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.

Running

cmake --build build --target test
cd build && RUNS=100000 ctest -R luaL_gsub_test --verbose
