Percona XtraBackup 2.3.6 is now available

Percona XtraBackup 2.4.5

Percona XtraBackup 2.3.6Percona announces the release of Percona XtraBackup 2.3.6 on November 29, 2016. Downloads are available from our download site or Percona Software Repositories.

Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, Percona XtraBackup drives down backup costs while providing unique features for MySQL backups.

This release is the current GA (Generally Available) stable release in the 2.3 series.

New Features
  • Percona XtraBackup now supports SHA256 passwords. Using the SHA256 algorithm requires either SSL encrypted connection, or using public key encryption for password exchange which is only available when both client and server are linked with OpenSSL.
  • Percona XtraBackup now supports Command Options for Secure Connections.
  • NOTE: Due to xbcrypt format changes, backups encrypted with this Percona XtraBackup version will not be recoverable by older versions.
Bugs Fixed:
  • Fixed intermittent assertion failures that were happening when Percona XtraBackup couldn’t correctly identify server version. Bug fixed #1568009.
  • Safe slave backup algorithm performed too short delays between retries which could cause backups to fail on a busy servers. Bug fixed #1624473.
  • Fixed new compilation warnings with GCC 6. Bug fixed #1641612.
  • xbcrypt was not setting the Initialization Vector (IV) correctly (and thus is was not using an IV). This was causing the same ciphertext to be generated across different runs (for the same message/same key). The IV provides the extra randomness to ensure that the same ciphertext is not generated across runs. Bug fixed #1643949.
  • Backup would still succeed even if XtraBackup would fail to write the metadata. Bug fixed #1623210.
  • xbcloud now supports EMC ECS Swift API Authorization requests. Bugs fixed #1638017 and #1638020 (Txomin Barturen).
  • Percona XtraBackup would fail to backup MariaDB 10.2 with the unsupported server version error message. Bug fixed #1602842.

Other bugs fixed: #1639764 and #1639767.

Release notes with all the bugfixes for Percona XtraBackup 2.3.6 are available in our online documentation. Bugs can be reported on the launchpad bug tracker.

Percona Server 5.6.33-79.0 is now available

percona server 5.6.33-79.0

percona server 5.6.33-79.0Percona announces the release of Percona Server 5.6.33-79.0 on October 18th, 2016. Download the latest version from the Percona web site or the Percona Software Repositories.

Based on MySQL 5.6.33, including all the bug fixes in it, Percona Server 5.6.33-79.0 is the current GA release in the Percona Server 5.6 series. Percona Server is open-source and free – this is the latest release of our enhanced, drop-in replacement for MySQL. Complete details of this release are available in the 5.6.33-79.0 milestone on Launchpad.

New Features:
  • Percona Server has implemented support for per-column VARCHAR/BLOB compression for the XtraDB storage engine. This also features compression dictionary support, to improve compression ratio for relatively short individual rows, such as JSON data.
  • A new TokuDB tokudb_dir_per_db option has been introduced to address two TokuDB shortcomings, the renaming of data files on table/index rename, and the ability to group data files together within a directory that represents a single database. This feature is disabled by default.
Bugs Fixed:
  • After fixing bug #1540338, system table engine validation check is no longer skipped for tables that don’t have an explicit ENGINE clause in a CREATE TABLE statement. If MySQL upgrade statements are replicated, and slave does not have the MyISAM set as a default storage engine, then the CREATE TABLE mysql.server statement would attempt to create an InnoDB table and fail because mysql_system_tables.sql script omitted explicit engine setting for this table. Bug fixed #1600056.
  • Audit Log Plugin malformed record could be written after audit_log_flush was set to ON in ASYNC and PERFORMANCE modes. Bug fixed #1613650.
  • A race condition between HandlerSocket and server shutdown could lead to a server stall if shutdown was issued immediately after HandlerSocket startup. Bug fixed #1617198.
  • HandlerSocket could access freed memory on startup. Bug fixed #1617998.
  • Workloads with statements that take non-transactional locks (LOCK TABLES, global read lock, and similar) could have caused deadlocks when running under Thread Pool with high priority queue enabled and thread_pool_high_prio_mode set to transactions. Fixed by placing such statements into the high priority queue even with the above thread_pool_high_prio_mode setting. Bugs fixed #1619559 and #1374930.
  • Fixed memory leaks in Audit Log Plugin. Bug fixed #1620152 (upstream #71759).
  • Server could crash due to a glibc bug in handling short-lived detached threads. Bug fixed #1621012 (upstream #82886).
  • QUERY_RESPONSE_TIME_READ and QUERY_RESPONSE_TIME_WRITE were returning QUERY_RESPONSE_TIME table data if accessed through a name that is not full uppercase. Bug fixed #1552428.
  • Fixed memory leaks in HandlerSocket. Bug fixed #1617949.
  • KILL QUERY was not behaving consistently and it would hang in some cases. Bug fixed #1621046 (upstream #45679).
  • Cipher ECDHE-RSA-AES128-GCM-SHA256 was listed in the list of supported ciphers but it wasn’t supported. Bug fixed #1622034 (upstream #82935).
  • Successful doublewrite recovery was showed as a warning in the error log. Bug fixed #1622985.
  • Variable query_cache_type couldn’t be set to 0 if it was already set to that value. Bug fixed #1625501 (upstream #69396).
  • LRU manager thread could run too long on a server shutdown, causing a server crash. Bug fixed #1626069.
  • tokudb_default was not recognized by Percona Server as a valid row format. Bug fixed #1626206.
  • InnoDB ANALYZE TABLE didn’t remove its table from the background statistics processing queue. Bug fixed #1626441 (upstream #71761).
  • Upstream merge for #81657 to 5.6 was incorrect. Bug fixed #1626936 (upstream #83124).
  • Fixed multi-threaded slave thread leaks that happened in case of thread create failure. Bug fixed #1619622 (upstream #82980).
  • Shutdown waiting for a purge to complete was undiagnosed for the first minute. Bug fixed #1616785.
  • Unnecessary InnoDB change buffer merge attempts are now skipped upon reading disk pages of non-applying types. Bug fixed #1618393 (upstream #75235).

Other bugs fixed: #1614439, #1614949, #1616392 (upstream #82798), #1624993 (#736), #1613647, #1626002 (upstream #83073), #904714, #1610102, #1610110, #1613663, #1613728, #1613986, #1614885, #1615959, #1615970, #1616333, #1616404, #1616768, #1617150, #1617216, #1617267, #1618478, #1618811, #1618819, #1619547, #1619572, #1620583, #1622449, #1622456, #1622977, #1623011, #1624992 (#1014), #1625176, #1625187, #1626500, #1628417, #964, and #735.
