Update Center Toolkit 2.3 Build 35 Available

The Update Center 2 development team is pleased to announce the availability of build 35 (download) of the Update Center Toolkit. This build resolves 22 defects and contains 7 enhancements beyond the previous build.  Two of the major modifications for this build are support for the AIX operating system and inclusion of a pkg(5) drop that brings in a new transport layer based on the cURL library.The pkg(5) drop is based on build 118 of OpenSolaris with some additional fixes.  The intent is to resynchronize with the pkg(5) gate several additional times before development on 2.3 is concluded.

Feature development for the 2.3 release is now mostly done, and the remaining builds are intended to fix defects.

Road to AIX Support: First Build Milestone for pkg(5)

Yesterday, August 11, 2009, the Image Packaging System, pkg(5), was compiled and run for the first time on IBM's AIX® 6.1 operating system. All of the API unit tests ran successfully, and 69 of the CLI tests passed. Since I don't have root access on the AIX system being used, the other CLI tests were not expected to pass. AIX support for the command line interfaces is one of the features in the Update Center 2.3 toolkit.

The hardest part about porting pkg(5) to AIX has been to assemble the build environment that is needed to compile the software, especially without root access.  Although there are some RPMs available with some of the tools for AIX, these require root access to install.  That's one of the nice things about pkg(5) packaging is that it supports user images that do not require root access. Compilation of pkg(5) requires Python, Mercurial, a C compiler, setuputils, pyXML, simplejson, patch, cURL,  OpenSSL, and tidy. This list and the instructions for performing the build have been recorded on a project wiki page.

Once the build environment was assembled, modifications to only four files (nine lines) were needed to accomplish the initial port. These changes consisted of modifying the build and test scripts and the utility for getting a canonical operating system name to recognize 'aix' as a valid platform. Work still remains to complete more thorough testing and debugging, packaging of pkg(5) into the toolkit for AIX, and making sure other parts of the toolkit such as the Java API are supported on AIX, but this is a big first step.

With the addition of AIX in the 2.3 release, this expands the multi-platform support for the Image Package System to 5 major platforms (Solaris, Linux, Mac/OS, Windows, and AIX).
