NEW: Solaris Package Companion v0.9

Today, I am proud to announce the release of version 0.9 of the Solaris Package Companion. This new version is primary based upon a set of patches provided by Jerome Blanchet that provided support for the collection and processing of reverse dependency information ("R" entries in a package's depend(4)) file) as well as enhanced processing and display of platform specific packages. Thank you, Jerome!

As is my tradition when a bug is found, I try and publish a little something extra as a mea cupla. Due to limited "free time", the "mea culpa" enhancement this time is quite minor but worth mentioning anyway. In past versions, there was no interface to change the information collection rules of the tool. If you wanted to disable the collection of certain types of information (such as package names or dependencies) you had to go into the code and change the relevent COLLECT_ variable. No longer. The defaults are still the same, but now the tool will honor variable settings originating from the shell or command line as follows:

$ env COLLECT_NAMES=0 ./spc-v0.9.ksh -r /tmp/myrepository -i -l

Note that the COLLECT_ variables are only used during the creation of a repository. Not a big enhancement, but one none the less! Thank you again Jerome for discovering the bug and offering a patch!

Keep the suggestions, reports and fixes coming!

NEW: Solaris Package Companion v0.8.1 / Testing Tool v0.1

On the heels of the v0.8 release, Clive King was able to find a new bug introduced as a result of my attempting to make the code a little more in line with Korn Shell conventions. Clive, thank you for reporting the details! I have published an updated version as v0.8.1. As always, you can get all of the details at the OpenSolaris Solaris Package Companion Project Page

As is my tradition when a bug is found, I try and publish a little something extra as a mea cupla. This time is no different. In addition to version 0.8.1 of the Solaris Package Companion, I have also published a testing tool for the same.

The testing tool, called spc-test-v0.1.ksh is also available from the project page. This tool can test multiple versions of the tool against multiple repositories which is pretty cool when checking for regressions. There are currently 48 tests although tests can be easily added or removed as needed. It can optionally display the results to the screen, but by default it records them in a directory where a basic consistency check is performed to detect differences in output (for the same repository) resulting from the use of different versions of the tool. This is not intended to be an all encompassing test suite or even a piece of production code, but rather a basic sanity check to make sure the key functions are working as expected.

Thanks again, Clive!

Keep the suggestions, reports and fixes coming!

NEW: Solaris Package Companion v0.8

Wow, has time passed since my last posting. I promise to do a quick update soon as a lot has been happening over the last six months! In the meantime, I wanted to tell you all about a new version of the Solaris Package Companion (version 0.8) that is now available.

For those not familiar with the tool, here is a brief overview:

   The Solaris Package Companion is a small Korn shell script that allows you to ask
   quite a number of interesting questions about the relationships between Solaris 
   metaclusters, clusters and packages as well as their respective dependencies. Very
   often, answers to these kinds of questions are essential for the construction of 
   minimized systems as well as more generally for OS golden images.

   The goal of the Solaris Package Companion, or SPC for short, is to do all of the 
   hard work so you don't have to. SPC will create a cache of important facts by mining
   information from the various packaging files and directories to allow you to quickly 
   and easily obtain answers to a variety of questions such as:

     \* What clusters or packages are contained in a given metacluster?
     \* What packages are contained in a given cluster?
     \* What metacluster or cluster contains a given package?
     \* On what other packages does a given package or cluster depend?
     \* Which packages depend on a given package?
     \* … and so on…

New to this release is a tree view display method that allows you to list the contents of metaclusters and clusters in a more eye-friendly tree-view. Thanks to Fredrich Maney for contributing the idea and code! Here are a few examples from the project page showing what this looks like:

To see what packages are included in a cluster, just use the "-t" option:

$ ./spc-v0.8.ksh -v -r ./myrepository -t SUNWCssh
   [C] SUNWCssh                  Secure Shell
      [P] SUNWsshcu                 SSH Common, (Usr)
      [P] SUNWsshdr                 SSH Server, (Root)
      [P] SUNWsshdu                 SSH Server, (Usr)
      [P] SUNWsshr                  SSH Client and utilities, (Root)
      [P] SUNWsshu                  SSH Client and utilities, (Usr)

To see what packages and clusters are included in a metacluster, just use the "-T" option:

$ ./spc-v0.8.ksh -v -r ./myrepository -T SUNWCmreq | head -10
[M] SUNWCmreq                 Minimal Core System Support
   [C] SUNWCfca                  Sun ISP Fibre Channel Device Drivers
      [P] SUNWqlc                   Qlogic ISP 2200/2202 Fibre Channel Device Driver
      [P] SUNWemlxs                 Emulex-Sun LightPulse Fibre Channel Adapter (FCA) driver (root)
   [C] SUNWCfct                  Sun Fibre Channel Transport Software
      [P] SUNWfcsm                  FCSM driver
      [P] SUNWfctl                  Sun Fibre Channel Transport layer
      [P] SUNWfcp                   Sun FCP SCSI Device Driver
      [P] SUNWfcip                  Sun FCIP IP/ARP over FibreChannel Device Driver
   [C] SUNWCfmd                  Fault Management Daemon and Utilities

I would also like to thank Peter Pickford for sharing a fix for a bug that resulted in the tool not properly recording all dependencies under certain circumstances. Thank you! While I was at it, I also took a little time to clean up the code a bit.

You can find more information, examples and the source code on the project page.
