test(extraction): dense-header regression guard for UE class recovery (#1160)#1206
Merged
Conversation
…#1160) The integration tests that shipped with #1158 use inputs too small to trigger the tree-sitter class_specifier collapse, so they pass with OR without the fix (verified: 0/3 reproduce on the pre-fix build) — only the offset-preserving unit tests actually guard the behavior. This adds a real guard: a ~240-in-body-macro reflected class (the density of the real CharacterMovementComponent.h) plus a UENUM whose values carry mid-line UMETA. Asserting the decorated members and the enum are extracted flips false->true across the three blank passes — verified the same assertions FAIL on the pre-fix source (2a06d9a) and PASS on the fix. The full class collapse is emergent from real engine-header content that can't be shipped (Unreal source is EULA-licensed); this reproduces the recoverable-member signal the collapse leaves, which regresses if any of blankCppAnnotationMacroCalls / blankCppApiPrefixMacros / blankCppInlineAnnotationMacros is reverted.

Follow-up to #1158. The integration tests that landed with that fix use inputs too small to trigger the tree-sitter
class_specifiercollapse, so they pass with or without the fix (verified: 0/3 reproduce on the pre-fix build) — only the offset-preserving unit tests actually guarded the behavior.This adds a genuine guard: a ~240-in-body-macro reflected class (the density of the real
CharacterMovementComponent.h) plus aUENUMwhose values carry mid-lineUMETA. It asserts the decorated members (Compute0, a middle one, and the last) and the enum are extracted — signals that flip false → true across the three blank passes.Verified both directions: the same assertions fail on the pre-fix source (
2a06d9a, before #1158) and pass on the fix — so reverting any ofblankCppAnnotationMacroCalls/blankCppApiPrefixMacros/blankCppInlineAnnotationMacrosregresses at least one assertion.The full class collapse is emergent from real engine-header content that can't be shipped (Unreal source is EULA-licensed); this reproduces the recoverable-member signal the collapse leaves. Test-only; full extraction suite 578/578.
