T is never constructed. +// - raise_lua_error itself: only va_list (ended before jump), string_view +// (trivially destructible) and lua_Debug (C struct) are on the stack. +// - Direct luaL_error calls in metamethods (__index, __newindex): no +// non-trivial C++ locals exist at the call site. +// - Property getters/setters receiving wrong self type: Userdata::get +// returns TypeResult — pointer type is trivially destructible. +// +// UNSAFE paths (potential UB + resource leak when Lua is compiled as C): +// - Multi-argument function invocation: invoke_callable_from_stack_impl() +// expands the argument pack via std::invoke(func, unwrap_arg(), ...). +// C++ does not guarantee evaluation order of function arguments. If T0 is +// decoded successfully into a non-trivially-destructible temporary and T1 +// fails, the T0 temporary's destructor is skipped by longjmp. +// - make_arguments_list_impl / tupleize: same expansion pattern suffers the +// same problem — std::tuple(arg0, arg1, ...) does not sequence the +// argument evaluations, so earlier successful args can be leaked on longjmp. +// - Constructor placement proxy / constructor_forwarder: after a successful +// make_arguments_list() the resulting tuple (potentially containing strings +// etc.) sits as a local variable. A subsequent raise_lua_error (e.g. when +// UserdataValue::place() fails) longjmps over it without calling destructors. +// +// These issues produce memory leaks (not crashes or corruption) in practice +// because the leaked objects are value copies materialized from Lua strings. +// SSO strings (typically ≤15 chars) involve no heap allocation and are +// effectively harmless; heap-allocated (longer) strings do leak their buffers. +// +// How to detect: +// Run the test suite under AddressSanitizer with LeakSanitizer enabled. +// The TrackedString type below provides a live-instance counter so that tests +// can assert whether destructors were called after a pcall error. + +#include "TestBase.h" + +#include +#include + +namespace { + +// --------------------------------------------------------------------------- +// TrackedString — a string wrapper with a live-instance counter. +// Constructing one increments the counter; destroying one decrements it. +// --------------------------------------------------------------------------- +std::atomic g_tracked_string_count{0}; + +struct TrackedString +{ + std::string value; + + TrackedString() + : value() + { + ++g_tracked_string_count; + } + + explicit TrackedString(std::string v) + : value(std::move(v)) + { + ++g_tracked_string_count; + } + + TrackedString(const TrackedString& o) + : value(o.value) + { + ++g_tracked_string_count; + } + + TrackedString(TrackedString&& o) noexcept + : value(std::move(o.value)) + { + ++g_tracked_string_count; + } + + ~TrackedString() + { + --g_tracked_string_count; + } + + TrackedString& operator=(const TrackedString& o) + { + value = o.value; + return *this; + } + + TrackedString& operator=(TrackedString&& o) noexcept + { + value = std::move(o.value); + return *this; + } +}; + +// A long string guaranteed to exceed the small-string optimisation threshold +// on all common implementations (SSO is typically ≤15 chars on GCC/Clang/MSVC). +constexpr const char* kLongString = "this string is definitely longer than sso threshold on all platforms"; + +} // namespace + +// Register Stack so LuaBridge can push/get it. +namespace luabridge { + +template <> +struct Stack +{ + [[nodiscard]] static Result push(lua_State* L, const TrackedString& v) + { + return Stack::push(L, v.value); + } + + [[nodiscard]] static TypeResult get(lua_State* L, int index) + { + auto result = Stack::get(L, index); + if (!result) + return result.error(); + + return TrackedString{std::move(*result)}; + } + + [[nodiscard]] static bool isInstance(lua_State* L, int index) + { + return Stack::isInstance(L, index); + } +}; + +} // namespace luabridge + +// --------------------------------------------------------------------------- +// Test fixture +// --------------------------------------------------------------------------- +struct LongjmpSafetyTests : TestBase +{ + void SetUp() override + { + TestBase::SetUp(); + g_tracked_string_count = 0; + } + + // Helper: verify that the live TrackedString count returned to zero after + // a pcall error.
