Mongrel users - Jun 2006 - mongrel_upload_progress & plugin question in general

Hello,

So, I grabbed the mongrel_upload_progress code from subversion  
because I really need something similar for a project I am working  
on. Anyway, I installed the gem and can''t figure out a few things.

1) I''m not sure what Upload < GemPlugin::Plugin
"/handlers" is for

2) How to call the Progress < GemPlugin::Plugin "/handlers"
handler.

While I was trying to figure it out, I wrote my own test plugin to  
mess around with the general plugin system and what I think it is is  
that the handlers aren''t registering with a particular uri. In the  
Rdoc for mongrel there is the following code:

require ''mongrel''

  class SimpleHandler < Mongrel::HttpHandler
     def process(request, response)
       response.start(200) do |head,out|
         head["Content-Type"] = "text/plain"
         out.write("hello!\n")
       end
     end
  end

  h = Mongrel::HttpServer.new("0.0.0.0", "3000")
  h.register("/test", SimpleHandler.new)
  h.register("/files", Mongrel::DirHandler.new("."))
  h.run.join

Now, the key thing here is the h.register which associates a uri with  
a handler (or the method uri). I don''t see anything like that  
happening with the gem plugins. Am I missing something? What would be  
the "GemPlugin" way to register a uri with a handler. I''m not
even
sure that it should be associated with the plugin, in which case do I  
have to modify mongrel_rails ?

Thanks for any pointers or suggestions on where to look.

Hi,

look for documentation for Mongrel::Configurator.
It has method plugin that returns an instance of particular handler:

...
uri ''/whatever'', :handler =>
plugin(''/handlers/progress'', options)
...

if you have
class Progress < GemPlugin::Base ''/handlers''

then
plugin(''/handlers/progress'', options)

is the same as

Progress.new(options)

Then, if you use mongrel_rails, you can use -S switch to insert
additional configuration into
RailsConfigurator, which is a subclass of Mongrel::Configurator

In your script write:

uri ''/whatever'', :handler =>
plugin(''/handlers/progress'', options)

Hope this helps.

What was useful for me to figure this out:
- reading the rdoc for mongrel and gemplugin
- reading the thread on progress plugin on this list
- reading the source of mongrel_rails
- reading the source of another plugin, but I don''t remember which one
it was
