Summary: compaction history is stored in manifest files. Preserve all of them in db_stress would help debugging. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6142 Test Plan: Run db_stress and observe that manifest files are preserved. Run whole crash_test and see how DB directory looks like.
