Redmine

This is my apache configuration:

    FastCgiServer /data/redmine/public/dispatch.fcgi \
        -idle-timeout 120 -processes 2 \
        -initial-env RAILS_ENV=production \
        -initial-env PATH=/data/ruby/bin:/usr/bin \
        -initial-env LD_LIBRARY_PATH=/data/tools/lib \
        -initial-env RAILS_RELATIVE_URL_ROOT=/redmine

    Alias /redmine /data/redmine/public
    <Directory /data/redmine/public>
        Options Indexes ExecCGI FollowSymLinks

        RewriteEngine On
        RewriteBase /redmine
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteRule ^(.*)$ dispatch.fcgi

        AllowOverride all
        Order allow,deny
        Allow from all
    </Directory>

in redmine/config/environment.rb

    RedmineApp::Application.routes.default_scope = {
      :path => ENV['RAILS_RELATIVE_URL_ROOT'],
      :shallow_path => ENV['RAILS_RELATIVE_URL_ROOT']
    }

I've made a test with your change to environment.rb, and don't get the double sub-uri if I set the "Host name and path" (in application settings / General tab) to the host name only, without the sub-uri path (eg. redmine.host). Can you double check that?

I can confirm the problem. The workaround does help me!

Though I think I don't have the same situation. Hard to describe what my situation is, actually... ;-) Has something to do with passenger. At least I can say all worked fine except the emails. With this hack it also works for me with Redmine 3.1.0 and 3.2.0.

I'm wondering why prefix (or :script_name) gets populated. In my case Setting.host_name is set to redmine.colop.com, so there is no /something appended to the host. Links should be redmine.colop.com/something but actually get rendered to redmine.colop.com/something/something.

In my case config/additional_environment.rb and config/environments/production.rb are not modified. relative_url_root is not changed that way. And my httpd-conf contains:

<VirtualHost *:80>
    ServerName redmine.colop.com

    PassengerRuby             /home/redmine/.rvm/wrappers/ruby-2.2.1/ruby
    PassengerSpawnMethod      smart
    PassengerPoolIdleTime     300
    PassengerMaxRequests      500
    PassengerStatThrottleRate 5
    PassengerMinInstances     2

    DocumentRoot /var/www/html/redmine/public

    Alias /something /var/www/html/redmine/public
    <Location "/something">
        PassengerBaseURI /something
        PassengerAppRoot /var/www/html/redmine
    </Location>

    <Directory /var/www/html/redmine/public>
        Allow from all
        Options -MultiViews
        # Uncomment this if you're on Apache >= 2.4:
        #Require all granted
    </Directory>
</VirtualHost>

Does this configuratin inject the host into Redmine configuration? Why can it happen that :script_name is not empty?

At first time I setted
hostname to "host/redmine" in redmnine's preferences
(as redmine suggest, it show under input caption: "Example: host/redmine").

Then, when I saw URL like this "host/redmine/redmine" in mail,
so I changed hostname to just "host", but emails still contains double sub-uri in URL.

But hostname change works, if for example I set hostname to "host/" I got in email
"host//redmine/redmine", as you see it contains "//".

So may be to reproduce bug, you need at first change hostname to "host/redmine",
and then to "host".

Indeed

:script_name => ''

I add some logging into app/models/mailer.rb:

def self.default_url_options
    Rails.logger.error "Hi!!!!! It is me!!!!!!!!!!!!!!!!!!" 
    options = {:protocol => Setting.protocol}
    Rails.logger.error "!!!!!!!Setting.host_name.to_s '#{Setting.host_name.to_s}'" 
    if Setting.host_name.to_s =~ /\A(https?\:\/\/)?(.+?)(\:(\d+))?(\/.+)?\z/i
      host, port, prefix = $2, $4, $5

      Rails.logger.error "!!!!!!! '#{host}', '#{port}', '#{prefix}'" 
      options.merge!({
        :host => host, :port => port, :script_name => ''
      })
    else
      Rails.logger.error "!!!!!!!ELSE!!!! Setting.host_name '#{Setting.host_name}'" 
      options[:host] = Setting.host_name
    end
    options
  end

It prints:

Hi!!!!! It is me!!!!!!!!!!!!!!!!!!
!!!!!!!Setting.host_name.to_s 'hostname.net'
!!!!!!! 'hostname.net', '', ''

So prefix is empty, but not as empty string.

Because of

 
:script_name => prefix 

:script_name => ''
