Re: Camping tutorials for education?
Scratch that, got everything working with 1.8.7-p173 and selinux disabled. I have to say, rack apps are pretty easy to deploy with passenger once you get the thing installed and working :P. @Jonathan - Re: your apache conf, I actually didn't need the directory directive and the execcgi option to get this to work. Why did you list it? So here's my TODO list: 1. Try to get it working with selinux enabled. 2. Put together a tutorial for the wiki (which one would you guys like to see it on? github?) 3. Look into performance and security. Would installing fastcgi or something similar speed passenger up any? On Wed, Jun 10, 2009 at 8:45 PM, David Suscodsu...@gmail.com wrote: OK, good to know.

Re: Camping tutorials for education?
2. Stable version The current version is 1.5 and is available from RubyForge. This is however a *really* old release, and there have been plenty of bug fixes in the repo. There's a 1.5.180 from _why's gem server which fixes some of them. The 1.9-version I have at gems.judofyr.net is just a rake gem ran from the latest why/camping (once in a while). This should be stable enough. In fact, as soon as I finish this little cleanup of the documentation (and get some more feedback from you guys) I will most probably release it as 2.0. (1.9 is the preview release of 2.0) 3. Rack Camping started depending on Rack when the work on 2.0 started. Right now, Camping uses Rack::Utils so it's currently not possible to run Camping without Rack. This should hopefully not cause any problems. 4. Servers At the moment I think the easiest solution is Phusion Passenger, which is an Apache or Nginx modules which can serve any Rack app. 5. Documentation Yes, we really need some documentation! This is actually what's blocking the 2.0 release. I have some suggestions (will try to post these as soon as possible, aka few hours). I'm not very god writing documentation, so if you want to help out we can agree on how to organize it. 6. Picnic While I haven't been to take a proper look at it, I think it's a very cool idea. Keep up the good work :-) //Magnus Holm On Tue, Jun 9, 2009 at 12:35, Dave Everitt dever...@innotts.co.uk wrote: I'm planning to use Camping to teach the basics of frameworks, and encourage new arrivals from web design to take up Ruby instead of (say) defaulting to PHP. To do this, I need a foolproof set of instructions for both the technicians (who have to install on all the studio machines) and the students. To go further, I'd like to get an opinion on the following: 1. SQLIte/ActiveRecord I've had some trouble getting Camping to write to an SQLite database as it should (post 'sqlite3 connection problem' has the details). To prepare instructions, I need to understand exactly why this is happening (in case it happens on a student's machine), so I'll persist and get it solved, somehow. 2. Obtaining the definitive current stable version What's the consensus on the definitive stable version? And where is it? The bleeding edge download from http://gems.judofyr.net/ is at 1.9.316, yet Picnic includes Camping 2.0 (which I thought didn't exist yet), but if I 'gem update' my 1.5 version, Camping remains at 1.5? I hope you can understand the confusion (on behalf of my future students) here. 3. Rack At which version (see [2]) did Camping start depending on Rack (as stated at: http://github.com/why/camping/tree/master)? Just out of interest, is it still possible to run a Camping app without it? 4. Comparing servers Is there any consensus on running Camping with: Apache, Mongrel, fast_cgi, plain old CGI, etc.? Which is the most efficient, future-proof, quickest/easiest to set up, and is there any information that charts the methods and differences? In a production environment, the URLs are obviously an issue here, so some mod_rewrite (or -like) examples would also be good. With all this I also want to lower the entry bar to Camping for new users by attempting some nice, simple documentation just to get people going, which is the thing I've been struggling to do myself.
