This Week in Edge Rails

December 6-December 12, 2008 Edition

Here’s your weekly roundup of the action out on the edge, where the code is exciting and sometimes even stable. There were only 32 commits this week; perhaps we’re going into a bit of year-end hibernation.

Memory Improvements

A couple of memory leaks got squashed this week. There was one that occurs in Rails 2.2 when you set config.log_level = :warn (this fix has been applied to the 2-2-stable branch as well as to edge) and one that turns up when you call reset_session in an around filter (this fix is on edge, and will be ported to 2.2 soon). commit commit

Application Templates

There was a bit of cleanup work on the application template feature that was introduced last week. This included support for installing plugins as git submodules, a couple of small cleanup items, and a rake task to apply a template to an existing application . With this task, you can now run


rake rails:template LOCATION=~/template.rb

And the changes indicated in the template will be layered on top of whatever code the project already contains.

I18n Cleanup

A few more bits of the Rails infrastructure are now exposed to internationalization, including connectors in Array#to_sentence and separators in Active Record validation messages . Also of interest to the international Rails community is a patch to add an ActiveSupport::Multibyte::Chars#ord method to properly return the Unicode value of the first character in a string.

Odds and Ends

There’s a new version of the memcache-client (1.5.0.5) bundled with edge Rails. This fixes some bugs in the original 1.5 and adds better support for failover and timeouts. You can read more about it on the Lighthouse ticket commit

Active Record’s to_xml support gets just a little bit more flexible with the addition of a :camelize option, which converts all of the column names in the output to camel case. commit

If you test a lot of view code that uses partials, you’ll be happy to know that assert_template now takes a :partial option that can look for them in the output directly. commit

And finally, there’s a patch that has not been applied to Rails yet, but that you might want to go look at in Lighthouse – it adds support for HTTP status code 418 so that Rails can conform to RFC2324 . I’m sure the core team would welcome further discussion of this change.
