port sbsm/steinwies.ch to use the rack webserver

Adapt Gemfile and doc/index.rbx to rack. Installing needed bundles with Ruby 2.3 via /usr/local/bin/bundle install --path vendor/bundle. Starting it using /usr/local/bin/bundle exec ruby doc/index.rbx. Copying etc/config.yml to ~/git/steinwies.ch/etc.

Added the call method to to src/util/app.rb. Now it displays the index page, but hangs afterwards unless I insert a binding.pry statement just before the last statement in the call method. Also the URL is not parsed correctly. Also the CSS is not loaded. Also the content-type is not set correctly to text/html;charset=UTF-8. Adding a doc/config.ru to be

After debugging this problem with httpfox, if shows clearly, that GET /steinwies.css HTTP/1.1 via the URL http://resources/steinwies.css fails. Must correct the way how rack and sbsm interact to return a the complete URI.

While trying to debug this problem, I did set a binding.pry statement in the htmlgrid/lib/link.rb. This throws an error, as pry i not available. Starting bin/steinwies process also via bundle exec and not via daemontools.

Installing Apache passenger with the help of the following tutorial: https://www.phusionpassenger.com/library/install/apache/install/oss/rubygems_rvm/

Created a /etc/apache2/modules.d/22_mod_passenger.conf with the following content: 

   LoadModule passenger_module /home/niklaus/git/steinwies.ch/vendor/ruby/2.3.0/gems/passenger-5.0.30/buildout/apache2/mod_passenger.so
   <IfModule mod_passenger.c>
     PassengerRoot /home/niklaus/git/steinwies.ch/vendor/ruby/2.3.0/gems/passenger-5.0.30
     PassengerDefaultRuby /usr/local/bin/ruby231
   </IfModule>

Removed obsolete /usr/local/bin/passenger of April 2016

Resuming: steps were

  • /usr/local/bin/bundle install --path vendor
  • /usr/local/bin/bundle exec passenger-install-apache2-modul
  • /usr/local/bin/bundle exec passenger-config validate-install
  • /usr/local/bin/bundle exec passenger-memory-stats

Now creating a new /etc/apache2/vhosts.d/steinwies_rack.conf. The apache server now does now start, but gives the following error for Steinwies.

Configuration for Steinwies is Attach:steinwies_rack.conf.txt.

Stopped the Apache web server and added the following conf file /etc/nginx/sites-enabled/steinwies_rack. Attach:steinwies_rack.txt. Restarted nginx and now I get the Umlaut correctly, but still failures to load the css. (The page is shown only after a timeout of about 120 seconds)

Umlauts are correct now.

Zeno added the proxy module to Apache. Stopped nginx and restarted Apache with the changed config. This seems to work.

Apache Funtoo mod_proxy setup

  1. http://dev.ywesee.com/Apache/ModProxy
  2. sudo emerge =apache-2.2.31
  3. Als Bestätigung: 'sudo updatedb' danach 'locate mod_proxy.so'.

Virtualhost for mod_proxy

<VirtualHost *:80>
  Servername steinwies.ngiger.ch
  ServerAlias www.steinwies.ngiger.ch *.steinwies.ngiger.ch
  DirectoryIndex index.html index.rbx
  DocumentRoot /var/www/steinwies.ch/doc
  ProxyPass / http://127.0.0.1:9191/
  ProxyPassReverse / http://127.0.0.1:9191/
  ErrorLog  "|/usr/sbin/cronolog -l /var/www/steinwies.ch/log/error_log /var/www/steinwies.ch/log/%Y/%m/%d/error_log"
  CustomLog "|/usr/sbin/cronolog -l /var/www/steinwies.ch/log/access_log /var/www/steinwies.ch/log/%Y/%m/%d/access_log" combined
</VirtualHost>

Found the culprint for the missing css_link. In lookandfeel.rb _collect_resource uses the empty @session.server_name variable. Must set this variable correctly. This is done.

Apache proxypass work now. But calling steinwies.ngiger.ch now returns text/plain instead of html and I see, that loading the favicon.ico failed.

After some hard debugging found out that an exception in the drb-process did not get displayed correctly. Now i see a nice backtrace like 

NoMethodError at /
undefined method `bytesize' for nil:NilClass
Ruby 	/usr/local/lib/ruby/2.3.0/cgi/core.rb: in out, line 353

Traceback (innermost first)

    /home/niklaus/git/sbsm/lib/sbsm/request.rb: in process
                drb_process()

Saved work with commits to branches rack:

Must fix tomorrow the problem, that text/plain is returned insted of text/html.

See also: http://dev.ywesee.com/Apache/ModProxy. Apache config /etc/conf.d/apache2 has the following line for gentoo: 

  APACHE2_OPTS="-D RUBY -D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D PROXY -D PROXY_HTML"

Afterwards sudo emerge =apache-2.2.31. Confirmed using sudo updatedb &&locate mod_proxy.so
