ayoungbloodrbx	c13b5b7440	Sync to upstream/release/658 (#1625) ... ## 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>	2025-01-24 12:15:19 -08:00
Andy Friesen	0b2755f964	Sync to upstream/release/589 (#1000) ... * Progress toward a diffing algorithm for types. We hope that this will be useful for writing clearer error messages. * Add a missing recursion limiter in `Unifier::tryUnifyTables`. This was causing a crash in certain situations. * Luau heap graph enumeration improvements: * Weak references are not reported * Added tag as a fallback name of non-string table links * Included top Luau function information in thread name to understand where thread might be suspended * Constant folding for `math.pi` and `math.huge` at -O2 * Optimize `string.format` and `%*` * This change makes string interpolation 1.5x-2x faster depending on the number and type of formatted components, assuming a few are using primitive types, and reduces associated GC pressure. New type checker: * Initial work toward tracking the upper and lower bounds of types accurately. Native code generation (JIT): * Add IrCmd::CHECK_TRUTHY for improved assert fast-calls * Do not compute type map for modules without types * Capture metatable+readonly state for NEW_TABLE IR instructions * Replace JUMP_CMP_ANY with CMP_ANY and existing JUMP_EQ_INT * Add support for exits to VM with reentry lock in VmExit --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>	2023-08-04 12:18:54 -07:00
