Camping list - Jun 2007 - Reloader paths/

after investigating why the reloader wasnt working , i discovered 2 probs, one
of which was sorta my fault (but will likely happen to others who make one-file
apps)

first, my app was like this:

#!/usr/bn/env ruby

%w{applib1 applib2 digest/md80 airbus}.each{|r| require r}}

if __FILE__ == $0
  Mongrel.config do
     handler ''/'', Camping.reloader.new(__FILE__)
  end
end


not exactly sure how it wraps the run request, since it mainly returns a
constant name. but even so, the files are already required. maybe reloader
should record the current $LOADED_FEATURES as soon as its loaded so even stuff
later in the require line gets recorded.. im not sure where camping draws the
line for ''too magic'', but i think its somewhere like
'' i havent seen a blaze mark on a tree in a few miles, but theres sort
of a path here, maybe made by native chipmunks, so im going to follow
it...''

even as i reworked the app structure on disk, to have a front layer that just
does the launching (defeating the single file thing) it still wasnt loading.

, its matching /^file.basename(scriptname)/,. so unless you have appname.rb then
appname/ for further stuff (which doesnt contain your entire app in a dir), it
breaks. one solution would be to expand the path of the requires, then compare
File.dirname..


anyone have any preferences on whether the former or the latter technique is a
less world-changing solution? would either one break/fix RV / TentSteak /
CampingServer?

No idea about TentSteak.  Here''s my parameterized kickstart method to  
run a Camping app under mongrel, webrick, or CGI (haven''t gotten to  
FCGI yet).  Anything clunky in there?  It''s kind of an early spitball  
at this point, so lots of room for improvement.

   def self.run_app(app_module, app_base = "app")
     case ARGV.first
     when "mongrel"
       puts "Running Mongrel in FCGI mode"
       require "mongrel/camping"

       app_module::Models::Base.threaded_connections = false
       server = Mongrel::Camping::start("0.0.0.0", 3301, "/# 
{app_base}/", app_module)
       puts "#{app_module} app is running at http://localhost:3301/# 
{app_base}/"
       server.run.join
     when "webrick"
       puts "Running in WEBrick mode"
       require ''webrick/httpserver''
       require ''camping/webrick''

       s = WEBrick::HTTPServer.new(:BindAddress => "0.0.0.0", :Port
=> 3301)
       s.mount("/#{app_base}", WEBrick::CampingHandler, app_module)
       trap(:INT) { s.shutdown }
       s.start
     else
       # Default to CGI.
       puts app_module.run
     end
   end
