sjaakola 754872e2c4 recording GTID checkpoint before leaving commit monitor

This fix relates to github bug #607, where wrong wsrep XID store order
caused assert in innodb wsrep checkpointing.
Wrong store order happened after certification failure, where the failing
transaction rushed to record wsrep XID bebfore the offending applier
transaction. This race condition was possible because the applier released
first commit monitor and after that recorded wsrep XID as innodb checkpoint.

The fix for this issue forces all wsrep GTID checkpointing to happen
inside commit monitor. Hence, a fix for this wsrep-lib routine was needed,
to align with the checkpoinnting logic, and record checkpoint just before
leaving commit monitor.

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
