Development Release: Slackware Linux 13.0 RC2

Patrick Volkerding has announced that Slackware "current", the distribution's development branch, has reached release candidate 2 status: "Hi folks! We're going to call this set of updates RC2. There are still README files to be handled (that's the nature of documentation, I guess), as well as some other things remaining on the TODO list, but X seems pretty stable now, and it seems like a release soon would be in order so that we can march right back into development territory with -current again soon. Enjoy, and let us know about any problems you run into!" Find more information in the changelog. Slackware Linux 13.0 RC2 comes with Linux kernel 2.6.29.6, GCC 4.3.3, X.Org Server 1.6.3 and KDE 4.2.4. As always, there are no official ISO images to download, but those interested in helping with last-minute testing can get these unofficial installation DVDs and upgrade to RC2 with slackpkg: slackware-current-04_Aug_2009-DVD.iso (1,743MB, MD5), slackware64-current-04_Aug_2009-DVD.iso (1,678MB, MD5).

PostgreSQL 8.4 Released: Now Easier to Use than Ever

Posted on 2009-07-01
Posted by press@postgresql.org

The PostgreSQL Global Development Group has released version 8.4, continuing the rapid development of the world's most advanced open source database. This release contains an abundance of enhancements to make administering, querying, and programming of PostgreSQL databases easier than ever before. Our development team has spent 16 months adding over two hundred improvements to all aspects of database functionality, helping every PostgreSQL user in small or large ways.

Many of the changes in PostgreSQL 8.4 are new or improved administration and monitoring tools and commands. Each user has their own favorite features which will make day-to-day work with PostgreSQL easier and more productive for them. Among the most popular enhancements are:

Parallel Database Restore, speeding up recovery from backup up to 8 times
Per-Column Permissions, allowing more granular control of sensitive data
Per-database Collation Support, making PostgreSQL more useful in multi-lingual environments
In-place Upgrades through pg_migrator (beta), enabling upgrades from 8.3 to 8.4 without extensive downtime
New Query Monitoring Tools, giving administrators more insight into query activity
Greatly Reduced VACUUM Overhead through the Visibility Map
New Monitoring Tools for current queries, query load and deadlocks

Version 8.4 also makes data analysis easier through the advanced ANSI SQL2003 features of windowing functions, common table expressions and recursive queries. Enhancements to stored procedures, such as default parameters and variadic parameters, make database server programming simpler and more compact. Of course, there are also performance improvements included in this version.

Download version 8.4 today and start enjoying using PostgreSQL even more!

PostgreSQL 8.4 Release Candidate 1 Now Available Posted on 2009-06-14 Posted by press@postgresql.org

Final release of PostgreSQL 8.4 comes much closer today with our first Release Candidate. Now, we count on all of the PostgreSQL users and developers worldwide to test this Release Candidate to make sure that it is stable, reliable, secure and high-performance enough to be called an official PostgreSQL release. Please download 8.4 RC1 today and test it with your applications.

Beta testing information page and download links

Note that no Windows MSI installer will be released for this Release Candidate. Windows users are advised to use the One-Click Installer instead.

Several of the issues patched in this release relate to pg_migrator, the new beta in-place upgrade tool for upgrading PostgreSQL databases. Please test migrating a copy of your 8.3 databases to 8.4 and report further issues with pg_migrator, especially issues related to Additional Modules (contrib). pg_migrator will release version RC1 soon which will be compatible with 8.4 RC1, and you can get it on pgFoundry.

This Release Candidate also includes a number of changes to handling of NULL inputs to internal functions in order to prevent denial-of-service exploits. First, the general internal_in() function is now NONSTRICT in order to trap NULL errors for debugging. Second, several internal functions in our Additional Modules have been marked STRICT to lock them down, especially several GiST index functions and pg_freespacemap. Please check for unanticipated side-effects of this more secure policy for internal functions against your application, especially if you use PostgreSQL plug-ins like GIS and BLAST.

Other specific items fixed since Beta2 Include:

-- Fix FreeBSD Kerberos support
-- Fix row ordering on scrollable and WITH HOLD cursors
-- Make datetime precision in INFORMATION_SCHEMA comply with the standard
-- Normalize input for INTERVAL subtypes
-- Prevent double-escaping of XML strings, and eliminate XML crash bug
-- Fix DBlink default encoding issue
-- Reverted incompatible change to Intarray operators
-- Fix estimated row count statistic for partial vacuums
-- Add support for the SQL/MED API to DBlink
-- Fix a GIN index corruption issue
-- Improve coding of pluralization in translatable strings
-- Correct initialization of Perl library support to support Perl 5.10
-- Fix several issues with rotation of pg_standby log segments
-- Fix handling of LIKE '%_' syntax
-- Multiple minor fixes to ECPG interface

For a complete list of fixes, see our Git mirror

We rely on our community of users to ensure that PostgreSQL continues to be the most bug-free SQL database in the industry. This means we need your testing and bug reports as soon as possible.

MySQL 5.4 Released ( April 22, 2009 )

Sun Microsystems has released MySQL 5.4, a new version of the popular open source database. MySQL 5.4 includes performance and scalability improvements enabling the InnoDB storage engine to scale up to 16-way x86 servers and 64-way CMT servers. MySQL 5.4 also includes new subquery optimizations and JOIN improvements, resulting in 90% better response times for certain queries (see www.mysql.com/benchmarks). These performance and scalability gains are transparent and don't require any additional application or SQL coding to take advantage of them.

According to Sun's Karen Tegan Padir, "Without any modifications to your applications, MySQL 5.4 will transparently increase the performance and scalability of your applications, to enable them to scale under more demanding user and data processing loads. MySQL 5.4 is also better suited for scale-up deployments on SMP systems."

MySQL 5.4 features include:

• Scalability improvements -- these fixes allow the InnoDB storage engine to scale up to 16-way x86 servers and 64-way CMT servers, more than doubling its previous capability;
• Subquery optimizations -- improves the performance of analytic query operations, with some subqueries now executing in a fraction of the time compared to previous MySQL versions;
• New query algorithms -- utilizes main memory to speed up the execution time of multi-way joins, especially for MySQL Cluster because the number of round-trips between the server and cluster nodes is minimized;
• Improved stored procedures -- enables more robust error management through the implementation of the SIGNAL/RESIGNAL functions, so applications can more easily rely on stored procedures for business logic;
• Improved prepared statements -- Output parameters will now be supported in prepared statements, which increases their functionality;
• Improved Information Schema -- provides more metadata access to parameters and data return types that stored procedures use, which allows much more information to be made available for developers using connectors such as ODBC and JDBC;
• Improved DTrace support -- improves diagnostics and troubleshooting capabilities for MySQL on the Solaris Operating System.

MySQL 5.4 will be generally available for a wide variety of hardware and software platforms, including Red Hat Enterprise Linux, SuSE Enterprise Linux, Microsoft Windows, Sun Solaris 10 Operating System, Mac OS X, Free BSD, HP-UX, IBM AIX, IBM i5/OS and other Linux distributions.

The preview version of MySQL 5.4 is currently available for download at www.mysql.com/5.2 for 64-bit versions of the Linux and Solaris 10 Operating Systems. Based on community feedback, an estimated release date for a general available version will be announced later this year.
