The autopackage binary packaging framework

The autopackage project is building a cross-distribution software packaging system. The software is being built by this group of programmers. The autopackage FAQ explains some of the project goals:

For users: it makes software installation on Linux easier. If a project provides an autopackage, you know it can work on your distribution. You know it'll integrate nicely with your desktop and you know it'll be up to date, because it's provided by the software developers themselves. You don't have to choose which distro you run based on how many packages are available.

[autopackage] For developers: it's software that lets you create binary packages for Linux that will install on any distribution, can automatically resolve dependencies and can be installed using multiple front ends, for instance from the command line or from a graphical interface. It lets you get your software to your users quicker, easier and more reliably. It immediately increases your user base by allowing people with no native package to run your software within seconds.

Autopackage aims to improve on some of the weaknesses of packaging systems such as RedHat's RPM, the RPM Package Manager: "What RPM is not good at is non-core packages, ie programs available from the net, from commercial vendors, magazine coverdisks and so on. This is the area that autopackage tackles."

The use of autopackage involves the package command line utility, or GTK2 and Qt versions of the Manger application. The GUI interface is designed to resemble the Windows InstallShield application. One-click package installation that is similar to Linspire's commercial CNR (click and run) package system makes installations simple. The user interface vision document explains some of the interface guidelines. The how to use document presents a quick tour of the system, and the autopackage screen shots show the software in action.

The autopackage system uses executable package files with the .package suffix, the package format has been designed with multiple distribution support as a primary feature. Automatic dependency resolution is being addressed by the use of Luau, the Lib Update/AutoUpdate Suite.

Issues that need addressing with autopackage include dealing with the upgrading of applications installed by other package management systems, securely managing the signing of packages in a decentralized package distribution environment, lack of a common desktop Linux platform definition, and support for platforms other than X86 and X86-64.

The success of the project may largely depend on its adoption by independent software applications designers. If a critical mass of applications is reached, end users will have sufficient motive to install the software, and the distribution vendors will have motivation to include the system in their base systems. Applications developers wishing to create .package files should review the Packager QuickStart document. A limited number of packages are currently listed on the autopackage downloads page.

Autopackage fills a software distribution niche between distribution-specific packaged software and source code that requires building by the end user. This seems like an area that is fertile for development, developers of lesser-known software applications would likely see their code more widely used if they provided .package files.

Version 1.0.6 of autopackage was announced this week, it includes bug fixes and other improvements.

ZODB 3.4.1 final released

Final version 3.4.1 of ZODB, the Zope Object Database, is out. "There have been many bugfixes in various areas since ZODB 3.4. In addition, optional ZEO client cache tracing was badly broken with the introduction of multiversion concurrency control (MVCC) in ZODB 3.3, and ZODB 3.4.1 is the first attempt to repair that."
