Rails - Apr 2009 - Problem when migrating from rails 2.2.2 to rails 2.3.2 on linux SLES10 + apache 2

When I do this migration and I want to launch mongrel_cluster
(mongrel_rails cluster::start), I get an error :
** Starting Mongrel listening at 127.0.0.1:3010
** Starting Rails with production environment...
** Mounting Rails at /test...
/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/
dependencies.rb:440:in `load_missing_constant'': uninitialized constant
ActionController::AbstractRequest (NameError)
......................................
No plugins. It''s just a basic rails app showing only the standard
index page.

Thanks for your help if someone has an idea.

Definitely sounds like a plugin or monkey patch issue to me -
AbstractRequest was a class that disappeared in rails 2.3. I''d start
by searching your code for that and see what comes up.

Thanks a lot for your reply Fred. First, I checked with my app : I
started it fine without the cluster (script/server -e production) and
it worked nice. Then I created a basic app without any plugin (rails
test), showing only the standard page Welcome aboard. Again it worked
fine without the cluster. When I create it (mongrel_rails
cluster::configure -e production -p 3010 -N 2 -c /my/path/test -a
127.0.01 --prefix /test) and launch it (mongrel_rails cluster::start)
then I get the error reported in log/mongrel.3010.log. So wouldn''it be
mongrel_cluster which causes the problem ?

I''m using mongrel (1.1.5) and mongrel_cluster (1.0.5) which seem to be
the last versions. I got a bit deeper in the bug analysis. It''s a bit
trickiest than I first thought. In fact, I have in my cluster config
file (config/mongrel_cluster.yml) a line : prefix: /my_app_name. If I
delete this line, the cluster will start alright and I have no more
errors ! But I need this line so that in my apache conf file, I use
the <Proxy balancer://my_app_name> line and the rewrite line
(RewriteRule ^/my_app_name(.*)$ balancer://my_app_name%{REQUEST_URI}
[P,QSA,L]).

It used to work perfectly when I was in rails 2.2.2

Any idea ?

Thanks anyway for your kind help.

Ah - mongrel does

        ActionController::AbstractRequest.relative_url_root = ops
[:prefix] if ops[:prefix]

if :prefix is set.

These days I think you  just set on
ActionController::Base.relative_url_root

Give that that''s all the prefix option seems to do, you could not pass
it to mongrel and set it in your app''s environment

I have 2 rails apps on that server. I didn''t get from your answer what
I shall do on the apache conf file and what I shall do on my rails''
apps (and in what file : environment.rb ?)

Thanks.

I finally got the solution on the web... Thanks to P. Leonhardt and C
Nolte posts. Here is the workaround :

Copy this file in my_rails_app/config/initializers :

abstract_request.rb

module ActionController
  class AbstractRequest < ActionController::Request
    def self.relative_url_root=(path)
      ActionController::Base.relative_url_root=(path)
    end
    def self.relative_url_root
      ActionController::Base.relative_url_root
    end
  end
end

Hope this may help someone else.

Thanks again, my server is working fine now.

Hi,

Thanks, it solved my problem. Although it looks like a hack to me.
Isn''t
this a bug in mongrel_service? Should we report it?

As of today I am using Ruby 1.8.7, Rail 2.3.5 and Rubygems 1.3.5. As for
Mongrel: mongrel (1.1.5) and mongrel_service (0.3.4) and the problem still
exists.
