Summary: Use db mutex to protect the execution of Version::GetColumnFamilyMetaData() called in DBImpl::GetColumnFamilyMetaData(). Without mutex, GetColumnFamilyMetaData() races with MarkFilesBeingCompacted() for access to FileMetaData::being_compacted. Other than mutex, there are several more alternatives. - Make FileMetaData::being_compacted an atomic variable. This will make FileMetaData non-copy-able. - Separate being_compacted from FileMetaData. This requires re-organizing data structures that are already used in many places. Test Plan (dev server): ``` make check ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/6056 Differential Revision: D18620488 Pulled By: riversand963 fbshipit-source-id: 87f89660b5d5e2ab4ef7962b7b2a7d00e346aa3b |
