[Catalyst] Migrating mod_perl app to Catalyst

[Catalyst] Migrating mod_perl app to Catalyst

Does anyone have any advice for migrating a large mod_perl app that has no
tests to catalyst?

I already know of Catalyst::Controller::WrapCGI which seems to be a good
start.

Thanks,
Michael

Hans Dieter Pearcey: Write some tests with Test::WWW::Mechanize first; they should be relatively easy to port to Catalyst tests once you swap it in. hdp.
Matt S Trout: Assuming your app doesn't use apache specific stuff. What I tend to recommend in such cases is to start writing new functionality in Catalyst as FastCGI and just map chunks of the URI space across to the new stuff. When you need to significantly alter the old code, port it first. Eventually you'll just have a Catalyst+FastCGI codebase, and you'll have had working code at every stage. -- Matt S Trout Catalyst and DBIx::Class consultancy with a clue: Technical Director
Jay Shirley: I've done similar things, and my new method is to have a two tiered application where my Cat app sits in front of legacy, and on unhandled URLs throws a 404. The front-end proxy (Varnish, in my case) then restarts the request against the next backend, which is the mod_perl system. Then, when I put in new features in Catalyst if the URL is changed I can simply put in a permanent redirect and everything just works. This is roughly a new technique, and lacking some fine tuning points, but so far
