Nokogiri on a standard installation of Leopard is complain-y about a couple of old libraries:
“HI. You’re using libxml2 version 2.6.16 which is over 4 years old and has plenty of bugs. We suggest that for maximum HTML/XML parsing pleasure, you upgrade your version of libxml2 and re-install nokogiri. If you like using libxml2 version 2.6.16, but don’t like this warning, please define the constant I_KNOW_I_AM_USING_AN_OLD_AND_BUGGY_VERSION_OF_LIBXML2 before requring nokogiri.”
Aaron Kalin figured out how to fix this if you’re installing nokogiri as a system gem, but I want to use Bundler and keep my system gems down to the bare minimum. I figured out how to do this under Bundler 0.8.5.

I’m trying out Ruby Version Manager this week, and my first impression is that this is some cool technology. But I wasn’t able to figure out how to get it to install an older version of REE to get around this bug (the “Marshal.load reentered at marshal_load” issue).
Igor P’s solution is correct (just install REE 1.8.7-2009.10), but it took a little fiddling to figure out how to get RVM to use the older version of REE. Here’s how to do it:
wget -q http://rubyforge.org/frs/download.php/66162/ruby-enterprise-1.8.7-2009.10.tar.gz
rvm install ree-1.8.7-2009.10
I’m working on a Rails app that uses the ym4r_gm plugin, getting Google to do the geocoding for Thentic. I liked the idea of stubbing the web service call, because all those calls to an external service add up to over 20 seconds of test suite run time(!). That’s almost half of the 50 second run time of my unit tests (and 50 seconds is much too long for a unit test suite).
I found a good starting point at geokit stubbing for faster tests. I also wanted a way to stub a geocoding failure, and a way to prevent any unit tests from using the real geocoding web service.
Here’s how I did it.

The new features in Ruby on Rails 2.2.2 have been well documented, and I’m looking forward to using several of them on WhatYouAte.com. If you’re reading this you probably are too.
However, if you’re upgrading an existing project and you’re sticking with official releases (as opposed to edge Rails) like I am, your code probably needs some tweaking to work with Rails 2.2.2. Mine certainly did. Although there were a lot of failed tests with ugly stacktraces, there were only a few API changes in Rails that needed to be accomodated to fix them all. Here’s a list of the changes that broke my app, and what I had to do to get it working again.

I recently upgraded WhatYouAte.com to Rails 2.2.2. I had been using advice from the Rails Wiki’s HowToUseValidationsWithoutExtendingActiveRecord page. I was using a class based on the RailsWeenie code (that site is down now) and it stopped working. Here’s a new replacement hack that works almost identically.
