## What's Changed ### General - Allow types of tables to diverge after using `table.clone` (fixes #1617). - Allow 2-argument vector.create in Luau. - Fix a crash when suggesting autocomplete after encountering parsing errors. - Add lua_tolstringatom C API which returns the string length (whether or not the atom exists) and which extends the existing lua_tostringatom function the same way lua_tolstring/lua_tostring do. - Luau now retains the DFGs of typechecked modules. ### Magic Functions Migration Note We've made a change to the API used to define magic functions. Previously, we had a set of function pointers on each `FunctionType` that would be invoked by the type inference engine at the correct point. The problem we'd run into is that they were all `std::function`s, we'd grown quite a few of them, and Luau allocates tens of thousands of types as it performs type inference. This adds up to a large amount of memory for data that isn't used by 99% of types. To slim things down a bit, we've replaced all of those `std::function`s with a single `shared_ptr` to a new interface called `MagicFunction`. This slims down the memory footprint of each type by about 50 bytes. The virtual methods of `MagicFunction` have roughly 1:1 correspondence with the old interface, so updating things should not be too difficult: * `FunctionType::magicFunction` is now `MagicFunction::handleOldSolver` * `FunctionType::dcrMagicFunction` is now `MagicFunction::infer` * `FunctionType::dcrMagicRefinement` is now `MagicFunction::refine` * `FunctionType::dcrMagicTypeCheck` is now `MagicFunction::typeCheck` **Full Changelog**: https://github.com/luau-lang/luau/compare/0.657...0.658 --- Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Ariel Weiss <aaronweiss@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Talha Pathan <tpathan@roblox.com> Co-authored-by: Varun Saini <vsaini@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> |
