Catalyst on DICE

The web interface for our new account management system, prometheus (which I’m mainly discussing in its own blog) uses the perl Catalyst MVC framework. The initial prototyping and development of prometheus was done on a DICE FC5 machine, with most of Catalyst installed from Extras. For some reason, last week seemed like a good point to move it to it’s eventual home architecture on Scientific Linux.

Let us be clear. Catalyst has a lot of dependencies. And by lot, I don’t just mean a few additional packages. On top of our standard DICE installation, an additional 73 perl modules are required to build, and use, Catalyst itself. Unfortunately for me, only 28 of those are actually available in the EPEL repository. Of the remainder, 6 of them were completely new to Fedora, and have now been packaged and will be submitted upstream. The last 39 are packages which exist in Fedora but which don’t have EPEL branches – at some point I should ask their maintainers about either doing so, or allowing me to comaintain an EPEL fork.

All that aside, a header to add catalyst support to a machine is available as ed/options/catalyst.h Feel free to tell me about any problems, or further missing packages (!)
