Chrooted environments are known to greatly improve system and application security by providing them with a higher degree of isolation. The objective is to separate as much as possible from other executables and resources the runtime environment of an application so that if a hacker get access to it,the rest of the system is not compromised. This technic is commonly used with MySQL.

Traditionally, the chrooting applies at the file system level, by creating a separated and minimal operating system disk-image.  The operation consists in creating a set of directories (such a /chroot/etc, /chroot/tmp, /chroot/var/tmp, /chroot/usr/local/mysql etc.) and duplicate a minimal number of binary and configuration files into this new directory tree. After setting the right permissions on the new directories, the chrootuid utility is used to execute the application in the restricted environment. …

The latest MySQL 5.5 milestone release offers support for an ANSI/ISO standard feature called the SIGNAL syntax. You can use this syntax inside stored routines (including triggers) to raise an error condition which can be used to invoke specific error handling, or otherwise abort the stored routine. In addition, you can use the SIGNAL syntax to convey information about what went wrong, which may be used by the caller to handle the error.

I have written about MySQL data entry validation procedures in the past. At the time, MySQL did not support any proper means to raise an error condition inside a stored routine, and …

The European Commission has now got a lot of emails! It seems they even have to block some (at least GMail) just to keep their mail server alive. Thank you, all, for helping out, it is working.

In this blog I will explain why these promises are not very helpful, even if they show that even Oracle is a little bit concerned now.

The first thing is of course that
