Mozharness

Project Name

Mozharness

Project Description

Imagine that we did not have to touch the Mozilla buildbot factories but instead we maintained a bunch of script for all the different jobs they run?

It would be good if we could create scripts that told a machine how to generate an optimized build, a debug build, unit tests, talos runs, locale repackages. If you look in the tools/scripts repo you can see that we have a simple shell file to do this for the fuzzing automation. The buildbot factory that calls it is called mozharness and it is very simple.

mozharness is a single factory that buildbot can run; within mozharness, a script is selected for a specific job. This moves the job-definition responsibility out from buildbot; by separating the pieces, you avoid excessive complexity in buildbot and also open up the possibility of running mozharness manually (e.g., by a developer, to test something)

Project Details

• Objective: Improve efficiency while lowering the entry level knowledge required from new developers to get involved

• http://hg.mozilla.org/users/asasaki_mozilla.com/mozharness

• requirements: pylint and coverage

• ./unit.sh to run unit test coverage

• scripts directory contain scripts

• documentation is required

• API is changing - WIP in https://bugzilla.mozilla.org/show_bug.cgi?id=574473

• scripts written in python

• separate framework - which buildbot calls

 What are we building?

• Profile Build

• Debug Build - For OS (Mac, Linux, Windows, 32/64 etc)

• Packaged Test - contains test for the build

• Tests - Mochitests, Reftests, xpcshell, ... 10 in total
  • l10n builds

  The problem that mozharness solves:

• buildbot uses a "factory" to run a job

• there are (becoming) too many different "factories" within buildbot

Project Plan

Goals for each release:
