Levi Tamasi cbf5f3be43 Do not move VersionEdit into AtomicGroupReadBuffer (#6400)
Summary:
https://github.com/facebook/rocksdb/pull/6383 surfaced an issue with
`VersionSet`/`ReactiveVersionSet` and `AtomicGroupReadBuffer::AddEdit`
(which was added in https://github.com/facebook/rocksdb/pull/5411):
`AddEdit` moves the `VersionEdit` passed to it into `replay_buffer_`,
however, the client `VersionSet` classes keep using it afterwards. This
*seemed to* work before the refactoring but it really did not: since
`VersionEdit` used to have a user-declared destructor, no move
constructor/move assignment operator was generated, and the `move` in
`AddEdit` was really a copy. The patch makes the copy explicit. Note: it
should be possible to rework this logic so that we can get away
with the move but for now, this should fix the issue.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6400

Test Plan:
`make check`
`make analyze`

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/
