Yueh-Hsuan Chiang 1369f015ee Only initialize the ThreadStatusData when necessary.
Summary:
Before this patch, any function call to ThreadStatusUtil might automatically initialize and register the thread status data.  However, if it is the user-thread making this call, the allocated thread-status-data will never be released as such threads are not managed by rocksdb.

In this patch, I remove the automatic-initialization part.  Thread-status data is only initialized and uninitialized in Env during the thread creation and destruction.

Test Plan:
db_test
thread_list_test
listener_test

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Build Status

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.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
