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. Dave
I''d definitely be interested in seeing any work you do with this. Having it up on the wiki would be nice too. I''m still trying to figure out deployment with camping 1.5. I''ve experimented with 1.9.316 and rack but have yet to get an app to work with that. The same with Picnic.

The same with Picnic.Been meaning to write a quick overview of how I did it for you (as documentation is super sparse still). Briefly: (1) Read the passenger user guide at: http://www.modrails.com/documentation/Users%20guide.html I installed passenger from a gem but see the user''s guide if you need to install on debian using apt (it is in the Ubuntu repositories already). Similarly rack is from a gem, and I use the same version of camping as you (from Judofyr''s gem server). (2) Try and get the "hello world" from the passenger user guide to work for you. (3) Then try and get the blog example working that is shipped with camping. Here is a config.ru that works for that: require ''rubygems'' require ''rack'' require ''camping'' require ''blog'' Blog::Models::Base.establish_connection :adapter => "sqlite3", :database => "/home/jonathan/.camping.db" run Blog Change the database path to one you have on your system. You may need something like: Blog::Models.create_schema :assume => (Blog::Models::Post.table_exists? ? 1.0 : 0.0) before "run blog" if your sqlite database doesn''t yet have the schema for the blog example. (4) And the apache config that I used was something like: <Directory /> Options ExecCGI FollowSymLinks AllowOverride all Allow from all </Directory> <VirtualHost *:80> ServerName www.rackexample.com DocumentRoot /var/www/blog/public </VirtualHost> You may need to edit your hosts file so that www.rackexample.com resolves to your apache server. (5) Let us know how it goes... Regards, Jonathan
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 <deveritt at 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.

sounds like a work in progress, then... I''ll stick with 1.5 until there''s a definitive stable higher number (opinions?). Just need to solve the sqlite3 issue. Anyone know what setup the ''cheat'' Camping app uses (which I like, contribute to and use): http://cheat.errtheblog.com ? Working live examples are a good start. I still need some specific answers to the original points so I can make up a working setup just for beginners to get going, so any precise feedback there would be welcome - no hurry. My short-term aim is just(!) to get the blog example working in Camping 1.5 with sqlite3 on OS X with Ruby 1.8.6, as a CGI. The bottom line is, I love the whole concept of Camping, and want to help people new to web development (often from a design background, and in my case, students) start using it.> I''d definitely be interested in seeing any work you do with this. > Having it up on the wiki would be nice too. > > I''m still trying to figure out deployment with camping 1.5.

I''m trying to get passenger working presently, once I do I''ll let you know how the rest of it goes. When I try to load the module in the apache conf I get the following error: Cannot load /usr/lib/ruby/gems/1.8/gems/passenger-2.2.2/ext/apache2/mod_passenger.so into server: /usr/lib/ruby/gems/1.8/gems/passenger-2.2.2/ext/apache2/mod_passenger.so: failed to map segment from shared object: Permission denied I''m assuming it''s an SELinux problem, has anyone run into it before?

I''ve disabled SELinux to see if I could get any farther.
I managed to get passenger installed and working, however a fancy
passenger generated page is telling me the app couldn''t be started due
to this error:
`require'':
/usr/local/lib/ruby/gems/1.9.1/gems/camping-1.9.316/lib/camping.rb:11:
syntax error, unexpected tLABEL (SyntaxError)
p[0]==?/?@root+p:p end;def URL c=''/'',*a;c=R(c,...
It''s the same thing when I try to rackup the .ru file, and the same
when I try to execute this little bit of code:
#!/usr/bin/env ruby -rubygems
gem ''camping'', ''>=1.9.316''
%w(rack camping).each { |lib| require lib }
puts ''done''
I''m tried reinstalled camping 1.9.316 but that didn''t change
anything.
Any ideas?

Unfornately, Camping doesn''t (yet) work on Ruby 1.9.1. Unless someone else want to try now, I''m going to have a look at it *after* 2.0 is released. //Magnus Holm On Wed, Jun 10, 2009 at 22:30, David Susco <dsusco at gmail.com> wrote:> I''ve disabled SELinux to see if I could get any farther. > > I managed to get passenger installed and working, however a fancy > passenger generated page is telling me the app couldn''t be started due > to this error: > > `require'': > /usr/local/lib/ruby/gems/1.9.1/gems/camping-1.9.316/lib/camping.rb:11: > syntax error, unexpected tLABEL (SyntaxError) > p[0]==?/?@root+p:p end;def URL c=''/'',*a;c=R(c,... > > It''s the same thing when I try to rackup the .ru file, and the same > when I try to execute this little bit of code: > > #!/usr/bin/env ruby -rubygems > gem ''camping'', ''>=1.9.316'' > %w(rack camping).each { |lib| require lib } > puts ''done'' > > I''m tried reinstalled camping 1.9.316 but that didn''t change anything. > Any ideas? > > Dave > > On Wed, Jun 10, 2009 at 10:39 AM, David Susco<dsusco at gmail.com> wrote: > > I''m trying to get passenger working presently, once I do I''ll let you > > know how the rest of it goes. > > > > When I try to load the module in the apache conf I get the following > error: > > > > Cannot load > /usr/lib/ruby/gems/1.8/gems/passenger-2.2.2/ext/apache2/mod_passenger.so > > into server: > /usr/lib/ruby/gems/1.8/gems/passenger-2.2.2/ext/apache2/mod_passenger.so: > > failed to map segment from shared object: Permission denied > > > > I''m assuming it''s an SELinux problem, has anyone run into it before? > > I''ve done the following already, so it hasn''t helped: > > > http://www.modrails.com/documentation/Users%20guide.html#_the_apache_error_log_says_that_the_spawn_manager_script_does_not_exist_or_that_it_does_not_have_permission_to_execute_it > > > > Dave > > > > > > On Tue, Jun 9, 2009 at 11:28 AM, Jonathan Groll<lists at groll.co.za> > wrote: > >> Hi David, > >> > >> On Tue, Jun 09, 2009 at 09:29:22AM -0400, David Susco wrote: > >>> > >>> I''d definitely be interested in seeing any work you do with this. > >>> Having it up on the wiki would be nice too. > >>> > >>> I''m still trying to figure out deployment with camping 1.5.

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 Susco<dsusco at gmail.com> wrote:> OK, good to know.

Why did you list >it?You don''t need the execcgi, and the reason I give the directory directive is to set the permissions to allow, deny just for that directory (by default all my permissions are set to deny,allow for extra security). So skip the <directory> section if you don''t need it.>3. Look into performance and security.

It only makes sense to my mind to have one thing managing your ruby processes. Cheers, Jonathan.
@Julik: I agree about the 1.5.180 but it would be good to have it become ''official'' - the main problem is that many of the Camping links out there don''t refer to it, so people are downloading 1.5, trying the examples and having some problems e.g.: "I''ve had a lot of people contact me asking questions about errors and issues with content from my presentation or from conversations with them when really the only issue was that they were on 1.5 and needed to be on trunk." (2008, Keeping Camping going: msg#00008 lang.ruby.camping.general) - Jeremy McAnally He also has a nice Camping presentation (also in PDF) from 2007: http://slideshow.rubyforge.org/camping.html My own tutorial materials will evolve as I use Camping, and I''ll share them if things turns out okay. At present, I''m using it to generate static pages for prototyping a website, a purpose for which it works very well (a Camping niche market!?). As soon as I get the blog example working well with 1.5.180, I''ll write that up too. Then on to 2.0? The only thing holding me back there is getting Rack up and running and playing nicely with Apache. So far I''ve just seen (and reversed) the lobster from the rack gem, but have yet to make time to do the latter. In order to get a more complete picture, I spent most of last week researching (and trying) other more compact Ruby frameworks out there (http://wiki.ramaze.net/Home#other-frameworks). It seems Ramaze and Sinatra have the edge when it comes to nice and informative websites. Jeremy McAnally''s Vintage also seem okay, but I''m not sure about Wuby and some of the others have very poor documentation or web presence. I still like Camping, but there''s a way to go if we''re going to match the Sinatra or Ramaze sites, and that''s something to which I''d certainly like to contribute. - Dave Everitt> Well if Magnus has indeed released 1.5.180 then this is the latest > baseline stable.
