From 44e827bcc9b3116d8c3f5d998ae0937073a4b511 Mon Sep 17 00:00:00 2001 From: Anders Hejlsberg Date: Tue, 15 Feb 2022 19:30:29 +0100 Subject: [PATCH] Eliminate redundant or meaningless elaborations in type relations (#47738) * Eliminate redundant or meaningless elaborations in type relations * Accept new baselines * Add resetErrorInfo (though, oddly, shouldn't be necessary) * Less aggressive reduction in second pass union/intersection checks * Accept new baselines * Restructure and back off a little bit more * Only cache union/intersection relations once * Accept new baselines * Properly cache identity relations, clean up error reporting * Move more logic to cached side of relation checks * Optimize and remove more redundant elaborations * Accept new baselines * Remove unnecessary error state capture * More optimizing * Cache isWeakType computation * Revert "Cache isWeakType computation" This reverts commit 25a71c4de61f6366ffac080d19685dcb200f42b9. * Address CR feedback * Accept new baselines --- src/compiler/checker.ts | 585 +++++++++--------- src/compiler/diagnosticMessages.json | 8 + src/compiler/types.ts | 2 + .../reference/bigintWithLib.errors.txt | 2 - ...ckJsdocTypeTagOnObjectProperty2.errors.txt | 4 +- .../checkJsxChildrenProperty4.errors.txt | 4 - ...nalNoInfiniteInstantiationDepth.errors.txt | 152 ++--- .../reference/conditionalTypes2.errors.txt | 6 - .../reference/constructBigint.errors.txt | 2 - .../decoratorOnClassMethod8.errors.txt | 6 +- ...ectBindingPatternAndAssignment3.errors.txt | 2 - .../divergentAccessorsTypes2.errors.txt | 4 +- .../reference/inferTypes1.errors.txt | 2 - ...ExtendsObjectIntersectionErrors.errors.txt | 4 +- .../intersectionAndUnionTypes.errors.txt | 6 - .../intersectionPropertyCheck.errors.txt | 8 +- ...intersectionWithUnionConstraint.errors.txt | 10 - ...insicElementsTypeArgumentErrors.errors.txt | 4 - .../reference/mappedTypeErrors.errors.txt | 26 +- .../reference/mappedTypeErrors2.errors.txt | 2 - .../mappedTypeRelationships.errors.txt | 12 - .../nonPrimitiveAndTypeVariables.errors.txt | 4 - .../reference/objectCreate-errors.errors.txt | 24 +- .../objectLiteralNormalization.errors.txt | 4 +- .../potentiallyUncalledDecorators.errors.txt | 88 +-- ...ferredInferenceAllowsAssignment.errors.txt | 152 ++--- .../tsxLibraryManagedAttributes.errors.txt | 12 +- .../typeFromJSInitializer.errors.txt | 4 +- .../typeParameterDiamond3.errors.txt | 4 - .../types.asyncGenerators.es2018.2.errors.txt | 2 - .../unionTypesAssignability.errors.txt | 2 - .../reference/unknownType1.errors.txt | 2 - .../reference/variadicTuples1.errors.txt | 4 +- 33 files changed, 442 insertions(+), 711 deletions(-) diff --git a/src/compiler/checker.ts b/src/compiler/checker.ts index c38d9c2a0416a..afe904e93040e 100644 --- a/src/compiler/checker.ts +++ b/src/compiler/checker.ts @@ -199,8 +199,7 @@ namespace ts { Source = 1 << 0, Target = 1 << 1, PropertyCheck = 1 << 2, - UnionIntersectionCheck = 1 << 3, - InPropertyCheck = 1 << 4, + InPropertyCheck = 1 << 3, } const enum RecursionFlags { @@ -18006,13 +18005,13 @@ namespace ts { let overflow = false; let overrideNextErrorInfo = 0; // How many `reportRelationError` calls should be skipped in the elaboration pyramid let lastSkippedInfo: [Type, Type] | undefined; - let incompatibleStack: [DiagnosticMessage, (string | number)?, (string | number)?, (string | number)?, (string | number)?][] = []; + let incompatibleStack: [DiagnosticMessage, (string | number)?, (string | number)?, (string | number)?, (string | number)?][] | undefined; let inPropertyCheck = false; Debug.assert(relation !== identityRelation || !errorNode, "no error reporting in identity checking"); const result = isRelatedTo(source, target, RecursionFlags.Both, /*reportErrors*/ !!errorNode, headMessage); - if (incompatibleStack.length) { + if (incompatibleStack) { reportIncompatibleStack(); } if (overflow) { @@ -18074,21 +18073,21 @@ namespace ts { return { errorInfo, lastSkippedInfo, - incompatibleStack: incompatibleStack.slice(), + incompatibleStack: incompatibleStack?.slice(), overrideNextErrorInfo, - relatedInfo: !relatedInfo ?
