sdong 57096ab13e Fix a bug that crashes the service when write buffer manager fails to insert to block cache (#6619)
Summary:
https://github.com/facebook/rocksdb/issues/6247 reports that when write buffer manager fails to insert the dummy entry to block cache, null pointer is still stored and used to release the handle and cause corruption. Fix the bug by not releasing it with null handle.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6619

Test Plan: Add a unit test that fails without the fix.

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

Linux/Mac Build Status Windows Build status PPC64le 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 especially 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/
