Question

For example I have this gem called Authlogic-openid, that plugin is outdated, no longer supported, and broken (let me know if you know any alternative by the way).

I wanted to make sure the test runs by keying ctrl+R on vendor/gems/authlogic-oid-1.0.4/test/acts_as_authentic_test.rb

[Please do not attempt to try my steps below, the gem itself was already broken apart so I had to earlier fix up some paths and required libraries… just imagine them in your head]

At first it returned

LoadError: no such file to load — ruby-debug

So I commented the line #3 in test_helper.rb, one that reads:

require "ruby-debug"

then I installed ruby-debug gem by

gem install ruby-debug

Then I added this into environment.rb

  config.gem 'ruby-debug'

Question #1: Are my steps above correct to start my Gem debugging quest?

Alright, so now the line I wanted to debug is in vendor/gems/authlogic-oid-1.0.4/lib/authlogic_openid/acts_as_authentic.rb line #157 (or around it) which reads:

  session_class.controller.params[:open_id_complete] && session_class.controller.params[:for_model]

So I typed “debugger” on top of it, it now reads:

debugger
session_class.controller.params[:open_id_complete] && session_class.controller.params[:for_model]

Then when I pressed ctrl + R again on vendor/gems/authlogic-oid-1.0.4/test/acts_as_authentic_test.rb, I got this output:

DEPRECATION WARNING: Please update config/database.yml to use 'database' instead of 'dbfile'. (called from parse_sqlite_config! at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/sqlite_adapter.rb:35)

Question #2: Are my steps correct to debug the code? Why did I get the error undefined method ‘logger’?

Bonus Question: Why do I get that deprecation warning? How to fix it?

my database.yml file as follows:

# MySQL.  Versions 4.1 and 5.0 are recommended.
#
# Install the MySQL driver:
#   gem install mysql
# On Mac OS X:
#   sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql
# On Mac OS X Leopard:
#   sudo env ARCHFLAGS="-arch i386" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
#       This sets the ARCHFLAGS environment variable to your native architecture
# On Windows:
#   gem install mysql
#       Choose the win32 build.
#       Install MySQL and put its /bin directory on your path.
#
# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.0/en/old-client.html

Thank you!

Answer 1

Try to run your testing server with the --debugger flag.

From the Rails README file:

Debugger support is available through the debugger command when you start your Mongrel or
Webrick server with –debugger. This means that you can break out of execution at any point
in the code, investigate and change the model, AND then resume execution!
You need to install ruby-debug to run the server in debugging mode. With gems, use ‘gem install ruby-debug’.

Regarding the deprecation warning.

DEPRECATION WARNING: Please update config/database.yml to use ‘database’ instead of ‘dbfile’.

It seems you use SQLite. You just need to replace the dbfile line in your config/database.yml with the database and the warning should gone.
