I spent a couple of hours this morning debugging RubyGems unit test failures along with Jirapong Nanta. It was a fun exercise. We tracked down two issues and hopefully Jirapong found the experience useful to jump start his exploration of the IronRuby code base. I am open to helping others too. I have put the following notes at the bottom of [http://wiki.github.com/ironruby/ironruby/debugging](http://wiki.github.com/ironruby/ironruby/debugging) to ensure that we can have a productive session. Jirapong had done his homework, gotten RubyGems to work cleanly with MRI, and done a bit of debugging himself, which is why we had a productive session. Pair debugging with experienced IronRuby developers Some experienced IronRuby developers may be available to debug a problem with you. Watching over their shoulder can help a newcomer to the code base learn debugging tips and techniques. To make this a fruitful exercise, please follow the following guidelines: - ``` Send email to ``` removed\_email\_address@domain.invalid[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) asking if any experienced developer is available to help you - ``` Ensure that you can build and successfully run all of the ``` RubySpec[http://wiki.github.com/ironruby/ironruby/rubyspec](http://wiki.github.com/ironruby/ironruby/rubyspec) tests. - ``` Restrict the problems to pure Ruby code which is known to work ``` with MRI. Ensuring a clean working baseline functionality in MRI ensures that the problem truly in IronRuby. Without a known clean MRI baseline, the problem can be in a component other than IronRuby which you are as well-equipped to diagnose as anyone else. - ``` Set up a clean repro. Spend time ensuring that it is not a ``` configuration issue, and that the problem can be easily reproduced on other machines. Document detailed information about your platform, version of IronRuby, and the steps to repro the problem. - ``` Do basic debugging by yourself beforehand. This will ensure ``` that you get the most out of the session and can keep up with what’s going on over Live Meeting. - ``` Set up Live Meeting on your machine, ``` which will allow you to watch the debugging session. - ``` Add the experienced developer as a friend/buddy in some Chat ``` program so that you can ask questions during the debugging session.

Awesome idea! We don’t use these newfangled collaboration tools enough, so I’m all for whatever can make collaboration easier =) From: removed\_email\_address@domain.invalid [[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)] On Behalf Of Shri B.

Yes!, It has been very helpful to me. I can see what i need to prepare and looking for when get an error. I found the debugger method is very powerful - > > > and would be nice if It can auto load when Ruby.Console is start? encourage everyone to try & contribute Thank you, -Jirapong ---

I am planning on looking at bugs in some Ruby apps this week. If anyone wants to look over my virtual shoulder with Live Meeting as a way to jump start contributing patches[http://wiki.github.com/ironruby/ironruby/contributing](http://wiki.github.com/ironruby/ironruby/contributing) to IronRuby, let me know and we can plan a time that works for all. Times that work for me are 10-12am PST Wednesday, and most working hours on Thursday and Friday. The session will probably be a couple of hours, you will need to have Live Meeting working, and you should be able to do builds and run tests cleanly on your machine (see details below).
