Percona XtraDB Cluster 5.7.14-26.17 GA New Features

This is a list of the most important features introduced in Percona XtraDB Cluster 5.7 compared to version 5.6:

  • PXC Strict Mode saves your workload from experimental and unsupported features.
  • Support for monitoring Galera Library instruments and other wsrep instruments as part of Performance Schema.
  • Support for encrypted tablespaces in Multi-Master Topology, which enables Percona XtraDB Cluster to wire encrypted tablespace to new booting node.
  • Compatibility with ProxySQL, including a quick configuration script.
  • Support for monitoring Percona XtraDB Cluster nodes using Percona Monitoring and Management
  • More stable and robust operation with MySQL and Percona Server version 5.7.14, as well as Galera 3.17 compatibility. Includes all upstream bug fixes, improved logging and more.
  • Simplified packaging for Percona XtraDB Cluster to a single package that installs everything it needs, including the Galera library.
  • Support for latest Percona XtraBackup with enhanced security checks.
Bug Fixes
  • Fixed crash when a local transaction (such as EXPLAIN or SHOW) is interrupted by a replicated transaction with higher priority (like ALTER that changes table structure and can thus affect the result of the local transaction).
  • Fixed DONOR node getting stuck in Joined state after successful SST.
  • Fixed error message when altering non-existent table with pxc-strict-mode enabled.
  • Fixed path to the directory in percona-xtradb-cluster-shared.conf.
  • Fixed setting of seqno in grastate.dat to -1 on clean shutdown.
  • Fixed failure of asynchronous TOI actions (like DROP) for non-primary nodes.
  • Fixed replacing of my.cnf during upgrade from 5.6 to 5.7.
Security Fixes
  • CVE-2016-6662
  • CVE-2016-6663
  • CVE-2016-6664

For more information, see this blog post.

Other Improvements

Percona Server 5.7.14-7 is now available

percona server 5.7.14-7Percona announces the GA release of Percona Server 5.7.14-7 on August 23, 2016. Download the latest version from the Percona web site or the Percona Software Repositories.

Based on MySQL 5.7.14, including all the bug fixes in it, Percona Server 5.7.14-7 is the current GA release in the Percona Server 5.7 series. Percona’s provides completely open-source and free software. Find release details in the 5.7.14-7 milestone at Launchpad.

New Features:
Bugs Fixed:
  • Fixed potential cardinality 0 issue for TokuDB tables if ANALYZE TABLE finds only deleted rows and no actual logical rows before it times out. Bug fixed #1607300 (#1006, #732).
  • TokuDB database.table.index names longer than 256 characters could cause a server crash if background analyze table status was checked while running. Bug fixed #1005.
  • PAM Authentication Plugin would abort authentication while checking UNIX user group membership if there were more than a thousand members. Bug fixed #1608902.
  • If DROP DATABASE would fail to delete some of the tables in the database, the partially-executed command is logged in the binlog as DROP TABLE t1, t2, ... for the tables for which drop succeeded. A slave might fail to replicate such DROP TABLE statement if there exist foreign key relationships to any of the dropped tables and the slave has a different schema from the master. Fix by checking, on the master, whether any of the database to be dropped tables participate in a Foreign Key relationship, and fail the DROP DATABASE statement immediately. Bug fixed #1525407 (upstream #79610).
  • PAM Authentication Plugin didn’t support spaces in the UNIX user group names. Bug fixed #1544443.
  • Due to security reasons ld_preload libraries can now only be loaded from the system directories (/usr/lib64, /usr/lib) and the MySQL installation base directory.
  • In the client library, any EINTR received during network I/O was not handled correctly. Bug fixed #1591202 (upstream #82019).
  • SHOW GLOBAL STATUS was locking more than the upstream implementation which made it less suitable to be called with high frequency. Bug fixed #1592290.
  • The included .gitignore in the percona-server source distribution had a line *.spec, which means someone trying to check in a copy of the percona-server source would be missing the spec file required to build the RPMs. Bug fixed #1600051.
  • Audit Log Plugin did not transcode queries. Bug fixed #1602986.
  • If the changed page bitmap redo log tracking thread stops due to any reason, then shutdown will wait for a long time for the log tracker thread to quit, which it never does. Bug fixed #1606821.
  • Changed page tracking was initialized too late by InnoDB. Bug fixed #1612574.
  • Fixed stack buffer overflow if --ssl-cipher had more than 4000 characters. Bug fixed #1596845 (upstream #82026).
  • Audit Log Plugin events did not report the default database. Bug fixed #1435099.
  • Canceling the TokuDB Background ANALYZE TABLE job twice or while it was in the queue could lead to server assertion. Bug fixed #1004.
  • Fixed various spelling errors in comments and function names. Bug fixed #728 (Otto Kekäläinen).
  • Implemented set of fixes to make PerconaFT build and run on the AArch64 (64-bit ARMv8) architecture. Bug fixed #726 (Alexey Kopytov).
Other bugs fixed:

#1542874 (upstream #80296), #1610242, #1604462 (upstream #82283), #1604774 (upstream #82307), #1606782, #1607359, #1607606, #1607607, #1607671, #1609422, #1610858, #1612551, #1613663, #1613986, #1455430, #1455432, #1581195, #998, #1003, and #730.
