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
Vighnesh-V	2e6fdd90a0	Sync to upstream/release/655 (#1563) ... ## New Solver * Type functions should be able to signal whether or not irreducibility is due to an error * Do not generate extra expansion constraint for uninvoked user-defined type functions * Print in a user-defined type function reports as an error instead of logging to stdout * Many e-graphs bugfixes and performance improvements * Many general bugfixes and improvements to the new solver as a whole * Fixed issue with used-defined type functions not being able to call each other * Infer types of globals under new type solver ## Fragment Autocomplete * Miscellaneous fixes to make interop with the old solver better ## Runtime * Support disabling specific built-in functions from being fast-called or constant-evaluated (Closes #1538) * New compiler option `disabledBuiltins` accepts a list of library function names like "tonumber" or "math.cos" * Added constant folding for vector arithmetic * Added constant propagation and type inference for vector globals (Fixes #1511) * New compiler option `librariesWithKnownMembers` accepts a list of libraries for members of which a request for constant value and/or type will be made * `libraryMemberTypeCb` callback is called to get the type of a global, return one of the `LuauBytecodeType` values. 'boolean', 'number', 'string' and 'vector' type are supported. * `libraryMemberConstantCb` callback is called to setup the constant value of a global. To set a value, C API `luau_set_compile_constant_*` or C++ API `setCompileConstant*` functions should be used. --- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Daniel Angel <danielangel@roblox.com> Co-authored-by: Jonathan Kelaty <jkelaty@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@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> --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Junseo Yoo <jyoo@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Co-authored-by: Alexander Youngblood <ayoungblood@roblox.com> Co-authored-by: Varun Saini <vsaini@roblox.com> Co-authored-by: Andrew Miranti <amiranti@roblox.com> Co-authored-by: Shiqi Ai <sai@roblox.com> Co-authored-by: Yohoo Lin <yohoo@roblox.com> Co-authored-by: Daniel Angel <danielangel@roblox.com> Co-authored-by: Jonathan Kelaty <jkelaty@roblox.com>	2024-12-13 13:02:30 -08:00
Hunter Goldstein	a36a3c41cc	Sync to upstream/release/651 (#1513) ... ### What's New? * Fragment Autocomplete: a new API allows for type checking a small fragment of code against an existing file, significantly speeding up autocomplete performance in large files. ### New Solver * E-Graphs have landed: this is an ongoing approach to make the new type solver simplify types in a more consistent and principled manner, based on similar work (see: https://egraphs-good.github.io/). * Adds support for exporting / local user type functions (previously they were always exported). * Fixes a set of bugs in which the new solver will fail to complete inference for simple expressions with just literals and operators. ### General Updates * Requiring a path with a ".lua" or ".luau" extension will now have a bespoke error suggesting to remove said extension. * Fixes a bug in which whether two `Luau::Symbol`s are equal depends on whether the new solver is enabled. --- Internal Contributors: Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@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>	2024-11-08 13:41:45 -08:00
