PHP 5.3.1 packages for Debian “Lenny” : they’re here!

The official announcement

A few days ago, the PHP Group released PHP 5.3.1 :

The PHP development team would like to announce the immediate availability of PHP 5.3.1. This release focuses on improving the stability of the PHP 5.3.x branch with over 100 bug fixes, some of which are security related. All users of PHP are encouraged to upgrade to this release.

Security Enhancements and Fixes in PHP 5.3.1:

The Dotdeb changes

On the Debian side, some changes were made :

  • the packages are now patched with the official Suhosin patch.
  • beside the apache2, apache2filter, CGI and CLI flavours, the FPM one has now its own dedicated package, named “php5-fpm”. It will allow you to have greater performances and a lot of more features on a CGI-style installation (FYI, an init script, a config file and a nginx config sample are provided).

How to install?

Because migrating from PHP 5.2. to PHP 5.3 can break some applications, here is the Dotdeb release policy :

  • PHP 5.2 is still the default branch for Debian Lenny for some weeks/months. PHP 5.3 packages are kept on a separate repository.
  • PHP 5.3 will be the default branch for the upcoming Debian Squeeze (mid-2010)

Then , to install PHP 5.3 on your Debian “Lenny” box, just add these two entries in your /etc/apt/sources.list :

deb http://php53.dotdeb.org stable all
deb-src http://php53.dotdeb.org stable all

Now launch your favorite commands (apt-get update && apt-get upgrade) to upgrade your box.

In case you enjoy this new release, feel free to donate or to take a look at my whishlist… Xmas is coming 😉

MySQL 5.1.40 is available for Debian “Lenny” and “Etch” with InnoDB-plugin support

MySQL 5.1.40 is now available on Dotdeb for Debian 5.0 “Lenny” / Debian 4.0 “Etch” in amd64/i386 flavours.

As usual, this maintenance release fixes a lot of bugs (please read the Changelog for more details).

Please note that the packaging is a little bit different from the official Debian packaging, to include the InnoDB plugin in the mysql-server-5.1 package instead of in the libmysqlclient-dev one. This plugin replaces the built-in InnoDB support and has many advantages :

  • fast index creation,
  • data compression,
  • new row formats,
  • new file formats,
  • performance and scalability enhancements…

You can easily enable it by uncommenting to lines in the /etc/mysql/my.cnf configuration file and then restart your MySQL server :

Editing my.cnf to enable the InnoDB plugin support

Please read carefully the InnoDB plugin documentation and backup your data before activating this beta quality feature!

To avoid the same negative feedbacks as about PHP 5.2.10, a lot of debug and changes has been made :
