Summary
Fixes #8799
When a barrel module uses the
import { a } from './a'; export { a }pattern (import-then-export) alongside a local export likeexport default b, importing the local export requires the barrel to execute. However, the lazy barrel optimization incorrectly treated the shared import record for./athe same as a dedicated re-export record (export { a } from './a'), giving it an empty specifier set. This causedato not be properly loaded, breaking the barrel's execution.The fix introduces an
IsReExportOnlyflag onImportRecordMetato distinguish dedicated re-export records (export { .. } from '..',export * as ns from '..') from shared import records (import { a } from '..'; export { a }). When a barrel has local exports and needs to execute, only dedicated re-export records use empty specifiers — shared import records are loaded with their full specifiers since we cannot statically determine whether their bindings are used by the barrel's own code.
