Dotdeb packages of Redis for Debian 6.0 “Squeeze” have been updated to version 2.2.2. Here are the release notes.

Let me introduce Redis… Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets. You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set. In order to achieve its outstanding performance, Redis works with an in-memory dataset. Depending on your use case, you can persist it either by dumping the dataset to disk every once in a while, or by appending each command to a log. ...

MySQL 5.1.55 packages are now available on Dotdeb : for Debian 6.0 “Squeeze” and Debian 5.0 “Lenny” for the amd64 and i386 architectures As usual, please read the Changelog of this maintainance release before upgrading. Note 1 : the Pinba storage engine for MySQL has been rebuilt against MySQL 5.1.55 (Squeeze only) Note 2 : Maatkit has been updated to 7284 Note 3 : if you had issues with loading the InnoDB plugin on Squeeze, your feedback is welcome (post a comment below). ...

Today is a great day for the Debian community : Debian Squeeze has been released. After 24 months of constant development, the Debian Project is proud to present its new stable version 6.0 (code name Squeeze). Debian 6.0 is a free operating system, coming for the first time in two flavours. Alongside Debian GNU/Linux, Debian GNU/kFreeBSD is introduced with this version as a technology preview. The website of the Debian project also got a facelift. Please visit it for more information. ...

Do you know Pinba? It’s a great tool and you really should use it on your LAMP platform. Pinba is a realtime monitoring/statistics server for PHP using MySQL as a read-only interface. It accumulates and processes data sent over UDP by multiple PHP processes and displays statistics in a nice human-readable form of simple " reports", also providing read-only interface to the raw data in order to make possible generation of more sophisticated reports and stats. ...

I just released PHP 5.3.5 packages for Debian 6.0 (a.k.a “Squeeze”), with some changes against the Lenny’s ones : the packaging process has been improved : dependencies were cleaned up, PHP tests are now displayed, libtool 2.2 is now supported (thanks to the Debian team for their precious work) 3 new useful extensions have been packaged : gearman, phpredis and xhprof (without its interface files) With these new packages, Dotdeb’s support for Squeeze is still experimental, but almost complete. Some more packages could be added in a near future : ...

A few days after releasing PHP 5.3.4 and PHP 5.2.16, the PHP group announced an important security update with PHP 5.3.5 and PHP 5.2.17 : This release resolves a critical issue, reported as PHP bug #53632 and CVE-2010-4645, where conversions from string to double might cause the PHP interpreter to hang on systems using x87 FPU registers. The problem is known to only affect x86 32-bit PHP processes, regardless of whether the system hosting PHP is 32-bit or 64-bit. You can test whether your system is affected by running this script from the command line. ...

After PHP 5.3.4 has been released by the PHP Group and after the corresponding Suhosin patch has been published by Stefan Esser, the PHP 5.3.4 packages for Debian “Lenny” 5.0 are now available on Dotdeb. Thanks for your patience. Follow these instructions if you’re installing them for the first time. And as usual, please read the full announcement and the Changelog before upgrading. Happy new year! ...

PHP 5.2.16 has been released by the PHP Group a few days after PHP 5.2.15 (fixing an open_basedir issue). It is now available on Dotdeb for your Debian “Lenny” servers. This maintainance release marks the end of support for PHP 5.2. You are strongly encouraged to upgrade to PHP 5.3 (read this migration guide). Please read PHP 5.2.15 and 5.2.16 release announcements and the full Changelog before upgrading.

MySQL 5.1.54 packages are now available on Dotdeb in amd64/i386 flavours for Lenny and Squeeze. As usual, please read the Changelog of this maintainance release before upgrading. Now, about MySQL 5.5 (I was asked on Twitter or in the comments here), it will be available on Dotdeb as soon as it is in Debian Sid or experimental. Please be patient. If you don’t need some 5.5 specific features, such as semi-sync replication, and if you just need to boost your InnoDB performances, you really should take a look at your /etc/mysql/my.cnf file and enable the InnoDB plugin. ...
