Summary: Remove the SyncPoint usage in the destructor of PosixEnv as none of any active tests is using it. SyncPoint is a test-only utility class, and it's a static varible. As a result, using SyncPoint in the destructor of PosixEnv will make default Env depends on SyncPoint. Removing such dependency could solve the problem crash issue only reproducable in Mac environment. Test Plan: OPT=-DTRAVIS V=1 make -j4 check on Mac environment Reviewers: sdong, anthony Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D54333
RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.
