Sync to upstream/release/507-pre (luau-lang#286) This doesn't contain all changes for 507 yet but we might want to do the Luau 0.507 release a bit earlier to end the year sooner. Changes: - Type ascription (::) now permits casts between related types in both directions, allowing to refine or loosen the type (RFC luau-lang#56) - Fix type definition for tonumber to return number? since the input string isn't guaranteed to contain a valid number - Fix type refinements for field access via [] - Many stability fixes for type checker - Provide extra information in error messages for type mismatches in more cases - Improve performance of type checking for large unions when union members are string literals - Add coverage reporting support to Repl (--coverage command line argument) and lua_getcoverage C API - Work around code signing issues during Makefile builds on macOS - Improve performance of truthiness checks in some cases, particularly on Apple M1, resulting in 10-25% perf gains on qsort benchmark depending on the CPU/compiler - Fix support for little-endian systems; IBM s390x here we go!
Sync to upstream/release/506 (luau-lang#270) - Fix some cases where type checking would overflow the native stack - Improve autocomplete behavior when assigning a partially written function call (not currently exposed through command line tools) - Improve autocomplete type inference feedback for some expressions where previously the type would not be known - Improve quantification performance during type checking for large types - Improve type checking for table literals when the expected type of the table is known because of a type annotation - Fix type checking errors in cases where required module has errors in the resulting type - Fix debug line information for multi-line chained call sequences (Add function name information for "attempt to call a nil value" luau-lang#255) - lua_newuserdata now takes 2 arguments to match Lua/LuaJIT APIs better; lua_newuserdatatagged should be used if the third argument was non-0. - lua_ref can no longer be used with LUA_REGISTRYINDEX to prevent mistakes when migrating Lua FFI (Inconsistency with lua_ref luau-lang#247) - Fix assertions and possible crashes when executing script code indirectly via metatable dispatch from lua_equal/lua_lessthan/lua_getfield/etc. (Hitting a crash in an assert after lua_equal is called. luau-lang#259) - Fix flamegraph scripts to run under Python 2
Sync to upstream/release/505 (luau-lang#216) - Improve error recovery during type checking - Initial (not fully complete) implementation for singleton types (RFC RFC: Singleton types luau-lang#37) - Implement a C-friendly interface for compiler (luacode.h) - Remove C++ features from lua.h (removed default arguments from luau_load and lua_pushcfunction) - Fix lua_breakpoint behavior when enabled=false - Implement coroutine.close (RFC RFC: coroutine.close luau-lang#88) Note, this introduces small breaking changes in lua.h: - luau_load env argument is now required, pass an extra 0 - lua_pushcfunction now must be called with 3 arguments; if you were calling it with 2 arguments, pass an extra NULL; if you were calling it with 4, use lua_pushcclosure. These changes are necessary to make sure lua.h can be used from pure C - the future release will make it possible by adding an option to luaconf.h to change function name mangling to be C-compatible. We don't anticipate breaking the FFI interface in the future, but this change was necessary to restore C compatibility. Closes luau-lang#121 Fixes luau-lang#213

Sync to upstream/release/503 (luau-lang#135) - A series of major optimizations to type checking performance on complex programs/types (up to two orders of magnitude speedup for programs involving huge tagged unions) - Fix a few issues encountered by UBSAN (and maybe fix s390x builds) - Fix gcc-11 test builds - Fix a rare corner case where luau_load wouldn't wake inactive threads which could result in a use-after-free due to GC - Fix CLI crash when error object that's not a string escapes to top level - Fix Makefile suffixes on macOS Co-authored-by: Rodactor <[email protected]>
