Historia

costan d9a9e02edf leveldb: Add tests for CL 170769101. This also removes std::unique_ptr introduced in CL 170738066, because it's C++11-only, and the open source version still supports older versions at the moment. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=170876919		7 lat temu
