New Product Releases

New Release of MySQL 5.1.24 (Release Candidate)

We are proud to present to you the MySQL Server 5.1.24-rc release, a new "release candidate" version of the popular open source database. Changes include:

Please note that the Federated engine is not built into the MySQL 5.1.24 RC release binaries, but is scheduled to return in the next release, which will be MySQL 5.1.25. The reasons for Federated's omission in 5.1.24 RC includes various quality and timing issues that unfortunately could not be avoided, and we apologize for any inconvenience this has caused.
Windows Installer: Important Change: The data directory now defaults to the Windows Common App Data Folder (on Windows XP, this is ...\All Users\Application Data; on Vista, it is ProgramData). (Bug#34593)
Replication: Introduced the slave_exec_mode system variable to control whether idempotent or strict mode is used for replication conflict resolution. Idempotent mode suppresses duplicate-key, no-key-found, and some other errors, and is needed for circular replication, multi-master replication, and some other complex replication setups when using MySQL Cluster. Strict mode is the default. (Bug#31609)

New Release of MySQL Connector/.NET 5.0.9 (GA)

MySQL Connector/Net 5.0.9, a new version of the all-managed .NET driver for MySQL has been released. This release is an update to the existing production-quality 5.0 series. We plan for this to be the last release in the 5.0 series. We will only be updating the 5.0 product in the event a "data-loss" type bug is discovered. We encourage all new products to use the new 5.1 product. Changes include:

added implementation of MySqlCommandBuilder methods QuoteIdentifier and UnquoteIdentifier (Bug #35492)
Fixed problem where fields that were blobs but did not include the BLOB flag were treated as binary when they should have been treated as text. (Bug #30233)
Changed from using Array.Copy to Buffer.BlockCopy in MySqlDataReader.GetBytes. This helps with memory usage as we expect the source and destination arrays to not be overlapping. (Bug #31090)

Article: How the MySQL Enterprise Upgrade Advisor Helps DBAs Avoid Being Bitten by Known Bugs

Rob Young

In an effort to provide DBAs with a belt-and-suspenders support and alert system and to further help take the guesswork out of deciding which version of the MySQL server they should be running, MySQL Enterprise now provides the new Upgrade Advisor. The premise is simple; the Upgrade Advisor provides monitoring for specific security and crash inducing bugs that affect current versions of the MySQL Community or Enterprise Server running in an Enterprise Monitor protected environment.

PlanetMySQL Blog: MySQL Proxy: Rollbacked Transactions

Jan Kneschke

If you use a transactional storage engine in MySQL like InnoDB some of your transaction may be terminated by the storage engine because of deadlocks. Sadly it is a bit tricky to see what has led to the deadlock. SHOW ENGINE INNODB STATUS gives only a very minimal look into the state when it happened.

With the proxy and a little script we can track what happened in all open transactions before the deadlock happened. A classic example is the cross-over deadlock:
