For a while I had been using Strawp’s Azureus PHP Control Layer and the HTML Web UI plugin. Neither of these provided all the features I wanted though, so I developed my own. Azureus on Rails

• displays detailed information about each torrent,
• allows torrent and file priorities to be adjusted,
• supports stopping, starting, pausing and removing torrents,
• allows torrents to be uploaded or added by url
• and has a feed of the downloading and seeding torrents

The Azureus on Rails Wiki contains the full list of supported features as well as screenshots and installation instructions.

It adds a console to the bottom of the Firefox window which shows you the log for the current page (including the ability to click on an error and have the source line that caused it hightlighted) and allows you to point-and-click to inspect any DOM element in the page. It can also inspect XMLHttpRequest calls and has a Javascript console.

To avoid having to manually escape every attribute value in rxml templates, I’ve put together a plugin that fixes this issue. Download rails_fixes.zip and extract it to your vendor/plugins directory (to create a new rails_fixes directory). The plugin replaces the _insert_attributes method of Builder::XmlMarkup with one that escapes the values.

The venue was Easthampstead Park in Bracknell (again). This year’s theme was Cirque Noel.

Unfortunately, I couldn’t find one, so I had to write my own instead. The result, TZInfo, is now available at RubyForge.

Edit Bugzilla/BugMail.pm. Find the NewProcessOnePerson sub. There is a section that sets several values in the $substs hash. The new attributes you want to show need to be added to $substs. The attributes of the bug can be found in $values (named the same as the columns in the bugs table). The following example makes the bug product and component attributes available:

$substs{"summary"} = $values{'short_desc'};
$substs{"reasonsheader"} = join(" ", @reasons);
$substs{"reasonsbody"} = $reasonsbody;
$substs{"space"} = " ";

# Added the following lines to allow product and component to be used in bug mail
$substs{"product"} = $values{'product'};
$substs{"component"} = $values{'component'};


Once this change is made to the code, edit the newchangedmail parameter (bug changed email template) through the edit parameters admin screen. You will now be able to use the new values added to $substs as %name%. For the above example, %product% and %component% can now be added to the template.

The extension allows the table names in the from section of queries to be replaced with subqueries specified by ActiveRecord classes. The subqueries can do anything that can be done with a view. ActiveRecords using subqueries can be eager loaded with includes like any normal ActiveRecord. This allows group bys and aggregate functions to be used without having to write a custom find_by_sql method or load in lots of data.

It looks like Windows Vista (Longhorn) may now support proper symbolic links on files as well as directories. A simple API allows links to be created.
