MySQL-wsrep 5.7.31-25.23 Release Notes

Codership is pleased to announce a new GA release of Galera Cluster for MySQL 5.7, consisting of MySQL-wsrep 5.7.31 and wsrep API version 25.

This release incorporates all changes up to MySQL 5.7.31.

Galera Cluster 5.7 is now available as targeted packages and package repositories for Debian, Ubuntu, CentOS, RHEL, OpenSUSE and SLES. Obtaining packages using a package repository removes the need to download individual files and facilitates the deployment and upgrade of Galera nodes.

This and future releases will be available from https://www.galeracluster.com.

The latest version of MySQL-wsrep 5.7 for FreeBSD is available in the FreeBSD Ports Collection.

The source repositories and bug tracking are now on https://github.com/codership/mysql-wsrep.

Notable fixes in MySQL-wsrep since the last binary release by Codership (5.7.30-25.22).

• Binary tarball package is compiled with OpenSSL 1.1.1g.

• Deadlock between DDL and applying transaction was fixed.

• Fix for the following security vulnerability CVE-2020-15180.

End of Life Notice:

This is the last release for Debian Jessie and openSUSE 15.0.

Known issues with this release:

• Server cannot be started using 'service' command on Debian Stretch.

• SST between 5.6 and 5.7 nodes is not supported

• InnoDB tablespaces outside of the data directory are not supported, as they may not be copied over during SST

• Compilation with DTrace enabled may fail, so -DENABLE_DTRACE=:BOOL=OFF may be given to cmake to disable DTrace

Changes to Repositories Structure

With the new release the repository structure is changed to allow for existence of all of the wsrep-patched mysql versions currently supported: 5.5 through 5.7. Thus the repository layout requires from the user to adjust his or her repository configuration to accomodate those changes. In order to have the WSREP and Galera library installed, one would need to add the following repositories: 1. Galera-3 repository for galera library: e.g. https://releases.galeracluster.com/galera-3/<ldist>/ 2. Corresponding mysql-wsrep repository: e.g. https://releases.galeracluster.com/mysql-wsrep-<mversion>/<ldist> here: ldist is Linux or BSD distribution (Ubuntu, Centos) and mversion is MySQL version, i.e. 5.5, 5.6, 5.7

How To Install

Repositories contain dummy or meta packages, called mysql-wsrep- which are convenience packages for installation of the corresponding version of WSREP. One can install the whole suite by running, for example: apt-get install mysql-wsrep-5.7 galera-3
