Redmine

What do you have in your config/environment.rb file?

@# Be sure to restart your web server when you modify this file.

1. Uncomment below to force Rails into production mode when
2. you don't control web/app server and can't set it the proper way
3. ENV['RAILS_ENV'] ||= 'production'

1. Specifies gem version of Rails to use when vendor/rails is not present
   RAILS_GEM_VERSION = '2.3.5' #unless defined? RAILS_GEM_VERSION

1. Bootstrap the Rails environment, frameworks, and default configuration
   require File.join(File.dirname(FILE), 'boot')

1. Load Engine plugin if available
   begin
   require File.join(File.dirname(FILE), '../vendor/plugins/engines/boot')
   rescue LoadError # Not available
   end

Rails::Initializer.run do |config| # Settings in config/environments/* take precedence those specified here

1. Skip frameworks you're not going to use
2. config.frameworks -= [ :action_web_service, :action_mailer ]

1. Add additional load paths for sweepers
   config.load_paths += %W( #{RAILS_ROOT}/app/sweepers )

1. Force all environments to use the same logger level
2. (by default production uses :info, the others :debug)
3. config.log_level = :debug

1. Enable page/fragment caching by setting a file-based store
2. (remember to create the caching directory and make it readable to the application)
3. config.action_controller.cache_store = :file_store, "#{RAILS_ROOT}/tmp/cache"

1. Activate observers that should always be running
2. config.active_record.observers = :cacher, :garbage_collector
   config.active_record.observers = :message_observer, :issue_observer, :journal_observer, :news_observer, :document_observer, :wiki_content_observer

1. Make Active Record use UTC-base instead of local time
2. config.active_record.default_timezone = :utc

1. Use Active Record's schema dumper instead of SQL when creating the test database
2. (enables use of different database adapters for development and test environments)
3. config.active_record.schema_format = :ruby

1. Deliveries are disabled by default. Do NOT modify this section.
2. Define your email configuration in email.yml instead.
3. It will automatically turn deliveries on
   config.action_mailer.perform_deliveries = false

config.gem 'rubytree', :lib => 'tree'

1. Load any local configuration that is kept out of source control
2. (e.g. gems, patches).
   if File.exists?(File.join(File.dirname(FILE), 'additional_environment.rb'))
   instance_eval File.read(File.join(File.dirname(FILE), 'additional_environment.rb'))
   end
   end

Run this from your redmine installation directory:

Oh, please wrap the output in pre tags so Redmine won't parse it.

I'm not a guru, sort of learning myself actually, but I don't see anything obvious yet. What about the contents of your thin config file?

This is the thin config file but I don't think, there is the problem because with this config file it worked previously.

--- 
pid: /var/run/thin/redmine.pid
group: www-data
wait: 30
timeout: 30
log: log/thin.log
max_conns: 1024
require: []

environment: production
max_persistent_conns: 512
servers: 4
daemonize: true
user: www-data
socket: /var/run/thin/redmine.sock
chdir: /var/customers/webs/web4/vhost/kaimei-projects.ath.cx/redmine 

Last idea:

Uncomment ENV['RAILS_ENV'] ||= 'production' within config/environment.rb and restart nginx/thin. I'll look back over everything later, but hopefully someone else spots the issue before then.

Same result.

Here is the config/environment.rb in pre tags

# Be sure to restart your web server when you modify this file.

# Uncomment below to force Rails into production mode when 
# you don't control web/app server and can't set it the proper way
# ENV['RAILS_ENV'] ||= 'production'

# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.3.5' #unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')

# Load Engine plugin if available
begin
  require File.join(File.dirname(__FILE__), '../vendor/plugins/engines/boot')
rescue LoadError
  # Not available
end

Rails::Initializer.run do |config|
  # Settings in config/environments/* take precedence those specified here

  # Skip frameworks you're not going to use
  # config.frameworks -= [ :action_web_service, :action_mailer ]

  # Add additional load paths for sweepers
  config.load_paths += %W( #{RAILS_ROOT}/app/sweepers )

  # config.action_controller.cache_store = :file_store, "#{RAILS_ROOT}/tmp/cache" 

  # Activate observers that should always be running
  # config.active_record.observers = :cacher, :garbage_collector
  config.active_record.observers = :message_observer, :issue_observer, :journal_observer, :news_observer, :document_observer, :wiki_content_observer

  # Make Active Record use UTC-base instead of local time
  # config.active_record.default_timezone = :utc

  # Deliveries are disabled by default. Do NOT modify this section.

  config.action_mailer.perform_deliveries = false

  config.gem 'rubytree', :lib => 'tree'

  # Load any local configuration that is kept out of source control

  if File.exists?(File.join(File.dirname(__FILE__), 'additional_environment.rb'))
    instance_eval File.read(File.join(File.dirname(__FILE__), 'additional_environment.rb'))
  end
end

I'm guessing that's the contents before uncommenting the line?

Do you have more than one copy of Ruby installed?

Here's a quick way to check:

for i in `find / | grep bin/gem | grep -v gemto`; do echo && echo -n $i && $i list --local; done

It's kind of an ugly one-liner, but it should show if you have more than one copy of Ruby installed. I do because I am trying out Ruby Enterprise Edition (
/usr/local/bin/gem ). Here is my output:

Rats. Forgot to wrap that last bit in pre tags. Oh well.

If that doesn't help, I looked around and found this:
http://www.ruby-forum.com/topic/201603

Sounds like having two versions of rack might be the culprit. Perhaps trying removing 1.2.1 (leaving just 1.0.1) and try again.

This seems to also back it up.

Thank you.

I uinstalled rack 1.2.1 an now thin is starting without any problems.

Thank you.

You're welcome, glad it helped!
