Summary: This ports `folly::DistributedMutex` into RocksDB. The PR includes everything else needed to compile and use DistributedMutex as a component within folly. Most files are unchanged except for some portability stuff and includes. For now, I've put this under `rocksdb/third-party`, but if there is a better folder to put this under, let me know. I also am not sure how or where to put unit tests for third-party stuff like this. It seems like gtest is included already, but I need to link with it from another third-party folder. This also includes some other common components from folly - folly/Optional - folly/ScopeGuard (In particular `SCOPE_EXIT`) - folly/synchronization/ParkingLot (A portable futex-like interface) - folly/synchronization/AtomicNotification (The standard C++ interface for futexes) - folly/Indestructible (For singletons that don't get destroyed without allocations) Pull Request resolved: https://github.com/facebook/rocksdb/pull/5642 Differential Revision: D16544439 fbshipit-source-id: 179b98b5dcddc3075926d31a30f92fd064245731 |
