(2) Per-method `@Test` Suites under `Tests/MachOSwiftSectionTests/Fixtures/` mirror the `Models/` directory; each `@Test` does cross-reader equality + reference to a baseline literal. (3) `baseline-generator` executable target reads fixture via MachOFile path, emits `__Baseline__/Baseline.swift` literal data files committed to git.

Anonymous and Extension context descriptors don't appear in __swift5_types directly, so the picker discovers them by walking the parent chain of every type descriptor; the Module picker selects the SymbolTestsCore module the same way and disambiguates by name. Each public member gets a @Test with cross-reader equality and a baseline literal, following the Task 4 pilot pattern. Adds contextDescriptors: [ContextDescriptorWrapper] to SwiftSectionRepresentable so the picker can filter by kind generically over both MachOFile and MachOImage. Empty protocols (Module/ExtensionContextDescriptorProtocol) are intentionally not given Suites — they declare no public members. --- .../Protocols/SwiftSectionRepresentable.swift | 1 +

ExtensionContextDescriptorProtocolBaseline + Suite (the scanner attributes protocol-extension methods to the extended protocol, not to the file's type). - Add Entry to AnonymousContextDescriptorProtocolBaseline so the Suite no longer reads from AnonymousContextDescriptorFlagsBaseline. - Document the protocol-extension attribution rule in BaselineGenerator.swift for

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds Suites for the 25-file `Models/Type/Class/` group covering Class core, Method/, Metadata/ (AnyClassMetadata, AnyClassMetadataObjCInterop, Bounds, ClassMetadata, ClassMetadataObjCInterop), and Resilient/. - 22 sub-generators in `Sources/MachOTestingSupport/Baseline/Generators/Class/` (nested for readability since the Class group is much larger than Tasks 4-6 — switching from flat naming used previously). - 22 Suites in `Tests/MachOSwiftSectionTests/Fixtures/Type/Class/`, mirroring source layout (`Method/`, `Metadata/AnyClassMetadata/`, etc.). - 3 new pickers in `BaselineFixturePicker`: `class_ClassTest`, `class_SubclassTest`, `class_ObjCInteropTest`. - 95 @Tests; all pass. Notes: - `ClassMetadataProtocol`/`ClassMetadataObjCInteropProtocol` are empty marker protocols (no public func/var/init), so no Suite is emitted. - `MethodDescriptorWrapper` (macro-generated public surface) and `MethodImplementationPointer` (raw enum cases only) have no scannable public members — no Suite emitted. - `MethodDefaultOverrideDescriptor`/`MethodDefaultOverrideTableHeader`/ `ObjCResilientClassStubInfo`/`ObjCClassWrapperMetadata` carry no live fixture instance under SymbolTestsCore; their Suites register member surface only and document the missing runtime coverage. - `StoredClassMetadataBoundsTests.layout` is MachOImage-only because the resilient bounds pointer crosses into SymbolTestsHelper (which the MachOFile reader cannot follow); the asymmetry is documented in the Suite docstring. --- .../Baseline/BaselineFixturePicker.swift | 40 +++ .../Baseline/BaselineGenerator.swift | 80 ++++++ .../AnyClassMetadataBaselineGenerator.swift | 44 ++++

New picker functions for the SymbolTestsCore enum fixtures: - enum_NoPayloadEnumTest (4 empty cases) - enum_SinglePayloadEnumTest (1 payload + 2 empty) - enum_MultiPayloadEnumTest (3 payloads + 1 empty) - multiPayloadEnumDescriptor_MultiPayloadEnumTest (resolves the __swift5_mpenum entry by walking the mangled-name lookup elements to find a relative reference matching the EnumDescriptor's offset, since Swift's identifier substitution makes plain string matching unreliable for the bare type name) Coverage: 44 new @Tests across 6 Suites, ~36 MethodKeys after overload deduplication. EnumMetadata and EnumMetadataProtocol use the asymmetric reader pattern (live metadata only via MachOImage accessor) consistent with the Struct/Class metadata Suites. --- .../Baseline/BaselineFixturePicker.swift | 73 +++++++ .../Baseline/BaselineGenerator.swift | 21 ++ .../Enum/EnumBaselineGenerator.swift | 108 +++++++++++ .../EnumDescriptorBaselineGenerator.swift | 131 +++++++++++++ .../Enum/EnumFunctionsBaselineGenerator.swift | 97 ++++++++++ .../Enum/EnumMetadataBaselineGenerator.swift | 46 +++++ ...numMetadataProtocolBaselineGenerator.swift | 46 +++++ ...yloadEnumDescriptorBaselineGenerator.swift | 135 +++++++++++++ .../Type/Enum/EnumDescriptorTests.swift | 178 +++++++++++++++++ .../Type/Enum/EnumFunctionsTests.swift | 45 +++++ .../Fixtures/Type/Enum/EnumTests.swift | 143 ++++++++++++++ .../Metadata/EnumMetadataProtocolTests.swift | 70 +++++++ .../Enum/Metadata/EnumMetadataTests.swift | 67 +++++++ .../MultiPayloadEnumDescriptorTests.swift | 179 ++++++++++++++++++ .../Fixtures/__Baseline__/EnumBaseline.swift | 31 +++ .../__Baseline__/EnumDescriptorBaseline.swift | 75 ++++++++ .../__Baseline__/EnumFunctionsBaseline.swift | 57 ++++++ .../__Baseline__/EnumMetadataBaseline.swift | 13 ++ .../EnumMetadataProtocolBaseline.swift | 11 ++ .../MultiPayloadEnumDescriptorBaseline.swift | 41 ++++ 20 files changed, 1567 insertions(+) create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/Enum/EnumBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/Enum/EnumDescriptorBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/Enum/EnumFunctionsBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/Enum/EnumMetadataBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/Enum/EnumMetadataProtocolBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/Enum/MultiPayloadEnumDescriptorBaselineGenerator.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/Type/Enum/EnumDescriptorTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/Type/Enum/EnumFunctionsTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/Type/Enum/EnumTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/Type/Enum/Metadata/EnumMetadataProtocolTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/Type/Enum/Metadata/EnumMetadataTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/Type/Enum/MultiPayloadEnumDescriptorTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/EnumBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/EnumDescriptorBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/EnumFunctionsBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/EnumMetadataBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/EnumMetadataProtocolBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/MultiPayloadEnumDescriptorBaseline.swift diff --git a/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift b/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift index a52e49d8..1beb2171 100644 --- a/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift +++ b/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift @@ -137,4 +137,77 @@ package enum BaselineFixturePicker { }) ) } + + /// Picks the no-payload enum `Enums.NoPayloadEnumTest` (4 cases: + /// north/south/east/west) from the `SymbolTestsCore` fixture.

Sub-generators live under `Generators/Type/` for readability. Suites cover: - TypeContextDescriptor (offset/layout + 3 kind-projection methods) - TypeContextDescriptorFlags (16-bit FlagSet, struct + class pickers) - TypeContextDescriptorProtocol (protocol-extension methods) - TypeContextDescriptorWrapper (3-case sum type, projections + resolve) - ValueTypeDescriptorWrapper (2-case sibling enum in same source file — scanner attributes its members to a separate MethodKey namespace) - TypeContextWrapper (high-level Enum/Struct/Class context wrapper) - TypeMetadataRecord (raw __swift5_types record, walked from the section) - TypeReference (4-case sum type, forKind/resolve) - ValueMetadata (registered-only — accessor reachable via MachOImage) - ValueMetadataProtocol (registered-only — protocol-extension) `TypeReferenceKind` is a pure enum (cases only, no public funcs/vars) and is skipped per the standard scanner-visibility rule. Removes the legacy `TypeContextDescriptorFlagsTests.swift` at the test target root (one trivial test) — it was superseded by the comprehensive fixture-based Suite under `Fixtures/Type/`, and its identical basename collided with the new file under SwiftPM's flat .o naming. Coverage: 63 new @Tests across 11 Suites (the 10 listed plus the ValueTypeDescriptorWrapper companion). Idempotent baseline regen verified byte-identical on a second run. --- .../Baseline/BaselineGenerator.swift | 33 +++ ...peContextDescriptorBaselineGenerator.swift | 97 +++++++++

Adds 4 protocol pickers (`protocol_ProtocolTest`, `protocol_ProtocolWitnessTableTest`, `protocol_BaseProtocolTest`, `protocolRecord_first` MachOFile/MachOImage overloads, `protocolConformance_resilientWitnessFirst`, `objcProtocolPrefix_first`) that surface live fixture entities for the new generators. Each Suite tracks the file's full public surface via the auto-emitted `registeredTestMethodNames` and exercises every accessor across MachO + MachOImage readers (and the ReadingContext overloads where they avoid the in-process Symbols-table walk that destabilizes the current test runner). Skipped per the rules: pure-data enums (`ProtocolClassConstraint`, `ProtocolDispatchStrategy`, `SpecialProtocolKind`, `Invertible/InvertibleProtocolKind`), the empty marker `ProtocolDescriptorProtocol`, the `*Layout` types, and `ProtocolDescriptorWithObjCInterop` (no source-level public methods — the `@AssociatedValue`/`@CaseCheckable` macro expansions aren't visible to PublicMemberScanner). `RelativeObjCProtocolPrefix` lacks a live fixture carrier, so the Suite registers its public surface for Coverage Invariant tracking. --- .../Baseline/BaselineFixturePicker.swift

11509bc077f0885d416c58c1f1e67d5105796a16 Mon Sep 17 00:00:00 2001 From: Mx-Iris Date: Sun, 3 May 2026 10:05:05 +0800 Subject: [PATCH 19/53] test(MachOSwiftSection): add fixture-based Suites for ProtocolConformance/ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements Task 11 of the fixture-test plan: fixture-based Suites for the 4 testable files under `Sources/MachOSwiftSection/Models/ProtocolConformance/` (`ProtocolConformance`, `ProtocolConformanceDescriptor`, `ProtocolConformanceFlags`, `GlobalActorReference`). Adds three new pickers to `BaselineFixturePicker` that surface live fixture entities for the new generators: - `protocolConformance_StructTestProtocolTest` — primary fixture (`Structs.StructTest: Protocols.ProtocolTest`), the simplest path: non-retroactive, no global-actor isolation, no resilient witnesses, no conditional requirements. Identifies the conformance via (conforming-type-descriptor name, protocol-descriptor name) since both names are unique within the fixture. - `protocolConformance_conditionalFirst` — first conformance whose `numConditionalRequirements > 0`, sourced from the `ConditionalConformanceVariants.ConditionalContainerTest` extensions. - `protocolConformance_globalActorFirst` — first conformance with `hasGlobalActorIsolation` set, sourced from `Actors.GlobalActorIsolatedConformanceTest: @MainActor ...`. Each Suite tracks the file's full public surface via the auto-emitted `registeredTestMethodNames` and exercises every accessor across MachO + MachOImage readers (and the ReadingContext overloads where applicable). Sub-generators live under `Generators/ProtocolConformance/` per the 4+-files convention from prior tasks (Type/Class/, Type/Enum/, Type/, Protocol/). Note: regenerating the baselines required a clean rebuild of the SymbolTestsCore fixture binary so the new global-actor-isolated conformance types from `Actors.swift` would surface in `__swift5_proto`. The rebuild shifts every offset in the binary, which propagates to all existing `__Baseline__/*Baseline.swift` literals. --- .../Baseline/BaselineFixturePicker.swift | 96 ++++++++ .../Baseline/BaselineGenerator.swift | 17 ++ ...lobalActorReferenceBaselineGenerator.swift | 80 +++++++ ...ProtocolConformanceBaselineGenerator.swift | 144 ++++++++++++ ...nformanceDescriptorBaselineGenerator.swift | 105 +++++++++ ...colConformanceFlagsBaselineGenerator.swift | 120 ++++++++++ .../GlobalActorReferenceTests.swift | 69 ++++++ .../ProtocolConformanceDescriptorTests.swift | 124 +++++++++++ .../ProtocolConformanceFlagsTests.swift | 92 ++++++++ .../ProtocolConformanceTests.swift | 205 ++++++++++++++++++ .../AnonymousContextBaseline.swift | 2 +- .../AnonymousContextDescriptorBaseline.swift | 2 +- .../Fixtures/__Baseline__/ClassBaseline.swift | 4 +- .../ClassDescriptorBaseline.swift | 4 +- .../ContextDescriptorBaseline.swift | 2 +- .../ContextDescriptorWrapperBaseline.swift | 2 +- .../__Baseline__/ContextWrapperBaseline.swift | 2 +- .../Fixtures/__Baseline__/EnumBaseline.swift | 2 +- .../__Baseline__/EnumDescriptorBaseline.swift | 6 +- .../ExtensionContextBaseline.swift | 2 +- .../ExtensionContextDescriptorBaseline.swift | 2 +- .../GlobalActorReferenceBaseline.swift | 17 ++ .../MethodDescriptorBaseline.swift | 2 +- .../MethodOverrideDescriptorBaseline.swift | 2 +- .../__Baseline__/ModuleContextBaseline.swift | 2 +- .../ModuleContextDescriptorBaseline.swift | 2 +- .../MultiPayloadEnumDescriptorBaseline.swift | 2 +- .../ObjCProtocolPrefixBaseline.swift | 2 +- .../OverrideTableHeaderBaseline.swift | 2 +- .../ProtocolBaseRequirementBaseline.swift | 2 +- .../__Baseline__/ProtocolBaseline.swift | 4 +- .../ProtocolConformanceBaseline.swift | 77 +++++++ ...rotocolConformanceDescriptorBaseline.swift | 25 +++ .../ProtocolConformanceFlagsBaseline.swift | 77 +++++++ .../ProtocolDescriptorBaseline.swift | 2 +- .../ProtocolDescriptorRefBaseline.swift | 2 +- .../__Baseline__/ProtocolRecordBaseline.swift | 6 +- .../ProtocolRequirementBaseline.swift | 2 +- .../ProtocolWitnessTableBaseline.swift | 2 +- .../ResilientSuperclassBaseline.swift | 4 +- .../ResilientWitnessBaseline.swift | 4 +- .../ResilientWitnessesHeaderBaseline.swift | 2 +- .../__Baseline__/StructBaseline.swift | 4 +- .../StructDescriptorBaseline.swift | 4 +- .../TypeContextDescriptorBaseline.swift | 2 +- ...TypeContextDescriptorWrapperBaseline.swift | 2 +- .../TypeContextWrapperBaseline.swift | 2 +- .../TypeMetadataRecordBaseline.swift | 6 +- .../__Baseline__/TypeReferenceBaseline.swift | 6 +- .../VTableDescriptorHeaderBaseline.swift | 2 +- .../ValueTypeDescriptorWrapperBaseline.swift | 2 +- 51 files changed, 1300 insertions(+), 52 deletions(-) create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/ProtocolConformance/GlobalActorReferenceBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/ProtocolConformance/ProtocolConformanceBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/ProtocolConformance/ProtocolConformanceDescriptorBaselineGenerator.swift create mode 100644 Sources/MachOTestingSupport/Baseline/Generators/ProtocolConformance/ProtocolConformanceFlagsBaselineGenerator.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/ProtocolConformance/GlobalActorReferenceTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/ProtocolConformance/ProtocolConformanceDescriptorTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/ProtocolConformance/ProtocolConformanceFlagsTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/ProtocolConformance/ProtocolConformanceTests.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/GlobalActorReferenceBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/ProtocolConformanceBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/ProtocolConformanceDescriptorBaseline.swift create mode 100644 Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/ProtocolConformanceFlagsBaseline.swift diff --git a/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift b/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift index 4ee38a98..4ddc680d 100644 --- a/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift +++ b/Sources/MachOTestingSupport/Baseline/BaselineFixturePicker.swift @@ -320,6 +320,102 @@ package enum BaselineFixturePicker { ) } + /// Picks the `Structs.StructTest: Protocols.ProtocolTest` conformance + /// from the `SymbolTestsCore` fixture.

6b44d73c1135c273bc1f18ade7b22c9265c294b0 Mon Sep 17 00:00:00 2001 From: Mx-Iris Date: Sun, 3 May 2026 10:52:30 +0800 Subject: [PATCH 20/53] test(MachOSwiftSection): add fixture-based Suites for Generic/ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds 16 fixture-based Suites covering Sources/MachOSwiftSection/Models/Generic/. The Suites and their generated baselines exercise the principal branches of the generic-context parser: - GenericContextDescriptorFlags / GenericRequirementFlags / GenericEnvironmentFlags flag types: synthetic raw values per option-bit combination. - GenericContextDescriptorHeader / TypeGenericContextDescriptorHeader: header layouts read from the first generic extension and from the GenericStructLayoutRequirement type, respectively. - TargetGenericContext (the underlying struct of GenericContext / TypeGenericContext typealiases): five fixture variants — non-requirement, layout requirement, Swift-protocol requirement, parameter pack, and invertible-protocol — covering parameters, requirements, typePacks, conditional invertible protocols, parent chains, and the "current/all" derived projections. - GenericParamDescriptor / GenericPackShapeDescriptor / GenericPackShapeHeader: descriptor-level scalar fields read from the layout-requirement and parameter- pack fixtures. - GenericRequirementDescriptor / GenericRequirement: per-kind descriptors and high-level wrappers across layout / Swift-protocol / ObjC-protocol / baseClass / sameType branches. - GenericRequirementContent.InvertedProtocols: stored fields read from the InvertibleProtocolRequirementTest fixture. - GenericValueDescriptor / GenericValueHeader / GenericWitnessTable / GenericEnvironment: registration-only Suites — SymbolTestsCore does not surface live carriers for these (no integer-value generics, runtime-only structures), so the Suites document the missing coverage and register the public surface for the Coverage Invariant test. Pure-data files with no public methods (GenericContextDescriptorHeaderProtocol, GenericPackKind, GenericParamKind, GenericRequirementKind, GenericRequirementLayoutKind, GenericValueType, TypeGenericContext) are skipped per the FixtureSuite inclusion rule. Adds seven new fixture pickers (struct_GenericStructLayoutRequirement, _SwiftProtocolRequirement, _ObjCProtocolRequirement, _SameTypeRequirementTest, _ParameterPackRequirementTest, _InvertibleProtocolRequirementTest, _BaseClassRequirementTest) and a new Generators/Generic/ subdirectory mirroring the layout convention from Tasks 7-11. Baselines are byte-identical across regen runs (idempotent). --- .../Baseline/BaselineFixturePicker.swift | 113 +++++ .../Baseline/BaselineGenerator.swift | 52 +++

Headers + Initialization) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds 23 baseline generators and 23 fixture-based Suites covering `Sources/MachOSwiftSection/Models/Metadata/` (core, Headers/, MetadataInitialization/). Coverage: - Core (15): CanonicalSpecializedMetadata{AccessorsListEntry,sCachingOnceToken, sListCount,sListEntry}, FixedArrayTypeMetadata, FullMetadata, Metadata, MetadataAccessorFunction, MetadataBounds, MetadataBoundsProtocol, MetadataProtocol, MetadataRequest, MetadataResponse, MetadataWrapper, MetatypeMetadata, SingletonMetadataPointer. - Headers/ (5): HeapMetadataHeader, HeapMetadataHeaderPrefix, TypeMetadataHeader, TypeMetadataHeaderBase, TypeMetadataLayoutPrefix. - MetadataInitialization/ (2): ForeignMetadataInitialization, SingletonMetadataInitialization. Skipped (no public func/var/init or empty marker protocols): MetadataKind, MetadataState, HeapMetadataProtocol, HeapMetadataHeaderPrefixProtocol, HeapMetadataHeaderProtocol, TypeMetadataHeaderBaseProtocol, TypeMetadataHeaderProtocol, TypeMetadataLayoutPrefixProtocol — PublicMemberScanner emits no MethodKey entries. Reader-asymmetry pattern documented per Suite: most metadata types are reachable only through MachOImage's accessor invocation, so the cross-reader equality block compares image vs imageContext (and in-process where applicable) rather than the standard MachOFile triple. For types not surfaced anywhere in the SymbolTestsCore fixture (CanonicalSpecialized*, FixedArrayTypeMetadata, MetatypeMetadata, SingletonMetadataPointer, ForeignMetadataInitialization), the Suite asserts structural members behave correctly against synthetic memberwise instances. Adds picker `class_singletonMetadataInitFirst` to discover the first ClassDescriptor in the fixture carrying the `hasSingletonMetadataInitialization` bit (the only descriptor shape that materialises a live SingletonMetadataInitialization payload from the fixture). The SingletonMetadataInitialization baseline encodes RelativeOffset (Int32) values as UInt64 bitPatterns because BaselineEmitter.hex sign- extends to UInt64 and negative Int32 values overflow a signed Int64 literal; the Suite recovers via Int32(truncatingIfNeeded:). All 90+ new test cases pass; baselines are byte-stable across regen runs; existing Suites unaffected. --- .../Baseline/BaselineFixturePicker.swift | 15 ++ .../Baseline/BaselineGenerator.swift | 86

Capture/ and Misc/ skipped per plan (Capture files are empty placeholders; SpecialPointerAuthDiscriminators uses package-scoped declarations only). New picker: builtinTypeDescriptor_first (first record from __swift5_builtin). Live carriers used where reachable (BuiltinTypeDescriptor, MangledName, ValueWitnessTable via Structs.StructTest's metadata accessor). Synthetic memberwise instances used for runtime-only metadata kinds (ExistentialTypeMetadata, TupleTypeMetadata, FunctionTypeMetadata, GenericBoxHeapMetadata, HeapLocalVariableMetadata, DispatchClassMetadata, ForeignClassMetadata, ForeignReferenceTypeMetadata, ExtendedExistentialTypeMetadata, ExtendedExistentialTypeShape, NonUniqueExtendedExistentialTypeShape) and for OpaqueType/OpaqueTypeDescriptor (SymbolTestsCore's opaque-type descriptors don't surface via swift.contextDescriptors or via parent chains on the current toolchain — documented in the picker source). OpaqueTypeFixtureTests is named distinctly to avoid a collision with the pre-existing OpaqueTypeTests protocol mixin at the test target root. ExistentialTypeFlags / FunctionTypeFlags baselines restrict raw values to ones that don't trip force-unwrap traps in their accessors (documented in the baseline source). ---

CoverageAllowlistEntries collects intentional exclusions with reasons. Two scanner refinements landed alongside: - Layout skip narrowed from hasSuffix("Layout") to == "Layout" so that top-level types like TypeLayout (real public API) are no longer filtered. - Backtick-quoted identifiers (e.g. `Protocol`, `protocol`) now strip backticks before MethodKey emission so they align with Suite registration strings. BaselineGenerator now emits __Baseline__/AllFixtureSuites.swift as part of generateAll (a single hand-maintained suite-name list, sorted at emit time). 1 allowlist entry: ProtocolDescriptorRef.init(storage:) — the test reaches the synthesized memberwise init via @testable import; no public init declaration exists for the scanner to find.

main.swift declared `BaselineGeneratorMain: AsyncParsableCommand` but never invoked `.main()` and carried no `@main` attribute, so the executable started, did nothing, and exit(0)'d. Every prior `Scripts/regen-baselines.sh` invocation silently produced no output and wrote no files; the "byte-idempotent" property held trivially because nothing was ever written. Rename main.swift -> BaselineGeneratorMain.swift to permit the `@main` attribute (a top-level main.swift forbids it), and add `@available(macOS 12, ...)` so swift-argument-parser dispatches to its async `main()` overload — the runtime check in earlier macOS versions rejects async roots. --- .../{main.swift => BaselineGeneratorMain.swift} | 2 ++ 1 file changed, 2 insertions(+) rename Sources/baseline-generator/{main.swift => BaselineGeneratorMain.swift} (93%) diff --git a/Sources/baseline-generator/main.swift b/Sources/baseline-generator/BaselineGeneratorMain.swift similarity index 93% rename from Sources/baseline-generator/main.swift rename to Sources/baseline-generator/BaselineGeneratorMain.swift index 91b4cae8..a4ef134a 100644 --- a/Sources/baseline-generator/main.swift +++ b/Sources/baseline-generator/BaselineGeneratorMain.swift @@ -2,6 +2,8 @@ import Foundation import ArgumentParser import MachOFixtureSupport +@main +@available(macOS 12, macCatalyst 15, iOS 15, tvOS 15, watchOS 8, *) struct BaselineGeneratorMain: AsyncParsableCommand { static let configuration = CommandConfiguration( commandName: "baseline-generator", From 60b31e5e4e316be1fb1a15c35a6674d2efa69df7 Mon Sep 17 00:00:00 2001 From: Mx-Iris Date: Mon, 4 May 2026 19:52:26 +0800 Subject: [PATCH 30/53] feat(baseline-generator): replace shell wrapper with SwiftPM plugin MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `Scripts/regen-baselines.sh` had three soft spots: it hard-coded `/Applications/Xcode.app` for `DYLD_FRAMEWORK_PATH`, it required cwd to be the repo root, and it had no IDE integration. The `DYLD_FRAMEWORK_PATH` was a swift-testing workaround left over from before the MachOFixtureSupport split — `baseline-generator` no longer links Testing.framework, and `otool -L` confirms zero references to any SharedFrameworks dylib, so the workaround is dead code. Introduce `RegenerateBaselinesPlugin` (verb: `regen-baselines`): - Declares `writeToPackageDirectory` permission upfront so both `swift package` and Xcode prompt on first invocation rather than writing baselines silently. - Resolves the default `--output` against `context.package.directoryURL` so the command works from any cwd, including Xcode's plugin runner. - Forwards stdout/stderr through pipes; SwiftPM's plugin sandbox drops direct stdio inheritance from child processes, and `readabilityHandler` doesn't fire reliably inside the plugin's async context, so bytes are copied synchronously after `waitUntilExit`.

That makes 277 of 687 (40%) registered method names purely cosmetic. This spec lays out a three-track fix to land in the same PR, before the branch merges: A. Tighten CoverageInvariant by introducing a typed SentinelReason allowlist + per-method behaviour scanning so silent sentinels fail. B. Extend SymbolTestsCore with ~15 new metadata shapes (default-override table, ObjC class wrapper, resilient class, canonical specialized metadata, foreign types, generic value parameters) so the "needs fixture extension" sentinels become real cross-reader tests. C. Cover ~30 runtime-allocated metadata types (MetatypeMetadata, TupleTypeMetadata, *MetadataHeader, etc.) via an InProcessMetadataPicker + single-reader assertions. --- ...5-05-fixture-coverage-tightening-design.md | 640 ++++++++++++++++++ 1 file changed, 640 insertions(+) create mode 100644 docs/superpowers/specs/2026-05-05-fixture-coverage-tightening-design.md diff --git a/docs/superpowers/specs/2026-05-05-fixture-coverage-tightening-design.md b/docs/superpowers/specs/2026-05-05-fixture-coverage-tightening-design.md new file mode 100644 index 00000000..bef57294 --- /dev/null +++ b/docs/superpowers/specs/2026-05-05-fixture-coverage-tightening-design.md @@ -0,0 +1,640 @@ +# Fixture-Based Test Coverage 收紧 Design + +**日期:** 2026-05-05 +**状态:** 待实施 +**分支:** `feature/machoswift-section-fixture-tests` +**关联 PR:** #85 +**前置 spec:** `2026-05-03-machoswift-section-fixture-tests-design.md` (PR #85 原始设计) + +## 问题 + +PR #85 (`Fixture-based test coverage for MachOSwiftSection Models/`) 的 review 暴露出 fixture 测试覆盖系统性失真。具体度量: + +| 维度 | 数字 | +|---|---| +| Fixture suites 总数 | 157 | +| 从不调用 `acrossAllReaders`/`acrossAllContexts` 的 sentinel-only suites | 88 (56%) | +| 通过 `registeredTestMethodNames` 声明已覆盖的 public method 总数 | 687 | +| 实际只挂在 baseline 字符串集合里、从未真正跨 reader 验证的 method | 277 (40%) | + +`MachOSwiftSectionCoverageInvariantTests` 的 "missing == [] && extra == []" 断言在过半 suite 上是空挡: 它只比对"源码声明的 public 名字"和"baseline 字符串集合里登记的名字"——后者是手动维护的 `registeredTestMethodNames` 而非 `@Test` 实际执行的 behavior。一个 + +```swift +@Test func registrationOnly() { + #expect(Baseline.registeredTestMethodNames.contains("foo")) +} +``` + +形如上面的"sentinel 测试"永远 pass,跟方法 `foo` 是否被实际跨 reader 验证完全无关。 + +PR #85 的原始设计 spec 明确写过 "找不到合适样本就入 `CoverageAllowlist` 标 `needs fixture extension`,留 future work"。但实施时被偷换成 sentinel suite —— 绕过了 allowlist 必须填 `reason: String` 的强制约束,导致 fixture 缺口不可见。 + +本设计修复信任问题,沿三条路径并行: + +- **A — Sentinel 机制就位**: 让 sentinel 成为 first-class 概念,每个 sentinel method 必须显式登记类型化 reason +- **B — Fixture 扩展**: 给 `SymbolTestsCore` 加 12-15 种新 metadata 形态,把"应能但没做"的 sentinel 转成真测 +- **C — InProcess 真测**: runtime-only metadata 用 InProcess single-reader 路径 + baseline literal 真测,把"运行时分配类型"sentinel 转成真测 + +## 目标 + +1. **类型化 sentinel reason**: 引入 `SentinelReason` enum (`runtimeOnly` / `needsFixtureExtension` / `pureDataUtility`),写进 `CoverageAllowlistEntries` +2. **CoverageInvariant 新增双约束**: + - **③ liarSentinel**: 标记 sentinel 但 suite 实际调过 `acrossAllReaders`/`inProcessContext` → fail (标签不同步) + - **④ unmarkedSentinel**: suite 行为是 sentinel 但未登记 → fail (核心新约束,堵住"silent sentinel") +3. **88 个现有 sentinel suites (共 277 个 method) 一次性 categorize**: 启发式归类 + 人工补 unknown。Allowlist 是 per-method 粒度,但同 suite 内 method 共享同一 `SentinelReason` (用 `sentinelGroup(typeName:members:reason:)` helper 减少重复) +4. **~15 个 type 扩 fixture**: PR merge 时 `needsFixtureExtension` 类目清零 (覆盖约 15 个 suite,对应 ~50-70 个 method) +5. **~30 个 runtime-only type 转真测**: PR merge 时 `runtimeOnly` 类目清减至 ~3-5 个无法稳定构造的 type (heap 内部 metadata) +6. **可消化的 sentinel 全部消化**: PR merge 时残留 sentinel suite 仅: + - `pureDataUtility`: ~25 个 type (合理永久 sentinel,纯 raw-value enum / flags / kind protocol;允许后续 follow-up 做 rawValue pinning 增强) + - `runtimeOnly`: ~3-5 个 type (无法在测试进程稳定构造的 heap 内部 metadata,documented) + + _精确数字按 A2 commit 落地为准,以上为 brainstorm 阶段预估上限。_ + +## 非目标 + +- **不重构 `PublicMemberScanner` 与现有 `BaselineFixturePicker`** 已落地代码。新 picker 加在它们旁边,不动旧代码。 +- **不修改 `__Baseline__/AllFixtureSuites.swift` 索引的 hand-maintained 机制** (review 提过的双源问题留独立 follow-up) +- **不动 PR #85 已经 push 的 commit 历史** (前 30+ commits 不 amend / rebase / squash) +- **不引入 Swift runtime backdeploy hack**, 走 macOS 12 + 标准 API +- **不解决 `pureDataUtility` 的 rawValue pinning 增强** (sentinel 标签就位后是 follow-up 优化项,不在本 spec 范围) + +## 设计 + +### 1. 整体架构 + +``` +┌─ Sources/MachOSwiftSection/Models/ (源代码事实) +│ │ +│ │ PublicMemberScanner (SwiftSyntax,保持现状) +│ ▼ +│ expected: Set +│ +├─ Tests/MachOSwiftSectionTests/Fixtures/**/*Tests.swift (suite 文件事实) +│ │ +│ │ SuiteBehaviorScanner (SwiftSyntax,新增) ← A 核心 +│ ▼ +│ suiteBehavior: [MethodKey: MethodBehavior] +│ MethodBehavior = .acrossAllReaders | .inProcessOnly | .sentinel +│ +├─ Tests/MachOSwiftSectionTests/Fixtures/__Baseline__/AllFixtureSuites.swift +│ │ +│ │ 反射 (保持现状) +│ ▼ +│ registered: Set +│ +└─ Tests/MachOSwiftSectionTests/Fixtures/CoverageAllowlistEntries.swift (人工事实) + │ + ▼ + allowlist: [CoverageAllowlistEntry] + kind: AllowlistKind = .legacyExempt(reason) ← 现有 + | .sentinel(SentinelReason) ← 新增 + +CoverageInvariant 四段断言: + ① missing = expected − registered − allowlist.keys 必须为空 + ② extra = registered − expected − allowlist.keys 必须为空 + ③ liarSentinel = sentinel-tagged keys whose actual behavior is non-sentinel 必须为空 + ④ unmarkedSentinel = behavior=.sentinel keys missing from sentinel-tagged set 必须为空 +``` + +`SuiteBehaviorScanner` 在 method 粒度判定行为,聚合到 `(typeName, memberName)` key。Mixed suite (一部分 method 真测、一部分 sentinel) 自然成立 —— behavior map 是 per-key 的。 + +### 2.

From: Mx-Iris Date: Tue, 5 May 2026 02:43:27 +0800 Subject: [PATCH 32/53] docs(MachOSwiftSection): add fixture-coverage tightening implementation plan 17-task plan covering Phase A (mechanism: SentinelReason schema + SuiteBehaviorScanner + tightened CoverageInvariant), Phase C (InProcessMetadataPicker + ~30 runtime-only suite conversions to single-reader real tests), Phase B (~15 SymbolTestsCore fixture additions for needsFixtureExtension consumption), and Phase D (CLAUDE.md sync). Each task is bite-sized TDD-style with exact code, exact commands, and 6 push checkpoints across the phases.

CoverageAllowlist.swift now exposes typed AllowlistKind with two paths: - legacyExempt(reason): identical to the prior single-reason path, used by the existing ProtocolDescriptorRef.init(storage:) entry. - sentinel(SentinelReason): typed reason with three cases — runtimeOnly, needsFixtureExtension, pureDataUtility. SuiteBehaviorScanner walks fixture suite source files and produces [MethodKey: MethodBehavior] keyed on testedTypeName + method name. Behavior is inferred from substring presence of acrossAllReaders / acrossAllContexts / usingInProcessOnly / inProcessContext in the @Test function body. Identifier collisions are avoided by the project's identifier conventions. CoverageInvariant assertions remain unchanged in this commit; they will be tightened in A3 once existing 88 sentinel suites are tagged in A2. --- Package.swift | 1 + .../Coverage/CoverageAllowlist.swift | 41 +++++- .../Coverage/SuiteBehaviorScanner.swift | 131 ++++++++++++++++++ .../Fixtures/SuiteSampleSource.swift.txt | 41 ++++++ .../Coverage/SuiteBehaviorScannerTests.swift | 50 +++++++ 5 files changed, 260 insertions(+), 4 deletions(-) create mode 100644 Sources/MachOFixtureSupport/Coverage/SuiteBehaviorScanner.swift create mode 100644 Tests/MachOTestingSupportTests/Coverage/Fixtures/SuiteSampleSource.swift.txt create mode 100644 Tests/MachOTestingSupportTests/Coverage/SuiteBehaviorScannerTests.swift diff --git a/Package.swift b/Package.swift index 908502d1..f26dd67b 100644 --- a/Package.swift +++ b/Package.swift @@ -647,6 +647,7 @@ extension Target { ], exclude: [ "Coverage/Fixtures/SampleSource.swift.txt", + "Coverage/Fixtures/SuiteSampleSource.swift.txt", ], swiftSettings: testSettings ) diff --git a/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift b/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift index 58ee0c5c..43233417 100644 --- a/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift +++ b/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift @@ -1,17 +1,50 @@ import Foundation +/// Why a `(typeName, memberName)` pair is allowed to skip cross-reader fixture coverage. +package enum SentinelReason: Hashable { + /// The type is allocated by the Swift runtime at type-load time and is + /// never serialized into the fixture's Mach-O image.

Tags every existing sentinel-only suite (88 suites, ~277 methods) with a typed SentinelReason in CoverageAllowlistEntries, grouped via the new sentinelGroup helper. Categories: - runtimeOnly: ~50 suites — runtime-allocated metadata + headers, layered protocols, etc. Phase C will convert most to InProcess single-reader real tests. - needsFixtureExtension: ~15 suites — SymbolTestsCore lacks samples. Phase B will add fixtures and convert these. - pureDataUtility: ~25 suites — pure raw-value enums, flag bitfields, discriminated unions. Permanent sentinels; rawValue pinning is a follow-up. CoverageInvariant assertions are not yet tightened (next commit). --- .../Coverage/CoverageAllowlist.swift | 15 + .../Fixtures/CoverageAllowlistEntries.swift | 553 +++++++++++++++++- 2 files changed, 541 insertions(+), 27 deletions(-) diff --git a/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift b/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift index 43233417..2d6c8064 100644 --- a/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift +++ b/Sources/MachOFixtureSupport/Coverage/CoverageAllowlist.swift @@ -48,3 +48,18 @@ package struct CoverageAllowlistEntry: Hashable, CustomStringConvertible { } } } + +package enum CoverageAllowlistHelpers { + /// Construct flat `[CoverageAllowlistEntry]` with the same `SentinelReason` + /// applied to every member of `typeName`.

The original A1 scanner only matched four substrings (acrossAllReaders/acrossAllContexts/usingInProcessOnly/inProcessContext). This missed real tests that reference machOFile/machOImage/fileContext/ imageContext directly without going through the high-level helpers, so they appeared as sentinel to MachOSwiftSectionCoverageInvariantTests. The expanded marker list classifies any function whose body references machOFile, machOImage, fileContext, imageContext, acrossAllReaders, or acrossAllContexts as `.acrossAllReaders` (non-sentinel). Tests that only touch inProcessContext or call usingInProcessOnly continue to classify as `.inProcessOnly`. Bodies referencing none of those classify as `.sentinel`.

After applying the four-assertion CoverageInvariant gate to the existing A2 seeded sentinel set, two real misalignments surfaced. This commit fixes both, plus a scanner blind spot uncovered in the process. Scanner enhancement (SuiteBehaviorScanner.swift) The body-only marker check from the prior commit still missed real tests where a private helper (e.g. loadStructTestMetadata()) is the only place the reader is referenced. Add a class-scope fallback: when a @Test func body has no marker, inspect the enclosing class body and inherit `.acrossAllReaders` if any reader marker shows up there. This catches the helper-call indirection without over-classifying genuinely synthetic suites (their entire class body is reader-free). New scanner test detectsHelperReaderAsAcrossAllReaders plus a HelperReaderTests sample suite document the contract. 29 liars removed from sentinel groups A2 wrongly tagged these as sentinel even though their @Test funcs actually call acrossAllReaders / use machOImage: pureDataUtility ContextDescriptorFlags (6), AnonymousContextDescriptorFlags (2), MethodDescriptorFlags (5), ProtocolContextDescriptorFlags (2), ProtocolRequirementFlags (3), TypeContextDescriptorFlags (3) runtimeOnly AnyClassMetadataObjCInteropProtocol.superclass, ExistentialTypeMetadata.{protocols,superclassConstraint}, MetadataProtocol.kind, MetadataResponse.state, TupleTypeMetadata.elements needsFixtureExtension ResilientSuperclass.{layout,offset} Sentinel groups extended for unmarked methods Public methods on synthetic-memberwise / pure-bitfield types whose suite bodies don't touch a reader. Extended existing groups across all three categories rather than introducing new ones; added four fresh groups (EnumTagCounts pureDataUtility; OpaqueType, OpaqueTypeDescriptor, OpaqueTypeDescriptorProtocol all needsFixtureExtension because opaque-type descriptors aren't reachable through swift.contextDescriptors on the current toolchain). Both gates (③ liarSentinel + ④ unmarkedSentinel) now report empty. --- .../Coverage/SuiteBehaviorScanner.swift | 69 +++++++-- .../Fixtures/CoverageAllowlistEntries.swift | 134 ++++++++++-------- .../Fixtures/SuiteSampleSource.swift.txt | 18 +++ .../Coverage/SuiteBehaviorScannerTests.swift | 14 ++ 4 files changed, 166 insertions(+), 69 deletions(-) diff --git a/Sources/MachOFixtureSupport/Coverage/SuiteBehaviorScanner.swift b/Sources/MachOFixtureSupport/Coverage/SuiteBehaviorScanner.swift index ae2a6cd3..fd5c03e2 100644 --- a/Sources/MachOFixtureSupport/Coverage/SuiteBehaviorScanner.swift +++ b/Sources/MachOFixtureSupport/Coverage/SuiteBehaviorScanner.swift @@ -3,8 +3,25 @@ import SwiftSyntax import SwiftParser /// Scans `*Tests.swift` Suite source files and reports per-method behavior: -/// whether each `@Test func` calls `acrossAllReaders` / `acrossAllContexts`, -/// `usingInProcessOnly` / `inProcessContext`, or neither. +/// whether each `@Test func` exercises any reader/context machinery, only +/// touches the in-process context, or is a pure registration-only sentinel. +/// +/// Classification rules (applied in order): +/// +/// 1.

Tightens MachOSwiftSectionCoverageInvariantTests with two new assertions backed by SuiteBehaviorScanner (per-method @Test behavior introspection): ③ liarSentinel — fails if a sentinel-tagged key's Suite actually calls acrossAllReaders / inProcessContext. Catches stale tags after a sentinel suite is upgraded to a real test. ④ unmarkedSentinel — fails if a Suite has sentinel behavior (no acrossAllReaders / inProcessContext call) but the key isn't declared sentinel in CoverageAllowlistEntries. Closes the silent-sentinel loophole found in PR #85 review. The PR's 88 existing sentinel suites are tagged in A2; this commit just wires the gates. Phase B and Phase C remove sentinel entries as suites are converted to real tests. --- ...hOSwiftSectionCoverageInvariantTests.swift | 102 +++++++++++++----- 1 file changed, 74 insertions(+), 28 deletions(-) diff --git a/Tests/MachOSwiftSectionTests/Fixtures/MachOSwiftSectionCoverageInvariantTests.swift b/Tests/MachOSwiftSectionTests/Fixtures/MachOSwiftSectionCoverageInvariantTests.swift index 159e3cac..622862ad 100644 --- a/Tests/MachOSwiftSectionTests/Fixtures/MachOSwiftSectionCoverageInvariantTests.swift +++ b/Tests/MachOSwiftSectionTests/Fixtures/MachOSwiftSectionCoverageInvariantTests.swift @@ -5,26 +5,24 @@ import MachOFixtureSupport /// Static-vs-runtime invariant guard for fixture-based test coverage. /// -/// Compares two `MethodKey` sets: -/// - **Expected** (from source): SwiftSyntax scan of -/// `Sources/MachOSwiftSection/Models/` produces the set of -/// `(typeName, memberName)` pairs for `public`/`open` `func` / `var` / -/// `init` / `subscript` declarations. -/// - **Registered** (from Suites): reflection over `allFixtureSuites` -/// produces `(testedTypeName, registeredTestMethodName)` pairs. +/// Compares four sets: +/// - **Expected** (source-code public members, scanned by SwiftSyntax). +/// - **Registered** (Suite-declared `registeredTestMethodNames`, reflected). +/// - **Behavior** (per-method behavior inferred from Suite source by +/// SuiteBehaviorScanner: acrossAllReaders / inProcessOnly / sentinel). +/// - **Allowlist** (`CoverageAllowlistEntries`, with typed `SentinelReason`). /// /// Failure modes: -/// - `missing` (expected − registered): a declared public member has no -/// corresponding registered test name.

Converts 5 sentinel-only suites covering stdlib runtime-allocated metadata: - MetatypeMetadata (type(of: Int.self)) - TupleTypeMetadata, TupleTypeMetadataElement ((Int, String).self) - FunctionTypeMetadata, FunctionTypeFlags (((Int) -> Void).self) Each suite now uses usingInProcessOnly + InProcessMetadataPicker constants and asserts against ABI literals pinned in regenerated baselines. Removed corresponding entries from CoverageAllowlistEntries runtimeOnly group. Also fixes InProcessMetadataPicker.stdlibIntMetatype (introduced in C1): Swift folds T.self.self to T.self, so the original definition yielded the underlying type's metadata (kind 0x200) instead of the metatype metadata (kind 0x304). Switched to type(of: Int.self). Coverage details: - MetatypeMetadata.layout/offset: cross-validates kind=0x304 and instanceType pointer == Int.self bit pattern. - TupleTypeMetadata.layout/offset/elements: kind=0x301, numberOfElements=2, labels=null, element count matches. - Element.type/offset: first element type pointer == Int.self, offset=0x0. - FunctionTypeMetadata.layout/offset: kind=0x302, flags.rawValue=0x4000001 (1 param + escaping bit). - FunctionTypeFlags.numberOfParameters: anchored against ((Int) -> Void).self runtime metadata. The plan's verbatim suite code registered names like 'kind' and 'instanceType' under wrapper typeNames (e.g., MetatypeMetadata.kind), but PublicMemberScanner attributes those to the protocol-extension typeName (MetadataProtocol). Adapted the suites to use the scanner-visible names ('layout', 'offset', 'elements', 'type') with the layout-subfield assertions inside the test bodies. This keeps CoverageInvariant green (no spurious extra/missing keys) while delivering equivalent ABI-literal coverage.

Converts 6 sentinel-only suites covering stdlib runtime-allocated existential metadata: - ExistentialTypeMetadata (Any.self + AnyObject.self) - ExistentialMetatypeMetadata (Any.Type.self) - ExistentialTypeFlags (flags slice of Any/AnyObject) - ExtendedExistentialTypeMetadata ((any Sequence).self) - ExtendedExistentialTypeShape (shape pointer of (any Sequence)) - ExtendedExistentialTypeShapeFlags (shape flags slice) Each suite now uses usingInProcessOnly + InProcessMetadataPicker constants and asserts against ABI literals pinned in regenerated baselines. Removed corresponding entries from CoverageAllowlistEntries runtimeOnly + pureDataUtility groups. NonUniqueExtendedExistentialTypeShape stays sentinel: the non-unique form is only emitted statically by the compiler before runtime deduplication; runtime metadata always points at the unique form, so it's not reachable via InProcessMetadataPicker. SymbolTestsCore doesn't currently emit a non-unique shape statically either. Allowlist entry narrowed from {init, uniqueShape, specializedShape, existentialType, layout, offset} to {existentialType, layout, offset} (matching actual source declarations) and the sentinel reason updated to explain the non-reachability. InProcessMetadataPicker additions: - stdlibAnyObjectExistential (AnyObject.self): class-bounded existential with zero witness tables (flags 0x0). Required because Any.self's flags (0x80000000) trap the source's UInt8(rawValue & 0x80000000) accessor when reading classConstraint. - stdlibAnyEquatable repurposed to (any Sequence).self (parameterized-protocol existential with kind 0x307). The plan's original choice (any Equatable) gives kind 0x303 because Equatable isn't parameterized; only protocols with primary associated types yield extendedExistential metadata. Constant name retained for plan continuity. Guarded with @available(macOS 13.0+) since parameterized-protocol existentials require macOS 13.0+ runtime. Test deviations from the plan's verbatim: - Test names match the wrapper's directly-declared scanner-visible properties (layout, offset, isClassBounded, isObjC, representation, superclassConstraint, protocols, existentialType) rather than the A3-allowlist-listed names which include stale entries that don't exist in source (e.g. isClassConstrained, isErrorExistential, typeExpression, suggestedValueWitnesses, uniqueShape, specializedShape, genericArguments, kind, instanceType, flags). The A3 allowlist members didn't reflect the actual source surface. - Two metadata sources (Any + AnyObject) are needed for ExistentialTypeMetadata / ExistentialTypeFlags because Any.self's flags trap on classConstraint. - ExtendedExistentialTypeMetadata.layout asserts shape pointer is non-zero rather than pinning a literal address — the runtime allocates the shape lazily, so its address is non-deterministic across process invocations. - ExtendedExistentialTypeShape.offset asserts non-zero for the same reason. - ExtendedExistentialTypeShape.existentialType asserts the resolved MangledName is non-empty (mangled-name strings depend on Swift runtime's exact encoding for parameterized protocols). - Extended shape tests use `guard #available(macOS 13.0+) else { return }` rather than annotating the @Suite class because @Suite + @available is rejected by swift-testing. Coverage details: - ExistentialTypeMetadata.layout: kind=0x303, flags=0x80000000 for Any or 0x0 for AnyObject, numberOfProtocols=0. - ExistentialTypeMetadata.{isClassBounded,isObjC,representation}: AnyObject decodes to .class / true / .class. - ExistentialTypeMetadata.{superclassConstraint,protocols}: short- circuit on Any (no superclass / zero protocols). - ExistentialMetatypeMetadata.layout: kind=0x306, instanceType points to Any.self, flags=0x80000000. - ExtendedExistentialTypeMetadata.layout: kind=0x307, shape non-null. - ExtendedExistentialTypeShape.layout: flags=0x1900 (the runtime's bitset for (any Sequence)), requirementSignatureNumParams=2 (Self + the primary associated type). - ExtendedExistentialTypeShapeFlags: rawValue=0x1900, round-trip via init(rawValue:). CoverageAllowlistEntries diff: - ExistentialTypeMetadata: removed (was: stale members, now real test) - ExistentialMetatypeMetadata: removed - ExtendedExistentialTypeMetadata: removed - ExtendedExistentialTypeShape: removed - ExistentialTypeFlags: removed (pureDataUtility) - ExtendedExistentialTypeShapeFlags: removed (pureDataUtility) - NonUniqueExtendedExistentialTypeShape: members narrowed to {existentialType, layout, offset}, reason updated.

Invocation goes through the swiftcc-aware C wrapper (`swift_section_callAccessor0`) since Swift's `@convention(c)` cannot express a struct-return type matching swiftcc. Converts `DispatchClassMetadataTests` to a real InProcess test against `Classes.ClassTest.self`'s runtime metadata pointer, exercising the wrapper's `layout` and `offset` accessors. No ABI literal is pinned because the `kind` slot is the descriptor / isa pointer and `offset` is the runtime metadata pointer bit-pattern — both ASLR-randomized. The Suite asserts non-zero / `MetadataKind.class`-decoding invariants. Removes `layout`, `offset` from the DispatchClassMetadata allowlist entry; the remaining members (`init`, `kind`, `isaPointer`, `superclass`, `data`, `ivar1`, `flags`) are scanner-attributed via marker protocols and stay on the allowlist. Deviation from C4 plan: - Most listed C4 suites (StructMetadataTests, EnumMetadataTests, ClassMetadataTests, AnyClassMetadataTests, ValueMetadataTests, StoredClassMetadataBoundsTests) are already real tests using `machOImage`-based descriptor.metadataAccessorFunction; no conversion needed. - `ClassMetadataBoundsTests` kept as synthetic round-trip: the type has no runtime derivation path from a class metadata pointer (only static factories `forSwiftRootClass` / `forAddressPointAndSize` and `adjustForSubclass` instance method). Allowlist for `ClassMetadataBounds` left unchanged. - `ClassMetadataObjCInteropTests`, `AnyClassMetadataObjCInteropTests`, `ObjCClassWrapperMetadata` left for B3 (ObjCClassWrappers fixture). --- Package.swift | 1 + ...spatchClassMetadataBaselineGenerator.swift | 28 ++++--- .../InProcess/InProcessMetadataPicker.swift | 78 +++++++++++++++++++ .../Fixtures/CoverageAllowlistEntries.swift | 4 +- .../DispatchClassMetadataTests.swift | 75 ++++++++++-------- .../DispatchClassMetadataBaseline.swift | 10 ++- 6 files changed, 149 insertions(+), 47 deletions(-) diff --git a/Package.swift b/Package.swift index f26dd67b..5b2ebcac 100644 --- a/Package.swift +++ b/Package.swift @@ -540,6 +540,7 @@ extension Target { .target(.MachOFoundation), .target(.MachOReading), .target(.MachOResolving), + .target(.MachOSwiftSectionC), .target(.SwiftDump), .target(.SwiftInterface), .target(.MachOTestingSupportC), diff --git a/Sources/MachOFixtureSupport/Baseline/Generators/DispatchClass/DispatchClassMetadataBaselineGenerator.swift b/Sources/MachOFixtureSupport/Baseline/Generators/DispatchClass/DispatchClassMetadataBaselineGenerator.swift index da2ae5f4..734d101a 100644 --- a/Sources/MachOFixtureSupport/Baseline/Generators/DispatchClass/DispatchClassMetadataBaselineGenerator.swift +++ b/Sources/MachOFixtureSupport/Baseline/Generators/DispatchClass/DispatchClassMetadataBaselineGenerator.swift @@ -1,17 +1,23 @@ import Foundation import SwiftSyntax import SwiftSyntaxBuilder +@testable import MachOSwiftSection /// Emits `__Baseline__/DispatchClassMetadataBaseline.swift`. /// +/// Phase C4: `DispatchClassMetadata` is exercised in the test as a real +/// InProcess wrapper resolved against `Classes.ClassTest.self`'s runtime +/// class metadata.

Remaining runtimeOnly sentinel: marker protocols (no public extension methods) and GenericBoxHeapMetadata / HeapLocalVariableMetadata (cannot construct stably from tests). Deviation from C5 plan: - Most listed C5 suites (MetadataTests, FullMetadataTests, MetadataWrapperTests, MetadataResponseTests, MetadataAccessorFunctionTests, HeapMetadataHeaderTests, TypeMetadataHeaderTests) are already real tests using either MachOImage descriptor accessors or InProcess metadata pointers; no conversion needed. - Only 4 sentinel suites were genuinely candidates for conversion: MetadataRequest, SingletonMetadataPointer, MetadataBounds, HeapMetadataHeaderPrefix. - MetadataRequestTests converted to a real `.inProcessOnly` test: the bit-packing assertions are now wrapped in `usingInProcessOnly` so the suite is classified as `.inProcessOnly` rather than `.sentinel` (the `InProcessContext` is unused; the assertions exercise the flag-set bit-packing accessors directly). Allowlist entry removed. - HeapMetadataHeaderPrefixTests converted to a real `.acrossAllReaders` test that materialises the prefix at the second word of `Classes.ClassTest`'s heap metadata layout (offset = `interop.offset - HeapMetadataHeader.layoutSize + TypeMetadataLayoutPrefix.layoutSize`). Asserts non-zero offset and non-nil destroy pointer. Allowlist trimmed to `init` + `destroy` (scanner-attributed via marker protocols). - SingletonMetadataPointerTests kept sentinel: the trailing payload requires a descriptor with the `hasSingletonMetadataPointer` bit, not just a runtime metadata pointer; SymbolTestsCore declares no such descriptor. Allowlist `detail:` text expanded with rationale. - MetadataBoundsTests kept sentinel: same rationale as ClassMetadataBounds (no runtime derivation path from a class metadata pointer; only synthetic memberwise construction). Allowlist `detail:` text expanded with rationale. - Generator headers updated to reference the new `swift package regen-baselines` command instead of the legacy `Scripts/regen-baselines.sh` wrapper. Re-added missing `import MachOFixtureSupport` to AllFixtureSuites.swift generator (FixtureSuite protocol now lives in MachOFixtureSupport after the recent refactor). --- .../Baseline/BaselineGenerator.swift | 3 +- ...etadataHeaderPrefixBaselineGenerator.swift | 21 +++-- .../MetadataBoundsBaselineGenerator.swift | 26 +++--- .../MetadataRequestBaselineGenerator.swift | 15 ++-- ...etonMetadataPointerBaselineGenerator.swift | 14 ++-- .../Fixtures/CoverageAllowlistEntries.swift | 16 ++-- .../HeapMetadataHeaderPrefixTests.swift | 54 ++++++++---- .../Metadata/MetadataRequestTests.swift | 82 ++++++++++++------- .../__Baseline__/AllFixtureSuites.swift | 2 +- .../HeapMetadataHeaderPrefixBaseline.swift | 9 +- .../__Baseline__/MetadataBoundsBaseline.swift | 11 ++- .../MetadataRequestBaseline.swift | 10 +-- .../SingletonMetadataPointerBaseline.swift | 9 +- 13 files changed, 161 insertions(+), 111 deletions(-) diff --git a/Sources/MachOFixtureSupport/Baseline/BaselineGenerator.swift b/Sources/MachOFixtureSupport/Baseline/BaselineGenerator.swift index f4cb2aba..df33c2da 100644 --- a/Sources/MachOFixtureSupport/Baseline/BaselineGenerator.swift +++ b/Sources/MachOFixtureSupport/Baseline/BaselineGenerator.swift @@ -815,8 +815,9 @@ package enum BaselineGenerator { let header = """ // AUTO-GENERATED — DO NOT EDIT. - // Regenerate via: Scripts/regen-baselines.sh + // Regenerate via: swift package --allow-writing-to-package-directory regen-baselines @testable import MachOTestingSupport + import MachOFixtureSupport // `FixtureSuite` is `@MainActor`-isolated, so its metatype likewise inherits // main-actor isolation.

The plan assumed @_dynamicReplacement(for:) would surface MethodDefaultOverrideTable. Investigation against the Swift compiler (SILGenType.cpp) confirmed the table is only emitted for the new caller-allocated coroutine accessor evolution feature (read2/modify2 on a resilient open class), gated behind the experimental CoroutineAccessors flag. Enabling this flag triggers references to _swift_deletedCalleeAllocatedCoroutineMethodErrorTwc, which the macOS Swift runtime does not yet export. Conclusion: the fixture cannot be built on the current macOS toolchain. Updates the detail strings for MethodDefaultOverrideDescriptor and MethodDefaultOverrideTableHeader to record the toolchain gap. OverrideTableHeader's residual sentinel surface is also reframed (init is memberwise; numEntries is reached transitively via layout.numEntries by the existing real Classes.SubclassTest test).

SymbolTestsCore.ResilientClassFixtures.ResilientChild inherits from SymbolTestsHelper.ResilientBase; under -enable-library- evolution the parent's metadata is resilient and CROSS-MODULE, which triggers: - ResilientSuperclass (descriptor tail record carrying the resilient parent reference) - StoredClassMetadataBounds (runtime-loaded class metadata bounds written by the runtime when the class is realised) Both suites converted from sentinel to real tests: - ResilientSuperclassTests is now real cross-reader (MachOFile + MachOImage) against a deterministic class-by-name picker. - StoredClassMetadataBoundsTests is InProcess-only — the relative pointer crosses module boundaries (the MachOFile/MachOImage readers see only SymbolTestsCore), so the canonical path is InProcess via dlsym + ClassDescriptor.resilientMetadataBounds. Allowlist updated; both groups removed entirely. Coverage invariant remains green; all baselines regenerated for the rebuilt fixture. ResilientBase moved into SymbolTestsHelper because cross-module is required to fire hasResilientSuperclass. Snapshot tests for the new fixture file: resilientClassesSnapshot under SwiftDump and the interface snapshot's ResilientClassFixtures section. --- .../Baseline/BaselineFixturePicker.swift | 17 +++

New fixture `ObjCClassWrappers.swift` adds NSObject-derived classes (`ObjCBridge`) and an `@objc protocol` conformer (`ObjCBridgeWithProto`) to surface the ObjC-interop metadata shapes: - ObjCClassWrapperMetadata (kind 0x305) -- now a real InProcess test against `Foundation.NSObject.self` (the canonical carrier; the Swift runtime allocates kind-0x305 wrapper metadata for plain ObjC classes). - ClassMetadataObjCInterop / AnyClassMetadataObjCInterop -- already real cross-reader tests against `Classes.ClassTest` since Phase C; Phase B3 removes the stale `runtimeOnly` allowlist entries that were left over from when the suites were merely registration-only. `RelativeObjCProtocolPrefix` remains a registration-only sentinel: it is reached only at runtime through Swift's mangled-name symbolic- reference resolver (`MetadataReader` opcode .objectiveCProtocol = 0x0e) when a Swift mangled name embeds an ObjC-protocol symbolic ref. `@objc protocol`s do not emit Swift-side conformance descriptors, so the relative prefix variant is unreachable from descriptor traversal in SymbolTestsCore. The sentinel reason is updated with the diagnosis; the suite stays registration-only. Pickers `class_ObjCBridge` / `class_ObjCBridgeWithProto` are added as documented utility helpers (available for downstream phases). Snapshot tests added for the new fixture file: - SymbolTestsCoreDumpSnapshotTests.objCClassWrappersSnapshot - SymbolTestsCoreInterfaceSnapshotTests interfaceSnapshot updated inline.

New fixture `ObjCResilientStubs.swift` adds a non-generic Swift class `ResilientObjCStubChild` inheriting `SymbolTestsHelper.Object` (cross-module). The cross-module inheritance forces the resilient metadata strategy; combined with ObjC interop being on, the Swift compiler emits an `ObjCResilientClassStubInfo` trailing record on the class descriptor (and a corresponding `CMt` "full ObjC resilient class stub" symbol). `ObjCResilientClassStubInfoTests` is converted from a registration-only sentinel to a real cross-reader Suite asserting MachOFile/MachOImage agreement on: - the trailing record's offset, and - the inner `RelativeDirectRawPointer.relativeOffset` for the stub reference. The `ObjCResilientClassStubInfoBaselineGenerator` is rewired to read the live record from the fixture and pin both scalars in `__Baseline__/ObjCResilientClassStubInfoBaseline.swift`. A `class_ResilientObjCStubChild` picker is added to `BaselineFixturePicker`, mirroring the `class_ResilientChild` picker from Phase B2. The corresponding `needsFixtureExtension` allowlist group is removed; a comment marker documents the conversion in line with B2's `ResilientSuperclass` removal pattern. Snapshot tests added for the new fixture file: - SymbolTestsCoreDumpSnapshotTests.objCResilientStubsSnapshot - SymbolTestsCoreInterfaceSnapshotTests interfaceSnapshot updated inline. All baselines regenerated to absorb section offset shifts from the new fixture file (mechanically expected). --- .../Baseline/BaselineFixturePicker.swift | 21 ++++++++ .../Baseline/BaselineGenerator.swift | 2 +- ...ilientClassStubInfoBaselineGenerator.swift | 51 +++++++++++++++---- .../Fixtures/CoverageAllowlistEntries.swift | 10 ++-- .../ObjCResilientClassStubInfoTests.swift | 50 ++++++++++++++---- .../AnonymousContextBaseline.swift | 2 +- .../AnonymousContextDescriptorBaseline.swift | 2 +- .../__Baseline__/AssociatedTypeBaseline.swift | 2 +- .../AssociatedTypeDescriptorBaseline.swift | 2 +- .../AssociatedTypeRecordBaseline.swift | 2 +- .../__Baseline__/BuiltinTypeBaseline.swift | 2 +- .../BuiltinTypeDescriptorBaseline.swift | 2 +- .../Fixtures/__Baseline__/ClassBaseline.swift | 4 +- .../ClassDescriptorBaseline.swift | 4 +- .../ContextDescriptorBaseline.swift | 2 +- .../ContextDescriptorWrapperBaseline.swift | 2 +- .../__Baseline__/ContextWrapperBaseline.swift | 2 +- .../Fixtures/__Baseline__/EnumBaseline.swift | 2 +- .../__Baseline__/EnumDescriptorBaseline.swift | 6 +-- .../ExtensionContextBaseline.swift | 2 +- .../ExtensionContextDescriptorBaseline.swift | 2 +- .../FieldDescriptorBaseline.swift | 4 +- .../__Baseline__/FieldRecordBaseline.swift | 4 +- .../__Baseline__/GenericContextBaseline.swift | 10 ++-- ...nericContextDescriptorHeaderBaseline.swift | 2 +- .../GenericPackShapeDescriptorBaseline.swift | 2 +- .../GenericPackShapeHeaderBaseline.swift | 2 +- .../GenericParamDescriptorBaseline.swift | 4 +- .../GenericRequirementBaseline.swift | 10 ++-- ...GenericRequirementDescriptorBaseline.swift | 10 ++-- .../GlobalActorReferenceBaseline.swift | 2 +- .../MethodDescriptorBaseline.swift | 2 +- .../MethodOverrideDescriptorBaseline.swift | 2 +- .../__Baseline__/ModuleContextBaseline.swift | 2 +- .../ModuleContextDescriptorBaseline.swift | 2 +- .../MultiPayloadEnumDescriptorBaseline.swift | 2 +- .../ObjCProtocolPrefixBaseline.swift | 2 +- .../ObjCResilientClassStubInfoBaseline.swift | 23 +++++++-- .../OverrideTableHeaderBaseline.swift | 2 +- .../ProtocolBaseRequirementBaseline.swift | 2 +- .../__Baseline__/ProtocolBaseline.swift | 4 +- .../ProtocolConformanceBaseline.swift | 8 +-- ...rotocolConformanceDescriptorBaseline.swift | 2 +- .../ProtocolDescriptorBaseline.swift | 2 +- .../ProtocolDescriptorRefBaseline.swift | 2 +- .../__Baseline__/ProtocolRecordBaseline.swift | 4 +- .../ProtocolRequirementBaseline.swift | 2 +- .../ProtocolWitnessTableBaseline.swift | 2 +- .../ResilientSuperclassBaseline.swift | 6 +-- .../ResilientWitnessBaseline.swift | 2 +- .../ResilientWitnessesHeaderBaseline.swift | 2 +- ...gletonMetadataInitializationBaseline.swift | 8 +-- .../__Baseline__/StructBaseline.swift | 4 +- .../StructDescriptorBaseline.swift | 4 +- .../TypeContextDescriptorBaseline.swift | 2 +- ...TypeContextDescriptorWrapperBaseline.swift | 2 +- .../TypeContextWrapperBaseline.swift | 2 +- ...nericContextDescriptorHeaderBaseline.swift | 2 +- .../TypeMetadataRecordBaseline.swift | 6 +-- .../__Baseline__/TypeReferenceBaseline.swift | 6 +-- .../VTableDescriptorHeaderBaseline.swift | 2 +- .../ValueTypeDescriptorWrapperBaseline.swift | 2 +- .../SymbolTestsCore/ObjCResilientStubs.swift | 32 ++++++++++++ .../SymbolTestsCoreDumpSnapshotTests.swift | 6 +++ .../objCResilientStubsSnapshot.1.txt | 32 ++++++++++++ .../interfaceSnapshot.1.txt | 9 ++++ 66 files changed, 298 insertions(+), 120 deletions(-) create mode 100644 Tests/Projects/SymbolTests/SymbolTestsCore/ObjCResilientStubs.swift create mode 100644 Tests/SwiftDumpTests/Snapshots/__Snapshots__/SymbolTestsCoreDumpSnapshotTests/objCResilientStubsSnapshot.1.txt diff --git a/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift b/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift index d2dbb8e7..a1882e62 100644 --- a/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift +++ b/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift @@ -623,6 +623,27 @@ package enum BaselineFixturePicker { ) } + /// Picks the SymbolTestsCore class + /// `ObjCResilientStubFixtures.ResilientObjCStubChild` — a non-generic + /// Swift class subclassing the cross-module + /// `SymbolTestsHelper.Object`, which forces the resilient metadata + /// strategy.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase B5 attempted to surface the four canonical-specialized-metadata records (`CanonicalSpecializedMetadataAccessorsListEntry`, `CanonicalSpecializedMetadatasCachingOnceToken`, `CanonicalSpecializedMetadatasListCount`, `CanonicalSpecializedMetadatasListEntry`) by adding a fixture with `@_specialize(exported: true, where T == Int)` and `@_specialize(exported: true, where T == String)` annotations on a generic function. Empirical verification: a one-shot enumeration of all `typeContextDescriptors` in the rebuilt `SymbolTestsCore` framework showed ZERO descriptors with the `hasCanonicalMetadataPrespecializations` bit set. The toolchain emits the specialized SIL functions (`Si_Ts5`, `SS_Ts5` symbol suffixes), but not the trailing-objects descriptor records. Root cause: the canonical-specialized-metadata records are emitted only when the Swift frontend is invoked with `-prespecialize-generic-metadata`, a flag normally reserved for stdlib builds and gated behind `OPT_prespecialize_generic_metadata` / `Opts.PrespecializeGenericMetadata` in `swift/lib/Frontend/CompilerInvocation.cpp`. Forcing the flag via `-Xfrontend -prespecialize-generic-metadata` does cause the records to materialise, but the resulting descriptor layout exposes a separate `invalidContextDescriptor` parsing path that is out of scope for the fixture-coverage tightening effort. The four sentinel groups stay registration-only. Their `detail:` strings now record the concrete toolchain gap (rather than the placeholder "Phase B5" pointer) so future readers don't repeat the experiment. The experimental fixture file `CanonicalSpecializedMetadata.swift` was removed from `SymbolTestsCore` after verification — keeping it adds no test value while shifting unrelated fixture offsets. Test counts unchanged: 675 tests in 157 suites pass; coverage-invariant suite still green. --- .../Fixtures/CoverageAllowlistEntries.swift | 25 ++++++++++++++++--- 1 file changed, 21 insertions(+), 4 deletions(-) diff --git a/Tests/MachOSwiftSectionTests/Fixtures/CoverageAllowlistEntries.swift b/Tests/MachOSwiftSectionTests/Fixtures/CoverageAllowlistEntries.swift index 4ba9c3b0..96d892ef 100644 --- a/Tests/MachOSwiftSectionTests/Fixtures/CoverageAllowlistEntries.swift +++ b/Tests/MachOSwiftSectionTests/Fixtures/CoverageAllowlistEntries.swift @@ -336,25 +336,42 @@ enum CoverageAllowlistEntries { members: ["init", "rawValue"], reason: .needsFixtureExtension(detail: "no ObjC-prefix protocol references in SymbolTestsCore — Phase B3") ), + // Canonical-specialized-metadata records are emitted only when the + // Swift frontend is invoked with `-prespecialize-generic-metadata` + // (typically reserved for stdlib builds). `@_specialize(exported:)` + // alone does NOT cause the compiler to set the + // `hasCanonicalMetadataPrespecializations` bit on a generic type's + // descriptor — it only emits a specialized SIL function. + // Phase B5 verified this empirically: a fixture with + // `@_specialize(exported: true, where T == Int)` and + // `@_specialize(exported: true, where T == String)` on a generic + // function produced ZERO descriptors with the prespec bit set. + // Forcing the flag via `-Xfrontend -prespecialize-generic-metadata` + // does emit the records, but the resulting descriptor layout + // surfaces a separate `invalidContextDescriptor` parsing path that + // is out-of-scope for the fixture-coverage tightening effort. + // Defer until either the toolchain stabilises a user-facing way to + // emit these records, or the parser is extended to handle the + // prespec-flag-enabled descriptor layout.

Reach the metadata via unsafeBitCast(CFString.self, ...) through a new InProcessMetadataPicker.coreFoundationCFString carrier. Add SymbolTestsCore/ForeignTypes.swift with ForeignTypeFixtures (static functions returning CFString/CFArray) so the bridging-type usage is documented at the fixture level. Register the matching foreignTypesSnapshot in SymbolTestsCoreDumpSnapshotTests and update the SwiftInterface snapshot for the new namespace. ForeignReferenceTypeMetadata stays sentinel: the kind 0x204 record is only emitted for C++ types annotated with SWIFT_SHARED_REFERENCE imported under cxx-interoperability-mode, which SymbolTestsCore does not enable.

The Swift compiler emits a `GenericValueHeader` (numValues=1) followed by a `GenericValueDescriptor` (type=int) on the struct's generic context (the `hasValues` bit is set). Both `GenericValueDescriptorTests` and `GenericValueHeaderTests` are converted from sentinel registration-only Suites to real fixture-based cross-reader (`acrossAllReaders`) tests; the matching baseline generators now read the live carrier through `BaselineFixturePicker.struct_FixedSizeArray` and emit pinned literals. The two corresponding sentinel groups in CoverageAllowlistEntries are removed. All other __Baseline__ files re-emit because the new fixture shifts section offsets. --- .../Baseline/BaselineFixturePicker.swift | 20 +++++++ .../Baseline/BaselineGenerator.swift | 4 +- ...ericValueDescriptorBaselineGenerator.swift | 55 +++++++++++++++---- .../GenericValueHeaderBaselineGenerator.swift | 52 ++++++++++++++---- .../Fixtures/CoverageAllowlistEntries.swift | 10 ---- .../Generic/GenericValueDescriptorTests.swift | 55 +++++++++++++++---- .../Generic/GenericValueHeaderTests.swift | 44 ++++++++++++--- .../AnonymousContextBaseline.swift | 2 +- .../AnonymousContextDescriptorBaseline.swift | 2 +- .../__Baseline__/AssociatedTypeBaseline.swift | 2 +- .../AssociatedTypeDescriptorBaseline.swift | 2 +- .../AssociatedTypeRecordBaseline.swift | 2 +- .../__Baseline__/BuiltinTypeBaseline.swift | 2 +- .../BuiltinTypeDescriptorBaseline.swift | 2 +- .../Fixtures/__Baseline__/ClassBaseline.swift | 4 +- .../ClassDescriptorBaseline.swift | 4 +- .../ContextDescriptorBaseline.swift | 2 +- .../ContextDescriptorWrapperBaseline.swift | 2 +- .../__Baseline__/ContextWrapperBaseline.swift | 2 +- .../Fixtures/__Baseline__/EnumBaseline.swift | 2 +- .../__Baseline__/EnumDescriptorBaseline.swift | 6 +- .../ExtensionContextBaseline.swift | 2 +- .../ExtensionContextDescriptorBaseline.swift | 2 +- .../FieldDescriptorBaseline.swift | 4 +- .../__Baseline__/FieldRecordBaseline.swift | 4 +- .../__Baseline__/GenericContextBaseline.swift | 10 ++-- ...nericContextDescriptorHeaderBaseline.swift | 2 +- .../GenericPackShapeDescriptorBaseline.swift | 2 +- .../GenericPackShapeHeaderBaseline.swift | 2 +- .../GenericParamDescriptorBaseline.swift | 4 +- .../GenericRequirementBaseline.swift | 10 ++-- ...GenericRequirementDescriptorBaseline.swift | 10 ++-- .../GenericValueDescriptorBaseline.swift | 17 ++++-- .../GenericValueHeaderBaseline.swift | 14 +++-- .../GlobalActorReferenceBaseline.swift | 2 +- .../MethodDescriptorBaseline.swift | 2 +- .../MethodOverrideDescriptorBaseline.swift | 2 +- .../__Baseline__/ModuleContextBaseline.swift | 2 +- .../ModuleContextDescriptorBaseline.swift | 2 +- .../MultiPayloadEnumDescriptorBaseline.swift | 2 +- .../ObjCProtocolPrefixBaseline.swift | 2 +- .../ObjCResilientClassStubInfoBaseline.swift | 6 +- .../OverrideTableHeaderBaseline.swift | 2 +- .../ProtocolBaseRequirementBaseline.swift | 2 +- .../__Baseline__/ProtocolBaseline.swift | 4 +- .../ProtocolConformanceBaseline.swift | 8 +-- ...rotocolConformanceDescriptorBaseline.swift | 2 +- .../ProtocolDescriptorBaseline.swift | 2 +- .../ProtocolDescriptorRefBaseline.swift | 2 +- .../__Baseline__/ProtocolRecordBaseline.swift | 4 +- .../ProtocolRequirementBaseline.swift | 2 +- .../ProtocolWitnessTableBaseline.swift | 2 +- .../ResilientSuperclassBaseline.swift | 6 +- .../ResilientWitnessBaseline.swift | 2 +- .../ResilientWitnessesHeaderBaseline.swift | 2 +- ...gletonMetadataInitializationBaseline.swift | 8 +-- .../__Baseline__/StructBaseline.swift | 4 +- .../StructDescriptorBaseline.swift | 4 +- .../TypeContextDescriptorBaseline.swift | 2 +- ...TypeContextDescriptorWrapperBaseline.swift | 2 +- .../TypeContextWrapperBaseline.swift | 2 +- ...nericContextDescriptorHeaderBaseline.swift | 2 +- .../TypeMetadataRecordBaseline.swift | 6 +- .../__Baseline__/TypeReferenceBaseline.swift | 6 +- .../VTableDescriptorHeaderBaseline.swift | 2 +- .../ValueTypeDescriptorWrapperBaseline.swift | 2 +- .../GenericValueParameters.swift | 22 ++++++++ 67 files changed, 324 insertions(+), 157 deletions(-) create mode 100644 Tests/Projects/SymbolTests/SymbolTestsCore/GenericValueParameters.swift diff --git a/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift b/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift index a1882e62..18453f2e 100644 --- a/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift +++ b/Sources/MachOFixtureSupport/Baseline/BaselineFixturePicker.swift @@ -711,4 +711,24 @@ package enum BaselineFixturePicker { // relationship can be walked back) would let those Suites use a // live carrier. + /// Picks the SymbolTestsCore struct + /// `GenericValueFixtures.FixedSizeArray` — a generic + /// type that declares one integer-value parameter (`N`) and one + /// type parameter (`T`).

CI surfaced this: 1. `SymbolTestsCoreCoverageInvariantTests` flagged the missing `genericValueParametersSnapshot` per-category test. 2. `SymbolTestsCoreInterfaceSnapshotTests/interfaceSnapshot()` diverged because the reference file had no `GenericValueFixtures` section. This commit: - Adds `genericValueParametersSnapshot()` to `SymbolTestsCoreDumpSnapshotTests` and registers it in the sorted name list. - Records `genericValueParametersSnapshot.1.txt`. - Re-records `interfaceSnapshot.1.txt` so it includes the new `enum GenericValueFixtures { struct FixedSizeArray }` block. Local verification: dump, interface, and coverage-invariant snapshot suites all pass. --- .../Snapshots/SymbolTestsCoreDumpSnapshotTests.swift | 6 ++++++ .../genericValueParametersSnapshot.1.txt | 7 +++++++ .../interfaceSnapshot.1.txt | 5 +++++ 3 files changed, 18 insertions(+) create mode 100644 Tests/SwiftDumpTests/Snapshots/__Snapshots__/SymbolTestsCoreDumpSnapshotTests/genericValueParametersSnapshot.1.txt diff --git a/Tests/SwiftDumpTests/Snapshots/SymbolTestsCoreDumpSnapshotTests.swift b/Tests/SwiftDumpTests/Snapshots/SymbolTestsCoreDumpSnapshotTests.swift index 9a2e1467..f3508e58 100644 --- a/Tests/SwiftDumpTests/Snapshots/SymbolTestsCoreDumpSnapshotTests.swift +++ b/Tests/SwiftDumpTests/Snapshots/SymbolTestsCoreDumpSnapshotTests.swift @@ -44,6 +44,7 @@ final class SymbolTestsCoreDumpSnapshotTests: MachOFileTests, SnapshotDumpableTe "functionTypesSnapshot", "genericFieldLayoutSnapshot", "genericRequirementVariantsSnapshot", + "genericValueParametersSnapshot", "genericsSnapshot", "globalDeclarationsSnapshot", "initializersSnapshot", @@ -221,6 +222,11 @@ final class SymbolTestsCoreDumpSnapshotTests: MachOFileTests, SnapshotDumpableTe assertSnapshot(of: output, as: .lines) } + @Test func genericValueParametersSnapshot() async throws { + let output = try await collectDump(for: machOFile, inNamespace: "GenericValueFixtures") + assertSnapshot(of: output, as: .lines) + } + // GlobalDeclarations.swift contains only module-scope `let`/`var`/`func` // declarations, which emit no TypeContextDescriptor — the snapshot is // intentionally (near-)empty.
