From 25f91aa8b82fa3a9e415afbb83574c56b43cad80 Mon Sep 17 00:00:00 2001 From: Vighnesh-V Date: Fri, 16 Aug 2024 11:29:33 -0700 Subject: [PATCH 1/3] Sync to upstream/release/639 (#1368) # What's Changed? - Variety of bugfixes in the new solver ## New Solver - Fix an issue where we would hit a recursion limit when applying long chains of type refinements. - Weaken the types of `table.freeze` and `table.clone` in the new solver so we can accept common code patterns like `local a = table.freeze({x=5, x=0})` at the expense of accepting code like `table.freeze(true)`. - Don't warn when the # operator is used on a value of type never ## VM - Fix a bug in lua_resume where too many values might be removed from stack when resume throws an error --- Co-authored-by: Aaron Weiss Co-authored-by: Andy Friesen Co-authored-by: Vighnesh Vijay Co-authored-by: Vyacheslav Egorov --------- Co-authored-by: Aaron Weiss Co-authored-by: Alexander McCord Co-authored-by: Andy Friesen Co-authored-by: Aviral Goel Co-authored-by: David Cope Co-authored-by: Lily Brown Co-authored-by: Vyacheslav Egorov Co-authored-by: Junseo Yoo --- Analysis/src/AstJsonEncoder.cpp | 33 +- Analysis/src/BuiltinDefinitions.cpp | 22 +- Analysis/src/ConstraintGenerator.cpp | 145 +++---- Analysis/src/ConstraintSolver.cpp | 15 +- Analysis/src/Frontend.cpp | 12 +- Analysis/src/Instantiation.cpp | 30 +- Analysis/src/OverloadResolution.cpp | 9 +- Analysis/src/Substitution.cpp | 28 +- Analysis/src/Subtyping.cpp | 5 + Analysis/src/TableLiteralInference.cpp | 4 + Analysis/src/TypeChecker2.cpp | 68 ++-- Analysis/src/TypeFunction.cpp | 167 ++++---- Analysis/src/TypeInfer.cpp | 80 +--- Ast/src/Parser.cpp | 127 ++----- VM/src/ldo.cpp | 18 +- tests/AstJsonEncoder.test.cpp | 8 - tests/AstQuery.test.cpp | 2 + tests/Linter.test.cpp | 4 + tests/Normalize.test.cpp | 8 +- tests/Parser.test.cpp | 5 - tests/TypeInfer.aliases.test.cpp | 62 ++- tests/TypeInfer.builtins.test.cpp | 72 +++- tests/TypeInfer.classes.test.cpp | 96 ++++- tests/TypeInfer.definitions.test.cpp | 4 - tests/TypeInfer.functions.test.cpp | 421 +++++++++++++++------ tests/TypeInfer.intersectionTypes.test.cpp | 116 +++++- tests/TypeInfer.loops.test.cpp | 118 +++++- tests/TypeInfer.modules.test.cpp | 22 +- tests/TypeInfer.oop.test.cpp | 15 +- tests/TypeInfer.operators.test.cpp | 179 ++++++--- tests/TypeInfer.primitives.test.cpp | 25 +- tests/TypeInfer.refinements.test.cpp | 63 +++ tests/TypeInfer.singletons.test.cpp | 54 ++- tests/TypeInfer.test.cpp | 55 ++- tests/TypeInfer.tryUnify.test.cpp | 8 + tests/TypeInfer.typePacks.test.cpp | 85 +++-- tests/TypeInfer.unknownnever.test.cpp | 24 +- tools/faillist.txt | 175 --------- 38 files changed, 1474 insertions(+), 910 deletions(-) diff --git a/Analysis/src/AstJsonEncoder.cpp b/Analysis/src/AstJsonEncoder.cpp index ceeee73c..fd90a6ee 100644 --- a/Analysis/src/AstJsonEncoder.cpp +++ b/Analysis/src/AstJsonEncoder.cpp @@ -8,8 +8,6 @@ #include -LUAU_FASTFLAG(LuauDeclarationExtraPropData) - namespace Luau { @@ -898,19 +896,11 @@ struct AstJsonEncoder : public AstVisitor { // TODO: attributes PROP(name); - - if (FFlag::LuauDeclarationExtraPropData) - PROP(nameLocation); - + PROP(nameLocation); PROP(params); - - if (FFlag::LuauDeclarationExtraPropData) - { - PROP(paramNames); - PROP(vararg); - PROP(varargLocation); - } - + PROP(paramNames); + PROP(vararg); + PROP(varargLocation); PROP(retTypes); PROP(generics); PROP(genericPacks); @@ -926,10 +916,7 @@ struct AstJsonEncoder : public AstVisitor [&]() { PROP(name); - - if (FFlag::LuauDeclarationExtraPropData) - PROP(nameLocation); - + PROP(nameLocation); PROP(type); } ); @@ -940,16 +927,10 @@ struct AstJsonEncoder : public AstVisitor writeRaw("{"); bool c = pushComma(); write("name", prop.name); - - if (FFlag::LuauDeclarationExtraPropData) - write("nameLocation", prop.nameLocation); - + write("nameLocation", prop.nameLocation); writeType("AstDeclaredClassProp"); write("luauType", prop.ty); - - if (FFlag::LuauDeclarationExtraPropData) - write("location", prop.location); - + write("location", prop.location); popComma(c); writeRaw("}"); } diff --git a/Analysis/src/BuiltinDefinitions.cpp b/Analysis/src/BuiltinDefinitions.cpp index 082d79e8..e565f6bf 100644 --- a/Analysis/src/BuiltinDefinitions.cpp +++ b/Analysis/src/BuiltinDefinitions.cpp @@ -374,9 +374,25 @@ void registerBuiltinGlobals(Frontend& frontend, GlobalTypes& globals, bool typeC if (TableType* ttv = getMutable(getGlobalBinding(globals, "table"))) { - // tabTy is a generic table type which we can't express via declaration syntax yet - ttv->props["freeze"] = makeProperty(makeFunction(arena, std::nullopt, {tabTy}, {tabTy}), "@luau/global/table.freeze"); - ttv->props["clone"] = makeProperty(makeFunction(arena, std::nullopt, {tabTy}, {tabTy}), "@luau/global/table.clone"); + if (FFlag::DebugLuauDeferredConstraintResolution) + { + // CLI-114044 - The new solver does not yet support generic tables, + // which act, in an odd way, like generics that are constrained to + // the top table type.

3.1.4

This is the Jinja 3.1.4 security release, which fixes security issues and bugs but does not otherwise change behavior and should not result in breaking changes.

PyPI: https://pypi.org/project/Jinja2/3.1.4/ Changes: https://jinja.palletsprojects.com/en/3.1.x/changes/#version-3-1-4

  • The xmlattr filter does not allow keys with / solidus, > greater-than sign, or = equals sign, in addition to disallowing spaces. Regardless of any validation done by Jinja, user input should never be used as keys to this filter, or must be separately validated first. GHSA-h75v-3vvj-5mfj
