Daniele Sciascia 2da6e4894e Unnecessary adopt/start transaction in rollback_fragment()

This patch changes the handling of a rollback fragment so that
the high_priority_service adopts and starts a new transaction only
if fragment removal has to be performed.
When no fragment removal happens, starting a new transaction is
unnecessary: a dummy write set is logged instead and the transaction
is not cleaned up properly in DBMS side.

Introduction

Project name: wsrep-lib - Integration library for WSREP API

The purpose of this project is to implement C++ wrapper for wsrep API with additional convenience for transaction processing.

This project will abstract away most of the transaction state management required on DBMS side and will provide simple C++ interface for key set population, data set population, commit processing, write set applying etc.

Build Instructions

In order to build the library, run

cmake . make

Build Requirements

C++ compiler (g++ 5.4 or later recommended)
CMake version 2.8 or later
The following Boost libraries are required if the unit tests and the sample program is compiled
- Unit Test Framework
- Program Options
