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.


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


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


Project News

  • November 18th, 2010
    • Updated some information on the page
    • Made substantial progress learning Pylons and MVC framework
  • October 22nd, 2010
  • October 14, 2010:
    • Meeting of previously named "ScriptFactory" broke into three seperate projects: Mozharness, BuildAPI and Release Simple Bugs -Mustafa
    • We will follow up with Armen on details of the Release Simple Bugs project and more on BuildAPI
  • Wednesday October 13, 2010:
    • The ScriptFactory group met today with Armen and Ctyler in a conference call
    • We will separate into two groups and tackle Mozharness, BuildAPI or Release Simple Bugs
