Redis 2.8.9

Redis 2.8.9 has been released on April 22nd 2014, bringing the HyperLogLog data structure…

You can read more about it in this blog post.
Beside this great announcement, the “Sorted Set” data type has now support for lexicographic range queries, check the new commands ZRANGEBYLEX, ZLEXCOUNT and ZREMRANGEBYLEX, which are documented at http://redis.io.

The upgrade urgency is low because only new features were introduced, no bugs were fixed.

The packages are now available for both Debian 7.0 “Wheezy” and Debian 6.0 “Squeeze” on both amd64 and i386 architectures.

About the “mysql_connect(): Headers and client library minor version mismatch” warning

After having MySQL 5.6.17 published, some users complained about a warning thrown by their PHP applications :

PHP Warning: mysql_connect(): Headers and client library minor version mismatch. Headers:50535 Library:50617

In fact, this could happen with any application linked to libmysqlclient18 in a certain version (php5-mysql from Dotdeb is linked to the 5.5.35 version from the stock Debian distribution) when connecting to a MySQL server in another version (5.6.17 in our case). The warning is thrown by libmysqlclient18 itself. And this is just a warning, there is no reason why any bad behavior would happen in that case.

Of course, I could build php5-mysql against the latest libmysqlclient18 (5.6.17), but it would lead to very bad issues, such as duplicate symbols or segfaults when PHP is loaded with other MySQL-linked modules from the stock Debian distribution (those are linked to libmysqlclient18 5.5.35). For example : mod_php5 + Apache + mod_auth_mysql would crash.

If this this warning really annoys you, feel free to install php5-mysqlnd instead of php5-mysql :

  • it’s a drop-in replacement
  • it’s not linked against any libmysqlclient library
  • it won’t throw any irrelevant warning about version mismatch
  • it has a lot of benefits. See http://www.php.net/mysqlnd for more info

I hope this helps.

MySQL 5.6.17 for Wheezy

After months of work in (slow) progress, I’m glad to announce that packages of MySQL 5.6.17 are now available for Debian 7.4 “Wheezy” on both amd64 and i386 architectures.

This is our first major release of the MySQL 5.6 branch, so be very careful when upgrading your boxes : backup your data first, keep a spare/delayed MySQL slave… And be sure to know in details what’s new in MySQL 5.6 :

  • A better Optimizer
  • InnoDB great new features : online DDL, split kernel mutex, multi-threaded purge, separate flush thread
  • New NoSQL-style memcached APIs
  • Partitioning improvements for querying and managing huge tables
  • Replication now supports multi-threaded slaves, GTID and checksums
  • More data is available through the PERFORMANCE_SCHEMA.
  • …

Of course, feedbacks are welcome, as usual.

By the way, sorry for that delay. Among other reasons, I had to deal with the Oracle/MariaDB/Percona – and now WebscaleSQL – dilemma. It’s still not concluded, since MariaDB is now well integrated in Debian Sid and that its 10.x has been declared as GA a few days ago. Stay tuned, some more announcement might be made in the next few weeks on the Dotdeb side.

Enjoy! And if you want to show your support, follow this link… 🙂
