Multiple Project Summary Reporting Standard - cctray xml feed

CCTray.xml is an RSS-like CI server build status xml feed, which is originally developed for CruiseControl.net.
ThoughtWorks declared it in a standard called “Multiple Project Summary Reporting Standard”, which now have become some kind of unofficial standard of CI server feed that is widely supported by all kind of popular CI servers.

You can find the feed as described below:

And according to cc_dashboard, there are some exceptions that are not included in the document.

  • An additional “Pending” activity
  • An additional “Unknown” status. I’ve seen Unknown reported by CruiseControl.rb when project builds are serialized (“Configuration.serialize_builds = true” set in .cruise/site_config.rb) and one build is waiting for another build to finish. I’ve seen Unknown reported by Hudson when a project is disabled.

The following is a patched version of Multiple Project Summary Reporting Standard.

Multiple Project Summary Reporting Standard

Introduction

Various Continuous Integration monitoring / reporting tools exist. Examples are:

These tools work by polling Continuous Integration servers for summary information and presenting it appropriately to users.

If a Continuous Integration server can offer a standard summary format, and a reporting tool can consume the same, then we get interoperability between reporting tools and CI Servers.

Description

Summary information will be available as a plain XML string retrievable through an http GET request.

The format of the XML will be as follows:

Summary

A single node, the document root, which contains 0 or many node.

Each may have the following attributes:






































































































name description type required
name The name of the project string yes
activity The current state of the project string enum : Sleeping, Building, CheckingModifications
yes
lastBuildStatus A brief description of the last build string enum : Pending, Success, Failure, Exception, Unknown yes
lastBuildLabel A referential name for the last build string no
lastBuildTime When the last build occurred DateTime yes
nextBuildTime When the next build is scheduled to occur (or when the next check to see whether a build should be performed is scheduled to occur) DateTime no
webUrl A URL for where more detail can be found about this project string (URL) yes

Clients that consume this XML should not rely on any optional attribute being present, and should degrade their functionality gracefully.
