BuildAPI

Project Name

BuildAPI

Project Description

The BuildAPI project consists of generating analytic reports which can be used for a multitude of purposes such as performance and usage tests or discovering rogue buildbot slave machines. Moreover, it will require querying a database for the information on the BuildBot jobs, which will then be used to generate the necessary reports.

Project Details

• Updated Objectives (October 28th 2010) from Armenzg
• We will choose one of the following to do:
  • 1) Generate graphs, charts, CSVs and CPU totals for infrastructure load blog posts
    • a) This is very useful and could move us forward towards having this information being published publicly for consumption
    • b) I highly encourage this one as understanding the mental model behind it is easier
  • 2)Write a tool that analyzes our statusDB and figure out slaves that have been continually been burning jobs (sometimes it takes us several days to spot them)

* Objective: To analyze and create reports from BuildBot data for multiple purposes. These reports will generated from querying buildbot databases to get the necessary information about jobs.

• It will be used for purposes such as:

• identifying critical machines that should not be processing jobs
• discovering rogue slaves
• Generating reports on performance, usage, build times, downtime, and more

• This project uses Pylons framework:

• Pylons combines the very best ideas from the worlds of Ruby, Python and Perl, providing a structured but extremely flexible Python web framework.

• We will need a snapshot of the database to test our work. For examples of the "statusdb" see:
  • http://anamariamoz.wordpress.com/
  • https://bugzilla.mozilla.org/show_bug.cgi?id=604088

• We will be generating different graphs from:
  • http://oduinn.com/blog/2010/09/09/infrastructure-load-for-august-2010/
  • Armen suggested that one student works on the first graph, and the other works on the second graph
  • We will also be working on the documentation

Resources

• I have signed up for the mailing list at http://groups.google.com/group/pylons-discuss as there is a lot of archived information on Pylons and of course, I can post my own questions there
• Mozilla Software Engineering group (see BuildAPI wiki)
• Channels such as #build, #pylons and #seneca or irc.mozilla.org and irc.freenode.net

Project Plan

Goals for each release:

• 0.1
  • Complete a local installation of Python, Pylons, MySQL (with databases snapshots loaded) and google virtualization
  • Set up BuildAPI and be able to run the Paste server to use the pre-existing BuildAPI controllers
  • Create my own controller, models or views to test and understand Pylons concepts

• 0.2
  • Pull information from the database and display it on a webpage USING the MVC model and integrating with the provided query.py script
  • Would like to generate a simple graph from the information that is pulled from the database
  • Note: Still need to understand how JSON and Java is being used with the existing scripts. For now I am comfortable with the MVC model and understand how it works, in a practical sense, for the most part.

• 0.3
  • Be able to generate graphs, charts and CSVs from one of the databases based on CPU load and infrastructure load.

What Needs to be Learned

• Pylons Framework
  • Learned some Pylons, read chapters from The Definitive Guide to Pylons book and also have a practical understanding of the MVC model
• How to integrate GoogleAPI or another charting system with Pylons
  • And also how json works with the templates

Updated by Andrew Singh

Accomplishments

• Created my own "project" using a controller, model and template.
  • The model uses the existing query.py file but I added my own queries.
  • The controller is called project.py, imports my queries from the query.py file and renders the template project.mako with the query results
  • I have removed the json because I do not fully understand it and I am taking it step by step
• BuildAPI set up on http://iraq.proximity.on.ca
• Python, Mysql-Python, Google Visualizations API, BuildAPI installed locally on a virtual machine on my laptop
• Databases installed from sql dump file
• Able to run Paste server and BuildAPI pre-existing scripts
• Able to run in from both regularly and from a python virtual environment (used for testing)
• Created my own test script using a controller to display information from a selected table in the schedulerdb database

Issues

• Update: Resolved all below issues
  • I tried to install the same on our Seneca CDOT server: iraq.proximity.on.ca so that I could work off of the server but I ran into errors
  • Tried regular installation as well as using a python virtual environment
  • Serving content on iraq.proximity.on.ca
