LUA_ASSERT enables all assertions inside Lua source code.
• ENABLE_LUA_APICHECK enables consistency checks on the C API.
• OSS_FUZZ enables support of OSS Fuzz.
• ENABLE_BUILD_PROTOBUF enables building Protobuf library, otherwise system library is used.
• ENABLE_INTERNAL_TESTS enables internal tests.
