This is a project definition that I put up for GSoC 2016. This helps students to get started researching the project.

The main things I give in here are:

• Background
• Where we came from, where we are and we are heading towards
• Goal
• Use case for developers
• Breakdown of components
• Rather than all aspects being mixed and not logically separate

-----------------------------------

Give Treeherder the ability to schedule TaskCluster jobs

A - Generate data source with all possible tasks

• Bug 1232005 - Let the gecko decision task generate a file with all the possible TaskCluster jobs that could have been scheduled for a given push
• We will need to post this artifact into the TC index so we can fetch it
• We will probably need to create a "latest" alias
• RISK: The structure of graphs is going to change; the artifact will change in format:
• https://bugzilla.mozilla.org/show_bug.cgi?id=1178516
• graph-generation details
• Alternative mentor for this section are: garndt

B - Teach Treeherder to use the artifact

• Fetch that artifact for every tree and update the "runnable api"
• RISK: The structure of graphs is going to change; the artifact will change in format:
• https://bugzilla.mozilla.org/show_bug.cgi?id=1178516
• graph-generation details

• This will require close collaboration with Treeherder engineers
• This work can be done locally with a Treeherder instance
• It can also be deployed to the “staging” version of Treeherder to do tests
• Alternative mentors for this section is: camd

C - Teach pulse_actions to listen for requests from Treeherder

• pulse_actions is a pulse listener of Treeherder actions
• You can see pulse_actions’ workflow in here
• Once part B is completed, we will be able to listen for messages requesting certain TaskCluster tasks to be scheduled and we will schedule those tasks on behalf of the user
• RISK: Depending if the TaskCluster actions project is completed on time, we might instead make POST requests to an API
