What this solves
Adds a regression test for object rest destructuring of a dynamic import. With the build-time
__vitePreloadrewrite,import('./m').then(({ a, ...rest }) => ...)dropped the sibling exports fromrest(it was nested one level deeper,{ rest: {...} }), silently producing wrong output. The underlying bug and fix are in rolldown: rolldown/rolldown#9976.The new case in
playground/dynamic-importimports a module with several named exports via object-rest destructuring and asserts thatrestkeeps its sibling keys. It fails against the buggy build output and passes once Vite picks up the fixed rolldown.Notes for reviewers
The test exercises the build-mode
__vitePreloadpath (the nativeviteBuildImportAnalysisPluginfromrolldown/experimental). It turns green after the rolldown fix (rolldown/rolldown#9976) is released and therolldowndependency is bumped.
