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

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 script that can generate a simple graph or to be able to pull information from a database
  • 0.11 - Complete above script to generate a simple graph. At the moment I am able to pull information from the database. Further milestones to follow before 0.2.

• 0.2
  • To be updated shortly

• 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
• BuildAPI database structure
• How to integrate GoogleAPI or another charting system with Pylons

Accomplishments

• 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

• 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
• Will seek help
• I would also like to set up Pylons to be accessible on iraq.proximity.on.ca, which I understand can be done through several methods such as through http_proxy (Apache web server) - thus will also check with Chris Tyler and other regarding this

Project News

• What has been done so far
  • Please see my blog at: http://andrewasdesigned.blogspot.com/2010/10/beginning-previously-we-had-conference.html
  • I have been moving forward and have installed BuildAPI locally on my machine to test it out
  • Still need time to finish reading on Pylons!

• October 22nd, 2010
  • New schedulerdb snapshot available.
• 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
